Problems solved by technology

[0003] This patented technology can easily switch between automatic and manual door opening modes, but its large structure is not suitable for small spaces, especially when it is in an automatic program, if there is a sudden power failure, or when the manual is changed to automatic, when the nut and the lead screw are re-engaged , the teeth may not be just meshed, and sometimes they will be misaligned. At this time, the motor will rotate forcibly, which will damage the teeth on the nut and / or screw, and affect the service life of the entire transmission mechanism.

Abstract

The invention relates to a drawer opening mechanism. The drawer opening mechanism is arranged between a cabinet body (1) of a disinfection cabinet and a drawer (2). The drawer opening mechanism is characterized in that a guide rod (3) and a rack (52) are located relative to the side walls of the cabinet body (1) and arranged in the pulling direction of the drawer (2); a sliding table (4) is in driving connection with the drawer (2) can be limited on the guide rod (3) in a sliding manner; the rack (52) and the guide rod (3) are arranged at intervals in an up-down manner; a clutch mechanism (6)is used for driving the rack (52) to move up and down, so that the rack is meshed with or de-meshed from a gear (51); a motor (53) is in driving connection with the sliding table (4); and an output shaft of the motor (53) is in driving connection with the gear (51). A manual mode and an automatic mode of the drawer opening mechanism can be freely switched; and the drawer opening mechanism is compact in structure and can be installed in a narrow and small space.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a drawer opening mechanism for household appliances. Background technique [0002] CN201110190394.8 discloses "A Screw Drive Storage Door Drive Device Switchable to Automatic or Manual Mode". The box is connected to the screw, and the electromagnetic suction device set on the sliding block controls the pressing or rising of the electromagnetic suction pressure rod. A spring is arranged at the bottom, and a sliding block matching with the leading screw clearance is also arranged on the sliding box, so that the door body of the warehouse door drives the transmission box to slide on the leading screw through the connecting rod. [0003] This patented technology can easily switch between automatic and manual door opening modes, but its structure is huge and is not suitable for small spaces, especially when it is in the automatic program, if there is a sudden power failure, or whe...
