Description

Technical Field

[0001] The present application relates to the technical field of clothing treatment equipment, and in particular to a dosing device for clothing treatment equipment and a clothing treatment equipment. Background Art

[0002] In the technical field of washing machines, the traditional atomized washing technology atomizes the detergent through high-pressure water flow and sprays it onto the surface of the clothes to enhance the washing effect and reduce water consumption. However, this technology faces a significant technical problem in practical applications: due to the huge pressure generated by the water flow during high-pressure atomization, the existing washing machine designs often need to be provided with special pressure relief ports to balance the system pressure and prevent equipment damage (such as causing the water box to burst, leak, or performance degradation, etc.). However, this design compromise directly results in part of the atomized laundry detergent flowing back to the space between the detergent box and the inner and outer drums under high pressure through the pressure relief port, rather than directly acting on the clothes. This phenomenon not only weakens the penetration and peeling ability of the atomized bubbles on the clothes stains, greatly reducing the advantages of the atomized washing technology, but also causes waste of detergent, reduces the utilization rate of the detergent, increases the user's washing cost. Summary of the Utility Model

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. For this purpose, an object of the present application is to provide a dosing device for clothing treatment equipment, which is controlled by a first valve and a second valve respectively. The first valve can limit the water flow rate to be relatively small to reduce the fluid pressure in the first water inlet flow path, protect the equipment from high-pressure damage, and can cancel the additional pressure relief port, so that all the washing media can directly act on the clothes, thereby improving the atomized bubble effect of the detergent, increasing the utilization rate of the detergent, enhancing the washing effect and efficiency of the clothes, and saving the washing cost.

[0004] The present application also provides a clothing treatment equipment having the above-mentioned dosing device for clothing treatment equipment.

[0005] According to the dosing device for clothing treatment equipment of the first aspect embodiment of the present application, the dosing device for clothing treatment equipment includes: a first valve and a second valve. The first valve is adapted to control the water flow rate flowing through the first water inlet flow path, wherein the first water inlet flow path is adapted to dissolve additives and input them into the clothing treatment cavity; the second valve is adapted to control the water flow rate flowing through the second water inlet flow path, wherein the second water inlet flow path is isolated from the first water inlet flow path, and the flow rate of the second valve is greater than that of the first valve.

[0006] The dosing device for a laundry treatment device according to the present application can make the water flow rates of the water path for dissolving additives and the water path for washing water, etc., different by setting a first valve and a second valve to respectively control the water flow rates flowing through the first water inlet path and the second water inlet path. The flow rate of the first valve is relatively small to reduce the fluid pressure in the water path where the additive is dissolved, avoiding damage to dosing components, etc. caused by excessive fluid pressure. Thus, an additional pressure relief port can be eliminated, preventing the washing medium from flowing back from the pressure relief port to the space between the dosing component and the inner and outer drums of the laundry treatment device. It can ensure that the washing medium directly acts on the laundry completely, thereby improving the atomization bubble effect of the detergent, increasing the utilization rate of the detergent, enhancing the laundry washing effect and efficiency, and saving the washing cost. At the same time, the second valve can ensure an appropriate washing water flow rate to meet the cleaning requirements of the laundry and the laundry treatment device.

[0007] According to some embodiments of the present application, the flow rate of the first valve is less than or equal to 4 L / min.

[0008] Further, the first water inlet path is a continuous closed water path with one end connected to an external water source and the other end connected to the laundry treatment chamber.

[0009] In some embodiments, the dosing device for the laundry treatment device further includes: a dosing unit adapted to dose an additive into the first water inlet path.

[0010] According to some embodiments of the present application, the dosing device for the laundry treatment device further includes: a water box, a first pipe, and a second pipe. The water box has a first water inlet chamber, and a first inlet and a first outlet communicating with the first water inlet chamber. The dosing unit is adapted to dose an additive towards the first water inlet chamber; one end of the first pipe is connected to the first inlet, and the first valve is provided at the other end; one end of the second pipe is connected to the first outlet, and the other end is connected to the laundry treatment chamber; wherein the first pipe, the first water inlet chamber, and the second pipe define the first water inlet path.

