Description

  The present invention relates to a drum-type washing machine that stores laundry in a drum and performs washing.

  2. Description of the Related Art A drum type washing machine that stores laundry in a substantially cylindrical drum rotatable around an axis extending in a substantially horizontal direction and performs washing is known. This type of washing machine has, for example, an outer tub that surrounds the outside of the drum. By rotating the drum in a state where a predetermined amount of water is stored in the outer tub, the laundry in the drum is drummed. Washing can be performed by repeatedly performing an operation (slap washing) such as lifting by a baffle protruding from the inner surface and naturally falling from a certain height toward the water surface.

  In a conventional general drum-type washing machine, for example, a drum and an outer tub are arranged in a housing in a state where respective end faces are front and rear. An outer lid that is opened and closed when loading and unloading laundry is provided on a front surface of the housing. An inner lid and a drum lid are also provided on the outer tank and the front end face of the drum, respectively.By opening all of the outer lid, the inner lid, and the drum lid, the drum from the near side of the drum type washing machine is opened. The laundry can be taken in and out.

  However, in the conventional drum-type washing machine as described above, since the outer lid is provided on the front surface of the housing, the user must bend when putting laundry in and out of the drum, There was a problem that it was difficult to put laundry in and out.

  In order to solve the above problems, a drum type washing machine having an outer lid provided on an upper surface of a housing has been proposed (for example, see Non-Patent Document 1). In this drum type washing machine, for example, the drum and the outer tub are arranged in the housing with their respective end faces left and right, and the inner lid and the drum lid are provided on the outer tub and the peripheral surface of the drum, respectively. ing. In this drum-type washing machine, by opening the outer lid, the inner lid, and the drum lid, it is possible to put a hand into the drum from an obliquely upper position with respect to the drum, and to put laundry in and out in an easy posture. I have.

  In the above-mentioned drum type washing machine, the opening of the housing which is opened and closed by the outer lid is formed to be long in the front-rear direction so that the laundry can be easily taken in and out. Along with this, the outer lid also needs to have a long shape in the front-rear direction, but in this drum type washing machine, the outer lid is compactly folded behind the opening by making the outer lid foldable. With this, the opening of the housing can be largely opened.

More specifically, the outer lid includes a rear lid that covers the rear side of the opening of the housing, and a front lid that covers the front side. The rear lid has a rear end rotatably mounted on the upper surface of the housing, and the front lid has a rear end rotatably mounted on the front end of the rear lid. The user folds the outer lid so that the front lid and the rear lid stand upward by grasping the grip formed on the front lid and lifting the rear part of the front lid upward and sliding backward. Can be done.

  However, in the above-mentioned drum type washing machine, the opening of the housing is formed long in the front and back (especially, the opening is longer because the opening is provided to be inclined so that the laundry can be easily taken in and out). Therefore, in order to open and close the opening, it is necessary to grasp the grip portion of the front lid and slide it largely forward and backward. Therefore, a configuration that allows the outer lid to be opened and closed more easily has been desired.

  Further, in the above-mentioned drum type washing machine, when the inner lid is opened after the outer lid is folded and opened, the inner lid faces the near side of the folded outer lid, but the inner lid is sufficiently opened. For this purpose, it is necessary to adopt a configuration in which the outer lid is inclined rearward in a folded state. In the case of such a configuration, when the drum-type washing machine is installed such that the rear surface of the housing is along the wall, a tap provided protruding from the wall surface to introduce water into the drum-type washing machine is provided. The outer lid sometimes hit.

  The present invention has been made under such a background, and an object of the present invention is to provide a drum-type washing machine capable of opening and closing a lid (outer lid) more favorably.

In order to achieve the above object, the invention according to claim 1 includes a drum rotatable around a rotation shaft extending in the left and right directions set within a predetermined angle range with respect to the horizontal direction, and has a peripheral surface of the drum. A drum type washing machine in which an opening for taking in and out of laundry is formed,
It accommodates the drum, a housing defining an outer shape of the upper Symbol drum type washing machine, a top cover for covering the upper end face of the housing, which is formed in the lateral center portion of the upper surface of the upper cover, the drum An opening that allows laundry to be taken in and out of the opening of the
Including a slide lid capable of opening and closing the input port by sliding in the front-rear direction along the input port,
On the upper surface of the upper cover, on the right side of the inlet, an operation display panel for performing various displays such as various settings and operation status related to operation is arranged, and on the left side of the inlet, for inputting a detergent. A detergent container is located,
A water supply valve that opens when introducing tap water into the aircraft,
Further comprising a bath water pump driven when introducing bath water into the aircraft,
A space behind the operation display panel and the detergent container in the upper cover, which does not interfere with a slide lid that slides to one side of an area in which the slide lid can slide with respect to a slide direction of the slide lid. Wherein the water supply valve is disposed, and the bath water pump is disposed so as not to interfere with a slide lid that slides to the other side of the slidable area of the slide lid. Machine.

According to the configuration of claim 1, unlike a conventional drum-type washing machine having two lids that can be folded so as to stand up from the upper surface of the housing, for example, a lid is provided in the housing. (Sliding lid) can be accommodated so that the lid does not protrude from the housing. Therefore, even when the drum-type washing machine is installed so that the rear surface of the housing is along the wall, the lid may hit a water tap protruding from the wall surface to introduce water into the drum-type washing machine. And the lid can be opened and closed more favorably.

  Further, since the water supply valve and the bath water pump can be shifted from the slidable area of the slide lid, it is possible to prevent the slide lid from being opened and closed by the water supply valve and the bath water pump. Therefore, the slide lid can be opened and closed favorably.

  In addition, since the water supply valve and the bath water pump are arranged in empty spaces formed on both sides of the area where the slide lid can slide, the water supply valve and the bath water pump are arranged without increasing the size of the drum type washing machine. it can.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

  FIG. 1 is a perspective view showing an external configuration of a drum type washing machine 1 according to one embodiment of the present invention.

  The drum-type washing machine 1 is, for example, partitioned by a casing 2 having a substantially rectangular parallelepiped outer shape. On the front side of the upper surface 2A of the housing 2, for example, an inclined surface 2B inclined so as to become lower toward the front side is formed, and a central portion in the left-right direction from the upper surface 2A of the housing 2 to the inclined surface 2B. Has an opening 4 that can be opened and closed by an outer lid 3.

  On the right side of the opening 4 of the inclined surface 2B, for example, an operation display panel 5 for performing various settings (course settings and the like) relating to the operation of the drum type washing machine 1 and various displays such as an operation status is arranged. . The operation display panel 5 is disposed on the inclined surface 2B so as to face obliquely upward and forward, and a user standing on the near side of the drum-type washing machine 1 faces the operation display panel 5 obliquely downward. Can be looked down vertically. Thereby, the user can easily see the display on the operation display panel 5 and can easily perform the operation.

  Further, on the left side of the opening 4 of the inclined surface 2B, for example, a detergent container 6 for charging a detergent into the machine with the outer lid 3 closed is disposed so as to be able to be pulled out to the near side.

  FIG. 2 is a vertical cross-sectional view of the drum type washing machine 1 and shows a cross-sectional view taken from a vertical plane along the front-rear direction as viewed from the right side. In FIG. 2, the outer lid 3 is omitted.

  Referring to FIG. 2, for example, a substantially cylindrical outer tub 7 whose both end faces are closed is disposed inside housing 2 such that the axis thereof extends left and right (substantially horizontal). The outer tank 7 has, for example, a front central portion on the bottom surface and left and right end portions on the rear side supported by dampers 8 (three in total), respectively (only two are visible in FIG. 2).

  Inside the outer tub 7, a drum 10 for storing laundry therein is arranged. The drum 10 has, for example, a substantially cylindrical shape with both end faces closed, and extends left and right (substantially horizontally) so that its axis is coaxial with the axis of the outer tub 7.

  Rotation shafts 11 extending along the axis of the drum 10 are attached to both end surfaces of the drum 10, respectively. Each rotating shaft 11 is attached to the outer tank 7 so as to be rotatable around an axis. A motor (not shown) is connected to the rotating shaft 11 by, for example, a DD (direct drive) method. When the motor is driven to rotate, the drum 10 connected to the rotating shaft 11 rotates around the axis. It is supposed to.

  The upper surface 2A of the housing 2 is provided with a hose connection port 2C (see FIG. 1) for connecting a water supply hose to an external water supply facility (such as a water tap), for example. At the time of washing, tap water (hereinafter simply referred to as “water”) supplied through a water supply hose enters the machine through the hose connection port 2C and is supplied into the outer tub 7 through the water supply pipe 15. It is supposed to be.

  A number of water holes (not shown) are formed on the peripheral surface of the drum 10, and water supplied to the outer tank 7 flows into the drum 10 through these water holes. It has become. Also, on the inner peripheral surface of the drum 10, one protruding baffle 10 </ b> B for lifting the laundry in the drum 10 is provided at every predetermined equal angle in the circumferential direction (for example, at every 120 °) (three in total). ), Each extending in the left-right direction. In the washing process, the operation (tumbling) of rotating the drum 10 to lift the laundry in the drum 10 by the baffle 10B and dropping the laundry naturally from a certain height is repeated, so that the laundry is stored in the outer tub 7. The pond is smashed on the surface of the water stored in the pond so that the pouring is achieved.

  When the washing step is completed, a rinsing step for removing detergent components contained in the laundry is performed, and thereafter, the process proceeds to a dehydration step. In the dehydration step, the drum 10 is rotated at a high speed (for example, 300 to 1000 rpm), water contained in the laundry is squeezed out by centrifugal force, and the water that has come out of the laundry passes through the water holes and the outer tub 7. Splashes to the side.

  An opening 22 for taking in and out of laundry is formed on the peripheral surface of the drum 10. An opening 23 is formed on a peripheral surface of the outer tub 7 at a position facing the opening 4 of the housing 2. The opening 23 of the outer tub 7 and the opening 22 of the drum 10 can be opened and closed by, for example, an inner lid 24 and a drum lid 25 that can rotate outward (upward in FIG. 2), respectively. The laundry can be taken in and out of the drum 4 with all of the inner lid 24 and the drum lid 25 opened.

  The inner lid 24 is, for example, a plate-like member having a substantially arc-shaped cross section, and a rear end thereof is rotatably attached to the outer tub 7. When the inner lid 24 is closed, the distal end of the inner lid 24 is engaged with the outer tub 7 so that the opening 23 is closed in a watertight manner.

  To open the inner lid 24, the outer lid 3 must first be opened. When the outer lid 3 is opened, a space for opening the inner lid 24 is secured above the outer tub 7, and in this state, the inner lid 24 is pivoted upward by grasping and lifting the tip of the inner lid 24. Then, the opening 23 of the outer tank 7 can be opened.

  The drum lid 25 includes, for example, a rear lid 25A and a front lid 25B. The rear end of the rear cover 25 </ b> A is rotatably attached to the peripheral surface of the drum 10. On the other hand, the front end of the front lid 25B is rotatably attached to the peripheral surface of the drum 10. The rear end of the rear lid 25A and the front end of the front lid 25B are connected by, for example, a bar-shaped connecting member 26. When one of the rear lid 25A and the front lid 25B is rotated, the other is rotated in conjunction with the rotation. It works. The rear lid 25A and the front lid 25B are urged toward the opening direction (upward) by an urging member (not shown) such as a spring, for example. The connecting member 26 is covered by, for example, a cover 27.

