Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Such as Figure 1~3 As shown, an easy-to-clean range hood according to the present invention includes, from bottom to top: long smoke hood 2, air duct support 3, top cover 6 and flue 5;

[0035] The main purpose of the long smoke hood 2 is to better gather smog; the long smoke hood 2 is equipped with an air duct support 3, a top cover 6 is installed above the air duct support 3, and a flue 5 is installed above the top cover 6;

[0036] Supporting ribs 8 are installed inside the air duct bracket 3, and the annular air duct 7 is arranged on the supporting ribs 8 in the air duct bracket 3; fans 4 are installed on both sides of the annular air duct 7; The lower end of the road 5 presses the annular air duct 7 tightly, and is fixed on the air duct support 3 with screws to ensure that excessive resonance will not occur due to the flow of the wind.

Abstract

The invention relates to a range hood easy to clean. The range hood sequentially comprises a ridge smoke hood, an air duct support, a top cover and a flue from bottom to top, supporting ribs are installed in the air duct support, and an annular air duct is placed on the supporting ribs. Fans are mounted on the two sides of the annular air duct, and the lower end of the flue tightly presses the annular air duct, so it is guaranteed that too strong resonance cannot occur due to flowing of air, then the top cover is placed, and the top cover is fixed to the air duct support. The draught fans arearranged on the two sides of the annular air duct, so the problems that draught fans in a smoke exhaust ventilator are easily stained with oil stains and not easy to clean are solved, and the servicelife of the draught fans is prolonged. Based on the principle of Coanda effect, thee flow speed of air coming out of the optimized air duct is increased, surrounding air is driven to be supplemented,and therefore generated negative pressure is used for absorbing oil smoke. An annular air duct connected with the draught fans is required to be designed so that air can be better discharged, oil smoke at the bottom can be better driven, and the cleanliness degree of the smoke exhaust ventilator is improved.

Description

technical field [0001] The invention relates to the field of kitchen and bathroom appliances, in particular to an easy-to-clean range hood. Background technique [0002] With the continuous improvement of people's living standards, the annual per capita consumption of edible oil increases rapidly, resulting in serious oil pollution of kitchen range hoods, which need to be cleaned frequently. When the oil pollution is serious, it will also affect the working efficiency of the range hood, and even affect the service life of the range hood. Existing range hoods are all powered by fans to suck the oil fume in the room, and the smoke naturally passes through the blades and the fan in the range hood, which makes the tiny oil droplets in the smoke go through the fan with the airflow. It will adhere to the fan and blades, forming oil stains, which is not only difficult to clean, but also affects the use effect of the range fume. [0003] Shortcomings of range hoods in the prior ar...