[0011] Further, the dosing device for the laundry treatment device further includes: a spray head, which is connected to the second pipe and an atomization outlet facing the laundry treatment chamber is formed on the spray head.

[0012] In some embodiments, a second water inlet chamber isolated from the first water inlet chamber is formed on the water box, and a second inlet and a second outlet communicating with the second water inlet chamber are provided. It further includes: a third pipe and a fourth pipe. One end of the third pipe is connected to the second inlet, and the second valve is provided at the other end; one end of the fourth pipe is connected to the second outlet, and the other end is connected to the laundry treatment chamber.

[0013] Further, the dispensing unit further includes: a dispensing box, which is received in the water box and has a dispensing cavity, and a water outlet communicating the second water inlet cavity with the dispensing cavity is formed on the water box.

[0014] In some embodiments, the second inlet and the first inlet are disposed on the same side of the water box, and the first valve and the second valve are adjacent to each other and fixedly connected.

[0015] According to the clothes treatment device of the second aspect embodiment of the present application, the clothes treatment device includes: the dispensing device for the clothes treatment device according to any one of the above embodiments.

Among them, the first pipe, the first water inlet cavity of the water box, and the second pipe define a first water inlet flow path to dissolve the additive and dispense it into the clothes treatment cavity. The first water inlet flow path is a continuous closed water path with one end communicating with an external water source and the other end communicating with the clothes treatment cavity. The first valve can control the water flow rate flowing through the first water inlet flow path to limit the fluid flow rate in the first water inlet cavity and reduce the fluid pressure, thereby avoiding damage to components such as the dispensing box and the water box caused by excessive pressure, eliminating the need for an additional pressure relief port, preventing the washing medium from flowing back from the pressure relief port to the space between the dispensing box and the inner and outer drums of the clothes treatment device, enabling the washing medium to act directly on the clothes entirely, thereby improving the atomized bubble effect of the detergent and increasing the utilization rate of the detergent.

[0035] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0036] Reference will be made below to Figures 1-5 describe a dosing device 100 for a laundry treatment device and a laundry treatment device according to an embodiment of the present application.

[0037] As Figure 1 and Figure 2 shown, a dosing device 100 for a laundry treatment device according to an embodiment of the first aspect of the present application includes: a first valve 1 and a second valve 2.

[0038] Among them, the first valve 1 is adapted to control the water flow rate flowing through the first water inlet flow path, and the first water inlet flow path is adapted to dissolve additives and input them into the laundry treatment chamber; the second valve 2 is adapted to control the water flow rate flowing through the second water inlet flow path. The second water inlet flow path is isolated from the first water inlet flow path, and the flow rate of the second valve 2 is greater than that of the first valve 1.

[0039] Specifically, the dosing device 100 for a laundry treatment device may have two water inlet flow paths, namely a first water inlet flow path and a second water inlet flow path. The first water inlet flow path is adapted to dissolve additives and introduce them into the laundry treatment chamber to clean the laundry. Among them, the additives may be liquid detergents and / or solid detergents. The liquid detergents may include detergents, fabric softeners, germicides, care agents, and other common preparations. The solid detergents may include washing powder, laundry gel, laundry beads, etc. The first valve 1 can control the water flow rate through the first water inlet flow path to precisely control the flow rate, pressure, etc. of the first water inlet flow path to meet the pressure requirements and washing requirements of the surrounding components defining the first water inlet flow path, etc.; the second water inlet flow path is arranged separately from the first water inlet flow path. The second water inlet flow path can be used to introduce washing water, etc. into the laundry treatment chamber, and the second valve 2 can control the water flow rate through the second water inlet flow path to control the dispensing speed and water consumption of the washing water, etc.

