In other words, in the radial direction of the fixing panel 81, the extension length of a portion of the guide 83 may be gradually increased from front to rear, or the extension length of the guide 83 as a whole may be gradually increased from front to rear.

When the fixing panel 81 can be connected to a wall body during installation, then the box 82 is assembled from front to back, the guide piece 83 can provide guide for the box 82 in the process of assembling the box 82, the inner wall surface of the box 82 is contacted with the front end of the guide piece 83 firstly, then moves backwards to achieve matching, in the process, the guide piece 83 provides guide function for the box 82, the box 82 is conveniently assembled on the fixing panel 81, and the assembly efficiency of the box 82 and the fixing panel 81 can be improved. Moreover, the guide member 83 is used for guiding the box 82, so that the box 82 and the fixed panel 81 can be positioned easily, and the assembly accuracy can be improved.

According to the case assembly 600 of the wall-mounted washing machine 1000 of the embodiment of the invention, the guide 83 is arranged on the fixed panel 81, and the guide 83 is positioned between the inner wall surface of the case 82 and the outer wall surface of the fixed panel 81, so that the guide 83 can be used for guiding the case 82, thereby facilitating positioning, facilitating assembly, and improving assembly efficiency and assembly accuracy.

According to some embodiments of the present invention, as shown in fig. 2-6, the case assembly 600 may further include: a baffle 84, the baffle 84 may be provided on an outer wall surface of the fixing panel 81, the guide 83 may be located at a front side of the baffle 84, and the guide 83 may be connected to the fixing panel 81 and the baffle 84, respectively. Therefore, the inner end of the guide 83 can be connected with the fixing panel 81, the rear end of the guide 83 can be connected with the baffle 84, the baffle 84 can improve the strength of the guide 83 to a certain extent, the guide 83 is prevented from being damaged during assembly and use, and the reliability can be improved.

Alternatively, as shown in fig. 3 and 4, the guide 83 may be formed as a guide plate, and the guide 83 may include: a guide connection portion 831 and a guide portion 832. Wherein, the guide connection portion 831 may be connected to the fixing panel 81 and the barrier 84, respectively, and an extension length of the guide connection portion 831 in the radial direction of the fixing panel 81 may remain unchanged, the guide portion 832 may be located at a front side of the guide connection portion 831, and the guide portion 832 may be connected to the guide connection portion 831 and the fixing panel 81, respectively, and an extension length of the guide portion 832 in the radial direction of the fixing panel 81 may be gradually increased from front to rear. Thus, the guide portion 832 can provide a guide effect for the case 82, and the guide connecting portion 831 can connect the guide portion 832 and the baffle 84, not only can improve strength, but also can provide a guide effect.

For example, in the example shown in fig. 4, the rear side wall of the guide connection portion 831 is connected to the barrier 84, the inner side wall of the guide connection portion 831 is connected to the fixing panel 81, the outer side wall of the guide connection portion 831 is formed in a plane parallel to the inner side wall of the guide connection portion 831, the rear side wall of the guide portion 832 is connected to the front side wall of the guide connection portion 831, the inner side wall of the guide portion 832 is connected to the fixing panel 81, and the outer side wall of the guide portion 832 is formed in a slope inclined from front to rear to outside.

Alternatively, as shown in fig. 3 and 4, the rear outer end surface of the guide portion 832 is flush with the outer end surface of the guide connection portion 831, and has a simple and compact structure, and is convenient to manufacture.

Alternatively, the baffle 84 may be formed as an annular baffle 84 extending in the circumferential direction of the fixing panel 81, on the one hand, the strength of the guide 83 may be increased, the probability of damage to the guide 83 may be reduced, and on the other hand, the aesthetic appearance of the case assembly 600 may also be improved.

Further, as shown in fig. 3 and 4, the rear outer end surface of the guide 83 may be flush with the outer circumferential edge of the barrier 84, i.e., as shown in fig. 3 and 4, the outer side surface of the guide connecting portion 831 is located in the same plane as the outer circumferential surface of the barrier 84. Therefore, the structure is simple and compact, and the processing and the assembly are convenient.

