[0049] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation modes described in the following exemplary embodiments do not represent all the implementation modes consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0050] In the present disclosure, unless otherwise stated, the orientation terms "first direction, second direction, and third direction" refer to three intersecting directions. Specifically, the first direction, the second direction, and the third direction can be perpendicular to each other pairwise, and specifically, reference can be made to Figure 5 as shown; the orientation terms such as "up, down, left, right, front, and back" refer to up, down, left, right, front, and back defined in the normal use state of the washing machine; specifically, reference can be made to Figure 11 as shown; in addition, the above-mentioned first direction can be the up-down direction, the second direction can be the left-right direction, and the third direction can be the front-back direction. The terms such as "first, second" are only used to distinguish one element from another element, and do not have sequentiality and importance.

[0051] Refer to Figures 1 to 12 as shown, the present disclosure provides a washing machine, which includes an outer frame 1, a first cylinder 3, a second cylinder 2, an exhaust structure 1000, and a drying structure 700; an accommodation space 2000 is provided inside the outer frame 1, and the first cylinder 3, the second cylinder 2, the exhaust structure 1000, and the drying structure 700 are all arranged in the accommodation space 2000.

[0052] The axes of the first cylinder 3 and the second cylinder 2 both extend along the front-back direction, and the first cylinder 3 is located above the second cylinder 2. The drying structure 700 and the exhaust structure 1000 are respectively arranged on the outer side walls of the first cylinder 3 opposite to each other in the left-right direction.

[0053] Among them, the first cylinder body 3 is formed with an exhaust port and a drying port. The exhaust structure 1000 is communicated with the exhaust port to discharge the water in the first cylinder body 3, and the drying structure 700 is communicated with the drying port and can convey hot air into the first cylinder body 3.

[0054] In the above technical solution, first, the outer frame 1 can effectively protect the first cylinder body 3, the second cylinder body 2, the exhaust structure 1000 and the drying structure 700; second, the drying structure 700 and the exhaust structure 1000 are respectively arranged on the outer side walls of the first cylinder body 3 facing away from each other in the left-right direction, and respectively drain and dry the first cylinder body 3. The first cylinder body 3 can work independently of the second cylinder body 2. After the clothes in the first cylinder body 3 are washed, there is no need to take them out and put them into another drying cylinder for drying. The drying structure 700 can be used to dry the clothes in the first cylinder body 3, improving the drying efficiency.

[0055] Optionally, the diameter of the above-mentioned first cylinder body 3 can be smaller than that of the second cylinder body 2, and the first cylinder body 3 is obliquely placed above the second cylinder body 2 at a corner of the top of the accommodation space 2000. In addition, for the second cylinder body 2, a drying structural member can also be provided separately, that is, the second cylinder body 2 can also perform washing and drying. The present disclosure does not limit this.

[0056] Optionally, referring to Figures 1 to 4 As shown, the above-mentioned drying structure 700 includes a blower 7001, a drying duct 7002 and a heating element. The drying duct 7002 is arranged on the outer side wall of the first cylinder body 3 extending in the front-rear direction, and the blower 7001 is arranged on the outer side wall of the first cylinder body 3. The first end of the drying duct 7002 is communicated with the blower 7001, the second end of the drying duct 7002 is communicated with the drying port, and the heating element is arranged in the drying duct 7002.

[0057] In this embodiment, the blower 7001 has a motor and blades. The motor drives the blades to rotate, thereby generating an air flow. The air flow enters the drying duct 7002 and is heated by the heating element into dry hot air. The heated dry hot air enters the first cylinder body 3, thereby drying the clothes in the first cylinder body 3.

[0058] Optionally, referring to Figures 1 to 6 As shown, the exhaust structure 1000 includes an exhaust pipe 200 and a drainage and ventilation box 100. A ventilation cavity 20 is arranged inside the drainage and ventilation box 100.

[0059] In this embodiment, after the dry and hot air entering the first cylinder body 3 exchanges heat with the wet and cold clothes, the humid and hot air enters the ventilation cavity 20 in the drainage and ventilation box 100 through the exhaust pipe 200, and then is discharged through the external exhaust port 101. However, the present disclosure does not limit the specific structure of the exhaust structure 1000, and the exhaust structure 1000 can be configured as any appropriate structure. In addition, the drainage and ventilation box 100 is disposed at intervals in the front-rear direction at the rear part of the first cylinder body 3, which can effectively utilize the rear space of the first cylinder body 3, improve the utilization rate of the space, and achieve a compact layout.

