Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a range hood and a range hood cabinet integrated unit. Background Technology

[0002] To achieve aesthetic appeal and minimize kitchen space usage, slim range hoods typically have a body thickness (including the smoke collection hood and the fan box) of around 20cm. When installed in the kitchen, the fan box extends into the kitchen cabinets, which are usually around 50cm thick. This difference in thickness results in a significant gap between the fan box and the mounting holes at the bottom of the cabinet.

[0003] During normal operation of a range hood, if external turbulence causes fumes to escape or the range hood's airflow is insufficient to completely absorb the fumes, some fumes will enter the cabinet through the gap between the fan box and the cabinet, causing stains inside the cabinet. Simultaneously, the noise generated by the fan components inside the fan box will also be transmitted to the outside of the cabinet through the gap, increasing the overall noise level of the range hood. Utility Model Content

[0004] One of the technical problems solved by this utility model is to provide a range hood that can effectively solve the technical problem in the prior art where there is a gap between the air box of the range hood and the cabinet, which causes oil fumes to enter the cabinet and pollute the cabinet, and increases the noise of the range hood.

[0005] The second technical problem solved by this utility model is to provide an integrated range hood and cabinet unit, which can effectively solve the technical problem in the prior art where there is a gap between the range hood's fan box and the cabinet, causing oil fumes to enter the cabinet and pollute it, and increasing the noise of the range hood.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] Range hoods include:

[0008] Smoke hood;

[0009] A bellows, which is installed at the top of the smoke hood and extends into the cabinet;

[0010] A baffle is movably installed on the top of the smoke hood and has an extended position and a retracted position; when the baffle is in the extended position, the baffle extends to the outside of the smoke hood to cover the gap between the air box and the bottom mounting hole of the cabinet; when the baffle is in the retracted position, the baffle surrounds the periphery of the air box.

[0011] Compared with the prior art, the range hood described in this utility model has the following beneficial effects:

[0012] The baffle is movably installed at the top of the smoke hood and has an extended and retracted position. When the range hood is installed in a cabinet and the size of the fan box is smaller than the mounting hole size at the bottom of the cabinet, the baffle is in the extended position, extending to the outside of the smoke hood to seal the gap between the fan box and the cabinet. This ensures a proper fit between the range hood and the cabinet, improving the aesthetics of the installation and preventing grease from entering the cabinet through the gap, thus maintaining cleanliness inside the cabinet. It also blocks noise from the fan box during operation. When the fan box is fitted to the cabinet, the baffle is in the retracted position, surrounding the fan box. It still absorbs noise generated by the fan box and interrupts its transmission path, achieving good noise reduction.

[0013] In one embodiment, the baffle is pivotally connected at its bottom end along the height direction of the retracted position to the top of the smoke hood, so as to rotate between the extended position and the retracted position.

[0014] In one embodiment, the baffle includes:

[0015] The first baffle is pivotally connected to the top of the smoke collection hood at its bottom end along the height direction of the retracted position.

[0016] The second baffle is pivotally connected to at least one end of the first baffle along its length; when the baffle is flipped to the unfolded position, the first baffle and the second baffle are horizontally connected; when the baffle is flipped to the folded position, the second baffle and the first baffle are connected at an angle.

[0017] In one embodiment, a second baffle is pivotally connected to both ends of the first baffle along its length, and when the baffle is flipped to the retracted position, the second baffle is connected to the first baffle at a right angle.

[0018] In one embodiment, the baffle and / or the bellows are provided with a locking member, and when the baffle is flipped to the retracted position, the baffle is fixedly connected to the bellows through the locking member.

[0019] In one embodiment, the locking element is a magnetic element, and when the baffle is flipped to the retracted position, the baffle is attracted to the bellows.

[0020] In one embodiment, the baffle further includes an extension plate, the baffle being provided with the extension plate, and the extension plate being adjustable in height along the retracted position of the baffle.

[0021] In one embodiment, the baffle is further provided with a limiting member. One of the limiting member and the extension plate is elastically provided with a protrusion, and the other is provided with a plurality of limiting holes. The plurality of limiting holes are arranged at intervals along the height direction of the baffle, and the protrusion engages with the corresponding limiting hole.

