Description

  In the present invention, a rotating drum formed in a bottomed cylindrical shape is installed in a water tub so that the rotation axis direction is inclined downward from the horizontal direction from the opening front side toward the back side as the bottom, and washing is performed. Related to a drum-type washing machine capable of performing at least one of a washing process, a rinsing process, and a dewatering process by opening an opening / closing lid provided at the front of the machine casing, storing the laundry in a rotating drum, and driving the rotating drum with a motor It is.

  In such a drum type washing machine, an opening / closing lid and a front surface portion of a washing machine casing are inclined at an angle different from the opening end of the rotating drum (for example, see Patent Document 1). In this case, the rotating drum must be symmetrical around the rotation axis because of its rotational characteristics, and the opening end is inclined at right angles to the rotation axis, whereas the opening / closing lid is different from the opening end of the rotating drum. By setting the angle of inclination, the opening of the opening / closing lid and the lower part of the front part of the washing machine casing according to the inclination of the opening end of the rotating drum is suppressed, and the opening / closing lid is not subject to its own weight in the closing direction. It is going to decrease. On the other hand, the drum-type washing machine described in Patent Document 1 has a tapered shape in a side view according to the difference in inclination angle to seal between an opening / closing lid inclined at different angles and an opening end of the water tank. An annular window packing having a side-view shape corresponding to the interval is used.

JP 2000-342880 A

  By the way, the rotating drum easily performs a so-called sliding motion in which the opening end side swings around the cantilevered bearing portion toward the rear of the water tub mainly due to the side of the laundry when dehydrating at high speed. In the water tank floatingly supported by the suspension mechanism under the influence of the movement of the rotating drum, the swinging movement that moves to the swinging side of the rotating drum continues in the circumferential direction. Such swinging of the rotating drum and the swinging motion of the water tank are strong and vibrational, and the swing amount is maximum at the open end. The large and strong swinging movement of the opening end of this water tank is transmitted to the annular window packing that seals between the opening and closing lid, while compressing the packing and stopping the radial deformation force in the circumferential direction between the stopped opening and closing lid. It will be given in a complex manner.

  For this reason, like the annular window packing described in Patent Document 1, when the sectional shape is tapered in side view and the volume of each sectional portion is not identical in the circumferential direction, the above-described vibrational external force is received. Various deformations, restorations, stresses, and inertias that sometimes occur are non-uniform, and the load is amplified and concentrated in a large volume local area, causing early damage and early breakage.

  The main object of the present invention is to provide a cross-section and volume in the circumferential direction between the open / close lid and the open end of the water tank under the condition that the open / close lid in the closed state and the open end of the rotary drum are inclined at different angles. It is an object of the present invention to provide a drum type washing machine that can be sealed by an annular window packing that is substantially uniform and durable.

In order to achieve the above object, a drum-type washing machine according to the present invention has a rotating drum formed in a bottomed cylindrical shape with a rotation axis direction downward from the horizontal direction from the front side to the bottom side toward the back side as the bottom. It is installed in the water tank so as to be inclined, the opening and closing lid provided at the front part of the washing machine casing is opened, the laundry is accommodated in the rotating drum, and the rotating drum is driven by the motor to perform the washing process, the rinsing process, In the drum-type washing machine capable of performing at least one of the dewatering steps, the front surface of the washing machine casing is formed substantially vertically, and the opening / closing lid is closed, and the opening end of the rotating drum is perpendicular to the rotating shaft of the rotating drum. When provided so as to be inclined at an angle between the vertical plane, the open end of the tub, at substantially parallel inclined lid closed the protruding to the front side from the opening end of the rotary drum These opening and closing lids and Between the open end of the tank as before trailing each other to seal in substantially parallel annular windows packing, said water tank is substantially parallel to the inner diameter side and the opening end of the rotary drum to the front side of the body portion A stepped wall formed in the circumferential direction from the shoulder to a position substantially parallel to the closed opening / closing lid, and a step formed in the circumferential step formed by the shoulder and the rising wall. It is characterized in that a bulky weight that fits within the range is attached .

