Title:
DOOR OPENING ASSISTING MEANS AND REFRIGERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/201843
Kind Code:
A1
Abstract:
A door opening assisting means (30) and a refrigerating device (1). The refrigerating device (1) comprises a cabinet body (10) provided with the door opening assisting means (30) and a door body (20) connected to the cabinet body (10). The door opening assisting means (30) comprises: an ejecting structure (302), which comprises a transmission pinion (3022) and a rack (3024) matching the transmission pinion (3022), the transmission pinion (3022) being partially provided with gear teeth (30222); an elastic member (304), which is separately connected to the cabinet body (10) and the rack (3024); and a drive means (306), which is connected to the transmission pinion (3022) and drives the transmission pinion (3022) to rotate. When the transmission pinion (3022) rotates till the gear teeth (30222) are engaged with the rack (3024), the transmission pinion (3022) drives the rack (3024) to move in a direction towards the door body (20) to make the rack (3024) abut against the door body (20), thereby pushing the door body (20) open from the cabinet body (10). When the transmission pinion (3022) rotates till the gear teeth (30222) are disengaged from the rack (3024), the rack (3024) is restored to an initial position under the tension force of the elastic member (304). The drive means (306) and the ejecting structure (302) work in concert to complete ejection of the rack (3024) of the ejecting structure (302), so that the door body (20) can be pushed open from the cabinet body (10), thereby assisting in opening a door.
