[0058] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0059] Reference below Figure 1-Figure 21 The delivery device 400 according to an embodiment of the present invention is described.

[0060] like Figure 1-Figure 4 As shown, the dispensing device 400 according to the embodiment of the present invention comprises: a detergent box 300 and a micro-bubble generator 100, wherein the detergent box 300 defines a detergent cavity for containing detergent, and the detergent box 300 is provided with a water inlet manifold 51 on the outside, and a water inlet hole is provided on the wall of the water inlet manifold 51. The micro-bubble generator 100 is connected to the water inlet hole through a micro-bubble pipe 52, so that the micro-bubble water produced by the micro-bubble generator 100 is introduced into the water inlet manifold 51. Among them, a water stopper 53 is provided in the water inlet manifold 51, and at least a part of the water stopper 53 is directly opposite to the water inlet hole.

[0061] According to the dispensing device 400 of the embodiment of the present invention, by providing a water blocking member 53 in the water inlet manifold 51, the high-pressure microbubble water entering the water inlet manifold 51 from the microbubble connecting pipe 52 can be effectively controlled to prevent the high-pressure microbubble water from overflowing from the front side of the detergent box 300, which not only avoids the waste of water resources, ensures that the high-pressure microbubble water and the detergent flowing out of the detergent box 300 can be fully and efficiently mixed, thereby improving the washing efficiency and further improving the cleaning ratio, but also ensures the user experience.

[0062] According to one embodiment of the present invention, the water retaining member 53, the water inlet manifold 51 and at least a portion of the detergent box 300 are integrally formed, thereby reducing the number of parts, ensuring the compact structure of the dispensing device 400, and making the dispensing device 400 more convenient to assemble and disassemble.

[0063] like Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the water inlet hole is arranged on the peripheral wall of the water inlet manifold 51, and the water retaining member 53 includes a longitudinal water retaining portion 531 and a transverse water retaining portion 532. The longitudinal water retaining portion 531 is directly opposite to the water inlet hole, and the longitudinal water retaining portion 531 is spaced apart from the water inlet hole, and the transverse water retaining portion 532 is arranged on the side of the longitudinal water retaining portion 531 facing the water inlet hole, and the position of the transverse water retaining portion 532 is higher than the position of the water inlet hole.

[0064] Therefore, the horizontal water retaining portion 532 can block the high-pressure microbubble water entering the water inlet manifold 51, thereby achieving a water retaining effect and preventing the high-pressure microbubble water from splashing upward and overflowing from the front side of the detergent box 300, and the longitudinal water retaining portion 531 can also play a guiding role, so that the high-pressure microbubble water can flow out of the water inlet manifold 51 along the longitudinal water retaining portion 531.

[0065] In some embodiments, Figure 3-Figure 5 As shown, one end of the transverse water retaining portion 532 is connected to the longitudinal water retaining portion 531, and the other end of the transverse water retaining portion 532 is provided with a downwardly bent flange portion 533. By providing the flange portion 533, the high-pressure microbubble water entering the water inlet manifold 51 can be further blocked, and the high-pressure microbubble water can be more effectively prevented from splashing upward into the detergent box 300.

[0066] In some embodiments, the longitudinal water retaining portion 531 is arranged along the axial direction of the water inlet manifold 51 (eg Figure 3 or the longitudinal water retaining portion 531 is arranged to be inclined relative to the axial direction of the water inlet manifold 51.

[0067] For example, the longitudinal water retaining part 531 can be formed as a plate extending along the axial direction of the water inlet manifold 51 or arranged obliquely relative to the axial direction of the water inlet manifold 51. In this embodiment, the longitudinal water retaining part 531 is provided with a positioning column 55 extending along its length direction, and one end of the positioning column 55 extends to the transverse water retaining part 532, which can not only ensure the structural strength of the water retaining part 53, but also facilitate its fixing.

[0068] In some embodiments, Figure 5As shown, the longitudinal water retaining portion 531 has a water passing notch 54, and the opening of the water passing notch 54 faces downward. The water passing notch 54 connects the spaces on both sides of the longitudinal water retaining portion 531, and a portion of the high-pressure microbubble water entering the water inlet manifold 51 flows downward along one side of the longitudinal water retaining portion 531 under the obstruction of the transverse water retaining portion 532 and the flange portion 533, and another portion of the high-pressure microbubble water directly impacts the longitudinal water retaining portion 531, and then flows downward along one side of the longitudinal water retaining portion 531, and another portion of the high-pressure microbubble water passes through the water passing notch 54 and flows downward from the space on the other side of the longitudinal water retaining portion 531, and finally the high-pressure microbubble water is led out of the water inlet manifold 51.

[0069] Therefore, by setting the water-passing gap 54, the contact area between the high-pressure microbubble water and the water retaining member 53 can be reduced, thereby reducing the impact force of the high-pressure microbubble water on the longitudinal water retaining portion 531, avoiding damage to the water retaining member 53, and thus extending the service life of the water retaining member 53.

[0070] like Figure 2 and Figure 3 As shown, according to a further embodiment of the present invention, a peripheral wall of the water inlet manifold 51 is provided with a connecting joint 511 protruding outward, and the connecting joint 511 defines a water inlet hole, wherein one end of the microbubble connecting pipe 52 is sleeved on the connecting joint 511, and the other end of the microbubble connecting pipe 52 is connected to the microbubble generator 100, for example, the microbubble connecting pipe 52 is connected to the connecting joint 511 by an adjustable hoop or a cable tie, and the connection is convenient and more reliable.

[0071] According to one embodiment of the present invention, Figure 2 and Figure 6 As shown, a slot 3141 is provided at the bottom of the detergent box 300, and the microbubble pipe 52 is suitable for sliding into the slot 3141 from a side opening of the slot 3141, thereby fixing the microbubble pipe 52 at the bottom of the detergent box 300, avoiding the microbubble pipe 52 from shaking significantly and affecting the connection effect, thereby ensuring the reliability of the microbubble pipe 52.

[0072] In some embodiments, a guide surface 3142 is provided at the opening, which gradually extends from the outside of the slot 3141 to the inside of the slot 3141 toward the center of the opening, so as to facilitate sliding the microbubble tube 52 from the opening into the slot 3141 for easy installation.