In such a configuration, the opening / closing lid is closed after the laundry is accommodated in the rotating drum, so that the rotating drum is rotated to perform at least one of the washing process, the rinsing process, and the dehydrating process. Leakage of water, splashes of dehydration and the like is prevented between the annular window packing which seals between the open end of the water tank. This closed opening / closing lid is inclined at a different angle from the opening end of the rotating drum, and has an inclination so that the inside of the rotating drum has a sufficient inclination suitable for taking in and out laundry, washing, rinsing and dehydration. It is possible to suppress the inclination while preventing the see-through from the outside and the loading and unloading of the laundry with respect to the rotating drum through the loading / unloading opening provided with the opening / closing lid. In addition, while the opening and closing lid and the opening end of the rotating drum have a difference in the inclination angle as described above, the opening end of the water tank has an inclination parallel to the opening and closing lid, and an annular shape in which the front and rear ends are parallel between them. Since the sealing can be performed by the window packing, the window packing may have a uniform cross-sectional shape and volume of each cross-sectional portion in the circumferential direction .

In addition to the above SL, further closing lid, it is inclined at an angle between the opening end and the vertical surface of the rotating drum, together to suppress the angular difference between the opening end of the rotary drum of the lid In addition, it is possible to suppress the angle difference from the substantially vertical front surface of the washing machine casing, and to suppress the amount of protrusion or depression to the front surface of the vertical washing machine casing .

In addition to the above SL, further rotation of rotating aquarium covers the necessary front region of the body portion side of the substantially parallel rotating by providing a shoulder facing radially inward drum and the open end of the rotary drum barrel front portion While ensuring the safety of the drum from the outside, the opening end of the aquarium is made substantially parallel to the open / close lid by the rising wall having a different height in the circumferential direction from the shoulder portion, and the window packing having the parallel front and rear ends is connected to the open / close lid. It can be supported at the backup position necessary for sealing .

In addition to the above SL, furthermore, the weight is used to attenuate and distribute the vibration energy by receiving the vibration of the water tank, a large front end of the most movement of the tank, and the rising walls forms with said shoulder portion By providing the circumferential stepped portion, the vibration suppression efficiency can be enhanced, and the weight can be accommodated within the stepped portion, so that the weight can be vibrated while deforming the window packing together with the water tank. Interference with the window packing can also be avoided by relative movement. In particular, in the portion where the step becomes large, the weight of the weight provided there is increased corresponding to the step so that there is no problem and the weight with respect to the unit length in the circumferential direction can be increased.

  In the above, further, the gap between the opening end of the water tank and the opening end of the rotating drum is covered with an annular covering member having a side view width corresponding to the difference in inclination angle. it can.

  In such a configuration, in addition to the above, the annular covering member that covers the gap between the opening end of the water tank and the opening end of the rotating drum has a side view width corresponding to the angular difference between the opening ends of the water tank and the rotating drum. And having a tapered shape when viewed from the side, the gap between the opening ends of the water tank and the rotating drum can be covered without being over and under the gap formed by the angle difference.

  According to the drum type washing machine of the present invention, the gap between the opening / closing lid inclined at an angle different from the opening end of the rotating drum and the opening end of the water tank containing the rotating drum is sealed to provide washing water and rinsing water. The annular window packing that prevents the splashes of dehydration from leaking to the outside makes the opening and closing lid and the opening end of the water tank substantially parallel, so that the seal can be made in a form in which the front and rear ends are substantially parallel to each other. The window packing has a uniform cross-sectional shape and volume of each cross-section in the circumferential direction, so the pressure and deformation force are displaced in the circumferential direction between the open end of the swinging water tank and the open / close lid that is stopped. The load when repeatedly receiving the load is equalized in the circumferential direction and is not amplified and concentrated in the local area, and the life can be extended without being damaged or broken at an early stage.

  In addition to the above, the opening / closing lid is inclined at an angle between the opening end of the rotating drum and the vertical surface, so that the opening / closing lid has a sufficient inclination suitable for taking in and out laundry, washing, rinsing and dehydration. It is convenient to use because the inclination can be suppressed while making the see-through from the inside of the rotating drum, and putting the laundry in and out of the rotating drum through the opening / closing opening provided with an open / close lid not particularly inconvenient.