[0022] In one embodiment, a sound-absorbing layer is provided on the side of the baffle facing the air box.

[0023] The second technical problem mentioned above is solved by the following technical solution:

[0024] The range hood cabinet unit includes a cabinet and the aforementioned range hood. The range hood's air box extends into the cabinet, and the range hood's baffle is movably installed on the top of the smoke collection hood to cover the gap between the air box and the bottom mounting hole of the cabinet or to surround the air box.

[0025] The integrated range hood and cabinet unit described in this utility model has the following advantages compared with the prior art:

[0026] The baffle is movably installed at the top of the smoke hood and has an extended and retracted position. When the range hood is installed in a cabinet and the size of the fan box is smaller than the mounting hole size at the bottom of the cabinet, the baffle is in the extended position, extending to the outside of the smoke hood to seal the gap between the fan box and the cabinet. This ensures a proper fit between the range hood and the cabinet, improving the aesthetics of the installation and preventing grease from entering the cabinet through the gap, thus maintaining cleanliness inside the cabinet. It also blocks noise from the fan box during operation. When the fan box is fitted to the cabinet, the baffle is in the retracted position, surrounding the fan box. It still absorbs noise generated by the fan box and interrupts its transmission path, achieving good noise reduction. Attached Figure Description

[0038] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1 As shown in the figure, this embodiment proposes a range hood, which includes a smoke collection hood 1 and a fan box 2. The fan box 2 is installed on the top of the smoke collection hood 1, and a fan assembly is installed inside the fan box 2. The fan assembly is used to exhaust the oil fumes in the smoke collection hood 1 to the outside through the fan box 2.

[0043] Specifically, the thickness of a slim range hood (the front-to-back dimension in the diagram) is typically around 20cm, while the thickness of cabinet 10 is typically around 50cm. When the range hood is installed in cabinet 10, this difference in thickness results in a large gap 101 between the fan box 2 and the mounting holes at the bottom of cabinet 10. When external turbulence causes fumes to escape or the range hood's airflow is insufficient to completely absorb the fumes, some fumes will enter the interior of cabinet 10 through the gap 101, causing stains inside the cabinet 10. Simultaneously, the noise generated by the fan components inside fan box 2 will also be transmitted to the outside of cabinet 10 through the gap 101, increasing the operating noise of the range hood.

[0044] To solve the above problems, such as Figures 2-4 As shown, the range hood in this embodiment also includes a baffle 3, which is movably installed on the top of the smoke collection hood 1 and has an extended position and a retracted position. When the baffle 3 is in the extended position, the baffle 3 extends to the outside of the smoke collection hood 1 to cover the gap 101 between the air box 2 and the bottom mounting hole of the cabinet 10; when the baffle 3 is in the retracted position, the baffle 3 surrounds the periphery of the air box 2.

[0045] Specifically, such as Figure 2 and Figure 3 As shown, when the range hood is installed in the cabinet 10 and the size of the fan box 2 is smaller than the size of the mounting hole at the bottom of the cabinet 10, the baffle 3 is in the unfolded position. The baffle 3 extends to the outside of the smoke collection hood 1 to seal the gap 101 between the fan box 2 and the cabinet 10, so that the range hood and the cabinet 10 are compatible, improving the aesthetics of the range hood installed in the cabinet 10. At the same time, it prevents oil fumes from entering the interior of the cabinet 10 through the gap 101, causing oil stains inside the cabinet 10, thus keeping the interior of the cabinet 10 clean. In addition, it can also block the noise inside the fan box 2 during the operation of the range hood. Figure 4As shown, when the air box 2 is fitted to the cabinet 10, the baffle 3 is in the retracted position. The baffle 3 surrounds the air box 2, still absorbing the noise generated by the air box 2 and interrupting the noise transmission path, achieving a good noise reduction effect. Furthermore, when the baffle 3 is in the extended position, it seals the gap 101 between the air box 2 and the cabinet 10, eliminating the need for users to add an additional baffle or drill holes in the cabinet 10 for a recessed fit, thus reducing the installation difficulty of the range hood. Simultaneously, when the baffle 3 is in the extended position and overlaps parallel to the top of the smoke hood, it can also serve as a storage platform for placing kitchen utensils, condiments, and other items, thus providing storage.

