Before water is fed, detergent is limited in the sub-chamber by the baffle 304 and is not thrown in the sub-chamber; in a period of time after the water inlet is started, the baffle 304 is still in a closed state, so that the detergent and the water are dissolved conveniently; the detergent is gradually dissolved along with the increase of the water inflow, the baffle plate 304 is gradually opened under the pressure action of the water flow, and the detergent enters the next sub-chamber along with the water flow and is finally put into the washing outer cylinder; when a certain amount of water is reached, the baffle 304 is completely opened, that is, the action opening of the baffle 304 is the maximum, and at this time, the solubility of the detergent is high, so as to accelerate the feeding of the detergent.
The water intake of the embodiments of the present invention, which allows the baffle 304 to be fully opened, may preferably be more than half of the maximum water level that can be accommodated in the main chamber.
Therefore, the detergent dispensing device provided by the embodiment of the invention can effectively solve the problems that solid or liquid detergent cannot be fully dissolved and foamed and liquid detergent put in by a user in advance flows into the washing outer barrel in advance, effectively improves the action effect of the detergent, improves the cleanliness of clothes and improves the satisfaction degree of the user.
In order to implement the above working process of the detergent dispensing device according to the embodiment of the present invention, specifically, the sub-chamber located at one end of the main chamber 301 uses the baffle 304 as a blocking sidewall for placing detergent; the sub-chamber at the other end of the main chamber 301 has a circumferential opening for dispensing detergent. Thus, when water is fed, the water firstly dissolves the detergent in the sub-chamber at one end and then gradually flows into the sub-chamber at the other end.
In addition, a plurality of baffles 304 can be arranged, the main chamber is divided into a corresponding number of sub-chambers by the plurality of baffles 304, and in order to further enhance the dissolving effect, the water inflow corresponding to the completely opened baffles 304 is gradually increased from the detergent placing end to the feeding end. Therefore, the detergent has better effects of gradual dissolution and gradual feeding, higher solubility and more uniform feeding.

Secondly, the step structure 307 can limit the position of the baffle 304, which is more beneficial to the resetting.
Finally, the incompletely dissolved detergent forms a water flow impact action at the position of passing through the stepped structure 307, and the dissolution of the detergent is accelerated.
Specifically, the middle of the main chamber 301 in the embodiment of the present invention is provided with a baffle 304, the baffle 304 divides the main chamber 301 into a first sub-chamber 301A and a second sub-chamber 301B, the first sub-chamber 301A contains detergent, and the second sub-chamber 301B contains detergent; the area of the baffle 304 is larger than the cross-sectional area of the first sub-chamber 301A and smaller than the cross-sectional area of the second sub-chamber 301B. In this way, movement of the baffle 304 within the second sub-chamber 301B is facilitated, while better conforming to the end face of the stepped structure 307 during resetting.
The arrangement of the baffle 304 in the detergent dispensing device according to the embodiment of the present invention may be various, and the detailed description thereof will be given with reference to the accompanying drawings, but the present invention is not limited to the above-described embodiment, and it is within the scope of the present invention to make modifications which are simple in the basic principle of the present invention and are well known to those skilled in the art.
Since the baffle 304 has the function of automatic reset, as a preferred embodiment of the present invention, the baffle 304 is installed in the main chamber through an elastic device 305, one end of the elastic device 305 is connected to the baffle 304, and the other end is directly or indirectly connected to the sidewall of the main chamber 301.
The elastic device 305 has a certain elasticity to the baffle 304 in a natural state, so that the baffle 304 is kept closed, when the water inflow reaches a certain amount, the pressure of the water overcomes the elasticity of the elastic device 305, the baffle 304 is gradually opened until the baffle is completely opened, and after the water inflow valve is closed and the water inflow is stopped, the elasticity of the elastic device 305 resets the baffle 304.
The embodiment of the invention realizes the automatic reset function of the baffle 304 through the elastic device 305, and the realization mode is simple.
As a preferred embodiment of the present invention, the other end of the elastic device 305 of the present embodiment is indirectly connected to the sidewall of the main chamber 301. Specifically, a mounting seat 306 is disposed in the main chamber 301, the mounting seat 306 spans between two side walls of the main chamber 301, and the elastic device 305 is mounted on the mounting seat 306. Through this kind of indirect mounting means, can carry out better design with resilient means 305 to the stress point of baffle 304 for the whole face of baffle 304 atress is more even, and the laminating is inseparabler when reseing, and the effect of holding the detergent is better.
