In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A laundry aid dispensing assembly 10 and a laundry treatment device 1 provided according to some embodiments of the present invention are described below with reference to fig. 1 to 4.

The embodiment of the utility model provides a washing assistant puts in subassembly 10 based on venturi 120's multi-mode utilizes the venturi effect principle, and when rivers crossed venturi 120, rivers become thin by thick, make venturi 120 expansion end form a negative pressure zone, through suction nozzle 122 intercommunication this negative pressure zone and the container of depositing washing assistant, take out venturi 120 with the washing assistant in the container. Through the use of cooperation flowmeter 140, can realize automatic ration extraction washing auxiliary agent to whether empty load according to flowmeter 140 judges the container and lacks the liquid, simple structure, low cost.

As shown in fig. 1, an embodiment of the present invention provides a detergent dispensing assembly 10, which includes an automatic dispensing assembly 100 for automatically dispensing detergent, and a water supply assembly 300 for controlling on/off of the automatic dispensing assembly 100. It is to be understood that the liquid entering through the liquid inlet 310 of the water supply assembly 300 is typically water, which is hereinafter described as an example to distinguish it from the washing aid.

Specifically, the automatic dosing assembly 100 includes a first flow path 110, a venturi 120, a first container 130, and a flow meter 140. Wherein, the inlet end of the first flow path 110 is communicated with the water supply assembly 300 to introduce the water flow into the first flow path 110. A venturi tube 120 is connected in series in the first flow path 110, and as described above, a negative pressure region is formed in the venturi tube 120 when water passes through the venturi tube 120. The negative pressure region of the venturi tube 120 is communicated to the first container 130 via the suction nozzle 122, and the first container 130 can store washing aids, including but not limited to washing liquid, softener, and disinfectant. Specifically, the first container 130 is provided with an injection port 132 so that a user injects the washing aid into the first container 130 in advance. When the water flows through the venturi tube 120, a pressure difference is generated between the first container 130 and the negative pressure region, so that the washing aid in the first container 130 can be sucked into the venturi tube 120, thereby achieving the automatic extraction of the washing aid. The suction nozzle 122 may also be connected in series with a flow meter 140 to detect the flow of the washing aid sucked into the venturi tube 120. The flow meter 140 has the advantages of low cost and simple metering process, and can conveniently measure the extracted amount of the washing aid only by reading the flow meter 140, and compared with a scheme using a quantitative box, the amount of the sucked washing aid is not required to be an integral multiple of the quantitative box, thereby being beneficial to realizing more accurate extracted amount control. In addition, whether the first container 130 is short of liquid can be determined according to whether the flow meter 140 is empty, and an additional liquid level detection device does not need to be arranged for the first container 130, so that the structure of the first container 130 is simplified, the production cost can be reduced, the washing assistant residue in the first container 130 can be reduced, and the mildew probability and the bacterial reproduction can be reduced. When the extraction amount meets the washing requirement, the water supply assembly 300 disconnects the automatic feeding assembly 100, i.e. the water flow is controlled not to enter the first flow path 110 any more, so that the automatic quantitative extraction of the washing aid can be realized.

Further, the washing aid feeding assembly 10 further comprises a liquid inlet assembly 200 for allowing liquid to pass through, and the water supply assembly 300 is further used for controlling the on-off of the liquid inlet assembly 200. When the pumping amount satisfies the washing requirement, the water supply assembly 300 may disconnect the automatic feeding assembly 100, and simultaneously, the water supply assembly 300 may further turn on the liquid inlet assembly 200, so that water flows into the second flow path 210 of the liquid inlet assembly 200, and water inlet may be continuously realized. By arranging the water supply assembly 300, the switching of different flow paths can be met, and a switch does not need to be arranged for the automatic feeding assembly 100 independently, so that the structure is simplified, the assembly efficiency is improved, and the cost can be reduced.

Specifically, the water supply assembly 300 includes a liquid inlet 310 capable of communicating with a water source, a liquid outlet 320 capable of communicating with the automatic feeding assembly 100 and the liquid inlet assembly 200, and a switch 330 capable of switching on and off any one of the liquid outlets 320, and switches on different liquid outlets 320 by controlling the switch 330, so that switching on of the automatic feeding assembly 100 and the liquid inlet assembly 200 can be realized, and the water supply assembly is simple in structure, low in cost and reliable in control. Specifically, the switch 330 may be at least two single-channel liquid inlet valves corresponding to the liquid outlets 320 one by one, or an integrated one-inlet-multiple-outlet liquid inlet valve.

