It should be explained that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but are intended to explain the concept of the present invention to those skilled in the art with reference to specific embodiments. It is a thing.

In order to further clarify the purpose, technical plan and advantages of the examples in the present invention, the technical plan of the examples will be described clearly and concisely below. The following examples are for explaining the present invention and do not limit the scope of the present invention.

As shown in FIGS. 1 to 12, in this embodiment, the outer tub 1, the drainage device 4 for discharging the water inside the outer tub 1 to the outside of the washing machine, and the bubbles overflowing from the inside of the outer tub 1 are included. Disclosed is a wall-mounted washing machine including an overflow pipe 51 that discharges water to the outside of the washing machine. The drainage device 4 communicates with the drain valve assembly 41 that communicates with the outer tub 1 to forcibly discharge the water in the outer tub 1, and communicates with the drain valve assembly 41 to wash the water discharged from the drain valve assembly 41. It includes a drainage pipe 42 for discharging to the outside of the machine, and a mounting structure 43 for fixing and supporting the drainage pipe 42 and the overflow pipe 51 at one end near the wall in the outer tank 1.

In the above plan, the wall-mounted washing machine is different from a normal drum washing machine in that it is installed on one flat surface. A wall-mounted washing machine is a washing machine that is used by hanging it on the wall. The wall-mounted washing machine of the present invention includes a drainage device 4. The drainage device 4 includes a drain valve assembly 41 that forcibly discharges the water in the outer tank 1 from the inside of the outer tank 1 to the outside at an appropriate cleaning stage, and the water forcibly discharged from the outer tank 1 is included. Is discharged to the outside of the washing machine via the drain pipe 42. Generally, of the drain pipes 42, it is the hose that finally discharges water to the outside of the washing machine, and damage due to vibration, collision, or the like is likely to occur. Further, the wall-mounted washing machine generally includes a ventilation device 5, and realizes the flow of air between the inside and the outside of the outer tub 1 to prevent the danger of the outer tub 1 bursting due to the inability to ventilate. The ventilation device 5 includes an overflow pipe 51. That is, the bubbles and water overflowing from the inside of the outer tub 1 can be discharged to the outside of the washing machine, and the inside of the outer tub 1 can be ventilated. The drain hose of a normal wall-mounted washing machine penetrates the back plate and then extends to the outside of the washing machine. In this case, the fixing action is achieved by penetrating the back plate, but the damage rate of the hose increases because the sharp edges and rib structures that may exist at the edges of the holes on the back plate damage the hose when the hose vibrates. It gets higher. Moreover, when the overflow pipe 51 directly communicates with the drain pipe 42, since the drain pipe 42 is a hose, there is a tendency that there is a risk of falling out due to leakage or wobbling. The drainage device 4 of the wall-mounted washing machine described in the present invention further includes a mounting structure 43 for mounting and fixing the drainage pipe 42 and the overflow pipe 51 in order to solve such a problem. The mounting structure 43 fixes and supports the drain pipe 42 and the overflow pipe 51 at one end of the outer tank 1 near the wall, and draws water to the rear side of the outer tank 1 to smoothly discharge the water. As a result, the appearance is poor due to the exposure of the drain pipe 42 that occurs when the drain pipe 42 is installed at the front end of the outer tank 1, and it is impossible to fix the drain hose in the connection process between the floor drain port. Prevents damage to the drain hose due to wobbling and vibration. Further, by installing the mounting structure 43, it is possible to prevent the drain pipe 42 and the overflow pipe 51 from being damaged due to wobbling or vibration during drainage.

Further, a base is provided at one end of the outer tub 1 of the washing machine near the wall, and the drain pipe 42 and the overflow pipe 51 are fixed and supported on the base via the mounting structure 43.

Further, the tank wall of the outer tank 1 is provided with at least one suspension ear 2 projecting outward in the radial direction. The suspension ear 2 is closely and fixedly connected to the wall surface. The drainage pipe 42 and the overflow pipe 51 are fixed and supported by the suspension ear 2 via the mounting structure 43.

Preferably, suspension ears 2 are provided at each of the four corners of the tank wall of the outer tub 1, and the drainage pipe 42 and the overflow pipe 51 are attached to the lower 1 of the outer tub 1 via the mounting structure 43. It is fixed and supported by one suspension ear 2.

More preferably, the drain pipe 42 and the overflow pipe 51 are fixed and supported by one suspension ear 2 near the drain valve assembly 41 on the lower side of the outer tank 1 via the mounting structure 43.