[0060] In other embodiments, referring to Figure 3 and Figure 4 as shown, the first cylinder body 3 may include a door seal 31 and a cylinder body main body 32. The axis of the cylinder body main body 32 extends in the front-rear direction, and an open port 320 is formed at the front end of the cylinder body main body 32. The door seal 31 is connected to the front end of the cylinder body main body 32 and exposes the open port 320; the drying structure 700 and the exhaust structure 1000 are respectively disposed on the outer side walls of the cylinder body main body 32 facing away from each other in the left-right direction; wherein, the door seal 31 forms an air inlet passage 310 extending in the left-right direction and penetrating through. The first end of the air inlet passage 310 is configured as a drying port and communicates with the inside of the cylinder body main body 32, and the second end of the air inlet passage 310 communicates with the second end of the drying channel 7002.

[0061] In this embodiment, by providing the air inlet passage 310 in the door seal 31, it is convenient to communicate with the drying channel 7002 of the drying structure 700 to realize air guiding, so that the hot air can enter the first cylinder body 3, which can shorten the setting length of the drying channel 7002. In addition, by making the air inlet passage 310 extend in the left-right direction, the size of the air inlet passage 310 in the up-down direction can be increased as much as possible, without being limited by the connection between the drying channel 7002 of the drying structure 700 and the door seal 31, and the air volume entering the first cylinder body 3 can be increased. In addition, the drying channel 7002 can be integrally formed with the door seal 31, which is convenient for manufacturing and processing.

[0062] Optionally, referring to Figures 1 to 3 as shown, an exhaust port is formed on one side of the side wall of the first cylinder body 3 in the left-right direction. The exhaust pipe 200 is integrally disposed on the outer side wall of the first cylinder body 3 and communicates with the exhaust port. The exhaust port is disposed at the rear side edge of the side wall of the first cylinder body 3. The exhaust pipe 200 protrudes in the left-right direction on the outer side wall of the first cylinder body 3 and protrudes backward beyond the rear cylinder wall of the first cylinder body 3; wherein, the lower end of the drainage and ventilation box 100 protrudes downward beyond the lower end of the first cylinder body 3, and the upper end of the drainage and ventilation box 100 is located below the upper end of the first cylinder body 3.

[0063] In this embodiment, first, by arranging the exhaust port at the rear edge of the side wall of the first cylinder body 3 and making the exhaust pipe 200 protrude backward from the rear cylinder wall of the first cylinder body 3, it is convenient to connect with the drainage and ventilation box 100 arranged at the rear of the first cylinder body 3, effectively shortening the designed length of the exhaust pipe 200. However, the present disclosure does not limit the specific setting position of the exhaust port. Secondly, by integrally arranging the exhaust pipe 200 on the outer side wall of the first cylinder body 3 and communicating it with the exhaust port, there is no need to install and disassemble the exhaust pipe 200, with a high degree of integration, and it can also effectively ensure the structural strength of the exhaust pipe 200. In addition, the lower end of the drainage and ventilation box 100 protrudes downward from the lower end of the first cylinder body 3, and the upper end of the drainage and ventilation box 100 is located below the upper end of the first cylinder body 3, effectively utilizing the lower space without occupying too much upper space, which is beneficial to the layout and installation of other structural parts.

[0064] Referring to Figure 11 and Figure 12 As shown, the outer frame 1 may include a first frame side plate 11, a second frame side plate 12, and a frame rear plate 13. The first frame side plate 11 and the second frame side plate 12 are arranged opposite to and spaced apart from each other in the left-right direction, and the frame rear plate 13 is connected between the first frame side plate 11 and the second frame side plate 12 to enclose an accommodation space 2000. The axis of the second cylinder body 2 is arranged at the middle position in the left-right direction between the first frame side plate 11 and the second frame side plate 12; the axis of the first cylinder body 3 is spaced apart from the axis of the second cylinder body 2 in the left-right direction; the first cylinder body 3 is arranged adjacent to the first frame side plate 11 in the left-right direction, the exhaust structure 1000 is located between the first cylinder body 3 and the first frame side plate 11, and the drying structure 700 is arranged on the side of the first cylinder body 3 away from the first frame side plate 11. That is, the drying structure 700 is arranged closer to the middle of the accommodation space 2000 in the left-right direction relative to the exhaust structure 1000. The structural layout is reasonable and can effectively utilize the space at each position of the accommodation space 2000. However, the present disclosure does not limit the specific layout position.

