It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims.

[0102] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0103] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0104] This application provides a control method for a cleaning machine, specifically a dishwasher, used to clean tableware, kitchen utensils, and other items. Tableware may include bowls, plates, dishes, chopsticks, etc., and kitchen utensils may include pots, pans, etc. In addition, the cleaning machine can also be used to clean items of the same or similar size and structure as the tableware and kitchen utensils. In the embodiments described in this specification, a dishwasher is mainly used as an example. Other similar application scenarios can be found in this specification, and will not be detailed here.

[0105] Please refer to the following: Figures 1 to 3 The cleaning machine may include a spray device 100 and a drive device 300. The spray device 100 is used to spray tableware and / or kitchenware, and the drive device 300 is used to provide rotational power for the tableware and / or kitchenware. The spray device 100 has at least a first spray state and a second spray state for spraying and cleaning tableware and / or kitchenware, wherein the first spray state is different from the second spray state.

[0106] The control method of the cleaning machine may include: controlling the spray device 100 to spray, and controlling the drive device 300 to operate at least once during the switching process between the first spray state and the second spray state. Preferably, in order to ensure comprehensive cleaning, the drive device 300 can be controlled to operate each time during the switching process between the first spray state and the second spray state.

[0107] The cleaning machine is equipped with a spray device 100, which can be used to spray and clean tableware and / or kitchenware. When the spray device 100 is working, it is connected to a liquid supply system to provide cleaning liquid to the tableware and / or kitchenware. The liquid supply system can be a system capable of supplying spray liquid to the spray device 100. Specifically, the liquid supply system can be a tap water source to provide room temperature water to the nozzle device; the liquid supply system can also be equipped with a heating device to heat the room temperature water, thereby providing hot water to the spray device 100; in addition, the liquid supply system can also include a container for holding detergent with degreasing function, thereby providing detergent to the spray device 100, or providing a mixture of detergent and water to the spray device 100. Furthermore, the liquid supply system of the cleaning machine can be superimposed with other functional modules, such as a water softening module, to provide water softened by the water softening module to the spray device 100.

[0108] When in operation, the spray device 100 can be positioned at one or more designated locations to spray tableware and kitchen utensils in a directional manner; alternatively, the spray device 100 can be in a rotating state to spray tableware and kitchen utensils in a rotating manner, or a combination of the above-mentioned spray states. When the spray device 100 is in a rotating state while spraying and cleaning the tableware and / or kitchen utensils, its rotational power can be hydraulic, electric, magnetic, or a combination of two or more driving forces, or it can also combine other forms of driving.

[0109] Specifically, the spraying device 100 may include at least one spraying arm with nozzles. Of course, the spraying device 100 may also include other structures or other forms, but this application does not make specific limitations here.

[0110] The different spraying states of the spraying device 100 can vary depending on the specific form, distribution location, and liquid discharge conditions of the spraying device 100. The spraying device 100 has at least two different spraying states.

[0111] The washing machine is equipped with a drive device 300, which provides rotational power to the tableware and / or kitchenware when they are located within the drive device 300. Specifically, when the tableware and / or kitchenware are located within the drive device 300, rotational power is provided based on the friction between the tableware and / or kitchenware and the drive device 300. For example, during rotation, the transmission component in the drive device 300 can generate significant static friction with the tableware and / or kitchenware, thereby driving the tableware and / or kitchenware to rotate. Of course, the specific method of using the drive device 300 to drive the tableware and / or kitchenware to rotate is not limited to the examples above; any implementation that can drive the tableware and / or kitchenware to rotate is covered within the scope defined by the claims of this invention. The power source of the drive device 300 can be electric, hydraulic, magnetic, or a combination of two or more driving forces, or other power driving methods or a combination of multiple power driving methods; this application does not specifically limit this.

[0112] When the cleaning machine is in operation, it switches between different spray states, for example, switching between a first spray state and a second spray state. The control method of the cleaning machine provided in this application utilizes the transition time period during the switching between different spray states to control the drive device 300 to operate, thereby driving the tableware and / or kitchenware to rotate. Compared to setting a separate working state for driving the tableware and / or kitchenware to rotate, utilizing the transition time period during the switching of spray states to drive the tableware and / or kitchenware to rotate improves cleaning efficiency and shortens cleaning time.

[0113] The following will provide a detailed explanation in conjunction with the accompanying drawings and different embodiments.

[0114] like Figure 1 As shown, in the first embodiment, the spraying device 100 includes a first spraying mechanism 110 and a second spraying mechanism 120. The first spraying state or the second spraying state includes any one of the following: only the first spraying mechanism 110 sprays; the first spraying mechanism 110 and the second spraying mechanism 120 spray simultaneously; only the second spraying mechanism 120 sprays.

[0115] In this embodiment, the spraying device 100 may include a first spraying mechanism 110 and a second spraying mechanism 120. Both the first spraying mechanism 110 and the second spraying mechanism 120 may be in the form of a spraying arm. Of course, the first spraying mechanism 110 or the second spraying mechanism 120 may also be in other forms, and this application does not make specific limitations here.

[0116] The spray device 100 includes a variety of different spray states. Specifically, the spray states may include: only the first spray mechanism 110 sprays water; only the second spray mechanism 120 sprays water; and the first spray mechanism 110 and the second spray mechanism 120 spray water simultaneously.

[0117] The switching process between the first spraying state and the second spraying state may specifically include any one of the following: a switching process from a spraying state in which only the first spraying mechanism 110 sprays to a spraying state in which both the first spraying mechanism 110 and the second spraying mechanism 120 spray simultaneously; a switching process from a spraying state in which both the first spraying mechanism 110 and the second spraying mechanism 120 spray simultaneously to a spraying state in which only the second spraying mechanism 120 sprays; a switching process from a spraying state in which only the second spraying mechanism 120 sprays to a spraying state in which both the first spraying mechanism 110 and the second spraying mechanism 120 spray simultaneously; a switching process from a spraying state in which both the first spraying mechanism 110 and the second spraying mechanism 120 spray simultaneously to a spraying state in which only the first spraying mechanism 110 sprays.

