Detailed Description
The technical solution of the present invention is further illustrated by the following examples.
Example 1.
A range hood with an oil smoke separation assembly is provided with a range hood main body and an oil smoke separation assembly 1 as shown in figures 1 to 4, wherein the oil smoke separation assembly 1 is assembled inside the range hood main body.
Oil smoke separating assembly 1 is provided with many concentric tubes 11 of axis coincidence, connecting portion 12, a plurality of eaves portion structure 13 and vortex generating device group 14, and the one end of connecting portion 12 respectively with many concentric tubes 11's one end fixed connection, a plurality of eaves portion structure 13 respectively with the 11 other end fixed connection of corresponding concentric tubes, and the other end of connecting portion 12 assembles in the inside of cigarette machine main part, and vortex generating device group 14 fixed mounting is in concentric tubes 11's surface.
In the present embodiment, the other end of the connecting portion 12 is preferably rotatably mounted inside the cigarette maker main body, or the other end of the connecting portion 12 may be fixedly mounted inside the cigarette maker main body.
It should be noted that the oil smoke separating assembly 1 of the present invention can be fixedly assembled inside the main body of the range hood, and when the oil smoke separating assembly 1 is fixedly assembled, the oil smoke separating assembly 1 can also play a role of separating oil smoke. When the oil smoke separation component 1 is rotatably assembled in the smoke machine main body, the centrifugal force generated by the rotation state of the smoke separation device can centrifugally separate oil smoke particles, so that the oil smoke particles can be better removed.
The cigarette machine main part is provided with rotating electrical machines 4, and connecting portion 12 is connected with rotating electrical machines 4 transmission. The rotating motor 4 is fixedly arranged in the smoke machine main body and is positioned right above the center of the oil smoke separation assembly 1, and the diameter of the rotating motor 4 is smaller than that of the oil smoke separation assembly 1. The diameter of the rotating motor 4 is smaller than that of the oil smoke separation component 1, so that oil smoke gas can smoothly enter the air draft component 5 of the cigarette machine main body.
The side of the oil smoke separation component 1 facing the ground when being installed is defined as the lower part, and the concentric tubes 11 from the middle axis to the outside are sequentially defined as the 1 st concentric tube, the (n), (b), (c), (d), (n-1) concentric tube and the n concentric tube, wherein i is more than or equal to 2 and less than or equal to n, and n is a positive integer.
Height of the 1 st concentric tube is H 1 The height of the ith concentric tube is H i The height of the n-1 concentric tube is H n-1 The height of the n-th concentric tube is H n ，H 1 Has the maximum value of H n The value of (c) is minimal. 1.1H n ≤H i ≤10H n And 0.5H i-1 ≤H i ≤3H i-1 。
The vortex generating device group 14 is fixedly installed on the outer surface of the concentric tube 11 and surrounds the joint of the cornice structure 13 and the concentric tube 11, and the vortex generating device group 14 is installed on the upper surface of the cornice structure 13.
Each group 14 of vortex generating devices consists of one or more vortex generating sub-devices of the same eaves structure 13
The number of the vortex generating device groups 14 is m, m is any positive integer larger than 0, and the m vortex generating device groups 14 are respectively and fixedly installed on the outer surface of the concentric pipe 11 and surround the joint of the eaves structure 13 and the concentric pipe 11.
N =3 in the present embodiment, that is, the concentric tubes 11 in the present embodiment are provided with 3. In this embodiment, m =2, that is, the vortex generating device group 14 is provided in 2, one is provided in the 3 rd concentric tube, and the other is provided in the 2 nd concentric tube. The number of concentric tubes 11 of the present invention can be any positive integer, and the set of vortex generating devices 14 can be less than or equal to any positive integer number of concentric tubes 11.
The concentric tubes 11 are provided with flow perturbation means 111, the flow perturbation means 111 being connected seamlessly around the end of one end of the concentric tubes 11. The flow disturbance device 111 functions to generate a vortex flow of the soot gas, thereby improving the oil removing capability.
The concentric tube 11 is formed by a line segment formed by a plurality of broken lines surrounding the middle axis for a circle, and the intersection position of two adjacent line segments on the inner wall of the concentric tube 11 is a vortex generation position 16, as shown in fig. 7. The shape of the concentric tube 11 of the invention has the function of enabling the oil smoke gas to generate vortex on the inner wall of the concentric tube 11 and improving the efficiency of removing the oil smoke.
The diameter of one end of the concentric tube 11 is larger than the diameter of the other end. One end of the concentric tube 11 is the end connected with the air draft assembly 5, namely the air outlet of the concentric tube 11, the other end of the concentric tube 11 is the air inlet of the concentric tube 11, and according to the venturi effect, the larger the area through which the fluid flows, the smaller the flow velocity is, namely, the velocity of one end of the gas concentric tube 11 is greater than the velocity of the other end of the concentric tube 11. According to bernoulli's law, the higher the speed of the gas, the lower the pressure, so the pressure at the end of the concentric pipe 11 connected with the ventilation assembly 5 is high, and the pressure at the air inlet of the concentric pipe 11 is low, thereby increasing the pressure difference between the air inlet of the concentric pipe 11 and the external environment, promoting the oil smoke gas to enter, and improving the oil absorption effect.
