Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the washing machine technology. More particularly, a washing machine, a control method of the washing machine, a storage medium and a program product are disclosed. BACKGROUND

[0002] In the use of the washing machine, the impurities such as mud, dust and stains carried by the clothes are mixed into the washing water. In addition, the clothes are continuously impacted by the water flow force, mechanical force, mutual friction force between the clothes and the detergent in the washing process, so that the fibers of the clothes are abraded and broken to generate lint, which is also mixed into the washing water. As a result, the clothes are always washed in the washing water mixed with various impurities, and the washing cleanliness is reduced.

[0003] In the prior art, a power water pump and a filter are added in the washing machine to realize the recycling of the filtered washing water to the washing drum. At present, one power water pump is used to control the washing water circulation and drainage, but the rotation speed for controlling the washing water circulation and the rotation speed for controlling the drainage are both constant, the operation power is not matched, the filtering efficiency is low, and the power consumption is increased. SUMMARY

[0004] Embodiments of the present application provide a washing machine, a control method of the washing machine, a storage medium and a program product, which can improve the filtering efficiency of the impurities in the washing water and reduce the power consumption.

[0005] In a first aspect, embodiments of the present application provide a washing machine, which comprises:

[0006] a cabinet;

[0007] an outer drum installed in the cabinet;

[0008] an inner drum rotatably arranged in the outer drum and used for loading clothes;

[0009] a driving motor connected to the inner drum and used for driving the rotation of the inner drum to clean the clothes in the inner drum;

[0010] a pump housing configured to form a filtering cavity and a water inlet cavity, wherein the pump housing is provided with a water inlet, a circulation inlet, a circulation outlet, a water passage, a bypass pipeline and a drainage outlet;

[0011] a filter arranged in the filtering cavity and located between the water passage and the circulation outlet, and used for filtering the impurities in the washing water;

[0012] the water inlet is connected to the outer drum and the water inlet cavity;

[0013] the circulation inlet is connected to the water inlet cavity and the bypass pipeline;

[0014] The water inlet connects the bypass pipe to the filter chamber;

[0015] The circulation outlet connects the filter chamber to the outer cylinder;

[0016] The water inlet, the water inlet chamber, the circulation inlet, the bypass pipe, the water outlet, the filter chamber, the filter, and the circulation outlet form a circulating water channel;

[0017] The drain outlet is connected to the water inlet chamber;

[0018] The drain outlet, the water inlet cavity, and the water inlet together form a drainage channel;

[0019] A power pump is used to drive the washing water in the outer drum back to the outer drum through the circulating water channel during the washing stage, and to drive the washing water in the outer drum to be discharged to the outside of the outer drum through the drain channel during the spin-drying stage.

[0020] The control unit connected to the power pump is configured to:

[0021] During the laundry washing stage, determine the rotational speed associated with that stage.

[0022] The operation of the power pump is controlled by the stated rotational speed.

[0023] The washing machine provided in this embodiment circulates the washing water during the washing stage and drains the water during the spin-drying stage. This allows for both washing water circulation and drainage using a single pump, eliminating the need for multiple pumps for different scenarios, thus improving pump utilization and simplifying the washing machine's structure. Furthermore, by incorporating a filter, impurities are trapped inside the filter after the washing water enters the pump casing, and the filtered washing water flows back to the outer drum, achieving washing water circulation and improving circulation efficiency.

[0024] Secondly, by determining the corresponding speed of the power pump based on different stages of garment washing, the same power pump can operate at variable speeds during water circulation and spin-drying, not limited to a constant speed, thus meeting the operational needs of different stages. That is, the content of impurities in the clothes and the required water flow intensity vary at different stages of garment washing. By adjusting the power pump speed, impurities are filtered efficiently while reducing wear and tear on the clothes during washing. Therefore, this embodiment improves filtration efficiency, thereby enhancing washing quality and improving the cleaning effect on clothes. Simultaneously, it reduces power consumption and improves the performance of the washing machine.

[0025] In some embodiments of this application, the control unit is configured as follows:

[0026] During the washing phase, the power pump is controlled to drive at a first rotational speed;

[0027] After running for a first preset time, the power pump is controlled to drive at a second speed, which is less than the first speed.

[0028] The washing machine provided in this embodiment controls the power pump to operate at a first speed during the washing stage, and then switches to a second speed after running for a period of time to reduce the speed. Since clothes carry a large amount of impurities at the beginning of the wash cycle, setting the first speed higher than the second speed allows for rapid filtration of a large amount of impurities, improving filtration efficiency and ensuring washing results. Subsequently, reducing the speed after running at the first speed for a period ensures filtration effectiveness, meeting the needs of different washing stages while simultaneously saving energy and extending the washing machine's lifespan.

[0029] In some embodiments of this application, the control unit is configured as follows:

[0030] After controlling the power pump to run at the second speed for a second preset time, if the washing time has not reached the preset washing end threshold indicated by the washing stage, the operation of the power pump is stopped, and after a preset delay time, the power pump is controlled to run at the second speed again until the washing time reaches the preset washing end threshold.

