Abstract

The utility model relates to a small-scale refrigeration device. The small-scale refrigeration device comprises a base part, a peripheral wall extending upwards along the periphery of the base part and a cover body covered on the top edge of the peripheral wall; the base part, the peripheral wall and the cover body enclose a receiving space; the peripheral wall and the base part respectively comprise a two-layer structure with an inner layer and an outer layer; a refrigerating device is arranged between the inner layer and the outer layer; the refrigerating device comprises a thermal conductive block adhered on the outside of the inner layer, an electronic refrigerating plate adhered on the outside of the thermal conductive block and a control circuit module connected with the electronic refrigerating plate; the cold end of the electronic refrigerating plate is adhered on the outside of the thermal conductive block; and the thermal end of the electronic refrigerating plate faces outwards. The small-scale refrigeration device has a small size, can be carried conveniently and be positioned on a desk for use; the small-scale refrigeration device is connected with the electronic refrigerating plate by the thermal conductive block instead of the direct contact between the electronic refrigerating plate and the inner sidewall; through experiments, the small-scale refrigeration device has better refrigerating effect.

Description

A kind of small-sized cold storage plant

Technical field

The utility model relates to the small household appliances field, specifically is meant a kind of small-sized cold storage plant.

Background technology

Existing common cold storage plant is refrigerator, refrigerator or refrigerating chamber etc. for example, the shortcoming that have all that volume is big, complex structure, inconvenience moves, even aim at the small refrigerator of unmarried person design, also be usually fixed placement in some positions, it also is very inconvenient moving.

In actual life, people usually can meet some occasions that need small-sized cold storage plant, for example, from refrigerator take out cold drink when drinking cold drink hot day, if in time do not finish off, then the temperature of cold drink can be very fast along with temperature on every side raises, and people can not put into refrigerator again after drinking several mouthfuls, want after a while to drink again and take out from refrigerator, and such operation too bothers; For another example, when people ate icecream, regular meeting ran into that icecream has just melted when also not eating up.Therefore, people need a kind of conveniently can with small-sized cold storage plant.

The utility model content

Main purpose of the present utility model be to provide a kind of conveniently can be with, the small-sized cold storage plant that can be easily some cold drinks or frozen food be refrigerated.

The utility model adopts following technical scheme: a kind of small-sized cold storage plant, comprise a bottom, from upwardly extending leg of this bottom peripheral edge and the lid that is covered on the leg apical margin, this bottom, leg and lid surround an accommodation space, it is characterized in that: this leg, the bottom includes interior outer double-layer structure, be provided with chiller within it between the skin, this chiller comprises the heat-conducting block that is attached at the internal layer outside, be attached at the electron cooling sheet in the heat-conducting block outside and the control circuit module that is electrically connected with the electron cooling sheet, the cold junction of electron cooling sheet fits in the heat-conducting block outside, and the hot junction outwardly.

Aforementioned a kind of small-sized cold storage plant, the hot junction of its electron cooling sheet is provided with fin, and the fin outside is provided with fan.

Aforementioned a kind of small-sized cold storage plant, the thickness of its heat-conducting block is the 5-25 millimeter.

Aforementioned a kind of small-sized cold storage plant, its control circuit module is provided with power switch, and this power switch is located at the lateral surface of described leg.

By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, when people drank cold drink or ate frozen food hot day, beverage or frozen food can be temporary in this cold storage plant, make cold drink or eat frozen food by its refrigeration to keep under the low-temperature condition, people do not worry that beverage or frozen food influence because of the high heating of environment temperature and drink; Two, this cold storage plant volume is little, can carry conveniently, can be positioned on the desktop and use; Three, be connected with the electron cooling sheet by a heat-conducting block, rather than the electron cooling sheet is directly contacted with madial wall, through test, such cooling effect is better.

Description of drawings

Fig. 1 is a vertical section structure schematic diagram of the present utility model.

The specific embodiment

The specific embodiment of the present utility model is described with reference to the accompanying drawings.

A kind of small-sized cold storage plant, with reference to Fig. 1, comprise a bottom 1, upwardly extending leg 2 of this bottom 1 periphery and the lid 3 that is covered on leg 2 apical margins certainly, this bottom 1, leg 2 and lid 3 surround an accommodation space 10, and bottom 1 and leg 2 all have internal layer 11, outer 12 double-decker.

With reference to Fig. 1, be provided with

chiller

4,5,6 between the layer 11 and outer 12 within it, be used to make the food of preservation in the accommodation space 10 to remain under the low-temperature condition.Chiller 4 is located in the bottom 1, and chiller 5,6 is located in the leg 2, and how much being not limited thereto of chiller quantity can be provided with as required.

With reference to Fig. 1, this chiller 4 comprise the heat-conducting block 401 that is attached at internal layer 11 outsides, the electron cooling sheet 402 that is attached at heat-conducting block 401 outsides and and the control circuit module 7 that is electrically connected of electron cooling sheet 402, the cold junction of electron cooling sheet 402 fits in heat-conducting block 401 outsides, and the hot junction outwardly.The hot junction of this electron cooling sheet 402 is provided with fin 404, and fin 404 outsides are provided with fan 405, and the position with respect to fan 405 on the skin 12 is provided with louvre 406.Be folded with fixing support rack 403 between electron cooling sheet 402 and the fin 404, this fixing support rack 403 is fixed on outer 12, and each parts is played fixed support.The thickness of this heat-conducting block 401 can be selected between the scope of 5-25 millimeter.

Control circuit module 7 is provided with power switch 8, and this power switch 8 is located at the lateral surface of leg 2.

Chiller 5,6 structures are identical with the structure of above-mentioned chiller 4.
