Description

Handle assembly for refrigerator-freezer and refrigerator-freezer

technical field

The invention relates to refrigerating and freezing technology, in particular to a handle assembly for a refrigerating and freezing device and a refrigerating and freezing device.

Background technique

There are two kinds of handles on the common refrigerating and freezing devices, such as refrigerators, which are open handles and dark handles. The open handle is an arc or straight handle protruding from the plane of the refrigerator door body, which is fixed by fixing bolts at both ends. However, the entire exposed handle is exposed outside the door body, and the installation position of the handle has a relatively large space size, which increases the overall size of the refrigerator. Therefore, gradually, there are fewer and fewer exposed handle products. Refrigerators with concealed handles have begun to appear in large numbers. The common concealed handles are recessed inwards on the door of the refrigerator to form a gap that can be used as a handle. However, due to the limitation of the thickness of the foam layer, the space for the handle gap is very small. More seriously, the hidden handle needs to be embedded in the door body, which occupies the volume of the door body foam layer and reduces the door body thermal insulation performance. Condensation easily occurs. In addition, in order not to affect the thermal insulation function of the foam layer, the recessed part will occupy the volume inside the refrigerator, so that the available volume of the refrigerator is reduced.
