Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 to Figure 3 As shown, the detergent delivery box of the drum washing machine of the present invention includes a washing solution box 2 containing laundry detergent, softener or disinfectant, a lower water box 1 and an automatic delivery pump 6, and the top of the washing solution box 2 is provided with an internal Pipeline, the liquid inlet 10 of the internal pipeline is connected with the automatic feeding pump 6 through the check valve 7, the internal pipeline draws liquid from the bottom of the washing liquid box, the automatic feeding pump 6 is installed on the lower water box 1, and the automatic feeding pump 6 is preferred It is a piston pump with high self-priming capacity. The automatic delivery pump 6 injects detergent into the shower assembly 3 located on the top of the drain box 1 through the infusion tube 9. The shower assembly 3 i...

Abstract

The invention discloses a washing-agent putting box of a roller washing machine. The washing-agent putting box comprises a washing liquid box, a water discharging box, a shower assembly and an automatic putting pump. A liquid inlet is formed in the top of the washing liquid box and connected with the automatic putting pump through a one-way valve, the automatic putting pump is located on the washing liquid box, and puts washing agents into the shower assembly through a liquid conveying pipe. According to the washing-agent putting box of the roller washing machine, the automatic putting pump is arranged at the top of the washing liquid box, the high liquid-inlet mode and the high liquid-outlet mode are adopted, and it is avoided that the large quantity of washing agents are leaked when a drawer box of the washing machine is drawn out; as the putting time of washing liquid of the washing machine is shorter than the water flushing time of the washing machine, after the washing agents are added into the washing machine, water flushing is further continuous, residual washing agents in a washing-agent washing pipe are flushed away through water, and when a water inlet is stopped to conduct water flushing, the liquid conveying pipe reabsorbs part of water in a pump-washing-agent liquid inlet through the negative pressure effect, and it is avoided that the liquid inlet is dried up and plugged.

Description

technical field [0001] The invention relates to a detergent delivery box for a drum washing machine, which belongs to the field of washing machines. Background technique [0002] In the existing detergent automatic dispensing system, due to the poor self-priming performance of the pump, the pump installation method adopts the traditional dispensing method of low liquid intake and high liquid discharge, so that a cavity for storing liquid must be designed in the dispensing system. During the extraction process of the drawer box, the storage cavity must be equipped with a valve device to prevent the liquid from leaking out of the storage cavity. When the washer liquid box and the drain box are separated, part of the detergent will leak out. In addition, this situation will cause the pipeline to be too long, and there is a risk of pipeline blockage. Because there is a liquid storage chamber and a one-way valve device, the product cost is too high. Contents of the invention ...
