DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments are clearly and completely described below. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0052] Embodiment 1

[0053] like Figure 1-12 As shown, this embodiment discloses a wall-mounted washing machine, including an outer drum 1, a drainage device 4 for discharging water inside the outer drum 1 to the outside of the washing machine, and an overflow pipe 51 for discharging foam and water overflowing from the outer drum 1 to the outside of the washing machine, wherein the drainage device 4 includes:

[0054] The drain valve assembly 41 is connected to the outer tube 1 and forced to drain the water in the outer tube 1;

[0055] A drain pipe 42 is connected to the drain valve assembly 41 to drain the water discharged from the drain valve assembly 41 out of the washing machine;

[0056] The mounting structure 43 is used to fix and support the drain pipe 42 and the overflow pipe 51 on one end of the outer tube 1 close to the wall.

[0057] In the above scheme, the wall-mounted washing machine is different from the ordinary drum washing machine which is placed on a plane. The wall-mounted washing machine is a washing machine that is hung on the wall for use. The wall-mounted washing machine of the present invention includes a drainage device 4, and the drainage device 4 includes a drainage valve assembly 41 that forces the water in the outer drum 1 to be discharged from the outer drum 1 to the outside during the corresponding washing stage, and the water forced to be discharged from the outer drum 1 is discharged to the outside of the washing machine through a drainage pipe 42. The drainage pipe 42 generally has a hose that finally discharges the water to the outside of the washing machine, which is prone to vibration, collision, etc. and causes damage. The wall-mounted washing machine generally also includes a ventilation device 5 to achieve air circulation between the inside and outside of the outer drum 1 to prevent the outer drum 1 from exploding due to the inability to ventilate the outer drum 1. The ventilation device 5 includes an overflow pipe 51, which can discharge the foam and water overflowing from the inner part of the outer drum 1 to the outside of the washing machine, and can also achieve ventilation inside the outer drum 1. The drainage hose of an ordinary wall-mounted washing machine extends to the outside of the washing machine after passing through the rear panel, and plays a fixing role by passing through the rear panel. However, due to the sharp edges or rib structures that may exist on the edges of the holes on the rear panel, the hose is damaged when the hose vibrates, resulting in a high damage rate of the hose. Moreover, when the overflow pipe 51 is directly connected to the drain pipe 42, since the drain pipe 42 is a hose, it is easy to leak or shake and detach. In order to solve this problem, the drainage device 4 of the wall-mounted washing machine described in the present invention also includes a mounting structure 43, which is used to install and fix the drain pipe 42 and the overflow pipe 51, and the drain pipe 42 and the overflow pipe 51 are fixedly supported at one end of the outer drum 1 close to the wall, and the water is led to the rear side of the outer drum 1 and discharged smoothly, so as to prevent the drain pipe 42 from being exposed and unsightly due to the setting of the drain pipe 42 at the front end of the outer drum 1, and the damage to the drain hose caused by shaking and vibration due to the inability to fix the drain hose during the connection process with the floor drain; in addition, the mounting structure 43 is provided to prevent the drain pipe 42 and the overflow pipe 51 from shaking and vibrating during drainage.

[0058] Furthermore, a base is provided at one end of the outer drum 1 of the washing machine close to the wall, and the drain pipe 42 and the overflow pipe 51 are fixedly supported on the base through a mounting structure 43 .

[0059] Furthermore, at least one hanging ear 2 protruding radially outward is provided on the wall of the outer cylinder 1, and the hanging ear 2 is attached to and fixedly connected to the wall surface, and the drain pipe 42 and the overflow pipe 51 are fixedly supported on the hanging ear 2 through the mounting structure 43.

[0060] Preferably, a hanging ear 2 is respectively provided at the four corners of the wall of the outer cylinder 1, and the drain pipe 42 and the overflow pipe 51 are fixedly supported on a hanging ear 2 at the lower side of the outer cylinder 1 through a mounting structure 43.

[0061] More preferably, the drain pipe 42 and the overflow pipe 51 are fixedly supported on a hanging ear 2 on the lower side of the outer tube 1 close to the drain valve assembly 41 through a mounting structure 43 .

[0062] In the above scheme, a base is provided, which does not occupy the space at one end of the outer drum 1 close to the wall, and provides a convenient installation medium for the mounting structure 43 to be fixedly supported at the end of the outer drum 1 close to the wall. Because the cost and operation difficulty of direct installation on the wall are very high, a base is provided. One embodiment of the base can be at least one radially outwardly protruding ear 2 provided on the wall of the outer drum 1, or the base and the ear 2 can be two different schemes. The outer drum 1 of the present invention is hung on the wall through the ear 2, and does not need to be supported by components such as dampers, thereby reducing the number of components on the washing machine, thereby further reducing the production cost and assembly difficulty of the washing machine, while also reducing the overall size and weight of the washing machine, optimizing the appearance of the washing machine, and improving the reliability of the wall-mounted washing machine. The drain pipe 42 and the overflow pipe 51 are fixedly supported on the hanging ear 2 through the mounting structure 43. The drain pipe 42 and the overflow pipe 51 are arranged on the rear side of the outer tube 1 and fixed on the hanging ear 2, which prevents the occurrence of the problem that the drain pipe 42 cannot be fixed due to the lack of a rear panel in the present invention, thereby avoiding the shaking, vibration, damage, water splashing and other problems caused by the inability to fix the drain pipe 42. In order to facilitate the installation, maintenance, inspection, replacement and other operations of the drain pipe 42, the drain pipe 42 is detachably arranged on the hanging ear 2 through the mounting structure 43. A hanging ear 2 is respectively provided at the four corners of the wall of the outer tube 1. In the preferred embodiment, the hanging ear 2 is arranged on two height planes. Further, a support member 3 extending toward the outer tube 1 is provided on the wall, and the support member 3 passes through the hanging ear 2 and is supported by contacting the hanging ear 2. The specific assembly steps of the outer cylinder 1 of the present invention are: first install the support member 3 on the wall, then hang the lug 2 on the support member 3 to achieve the preliminary fixation of the outer cylinder 1, and finally screw the nut onto the support member 3 passing through the lug 2, so that the lug 2 is clamped and fixed on the support member 3 between the wall and the nut, thereby achieving the assembly of the outer cylinder 1. In a preferred embodiment, a shock-absorbing gasket is clamped and fixed between the wall and the lug 2, and between the lug 2 and the nut, respectively, to reduce the noise generated by the washing machine during operation. Alternatively, the lug 2 is fixedly connected to the wall via a bolt, so that the lug 2 is clamped and fixed on the screw between the bolt nut and the wall. In a preferred embodiment, a shock-absorbing gasket is clamped and fixed between the wall and the lug 2, and between the lug 2 and the bolt nut, to reduce the noise generated by the washing machine during operation. The drain pipe 42 and the overflow pipe 51 of the present invention are arranged on a hanging ear 2 on the lower side of the outer tube 1 through the mounting structure 43, and are arranged both on the rear side of the outer tube 1 and on the lower side of the outer tube 1. Water can be discharged more conveniently without residue under the action of gravity, and the appearance is ensured, and the drain pipe 42 and the overflow pipe 51 are fixedly arranged. In a preferred embodiment, the drain pipe 42 and the overflow pipe 51 are arranged on a hanging ear 2 on the lower side of the outer tube 1 near the drain valve assembly 41 through the mounting structure 43, which simplifies the device, and simplifies the method and structure of setting the drain pipe 42 by the mounting structure 43.

[0063] Furthermore, the rear wall of the outer cylinder 1 is provided with an exhaust hole 53 connected to the interior of the outer cylinder 1. The overflow pipe 51 is arranged at the rear of the outer cylinder 1, one end of which is connected to the interior of the outer cylinder 1 through the exhaust hole 53, and the other end of which is connected to the drainage device 4.

[0064] Preferably, one end of the overflow pipe 51 is connected to the highest water level inside the outer tube 1 through the exhaust hole 53, and the other end is fixedly supported on one end of the outer tube 1 close to the wall through the mounting structure 43.

