Abstract

The invention relates to a door body of a refrigerator freezer room, which comprises a door panel, a door inner chamber, an upper positioning plate, a lower positioning plate and a foam insulation layer as well as a stiffening plate made of a plurality of bamboo rods, wherein the stiffening plate is parallel to the door inner chamber, and an included angle with the plane is formed and is less than or equal to 90 degrees and is greater than or equal to 0 degree. Because of the adoption of such structure, the stiffening plate made of the bamboo rods has toughness so as to effectively neutralize bending deformation force of the door panel and the door inner chamber and keep the original shape of the door so that the door body is prevented from deforming; the stiffening plate made of the bamboo rods has a plurality of bamboo joints which can enforce the combination force between the foam insulation layer and the stiffening plate so that the door body has high integrality and the function of deformation prevention is increased. Compared with metal stiffening plates in the prior art, the stiffening plate made of the bamboo rods has good toughness, high deformation-resistant capability, low cost and light weight.

Description

A kind of door body of freezer chamber of refrigerator

Technical field

The present invention relates to the device of refrigerator, especially a kind of door body of freezer chamber of refrigerator.

Background technology

Present prior art, a kind of door body of freezer chamber of refrigerator, comprise door face board, door inner chamber, last location-plate, following location-plate, metal reinforcing plates and insulating foam layer, insulating foam layer coated metal stiffener, insulating foam layer is with door face board, and upper and lower location-plate and door inner chamber are fixed together.Existing problems are: the cost height, the door body weight is big, does not still prevent the flexural deformation of door height direction, and leaks cold air.

Summary of the invention

The objective of the invention is: a kind of door body of freezer chamber of refrigerator is provided, and it not only can effectively reduce cost, and reduces the weight of door body, but also can effectively prevent a body flexural deformation.

The present invention is achieved in that a kind of door body of freezer chamber of refrigerator, comprise door face board, door inner chamber, go up location-plate, following location-plate and insulating foam layer, its special character is: also comprise the stiffener that some bamboo bar material are made, stiffener is parallel with the door inner chamber;

Stiffener and horizontal plane have smaller or equal to 90 degree, more than or equal to 0 angle of spending.

The door body of described a kind of freezer chamber of refrigerator, its special character is: described stiffener is circular arc perpendicular to the cross section of its length direction.

The door body of described a kind of freezer chamber of refrigerator, its special character is: the center of circle side of the stiffener of described circular arc is relative with door face board; Also comprise the cylinder that several are heat insulation, cylinder one end contacts with the door inner chamber, the other end contacts insulating foam layer parcel cylinder and stiffener with stiffener.

The door body of described a kind of freezer chamber of refrigerator, its special character is: described stiffener is adjacent with the door inner chamber.

The door body of a kind of freezer chamber of refrigerator of the present invention owing to adopt such structure, because the stiffener that the bamboo bar material is made has toughness, can be offset door face board, door inner chamber flexural deformation power effectively, keeps the original shape of door, and prevents a body deformability; Some rings are arranged on the stiffener that the bamboo wood material is made, and the existence of ring has increased insulating foam layer and stiffener adhesion, and globality is strong, has increased the effect of being out of shape of preventing again.The stiffener that the bamboo wood material is made is compared with metal reinforcing plates of the prior art, good toughness, and the anti-deformation ability is strong, and cost is low, and is in light weight.

Description of drawings

Fig. 1 is a front view of the present invention.

Fig. 2 is A-A view of Fig. 1.

Fig. 3 is the partial enlarged drawing of Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

As shown in Figure 1 and Figure 2, a kind of door body of freezer chamber of refrigerator comprises door face board 1, door inner chamber 2, goes up location-plate 31, following location-plate 32 and insulating foam layer 4, also comprises the stiffener 5 that some bamboo bar material are made, and stiffener 5 is parallel with door inner chamber 2.Described stiffener 5 is adjacent with door inner chamber 2;

Upper and lower location-plate 31,32 can be parallel to the horizontal plane setting, also can be perpendicular to the horizontal plane setting.

Stiffener 5 has smaller or equal to 90 degree, more than or equal to 0 angle of spending with horizontal plane.

As shown in Figure 2, described stiffener 5 is circular arc perpendicular to the cross section of its length direction.

As shown in Figure 3, the center of circle side of the stiffener 5 of described circular arc is relative with door face board 1; Also comprise several heat insulation cylinders 6, cylinder 6 one ends contact with door inner chamber 2, the other end contacts with stiffener 5, insulating foam layer 4 parcel cylinder 6 and stiffeners 5.Realization cylinder 6 is fixedlyed connected with stiffener 5 with a door inner chamber 2.The employing of cylinder 6 more helps bringing into play the toughness of stiffener.

Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
