Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to an embedded range hood. Background Technology

[0002] Built-in range hoods are typically installed inside kitchen cabinets. Specifically, the smoke inlet of a built-in range hood is located on the bottom wall of the casing, and an oil filter is installed at the smoke inlet. A glass panel is installed around the smoke inlet to improve the aesthetics of the range hood. However, in this structure, since the oil filter is always exposed, it not only easily affects the appearance of the range hood, but the oil droplets accumulated on the filter can also easily drip down onto the stovetop, affecting the stovetop environment, making it difficult to clean, and seriously impacting the user experience. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an embedded range hood that can reduce the risk of oil droplets falling from the oil filter onto the stove, while also improving the aesthetics of the range hood.

[0004] An embedded range hood according to an embodiment of the present invention includes: a housing having a smoke collection chamber, wherein a smoke inlet communicating with the smoke collection chamber is provided on the bottom wall of the housing, and an oil filter is detachably installed on the smoke inlet; a front panel installed on the bottom wall of the housing and located in front of the smoke inlet; a rear panel installed on the bottom wall of the housing and located behind the smoke inlet; and a middle panel movably installed below the oil filter and located between the front panel and the rear panel via a transmission mechanism, wherein the transmission mechanism is installed inside the smoke collection chamber. It extends downward to the inner surface connected to the middle panel. The transmission mechanism can drive the middle panel to flip backward from top to bottom to the unfolded position, or the transmission mechanism can drive the middle panel to flip forward from bottom to top to the folded position. When the middle panel is in the folded position, the transmission mechanism retracts into the smoke collection chamber. The middle panel covers the oil mesh and is arranged at intervals with the oil mesh. The front panel and the rear panel are arranged at intervals with the middle panel and form a smoke inlet channel connected to the smoke inlet.

[0005] The embedded range hood according to the embodiment of this utility model has at least the following beneficial effects:

[0006] In the embedded range hood of this utility model embodiment, a middle panel is provided below the smoke inlet. This middle panel can be flipped relative to the casing to a folded or unfolded position via a transmission mechanism. When the middle panel is in the folded position, it is positioned below the oil filter and spaced apart from it. The front and rear side panels are also spaced apart from the middle panel, forming a smoke inlet channel connected to the smoke inlet. Therefore, during use, fumes can flow through the smoke inlet channels on both sides of the middle panel to the smoke inlet, thereby drawing the fumes into the smoke collection chamber. Furthermore, when the middle panel is in the folded position, being below the oil filter, this structure not only prevents the oil filter from being exposed and affecting aesthetics, but also catches oil droplets falling from the oil filter, reducing the risk of oil droplets accumulating on the filter dripping onto the stove and affecting the stove environment, thus better maintaining the stove's working environment. When the middle panel is in the unfolded position, it is convenient to install the oil filter or remove it from the smoke inlet for cleaning. It also makes it easy to clean the surface of the middle panel near the smoke collection chamber, thus making the cleaning of the range hood more convenient.

[0007] According to some embodiments of the present invention, when the middle panel is in the folded position, the middle panel, the front panel, and the rear panel are on the same horizontal plane.

[0010] According to some embodiments of the present invention, a first rotating shaft is connected between the first connecting rod and the mounting base, and a second rotating shaft is connected between the first connecting rod and the second extension rod. The mounting base is provided with a limiting part located above the first rotating shaft. The first connecting rod can rotate upward relative to the mounting base, so that the second extension rod or the second rotating shaft abuts against the limiting part.

[0011] According to some embodiments of the present invention, the second extension rod and the third connecting rod have a first clearance groove with an opening facing the mounting base.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 9This utility model provides an embedded range hood, including a housing 100, a front panel 140, a rear panel 150, and a middle panel 160. The housing 100 has a smoke collection chamber 110, and the bottom wall 120 of the housing 100 has a smoke inlet 130 communicating with the smoke collection chamber 110. An oil filter 131 is detachably installed on the smoke inlet 130. The front panel 140 is installed on the bottom wall 120 of the housing 100 and located in front of the smoke inlet 130. The rear panel 150 is installed on the bottom wall 120 of the housing 100 and located behind the smoke inlet 130. The middle panel 160 is movably installed below the oil filter 131 and between the front panel 140 and the rear panel 150 via a transmission mechanism 200. The transmission mechanism 200 is installed in the smoke collection chamber 140. The transmission mechanism 200 extends downward to the inner surface of the middle panel 160. The transmission mechanism 200 can drive the middle panel 160 to flip backward from top to bottom to the unfolded position, or the transmission mechanism 200 can drive the middle panel 160 to flip forward from bottom to top to the folded position. When the middle panel 160 is in the folded position, the transmission mechanism 200 retracts into the smoke collection chamber 110. The middle panel 160 blocks the oil screen 131 and is arranged at intervals with the oil screen 131. The front panel 140 and the rear panel 150 are arranged at intervals with the middle panel 160 and form a smoke inlet channel 170 that is connected to the smoke inlet 130.

