Description

Technical Field

[0001] The present application relates to the technical field of clothing care, and in particular to a microbubble generating device and a clothing care device. Background Art

[0002] Microbubble technology is being applied in the clothing care field. Compared to conventional bubbles, microbubbles offer significant advantages in terms of contact area and contact time between the gas and liquid phases. Due to their larger contact area, microbubbles possess excellent adsorption properties. Furthermore, because they readily generate hydroxyl groups, they have a strong oxidizing effect, which can have a bactericidal effect. Furthermore, microbubble technology can improve clothing cleaning performance, reduce chemical residues, and minimize clothing damage.

[0003] Currently, there are multiple methods for generating microbubbles, but due to their varying technical principles, each has its own advantages and disadvantages, resulting in only a few being applicable to clothing care. For example, the dissolved air release method can produce high-density, small-sized bubbles, but this method requires high energy consumption and pressure, and is complex and requires high equipment requirements.

[0004] Therefore, there is an urgent need to provide a microbubble generating device to solve at least one of the above technical problems. Utility Model Content

[0054] Figure 1Figure 2 shows a schematic diagram of the structure of a microbubble generating device applied to a washing machine 1. The microbubble generating device 100 is located at the top of the outer drum and is fixedly connected to the housing of the washing machine 1. The water inlet of the microbubble generating device 100 is connected to the tap water supply via a solenoid valve (not shown in the figure), and the water outlet is connected to the detergent box of the washing machine 1 via a rubber hose. The microbubbles generated by the microbubble generating device 100 provided in this embodiment of the application enter the detergent box, fully mix with the detergent, and then enter the inner drum.

[0055] The washing machine 1 provided in the embodiment of the present application includes but is not limited to a pulsator washing machine, a drum washing machine, and a clothes dryer. Thoroughly mixing the microbubbles generated by the microbubble generating device 100 with detergent can not only reduce the amount of detergent used, but also reduce detergent residue on clothes, and save water and electricity energy used for clothing care.

[0056] Figure 2 : shows a schematic diagram of the three-dimensional structure of the microbubble generating device 100 provided in an embodiment of the present application, Figure 2 The overall shape of the microbubble generating device 100 shown in FIG. 1 is similar to a rectangular parallelepiped structure. However, the shape of the microbubble generating device 100 is not limited to this, and may be similar to a cylinder, for example. This is not specifically limited in the present embodiment. Furthermore, the microbubble generating device 100 provided in the present embodiment is not limited to application in a washing machine 1 but can also be applied to other devices that require the use of microbubbles.

[0057] Specifically, if Figure 2 、 Figure 3a 、 Figure 3b and Figure 3c As shown, the microbubble generating device 100 provided in the embodiment of the present application includes a tank body 10, a water inlet connector 20, a water outlet connector, an electromagnetic ventilation valve 50 and at least two flow-inducing components 40. Among them, the tank body 10 has a water inlet 111 and a water outlet 121, and a generating chamber 10a is formed inside the tank body 10, and the water inlet 111 and the water outlet 121 are both connected to the generating chamber 10a. The water inlet connector 20 is connected to the water inlet 111 of the tank body 10 and is connected to the tap water, and the water outlet connector is connected to the water outlet 121 of the tank body 10 and is connected to the detergent box of the washing machine 1. At least two flow-inducing components 40 are connected to the inner wall of the tank body 10 and are staggered in the generating chamber 10a.

[0058] The electromagnetic ventilation valve 50 is connected to the upper end of the first tank body 110. After the microbubble generating device 100 has been operating for a period of time, the air within the tank body 10 will be depleted, and microbubbles can no longer be generated. The electromagnetic ventilation valve 50 is then opened to replenish air within the generating chamber 10a. Furthermore, when the microbubble generating device 100 stops operating, the electromagnetic ventilation valve 50 can be used to assist in the removal of liquid trapped within the generating chamber 10a. It should be noted that the electromagnetic ventilation valve 50 is a one-way passage, meaning that only air can enter the generating chamber 10a, while the air and liquid within the generating chamber 10a cannot be discharged, thereby significantly reducing the risk of leakage.

[0059] In the above-mentioned microbubble generating device 100, water flows into the generating chamber 10a from the water inlet 111 on the tank body 10. Under the action of at least two agitators 40, the water flow can repeatedly impact the inner wall of the tank body 10 and the agitators 40, forming small bubbles under the action of shear force. This can increase the gas-liquid contact area and thereby improve the solubility of air in water. In addition, the flow rate difference and height difference of the inlet and outlet water flow will form a water seal at the water outlet 121, thereby gradually increasing the pressure in the generating chamber 10a and forming a high-pressure chamber, further increasing the solubility of air.

