Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment, and specifically provides a clothing processing device. Background Technology

[0002] With increasing health awareness and a stronger pursuit of quality of life, separate laundry washing has become a popular trend in recent years, representing a more scientific and hygienic method. This trend has led to the emergence of specialized laundry equipment designed for underwear and socks. However, these devices generally rely on a stable power supply and require connection to water pipes. Therefore, to meet users' needs for separate washing of different types of clothing while solving installation, placement, and space issues, multi-drum laundry equipment with washing drums of varying capacities has gradually emerged. This type of equipment can easily achieve separate washing of ordinary clothing, socks, and underwear, bringing great convenience to users. These devices typically share a single drainage system, which is usually equipped with a drain pump featuring a lint filter to prevent lint from getting tangled on the pump impeller and affecting drainage.

[0003] However, in actual use, people have found that these clothing processing devices with different volumes produce more lint that accumulates more easily at the lint filter of the drain pump compared to large-volume clothing processing devices that process ordinary clothes alone, or small-volume clothing processing devices that process underwear and socks alone. This can easily lead to drainage problems.

[0004] Accordingly, there is a need in the art for a new garment processing device to solve the problem of poor drainage caused by the accumulation of lint during the drainage process in existing multi-drum garment processing devices that can be used for zoned washing. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, the problem that existing multi-tub washing equipment capable of partitioning and washing clothes tends to accumulate lint during drainage, resulting in poor drainage.

[0006] In a first aspect, the present invention provides a garment processing device, comprising: a first drum having a first drain pipe thereon; a second drum having a second drain pipe thereon, the volume of the second drum being smaller than the volume of the first drum; a drain pump through which both the first drain pipe and the second drain pipe drain water; and a lint filter disposed on the first drain pipe; wherein the garment processing device is configured such that water discharged from the second drain pipe does not pass through the lint filter.

[0007] In the optional technical solution of the above-mentioned clothing processing equipment, the outlet end of the first drain pipe is connected to the inlet of the drain pump, and the outlet end of the second drain pipe is connected to the first drain pipe and is located downstream of the lint filter.

[0008] In the optional technical solution of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a first drain valve, which is disposed on the first drain pipe between the lint filter and the water outlet end of the second drain pipe.

[0009] In the optional technical solution of the above-mentioned clothing processing equipment, the second cylinder is located above the first cylinder, the second drain pipe is configured to drain downwards, the clothing processing equipment also includes a main drain pipe, the main drain pipe is connected to the outlet of the drain pump, and the main drain pipe is at least partially configured to drain upwards.

[0010] In the optional technical solution of the above-mentioned clothing processing equipment, the clothing processing equipment further includes a third cylinder with a volume smaller than that of the first cylinder. The third cylinder is located above the first cylinder. The drain outlet of the third cylinder is connected to a third pipe. The second drain pipe includes a second pipe and a manifold. The second pipe is connected to the drain outlet of the second cylinder. The second pipe and the third pipe are connected to the manifold through a T-junction structure. The manifold is used to transport water to the drain pump.

[0011] In the optional technical solutions of the above-mentioned clothing processing equipment, the three-way structure is configured as a four-position three-way valve.

[0012] In the optional technical solution of the above-mentioned clothing processing equipment, the three-way valve includes a housing, the housing having a valve cavity, the housing having a first inlet, an outlet, and a second inlet arranged sequentially along a first direction of the valve cavity, the first inlet being connected to a second pipe, the second inlet being connected to a third pipe, and the outlet being connected to a manifold. The housing has a first electromagnet and a second electromagnet respectively on opposite sides in the first direction, the valve cavity having a valve core, the valve core having a magnet protruding from both sides of the valve core in the first direction, and the magnetic poles of the magnet being opposite to the first electromagnet and the second electromagnet respectively.

[0013] In the optional technical solution of the above-mentioned clothing processing equipment, a first elastic element is provided between one side of the valve core in the first direction and the inner wall of the housing, and a second elastic element is provided between the other side of the valve core in the first direction and the inner wall of the housing. The first elastic element and the second elastic element are used to block the water outlet of the valve core under the action of elastic force.

