[0063] Example 1

[0064] Currently, dishwashers on the market usually have only one washing cavity. When users use them, no matter how many pieces of dishes they wash at a time under the same washing mode, the same amount of water and electricity will be consumed, which greatly leads to energy waste.

[0065] To this end, this embodiment provides a washing component.

[0066] In one embodiment, Figures 1 to 10 As shown, the washing range of the washing assembly covers at least two separated washing areas, and the washing assembly includes a spray arm support 2, a spray arm assembly 3 and a water distribution structure 4.

[0067] Among them, the spray arm support 2 is provided with spray arm fixing ports corresponding to the number of the washing areas; the spray arm assembly 3 is installed on the spray arm support 2, and the spray arm assembly 3 includes spray arms corresponding one-to-one to the washing areas, and the bottom of the spray arm assembly 3 is provided with spray arm ports connected one-to-one with the spray arms, and the spray arm ports are connected one-to-one with the spray arm fixing ports; the water diversion structure 4 is installed on the spray arm support 2, and a closed space is formed between the water diversion structure 4 and the spray arm support 2, and the water diversion structure 4 is provided with a fluid inlet 400 and through holes corresponding one-to-one to the spray arm fixing ports, the fluid inlet 400 is fluidically connected to the closed space, and the closed space is fluidically connected to each of the through holes, and the water diversion structure 4 can enable different numbers of through holes to be connected to the corresponding spray arm fixing ports.

[0068] In this embodiment, after water enters the enclosed space formed by the water diversion structure 4 and the spray arm support 2 through the fluid inlet 400, when the through-holes in the water diversion structure 4 connect to the spray arm fixed ports, the water can pass through the through-holes into the spray arm fixed ports and then be sprayed out of the corresponding spray arms for washing. The arrangement of the water diversion structure 4 allows different numbers of through-holes to connect to corresponding spray arm fixed ports, and different spray arm fixed ports connect to different spray arms, corresponding to different washing areas, thus enabling zoned washing based on the actual placement of dishes.

[0069] Specifically in one embodiment, the spray arm assembly 3 is installed on the spray arm support 2 , and the water diversion structure 4 is installed at the bottom of the spray arm support 2 .

[0070] In a preferred embodiment, the fluid inlet 400 can be used for both water intake and air intake. The water intake can be used for washing, and the air intake can be used for drying the washing area.

[0071] Based on the above embodiment, in a preferred embodiment, there are three washing areas, namely the first washing area 101, the second washing area 102, and the third washing area 103. Correspondingly, the spray arms are respectively the first spray arm 301, the second spray arm 302, and the third spray arm 303. The spray arm openings are respectively the first spray arm opening 304 connected to the first spray arm 301, the second spray arm opening 305 connected to the second spray arm 302, and the third spray arm opening 306 connected to the third spray arm 303. The spray arm fixed openings are respectively the first spray arm fixed opening 201 connected to the first spray arm opening 304, the second spray arm fixed opening 202 connected to the second spray arm opening 305, and the third spray arm fixed opening 203 connected to the third spray arm opening 306. The water diversion structure 4 includes a water diversion tray 401 and a drive structure 5. The closed space is formed between the water diversion plate 401 and the spray arm support 2, and the water diversion plate 401 is provided with a disc 402, a driving gear 403, a first gear 404 and a second gear 405 respectively meshing with the driving gear 403, the first gear 404 and the second gear 405 are both incomplete gears and the number of teeth of the first gear 404 is less than the number of teeth of the second gear 405, and there are three through holes, namely a first through hole 4021 provided on the disc 402, a second through hole 4041 eccentrically provided on the first gear 404, and a third through hole 4051 eccentrically provided on the second gear 405, the first through hole 4021 remains in communication with the first spray arm fixing port 201, and the second through hole 4051 is in communication with the first spray arm fixing port 201. When the teeth on the first side of a gear 404 are engaged with the driving gear 403, the second through hole 4041 is not connected to the second spray arm fixing port 202; when the teeth on the second side of the first gear 404 just leave the driving gear 403, the second through hole 4041 is connected to the second spray arm fixing port 202; when the teeth on the first side of the second gear 405 are engaged with the driving gear 403, the third through hole 4051 is not connected to the third spray arm fixing port 203; when the teeth on the second side of the second gear 405 are engaged with the driving gear 403, the third through hole 4051 is connected to the third spray arm fixing port 203; the driving structure 5 is connected to the driving gear 403 for driving the driving gear 403 to rotate.

