Description
Technical Field
the invention relates to washing machine equipment in household appliances, in particular to a top-opening type drum washing machine, in particular to a drum washing machine, wherein a drum is composed of an inner drum without dewatering holes and provided with a clothes throwing opening at the top.
Background
Washing machines are largely classified into pulsator type, pulsator type and drum type washing machines. Generally, a washing machine removes stains from laundry by the action of water and detergent.
The pulsator type washing machine performs a washing operation by rotating a pulsator at the center of a washing tub left and right. The agitator type washing machine performs a washing operation using a frictional force between water current and laundry by rotating a rotary blade at the center of a washing tub in the left-right direction. The drum type washing machine performs a washing operation by beating laundry by rotating a drum.
A drum type washing machine generally includes a housing, an outer tub for containing washing water therein, a drum for containing laundry therein, and a motor and a shaft for rotating the drum on a rear surface of the outer tub.
in addition, there are a control part for controlling the washing process, generally a control panel, and a water inlet and discharge mechanism, etc. The drum type washing machine removes stains contained in laundry using frictional force between wash water stored in a sump and the laundry in a drum and chemical action of detergent contained in the wash water.
The washing drum is used as an important part of the washing machine, is not only used for accommodating washings to form a washing container, but also can participate in washing work, particularly the drum washing machine mainly depends on the rotation action of the washing drum to lift and throw off the clothes to form a beating effect, and meanwhile, the washing drum also has a certain rubbing action on the clothes, so that the washing effect is realized by beating and washing; besides pulsator washing, many of the existing pulsator washing machines also adopt a washing drum to wash, for example, so-called "dual-power" washing machines which are popular in the market.
Compared with the pulsator washing machine, the drum washing machine has the weak point that the door is arranged at the front side, so that after water enters, the door is inconvenient to open, clothes are added again, and clothes are contained or taken out, and people need to bend down or squat down to take the clothes, which is very inconvenient for old people or pregnant women. Therefore, the top-opening type drum washing machine has the advantages that the drum washing machine is clean in washing and small in abrasion, and the rotary drum washing machine is provided with an upper opening for taking and placing clothes and can add the clothes midway.
The present invention has been made in view of this situation.