In the above plan, the base is installed. The base is a medium that not only does not occupy the space at one end of the outer tub 1 near the wall, but is also mounted so that the mounting structure 43 can be easily fixed and supported at one end of the outer tub 1 near the wall. Also, if you try to mount it directly on the wall, both cost and operation difficulty will increase, so we have installed a base. As one embodiment, the base may be at least one suspension ear 2 installed on the tank wall of the outer tank 1 and protruding outward in the radial direction, or the base and the suspension ear 2 may be used as separate means. good. The outer tank 1 of the present invention is suspended on the wall surface via the suspension ear 2, and does not need to be supported by a member such as a damper. As a result, the number of members of the washing machine is reduced, so that the production cost and the difficulty of assembling the washing machine are further reduced. Moreover, since the size and weight of the entire washing machine are reduced, the appearance of the washing machine is optimized and the reliability of the wall hanging of the washing machine is improved. Further, the drainage pipe 42 and the overflow pipe 51 are fixed and supported by the suspension ear 2 via the mounting structure 43. As a result, the drainage pipe 42 and the overflow pipe 51 are installed on the rear side of the outer tank 1 and are fixed on the suspension ear 2, so that the drainage pipe 42 due to the fact that the back plate in the present invention is not installed. The problem that the problem cannot be fixed is prevented. Therefore, problems such as wobbling, vibration, breakage, and water scattering caused by the inability to fix the drain pipe 42 can be avoided. The drainage pipe 42 is detachably installed on the suspension ear 2 via the mounting structure 43 so that the drainage pipe 42 can be easily attached, repaired, inspected, replaced, and the like. Suspension ears 2 are provided at each of the four corners of the tank wall of the outer tank 1. In a preferred embodiment, the suspension ears 2 are provided on two height surfaces. Further, the wall surface is provided with a support member 3 extending in the direction of the outer tank 1. The support member 3 is inserted into the suspension ear 2 and abuts on the suspension ear 2 to support it. As a specific assembling step of the outer tank 1 in the present invention, the support member 3 is first mounted on the wall surface, and then the suspension ear 2 is suspended on the support member 3 to temporarily fix the outer tank 1. Finally, the nut is turned to the support member 3 inserted through the suspension ear 2, and the suspension ear 2 is sandwiched and fixed on the support member 3 between the wall surface and the nut. As a result, the assembly of the outer tank 1 is realized. In a preferred embodiment, the vibration control pad is sandwiched and fixed between the wall surface and the suspension ear 2 and between the suspension ear 2 and the nut, respectively, to reduce the noise generated in the washing machine during the operation process. Further, the suspension ear 2 may be fixedly connected to the wall surface by a bolt, and the suspension ear 2 may be sandwiched and fixed to a bolt screw portion between the nut of the bolt and the wall surface. In a preferred embodiment, the vibration control pad is sandwiched and fixed between the wall surface and the suspension ear 2, and between the suspension ear 2 and the nut of the bolt, thereby reducing the noise generated in the washing machine during the operation process. The drainage pipe 42 and the overflow pipe 51 in the present invention are installed in one suspension ear 2 on the lower side of the outer tank 1 via the mounting structure 43. As a result, the water is installed on the rear side of the outer tank 1 and on the lower side of the outer tank 1, so that the water is discharged without remaining more easily due to the action of gravity. Further, the drainage pipe 42 and the overflow pipe 51 are fixedly installed while guaranteeing the appearance. In a preferred embodiment, the drainage pipe 42 and the overflow pipe 51 are installed in one suspension ear 2 near the drainage valve assembly 41 on the lower side of the outer tank 1 via the mounting structure 43. As a result, the device is simplified, and the installation method and structure of the drain pipe 42 by the mounting structure 43 are also simplified.

Further, the rear wall of the outer tank 1 is provided with an exhaust hole 53 that communicates with the inside of the outer tank 1. The overflow pipe 51 is installed at the rear of the outer tank 1, one end of which communicates with the inside of the outer tank 1 through the exhaust hole 53, and the other end of which communicates with the drainage device 4.

Preferably, one end of the overflow pipe 51 communicates with the highest water level inside the outer tank 1 through the exhaust hole 53, and the other end is fixed and supported at one end near the wall in the outer tank 1 via the mounting structure 43. Ru.

In the above plan, since the overflow pipe 51 is installed at the rear of the outer tub 1, the side space of the outer tub 1 is saved as compared with the case where it is installed at the side of the outer tub 1, and the wall-mounted washing is performed. The volume of the machine becomes smaller. Moreover, since the overflow pipe 51 can be installed between the rib structures of the rear wall of the outer tank 1, it does not occupy a large space on the rear wall of the outer tank 1. The rear wall of the outer tank 1 includes an exhaust hole 53 communicating with the inside of the outer tank 1. Since the exhaust hole 53 is installed on the rear wall of the outer tank 1, the overflow pipe 51 can be easily connected to the rear wall of the outer tank 1. One end of the overflow pipe 51 communicates with an exhaust hole 53 installed above the rear wall of the outer tank 1, and the other end communicates with the drainage device 4, so that bubbles overflowing from above the outer tank 1 And water is discharged to the outside of the washing machine through the drain device 4. In a preferred embodiment, since the overflow pipe 51 communicates with the maximum water level inside the outer tank 1 through the exhaust hole 53, unexpected overflow of bubbles and water generated when the installation position of the exhaust hole 53 is low may occur. , Problems such as not being able to clean cleanly due to this are avoided. Further, the other end of the overflow pipe 51 is fixed and supported at one end near the wall in the outer tank 1 via the mounting structure 43. As a result, the stagnation of drainage that tends to occur when draining through the drainage pipe 42 after the overflow pipe 51 is extended to the front end of the outer tank 1 toward the drain valve assembly 41 at the bottom of the outer tank 1 is prevented. To. Alternatively, when the overflow pipe 51 directly communicates with the drain pipe 42, the drain pipe 42 and the overflow pipe 51 vibrate, respectively, and the connection is loosened to prevent a situation in which an overflow occurs.

Further, the mounting structure 43 has a support portion 432 for supporting the drainage pipe 42 and the overflow pipe 51 at one end near the wall in the outer tank 1, and the drainage pipe 42 and the overflow pipe 51 near the wall in the outer tank 1. Includes a mounting portion 431 for mounting and fixing to one end of the.

Preferably, the mounting portion 431 and the supporting portion 432 are integrally molded.

