[0001] The present application relates to the technical field of household appliances, and in particular to a reverse stopping device of a clothes treatment apparatus and the clothes treatment apparatus. BACKGROUND

[0002] A known clothes treatment apparatus (such as a drum washing machine, a washer-dryer, etc.) has a water containing tub and a washing tub, the washing tub is rotatably arranged in the water containing tub, during the execution of a washing process, clothes in the washing tub are tumbled by the rotation of the washing tub, plus the joint action of washing water and detergent, to achieve the washing effect of clothes.

[0003] The above clothes treatment apparatus usually also carries a drying device, a care device, etc., these devices send hot air, care medium, etc. to the water containing tub through a fluid channel, to implement drying, deodorization, antibacterial, wrinkle removal and other care operations on clothes. During the execution of the washing process, a large amount of foam is generated in the water containing tub and the washing tub, with the operation of the washing tub, the foam, washing water, etc. are squeezed out and flow into the above fluid channel in the opposite direction (opposite to the original fluid flow direction in the fluid channel), causing problems such as foam overflow and electronic devices being wet. The common reverse stopping means in the prior art is to add a reverse stopping structure (such as a reverse stopping valve, a reverse stopping piece, etc.) in the fluid channel to block the reverse flow fluid (such as the above foam and washing water), however, in the case of large reverse flow volume and long duration, the reverse flow fluid is easily accumulated in front of the reverse stopping structure, which may cause leakage and even failure of the reverse stopping structure. The present application studies the above problems and proposes a solution. SUMMARY

[0004] The purpose of the present application is to provide a reverse stopping device of a clothes treatment apparatus, which at least partially solves the above-mentioned technical problems.

[0005] To solve the above technical problems, the present application adopts the following technical solutions:

[0006] The reverse stopping device of the clothes treatment apparatus comprises:

[0007] a main channel for fluid flow; and

[0008] a reverse stopping piece arranged in the main channel, the reverse stopping piece has an open state allowing the forward flow fluid in the main channel to pass through and a closed state preventing the reverse flow fluid in the main channel from passing through; and

[0009] a bypass channel communicating with the main channel, for guiding the reverse flow fluid in the main channel when the reverse stopping piece is in the closed state.

[0010] In the above reverse stopping device of the clothes treatment apparatus, the bypass channel is closed when the reverse stopping piece is in the open state.

[0011] In the reverse flow preventing device of the laundry treating apparatus, the bypass passage has a bypass opening communicating with the main passage, and the reverse flow preventing member is provided with a plug for closing the bypass opening when the reverse flow preventing member is in the open state.

[0012] In the reverse flow preventing device of the laundry treating apparatus, the reverse flow preventing member is limited to be opened in the reverse flow direction within the main passage.

[0013] In the reverse flow preventing device of the laundry treating apparatus, an inner wall of the main passage is provided with a blocking portion for stopping the reverse flow preventing member in the reverse flow direction, so as to limit the reverse flow preventing member to be opened in the reverse flow direction.

[0014] In the reverse flow preventing device of the laundry treating apparatus, the reverse flow preventing member is provided with a first magnet, and the main passage is provided with a second magnet corresponding to the reverse flow preventing member in the closed state, the first magnet and the second magnet are attracted to each other, so as to limit the reverse flow preventing member to be opened in the reverse flow direction.

[0015] In the reverse flow preventing device of the laundry treating apparatus, the reverse flow preventing member comprises a baffle plate matched with the cross section of the main passage, the baffle plate is arranged in a normally closed structure and is opened in the forward flow direction by the action of the forward flow fluid.

[0016] In the reverse flow preventing device of the laundry treating apparatus, one side of the baffle plate is rotationally connected with the main passage, and the center of gravity of the baffle plate is lower than the rotation connection position of the baffle plate, so that the baffle plate is kept in the closed state by gravity.

[0017] In the reverse flow preventing device of the laundry treating apparatus, the reverse flow preventing member further comprises an elastic component, the baffle plate is kept in the closed state by the elastic action force of the elastic component; or the baffle plate is an elastic plate, and the baffle plate partially constitutes the elastic component and is connected to the inner wall of the main passage by the elastic component.

[0018] The present application further provides a laundry treating apparatus comprising the reverse flow preventing device according to any one of the technical solutions.

[0019] In the laundry treating apparatus, the laundry treating apparatus comprises a water containing tub and a washing tub arranged in the water containing tub, the water containing tub has an air inlet, one end of the main passage communicates with the air inlet, and the other end is provided with a fan and an electrostatic atomization device capable of generating atomized particles, and the forward flow fluid is the airflow carrying the atomized particles formed in the main passage when the fan is working.

