[0041] It should be noted that the definitions of directional terms such as "upper," "lower," "top," and "bottom" in this application are based on the orientation of the product when it is in normal use and placed upright. They should not be understood as specific limitations on the embodiments of this application. In addition, in the context, it is also necessary to explain that when it is mentioned that one element is connected to another element, it can be either a direct connection or an indirect connection, unless it is explicitly stated that one element is directly connected to another element.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0043] The specific implementation methods of the present application have been described in detail. Although some embodiments have been shown and described, it should be understood by those skilled in the art that these embodiments can be modified and improved without departing from the principles and spirit of the present application, the scope of which is defined by the claims and their equivalents.

[0044] According to the first aspect of the present application, a cleaning device is provided, for example but not limited to, the cleaning device may be a dishwasher. Figures 1 to 7 As shown, the cleaning device includes a washing chamber 10, a diverter chamber 30, a spray arm 40, and a diverter assembly. The washing chamber 10 is provided with multiple washing areas 20. The diverter chamber 30 is arranged on the outer wall of the washing chamber 10. The diverter chamber 30 has an inlet 321 and multiple branch outlets 311. The spray arm 40 is installed in the washing chamber 10. The spray arm 40 has multiple nozzles 41. The inlet of the nozzle 41 is connected to at least one corresponding branch outlet 311, and the discharge ports of the multiple nozzles 41 are respectively arranged toward the corresponding washing area 20. The diverter assembly is arranged in the diverter chamber 30. The diverter assembly can selectively connect the inlet 321 and the branch outlet 311, thereby controlling the water output of the corresponding nozzle 41.

[0045] According to the cleaning device provided in the embodiment of the present application, a plurality of washing areas 20 are provided in the washing chamber 10. When in use, the user can select a washing area according to the amount of cleaning, and operate to connect the inlet 321 and the branch outlet 311 corresponding to the washing area, thereby enabling the nozzle 41 of the corresponding spray arm 40 to discharge water, while the unselected nozzles 41 will not spray water, so that the amount of cleaning can be matched with the washing area 20, thereby avoiding energy waste. According to the cleaning device provided in the embodiment of the present application, when in use, the washing area corresponding to the amount of cleaning can be selected, thereby reducing the waste of water and electricity to a certain extent, achieving the purpose of saving energy.

[0046] According to the present application, the fluid enters the inner cavity of the diversion chamber 30 from the inlet 321 of the diversion chamber 30. When the diversion component connects the inlet 321 and a corresponding branch outlet 311, the fluid will flow out from the corresponding branch outlet 311, thereby flowing out through the corresponding nozzle 41 on the spray arm 40 and acting on the corresponding washing area 20, thereby achieving the purpose of matching the cleaning amount with the washing area 20, thereby saving energy.

[0047] According to the present application, the diversion chamber 30 is a split structure with a hollow interior. Figures 3 to 7 As shown, the diverter chamber 30 includes a support plate 31 and a diverter plate 32. The support plate 31 is connected to the bottom of the washing chamber 10, and the spray arm 40 is fixed to the support plate 31. The diverter plate 32 is disposed at the lower end of the support plate 31. The support plate 31 and the diverter plate 32 together form the diverter chamber 30, wherein a plurality of branch outlets 311 are formed on the support plate 31, and an inlet 321 is formed on the diverter plate 32. Specifically, the inlet 321 is a through hole formed in the diverter plate 32, and the plurality of branch outlets 311 are multiple through holes formed in the support plate 31.

[0048] In these embodiments, a flow diversion assembly is disposed within a flow diversion chamber 30, which is enclosed by a support plate 31 and a flow diversion plate 32 to form a removable flow diversion chamber 30, facilitating installation, replacement, or maintenance of the flow diversion assembly. Multiple branch outlets 311 are formed on the support plate 31, and inlets 321 are formed on the flow diversion plate 32. The flow diversion assembly, located within the flow diversion chamber 30, selectively connects the inlets 321 to different branch outlets 311, thereby achieving flow diversion. Compared to providing multiple branch pipes, this significantly saves space within the device, resulting in a more concise internal piping layout.