[0014] In the optional technical solutions of the above-mentioned clothing processing equipment, the three-way structure is configured as a three-way, the second pipe is provided with a second drain valve, and the third pipe is provided with a third drain valve.

[0015] In the optional technical solutions of the above-mentioned garment processing equipment, the rear of the second cylinder and the third cylinder have a receiving space, the second pipe and the third pipe both extend from the receiving space to the bottom of the first cylinder, and extend downward along the bottom of the cylinder; and / or the lint filter and the drain pump are both located at the bottom of the casing of the garment processing equipment.

[0016] Those skilled in the art will understand that the garment processing device of the present invention includes a first drum, a second drum, a drain pump, and a lint filter. The first drum has a first drain pipe, and the second drum has a second drain pipe. The volume of the second drum is smaller than the volume of the first drum. Both the first drain pipe and the second drain pipe drain water through the drain pump. The lint filter is disposed on the first drain pipe. The garment processing device is configured such that the water discharged from the second drain pipe does not pass through the lint filter.

[0017] This invention separates the drain pump and the lint filter. A smaller, second-drum unit is specifically designed for washing small items of clothing. The water discharged from this unit flows directly through a second drain pipe and is then pumped out. Since the lint discharged from the second drum consists only of fine lint, larger lint tends to get tangled on the impeller shaft during actual drainage. The fine lint is directly carried away by the water flow and pumped out without causing blockage. The larger, first-drum unit, used for washing regular clothing, has its water filtered through a lint filter on a first drain pipe before entering the pump. This ensures that only fine lint passes through the pump, preventing blockage. Furthermore, because fine lint bypasses the lint filter, only large lint is intercepted. This avoids the situation where both fine and large lint pass through the filter, which is prone to clogging. Therefore, this invention ensures the lint filter maintains good filtration performance for an extended period, guaranteeing smooth drainage. In summary, the garment processing device of the present invention can ensure the smooth drainage of the entire drainage system. Attached Figure Description

Detailed Implementation

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0029] It should be noted that, in the description of this invention, the terms "upper" and "lower" refer to the upper and lower parts of the garment processing equipment in its operational state, based on the height direction. "Horizontal direction" refers to the horizontal direction of the garment processing equipment after installation, consistent with its operational horizontal direction. "Front" refers to the side of the garment processing equipment closest to the door, and "rear" refers to the side of the garment processing equipment closest to the back panel opposite the door. Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Figure 1 This is a prior art drainage pump. The prior art drainage pump includes a housing 110, an inlet 111 in the middle of the side wall of the housing 110, an impeller 120 inside the housing 110, the impeller 120 being vertically arranged on one side of the housing 110, a drain outlet 112 at the top of the side wall of the housing 110 corresponding to the position of the impeller 120, a motor 140 being arranged on the outside of the housing 110 and being drivenly connected to the impeller 120, and a filter element 130 being arranged inside the housing 110. Taking the illustration as an example, the outer casing 110 has an opening on the side opposite to the impeller. The filter element 130 includes an end cap 131 on the opening, a central post 132 and an edge member 133 on the end cap 131. The edge member 133 is located around the central post 132 and is spaced apart. The filter element 130 also includes a hollow conical member 134. The conical member 134 is located on the side opposite to the end cap 131 of the edge member 133, and the central post 132 is located in the conical member 134. Taking the drainage pump of a multi-drum laundry equipment used for partitioned washing as an example, the applicant's research found that, because the large drum washes regular outerwear and / or bedding, which contains coarse lint and / or foreign objects, while the small drum washes underwear and / or socks, which are smaller and do not have pockets, they do not contain large lint like toilet paper; instead, they contain fine lint without foreign objects. When the large and small drums of the multi-drum laundry equipment drain alternately, there are still enough gaps between the coarse lint accumulated in the filter element of the drain pump for water to pass through, and drainage blockage will not cause the washing machine to alarm in the short term. However, when the large and small drums of the multi-drum laundry equipment drain simultaneously, and the fine lint increases dramatically, it will block the gaps between the coarse lint, causing the lint filter to become clogged quickly, leading to poor drainage, washing interruption, and washing machine alarm. A similar blockage principle can be referred to as the sealing solution for a breached dam. Simply using large stones is difficult to completely seal the breach, and simply using sand will be quickly washed away by the water flow and will not be able to seal it. Only by first adding stones and then sand can the breach be sealed.

