Therefore, the working mode of the range hood 100 can be enriched, and whether the functional component 24 is needed or not and the corresponding functional component 24 can be selected according to the working mode.

Specifically, in this embodiment, the box 12 is provided with an external circulation air outlet 48 and an internal circulation air outlet 46, and the range hood 100 can operate under an external circulation working condition or an internal circulation working condition. In the outer circulation condition, the airflow sucked by the fan assembly 14 is discharged from the outer circulation air outlet 48. Under the internal circulation working condition, the airflow sucked by the fan assembly 14 is discharged from the internal circulation air outlet 46. The first air outlet portion 50 is communicated with the air outlet 21 of the air inlet portion 18 through the second air outlet portion 52.

The case body 12 may serve as a housing of the range hood 100, and the case body 12 may be made of metal, such as stainless steel. In the illustrated embodiment, the housing 12 includes a top panel 54, a back panel 56, a front panel 58, and side panels 60, the side panels 60 including left and right side panels, the side panels 60 connecting the front panel 58, the top panel 54, and the back panel 56, and the top panel 54 connecting the back panel 56 and the front panel 58. The front plate 58 is inclined downwards from the top plate 54, and the internal circulation air outlet 46 is arranged on the front plate 58, so that air flow can be emitted upwards, and discomfort brought by direct blowing of a user is avoided.

The outer circulation outlet 48 includes an upper outlet 62 and/or a rear outlet. The upper outlet 62 may be open in the top panel 54 and the rear outlet in the rear panel 56. When leaving the factory, the upper air outlet 62 and the rear air outlet are both provided with detachable sealing plates 64.

For example, when the upper air outlet 62 is selected, the sealing plate 64 of the upper air outlet 62 can be removed, the sealing plate 64 of the rear air outlet is retained, and the smoke exhaust pipe is connected to the upper air outlet 62. When the rear air outlet is selected, the sealing plate 64 of the rear air outlet can be detached, the sealing plate 64 of the upper air outlet 62 is reserved, and the smoke exhaust pipe is connected with the rear air outlet. It is understood that in other embodiments, the outer circulation outlet 48 includes the upper outlet 62 or the rear outlet.

The first air outlet portion 50 is connected to the internal circulation air outlet 46 through an air guiding cover 66. In one embodiment, the wind scooper 66 is detachably connected to the first wind outlet portion 50, so that the matching design of the volute 16 and different wind scoopers 66 can be realized, and the requirements of different product structure sizes and different sizes of wind outlets are met, so that core components of different types of products are the same, the standardization is high, the development investment is small, the development period is fast, and the product series expansion, the performance iteration upgrade and the company operation are facilitated. The detachable connection between the wind scooper 66 and the first wind outlet 50 may be a snap connection, a screw connection, or the like.

Referring to fig. 1, 12 to 17, the range hood 100 shown in fig. 12 has a small overall structural size (e.g., a small thickness), the internal circulation air outlet 46 is small (e.g., a small width of the air outlet region), and the air outlet of the air guiding cover 66 is relatively small (e.g., a small width of the air outlet). The range hood 100 shown in fig. 14 has a large overall structural size (e.g., a large thickness), the internal circulation air outlet 46 is large (e.g., a large width of the air outlet area), and the air outlet of the air guiding cover 66 is also relatively large (e.g., a large width of the air outlet).

The range hood 100 shown in fig. 1 and 16 has a larger overall structural size (e.g., larger thickness), a larger internal circulation air outlet 46 (e.g., larger width of the air outlet area), and a relatively larger air outlet (e.g., larger width of the air outlet) of the air guiding cover 66. The thickness of the range hood 100 of fig. 16 is greater than the thickness of the range hood 100 of fig. 1.

In one embodiment, the range hood 100 of fig. 12 and 14 is small in size, the functional component 24 may not be installed, the mounting structure 22 may be installed with a cover plate 67 to shield the mounting structure 22 in appearance, so as to avoid the situation that the oil smoke enters the inside of the mounting structure 22 and is difficult to clean, and the appearance of the range hood 100 is also beautiful.

When the range hood 100 operates in the external circulation condition, gas discharged from the range hood 100 may be discharged to the outside. When the range hood 100 works in an inner circulation working condition, gas exhausted from the range hood 100 can be exhausted indoors, and at the moment, the active filtering component can be installed or not installed according to specific requirements. Fig. 18 to 20 illustrate the flow path of the airflow (smoke) when the range hood 100 is operating in the inner circulation condition, as indicated by the arrowed lines. Specifically, when the fan 26 operates, the oil smoke is sucked from the air inlet 20 of the air inlet portion 18, discharged to the second air outlet portion 52 through the air outlet 21 of the air inlet portion 18, enters the first air outlet portion 50, enters the air guiding cover 66, and is diffused to the whole internal circulation air outlet 46 by the air guiding cover 66.

In some embodiments, referring to fig. 8, a movable baffle 68 is disposed in the volute 16, and the baffle 68 is used for opening and closing the airflow channel of the first air outlet portion 50. Thus, the working condition of the range hood 100 can be selected.

Specifically, in the case that the internal circulation operating mode is selected, the baffle 68 opens the airflow channel of the first air outlet portion 50, and the airflow discharged from the air inlet portion 18 can enter the first air outlet portion 50 and then be discharged from the internal circulation air outlet 46. In the case of selecting the non-internal circulation condition (e.g., the external circulation condition), the baffle 68 closes the airflow channel of the first air outlet portion 50, the airflow discharged from the air inlet portion 18 does not enter the first air outlet portion 50, and the airflow discharged from the air inlet portion 18 can be discharged from the external circulation air outlet 48 (e.g., the upper air outlet and/or the rear air outlet) through the second air outlet portion 52.

The operating condition of the range hood 100 may be related to relevant regulations of a region or country, in addition to the user selection factor. The lampblack absorber 100 may be limited to the inner circulation condition because the lampblack cannot be discharged to the outside as specified in some regions or countries. In this case, the range hood 100 can work in the inner circulation condition by opening the baffle 68 and keeping the closing plate 64 at the outer circulation air outlet 48.

In the illustrated embodiment, the baffle 68 is rotatably disposed within the volute 16. It is understood that in other embodiments, the baffle 68 may be slidably disposed within the volute 16, or disposed within the volute 16 in a combined rotational and translational motion, and is not particularly limited herein.

In the present embodiment, referring to fig. 3, an operating member 70 is disposed outside the volute 16, and the operating member 70 is connected to the baffle 68 and is used for driving the baffle 68 to move. In one embodiment, the operating member 70 may be a lever, and is located on a lower surface of the first air outlet portion 50. The deflector rod is pulled to rotate the baffle 68, so that the airflow channel of the first air outlet portion 50 can be opened or closed. It is understood that in other embodiments, an electric drive may be used to drive the movement of the flapper 68.
