Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
Example one
Referring to fig. 1 to 3, a side-draft range hood includes a housing 1 and a panel 2 obliquely disposed on a front side of the housing 1. For convenience of description, in this specification, "front", "rear", "left", "right", "up" and "down" refer to the direction of the extractor hood relative to the user.
The housing 1 includes a back plate 11 at the rear side and a top plate 12 at the top, and in this embodiment, the back plate 11 may be integrally formed with the top plate 12. The panel 2 is provided with an air inlet 21, the smoke baffle 3 matched with the air inlet 21 in size is rotatably arranged on the panel 2, and the air inlet 21 can be opened or closed through rotating relative to the panel 2.
A fan 4 is arranged in the housing 1, and the fan 4 includes a volute 41, an impeller 42 arranged in the volute 41, and a motor 43 for driving the impeller 42 to rotate. The rear bottom of the scroll 41 abuts the back plate 11. The fan 4 is arranged obliquely, as is preferred, in line with the inclination of the panel 2. The motor 43 is installed at the rear of the scroll casing 41 and partially penetrates into the scroll casing 41 so that an output shaft of the motor 43 can be connected with the impeller 42 to drive the impeller 42 to rotate.
An oil guide plate 5 is arranged between the volute 41 and the panel 2, and the oil guide plate 5 comprises a main plate 51 and an opening 52 which is opened on the main plate 51 and is preferably in the middle. The left and right sides of the main plate 51 are provided with bending parts 53 bent forward, and the bending parts 53 are used for arranging the oil guide plate 5The body is mounted to the rear side of the panel 2. The bent portion 53 is required to be closely attached to the rear side of the panel 2 in order to prevent the leakage of the soot introduced from the air inlet 21. The bending portion 53 is provided with a first guiding hole 531. The total area of each first flow guide hole 531 is D, and the value of D is too small to play a role in gas flow guide; the value D is too large, which affects the normal use of the range hood, such as the reduction of the oil smoke absorbing capacity, the insufficient rigidity of the oil guide plate 5, and the like, so that the value range of D is preferably as follows: 100mm2<D<9000mm2. In this embodiment, the first guiding holes 531 are formed in the bent portions 53 on both sides, and each of the first guiding holes 531 is a rectangular hole with a height of 24mm and a length of 100 mm.
An air inlet ring 6 is arranged at the opening 52 of the oil guide plate 5, and the air inlet ring 6 corresponds to the air inlet 21 on the panel 2. The oil guide plate 5 separates the space in the housing 1, so that the airflow at the rear side of the oil guide plate 5 can only pass through the first flow guide hole 531 and enter the front side of the oil guide plate 5, and then enter the fan 4 from the air inlet ring 6.
Referring to fig. 2 to 10, the fan 4 is arranged obliquely, e.g. preferably in line with the inclination of the panel 2. The volute 41 includes a front cover plate 411 and a rear cover plate 412, and the rear cover plate 412 may be connected and fixed with the back plate 11 by a bracket. An annular wall may be provided between the front cover plate 411 and the rear cover plate 412, or the annular wall may not be provided, or the front cover plate 411 and the rear cover plate 412 are bent toward each other to form the annular wall.

The rear cover 412 is provided with a mounting hole 4122 through which the motor 43 passes.
The motor 43 includes a motor body 431, a motor rear cover 432, a motor front cover 433, and a skirt 434. The motor rear cover 432 and the motor front cover 433 are arranged in the axial direction in front and rear, and the motor main body 431 is located inside the motor rear cover 432 and the motor front cover 433. A skirt 434 may be provided at the outer periphery of the whole of the motor rear end cover 432 and the motor front end cover 433, and it is in a radially outwardly protruding ring shape, and the skirt 434 is adapted to be mounted with the rear cover plate 412 of the scroll casing 41. Bolts can be passed through the periphery of the mounting holes 4122 of the back cover plate 412 to screw-lock the skirt 434. The motor 43 is mounted to the impeller 42 through a back cover plate 412 of the volute 41. Skirt 434 of motor 43 is located at the front side of rear cover plate 412 of volute 41 (inside volute 41).