[0118] During a cleaning cycle, the state switching of the spray device 100 can be as follows:

[0119] First, spraying is performed only by the first spraying mechanism 110 in the first position;

[0120] Next, the process switches to: simultaneous spraying by the first spraying mechanism 110 in the first position and the second spraying mechanism 120 in the second position;

[0121] Then, the process is switched to: spraying is performed only by the second spraying mechanism 120 in the second position;

[0122] Next, the process switches to: simultaneous spraying by the first spraying mechanism 110 in the first position and the second spraying mechanism 120 in the second position;

[0123] Finally, switch back to: spraying is performed only by the first spraying mechanism 110 in the first position.

[0124] During any of the two spray states mentioned above, the drive device 300 can be controlled to rotate, thereby causing the sprayed tableware and / or kitchenware to rotate, making the spray device 100 rinse the tableware and / or kitchenware more evenly, and thus improving cleaning efficiency and cleaning effect.

[0125] Of course, considering the actual placement area of ​​tableware and / or kitchen utensils, the ease of cleaning, and other specific circumstances, this instruction manual does not preclude the possibility that the control drive device 300 may not operate during the switching between two spray states. For example, when the tableware and / or kitchen utensils corresponding to the second position are easier to clean, the spray state in which the first spray mechanism 110 in the first position and the second spray mechanism 120 in the second position spray simultaneously can be directly switched back to the spray state in which only the first spray mechanism 110 in the first position sprays.

[0126] In the second embodiment, the switching process between the first spraying state and the second spraying state specifically includes any one of the following: a switching process from a spraying state in which only the first spraying mechanism 110 sprays to a spraying state in which only the second spraying mechanism 120 sprays; or a switching process from a spraying state in which only the second spraying mechanism 120 sprays to a spraying state in which only the first spraying mechanism 110 sprays.

[0127] In this embodiment, the difference from the first embodiment described above is that the first spray mechanism 110 and the second spray mechanism 120 of the spray device 100 switch between each other and do not work simultaneously.

[0128] like Figure 2 As shown, in the third embodiment, the spraying device 100 may include a first spraying mechanism 110, a second spraying mechanism 120, and a third spraying mechanism 130. The first spraying state or the second spraying state includes any one of the following: only the first spraying mechanism 110 sprays; the first spraying mechanism 110 and the second spraying mechanism 120 spray simultaneously; only the second spraying mechanism 120 sprays; the second spraying mechanism 120 and the third spraying mechanism 130 spray simultaneously; only the third spraying mechanism 130 sprays; the third spraying mechanism 130 and the first spraying mechanism 110 spray simultaneously; the first spraying mechanism 110, the second spraying mechanism 120, and the third spraying mechanism 130 spray simultaneously.

[0129] The spray device 100 may include a first spray mechanism 110, a second spray mechanism 120, and a third spray mechanism 130. The first spray mechanism 110, the second spray mechanism 120, and the third spray mechanism 130 can all be in the form of spray arms. Of course, the first spray mechanism 110, the second spray mechanism 120, or the third spray mechanism 130 can also be in other forms, and this application does not impose specific limitations here. The first spray mechanism 110, the second spray mechanism 120, and the third spray mechanism 130 can be arranged in different height directions. For example, the first spray mechanism 110 can be located at the bottom, the third spray mechanism 130 can be located at the top, and the second spray mechanism 120 can be located in between. Of course, the specific positional relationship of the first spray mechanism 110, the second spray mechanism 120, and the third spray mechanism 130 is not limited to the above examples. It can be adaptively adjusted according to the internal structure of the washing machine, the arrangement of tableware and / or kitchen utensils, etc., and this application does not impose specific limitations here.

[0130] When the spray device 100 includes a first spray mechanism 110, a second spray mechanism 120 and a third spray mechanism 130, the spray states that can be formed include: water output from only one spray mechanism, water output from two spray mechanisms at the same time, or water output from all three spray mechanisms at the same time.

[0131] In this embodiment, the difference from the first embodiment described above is that the number of spray mechanisms in the spray device 100 is increased by one. When the number of spray mechanisms in the spray device 100 is three, its spraying state can be: water is output only from any one of the first spray mechanism 110, the second spray mechanism 120, and the third spray mechanism 130; water is output from any two of the first spray mechanism 110, the second spray mechanism 120, and the third spray mechanism 130; or water is output from all three spray mechanisms simultaneously. Specifically, there are various arrangements and combinations, which will not be listed in detail here.

[0132] In one embodiment, the start and stop times of the drive device 300 can be as follows:

[0133] During the switching process from the first spray state to the second spray state, the drive device 300 is controlled to operate when the first spray state ends or after it ends; and / or the drive device 300 is stopped before the second spray state begins.

[0134] In this embodiment, during the switching process from the first spray state to the second spray state, controlling the drive device 300 to operate at the end of the first spray state means that the first spray state has been completed when the tableware and / or kitchen utensils are being driven to rotate. At this time, when the driving force of the drive device 300 is hydraulic (i.e., the drive device 300 is a hydraulic drive device 300), and the spray device 100 and the drive device 300 are supplied with liquid by the same water pump 700, then when the drive device 300 is restarted at the end of the first spray state, there will be a certain pressure in the water circuit. This can increase the starting pressure of the drive device 300, ensuring that the tableware and / or kitchen utensils can be reliably driven to rotate under a higher starting pressure.

[0135] Furthermore, the drive device 300 can be stopped before the second spraying state begins. When the drive force of the drive device 300 is hydraulic, and the spraying device 100 and the drive device 300 are supplied with liquid by the same water pump 700, starting the second spraying state after the drive device 300 stops can also create a certain pressure in the pipeline, thereby increasing the hydraulic pressure of the spraying liquid output into the spraying device 100.

[0136] In another embodiment, the start and stop times of the drive device 300 can be as follows:

[0137] During the switching process from the first spray state to the second spray state, the drive device 300 is controlled to operate before the first spray state ends; and / or the drive device 300 is stopped after the second spray state begins.

[0138] In this embodiment, during the switching process from the first spray state to the second spray state, controlling the drive device 300 to operate before the first spray state ends means that the first spray state has not yet been completed when the tableware and / or kitchen utensils are being driven to rotate.

