Exhaust system controller

Abstract

The invention relates to the technical field of kitchen exhaust energy conservation. The exhaust system controller comprises a main control unit, an infrared temperature sensor, a solid-state relay, a touch screen and a power supply. The main control unit can control the frequency of the frequency converter through output of analog signals so as to control the air volume of the fan, and the solid-state relay can control various electric appliances such as an air valve, a static machine and a water pump. The exhaust system controller monitors the temperature of each furnace end through the infrared temperature sensor, when the temperature of a certain furnace end reaches a preset value, the main control unit controls the solid-state relay to start the water pump, the static motor and the corresponding air valve and controls the frequency converter to adjust the air volume through output of analog signals, and when the temperature of the furnace end is lower than the preset value, the main control unit controls the solid-state relay to close the water pump, the static motor and the corresponding air valves and controls the frequency converter to reduce the air volume so as to achieve the energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of kitchen exhaust air energy saving, in particular to an exhaust system controller. Background technique [0002] Kitchen exhaust has developed continuously from chimneys, exhaust fans, exhaust fans, and hoods. Nowadays, commercial exhaust systems have been used in most restaurants and restaurants. The core of the system is a system with exhaust, high-voltage electrostatic ( Eliminate air oil pollution) lamp function of the cabinet (such as the Chinese patent an intelligent lampblack purifier power supply device, the lampblack purifier recorded in the patent number 201720852870.0). [0003] The disadvantage of the prior art is that the exhaust air volume is usually fixed or manually adjusted manually, and cannot be adjusted autonomously according to the actual working conditions of the kitchen. SUMMARY OF THE INVENTION [0004] In view of the deficiencies of the prior art, the present invention provides ...
