Description

The present invention relates to washing machines.

For example, Patent Document 1 describes a washing machine in which an upper opening of a water tub elastically supported in an outer box is closed by a tub cover having an opening in the center, and the opening is opened and closed by an inner lid. . In the washing machine disclosed in Patent Literature 1, a handle to be rotated is provided on the inner lid. The handle is provided with a hook member having a claw. When the inner lid is closed, the claw portion of the hook member engages with the claw portion of the locking member provided on the tank cover side, and the inner lid is held in the closed state.

In this way, when a claw portion structure is employed to hold the inner lid in a closed state, the claw portion structure is exposed to the outside when the inner lid is opened. When the lid is viewed by the user, it does not necessarily look good.

Therefore, in order to improve the appearance of the inner cover, it is conceivable to employ a structure in which a magnet is used and the inner cover is held in a closed state by the attractive force of the magnet.

For example, in US Pat. No. 5,300,000, it is described that a magnet is used in a washing machine to keep the lid closed on the detergent dispenser.

JP 2010-200943 A JP 2005-514133 A

When a magnet is used to keep the lid of the detergent supply device closed as in Patent Document 2, the user can easily open and close the lid because the attraction force may be weak.

On the other hand, a large force is likely to be applied to the inner lid in the opening direction due to the vertical vibration of the water tank that may occur during dehydration and the collision of the laundry against the inner lid that may occur during washing. Therefore, when a magnet is used to keep the inner lid closed, a strong attractive force is required. Therefore, in this case, there is a concern that it may become difficult for the user to perform the opening/closing operation.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a washing machine in which a user can easily open and close the outer tub lid when the outer tub lid covering the opening on the upper surface of the outer tub is closed and held by a structure using a magnet. With the goal.

A washing machine according to a main aspect of the present invention comprises an outer tub elastically supported in a housing, a washing/dehydrating tub rotatably disposed in the outer tub to accommodate laundry, and an outer tub. an outer tank lid that closes the opening provided on the upper surface. Here, the outer tank lid has a first rotating shaft at one end thereof, and is opened and closed by rotating about the first rotating shaft with respect to the outer tank, and the other end has the above-described It has a handle rotatable about a second axis of rotation parallel to the first axis of rotation. The handle has a first arrangement surface facing the upper surface of the outer tub when the outer tub cover closes the opening, and a first adsorption surface arranged within the first arrangement surface. a handhold portion provided so as to be separated from the first attraction surface in the direction in which the first rotation shaft and the second rotation shaft are aligned, and on which a user's hand can be placed. The upper surface of the outer tank is arranged within a second arrangement surface corresponding to the first arrangement surface and within the second arrangement surface, and in a state where the outer tank lid closes the opening, the first arrangement surface is arranged. and a second attracting surface with which the attracting surface of is in contact. One of the first attraction surface and the second attraction surface generates a magnetic force by a magnet, and the other surface is attracted to the one surface by the generated magnetic force. When the handle portion is lifted while the outer tank lid closes the opening, a fulcrum is positioned on the first arrangement surface opposite to the handle portion with the first adsorption surface interposed therebetween. The first arranging surface rotates about the fulcrum, and the first attracting surface separates from the second attracting surface.

According to the above configuration, the first attraction surface is moved away from the second attraction surface by the principle of leverage with the grip portion as the point of force and the contact area of the first attraction surface with the second attraction surface as the point of action. Can be pulled apart easily. This allows the user to easily open and close the outer tank lid.

In the washing machine according to this aspect, the second arrangement surface is configured to be higher than the upper surface of the outer tub, and the first arrangement surface is arranged in the direction opposite to the direction of the handle portion. 2, and a space may be formed between the overhanging surface portion and the upper surface of the outer tub.

According to the above configuration, the fulcrum can be formed not at the end of the first placement surface but at a portion of the first placement surface near the first attraction surface. The distance to the contact area of the attraction surface can be shortened. As a result, a large upward force is likely to be applied to the contact area of the first attraction surface, and the first attraction surface can be more easily separated from the second attraction surface.