  In addition to the above, the opening / closing lid is inclined at an angle between the opening end of the rotating drum and the vertical surface, and the angle difference from the opening end of the rotating drum and the angle with the substantially vertical front surface of the washing machine housing The difference is suppressed together, and the latter reduces the amount of protrusion or depression to the front of the vertical washing machine housing, and thus to the vertical front, including furniture that is built in so that the front of the washing machine housing is aligned. Appearance is improved.

  In addition to the above, the water tank rotates by covering the necessary front area on the body side of the rotating drum substantially parallel to the opening end of the rotating drum with no waste space by the shoulder facing the inner diameter side on the body front side. For the safety of the drum from the outside, the rising wall with different height in the circumferential direction from the shoulder part makes the opening end almost parallel to the opening / closing lid, and the window packing whose front and rear ends are parallel to seal the opening / closing lid A sufficient seal can be secured by the window packing with the minimum necessary volume supported at the required backup position.

  In addition to the above, while the weight is provided at the circumferential step formed by the shoulder with the largest movement of the water tank and the rising wall to increase the vibration suppression efficiency, the weight is vibrated with the water tank as a bulk that fits within the step. When moving relative to the window packing, it does not interfere with the window packing and damage it. In particular, at the portion where the level difference becomes large, the weight of the weight provided there is increased corresponding to the level difference to increase the weight per unit length in the circumferential direction without any problem, and the vibration suppressing effect can be enhanced.

  In addition to the above, an annular covering member that covers the gap between the opening end of the water tank and the opening end of the rotating drum has a tapered shape in side view, and the opening end of the water tank and the rotating drum is tapered in the side view due to the angle difference. Since the formed gap is closed and covered without excess or deficiency, the laundry can be prevented from being sandwiched between the opening ends of the water tub and the rotating drum without waste in the material of the covering member.

It is the perspective view which removed and showed the weight in the state which attached the window packing to the opening end of the water tank of the drum type washing machine.

  Hereinafter, a drum type washing machine according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 for understanding of the present invention. In addition, the following description is a specific example of this invention, Comprising: The content of description of a claim is not limited.

  As shown in FIG. 1, the drum-type washing machine 1 of the present embodiment shown in FIGS. 1 and 2 has a rotating drum 2 formed in a bottomed cylindrical shape from the opening front side to the back side as the bottom. The rotating shaft 20 is inclined in the downward direction from the horizontal direction so that the rotating shaft 20 is installed in the water tank 3 that is floatingly supported by the suspension, and the opening / closing lid 5 provided at the front part of the washing machine casing 4 is opened to open the laundry. Is stored in the rotating drum 2 and the rotating drum 2 is driven by the motor 6 so that at least one of a washing process, a rinsing process, and a dehydrating process can be performed. As shown in FIGS. 1 to 3, the opening / closing lid 5 is applied to a lid body 8 having a window 7 fitted with a transparent glass plate 11 through which the laundry is seen from the outside, and the front surface of the lid body 8. The lid cover 9 is made transparent so that the necessary fluoroscopic area leaving the front area or the periphery is left. The lid body 8 has a lid frame 8a molded from polypropylene, a back frame 8b molded from polypropylene having higher chemical resistance, and a glass plate 11 sandwiched between its peripheral portions, and a screw 66 as shown in FIG. It is fixed. The lid cover 9 is formed of transparent ABS.

By the way, in the drum type washing machine 1 of the present embodiment, the closed open / close lid 5 is as shown in FIG.
Inclined to the rear side at an angle different from the opening end 2a of the rotary drum 2, and thus in a rearwardly inclined relationship, and the opening / closing lid 5 has an inclination, sufficient inclination suitable for taking in and out laundry, washing, rinsing and dewatering Therefore, it is possible to prevent inconvenience from seeing from the outside of the rotating drum 2 provided with the knives, and putting the laundry in and out of the rotating drum 2 through the loading / unloading opening 12 provided in the opening / closing lid 5. Therefore, the annular lid packing 13 that seals between the open end 3a of the water tank 3 and the closed opening / closing lid 5 is tapered in a side view and has a sectional shape like the annular window packing described in Patent Document 1. If the volume of each cross-section becomes uneven in the circumferential direction, the load when receiving an external vibration force that becomes particularly large at the opening end 3a of the water tank 3 is amplified and concentrated in a local area with a large volume, resulting in early damage. Causes premature breakage.