[0049] According to the present application, the diversion chamber 30 has an inner cavity, the inlet 321 is connected to the inner cavity of the diversion chamber 30, and the multiple branch outlets 311 can be selectively connected to the inner cavity of the diversion chamber 30, thereby realizing the diversion of the fluid entering the inner cavity of the diversion chamber 30 from the inlet 321.

[0050] In the prior art, there are many ways to divert flow, but these methods significantly affect the layout of internal components, resulting in a larger volume, which cannot meet the size requirements of existing household appliances and is inconvenient for the layout of internal components. In an embodiment, the diverter assembly includes a drive unit 51 and a baffle assembly 52. ​​The baffle assembly 52 is rotatably mounted on the diverter plate 32 and is located at the lower end of the multiple branch outlets 311 and is connected to the drive unit 51. The drive unit 51 is used to drive the baffle assembly 52 to rotate, thereby connecting or disconnecting the inlet 321 from the multiple branch outlets 311.

[0051] In these embodiments, by disposing a baffle assembly 50 at the lower ends of the plurality of branch outlets 311 and rotating the baffle assembly 52 relative to the plurality of branch outlets 311, the plurality of branch outlets 311 can be selectively connected to or blocked from the inner cavity of the diversion chamber 30, thereby selectively connecting or blocking the plurality of branch outlets 311 from the inlet 321. Furthermore, the embodiments of the present application have a simple structure, allowing for a reasonable arrangement of internal space and meeting the size requirements of existing household appliances.

[0052] According to the present application, the baffle assembly 52 is rotatably disposed on the diverter plate 32. In an exemplary embodiment, the diverter plate 32 is formed with a plurality of bosses that protrude relatively from the upper surface of the diverter plate 32, and the baffle assembly 52 is disposed on the plurality of bosses so as to be rotatable on the diverter plate 32.

[0053] In an embodiment, a plurality of through holes are provided on the baffle assembly 52, and the baffle assembly 52 is rotatably mounted on the diverter plate 32, and the upper surface of the baffle assembly 52 abuts against the bottom wall of the support plate 31, and the baffle assembly 52 rotates in a circumferential direction, so that the projection of the branch outlet 311 on the baffle assembly 52 overlaps with the corresponding through hole to connect the inlet 321 and the corresponding branch outlet 311.

[0054] In these embodiments, a plurality of through holes are provided on the baffle assembly 52 , and the plurality of through holes are selectively connected to the plurality of branch outlets 311 , thereby achieving diversion of the fluid entering the inner cavity of the diversion chamber 20 from the inlet 321 .

[0055] In an embodiment, the drive unit 51 includes a power source and a drive gear 511. The power source is a handwheel or a drive motor 512, and the drive gear 511 is connected to the output shaft of the power source. The baffle assembly 52 includes a first gear 521 and a second gear 522, each of which meshes with the drive gear 511 and is capable of receiving the rotational drive force of the drive gear 511. The through holes include a first through hole 5211 and a second through hole 5221, which are respectively disposed on the first gear 521 and the second gear 522. When the first gear 521 stops meshing with the drive gear 511, the first through hole 5211 is in communication with the corresponding branch outlet 311, while the second through hole 5221 is blocked from the corresponding branch outlet 311. When the first gear 521 and the second gear 522 stop meshing with the drive gear 511, the first through hole 5211 and the second through hole 5221 are respectively in communication with the corresponding branch outlet 311.

[0056] According to the present application, the first gear 521 and the second gear 522 may have teeth on both the circumferential outer edges, or may have teeth in a local area. Figure 7 and Figure 8As shown, multiple bosses include a first boss 3221 and a second boss 3222, the first gear 521 is rotatably set on the first boss 3221, the second gear 522 is rotatably set on the second boss 3222, and local areas of the outer edges of the first gear 521 and the second gear 522 have teeth, and the driving gear 511 is set between the first gear 521 and the second gear 522, and respectively engages with the corresponding teeth on the first gear 521 and the second gear 522.

