Description

Technical Field

[0001] This utility model relates to the technical field of kitchen equipment, and in particular to a side smoke baffle structure, a range hood, and an integrated stove. Background Technology

[0002] In Chinese cooking, stir-frying is a frequent cooking method that generates a large amount of high-temperature, high-concentration oil fumes. Traditional range hoods are limited by their instantaneous suction and exhaust capabilities, making it difficult to capture all the oil fumes the moment they are generated. As a result, the oil fumes that are not sucked in in time can easily escape from the sides of the range hood, causing problems such as oil fume diffusion in the kitchen environment, oil stains adhering to the walls, and user discomfort.

[0003] The current mainstream solutions for preventing cooking fumes from escaping mostly involve adding fixed baffles to both sides of the range hood. These baffles create a smoke-gathering area during cooking, effectively preventing fumes from overflowing. However, since the baffles must always be fixed to the outside of the range hood, when the range hood is not in use, the exposed baffles increase the size of the range hood and disrupt the overall aesthetic of the cabinetry, causing space conflicts with the cooktop, cabinets, and other kitchen appliances. Although some range hoods now offer foldable baffles, structural limitations often reduce the smoke-gathering area, affecting smoke extraction efficiency. Utility Model Content

[0004] Firstly, this utility model provides a side smoke-blocking structure that can reduce space occupation and open to a larger angle.

[0005] To achieve the above objectives, this utility model discloses a side smoke-blocking structure, comprising multiple side plates, each of which is rotatably connected in sequence via transition joints. The side smoke-blocking structure is used to be disposed between the flip plate and the main body of the smoke hood. The two ends of the side smoke-blocking structure are rotatably connected to the main body of the smoke hood and the flip plate respectively via a first side connecting joint and a second side connecting joint. At least one of the transition joint, the first side connecting joint, and the second side connecting joint is a universal joint, and the rest are fixed-axis rotary joints. The universal joint allows the side plate connected to it to have the degree of freedom to rotate and slide about any axis in the three-dimensional coordinate system, and the fixed-axis rotary joint allows the side plate connected to it to have the degree of freedom to rotate about one axis in the three-dimensional coordinate system.

[0006] Optionally, the universal joint includes a ball joint.

[0021] The present application will be further described in detail below with reference to the accompanying drawings. Example

[0022] This application discloses a side smoke barrier structure, referring to... Figure 1 The system includes two side panels, one of which is a first side panel 1, and the other is a second side panel 2. A transition connection 52 is formed between the first side panel 1 and the second side panel 2. The side of the first side panel 1 facing away from the second side panel 2 has a first side connection 51, and the side of the second side panel 2 facing away from the first side panel 1 has a second side connection 53. The first side panel 1 is connected to the main body 3 of the range hood via the first side connection 51. A flap 4 on the main body 3 is connected to the second side panel 2 via the second side connection 53. Rotating the flap 4 is used to open or close the smoke inlet 8 on the main body 3 of the range hood.

[0023] In this embodiment, the second side connecting pair 53 is a universal connecting pair, and the first side connecting pair 51 and the transition connecting pair 52 are both fixed-axis rotary pairs.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The universal joint includes a ball shaft 61 and a guide groove 62, which are slidably connected.

[0025] The fixed-axis rotary joint includes a rotating shaft 71 and a rotating groove, and the rotating shaft 71 and the rotating groove are rotatably connected.

[0026] The universal joint allows the second side plate 2 to have a degree of freedom of rotation about any axis in the three-dimensional coordinate system relative to the flip plate 4. The first side plate 1 has a degree of freedom of rotation about one axis in the three-dimensional coordinate system relative to the main body 3 through a fixed-axis revolute joint. The first side plate 1 and the second side plate 2 have a degree of freedom of rotation about one axis in the three-dimensional coordinate system through a fixed-axis revolute joint. The origin of the three-dimensional coordinate system is not limited to the same point. The origin of the three-dimensional coordinate system in which the second side plate 2 rotates relative to the flip plate 4 can be the center of the ball shaft 61, and an axis passing through the center of the ball shaft 61 is parallel to the extension direction of the guide groove 62. The origin of the three-dimensional coordinate system in which the direction of relative rotation of the first side plate 1 and the second side plate 2 is referenced can be an endpoint of the rotating shaft 71 between the first side plate 1 and the second side plate 2, where one axis is parallel to the direction of the central axis of the rotating shaft 71. The origin of the coordinate system in which the direction of relative rotation of the first side plate 1 and the main body 3 is referenced can be an endpoint of the rotating shaft 71 between the first side plate 1 and the main body 3, where one axis is parallel to the direction of the central axis of the rotating shaft 71. If the above three-dimensional coordinate system is the same, then the defined axis direction is not limited to the X-axis, Y-axis and Z-axis that are perpendicular to each other in the three-dimensional coordinate system, but can be any axis in the space of the three-dimensional coordinate system.

[0027] The side smoke barrier structure provided in this embodiment is connected by at least one universal joint. In the non-working state, the side panels can be folded and hidden to reduce the space occupied. In the working state, the universal joint allows one side panel to be fully unfolded between other side panels, increasing the smoke collection area and thus improving the smoke collection effect.