[0031] Based on the above research and analysis, this application provides a garment processing device. First, the garment processing device of the present invention will be briefly introduced.

[0032] like Figure 2 As shown, the garment processing device of the present invention includes a first drum 210, a second drum 220, a drain pump 300, and a lint filter 400. The first drum 210 has a first drain pipe 510, and the second drum 220 has a second drain pipe 520. The volume of the second drum 220 is smaller than the volume of the first drum 210. Both the first drain pipe 510 and the second drain pipe 520 drain water through the drain pump 300. The lint filter 400 is disposed on the first drain pipe 510. The garment processing device is configured such that the water discharged from the second drain pipe 520 does not pass through the lint filter 400.

[0033] This invention separates the drain pump 300 and the lint filter 400. The smaller second drum 220 is specifically used for washing small items of clothing. The water discharged from it is directly discharged through the second drain pipe 520 and then through the drain pump 300. Since the lint discharged from the second drum 220 is only fine lint, in the actual drainage process, only large lint tends to get tangled on its impeller shaft. The fine lint can be directly discharged by the water flow through the drain pump 300, and the fine lint will not cause the drain pump 300 to become clogged. The larger first drum 210, used for washing ordinary clothes, has its discharged water filtered first through the lint filter 400 on the first drain pipe 510 before entering the drain pump 300. In this way, only fine lint passes through the drain pump 300, and no large lint passes through, so the drain pump 300 will not become clogged. Furthermore, since fine lint does not pass through the lint filter 400, only large lint is intercepted by it. This prevents both large and fine lint from passing through the lint filter 400, which is more likely to cause clogging if both large and small lint pass through. Therefore, the technical solution of this invention allows the lint filter 400 to maintain a good filtration effect for a long time, ensuring smooth drainage. At the same time, the drainage system structure of the above-described configuration is simple, reducing space occupation. In summary, the garment processing device of this invention can ensure smooth drainage of the entire drainage system.

[0034] The specific embodiments of the garment processing device of the present invention are described below.

[0035] The garment processing device of the present invention can be a drum washing machine or a washer-dryer combo, etc., including a first drum 210, a second drum 220, a third drum 230, a drain pump 300, and a lint filter 400 disposed within a casing 800. Each of the first drum 210, the second drum 220, and the third drum 230 may have a rotatable inner drum. The volume of the second drum 220 is equal to and smaller than that of the third drum 230 than that of the first drum 210. The second drum 220 and the third drum 230 are arranged side-by-side and are both located above the first drum 210. The drain outlet of the first drum 210 is connected to a first drain pipe 510. The outlet of the first drain pipe 510 is connected to the inlet of the drain pump 300. The outlet of the drain pump 300 is connected to a main drain pipe 540. The lint filter 400 is disposed on the first drain pipe 510. When the lint filter 400 has an inlet and a drain outlet, it can be directly connected to the first drain pipe 510 through the inlet and the drain outlet. The drain outlet of the second cylinder 220 is connected to a second drain pipe 520. The second drain pipe 520 can be divided into two sections: one section is a second pipe 521 connected to the drain outlet of the second cylinder 220, and the other section is a manifold 522. The drain outlet of the third cylinder 230 is connected to a third pipe 530. The second pipe 521 and the third pipe 530 are connected to the manifold 522 through a tee structure. The outlet of the manifold 522 is connected to the first drain pipe 510 and is located downstream of the lint filter 400. The garment processing equipment also includes a first drain valve 600, which is located on the first drain pipe 510 between the lint filter 400 and the outlet of the manifold 522.

