Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a fan and a fume treatment device. Background Technology

[0002] A range hood includes a fan, which consists of a volute, an impeller, and a motor assembly. The volute has an air inlet, and the impeller is located inside the volute. The motor assembly drives the impeller to rotate. Based on centrifugal force, the fan draws gas in from the center and accelerates it through the high-speed rotating impeller before discharging it radially, thereby increasing the gas pressure and kinetic energy. As an important component of the fan, the volute is mainly used to guide airflow and provide space for the impeller to run.

[0003] Traditional volutes are usually made of all-metal. While all-metal volutes have high strength, they are also expensive and heavy. Existing volute technology often struggles to balance cost and performance, resulting in certain limitations in practical applications.

[0004] In addition, the motor assembly is fixed on the all-metal volute, which is made of metal. When the range hood is in use, the motor assembly collides with the all-metal volute, resulting in a lot of noise.

[0005] Therefore, there is an urgent need to design a new type of fan and fume treatment device to improve the problem of the volute casing being unable to balance cost and performance, as well as the problem of generating a lot of noise. Utility Model Content

[0006] One objective of this invention is to provide a fan that balances cost and performance, effectively reduces noise, lowers manufacturing costs, simplifies the structure, and improves assembly efficiency.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A fan, comprising:

[0009] Motor assembly;

[0010] The volute includes a front baffle, a rear baffle, and side panels. The front baffle and the rear baffle are arranged in the front-to-back direction and are located on both sides of the side panels. An air inlet is provided on the front baffle. The rear baffle and the side panels are formed into an integral structure by injection molding. The front baffle is made of metal. The motor assembly is fixedly connected to the integral structure.

[0011] As an optional solution, the rear panel includes a rear panel body and a first mounting part. The rear panel body is fixedly connected to the side panel, and the first mounting part is disposed on the rear panel body.

[0012] The motor assembly includes a mounting component and a motor mounted thereon, the mounting component being fixedly connected to the first mounting part.

[0013] As an alternative, the mounting component includes a mounting body and a second mounting part disposed thereon, wherein the motor is fixedly mounted on the mounting body, and the first mounting part and the second mounting part are fixedly connected.

[0014] As an alternative, at least two second mounting parts are provided, with the at least two second mounting parts arranged at circumferential intervals along the motor assembly, and each second mounting part corresponding to one first mounting part.

[0015] As an optional solution, the tailgate also includes:

[0016] The first reinforcing member is fixedly connected to the rear baffle body, and two adjacent first mounting parts are fixedly connected through the first reinforcing member.

[0017] As an alternative, the first mounting part is a ring-shaped reinforcing member, and the second mounting part is configured as at least two, with the at least two second mounting parts arranged at intervals along the circumference of the motor assembly and all fixedly connected to the ring-shaped reinforcing member.

[0018] As an alternative, the volute also includes:

[0019] The fastener securely connects the second mounting part to the first mounting part; and / or

[0020] A gasket is provided between the second mounting part and the first mounting part.

[0021] As an optional solution, the wind turbine also includes:

[0022] Mounting plate, which is fixedly connected to the side panel;

[0023] The connecting plate is fixedly connected to the mounting plate and the side panel, and the mounting plate, connecting plate, and side panel together form a receiving cavity; and

[0024] The noise reduction structure is located within the housing cavity.

[0025] As an optional solution, the wind turbine also includes:

[0026] The deflector plate is fixedly connected to the connecting plate and can direct the fumes towards the air inlet.

[0027] Another objective of this invention is to provide an oil fume treatment device that balances cost and performance, effectively reduces noise, lowers manufacturing costs, simplifies the structure, and improves assembly efficiency.

[0028] To achieve this objective, the present invention adopts the following technical solution:

[0029] An oil fume treatment device includes a main unit housing, which includes a housing and a fan as described above, the fan being disposed within the housing.

