Abstract
The utility model discloses a household constant temperature heating device. The device adopts a PTc positive temperature coefficient new electrical resistivity heating element as a heating part. The device also makes a heat-transfer surface be designed into a movable surface. The device can be suitable for the requirement of different constant temperature heating usage. The utility model has the advantages of low cost and high safety.
Description
The utility model relates to a kind of family expenses constent temperature heater, and particularly a kind of automatic constant-temperature heater that has adopted PTc resistive element (positive temperature rise resistance coefficient heating element is hereinafter to be referred as the PTc resistive element) belongs to household electrical appliance.
At present, home-use heater adopts the resistance wire heating more, the thermocouple electronic temperature control device, and this heater realize temperature control easily, but shortcoming is the cost height, power consumption is big, uses also inconvenient.
Task of the present utility model provides a kind of electronic circuit that need not be complicated, again can heated at constant temperature, and low cost, family expenses constent temperature heater easy to use.
The utility model is realized in the following manner:
The utility model adopts PTc positive temperature rise resistance coefficient heating element (hereinafter to be referred as the PTc resistive element) as heat generating member, input 220V line voltage, is PTc resistive element required voltage through converter with the 220V voltage transformation, the PTc resistive element at first is heated, because of having, this element can keep the substantially invariable characteristic of temperature, so work as temperature rise to certain value, the heating of PTc resistive element is given heating object by thermal conductive surface with thermal energy transfer.Thereby heating object is realized heated at constant temperature.
The PTc resistive element is designed to flat, presses with insulating heat-conduction material at bottom surface.To guarantee to conduct heat well with safe in utilization.
The selection of PTc resistive element can be determined according to the heating power needs.
Thermal conductive surface be designed to can be movable face, to adapt to the needs of different heating purposes, thermal conductive surface adopts nonmetal (as pottery) or metal heat-conducting material, adopts screw to fix.
The utility model adopts new heated at constant temperature element, and cost is low, and is safe and reliable, is fit to the multiple heated at constant temperature usefulness of family, is easy to promote.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.
Handle 1 and shell 2 adopt nonmetallic materials to process.The 3rd, supply hub, heater element 6 is the positive temperature rise resistance coefficient of a PTc heating element, be designed to flat, one side (bottom surface) of close thermal conductive surface 5 is pressed the thin mica sheet 10 with insulating heat-conductive, and thermal conductive surface 5 and 8 is two different faces, takes nonmetal or the metal heat-conducting material, thermal conductive surface 5 is made up of left and right sides two parts, during level, about dividing by magnet 7(two) adhesive is integral, at this moment can makees electric iron and use.Thermal conductive surface 5 can be boosted to overlapping with thermal conductive surface 8, and by fixed screw 4 and 9 fixing, this moment, thermal conductive surface 8 was a curved surface, can not be the object on plane easily in order to the area of heating surface, and by magnet 7 that this constent temperature heater is fixing easily with the heating object that is the iron object.
