Abstract
The utility model relates to an energy-saving electric fan for cooling and warming double purpose. The utility model is characterized in that a casing made of conductive plastics is arranged in the front of the fan, and both sides of the casing is provided with conductive metal products. In the way, a rib on the casing are equal to a plurality of resistors connected in parallel. When connected with the power supply, the rib heats, and the utility model blows hot air. The utility model can correspondingly blow cold air or hot air under the control of a switch, and is used for cold and hot seasons. The utility model has the advantages of simple structure, safety and easy fabrication, which is a replacement product of the electric fan.
Description
The utility model relates to a kind of electric fan of indoor use.
At present, well-known fan can only adapt to the wind that blows on hot day to be used, and no longer can use when weather turns cold.And common electrical heated filament electric heater, air heater only are suitable for the cold day heating, and naked light is arranged, and cause danger easily, and the thermal efficiency is also not too high, and best heat generation rate is 57%.Because above two kinds of daily necessitiess can only be applied to Various Seasonal, utilization ratio separately is lower.
The purpose of this utility model provides a kind of Energy-saving electric fan of both cooling and heating efficiently, and it both can be used as common electric fan, can be used as Hot-air fan at cold day again.
The purpose of this utility model is achieved in that the outer cover that has a conductive plastic to make before the electric fan fan, rib is one by one arranged on the outer cover, and there is conductive metal substrate at the two ends of rib, and conductive metal substrate is electrically connected with power supply by lead, control switch.
Fig. 1 is the front view of circular electric fan outer cover.
Fig. 2 is the front view of square electric fan outer cover.
Fig. 3 is circular electric fan stereogram.
Fig. 4 is square electric fan stereogram.
Fig. 5 is an outer cover energising schematic diagram.
As can be seen, the outer cover of this cold, hot two-purpose Energy-saving electric fan is made by conductive plastic from Fig. 1 and Fig. 2.Rib 1 one by one on the outer cover.Have between the rib 1 at interval, as the air-out path.There is conductive metal substrate 2 at rib 1 two ends, and conductive metal substrate 2 can be a metal tape, also can be wires, and two conductive metal substrates 2 are connected with lead 3 respectively, and control switch K is arranged on the lead 3, receive power supply at last.Fig. 3, Fig. 4, be that circle is an electric fan respectively, the schematic perspective view of square electric fan, the A among the figure promptly should be the outer cover among Fig. 1, Fig. 2 mutually.As can see from Figure 5, because outer cover made by conductive plastic, so each root 1 quite is a resistance R, and because of the effect of metal object 2, outer cover is equivalent to several resistance R and is connected on the power supply.After control switch K closure, rib 1 evenly generates heat, and the heat of generation is blown out by the air port, becomes hot blast.
During hot day, K switch disconnects, and this electric fan is identical with common electric fan, blows out cool breeze and uses.During cold day, the K switch closure, electric fan blows out hot blast, for people's heating.
The utility model has the advantage of:
Outer cover of the present utility model is to make with conductive plastics, and the thermal efficiency can reach more than 95%, joint About energy, the efficient height. Unsafe factor has been eliminated in the utility model flames of anger, adds conduction Frosting adopts insulation processing, safety, reliable. The utility model not only can use hot day, Also can use by cold day, accomplish dual-use material, the utilization rate height has replaced original single electric fan.
Produce the utility model, can keep the production technology and the equipment of original production electric fan producer, only need to change the part raw material.It is simple and easy to modernize and expand the existing factory, and the energy-conservation purposes of product is many.
Claims (2)
1, a kind of both cooling and heating Energy-saving electric fan is characterized in that, the outer cover that has a conductive plastic to make before the electric fan fan has rib one by one on the outer cover, and there is conductive metal substrate at the two ends of rib, and conductive metal substrate is electrically connected with power supply by lead, control switch.
2, electric fan according to claim 1 is characterized in that, conductive metal substrate is metal tape or wire.
