Description

Drum washing machine and washing method

Technical field

The invention relates to the field of washing machines, in particular to a drum washing machine and a washing method.

Background technique

At present, most of the detergent storage and dispensing devices of the drum washing machine that automatically dispenses detergent are located in the upper corner of the washing machine. When the detergent is put on, a certain amount of detergent is flushed into the washing outer cylinder by tap water. The unfavorable result is that the detergent and the water are not uniformly mixed, and the washing water containing the high-concentration detergent first flows to the bottom area of the washing outer cylinder, and cannot directly contact the laundry and the stain on the clothes; When the water level in the washing outer cylinder rises to a higher position and the washing inner cylinder is stirred for a set time, the detergent can be evenly distributed into the washing water, and then the laundry is contacted, so that the detergent utilization efficiency is low. The washing effect is not good.

In addition, in order to accommodate the narrow space in the upper corner of the drum washing machine, the detergent storage boxes of these washing machines are generally elongated and extend in the longitudinal direction of the washing machine. This makes it difficult for the user to check the remaining amount of the detergent in the storage box, and is also disadvantageous for the user to add the detergent in time.

The door body of the drum washing machine is generally fixed with a glass bowl by the door frame. When the door body is closed, the edge of the protruding portion of the glass bowl is in close contact with the sealing ring of the washing nozzle, so as to achieve the sealing and washing of the outer tube. The purpose of the mouth. The internal space of the projection of the glass bowl is not utilized, which causes a certain waste of space.

For example, the application number is 201310151812.1, "washing machine"; the washing machine comprises: a casing; a dispenser; a door body, the door body comprises a door front cover, a door back cover and a door glass, the door front cover and the door back cover Connected and forming an installation space; a detergent expansion storage space, the detergent expansion storage space is disposed in the installation space; and a pumping device, the pumping device is disposed on the casing, the pumping device A separate connection to the dispenser and the detergent expansion storage space to pump liquid in the detergent expansion storage space to the dispenser.
