Near-suction-type range hood and control method of range hood

Abstract

The invention relates to a near-suction-type range hood. The near-suction-type range hood comprises a shell, an air inlet plate, an oil fume baffle, a sensor detection module and a first driving mechanism, wherein the front side of the shell is provided with an opening; the air inlet plate is arranged in the opening position of the shell, and an air inlet is formed in the air inlet plate; the oil fume baffle is rotatably connected with the shell, and can close and open the air inlet; the sensor detection module is used for detecting concentrations of oil fume and / or water vapor at the front side of the shell; and a power output end of the first driving mechanism is connected with the oil fume baffle, and the oil fume baffle can be driven to be opened and kept in an angle state which matches the concentrations, detected by the sensor detection module, of the oil fume and / or the water vapor. According to the range hood, an opening and closing angle of the oil fume baffle can be dynamically adjusted by the oil fume baffle according to the oil fume condition, so that an oil fume suction effect is effectively improved. The invention further relates to a control method of the range hood.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a near-suction range hood and a control method for the range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top suction type and near (side) suction type. The side suction type range hood uses the principle of eddy current wind pressure to absorb most of the oil fume close to the stove in the form of an arc, which can reduce the impact on the human body. Health adverse effects, and the power source is closer to the stove, basically will not reduce the suction effect of the power source. [0003] For example, the Chinese utility model patent with the application number CN201921395296.6 (the authorized announcement number is CN211119558U) discloses "A Side-suction Range Hood", which includes a shell with an opening on the front side, and is set at the opening on the fron...

Problems solved by technology

[0004] The side-suction range hood in the above patent still has certain deficiencies in the actual use process. First, after the range hood is installed, the rotation position of the smoke baffle is fixed, that is, the smoke baffle is opened. The angle position is fixed and cannot be dynamically adjusted according to the actual situation of the oil fume. Therefore, there is a risk of oil fume escaping; moreover, even if the opening and closing angle of the smoke baffle can be dynamically adjusted according to the actual situation of the oil fume, the oil fume detection The sensor generally waits for the oil fume to rise to the top air inlet before giving the detection result. When the range hood is initially used, if the oil fume rises and then greatly adjusts the opening and closing angle of the baffle, it is too late, and the oil fume still remains. There is a greater risk of escape