[0030] The beneficial effects of this utility model are:

[0031] The fan provided by this utility model includes a motor assembly and a volute. The volute includes a front baffle, a rear baffle, and side panels. The front and rear baffles are arranged along the front-to-back direction and located on both sides of the side panels. An air inlet is provided on the front baffle. The rear baffle and side panels are formed into a single structure by injection molding. The front baffle is made of metal. Firstly, by forming the rear and side panels into a single structure through injection molding, the cost is lower than that of traditional all-metal volutes. Secondly, because the baffles and side panels are formed into a single structure through injection molding and the front baffle is made of metal, the overall structural strength and stability of the volute can be effectively guaranteed. In summary, the volute can balance cost and performance.

[0032] In addition, the motor assembly is fixedly connected to the integrated structure, and the motor assembly is fixedly connected to the injection molded part. The injection molded part is softer than the metal part, and the injection molded part can dampen the motor assembly mounted on it to a certain extent, thereby effectively reducing the noise of the fan during use.

[0033] The oil fume treatment device provided by this utility model, by applying the above-mentioned fan, can balance cost and performance, and can also effectively reduce noise. Attached Figure Description

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and 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 drawings, not all of them.

[0050] 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.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of the embodiments disclosed herein, the terms "upper," "lower," "left," and "right," 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 the present invention. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no special meaning.

[0053] like Figure 1 As shown, the fume treatment device 1000 provided in this embodiment includes a main unit 100, a fume collection mechanism 200, and a check valve 300. The main unit 100 includes a housing 110 and a fan 120, which is disposed within the housing 110. The fume collection mechanism 200, the housing 110, and the check valve 300 are sequentially connected. The fume collection mechanism 200 has a fume inlet 210. When the fan 120 operates, it creates a negative pressure inside the housing 110. Fumes from the environment enter the housing 110 through the fume inlet 210 of the fume collection mechanism 200. The fumes are purified in the main unit 100, and the purified gas enters the external environment or subsequent pipelines through the check valve 300.

[0054] It should be noted that the fume treatment device 1000 in this disclosure embodiment can be a side-draft smoke machine, a European-style smoke machine, a "7-shaped" smoke machine, a top-mounted smoke machine, etc. All fume treatment devices 1000 capable of filtering and purifying fumes are within the protection scope of this disclosure embodiment.

[0055] like Figure 2 As shown, the fan 120 includes a volute 20, an impeller 70, and a motor assembly 10. The volute 20 has an air inlet 2111. The impeller 70 is disposed in the volute 20. The motor assembly 10 can drive the impeller 70 to rotate. Based on the centrifugal force, the fan 120 draws in gas from the air inlet 2111 and is accelerated by the high-speed rotating impeller 70 before being discharged radially, thereby increasing the pressure and kinetic energy of the gas.

[0056] like Figure 2 As shown, the fan 120 also includes a guide ring 40, which is located on the front side of the front baffle 21 and at the air inlet 2111. The guide ring 40 is designed to allow the oil fumes to enter the volute 20 more effectively and smoothly.

[0057] like Figure 2 As shown, the fan 120 also includes a rectifier mesh 50, which is located in front of the guide ring 40. The rectifier mesh 50 can filter oil fumes, reduce noise, and improve the oil fume extraction effect.

[0058] like Figure 2 As shown, the volute 20 is an important component of the fan 120. The volute 20 is mainly used to guide airflow and provide space for the impeller 70 to run.

[0059] Traditional volutes are typically made entirely of metal. While all-metal volutes offer high strength, they are also expensive and heavy. Existing volute technologies often struggle to balance cost and performance, limiting their practical applications. Furthermore, the motor assembly, which is primarily made of metal and is fixed to the all-metal volute, collides with it during operation, generating significant noise.

[0060] To solve the above problems, such as Figures 2-4 As shown, this embodiment of the present disclosure provides a volute 20, which includes a front baffle 21, a rear baffle 22 and a side panel 23. The front baffle 21 and the rear baffle 22 are arranged in the front-rear direction and are located on both sides of the side panel 23. An air inlet 2111 is provided on the front baffle 21. The rear baffle 22 and the side panel 23 are formed into an integral structure by injection molding. The front baffle 21 is made of metal.