[0031] The washing machine provided in this embodiment ensures the cleanliness of the wash water during the washing process by triggering the restart of the power pump at a second speed when the washing time has not reached the preset washing end threshold, until the washing stage ends. This embodiment eliminates the need for continuous operation of the power pump, achieving continuous purification of the wash water during the washing process, while reducing unnecessary consumption, saving energy, reducing the operating burden on the power pump, and extending the service life of the washing machine.

[0032] In some embodiments of this application, the control unit is configured as follows:

[0033] During the clothes washing stage, the power loss of the drive motor during the driving process is obtained;

[0034] Calculate the weight of the clothes in the inner drum based on the power loss.

[0035] Based on the weight of the clothing, the relevant rotation speed is determined, and the power pump is controlled to operate according to the rotation speed.

[0036] The washing machine provided in this embodiment determines the weight of the clothes in the inner drum by acquiring the power loss of the drive motor. This allows for the determination of the rotation speed for different washing stages based on the varying weights of the clothes, ensuring that the water flow speed matches the weight of the clothes. In other words, different weights of clothes correspond to different water flows, preventing excessive wear and tear on the clothes. Simultaneously, controlling the speed of the power pump based on the weight of the clothes ensures effective washing while maintaining a reasonable energy consumption range, avoiding unnecessary energy waste.

[0037] In some embodiments of this application, the control unit is configured as follows:

[0038] During the washing stage, if the weight of the clothes does not reach the preset weight threshold, the power pump is controlled to run at a third speed, or if the weight of the clothes reaches the preset weight threshold, the power pump is controlled to run at a fourth speed, the fourth speed being greater than the third speed.

[0039] The washing machine provided in this embodiment controls the power pump to operate at a third speed when the clothes are relatively light and at a fourth speed when the clothes are relatively heavy. The fourth speed is greater than the third speed, allowing heavier clothes to be washed at a higher speed, thus improving the efficiency of water circulation and consequently increasing the filtration efficiency of impurities.

[0040] In some embodiments of this application, the control unit is configured as follows:

[0041] During the rinsing stage, if the weight of the clothes has not reached the preset weight threshold, the power pump is controlled to run at a fifth speed, or if the weight of the clothes has reached the preset weight threshold, the power pump is controlled to run at a sixth speed, where the sixth speed is greater than the fifth speed.

[0042] The washing machine provided in this embodiment controls the power pump to operate at a fifth speed when the clothes are relatively light during the rinsing stage, and at a sixth speed when the clothes are relatively heavy. The sixth speed is higher than the fifth speed, allowing heavier clothes to be rinsed at a higher speed, thus improving the efficiency of the washing water circulation and consequently increasing the filtration efficiency of impurities.

[0067] In some embodiments of this application, the method includes:

[0068] During the clothes washing stage, the power loss of the drive motor during the driving process is obtained;

[0069] Calculate the weight of the clothes in the inner drum based on the power loss.

[0071] In some embodiments of this application, the method includes:

[0072] During the washing stage, if the weight of the clothes does not reach the preset weight threshold, the power pump is controlled to run at a third speed, or if the weight of the clothes reaches the preset weight threshold, the power pump is controlled to run at a fourth speed, the fourth speed being greater than the third speed.

[0073] In some embodiments of this application, the method includes:

[0080] The washing machine, its control method, storage medium, and program product provided in this application embodiment achieve washing water circulation by controlling a power pump during washing and drainage during spin-drying.

[0098] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0099] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0100] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0101] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0102] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0103] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0104] In existing technologies, during the use of a washing machine, impurities such as mud, dust, and stains carried by the clothes themselves will mix into the washing water. Furthermore, during the washing process, the clothes are constantly subjected to the combined effects of water flow, mechanical force, friction between garments, and detergent, causing the fabric fibers to wear and break, producing lint that also mixes into the washing water. This results in the clothes being washed in a mixture of various impurities, leading to a decrease in the cleanliness of the wash.

[0105] Currently, by adding a power pump and a filter to the washing machine, the washed water is filtered and circulated back into the washing drum. A single power pump controls both the water circulation and drainage; however, both the water circulation and drainage speeds are constant, resulting in a power mismatch that leads to low filtration efficiency and increased power consumption.

[0106] Based on the above problems, this application determines the corresponding speed of the power pump according to different clothing washing stages, so that the operation of the power pump is controlled by the speed, and the speed can be changed during the washing water circulation process, not limited to a constant speed, which meets the operating needs of different clothing washing stages, improves filtration efficiency, and reduces power consumption.

[0107] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0108] It should be noted that the solution in this application is not only applicable to washing machines with power pumps.

[0109] The following description uses a washing machine with a power pump as an example to illustrate the solution of this application.

[0110] Combination Figure 1 The washing machine includes a cabinet 100, which serves as the main carrier of the washing machine. It is used to install internal washing components, water inlet and drainage components, etc., and also to support the washing machine on the ground.

[0111] To maximize the use of space, the washing machine casing 100 is typically cubic in shape, for example, with... Figure 1 The cuboid shown in the image.

[0112] The container 100 is provided with a dispensing opening (not shown in the attached drawing) for dispensing or retrieving laundry items into the container. The container 100 is provided with a door (not shown in the attached drawing) capable of opening or closing the dispensing opening. One side of the door is hinged to the container 100 via a hinge assembly, allowing the door to rotate relative to the container 100 to open or close the dispensing opening.