[0073] In some embodiments, Figure 6As shown, a hook 314 is provided at the bottom of the detergent box 300, and the hook 314 defines a slot 3141, wherein a reinforcing rib 3143 is provided on the side of the hook 314 facing away from the slot 3141, and one end of the reinforcing rib 3143 extends to the bottom of the detergent box 300. By providing the reinforcing rib 3143 on the side of the hook 314 facing away from the slot 3141, the structural strength of the hook 314 can be ensured, thereby ensuring the installation reliability of the microbubble pipe 52.

[0074] In order to well integrate the microbubble generator 100 with the detergent box 300, the microbubble generator 100 can be installed on the detergent box 300, and the microbubble generator 100 can be arranged substantially flush with the top of the detergent box 300 and the microbubble generator 100 can be arranged substantially flush with the bottom of the detergent box 300.

[0075] like Figure 7 As shown, according to one embodiment of the present invention, the air dissolving tank of the microbubble generator 100 is further provided with a mounting ear 192, and the mounting ear 192 is used to connect to the body of the clothing processing device, which can further improve the installation reliability of the integrated component.

[0076] In some embodiments, the microbubble generator 100 has a plurality of fixing ears 191, each of which is connected to the detergent box 300. For example, each fixing ear 191 is connected to the detergent box 300 by a fastener inserted through a connecting hole. This arrangement can ensure the reliability of the integrated connection between the microbubble generator 100 and the detergent box 300. After the integrated connection, the anti-seismic performance will be significantly enhanced. In addition, the microbubble generator 100 and the detergent box 300 are both water-passing components, and combining the two in an integrated volume is conducive to improving the stability of the overall structure.

[0077] In some embodiments, each fixing ear 191 is provided with a connecting hole, and the center lines of at least a portion of the multiple connecting holes are arranged perpendicular to each other, so that the microbubble generator 100 can be fixed from multiple directions to ensure the connection reliability between the microbubble generator 100 and the detergent box 300.

[0078] In some embodiments, Figure 7 and Fig. 9 As shown, at least one fixing ear 191 is a first fixing ear 1911, and the first fixing ear 1911 extends in the front-to-back direction, that is, the first fixing ear 1911 extends toward one side of the detergent box 300, wherein a first connecting hole 1915 is provided at the front end of the first fixing ear 1911, and the first fixing ear 1911 is connected to the detergent box 300 via a first fastener penetrating through the first connecting hole 1915.

[0079] In some examples, at least one fixing ear 191 is a second fixing ear 1912, and the second fixing ear 1912 extends in the front-to-back direction, wherein a second connecting hole 1916 is provided at the front end of the second fixing ear 1912, and the second fixing ear 1912 is connected to the detergent box 300 via a second fastener passing through the second connecting hole 1916.

[0080] In some specific examples, the extension direction of the center line of the first connection hole 1915 is different from the extension direction of the center line of the second connection hole 1916. In this embodiment, the center line of the first connection hole 1915 extends in the up-down direction, and the center line of the second connection hole 1916 extends in the left-right direction, thereby fixing the micro-bubble generator 100 from the up-down direction and the left-right direction by two fasteners, further ensuring the connection reliability between the micro-bubble generator 100 and the detergent box 300.

[0081] In a further embodiment, at least one fixing ear 191 is a third fixing ear 1913, and the third fixing ear 1913 has a width direction (eg, Figure 7 and Fig. 9 The connecting portion 1914 is provided with a third connecting hole 1917 whose center line extends in the front-to-back direction, and the third fixing ear 1913 is connected to the detergent box 300 through a third fastener penetrating the third connecting hole 1917. Thus, the microbubble generator 100 is fixed from the up-down direction, the left-right direction, and the front-to-back direction by three fasteners, further ensuring the connection reliability between the microbubble generator 100 and the detergent box 300.

[0082] According to one embodiment of the present invention, the microbubble generator 100 has an air dissolving chamber 10 and a water inlet 101 and a water outlet 102 connected to the air dissolving chamber 10. The inlet 11 of the air dissolving chamber 10 forms the water inlet 101 of the microbubble generator 100, or the inlet 11 is connected to the water inlet 101, and the outlet 12 of the air dissolving chamber 10 is connected to the water outlet 102 of the microbubble generator 100. The microbubble generator 100 also has an auxiliary port 18, and the water outlet 102 or the auxiliary port 18 is connected to the water inlet hole through a microbubble pipe 52.

[0083] In some optional embodiments, such as Figure 7 , Figure 9-10 As shown, the auxiliary port 18 is located above the outlet 12 of the air dissolving chamber 10 , and the water outlet 102 of the microbubble generator 100 is connected to the water inlet hole through the microbubble connecting pipe 52 , so that the microbubble water produced by the microbubble generator 100 is passed into the water inlet manifold 51 .

[0084] like Figure 7 As shown, in this embodiment, a control valve 4 is provided at the auxiliary port 18 , and the control valve 4 is used to control the on-off of the auxiliary port 18 .

[0085] The tap water enters the air dissolving chamber 10 through the water inlet 101, and fully stimulates and dissolves the internal air in the air dissolving chamber 10 to form an air solution. When the high-concentration air solution passes through the water outlet 102, microbubble water is formed. The microbubble water flows into the water inlet manifold 51 at the bottom of the detergent box 300 through the microbubble connecting pipe 52.

[0086] When the tap water stops flowing in, there is some residual water in the air dissolving chamber 10. To ensure that there is sufficient air for dissolution in the next use of the cycle, the top control valve 4 is controlled to open, and the auxiliary port 18 after opening is connected to the atmosphere, thereby achieving the purpose of replenishing air into the air dissolving chamber 10, which is convenient for the next use or for recycling. The residual water in the air dissolving chamber 10 flows out of the microbubble generator 100 through the microbubble pipe 52 under the action of its own weight, thereby emptying the residual water.

[0087] like Figure 9-10 As shown, in this embodiment, the auxiliary port 18 is connected to the gas delivery component 6, and the gas delivery component 6 is used to ventilate the gas dissolving chamber 10.

[0088] Among them, the gas delivery component 6 is installed on the side of the microbubble generator 100, and the gas delivery component 6 is connected to the auxiliary port 18 through the connecting pipe 62, which can not only ventilate the gas dissolving chamber 10 to quickly restore the gas dissolving chamber 10 to normal pressure, but also facilitate the arrangement of the gas delivery component 6 and the microbubble generator 100.

