The second spraying assembly is higher than the first spraying assembly, and the second spraying assembly comprises a second article shelf which is detachably mounted on the water supply shaft. The second article shelf is used for placing to-be-cleaned articles. The second article shelf comprises a first sub-article shelf and a second sub-article shelf which can be selected. The first sub-article shelf is provided with an avoiding gap which is used for avoiding the to-be-cleaned articles on the first article shelf.

[0008] Through the above technical solution, the spraying device provided by the application can place to-be-cleaned articles by using the second article shelf on the basis of the first article shelf, increase the position for placing to-be-cleaned articles, increase the number of to-be-cleaned articles placed in the cleaning cavity of the cleaning machine, and then fully utilize the space of the cleaning cavity, which is conducive to improving the cleaning efficiency.

[0009] In addition, the second shelf includes a first sub-shelf and a second sub-shelf, the second sub-shelf is provided with an avoiding gap, the avoiding gap is used for avoiding the to-be-cleaned articles on the first shelf, that is, the user can select to use the first sub-shelf or the second sub-shelf according to the height of the to-be-cleaned articles on the first shelf. When the height of the to-be-cleaned articles on the first shelf is relatively high, the first sub-shelf can be selected to use, so that the to-be-cleaned articles on the first shelf can be avoided by using the avoiding gap, and the customer experience can be improved.

[0010] Therefore, the spraying device provided by the application can improve the use experience.

[0011] In some embodiments, the second spraying assembly includes a second spraying arm detachably mounted on the water supply shaft, the second spraying arm includes a first sub-spraying arm and a second sub-spraying arm, the first sub-spraying arm is used in cooperation with the first sub-shelf, and the first sub-spraying arm is used for spraying the cleaning liquid towards the first sub-shelf, the second sub-spraying arm is used in cooperation with the second sub-shelf, and the second sub-spraying arm is used for spraying the cleaning liquid towards the second sub-shelf.

[0012] In this way, the first sub-spraying arm and the first sub-shelf can be selected at the same time, the second sub-spraying arm and the second sub-shelf can be selected at the same time, and the first sub-spraying arm and the second sub-spraying arm can clean the to-be-cleaned articles on the second shelf.

[0013] In some embodiments, the length of the first sub-spraying arm is less than the length of the second sub-spraying arm; and / or, the first sub-spraying arm does not exceed the edge of the avoiding gap.

[0014] In this way, the first sub-spraying arm can avoid the to-be-cleaned articles on the first shelf together with the first sub-shelf.

[0015] In some embodiments, one of the water supply shaft and the second shelf is provided with a socket, and the other is provided with a plug rod, the plug rod is inserted into the socket.

[0016] And / or, the spraying device includes a limiting structure, the limiting structure is used for limiting the relative rotation of the water supply shaft and the second shelf.

[0021] And / or, the mass of the second shelf is smaller than the mass of the first shelf.

[0022] In this way, compared with the first shelf, the second shelf occupies less space, facilitating the disassembly and assembly of the second shelf and other components adjacent to the second shelf. In addition, the mass of the second shelf is smaller than the mass of the first shelf, which can reduce the pressure exerted by the second shelf on the water supply shaft, thereby facilitating the reduction of the load of the water supply shaft.

[0023] In some embodiments, the avoidance gap is arranged on the outer circumferential side of the first sub-shelf. In this way, the first sub-shelf can increase the number of avoidance gaps, thereby increasing the number of washable articles that can be avoided, without changing the size of the avoidance gap.

[0024] In some embodiments, the avoidance gap includes a plurality of avoidance gaps, and the plurality of avoidance gaps are arranged equidistantly on the circumference of the avoidance gap.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0076] Please refer to the following: Figure 1 and Figure 2 This application provides a cleaning machine 100, which includes a body 20 and a cover 10. The cover 10 is connected to the body 20 and can be enclosed to form a cleaning chamber 110.

[0077] The cleaning machine 100 provided in this application embodiment also includes a spray device 30, which can be disposed in the cleaning chamber 110 and can clean the items to be cleaned in the cleaning chamber 110.

[0078] When the spray device 30 cleans the items to be cleaned in the cleaning chamber 110, the cleaning machine 100 uses the spray device 30 to spray cleaning liquid onto the items to be cleaned in the internal cleaning chamber 110. Some container-type items to be cleaned need to be placed on a shelf. These container-type items can be cups, bowls, baby bottles, etc. It is understood that the items to be cleaned may also include lids and other parts of the container-type items.

[0079] The cleaning machine 100 provided in this application embodiment also includes a pump assembly, which includes a washing pump and a drain pump. The washing pump is used to provide cleaning fluid to the spray device 30, and the drain pump is used to remove wastewater from the cleaning chamber 110.

[0080] Optionally, the washing pump and the sewage pump are respectively located at the bottom of the body 20.

[0081] The inventors discovered that some spray devices 30 have limited space for placing items to be cleaned, and the number of items to be cleaned in the cleaning chamber 110 is limited, resulting in the space at the top of the cleaning chamber 110 not being used effectively and the cleaning efficiency being low.

[0082] In related technologies, the spray device 30 is equipped with multi-layer shelves to increase the number of items to be cleaned. However, some items to be cleaned are quite tall and may interfere with the upper shelves, affecting the user experience.

[0083] To resolve the above technical issues, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This application provides a spray device 30, which includes a water supply shaft 37. The water supply shaft 37 is provided with a water supply port 372 for connecting to a water source, and the water supply shaft 37 has a cavity 4741 communicating with the water supply port 372.

[0084] The water supply port 372 is used to connect to the outlet of the washing pump, so that the washing pump can deliver cleaning fluid to the water supply shaft 37.

[0085] Please see Figure 2 The spray device 30 provided in this embodiment further includes a first spray assembly, which includes a first spray arm 33 and a first shelf 31 mounted on a water supply shaft 37. The first shelf 31 is used to place items to be cleaned, and the first spray arm 33 is used to spray cleaning fluid toward the first shelf 31. The first spray arm 33 may be provided with a first spray channel communicating with a cavity 4741 of the water supply shaft 37 and a first spray hole communicating with the first spray channel. The opening of the first spray hole faces the first shelf 31. Therefore, the water supply shaft 37 can supply cleaning fluid to the first spray arm 33, so that the first spray arm 33 can spray cleaning fluid toward the first shelf 31.

[0086] The spray device 30 provided in this application embodiment further includes a second spray assembly, which includes a second shelf 32 detachably installed on the water supply shaft 37. The second shelf 32 is used to place items to be cleaned.

[0087] The second shelf 32 is detachably installed on the water supply shaft 37. The second shelf 32 can be replaced for different types and sizes of items to be cleaned, making it highly adaptable.

[0088] Optionally, the first spray assembly and the second spray assembly are aligned along the axial direction of the water supply shaft 37 (e.g., Figure 3 The Z-axis spacing is set. For example, the axial direction of the water supply shaft 37 is aligned with the vertical direction. The second spray assembly is higher than the first spray assembly.

[0089] It is understood that, based on the first shelf 31, the spray device 30 provided in this application embodiment can also use the second shelf 32 to place items to be cleaned, thereby increasing the number of items to be cleaned that can be placed in the cleaning chamber 110 of the cleaning machine 100, and thus making full use of the space of the cleaning chamber 110, which is beneficial to improving cleaning efficiency.

[0090] Therefore, the spray device 30 provided in this application embodiment can improve cleaning efficiency.

[0091] Optionally, the first spray arm 33 is located on the side of the first shelf 31 near the water supply port 372. That is, the first spray arm 33 is located below the first shelf 31.

[0092] Understandably, the position of the first spray arm 33 relative to the first shelf 31 can be set according to the type and shape of the items to be cleaned, making it highly adaptable.

[0093] Optionally, please refer to the following as well. Figure 2 , Figure 3 and Figure 5 The second shelf 32 includes a first sub-shelf 321 and a second sub-shelf 322, which can be selected. The first sub-shelf 321 has a clearance notch 3213 for clearing items to be cleaned on the first shelf 31. That is, the user of the washing machine 100 can choose to use either the first sub-shelf 321 or the second sub-shelf 322 based on the height of the items to be cleaned on the first shelf 31. When the items to be cleaned on the first shelf 31 are relatively high, the first sub-shelf 321 can be used, utilizing the clearance notch 3213 to clear the items, thus improving the user experience.

[0094] Therefore, the spray device 30 provided in this application embodiment can improve the user experience.

[0095] In some embodiments, the spraying device 30 provided in this application further includes a second spraying arm 34 detachably mounted on the water supply shaft 37, the second spraying arm 34 being used to spray cleaning liquid toward the second shelf 32.

[0096] The second spray arm 34 is detachably installed on the water supply shaft 37. The second spray arm 34 can be replaced for different types and sizes of items to be cleaned, making it highly adaptable.

[0097] In addition, the second spray arm 34 may be provided with a second spray channel communicating with the cavity 4741 of the water supply shaft 37 and a second spray hole communicating with the second spray channel. The opening of the spray hole faces the first shelf 31. Therefore, the water supply shaft 37 of the first shelf 31 can provide cleaning fluid to the first spray arm 33 so that the second spray arm 34 can spray cleaning fluid toward the second shelf 32.

[0098] Optionally, the second spray arm 34 is located on the side of the second shelf 32 near the water supply port 372. That is, the second spray arm 34 is located below the second shelf 32.

[0099] Understandably, the position of the second spray arm 34 relative to the second shelf 32 can be set according to the type and shape of the items to be cleaned, making it highly adaptable.

[0100] Optionally, the second spray arm 34 includes a first sub-spray arm 341 and a second sub-spray arm 342, which are optional. The first sub-spray arm 341 is used in conjunction with the first sub-shelf 321 and is used to spray cleaning fluid toward the first sub-shelf 321. The second sub-spray arm 342 is used in conjunction with the second sub-shelf 322 and is used to spray cleaning fluid toward the second sub-shelf 322.

[0101] In this way, the first sub-spray arm 341 and the first sub-shelf 321 can be used simultaneously, and the second sub-spray arm 342 and the second sub-shelf 322 can be used simultaneously. The first sub-spray arm 341 and the second sub-spray arm 342 can clean the items to be cleaned on the second shelf 32.

[0102] Please refer to the following: Figure 7 and Figure 8 In some embodiments, the first spray arm 33 and the first shelf 31 are spaced apart along the axial direction of the water supply shaft 37. The first spray arm 33 is rotatably connected to the water supply shaft 37, which supplies water to the first spray arm 33. In this way, the first shelf 31 will not interfere with the first spray arm 33, and the first spray arm 33 can be rotatably connected to the water supply shaft 37, thereby allowing the first spray arm 33 to spray cleaning fluid onto different positions of the first shelf 31.