[0113] In some embodiments, the door includes a glass door panel so that the user can observe the washing status through the glass door panel.

[0114] The washing machine in this embodiment of the application also includes an outer tub 210, which is installed inside the housing 100 and is used to store washing water; and the opening of the outer tub 210 faces the inlet.

[0115] In some embodiments, the bottom of the outer cylinder 210 is connected to the bottom plate 110 of the housing 100 via a shock absorber, and the top of the outer cylinder 210 is connected to the top of the housing 100 via a hanging spring, which helps to reduce the vibration of the outer cylinder 210.

[0116] The washing machine in this embodiment of the application also includes an inner drum 220, which is rotatably installed inside the outer drum 210, with the opening of the inner drum 220 facing the loading port.

[0117] A drive motor, connected to the inner drum 220, is used to drive the rotation of the inner drum 220 to wash the clothes in the inner drum 220.

[0118] During the washing process, the inner drum 220 contains laundry, and multiple small holes are arranged on the inner drum 220 to connect it with the outer drum 210. Washing water in the outer drum 210 enters the inner drum 220 through the small holes. The inner drum 220 rotates relative to the outer drum 210 to clean the laundry. After washing, the water in the outer drum 210 is discharged through the drain component.

[0119] In this embodiment, the washing machine also includes a door seal, which is disposed between the opening of the outer drum 210, the housing 100, and the door to seal the gap between the door and the opening of the outer drum 210. This can improve the sealing between the door and the outer drum 210, reduce the possibility of washing water flowing out from the gap between the door and the outer drum 210, and improve the reliability and stability of the washing machine.

[0120] Continue to refer to Figure 1 The washing machine in this embodiment of the application also includes a pump assembly 300, which is configured to extract washing water from the outer drum 210 and circulate it back to the outer drum 210 or to discharge washing water from the outer drum 210 to the outside of the outer drum 210.

[0121] It should be noted that the outer cylinder 210 serves as a water-holding cylinder, and the inner cylinder 220 is connected to the outer cylinder 210 through a small hole in its side wall. When the pump assembly 300 circulates the washing water back to the inner cylinder 220, it is also considered to circulate the washing water back to the outer cylinder 210.

[0122] The pump assembly 300 is connected to the outer cylinder 210. Specifically, the pump assembly 300 is connected to the outer cylinder 210 through the connecting pipe 510 and the circulation pipe 520.

[0123] In some embodiments, one end of the connecting pipe 510 is connected to the bottom of the outer cylinder 210, so as to facilitate the drainage of water in the outer cylinder 210 as much as possible; the other end of the connecting pipe 510 is connected to the water inlet of the pump assembly 300, so as to transport water in the outer cylinder 210 to the pump assembly 300.

[0124] In some embodiments, the connecting pipe 510 is arranged parallel to the bottom plate 110 of the housing 100, which facilitates the discharge of water from the outer drum 210 to the pump assembly 300 and also improves the compactness of the washing machine structure.

[0125] In some embodiments of this application, the connecting pipe 510 can be a rigid pipe for easy fixing; or, the connecting pipe 510 can be a flexible hose, such as a corrugated pipe, which can extend or deform and has a flexible connection position.

[0126] In some embodiments, one end of the circulation pipe 520 is connected to the outlet of the pump assembly 300, and the other end of the circulation pipe 520 is connected to the top of the outer cylinder 210, so as to re-transport the water in the pump assembly 300 back into the outer cylinder 210.

[0127] In some embodiments of this application, the other end of the circulation pipe 520 is connected to the door seal, thereby directly transporting the washing water back to the inner drum 220 and indirectly circulating the washing water to the outer drum 210. A spray structure can be provided on the door seal, and the circulation pipe 520 is used to supply water to the spray structure. The spray structure is configured to spray towards the laundry inside the inner drum 220 to improve the washing effect.

[0128] The circulation pipe 520 can be a rigid pipe for easy fixing; or the circulation pipe 520 can be a flexible pipe, such as a corrugated pipe, which can be stretched or deformed and has a flexible connection position.

[0129] Of course, the pump assembly 300 is also connected to a drain pipe to drain the washing water from the washing machine after the wash cycle is complete.

[0130] In some embodiments of this application, a filter is provided inside the pump assembly 300 so that the washing water entering the pump assembly 300 flows through the filter and is discharged from the pump assembly 300. In other words, the washing water entering the pump assembly 300 will be filtered by the filter and then circulated back to the outer drum 210 or discharged to the outside of the washing machine to improve the filtration effect.

[0131] The structure of a filter can vary, such as a cylindrical filter or a sheet filter.

[0132] The following description, in conjunction with the accompanying drawings, details the flow direction of the washing water within the pump assembly 300 and the specific structure of the filter in the embodiments of this application.

[0133] like Figure 2 As shown, the pump assembly 300 includes a pump housing 310, which is fixed inside the housing 100. For example, a mounting base 340 is provided on the pump housing 310 and is fixed to the base plate 110 of the housing 100. For instance, the mounting base 340 is fixed to the base plate 110 with screws, providing a stable and reliable connection.

