The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
A side draft range hood 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 12.
It should be noted that, in order to make up for the problem of insufficient smoke-collecting area at the top of the side-suction range hood, the lower side inclined plane is closer to the cooking appliance, which is likely to occupy the cooking space due to the larger depth of the whole range hood and affect the operation experience of the user. And the whole machine depth (which means the size of the range hood in the front-back direction) of the range hood is larger, so that the range hood is difficult to be completely contained in the storage cabinet during household installation. As shown in fig. 1, a row of storage cabinets is installed above a cooking bench, and the storage cabinets are not usually too deep to avoid colliding with the kitchen. However, the depth of the common side-draft range hood is too large, the storage cabinet cannot be installed at the range hood, and the overall style of a kitchen is difficult to coordinate at the range hood.
And the utility model discloses side-draught range hood 100 through optimizing the runner design, pursues the oil absorption cigarette effect that does not have under the less amount of wind and reveal, can reduce the complete machine degree of depth to less than or equal to 340 m. As shown in fig. 2, the schematic diagram of the kitchen installation effect of the side-suction type range hood according to the embodiment of the present invention can set the baffle 210 at the front side of the side-suction type range hood 100, and the baffle 210 is uniform with the storage cabinet 200 beside the side in appearance, so that the overall style of the kitchen can be coordinated. The utility model discloses in some embodiments, the complete machine height less than or equal to 500mm of side-draught range hood 100, this kind of cigarette machine can not expose from baffle 210 below in installation back bottom, and whole cigarette machine can be contained completely in locker 200 even, and the kitchen aesthetic property is better. The cigarette machine is designed to be small in depth and height, so that the operation experience of a user can be prevented from being influenced.
The utility model discloses in through CFD runner calculation method, can carry out optimal design to first air-inlet grille 21, second air-inlet grille 22 and hold together cigarette board 4, the oil smoke can get into casing 1 through first fresh air inlet 211 and second fresh air inlet 221 betterly, strengthens holding together cigarette effect and improving oil absorption cigarette efficiency of range hood, and then realizes the miniaturization of cigarette machine.
The specific principle is as follows:
the oil smoke presents a diffusion type ascending state in the ascending process, the first air inlet grille 21, the second air inlet grille 22 and the smoke collecting plate 4 are arranged according to the ascending path of the oil smoke and the established appearance structure of the machine shell 1, the path of the oil smoke to the suction port 31 is simplified, the escape of the oil smoke is reduced, and therefore the efficient oil smoke extraction effect under the same air volume is achieved.
The first air-inlet grille 21 and the second air-inlet grille 22 can be allocated in area within the optimized position interval according to the optimized area interval of the rear suction opening 31, and are not limited to a specific shape.
Under the condition of the optimal inlet area of the first air-inlet grille 21 and the second air-inlet grille 22, the problem of uneven left and right suction force caused by the placing positions of the outlets 32 of the fan 3 can be solved by adjusting the area distribution of the first air-inlet grille 21 and the second air-inlet grille 22.
The offset distance between the plane of the first air-inlet grille 21 and the plane of the second air-inlet grille 22 and the plane of the suction port 31 can be adjusted along with the height change of the planes.
As shown in fig. 3 and 4, according to the utility model discloses side suction type range hood 100, including casing 1, fan 3 and holding together cigarette board 4, casing 1's side shape is approximate to the trapezoidal of invering, and casing 1's front panel 11 inclines the setting backward in the downward direction, is equipped with first air-inlet grille 21 and second air-inlet grille 22 on the front panel 11, and first air-inlet grille 21 is located the top of second air-inlet grille 22, is equipped with a plurality of first inlet openings 211 on the first air-inlet grille 21, is equipped with a plurality of second inlet openings 221 on the second air-inlet grille 22, and casing 1's top is equipped with air outlet 12.
A fan 3 is arranged in the casing 1, and the fan 3 is a centrifugal fan. A suction port 31 of the fan 3 is provided toward the front panel 11, and an outlet 32 of the fan 3 is connected to the air outlet 12.