[0061] First, since the rear baffle 22 and the side panel 23 are formed into an integral structure through injection molding, the cost is lower than that of the traditional all-metal volute. Second, since the rear baffle 22 and the side panel 23 are formed into an integral structure through injection molding and the front baffle 21 is made of metal, the overall structural strength and stability of the volute 20 can be effectively guaranteed. Third, the rear baffle 22 and the side panel 23 are formed into an integral structure through injection molding, eliminating the process of manufacturing the rear baffle 22 and the side panel 23 separately and assembling them together, reducing the manufacturing cost of the volute 20, simplifying the structure of the volute 20, and improving the assembly efficiency of the volute 20.

[0062] In summary, through the configuration of the volute 20 in this embodiment, the volute 20 can balance cost and performance, reduce manufacturing costs, simplify structure, and improve assembly efficiency.

[0063] In addition, such as Figure 4As shown, the motor assembly 10 is fixedly connected to the integrated structure, that is, the motor assembly 10 is fixedly connected to the injection molded part. The injection molded part is softer than the metal part. The injection molded part can dampen the motor assembly 10 mounted on it to a certain extent, thereby effectively reducing the noise of the fan 120 during use.

[0064] Specifically, such as Figures 2-4 As shown, the material of the integrated structure in this embodiment can be selected from ABS plastic, PC plastic, PET plastic, PE plastic, PA6 plastic, PA66 plastic, etc. Using the above-mentioned plastic materials can reduce the cost of the volute 20 and provide a certain shock absorption effect. It should be noted that different materials have different flame retardant ratings. The materials used in this embodiment are plastic materials with a flame retardant rating of V0 or V1, which can prevent the volute 20 from deforming or being damaged in a high-temperature oil fume environment, ensuring that the volute 20 always has a good service life and that the oil fume treatment device 1000 always has a good performance.

[0065] Specifically, the front baffle 21 can be made of metal materials such as aluminum alloy, galvanized sheet, or stainless steel, which can effectively improve the overall strength and hardness of the volute 20.

[0066] like Figure 3 As shown, the front baffle 21 includes a first reinforcing part 2112. The first reinforcing part 2112 effectively improves the strength and hardness of the front baffle 21, thereby effectively improving the strength and hardness of the volute 20. For example, the first reinforcing part 2112 can be a protrusion formed by stamping on the front baffle 21. This type of first reinforcing part 2112 has a simple structure and is easy to manufacture.

[0067] like Figure 3 and Figure 5 As shown, the front baffle 21 also includes a front baffle body 211 and a first limiting plate 212. The first limiting plate 212 is fixedly connected to the front baffle body 211. The side panel 23 also includes a second limiting plate 231. When the front baffle 21 is located on one side of the side panel 23, the first limiting plate 212 and the second limiting plate 231 abut against each other in the vertical direction and are fixedly connected, thereby achieving a good fixing effect between the front baffle 21 and the side panel 23, and also achieving a precise positioning effect between the front baffle 21 and the side panel 23.

[0068] like Figure 3 and Figure 5 As shown, a limiting groove 232 is also provided on the side panel 23. The lower end of the front baffle 21 is inserted into the limiting groove 232, which can further improve the accurate positioning of the front baffle 21 and the side panel 23, and also further improve the fixing effect of the front baffle 21 and the side panel 23.

[0069] like Figure 4 As shown, the rear baffle 22 includes a rear baffle body 221 and a first mounting part 222. The rear baffle body 221 is fixedly connected to the side panel 23. The first mounting part 222 is disposed on the rear baffle body 221. The motor assembly 10 includes a mounting part 11 and a motor 12 disposed thereon. The mounting part 11 is fixedly connected to the first mounting part 222. Through the cooperation between the mounting part 11 and the first mounting part 222, a stable connection between the motor assembly 10 and the rear baffle 22 can be achieved.

