[0082] Furthermore, the mounting cover plate 621 includes a fixing portion 6211 that cooperates with the water inlet end of the water diversion pipeline 61 to fix the water inlet end of the water diversion pipeline 61, and also includes a connecting portion 6212 that sets the fixing portion 6211 on the base / hanging ear 2.

[0083] Preferably, the connecting portion 6212 detachably sets the fixing portion 6211 on the base / hanging ear 2.

[0084] In the above scheme, the fixing part 6211 is used to fix the water inlet end of the water diversion pipeline 61, and the connecting part 6212 is used to fix the fixing part 6211. The connecting part 6212 and the fixing part 6211 can be integrally formed, or can be detachably connected or connected by other means. Preferably, the connecting part 6212 and the fixing part 6211 are integrally formed, which has a simple structure and saves costs. The connecting part 6212 can fix the fixing part 6211 on the base / hanging ear 2, for example, by integral molding or welding, or the fixing part 6211 can be detachably set on the base / hanging ear 2. The preferred embodiment is that the connecting part 6212 detachably sets the fixing part 6211 on the base / hanging ear 2, which is convenient for installation and disassembly and maintenance, and also convenient for installation, disassembly or replacement and maintenance of the water diversion pipeline 61.

[0085] Furthermore, the fixing portion 6211 is a plate-like structure bent in a semicircular arc shape, and the fixing portion 6211 cooperates with the base / hanging ear 2 to form a closed cavity for the water inlet end of the water diversion pipeline 61 to pass through.

[0086] Preferably, the shape of the fixing portion 6211 matches the shape of the water inlet end of the water diversion pipeline 61 , and the closed cavity at least partially matches the shape of the water inlet end of the water diversion pipeline 61 .

[0087] In the above scheme, it is curved in a semicircular arc shape, and the arc part protrudes from the base / hanging ear 2 to prevent the sharp edge of the surface of the fixing part 6211 from damaging other parts; the closed cavity is formed to achieve a good fixing effect, and prevent the water inlet end of the water diversion pipeline 61 from escaping from the opening or getting stuck at the opening to damage the water inlet end of the water diversion pipeline 61 when an opening is provided. In a preferred embodiment, the shape of the fixing part 6211 matches the shape of the water diversion pipeline 61 to prevent damage to the water inlet end of the water diversion pipeline 61.

[0088] Furthermore, the connecting portion 6212 is a plate-like structure extending from the end where the fixing portion 6211 contacts the base / hanging ear 2 to the outside of the closed cavity, and a through hole is provided on the connecting portion 6212, through which a screw passes to detachably connect the connecting portion 6212 to the base / hanging ear 2.

[0089] In the above solution, the connection part 6212 extends from the end of the fixing part 6211 that contacts the base / hanging ear 2 to the outside of the closed cavity, does not affect the shape of the fixing part 6211 itself, does not occupy space, and has no protruding structure that will damage other parts. The connection part 6212 is connected by screws, which is simple, convenient, and firmly installed.

[0090] Furthermore, the fixing structure 62 further includes a matching guide portion 622 disposed on the base / hanging ear 2, wherein the matching guide portion 622 includes a matching groove for matching with the fixing portion 6211 to fix the water inlet end of the water diversion pipeline 61, and a guide groove for guiding the water inlet end of the water diversion pipeline 61 to extend toward the upper side of the outer tube 1.

[0091] Preferably, the matching groove and the guide groove are grooves on the base / hanging ear 2 that are recessed toward the wall.

[0092] In the above scheme, a matching guide portion 622 is provided so that the water inlet end of the water diversion pipeline 61 is fixed more firmly and does not damage the water inlet end of the water diversion pipeline 61. Providing a matching groove can save space and reduce the size of the fixing portion 6211. Providing a guide groove guides the subsequent extension of the water inlet end of the water diversion pipeline 61 to prevent the water inlet end of the water diversion pipeline 61 from deviating and causing damage and inconvenience, while not occupying space. The matching groove and the guide groove are grooves on the base / hanging ear 2 that are recessed toward the wall and do not occupy space. The grooves also increase the strength of the base / hanging ear 2.

