Abstract
The utility model provides an electric fan capable of refrigerating and heating. A group of semiconductor chilling blades are installed behind a fan body of the electric fan, cooling fins below the semiconductor chilling blades are located in a cold and hot water tank, a radiator is installed above the semiconductor chilling blades, and a change-over switch used for changing-over between refrigerating and heating is installed on the lower portion the fan body. When the electric fan capable of refrigerating and heating is used, the change-over switch is connected with a direct-current power source, power source polarity of the semiconductor chilling blades can be changed through changing-over of the change-over switch, and therefore both the refrigerating function and the heating function are achieved.
Description
Technical field
The utility model relates to a kind of electric fan, specifically a kind of both cooling and heating electric fan.
Background technique
At present, the various electric fans of market sale and use all are the electric fans that can only blow out cool breeze, though there is in recent years the minority warm-air drier to occur, generally all have the phenomenon that function is little, power consumption is large, and the warm braw effect can't satisfy actual demand at all in the use.
Summary of the invention
The purpose of this utility model is to provide a kind of both cooling and heating electric fan, can adjust with the need, at any time and make it blowing cold air or warm braw, adapts to very much market demand.
The utility model comprises the fan body of electric fan, and the technological scheme that adopts is: described electric fan is equipped with one group of semiconductor refrigerating sheet in the behind of fan body, and the radiating fin of this semiconductor refrigerating sheet below is positioned at set hot and cold water tank; A radiator is installed above semiconductor refrigerating sheet, and the throw over switch for cold and hot switching is equipped with in the below of fan body.
The beneficial effects of the utility model are: during use, throw over switch is connected with DC electrical source, by the switching of throw over switch, can allows semiconductor refrigerating sheet change electric power polarity, two kinds of functional effects that reach thus refrigeration or heat.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is structural representation of the present utility model.
