Description

Technical Field

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

[0002] The smoke collection hood of a range hood is used to guide the oil fumes into the interior of the range hood. The front area of ​​the smoke collection hood is usually designed with a sloping structure. Although this design is conducive to the accumulation of oil fumes, it also causes the oil to flow to the front of the smoke collection hood under the action of gravity and gradually accumulate into oil droplets.

[0003] To prevent oil dripping onto the stovetop, current technology that installs an oil cup on the front of the fume hood requires the side wall of the oil cup to be exposed at all times. It also requires the use of transparent materials to make the oil cup easy for users to observe the amount of oil inside. This makes the concealment of condensed oil ineffective. Utility Model Content

[0004] The purpose of this invention is to provide a range hood that does not require the oil cup to be made of transparent material, nor does it require the oil in the oil cup to be constantly exposed, thus providing a better concealment effect for condensed oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: In a first aspect, this utility model provides a range hood, including a smoke collection hood, a connecting structure, and an oil cup. The front side of the smoke collection hood is recessed with an installation cavity, and the installation cavity has a lower opening. The oil cup is installed in the installation cavity through the connecting structure. The connecting structure is movably connected to the smoke collection hood or the oil cup. The connecting structure is configured to allow the oil cup to extend out of the lower opening when the weight of the condensed oil in the oil cup increases.

[0006] In an optional embodiment, the connecting structure is slidably engaged with the smoke hood, and the sliding direction of the connecting structure is perpendicular to the plane where the lower opening is located.

[0007] In an optional embodiment, the connection structure includes a sliding component and an elastic element. The sliding component is slidably engaged with the smoke hood, the oil cup is connected to the sliding component, and the elastic element is disposed between the sliding component and the smoke hood. The elastic element is configured to apply a spring force to the sliding component to prevent the oil cup from extending out of the lower opening.

[0008] In an optional embodiment, the sliding assembly includes a sliding shaft and a guide bracket. The sliding shaft passes through the smoke hood and slides in cooperation with the smoke hood. The elastic element is provided between the sliding shaft and the smoke hood. The sliding shaft is connected to the guide bracket, and the guide bracket is connected to the oil cup.

[0009] In an optional embodiment, the sliding shaft includes an extension that slides with the smoke hood, the extension being configured to prevent the sliding shaft from rotating about its own axis relative to the smoke hood.

[0010] In an alternative embodiment, the sliding shaft is connected to a fastener configured to define the axial position of the guide bracket relative to the sliding shaft.

[0011] In an optional embodiment, the sliding shaft includes a limiting section, and the guide bracket is sleeved outside the limiting section, the limiting section being configured to prevent the guide bracket from rotating about the axis of the sliding shaft.

[0012] In an optional embodiment, the mounting cavity further has a disassembly port, which faces the smoke collection area formed by the smoke collection hood; One of the guide bracket and the oil cup is provided with a guide groove, and the other is provided with a sliding member that slides in conjunction with the guide groove. The sliding direction of the sliding member is perpendicular to the plane where the disassembly port is located.

[0013] In an optional embodiment, the guide bracket includes a support plate and a bending plate, the support plate being connected to the sliding shaft, and the bending plate being connected to the support plate and forming the guide groove between them.

[0014] In an optional embodiment, one of the guide groove and the sliding member is provided with a protrusion, and the other is provided with a groove that engages with the protrusion.

[0015] The range hood provided by this utility model can produce the following beneficial effects: In the range hood provided by this utility model, when the oil cup is in the initial use state, there is no condensed oil inside. At this time, the oil cup is installed and hidden in the installation cavity through the connecting structure. As the condensed oil in the oil cup increases, the total weight of the oil cup and the condensed oil increases accordingly. The connecting structure allows the oil cup to extend from the bottom opening, making it easy for the user to know whether the oil cup needs to be cleaned.

