This cigarette machine with self-cleaning function can carry out seven layers of separation to the oil smoke in the use, finally discharges through the gas outlet in nearly clean gas again. The seven-layer separation is specifically as follows:
the seven-layer separation is specifically as follows:
first layer separation, inertial separation: the oil smoke enters the interior of the range hood through the first air inlet 2011 of the shell 201, and the oil smoke enters the first arc-shaped sheet 2012 after entering the first air inlet 2011 of the shell 201, so that the air flow speed is accelerated due to the pressure difference between the interior of the shell 201 and the external environment and the sudden change of the area of the first air inlet 2011, and the inertia momentum is relatively increased. And the oil smoke can form a very thin boundary layer around the arc-shaped sheet, and because the first air inlet 2011 of the shell 201 forms an included angle with the first arc-shaped sheet 2012, the oil smoke is forced to flow upwards and enter the oil smoke separator 100 after flowing downwards along the first arc-shaped sheet 2012, so that the heavier oil moves downwards separately from the crude oil smoke flow field in the downward inertial motion and is collected in the oil collecting device 202 at the bottom of the shell 201, 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 direction of the first arc-shaped sheet 2012 from the downward-upward flowing flow, and the oil smoke particles cause an unstable flow field under the flow field separation, so as to further form a vortex. The flow field or the vortex flow interacts with the adjacent flow field or the vortex flow, a continuously rotating flow field is formed on the first arc sheet 2012, and the rotating vortex flow reaches the maximum vortex amount at this time. The remaining lighter oil smoke will not stop at the rotating vortex of the first arced sheet 2012 and when a certain weight is accumulated, the flow field will not support the weight of the oil drop and will fall down or flow along the first arced sheet 2012 to the oil collecting device 202.
Third layer separation, centrifugal separation: the ring sectors 105 rotate with the concentric tube of oil 110 creating centrifugal force which interacts with the suction of the fan. After the first separation, the remaining light oil smoke firstly contacts the outermost end of the ring-shaped fan sheet 105 and then enters the concentric tube 110 when entering the concentric tube 110, the centrifugal force at the outermost end of the ring-shaped fan sheet 105 can enable a part of the fluid or the oil smoke particles to be separated or blocked to enter the concentric tube 110 and move outwards, then the fluid or the oil smoke particles are thrown onto the first arc-shaped sheet 2012 of the shell 201 of the range hood at a high tangential velocity, and the oil smoke on the first arc-shaped sheet 2012 is thrown onto the shell 201 again.
Fourth layer separation, inertial separation and centrifugal separation: inertial separation and centrifugal separation: after the third layer separation, the remaining oil smoke with lighter weight is subjected to the centrifugal force and the attraction force at the same time, but the relative attraction force is larger than the centrifugal force. Some of the oil smoke will flow to the adjacent ring-shaped fan blades 105 through the through holes 106, 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 of the ring-shaped fan blades 105 again at a higher tangential speed due to the centrifugal force effect, and will be thrown onto the housing 201 again.
Fifth layer separation, cyclonic centrifugal force and secondary vortex generation of concentric tubes 110: the concentric tube 110 rotates to form a cyclone, the concentric tube 110 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 rotate without stopping, so that the oil smoke is captured and is not allowed to escape from the pipeline. When the attraction force and the centrifugal force are removed, the oil smoke which continuously rotates from the secondary vortex and moves at the high tangent line of the pipe wall flows downwards along the inner pipe wall due to the gravity.
Sixth layer separation, secondary vortex generating assembly 107 separation: the secondary vortex generating component 107 at one end of the concentric tube 110 generates flow field separation on the remaining oil smoke, and by means of the flow field separation, part of the oil smoke is blocked by the instability of the flow field and does not flow upwards and capture the oil smoke from the rotating vortex.
Separating a seventh layer, and separating by centrifugal force of a fan: after the first four layers of separation, a small amount of very light oil smoke particles are discharged from the airflow formed by the rotation of the fan in the air draft assembly 203 due to pressure difference, the rotating fan forms centrifugal force to throw the remaining small amount of oil smoke particles onto the inner wall of the fan, and finally nearly clean air is discharged outside through the air outlet.
According to the cigarette machine with the automatic cleaning function, when the cigarette machine receives a stop work command, the cigarette machine in the self-cleaning mode is started, and the cigarette machine is provided with a cigarette machine main body, an oil smoke separator and a cleaning program controller; the oil smoke separator is fixedly assembled on the smoke machine main body, and the cleaning program controller is respectively and electrically connected with the smoke machine main body and the oil smoke separator; and when the cleaning program controller receives the command of stopping the cigarette machine main body, the cleaning program controller starts to control the oil smoke separator assembled in the cigarette machine main body to start a self-cleaning mode.
When the cleaning program controller receives a signal that the range hood stops working, the cleaning program controller starts to control the range hood air exhausting assembly and the oil smoke separator to start a self-cleaning mode. When oil smoke separator is about to the stop work time, the rotating electrical machines in clean program controller through control convulsions subassembly and the oil smoke separator, begin to rotate, rotating electrical machines, it begins to rotate to drive multistage oil smoke separation main part through the rotation axis, on all getting rid of the shell of cigarette machine main part with solids such as adnexed greasy dirt in the multistage oil smoke separation main part, and also rotate because the convulsions subassembly of cigarette machine, make the greasy dirt of throwing away can not get rid of other places, avoided the lampblack absorber in the use because the be difficult to abluent vexation that the long-term absorption of greasy dirt caused. The cigarette machine with the automatic cleaning function has the characteristics of simple structure and convenience in use.
