Description

[0001] This application is a divisional application of application number "202110704697.0", filed on "June 24, 2021", and entitled "Cleaning Machine and Control Method Thereof". Technical Field

[0002] This invention relates to the field of tableware cleaning equipment technology, and in particular to a cleaning machine and its control method. Background Technology

[0003] A dishwasher is a device used to automatically clean dishes. Because washing dishes with a dishwasher greatly reduces tedious manual labor, is easy to operate, and has a high degree of automation, it has become increasingly popular among consumers.

[0004] Existing dishwashers typically include: at least one nozzle, and a frame located above the nozzle for placing dishes to be washed. During washing, the user places the dishes into the frame, starts the dishwasher, and the water sprayed from the nozzle automatically rinses the dishes in the frame.

[0005] However, the applicant discovered that the cleaning effect achieved by using existing dishwashers was not ideal. For example, due to limitations in placement, number of nozzles, and spray arm movement trajectory, only certain areas of the dishes could be directly rinsed by the spray arm's water flow, while the rest could only be rinsed by splashing water. When food residue that was difficult to remove adhered to the dishes, even after the dishwasher's automatic cleaning, residue would still remain in the areas rinsed by splashing water. Summary of the Invention

[0006] The purpose of this invention is to provide a cleaning machine and its control method that can achieve the best overall effect in terms of cleaning effect, cleaning time and energy consumption, and can quickly achieve better cleaning effect with lower energy consumption in a shorter cleaning time.

[0007] The above-mentioned objectives of the present invention can be achieved by the following technical solutions: A cleaning machine includes: a spray device for spraying and cleaning tableware and / or kitchenware; a transmission device for providing rotational power to the tableware and / or kitchenware when the tableware and / or kitchenware are located on the transmission device; a first flow path for allowing spray liquid to flow through the first flow path to the spray device; a drive device for driving the transmission device, the drive device including: an electric drive device that intermittently drives the transmission device to drive the tableware and / or kitchenware to rotate intermittently; and / or, a second flow path, in which fluid drives the transmission device. The cleaning machine further includes a flow control device for adjusting the flow rate of the second flow path and / or controlling the on / off state of the second flow path, thereby controlling the intermittent rotation of the tableware and / or kitchenware.

[0008] Furthermore, when the tableware and / or kitchenware are located in the transmission device, rotational power is provided to the tableware and / or kitchenware based on the friction between the tableware and / or kitchenware and the transmission device.

[0009] Furthermore, the flow control device is used to adjust the flow rate of the first flow path and / or the flow rate of the second flow path.

[0010] Furthermore, the flow control device includes a pump and / or a flow control element, wherein when the flow control device includes the pump and the flow control element, the pump is located upstream or downstream of the flow control element.

[0011] Furthermore, the pump includes a first pump and a second pump, the first pump being used to supply spray liquid to the spraying device through the first flow path, and the second pump being used to provide driving force to the transmission device through the second flow path.

[0012] Furthermore, the first flow path has a first end and a second end, the first end being connected to the flow control device and the second end being connected to the spray device; the second flow path has a third end and a fourth end, the third end being connected to the flow control device and the fourth end being connected to the transmission device.

[0013] Furthermore, the flow control component includes a three-way flow regulating valve.

[0014] Furthermore, the transmission device is disposed in the washing chamber of the washing machine, or the transmission device is disposed on the basket inside the washing machine, or the transmission device is disposed above the spray device of the washing machine, or when the spray device of the washing machine includes at least two spray devices arranged vertically, the transmission device is disposed between the at least two spray devices.

[0015] Furthermore, the pump has a first operating state that can supply spray liquid to the spray device and drive the transmission device, and a second operating state that supplies spray liquid only to the spray device. The operating parameters of the pump in the first operating state are different from those in the second operating state.

[0016] Furthermore, the flow control component includes a first flow regulating valve and a second flow regulating valve, wherein the first flow regulating valve is disposed in the first flow path and the second flow regulating valve is disposed in the second flow path.

[0017] Furthermore, when the flow control device is a pump, the flow cross-sectional area of ​​the first flow path is different from the flow cross-sectional area of ​​the second flow path.

[0018] A control method for a cleaning machine based on any of the above-described methods includes: intermittently adjusting the flow rate of the second flow path to drive the transmission device to intermittently rotate the tableware and / or kitchenware, and / or, the electric drive device intermittently driving the transmission device to intermittently rotate the tableware and / or kitchenware.

[0019] Furthermore, the cleaning machine includes a flow control device for adjusting the flow rate of the first flow path and / or the flow rate of the second flow path, and the method further includes: intermittently adjusting the flow rate of the first flow path based on the flow control device to cause the spraying device to spray intermittently.

[0020] Furthermore, the control method specifically includes, S101. Connect the flow control device only to the first flow path, and spray the tableware and / or kitchenware for a first duration. S103. Connect the flow control device to the second flow path only, so as to drive the transmission device to rotate the tableware and / or kitchenware by a first angle; S105. Repeat S101 and S103 until the total rotation angle of the tableware and / or kitchenware reaches the preset angle.

[0021] Furthermore, the spraying device rotates and sprays, and within at least two rotation cycles, at least the same spray nozzle on the spraying device sprays at least partially different areas on the same tableware and / or kitchenware.

[0022] Furthermore, when the cleaning machine cleans tableware and / or kitchen utensils, the flow control device remains connected to the first flow path, ensuring that the spraying device remains in spraying mode.

