Abstract

The utility model relates to an electromagnetic opener for refrigerator door including an electromagnet (1), back-moving springs (4) and bumpers (2) on the box body of the refrigerator, and striking plates (3) fixed on the door body of the refrigerator. The tail section of an electro-magnetism armature (7) is able to slide in an electromagnet sleeve (14). After energizing, magnetic field is formed by coils (8) to push the electro-magnetism armature (7) to extend outwardly, the force is transmitted to the striking plates (3) fixed on the door body by rubber pads (17) on the electro-magnetism armature (7), and the striking plates (3) fixed on the door body obtains the force; in this way, the door is opened. The electromagnetic opener for refrigerator door can open the door of the refrigerator by just pressing the depressed button with no shaking and no effects on the stability of articles in the other hand.

Description

Door of refrigerator electromagnetism opening device

The utility model 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 exert oneself greater than the absorption affinity of door sealing magnetic stripe to the steel plate of electric refrigerator housing body, promptly be opened.Before the utility model designed, it was on the books in the literature not see other devices of opening door of refrigerator as yet.This door of refrigerator that handle is housed when opening, firmly can not adsorb the power of refrigerator steel casing just, and often overexert greater than the sealing magnetic stripe of door of refrigerator.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.

The purpose of this utility model, 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, the door of refrigerator that provides a kind of calutron to start is realized opening the door steadily.

The utility model is realized with following technical proposals: the casing central sill of refrigerator or on, giving in the chamber of leaving a blank of foaming layer on the underbeam, electromagnet is housed, back-moving spring, on casing, leave perforate, front end at electromagnet, at tapping, cushion rubber bumper is housed, electromagnet is by electromagnet armature, and is fixed on the electromagnet bonnet on the electric refrigerator housing body steel plate, electromagnet casing, the electromagnet top cover, the electromagnet cover plate is formed, coil is arranged in electromagnet casing, also have electromagnet sleeve in the electromagnet bonnet, the afterbody of electromagnet armature can slide in electromagnet sleeve, and back-moving spring is contained on the electromagnet armature push rod.Be screwed the bump cushion block on the door body, the control circuit switch of coil is on electric refrigerator housing body or door body.When the button of the apparatus for door-opening of pressing refrigerator, coil electricity, around coil, produce magnetic field, it is protruding that magnetic field promotes electromagnet armature, also from perforate, stretch out simultaneously together with cushion rubber bumper fixed thereon, cushion rubber bumper is passed to power the bump cushion block that is fixed on the door of refrigerator body, make the door body of refrigerator overcome magnet in the sealing strip of door body for the absorption affinity of electric refrigerator housing body steel plate, (employing this this does not have stop with novel refrigerator), break away from casing, actuation button so just realized with very little power, as long as just can realize the door of refrigerator is opened.After door opened, coil will cut off the power supply automatically, magnetic field diminishes, and by being contained in the effect of the back-moving spring on the electromagnet armature push rod, electromagnet armature is got back to original position again.

The utility model has following good effect: owing to be provided with electromagnet armature on electric refrigerator housing body, the back-moving spring that is fixed on the cushion pad on the electromagnet armature and connects together with electromagnet armature, and the bump cushion block is housed on relevant position on the door of refrigerator body, during button on pressing control circuit, produce magnetic field after the coil electricity, promote to move before the electromagnet armature, electromagnet armature is passed to power the bump cushion block that is fixed on the door of refrigerator body by cushion rubber bumper fixed thereon again, refrigerator doors is open, has avoided making the hand end to fill liquid or the plate of the article that easily easily are scattered or the liquid in the bowl or the article that easily are scattered spill or are scattered out.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail:

Fig. 1 is the structure cross-sectional schematic of the utility model door of refrigerator electromagnetic start device.

In the accompanying drawings, 1 is electromagnet, 16 give the chamber of leaving a blank for electric refrigerator housing body, 18,19 is the electric refrigerator housing body steel plate, and 7 is electromagnet armature, and 71 is the electromagnet armature push rod, 72 is the electromagnet armature afterbody, 14 is the electromagnetism axle sleeve, and 9 is the electromagnet back shroud, and 15 is electromagnet casing, 8 is coil, 10 is the electromagnet top cover, and 11 is the electromagnet cover plate, and 12 is hold-down screw, 2 is cushion pad, 6 is the door of refrigerator body, and 5 is the door foaming layer, and 3 are the bump cushion block, 13 is screw, 4 is the electromagnet back-moving spring, and electromagnet 1 is equipped with in giving in the chamber 4 of leaving a blank of the foaming layer 5 on electric refrigerator housing body, back-moving spring 4, on casing, leave perforate 17, at the front end of electromagnet 1, at perforate 17 places, cushion rubber bumper 2 is housed, electromagnet 1 is by electromagnet armature 7, and is fixed on the electromagnet bonnet 9 on the electric refrigerator housing body steel plate 19, electromagnet casing 15, electromagnet top cover 10, electromagnet cover plate 11 is formed, and coil 8 is arranged in electromagnet casing 15, also has electromagnet sleeve 14 in electromagnet bonnet 9, the afterbody of electromagnet armature 7 can slide in electromagnet sleeve 14, back-moving spring 4 is contained on the push rod 71 of electromagnet armature 7, is fixed with bump cushion block 3 with screw 13 on the door body, and the control circuit switch of coil 8 is on casing or door body.Electromagnet 1 is fixed on the central sill or upper and lower beam of casing of refrigerator.When the button of the electromagnetism opening device of pressing door of refrigerator, coil 8 energisings, around coil 8, produce magnetic field, magnetic field promotes electromagnet armature 7, and is protruding, also releases together with cushion rubber bumper 2 simultaneously, back down the bump cushion block 3 on the panel, make the door of refrigerator body be separated from the doorframe of electric refrigerator housing body, realization can be opened door only with pressing button.After door opened, the coil 8 of electromagnet armature 7 will cut off the power supply automatically, magnetic field diminishes, and the effect of push rod 71 back-moving springs 4 by being contained in electromagnet armature 7 makes electromagnet armature 7 get back to original position again.