[0103] In addition, the rotation of the first spray arm 33 can increase the cleaning range and uniformity.

[0104] It is understandable that the first spray arm 33 can be provided with a first reverse thrust hole that communicates with the first spray channel, so that the first spray arm 33 can rotate by the reverse torque generated by the water flow discharged from the first reverse thrust hole.

[0105] Please continue reading. Figure 8Optionally, the second spray arm 34 and the second shelf 32 are spaced apart along the axial direction of the water supply shaft 37. The second spray arm 34 is rotatably connected to the water supply shaft 37, which supplies water to the second spray arm 34. In this way, the second shelf 32 will not interfere with the second spray arm 34, and the second spray arm 34 can be rotatably connected to the water supply shaft 37, thereby allowing the second spray arm 34 to spray cleaning fluid onto different positions of the second shelf 32.

[0106] In addition, the rotation of the second spray arm 34 can increase the cleaning range and uniformity.

[0107] It is understandable that the second spray arm 34 can be provided with a second reverse thrust hole that communicates with the second spray channel, so that the second spray arm 34 can rotate by the reverse torque generated by the water flow discharged from the second reverse thrust hole.

[0108] Please continue reading. Figure 8 In some embodiments, along the axial direction of the water supply shaft 37, the first spray assembly and the second spray assembly are located on the same side of the water supply port 372, with the first spray assembly located on the side of the second spray assembly closer to the water supply port 372. Optionally, the water supply port 372 of the water supply shaft 37 is located at the bottom of the water supply shaft 37, and the first spray assembly and the second spray assembly are located above the water supply port 372.

[0109] In this way, the water supply port 372 can bypass the first and second spray components, avoiding interference between the pipe connected to the water supply port 372 and the first and second spray components. In addition, the water supply port 372 and the pipe connected to the water supply port 372 will not occupy the space between the first and second spray components, so that the spray device 30 can prevent the items to be cleaned from being placed in the space between the first and second spray components.

[0110] Please see Figure 9 and Figure 10 In some embodiments, the radial dimension of the second shelf 32 along the water supply axis 37 is smaller than that of the first shelf 31 along the water supply axis 37. Exemplarily, the orthographic projection of the second shelf 32 along the axial direction of the water supply axis 37 lies within the orthographic projection of the first shelf 31 along the axial direction of the water supply axis 37. Thus, the area enclosed by the outer periphery of the orthographic projection of the second shelf 32 along the axial direction of the water supply axis 37 is smaller than the area enclosed by the outer periphery of the orthographic projection of the first shelf 31 along the axial direction of the water supply axis 37. Therefore, compared to the first shelf 31, the second shelf 32 occupies less space, facilitating the assembly and disassembly of the second shelf 32 and other components adjacent to it.

[0111] Optionally, the mass of the second shelf 32 is less than that of the first shelf 31, which can reduce the pressure exerted by the second shelf 32 on the water supply shaft 37 and help reduce the load on the water supply shaft 37.

[0112] Optionally, the length of the first sub-spray arm 341 is shorter than the length of the second sub-spray arm 342. In this way, the first sub-spray arm 341 can avoid the items to be cleaned, avoid interference with the items to be cleaned, and improve the user experience of using the cleaning machine 100.

[0113] Optionally, the first sub-spray arm 341 does not extend beyond the edge of the clearance notch 3213 to avoid items to be cleaned that extend into the clearance notch 3213 on the first shelf 31.

[0114] For example, the first sub-spray arm 341 is located inside the clearance notch 3213. In this way, the first sub-spray arm 341 can work together with the first sub-shelf 321 to avoid the items to be cleaned on the first shelf 31.

[0115] Please return to the reference. Figure 3 , Figure 4 and Figure 9 In some embodiments, the clearance notch 3213 is provided on the outer periphery of the first sub-shelf 321. In this way, while keeping the size of the clearance notch 3213 unchanged, the number of clearance notches 3213 in the first sub-shelf 321 can be increased, thereby increasing the number of items to be washed that can be cleared.

[0116] For example, the avoidance gap 3213 includes a plurality of gaps, and the plurality of avoidance gaps 3213 are equally spaced around the periphery of the avoidance gap 3213.

[0117] Optionally, the outer periphery of the shelf body 3211 is provided with a clearance surface 3214, which is a concave arc surface and defines a clearance notch 3213.

[0118] Among them, the avoidance surface 3214 can increase the size of the avoidance gap 3213, which is beneficial to increase the size of the items to be cleaned that can be avoided, thereby improving the applicability of the cleaning machine 100. Therefore, the cleaning machine 100 has good applicability.

[0119] Please continue reading. Figure 3 , Figure 4 and Figure 9 Optionally, the first sub-shelf 321 includes a shelf body 3211 and a plurality of extensions 3212. The shelf body 3211 is mounted on the water supply shaft 37, and the extensions 3212 are connected to the outer periphery of the shelf body 3211. The plurality of extensions 3212 are spaced apart around the shelf body 3211. Along the circumference of the water supply shaft 37, an avoidance gap 3213 is formed between two adjacent extensions 3212.

[0120] Where the height of the item to be cleaned is greater than the distance between the first shelf 31 and the second shelf 32, the item can pass through the clearance notch 3213 to avoid interference. Therefore, the spray device 30 provided in this embodiment can clean items with greater height and has good applicability.

[0121] For example, along the circumference of the water supply axis 37, the clearance surface 3214 is located between two adjacent extensions 3212 and is connected to the two adjacent extensions 3212 respectively.

[0122] Please return to the reference. Figure 5 , Figure 6 and Figure 10 The area enclosed by the outer periphery of the second sub-shelf 322, projected along the axial direction of the water supply axis 37, is a polygon or a circle. That is, the second shelf 32 has a polygonal or circular outer frame, which is beneficial for placing more items to be washed.

[0123] Please return to the reference. Figure 7 and Figure 8 In some embodiments, one of the water supply shaft 37 and the second shelf 32 is provided with a socket 3201, and the other is provided with a plug 371, which is inserted into the socket 3201. In this way, the second shelf 32 can be detachably connected to the water supply shaft 37.

[0124] Optionally, the spray device 30 includes a limiting structure for limiting the relative rotation of the water supply shaft 37 and the second shelf 32.

[0125] For example, the outer peripheral side of the insertion rod 371 is provided with at least one first plane, and the inner peripheral side of the insertion hole 3201 is provided with at least one second plane. The first plane and the second plane are in contact, and the limiting structure includes the first plane and the second plane.

[0126] In this way, the water supply shaft 37 and the second shelf 32 can be relatively fixed around the circumference of the insertion rod 371, which can prevent the second shelf 32 from rotating, thereby improving stability.

[0127] Optionally, the insertion rod 371 is a square rod, and the insertion hole 3201 is a square hole.

[0128] For example, the insertion rod 371 is disposed on the top of the water supply shaft 37.

[0129] For example, the socket 3201 includes a first insertion hole disposed on the first sub-shelf 321. When the customer selects the first sub-shelf 321, the insertion rod 371 can be inserted into the first insertion hole.

[0130] For example, the socket 3201 includes a second insertion hole provided on the second sub-shelf 322. When the customer selects the second sub-shelf 322, the insertion rod 371 can be inserted into the second insertion hole.

[0131] The inventors also discovered that in related technologies, the washing pump and the sewage pump are connected in parallel along the axial direction, occupying a large amount of space. This may affect the overall layout of the cleaning machine 100, causing difficulties in the design and manufacturing of the entire machine.

[0132] Please see Figure 11 and Figure 12 To solve the above-mentioned technical problems, this application provides a washing and sewage pump 40, which includes a washing pump and a sewage pump. The washing pump includes a washing pump housing 41, and the sewage pump includes a sewage pump housing 42 connected to the washing pump housing 41. The washing pump housing 41 has a first direction (e.g., Figure 12 The first axis 001 extends in the X direction, and the sewage pump housing 42 has a second axis (such as the X direction) extending in the X direction. Figure 12 The second axis 002 extends from the Y direction of the first axis 001 of the washing pump housing 41. The first direction intersects the second direction; that is, the extension direction of the first axis 001 of the washing pump housing 41 intersects the extension direction of the second axis 002 of the sewage pump housing 42. This helps to reduce the axial dimensions of the washing pump housing 41 along both the first axis 001 and the second axis 002, thereby reducing the space occupied.

[0133] Therefore, the washing and sewage pump 40 provided in this application embodiment is beneficial to reducing the space occupied and the layout of the washing machine 100, thereby reducing the difficulty of the overall machine design and manufacturing.

[0134] Please see Figure 13 Optionally, the first direction is perpendicular to the second direction, that is, the extension direction of the first axis 001 of the washing pump housing 41 is perpendicular to the extension direction of the second axis 002 of the sewage pump housing 42. This is beneficial to further reduce the overall size of the washing and sewage pump 40, thereby further reducing the space occupied and facilitating processing and manufacturing.

[0135] Please continue reading. Figure 12 and Figure 13 In some embodiments, the washing and sewage pump 40 provided in this application also includes a water inlet shell 43, which is connected to the washing pump shell 41 and the sewage pump shell 42 respectively. The water inlet shell 43 has a water inlet cavity 4301 and a water inlet hole 4302 communicating with the water inlet cavity 4301.

[0136] Optionally, the washing pump housing 41 has a water outlet chamber 4101 and a water outlet hole 4102 communicating with the water outlet chamber 4101, the sewage pump housing 42 has a sewage discharge chamber 4201 and a sewage outlet hole 4202 communicating with the sewage discharge chamber 4201, and the water inlet chamber 4301 is communicating with the water outlet chamber 4101 and the sewage discharge chamber 4201 respectively.

[0137] In this way, the washing and sewage pump 40 provided in this application embodiment can be connected to the water outlet chamber 4101 of the washing pump housing 41 and the sewage discharge chamber 4201 of the sewage pump housing 42 through the water inlet chamber 4301 of the water inlet housing 43, which can reduce the number of connecting channels and simplify the structure.

[0138] Optionally, the drain hole 4202 is oriented in the same direction as the first direction.

[0139] Optionally, the drain hole 4202 is oriented in the same direction as the second direction.

[0140] Optionally, the drain hole 4202 is oriented in the same direction as the water inlet hole 4302.

[0141] Understandably, the orientation of the drain hole 4202 can be configured in various ways to adapt to the structural layout of the cleaning machine 100, making it highly adaptable.