  At the rear end of the front lid 25B, a claw 25C is formed so as to protrude. At the front end of the rear lid 25A, an engagement recess 25D corresponding to the claw 25C of the front lid 25B is formed. With such a configuration, when the rear lid 25A and the front lid 25B are closed, the claw 25C is hooked on the engagement recess 25D, and the closed state is maintained.

  In order to open the drum lid 25, the outer lid 3 and the inner lid 24 must be opened, and a space for opening the drum lid 25 must be secured above the drum 10. In this state, by pushing down the front lid 25B of the drum lid 25, the engagement between the claw portion 25C and the engagement concave portion 25D can be released.

  The rear lid 25A and the front lid 25B, which are disengaged from each other, are opened to the state shown in FIG. 2 by the urging force of the urging members applied thereto, and the opening 22 of the drum 10 is largely opened. In this embodiment, the front lid 25B of the drum lid 25 is pushed down in response to opening the inner lid 24, so that when the inner lid 24 is opened, the drum lid 25 is also opened at the same time. Has become.

  When closing the drum lid 25, only the rear lid 25A is pivoted downward, and the front lid 25B connected via the coupling member 26 is also pivoted downward together with the claw 25C and the engaging recess 25D. Can be engaged.

  FIGS. 3 and 4 are vertical cross-sectional views for explaining the configuration of the outer lid 31 according to the first embodiment, and are cross-sectional views taken along a vertical plane along the front-rear direction as viewed from the right side. Is shown. FIG. 3 shows a state in which the outer lid 31 is closed, and FIG. 4 shows a state in which the outer lid 31 is opened.

  Referring to FIGS. 3 and 4, outer cover 31 according to this embodiment connects, for example, a plurality of bar-shaped members 31 </ b> A extending in the left-right direction with flexible members so as to be parallel to each other. It has the same configuration as a so-called bath lid.

  The outer lid 31 is slidable so that the left and right sides are along the side edge of the opening 4 of the housing 2. By configuring the outer lid 31 as described above, the outer lid 31 can be bent between the respective bar-shaped members 31A, and the outer lid 31 is opened along a side edge of the opening 4 in a bent state. 4 is covered.

  A guide member 31 </ b> D extends in the front-rear direction above the left and right side edges of the opening 4. When the outer cover 31 is slid along the side edge of the opening 4, the left and right ends of the outer cover 31 are moved. The upper surface of the portion follows the lower surface of the guide member 31D. Thereby, the outer lid 31 can be pressed by the guide member 31D so as not to float from the side edge of the opening 4.

  As shown in FIG. 3, when the outer cover 31 covers the opening 4 from the rear end to the front end, a force acts on the outer cover 31 in the closing direction by the gravity of the outer cover 31. In the state shown in FIG. 3, the projection 31B formed at the rear end of the outer lid 31 abuts against the stopper 2D of the housing 2, so that the outer lid 31 does not slide further forward. With such a configuration, when the outer lid 31 is closed to the state shown in FIG. 3, the outer lid 31 is maintained in a closed state.

  From the state shown in FIG. 3, when the gripper 31 </ b> C formed at the front end of the outer lid 31 is gripped and the outer lid 31 is slid rearward along the side edge of the opening 4, the outer lid 31 is accordingly moved. Are housed in the housing 2 from the rear side. At this time, the outer lid 31 is accommodated in the rear side in the housing 2 in a state of hanging vertically. However, the outer lid 31 may be wound and housed in a scroll shape.

  When the outer lid 31 is opened to a predetermined position, the force acting on the outer lid 31 due to the gravity of the outer lid 31 switches to the force in the opening direction. Therefore, when the user opens the outer cover 31 to the predetermined position, the outer cover 31 is automatically opened thereafter, and the opening 4 of the housing 2 is opened as shown in FIG. At this time, the grip portion 31C of the outer lid 31 comes into contact with the rear edge of the opening 4 so that the outer lid 31 does not slide further backward. With such a configuration, when the outer lid 31 is opened to the state shown in FIG. 4, the outer lid 31 is maintained in the open state.

  When the outer lid 31 is closed, the force acting on the outer lid 31 by the gravity of the outer lid 31 is closed when the outer lid 31 is closed to the predetermined position by grasping the grip portion 31C and sliding it toward the user. Then, the outer lid 31 is automatically closed thereafter.

  In this embodiment, since the direction of the force acting on the outer lid 31 due to the gravity of the outer lid 31 is switched at the predetermined position, when the outer lid 31 is opened, from the closed state to the predetermined position. Only by opening, the outer lid 31 is automatically opened thereafter. When the outer lid 31 is closed, it only needs to be closed from the opened state to the above-mentioned predetermined position, and thereafter, the outer lid 31 is automatically closed. It is supposed to be. Therefore, the outer lid 31 can be more easily opened and closed.

  Further, when the outer lid 31 is opened, the outer lid 31 is accommodated in the housing 2 so that the drum-type washing machine 1 is installed such that the rear surface of the housing 2 is along the wall. Even when this is done, the outer lid 31 does not hit the faucet provided to protrude from the wall surface to introduce water into the drum type washing machine 1.

  As described above, according to the configuration of the outer lid 31 according to this embodiment, the opening and closing of the outer lid 31 can be performed more favorably.

  In the above embodiment, the configuration in which the force acts on the outer lid 31 in the closing direction or the opening direction by the gravity of the outer lid 31 has been described, but the urging means ( A spring or the like) may be provided.

  As a configuration in which a force always acts on the outer lid 31 in a direction in which the outer lid 31 is opened, a means (a claw or the like) for maintaining the outer lid 31 in a closed state may be separately provided. Further, a means (a claw or the like) for maintaining the outer lid 31 in an open state may be separately provided as a configuration in which a force always acts on the outer lid 31 in the closing direction.

  The outer lid 31 may have a configuration in which the opening 4 is opened by being slid to the near side. In this case, the outer lid 31 may be accommodated on the front side in the housing 2.

  The outer lid 31 is not limited to a bath lid, as long as its side is slidable along the side edge of the opening 4. May be used.

  Further, the outer lid 31 is not limited to the configuration that is opened and closed in the front-rear direction, and may be, for example, a configuration that is opened and closed in the left-right direction.

  FIGS. 5 and 6 are vertical cross-sectional views for explaining the configuration of the outer lid 32 according to the second embodiment, and are cross-sectional views taken from a vertical plane along the front-rear direction and viewed from the right side. Is shown. FIG. 5 shows a state where the outer lid 32 is closed, and FIG. 6 shows a state where the outer lid 32 is opened.

  5 and 6, the outer lid 32 according to this embodiment includes, for example, a front lid 321 that covers the front side of the opening 4 and a rear lid 322 that covers the rear side. The rear end of the rear lid 322 is rotatably attached to the upper surface 2A of the housing 2 via a rotating shaft 323 extending left and right. The rear end of the front lid 321 is rotatably attached to the front end of the rear lid 322 via a rotating shaft 324 extending left and right. When the outer lid 32 is opened, the front lid 321 and the rear lid 322 are folded so as to rise upward from the upper surface 2A, and the opening 4 is opened (see FIG. 6).

  The rotating shaft 323 is covered with a torsion coil spring 325. One end of the torsion coil spring 325 is fixed to the upper surface of the housing 2, and the other end is in contact with the lower surface of the rear cover 322. When the outer lid 32 is closed as shown in FIG. 5, an urging force acts in a direction in which the rear lid 322 is lifted (that is, a direction in which the outer lid 32 is opened) by the action of the torsion coil spring 325. I have. For example, only one torsion coil spring 325 may be provided at the center or one end of the rotating shaft 323, or two or more torsion coil springs 325 may be provided.

  At the center of the front end of the front lid 321, for example, a claw 326 for engaging with the upper end of the front surface of the housing 2 to maintain the outer lid 32 in a closed state is formed. An engaging hole 327 is formed at the upper end of the front surface of the housing 2 at a position facing the claw portion 326 when the outer lid 32 is closed, and when the outer lid 32 is closed, the claw of the front lid 321 is formed. The portion 326 engages with the engagement hole 327 (see FIG. 5). With such a configuration, when the outer lid 32 is closed, the outer lid 32 can be maintained in a closed state against the urging force of the torsion coil spring 325.

  An operation member 328 for a user to perform a push operation from the near side is attached to the upper end of the front surface of the housing 2 at a position facing the engagement hole 327. The operation member 328 is rotatably attached to the front surface of the housing 2 and is urged toward the front surface of the housing 2 (clockwise) by an appropriate force.

  The operation member 328 is provided with a projection 328A that can penetrate the engagement hole 327. That is, when the outer lid 32 is closed, the operation member 328 is pushed up counterclockwise against the clockwise urging force by the claw portion 326 engaged with the engagement hole 327 (see FIG. 5). When the user presses the operation member 328, the projection 328A penetrates the engagement hole 327 and presses the claw 326, and the claw 326 engaged with the engagement hole 327 is disengaged from the engagement hole 327. They are being evacuated. As described above, since the outer lid 32 is urged in the opening direction, when the claw portion 326 is retracted from the engagement hole 327, the outer lid 32 is automatically folded, as shown in FIG. Then, the opening 4 is opened.

  When closing the outer lid 32, the user grips the grip portion 321 </ b> A formed on the front lid 321, pulls the front lid 321 toward the front side against the urging force of the torsion coil spring 325, and The claw portion 326 is engaged with the engagement hole 327.

  In this embodiment, the outer lid 32 can be opened with one touch only by pushing the operation member 328. Therefore, when the outer lid 32 is opened, the outer lid 32 is enlarged from the front end to the rear end of the opening 4. No need to slide. Therefore, the outer lid 32 can be more easily (satisfactorily) opened and closed.

  A damper (for example, an oil damper attached to the rotating shaft 323) for preventing the outer lid 32 (the rear lid 322) from opening vigorously may be provided. With such a configuration, it is possible to prevent the outer lid 32 from being vigorously opened and damaged, and the opening and closing of the outer lid 32 can be performed more favorably.

  7 to 9 are longitudinal cross-sectional views for describing the configuration of the outer lid 33 according to the third embodiment, and are views of the cross section taken along a vertical plane along the front-rear direction as viewed from the right side. Is shown. 7 shows a state in which the outer lid 33 is closed, FIG. 8 shows a state in which the outer lid 33 is partially opened, and FIG. 9 shows a state in which the outer lid 33 is completely opened.

  7 to 9, the outer lid 33 according to this embodiment includes, for example, a front lid 331 that covers the front side of the opening 4 and a rear lid 332 that covers the rear side. The rear end of the rear cover 332 is rotatably attached to the upper surface 2A of the housing 2 via a rotation shaft 333 extending left and right. The front end of the front lid 331 is rotatably attached to the front end of the rear lid 332 via a rotation shaft 334 extending left and right. When the outer lid 33 is opened, the front lid 331 and the rear lid 332 are folded so as to rise upward from the upper surface 2A, and the opening 4 is opened (see FIG. 9).

  The rear end of the side surface of the front cover 331 and the front end of the side surface of the rear cover 332 are connected to each other by a long connecting member 335. An end of the connecting member 335 on the front lid 331 side is rotatably attached to a side surface of the front lid 331 via a rotation shaft 335A. On the other hand, a projection 335B is formed at the end of the connecting member 335 on the rear lid 332 side, and the projection 335B penetrates an elongated hole 332A formed along the side surface of the rear lid 332. In addition, the end of the connection member 335 on the rear lid 332 side and the rear side of the center of the side surface of the rear lid 332 are connected via a tension coil spring 336. Such a structure using the connecting member 335 and the extension coil spring 336 may be provided only on one side of the outer lid 33 or may be provided on both sides.