[0065] Referring to Figure 3 As shown, the exhaust pipe 200 includes an exhaust pipe body 2001 and a front end plate 2002. The exhaust pipe body 2001 is arranged to penetrate in the front-rear direction, and the exhaust pipe body 2001 is connected to the outer side wall of the first cylinder body 3. The front end plate 2002 connects the outer side wall of the first cylinder body 3 and the front end of the exhaust pipe body 2001 to block the front end of the exhaust pipe body 2001. A ventilation notch communicating with the exhaust port is formed on the side pipe wall of the exhaust pipe body 2001 in the left-right direction, and the rear end of the exhaust pipe body 2001 is communicated with the air inlet 102. The structure of the exhaust pipe 200 is simple and can be integrally formed on the first cylinder body 3. However, the present disclosure does not limit the specific structure of the exhaust pipe 200.

[0066] In another embodiment, referring to Figure 3 As shown, a guiding inclined surface 2003 is formed on the front end plate 2002. The guiding inclined surface 2003 is arranged at an angle with the outer side wall of the first cylinder 3, and in the direction away from the first cylinder 3, the guiding inclined surface 2003 extends backward. By providing the guiding inclined surface 2003, it is convenient to guide the gas discharged from the first cylinder 3 to be discharged backward.

[0067] Referring to Figure 1 and Figure 2 As shown, the exhaust structure 1000 may further include a connecting pipe 400. The connecting pipe 400 extends in the front-rear direction. The front end of the connecting pipe 400 is detachably communicated with the rear end of the exhaust pipe 200, and the rear end of the connecting pipe 400 is detachably communicated with the air inlet 102.

By setting the connecting pipe 400 as a rubber pipe, the convenience of connection is improved. For example, the two ends of the rubber pipe can be slightly larger than the sizes of the exhaust pipe 200 and the intake pipe 70. In order to ensure the sealing performance, an interference fit can be used for connection.

[0069] In one embodiment, referring to Figures 5 to 10 As shown, the drain and ventilation box 100 includes a first housing 105, a second housing 106, and a third housing 108; the ventilation cavity 20 includes a first exhaust passage 201 and a second exhaust passage 202 that communicate with each other.

[0070] In this embodiment, the gas first enters the second exhaust passage 202 through the air inlet 102, and then is discharged to the first exhaust passage 201 provided in the first housing 105, and then is discharged through the external exhaust port 101 to the ventilation cavity 20, realizing the exhaust of the first cylinder 3. The third housing 108 and the second housing 106 can be arranged on both sides of the first housing 105 in any suitable manner. For example, the third housing 108 and the second housing 106 can be detachably connected to both sides of the first housing 105 by means of fasteners such as bolts, and the present disclosure does not limit this.

[0071] Referring Figure 5 and Figure 10 As shown, the drain ventilation box 100 may further include an intake pipe 70, an external exhaust pipe 80, a defoaming pipe body (not shown), and a defoaming pipe head 90. The intake pipe 70 is connected to the outer wall of the third housing 108 and communicates with the air inlet 102, and the intake pipe 70 communicates with the exhaust pipe 200; the external exhaust pipe 80 is connected to the outer wall of the second housing 106 and communicates with the external exhaust port 101; the first cylinder 3 is formed with a first defoaming hole, the third housing 108 is formed with a second defoaming hole, the second defoaming hole communicates with the second exhaust passage 202, and the defoaming pipe head is connected to the outer wall of the third housing 108 and communicates with the second defoaming hole; one end of the defoaming pipe body communicates with the first defoaming hole, and the other end of the defoaming pipe body communicates with the defoaming pipe head 90.

[0072] In this embodiment, by providing the intake pipe 70, it is convenient to communicate with the exhaust pipe 200. The intake pipe 70 can be integrally formed on the third housing 108 or detachably connected to the third housing 108. By providing the external exhaust pipe 80, it is convenient to discharge the gas from the ventilation cavity 20. The external exhaust pipe 80 can be integrally formed on the second housing 106 or detachably arranged on the second housing 106, and the present disclosure does not limit this. In addition, by providing the defoaming pipe body and connecting the two ends to the first defoaming hole and the second defoaming hole respectively, external air can enter the first cylinder 3, thereby breaking the foam in the first cylinder 3 and preventing excessive foam from affecting the normal operation of the washing machine.

