Technical field

The utility model relates to a kind of electric fan, particularly with the electric fan of conductor refrigeration device as low-temperature receiver.

Background technique

With the close prior art of the present invention is electric fan, and its structure mainly comprises micromachine, fan leaf, base, protective housing and control circuit board, regulation and control knob (comprising that temperature is adjusted knob, wind speed is adjusted knob etc.).The minitype motor driving fan leaf rotates, and makes the air flows of local environment, thereby takes away heat, reaches the cooling purpose.This class electric fan is convenient to move, and is easy to use, but shortcoming is to change ambient temperature, and thermoregulation effect is relatively poor.

Summary of the invention

The technical problems to be solved in the utility model is, overcomes the shortcoming of background technique and a kind of electronic product of designing.It can change local ambient temperature and improve thermoregulation effect, still can move easily, and environmentally safe, energy consumption and cost are lower.

The technical problems to be solved in the utility model is achieved in that utilizes conductor refrigeration sheet energising back because paltie effect can make the temperature of its huyashi-chuuka (cold chinese-style noodles) reduce, and hot-face temperature rises.Huyashi-chuuka (cold chinese-style noodles) is used for the refrigeration and heat radiator ambient air, utilizes the rotation of micro fan blade that cool air is sent.

Concrete structure of the present utility model comprises shell, micro fan, regulation and control knob, power switch is housed on shell, control circuit board is housed in the enclosure, control circuit board is installed DC electrical source, different with background technique is that structure also comprises conductor refrigeration sheet, radiator, mini fan, ventilation flue, cold and hot radiating fin; The conductor refrigeration sheet is installed in the enclosure, and one side wherein is close with radiator, and another side and cold and hot radiating fin are close; One end of ventilation flue is equipped with mini fan, and the other end is equipped with exhaust port, and cold and hot radiating fin is contained in the ventilation flue; The inner side surface of radiator dress micro fan, outer side surface is relative with venetian blind on being contained in shell.

Said control circuit board is the wiring plate that an installation DC electrical source and power supply are electrically connected with consuming parts such as conductor refrigeration sheet, mini fan, micro fans.Each consuming parts is in parallel, and power supply provides 12V direct current through power switch for each consuming parts.

Temperature adjust knob, wind speed adjust knob respectively with conductor refrigeration sheet, micro fan coupled in series.Being connected cold and hot alteration switch between DC electrical source and conductor refrigeration sheet, is the current direction that the conductor refrigeration sheet changes power supply, thereby changes the direction of conductor refrigeration sheet huyashi-chuuka (cold chinese-style noodles) and hot side, making the fan that adjusts the temperature electronically realize the transformation of cold and hot function.That is, when conductor refrigeration sheet huyashi-chuuka (cold chinese-style noodles) contacts with radiator, micro fan blows out venetian blind with cold wind, makes environment temperature reduction; Utilize cold and hot alteration switch to change the direct current supply direction of conductor refrigeration sheet, then conductor refrigeration sheet hot side contacts with radiator, and micro fan blows out venetian blind with hot blast, and environment is heated up.

Said conductor refrigeration sheet can use the 2-8 sheet side by side, to strengthen refrigeration.When using 2-8 chip semiconductor refrigerating plate, can use two cold and hot radiating fin and bilateral air channel.

The utility model is compared with background technique, has both had electric fan and has been convenient to move, and is easy to use, the advantage that cost is low, have again simple in structure, can change ambient temperature, the better characteristics of refrigeration.Littler than air conditioner volume, and do not have the pollution of chemical refrigerant to environment, energy consumption and cost are all lower.The utility model is very suitable for local use such as family room, office, operator cabin, hospital ward.
