Problems solved by technology

[0002] Gas-fired stoves are suitable for field use without AC power because of their unique portability, but generally they cannot precisely control their temperature because they use gas as a heat source, so traditional thermocouples are generally used. Eternal fire is the low-cost power supply current for the electromagnetic control valve, and the precision of the mechanical temperature control device cannot guarantee the oil temperature control like a fryer. If the oil temperature is slightly higher, the oil in the oil pan may spontaneously ignite. Powered by batteries, electrical control has the disadvantages of high power consumption, and the electromagnetic control valve is not easy to shut off

Abstract

The invention relates to a low power consumption control system for a gas fryer, which includes an electromagnetic control valve, an oxygen-deficiency protection device, and a temperature control device. The temperature control device includes an electric bridge circuit, a differential linear amplifier circuit, a drive circuit, and an electric bridge. The circuit is connected to a differential linear amplifier circuit, and the differential linear amplifier circuit is connected to a drive circuit. The drive circuit is connected in series with the thermocouple of the hypoxia protection device and the coil of the electromagnetic control valve through a shut-off inductance. The temperature control device is powered by a 3V battery . The invention has high control precision and low power consumption of the control device.

Description

technical field [0001] The invention relates to a gas appliance. In particular, it relates to a low power consumption control system for a gas fryer. Background technique [0002] Gas-fired stoves are suitable for field use without AC power because of their unique portability, but generally they cannot precisely control their temperature because they use gas as a heat source, so traditional thermocouples are generally used. Eternal fire is the low-cost power supply current for the electromagnetic control valve, and the precision of the mechanical temperature control device cannot guarantee the oil temperature control like a fryer. If the oil temperature is slightly higher, the oil in the oil pan may spontaneously ignite. Powered by batteries, electrical control has the disadvantages of high power consumption and the difficulty of shutting off the electromagnetic control valve. Contents of the invention [0003] The object of the present invention is to provide a low powe...