The smoke collecting plate 4 is connected on the front panel 11, and the joint of the smoke collecting plate 4 and the machine shell 1 is positioned above the first air inlet grille 21.
The size of the side-draft range hood 100 in the front-back direction is less than or equal to 340m, the size of the side-draft range hood 100 in the up-down direction is less than or equal to 500mm, and the range of the inclination angle of the plane where the first air inlet grille 21 and the second air inlet grille 22 are located relative to the vertical plane is 20-50 degrees.
Here, the fan 3 generates a suction force at the suction port 31 after rotating, and draws the external smoke into the cabinet 1 through the first air inlet holes 211 of the first air inlet grill 21 and the second air inlet holes 221 of the second air inlet grill 22. The smoke in the machine shell 1 is compressed by the fan 3 and then discharged through the air outlet 12 on the machine shell 1. In the process of cooking food, the oil smoke is transpired upwards, and the inclined front panel 11 can increase the contact area with the oil smoke transpired upwards, so that the oil smoke can be in contact with the first air inlet grille 21 and the second air inlet grille 22 in a larger area. The first air-inlet grille 21 has a plurality of first air-inlet holes 211, the second air-inlet grille 22 has a plurality of second air-inlet holes 221, the first air-inlet grille 21 is positioned at the upper end of the second air-inlet grille 22, that is, the generated oil smoke can enter the casing 1 through two paths, wherein, the second air inlet grille 22 is close to the oil smoke source, when the generated oil smoke contacts the front panel 11, the oil smoke at the lower part of the front panel 11 is dense, the dense oil smoke enters the casing 1 along the second air inlet holes 221 first, the oil smoke outside the casing 1 continuously transpires upwards and enters the casing 1 along the first air inlet holes 211, a part of the oil smoke outside the casing 1 continuously transpires upwards, at the moment, the smoke collecting plate 4 is in an open state, the smoke collecting plate 4 can collect the oil smoke, then the oil smoke enters the machine shell 1 along the air inlet hole 21 to avoid the oil smoke escaping, thereby realizing the high-efficiency smoke extraction effect under the same air quantity.
The oil smoke can continuously rise after entering the casing 1, and the air outlet 12 is arranged at the top of the casing 1, so that the oil smoke can be dissipated upwards from the casing 1, and the smoke exhaust efficiency of the side-draft range hood 100 is improved. The first air inlet grille 21 and the second air inlet grille 22 can intercept most oil smoke particles, the service life of the range hood is guaranteed, and meanwhile, the discharged oil smoke can be reduced, and the environment is protected.
Because the depth dimension of the side-draft range hood 100 is required to be less than or equal to 340m, the height dimension is less than or equal to 500mm, and the internal space of the casing 1 is small, the centrifugal fan is used for smoking, the characteristic that the impeller 34 of the centrifugal fan is flattened compared with other impellers is utilized, the centrifugal fan has strong wind suction force, and the small body can be ensured to have enough power for smoking. The centrifugal fan has limited space for adjusting the position in the casing 1, and the suction port 31 of the fan 3 directly faces to the first air inlet grille 21, so that the external smoke is sucked towards the suction port 31 of the fan 3. The small-depth cigarette machine has the best smoking effect by matching the inclination angles of the first air-inlet grille 21 and the second air-inlet grille 22 with the cigarette collecting plate 4. The first air inlet grille 21 and the second air inlet grille 22 are used as inlets, air inlet resistance is small, an air inlet path is short, and noise is low.
In addition, the side surface of the machine shell 1 is approximately inverted trapezoid, the back surface of the machine shell 1 is almost close to being installed along the wall, the center of gravity of the whole machine body is close to the wall, the generated bending moment is small, and the installation is stable. Because the depth dimension of the casing 1 is greatly limited, the casing 1 is set to be trapezoidal, which is beneficial to ensuring the internal space capacity of the casing 1 and avoiding the smoke in the casing 1 from being buffered because the fan 3 is not drawn away in time.