[0057] According to the present application, the driving motor can rotate forward or reverse, thereby driving the baffle assembly 52 to rotate, so that the multiple through holes are connected or disconnected with the corresponding branch outlets 311 to meet various needs during use.

[0058] In an embodiment, the cleaning device further includes a guide assembly 60, which is disposed in the inner cavity of the diverter chamber 30, guiding the first gear 521 and the second gear 522 to rotate in the circumferential direction and limiting the range of rotation of the first gear 521 and the second gear 522 in the circumferential direction. In an exemplary embodiment, the guide assembly 60 includes a guide groove formed on one of the diverter plate 32 and the support plate 31, and a guide post formed on the other of the diverter plate 32 and the baffle assembly 52, and the guide post fits in the guide groove. It should be noted that when the guide groove is formed on the baffle assembly 52, the guide groove does not penetrate the upper surface of the baffle assembly 52. Figures 8 to 10 The guide groove is clearly shown on the upper surface of the corresponding baffle assembly 52 only for the convenience of understanding the structural features.

[0059] like Figure 7 and Figure 8 As shown, the guide column includes a first guide column 61 and a second guide column 62, and the first guide column 61 and the second guide column 61 are both formed on the diverter plate 32 and have a predetermined interval. The guide groove includes a first guide groove 63 and a second guide groove 64, and the first guide groove 63 and the second guide groove 64 are respectively formed on the first gear 521 and the second gear 522. Among them, the first gear 521 can rotate around the first guide column 61 within a preset range, and the second gear 522 can rotate around the second guide column 62 within a preset range, so that when it rotates to a range without teeth, it can avoid the influence of inertia on the movement of the baffle assembly 52 (for example, but not limited to, the failure of the gear meshing effect caused by not stopping when it needs to stop due to inertia). As an example, there are two branch outlets. When in use, as Figure 8 As shown, the driving gear 511 rotates clockwise by a first angle, and the first gear 521 and the second gear 522 respectively rotate by a first preset angle. At this time, the first through hole 5211 of the first gear 521 is connected to one branch outlet 311, and the second through hole 5221 of the second gear 522 is blocked from the other branch outlet 311, as shown in FIG. Figure 9As shown. The driving gear 511 continues to rotate clockwise, and the first gear 521 will not rotate along with the driving gear 511 because it is limited by the first guide post 61 and has rotated to the edge of the teeth on it. The second gear 522 will then rotate along with the second preset angle, so that the second through hole 5221 of the second gear 522 is connected to the corresponding branch outlet 311. At this time, as shown Figure 10 As shown, the first through hole 5211 of the first gear 521 and the second through hole 5221 of the second gear 522 are each in communication with the corresponding branch outlet 311. When the second gear 522 rotates until the second through hole 5221 is in communication with the corresponding branch outlet 311, the second gear 522 is restrained by the second guide post 62 and prevents it from disengaging due to inertia. Reversely driving the drive gear 511, i.e., rotating it counterclockwise, restores the branch outlet 311 to its blocked state.

[0060] In these embodiments, by limiting the range of rotation of the first gear 521 and the second gear 522 in the circumferential direction, the effective operation of the diverter assembly can be ensured, and the loss of diversion function due to deviation from the operating trajectory can be avoided.

[0061] According to the present application, the washing area 20 of the cleaning device can be set according to actual conditions. For example, but not limited to, the washing area 20 can be divided into a fixed washing area 21 and a candidate washing area 22. The channels corresponding to the fixed washing area 21 do not need to be controlled by the diverter component, while the channels corresponding to the candidate washing area 22 can be selectively controlled by the diverter component. Thus, by adding corresponding buttons to the user selection interface, the user can select different cleaning modes based on the cleaning volume. When the cleaning volume is small, the fixed washing area 21 can be selected for washing, making the diverter component a backup solution, which not only meets the original intention of saving energy but also ensures the service life of the diverter component.

