Description

Drum washing machine

Technical Field

The invention belongs to the field of household appliances, and particularly relates to a drum washing machine.

Background

The drum washing machine originates from Europe, the washing method is designed by simulating the principle that a hammer strikes clothes, the clothes are lifted to the high position of a drum and fall to the water surface under the action of gravity to flap with the water surface, and therefore the clothes are washed. The drum washing machine consists of stainless steel inner drum, mechanical program controller, casing with three protections of phosphorization, electrophoresis and spraying, and several heavy cement blocks for balancing the repeated motion of the great centrifugal force produced during the rotation of the drum and washing with washing powder and water. At present, most of the drum washing machines in the market use independently designed material boxes to put washing powder, and the design not only makes the structure of the drum washing machine complicated, but also causes the production cycle to be prolonged due to excessive quantity of components, and is not beneficial to the maintenance of the drum washing machine; moreover, consumers cannot visually see the amount of the washing powder put in the feeding box, the amount of the washing powder put in the feeding box is too much or too little, and the washing effect cannot be guaranteed; in addition, the washing powder box which is designed independently can damage the washed articles, and a plurality of washing foams can remain on the door glass of the drum washing machine after washing is finished, so that people can feel unclean.

Chinese patent with application number CN201510123069.8 discloses a drum washing machine, wherein a door glass is fixed in the front door of the drum washing machine through a door seal, the door glass is provided with a cavity for storing detergent and having an opening at the top, the bottom of the cavity is at least provided with a discharge port for discharging the detergent to the washing tub of the drum washing machine, a discharge component for putting the detergent is arranged in the cavity at the discharge port, the water inlet end of a water inlet pipe is communicated with the water inlet component of the drum washing machine, the water outlet end is communicated with the cavity, and the water guide port of the water outlet end is opposite to the discharge component in a staggered manner; meanwhile, the washing method of the drum washing machine is also involved.

With the progress of the technology, the existing washing machine has the function of automatically putting detergent in sequence, detergent and softener which can be washed for many times are poured into a detergent distributor box once, the detergent and the softener can be automatically added according to needs in the process of washing for many times, and the detergent in a detergent storage container is put into a washing barrel by using a putting pump to participate in washing. However, the purchased detergent is often required to be added into the dispenser, the use of the detergent is troublesome for consumers due to different sizes of the bottles and the cans, and the residual amount of the detergent cannot be observed in time in the washing process; meanwhile, the detergent box of the drum washing machine occupies the upper part of the washing machine, is not coordinated with the operation panel, is not beautiful, is inconvenient for consumers to use, and occupies a large space of the washing machine.

Therefore, in order to solve the above problems, it is necessary to improve the deficiencies and drawbacks of the prior art, and provide a washing machine that makes full use of the empty structural space of the sealed glass door and window of the prior washing machine, and arranges a detergent feeding box, a softener feeding box, etc., so as to eliminate the detergent box at the upper part of the washing machine, realize the integration of the operation panel, and is no longer arranged with the detergent box; the appearance of the washing machine is greatly improved, the detergent is convenient and quick to replace and simple to operate, and the unused space in the past is just utilized; after the washing is finished, the glass door is kept clean, and the consumer experience is greatly improved.
