Abstract
The present invention relates to an electromagnetic pneumatic damping open device for a door of a refrigerator. The present invention is composed of an electromagnet (1), an electromagnet reset spring (4), a damping cylinder (23), a bumper pad (2) and a fixed striking pad block (3) on a door body of the refrigerator. After the present invention is switched on, electromagnetic armature iron (7) pushes a piston rod (24) of the damping cylinder (23), a compression reset spring (4) and a piston (22) to forward move under the function of the magnetic field of an electromagnet coil (8). Air is absorbed by a big hole (13) which is arranged on the cylinder body (23), and the air which is compressed in the cylinder body (23) is gradually exhausted by a throttling effect of a throttling small hole (26). The armature iron (7) stably drives the piston rod (24) and the bumper pad (2) which is fixed on piston rod to extend out of an opening hole (27), and then, a door is slowly opened. Simultaneously, the present invention is automatically switched off, and the electromagnetic armature iron (7) automatically resets. When turned on, the open device does not generate impact, and articles in a hand are stable so that the articles can not scatter.
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 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 during to the absorption affinity of the steel plate of electric refrigerator housing body, door promptly is opened.Before the present invention generated, 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.Opening the door in a flash, will make refrigerator produce shake, at this moment,, will spill or be scattered out owing to overexerting and moving all of a sudden if Sheng is arranged by the plate of liquid or other article that easily are scattered, bowl etc. in another hand middle-end.
Purpose of the present invention, just be to overcome the opening device (promptly by door handle or by the panel of door or the built-in door handle of steel plate deformation generation) 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 calutron is provided, and have the door of refrigerator that the air damping device is opened, realize opening the door steadily.
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 electromagnetic pneumatic damping opening device for electric refrigerator, this device is in the reservation cavity by foaming layer on electric refrigerator housing body, electromagnet is housed, the electromagnet back-moving spring, damped cylinder, cushion pad and the bump cushion block of fixing on the door body are formed, electromagnet links to each other with piston rod, piston rod links to each other with cushion pad, the electromagnet back-moving spring is fixed on the piston rod, said electromagnet is by electromagnet armature, the electromagnet bonnet, electromagnet casing and electromagnet top cover are formed, coil is arranged in electromagnet casing, afterbody at electromagnet armature has axle sleeve, afterbody can slide in axle sleeve, the control circuit switch of coil is on electric refrigerator housing body, said damped cylinder is by cylinder body, piston rod, piston, sealing ring is formed, the hole that the electromagnet top cover has electromagnet to stretch out, the front end of electromagnet armature are passed the hole and are linked to each other with piston rod, in the groove between piston and the cylinder body sealing ring are arranged, front end at piston rod also has a sealing ring, throttling pore is arranged on cylinder body, on cylinder body, also have macropore, be fixed on the cushion pad of the front end of piston rod, aperture by leaving on casing stretches out casing.
In technique scheme, said electromagnet is fixed on central sill, upper beam or the underbeam of electric refrigerator housing body.
In technique scheme, said cushion pad is made by rubber or Polyurethane.
When the coil control circuit switch of pressing electromagnet on electric refrigerator housing body, circuit is switched on, form magnetic field around the coil, it is protruding that magnetic field promotes electromagnet armature, the piston rod that promotion connects together with it, compression reseting spring, piston forward moves, by being located at the macropore on the cylinder body, suck air does not make cylinder generation thrust round about, sealing ring makes and is in sealing state between piston and the cylinder body, the air that is compressed in cylinder body is discharged gradually by the throttling action of throttling pore, reaches the thrust of electromagnet armature generation and the pressure balance of damping cylinder, will play buffering effect like this.Armature drives piston rod stably and the cushion pad that is fixed in the above stretches out the perforate of reserving on the electric refrigerator housing body, promotes to be in the fixing bump cushion block on the door of closed condition, and door just is opened reposefully at leisure.After chamber door was opened, coil will cut off the power supply automatically, magnetic field diminishes, and the electromagnet back-moving spring that is compressed that is fixed on the piston rod just restores to the original state gradually, gets back to original position again by its effect electromagnet armature.
The present invention has following good effect: owing to be provided with on electric refrigerator housing body by electromagnet armature, the electromagnet back-moving spring, damped cylinder, cushion pad and the electromagnetic pneumatic damping opening device that fixing bump cushion block is formed on the door body, during button on pressing control circuit, coil electricity produces magnetic field, and the cushion pad thereon that promotes the piston rod of electromagnet armature drive damped cylinder is opened the door body inchmeal.Not producing shake, do not produce impact sound yet, is not that the liquid in the plate that fills liquid or other article that easily are scattered that has of hand middle-end, the bowl or the article that easily are scattered spill or are scattered out.
