Description

Technical Field

[0001] The utility model relates to a fume purifying device, in particular to a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove waste from stove combustion and fumes generated during cooking and discharge them outdoors, reduce pollution, and purify the air. In order to better absorb fumes and prevent them from escaping, a deflectable smoke shield is usually provided at the air inlet position of the air inlet panel of an existing range hood. When the smoke shield is closed, it can completely cover the air inlet of the air inlet panel. When the smoke shield is opened at a certain angle, a triangular smoke-collecting area is formed between the bottom of the smoke shield and the air inlet panel.

[0003] For example, a range hood disclosed in Chinese utility model patent application number 202322368650.9 includes a casing and a smoke baffle, the casing is provided with a first air inlet, the smoke baffle is connected to the casing in a rotational and / or translational manner relative to the casing, and can open and close the first air inlet.

[0004] The smoke baffle of the above patent needs to be opened or closed flexibly, so a certain gap is generally left between the upper end of the smoke baffle and the smoke hood during design. Otherwise, the smoke baffle is easy to collide with the smoke hood when it is opened or closed, causing malfunctions. When food is put into the pot, especially when food with water comes into contact with high-temperature oil, a large amount of oil smoke is concentrated and rises instantly. The suction force of the range hood is not enough to instantly suck the oil smoke into the range hood. At this time, some oil smoke will overflow from the gap between the smoke baffle and the smoke hood, causing smoke leakage and affecting the user experience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a range hood for the above-mentioned deficiencies in the prior art, which can effectively block the gap between the smoke shield and the smoke collecting hood after the smoke shield is opened, thereby preventing smoke from escaping from the gap.

[0007] By setting the baffle to rotate and slide relative to the smoke hood, the gap between the smoke baffle and the smoke hood after it is opened can be effectively blocked to prevent smoke from escaping from the gap without affecting the existing movement of the smoke baffle. The movement of the smoke baffle can also be used directly to drive the baffle, without the need to set up a separate driving mechanism for the baffle, thereby simplifying the structure.

[0008] In order to achieve the connection between the baffle and the smoke hood, the range hood includes an air inlet grille arranged at the air inlet, and a flange is also formed on the smoke hood. There are two flanges, and the two flanges are arranged at intervals in the left and right directions. The flanges are located above the air inlet grille, and the left and right sides of one end of the baffle close to the smoke hood are rotatably connected to the flanges on the corresponding sides, and the rotation axis direction of the baffle is in the left and right direction.

[0009] In order to achieve a sliding connection between the baffle and the smoke shield, the range hood includes a sliding bracket arranged on the side of the smoke shield facing the inner side of the smoke hood, the sliding bracket is arranged perpendicular to the smoke shield, and a sliding groove is provided on the sliding bracket, which extends along the width direction of the smoke shield. There are two sliding grooves, and the two sliding grooves are arranged at intervals along the left and right directions of the smoke shield. The left and right sides of one end of the baffle close to the smoke shield are slidably connected to the sliding grooves on the corresponding sides.

[0010] In order to set the sliding bracket, the range hood also includes a crank for flipping and connecting the smoke baffle on the smoke hood. There are two cranks, and the two cranks are respectively arranged corresponding to the left and right sides of the smoke baffle. A smoke baffle bracket is arranged on the side of the smoke baffle facing the smoke hood. The smoke baffle bracket has two and corresponds to the two cranks respectively. One end of the crank is rotatably connected to the inner side of the smoke hood, and the other end of the crank is connected to the smoke baffle bracket on the corresponding side. The two sliding brackets are respectively arranged on the smoke baffle bracket on the corresponding sides.

[0011] In order to reduce the number of parts, the sliding bracket and the smoke baffle bracket are formed in one piece.

[0012] In order to prevent interference between the sliding bracket and the air inlet grille when the smoke baffle is closed, an avoidance hole adapted to the shape of the sliding bracket is opened on the air inlet grille.

[0013] Compared with the prior art, the advantages of the utility model are: by setting a baffle, the gap between the smoke shield and the smoke hood after it is opened can be effectively blocked to prevent smoke from escaping from the gap, and the existing movement of the smoke shield will not be affected. The movement of the smoke shield can also be directly used to drive the baffle, and there is no need to set a separate driving mechanism for the baffle, thereby simplifying the structure.

The range hood further includes a crank 6 for realizing the flip connection of the smoke baffle 2 on the smoke hood 1. The crank 6 has two cranks 6, and the two cranks 6 are respectively arranged corresponding to the left and right sides of the smoke baffle 2. A smoke baffle bracket 7 is arranged on the side of the smoke baffle 2 facing the inside of the smoke hood 1. The smoke baffle bracket 7 has two and is respectively arranged corresponding to the two cranks 6. One end of the crank 6 is rotatably connected to the inner side of the smoke hood 1, and the other end of the crank 6 is connected to the smoke baffle bracket 7 on the corresponding side.

[0025] See also Figure 7 When the smoke baffle 2 is in the open state, a gap 100 is formed between the upper end of the smoke baffle 2 and the fixed panel 14 of the smoke hood 1, and the range hood further comprises a baffle 3 capable of at least partially shielding the gap 100. One end of the baffle 3 is rotatably connected to the smoke hood 1, and the other end of the baffle 3 is slidably connected to a side of the smoke baffle 2 facing the inner side of the smoke hood 1.

[0026] See also Figures 4 to 7 , a flange 12 is also formed on the smoke hood 1, and there are two flanges 12, which are spaced apart in the left-right direction. The left and right sides of one end of the baffle 3 close to the smoke hood 1 are rotatably connected to the flange 12 on the corresponding side, and the rotation axis direction of the baffle 3 is in the left-right direction. The range hood also includes a sliding bracket 5 arranged on the side of the smoke baffle 2 facing the inner side of the smoke hood 1, and the sliding bracket 5 is arranged perpendicular to the smoke baffle 2. A slide groove 51 is provided on the sliding bracket 5, and the slide groove 51 extends along the width direction of the smoke baffle 2.
