Abstract
The utility model discloses a grid-type mute range hood, which is comprised of an air duct top board, an air duct group between the air duct top board and an exhaust air box and fan system. Provided at the side of the air duct top board towards the exhaust air box is noisedamping splitter, which consists of a plurality of sound-absorbing holes with the openings inside the air duct group. Due to the noisedamping splitter provided at the inner side of the air duct top board, the sound-absorbing holes can damage the maelstroms in the space above the volute air inlet and make them into a plurality of small resonant cavities, thereby reaching the purpose of damping the noises here. Consequently, the utility model can reduce noises effectively when in work. In addition, the utility model not only cannot fail to work because of the long-term use of the range hood (oil buildup on the surface the inner part), but also adds pits on in the air duct group without effect on the air flow and air pressure.
Description
Technical field
The utility model relates to a kind of range hood.
Background technology
The lampblack absorber that uses increases day by day because of the requirement to its air quantity, blast at present, and noise is directly proportional with air quantity and blast, so noise is bigger during lampblack absorber work, though noise meets national standard, but it is generally all bigger than normal, and answer the user relative nearer with the lampblack absorber distance, the long-term use has certain noise nuisance to human body.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of grating type quiet lampblack absorber, and the quiet lampblack absorber of this grating type can effectively reduce operating noise when working.
The utility model for the technical scheme that solves its technical problem and adopt is: the quiet lampblack absorber of a kind of grating type, comprise the air channel top board, be located at the air channel group between air channel top board and the exhaust air box and be located at the interior blower fan group of air channel group, the air channel top board is provided with the noise reduction grid below exhaust air box, the noise reduction grid are made up of the sound-absorption hole that several are opened in the group of air channel.
The noise reduction grid are separated by some crisscross tablets, form several square sound-absorption hole between crisscross tablet.
Tablet is provided with several perforation, and its erasure effect of noise reduction grid of Zu Chenging is better like this.
The noise reduction grid are that the tablet of 30-40 millimeter is formed by height, and the sound-absorption hole length of side is the grid-like object of 20-40 millimeter.
The noise reduction grid are made by metal material.
The noise reduction grid are made by nonmetal.
The beneficial effects of the utility model are: because the inboard of air channel top board is provided with the noise reduction grid, sound-absorption hole on the noise reduction grid can be destroyed the maelstrom in the volute air intake vent superjacent air space, form one by one little resonant cavity, eliminate the purpose of noise herein thereby reach, so the utility model work the time can effectively reduce noise; And this example can not lose efficacy because of the long-term use (surface and inner product oil) of lampblack absorber, and increasing this example again on the air channel can not influence air quantity and blast.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is located at schematic diagram on the top board of air channel for the utility model;
Fig. 2 is located at schematic perspective view on the lampblack absorber (the blower fan group is not established the air channel group outward) for the utility model;
Fig. 3 is located at floor map on the lampblack absorber (blower fan group peripheral hardware air channel group) for the utility model.
The specific embodiment
Embodiment: the quiet lampblack absorber of a kind of grating type, comprise air channel top board 1, be located at the air channel group 3 between air channel top board 1 and the exhaust air box 2 and be located at the interior blower fan group 4 of air channel group, the air channel top board is provided with noise reduction grid 21 below exhaust air box, the noise reduction grid are made up of the sound-absorption hole 31 that several are opened in the group of air channel.
The noise reduction grid are separated by some crisscross tablets, form several square sound-absorption hole between crisscross tablet.
Tablet is provided with several perforation, and its erasure effect of noise reduction grid of forming like this is better after tested.
The noise reduction grid are that the tablet of 30-40 millimeter is formed by height, and the sound-absorption hole length of side is the grid-like object of 20-40 millimeter.
The noise reduction grid are made by metal material.
The noise reduction grid are made by nonmetal.
Again in this example, the noise reduction grid can not be fixed in below the top board of air channel, as long as at the superjacent air space of volute air intake vent the noise reduction grid are installed, the same maelstrom that destroys herein forms one by one little resonant cavity, eliminates the purpose of noise herein thereby reach.Be similarly this routine claimed scope.
