Abstract
The utility model discloses a positive temperature coefficient electric heating insulation plate used as an electric heating warming apparatus. The positive temperature coefficient electric heating insulation plate is composed of an upper disk and a seat, and the seat is provided with one or a plurality of positive temperature coefficient electric heating elements and added with a mains supply; one or a plurality of heat-sensitive resistance pieces (positive temperature coefficient) are arranged between two electric conduction electrode plates to form one electric heating element; the outside of the two electrode plates are added with insulated mica sheets, the outside of the mica sheets are provided with clips, and the two electrode plates are respectively connected in parallel, led out by conducting wires and connected to a power socket. The utility model has the advantages of no naked fire, long service life, elements having positive temperature coefficient, automatic temperature adjustment, energy saving, safety, and convenient use.
Description
The utility model belongs to a kind of electric heating warming device.
Employed heater has the frying pan of pan-fry beef on the present dining table, is to be fuel with coal gas, boils the chafing dish of food in addition, be to be thermal source, have following shortcoming, as being that fuel has flue dust with coal gas with these heaters with charcoal and electricity, indoor environment there is pollution, discharge a little toxic gases simultaneously, very big to people's harm, adopt electric chafing dish, can only make to boil food uses, function singleness wastes energy, and some food insulation can't be used.
For solving the deficiency of above food insulation, it is heating element with positive temperature coefficient (semistor) new material that the utility model provides a kind of, adopt plate armature, all can add gentle insulation to any food, this kind dining table heating and heat-insulating device has effectively solved heating and the insulation problem of table food, beverage.
Structure of the present utility model is achieved in that positive temperature coefficient electric heating thermal insulation dish structure is made up of base and top disk two parts, and one or more positive temperature coefficient electric heating elements are housed in base, is added with mains supply in base simultaneously.The structure of its each electric heating element is for accompanying a semistor sheet between two conductive plates, the two-plate outside is added with mica insulation sheet, each conductive plate is drawn with lead, be connected in the supply socket in the base with electric heating element two battery lead plates in all bases respectively and connect and draw.Also can be added with one or more alternate positive temperature coefficient electric heating elements between two conductive plates in base, two-plate is drawn with lead, mica sheet fixed outside above the conductive plate has the heat dissipation metal dish, two mica sheets outside voltage pole is by real, with bolted on base, this hot plate is directly powered by the civil power alternating current 220V, and the surface temperature of heat dissipation metal dish can reach 60～95 ℃.
The utility model has following advantage compared with the prior art: with the positive temperature coefficient electric heating element is heater, there are not naked light, life-span length, element itself to have the adjustment effect, outstanding feature is that caloric value is regulated automatically with ambient temperature, promptly keep temperature constant after reaching design temperature, thereby it is significantly energy-conservation, safe and reliable, simple in structure, easy to use.
Detailed structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a dish schematic diagram in garden above the positive temperature coefficient electric heating thermal insulation dish;
Fig. 2 is the positive temperature coefficient electric heating thermal insulation holder structure figure that tries to get to the heart of a matter;
Fig. 3 is the positive temperature coefficient electric heating thermal insulation dish electric heating element location drawing;
Fig. 4 is a positive temperature coefficient electric heating thermal insulation dish electric heating element structure chart;
Fig. 5 is a positive temperature coefficient electric heating thermal insulation dish power supply power supply connection layout.
Its structure is known that by Fig. 1～Fig. 5 (1) is top heat dissipation metal dish, and its surface texture shape is with to contain dish dish profile identical; (2) be base, for insulating material is made; (3) be the fixed position of electric heating element on base (2), each electric heating element structure is by shown in Figure 4, (5) and (6) be conductive plate, the centre accompanies thermosensitive resistor film (4), be added with mica sheet (9) and (10) in two-plate (5) (6) outside, add pressing plate (7) and (8) in the mica sheet outside, two-plate is drawn with lead respectively.With each conductive plate (5) and (6) respectively and connect and draw, guide on the base, its power supply is by shown in Figure 4, on base (2) mains switch is housed, power supply indicator and supply socket are because the electric heating element bidirectional switch, can divide into groups to power up control two retaining temperature.
