Detergent automatic feeding device for washing machine, and control method for detergent automatic feeding device

Abstract

The invention discloses a detergent automatic feeding device for a washing machine, and a control method for the detergent automatic feeding device. The device comprises a water injection groove, a distributor box which is arranged in the water injection groove, a volume metering box which is arranged on the rear part of the water injection groove, an extraction mechanism which leads the detergent into the volume metering box, a liquid storage box and a washing water inlet which are communicated with the volume metering box, and a washing pipeline which discharges liquid in the volume metering box; the liquid storage box is arranged in the distributor box; and a distributor is arranged between the liquid storage box and the volume metering box, and when the distributor is switched off, the liquid storage box is communicated with the volume metering box, and when the distributor is switched on, the liquid storage box is not communicated with the volume metering box so as to prevent liquid from flowing back to a check valve. A main water inlet and a main water inlet pipeline are integrated on the water injection groove, the main water inlet is communicated with the distributor box through the main water inlet pipeline; a detergent feeding chamber is arranged in the distributor box; and the main water inlet pipeline is communicated with the detergent feeding chamber. The detergent is extracted in to the volume metering box by the extraction mechanism, and water flows through the washing water inlet to dilute and flush a fixed amount of the detergent into a washing barrel. The detergent automatic feeding device has the characteristics of compact structure, facilitates modularized installation and can be used conveniently by a user.

Description

technical field [0001] The invention relates to a washing machine detergent dispensing device and a control method thereof, in particular to a washing machine detergent automatic dispensing device and a control method thereof. Background technique [0002] The detergent used in the washing process of the traditional washing machine is placed separately from the washing machine. There is no detergent adding device on the washing machine, and the detergent cannot be added automatically. This structure cannot realize the automatic washing control process of the washing machine. With the improvement of washing machine automation, most washing machines are set to connect the detergent box for placing detergent or / and softener with the water inlet pipeline, and flush the detergent or / and softener in the detergent box into the washing tub through the water inlet However, this structure must first put detergent or / and softener into the detergent box every time the laundry is done, a...