[0036] It should be noted that the present invention does not limit the specific structure of the wire lint filter 400 and the drain pump 300. The existing drain pump 300 described above, after removing the motor and impeller and other related components, constitutes the wire lint filter 400 of the present invention. In this case, the arrangement of the inlet and outlet on the housing of the wire lint filter 400 is not limited; for example, both the inlet and outlet can be located on the side wall of the housing. However, this is not a limitation; the wire lint filter 400 can also be replaced with a filter screen or other type of filter. In this case, the wire lint filter 400 is directly installed in the first drain pipe 510. The drain pump 300 can be any existing or future drain pump 300 structure, which will not be described in detail in the present invention.

[0037] The smaller drums 220 and 230 are specifically designed for washing small items of clothing, such as underwear and socks. Since these items are small and don't have pockets, they are free of foreign objects and large lint like toilet paper; only fine lint remains. The first drum 210 is specifically for washing regular clothing, such as outerwear and bedding, which may contain larger lint and other foreign objects. This invention separates the drain pump 300 and the lint filter 400. When the second cylinder 220 and / or the third cylinder 230 drains water, the discharged water is directly discharged through the drain pump 300 after passing through the second pipe 521 and / or the third pipe 530 and the manifold 522. Since the discharged water contains only fine lint, in the actual drainage process, only large lint is easily wrapped around its impeller shaft. The fine lint can be directly discharged by the water flow through the drain pump 300, and the fine lint will not cause the drain pump 300 to be blocked. The water discharged from the first cylinder 210 will first pass through the lint filter 400 on the first drain pipe 510 before entering the drain pump 300. In this way, only fine lint passes through the drain pump 300, and no large lint passes through, so the drain pump 300 will not be blocked. Furthermore, since fine lint does not pass through the lint filter 400, only large lint is intercepted by it. This prevents both large and fine lint from passing through the lint filter 400, which is more likely to cause clogging if both large and small lint pass through. Therefore, the technical solution of this invention allows the lint filter 400 to maintain a good filtration effect for a long time, ensuring smooth drainage. In summary, the garment processing equipment of this invention can ensure the smooth drainage of the entire drainage system.

[0038] Furthermore, since the first drain valve 600 is located on the first drain pipe 510 between the wire lint filter 400 and the outlet end of the second drain pipe 520, when the first cylinder 210 is not draining, the first drain valve 600 will be in the closed state. Due to the obstruction of the first drain valve 600, the water discharged from the second cylinder 220 and / or the third cylinder 230 will not pass through the first drain valve 600 and reach the wire lint filter 400, which can further reduce the probability of the wire lint filter 400 becoming clogged. It can be understood that when the first cylinder 210 is draining, although the first drain valve 600 is open, the water flow direction is towards the drain pump 300, so the water discharged from the second cylinder 220 and / or the third cylinder 230 will not flow towards the wire lint filter 400.

[0039] Possibly, both the lint filter 400 and the drain pump 300 are located on the bottom wall of the housing 800. The first drain pipe 510 can be connected to the bottom of the side wall of the first cylinder 210, etc. The first drain pipe 510 extends downward from the drain outlet of the first cylinder 210 to the bottom wall of the housing 800, and is arranged along the bottom wall to connect with the lint filter 400 and the drain pump 300. The drain main pipe 540 connected to the outlet of the drain pump 300 is at least partially configured to drain upward. Specifically, the drain main pipe 540 extends upward to a set height and then bends downward to form an inverted U-shaped structure. The second pipe 521 can be connected to the bottom of the side wall or the bottom of the second cylinder 220, etc., and the third pipe 530 can be connected to the bottom of the side wall or the bottom of the third cylinder 230, etc. The second pipe 521, the third pipe 530, and the manifold 522 are all configured for downward drainage. Specifically, the rear of the second cylinder 220 and the third cylinder 230 has a receiving space, which refers to the space located above the first cylinder 210 and behind the second cylinder 220 and the third cylinder 230. The second pipe 521 and the third pipe 530 extend along the top wall of the first cylinder 210 to the bottom of the first cylinder 210 within the receiving space, and then extend downward along the bottom of the first cylinder 210. The manifold 522 extends downward along the bottom of the first cylinder 210 and then connects to the first drain pipe 510. The manifold 522 can be connected to the first drain pipe 510 via a tee, but this is not a limitation. For example, an opening can be provided on the first drain pipe 510, and the outlet end of the manifold 522 can be sealed to the opening. These adjustments do not deviate from the principle of the present invention and are all within the protection scope of the present invention.

