In an embodiment, the two opposite sides of the centrifugal fan 200 are respectively formed with an air inlet 21, and an air inlet gap is formed between the side where the air inlet 21 is formed and the corresponding cavity wall of the cavity 111. Specifically, the air inlet 21 is formed in each of the first side surface 23 and the second side surface 24 of the centrifugal fan 200, and air inlet gaps are formed between the first side surface 23 and the cavity wall of the cavity 111 and between the second side surface 24 and the cavity wall of the cavity 111, so that air is simultaneously fed into the two sides of the centrifugal fan 200, and the air volume can be effectively increased.

In an embodiment, the two first air outlets 112 are respectively disposed at the left and right sides of the cavity 111, the cavity 111 is in a left-right symmetric structure, and the rotation center of the centrifugal fan 200 is on the symmetry line of the cavity 111. Thus, the distance between the center of the centrifugal fan 200 and the two first air outlets 112 is substantially the same, and thus the air volume discharged from the two first air outlets 112 is substantially the same.

Referring to fig. 6 and fig. 7, in an embodiment, the centrifugal fan 200 includes a centrifugal volute 20 and an air duct 60 connected to each other, the centrifugal volute 20 has a second air outlet, one end of the air duct 60 is connected to the second air outlet, and the other end is the air outlet 22. In this embodiment, the air duct 60 is connected to the second air outlet in a butt joint manner, i.e., the air duct is surrounded at the outer side or the inner side of the second air outlet.

Since the centrifugal fan 200 itself has an irregular shape of the centrifugal scroll 20, the distances from the center are different between the left and right sides. Therefore, in order to ensure that the air output of the first air outlets 112 on the left side and the right side are basically consistent, and on the premise of not changing the structure of the centrifugal volute 20 (the structure of the centrifugal volute 20 does not need to be changed, and a mold for molding the centrifugal volute 20 does not need to be changed, so that the production cost can be reduced), a section of air duct 60 is additionally arranged, so that the distance from the air outlet 22 of the centrifugal fan 200 to the corresponding first air outlet 112 can be basically the same before or after the installation direction of the centrifugal fan 200 is changed, and therefore, the air output from any one first air outlet 112 is basically consistent, and the situation that the air output on one side is less does not occur.

In this embodiment, the air duct 60 and the centrifugal volute 20 may be connected by screws or snap-fit connection, or both of them may be fixed by welding. Similarly, the air duct 60 and the frame 11 may be fixed by screws or snap-fit connection, or both.

The end surface of the air pipe 60 departing from the second air outlet is provided with a second mounting flange 62, and the second mounting flange 62 is abutted to the cavity wall of the cavity 111.

The left side and the right side of the coaming 117 are respectively provided with a communication port, and the communication ports communicate the centrifugal fan 200 with the corresponding first air outlet 112.

In this embodiment, the shroud 117 has a rearward opening covered by the rear sidewall 116 and an upward opening in communication with the flue in the head 12. Optionally, the upper end of the enclosing plate 117 is inclined so that the upward opening is gradually enlarged from bottom to top, thereby guiding the smoke.

The air duct 60 is abutted against the surrounding plate 117, and the air duct 60 is disposed around the communication opening, so that the flue gas is directly guided to the first air outlet 112 from the communication opening. Note that the axes of the first air outlet 112, the communication port, and the air outlet 22 are coincident.

By providing the baffle 117, the chamber 111 can be defined as a smaller chamber 111, which is beneficial for gathering the flue gas and discharging the flue gas through the centrifugal fan 200 quickly. In addition, centrifugal fan 200 may be positioned at the bottom of shroud 117, supported by shroud 117.

Referring to fig. 3, a check valve 70 is disposed between the shroud 117 and the left sidewall 113, or a check valve 70 is disposed between the shroud 117 and the right sidewall 114; the check valve 70 is connected to the centrifugal fan 200, and the check valve 70 communicates the communication port with the first air outlet 112. The check valve 70 can prevent the smoke from flowing back into the centrifugal fan 200 after being discharged from the first air outlet 112. When the discharge port 22 is communicated with the first discharge port 112 on the left side, the check valve 70 is disposed between the left side wall 113 and the shroud 117. Similarly, when the exhaust port 22 is communicated with the right first air outlet 112, the check valve 70 is disposed between the right sidewall 114 and the shroud 117.

In one embodiment, the integrated stove further comprises a blocking cover (not shown) for selectively blocking one of the two first air outlets 112 which is not communicated with the air outlet 22. Specifically, when the air outlet 22 communicates with the first air outlet 112 on the left side, the blocking cover blocks the first air outlet 112 on the right side, and vice versa.

Referring to fig. 6 and 12, the structure of the centrifugal fan 200 is described in detail as follows:

the centrifugal fan 200 includes:

a centrifugal volute 20 formed with an air inlet 21;

a centrifugal impeller 40 installed in the centrifugal scroll 20;

the outer rotor motor 30 comprises a stator 32 and a rotor 31 matched with the stator 32, and the rotor 31 is connected with the centrifugal impeller 40; and the number of the first and second groups,

a bracket respectively connected to the stator and the centrifugal scroll 20.