[0035] In the embedded range hood of this utility model embodiment, a middle panel 160 is provided on the lower side of the smoke inlet 130. The middle panel 160 can be flipped to a folded position or an unfolded position relative to the housing 100 by the transmission mechanism 200. When the middle panel 160 is in the folded position, the middle panel 160 is located below the oil filter 131 and is arranged at intervals with the oil filter 131. The front panel 140 and the rear panel 150 are arranged at intervals with the middle panel 160 and form a smoke inlet channel 170 connected to the smoke inlet 130. Therefore, during use, the oil fumes can flow to the smoke inlet 130 through the smoke inlet channels 170 on both sides of the middle panel 160, thereby being able to draw the oil fumes into the smoke collection chamber 110. Furthermore, when the middle panel 160 is in the folded position, since it is located below the oil filter 131, this structure not only prevents the oil filter 131 from being exposed and affecting its appearance, but also catches oil droplets falling from the oil filter 131, reducing the risk of oil droplets accumulating on the oil filter 131 dripping down onto the stove and affecting the stove environment, thus better maintaining the stove's operating environment. When the middle panel 160 is in the unfolded position, it is convenient to install the oil filter 131 or remove it from the smoke inlet 130 for cleaning. It also makes it easy to clean the surface of the middle panel 160 near the smoke collection chamber 110, thereby making the cleaning of the range hood more convenient.

[0036] It is understandable that in the above structure, since the middle panel 160 is movably mounted on the housing 100 through the transmission mechanism 200, and no exposed pivot structure is used at the end of the middle panel 160, and when the middle panel 160 is in the folded position, the transmission mechanism 200 is also retracted into the smoke collection chamber 110. Therefore, the transmission mechanism 200 will not be exposed on the outside of the middle panel 160 and will not affect the appearance of the range hood, thereby further improving the aesthetics of the range hood.

[0037] It is understood that in the embedded range hood of this utility model embodiment, since the rear panel 150 and the middle panel 160 are arranged at intervals, and the rear panel 150 is located below the oil filter 131 and arranged at intervals with the oil filter 131, the middle panel 160 is arranged at intervals with the bottom wall 120 of the housing 100. This can avoid collisions or interference between the middle panel 160 and the rear panel 150 or the oil filter 131 during the flipping process. In addition, it can also prevent the middle panel 160 from maintaining a certain distance from the housing 100 or the cabinet during the flipping process without collisions or interference. This makes the flipping of the middle panel 160 more stable and reliable.

[0038] It is understood that the front panel 140, the rear panel 150 and the middle panel 160 can all be made of glass, or they can be made of metal or other materials. This utility model does not make any specific limitations on this.

[0039] Reference Figures 1 to 3 In some embodiments, when the middle panel 160 is in the folded position, the middle panel 160 is on the same horizontal plane as the front panel 140 and the rear panel 150.

[0040] In the above structure, by setting the middle panel 160, the front panel 140, and the rear panel 150 on the same horizontal plane, the flatness of the bottom of the range hood can be maintained, thereby further improving the aesthetics of the range hood.

[0041] Reference Figures 1 to 3 In some embodiments, the bottom wall 120 of the housing 100 is provided with an upwardly recessed portion 121, the smoke inlet 130 is opened in the recessed portion 121, the front side panel 140 and the rear side panel 150 are respectively provided on the front side edge and the rear side edge of the recessed portion 121, when the middle panel 160 is in the folded position, the middle panel 160 is located below the smoke inlet 130, and the smoke inlet channel 170 is located below the periphery of the smoke inlet 130.

[0042] In the above structure, a recess 121 is provided in the bottom wall 120 of the housing 100, and the smoke inlet 130 is opened in the recess 121. The oil filter 131 is installed at the smoke inlet 130. When the middle panel 160 is in the folded position, the middle panel 160 is flush with the front panel 140 and the rear panel 150. This allows a sufficient gap to be formed between the middle panel 160 and the oil filter 131 so that the oil fumes can flow from the smoke inlet channel 170 to the smoke inlet 130, which facilitates the absorption of oil fumes.