[0016] Compared to existing technologies, the range hood provided by this utility model prompts users to clean the oil cup by showing the bottom opening of the oil cup. This eliminates the need for the oil cup to be made of transparent material and the amount of oil inside the oil cup to be constantly exposed, resulting in better concealment of condensed oil.

Detailed Implementation

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] The first aspect of this utility model is to provide a range hood, such as... Figure 1 and Figure 2 As shown, the device includes a smoke hood 1, a connecting structure 2, and an oil cup 3. The front side of the smoke hood 1 is recessed with a mounting cavity 11, which has a lower opening 111. The oil cup 3 is installed in the mounting cavity 11 through the connecting structure 2. The connecting structure 2 is movably connected to the smoke hood 1 or the oil cup 3. The connecting structure 2 is configured to allow the oil cup 3 to extend out of the lower opening 111 when the weight of the condensed oil in the oil cup 3 increases.

[0025] like Figure 2 As shown, when the oil cup 3 is in its initial use state, there is no condensed oil inside. At this time, the connecting structure 2 only needs to bear the weight of the oil cup 3 itself. The oil cup 3 is installed and hidden in the mounting cavity 11 through the connecting structure 2. As the amount of condensed oil in the oil cup 3 increases, the weight of the oil cup 3 also increases. Since the connecting structure 2 is movably connected to the smoke hood 1 or the oil cup 3, under the gravity of the condensed oil, the oil cup 3 extends out from the bottom opening, making it easy for the user to know whether the oil cup 3 needs to be cleaned.

[0026] The range hood provided in the above embodiment prompts the user to clean the oil cup 3 by showing the lower opening of the oil cup 3. This eliminates the need for the oil cup 3 to be made of transparent material and for the amount of oil inside the oil cup 3 to be constantly exposed, resulting in better concealment of condensed oil.

[0027] The connecting structure 2 can employ various movable connection methods. For example, the connecting structure 2 can slide with the smoke hood 1 or the oil cup 3, causing the oil cup 3 to extend out of the lower opening 111 along the sliding direction; or the connecting structure 2 can rotate with the smoke hood 1 or the oil cup 3, causing the oil cup 3 to rotate out from the lower opening 111. Of course, it can also be a combination of the above two movable connection methods, or other movable connection methods can be used.

[0028] The connecting structure 2 can be movably matched with the smoke hood 1 or with the oil cup 3, so that when the weight of the condensed oil in the oil cup 3 increases, the oil cup 3 can extend out of the lower opening 111.

[0029] In an optional embodiment, the connecting structure 2 is slidably engaged with the smoke hood 1, and the sliding direction of the connecting structure 2 is perpendicular to the plane where the lower opening 111 is located, that is, the sliding direction is vertical.

[0030] The aforementioned sliding fit ensures that the movement path of the oil cup 3 under the gravity of the condensed oil extends vertically. That is, as condensed oil gradually accumulates inside the oil cup 3, its total weight increases accordingly, and the resulting gravitational force is precisely aligned with the allowable sliding direction of the connecting structure 2. This improves the reliability and sensitivity of the oil cup 3's response.

[0031] In alternative implementations, such as Figure 2 As shown, the connecting structure 2 includes a sliding component 21 and an elastic element 22. The sliding component 21 is slidably engaged with the smoke hood 1, the oil cup 3 is connected to the sliding component 21, and the elastic element 22 is disposed between the sliding component 21 and the smoke hood 1. The elastic element 22 is configured to apply a spring force to the sliding component 21 to prevent the oil cup 3 from extending out of the lower opening 111.

[0032] During the operation of the range hood, some of the fumes condense on the front side of the fume collection hood 1 and drip into the oil cup 3. As the condensed oil gradually accumulates, the total weight of the oil cup 3 and the oil inside it continuously increases, causing the oil cup 3 to drive the sliding component 21 to move downwards along the sliding direction. Figure 3 and Figure 4 As shown, the bottom of the oil cup 3 extends out from the lower opening 111, forming a visible exposed state.

