Description

Technical Field

[0001] The present application relates to the technical field of clothing processing, and in particular to an additive dispensing structure for a clothing processing device and a clothing processing device. Background Art

[0002] The clothes treatment device needs to use an extraction mechanism to supply detergent and other additives required for clothes treatment to the water tub, and there is usually a height difference between the location where the detergent is stored and the location where the additive is injected into the water tub. This height difference will cause the extraction mechanism to bear a large pressure, thereby affecting the service life of the extraction mechanism and may cause the extraction mechanism to leak, etc. At the same time, if the clothes treatment device uses an extraction mechanism with a large pressure bearing capacity, it will often lead to a decrease in the detergent delivery accuracy of the extraction mechanism.

[0050] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0051] The embodiment of the present application provides an additive delivery structure for a clothes treating device (hereinafter, sometimes referred to as "delivery structure"), which is used to deliver additives into a water tub of the clothes treating device. Figure 1 and Figure 2 As shown, the dosing structure may include an additive injection unit 10, a first extraction mechanism 20, an additive container 30, and a second extraction mechanism 40. The additive injection unit 10 may be connected to the additive container 30 via the first extraction mechanism 20, and the first extraction mechanism 20 may extract the additive in the additive injection unit 10 and supply it to the additive container 30. The additive container 30 may be connected to the water tank 50 via the second extraction mechanism 40, and the second extraction mechanism 40 may extract the liquid (especially the mixed liquid of the additive and water) in the additive container 30 and supply it to the water tank 50.

[0052] It can be understood that by setting up two (two-stage) extraction mechanisms, the pressure of the extraction mechanism can be reduced (especially the pressure of the extraction mechanism used to extract liquid from a lower place to a higher place) compared to the technical solution of using only one extraction mechanism. In turn, the service life of the extraction mechanism can be increased and the risk of water leakage in the extraction mechanism can be reduced. In this embodiment, the first extraction mechanism 10 can only be responsible for extracting additives without having to undertake the operation of lifting liquid, so an extraction mechanism with higher accuracy and lower pressure can be used to improve the accuracy of additive delivery. Figure 3 As shown, the second extraction mechanism 40 can be located at a height higher than the first extraction mechanism 20 in the laundry processing device. That is, the second extraction mechanism can be used to extract liquid from a lower place to a higher place.

[0053] The first extraction mechanism 20 may include a first pump, and the first pump may be used to extract the additive in the additive injection portion 10 and supply the additive to the additive receiving portion 30 .

[0054] The second extraction mechanism 40 may include a second pump, and the second pump may connect the additive accommodation portion 30 and the tub 50 to extract the liquid in the additive accommodation portion 30 and supply it to the tub 50 .

[0055] When both the first extraction mechanism 20 and the second extraction mechanism 40 include pumps, it can be understood that the first pump is mainly responsible for extracting the additive, and has a higher extraction accuracy requirement; the second pump is mainly responsible for lifting the liquid (and the second pump needs to extract relatively more diluent of the additive), and has a higher pressure bearing capacity requirement. Therefore, the extraction accuracy of the first pump can be higher than that of the second pump, and the pressure bearing capacity of the second pump can be higher than that of the first pump.

[0056] Preferably, Figure 5 and Figure 6 As shown, the second extraction mechanism 40 may include a venturi tube (the second pump is no longer provided), and the venturi tube may connect the second water inlet valve FV2 and the water tub 50 to pass water into the water tub 50. The venturi tube may be formed with a negative pressure interface 41, and the negative pressure interface 41 may be connected to the additive containing part 30. When the water flows from the second water inlet valve FV2 through the venturi tube into the water tub 50, a negative pressure can be generated at the negative pressure interface 41, and the liquid in the additive containing part 30 can be extracted and supplied to the water tub 50 by using the negative pressure.