[0142] Optionally, the water outlet 4102 and the water inlet 4302 face the same direction. This facilitates the circulation of washing water in and out of the washing and sewage pump 40 and makes the pipeline layout easier.

[0143] In some embodiments, the water inlet cavity 4301 has a third direction (e.g., Figure 12 The third axis 003 of the inlet chamber 4301 is connected in the Z direction and is perpendicular to the first direction and / or the second direction. That is, the extension direction of the third axis 003 of the inlet chamber 4301 is perpendicular to the extension direction of the first axis 001 of the washing pump housing 41 and / or the extension direction of the second axis 002 of the sewage pump housing 42.

[0144] In this way, the water inlet chamber 4301 can reduce its axial dimensions along the first axis 001 and the second axis 002, which helps to reduce the space occupied along the first axis 001 and the second axis 002, thereby helping to reduce the space occupied by the washing and sewage pump 40.

[0145] For example, the third direction is perpendicular to the first and second directions. It can be understood that the first, second, and third directions can be three directions in a spatial coordinate system.

[0146] Optionally, the water inlet hole 4302 of the water inlet chamber 4301 is connected to the cleaning chamber 110 inside the machine body 20, and the washing water in the cleaning chamber 110 can enter the water inlet chamber 4301 through the water inlet hole 4302. During the washing process, the washing water in the cleaning chamber 110 enters the water outlet chamber 4101 from the water inlet chamber 4301, and then enters the cleaning chamber 110 through the water outlet hole 4102. The washing water in the cleaning chamber 110 circulates between the cleaning chamber 110, the water inlet chamber 4301, and the water outlet chamber 4101. During the draining process after washing, the washing water in the cleaning chamber 110 enters the drain chamber 4201 from the water inlet chamber 4301, and then is discharged to the outside through the drain hole 4202.

[0147] Optionally, the body 20 includes a circulation inlet 111 and a circulation outlet 1121 that are connected to the cleaning chamber 110. The circulation inlet 111 is connected to the water outlet 4102 of the water outlet chamber 4101, and the circulation outlet 1121 is connected to the water inlet 4302 of the water inlet chamber 4301.

[0148] Optionally, to facilitate the manufacturing of the washing and sewage pump 40, the inlet housing 43, the washing pump housing 41, and the sewage pump housing 42 are integrally connected.

[0149] The inventors discovered that during the cleaning process of the washing machine 100, impurities removed from the items being cleaned mix with the washing water. During the cleaning process, the washing water in the washing chamber 110 circulates between the washing chamber 110, the inlet chamber 4301, and the outlet chamber 4101. Large impurities in the washing water entering the outlet chamber 4101 of the washing pump housing 41 may cause the washing pump to become clogged. Furthermore, during the sewage discharge process, some impurities in the washing water entering the sewage discharge chamber 4201 of the sewage discharge pump housing 42 may cause the sewage discharge pump to become clogged.

[0150] Please refer to the following: Figure 11 , Figure 14 and Figure 15 The washing and sewage pump 40 provided in this application embodiment also includes a filter element 47, which is used to filter the washing water entering the water outlet chamber 4101 and the sewage discharge chamber 4201.

[0151] The filter element 47 can be installed at the circulation outlet 1121 of the cleaning chamber 110.

[0152] Optionally, at least a portion of the filter element 47 is disposed in the water inlet chamber 4301 through the water inlet hole 4302. The filter element 47 includes a filter channel 4711 and a water inlet 4712 communicating with the filter channel 4711, a first filter screen 4713 and a second filter screen 4714. The first filter screen 4713 includes a plurality of first filter holes 47131 and the second filter screen 4714 includes a plurality of second filter holes 47141.

[0153] The first filter screen 4713 is connected to the water outlet chamber 4101, and the second filter screen 4714 is connected to the sewage discharge chamber 4201. The aperture of the first filter hole 47131 is smaller than the aperture of the second filter hole 47141.

[0154] In this way, the washing and sewage pump 40 provided in this application can use the first filter screen 4713 of the filter element 47 to filter the washing water entering the outlet chamber 4101 of the washing pump, thus avoiding clogging of the washing pump. The washing and sewage pump 40 provided in this application can also use the second filter screen 4714 of the filter element 47 to filter the washing water entering the sewage discharge chamber 4201 of the sewage pump, thus avoiding clogging of the sewage pump.

[0155] In addition, the first filter hole 47131 of the first filter screen 4713 has a smaller aperture, which can prevent impurities from entering the water outlet chamber 4101, while the second filter hole 47141 of the second filter screen 4714 has a larger aperture, which can allow some impurities to be discharged from the drain pump along with the washing water.

[0156] Optionally, the filter element 47 includes a filter tube 471, the cavity of which includes a filter channel 4711. A first filter screen 4713 and a second filter screen 4714 are disposed on the tube wall of the filter tube 471, and a communication port is also disposed on the filter tube 471. This facilitates the fabrication of the first filter screen 4713 and the second filter screen 4714.

[0157] The first filter screen 4713 and the second filter screen 4714 can be integrated on the filter tube 471.

[0158] Optionally, the filter element 47 also includes a mounting component 472, which is connected to the filter tube 471, and the filter element 47 can be mounted at the bottom of the cleaning chamber 110 via the mounting component 472.

[0159] The mounting component 472 has a water collection tank 4721, and the water inlet 4712 is connected to the water collection tank 4721. The water collection tank 4721 can guide the washing water to the filter channel 4711, which helps to improve the filtration efficiency.

[0160] For example, the water inlet 4712 is provided on the bottom wall of the water collection tank 4721.

[0161] It is understood that the filter element 47 provided in this application embodiment can filter the washing water entering the washing pump using the first filter hole 47131 with a relatively small pore size, and can also filter the washing water entering the sewage pump using the second filter hole 47141 with a relatively large pore size, so that some dirt can be discharged with the washing wastewater. That is, the filter element 47 provided in this application embodiment can filter the washing water entering the washing pump and the sewage pump respectively, which can improve the integration.

[0162] In some embodiments, the washing and sewage pump 40 provided in this application also includes a sewage valve (not shown in the figure), which is disposed at the sewage outlet 4202 and is used to open or close the sewage outlet 4202.

[0163] The drain valve can remain closed during the washing process to prevent wash water from leaking out through the drain chamber 4201 and drain hole 4202. Alternatively, the drain valve can be opened during the draining process, allowing used wash water to be discharged to the outside through the drain chamber 4201 and drain hole 4202.

[0164] Alternatively, the drain valve can be a solenoid valve.

[0165] Please refer to the following: Figure 12 , Figure 13 and Figure 16 In some embodiments, the inlet shell 43 has a first connecting hole 4303 communicating with the outlet chamber 4101 and a second connecting hole 4304 communicating with the drain chamber 4201. The first axis 001 coincides with the central axis of the first connecting hole 4303, and the second axis 002 coincides with the central axis of the second connecting hole 4304.

[0166] It is understood that the washing pump housing 41 and the water inlet housing 43 can be manufactured based on the first axis 001, and the sewage pump housing 42 and the water inlet housing 43 can be manufactured based on the second axis 002. This makes the washing and sewage pump 40 provided in this embodiment easy to manufacture.

[0167] Please continue reading Figure 16 In some embodiments, the first axis 001 and the second axis 002 are located on the same side of the bottom wall of the water inlet cavity 4301 along a third direction, and the second axis 002 is located on the side of the first axis 001 that is close to the bottom wall of the water inlet cavity 4301.

[0168] Optionally, the second axis 002 is lower than the first axis 001, and at least a portion of the second connecting hole 4304 is located on the side of the first connecting hole 4303 near the bottom wall of the water inlet chamber 4301. Water in the water inlet chamber 4301 of the water inlet shell 43 can more easily enter the drain chamber 4201, which is beneficial for discharging sewage (washing water after use).

[0169] Please continue reading Figure 16 The lowest position of the second connecting hole 4304 is not higher than the lowest position of the bottom wall of the water inlet cavity 4301. In this way, the dirt on the bottom wall of the water inlet cavity 4301 can be discharged through the second connecting hole 4304, which helps to avoid residual dirt in the water inlet cavity 4301.

[0170] Optionally, the bottom wall of the water inlet chamber 4301 is provided with a groove 43011 that is recessed in a direction away from the second axis 002. In this way, dirt in the water inlet chamber 4301 can settle into the groove 43011, and residual wastewater in the water inlet chamber 4301 is concentrated in the groove 43011, which helps to prevent residual wastewater in the water inlet chamber 4301 from entering the water outlet chamber 4101 of the washing pump housing 41.

[0171] Please refer to the following: Figure 16 and Figure 17 In some embodiments, the washing pump provided in this application further includes a first drive assembly 44, which includes a first drive member 441 and a first impeller 442. The first drive member 441 is connected to the washing pump housing 41, and the drive shaft of the first drive member 441 is connected to the first impeller 442. The first impeller 442 is located in the water outlet chamber 4101 and is used to introduce water from the water inlet chamber 4301 into the water outlet chamber 4101 and discharge it through the water outlet hole 4102. In this way, the washing sewage pump 40 provided in this application can use the first drive assembly 44 to introduce water from the water inlet chamber 4301 into the water outlet chamber 4101 and discharge it through the water outlet hole 4102.

[0172] The drive shaft of the first drive component 441 can be a first drive shaft 4411.

[0173] Optionally, to avoid interference between the first drive member 441 and the water inlet housing 43, the first drive member 441 is located on the side of the washing pump housing 41 away from the water inlet housing 43.

[0174] Optionally, the sewage pump provided in this embodiment further includes a second drive assembly 45, which includes a second drive member 451 and a second impeller 452. The second drive member 451 is connected to the sewage pump housing 42, and the drive shaft of the second drive member 451 is connected to the second impeller 452. The second impeller 452 is located in the sewage discharge chamber 4201 and is used to introduce water from the inlet chamber 4301 into the sewage discharge chamber 4201 and discharge it through the sewage discharge hole 4202. In this way, the washing sewage pump 40 provided in this embodiment can also utilize the second drive assembly 45 to introduce water from the inlet chamber 4301 into the sewage discharge chamber 4201 and discharge it through the sewage discharge hole 4202. Furthermore, the washing sewage pump 40 provided in this embodiment can have both circulation and sewage discharge functions.

[0175] The drive shaft of the second drive component 451 can be a second drive shaft 4511.

[0176] Optionally, to avoid interference between the second drive member 451 and the inlet housing 43, the second drive member 451 is located on the side of the sewage pump housing 42 away from the inlet housing 43.