In the case of the above configuration, the first arrangement surface further protrudes toward the upper surface side of the outer tank on the opposite side of the first attraction surface from the handhold portion and serves as the fulcrum. A protrusion may be provided. In this case, the upper surface of the outer tub is provided with an inclined surface that descends toward the space so as to continue from the second arrangement surface and that is in contact with the projection.

When the handle rotates by lifting the handle, the second rotating shaft moves upward accordingly, and the outer tub cover rotates about the first rotating shaft to open slightly. A horizontal pulling force is applied to the handle when the outer tank lid is opened. In the above configuration, when the handle is pulled horizontally, the inclined surface is horizontally pushed by the protrusion, and this horizontal force is converted into an upward force and acts on the protrusion. As a result, the protrusion rises along the inclined surface and rises at the same time as the handle rotates, so that the first attraction surface can be more easily separated from the second attraction surface.

In the above configuration, the protrusion may be configured to have a surface parallel to the inclined surface.

With such a configuration, the parallel surfaces of the protrusions are in almost surface contact with the inclined surface, so that the inclined surface can be favorably pushed backward by the protrusions, and the upward direction converted by the inclined surface can be obtained. Sufficient force can be applied to the protrusion. This makes it easier to raise the handle, and makes it possible to separate the first attraction surface from the second attraction surface even more easily.

With the above configuration, the tip of the protrusion may further have an R shape.

With such a configuration, when the rotation of the handle progresses, the tip portion is less likely to get caught on the inclined surface, and the handle can be rotated smoothly.

In the washing machine according to this aspect, the one surface may be the surface of the magnet. In this case, the other surface is composed of the surface of the magnetic material.

According to the above configuration, the first adsorption surface and the second adsorption surface can be strongly attracted to each other, and the opening can be firmly closed by the outer tank lid.

According to the present invention, a user can easily open and close the outer tank lid when the outer tank lid that covers the opening on the upper surface of the outer tank is closed and held by a structure using a magnet.

The drive unit 30 includes a drive motor 31 and a transmission mechanism section 32 . The transmission mechanism unit 32 has a clutch mechanism, and the switching operation by the clutch mechanism transmits the torque of the drive motor 31 only to the pulsator 26 to rotate only the pulsator 26 in the washing process and the rinsing process, and rotates only the pulsator 26 in the dewatering process. , the torque of the drive motor 31 is transmitted to the pulsator 26 and the washing/dehydrating tub 24 to integrally rotate the pulsator 26 and the washing/dehydrating tub 24 .

An outer bottom portion of the outer tub 20 is formed with a drain port portion 20a. A drain valve 40 is provided in the drain port portion 20a. The drain valve 40 is connected to the drain hose 41 . When the drain valve 40 is opened, the water stored in the washing/dehydrating tub 24 and the outer tub 20 is drained out of the machine through the drain hose 41 .

A drying device 50 and a water supply device 60 are arranged above the outer tub 20 in the rear part of the housing 10 . The drying device 50 and the water supply device 60 are attached to a fixed plate 16 arranged on the upper rear portion of the body portion 11 and covered by the upper plate 12 .

The drying device 50 dries the laundry stored in the washing/dehydrating tub 24 . The drying device 50 includes a circulation air passage 50a in which a heater and a blower fan are arranged, and the circulation air passage 50a is connected to the inside of the outer tub 20 by an intake duct 71 and an exhaust duct 72. As shown in FIG. The intake duct 71 and the exhaust duct 72 are flexible ducts made of an elastic material such as rubber, and have a bellows portion (not shown) in the intermediate portion. Hot air generated by the operation of the heater and blower fan is discharged from the circulation air passage 50 a and introduced into the outer tub 20 through the intake duct 71 . Further, hot air discharged from the outer tub 20 is introduced into the circulation air passage 50a through the exhaust duct 72. As shown in FIG. Thus, warm air circulates between the circulation air passage 50a and the outer tub 20. As shown in FIG.

