Description

Technical Field

[0001] This utility model relates to the technical field of kitchen utensils, specifically to a fan cabinet assembly and a range hood. Background Technology

[0002] A range hood is a kitchen appliance used to purify the kitchen environment. It can quickly remove the exhaust gases produced by the stove and the fumes generated during cooking and exhaust them outdoors, thereby purifying the kitchen environment.

[0003] Current range hoods typically use an internal rotor motor as the power output component. The motor shaft of the internal rotor motor is connected to the motor housing via bearings, and the motor housing is connected to the volute via a support structure.

[0004] However, the vibrations generated by the internal rotor motor during operation can be transmitted through the motor shaft to the motor housing, and then through the motor housing to the volute, causing resonance in the volute cavity and significantly increasing the noise of the internal rotor motor. Furthermore, to ensure the robust connection between the motor housing and the volute, a complex support structure needs to be installed at the air inlet of the volute. This occupies a large area of ​​the airflow channel at the air inlet, resulting in a loss of air intake efficiency for the internal rotor motor and consequently reducing the smoke extraction effect of the range hood. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a blower assembly is provided, the technical solution of which is as follows.

[0006] The air handling unit assembly includes a cabinet, a fan, and a support frame. The cabinet encloses a receiving cavity. The fan has a volute and an external rotor motor. The volute is located within the receiving cavity and encloses a mounting cavity. The external rotor motor has a motor shaft and a rotating housing that rotates around the motor shaft. The external rotor motor is at least partially located within the mounting cavity. The support frame has a first connecting end and a second connecting end. The first connecting end is connected to the motor shaft, and the second connecting end is connected to the cabinet.

[0007] The fan housing assembly of this invention utilizes an external rotor motor as its power component. This external rotor motor features high torque and low speed, and its flared air inlet effectively increases the air intake area and efficiency. When applied to a range hood, it significantly improves the range hood's smoke extraction efficiency. Furthermore, the motor shaft of the external rotor motor can be connected to the cabinet via a bracket, shifting the motor's fixing point from the volute to the cabinet. This cuts off the transmission path of vibrations generated by the external rotor motor to the volute, while the cabinet effectively absorbs these vibrations, significantly reducing the noise of the fan housing assembly. Additionally, both ends of the motor shaft can extend from the mounting cavity and connect to the cabinet via the first connecting end of the bracket. This allows for a certain distance between the bracket and the volute's air inlet, eliminating the bracket's encroachment on the volute's air intake cross-section and effectively ensuring the external rotor motor's air intake efficiency, thereby improving the range hood's smoke extraction effect.

[0008] For example, at least one end of the motor shaft is connected to a bracket, such that at least one end of the motor shaft is connected to the cabinet. In this way, connecting at least one end of the motor shaft to the cabinet can firmly anchor the motor shaft to the cabinet, effectively preventing radial swaying of the rotating housing during rotation, and effectively improving the overall robustness of the fan assembly.

[0009] For example, the second connecting end is formed with a foot that makes surface contact with the cabinet. In this way, the foot can make surface contact with the cabinet, which not only increases the contact area between the bracket and the cabinet, thereby improving the stability of the connection between the two, but also efficiently transmits the vibration generated by the external rotor motor to the cabinet through the bracket, reducing the noise generated by the fan assembly.

[0010] For example, the cabinet is provided with positioning grooves, and the feet are positioned within these grooves, forming surface contact with the bottom of the grooves. Thus, by providing positioning grooves on the cabinet, the feet can be positioned, facilitating the installation of the bracket, and the feet can also be supported to prevent displacement of the bracket. Furthermore, the positioning grooves can improve the cabinet's bending resistance and structural strength, allowing the cabinet to better absorb vibrations generated by the external rotor motor.

[0011] For example, the cabinet has a recessed groove facing into the receiving cavity, and a positioning groove recessed from the bottom of the recess towards the outside of the receiving cavity. In this way, the groove provided on the cabinet can further enhance the structural strength of the connection between the support and the cabinet, thereby ensuring the stability and robustness of the air handling unit during operation.

