Embodiment 1

[0080] like figure 1 and Figure 4 As shown, a washing machine automatic dispensing device described in this embodiment is equipped with a first liquid storage box 1 and a second liquid storage box 2, wherein the first liquid storage box 1 is installed in the first installation groove 4, and the first outlet The liquid pipe 11 is vertically arranged on the bottom wall of the first installation tank 4 , one end extends to the inside of the first installation tank 4 , and the other end communicates with the washing adding and dispensing mechanism 46 . The end of the first liquid outlet pipe 11 extending to the inside of the first installation groove 4 is closed, and the end is a conical structure with a smooth transition, and the side wall is provided with a first liquid outlet 10 .

Embodiment 2

[0082] like Figure 4 As shown, in this embodiment, a first liquid storage box cover 7 is provided at the first opening 45 of the first liquid storage box 1, which is matched and sealed with it. The first liquid storage box 1 and the first liquid storage box cover 7 are preferably It adopts threaded connection, which can be disassembled repeatedly, which is convenient for users to fill liquid later by themselves.

[0083] The bottom of the first liquid storage box cover 7 is provided with a through hole 13 corresponding to the first liquid outlet pipe 11, and the first sealing rubber pad 9 is arranged on the inner wall of the first liquid storage box cover 7, and the first sealing rubber pad 9 corresponds to the inner wall of the first liquid storage box cover 7. The thickness at the position of the first through hole 13 is thinner than that of other parts, and / or, the position of the first sealing rubber pad 9 corresponding to the position of the through hole 13 is set as a f...

Embodiment 3

[0085] like Figure 4 and Figure 6 As shown, the further improvement of this embodiment is that the first sealing rubber pad 9 is provided with a penetration port 32 at the bottom of the first sinker 8 corresponding to the arc-shaped protrusion, which is easy to insert the first liquid outlet pipe 11, Utilize the penetrating port 32 on the inner arc-shaped protrusion to be connected with the first liquid outlet pipe 11, wherein the first sealing rubber pad 9 has played a good sealing effect, and the laundry liquid flows into the first liquid outlet through the first liquid outlet 10. The interior of the liquid storage tank 12 is connected with the first export pipeline 26 , and the first export pipeline 26 guides the laundry liquid into the washing adding and dispensing mechanism 46 . When the first liquid storage box 1 is not installed in the first installation groove 4, the penetration opening 32 is in a naturally closed state; when the first liquid storage box 1 is taken ...

Abstract

The invention discloses an automatic feeding device for a washing machine, comprising an installation groove, a liquid storage box and a washing additive feeding mechanism connected with the installation groove. It is provided with a ventilation unit, a liquid outlet sealing unit, and the liquid outlet sealing unit is connected to the detergent additive delivery mechanism. The installation groove is provided with a pop-up unit and a locking unit. This device can ensure that the liquid in the liquid storage box flows freely in one direction and avoid dust. It falls into the liquid storage box to prevent the liquid storage box from shaking during the working process of the washing machine, and it is convenient for the liquid storage box to be taken out quickly. According to the amount of clothes, the corresponding detergent is automatically put in. The liquid storage box has a simple structure and is convenient for transportation, cleaning and replacement. , which avoids the influence of the mixing of different brands of washing liquid / or softener on laundry washing, and also reduces the possibility of the washing machine pipeline being blocked due to drying of washing additives.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to an automatic feeding device for washing machines. Background technique [0002] Now there are a variety of washing machines from various manufacturers in the market, and there are more and more functions. With the development of artificial intelligence, there are higher and higher requirements for the operation convenience and reliability of detergent injection. In terms of operation convenience, Although there have been smart washing machines on the market that store a large amount of laundry detergent at one time for multiple washing cycles, which reduces the user's operation steps to a certain extent, but users still need to go to the market to buy bags and bottles. For laundry detergents with inconsistent packaging methods, an appropriate amount of detergent is irregularly injected into the detergent storage tank, an inherent part of the washing machine. In other w...