[0065] In the above scheme, the overflow pipe 51 is arranged at the rear of the outer drum 1, which saves the side space of the outer drum 1 compared with being arranged at the side of the outer drum 1, reduces the volume of the wall-mounted washing machine, and the overflow pipe 51 can be arranged between the rib structures of the rear wall of the outer drum 1, and does not occupy much space on the rear wall of the outer drum 1. The rear wall of the outer drum 1 includes an exhaust hole 53 connected to the inside of the outer drum 1, and the exhaust hole 53 is arranged on the rear wall of the outer drum 1, which facilitates the connection of the overflow pipe 51 to the rear wall of the outer drum 1. One end of the overflow pipe 51 is connected to the exhaust hole 53 arranged above the rear wall of the outer drum 1, and the other end is connected to the drainage device 4, so that the foam and water overflowing from the top of the outer drum 1 are discharged out of the washing machine through the drainage device 4. In a preferred embodiment, the overflow pipe 51 is connected to the highest water level inside the outer drum 1 through the exhaust hole 53, so as to avoid the accidental overflow of foam and water caused by the exhaust hole 53 being arranged at a lower position, thereby causing problems such as unclean washing. The other end of the overflow pipe 51 is fixedly supported on the end of the outer tube 1 close to the wall by the mounting structure 43, so as to prevent the overflow pipe 51 from extending from the bottom of the outer tube 1 toward the drain valve assembly 41 to the front end of the outer tube 1 and then discharging water through the drain pipe 42, which may cause drainage obstruction, or to prevent the overflow pipe 51 from being directly connected to the drain pipe 42 due to the loose connection caused by the vibration of the drain pipe 42 and the overflow pipe 51 respectively, thereby causing overflow.

[0066] Furthermore, the mounting structure 43 includes:

[0067] The support portion 432 is used to support the drain pipe 42 and the overflow pipe 51 at one end of the outer tube 1 close to the wall;

[0068] The mounting portion 431 is used to mount and fix the drain pipe 42 and the overflow pipe 51 on one end of the outer tube 1 close to the wall;

[0069] Preferably, the mounting portion 431 and the supporting portion 432 are integrally formed.

[0070] In the above scheme, the support part 432 supports the drain pipe 42 and the overflow pipe 51 at one end of the outer drum 1 close to the wall, that is, supports one end of the drain pipe 42 and the end of the overflow pipe 51 for drainage at one end of the outer drum 1 close to the wall, and supports the drain valve assembly 41 while supporting the drain pipe 42 and the overflow pipe 51 to make the installation more secure, so as to prevent the drain pipe 42 and the overflow pipe 51 from shaking, loosening, damage and other dangers under the action of vibration. The drain valve assembly 41 is generally not arranged at the rear side of the outer drum 1 due to the limitations of factors such as shape and drainage position. When the drain pipe 42 is directly led out from the drainage port of the drain valve assembly 41, the position of the drain pipe 42 will be forward, which is easy to shake and not beautiful, and the drain pipe 42 led out of the washing machine cannot be fixed. Therefore, the support part 432 is provided to support the drain pipe 42 and the overflow pipe 51 at one end of the outer drum 1 close to the wall. The mounting portion 431 mounts the drain pipe 42 and the overflow pipe 51 on the end of the outer tube 1 close to the wall, further achieving the purpose of fixing the drain pipe 42 and the overflow pipe 51 to prevent danger caused by vibration. In one embodiment, the mounting portion 431 and the drain pipe 42 and the overflow pipe 51 are integrally formed, which saves costs and is convenient for processing and molding, but increases the difficulty during installation; in another embodiment, the mounting portion 431 and the drain pipe 42 and the overflow pipe 51 are detachably connected, and installation and disassembly are simple and convenient. In a preferred embodiment, the mounting portion 431 is integrally formed with the support portion 432, and the drain pipe 42 and the overflow pipe 51 are supported by the support portion 432 and fixed to the end of the outer tube 1 close to the wall through the mounting portion 431, which has a simple structure, is convenient for molding, and is easy to install and maintain, saving costs.

[0071] Furthermore, one end of the support portion 432 is connected to the drain valve assembly 41 , and the other end is connected to both the drain pipe 42 and the overflow pipe 51 .

[0072] In the above scheme, one end of the support portion 432 is connected to the drain valve assembly 41 to receive the water discharged by the drain valve assembly 41, and the other end is connected to one end of the drain pipe 42 to discharge the water discharged by the drain valve assembly 41 out of the washing machine through the drain pipe 42. The other end of the support portion 432 is also connected to the other end of the overflow pipe 51, and the other end of the overflow pipe 51 is connected to the drain pipe 42 through the support portion 432 to discharge the foam and water overflowing from the outer drum 1 out of the washing machine through the drain pipe 42.

[0073] Further, the support portion 432 is a tubular structure, one end of which is connected to the drain valve assembly 41, and the other end of which extends to the end of the outer tube 1 close to the wall, and is connected to the drain pipe 42 and the overflow pipe 51, and supports the drain pipe 42 and the overflow pipe 51 at the end of the outer tube 1 close to the wall.

[0074] Preferably, the support portion 432 is a hard pipe, and is arranged on the same horizontal plane as the drain valve assembly 41.

[0075] More preferably, the support portion 432 extends from the drain valve assembly 41 toward an end of the outer tube 1 close to the wall and is gradually inclined downward, and a connection point between the drain pipe 42 and the support portion 432 is lower than a connection point between the support portion 432 and the drain valve assembly 41 .

[0076] In the above scheme, the support part 432 is a tubular structure, which has a hollow cavity for water to flow through. The drain valve assembly 41 and the drain pipe 42 and the overflow pipe 51 are connected through the tubular structure and are respectively arranged at both ends of the tubular structure, which not only guides the water of the drain valve assembly 41 to the drain pipe 42, but also supports the drain valve assembly 41, and supports the drain pipe 42 and the overflow pipe 51 at one end of the outer tube 1 close to the wall to facilitate the extension and fixation of the other end of the drain pipe 42. In addition, the overflow pipe 51 is connected to the drain pipe 42 through the support part 432 to drain the overflow water and foam out of the washing machine. In a preferred embodiment, the support part 432 is a hard pipe to achieve the function of supporting the drain pipe 42, the overflow pipe 51 and the drain valve assembly 41, and the soft pipe cannot achieve the supporting function. The support part 432 and the drain valve assembly 41 are arranged on the same horizontal plane, with a simple structure, not occupying much space, and convenient for installation and maintenance. In a more preferred embodiment, the support portion 432 extends from the drain valve assembly 41 to the end of the outer tube 1 close to the wall, so that the water in the support portion 432 flows out of the drain pipe 42 completely, without residue and without backflow, and the foam and water discharged from the overflow pipe 51 to the support portion 432 will not flow back. The connection point between the drain pipe 42 and the support portion 432 is lower than the connection point between the support portion 432 and the drain valve assembly 41, so as to better drain the water in the support portion 432 and prevent water residue or backflow.

[0077] Furthermore, the mounting portion 431 includes a mounting plate for detachably mounting the support portion 432 on one end of the outer tube 1 close to the wall, and the mounting plate is provided with a mounting through hole 4311, and a screw passes through the mounting through hole 4311 to detachably mount the mounting plate on one end of the outer tube 1 close to the wall.

[0078] Preferably, the corners of the mounting plate are smoothly rounded.

[0079] In the above solution, the mounting plate detachably sets the drain pipe 42 and the overflow pipe 51 on the hanging ear 2 / base, one end face of the mounting plate contacts the support portion 432 and is integrally formed with the support portion 432, and the other end face opposite to the end face contacts the hanging ear 2 or the base, and is detachably connected to the hanging ear 2 or the base by screws. In a preferred embodiment, the corners of the mounting plate are rounded to prevent sharp corners from scratching the hanging corners or other positions or the installation / removal personnel during the installation / removal process.

[0080] Furthermore, the mounting portion 431 further includes a limiting portion 4312 connected to the limiting mounting plate.

[0081] Preferably, the limiting portion 4312 is integrally formed on the side of the mounting plate.

[0082] More preferably, the limiting portion 4312 includes a protrusion that continues to extend from the side of the mounting plate.

[0083] In the above scheme, the limiting portion 4312 limits the connection of the mounting plate to the hanging ear 2 or the base to prevent mis-installation and movement after installation. In a preferred embodiment, the limiting portion 4312 is integrally formed on the side of the mounting plate, saving space, requiring no additional settings, requiring no connection, and saving costs. In a more preferred embodiment, the limiting portion 4312 includes a protrusion that continues to extend from the side of the mounting plate, requiring no additional components, saving costs, and the setting of the protrusion achieves the function of limiting only in shape. The protrusion may be a plate-like structure in the shape of a rectangle, trapezoid, or other polygon.