[0139] When the driving force of the drive device 300 is water power (i.e., the drive device 300 is a water-driven device), and the spray device 100 and the drive device 300 are supplied with liquid by the same water pump 700, the drive device 300 is started before the end of the first spray state. On the one hand, the water pump will not be blocked, which can ensure the reliability of the water pump; on the other hand, the process of using the drive device 300 to drive the tableware and / or kitchenware to rotate can make fuller use of the time with the previous spray state that has not ended, thereby ensuring that there is enough time to rotate the tableware and / or kitchenware without taking up extra cleaning time.

[0140] Furthermore, the drive device 300 can be stopped after the second spray state begins. That is, the tableware and / or kitchen utensils can still be rotated while switching to the second spray state. Similarly, when the drive force of the drive device 300 is hydraulic (i.e., the drive device 300 is a hydraulic drive device), and the spray device 100 and the drive device 300 are supplied with liquid by the same water pump 700, the drive device 300 is stopped after the second spray state begins. On the one hand, the water pump will not become blocked, ensuring its reliability; on the other hand, the process of using the drive device 300 to drive the tableware and / or kitchen utensils to rotate can make fuller use of the time of the next spray state that has already begun, thus ensuring sufficient time for the tableware and / or kitchen utensils to rotate without taking up extra cleaning time.

[0141] Furthermore, within a cleaning cycle, the switching process between the first spray state and the second spray state includes multiple steps, and the control method may further include: controlling the drive device 300 to operate during each switching process.

[0142] In this embodiment, a cleaning cycle may include multiple switching processes for different spray states. The number of times the control drive device 300 operates can be comprehensively determined based on factors such as the number of spray mechanisms in the spray device 100, the method of switching spray states, the correspondence between the spray mechanisms and tableware and / or kitchenware, and the different levels of difficulty in cleaning tableware and / or kitchenware in different areas. This application does not impose specific limitations here. For example, the drive device 300 can be controlled to operate during each switching process. For example, as... Figure 1 As shown, the spray device 100 includes a first spray mechanism 110 and a second spray mechanism 120. During each switching process, the drive device 300 can be controlled to rotate, thereby rotating the sprayed tableware and / or kitchen utensils, making the spray device 100 rinse the tableware and / or kitchen utensils more evenly, and improving cleaning efficiency and effect. Of course, during one or more switching processes, the drive device 300 can also be controlled not to operate according to actual cleaning needs.

[0143] Please refer to the following: Figures 1 to 3 This application also provides a cleaning machine, which may include: a spray device 100 and a drive device 300, wherein the spray device 100 is used to spray tableware and / or kitchenware, and the drive device 300 is used to provide rotational power to the tableware and / or kitchenware; the spray device 100 has at least a first spray state and a second spray state for spraying and cleaning tableware and / or kitchenware, wherein the first spray state is different from the second spray state; and a controller for executing the control method of the above-described cleaning machine.

[0144] The specific descriptions of the spraying device 100 and the driving device 300 can be found in the above embodiments, and will not be repeated here. The driving device 300 may include any one or a combination of the following: an electric driving device 300, a magnetic driving device 300, and a hydraulic driving device 300.

[0145] In this specification, the cleaning machine may also include a controller for performing the control method of the cleaning machine described above.

[0146] In addition to the aforementioned components, the cleaning machine may also include other supporting parts, such as a water cup 810, a water inlet solenoid valve 830, and a drain pump 840. The water cup 810 may be positioned below at least one of the spray device 100 and the drive device 300. During the entire operating cycle of the cleaning machine, the drain pump 840 may periodically activate a predetermined number of times to drain the water from the water cup 810. The water inlet solenoid valve 830 can be used to control the connection between the external water source and the cleaning machine.

[0147] When the cleaning machine is equipped with a water softening module, the water softening module can be located downstream of the inlet solenoid valve 830. When the inlet solenoid valve 830 is open, external water can enter the water softening module for softening treatment, and the softened water can then be supplied to the water cup 810. When the (washing) pump is turned on, the water in the water cup 810 can be pressurized by the pump and supplied to the spray device 100 and the drive device 300 through the pipeline. Of course, the cleaning machine may also include other functional modules or components, and this application does not specifically limit the specific components.

[0148] Furthermore, the cleaning machine may also include a switching device controlled by the controller, the switching device being used to switch the spraying state of the spraying device 100 and / or the state of the drive device 300. Specifically, the switching device can change the connection state between the liquid supply system and the spraying device 100 and the drive device 300, thereby changing the spraying state at different positions of the spraying device 100 and the state of the drive device 300.

[0149] In this specification, the spraying state of the spraying device 100 mainly refers to the different positions where the cleaning liquid is sprayed, but it is not limited to the examples mentioned above; it can also include differences in the speed and pressure of the sprayed cleaning liquid. The state of the driving device 300 mainly refers to whether the driving device 300 is activated, but it is not limited to the examples mentioned above. When the driving device 300 is activated, its state can also include differences in the operating parameters of the driving device 300 (e.g., the rotational speed at which the tableware / kitchenware rotates). Specifically, when the form of the switching device is different, the specific switching method is also different.

[0150] In one embodiment, the drive device 300 may include a hydraulic drive device, the spray device 100 includes a plurality of spray mechanisms, the switching device is intermittently connected to the drive device 300 and intermittently connected to one of the spray mechanisms or a combination of the spray mechanisms; and / or, the spray device 100 includes at least a first spray port 140 and a second spray port 150, the switching device is intermittently connected to the drive device 300 and intermittently connected to the first spray port 140 and / or the second spray port 150 of the spray device 100.

[0151] In this embodiment, when the drive device 300 is a hydraulic drive device, the switching device can be used to change the connection relationship of the water path, thereby changing the spraying state and controlling the operation of the drive device 300.

[0152] like Figure 1 or Figure 2 As shown, when the spray device 100 includes multiple spray mechanisms, the controller can control the connection sequence of the switching device with the drive device 300, different spray mechanisms or combinations thereof, so as to efficiently clean tableware and / or kitchen utensils.

[0153] In addition, such as Figure 3 As shown, when the spray device 100 includes a spray mechanism, the spray mechanism may include multiple spray nozzles, for example, it may include a first spray nozzle 140 and a second spray nozzle 150. The controller can control the connection sequence of the switching device with the drive device 300, different spray nozzles or combinations thereof, thereby efficiently cleaning tableware and / or kitchen utensils.