[0177] Please continue reading Figure 17In some embodiments, the first impeller 442 includes a first mounting hole 5307 that extends through both axial end faces of the first impeller 442, and the drive shaft of the first drive member 441 is connected to the first mounting hole 5307. In this way, the drive shaft of the first drive member 441 can drive the first impeller 442 to rotate.

[0178] Optionally, the first mounting hole 5307 is coaxially arranged with the first impeller 442.

[0179] Optionally, the first impeller 442 also includes a plurality of flow channels communicating with the first mounting hole 5307. The flow channels penetrate the peripheral wall of the first impeller 442, and the plurality of flow channels are arranged at intervals around the first mounting hole 5307.

[0180] In this way, the water entering the outlet chamber 4101 can enter the guide channel through the first mounting hole 5307 and flow out to the surroundings through the peripheral wall of the first impeller 442, which is conducive to the water in the inlet chamber 4301 entering the outlet chamber 4101.

[0181] Please see Figure 18 and Figure 19 In some embodiments, multiple flow channels are spirally arranged around the first mounting hole 5307, which makes the flow channels less prone to clogging and helps improve the reliability of the washing and sewage pump 40.

[0182] Optionally, the axis of the water outlet 4102 is spaced apart from the axis of the first impeller 442, and the axial direction of the water outlet 4102 is perpendicular to the axial direction of the first impeller 442. In this way, water in the guide channel can more easily enter the water outlet 4102.

[0183] Please continue reading Figure 17 In some embodiments, the drive shaft of the first drive member 441 is a hollow shaft, and the first drive member 441 further includes a support shaft 4412 sleeved inside the hollow shaft. One end of the support shaft 4412 passes through at least a portion of the first impeller 442 and is connected to the washing pump housing 41. In this way, the washing sewage pump 40 provided in this application embodiment can use the support shaft 4412 to support the drive shaft of the first drive member 441, and can avoid interference between the support shaft 4412 and the first impeller 442.

[0184] Optionally, a support component may be provided between the hollow shaft and the support shaft 4412.

[0185] For example, the support component can be a bearing.

[0186] For example, the support component can be a support sleeve.

[0187] Please refer to the following: Figure 12 , Figure 17 ,Figure 18 and Figure 19 In some embodiments, the washing pump housing 41 is provided with a connecting rod 46, one end of which has a connecting hole 461. One end of the support shaft 4412 extends into the connecting hole 461, and the other end of the connecting rod 46 is fixedly connected to the wall of the first communicating hole 4303. In this way, the support shaft 4412 can be connected and fixed to the water inlet housing 43 to support the drive shaft of the first driving member 441.

[0188] Optionally, a connecting plate 462 can be provided at the other end of the connecting rod 46, and the connecting plate 462 is fixedly connected to the outer peripheral wall of the connecting rod 46 and the wall of the first connecting hole 4303 respectively.

[0189] Optionally, the projected area of ​​the connecting plate 462 along the axial direction of the first connecting hole 4303 is smaller than the area of ​​the first connecting hole 4303, so that the first connecting hole 4303 can normally connect the water inlet chamber 4301 and the water outlet chamber 4101.

[0190] Optionally, there are multiple connecting plates 462, and the multiple connecting plates 462 are arranged at intervals along the circumference of the first connecting hole 4303.

[0191] Optionally, please refer to the following as well. Figure 20 and Figure 21 The cleaning chamber 110 is provided with a mounting groove 112, and a circulation outlet 1121 is disposed in the mounting groove 112. The filter element 47 is installed in the mounting groove 112, that is, the filter element 47 is installed at the bottom of the cleaning chamber 110 through the mounting groove 112. The filter element 47 can filter the washing water that enters the washing pump and the sewage pump from the circulation outlet 1121 in the cleaning chamber 110.

[0192] Optionally, the mounting groove 112 is located at the bottom of the cleaning chamber 110, and the circulation outlet 1121 is located on the bottom wall of the mounting groove 112.

[0193] Optionally, the first filter screen 4713 is arranged in an arc shape, which can increase the area of ​​the first filter screen 4713, thereby increasing the number of first filter holes 47131, which is beneficial to improving the filtration effect.

[0194] Optionally, the first filter screen 4713 is flat, which helps to improve the uniformity of force distribution throughout the first filter screen 4713 and facilitates manufacturing.

[0195] Optionally, the second filter screen 4714 is arranged in an arc shape, which can increase the area of ​​the second filter screen 4714, thereby increasing the number of second filter holes 47141, which is beneficial to improving the filtration effect.

[0196] Optionally, the second filter screen 4714 is flat, which helps to improve the uniformity of force distribution throughout the second filter screen 4714 and facilitates manufacturing.

[0197] Please see Figure 12 , Figure 15 and Figure 20 In some embodiments, the first filter hole 47131 and the second filter hole 47141 are arranged at an angle. This facilitates the connection of the first filter hole 47131 and the second filter hole 47141 to the inlet of different pumps, that is, the first filter hole 47131 can be connected to the inlet of the washing pump and the second filter hole 47141 can be connected to the inlet of the sewage pump.

[0198] Therefore, filter element 47 can filter the washing water entering the washing pump and the sewage pump respectively, thereby improving the integration.

[0199] For example, the first filter hole 47131 and the second filter hole 47141 are offset circumferentially along the filter channel 4711.

[0200] For example, the first filter hole 47131 and the second filter hole 47141 are arranged circumferentially between the filter channel 4711.

[0201] In this way, with the first filter hole 47131 and the second filter hole 47141 spaced apart circumferentially along the filter channel 4711, the first filter hole 47131 and the second filter hole 47141 can be positioned axially (e.g., along the filter channel 4711) in the filter channel 4711. Figure 12 Located in the same position as the filter channel 4711 in the Z direction, it is advantageous to arrange the first filter hole 47131 and the second filter hole 47141.

[0202] Optionally, the axial direction of the first filter hole 47131 intersects the axial direction of the second filter hole 47141.

[0203] Furthermore, when the axial direction of the first filter hole 47131 intersects the axial direction of the second filter hole 47141, the axial direction of the washing pump and the axial direction of the sewage pump can also intersect. That is, the washing pump has a first axis 001, the sewage pump has a second axis 002, and the extending direction of the first axis 001 (e.g., Figure 12 The X direction in the middle can intersect with the extension direction of the second axis 002 (e.g., Figure 12 (in the Y direction). This helps to reduce the size of the pump assembly, thereby reducing the space occupied by the pump assembly.

[0204] Optionally, please refer to Figure 13 The axial direction of the first filter hole 47131 is perpendicular to the axial direction of the second filter hole 47141.

[0205] Please refer to the following:Figure 12 , Figure 15 and Figure 20 In some embodiments, at least a portion of the second filter hole 47141 is located on the side of the first filter hole 47131 away from the inlet 4712.

[0206] It is understandable that washing wastewater is more likely to concentrate at the end of the filter channel 4711 away from the inlet 4712. The filter element 47 provided in this application embodiment has at least a portion of the second filter hole 47141 disposed on the side of the first filter hole 47131 away from the inlet 4712, which can filter the washing wastewater and facilitate the timely discharge of the washing wastewater, thereby avoiding the clogging of the first filter hole 47131 by dirt in the washing wastewater to a certain extent.

[0207] Please continue reading Figure 20 For example, the inlet 4712 is located at one end of the filter tube 471, and the other end of the filter tube 471 is closed. In this way, the axis of the filter channel 4711 is the axis of the filter tube 471, which facilitates processing.

[0208] Please see Figure 15 The filter element 47 also includes a first hand grip 473 disposed on the mounting component 472. The first hand grip 473 is easy to be gripped by a human hand or a clamping tool, thereby facilitating the removal and placement of the filter element 47.

[0209] Optionally, the first handheld part 473 is located on one side of the mounting part 472 along the axial direction of the filter channel 4711.

[0210] For example, the first hand-held part 473 is connected to the upper part of the mounting part 472.

[0211] Optionally, the first handheld part 473 and the first filter hole 47131 are located on different sides of the mounting part 472.

[0212] Optionally, the farthest surface of the first handheld part 473 away from the first filter hole 47131 is not higher than the farthest surface of the mounting part 472 away from the first filter hole 47131. Optionally, the top surface of the first handheld part 473 is not higher than the top surface of the mounting part 472. This can prevent the first handheld part 473 from being scratched or bumped during installation, transportation or use, which helps to improve safety.

[0213] Please see Figure 20 In some embodiments, the filter element 47 further includes a positioning part 474, which is disposed on the mounting part 472 and is used to engage with the body 20. In this way, the filter element 47 provided in this embodiment can be conveniently and stably installed on the inner wall of the cleaning chamber 110.

[0214] Optionally, the positioning part 474 is mounted on the bottom of the mounting part 472. That is, the filter element 47 can be mounted on the bottom wall of the cleaning chamber 110.

[0215] Optionally, please refer to Figure 21 The bottom wall of the mounting slot 112 of the body 20 is provided with a snap-fit ​​part 1122, which is used to snap-fit ​​with the positioning part 474.

[0216] Optionally, please refer to Figure 20 The positioning portion 474 protrudes from the surface of the mounting member 472, which facilitates the engagement of the positioning portion 474 and the snap-fit ​​member 1122. In addition, compared to the positioning portion 474 being recessed in the surface of the mounting member 472, the positioning portion 474 protruding from the surface of the mounting member 472 can help reduce the size of the mounting member 472.

[0217] In some embodiments, the first filter hole 47131 and the second filter hole 47141 are disposed on one side of the mounting member 472, and the positioning part 474 is disposed on the side of the mounting member 472 facing the first filter hole 47131. In this way, while the filter element 47 is installing onto the filter tube 471, the positioning part 474 can be snapped into the snap-fit ​​member 1122, facilitating installation. Furthermore, the filter element 47 provided in this embodiment can be positioned using the positioning part 474, enabling the first filter screen 4713 and the second filter screen 4714 to be installed in the accurate position.

[0218] Optionally, the first handle 473 and the positioning part 474 are located on different sides of the mounting part 472. This facilitates the positioning and installation of the filter element 47 by clamping the first handle 473.

[0219] Optionally, the positioning part 474 is provided with a cavity 4741, which can save materials. In addition, the positioning part 474 with a cavity 4741 is easier to deform, which facilitates the engagement of the positioning part 474 and the snap-fit ​​part.

[0220] Furthermore, the cavity 4741 is provided in the positioning part 474, and the depth of the cavity 4741 can be increased by utilizing the size of the positioning part 474, which is beneficial for saving materials and reducing the overall size of the filter element 47.