[0073] Referring Figures 5 to 10 As shown, the drain ventilation box 100 may include a housing 10. The housing 10 is internally provided with the above-mentioned ventilation cavity 20 and drain cavity 30 that are independent of each other and separated. A plurality of interconnected drain channels 301 are provided in the drain cavity 30. The housing 10 is provided with an external drain port 103 and a plurality of water inlets 104. The water inlets 104 are arranged in one-to-one correspondence with the drain channels 301, and the water inlets 104 communicate with the upstream ends of the corresponding drain channels 301, and the external drain port 103 communicates with the downstream ends of the plurality of drain channels 301.

[0074] In the above technical solution, by providing a ventilation cavity 20 and a drainage cavity 30 in the housing 10, the gas entering from the air inlet 102 can enter the ventilation cavity 20 and then be discharged through the external exhaust port 101. Water enters into a plurality of drainage channels 301 through a plurality of water inlets 104. Since the plurality of drainage channels 301 communicate with each other in the drainage cavity 30, the water can be discharged from the drainage cavity 30 through the external drainage port 103. In addition, the ventilation cavity 20 and the drainage cavity 30 are independent and separated from each other. That is to say, the drainage and ventilation box 100 of the present disclosure integrates the ventilation cavity 20 and the drainage cavity 30 in one housing 10, which can not only drain water but also ventilate, with a compact structural design and high integration, effectively reducing the number of parts and costs.

[0075] In the application scenario of a washing machine, the water in the washing tub of the washing machine can be drained through the drainage cavity 30, and the ventilation of the washing tub can be carried out through the ventilation cavity 20.

[0076] The washing machine may further include the above-mentioned first cylinder 3, second cylinder 2, first drain pipe, and second drain pipe. One end of the first drain pipe communicates with the drain port of the first cylinder 3, and the other end communicates with the second water inlet 1042; one end of the second drain pipe communicates with the drain port of the second cylinder 2, and the other end communicates with the first water inlet 1041. Wherein, the first direction A can be configured as the up-down direction, the second direction B can be configured as the left-right direction, and the third direction C can be configured as the front-back direction. That is to say, the drainage of both the first cylinder 3 and the second cylinder 2 is discharged into the drainage cavity 30, realizing the drainage of the first cylinder 3 and the second cylinder 2, as well as the exhaust of the first cylinder 3, which is beneficial to the simplification of the structure and the non-interference between drainage and exhaust.

At least a portion of the channel segments extends along the first direction A, and the plurality of channel segments are spaced apart from each other in the second direction B. Thus, the first drainage channel 3011 can be arranged in a meandering channel shape to meet the drainage requirements. However, the present disclosure does not limit the specific shape of the first drainage channel 3011. Additionally, the present disclosure does not limit the number of the drainage channels 301 and the water inlet 104.

[0082] In this embodiment, the first housing 105 and the second housing 106 are mated with each other to define a drainage cavity 30, which facilitates installation and disassembly. However, the present disclosure does not limit the specific structure of the housing 10.

[0083] Among them, the partition plate 107 can be provided only on the first housing 105. For example, one side of the partition plate 107 along the third direction C is connected to the inner wall of the first housing 105, and the other side along the third direction C abuts against the inner wall of the second housing 106. Alternatively, the partition plate 107 can be provided only on the second housing 106. For example, one side of the partition plate 107 along the third direction C is connected to the inner wall of the second housing 106, and the other side along the third direction C abuts against the inner wall of the first housing 105.

The first partition plate 1071 and the second partition plate 1072 can be configured as two independent structures and formed by a connection method. Alternatively, the first partition plate 1071 and the second partition plate 1072 can also be integrally formed. Alternatively, the first partition plate 1071 and the second partition plate 1072 can be integrally formed with the first housing 105, or the first partition plate 1071 and the second partition plate 1072 can also be integrally formed with the second housing 106, and the present disclosure does not limit this.

By providing the channel gap 300, it is used to conduct the first channel section 3013 and the second channel section 3014, which facilitates the realization of the connection relationship between the channel sections.