[0040] It should be noted that if the water flow pressure of the first water inlet flow path for dissolving additives is too high, it will be necessary to additionally set a pressure relief port to avoid damage to components and systems due to high pressure. In this application, the flow rate of the second valve 2 is greater than that of the first valve 1, and the flow rate of the first valve 1 is small to fully limit the flow of the first water inlet flow path, thereby reducing the pressure of the fluid on the surrounding components of the first water inlet flow path, etc., so as to avoid damage to the equipment due to the high pressure of the fluid. Furthermore, it is possible to cancel the additional setting of the pressure relief port. In this way, it is possible to prevent the additives and water flow from flowing back from the pressure relief port to the space between the dosing component and the inner and outer drums of the laundry treatment device, and it is possible to ensure that the washing medium can directly act on the laundry entirely, thereby improving the atomization bubble effect of the additives and increasing the utilization rate of the detergent. At the same time, since sufficient water volume and appropriate flow rate are required for laundry washing, etc. to ensure the cleaning effect, therefore, compared with the first valve 1, the flow rate of the second valve 2 is greater. In this way, it helps to efficiently clean the laundry and quickly flush away the foam and additive residues on the inner wall of the laundry treatment chamber, etc., to improve the utilization rate of the additives, effectively enhance the cleaning ability of the laundry treatment device for the laundry, and maintain the hygiene and clean appearance of the device.

[0041] The dosing device 100 for a laundry treatment device according to the present application can differentiate the water flow rate of the waterway for dissolving additives and the water flow rate of washing water, etc. by setting the first valve 1 and the second valve 2 to control the water flow rate flowing through the first water inlet flow path and the second water inlet flow path respectively. The flow rate of the first valve 1 is relatively small to reduce the fluid pressure of the waterway where the additive is dissolved, avoid damage to dosing components, etc. caused by excessive fluid pressure, and thus an additional pressure relief port can be eliminated. It can prevent the washing medium from flowing back from the pressure relief port to the space between the dosing component and the inner and outer drums of the laundry treatment device, enable the washing medium to directly act on the clothes entirely, thereby improving the atomized bubble effect of the detergent, increasing the utilization rate of the detergent, enhancing the laundry washing effect and efficiency, and saving the washing cost. At the same time, the second valve 2 can ensure an appropriate washing water flow rate to meet the cleaning requirements of the clothes and the laundry treatment device.

[0042] As Figure 1 and Figure 2 shown, according to some embodiments of the present application, the flow rate of the first valve 1 is less than or equal to 4 L / min.

[0043] Specifically, when the flow rate of the first valve 1 exceeds 4 L / min, for example, the flow rate of the first valve 1 is 5 L / min or 6 L / min, etc., it will cause the pressure generated by the fluid in the first water inlet flow path on the surrounding components to be too large, easily leading to component rupture, leakage, or even serious damage, reducing the working reliability and cleaning ability of the laundry treatment device. The flow rate of the first valve 1 of the present application is set within the range of less than or equal to 4 L / min, making the pressure of the washing medium relatively small, which can further ensure that the fluid pressure is within a safe range, thus effectively avoiding the risk of component damage due to high-pressure impact. In this way, after eliminating the setting of an additional pressure relief port, the components are within a safe pressure range during operation, which can effectively protect the integrity of dosing components, etc. and extend their service life.

[0044] It should be noted that setting the flow rate of the first valve 1 to be less than or equal to 4 L / min also takes into account the adaptability and flexibility of the device, enabling the dosing device 100 for a laundry treatment device to be applicable to laundry treatment devices of different models and specifications and meet different washing requirements.

[0045] In addition, in some specific embodiments of the present application, the flow rate of the second valve 2 is set to 8 L / min to further ensure the washing water flow rate and enhance the water flow impact force, which can further improve the cleaning efficiency and effect. At the same time, setting the flow rate of the second valve 2 to 8 L / min is also beneficial to improving the adaptability of the second valve 2 to an external water source with a conventional flow rate.

[0046] As Figures 1-3As shown, according to some embodiments of the present application, the first water inlet flow path is a continuous closed water path with one end communicating with an external water source and the other end communicating with the laundry treatment chamber.

