Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
Example one
Referring to fig. 1, a common smoke exhausting apparatus includes a common flue 1, an auxiliary flue 2, a main fan 3, an auxiliary fan 4, and a central controller 5.
A plurality of air inlets 11 are longitudinally arranged on the common flue 1 at intervals and communicated with a smoke exhaust pipeline of a range hood of each layer of user home, and the main fan 3 is arranged at the top of the common flue 1 through a base 31 and used for promoting the discharge of oil smoke in the common flue 1.
The auxiliary flue 2 is hollow and cylindrical, and comprises a first flue 21 extending in the same direction as the common flue 1 in the common flue 1, and a second flue 22 extending outside the common flue 1 and bending at the top end of the first flue 21. The end of the second flue 22 outside the common flue 1 is provided with an auxiliary fan 4, and the auxiliary fan 4 is mounted on an external mounting base (a roof of a high-rise building) through a damping base 41. The auxiliary flue 2 is also simple to install in this way.
The wall of the first flue 21 is provided with a through hole 211 at a position corresponding to a low-rise user, and the through hole 211 coincides with the geometric center of the corresponding air inlet 11. In this application, the lower floor means 1/3 which is not higher than all floors, such as 45 floors in total, and openings are formed at 15 floors and corresponding positions of the floors below (from bottom to top, no more than one third of the air inlet holes 11 are provided with through holes 211). And a lampblack sensor 12 is arranged at each air inlet 11 on the common flue 1. The smoke sensor 12 and the auxiliary fan 4 are electrically connected to the central controller 5, whereby the central controller 5 can control the operation of the auxiliary fan 4 according to a signal of the smoke sensor 12.
When a user normally uses the range hood, the oil smoke sensor 12 at the air inlet 11 of the corresponding public flue 1 detects an oil smoke signal and uploads the signal to the central controller 5; central controller 5 receives the signal after, judges whether for the low level user that through-hole 211 corresponds, if yes, then control auxiliary fan 4 operation, transmits the low level with the negative pressure through auxiliary flue 2, can inhale the oil smoke of low level in auxiliary flue 2 through-hole 211, and then discharges it through auxiliary fan 4, solves the not smooth problem of low level user's exhaust fume.
Through opening of the through holes 211 on the auxiliary flue 2, the backpressure in the smoke exhaust pipeline of the low-level users can be directly reduced, and smoke exhaust of the low-level users is facilitated (when the air quantity is constant, the backpressure in the smoke exhaust pipeline is smaller, and the smoke exhaust effect is better). Therefore, the problem of unsmooth smoke discharge of low-level users can be fundamentally solved, and the phenomena of backward flow, taint of odor and the like of smoke can be improved.
The additional arrangement of the auxiliary flue 2 can reduce the sectional area of the public flue 1, the volume of smoke discharged into the flue by middle and upper users is reduced, and the problems of unsmooth smoke discharge and the like of middle and upper users can be caused, so that the main fan 2 is additionally arranged on the roof for outwards sucking the smoke and reducing the back pressure in a smoke discharge pipeline. Compared with a normal flue, the back pressure in the smoke exhaust pipeline is reduced, and the smoke exhaust effect of middle and upper users is not reduced.
In order to avoid the pipe wall of the auxiliary flue 2 and the pipe wall of the public flue 1 from being too close to each other, the influence of the arrangement of the auxiliary flue 2 on the downward transmission of the negative pressure of the public flue 1 is further reduced as much as possible, the smooth smoke discharge of middle-upper users is ensured, meanwhile, the oil smoke in the lower-layer public flue 1 is ensured to rapidly enter the auxiliary flue 2, and the ratio of the sectional area of the auxiliary flue 2 to the sectional area of the public flue 1 is 1/3-1/2 (the public flue 1 and the auxiliary flue 2 are both hollow cylindrical).
Example two
Referring to fig. 2 and 3, the difference from the first example is that an electric valve 212 capable of opening and closing the through holes 211 is disposed on the wall of the first flue 21 of the auxiliary flue 2 at a position corresponding to each through hole 211, and the electric valve 212 coincides with the geometric center of the corresponding air inlet 11. The electrically operated valve 212 may include a valve and a motor for driving the valve. In the initial state, the electric valve 212 is in a closed state to close the through hole 211, see fig. 2. The electrically operated valve 212 is electrically connected to the central controller 5, and the electrically operated valve 212 is controlled by the central controller 5 in accordance with a signal from the smoke sensor 12.
When a user normally uses the range hood, the oil smoke sensor 12 at the air inlet 11 of the corresponding public flue 1 detects an oil smoke signal and uploads the signal to the central controller 5; after receiving the signal, the central controller 5 determines whether the user is a low-rise user corresponding to the through hole 211, and if so, controls the electric valve 212 at the corresponding floor to open, and the opening mode of the electric valve 212 may be an up-and-down slide or a turning open of the wall, see fig. 3; meanwhile, the central controller controls the auxiliary fan 4 to operate, negative pressure is transmitted to the lower layer through the auxiliary flue 2, oil smoke of the lower layer can be sucked into the auxiliary flue 2 through the through hole 211, and then the oil smoke is discharged through the auxiliary fan 4, so that the problem that a user in the lower layer is not smooth in smoke discharge is solved.
The direct hole opening mode may also cause leakage of the negative pressure on the roof to a certain extent, so that the negative pressure is not enough when the user at a lower floor uses the floor. Assuming that the auxiliary blower of the top building operates to make the negative pressure at the outlet of the auxiliary flue 2 be-100 Pa, the negative pressure transferred to the 3/4/5 floor may be only-40 Pa due to the middle leakage. Therefore, in the embodiment, by arranging the valve at the opening hole, only the valve at the floor used by the user is opened, such as 3/4/5 floors, and the valves at other floors not using the range hood are still kept in a closed state, such as 6-15 floors. Supposing that the auxiliary fan 4 on the top floor works to enable the negative pressure at the outlet of the auxiliary flue 2 to be-100 Pa, the pressure at the outlet of the direct smoke exhaust pipe of 5-layer users is equal to-100 Pa due to the complete sealing of the middle pipeline, so that the 5-layer users can exhaust indoor oil smoke only by small air volume, and the same principle is carried out on 3/4 layers.