According to some embodiments of the present invention, as shown in fig. 5 and 6, the baffle 84 is spaced from the rear side of the fixing surface, and the case assembly 600 further includes: an annular seal member 85, the seal member 85 may be provided between the fixing panel 81 and the case 82, and the seal member 85 may be located at the rear side of the barrier 84. Thereby, the seal 85 can seal the gap between the fixing panel 81 and the case 82 in the circumferential direction to prevent water leakage, and the baffle 84 can provide a stopper for the seal 85 to prevent dislocation of the seal 85 and improve the sealing effect.

Alternatively, the sealing member 85 may be a sealing sponge strip, which has a simple structure, is convenient to assemble, and has a good sealing effect and low cost.

According to some embodiments of the present invention, the ratio k of the front end length to the rear end length of the guide 83 in the radial direction of the fixing panel 81 may satisfy: k is 0.2 < 1 to improve the strength of the guide 83 and provide a reliable guide for the case 82. For example, in the example shown in fig. 3 and 4, the ratio k=0.5 of the front end length to the rear end length of the guide 83. Of course, the structure of the present invention is not limited thereto, and the ratio k of the front end length to the rear end length of the guide 83 is not limited to the description in the above example, but may take other values, for example, 0.2, 0.4, 0.9, etc. As will be appreciated by those skilled in the art, this will not be described in detail herein.

According to some embodiments of the present invention, as shown in fig. 2 to 4, the guide 83 may be plural, and the plural guide 83 may be disposed at intervals along the circumference of the fixing panel 81, so that the case 82 may be guided from plural positions by the plural guide 83, positioning and assembling may be more convenient, and assembling efficiency and assembling accuracy may be effectively improved.

Alternatively, the fixing panel 81, the guide 83 and the baffle 84 may be integrally formed, so that the structure is simple, the cost is low, and seamless connection of the fixing panel 81, the guide 83 and the baffle 84 may be realized, so that the guide 83 has sufficient strength, and stability, reliability and aesthetic property of the wall-mounted washing machine 1000 are improved.

As shown in fig. 1, a wall-mounted washing machine 1000 according to an embodiment of the present invention includes a cabinet assembly 600 and a tub assembly according to the above-described embodiments of the present invention, wherein the tub assembly is provided on a fixed panel 1 and is located in a mounting chamber 101.

Accordingly, according to the wall-mounted washing machine 1000 of the embodiment of the present invention, by providing the cabinet assembly 600 according to the above-described embodiment of the present invention, the assembly is facilitated, and the assembly efficiency and the assembly accuracy can be improved.

As shown in fig. 1, 2 and 5, the tub assembly includes a rear tub 400, and the rear tub 400 may be integrally injection-molded to the fixing panel 81, so that connection reliability may be further improved, and stability and safety of the wall-mounted washing machine 1000 may be improved.

In some embodiments of the present invention, the wall-mounted washing machine 1000 further includes an overflow exhaust assembly 100, and as shown in fig. 7 to 20, the overflow exhaust assembly 100 of the washing machine according to an embodiment of the present invention includes an overflow pipe 10 and an exhaust assembly 20.

One end of the overflow pipe 10 is adapted to be connected to the tub rear outer tub 400 of the washing machine, and the other end of the overflow pipe 10 is in communication with the outside, such that the tub rear outer tub 400 of the washing machine forms a flow path with the outside through the overflow pipe 10, and when the water level in the tub rear outer tub 400 is excessively high or the foam is excessively high, the foam and water can be discharged through the flow path formed by the overflow pipe 10.

The exhaust assembly 20 is formed in a bent structure having a bent structure, one side of the exhaust assembly 20 is connected to the overflow pipe 10, and a pipe section bent structure of one side of the exhaust assembly 20 connected to the overflow pipe 10 is not lower than a connection between the exhaust assembly 20 and the overflow pipe 10 in an up-down direction, that is, a connection between the overflow pipe 10 and the exhaust assembly 20 is not higher than a pipe section of the exhaust assembly 20 directly connected to the overflow pipe 10 at a position where the bent structure is located in the up-down direction. In this way, the overflowed water in the rear tub 400 does not enter the exhaust assembly 20 through the overflow pipe 10, thereby ensuring a smooth flow path in the exhaust assembly 20.