[0084] Furthermore, one end of the overflow pipe 51 is connected to the exhaust hole 53, and the other end extends downward along the circumference of the rear wall of the outer tube 1 and is connected to the support portion 432, and is connected to the drain pipe 42 through the support portion 432.

[0085] Preferably, the other end of the overflow pipe 51 extends downward along the circumference of the rear wall of the outer cylinder 1 and then extends obliquely toward the front of the outer cylinder 1 to the same horizontal plane as the support portion 432 , and then extends horizontally to the support portion 432 and is connected to the support portion 432 .

[0086] In the above scheme, the overflow pipe 51 extends downward along the circumference of the rear wall of the outer cylinder 1 to avoid excessive disturbance of the layout of the ribs on the rear wall of the outer cylinder 1. It is arranged between the ribs and does not occupy space and does not interrupt the distribution of the ribs. In a preferred embodiment, the overflow pipe 51 extends downward along the circumference close to the axis of the rear wall of the outer cylinder 1 to reduce the length of the overflow pipe 51. Foam and water can be discharged faster to avoid foam overflow caused by foam accumulation. At the same time, the closer to the axis, the greater the vibration, and the easier it is for the foam to break and flow out. In a more preferred embodiment, one end of the overflow pipe 51 extends downward from the exhaust hole 53 in the vertical direction for a distance, and then extends downward along the axial direction close to the axis of the rear wall of the outer cylinder 1. The overflow pipe 51 extending downward in the vertical direction makes it easier for foam and water to flow to the drainage device 4. The other end of the overflow pipe 51 extends downward along the circumference of the rear wall of the outer cylinder 1 and then extends obliquely toward the front of the outer cylinder 1 to the same horizontal plane as the support portion 432, and then extends horizontally to the support portion 432 and is connected to the support portion 432 to facilitate the connection between the overflow pipe 51 and the support portion 432 without occupying excess space. The overflow pipe 51 is always behind the outer cylinder 1 and has no room for vibration. It will not cause much vibration when it extends from the rear of the outer cylinder 1 and then extends obliquely to the connection, and water with foam is not likely to be liquid-sealed at the connection, causing the foam to rise.

[0087] Embodiment 2

[0088] like Figure 1-12 As shown, this embodiment discloses a wall-mounted washing machine, including an outer drum 1, and also includes a drainage device 4, wherein the drainage device 4 includes: a drainage valve assembly 41, which is connected to the outer drum 1 and forcibly drains the water in the outer drum 1; a drainage pipe 42, which is connected to the drainage valve assembly 41 and drains the water discharged from the drainage valve assembly 41 out of the washing machine;

[0089] The mounting structure 43 is used to mount the drain pipe 42 on one end of the outer tube 1 close to the wall.

[0090] In the above scheme, the wall-mounted washing machine is different from the ordinary drum washing machine which is placed on a plane. The wall-mounted washing machine is a washing machine that is hung on the wall for use. The wall-mounted washing machine of the present invention includes a drainage device 4, and the drainage device 4 includes a drainage valve assembly 41 that forces the water in the outer drum 1 to be discharged from the outer drum 1 to the outside during the corresponding washing stage, and the water forced to be discharged from the outer drum 1 is discharged to the outside of the washing machine through a drainage pipe 42. The drainage pipe 42 generally discharges the water to the outside of the washing machine through a hose, which is prone to vibration, collision, etc. and causes damage. The drainage hose of an ordinary wall-mounted washing machine extends to the outside of the washing machine after passing through the rear panel. It plays a fixing role by passing through the rear panel. However, due to the sharp edges or rib structures that may exist on the edges of the holes on the rear panel, when the hose vibrates, it will cause damage to the hose, resulting in a high damage rate of the hose. In order to solve this problem, the drainage device 4 of the wall-mounted washing machine described in the present invention also includes a mounting structure 43 for mounting and fixing a drainage pipe 42. The drainage pipe 42 is arranged at one end of the outer drum 1 close to the wall, and water is led to the rear side of the outer drum 1 and discharged smoothly, thereby preventing the drainage pipe 42 from being exposed and unsightly due to being arranged at the front end of the outer drum 1, and preventing the drainage hose from being damaged by shaking or vibration caused by the inability to fix the drainage hose during the connection with the floor drain. In addition, the mounting structure 43 is arranged to prevent the drainage pipe 42 from shaking or vibrating during drainage and causing damage.

[0091] Furthermore, at least one hanging ear 2 protruding radially outward is provided on the wall of the outer cylinder 1 , the hanging ear 2 is attached to and fixedly connected to the wall surface, and the drain pipe 42 is arranged on the hanging ear 2 through a mounting structure 43 .

[0092] In the above scheme, the outer drum 1 of the present invention is hung on the wall through the hanging ear 2, and does not need to be supported by components such as dampers, thereby reducing the number of components on the washing machine, thereby further reducing the production cost and assembly difficulty of the washing machine, while also reducing the overall size and weight of the washing machine, optimizing the appearance of the washing machine, and improving the reliability of the wall-mounted washing machine. The drain pipe 42 is arranged on the hanging ear 2 through the mounting structure 43, which not only sets the drain pipe 42 on the rear side of the outer drum 1, but also fixes it on the hanging ear 2, thereby preventing the occurrence of the problem that the drain pipe 42 cannot be fixed due to the lack of a rear panel in the present invention, thereby avoiding the problems of shaking, vibration, damage, water splashing, etc. caused by the inability to fix the drain pipe 42. In order to facilitate the installation, maintenance, inspection, replacement and other operations of the drain pipe 42, the drain pipe 42 is detachably arranged on the hanging ear 2 through the mounting structure 43.

[0093] Furthermore, a hanging ear 2 is respectively provided at the four corners of the wall of the outer cylinder 1, and the drain pipe 42 is arranged on a hanging ear 2 on the lower side of the outer cylinder 1 through a mounting structure 43. Preferably, the drain pipe 42 is arranged on a hanging ear 2 on the lower side of the outer cylinder 1 close to the drain valve assembly 41 through a mounting structure 43.

[0094] In the above scheme, a lug 2 is respectively provided at the four corners of the wall of the outer cylinder 1. In a preferred embodiment, the lug 2 is provided on two height planes. Further, a support member 3 extending toward the outer cylinder 1 is provided on the wall, and the support member 3 passes through the lug 2 and is supported by the lug 2. The specific assembly steps of the outer cylinder 1 of the present invention are: firstly install the support member 3 on the wall, then hang the lug 2 on the support member 3 to achieve the preliminary fixation of the outer cylinder 1, and finally screw the nut onto the support member 3 passing through the lug 2, so that the lug 2 is clamped and fixed on the support member 3 between the wall and the nut, thereby achieving the assembly of the outer cylinder 1. In a preferred embodiment, a shock-absorbing gasket is clamped and fixed between the wall and the lug 2, and between the lug 2 and the nut, so as to reduce the noise generated by the washing machine during operation. Alternatively, the lug 2 is fixedly connected to the wall by a bolt, so that the lug 2 is clamped and fixed on the screw between the bolt nut and the wall. In a preferred embodiment, a shock-absorbing gasket is clamped and fixed between the wall and the hanging ear 2, and between the hanging ear 2 and the bolt nut to reduce the noise generated by the washing machine during operation. The drain pipe 42 of the present invention is arranged on a hanging ear 2 on the lower side of the outer cylinder 1 through a mounting structure 43, which is arranged both at the rear side of the outer cylinder 1 and at the lower side of the outer cylinder 1. Water can be discharged more conveniently without residue under the action of gravity, and the appearance is ensured, and the drain pipe 42 is fixedly arranged. In a preferred embodiment, the drain pipe 42 is arranged on a hanging ear 2 on the lower side of the outer cylinder 1 near the drain valve assembly 41 through a mounting structure 43, which simplifies the device, and simplifies the method and structure of setting the drain pipe 42 by the mounting structure 43.

[0095] Furthermore, the mounting structure 43 includes a mounting portion 431 for mounting the drain pipe 42 on one end of the outer tube 1 close to the wall. Preferably, the mounting portion 431 is detachably connected to or integrally formed with the drain pipe 42. More preferably, the drain pipe 42 is detachably arranged on one end of the outer tube 1 close to the wall through the mounting portion 431.