[0072] In this embodiment, if Figures 7 to 10 As shown, the first through hole 4021 is always connected to the first spray arm fixing port 201, that is, during the washing operation, the first spray arm 301 can always wash the first washing area 101. The user's default order of placing dishes is the first washing area 101, the second washing area 102, and the third washing area 103. When the user only places dishes in the first washing area 101, the driving structure 5 does not work; Figure 9As shown, when the user places tableware in the first washing area 101 and the second washing area 102 at the same time, the driving structure 5 works to drive the driving gear 403 to rotate in the first direction (for example, clockwise) until the teeth on the second side of the first gear 404 just leave the driving gear 403. At this time, the second through hole 4041 is connected to the second spray arm fixing port 202, and the third through hole 4051 is not connected to the third spray arm fixing port 203. Then, the washing work can be started, and the first washing area 101 and the second washing area 102 are washed at the same time; Figure 10 As shown, when the user places tableware in the first washing area 101, the second washing area 102 and the third washing area 103 at the same time, the driving structure 5 works to drive the driving gear 403 to rotate in the first direction. After the teeth on the second side of the first gear 404 leave the driving gear 403, the driving gear 403 continues to rotate. At this time, the second through hole 4041 is connected with the second spray arm fixing port 202 and the first gear 404 no longer rotates. Until the teeth on the second side of the second gear 405 engage with the driving gear 403, the driving structure 5 stops working. At this time, the third through hole 4051 is connected with the third spray arm fixing port 203, and then the washing work can be started, and the first washing area 101, the second washing area 102 and the third washing area 103 are washed at the same time.

[0073] Specifically in one embodiment, the driving structure 5 is a motor, and the output shaft of the motor is connected to the driving gear 403. In an alternative embodiment, the driving structure 5 may include a motor and a transmission structure provided between the motor and the driving gear 403.

[0074] In a preferred embodiment, the washing chamber 1 is connected to a main control panel 6 and an operating panel 7 , and the motor and the operating panel 7 are both controlled by the main control panel 6 .

[0075] Based on the above embodiment, in a preferred embodiment, the central angle corresponding to the teeth on the second gear 405 is twice the central angle corresponding to the teeth on the first gear 404. In this embodiment, it is easier to control the rotation angle of the driving gear 403 driven by the driving structure 5.

[0076] On the basis of the above embodiment, in a preferred embodiment, a first limiting structure is provided between the first gear 404 and the water-dividing plate 401, and the first limiting structure is used to prevent the teeth on the second side of the first gear 404 from continuing to rotate after leaving the driving gear 403; and / or, a second limiting structure is provided between the second gear 405 and the water-dividing plate 401, and the second limiting structure is used to prevent the second gear 405 from disengaging from the driving gear 403. In this embodiment, the first limiting structure can ensure that the first gear 404 does not rotate excessively, so that when the driving gear 403 rotates counterclockwise, it can mesh with the first gear 404 again, and the second limiting structure can ensure that the second gear 405 is always in contact with the driving gear.

[0077] Wheel 403 is engaged.

[0078] Based on the above embodiment, in a preferred embodiment, the first limiting structure includes a first curved guide rail 4042 provided on the first gear 404 and a first limiting post 406 provided on the water diversion plate 401. The central angle corresponding to the first curved guide rail 4042 coincides with the central angle corresponding to the teeth on the first gear 404, and the first limiting post 406 is disposed within the first curved guide rail 4042. In this embodiment, the first limiting post 406 prevents the teeth on the second side of the first gear 404 from continuing to rotate after leaving the driving gear 403. In an alternative embodiment, the first limiting post 406 may be disposed on the first gear 404, and the first curved guide rail 4042 may be disposed on the water diversion plate 401.

[0079] Based on the above embodiment, in a preferred embodiment, the second limiting structure includes a second arcuate guide rail 4052 provided on the second gear 405 and a second limiting post 407 provided on the water diversion plate 401. The central angle corresponding to the second arcuate guide rail 4052 coincides with the central angle corresponding to the teeth on the second gear 405, and the second limiting post 407 is disposed within the second arcuate guide rail 4052. In this embodiment, the second limiting post 407 prevents the second gear 405 from disengaging from the driving gear 403 during rotation, ensuring that the second gear 405 remains engaged with the driving gear 403. In an alternative embodiment, the second limiting post 407 may be disposed on the second gear 405, and the second arcuate guide rail 4052 may be disposed on the water diversion plate 401.

