Example 1
As shown in fig. 1-4, the fan assembly provided by the utility model is arranged above the fume collecting hood, can generate negative pressure, and acts on the left fume inlet and the right fume inlet of the fume collecting hood, so that fume is sucked from outside to inside.
Specifically, the fan assembly includes a fan 100, a rotational drive mechanism 200, and a housing 300. The fan 100 may have a volute, and air inlets are formed on both left and right sidewalls of the volute. The rotation driving mechanism 200 may be, but not limited to, a push rod motor by which it is rotated. The housing 300 is fixedly connected to the fume collecting hood.
The fan 100 is rotatably connected with the housing 300, a left air inlet area is formed between the left side of the fan 100 and the housing 300, and a right air inlet area is formed between the right side of the fan 100 and the housing 300. Conventionally, the blower 100 is installed at a middle position in the left-right direction of the housing 300. The rotation driving mechanism 200 is connected to the blower 100, and is used for driving the blower 100 to rotate to the left or right, so that the area a of the air inlet of the left air inlet area and the area b of the air inlet of the right air inlet area are changed. The total of the area a of the air inlet of the left air inlet area and the area b of the air inlet of the right air inlet area is a fixed value, one of which is decreased and the other is increased, and thus, the rotation of the blower 100 can directly cause the change of the air inlet quantity on the left and right sides. It should be noted that, the air inlet of the left air inlet area refers to an opening formed by a horizontal gap between the left side edge of the bottom of the blower 100 and the left side wall of the housing 300, and the fume in the fume collecting hood flows upward through the opening and enters the left fume inlet of the blower, and similarly, the air inlet of the right air inlet area refers to an opening formed by a horizontal gap between the right side edge of the bottom of the blower 100 and the right side wall of the housing 300.
Under the condition that the range hood faces a single-range cooking, if a left cooking range is opened, the left cooking range has higher oil smoke concentration, and at the moment, the fan 100 can be driven by the rotary driving mechanism 200 to rotate to the right side, as shown in fig. 3, so that the area a of an air inlet of a left air inlet area is increased, and the area b of an air inlet of an opposite right air inlet area is reduced, thereby being beneficial to the smoke inlet of the left air inlet on the smoke collecting hood; on the contrary, if the right cooking stove is opened during cooking, the fan 100 can be driven by the rotation driving mechanism 200 to rotate to the left side, as shown in fig. 4, so that the area a of the air inlet of the left air inlet area is reduced, and the area b of the air inlet of the opposite right air inlet area is increased, which is beneficial to the smoke inlet of the right smoke collecting cover. The air inlet quantity of the left air inlet area and the right air inlet area is regulated according to the oil smoke of the left and right stoves, so that the smoking effect is improved.
In this embodiment, the blower 100 rotates about a first axis of rotation that extends in a vertical direction. The first rotation axis may be a physical axis or not.
The casing 300 is provided with a casing flange 410, and the fan 100 is provided with a fan flange 420, wherein the cross section of the interface between the casing flange 410 and the fan flange 420 is circular. The housing flange 410 and the blower flange 420 are coaxially arranged, the blower flange 420 is suspended on the housing flange 410, and the blower flange 420 can rotate relative to the housing flange 410 by rotating the driving mechanism 200. It should be noted that, the fan flange 420 is connected with the air outlet of the fan 100, the housing flange 410 is connected with the outlet on the top of the housing 300, the lower end of the housing flange 410 is connected with the fan flange 420, and the upper end of the housing flange 410 is connected with the indoor air duct to guide the oil smoke into the public flue.
The housing flange 410 has an annular groove 411 therein which opens toward the middle; the fan flange 420 has an outwardly projecting annular skirt 421 thereon; the annular skirt 421 is located in the annular groove 411, and the annular skirt 421 rotates in the annular groove 411. In order to improve the sealing degree and reduce the air leakage, a sealing structure is arranged between the annular groove 411 and the annular skirt 421, and the sealing structure can be a sealing ring 430.
To improve stability, the housing 300 has a support structure attached to the bottom of the fan 100. Specifically, the support structure includes a support frame 510, and a support shaft 520 fixedly connected to the support frame 510, where the support shaft 520 is coaxial with the housing flange 410 and the fan flange 420, respectively. The bottom surface of the scroll case of the blower 100 may be provided with a socket connected to the support shaft 520.
Example 2
As shown in fig. 5 to 7, unlike the rotation method of embodiment 1, the blower 100 of the present embodiment rotates with the housing 300 through the second rotation shaft, which extends in the front-rear direction. In this embodiment, the second rotating shaft is a solid shaft structure, two ends of the second rotating shaft are respectively connected with the front wall and the rear wall of the housing 300, and the fan 100 is suspended on the second rotating shaft and can swing left and right.
In order to realize the connection between the air outlet of the fan 100 and the check valve on the housing 300, the air outlet of the fan 100 is communicated with the smoke outlet of the housing 300 through the flexible pipe 600, so that the influence of the swinging fan 100 on the conduction of smoke is avoided.
The housing 300 is connected with a chute 710, the chute 710 is connected with the bottom of the motor through a connecting rod 720, one end of the connecting rod 720 is rotationally connected with the motor, and the other end of the connecting rod 720 is slidably connected in the chute 710. When the fan 100 swings, the connecting rod 720 slides in the chute 710, and the connecting rod 720 plays a certain supporting role on the fan 100.
The range hood provided by the utility model comprises the fan assembly. Because the range hood provided by the utility model cited the fan assembly, the range hood provided by the utility model also has the advantage of the fan assembly.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