In the above plan, the support portion 432 supports the drainage pipe 42 and the overflow pipe 51 at one end of the outer tank 1 near the wall. That is, one end of the drain pipe 42 and one end of the overflow pipe 51 on the drain side are supported by one end near the wall in the outer tank 1. By supporting the drainage pipe 42 and the overflow pipe 51 and further supporting the drainage valve assembly 41 to make the mounting more rigid, the drainage pipe 42 and the overflow pipe 51 are wobbled, fallen out, damaged, etc. due to the action of vibration. The danger of is prevented. Normally, the drain valve assembly 41 cannot be installed on the rear side of the outer tank 1 due to elemental limitations such as shape and drain position. Therefore, when the drain pipe 42 is pulled out directly from the drain port of the drain valve assembly 41, the position of the drain pipe 42 is closer to the front, and wobbling is likely to occur. In addition, the appearance is poor, and the drain pipe 42 drawn out from the washing machine cannot be fixed. Therefore, by installing the support portion 432, the drainage pipe 42 and the overflow pipe 51 are supported at one end of the outer tank 1 near the wall. The mounting portion 431 further realizes the purpose of fixing the drainage pipe 42 and the overflow pipe 51 by mounting the drainage pipe 42 and the overflow pipe 51 at one end near the wall in the outer tank 1, and is accompanied by vibration. Prevent danger. In one embodiment, the mounting portion 431, the drain pipe 42, and the overflow pipe 51 are integrally molded. In this case, the cost is saved and the processing and molding becomes easy, but the difficulty at the time of mounting increases. Further, in another embodiment, the mounting portion 431, the drain pipe 42, and the overflow pipe 51 are detachably connected to each other. In this case, it is easy and convenient to put on and take off. In a preferred embodiment, the mounting portion 431 and the supporting portion 432 are integrally molded. Further, the drainage pipe 42 and the overflow pipe 51 are supported by the support portion 432, and are supported at one end of the outer tank 1 near the wall via the mounting portion 431. This structure is simple, easy to mold, easy to install and repair, and saves money.

Further, one end of the support portion 432 communicates with the drain valve assembly 41, and the other end communicates with both the drain pipe 42 and the overflow pipe 51.

In the above plan, one end of the support portion 432 communicates with the drain valve assembly 41 and receives the water discharged from the drain valve assembly 41. Further, the other end and one end of the drain pipe 42 discharge the water discharged from the drain valve assembly 41 to the outside of the washing machine through the drain pipe 42. Further, the other end of the support portion 432 communicates with the other end of the overflow pipe 51. The other end of the overflow pipe 51 communicates with the drain pipe 42 through the support portion 432, and the bubbles and water overflowing from the inside of the outer tub 1 are discharged to the outside of the washing machine through the drain pipe 42.

Further, the support portion 432 has a tubular structure. One end of the tubular structure communicates with the drain valve assembly 41. Further, the other end extends toward one end near the wall in the outer tank 1 and communicates with both the drain pipe 42 and the overflow pipe 51, and the drain pipe 42 and the overflow pipe 51 are close to the wall in the outer tank 1. Support at one end of.

Preferably, the support portion 432 is a rigid pipe and is installed on the same horizontal plane as the drain valve assembly 41.

More preferably, the support portion 432 extends from the drain valve assembly 41 while inclining toward one end near the wall in the outer tank 1. As a result, the communication point between the drain pipe 42 and the support portion 432 is lower than the communication point between the support portion 432 and the drain valve assembly 41.

In the above plan, the support portion 432 has a tubular structure. The tubular structure has a hollow cavity for the flow of water. The drain valve assembly 41, the drain pipe 42, and the overflow pipe 51 communicate with each other through the tubular structure and are installed at both ends of the tubular structure. As a result, the water of the drain valve assembly 41 is guided to the drain pipe 42, and the drain valve assembly 41 is supported. Further, by supporting the drainage pipe 42 and the overflow pipe 51 at one end near the wall in the outer tank 1, the other end of the drainage pipe 42 can be easily extended and fixed. In addition, the overflow pipe 51 realizes communication with the drain pipe 42 through the support portion 432, and discharges the overflowing water and bubbles to the outside of the washing machine. In a preferred embodiment, the support portion 432 is a hard pipe to realize a support action for the drain pipe 42, the overflow pipe 51, and the drain valve assembly 41. On the other hand, in the case of a soft tube, the supporting action cannot be realized. The support portion 432 is installed on the same horizontal plane as the drain valve assembly 41. This structure is simple, does not occupy a large amount of space, and is easy to install and repair. In a more preferred embodiment, the support portion 432 extends from the drain valve assembly 41 while tilting toward one end near the wall in the outer tank 1. As a result, the water in the support portion 432 flows out from the drain pipe 42 without completely remaining, and does not flow back. Further, the bubbles and water discharged from the overflow pipe 51 to the support portion 432 do not flow back. The communication point between the drain pipe 42 and the support portion 432 is lower than the communication point between the support portion 432 and the drain valve assembly 41 because the water in the support portion 432 is discharged better and the water remains or remains. This is to prevent backflow.

Further, the mounting portion 431 includes a mounting plate for mounting and fixing the support portion 432 to one end near the wall in the outer tank 1 so as to be removable. The mounting plate is provided with a mounting through hole 4311, and a screw is inserted through the mounting through hole 4311 to detachably mount and fix the mounting plate to one end near the wall in the outer tank 1.

Preferably, the sides and corners of the mounting plate are gently continuous.

In the above plan, the mounting plate detachably installs the drainage pipe 42 and the overflow pipe 51 on the suspension ear 2 / base. One end surface of the mounting plate is in contact with the support portion 432 and is integrally molded with the support portion 432. Further, the other end surface facing the end surface is in contact with the suspension ear 2 or the base, and is detachably connected to the suspension ear 2 or the base by a screw. In a preferred embodiment, the sides and corners of the mounting plate are gently continuous so that the sharp sides and corners injure the mating corner and other positions or personnel performing the mounting / removal during the mounting / removal process. To prevent.

Further, the mounting unit 431 includes a position regulating unit 4312 that position-regulates the connection of the mounting plate.