[0096] In the above scheme, the mounting structure 43 includes a mounting portion 431, and the mounting portion 431 mounts the drain pipe 42 on one end of the outer tube 1 close to the wall. In one embodiment, the mounting portion 431 and the drain pipe 42 are integrally formed, which saves cost and is convenient for processing and forming, but increases the difficulty during installation; in another embodiment, the mounting portion 431 and the drain pipe 42 are detachably connected, and the installation and disassembly are simple and convenient. In one embodiment, the mounting portion 431 is integrally formed on the hanging ear 2, and the drain pipe 42 is detachably set on the hanging ear 2. In a more preferred embodiment, the mounting portion 431 is detachably set on the hanging ear 2, which is more convenient for the installation, maintenance, inspection and replacement of the drain pipe 42.

[0097] Furthermore, the mounting portion 431 is a mounting plate for detachably mounting the drain pipe 42 on one end of the outer tube close to the wall, and a mounting through hole 4311 is provided on the mounting plate. A screw passes through the mounting through hole 4311 to detachably connect the mounting portion 431 to the hanging ear 2. Preferably, the corners of the mounting plate are smoothly transitioned.

[0098] In the above solution, the mounting structure 43 sets the drain pipe 42 on the hanging ear 2 through the mounting plate, one end face of the mounting plate contacts the drain pipe 42 and is detachably connected to the drain pipe 42 or is integrally formed with the drain pipe 42, and the other end face opposite to the end face contacts the hanging ear 2 and is detachably connected to the hanging ear 2 through screws. In a preferred embodiment, the corners of the mounting plate are rounded to prevent sharp corners from scratching the hanging corners or other positions or the installer / remover during the installation / removal process.

[0099] Furthermore, the hanging ear 2 is provided with a matching portion 21 that cooperates with the mounting plate. Preferably, the matching portion 21 is a groove on the hanging ear that is recessed toward the wall. More preferably, at least a portion of the shape of the matching portion 21 matches the shape of the mounting plate.

[0100] In the above scheme, the hanging ear 2 is provided with a matching portion 21 that matches with the mounting plate. The matching portion 21 provides great convenience for the installation of the mounting plate, which is equivalent to providing a limit for the installation of the mounting plate, preventing problems such as incomplete drainage or drainage backflow caused by other pipeline misconnections caused by the incorrect installation of the mounting plate. The matching portion 21 can be a protrusion set on the mounting surface of the hanging ear 2 to prevent installation misalignment and facilitate the installation of the mounting plate. Because the protrusion may affect other components and may occupy space, in a preferred embodiment, the matching portion 21 is a groove that is recessed toward the wall, which not only facilitates the installation of the mounting plate, prevents incorrect installation, but also saves space. In a more preferred embodiment, at least part of the shape of the matching portion 21 matches the shape of the mounting plate to prevent the mounting plate from shaking after installation.

[0101] Furthermore, the mounting structure 43 also includes a limiting portion 4312 for limiting the connection of the drain pipe 42 to the hanging ear 2. Preferably, the limiting portion 4312 is arranged on the mounting plate, and more preferably, the limiting portion 4312 is integrally formed on the mounting plate.

[0102] In the above solution, the limiting portion 4312 limits the connection between the mounting structure 43 and the hanging ear 2 to prevent mis-installation and movement after installation. In a preferred embodiment, the limiting portion 4312 is arranged on the mounting plate to save space. In a more preferred embodiment, the limiting portion 4312 is integrally formed on the mounting plate, and no additional arrangement or connection is required, which saves costs.

[0103] Furthermore, the limiting portion 4312 is arranged on the side of the mounting plate and matches the shape of the matching portion 21 on the hook 2. Preferably, the limiting portion 4312 includes a protruding portion that continues to extend from the side of the mounting plate, and the shape of the protruding portion matches the matching portion 21 of the hook 2. More preferably, the protruding portion is a rectangular, trapezoidal or polygonal plate-like structure.

[0104] In the above solution, the limiting portion 4312 is arranged on the side of the mounting plate, and matches the shape of the matching portion 21 on the hanging ear 2 to further limit the mounting plate. In a preferred embodiment, the limiting portion 4312 includes a protruding portion that continues to extend from the side of the mounting plate, and the shape of the protruding portion matches the matching portion 21 of the hanging ear 2, and no additional components are required, which saves costs. The shape of the protruding portion matches the matching portion 21 of the hanging ear 2 to better limit the installation of the mounting plate, and the setting of the protruding portion only achieves the limiting effect in shape. The protruding portion can be a plate-like structure in the shape of a rectangle, a trapezoid, or other polygons.

[0105] Furthermore, the mounting structure 43 also includes a support portion 432, one end of the support portion 432 is connected to the drain valve assembly 41, and the other end is connected to the drain pipe 42. The support portion 432 and the mounting portion 431 fix and support the drain pipe 42 at one end of the outer tube 1 close to the wall.

[0106] In the above solution, the mounting structure 43 includes a mounting portion 431 for fixing the drain pipe 42 to the end of the outer tub 1 close to the wall and a supporting portion 432 for supporting the drain pipe 42 to the end of the outer tub 1 close to the wall. The drain pipe 42 is fixedly supported by the mounting structure 43 to the end of the outer tub 1 close to the wall. One end of the supporting portion 432 is connected to the drain valve assembly, and the other end is connected to the drain pipe 42. The drain pipe 42 is connected to the drain valve assembly through the supporting portion 432, and the water forcibly discharged by the drain valve assembly is discharged out of the washing machine through the drain pipe. The washing machine also includes a ventilation device 5 arranged at the rear of the outer drum 1 to realize air circulation between the inside of the outer drum 1 and the outside of the outer drum 1, and the ventilation device 5 includes: an exhaust hole formed in the rear wall of the outer drum 1 and connected to the inside of the outer drum 1; an overflow pipe 51, one end of which is connected to the exhaust hole and the other end is connected to the drain pipe 42 to discharge the foam and water overflowing from the inside of the outer drum 1 out of the washing machine; a breathable pipe 52, one end of which is connected to the overflow pipe 51 and the other end extends to a position higher than the exhaust hole and is provided with a defoaming structure 521 for breaking the foam overflowing therein into liquid and directing it to the overflow pipe 51. The other end of the overflow pipe 51 is connected to the drain pipe 42 through the mounting structure 43, and specifically, the other end of the overflow pipe 51 is connected to the drain pipe 42 through the support portion 432. The drain valve assembly 41 is generally not arranged at the rear side of the outer drum 1 due to the limitations of factors such as shape and drainage position. When the drain pipe 42 is directly led out from the drain port of the drain valve assembly 41, the position of the drain pipe 42 will be forward, which is easy to shake and not beautiful. The drain pipe 42 leading out of the washing machine cannot be fixed. Therefore, a support portion 432 is provided to lead the water forced to be discharged by the drain valve assembly 41 to the drain pipe 42 through the support portion 432, and then discharged through the drain pipe 42, which also supports the drain pipe 42 and the drain valve assembly 41. At the same time, because the overflow pipe 51 is mostly led out from the top of the washing machine, extends downward along the rear side of the outer drum 1 to the drain pipe 42 to be discharged from the washing machine, if the support portion 432 is not provided, the overflow pipe 51 will be bent and connected to the drain pipe 42, which is easy to leave water or foam and cannot be completely discharged. Preferably, the other end of the support portion 432 is integrally formed with the mounting plate, and is detachably connected to the hanging ear 2 through the mounting plate. The overflow pipe 51 is arranged at the rear side of the outer tub 1, and the other end of the overflow pipe 51 close to the support part 432 is connected to the support part 432, and the other end of the drain pipe 42 close to the support part 432 is connected to the support part 432, that is, the position where the overflow pipe 51 is connected to the support part 432 is arranged near the hanging ear 2, and the position where the drain pipe 42 is connected to the transfer pipe 421 is also arranged near the hanging ear 2, the overflow pipe 51 is led out from the support part 432 and extends upward along the rear side of the outer tub 1, and the drain pipe 42 is led out from the support part 432 and extends downward to discharge water from the washing machine to the sewer. The support part 432 is equivalent to a three-way pipe.In a preferred embodiment, the support portion 432 serves to connect the drain valve assembly 41 and the drain pipe 42 , the overflow pipe 51 and the drain pipe 42 , and also serves to limit and support the drain valve assembly 41 and the drain pipe 42 .