[0221] The cleaning machine 100 provided in this application includes the filter element 47 of any of the above embodiments. The cleaning machine 100 provided in this application has the same or similar technical effects as the filter element 47 of any of the above embodiments, and will not be described again here.

[0222] In some embodiments, the cleaning machine 100 provided in this application also includes a filter screen (not shown in the figure), which abuts between the machine body 20 and the filter element 47.

[0223] Understandably, the filter screen can further filter the water filtered by the filter element 47, which helps to improve the filtration effect.

[0224] It is understandable that the filter screen can be configured with a first mesh corresponding to the first filter hole 47131, and can also be configured with a second mesh corresponding to the second filter hole 47141.

[0225] Optionally, the aperture of the first mesh is smaller than the aperture of the second mesh.

[0226] Optionally, the spray device 30 provided in this embodiment further includes a spray pipe 36, which is disposed on the first shelf 31. The spray pipe 36 communicates with the cavity 4741 of the water supply shaft 37, and can spray cleaning fluid toward the items to be cleaned on the first shelf 31. It should be noted that the structure of the spray pipe 36 is not limited here.

[0227] Optionally, please refer to the following as well. Figure 3 and Figure 8 The spray device 30 provided in this embodiment of the application also includes a drying pipe 35, which can be supplied with hot air and can blow hot air onto the first shelf 31 and the second shelf 32, thereby drying the items washed in the cleaning chamber 110. The drying pipe 35 can be disposed inside the cleaning chamber 110.

[0228] Optionally, the drying pipe 35 can be installed on the first shelf 31 of the spray device 30. For example, the drying pipe 35 is fixed to the bottom of the first shelf 31 and can dry the items to be dried carried on the spray device 30.

[0229] Optionally, please refer to Figure 22 and Figure 23 The drying pipe 35 may include a connecting frame 353, and the drying pipe 35 can be installed on the spray device 30 through the connecting frame 353.

[0230] The drying duct 35 provided in this embodiment includes a first airflow channel 351, which has an air inlet 3501 and a main body portion 3511 that communicates with the air inlet 3501 and is annular. In this way, hot air can enter the first airflow channel 351 from the air inlet 3501 and flow along the main body portion 3511 of the first airflow channel 351, thereby increasing the flow path of the hot air.

[0231] Optionally, the main body 3511 of the first airflow channel 351 can be circular, polygonal, or elliptical.

[0232] For example, when the main body portion 3511 of the first airflow channel 351 is annular, the main body portion 3511 extends around the circular closed line.

[0233] For example, when the main body portion 3511 of the first airflow channel 351 is a polygon, the main body portion 3511 extends around the polygonal closing line, which can be a multi-line segment connected end to end.

[0234] For example, when the main body portion 3511 of the first airflow channel 351 is elliptical, the first airflow channel 351 extends around the elliptical closed line.

[0235] In this way, the shape of the main body 3511 of the first airflow channel 351 can be specifically set according to product requirements, which has good applicability.

[0236] Please continue reading Figure 22 and Figure 23 The drying pipe 35 provided in this embodiment further includes a plurality of second airflow channels 352, which are connected to the main body portion 3511 of the first airflow channel 351 and are in communication with the first airflow channel 351. Specifically, the second airflow channels 352 are directly connected to the main body portion 3511.

[0237] Optionally, both the first airflow channel 351 and the second airflow channel 352 are provided with an air outlet 3502.

[0238] In this way, hot air can be discharged from the air outlet 3502 of the first airflow channel 351 or from the air outlet 3502 of the second airflow channel 352. That is, hot air is discharged from different air outlets 3502, so that the items to be dried can be dried from multiple locations.

[0239] In addition, hot air can enter the second airflow channel 352 from the first airflow channel 351 and then be discharged from the air outlet 3502 of the second airflow channel 352. The second airflow channel 352 can increase the flow path of hot air, which is conducive to the hot air being discharged from different air outlets 3502 of the second airflow channel 352. Thus, the items to be dried can be dried from multiple positions, thereby improving the drying efficiency.

[0240] Therefore, the drying pipe 35 provided in this embodiment can improve drying efficiency.

[0241] Please continue reading Figure 22 and Figure 23In some embodiments, the second airflow channel 352 is connected to the outer periphery of the first airflow channel 351. It is understood that when the second airflow channel 352 is connected to the outer periphery of the first airflow channel 351, the hot air in the first airflow channel 351 needs to flow outwards, thus exceeding the range defined by the first airflow channel 351. Therefore, the drying pipe 35 provided in this application embodiment, by placing the second airflow channel 352 on the outer periphery of the first airflow channel 351, can increase the flow range of the hot air.

[0242] Furthermore, the air outlet 3502 can be located not only on the first airflow channel 351, but also on the second airflow channel 352, thus the air outlet 3502 can extend beyond the range defined by the first airflow channel 351. Therefore, the second airflow channel 352 can increase the arrangement range of the air outlet 3502, which is beneficial to improving drying efficiency.

[0243] Please continue reading Figure 22 and Figure 23 In some embodiments, the extending direction of the second airflow channel 352 is tangent to the extending direction of the first airflow channel 351. It is understood that when the extending direction of the first airflow channel 351 is tangent to the extending direction of the second airflow channel 352, at the connection point between the first and second airflow channels 351, the flow direction of the hot air in the first airflow channel 351 can be the same as the flow direction of the hot air in the second airflow channel 352. This results in less resistance to the hot air in the first airflow channel 351 entering the second airflow channel 352, facilitating the entry of the hot air from the first airflow channel 351 into the second airflow channel 352.

[0244] Please continue reading Figure 22 and Figure 23 In some examples, the extension direction of the second airflow duct 352 may be parallel to the plane containing the main body portion 3511 of the first airflow duct 351. In this way, the second airflow duct 352 can increase the flow range of hot air in a direction parallel to the plane containing the main body portion 3511 of the first airflow duct 351.

[0245] In some embodiments, the connection points of the plurality of second airflow channels 352 with the main body portion 3511 are equally spaced. This allows hot air from the first airflow channel 351 to enter the plurality of second airflow channels 352 evenly. Furthermore, the plurality of second airflow channels 352 can evenly discharge hot air to the outside through their own air outlets 3502.

[0246] In other examples, the extension direction of the second airflow duct 352 may also intersect with the plane containing the main body portion 3511 of the first airflow duct 351. In this way, the second airflow duct 352 can increase the flow range of hot air in the direction intersecting with the plane containing the main body portion 3511 of the first airflow duct 351.

[0247] Understandably, the extension direction of the second airflow channel 352 can be specifically set according to product requirements, making it highly adaptable.

[0248] Please continue reading Figure 22 and Figure 23 In some embodiments, the first end 3521 of the second airflow channel 352 is connected to the main body portion 3511 of the first airflow channel 351, and the second end 3522 of the second airflow channel 352 is closed.

[0249] It is understandable that when the second end 3522 of the second airflow duct 352 is open, the hot air in the second airflow duct 352 can flow out from the second end 3522 without changing its flow direction. This will cause the hot air in the first airflow duct 351 to preferentially enter the second airflow duct 352 which is closer to the air inlet 3501, affecting the usage effect of other second airflow ducts 352, and thus affecting the drying effect of the drying positions corresponding to other second airflow ducts 352.

[0250] Therefore, the drying pipe 35 provided in this embodiment of the application seals the second end 3522 of the second airflow channel 352, preventing hot air in the first airflow channel 351 from leaking from the second end 3522 of the second airflow channel 352. The hot air in the first airflow channel 351 can enter the multiple second airflow channels 352 as evenly as possible, which is beneficial to improving the drying effect.

[0251] Please continue reading Figure 22 and Figure 23 In some embodiments, the first airflow channel 351 provided in this application embodiment further includes an air intake portion 3512, which is connected to and communicates with the main body portion 3511, and an air inlet 3501 is provided at the third end 35121 of the air intake portion 3512.

[0252] Optionally, the third end 35121 of the air intake section 3512 is connected to the main body 3511 of the first airflow passage 351, and the fourth end 35122 of the air intake section 3512 is connected to the air intake port 3501.

[0253] In this way, the air inlet 3501 can be connected to the hot air source, and the hot air can enter the main body 3511 of the first airflow channel 351 from the air inlet 3501 through the air intake part 3512 of the first airflow channel 351. The air intake part 3512 facilitates the connection between the drying pipe 35 and the hot air source.

[0254] In some embodiments, the second end 3522 of the second airflow passage 352 is located on one side of the first end 3521 of the second airflow passage 352 along one of the counterclockwise and clockwise directions of the first airflow passage 351, and the fourth end 35122 of the intake portion 3512 is located on the other side of the third end 35121 of the intake portion 3512 along the other of the counterclockwise and clockwise directions of the first airflow passage 351.

[0255] In this way, the flow direction of hot air in the air intake section 3512, the main body section 3511 of the first airflow channel 351 and the second airflow channel 352 can be either clockwise or counterclockwise, which facilitates the flow of hot air.

[0256] For example, the second end 3522 of the second airflow passage 352 is located at the first end 3521 of the second airflow passage 352 in a counterclockwise direction along the first airflow passage 351 (e.g., Figure 22 On one side of the J direction in the middle, the fourth end 35122 of the intake section 3512 is located at the third end 35121 of the intake section 3512 along the clockwise direction of the first airflow passage 351 (e.g., in the J direction). Figure 22 The side opposite to the direction of J. Among them, the flow direction of hot air in the air intake part 3512, the main body part 3511 of the first airflow channel 351 and the second airflow channel 352 can all be counterclockwise.

[0257] Please continue reading Figure 22 and Figure 23 In some embodiments, the air intake portion 3512 is located on the outer periphery of the first airflow channel 351. In this way, the air intake portion 3512 can increase the distance between the first airflow channel 351 and the air inlet 3501, which is beneficial for the first airflow channel 351 to be arranged closer to the item to be dried.

[0258] In some embodiments, the connection position between the air intake portion 3512 and the main body portion 3511 is equally spaced from the connection positions between the plurality of second airflow channels 352 and the main body portion 3511. It can be understood that the connection position between the air intake portion 3512 and the main body portion 3511 is a first connection position, and the connection positions between the second airflow channels 352 and the main body portion 3511 are second connection positions, with the first connection position and the plurality of second connection positions equally spaced. That is, the main body portion 3511 includes a plurality of equally spaced connection positions, one of which is the first connection position, and the remaining connection positions are the second connection positions.

