Embodiment 1

[0038] Embodiment 1: A method for extracting oily fume. According to the principle of typhoon, a whirlwind is generated above the worktop of the kitchen stove through a cyclone box, thereby driving the hot steam on the kitchen stove to form a strong swirling flow and extracting the oily fume.

[0039] When this method is actually applied to making range hoods, generally the equipment for generating whirlwinds is used to generate whirlwinds at different heights in the fume passage above the cooktop.

[0040] When this method is applied to oil fume extraction, try to ensure that the oil fume passage is unobstructed without obstacles, and there is no other external wind force in the oil fume passage, so as to ensure that after the whirlwind is generated, the hot steam will be driven to form a strong swirl.

[0041] The smoke exhaust ventilator that utilizes this method to make is as follows:

[0042] Such as figure 1 , image 3 and Figure 9 As shown, a range hood includes a h...

Abstract

The invention discloses a cooking fume extraction method. Cyclone is generated above a kitchen stove worktable, and hot steam above the kitchen stove is driven to form strong cyclone to extract the cooking fume by utilizing a typhoon principle. The smoke exhaust ventilator comprises a hood, wherein an cooking fume channel is formed in the middle of the hood; a cyclone box of which the middle part is the cooking fume channel is arranged on the upper part of the cooking fume channel corresponding to the hood; a first air jet hole is formed in the top of the cyclone box; a chimney is arranged above the periphery of the first air jet hole. Energy is saved, and the smoke discharging effect is good.

Description

technical field [0001] The invention relates to a range hood extraction method and a range hood. Background technique [0002] According to the current understanding, typhoons are generally formed in this way. When the temperature of the ocean water surface reaches 26.5°C or higher, as long as there is even a weak continuous swirl wind force at different heights above it, the air pressure ratio of the center of the vortex formed by the swirl wind force will The surrounding air is low, and the surrounding air carries a large amount of water vapor to the center of the vortex, and moves upward in the vortex area; the moist air rises, the water vapor condenses, and releases a huge latent heat of condensation, and the heat released by the condensation promotes the low-level air. The continuous rise promotes the further development of convective movement, causing the air pressure at sea level to drop, causing the surrounding warm and humid air to flow in and replenish, and then ri...
