Abstract
The denoising structure of a kind of range hood, the blower fan including casing and being arranged in casing and top board, top board is that tilting is arranged on casing top, and blower fan is that tilting is arranged on top board and the axis of its axis and top board is parallel to each other.This utility model improvement by said structure, change the top board angle on casing top, thus change the angle of the blower fan being arranged on top board, making blower fan and top board is that tilting is arranged at casing internal, thus solve the deficiency relying on increasing blower fan and air box diameter and attenuating motor load rotating speed etc. to reduce noise that current range hood is simple, test proves that suction air volume and the noise-decreasing that can increase range hood significantly, when making range hood run, noise is lower, and smoke absorption effect is more preferable.It has that simple and reasonable, excellent performance, assembling be quick, low cost of manufacture, easily produce, easily realize and the feature such as safe and reliable, practical.
Description
Technical field
This utility model relates to the denoising structure of a kind of range hood.
Background technology
Smoke exhaust ventilator, also known as range hood, is a kind of kitchen appliance purifying kitchen environment, and it is arranged on kitchen health joint
Above energy range hood cooking stove, the harmful oil smoke produced in the refuse that can be burnt by cooking stove and cooking process be taken out rapidly
Walk, outside discharge chamber, reduce and pollute, purify air, and have gas defence, explosion-proof safety guarantee effect.Existing range hood is logical
Cross the high speed rotating of centrifugal wind and produce negative pressure to realize smoke pumping work, this range hood is put blower fan structure owing to being subject to
The constraint of installation dimension, the noise that the stream swirl causing centrifugal blower limited space inside air box to bring produces is inclined
Greatly, so noise is very big during work, the most practical in some field that noise is required.Meanwhile, above-mentioned noise carries to people
Carry out bigger bothering, it is suppressed significant.Traditional noise reduction schemes is dependent on strengthening blower fan and air box is straight
Footpath and attenuating motor load rotating speed etc. reduce noise, but the program not only volume, weight are big, and production cost is high, also can carry
Carry out the pressure loss, affect the performance of range hood.Therefore, it is necessary to improve further.
Utility model content
The purpose of this utility model aims to provide that a kind of simple and reasonable, excellent performance, assembling be quick, manufacturing cost
Production low, easy, easily realization and the denoising structure of safe and reliable range hood, to overcome weak point of the prior art.
By the denoising structure of a kind of range hood that this purpose designs, the blower fan that including casing and is arranged in casing and
Top board, it is characterised in that: top board is that tilting is arranged on casing top, and blower fan is that tilting is arranged on top board and its axis
It is parallel to each other with the axis of top board.
Described blower fan and top board are that the vertical line on top and the axis of the two and casing that tilting is arranged on casing forms one
Fixed angle.
Being additionally provided with filter screen and lubricating cup in described casing, filter screen is arranged on the bottom of casing, and lubricating cup is arranged under filter screen
Side.
Described casing front end is provided with control panel, blower fan and top board and towards the direction inclination of control panel and is arranged on machine
Shell top.
Described blower fan and top board are 5 °-20 ° towards the angle of inclination, direction of control panel.
This utility model improvement by said structure, changes the top board angle on casing top, thus changes and be arranged on
The angle of the blower fan on top board, making blower fan and top board is that tilting is arranged at casing internal, thus solves current range hood
The simple deficiency relying on increasing blower fan and air box diameter and attenuating motor load rotating speed etc. to reduce noise, demonstrate,proves through overtesting
Bright suction air volume and the noise-decreasing that can increase range hood significantly, when making range hood run, noise is lower, smoke absorption effect
More preferably.It has that simple and reasonable, excellent performance, assembling be quick, low cost of manufacture, easily produce, easily realize and safe and reliable
Etc. feature, practical.
Accompanying drawing explanation
Fig. 1 is this utility model first embodiment structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment.
See Fig. 1, the denoising structure of this range hood, the blower fan 1 including casing 3 and being arranged in casing 3 and top board
2, top board 2 is arranged on casing 3 top for tilting, and blower fan 1 is arranged on top board 2 for tilting and the axle of its axis and top board 2
Line is parallel to each other.
Saying further, blower fan 1 and top board 2 are arranged on the top of casing 3 and the axis of the two and casing 3 for tilting
Vertical line shape have a certain degree.
Saying further, being additionally provided with filter screen 4 and lubricating cup 5 in casing 3, filter screen 4 is arranged on the bottom of casing 3, and lubricating cup 5 sets
Put the lower section at filter screen 4.
Saying further, casing 3 front end is provided with control panel 6, blower fan 1 and top board 2 and inclines towards the direction of control panel 6
Tiltedly and be arranged on casing 3 top.
Saying further, blower fan 1 and top board 2 are 5 °-20 ° towards the angle of inclination, direction of control panel 6, and it preferably tilts
Angle is 9 °-10 °.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Ability
Territory skilled person will appreciate that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model also has
Various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model requirement
Protection domain is defined by appending claims and equivalent thereof.
