Abstract
The utility model provides a multipurpose electric heater, which is composed of a heating element. The utility model is characterized in that the inner of the central hole of a heat accumulation layer is provided with a heating element, and the heat accumulation layer is formed by clay sintering molding or cement prefabrication molding. The utility model can be charged to use, can also be used after preheating by energizing, and can continue with using for definite time under the condition of uncharged. The utility model has the advantages of uniform heat radiation, high utilization rate, low cost, and wide purpose, and the utility model is beneficial to human health. The utility model solves the defects that the prior electric heating equipment can not accumulate heat, and is bad for human health because of strong alternative electromagnetic field, and strong light and heat which are produced nearby the surface of heating products.
Description
The utility model belongs to warming article, says so more specifically a kind ofly to use electric heater by what electric heating element was formed more.
Existing heating product and device category are various.The heating system that with the electricity is the energy has air conditioner, electric furnace, electric blanket etc.Wherein, the air conditioner and the electric furnace that can supply many people to warm oneself simultaneously all be to utilize cross-ventilation to heat a space, and energy resource consumption is very big.Air conditioner cost height, environment for use are strict, and electric furnace has strong light and heat, heat inhomogeneous, use is dangerous, be not widely used.The environment for use of electric blanket has its limitation, and 220 volts alternating current produces stronger alternating electromagnetic field at the near surface of heating wire, and this alternating electromagnetic field is harmful to health.
Above-mentioned various heating products all have a common defective, promptly can not accumulation of heats, and just after cutting off the electricity supply, heat can not keep, and the heating effect disappears immediately.This makes troubles to the user.
The purpose of this utility model is to avoid the weak point of above-mentioned existing electricity heating product and equipment, still can continue distribute heat within a certain period of time after a kind of power cutoff is provided, thus convenient use use electric heater more.The purpose of this utility model also be to weaken owing to use AC power the heating wire near surface produce be harmful to health than strong alternating electromagnetic field.
The purpose of this utility model is realized by following scheme.
The utility model is a power supply with 220 volts of civil powers, includes electric heating element and mains switch, it is characterized in that having a recuperation layer, and this recuperation layer is by the vitrified bond moulding or adopt cement to give the type of making.There is a hole at the center of recuperation layer, places electric heating element in the hole.Electric heating element adopts internal heated type electric heated core.
Energized, electric energy is converted to heat energy by electric heating element, and this heat energy part is held in the recuperation layer that is given the type of making by vitrified bond or cement and is stayed, and cuts off the electricity supply after the uniform temperature, and its inside is held the heat that stays and is slowly distributed also thereupon and can continue the long period.
Because the existence of clay and recuperation layer has filtration for what alternating source produced on the electric heating element surface than strong alternating electromagnetic field and strong light and heat, thereby can be not harmful.
The utility model is compared prior art and is had following advantage.
1. the utility model can chargedly use, and also can cut off the electricity supply after the energising preheating, continues to use the regular hour, brings convenience to the user;
2. heating is even, the surface temperature variation is slow, uses comfortable, safe and reliable.
3. simple in structure, easy to make, with low cost.
Accompanying drawing is the utility model structural representation.
Number in the figure: 1. recuperation layer, 2. electric heating element, 3. attaching plug, 4. hole, 5. groove.
Below in conjunction with accompanying drawing, and the utility model is further described by embodiment.
Embodiment:
With 220 volts of civil powers is power supply, and electric heating element (2) is internal heated type electric heated core, for improving reliability, adopts two internal heated type electric heated core parallel connections of 20w, and mains switch adopts two grades of temperature regulating switch that have the diode halfwave rectifier.Recuperation layer (1) is by the vitrified bond moulding or adopt cement to give the type of making, and profile can be random as required, and accompanying drawing is depicted as cuboid, is of a size of 45mm * 80mm * 130mm, about 0.8 kilogram of weight.Vitrified bond or cement are being given when making type, heart position is given and is reserved the hole (4) that is used to place electric heating element (2) therein, and an end in hole is for placing the groove (5) of attaching plug (3).After recuperation layer (1) moulding, with electric heating element (2) and attaching plug (3) wiring and insert the centre bore and the groove of recuperation layer (1), insert asbestos fibre around the electric heating element (2).
During use, switched on 10 minutes, the electric heater surface temperature rises to 39 ℃ for 10 ℃ from room temperature, utilizes temperature regulating switch to realize that the normal temperature behind the temperature control is about 76 ℃, when not doing any insulation, and about 36 ℃ of the temperature of still having a surplus in back two hours of cutting off the power supply.
Electric heater is placed different places, can warm up hand, can warm up pin, also can be used as electric heating orange, electric heating incubator etc.
Claims (3)
1, a kind of electric heaters of forming by electric heating element (2) of using more, it is characterized in that having a recuperation layer (1), described recuperation layer (1) gives the type of making by the vitrified bond moulding or with cement, and there is a hole (4) at the center of recuperation layer (1), puts into electric heating element (2) in hole (4).
2, electric heater according to claim 1 is characterized in that, one end of (4) has a groove in the hole, places attaching plug (3) in the groove.
3, electric heater according to claim 1 and 2 is characterized in that, described electric heating element (2) is two internal heated type electric heated core parallel connections of 20w.