Preferably, the position restricting portion 4312 is integrally molded on the side surface of the mounting plate.

More preferably, the position limiting portion 4312 includes a protruding portion that protrudes from the side of the mounting plate and continues to extend.

In the above plan, the position limiting unit 4312 prevents mounting mistakes and movement after mounting by positioning and connecting the mounting plate to the suspension ear 2 or the base. In a preferred embodiment, the position restricting portion 4312 is integrally molded on the side surface of the mounting plate, which saves space. In addition, there is no need to install or connect separately, which saves costs. In a more preferred embodiment, the position limiting section 4312 includes a projecting portion that projects from the side of the mounting plate and continues to extend. Therefore, it is not necessary to install the assembly separately, which saves cost. By installing the protruding part, the effect of position regulation can be achieved only by the shape. The protrusion may have a plate-like structure having a rectangular, trapezoidal, or other polygonal shape.

Further, one end of the overflow pipe 51 is connected to the exhaust hole 53, the other end extends downward along the circumferential direction of the rear wall of the outer tank 1 and is connected to the support portion 432, and the support portion 432 is connected to the support portion 432. It communicates with the drain pipe 42 through.

It is stretched and then horizontally stretched to the support portion 432 and connected to the support portion 432.

In the above plan, the overflow pipe 51 extends downward along the circumferential direction of the rear wall of the outer tank 1, so that the ribs are ribbed without excessively interfering with the rib arrangement on the rear wall of the outer tank 1. It is installed between the rib and the rib. Therefore, it does not occupy space and does not impair the distribution of ribs. In a preferred embodiment, the overflow pipe 51 extends downward along the circumferential direction of the rear wall of the outer tank 1 toward the axis, so that the length of the overflow pipe 51 is shortened, and bubbles and water are more removed. It can be discharged quickly. This avoids the situation where bubbles accumulate and overflow. In addition, the closer to the axis, the greater the vibration received, so that the bubbles are more easily broken and flow out. In a more preferred embodiment, one end of the overflow pipe 51 extends downward by a certain distance in the vertical direction from the exhaust hole 53, and then downwards along the axial direction of the rear wall of the outer tank 1. Stretch. The overflow pipe 51 extending downward in the vertical direction can more easily flow bubbles and water toward the drainage device 4. The other end of the overflow pipe 51 extends downward along the circumferential direction of the rear wall of the outer tank 1, and then extends toward the front of the outer tank 1 toward the front of the outer tank 1 to the same horizontal plane as the support portion 432. Subsequently, it extends horizontally to the support portion 432 and is connected to the support portion 432. This facilitates communication between the overflow pipe 51 and the support portion 432 and does not occupy extra space. The overflow pipe 51 consistently has no space for vibration behind the outer tank 1. Therefore, even if the outer tank 1 is stretched from the rear and then stretched to the connection portion while tilting, no large vibration is generated. Moreover, the rise of bubbles due to the water containing bubbles blocking the connection points is unlikely to occur.

As shown in FIGS. 1 to 12, the present embodiment discloses a wall-mounted washing machine including an outer tub 1 and further including a drainage device 4.

Specifically, the other end of the overflow pipe 51 communicates with the drain pipe 42 through the support portion 432. Normally, the drain valve assembly 41 cannot be installed on the rear side of the outer tank 1 due to elemental limitations such as shape and drain position. Therefore, when the drain pipe 42 is pulled out directly from the drain port of the drain valve assembly 41, the position of the drain pipe 42 is closer to the front, and wobbling is likely to occur. In addition, the appearance is poor, and the drain pipe 42 drawn out from the washing machine cannot be fixed. Therefore, the support portion 432 is installed, and the water forcibly discharged from the drain valve assembly 41 is drawn out to the drain pipe 42 through the support portion 432 and discharged through the drain pipe 42.

Moreover, since the assembly step of the washing machine is also simplified, the difficulty of assembling the washing machine is reduced, and the work load of the installation personnel is reduced.

Further, the tank wall of the outer tank 1 is provided with at least one suspension ear 2 projecting outward in the radial direction. The suspension ear 2 is closely and fixedly connected to the wall surface. The outer tank 1 of the present invention is suspended on the wall surface via the suspension ear 2, and does not need to be supported by a member such as a damper. As a result, the number of members of the washing machine is reduced, so that the production cost and the difficulty of assembling the washing machine are further reduced. Moreover, since the size and weight of the entire washing machine are reduced, the appearance of the washing machine is optimized and the reliability of the wall hanging of the washing machine is improved. Preferably, one suspension ear 2 is provided at each of the four corners of the tank wall of the outer tank 1. More preferably, the suspension ears 2 are provided on two height surfaces.

A wall-mounted washing machine is a washing machine that is used by hanging it on the wall. The wall-mounted washing machine of the present invention includes an outer tub 1 that is directly assembled to the wall surface, and does not need to be supported by a member such as a damper. As a result, the number of members of the washing machine is reduced, so that the production cost and the difficulty of assembling the washing machine are further reduced. Moreover, since the size and weight of the entire washing machine are reduced, the appearance of the washing machine is optimized.

When the drain pipe 4242 is installed at one end of the outer tank 11 that is not close to the wall, it is easily exposed to the outside and the appearance is deteriorated. Moreover, since the drain pipe 42 cannot be fixed in the process of connecting to the floor drain port, the drain pipe 42 is damaged as a result of wobbling and vibration. Therefore, in the present application, the other end of the drainage pipe 42 penetrates the housing below the one end near the wall in the outer tub 1 and extends to the outside of the washing machine.

This structure is simple, does not occupy a large amount of space, and is easy to install and repair.