[0046] like Figure 3 and Figure 5 As shown, the bottom end of the baffle 3 along the height direction (up and down direction in the figure) of the retracted position is pivotally connected to the top end of the smoke hood 1, allowing it to rotate between the extended and retracted positions. In this embodiment, when the baffle 3 is flipped to the extended position, the baffle 3 is parallel to and overlaps the top end of the smoke hood 1, and the top end of the baffle 3 along the height direction of the retracted position extends to the outside of the smoke hood 1. The baffle 3 is installed on the smoke hood 1 via a pivot connection, allowing the baffle 3 to flip relative to the smoke hood 1 between the extended and retracted positions, enabling the baffle 3 to be quickly installed and improving the assembly efficiency of the range hood. Simultaneously, the baffle 3 in the extended position overlaps the top end of the smoke hood 1, limiting the flipping angle of the baffle 3 by the smoke hood 1 to prevent excessive anti-rotation angle. When the baffle 3 is flipped to the retracted position, the baffle 3 is vertically positioned at the top end of the smoke hood 1, which better reduces the noise generated by the fan box 2. In other embodiments, when the baffle 3 is flipped to the unfolded position, the baffle 3 can also be inclinedly set at the top of the smoke hood 1, as long as it can block the gap 10 between the air box 2 and the cabinet 10; when the air box 2 and the cabinet 10 are adapted and the baffle 3 is in the folded position, the baffle 3 can also be inclinedly set at the top of the smoke hood 1 in a non-vertical manner, that is, the inclination angle of the baffle 3 relative to the top of the smoke hood 1 can be an acute angle or an obtuse angle, as long as it can surround the periphery of the air box 2.

[0047] Specifically, the baffle 3 is rotatably mounted to the smoke hood 1 via a hinge 8. The hinge 8 includes a first hinge and a second hinge. One end of the first hinge is integrally provided with a pin, and one end of the second hinge is integrally provided with a sleeve. The pin passes through the sleeve, allowing the first and second hinges to be pivotally connected. One of the first and second hinges is fixedly connected to the baffle 3 by screws, and the other of the first and second hinges is fixedly connected to the smoke hood 1 by screws, so that the baffle 3 is pivotally connected to the smoke hood 1 via the hinge 8. In other embodiments, the baffle 3 can also be mounted to the smoke hood 1 via a hinge structure, a rotating shaft, or other rotating modules. The baffle 3 and the smoke hood 1 can also be connected to the hinge 8 by welding or other methods, which are not specifically limited here.

[0048] like Figure 3 and Figure 4 As shown, the baffle 3 includes a first baffle 31 and a second baffle 32. The bottom end of the first baffle 31 in the height direction of the folded position is pivotally connected to the top end of the smoke hood 1. At least one end of the first baffle 31 in the length direction (left-right direction in the figure) is pivotally connected to the second baffle 32. When the baffle 3 is flipped to the unfolded position, the first baffle 31 and the second baffle 32 are horizontally connected, forming a horizontal plate in this embodiment. When the baffle 3 is flipped to the folded position, the second baffle 32 is connected to the first baffle 31 at an angle, forming a vertical plate in this embodiment. When the baffle 3 is flipped to the unfolded position, the first baffle 31 and the second baffle 32 are laid flat to form a horizontal plate, and the gap 101 is sealed by the horizontal plate. During the process of baffle 3 flipping to the retracted position, the first baffle 31 and the second baffle 32 first flip to a vertical position. Then, the second baffle 32 flips relative to the first baffle 31 and connects to the first baffle 31 at an angle, so that the vertical plate forms a U-shape, which facilitates the vertical plate surrounding the periphery of the bellows 2. Specifically, each end of the first baffle 31 along its length is pivotally connected to a second baffle 32. When baffle 3 flips to the retracted position, the second baffle 32 is connected to the first baffle 31 at a right angle. Specifically, when baffle 3 is in the retracted position, the first baffle 31 and the two second baffles 32 form a right-angled U-shaped plate. The first baffle 31 is parallel to and directly opposite the front side of the bellows 2, and the two second baffles 32 are parallel to and directly opposite the left and right sides of the bellows 2, respectively. Both the first baffle 31 and the second baffle 32 are adapted to the size of the bellows 2 to ensure the noise reduction effect of the baffle 3 on the bellows 2.

