Feeding device for washing machine and washing machine

Abstract

The invention relates to a feeding device for a washing machine. The feeding device includes a driving unit which is used for transmitting main power to driven units and driving the driven unit to move; the plurality of driven units used for receiving the main power transmitted by the driving unit; a plurality of feeding pumps connected with the corresponding driven units correspondingly, receiving the main power transmitted by the driven units and used for feeding liquid detergent; a switching unit used for switching connection states of the driving unit and the plurality of driven units, thereby achieving automatic switching, correspondingly, parts of the feeding device are simplified, driving units of the plurality of feeding devices are not needed, feeding of a plurality of kinds of liquid detergent can be completed only through one driving unit, and thus the structure is simple. Meanwhile, the invention further relates to a washing machine using the feeding device.

Description

technical field [0001] The invention relates to the technical field of feeding for washing machines, in particular to a feeding device for washing machines and the washing machine. Background technique [0002] At present, washing machines mostly use a variety of detergents such as laundry detergent, softener or disinfectant, and for the convenience of adding detergents, they are all equipped with automatic feeding systems. [0003] The automatic feeding system of the existing washing machine is generally equipped with multiple sets of pump liquid devices for extracting detergent from different storage boxes. Put it into the laundry bucket, so that multiple sets of pumping systems are required and each has its own pumping structure, corresponding to multiple motors; on the other hand, in a system where one motor controls multiple pump structures, positive and negative Rotation control is only applicable to two pump liquid devices, and when three or more detergents need to b...

[0003] The automatic feeding system of the existing washing machine is generally equipped with multiple sets of pump liquid devices for extracting detergent from different storage boxes. Put it into the laundry bucket, so that multiple sets of pumping systems are required and each has its own pumping structure, corresponding to multiple motors; on the other hand, in a system where one motor controls multiple pump structures, positive and negative Rotation control is only suitable for two pump liquid devices. When three or more detergents need to be used, it cannot really realize that one motor controls multiple pumps to dispense detergent separately.