[0040] Because of the need for a minimalist style and more practical space utilization, most homeowners now choose wall-mounted drains during renovations. Wall-mounted drains place the water inlet on the wall, eliminating the need for floor drains and pipes, freeing up space and creating a cleaner look. However, there's no standard height for wall-mounted drain openings; it varies greatly from person to person. Within a height range of 850mm, the higher the opening, the cleaner the look and the more space it frees up. To facilitate integration into standard cabinets, the multi-drum laundry processing device of this invention is typically the size of a standard washing machine (European standard: 850mm high, 600mm wide), with an overall height of only 850mm. The bottom of the upper second drum 220 and third drum 230 does not exceed 850mm. Furthermore, to ensure sufficient washing capacity for the second drum 220 and third drum 230 (drum tumbling washing; the larger the drum diameter, the greater the tumbling force and the stronger the washing capacity), the diameters of the second drum 220 and third drum 230 are both close to 300mm. In other words, when the second drum 220 and third drum 230 use bottom drainage, the wall drain inlet height, including the height of other components, must typically be less than 500mm. If this height is exceeded, the second drum 220 and third drum 230 will be unable to complete drainage when using bottom drainage, which will greatly limit the application scenarios of the multi-drum washing machine. To address this issue, the present invention discharges the wastewater from the second cylinder 220 and the third cylinder 230 through the drainage pump 300 on the first drainage pipe 510. Therefore, even if the second pipe 521, the third pipe 530 and the manifold 522 are configured to drain downwards, they can accommodate wall drains and floor drains of all heights. There are no restrictions on the installation conditions of the clothing processing equipment. The main drainage pipe 540 can adopt an upward drainage design at any height.

[0041] In addition, since the second pipe 521 and the third pipe 530 of the present invention both extend from the accommodating space to the bottom of the first cylinder 210, the rear space of the second cylinder 220 and the third cylinder 230 with smaller upper volume can be fully utilized. The second pipe 521 and the third pipe 530 are extended downward along the bottom of the cylinder and connected to the manifold 522 through a three-way structure, which can reduce the space occupied by the drainage system and provide space for the installation of other components.

[0042] like Figures 3 to 6As shown, the three-way structure can be configured as a four-position three-way valve 700. The four-position three-way valve 700 includes a housing 710, which contains a valve cavity 714. The housing 710 has a first inlet 711, an outlet 712, and a second inlet 713 arranged sequentially along a first direction of the valve cavity 714. The first inlet 711 and the second inlet 713 can both be located on opposite sides of the outlet 712. The first inlet 711 is connected to a second pipe 521, the second inlet 713 is connected to a third pipe 530, and the outlet 712 is connected to a manifold 522. The housing 710 has a first electromagnet 720 and a second electromagnet 730 respectively on opposite sides of the first direction. Specifically, the housing 710 has a first receiving cavity and a second receiving cavity on opposite sides of the valve cavity 714 in the first direction. The first electromagnet 720 can be fixed in the first receiving cavity by bolts or clips, and the second electromagnet 730 can be fixed in the second receiving cavity by bolts or clips. A valve core 740 is provided inside the valve cavity 714. The valve core 740 can slide in a sealing contact with the valve cavity 714. A magnet 750 is provided on the valve core 740, protruding from both sides of the valve core 740 in the first direction. The magnetic poles of the magnet 750 are respectively opposite to the first electromagnet 720 and the second electromagnet 730. A first elastic element 760 is provided between one side of the valve core 740 in the first direction and the inner wall of the housing 710, and a second elastic element 770 is provided between the other side of the valve core 740 in the first direction and the inner wall of the housing 710. The first elastic element 760 and the second elastic element 770 are used to block the outlet 712 of the valve core 740 under the action of elastic force. The first elastic element 760 and the second elastic element 770 can be a compression spring or a spring sheet, etc. In addition, to facilitate the movement of the valve core 740, a guide pipe can be provided on the housing 710. One end of the guide pipe is connected to the valve cavity 714 on one side of the valve core 740, and the other end is connected to the side wall of the second inlet 713.

