Description
Technical field
The utility model belongs to field of electric heating, specifically relates to for example temperature adjustment electro-heat equipment of electric heater of a kind of electric heating appliance.
Background technology
Existing electric heating appliance for example electric heater all adopts the electrothermal tube heating of 220V voltage, and utilizes driving switch that a grade temperature adjustment is arranged, so the adjustment gear is few, can not carry out stepless adjustment to non-linear heater element.Especially to novel heater element--the carbon fiber heating material, because this new material far infrared heating, have wavelength and lack, advantage such as permeability is strong is widely used in the electro-heat equipment in the industrial circle.But this good exothermic material is because per unit length resistance is less, if directly add in the load with 220V voltage, the carbon fiber heating material must have enough length and power.But heat-generating pipe length is long, certainly will take more space in electric heater, the excessive application that has limited in the household appliances electric heater of power.So, people expect to invent a kind of 220V of utilization voltage, can continuously adjustable small power electric warmer electro-heat equipment with exothermic material, the temperature of carbon fiber.
Summary of the invention
The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, and a kind of continuously adjustable electro-heat equipment of temperature of function admirable is provided for electric heater.
Task of the present utility model is achieved in that the continuously adjustable electric heater electro-heat equipment of this temperature, comprises the heat-generating pipe of being made up of quartz ampoule and carbon fiber wire heater, serial connection bidirectional thyristor for regulating voltage device on the lead-out wire of carbon fiber wire one end; This silicon-controlled voltage regulation device is made up of bidirectional triode thyristor, thyristor gating circuit and rectifier diode, and wherein thyristor gating circuit comprises bidirectional trigger diode, resistance, regulator potentiometer and electric capacity.
The utility model electric heater electro-heat equipment adopts novel carbon fiber wire as exothermic material, and use the silicon-controlled voltage regulation device, carry out stepless voltage regulation, and according to the size of power demand, the carbon fiber wire of selected certain-length is made heat-generating pipe, limited the alternating current half cycle electric current heat-generating pipe of flowing through by rectifier diode, thereby limited ceiling voltage, itself and heat-generating pipe power are complementary.The deficiencies in the prior art and defective have been solved like this.As control element, have little, the noiselessness of volume with controllable silicon, circuit is simple and reliable, safety easy to use, and load capacity is strong, and the characteristics that temperature regulating range is wide make electric heater electro-heat equipment temperature adjustable continuously.
Description of drawings
Fig. 1 is the utility model structure chart.
Fig. 2 is the electrical schematic diagram of the utility model silicon-controlled voltage regulation device.
Embodiment
As shown in Figure 1, this utility model comprises the heat-generating pipe of being made up of quartz ampoule and carbon fiber wire heater 1, has been connected in series silicon-controlled voltage regulation device 2 on the lead-out wire of one end.As shown in Figure 2, this silicon-controlled voltage regulation device 2 is made up of bidirectional triode thyristor SCR, thyristor gating circuit and rectifying tube D.Wherein thyristor gating circuit comprises bidirectional trigger diode ST and current-limiting resistance R, potentiometer W and capacitor C.
When heat-generating pipe 1 (representing with FZ among Fig. 2) and silicon-controlled voltage regulation device 2 connect when exchanging 220 volts of voltages, because the rectified action of rectifying tube D, the 220V alternating current has half cycle can't flow through FZ, therefore ceiling voltage has only 110V on FZ, and the control utmost point G of bidirectional triode thyristor SCR goes up no-voltage, and SCR is in blocking-up (not conducting) state.When the in addition half cycle of 220 volts of alternating voltages charges to capacitor C through potentiometer W, resistance R, when the capacitor C both end voltage rises to blocking voltage value greater than bidirectional trigger diode ST, the ST conducting, thus make the SCR triggering and conducting, civil power is directly added on the FZ (heat-generating pipe 1).The charge constant of the trigger angle of W, R, C composition phase-shift network, SCR is by W, R, C decision among the figure, change the resistance of W, can change the trigger angle of SCR, thereby change the electric current that flows through electric heater FZ (heat-generating pipe 1), make the electro-heat equipment temperature that is contained in this electric heater adjustable continuously.
Claims (2)
1, the continuously adjustable electric heater electro-heat equipment of a kind of temperature, it comprises the heat-generating pipe of being made up of quartz ampoule and carbon fiber wire heater (1), it is characterized in that serial connection bidirectional thyristor for regulating voltage device (2) on the lead-out wire of carbon fiber wire one end.
2, the continuously adjustable electric heater electro-heat equipment of temperature according to claim 1, it is characterized in that described this silicon-controlled voltage regulation device 2 is made up of bidirectional triode thyristor SCR and thyristor gating circuit and rectifier diode D, wherein thyristor gating circuit comprises bidirectional trigger diode ST, resistance R, regulator potentiometer W and capacitor C.