[0057] It can be understood that the use of the venturi tube as the main structure of the second extraction mechanism 40 can utilize the negative pressure generated when water is supplied to the water tank 50 to extract the liquid in the additive receiving portion 30, which can reduce the manufacturing cost and energy consumption compared to the aforementioned solution of using a pump as the second extraction mechanism 40. In addition, the venturi tube works by utilizing the venturi effect generated by its pipeline structure, and is less prone to failure than a pump, which can effectively avoid or reduce the risk of water leakage.

[0058] Furthermore, the additive containing part 30 can be directly or indirectly connected to the first water inlet valve FV1 to pass water into the additive containing part 30. Passing water into the additive containing part 30 can dilute and dissolve the additive injected therein, so that the additive is diluted and then enters the water holding tub 50 through the second extraction mechanism 40, which can improve the laundry treatment effect of the additive.

[0059] The first water inlet valve FV1 may be connected to the additive container 30 through the first water path L1 of the container and the second water path L2 of the container, respectively. The first water path L1 of the container may be connected to the additive container 30 through the additive injection part 10 and the first extraction mechanism 20 (i.e., indirectly connected). The second water path L2 of the container may be directly connected to the additive container 30 without passing through the additive injection part 10 and the first extraction mechanism 20. The first water inlet valve FV1 may be connected to a switching valve, which may be connected to the first water path L1 of the container and the second water path L2 of the container, respectively, to switch between the first water path L1 and the second water path L2 of the container.

[0060] It can be understood that the first water path L1 of the receiving part can be used to supply additives to the additive receiving part 30, and after the additives are added, water can be used to rinse the additive injection part 10 and the first extraction mechanism 20. The second water path L2 of the receiving part can share the water flow when the water flow of the first water inlet valve FV1 is large, thereby improving the operating stability of the clothing treatment device.

[0061] Further, the first extraction mechanism 20 of the additive delivery structure may be disposed below or at the lower portion of the tub 50. Preferably, the first extraction mechanism 20 may be disposed below the tub 50. In particular, the first extraction mechanism 20 may be disposed below the clothing inlet of the tub 50. The second extraction mechanism 40 may be disposed above or at the upper portion of the tub 50. Preferably, the second extraction mechanism 40 may be disposed above the tub 50. In particular, the second extraction mechanism 20 may be disposed above the clothing inlet of the tub 50.

[0062] The first extraction mechanism 20 is arranged below the water tub 50 and the second extraction mechanism 40 is arranged above the water tub 50, so that the additive arranged at the bottom of the clothing treatment device can be extracted to the upper part (upper part) of the water tub 50 and injected into the water tub 50. Injecting the diluted additive into the water tub from the upper part of the water tub 50 can improve the clothing treatment effect and user experience. In the process of adding the above-mentioned additive, the first extraction mechanism 20 is only used to extract the additive from the additive injection part 10 to the additive containing part 30, without transporting the additive to a high place. The second extraction mechanism 40 is used to extract the additive to the upper part (upper part) of the water tub 50. Using two (two-stage) extraction mechanisms to extract liquid in sections (especially when the second extraction mechanism includes a venturi tube) can effectively alleviate the pressure of the extraction mechanism when only a single extraction mechanism is used to transport liquid to a high place.

[0063] like Figure 4 As shown, the first extraction mechanism 20, the additive containing part 30, the first water path L1 of the containing part and the second water path L2 of the containing part can be integrated to reduce the length of the water flow path and save space (especially the bottom space of the clothing treatment device, that is, the space below the water tub).

[0064] like Figure 3 , Figure 5 and Figure 6 As shown, the delivery structure may further include an additive storage portion 80, which may be connected to the additive injection portion 10 to supply additives. The additive storage portion 80 may form a cavity to accommodate an additive storage box storing one or more additives, and the opening direction of the cavity may be the same as the opening direction of the water tank 50. The layout of the additive storage box of the additive storage portion is reasonable, which is convenient for users to replace the additive storage box. The additive storage box may include multiple independent spaces to accommodate multiple additives respectively. Exemplarily, the additive storage box may store care agents, detergents, and softeners.