[0089] Specifically, tap water enters the air dissolving chamber 10 through the water inlet 101, fully stimulates and dissolves the internal air in the air dissolving chamber 10, and forms an air solution. When the high-concentration air solution passes through the water outlet 102, microbubble water is formed. The microbubble water flows into the water inlet manifold 51 at the bottom of the detergent box 300 through the microbubble connecting pipe 52.

[0090] When the tap water stops flowing in, there is some residual water in the air dissolving chamber 10. To ensure that there is sufficient air for dissolution in the next use of the cycle, the air delivery component 6 is started to ventilate the air dissolving chamber 10 through the auxiliary port 18, thereby achieving the purpose of replenishing air in the air dissolving chamber 10 for the next use or for recycling. The residual water in the air dissolving chamber 10 flows out of the microbubble generator 100 through the microbubble pipe 52 under the action of the air pressure difference and its own weight, thereby emptying the residual water.

[0091] In the embodiment of the present invention, the gas delivery component 6 has a plurality of spaced-apart lugs 61, and the microbubble generator 100 has a plurality of spaced-apart fixing columns 193, wherein the fixing columns 193 have fixing holes extending along their axial direction, and the lugs 61 have matching holes, and the gas delivery component 6 is connected to the microbubble generator 100 via fasteners penetrating the matching holes and the fixing holes.

[0092] like Fig. 9 As shown, in this embodiment, two side walls of the gas delivery component 6 arranged opposite to each other are respectively provided with lugs 61, and two fixing columns 193 spaced apart in the left-right direction are provided at the rear of the microbubble generator 100, one end of each fixing column 193 is connected to the microbubble generator 100 and the other end extends backward, and the lugs 61 of the gas delivery component 6 are connected to the fixing columns 193 by fasteners, so that the gas delivery component 6 is installed at the rear of the microbubble generator 100. Optionally, the gas delivery component 6 is an air pump, which has a simple structure and is easy to implement.

[0093] Furthermore, if Fig.10 As shown, a check member 7 is provided between the auxiliary port 18 and the gas delivery component 6. For example, the check member 7 is connected to the gas delivery component 6 via a connecting pipe 62. The check member 7 is constructed to achieve one-way conduction only when air is ventilated into the gas dissolving chamber 10, that is, the gas delivery component 6 can ventilate into the gas dissolving chamber 10, while the air in the gas dissolving chamber 10 cannot flow out from the auxiliary port 18, thereby ensuring that there is enough air in the gas dissolving chamber 10.

[0094] In some embodiments, the check member 7 is disposed at the auxiliary port 18, and the check member 7 has at least two connecting ears 701. The check member 7 is connected to the microbubble generator 100 through a fastener passing through the connecting ears 701, so that the check member 7 is installed on the microbubble generator 100, with a compact structure and reliable connection.

[0095] In some embodiments, Fig.11 and Fig.12 As shown, the check member 7 includes a valve body 71 and a valve core 72. A valve cavity is defined in the valve body 71. The inlet of the valve cavity is connected to the gas delivery component 6, and the outlet of the valve cavity is connected to the auxiliary port 18. The valve core 72 is arranged in the valve cavity and moves between a first position and a second position. When the valve core 72 is in the first position, the inlet of the valve cavity is connected to the outlet of the valve cavity. When the valve core 72 is in the second position, the inlet of the valve cavity is not connected to the outlet of the valve cavity, thereby realizing one-way conduction of the auxiliary port 18.

[0096] In some specific examples, such as Fig.12 As shown, the valve body 71 includes a valve seat and a valve cover. The valve cover is sleeved on the valve seat to define a valve cavity with the valve seat. The valve core 72 is movably arranged in the valve cavity. By arranging the valve body 71 as a split structure, the installation of components such as the valve core 72 is facilitated.

[0097] In some examples, the check member 7 further includes an elastic member 73, which is connected to the valve body 71 and the valve core 72. For example, the elastic member 73 forms a spring, which is sleeved on the valve core 72. When the gas delivery component 6 ventilates the gas dissolving chamber 10, the air pressure at the inlet of the valve chamber is much greater than the air pressure at the outlet of the valve chamber, and the valve core 72 moves toward the outlet of the valve chamber and compresses the spring, thereby connecting the inlet of the valve chamber with the outlet of the valve chamber; after the gas delivery component 6 stops working, the valve core 72 is reset under the action of the spring, thereby disconnecting the inlet and outlet of the valve chamber, and preventing the gas in the gas dissolving chamber 10 from flowing back.

[0098] like Figure 8 As shown, in some other optional embodiments, the auxiliary port 18 is located below the outlet 12 of the air dissolving chamber 10 , the auxiliary port 18 is connected to the water inlet through the micro-bubble pipe 52 , and the water outlet 102 is connected to the washing inlet of the detergent box 300 .

[0099] The tap water enters the air dissolving chamber 10 through the water inlet 101, and fully stimulates and dissolves the internal air in the air dissolving chamber 10 to form an air solution. When the high-concentration air solution passes through the water outlet 102, microbubble water is formed. The microbubble water flows into the detergent box 300, impacting the detergent (or laundry liquid, washing powder, softener, etc.) in the detergent chamber. Due to the explosion of the microbubbles, the detergent will be fully dissolved and dissolved into finer particles. The microbubble water mixed with the detergent flows out through the water inlet manifold 51 at the bottom of the detergent box 300.

[0100] When the tap water stops flowing in and the microbubble water stops being generated, the bottom control valve 4 is controlled to open, and the residual water between the outlet 12 and the detergent box 300 flows back into the air dissolving chamber 10. Since the outlet 12 is located higher than the auxiliary port 18, the air in the detergent box 300 enters the air dissolving chamber 10 through the outlet 12 in the normally open state, so that the air in the air dissolving chamber 10 is replenished again; and the residual water in the air dissolving chamber 10 flows out from the auxiliary port 18 under the action of the air pressure difference and its own weight, and flows into the inner barrel of the clothing processing device or other residual water removal parts through the microbubble pipe 52, thereby emptying the residual water.

