[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0036] This application provides a drainage component for a door seal. For an example, please refer to [link to example]. Figure 1 , Figure 1 This is a schematic diagram of the structure of the drainage assembly provided in an embodiment of this application. The drainage assembly 100 is applied to a garment processing device, and a drain outlet is provided at the bottom of the door seal. The drainage assembly 100 includes a first venturi tube 110 and a drainage pipe 120.
[0037] The first venturi tube 110 includes a first suction port 111 and a first outlet 112. The first suction port 111 is used to connect with the drain outlet of the door seal to extract water from the door seal. The inlet end 121 of the drain pipe 120 is connected with the first outlet 112 to discharge the water extracted from the first venturi tube 110.
[0038] It's important to note that a Venturi tube is a pipe used to transport fluids, including a constricted section that is tapered. According to the law of conservation of flow, in a stable, incompressible fluid system, the volumetric flow rate of the fluid across any cross-section is constant. Therefore, in a Venturi tube, the flow rate of liquid from one end to the other is constant throughout the entire pipe. On the other hand, according to the law of conservation of energy, energy is always conserved. In a Venturi tube, pressure energy and potential energy are converted into each other during the flow, but their total sum remains constant. This means that changes in the pressure or velocity of the liquid in the pipe lead to energy conversion, thus affecting the flow of the liquid.
[0039] Based on the above principle, when the water in the door seal passes through the first venturi tube 110, it will be forced through a narrower pipe, thereby increasing the speed of the detergent mixture and forming a negative pressure area at the inlet end of the first venturi tube 110. This allows the water in the door seal to be drawn into the first venturi tube 110 through the suction port 111, and then discharged into the drain pipe 120 through the first outlet 112.
[0040] Optional, see below Figure 2 , Figure 2 This is a cross-sectional view of a first venturi tube provided in an embodiment of this application. The first venturi tube 110 has a constriction section 113 whose cross-sectional area of the flow channel gradually decreases along the direction of water flow, and a suction port 111 connected to the drain outlet of the door seal is provided on the constriction section 113; the first venturi tube 110 also has an expansion section 114 whose cross-sectional area of the flow channel gradually increases along the direction of water flow, the constriction section 113 and the expansion section 114 are arranged sequentially along the direction of water flow, and the suction port 111 is located at the connection between the constriction section 113 and the expansion section 114.
[0041] The drainage component 100 for the door seal provided in this application embodiment can achieve negative pressure suction of moisture inside the door seal by adding a first Venturi tube 110 to the drainage pipe 120 of the door seal, thereby reducing moisture residue on the door seal, preventing bacteria from growing on the door seal and producing odors, and affecting the health and user satisfaction of the user.
[0042] In some embodiments, as Figure 1 The drainage pipe 120 includes a first water outlet 122, and the drainage assembly also includes a drainage pump 130. The drainage pump 130 includes an inlet 131 and a first outlet 132. The inlet 131 is connected to the first water outlet 122 and is used to receive water flowing out of the drainage pipe 120. The drainage pump 130 is adapted to drive water through the first outlet 132 to be discharged to the outside of the clothing processing equipment.
[0043] The drain pump 130 can be a drain pump from the washing tub of the garment processing equipment, reused for draining the door seal, or it can be a separately added drain pump for draining the door seal. Understandably, the suction effect of the first venturi tube 110 can accelerate the entry of residual water in the door seal into the drain pump, and also help solve the problem of abnormal noise caused by gas-liquid mixing at the start of drainage or by the drain motor running idle.
[0044] In some embodiments, please refer to Figure 3 , Figure 3 This is another structural schematic diagram of the drainage assembly provided in the embodiments of this application. The drainage pipe 120 also includes a second water outlet 123, and the drainage assembly 100 also includes a second venturi tube 140 and a flushing pipe 150. The second venturi tube 140 includes a second suction port 141 and a second water outlet 142. The second suction port 141 is connected to the second water outlet 123 and is used to draw water from the drainage pipe 120. One end of the flushing pipe 150 is connected to the second water outlet 142, and the other end is used to flush and clean the door seal.