Of course, the side-draft range hood 100 according to the embodiment of the present invention may be configured with a flue and a noise elimination component (not shown) as required. When the side-draft range hood 100 is configured with a flue, the flue is connected to the top of the housing 1 and is communicated with the air outlet 12, the flue is used for exhausting flue gas out of a kitchen, and the height of the flue is not limited here. The silencing component can be arranged in the machine shell 1, and the silencing components can be arranged in the machine shell 1 and the flue.
According to the utility model discloses side suction type range hood 100, the inclination of given casing 1 appearance, first air-inlet grille 21 and second air-inlet grille 22 with hold together 4 designs of cigarette board, designs out the best route that the oil smoke rises, can reduce the loss of local vortex, noise abatement promotes complete machine work efficiency, reaches the less smoke leakage even zero smoke leakage effect under the same amount of wind. By effectively shortening the depth of the whole machine to within 340m and shortening the height to within 500mm, the appearance of the whole machine structure is neat and simple, some of the whole machine structure can be even hidden in the storage cabinet 200, the miniaturization of the side-suction type range hood 100 is realized, and the larger cooking space is convenient to obtain. In addition, the volume of the whole machine is reduced, and the manufacturing cost and the installation difficulty are reduced.
Optionally, the first air inlet grille 21 is detachably connected to the housing 1, so that the first air inlet grille 21 can be quickly disassembled and assembled, and the fan 3 can be conveniently disassembled and assembled. For example, the first air grille 21 may be snap-fitted to the front panel 11; the first air inlet grille 21 can be hinged to the casing 1 at one end and connected to the casing 1 by a latch or a buckle at the other end. Of course, the connection manner of the first air grille 21 of the embodiment of the present invention is not limited to this, for example, the first air grille 21 may be fixedly connected to the front panel 11, and even the first air grille 2 is integrally formed on the front panel 11, and the front panel 11 is an openable structure on the casing 1.
Optionally, the second air inlet grille 22 is detachably connected to the housing 1, so that the second air inlet grille 22 can be quickly disassembled and assembled, and the fan 3 can be easily disassembled and assembled. For example, the second grille shutter 22 may be snap-fitted to the front panel 11; the second air inlet grille 22 may be hinged to the casing 1 at one end and connected to the casing 1 by a latch or a snap at the other end.
Specifically, as shown in fig. 3 and 4, the fan 3 includes: the volute 33 is arranged in the machine shell 1, the volute 33 is provided with a suction opening 31, and the suction opening 31 is arranged on the front side of the volute 33 and faces the first air inlet grille 21. The air outlet duct 36 is connected to the volute 33, and the upper end of the air outlet duct 36 forms the outlet 32 and is connected to the air outlet 12 of the casing 1. The impeller 34 is provided in the scroll casing 33, and the motor 35 is mounted on the rear portion of the scroll casing 33.
In some embodiments of the present invention, as shown in fig. 4, the inclination angle of the surface of the impeller 34 of the fan 3 with respect to the vertical surface is in a range of 0 degree to 25 degrees, and the surface of the impeller 34 is perpendicular to the rotation axis of the fan 3. That is, the surface of the impeller 34 may be vertically disposed or may be inclined like the front panel 11 of the casing 1. However, in order to generate the upward and rearward suction force and also to ensure that the depth of the whole machine is shortened to within 340m, the inclination angle of the surface on which the impeller 34 of the fan 3 is located with respect to the vertical surface is preferably in the range of 0 to 25 degrees.
In the example of fig. 4, when the impeller 34 is inclined relative to the vertical plane, the volute 33 also needs to be inclined, and the air outlet duct 36 is arranged vertically, so as to ensure the shortest smoke outlet path.
In some examples, as shown in fig. 4, the suction port 31 is formed at an angle with respect to the front panel 11 of the casing 1, and the distance therebetween is gradually decreased in the downward direction. Thus, in the gap between the suction port 31 and the front panel 11, the upper space has a large capacity, and the smoke is more easily sucked upward. In other words, because the flue gas itself characteristic is exactly to rise upwards after producing, the flue gas gets into casing 1 from air inlet 21 after, and enough space holds the flue gas when rising upwards, if the flue gas is not in time taken out by fan 3, the flue gas also can not follow air inlet 21 and escape, improves smoking efficiency, avoids running the cigarette.