[0101] The laundry processing device according to an embodiment of the present invention comprises a water tub and a dispensing device 400 according to the above embodiment, and a water inlet manifold 51 is connected to the water tub. The laundry processing device here can be a drum washing machine, a pulsator washing machine, a washer-dryer, and the laundry processing device can also be other types of devices, which are not limited here.

[0102] The water tub is a barrel body used for processing clothes, for example, the water tub can be the inner drum of a drum washing machine, or the water tub of a pulsator washing machine, etc. The microbubble generator 100 is used to produce microbubble water, and the produced microbubble water can be used to participate in the washing process of clothes, can also be used to participate in the rinsing process of clothes, and can also participate in other processes of the clothes processing equipment that require the use of microbubble water, such as cleaning the sealing ring, cleaning dirt, etc.

[0103] The detergent box 300 has a washing inlet and a washing outlet, and the clothing processing device also includes a main water inlet pipe and a water inlet valve connected to the main water inlet pipe. The main water inlet pipe can be connected to the washing inlet and / or the water inlet 101 of the microbubble generator 100.

[0104] The specific structure and working principle of the microbubble generator 100 are described in detail below.

[0105] like Fig.13 and Fig.14 As shown, the microbubble generator 100 includes an air dissolving tank 1 and a cavitation element 2, and an air dissolving chamber 10 is defined in the air dissolving tank 1. The air dissolving tank 1 has an inlet 11 and an outlet 12 for water flow in and out. The inlet 11 of the air dissolving tank 1 forms a water inlet 101 of the microbubble generator 100, or the inlet 11 of the air dissolving tank 1 is connected to the water inlet 101, and the inlet 11 is connected to a water source (for example, a main water inlet pipe of a clothing treatment device). The water outlet 102 of the microbubble generator 100 is formed on the cavitation element 2, the cavitation element 2 is arranged outside the air dissolving tank 1 and connected to the outlet 12, or the cavitation element 2 is arranged at the outlet 12, and the cavitation element 2 converts the gas dissolved in water into microbubbles through the cavitation effect.

[0106] In some embodiments, the gas dissolving tank 1 further has an auxiliary port 18 connected to the gas dissolving chamber 10, and a check member 7 is provided at the auxiliary port 18, and the check member 7 is connected to the gas delivery component 6 through a connecting pipe 62. In other embodiments, a control valve 4 is provided at the auxiliary port 18 to control the opening and closing of the auxiliary port 18.

[0107] When the microbubble generator 100 is used, water is introduced into the air dissolving tank 1 through the inlet 11 to dissolve air, and water containing high concentration of air solute enters the cavitation element 2. The cavitation element 2 uses the cavitation effect to produce microbubbles. The water flow discharged from the cavitation element 2 contains a large number of microbubbles. After the microbubble generator 100 is used, the air delivery component 6 is started or the control valve 4 is opened to replenish air into the air dissolving chamber 10.

[0108] The prepared microbubble water can be used for many purposes such as washing. If the water contains detergents such as washing powder and laundry liquid, the bursting energy of the microbubbles can accelerate the differentiation of the detergent into smaller portions, thereby promoting the full and rapid dissolution of the detergent. Therefore, the microbubble water generated by the microbubble generator 100 can be passed into the detergent box 300 to participate in the dissolution of the detergent, or can be passed into the water bucket to participate in the dissolution of the detergent, or can be passed into other parts of the clothing treatment equipment to participate in the full dissolution of the detergent. If the stains on the clothes are relatively stubborn, it is difficult to remove the stains only by dissolving the detergent or by the friction between the clothes. The microbubble water generated by the microbubble generator 100 can participate in the washing of clothes, and the ability to remove dirt from the clothes is enhanced by the bursting energy of the microbubbles. Similarly, when the microbubble water participates in the rinsing process, the bursting energy of the microbubbles can make the detergent stained on the clothes dissolve in the water as soon as possible to avoid clothing residues. In addition, the enhanced ability of the microbubble water helps to save the water consumption of the clothing treatment equipment.

[0109] like Fig.14 As shown, in the embodiment of the present invention, the inlet 11 of the air dissolving tank 1 is located above the outlet 12, and the inlet 11 and the outlet 12 are staggered in the horizontal direction. Moreover, the microbubble generator 100 is configured such that the water outlet flow rate is less than the water inlet flow rate when dissolving air, that is, less water is discharged and more water is in per unit time. Water is injected into the air dissolving tank 1 from the inlet 11. Since the water inlet flow rate is greater than the water outlet flow rate, the water level in the air dissolving chamber 10 gradually rises after water is injected into the air dissolving tank 1 for a period of time. After the water level in the air dissolving chamber 10 rises, it will soon cover the outlet 12, so that a water seal is formed at the outlet 12. The upper cavity of the air dissolving chamber 10 gradually increases the pressure to form a high-pressure chamber, making it difficult for air in a non-dissolved state to be discharged. The solubility of air in a high-pressure state is greater than that in a low-pressure state. Therefore, the solubility of air in the air dissolving chamber 10 in water will be greatly increased, thereby completing the air dissolution. A large amount of air is dissolved in the water flowing to the cavitation element 2, so that the cavitation element 2 can produce a large number of microbubbles.

[0110] It should be emphasized here that although the outlet 12 still drains water to the cavitation element 2 after the water seal is formed at the outlet 12, the inlet 11 still continuously flows in water, so the water level in the dissolved air chamber 10 continues to rise, resulting in a gradual decrease in the air space above the water surface. When the air pressure in the dissolved air tank 1 gradually rises to a level close to the inlet water pressure, the outlet flow rate is equal to the inlet flow rate.

[0111] In addition, since the inlet 11 is located above the outlet 12, when water enters the inlet 11, the water rushes toward the water surface from above, causing the water surface to be agitated, and at the same time, some high-pressure air is brought in, which can increase the dynamic contact area between air and water. Moreover, since the inlet 11 and the outlet 12 are staggered in the horizontal direction, the flow path of the water flow in the air dissolving chamber 10 is longer, which reduces the bubbles generated by the impact of the incoming water flow and being carried away by the water flow and flowing out from the outlet 12, and increases the dissolution time and contact area of ​​the excited bubbles in the water body.