The impeller 42 includes a front ring 421, a rear ring 422, and a vane 423 disposed between the front ring 421 and the rear ring 422. The impeller 42 further includes a disk 424 for fixing the motor 43, the disk 424 is located inside the impeller 42, and preferably, is located in the middle of the impeller 42 in the radial direction, and the disk 424 is fixedly connected to the rear ring 422. The output shaft 435 of the motor 43 is fixed to the disk 424 through the disk 424, and thereby the impeller 42 is integrally rotated by the disk 424.
A tightening nut 44 is provided on the front side of the disk 424, on a portion of the motor 43 after the output shaft 435 passes through the disk 424, for tightening and locking the output shaft 435 with the disk 424. The fastening nut 44 is configured as an axial fan, and is provided coaxially with the central axis of the impeller 42 and the output shaft 435 of the motor 43. When the tightening nut 44 rotates with the output shaft 435 of the motor 43, the flow direction of the gas is parallel to the central axis of the impeller 42. The edges of the tightening nut 44 are designed in a regular hexagonal pattern to facilitate the removal of the tightening nut 44.
In order to send the air flow blown by the tightening nut 44 to the vicinity of the motor 43, the disk 424 is provided with a vent hole 4241 surrounding the outer periphery of the output shaft 435 of the motor 43 and corresponding to the tightening nut 44. The sum of the areas of all the vent holes 4241 is a, and if the value of a is too small, the airflow cannot be efficiently sent to the vicinity of the motor 43; if the value of a is too large, the impeller 42 becomes less rigid and the effective air flow around the motor 43 becomes small. In summary, the optimal value range of a is: 30mm2<A<0.12 × 3.14 × d, d is the diameter of the disk 424 of the impeller 42. In the present embodiment, twelve circular holes of 6mm in diameter are uniformly punched in the vent holes 4241 around the output shaft 435 of the motor 43 as the vent holes 4241.
In order to send the air flow from the impeller 42 to the periphery of the portion of the motor 43 located outside the volute casing 41, there is a mounting gap between the motor 43 and the back cover plate 412 of the volute casing 41 through which the air flow passes, a gap (distance between surfaces close to each other) between the skirt 43 and the back cover plate 412 of the volute casing 41 (which are parallel to each other) in the axial direction of the motor 43 is H1, and a gap (distance between surfaces close to each other) between the back end cover 432 of the motor 43 and the inner periphery of the mounting hole 4122 of the back cover plate 412 of the volute casing 41 in the radial direction of the motor 43 is H2. If the values of H1 and H2 are too small, the flow of gas in the gap is influenced, and if the values are too large, the normal use of the range hood is influenced, for example, the range hood has poor oil fume suction effect, the shaking of the whole range hood is intensified, the noise is increased, and the like. Thus, preferably, 2.5mm < H1<9mm, 2mm < H2<7 mm. Thus, the airflow entering the rear side of the disk 424 can enter the rear side of the volute 41 and around the motor 43 through the above-described mounting gap between the motor rear cover 432 and the inner periphery of the mounting hole 4122 of the volute, and the mounting gap between the skirt 434 and the rear cover plate 412 of the volute 41.
When the range hood normally works, the motor 43 drives the impeller 42 and the screwing nut 44 to rotate, the screwing nut 44 blows partial or trace air flow to the wheel disc 424, the air flow passes through the vent hole 4241 on the wheel disc 424, blows the front end cover 431 of the motor 43, then flows through the gap between the motor 43 and the rear cover plate 412 of the volute 41, then blows the rear end cover 432 of the motor 43, flows through the inside of the housing 1, and finally enters the volute 41 again through the first flow guide hole 531 formed in the bending part 53 of the oil guide plate 5 to be discharged to the outside. Such airflow kinetic energy accelerates the flow of the air around the front end cover 431 and the rear end cover 432 of the motor 43, enhances the heat dissipation performance of the motor 43, and reduces the temperature rise of the motor 43. Experiments prove that by adopting the scheme of the embodiment, the temperature rise of the motor 43 can be reduced by about 3K to 10K, the temperature rise of the motor 43 is greatly reduced, the performance of the motor 43 is improved, and the service life of the motor 43 is prolonged.
