Abstract

The invention provides a thin lampblack device with low noise, low power consumption and high efficiency, comprising fan, smoking hole, electric-control switch device for fan, oil collection box and box body. The fan is set in the box body and located at the middle. The motor for fan is motor with low noise. The main shaft of fan is vertical to the wall, namely the face of impeller is parallel with the wall. The height between top and bottom faces of box body is 40-80cm and the thickness is less than 45cm. the bottom of box body is formed by drawing. The installing height of lampblack device is 30-50cm to the highest position of kitchen eye of gas-cooker. Because the main shaft of fan is vertical to the wall the thin-type of lampblack device is realized.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] The range hoods commonly used at present are all flat cuboids, consisting of a fume collecting hood and a fan installed in the fume collecting hood. The fume collecting hood is actually made by extending the fan casing along a flat direction. This range hood is installed horizontally, so the width is relatively large, and the thickness is relatively large. In order to facilitate the operation of the cooker, it must be installed at a position higher than the height of the human body. As a result, the rising oily fume spreads before it reaches the fume collecting hood, and cannot be sucked out by the range hood, and the effect of extracting the oily fume is not very good. [0003] At present, the scheme for making the range hood thinner is: such as the application number 91105335.2 wall-mounted range hood, this patent discloses a kind of exhaust fan can be freely installed outside the ...