[0112] Compared with the solution in the prior art that a water flow excitation plate is arranged between the inlet 11 and the outlet 12, the embodiment of the present invention can achieve the same effect by simply staggering the inlet 11 and the outlet 12 in the horizontal direction, and using the bottom wall or the water surface of the air dissolving chamber 10 as the water flow excitation plate. In the air dissolving chamber 10 of the embodiment of the present invention, a water flow excitation plate can be arranged to further enhance the water excitation effect, or the water flow excitation plate can be omitted to improve the manufacturability of the air dissolving tank 1.

[0113] In some optional embodiments, such as Fig.14 As shown, in the horizontal direction, the baffle 3 is at least partially located between the inlet 11 and the outlet 12 , and can intercept the water flowing in from the inlet 11 in the process of flowing toward the outlet 12 .

[0114] Furthermore, if Fig.15 As shown, the baffle plate 3 is provided with a slit 31, or a through hole is provided on the baffle plate 3, or a slit 31 and a through hole are provided on the baffle plate 3, so that water dissolved with air can flow through, but the bubbles stirred up by the water splash in the air dissolving chamber 10 are blocked, preventing large bubbles from flowing to the cavitation element 2, thereby further reducing the waste of air in the air dissolving tank 1, avoiding the rapid drop of air pressure in the air dissolving chamber 10 to affect the air dissolution, and large bubbles will affect the cavitation effect after flowing into the cavitation element 2. In addition, the setting of the baffle plate 3 can form more water splashes when the incident water flow hits the baffle plate 3, and the baffle plate 3 can also serve as a reinforcement structure to enhance the pressure bearing capacity of the air dissolving tank 1.

[0115] The baffle 3 mentioned here is at least partially located between the inlet 11 and the outlet 12 in the horizontal direction, which means that the baffle 3 can be as follows Fig.14 The baffle 3 is shown as being completely located between the inlet 11 and the outlet 12, and the baffle 3 may also be only partially located between the inlet 11 and the outlet 12. For example, the baffle 3 may be formed as an arc plate or a spherical plate, and the baffle 3 covers the outlet 12, in which case the baffle 3 is only partially located between the inlet 11 and the outlet 12.

[0116] In some specific embodiments, the baffles 3 are all located between the inlet 11 and the outlet 12 in the horizontal direction, which can reduce the manufacturing difficulty.

[0117] like Fig.14 and Fig.15 As shown, in this embodiment, the baffle 3 is formed as a flat plate and is vertically connected to the bottom wall of the gas dissolving tank 1. As a result, it can not only effectively prevent the bubbles generated by the water flow from flowing out of the gas dissolving tank 1, but also facilitate production and manufacturing. Whether the straight baffle 3 is formed integrally on the gas dissolving tank 1 or fixed to the gas dissolving tank 1 by plugging or welding, it is much easier than a curved plate. Of course, this does not exclude that in other embodiments of the present invention, the baffle 3 is formed as an inclined plate, a double-layer hollow plate, or is formed as the above-mentioned curved plate, spherical plate, etc.

[0118] Specifically, Fig.15 As shown, the gap 31 on the baffle 3 is formed into a vertical strip shape in the up and down direction, which can also greatly improve the manufacturability of the microbubble generator 100. Fig.15 There is only one middle slit 31 . In other embodiments, the baffle plate 3 can be formed as a grille plate with multiple slits 31 .

[0119] In other embodiments, the baffle plate 3 is a porous plate 29 having a plurality of through holes, or the baffle plate 3 is provided with both slits 31 and through holes.

[0120] In some specific embodiments, when the baffle plate 3 is provided with a slit 31, the width of the slit 31 is less than or equal to 50 mm. It is understandable that the width of the slit 31 on the baffle plate 3 needs to be smaller to prevent bubbles formed by water flow from passing through the slit 31. Preferably, the width of the slit 31 ranges from 1 to 10 mm. Of course, the size of the slit 31 can also be selected according to actual conditions and is not limited to the above range.

[0121] Optionally, the horizontal distance between the baffle 3 and the outlet 12 is greater than the horizontal distance between the baffle 3 and the inlet 11, that is, the baffle 3 is closer to the inlet 11 in the horizontal direction, thereby ensuring the blocking effect of the baffle 3 on the water flow to excite the water bubbles, thereby ensuring the gas dissolving effect of the gas dissolving tank 1. Preferably, the horizontal distance between the baffle 3 and the inlet 11 is less than 50 mm.

[0122] When the air in the air dissolving tank 1 gradually dissolves, the air inside the air dissolving tank 1 will gradually decrease. After each use of the microbubble generator 100, the microbubble generator 100 stops taking in water. At this time, the gas delivery component 6 can be started or the control valve 4 can be opened to quickly restore the air dissolving chamber 10 to normal pressure. In addition, since the air content is low when the air dissolving chamber 10 stops taking in water, the air pressure in the air dissolving chamber 10 is lower than the external atmospheric pressure, and the microbubble water in the cavitation element 2 and even the pipeline connected to the cavitation element 2 may be sucked back into the air dissolving chamber 10. After that, the air dissolving chamber 10 under normal pressure is restored, and the residual water inside will be discharged from the opened cavitation element 2 again. After going through this process, even if there is still some residue in the air dissolving chamber 10, the residual water will not be too much, and there is sufficient air in the air dissolving tank 1, thereby ensuring that the microbubble generator 100 can dissolve enough air when used next time.

[0123] In the above embodiment, the air dissolving tank 1 is proposed to dissolve air in water, that is, to dissolve air as a solute in water, that is, air is dispersed in water molecules in the form of ions. The air ions are dispersed in the dissolved state, and the air ions in the water molecules are relatively uniform. After that, the bubbles precipitated by the cavitation effect are mostly only nanometer-level and micrometer-level in the initial stage of formation, which are the microbubbles that our microbubble generator 100 hopes to obtain. Even after the water with microbubbles flows to the final use place, the microbubbles are dissolved with each other, and most of the obtained microbubbles can still be kept at the millimeter level or even smaller, and the effect is the best, and the explosion energy can be effectively transmitted to the millimeter-level and micrometer-level fibers and detergent particles.

