Abstract
The utility model discloses a pedal electric heating appliance which comprises a pedal part and a circuit part, wherein the pedal part comprises a shell (1), and overlapped layers (2) made of heat-insulating materials, a heating plate (3), a rubber asbestos plate (4) and a layer (6) made of insulating materials are arranged in the shell (1); the circuit part is composed of a temperature control device (5) and electric heating elements W1, W2 which are connected in series. As the utility model adopts the simple structures of the pedal part and the circuit part, the temperature of a radiating face on the surface of the pedal is uniform and is little in change, and the service life of the electric heating elements is extended. The utility model has the characteristics of simple structure, low cost and long service life, and can be used as a heating device for the feet of people.
Description
The utility model relates to a kind of electric heating installation, particularly a kind of foot-operated electric heating installation.
Existing foot-operated space heater generally all exists pedal surface uneven temperature phenomenon.When carrying out temperature control, or the temperature difference of pedal surface is bigger, or control circuit is complicated and the easy break-down that acts frequently.In addition, the service life of the heating of existing foot-operated space heater is also shorter.
The purpose of this utility model is: provide a kind of simple in structure, cost is low, the foot-operated space heater of good practical effect, long service life.
Formation of the present utility model: it comprises pedal part and circuit part; The tread portion branch comprises housing (1), it is characterized in that: adiabator layer (2), heating board (3), the rubber asbestos plate (4) repeatedly put are arranged in the housing (1); Circuit part is made of heating W1, W2 and the attemperating unit (5) that polyphone connects.
In the above-mentioned foot-operated electric heater, preferably also has an insulation material layer (6) on the described rubber asbestos plate (4).
In the aforesaid various foot-operated electric heater, described attemperating unit (5) is made of at least two temperature controller serial connections.
Compared with the prior art, the utility model has adopted better simply step part-structure and circuit structure, just makes the temperature of radiating surface of pedal surface even, and variations in temperature is little, and the heating life-span prolongs greatly.Have simple in structurely, cost is low, good practical effect, the characteristics of long service life.Can be used as people's foot heating installation uses.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Accompanying drawing 1 is structure of the present utility model and circuit theory schematic diagram;
What accompanying drawing 1 was represented is a kind of implementation of the utility model, and its formation comprises pedal part and circuit part.The tread portion branch comprises metal housing (1), is equipped with the adiabator layer (2) that is made of plastic foam on the inner base plate of housing (1), and it both can stop heat to the distributing of bottom, and the effect of strengthening electric insulation is arranged again.Be equipped with the heating board (3) of aluminium casting on the adiabator layer (2), heating W1, W2 adopt electrothermal tube, and two electrothermal tubes and heating board (3) are cast as one.Be equipped with rubber asbestos plate (4) between heating board (3) and the panel.Because the ratio of heat capacities of rubber asbestos plate (4) is bigger, has bigger thermal inertia, its counter plate can play the samming effect; When heating board (3) being carried out temperature control, the thermal inertia of rubber asbestos plate (4) can make the variations in temperature of panel surface be significantly smaller than the variations in temperature of heating board (3), give the sensation of constant temperature on the one hand, can enlarge temperature-control range on the other hand and reduce the action frequency of temperature controller, increase the service life of temperature controller.In order to increase insulation effect, should keep certain space interval between rubber asbestos plate (4) and the panel, preferably set up an insulation material layer (6).Two electrothermal tube W1, W2 and two attemperating unit (5) formations that bimetal leaf quick-action half adjusting temperature controller composes in series that circuit part is connected by polyphone, it has kept enough redundancies in the use of electrothermal tube and temperature controller.Electrothermal tube can be under very wide scope range of the fluctuation of voltage operate as normal and can not being damaged, even scaling loss can not take place yet under the situation of 380 volts of power supplys of misconnection.Electric fault can not take place in the utility model in 3 to 5 years, so service life is very long.
Claims (3)
1, a kind of foot-operated electric heater comprises pedal part and circuit part; The tread portion branch comprises housing (1), it is characterized in that: adiabator layer (2), heating board (3), the rubber asbestos plate (4) repeatedly put are arranged in the housing (1); Circuit part is made of heating W1, W2 and the attemperating unit (5) that polyphone connects.
2, foot-operated electric heater according to claim 1 is characterized in that: also have an insulation material layer (6) on the described rubber asbestos plate (4).
3, foot-operated electric heater according to claim 1 and 2 is characterized in that: described attemperating unit (5) is made of at least two temperature controller serial connections.
