[0059] 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.

[0060] The embodiments of the present application provide a method for adding additives to a clothes processing device (hereinafter, sometimes referred to as "addition method"), such as Figure 1 and Figure 2As shown, the laundry treatment device may include an additive injection unit 10, a first extraction mechanism 20, an additive containing unit 30, and a water tub 50. The additive injection unit 10 may be connected to a first water inlet valve FV1, and the additive injection unit 10 may be connected to the additive containing unit 30 via the first extraction mechanism 20. Water may flow from the first water inlet valve FV1 through the additive injection unit 10 and the first extraction mechanism 20 into the additive containing unit 30.

[0061] like Figure 3 , Figure 4 and Figure 5 As shown, the additive delivery method may include the following steps which are repeated in a cycle:

[0062] S1: Turn on the first extraction mechanism 20 to extract the additive in the additive injection part 10 and supply it to the additive containing part 30. The first extraction mechanism 20 may include a pump. In step S1, the pump may be turned on to extract the additive in the additive injection part 10 and pump it into the additive containing part 30. Using the pump as a power source to suck the additive into the additive containing part 30 can ensure the feeding accuracy of the additive.

[0063] S2: Open the first water inlet valve FV1 to pass water into the additive receiving portion 30 to dilute the additive. Diluting and dissolving the additive before putting the additive into the water tub 50 can enhance the laundry treatment effect of the additive.

[0064] S3 : The liquid (the diluted liquid of the additive) in the additive container 30 is put into the water receiving tub 50 .

[0065] It can be understood that the additive can be fully diluted and dissolved before entering the water tub 50 through the above-mentioned repeated additive addition process, so as to give full play to or enhance the clothing treatment effect of the additive as much as possible. At the same time, the above-mentioned steps can also enhance the foaming effect of the additive and enhance the user's experience when using the clothing treatment device.

[0066] Further, the laundry processing device may further include a second extraction mechanism 40, and the additive containing part 30 may be connected to the tub 50 via the second extraction mechanism 40. In step S3, the second extraction mechanism 40 may extract the liquid in the additive containing part 30 and supply it to the tub 50. By providing the second extraction mechanism 40, active suction of the liquid containing the additive in the additive containing part 30 may be achieved. Moreover, after providing the second extraction mechanism 40, the arrangement positions of the additive injection part 10, the first extraction mechanism 20 and the additive containing part 30 may be more flexible. For example, the additive injection part 10, the first extraction mechanism 20 and the additive containing part 30 may be provided below the tub 50 (particularly below the laundry inlet of the tub), and the second extraction mechanism 40 may be provided above the tub 50 (particularly above the laundry inlet of the tub).

[0067] Preferably, Figure 6 As shown, the second extraction mechanism 40 may include a venturi tube, and the venturi tube may be connected to the second water inlet valve FV2 and the water bucket 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 holding portion 30. In step S3, the second water inlet valve FV2 may be opened, and when the water flows through the venturi tube, a negative pressure may be generated at the negative pressure interface 41 to extract the liquid (the diluent of the additive) in the additive holding portion 30 and supply it to the water bucket 50. Compared with the extraction mechanism using a pump, the negative pressure generated by the venturi tube to extract the liquid can reduce the manufacturing cost and energy consumption. The venturi tube can work by utilizing the venturi effect generated by its pipeline structure, and is less likely to fail than the pump extraction mechanism, which can reduce the risk of water leakage in the extraction mechanism.

[0068] More preferably, in step 2 and step S3, the first water inlet valve FV1 may be opened first to allow water to flow into the additive containing part 30, and then the first water inlet valve FV1 may be closed and the second water inlet valve FV2 may be opened. It is understood that the first water inlet valve FV1 and the second water inlet valve FV2 may be connected to the user's water pipe, and the simultaneous opening of the first water inlet valve FV1 and the second water inlet valve FV2 may reduce the water pressure of the second water inlet valve FV2, which may affect the negative pressure extraction effect of the venturi tube. Closing the first water inlet valve FV1 and then opening the second water inlet valve FV2 can ensure the effect of the venturi tube of the second extraction mechanism 40 in extracting the liquid in the additive containing part 30.

