Technical Field
[0001] This utility model relates to the field of oil fume extraction equipment technology, specifically to an oil fume extraction hood housing assembly and an oil fume extraction hood. Background Technology
[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance that purifies the kitchen environment by exhausting cooking fumes from indoors to outdoors. It typically consists of a smoke collection chamber and a casing assembly. Range hoods are generally installed above the kitchen stove and quickly remove harmful cooking fumes or waste products from combustion, venting them outdoors. They also condense and collect the fumes, reducing pollution and purifying the air.
[0003] Range hoods typically have a housing assembly that encloses key components such as the motor, impeller, and circuit boards, protecting them from dust and oil stains and extending their lifespan. The housing assembly also provides a sturdy frame, ensuring load-bearing stability during suspended or recessed installations. It can also house the volute assembly and usually includes a back panel for installation and maintenance.
[0004] The back panel of the enclosure is usually fixed directly with screws. Due to the large area of the back panel, a large number of screws are required, leading to inconvenience in installation or removal, high production costs, and low efficiency. To avoid this problem, a vertical snap-fit structure is generally adopted, using snap-fits in the middle of the enclosure's back panel to replace some screws, thereby improving efficiency and reducing costs.
[0005] However, in the relevant box assembly installation technology, the upright snap-fit structure has the problem that the snap-fit is easy to deform, and the contact force is concentrated after the snap-fit is installed, which can easily cause the corresponding hole to deform, thus causing the installation surface to have gaps and oil leakage. Utility Model Content
[0006] In view of the above-mentioned defects in the prior art, the present invention provides a range hood housing assembly and a range hood to solve at least one of the above-mentioned technical defects in the prior art, avoid the phenomenon of concentrated contact force and easy deformation at the corresponding holes after the housing back panel is installed, and also prevent oil leakage.
[0007] A second aspect of this utility model also provides a range hood.
[0008] To achieve the purpose of this utility model, the present utility model provides a range hood housing assembly, comprising:
[0009] The enclosure panel restricts the accommodating space, and an installation groove is formed between the first and last ends of the enclosure panel;
[0010] The back panel of the enclosure is detachably mounted in the mounting slot;

[0015] The guide section is inclined to the back plate of the housing.
[0016] Preferably, the plane containing the fixing section is parallel to the back panel of the housing.
[0017] Preferably, the back panel of the enclosure has a first mounting side and a second mounting side, and the enclosure side panel has a front end side and a rear end side.
[0018] Each of the buckles is evenly distributed on the first mounting side and the second mounting side, and each of the holes is evenly distributed on the first end side and the last end side.
[0019] Preferably, it also includes a back panel oil sealing plane and a housing oil sealing plane.
[0020] The backplate sealing plane is located on the first mounting side and the second mounting side.
[0021] The sealing oil plane of the box is located on the first end side and the last end side.
[0022] Preferably, the buckle is provided with reinforcing ribs.
[0023] Preferably, the length of the boundary line connecting the fixed section and the limiting section is L1, the length of the boundary line connecting the limiting section and the back plate sealing plane is L2, and the width of the insertion hole is L, where 9mm ≤ L1 < L < L2.
[0024] Preferably, the reinforcing rib extends to the guide section, the fixing section, and the limiting section.
[0025] Preferably, the back panel of the enclosure is also provided with multiple screw holes.
[0026] The second aspect of this utility model provides a range hood, including the aforementioned range hood housing assembly and range hood body.
[0027] The range hood housing assembly is located on the range hood body.
[0028] The beneficial effects of this utility model are as follows: The range hood housing assembly provided by this utility model features a detachable back panel mounted on an installation groove formed by the housing side panel; multiple buckles are provided on both sides of the back panel, and multiple insertion holes are provided at the beginning and end of the housing side panel, with each buckle engaging with each insertion hole; the fixing section of the buckle is designed as a planar structure, so that when the back panel is installed on the installation groove, each buckle engages with each insertion hole, and the plane of the fixing section abuts against the plane near the insertion hole on the housing side panel, increasing the force-bearing area of the buckle, avoiding the phenomenon of concentrated contact force and easy deformation of the corresponding insertion hole after the back panel is installed, and preventing the installation surface between the back panel and the housing side panel from gapping and causing oil leakage.