[0047] Specifically, the first water inlet flow path is a continuous and closed water path starting from the external water source and reaching the laundry treatment chamber, so that the first water inlet flow path has good sealing performance, optimizes the anti-leakage performance of the first water inlet flow path, can avoid the leakage of additives and water flow, and can further improve the washing effect and the utilization rate of additives. It can be understood that the part of the first water inlet flow path where additives are put in is also a closed structure. For example, the addition of additives can be realized by automatically pumping from the dosing component into the first water inlet flow path, and the first valve 1 controls the small water flow rate of the first water inlet flow path, which can reduce the fluid pressure in the continuous closed water path and ensure that the fluid pressure is within the safe pressure range of the components around the first water inlet flow path, so as to protect the components around the first water inlet flow path from high-pressure damage.

[0048] It should be noted that the second water inlet flow path is different from the first water inlet flow path. The second water inlet flow path may not be a closed water path, so as not to damage the components due to excessive flow and inability to release pressure under a closed structure. Moreover, even if the second water inlet flow path is constructed as a closed water path, since the water path for dissolving additives and putting them into the laundry treatment chamber is the first water inlet flow path, when part of the cleaning water flows to the space between the component and the inner and outer barrels of the laundry treatment device due to pressure in the second water inlet flow path, it will not have a negative impact on the laundry cleaning and the operation of the laundry treatment device. Therefore, there is no need to focus on the flow limiting intensity of the second water inlet flow path.

[0049] As Figures 1-3 shown, according to some embodiments of the present application, the dosing device 100 for a laundry treatment device further includes: a dosing unit, and the dosing unit is adapted to dose additives into the first water inlet flow path.

[0050] Specifically, the dosing unit is used to dose additives into the first water inlet flow path. Exemplarily, the dosing unit can accurately control the dosing amount of additives according to a preset washing program or a user instruction, and accurately dose the additives into the first water inlet flow path. At the same time, since the first valve 1 limits the flow rate of the first water inlet flow path, it can ensure that the water flow has an appropriate pressure, so as to have good ability to dissolve additives while not causing high-pressure damage to the device, thus taking into account both the washing effect and the device safety.

[0051] In addition, in some specific embodiments of the present application, the dosing unit should be constructed as a structure that is easy to disassemble and clean, so as to maintain its good working state and dosing accuracy during long-term use.

[0052] As Figures 1-3As shown, according to some embodiments of the present application, the dosing device 100 for a laundry treatment device further includes: a water box 3, a first pipe 4, and a second pipe 5.

[0053] Wherein, the water box 3 has a first water inlet chamber 3a, a first inlet 3c communicating with the first water inlet chamber 3a, and a first outlet. The dosing unit is adapted to dose an additive towards the first water inlet chamber 3a; one end of the first pipe 4 is connected to the first inlet 3c, and a first valve 1 is provided at the other end; one end of the second pipe 5 is connected to the first outlet, and the other end is in communication with the laundry treatment chamber; the first pipe 4, the first water inlet chamber 3a, and the second pipe 5 define a first water inlet flow path.

[0054] Specifically, the first water inlet chamber 3a of the water box 3 can be used for the injection, storage, and discharge of fluid. The first water inlet chamber 3a communicates with both the first inlet 3c and the first outlet. An external water source can enter the first water inlet chamber 3a from the first inlet 3c, and the additive can be dosed into the first water inlet chamber 3a and dissolved in the water flow. After the washing medium formed by the additive and the water flow flows through the first water inlet chamber 3a, it can flow out from the first outlet. Among them, a first pipe 4 is connected to the first inlet 3c. The first pipe 4 has a certain length, and a first valve 1 is provided at the end of the first pipe 4 away from the first inlet 3c. The first valve 1 is located upstream of the first inlet 3c, so that the first valve 1 can accurately control the water flow rate flowing into the first water inlet chamber 3a through the first pipe 4, limit the fluid pressure of the first water inlet flow path, and protect components such as the water box from high-pressure damage. A second pipe 5 is connected to the first outlet. The second pipe 5 has a certain length, and the end of the second pipe 5 away from the first outlet is in communication with the laundry treatment chamber. The second pipe 5 can accurately introduce the washing medium flowing out from the first outlet into the laundry treatment chamber to clean the clothes.