  As shown in FIG. 7, when the outer lid 33 is closed, the connecting member 335 extends to the side of the rotating shaft 334, and acts on the front lid 331 via the connecting member 335 by the action of the tension coil spring 336. The force acts toward the rotation shaft 334 as shown by an arrow in FIG. Therefore, in a state where the outer lid 33 is closed, the urging force of the extension coil spring 336 on the front lid 331 hardly acts in the direction in which the front lid 331 is rotated, so that the outer lid 33 is maintained in the closed state. Will be done. At this time, the protrusion 335B of the connecting member 335 is in a state of contacting the front end of the elongated hole 332A.

  When the user grips the grip portion 331A formed on the front lid 331 from the state of FIG. 7 and slides it rearward while lifting the rear part of the front lid 331 upward, the protrusion 335B of the connecting member 335 is moved along the elongated hole 332A. To slide backwards. As a result, the extending position of the connecting member 335 moves below the rotation shaft 334, and the urging force acting on the front lid 331 via the connecting member 335 by the action of the extension coil spring 336 is indicated by an arrow in FIG. Thus, it acts in the direction in which the front lid 331 is rotated downward (in the direction in which it is opened).

  Therefore, when the outer lid 33 is opened from a state where the outer lid 33 is closed as shown in FIG. 7 to a predetermined position, the outer lid 33 is thereafter opened until the opening 4 of the housing 2 is opened as shown in FIG. A force acts in a direction in which the lid 33 is opened. In the state shown in FIG. 9, the projection 335B of the connecting member 335 is in contact with the rear end edge of the long hole 332A, so that the outer lid 33 cannot be further opened. In this state, the urging force of the tension coil spring 336 acts in the direction to open the outer lid 33, as indicated by the arrow in the figure, so that the outer lid 33 is maintained in this state (open state).

  When closing the outer lid 33, the user grips the grip portion 331 </ b> A formed on the front lid 331 and pulls the front lid 331 against the urging force of the extension coil spring 336 to the front side until the state shown in FIG. 7 is reached. It will be.

  In this embodiment, when the outer lid 33 is opened from the closed state to the above-described predetermined position, the urging force of the tension coil spring 336 acts in a direction to open the outer lid 33. That is, if the urging force of the tension coil spring 336 is set to be strong, the outer lid 33 can be automatically opened after the outer lid 33 is opened to the predetermined position, while the urging force of the tension coil spring 336 can be reduced. If it is set to be weaker, the outer lid 33 can be opened with a smaller force after opening the outer lid 33 to the predetermined position. Therefore, the outer lid 33 can be more easily opened and closed.

  When the outer lid 33 is opened, the protrusion 335B of the connecting member 335 contacts the rear end edge of the elongated hole 332A, and the outer lid 33 is not opened any more. If properly adjusted, even when the drum-type washing machine 1 is installed such that the rear surface of the housing 2 is along the wall, the drum-type washing machine 1 is provided to protrude from the wall surface to introduce water into the drum-type washing machine 1. The outer lid 33 does not hit the faucet.

  As described above, according to the configuration of the outer lid 33 according to this embodiment, the opening and closing of the outer lid 33 can be performed more favorably.

  A damper (for example, an oil damper attached to the rotating shaft 333) for preventing the outer lid 33 (the rear lid 332) from opening vigorously may be provided. With such a configuration, it is possible to prevent the outer lid 33 from being vigorously opened and damaged, and to be able to open and close the outer lid 33 more favorably.

  In the above-described embodiment, a configuration is described in which the urging force of the tension coil spring 336 hardly acts in the direction in which the front cover 331 is rotated when the outer cover 33 is closed. As a configuration in which the urging force acts in the opening direction, a means (a claw or the like) for maintaining the outer lid 33 in a closed state may be separately provided.

  FIGS. 10 to 12 are vertical cross-sectional views for explaining the configuration of the outer lid 34 according to the fourth embodiment, and are cross-sectional views taken along a vertical plane along the front-rear direction and viewed from the right side. Is shown. 10 shows a state in which the outer lid 34 is closed, FIG. 11 shows a state in which the outer lid 34 is partially opened, and FIG. 12 shows a state in which the outer lid 34 is completely opened.

  Referring to FIGS. 10 to 12, outer cover 34 according to this embodiment includes, for example, a front cover 341 that covers the front side of opening 4 and a rear cover 342 that covers the rear side. The rear end of the rear lid 342 is rotatably attached to the upper surface 2A of the housing 2 via a rotating shaft 343 extending left and right. The rear end of the front lid 341 is rotatably attached to the front end of the rear lid 342 via a rotation shaft 344 extending in the left and right directions. When the outer lid 34 is open, the front lid 341 and the rear lid 342 are folded so as to rise upward from the upper surface 2A, and the opening 4 is opened (see FIG. 12).

  On both side edges of the opening 4, side edge plates 4 </ b> A projecting inward (left and right directions) of the opening 4 are formed. The front end of the side edge plate 4A is bent downward (see FIGS. 11 and 12).

  A guide member 345 movable along the side edge plate 4A is attached to the front end of the side surface of the front lid 341 so as to be rotatable via a rotation shaft 346. The guide member 345 has a base 345A one end of which is rotatably attached to the rotation shaft 346 and a direction (lateral direction) orthogonal to the direction in which the base 345 extends from the other end of the base 345. It has a substantially L-shape including a contact portion 345B that is formed to protrude and abuts on the lower surface (inner surface) of the side edge plate 4A. In this manner, a configuration in which the front end of the front lid 341 is guided along the side edge plate 4A (that is, a configuration in which both the front end and the rear end of the outer lid 34 are engaged with the housing 2) ), Twisting when the outer lid 34 is opened and closed can be prevented, and the opening and closing of the outer lid 34 can be made smoother. Therefore, the opening and closing of the outer lid 34 can be performed more favorably.

  The rotating shaft 346 is covered with a torsion coil spring 347. One end of the torsion coil spring 347 contacts the lower surface of the front cover 341, and the other end contacts the rear surface of the base 345 </ b> A of the guide member 345. By the function of the torsion coil spring 347, an urging force acts on the guide member 345 in a direction for rotating the guide member 345 toward the near side (clockwise). Such a structure using the guide member 345 or the torsion coil spring 347 may be provided only on one side of the outer lid 34 or may be provided on both sides.

  As shown in FIG. 10, when the outer lid 34 is closed, the guide member 345 is located at the front end (the part bent downward) of the side edge plate 4A. In this state, the guide member 345 is rotated rearward (counterclockwise) against the urging force of the torsion coil spring 347, and the guide member 345 (the contact member) is actuated by the action of the torsion coil spring 347. The urging force acting on the side edge plate 4A via the contact portion 345B) acts in the direction in which the front cover 341 extends as indicated by an arrow in FIG. Therefore, when the outer lid 34 is closed, the reaction force acting on the rotating shaft 346 by the urging force of the torsion coil spring 347 becomes a force in the direction opposite to the above-mentioned arrow, and moves in the direction of rotating the front lid 341. Since the outer lid 34 hardly acts, the outer lid 34 is maintained in a closed state.

  From the state of FIG. 10, when the user grips the grip portion 341 </ b> A formed on the front lid 341 and slides backward while lifting the rear part of the front lid 341 upward, the guide member is biased by the biasing force of the torsion coil spring 347. 345 rotates clockwise, and the contact portion 345B moves upward along the side edge plate 4A. Then, the side edge plate 4A is sandwiched between the contact portion 345B of the guide member 345 and the lower surface of the side edge of the front lid 341 (see FIG. 11). Accordingly, the front lid 341 that is to be displaced to the near side (close direction) by gravity is moved between the lower surface of the side edge plate 4A and the contact portion 345B, and between the upper surface of the side edge plate 4A and the lower surface of the front lid 341. It can be stopped by the generated frictional force. Therefore, when the hand is released from the grip portion 341A during opening and closing, the outer lid 34 can be prevented from automatically closing due to gravity, and the outer lid 34 is less likely to be damaged.

  When the outer lid 34 is further opened and the opening 4 of the housing 2 is completely opened as shown in FIG. 12, the contact portion 345B of the guide member 345 contacts the rear edge of the opening 4, The outer lid 34 is not opened any more.

  When closing the outer lid 34, the user grips the grip portion 341A formed on the front lid 341 and pulls the front lid 341 toward the user until the state shown in FIG. 10 is reached.

  In this embodiment, when the outer lid 34 is completely opened, the contact portion 345B of the guide member 345 comes into contact with the rear end edge of the opening 4 and the outer lid 34 is not opened further. If the position where the outer lid 34 is completely opened is appropriately adjusted, water is introduced into the drum-type washing machine 1 even when the drum-type washing machine 1 is installed so that the rear surface of the housing 2 is along the wall. Therefore, the outer lid 33 does not hit the faucet provided protruding from the wall surface. Therefore, the opening and closing of the outer lid 34 can be performed more favorably.

  An urging means (spring or the like) for applying a force in a direction to open the outer lid 34 may be provided. In this case, a means (a claw or the like) for maintaining the outer lid 34 in a closed state may be separately provided as a configuration in which a force always acts on the outer lid 34 in the opening direction.

  FIG. 13 and FIG. 14 are longitudinal sectional views for explaining the configuration of the outer lid 35 according to the fifth embodiment, and are cross-sectional views cut from a vertical plane along the front-rear direction as viewed from the right side. Is shown. FIG. 13 shows a state in which the outer lid 35 is closed, and FIG. 14 shows a state in which the outer lid 35 is opened.

  13 and 14, the outer lid 35 according to this embodiment includes, for example, a front lid 351 that covers the front side of the opening 4 and a rear lid 352 that covers the rear side. The front cover 351 covers a portion of the opening 4 formed on the inclined surface 2B of the housing 2, and the rear cover 352 covers a portion of the opening 4 formed on the upper surface 2A of the housing 2. ing. That is, the front side of the boundary between the upper surface 2A and the inclined surface 2B of the housing 2 in the opening 4 is covered by the front lid 351, and the rear side of the boundary is covered by the rear lid 352. The front lid 351 and the rear lid 352 are each configured by connecting a plurality of rod-shaped members 351A and 352A extending in the left-right direction with flexible members so as to be parallel to each other, and a first embodiment.

With the outer lid 35 having the above-described configuration, the outer lid 35 can be bent between the rod-shaped members 351A and 352B, and the outer lid 35 is bent along the side edge of the opening 4. To cover the opening 4.

  A guide member 353 extends in the front-rear direction above the left and right side edges of the opening 4. When the front cover 351 and the rear cover 352 are slid along the side edges of the opening 4, the front cover 351 and the The upper surface of the left and right ends of the rear cover 352 is configured to be along the lower surface of the guide member 353. Thus, the front cover 351 and the rear cover 352 can be pressed by the guide member 353 so as not to float from the side edge of the opening 4.

  The housing 2 includes an endless wire 354 that extends from the near side to the rear side in the housing 2 and a plurality of pulleys 355 around which the wire 354 is wound. The wire 354 and the pulley 355 are an interlocking mechanism for interlocking the opening and closing of the front lid 351 and the rear lid 352. The rear end of the front lid 351 and the rear end of the rear lid 352 are each connected by a connecting member 356. 354.