[0134] In some embodiments of this application, the pump housing 310 is a long strip structure and is not installed vertically. For example, the pump housing 310 is installed parallel to the bottom plate 110 of the casing 100, which can reduce the space occupied by the pump housing 310 in the height direction, so that the pump housing 310 can be adapted to the small height space at the bottom of the outer drum 210, thereby improving the compactness of the washing machine structure.

[0135] In some embodiments, the pump housing 310 has a circular cross-section and is constructed to form a cylindrical chamber with openings at both ends, which facilitates the installation of the internal structure.

[0136] In some embodiments, the pump assembly 300 further includes a plug 330, which is installed at one end opening of the pump housing 310 to seal the opening. Furthermore, the plug 330 is detachably connected to the pump housing 310, facilitating the removal of the plug 330 to clean the internal filter of the pump housing 310.

[0137] There are several ways to detachably connect the plug 330 and the pump housing 310. For example, the plug 330 and the pump housing 310 are connected by a thread; another example is that the plug 330 and the pump housing 310 are snap-fitted together; yet another example is that the plug 330 is provided with an arc-shaped groove extending around its circumference, and the pump housing 310 is provided with a protrusion. Through the cooperation of the protrusion and the arc-shaped groove, the plug 330 and the pump housing 310 are detachably connected, and the connection is stable and reliable. The plug 330 can be disassembled and installed by rotating relative to the pump housing 310, making disassembly and assembly simple and convenient.

[0138] In some embodiments of this application, a cover plate is provided on the bottom side of the front panel of the housing 100. After the cover plate is opened, the plug 330 is exposed, so that the plug 330 and the subsequent filter cartridge 410 can be disassembled for cleaning, which is convenient for disassembly.

[0139] In some embodiments, the pump assembly 300 further includes a power pump 320, which serves as a power component for driving the washing water to flow within the pump housing 310 and is installed at the other end opening of the pump housing 310. Thus, the pump housing 310, the plug 330, and the power pump 320 together enclose and form a water flow channel.

[0140] Continue to refer to Figure 1 and Figure 2 In some embodiments, a water inlet 304 is formed on the pump housing 310, which is connected to the connecting pipe 510 and is configured to deliver washing water into the pump housing 310.

[0141] In some embodiments, the pump casing 310 is provided with a water inlet chamber, which is connected to the water inlet 304 and is used to store the washing water that enters the pump casing from the outer cylinder.

[0142] A circulation outlet 305 is also formed on the pump casing 310. The circulation outlet 305 is connected to the circulation pipe 520, and the washing water in the pump casing 310 enters the circulation pipe 520 through the circulation outlet 305.

[0143] A drain outlet 306 is formed on the pump housing 310. The drain outlet 306 is configured to communicate with the drain pipe of the washing machine, and the washing water inside the pump housing 310 is discharged through the drain outlet 306.

[0144] The drain outlet, the inlet chamber, and the inlet form a drainage channel.

[0145] In some embodiments, the pump housing 310 has three pipe joints, one of which is configured to form an inlet 304, another is configured to form a circulation outlet 305, and yet another is configured to form a drain outlet 306. This arrangement facilitates the connection of the inlet 304 to the connecting pipe 510, the circulation outlet 305 to the circulation pipe 520, and the drain outlet 306 to the drain pipe.

[0146] Combination Figure 3 and Figure 4 In some embodiments of this application, the pump housing 310 is configured to form a filter chamber 301 and a water inlet chamber. A filter 400 is installed in the filter chamber 301 to filter the washing water entering the filter chamber 301. The water inlet chamber is connected to a water inlet 304 and is used to store the washing water entering the pump housing from the outer cylinder. The water inlet 304 is connected to the filter chamber 301, so that the washing water can enter the filter chamber 301 through the water inlet 304.

[0147] In some embodiments of this application, the pump housing 310 is further provided with a circulation bypass pipe and a bypass port. The bypass pipe is used to transport washing water. The circulation inlet connects the water inlet chamber and the bypass pipe to guide the washing water in the water inlet chamber into the bypass pipe. The bypass port connects the bypass pipe and the filter chamber to allow the washing water to enter the filter chamber from the bypass pipe.

[0148] In this embodiment, the inlet, inlet chamber, circulation inlet, bypass pipe, outlet, filter chamber, filter, and circulation outlet form a circulating water channel.

[0149] In this embodiment, the filter 400 is a filter cartridge 410, which is cylindrical.

[0150] The filter cartridge 410 includes a cartridge body 411, which is cylindrical. Multiple filter holes are evenly arranged on the cartridge body 411 to allow washing water to pass through.

[0151] One end of the cylindrical body 411 is open, forming the water inlet side of the filter cylinder 410; one side of the outer surface of the cylindrical body 411 forms the water outlet side of the filter cylinder 410. Thus, the washing water in the filter chamber 301 enters the interior of the cylindrical body 411 through the opening, and then flows through the filter holes to the outside of the cylindrical body 411, while impurities remain inside the cylindrical body 411. A gap exists between the outer surface of the cylindrical body 411 and the inner wall of the pump housing 310 to facilitate the discharge of filtered water.