[0012] For example, the bracket has a frame body and a connecting support member disposed on the outer edge of the frame body. The frame body is formed at a first connecting end, the motor shaft passes through the frame body, and the feet are formed at the end of the connecting support member away from the frame body. In this way, the frame body of the bracket can be connected to the motor shaft, and the connecting support member of the bracket can be connected to the cabinet. This not only ensures the compact structure of the bracket and effectively simplifies the connection structure of the bracket, but also reduces the volume of the bracket and further reduces the encroachment of the bracket on the air inlet section of the volute.

[0013] For example, the frame body is provided with a through hole for the motor shaft to pass through, and the frame body includes a plate portion and a boss portion protruding from the plate portion, with the through hole penetrating through the boss portion and the plate portion. Thus, when the through hole penetrates the boss portion, a hollow cavity can be formed within the boss portion. When the motor shaft passes through the through hole onto the plate portion, the inner wall surface of the hollow cavity can fit against the outer wall surface of the motor shaft, thereby increasing the contact area between the support and the motor shaft, and effectively ensuring the connection strength between the support and the motor shaft.

[0014] For example, the wall of the through hole has a flat limiting part, and the motor shaft has a flat mating part that abuts against the flat limiting part. In this way, the mating between the flat limiting part and the flat mating part not only improves the connection strength between the motor shaft and the bracket, but also prevents the motor shaft from rotating accidentally, thus ensuring the stability of the external rotor motor operation.

[0015] For example, a fastener is connected to the motor shaft, and the fastener abuts against the end face of the frame body away from the rotating housing to lock the bracket to the motor shaft. In this way, after the motor shaft is inserted into the bracket, the bracket can be locked to the motor shaft by the fastener, so as to avoid the bracket from accidentally falling off due to vibration generated by the external rotor motor during operation or due to external force, effectively improving the reliability and safety of the air handling unit assembly.

[0016] For example, the connecting support extends obliquely from the outer edge of the frame body in a direction away from the volute. In this way, the connecting support extending obliquely from the outer edge of the frame body can transmit the vibration acting on the frame body to the cabinet in an oblique direction, avoiding the situation where local stress concentration on the cabinet would occur when the vibration is transmitted to the cabinet in a vertical direction, which would lead to cabinet damage. Moreover, the connecting support and the frame body can be integrally formed, effectively ensuring the structural stability of the cabinet assembly.

[0017] For example, there are at least two connecting supports, which are spaced apart circumferentially on the frame body to form a claw-like structure. In this way, vibrations experienced by the frame body can be dispersed and evenly transmitted to the cabinet via the at least two connecting supports, avoiding structural damage to the support due to concentrated stress and greatly improving the load-bearing capacity and stability of the support. Furthermore, the claw-like structure of the support is simple, and its manufacturing cost and difficulty are relatively low.

[0018] For example, a reinforcing portion is formed by recessing the connecting support member in the direction of the centerline of the frame body; or, a reinforcing portion is formed by protruding the connecting support member in the direction away from the centerline of the frame body. In this way, a force can be applied to the connecting support member using mechanical equipment to make the surface of the connecting support member protrude or recess to form a reinforcing portion. The reinforcing portion can effectively improve the structural strength of the connecting support member, thereby further improving the stability and robustness of the air handling unit assembly, as well as the safety of use.

[0019] According to another aspect of the present invention, a range hood is also provided, including a smoke collection hood and a fan assembly as described above, wherein the smoke collection hood is disposed below the fan assembly.

[0020] The range hood of this utility model includes the fan housing assembly as described above. Since the fan housing assembly has the beneficial effects described above, the range hood including the fan housing assembly as described above will necessarily have the beneficial effects described above as well.

[0021] The advantages and features of this utility model will be described in detail below with reference to the accompanying drawings. Attached Figure Description

[0034] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0035] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0036] One embodiment of this utility model provides a blower assembly that can significantly reduce noise and improve air intake efficiency. The blower assembly according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the air handling unit assembly includes a cabinet 1, a fan 2, and a support 3. The cabinet 1 encloses a receiving cavity 11. The fan 2 has a volute 21 and an external rotor motor 22. The volute 21 is located within the receiving cavity 11 and encloses a mounting cavity 211. The external rotor motor 22 has a motor shaft 221 and a rotating housing 222 that rotates around the motor shaft 221. The external rotor motor 22 is at least partially located within the mounting cavity 211. The support 3 has a first connecting end 31 and a second connecting end 32. The first connecting end 31 is connected to the motor shaft 221, and the second connecting end 32 is connected to the cabinet 1.