[0070] like Figure 4 As shown, the mounting component 11 includes a mounting body 111 and a second mounting part 112 disposed thereon. The motor 12 is fixedly mounted on the mounting body 111, and the first mounting part 222 is fixedly connected to the second mounting part 112. Through the cooperation of the second mounting part 112 and the first mounting part 222, precise alignment of the relative positions of the motor assembly 10 and the rear baffle 22 can be achieved, improving the installation efficiency and accuracy of the rear baffle 22 and the motor assembly 10.

[0071] like Figure 4 As shown, at least two second mounting portions 112 are provided, arranged at intervals along the circumference of the motor assembly 10. Each second mounting portion 112 corresponds one-to-one with a first mounting portion 222. By providing at least two second mounting portions 112, the mounting member 11 can provide stable support for the motor 12. For example, the number of second mounting portions 112 can be one, two, three, or more.

[0072] like Figure 4 As shown, the rear baffle 22 also includes a first reinforcing member 223, which is fixedly connected to the rear baffle body 221. Two adjacent first mounting parts 222 are fixedly connected through the first reinforcing member 223, thereby improving the overall strength and hardness of the rear baffle 22 and achieving a stable support effect for the motor assembly 10.

[0073] like Figure 4 As shown, the volute 20 also includes a fixing member 24, which fixes the second mounting part 112 to the first mounting part 222. The fixing member 24 ensures a secure connection between the second mounting part 112 and the first mounting part 222. For example, the fixing member 24 can be a screw, pin, snap-fit ​​assembly, magnetic assembly, etc., all capable of achieving a secure connection between the second mounting part 112 and the first mounting part 222.

[0074] In addition, the volute 20 also includes a gasket (not shown in the figure) disposed between the second mounting part 112 and the first mounting part 222. By providing the gasket, it is possible to prevent the second mounting part 112 and the first mounting part 222, which are fixed by the fastener 24, from becoming loose.

[0075] In an optional embodiment, the first mounting part can be an annular reinforcement (not shown in the figure), and at least two second mounting parts are arranged at intervals along the circumference of the motor assembly and are all fixedly connected to the annular reinforcement. The annular reinforcement has a simple overall structure and is easy to process. The annular reinforcement can achieve a relatively stable support effect for at least two second mounting parts.

[0076] like Figures 2-5 As shown, the volute 20 also includes a mounting plate 26, a connecting plate 27, and a noise reduction structure 30. The mounting plate 26 is fixedly connected to the side panel 23, and the connecting plate 27 is fixedly connected to both the mounting plate 26 and the side panel 23. The mounting plate 26, the connecting plate 27, and the side panel 23 together form a receiving cavity 28. The noise reduction structure 30 is disposed in the receiving cavity 28. The noise reduction structure 30 can absorb the noise generated inside the volute 20, reducing the noise generated by the fume treatment device 1000 during use. For example, the noise reduction structure 30 can be noise-reducing cotton, noise-reducing mesh, active noise reduction module, etc. All structures capable of achieving sound absorption and noise reduction are within the protection scope of this optional embodiment.

[0077] like Figure 5 As shown, the volute 20 also includes a flow guide plate 29, which is fixedly connected to the connecting plate 27. The flow guide plate 29 can guide the oil fumes toward the air inlet 2111, thereby effectively improving the air intake and oil fume filtration effect of the fan 120.

[0078] like Figure 5 and Figure 6 As shown, the volute 20 also includes a connector 291, and the outer casing 110 includes a top plate 1110. When the fan 120 is installed in the outer casing 110, the connector 291 abuts against and is fixedly connected to the top plate 1110, thus achieving a stable connection between the fan 120 and the outer casing 110. It should be noted that the operator can fix the fan 120 to itself outside the outer casing 110, facilitating quick and convenient installation of the fume treatment device 1000.

[0079] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
