Automatic additive-feeding device and method and washing machine

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...

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.
