The existing clothes treatment device mainly sterilizes through a UV lamp. However, the UV lamp can only be installed above the door seal, and the distance from the clothes is too far, resulting in weak sterilization effect. CONTENT OF THE UTILITY MODEL

After the microbubbles enter the washing tub, they can be directly adsorbed on the surface of the clothing. As the gas inside the microbubbles dissolves and is compressed, the bubbles gradually shrink, forming high pressure inside, and eventually bursting. This generates instantaneous high-temperature and high-pressure shock waves and ultrasonic waves, thereby producing hydroxyl free radicals, which helps to further improve the cleaning effect and kill bacteria.

[0034] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0035] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] This application provides a garment processing device 100, such as a washing machine or washer-dryer combo, which can solve the problem of weak sterilization effect of existing garment processing devices 100. The following description will be provided in conjunction with the accompanying drawings.

[0037] Please see Figure 1 The clothing processing device 100 proposed in this application includes a washing tub 1, a water pump 2, a water inlet pipe, an electrolysis device 4, and a venturi tube 5. One end of the water inlet pipe is connected to the washing tub 1, and the other end is connected to the water pump 2. The electrolysis device 4 is disposed on the water inlet pipe and is used to electrolyze the water flowing through the electrolysis device 4. The venturi tube 5 is disposed on the water inlet pipe and is located downstream of the electrolysis device 4 in the direction of water flow.

[0038] In the garment processing equipment 100, there is an inlet water pipe and a water pump 2. The water pump 2 draws in washing water and drives the washing water to flow in the inlet water pipe, which then delivers the water to the washing tub 1. An electrolysis device 4, a venturi tube 5, and a premixing device 3 (mentioned later) are all installed on the inlet water pipe. The water flows through these devices or components in sequence before entering the washing tub 1. For ease of understanding, in some embodiments, when only the electrolysis device 4 and the venturi tube 5 are installed on the inlet water pipe, the electrolysis device 4, the venturi tube 5, the pipe connecting two adjacent devices, the pipe connecting the electrolysis device 4 and the water pump 2, and the pipe connecting the venturi tube 5 and the washing tub 1 together constitute the inlet water pipe.

[0039] Among them, the electrolysis device 4 can electrolyze water to form high-purity oxygen water. The high-purity oxygen water contains a series of substances with strong oxidation-reduction capabilities, such as hydroxyl radicals ·OH, ozone O3, oxygen monooxygen O, and hydrogen peroxide H2O2. It has an extremely high oxidation-reduction potential and can effectively kill and degrade bacteria, viruses, and organic pollutants in a very short time, achieving an extremely high sterilization rate (in some embodiments, the sterilization rate can even reach 99.99%), and can quickly remove odors.

[0040] Among them, the Venturi tube 5 is a pipeline system used to transport fluids such as liquids and gases, and its structure is as follows: Figure 5As shown, it is typically a T-shaped tube, consisting of a water pipe and an air inlet pipe 51. The interior of the water pipe forms a conduit for water flow, which is composed of an inlet section 52 and an outlet section 53. The diameter of the inlet section 52 gradually narrows in the direction of water flow, while the diameter of the outlet section 53 gradually increases. Therefore, the entire pipe has a shape that first narrows and then gradually widens in the direction of water flow. For ease of description, in this paper, the narrower section in the middle of the Venturi tube 5 (equivalent to the area where the inlet section 52 and the outlet section 53 are connected) is named the narrow section 54. One end of the air inlet pipe 51 is connected to the outside, and the other end is connected to the narrow section 54. When water flows through the Venturi tube 5, the narrow section 54 generates negative pressure, which draws air into the pipe through the air intake pipe 51, thus mixing the water and air and releasing a large number of microbubbles. The microbubbles can enter the washing tub 1 with the water flow. Since the water flow through the Venturi tube 5 has a certain pressure, when the microbubbles flow with the water, on the one hand, the gas inside the microbubbles will gradually dissolve, and on the other hand, the microbubbles themselves will also be subjected to compression force, which will cause the bubbles to gradually shrink, form high pressure inside, and eventually burst. When bursting, instantaneous high temperature and high pressure shock waves and ultrasonic waves will be formed around the microbubbles, thereby generating hydroxyl radicals.

[0041] In the garment treatment device 100 proposed in this application, an electrolysis device 4 and a venturi tube 5 are installed along the water flow direction on the water inlet pipe. The electrolysis device 4 electrolyzes the water to form high-purity oxygenated water with good sterilization and deodorization effects, which helps to improve the sterilization and deodorization effects on clothes; at the same time, the high-purity oxygenated water is mixed with air through the venturi tube 5 to form a large number of microbubbles, which helps to further improve the cleaning effect and the bactericidal effect.

