[0046] This embodiment discloses a range hood, such as Figures 5 to 7 As shown, the range hood comprises a smoke collecting chamber assembly 1, a panel 2, a smoke baffle 3, a smoke inlet chamber 4, a decorative strip 7 and an oil baffle assembly, wherein the smoke baffle 3 can open and close the smoke inlet chamber 4. The smoke baffle 3 is connected to the smoke collecting chamber assembly 1 or the smoke inlet chamber 4 through a swing rod (not shown), and the smoke baffle 3 is opened when the swing rod swings upward, and is closed when the swing rod swings downward.

[0047] The smoke shield 3 is tilted after opening, and a non-smoke-intake area 5 is formed between the smoke shield 3 and the panel 2. The non-smoke-intake area 5 means: part of the oil smoke (such as Figure 7 The smoke entering the non-smoke intake area 5 cannot continue to move upwards due to the obstruction of the smoke baffle 3, and can only swirl in the non-smoke intake area 5. The smoke is easy to condense and form oil stains in the area below the panel 2. When the smoke baffle 3 is closed, the non-smoke intake area 5 is exposed outside the smoke baffle 3, and the oil stains in the area below the panel 2 will affect the cleanliness of the range hood appearance.

[0048] In order to solve this problem, the range hood is provided with an oil-blocking assembly, which can at least partially block the oil smoke from entering the non-smoke intake area 5. Specifically, the oil-blocking assembly is arranged at the upper end of the smoke intake chamber 4, at least partially shielded between the panel 2 and the smoke baffle 3, and part of the oil smoke rising upward will be diverted to enter the smoke intake chamber 4 after hitting the oil-blocking assembly, greatly reducing the amount of oil smoke entering the non-smoke intake area 5, avoiding the condensation of oil stains in the area below the panel 2, solving the problem of the oil stains condensed in the area below the panel 2 of the existing range hood after the smoke baffle 3 is closed, and improving the neatness of the appearance of the range hood.

[0049] The specific structure of the oil blocking component is not limited, as long as it can at least partially block the oil smoke from entering the non-smoke inlet area 5. Figures 6 to 9As shown, the oil baffle assembly includes a movable oil baffle 61. After the smoke baffle 3 is opened, the movable oil baffle 61 extends and / or turns outward to at least partially block the area below the non-smoke inlet area 5, thereby preventing oil smoke from entering the non-smoke inlet area 5; after the smoke baffle 3 is closed, the movable oil baffle 61 is reset. The movable oil baffle 61 can change its position and spatial posture as needed, which can not only prevent oil smoke from rising too high, but also avoid interfering with the closing of the smoke baffle 3, making it more convenient to use and providing a good user experience.

[0050] On the basis of the above structure, the oil baffle assembly further includes a rotating shaft 62 and a fixing seat 63. The rotating shaft 62 is fixed to a mounting base through the fixing seat 63, and the mounting base may be, but is not limited to, the smoke collecting chamber assembly 1 or the smoke inlet chamber 4, as long as the rotating shaft 62 can be stably mounted. The movable oil baffle plate 61 is connected to the rotating shaft 62, and the movable oil baffle plate 61 can rotate around the rotating shaft 62, so that the movable oil baffle plate 61 can be extended and / or turned outward.

[0051] The specific method of driving the movable oil baffle plate 61 to rotate around the rotating shaft 62 is not limited. In this embodiment, the oil baffle assembly also includes a driving elastic member 64, which can reset the movable oil baffle plate 61 or at least partially block the oil smoke from entering the non-smoke intake area 5. Specifically, a smoke intake limiter 41 is provided on the smoke intake chamber 4, and one end of the driving elastic member 64 is fixedly connected (can be but not limited to a hook connection) to the smoke intake limiter 41; an oil baffle plate driving part 611 is formed on the movable oil baffle plate 61, and the other end of the driving elastic member 64 is fixedly connected (can be but not limited to a hook connection) to the oil baffle plate driving part 611. Among them, the driving elastic member 64 can be but not limited to a spring.

[0052] The specific formation method of the oil baffle plate driving part 611 is not limited. In this embodiment, the edge of the movable oil baffle plate 61 is bent to form the oil baffle plate driving part 611, which has high processing efficiency. The movable oil baffle plate 61 and the oil baffle plate driving part 611 are an integrated structure, and the movable oil baffle plate 61 and the oil baffle plate driving part 611 are respectively located on both sides of the rotating shaft 62. When the driving elastic member 64 pushes and pulls the oil baffle plate driving part 611, the movable oil baffle plate 61 can be driven to rotate around the rotating shaft 62.

[0053] On the basis of the above structure, the smoke inlet chamber 4 is a movable structure. Specifically, the smoke inlet chamber 4 can move in the smoke collecting chamber assembly 1, and when the smoke baffle 3 is opened, it can drive the smoke inlet chamber 4 to move outward and / or turn outward, closer to the source of oil smoke, and absorb oil smoke more thoroughly; when the smoke baffle 3 is closed, it can push the smoke inlet chamber 4 to return to its original position (backward or turn inward), avoiding obstruction of the normal closing of the smoke baffle 3, and can reduce the volume of the range hood when it is not in operation, avoiding excessive occupation of kitchen space.

[0054] The rotating shaft 62 is fixed on the smoke inlet chamber 4 through the fixing seat 63, and the movable oil baffle plate 61 is connected to the rotating shaft 62. The movable oil baffle plate 61 can move outward and reset with the smoke inlet chamber 4, which is more convenient to use. The driving elastic member 64 is connected between the movable oil baffle plate 61 and the smoke inlet chamber 4. When the smoke inlet chamber 4 is in the reset state, the driving elastic member 64 is in an elastic deformation state; when the smoke inlet chamber 4 moves outward and / or turns outward, the driving elastic member 64 can drive the movable oil baffle plate 61 to rotate around the rotating shaft 62.

[0055] like Figures 6 to 12 As shown, when the smoke baffle plate 3 is opened and the movable oil baffle plate 61 moves outward with the smoke inlet chamber 4, the driving elastic member 64 drives the movable oil baffle plate 61 to rotate upward around the rotating shaft 62 through the oil baffle plate driving part 611 until it abuts against the smoke collecting chamber assembly 1. The movable oil baffle plate 61 continues to be in this spatial posture under the action of the driving elastic member 64, and is used for at least partially blocking the oil smoke from entering the non-smoke inlet area 5, so that the oil smoke cannot enter the non-smoke inlet area 5, and avoiding the adhesion of oil stains on the panel 2 in the non-smoke inlet area 5.

[0056] like Figures 13 to 19 As shown, when the smoke baffle plate 3 is closed and the movable oil baffle plate 61 is reset along with the smoke inlet chamber 4, the frame of the smoke collecting chamber assembly 1 presses down the movable oil baffle plate 61, and the movable oil baffle plate 61 rotates downward around the rotating shaft 62, and the driving elastic member 64 is stretched by the oil plate driving part 611 to form elastic deformation. In order to save space in the smoke collecting chamber assembly 1, when the smoke inlet chamber 4 is in the reset state, the movable oil baffle plate 61 is placed flat on the top surface of the smoke inlet chamber 4, and the space in the smoke collecting chamber assembly 1 for setting the smoke inlet chamber 4 only needs to be slightly larger than the smoke inlet chamber 4, and the volume of the range hood will not be significantly increased.

[0057] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, but may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
