Control system used for automatic start-close type bath heater

Abstract

The invention discloses a control system used for an automatic start-close type bath heater. The system is mainly formed by a control chip U, a temperature controller, a triode VT2, a polar capacitor C5, a polar capacitor C4, a voltage stabilizing diode D3, a transistor switch buffer circuit and a base electrode driving circuit connected to the control chip U, wherein an N pole of the voltage stabilizing diode D3 is connected to a VDD base pin of the control chip U and a P pole of the voltage stabilizing diode D3 passes through a resistor R8 and then is connected to an RC base pin of the control chip U; and the transistor switch buffer circuit is connected in series between the temperature controller and the control chip U. The system can control a temperature of a heating lamp of the bath heater, which means that the system can control on and off of a bath heater working current, therefore, the system is ensured to control the temperature of the bath heater. Simultaneously, the system can restrain an instant high current of an input current so that the current can keep stable, a stable driving current can be output and stability of the bath heater heating temperature is ensured.

Description

technical field [0001] The invention relates to the field of electronics, in particular, it is a control system for a self-opening and closing bathroom heater. Background technique [0002] Yuba has been widely accepted and adopted by people because of its fast heating, environmental protection, and convenient use. However, the control system of the Yuba currently used by people cannot control the temperature of the Yuba, resulting in an excessively high temperature in the bathroom, which causes people to often suffer from hypoxia due to high temperature when using the Yuba. At the same time, the existing Yuba control system still has the problem of unstable output driving current, which leads to unstable heating temperature of Yuba's warming lamp, thus affecting the service life of Yuba's warming lamp. [0003] Therefore, it is urgent to provide a Yuba control system that can not only control the temperature of the Yuba but also ensure a stable output driving flow. Conte...