The eave structure 13 is provided with a plurality of through holes 131. The through holes 131 are used for gathering large oil particles when the oil fume separation component 1 rotates, and the oil fume particles are separated from the inside of the oil fume separation component 1, so that the separation effect of the oil fume particles is greatly improved.
The other end of the concentric tube 11 of the present invention may be fixedly connected with at least one eave structure 13, or the other end of the concentric tube 11 may be fixedly connected with only one eave structure 13. The other end of the 1 st concentric tube of this embodiment connects two eave structures 13. Two eaves portion structures 13 effects of 1 st concentric union coupling have reduced the space volume between 1 st concentric pipe and the 2 nd concentric pipe to reduce the area of the air inlet of the 2 nd concentric pipe, improved gaseous admission speed, increase the pressure differential of 11 inside and exterior spaces of concentric pipe.
The cigarette machine main part is provided with shell 2, convulsions subassembly 5 and oil collecting device 3, and oil smoke separator assembly 1 assembles in the inside of shell 2, and oil collecting device 3 assembles in the bottom of shell 2, and convulsions subassembly 5 fixed mounting just is located oil smoke separator assembly 1's top in the inside of shell 2.
The housing 2 is provided with a plurality of housing air inlets 21 and a plurality of annular sheets 22 matching with the housing air inlets 21, the annular sheets 22 are integrally connected with the corresponding inner surface of the housing 2 and are positioned at the edge of the housing air inlets 21, the annular sheets 22 are in one-to-one correspondence with the housing air inlets 21, the annular sheets 22 of the present invention can also be fixedly installed on the housing, and the specific implementation is determined by implementation.
The ring-shaped piece 22 functions to generate a vortex when the oil smoke gas enters the housing 2, and simultaneously prevents oil smoke particles from being thrown out of the external space from the housing air inlet 21 of the housing 2 when being thrown out of the oil smoke separation assembly 1.
The surface area of the housing 2 is S Outer casing 2 The total area of the housing inlet 21 is S Housing air inlet 21 ，0.1S Outer casing 2 ≤S Housing air inlet 21 ≤0.5S Outer casing 2 。
The ratio of the total area of the shell air inlet 21 to the surface area of the shell 2 is not more than 0.5, so that the speed of oil smoke gas entering the range hood is reduced, and the pressure difference between the inside of the range hood and the external environment is reduced. The ratio of the total area of the housing inlet 21 to the surface area of the housing 2 is not less than 0.1, because too small a housing inlet 21 will reduce the effect of absorbing the soot gas.
The air draft assembly 5 is provided with a fan, a wind wheel and a volute, the fan is assembled inside the volute, the wind wheel is in transmission connection with the fan, the volute is fixedly installed inside the cigarette machine main body, an air inlet of the volute is communicated with an air outlet above the concentric tube 11, and an air outlet of the volute is communicated with an air outlet of the cigarette machine main body.
The operating principle of the range hood of the embodiment is as follows: the range hood is opened, the rotating motor 4 drives the oil smoke separation assembly 1, the wind wheel of the air draft assembly 5 rotates simultaneously, oil smoke particles are separated in seven layers in the range hood, and finally the oil smoke particles are discharged from an almost clean gas through the gas outlet, as shown in fig. 6. The seven-layer separation is specifically as follows:
first layer separation, inertial separation: lampblack enters the interior of the range hood through the shell air inlet 21 of the shell 2, and enters the annular sheet 22 after entering the shell air inlet 21, because of the pressure difference between the interior of the shell 2 and the external environment and the sudden change of the area of the shell air inlet 21, the air flow speed is accelerated, and the inertia momentum is relatively increased. And the oil smoke will form a very thin boundary layer around the ring-shaped sheet 22, and because the outer shell air inlet 21 of the outer shell 2 forms an included angle with the ring-shaped sheet 22, the oil smoke is forced to flow upwards to enter the oil smoke separation assembly 1 after flowing downwards along the ring-shaped sheet 22, so that the heavier oil separates from the crude oil smoke flow field in the downward inertial motion and moves downwards to be collected in the oil collection device 3 at the bottom of the outer shell 2, and the first inertial separation is realized.