[0124] Moreover, if the bubbles are forcibly injected into the water, the bubbles will burst too quickly and cannot participate in the entire washing process. The air dissolved in the water is usually not completely precipitated in the cavitation element 2. During the entire washing process, the air dissolved in the water will slowly replenish microbubbles, thereby continuously generating microbubble water, reaching the participation of microbubbles in the entire washing process, and improving the washing and rinsing capabilities of the clothing treatment equipment.

[0125] It should be noted that air is a sparingly soluble gas relative to water. The percentage of the amount of air dissolved in water to the amount of air introduced is called the gas dissolving efficiency, which is related to the temperature, the gas dissolving pressure and the dynamic contact area between the gas and liquid phases. The method of changing the water temperature or the air temperature is difficult to implement. A common method of improving the gas dissolving efficiency is to use a booster pump to increase the pressure in the gas dissolving chamber 10, but various valves must be configured, so the cost of configuring a booster pump is too high.

[0126] Another solution in the prior art is to set a double inlet in the air dissolving device, one inlet is used to take in water, and the other inlet is used to take in air while taking in water. It is necessary to use a booster pump to pressurize the air into the water in order to inject air into the flowing water. In this solution, because the air inlet is located below the cavitation element 2, the incoming bubbles will quickly flow toward the cavitation element 2 and be squeezed out. There is no space in the air dissolving tank 1 for the bubbles to slowly dissolve, and the air dissolving effect is not ideal. The method of injecting air into the water by boosting is equivalent to directly pressing large bubbles into the water. Such large bubbles stay in the water for a short time and have insufficient dissolution time. Even when passing through the cavitation element 2, the large bubbles are squeezed into more small bubbles by the cavitation element 2, but the size of the small bubbles is at the millimeter level or even larger, and they will quickly break and release.

[0127] The micro-bubble generator 100 of the present application utilizes the flow velocity difference of the water flow in and out of the gas dissolving chamber 10, and the height difference between the inlet 11 and the outlet 12, to form a water seal at the outlet 12, so that the gas dissolving chamber 10 is gradually pressurized to form a high-pressure chamber, thereby increasing the amount of dissolved gas. The arrangement of the gas delivery component 6 or the control valve 4 enables the residual water in the gas dissolving chamber 10 to be discharged and the air to be replenished after each use of the micro-bubble generator 100.

[0128] The cavitation element 2 of the microbubble generator 100 of the present application is connected to the detergent box 300, and the microbubble water is guided to the detergent box 300 and then flows to the water tub, which can reduce the number of connecting pipes on the water tub. On the one hand, it is easy to seal, and on the other hand, the highly integrated structure can reduce the volume. There is no need to install multiple valves, and the generation of microbubbles is achieved with a relatively simple structure, which is conducive to improving the compactness, integration and stability of the structure. The above-mentioned microbubble generator 100 does not need to install multiple valves, has low cost and good microbubble manufacturing effect. The washing water contains a large number of microbubbles, which reduces the amount of detergent used, saves water and electricity resources, and reduces the detergent residue on the clothes.

[0129] In the embodiment of the present invention, the gas dissolving tank 1 can be formed into any shape, and no specific limitation is made here. However, the gas dissolving tank 1 needs to ensure that other positions of the gas dissolving tank 1 except the outlet 12 have good sealing performance during gas dissolving operation.

[0130] Specifically, the cross-sectional area of ​​the air dissolving chamber 10 perpendicular to the inlet 11 is relatively small. It is understandable that when the water flows into the air dissolving chamber 10, the incident water flow will hit the inner wall of the air dissolving chamber 10 and the liquid surface in the air dissolving chamber 10. This phenomenon will produce more water splashes, and the generation of water splashes is conducive to bringing the water body into the high-pressure air above, increasing the speed of air dissolving in the water body. The cross-sectional area of ​​the air dissolving chamber 10 perpendicular to the inlet 11 is relatively small, which is conducive to the water splashes generated during the incident water flow of the inlet 11 hitting the water surface, and the inner wall of the air dissolving chamber 10 produces a relatively strong physical effect, so that the water body can dissolve air faster.

[0131] like Figure 14-15 As shown, the inlet 11 is located at the top of the gas dissolving tank 1 or close to the top; the outlet 12 is located at the bottom of the gas dissolving tank 1 or close to the bottom.

[0132] In some optional embodiments, such as Figure 14-15 As shown, the incident direction of the inlet 11 is vertically downward, and the incoming water flow is injected into the air dissolving chamber 10 along the vertical direction, which not only increases the generation of water splashes, thereby accelerating the air dissolution rate, but also facilitates the manufacturability of mass production of the air dissolving tank 1. Of course, in other embodiments of the present invention, the incident direction of the inlet 11 can also be inclined, that is, the incident direction of the water flow can be at a certain angle to the vertical direction, so that the impact area of ​​the incident water flow is very large.

[0133] In some embodiments, in the horizontal direction, such as Fig.14 As shown, the inlet 11 and the outlet 12 are located at the two ends of the air dissolving tank 1 , thereby further lengthening the flow path of the water flow inside the air dissolving tank 1 and further reducing the bubbles produced by the water flow flowing out through the outlet 12 .

[0134] The cross section of the gas dissolving chamber 10 in the horizontal direction is a square, and the inlet 11 and the outlet 12 are arranged at the farthest distance of the straight line distance between the two ends of the square. For example, the cross section of the gas dissolving chamber 10 in the horizontal direction is a rectangle, and the inlet 11 and the outlet 12 are located at the two ends of the long side of the rectangle. This gas dissolving tank 1 is easy to process and easy to lay out during assembly. Of course, in other embodiments of the present invention, the cross-sectional shape of the gas dissolving chamber 10 can be formed into any shape and is not limited to a rectangle, a rhombus or other irregular squares.

[0135] Advantageously, if Fig.14 As shown, the inlet 11 is located at the top of the air dissolving chamber 10, which can ensure that the incident water flow can stir up more water splashes and improve the air dissolving effect. Optionally, the outlet 12 is located at the bottom of the air dissolving chamber 10, so that the outlet 12 can form a water seal as soon as possible.

