Embodiment 1

[0022] Referring to Figs. 1-2, the inner door seal of the present invention is assembled in the matching groove of the inner liner 3 of the door, and is the second door seal (not shown) on the inner side of the outer door seal. Different from the outer door seal, the inner door seal does not have a magnetic strip, and its working principle is to rely on the elastic deformation of the airbag part to form a closed space between the door and the box to prevent cold air from leaking out. The inner door seal includes two parts, the mounting foot and the air bag, both of which are extruded at the same time. There is a spacer in the middle of the airbag 2, and the airbag is divided into two air chambers, front and rear, and a pair of linear fins 4 and 5 separated sideways are arranged on the outer end surface of the front air chamber. The thickness is small, and the thinning treatment at the root can enhance the stress deformation capacity of the fin. When the door was closed, the f...

Embodiment 2

[0026] See Figure 3, it is an inner door seal with a simple structure, which adopts a single airbag design. There are linear fins 4 and 5 on the outer end plane, and there are fins 8 at the root of the airbag. There is no spacer in the airbag. There is no shrapnel structure, and its advantage is that it can realize effective sealing between the door body and the box body, and has simple structure and low cost.

Embodiment 3

[0028] Referring to Fig. 4, on the basis of the second embodiment, the spacer inside the airbag is added to improve the heat insulation of the door seal.

Abstract

The invention discloses an inner door sealing structure of fridge, which comprises the following parts: air bag, assembling foot on the door of fridge, wherein the inner door seal is set at inner side of main door seal; the fin is set on the external end face of air bag to seal; the thickness of root of fin is less than the thickness of wing part. The invention seals the inner door of fridge effectively without insufficient elastic and weak adaptation problem, which improves the energy-saving effect of fridge greatly.

Description

technical field [0001] The invention relates to a refrigerator sealing structure, and more specifically relates to a refrigerator inner door sealing structure which can effectively prevent external heat from entering into the refrigerator, thereby reducing the energy consumption of the refrigerator. Background technique [0002] For refrigeration appliances such as refrigerators, in order to prevent the loss of cooling capacity and the heat transfer caused by the temperature difference between the inside and outside when the door is opened, it is necessary to equip an efficient door seal structure. At present, energy-saving refrigerators are basically equipped with double door seals, including the main The door seal and the inner door seal are double-layered to ensure that the cooling capacity does not leak. The main door seal is outside the magnetic door seal (with magnetic strips, which can be attached to the metal side of the cabinet) equipped on the door frame of the ref...