[0055] As Figures 1-5 shown, according to some embodiments of the present application, the dosing device 100 for a laundry treatment device further includes: a spray head, which is in communication with the second pipe 5 and has an atomizing outlet facing the laundry treatment chamber formed thereon.

[0056] Specifically, the spray head can be in communication with the second pipe 5. After the washing medium formed by the water flow and the additive flows through the first water inlet chamber 3a, the first outlet, and the second pipe 5 in sequence, it can flow into the spray head. An atomizing outlet is formed on the spray head. The atomizing outlet can be configured as a micropore or a special spraying structure to refine the washing medium into tiny droplets and spray them out evenly. Therefore, by providing the spray head, the washing medium can be sprayed into the laundry treatment chamber in an atomized form to clean the clothes. It can be understood that by the atomized spraying method, the contact area between the washing medium and the clothes can be increased, and the additive can be more evenly distributed on the clothes, thereby improving the washing effect and cleanliness.

[0057] As Figure 3As shown, according to some embodiments of the present application, a second water inlet chamber 3b isolated from the first water inlet chamber 3a is formed on the water box 3, and a second inlet 3d and a second outlet communicating with the second water inlet chamber 3b are provided. The dosing device 100 for a laundry treating apparatus further includes: a third pipe 6 and a fourth pipe 7. One end of the third pipe 6 is connected to the second inlet 3d, and a second valve 2 is provided at the other end. One end of the fourth pipe 7 is connected to the second outlet, and the other end is communicated with the laundry treating chamber.

[0058] Specifically, the second water inlet chamber 3b is isolated from the first water inlet chamber 3a. It can be understood that a partition is provided in the water box 3 to separate the second dosing chamber from the first dosing chamber 3a, so as to ensure the isolation of the second water inlet flow path and the first water inlet flow path. Both the second inlet 3d and the second outlet are communicated with the second water inlet chamber 3b. External water source can enter the second water inlet chamber 3b from the second inlet 3d and flow into the laundry treating chamber through the second outlet for washing clothes or spraying on the door glass, etc. Among them, the third pipe 6 is connected to the second inlet 3d. The third pipe 6 has a certain length, and a second valve 2 is provided at the end of the third pipe 6 far from the second inlet 3d. The second valve 2 is located upstream of the second inlet 3d. Thus, by means of the second valve 2, the water flow rate of the second water inlet flow path can be accurately controlled to meet the washing and spraying cleaning requirements of the door glass. The fourth pipe 7 is connected to the second outlet. The fourth pipe 7 has a certain length, and the end of the fourth pipe 7 far from the second outlet is communicated with the laundry treating chamber. The fourth pipe 7 can convey the water flow flowing out from the second outlet into the laundry treating chamber.

[0059] By providing the second water inlet chamber 3b, the second inlet 3d, the second outlet and the corresponding pipe and valve configurations, the water box 3 can simultaneously process the water flows from different water inlet flow paths and perform different functions (the first water inlet flow path dissolves additives, and the second water inlet flow path doses clean water), improving the versatility of the water box 3. By accurately controlling the flow rate of the second valve 2 (such as 8 L / min), it can be ensured that sufficient water volume and appropriate flow rate are provided when needed to meet the cleaning spraying requirements of the door glass, etc., thereby improving the cleaning efficiency and effect.

[0060] As Figures 1-3 As shown, according to some embodiments of the present application, the dosing unit further includes: a dosing box. The dosing box is received in the water box 3 and the dosing box has a dosing chamber. An outlet communicating the second water inlet chamber 3b with the dosing chamber is formed on the water box 3.

