Timing power adjuster for electric heating

Abstract

The invention discloses a timing power adjuster for electric heating. The timing power adjuster comprises a power plug, a three-core power wire, an electric appliance socket, a power selector switch, a time selector switch, a work switch, a 24V current-limiting rectifier, a 10-gear adjustable vibrator, a 12V voltage stabilizing circuit, a 3-gear adjustable timer, a power and timing signal aggregator, a relay and a matcher circuit. According to the timing power adjuster, an electric heater acquires the electric energy accounting for 10-100% of self rated power in a manner of continuously and intermittently supplying power by the controlled relay, so that the temperature is adjusted, and the 3-gear adjustable timer and the time selector switch are used for ensuring that the power supply for the electric heater is stopped when a preset time of work is up.

Description

technical field [0001] The invention relates to a timing power regulator for an electric heating appliance, in particular to a timing power regulator for controlling the temperature of a household electric heating appliance such as an electric soldering iron with a rated power below 2200W through power regulation and supplying power at a preset time. Background technique [0002] Electric heating appliances such as electric soldering irons and electric cooking utensils have the best performance only when the temperature matches the on-site working environment. This requires that electric heating appliances must have multiple power levels to meet different electric heating requirements. For example, for soldering electric irons, too high a temperature will cause the iron tip to form an oxide skin that is difficult to conduct heat and repel the solder, which not only reduces efficiency but also wastes energy; for electric cookers, it is necessary to provide different temperatur...

AI Technical Summary

Problems solved by technology

For example, for soldering electric irons, too high a temperature will cause the iron tip to form an oxide skin that is difficult to conduct heat and repel the solder, which not only reduces efficiency but also wastes energy; for electric cookers, it is necessary to provide different temperatures to meet the needs of different food groups. Heating Process Requirements

General household dynamometers have a narrow scope of application and high cost. In addition, in the process of use, the electric heating appliances cannot be cut off in time, resulting in energy waste and even accidents.