[0152] The filter cartridge 410 also includes a connecting seat 412, which is connected to the end of the cartridge body 411 opposite to its water inlet side. For example, the connecting seat 412 and the cartridge body 411 are integrally formed parts.

[0153] The connecting seat 412 not only seals one end of the filter cartridge 411, but also connects to the plug 330. Thus, when the plug 330 is removed from the pump housing 310, the filter cartridge 410 can be detached from the pump housing 310 together with the plug 330, thereby enabling the cleaning of impurities inside the filter cartridge 410.

[0154] There are several ways to connect the plug 330 and the connecting seat 412. For example, the plug 330 and the connecting seat 412 can be snapped together, or the plug 330 and the connecting seat 412 can be threaded together.

[0155] Continue to refer to Figure 3 and Figure 4 In this embodiment, an impeller cavity 302 is also formed inside the pump casing 310, and the impeller cavity 302 is connected to the circulation outlet 305 and the drain outlet 306 respectively.

[0156] The power pump 320 of this application embodiment includes an impeller 321, which is located in the impeller cavity 302.

[0157] The power pump 320 of this embodiment also includes a motor 322, which is mounted on the pump housing 310. For example, the motor 322 is fixed to the pump housing 310 with screws, providing a reliable fixing method.

[0158] Motor 322 is connected to impeller 321, and motor 322 is configured to drive impeller 321 to rotate clockwise or counterclockwise. Motor 322 can be a brushless direct current motor (BLDCM).

[0159] When the motor 322 drives the impeller 321 to rotate clockwise, the washing water in the impeller cavity 302 is discharged to the outside of the pump casing 310 through the circulation outlet 305; when the motor 322 drives the impeller 321 to rotate counterclockwise, the washing water in the impeller cavity 302 is discharged to the outside of the pump casing 310 through the drain outlet 306.

[0160] Of course, when the motor 322 drives the impeller 321 to rotate counterclockwise, the washing water in the impeller cavity 302 is discharged to the outside of the pump casing 310 through the circulation outlet 305; when the motor 322 drives the impeller 321 to rotate clockwise, the washing water in the impeller cavity 302 is discharged to the outside of the pump casing 310 through the drain outlet 306.

[0161] Thus, the flow path of the washing water during circulation is as follows:

[0162] Motor 322 drives impeller 321 to rotate clockwise. Washing water in outer cylinder 210 enters filter chamber 301 through connecting pipe 510 and water inlet 304, and then enters filter cylinder 410 through opening. Impurities are filtered inside filter cylinder 410. Washing water flows through filter holes of filter cylinder 410 to the gap between filter cylinder 410 and pump housing 310. Then it enters impeller chamber 302 through water passage 303, and returns to outer cylinder 210 through circulation outlet 305 and circulation pipe 520 to wash the laundry.

[0163] This embodiment of the application purifies the washing water by filtering it and circulating it back into the outer drum 210, thereby reducing repeated contamination of clothes by the washing water, reducing the number of rinsing cycles and the time required, reducing the amount of lint and impurities adhering to the surface of the clothes after washing, improving the washing effect, and thus enhancing the washing quality.

[0164] The flow path of the washing water when it is discharged is as follows:

[0165] Motor 322 drives impeller 321 to rotate counterclockwise. Washing water in outer drum 210 enters filter chamber 301 through connecting pipe 510 and water inlet 304, and then enters filter cylinder 410 through opening. Impurities are filtered inside filter cylinder 410. Washing water flows through filter holes of filter cylinder 410 to the gap between filter cylinder 410 and pump housing 310. Then it enters impeller chamber 302 through water passage and is discharged into drain pipe through drain outlet 306, and finally discharged to the outside of washing machine.

[0166] Therefore, the washing water follows the same path before entering the impeller cavity 302, whether it is draining or circulating. In other words, both draining and circulating water need to be filtered by the filter cartridge 410, resulting in good filtration. Moreover, the washing water enters the water passage 303 through the inlet side of the filter cartridge 410 and then through the outlet side, ensuring that all the washing water is filtered by the filter cartridge 410 before being discharged, which helps to improve the filtration effect.

[0167] The following explanation uses the control unit of a washing machine as an example to illustrate the control method of a washing machine. The following specific embodiments can be combined with each other, and some embodiments will not elaborate on the same or similar concepts or processes.

[0168] Figure 5 This is a flowchart illustrating a control method for a washing machine provided in an embodiment of this application. Figure 5 As shown, this method is applied to the control unit of a washing machine.

[0169] It should be noted that the washing machine includes: a cabinet; an outer drum installed inside the cabinet; an inner drum rotatably disposed inside the outer drum for loading clothes; a drive motor connected to the inner drum for driving the rotation of the inner drum to wash the clothes in the inner drum; a pump housing configured to form a filter chamber and a water inlet chamber, the pump housing being provided with a water inlet, a circulation inlet, a circulation outlet, a water outlet, a bypass pipe, and a drain outlet; and a filter disposed inside the filter chamber, and the filter being located between the water outlet and the circulation outlet for filtering impurities in the washing water.

