The utility model provides a refrigerator, which adopts a circulation mode of air inlet and outlet at the front end, prolongs air circulation distance by limiting and using an inside-sealed air channel with a specific trend, effectively utilizes convection current to cooling the inside of a machinery room, and accordingly can meet the requirements of a high-power refrigerant system. The refrigerator comprises a casing, and a hollow cabinet body and the machinery room are arranged inside the casing, wherein the cabinet body is capable of storing foods airtightly, and the machinery room is arranged at the bottom of the cabinet body and provided with a refrigerant circulation pipeline and refrigeration parts. An air inlet and an air outlet which are not communicated with each other are arranged at the front end of the machinery room and arranged at two ends of an inside circulation air channel formed by the machinery room respectively. A fan for forming inside air circulation of the machinery room is arranged at the position of the air inlet or the air outlet.

Description

Refrigerator

Technical field

The utility model relates to a kind of cold drink or cold food of providing to be sold and the refrigerator of showing, belongs to commercial appliance and mechanical manufacturing field.

Background technology

Provide the commercial display cases of cold drink or cold food mainly to be divided into vertical or horizontal 2 kinds of appearance structures to the consumer; Receive the restriction of the interior space owing to public places such as being disposed at eating and drinking establishment, bar, market at large; Provide in time, easily in the provand, Aided Design that need cool especially and processing.

Existing horizontal or vertical commercial display cases is placed on position comparatively narrow and small or sealing comparatively at large, therefore also just adopts the pipeline cooling method of the air-cooled circulation in bottom morely.Consider that utilization rate, the space of improving the cabinet internal storage space place the restriction that flows to air circulation, present air channel trend, structural design are unreasonable, are difficult to satisfy the cooling requirement of high-power refrigerant system.

For example, the air circulation mode of air intake, back air-out then need be reserved enough rear portions or side spaces before adopting, and this has relatively high expectations for refrigerator usage space area, is unfavorable for the use of existing commercial indoor environment.If the endless form of air intake, preceding air-out before adopting; Existing air channel is used and turbulent flow can be occurred again; Circulation line and refrigeration part surface temperature descend slowly, and it is slower to embody a concentrated expression of the inner storage temperature decline of cabinet, and are difficult to reach the preservation temperature of the best mouthfeel of food.

In view of this, the special present patent application that proposes.

The utility model content

The described refrigerator of the utility model; Its purpose of design is to solve the problem that above-mentioned prior art exists and takes the endless form of front end air intake and air-out; Through limiting and use air channel particular orientation, enclose inside improving the air circulation distance, to effectively utilize convection current and implement the cabin internal cooling and handle, thereby can reach the requirement of high-power refrigerant system.

Another purpose of design is, need not into refrigerator reserve rear portion and sidepiece to fluid space, can be adapted to the use of specific or narrow and small indoor environment.

For realizing above-mentioned purpose of design, described refrigerator mainly includes:

Housing is provided with cabinet hollow, can airtight storage food in enclosure interior, and is arranged on bottom of cabinet bulk, is equipped with the cabin of medium circulation pipeline and refrigeration part.

The difference with the prior art part is, is provided with mutual disconnected air inlet and air outlet at the front end of cabin, and air inlet, air outlet are separately positioned on the two ends in the formed inner loop of cabin air channel;

Be provided with the blower fan that is used to form the circulation of cabin inner air at air inlet or air outlet place.

And the place is provided with plate type condenser at air inlet.

In addition, along vertical direction, cabin has low early and high after step structure; Be provided with compressor and forced ventilation heat exchange condensers at the rear portion of cabin, along the air circulation direction, the forced ventilation heat exchange condensers is positioned at the windward side of compressor.

Content to sum up, the advantage that described refrigerator has has:

1, adopt the endless form of front end air intake and air-out, the air channel of optimizing through inside reduces windage as much as possible, and with air circulation apart from maximization, to improve the cooling efficient of cross-ventilation realization significantly, can satisfy the service requirement of high-power refrigerant system.

2, need not into refrigerator reserve rear portion and sidepiece to fluid space, be adapted to the requirement of many refrigerators combination uses, specific or narrow and small indoor environment especially.

3, owing to casing rear portion, left part, right part and top, bottom seal fully, improved the waterproof and dustproof performance of refrigerator greatly.