  As shown in FIG. 13, when the outer cover 35 covers the opening 4 from the rear end to the front end, the projection 352B formed at the rear end of the rear lid 352 contacts the stopper 2D of the housing 2, and The lid 352 does not slide further forward. From the state shown in FIG. 13, when the gripper 351B formed at the rear end of the front lid 352 is gripped and the front lid 351 is slid forward along the side edge of the opening 4, the interlocking mechanism (the wire 354 and the By the action of the pulley 355), the rear lid 352 is housed in the housing 2 from the rear side (see FIG. 14).

  At this time, the rear lid 352 is accommodated in the rear side in the housing 2 in a state of hanging vertically. On the other hand, the front lid 351 hangs vertically along the front side of the housing 2. However, when the outer lid 35 is opened, the front lid 351 and the rear lid 352 may be wound in a scroll shape. Further, the front lid 351 may be accommodated on the near side in the housing 2.

  When closing the outer lid 35, the user grips the grip part 351B and slides the front lid 351 backward. Thereby, the rear cover 352 can also be slid toward the front side in conjunction with it, and the opening 4 can be closed as shown in FIG.

  In the above embodiment, the opening 4 can be opened and closed simply by sliding the front cover 351 by about half the length of the opening 4 in the front-rear direction. it can.

  Further, when the outer lid 35 is opened, the rear lid 352 is housed in the housing 2, so that the drum type washing machine 1 is installed so that the rear surface of the housing 2 is along the wall. Even at this time, the outer lid 35 does not hit the faucet provided to protrude from the wall surface to introduce water into the drum type washing machine 1.

  As described above, according to the configuration of the outer lid 35 according to this embodiment, the opening and closing of the outer lid 35 can be performed more favorably.

  An urging means (spring or the like) for applying a force to the outer lid 35 in the opening / closing direction may be provided. In this case, a means (a claw or the like) for maintaining the outer lid 35 in a closed state may be separately provided so that a force always acts on the outer lid 35 in the opening direction. Further, as a configuration in which a force always acts on the outer lid 35 in the closing direction, a means (a claw or the like) for maintaining the outer lid 35 in an open state may be separately provided.

  The grip 351B may be provided at the front end of the rear cover 352, not at the rear end of the front cover 351. Further, if the grip 351B is provided on both the rear end of the front lid 351 and the front end of the rear lid 352, the outer lid can be slid by sliding either the front lid 351 or the rear lid 352. 35 can be opened and closed, which is convenient.

  The front lid 351 and the rear lid 352 are not limited to a bath lid as long as their sides are slidable along the side edge of the opening 4 and have flexibility, for example. It may be a sheet-like member.

  The rear lid 352 does not have a configuration in which the side edge slides along the side edge of the opening 4, but includes, for example, two lids that are rotatably attached to each other, and is located above the upper surface 2 </ b> A of the housing 2. It may be configured so that it can be folded upright.

  The outer lid 35 is not limited to a configuration that is opened and closed in the front-rear direction, and may be a configuration that is opened and closed in the left-right direction, for example.

  FIGS. 15 and 16 are plan views for describing the configuration of the outer lid 36 according to the sixth embodiment. FIG. 15 shows a state where the outer lid 36 is closed, and FIG. 16 shows a state where the outer lid 36 is opened.

  15 and 16, the outer lid 36 according to this embodiment includes, for example, a front lid 361 that covers the front side of the opening 4 and a rear lid 362 that covers the rear side. The left end of the rear lid 362 is rotatably attached to the upper surface 2 </ b> A of the housing 2 via a rotating shaft 363 that extends forward and backward. The front end of the front cover 361 is rotatably attached to the front end of the rear cover 362 via a rotation shaft 364 (see FIG. 16). Thus, the outer lid 36 is rotatable in a direction (lateral direction) crossing a direction in which the front lid 361 and the rear lid 362 are folded (front-back direction).

  As shown in FIG. 15, from the state where the outer lid 36 is closed, the user grips a grip (not shown) formed on the front lid 361, and the front lid 361 and the rear lid 362 around the rotation shaft 363. The front cover 361 and the rear cover 362 are rotated to the left side of the opening 4 by rotating the front cover 361 backward with respect to the rear It is folded so as to stand upward from the upper surface 2A, and the opening 4 is opened (see FIG. 16).

  In this embodiment, since the outer lid 36 can be folded to the left of the opening 4, when the outer lid 36 is opened and closed, the outer lid 36 is largely slid back and forth between the front end and the rear end of the opening 4. The outer lid 36 can be more easily opened and closed as compared with.

  Further, since the outer lid 36 can be folded to the left of the opening 4, even when the drum-type washing machine 1 is installed so that the rear surface of the housing 2 is along the wall, water is supplied into the drum-type washing machine 1. The outer lid 36 does not hit the faucet provided to protrude from the wall surface for introduction.

As described above, according to the configuration of the outer lid 36 according to this embodiment, the outer lid 36 can be opened and closed more favorably.

  A biasing means (spring or the like) for applying a force in a direction to open the rear cover 362 may be provided. In this case, a means (a claw or the like) for maintaining the outer lid 36 in a closed state may be separately provided as a configuration in which a force always acts on the rear lid 362 in the opening direction.

  The front lid 361 may be folded on the left side of the rear lid 362 instead of being folded on the right side of the rear lid 362.

  Further, the configuration is not limited to the configuration in which the front lid 361 and the rear lid 362 are folded to the left of the opening 4, and may be configured to be folded to the right of the opening 4, or may be folded diagonally rearward of the opening 4. Configuration may be used.

  The outer lid 36 is not limited to one composed of two lids (the front lid 361 and the rear lid 362), and may be composed of three or more lids.

  17 and 18 are vertical cross-sectional views for explaining the configuration of the outer lid 37 according to the seventh embodiment, and are cross-sectional views taken from a vertical plane along the front-rear direction and viewed from the right side. Is shown. FIG. 17 shows a state where the inner lid 24 and the outer lid 37 are closed, and FIG. 18 shows a state where the inner lid 24 and the outer lid 37 are opened.

  17 and 18, outer cover 37 according to this embodiment covers, for example, front cover 371 that covers the front end of opening 4 and the rear side of front cover 371 (most of opening 4). And a rear lid 372. The front lid 371 has a relatively short dimension in the front-rear direction (depth direction), and the rear lid 372 has a relatively long dimension in the front-rear direction.

  The rear end of the rear lid 372 is rotatably attached to the upper surface 2A of the housing 2 via a rotating shaft 373 extending left and right. The rear end of the front lid 371 is rotatably attached to the front end of the rear lid 372 via a rotation shaft 374 extending left and right. When the outer lid 37 is opened, the rear lid 372 rises upward from the upper surface 2A, and the front lid 371 is folded from the front end piece of the rear lid 372 to a lower middle part, so that the opening 4 is opened. (See FIG. 18). In this state, the center of gravity of the outer lid 37 is shifted rearward as compared with the conventional configuration in which the front lid is folded to face the entire front surface of the rear lid. Therefore, even if the amount of rotation of the rear lid 372 (the amount of tilting backward) is small, the outer lid 37 can be favorably held in a folded state.

  The rear side of the side surface of the rear lid 372 is connected to the side plate 2E of the housing 2 by a long connecting member 375. An end on the rear lid 372 side of the connecting member 375 is rotatably attached to a side surface of the rear lid 372 via a rotation shaft 375A. On the other hand, a protrusion 375B is formed at an end of the connecting member 375 on the side plate 2E side, and the protrusion 375B penetrates an elongated hole 375C formed in the side plate 2E of the housing 2. Such a structure using the connecting member 375 may be provided only on one side surface of the outer lid 37 or may be provided on both side surfaces.

  As shown in FIG. 17, when the outer lid 37 is closed, the protrusion 375B of the connecting member 375 is in contact with the front edge of the long hole 375C. From this state, when the user grips the grip portion 371A formed on the front cover 371 and slides the front cover 371 upward while sliding it upward, the protrusion 375B of the connecting member 375 moves rearward along the long hole 375C. Slide. When the outer lid 37 is open as shown in FIG. 18, the projection 375B of the connecting member 375 abuts against the rear end edge of the long hole 375C, so that the outer lid 37 cannot be further opened.

  When closing the outer lid 37, the user grips the grip portion 371A formed on the front lid 371 and pulls the front lid 371 toward the user until the state shown in FIG. 17 is reached.

  In the above embodiment, since the front lid 371 has a relatively short shape with respect to the rear lid 372, the inner lid 24 is opened after the outer lid 37 is opened as shown in FIG. Is opposed to the front side of the rear lid 372, and the front lid 371 is located above the inner lid 24. That is, when the inner lid 24 is opened with the outer lid 37 folded and opened, the front end (upper end) of the inner lid 24 does not overlap the folded front lid 371. Accordingly, compared to a configuration in which the inner lid 24 faces the front side of the folded front lid 372, the inner lid 24 can be sufficiently opened even if the amount of rotation of the rear lid 372 to the rear side is small. it can. Therefore, even when the drum-type washing machine 1 is installed such that the rear surface of the housing 2 is along the wall, the drum-type washing machine 1 is attached to a water tap protruding from the wall to introduce water into the drum-type washing machine 1. Since the cover 37 can be prevented from hitting, the opening and closing of the outer cover 37 can be performed more favorably.

  An urging means (spring or the like) for applying a force in a direction to open the outer lid 37 may be provided. In this case, a means (a claw or the like) for maintaining the outer lid 37 in a closed state may be separately provided so that the force always acts on the outer lid 37 in the opening direction.

  The outer lid 37 is not limited to the one composed of two lids (the front lid 371 and the rear lid 372), and may be composed of three or more lids.

  FIG. 19 is a perspective view showing an external configuration of a drum type washing machine 100 according to the eighth embodiment of the present invention.

  The drum-type washing machine 100 is, for example, partitioned by a housing 200 having a substantially rectangular parallelepiped shape. An upper end surface of the housing 200 is an opening, and an upper cover 210 is covered from above so as to cover the upper end surface of the housing 200. An opening 4 that can be opened and closed by the outer lid 38 is formed on the upper surface of the upper cover 210 from the front end to the rear end of the central portion in the left-right direction. The outer lid 38 is slidable in the front-rear direction such that left and right sides thereof are along left and right side edges of the opening 4 of the housing 200.

  At the front end of the outer lid 38, for example, a resin gripping member 38A for gripping by a user when the outer lid 38 is slid is attached. The gripping member 38A has a longitudinal shape whose length in the left-right direction substantially coincides with the length (width) in the left-right direction of the outer lid 38, and has a protruding grip for the user to grip at the center thereof. A portion 38B is formed.

  A rear cover 220 extending in the left-right direction is covered from above at a corner at the rear end of the upper cover 210. When the rear cover 220 is attached, the upper surface of the rear cover 220 is flush with the upper surface of the upper cover 210. At the left end of the upper surface of the rear cover 220, for example, a tap water inlet 2F for introducing tap water into the drum type washing machine 100 from an external tap facility (such as a tap) is provided. On the other hand, at the right end of the upper surface of the rear cover 220, for example, a bath water inlet 2G for introducing bath water into the drum type washing machine 100 is provided. At the time of washing, washing is performed using tap water introduced into the machine from the tap water inlet 2F or bath water introduced into the machine from the bath water inlet 2G.

