The stepless temperature regulator uses an independent control box; a potentiometer, a button, a power supply output socket, a radiator, a control circuit board, etc. are arranged in the control box. A control circuit is composed of a rectification voltage-stabilizing unit circuit, a power regulating unit circuit, a power-off protecting unit circuit, etc. The utility model has the advantages of compact structure, safe use, convenience and reliability, energy saving, electricity saving and strong load capacity, and is suitable for carrying out power change or temperature regulation to electric appliance products using electric heating elements.
Description
The utility model relates to a kind of and the supporting thermosistor of kitchen electric heating appliance.
Present commercially available common thermosistor; though energy temperature adjustment; but do not possess the power-off protection effect; in use have a power failure suddenly as civil power; the people leaves and forgets power cutoff; after restoring electricity, operatorless empty burning accident can take place in matching used with it electric heating appliance, brings dangerous often for people's lives and properties.Thermosistor present and that electric heater is supporting adopts the gear shift temperature adjustment mostly, and power regulating range is restricted.
The purpose of this utility model is to overcome the deficiencies in the prior art; design a kind of can with the supporting novel thermosistor of kitchen electric heating appliance; it has the function of stepless adjustment electrical appliance power; have the effect of electrical appliance being carried out power-off protection simultaneously, make the use of kitchen electric heating appliance safe more and convenient.
The purpose of this utility model is achieved through the following technical solutions:
A kind of stepless temperature-regulating device, it comprises:
Control box has button above it, indicator lamp, lead and attaching plug;
Control circuit, by regulator rectifier circuit, power adjusting circuit, power-off protecting circuit built-up circuit panel assembly is in the control box body
It is characterized in that:
Potentiometer W is set, start button and power output socket, potentiometer regulating handle in the upper shell of control box, the button of start button and the jack of power output socket are located at the surface of upper shell respectively, in lower house, be provided with radiator, fixing bidirectional triode thyristor on the radiator
Power adjusting circuit is by bidirectional triode thyristor BG
1, bidirectional trigger diode BG
2, potentiometer W forms, and is used to adjust the power of electrical appliance.
Power-off protecting circuit is by the DC relay J that is attempted by circuit output end of pressure-stabilizing
1Constitute.
The stepless temperature-regulating device that the utility model proposes has solved the problem that existing kitchen electric heating appliance in use carries out power adjusting and power-off protection.After adopting stepless temperature-regulating, enlarge the power adjustment of electrical appliance, played the effect of energy saving.The outage that had is protected flesh ぷ cooked food lance and is used electrical work safer, in use as unexpected power failure, and power cutoff not, must be after restoring electricity through restarting, electrical appliance could be worked, thereby has avoided operatorless empty burning accident.This thermosistor compact conformation, volume is little, and good looking appearance is safe and reliable, and load capacity is strong, is widely used in and uses the electric equipment products of heating supporting (as electric frying pan, electric chafing dish), carries out power and changes or adjustment.