Second layer separation, vortex separation: the oil smoke particles separated by the first layer further generate flow field separation in the downward and upward flowing direction of the annular sheet 22, and the oil smoke particles cause an unstable flow field under the flow field separation to further form a vortex. The flow field or the vortex flow and the adjacent flow field or the vortex flow are mutually influenced mutually, a continuously rotating flow field is formed on the annular sheet 22, and the rotating vortex flow reaches the maximum vortex quantity. The remaining light oil smoke will not stop at the rotating vortex accumulation of the ring-shaped sheet 22, and when a certain weight is accumulated, the flow field will not support the weight of the oil drop, and will fall downwards or flow along the ring-shaped sheet 22 to the oil collecting device 3.
Third layer separation, centrifugal separation: the rotation of the eave structure 13 following the concentric tubes 11 creates a centrifugal force that interacts with the attractive force of the wind wheel. After the second separation, the light oil smoke of remaining part contacts the outermost end of eaves portion structure 13 earlier and gets into concentric tube 11 again when getting into concentric tube 11, and the centrifugal force of eaves portion structure 13 outermost end can leave some fluid or oil smoke particle area or block and get into concentric tube 11 inside and move outward, throws away with higher tangential velocity again, and the particle of throwing away can fall at cyclic annular piece 22, flows to oil collecting device 3 along cyclic annular piece 22 at last.
Fourth layer separation, inertial separation and centrifugal separation: after the third layer of separation, the remaining oil smoke with lighter weight is simultaneously subjected to centrifugal force and attractive force, but the relative attractive force is greater than the centrifugal force. Some of the oil smoke will flow to the adjacent eaves structure 13 through the through holes 131, and will be gathered with other oil smoke or oil smoke particles into larger oil smoke particles to flow downward due to the inertia effect, and the oil smoke particles will be thrown out at a higher tangential speed due to the centrifugal force effect and finally flow to the oil collecting device 3 along the ring-shaped pieces 22.
Fifth layer separation, cyclonic centrifugal force and secondary vortex generation of concentric tubes 11: the inner wall of the concentric tube 11 rotates to form a cyclone, the concentric tube 11 is a low-pressure area, fluid or particles in the tube move towards the wall of the tube under the action of centrifugal force, the tube wall forms a high tangential velocity, and part of oil smoke is blocked from flowing upwards. In addition, the residual oil smoke can form vortex in the vortex generating device, and the vortex generating device does not stop rotating, so that the oil smoke is captured and cannot escape from the pipeline. When the attraction force and the centrifugal force are removed, the continuously rotating secondary vortex and the oil smoke which moves at the pipe wall in a high tangent line flow downwards along the inner pipe wall to be collected in the oil collecting device 3 due to gravity.
The sixth layer is separated, and the spoiler 111 is separated: the flow disturbing device 111 at one end of the concentric tube 11 generates flow field separation on the remaining oil smoke, and the flow field separation can block part of the oil smoke from flowing upwards and capturing the oil smoke by the vortex which does not rotate automatically due to the instability of the flow field.
Separating a seventh layer, and separating a wind wheel by centrifugal force: after the first six layers of separation, a small amount of very light oil smoke particles are left to be sucked into the wind wheel of the air draft assembly 5 due to pressure difference, the rotating wind wheel forms centrifugal force to throw the remaining small amount of oil smoke particles onto the inner wall of the fan, and finally nearly clean gas is discharged outside through the air outlet.
The oil smoke separation component 1 of the range hood can enable gas to generate vortex to remove oil smoke particles in the range hood, can avoid the contact of the gas containing a large amount of oil smoke particles and the wind wheel, improves the separation effect of the oil smoke particles and avoids noise generated by oil stain accumulated by the wind wheel.
Example 2.
A lampblack absorber with a lampblack separation component is shown in figure 5, other characteristics are the same as those of embodiment 1, and the difference is that: the oil smoke separation component is provided with a metal sheet 15 which is assembled on the surface of the vortex generating device group 14. The metal sheet 15 functions to separate oil smoke by condensing the oil smoke having a relatively high temperature when the oil smoke passes through the metal sheet 15 made of a metal material due to a low surface temperature of the metal sheet 15.
In this embodiment, the soot gas is more easily separated in the vortex generating device group 14 than in embodiment 1.
Example 3.
The utility model provides a take lampblack absorber of oil smoke separating element, other characteristics are the same with embodiment 1, the difference lies in: n =4 in the present embodiment, i.e., 4 concentric tubes 11 in the present embodiment are provided. In this embodiment, m =2, that is, the vortex generating device group 14 is provided in 2, one is provided in the 4 th concentric tube, and the other is provided in the 3 rd concentric tube. While the concentric tubes 11 of this embodiment correspond one-to-one to the eave structures 13.
This take lampblack absorber of oil smoke separating component compares with embodiment 1, has increased a concentric tube 11, has also increased oil smoke separating component 1 in the inside space volume of shell 2 to reduce the area of 11 air inlets of concentric tube, improved gaseous admission speed, increase the pressure differential of 11 inside and exterior spaces of concentric tube, thereby can improve the separation rate of oil smoke particle.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