The drying device 50 performs a circulating drying operation by circulating hot air, followed by an exhaust drying operation for discharging part of the circulating hot air to the outside. The upper plate 12 is provided with an exhaust port 51 which is composed of a large number of exhaust holes and through which hot air is discharged.

The water supply device 60 has a water supply port 61 exposed to the outside connected to an external water supply hose (not shown) extending from a faucet. The water supply device 60 includes a water supply valve and a detergent container. When the water supply valve is opened, tap water from the faucet is supplied into the outer tub 20 together with the detergent contained in the detergent container. Water supply device 60 may include a bath water pump.

In the fully automatic washing/drying machine 1, washing operation, washing/drying operation, or drying operation of various operation courses is performed. The washing operation is an operation in which only washing is performed, and a washing process, an intermediate dehydration process, a rinsing process and a final dehydration process are executed in order. The washing/drying operation is an operation in which washing and drying are continuously performed, and the final dehydration step is followed by the drying step. The drying operation is an operation for performing only drying, and only the drying process is performed.

In the washing process and the rinsing process, the pulsator 26 rotates rightward and leftward while water is stored in the washing/dehydrating tub 24 . The rotation of the pulsator 26 generates a water flow in the washing/dehydrating tub 24 . In the washing process, the laundry is washed by the generated water flow and the detergent contained in the water. In the rinsing process, the laundry is rinsed by the generated water flow.

In the intermediate dehydration process and the final dehydration process, the washing/dehydration tub 24 and the pulsator 26 rotate together at high speed. The laundry is dehydrated by the action of the centrifugal force generated in the washing/dehydrating tub 24 .

In the drying process, the internal air circulation drying process is performed first, followed by the external air introduction drying process. In the internal air circulation drying process, the drying device 50 performs a circulation drying operation, and warm air circulates between the circulation air passage 50 a and the outer tub 20 . Due to the circulation of the dry air, the temperature inside the washing/dehydrating tub 24 rises quickly. The pulsator 26 is rotated, and the laundry is dried by circulating warm air while being agitated. When the temperature in the washing/dehydration tub 24 increases and water evaporates from the laundry and the warm air contains a large amount of water, the process is switched to the outside air introduction drying process. In the outside air introduction drying step, the drying device 50 performs an exhaust drying operation, introduces outside air into the circulation air passage 50a, and exhausts part of the hot air circulating from the circulation air passage 50a. Moisture evaporated from the laundry is effectively discharged from the inside of the outer tub 20 to the outside of the housing 10, and the inside of the outer tub 20 is easily dehumidified, thereby promoting the drying of the laundry.

Next, the opening/closing operation of the outer tub lid 23 will be described.

FIG. 7A is a cross-sectional view of main parts of the outer tank cover 100 and the outer tank lid 23, showing the periphery of the handle 300 with the outer tank lid 23 closed, according to the present embodiment. FIG. 7B shows the outer tank cover 100 and the outer tank lid 23 according to the present embodiment, showing the periphery of the handle 300 in a state where the handle 300 is rotated to open the outer tank lid 23. It is a cross-sectional view of the part. Although FIGS. 7A and 7B show the packing 230 in an uncompressed state, the packing 230 is actually crushed and is in contact with the surface of the outer tank cover 100. .

As shown in FIG. 7( a ), when the outer tank lid 23 is closed and the inner input port 101 is blocked by the outer tank lid 23 , the handle-side adsorption surface 322 of the handle 300 moves toward the outer tank side of the outer tank cover 100 . The handle-side attracting surface 322 is attracted to the outer-tank-side attracting surface 161 by the magnetic force of the magnet 160 generated by the outer-tank-side attracting surface 161 in contact with the attracting surface 161 . Here, the adsorption force between the handle-side adsorption surface 322 and the outer-tub-side adsorption surface 161 is stronger than the elastic force of the packing 230, and the vertical vibration of the outer tub 20 during dehydration and the outer-tub lid during washing, etc. The force can be stronger than the upward force that can be generated on the outer tub lid 23 due to the collision of the laundry against 23 .

