Abstract
The utility model relates to a dual-purpose electric fan for winter or summer. The electrode of a thin electric heating grid disc (1) is electrically connected with a public electrode (2) to form an electric heating unit which is arranged inside a main body of a plastic guarding-hood (3), so that the electric heating unit is integrated with a front guarding-hood of the electric fan, and without changing the surface structure, the existing electric fan is made into the utility model which can blow out the natural wind and the hot-blast. The utility model has simple structure and easy implement of production.
Description
The utility model belongs to the heat supply field.
Present known electric fan is basically by motor, the fan leaf, and several parts of front and back protective cover and support constitute.Preceding protection is covered with metal net shaped structure and plastics grid sheet trellis structure, only plays protective action.
Present known warm-air drier is basically by motor, fan leaf (or air duct), and electric heat-generating units, several parts of protective cover (or shell) constitute.The electricity heat-generating units places between fan leaf (or air duct) and the preceding protective cover (or shell), generally adopts the nichrome wire or the PTC heater of netted (or plate-like).Protective cover and electric heat-generating units are each self-separations.
Because the constraint of the electric heating material self character that is adopted, present known warm-air drier and electric fan structurally are difficult to integrate.But from use angle, the warmer of using in electric fan of using summer and winter all will collect for three seasons separately.If the unification of two things, then a thing used for two seasons, saved property, saved room space.
The purpose of this utility model is the Winter-summer dual purpose electric fan that a kind of heat-generating units of invention and preceding protective cover are integrated.
The purpose of this utility model is achieved in that the slim compound electro-thermal device that uses surface insulation makes the grid sheet of protective cover before the electric fan, makes the preceding protective cover of electric fan both play protective action, becomes surface insulation again, heating and the electric heating body of the flames of anger.Suitable electrical connection and switch control make electric fan not only can send natural wind but also can blow warm braw, Winter-summer dual purpose.
The utility model has the advantages that: a. Winter-summer dual purpose, b. is simple and practical, and c. need only transform a little to existing product, implements easily in the production.
Below in conjunction with the embodiment accompanying drawing the utility model is described further
Fig. 1 is the utility model embodiment 1: the electric heating protective cover of circular Winter-summer dual purpose electric fan.
Fig. 2 is the utility model embodiment 2: the electric heating protective cover of square Winter-summer dual purpose electric fan.
Among the figure, 1 electric heating grid sheet, 2 public electrodes, 3 plastics protective cover main bodys
In Fig. 1, the electrode of the electric heating grid sheet (1) that the slim compound electro-thermal device of surface insulation is made is electrically connected with public electrode (2), forms electric heating unit.With the electric heating unit round plastic protective cover main body (3) of packing into, and suitably fixedly become the electric heating protective cover of respective electrical fan, suitably be electrically connected the circular Winter-summer dual purpose electric fan of formation.
In Fig. 2, the electrode of the electric heating grid sheet (1) that the slim compound electro-thermal device of surface insulation is made is electrically connected with public electrode (2), form electric heating unit, with the electric heating unit square plastic protective cover main body (3) and suitably fixing of packing into, become the weak electric heating protective cover of corresponding electric wind, suitably be electrically connected and form square Winter-summer dual purpose electric fan.
Claims (1)
1, Winter-summer dual purpose electric fan is characterized in that the electric heating grid sheet (1) that the slim compound electro-thermal device of surface insulation is made is electrically connected with public electrode (2), is assemblied on the plastics protective cover main body (3), as the preceding protective cover of electric fan.