Wherein, an air inlet 21 is formed at one side or both sides of the centrifugal volute 20. The centrifugal impeller 40 includes a mounting plate 42 and a plurality of blades 41 provided on the mounting plate 42, the mounting plate 42 has a disk-shaped configuration, and the plurality of blades 41 are spaced apart from each other along a peripheral edge of the mounting plate 42.

The outer rotor motor 30 is used for driving the centrifugal impeller 40 to rotate, and specifically, the rotor 31 is connected with the mounting disc 42.

In the embodiment that the air inlets 21 are respectively formed at two sides of the centrifugal volute, the brackets 50 are respectively installed at the two air inlets 21, and two ends of the stator 32 are respectively connected and fixed with the corresponding brackets 50. In the embodiment where the air inlet 21 is formed at one side of the centrifugal scroll, the bracket is only arranged at the side where the air inlet is formed.

Referring to fig. 9, the rotor 31 of the outer rotor motor 30 is sleeved outside the stator 32, the rotor 31 is connected to the mounting plate 42, and when the outer rotor motor 30 is started, the rotor 31 directly drives the mounting plate 42 to rotate, so as to drive the centrifugal impeller 40 to rotate. The stator 32 is connected to the centrifugal volute 20 through the bracket 50, and the bracket 50 has an effect of supporting the outer rotor motor 30, and when the stator 32 is kept in a stable state, the positions of the rotor 31 and the centrifugal impeller 40 are relatively determined.

The bracket 50 is used for being mounted on the centrifugal volute 20 and supporting the outer rotor motor 30, when the centrifugal fan is manufactured, the bracket 50 is mounted at the air inlet 21 at two sides, and two ends of the stator 32 are respectively connected with the two brackets 50, so that the stator 32 is fixed on the centrifugal volute 20.

In the operation process of the motor, because the rotor 31 deviates from the center of the rotating magnetic field, the air gap between the stator 32 and the rotor 31 is uneven, and unbalanced force and moment are easily generated, when the motor directly fixed on the centrifugal volute 20 drives the centrifugal impeller 40 to rotate, the vibration generated by the motor is directly transmitted to the centrifugal volute 20, and vibration noise is generated; in the operation process of the centrifugal fan 200, the noise is amplified along with the air duct, so that the operation noise of the centrifugal fan 200 is increased continuously. In this embodiment, since the rotor 31 is connected to the centrifugal impeller 40, when the outer rotor motor 30 operates, the centrifugal impeller 40 only interacts with the rotor 31, and the generated vibration noise is not directly transmitted to the centrifugal scroll 20, thereby reducing the operation noise of the centrifugal fan 200.

Because the rotor 31 is directly connected to the mounting disc 42 of the centrifugal impeller 40, when the outer rotor motor 30 operates, the rotor 31 directly drives the centrifugal impeller 40 to rotate, so that transmission loss can be reduced, and the work efficiency of the outer rotor motor 30 can be improved.

During the rotation of the rotor 31 of the motor, centrifugal forces are generated due to the uneven distribution of mass of the rotor 31 with respect to the axis of the motor, and the unbalanced centrifugal forces acting on the bearings of the rotor 31 may cause vibrations. When mounting, the outer rotor motor 30 and the centrifugal impeller 40 may be fixed and then adjusted for dynamic balance, and may be integrally mounted to the bracket 50 after the adjustment for dynamic balance. By first performing dynamic balance adjustment on the outer rotor motor 30, the rotor 31 reaches the minimum value of the residual unbalance amount, so that the ratio of the corrected unbalance amount of the rotor 31 to the initial unbalance amount thereof is reduced, the balance efficiency of the rotor 31 is improved, and the support vibration caused by the unbalance of the rotor 31 is reduced.

After the outer rotor motor 30 is adjusted in dynamic balance, the balance efficiency of the rotor 31 is improved, and the overall noise of the outer rotor motor 30 during operation is kept low. Then, the outer rotor motor 30 is connected to the centrifugal volute 20, so that the problem of large overall vibration caused by the accumulation of manufacturing and installation tolerances can be avoided, and the vibration noise generated by the centrifugal fan 200 can be further reduced.

After the dynamic balance debugging is completed, the bracket 50 is connected with the centrifugal volute 20, and when the outer rotor motor 30 operates, the vibration quantity transmitted to the centrifugal volute 20 is reduced, so that the overall vibration of the centrifugal fan 200 can be effectively reduced, the operation noise is reduced, and the user experience is improved.

The bracket 50 may be detachably connected to the centrifugal volute 20, and after the dynamic balance adjustment of the outer rotor motor 30 is completed, the bracket 50 is fixedly connected to the centrifugal volute 20. The bracket 50 may also be integrally formed with the centrifugal volute 20. After the stator 32 and the bracket 50 are installed, the connection portion of the stator 32 and the bracket 50 may be located on the axis of the outer rotor motor 30, so as to reduce the shielding of the bracket 50 on the portion of the air inlet 21, which is beneficial to increasing the effective air inlet area of the air inlet 21.

