[0076] 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.

[0077] The embodiment of the present application provides a liquid flow path switching structure for a clothes processing device (hereinafter sometimes referred to as "liquid flow path switching structure"), such as Figure 1 As shown, the liquid flow path switching structure 50 may include a first switching valve 51, which may be formed with a first switching valve inlet 511, a first switching valve first outlet 512, and a first switching valve second outlet 513. The first switching valve inlet 511 can only be connected to one of the first switching valve first outlet 512 and the first switching valve second outlet 513 at the same time, that is, only one flow path can be formed at the same time through the first switching valve 511.

[0078] The first switching valve inlet 511 can be connected to two water inlet flow paths, at least one of which can be provided with a water inlet check valve 54. At least one of the first switching valve first outlet 512 and the first switching valve second outlet 513 can be connected to two water outlet flow paths, at least one of which can be provided with a first water outlet check valve 55.

[0079] It is understood that this liquid flow path switching structure can be applied to a laundry treatment device including at least two water tubs, and can connect two water inlet paths and multiple water outlet paths. By cooperating with the switching valve and the check valve, switching between the multiple water outlet paths can be completed with relatively simple operation.

[0080] Furthermore, the liquid flow path switching structure may also include a second switching valve 52. The second switching valve 52 may be formed with a second switching valve inlet 521, a second switching valve first outlet 522, and a second switching valve second outlet 523. The second switching valve inlet 521 can only be connected to one of the second switching valve first outlet 522 and the second switching valve second outlet 523 at the same time. The second switching valve 52 can be connected to the second switching valve 51. Specifically, the first switching valve first outlet 512 of the first switching valve 51 can be connected to two water outlet flow paths; the first switching valve second outlet 513 of the first switching valve 51 can be connected to the second switching valve inlet 521 of the second switching valve 52. Through the above-mentioned two switching valves connected in series, the liquid flow path switching structure can meet the flow path control requirements of the clothing processing device including three water tubs.

[0081] The second switching valve first outlet 522 and the second switching valve second outlet 523 of the second switching valve 52 can each be connected to two water outlet paths. This means that the first switching valve 51 and the second switching valve 52 connected in series can form three sets of water outlet paths, each connected to the three water tubs. Each set of water outlet paths can include two water outlet paths, meeting the complex liquid flow path switching requirements of multi-drum laundry processing devices.

[0082] Preferably, at least one water outlet flow path connected to the first outlet 522 of the second switching valve may be provided with a second water outlet check valve 56. At least one water outlet flow path connected to the second outlet 523 of the second switching valve may also be provided with a third water outlet check valve 57. A check valve may be provided on at least one water outlet flow path connected to the switching valve outlet to prevent liquid or gas leakage in the water outlet flow path (particularly to prevent liquid or gas leakage in the water outlet flow path from affecting the operation of another water outlet flow path).

[0083] The first switching valve inlet 511 can connect to two water inlet channels, one of which can be equipped with a water inlet check valve 54, and the other with a water inlet switch valve 53. The two water inlet channels, each equipped with a check valve and a switch valve, can meet different water inlet requirements. For example, the water inlet channel equipped with the water inlet switch valve 53 can be used to introduce sterilized water, particularly silver ion sterilized water. The water inlet channel equipped with the water inlet check valve 54 can be used to introduce an additive diluent, and can particularly be connected to the additive container 30.

[0084] The embodiment of the present application also provides a clothes processing device, such as Figure 2 and Figure 3 As shown, it may include an additive container 30, a sterilization unit 80, and the aforementioned liquid flow path switching structure for the laundry treating apparatus.

[0085] The two water inlet paths connected to the first switching valve inlet 511 of the liquid flow path switching structure 50 can be connected to the additive holding part 30 and the sterilization part 80 respectively, so as to realize the two-way water inlet control of the additive and sterilization water in the clothing treatment device respectively. One water inlet path connected to the first switching valve inlet 511 can be connected to the additive holding part 30 via the water inlet check valve 54. The other water inlet path connected to the first switching valve inlet 511 can be connected to the sterilization part 80 via the water inlet switch valve 53. The liquid in the additive holding part 30 is usually extracted to flow by the extraction mechanism, so only a check valve is required. The sterilization part 80 can be directly connected to the water inlet valve. Since the water inlet valve has its own water pressure, a switch valve can be set to control the on and off of the flow path.

[0086] It is understood that the additive holding section 30 can be connected to the additive injection section 10 via a primary extraction mechanism 20, which can extract the additive from the additive injection section 10 and supply it to the additive holding section 30. The additive holding section 30 can also be directly or indirectly connected to a water inlet valve (e.g., the first water inlet valve FV1 in the figure) to supply water to the additive holding section 30 for diluting and flushing the additive. The sterilization section 80 can be a silver ion sterilization section, and in particular, can be a sterilization section capable of electrolyzing silver flakes to form silver ions. Water can flow from the water inlet valve (e.g., the second water inlet valve FV2 in the figure) through the sterilization section 80 to form sterilized water.

