[0027] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0028] This utility model discloses a range hood with an adjustable air intake. Please refer to [link / reference]. Figures 1 to 4 ,include:

[0029] The range hood body 1 has a suction panel 11, and a suction port 111 is provided on the suction panel 11. The suction port 111 extends along the width direction of the suction panel 11.

[0030] The air intake baffle assembly 2 is used to block part of the air intake 111, so that the air intake 111 avoids the part of the air intake baffle assembly 2 to form an effective air intake. The air intake baffle assembly 2 is used to adjust the position of the effective air intake.

[0031] In the prior art, there are usually at least two burners on the stove, and generally two. The main body 1 of the range hood is installed directly above the two burners, and the range hood exhausts the oil fumes rising from the two burners through the air intake 111. The air intake 111 extends along the width of the air intake panel 11, that is, the air intake 111 extends along the straight line arrangement direction of each burner.

[0032] The air intake baffle assembly 2 is installed at the opening of the air intake 111. The area of ​​the baffle assembly 2 is smaller than the opening size of the air intake 111. The portion of the air intake 111 not blocked by the air intake baffle assembly 2 forms an effective air intake. During the use of the range hood, fumes are drawn into the range hood from the effective air intake, completing the exhaust process.

[0033] An air intake baffle assembly 2 is installed inside the main body 1 of the range hood. By adjusting the position of the air intake baffle assembly 2, the effective air intake position of the air intake 111 can be changed. When the user uses different burners for cooking, the effective air intake of the air intake 111 can be aligned with the burner in operation, which can improve the range hood's smoke extraction effect. This addresses the technical problem of the range hood's air intake 111 having a dispersed smoke extraction function, poor smoke extraction effect, and inability to adjust the position of the effective air intake according to the working status of the two burners of the stove.

[0034] Specifically, taking two burners as an example, when the user uses the left burner, the air intake baffle assembly 2 is moved to correspond to the right burner, so that the effective air intake of the air intake 111 corresponds to the left burner, and the oil fumes generated at the left burner during use are concentratedly drawn out.

[0035] When the user uses the right burner, the air intake baffle assembly 2 is moved to align with the left burner, so that the effective air intake of the air intake 111 aligns with the right burner, thus centrally drawing out the fumes generated at the right burner during use.

[0036] When a user uses two burners simultaneously, the air intake baffle assembly 2 is moved to align with the middle position of the two burners, so that the effective air intake of the air intake 111 simultaneously aligns with the two burners on the left and right sides, thereby simultaneously and centrally extracting and exhausting the fumes generated at the two burners on the left and right sides during use.

[0037] Simply turn off the range hood when it is not needed.

[0038] This utility model relates to a range hood with an adjustable air intake. Please refer to [link / reference needed]. Figure 1 and Figure 2 The air intake baffle assembly 2 has a first position located on the left side of the air intake 111, a second position located on the right side of the air intake 111, and a third position located in the middle of the air intake 111.

[0039] When using a range hood to extract fumes from the burners below it, when the user uses the right burner, the air intake baffle assembly 2 is moved to align with the left burner. At this time, the air intake baffle assembly 2 is in the first position, and the air intake 111 forms an effective air intake corresponding to the right burner. When the user uses the left burner, the air intake baffle assembly 2 is moved to align with the right burner. At this time, the air intake baffle assembly 2 is in the second position, and the air intake 111 forms an effective air intake corresponding to the left burner. When the user uses both burners simultaneously, the air intake baffle assembly 2 is moved to align with the middle position of the two burners. At this time, the air intake baffle assembly 2 is in the middle of the air intake 111 in the third position, and the air intake 111 forms effective air intakes corresponding to both the left and right burners.

[0040] This utility model relates to a range hood with an adjustable air intake. Please refer to [link / reference needed]. Figure 3 and Figure 4 The air intake baffle assembly 2 includes a sliding connecting plate 21 and a decorative plate 22. The sliding connecting plate 21 is slidably connected to the rear side of the air intake panel 11, and the decorative plate 22 is disposed on the sliding connecting plate 21 and located inside the air intake 111.

[0041] The decorative panel 22 is located on the front side of the sliding connecting plate 21, facing the user. This allows the user to apply force to the decorative panel 22 to cause the sliding connecting plate 21 to slide relative to the air intake panel 11, thereby adjusting the position of the effective air intake opening.

[0042] Specifically, the decorative panel 22 can be connected to the sliding connecting plate 21 by means of plugging, snapping, screwing, and riveting. The decorative panel 22 is located on the surface, and its color can be changed to adjust the overall aesthetics of the range hood. At the same time, the decorative panel 22 on the surface can be used to protect the sliding connecting plate 21 and prevent oil fumes from polluting the sliding connecting plate 21. After long-term use, the decorative panel 22 can be removed and cleaned or replaced.