[0028] Reference Figure 2 The first side plate 1 is a trapezoid with four sides, defined as the first straight side 11, the hypotenuse 12, the second straight side 13, and the third straight side 14 connected end to end. The second side plate 2 is a triangle with three sides, defined as the fourth straight side 21, the fifth straight side 22, and the sixth straight side 23 connected end to end. The hypotenuse 12 of the first side plate 1 and the fourth straight side 21 of the second side plate 2 are rotatably connected by a fixed-axis revolute joint. One of the rotating shaft 71 and the rotating groove is disposed on the first side plate 1, and the other of the rotating shaft 71 and the rotating groove is disposed on the second side plate 2.

[0029] The first straight edge 11 of the first side plate 1 and the main body 3 are rotatably connected by a fixed-axis revolute joint. One of the rotating shaft 71 and the rotating groove is provided on the first side plate 1, and the other of the rotating shaft 71 and the rotating groove is provided on the main body 3.

[0030] Reference Figure 2 and Figure 3The fifth straight edge 22 of the second side plate 2, away from the fourth straight edge 21, is connected to a ball shaft 61. The ball shaft 61 is a sphere or hemisphere. A guide groove 62 is provided on the flap 4 along the width direction of the flap 4. At least a portion of the ball shaft 61 is placed in the guide groove 62. The ball shaft 61 can slide along the guide groove 62, and at the same time, the ball shaft 61 can roll within the guide groove 62 and cannot disengage from the guide groove 62 in the depth direction. Therefore, the maximum diameter of the ball shaft 61 is greater than the top opening of the guide groove 62. In other embodiments, the ball shaft 61 is connected to the flap 4, and the guide groove 62 is provided along the fifth straight edge 22 of the second side plate 2. In other embodiments, the ball shaft 61 can be located at other positions on the fifth straight edge 22 except for the end.

[0031] To avoid interference, the corners of both the first side plate 1 and the second side plate 2 can be set as rounded chamfers or straight chamfers.

[0032] In other embodiments, the side plate is provided with multiple pieces connected in sequence, and a transition connection pair 52 is provided between adjacent side plates. A universal connection pair is provided in at least one of the transition connection pair 52, the first side connection pair 51, and the second side connection pair 53, and the rest are fixed-axis rotary pairs.

[0033] In other embodiments, the fixed-axis rotary joint can be a flexible component, for example, connected between the first side plate 1 and the second side plate 2 by a silicone plate that can be folded and unfolded.

[0034] In other embodiments, the fixed-axis revolute joint is a hinge.

[0035] In other embodiments, the shapes of the different side panels can be all the same, all different, or partially different and partially the same. In this embodiment, the shape of the third straight edge 14 can be changed according to the shape of the side wall of the main body 3, so that the third straight edge 14 can fit relatively close to the side panel of the main body 3, reducing the gaps for oil fumes to escape outward. Example

[0036] Reference Figure 1 and Figure 4 This application also discloses a range hood, including a main body 3, a flap 4, and a side smoke-blocking structure described in the above embodiments.

[0037] Combination Figure 2 The main body 3 is equipped with a smoke inlet 8 for inhaling cooking fumes.

[0038] In this embodiment, the flap 4 is a square plate. The flap 4 is connected to the main body 3 by a hinge. After the flap 4 is flipped on the main body 3, it can be used to open or close the smoking port 8.

[0039] The two ends of the flap 4 along its length are connected to the main body 3 by a set of side smoke-blocking structures. The two sets of side smoke-blocking structures, the flap 4, and the main body 3 form a smoke-collecting cavity, and the smoke-collecting port 8 is located inside the smoke-collecting cavity.

[0040] The first side connecting part 51 is used to connect the first side plate 1 and the main body 3, and the second side connecting part 53 is used to connect the second side plate 2 and the flip plate 4.

[0041] When the flap 4 rotates relative to the main body 3 and opens the smoke inlet 8, the second side plate 2 is pulled outward. At the same time, the ball shaft 61 slides in the guide groove 62. The second side plate 2 changes its relative angle with the flap 4 synchronously through the ball shaft 61. The first side plate 1 rotates relative to the main body 3 to the side away from the smoke inlet 8. The first side plate 1 and the second side plate 2 rotate relative to each other and gradually unfold into a coplanar state. When the flap 4 is fully opened, the fifth straight edge 22 of the second side plate 2 and the width edge of the flap 4 approach or fit together, and the third straight edge 14 of the first side plate 1 approaches or fits together with the side wall of the main body 3. This allows the generated fumes to be better guided to the smoke inlet 8, reducing the fumes from escaping outward along the length of the flap 4. Furthermore, the universal joint allows the flap 4 and the main body 3 to open at a greater angle, improving the smoke collection effect.

[0042] When the flap 4 rotates relative to the main body 3 and closes the smoke inlet 8, the second side plate 2 is pushed inward. At the same time, the ball shaft 61 slides in the guide groove 62. The second side plate 2 changes the relative angle with the flap 4 synchronously through the ball shaft 61. The first side plate 1 rotates relative to the main body 3 toward the side facing the smoke inlet 8. The first side plate 1 and the second side plate 2 rotate relative to each other and gradually fold into an overlapping state. When the flap 4 closes the smoke inlet 8, the first side plate 1 and the second side plate 2 are located in the space formed between the main body 3 and the flap 4, which can reduce the space occupied by the side smoke blocking structure in the non-working state and keep the appearance neat.

[0043] In order to facilitate folding, when the side panels and flip panels are unfolded, there is an angle between the two side panels that is greater than 0° and less than 180°. Example

[0044] This application also discloses an integrated stove, which includes a side smoke baffle structure described in the above technical solution, and the rest of the structure is the same as in embodiment two.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
