Description

TECHNICAL FIELD

[0001] The disclosure belongs to the field of household appliances, and particularly relates to a drum washing machine.

BACKGROUND

[0002] Drum washing machines originated from Europe, a washing method of which is designed by imitating dollies beating clothes, that is, the clothes are lifted to a high position of a drum and fall to the water surface under gravity, and then the clothes are beaten by water so as to be cleaned. The drum washing machine consists of a stainless steel inner drum, a mechanical program controller, a housing which is protected through phosphating, electrophoresis and spraying, and a plurality of heavy cement blocks which are used for balancing the huge centrifugal force generated when the drum rotates. And the combined action of repeated movements of the inner drum, detergent and water, makes the clothes clean. At present, most drum washing machines in the market use individually designed feeding boxes to put detergent. Such a design, on the one hand, complicates the structure of the drum washing machines, making the number of parts too large, resulting in prolonged production cycle, and is not conducive to the maintenance of the drum washing machines in the future. On the other hand, consumers can not directly see the amount of the detergent put in the feeding boxes, making the amount of the detergent either too large or too small, and the washing effect is not guaranteed; and in addition, the individually designed detergent feeding boxes can cause damage to the articles to be washed, and after washing, a lot of washing foam may remain on door glass of the drum washing machines, which makes the washing machines look unclean.

[0003] The Chinese patent with an application number of CN201510123069.8 discloses a drum washing machine, a door glass of which is fixed in a front door of the drum washing machine through a door seal. The door glass is provided with a chamber used for storing detergent and having an opening in the top. The bottom of the chamber is provided with at least one discharge port used for discharging the detergent to a washing drum of the drum washing machine. A discharge component used for discharging the detergent is arranged at the discharge port in the chamber. A water inlet end of a water inlet pipe is communicated with a water inlet component of the drum washing machine, a water outlet end is communicated with the chamber. And a water guide port of the water outlet end and the discharge component are opposite in a staggered mode; and meanwhile, the disclosure also relates to a washing method of the drum washing machine.

[0004] With the progress of technology, the existing washing machines start to have the automatic detergent adding function; that is, detergent and softener which can be used for many times of washing are poured into a detergent dispenser box at one time, and then is automatically added as needed during each time of washing. And the detergent in the detergent storage container is put into a washing drum through a feeding pump to participate in washing. However, since detergent packaged bought in containers with different sizes needs to be added to the dispenser, a lot of trouble may be caused to consumers. Besides, the amount of detergent left can not be observed in time in the washing process. Moreover, an additive chamber of the drum washing machine occupies the upper part of the washing machine, which is not only incongruous with an operation panel, affecting the attractiveness of the washing machine, but also is inconvenient for the consumers to use because it occupies a large space of the washing machine.

[0005] Therefore, in order to solve the above-mentioned problems, it is necessary to improve the deficiencies and defects of the prior art. The disclosure provides a washing machine which makes full use of the vacant structural space of a sealed glass door and window of an existing washing machine by providing a detergent feeding box, a softener feeding box and the like, so that an additive chamber at the upper part of the washing machine is canceled, the integration of an operation panel is realized, and side-by-side arrangement of the operation panel and the additive chamber is avoided. In this way, the attractiveness of the washing machine is greatly improved, detergent replacement can be achieved conveniently and quickly, operation is easy, and the former vacant space is well utilized; and after washing, a glass door remains clean, greatly improving consumer experience.

[0006] In view of this, the present disclosure is proposed.

[0058] Besides, the top of the additive chamber 7 is provided with a filling port 9 which allows liquid to be fed conveniently, and the filling port 9 is provided with a sealing cover 10 for preventing the liquid from flowing out. The arrangement of the filling port 9 enables the consumers to add the detergent to the additive chamber 7 more conveniently and quickly, which improves the washing efficiency and enhances consumer experience as well. The sealing cover 10 is used for opening and closing the filling port 9 of the additive chamber 7, and ensures that the detergent in the additive chamber 7 does not flow to the outside along with the shaking or vibration of the additive chamber 7 when the consumers move or install the additive chamber 7 and during the operation of the drum washing machine.

[0059] The additive chamber 7 in the present embodiment is a detergent storage box 701 and a softener storage box 702 for containing the detergent and softener respectively. When a consumer is ready to use the washing machine to wash clothes, the detergent and softener prepared in advance are put into the detergent storage box 701 and the softener storage box 702 respectively through the filling port 9 first, and the sealing cover 10 is closed. And then, a power key 31 (not shown in the drawings) and a control knob 32 (not shown in the drawings) provided on a control panel 19 are activated to start the washing program of the washing machine. It is worth noting that the door body 3 of the washing machine can be in an open state or a closed state in this process. The adding of the detergent into the additive chamber 7 of the present disclosure can be achieved from the outside.

[0060] When the additive chamber 7 needs to be replaced or the consumer feels it is inconvenient to add the detergent, the additive chamber 7 can be taken out from the concave space 6 in the door body 3 through a box handle 11 arranged at the top of the additive chamber 7.