[0154] The switching device may include any one of the following: a single flow control device, or a combination of multiple flow control devices.

[0155] In this embodiment, the switching device may include one flow control device or a combination of multiple flow control devices. Specifically, the number of switching devices can be determined comprehensively based on the actual pipeline layout, the form of the flow control device itself, and other factors. For example, the flow control device may be a single water distribution valve 200, a combination of multiple solenoid valves, a combination of a water distribution valve 200 and a solenoid valve, or other feasible forms.

[0156] In the following embodiments, the switching device will be described in detail using the water distribution valve 200 as an example, with reference to the accompanying drawings.

[0157] Please refer to the following: Figures 4 to 19When the switching device includes only one flow control device, the switching device includes a water distribution valve 200. The water distribution valve 200 includes a valve body 210 and a water distribution plate 220 that is at least partially disposed in the valve body 210 and movable relative to the valve body 210. During the operation of the driving device 300, the water distribution plate 220 is in a continuous motion state or an intermittent motion state relative to the valve body 210.

[0158] In this embodiment, when there is only one flow control device, the switching device can be in the form of a water distribution valve 200. The water distribution valve 200 can include a valve body 210 and a water distribution plate 220 that is movable relative to the valve body 210. Specifically, when the cross-section of the inner cavity of the valve body 210 is circular, the water distribution plate 220 can rotate relative to the valve body 210. Specifically, the side of the valve body 210 away from its bottom is an open end, and the water distribution valve 200 also includes a sealing cap 230 for sealing the open end and a motor 240 for driving the water distribution plate 220 to rotate. After the motor 240 is powered on and started, the motor 240 drives the water distribution plate 220 to rotate relative to the valve body 210. Of course, the shape and structure of the valve body 210 are not limited to the above examples; the movement of the water distribution plate 220 relative to the valve body 210 can also be a movement, or a combination of rotation and movement, etc. In the embodiments described in this specification, the movement of the water divider 220 relative to the valve body 210 is mainly described by taking rotation as an example.

[0159] Specifically, during the operation of the drive device 300, when the water distributor 220 moves relative to the valve body 210 in a rotational manner, it can be in a continuous rotational state, for example, rotating at a constant speed; or, the water distributor 220 can be in an intermittent rotational state, for example, first rotating at a certain angle, then stopping for a period of time, and then repeating the alternating process of rotation and stopping. The specific motion mode of the water distributor 220 relative to the valve body 210 can be determined according to the specific application scenario, and this application does not make specific limitations here.

[0160] Specifically, the valve body 210 is provided with at least one inlet 201, at least one first outlet 211, and at least one second outlet 212. The water divider 220 is at least partially disposed within the valve body 210. During the movement of the water divider 220 relative to the valve body 210, the water divider 220 switches the connection state between the inlet 201 and the first outlet 211 and the second outlet 212.

[0161] The inlet 201 on the valve body 210 is used to introduce fluid from the supply system into the water distribution valve 200. The first outlet 211 and the second outlet 212 are used to guide the fluid in the water distribution valve 200 to the drive device 300 and / or the spray device 100. The positions of the inlet 201 and the outlet can be determined based on the shape and structure of the valve body 210 and the water distribution plate 220, as well as the relative fit between the valve body 210 and the water distribution plate 220. This application does not impose specific limitations on these aspects.

[0162] The water distribution valve 200 has multiple outlets. In order to make the structure of the water distribution valve 200 more compact and minimize the installation space required by the water distribution valve 200, the positions of the outlets can be arranged reasonably.

[0163] Specifically, the valve body 210 may include a bottom wall and a side wall surrounding the bottom wall, with the first outlet 211 disposed on the bottom wall and the second outlet 212 disposed on the side wall. When the first outlet 211 and the second outlet 212 are respectively disposed on the side wall and the bottom wall of the valve body 210, compared to the case where multiple outlets are disposed on the bottom wall or multiple outlets are disposed on the side wall, the side wall and the bottom wall of the valve body 210 are rationally utilized, and the overall size of the water distribution valve 200 is reduced.

[0164] The water divider 220 is rotatably disposed within the water divider valve 200. The water divider 220 may have connecting portions matching the number and position of its water outlets. Driven by the motor 240, the connecting portions on the water divider 220 connect one or more water outlets, thereby connecting different water paths. Specifically, the water divider 220 may include a bottom portion opposite to the bottom wall and a side portion opposite to the side wall. The bottom portion has a first connecting portion 221 that communicates with the first water outlet 211, and the side wall has a second connecting portion 222 that communicates with the second water outlet 212.

[0165] The bottom of the water divider 220 can be opposite to the bottom wall of the valve body 210. For example, the bottom of the water divider 220 can be a plate with a certain wall thickness, and a first connecting portion 221 is provided at the bottom. When the water divider 220 rotates relative to the valve body 210 to a certain position, the first connecting portion 221 is connected to the first outlet 211 on the bottom wall, and the fluid entering the water divider valve 200 from the inlet 201 flows out through the first connecting portion 221 and the first outlet 211. The side of the water divider 220 can have a notch structure, which can be used to form the second connecting portion 222 of the water divider 220. When the water divider 220 rotates relative to the valve body 210 to a certain position, the second connecting portion 222 is connected to the second outlet 212 on the side wall, and the fluid entering the water divider valve 200 from the inlet 201 flows out through the second connecting portion 222 and the second outlet 212.

[0166] Please see Figure 4 , Figure 5 and Figure 6 In a first embodiment of the water distribution valve 200, a first water outlet 211 is provided on the bottom wall and a second water outlet 212 is provided on the side wall; the first water outlet 211 is used to connect with the spray device 100 and the second water outlet 212 is used to connect with the drive device 300, or the first water outlet 211 is used to connect with the drive device 300 and the second water outlet 212 is used to connect with the spray device 100.

[0167] In this embodiment, the water distribution valve 200 can be provided with two water outlets: a first water outlet 211 located on the bottom wall and a second water outlet 212 located on the side wall. The first water outlet 211 is connected to the spray device 100, and the second water outlet 212 is connected to the drive device 300; alternatively, the first water outlet 211 is connected to the drive device 300, and the second water outlet 212 is connected to the spray device 100. That is, the connection relationship between the first water outlet 211, the second water outlet 212 and the spray device 100 and the drive device 300 is not specifically limited here, and can be selected based on the actual installation environment, ease of installation, etc.