Example two
Referring to fig. 11 and 12, in the present embodiment, the difference from the first embodiment is that the second diversion hole 4123 is formed in the back cover plate 412 of the scroll casing 41, and there is no need to form a diversion hole in the oil guide plate 5 or leave a gap between the motor 43 and the back cover plate 412 of the scroll casing 41. The second flow guiding holes 4123 are arranged around the motor 43, the sum of the areas of all the second flow guiding holes 4123 is B, the value of B is too small, the airflow passing through the rear cover plate 412 of the volute 41 is too small to play a role of accelerating the gas flow of the rear end cover 432 of the motor, the value of B is too large, and the range hood can generate abnormal sound when in normal operationThe rigidity of the volute 41 is also reduced. Therefore, the preferable value range of B is as follows: 10mm2<B<300mm2. In the present embodiment, 8 circular second guide holes 4123 with a diameter of 6mm are uniformly arranged on the rear cover plate 412 of the scroll casing 41.
The minute amount of the air flow entering the rear side of the scroll 41 flows out from the back plate 11 of the housing 1. The back plate 11 is provided with a hook hole 111 for mounting on a wall, and most of the air flow is discharged from the hook hole 111. The rear side of backplate 11 still is provided with pad foot 112, and pad foot 112 height is H, and H is too little, and range hood is pasting the wall, influences gas flow, and H is too big, and range hood shake aggravation during normal work, consequently, preferred, the scope of H should be: 2mm<H<25 mm. In addition, if the hook hole 111 is too small, the range hood is not well hung, the airflow cannot come out from the hook hole 111, and if the hook hole 111 is too large, the rigidity of the integral back plate 111 and the vibration of the housing 1 during the operation of the range hood are affected. In summary, after the range hood is hung on the hook, the area of the remaining hook hole 111 is C, and the value range of C is: 25mm2<C<600mm2。
When the range hood normally works, the motor 43 drives the impeller 42 and the screwing nut 44 to rotate, the screwing nut 44 blows partial or trace air flow to the wheel disc 424, the air flow passes through the vent hole 4241 on the wheel disc 424, blows the front end cover 431 of the motor 43, then flows through the second flow guide hole 4123 on the rear cover plate 412 of the volute 41, then blows the rear end cover 432 of the motor 43, flows through the inside of the housing 1, and finally is discharged to the outside through the hook hole 111 on the back plate 11. Such airflow kinetic energy accelerates the flow of the air around the front end cover 431 and the rear end cover 432 of the motor 43, enhances the heat dissipation performance of the motor 43, and reduces the temperature rise of the motor 43. Experiments prove that by adopting the scheme of the embodiment, the temperature rise of the motor 43 can be reduced by about 3K to 6K, the temperature rise of the motor 43 is greatly reduced, the performance of the motor 43 is improved, and the service life of the motor 43 is prolonged.
Of course, alternatively, in the present embodiment, after the airflow flows out from the scroll 41, the airflow may also enter the scroll 41 again from the oil guide plate 5 and be discharged to the outside as shown in the first embodiment. After the airflow in the first embodiment flows out from the volute 41, the airflow may be discharged to the outside from the back plate 11 as shown in this embodiment.
That is, the mounting gap between the rear cover plate 412 of the volute 41 of the fan 4 and the motor 43, or the second flow guide hole 4123 of the rear cover plate 412 of the volute 41 of the fan 4, forms a first air flow passage on the fan 4, the first flow guide hole 531 of the oil guide plate 5, or the hook hole 111 of the back plate 11, forms a second air flow passage, and the first air flow passage and the second air flow passage together form an air flow passage, so that the air flow in the impeller 42 can take away heat around the motor 43 in the process of passing through the first air flow passage and is discharged to the outside through the second air flow passage.
