Background technology
At present, known domestic heating product mainly contains hot-water bottle, electric blanket and electric heating hand warmer, and the temperature of hot-water bottle can not be controlled automatically, can cool off along with the decline of water temperature, and it is not lasting to be incubated; Electric blanket in use needs energising continuously, thermal energy dissipation, heat up slow, power consumption is big, and can cause user's dry skin, easily causes shortcoming such as scratch where it itches; The warming time of electric heating hand warmer is shorter again, and temperature can not realize automatic energising when reducing, and more can not realize constant temperature.
Summary of the invention
In order to solve the prior art above shortcomings, the utility model proposes a kind of electric heating device, it comprises radiator, power line and attaching plug, in radiator, be provided with one by electric hot plate, the series circuit that bimetal plate temperature controling switch and high temperature fuse constitute, the head of this series circuit, tail end connects the live wire and the zero line of power line one end respectively, another termination attaching plug of power line, electric hot plate in this sequential circuit, bimetal plate temperature controling switch and high temperature fuse adopt welding or screw ways of connecting to be installed in the inwall of radiator respectively, the utility model is simple in structure, cost is low, energy-conservation, can be switched on or switched off power supply automatically according to variations in temperature, can realize constant temperature substantially, use comfortable safety, be particularly useful for foot or the hand heating of cold season.
The utility model solves its technical problem, the technical scheme that is adopted is: a kind of warmer, comprise radiator, power line and attaching plug, its design feature is: be provided with a series circuit that is made of electric hot plate, bimetal plate temperature controling switch and high temperature fuse in radiator, the series sequence of the electric hot plate in this series circuit, bimetal plate temperature controling switch and high temperature fuse can be changed mutually, and electric hot plate, bimetal plate temperature controling switch and high temperature fuse adopt welding or screw ways of connecting to be installed in the inwall of radiator respectively.
The initial and end end of the above-mentioned series circuit that is made of electric hot plate, bimetal plate temperature controling switch and high temperature fuse is connected the live wire and the zero line of power line one end, another termination attaching plug of power line respectively.
Compared with prior art, the beneficial effects of the utility model are: owing to be provided with one by electric hot plate in radiator, the series circuit that bimetal plate temperature controling switch and high temperature fuse constitute, electric hot plate, bimetal plate temperature controling switch and high temperature fuse adopt welding or screw ways of connecting to be installed in the inwall of radiator respectively, after this sequential circuit is connected power supply, electric current flows through electric hot plate to be made its heating and heat is conducted to the heat dissipation metal body, the drive radiator heats up, owing to be in series with bimetal plate temperature controling switch in this heating circuit, it can be arranged between 40 ℃ to 60 ℃ cut-offfing temperature, when temperature is higher than 60 ℃, because thermal deformation, bimetal plate temperature controling switch disconnects, and electric current no longer flows through electric hot plate; When temperature was lower than 40 ℃, bimetal plate temperature controling switch was connected, and electric hot plate is again with energising, thereby the temperature of radiator is controlled between 40 ℃ to 60 ℃.Because the utility model also is provided with the high temperature fuse, and when the temperature that causes radiator because of fortuitous event rose to 100 ℃, the fuse of high temperature fuse promptly fused, circuit disconnects simultaneously, and temperature promptly begins to descend, thereby has guaranteed safe in utilization conscientiously.The utility model is simple in structure, cost is low, energy-conservation, can be switched on or switched off power supply automatically according to variations in temperature, can realize constant temperature substantially, use comfortable safety.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the floor map of the inner basic structure of the utility model.
Fig. 2 is the vertical section schematic diagram of the inner basic structure of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, first kind of specific embodiment of the present utility model is: a kind of warmer, comprise radiator 1, electric hot plate 2, bimetal plate temperature controling switch 3, high temperature fuse 4, power line 5 and attaching plug 6, wherein radiator 1 connects into an obturator by metal upper casing 7 and metal lower shell 8 by screw 9, inwall at radiator 1, fixed bimetal plate temperature controling switch 3, high temperature fuse 4 and two electric hot plates 2 respectively by the mode of screw attachment, wherein two electric hot plates 2 are separately fixed on the inwall of the upper casing 7 of radiator 1 and lower casing 8.This bimetal plate temperature controling switch 3, high temperature fuse 4 and two electric hot plates 2 have been formed a series circuit in radiator 1, the series sequence of the electric hot plate 2 in this series circuit, bimetal plate temperature controling switch 3 and high temperature fuse 4 can be changed mutually, the initial and end end of this series circuit connects the live wire and the zero line of power line 5 one ends respectively, another termination attaching plug 6 of power line 5.The utility model in use, attaching plug 6 is connected power supplys, and the series circuit in the radiator 1 is just switched on, and electric current flows through two electric hot plates 2 to be made its heating and heat is conducted upper casing 7 and lower casing 8 to radiator, drive radiator 1 and heat up, realize heating of the present utility model and heating function.Owing to be in series with bimetal plate temperature controling switch 3 in this heating circuit, it can be arranged between 40 ℃ to 60 ℃ cut-offfing temperature, when the temperature of radiator 1 rises to 60 ℃, because radiator 1 is directly to contact with bimetal plate temperature controling switch 3, under heat conducting effect, the temperature of bimetal plate temperature controling switch 3 also will reach 60 ℃, this moment, bimetal leaf occurred crooked because of the inconsistent of thermal deformation, thereby bimetal plate temperature controling switch 3 is disconnected, cut off circuit, electric current is no longer by electric hot plate 2, electric hot plate 2 stops heating, and the temperature of radiator 1 and bimetal plate temperature controling switch 3 just so gradually reduces, when its temperature is low to moderate 40 ℃, the thermal deformation of the bimetal leaf recovery of getting back, bimetal plate temperature controling switch 3 conductings, circuit is switched on again, and so circulation is repeatedly, thereby reach energy-conservation and effect constant temperature, guaranteed that serviceability temperature of the present utility model remains between 40 ℃ to 60 ℃.Break down or other fortuitous event occurs and when causing temperature of the present utility model to rise all the time at bimetal plate temperature controling switch 3, when temperature rises to 100 ℃, the fuse Yin Gaowen of high temperature fuse 4 and fusing, circuit disconnects, electric hot plate 2 stops heating, temperature promptly begins to descend, thereby has guaranteed safe in utilization conscientiously.
