Referring to fig. 1-7, a range hood includes a blower housing 10, a fume collection hood 20, and a blower system. The fume collecting hood 20 is arranged at the bottom of the fan frame 10, and a fume collecting cavity of the fume collecting hood 20 is communicated with the inner cavity of the fan frame 10. A blower system is provided in the blower housing 10 for providing a negative pressure for the extraction of cooking fumes.

The rear side wall of the fume collecting hood 20 extends substantially vertically so as to be wall mountable. The front side wall of the fume collecting hood 20 is inclined backwards from top to bottom, and specifically includes a first extension wall 231, a second extension wall 232 and a third extension wall 233 which are sequentially connected from top to bottom. The angle formed by the intersection of the first extending wall 231 and the vertical plane extending left and right is referred to as a first angle, and the angle formed by the intersection of the third extending wall 233 and the vertical plane extending left and right is referred to as a second angle, wherein the first angle is greater than the second angle. Correspondingly, the second extending wall 232 may extend horizontally or may extend backward from top to bottom. The first air inlet 211 is formed on the first extending wall 231, and the second air inlet 212 is formed on the second extending wall 232, that is, the second air inlet 212 is located at a rear position below the first air inlet 211.

The front edges of the left side wall 24 and the right side wall 25 of the fume collecting hood 20 of the present embodiment are also inclined backward from top to bottom, and the inclination angle is the same as the inclination angle of the first extending wall 231 of the front side wall, so that the second extending wall 232, the third extending wall 233 and the corresponding areas of the left side wall and the right side wall of the fume collecting hood 20 together define a concave area 22, and the second air inlet 212 is located on the top wall of the concave area 22.

The front side wall of the fume collecting hood 20 of the present embodiment is further provided with a fume baffle 31 and a fume guide 32. The smoke baffle 31 is driven by the first movement mechanism to deflect forwards or backwards relative to the smoke collecting hood 20 basically by taking the upper edge of the smoke baffle as a rotation axis (extending leftwards and rightwards). The upper portion of the smoke barrier 31 may be connected to the smoke collecting hood 20 by a hinge. The smoke guide plate 32 is driven by the first movement mechanism to deflect forward or backward relative to the smoke collecting hood 20 basically by taking the lower edge of the smoke guide plate as a rotation axis (extending leftwards and rightwards). The lower portion of the smoke guide plate 32 is pivotally connected to the front side wall of the smoke collecting hood 20, particularly by a hinge.

The smoke baffle 31 can deflect forwards and away from the front side wall of the smoke collecting cover 20, so that the first air inlet 211 can be opened, and can also deflect backwards and fold relative to the front side wall of the smoke collecting cover 20, so that the first air inlet 211 is shielded, and the first air inlet 211 is closed. The smoke guide plate 32 can deflect backward to approach the third extension wall 233, thereby exposing the second air inlet 212 on the second extension wall 232, and can also deflect forward (i.e., away from the third extension wall 233) to the same inclination angle as the first extension wall 231, in which state the smoke guide plate 32 can block the front opening of the recess 22 of the hood 20, i.e., close the second air inlet 212.

As shown in fig. 2, the smoke baffle 31 in the state of closing the first air inlet 211 extends downward by a portion with respect to the lower edge of the first extension wall 231, that is, the lower edge portion of the smoke baffle 31 in the state of closing the first air inlet 211 may cover a portion of the area of the open upper portion of the concave region 22, thereby preventing smoke from escaping forward from the top when too much smoke is accumulated in the concave region 22.

As shown in fig. 4, the lower edge of the smoke baffle 31 in the state of closing the first air inlet 211 is connected with the upper edge of the smoke guide plate 32 in the state of closing the second air inlet 212, so that the smoke baffle 31 and the smoke guide plate 32 together form a complete flat plate structure, and the flat plate structure can cover substantially all the area of the front side wall of the smoke collecting hood 20, thereby improving the overall aesthetic property of the range hood.

Referring to fig. 6, the first movement mechanism for driving the smoke barrier 31 to deflect in the present embodiment includes a first motor 41, a first rocker 42, and a first link 43. The first motor 41 is fixed on the fume collecting hood 20, and an output shaft of the first motor 41 is connected with a first end of the first rocker 42, so that the first rocker 42 can be driven to rotate around the output shaft of the first motor 41. The second end of the first rocker 42 is rotatably connected to the first end of the first link 43, and the second end of the first link 43 is rotatably connected to a bracket on the back surface of the smoke barrier 31.

Referring to fig. 7, the second movement mechanism for driving the smoke guide 32 to deflect in the present embodiment includes a second motor 51, a second rocker 52, and a second link 53. The second motor 51 is fixed on the fume collecting hood 20, and an output shaft of the second motor 51 is connected with a first end of the second rocker 52, so that the second rocker 52 can be driven to rotate around the output shaft of the second motor 51. The second end of the second rocker 52 is rotatably connected to the first end of the second link 53, and the second end of the second link 53 is rotatably connected to a bracket on the back of the smoke guide 32.

The smoke baffle 31 and the smoke guide 32 in the range hood of the embodiment are in different deflection position states, and can adapt to different cooking conditions: if the cooking fume is not much, the smoke guide plate 32 rotates towards the inside of the concave area 22 of the fume collecting hood 20 to expose the second air inlet 212, so that the second air inlet is not interfered with the cooker and the sight is not blocked. When the stir-frying cooking is performed, the smoke baffle 31 deflects forward to extend out to expose the first air inlet 211, so that a negative pressure area is increased, the escape of oil smoke is reduced, and the oil smoke absorbing effect is ensured.
