Problems solved by technology

[0004] In the prior art, range hoods are limited by their space and layout, and there will be fumes escaping in actual use. For example, when the amount of fumes is large, fumes will escape from the bottom of the T-type machine; Side suction range hoods have the problem of fumes escaping from the top

Embodiment 1

[0079] Embodiment one: if Figure 5 As shown, when the oil fume concentration is high, the bottom of the down extension plate is 300mm away from the cooktop, the flip angle of the flip plate is 124°, the bottom extension plate is at the preset minimum position, and the flip plate is at the preset maximum flip angle. best effect.

Embodiment 2

[0080] Embodiment two: if Figure 6 As shown, when the oil fume concentration is medium, the bottom of the extension plate is 350mm away from the cooktop, the flip angle of the flip plate is 112°, the bottom extension plate is at the preset middle position, and the flip plate is at the preset middle flip angle. Medium, in this case, the cooking space is large, the influence of the range hood on the cooking staff is small, and the oil during cooking is not easy to splash on the components of the range hood.

Embodiment 3

[0081] Embodiment three: as Figure 7 As shown, when the oil fume concentration is small, the bottom of the down extension plate is 400mm away from the cooktop, the flip angle of the flip plate is 100°, the bottom extension plate is at the preset highest position, the flip plate is at the preset minimum flip angle, the concentration of oil fume is small, and the oil fume With this setting, the cooker is sufficient to absorb the cooking fume, and the cooking space is larger, so the cooker hood has less impact on the cooking staff and the cooking action.

Abstract

The invention discloses a range hood with a turnover lifting mechanism. The range hood comprises a range hood body and a smoke collecting cavity which is arranged in the range hood body, and further comprises a lower extending plate and a turnover plate, wherein a first air inlet is formed in the bottom of the smoke collecting cavity; the turnover lifting mechanism at least enables the range hoodto be in a first state and a second state; in the first state, the lower extending plate downwards extends out relative to the range hood body; the inner side of the turnover plate downwards turns over by 90 degrees or more around the outer side of the turnover plate, and the turnover plate and the horizontal plane define a non-zero included angle; in the second state, the lower extending plate retracts into the range hood body, and the turnover plate rotates to the horizontal state and covers the first air inlet; and the lower part of the lower extending plate is provided with a second air inlet which communicates with the smoke collecting cavity and faces towards a cooking area.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with a turning and lifting mechanism and a control method thereof. Background technique [0002] Cooking fumes are gases and aerosols that are gasified and decomposed by cooking oil at high temperature. Modern chemistry believes that it contains a variety of carcinogens and affects human health. [0003] Range hoods, also known as range hoods and range hoods, are usually installed above the kitchen stove, which can quickly suck away the waste generated by the stove and the harmful oil fumes generated during the cooking process and discharge them outside. [0004] In the prior art, range hoods are limited by their space and layout, and there will be fumes escaping in actual use. For example, when the amount of fumes is large, fumes will escape from the bottom of the T-type machine; Side suction range hoods have the problem of fumes escaping from the top. Contents of the ...