[0080] Based on the above embodiment, in a preferred embodiment, each of the spray arm openings is plugged into the spray arm fixing opening. In this embodiment, the connection between the spray arm opening and the spray arm fixing opening is simple, and each through hole can be directly connected to the spray arm opening.

[0081] Example 2

[0082] This embodiment provides a dishwasher, comprising a washing chamber 1 and the washing assembly provided in the above embodiment, wherein at least two washing areas are separated in the washing chamber 1, and the washing assembly comprises at least two spray arms corresponding to the at least two washing areas.

[0083] My plan number

[0084] Example 3

[0085] This embodiment provides a washing control method, which is applied to the washing assembly or dishwasher provided in the above embodiments.

[0086] In one embodiment, the control method comprises the following steps:

[0087] S1. Obtain the number of selected washing areas N. Specifically, the number of washing areas can be selected by the user or obtained through an image sensor. Specifically, the number of washing areas can be 1, 2, or 3.

[0088] S2. Determine the number of through-holes in the water-dividing structure that communicate with the corresponding spray-arm fixed ports based on the selected number of washing zones N. Specifically, when the number of washing zones is 1, the number of through-holes in the water-dividing structure that communicate with the corresponding spray-arm fixed ports is controlled to be 1; when the number of washing zones is 2, the number of through-holes in the water-dividing structure that communicate with the corresponding spray-arm fixed ports is controlled to be 2; and when the number of washing zones is 3, the number of through-holes in the water-dividing structure that communicate with the corresponding spray-arm fixed ports is controlled to be 3. This allows for zoned washing based on the actual placement of dishes.

[0089] In one embodiment, the above step S2 specifically includes:

[0090] The operating angle of the driving gear driven by the driving structure is determined according to the difference h between the selected number of washing areas N and the initial default number of areas 1.

[0091] Specifically, when h is 0, the drive structure does not operate. When h is 0, it indicates that the number of selected washing areas N is 1, and only the first washing area is filled with dishes. In this case, the drive structure does not need to operate, the first through hole is connected to the first spray arm fixed port, and the first spray arm can spray water to wash the first washing area.

[0092] When h is 1, the angle A through which the driving structure drives the active gear to rotate in the first direction is 1. When h is 1, indicating that the number of selected washing zones N is 2, and the user places dishes in both the first and second washing zones, the driving structure operates, driving the active gear to rotate in the first direction (e.g., clockwise) until the teeth on the second side of the first gear just clear the active gear. At this point, the second through-hole connects to the second spray arm fixing port, while the third through-hole disconnects from the third spray arm fixing port. Washing can then begin. Angle A corresponds to the angle the active gear rotates from the moment the first gear's outermost teeth on the first side engage with the active gear until the moment the outermost teeth on the second side just clear the active gear.

[0093] When h is 2, the angle at which the driving structure drives the active gear to rotate in the first direction is A+B. When h is 2, it means that the number of selected washing areas N is 3, and the user places dishes in the first washing area, the second washing area, and the third washing area at the same time. The driving structure works, driving the active gear to rotate in the first direction. After the teeth on the second side of the first gear engage with the active gear, the active gear continues to rotate. At this time, the second through hole is connected to the second spray arm fixing port and the first gear no longer rotates. Until the teeth on the second side of the second gear engage with the active gear, the driving structure stops working. At this time, the third through hole is connected to the third spray arm fixing port, and then washing can begin. Angle B corresponds to the rotation angle when the active gear continues to rotate after the teeth on the second side of the first gear leave the active gear until the teeth on the second side of the second gear engage with the active gear.

[0094] Based on the above embodiment, in a preferred embodiment, the control method further includes:

[0095] S3. During the next wash cycle, the drive mechanism's rotational direction is determined based on the difference r between the number of wash zones M selected by the user and the number of wash zones N used during the previous wash cycle. The active gear's rotational angle is then controlled accordingly. Specifically, the program ends immediately after the previous wash cycle. During the next wash cycle, the drive mechanism does not need to be restored to its initial state. Instead, the drive mechanism's movement is controlled based on the difference r between the number of wash zones M selected by the user and the number of wash zones N used during the previous wash cycle, simplifying the process and increasing energy efficiency.