As a preferred embodiment of the present invention, the elastic means 305 is a compression spring, and the mounting seat 306 is provided in a sub-chamber other than the sub-chamber for placing the detergent. Specifically, the mounting seat 306 is disposed in the second sub-chamber 301B, and the mounting seat 306 is a plate-shaped structure with two ends respectively connected to the inner walls of the two sides of the second sub-chamber 301B.
As a preferred embodiment of the present invention, a first auxiliary chamber 302 for containing a softener and/or a second auxiliary chamber 303 for containing a pre-washing detergent are further disposed in the box 300; the first auxiliary chamber 302 and/or the second auxiliary chamber 303 is provided with at least one baffle 304.
Because the softener is generally put in the rinsing procedure, the softener needs to be put in when the rinsing procedure is started, and the detergent dispensing device of the embodiment of the invention is combined with the control of the corresponding water inlet valve to realize the sequential putting function. During a washing program, the water inlet valve corresponding to the main chamber 301 is opened, the water in the main chamber 301 dissolves and puts in the detergent, and the water inlet valve corresponding to the first auxiliary chamber 302 is not opened, so that the softener is placed in the first auxiliary chamber 302 under the action of the baffle 304 until the washing machine performs a rinsing program, and the water inlet valve is opened to put in the softener.
In addition, if the washing machine has a pre-washing function, the detergent contained in the second auxiliary chamber 303 is mainly used for the pre-washing process, and needs to be put in the pre-washing process. Therefore, after the pre-washing procedure is started, the drain valve corresponding to the second auxiliary chamber 303 is controlled to be opened, and the detergent in the pre-washing procedure can be put in.
Preferably, the case 300 and the baffle 304 of the embodiment of the present invention are both formed by injection molding, so that the baffle is attached to the sealing surface under the elastic force of the elastic device 305, and inevitably, because the contact surface is not smooth enough, a very small gap L is formed, where L is less than 1 mm. Therefore, each chamber has no liquid residue, and detergents such as washing liquid or softener and the like put in each chamber by a user can not automatically and quickly flow into the washing outer barrel.
The panel 100 is arranged on the front side of the box body in the embodiment of the invention, and the panel 100 is matched with the front panel of the washing machine, so that the integration degree of the front panel of the washing machine is higher.

The user pushes the detergent dispensing device into the washing machine after each chamber has been filled with the respective solid or liquid detergent. After the washing machine is started, water enters the upper part of the detergent dispensing device and falls into the sub-chambers of the chambers.
For example, the solid or liquid detergent in the first sub-chamber 301A is fully dissolved, mixed and foamed with the incoming tap water in the first sub-chamber 301A, and as the more dissolved liquid accumulates, the baffle 304 can be pushed open, so that the end surface of the stepped structure 307 forms a larger distance L' with the baffle 304, and the mixed liquid leaks into the second sub-chamber 301B through the periphery of the baffle 304 and then flows into the washing outer cylinder for washing.
After the water inlet valve is closed, water does not enter any more, the water level of the first sub-chamber 301A is lower, and the distance between the baffle 304 and the end surface of the stepped structure 307 is smaller and smaller until the first sub-chamber is reset.
In addition:
1. the elastomeric means 305 is covered with a decorative feature to hide the elastomeric means 305 from view, improving the overall aesthetics.
2. The position of the baffle 304 varies and may be located at various locations, such as at the very end of the chamber.
3. The position of the elastic device 305 can be up, down, left and right of the baffle 304, and the number can be multiple.
Example two
As shown in fig. 5, the present embodiment differs from the above-described embodiments only in that: the elastic means 305 is a tension spring 308 and the mounting 306 is arranged in a sub-chamber other than the one for dosing the detergent. Specifically, the mounting seat 306 is disposed in the first sub-chamber 301A, and the mounting seat 306 is a plate-shaped structure with two ends respectively connected to the inner walls of two sides of the first sub-chamber 301A.
In addition, the upper end of the baffle 304 is arranged on the two side walls of the main chamber through a rotating shaft, so that the baffle 304 can swing by adopting the extension spring 308, the baffle 304 can be gradually opened, and the throwing process is more stable.
EXAMPLE III
As shown in fig. 6, the present embodiment differs from the above-described embodiments only in that: the structure of the baffle 304 with the same function can be realized by a specific structure, specifically, the baffle 304 is a wedge-shaped baffle, the small end of the wedge-shaped baffle is provided with a rotating shaft structure 309, and the rotating shaft structure 309 is rotatably installed on the side wall of the main chamber 301.
The baffle 304 of the present embodiment adopts a wedge-shaped baffle, which can save the elastic device 305 and the mounting seat 306 in the above-mentioned embodiment.