[0259] In this way, the hot air from the intake section 3512 can enter the second airflow passage 352 evenly.

[0260] In some embodiments, the air intake portion 3512 of the first airflow channel 351 is tangent to the main body portion 3511, facilitating the entry of hot air from the air intake portion 3512 into the main body portion 3511. It is understood that when the main body portion 3511 of the first airflow channel 351 is tangent to the air intake portion 3512, the flow direction of the hot air in the air intake portion 3512 at the connection point between the main body portion 3511 and the air intake portion 3512 can be the same as the flow direction of the hot air in the main body portion 3511 of the first airflow channel 351. This results in less resistance to the hot air in the air intake portion 3512 entering the main body portion 3511, facilitating the entry of the hot air from the air intake portion 3512 into the main body portion 3511.

[0261] In some embodiments, the air outlet 3502 includes a first air outlet 35021 and a second air outlet 35022, wherein the first air outlet 35021 is located along a first airflow channel 351 and the second airflow channel 352 in a first direction (e.g., Figure 22 On one side of the Z direction in the first airflow channel 351 and the second airflow channel 352 along the first direction, the second air outlet 35022 is located on the other side of the first airflow channel 351 and the second airflow channel 352 along the first direction, the first direction being perpendicular to the plane where the main body part 3511 is located.

[0262] For example, please see Figure 22 The first air outlet 35021 is located on the H side of the first airflow channel 351 and the second airflow channel 352. Please refer to [link / reference]. Figure 23 The second air outlet 35022 is located on the I side of the first airflow channel 351 and the second airflow channel 352.

[0263] It is understandable that the air outlet 3502 is located on both sides of the first airflow channel 351 and the second airflow channel 352 along the first direction, which can blow hot air in different directions, thus improving drying efficiency.

[0264] In addition, when the first direction is vertical, the opening direction of the first air outlet 35021 or the second air outlet 35022 can be downward, so that the water in the drying pipe 35 can flow out.

[0265] For example, the opening direction of the second air outlet 35022 is downward.

[0266] Please continue reading Figure 22 and Figure 23 In some embodiments, the drying pipe 35 has a tubular structure and a pipe wall that extends in the same direction as the first airflow channel 351 and the second airflow channel 352. This makes the drying pipe 35 easier to manufacture.

[0267] Please see Figure 24In other embodiments, the drying pipe 35 can be a plate-like structure formed by injection molding or casting. The portion of the drying pipe 35 other than the first airflow channel 351 and the second airflow channel 352 can be a solid structure. That is, the first airflow channel 351 and the second airflow channel 352 are cavities 4741 disposed inside the drying pipe 35.

[0268] It is understandable that the drying duct 35 can be part of the wall panel of the washing machine 100 that forms the washing chamber 110. In this way, the first airflow channel 351 and the second airflow channel 352 can be integrated into the wall of the machine body 20 or the machine cover 10 that forms the washing chamber 110.

[0269] Optionally, the cleaning machine 100 provided in this application embodiment has the same or similar technical effects as the drying pipe 35 in any of the above embodiments, which will not be described again here.

[0270] Optionally, the drying duct 35 is located near the first shelf 31, and the air outlet 3502 is located towards the second shelf 32.

[0271] Please refer to the following: Figure 1 and Figure 25 In order to blow hot air into the drying duct 35 and the cleaning chamber 110, the cleaning machine 100 provided in this application embodiment includes a drying assembly 50.

[0272] Please refer to the following: Figure 26 and Figure 27 The drying assembly 50 provided in this application embodiment includes a fan 51, which can introduce air into the drying assembly 50, that is, blow air into the drying assembly 50 to form a wind.

[0273] The drying assembly 50 provided in this application embodiment also includes a heating element 52, which can generate heat. The heating element 52 is used to heat the air blown into the drying assembly 50 by the fan 51 to form hot air.

[0274] Optionally, the heating element 52 can be heated by electrical energy.

[0275] The drying assembly 50 provided in this application embodiment also includes an air duct 53, into which air heated by the heating element 52 can enter.

[0276] For example, the duct 53 includes an air inlet 5301, and a fan 51 is disposed at the air inlet 5301, through which the fan 51 blows air into the duct 53. A heating element 52 is disposed on the side of the fan 51 facing the air inlet 5301, thereby heating the air blown by the fan 51 from the air inlet 5301 into the duct 53, forming hot air. Optionally, the heating element 52 can be disposed between the fan 51 and the duct 53, thereby heating the air entering the duct 53.

[0277] Optionally, the heating element 52 can be located at the outlet of the fan 51.

[0278] Optionally, the heating element 52 can be located at the air inlet 5301.

[0279] Optionally, the heating element 52 may include a heating channel connecting the air inlet 5301 and the outlet of the fan 51.

[0280] Optionally, the duct 53 further includes a first air outlet 5302 and a second air outlet 5303 spaced apart. Exemplarily, the first air outlet 5302 and the second air outlet 5303 are along a first direction (e.g., Figure 26 The intervals are set in the Z direction. For example, the first direction can be the vertical direction.

[0281] For example, the second air outlet 5303 is higher than the first air outlet 5302. In this way, the air duct 53 can blow hot air to positions at different heights through the first air outlet 5302 and the second air outlet 5303, so that items at different heights or items at different heights can be blown with hot air at the same time, which helps to improve drying efficiency.

[0282] Therefore, the drying component 50 provided in this application is beneficial to improving drying efficiency.

[0283] For example, please refer to the following: Figure 25 , Figure 26 , Figure 27 and Figure 28 The first air outlet 5302 and the second air outlet 5303 can blow hot air onto the items to be dried on the shelves at different heights.

[0284] For example, the first air outlet 5302 can blow hot air toward the items to be dried on the first shelf 31, and the second air outlet 5303 can blow hot air toward the items to be dried on the second shelf 32.

[0285] Optionally, at least a portion of the first air outlet 5302 is located between the first shelf 31 and the second shelf 32, and the first air outlet 5302 is positioned closer to the first shelf 31.

[0286] In this way, the air duct 53 can blow hot air onto the items to be dried on the first shelf 31 through the first air outlet 5302.

[0287] Optionally, at least a portion of the second air outlet 5303 is located between the first shelf 31 and the second shelf 32, and the second air outlet 5303 is closer to the second shelf 32.

[0288] In this way, the air duct 53 can blow hot air onto the items to be dried on the second shelf 32 through the second air outlet 5303.

[0289] Optionally, the first air outlet 5302 can be connected to the air inlet 3501 of the drying duct 35, so that hot air can be blown into the drying duct 35.

[0290] Optionally, please refer to the following as well. Figure 11 , Figure 25 , Figure 26 , Figure 27 and Figure 28 The machine body 20 is provided with a first ventilation hole 2001 and a second ventilation hole 2002. The first ventilation hole 2001 is connected to the first air outlet 5302, and the second ventilation hole 2002 is connected to the second air outlet 5303. In this way, the air duct 53 can blow hot air into the machine body 20 through the first ventilation hole 2001, and thus directly blow hot air onto the items to be dried on the first shelf 31, thereby improving drying efficiency. Furthermore, the air duct 53 can blow hot air into the machine body 20 through the second ventilation hole 2002, and thus directly blow hot air onto the items to be dried on the second shelf 32, thereby improving drying efficiency.

[0291] In some embodiments, please continue reading Figure 26 and Figure 27 The opening direction of the air inlet 5301 is perpendicular to the opening direction of the first air outlet 5302. For example, the opening direction of both the air inlet 5301 and the first air outlet 5302 is perpendicular to the first direction (the interval direction between the first air outlet 5302 and the second air outlet 5303).

[0292] The opening direction of the air inlet 5301 can be parallel to... Figure 26 In the Y direction, the opening direction of the first air outlet 5302 can be parallel to... Figure 27 The X direction in the equation.

[0293] In this way, the air duct 53 can change the airflow direction of the hot air, thus adapting to the structure and spatial layout of the cleaning machine 100, making it highly adaptable.

[0294] Optionally, the opening direction of the first air outlet 5302 is the same as the opening direction of the second air outlet 5303.

[0295] Optionally, the diameter of the air inlet 5301 is larger than the diameters of the first air outlet 5302 and the second air outlet 5303, that is, the opening area of ​​the air inlet 5301 is larger than the opening areas of the first air outlet 5302 and the second air outlet 5303. The duct 53 includes a variable-diameter air duct 5304, which is located between the air inlet 5301 and the first air outlet 5302, and between the air inlet 5301 and the second air outlet 5303. In this way, the hot air entering the duct 53 from the air inlet 5301 can increase its velocity after passing through the variable-diameter air duct 5304, thereby increasing the velocity of the hot air discharged through the first air outlet 5302 and the second air outlet 5303.

[0296] Optionally, the variable diameter air duct 5304 is directly connected to the air inlet 5301.

[0297] In some embodiments, the diameter of the second air outlet 5303 is smaller than the diameter of the first air outlet 5302, that is, the opening area of ​​the second air outlet 5303 is smaller than the opening area of ​​the first air outlet 5302. Since hot air has a lower density and tends to rise more easily, the drying assembly 50 of this embodiment makes the diameter of the second air outlet 5303 smaller than the diameter of the first air outlet 5302, allowing hot air to be easily discharged from the lower-height first air outlet 5302.

[0298] The inventors discovered that the air inside the body 20 is humid, and the air inside the body 20 flows back to the air inlet 5301, which can easily damage the fan 51 and the heating element 52.

[0299] In some embodiments, the duct 53 further includes a backflow prevention duct 5305, which is located between the air inlet 5301 and the first air outlet 5302. This helps to prevent air inside the body 20 from flowing back from the first air outlet 5302 to the air inlet 5301 when the fan 51 is not working, thereby improving safety.

[0300] Optionally, the backflow prevention duct 5305 includes a bend 53052, which can prevent air backflow.

[0301] Optionally, the variable diameter air duct 5304 is located between the anti-backflow air duct 5305 and the air inlet 5301.

[0302] The anti-backflow air duct 5305 includes a first air duct section 53051, a bend section 53052, and a second air duct section 53053 connected in sequence. The first air duct section 53051 is connected to the air inlet 5301, and the second air duct section 53053 is connected to the first air outlet 5302.

[0303] Optionally, the first air duct section 53051 and the second air duct section 53053 are parallel.

[0304] Optionally, both the first air duct section 53051 and the second air duct section 53053 extend in the vertical direction (first direction).

[0305] Please continue reading Figure 26 and Figure 27 In some embodiments, the duct 53 includes at least two second air outlets 5303, that is, there are multiple second air outlets 5303.