[0107] Embodiment 3

[0108] like Figure 1-12 As shown, in the present embodiment, a wall-mounted washing machine is disclosed, which includes an outer drum 1, in which an inner drum is rotatably provided, and the outer drum 1 is directly mounted on the wall, eliminating the assembly structure between the outer drum 1 and the wall, thereby reducing the production and transportation costs of the washing machine, and also simplifying the assembly steps of the washing machine, reducing the difficulty of assembling the washing machine, and reducing the workload of the installer.

[0109] Furthermore, at least one radially outwardly protruding lug 2 is provided on the wall of the outer drum 1, and the lug 2 is attached to and fixedly connected to the wall. The outer drum 1 of the present invention is hung on the wall via the lug 2, and does not require components such as dampers for support, thereby reducing the number of components on the washing machine, thereby further reducing the production cost and assembly difficulty of the washing machine, while also reducing the overall size and weight of the washing machine, optimizing the appearance of the washing machine, and improving the reliability of the wall-mounted washing machine. Preferably, a lug 2 is provided at each of the four corners of the wall of the outer drum 1, and more preferably, the lug 2 is provided on two height planes.

[0110] Further, the wall is provided with a support member 3 extending in the direction of the outer cylinder 1, and the support member 3 passes through the hanging ear 2 and is supported by the hanging ear 2. The specific assembly steps of the outer cylinder 1 of the present invention are: firstly install the support member 3 on the wall, then hang the hanging ear 2 on the support member 3 to achieve the preliminary fixation of the outer cylinder 1, and finally screw the nut onto the support member 3 passing through the hanging ear 2, so that the hanging ear 2 is clamped and fixed on the support member 3 between the wall and the nut, thereby achieving the assembly of the outer cylinder 1. Preferably, a shock-absorbing gasket is clamped and fixed between the wall and the hanging ear 2, and between the hanging ear 2 and the nut, respectively, to reduce the noise generated by the washing machine during operation. It is also possible that the hanging ear 2 is fixedly connected to the wall by bolts, so that the hanging ear 2 is clamped and fixed on the screw screw between the bolt nut and the wall. Preferably, a shock-absorbing gasket is clamped and fixed between the wall and the hanging ear 2, and between the hanging ear 2 and the bolt nut, to reduce the noise generated by the washing machine during operation.

[0111] Embodiment 4

[0112] like Figure 1-12As shown, this embodiment discloses a wall-mounted washing machine, including an outer drum 1 directly mounted on the wall, a box installed on the outer periphery of the outer drum 1, and a drainage device 4, wherein the drainage device 4 includes: a drainage valve assembly 41, which is connected to the outer drum 1 and forcibly discharges the water in the outer drum 1; a drainage pipe 42, one end of which is connected to the drainage valve assembly 41, and the other end of which passes through the box below the end of the outer drum 1 close to the wall and extends to the outside of the washing machine.

[0113] In the above scheme, the wall-mounted washing machine is different from the ordinary drum washing machine which is placed on a plane. The wall-mounted washing machine is a washing machine that is hung on the wall for use. The wall-mounted washing machine of the present invention includes an outer drum 1 directly mounted on the wall, which does not require components such as dampers for support, reduces the number of components on the washing machine, thereby further reducing the production cost and assembly difficulty of the washing machine, while also reducing the overall size and weight of the washing machine and optimizing the appearance of the washing machine. The outer periphery of the side of the outer drum 1 includes a box body. The washing machine also includes a drainage device 4, which includes a drainage valve assembly 41 that forces the water in the outer drum 1 to be discharged from the outer drum 1 to the outside during the corresponding washing stage, and discharges the water forced to be discharged from the outer drum 1 to a drainage pipe 42 outside the washing machine. The drainage pipe 42 generally discharges the water to the outside of the washing machine through a hose, which is prone to vibration, collision, etc. and causes damage. In order to facilitate and thoroughly drain the water, the drainage pipe 42 generally extends from the top to a discharge port such as a floor drain on the ground. In order to facilitate the fixation of the drain pipe 42 and the overall aesthetics, and also to reduce the vibration of the drain pipe 42, the drain hose of an ordinary wall-mounted washing machine extends to the outside of the washing machine after passing through the rear panel. The drain hose passes through the rear panel to fix the hose. However, the sharp edges or rib structures that may exist on the edges of the holes on the rear panel may damage the hose when the hose vibrates, resulting in a high damage rate for the hose. Furthermore, for washing machines without a rear panel, the hose cannot be fixed and may fluctuate more. The drainage device 4 of the wall-mounted washing machine described in the present invention solves this problem. The other end of the drain pipe 42 passes through the box below the outer drum 1 and extends to the outside of the washing machine. Specifically, the other end of the drain pipe 42 passes through the box below the end of the outer drum 1 close to the wall and extends downward to the floor drain outside the washing machine. When the drain pipe 42 is arranged at the end of the outer drum 11 that is not close to the wall, the drain pipe 4242 is easily exposed to the outside and is not beautiful. In addition, the drain pipe 42 cannot be fixed during the connection with the floor drain, which will cause shaking and vibration, thereby causing damage to the drain pipe 42. Therefore, the other end of the drain pipe 42 in the present application passes through the box below the end of the outer drum 1 close to the wall and extends to the outside of the washing machine.

[0114] Furthermore, the drainage device 4 also includes a mounting structure 43, and the mounting structure 43 is configured to fix and support one end of a drainage pipe 42 on an end of the outer drum 1 close to the wall. One end of the drainage pipe 42 is connected to the drainage valve assembly 41 through the mounting structure 43, and the other end of the drainage pipe 42 passes through the box below the outer drum 1 and extends to the outside of the washing machine.

[0115] In the above scheme, the drainage device 4 also includes a mounting structure 43, which not only supports the drainage valve assembly 41 and the drainage pipe 42, but also fixes one end of the drainage pipe 42 to the end of the outer tube 1 close to the wall, and also serves to connect the drainage pipe 42 and the drainage valve assembly 41.

[0116] Furthermore, at least one hanging ear 2 protruding radially outward is provided on the wall of the outer cylinder 1, and the hanging ear 2 is attached to and fixedly connected to the wall surface, and the mounting structure 43 fixes and supports one end of the drain pipe 42 on the hanging ear 2.

[0117] Preferably, the mounting structure 43 detachably fixes and supports one end of the drain pipe 42 on the hanging ear 2 .

[0118] In the above scheme, the outer drum 1 of the present invention is hung on the wall through the hanging ear 2, and does not need to be supported by components such as dampers, thereby reducing the number of components on the washing machine, thereby further reducing the production cost and assembly difficulty of the washing machine, while also reducing the overall size and weight of the washing machine, optimizing the appearance of the washing machine, and improving the reliability of the wall-mounted washing machine. The drain pipe 42 is fixedly supported on the hanging ear 2 through the mounting structure 43, which not only sets the drain pipe 42 on the rear side of the outer drum 1, but also fixes it on the hanging ear 2, and also plays a role of limiting support for the drain valve assembly 41, preventing the occurrence of the problem that the drain pipe 42 cannot be fixed due to the lack of a rear panel in the present invention, thereby avoiding the shaking, vibration, damage, water splashing and other problems caused by the inability to fix the drain pipe 42. In order to facilitate the installation, maintenance, inspection, replacement and other operations of the drain pipe 42, the mounting structure 43 detachably supports one end of the drain pipe 42 on the hanging ear 2, and the other end of the drain pipe 42 passes through the box below the outer drum 1 and extends downward to the outside of the washing machine.

[0119] Furthermore, a hanging ear 2 is respectively provided at the four corners of the wall of the outer cylinder 1, and the mounting structure 43 detachably fixes one end of the drain pipe 42 on a hanging ear 2 on the lower side of the outer cylinder 1. Preferably, the hanging ear 2 is the hanging ear 2 on the lower side of the outer cylinder 1 closer to the drain valve assembly 41.