[0060] In an optional embodiment, the tank body 10 includes a first tank body 110 and a second tank body 120, the water inlet 111 is located in the first tank body 110, and the water outlet 121 is located in the second tank body 120. During use, the first tank body 110 is located above the second tank body 120, and the water outlet 121 is located at the bottom end of the side wall of the second tank body 120, which can discharge all the water in the generating chamber 10a.

[0061] The first tank body 110 and the second tank body 120 are connected by a plurality of first fasteners, and a seal 130 is connected between the first tank body 110 and the second tank body 120 so that the first tank body 110 and the second tank body 120 are sealed. As an example, the seal 130 is a rubber sealing ring, and the first fastener is an M4 screw, but it is of course not limited to this. In addition, the internal pressure of the tank body 10 is relatively high, and it is in a high-frequency vibration state during actual operation. There may be a situation where hard contact occurs with surrounding structural parts, and the tank body 10 itself may also be in a resonant state. A first reinforcing rib 140 is provided on the outer wall of the tank body 10, and the first reinforcing rib 140 can improve the structural strength of the tank body 10.

[0062] Furthermore, if Figure 3b As shown, the first tank body 110 is provided with a snap-fit ​​protrusion 112, and the second tank body 120 is provided with a snap-fit ​​groove 122 matching the snap-fit ​​protrusion 112, and the sealing member 130 is located between the snap-fit ​​protrusion 112 and the snap-fit ​​groove 122 to further improve the sealing connection effect between the first tank body 110 and the second tank body 120.

[0063] Figure 3b A cross-sectional view of the microbubble generating device 100 is shown, and the first and second agitation plates 410, 420, which are staggered and included in the agitation member 40, are also shown. The first agitation plate 410 is connected to the first tank body 110, and the second agitation plate 420 is connected to the second tank body 120. Under the blocking action of the first and second agitation plates 410, 420, and the inner wall of the tank body 10, the water flow repeatedly hits the inner wall of the tank body 10, the first agitation plate 410, and the second agitation plate 420 to form more microbubbles.

[0064] The flow-stimulating member 40 may further include a greater number of flow-stimulating plates, which may be configured based on the size of the tank body 10 , and is not specifically limited in the embodiment of the present application.

[0065] In an alternative embodiment, if Figure 2 As shown, the water inlet 111 is located on the first side wall 11 of the first tank body 110, in the first direction, i.e. Figure 2 In the direction of arrow s1 shown in FIG, the water inlet 111 is located between the first rapids plate 410 and the second side wall 12 of the first tank body 110 , and the first direction is perpendicular to the axis direction of the water inlet 111 .

[0066] Furthermore, the first side wall 11 corresponds to the long side of the first can body 110 , and the second side wall 12 corresponds to the short side of the first can body 110 . Figure 2 The microbubble generating device 100 shown in the figure is similar to a rectangular parallelepiped, and the water inlet 111 is provided on the first side wall 11 corresponding to the long side of the first tank body 110. This allows the water flow to enter the generating chamber 10a from the water inlet 111 and then collide with the inner wall of the tank body 10 and the surface of the first rapids plate 410 in a relatively short time, that is, when the water flow is at a relatively high speed, thereby improving the impact effect of the water flow and thereby increasing the solubility of gas.

[0067] Please refer to Figure 3c , in the first direction, i.e. Figure 3c In the direction of arrow s1, the second agitator 420 is located between the first agitator 410 and the water outlet 121 of the second tank 120. Both the first agitator 410 and the second agitator 420 increase the water flow rate and increase the number of small bubbles. The second agitator 420 further increases the water flow rate, ensuring a high flow rate for the water entering the water outlet 121.

[0068] Furthermore, the structures of the first excitation plate 410 and the second excitation plate 420 may be the same or different, but both the first excitation plate 410 and the second excitation plate 420 are provided with a narrow and long first through hole 40a. After the water in the generating chamber 10a flows through the first through hole 40a, the water flow velocity can be increased, thereby generating a larger number of small bubbles.

[0069] The first through hole 40a can be a gap formed between two adjacent first excitation plates 410, or a hole provided on the first excitation plate 410, and is not specifically limited in this embodiment of the present application. Furthermore, the specific structure of the first excitation plate 410 and the second excitation plate 420 is not specifically limited in this embodiment of the present application and can be set as needed to increase the water flow velocity and generate a larger number of small bubbles.

[0070] Preferably, in the first direction, the water inlet 111 and the water outlet 121 of the tank body 10 are located at the two ends of the tank body 10 or close to the two ends of the tank body 10, so that the water flow can obtain a longer flow path after entering the generating chamber 10a, thereby generating more bubbles.

[0071] In an alternative embodiment, if Figure 3c As shown, a plurality of second reinforcing ribs 40 b are provided on the first excitation plate 410 and the second excitation plate 420 to improve the impact resistance of the first excitation plate 410 and the second excitation plate 420 and further ensure the structural stability of the microbubble generating device 100 .