[0043] Reference Figures 1 to 9 In some embodiments, a mounting base 250 is provided inside the smoke collection chamber 110, and a connecting seat 260 is provided on the inner surface of the middle panel 160; the transmission mechanism 200 includes a first connecting rod 210, a second connecting rod 220, a third connecting rod 230, and a fourth connecting rod 240. The first connecting rod 210 and the second connecting rod 220 are both rotatably mounted on the mounting base 250, with the first connecting rod 210 located above the second connecting rod 220. The third connecting rod 230 and the fourth connecting rod 240 are both rotatably mounted on the connecting seat 260, with the fourth connecting rod 240 located on the side of the third connecting rod 230 closer to the mounting base 250; the fourth connecting rod 240 is rotatably connected to the second connecting rod 220, and the second connecting rod 220 is rotatably connected to the first connecting rod 240. One end of the four-link 240 is provided with a first extension rod 221 extending away from the mounting base 250; the third link 230 is rotatably connected to the first extension rod 221, and the end of the third link 230 connected to the first extension rod 221 is provided with a second extension rod 231 extending away from the connecting base 260; the first link 210 is rotatably connected to the second extension rod 231; when the first link 210 and the second link 220 both rotate downward relative to the mounting base 250, the middle panel 160 can be flipped backward from top to bottom; when the first link 210 and the second link 220 both rotate upward relative to the mounting base 250, the middle panel 160 can be flipped forward from bottom to top.

[0044] In the above structure, the first link 210 and the second link 220 are both rotatably mounted on the mounting base 250 and arranged in the vertical direction. One end of the second extension rod 231 is rotatably connected to the first link 210, and the other end is rotatably connected to the first extension rod 221 of the second link 220. Thus, the first link 210, the second link 220, the first extension rod 221, the second extension rod 231, and the mounting base 250 can form a quadrilateral mechanism. The third link 230 and the fourth link 240 are both rotatably mounted on the connecting base 260. One end of the first extension rod 221 is rotatably connected to the third link 230, and the other end is rotatably connected to the fourth link 240. Thus, the third link 230, the fourth link 240, the first extension rod 221, and the connecting base 260 can form another quadrilateral mechanism. The transmission mechanism 200 is configured as a combination of two sets of quadrilateral mechanisms, which are interconnected. During use, when the first link 210 and the second link 220 rotate downwards, the second extension rod 231 pushes the two sets of quadrilateral mechanisms downwards to the unfolded state, thereby pushing the connecting seat 260 to flip backwards from top to bottom, thus allowing the middle panel 160 to flip backwards from top to bottom to the unfolded position. When the first link 210 and the second link 220 rotate upwards, the second extension rod 231 pulls the two sets of quadrilateral mechanisms upwards to the folded state, thereby pulling the connecting seat 260 to flip forwards from bottom to top, thus allowing the middle panel 160 to flip forwards from bottom to top to the folded position. By configuring the transmission mechanism 200 as two sets of interconnected quadrilateral mechanisms, the operation of the transmission mechanism 200 is more stable and reliable, and the flipping of the middle panel 160 is more stable and reliable.

[0045] It is understood that in the embedded range hood of this utility model embodiment, by setting the transmission mechanism 200 as two sets of interconnected quadrilateral mechanisms, the position of the connection fulcrum between the transmission mechanism 200 and the middle panel 160 will continuously change during the movement. That is, the end of the third link 230 and the fourth link 240 is rotatably connected to the connecting seat 260. In other words, the position and angle of the flipping fulcrum of the middle panel 160 are constantly changing during the up-and-down flipping process. This ensures that the middle panel 160 always maintains a certain distance from the casing 100 or the cabinet during the flipping process without collision or interference, thereby making the flipping of the middle panel 160 more stable and reliable.

[0046] Understandably, referring to Figure 6 and Figure 7In some embodiments, when the middle panel 160 is in the unfolded position, the horizontal height of the upper end of the middle panel 160 is lower than the horizontal height of the front panel 140 and the rear panel 150. This allows the middle panel 160 to maintain a certain distance from the housing 100 or the cabinet during the flipping process without collision or interference, thereby making the flipping of the middle panel 160 more stable and smooth.

[0047] It is understood that, in actual use, the middle panel 160 can be flipped manually by an operator, or a driving device can be installed in the smoke collection chamber 110. The output end of the driving device is rotatably connected to the first link 210 or the second link 220. When the driving device drives the first link 210 or the second link 220 to rotate downward, the middle panel 160 can be flipped downward to the unfolded position. When the driving device drives the first link 210 or the second link 220 to rotate upward, the middle panel 160 can be flipped upward to the folded position. The driving device can be a motor or a cylinder, etc., and this utility model does not specifically limit it.

[0048] Reference Figures 1 to 9 In some embodiments, a first rotating shaft 211 is connected between the first connecting rod 210 and the mounting base 250, and a second rotating shaft 212 is connected between the first connecting rod 210 and the second extension rod 231. The mounting base 250 is provided with a limiting part 251 located above the first rotating shaft 211. The first connecting rod 210 can rotate upward relative to the mounting base 250, so that the second extension rod 231 or the second rotating shaft 212 abuts against the limiting part 251.