[0170] The water inlet connects the outer cylinder to the water inlet chamber; the circulation inlet connects the water inlet chamber to the bypass pipe; the water outlet connects the bypass pipe to the filter chamber; and the circulation outlet connects the filter chamber to the outer cylinder. The water inlet, water inlet chamber, circulation inlet, bypass pipe, water outlet, filter chamber, filter, and circulation outlet form a circulating water channel. The drain outlet connects to the water inlet chamber; the drain outlet, water inlet chamber, and water inlet form a drain channel.

[0171] A power pump is used to drive the washing water in the outer drum back to the outer drum through the circulating water channel during the washing stage, and to drive the washing water in the outer drum to be discharged to the outside of the outer drum through the drain channel during the spin-drying stage.

[0172] Specifically, the method includes the following steps S601 to S602.

[0173] S601. During the clothes washing stage, determine the rotation speed related to the clothes washing stage.

[0174] In some embodiments, a single power pump is used for both circulation and drainage to reduce costs. The power pump includes a motor, a pump casing, and an impeller housed within the pump casing. The motor drives the impeller to rotate. The pump casing has a drain port and a circulation port, and a filter is installed inside the pump casing. When drainage is required, the motor drives the impeller to rotate in a first direction, thereby discharging water from the pump casing through the drain port. When circulating water is required, the motor drives the impeller to rotate in a second direction, thereby discharging water from the pump casing back into the inner cylinder through the circulation port. Wherein, when the first direction is clockwise, the second direction is counterclockwise; and when the first direction is counterclockwise, the second direction is clockwise.

[0175] It should be noted that the rotation speed during the garment washing stage in this application is not constant. Unlike existing technologies where the power pump drives the washing water circulation at a constant speed, this application determines the corresponding rotation speed based on the garment washing stage and any time period within any washing stage. This controls the rotation of the power pump, meeting the operational needs of different scenarios, achieving efficient filtration of impurities, and improving the efficiency of washing water circulation. Simultaneously, it avoids the power mismatch caused by a constant rotation speed in existing technologies, thus reducing power consumption.

[0176] In this application, the garment washing stage is used to indicate the washing of garments in the inner drum. The garment washing stage can be a washing stage or a rinsing stage, with different washing stages corresponding to different rotation speeds. Optionally, during the washing or rinsing stage, the corresponding washing mode can be adapted based on parameters such as the weight and fabric type of the garments. For example, the washing stage corresponds to rotation speed 1, and the rinsing stage corresponds to rotation speed 2, where rotation speed 1 can be different from rotation speed 2. Since there are more impurities (such as impurities carried by the garments themselves) in the washing stage than in the rinsing stage, the rotation speed 1 of the washing stage can be set to be greater than the rotation speed 2 of the rinsing stage; for example, rotation speed 1 is 3000 r / min, and rotation speed 2 is 1000 r / min.

[0177] Optionally, the rotation speed corresponding to any time period in any washing stage can be the same as the rotation speed corresponding to other washing stages. For example, since the clothes carry a large amount of debris at the beginning of the washing stage, the power pump operates at speed 1. After a period of washing, the debris content in the clothes and wash water decreases, and the rotation speed can be reduced to speed 3. The speed 3 corresponding to the current time period in the washing stage can be the same as the speed 2 corresponding to the rinsing stage, achieving energy saving and consumption reduction.

[0178] S602. Control the operation of the power pump at the specified rotational speed.

[0179] In this application, the rotation of the power pump is controlled by the rotational speed corresponding to the washing stage of the clothes. For example, the motor drives the impeller to rotate clockwise. The washing water in the outer drum enters the filter chamber through the connecting pipe and the inlet, and then enters the filter cartridge through the opening, where impurities are filtered out. Subsequently, the washing water flows through the filter holes of the filter cartridge to the gap between the filter cartridge and the pump housing, and then returns to the outer drum through the circulation port and circulation pipe to wash the clothes, thereby achieving washing water circulation.

[0180] Therefore, this embodiment determines the speed of the power pump according to different stages of garment washing, allowing the same power pump to operate at a variable speed during the washing water circulation process, not limited to a constant speed, thus meeting the operational needs of different stages. That is, the content of impurities in the clothes and the required water flow intensity vary at different stages of garment washing. By adjusting the speed of the power pump, impurities are filtered efficiently while reducing wear and tear on the clothes during the washing process. Therefore, this embodiment improves filtration efficiency, thereby enhancing washing quality and improving the cleaning effect on clothes. At the same time, it reduces power consumption and improves the performance of the washing machine.

[0181] In this embodiment, during the clothes washing stage, the operation of the power pump is controlled by a rotation speed corresponding to the washing stage, thereby driving the washing water to circulate between the inner drum and the filter. The clothes washing stage can be a washing stage or a rinsing stage. The rotation speed during the washing stage can be 3000 r / min or 1000 r / min, and the rotation speed during the rinsing stage can be 1000 r / min.

[0182] During the dehydration stage, the operation of the power pump is controlled at a speed corresponding to the dehydration stage to achieve drainage. The speed during the dehydration stage can be 3000 r / min. Optionally, the speed corresponding to the dehydration stage can be set to a higher speed to achieve rapid drainage and improve drainage efficiency.