Further, the support portion 432 extends from the drain valve assembly 41 while inclining toward one end near the wall in the outer tank 1. As a result, the communication point between the drain pipe 42 and the support portion 432 is lower than the communication point between the support portion 432 and the drain valve assembly 41.

In the above plan, the support portion 432 extends from the drain valve assembly 41 while inclining toward one end near the wall in the outer tank 1. As a result, the water in the support portion 432 flows out from the drain pipe 42 without completely remaining, and does not flow back. Further, the communication point between the drain pipe 42 and the support portion 432 is lower than the communication point between the support portion 432 and the drain valve assembly 41, so that the water in the support portion 432 is discharged better and the water is discharged. This is to prevent residual or backflow.

Further, the washing machine includes an overflow pipe 51 for discharging bubbles and water overflowing from the inside of the outer tub 1 to the outside of the washing machine. The overflow pipe 51 communicates with the drain pipe 42 through the support portion 432.

Preferably, the overflow pipe 51 communicates with the drain pipe 42 through the support portion 432 at one end of the outer tank 1 near the wall.

In the above plan, the washing machine further includes a ventilation device 5 installed at the rear of the outer tub 1 to realize the flow of air between the inside of the outer tub 1 and the outside of the outer tub 1.

The other end of the overflow pipe 51 communicates with the drain pipe 42 through the support portion 432. Specifically, the other end of the overflow pipe 51 communicates with the drain pipe 42 through the support portion 432 at one end near the wall of the outer tank 1.

As shown in FIGS. 1 to 12, in this embodiment, the drain valve assembly 41 is disclosed. The drain valve assembly 41 is for sealing a motor for supplying power to the drain valve assembly 41, a mounting housing 411 including a cavity for accommodating the motor, and a cavity of the mounting housing 411 installed in the mounting housing 411. Includes a sealed structure 412.

In the above plan, the drain valve assembly 41 is provided with a motor for supplying power for drainage (for example, drainage from a washing machine), and protection of the motor is particularly important. Therefore, by installing the mounting housing 411 to provide a cavity for accommodating the motor, it is possible to prevent the motor from being damaged by an impact or the like and to prevent the motor from vibrating excessively. The sealing structure 412 is used to seal the cavity of the mounting housing 411 and prevents the motor from being damaged by water or steam.

Further, the mounting housing 411 includes a first housing 4111 and a second housing 4112. The first housing 4111 and the second housing 4112 are removably connected. The sealed structure 412 is installed at the connection point between the first housing 4111 and the second housing 4112.

In the above plan, the mounting housing 411 includes a first housing 4111 and a second housing 4112 to which the mounting housing 411 is detachably connected in order to facilitate mounting and repair of the motor. However, since there is a gap between the two housings, water / steam may enter the cavity of the mounting housing 411 through the gap and damage the motor. Therefore, by installing the sealing structure 412 at the connection point between the first housing 4111 and the second housing 4112, the defect that water / water vapor enters between the two housings is solved.

Further, the sealing structure 412 includes a sealing portion 4121 installed at the connection portion of the first housing 4111 / the second housing 4112 and an engaging portion 4122 installed at the connection portion of the second housing 4112 / the first housing 4111. include. By engaging the sealing portion 4121 and the engaging portion 4122, the connection portion between the first housing 4111 and the second housing 4112 is sealed.

In the above plan, the sealing structure 412 includes a sealing portion 4121 and an engaging portion 4122. By engaging these, mounting and repair can be facilitated, and a good sealing effect can be obtained.

Further, the connection points of the first housing 4111 / second housing 4112 include connection end 5211 surfaces that engage and contact each other. The sealing portion 4121 is a protruding portion projecting from the connection end 5211 surface of the first housing 4111 / second housing 4112. The engaging portion 4122 is a concave groove portion installed on the connection end 5211 surface of the second housing 4112 / first housing 4111.

Further, the protruding portion extends into the concave groove portion to position and seal the connection end 5211 surface of the first housing 4111 and the second housing 4112.

In the above plan, the sealing portion 4121 is a protruding portion protruding from the connecting end 5211 surface, and the engaging portion 4122 is a concave groove portion installed on the connecting end 5211 surface. The protrusion extends into the groove to position and seal the connection end 5211 surface of the first housing 4111 and the second housing 4112. Therefore, the sealing effect is excellent, and the risk of water entering the inside of the mounting housing 411 is completely eliminated. When water vapor attempts to enter the interior of the mounting housing 411, it must first bypass the protrusions and grooves. In this process, the water vapor collides with the wall many times and condenses into water, so that it cannot enter the cavity of the mounting housing 411. That is, water and water vapor correspond to forming an N-type labyrinth seal, and the risk of water and water vapor entering the cavity of the mounting housing 411 is greatly reduced, so that the sealing effect is excellent. Further, since the protruding portion extends into the concave groove portion to perform the action of position restriction and mounting, the mounting of the first housing 4111 and the second housing 4112 becomes much easier.

Further, the protrusion has a continuous protrusion structure installed on the connection end 5211 surface of the first housing 4111 / the second housing 4112, and the concave groove portion has a continuous concave groove structure that engages with the protrusion. Is.

In the above plan, the protruding portion has a continuous protruding structure and seals the entire connection end 5211 surface, so that the sealing effect is excellent.

Further, the protruding portion has a rectangular cross section in the stretching direction, and the concave groove portion has the same shape and size as the protruding portion. Preferably, the sides and corners of the rectangle away from the connection end 5211 surface are rounded and chamfered.

In the above plan, the protruding portion has a rectangular cross section in the stretching direction, and the concave groove portion matches the shape and size of the protruding portion, so that the sealing effect is excellent. In a preferred embodiment, the sides and corners of the rectangle away from the connection end 5211 surface are rounded and chamfered so that the concave groove portion is not damaged during the mounting or dismounting process.