  On the right front side of the upper surface of the upper cover 210 (on the right side of the opening 4), as with the drum-type washing machine 1 according to the first embodiment, various settings related to the operation of the drum-type washing machine 100 (course settings and the like), An operation display panel 5 for performing various displays such as driving conditions is provided. On the left front side of the upper surface of the upper cover 210 (left side of the opening 4), for example, a detergent container 6 for charging a detergent into the machine is arranged so as to be able to be pulled out to the front side.

  FIG. 20 is a partially enlarged side view for describing the configuration of the outer lid 38.

  The outer lid 38 has a configuration similar to the outer lid 31 of the drum-type washing machine 1 according to the first embodiment, and connects a plurality of bar-shaped members 381 extending in the left-right direction so as to be parallel to each other. It consists of. In each rod-shaped member 381, for example, two through holes 381A extending in the longitudinal direction are formed.

  On one long side of each bar-shaped member 381, a hook portion 381B that is bent downward from the upper portion is formed. A hook receiving portion 381C is formed on the other long side of each rod-shaped member 381 so as to be curved in a substantially arc shape from a lower portion thereof upward. The tip portion of the hook portion 381B is formed in a substantially circular shape in a side view, and the tip portion of the hook portion 381B is fitted into the hook receiving portion 381 curved in a substantially arc shape, so that the adjacent rod-shaped member is formed. 381 are connected to each other. The hook portion 381B and the hook receiving portion 381C are rotatably fitted to each other, so that the adjacent bar-shaped members 381 can rotate relative to each other. With such a configuration, the outer lid 38 can have a configuration similar to a bath lid that can be bent between the rod-shaped members 381.

  The hook portion 381B of the outer lid 38 is connected to the hook receiving portion 381C in a state where two adjacent bar members 381 are slightly bent, and the hook portion 381B side is connected in the direction of the connected bar member 381 (arrow in FIG. 20). (A direction), the hook receiving portion 381 side is more likely to come off than in the direction of the connected rod-shaped member 381 (arrow B direction in FIG. 20). For this reason, the opening direction of the outer lid 38 is set to the arrow B direction in which the connection is difficult to be disconnected. As a result, the outer lid 38 can be turned downward, after being slid rearward, as will be described later. In the bent portion where the direction is changed, even if the movement of the outer lid 38 deteriorates, the connection between the hook portion 381B and the hook receiving portion 381C of the outer lid 38 can be prevented from being disconnected. Note that silicone oil (lubricant) is applied to the connection between the hook portion 381B and the hook receiving portion 381 to improve the movement.

  In this embodiment, the upper surfaces of the plurality of rod-shaped members 381 (the main body of the outer lid 38) connected to each other are covered with a flexible outer lid sheet 382. The thickness of the outer cover sheet 382 is, for example, about 0.5 mm. The outer cover sheet 382 is configured to be curved as the outer cover 38 is bent between the rod-shaped members 381. The outer cover sheet 382 can prevent dust and the like from entering the concave portion 381D formed above the connecting portion of each rod-shaped member 381. In addition, it is better to cover the upper surface of the outer lid 38 with the outer lid sheet 382 than to expose the plurality of rod-shaped members 381 connected like a bath lid. Furthermore, if the upper surface of the outer lid sheet 382 is designed, the design of the drum type washing machine 100 can be improved. However, the outer lid 38 may be configured not to include the outer lid sheet 382.

  FIG. 21 is a vertical cross-sectional view of the drum type washing machine 100, showing a cross-sectional view taken from a vertical plane along the front-rear direction as viewed from the right side. In FIG. 21, the outer cover 38 is omitted. The internal structure of the drum type washing machine 100 according to this embodiment is substantially the same as the internal structure of the drum type washing machine 1 according to the first embodiment (see FIG. 2). About the structure similar to the type washing machine 1, the same code | symbol is attached | subjected to a figure and the description is abbreviate | omitted.

  The upper surface of the upper cover 210 of the drum-type washing machine 100 is, for example, once upwardly convex from both left and right sides of a rear end portion (a portion forming a rear end edge of the opening 4) to the front, and then to the front end. It has a downwardly inclined shape. That is, on the upper surface of the upper cover 210, the left and right sides of the opening 4 are provided with the inclined surface 212 inclined downward toward the front side and the rear of the inclined surface 212, and inclined downward toward the rear. The upper surface of the upper cover 210 is convexly curved so that the position closer to the rear of the upper surface becomes highest. Each of the inclined surfaces 211 and 212 is a convex curved surface.

  The ends of the inclined surfaces 211 and 212 of the upper cover 210 on the opening 4 side receive the left and right side edges of the lower surface of the outer lid 38 (the lower surfaces of the plurality of rod-shaped members 381), and are slid in the front-rear direction along the opening 4. Receiving portion 213 is formed. The upper cover 210 is provided with a guide member 230 facing the receiving portion 213 at a predetermined interval (equal to the thickness of the outer cover 38). The right and left side edges of the upper surface of the outer lid 38 are pressed by the guide members 230 so as not to float from the side edges of the opening 4.

  The rear end of the upper surface of the upper cover 210 (on the rear side of the rear end edge of the opening 4) is slightly inclined so as to become lower toward the rear, and then bends smoothly to form a curved surface 214 that faces downward. I have. The bent surface 214 plays a role of receiving the lower surface of the outer lid 38 slid rearward from the opening 4 side and guiding it vertically to the rear side in the housing 200. In this embodiment, since the inclined surface 211 inclined downward toward the rear is formed on the front side of the curved surface 214, the outer lid 38 that slides backward from the opening 4 side is inclined obliquely along the inclined surface 211. It can be directed to the bending surface 214. Accordingly, the curvature of the bent portion of the bent surface 214 can be increased, so that the outer lid 38 can be guided more smoothly downward along the bent surface 214.

  The rear cover 220 is covered from above so as to face the bent surface 214 of the upper cover 210. Guide surfaces provided on the left and right sides of the lower surface of the upper cover 210 at predetermined intervals (about the same as the thickness of the outer cover 38) at intervals with the bent surface 214 in the attached state, and connected to the lower surface of the guide member 230. 221 are formed. When the outer lid 38 is slid rearward along the side edge of the opening 4, the outer lid 38 passes through the space 222 between the bent surface 214 and the guide surface 221, and enters the housing 200 from the rear side. Will be housed in.

  The bent surface 214 bent in the vertical direction extends only to a position higher than the outer tub 7. That is, the left and right side edges of the outer lid 38 are not guided below the bent surface 214, and the outer lid 38 is accommodated in the rear side in the housing 200 in a vertically hung state. . Thus, with a simple configuration, the outer lid 38 can be accommodated in a vertically elongated narrow space formed behind the outer tub 7. Further, since there is no need to provide a rail (guide member) for guiding the left and right side edges of the outer lid 38 behind the outer tub 7, the outer tub 7 vibrates during operation or the like, and collides with the rail. The rail is not damaged.

  A projection 71 having a guide surface 71A extending in the vertical direction is formed on the rear upper portion of the outer peripheral surface of the outer tub 7. The guide surface 71A of the projecting portion 71 is a smooth surface extending on an extension line below the bent surface 214, and the outer lid 38 slid along the vertical direction to the rear side in the housing 200 is The outer tank 7 side is smoothly fed downward along the guide surface 71A. Therefore, the outer lid 38 can be opened and closed more favorably.

  Usually, since a large number of components (such as ribs) are provided on the outer peripheral surface of the outer tub 7, the end (the rear end) of the outer lid 38, which has been slid vertically along the rear side in the housing 200. When the outer edge of the outer tub 7 interferes with the outer peripheral surface of the outer tub 7, the end of the outer lid 38 is hooked on the above-mentioned constituent members of the outer tub 7, and the outer lid 38 is satisfactorily stored in the rear side of the housing 200. It may not be possible. In this embodiment, the surface of the outer lid 38, which has been slid along the vertical direction to the rear side inside the housing 200, protrudes more rearward than the components on the outer peripheral surface of the outer tank 7. By guiding with the guide surface 71A, it is possible to prevent the end of the outer lid 38 from interfering with the outer tub 7. Therefore, since the outer lid 38 can be reliably accommodated in the rear side of the housing 200 (rearward of the outer tub 7), the outer lid 38 can be more favorably opened. However, a configuration in which the guide surface 71A is not provided may be employed.

  In a state in which the outer lid 38 covers the opening 4 from the rear end to the front end, a force acts on the outer lid 38 in a closing direction by the gravity of the outer lid 38, and the outer lid 38 is closed. On the other hand, when the outer lid 38 is opened to a predetermined position, the force acting on the outer lid 38 is switched to a force in the opening direction by the gravity of the outer lid 38, and thereafter the outer lid 38 is automatically opened. It is similar to the outer lid 31 of the drum-type washing machine 1 according to the first embodiment in that it is opened. When closing the outer lid 38 to the above-mentioned predetermined position, the force acting on the outer lid 38 is switched to a force in the closing direction by the gravity of the outer lid 38, and thereafter, the outer lid 38 is automatically turned off. 38 closes.

  In this embodiment, the direction of the force acting on the outer lid 38 due to the gravity of the outer lid 38 is switched at the predetermined position. Therefore, when the outer lid 38 is opened, when the outer lid 38 is opened from the closed state to the predetermined position. Only by opening the cover, the outer cover 38 is automatically opened thereafter. When closing the outer cover 38, simply closing the outer cover 38 from the open state to the above-described predetermined position, and thereafter, the outer cover 38 is automatically closed. It is supposed to be. Therefore, the outer lid 38 can be more easily opened and closed.

  When the outer lid 38 is opened, the outer lid 38 is housed in the housing 200, so that the drum type washing machine 100 is installed such that the rear surface of the housing 200 is along the wall. Even when this is done, the outer lid 38 does not hit the faucet provided to protrude from the wall surface to introduce water into the drum type washing machine 100.

  FIG. 22 and FIG. 23 are cross-sectional views for describing an attachment mode of the outer lid 38. FIG. 22 is a front view of a cross section when the outer lid 38 is cut along the left-right direction at the bar-shaped member 381, and FIG. The figure which looked at the cross section when cut | disconnected along the direction from the front is shown. Since the mounting manner of the outer lid 38 has the same configuration on both the left and right sides, in FIGS. 22 and 23, only the left-hand attaching manner will be described, and the description of the right-hand attaching manner will be omitted.

  Referring to FIGS. 22 and 23, guide member 230 is a member elongated in the front-rear direction, and has a fitting portion 231 projecting downward at a side edge opposite to opening 4. On the upper surface of the upper cover 210, a fitting recess 215 having a shape corresponding to the fitting portion 231 of the guide member 230 extends in the front-rear direction, and the fitting portion 231 is fitted into the fitting recess 215, whereby the upper surface of the upper cover 210 is formed. Along, the guide member 230 is attached so as to extend in the front-rear direction (see FIG. 21).

  A rib 232 projecting downward is formed on a side edge of the guide member 230 on the opening 4 side. On the upper surface of the upper cover 210, a step portion 216 formed one step lower adjacent to the opening 4 side of the fitting concave portion 215 is disposed, and a side edge of the step portion 216 on the opening 4 side is disposed upward. A protruding rib 217 is formed. The upper end surface of the rib 217 constitutes a receiving portion 213 for receiving and guiding the left and right side edges of the lower surface of the outer lid 38 described above. A space surrounded by the step portion 216 of the upper cover 210, the guide member 230, and the ribs 217 and 232 formed on the side edges on the respective openings 4 side receives and guides the side edges of the outer lid 38. 213A for guiding is formed.