When the foam is too much in the rear tub 400 of the washing machine and the flow path of the overflow pipe is too long, the flow resistance of the foam is increased, and when a part of the foam is not discharged, the foam is introduced into one side pipe section of the air discharge assembly 20 directly connected to the overflow pipe 10, and then slowly rises to the bending structure, and is mostly broken by extrusion in the bending structure, and at the same time, a small amount of foam may be introduced into the other side pipe section of the air discharge assembly 20 (i.e., positioned at the other side of the bending structure of the air discharge assembly 20) through the bending structure, at this time, the foam in the overflow pipe 10 is discharged to the outside, and at this time, a negative pressure is formed in the air discharge assembly 20, and the foam instantaneously flows back into the overflow pipe 10 and is discharged to the outside under the siphon effect.

Therefore, by arranging the bent exhaust assembly 20 which is connected with the overflow pipe 10 and has a bent structure, and arranging the pipe section on one side of the bent structure, which is connected with the overflow pipe 10, of the exhaust assembly 20 to be not lower than the joint of the overflow pipe 10 and the exhaust assembly 20 in the up-down direction, excessive foam discharged from the rear outer tub 400 of the washing machine gradually rises to the bent structure air pipe adapter 23 after entering the exhaust assembly 20, and breaks at the bent structure air pipe adapter 23 in a large amount, thereby achieving the foam-killing effect, and then, not only can air pressure balance be formed inside and outside the rear outer tub 400, but also external pollution of the washing machine caused by overflow of foam in the rear outer tub 400 can be avoided.

As shown in fig. 7, according to an embodiment of the present invention, the exhaust assembly 20 is mainly composed of a first exhaust pipe 21 and a second exhaust pipe 22, one end of the first exhaust pipe 21 is connected to the overflow pipe 10 and extends upward substantially in a vertical direction (up-down direction as shown in fig. 7), one end of the second exhaust pipe 22 is connected to the other end of the first exhaust pipe 21, the other end of the second exhaust pipe 22 extends downward to form an exhaust end 24 that is in communication with the outside, and a junction of the first exhaust pipe 21 and the second exhaust pipe 22 is formed in a bent structure in a bent shape.

Specifically, when the foam in the rear tub 400 of the washing machine is not discharged until it is increased in flow resistance, a portion of the foam is introduced into the first exhaust duct 21, then slowly rises into the bent air duct adapter 23, and is mostly broken by being pressed by the inner wall surface in the bent air duct adapter 23, thereby achieving the effect of foam removal, even though a small amount of foam may continue into the second exhaust duct 22, since the foam and water in the overflow duct 10 have been discharged to the outside at this time, negative pressure is formed in the first and

second exhaust ducts

21 and 22, and the foam instantaneously flows back into the overflow duct 10 under the siphon effect, and is discharged to the outside.

As shown in fig. 14 to 17, in an example of the present invention, the bending structure may be a gas pipe adaptor 23, and the first exhaust pipe 21 and the second exhaust pipe 22 are connected through the gas pipe adaptor 23, so that the foam entering the first exhaust pipe 21 is greatly broken by being extruded from the inner wall surface of the gas pipe adaptor 23 when flowing to the gas pipe adaptor 23, thereby achieving a foam-extinguishing effect and balancing the air pressure of the rear outer tub 400.

As shown in fig. 14 to 17, in a further example of the present invention, the air pipe adaptor 23 is formed in a substantially herringbone structure, the air pipe adaptor 23 is mainly composed of a first connection portion 231, a second connection portion 232 and a foam-removing portion 233, the foam-removing portion 233 is located above the first connection portion 231 and the second connection portion 232, the first connection portion 231 communicates with the upper end of the first exhaust pipe 21, the second connection portion 232 communicates with the upper end of the second exhaust pipe 22, the first exhaust pipe 21, the second exhaust pipe 232 and the foam-removing portion 233 communicate with each other, so that after the foam entering the first exhaust pipe 21 rises to the first connection portion 231, the foam gradually enters the foam-removing portion 233 and is broken by the inner wall in the foam-removing portion 233, thereby achieving the foam-removing effect, even if a part of the foam is not broken and enters the second connection portion 232 and then enters the second exhaust pipe 22, but at this time, since the foam and water in the overflow pipe 10 have been discharged to the outside at this time, negative pressure is formed in the first exhaust pipe 21 and the second exhaust pipe 22, the foam is instantaneously discharged to the outside under the backflow effect.