[0306] In some examples, at least two second air outlets 5303 can be along a second direction (e.g. Figure 26 The X-direction interval is set, and the second direction is perpendicular to the first direction.

[0307] In this way, the drying assembly 50 provided in this embodiment of the application can further increase the blowing position of the air duct 53, so that more parts of the items to be dried can be blown by hot air at the same time, which can further improve the drying efficiency.

[0308] In other examples, at least two second air outlets 5303 are along the first direction (e.g. Figure 26 (Z-direction) interval settings.

[0309] Similarly, this setting helps to further increase the air blowing position of the air duct 53, so that more parts of the items to be dried can be blown by hot air at the same time, which helps to further improve the drying efficiency.

[0310] For example, the first direction can be vertical, meaning that at least two second air outlets 5303 are at different heights. This arrangement allows the air duct 53 to blow hot air to more positions at different heights, enabling more positions at different heights of the items to be dried, or more items at different heights, to be blown by hot air simultaneously, thus improving drying efficiency.

[0311] In some other embodiments, at least two second air outlets 5303 are spaced apart along both the first and second directions. Similarly, this arrangement helps to further increase the airflow position of the air duct 53, allowing more areas of the items to be dried to be simultaneously exposed to hot air, thus further improving drying efficiency.

[0312] Please continue reading Figure 27 In some embodiments, the duct 53 includes an extension duct 5306 located between the air inlet 5301 and the second air outlet 5303, through which hot air at the air inlet 5301 can flow to the second air outlet 5303.

[0313] Optionally, the extended air duct 5306 is connected to the anti-backflow air duct 5305. Hot air at the air inlet 5301 can enter the extended air duct 5306 through the anti-backflow air duct 5305, and then flow to the second air outlet 5303 through the extended air duct 5306.

[0314] Optionally, the extended air duct 5306 is connected to the bend 53052 of the anti-backflow air duct 5305 and the connection point of the second air duct section 53053.

[0315] Optionally, the extended air duct 5306 corresponds to the second air duct section 53053. The extended air duct 5306 and the second air duct section 53053 extend in the same direction.

[0316] Please continue reading Figure 27 In some embodiments, the inner wall of the blower duct 53 is provided with a diversion section 54, which is located at the connection between the extended air duct 5306 and the anti-backflow air duct 5305.

[0317] Optionally, the diversion section 54 protrudes towards the bend 53052 of the anti-backflow duct 5305, and the bend 53052 includes a section along a first direction (e.g., Figure 27 The first edge 53054 and the second edge 53055 are spaced apart in the Z direction. Along the first direction, the diversion part 54 is located between the first edge 53054 and the second edge 53055.

[0318] In this way, the diversion section 54 can disperse the hot air at the bend section 53052 into two parts, one part can flow to the first air outlet 5302 and the other part can flow to the second air outlet 5303, so that both the first air outlet 5302 and the second air outlet 5303 can blow out hot air.

[0319] Optionally, the dimension of the diversion section 54 in the first direction gradually decreases along the direction close to the bend section 53052.

[0320] In this way, the diversion section 54 can guide the hot air of the bending section 53052, making it easier for the hot air of the bending section 53052 to be dispersed into two parts.

[0321] In some embodiments, the side of the diverter 54 facing the second air outlet 5303 is a concave arc surface. In this way, the diverter 54 can make it easier for hot air to flow towards the second air outlet 5303, thereby improving the airflow guiding effect.

[0322] In some embodiments, the side of the diverter 54 facing the first air outlet 5302 is a concave arc surface. In this way, the diverter 54 can make it easier for hot air to flow towards the first air outlet 5302, thereby improving the airflow guiding effect.

[0323] In some embodiments, the sides of the diverter 54 facing the second air outlet 5303 and the sides facing the first air outlet 5302 are both concave arc surfaces. In this way, the diverter 54 can make it easier for hot air to flow towards the second air outlet 5303 and the first air outlet 5302, thereby improving the airflow guiding effect.

[0324] Please continue reading Figure 27 In some embodiments, the first edge 53054 is closer to the first air outlet 5302 than the second edge 53055. That is, the edge of the bent portion 53052 facing the first air outlet 5302 is the second edge 53055, and the edge of the bent portion 53052 facing the second air outlet 5303 is the first edge 53054.

[0325] Optionally, the opening area of ​​the first air outlet 5302 is smaller than the opening area of ​​the second air outlet 5303, and along the first direction, the distance between the diversion part 54 and the first edge 53054 is smaller than the distance between the diversion part 54 and the second edge 53055.

[0326] Optionally, the area of ​​the first air outlet 5302 is larger than the area of ​​the second air outlet 5303, and along the first direction, the distance between the diversion part 54 and the first edge 53054 is greater than the distance between the diversion part 54 and the second edge 53055.

[0327] Optionally, the area of ​​the first air outlet 5302 is equal to the area of ​​the second air outlet 5303, and along the first direction, the distance between the diversion part 54 and the first edge 53054 is equal to the distance between the diversion part 54 and the second edge 53055.

[0328] In this way, the drying component 50 can distribute hot air as evenly as possible to the first air outlet 5302 and the second air outlet 5303, which is beneficial to improving the drying effect.

[0329] Please continue reading Figure 26 and Figure 27 The drying assembly 50 may include a mounting hole 5307, through which the drying assembly 50 can be connected to the body 20.

[0330] Optionally, mounting hole 5307 is provided on air duct 53.

[0331] The inventors discovered that the cleaning machine 100 is typically used to clean tableware, drinking containers (such as water cups and baby bottles), and other items that are to be cleaned. Since the items to be cleaned involve food and drink, users pay more attention to the cleaning effect.

[0332] However, in related technologies, the cleaning machine 100 places the items to be cleaned in a closed environment, and the user cannot directly feel the cleaning process, resulting in low trust and a poor user experience.

[0333] Please refer to the following: Figure 29 , Figure 30 and Figure 31 The machine cover 10 provided in this application embodiment includes a top plate 1, a side plate 2, and a second handheld part 3. The side plate 2 is connected to the edge of the top plate 1 and is integrally formed with the top plate 1. The second handheld part 3 is also integrally formed with the top plate 1. The top plate 1, the side plate 2, and the second handheld part 3 are all made of transparent material, which makes it easy to observe the cleaning situation inside the cleaning chamber 110 through the machine cover 10, which helps to increase user trust and thus improve the user experience.

[0334] Therefore, the cover 10 provided in this application embodiment can at least partially solve the technical problem of poor user experience.

[0335] Optionally, please refer back to the previous section. Figure 11 The body 20 includes a first connecting part 210 and a second connecting part 220, and the cover 10 can be connected to the first connecting part 210 and the second connecting part 220.

[0336] Alternatively, the side panels 2 of the hood 10 may be perpendicular to the top panel 1.

[0337] Optionally, the hood 10 may have multiple side panels 2, and the multiple side panels 2 may be connected to different edges of the top plate 1. Alternatively, the hood 10 may have a single side panel 2, which has at least one bent portion 53052, and the side panel 2 may be connected to different edges of the top plate 1.

[0338] In some embodiments, the top plate 1 has a vent 101, which can communicate with the cleaning chamber 110. In this way, the gas in the cleaning chamber 110 can be discharged upward through the vent 101.

[0339] Optionally, the vent 101 can be an arc-shaped elongated hole, which helps to increase the area of ​​the vent 101.

[0340] In some embodiments, the side plate 2 includes a fifth end 21 and a sixth end 22 opposite to each other. The fifth end 21 of the side plate 2 is connected to the top plate 1, and the sixth end 22 of the side plate 2 can be sealed to the body 20. In this way, the machine cover 10 provided in this application can be sealed to the body 20 of the cleaning machine 100 through the side plate 2.

[0341] Optionally, the fifth end 21 is located at the top of the side plate 2, and the sixth end 22 is located at the bottom of the side plate 2.

[0342] Optionally, the edge of the end face of the sixth end 22 of the side plate 2 is provided with a chamfer 2201. This facilitates the fit between the side plate 2 and the body 20.

[0343] Alternatively, the chamfer 2201 can be a rounded corner or a beveled corner.

[0344] Please continue reading Figure 29 , Figure 30 and Figure 31 In some embodiments, the second hand-held part 3 is provided with a hand-held groove 301.

[0345] In this way, the second hand-held part 3 can be held through the hand-held slot 301 to pick up and put down the cover 10.

[0346] Optionally, the second hand-held part 3 includes a first hand-held plate 302 and a second hand-held plate 303 disposed opposite each other in a vertical direction, and a hand-held groove 301 is located between the first hand-held plate 302 and the second hand-held plate 303. The second hand-held plate 303 is located below the first hand-held plate 302 and is recessed downward.

[0347] Understandably, the downward recess of the second hand-held plate 303 can increase the space of the hand-held slot 301 without increasing the height of the machine cover 10. In other words, with the space of the hand-held slot 301 remaining unchanged, setting the second hand-held plate 303 to be recessed downward can reduce the height of the second hand-held part 3, thereby helping to reduce the height of the machine cover 10, and thus reducing the height of the cleaning machine 100.

[0348] In some embodiments, an exhaust hole 101 is formed in the gap between the second hand grip 3 and the top plate 1. The exhaust hole 101 can be formed during the processing of the second hand grip 3 and the top plate 1, which reduces the need for additional processing steps for the exhaust hole 101, thus making the exhaust hole 101 easy to form.

[0349] When cleaning items, the cleaning machine 100 usually uses hot water to improve the cleaning effect. Water vapor is also generated when the items are steam sterilized. Therefore, the cleaning machine 100 can exhaust the air through the exhaust port 101 during the cleaning process.

[0350] The inventors discovered that during the cleaning process of the washing machine 100, the spray water would splash out from the exhaust port 101, affecting the user experience.

[0351] Please continue reading Figure 29 , Figure 30 and Figure 31 In some embodiments, the machine cover 10 provided in this application also includes a first water baffle 4, which is connected to the top plate 1 facing the cleaning chamber 110 (see [link]). Figure 11 One side of the top plate 1, that is, the first water baffle 4 is connected to the inner side of the top plate 1.

[0352] In this configuration, at least a portion of the first baffle plate 4 is spaced apart from the side plate 2, and at least a portion of the orthographic projection of the top plate 1 in the vertical direction covers the vent hole 101.

[0353] In this way, the first baffle plate 4 can block the exhaust port 101. When the spray water in the cleaning machine 100 is sprayed toward the exhaust port 101, it will be blocked by the first baffle plate 4. The first baffle plate 4 helps to prevent the spray water in the cleaning machine 100 from splashing directly out of the exhaust port 101, which helps to improve the user experience.

