Abstract

The utility model provides a sealing device for a door of a refrigerator. A concave-convex isosceles trapezoid, a semicircle or an equiangular triangle (select one of the three) is arranged around a refrigerator body and door sealing strips, and the concave-convex surface is coated with liquid (water or non-corrosive grease) to increase the adsorption area of the refrigerator body and door sealing strips and extrude the air to realize the sealing effect. The sealing device for a door of a refrigerator has the advantages of easy fabrication, small alteration, good practicability, strong sealing ability, long service life and electricity; in addition, the sealing device for a door of a refrigerator can extend the food fresh keeping time and the food storage time and decrease the work frequency of the compressor; thus, the goal of high efficiency and energy saving is realized. The sealing device for a door of a refrigerator can be used for sealing other products.

Description

Sealing apparatus for door of refrigerator

The utility model relates to a kind of door of refrigerator sealing device, after closing door of refrigerator, effectively the sealed electrical refrigerator doors around, reach energy-efficient and prolong refrigerator service life.

Energy-conservation, be the key subjects of every field research in the world wide, the refrigerator industry is no exception, and along with the China market prosperity of economy, " efficient energy-saving " of refrigerator also captures the major project that the domestic and international market is studied with regard to becoming domestic production producer.At present, planar magnetic absorption closing type is all adopted in the sealing of the door of refrigerator produced of refrigerator manufacturer both at home and abroad, though can solve certain problem, from actual effect: the one, it is bad to coincide, and often has edge dew to stitch; The 2nd, magnetic adsorptive power is not very strong; The 3rd, casing is not too high with door adsorption plane fineness; The 4th, their adsorption planes are narrow, thereby influence sealing causes refrigerator storage room and freezer temperature rise time short thus, and compressor operating frequency height, time are long, increase electricity consumption, influence food storing and shortening compressor life-span.In line with the policy of " energy-efficient ", develop the utility model-door of refrigerator sealing device, change the not enough problem of existing door of refrigerator sealing.At present, also there is not this type of device in the refrigerator product.

Task of the present utility model provides a kind of sealing device of door of refrigerator, after people close door of refrigerator, with absorption that increases door of refrigerator sealing strip and casing and the device that adopts liquid (water or noncorrosive grease) sealing, solve because of closing the poorly sealed problem of bringing, on the basis of existing equipment, can make food fresh keeping, store prolongation, reduce the compressor operating number of times, prolong its service life, using electricity wisely reaches the purpose of " energy-efficient ".

Utility model is achieved in that a refrigerator body (with the door weather strip anastomosis) makes recessed isosceles trapezoid, semicircle or equilateral triangle (choosing any one kind of them) all around, door of refrigerator sealing strip (containing Armco magnetic iron) make with the door of refrigerator body around the convex that is complementary of groove, coat liquid (water or do not have the corrosion grease) at concavo-convex body place.When refrigerator cuts out, increase the magnetic adsorption area, with the effect of liquid the air extrusion between male and fomale(M﹠F) is fallen, reach the purpose of sealing.This device also can be used on other product that need seal.Its concrete implementation step is as follows in conjunction with the accompanying drawings:

Fig. 1 is that figure is cutd open in the utility model casing front.

Fig. 2 is that the utility model casing trapezoidal groove cuts open figure.

Fig. 3 is that the utility model casing semi-circular recesses cuts open figure.

Fig. 4 is that the utility model casing equilateral triangle connected in star cuts open figure.

1. make refrigerator body (with the door weather strip anastomosis) Baltimore groove (1) all around earlier, see accompanying drawing Fig. 1 for details

2. three types of method for makings of above-mentioned Baltimore groove:

A. isosceles trapezoid: the wide 9mm(2 of upper opening), the long 8mm(3 of equilateral waist), the wide 5mm(4 in bottom), see accompanying drawing Fig. 2 for details

B. semicircle: as opening diameter 9mm(5), to see accompanying drawing Fig. 3 for details

C. equilateral triangle: length of side 9mm(6), see accompanying drawing Fig. 4 for details

3. door of refrigerator sealing strip (contain the inside magnet) is made the convex that Baltimore groove is complementary around the casing, figure slightly again.

Claims

1, one by spill (1) and door of refrigerator sealing strip convex around the refrigerator body, coat the door of refrigerator sealing device that liquid is formed at its concavo-convex place, and it is characterized in that: refrigerator body is made recessed isosceles trapezoid, semicircle and equilateral triangle all around.

2, according to the door of refrigerator sealing device of claim 1 defined, it is characterized in that: the door of refrigerator sealing strip make with refrigerator body around the convex that is complementary of spill.
