Embodiment 1

[0043] like figure 1 As shown, the present embodiment introduces an additive delivery device, which includes a water supply pipeline 1, and the water inlet end of the water supply pipeline 1 is communicated with the water inlet structure of the washing machine, so as to introduce the water flow into the inside of the washing machine into the delivery device; The liquid storage box 2 contains the additives used in the treatment of the clothes; the suction structure includes a connecting pipeline at least partially connected in parallel with the water supply pipeline, and the connecting pipeline is provided with a pump for providing suction power, and the liquid storage The box is connected to the connecting pipeline, and the water supply pipeline and / or the connecting pipeline are provided with a control device for controlling the flow direction and / or on-off of the liquid in the pipeline, and the additive in the liquid storage box 2 is sucked to the water supply pipeline 1, Or...

Embodiment 2

[0067] like Figure 2 to Figure 9 As shown, the present embodiment introduces an additive dispensing device, which includes a water box 100; a liquid storage box 2 for accommodating additives is installed in the water box 100; a water channel 300 is integrated on the water box 100; The top of the 300 is buckled with the upper cover 200, and the water channel 300 is integrated inside the upper cover 200 of the water box 100; further preferably, the upper cover 200 of the water box is composed of a first part and a second part that are correspondingly buckled up and down. Opposite surfaces of one part and the second part are respectively provided with opposite openings and correspondingly overlapping grooves, so that the corresponding grooves can enclose the water channel 300 after the first part and the second part are fastened to each other.

[0068] In this embodiment, the water circuit 300 of the additive injection device includes a water supply pipeline 1 for introducing th...

Embodiment 3

[0083] like Figure 2 to Figure 9 As shown, this embodiment introduces an additive dispensing device, which includes a liquid storage box 2 for accommodating additives, a water channel 300 for water intake, and a suction structure for drawing the additive in the liquid storage box 2 into the water channel 300 ; The waterway 300 is provided with a series of liquid storage chambers 3, and the liquid storage chamber 3 is provided with an opening, which is used to flow the additive pumped into the waterway 300 from the opening for temporary storage, and the additive in the liquid storage chamber 3 and the water intake Flow out after mixing.

[0084] By setting the liquid storage cavity connected in series with the water supply pipeline on the water box, the additive drawn into the water supply pipeline is mixed with the water in the water supply pipeline and then put in, so that the additives can be pre-mixed, The density of the liquid flowing to the hedging mechanism is reduced,...

Abstract

The invention discloses an additive feeding device, which comprises a liquid storage box containing the additive and a water channel for water intake; the water channel includes a first water supply pipeline and a second water supply pipeline connected with a hedging mechanism, which are used for respectively At the same time, the water enters to form multiple water inlet flows; the first water supply pipeline is connected to the liquid storage box through the suction structure, and the first water supply pipeline is provided with a liquid storage cavity, and the suction structure is used to suck the additives in the liquid storage box into the liquid storage box. In the liquid storage chamber, the water is flushed to the hedging mechanism along with the first water supply pipeline for corresponding delivery. Through the above arrangement, the water supply pipeline with the additive injection function constitutes one water inlet flow of the hedging mechanism, and the automatic injection device can use the hedging mechanism to perform corresponding injection of liquid additives. At the same time, the present invention also includes a washing machine, which is equipped with the above-mentioned additive feeding device.

Description

technical field [0001] The invention relates to a washing machine in the field of household appliances, in particular to an automatic feeding device used in the washing machine for adding additives in the process of clothes processing. Background technique [0002] Additives such as detergents, softeners, disinfectants, etc. used in the washing process of traditional washing machines are placed separately from the washing machine. There is no additive dispensing device on the washing machine, and the additives cannot be automatically dispensed. control process. With the improvement of the automation of washing machines, most washing machines are set to connect the additive box for placing detergent or / and softener with the water inlet pipeline, and flush the detergent or / and softener in the additive box into the water tub through the water inlet. However, in this structure, the detergent or / and softener must be put into the additive box every time the laundry is washed, and...