[0042] To further improve the sterilization effect, in some embodiments, the garment treatment device 100 also includes a premixing device 3. The premixing device 3 is disposed on the water inlet pipe and is located downstream of the Venturi tube 5 in the direction of water flow. After being pressurized and forming microbubbles in the Venturi tube 5, the water enters the premixing device 3. The water pressure can promote the full dissolution of the gas in the water, making the formed bubbles smaller and denser, thereby having a better and stronger cleaning effect and sterilization effect.

[0043] In one specific embodiment, the premixing device 3 includes a first housing, within which a premixing chamber is formed. The premixing chamber has a first inlet and a first outlet. The first inlet communicates with the Venturi tube 5, and the first outlet communicates with the washing tub 1. The premixing device 3 is generally box-shaped, with an internal chamber where water and air can be premixed. Further, in some embodiments, the first housing is a cuboid structure, having a first sidewall and a second sidewall disposed opposite each other in its thickness direction. The first inlet and the first outlet are respectively disposed on the first and second sidewalls, such that the water flow direction is consistent with the thickness direction, which helps to further promote the pressurized premixing effect. It can be understood that the first housing is formed by six sidewalls, where the first and second sidewalls are the two largest rectangular sidewalls in terms of area, and the thickness direction refers to the direction from the first sidewall to the second sidewall.

[0044] It is understandable that other devices can be installed on the water inlet pipe, such as other devices with sterilization functions, or structural components with deodorization functions, etc. In actual application, adjustments can be made as needed.

[0045] In some embodiments, the washing tub 1 has a door seal 11. The door seal 11 refers to the ring-shaped structure forming the opening of the washing tub 1. For example... Figure 2 As shown, the opening of the washing tub 1 faces forward, and the door seal 11 has a portion near the bottom, referred to as the lower part. Since microbubbles are prone to bursting during transport, resulting in a smaller number of microbubbles ultimately contacting the clothes, placing the connection between the water inlet pipe and the washing tub 1 on the tub wall would lengthen the water inlet pipe, occupying more installation space and increasing component costs. Furthermore, it would cause a large number of microbubbles to dissipate during transport, affecting the sterilization effect. However, placing the connection between the water inlet pipe and the washing tub 1 on the upper part of the door seal 11 would provide a relatively long head, and most of the water flow would easily flow down along the door (installed on the door seal 11 to cover the washing tub 1), thus accelerating the bursting of microbubbles. Therefore, in this embodiment of the application, a water inlet hole 111 is provided on the lower part, and the water inlet pipe is connected to the water inlet hole 111. In this way, water can enter the washing tub 1 from below the door seal 11, so as to contact the clothes immediately. This helps to reduce the water inlet head, increase the water inlet velocity and flow rate, thereby reducing the amount of microbubbles that break before contacting the clothes and increasing the number of microbubbles that contact the clothes.

[0046] One or more electrolysis devices 4 can be installed. When multiple electrolysis devices 4 are installed, they are arranged sequentially along the water flow direction, which helps to increase the proportion of high-purity oxygen water in the water flow and improve the sterilization and deodorization effects.

[0047] Please see Figure 3 and Figure 4 In one specific embodiment, the electrolysis device 4 includes a second housing 41 and an electrolysis module 42. The second housing 41 has a second inlet and a second outlet, and the second outlet is connected to the venturi tube 5. The electrolysis module 42 is disposed inside the second housing 41 and includes a cathode plate 421, a diaphragm 422, and an anode plate 423 stacked together. The diaphragm 422 is made of insulating material to prevent direct contact between the anode plate 423 and the cathode plate 421. The cathode plate 421, diaphragm 422, and anode plate 423 are arranged parallel to each other and stacked sequentially. The arrangement of the electrolysis module 42 is not limited in this application. In some embodiments, the plate surface of the electrolysis module 42 is perpendicular to the direction from the second inlet to the second outlet, so that water can flow sequentially through the cathode plate 421, diaphragm 422, and anode plate 423 to ensure the electrolysis function of the cathode plate 421 and anode plate 423. Furthermore, in some embodiments, the cathode plate 421 faces the second inlet, i.e., towards the incoming water, while the anode plate 423 is located on the side of the cathode plate 421 away from the second inlet and close to the second outlet. In this way, the impact of water flow on the anode plate 423 can be reduced, the antioxidant performance of the anode plate 423 can be improved, and its service life can be extended.

[0048] In some embodiments, the cathode plate 421 and the anode plate 423 are further provided with a plurality of through holes 43 to allow water to flow through.

[0049] In addition, in some embodiments, the cathode plate 421 has a cathode terminal 44 extending out of the second housing 41, and the anode plate 423 has an anode terminal 45 extending out of the second housing 41. The anode terminal 45 and the cathode terminal 44 can be electrically connected to the power supply module.

