The invention discloses a temperature-difference-driven smoke exhaust machine which comprises a temperature difference power device, a fan and a water mist oil condensing device, wherein the temperature difference power device comprises a hot cavity, a cold cavity, a cam, a piston, an air mover and a crank bar, wherein the air mover isolates the hot cavity and the cold cavity, the piston and the air mover are respectively connected with two crank shafts of the crank bar for fixation, the phase difference between the two crank shafts is 90 DEG, and the topmost end of the crank rod is connected with the cam; the water mist oil condensing device comprises a water spray device, a heat exchange device, an oil filter pipeline labyrinth and an oil storage tank, water mist sprayed by the water spray device is cooled by the heat exchange device and is mixed and in contact with high-temperature smoke in the oil filter pipeline labyrinth, and the smoke is condensed and stored in the oil storage tank; and the temperature difference power device is connected with the fan via a belt, and the fan is located in a machine shell between the temperature difference power device and the water mist oil condensing device. The temperature-difference-driven smoke exhaust machine does not require electric energy, smoke treatment can basically realize the zero emission of smoke, atomized water can reduce the adhesion of smoke to the pipe wall, the cleaning period of the smoke exhaust machine is prolonged, and convenience is provided for users.
Description
technical field [0001] The invention relates to a novel range hood, in particular to a range hood driven by temperature difference without power consumption. Background technique [0002] The range hood is a must-have household appliance in today's kitchen. It is used to exhaust the oily fumes generated during the cooking process to the outside to keep the kitchen clean. However, most of the current range hoods simply transfer the fumes from indoors to the outdoors. While polluting the atmosphere, the power consumption of range hoods runs counter to the current emphasis on energy conservation and environmental protection. [0003] At present, the fan power of the mainstream household range hood in the market is 200W, plus the lighting power, the total is 300W. However, the power of range hoods in public places such as hotels and canteens is far greater than 200W, and the working hours in public places are longer. According to this calculation, the power consumption of range...
