Description
Technical Field
The utility model particularly relates to a smoke ventilator spiral case.
Background
The performance of the oil fume extraction volute is directly related to the increment of the spiral line. Generally, the larger the increment of the spiral line is, the larger the exhaust air volume and the wind pressure are under the same wind speed of the wind wheel.
When the fan of the current range hood is used, the installation position of the volute is limited, and the increment of the spiral line cannot be freely increased.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned prior art, provide a can let the smoke ventilator spiral case of performance promotion of wind wheel under equal rotational speed.
The utility model discloses a smoke ventilator spiral case, including first front bezel, fourth back plate and curb plate, first front bezel, fourth back plate and curb plate connect gradually, wherein: the first front plate is provided with a second front plate, the fourth rear plate is provided with a third rear plate, the second front plate and the third rear plate are respectively inclined, one side of the second front plate and one side of the third rear plate are connected with the side plates, the second front plate is provided with an opening, the distance between the top ends of the second front plate and the third rear plate is smaller than the distance between the bottom ends of the second front plate and the third rear plate, and a through hole is formed in each side plate.
Specifically, the distance between the bottom ends of the first front plate and the fourth rear plate is equal to the bottom ends of the second front plate and the third rear plate.
Specifically, the first front plate and the second front plate are integrated.
Specifically, the fourth rear plate and the third rear plate are integrated.
Specifically, the side plates are trapezoidal in the unfolded state.
The utility model has the advantages that: this structure is the slant respectively through second front bezel and third back plate, and second front bezel and third back plate one side are connected with the curb plate, and the second front bezel is equipped with the opening, and the interval between the top of second front bezel and third back plate is less than the interval between the bottom of second front bezel and third back plate, can let the performance promotion effect of wind wheel under equal rotational speed.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 3, the utility model discloses a range hood spiral case, including first front bezel 1, fourth back plate 201 and curb plate 3, first front bezel 1, fourth back plate 201 and curb plate 3 connect gradually, wherein: first front bezel 1 is equipped with second front bezel 101, fourth back plate 201 is equipped with third back plate 2, second front bezel 101 and third back plate 2 are the slant respectively, second front bezel 101 and 2 one sides of third back plate are connected with curb plate 3, second front bezel 101 is equipped with the opening, interval between the top of second front bezel 101 and third back plate 2 is less than the interval between the bottom of second front bezel 101 and third back plate 2, be equipped with through opening 301 in the curb plate 3.
Still install wind wheel and motor in this structure, the wind wheel is connected with the motor, and the motor during operation, the wind wheel rotates and produces suction, and the air can get into from the opening of second front bezel 101, discharges from opening 301 again. Wherein this structure is the slant respectively through second front bezel and third back plate, plays to increase the increment purpose around, can let the performance promotion of wind wheel under the same rotational speed. Compared with the traditional volute, the structure can improve the exhaust air volume by 10% -20%.
One side of the second front plate and one side of the third rear plate are connected with the side plates, the second front plate is provided with an opening, and the distance between the top ends of the second front plate and the third rear plate is smaller than the distance between the bottom ends of the second front plate and the third rear plate, so that the performance of the wind wheel at the same rotating speed can be improved. Seen from the side direction, the whole body is in a trapezoidal shape, so that the gradual turning trend is formed from beginning to end, and the air flow speed is higher to improve the air exhaust amount when the air is exhausted at the rear section.
The interval between the bottom of first front bezel 1 and fourth back plate 201 is flat mutually with the bottom of second front bezel 101 and third back plate 2. In addition, the first front plate 1 and the second front plate 101 are integrated, so that the integral rigidity is improved; the fourth back plate 201 and the third back plate 2 are integrated, so that the rigidity of the whole body is improved; under the state that the side plates 3 are unfolded, the side plates 3 are trapezoidal and are better matched with the first front plate 1, the second front plate 101, the third rear plate 2 and the fourth rear plate 201 and are welded with each other.
The present invention is not limited to the above preferred embodiments, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
