Baffle rotating type oil fume exhaust ventilator

Abstract

The invention belongs to the technical field of kitchen equipment, and relates to a baffle rotating type oil fume exhaust ventilator, which comprises an oil fume exhaust ventilator, a fan, a gas suction port, a gas outlet, a power supply switch, an illumination switch, a fan switch, a gas discharge pipe, a gas discharge total pipe, a connection pipe, a rotating shaft, a fixation plate, a rotating plate and a spring, wherein the gas inlet and the gas outlet of the gas discharge pipe are communicated, the gas inlet and the gas outlet of the connection pipe are respectively communicated with the gas outlet of the gas discharge pipe and the gas discharge total pipe, the rotating shaft is embedded on the upper wall surface of the connection pipe, the upper end surface of the rotating plate and the rotating shaft are fixedly connected, the fixation plate and the lower wall surface of the connection pipe are fixedly connected and the connection position is positioned at the upstream of the rotating plate, and the lower end of the rotating plate is connected with the fixation plate through the spring. According to the present invention, the rotating plate is arranged in the connection pipe, such that entering of the oil fume of other resident homes users into the own home can be effectively avoid; and the kitchen gas discharge system has characteristics of reasonable design and simple structure, and the indoor air pollution problem can be solved with the baffle rotating type oil fume exhaust ventilator.

Description

technical field [0001] The invention belongs to the technical field of kitchen equipment, in particular to a range hood in which a rotating plate is installed in a connecting pipe of an exhaust system. Background technique [0002] Along with the continuous improvement of living standards, people use more and more food oil when cooking, and the indoor environmental pollution produced when cooking is becoming more and more serious. In order to reduce the indoor environmental pollution when cooking, most people will install a range hood in the kitchen, turn on the range hood when cooking, and suck away the oil and gas generated during cooking. However, in most residential buildings, the range hood exhaust pipes of each household are generally connected to one exhaust main pipe, and the oil and gas of each household are sucked away by the negative pressure in the exhaust main pipe, that is, It is said that the range hood exhaust pipes of each household are all connected in par...