[0168] For the second and third embodiments of the water distribution valve 200, please refer to the relevant documents. Figures 7 to 13 The valve body 210 is also provided with a third water outlet 213, which is located on the bottom wall or side wall. Two of the first water outlet 211, the second water outlet 212 and the third water outlet 213 are respectively used to connect to the spray device 100, and the other is used to connect to the drive device 300.

[0169] In this embodiment, the valve body 210 may also be provided with a third outlet 213, meaning the water distribution valve 200 may have three outlets. The third outlet 213 may be located on the bottom wall or the side wall of the valve body 210. Two of the first outlet 211, the second outlet 212, and the third outlet 213 are respectively connected to the spray device 100, and the other is connected to the drive device 300.

[0170] Please see Figure 7 , Figure 8 and Figure 9 In a second embodiment of the water distribution valve 200, the third outlet 213 may be located on the bottom wall, the first outlet 211 and the third outlet 213 are used to communicate with the spray device 100, and the second outlet 212 is used to communicate with the drive device 300.

[0171] Specifically, when the third outlet 213 is installed on the bottom wall, the first outlet 211 and the third outlet 213 installed on the bottom wall can be connected to the spray device 100 separately or simultaneously; the second outlet 212 can be connected to the drive device 300.

[0172] Alternatively, please see Figure 12 and Figure 13 In a third embodiment of the water distribution valve 200, the third outlet 213 may be located on the side wall, the second outlet 212 and the third outlet 213 are respectively used to connect with the spray device 100, and the first outlet 211 is used to connect with the drive device 300.

[0173] Overall, the principle and function of the third outlet 213 being set on the side wall are the same as those being set on the bottom wall, and the two can be replaced by each other.

[0174] Specifically, when the third outlet 213 is installed on the side wall, the first outlet 211 installed on the bottom wall can be connected to the drive device 300, and the second outlet 212 and the third outlet 213 installed on the side wall can be connected to the spray device 100 respectively or simultaneously.

[0175] When the valve body 210 is provided with a third water outlet 213, the water divider 220 can also be provided with a third connecting part 223, which can be connected to the water outlet on the valve body 210 for connecting the spray device 100.

[0176] Overall, the third connecting part 223 can be located at the bottom of the water divider 220 or at the side of the water divider 220. The position of the third connecting part 223 can match the position of the third outlet 213 on the valve body 210. For example, when the third outlet 213 is located on the side wall of the valve body 210, the third connecting part 223 can be located on the side of the water divider 220; when the third outlet 213 is located on the bottom wall of the valve body 210, the third connecting part 223 can be located at the bottom of the water divider 220.

[0177] like Figure 10 As shown, in the case where the third outlet 213 is located on the bottom wall of the valve body 210 and the third connecting part 223 is located at the bottom of the water divider 220, the first connecting part 221 and the third connecting part 223 can be a first opening and a second opening spaced apart at the bottom of the water divider 220. The first opening matches the shape of the outlet at the bottom of the valve body 210, and the second opening can be a waist hole.

[0178] When the second opening is a waist-shaped opening, it allows simultaneous connection to two different spray mechanisms or different spray nozzles on the same spray mechanism during a certain period of rotation of the water divider 220 relative to the valve body 210. Specifically, this waist-shaped opening can be an arc-shaped groove with a certain curvature formed on the water divider 220. During the rotation of the water divider 220 relative to the valve body 210, this waist-shaped opening can simultaneously connect to two water outlets. Theoretically, the longer the arc length of the arc groove, the longer the duration of simultaneous spraying by the two spray mechanisms. Specifically, the arc length of the arc groove can be determined according to the required duration of simultaneous spraying by the two spray arms; this application does not impose a specific limitation here.

[0179] Furthermore, the waist hole can be replaced with other forms, such as two non-connected openings, which can still achieve the function of the water divider 220 simultaneously connecting two spray mechanisms. When the valve body 210 is provided with a third outlet 213, the water divider 220 can also be provided with a third connecting part 223 and a fourth connecting part 224, which can be connected to the outlet of the valve body 210 for connecting the spray device 100.

[0180] Specifically, the third connecting part 223 and the fourth connecting part 224 are respectively disposed at the bottom and / or side of the water divider 220.

[0181] When the third connecting part 223 and the fourth connecting part 224 are spaced apart at the bottom, the positional relationship between the first connecting part 221, the third connecting part 223, the fourth connecting part 224 and the two water outlets for connecting the spray device 100 is configured such that, during the switching process from a position that connects only one of the water outlets for spraying to a position that connects only the other water outlet for spraying, there is a position where both water outlets for spraying are connected.

[0182] In this embodiment, when the third connecting portion 223 and the fourth connecting portion 224 are spaced apart at the bottom, the first connecting portion 221, the third connecting portion 223, and the fourth connecting portion 224 at the bottom are used to connect the two water outlets of the spray device 100. When the three connecting portions on the water divider 220 correspond to the two water outlets on the valve body 210, the water divider valve 200 can maintain a state where both water outlets for spraying are connected during the switching process from a position where only one water outlet for spraying is connected to a position where only the other water outlet for spraying is connected.

[0183] Please refer to the following: Figure 9 Specifically, the third connecting portion 223 and the fourth connecting portion 224 are spaced apart at the bottom. In one specific embodiment, the first connecting portion 221 is spaced 180° apart from the third connecting portion 223, the first outlet 211 and the third outlet 213 are spaced 180° apart, and the fourth connecting portion 224 is spaced 90° apart from both the first connecting portion 221 and the third connecting portion 223. The arrangement of the first connecting portion 221, the third connecting portion 223, and the fourth connecting portion 224 on the water divider 220, and the distribution of the first outlet 211 and the third outlet 213 on the valve body 210, reliably ensure that the water divider valve 200 can maintain a position where both outlets for spraying are connected during the switching process from a position where only one outlet for spraying is connected to a position where only the other outlet for spraying is connected.

