Abstract
The utility model relates to a directly-heating type electric heating plate with constant temperature. An outer shell is composed of a base plate and an upper cover, and a heating resistor is arranged in the outer shell. The heating resistor is a PTC heating element with the constant temperature, the upper and the lower two sides of the heating element are provided with an upper electrode plate and a lower electrode plate, and Mica insulating pieces are arranged between the upper and the lower electrode plates, the base plate and the upper cover. The utility model is directly arranged in a container, an upper cover is generally used as the bottom of the container to reach direct heating, and the utility model can be made into devices such as an electric heating cup, an electric heating kettle, an electric heating pot, an electric heating tank, etc. The temperature of the PTC heating element with the constant temperature can be made according to requirements, and the directly-heating type electric heating plate with the constant temperature is especially suitable for the electric heating cup with 12v-24v electric voltage of an automobile cab.
Description
The utility model relates to electric hot tray, can match with containers such as cup, kettle, chafing dish, middle medicinal cuppings, makes in the electric cup, electric kettle, electric heating chafing dish, electric heating of the various different voltages of 12V～220V medicinal cupping or steam beauty care device etc.
Existing electric cup, electric kettle or electric chafing dish etc., the major defect of its existence has two aspects, and the one, the employing resistance wire is a heating resistor, temperature control is poor; The 2nd, be generally indirect, the heat efficiency is low.
The purpose of this utility model is that designing a kind of is heating resistor with the thermostatic element, and heating plate is installed in the directly-heated type heating plate in the container.
The technical scheme of the utility model directly-heated type constant temperature electric heating plate is: be made up of institutes such as chassis, loam cake and heating resistors, its so-called heating resistor is the PTC constant temperature heating element, heater element upper and lower electric pole plate and lower electrode plate are arranged, between battery lead plate and chassis and the loam cake insulating trip is arranged.
Directly-heated type constant temperature electric heating plate of the present utility model has the fixed head of insulating material at the edge of PTC constant temperature heating element and battery lead plate.
The lead that the utility model directly-heated type constant temperature electric heating plate, its connection are pressed battery lead plate passes through sealing plug, lead joining power in the exit on chassis.
The utility model discloses a kind of directly-heated type constant temperature electric heating plate, is heating resistor with the PTC constant temperature heating element, compared with the prior art, have Controllable Temperature, long service life, and be installed in the container medium is directly heated, heat efficiency height, disassembly, cleaning are convenient.
Fig. 1 is the utility model directly-heated type constant temperature electric heating plate structural representation.
Below in conjunction with Fig. 1 embodiment of the present utility model is done detailed explanation.
1. loam cake; 2. insulating trip; 3. chassis; 4. insulating trip; 5. sealing ring; 6. hold-doun nut; 7. screw; 8. lead; 9. lower electrode plate; 10. fixed head; 11.PTC constant temperature heating element; 12. last electroplax plate; 13. base; 14. container; 15. sealing plug.
The utility model relates to PTC constant temperature heating element 11 as resistance, temperature can be controlled according to design, on PTC, electric pole plate 12 and lower electrode plate 9 arranged, mica insulation sheet 2,4 is arranged outside battery lead plate, insulation fixed head 10 is arranged, the chassis 3 and the loam cake 1 that have stainless steel to make outside around PTC and battery lead plate.Upper and lower battery lead plate is a conductive plate, again as heating panel, lead 8 joining powers is arranged.Chassis 3 is fixed by screw 7, nut 6 with container 14 or base 13, and sealing plug 15 is arranged in the screw, and lead is drawn joining power through sealing plug, and sealing ring 5 is arranged.Whole electric heating plate is installed in the container 14, materials such as liquid is directly heated as container bottom with loam cake, and base 13 is arranged down.This heating plate is specially adapted to make driver's electric cup, utilizes driver's cabin power supply 12V～24V voltage.