[0038] The cabinet 1 can be enclosed to form a cavity 11 for housing components such as the volute 21 and the external rotor motor 22. The cabinet 1 can be made of a high-strength material to absorb the vibrations generated by the external rotor motor 22.

[0039] The external rotor motor 22 can be embedded in the mounting cavity 211 of the volute 21. When the rotating housing 222 rotates, it can draw gas into the volute 21 and discharge it through the air outlet of the volute 21. It is understood that the external rotor motor 22 and the volute 21 can be non-rigidly connected to avoid the vibration generated by the external rotor motor 22 from being transmitted to the volute 21.

[0040] The fan housing assembly of this invention can use an external rotor motor 22 as the power component. The external rotor motor 22 has the characteristics of high torque and low speed, and the air inlet of the external rotor motor 22 is flared, which can effectively improve the air intake area and air intake efficiency. When the external rotor motor 22 is applied to the range hood, it can significantly improve the smoke extraction efficiency of the range hood. In addition, the motor shaft 221 of the external rotor motor 22 can be connected to the cabinet 1 through the bracket 3, thereby transferring the fixing point of the external rotor motor 22 from the volute 21 to the cabinet 1, cutting off the transmission path of the vibration generated by the external rotor motor 22 to the volute 21. The cabinet 1 can effectively absorb the vibration generated by the external rotor motor 22, thereby significantly reducing the noise of the fan housing assembly. Furthermore, both ends of the motor shaft 221 can pass through the mounting cavity 211 and be connected to the cabinet 1 through the first connecting end 31 of the bracket 3. In this way, the bracket 3 can have a certain distance from the air inlet of the volute 21, eliminating the encroachment of the bracket 3 on the air inlet section of the volute 21, effectively ensuring the air intake efficiency of the external rotor motor 22, and thus improving the smoke extraction effect of the range hood.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, at least one end of the motor shaft 221 is connected to the bracket 3, so that at least one end of the motor shaft 221 is connected to the cabinet 1.

[0042] For example, there can be two brackets 3, and the two ends of the motor shaft 221 can be connected to the two brackets 3 respectively, so as to connect the external rotor motor 22 to the two side walls of the cabinet 1. This avoids the centrifugal force generated by the rotating shell 222 when it is connected to a single side wall of the cabinet 1, which would affect the stability of the connection between the motor shaft 221 and the cabinet 1.

[0043] In the above embodiment, connecting at least one end of the motor shaft 221 to the cabinet 1 can firmly anchor the motor shaft 221 to the cabinet 1, effectively preventing the radial sway of the rotating outer shell 222 when it rotates, and effectively improving the overall robustness of the air handling unit.

[0044] In some embodiments, such as Figure 3 and Figure 4 As shown, the second connecting end 32 has a foot 321, which makes surface contact with the cabinet body 1.

[0045] The shape of the foot 321 can be plate-shaped, and the plate-shaped foot 321 can fit tightly against the cabinet 1 and form surface contact.

[0046] The foot 321 may have connection holes for screws or bolts, which can be used to securely connect the bracket 3 to the cabinet 1.

[0047] In the above embodiment, the foot 321 can form a surface contact with the cabinet 1, which not only increases the contact area between the bracket 3 and the cabinet 1, thereby improving the stability of the connection between the two, but also efficiently transmits the vibration generated by the external rotor motor 22 to the cabinet 1 through the bracket 3, reducing the noise generated by the air handling unit.

[0048] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, a positioning groove 12 is provided on the cabinet body 1, and the foot 321 is located in the positioning groove 12 and forms a surface contact with the bottom of the positioning groove 12.