The handle-side arrangement surface 335 protrudes forward of the outer-tub-side arrangement surface 151 , that is, in the direction opposite to the grip portion 315 of the handle 300 , and the protruding surface portion and the outer-tub cover 100 , that is, the upper surface of the outer-tub 20 . A space S is formed between. Furthermore, the handle-side inclined surface 337 of the protrusion 336 provided on the handle-side arrangement surface 335 is parallel to the outer tank-side inclined surface 152 and is in a state of being substantially in contact therewith.

When opening the outer tank lid 23, the user puts his or her finger on the handle portion 315 of the handle 300 and lifts the handle portion 315 obliquely upward and forward. As shown in FIG. 7B, when the handle 315 is lifted, the handle-side inclined surface 337 of the projection 336 comes into contact with the outer tank-side inclined surface 152, and the handle 300 rotates forward with the projection 336 as a fulcrum. move. As a result, the handle-side arrangement surface 335 rotates, and the handle-side attracting surface 322 is separated from the outer tank-side attracting surface 161 . At this time, the grip portion 315 is the point of force, the projection portion 336 is the fulcrum, and the contact area of the handle side attraction surface 322 with the outer tank side attraction surface 161 is the point of action. Since a large force acts upward, the handle-side attracting surface 322 is easily separated from the outer tank-side attracting surface 161 .

When the handle 300 rotates forward, the handle rotation axis R2 moves upward accordingly, and the lid main body 200, that is, the outer tank lid 23 rotates about the lid rotation axis R1 and moves upward. and slightly open. When the outer tub lid 23 rotates, the handle rotation axis R2 moves upward and obliquely backward rather than directly upward, so a force is applied to the handle 300 to pull the handle 300 backward. In the handle 300, the protrusion 336 is in contact with the outer tank side inclined surface 152, so the outer tank side inclined surface 152 is pushed backward by the protrusion 336, and this rearward force is converted into an upward force. It will act on the protrusion 336 . As a result, the protrusion 336 rises along the outer-tub-side inclined surface 152 and rises simultaneously with the rotation of the handle 300 , so that the handle-side attracting surface 322 is more easily separated from the outer-tub-side attracting surface 161 . .

Here, a handle-side inclined surface 337 parallel to the outer tank-side inclined surface 152 is formed on the projection 336, and when the projection 336 first contacts the outer tank-side inclined surface 152, the handle-side inclined surface 337 makes almost surface contact with the outer tank side inclined surface 152 . Therefore, the handle-side inclined surface 337 can favorably push the outer-tub-side inclined surface 152 rearward, and the upward force converted by the outer-tub-side inclined surface 152 is favorably applied to the protrusion 336 . Further, as the handle 300 rotates forward, the distal end portion 338 of the protrusion 336 comes into contact with the outer-tub-side inclined surface 152 . Since the tip portion 338 of the projection portion 336 is R-shaped, it is less likely to get caught on the outer tub-side inclined surface 152, and the handle 300 can be rotated smoothly.

When the handle-side attracting surface 322 is separated from the outer tank-side attracting surface 161 , the user rotates the outer tank lid 23 backward while holding the handle 300 to open the outer tank lid 23 widely. As a result, the inner inlet 101 is opened.

<Effect of Embodiment>
As described above, according to the present embodiment, the principle of leverage with the protrusion 336 as the fulcrum, the grip portion 315 as the force, and the contact area of the handle-side attraction surface 322 with the outer tank-side attraction surface 161 as the point of action, The handle-side attracting surface 322 can be easily separated from the outer tank-side attracting surface 161 . This allows the user to easily open and close the outer tank lid 23 .

Further, according to the present embodiment, since the space S is formed between the handle-side arrangement surface 335 and the outer tank cover 100 in front of the handle-side attraction surface 322, the front end portion of the handle-side arrangement surface 335 Instead, a protrusion 336 that serves as a fulcrum can be formed on a portion of the handle-side arrangement surface 335 near the handle-side attracting surface 322 . As a result, the distance from the projection 336 as the fulcrum to the contact area of the handle-side attracting surface 322 as the point of action can be shortened, so that a large upward force is likely to be applied to the contact area of the handle-side attracting surface 322 . Therefore, the handle-side attracting surface 322 can be more easily separated from the outer tank-side attracting surface 161 .