[0062] like Figure 12 As shown, the diversion chamber 30 further has a fixed outlet 312. The washing area 20 includes a fixed washing area 21 and candidate washing areas 22. The candidate washing areas 22 include a first candidate washing area 221 and a second candidate washing area 222. The inlet of the nozzle 41 corresponding to the fixed washing area 21 is connected to the fixed outlet 312, and the inlet of the nozzle 41 corresponding to the candidate washing area 20 is selectively connected to the multiple branch outlets 311.

[0063] In these embodiments, by setting multiple modes, not only can the original intention of saving energy be met, but the service life of the diversion component can also be guaranteed.

[0064] In the embodiment, the cleaning apparatus further includes a support plate 70 disposed within the diverter chamber 30 and fixedly connected to the diverter plate 32. The upper surface of the support plate 70 abuts against the support plate 31. A conductive opening 71 extending vertically through the support plate 70 allows communication between the inlet 321 and the fixed outlet 312. Specifically, the diverter assembly and the support plate 70 are spaced apart within the diverter chamber 30. Specifically, the support plate 70 is fixedly connected to the diverter plate 32 via connecting posts 3223.

[0065] In these embodiments, by providing a support plate 70, the support plate 70 can be supported in the diversion chamber 30, thereby ensuring the stability of the diversion chamber 30 formed by the support plate 31 and the diversion plate 32 during use, and further ensuring the alignment accuracy of the inlet 321 and the branch outlet 311 during long-term use.

[0066] According to the present application, the spray arm 40 includes a body portion 42 and a plurality of nozzles 41 branchedly connected above the body portion 42, and an inlet 421 of each nozzle 41 is connected to a discharge port. Figure 11 As shown, the plurality of nozzles 41 are divided into fixed nozzles and candidate nozzles. The inlet 421 of the candidate nozzle is communicated with the corresponding branch outlet 311 , and the inlet 421 of the fixed nozzle is communicated with the fixed outlet 312 .

[0067] In an embodiment, the cleaning device further includes an air inlet channel 80 and a water inlet channel 90, and both the air inlet channel and the water inlet channel 90 can be connected to the inlet 321. Specifically, the cleaning device further includes a hot air component 100, which is arranged on the outer wall of the washing chamber 10 and is connected to the air inlet 82 of the air inlet duct 80, and the air outlet 81 of the air inlet duct 80 is connected to the inlet 321. The cleaning device further includes a pump component 110 and a water inlet, and the pump component 110 is connected between the water inlet connection port and the water inlet channel 90, and is used to pump the water input from the water inlet connection port into the water inlet channel 90, and transport it to the inlet 321 through the water outlet 91 of the water inlet channel 90. As Figure 1 、 Figure 2 、 Figure 14 and Figure 15 As shown, water flows from the water outlet of the pump assembly 110 into the water outlet 91 of the water inlet channel 90 and is transported to the inlet 321. The air flow blows from the hot air assembly 100 to the air inlet duct 80 and enters the inlet 321 through the air outlet 81 of the air inlet duct 80.

[0068] like Figure 13As shown, the cleaning device also includes an operation panel 130, which is arranged on the surface of the cleaning device, and the operation panel 130 has a corresponding washing area mark. The cleaning device also includes a controller 120 connected to a drive motor and a corresponding washing area mark. The washing area mark corresponds to the washing area. The controller is arranged inside the cleaning device, and is used to control the rotation direction of the drive motor, thereby controlling the rotation of the baffle assembly 52, and then realizing the conduction or isolation of the inlet 321 and the branch outlet 311. During use, the user can select the corresponding washing area mark according to the cleaning amount, and the controller controls the diversion assembly corresponding to the selected washing area, thereby connecting the inlet 321 and the branch outlet 311 corresponding to the selected washing area 20, and then the corresponding nozzle starts to spray water toward the selected washing area to perform cleaning work.

[0069] According to a second aspect of the present application, a control method is provided, which is applied to the cleaning equipment provided in each of the above embodiments, including:

[0070] Step S101, obtaining the target washing area 20 selected by the user.

[0071] In step S102, based on the target washing area 20, the diversion component is controlled to connect the inlet 321 and the branch outlet 311 corresponding to the target washing area 20.

