The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A ceiling-mounted range hood 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 7.
It should be noted that the ceiling-mounted range hood is generally disposed right above the range hood, and the right above arrangement enables the range hood to release the generated oil smoke toward the ceiling-mounted range hood. The bottom of the top-suction type range hood is provided with a smoke inlet, a negative pressure area formed at the smoke inlet is just above a smoke stove, the negative pressure area is close to the smoke stove, the smoke generated by the smoke stove has the characteristic of rising upwards, and the top-suction type range hood above the smoke stove is just in the best scattering direction. Therefore, the smoking effect of the top-suction type range hood is incomparable with other types of range hoods.
The top-suction range hood has the outstanding problem that a user easily touches the head when using the top-suction range hood. And it still easily occupies the culinary art space because of the whole machine depth is bigger partially, influences user operation experience. 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 each other. However, the depth of the common top-suction 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 ceiling type range hood 100 through optimizing the inner structure design, pursues the smoking effect of low windage, no leaking cigarette, can reduce the complete machine degree of depth to being less than or equal to 320 mm. The cigarette machine with the reduced depth can be easily coordinated when being installed in a home. As shown in fig. 2, the kitchen installation effect diagram of the top-suction type range hood according to the embodiment of the present invention can be set with the baffle 210 at the front side of the top-suction type range hood 100, and the baffle 210 is uniform with the storage cabinet 200 beside the top-suction type range hood in appearance, so that the overall style of the kitchen is consistent.
As shown in fig. 3-5, a ceiling-mounted range hood 100 according to the present invention includes: a box shell 1 and a fan 3. An air duct 14 is arranged in the box shell 1, and a smoke inlet 11 is arranged at the bottom of the box shell 1. The fan 3 is arranged in the box shell 1, the fan 3 comprises a volute 33 and a centrifugal wind wheel 34, a front inlet 36 is arranged on the front surface of the volute 33, and a rear inlet 37 is arranged on the rear surface of the volute 33. The centrifugal wind wheel 34 is arranged in the volute 33, the rotation axis of the centrifugal wind wheel 34 is arranged along the front-back direction, and when the centrifugal wind wheel 34 rotates, air enters from the front inlet 36 and the back inlet 37 respectively.
Wherein, the size S of the ceiling-mounted range hood 100 in the front-back direction (i.e. the depth of the range hood) is less than or equal to 320mm, the distance between the front inlet 36 and the front wall of the air duct 14 is L1, the distance between the rear inlet 37 and the rear wall of the air duct 14 is L2, and the distance between L1/L2 is more than or equal to 1.7 and less than or equal to 2.3.
The embodiment of the utility model provides an in, its institutional advancement's design target is within 320mm with the degree of depth control of cigarette machine, and under people's conventional service condition, the cigarette machine can not bump the head easily like this to promote user experience.
But after the cigarette machine degree of depth diminishes, the biggest difficult problem that appears lies in, 14 spaces in wind channel diminish, and the inner wall of wind channel 14 leads to the air inlet windage grow to 3 distances of fan, arouses the not enough problem of cigarette machine oil absorption ability easily, and the windage grow simultaneously also can lead to the complete machine noise grow.
In the prior art, because the depth dimension of the top-suction range hood is large, the problem of difficult air suction caused by too close distance between the inner wall of the air duct and the air suction port of the fan does not exist, and the prior art still does not have reference experience for solving the problem.
To solve the above problems, the utility model teams try various possibilities. Such as replacing fan type, adjusting fan direction, etc. However, if the rotation axis of the centrifugal wind wheel is vertically arranged, the narrow depth of the range hood can restrict the size of the centrifugal wind wheel, and the air suction capacity of the small-sized centrifugal wind wheel cannot meet the requirement of the range hood. If the centrifugal wind wheel is replaced by the axial flow fan, the rotation axis of the axial flow fan can only be vertically arranged, the axial flow fan enters air from the lower part and exhausts air from the upper part, but the narrow depth of the range hood requires the axial flow wind wheel to be smaller in size, and the air suction capacity of the range hood is greatly weakened. If the smoking capacity is improved by simply increasing the number of fans, not only the internal structure becomes complicated, but it becomes difficult to limit the depth of the cigarette maker to within 320 mm.
After experiencing the heavy failure, the utility model people team tries to adopt the centrifugal fan as the air suction pump body, and then optimizes the setting to the structure. The calculation shows that under the condition of a small space, the centrifugal fan is arranged into double inlets, so that a certain air inlet amount can be compensated. However, it is far from enough to use only double inlets because the wind pressures of the two inlets will affect each other and have a wind-fighting relationship. In order to balance the wind pressure between the two, adjust the reasonable wind resistance, and finally adjust the optimal air intake ratio of the double suction fan, the relationship between the distance L1 between the front inlet 36 and the front wall of the air duct 14, and the distance L2 between the rear inlet 37 and the rear wall of the air duct 14 is: L1/L2 is more than or equal to 1.7 and less than or equal to 2.3.
Therefore, the obtained ceiling-mounted range hood 100 can adjust the air pressure and the air resistance of the double-suction fan by limiting the distance ratio between the front part and the rear part of the double-suction fan and the inner wall of the air channel, so as to obtain the optimal air inlet ratio and realize the oil smoke absorption effect without smoke leakage. The low-wind-resistance fan mounting mode can reduce the on-way resistance of the fan 3 on the rack and the noise of the whole machine, so that the depth of the range hood can be reduced to within 320mm, the miniaturized design of the top-suction range hood 100 is realized, a larger cooking space is convenient to obtain, and the risk of using a collision head is solved. In addition, the volume of the whole machine is reduced, and the manufacturing cost and the installation difficulty are reduced.

Wherein optionally, the rotation axis of the centrifugal wind wheel 34 is parallel to the horizontal direction, and the volute 33 blows air from the top. The centrifugal wind wheel 34 is arranged in such a way, on one hand, the size of the box shell 1 in the front-back direction is convenient to reduce, and the front-back inlet of the fan 3 is ensured to have enough space to form a negative pressure area. And the arrangement enables the wind resistance of the front inlet and the rear inlet to be easily controlled through calculation, and can simplify the design steps. The installation is convenient, and the condition that the bending moment is too large due to the deflection of the installation structure is avoided.
Further, as shown in fig. 4, the centrifugal wind wheel 34 includes: the centrifugal rotor includes a hub 341, a plurality of front blades 342, and a plurality of rear blades 343, the plurality of front blades 342 are connected to a front side of the hub 341, the plurality of front blades 342 are uniformly spaced around a rotation axis of the centrifugal rotor 34, the plurality of rear blades 343 are connected to a rear side of the hub 341, and the plurality of rear blades 343 are provided in one-to-one correspondence with the plurality of front blades 342. The mutual influence of the wind pressure areas formed by the front inlet and the rear inlet is small, the turbulence is reduced, and the sufficient wind suction amount is ensured.
Specifically, the axial dimension of the leading blade 342 is greater than the axial dimension of the trailing blade 343. Therefore, the proportional relationship between the distance L1 between the front inlet 36 and the front wall of the air duct 14 and the proportional relationship between the distance L2 between the rear inlet 37 and the rear wall of the air duct 14 can be better matched, and the total air suction capacity of the range hood is further improved.
In some embodiments, as shown in fig. 3-5, the housing 1 has a smoke collecting hood 10 at the bottom, and the smoke inlet 11 is provided on the bottom surface of the smoke collecting hood 10.