[0033] like Figure 4 As shown, the extension amount X can be designed and adjusted according to actual needs. For example, by adjusting the stiffness coefficient of the elastic element 22, the initial preload, etc., the critical weight for triggering displacement can be set.

[0034] For example, when the oil in the oil cup 3 reaches about 50g to 100g, the oil cup 3 will slowly move down and expose the lower opening 111, prompting the user to clean the oil cup in time.

[0035] Alternatively, as long as there is condensed oil dripping into the oil cup 3, the oil cup 3 will extend its lower opening 111. As the amount of condensed oil increases, the extension amount X will be larger. The user can judge when to clean the oil cup 3 based on the size of the extension amount X.

[0036] The above-described embodiment achieves a mechanical indication function by automatically exposing the oil cup 3 when oil accumulation increases through the synergistic action of the sliding component 21 and the elastic element 22. It can complete the status indication without the need for electronic sensors or transparent materials, and has a simple, reliable, and low-cost structure, which improves the practicality and human-computer interaction of the range hood.

[0037] Specifically, the elastic element 22 can be selected as a compression spring, torsion spring, or rubber elastomer, etc., which have the ability to store energy and rebound.

[0038] In a preferred embodiment, the elastic element 22 is a compression spring, such as... Figure 2 As shown, one end of the oil cup 22 abuts against the top of the sliding assembly 21, and the other end abuts against the inner wall of the smoke collection hood 1. When the oil cup 3 is in its initial use state, the elastic element 22 is in a pre-compressed state, continuously providing an upward elastic force to the sliding assembly 21, so that the oil cup 3 is fully contained in the mounting cavity 11 and does not protrude from the lower opening 111, maintaining a neat and beautiful appearance.

[0039] In alternative implementations, such as Figure 2 As shown, the sliding assembly 21 includes a sliding shaft 211 and a guide bracket 212. The sliding shaft 211 passes through the bottom wall of the smoke hood 1 in a vertical direction and slides with the smoke hood 1, so that the sliding shaft 211 can slide on the smoke hood 1 along its own axis.

[0040] The top end of the sliding shaft 211 is located inside the smoke collection hood 1, as shown below. Figure 2 As shown, the top end of the sliding shaft 211 is provided with an extension protrusion 2113, and an elastic element 22 is provided between the extension protrusion 2113 and the inner wall of the smoke hood 1.

[0041] The bottom end of the sliding shaft 211 extends into the mounting cavity 11 and is connected to the guide bracket 212. The guide bracket 212 serves as an intermediate connecting component, and its function is to transmit the linear motion of the sliding shaft 211 to the oil cup 3, and to achieve stable suspension and synchronous movement of the oil cup 3.

[0042] When the oil cup 3 begins to collect the condensed oil flowing down from the smoke hood 1, the weight applied to the elastic element 22 by the oil cup 3 through the guide bracket 212 and the sliding shaft 211 gradually increases, causing the elastic element 22 to be gradually compressed. The sliding shaft 211 drives the guide bracket 212 and the oil cup 3 to move downward as a whole, so that the oil cup 3 gradually extends out from the lower opening 111 of the mounting cavity 11.

[0043] The above-described embodiment achieves an automatic expansion and contraction response mechanism for the oil cup 3 under weight changes through the sliding engagement of the sliding shaft 211 and the smoke hood 1, the elastic reset function of the elastic element 22, and the supporting role of the guide bracket 212. This structure is simple and reliable, requiring no electric drive or complex sensors; status indications are achieved using gravity sensing, improving the user experience while ensuring the overall neatness of the range hood's appearance and the concealment of condensed oil storage.