[0043] This utility model relates to a range hood with an adjustable air intake. Please refer to [link / reference needed]. Figure 3 and Figure 4 The rear side of the suction panel 11 is provided with two opposing flanges 112 around the suction port 111. Both flanges 112 form sliding grooves with the rear wall of the suction panel 11. The upper and lower edges of the sliding connecting plate 21 are provided with sliding parts 211, and the two sliding parts 211 are slidably connected in the sliding grooves on the corresponding sides.

[0044] Flanges 112 are provided on both the upper and lower inner walls of the air intake 11. Each flange 112 forms a sliding groove relative to the air intake panel 11, allowing the upper and lower edges of the sliding connecting plate 21 to be slidably connected to the sliding groove via sliding parts 211, thus completing the sliding installation of the sliding connecting plate 21. When force is applied to the decorative panel 22 to cause the sliding connecting plate 21 to slide relative to the air intake panel 11, the two sliding parts 211 slide within their respective sliding grooves.

[0045] The adjustable air intake of this utility model has two flanges 112, each including a first part 1121 and a second part 1122. The first part 1121 is connected to the edge of the air intake 111, and the second part 1122 is connected to the first part 1121. Along the rearward extension direction of the first part 1121, the cross-sectional area formed by the two first parts 1121 gradually decreases, and along the rearward extension direction of the second part 1122, the cross-sectional area formed by the two second parts 1122 gradually increases.

[0046] One end of each of the two first portions 1121 is fixedly connected to the inner wall of the air intake 111 of the air intake panel 11, and the other ends face each other and are tilted backward, with the first portions 1121 forming an angle greater than 90° with the air intake panel 11; one end of each of the two second portions 1122 is fixedly connected to the other end of the two first portions 1121, and both second portions 1122 form an angle less than 90° with the air intake panel 11. The sliding part 211 slidably connects the first portions 1121 and the second portions 1122.

[0047] When the oil fume is being extracted, the opening structure formed by the two first parts 1121 is constricted, and the oil fume is accelerated when passing through the first part 1121, thus increasing the speed at which the range hood extracts the oil fume. The opening structure formed by the two second parts 1122 is flared, and the oil fume is decelerated when passing through the second part 1122, thus reducing the noise when the oil fume enters the smoke collection chamber of the main body of the range hood.

[0048] By setting the first part 1121 and the second part 1122 connected as described above, the two flanges 112 formed by them form an opening structure with openings in opposite directions, so that the sliding parts 211 formed at the upper and lower edges of the sliding connecting plate 21 are respectively slidably connected to the two opening structures. The flanges 112 and the corresponding sliding parts 211 form a hook structure, which can prevent the sliding connecting plate 21 from detaching from the suction panel 11 during the sliding process, thereby ensuring the stability of the installation structure.

[0049] The adjustable air intake of this utility model has a sliding part 211 including a first extension edge 2111, a second extension edge 2112 and a third extension edge 2113. The two first extension edges 2111 are respectively connected to the upper and lower edges of the sliding connecting plate 21. One end of the second extension edge 2112 is connected to the first extension edge 2111 and the other end is connected to the third extension edge 2113. The second extension edge 2112 and the third extension edge 2113 are slidably connected between the first part 1121 and the second part 1122.

[0050] Specifically, one end of each of the two first extension edges 2111 is fixedly connected to the corresponding upper and lower edges of the sliding connecting plate 21, and the other end extends obliquely toward the user side and in opposite directions; one end of each of the two second extension edges 2112 is fixedly connected to the other end of each of the two first extension edges 2111, and the other end extends to the opposite side of the two second parts 1122. The cooperating first extension edges 2111 and second extension edges 2112 together form an opening between themselves and the sliding connecting plate 21 for the second part 1122 to be inserted. This opening forms an acute angle structure; one end of each of the two third extension edges 2113 is fixedly connected to the other end of the corresponding second extension edge 2112, and the two third extension edges 2113 extend to the opposite side of the two first parts 1121.

[0051] During use, the second part 1122 extends into the opening structure with an acute angle formed by the first extension side 2111 and the second extension side 2112, forming a hook structure, which can prevent the sliding connecting plate 21 from detaching from the suction panel 11 during the sliding process, thereby ensuring the stability of the installation structure.

[0052] The present invention relates to an adjustable air intake range hood, wherein the second extension side 2112 is arranged parallel to the second part 1122, the third extension side 2113 is arranged parallel to the first part 1121, and the connecting part of the second extension side 2112 and the third extension side 2113 is slidably connected to the connecting part of the first part 1121 and the second part 1122.

[0053] During the sliding process of the air intake baffle assembly 2, the second extension edge 2112 slides relative to the second part 1122, the third extension edge 2113 slides relative to the first part 1121, and the connection between the second extension edge 2112 and the third extension edge 2113 slides relative to the connection between the first part 1121 and the second part 1122. During this process, the parallel second extension edge 2112 and the second part 1122, the parallel third extension edge 2113 and the first part 1121, and the connection between the parallel second extension edge 2112 and the third extension edge 2113 and the connection between the first part 1121 and the second part 1122 can form a planar contact structure, ensuring the smooth sliding of the air intake baffle assembly 2.