[0049] The positioning groove 12 can be formed by protruding from the surface of the cabinet 1 in a direction away from the receiving cavity 11. The size of the positioning groove 12 can be adapted to the size of the foot 321 so that when the foot 321 is placed in the positioning groove 12, the groove wall of the positioning groove 12 can provide support and limit the foot 321, effectively preventing the vibration generated by the external rotor motor 22 from causing the bracket 3 to shift.

[0050] In the above embodiment, by providing a positioning groove 12 on the cabinet 1, not only can the feet 321 be positioned, thus facilitating the installation of the bracket 3, but the feet 321 can also be supported to prevent displacement of the bracket 3. In addition, the positioning groove 12 can improve the bending resistance and structural strength of the cabinet 1, so that the cabinet 1 can better absorb the vibration generated by the external rotor motor 22.

[0051] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the cabinet 1 has a groove 13 recessed into the receiving cavity 11, and a positioning groove 12 recessed from the bottom of the groove 13 outwards from the receiving cavity 11.

[0052] The groove 13 can be formed by protruding from the surface of the cabinet 1 toward the receiving cavity 11, and the positioning groove 12 can be formed by protruding from the bottom of the groove 13 toward the direction away from the receiving cavity 11. The projection of the bracket 3 toward the plane of the cabinet 1 can be located within the groove 13 to improve the structural strength of the connection between the bracket 3 and the cabinet 1.

[0053] In the above embodiment, the groove 13 provided on the cabinet 1 can further enhance the structural strength of the connection between the support 3 and the cabinet 1, thereby ensuring the stability and robustness of the air handling unit during operation.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the bracket 3 has a frame body 33 and a connecting support 34 disposed on the outer edge of the frame body 33. The frame body 33 is formed at the first connecting end 31, the motor shaft 221 passes through the frame body 33, and the foot 321 is formed at the end of the connecting support 34 away from the frame body 33.

[0055] The frame body 33 can be plate-shaped, and a connecting support 34 can be provided along the outer edge of the plate-shaped frame body 33. The frame body 33 and the connecting support 34 can be detachably connected or integrally formed. The detachable connection can include plug-in connection or adhesive connection, etc., and this application does not make specific limitations in this regard.

[0056] In the above embodiment, the frame body 33 of the bracket 3 can be connected to the motor shaft 221, and the connecting support 34 of the bracket 3 can be connected to the cabinet 1. This not only ensures that the structure of the bracket 3 is compact and effectively simplifies the connection structure of the bracket 3, but also reduces the volume of the bracket 3 and further reduces the encroachment of the bracket 3 on the air inlet section of the volute 21.

[0057] In some embodiments, such as Figure 3 and Figure 4As shown, the frame body 33 is provided with a through hole 331 for the motor shaft 221 to pass through, and the frame body 33 includes a plate portion 332 and a boss portion 333 protruding from the plate portion 332. The through hole 331 passes through the boss portion 333 and the plate portion 332.

[0058] The inner contour of the through hole 331 can be adapted to the outer contour of the motor shaft 221 so that the motor shaft 221 can be securely inserted into the through hole 331.

[0059] In the above embodiment, when the through hole 331 penetrates the boss portion 333, a hollow cavity can be formed in the boss portion 333. When the motor shaft 221 passes through the through hole 331 onto the plate portion 332, the inner wall surface of the hollow cavity can fit against the outer wall surface of the motor shaft 221, thereby increasing the contact area between the bracket 3 and the motor shaft 221, thus effectively ensuring the connection strength between the bracket 3 and the motor shaft 221.

[0060] In some embodiments, such as Figure 3 As shown, the wall of the through hole 331 has a flat limiting part 3311, and the motor shaft 221 has a flat fitting part that abuts against the flat limiting part 3311.

[0061] The number of straight limiting parts 3311 can be multiple, and multiple straight limiting parts 3311 can be formed at intervals on the wall of the through hole 331. The outer wall surface of the motor shaft 221 can be formed with a straight mating part corresponding to the straight limiting part 3311. When the motor shaft 221 is inserted into the through hole 331, the straight limiting part 3311 and the straight mating part can fit together. In this way, not only can the contact area between the motor shaft 221 and the bracket 3 be increased, thereby improving the strength and reliability of the connection between the two, but the motor shaft 221 can also be prevented from rotating around its circumference, thereby affecting the connection between the bracket 3 and the cabinet 1.