In particular, an automatic dosing assembly 100 may be provided, where the washing aid is typically a washing liquid. Two automatic dosing assemblies 100 may also be provided, in which case the wash aids may be, for example, wash liquor and softener. More than two automatic dosing assemblies 100 may also be provided to increase the variety of automatically dosed detergent aids. It is understood that when the number of the automatic dispensing assemblies 100 is two or more, the switching member 330 may implement the automatic dispensing of the corresponding washing aid by turning on the different automatic dispensing assemblies 100. In addition, since different washing aids are added at different times in a single washing operation, the specific type of washing aid that can be stored in each first container 130 needs to be specified in order to ensure the washing effect by adding the washing aids as needed. In addition, the number of the liquid inlet assemblies 200 may be one or more.

The number of the liquid outlets 320 of the water supply assembly 300 may be equal to the sum of the numbers of the automatic feeding assembly 100 and the liquid inlet assembly 200, that is, one automatic feeding assembly 100 corresponds to one liquid outlet 320, one liquid inlet assembly 200 corresponds to one liquid outlet 320, or may be different from the sum of the numbers of the automatic feeding assembly 100 and the liquid inlet assembly 200, which may be smaller than the sum of the numbers of the automatic feeding assembly 100 and the liquid inlet assembly 200, that is, there is a case of sharing the liquid inlet 310, or may be larger than the sum of the numbers of the automatic feeding assembly 100 and the liquid inlet assembly 200, that is, one automatic feeding assembly 100 or one liquid inlet assembly 200 communicates two or more than two liquid inlets 310. However, at least one inlet 310 is required to be connected to an automatic feeding module 100, specifically to the inlet of the first flow path 110 of the automatic feeding module 100, and at least one inlet 310 is required to be connected to an inlet module 200, specifically to the inlet of the second flow path 210 of the inlet module 200.

Further, the liquid inlet assembly 200 further includes a second container 220 provided with a manual input port 222 and connected in series in the second flow path 210, a user can input the washing aid into the second container 220 through the manual input port 222, and when water flows through the second flow path 210, the washing aid in the second container 220 can be taken away, so that the manual input of the washing aid is completed. Through setting up second container 220, can make washing auxiliary put in subassembly 10 possess two kinds of functions of automatic ration extraction washing auxiliary and manual input washing auxiliary simultaneously, promoted the flexibility of product.

It will be appreciated that the automatic wash aid dosing program and the manual wash aid dosing program may be configured to execute the respective control programs when the user makes different selections. The control program of the washing assistant feeding assembly 10 can be kept unchanged, the automatic feeding assembly 100 and the liquid inlet assembly 200 are controlled to be switched on and off according to the program of automatically feeding the washing assistant by default, when the first container 130 is short of liquid, corresponding prompt information can be sent out to prompt the user of the type of the washing assistant which is short, and the user can automatically determine to feed the washing assistant or feed the washing assistant through the manual feeding port 222 of the second container 220.

Next, two embodiments of the water supply assembly 300 will be described by taking a case where the number of the automatic dispensing assemblies 100 is two, the number of the liquid inlet assemblies 200 is one, and the number of the liquid outlets 320 of the water supply assembly 300 is three as an example.

The switch 330 is a one-inlet-two-outlet liquid inlet valve, which can reduce the number of elements, reduce the occupied space, and make the control process simple and reliable. The inlet of the one-in-two-out inlet valve is connected to the inlet 310, and includes a configuration in which the inlet of the one-in-two-out inlet valve is configured as the inlet 310. In other embodiments, the switch 330 is two single-channel inlet valves.

The liquid separating box 340 has two inlets, and the two inlets are respectively communicated with two outlets of a one-inlet and two-outlet liquid inlet valve. The liquid separating box 340 is also provided with a first flow channel 342 and a second flow channel 344, the liquid inlet ends of the first flow channel 342 and the second flow channel 344 are respectively communicated with the two inlets of the liquid separating box 340, and the liquid outlet ends of the first flow channel and the second flow channel are converged to form a splayed structure. The first flow passage 342 is disposed toward the first liquid outlet 320a so that the liquid flowing out of the first flow passage 342 alone can flow out through the first liquid outlet 320 a. The second flow passage 344 is disposed toward the second liquid outlet 320b so that the liquid flowing separately from the second flow passage 344 can flow out through the second liquid outlet 320 b. The merged liquid outlet direction of the first flow channel 342 and the second flow channel 344 is towards the third liquid outlet 320c, for example, an included angle is formed between the center line of the first flow channel 342 and the center line of the second flow channel 344, and the bisector of the included angle is towards the third liquid outlet 320c, so that when the first flow channel 342 and the second flow channel 344 are simultaneously conducted, the liquid flowing from the two flow channels is flushed, the flowing direction of the liquid is changed accordingly, and the liquid flows out through the third liquid outlet 320c located between the first liquid outlet 320a and the second liquid outlet 320b, and three-direction liquid outlet can be realized by using two inlets. Because this minute box 340's structure is the feed liquor structure that clothing washing device had adopted among the correlation technique, through being applied to this minute box 340 water supply assembly 300, then only need improve the automatic structure of puting in among the correlation technique, can reduce the mould development to reduce the adjustment to the production line, help reducing product improvement cost.