[0020] In the laundry treating apparatus, the reverse flow fluid is washing fluid or foam overflowing from the washing tub to the outside through the air inlet.

[0021] In the laundry treating apparatus, the bypass channel guides the backflow fluid to the detergent box and / or the drain valve.

[0022] Advantages of the present application:

[0023] The backflow prevention device of the laundry treating apparatus according to the present application is provided with a bypass channel on the main channel. When the backflow fluid enters the main channel, the backflow prevention member is in a closed state, preventing the backflow fluid from passing through the backflow prevention member. Part of the backflow fluid blocked by the backflow prevention member is guided outwards from the bypass channel, thereby reducing the burden on the backflow prevention member and reducing the risk of the backflow prevention member being penetrated by the backflow fluid or even failing.

[0024] Further, the backflow prevention member closes the bypass channel when it is in an open state. When the forward flow fluid flows through the main channel, the backflow prevention member closes the bypass channel, preventing the forward flow fluid from flowing out of the bypass channel and causing waste.

[0025] Further, the backflow prevention member is limited to open in the backflow direction within the main channel. The structural stability of the backflow prevention member is improved, preventing the backflow prevention member from being pushed open in the reverse direction by the backflow fluid, which can cause the backflow prevention member to fail.

[0026] Further, the backflow prevention member includes a baffle plate that is adapted to the cross section of the main channel. The baffle plate is configured as a normally closed structure and is driven to rotate and open in the forward flow direction by the action of the forward flow fluid. The action of the forward flow fluid drives the baffle plate to rotate and open, which is a passive opening method that does not require additional mechanical power. This makes the backflow prevention member simple in structure and achieves effective backflow prevention function at low cost.

[0027] The laundry treating apparatus according to the present application is provided with the backflow prevention device according to any one of the above technical solutions, and therefore has all the technical effects of the backflow prevention device.

[0028] Further, the laundry treating apparatus includes a water containing tub and a washing tub arranged in the water containing tub. The water containing tub has an air inlet, one end of the main channel is communicated with the air inlet, and the other end is provided with a fan and an electrostatic atomization device capable of generating atomized particles. The forward flow fluid is the airflow carrying the atomized particles formed in the main channel when the fan is working. The electrostatic atomization device generates atomized particles by ionizing water molecules in the air. The atomized particles enter the water containing tub and the washing tub along the main channel under the driving of the airflow, and implement odor removal, bacteria removal and other care on the laundry. The backflow prevention device according to the present application can more reliably achieve the backflow prevention function, and avoid the influence of the backflow fluid on the output of the atomized particles and the working stability of the electrostatic atomization device.

[0029] In the laundry treating apparatus, the backflow fluid is the washing fluid or foam overflowing from the washing tub through the air inlet. The backflow preventing device of the present application can effectively prevent the charging components of the electrostatic atomizing device from being damaged by the washing fluid or foam.

[0045] The reverse stopping device of the laundry treating apparatus comprises a main channel for fluid flow; a reverse stopping member arranged in the main channel, the reverse stopping member having an open state allowing the fluid in the main channel to flow and a closed state preventing the fluid in the main channel from flowing; and a bypass channel communicating with the main channel for guiding the fluid in the main channel when the reverse stopping member is in the closed state. When the reverse fluid flows into the main channel, the reverse stopping member is in the closed state to prevent the reverse fluid from passing through the reverse stopping member, and the part of the reverse fluid blocked by the reverse stopping member is guided out from the bypass channel, thereby reducing the burden of the reverse stopping member and lowering the risk of the reverse stopping member being penetrated by the reverse fluid or even failing.

[0046] The technical solutions of the embodiments of the present application are explained and described below in combination with the drawings of the embodiments of the present application. However, the following embodiments are only preferred embodiments of the present application, and not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0047] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0048] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] In the present application, unless otherwise explicitly specified and limited, "on" or "under" of a first feature to a second feature can include that the first and second features are in direct contact, or can include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "over" of a first feature to a second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. "Under", "below" and "underneath" of a first feature to a second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.

[0050] Referring to Figure 1 , 2 In one embodiment of the present application, the reverse stopping device of the laundry treating apparatus includes: a main passage 100 for fluid flow; a reverse stopping member disposed in the main passage 100, the reverse stopping member having an open state allowing the fluid in the main passage 100 to flow forward and a closed state preventing the fluid in the main passage 100 from flowing backward; and a bypass passage 300 communicating with the main passage 100 for guiding the fluid flowing backward in the main passage 100 when the reverse stopping member is in the closed state.

