Problems solved by technology

[0011] Also, when the flow rate of the airflow generated by the exhaust fan 6 is lower than the flow rate of the polluted air with the desired flow rate, the amount of polluted air not collected by conventional exhaust hoods will increase, and the polluted air that is sucked in substantially through the inlet The flow rate of the air is slowed down by the resistance of the filter 4
Even when the exhaust fan produces the desired flow rate to draw in the polluted air, the polluted air cannot be efficiently collected into conventional exhaust hoods, thus polluting the kitchen

Abstract

An exhaust hood is disclosed. The exhaust hood includes a body having an exhaust fan disposed at the upper side of a food preparation area and exhausting indoor air, and a filter disposed at an inlet through which the indoor air is sucked and filtering the indoor air, a wall jet generator for injecting air so as to generate a wall jet flowing along the curved surface at the front side of the body, and an air stream guide disposed a predetermined distance from the curved surface and guiding the air stream generated by the wall jet flowing to the inlet, so that the polluted air generated in thefood preparation area in the kitchen is effectively collected.

Description

technical field [0001] The present invention relates to exhaust hoods and, more particularly, to exhaust hoods including airflow directing means to effectively connect the airflows formed by the hood wall jets produced in front of the hood without dividing the airflows so that Enhanced collection of polluted air generated by kitchen food preparation areas. Background technique [0002] Generally speaking, there is a food preparation area in the kitchen, and heating devices such as electric heaters and gas stoves are placed in the area, and the food is heated and baked by heat supply to cook the food. [0003] Due to the high temperatures generated by heating devices in food preparation areas, cooking most foods will produce odors that may be in the form of oil particles or other various aerosols that disperse in the air in the kitchen, thereby irritating the nerves of those in its vicinity sense of smell. This odor is often unpleasant, in addition to being distracting and ...
