Abstract
An electric opener for the door of refrigerator is composed of speed-varying electric motor and friction ratchet mechanism, which are installed in a preset space in foamed layer of refrigerator casing. Said friction ratchet mechanism fixed to output axle of electric motor by pin consists of ratchet wheel, cam and roller. Said cam is connected via reset spring to fixing frame of electric motor. It has an impact block to trigger limit switch when it reaches maximum laised height, resulting in breaking off circuit and resetting cam. Its advantage is that the door of refrigerator can be smoothly and flxiblly opened without impact.
Description
The present invention relates to a kind of refrigerator (comprising household freezer and refrigerating box).Be a kind of improvement of structure of door of refrigerator specifically.
At present, on the door of the refrigerator of selling on the market or people use (comprising refrigerating chamber and refrigerating chamber), the handle of door is installed all generally, perhaps the built-in door handle that constitutes of the groove that on the door body, forms by the variation of panel or door body steel plate shape.When people will open door of refrigerator,, perhaps hand is inserted in the groove that the variation of door panel or steel plate shape forms with pulling handle.Pull at.When firmly work energetically the door sealing magnetic stripe to the absorption affinity of the steel plate of electric refrigerator housing body the time, door promptly is opened.Before the present invention generates, do not see the device record in the literature that other open door of refrigerator as yet.This door of refrigerator that handle is housed, when opening, firmly can not be just greater than the sealing magnetic stripe of door of refrigerator absorption affinity to the casing steel plate, and often overexert.Open the door in a flash at this, will make refrigerator produce shake, at this moment,, will spill or be scattered out owing to overexerting and moving all of a sudden if the plate that fills liquid or other article that easily are scattered, bowl etc. are arranged in another hand middle-end.
Purpose of the present invention, just the dried opening device that overcomes above-mentioned door of refrigerator (being door handle or the built-in door handle that produces by the panel or the steel plate deformation of door), when opening, because of producing the defective that shake is easily trickled down the article in the hand, a kind of motor drive mechanism that miniature variable-speed motor and friction ratcher are housed is provided, open the door of refrigerator, realize that not producing the soft of impact opens the door.
The present invention realizes with following technical proposals: in the casing central sill of refrigerator or giving in the chamber of leaving a blank of the foaming layer on the upper and lower beam, miniature variable-speed motor and friction ratcher are housed.The friction ratchet mechanism is fixed on the output shaft of motor by pin.The friction ratchet mechanism comprises ratchet, ratchet is with cam outward, between ratchet and cam four rollers, cam links to each other with motor retainer bracket by a back-moving spring, there is the impact block of a standing shape at the edge of cam, when cam was arrived maximum lift by Motor Drive, impact block can touch the limit switch that is fixed on the motor retainer bracket just.The control circuit switch of motor is located on the casing.During switch on pressing electromotor control circuit, power connection, miniature variable-speed motor begins rotation, the direction of rotation of output shaft is the direction rotation along the locking of ratchet notch, roller moves along the opposite direction that ratchet slot rotates, and drives the cam rotation, and cam rotates along the motor output shaft direction, behind cam contact door of refrigerator body, because of the lift of cam, gradually the door body is backed down, when reaching maximum lift, this moment impact block on cam edge, just touch the limit switch on the motor circuit that is fixed on the motor retainer bracket, motor is stopped power supply, shuts down, at this moment, the cam springs return original place that is reset.
The present invention has following good effect: owing to be provided with the electric opening device of being made up of miniature variable-speed motor and friction ratcher on electric refrigerator housing body, and the unlatching of door of refrigerator is after motor is powered rotation, the rotation of drive cam, when cam rotates to after door of refrigerator contacts, gradually along the curve of cam, up to the maximum lift that rotates to cam, i.e. Men unlatching is by the minimum lift of the cam process to maximum lift, when arriving maximum lift at last, door is backed down, this moment is by the limit switch that touches at the impact block on the cam on the electromotor control circuit, down circuitry, motor stops, and cam retracts the original place by cam returning spring, and door has been opened.In this process, do not produce impact, thereby to open the door be soft, stably, can any influence not arranged the hand-held any article of clamshell doors person.
Below in conjunction with accompanying drawing structure of the present invention is described in further detail:
Fig. 1 is the structure cross-sectional schematic of door of refrigerator opening device of the present invention.
Fig. 2 is that A-A in the structure cross-sectional schematic of electric door opener of refrigerator of the present invention is to view.
In the accompanying drawings, 1 is that miniature variable-speed motor, 12 is the variable-speed motor output shaft, and 11 is pin, 2 is ratchet, and 4 is roller, and 3 is cam, 6 is cam returning spring, 7 is miniature variable-speed motor fixed mount, and 31 is the impact block on the cam, and 8 is limit switch, 9 is the casing steel plate, 10 is motor retainer bracket, and 13 is the foam box layer, and 15 is the door of refrigerator body.On the casing central sill of refrigerator or upper and lower beam or the giving in the chamber 5 of leaving a blank of the foaming layer 13 of underbeam, miniature variable-speed motor 1 and friction ratcher are housed.The friction ratchet mechanism is fixed on the output shaft 12 of motor 1 by pin 11, the friction ratchet mechanism comprises ratchet 2, ratchet is with cam 3 outward, between ratchet 2 and cam 3 four rollers, cam 3 links to each other with motor 1 fixed mount 7 by a back-moving spring, and there is the impact block 31 of a standing shape at the edge of cam 3.When cam 3 was driven into maximum lift by motor 1, impact block 31 can touch the limit switch 8 that is fixed on the motor retainer bracket 7 just.The control circuit switch of motor 1 is located on the casing.During switch on pressing motor 1 control circuit, power connection, miniature variable-speed motor begins rotation, the direction of rotation of output shaft 12 is the direction rotations along the locking of ratchet 2 notches, roller 4 moves along the opposite direction that ratchet slot rotates, drive cam 3 rotations, cam 3 is along the rotation of motor output shaft 12 directions, behind cam 3 contact door of refrigerator bodies 15, lift because of cam 3, gradually the door body is backed down, this moment, the collision block 31 on cam edge touched the motor circuit upper limit position switch 8 that is fixed on the motor retainer bracket 7 just, motor 1 is stopped power supply, shut down, at this moment, cam 3 spring 6 that is reset retracts the original place.
