Description

Technical Field

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

[0002] In existing technology, the oil filter of European-style range hoods is generally installed and fixed directly to the smoke collection hood at the bottom of the hood body. It is used to intercept the rising fumes during cooking, achieving the effect of separating grease. Generally, the oil filter installation structure is as follows: one side of the smoke collection hood has a slot suitable for the oil filter pins, and the other side has screws or various quick-release mechanisms. However, this installation method only ensures a secure fit at the screw or quick-release mechanism end, but cannot guarantee a secure fit at the slot where the oil filter pins are installed. Because the manufacturing process of the pin slot requires pre-reserved punching gaps and fitting dimensions, the size of the slot at the smoke collection hood needs to be larger than the size of the oil filter pins. Therefore, generally, after the oil filter of a European-style range hood is assembled, there will be some fitting gap on the pin-fixing side, causing the oil filter to loosen and resulting in abnormal noise during operation. Additionally, as... Figure 1 and Figure 2 As shown, the plug-in connection causes a gap between the oil mesh 200 and the inner wall of the fume hood 120, which allows smoke to enter through the gap, causing abnormalities in the oil circuit of the whole machine. At the same time, it also causes the accumulation of oil stains, increasing the risk of oil leakage.

[0003] Therefore, there is an urgent need for a range hood to solve the above problems. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a range hood that effectively solves the problems of abnormal noise caused by assembly gaps and smoke intrusion caused by gaps after installation. It effectively compensates for assembly gaps, resulting in quieter operation; at the same time, it effectively reduces smoke intrusion between the oil filter and the smoke collection hood, reducing oil smoke accumulation, abnormal oil dripping, and oil leakage, thus improving the user experience.

[0005] The above-mentioned technical problems are solved by the following technical solutions:

[0006] A range hood includes a housing and an oil filter. The housing has a flue, and the lower end of the housing has a smoke collection hood communicating with the flue. The oil filter is disposed on the smoke collection hood and covers the flue. The smoke collection hood has a locking hole, and the oil filter has a locking protrusion. The locking protrusion can be placed in the locking hole to connect the oil filter and the smoke collection hood. The range hood further includes:

[0007] A sealing element is disposed on the smoke collection hood and located on the side of the card hole near the flue. The length of the sealing element is not less than the length of the opening of the flue near the sealing element. When the oil mesh is connected to the smoke collection hood, the sealing element can abut against the oil mesh.

[0008] The range hood described in this utility model has the following advantages compared with the prior art:

[0009] This invention connects the oil mesh and the fume hood via a locking mechanism and a locking hole. A sealing element is installed on the side of the fume hood near the ductwork, where the locking hole is located. When the oil mesh and fume hood are connected, the sealing element elastically deforms and abuts against the oil mesh and fume hood. The elastic restoring force of the sealing element acts on the oil mesh, reducing the shaking of the oil mesh's locking protrusion within the locking hole of the fume hood. This effectively reduces problems such as oil mesh loosening and abnormal operating noise, resulting in quieter operation of the range hood. Furthermore, by setting the length of the sealing element to be no less than the length of the ductwork near the sealing element, when negative pressure is generated by the fan assembly inside the housing, the sealing element can effectively block the negative pressure created by the fan assembly. Therefore, there is no negative pressure in the gap between the oil mesh and the inner wall of the fume hood, preventing smoke from flowing into this gap and avoiding the accumulation of oil fumes. This significantly reduces the risk of abnormal oil dripping or leakage caused by smoke intruding into the narrow channel, improving the user experience.

[0010] In one embodiment, the width of the seal on the side closer to the smoke hood is greater than the width on the side farther from the smoke hood.

[0011] In one embodiment, the seal is snapped onto, glued to, or connected to the smoke hood via a connector.

[0012] In one embodiment, the seal includes a sealing body and a snap-fit ​​protrusion. The sealing body is used to abut against the oil mesh, and the snap-fit ​​protrusion is connected to the sealing body. The smoke collection hood is provided with a mounting hole, and the snap-fit ​​protrusion can snap into the mounting hole.

[0013] In one embodiment, the sealing body is provided with a plurality of the snap-fit ​​protrusions spaced apart along its length.

[0014] In one embodiment, the snap-fit ​​protrusion is integrally formed with the sealing body.

[0015] In one embodiment, a snap-fit ​​flange is provided on the side of the snap-fit ​​protrusion that connects to the sealing body, and a sealing groove is provided between the snap-fit ​​flange and the sealing body. The smoke hood located circumferentially to the mounting hole can be placed in the sealing groove, and the snap-fit ​​flange can abut against the smoke hood.

[0016] In one embodiment, the end of the snap-fit ​​protrusion away from the sealing body is provided with a guide slope.

[0017] In one embodiment, the seal is provided as a rubber component or a sponge.

[0018] In one embodiment, the distance between the seal and the card hole is set to 5mm-50mm. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] like Figures 3-6 As shown, this embodiment provides a range hood, which includes a housing 100 and an oil filter 200. The housing 100 is provided with a flue 110, and the lower end of the housing 100 is provided with a smoke collection hood 120 communicating with the flue 110. The oil filter 200 is disposed in the smoke collection hood 120 and covers the flue 110. The smoke collection hood 120 is provided with a locking hole 130, and the oil filter 200 is provided with a locking protrusion 210. The locking protrusion 210 can be placed in the locking hole 130 to connect the oil filter 200 and the smoke collection hood 120. The range hood also includes a sealing member 300, which is disposed in the smoke collection hood 120 and located on the side of the locking hole 130 near the flue 110. The length of the sealing member 300 is not less than the length of the opening of the flue 110 near the sealing member 300. When the oil filter 200 is connected to the smoke collection hood 120, the sealing member 300 can abut against the oil filter 200.

