Multifunctional range hood with air curtain and air purification function

Abstract

The invention provides a multifunctional range hood with an air curtain and the air purification function. The range hood comprises a machine body and a liner plate, wherein the machine body is composed of a cooking fume collecting hood and an air duct located above the cooking fume collecting hood, the liner plate is arranged in the machine body, an air curtain draught fan is arranged on the side, close to an air duct front enclosing plate, of the top surface of the air duct, and the liner plate is in sealed connection with the top wall of the interior of the air duct and the cooking fume collecting hood so that an inner exhaust duct and an outer exhaust duct can be formed inside the machine body in a partition manner, an air outlet is formed in the cooking fume collecting hood, the innerexhaust duct communicates with the indoor space through the air outlet and the air curtain draught fan, a decorative frame is arranged on the outer side of the cooking fume collecting hood in a surrounding mode, an air guide face is arranged at the lower end of the decorative frame, and the air guide face is formed by inclining from the inner side of the decorative frame to the outer side and isused in cooperation with the air outlet. After the air curtain draught fan sucks indoor fresh air into the inner exhaust duct, air in the inner exhaust duct flows out of the air outlet and flows downwards under the action of the air guide face to form the air curtain, and therefore cooking fume on the cooking bench is prevented from diffusing to where a cook stands.

Description

technical field [0001] The invention relates to the technical field of oil fume purification devices, in particular to a multifunctional hood with air curtain and air purification functions. Background technique [0002] Range hoods are widely used in life, not only for families but also for open shopping malls or restaurants. The more commonly used top-suction range hoods on the market are usually installed directly above the cooktop, with a smoke collecting hood at the bottom and a smoke exhaust fan assembly at the top. Usually, the fume collecting hood is in the shape of a rectangle suitable for a general-purpose stove, and there is a smoking port in the middle of the bottom. After the hood is started, the oil fume flows upward from the stove under the action of the exhaust fan, and concentrates into the middle of the fume collecting hood. smoking port. As the traditional cooking methods such as frying and frying produce a lot of oil fume, and its flow tends to spread a...

AI Technical Summary

Problems solved by technology

As the traditional cooking methods such as frying and frying produce a lot of oil fume, and its flow tends to spread along the cooker to the surroundings. The chef is located in front of the stove. In order to discharge all the diffused oil fume, It is necessary to use a more powerful smoke exhaust fan, and because the chef's position is closer to the stove, some oily fumes will inevitably diffuse to the chef's position and then return to the smoke hood, which is not only harmful to the health of the chef, but also And there is a situation of oil fume escaping, which affects the air purification effect
