Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically relating to a range hood adapter structure and a split-type range hood. Background Technology

[0002] With the improvement of modern living standards, the large amount of oil fumes produced during cooking has impacted human health. Range hoods have become a key kitchen appliance, used to purify the kitchen environment and improve the user experience. As the core component of a range hood, the ductwork inevitably generates noise from the motor. Currently, the ductwork of most range hoods is installed inside the main housing, close to the stovetop, resulting in good smoke extraction. However, its proximity to the user's viewing area makes the motor noise significantly impactful, leading to numerous user complaints. One method to reduce noise is to design a split-type range hood.

[0003] However, the following defects are common in existing technologies:

[0004] The traditional air inlet adapter structure allows it to be used in a user's home with a right-side exhaust duct, but it is difficult to use in a user's home with a left-side exhaust duct.

[0005] The traditional way to connect the air inlet and the flexible connecting pipe is to use tin foil to connect the air inlet and the flexible connecting pipe together. This is not only time-consuming but also prone to falling off, which requires repeated installation. During the installation process, the air inlet and the flexible connecting pipe are prone to wear, thus affecting the service life. In addition, the traditional connection method is inconvenient to disassemble, which makes it difficult to inspect and replace the fan.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a range hood that solves the problem that users cannot use the range hood when the public flue is on the left.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] A range hood adapter structure includes a first opening connection part and a second opening connection part, wherein the central axes of the first opening connection part and the second opening connection part are offset, and the first opening connection part and the second opening connection part are connected by a curved surface transition.

[0010] Furthermore, the first opening connection part and the second opening connection part are partially misaligned and partially overlapped.

[0011] Furthermore, the peripheral wall of the first opening connection portion is a non-circular annular structure; the peripheral wall of the second opening connection portion is an annular structure.

[0012] Preferably, the first opening connection portion includes a straight wall and an arc-shaped wall, and the straight wall and the arc-shaped wall are connected to form a non-circular ring structure; the peripheral wall of the second opening connection portion is a circular ring or an elliptical structure.

[0013] More preferably, the first opening connection portion and the second opening connection portion are offset from one side of the straight wall of the first opening connection portion.

[0014] Furthermore, the first opening connecting part and the second opening connecting part are staggered on both sides of the overlapping area, and the first opening connecting part protrudes and extends to one side of the overlapping area, while the second opening connecting part protrudes and extends to the other side of the overlapping area.

[0015] The present invention also introduces a split-type range hood, including a flue set on a smoke collection hood and a split body equipped with a fan. The split body is provided with an interconnected air inlet and an air outlet. The flue and the split body are connected by the range hood adapter structure described above. One of the first opening connection part and the second opening connection part can be selectively and detachably connected to the air inlet or the smoke outlet, respectively.

[0016] Furthermore, an adapter is provided on the air inlet, and a flexible connecting pipe is provided on the smoke outlet. The first opening connection part of the adapter structure is connected to the adapter, and the second opening connection part is connected to the flexible connecting pipe.

[0017] Furthermore, an adapter is provided on the air inlet of the sub-unit, and a flexible connecting pipe is provided on the smoke outlet. The first opening connection part of the adapter structure is inserted into the flexible connecting pipe, and the second opening connection part is connected to the adapter.

[0018] Furthermore, the peripheral wall of the first opening connection portion is provided with multiple grooves, which are engaged with the adapter.

[0019] Furthermore, the unit body has an air inlet at the bottom and an air outlet on the side. The first opening connection part extends in the same direction as the air outlet, and the second opening connection part extends in the direction of the air outlet.

[0020] Furthermore, an adapter is provided on the air inlet, and a flexible connecting pipe is installed on the smoke outlet. The first opening connection part is inserted into the adapter, and the second opening connection part is connected to the flexible connecting pipe.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0022] 1. When a user's household uses a split-type range hood, installing the above-mentioned adapter structure can adapt to public flues in different locations, solving the problem that the adapter structure can only connect to the split unit facing a single direction.

[0023] 2. The transition structure is equipped with a transition surface, which acts as a guide to avoid the problem of increased airflow viscosity caused by the accumulation of a large amount of oil at the transition structure, thus improving the smoothness of smoke exhaust.