[0043] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.
[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0045] The following is combined with Figures 1 to 6 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.
[0046] Combination Figures 1 to 6 The present invention provides a range hood housing assembly, which includes a housing enclosure 100 and a housing back panel 200.
[0047] The enclosure panel 100 defines a storage space 110, and a mounting groove 120 is formed between the first and second ends of the enclosure panel 100. The storage space 110 can accommodate and enclose key components of the range hood, such as the motor, impeller, and circuit board.
[0048] The back panel 200 is detachably mounted in the mounting groove 120. The range hood housing assembly also includes a top panel 500, which is mounted above the side panel 100. The back panel 200 can be mounted behind the side panel 100. After being mounted in the mounting groove, the back panel 200 is fixed to both the top panel 500 and the side panel 100.
[0049] Multiple buckles 300 are provided on both sides of the back panel 200 of the box, and multiple holes 400 are provided at the beginning and end of the box side panel 100. Each buckle 300 is fastened and matched with each hole 400.
[0050] The buckle 300 has a fixing section 310, which is a planar structure.
[0051] When the enclosure back panel 200 is installed on the mounting groove 120, each buckle 300 is fastened to each insertion hole 400, and the plane of the fixing section 310 abuts against the plane near the insertion hole 400 on the enclosure panel 100.
[0052] It is understood that the range hood housing assembly provided in the embodiments of this utility model detachably mounts the housing back plate 200 onto the mounting groove 120 formed by the housing enclosure 100; and multiple buckles 300 are provided on both sides of the housing back plate 200, and multiple insertion holes 400 are provided at the first and last ends of the housing enclosure 100, with each buckle 300 engaging with each insertion hole 400; the fixing section 310 of the buckle 300 is set as a planar structure, so that when the housing back plate 200 is installed on the mounting groove 120, each buckle 300 engages with each insertion hole 400, and the plane of the fixing section 310 abuts against the plane near the insertion hole 400 on the housing enclosure 100, thereby increasing the force-bearing area of the buckle 300, avoiding the phenomenon of concentrated contact force and easy deformation of the corresponding insertion hole 400 after the housing back plate 200 is installed, and preventing the installation surface between the housing back plate 200 and the housing enclosure 100 from gapping and causing oil leakage.
[0053] Specifically, in combination Figure 5 and Figure 6 In some embodiments of this utility model, the buckle 300 further includes a guide section 320 and a limiting section 330.
[0054] The first end of the limiting section 330 is set on the back plate 200 of the housing, the first end of the fixing section 310 is connected to the second end of the limiting section 330, and the second end of the fixing section 310 is connected to the guide section 320.
[0055] The guide section 320 and the back panel 200 of the box are set at an angle.
[0056] During the installation of the enclosure back panel 200 into the mounting slot 120, the guide section 320 first snaps into the insertion hole 400, abutting against the enclosure side panel 100. Then, the fixing section 310 gradually slides into the insertion hole 400, pressing the enclosure side panel 100 tightly. The limiting section 330 then positions the enclosure back panel 200 in the predetermined position, achieving a fixed connection between the enclosure back panel 200 and the enclosure side panel 100. The guide section 320 allows the snap fastener 300 to be easily and quickly inserted into the insertion hole 400.
[0057] Furthermore, to ensure that the fixing section 310 has the largest possible contact area with the housing panel 100 after sliding into the insertion hole 400, thereby guaranteeing uniform stress on the buckle 300 and the insertion hole 400 and preventing deformation; combined with Figures 4 to 6 In some embodiments of this utility model, the plane where the fixing section 310 is located is parallel to the back plate 200 of the box.