[0045] It should be noted that during the use of the garment processing equipment, foam, dirt, etc., may easily remain on the upper part of the door seal. By recirculating the water discharged from below the door seal to the top of the door seal for rinsing, the overall cleanliness of the door seal can be improved. When rinsing the door seal using the flushing pipe 150, the first outlet 122 of the drain pipe 120 can be closed to prevent water in the drain pipe 120 from entering the drain pump 130, and the second outlet 123 can be kept open to allow water in the drain pipe 120 to be drawn into the flushing pipe 150 through the second venturi tube 140. Optionally, a first valve body can be installed between the inlet 121 and the first outlet 122 of the drain pipe 120, and a second valve body can be installed between the inlet 121 and the second outlet 123. When the door seal needs to be rinsed, the first valve body is closed and the second valve body is opened; when the water in the door seal needs to be drained, the first valve body is opened and the second valve body is closed.
[0046] In one parallel embodiment, please refer to Figure 4 , Figure 4 This is another structural schematic diagram of the drainage assembly provided in the embodiments of this application. The drainage pump 130 also includes a second outlet 133, and the drainage assembly 100 also includes a flushing pipe 150. One end of the flushing pipe 150 is connected to the second outlet 133, and the other end faces the door seal. The drainage pump 130 is adapted to drive water to flow into the flushing pipe 150 through the second outlet 133. The flushing pipe 150 is used to flush and clean the door seal.
[0047] It should be noted that when flushing the door seal using the flushing pipe 150, the second outlet 133 of the drain pump 130 can be opened to allow water from the drain pump 130 to enter the flushing pipe 150 through the second outlet 133. Optionally, a first valve body at the second outlet 133 can be used to control the flushing of the door seal or stop the flushing process by controlling the opening and closing of the first valve body.
[0048] In some embodiments, the drainage assembly 100 further includes a spray head 160, which is connected to the flushing end of the flushing pipe 150 for spraying. Optionally, the spray head 160 has multiple spray nozzles, which are oriented towards the door seal. This increases the flushing range and water pressure on the door seal, thereby improving cleaning efficiency.
[0049] In some embodiments, a flushing port is provided at the top of the door seal, and the flushing end of the flushing pipe 150 is fixedly inserted into the flushing port. Preferably, the flushing pipe 150 is sealed to the inner wall of the door seal that forms the flushing port.
[0050] To prevent contaminants in the water from entering the first venturi tube 110 and causing blockage, or from entering the drain pump 130 and causing blockage, a filter element (not shown) can be installed on the door seal. This filter element filters the water flowing from the drain outlet on the door seal to the first suction port 111. Optionally, the filter element includes multiple layers of filter screens stacked along the water flow direction. The through-holes of adjacent filter screens can be staggered along the water flow direction.
[0051] The drainage component 100 for the door seal provided in this application embodiment can achieve negative pressure suction of moisture inside the door seal by adding a first Venturi tube 110 to the drainage pipe 120 of the door seal, thereby reducing moisture residue on the door seal, preventing bacteria from growing on the door seal and producing odors, and affecting the health and user satisfaction of the user.
[0052] This application also provides a garment processing device, for example, please refer to [link to example]. Figures 5-6 , Figure 5 This is a schematic diagram of a garment processing device provided in an embodiment of this application. Figure 6 This is another structural schematic diagram of the garment processing device provided in an embodiment of this application. The garment processing device 10 can be a washing machine, shoe washing machine, washer-dryer combo, or other equipment. The garment processing device 10 includes a housing 200, a washing tub (not shown), a door seal 300, and the aforementioned drainage assembly 100.
[0053] The door seal 300 is installed on the housing 200, and a drain outlet 310 is provided at the bottom of the door seal 300; the drain assembly 100 is located inside the housing 200 and is connected to the drain outlet 310 of the door seal 300 to drain the water inside the door seal 300.
[0054] The clothing processing device 10 provided in this application embodiment has a door seal 300 connected to a drainage component 100. By adding a first Venturi tube 110 to the drainage pipe 120 of the door seal, negative pressure suction of moisture inside the door seal 300 can be achieved, reducing moisture residue on the door seal 300, preventing bacteria from growing on the door seal 300 and producing odors, thus affecting the user's health and user satisfaction.
