External gas source isolation type double-energy-saving range hood

Abstract

The invention relates to the field of kitchen and bathroom electric appliances, in particular to an external gas source isolation type double-energy-saving range hood which is characterized by comprising a drawing fan, an inner air cavity and an outer air cavity. A cavity is enclosed by an inner wall of the inner air cavity, the outer side of the inner air cavity is enclosed by the outer air cavity, the periphery of the outer air cavity is isolated from the inner air cavity, and the drawing fan is communicated with the inner air cavity; the outer air cavity and the inner air cavity can be communicated with outdoor environments when the external gas source isolation type double-energy-saving range hood is used, and the drawing fan is used for drawing air to the outdoor environments. The external gas source isolation type double-energy-saving range hood has the advantages that reliable gathering and sucking effects can be realize by the external gas source isolation type double-energy-saving range hood, oil stain can be prevented from splashing, air in kitchens and rooms communicated with the kitchens can be prevented from being sucked away or disturbed, perfect cooking fume suckingeffects can be realized by the aid of the low-power fan, indoor air pressure change can be prevented, and the external gas source isolation type double-energy-saving range hood is low in noise and easy to clean.

Description

technical field [0001] The present invention designs the field of kitchen and bathroom appliances, and more specifically designs an external air source isolated double energy-saving range hood. Background technique [0002] The range hood has entered thousands of households as a household kitchen utensil and is a kitchen appliance that purifies the kitchen environment. It is installed above the healthy and energy-saving range hood stove in the kitchen. It can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. [0003] Common range hoods currently on the market suck the indoor air in the kitchen and other rooms connected to the kitchen, and the sucked air is mixed with the oil fumes produced by the kitchen range and is discharged outdoors together. Therefore, common ...

Problems solved by technology

At the same time, outdoor air enters the room through doors, windows and other parts in a compensatory manner, and electrical appliances such as air conditioners, humidifiers, and dust collectors need to work again to restore the room to the state before the normal range hood works. Must consume power and time

[0005] 2. When ordinary range hoods are working, the compensation air usually enters from the gaps in doors and windows. Usually, doors and windows have certain sealing performance. Ordinary range hoods need a large amount of air to mix with the oil fume to To suck up the oil fume, in order to increase the suction effect, the power of the fan of the ordinary range hood is getting higher and higher. In addition to its own energy consumption cost and noise, the high-power range hood further increases the cost of reprocessing the indoor air. cost

[0006] 3. When the ordinary range hood is working, the effect of oil fume extraction is not ideal; the odor of the kitchen and bathroom sewer is sucked into the room, causing the indoor odor to flood; the indoor air pressure is changed, affecting the normal opening and closing of doors and windows in the kitchen and other rooms, etc. There was a problem
