System for controlling far infrared sauna room with self-checking function

Abstract

The invention discloses a system for controlling a far infrared sauna room with a self-checking function, which belongs to the technical field of electronic control. The system comprises an external control board, an internal control board, a switch power supply, and a power supply control board for controlling a power supply, wherein a connecting circuit of the power supply control board and a heater is connected with a current sensor for acquiring current signals, the current sensor is connected with a controller CPU in a circuit of the external control board through an amplifying circuit, the acquired current signals are amplified and then are sent to the controller CPU, and the CPU performs operation processing on the signals and then drives a speaker to give an alarm; and a control switch K is connected with a connecting circuit from the current sensor to the CPU. The system has the advantages that: after a customer finishes using and the switch is closed, if current is still input into a heating plate, the heater continues to work, and the alarm control system gives off buzzer alarm sounds to prompt the customer that the sauna room is still working and the power supply must be cut off, thus the safety after turning off of a product is ensured, the energy source is saved, and potential safety hazards such as a fire disaster and the like are avoided.

Description

technical field [0001] The invention relates to an electronic control device for a sauna room, in particular to a far-infrared sauna room control system with a self-checking function. Background technique [0002] Generally, users of small-scale far-infrared sauna steaming products will turn off the switch of the sauna room and leave the heating body directly after use. At present, most of the market uses heating plate heating methods to provide heat energy, which is a type that ignores the heat source. There is residual temperature, and it is impossible to judge whether to continue heating within a short time after the switch is turned off. The circuit board is used to control the open circuit of the power supply. When the control system is out of control and damaged, it often happens that the sauna room is found the next morning when the switch is turned off after use at night. There is still temperature inside, which causes waste to customers, and when the heating plate w...

[0002] Generally, users of small-scale far-infrared sauna steaming products will turn off the switch of the sauna room and leave the heating body directly after use. At present, most of the market uses heating plate heating methods to provide heat energy, which is a type that ignores the heat source. There is residual temperature, and it is impossible to judge whether to continue heating within a short time after the switch is turned off. The circuit board is used to control the open circuit of the power supply. When the control system is out of control and damaged, it often happens that the sauna room is found the next morning when the switch is turned off after use at night. There is still temperature inside, which causes waste to customers, and when the heating plate works for a long time, it will cause the heating plate to burn out, shorten the service life, and in severe cases, it will cause the sauna room to catch fire, causing safety hazards to customers.