[0024] 3. The present invention has a simple structure and is easy to use. By providing a first opening connection part and a second opening connection part, the connection between the main body of the adapter structure and the air inlet and the flexible connecting pipe can be quickly realized, so as to realize the function of easy disassembly and assembly of the air inlet and the flexible connecting pipe and facilitate the replacement of the flexible connecting pipe. By setting the two ends of the adapter structure into a cylindrical structure, it is conducive to the standardization of the product, shortens the product development cycle, reduces costs, and makes the main body of the adapter structure suitable for mass production.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, 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 limiting this invention.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly 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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] like Figures 1 to 4 In this embodiment of the invention, the split-type range hood mainly includes a smoke collection hood 2 close to the user and a separate unit 24 located away from the user. A fan is installed inside the separate unit 24. Under the action of the fan, the smoke collection hood 2 collects the oil fumes generated during cooking and directs them into the flue 12, then through the transfer structure 1 into the separate unit 24 before being discharged. Each of these components, with its design and improvements, contributes to a better performance of the range hood. For example, by installing sound-absorbing cotton inside the flue 12, noise transmission can be significantly reduced; the transfer structure 1 allows the range hood to adapt to more complex operating conditions, improving its adaptability; and improvements to the separate unit 24 further distance the noise source from the user.

[0038] like Figure 3 and Figure 4As shown, a split-type range hood is installed in the kitchen, including a smoke collection hood 2 and a separate unit 24, with a fan installed inside the separate unit 24. Conventional range hoods generally integrate the smoke collection hood 2 and the separate unit 24 into one unit, resulting in a large smoke collection hood 2 that is both space-consuming and unsightly. In this embodiment of the invention, the smoke collection hood 2 is installed on the side wall of the kitchen, while the separate unit 24 is installed inside the ceiling wall of the kitchen. Only the switch and air intake opening need to be installed on the smoke collection hood 2, which significantly reduces the size of the hood and hides the separate unit 24 inside the ceiling. This not only reduces the noise of the range hood during cooking but also makes the entire kitchen wall look simple and beautiful. A flue 12 is provided between the smoke collection hood 2 and the separate unit 24. One end of the flue 12 is connected to the smoke outlet 22 of the smoke collection hood 2, and the other end is connected to the transition structure 1 through a flexible connecting pipe 23.

[0039] In this embodiment of the invention, the shape of the flue 12 is not limited. The flue 12 is a box-shaped structure with openings at the top and bottom. Most of the oil fumes will condense into liquid and flow down the channel wall into the oil collection device such as the oil cup set below the flue 12. Only a small portion of the oil fumes will continue to flow up the flue 12 through the transfer structure 1 and be discharged outside the building through the sub-unit 24. This reduces the probability of oil fumes adhering to and polluting the sub-unit 24, extends the service life of the main unit, and ensures that the main unit can perform high-efficiency fume extraction. In addition, the flue 12 can be set on the outer wall of the wall or embedded in the wall. When set on the outer wall of the wall, its thickness is also very thin, which does not affect the use and aesthetics of the kitchen space. In this embodiment, the flue 12 is set on the outer wall of the wall above the fume collection hood 2.

[0040] The air inlet 25 is located at the bottom of the unit 24, and the air outlet 17 can be located on the side wall or the top; taking the side wall location as an example, an exhaust pipe is connected to the air outlet 17. The exhaust pipe is horizontally arranged, and its other end connects to an exhaust vent on the wall to expel cooking fumes outdoors. A fan is installed inside the unit 24. The fan's rotation accelerates the circulation of cooking fumes, promptly drawing indoor fumes outdoors. The fan can be any type, such as a centrifugal fan, a mixed-flow fan, or an axial fan.

[0041] In this embodiment of the invention, the smoke inlet 21 of the fume hood 2 faces the stove and is used to collect the fumes generated during cooking. The smoke outlet 22 is located on the side opposite to the smoke inlet 21 and faces upward. The fumes enter the fume hood 2 through the smoke inlet 21 and flow into the flexible connecting pipe 23 through the smoke outlet 22. After passing through the transition structure 1, i.e., through the flow channel 18, the oil enters the sub-unit 24 from the air inlet 25 of the flow channel 18. Under the action of the fan, it is sprayed from the air outlet 17 towards the check valve horizontally connected to the air outlet 17 and discharged through the kitchen exhaust vent.

[0042] In this embodiment of the invention, one end of the flexible connecting pipe 23 is connected to the adapter structure 1, and the other end is connected to the smoke outlet 22. The flexible connecting pipe 23 can take many forms, such as a rigid plastic pipe, a metal pipe, or a soft plastic pipe and rubber pipe, etc., as long as it can connect the sub-body 24 and the air outlet. For example, the flexible connecting pipe 23 may be a pleated plastic pipe or a pleated rubber pipe. In this embodiment of the invention, the adapter structure 1 is located at the air inlet 25, the flexible connecting pipe 23 has a base that is fixedly connected to the smoke outlet 22, and the flexible connecting pipe 23 is fixedly installed with the second opening connection part 16 of the adapter structure 1.

[0043] The adapter structure 1 includes a first opening connection part 13 and a second opening connection part 16. The first opening connection part 13 and the second opening connection part 16 are staggered, which enables the split-type range hood to be widely used in users' homes. It can be installed and used normally whether the public flue is on the left or right side, improving the user experience.