[0086] In one embodiment, with reference to Figure 6 and Figure 9 as shown, the second partition plate 1072 includes a straight plate segment 1073 and an arc plate segment 1074 that are connected to each other. One end of the straight plate segment 1073 is angularly connected to the first partition plate 1071. The other end of the straight plate segment 1073 is connected to the arc plate segment 1074. The arc plate segment 1074 is bent toward the first partition plate 1071 and is spaced from the first partition plate 1071.

[0087] Wherein, the outer walls of the straight plate segment 1073 and the arc plate segment 1074 are spaced from the inner wall of the drainage cavity 30 and define the second channel segment 3014 as described above. The outer walls of the straight plate segment 1073 and the arc plate segment 1074 and the first partition plate 1071 define the second drainage channel 3012 as described above. In addition, the arc plate segment 1074 is bent toward the first partition plate 1071 and is spaced from the first partition plate 1071, so that the second channel segment 3014 communicates with the second drainage channel 3012. However, the present disclosure does not limit the specific shape of the second partition plate 1072.

[0088] With reference to Figure 6 and Figure 7 as shown, the first housing 105 includes a first bottom plate 1051 and a first side enclosure 1052. The first side enclosure 1052 is disposed around and connected to the outer periphery of the first bottom plate 1051. The second housing 106 is connected to the first side enclosure 1052 in an opposing manner. Among them, the first water inlet 1041 is disposed on the first side enclosure 1052, the second water inlet 1042 is disposed on the first bottom plate 1051 and is located between the first partition plate 1071 and the second partition plate 1072, and the external drainage port 103 is disposed on the second housing 106. The first housing 105 can be configured in any suitable shape and structure, and the present disclosure does not limit this. In addition, the present disclosure also does not limit the specific installation positions of the first water inlet 1041, the second water inlet 1042, and the external drainage port 103.

[0089] In addition, with reference to Figures 5 to 10 as shown, the drainage and ventilation box 100 may further include a first water inlet pipe 40, a second water inlet pipe 50, and an external drainage pipe 60. The first water inlet pipe 40 is disposed on the outer wall of the first side enclosure 1052 and extends along the first direction A, and the first water inlet pipe 40 communicates with the first water inlet 1041. The second water inlet pipe 50 is disposed on the outer wall of the first bottom plate 1051 and extends along the third direction C, and the second water inlet pipe 50 communicates with the second water inlet 1042. The external drainage pipe 60 is disposed on the outer wall of the second housing 106 and extends along the third direction C, and the external drainage pipe 60 communicates with the external drainage port 103. By providing the first water inlet pipe 40, the second water inlet pipe 50, and the external drainage pipe 60, it is convenient to communicate with external pipelines.

[0090] In other embodiments, the washing machine may further include a drain pump and a drain valve; wherein, the first cylinder 3 and the drain and ventilation box 100 are both disposed above the second cylinder 2; the small cylinder drain port is located above the second water inlet 1042, and the drain valve is disposed on the small cylinder drain pipe; the large cylinder drain port is disposed below the first water inlet 1041, and the drain pump is disposed on the large cylinder drain pipe.

[0091] In this embodiment, since the large cylinder drain port is disposed below the first water inlet 1041, it is convenient to realize the upward conveyance of the drainage by setting the drain pump. The small cylinder drain port is located above the second water inlet 1042, so that the water can be conveyed to the drain cavity 30 by the action of gravity. By setting the drain valve, it is convenient to control the opening and closing of the drain pipeline.

[0092] Optionally, the second end of the first partition plate 1071 is configured as the upper end of the first partition plate 1071; wherein, the second end of the first partition plate 1071 is located above the air inlet 102, and the second end of the first partition plate 1071 is located above the maximum washing water level and the abnormal alarm water level of the first cylinder 3.

[0093] First, due to the pumping pressure of the drain pump, the drainage of the first cylinder 3 can be prevented from flowing back into the second cylinder 2. When the external drain pipe 60 is blocked, the drainage of the first cylinder 3 is discharged into the second drainage channel 3012. When the second drainage channel 3012 is filled with drainage and flows back into the second channel section 3014, since the second end of the first partition plate 1071 is located above the maximum washing water level and the abnormal alarm water level of the first cylinder 3, when the water in the first cylinder 3 reaches the maximum washing water level and the abnormal alarm water level, the first cylinder 3 will not continue to intake water, that is, the drainage will not flow back into the first channel section 3013 through the second channel section 3014, that is, it will not flow back into the second cylinder 2.
