Abstract

The invention provides a flow preventing device with a cone structure, belonging to the technical field of kitchen equipment. The flow preventing device comprises a range hood, a fan, an exhaust pipe, a volume cavity, an exhaust manifold, a fixed plate and a cone, wherein an air inlet of the exhaust pipe is connected with an air outlet; an air inlet and an air outlet of the volume cavity are respectively connected with the air outlet of the exhaust pipe and the exhaust manifold; an oil collecting bottle is installed below the volume cavity; the fixed plate is arranged in the volume cavity and is fixedly bonded together with an inner wall surface of the volume cavity; the cone and through holes are formed in the fixed plate; the cone is arranged in the middle position of the fixed plate, and the through holes are formed in the marginal position of the fixed plate. Residual oil in kitchens can be collected outside the range hood by installing the cone in the volume cavity, so that the space below the range hood is cleaner.

Description

technical field [0001] The invention belongs to the technical field of kitchen equipment, and in particular relates to a flow blocking device with a pyramidal structure installed in the exhaust system of a range hood. 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 ...