[0051] In the present embodiment, the reverse stopping member includes a baffle 200 adapted to the cross section of the main passage 100 to sufficiently block the fluid flowing backward, for example, the main passage 100 has a circular cross section, and the baffle 200 is also designed to be circular, but the baffle 200 and the main passage 100 are in clearance fit, and the baffle 200 is not interfered by the main passage 100 in opening and closing. The baffle 200 is designed to be normally closed, that is, it remains in the closed state without external force, and is opened in the forward direction by the force of the fluid flowing forward. This passive opening without additional mechanical power makes the reverse stopping member simple in structure and low in cost, and effectively realizes the reverse stopping function.

[0052] As a preferred solution, the upper end of the baffle 200 is rotatably connected to the main passage 100, for example, the upper end of the baffle 200 is provided with a rotating shaft 210, and the inner wall of the main passage 100 is provided with a clamping groove, and the rotating shaft 210 is rotatably limited in the clamping groove. Since the upper end of the baffle 200 is rotatably connected to the main passage 100, the center of gravity of the entire baffle 200 is lower than the rotating connection part of the baffle 200, and the baffle 200 relies on gravity to maintain a free falling state to block the fluid flowing backward (as shown in Figure 1 The force of the fluid flowing forward applied on the baffle 200 is greater than the gravity of the baffle 200, so that the fluid flowing forward can push the baffle 200 in the forward direction (as shown in Figure 2 For example, the flow rate and flow volume of the air flow are increased by means of the fan power, so as to ensure that the thrust of the air flow can push the baffle 200.

[0053] The backflow fluid generated in the laundry treatment apparatus is mainly washing fluid or foam, and is backflow, which generates a force that is usually not strong enough to push the baffle 200 in the backflow direction, but when a large amount of backflow fluid or vibration of the laundry treatment apparatus occurs, the baffle 200 is not easy to maintain in the closed state, and thus the baffle 200 is limited to be opened in the backflow direction in the main passage 100, thereby improving the structural stability of the backflow prevention member and preventing the backflow prevention member from being pushed in the reverse direction by the backflow fluid to cause backflow prevention failure. For example, a blocking portion 130 that blocks the backflow prevention member in the backflow direction is provided on the inner wall of the main passage 100, and when the baffle 200 is maintained in a free-falling state by gravity, the lower end of the baffle 200 is abutted against the blocking portion 130, so that the backflow fluid cannot push the baffle 200 in the backflow direction due to the blocking of the blocking portion 130. In a specific implementation, the blocking portion 130 can be a step that is integrally formed on the inner wall of the main passage 100, or can be a blocking block that is independently installed on the inner wall of the main passage 100.

[0054] It can be understood that the rotating connection position of the baffle 200 is not limited to the upper end of the baffle 200, as long as the center of gravity of the baffle 200 is lower than the rotating connection position of the baffle 200 when the baffle 200 is rotatably connected to the inner wall of the main passage 100, and theoretically, the baffle 200 can be maintained in the closed state under the action of gravity, and thus in other embodiments, the middle portion or the portion above the middle portion of the baffle 200 can be rotatably connected to the main passage 100.

[0055] Continuing to refer to Figure 1 , 2 , the two ends of the main passage 100 are set as the inflow port 110 and the outflow port 120, respectively, the forward flow fluid flows in the main passage 100 from the inflow port 110 to the outflow port 120, and the backflow fluid flows in the main passage 100 from the outflow port 120 to the inflow port 110, and in this embodiment, the bypass passage 300 is connected to the main passage 100 between the backflow prevention member (baffle 200) and the outflow port 120, and is as close as possible to the backflow prevention member in the structure, so that the part of the backflow fluid blocked by the backflow prevention member can be more effectively and quickly guided out from the bypass passage 300, thereby reducing the burden of the backflow prevention member and reducing the risk of penetration and even failure of the backflow prevention member by the backflow fluid.

[0056] In an embodiment of the present application, based on the backflow prevention device described in the above embodiment: the backflow prevention member closes the bypass passage 300 when the backflow prevention member is in the opened state, and when the forward flow fluid flows through the main passage 100, the backflow prevention member closes the bypass passage 300 to prevent the forward flow fluid from being wasted by flowing out from the bypass passage 300. Referring to Figure 2For example, in the foregoing embodiment, the bypass passage 300 has a bypass opening 310 communicating with the main passage 100, and the side of the flap 200 facing the bypass opening 310 is provided with the plug 220. When the flap 200 is opened by the flow of the fluid, the plug 220 blocks the bypass opening 310, preventing the fluid from flowing out of the bypass passage 300 and being wasted.