[0044] Example 1

[0045] This invention provides a connecting structure 1 for a range hood. The connecting structure 1 includes a first opening connecting part 13 and a second opening connecting part 16. The central axes of the first opening connecting part 13 and the second opening connecting part 16 are offset, allowing for easy installation even when encountering an inclined air inlet 25 or an inclined flexible connecting pipe 23. It is also applicable to common flues in different locations. In this embodiment, the connecting structure 1 has its two vertically aligned openings with parallel axes. The first opening connecting part 13 faces upwards and has a non-circular, closed structure formed by straight and curved walls. The first opening connecting part 13 can be easily inserted into the air inlet 25, and its irregular shape makes it easy for installers to find the correct position and insert it smoothly. The first opening connecting part 13 also acts as a limit, effectively preventing the connecting structure 1 from rotating with other parts during installation. Furthermore, it is easy to mold, allowing for mass production and is suitable for various range hoods.

[0046] The adapter structure 1 can be selectively connected to either the sub-body 24 or the flue 12. In this embodiment of the invention, the first opening connection part 13 of the adapter structure 1 is connected to the sub-body 24, and the second opening connection part 16 is connected to the flue 12. At the same time, when one end of the adapter structure 1 rotates relative to the sub-body 24 or the flue 12, the assembly position of the other end with the flue 12 or the sub-body 24 is adjustable, so that the adapter structure 1 is applicable to the sub-body 24 or the flue 12 with multiple positions according to the actual application scenario.

[0047] In this embodiment of the invention, the other end of the adapter structure 1 is provided with a second opening connection portion 16. The peripheral wall of the second opening connection portion 16 is a circular ring structure. The opening of the first opening connection portion 13 and the opening of the second opening connection portion 16 are partially misaligned and partially overlapped. The lower end of the first opening connection portion 13 is provided with a curved surface 15 extending obliquely towards the second opening connection portion 16. The curved surface 15 is a transitional connection between the lower edge of the peripheral wall of the first opening connection portion 13 and the upper edge of the peripheral wall of the second opening connection portion 16. The curved surface 15 extends from the lower edge of the first opening connection portion 13 to the opening of the second opening connection portion 16, forming a closed annular curved surface with the opening of the second opening connection portion 16. At the same time, the curved surface 15 is set as a smooth transition curved surface, which can also prevent oil fumes from accumulating at the adapter. The enclosed annular curved surface is more in line with gas flow, making it easier for oil fumes to pass through the adapter structure and be smoothly discharged from the unit.

[0048] The first opening connecting part 13 and the second opening connecting part 16 are staggered on both sides of the overlapping area, with the first opening connecting part 13 protruding to one side of the overlapping area and the second opening connecting part 16 protruding to the other side of the overlapping area. The straight wall of the first opening connecting part 13 is located on one side of the partial overlap and protrudes beyond the annular peripheral wall of the second opening connecting part 16 on the same side. A portion of the annular peripheral wall of the second opening connecting part 16 is located on the other side of the partial overlap and protrudes beyond the arc-shaped wall of the first opening connecting part 13 on the same side. That is, the peripheral walls of the first opening connecting part 13 and the peripheral walls of the second opening connecting part 16 are staggered in the horizontal direction. With the above arrangement, the adapter structure 1 can be used in public flues in different locations. It can be installed by simply rotating the adapter structure 1 around the central axis of the second opening connecting part 16 at different angles.

[0049] like Figure 1 As shown, in this embodiment of the invention, the diameter of the second opening connection portion 16 is slightly smaller than the diameter of the flexible connecting pipe 23. The outer side of the second opening connection portion 16 is fitted with the inner side of the flexible connecting pipe 23, and it is connected to the flexible connecting pipe 23. The interior of the curved surface 15 is a flow channel 18 for the circulation of oil fumes. The two ends of the curved surface 15 are respectively connected to the lower edge of the first opening connection portion 13 and the upper edge of the second opening connection portion 16.

[0050] In this embodiment of the invention, the intersection of the second opening connection 16 and the first opening connection 13 forms a flow channel 18 for the flow of oil fumes. The flow channel 18 is set as wide as possible so that in the case of heavy smoke in the kitchen, the oil fumes can flow smoothly into the sub-unit 24, and the oil fumes are prevented from remaining in the air in the kitchen for a long time.