As shown in FIGS. 1 to 12, in this embodiment, the outer tub 1 is included, and air is further installed at the rear of the outer tub 1 between the inside of the outer tub 1 and the outside of the outer tub 1. A wall-mounted washing machine including a ventilation device 5 that realizes flow is disclosed. The ventilation device 5 has an exhaust hole formed on the rear wall of the outer tank 1 and communicating with the inside of the outer tank 1, one end of which is connected to the exhaust hole, and the other end of bubbles and water overflowing from the inside of the outer tank 1. The overflow pipe 51, one end of which communicates with the overflow pipe 51, the other end extends to a position higher than the exhaust hole, and the other end overflows to the relevant portion. It includes a ventilation pipe 52 provided with a defoaming structure 521 that breaks the foam into a liquid and guides it to the overflow pipe 51.

In the above plan, the wall-mounted washing machine is different from a normal drum washing machine in that it is installed on one flat surface. A wall-mounted washing machine is a washing machine that is used by hanging it on the wall. Since the wall-mounted washing machine described in the present invention includes a ventilation device 5 that realizes the flow of air between the inside and the outside of the outer tub 1, the risk of the outer tub 1 bursting due to the inability to ventilate is prevented. Further, since the ventilation device 5 is installed at the rear portion of the outer tub 1, the side space of the outer tub 1 is saved as compared with the case where the ventilation device 5 is installed at the side portion of the outer tub 1, and the volume of the wall-mounted washing machine is increased. It gets smaller. Moreover, since the ventilation device 5 can be installed between the rib structures of the rear wall of the outer tank 1, it does not occupy a large space on the rear wall of the outer tank 1. The ventilation device 5 includes an exhaust hole that communicates with the inside of the outer tank. Since the exhaust hole is installed on the rear wall of the outer tank 1, it is easy to connect the overflow pipe 51 to the rear wall of the outer tank 1. The ventilation device 5 further includes an overflow pipe 51 that discharges bubbles and water overflowing from the outer tub 1 to the outside of the washing machine. One end of the overflow pipe 51 communicates with an exhaust hole installed above the rear wall of the outer tank 1, and the other end communicates with the drainage device 4, so that the foam overflows from above the outer tank 1. The water is discharged to the outside of the washing machine through the drain device 4. The ventilation device 5 further includes a ventilation pipe 52 for flowing air between the inside and the outside of the outer tank 1. One end of the ventilation pipe 52 communicates with the overflow pipe 51, the other end communicates with the inside of the outer tank 1 through the overflow pipe 51, and the other end communicates with the outside of the outer tank 1. As a result, the flow of air is realized between the inside and the outside of the outer tank 1. Since the other end of the ventilation pipe 52 extends to a position higher than the exhaust hole, it is possible to prevent bubbles from directly overflowing from the ventilation pipe 52. Since the other end of the ventilation pipe 52 extends to a position higher than the exhaust hole, a larger pressure is required for the bubbles to overflow from the ventilation pipe, and the possibility of the bubbles overflowing is greatly reduced. The other end of the ventilation pipe 52 is further provided with a defoaming structure 521 that breaks the bubbles overflowing to the relevant portion into a liquid and guides the foam to the overflow pipe. The defoaming structure 521 prevents bubbles from overflowing from the washing machine through the ventilation pipe 52, and does not interfere with the ventilation function of the ventilation pipe 52.

Further, the exhaust hole is installed in the highest water level portion inside the outer tank 1. Preferably, the exhaust hole is installed on the diameter of the axis vertically penetrating the rear wall of the outer tank 1 and communicates with the maximum water level inside the outer tank 1.

In the above plan, since the exhaust hole is installed at the highest water level inside the outer tank 1, unexpected overflow of bubbles and water generated when the installation position of the exhaust hole is low, and clean cleaning caused by the unexpected overflow. Issues such as being unable to do so are avoided. In a preferred embodiment, the exhaust holes are installed on the diameter of the axis vertically penetrating the rear wall of the outer tank 1, making it easier to find and identify the highest water level. Therefore, compared to the exhaust holes installed at other positions, it is possible to realize the function of overflowing bubbles and water when the bubbles and water are excessive, as well as increasing the difficulty when the bubbles overflow. Is.

Further, the washing machine includes a drainage device 4. One end of the overflow pipe 51 is connected to the exhaust hole, and the other end extends downward along the circumferential direction of the rear wall of the outer tank 1 and is connected to the drainage device 4. Preferably, the overflow pipe 51 extends downward along the circumferential direction of the rear wall of the outer tank 1 toward the axis. More preferably, one end of the overflow pipe 51 extends downward by a certain distance in the vertical direction from the exhaust hole, and then extends downward along the circumferential direction toward the axis of the rear wall of the outer tank 1.

In the above plan, the washing machine further includes a drainage device 4 for draining the washing water in the outer tub 1 from the washing machine. One end of the overflow pipe 51 is connected to an exhaust hole to realize air flow between the inside of the outer tank and the outside of the outer tank. Further, the other end is connected to the drainage device 4, and bubbles and water overflowing from the exhaust hole are discharged to the outside of the washing machine through the drainage device 4. The other end of the overflow pipe 51 extends downward along the circumferential direction of the rear wall of the outer tank 1, so that the ribs and ribs do not excessively interfere with the rib arrangement on the rear wall of the outer tank 1. It is installed between. Therefore, it does not occupy space and does not impair the distribution of ribs. In a preferred embodiment, the overflow pipe 51 extends downward along the circumferential direction of the rear wall of the outer tank 1 toward the axis, so that the length of the overflow pipe 51 is shortened, and bubbles and water are more removed. It can be discharged quickly. This avoids the situation where bubbles accumulate and overflow. In addition, the closer to the axis, the greater the vibration received, so that the bubbles are more easily broken and flow out. In a more preferred embodiment, one end of the overflow pipe 51 extends downward by a certain distance in the vertical direction from the exhaust hole, and then extends downward along the axial direction of the rear wall of the outer tank. .. The overflow pipe 51 extending downward in the vertical direction can more easily flow bubbles and water toward the drainage device 4.

