The side of fan 200 is provided with circular shape fresh air inlet 210, and water conservancy diversion piece 300 is located the circumference outside of fresh air inlet 210, water conservancy diversion piece 300 is used for leading the air current that flows in from the air inlet to fan 200 has the one side of fresh air inlet 210, and different with prior art, water conservancy diversion piece 300 is followed the circumference of fresh air inlet 210 is crooked, that is to say, in the length direction of water conservancy diversion piece, and water conservancy diversion piece 300 is crooked towards the one side of keeping away from fresh air inlet 210.
When the fan 200 is started, the airflow flows from the air inlet to the direction of the fan 200, the airflow first contacts the flow guide member 300 during movement, the spreading direction of the airflow is changed under the blocking of the flow guide member 300, and the airflow flows towards the side of the fan 200 with the air inlet holes 210 until the airflow is sucked into the air inlet holes 210. Different from the prior art, in the present solution, the air guide member 300 is bent along the circumferential direction of the air inlet holes 210, and thus, both ends of the air guide member 300 are bent toward the air inlet holes 210, respectively. In the prior art, the diversion member is straight, the extending direction of the diversion member is perpendicular to the axis of the air inlet hole, the difference between the distance from the air flow flowing out from the middle of the diversion member 300 to the air inlet hole 210 and the distance from the air flow flowing out from the end of the diversion member 300 to the air inlet hole 210 is larger, compared with the prior art, the difference between the distance from the two ends of the diversion member 300 to the air inlet hole 210 is closer to the edge of the air inlet hole 210, and the difference between the distance from the air flow flowing out from the middle of the diversion member 300 to the air inlet hole 210 and the distance from the air flow flowing out from the end of the diversion member 300 to the air inlet hole 210 is smaller than the difference in the prior art, so that in the circumferential direction of the air inlet hole 210, the difference of the air flow velocity at each position between the diversion member 300 and the air inlet hole 210 is smaller.
In other embodiments, the number of the air inlet holes 210 of the existing fan 200 may be one, and the air guide 300 has a guide surface inclined with respect to the vertical direction for guiding the air flow, in which the air guide 300 only plays a role in guiding the air flow.
As shown in fig. 1, in this embodiment, the air guiding member 300 has two air guiding surfaces disposed at an included angle, and the two air guiding surfaces are used for dividing the air flow and guiding the air flow to the air inlet holes 210 on the left side and the air inlet holes 210 on the right side of the fan 200 respectively.
The number of the air inlet holes 210 of the existing fan 200 may be two, and the two air inlet holes 210 are coaxial and are respectively located on the left side and the right side of the fan 200. The two flow guide surfaces are arranged in a V shape, for example, the flow guide member 300 is applied to the field of a range hood, the range hood includes a chassis 100 and a fan 200, the fan 200 and the flow guide member 300 are located inside the chassis 100, and the flow guide member 300 can be located below the fan 200. The blower 200 may be a volute blower 200, air inlet holes 210 are formed in both left and right sides of the blower 200, the blower 200 is located in the middle of the chassis 100, the guide member 300 is located right below the blower 200, and the cross section of the guide member 300 may be "V" shaped, and has two guide surfaces, which may divide and guide the airflow to the left and right sides of the blower 200. The gap 600 between the left side of the fan 200 and the left side wall 130 of the chassis 100 forms a left flow channel, the right side of the fan 200 and the right side wall 140 of the chassis 100 form a right flow channel, and the two divided air flows respectively enter the air inlet 210 on the left side of the fan 200 and the air inlet 210 on the right side along the left flow channel and the right flow channel.
The air guide 300 may be curved along an arc shape along the circumference of the air inlet hole 210.
Since the air inlet holes 210 are circular, the longitudinal section of the baffle member 300 may be curved, for example, circular or elliptical, to better correspond to the degree of curvature of the edges of the air inlet holes 210 adjacent to the baffle member 300.
