Problems solved by technology

This invention solves the problem of damage to the laundry caused by the direct entry of concentrated detergent into the washing tub, but it cannot realize the precise control of automatic additives of detergent
[0005] However, after the existing automatic additive injection device is used, the additive will remain in the internal pipeline of the device, causing blockage and affecting the next use of the additive injection device; at the same time, the existing automatic additive injection device generally has a structure Problems such as complexity and too many control structures make the cost of automatic delivery devices too high and cannot be popularized

Embodiment 1

[0037] Such as figure 1 As shown, an additive dosing device is introduced in this embodiment, which includes a water supply pipeline 1, and the water inlet end of the water supply pipeline 1 is connected with the water inlet structure of the washing machine, so as to introduce the water flow introduced into the washing machine into the dosing device; The liquid storage box 2 contains the additives used when treating the clothes; the suction structure includes a connecting pipeline at least partially connected in parallel with the water supply pipeline, and a pump providing suction power is provided on the connecting pipeline, 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 of the liquid in the pipeline, and / or on-off, to suck the additive in the liquid storage box 2 to the water supply pipeline 1, Or feed water into the water supply p...

Embodiment 2

[0061] Such as Figure 2 to Figure 9 As shown, an additive feeding device is introduced in this embodiment, which includes a water box 100; a liquid storage box 2 for containing additives is installed in the water box 100; a waterway 300 is integrated on the water box 100; preferably, the waterway The top of 300 is fastened with an upper cover 200, and the waterway 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 buckled correspondingly up and down. The opposite surfaces of the first part and the second part are respectively provided with opposite openings and corresponding overlapping grooves, so that the corresponding grooves enclose the waterway 300 after the first part and the second part are fastened together.

[0062]In this embodiment, the water path 300 of the additive dosing device includes a water supply pipeline 1 for introducing water in...

Embodiment 3

[0077] Such as Figure 2 to Figure 9 As shown, an additive feeding device is introduced in this embodiment, which includes a liquid storage box 2 for containing the additive, a water channel 300 for water intake, and a suction structure for pumping the additive in the liquid storage box 2 into the water channel 300 ; The waterway 300 is provided with a liquid storage chamber 3 connected in series, and the liquid storage chamber 3 is provided with an opening for temporarily storing the additive pumped into the waterway 300 from the opening, and the additive in the liquid storage chamber 3 and the water inlet Mix and flow.

[0078] By setting the liquid storage chamber connected in series with the water supply pipeline on the water box, the additives pumped into the water supply pipeline are mixed with the incoming water in the water supply pipeline before being put in, realizing the pre-mixing of additives, The density of the liquid flowing to the hedging mechanism is reduced,...

Abstract

The invention discloses an additive feeding device which comprises a water supply pipeline; a liquid storage box in which an additive is accommodated; and a pumping structure, comprising a connectingpipeline which is at least partially connected with the water supply pipeline in parallel, a power unit for providing pumping power being arranged on the connecting pipeline, the liquid storage box being connected with the connecting pipeline, a control device for controlling a flow direction and / or on-off of liquid in the pipeline is arranged on the water supply pipeline and / or the connecting pipeline, and the pumping structure being used for pumping the additive into the water supply pipeline or flushing the power device when fed water flows through the connecting pipeline. By means of the arrangement, the automatic feeding device can achieve the effects of pumping the additive into the water supply pipeline through the pumping structure and flushing the pumping structure to be switchedfor use, the structure is simplified, and the problem of additive retention after use is solved. Meanwhile, the invention further comprises a washing machine which is provided with the additive feeding device.

Description

technical field [0001] The invention relates to a washing machine in the field of household electrical appliances, in particular to an automatic feeding device for adding additives in the process of treating clothes, which is applied to the washing machine. Background technique [0002] The additives such as detergent, softener, disinfectant, etc. used in the washing process of traditional washing machines are placed separately from the washing machine. There is no additive feeding device on the washing machine, and the additives cannot be automatically added. This structure cannot realize automatic washing of the washing machine. control process. With the improvement of washing machine automation, 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 tank through the water inlet, But this structure must first put detergent or / a...