  Referring to FIG. 22, a fitting member 383 is fitted into a through-hole 381A of a predetermined rod-shaped member of the plurality of rod-shaped members 381. The fitting member 383 includes, for example, a fitting portion 383A fitted into the through hole 381A, an upper protruding portion 383B protruding upward from an end opposite to the insertion direction of the fitting portion 383A, and an end opposite to the insertion direction of the fitting portion 383A. And a lower protruding portion 383C protruding downward from the portion. The fitting member 383 is attached so that the fitting portion 383A is fitted into the through hole 381A, and the upper protruding portion 383B and the lower protruding portion 383C are in contact with the end surfaces of the rod-shaped member 381, respectively.

  In a state where the side edge of the outer lid 38 is received by the guide concave portion 213A, the side edge of the lower surface of each rod-shaped member 381 is supported from below by the rib 217 of the upper cover 210, and the fitting member 383 projects upward. The portion 383B and the lower protruding portion 383C are housed in the guide recess 213A. In this state, even when the outer lid 38 is to be displaced to the opposite side to the guide concave portion 213A, the lower protruding portion 383C is hooked on the rib 217 of the upper cover 210, and the upper protruding portion 383B is hooked on the rib 232 of the guide member 230.

  Referring to FIG. 23, a step portion 38C formed one step lower is disposed at a side edge portion of the upper surface of gripping member 38A, and the upper portion of side plate portion 38D of gripping member 38A is higher than step portion 38C. It protrudes. When the side edge of the outer lid 38 is received by the guide recess 213A, the side plate 38D of the gripping member 38A is accommodated in the guide recess 213A, and the lower end surface of the side plate 38D is a stepped portion of the upper cover 210. 216. In this state, the rib 232 of the guide member 230 is opposed to the stepped portion 38C of the gripping member 38A, and even if the outer cover 38 is to be displaced to the opposite side to the guide concave portion 213A, the side plate of the gripping member 38A is displaced. The upper part of the part 38D (the part protruding above the step part 38C) is hooked on the rib 232 of the guide member 230, and the lower part of the side plate part 38D is hooked on the rib 217 of the upper cover 210.

  With the above configuration, when the user opens and closes the outer lid 38, even if a force is applied in a direction intersecting the front-rear direction (for example, the left-right direction), the upper protrusion 383B and the lower Since the protruding portion 383C and the side plate portion 38D of the gripping member 38A are hooked on the ribs 232 and 217 formed on the guide member 230 and the upper cover 210, respectively, the side edge of the outer lid 38 comes off from the guide concave portion 213A. There is no. Therefore, the outer lid 38 can be opened and closed more favorably.

  FIG. 24 is a plan view of the outer lid 38. Among the plurality of rod-shaped members 381, there are rod-shaped members in which the fitting members 383 are fitted in the through holes 381A, and rod-shaped members in which the fitting members 383 are not fitted. In this embodiment, for example, five bar-shaped members 381 in which the fitting members 383 are fitted at both left and right ends are arranged at equal intervals in the front-rear direction with a plurality of the bar-shaped members 381 in which the fitting members 383 are not fitted. ing.

  The outer cover sheet 382 is formed such that the length in the left-right direction is longer than the length of the rod-shaped member, and the left and right ends of the outer cover sheet 382 project laterally beyond the rod-shaped member 381. Since the outer cover sheet 382 is attached so that the lower surface thereof is in contact with the upper surface of the rod-shaped member 381, a rod-shaped member 381 is provided at a side end of the outer lid sheet 382 opposed to the rod-shaped member 381 in which the fitting member 383 is fitted. A through hole 382A is required to penetrate the upper protrusion 383B of the fitting member 383 protruding above the upper surface of the fitting member 383.

  Therefore, in this embodiment, a through hole 382A for penetrating the upper protruding portion 383B is formed at a position corresponding to the upper protruding portion 383B of the rod-shaped member 381 in which the fitting member 383 is fitted. The through hole 382A is formed as a long hole that is longer in the front-rear direction than the upper protrusion 383B of the fitting member 383.

  However, the rod-shaped members 381 in which the fitting members 383 are fitted at both left and right ends are not limited to the configuration in which the plurality of rod-shaped members 381 in which the fitting members 383 are not fitted are arranged at equal intervals in the front-rear direction. The fitting member 383 may be fitted to every other rod-shaped member 381, or the fitting member 383 may be fitted to a plurality of adjacent rod-shaped members 381.

  At the rear end of the outer lid sheet 382, a plurality (for example, three) of mounting holes 382B are formed side by side in the left-right direction. The attachment hole 382B is formed as a long hole extending in the front-rear direction, and the shaft portion 384A of the fixture 384 (for example, a screw) is inserted into the attachment hole 382B from above and attached to the main body of the outer lid 38. Thus, the rear end of the outer cover sheet 382 can be pressed on the lower surface of the head 384B of the fixing tool 384 so as not to float above the upper surface of the main body of the outer cover 38.

  When the outer lid 38 is bent between the respective rod-shaped members 381 and the outer lid sheet 382 is bent accordingly, the mounting position of the fixing member 384 with respect to the mounting hole 382B of the outer lid sheet 382 and the main body of the outer lid 38 is determined. Are shifted in the front-rear direction. In this embodiment, the through-hole 382A is formed in a long hole that is longer in the front-rear direction than the upper protrusion 383B of the fitting member 383, and the mounting hole 382B is formed in a long hole that extends in the front-rear direction. The seat 382 is attached to the main body of the outer lid 38 with a certain amount of play in the front-rear direction. Therefore, when the outer lid 38 is bent, the shaft portion 383A of the fixing member 384 slides in the front-rear direction along the mounting hole 382B, so that the mounting position of the fixing hole 382B and the fixing position of the fixing member 384 as described above. The displacement of the relative position causes the outer cover sheet 382 to bend, thereby preventing the outer cover sheet 382 from floating above the upper surface of the main body of the outer cover 38.

  FIG. 25 is a partially enlarged vertical cross-sectional view near the rear cover 220 of the drum type washing machine 100, and shows a cross-sectional view taken along a vertical plane along the front-rear direction as viewed from the right side.

  In this embodiment, a blade-like elastic member 223 projecting downward is attached to the front edge of the rear cover 220. The length in the left-right direction of the elastic member 223 is substantially equal to the distance between the left and right guide members 230 attached to the upper cover 210. The lower end edge of the elastic member 223 extends below the lower surface of the guide member 230. Therefore, when the outer cover 38 is slid in the front-rear direction to open and close the opening 4, the tip of the elastic member 223 comes into sliding contact with the upper surface of the outer cover 38 (outer cover sheet 382), and is elastically deformed.

  Accordingly, when a relatively thin object (such as a coin) is placed on the outer cover 38 (particularly, a portion where the outer cover 38 is inclined downward toward the rear corresponding to the inclined surface 211 of the upper cover 210). Foreign matter such as the coins can be prevented from sliding rearward on the outer cover 38 and entering the rear inside of the machine through a gap between the upper surface of the outer cover 38 and the rear cover 220.

  FIG. 26 is a view showing a modification of the structure for preventing foreign matter from entering the rear cover 220. FIG. 26 is a right side view of a cross section when the drum type washing machine 100 is cut along a vertical plane along the front-rear direction. 1 shows a partially enlarged longitudinal sectional view as viewed from the side.

  In this modification, a protrusion 385 is formed not at the front end edge of the rear cover 220 but at the rear end of the upper surface of the outer cover 38 to receive foreign substances such as coins sliding backward on the outer cover 38. The ridge 385 is disposed at a position facing the front edge of the rear cover 220 with the outer lid 38 closed, and extends straight between the two guide members 230.

  According to this modification, when the outer lid 38 is closed, the outer lid 38 is placed on the outer lid 38 (particularly, the portion where the outer lid 38 is inclined downward toward the rear corresponding to the inclined surface 211 of the upper cover 210). When a relatively thin object (such as a coin) is placed, the coin or the like is prevented from sliding backward on the outer cover 38 and entering the rear inside of the machine through a gap between the upper surface of the outer cover 38 and the rear cover 220. it can.

  FIG. 27 is a plan view of the drum-type washing machine 100 in a state where the rear cover 220 is removed, and illustrates a front part of the drum-type washing machine 100 without illustration.

  Usually, a water supply valve V for turning on / off the introduction of tap water from the tap water inlet 2F to the inside of the machine or a bath water pump P for sucking bath water into the machine through the bath water inlet 2G is a drum type. It is located at the rear upper end of the washing machine. However, in this embodiment, since the outer cover 38 is slid rearward and accommodated in the rear side of the housing 200, the opening 4 can be opened. If the water supply valve V and the bath water pump P are arranged on the 214, the outer lid 38 that slides backward will be an obstacle. Although it is conceivable to arrange the water supply valve V and the bath water pump P behind the curved surface 214, in this case, a space for arranging the water supply valve V and the bath water pump P behind the curved surface 214 is secured. The depth of the drum-type washing machine is increased.

  Therefore, in this embodiment, the water supply valve V is disposed on the left side (behind the left inclined surface 211) of the curved surface 214 on the upper cover 210, and the bath water pump P is disposed on the left side of the curved surface 214 on the upper cover 210. It is arranged on the right side (behind the right inclined surface 211). Thereby, the water supply valve V and the bath water pump P can be displaced from the slidable region of the outer lid 38, so that the water supply valve V and the bath water pump P obstruct the outer lid 38 that slides backward. The outer lid 38 can be opened and closed favorably. Further, since the water supply valve V and the bath water pump P are disposed in the empty space behind the left and right inclined surfaces 211, the water supply valve V and the bath water pump P can be disposed without increasing the size of the drum type washing machine 100. .

  The tap water introduced into the machine from the tap water inlet 2F via the water supply valve V flows into the detergent container 6 through the tap water supply pipe H1 extending forward from the water supply valve V, and the inside of the detergent container 6 After being mixed with the detergent contained in the outer tub 7, it flows into the outer tank 7.

  The tap water supply pipe H1 is connected to a priming pipe H2 for guiding tap water flowing from the tap water inlet 2F to the bath water pump P side. The bath water pump P is driven to suck a predetermined amount of tap water (so-called priming water) through the priming water inlet pipe H2, and then the bath water is started to be sucked from the bath water inlet 2G to thereby take a bath. It can suck water well. The priming pipe H2 is accommodated in an accommodation recess 214A formed on the curved surface 214 of the upper cover 210, and does not interfere with the outer lid 38 sliding on the curved surface 214.

  The bath water sucked up by the bath water pump P is sent to the detergent container 6 through the bath water supply pipe H3. The bath water supply pipe H3 is guided from the bath water pump P to the left end of the upper cover 210 through the rear end of the upper cover 210 (on the rear side of the curved surface 241), and communicates with the detergent container 6. . Therefore, the bath water sucked up by the bath water pump P is sent from the right side to the left side of the upper cover 210 through the bath water supply pipe H3, and then flows into the detergent container 6.

  However, the present invention is not limited to the configuration in which the water supply valve V is disposed on the left side of the curved surface 214 and the bath water pump P is disposed on the right side of the curved surface 214. May be arranged on the left side of the bending surface 214.

  FIG. 28 is a schematic diagram illustrating a first modification of the opening / closing mechanism of the outer lid 38.

