Range hood

Abstract

The invention discloses a range hood. The range hood comprises an range hood body, a draught fan and a control circuit board are arranged in the range hood body, an oil fume suction port is formed inthe range hood body, an oil filtering barrier is arranged on the oil fume suction port and comprises a frame and parallel oil filtering barrier plates arranged in the frame, the frame is in communication with the oil filtering barrier plates in a hollow mode, cooling water is arranged in the frame and the oil filtering barrier plates, at least one side of the oil filtering barrier plate is provided with an opening, an elastic rubber sheet is arranged on the opening, movable plugs are arranged on the two opposite sides of the frame, a tension spring is arranged between the movable plugs, firstinclined faces are arranged on the side faces of the movable plugs, electric push rods are arranged on the machine body, the telescopic ends of the electric push rods are connected with a hollow oil fume suction ring, oil fume suction holes are formed in the inner side ring face of the oil fume suction ring, and oil fume suction pipelines are arranged between the oil fume suction ring and the machine body. According to the range hood, the oil fume suction ring can be lifted as required, an original oil fume suction port can be automatically opened and closed in the lifting process, and the oilfiltering effect of the oil filtering barrier is better.

Description

technical field [0001] The invention belongs to the technical field of range hoods, in particular to a range hood. Background technique [0002] The range hood is a device used to remove indoor oil fume when cooking food. The range hood is generally installed above the stove, and the cooking fume is sucked by the fan suction. However, the existing range hood is generally far away from the stove, and the fan suction required is strong. The existing range hood has multiple gears. Adjust the suction power by adjusting the power of the fan, turn on the high power when there is a lot of oil fume and turn down the power when there is less oil fume. It will take a while to open after the completion, and if it is installed closer to the stove, it will affect the cooking line of sight and may cause the cook to collide with the range hood. [0003] Another example is CN103629716B which discloses a telescopic range hood with smoke ring. It comprises an annular hollow pipe, an oil su...

Problems solved by technology

However, due to the small amount of adsorption work of this kind of range hood, it is difficult to be completely absorbed in the cooking process that produces too much oil fume, so it can only be used for cooking that generates a small amount of oil fume.