[0044] In alternative implementations, such as Figure 5 As shown, the sliding shaft 211 includes an extension 2111 that slides with the smoke hood 1. The extension 2111 extends axially along the sliding shaft 211, and its cross-sectional shape is non-circular, such as, but not limited to, polygons (e.g., squares, rectangles, or hexagons), ellipses, waist-shaped structures, or near-circular structures with planar surfaces. The smoke hood 1 is provided with a guide hole that matches the extension 2111. The inner wall contour of the guide hole is complementary to the outer contour of the extension 2111, thereby allowing the sliding shaft 211 to reciprocate linearly relative to the smoke hood 1 while restricting its circumferential rotation around its own axis when the sliding shaft 211 slides axially.

[0045] The above-described embodiment achieves an integrated design of sliding guidance and anti-rotation function by setting an extension section 2111 of a specific shape on the sliding shaft 211 and cooperating with the guide hole structure on the smoke hood 1. This improves the reliability and practicality of the connection structure 2 without adding extra parts.

[0046] Specifically, the extension section 2111 can be integrally formed on the sliding shaft 211, and the material can be metal or high-strength engineering plastic to ensure structural strength and wear resistance.

[0047] In addition, there are various ways to connect the sliding shaft 211 and the guide bracket 212, such as welding, snap-fitting, screw connection, etc.

[0048] In alternative implementations, such as Figure 2 As shown, the sliding shaft 211 is connected to a fastener 213, which is configured to limit the axial position of the guide bracket 212 relative to the sliding shaft 211.

[0049] Specifically, such as Figure 5 As shown, the lower end of the sliding shaft 211 is provided with an external thread section 2114, and the guide bracket 212 has a through hole for the sliding shaft 211 to pass through. The fastener 213 is in the form of a nut, which is screwed onto the external thread section 2114 and is located below the guide bracket 212. When the fastener 213 is tightened, its top surface abuts against the bottom surface of the guide bracket 212, thereby pressing the guide bracket 212 against the end face of the extension section 2111 and preventing it from moving up and down along the axis of the sliding shaft 211.

[0050] The above connection method not only ensures the stability of the axial position of the guide bracket 212, but also facilitates the assembly and disassembly of the connection structure 2 compared to the guide bracket 212 being directly welded to the sliding shaft 211.

[0051] In alternative implementations, such as Figure 5 As shown, the sliding shaft 211 includes a limiting section 2112, which is connected between the extension section 2111 and the external thread section 2114. The guide bracket 212 is sleeved on the outside of the limiting section 2112, and the limiting section 2112 is configured to prevent the guide bracket 212 from rotating around the axis of the sliding shaft 211.

[0052] By setting the aforementioned limiting section 2112, the circumferential fixation between the guide bracket 212 and the sliding shaft 211 is achieved, thereby effectively preventing the guide bracket 212 from rotating due to external disturbances or uneven force during the sliding process of the oil cup 3 under the action of gravity. This avoids causing the oil cup 3 to tilt or jam, ensuring the overall stability and reliability of the sliding assembly 21.

[0053] The cross-sectional shape of the aforementioned limiting segment 2112 is a non-circular structure, such as, but not limited to, polygons (e.g., squares, rectangles, or hexagons), ellipses, waist-shaped shapes, or near-circular shapes with planes.

[0054] like Figure 6 As shown, the guide bracket 212 is provided with a corresponding limiting hole 2125 that matches the limiting section 2112. The inner wall contour of the limiting hole 2125 is complementary to the outer contour of the limiting section 2112, thereby restricting the guide bracket 212 from rotating circumferentially around the axis of the sliding shaft 211.

[0055] In an optional implementation, to facilitate the disassembly and assembly of the oil cup 3, such as Figure 7 As shown, the mounting cavity 11 also has a disassembly port 112, which is located on the side of the mounting cavity 11 and is opened towards the smoke collection area 4 formed by the smoke collection hood 1. The disassembly port 112 allows users to remove or install the oil cup 3 by pulling it out horizontally from one side of the smoke collection area 4, improving the ease of operation, especially when the range hood is installed close to the wall for maintenance.