  To cope with this, the opening / closing lid 5 and the opening end 3a of the water tank 3 can be sealed with an annular window packing 13 having a substantially uniform cross section and volume in the circumferential direction and having excellent durability. With the lid 5 in the closed state, as shown in FIG. 1, the opening end 3 a of the water tank 3 is in contact with the rotating drum 2 in a relationship inclined at a different angle from the opening end 2 a perpendicular to the rotating shaft 20 of the rotating drum 2. The front and rear ends 13a, 13b are substantially parallel to each other between the opening / closing lid 5 and the opening end 3a of the water tank 3 so as to face the opening / closing lid 5 which projects to the front side of the opening end 2a and is closed. Sealing is performed with an annular window packing 13. Thus, the opening / closing lid 5 is closed after the laundry is accommodated in the rotating drum 2, and the rotating drum 2 is rotated to perform at least one of a washing process, a rinsing process, and a dehydrating process. It is possible to prevent leakage of water, dewatering splashes, and the like between the annular window packing 13 that seals between the opening end 3 a of the water tank 3. Further, while the opening / closing lid 5 and the opening end 2a of the rotating drum 2 have the above-described characteristics depending on the inclination angle, the opening end 3a of the water tank 3 has an inclination parallel to the opening / closing lid 5 and is between them. Are sealed by the annular window packing 13 with the front and rear ends 13a and 13b parallel to each other. Therefore, the window packing 13 may have a uniform cross-sectional shape and a volume of each cross-sectional portion in the circumferential direction.

  As a result, the gap between the opening / closing lid 5 that is inclined at a different angle from the opening end 2a of the rotating drum 2 and the opening end 3a of the water tank 3 housing the rotating drum 2 is sealed, so that washing water, rinsing water, dehydration The annular window packing 13 that prevents the splashes of the water from leaking outside makes the opening / closing lid 5 and the opening end 3a of the water tank 3 substantially parallel to each other so that the front and rear ends 13a and 13b are substantially parallel to each other. The window packing 13 has the same cross-sectional shape and volume in each cross-section in the circumferential direction, so that the opening end 3a of the swinging water tank 3 and the open / close lid 5 that is stopped The load when repeatedly receiving compression and deformation forces with circumferential displacement is equalized in the circumferential direction and does not concentrate and concentrate locally, resulting in long life without damage or breakage at an early stage. .

  Here, the front and rear ends 13 a and 13 b mean a pressure contact end with the opening / closing lid 5 and a mounting end to the opening end 3 a of the water tank 3, and the rear end 13 b is elastic to the annular recess 3 b on the outer periphery of the opening end 3 a of the water tank 3. The mounting seat portion 13b1 seated on the front surface of the inward flange 3c on the front surface side of the recess 3b is formed, and the front end 13a is crimped to the continuous annular surface 5a on the inner peripheral side of the back surface of the lid body 8 of the opening / closing lid 5. A sealing lip 13a2 that closely fits to the inner periphery of the window 7 of the lid lip 13a1 and the lid body 8 is formed in a bifurcated shape having a substantially right-angle cross section. The lid packing 13 as a whole is connected to the mounting seat 13b1 in the form in which the center portion in the width direction of the flange 3c and the bifurcated connecting portion of the seal lips 13a1 and 13a2 are connected by the connecting portion 13c. 13c uses the fact that the connecting diameter to the bifurcated connecting portion is reduced with respect to the rising diameter of the mounting seat portion 13b1, and forms an M-shaped cross section from the mounting seat portion 13b1 slightly obliquely outward toward the front side. The M-shaped portion 13c1 with one leg raised so as to be folded back to the front side from the other end of the M-shaped portion 13c1 on the non-rise side, and the sealing lip 13a2 is connected to the bifurcated connecting portion of the opening / closing lid 5 A sealing pressure required for the lid packing 13 between the closed opening / closing lid 5 and the flange 3c at the opening end 3a of the water tub 3 is assumed to have a folded portion 13c2 connected in parallel with the axis 14. The M-shaped portion 13c1 swings with the opening end 3a of the aquarium 3 at the rear end 13b attached to the opening end 3a of the aquarium 3 with respect to the front end 13a2 side pressed against the stationary opening / closing lid 5. In particular, it is designed to work as an elastic buffer that can be flexibly adapted.