Furthermore, according to the present embodiment, when the handle 300 is rotated, the protrusion 336 is in contact with the outer tank-side inclined surface 152, and the handle 300 generated when the handle 300 is rotated is moved backward. Since the force is converted into an upward force and acts on the protrusion 336, the protrusion 336 can be lifted along the outer tank-side inclined surface 152, and the handle 300 can be rotated and rotated at the same time. can be raised. This makes it possible to separate the handle-side attracting surface 322 from the outer tank-side attracting surface 161 even more easily.

Furthermore, according to the present embodiment, the handle-side inclined surface 337 formed on the protrusion 336 is brought into almost surface contact with the outer-tub-side inclined surface 152 , so that the outer-tub-side inclined surface 152 is supported by the handle-side inclined surface 337 . It can be pushed backward well, and the upward force converted by the outer tank side inclined surface 152 can be sufficiently applied to the protrusion 336 . As a result, the handle 300 can be easily lifted, and the handle-side attracting surface 322 can be separated from the outer tank-side attracting surface 161 even more easily.

Furthermore, according to the present embodiment, the tip 338 of the protrusion 336 is R-shaped, so that when the handle 300 is rotated forward, the tip 338 is inclined toward the outer tub-side inclined surface 152 . It is possible to rotate the handle 300 smoothly without being caught by the handle 300 .

Furthermore, according to the present embodiment, the handle-side attracting surface 322 is composed of the lower surface of the attracting fitting 320, and the outer tank-side attracting surface 161 is composed of the upper end surface 160a of the magnet 160. Since the magnet 160 is in direct contact with the magnet 160, the handle-side attracting surface 322 and the outer-tank-side attracting surface 161 can be strongly attracted to each other. Therefore, the inner inlet 101 can be firmly closed by the outer tank lid 23 .

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and the embodiments of the present invention can be modified in various ways other than those described above. be.

For example, in the above-described embodiment, a configuration is adopted in which attraction metal fitting 320 and magnet 160 are in direct contact with each other. However, as shown in FIG. 8(a), by not providing the opening 334 in the bottom wall surface portion 331 of the metal fitting holder 330 and covering the upper end surface 160a of the magnet 160 with the cover 154, the attracting metal fitting 320 and the magnet 160 do not directly contact each other. In this case, the projection range of the lower surface of the attraction fitting 320 on the outer surface of the bottom wall portion 331 of the metal fitting holder 330 is the handle side attraction surface 322, and the projection range of the upper end surface 160a of the magnet 160 on the upper surface of the cover 154 is the outer tank side attraction. It becomes the surface 161 . An opening 334 may be provided in the bottom wall surface portion 331 of the metal fitting holder 330, and the upper end surface 160a of the magnet 160 may be covered with a cover 154. A configuration in which the opening 334 is not provided and the upper end surface 160a of the magnet 160 is not covered with the cover 154 may be adopted. In the configuration as described above, it is desirable that the magnetic force of the magnet 160 is stronger than that in the above embodiment.

Further, in the above-described embodiment, the magnet 160 is arranged on the outer tank cover 100 side, and the adsorption fitting 320 is arranged on the handle 300 side. However, as shown in FIG. 8(b), the adsorption fitting 170 may be arranged on the outer tank cover 100 side and the magnet 340 may be arranged on the handle 300 side. In this case, the lower end surface of the magnet 340 serves as the handle side attraction surface 341 and the upper surface of the attraction fitting 170 serves as the outer tank side attraction surface 171 .

Furthermore, in the above embodiment, an example in which the present invention is applied to the fully automatic washing and drying machine 1 equipped with a clothes drying function is shown. However, the present invention can also be applied to a fully automatic washing machine that is not equipped with a clothes drying function as long as the outer tub cover 23 that covers the inner inlet 101 on the upper surface of the outer tub 20 is provided.