[0072] In the embodiment of the present application, the target washing area 20 refers to the washing area selected by the user. The user can select the corresponding washing area according to the cleaning amount, and control the diversion component to connect the inlet 321 and the branch outlet 311 corresponding to the selected washing area 20.

[0073] In the embodiment, the cleaning device is a dishwasher. When the dishwasher is required to work, after the user opens the operating door of the dishwasher, the dishes can be placed in the washing area 20 of the washing chamber 10 according to the number of dishes. If the number of dishes is small and only one washing area 20 is needed to fully place them, the user can place the dishes in the fixed washing area 21 and then close the operating door. At this time, the status of each component in the diversion chamber 30 is as follows. Figure 8As shown, the conducting port 71 on the support plate 70 is connected to the fixed outlet 312. When the dishwasher begins washing, the pump assembly 110 pumps water, which passes sequentially through the water outlet 91 of the water inlet channel 90, the inlet 321, and then through the conducting port 71 and the fixed outlet 312. The water is then sprayed from the discharge port of the nozzle 41 on the spray arm 40 toward the fixed washing area 21 to wash the dishes in the fixed washing area 21. When drying the dishes, the hot air assembly 100 is activated. The air blown in by the hot air assembly 100 passes through the air outlet 81 of the air inlet channel 80, enters the inlet 321, and then passes through the conducting port 71 and the fixed outlet 312. The air is then blown from the discharge port of the corresponding nozzle 41 on the spray arm 40 toward the fixed washing area 21 to focus on drying the dishes in the fixed washing area 21. The direction of the wash water after entering the inlet 321 is consistent with the direction of the hot air.

[0074] When the dishes to be washed by the user need to be placed in two washing areas, the user needs to place the dishes in the first candidate washing area 221 and the fixed washing area 21 in the washing area 20 respectively, close the operating door, and then select the buttons corresponding to the first candidate washing area 221 and the fixed washing area 21 on the operating panel. At this time, the driving motor 512 is turned on and drives the driving gear 511 to rotate, so that the first gear 521 and the second gear 522 will also rotate with the driving gear 511. When the first gear 521 and the second gear 522 rotate to a certain angle A, the driving motor 512 stops rotating. At this time, the status of each component in the diversion chamber 30 is as follows: Figure 9 As shown, the conducting port 71 on the support plate 70 is connected to the fixed outlet 312, the first through-hole 5211 on the first gear 521 is connected to the corresponding branch outlet 311, and the second through-hole 5221 on the second gear 522 is blocked from the corresponding branch outlet 311. As described above, the washing water during washing and the air during drying flow through the nozzles corresponding to the first candidate washing area 221 and the fixed washing area 21, respectively, and act on the corresponding areas to wash and dry the dishes.

[0075] When the dishes to be washed by the user need to be placed in three washing areas, the user needs to place the dishes in the first candidate washing area 221, the second candidate washing area 222 and the fixed washing area 21 in the washing area 20, and close the operating door. Then select the buttons corresponding to the first candidate washing area 221, the second candidate washing area 222 and the fixed washing area 21 on the operating panel. At this time, the driving motor 512 is turned on and drives the first gear 521 and the second gear 522 to rotate angle B respectively. Since the first gear 521 can no longer follow the rotation, when the driving motor 512 continues to rotate, the driving motor 512 will only drive the second gear 522 to rotate angle C. At this time, the status of each component in the diversion chamber 30 is as follows. Figure 10As shown, the first through hole 5211 and the second through hole 5221 are connected to the corresponding branch outlet 311, and the conducting port 71 on the support plate 70 is connected to the fixed outlet 312. As described above, the washing water during washing and the air during drying flow into the corresponding washing area 20 through the nozzles corresponding to the washing area 20 and act on the corresponding area, thereby washing and drying the dishes.

[0076] It should be noted that the diversion components of the present application can be set into multiple groups, so as to divide the washing area into multiple candidate washing areas so as to be able to match them according to the user's cleaning volume.

[0077] The above are merely embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
