Abstract
The utility model aims at providing an electric fan capable of blowing cold wind and hot wind. The electric fan is characterized by comprising a fan body, wherein a heating assembly and a refrigerating assembly are arranged in the fan body, the outlet ends of the heating assembly and the refrigerating assembly are arranged at the fan part, and a switch for controlling the heating assembly and the refrigerating assembly is arranged on the fan body. The single use effect of the electric fan is effectively prevented, the structure is simple, and high practicability is realized.
Description
Technical field
The utility model relates to a kind of electric fan, particularly a kind of electric fan that can blow out the cold wind warm braw.
Background technology
The critical piece of electric fan is: ac motor; Its operation principle is: hot-wire coil is stressed and rotate in magnetic field.The reformulations of energy is: electric energy mainly is converted into mechanical energy, simultaneously because coil has resistance, so inevitably some electric energy will be converted into heat energy.
Indoor temperature does not only reduce, can raise on the contrary (to suppose that the room and the external world do not have heat transmission) during electric fan work.One of let us is analyzed the reason of temperature rising: during electric fan work, because the coil of electric current through electric fan arranged, lead has resistance, thus the inevitably outside heat release of generation heat, so temperature can raise.Can but why people feel wool-like fabric? Because the body surface of human body has a large amount of sweat; After electric fan worked together, indoor air can flow, so just can promote the evaporation rapidly of sweat; In conjunction with " evaporation needs to absorb great amount of heat ", it is nice and cool that old friends can feel.
And present most electric fan all can not blow out warm braw, and to enjoy the cool by electric fan mainly be to lean on the flabellum of electric fan to rotate to drive the wind that circulation of air forms.
Therefore, need a kind of electric fan that can blow out the cold wind warm braw especially, solved the problem of above-mentioned existing existence.
The utility model content
The purpose of the utility model is to provide a kind of electric fan that can blow out the cold wind warm braw, to the defective that prior art exists, has effectively prevented the unicity that electric fan uses, and the electric fan better utilization is got up, and is simple in structure, very practical.
To achieve these goals, the technical scheme of the utility model is following:
A kind of electric fan that can blow out the cold wind warm braw is characterized in that it comprises fan body, is provided with in the said fan body to heat assembly and cooling assembly, and the said port of export that heats assembly and cooling assembly is arranged on the fan place; Said fan body is provided with the said switch that heats assembly and cooling assembly of control.
In an embodiment of the utility model, the setting that crosses one another of the said port of export that heats assembly and said cooling assembly.
In an embodiment of the utility model, said switch is press button or rotates by-pass cock.
The electric fan that can blow out the cold wind warm braw of the utility model is compared with present product, electric fan can be made this performance better utilization of local air circulation; Effectively prevented the unicity that electric fan uses; Simple in structure, very practical, the purpose of realization the utility model.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the structural representation of the electric fan that can blow out the cold wind warm braw of the utility model;
Fig. 2 is the circuit diagram of Fig. 1.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
As depicted in figs. 1 and 2; A kind of electric fan that can blow out the cold wind warm braw of the utility model; It is characterized in that; It comprises fan body 100, is provided with in the said fan body to heat assembly 110 and cooling assembly 120, and the said port of export that heats assembly 110 and cooling assembly 120 is arranged on the fan place; Said fan body is provided with the said switch 200 that heats assembly and cooling assembly of control.
In the utility model, the said switch 200 that heats assembly and cooling assembly of said control is divided into three retainings.
In the utility model, said three retainings that heat the switch 200 of assembly and cooling assembly are 0 retaining, 210,1 retaining, 220 and 2 retainings 230, and described 0 retaining, 210,1 retaining, 220,2 retainings 230 correspondence respectively blow out natural wind, cold wind and warm braw.
In the utility model, said electric fan is regulated electric fan and is blown out the cold and hot of wind through controlling the said switch 200 that heats assembly and cooling assembly; What kept off for 210 last times electric fan blows out is natural wind when the said switch 200 that heats assembly and cooling assembly of control forwards 0 to; What control that the said switch 200 that heats assembly and cooling assembly forwards 220 last times of 1 retaining to electric fan blows out is cold wind, when the said switch 200 that heats assembly and cooling assembly of control forward to 2 keep off 230 last time the time warm braw that blows out of electric fan.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