  In this modification, the outer lid 38 can be opened and closed electrically by an electric opening and closing mechanism 300 including a stepping motor M1 instead of opening and closing manually. Therefore, the outer lid 38 can be opened and closed more easily than when the outer lid 38 is opened and closed manually. The configuration of the outer lid 38 is the same as that of the eighth embodiment, and can be bent by connecting a plurality of rod-shaped members 381 to each other so as to be rotatable.

  Gears G that mesh with racks (not shown) formed on the lower surfaces of the left and right side edges of the outer cover 38 are disposed below the left and right side edges of the outer cover 38, respectively. Each gear G is rotatable about a rotation axis R, and a stepping motor M1 is attached to one (for example, right) rotation axis R. The stepping motor M1 is driven to rotate by a fixed angle per pulse based on a periodic input pulse. Therefore, if the input pulse is transmitted to the stepping motor M1 by a preset number of pulses (set pulse number), the rotation shaft R and the gear G are rotated by a fixed angle, and the outer lid 38 is slid by a fixed amount. it can.

  In this modification, the stepping motor M1 is connected to a control unit MC for controlling the operation of the drum type washing machine 100. The control unit MC is configured by, for example, a microcomputer. The operation panel 5 is connected to the control unit MC, and a signal based on the operation of the operation panel 5 is input to the control unit MC.

  When the outer cover 38 is opened, by pressing the cover open button 52 provided on the operation panel 5, the control unit MC, which has received a signal based on the pressing operation, completely opens the outer cover 38. The necessary number of input pulses are transmitted to the stepping motor M1, and the stepping motor M1 is rotationally driven (forward rotation) in one direction. Thereby, the rotation shaft R and the gear G are rotated by a certain angle, and the outer lid 38 is slid by an amount necessary to completely open the opening 4.

  An inner lid 24 for opening and closing the opening 23 of the outer tub 7 and a drum lid 25 for opening and closing the opening 22 of the drum 10, as described in FIG. If it is configured to be opened, the laundry can be taken in and out of the drum 10 by simply opening the inner lid 24 after pressing the lid open button 52 to open the outer lid 38, Convenience is improved.

  On the other hand, the outer lid 38 is configured to be closed in response to a start operation of a start button 51 operated to start the operation of the drum-type washing machine 100. That is, when the start button 51 is pressed, the control unit MC, which has received a signal based on the pressing operation, sets the number of pulses required to completely close the outer cover 38 (the setting when the outer cover 38 is opened). The same number of pulses as the number of pulses is transmitted to the stepping motor M1, and the stepping motor M1 is rotationally driven (reversed) in the other direction. Thereby, the rotation shaft R and the gear G are rotated by a certain angle, and the outer lid 38 is slid by an amount necessary to completely close the opening 4. According to this configuration, after the laundry is stored in the drum 10, simply by pressing the start button 51, the outer lid 38 is automatically closed and the driving operation is started, so that the convenience is improved. .

  In this modification, an inner cover sensor 24A for detecting whether or not the inner cover 24 is closed is connected to the control unit MC. The control unit MC reverses the stepping motor M1 only when the start button 51 is pressed in a state where the inner lid 24 is detected to be in the closed state based on a signal from the inner lid sensor 24A, The outer lid 38 is slid in the closing direction. Thus, if the inner lid 24 is forgotten to be closed, the outer lid 38 will not be closed while the inner lid 24 is open. Can be prevented.

  However, instead of detecting whether the inner lid 24 is closed or not, it is detected whether or not the drum lid 25 is closed, and the outer lid is detected only when it is detected that the drum lid 25 is closed. 38 may be configured to slide in the closing direction.

  The configuration is not limited to the configuration in which the stepping motor M1 is attached to one of the rotation axes R, and the stepping motor M1 may be attached to both of the rotation axes R. In this case, one stepping motor M1 may be driven to rotate when the outer cover 38 is opened, and the other stepping motor M1 may be driven to rotate when the outer cover 38 is closed.

  FIG. 29 is a schematic diagram illustrating a second modification of the opening / closing mechanism of the outer lid 38.

  In this modification, the outer cover 38 can be opened and closed electrically by an electric opening and closing mechanism 400 including a torque motor M2, instead of being opened and closed manually. Therefore, the outer lid 38 can be opened and closed more easily than when the outer lid 38 is opened and closed manually. The configuration of the outer lid 38 is the same as that of the eighth embodiment, and can be bent by connecting a plurality of rod-shaped members 381 to each other so as to be rotatable.

  Similarly to the first modification, gears G that mesh with racks (not shown) formed on the lower surfaces of the left and right side edges of the outer cover 38 are arranged below the left and right side edges of the outer cover 38, respectively. I have. Each gear G is rotatable about a rotation axis R, and a torque motor M2 is attached to each rotation axis R.

  In this modification, each torque motor M2 is connected to a control unit MC for controlling the operation of the drum type washing machine 100. The control unit MC is configured by, for example, a microcomputer. The operation panel 5 is connected to the control unit MC, and a signal based on the operation of the operation panel 5 is input to the control unit MC.

  When the outer lid 38 is opened, by pressing the lid open button 52 provided on the operation panel 5, the control unit MC, which has received a signal based on the pressing operation, drives the one torque motor M2 to rotate. To rotate the torque motor M2 in a direction to open the outer cover 38. At this time, the rotation of the gear G and the rotation shaft R based on the sliding of the outer lid 38 causes the other torque motor M2 to idle.

  For example, a microswitch MS is arranged at a position where the rear end of the outer cover 38 reaches in a state where the outer cover 38 is completely opened (a state shown by a dashed line in FIG. 29). When the outer lid 38 is slid to the fully opened state, the rear end of the outer lid 38 contacts the actuator MS1 of the microswitch MS, and a detection signal based on the displacement of the actuator MS1 is sent from the microswitch MS to the control unit MC. Sent. The control unit MC determines, based on the detection signal from the microswitch MS, that the outer cover 38 has been slid to the fully opened state, and stops the rotation driving of the one torque motor M2. As a result, the outer lid 38 is kept open by its own weight.

  An inner lid 24 for opening and closing the opening 23 of the outer tub 7 and a drum lid 25 for opening and closing the opening 22 of the drum 10, as described in FIG. If it is configured to be opened, the laundry can be taken in and out of the drum 10 by simply opening the inner lid 24 after pressing the lid open button 52 to open the outer lid 38, Convenience is improved.

  On the other hand, the outer lid 38 is configured to be closed in response to a start operation of a start button 51 operated to start the operation of the drum-type washing machine 100. That is, when the start button 51 is pressed, the control unit MC, which has received a signal based on the pressing operation, transmits a signal for rotationally driving the other torque motor M2, and turns the torque motor M2 to the outer cover 38. Is rotated in the closing direction. At this time, the rotation of the gear G and the rotation shaft R based on the sliding of the outer lid 38 causes one of the torque motors M2 to idle.

  For example, a reed switch LS is disposed at a position where the front end of the outer cover 38 reaches when the outer cover 38 is completely closed (a state indicated by a solid line in FIG. 29), that is, near the front edge of the opening 4. The contact of the reed switch LS is changed in response to a change in the magnetic field formed by a magnet (not shown) attached to a position corresponding to the reed switch LS on the front edge of the outer lid 38 due to the sliding of the outer lid 38. It is a contact / non-contact (on / off). When the outer lid 38 is slid to the completely closed state, the reed switch LS is turned on, and a detection signal to that effect is transmitted from the reed switch LS to the control unit MC.

  In this modification, a lock device L for locking the outer lid 38 in a closed state is disposed near the front edge of the opening 4. The lock device L is provided with a pin L1 that can be displaced along the axial direction. A lock projection 386 having a through hole 386A is formed on the front edge of the outer lid 38. When the control unit MC determines that the outer lid 38 has been slid to the completely closed state based on the detection signal from the reed switch LS, the control unit MC displaces the pin L1 of the lock device L, and The outer lid 38 is locked in a closed state by being inserted through the through hole 386A. Thereafter, the control unit MC stops the rotation driving of the other torque motor M2.

  According to this configuration, after the laundry is stored in the drum 10, simply by pressing the start button 51, the outer lid 38 is automatically closed and locked by the lock device L, and then the driving operation starts. Therefore, convenience is improved.

  In this modification, an inner cover sensor 24A for detecting whether or not the inner cover 24 is closed is connected to the control unit MC. The control unit MC reverses the other torque motor M2 only when the start button 51 is pressed in a state where the inner cover 24 is detected to be in the closed state based on a signal from the inner cover sensor 24A. Then, the outer lid 38 is slid in the closing direction. Thus, if the inner lid 24 is forgotten to be closed, the outer lid 38 will not be closed while the inner lid 24 is open. Can be prevented.

  However, instead of detecting whether the inner lid 24 is closed or not, it is detected whether or not the drum lid 25 is closed, and the outer lid is detected only when it is detected that the drum lid 25 is closed. 38 may be configured to slide in the closing direction.

  The configuration is not limited to the configuration in which the torque motor M2 is attached to both the rotation shafts R, and the torque motor M2 may be attached to only one of the rotation shafts R. In this case, when the outer lid 38 is opened, the torque motor M2 may be rotationally driven (forward rotation) in one direction, and when the outer lid 38 is closed, the torque motor M2 may be rotationally driven (reversed) in the other direction.

  In the first and second modified examples, the configuration in which the outer lid 38 is opened and closed by the rotation of the gear G that meshes with the rack formed on the lower surface of the outer lid 38 has been described. However, the present invention is not limited to such a configuration. A rotating body that comes into contact with the lower surface of the outer lid 38, and the outer lid 38 can be opened and closed by a frictional force acting between the peripheral surface of the rotating body and the lower surface of the outer lid 38. Is also good. Further, the configuration may be such that the outer lid 38 can be opened and closed by winding up and rewinding the wire connected to the outer lid 38 with a motor.

  When the outer lid 38 is opened, the rotation speed of the motor is decreased immediately before the outer lid 38 is completely opened, and when the outer lid 38 is closed, the rotation speed of the motor is decreased immediately before the outer lid 38 is completely closed. It may be. In this case, it is possible to prevent the outer lid 38 from opening and closing vigorously to be damaged.

  Next, an opening / closing mechanism for an outer lid according to a ninth embodiment of the present invention will be described. This opening / closing mechanism is an improvement of the opening / closing mechanism of the outer lid in the drum type washing machine according to the eighth embodiment. The same components as those in the eighth embodiment are denoted by the same reference numerals in the drawings. The description is omitted.

  Slide assisting members are provided on both sides of the gripping member 38A to reduce resistance when the outer lid 38 slides and to smoothly open and close the outer lid 38.

  FIG. 30 is a longitudinal sectional view of a main part around a gripping member 38A, showing an embodiment in which a sled member is provided as a slide assisting member. A sled member 500 that slides on the receiving portion 213 of the upper cover 210 when the outer lid 38 is slid is attached to both sides of the gripping member 38A by, for example, two screws 501. The sled member 500 is made of a material that is more slippery (has a lower friction coefficient) than the gripping member 38A and has excellent wear resistance, for example, a polyacetal resin or a nylon resin. By providing such a sled member 500, the outer lid 38 can be smoothly opened and closed, and the receiving portion 213 of the upper cover 210 can be prevented from being scraped by sliding with the gripping member 38A side.