[0120] In the above scheme, a lug 2 is respectively provided at the four corners of the wall of the outer cylinder 1. In a preferred embodiment, the lug 2 is provided on two height planes. Further, a support member 3 extending toward the outer cylinder 1 is provided on the wall, and the support member 3 passes through the lug 2 and is supported by the lug 2. The specific assembly steps of the outer cylinder 1 of the present invention are: firstly install the support member 3 on the wall, then hang the lug 2 on the support member 3 to achieve the preliminary fixation of the outer cylinder 1, and finally screw the nut onto the support member 3 passing through the lug 2, so that the lug 2 is clamped and fixed on the support member 3 between the wall and the nut, thereby achieving the assembly of the outer cylinder 1. In a preferred embodiment, a shock-absorbing gasket is clamped and fixed between the wall and the lug 2, and between the lug 2 and the nut, so as to reduce the noise generated by the washing machine during operation. Alternatively, the lug 2 is fixedly connected to the wall by a bolt, so that the lug 2 is clamped and fixed on the screw between the bolt nut and the wall. In a preferred embodiment, a shock-absorbing gasket is clamped and fixed between the wall and the hanging ear 2, and between the hanging ear 2 and the bolt nut to reduce the noise generated by the washing machine during operation. The drain pipe 42 of the present invention is fixedly supported on a hanging ear 2 on the lower side of the outer cylinder 1 through a mounting structure 43, which is arranged both at the rear side of the outer cylinder 1 and at the lower side of the outer cylinder 1. Water can be discharged more conveniently without residue under the action of gravity, and the appearance is ensured, and the drain pipe 42 is fixedly supported. In a preferred embodiment, the drain pipe 42 is fixedly supported on a hanging ear 2 on the lower side of the outer cylinder 1 near the drain valve assembly 41 through a mounting structure 43, which simplifies the device, and simplifies the method and structure of the mounting structure 43 to fix and support the drain pipe 42.

[0121] Furthermore, the mounting structure 43 includes a supporting portion 432 supporting one end of the drain pipe 42. One end of the supporting portion 432 is connected to the drain valve assembly 41 to receive water discharged by the drain valve assembly 41, and the other end is connected to one end of the drain pipe 42 to discharge the water discharged by the drain valve assembly 41 out of the washing machine through the drain pipe 42. The drain pipe 42 is supported at one end of the outer drum 1 close to the wall by the supporting portion 432.

[0122] In the above scheme, the support part 432 supports one end of the drain pipe 42 at the end of the outer drum 1 close to the wall. While supporting the drain pipe 42 and the drain valve assembly 41, the two are also circulated, so that the water forced to be discharged from the drain valve assembly 41 can smoothly flow to the drain pipe 42 through the support part 432 and then be discharged from the washing machine through the drain pipe 42. The other end of the drain pipe 42 extends through the box to the outside of the washing machine to discharge the water outside the washing machine. The drain valve assembly 41 is generally limited by factors such as shape and drainage position, and cannot be set at the rear side of the outer drum 1. When the drain pipe 42 is directly led out of the drain port of the drain valve assembly 41, the position of the drain pipe 42 will be forward, which is easy to shake and not beautiful. The drain pipe 42 led out of the washing machine cannot be fixed. Therefore, the support part 432 is set to lead the water forced to be discharged from the drain valve assembly 41 to the drain pipe 42 through the support part 432, and then discharged through the drain pipe 42, and it also plays a supporting role for the drain pipe 42 and the drain valve assembly 41.

[0123] Furthermore, the support portion 432 is a tubular structure, one end of which is connected to the drain valve assembly 41, and the other end extends toward the end of the outer tube 1 close to the wall, connected to the drain pipe 42 and supports the drain pipe 42 at the end of the outer tube 1 close to the wall.

[0124] In the above scheme, the support portion 432 is a tubular structure having a hollow cavity for water to flow through. The drain valve assembly 41 and the drain pipe 42 are connected through the tubular structure and are respectively arranged at both ends of the tubular structure, which not only guides the water of the drain valve assembly 41 to the drain pipe 42, but also supports the drain valve assembly 41, and supports the drain pipe 42 at one end of the outer tube 1 close to the wall to facilitate the extension and fixation of the other end of the drain pipe 42.

[0125] Furthermore, the support portion 432 is a hard pipe and is disposed on the same horizontal plane as the drain valve assembly 41 .

[0126] In the above solution, the support part 432 is a hard pipe to support the drain pipe 42 and the drain valve assembly 41. A soft pipe cannot support the drain pipe 42 and the drain valve assembly 41. The support part 432 and the drain valve assembly 41 are arranged on the same horizontal plane, which has a simple structure, does not occupy much space, and is convenient for installation and maintenance.

[0127] Furthermore, the support portion 432 extends from the drain valve assembly 41 toward the end of the outer tube 1 close to the wall, and the connection point between the drain pipe 42 and the support portion 432 is lower than the connection point between the support portion 432 and the drain valve assembly 41 .

[0128] In the above solution, the support portion 432 extends from the drain valve assembly 41 to the end of the outer tube 1 close to the wall, so that the water in the support portion 432 flows out of the drain pipe 42 completely, without residue, and without backflow. The connection point between the drain pipe 42 and the support portion 432 is lower than the connection point between the support portion 432 and the drain valve assembly 41, so as to better drain the water in the support portion 432 and prevent water residue or backflow.

[0129] Furthermore, the washing machine further comprises an overflow pipe 51 for discharging the foam and water overflowing from the outer tub 1 out of the washing machine, and the overflow pipe 51 is connected to the drain pipe 42 through the support portion 432.

The other end of the overflow pipe 51 is connected to the drain pipe 42 through the support portion 432. Specifically, the other end of the overflow pipe 51 is connected to the drain pipe 42 through the support portion 432 at the end of the outer drum 1 close to the wall.

[0132] Embodiment 5

[0133] like Figure 1-12 As shown, this embodiment discloses a drain valve assembly 41, including: a motor for providing power to the drain valve assembly 41; a mounting shell 411, wherein the mounting shell 411 includes a cavity for accommodating the motor; and a sealing structure 412, which is arranged on the mounting shell 411 and is used to seal the cavity of the mounting shell 411.

[0134] In the above solution, the drain valve assembly 41 is provided with a motor that provides power for draining water, such as washing machine drainage, and motor protection is particularly important. A mounting housing 411 is provided to provide a cavity for accommodating the motor to prevent the motor from being damaged by 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 to prevent the motor from being damaged by water and water vapor.

[0135] Furthermore, the mounting shell 411 includes a first shell 4111 and a second shell 4112 , the first shell 4111 and the second shell 4112 are detachably connected, and the sealing structure 412 is disposed at the connection between the first shell 4111 and the second shell 4112 .

[0136] In the above solution, the installation housing 411 includes a detachably connected first housing 4111 and a second housing 4112, in order to facilitate the installation and maintenance of the motor. However, there is inevitably a gap between the two housings, and water / water vapor can enter the cavity of the installation housing 411 through the gap, causing damage to the motor. A sealing structure 412 is provided at the connection between the first housing 4111 and the second housing 4112, which solves the defect of water / water vapor entering between the two housings.

[0137] Furthermore, the sealing structure 412 includes a sealing portion 4121 arranged at the connection between the first shell 4111 / the second shell 4112, and a matching portion 4122 arranged at the connection between the second shell 4112 / the first shell 4111. The sealing portion 4121 and the matching portion 4122 cooperate to seal the connection between the first shell 4111 and the second shell 4112.

[0138] In the above solution, the sealing structure 412 includes a sealing portion 4121 and a matching portion 4122, the matching of which is convenient for installation and maintenance and can achieve a good sealing effect.

[0139] Furthermore, the connection between the first shell 4111 / the second shell 4112 includes connection end 5211 surfaces that are in mating contact with each other, the sealing portion 4121 is a protruding portion provided on the connection end 5211 surface of the first shell 4111 / the second shell 4112, and the matching portion 4122 is a groove portion provided on the connection end 5211 surface of the second shell 4112 / the first shell 4111.

[0140] Furthermore, the protrusion extends into the groove to limit and seal the connection end 5211 surface of the first shell 4111 and the second shell 4112 .

[0141] In the above scheme, the sealing portion 4121 is a protrusion protruding from the surface of the connection end 5211, and the matching portion 4122 is a groove portion arranged on the surface of the connection end 5211. The protrusion extends into the groove portion to limit and seal the connection end 5211 surface of the first shell 4111 and the second shell 4112, and the sealing effect is good, which completely prevents the possibility of water entering the interior of the installation shell 411. Water vapor needs to bypass the protrusion and the groove to enter the interior of the installation shell 411. In this process, the water vapor condenses into water after hitting the wall many times and cannot enter the cavity of the installation shell 411. It is equivalent to forming an N-type labyrinth water seal for water and water vapor, which greatly reduces the possibility of water and water vapor entering the cavity of the installation shell 411, and the sealing effect is good. In addition, the protrusion extending into the groove portion also plays a role in limiting installation, which provides a lot of convenience for the installation of the first shell 4111 and the second shell 4112.

