Description
Technical field
The utility model relates to a kind of daily heating element, particularly thick film circuit heating element, and the utility model also relates to a kind of thick film heating electric furnace of being made by the thick film circuit heating element.
Background technology
In recent years, owing to oil, combustion gas price constantly rise violently, novel kitchen guarding's electrical equipment also more and more is subjected to consumer's welcome, and wherein electric furnace obtains people's favor especially, and the heater element that electric furnace is commonly used has heating wire, heat-generating pipe.Because heating wire or heat-generating pipe useful life are short, heating is slow, and heating wire has naked light, has hidden danger, and therefore, heater element is that the use of the electric furnace of heating wire or heat-generating pipe is restricted.
Summary of the invention
The purpose of this utility model is to provide the long and high thick film circuit heating element of heating power of a kind of life-span.
Another purpose of the utility model is to provide a kind of life-span thick film heating electric furnace long and easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: the thick film circuit heating element, comprise the chassis, on the chassis, be provided with heat-insulating shield, on described heat-insulating shield, be provided with heating board, surperficial hot setting at heating board has thick film heating circuit, and the two poles of the earth of thick film heating circuit extend to the outside of heat-insulating shield by porcelain head.
Utilize the thick film heating electric furnace of the thick film circuit heating element making of said structure, be provided with housing outside the thick film circuit heating element, the position of corresponding thick film circuit heating element forms vacancy on housing, is provided with microcrystal glass plate at the position of vacancy.
The beneficial effects of the utility model are: utilize thick film heating circuit as thermal source, greatly reduce the cost of product, also prolonged the life-span of heating element simultaneously, can reach than higher power; Thick film is generated heat circuit and heating board through hot setting together, and heat temperature raising rapidly, evenly; Therefore the thick film heating electric furnace that utilizes the thick film circuit heating element to make also has advantages such as cost is low, the life-span is long, efficient is high, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of thick film circuit heating element;
Fig. 2 is the structural representation of thick film heating electric furnace.
Embodiment
With reference to Fig. 1, a kind of thick film circuit heating element comprises chassis 5, is provided with heat-insulating shield 1 on chassis 5, the heat-insulating shield that heat-insulating shield 1 can be made by the mica opaque, the also heat-insulating shield that can be made by diatomite; Be provided with heating board 2 on heat-insulating shield 1, at the surperficial hot setting of heating board 2 thick film heating circuit 3 arranged, the two poles of the earth of thick film heating circuit 3 extend to the outside of heat-insulating shield 1 by porcelain head 6.Heating board 2 can be corrosion resistant plate or other metallic plate, it can also be non-metal board, for the ease of generating heat circuit 3 sintering together with thick film, the heating board 2 of present embodiment adopts microcrystal glass plate, because microcrystal glass plate has good insulation performance and heat conduction function, therefore, thick film heating circuit 3 is directly fixed on the microcrystal glass plate and not short circuit, can also in time thick film be generated heat circuit 3 of its heat conduction function produces heats and upwards derives, effectively having overcome thick film heating circuit 3 influences the problem in useful life because of heat accumulation, on the other hand because its heat conduction function can also effectively improve heat imitates.The bottom of heating board 2 and thick film heating circuit 3 can solidify by the high temperature sintering mode, for example: realize the curing of the two 700-900 ℃ of high temperature sintering mode.
For heating board 2 well is set on heat-insulating shield 1, on heat-insulating shield 1, form cavity, heating board 2 is placed cavity, compact conformation, stable.For the ease of the thick film circuit heating element is installed, on chassis 5, be provided with installing hole 7.
For the heating temp that guarantees heating board is no more than certain set point; between heat-insulating shield 1 and heating board 2, also be provided with thermostat 4; when the heating temp of heating board reaches certain set point; the circuit that this thermostat 4 is understood the circuit 3 that automatically thick film generated heat disconnects, and can protect thick film heating circuit 3 effectively.Thermostat 4 can be selected the bimetal leaf tempilstick, also can select the button thermostat.
With reference to Fig. 2, use for convenience, the thick film circuit heating element of said structure is made thick film heating electric furnace, being about to the thick film circuit heating element is fixed in the housing 8, position at the corresponding thick film circuit heating element in the top of housing 8 forms vacancy, is provided with microcrystal glass plate 9 at the position of vacancy, and heated object is placed on the microcrystal glass plate 9 during use, do not contact with heating board 2, easy to use.
Therefore the utility model, has advantages such as cost is low, the life-span long, easy to use owing to utilize thick film heating circuit to generate heat circuit and heating board hot setting together as thermal source and with thick film, can be widely used in various fields in life.