[0136] In some embodiments, the distance between the inlet 11 and at least one side wall of the air dissolving chamber 10 is less than 50 mm. That is, when the inlet 11 is in working state, the projection of the inlet 11 to the water surface in the vertical direction is less than 50 mm from the inner wall surface of at least one air dissolving chamber 10. The water flow at the inlet 11 is more likely to hit the side wall of the air dissolving tank 1 to produce water splashes, thereby improving the air dissolving effect of the air dissolving tank 1. Optionally, the distance between the inlet 11 and at least one side wall of the air dissolving chamber 10 is between 1-20 mm. Of course, in other embodiments of the present invention, the inner wall of the air dissolving chamber 10 can be provided with structures such as inner convex ribs to make it easier to stir up water splashes.

[0137] In the embodiment of the present invention, the gas dissolving tank 1 is provided with two gas dissolving half shells 13 which are interlocked with each other, the inlet 11 is provided on one of the gas dissolving half shells 13, and the outlet 12 is provided on the other gas dissolving half shell 13. The inlet 11 and the outlet 12 are provided on the two gas dissolving half shells 13 respectively, which is easy to form, and the strength of each gas dissolving half shell 13 is not too low. The gas dissolving tank 1 has strong manufacturability, is convenient for mass production, and has low processing cost.

[0138] In some specific embodiments, the two gas-dissolving half shells 13 are connected by welding or gluing to ensure the sealing performance. In other specific embodiments, the gas-dissolving tank 1 is a plastic part, for example, each gas-dissolving half shell 13 is an integral injection-molded part.

[0139] The upper part of the gas dissolving tank 1 is provided with a water inlet pipe 14 connected to the top of the gas dissolving chamber 10, and the lower part of the gas dissolving tank 1 is provided with a water outlet pipe 15 connected to the bottom of the gas dissolving chamber 10. The water inlet pipe 14 and the water outlet pipe 15 are arranged horizontally, which is convenient for assembly. For example, when the micro-bubble generator 100 is used in an integrated manner with the detergent box 300, the gas dissolving tank 1 is installed behind the detergent box 300, and the water inlet pipe 14 and the water outlet pipe 15 are arranged horizontally to make assembly easier.

[0140] like Figure 14-15 As shown, in this embodiment, two air-dissolving half shells 13 are arranged up and down, the water inlet pipe 14 is integrally formed on the upper air-dissolving half shell 13, and the water outlet pipe 15 is integrally formed on the lower air-dissolving half shell 13, so that the processing convenience and sealing can be guaranteed.

[0141] Specifically, the two gas-dissolving half shells 13 are in contact with each other at the joint through the step surface 16, which not only increases the contact area of ​​the two gas-dissolving half shells 13 at the joint, but also improves the contact strength. In addition, the step surface 16 is in contact with each other, so that at least part of the contact surface of the two gas-dissolving half shells 13 is perpendicular or nearly perpendicular to the pressure of the inner wall of the gas-dissolving chamber 10. This makes the two gas-dissolving half shells 13 more and more tightly pressed at the joint due to the internal high pressure, avoiding the joint from cracking and leaking due to the internal high pressure.

[0142] Furthermore, the outer surface of the gas dissolving tank 1 is provided with reinforcing ribs 17 arranged in a staggered manner in both horizontal and vertical directions, so as to increase the strength of the gas dissolving tank 1 and prevent deformation and gas leakage due to the internal high pressure.

[0143] In the embodiment of the present invention, the cavitation element 2 may adopt the structure of a cavitation device that is already known in the prior art, such as an ultrasonic generator, etc. For example, at least one Venturi channel 25 is formed in the cavitation element 2 .

[0144] In some optional embodiments, such as Fig.17As shown, the cavitation element 2 is a perforated plate 29 provided with a plurality of micropores. Thus, the air dissolved in the water flow passing through the cavitation element 2 can be precipitated relatively simply and made into bubbles. Specifically, the radius of the micropores on the perforated plate 29 is 0.01 mm-10 mm. Experiments have shown that the perforated plate 29 with the above parameters has a better cavitation effect and can generate more bubbles. Of course, the specific parameters of the perforated plate 29 can be adjusted by the staff according to the actual working conditions and are not limited to the above ranges.

[0145] In some other optional embodiments, Fig.16 As shown, the cavitation element 2 includes a venturi tube 28, and a venturi channel 25 is formed in the venturi tube 28. As a result, the air dissolved in the water flow passing through the cavitation element 2 can be precipitated relatively simply and made into bubbles. By using the venturi tube 28 as the cavitation element 2, there is no need to design extra water pumps, heating devices or control valves, etc., which greatly simplifies the structure of the cavitation element 2 and reduces the production cost. In addition, the venturi tube 28 has no additional requirements for the water inlet method, so that the cavitation element 2 can easily generate a large number of bubbles.

[0146] In some specific embodiments, Figure 18-Figure 20 As shown, the cavitation member 2 is formed into a deformed structure having a plurality of venturi channels 25. Fig.18 As shown, the cavitation member 2 is generally a column, and a plurality of venturi channels 25 are arranged in the cavitation member 2. Such a structure, on the one hand, lengthens the path length of the venturi channel 25, which is conducive to the time sufficiency of the venturi effect, and on the other hand, facilitates processing and manufacturing, and is convenient for assembly, especially when connected to the nozzle.

[0147] Specifically, if Fig. 20 As shown, the Venturi channel 25 in the cavitation element 2 includes: a tapered section 251, a throat 252 and a gradually expanding section 253 in the direction of water flow. The diameter of the tapered section 251 gradually decreases in the direction toward the throat 252, and the diameter of the gradually expanding section 253 gradually increases in the direction away from the throat 252. The throat 252 has the smallest flow area in the Venturi channel 25.

[0148] Specifically, the cavitation member 2 is formed in a cylindrical shape, and a diverter groove 261 and a converging groove 262 are respectively formed at opposite ends of the cavitation member 2 , and the venturi channel 25 is formed between the bottom wall of the diverter groove 261 and the bottom wall of the converging groove 262 .

[0149] The cavitation element 2 is generally connected to the clothing treatment device through a pipeline, so the inner diameter of the outlet of the cavitation element 2 can be selected between 5-15 mm. Further, the inner diameter of the outlet of the cavitation element 2 can be controlled between 7-10 mm. Fig. 20 In the example, the diameter of the conduit groove 262 can be selected between 5-15 mm, and further can be selected between 7-10 mm.