[0061] Specifically, the dosing box can be received inside the water box 3. The dosing cavity of the dosing box can be used to store and release additives, ensuring that the additives are dosed into the water flow at an appropriate time. At the same time, the dosing cavity is communicated with the second water inlet cavity 3b through the water outlet of the water box 3, so that the water flow can enter the dosing cavity from the second water inlet cavity 3b and mix with the additives to achieve precise adjustment of the flow rate and concentration of the mixed liquid. Among them, the number of water outlets can be one or more. The water outlets can be arranged at the bottom or side of the second water inlet cavity 3b so that the water flow can smoothly flow into the dosing cavity. The size and shape of the water outlets need to be designed according to actual needs to ensure that the mixed liquid can be evenly and fully mixed with the additives. Exemplarily, multiple bent flow channels communicating with each other in sequence can be formed at one end of the second water inlet cavity 3b away from the second inlet 3d, and multiple water outlets can be formed at the bottom of each flow channel so that the water flow can flow into the dosing cavity.

[0062] As Figure 3 shown, according to some embodiments of the present application, the second inlet 3d and the first inlet 3c are arranged on the same side surface of the water box 3, and the first valve 1 and the second valve 2 are arranged adjacent to each other and fixedly connected.

[0063] Specifically, the water box 3 has multiple side surfaces. The second inlet 3d and the first inlet 3c can be arranged on the same side surface of the water box 3. In this way, it helps to simplify the connection of pipelines such as the first pipe 4 and the third pipe 6, reduce the pipeline length and complexity. At the same time, it can make the overall structure of the water box 3 more compact, which is beneficial to the installation and layout inside the laundry treatment device. The first valve 1 and the second valve 2 are arranged adjacent to each other and fixedly connected, which improves the integration of the first valve 1 and the second valve 2, helps to reduce the space occupied between the valves, can further improve the space utilization rate, and is also more convenient for the layout between the external water source and the water box 3.

[0064] In addition, concentrating the first inlet 3c and the second inlet 3d on one side of the water box 3 and fixedly connecting the first valve 1 and the second valve 2 also helps to form a neat and orderly internal structure, making the internal structure division clearer and more distinct, and can improve the replacement and maintenance convenience of each component.

[0065] As Figure 1 and Figure 4 shown, according to some embodiments of the present application, the dosing device 100 for a laundry treatment device further includes: a flow limiting device 8. The flow limiting device 8 is arranged on the first pipe 4. A flow limiting channel 8a is formed inside the flow limiting device 8. The flow limiting channel 8a is communicated with the first water inlet cavity 3a. The flow limiting device 8 is adapted to limit the fluid flow rate in the flow limiting channel 8a.

[0066] Specifically, the flow limiting device 8 can be arranged in the first pipe 4, upstream of the first inlet 3c. A flow limiting channel 8a is formed in the flow limiting device 8, and the flow limiting channel 8a communicates with the first water inlet cavity 3a of the water box 3. By restricting the flow rate of the fluid (water flow) in the flow limiting channel 8a, that is, the volume of the fluid passing through the flow limiting channel 8a per unit time, the flow velocity of the fluid on the inlet side of the flow limiting channel 8a can be increased, and accordingly, the dynamic pressure of the fluid on the inlet side increases. At the same time, due to the increase in dynamic pressure, the pressure energy of the fluid (mainly manifested as static pressure) will correspondingly decrease to maintain the conservation of the total energy (dynamic pressure + static pressure + potential pressure, and the potential pressure can be ignored in a horizontal pipeline). Therefore, due to the increase in flow velocity, the static pressure of the fluid near the outlet of the flow limiting channel 8a will decrease, so that the flow limiting device 8 can play a role in further limiting the flow and reducing the pressure, and further can reduce the pressure when the fluid enters the first water inlet cavity 3a from the first inlet 3c, which can avoid damaging the equipment due to the high pressure of the fluid. Therefore, an additional pressure relief port can be cancelled, and the washing medium can be prevented from flowing back from the pressure relief port to the space between the dosing component and the inner and outer drums of the laundry treatment equipment.