[0043] The present invention does not limit the specific manner in which the magnet 750 is mounted on the valve core 740. For example, the valve core 740 may have a through hole extending along the first direction, with the center of the magnet 750 disposed in this through hole. Alternatively, the magnet 750 may be connected to the side of the valve core 740 by bolts, snap-fits, or other means. As long as the magnet 750 protrudes from both sides of the valve core 740 in the first direction, any adjustments to the specific implementation do not deviate from the principle of the present invention and are within the protection scope of the present invention. The surface of the magnet 750 may also be covered with insulating material to prevent damage to the magnet when hot water is discharged.

[0044] The working principle of the garment processing device of the present invention will be described below.

[0045] Reference Figure 2 and Figure 3When only the first cylinder 210 needs to drain, the first electromagnet 720 and the second electromagnet 730 are de-energized, and the first elastic element 760 and the second elastic element 770 achieve thrust balance, so that the valve core 740 closes the outlet 712. At the same time, the drain pump 300 and the first drain valve 600 are opened. The water in the first cylinder 210 passes through the lint filter 400 on the first drain pipe 510 and is discharged through the drain pump 300 and the main drain pipe 540.

[0046] Reference Figure 2 and Figure 4 When only the second cylinder 220 needs drainage, the first drain valve 600 is closed, the drain pump 300 is turned on, and the second electromagnet 730 is controlled to apply a current in the first current direction. The second electromagnet 730 attracts the magnet 750, causing the valve core 740 to overcome the thrust of the second elastic element 770 and move a set distance closer to the second electromagnet 730. The valve core 740 then closes the second inlet 713, and the first inlet 711 and outlet 712 are connected. In this case, the water in the second cylinder 220 passes through the second pipe 521, the first inlet 711 and outlet 712 of the four-position three-way valve 700, and is then discharged through the drain pump 300 and the main drain pipe 540.

[0047] Reference Figure 2 and Figure 5 When only the third cylinder 230 needs drainage, the first drain valve 600 is closed, the drain pump 300 is opened, and the first electromagnet 720 is controlled to apply a current in the first current direction. The first electromagnet 720 attracts the magnet 750, causing the valve core 740 to overcome the thrust of the first elastic element 760 and move a set distance closer to the first electromagnet 720. The valve core 740 then closes the first inlet 711, and the second inlet 713 and outlet 712 are connected. In this case, the water in the third cylinder 230 passes through the third pipe 530, the second inlet 713 and outlet 712 of the four-position three-way valve 700, and is then discharged through the drain pump 300 and the main drain pipe 540.

[0048] Reference Figure 2 and Figure 6When the first cylinder 210, the second cylinder 220, and the third cylinder 230 drain water simultaneously, the first drain valve 600 and the drain pump 300 are opened, and the first electromagnet 720 is controlled to apply current in the second current direction, while the second electromagnet 730 applies current in the first current direction. The first electromagnet 720 applies a repulsive force to the magnet 750, and the second electromagnet 730 applies an attractive force to the magnet 750, causing the first elastic element 760 to naturally extend and the second elastic element 770 to be compressed. The valve core 740 moves to the end towards the second electromagnet 730, and both the first inlet 711 and the second inlet 713 are opened and connected to the outlet 712. The water from the first cylinder 210 passes through the lint filter 400 on the first drain pipe 510 and is discharged through the drain pump 300 and the main drain pipe 540. The water from the second cylinder 220 and the third cylinder 230 passes through the four-position three-way valve 700 and is discharged through the drain pump 300 and the main drain pipe 540. Understandably, when the first drain cylinder 210 is not draining, the first drain valve 600 can be closed.