Further, one end of the ventilation pipe 52 communicates with the overflow pipe 51, and the other end extends upward along the rear wall of the outer tank 1 to a position higher than the exhaust hole. Preferably, the ventilation pipe 52 is close to the overflow pipe 51, and the other end of the ventilation pipe 52 extends upward along the circumferential direction of the rear wall of the outer tank 1. More preferably, the other end of the ventilation pipe 52 is extended along the circumferential direction of the rear wall of the outer tank 1 and then continuously extended upward along the vertical direction to a position higher than the exhaust hole.

In the above plan, the ventilation pipe 52 extends upward along the rear wall of the outer tank 1. As a result, the ventilation pipe 52 is installed on the rear wall of the outer tank 1, but since the rear wall of the outer tank 1 has a relatively large vibration, the vibration of the ventilation pipe 52 installed on the rear wall of the outer tank 1 also increases. It becomes relatively large, and the bubbles tend to break further and become liquid due to the action of vibration. Further, since the ventilation pipe 52 extends upward along the rear wall of the outer tub 1, the space on the side wall of the outer tub 1 is saved as compared with the case where it is installed on the side wall of the outer tub 1, and the space of the side wall of the outer tub 1 is saved. The volume becomes smaller. Further, when the ventilation pipe 52 is installed on the rear wall of the outer tank 1, the ventilation pipe 52 can be fitted between the ribs on the rear wall of the outer tank 1, so that space is saved. In addition, since the other end of the ventilation pipe 52 extends to a position higher than the exhaust hole, a larger pressure is required for the bubbles to overflow from the ventilation pipe 52, and there is a great risk that the bubbles will overflow. Decreases to. In a preferred embodiment, the ventilation pipe 52 is close to the overflow pipe 51, and the other end of the ventilation pipe 52 extends upward along the circumferential direction of the rear wall of the outer tank 1. As a result, since the ribs are installed between the ribs without excessively interfering with the rib arrangement on the rear wall of the outer tank 1, the space is not occupied and the distribution of the ribs is not impaired. Further, the ventilation pipe 52 is close to the overflow pipe 51. That is, it is close to the axis of the rear wall of the outer tank 1. Since the vibration becomes larger as it gets closer to the axis, the bubbles become more fragile due to the vibration in the ventilation pipe, and it becomes more difficult to overflow from the ventilation pipe 52. In a more preferred embodiment, the other end of the ventilation pipe 52 extends along the circumferential direction of the rear wall of the outer tank 1 and then continues upward along the vertical direction to a position higher than the exhaust hole. Since it is stretched in the circumferential direction, the bubbles disappear when the vibration becomes large. Further, by continuing to extend upward along the vertical direction, the resistance to the rise of bubbles increases, and the tip of the other end of the ventilation pipe 52 becomes easier to install higher than the exhaust hole.

Further, the ventilation pipe 52 is provided with a bent portion 522. The bent portion 522 is provided at one end on the side communicating with the overflow pipe 51. Preferably, one end of the ventilation pipe 52 on the side communicating with the overflow pipe 51 is provided below the horizontal line of the axis penetrating the rear wall of the outer tank 1.

In the above plan, a bent portion 522 having an effect of breaking the overflowing bubbles and preventing the overflow is provided at one end on the side communicating with the overflow pipe 51. By interposing the extension of the ventilation pipe 52 by the bent portion 522, sufficient space is provided for the ventilation pipe 52 to extend upward. This prevents the situation where the ventilation pipe 52 exceeds the range of the rear part of the outer tank 1 in the process of extending upward and the space for continuing the extension is insufficient. In addition, the bubbles are broken by the bent portion 522. The bubbles are partially destroyed due to the increased pressure at the bends in the pipeline. Moreover, since the bent portion 522 also increases the pressure with respect to the progress of the bubbles in the ventilation pipe 52, the bubbles become more difficult to flow in the ventilation pipe 52. That is, the bent portion 522 plays an intervening role, prevents overflow, and also plays a role of breaking bubbles. Further, since one end of the ventilation pipe 52 on the side communicating with the overflow pipe 51 is provided below the horizontal line of the axis penetrating the rear wall of the outer tank 1, it is difficult for bubbles to overflow into the overflow pipe 51. It gets higher. Since the resistance force received when the bubbles continue to move downward is smaller than the resistance force received when the bubbles continue to move upward from the ventilation pipe 52, the overflow of the bubbles can be effectively reduced.

Further, the bent portion 522 is a protruding portion that protrudes outward along the radial direction of the rear wall of the outer tank 1. Preferably, the protrusion has an arc shape. More preferably, at least a part of the protrusion is provided below the horizontal line of the axis penetrating the rear wall of the outer tank 1.