[0049] In the above structure, by providing a limiting part 251 on the mounting base 250, the limiting part 251 can prevent the first connecting rod 210 from continuing to rotate upward. This can prevent the middle panel 160 from over-flipping when it is flipped upward to the folded position. This not only ensures the flatness and aesthetics of the bottom of the range hood, but also reduces the risk that the middle panel 160 over-flipping will reduce the distance between the middle panel 160 and the oil filter 131, thus affecting the absorption of oil fumes.

[0050] Reference Figures 1 to 9 In some embodiments, the limiting part 251 is a groove formed in the mounting base 250. When the first connecting rod 210 rotates upward, the second rotating shaft 212 can rotate close to the groove or be embedded in the groove, thereby limiting the first connecting rod 210 and thus limiting the middle panel 160.

[0051] Reference Figures 1 to 9In some embodiments, the second extension rod 231 and the third link 230 have a first clearance groove 232 with an opening facing the mounting base 250. When the middle panel 160 is in the unfolded position, the end of the fourth link 240 connected to the second link 220 is located in the first clearance groove 232.

[0052] By adopting the above structure, the first clearance groove 232 can make way for the rotation of the fourth link 240, thereby avoiding interference and jamming during the operation of the transmission mechanism 200, and making the middle panel 160 flip more smoothly and stably.

[0053] Reference Figures 1 to 9 In some embodiments, the cross-sections of the first link 210, the second link 220, the third link 230, and the fourth link 240 are all U-shaped; one end of the fourth link 240 connected to the second link 220 is sleeved on the outer periphery of the second link 220 and has a second clearance groove 241, the first extension rod 221 passes through the second clearance groove 241, and one end of the third link 230 connected to the first extension rod 221 is sleeved on the outer periphery of the first extension rod 221.

[0054] By adopting the above structure, the first link 210, the second link 220, the third link 230, and the fourth link 240 are all set as U-shaped rods, which can improve the structural strength of each rod and reduce the risk of deformation under pressure during use. In addition, the third link 230 is sleeved on the outer periphery of the first extension rod 221, and the second clearance groove 241 can make way for the second link 220, thereby avoiding interference and jamming during the operation of the transmission mechanism 200, and making the rotation of the middle panel 160 smoother and more stable.

[0055] Reference Figures 1 to 9 In some embodiments, the bottom wall 120 of the housing 100 is also provided with a first magnetic member 122. When the middle panel 160 is in the folded position, the inner surface of the middle panel 160 is attracted to the first magnetic member 122.

[0056] In the above structure, the first magnetic suction member 122 can position and fix the middle panel 160, fixing the middle panel 160 in the folded position, thereby facilitating the normal use of the range hood and reducing the risk of the middle panel 160 accidentally flipping downwards during the use of the range hood.

[0057] Reference Figures 1 to 9In some embodiments, a mounting bracket 161 is provided on the inner surface of the middle panel 160, and the connecting seat 260 is mounted on the mounting bracket 161; wherein, the mounting bracket 161 is a metal part, and a flexible pad 162 corresponding to the first magnetic member 122 is provided on the mounting bracket 161. When the middle panel 160 is in the folded position, the first magnetic member 122 can generate a magnetic attraction force on the mounting bracket 161 and abut against the flexible pad 162.

[0058] In the above structure, the inner surface of the middle panel 160 specifically refers to the surface of the middle panel 160 facing the smoke inlet 130. By setting a metal mounting bracket 161 on the inner surface of the middle panel 160, it is not only convenient to install and fix the connecting seat 260, but also allows the first magnetic suction member 122 to generate a magnetic attraction force to attract and fix the middle panel 160. By setting a flexible pad 162 on the mounting bracket 161, the first magnetic suction member 122 and the middle panel 160 can be protected, avoiding damage to the first magnetic suction member 122 or the middle panel 160 due to a strong rigid collision caused by excessive speed when the middle panel 160 is flipped upwards to abut against the first magnetic suction member 122. At the same time, it can also reduce the noise and vibration generated when the middle panel 160 abuts against the first magnetic suction member 122, thereby achieving the effect of vibration reduction and noise reduction. This not only protects the range hood, but also improves the user experience.

[0059] Understandably, in order to facilitate the adsorption and fixation of the first magnetic 122 to the middle panel 160, in addition to setting the mounting bracket as a metal part, a second magnetic 122 corresponding to the first magnetic 122 can also be directly set on the mounting bracket. The first magnetic 122 and the second magnetic 122 can generate a magnetic attraction force between them. In addition, a flexible pad 162 can be installed on the second magnetic 122. When the middle panel 160 is flipped upward to the folded position, the first magnetic 122 and the second magnetic 122 attract each other, and the flexible pad 162 is sandwiched between the first magnetic 122 and the second magnetic 122. This can buffer the collision between the first magnetic 122 and the second magnetic 122 and protect the first magnetic 122 and the second magnetic 122.
