When sound enters a medium of lower refractive index from a medium of higher refractive index, if the angle of incidence is greater than a certain critical angle, the refracted sound wave will disappear and all incident sound waves will be reflected without entering a medium of lower refractive index.
The propagation speed and temperature of sound waves in air have the following relationship: As the temperature increases, the propagation speed of the acoustic wave is faster, so that the air medium with relatively low temperature is an acoustic dense medium, and the air medium with relatively high temperature is an acoustic sparse medium.
In the embodiment of the application, the sound-tight medium is air in the range hood, and a first temperature sensor is arranged in the range hood for detecting the air temperature in the range hood.
According to the embodiment of the application, the sound-dispelling medium is an air thin layer at the grille of the range hood, through the arrangement, sound waves can realize total reflection of sound and are only transmitted inside the range hood, so that the effect that the air inlet can normally intake air, but noise cannot be transmitted from the air inlet is achieved.

In an embodiment of the present application, the difference between the current pressure data p a and the first pressure data p b is less than or equal to half of the preset pressure difference k 1, which means that the current pressure data p a is closer to the first pressure data p b than the second pressure data p c. The preset power scheme corresponding to the first pressure data p b is thus selected as the preset power scheme corresponding to the current pressure data p a.
S306: and acquiring a preset power scheme corresponding to the second pressure data as the current gear data and the preset power scheme corresponding to the current pressure data.
In an embodiment of the present application, the difference between the current pressure data p a and the first pressure data p b is less than or equal to half of the preset pressure difference k 1, which means that the current pressure data p a is closer to the second pressure data p c than the first pressure data p b. The preset power scheme corresponding to the second pressure data p c is thus selected as the preset power scheme corresponding to the current pressure data p a.
S307: and controlling the power of the plurality of temperature control devices according to the current gear data and the preset power scheme corresponding to the current pressure data.
In the actual work of the range hood, the combination scheme of directly realizing heating pipe power through circuit control corresponds to a preset power scheme, so that the uniformity of the temperature of the sound-repellent medium thin layer is ensured, along with the fine fluctuation of the pressure intensity of the smoke outlet, the power combination scheme of m heating pipes is continuously regulated and controlled, the power of the heating pipes is adaptive to the pressure intensity variation, and the temperature at the grid is always kept in a stable and uniform state, and the sound-repellent medium thin layer with stable and uniform temperature is provided.
