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] Clothes processing devices require a pumping mechanism to deliver detergent and other additives needed for processing clothes into the water tub. However, there's often a height difference between where the detergent is stored and where the additives are added to the water tub. This height difference creates a significant pressure on the pumping mechanism, which in turn reduces its lifespan and can potentially cause leakage. Furthermore, using a pumping mechanism with a high pressure capacity often reduces the accuracy of detergent delivery. Utility Model Content

[0050] The following describes exemplary embodiments of the present application 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 embodiments 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 dispensing structure may include an additive injection unit 10, a first extraction mechanism 20, an additive storage unit 30, and a second extraction mechanism 40. The additive injection unit 10 may be connected to the additive storage unit 30 via the first extraction mechanism 20. The first extraction mechanism 20 is capable of extracting the additive from the additive injection unit 10 and supplying it to the additive storage unit 30. The additive storage unit 30 may be connected to the water tub 50 via the second extraction mechanism 40. The second extraction mechanism 40 is capable of extracting the liquid (particularly a mixture of the additive and water) in the additive storage unit 30 and supplying it to the water tub 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. This can increase the service life of the extraction mechanism and reduce the risk of water leakage in the extraction mechanism. 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 precision 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 higher level in the laundry processing apparatus than the first extraction mechanism 20. That is, the second extraction mechanism can be used to extract liquid from a lower position to a higher position.

[0053] The first extraction mechanism 20 may include a first pump that 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 that may connect the additive receiving portion 30 and the tub 50 to extract the liquid in the additive receiving portion 30 and supply the liquid to the tub 50 .

[0055] When both the first extraction mechanism 20 and the second extraction mechanism 40 include pumps, it is understood that the first pump primarily extracts the additive and requires a higher extraction accuracy. The second pump primarily lifts the liquid (and the second pump must extract a relatively large amount of the additive dilution liquid), requiring a higher pressure bearing capacity. Therefore, the extraction accuracy of the first pump can be higher than that of the second pump, while 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 (no second pump is provided). The venturi tube may connect the second water inlet valve FV2 and the water tub 50 to allow water to flow into the water tub 50. The venturi tube may be formed with a negative pressure port 41, which may be connected to the additive container 30. When water flows from the second water inlet valve FV2 through the venturi tube and into the water tub 50, a negative pressure is generated at the negative pressure port 41. This negative pressure can be used to extract the liquid in the additive container 30 and supply it to the water tub 50.

[0057] As can be appreciated, using a venturi tube as the primary structure of the second extraction mechanism 40 utilizes the negative pressure generated when water is supplied to the water tub 50 to extract the liquid from the additive container 30. This reduces manufacturing costs and energy consumption compared to the previously described solution using a pump as the second extraction mechanism 40. Furthermore, the venturi tube utilizes the Venturi effect generated by its piping structure, making it less prone to failure than a pump, effectively avoiding or reducing risks such as water leakage.

[0058] Furthermore, the additive container 30 can be directly or indirectly connected to the first water inlet valve FV1 to allow water to flow into the additive container 30. The flow of water into the additive container 30 can dilute and dissolve the additive injected therein, allowing the diluted additive to enter the water tub 50 through the second extraction mechanism 40, thereby improving the laundry treatment effect of the additive.

[0059] The first water inlet valve FV1 can be connected to the additive container 30 via the first water channel L1 and the second water channel L2. The first water channel L1 can be connected to the additive container 30 indirectly via the additive injection unit 10 and the first extraction mechanism 20. The second water channel L2 can be directly connected to the additive container 30 without passing through the additive injection unit 10 and the first extraction mechanism 20. The first water inlet valve FV1 can be connected to a switching valve that can connect the first water channel L1 and the second water channel L2 to switch between the first water channel L1 and the second water channel L2.

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

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

[0062] Positioning the first extraction mechanism 20 below the water tub 50 and the second extraction mechanism 40 above the water tub 50 allows additives located at the bottom of the laundry treatment apparatus to be drawn to the upper portion (top) of the water tub 50 and injected into the tub 50. Injecting the diluted additive from the upper portion of the water tub 50 improves the laundry treatment effect and user experience. During the additive delivery process, the first extraction mechanism 20 is solely used to extract the additive from the additive injection portion 10 to the additive storage portion 30, eliminating the need to transport the additive to an elevated location. The second extraction mechanism 40 is used to extract the additive to the upper portion (top) of the water tub 50. Using two (two-stage) extraction mechanisms to extract liquid in stages (particularly when the second extraction mechanism includes a venturi tube) effectively reduces the pressure on the extraction mechanism when only a single extraction mechanism is used to deliver liquid to an elevated location.

[0063] like Figure 4 As shown, the first extraction mechanism 20, the additive holding portion 30, the first water path L1 of the holding portion and the second water path L2 of the holding portion 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 dispensing structure may further include an additive storage section 80, which can be connected to the additive injection section 10 to supply additives. The additive storage section 80 may form a cavity to accommodate an additive storage box storing one or more additives. The opening direction of the cavity may be the same as the opening direction of the water tub 50. The additive storage box of the additive storage section is rationally arranged to facilitate user replacement of the additive storage box. The additive storage box may include multiple independent spaces to respectively accommodate various additives. For example, the additive storage box may store a conditioner, a detergent, and a softener.

[0065] In accordance with the structure of the additive storage portion 80 (and the additive storage box), the additive injection portion 10 may include one or more of a care agent injection portion 11, a detergent injection portion 12, and a softener injection portion 13. The additive injection portion 10 may be adapted to inject 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 communicate with 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 integrated ventilation structure of the various components required for the laundry treatment device can save space and facilitate maintenance.

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

[0069] It will be appreciated that when water is added to the additive container 30 to dilute the additive, foam may form within the additive container 30, which may then enter the vent 60 through the vent duct. Furthermore, when the water tub 50 is treating laundry, foam, liquid, and the like may also enter the vent 60 through the vent duct. Therefore, the vent 60 may be formed with an overflow chamber to accommodate liquid and / or foam that enters the vent 60 from the additive container 30 and / or the water tub 50. The provision of the overflow chamber prevents liquid and / or foam that overflows from the vent duct of the additive container 30 from directly spilling outside the laundry treatment apparatus.

[0070] The laundry treatment device may further include a silver ion sterilization unit 70. Water flowing through the silver ion sterilization unit 70 forms silver ion sterilized water. The silver ion sterilization unit 70 may be connected to the third water inlet valve FV3 and the water tub 50 to supply sterilized 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 sterilized water rinses the vent 60 before entering the water tub 50, thereby simultaneously rinsing the vent 60 (particularly the overflow chamber of the vent).

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

[0072] The additive dispensing structure for a clothing treatment device and the clothing treatment device provided in the embodiments of the present application can avoid the high pressure on a single extraction mechanism by providing 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 water leakage caused by the extraction mechanism being subjected to high pressure for a long time. The provision of two extraction mechanisms for extracting additives and supplying additives to the water tub, respectively, can also ensure that the additive dispensing structure has a high additive dispensing 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 portion, which can reduce manufacturing costs and energy consumption compared to the solution using a pump-type mechanism. In addition, the venturi tube works by utilizing the venturi effect generated by its pipe structure, which is less prone to failure than a pump-type mechanism and can effectively avoid or reduce the risk of water leakage.

Where the number of parts or components is shown in the drawings and / or described in the specification as a specific number, such as two, three, or four, the specific number is generally illustrative and not restrictive, and may be understood as a plurality, i.e., two or more. However, this does not mean that this 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 based on the teachings of the present application without departing from the scope of the present application.