The bracket 50 may be installed inside the air inlet 21 of the centrifugal scroll 20, so as to reduce the overall volume of the centrifugal fan 200, and when the centrifugal fan 200 is installed in an integrated kitchen, the overall volume of the integrated kitchen can be reduced, and the space utilization rate can be improved. The bracket 50 may be installed outside the air inlet 21, and is connected and fixed with the outer surface of the centrifugal volute 20, so that the connecting portion of the bracket 50 and the centrifugal volute 20 does not block the air inlet 21, thereby preventing the air inlet 21 from generating turbulent flow and reducing the wind resistance of the air inlet 21. The bracket 50 may also be arched toward the outside of the air inlet 21 of the centrifugal fan 200, and when the outer rotor motor 30 is in operation, the bracket 50 can buffer the vibration generated by the outer rotor motor 30, so as to further reduce the vibration noise of the centrifugal fan 200.

Since the centrifugal fan 200 employs the outer rotor motor 30, the volume of the driving part of the centrifugal fan 200 can be effectively reduced. The outer rotor motor 30 shields the air inlet 21 and the wheel cavity of the centrifugal fan 200 relatively less, which is beneficial to increasing the effective air inlet area of the centrifugal fan 200, and further improves the operation efficiency of the centrifugal fan 200.

Referring to fig. 6, 7 and 8, in order to reduce the volume of the centrifugal fan 200, in an embodiment of the present invention, a wheel cavity is formed in the middle of the centrifugal impeller 40, and the external rotor motor 30 is installed in the wheel cavity to reduce the volume of the centrifugal fan 200. Because of the adoption external rotor electric machine 30, its volume is less, when installing it when taking turns the intracavity, shared volume is less, can increase the air inlet area, increases the amount of wind and the wind pressure of complete machine.

Because the effective air inlet area of the centrifugal fan 200 is increased and the shielding of the outer rotor motor 30 to the wheel cavity of the centrifugal impeller 40 is reduced, the air inlet of the centrifugal impeller 40 can be more uniform, thereby reducing the air flow interference and reducing the turbulence noise. When the air flow enters the wheel cavity from the air inlet 21, the blocking of the air flow entering the wheel cavity by the outer rotor motor 30 is reduced, so that the distribution of the air flow in the wheel cavity is more uniform, the air inlet of the centrifugal impeller 40 is balanced, the turbulent flow caused by uneven air flow is reduced, the turbulent flow noise is reduced, the noise of the whole machine is reduced, and the noise reduction effect is realized.

In an embodiment of the present invention, the mounting plate 42 is disposed in the wheel cavity, the rotor 31 is connected to the mounting plate 42, at this time, the mounting plate 42 is used as a middle plate in the wheel cavity, the rotor 31 is located in the wheel cavity, so that the rotor 31 does not occupy the external space of the centrifugal fan 200, thereby helping to reduce the overall volume of the centrifugal fan 200.

In another embodiment of the present invention, the mounting plate 42 is close to one side of the air inlet 21, the mounting plate 42 is used as the end plate of the centrifugal fan 40, the middle portion of the mounting plate 42 protrudes into the wheel cavity, the rotor 31 is connected to the portion of the mounting plate 42 protruding into the wheel cavity, so as to drive the centrifugal fan 40 to rotate and reduce the volume of the centrifugal fan 200.

The two shaft ends 33 are respectively coaxial with the stator 32, so that after the stator 32 is installed, the connecting part of the bracket 50 and the stator 32 is coaxial with the stator 32, and further, the stator 32 can be kept in a balanced state, and vibration caused by uneven stress of the stator 32 is avoided.

Referring to fig. 10 and 12, in an embodiment of the present invention, the shaft end 33 is provided with a connecting member 34, the bracket 50 is provided with a mounting hole 54 for receiving the connecting member 34, and the shaft end 33 is connected to the bracket 50 through the connecting member 34. The connecting piece 34 is used for fixing the shaft end 33 so as to match the shaft end 33 with the bracket 50.

The holder main body 51 is an elongated structure, the support end 53 and the connection end 52 may be two ends of the holder main body 51, and the support end 53 is used for being connected and fixed with the centrifugal scroll 20. The connecting end 52 of the bracket main body 51 is connected with the adjacent bracket main body 51, in the projection of the bracket main body 51 on the plane perpendicular to the axis of the centrifugal impeller 40, the bracket main body 51 and the extension line thereof do not intersect with the axis of the stator 32, and the connecting end 52 and the axis of the stator 32 are arranged in a staggered manner.

The holder main bodies 51 are arranged in an annular array with the axis of the centrifugal impeller 40 as the center, so that the holder main bodies 51 are arranged in a regular form, and the airflow enters the impeller cavity from a channel formed between the adjacent holder main bodies 51.