[0062] In the above embodiment, the cooperation between the flat limiting part 3311 and the flat mating part can not only improve the connection strength between the motor shaft 221 and the bracket 3, but also prevent the motor shaft 221 from rotating unexpectedly, thus ensuring the stability of the operation of the external rotor motor 22.

[0063] In some embodiments, such as Figure 7 , Figure 8 and Figure 9 As shown, a fastener 4 is connected to the motor shaft 221. The fastener 4 abuts against the end face of the frame body 33 away from the rotating outer shell 222 to lock the bracket 3 to the motor shaft 221.

[0064] The fastener 4 can be a nut. The end of the motor shaft 221 can be formed with a thread that matches the nut. Through the threaded connection between the fastener 4 and the motor shaft 221, the bracket 3 can be prevented from accidentally falling off due to force.

[0065] In the above embodiment, after the motor shaft 221 is inserted into the bracket 3, the bracket 3 can be locked onto the motor shaft 221 using fasteners 4, so as to avoid the vibration generated by the external rotor motor 22 during operation or the bracket 3 from accidentally falling off due to external force, which effectively improves the reliability and safety of the air handling unit.

[0066] In some embodiments, such as Figure 3 and Figure 4 As shown, the connecting support 34 extends obliquely from the outer edge of the frame body 33 in a direction away from the volute 21.

[0067] In an embodiment not shown, the bracket 3 may be bowl-shaped, with the bottom portion of the bracket 3 being constructed as the bracket body 33 and the bowl wall portion being constructed as the connecting support member 34.

[0068] In the above embodiment, the connecting support 34 extending obliquely from the outer edge of the frame body 33 can transmit the vibration acting on the frame body 33 to the cabinet 1 in an oblique direction, avoiding the situation where the cabinet 1 is damaged due to local stress concentration when the vibration is transmitted to the cabinet 1 in a vertical direction. Moreover, the connecting support 34 and the frame body 33 can be integrally formed, effectively ensuring the structural stability of the cabinet 1 assembly.

[0069] In some embodiments, such as Figure 3 and Figure 4 As shown, there are at least two connecting support members 34, and the at least two connecting support members 34 are spaced apart in the circumferential direction of the frame body 33 to form a claw-like structure.

[0070] In the above embodiments, the vibrations experienced by the frame body 33 can be dispersed and evenly transmitted to the cabinet 1 through at least two connecting support members 34, avoiding structural damage to the support 3 due to concentrated force and greatly improving the load-bearing capacity and stability of the support 3. Furthermore, the support 3 with its claw-like structure has a simple structure, and its manufacturing cost and difficulty are relatively low.

[0071] In some embodiments, such as Figure 3 and Figure 4 As shown, a reinforcing portion 341 is recessed on the connecting support member 34 in the direction of the center line of the frame body 33; or, a reinforcing portion 341 is protruded on the connecting support member 34 in the direction away from the center line of the frame body 33.

[0072] In the above embodiments, mechanical equipment can be used to apply force to the connecting support 34 to make the surface of the connecting support 34 protrude or indent to form a reinforcing part 341. The reinforcing part 341 can effectively improve the structural strength of the connecting support 34, thereby further improving the stability and robustness of the air handling unit assembly, as well as the safety of use.

[0073] According to another aspect of the present invention, a range hood is also provided, including a smoke collection hood and a fan assembly as described above, wherein the smoke collection hood is disposed below the fan assembly.

[0074] The fume hood can be connected to the cabinet 1. When the external rotor motor 22 rotates, it can create a negative pressure in the receiving cavity 11, thereby drawing the oil fumes from the external environment into the receiving cavity 11 through the fume hood, and then allowing the oil fumes in the receiving cavity 11 to enter the volute 21 and be discharged through the air outlet of the volute 21.

[0075] The range hood of this utility model includes the fan housing assembly as described above.