[0023] Furthermore, the control method specifically includes: The first flow path is kept in constant communication with the flow control device, and the tableware and / or kitchenware are constantly sprayed and cleaned. At the same time, the flow rate of the second flow path is intermittently adjusted based on the flow control device, and the transmission device is driven to rotate the tableware and / or kitchenware intermittently by a first angle until the total rotation angle of the tableware and / or kitchenware reaches a preset angle.

[0024] As can be seen from the technical solutions provided by the above embodiments of this application, the cleaning machine and its control method provided by this application can form a variety of different cleaning schemes by reasonably controlling the coordination between the spray device, the transmission device and the flow path and the drive device, so as to achieve the best comprehensive effect in terms of cleaning effect, cleaning time and energy consumption. It can quickly achieve a better cleaning effect with lower energy consumption in a shorter cleaning time.

[0025] When the drive unit causes the transmission device to rotate the tableware and / or kitchenware intermittently, the rotation of the tableware and / or kitchenware allows different parts of the tableware and / or kitchenware to be cleaned when the spray device is in the same position, thereby increasing the cleaning coverage. At the same time, when the spray device and the drive unit share the same pump, the pump pressure can be concentrated on cleaning the tableware and / or kitchenware that have stopped rotating during the intervals when the tableware and / or kitchenware have stopped rotating, further ensuring the cleaning effect.

[0033] Please refer to the following: Figures 1 to 7 A cleaning machine provided in this application embodiment may include: a spray device 100 for spraying and cleaning tableware and / or kitchenware; a transmission device 200 for providing rotational power to the tableware and / or kitchenware when the tableware and / or kitchenware are located in the transmission device 200; a first flow path 400 for allowing spray liquid to flow through the first flow path 400 to the spray device 100; a drive device 300 for driving the transmission device 200; the drive device 300 includes an electric drive device 300; and / or a second flow path 500, wherein the fluid in the second flow path 500 is used to drive the transmission device 200.

[0034] In this specification, the cleaning machine can specifically be a dishwasher, used to clean tableware, kitchen utensils, and other items. Tableware can include bowls, plates, dishes, chopsticks, etc., and kitchen utensils can include pots, pans, etc. In addition, the cleaning machine can also be used to clean items that are the same size and similar in structure to 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 referred to this specification, and will not be detailed here.

[0035] The washing machine may also be provided with a washing chamber 910, which is used to form a space for accommodating and washing tableware and / or kitchen utensils. The washing chamber 910 may also be provided with an outer shell 920.

[0036] 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 820, to provide water softened by the water softening module 820 to the spray device 100.

[0037] 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, or a combination of both, or other forms of drive can also be combined.

[0038] Specifically, the spraying device 100 may include a spraying arm with nozzles. Of course, the spraying device 100 may also include other structures or other forms. This application does not make specific limitations here.

[0039] The washing machine is equipped with a transmission device 200, which provides rotational power to the tableware and / or kitchenware when they are located within the transmission device 200. Specifically, the transmission device 200 drives the tableware and / or kitchenware to rotate relative to the fixed structure of the washing machine (e.g., the washing chamber 910). The power source for the transmission device 200 can be electric, hydraulic, a combination of both, or other power driving methods or a combination of multiple power driving methods.

[0040] Please refer to the following: Figure 1 , Figure 8 , Figure 9 , Figure 10 When the transmission device 200 is hydraulically driven, the transmission device 200 includes: a transmission assembly; the transmission assembly is fitted with a flow channel, the flow channel having a fluid inlet end 253 and a fluid outlet end, the fluid inlet end 253 is used to receive fluid, and the fluid outlet end is used to export the fluid to the transmission assembly, so that when tableware and / or kitchenware are in contact with the transmission assembly, the tableware and / or kitchenware rotate based on the force between the tableware and / or kitchenware and the transmission assembly.

[0041] The flow channel can be any form capable of guiding fluid to the transmission component.

[0042] like Figure 10 As shown, for example, the transmission device 200 is provided with a housing 240, and the flow channel can be an internal flow path disposed within the housing 240 of the transmission assembly. Specifically, when the transmission device 200 includes a housing 240, the transmission assembly is disposed within the housing 240, the flow channel is disposed on the housing 240, and the housing 240 is also provided with a fluid outlet. The fluid discharged from this fluid outlet can flow into a designated area, such as a water cup 810, for subsequent recycling.

[0043] Alternatively, the transmission device 200 may be provided with a housing 240, which has an opening. The outlet end of the flow channel may be connected to the opening of the housing 240, and its inlet end may be connected to other water circuit equipment or water source. It should be noted that since the housing 240 itself has a certain wall thickness, the opening provided on the housing 240 may also be regarded as the flow channel.

[0044] Alternatively, the transmission device 200 may not have a housing 240. The flow channel can be an external pipe of the transmission device 200, with its inlet end connected to other water equipment or a water source, and the fluid flowing out of its outlet end driving the transmission device 200. In one embodiment, such as... Figure 11As shown, the transmission device 200 does not have a separate housing 240 outside the transmission assembly. The outlet end of the flow channel can be the outlet end of a water outlet device, for example, the flow channel can be the spray nozzle of the spray device 100. When tableware and / or kitchen utensils are in contact with the transmission assembly, the friction between the tableware and / or kitchen utensils and the transmission device 200 provides rotational power to the tableware and / or kitchen utensils. Of course, the flow channel can also be an independent pipe connected to a water source, and is not limited to the aforementioned form integrated into the spray nozzle.

[0045] Please refer to the following: Figure 10 In one embodiment, the fluid outlet end is at least partially located above the transmission assembly, and / or, the fluid outlet end is at least partially located to the side of the transmission assembly. When the fluid outlet end is at least partially located above and / or to the side of the transmission assembly, a portion of the fluid's gravity can be used as a driving force, thereby reducing the fluid pressure required to drive the transmission assembly.