  As shown in FIG. 1, the opening / closing lid 5 is inclined at an angle between the opening end 2a of the rotating drum 2 and the vertical surface. It is assumed that they are formed almost vertically. Thereby, the angle difference between the opening end 2a of the opening / closing lid 5 and the opening end 2a of the rotating drum 2 can be suppressed because the opening / closing lid 5 is inclined at an angle between the opening end 2a of the rotating drum 2 and the vertical plane. In addition, the angle difference from the substantially vertical front surface 4a of the washing machine casing 4 can be suppressed, and the amount of protrusion or depression to the vertical washing machine casing front surface 4a can be suppressed. This is because the washing machine housing 4 is built-in so that the fronts are aligned with each other, and the amount of protrusions and depressions due to the inclination with respect to the vertical front surface including various furniture 14 as shown in phantom lines in FIG. 1 is suppressed. Therefore, the appearance of both furniture and equipment is improved.

  In the illustrated example, the water tank 3 has a shoulder portion 32 facing the inner diameter side substantially parallel to the opening end 2 a of the rotating drum 2 on the front side of the trunk portion 31, and is opened and closed closed from the shoulder portion 32. An opening end 3 a is formed having a rising wall 33 with different heights in the circumferential direction to a position substantially parallel to the lid 5, and a rear end portion 13 b of the window packing 13 is attached to the rising end portion of the rising wall 33. Yes. As a result, the water tank 3 is provided with a shoulder portion 32 facing the inner diameter side substantially parallel to the opening end 2a of the rotating drum 2 on the front side of the body portion 31 to cover the necessary front region on the body portion 21 side of the rotating drum 2. Front and rear ends 13a, with the opening end 3a of the water tank 3 being substantially parallel to the opening / closing lid 5 by the rising wall 33 having a different height in the circumferential direction from the shoulder portion 32, while ensuring safety from the outside with respect to the rotating drum 2 that rotates. The back-up position required for sealing the window packing 13 parallel to 13b with the opening / closing lid 5 can be satisfactorily supported by the form having the M-shaped portion 13c, etc., and the minimum volume is required. A sufficient seal can be secured by the window packing 13.

  Furthermore, a weight 15 having a bulk which is substantially within the step range is provided on the circumferential step 34 formed by the shoulder 32 and the rising wall 33, as shown in FIGS. These are attached to the plurality of boss portions 32a shown in FIG. Such a weight 15 is used for receiving vibration of the water tank 3 and dispersing and attenuating the vibration energy, but the shoulder part 32 and the rising wall 33 which become the front end part 3a with the largest movement of the water tank 3 As a result, the vibration suppression efficiency can be increased. Further, since the weight 15 has a bulk that can be substantially accommodated in the stepped portion 34, the window packing is also caused by relative movement with the window packing 13 when the weight 15 is moved with the water tank 3 while deforming the window packing 13. 13 can be avoided, and the window packing 13 is not damaged. In particular, in the upper part where the level difference of the level difference part 34 is large, the weight of the weight 15 provided there is increased corresponding to the level difference to increase the weight with respect to the unit length in the circumferential direction without any problem, and the vibration suppressing effect can be enhanced. . Through the water injection pipe 30 shown in FIGS. 1 and 7, which is piped to avoid the boss portion 32 a of the shoulder portion 32 to which the weight 15 is attached from the outside of the water tank 3 through the inside of the shoulder portion 32 of the water tank 3 provided with the weight 15. 1 is sprayed into the rotary drum 2 through the water injection port 40 of the cover member 17 shown in FIG. 1 so as to effectively inject water into the laundry, particularly clothes.

  Further, the gap between the opening end 3a of the water tank 3 and the opening end 2a of the rotating drum 2 is covered with an annular covering member 17 having a side view width corresponding to the difference in inclination angle. Thereby, the annular covering member 17 covering the gap S between the opening end 3a of the water tank 3 and the opening end 2a of the rotating drum 2 is a side face corresponding to the angular difference between the opening ends 2a and 3a of the water tank 3 and the rotating drum 2. By having a viewing width and a side view taper shape, the gap between the water tank 3 and the open ends 2a and 3a of the rotary drum 2 formed in a side view taper shape by the angle difference is completely closed. The covering material 17 can be covered and the laundry can be prevented from being caught between the water tank 3 and the open ends 2a and 3a of the rotating drum 2 without waste.