[0354] In some embodiments, the machine cover 10 provided in this application further includes a second baffle 5, which is connected to the side of the top plate 1 facing the cleaning chamber 110, that is, the first baffle 4 is connected to the inner side of the top plate 1. In addition, at least a portion of the second baffle 5 extends in a direction perpendicular to the top plate 1.

[0355] In this way, the second baffle plate 5 can block the spray water in the direction parallel to the top plate 1. The second baffle plate 5 also helps to prevent the spray water in the cleaning machine 100 from splashing out of the exhaust port 101, which further helps to improve the user experience.

[0356] Optionally, the second baffle 5 is located on at least one side of the first baffle 4 in a direction perpendicular to the extension direction of the first baffle 4 and parallel to the top plate 1.

[0357] Optionally, the first baffle plate 4 and the top plate 1 enclose an exhaust groove 401, and the exhaust hole 101 communicates with the exhaust groove 401. The exhaust groove 401 has an opening on at least one side in a direction perpendicular to the extension direction of the first baffle plate 4 and parallel to the plane of the top plate 1. In this way, the gas in the cleaning chamber 110 can enter the exhaust groove 401 through the opening and then be discharged through the exhaust hole 101.

[0358] Optionally, the second baffle plate 5 is located on the side where the trough opening is located, and is spaced apart from the trough opening. In this way, the second baffle plate 5 can prevent the spray water from entering the exhaust trough 401 through the trough opening, and does not affect the exhaust of the exhaust trough 401 and the exhaust hole 101.

[0359] Optionally, please refer to Figure 31 The exhaust groove 401 includes a bottom wall opposite to the top plate 1, and the distance between at least a portion of the bottom wall of the exhaust groove 401 and the top plate 1 gradually increases along the direction close to the groove opening.

[0360] In this way, the water formed by the condensation of moisture in the gas in the cleaning chamber 110 in the exhaust channel 401 can be discharged from the exhaust channel 401.

[0361] Please see Figure 32 In some embodiments, the machine cover 10 provided in this application further includes a skirt 6 connected to the bottom of the side plate 2. The skirt 6 is connected to the inner side of the side plate 2 and to the side of the side plate 2 near the cleaning chamber 110. For example, the skirt 6 is connected to the sixth end 22 of the side plate 2.

[0362] In this way, the machine cover 10 provided in this embodiment can be connected to the machine body 20 by the skirt 6, and the skirt 6 can form a double seal with the bottom (sixth end 22) of the side plate 2, which can improve the sealing performance and help prevent the cleaning machine 100 from leaking water.

[0363] Optionally, the side panel 2 includes an outer wall surface and an inner wall surface, and the skirt panel 6 also includes an outer wall surface and an inner wall surface.

[0364] Among them, the outer wall surface of the side panel 2 is the first wall surface 201, the inner wall surface of the side panel 2 is the second wall surface 202, the outer wall surface of the skirt panel 6 is the third wall surface 601, and the inner wall surface of the skirt panel 6 is the fourth wall surface 602.

[0365] Optionally, the outer wall surface (third wall surface 601) of the skirt panel 6 is spaced apart from the outer wall surface (first wall surface 201) of the side panel 2, and the outer wall surface of the skirt panel 6 is located on the side of the outer wall surface of the side panel 2 that is closer to the cleaning chamber 110.

[0366] In some embodiments, the inner wall surface (fourth wall surface 602) of the skirt panel 6 is located on the side of the inner wall surface (second wall surface 202) of the side panel 2 near the cleaning chamber 110. In the above embodiments, the outer wall surface of the skirt panel 6 is spaced apart from the outer wall surface of the side panel 2, and the outer wall surface of the skirt panel 6 is located on the side of the outer wall surface of the side panel 2 near the cleaning chamber 110.

[0367] In this way, in the embodiments of this application, the skirt plate 6 and the side plate 2 can be manufactured separately, and the skirt plate 6 does not restrict the thickness of the side plate 2, which is beneficial to reducing the thickness of the side plate 2 and saving materials. Of course, the skirt plate 6 and the side plate 2 can also be manufactured simultaneously, for example, the skirt plate 6 and the side plate 2 can be integrally formed.

[0368] Please see Figure 32 In some embodiments, the distance between the outer wall of the skirt 6 and the outer wall of the side plate 2 gradually increases along the direction from the fifth end 21 to the sixth end 22. That is, the outer wall of the skirt 6 is inclined inward from the edge (e.g., the lower edge) away from the fifth end 21, which facilitates the fit between the skirt 6 and the body 20.

[0369] Please see Figure 33 In some embodiments, the connecting surface between the skirt panel 6 and the side panel 2 slopes downwards from the side panel 2 towards the skirt panel 6. That is, the distance between the connecting surface between the skirt panel 6 and the side panel 2 and the center line extending vertically from the cleaning chamber 110 gradually decreases from top to bottom. In this way, the water sprayed onto the side panel 2 can flow back into the cleaning chamber 110 along the skirt panel 6, which helps to prevent washing water from adhering to the inner surface of the cover 10.

[0370] Optionally, the inner wall surface of the skirt panel 6 includes a transition surface 6021 and a main wall surface 6022. Along a direction perpendicular to the main wall surface 6022 and in the relative direction of the fifth end 21 and the sixth end 22 of the side panel 2, the main wall surface 6022 and the inner wall surface of the side panel 2 are spaced apart. The transition surface 6021 connects the main wall surface 6022 and the inner wall surface of the side panel 2. The transition surface 6021 is an inclined surface or a curved surface. That is, the main wall surface 6022 and the inner wall surface of the side panel 2 are spaced apart in both directions. For example, the transition surface 6021 can be the connecting surface between the skirt panel 6 and the side panel 2.

[0371] Understandably, when the washing machine 100 is operating, the water sprayed onto the inner wall of the side panel 2 can flow back along the transition surface 6021 to the main wall surface 6022, and then back into the washing chamber 110. Therefore, the water sprayed onto the inner wall of the side panel 2 can flow back along the inner wall of the side panel 6 into the washing chamber 110, which helps to prevent washing water from adhering to the inner surface of the machine cover 10.

[0372] Please refer to the following: Figure 1 , Figure 11 , Figure 33 and Figure 34 In some embodiments, the hood 10 provided in this application has at least one circumference that is open to the body 20. It is understood that the circumference of the hood 10 is the side where the top plate 1 or side plate 2 of the hood 10 is located relative to the center of the hood 10. The hood 10 may include multiple circumferences; for example, if the hood 10 is hexahedral, it may include six circumferences.

[0373] Therefore, with at least one side of the cover 10 open to the body 20, the cover 10 can be removed to expose the cleaning chamber 110, facilitating the entry and exit of items to be cleaned. The entry and exit of items to be cleaned into the cleaning chamber 110 refers to placing items into or removing items from the cleaning chamber 110.

[0374] For example, the hood 10 provided in this embodiment includes a first opening 102 and a second opening 103. The plane of the first opening 102 is parallel to the top plate 1, and the plane of the second opening 103 intersects the top plate 1. For example, if there are multiple side plates 2, the plane of the second opening 103 can be parallel to one of the side plates 2. It is understood that after the hood 10 is connected to the first connecting part 210 of the body 20, the body 20 can block the first opening 102, and after the hood 10 is connected to the second connecting part 220 of the body 20, the body 20 can block the second opening 103.

[0375] The first opening 102 is located on one side of the open hood 10, and the second opening 103 is located on the other side of the open hood 10.

[0376] In some embodiments, the cover 10 provided in this application also includes a magnetic member 8, which is located on one side of the second opening 103 and is used to attract the body 20.

[0377] In this way, the cover 10 provided in this application embodiment can be attracted to the body 20 by the magnetic attachment 8, thereby facilitating the installation and removal of the cover 10.

[0378] The body 20 is equipped with a component that can be magnetically attracted, or the body 20 is equipped with a magnetic component whose magnetic poles are opposite to those of the magnetic attractor 8. That is, the side of the magnetic attractor 8 facing the body 20 is the N pole, and the side of the magnetic component on the body 20 facing the magnetic attractor 8 is the S pole. Alternatively, the side of the magnetic attractor 8 facing the body 20 is the S pole, and the side of the magnetic component on the body 20 facing the magnetic attractor 8 is the N pole.

[0379] Optionally, the magnetic attractor 8 is a magnetically conductive component, and the housing 10 is provided with a magnet that guides the magnetic attractor 8.

[0380] Please see Figure 35 Optionally, the machine cover 10 provided in this application embodiment further includes a second reinforcing rib 7, which is disposed at the connection between the top plate 1 and the side plate 2. The second reinforcing rib 7 can increase the structural strength of the machine cover 10.

[0381] Please see Figure 35 Optionally, the first baffle plate 4 is arc-shaped. The extending direction of the first baffle plate 4 can be parallel to the extending direction of the vent hole 101.

[0382] Optionally, the second baffle plate 5 is arc-shaped. The extending direction of the second baffle plate 5 may be parallel to the extending direction of the vent hole 101.

[0383] Optionally, the second baffle plate 5 is provided with a first reinforcing rib 501 on the side opposite to the drainage channel. The first reinforcing rib 501 can increase the structural strength of the second baffle plate 5.

[0384] Optionally, the cleaning machine 100 provided in this application embodiment has the same or similar technical effects as the machine cover 10 described above.

[0385] Optionally, the cover 10 and the body 20 of the cleaning machine 100 are magnetically attached to each other, making it convenient to install and remove the cover 10.

[0386] In some embodiments, the housing 10 is provided with at least two magnetic elements. The cleaning machine 100 provided in this application embodiment includes a controller and a detection element electrically connected to the controller to detect the magnetic elements. The controller can determine whether the housing 10 and the body 20 are properly installed based on the detection results of the detection element.

[0387] It is understandable that the magnetic component 8 can be used as a magnetic component for detection by the detection element.

[0388] Optionally, the cleaning machine 100 provided in this application embodiment also includes an alarm electrically connected to the controller, which can control the alarm based on the detection results of the detection element. If the machine cover 10 and the machine body 20 are not installed in place, the controller can control the alarm to sound. If the machine cover 10 and the machine body 20 are installed in place, the controller can control the alarm not to activate.

[0389] For example, an alarm may include a speaker that can play an alarm sound.

[0390] For example, an alarm may include an indicator light that can emit alarm light.

[0391] Alternatively, the detection element can be a Hall switch.

[0392] The above are merely specific embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