Further, the bending degree of the longitudinal section of the flow guide member 300 may correspond to the bending degree of the edge of the air inlet 210, that is, the longitudinal section of the flow guide member 300 may be arc-shaped, the radius of the arc is greater than the radius of the air inlet 210, so as to completely shield the bottom of the fan 200, and the distances from each position on the flow guide surface to the edge of the air inlet 210 are equal along the direction in which the air flow flows from the flow guide member 300 to the fan 200, so that the stability of the air flow is better.
Because the air guiding member 300 is a curved arc-shaped structure, the air guiding surface is also an arc-shaped surface, and the degree of curvature is the degree of curvature of the air guiding member 300, so that the air guiding surface can be a part of a side surface of a circular truncated cone, the axis of the circular truncated cone is parallel to the axis of the air inlet holes 210, and the air guiding surface can conduct the air flow towards the middle position of the air inlet holes 210.
Example 2
As shown in fig. 5 and 6, the difference from embodiment 1 is that, along the circumferential direction of the air inlet hole 210, the air guide member 300 includes a first air guide part 510 and a second air guide part 520 which are sequentially connected at an included angle.
The baffle 300 may be located right below the fan 200, and along the circumferential direction of the air inlet hole 210, the baffle 300 includes a first baffle portion 510 and a second baffle portion 520 inclined with respect to the vertical direction, and the inclination directions of the first baffle portion 510 and the second baffle portion 520 are opposite. The first and second flow guide parts 510 and 520 may extend in a linear direction, and the cross-sectional shape of the flow guide 300 in the longitudinal direction may be "V" shaped.
When the flow guide 300 has only one flow guide surface, it may have an inclined plate-shaped structure, and when it has two flow guide surfaces, its cross-sectional shape may be "V" shaped.
The first guide portion 510 is gradually inclined downward from one end of the guide member 300 to the middle thereof, and the second guide portion 520 is gradually increased from the middle to the other end thereof, so that the bending direction of the guide member 300 is identical to the bending direction of the lower edge of the inlet hole 210.
As shown in fig. 7-9, the range hood according to the embodiment of the present invention includes a chassis 100, a fan 200, and the above-mentioned flow guide 300; the blower 200 and the guide member 300 are installed in the case 100. Because the range hood uses the flow guide 300, the range hood has the advantages of the flow guide 300.
For a general top-suction or side-suction range hood, the flow guide 300 is located right below the fan 200, and for an integrated kitchen range hood, the flow guide 300 is located above the fan 200. For convenience of description, in the embodiment, a ceiling-mounted range hood is taken as an example for description.
The air inlet hole of the fan 200 faces the left side or the right side of the range hood, the flow guide member 300 is located below the fan 200, the flow guide member 300 extends along the front-back direction of the range hood, and in the extending direction of the flow guide member 300, the flow guide member 300 is curved, and the flow guide member 300 is curved towards the right lower side.
Air inlet holes 210 are formed in both sides of the fan 200, two guide surfaces arranged at an included angle are arranged on the guide piece 300, and the two guide surfaces are used for shunting air flow and guiding the air flow to the air inlet holes 210 on the left side and the air inlet holes 210 on the right side of the fan 200 respectively; a gap 600 is formed between the air guide 300 and the fan 200.
In the above embodiment, the fan 200 has two air inlet holes 210, one is a main air inlet hole and the other is a sub air inlet hole, which are respectively located on the left side and the right side of the fan 200, and in the prior art, the two air inlet holes 210 of the fan 200 have different air inlet amounts, the air inlet amount of the main air inlet hole is larger than that of the sub air inlet hole, and the gap 600 between the diversion member 300 and the fan 200 can make the diverted air flow partially flow into the main air inlet hole side from the air flow flowing to the sub air inlet hole side under the action of pressure, so that the air flow which cannot be completely discharged from the sub air inlet hole side can flow into the main air inlet hole side through the gap 600, thereby making up the shortage of the main air inlet hole air inlet amount and achieving the purpose of adjusting the inlet air.