[0046] In one embodiment, the transmission assembly includes at least a first transmission member 210 and a second transmission member 220. The fluid outlet end is used to discharge fluid to the first transmission member 210, which rotates under the action of the fluid, and the second transmission member 220 rotates along with the first transmission member 210. Further, the transmission assembly may also include a third transmission member 230 that rotates with the second transmission member 220. The third transmission member 230 is used to contact the tableware and / or kitchenware, and the tableware and / or kitchenware rotate with the third transmission member 230 under the action of friction generated by the contact.

[0047] The first transmission member 210 can be in the form of a rotating component, such as an impeller, capable of rotation under the action of a fluid. The first transmission member 210 may include at least one impeller. The second transmission member 220 can be in the form of a rotating shaft that drives the impeller. The second transmission member 220 may include a rotating shaft located at the center of the at least one impeller.

[0048] The impeller and the rotating shaft are detachably connected or integrally formed. When the impeller and the rotating shaft are detachably connected, a transmission structure can be formed between them. This transmission structure can specifically be a keyway and key mating structure, or other forms of transmission structure, which are not specifically limited herein.

[0049] The third transmission member 230 is sleeved around the second transmission member 220, or the third transmission member 230 is integrally formed with the second transmission member 220. When the third transmission member 230 is sleeved around the second transmission member 220, a transmission engagement structure can be formed between them, thereby enabling the second transmission member 220 to drive the third transmission member 230 to rotate. This transmission engagement structure can be a keyway and key engagement structure, or other forms of transmission structure; this application does not impose specific limitations on it.

[0050] Generally, there are multiple third transmission components 230, which can be spaced apart along the axial direction of the second transmission component 220. When the third transmission component 230 is fitted around the second transmission component 220, it can move axially relative to the transmission component, thereby changing its position on the transmission shaft and thus flexibly adapting to tableware and / or kitchenware of different sizes. In addition, as a consumable component that comes into direct contact with tableware and / or kitchenware, the third transmission component 230, when positioned circumferentially around the second transmission component 220, also facilitates its maintenance and replacement.

[0051] The third transmission component 230 is mainly used to increase the coefficient of friction and contact area between the transmission assembly and tableware and / or kitchen utensils. The third transmission component 230 can be made of a softer material with a higher coefficient of friction than the second transmission component 220. For example, the material of the third transmission component 230 can be rubber or similar materials. Of course, the third transmission component 230 can also be made of other materials, and this application does not impose specific limitations here. Furthermore, the shape of the third transmission component 230 can be a rotary body, with different axial and radial dimensions along the axis of rotation. Of course, the third transmission component 230 can also have other regular or irregular shapes, and this application does not impose specific limitations here.

[0052] Referring to reference 5, the fluid outlet end is used to directly discharge the fluid onto the blades of the at least one impeller. Specifically, the fluid outlet end may at least partially face at least one blade of the impeller.

[0053] When the fluid exiting the fluid outlet flows onto the impeller blades, it drives the impeller to rotate, which in turn drives the shaft to rotate, thereby causing the tableware and / or kitchen utensils to rotate. When the shaft is equipped with a third transmission component 230, the fluid exiting the fluid outlet flows onto the impeller blades, driving the impeller to rotate, which in turn drives the shaft and the third transmission component 230 on the shaft to rotate, thereby causing the tableware and / or kitchen utensils to rotate.

[0054] In addition to the above-described embodiment where the fluid flowing out of the fluid outlet is directly discharged onto the impeller blades, the fluid flowing out of the fluid outlet can also drive the impeller to rotate in other ways.

[0055] Please refer to the following: Figures 12 to 13 For example, in one embodiment, the impeller has an inlet at its center that is opposite to or connected to the fluid outlet end. This inlet is used to guide fluid discharged from the fluid outlet end into one side of the impeller, thereby driving the impeller to rotate. Specifically, the impeller may have one or more outlets along its circumference (the illustration shows a case with multiple outlets). When fluid introduced into the impeller through the fluid outlet end flows out of the outlet, the appropriate setting of the outlet's outflow direction can drive the impeller to rotate.

[0056] Please see Figure 10 , Figure 11 In one specific embodiment, the first transmission component 210 includes a first impeller 211 and a second impeller 212, and the second transmission component 220 includes a first rotating shaft located in the middle of the first impeller 211 and a second rotating shaft located in the middle of the second impeller 212. The impeller and the rotating shaft are detachably connected or integrally formed.

[0057] Furthermore, both the first impeller 211 and the second impeller 212 can be fluid-driven driving impellers. Of course, in some embodiments, one of the first impeller 211 and the second impeller 212 can be a driven impeller. When both the first impeller 211 and the second impeller 212 are driving impellers, the fluid outlet end can include a first outlet end 251 and a second outlet end 252. The first outlet end 251 is at least partially located above and / or to the side of the first impeller 211, and the second outlet end 252 is at least located above and / or to the side of the second impeller 212, thereby facilitating efficient driving of the first impeller 211 and the second impeller 212. It should be noted that in other embodiments, the first outlet end 251 and the second outlet end 252 can also be located in other positions of the first impeller 211 and the second impeller 212, such as below.

