Intelligent range hood

Abstract

The invention discloses an intelligent range hood. The intelligent range hood comprises a machine box and an exhaust box; one side wall of the machine box is provided with an oil-fume filter assembly,the two sides of the oil-fume filter assembly are provided with oil-fume sensors; the exhaust assembly is internally provided with a fan assembly, the fan assembly comprises a motor and fan blades, one side of the motor is provided with a frequency converter control assembly, the oil-fume sensor are electrically connected with the frequency converter control assembly, and the frequency convertercontrol assembly is electrically connected with the motor; and a heating water tank is arranged at the bottom end of the inner part of the machine box. According to the intelligent range hood, the oil-fume sensors are arranged, so that the concentration of combustible gas and oil smoke can be detected in real time by utilizing the oil-fume sensors; when the oil fume concentration is high, a signalreceived by the oil-fume sensors is transmitted to the frequency converter control assembly, and the motor on the fan assembly is controlled by a frequency converter to improve the rotating speed ofthe fan assembly; and when the oil fume concentration is low, the motor is controlled by the frequency converter control assembly to reduce the rotating speed of the fan assembly, so that the energy is effectively saved, and the electricity consumption cost of a user is reduced.

Description

technical field [0001] The invention relates to the related technical field of range hoods, in particular to an intelligent range hood. Background technique [0002] The range hood is an electrical appliance used in the home kitchen to absorb the oily fume generated during cooking. The range hood is generally installed on the upper part of the stove, connected to the power supply of the range hood, and driven by a motor to make the wind wheel rotate at a high speed, so that the top of the stove will be fixed. A negative pressure zone is formed within the range of the space, and the indoor fume gas is sucked into the range hood, and the fume is filtered through the filter assembly, and the purified smoke is finally discharged along a fixed path, which can remove the waste burned by the stove and cooking. The oil fume harmful to human body produced in the process is quickly sucked away and discharged outside, reducing pollution, purifying the air, and having the function of an...

Problems solved by technology

[0004] The purpose of the present invention is to provide an intelligent range hood to solve the problem that the fan speed cannot be automatically adjusted according to the concentration of oil fume when the range hood mentioned in the above background technology is in use. When the oil fume in the kitchen increases rapidly, the existing oil fume The range hood still needs the user to manually adjust to a high-speed gear so that it can quickly remove the oil fume, which is not smart enough. Moreover, when there is little oil fume in the kitchen, the fan of the range hood still runs at high speed, resulting in a waste of electric energy. When the filter assembly is cleaned, it needs to be disassembled, which is not convenient for cleaning, and when the range hood is in use, the heat in the high-temperature flue gas cannot be recycled.