In some embodiments of the present invention, as shown in fig. 4-7, the suction port 31 of the fan 3 has a highest point P and a lowest point Q, and in the up-down direction, the upper edge M of the first air grille 21 is located between the highest point P and the lowest point Q, and the lower edge N of the first air grille 21 is located below the lowest point Q.
Here, because the smoke itself has the characteristic of rising upwards, if a large amount of sucked smoke rises to exceed the highest point P, the smoke is sucked downwards, and a very large suction force and air volume are required to suck the smoke towards the suction port 31, so that energy waste is caused. Therefore, the upper edge M of the first air grille 21 is set not to exceed the highest point P of the suction port 31, and the smoking efficiency can be improved. And because the air inlet from the upper edge M to the highest point P is blocked by the front panel 11, the fan 3 can form stronger negative pressure at the part of the front panel 11 above the upper edge M, and the smoking effect is greatly enhanced.
The lower edge N of the first air-inlet grille 21 is arranged below the lowest point Q, so that the air inlet area can be greatly increased. Wherein, because the inside of casing 1 encircles suction inlet 31 and can form the negative pressure region, although the lower limb N of air-inlet grille 2 is less than minimum Q, does not influence fan 3 and follow regional quick smoking in below, avoids the phenomenon of falling the cigarette.
Specifically, as shown in FIG. 4, the upper edge S of the second grille shutter 22 is located below the lowest point Q, and the lower edge T of the second grille shutter 22 is located behind the lowest point Q. That is to say, second air inlet grille 22 is located the lower extreme of fan 3, because second air inlet grille 22 is not directly relative with suction inlet 31, can possess certain buffering behind the oil smoke entering casing 1, avoids the flue gas in casing 1 to have no buffering because of fan 3 does not in time take out.
Further, the first air grille 21 is located in front of the lowest point Q of the suction port 31, and the second air grille 22 is located behind the lowest point Q of the suction port 31. The first air-intake grille 21, which is located at the front side of the suction port 31, sucks the flue gas with just the maximum air volume. And the negative pressure at the suction port 31 can be expanded to the second air-inlet grille 22 by utilizing the second air-inlet grille 22 positioned at the rear side of the suction port 31, so that the air-inlet area is increased. After a large amount of smoke is sucked in the large-area negative pressure area, the smoke suction quantity at the first air inlet grille 21 is increased, and the area below the fan 3 in the casing 1 can also be used for caching the smoke, so that the smoke gathering effect is enhanced, and the zero-smoke-leakage effect under the same air quantity is realized.
The second air-inlet grille 22 is utilized to increase the negative pressure area in front of the front panel 11 by dividing the upper stylized grille of the front panel 11 into two parts and separating the two air-inlet grilles.
In some embodiments of the present invention, in the extending direction of the front panel 11, the distance range between the lower edge T of the second air grille 22 and the bottom edge L of the casing 1 is 50mm to 250mm, and the distance range between the lower edge N of the first air grille 21 and the bottom edge L of the casing 1 is 100mm to 300 mm. Wherein, the distance between the lower limb T of second air inlet grille 22 and the bottom edge L of casing 1 can reach 50mm in the shortest, and the distance between the lower limb N of first air inlet grille 21 and the bottom edge L of casing 1 can reach 100mm in the shortest, that is to say the utility model discloses on the cigarette machine structure basis, can enlarge the air inlet area as far as possible, still do not influence the smoking effect.
In some embodiments of the present invention, the surface of the first air grille 21 or the second air grille 22 is a plane, a curved surface or a combined surface. The combination surface can be a combination of different planes, a combination of different curved surfaces, or a combination of a plane and a curved surface. The first air-inlet grille 21 or the second air-inlet grille 22 may be projected on the front panel 11 in a square shape or a circular and oblong shape, and the first air-inlet grille 21 or the second air-inlet grille 22 may also be projected on the front panel 11 in an irregular shape.