[0094] In the above solution, a limiting support part 623 is provided to play the role of limiting and supporting the water diversion pipeline 61 to prevent the water diversion pipeline 61 from being misplaced or stuck between the base / hanging ear 2 and the lower box.

[0095] Embodiment 3

[0096] like Figure 1-9 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:

[0097] The drain valve assembly 41 is connected to the outer tube 1 and forced to drain the water in the outer tube 1;

[0098] 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;

[0099] 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.

[0100] 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.

[0101] 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 .

[0102] 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, and the drain pipe 42 and the overflow pipe 51 are fixedly supported on the hanging ear 2 through the mounting structure 43.

[0103] 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.

[0104] 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 .

[0105] 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 via the ear 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. 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 bolts, 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] Furthermore, the mounting structure 43 includes:

[0110] 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;

[0111] 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;

[0112] Preferably, the mounting portion 431 and the supporting portion 432 are integrally formed.

[0113] 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.

[0114] 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 .

[0115] 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.

[0116] 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.

[0117] Preferably, the support portion 432 is a hard pipe, and is arranged on the same horizontal plane as the drain valve assembly 41.

[0118] 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 .

[0119] 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.

[0120] 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.

[0121] Preferably, the corners of the mounting plate are smoothly rounded.

[0122] 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.

[0123] Furthermore, the mounting portion 431 further includes a limiting portion 4312 connected to the limiting mounting plate.

[0124] Preferably, the limiting portion 4312 is integrally formed on the side of the mounting plate.

[0125] More preferably, the limiting portion 4312 includes a protrusion that continues to extend from the side of the mounting plate.

[0126] 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.

[0127] 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.

[0128] 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 .

[0129] 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.

[0136] The specific assembly steps of the outer cylinder 1 of the present invention are as follows: first, the support member 3 is installed on the wall, and then the hanging ear 2 is hung on the support member 3 to achieve preliminary fixation of the outer cylinder 1, and finally the nut is screwed 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.

[0137] Preferably, shock-absorbing gaskets are 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.

[0138] Alternatively, the hanging ear 2 is fixedly connected to the wall via bolts, so that the hanging ear 2 is clamped and fixed on the 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.

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.

[0145] Furthermore, the exhaust hole is arranged at the highest water level inside the outer tube 1.

[0146] 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 communicated with the highest water level inside the outer cylinder 1 .

[0147] 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.

[0148] Furthermore, the washing machine further comprises 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.

[0149] Preferably, the overflow pipe 51 extends downward along the circumferential direction close to the axis of the rear wall of the outer cylinder 1.

[0150] 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 circumferential direction close to the axis of the rear wall of the outer tube 1.

[0151] 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.

[0152] Furthermore, one end of the air vent 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.

[0153] Preferably, the air vent pipe 52 is close to the overflow pipe 51, and the other end of the air vent pipe 52 extends upward along the circumferential direction of the rear wall of the outer cylinder 1.

[0154] More preferably, the other end of the air-permeable tube 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.

[0155] 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.

[0156] 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 tube 51.

[0157] Preferably, one end of the air permeable pipe 52 communicating with the overflow pipe 51 is arranged below a horizontal line passing through the axis of the rear wall of the outer cylinder 1 .

[0158] 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.

[0159] Furthermore, the bending portion 522 is a protruding section protruding radially outward along the rear wall of the outer tube 1.

[0160] Preferably, the protruding section is arc-shaped.

[0161] 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 .

[0162] 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.

[0163] Furthermore, the defoaming structure 521 is detachably arranged at the other end of the air-permeable tube 52 .

[0164] 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.

[0165] Furthermore, the defoaming structure 521 includes a tubular body, and the tubular body includes:

[0166] 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;

[0167] 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 .

[0168] 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.

[0169] Further, 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 ventilation is provided between the defoaming plate 5213 and the inner wall of the tubular body and / or between the defoaming plates 5213.

[0170] 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.

[0171] More preferably, the defoaming plate 5213 is integrally formed inside the defoaming end 5212 .

[0172] 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.