[0058] Furthermore, when the rotating shaft includes a first rotating shaft and a second rotating shaft, the distance between the first rotating shaft and the second rotating shaft is adjustable to accommodate tableware and / or kitchen utensils of different sizes. The adjustment scheme for the distance between the first rotating shaft and the second rotating shaft can vary depending on the specific form of the first impeller 211 and the second impeller 212. For example, when the first impeller 211 is a driving wheel and the second impeller 212 is a driven wheel, the position of the second rotating shaft corresponding to the driven wheel can be adjusted to achieve the adjustment of the distance between the two rotating shafts. Of course, the distance between the first rotating shaft and the second rotating shaft can also be adjusted in other ways, which will not be elaborated upon here.

[0059] In one embodiment, the transmission device 200 is provided with at least one tableware placement area and / or kitchen utensil placement area. The tableware placement area and the kitchen utensil placement area can be the same area or different areas. Specifically, the transmission device 200 may also be provided with a support mechanism, which mainly forms the frame of the transmission device 200 and cooperates with the rotating shaft to form at least one tableware placement area and / or kitchen utensil placement area.

[0060] In some cases, when the tableware and / or cookware rotates relative to the washing chamber 910, the tableware and / or cookware may only rotate on their own axis. In this case, the angle or state of rotation of the tableware and / or cookware at different positions may be the same or different. In addition, in other cases, the tableware and / or cookware may also rotate synchronously with at least a portion of the transmission components it contacts.

[0061] Specifically, when the tableware and / or kitchenware are located in the transmission device 200, rotational power is provided to the tableware and / or kitchenware based on the frictional force between the tableware and / or kitchenware and the transmission device 200. For example, during rotation, the transmission component in the transmission device 200 can generate a large static frictional force with the tableware and / or kitchenware, thereby driving the tableware and / or kitchenware to rotate. Of course, the specific methods of using the transmission device 200 to drive the tableware and / or kitchenware to rotate are 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.

[0062] The cleaning machine is equipped with a first flow path 400, which allows the spray liquid to flow to the spraying device 100. Specifically, the first flow path 400 connects the liquid supply system to the spraying device 100, thereby guiding the spray liquid from the liquid supply system to the spraying device 100. When the spraying device 100 is in a rotating spraying state during operation, the fluid provided by the first flow path 400 can also provide rotational power to the spraying device 100.

[0063] The first flow path 400 can take the form of a pipeline or similar structure. The form and connection relationship of the first flow path 400 can be set according to the specific composition of the actual product and the functions it performs, and this application does not impose any specific limitations on them.

[0064] The cleaning machine is equipped with a drive unit 300 for driving the transmission device 200. The drive unit 300 may include an electric drive unit 300, a hydraulic drive unit 300, or a combination of both. The hydraulic drive unit 300 may include a second flow path 500. Fluid in the second flow path 500 drives the transmission device 200. When the drive unit 300 includes a hydraulic drive, the first flow path 400 may also be connected to the transmission device 200 to provide rotational power. When the drive unit 300 includes an electric drive unit 300, the electric drive unit 300 may be in the form of a motor drive; other drive forms are also possible, and this application does not specifically limit the specific types.

[0065] For the cleaning machine provided in this manual, by reasonably controlling the coordination between the spray device 100, the transmission device 200 and the flow path and drive device 300, a variety of different cleaning schemes can be formed to achieve the best overall effect in terms of cleaning effect, cleaning time and energy consumption.

[0066] Please refer to the following: Figure 1 , Figure 5 , Figure 6 and Figure 7 In one embodiment, the cleaning machine may further include a flow control device 600 for adjusting the flow rate of the first flow path 400 and / or the flow rate of the second flow path 500.

[0067] When the flow control device 600 is used to adjust the flow rate of the first flow path 400, the intermittent spray control of the spray device 100 can be achieved by adjusting the flow rate of the first flow path 400 through the flow control device 600. For example, when the flow control device 600 connects the first flow path 400 to the liquid supply system, the nozzle device is in the spraying state; when the flow control device 600 disconnects the first flow path 400 from the liquid supply system, the spray device 100 is in the stopped spraying state, and the two states are switched periodically to form intermittent spraying.

[0068] Furthermore, when the flow rate of the first flow path 400 reaches a certain level, the spray liquid at a specific flow rate can not only meet the spraying needs of tableware and / or kitchen utensils, but also drive the spray device 100 to rotate, or provide rotational power to the drive device 300, or provide rotational power to the drive device 300 while driving the spray device 100 to rotate. The different functions that the first flow path 400 can achieve for different flow rates can vary depending on the specific structure of the spray device 100, the cross-sectional area of ​​the first flow path 400, and the cooperation relationship between the spray device 100 and the drive device 300, etc. This application does not impose specific numerical limitations here.

[0069] When the flow control device 600 is used to regulate the flow rate of the second flow path 500, the intermittent rotation of tableware and / or kitchen utensils can be controlled by regulating the flow rate of the second flow path 500 through the flow control device 600. For example, when the flow control device 600 connects the second flow path 500 to the liquid supply system, the tableware and / or kitchen utensils can be in a rotating state; when the flow control device 600 disconnects the second flow path 500 from the liquid supply system, the tableware and / or kitchen utensils can be in a stationary state. The two states switch periodically, forming intermittent rotation.

[0070] Generally, the transmission device 200 can only drive the tableware and / or kitchen utensils to rotate when the flow rate of the second flow path 500 reaches a certain level. Therefore, the flow control device 600 can directly control the on / off state of the second flow path 500, and also control the flow rate of the second flow path 500. Overall, when the flow control device 600 controls the flow rate of the second flow path 500 to be less than a preset flow rate value, the tableware and / or kitchen utensils cannot be driven to rotate. The preset flow rate value can vary depending on the specific product and the items being cleaned; this application does not impose a specific numerical limit on it.