[0150] Optionally, the number of the Venturi channels 25 is 1-30, and further optionally, the number of the Venturi channels 25 is 4-6. As a key component, the cavitation element 2 needs to be responsible for processing the water flow entering the clothing treatment device, and the water entering the clothing treatment device generally uses domestic tap water. The flow rate of domestic tap water is generally 5-12L / min, and the water pressure is generally 0.02-1Mpa. More commonly, the flow rate is generally 8-10L / min, and the water pressure is generally 0.15-0.3Mpa. Therefore, the number of the Venturi channels 25 in the cavitation element 2 can be selected to be 4-6.

[0151] The relevant principles of cavitation are:

[0152] The average velocity, average pressure and cross-sectional area at the inlet of the tapered section 251 are V1, P1 and S1 respectively, and the average velocity, average pressure and cross-sectional area at the throat 252 are V2, P2 and S2 respectively. The density of water is ρ. In the working state, the clothing processing equipment uses tap water as the working medium, satisfying the relationship: S1*V1=S2*V2.

[0153] Using Bernoulli's principle and the continuity equation, we can obtain the relationship: V12 / 2+P1 / ρ=V / 2+P2 / ρ.

[0154] In this process, by controlling the changes of S1 and S2, the flow velocity at the throat 252 in the Venturi channel 25 increases and the pressure at the throat 252 decreases, so that the air dissolved in the water is released in the form of microbubbles.

[0155] As a diffusion section, the ideal diffusion of the gradually expanding section 253 should make the fluid gradually decelerate, so the gradually expanding section 253 needs a certain length. Optionally, the length of the gradually expanding section 253 is greater than the length of the gradually contracting section 251. Further optionally, the length ratio of the gradually contracting section 251 to the gradually expanding section 253 is 1:2-1:4. Further optionally, the length ratio of the gradually contracting section 251 to the gradually expanding section 253 is 1:3-1:4.

[0156] Since the Venturi channel 25 needs to be distributed in the cavitation member 2 with a relatively limited cross-sectional area, the diameter of the Venturi channel 25 is limited at various locations. Optionally, the diameter of the throat is 0.7-2.0 mm, and further optionally, the diameter of the throat is 0.9-1.1 mm. In addition, the end diameters of the tapered section 251 and the expanding section 253 are both larger than the diameter of the throat 252, at least 0.1 mm larger. Optionally, the end diameter of the tapered section 251 away from the throat 252 ranges from 1 to 4 mm, and the end diameter of the expanding section 253 away from the throat 252 ranges from 1 to 4 mm. Further optionally, the ratio of the diameter of the throat 252 to the end diameter of the tapered section 251 is approximately 1:1.3-2. The ratio of the diameter of the throat 252 to the end diameter of the expanding section 253 is approximately 1:1.3-2.

[0157] Furthermore, if Figure 18-Figure 20 As shown, for easy installation, a threaded section 231 is formed at one end of the cavitation member 2, and the threaded section 231 can be either an internal thread or an external thread. Fig.17 and Fig.19 In the example, the threaded section 231 of the cavitation element 2 at one end connected to the dissolved air tank 1 is an external thread, which is screwed onto the dissolved air tank 1 through the thread, and the connection is very convenient.

[0158] In other specific embodiments, Fig.21 As shown, the cavitation element 2 includes: a cavitation shell 23 and a cavitation ball 24. A water passage chamber 20 is provided in the cavitation shell 23, and the cavitation shell 23 has a cavitation inlet 21 and a cavitation outlet 22 for water flow in and out, and the cavitation inlet 21 is connected to the outlet 12 of the gas dissolving tank 1. The cavitation ball 24 is movably arranged in the water passage chamber 20, and the water flowing in from the cavitation inlet 21 can push the cavitation ball 24 to block at the cavitation outlet 22, and when the cavitation ball 24 is blocked at the cavitation outlet 22, a venturi channel 25 is formed between the cavitation ball 24 and the inner wall of the water passage chamber 20.

[0159] When the cavitation ball 24 blocks the cavitation outlet 22, a venturi channel 25 communicating with the cavitation outlet 22 is provided between the cavitation ball 24 and the inner wall of the water passage chamber 20. It is shown here that the cavitation ball 24 does not completely block the cavitation outlet 22, but leaves the venturi channel 25 so that the water flow containing dissolved air gradually flows out from the cavitation outlet 22.

[0160] By arranging a movable cavitation ball 24 in the water passage chamber 20 in front of the cavitation outlet 22, when the water flow containing dissolved air is continuously introduced into the cavitation inlet 21, the continuously introduced water flow flows along the inner wall of the water passage chamber 20, and after encountering the cavitation ball 24, the cavitation ball 24 is pushed to move toward the cavitation outlet 22, so that the cavitation ball 24 moves to the front of the cavitation outlet 22 and gradually stops on the cavitation outlet 22, forming a Venturi channel 25.

[0161] When the water flow containing dissolved air solutes passes through the Venturi channel 25, the flow area will first shrink and then expand. When the flow area shrinks and the flow velocity of the water flow with gas solutes increases, the pressure decreases. When the flow area increases and the flow velocity of the water flow with gas solutes decreases, the pressure increases. A Venturi effect will occur in the Venturi channel 25, and air will precipitate from the solute state to form microbubbles. In addition, the water flow keeps the cavitation ball 24 against the cavitation outlet 22, and also makes the water flow containing dissolved air solutes flow out of the Venturi channel 25 faster.

[0162] In this process, the water flow rate continuously introduced is greater than the water flow rate discharged, and the water chamber 20 acts as an air-locked chamber. When the cavitation outlet 22 thereof is stopped by the cavitation ball 24, the internal pressure thereof will increase, thereby strengthening the cavitation effect.

[0163] The use of this cavitation element 2 is not only low in cost and processing difficulty, but also has advantages that other cavitation structures do not have. The cavitation ball 24 is a movable sphere. When the microbubble generator 100 stops working, the water flow rate decreases, and the cavitation ball 24 without water flow will leave the cavitation outlet 22, so that the remaining water in the microbubble generator 100 can be removed as soon as possible. This is convenient for pre-storing air in the air dissolving tank 1, and on the other hand, it is prevented from accumulating water and breeding too many bacteria. In addition, this cavitation element 2 is also easy to clean.