[0069] Further, the additive injection part 10 may include two types of additives. The additive injection part 10 may include a first injection part 11 and a second injection part 12. Among them, the first injection part 11 may be provided with a first additive opening and closing valve D1. The second injection part 12 may be provided with a second additive opening and closing valve D2 or a check valve. If the additive in the first injection part 11 is to be extracted, in step S1, before or at the same time as the first extraction mechanism 20 is opened, the first additive opening and closing valve D1 may be opened. In step S2, after closing the first extraction mechanism 20, the opened first additive opening and closing valve D1 is first closed, and then the first water inlet valve FV1 is opened. If the additive in the second injection part 12 is to be extracted, when the opening and closing valve is provided in the second injection part 12, the steps are the same as the steps of extracting the additive in the first injection part 11 mentioned above. When the check valve is provided in the second injection part 12, it is only necessary to keep the first additive opening and closing valve D1 closed, and the check valve will open with the opening of the first extraction mechanism 20 (the negative pressure generated by the first extraction mechanism, such as a pump, can push open the check valve).

[0070] When the additive injection part 10 includes two types of additives, it is necessary to select and switch the corresponding additive injection part (the first injection part 11 or the second injection part 12). The corresponding on-off valve can be opened before the extraction mechanism works, and the on-off valve can be closed after the extraction mechanism works to ensure the normal operation of the first extraction mechanism 20.

[0071] The additive injection part 10 may also include three types of additives (such as detergent, softener, care agent, etc.), and the additive injection part 10 may also include a third injection part 13. The second injection part 12 may be provided with a second additive opening and closing valve D2. The third injection part 13 may be provided with an opening and closing valve or a check valve. If the additive in the first injection part 11 or the second injection part 12 is to be extracted, in step S1, the first additive opening and closing valve D1 may be opened or the second additive opening and closing valve D may be opened before or at the same time as the first extraction mechanism 20 is opened. In step S2, after closing the first extraction mechanism 20, the opened first additive opening and closing valve D1 or the opened second additive opening and closing valve D2 may be closed first, and then the first water inlet valve FV1 may be opened.

[0072] If the additive in the third injection part 13 is to be extracted, when an on-off valve is provided in the third injection part 13 , the steps are the same as the steps of extracting the additive in the first injection part 11 or the second injection part 12 .

[0073] Preferably, the third injection part 13 may be provided with only a check valve but no opening and closing valve, and the check valve does not need to be actively operated, and it can be passively opened under the suction action of the first extraction mechanism 10. That is, the third injection part 13 may be provided with an additive check valve D3. In step S1, when the first extraction mechanism 20 is opened, the first additive opening and closing valve D1 and the second additive opening and closing valve D2 may be kept closed, and the additive check valve D3 may be opened as the first extraction mechanism 20 is opened.

[0074] Preferably, the number of repetitions of step S1 to step S3 in the aforementioned method of adding can be 3 to 8 times. Within this number of cycles, it can be ensured that the additive is fully diluted and dissolved without wasting time.

[0075] Preferably, a transition stage can be provided between every two adjacent circulation processes (steps S1 to S3). In the transition stage, the additive injection unit 10, the first extraction mechanism 20 and the first water inlet valve FV1 can all remain in a closed state. The transition stage can provide an interval to wait for each circulation operation to completely stop before entering the next feeding cycle. In the transition stage, ensure that each valve, extraction mechanism, etc. is actually closed, and the water flow in the pipeline stops flowing to prevent the water flow from affecting the feeding accuracy of the extraction mechanism.

[0076] The present application also provides a clothes treating device, which may include an additive injecting portion 10, a first extraction mechanism 20, an additive containing portion 30, and a water tub 50. The clothes treating device may use the aforementioned additive delivery method for clothes treating devices.

[0077] 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.

[0078] 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.

[0079] The clothes treating device may further include a vent 60. The vent 60 may be connected to the outside atmosphere, and the additive containing part 30 and the water tub 50 may be respectively connected to the vent 60 to balance the air pressure in the additive containing part 30 and the water tub 50. The vent structure of each component required for the clothes treating device is integrated to save space and facilitate maintenance.

[0080] 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.

[0081] The following briefly describes some of the beneficial effects of the above-mentioned embodiments of the present application.

[0082] The additive delivery method and the clothing treatment device provided by the embodiment of the present application include repeated cycles of additive extraction and dilution, which can fully dilute and dissolve the additive so that the additive can fully exert its clothing treatment effect. At the same time, the additive delivery method can also enhance the foaming effect of the additive and enhance the user's experience.

[0083] 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.

[0084] 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.