[0096] Specifically in one embodiment, when A=B, the above step S3 specifically includes:

[0097] When r is 0, the drive structure does not work. When r is 0, it means that the number of washing areas next time is the same as the number of washing areas last time, so the drive structure does not need to work and washing can start directly.

[0098] When r is -1, the drive mechanism rotates the driving gear in the second direction by an angle A, which is opposite to the first direction. When r is -1, the number of wash zones is one less than the number of zones in the previous wash. Therefore, washing can begin simply by controlling the drive mechanism to rotate the driving gear in the opposite direction by an angle A.

[0099] My plan number

[0100] When r is 1, the driving structure drives the driving gear to rotate in the first direction by an angle of A. When r is 1, it means that the number of washing areas next time is 1 more than the number of washing areas last time, so washing can start by simply controlling the driving structure to drive the driving gear to rotate in the first direction by an angle of A.

[0101] When r is -2, the drive mechanism drives the driving gear to rotate in the second direction by an angle of 2A. When r is -2, it means that the number of wash zones in the next wash is 2 less than the number of wash zones in the previous wash. Therefore, washing can begin by simply controlling the drive mechanism to drive the driving gear to rotate in the opposite direction by an angle of 2A. At this time, only the first wash zone can be washed.

[0102] When r is 2, the driving mechanism drives the driving gear to rotate in the first direction by an angle of 2A. When r is 2, it means that the number of washing zones in the next wash is 2 more than the number of washing zones in the previous wash. Therefore, washing can start by simply controlling the driving mechanism to drive the driving gear to rotate in the first direction by an angle of 2A. At this time, washing can be carried out in the first, second, and third wash zones.

[0103] In an alternative embodiment, when A and B are not equal, the above step S3 specifically includes:

[0104] When r is 0, the drive structure does not work. When r is 0, it means that the number of washing areas next time is the same as the number of washing areas last time, so the drive structure does not need to work and washing can start directly.

[0105] When r is -1, the difference i between the number of wash zones M selected by the user and 1 is determined. When i = 0, the drive structure drives the active gear to rotate in the second direction by an angle A. When i = 1, the drive structure drives the active gear to rotate in the second direction by an angle B. The second direction is opposite to the first direction. When r is -1, it indicates that the number of wash zones in the next wash is 1 less than the number of wash zones in the previous wash. There are two possible situations. When the number of wash zones M selected by the user is 1, that is, i = 0, the number of wash zones in the previous wash was 2. In this case, the drive structure needs to be controlled to rotate the active gear in the second direction by an angle A to start washing. When the number of wash zones M selected by the user is 2, that is, i = 1, the number of wash zones in the previous wash was 3. In this case, the drive structure needs to be controlled to rotate the active gear in the second direction by an angle B to start washing.

[0106] When r is 1, the difference i between the number of washing areas N and 1 is determined. When i=0, the driving structure drives the active gear to rotate in the first direction by an angle of A. When i=1, the driving structure drives the active gear to rotate in the first direction by an angle of A.

[0107] The angle at which the driving gear is driven by the wheel driving structure to rotate in the first direction is B. When r is 1, it means that the number of washing zones next time is one more than the number of washing zones last time. There are two situations: when the number of washing zones N selected by the user last time is 1, that is, i = 0, the number of washing zones next time is 2. At this time, the driving structure drives the driving gear to rotate in the first direction by angle A to start washing. When the number of washing zones N selected by the user last time is 2, that is, i = 1, the number of washing zones next time is 3. At this time, the driving structure drives the driving gear to rotate in the first direction by angle B to start washing.

[0108] When r is -2, the driving mechanism drives the driving gear to rotate in the second direction by an angle of A + B. When r is -2, it means the number of wash zones next time is 2 less than the number of wash zones last time, meaning the number of wash zones last time was 3 and the number of wash zones next time is 1. Washing can then begin after the driving mechanism drives the driving gear to rotate in the second direction by an angle of A + B.

[0109] When r is 2, the driving mechanism drives the driving gear to rotate in the first direction by an angle of A + B. When r is 2, it means that the number of washing zones next time is 2 more than the number of washing zones last time, that is, the number of washing zones last time was 1 and the number of washing zones next time is 3. At this time, the driving mechanism drives the driving gear to rotate in the first direction by an angle of A + B before washing can begin.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
