Vertical blowing and sucking type range hood

Abstract

The invention discloses a vertical blowing and sucking type range hood. The vertical blowing and sucking type range hood comprises a cooking bench, wherein an air supplementing device and a range hood are arranged on two sides of the cooking bench respectively; the air supplementing device jets airflow through an air outlet arranged on an upper end of the air supplementing device; and the range hood sucks the jetted airflow through an exhaust inlet, so that a jet flow area for entraining oil fume is formed above the cooking bench. According to the invention, oil fume and other kinds of gas harmful to human bodies, which are generated by cooking and gas combustion, can be fully entrained, and the oil fume removal efficiency is high; the air outlet and the exhaust inlet are arranged on the two sides of the cooking bench, so that normal cooking operation cannot be affected; and the jet flow area is located above the cooking bench, so that air can enter a portion below the cooking bench easily, gas is combusted sufficiently, and the situation that CO is generated due to insufficient combustion of the gas and harms cookers is avoided.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a vertical blow-suction range hood. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher requirements for a healthy and good living environment. Nowadays, there is a certain height between the range hood installed in most households and the gas cooktop, which is about 75 cm. However, the range of the range hood’s capture energy efficiency area is generally within about 40 cm below the range hood. Therefore, general range hoods cannot fully inhale oily fumes and other harmful gases produced by cooking and gas combustion, which will have a certain impact on people's health and living environment. In addition, because of the incomplete inhalation of fumes and harmful gases from the range hood and habit problems, cooks generally close the kitchen door when cooking to cut off contact with other rooms. ...

AI Technical Summary

Problems solved by technology

However, there are many disadvantages in use. During operation, human arms and various kitchen utensils will affect the effect of the air curtain, causing oily fume to overflow, and the vertical air curtain will impact downward, which is not conducive to the upward removal of oily fume, and may easily cause burns on the surface of the stove. Grease

On the other hand, the closed air flow curtain wall will greatly affect the supplement of oxygen during the combustion process, the combustion degree of the gas will decrease, and a large amount of CO will be induced, which will cause harm to the human body. At the same time, it will affect the gas requirements during the cooking process. Cause gas waste and increase the cost of daily life
