The range hood embodiment 1 provided by the invention comprises an oil cup 4, a smoke collection cavity 5, a control panel, a decorative cover 7, a shell 8, a fan, a filter assembly and a driving device, and is shown in figures 1 to 4. Fig. 1 is a front view of the hood, fig. 2 is a bottom view of the hood, fig. 3 is a right side view of the hood, and fig. 4 shows the hood without the oil cup 4 installed. The control panel is arranged above the smoke collecting cavity 5, and a human-computer interaction interface 6 is arranged on the control panel. The fan is arranged in the shell 8, and the decorative cover 7 is covered outside the shell 8.
The filter assembly is placed in the smoke collection chamber 5. The smoke collection chamber 5 is arranged obliquely with the front higher and the back lower, as shown in fig. 3, the point a in fig. 3 represents the "front" end of the smoke collection chamber 5, and the point B in fig. 3 represents the "back" end of the smoke collection chamber 5. The inclination angle of the smoke collection cavity 5 is 15 degrees, that is, the angle between the horizontal plane and the connecting line between the points a and B in fig. 3 is 15 degrees, that is, the angle between the edge contour line of the smoke collection cavity 5 and the horizontal plane is 15 degrees. Therefore, the integral shape of the range hood is between that of a top-suction range hood and that of a side-suction range hood, so that the function of the filtering component is conveniently exerted, and the collection of grease attached to the filtering component is facilitated. The oil cup 4 is positioned at the lowest end of the smoke collection cavity 5. The oil cup 4 comprises a rear wall and an air guide surface which is arranged in an inclined manner with a high front part and a low rear part, the rear wall is connected with the air guide surface, and an included angle between the rear wall and the air guide surface is an acute angle.
The filter assembly comprises two movable smoke guide plates 1 and a plate body part 2 positioned between the two movable smoke guide plates 1, wherein the two movable smoke guide plates 1 are arranged and suitable for moving under the driving of a driving device. The filter assembly is arranged and adapted to be switched between a first mode and a second mode by moving the two movable smoke guide panels 1. When the filter assembly is switched between the first mode and the second mode, the two movable smoke guide plates 1 respectively rotate around a rotating shaft. The "rotation shaft" is inserted through the corresponding movable smoke guide plate 1 along the front-back extension direction of the corresponding movable smoke guide plate 1. The driving device comprises two motors, the two motors are in one-to-one correspondence with the two movable smoke guide plates 1, and the motors drive the rotating shafts of the corresponding movable smoke guide plates 1 to rotate so as to enable the corresponding movable smoke guide plates 1 to rotate. Preferably, the two movable smoke guide plates 1 rotate synchronously. The two movable smoke guide plates 1 are the same in size and shape.
The plate member 2 is removably mounted in the smoke collection chamber 5 and the plate member 2 is stationary when the filter assembly is switched between the first mode and the second mode. Specifically, the plate body 2 is a filter screen, and the edge profile of the outer surface of the plate body 2 is rectangular.

When the filter assembly is in the second mode, as shown in fig. 1 and 2, the filter assembly is generally flat, and the left movable smoke guide plate, the plate body member 2 and the right movable smoke guide plate are sequentially connected. The edge profile of the outer surface of the filter assembly is rectangular. When filter assembly was in the second mode, two movable smoke deflector 1 all high back low slope settings before, in fact, filter assembly is whole also high back low slope settings before. When the filter assembly is in the second mode, the included angle between the filter assembly and the horizontal plane is 15 degrees, namely the included angle between the outer surface of the filter assembly and the horizontal plane is 15 degrees. When the filter component is in the second mode, the air inlet channels on the two sides are respectively sealed by the corresponding movable smoke guide plates 1. The fan may also be operated when the filter assembly is in the second mode, except that the generated airflow can only flow into the filter screen.
The oil cup 4 is located below the rear end of the filter assembly when the filter assembly is in the first mode and the second mode. The grease attached to the filter assembly is collected to the rear end of the filter assembly under the action of self gravity, and the grease drips from the rear end of the filter assembly and enters the oil cup 4.
The foregoing is merely a preferred embodiment of the present invention and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the two movable smoke guide plates may be made of stainless steel plates without holes. For another example, the size of the air intake channel formed between the movable smoke guide plate and the smoke collection cavity at an interval may be adjustable, specifically, the size may be adjusted based on a control instruction input by a user, or the size may be automatically adjusted based on a fan operation gear of the range hood or a detected smoke concentration. For another example, the filter assembly may be angled at 30 degrees or other angles less than 30 degrees from horizontal when the filter assembly is in the second mode. As another example, the angle of inclination of the smoke collection chamber may be 30 degrees or other angles less than 30 degrees. For example, the bottom opening of the truncated V shape may be directed toward the inside of the hood. For another example, a filter element may be further provided, and the two movable smoke guide plates and the filter element are spaced to form an air inlet channel, that is, "the air inlet channel" is spaced between the two movable smoke guide plates and the filter element (rather than the smoke collection cavity). For another example, the two movable smoke guide plates may be provided with air inlet holes respectively. For another example, the air inlet channel formed between the movable smoke guide plate and the smoke collection cavity may be only partially closed by the corresponding movable smoke guide plate when the filter assembly is switched to the second mode. For another example, the driving device is not limited to the solution shown in the present embodiment, and other existing driving solutions that can achieve the purpose of the present application may be used for reference.