[0071] When the flow control device 600 is used to adjust the flow of the first flow path 400 and the second flow path 500, it can realize the function of controlling the flow of the first flow path 400 or the second flow path 500 separately. The specific details will not be elaborated here.

[0072] Specifically, the flow control device 600 includes a pump 700 and / or a flow control element. When the flow control device 600 includes the pump 700 and the flow control element, the pump 700 can be located upstream or downstream of the flow control element.

[0073] The pump 700 can be used to pressurize the fluid flowing through it. There can be one pump 700, which can be located upstream of the flow control unit, for pressurizing the fluid in the first flow path 400 and the second flow path 500. Furthermore, the pump 700 may include a first pump 701 and a second pump 702. The first pump 701 supplies spray liquid to the spray arm through the first flow path 400, and the second pump 702 provides driving force to the transmission device 200 through the second flow path 500.

[0074] The flow control device can control the flow rate into the first flow path 400 and the second flow path 500. Specifically, the first flow path 400 has a first end and a second end, the first end of which is connected to the flow control device 600, and the second end of which is connected to the spray device 100; the second flow path 500 has a third end and a fourth end, the third end of which is connected to the flow control device 600, and the fourth end of which is connected to the transmission device 200. Note that the above connections only indicate a physical connection between the two, and not a connection in the waterway.

[0075] Please refer to the following: Figure 1 and Figure 2 In one embodiment, the flow control component includes a three-way flow regulating valve 603. In this embodiment, the flow control component can be in the form of a three-way flow regulating valve 603. When fluid supplied from the upstream pipeline flows through the three-way flow regulating valve 603, the flow rate of the fluid flowing to the spray device 100 and / or the drive device 300 can be controlled by adjusting the connecting device or opening degree of the three-way flow regulating valve 603.

[0076] The flow control device 600 may include a pump 700 and a flow control element. In this case, the flow control element is mainly used for flow regulation, while the pump 700 is mainly used to pressurize the fluid flowing through it. It should be noted that the upstream and downstream relationship between the flow control element and the pump 700 is not limited in this application. The pump 700 may be located upstream or downstream of the flow control element.

[0077] like Figure 3 As shown, in one embodiment, the flow control component includes a first flow regulating valve 601 and a second flow regulating valve 602. The first flow regulating valve 601 is disposed in the first flow path 400, and the second flow regulating valve 602 is disposed in the second flow path 500. When fluid supplied from the upstream pipeline flows to the first flow regulating valve 601 and the second flow regulating valve 602, the flow direction of the fluid to the spray device 100 and / or the drive device 300 can be controlled by adjusting the opening degree or on / off state of the first flow regulating valve 601 and the second flow regulating valve 602.

[0078] like Figure 4 As shown, in one embodiment, when the flow control device 600 is a pump 700, the flow cross-sectional area of ​​the first flow path 400 is different from the flow cross-sectional area of ​​the second flow path 500.

[0079] When the cross-sectional areas of the first flow path 400 and the second flow path 500 are different, the pressure of the fluid output from the first flow path 400 and the second flow path 500 can be adjusted by combining the operating parameters of the pump 700. Even if the fluid is pressurized by the same pump 700, the pressure of the output fluid will be different after passing through the first flow path 400 and the second flow path 500. Preferably, from the perspective of reliably driving the tableware and / or kitchen utensils to rotate, the cross-sectional area of ​​the second flow path 500 can be made smaller than the cross-sectional area of ​​the first flow path 400 to ensure that the fluid in the second flow path 500 has a larger pressure. Of course, from the perspective of ensuring the cleaning pressure of the spray device, preferably, the cross-sectional area of ​​the second flow path 500 can be made larger than the cross-sectional area of ​​the first flow path 400 to ensure that the fluid in the first flow path 400 has a larger pressure.

[0080] Specifically, the pump 700 has a first operating state that supplies spray liquid to the spray device 100 and drives the transmission device 200, and a second operating state that supplies spray liquid only to the spray device 100. The operating parameters of the pump 700 in the first operating state are different from those in the second operating state. The pump 700 is a water pump with adjustable operating parameters, specifically including: the pump 700's rotational speed, head, and flow rate. Taking rotational speed as an example, in the first operating state, the pump 700 can operate at a first rotational speed; in the second operating state, the pump 700 can operate at a second rotational speed, where the first rotational speed is greater than the second rotational speed.

[0081] In the second embodiment provided in this specification, the first flow path 400 and the second flow path 500 can be integrated into the spray device 100.

[0082] Please refer to the following: Figure 5 At least a portion of the first flow path 400 and the second flow path 500 are integrated into the same flow path of the spray device 100; or, at least a portion of the first flow path 400 and the second flow path 500 are respectively arranged in different flow paths of the spray device 100.

[0083] Specifically, when at least a portion of the first flow path 400 and the second flow path 500 are integrated into the same flow path of the spray device 100, the integrated flow path can be a guide channel formed inside the spray device 100. Multiple nozzles are provided at the end of this guide channel. For the same nozzle, the ejected fluid can be used to spray and clean tableware and / or kitchen utensils, and can also drive the transmission device 200 to provide rotational power for the tableware and / or kitchen utensils.

[0084] Please refer to the following: Figure 14 and Figure 15 When at least a portion of the first flow path 400 and the second flow path 500 are respectively arranged in different flow paths of the spray device 100, the second flow path 500 arranged in the spray device 100 may include a guide pipe 110 passing through the interior of the spray device 100. The spray device 100 may have an opening for the guide pipe 110 to pass through. The end of the guide pipe 110 passes through the opening, and the fluid is guided to the transmission device 200 after passing through the end of the guide pipe 110. The guide pipe 110 may be a spray pipe on the spray device 100 that itself performs a spraying function, or it may be a pipe newly added based on the original opening of the spray device 100.

