TECHNICAL FIELD

The present invention relates to washing machine equipment of household appliances, in particular to a top-openable drum washing machine, in particular to a drum washing machine with a drum composed of an inner drum without dehydration holes and a port for feeding laundry formed in the top.

BACKGROUND

Washing machines can be typically divided into pulsator washing machines, agitator washing machines and drum washing machines. Generally speaking, washing machines remove stains from laundry through the action of water and detergents.
A pulsator washing machine performs washing operations by rotating a pulsator in the center of a washing tub clockwise and counter-clockwise. An agitator washing machine performs washing operations through friction between water flow and laundry by rotating a rotating fin in the center of a washing tub clockwise and counter-clockwise. A drum washing machine performs washing operations by rotating a drum to tumble the laundry.
A drum washing machine is generally provided with an outer shell, an outer tub installed inside for accommodating washing water, and a drum arranged in the interior of the outer tub for accommodating the laundry. A motor and a shaft which are used for rotating the drum are arranged on the back of the outer tub.
In addition, a control unit which is used for controlling the washing process and usually is a control panel, a water inlet mechanism, a drainage mechanism and other parts are further arranged. A drum washing machine removes stains contained in the laundry through friction between the washing water stored in a water tank and laundry in the drum, and the chemical action of the detergents contained in the washing water.
As an important part of a washing machine, a washing drum is not only used to hold the laundry and constitute a washing container, but also participate in the washing operations. Especially a drum washing machine mainly relies on the rotation of a washing drum to lift and drop the laundry to achieve an tumble effect, and meanwhile, the washing drum also has a certain rubbing effect on the laundry, so that the washing effect is achieved through tumble and washing. In addition to pulsator washing, many existing pulsator washing machines may also adopt washing drums for washing, such as so-called "dual power" washing machines popular on the market.
Compared with the pulsator washing machine, the defect of the drum washing machine is that, since the machine door is arranged on the front side, it is inconvenient to open the machine door to add laundry again after water input, and users must bend down or squat down to take out the laundry during laundry putting and taking,, which is inconvenient for the elderly or pregnant women. As a result, a top-openable drum washing machine has been invented and combines the advantages of the drum washing machine with high washing cleanliness and less abrasion of and the pulsator washing machine with the convenience of laundry taking and putting and laundry adding during the operation via the opening in the top
In view of this, the present invention is provided.