[0184] Please refer to the following: Figure 11In the first position of the water divider 220, the first outlet 211 and the first connecting part 221 are connected, while the other outlets and connecting parts are not connected. At this time, the water divider valve 200 is only connected to the first spray mechanism 110. When the water divider 220 rotates a certain angle relative to the valve body 210, the second connecting part 222 of the water divider 220 is connected to the second outlet 212 of the valve body 210. At this time, the water divider valve 200 is connected to the drive device 300. When the water divider 220 rotates a certain angle relative to the valve body 210 again, the first connecting part 221 of the water divider 220 is connected to the third outlet 213, and the third connecting part 223 is connected to the first outlet 211. At this time, the water divider valve 200 is simultaneously connected to the first spray mechanism 110 and the second spray mechanism 120. After the water divider 220 rotates a certain angle relative to the valve body 210, the third connecting part 223 of the water divider 220 connects to the third water outlet 213. At this time, the water divider valve 200 is only connected to the second spray mechanism 120.

[0185] Of course, the structure of the water divider 220 simultaneously connecting the two outlets of the valve body 210 is not limited to the above example. Those skilled in the art can make other modifications based on the essence of the technical solution disclosed in this application. As long as the function is the same, they should all be covered within the scope of protection claimed in this application.

[0186] Similarly, when the third connecting part 223 and the fourth connecting part 224 are spaced apart on the side, the positional relationship between the second connecting part 222, the third connecting part 223, the fourth connecting part 224 and the two outlets for connecting the spray device 100 is configured such that, during the switching process from a position that connects only one of the outlets for spraying to a position that connects only the other outlet for spraying, there is a position where both outlets for spraying are connected.

[0187] In this embodiment, the main difference compared to the case where the three connecting parts for connecting the water outlet are located at the bottom is that the three connecting parts for connecting the water outlet are located on the side.

[0188] When the third connecting portion 223 and the fourth connecting portion 224 are spaced apart on the side, the second connecting portion 222, the third connecting portion 223, and the fourth connecting portion 224 on the side are used to connect the two outlets of the spray device 100. Similarly, when the three connecting portions on the water divider 220 correspond to the two outlets on the valve body 210, the water divider valve 200 can be in a state where both outlets for spraying are connected during the switching process from a position that connects only one outlet for spraying to a position that connects only the other outlet for spraying.

[0189] In the fourth and fifth embodiments of the water distribution valve 200, the valve body 210 is further provided with a third outlet 213 and a fourth outlet 214, which are respectively disposed on the bottom wall and / or side wall; three of the outlets, namely the first outlet 211, the second outlet 212, the third outlet 213 and the fourth outlet 214, are used to connect with the spray device 100, and the other outlet is used to connect with the drive device 300.

[0190] In this embodiment, the water distribution valve 200 can be provided with four water outlets. Three of these outlets can be connected to the corresponding spray mechanism of the spray device 100, and the other outlet can be connected to the drive device 300. The main difference between these two embodiments of the water distribution valve 200 and the second and third embodiments described above is that an additional water outlet is added to the valve body 210. When specifically applied in a cleaning machine, different water discharge patterns can be created by combining the three spray mechanisms.

[0191] like Figure 14 and Figure 15 As shown, in the fourth embodiment, the third outlet 213 and the fourth outlet 214 can be disposed on the bottom wall. In this case, the first outlet 211, the third outlet 213, and the fourth outlet 214 can be connected to the spray mechanism corresponding to the spray device 100; the second outlet 212 can be connected to the drive device 300. Furthermore, as... Figure 17 and Figure 18 As shown, in the fifth embodiment, the third outlet 213 and the fourth outlet 214 can be provided on the side wall. In this case, the first outlet 211 can be connected to the drive device 300, and the second outlet 212, the third outlet 213 and the fourth outlet 214 can be connected to the spraying mechanism corresponding to the spraying device 100, respectively.

[0192] When the valve body 210 is provided with a third outlet 213 and a fourth outlet 214, the water divider 220 may also be provided with at least a third connecting portion 223 and a fourth connecting portion 224. The third connecting portion 223 and the fourth connecting portion 224 can be connected to the outlet of the valve body 210 for connecting to the spray device 100.

[0193] Specifically, the third connecting part 223 and the fourth connecting part 224 are respectively disposed at the bottom and / or side of the water divider 220.

[0194] like Figure 16As shown, in the fourth embodiment, when the third connecting part 223 and the fourth connecting part 224 are spaced apart at the bottom, the first connecting part 221, the third connecting part 223 and the fourth connecting part 224 at the bottom are used to connect the three water outlets corresponding to the spray device 100.

[0195] like Figure 17 and Figure 18 As shown, in the fifth embodiment, when the third connecting part 223 and the fourth connecting part 224 are spaced apart on the side, the second connecting part 222, the third connecting part 223 and the fourth connecting part 224 provided on the side are used to connect the three water outlets corresponding to the spray device 100.

[0196] For scenarios where the cleaning machine is equipped with multiple spray mechanisms or different spray nozzles that can be combined to form two or more spray states, in order to ensure that the drive device 300 can be controlled to operate during each switching process, the structure of the water distribution valve 200 can be improved for the water outlet of the valve body 210 and the connecting part of the water distribution plate 220 that are connected to the drive device 300.

[0197] Please refer to the following: Figure 19 and Figure 20 In one embodiment, the valve body 210 is further provided with at least a fifth outlet 215 for communicating with the drive device 300, and / or the water divider 220 is further provided with at least a fifth connecting portion 225 for communicating with the outlet of the drive device 300.

[0198] In this embodiment, when the valve body 210 is provided with a plurality of outlets for communication with the drive device 300, such as a second outlet 212 and a fifth outlet 215, the fifth outlet 215 and the second outlet 212 can be spaced apart on the side wall of the valve body 210, and the second connecting part 222 is intermittently connected with the fifth outlet 215 and the second outlet 212 during the movement of the water divider 220 relative to the valve body 210.

[0199] Alternatively, when the water divider 220 is provided with multiple connecting parts for connecting to the water outlet of the drive device 300, such as the second connecting part 222 and the fifth connecting part 225, the fifth connecting part 225 and the second connecting part 222 are spaced apart on the side of the water divider 220, and the fifth connecting part 225 and the second connecting part 222 are intermittently connected to the second water outlet 212 as the water divider 220 moves relative to the valve body 210.