[0049] like Figure 5 and Figure 6 As shown, the first baffle 31 and the second baffle 32 are also rotatably connected by a hinge 8. In other embodiments, the first baffle 31 and the second baffle 32 can also be rotatably connected by other rotating modules such as hinge structures and rotating shafts, which are not specifically limited here.

[0050] In one embodiment, the baffle 3 and / or the bellows 2 are provided with a locking member 4. When the baffle 3 is flipped to the retracted position, the baffle 3 is fixedly connected to the bellows 2 by the locking member 4. The locking member 4 improves the stability of the baffle 3 in the retracted position, preventing the baffle 3 from shaking or flipping in the retracted position. The locking member 4 can be installed only on the baffle 3 or the bellows 2. For example, the locking member 4 can be a magnet, adhesive, or other components to achieve a fixed connection between the baffle 3 and the bellows 2 by magnetic attraction or adhesion. Of course, the locking member 4 can also be provided on both the baffle 3 and the bellows 2, for example, a snap-fit ​​structure, screws, or other fasteners. In this case, one of the baffle 3 and the bellows 2 is provided with a snap-fit, and the other of the baffle 3 and the bellows 2 is provided with a snap-fit ​​structure; or, the baffle 3 has a through hole, and the bellows 2 has a corresponding threaded hole. After the screws or other fasteners pass through the coaxial through hole and threaded hole in sequence, the baffle 3 is locked to the bellows 2. In addition, the baffle 3 in the retracted position can also be fixedly connected to the bellows 2 by welding, which will not be listed here.

[0051] In this embodiment, the locking member 4 is a magnetic member. When the baffle 3 is flipped to the folded position, the baffle 3 and the air box 2 are attracted to each other. Since the baffle 3 and the air box 2 are connected by magnetic attraction, when the baffle 3 is flipped to the folded position, the baffle 3 approaches the air box 2 and is quickly attracted by the magnetic member. At the same time, simply moving the baffle 3 away from the air box 2 will break the magnetic connection between the baffle 3 and the air box 2, making it easy for the baffle 3 to quickly flip to the unfolded position.

[0052] Specifically, the bellows 2 is generally made of a metal material that attracts magnets. For example... Figure 5 As shown, magnetic elements (magnets) are installed on the two second baffles 32 so that the two second baffles 32 are respectively attracted to the air box 2 by the magnetic elements. In other embodiments, the locking member 4 may also include a first magnetic element and a second magnetic element that attract each other, with the first magnetic element installed on the second baffle 32 and the second magnetic element installed on the air box 2. When the baffle 3 is flipped to the folded position, the first magnetic element and the second magnetic element approach each other and attract each other.

[0053] In one embodiment, such as Figure 5 and Figure 7 As shown, a sound-absorbing layer 7 is provided on the side of the baffle 3 facing the air box 2. By providing the sound-absorbing layer 7, the noise absorption capacity of the baffle 3 for the air box 2 is improved, further enhancing the noise reduction effect of the baffle 3. Specifically, the sound-absorbing layer 7 can be sound-absorbing cotton or other absorbent materials. (When in the folded position) The sound-absorbing layer 7 is bonded to the side of the first baffle 31 and the second baffle 32 facing the air box 2.

[0054] like Figure 5 and Figure 7As shown, the baffle 3 is provided with an extension plate 5, which is adjustable in height along the retracted position of the baffle 3. By providing the extension plate 5, the length of the baffle 3 extending outward from the smoke hood 1 is increased, allowing the position of the extension plate 5 relative to the baffle 3 to be adjusted according to the size of the gap 101 between the air box 2 and the cabinet 10. This enables the baffle 3 to adapt to gaps 101 of different sizes, allowing the range hood to be installed in cabinets 10 of different sizes, thus improving the versatility of the range hood.