[0085] Wherein, when the second flow path 500 and the first flow path 400 are not integrated into the same flow path, the fluid flowing through the first flow path 400 is used not only as spray liquid, but also as spraying at least a portion of the spray liquid toward the transmission device 200, so as to provide rotational power for the tableware and / or kitchenware when the tableware and / or kitchenware are located in the transmission device 200.

[0086] Specifically, the spray arm of the spray device 100 may have multiple openings, some of which can be used as spray holes to direct fluid to tableware and / or kitchen utensils, while other openings can direct fluid to the transmission device 200, thereby driving the transmission device 200 to rotate.

[0087] like Figure 7 As shown, the drive device 300 can be in the form of an electric drive device 300, for example, the drive device 300 can be a motor.

[0088] In one embodiment, the transmission device 200 can be disposed inside the washing chamber 910, and the electric drive device 300 can be disposed outside the washing chamber 910. When the electric drive device 300 is disposed outside the washing chamber 910, it can avoid direct contact with the fluid inside the washing chamber 910, thereby reducing the waterproof rating of the electric drive device 300 and improving its reliability and service life. Specifically, for a washing machine with a housing 920, the electric drive device 300 can be disposed on the outer wall of the washing chamber 910 or the inner wall of the washing machine housing 920.

[0089] When the transmission device 200 is installed in the washing chamber 910, in addition to being driven by the electric drive device 300, it can also be driven by water power or by water power alone, which improves the flexibility of starting the transmission device 200 and the reliability of its operation.

[0090] In this embodiment, the transmission device 200 can be disposed within the washing chamber 910 of the washing machine. Specifically, the transmission device 200 is disposed on the basket inside the washing machine, resulting in high integration and space-saving performance. Alternatively, the transmission device 200 can be disposed above the spray device 100 of the washing machine. Especially when there is only one spray device 100, interference with the transmission device 200 can be avoided, ensuring that the water sprayed from the spray arm thoroughly cleans the tableware and / or kitchenware. Alternatively, when the spray device 100 of the washing machine includes at least two spray devices 100 arranged vertically, the transmission device 200 is disposed between the at least two spray devices 100. When there are at least two spray devices 100, the different spray devices 100 can be distributed on both sides of the transmission device 200, thereby providing comprehensive spray cleaning of the tableware and / or kitchenware.

[0091] In addition to the aforementioned components, the cleaning machine may also include other supporting parts, such as a water cup 810, an inlet solenoid valve 830, and a drain pump 840. The water cup 810 can be positioned below at least one of the spray device 100 and the transmission device 200 to handle the fluid generated during the operation of the cleaning machine. Throughout the entire operating cycle of the cleaning machine, the drain pump 840 can periodically open a predetermined number of times to drain the water from the water cup 810. The inlet solenoid valve 830 can be used to control the connection between the external water source and the cleaning machine. When the cleaning machine is equipped with a water softening module 820, the water softening module 820 can be positioned downstream of the inlet solenoid valve 830. When the inlet solenoid valve 830 is open, external water can enter the water softening module 820 for softening treatment, and the softened water can then be supplied to the water cup 810. When the (washing) pump 700 is turned on, it can pump the water in the water cup 810 to the spray device 100 and the transmission device 200.

[0092] Of course, the cleaning machine may also include other functional modules or components, but this application does not make specific limitations on them.

[0093] When tableware and / or kitchenware are placed in the washing machine, the washing machine is started. The tableware and / or kitchenware can rotate intermittently or continuously. The spray device 100 can spray intermittently or continuously. When the spray device 100 is in the intermittent spraying period or in the continuous spraying state, the spray device 100 can rotate or not rotate.

[0094] In this specification, based on the washing machine described in the above embodiments, this application also provides a control method for the washing machine. The control method may include: intermittently adjusting the flow rate of the second flow path 500 to drive the transmission device 200 to intermittently rotate the tableware and / or kitchen utensils; and / or, the electric drive device 300 intermittently drives the transmission device 200 to intermittently rotate the tableware and / or kitchen utensils. The following will describe different embodiments in detail.

[0095] In one embodiment, the tableware and / or kitchen utensils (in a specific embodiment, bowls are used instead) are in an intermittent rotation state, at which time the spray device 100 can be in an indirect spray state.

[0096] Please see Figure 16 The control method may specifically include the following steps: S101. Connect the flow control device 600 to the first flow path 400 only, and spray the tableware and / or kitchenware for a first duration. S103. Connect only the flow control device 600 and the second flow path 500 to drive the transmission device 200 to rotate the tableware and / or kitchenware by a first angle; S105. Repeat S101 and S103 until the total rotation angle of the tableware and / or kitchenware reaches the preset angle.

[0097] In this embodiment, in step S101, the flow control device 600 can be connected only to the first flow path 400. That is, by adjusting the flow control device 600, the fluid is guided to the first flow path 400, thereby allowing the fluid to flow into the spray device 100 to spray and clean the tableware and / or kitchen utensils. Here, the connection can be understood as the flow of fluid in the water path. Physically, the flow control device 600 and the first flow path 400 can always maintain a direct or indirect connection.

[0098] The initial duration can be a preset duration or can be set according to the user's needs. For example, if the user finds the current tableware difficult to clean, the initial duration can be set to be longer; if the user finds the current tableware easy to clean, the initial duration can be set to be shorter.

