Range hood and control method thereof

Abstract

The invention relates to a range hood and a control method thereof. The range hood comprises a shell and a fan system arranged in the shell, wherein a smoke inlet cavity extending vertically is formedin the lower part of the shell; a smoke inlet which communicates with the smoke inlet cavity is formed in the front side wall of the lower part of the shell; a smoke collecting cavity which communicates with the smoke inlet cavity is formed in the upper part of the shell; the smoke collecting cavity extends forwards to form an installation cavity used for installing the fan system; an air inlet of the fan system communicates with the smoke collecting cavity; and a first lighting assembly for lighting downwards is arranged at the bottom of the installation cavity. The rear wall of the shell ofthe range hood is hung on the wall, the smoke inlet cavity can extend downwards to be sufficiently close to a kitchen range and an oil smoke generating source due to the fact that the smoke inlet cavity at the lower part of the shell vertically extends, then oil smoke is rapidly sucked into the smoke inlet cavity to be exhausted upwards as soon as the oil smoke is generated, and the effect of sucking the oil smoke is improved; and according to the appearance of the range hood, the first lighting assembly arranged at the bottom of the installation cavity can realize direct lighting, the lighting effect is improved, and convenience is provided for users.

Description

technical field [0001] The invention relates to a range hood and a control method thereof. Background technique [0002] The range hood is an indispensable electrical appliance in the kitchen at present, the more common and widely used is the upper exhaust fume purification system. [0003] At present, the upper exhaust fume purification system is mainly divided into two categories: top suction range hood and near suction range hood. The top-suction range hood is more beautiful, but its smoke inlet is higher, and the range hood effect is limited; Due to the influence of the shape structure of the range hood and the structure of the internal air duct, the current near-suction range hood cannot get closer to the range hood, which limits its range hood effect to a large extent. [0004] In addition, when cooking at night, it is often impossible to clearly observe the cooking situation because the lighting angle of the kitchen cannot be concentrated on the stove. In order to ...

AI Technical Summary

Problems solved by technology

The top-suction range hood is more beautiful, but its smoke inlet is higher, and the range hood effect is limited; Influenced by the shape structure of the range hood and the internal air duct structure, the current near-suction range hood cannot get closer to the range hood, which limits its range hood effect to a large extent.

[0004] In addition, when cooking at night, it is often impossible to clearly observe the cooking situation because the kitchen lighting angle cannot be concentrated on the stove

In order to solve this problem, existing range hoods already have structures equipped with lighting fixtures. However, for range hoods that can be in close contact with the range hood, it is difficult to install a direct-type effective lighting structure due to the limitation of the shape. , leading to poor lighting effect and unable to meet consumer demand
