Abstract

A novel door sealing structure for a refrigerator comprises an air bag, a refrigerator liner, a refrigerator door pot. The potion which air bag contacting to the refrigerator liner is a protruding potion forming an interference assembling structure with the refrigerator liner. The interference area of the air bag is between 15-25 square millimetres. The gap between at the right part of the door seal between the refrigerator liner and the refrigerator door pot is below 1 mm; the shapes of the refrigerator liner and the refrigerator door pot are mutually matched. Because of the technical solution, the utility model has the following beneficial effects: simple structure; reducing the heat load at the door sealing position by using the assembling structure of the refrigerator liner and the refrigerator door pot.

Description

The type gate seal structure that can be used for refrigerator

Technical field

The utility model belongs to technical field of electric appliances, relates to refrigerator, especially the door envelope of refrigerator.

Background technology

Used door envelope mainly for the casing that seals refrigerator and the gap between the door body, reduces in the case and the outer heat exchange of case on the refrigerator.The refrigerator doors envelope generally realizes that by designing a plurality of air bags the shortcoming of doing like this has 2 in order better to reduce thermic load herein at present: 1, be the area of section that increases crack between a door and its frame, fee of material increases; 2, air bag is many, and the vertical rigidity of door envelope has increased, and integral hardness increases, and is difficult for stretcher strain, influences seal degree.

As shown in Figure 1, the door envelope part of refrigerator comprises refrigerator door liner 11; Door envelope 12; Inner container of icebox 13; Refrigerator case shell 14; Door envelope magnetic stripe part 15; Air bag 16; Door envelope PVC part 17.

There is magnetic stripe door envelope 12 inside, and when closing door, door envelope 12 is adsorbed onto on the refrigerator case shell 14, and the air bag 16 of door envelope plays heat-blocking action.Owing to must stay the fit-up gap between inner container of icebox 13 and the refrigerator door liner 11, cause this part heat-insulating capability the weakest, become the important source of the thermic load of refrigerator stable operation.Though door envelope 12 sectional areas in this cross section are little, air bag 16 irrational distribution, air bag 16 of no use is sealed the gap between inner container of icebox 13 and the refrigerator door liner 11, and the thermic load at door envelope 12 places is bigger like this.

The utility model content

The purpose of this utility model is to provide a kind of type gate seal structure that can be used for refrigerator, under the situation that does not increase present door envelope air bag number and area of section substantially, utilize inner bag, the level that assembling characteristics between door courage and the door envelope increases hermetic unit reduces the thermic load of door envelope part to distance.

For reaching above purpose, solution of the present utility model is:

A kind of type gate seal structure that can be used for refrigerator comprises air bag, inner container of icebox, refrigerator door liner, and the position that this air bag contacts with inner container of icebox has bossing and inner container of icebox forms the interference assembly structure.

Further: the interference area of this air bag is between the 15-25 square millimeter.

Gap that is positioned at the envelope right part between inner container of icebox and the refrigerator door liner is below 5mm, and the shape of inner container of icebox and refrigerator door liner is worked in coordination.

Owing to adopted above technical scheme, the utlity model has following beneficial effect: it is simple in structure, utilizes the assembly structure of inner container of icebox and door courage, has better reduced the thermic load at door envelope place.

The specific embodiment

Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.

A kind of new-type door envelope cross sectional shape of the utility model, it comprises refrigerator door liner 1, door envelope 2, inner container of icebox 3, refrigerator case shell 4, door envelope magnetic stripe part 5, air bag 6, door envelope PVC part 7, air bag bossing 8, and it needs being cooperated in shape of inner container of icebox 3 and refrigerator door liner 1.

Specific as follows: when closing, magnetic stripe part 5 pulling door envelopes 2 in the door envelope 2 are adsorbed onto on the refrigerator case shell 4, the air bag bossing 8 of the air bag 6 of door envelope 2 is under the squeezing action of refrigerator door liner 1 and inner container of icebox 3, distortion to the right, unnecessary part 61 just in time enters in the gap of refrigerator door liner 1 and inner container of icebox 3 formation, and as shown in Figure 4,61 parts are exactly the shape after 8 distortion of air bag bossing, the level that has enlarged sealing has reduced the thermic load of door envelope 2 parts to distance.

In order to effectively reduce the thermic load of an envelope, wherein the area of the unnecessary part 61 of air bag bossing 8 or air bag is between the 15-25 square millimeter, and the gap between inner container of icebox 3 and the refrigerator door liner 1 is not greater than 5mm, guarantees that like this level of door envelope increases more than the 3mm to seal distance.

Owing to only the shape of air bag has been done to change, do not increase the quantity of air bag, so the area of section increase of opposite house envelope is very little, the increase of fee of material also can be ignored substantially.

The shape of air bag just is meant the shape of PVC part in the envelope, deformable behind the soft pressurized, but be not subjected to pressure energy to keep own shape own, the alteration of form of air bag is meant that the original door upper right air bag of envelope (16 among Fig. 1) upper end is a level, and inner container of icebox (13 among Fig. 1) is hands-off, improve design back upper right air bag (6 among Fig. 2) change of shape, the upper end is level no longer, but raise up, the part of projection is and inner container of icebox (3 among Fig. 2) assembling is interference, and the contrast of Fig. 1 and Fig. 2 can be seen this point.

Because at present a refrigerator body or a door body deformability are universal phenomena, some areas of door envelope 2 may not be adsorbed onto on the refrigerator case shell 4, and the gap of door envelope 2 and refrigerator case shell 4 causes herein that thermic load sharply strengthens in this case, brings a lot of quality problem.Door envelope 2 right part air bag 6 assemblings in vertical direction in the utility model are interference, under door envelope 2 and refrigerator case shell 4 gapped situations, the unnecessary part 61 of the rearward projection that is squeezed of door envelope 2 right part air bags 6 can also seal the gap between refrigerator door liner 1 and the inner container of icebox 3.Reduced the thermic load of door envelope 2 parts in this case.

Sum up the emphasis that this technology is used:

1, door envelope cross section upper right quarter air bag 6 shapes raise up, and are interference assemblings at fit on and inner container of icebox 3, and the interference area will be between the 15-25 square millimeter.

2, the gap that is positioned at the envelope right part between inner container of icebox 3 and the refrigerator door liner 1 need under present domestic refrigerator level of production condition, can both reach this point substantially below 5mm.

The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the foregoing description, and those skilled in the art should be within protection domain of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
