Abstract
The utility model provides an automatic limiting and control temperature electrothermal board, composed of an insulation face board 1 or a face board 1 which is treated through insulation, a coating type electrical heat generation film 2 which is coated on the lower surface of the face board, a conductive electrode 3, insulation thermal-protection material 4, a supporting board 5, a thermostat 6, a frame 7, a control circuit 8 and a conducting wire 9. The utility model adopts the electrical heat generation film to be as a heat generation element. The utility model has the advantages of temperature automatic limiting, no glowing, no flame, ageing resistance, long service life, fast temperature rising, low cost, high thermal efficiency, safety and electricity saving, and can be widely suitable for heating on the table top or at the feet in the places such as the family, the school, the hospital, the office, etc.
Description
The utility model relates to the home-use electric heating appliance field, and relevant with electrothermal film technology, coating technology.
Existing electric heating plate, disclosed adjustable electric heating table glass of for example Chinese utility model patent communique CN2053000u and the disclosed temperature self-controlled electric platen of CN2084701u, by the metallic resistance silk of clamping between panel and the base plate as heating element heater, has certain heating ability, not enough then is that well-known metallic resistance wire connection energize is promptly rubescent, easy oxidation fracture of wire, cause accidents such as fire easily, the uneven defective of generating heat in addition, if adopt the glass material panel, the inhomogeneous glass sheet breakage that causes easily of being heated, the service life of product is short, especially can produce stronger electromagnetic field human body is produced harm, China has drawn up the national standard of " electric blanket (plate) electromagnetic field intensity limit value ", and prior art is difficult to reach the regulation of this standard.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, designing a kind of is heating element heater with the Electric radiant Heating Film, have quick heating, the flames of anger, ageing-resistant, the life-span is long, cost is low, the thermal efficiency is high, be the face heating, be no more than 100V/m from limit temperature control temperature, electromagnetic field intensity, safe and reliable electric heating plate is as desirable heating system in winter.
Feature of the present utility model is that the lower surface at panel 1 is coated with one or more layers coating type electric heating film 2, at the edge, two ends of heating film 2 bonding top electrode 3, extracting power supply cord 9, evenly spread its insulating heat insulating material 4 of cloth, load onto supporting plate 5, frame 7 is installed, and thermostat 5 is close on the power line that is serially connected with on the panel 1 any part surface between electrode 3 and the control circuit 8, promptly gets of the present utility model from limitting temperature control temperature electric heating plate.
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is further described:
Fig. 1 is a structure cross-sectional schematic of the present utility model, 1-panel wherein, and 2-coating type electric heating film, the 3-conductive electrode, the 4-insulating heat insulating material, the 5-supporting plate, the 6-thermostat, the 7-frame,
Fig. 2 is a floor map of the present utility model, 8-control circuit wherein, 9-power line.
The temperature control of the limit certainly temperature electric heating plate that the utility model provides, overcome the harm of electromagnetic field to human body, security, durability have been strengthened, proportioning that can be by adjusting the coating type electric heating film and select the thermostat kind to realize from limitting the temperature control temperature will be safe and reliable with it, good and cheap, be well received.
Claims (6)
1, a kind of from limitting temperature control temperature electric heating plate, mainly form by panel 1, supporting plate 5 and frame 7, it is characterized in that between panel 1 and supporting plate 5, be coated with the lower surface of one or more layers electric heating film 2 at panel 1, the end edge that conductive electrode 3 sticks on the upper surface opposition of the lower surface of panel 1 or Electric radiant Heating Film 2 closely contacts and draws lead 9 with Electric radiant Heating Film 2, evenly shop cloth insulating heat insulating material 4, and thermostat 6 is serially connected on the power line 9 between conductive electrode 3 and the control circuit 8 and the temperature-sensitive face of thermostat is closely contacted with panel 1.
2, electric heating plate according to claim 1 is characterized in that said panel 1 is insulation or the nonmetal or sheet metal handled well through insulation.