As shown in fig. 16 and 17, in a further example, the top of the foam-extinguishing portion 233 is sealed so that a foam-pressing chamber can be formed in the foam-extinguishing portion, thereby enhancing the pressing action of the foam entering therein and improving the foam-extinguishing effect.

As shown in fig. 7 and fig. 14 to 17, according to an alternative example of the present invention, the inner diameter of the air tube adapter 23 is smaller than the inner diameter of the first exhaust tube 21, so that more breakage of the foam can be ensured when the foam enters the air tube adapter 23 from the first exhaust tube 21, and at the same time, the inner diameter of the air tube adapter 23 is smaller than the second exhaust tube 22, so that part of the foam continuing to enter the second exhaust tube 22 can be gradually broken in the second exhaust tube 22, and the foam is prevented from flowing out of the body through the second exhaust tube 22. Of course, the specific inner diameters of the first exhaust pipe 21 and the second exhaust pipe 22 may be adjusted according to actual design requirements, as long as both are smaller than the air pipe adapter 23.

According to still another alternative example of the present invention, the exhaust end 24 of the second exhaust pipe 22 is lower than the junction of the overflow pipe 10 and the first exhaust pipe 21 in the up-down direction, so that the flow path can be increased, the foam is ensured to be gradually broken in the flow path, and the foam is prevented from flowing out of the washing machine through the second exhaust pipe 22 to affect the use.

As shown in fig. 18, 19 and 20, in another embodiment of the present invention, the exhaust assembly 20 includes a first exhaust pipe 21 and a second exhaust pipe (not shown), one end of the first exhaust pipe 21 is connected to the overflow pipe 10 and extends upward in a substantially vertical direction (up-down direction as shown in fig. 7), one end of the second exhaust pipe is connected to the other end of the first exhaust pipe 21, the other end of the second exhaust pipe is opened to form an exhaust end, and the second exhaust pipe is constructed in a bent structure, for example, the second exhaust pipe may be formed in an arc shape or a ring shape extending in a circumferential direction, so that a circulation path may be extended, gradual breakage of foam in the circulation path may be ensured, and outflow of foam out of the washing machine may be prevented from affecting use.

In some examples, to facilitate manufacturing and assembly, to improve the tightness between the first exhaust pipe 21 and the second exhaust pipe, the first exhaust pipe 21 and the second exhaust pipe may be integrally formed therebetween.

As shown in fig. 7, 9 and 10, in one embodiment of the present invention, the overflow pipe 10 is mainly composed of a first overflow pipe 11, a second overflow pipe 12 and a three-way pipe 30, the three-way pipe 30 includes a first port, a second port and a third port, the upper end of the first overflow pipe 11 is connected to the rear tub 400 of the washing machine, the lower end of the first overflow pipe 11 is connected to the first port, the upper end of the second overflow pipe 12 is connected to the second port, the lower end of the second overflow pipe 12 is in communication with the outside, and simultaneously, the air discharge assembly 20 is in communication with the overflow pipe 10 through the third port, thus facilitating the assembly connection of the overflow air discharge assembly 100 and simplifying the manufacturing process.

In one example of the present invention, for ease of manufacture and assembly, the inner diameters of the first and

second overflow pipes

11, 12 are equal, and the inner diameters of the first and

second exhaust pipes

21, 22 are equal, so that interchangeability between the overflow pipes 10 and between the exhaust pipes can be enhanced at the time of assembly.

According to an example of the present invention, in order to prevent excessive foam in the rear tub 400 from being discharged from the overflow pipe 10 and thus from the outlet end of the exhaust pipe through the flow path of the exhaust assembly 20, the inner diameter D1 of the overflow pipe 10 (including the first overflow pipe 11 and the second overflow pipe 12) is set to be larger than the inner diameter D2 of the exhaust pipe (including the first exhaust pipe 21 and the second exhaust pipe 22), whereby the capacity in the flow path of the overflow pipe 10 can be increased, thereby reducing foam entering the exhaust pipe. Of course, those skilled in the art can also extend the length of the exhaust pipe only according to actual design requirements, or set the inner diameter D1 of the overflow pipe 10 to be greater than or equal to the inner diameter D2 of the exhaust pipe, and the above examples can achieve the purpose of avoiding the foam flowing out of the washing machine from the exhaust end 24 of the exhaust assembly 20.