[0067] It should be noted that arranging the flow limiting device 8 in the first pipe 4 is only an exemplary embodiment of the present application. As Figure 1 shown, adding a flow limiting device 8 to the first pipe 4 can further enhance the effect of limiting the flow and reducing the pressure, and further ensure that the fluid is within the safe pressure range of the equipment; however, in some other embodiments of the present application, as Figure 2 shown, the flow limiting device 8 may not be arranged on the first pipe 4, and only the first valve 1 is used to control the flow rate and reduce the pressure of the washing medium, which can also fully meet the safety pressure requirements of the components and can fully protect the equipment from high-pressure damage, achieving the purpose of canceling the additional pressure relief port.

[0068] As Figure 5 shown, according to some embodiments of the present application, the flow limiting device 8 includes: a flow limiting plate 81, the flow limiting plate 81 is arranged in the flow limiting channel 8a and is adapted to block at least part of the fluid, and a plurality of flow limiting holes 81a are formed on the flow limiting plate 81.

[0069] Specifically, a flow-limiting plate 81 can be provided in the flow-limiting channel 8a. The flow-limiting plate 81 can span the entire cross-section of the flow-limiting channel 8a, or can be designed to cover a part of the cross-section of the flow-limiting channel 8a as required. The flow-limiting plate 81 can block at least part of the fluid in the flow-limiting channel 8a. It should be noted that this blocking does not completely prevent the fluid from flowing, but blocks at least part of the fluid from directly passing through the flow-limiting channel 8a. At least part of the fluid needs to bypass the blocking part on the flow-limiting plate 81 and then pass through the flow-limiting channel 8a through the flow-limiting holes 81a on the flow-limiting plate 81, so as to limit the fluid flow rate and change the fluid flow velocity. Specifically, when the fluid passes through the flow-limiting plate 81, due to the reduction of the flow area, the flow velocity of the fluid will increase on the inlet side of the flow-limiting channel 8a, so that the hydrodynamic pressure of the fluid on the inlet side increases, and the static pressure of the fluid near the outlet of the flow-limiting channel 8a can be reduced, thereby realizing the reduction of the fluid pressure on the outlet side of the flow-limiting channel 8a.

[0070] In addition, in some specific embodiments of the present application, the flow-limiting holes 81a can be configured as holes with regular shapes such as circular holes, rectangular holes or oval holes, etc., so as to facilitate production and manufacturing and improve the uniformity of flow distribution; in some other specific embodiments of the present application, the flow-limiting holes 81a can also be configured as special-shaped holes to provide more complex flow control characteristics or meet specific process requirements.

[0071] As Figures 1-5 shown, according to the clothing treatment device of the second aspect embodiment of the present application, the clothing treatment device includes: the dosing device 100 for the clothing treatment device described in any one of the above embodiments, and the technical effects generated are the same as those in the above embodiments, and will not be elaborated here.

[0072] In summary, the dosing device 100 for the clothing treatment device includes a first valve 1, a second valve 2, a water box 3, a dosing box, a first pipe 4, a second pipe 5, a third pipe 6 and a fourth pipe 7. Among them, the first pipe 4, the first water inlet cavity 3a of the water box 3 and the second pipe 5 define a first water inlet flow path to dissolve the additive and put it into the clothing treatment cavity. The first water inlet flow path is a continuous closed water path with one end communicating with an external water source and the other end communicating with the clothing treatment cavity. The first valve 1 can control the water flow rate flowing through the first water inlet flow path to limit the fluid flow rate in the first water inlet cavity 3a and reduce the fluid pressure, so as to avoid damage to components such as the dosing box and the water box 3 caused by too high pressure, and an additional pressure relief port can be cancelled to avoid the washing medium from flowing back from the pressure relief port to the space between the dosing box and the inner and outer barrels of the clothing treatment device, and the washing medium can directly act on the clothes completely, thereby improving the atomization bubble effect of the detergent and increasing the utilization rate of the detergent.