  The front and rear dimensions of the sled member 500 are longer than the front and rear dimensions of the gripping member 38A. Even if there is a gap between the upper end of the sled member 500 and the lower surface of the guide member 230, the gripping member 38A will be loose. I try to make it difficult. Thereby, the outer lid 38 can be slid more smoothly. In addition, the lower end surface 500 </ b> A of the sled member 500 (the sliding surface with the receiving portion 213) has a concave curved surface so as to correspond to the convex curved surface of the receiving portion 213. The curvature is adjusted to the smallest curvature of the convex curved surface of the receiving portion 213. Thereby, the sliding contact portion of the lower end surface 500A of the sled member 500 with the receiving portion 213 is increased as much as possible.

  FIG. 31 is a longitudinal sectional view of a main part around a gripping member 38A, showing an embodiment in which a roller member is provided as a modification of the slide assisting member. Roller members 502 are attached to both sides of the gripping member 38A. The roller member 502 includes a holding member 503 having a front and rear roller shaft 503A, and two members that are rotatably attached to the roller shaft 503A and that roll the receiving portion 213 of the upper cover 210 when the outer lid 38 is slid. Roller 504. The front and rear dimensions of the holding member 503 are longer than the front and rear dimensions of the gripping member 38A.

  In addition, as the slide holding member, for example, a top member that slides on the receiving portion 213 can be employed. Further, a PE sheet (polyethylene sheet) may be affixed as a slide assist member to both edges on the back surface of the outer lid 38 and facing the receiving portion 213. In this case, the sliding of the outer lid 38 itself is improved, and the outer lid 38 can slide more smoothly. Further, in this case, when a layer having a cushioning property is provided between the PE sheet and the outer lid 38 by, for example, thickening an adhesive layer when fixing the PE sheet, the outer lid 38 is slid. Sound when the sound is played can be reduced.

  FIG. 32 is a longitudinal sectional view of the front portion of the upper cover 210, showing a state in which the outer lid 38 is closed. In a portion facing the receiving portion 213 on the back surface of the front edge portion of the guide member 230, a built-up portion 505 (resistor) that slightly rises downward is formed. The overlay portion 505 is in sliding contact with the upper end surface 500B of the sled member 500 shortly before the gripping member 38A hits the front edge 4A of the opening 4 of the upper cover 210, that is, shortly before the outer lid 38 is completely closed. Thus, resistance is applied to the sled member 500. As a result, even if the user closes the outer lid 38 vigorously, the momentum is weakened before the gripping member 38A hits the front edge 4A of the opening 4, so that a large impact is applied to the gripping member 38A and the opening front edge 4A. Can be prevented. Further, the overlay portion 505 contacts the upper end surface 500B of the sled member 500 when the outer lid 38 is completely closed. Thus, since the sled member 500 stops moving up and down, the gripping member 38A can prevent the vibrating due to vibration during dehydration or the like.

  Although not shown, a build-up portion that functions in the same manner as the build-up portion 505 at the front edge is also formed on the back surface of the rear edge of the guide member 230, so that the user can open the outer lid vigorously. However, since the momentum is weakened before the gripping member 38A hits the rear edge of the opening, it is possible to prevent a large impact from being applied to the gripping member 38A and the rear edge of the opening.

  The outer lid 38 is slid on a portion of the back surface of the guide member 230 facing the receiving portion 213 except for the above-mentioned front and rear overlay portions (a portion between the front edge portion and the rear edge portion). At this time, a PE sheet 506 (a member for improving the slip) is attached so that the upper end surface 500B of the sled member 500 does not easily become a resistance when the sled member 500 hits. Thereby, opening and closing of the outer lid 38 can be performed more smoothly.

  The sliding surface of the receiving portion 213 of the upper cover 210, the lower end surface 500A of the sled member 500, the surface of the PE sheet 506 on the back surface of the guide member 230, and the receiving portion 213 on the back surface of the outer lid 38 (the PE sheet is stuck). In this case, silicone oil (lubricant) is applied to the surface of the PE sheet) to improve the slip. Thereby, opening and closing of the outer lid 38 can be performed more smoothly.

  FIG. 33 is a longitudinal sectional view of a main part around the gripping member 38A, showing a mounting structure of the gripping member 38A and the outer lid 38. A mounting boss 507 for mounting the outer lid 38 is provided on the rear surface of the gripping member 38A and at a position behind the center when viewed from the side. The plurality of mounting bosses 507 are formed side by side in the longitudinal direction (left-right direction) of the gripping member 38A. A mounting hole 508 corresponding to a mounting boss is provided in the leading rod-shaped member 381 constituting the outer lid 38. The inner diameter of the mounting hole 508 is slightly larger than the outer shape of the mounting boss 507. The outer cover sheet 382 is also provided with a mounting hole 509. The height of the mounting boss 507 is higher than the thickness of the rod 381, and the tip of the mounting boss 507 protrudes from the lower surface of the rod 381 in a state where the mounting boss 507 passes through the mounting hole 508. In this state, the screw 511 is attached to the attachment boss 507 via the washer 510, so that the rod-shaped member 381, that is, the outer lid 38 is attached to the gripping member 38A. At this time, since the diameter of the head of the washer 510 and the screw 511 is larger than the inner diameter of the mounting hole 508, the rod-shaped member 381 does not come off from the mounting boss 507. In this mounting structure, there is a gap between the washer 510 and the lower surface of the rod 381, and the lower surface of the rod 381 is not pressed by the screw 511. That is, the rod-shaped member 381 is attached to the gripping member 38A so as to be movable in a predetermined range in the vertical and horizontal directions. Therefore, when the outer lid 38 slides on the convexly curved receiving portion 213, the connecting portion between the gripping member 38A and the outer lid 38 can also be bent in accordance with the bending, and the outer lid 38 is smoothly opened and closed. be able to.

  On the back surface of the front wall of the gripping member 38A, a plurality of ribs 512 are formed in a row in the longitudinal direction of the gripping member 38A toward the leading bar-shaped member. The rib 512 is configured such that, when the leading rod-shaped member 381 moves forward, before the rear edge of the mounting hole 508 contacts the rear side of the mounting boss 507, the rib 512 hits the hook portion 381B of the rod-shaped member 381. Have been. Therefore, even if the outer lid 38 is closed vigorously and the bar-shaped member 381 moves forward vigorously, the rear edge of the mounting hole 508 does not contact the rear side of the mounting boss 507, so that a large impact is applied to the mounting boss 507. Is not added, and the mounting boss 507 can be prevented from being damaged.

  FIG. 34 is an enlarged vertical cross-sectional view near the rear cover 220, showing a detailed structure of the rear portion of the upper cover 210 covered by the rear cover 220. On the back surface of the front part of the rear cover 220, a reinforcing metal member 513 as a reinforcing member is attached with a screw 514. The left and right lengths of the reinforcing fitting 513 are substantially equal to the distance between the left and right guide members 230 attached to the upper cover 210. In this way, even if a heavy object such as a detergent container is placed on the central portion of the front portion of the rear cover 220, the front central portion sinks down because the back surface of the front portion is reinforced by the reinforcing metal fittings 513. This is unlikely to occur, and the storage opening 220A of the outer lid 38 into the rear cover 220 can be prevented from being narrowed, so that the smooth opening and closing operation of the outer lid 38 can be prevented.

  Below the reinforcing metal fitting 513, there is provided a floating prevention member 515 that slides on the outer lid sheet 382 and prevents the outer lid sheet 382 from floating when the outer lid 38 slides. The floating prevention member 515 is made of a material softer than the outer cover sheet 382, for example, felt so as not to damage the outer cover sheet 382. The left and right lengths of the floating prevention member 515 are substantially equal to the left and right lengths of the reinforcing bracket 513. In addition, when a foreign substance attempts to enter from the storage opening 220A of the outer lid 38, the entry is prevented by the floating prevention member 515. Therefore, the floating prevention member 515 can also function as a foreign matter entry prevention member.

  The distance between the bent surface 214 of the upper cover and the guide surface 221 of the rear cover 220 and the distance between the bent surface and the guide portion 210A of the upper cover (provided at the rear end of the upper cover so as to follow the guide surface), that is, If the width of the slide path of the bent portion where the sliding direction of the outer lid 38 changes is too narrow with respect to the thickness of the outer lid 38, the outer lid 38 may be caught and may not move smoothly. Therefore, it is necessary to increase the width to some extent. In this case, however, the outer lid 38 becomes easy to dance at the bent portion, and there is a possibility that sound is produced. Therefore, an elastic member is provided for urging the portion of the outer lid 38 immediately after bending downward to the rear. Specifically, a leaf spring member 516 is attached to the bent surface 214 as an elastic member. Further, the front cover 210A is urged by the leaf spring member 516 against the front surface of the guide portion 210A, so that even if the outer cover 38 strongly contacts the guide portion 210A side (the guide side that guides the front side of the outer cover 38), the outer cover 38 can be used. A protective member 517 is provided so that the sheet 382 is not damaged and does not cause sliding resistance. The protective member 517 is made of a member that is softer and more slippery than the outer lid sheet 382, for example, a felt sheet. With such a configuration, even if the width of the slide path at the bent portion is widened, the outer cover 38 is less likely to dance, preventing generation of sound and smoothly opening and closing the outer cover 38.

  Below the upper cover 210, a part of the air path member 518 constituting the drying air path slightly protrudes into a path in which the outer lid 38 hangs down. For this reason, when the outer lid 38 hits the air path member 518, it escapes to the rear side. At this time, the following ingenuity has been taken to escape more smoothly. That is, in order to make the surface of the air path member 518 that the outer cover 38 contacts a curved surface, the upper part of the air path member 518 is covered with the cover 519 that forms the curved surface. The cover 519 is formed by, for example, bending a sheet made of a polypropylene resin. In addition, the outer lid 38 is configured such that the rigidity of the rear end portion thereof is smaller than the rigidity of the front portion thereof, so that the outer lid 38 is easily bent inward but hardly bent (hardly bent) outwardly (front side) due to its structure. The rear end portion of the outer lid 38 is configured to be easily warped.

  FIG. 35 is a plan view of the outer lid 38 as viewed from the back. As shown in this figure, at the rear of the outer lid 38, the length of some rod-shaped members 381 is shortened. Specifically, the length of the second and sixth rod-shaped members 381 from the tail is about one-third of the other length, and the rear part has a shape similar to a fish bone. The portion of the outer lid 38 whose rear portion has reduced rigidity enters the rear cover 220 with the outer lid 38 completely closed, and does not appear on the front. In this way, even if a part of the air path member 518 (a component provided in the outer tub) constituting the drying air path protrudes into the path along which the outer lid 38 hangs down (even if the air path member 518 may protrude). ), The rigidity of the rear end portion of the outer cover 38 is reduced to make it easier to warp rearward, and the surface to which the outer cover 38 contacts (a surface that can be contacted) is curved, so that the outer cover 38 hits the air path member 518. When this happens, the vehicle can smoothly escape to the rear side, and the opening and closing of the outer lid 38 can be performed smoothly. When the air passage member 518 has a small amount of protrusion, that is, when the degree of escape is small, either the contact surface may be a curved surface or the rigidity of the rear end portion of the outer lid 38 may be reduced.

  FIG. 36 is a longitudinal sectional view showing the configuration of the rear part of the outer lid 38. As shown in this figure, by arranging the weight 520 at the rear end of the outer cover sheet 382, the outer cover sheet 382 can be pulled, and the outer cover sheet 382 when the outer cover 38 is slid. Floating (undulation) can be prevented.
