Problems solved by technology

[0003] However, traditional electric door-opening refrigerators generally convert the driving force of the drive motor into the driving force of the refrigerator door through multiple sets of transmission components. The meshing between them is unstable or the meshing process is dislocated and stuck, which affects the service life of the electric door opener
In addition, multiple sets of transmission components will generate a lot of noise during the transmission process

Embodiment 1

[0034] Such as Figure 2-4 As shown, an automatic door opening device 100 is used for automatically opening the door of a home appliance. The automatic door opening device is used for automatically opening the door of a home appliance, such as a refrigerator, a washing machine, and a microwave oven. In an embodiment, the household appliance is specifically a refrigerator. The automatic door opening device 100 includes a base 12 fixed on the upper end 201 of the refrigerator 200 ; the base 12 is arranged at any position on the upper end 201 of the refrigerator. Preferably, it is arranged in the middle of the upper end 201 of the refrigerator. The push piece is used to push open the door body 202 of the refrigerator.

[0035] The driving part 2 is a low-speed motor in one embodiment in order to ensure that the driving part has a large output torque, a low rotational speed, a stable operation, and a small volume and weight. The low-speed motor includes a motor body and an outp...

Embodiment 2

[0044] Such as figure 1 As shown, the automatic door opening device 100 includes a base 12 and a housing 11 that is engaged with the base. An installation space is formed between the base 12 and the housing 11, and the driving member 2 and the transmission member 3 are fixed in the installation space. At least two pairs of fixing ears 131 are provided on the side edge of the housing. The fixing ears are arranged in a direction perpendicular to the casing 11 and parallel to the upper end 201 of the refrigerator. In one embodiment, the fixing ear is hollow U-shaped. The fixing ears are scattered around the outer casing 11 and fixed to the upper end 201 of the refrigerator box through fixing pieces. The fixing member is a fixing part corresponding to a fixing method common to those skilled in the art such as screws. The housing 11 is also provided with a number of positioning holes for positioning and installation. A through hole is formed on the casing 11 for the pusher to ...

Embodiment 3

[0046] Such as Figure 5 As shown, a household appliance is a refrigerator 200 in one embodiment. The refrigerator 200 includes a box body for forming a closed space in the refrigerator and a door body arranged on the front side of the refrigerator. The upper end of the box body is the upper end 201 of the refrigerator, and the box body has a door body, namely a refrigerator door body 202, which is arranged on the front side of the box body for opening or closing. The box body includes an automatic door opening device as described above, which is used to open the door body that is attracted to the box body.

[0047] One end of the pusher of an automatic door opening device 100 corresponds to the door body on one side of the refrigerator. When the refrigerator is a single-door refrigerator, one end of the pusher of the automatic door opener 100 is used to abut and open a door that is attracted to the box, that is, the end of the pusher corresponds to the door of the refrigerat...

Abstract

The invention relates to an automatic door opening device. The device comprises a base, a pushing piece, a transmission piece and a driving piece, wherein the transmission piece comprises at least one rack and a gear meshing with the rack, and the gear drives the rack to move towards a door body of a household appliance under the action of driving force and pushes the door body of the household appliance open by means of the pushing piece. The invention further relates to a refrigerator comprising the device. According to the automatic door opening device, the gear and the rack serve as the transmission piece, and the problems that in the prior art, in a transmission process of a plurality of sets of transmission wheels, stability is poor, noise is large, and occupied space is large are solved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an automatic door opening device and a refrigerator. Background technique [0002] With the improvement of living standards, smart home appliances are increasingly favored and recognized by the market. At present, users tend to prefer refrigerators with larger volumes, but the door seals of refrigerators with larger volumes also have greater suction, and an automatic door opening device is needed to improve user experience. [0003] However, traditional electric door-opening refrigerators generally convert the driving force of the drive motor into the driving force of the refrigerator door through multiple sets of transmission components. The meshing between them is unstable or the meshing process is dislocated and stuck, which affects the service life of the electric door opener. In addition, during the transmission process of multiple sets of trans...