[0099] After the tableware and / or kitchenware in the current position has been sprayed and cleaned for the first time, a certain area of ​​the tableware and / or kitchenware will be directly rinsed by the water flow, and the cleaning effect of that area will be better. For other areas that are not directly rinsed by the water flow, the position of the tableware and / or kitchenware needs to be adjusted.

[0100] At this point, step S103 can be executed, connecting only the flow control device 600 to the second flow path 500. That is, by adjusting the flow control device 600, the fluid is guided to the second flow path 500, thereby enabling the fluid to drive the transmission device 200 to rotate the tableware and / or kitchenware by a first angle, switching to a new position. Similarly, the meaning of "connected" above can be referred to the specific description in step S101 above, and will not be repeated here.

[0101] The first angle can be a preset angle, and specifically, the first angle can include multiple angles. For example, the dishwasher can automatically match the first angle according to the size of the item being washed. Generally, when the size of the item being washed is large, the first angle can be automatically matched to a smaller angle; when the size of the item being washed is large, the second angle can be automatically matched to a larger angle.

[0102] To achieve the desired cleaning effect, steps S101 and S103 can be repeated until the total rotation angle of the tableware and / or kitchenware reaches the preset angle. At this point, the tableware and / or kitchenware can be cleaned with a direct spray of water for full coverage.

[0103] Specifically, taking a dishwasher as an example, this cleaning machine periodically rotates the bowls during the washing process, ensuring each surface is alternately exposed to the direct water jet. This shortens the washing time while maintaining the same cleaning effect, meaning better cleaning results can be achieved within the same washing time. Furthermore, experimental verification shows that under the same conditions, rotating the bowls allows for alternating direct water flow to all soiled surfaces, potentially reducing washing time by up to 50%. Moreover, in steps S101 and S103, the fluid pressure is concentrated only in the first flow path 400 for cleaning and only in the second flow path 500 to provide rotational power. At different stages, this optimizes the cleaning effect and maximizes the reliability of the rotating objects, achieving a better match between cleaning and rotation, thus ensuring rapid cleaning. Additionally, it avoids wear and tear that might occur from continuous rotation of tableware and / or kitchen utensils. In some operating conditions, for tableware and / or kitchenware that are heavy and have residues that are difficult to clean, this control method can ensure the cleaning effect through powerful cleaning and stable rotation. It should be noted that the above is only an example of one operating condition, and this control method is also applicable to other operating conditions.

[0104] Furthermore, in order to ensure that the cleaning machine can efficiently and comprehensively clean tableware and / or kitchenware without dead angles, the spray device 100 rotates and sprays, and within at least two rotation cycles, at least the same spray nozzle on the spray device 100 sprays at least partially different areas on the same tableware and / or kitchenware.

[0105] The two rotation cycles can be adjacent or non-adjacent, depending on the specific cleaning mode. The cleaning machine can include multiple cleaning modes, such as a first cleaning mode and a second cleaning mode. The first cleaning mode is for cleaning difficult-to-clean tableware and / or kitchenware, while the second cleaning mode is for cleaning relatively easy-to-clean tableware and / or kitchenware. In the first cleaning mode, the same area can be repeatedly sprayed with direct airflow. After completely rinsing an area, the tableware and / or kitchenware are rotated at a certain angle and sprayed again. In the second cleaning mode, the same area can be sprayed with direct airflow once, and then the tableware and / or kitchenware are rotated at a certain angle and sprayed again. The cleaning areas corresponding to adjacent direct airflows do not need to completely overlap.

[0106] In another embodiment, the tableware and / or kitchen utensils are in an intermittent rotation state, during which the spray device 100 can be in a continuous spray state. Specifically, when the washing machine is washing the tableware and / or kitchen utensils, the flow control device 600 is always connected to the first flow path 400, so that the spray device 100 is always in a spray state.

[0107] To achieve the above functions, the control method corresponding to this cleaning machine is as follows: The first flow path 400 is kept in constant communication with the flow control device 600, ensuring continuous spraying and cleaning of the tableware and / or kitchenware. Simultaneously, the flow rate of the second flow path 500 is intermittently adjusted by the flow control device 600, driving the transmission device 200 to intermittently rotate the tableware and / or kitchenware by a first angle until the total rotation angle of the tableware and / or kitchenware reaches a preset angle. Through the control method of this embodiment, while ensuring the rotation of the tableware and / or kitchenware, the tableware and / or kitchenware can always be sprayed by the spray device. Especially when the pump 700 has sufficient capacity, continuous spraying by the spray device 100 can more effectively wash the tableware and / or kitchenware, thereby improving pump utilization and maximizing energy utilization. In addition, controlling the intermittent rotation of tableware and / or kitchen utensils can also avoid wear and tear that may be caused by continuous rotation. In some usage conditions, for some lighter tableware and / or kitchen utensils, this control method can ensure cleaning effect while taking into account rotation. It should be noted that the above is only an example of one usage condition, and this control method is also applicable to other usage conditions.

[0108] Please refer to the following: Figure 17 In one specific implementation, taking a dishwasher as an example, when the dishwasher is turned on, the water inlet solenoid valve 830 is opened first to fill water; then the pump 700 is started to connect the first flow path 400 to spray and rinse the bowl; then the flow control device 600 is adjusted to connect the second flow path 500 to make the bowl rotate for N seconds.

[0109] It should be noted here that adjusting the operation of the flow control device 600 can completely switch the first flow path 400 to the second flow path 500, causing the spray device 100 to stop spraying; or, it can keep the first flow path 400 flowing through, allowing the spray device 100 to spray continuously.

[0110] After the bowl has rotated for N seconds, the second flow path 500 can be disconnected and the first flow path 400 can be reconnected by adjusting the flow control device 600, or the first flow path 400 can be kept connected, so that the bowl after rotating through the first angle can be sprayed and cleaned.

