Abstract
The utility model discloses an energy-saving constant temperature electric heater, belongs to an electric heating device, and aims to provide the electric heating device with automatic constant temperature, good security, low power consumption and long service life. The energy-saving constant temperature electric heater comprises a box body and at least one electric heating device arranged in the box body, wherein the electric heating device consists of two heat radiators fixed at the bottom of the box body (1) and a plurality of PTC (Positive Temperature Coefficient) ceramic thermistor pieces (7) clamped between the two heat radiators; each heat radiator consists of two heat radiator bodies (4) and a heat radiation strip (6) fixed in the bodies; and the two heat radiators form a loop through a temperature regulating device (5) electrically connected with the two heat radiators, and a pedal grate plate (2) fixed in the box body (1) is arranged above the electric heating device. With the adoption of the energy-saving constant temperature electric heater, the defect that the electric heating element is easy to oxidize to be damaged is overcome, therefore, the energy-saving constant temperature electric heater has the advantages of simple structure, safe use, good heating effect and the like, and is an electric heating device suitable for large numbers of families.
Description
Technical field: the utility model relates to a kind of heating installation, relates in particular to a kind of electrothermal heating apparatus.
Background technology: electric heating device is accepted by increasing consumer because of having plurality of advantages such as cleaning, health, convenience.At present, the various electric heating devices of extensively selling all are to be heater element with quartz ampoule or resistance wire on the market, and not only power consumption is big, oxidation and damaging easily, and because temperature is uncontrollable, exist Yin Wendu too high and cause burn and scald or disaster hidden-trouble, security is relatively poor.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aim to provide a kind of can the automatic constant temperature, the energy-conservation constant temperature electric heating warmer of good, the little power consumption of security, long service life.
To achieve these goals, the utility model is by the following technical solutions: it comprises the uncovered casing in top, is located at least one electric calorifie installation in this casing, described electric calorifie installation is made of two radiators that are fixed on bottom half by support, a plurality of PTC ceramic thermal resistance sheets of being clamped between described two radiators, described radiator by the radiator body of two rectangular box-like structures, be folded into the heat-radiation belt that laciniation is fixed in this body and constitute; Two radiators form the loop by the temperature-adjusting device that is electrically connected with it, and the step grate plate that is fixed in the casing is arranged above electric calorifie installation.
Heat sink strip is the rectangle frame structure, is fixed with the heat-radiation belt that is folded into laciniation in this rectangle frame; The back side at step grate plate is fixed with protection network.
Compared with the prior art, the utility model is owing to adopted technique scheme, PTC ceramic thermal resistance sheet with middle low temperature substitutes traditional high-temperature electric heat elements such as quartz ampoule or resistance wire, therefore not only eliminate the too high and many potential safety hazards brought of temperature effectively, improved safety in utilization, but also overcome the easy oxidation of high-temperature electric heat element and the defective damaged, prolonged service life greatly; In addition, owing to adopted the radiator that is provided with the zigzag heat-radiation belt, therefore increase heat exchange area significantly, improved radiating effect effectively, thereby reached the purpose that improves heating effect, reduces electric calorifie installation self temperature, further strengthened safety in utilization.