[0200] In this embodiment, when the water distribution valve 200 is used in a cleaning machine, the number of water outlets or connecting parts can be added adaptively according to the number of times the spray state of the cleaning machine is switched, so as to ensure that the drive device 300 can be controlled to operate during the specified switching process.

[0201] For example, the washing machine may include switching between two different spray states (switching between spraying by the first spray mechanism 110 and spraying by the second spray mechanism 120, or switching between spraying by the first spray nozzle 140 and spraying by the second spray nozzle 150). By adding a fifth water outlet 215 or a fifth connecting portion 225 that connects to the drive device 300, when the water distribution valve 200 is connected to the drive device 300, the drive device 300 is intermittently connected via the two water outlets (the second water outlet 212 and the fifth water outlet 215); or, the drive device 300 is intermittently connected via the two connecting portions (the fifth connecting portion 225 and the second connecting portion 222). This allows the washing machine to connect to the drive device 300 during the switching between the two different spray states, enabling the rotation of tableware and / or kitchen utensils. Furthermore, when... Figure 19 Valve body 210 and Figure 20 When the water divider 220 is combined, it can not only ensure that the washing machine can be connected to the drive device 300 during the switching between two different spray states to realize the rotation of tableware and / or kitchen utensils, but also use the fifth water outlet 215 and the second water outlet 212 to connect to the drive device 300 at the same time, thereby increasing the flow rate supplied to the drive device 300.

[0202] Please see Figure 20 The water divider 220 is further provided with at least a sixth connecting portion 226 and a seventh connecting portion 227 for connecting to the outlet of the driving device 300. The fifth connecting portion 225, the second connecting portion 222, the sixth connecting portion 226, and the seventh connecting portion 227 are spaced apart on the side of the water divider 220 and are intermittently connected to the second outlet 212 as the water divider 220 moves relative to the valve body 210. Alternatively, the fifth connecting portion 225, the second connecting portion 222, and the sixth connecting portion 226 are spaced apart on the side of the water divider 220 and are intermittently connected to the second outlet 212 as the water divider 220 moves relative to the valve body 210.

[0203] In this embodiment, the water divider 220 may be provided with four connecting portions for connecting to the drive device 300, namely the fifth connecting portion 225, the second connecting portion 222, the sixth connecting portion 226, and the seventh connecting portion 227. These four connecting portions are spaced apart on the side of the water divider 220, and are intermittently connected to the second water outlet 212 of the drive device 300 during the movement of the water divider 220 relative to the valve body 210. When the water divider valve 200 with the water divider 220 is used in a cleaning machine, it can ensure that the drive device 300 can be activated during the switching of the four different spray states of the cleaning machine. Specifically, the four different spray states can be referred to the detailed description of the control method of the cleaning machine above, and will not be elaborated here.

[0204] Furthermore, the water divider 220 can also be provided with three connecting parts for connecting to the drive device 300, namely the fifth connecting part 225, the second connecting part 222, and the sixth connecting part 226. These three connecting parts are spaced apart on the side of the water divider 220, and are intermittently connected to the second water outlet 212 of the drive device 300 during the movement of the water divider 220 relative to the valve body 210. When the water divider valve 200 with the water divider 220 is used in a cleaning machine, it can ensure that the drive device 300 can be activated during the switching of the three different spray states of the cleaning machine. Specifically, the three different spray states can be one less than the above four spray states. The specific reduction scheme can be set according to the actual product design, and this application does not make specific limitations here.

[0205] Based on the structural improvements to the connecting portion of the water divider 220, the structural improvements to the outlet of the valve body 210 can also be deduced by analogy.

[0206] Specifically, the valve body 210 is further provided with at least a sixth water outlet or a sixth water outlet and a seventh water outlet for communication with the drive device 300. The fifth water outlet 215, the sixth water outlet, and the second water outlet 212 are spaced apart on the side wall of the valve body 210. The second connecting part 222 is intermittently connected with the fifth water outlet 215, the sixth water outlet, and the second water outlet 212 during the movement of the water divider 220 relative to the valve body 210. Alternatively, the fifth water outlet 215, the sixth water outlet, the seventh water outlet, and the second water outlet 212 are spaced apart on the side wall of the valve body 210. The second connecting part 222 is intermittently connected with the fifth water outlet 215, the sixth water outlet, the seventh water outlet, and the second water outlet 212 during the movement of the water divider 220 relative to the valve body 210.

[0207] The structural improvement of the outlet on the valve body 210 can be compared with the structural improvement of the connecting part on the water divider 220. The two can produce equivalent technical effects. This application will not describe it in detail with reference to the accompanying drawings.

[0208] Overall, in a cleaning cycle, when there are N switching processes between different spray states (the first spray state and the second spray state), the number of water outlets of the valve body 210 used to connect the drive device 300 is at least N, and / or the number of connecting parts of the water divider 220 used to connect the drive device 300 is at least N.

[0209] In this embodiment, during one cleaning cycle, the water divider 220 rotates one revolution relative to the valve body 210. When the switching process between different spray states of the spray device 100 can be N (N is a positive integer greater than or equal to 2), the number of water outlets of the valve body 210 used to connect to the drive device 300 is at least N, and / or the number of connecting parts of the water divider 220 used to connect to the drive device 300 is at least N. This ensures that during the N switching processes, the water divider valve 200 can be used to connect to the drive device 300, thereby driving the tableware and / or kitchen utensils to rotate.

[0210] like Figure 1 As shown, in one embodiment, the spraying device 100 includes at least a first spraying mechanism 110 and a second spraying mechanism 120. The valve body 210 is provided with a first outlet 211 for connecting the first spraying mechanism 110, a second outlet 212 for connecting the driving device 300, and a third outlet 213 for connecting the second spraying mechanism 120.

[0211] In this embodiment, the spraying device 100 may include at least two spraying mechanisms, namely a first spraying mechanism 110 and a second spraying mechanism 120. The first outlet 211 on the valve body 210 can be used to connect to the first spraying mechanism 110, the second outlet 212 on the valve body 210 can be used to connect to the drive device 300, and the third outlet 213 on the valve body 210 is used to connect to the second spraying mechanism 120.