[0049] Other drainage situations will not be described in detail. For example, if only the first cylinder 210 and the second cylinder 220 drain water, or only the first cylinder 210 and the third cylinder 230 drain water, the corresponding drainage pipe can be connected to the drainage pump 300 by controlling the first drainage valve 600 and the four-position three-way valve 700.

[0050] In this invention, a first elastic element 760 is provided between one side of the valve core 740 in the first direction and the inner wall of the housing 710, and a second elastic element 770 is provided between the other side of the valve core 740 in the first direction and the inner wall of the housing 710. The first elastic element 760 and the second elastic element 770 are used to seal the outlet 712 of the valve core 740 under the action of elastic force. This allows the valve core 740 to stably seal the middle outlet 712 under the action of the first elastic element 760 and the second elastic element 770. In addition, since this invention does not make the valve core 740 into a magnet 750, but rather provides a magnet 750 on the valve core 740, and the magnet 750 protrudes from both sides of the valve core 740 in the first direction, with the magnetic poles facing the first electromagnet 720 and the second electromagnet 730 respectively. This design allows the magnet 750 to fully engage with the first electromagnet 720 when the valve core 740 blocks the first inlet 711; and when the valve core 740 fully opens both the first and second inlets 711 and 713, the magnet 750 can fully engage with the second electromagnet 730. In this case, the magnetic force is very strong, which can quickly reduce the current, thus reducing energy consumption and increasing control reliability. If the valve core 740 were made into a magnet 750, the elastic force of the elastic element would prevent the valve core 740 from fully engaging with either the first electromagnet 720 or the second electromagnet 730, resulting in higher energy consumption. This invention avoids this problem.

[0051] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0052] For example, as an alternative implementation, the third cylinder 230 and the third tube 530 can be omitted.

[0053] For example, as an alternative implementation, the volumes of the second cylinder 220 and the third cylinder 230 may not be equal.

[0054] For example, as an alternative implementation, the second cylinder 220 and the third cylinder 230 can be staggered.

[0055] For example, as an alternative implementation, the second cylinder 220 and / or the third cylinder 230 may be disposed on the side of the first cylinder 210.

[0056] For example, as an alternative implementation, the main drain pipe 540 can be omitted.

[0057] For example, as an alternative implementation, the T-junction structure can be omitted. In this case, the second drain pipe 520 is not segmented, and the third pipe 530 can be directly connected to the first drain pipe 510.

[0058] For example, as an alternative implementation, the outlet of the second drain pipe 520 is not connected to the first drain pipe 510. In this case, two inlets can be provided on the drain pump 300, one of which is connected to the outlet of the first drain pipe 510, and the other inlet is connected to the outlet of the second drain pipe 520. The key is to ensure that the water discharged from the second drain pipe 520 is discharged directly through the drain pump 300 without passing through the lint filter 400.

[0059] For example, as an alternative implementation, the first drain valve 600 can be omitted, and due to the inverted U-shaped design of the drain manifold 540, the water in the first tub 210 will not be discharged during washing.

[0060] For example, as an alternative implementation, the lint filter 400 can be disposed on the side wall of the housing 800, and the drain pump 300 can also be disposed on the side wall of the housing 800.

[0061] For example, as an alternative implementation, the first elastic member 760 and the second elastic member 770 can be omitted.

[0062] For example, as an alternative implementation, the three-way valve can be replaced with a three-way valve. In this case, a second drain valve can be installed on the second pipe 521 and a third drain valve can be installed on the third pipe 530.

[0063] For example, as an alternative implementation, the first inlet 711, the outlet 712, and the second inlet 713 may be located on the same side of the housing 710.

[0064] For example, as an alternative implementation, the first receiving cavity and / or the second receiving cavity can be omitted, and the first electromagnet 720 and / or the second electromagnet 730 can be disposed on the outside of the housing 710.

[0065] For example, as an alternative implementation, the inner drum of at least one of the first, second, and third drums can be omitted, and agitators or beaters for washing clothes can be installed in the corresponding drums.

[0066] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