[0142] Furthermore, the protrusion is a continuous protrusion-like structure arranged on the surface of the connection end 5211 of the first shell 4111 / the second shell 4112, and the groove is a continuous groove-like structure matched with the protrusion.

[0143] In the above solution, the protrusion is a continuous protrusion-shaped structure, which seals the entire surface of the connecting end 5211 and has a good sealing effect.

[0144] Furthermore, the cross-section of the protrusion along the extension direction is a rectangle, and the shapes and sizes of the groove portion and the protrusion match. Preferably, the corners of the rectangle away from the connection end 5211 are provided with rounded corners.

[0145] In the above solution, the cross section of the protrusion along the extension direction is rectangular, and the shape and size of the groove part match the protrusion part, so the sealing effect is good. In a preferred embodiment, the corners of the rectangle away from the connection end 5211 are rounded to prevent damage to the groove part during installation or removal.

[0146] Embodiment 6

[0147] like Figure 1-12 As shown, the present embodiment discloses a wall-mounted washing machine, comprising an outer drum 1, and also comprising a ventilation device 5 arranged at the rear of the outer drum 1 to realize air circulation between the inside of the outer drum 1 and the outside of the outer drum 1, wherein the ventilation device 5 comprises: an exhaust hole formed in the rear wall of the outer drum 1 and connected to the inside of the outer drum 1; an overflow pipe 51, one end of which is connected to the exhaust hole, and the other end discharges the foam and water overflowing from the inside of the outer drum 1 out of the washing machine; a ventilating pipe 52, one end of which is connected to the overflow pipe 51, and the other end extends to a position higher than the exhaust hole, and is provided with a defoaming structure 521 for breaking the foam overflowing thereto into liquid and directing it to the overflow pipe 51.

[0148] In the above scheme, the wall-mounted washing machine is different from the ordinary drum washing machine which is placed on a plane. The wall-mounted washing machine is a washing machine that is hung on the wall for use. The wall-mounted washing machine of the present invention includes a ventilation device 5 for realizing air circulation between the inside and outside of the outer drum 1 to prevent the danger of the outer drum 1 from exploding due to the inability to ventilate. The ventilation device 5 is arranged at the rear of the outer drum 1, which saves the side space of the outer drum 1 compared with being arranged at the side of the outer drum 1, reduces the volume of the wall-mounted washing machine, and the ventilation device 5 can be arranged between the rib structures of the rear wall of the outer drum 1, and does not occupy much space on the rear wall of the outer drum 1. The ventilation device 5 includes an exhaust hole connected to the inside of the outer drum, and the exhaust hole is arranged on the rear wall of the outer drum 1, so that the overflow pipe 51 is conveniently connected to the rear wall of the outer drum 1. The ventilation device 5 also includes an overflow pipe 51 to discharge the foam and water overflowing from the outer drum 1 out of the washing machine. One end of the overflow pipe 51 is connected to the exhaust hole arranged above the rear wall of the outer drum 1, and the other end is connected to the drainage device 4, so that the foam and water overflowing from the top of the outer drum 1 are discharged out of the washing machine through the drainage device 4. The ventilation device 5 also includes an air vent 52 for the circulation of air between the inside and outside of the outer drum 1. One end of the air vent 52 is connected to the overflow pipe 51, and is connected to the inside of the outer drum 1 through the overflow pipe 51, and the other end is connected to the outside of the outer drum 1 to achieve air circulation between the inside and outside of the outer drum 1. The other end of the air vent 52 extends to a position higher than the exhaust hole to prevent foam from directly overflowing from the air vent 52. The other end of the air vent 52 extends to a position higher than the exhaust hole. The pressure required for the foam to overflow from the air vent is greater, thereby greatly reducing the possibility of foam overflow. The other end of the air vent 52 is also provided with a defoaming structure 521 for breaking the foam overflowing therein into liquid and directing it to the overflow pipe. The defoaming structure 521 prevents the foam from overflowing from the air vent 52 and overflowing the washing machine, and does not affect the ventilation function of the air vent 52.

[0149] Further, the exhaust hole is arranged at the highest water level inside the outer cylinder 1 . Preferably, the exhaust hole is arranged on the diameter of the axis vertically passing through the rear wall of the outer cylinder 1 , and is connected to the highest water level inside the outer cylinder 1 .

[0150] In the above scheme, the exhaust hole is set at the highest water level inside the outer tube 1, so as to avoid the accidental overflow of foam and water caused by the exhaust hole being set at a lower position, thereby causing problems such as unclean washing. In a preferred embodiment, the exhaust hole is set on the diameter of the axis that vertically passes through the rear wall of the outer tube 1, which makes it easier to find and determine the highest water level. Compared with the exhaust holes set at other positions, it increases the difficulty of foam overflowing while achieving the function of overflowing foam and water when there are too much foam and water.

[0151] Furthermore, the washing machine also 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 circumference of the rear wall of the outer drum 1 and is connected to the drainage device 4. Preferably, the overflow pipe 51 extends downward along the circumference close to the axis of the rear wall of the outer drum 1. More preferably, one end of the overflow pipe 51 extends downward from the exhaust hole in the vertical direction for a distance and then extends downward along the circumference close to the axis of the rear wall of the outer drum 1.

[0152] In the above scheme, the washing machine also includes a drainage device 4 for discharging the washing water in the outer drum 1 out of the washing machine. One end of the overflow pipe 51 is connected to the exhaust hole to realize air circulation inside and outside the outer drum, and the other end is connected to the drainage device 4, so that the foam and water overflowing from the exhaust hole are discharged out of the washing machine through the drainage device 4. In addition, the other end of the overflow pipe 51 extends downward along the circumference of the rear wall of the outer drum 1 to avoid excessive disturbance of the layout of the ribs on the rear wall of the outer drum 1. It is arranged between the ribs without occupying space and interrupting the distribution of the ribs. In a preferred embodiment, the overflow pipe 51 extends downward along the circumference close to the axis of the rear wall of the outer drum 1 to reduce the length of the overflow pipe 51, so that the foam and water can be discharged faster, avoiding the foam overflow caused by the accumulation of foam. At the same time, the closer to the axis, the greater the vibration, and the easier it is for the foam to break and flow out. In a more preferred embodiment, one end of the overflow pipe 51 extends downward from the exhaust hole in the vertical direction for a distance, and then extends downward along the axial direction close to the axis of the rear wall of the outer cylinder. The overflow pipe 51 extending downward in the vertical direction makes it easier for foam and water to flow to the drainage device 4.

[0153] Furthermore, one end of the air pipe 52 is connected to the overflow pipe 51, and the other end extends upward along the rear wall of the outer tube 1 to a position higher than the exhaust hole. Preferably, the air pipe 52 is close to the overflow pipe 51, and the other end of the air pipe 52 extends upward along the circumferential direction of the rear wall of the outer tube 1. More preferably, the other end of the air pipe 52 extends circumferentially along the rear wall of the outer tube 1 and then continues to extend upward in the vertical direction to a position higher than the exhaust hole.

[0154] In the above scheme, the air vent 52 extends upward along the rear wall of the outer drum 1. On the one hand, the air vent 52 is arranged on the rear wall of the outer drum 1. The vibration of the rear wall of the outer drum 1 is relatively large, and the air vent 52 arranged on the rear wall of the outer drum 1 also vibrates relatively large, and the foam is more easily broken into liquid under the action of vibration; on the other hand, the air vent 52 extends upward along the rear wall of the outer drum 1, which saves space on the side wall of the outer drum 1 compared to being arranged on the side wall of the outer drum 1, and reduces the volume of the washing machine. When arranged on the rear wall of the outer drum 1, the air vent 52 can be embedded between the ribs on the rear wall of the outer drum 1 to save space; in addition, the other end of the air vent 52 extends to a position higher than the exhaust hole, and the pressure required for the foam to overflow from the air vent 52 is greater, thereby greatly reducing the possibility of foam overflow. In a preferred embodiment, the air vent 52 is close to the overflow pipe 51, and the other end of the air vent 52 extends upward along the circumferential direction of the rear wall of the outer cylinder 1. On the one hand, it avoids excessively disturbing the layout of the ribs on the rear wall of the outer cylinder 1, and is set between the ribs without occupying space and interrupting the distribution of the ribs. On the other hand, the air vent 52 is close to the overflow pipe 51, that is, close to the axis of the rear wall of the outer cylinder 1. The closer to the axis, the greater the vibration, the easier it is for the foam to be broken by vibration in the air vent, and it is less likely to overflow from the air vent 52. In a more preferred embodiment, the other end of the air vent 52 extends along the circumferential direction of the rear wall of the outer cylinder 1 and then continues to extend upward in the vertical direction to a position higher than the exhaust hole. The circumferential extension causes the foam to break when the vibration increases, and the continued upward extension in the vertical direction increases the upward resistance of the foam, and the end of the other end of the air vent 52 is more likely to be set higher than the exhaust hole.