[0058] Combination Figure 3 In order to make the fixation between the back panel 200 and the enclosure panel 100 more stable and to prevent loosening, in some embodiments of this utility model, the back panel 200 has a first mounting side 210 and a second mounting side 220, and the enclosure panel 100 has a front end side 130 and a rear end side 140.
[0059] Each buckle 300 is evenly distributed on the first mounting side 210 and the second mounting side 220, and each socket 400 is evenly distributed on the first end side 130 and the last end side 140. For example, three symmetrical buckles 300 are provided on the first mounting side 210 and the second mounting side 220, and three symmetrical sockets 400 are provided on the first end side 130 and the last end side 140, respectively. Each buckle 300 corresponds to each socket 400, the first mounting side 210 corresponds to the first end side 130, and the second mounting side 220 corresponds to the last end side 140.
[0060] To further prevent oil stains inside the cabinet from leaking through the gap between the cabinet back panel 200 and the cabinet side panel 100, thereby protecting the kitchen environment and user health, combined with Figure 2 and Figure 3 In some embodiments of this utility model, the range hood housing assembly further includes a back panel oil-sealing plane 230 and a housing oil-sealing plane 150.
[0061] The back panel oil sealing surface 230 is provided on the first mounting side 210 and the second mounting side 220. The back panel oil sealing surface 230 is provided on both sides of the enclosure back panel 200 to increase the strength of the enclosure back panel 200 and prevent oil from flowing out of the enclosure. The buckle 300 can pass through the back panel oil sealing surface 230 and be fixed to the enclosure back panel 200.
[0062] The sealing oil plane 150 of the box is set on the first side 130 and the last side 140. The sealing oil plane 150 of the box is set on both sides of the box enclosure 100. The sealing oil plane 150 of the box cooperates with the sealing oil plane 230 of the back plate of the box back plate 200 to achieve the sealing of the box. The insertion hole 400 can pass through the sealing oil plane 150 of the box, and the width of the insertion hole 400 is L.
[0063] In addition, combined Figures 4 to 6 In some embodiments of this utility model, the buckle 300 is provided with reinforcing ribs 340. This makes the structure of the buckle 300 more stable and ensures that the buckle 300 will not deform during repeated disassembly and assembly.
[0064] Of course, the reinforcing rib 340 extends to the guide section 320, the fixing section 310 and the limiting section 330 to ensure the structural strength and stability of the entire buckle 300.
[0065] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the length of the boundary line connecting the fixing section 310 and the limiting section 330 is L1, the length of the boundary line connecting the limiting section 330 and the back plate sealing plane 230 is L2, and the width of the insertion hole 400 is L, where 9mm ≤ L1 < L < L2. For example, L can be 10mm, L1 can be 9mm, and L2 can be 11mm. When the buckle 300 on the back plate 200 is inserted into the insertion hole 400 of the enclosure panel 100, it can be locked at the limiting section 330, ensuring the accuracy of the installation position.
[0066] Combination Figure 2 In some embodiments of this utility model, the back panel 200 of the box is also provided with a plurality of screw holes 240. When the buckle 300 is fully engaged with the insertion hole 400, screws can be installed in the screw holes 240 to further enhance the stability between the back panel 200 of the box and the box side panel 100.
[0067] Combination Figures 1 to 6 In an embodiment of this utility model, a range hood is also provided, which includes the above-mentioned range hood housing assembly and range hood body.
[0068] The range hood housing assembly is located within the range hood body.
[0069] It is understandable that the range hood provided by this utility model, since it includes the aforementioned range hood housing assembly, inevitably possesses all the advantages of that assembly. Specifically, when the housing back panel 200 is installed on the mounting groove 120, each buckle 300 engages with each insertion hole 400, and the plane of the fixing section 310 abuts against the plane near the insertion hole 400 on the housing enclosure 100, thus increasing the force-bearing area of the buckle 300. This prevents the corresponding insertion hole 400 from experiencing concentrated contact force and deformation after the housing back panel 200 is installed, and prevents gaps between the housing back panel 200 and the housing enclosure 100 that could lead to oil leakage.