In some embodiments of the present invention, the plurality of first air inlet holes 211 are arranged in a plurality of rows and columns, and each first air inlet hole 211 is a long strip extending in the transverse direction. The oil smoke can enter the cabinet 1 through the first air inlet holes 211, and at this time, the first air inlet holes 211 can absorb the oil smoke which is transpired upwards along the front panel 11 and the oil smoke which is collected by the smoke collecting plate 4. The first air inlet holes 211 extending transversely are beneficial to guiding the flue gas in the horizontal direction better, and increase the air suction area. And the smoke absorption amount of the first air-inlet grille 21 is not reduced under the suction force of the second air-inlet grille 22 and the smoke collecting effect of the smoke collecting plate 4.
Alternatively, as shown in fig. 9 and 10, the length a1 of the first air inlet holes 211 ranges from 5mm to 80mm, the width b1 of the first air inlet holes 211 ranges from 1mm to 20mm, and the spacing distance c1 of the first air inlet holes 211 ranges from 10mm to 50 mm. The length a1 of the first air inlet holes 211 can be 5mm at the minimum, the width b1 can be 1mm at the minimum, and the spacing distance c1 can be 10mm at the minimum, so that the first air inlet holes 211 are small in size and dense in arrangement, and the oil smoke can be filtered conveniently.
In some embodiments of the present invention, as shown in fig. 4, the second air inlet holes 221 are spaced apart from each other in the horizontal direction, and each second air inlet hole 221 is a long strip extending in the vertical direction. Therefore, the transpiration direction of the oil smoke is basically consistent with the opening direction of the second air inlet holes 221, and the oil smoke can more easily enter the machine shell 1 through the second air inlet grille 22. Optionally, the second air inlet hole 221 is formed by one or more sections, each section being a straight section or a curved section, so as to satisfy various appearance requirements.
Alternatively, as shown in fig. 7 and 8, the length a2 of the second air inlet openings 221 ranges from 20mm to 150mm, the width b2 of the second air inlet openings 221 ranges from 4mm to 20mm, and the spacing distance c2 of the second air inlet openings 221 ranges from 4mm to 20 mm. The length a2 of the second air inlet hole 221 may be 20mm at the minimum, the width b2 may be 4mm at the minimum, and the spacing distance c2 may be 4mm at the minimum, so that the size of the second air inlet hole 221 is large, which is beneficial for dense oil smoke to enter the enclosure 1, and the second air inlet grille 22 is not arranged too densely and too sparsely, which is beneficial for reducing air inlet resistance, and simultaneously, it is ensured that the fan 3 has enough air inlet suction force at the second air inlet hole 221.
Of course, it can be understood that when the overall depth of the side-draft range hood 100 is changed between different ranges, the size ranges of the first air inlet holes 211 and the second air inlet holes 221 can be correspondingly increased or decreased, and are not limited to a fixed range.
The utility model discloses an in some embodiments, hold together cigarette board 4 angularly adjustable ground and connect on front panel 11, and under the shutdown state, hold together cigarette board 4 coincide on air-inlet grille 2. That is to say, the smoke collecting plate 4 can be rotated to open and collect the oil smoke, so as to reduce the dissipation of the oil smoke and improve the absorption of the oil smoke. Under the shutdown state, hold together cigarette board 4 coincide on first air-inlet grille 21, furtherly, hold together and can laminate completely with front panel 11 after cigarette board 4 coincide, realize that front panel 11 levels pleasing to the eye, can also avoid the granule pollutant in the air to pile up on air-inlet grille 2, the influence is discharged fume.
In some examples of the present invention, the adjustment of the cigarette holding plate angle 41 can be realized by a limiting structure or a connecting rod structure, which is simple and effective, and certainly can be realized by other methods without limitation. Because the oil smoke volume that adopts the culinary art means of difference to produce is different, hold together the angle of cigarette board 4 and can adjust according to the culinary art situation of difference, for example, hold together cigarette board 4 and can have three angle, can adjust first angle with holding together cigarette board 4 when boiling water, will hold together cigarette board 4 when cooking and adjust the second angle, will hold together cigarette board 4 and adjust the third angle when stewing the dish for side-suction type range hood 100 all has better and holds together the cigarette effect under the culinary art situation of difference.