[0183] Therefore, in this embodiment, the washing water circulation is achieved by controlling the power pump during the washing stage, and the drainage is achieved by controlling the power pump during the spin-drying stage. This allows for both washing water circulation and drainage using a single power pump, eliminating the need for multiple pumps for different scenarios, thus improving power pump utilization and simplifying the washing machine structure. Simultaneously, by incorporating a filter, impurities are trapped inside the filter after the washing water enters the pump casing, and the filtered washing water flows back to the outer drum, achieving washing water circulation and improving circulation efficiency.

[0184] In one possible embodiment, the clothes carry more impurities at the beginning of the washing process, but after a period of washing, the impurity content in the clothes and wash water may decrease. Specifically, Figure 6This is a flowchart illustrating the speed control method for the washing stage provided in this application embodiment. The method includes steps S701 to S702.

[0185] S701. During the washing stage, the power pump is controlled to drive at a first speed.

[0186] S702. After running for a first preset time, control the power pump to drive at a second speed, the second speed being less than the first speed.

[0187] In this embodiment, by determining the washing duration during the washing phase, the power pump is controlled to operate at a first rotational speed after entering the washing phase to achieve washing water circulation. After running for a first preset duration, the power pump is controlled to switch to a second rotational speed, which is lower than the first rotational speed, thereby reducing energy consumption. The first preset duration can indicate the initial stage of the washing phase, and can be 10 minutes.

[0188] Therefore, this embodiment controls the power pump to operate at a first speed during the washing stage, and then switches the first speed to a second speed after a period of operation to reduce the speed. Since the clothes carry a large amount of impurities at the beginning of the wash cycle, setting the first speed higher than the second speed allows for the rapid filtration of a large amount of impurities, improving filtration efficiency and ensuring washing results. Subsequently, reducing the speed after operating at the first speed for a period ensures filtration effectiveness, meeting the needs of different washing stages while simultaneously saving energy and extending the washing machine's lifespan.

[0189] In one possible embodiment, after controlling the power pump to operate at a second speed, the impurity content in the clothes and washing water may be reduced. To further save energy and reduce consumption, the method includes:

[0190] After controlling the power pump to run at the second speed for a second preset time, if the washing time has not reached the preset washing end threshold indicated by the washing stage, the operation of the power pump is stopped, and after a preset delay time, the power pump is controlled to run at the second speed again until the washing time reaches the preset washing end threshold.

[0191] In this embodiment, the second preset duration is a time period during the washing stage when the machine runs at the second rotation speed. The delay time can be a time period during which the power pump stops running. This washing time is the current moment since the start of the washing stage. After running for the second preset duration, it is determined whether the washing time has reached a preset end threshold for the washing stage, for example, whether the washing time is 1 minute before the end of the washing stage. On one hand, if it is determined that the washing time has reached the preset end threshold, the power pump stops running, for example, 1 minute before the end of the washing stage. On the other hand, if it is determined that the washing time has not reached the preset end threshold, the machine waits for the delay time, and then restarts the power pump at the second rotation speed until the washing time reaches the preset end threshold.

[0192] For example, Figure 7 This is a schematic diagram of the control during the washing stage provided in an exemplary embodiment of this application. After entering the washing stage, the motor of the control pump rotates clockwise to circulate the washing water, and the speed of the control pump is set to 3000 r / min to filter impurities such as lint from the washing water. After running for 10 minutes, the motor of the control pump stops working; otherwise, it continues, rotating clockwise at 3000 r / min to circulate the washing water.

[0193] like Figure 7 As shown, after a 5-minute delay, the motor of the power pump is controlled to rotate clockwise to circulate the washing water, and the speed of the power pump is set to 1000 r / min to filter out impurities such as lint from the washing water. After running for 5 minutes, it is determined whether the washing time has reached 1 minute before the end of the washing stage. If so, the motor is stopped; otherwise, the delay time is waited for another 5 minutes before the motor is controlled to circulate the washing water again.

[0194] Therefore, this embodiment ensures the cleanliness of the wash water by triggering the restart of the power pump at a second speed when the washing time has not reached the preset end threshold of the washing stage, until the washing stage ends. This embodiment eliminates the need for continuous operation of the power pump, achieving continuous purification of the wash water during the washing process, while reducing unnecessary consumption, saving energy, reducing the operating burden on the power pump, and extending the service life of the washing machine.

[0195] In one possible embodiment, the number of cycles is determined based on the weight of the clothes in the inner drum, thereby determining the number of cycles and spin speed for the clothes during the washing stage, and the number of cycles and spin speed for the rinsing stage. Specifically, Figure 8 This is a flowchart illustrating a speed control method provided in an embodiment of this application. The speed control method is used in a washing machine, which includes a drive motor for driving the rotation of the inner drum. The method includes steps S801 to S803.

[0196] S801. During the clothes washing stage, obtain the power loss of the drive motor during the driving process;

[0197] S802. Calculate the weight of the clothes in the inner drum based on the power loss.

[0198] S803. Determine the relevant rotation speed based on the weight of the clothing, and control the operation of the power pump according to the rotation speed.