[0035] In this invention, the oil mesh 200 and the smoke hood 120 are connected by a latching protrusion 210 and a latching hole 130. By setting a sealing element 300 on the side of the smoke hood 120 near the flue 110 at the latching hole 130, the sealing element 300 can undergo elastic deformation and abut against the oil mesh 200 and the smoke hood 120 when the oil mesh 200 is connected to the smoke hood 120. Due to the elastic restoring force of the sealing element 300 acting on the oil mesh 200, the shaking of the latching protrusion 210 of the oil mesh 200 in the latching hole 130 of the smoke hood 120 is reduced, thereby effectively reducing problems such as loosening of the oil mesh 200 and abnormal operating noise, and making the range hood quieter during operation. In addition, by setting the length of the seal 300 to be no less than the length of the flue 110 on the side near the seal 300, when the fan assembly inside the housing 100 generates negative pressure, the seal 300 can effectively block the negative pressure generated by the fan assembly. Therefore, there is no negative pressure in the gap between the oil screen 200 and the inner wall of the smoke hood 120, so the flue gas will not flow into the gap, avoiding the accumulation of oil fumes in the gap. This greatly reduces the risk of abnormal oil dripping and leakage caused by the intrusion of flue gas into the narrow channel, and improves the user experience.

[0036] It is worth noting that, while ensuring machinability, the seal 300 is positioned as close as possible to the locking hole 130, or even close to the edge of the locking hole 130. For example, the distance between the seal 300 and the locking hole 130 is set to 5mm-50mm. If this distance is too small, it will lead to machining difficulties; if it is too large, it will result in a greater distance between the oil mesh 200 and the inner wall of the fume hood 120, thus requiring a larger seal 300 and increasing costs.

[0037] Preferably, the width of the sealing element 300 on the side closer to the smoke hood 120 is greater than the width on the side farther from the smoke hood 120. This arrangement increases the contact area between the wider side and the smoke hood 120, improving the reliability of installation and reducing deformation failure. Simultaneously, the narrower side, due to its less material, is more flexible, allowing for sufficient deformation upon contact with the oil mesh 200, thus improving the sealing effect. It is worth noting that the length of the sealing element 300 is its length in the left-right direction; correspondingly, the length of the opening of the flue 110 is the distance between the left and right edges of the opening where the flue 110 connects to the smoke hood 120, and the width of the sealing element 300 is its width in the front-back direction.

[0038] Optionally, the seal 300 can be made of rubber, which is easily deformable, does not absorb oil fumes, has a longer service life, and provides a better sealing effect. When the seal 300 is made of rubber, it can be snapped onto, glued to, or connected to the fume hood 120 via a connector. In other embodiments, the seal 300 can also be made of sponge, which is less costly. When the seal 300 is made of sponge, it can be glued to the fume hood 120.

[0039] In this embodiment, the sealing element 300 is a rubber component. The sealing element 300 includes a sealing body 310 and a snap-fit ​​protrusion 320. The length of the sealing body 310 is not less than the width of the flue 110 near the sealing element 300, for contact with the oil mesh 200. The snap-fit ​​protrusion 320 connects to the sealing body 310 to connect the sealing element 300 to the smoke hood 120. Specifically, the smoke hood 120 has mounting holes, and the snap-fit ​​protrusion 320 can snap into these holes to connect the sealing element 300 to the smoke hood 120.

[0040] Furthermore, the sealing body 310 is provided with a plurality of snap-fit ​​protrusions 320 at intervals along its length to improve the reliability of the connection between the sealing element 300 and the smoke hood 120 along its length.

[0041] Optionally, the snap-fit ​​protrusion 320 and the sealing body 310 are integrally formed, which facilitates processing and makes the connection more reliable. Specifically, a snap-fit ​​flange 321 is provided on the side where the snap-fit ​​protrusion 320 connects to the sealing body 310. A sealing groove 322 is provided between the snap-fit ​​flange 321 and the sealing body 310. During snap-fit, the end of the snap-fit ​​protrusion 320 away from the sealing body 310 first passes through the mounting hole until the snap-fit ​​flange 321 passes through the mounting hole. At this time, the smoke hood 120 located around the mounting hole can be placed in the sealing groove 322. At the same time, the snap-fit ​​flange 321 and the sealing body 310 abut against the two sides of the smoke hood 120 respectively. Preferably, a guide slope 323 is provided on the end of the snap-fit ​​protrusion 320 away from the sealing body 310 to provide guidance for the installation of the sealing element 300 and the smoke hood 120, making the installation easier.

[0042] In this embodiment, the range hood is a European-style range hood, and its smoke collection hood 120 has a locking hole 130 on the front side. The rear side of the oil filter 200 is connected to the smoke collection hood 120 through a connecting assembly 140. In this case, only the front side of the smoke collection hood 120 is provided with the aforementioned sealing element 300. Further, two locking holes 130 are provided, spaced apart along the length direction (i.e., left-right direction) of the smoke collection hood 120, to improve the reliability of the connection between the oil filter 200 and the smoke collection hood 120. In other embodiments, both the front and rear sides of the smoke collection hood 120 are locked to the oil filter 200, therefore, the aforementioned sealing element 300 is provided between the front and rear sides of the smoke collection hood 120 and the oil filter 200.

[0043] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0044] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