[0212] Specifically, during the rotation of the water divider 220 relative to the valve body 210, when the water divider 220 is in the first position, it is connected to the first spray mechanism 110 or both the first spray mechanism 110 and the driving device 300; when the water divider 220 is in the second position, it is connected to the second spray mechanism 120 or both the second spray mechanism 120 and the driving device 300; when the water divider 220 is in the third position, it is only connected to the driving device 300, and the water divider 220 passes through the third position during the rotation from the first position to the second position.

[0213] When the water divider 220 rotates relative to the valve body 210, it connects to the drive device 300 during the switching of the spray state, effectively utilizing the switching time of the spray state to rotate the tableware and / or kitchenware being cleaned, which can make the rinsing more uniform, the cleaning effect better, and the cleaning efficiency higher.

[0214] The following example illustrates the scenario where the spray device 100 has a first spray mechanism 110 and a second spray mechanism 120, taking the example of the spray device 100 changing from the first spray state to the second spray state. When the spray device 100 is in the first spray state, the water distribution valve 200 can be connected only to the first spray mechanism 110. After the water distribution plate 220 rotates a certain angle relative to the valve body 210, the water distribution valve 200 can be connected to both the first spray mechanism 110 and the drive device 300 simultaneously. Then, after the water distribution plate 220 rotates a certain angle relative to the valve body 210 again, the water distribution valve 200 can be connected only to the drive device 300. Further, after the water distribution plate 220 rotates a certain angle relative to the valve body 210, the water distribution valve 200 can be connected to both the second spray mechanism 120 and the drive device 300 simultaneously. Then, after the water distribution plate 220 rotates a certain angle relative to the valve body 210, the water distribution valve 200 can be connected only to the second spray mechanism 120. This not only realizes the switching between the first and second spray states, but also realizes the rotation of tableware and / or kitchen utensils during the switching process.

[0215] The rotation speed of the water divider 220 can be determined comprehensively based on the required rotation angle of the tableware and / or kitchen utensils, as well as the structure and size of the water divider valve 200 itself. This application does not limit the specific value here.

[0216] For a water distribution valve 200 with a specific shape and structure, when the motor 240 drives the water distribution plate 220 to rotate, the motor 240 can rotate at a preset speed. When the speed of the motor 240 is determined, it is only necessary to obtain the working time of the motor 240 to control the angle through which the water distribution plate 220 rotates relative to the valve body 210, thereby controlling the connection between the water distribution valve 200 and the spray device 100 and the drive device 300.

[0217] like Figure 3 As shown, in another embodiment, the spray device 100 includes a spray mechanism, which includes a first spray port 140 and a second spray port 150. The valve body 210 is provided with a first outlet 211 for connecting to the first spray port 140, a second outlet 212 for connecting to the drive device 300, and a third outlet 213 for connecting to the second spray port 150.

[0218] In this embodiment, the main difference from the above embodiments is that the spraying device 100 includes only one spraying mechanism, which includes multiple spray nozzles, such as a first spray nozzle 140 and a second spray nozzle 150. Specifically, the first outlet 211 on the valve body 210 is connected to the first spray nozzle 140, the second outlet 212 on the valve body 210 is connected to the drive device 300, and the third outlet 213 on the valve body 210 is connected to the second spray nozzle 150.

[0219] The switching process and principle of the connection between the water distribution plate 220 in the water distribution valve 200 and the spray device 100 and the drive device 300 during the rotation of the water distribution plate 220 relative to the valve body 210 can be referred to the description of the above embodiments, and will not be repeated here.

[0220] Please refer to the following: Figure 21 In a specific application scenario, taking dishwashing as an example, the basic control logic of the dishwashing machine and its operation provided in this application is as follows:

[0221] After the cleaning machine is turned on, the first steps are to fill it with water and start the water pump.

[0222] Then the spray device enters the first spray state, which can be maintained for X minutes; specifically, X can be a preset value, or some optional values, or a time that is automatically matched according to the difficulty of washing the bowl, etc. The value of X is not specifically limited in this application.

[0223] Just before, at the exact end, or after the first spray state has ended, the drive device is activated using the water distribution valve; the bowl is rotated for Q seconds; specifically, Q can be a preset value, some optional values, or a time automatically matched according to the actual rotation speed of the bowl, the size of the bowl itself, etc., and this application does not specifically limit the value of Q.

[0224] Just before, at the exact end, or after the bowl rotation has ended, the water distribution valve is used to switch the spray device to enter the second spray state, which can be maintained for Y minutes. Similarly, Y can be a preset value, some optional values, or a time that is automatically matched according to the difficulty of washing the bowl. The value of Y is not specifically limited in this application.

[0225] Just before, just as, or after the second spraying state ends, the drive device is activated using the water distribution valve; the bowl is rotated for Q seconds; specifically, Q can be a preset value, some optional values, or a time automatically matched according to the actual rotation speed of the bowl, the size of the bowl itself, etc. This application does not specifically limit the value of Q.

[0226] Just before, at the exact end, or after the bowl rotation has finished, use the water distribution valve to switch back to the first spray state, completing one cleaning cycle.

[0227] The above is a brief description of the operating principle of the cleaning machine provided by the present invention, using only an embodiment with two different spray states. Because the water distribution valve in this application allows the bowl to rotate during the switching between the two spray states, the cleaning machine's operation is significantly improved.

[0228] During the operation of this washing machine, the washing time can be monitored. If the washing time has not yet reached M minutes, the washing cycle can continue. Once the washing time reaches M minutes, drainage is performed, and the washing is complete. The specific value of M can be a pre-set value or several pre-set values. For example, the washing machine can have multiple washing modes, each corresponding to a different M value. When the user selects a washing mode, the value of M is determined. Specifically, this application does not limit the value of M. However, through the applicant's experimental verification, it is certain that using the washing machine provided in this application, compared to existing washing machines, the value of M can be significantly reduced to achieve the same cleaning effect; or, with the same washing time, the dishes washed using the washing machine provided in this application achieve a better cleaning effect.

[0229] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.

[0230] The various embodiments described in this specification are presented in a progressive manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0231] The above are merely a few embodiments of the present invention.

Any person skilled in the art to which this invention pertains may make any modifications and changes in the form and details of the embodiments without departing from the spirit and scope disclosed in the present invention. However, the patent protection scope of the present invention shall still be determined by the scope defined in the appended claims.
