Problems solved by technology

[0003] Generally, the observation window of the washing machine needs to be opened manually by the user. In order to facilitate the user to open the door, a certain space must be reserved as a door handle for the user to open the door. This design will make the observation window protrude, which increases the depth of the machine. The plane design of the surface is difficult to realize. During the packaging and transportation process, the outwardly protruding observation window made of plastic material is also easy to be damaged by collision and cause loss.
[0004] In addition, after the washing machine has finished washing, the observation window cannot be opened automatically. If the user cannot take out the washed clothes in time, the observation window will remain closed, and the washed clothes will be placed in the wet drum for a long time, which is extremely dangerous. It is easy to breed bacteria and odors. Clothes contaminated with bacteria will cause discomfort to users after wearing them. To remove odors and bacteria, users need to re-wash, wasting time and energy

Embodiment 1

[0057] Such as Figure 1-8 As shown, the present embodiment provides a drum washing machine, which includes a body front plate 1 and an observation window door 2. The body front plate 1 is provided with an inwardly recessed installation space 3, and the installation space 3 is provided with a clothing insertion port 4 for viewing. The window door 2 is embedded in the installation space 3 and is connected with the machine body front plate 1 through a hinge 7 to open / close the clothes delivery port 4; the observation window door 2 and the machine body front plate 1 form a flat front surface of the washing machine.

[0058] The body front panel 1 of the drum washing machine in this embodiment is provided with an inwardly recessed profile to form an installation space 3 for the observation window and door 2 . The observation window door 2 is completely embedded in the installation space 3 and can be rotated open, that is, the observation window door 2 is embedded in the front pane...

Embodiment 2

[0072] Such as Figure 8-9 As shown, this embodiment is a further limitation of Embodiment 1. In this embodiment, the observation window door 2 is provided with a door hook 9 on the side facing the annular groove 5, and the annular groove 5 is provided with a door lock that cooperates with the door hook 9. 10. The door lock 10 cooperates with the door hook 9 to lock or open the observation window 2 . Wherein, the door lock 10 can be a mechanical self-jacking door lock 10 , or an electromagnetic self-jacking door lock 10 .

[0073] Specifically, a door lock 10 is provided in the annular groove 5 on the opposite side of the hinge installation area 6, and a door hook 9 is provided at the corresponding position of the observation window door 2 facing the annular groove 5; the washing machine control When the door lock 10 was opened automatically, the door lock 10 flicked open the observation window door 2, and the observation window door 2 opened a certain angle.

[0074] The do...

Embodiment 3

[0097] This embodiment is a further limitation of Embodiment 1. The difference between this embodiment and Embodiment 2 is that: the observation window door 2 of this embodiment is provided with a door hook 9 toward the side of the annular groove 5, and a door hook 9 is provided in the annular groove 5. There is a door lock 10 matched with the door hook 9. There is a certain displacement space 11 for the door hook 9 between the observation window door 2 and the bottom wall of the annular groove 5. When the observation window door 2 is pushed, Door lock 10 bounces observation window door 2.

[0098] The door lock 10 of the present embodiment is a mechanical self-ejecting door lock 10. When the user needs to open the door, the user can press the observation window door inwardly, and the door hook 9 will bounce inward after a certain stroke, and the observation window door will be opened. This method can facilitate the user to open the door, reduce the door opening force, and imp...

Abstract

The invention discloses a drum washing machine. The drum washing machine comprises a machine body front panel and an observation window door, a mounting space which is sunken inwards is arranged on the machine body front panel, a clothes putting port is formed in the mounting space, and the observation window door is embedded in the mounting space and connected with the machine body front panel through hinges to open / close the clothes putting port; the observation window door and the machine body front panel form a flat front surface of the washing machine. According to the drum washing machine, the observation window door is designed to be embedded, the observation window door and the machine body front panel form integrated design appearance, the occupied space can be reduced, and the attractiveness of the whole machine is improved; meanwhile, in the conveying and using process, the outer damage and replacement frequency of the observation window can be reduced, and the economical efficiency is improved. Besides, after the clothes washing process is finished, the observation window door can be automatically jacked open, and a humid closed space is opened, which helps to reduce peculiar smell of clothes and breeding of bacteria.

Description

technical field [0001] The invention belongs to the field of drum washing machines, and in particular relates to a drum washing machine and a control method. Background technique [0002] In the existing drum washing machine, an observation window is provided at the clothes inlet of the washing machine, and the observation window is connected with the front plate of the washing machine through a hinge, which not only plays a role of sealing the washing machine to prevent the water in the drum from overflowing, but also facilitates the user to clean the washing machine at any time. Observe the laundry condition in the tub. [0003] Generally, the observation window of the washing machine needs to be opened manually by the user. In order to facilitate the user to open the door, a certain space must be reserved as a door handle for the user to open the door. This design will make the observation window protrude, which increases the depth of the machine. The planar design of th...