[0072] Please refer to Figure 2 、 Figure 4a 、 Figure 4b 、 Figure 5a and Figure 5b The water outlet joint includes a first conversion joint 31 and a second conversion joint 32. The first conversion joint 31 is connected to the water outlet 121 of the second tank body 120 by a threaded connection, and the first conversion joint 31 is a venturi tube. A plurality of venturi tube-type channels 31a are arranged inside the first conversion joint 31. The channels 31a are composed of an inlet section 311, a contraction section 312 and an expansion section 313. The water flow from the generating chamber 10a into the plurality of venturi tube-type channels 31a is equivalent to a large-section water flow being squeezed into a plurality of small-section venturi tube-type channels 31a. When the water flows through the inlet section 311, the water flow velocity increases rapidly. When the water flows in the Venturi tube-type channel 31a, it passes through the inlet section 311, the contraction section 312 and the expansion section 313 in sequence. The flow area from the inlet section 311 to the contraction section 312 gradually decreases, and the flow area from the contraction section 312 to the expansion section 313 gradually increases. The flow velocity and pressure of the water flow will change accordingly, and negative pressure will be generated at the contraction section 312 and the expansion section 313, which will reduce the air solubility of the water body and precipitate the air from the solute state to form microbubbles. In addition, the small bubbles generated in the generating chamber 10a will be broken into smaller microbubbles when passing through the Venturi tube-type channel 31a.

[0073] The number of the venturi tube channels 31 a provided inside the first conversion joint 31 is set according to needs and is not specifically limited in the embodiment of the present application.

[0074] The second conversion joint 32 is connected to the end of the first conversion joint 31 . The inner cavity of the second conversion joint 32 is connected to the third agitator 321 and the bubbling piece 322 . The water discharged from the first conversion joint 31 flows through the third agitator 321 and then hits the bubbling piece 322 .

[0075] It can be understood that the water flow with microbubbles generated by the action of the agitator 40 in the generating chamber 10a forms a water flow with more microbubbles and smaller-sized microbubbles after passing through the first conversion joint 31, and then further contains more microbubbles and smaller-sized microbubbles in the water flow under the action of the third agitator plate 321 and the bubbling part 322 of the second conversion joint 32.

[0076] Specifically, the third rapids plate 321 is provided with at least one second through hole 3211, and the bubble generating member 322 includes a plurality of stacked filter screens. The water discharged from the first conversion joint 31 can increase the flow rate of the water flow after passing through the second through hole 3211. The faster flow of water colliding with the multi-layer filter screens can generate a larger number of microbubbles and separate the original microbubbles into smaller microbubbles.

[0077] The bubbler net is cylindrical in shape to match the shape of the second conversion joint 32, but is not limited to this structure. Multiple layers of 150-mesh filter screens are installed within the bubbler net. The number of filter screens can be 5, 6, or 7, etc., to minimize the size and increase the number of ejected microbubbles. The total number of bubbler nets is 800 to 1000 to ensure the size and number of ejected microbubbles and the flow rate of the water. If the total number of bubbler nets is less than 800, the size of the ejected microbubbles will not be sufficiently fine. If the total number of bubbler nets is greater than 1000, the resistance to the water flow will be too great, affecting the flow rate.

[0078] The second adapter 32 and the first adapter 31 can be connected via an adapter 323 to ensure a secure connection, for example, by threading. Furthermore, a gasket 325 is connected to the inner cavity of the second adapter 32. The gasket 325 is connected to the third damper 321 to ensure a sealed connection between the inner cavity wall of the third damper 321 and the second adapter 32. This further ensures that water flows only through the second through-hole 3211 of the third damper 321, thereby increasing the water flow rate.

[0079] The second conversion joint 32 has a conversion port 324 at one end away from the first conversion joint 31 . The conversion port 324 can be connected to a rubber tube, and the other end of the rubber tube is connected to the detergent box.

[0080] Please refer to 6a and 6b. The middle part of the water inlet connector 20 is a threaded structure 21, and the water inlet connector 20 is connected to the water inlet 111 of the first tank body 110 through the threaded structure 21. The end of the water inlet connector 20 close to the water inlet 111 is a throat-type structure 23, that is, the flow channel area is sharply reduced, so that the water flow entering the generating chamber 10a has a certain initial velocity. The other end of the water inlet connector 20 is provided with a snap-on structure 22. After the snap-on structure 22 is connected to the rubber tube, it is fastened with a hoop at the snap-on position to prevent water from flowing. The other end of the rubber tube can be directly connected to a faucet or a booster pump. The connection of the rubber tube to the booster pump can increase the flow rate and pressure of the water flow, and can improve the foaming effect of the micro-bubble generating device 100, thereby improving the cleaning ability of the washing machine 1.

Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described.