[0111] Determine if the bowl has rotated P times. If the bowl has not rotated P times, repeat the above steps until the bowl rotates P times, then drain the water. At this point, the dishwasher has completed the washing process.

[0112] The number of rotations P can be a preset minimum number of rotations to ensure that every soiled surface of the tableware and / or kitchenware is rinsed directly under the water flow during the washing process. When the single rotation time N is combined with the total number of rotations P, it is used to ensure that the bowl rotates at least X degrees during the washing process.

[0113] Please refer to the following: Figure 18 In another specific implementation, taking a dishwasher as an example, after the dishwasher is turned on, the water inlet solenoid valve 830 is first opened to fill with water; then the pump 700 is started, connecting the first flow path 400 to spray and rinse the bowls. The difference between this implementation and the above is that the first flow path 400 is always connected to the pump 700, and the spray device 100 can continuously spray the bowls. Subsequently, by adjusting the flow control device 600, the second flow path 500 is connected, causing the bowls to rotate for N seconds. Then the second flow path 500 is disconnected, causing the bowls to rotate intermittently.

[0114] Determine if the bowl has rotated P times. If the bowl has not rotated P times, repeat the above steps until the bowl rotates P times, then drain the water. At this point, the dishwasher has completed the washing process.

[0115] When the drive device 300 causes the transmission device 200 to rotate the tableware and / or kitchenware intermittently, the rotation of the tableware and / or kitchenware allows different parts of the tableware and / or kitchenware to be cleaned when the spray device 100 is in the same position, thereby increasing the cleaning coverage. At the same time, when the spray device 100 and the drive device 300 share the same pump 700, the pressure of the pump 700 can be concentrated on cleaning the tableware and / or kitchenware that has stopped rotating during the intervals when the tableware and / or kitchenware stops rotating, further ensuring the cleaning effect.

[0116] In other embodiments, the tableware and / or kitchen utensils may be in a rotating state during the washing process, in which case the spray device 100 may be in a continuous spraying state or an intermittent spraying state.

[0117] Specifically, when the first flow path 400 is always connected to the flow control device 600 so that the spray device 100 is always spraying, or when it is intermittently connected so that the spray device 100 sprays intermittently, the flow rate of the second flow path 500 is controlled by the flow control device 600, so that the fluid flowing through the second flow path 500 drives the transmission device 200 to keep the tableware and / or kitchenware rotating, and / or, the transmission device 200 is always driven to rotate by the electric drive device 300 so that the tableware and / or kitchenware keep rotating.

[0118] The control method of making the tableware and / or kitchen utensils rotate continuously and the spray device spray intermittently can ensure the rotation effect of the tableware and / or kitchen utensils to a large extent. In particular, during the intermittent spraying of the spray device, the reliability of the rotation of the tableware and / or kitchen utensils can be further improved.

[0119] In a specific scenario, for tableware and / or kitchenware that are relatively easy to clean, the washing machine can be equipped with a quick cleaning mode. When this quick cleaning mode is activated, the tableware and / or kitchenware are constantly rotating, and the spray device 100 is constantly spraying, thereby achieving efficient and rapid cleaning of the relatively easy-to-clean tableware and / or kitchenware, thus meeting the user's current usage needs.

[0120] In another specific scenario, when tableware and / or kitchenware are difficult to clean, especially when dried food residue adheres to them, the washing machine can be equipped with a deep cleaning mode. When this deep cleaning mode is activated, the tableware and / or kitchenware remain in a rotating state, and the spray device 100 can be controlled to spray intermittently. For example, an initial spray of a certain duration can be performed to wet the tableware and / or kitchenware, followed by multiple intermittent sprays. This effectively cleans the dried food residue through the combined action of soaking and spraying, thus completing the cleaning task for tableware and / or kitchenware that is particularly difficult to clean. To ensure that the fluid sprayed by the spray device 100 can be sprayed directly onto every area of ​​the tableware and / or kitchenware without any blind spots, when the first flow path 400 and the flow control device 600 are always connected so that the spray device 100 is always in a spraying state, the spray device 100 is in a rotating state and the angular velocity of the spray device 100 is different from the angular velocity of the tableware and / or kitchenware rotating under the drive of the transmission device 200.

[0121] If the spray device 100 has the same angular velocity as the tableware and / or kitchenware, the spray liquid sprayed by the spray device 100 when it rotates to the designated position may repeatedly spray the same area of ​​the tableware and / or kitchenware, which will not only waste energy, but also fail to achieve the desired cleaning effect.

[0122] To ensure that the spray liquid from the rotating spray device 100 reaches different areas of the tableware and / or kitchenware at designated locations (i.e., the point of contact between the spray liquid and the tableware and / or kitchenware changes), the angular velocity of the spray device 100 can be controlled to differ from the angular velocity of the tableware and / or kitchenware. This difference in angular velocity creates a speed difference, which allows for better matching between the spray from the spray device 100 and the rotation of the tableware and / or kitchenware, thereby achieving comprehensive cleaning of every area of ​​the tableware and / or kitchenware.

[0123] Furthermore, to ensure that the cleaning machine can more efficiently and comprehensively clean tableware and / or kitchenware without any blind spots, the spray device 100 rotates and sprays, and within at least two rotation cycles, at least the same spray nozzle on the spray device 100 sprays at least partially different areas on the same tableware and / or kitchenware. These two rotation cycles can be adjacent or non-adjacent, and can be specifically set according to the actual cleaning mode, etc., which is not specifically limited herein.

[0124] 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.