Both ends of the air guide 300 are respectively connected to the front plate 110 and the rear plate 120 of the cabinet 100.
The blower 200 is installed in the cabinet 100, and a narrow gap is formed between the front end and the rear end of the blower 200 and the front plate 110 and the rear plate 120 of the cabinet 100, respectively, to form a flow dead zone. Both ends of the guide member 300 are connected to the front plate 110 and the rear plate 120 of the chassis 100, respectively, so that the guide member 300 shields the bottom of the fan 200 in the front-rear direction, and guides the airflow from bottom to top to the side of the fan 200, thereby effectively preventing the airflow from entering the flow dead zone.
Because the flow guide member 300 is curved, both ends of the flow guide member are tilted toward the fan 200, a space between the flow guide member 300 and the fan 200 is relatively small, and a flow channel space is left as large as possible. However, in the prior art, the flow guiding structure is flat, the extending direction of the flow guiding member 300 is perpendicular to the axis of the air inlet 210, and when the lowest height of the flow guiding member 300 is the same as the lowest height of the flow guiding member 300, the space between the flow guiding structure and the fan 200 in the prior art is large, and the air flow enters the case 100 due to the occupation of excessive flow channel space.
The flow guide member 300 may be connected to the front plate 110 and the rear plate 120 of the chassis 100 by screws, and the flow guide member 300 is fixed to the front plate 110 of the chassis 100 and the rear plate 120 of the chassis 100, so that the front plate 110 of the chassis 100 and the rear plate 120 of the chassis 100 are prevented from generating resonance due to airflow, and the structural strength of the chassis 100 is improved.
Further, the distance between the air inlet of the chassis 100 and the center of the air inlet 210 is a first distance H, the distance between the air inlet of the chassis 100 and the position on the diversion element 300 farthest from the air inlet 210 is a second distance H, and the ratio of the second distance to the first distance is in the range of 0-H/H-0.35.
Since the flow velocity of the air is increased closer to the air inlet hole 210 of the fan 200, the flow guide 300 is provided close to the fan 200, and the impact of the flowing air on the flow guide 300 is increased. When H/H is more than or equal to 0 and less than or equal to 0.35, the diversion member 300 has a better diversion effect on the airflow, and when H/H is more than or equal to 0 and less than or equal to 0.1, the diversion effect reaches the best. At a holding time of 20m3The noise can be reduced by about 1.5dB (A) under the condition of unchanged air volume/min.
Further, a folded edge 121 bent toward one side of the front plate 110 of the chassis 100 is disposed on a lower edge of the rear plate 120 of the chassis 100, and the diversion member 300 is attached to the folded edge 121.
The flange 121 is an inherent structure generated when the cabinet 100 is manufactured, and is a structure that inevitably occurs when processing. When h ≈ 0, the lowest point of the flow guide 300 is at the same height as the bottom opening of the chassis 100, and the flow guide 300 is closely attached to the folded edge 121 of the rear plate 120 of the chassis 100, so that the flow state is further improved. Because, if the hem 121 leaves certain distance with the water conservancy diversion spare 300 on vertical, this distance can form narrow and small runner region, and the air current can worsen the air current runner to a certain extent through this narrow and small runner region, makes the air current disorder, produces the noise.
The range hood includes a smoke collecting hood located below the cabinet 100, an oil screen 430 is provided on the smoke collecting hood, and the oil smoke enters the smoke collecting hood through the oil screen 430 and then flows upward to be sucked into the fan 200.
The fume collecting hood comprises an inner cavity 410 and an outer cavity 420 which are arranged up and down and communicated, the inner cavity 410 is communicated with the lower end opening of the case 100, the sectional area of the inner cavity 410 is gradually reduced from bottom to top, the inner cavity 410 has the function of collecting oil fume, and the speed of smoke entering the case 100 can be improved.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
