Abstract
A sealed safety electric heater comprises a base (1), a heat-resistant insulating disc (2) and a heating body (6), wherein an insulating filling layer (7) is arranged on the heating body (6), a sealing cover (4) is arranged on the insulating filling layer (7), and the sealing cover (4) is matched with the heat-resistant insulating disc (2).
Description
The utility model relates to a kind of electric heater, particularly a kind of safe electric heater with heat-conducting insulation material sealing heater.
At present, electric heater has been popularized in daily life and has been used, and as directly heating or the household electrical appliance assembly, mainly contains two kinds of bareing and sealed types usually.The heater of bareing electric heater exposes, and directly contacts with air, the most commonly electric furnace, though it is it is simple in structure, cheap, easy to use, but its heater exposes, and directly contacts the work adstante febre with air, easily oxidation, aging, heating object (as soup etc.) overflow the contact heating body easily, cause its damage, its useful life is short, poor safety performance, electric shock accidents happens occasionally, the harm personal safety; The sealed type electric heater constitutes with the electrothermal tube cast aluminium, though heater does not expose, fail safe is better, and its structure is complicated, installs and uses inconvenience, and cost is higher, has increased production cost and use cost; The electric heater that also has some other types also is difficult to promote because of its complex structure.
The purpose of this utility model is a kind of improved sealed type safety electric heater that provides in order to overcome above-mentioned prior art shortcoming, and heater does not expose oxidation, aging, has both improved security performance, has prolonged useful life, has reduced cost again.
The purpose of this utility model can realize by following technical measures: this electric heater has the high temperature insulation dish, can make by refractory material, on the high temperature insulation dish, be laid with heater, heater can be heating wire, on heater, be provided with the insulation filling layer, the insulation filling layer is by heat-resisting powder filled the forming of thermal conductivity insulation, be provided with seal cover above the insulation filling layer, seal cover cooperates with the high temperature insulation dish, seal cover can be crown cap, heater, the insulation filling layer is sealed in seal cover and the high temperature insulation dish, below the high temperature insulation dish, be provided with base, base can encase the high temperature insulation dish with seal cover, and base and seal cover can bond fixing or be connected and fixed with screw, and the supply terminals of heater can be from side direction or the end to drawing.
Concrete structure of the present utility model and embodiment are provided by the following drawings.
Fig. 1 is the structure chart of sealed type safety electric heater.
Below with reference to accompanying drawing the utility model is done further auspicious stating: this electric heater has high temperature insulation dish [2], make by refractory material, can adopt existing electric furnace pan, on high temperature insulation dish [2], be laid with heater [6], heater is a heating wire, on heating wire, be provided with insulation filling layer [7], insulation filling layer [7] is by heat-resisting powder filled the forming of thermal conductivity insulation, be provided with seal cover [4] above the insulation filling layer [7], seal cover [4] cooperates with high temperature insulation dish [2], seal cover [4] can be cylinder iron or other metal make, electric furnace heating wire, insulation filling layer [7] is sealed in seal cover [4] and the high temperature insulation dish [2], below high temperature insulation dish [2], be provided with base [1], base can be metal and makes, base [1] can and seal cover [4] encase high temperature insulation dish [2], base [1] and seal cover [4] are fixing with binding material [5] bonding, the supply terminals of heating wire [3] to drawing, constitutes the very desirable sealed type safety electric heater of a heat-transfer effect from base [1] end.
The existing bareing electric heater structure of the utility model is simple, easy to install, cheap Characteristics, have again that Encapsulated electric heater security performance is good, heat transfer efficiency is high, the spy of long service life Point, and specious, be fit to promote the use of.
Claims (2)
1. sealed type safety electric heater, base [1], high temperature insulation dish [2], heater [6] are arranged, it is characterized in that being provided with insulation filling layer [7] on heater [6], be provided with seal cover [4] above the insulation filling layer [7], seal cover [4] cooperates with high temperature insulation dish [2].
2. electric heater according to claim 1 is characterized in that insulation filling layer [7] is thermal conductivity insulation powder composition.