[0087] Specifically, the laundry processing apparatus may further include first and second extraction mechanisms 61, a first water tub 71, a second water tub 72, and a first vent 41. The first and second extraction mechanisms 61 may be connected to a water inlet valve (e.g., the third water inlet valve FV3 in the figure), and the first vent 41 may be connected to at least one water tub.

[0088] The first outlet 512 of the first switching valve can be connected to two water outlet paths. One of the water outlet paths connected to the first switching valve first outlet 512 can be connected to the first water tub 71 via the first water outlet check valve 55 and the first vent 41. The other water outlet path connected to the first switching valve first outlet 512 can be connected to the first water tub 71 via the first and second pumping mechanisms 61. The second outlet 513 of the first switching valve can be directly or indirectly connected to the second water tub 72.

[0089] It will be appreciated that when the laundry treatment apparatus is equipped with a vent connected to the tub, foam, liquid, etc. within the tub may enter the vent through the vent pipe, etc. Sterilization unit 80 is connected to the vent via first switching valve 51 to flush the potentially contaminated vent. This means that a single sterilization unit can sterilize both the tub and the vent.

[0090] The laundry processing apparatus may also include a third water tub 73. In this case, the liquid flow path switching structure 50 may include the aforementioned second switching valve and other related structures. The first outlet 522 of the second switching valve may be connected to the second water tub 72. The second outlet 523 of the second switching valve may be connected to the third water tub 73. This technical solution enables the liquid flow path switching structure to switch the liquid flow path between the three water tubs, improving the flow path control of a multi-drum laundry processing apparatus.

[0091] Furthermore, the clothing processing device can also include a second-level extraction mechanism 62 and a third-level extraction mechanism 63, and the second-level extraction mechanism 62 and the third-level extraction mechanism 63 can be connected to the water inlet valves respectively (for example, the second-level extraction mechanism 62 can be connected to the fourth water inlet valve FV4 in the figure, and the third-level extraction mechanism 63 can be connected to the fifth water inlet valve FV5 in the figure).

[0092] A water outlet connected to the first outlet 522 of the second switching valve can be connected to the second water tub 72 via the second secondary extraction mechanism 62. A water outlet connected to the second outlet 523 of the second switching valve can be connected to the third water tub 73 via the third secondary extraction mechanism 63. This technical solution allows one of the three water tubs to be filled with sterilizing water or additives while the remaining water tubs can be directly filled with water via the water inlet valve and the secondary extraction mechanism, thereby reducing the waiting time for each water tub in the multi-drum laundry processing device to operate.

[0093] Each tub of the laundry treatment device may be connected to one vent, or each tub may be provided with a separate vent. Figure 3As shown, when each tub is provided with a separate vent, the laundry treatment apparatus can include a second vent 42 and a third vent 43. Another water outlet flow path connected to the first outlet 522 of the second switching valve can be connected to the second tub 72 via the second water outlet check valve 56 and the second vent 42. Another water outlet flow path connected to the second outlet 523 of the second switching valve can be connected to the third tub 73 via the third water outlet check valve 57 and the third vent 43. It will be appreciated that providing a separate vent for each tub allows for greater flexibility in the design of the vent location, reduces the length of the vent pipes in some tubs, and saves space. The switching valve outlet is connected to the vent via a check valve, allowing the vent to be flushed with sterilized water while preventing leakage of liquid or air from the water outlet flow path.

[0094] Preferably, at least one of the first and second extraction mechanisms 61, the second and second extraction mechanisms 62, and the third and second extraction mechanisms 63 may include a venturi tube. The venturi tube may include a negative pressure interface that can be connected to one of the first outlet 512 of the first switching valve, the first outlet 522 of the second switching valve, and the second outlet 523 of the second switching valve, so as to utilize the venturi tube to draw the additive dilution liquid from the additive storage portion 30. Using a venturi tube can utilize the negative pressure generated when water is supplied to the water storage cylinder to extract the liquid from the additive storage portion, which can reduce manufacturing costs and energy consumption compared to using a pump-type extraction mechanism. The venturi tube operates by utilizing the Venturi effect generated by its pipe structure, making it less prone to failure than pump-type extraction devices, reducing the risk of water leakage.

[0095] The following briefly describes some of the beneficial effects of the above-mentioned embodiments of the present application.

[0096] The embodiments of the present application provide a liquid flow path switching structure for a laundry treatment device and a laundry treatment device that, through the coordination of a switching valve and a check valve, can quickly switch the liquid flow paths associated with at least two water tubs with relatively simple operations. This allows a multi-drum laundry treatment device to share a portion of the piping connecting multiple water tubs, simplifying the internal piping structure and conserving internal space. This solution also allows one of the multiple water tubs to be filled with sterilizing water or additives while the remaining tubs can be directly filled with water via a water inlet valve and a secondary extraction mechanism, reducing the waiting time for each water tub in the multi-drum laundry treatment device to operate.

[0097] It is understood that in this application, when the number of parts or components is not specifically limited, the number may be one or more, and the term "plurality" herein refers to two or more. 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.

[0098] 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.