[0055] like Figure 7 and Figure 8 As shown, the baffle 3 is also provided with limiting members 6. One of the limiting members 6 and the extension plate 5 is elastically provided with a protrusion 51, and the other is provided with multiple limiting holes 61. The multiple limiting holes 61 are arranged at intervals along the height direction of the baffle 3, and the protrusion 51 engages with the corresponding limiting hole 61. Through the engagement of the protrusion 51 with the limiting hole 61, the extension plate 5 is securely installed on the baffle 3 by the limiting member 6. At the same time, according to the different sizes of the gap 101, the protrusion 51 of the extension plate 5 selectively engages with different limiting holes 61 to adjust the position of the extension plate 5 relative to the baffle 3. Specifically, an extension plate 5 is installed on the first baffle 31 and the two second baffles 32, and limiting members 6 are installed on both sides of the first baffle 31 in the left and right directions and both sides of the second baffle 32 in the left and right directions. The limiting members 6 are fixedly installed on the first baffle 31 and the second baffle 32 by means of adhesive or screws. Multiple protrusions 51 are provided on the left and right sides along the length of the extension plate 5, and the protrusions 51 on the same side of the extension plate 5 are spaced apart along the height direction (up and down direction in the figure). Multiple limiting holes 61 are provided at intervals along the height direction of the baffle 3, so that the left and right sides of the extension plate 5 are respectively engaged with the limiting holes 6 on the left and right sides of the first baffle 31 (or the second baffle 32), thereby improving the stability of the installation of the baffle 3 and the extension plate 5, and limiting the extension plate 5 in the left and right directions, preventing the extension plate 5 from shifting position during position adjustment, and improving the position adjustment accuracy of the extension plate 5. The aforementioned protrusions 51 can be elastic plunger structures, allowing the protrusions 51 to extend and retract relative to the extension plate 5, thereby sliding into or out of the corresponding limiting holes 61.

[0056] like Figure 7 and Figure 8As shown, the baffle 3 and the limiting member 6 form a groove 62 extending along the height direction of the baffle 3, and the extension plate 5 is slidably disposed within the groove 62. Specifically, the limiting member 6 is a U-shaped clamp, and both the baffle 3 and the extension plate 5 are located within the limiting member 6, with the sound-absorbing layer 7 sandwiched between the baffle 3 and the extension plate 5. When it is necessary to adjust the position of the extension plate 5, simply pull the extension plate 5 along the height direction of the baffle 3 and slide it within the groove 62. This allows the protrusion 51 of the extension plate 5 to slide out from the corresponding limiting hole 61 and engage with other limiting holes 61, making the position adjustment operation of the extension plate 5 simple and easy, and improving the position adjustment efficiency of the extension plate 5.

[0057] It should be noted that the baffle 3 and the extension plate 5 can be made of sheet metal, glass, wood, plastic, etc. Since the baffle 3 may be used as a storage platform when flipped to the unfolded position, the baffle 3 and the extension plate 5 are preferably made of materials with good hardness and toughness.

[0058] This embodiment also proposes an integrated range hood and cabinet unit, comprising a cabinet 10 and the aforementioned range hood. The range hood's fan box 2 extends into the cabinet 10, and the range hood's baffle 3 is movably installed on the top of the smoke collection hood 1 to cover the gap 101 between the fan box 2 and the bottom mounting hole of the cabinet 10, or to surround the fan box 2. When the baffle 3 is in the extended position, it seals the gap 101 between the fan box 2 and the cabinet 10, making the range hood compatible with the cabinet 10, improving the aesthetics of the range hood installed in the cabinet 10, and preventing fumes from entering the cabinet 10 through the gap 101, thus preventing grease buildup inside the cabinet 10 and keeping the interior of the cabinet 10 clean. It also blocks noise from the fan box 2 during range hood operation. When the baffle 3 is in the retracted position, it surrounds the fan box 2, still absorbing noise generated by the fan box 2 and interrupting the noise transmission path, achieving a good noise reduction effect.

[0059] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