  In addition, it has the shoulder part 22 which faces the internal diameter side in the front part of the trunk | drum 21 of the rotating drum 2, and forms the opening end of a smaller diameter than the trunk | drum 21, The water depth required for washing and rinsing can be ensured. On the other hand, the shoulder 32 of the water tank 3 is opposed to the opening end 2a of the rotating drum 2 with a certain gap in the inner week of the flange 3c extending from the rising end of the rising wall 33 toward the inner diameter side. A part having the inner peripheral wall 35 is an open end 3a constituting a double peripheral wall. Thereby, it is avoided that the gap width between the open ends 2a and 3a differs in the circumferential direction and becomes a large gap width depending on the place. Further, the front end of the covering member 17 slightly protrudes toward the front side of the opening end 3 a near the inner periphery of the opening end 3 a of the water tank 3, and the inner periphery of the opening end 3 a of the water tank 3 extends to the opening end 2 a of the rotating drum 2. The inner diameter of the covering portion is made smaller than the inner diameter of the opening end 2a of the rotary drum 2. The cover member 17 is screwed to a boss portion 32 a formed on the inner surface of the shoulder portion 32 of the water tank 3 with a screw 18.

  More specifically, the slot 12 is formed in a metal body panel 41 that forms a range excluding the upper and lower portions of the front surface 4a of the washing machine casing 4 as shown in FIGS. When the body panel 41 is molded from a single plate, as described above, when the opening / closing lid 5 is inclined with respect to the substantially vertical front surface 4a, the opening / closing lid 5 closes and closes the entrance / exit 12 and The annular area 42 as shown in FIG. 1 and FIG. 6 is a concave bottom part that penetrates deeply from the front surface 4a formed by the body panel 41 as shown in FIG. It becomes the drawing part. Then, it is difficult to form the body panel 41 having a thickness that satisfies the strength required to support the washing machine casing 4 and the opening / closing lid 5 and the cost becomes high. To cope with this, in the present embodiment, the body panel 41 is divided and formed into an annular body panel 41b corresponding to the annular region 42 and a peripheral frame-shaped body panel 41a. I am doing so. Thereby, the body panel 41 is obtained by a combination of the body panels 41a and 41b that can be processed easily and at a low cost by reducing the drawing degree by half.

  The body panels 41a and 41b can be integrated in various ways such as welding, caulking, tacking, and screwing. In the illustrated example, the body panels 41a and 41b are integrated at a spot weld 43. For this integration, the annular body panel 41b is formed with an annular bulging portion 41b1 facing the rear side so as to be in pressure contact with the lid packing 15 on the inner periphery with a groove formed on the front side, and this annular bulging portion. The outer peripheral wall 41b2 that has a large curved surface on the upper side and is bent and rises on the lower side after extending flat from the periphery to the periphery, and has an outward flange portion 41b3 formed at the front end of the outer peripheral wall 41b2. The body panel 41a is formed with a concave peripheral wall 41a1 corresponding to the outer peripheral portion of the annular region 42 in the front surface 4a formation region of the washing machine casing 4, and is applied to the flange portion 41b3 from the rear at the rear edge of the concave peripheral wall 41a1. It is assumed that an inward flange portion 41a2 is formed, and spot welding at a plurality of locations in the circumferential direction indicated by the spot welded portion 43 is an overlapping portion of the flange portions 41a3 and 41a2. So that is subjected to.

  Here, the hinge unit 51 shown in FIG. 6 is attached to the left and right sides of the annular body panel 41b by a fastening screw 52 from the front side so that the opening / closing lid 5 can be opened and closed by the hinge unit 51. 3, a lid lock portion 53 with a lid closing detection switch that receives and locks the engagement piece 5a of the opening / closing lid 5 shown in FIG. 3 in the lock window 53a and locks the opening / closing lid 5 in the closed state. The lid opening button 54 for releasing the lock is screwed from the front side by applying screws 55 and 56, respectively. The hinge unit 51 may be known from Japanese Patent Laid-Open No. 2005-143794, and the lid lock portion 53 and the lid opening button 54 may be known from Japanese Patent Laid-Open No. 2005-137508.

