Specifically, the fan includes a motor 2023 and a wind wheel 2022, two volute case brackets 2025 are respectively fixed on a second panel on the front inner side of the case 201 and a second panel on the rear inner side of the case 201 to fix the volute case 2021, the motor 2023 is fastened in the volute case 2021 by fixing screws, the wind wheel 2022 is fixed on a rotating shaft of the motor 2023, a wind guiding ring 2024 is fixed at an air inlet of the volute case 2021 by screws, the motor 2023 drives the wind wheel 2022 to rotate so as to generate negative pressure in the case 201, that is, the motor 2023 drives the wind wheel 2022 in the volute case 2021 to rotate, an air flow rate at the volute case 2021 is accelerated so as to generate a pressure difference with the outside to form a negative pressure region, at this time, the pressure at the air inlet of the volute case 2021 is lower than the outside, and therefore, outside air enters the first air flow channel through the first air inlet and is discharged from the first air outlet.

On the basis of above-mentioned structure, as shown in fig. 8 or 9, the utility model also provides an integrated kitchen fan system, including wind channel subassembly 30 with the utility model discloses a wind cabinet subassembly, wind channel subassembly are formed with second air intake 3011, second air outlet and communicate second air intake 3011 and second air outlet's second airflow channel 3012, and the second air intake is linked together with first air outlet. Specifically, the air duct assembly comprises an air exhaust box, the air exhaust box 301 is hollow and has two open ends, a second air inlet is arranged at the top end of the air exhaust box 301 and is communicated with a first air outlet, the first end of the air exhaust box is a second air outlet, the second end of the air exhaust box is a third air outlet, therefore, when the integrated cooker fan system of the present invention is in operation, the motor 2023 drives the wind wheel 2022 in the volute 2021 to rotate, the wind flow enters the first airflow channel from the first air inlet to accelerate the air flow rate at the inlet of the volute 2021, thereby generating pressure difference with the outside to form a negative pressure area, at the moment, the pressure at the air inlet of the volute 2021 is smaller than the outside, therefore, the outside air enters the first air flow channel through the first air inlet of the volute casing via the first air inlet of the box body, then enters the second air flow channel from the second air inlet of the volute casing via the second air inlet, and finally is discharged out of the room from the second air outlet or the third air outlet.

To sum up, when the integrated stove fan system of the present invention is in operation, a part of sound wave generated by the volute component 202 in the box 201 contacts with the second panel, and the other part of the sound wave directly contacts with the sound-absorbing cotton through the sound-deadening hole 11 on the second panel and is directly absorbed; the sound wave contacted with the second panel is divided into two parts, one part is transmitted to the second panel, and the other part is reflected back; the part transmitted to the second panel is directly transmitted to the sound-absorbing cotton, and the part reflected back is continuously and repeatedly absorbed and reflected until the energy of the sound wave is consumed under the conditions of transmission and absorption by the sound-absorbing cotton; at this in-process, partial sound wave is inhaled the sound cotton and is absorbed, and another part then loss prevents the transmission of sound wave through this kind of mode, thereby makes the utility model discloses an integrated kitchen fan system reaches the effect of making an uproar when the operation.

In addition, because the air outlets of different user kitchens are different in position, as shown in fig. 9 and 10, the air deflector 302 is rotatably arranged in the second air flow channel, the switching air combing and guiding of the air outlets at the two ends of the air duct can be completed by manually adjusting the air deflector 302, and the air outlet direction of the air exhaust box 301 is adjusted to be left air outlet (second air outlet) or right air outlet (third air outlet), so that the air outlet position requirements of different user kitchens are met.

In the detailed description of the embodiments, various technical features may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The details of the foregoing embodiments are merely representative of several embodiments of the present invention, which are described in more detail and detail, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
