BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the field of refrigeration technologies and, in particular, to a refrigeration appliance and a door body thereof.

The poor sealing performance of door bodies of existing refrigeration appliances such as some refrigerators may affect the performance of the corresponding refrigeration appliances.

BRIEF SUMMARY OF THE INVENTION

It is accordingly an object of the invention to provide an improved refrigeration appliance and a door body thereof, which overcome the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type.

With the foregoing and other objects in view there is provided, in accordance with the invention, a door body for a refrigeration appliance, including a main part, a frame surrounding the main part, the frame including a housing with a cavity, the cavity being filled with an insulation material in contact with the main part, a door seal mounted on a rear side of the housing, and a seal strip located between the housing and the main part.

In some embodiments, the seal strip is located on an inner side of the door seal.

In some embodiments, the seal strip is located on a front side of the door seal.

In some embodiments, the seal strip includes a polyurethane adhesive.

In some embodiments, the housing includes a mounting part mounted with the door seal, the mounting part protruding toward the main part, and the cavity including a first cavity outside the mounting part and a second cavity inside the mounting part.

In some embodiments, the cavity includes a slit located between the mounting part and the main part and placing the first cavity in communication with the second cavity, a size of the slit in a thickness direction of the door body is smaller than the sizes of the first cavity and the second cavity, and the slit includes the insulation material.

In some embodiments, the housing includes an inner wall, the seal strip fills-in between the inner wall and the main part, and the second cavity is located among or between the inner wall, the main part and the mounting part.

In some embodiments, the second cavity accommodates the insulation material.

In some embodiments, the second cavity includes a gas insulation layer in contact with the insulation material.

In some embodiments, the insulation material includes an insulation material made of a foaming material.

In some embodiments, the housing includes a rear frame part, a lateral frame part connected to the rear frame part, and an inner wall bent forward from an inner side of the rear frame part to extend toward the main part, and the seal strip is located between the inner wall and the main part.

In some embodiments, the main part includes at least two layers of separated glass plates.

With the objects of the invention in view, there is concomitantly provided a refrigeration appliance, including the foregoing door body.

Other features which are considered as characteristic for the invention are set forth in the appended claims.

Although the invention is illustrated and described herein as embodied in a refrigeration appliance and a door body thereof, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.

The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