[0050] In some embodiments, the second housing 41 is generally box-shaped, with an internal receiving cavity. The second housing 41 has a first inner wall and a second inner wall 412 disposed opposite to each other, and a frame 411 disposed between the first inner wall and the second inner wall 412. The first inner wall, the second inner wall 412, and the frame 411 together define the receiving cavity. The first inner wall is disposed opposite to the cathode plate 421, and the second inner wall 412 is disposed opposite to the anode plate 423. In some embodiments, a first support member 46 is provided on the first inner wall. The first support member 46 is supported between the cathode plate 421 and the first inner wall, so that the cathode plate 421 is spaced apart from the first inner wall. On the one hand, it can support and fix the cathode plate 421. On the other hand, it can maintain a certain space between the cathode plate 421 and the first inner wall, so that the water entering the receiving cavity can retain a certain residence time in the electrolysis device 4, and make more sufficient contact with the electrolysis module 42 to increase the proportion of high-purity oxygen water. One or more first support members 46 can be provided. When multiple first support members 46 are provided, they are arranged side by side and spaced apart between the first inner wall and the cathode plate 421. In other embodiments, a second support member is provided on the second inner wall 412. The second support member is supported between the anode plate 423 and the second inner wall 412, so that the anode plate 423 and the second inner wall 412 are spaced apart. This can support and fix the anode plate 423, and also allow the water entering the receiving cavity to have more sufficient contact with the electrolysis module 42. When the second outlet is formed on the second inner wall 412, it can also facilitate the discharge of water in the receiving cavity from the second outlet. One or more second support members can be provided. When multiple second support members are provided, they are arranged side by side and spaced apart between the second inner wall 412 and the anode plate 423.

[0051] Furthermore, in one embodiment, a third support member 47 is provided on the frame 411, and the third support member 47 is supported between the frame 411 and the electrolysis module 42, so that the frame 411 and the electrolysis module 42 are spaced apart. In this way, water entering the receiving cavity can also flow through the gap between the frame 411 and the electrolysis module 42, which can ensure the flow rate and volume of water while achieving electrolytic sterilization. One or more third support members 47 can be provided. When multiple third support members 47 are provided, they can surround the electrolysis module 42 and be spaced apart.

[0052] It is understood that only one of the first support member 46, the second support member, and the third support member 47 can be set, or any two or three of them can be set.

[0053] In the Venturi tube 5, the air inlet pipe 51 has an air inlet 511 at the end away from the water pipe. A sealing element 55 is installed inside the air inlet pipe 51. The sealing element 55 can reciprocate along the length of the air inlet pipe 51, thus having both a sealed and an open position. When the sealing element 55 is in the sealed position, it is located at the air inlet 511, blocking outside air from entering the water pipe. When the sealing element 55 is in the open position, there is a gap between the sealing element 55 and the air inlet 511, allowing outside air to enter the water pipe and mix with water to form microbubbles. In practical applications, when water intake is required, the sealing element 55 is driven to the open position, which can form microbubbles to improve sterilization and cleaning capabilities. When water intake stops, the sealing element 55 is driven to the closed position to prevent residual water in the water pipe from flowing out of the air inlet 511. In some embodiments, the sealing element 55 can be a steel ball or a rubber stopper. It should be noted that the diameter of the sealing element 55 is greater than or equal to the inner diameter of the air inlet 511 and smaller than the inner diameter of the air intake pipe 51, thereby ensuring that it can seal the air inlet 511 when in the closed position, and that a gap is left between the sealing element 55 and the air intake pipe 51 for air to pass through when in the open position.

[0054] To enable the reciprocating movement of the sealing element 55, an elastic element 56 is also provided inside the air intake pipe 51. The elastic element 56 is connected between the sealing element 55 and the inner wall of the air intake pipe 51; specifically, as shown... Figure 5 As shown, the air intake pipe 51 has a connecting end that communicates with the narrow section 54. In this embodiment, the elastic element 56 is a spring. One end of the spring is connected to the sealing element 55, and the other end is connected to the connecting end. When no water flows through the water pipe, the spring extends freely, and the sealing element 55 is in the blocking position. When water flows through the water pipe, the narrow section 54 forms a negative pressure, thereby driving the spring to compress. The steel ball moves away from the air intake 511, and the air intake 511 is opened.

[0055] Furthermore, the water pump 2 can be a fixed-frequency pump or a variable-frequency pump. In some embodiments, a variable-frequency pump is used, which allows the rotation speed to be adjusted, thereby obtaining higher flow rates and volumes, which helps to draw in more air, forming smaller and denser microbubbles, thereby improving the cleaning and sterilization effects.