[0051] Example 2

[0052] like Figures 1 to 4As shown, the difference between this embodiment and the previous embodiment is that it introduces a split-type range hood with the aforementioned adapter structure 1 installed. The range hood also includes a flue 12, one end of which is connected to a flexible connecting pipe 23, and the other end is connected to the top of the smoke collection hood 2. The adapter structure 1 and the flexible connecting pipe 23 are detachably connected. The first opening connection portion 13 is fixedly connected to the air inlet 25, and the second opening connection portion 16 has a circular structure and is connected to the flexible connecting pipe 23. The first opening connection portion 13 and the second opening connection portion 16 are integrally formed. The first opening connection portion 13 is located at the bottom of the split-type body 24 and is fixedly connected to the air inlet 25, so that the axis of the second opening connection portion 16 is collinear with the axis of the flexible connecting pipe 23. In this embodiment, the common flue is located on the left side of the user's home. By installing the adapter structure 1, the air outlet 17 of the split-type body 24 also faces to the left. When the user encounters a public flue on the right, the opening of the first opening connection part 13 has a limiting function. The straight wall and the arc wall correspond to the adapter 11. No other adapter tools are needed. The adapter structure 1 can be installed normally to ensure that the air outlet 17 faces the right, which is very convenient.

[0053] like Figures 1 to 4 As shown in the embodiment of the invention, the adapter structure 1 includes a first open connecting portion 13 at one end and a second open connecting portion 16 interleaved with the first open connecting portion 13. The first open connecting portion 13 has a groove 14 for connecting to the air inlet 25. Preferably, at least three grooves 14 are provided on the first open connecting portion, and each groove 14 is a through hole. An adapter 11 is provided at the air inlet 25. One end of the adapter 11 has an outwardly folded edge that fits tightly against the air inlet 25, and the other end is inserted into the first open connecting portion 13. The groove 14 and the adapter 11 are engaged, making the connection between the adapter structure 1 and the adapter 11 more secure. Preferably, the opening of the first open connecting portion 13 is slightly larger than the adapter 11, and the inner side of the first open connecting portion 13 fits tightly against the outer side of the adapter 11, so that the adapter structure 1 is fixedly installed at the air inlet 25.

[0054] In other embodiments, the first opening connection portion 13 can also be connected to the flexible connecting tube 23, and the second opening connection portion 16 can be connected to the adapter 11. Accordingly, the flexible connecting tube 23 is adapted to the irregular opening of the first opening connection portion 13.

[0055] There are many ways to directly connect the second opening connecting part 16 and the flexible connecting pipe 23, such as by clips or screws. Taking the example of an internal thread formed on the inner wall of the second opening connecting part 16 and an external thread formed on the outer wall of the flexible connecting pipe 23, the second opening connecting part 16 and the flexible connecting pipe 23 are connected by threads. Threaded connections are stable, reliable, and have good sealing performance, which can prevent oil fume leakage through the transition structure 1.

[0056] In this embodiment of the invention, an air inlet 25 is provided at the bottom of the sub-body 24, and an air outlet 17 is provided on the side. A first opening connecting part 13 extends protrudingly in the same direction as the air outlet 17, and a second opening connecting part 16 extends protrudingly in the direction of the air outlet 17. The openings of the first opening connecting part 13 and the second opening connecting part 16 are partially misaligned and partially overlapped. On the side of the overlapping part that is in the same direction as the air outlet 17, the first opening connecting part 13 protrudes beyond the second opening connecting part 16 on the same side. If the opening of the air outlet 17 faces the other side, the adapter structure 1 is rotated around the axis of the first opening connecting part 13 by a certain angle and inserted into the adapter 11. A portion of the peripheral wall of the second opening connecting part 16 protrudes beyond a portion of the arc-shaped peripheral wall of the first opening connecting part 13 on the same side.

[0057] When the sum of the thickness of the sub-unit 24, the length of the flue 12, and the thickness of the smoke hood 2 matches the ceiling height of the house, the transition structure 1 can be directly connected to the transition piece 11 and the flexible connecting pipe 23, respectively. When the ceiling height of the house is high, in order to minimize the impact of noise generated by the sub-unit 24 on the user, the sub-unit 24 is placed near the ceiling. At the same time, in order to ensure the smoke collection effect of the smoke hood 2, the position of the smoke hood 2 should be within a preset range from the stove. In this case, in order to meet the above requirements simultaneously, the total length of the range hood needs to be increased by the length of the flexible connecting pipe 23 so that the total length of the range hood matches the ceiling height of the house.

[0058] In this embodiment, the adapter structure 1 allows users to adjust the total length of the range hood according to their actual needs. This enables the range hood to adapt to various ceiling heights and makes full use of the ceiling height of the house, thereby minimizing the impact of noise generated by the fan assembly on the user.

[0059] In order to improve the smoothness of airflow in the fan assembly and minimize wind energy loss, the sub-unit 24 includes a volute and a fan. The fan is installed inside the volute, which is installed inside the sub-unit 24. The air inlet of the volute faces the air inlet 25, and the air outlet of the volute faces the air outlet 17.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
