Abstract
The present invention relates to an electric opener for a door of a refrigerator, which is composed of a variable speed motor (1) and a friction ratchet which are arranged in a prearranged cavity of a foaming layer of a refrigerator body of the refrigerator, wherein the friction ratchet is fixed on an output shaft (12) of a motor (1) through a pin cylinder (11); the friction ratchet comprises a ratchet wheel (2), a cam (3) and a pin roller (4), wherein the cam (3) is connected with a fixed frame (7) of the motor through a reset spring (6); an impact block (31) is arranged on the cam (3). When the cam (3) reaches a maximum lift range, the impact block (31) touches a limit switch (8), a circuit is cut off, and the cam (3) resets. When provided with the present invention, the door of the refrigerator has no impact when opened, the door is opened softly and stably, and articles held in hands of operators can not be influenced.
Description
The present invention relates to a kind of refrigerator (comprising household freezer and refrigerating box), is 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, pulls at pulling handle, when used power greater than 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 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 be to overcome the opening device (being door handle or the built-in door handle that produces by the panel of door or steel plate deformation) of above-mentioned door of refrigerator, 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: a kind of refrigerator, constitute by electric refrigerator housing body and door of refrigerator body, it also is equipped with electric door opener of refrigerator, said electric door opener of refrigerator is in the reservation cavity by foaming layer on electric refrigerator housing body miniature variable-speed motor and friction ratcher to be housed, said friction ratcher is fixed on the output shaft of miniature variable-speed motor by pin, the control circuit switch of miniature variable-speed motor is located on the electric refrigerator housing body, said friction ratcher 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.
In technique scheme, said miniature variable-speed motor can be contained on refrigerator central sill, upper beam or the underbeam.
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, the rotation of drive cam, cam are along the rotation of motor output shaft direction, behind cam contact door of refrigerator body, lift because 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, shut down, 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 electric door opener of refrigerator 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 miniature variable-speed motor, and 12 is the variable-speed motor output shaft, 11 is pin, and 2 is ratchet, and 4 is roller, 3 is cam, and 6 is cam returning spring, and 7 is miniature variable-speed motor fixed mount, 31 is the impact block on the cam, 8 is limit switch, and 9 is the casing steel plate, and 10 is motor retainer bracket, 13 is the foam box layer, and 15 is the door of refrigerator body.
A kind of refrigerator, constitute by electric refrigerator housing body and door of refrigerator body, it also is equipped with electric door opener of refrigerator, said electric door opener of refrigerator is in the reservation cavity by foaming layer on electric refrigerator housing body (5) miniature variable-speed motor (1) and friction ratcher to be housed, said friction ratcher is fixed on the output shaft (12) of miniature variable-speed motor (1) by pin (11), the control circuit switch of miniature variable-speed motor (1) is located on the electric refrigerator housing body, said friction ratcher comprises ratchet (2), the outer cam (3) that is with of ratchet (2), between ratchet (2) and cam (3), be four rollers (4), cam links to each other with motor retainer bracket (7) by a back-moving spring (6), there is the impact block (31) of a standing shape at the edge of cam (3), when cam was arrived maximum lift by Motor Drive, impact block (31) can touch the limit switch (8) that is fixed on the motor retainer bracket (7) just.
In technique scheme, said miniature variable-speed motor (1) can be contained on refrigerator central sill, upper beam or the underbeam.
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 rotation along the locking of ratchet (2) notch, roller (4) moves along the opposite direction that ratchet slot rotates, drive cam (3) rotation, cam (3) rotates along motor output shaft (12) direction, behind cam (3) contact door of refrigerator body (15), lift because of cam (3), gradually the door body is backed down, when reaching maximum lift, this moment impact block (31) on cam edge, just touch the limit switch (8) on the motor circuit that is fixed on the motor retainer bracket (7), motor (1) is stopped power supply, shuts down, and cam this moment (3) spring (6) that is reset retracts the original place.