[0199] In this embodiment, the weight of the clothes in the inner drum is calculated by measuring the energy loss of the drive motor during its operation. Specifically, the drive motor is controlled to rotate in different directions, and the weight of the clothes is calculated by measuring the energy loss of the drive motor during rotation and stopping. More specifically, when weighing the clothes, the drive motor is controlled to rotate in a first direction, and after a period of time, the drive motor is stopped to obtain the first energy loss. Then, after the drive motor stops rotating, it is controlled to rotate in a second direction, and after a period of time, the drive motor is stopped to obtain the second energy loss. Furthermore, the above steps are repeated to calculate the weight of the clothes in the inner drum by measuring multiple energy losses of the drive motor during its operation.

[0200] Furthermore, the number of cycles is determined based on the weight of the clothes, thereby determining the number of cycles and rotation speed for the clothes during the washing stage, as well as the number of cycles and rotation speed during the rinsing stage. This allows the operation of the power pump to be controlled according to the rotation speed, ensuring the washing effect while maintaining a reasonable energy consumption range.

[0201] Therefore, this embodiment determines the weight of the clothes in the inner drum by obtaining the power loss of the drive motor. This allows for the determination of the rotation speed for different washing stages based on the varying weights of the clothes, ensuring that the water flow rate matches the weight of the clothes. In other words, different weights of clothes correspond to different water flows, preventing excessive wear and tear on the clothes. Simultaneously, controlling the speed of the power pump based on the weight of the clothes ensures washing effectiveness while maintaining a reasonable energy consumption range, avoiding unnecessary energy waste.

[0202] In one possible embodiment, determining the rotation speed related to the washing stage of the clothes based on the weight of the clothes specifically includes:

[0203] During the washing stage, if the weight of the clothes does not reach the preset weight threshold, the power pump is controlled to run at a third speed, or if the weight of the clothes reaches the preset weight threshold, the power pump is controlled to run at a fourth speed, the fourth speed being greater than the third speed.

[0204] In this embodiment, during the washing stage, if the weight of the clothes has not reached a preset weight threshold (i.e., the clothes are relatively light), the power pump is controlled to operate at a third speed. If the weight of the clothes reaches the preset weight threshold (i.e., the clothes are relatively heavy), the power pump is controlled to operate at a fourth speed. When the clothes are heavier, the number of cycles is greater, and this fourth speed is higher than the third speed, improving the circulation efficiency of the washing water and simultaneously improving the filtration efficiency of impurities.

[0205] Therefore, in this embodiment, during the washing stage, the power pump is controlled to operate at a third speed when the weight of the clothes is low, and at a fourth speed when the weight of the clothes is high. The fourth speed is higher than the third speed, allowing heavier clothes to be washed at a higher speed, thus improving the efficiency of water circulation and consequently increasing the filtration efficiency of impurities.

[0206] In one possible embodiment, determining the rotation speed related to the washing stage of the clothes based on the weight of the clothes further includes:

[0207] During the rinsing stage, if the weight of the clothes has not reached the preset weight threshold, the power pump is controlled to run at a fifth speed, or if the weight of the clothes has reached the preset weight threshold, the power pump is controlled to run at a sixth speed, where the sixth speed is greater than the fifth speed.

[0208] In this embodiment, during the rinsing stage, if the weight of the clothes has not reached the preset weight threshold (i.e., the clothes are relatively light), the power pump is controlled to operate at the fifth speed. If the weight of the clothes reaches the preset weight threshold (i.e., the clothes are relatively heavy), the power pump is controlled to operate at the sixth speed. When the clothes are heavier, the number of cycles is greater, and the sixth speed is higher than the fifth speed, thus improving the circulation efficiency of the washing water and the filtration efficiency of impurities.

[0209] For example, Figure 9 This is a schematic diagram of a speed control method provided in an exemplary embodiment of this application, the speed control method including steps S901 to S903.

[0210] S901. Determine whether the weight of the clothing reaches the preset weight threshold.

[0211] S902. When the weight of the clothes does not reach the preset weight threshold, the power pump is controlled to run at a third speed during the washing stage and at a fifth speed during the rinsing stage.

[0212] S903. When the weight of the clothes reaches the preset weight threshold, the power pump is controlled to run at a fourth speed during the washing stage and at a sixth speed during the rinsing stage. The fourth speed is greater than the third speed and the sixth speed is greater than the fifth speed.

[0213] For example, with a preset weight threshold of 5kg, when the detected weight of the clothes is between 0-5kg (i.e., less than 5kg), the number of filtration cycles is set to 20, with 12 cycles during the washing stage at speed N1; and 8 cycles during the rinsing stage at speed N2. When the detected weight of the clothes is between 5-10kg (i.e., greater than 5kg), the number of filtration cycles is set to 40, with 24 cycles during the washing stage at speed N3; and 16 cycles during the rinsing stage at speed N4. Wherein, speed N1 is less than speed N3, and speed N2 is less than speed N4.

[0214] Therefore, in this embodiment, during the rinsing stage, the power pump is controlled to operate at a fifth speed when the weight of the clothes is low, and at a sixth speed when the weight of the clothes is high. The sixth speed is higher than the fifth speed, allowing heavier clothes to be rinsed at a higher speed, thus improving the efficiency of the washing water circulation and consequently increasing the filtration efficiency of impurities.