[0155] Furthermore, a bending portion 522 is provided in the air permeable tube 52, and the bending portion 522 is arranged at one end connected to the overflow pipe 51. Preferably, the end of the air permeable tube 52 connected to the overflow pipe 51 is arranged below the horizontal line passing through the axis of the rear wall of the outer cylinder 1.

[0156] In the above scheme, a bending portion 522 is provided, which has the effect of breaking the overflowed foam and preventing overflow. It is arranged at one end of the overflow pipe 51. On the one hand, the bending portion 522 is used to transition the extension of the vent pipe 52, providing sufficient space for the upward extension of the vent pipe 52, and preventing the vent pipe 52 from extending upward beyond the range of the rear part of the outer tube 1 without space to continue to extend. On the other hand, the bending portion 522 is used to break the foam. When the foam is at the position where the pipeline is bent, a part of the foam will be broken under the increased pressure. The bending portion 522 also increases the pressure for the foam to move in the vent pipe 52, making it more difficult for the foam to flow in the vent pipe 52. Therefore, the bending portion 522 has both the transition effect and the effect of preventing overflow and breaking the foam. One end of the vent pipe 52 connected to the overflow pipe 51 is arranged below the horizontal line passing through the axis of the rear wall of the outer tube 1, which increases the difficulty of the foam overflowing to the overflow pipe 51. The resistance of the foam continuing to flow downward is less than the resistance of the foam flowing upward from the vent pipe 52, which effectively reduces the overflow of the foam.

[0157] Furthermore, the bending portion 522 is a protruding section protruding radially outward along the rear wall of the outer cylinder 1. Preferably, the protruding section is arc-shaped. More preferably, the protruding section is at least partially arranged below a horizontal line passing through the axis of the rear wall of the outer cylinder 1.

[0158] In the above scheme, the bending portion 522 is a protruding section that protrudes radially outward along the rear wall of the outer cylinder 1. The foam overflows upward from the overflow pipe 51 into the air vent pipe 52. The protruding section that protrudes radially outward, on the one hand, extends the stroke of the foam, increases the complexity of the stroke, and increases the resistance of the foam to continue to overflow upward. On the other hand, the protruding section that protrudes radially outward includes a first extension section extending radially outward and a second extension section extending radially inward. The vibration effect on the foam in the first extension section changes from large to small, and the vibration effect on the foam in the second extension section changes from small to large. The foam will gradually be burst under the changing vibration effect in the process of rising from the first extension section to the second extension section. Furthermore, the foam will change due to the vibration effect, rising resistance and rising route in the process of rising from the first extension section to the second extension section. The bubbles collide with each other, which makes it easier to burst the foam. In a preferred embodiment, the protruding section is arc-shaped, and the arc-shaped protruding section forms a structure similar to a semicircle, which can realize the function of a bending section on the one hand, and on the other hand, such a degree of bending is easy to form or easy to bend for a hose, does not increase the forming cost, and is easy to install. In a more preferred embodiment, the protruding section is at least partially arranged below the horizontal line passing through the axis of the rear wall of the outer tube 1, so that it is more difficult for the foam to overflow to the overflow pipe 51, and the resistance of the foam to continue to flow downward is less than the resistance of the air permeable pipe 52 upward, which effectively reduces the overflow of the foam.

[0159] Furthermore, the defoaming structure 521 is detachably arranged at the other end of the air-permeable tube 52 .

[0160] In the above scheme, the defoaming structure 521 is detachably arranged at the other end of the air tube 52, which is convenient for the installation, maintenance and cleaning of the defoaming structure 521, and avoids the other end of the air tube 52 being blocked by cotton wool and other debris due to the installation of the defoaming structure 521, thereby affecting ventilation.

[0161] Furthermore, the defoaming structure 521 includes a tubular body, and the tubular body includes:

[0162] A connecting end 5211 is provided at one end of the tubular body, and the tubular body is detachably provided at the other end of the vent tube 52 through the connecting end 5211. Preferably, threads are provided on the outside of the connecting end 5211 and the inside of the other end of the vent tube 52, and the tubular body is rotatably connected to the inside of the other end of the vent tube 52 through the threads;

[0163] The defoaming end 5212 is arranged at the other end of the tubular body, and the inner diameter of the tube of the connecting end 5211 is smaller than the inner diameter of the tube of the defoaming end 5212 .

[0164] In the above scheme, the connecting end 5211 is mainly used to detachably set the defoaming structure 521 at the other end of the air tube 52. The connecting end 5211 can be connected to the other end of the air tube 52 by means of snap-on or threaded connection. In the threaded connection method, there are two threaded connection methods: the inside of the connecting end 5211 and the outside of the other end of the air tube 52 are provided with threads, or the outside of the connecting end 5211 and the inside of the other end of the air tube 52 are provided with threads. In a preferred embodiment, the outside of the connecting end 5211 and the inside of the other end of the air tube 52 are both provided with threads, and the tubular body is optionally connected to the inside of the other end of the air tube 52 through the threads. The connecting end 5211 is set inside the other end of the air tube 52, which reduces the inner diameter and also plays a certain role in preventing foam overflow. The inner diameter of the tube of the connecting end 5211 is smaller than the inner diameter of the tube of the defoaming end 5212, which is equivalent to the presence of a necking portion of the connecting end 5211 in the air permeable tube 52. When the foam reaches the necking portion of the connecting end 5211, it is subjected to pressure due to the necking. Part of the foam ruptures under the pressure and does not continue to move toward the defoaming end 5212, while the other part of the foam continues to move toward the defoaming end 5212 and is intercepted and ruptured by the defoaming end 5212.

[0165] Furthermore, the defoaming end includes at least one defoaming plate 5213, and the defoaming plate 5213 extends radially and axially inside the defoaming end 5212 respectively. A gap for air permeability is provided between the defoaming plate 5213 and the inner wall of the tubular body and / or between the defoaming plates 5213. Preferably, the defoaming plate 5213 extends from the junction of the connecting end 5211 and the defoaming end 5212 to the end of the defoaming end 5212. More preferably, the defoaming plate 5213 is integrally formed inside the defoaming end 5212.

[0166] In the above scheme, the defoaming end includes a defoaming plate 5213 to prevent the foam from overflowing. The defoaming plate 5213 is radially arranged in the middle of the defoaming end 5212 and then extends axially. In a preferred embodiment, the defoaming plate 5213 extends axially to the junction of the defoaming end 5212 and the connecting end 5211. When the foam overflows from the connecting end 5211 to the defoaming end 5212, a part of it is first squeezed and broken by the neck of the connecting end 5211, and the remaining part is squeezed and broken again by the defoaming plate 5213 after being squeezed, and no foam will overflow from the defoaming end 5212. The gap between the defoaming plate 5213 and the inner wall is a gap for ventilation, so that the defoaming structure 521 can prevent the foam from overflowing while realizing the ventilation function of the ventilation tube 52. The anti-overflow part includes at least two defoaming plates 5213, which are arranged parallel to or crosswise with each other, and there are air-permeable gaps between the defoaming plates 5213 and between the defoaming plates 5213 and the inner wall of the defoaming end 5212. When the foam overflows from the connection end 5211 to the defoaming end 5212, a part of it is first squeezed and broken by the neck of the connection end 5211, and the remaining part is squeezed and broken again by the defoaming plate 5213 after being squeezed, so that no foam will overflow from the defoaming end 5212. The integrally formed defoaming plate 5213 saves processing and installation steps, saves costs, and is easy to use.
