Description
Technical Field
The invention relates to a side-suction type range hood.
Background
The main performance assessment index of the current range hood is air quantity, namely the exhausting capability of the oil smoke, and the other index is working noise. Often, the pair of contradictions is caused, and the range hood with large air volume drives the volute impeller to improve the air volume and the suction force by improving the rotating speed of the main motor, but simultaneously brings great noise; and the air quantity and the suction force of the range hood with smaller noise in the market are often not large. On the other hand, in the cooking process of families, one side of the kitchen range often works, the generated oil smoke is larger, the other side is less, and even no oil smoke is generated. However, the current range hood, especially the near-suction/side-suction type range hood, has a larger smoke suction surface at the panel, and the suction force at the smoke suction port closest to the lampblack is not the maximum although the air volume of the whole range hood is large and can reach 17 cubic meters/min, so that the range hood sucks more clean ineffective air.
The existing range hood also has a double-air-inlet range hood, such as a Chinese patent application with the application number of CN201410673521.3, the two air inlets realize opening/closing of the left air inlet and the right air inlet through overturning an air inlet sealing plate hinged on the back surface of a bottom plate of the smoke collecting cavity, and the opening and closing of the left air inlet and the right air inlet are uniformly realized by the air inlet sealing plate, so that the adjustment of the size of a single left air inlet or a single right air inlet cannot be realized.
