Description
Technical field
The present invention relates to a kind of building common ducts, more particularly, to a kind of building common duct smoke evacuation system and its control
Method.
Background technique
Currently, high residential building is more and more, high-storey smoke evacuation mostly uses common flue central exhaust, and house height increases
Add, the resistance in entire smokejack is caused to increase.The outlet of high-rise common duct is generally located at the top of floor, and range hood
The power of offer is limited, causes smoke discharging effect undesirable, cooks peak period, lowrise layer oil smoke can not arranged, or even flue occurs
In oil smoke flow backward phenomenon.Currently, there has been proposed " central purge systems in order to solve the problems, such as that existing kitchen ventilator is discharged fume unsmooth
The concept of system ", the main air blower by being placed on common flue top generates power, and cooperates the cooking-fume exhauster blower of user side
To promote smoke discharging effect.However, not only breaking up the dynamic flat of blower due to easily accumulating fat particles on the blade of the main air blower of roof
Weighing apparatus causes noise to increase, vibration aggravation, but also periodic cleaning is needed to safeguard, maintenance is cumbersome.Also, main air blower is arranged
On common air exhaust passage, the increase of system exhaust resistance will lead to.Especially when number of floor levels is greater than 35 layers, attic main air blower
The negative pressure of generation can not be handed on effectively, the case where leakage pressure occur, and discharging fume on low layer user, it is almost nil to influence, and be caused instead
Energy waste.In conclusion needing to be further improved existing common duct smoke evacuation system.
Summary of the invention
First technical problem to be solved by this invention is for above-mentioned state of the art, and providing a kind of can pass through flue
The extractor fan of bottom enhances the building common duct smoke evacuation system of chimney meatus transmitting smoke ability.
Second technical problem to be solved by this invention is for above-mentioned state of the art, and providing one kind can be realized
The control method of the good building common duct smoke evacuation system of intelligentized control method, energy-saving effect.
The present invention solves technical solution used by above-mentioned first technical problem are as follows: building common duct smoke evacuation system
System, the range hood including being mounted on different floors, the air outlet of every range hood pass through respective smoke pipe and public cigarette
Road is connected, it is characterised in that: the exhausting that the gas in flue is taken out outward can be filled by being equipped in the bottom of the common duct
It sets, further includes having the control system that can accordingly control the extractor fan according to the size of Homes Using TV.
Preferably, the starting-up signal of the range hood is transmitted to the control system by radio transmitting device, described
Control system calculates the Homes Using TV according to starting-up signal.
Control system may be mounted at multiple positions, it is preferable that the control system is mounted on the common duct lower part
Outer wall on.
In order to be purified, be filtered to the oil smoke extracted out from common duct, the common duct bottom has to be filled with exhausting
The lower air outlet that air inlet is connected is set, filter device is installed in the air duct between the lower air outlet and air inlet.
In order to remind user replace filter device, first pressure sensor is installed in the front end of the filter device,
Second pressure sensor is installed in the rear end of the filter device, the first pressure sensor and second pressure sensor
Signal output end and the signal input part of the control system are electrically connected.
The present invention solves technical solution used by above-mentioned second technical problem are as follows: the building common duct smoke evacuation system
Control method, it is characterised in that include the following steps:
1., the total number of floor levels N of input；
2., the booting of indoor range hood, control system counts n according to collected starting-up signal, calculates Homes Using TV η=n/
N；
3., as η < 20%, extractor fan does not work；As 20%≤η < 40%, the work of extractor fan low-grade location；When
When 40%≤η < 60%, the work of extractor fan middle gear；When η >=60%, the work of extractor fan high tap position.
Further preferably, the step 3. in extractor fan it is in running order under, the first pressure sensor
It starts to work with second pressure sensor, and the exhausting dress that the first pressure sensor and second pressure sensor detect
The pressure differential Δ P for setting rear and front end is transferred to the control system, also, in the state of Δ P >=100Pa, prompts to replace
Filter device.
Compared with the prior art, the advantages of the present invention are as follows: the building common duct smoke evacuation system can pass through stack base
Extractor fan low layer oil smoke is discharged, reduce the pressure of stack base, to promote the smoke evacuation ability and smoke exhaust efficiency of flue,
Low layer user smoke evacuation is unsmooth when solving the problems, such as culinary art peak, returns cigarette alters taste, improves user experience, also, the control
System processed accordingly can control the operation range of extractor fan according to the size of Homes Using TV, to realize the intelligence of smoke evacuation system
Energyization control, and keep system more energy saving.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention；
Fig. 2 is the control logic figure of the control method of the embodiment of the present invention；
Fig. 3 is the control logic figure of the filter device of the embodiment of the present invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