[0057] In one embodiment of the present application, based on the foregoing embodiment, another scheme for limiting the opening of the check member in the reverse flow direction is provided. The check member is provided with a first magnet, and the main passage is provided with a second magnet corresponding to the closed state of the check member. The first magnet and the second magnet attract each other to limit the opening of the check member in the reverse flow direction. For example, in the foregoing embodiment, the first magnet is arranged at the lower end of the flap, and the second magnet is arranged on the inner wall of the main passage corresponding to the closed state of the flap. In the closed state of the flap, the first magnet and the second magnet attract each other to limit the opening of the flap in the reverse flow direction and prevent the flap from swinging back and forth. The stability of the closed state of the flap is good, but the force exerted by the fluid on the flap is greater than the magnetic attraction force between the first magnet and the second magnet, ensuring that the flap can be pushed open by the fluid.

[0058] In one embodiment of the present application, based on the foregoing embodiment, the check member further includes an elastic component. The flap is kept in the closed state by the elastic force exerted by the elastic component. That is, the flap can be reset by the elastic force exerted by the elastic component after being opened. For example, in the foregoing embodiment, the elastic component is a torsion spring. The torsion spring is installed on the rotating shaft at the upper end of the flap and is kept in a pre-tightened state. The force exerted by the fluid on the flap is greater than the elastic force of the torsion spring, ensuring that the flap can be pushed open by the fluid. Without other external forces, the flap is reset to the closed state by the elastic force of the torsion spring and its own gravity and is kept in the closed state.

[0059] In other embodiments, the flap is a flexible plate, such as a silicone flap, a rubber flap, etc. At this time, the flap partially constitutes the elastic component and is connected to the inner wall of the main passage by the elastic component. For example, the flap includes a circular body portion and a connecting portion extending outwardly from the body portion. The connecting portion is the elastic component. The body portion is connected to the inner wall of the main passage by the connecting portion. The body portion plays a role in blocking the reverse flow, and the connecting portion provides a bending elastic force for resetting the body portion after being opened.

[0060] In one embodiment of the present application, based on the foregoing embodiment, the check device is provided with an electric component, such as a motor. The output shaft of the motor is connected to the flap. The motor is controlled by the control unit of the clothes treatment apparatus and can actively open and close the flap according to the needs of the treatment program.

[0061] In one embodiment of the present application, a clothes treatment apparatus is provided, which includes the check device described in any of the foregoing embodiments. For example, refer to Figure 3 ,4 The laundry treating apparatus includes a water containing tub 400 and a washing tub 500 arranged in the water containing tub 400, the water containing tub 400 has an air inlet, one end of the main channel 100 is communicated with the air inlet, and the other end is arranged with a fan 700 and an electrostatic atomization device 600 capable of generating atomized particles, and the downflow fluid is the airflow carrying the atomized particles formed in the main channel 100 when the fan 700 works.

[0062] Specifically, the front side of the water containing tub 400 is provided with an air inlet, one end of the main channel 100 is connected with the air inlet, and the other end is arranged with a fan 700, one side of the fan 700 inhales air when the fan 700 works, and the other side blows out air, the electrostatic atomization device 600 has an air inlet 610 and an air outlet 620, the electrostatic atomization device 600 is installed at the other end of the main channel 100 corresponding to the air inlet side, the air inlet 610 of the electrostatic atomization device 600 is communicated with the outside space, and the air outlet 620 faces the air inlet side of the fan 700; When the fan 700 works, the outside air is sucked into the main channel 100, and when the outside air passes through the electrostatic atomization device 600, the atomized particles generated inside the electrostatic atomization device 600 are blown into the main channel 100, and the atomized particles are blown into the water containing tub 400 along with the airflow from the air inlet, because the water containing tub 400 and the washing tub 500 are communicated, the atomized particles will then enter the washing tub 500 to implement care for the clothes. Among them, the downflow fluid is the airflow carrying the atomized particles formed in the main channel 100 when the fan 700 works, and the upflow fluid is the washing fluid or foam overflowing from the washing tub 500 to the outside through the air inlet.

[0063] The reverse flow device of any of the preceding embodiments can more reliably achieve the reverse flow function of the reverse flow fluid, and avoid the influence of the reverse flow fluid on the output of the atomized particles and the working stability of the electrostatic atomization device.

[0064] Referring to Figure 3 The laundry treating apparatus has a detergent box 800, the detergent box 800 is used to put detergent into the water containing tub 400 and the washing tub 500 in the washing process, in the embodiment, the bypass channel 300 is communicated to the detergent box 800, and the reverse flow fluid is guided to the detergent box 800. In other embodiments, the laundry treating apparatus also has a drain valve, the drain valve is used to drain the washing water in the water containing tub in the dehydration process and the like, the bypass channel is communicated to the drain valve, the reverse flow fluid is guided to the drain valve to be directly drained, or the reverse flow device is arranged with two bypass channels, one of which is communicated to the detergent box, and the other of which is communicated to the drain valve, thereby enhancing the guiding ability of the reverse flow fluid.
