Background

The display cabinet is a display platform which is provided for commodity display and has a protection function. The novel multifunctional combined type exhibition hall is firm in structure, easy to disassemble and assemble and convenient to transport, is widely applied to company exhibition halls, exhibitions, department stores, advertisements and the like, and is widely applied to industries such as artware, gifts, jewelry, mobile phones, glasses, clocks, cigarettes, wines, cosmetics and the like.

However, different commodities have different characteristics and have certain relation with seasons, such as cold drinks in summer and hot drinks in winter, and the display cabinet has corresponding functions; present show cupboard function singleness, or can only refrigerate, or only keep warm, current heat preservation device only has the heating tube, because the air of cabinet body inner space is static, often only the peripheral temperature of heating tube rises to predetermineeing the temperature in the time of the heating, and other places do not have obvious intensification.

The top of the display cabinet is usually provided with a lamp box, a lamp box cover is made of transparent or semitransparent materials, and spray painting advertisement patterns or direct printing advertisements are pasted on the surface of the lamp box cover, so that the lamp box can play the roles of decoration and advertisement.

At present, the internal illumination and the lamp box illumination of the display cabinet on the market are separated, the overall energy consumption of the display cabinet is increased by the aid of the illumination mode, the number of lamps is large, and a light source is not well utilized.

In some refrigeration systems of display cabinets, oil stains and dust are easily accumulated on the surface of a condenser which is arranged in a cabinet body and used for heat exchange, so that the heat exchange difficulty of equipment is increased, the operation efficiency of the equipment is reduced, and the equipment is stopped seriously and cannot operate; meanwhile, the dust accumulation is easy to breed bacteria, so that the storage and the preservation of food in the display cabinet are extremely unfavorable and are avoided to the utmost extent. At present, no good solution to the problem exists, the surface of the condenser is generally cleaned manually, the manual cleaning consumes manpower and time, and the steps are complicated;

meanwhile, the cabinet door of the display cabinet needs to be closed in time in order to keep a low-temperature environment, and if the cabinet door is not closed in time, the refrigeration performance of the display cabinet can be affected.

Because the temperature difference between the temperature in the show cupboard and the external world is big, can lead to producing the comdenstion water on the outer glass of the cabinet body, for this reason, generally can use cavity heating glass to solve the problem of comdenstion water on the market, but cavity heating glass's heating scope has certain limitation, heats the part that can not reach the door frame, so the comdenstion water on the show cupboard door frame can't get rid of, has influenced user's use.