[0065] In accordance with the structure of the additive storage unit 80 (and the additive storage box), the additive injection unit 10 may include one or more of a care agent injection unit 11, a detergent injection unit 12, and a softener injection unit 13. The additive injection unit 10 may be adapted to the injection of different types of additives according to actual needs.

[0066] The embodiment of the present application also provides a clothes processing device, such as Figure 3 , Figure 5 and Figure 6 As shown, it may include a water tub 50, a vent 60 and the aforementioned additive delivery structure for a laundry treating apparatus.

[0067] The vent 60 can be connected to the outside atmosphere, and the additive container 30 and the water tub 50 can be connected to the vent 60 respectively to balance the air pressure in the additive container 30 and the water tub 50. The vent structure of each component required for the laundry treatment device is integrated to save space and facilitate maintenance.

[0068] Further, such as Figure 3 As shown, the vent 60 can be integrated with the second extraction mechanism 40, that is, the vent 60 and the second extraction mechanism 40 can be both disposed above the water tub 50 to further save space and make the structure more compact.

[0069] It can be understood that when water is poured into the additive containing part 30 to dilute the additive, foam may be formed in the additive containing part 30, and the foam may enter the vent part 60 through the ventilation duct. In addition, when the water holding tub 50 processes clothes, foam, liquid, etc. may also enter the vent part 60 through the ventilation duct. Therefore, the vent part 60 may be formed with an overflow cavity, which can accommodate liquid and / or foam entering the vent part 60 from the additive containing part 30 and / or the water holding tub 50. The provision of the overflow cavity can prevent the liquid and / or foam overflowing from the ventilation duct of the additive containing part 30 from directly overflowing to the outside of the clothes processing device.

[0070] The clothing treatment device may further include a silver ion sterilization unit 70, and silver ion sterilization water may be formed when water flows through the silver ion sterilization unit 70. The silver ion sterilization unit 70 may be connected to the third water inlet valve FV3 and the water tub 50 to supply sterilization water to the water tub 50. Preferably, the silver ion sterilization unit 70 may also be connected to the water tub 50 via the vent 60, so that the silver ion sterilization water flushes the vent 60 and then passes into the water tub 50, so as to flush the vent 60 (especially the overflow cavity of the vent) at the same time.

[0071] The following briefly describes some of the beneficial effects of the above-mentioned embodiments of the present application.

[0072] The additive delivery structure for a clothing treatment device and the clothing treatment device provided in the embodiment of the present application can avoid a single extraction mechanism from bearing too much pressure by setting a first extraction mechanism and a second extraction mechanism, thereby increasing the service life of the extraction mechanism and avoiding or alleviating the phenomenon of leakage caused by the extraction mechanism bearing too much pressure for a long time. The two extraction mechanisms are respectively used to extract additives and supply additives to the water tub, and can also ensure that the additive delivery structure has a high additive delivery accuracy. Furthermore, the use of a venturi tube as the main structure of the second extraction mechanism can utilize the negative pressure generated when supplying water to the water tub to extract the liquid in the additive holding part, which can reduce manufacturing costs and energy consumption compared to the solution using a pump mechanism. In addition, the venturi tube works by utilizing the venturi effect generated by its pipeline structure, and is less prone to failure than a pump mechanism, which can effectively avoid or reduce the risk of leakage.

[0073] It is understood that in the present application, when the number of parts or components is not particularly limited, the number may be one or more, and the multiple here means two or more. For the case where the number of parts or components shown in the drawings and / or described in the specification is a specific number such as two, three, four, etc., the specific number is usually exemplary and not restrictive, and it can be understood as multiple, that is, two or more, but this does not mean that the present application excludes the case of one.

[0074] It should be understood that the above embodiments are merely exemplary and are not intended to limit the present application. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present application without departing from the scope of the present application.