In the above plan, the bent portion 522 is a protruding portion that protrudes outward along the radial direction of the rear wall of the outer tank 1. The foam overflows upward from the overflow pipe 51 into the ventilation pipe 52, but the protrusions protruding outward in the radial direction extend the foam path and increase the complexity of the path, so that the foam is upward. Increases resistance when continuing to overflow toward. Further, the projecting portion protruding outward in the radial direction includes a first stretching portion extending outward in the radial direction and a second stretching portion extending inward in the radial direction. The action of the vibration that the bubble receives in the first stretched portion changes from the larger one to the smaller one, and the action of the vibration received in the second stretched portion changes from the smaller one to the larger one. In the process of rising from the first stretched portion to the second stretched portion, the bubbles are gradually broken by the action of changing vibrations. In addition, in the process of ascending from the first stretched portion to the second stretched portion, the bubbles fluctuate due to the action of vibration, the resistance to the ascent, and the change of the ascending path, and it is easier for the bubbles to collide with each other. Disappears in. In a preferred embodiment, the protrusion is arcuate. The arc-shaped protrusion forms a structure similar to a semicircle, and can serve as a bent portion. Further, if the bending is to this degree, molding is easy. Alternatively, if it is a hose, it can be easily bent. Therefore, the molding cost does not increase and the mounting is easy. In a more preferred embodiment, since at least a part of the protruding portion is provided below the horizontal line of the axis penetrating the rear wall of the outer tank 1, it becomes more difficult for bubbles to overflow into the overflow pipe 51. Since the resistance force received when the bubbles continue to move downward is smaller than the resistance force received when the bubbles continue to move upward from the ventilation pipe 52, the overflow of the bubbles can be effectively reduced.

Further, the defoaming structure 521 is detachably installed at the other end of the ventilation pipe 52.

In the above plan, since the defoaming structure 521 is detachably installed at the other end of the ventilation pipe 52, the defoaming structure 521 can be easily attached, repaired, and cleaned. As a result, the defoaming structure 521 is installed at the other end of the ventilation pipe 52, so that foreign matter such as cotton is clogged and the situation that the ventilation is hindered is avoided.

Further, the defoaming structure 521 includes a tubular body. The tubular body includes a connection end 5211 installed at one end of the tubular body. The tubular body is detachably installed at the other end of the ventilation pipe 52 via the connection end 5211. Preferably, screws are provided both outside the connection end 5211 and inside the other end of the ventilation pipe 52. The tubular body is connected to the inside of the other end of the ventilation pipe 52 by turning the screw.

A defoaming end 5212 is installed at the other end of the tubular body. The inner diameter of the pipe at the connection end 5211 is smaller than the inner diameter of the pipe at the defoaming end 5212.

In the above plan, the connection end 5211 is mainly used to detachably install the defoaming structure 521 at the other end of the ventilation pipe 52. The connection end 5211 can be connected to the other end of the ventilation pipe 52 by a method such as engagement or screw connection. In the case of the screw connection method, two screws are provided inside the connection end 5211 and outside the other end of the ventilation pipe 52, or by providing screws outside the connection end 5211 and inside the other end of the ventilation pipe 52. There is a screw connection method. In a preferred embodiment, a screw is provided both on the outside of the connection end 5211 and inside the other end of the ventilation pipe 52, and the tubular body can turn the screw to the inside of the other end of the ventilation pipe 52. Connected to. Since the connection end 5211 is installed inside the other end of the ventilation pipe 52, the inner diameter is small, which also has a certain effect of preventing the overflow of bubbles. The fact that the inner diameter of the pipe of the connection end 5211 is smaller than the inner diameter of the pipe of the defoaming end 5212 corresponds to the appearance of a constricted portion of the connection end 5211 in the ventilation pipe 52. When the foam reaches the constriction portion of the connection end 5211, it is subjected to the pressure due to the constriction. As a result, a part of the foam is broken by the action of pressure, and no further progress is made to the defoaming end 5212. Further, the remaining portion of the foam continues to proceed to the defoaming end 5212, and is blocked by the defoaming end 5212 and destroyed.

Further, the inside of the defoaming end includes at least one defoaming plate 5213. The defoaming plate 5213 extends inside the defoaming end 5212 along the radial direction and the axial direction, respectively. A gap for ventilation is provided between the defoaming plate 5213 and the inner wall of the tubular body and / or between the defoaming plate 5213. Preferably, the defoaming plate 5213 extends from the boundary portion between the connecting end 5211 and the defoaming end 5212 toward the end of the defoaming end 5212. More preferably, the defoaming plate 5213 is integrally molded inside the defoaming end 5212.

In the above plan, the inside of the defoaming end includes a defoaming plate 5213 that prevents the overflow of bubbles. The defoaming plate 5213 is installed at the center of the defoaming end 5212 in the radial direction and extends along the axial direction. In a preferred embodiment, the defoaming plate 5213 extends along the axial direction to the interface between the defoaming end 5212 and the connecting end 5211. When the foam overflows from the connection end 5211 toward the defoaming end 5212, it is first pressed by the constricted portion of the connecting end 5211 to break a part, and the remaining part is pressed again by the defoaming plate 5213. It will be destroyed by that. Therefore, bubbles do not overflow from the defoaming end 5212. Further, since the gap between the defoaming plate 5213 and the inner wall is a gap for ventilation, the defoaming structure 521 can prevent the overflow of bubbles on the premise that the ventilation function of the ventilation pipe 52 is realized. Is. The overflow barrier includes at least two defoaming plates 5213. The defoaming plates 5213 are installed parallel to each other or cross each other. There is a gap for ventilation between the defoaming plate 5213 and between the defoaming plate 5213 and the inner wall of the defoaming end 5212. When the foam overflows from the connection end 5211 toward the defoaming end 5212, it is first pressed by the constricted portion of the connecting end 5211 to break a part, and the remaining part is pressed again by the defoaming plate 5213. It will be destroyed by that. Therefore, bubbles do not overflow from the defoaming end 5212. The integrally molded defoaming plate 5213 eliminates processing and mounting procedures, saves costs, and is easy to use.