  Further, as shown in FIG. 6, the frame-shaped body panel 41a is a shallow box type in which the rectangular part forming the front surface 4a of the washing machine casing 4 has a peripheral wall 41a3, and an annular recess is formed in the upper part of the box type. The peripheral wall 41a2 has a shape in which the annular region 42 is rounded to the width of the annular region 42, the annular body panel 41b is thick, and the frame body panel 41a is a combination of thin plate thicknesses. The overlap spot welding structure and the three-dimensional shape are combined to satisfy the required strength, and the washing machine housing 4 is reduced in weight and cost by the amount that the body panel 41a having a large area can be thinned.

  Further, the annular region 42 equipped with the hinge unit 51, the lid lock portion 53 and the lid opening button 54 of the body panel 41 is a resin-made annular cover panel 44 except for the lid opening button 54 as shown in FIG. As shown in FIGS. 1 and 3, the cover panel 44 is screwed to the annular body panel 41b at a plurality of locations in the circumferential direction by screws 45 as shown in FIGS. As a result, when the cover panel 44 is removed to the front side, the hinge unit 51, the lid lock portion 53, and the lid opening button 54 provided on the body panel 41 are exposed, so that repair and replacement maintenance thereof can be performed.

  Further, the front surface 4a of the washing machine casing 4 is formed of a resin panel that covers the body panel 41a, a resin top mark unit 58 that covers the upper portion of the body panel 41a and the top plate 57, and a lower portion of the body panel 41a. The top mark unit 58 is formed of a panel 59, and has an operation surface on which a start / stop switch key 61, a setting operation unit 62 for various modes, a liquid crystal display unit 63, a display lamp, and the like are arranged. Here, the cover panel 44 and the top mark unit 58 are both resin molded products, and the opposing surfaces 44a and 58a that are adjacent to each other in the vertical direction can be formed so as to continue at a right angle to the surface. As shown in FIG. As a result, the resin surface inclined to the rear side toward the center side in a shape where the upper portion bites into the horizontally long resin surface forming the upper portion of the front surface 4a of the washing machine casing 4 is continuous with different colors without any gaps. The surface 44b, 58b of the continuous cover panel 44 and the top mark unit 58 facing the metal body panel 41a made of different materials, together with the facing surface 59a of the opening / closing panel 59, has a body panel. 41a3 is adjacent to the side peripheral wall 41a3 and the concave peripheral wall 41a1, but the rounded corners by bending the side peripheral wall 41a3 and the concave peripheral wall 41a1 form a butt portion that forms a gap, Appearance composition that emphasizes existence and independence is realized.

  The butting of the cover panel 44 and the top mark unit 58 is realized by the top mark unit 58 covering the front end of the recessed peripheral wall 41a2 of the body panel 41a. In addition, this covering structure is realized by attaching the top mark unit 58 to the upper portion of the body panel 41a from the front side and covering the front end of the side peripheral wall 41a3 of the body panel 41a. Therefore, the body panel 41a cannot be removed unless the top mark unit 58 is prioritized. Correspondingly, the top mark unit 58 is fitted with upper and lower walls 58a, 58a from the front part between the side peripheral wall 41a3 of the body panel 41a and the fixed wall 64 on the washing machine housing 4 side provided on the outer side thereof. A check protrusion 58c formed outwardly on 58a and 58a is elastically engaged with a locking hole 65 formed in the side peripheral wall 41a3 and the fixed wall 64 by utilizing the elasticity of the upper and lower walls 58a and 58b, thereby preventing the protrusions 58c. In addition, the body panel 41a can be easily removed by the detaching force that overcomes the pull-out force.

  In a drum-type washing machine installed with an inclined rotating drum, lid packing that seals between the opening and closing lid and the opening end of the aquarium even if the opening end of the rotating drum and the opening and closing lid are inclined at different angles The front and rear ends thereof are parallel, the cross section and the cross section volume are substantially uniform in the circumferential direction, and the durability can be high.
