The other is that a liquid storage box is arranged on the washing machine, a user pre-throws the additive into the liquid storage box structure of the washing machine in advance, and the additive is flushed into a washing machine barrel by utilizing the water inlet of the washing machine. The prior impeller type washing machine is generally provided with a feeding device which directly communicates a liquid storage box with the inside of a washing machine barrel through a water outlet so that additives flowing out of the liquid storage box directly flow into the barrel. Due to the lack of an integrated water channel, the additive is directly put in due to the lack of premixing, and the problem that the additive cannot be effectively utilized due to uneven distribution easily exists.

However, the existing additive feeding device with an integrated waterway generally integrates the integrated waterway into the top cover of the feeding device, and the feeding device adopting the above structure needs to flow the additive in the liquid storage box at the middle part upwards into the integrated waterway in the top cover and then downwards to the water outlet at the bottom to flow out. The feeding device needs to change the water flow direction for the second time, so that the feeding device needs to be provided with a complex water path structure, the feeding of the additive is not facilitated, the additive residue is easy to generate, and the cost of the feeding device is increased.

In addition, the current device of puting in is generally that, and the stock solution box is linked together through external pipeline and integrated water route, and this just makes the device of puting in still need carry out the piping erection alone for the assembly of puting in the device is complicated.

Other washing assemblies for agitating the water flow and washing the laundry may be provided in the tub, such as: impellers, mixing columns, and the like.

As shown in fig. 1 to 9, in the embodiment, the washing machine is a pulsator washing machine, and includes a tub disposed in a housing, an axis of the tub is disposed vertically, and a tub opening is opened upward. In this embodiment, the casing of the washing machine includes a control panel base 200 disposed at the top, the dispensing module 100 is installed inside the control module 200, and the control panel base 200 is provided with an opening 20 opposite to the drawing opening 19 of the insertion groove 3 of the dispensing module 100. In this embodiment, the control panel base 200 of the washing machine is annular, the middle part of the annular control panel base 200 forms a clothes input opening, the inside of the annular control panel base 200 is hollow to form an installation cavity, the input module 100 is installed in the installation cavity, and the inner peripheral wall of the annular control panel base 200 is provided with an opening 20 for the liquid storage box 2 to pass through. Preferably, the opening 20 is located on a rear side of the inner peripheral wall of the annular control tray 200 to facilitate the user's drawing access to the cartridge 2.

In this embodiment, the body 1 of the drop module is assembled on the inner wall of the control panel base 200, and the body 1 can directly enclose the insertion groove 3; also can enclose body 1 and control panel seat 200 inner wall jointly and enclose into the inserting groove 3 that supplies the corresponding pull installation of liquid storage box 2, the opening of inserting groove 3 is in the body 1 surface of throwing in the module, forms the pull mouth 19 that supplies liquid storage box 2 to pass. The openings 20 on the control panel base 200 and the drawing openings 19 on the body 1 of the putting module 100 are arranged in a one-to-one opposite manner, so that the liquid storage box 2 can be correspondingly inserted and installed in the insertion groove 3 after sequentially passing through the openings 20 and the drawing openings 19.

In this embodiment, put in and set up three liquid storage box 2 on the module 100, can hold different types of additive in each liquid storage box 2 respectively, for example: the washing machine comprises a washing machine body, a fabric washing machine body and the like, wherein the washing machine body is provided with a washing machine body, the washing machine body is provided with a detergent, a flavoring agent, a softener, a disinfectant and the like, so that different types of additives can be respectively or combined to correspondingly put in a mode, and the different types of additives are correspondingly used for correspondingly treating clothes when different types of programs are correspondingly executed correspondingly. Meanwhile, in the embodiment of the present invention, detergents with different concentrations may be stored in each liquid storage box 2 of the dosing module, for example: the washing machine is super-concentrated, ordinary, low-foam and the like, so that when the washing machine executes different washing programs, corresponding types of detergents are put in correspondingly, corresponding washing of different clothes is achieved, and the purpose of improving the washing effect of the washing machine is achieved.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
