The temperature detecting probe is arranged on one end of the signal transmission line. The other end of the signal transmission line is connected with the control circuit board. The electric water heater can automatically detect temperature changes of power supply wires of users so as to control the output power of the electric water heater.
Description
Technical field
The utility model relates to the technical field of electric heater, especially is a kind of electric heater temperature sensor automaton.
Background technology
Because electric heater is a high-power electric appliance, and user's power line may not be complementary with electric heater power, cause the temperature of user's domestic power supply line to rise, so long-term, can accelerate the aging of domestic power supply line, make tame electricity consumption be in safety margin.
The utility model content
The purpose of this utility model is to provide a kind of electric heater that can detect user's power line variations in temperature with control electric heater power output automatically.
The purpose of this utility model is to realize like this.
A kind of electric heater comprises power input line, control circuit board, temperature probe and signal transfer line, and temperature probe is installed on signal transfer line one end, and the signal transfer line other end is connected with control circuit board.
The zero line or the live wire position of the corresponding domestic power supply line of the temperature probe in the technique scheme; be wrapped in zero line or the live wire insulation protective jacket outside respectively; when temperature probe detects the temperature rising of domestic power supply line; can send temperature detection signal; signal transfer line output temperature induced signal is to control circuit board; the control circuit board joint is transferred the power output of electric heater, electric heater power is reduced, to protect the safe in utilization of tame electricity consumption.
Technique scheme also can be done down further perfect: described signal transfer line and described power input line are wrapped in the insulating protective layer in the lump.
Described signal transfer line is located at the insulating protective layer outer surface of power input line, and signal transfer line and power input line are wrapped in one by decoration jointly.
The beneficial effects of the utility model are.
(1) when using electric heater; the temperature probe of electric heater can detect the temperature of user's domestic power supply line in real time; when the temperature of user's domestic power supply line rises; temperature probe can send temperature detection signal, and signal transfer line output temperature induced signal is to control circuit board, and the control circuit board joint is transferred the power output of electric heater; electric heater power is reduced; can realize the output of auto-control power, to protect the safe in utilization of tame electricity consumption, it is safe in utilization to reach protection family expenses electric wire.
When (2) implementing the temperature control detection, described temperature probe is wrapped in the insulation protective jacket outside of domestic power supply zero line or live wire.This can in time react the temperature of domestic power supply line, and the accuracy height is installed easily; Again, the power input line of the signal transfer line of described temperature probe and electric heater is wrapped in the insulating protective layer in the lump; Be easy to make and use.
