Problems solved by technology

[0003] But at the same time, this also brings problems. When the user does not use the washing machine for a long time, the additive will dry up and harden on the inner wall of the liquid storage box; or after multiple smart additives, some additives will harden and adhere to the pipeline and storage device of the delivery device. On the inner wall of the tank, when the user pours in new additives, the hardened additives cannot be dissolved in time, which will eventually cause difficulty in cleaning, and in serious cases will lead to blockage and invalidation of delivery.

Embodiment 1

[0050] In this example, if figure 1 As shown, there is provided an additive automatic dosing device, including a Venturi tube 7 connected to the water outlet 8, a pipeline is connected between the diffuser section 71 of the Venturi tube 7 and the water outlet 8, and a branching device is provided on the pipeline. There are flushing flow channel 1 and cleaning flow channel 2, flushing flow channel 1 is connected with additive liquid storage box 5 through water valve 6, additive liquid storage box 5 is connected with connection flow channel 3 through reversing valve 4, cleaning flow channel 2 is connected with all The above reversing valve 4 is directly connected, and the reversing valve 4 is connected with the suction port 72 of the Venturi tube 7, so that the flushing water flow and the cleaning water flow are respectively returned to the Venturi tube 7 through the reversing valve 4, and the water flow containing the additive is transported to outlet 8.

Embodiment 2

[0061] In this example, if figure 2 , as shown in 4 and 5, the present invention provides an additive automatic dosing device, including a Venturi tube 7 connected to the water outlet 8, and a pipeline is connected between the diffusion section 71 of the Venturi tube 7 and the water outlet 8, The pipeline is divided with a flushing channel 1 and a cleaning channel 2, the flushing channel 1 is connected to the reversing valve 4 through the additive liquid storage box 5, the cleaning channel 2 is directly connected to the reversing valve 4, and the reversing The valve 4 is connected to the suction port 72 of the Venturi tube 7 , so that the flushing water flow and the cleaning water flow respectively pass through the reversing valve 4 and flow back to the Venturi tube 7 , and the water flow with dissolved additives is delivered to the water outlet 8 .

[0062] In this embodiment, the suction structure is connected to the water supply structure, and the water outlet end of the s...

Embodiment 3

[0078] In this example, if image 3 As shown, one end of the flushing channel 1 is connected to the water supply channel downstream of the suction structure, and the other end is connected to the suction port of the suction structure through the liquid storage box 5. Pressure, the flushing water introduced from the flushing channel 1 in the liquid storage box 5 is returned to the water supply channel through the action of the suction structure.

[0079]In this embodiment, the suction structure is connected to the water supply structure, and the water outlet end of the suction structure branches out of the flushing channel 1 on the pipeline connected to the water outlet 8 . In the existing dispensing device, negative pressure vacuum is often used to directly suck the lotion into the waterway, and since the lotion is mostly viscous liquid, it will cause residual hardening in the liquid storage box if it is not used for a long time. To solve this problem, In the present inventio...

Abstract

The invention discloses an automatic additive-feeding device and method and a washing machine; the automatic additive-feeding device comprises: a water supply passage that may deliver water to a wateroutlet; a liquid storage box containing an additive; a suction structure that can draw out the additive in the liquid storage box and convey the additive to the water outlet along with the water flowby generating negative pressure on the water flow flowing through the water supply passage; and a flushing passage, used for controllably connecting the water supply passage with the liquid storage box, and conveying the water flow in the water supply passage to the liquid storage box for flushing. The invention also provides the washing machine with the automatic additive-feeding device, and theresidual additive dissolved in the liquid storage box through the water flow in a flushing passage is fed into a washing drum along with the water incoming flow of the washing machine, so that the liquid storage box can be conveniently and efficiently washed without waste.

Description

technical field [0001] The invention relates to the technical field of clothes processing devices, in particular to an additive automatic feeding device and method and a washing machine. Background technique [0002] With the growth of consumption level, consumers have higher requirements for the quality of daily life, so there is a demand for smart home appliances. Many washing machines currently on the market use automatic delivery systems, which can intelligently add detergent. And softener, users only need to add a large amount of detergent at one time, and then avoid the trouble of adding it every time they are used. [0003] But at the same time, this also brings problems. When the user does not use the washing machine for a long time, the additive will dry up and harden on the inner wall of the liquid storage box; or after multiple smart additives, some additives will harden and adhere to the pipeline and storage device of the delivery device. On the inner wall of th...
