Cabinet frames for refrigerated cabinets and refrigerated cabinets

Abstract

The invention relates to a cabinet frame for a refrigerated cabinet, on at least a part of the outer surface of the cabinet frame an additional layer made of a material with low thermal conductivity is arranged and the additional layer is arranged to communicate with the The outer surfaces are spaced apart from each other, and the air gap communicates with the outside air. The invention also relates to a refrigerated cabinet comprising a cabinet body, at least one cabinet door and a cabinet frame as described above, wherein the cabinet frame is attached to the cabinet body and the cabinet door is attached to the cabinet frame. Adopting the present invention can fully and effectively prevent external humid air from condensing on the outer surface of the refrigerator without setting heating components such as electric heaters, which is not only beneficial to control the manufacturing cost of the refrigerator and improve its operational reliability, Moreover, it can save the working energy consumption of the refrigerator, thereby significantly reducing the operating expenses of the equipment. The invention has great significance for realizing the goals of reducing carbon emissions, energy saving and environmental protection.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, and in particular, to a cabinet frame and a refrigerating cabinet for a refrigerating cabinet. Background technique [0002] Various types of refrigeration equipment with refrigeration, freezing or both display functions, such as freezers, refrigerators, and refrigerated display cabinets, have been widely used in people's daily work, life and business activities. Collectively referred to as "refrigerating cabinet". Although these refrigerators can bring people infinite convenience and enjoyment, there are also some problems and shortcomings in the actual use process. For example, various types of refrigerated cabinets will consume a lot of energy including electrical energy when working. Since the number of refrigerated cabinets currently in use is quite large, this energy consumption is very alarming, and it is necessary to study and make improve. [0003] As far as th...

Problems solved by technology

Undoubtedly, these devices will consume a considerable amount of electric energy in the long-term operation day after day, which is not only against the practical requirements of energy saving, environmental protection, etc., but also because these heating devices work for a long time in relatively It may be prone to failure or damage in low temperature and humid environment, thus increasing equipment maintenance costs and is not conducive to the long-term reliable operation of the refrigerator itself

[0004] Although a glass door for refrigeration or freezing and a refrigerator door with a thermally insulating outer frame have been disclosed in U.S. Patent No. US4496201 issued to Allgeyer and U.S. Patent No. US4741127 issued to Bockwinkel, respectively, The structure of these doors is not only relatively complicated, but also has to be completely remanufactured in order to use it, and it is impossible to remove the above-mentioned heating device and achieve a saving effect by properly modifying the structure of the existing refrigerator
