Detailed ways

The present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a full understanding of the invention, but the invention may be practiced otherwise than as described herein. Limitations of the embodiments.

A detergent dispensing device and a washing machine in accordance with some embodiments of the present invention are described below with reference to FIGS. 1 through 14.

As shown in FIGS. 1 to 6, a detergent dispensing device according to an embodiment of the first aspect of the present invention is provided for a washing machine, comprising: a detergent box assembly 20, a dispenser box assembly 10, and a pumping assembly 30.

Specifically, the detergent box assembly 20 is internally provided with a water flow passage 24 and a mixing chamber 25 having a water inlet 241 and an automatic delivery flushing hole 242 having a flushing inlet communicating with the automatic dispensing flushing hole 242. 251 and a total outlet 252 in communication with the inner tub of the washing machine; the dispenser box assembly 10 is mounted on the detergent box assembly 20, and has a storage chamber 111 formed therein, the storage chamber 111 having a liquid suction port 112; and the pumping assembly 30 The input port is in communication with the liquid suction port 112, and the output port thereof communicates with the mixing chamber 25 for feeding the agent in the storage chamber 111 into the mixing chamber 25.

The detergent delivery device provided by the embodiment of the first aspect of the present invention prevents the detergent from entering the water inlet pipe by separately separating the water flow and the injection agent into the mixing chamber 25, and thus does not appear when the reflux phenomenon occurs. Detergent contamination of the user's household water source.

Specifically, in the prior art, the detergent and the water flow are mixed in the water inlet pipe and then enter the mixing chamber 25, that is, the detergent and the water flow share a pipeline into the detergent box, and the pipeline is directly connected to the user's household water source. Therefore, once the recirculation phenomenon occurs, the detergent remaining in the water inlet pipe will flow back to the water source together with the water flow, causing pollution of the user's household water source. In the present application, the injection agent in the storage chamber 111 is directly pumped into the mixing chamber 25 by the pumping assembly 30, and the water flows through the water inlet pipe into the water flow passage 24 in the detergent box assembly 20, and enters the mixing chamber through the flush inlet 251. 25, that is, the agent and the water flow are separately injected into the mixing chamber 25, and the agent and the water flow are not contacted and mixed before entering the mixing chamber 25. Therefore, the prior art automatic placement and waterway integrated design are avoided, and the agent remains in the water. The situation in the pipeline effectively solves the problem of detergent polluting the user's household water source.

Further, the flushing inlet 251 is located below the automatic dispensing flushing hole 242, as shown in Figure 6, the total outlet 252 is located below the flushing inlet 251, as shown in Figures 1 and 3.

The flushing inlet 251 is located below the automatic dispensing flushing hole 242, so that the water flow can automatically flow into the mixing chamber 25 under the action of gravity, as shown in FIG. 6, without additionally providing a structure for driving the water into the mixing chamber 25, thereby simplifying the product. The structure is capable of scouring the agent in the mixing chamber 25, and is beneficial for the agent to be diluted and then into the inner tub; similarly, the total outlet 252 is located below the flushing inlet 251 to facilitate the action of water flow and detergent in gravity. The automatic flow into the inner tub, as shown in Figure 6, also helps to simplify the product structure.

When the water flow in the water flow channel 24 flows to the automatic flushing hole 242, the water can flow directly downward under the action of gravity. Entering the mixing chamber 25, as shown in FIG. 6, the structure is simple; the opening of the flushing inlet 251 is directed toward the automatic flushing hole 242, and the opening of the flushing inlet 251 is upward, just facing the outlet of the automatic flushing hole 242 downward. The water flow automatically discharged into the flushing hole 242 can directly enter the mixing chamber 25, as shown in FIG. 6, the flow path is short, and the winding is not required, and the structure is relatively simple; meanwhile, the speed of the water flowing into the mixing chamber 25 The direction is downward, so that the flushing effect of the agent is better, and the agent is directly washed downward to drive it into the inner tub quickly, thereby effectively avoiding the upward flow or splashing of the agent into the water flow channel 24.

Further, the output port of the pumping assembly 30 is in communication with the mixing chamber 25 through the flushing inlet 251, as shown in FIG.

The output port of the pumping assembly 30 is in communication with the mixing chamber 25 through the flushing inlet 251, i.e., the output port of the pumping assembly 30 is directly connected to the flushing inlet 251, so that no additional openings are required in other portions of the mixing chamber 25, and no additional The sealing structure is arranged, thereby simplifying the structure of the detergent dispensing device; at the same time, the distance between the output port of the pumping assembly 30 and the automatic delivery flushing hole 242 is relatively close, as shown in FIG. The agent can contact the water stream earlier, thereby prolonging the mixing time with the water stream, facilitating the uniform mixing of the agent and the water stream before entering the inner barrel, thereby improving the use effect of the agent.

Preferably, the flushing inlet 251 is provided with a guiding portion 253. The guiding portion 253 is provided with a connecting port 2531 communicating with the output port of the pumping assembly 30 and a guiding groove 2532 communicating with the connecting port 2531. The upper end of the guiding groove 2532 closes the lower end. Open, as shown in Figure 8.

A guiding portion 253 is disposed at the flushing inlet 251, and an output port of the pumping assembly 30 is connected to the connecting port 2531 of the guiding portion 253. The discharging agent enters the mixing chamber 25 through the connecting port 2531 and the guiding groove 2532 in sequence, due to the upper end of the guiding groove 2532. The closed lower end is open, so that the agent can only flow downward into the mixing chamber 25, and further avoids the upward flow or splashing of the agent into the water flow passage 24, and also prevents the water from entering the pumping assembly 30 to some extent. .

In any of the above embodiments, the number of the storage chambers 111 is plural. As shown in FIG. 9, the number of the automatic delivery flushing holes 242 is also plural, as shown in FIG. 4, and a plurality of automatic flushing holes are provided. The 242 is in one-to-one correspondence with the plurality of storage chambers 111 by the pumping assembly 30.

A plurality of storage chambers 111 are disposed in the dispenser box assembly 10. Different storage chambers 111 can store different dispensing agents, such as storage detergents and storage softeners, so that the user can select according to personal preferences and personal needs. Therefore, the user's different laundry requirements are satisfied, and the user experience is improved; correspondingly, the number of automatic delivery flushing holes 242 opened by the water flow channel 24 is also plural, and is corresponding to the plurality of storage cavities 111 one by one to ensure each The liquid to be extracted in the storage chamber 111 can be flushed by the water stream, mixed with the water stream and then entered into the inner tub.
