Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-3, the present invention provides a technical solution:
a range hood capable of effectively reducing working noise comprises a shell 1, an oil filter screen 3 is arranged on the outer surface of the front of the shell 1, an oil collecting box 4 is arranged on the surface of the upper portion of the inner portion of the shell 1, the oil collecting box 4 is located below the oil filter screen 3 correspondingly, a control panel 2 is arranged on the front of the shell 1, a switch button is arranged on the outer surface of the control panel 2, silencing cotton plates 8 are arranged on the left side and the right side of the inner portion of the shell 1, a sound insulation plate 9 is arranged on one side, away from the shell 1, of the silencing cotton plate 8, a volute 10 is arranged in the center of the inner portion of the shell 1, a cover plate 11 is arranged behind the volute 10, a motor 12 is arranged in front of the cover plate 11, an output shaft of the motor 12 is coaxially connected with a wind wheel 13, the surface of the wind wheel 13 is treated by a Teflon coating, a pipeline 6 is connected to an outlet above the volute 10, and a check valve 15 is arranged between the volute 10 and the pipeline 6.
In this embodiment, the surface of the inner side of the control panel 2 is provided with the illuminating lamp 7, so that the lamp can be conveniently used when the light is dark.
In addition, the bend opening of the pipeline 6 is semicircular, and the turning radius is large as much as possible, so that smooth air exhaust can be ensured, the smoke exhaust effect is improved, and the noise is reduced.
Furthermore, the outside of the pipeline 6 is provided with a decorative cover 5, which is convenient for appearance.
Specifically, the oil filter screen 3 is obliquely fixed on the front outer surface of the shell 1, so that oil smoke can conveniently drop to the oil collecting box 4.
It is worth noting that the oil collecting box 4 is matched with the shell 1 in a clamping mode, and cleaning is convenient.
It is necessary to supplement that the sound attenuation cotton board 8 is made of polyester fiber fireproof material, has excellent flame-retardant and fireproof performance, is a porous material with laminated step density, has connectivity in inner holes, and generates friction with the wall of the material hole after sound enters, so that energy conversion is realized, and the purpose of attenuating sound energy is finally achieved.
It is worth to be noted that the sound insulation board 9 is formed by compounding a new high-performance material between two light boards to form a damping constraint structure, and the noise energy penetrating through the wallboard is reduced by more than 85%. When the wallboard begins to vibrate under the impact of sound waves, the polymer material in the middle of the wallboard can bear the extrusion stress and the shear stress under the action of the shear stress, and the polymer damping material in the interlayer can effectively convert the mechanical energy of the sound waves into heat energy to dissipate, so that the sound insulation effect of the wallboard is obviously improved.
When the range hood capable of effectively reducing the working noise is used, the power switch is turned on, the motor 12 drives the wind wheel 13 to rotate, so that a large amount of air is discharged from the pipeline 6, and then a negative pressure area with larger pressure difference with the surrounding area is naturally formed in the range hood shell 1 area. When the oil smoke rises, the oil smoke is attracted by the negative pressure area and enters the range hood; the oil smoke is discharged through the pipeline 6 in a circulating reciprocating mode, the check valve 15 used in the range hood belongs to a butterfly check valve, toxic waste gas and the oil smoke discharged from other households in a public flue are prevented from flowing backwards to enter the households, a power supply is closed after the range hood is used, and the range hood is used for a long time to timely clean internal oil stains and avoid influencing use.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
