Range hood with oil separation function

Abstract

The invention discloses a range hood with an oil separation function.The range hood comprises an exhaust duct, a fan, a groove-shaped support, a backing plate, heat exchange oil traps, an oil storage tank, a cooling water switch and a temperature control module; the oil storage tank is movably arranged at the bottom of the groove-shaped support, the heat exchange oil traps are installed at the upper end and the lower end of the groove-shaped support through an upper fixator and a lower fixator respectively, the heat exchange oil traps comprise oil trapping tubes, the bottoms of the oil trapping tubes are communicated, the upper portions of two oil trapping tubes close to a cooling water inlet are cut off, the upper portions of other oil trapping tubes are communicated, a temperature sensor is arranged in one oil trapping tube, a cooling water outlet is connected with the cooling water switch, the temperature sensor and the cooling water switch are connected with the temperature control module, and the temperature control module controls on and off of the cooling water switch according to a signal of the temperature sensor.According to the range hood with the oil separation function, substances such as water and oil in flue gas can be recycled, and the service life of the fan can be prolonged.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood with oil separation. Background technique [0002] Most of the range hoods used in the kitchen are actually kitchen ventilators, which only have a simple ventilation function. Some of the latest range hoods have a certain function of separating oil, and the principle is collision capture. Because the catch plate, fence, mesh plate, etc. are in contact with the oily fume airflow, there is a certain temperature difference between the channel and the airflow at the initial stage, which can separate the oil from the air. However, as the use time increases, there is basically no temperature difference or a small temperature difference between the channel and the airflow. At this time, the oil in the flue gas flow is basically not separated, but is directly discharged into the atmosphere through the fan. Use this range hood mainly to have following problems: [0003...

AI Technical Summary

Problems solved by technology

[0003]1. Wasted precious oil resources and polluted the environment;

[0004]2. The flue gas flow gradually cools down during the whole exhaust process, and the fan is the end of the system with the lowest temperature, which is easy to condense or condense, especially in winter In this way, the rotation resistance will increase greatly or the motor will burn out