[0056] There are several ways to connect the oil cup 3 to the guide bracket 212, such as snap-fit, screw connection, hanging connection, etc.

[0057] To ensure stable sliding guidance of the oil cup 3 along the disassembly port 112, a cooperating guide structure is provided between the guide bracket 212 and the oil cup 3. Specifically, one of the guide bracket 212 and the oil cup 3 is provided with a guide groove 2121, and the other is provided with a sliding member 31 that slides in cooperation with the guide groove 2121. The sliding direction of the sliding member 31 is perpendicular to the plane where the disassembly port 112 is located.

[0058] by Figure 6 and Figure 8 For example, the guide bracket 212 is provided with a guide groove 2121, and the top of the oil cup 3 is connected to a sliding member 31. When it is necessary to clean the oil cup 3, the user can apply a lateral force to the oil cup 3, so that the sliding member 31 slides along the guide groove 2121, thereby pulling the oil cup 3 out laterally from the mounting cavity 11 through the disassembly port 112; conversely, during installation, it can also be pushed in the opposite direction along the same path and reset.

[0059] The guide bracket 212 can be made of metal or high-strength plastic, and has a certain rigidity and load-bearing capacity. Its shape can be designed as a U-shaped, L-shaped or multi-arm bracket structure according to the spatial layout to adapt to the installation requirements of oil cups 3 of different shapes.

[0060] Specifically, such as Figure 6 As shown, the guide bracket 212 includes a support plate 2122 and a bending plate 2123. The support plate 2122 is connected to the sliding shaft 211 and is provided with a limiting hole 2125 for the limiting section 2112 to pass through. The bending plate 2123 is connected to the support plate 2122 and forms a guide groove 2121 between the support plate 2122 and the support plate 2122.

[0061] Specifically, the guide groove 2121 is formed by the top surface of the support plate 2122 and the bottom surface of the bent plate 2123 being arranged opposite to each other. Its cross-sectional shape can be rectangular, dovetail-shaped or T-shaped, and it is used to accommodate and slide in cooperation with the sliding member 31 provided on the oil cup 3.

[0062] Through the above structural design, the guide bracket 212 not only acts as a force transmission medium to transmit the gravity of the oil cup 3 to the sliding shaft 211, but also realizes the guiding positioning and quick disassembly and assembly functions of the oil cup 3 through the cooperation of the guide groove 2121 and the sliding part 31, which improves the user's maintenance convenience while ensuring structural stability.

[0063] To ensure the stability of the connection between the oil cup 3 and the guide bracket 212, and to ensure that the oil cup 3 will not loosen or accidentally detach due to vibration or slight external force during installation, in an optional embodiment, one of the guide groove 2121 and the sliding member 31 is provided with a protrusion 2124, and the other is provided with a slot 32 that engages with the protrusion 2124.

[0064] by Figure 6 and Figure 8For example, the protrusion 2124 is provided on the inner wall of the guide groove 2121, and can be formed on the top surface of the support plate 2122; correspondingly, the slot 32 is provided on the sliding member 31.

[0065] When the sliding member 31 slides into the guide groove 2121, the protrusion 2124 can gradually align with the slot 32 and achieve elastic engagement or interference fit after entering the position, thereby forming a reliable positioning connection. The above-mentioned engagement structure can effectively prevent the oil cup 3 from axial movement or falling off during normal use without additional locking parts.

[0066] Specifically, the protrusion 2124 can adopt a barbed or hemispherical structure, and the shape of the slot 32 matches it, so that the sliding member 31 can squeeze the protrusion 2124 during the sliding process and eventually pass over its highest point to complete the locking action, realizing the "self-locking" function. During disassembly, the user only needs to apply a certain external force to make the sliding member 31 slide in the opposite direction, forcing the protrusion 2124 to disengage from the slot 32, and the oil cup 3 can be removed. The operation is simple and does not require the assistance of tools.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