[0054] In this embodiment of the present invention, the inclination direction of the second extension edge 2112 is the same as the inclination direction of the second part 1122, and forms an angle of less than 90° with the suction panel 11, and the inclination direction of the third extension edge 2113 is the same as the inclination direction of the first part 1121, and forms an angle of greater than 90° with the suction panel 11.

[0055] That is, the two second extension edges 2112 form a constricted structure opening towards the user side, and the two third extension edges 2113 form a flared structure opening towards the user side. When the sliding connecting plate 21 is installed on the suction panel 11, the opposing sides of the two third extension edges 2113 abut against the ends of the corresponding second parts 1122. With continuous force, the two flanges 112 undergo adaptive deformation in opposite directions until the second extension edges 2112 and the third extension edges 2113 are simultaneously inserted into the corresponding flanges 112, and the two second parts 1122 respectively enter the acute angle opening formed by the two second extension edges 2112 and the middle of the sliding connecting plate 21.

[0056] When it is necessary to detach the sliding connecting plate 21 from the suction panel 11, a force is applied to the sliding connecting plate 21 away from the user side. The two second parts 1122 form a guiding function, and the two flanges 112 and the two sliding parts 211 undergo adaptive deformation, so that the two sliding parts 211 can smoothly detach from the two flanges 112, thus completing the disassembly of the sliding connecting plate 21.

[0057] The adjustable air intake of this utility model has an arc surface at the connection between the second extension edge 2112 and the third extension edge 2113, and an arc-shaped groove at the connection between the first part 1121 and the second part 1122, with the arc surface slidably connected to the arc-shaped groove.

[0058] The curved surface and the groove surface of the curved groove form a surface contact, which can reduce the noise generated by the sliding connecting plate 21 during the sliding process.

[0059] Please refer to Figure 1 and Figure 2 The present invention relates to an adjustable air intake range hood, wherein the air intake baffle assembly 2 is provided with a protrusion 221 facing the user side. The user applies force to the air intake baffle assembly 2 through the protrusion 221 to change the position of the effective air intake.

[0060] When using the range hood to extract fumes from the burners below it, when the user uses the right burner, the user applies force to the protrusion 221, causing the air intake baffle assembly 2 to move and align with the left burner. At this time, the air intake baffle assembly 2 is in the first position, and the air intake 111 forms an effective air intake corresponding to the right burner. When the user uses the left burner, the user applies force to the protrusion 221, moving the air intake baffle assembly 2 to align with the right burner. At this time, the air intake baffle assembly 2 is in the second position, and the air intake 111 forms an effective air intake corresponding to the left burner. When the user uses both burners simultaneously, the user applies force to the protrusion 221, moving the air intake baffle assembly 2 to align with the middle position of the two burners. At this time, the air intake baffle assembly 2 is in the middle of the air intake 111, forming an effective air intake corresponding to both the left and right burners.

[0061] The protrusion 221 is fixedly connected to the decorative plate 22 of the air intake baffle assembly 2 and is located in the middle of the decorative plate 22 to facilitate user operation and to observe the specific positions moved to by both ends of the air intake baffle assembly 2.

[0062] The present invention relates to an adjustable air intake range hood, wherein a drive assembly is provided inside the main body of the range hood, and the drive end of the drive assembly is connected to the air intake baffle assembly 2. The drive assembly drives the air intake baffle assembly 2 to move to change the position of the effective air intake.

[0063] As one of the parallel solutions, the drive assembly includes a drive motor installed on the main body of the range hood, a drive gear connected to the drive end of the drive motor, and a drive rack meshing with the drive gear. The air intake baffle assembly 2 is fixedly connected to one end of the drive rack, so that the drive motor drives the drive gear to rotate, causing the drive rack and the air intake baffle assembly 2 to move linearly.

[0064] As a second alternative, the drive assembly can also employ linear drive mechanisms such as electric cylinders and pneumatic cylinders.

[0065] Based on the above embodiments, an infrared detection device is installed on the range hood. The infrared detection device is communicatively connected to the control system of the range hood, and the control system is communicatively connected to the drive component. The infrared detection device detects the working status of the two burners of the stove when the user is cooking. According to the working status of the burners, the control system controls the drive component to start and drive the air intake baffle assembly 2 to move, so as to automatically adjust the position of the effective air intake. For example, when the left burner is working, the air intake baffle assembly (2) can be moved to the right side of the air intake (111). When the right burner is working, the air intake baffle assembly (2) can be moved to the left side of the air intake. When both burners are working at the same time, the air intake baffle assembly (2) can be moved to the middle position of the air intake (111).

[0066] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
