FIG. 3 is a flow chart diagram of an air purifying and holding system in a smoking booth showing an embodiment of the present invention. In the figure, reference numeral 1 denotes an air purifying / holding system in a smoking booth.
The above-described ventilation port 3 and one or more air purifiers 4 are provided, and smoke detection sensors 5 and 6 are provided in the ventilation port 3 and / or around the ventilation port 3.
Is installed. When the smoke detection information from the smoke detection sensors 5 and 6 is the operating condition of the air cleaner 4 set in advance, the air cleaner 4 is operated, and when it is not the set operating condition, the air cleaning is performed. The machine 4 is stopped.

The smoking booth 2 is a room covered with walls and ceilings in this embodiment, but the invention is not limited to this, and there is no problem even if it is surrounded by airflow. The shape is not limited, and in any case, it is within the range of the smoking booth according to the present invention.

The ventilation port 3 is connected to a ventilation duct or the like for constant ventilation, and a filter 10 for removing foreign matter is put on the opening of the ventilation port 3, and the smoke detection sensor 5 is attached inside. A smoke sensor 6 is also attached to the periphery. That is, in the ventilation port 3 for constant ventilation,
Since the smoke existing in the smoking booth 2 will always pass through the ventilation opening 3, if the smoke detection sensor is installed inside or around the ventilation opening 3, or both of them, the fact of smoking will be accurate. Can be sensed. The smoke detection sensors 5 and 6 are not particularly limited, but in order to reliably detect the fact of smoking, a sensor that detects the gas component contained in the cigarette smoke and the dust concentration is preferable.

The type and structure of the air purifier 4 are not limited, and in the embodiment, a direct suction type air purifier 4a and a wall hanging type air purifier 4b are installed. Usually, these air cleaners 4 have a built-in prefilter for removing particles such as relatively large dust, an electrostatic precipitator for removing fine particles after passing through the prefilter, and a deodorizing filter for removing odorous components. , Adopted.

The air purifying and holding system (hereinafter, simply referred to as a system) 1 in the smoking booth has a system control unit 11 as a center, and smoke detection sensors 5 and 6 and air purifiers 4a and 4b are electrically connected to the system control unit 11. Connected. Then, the system 1 operates as follows.
First, the power is turned on and started, and in step 1, the system operation holding timer built in the system control unit 11 is set to, for example, 5 to 10 minutes and turned on to turn on the smoke of the smoke detection sensors 5 and 6. The air purifiers 4a and 4b are not turned on / off violently due to the shake of the sensor, and the process proceeds to step 2 to check the state of the on / off switch of the entire system 1 and proceeds to step 3 to store the data in the switch register. Store to. After that, in step 4, the smoke detection information from the smoke detection sensors 5 and 6 is checked, and step 5

In step 8, the relationship between the smoke detection information data stored in the smoke detection sensor register and the output level of the unit (that is, the air cleaners 4a and 4b) is calibrated in advance as shown in FIG. Data is set in advance, and the smoke detection information data is converted to output data. That is, the output level data is serialized in accordance with the number of step switching such as "strongest", "strong", "medium", "weak", and "weakest". Then, based on this output level data, the output level of the unit (air purifier 4a, 4b) is determined for each stage switching based on FIG. 5 (in FIG. 5, the stage switching is not performed, but the circled portion on the line indicates “ It shows the levels of "strong", "medium", and "weak", and includes 5 steps including "strongest" and "weakest". When the output of the unit is steplessly switched, the output level of the unit is directly determined by the smoke detection information data without going through FIG. In other words, the operation of step 8 described above is simply to determine the output level of the air cleaners 4a and 4b based on the smoke detection information data stored in the smoke detection sensor register. Thereafter, the process proceeds to step 9, the output level data is stored in the unit output register, the process proceeds to step 10, the timer reset flag is set to 1, and the process proceeds to step 11.

In step 11, it is determined whether the logical product of the data stored in the smoke detection sensor register and the data in the switch register is 1 or more. If the determination is YES, the process proceeds to step 12. The unit operation flag is set to 1, and if NO, the process proceeds to step 13, the unit operation flag is set to 0, and the process proceeds to step 14. If the data of the unit operation flag is 1 in step 14, the unit, that is, the air purifier 4a,
If the data of the unit operation flag is 0, the air cleaners 4a and 4b are output as OFF signals and are not operated. Then, in step 15, the output level of the operation of the air cleaners 4a and 4b is changed based on the data stored in the unit output register of step 9. Further, in step 16, it is determined whether the timer reset flag of the system operation holding timer is 1, and if the determination is YES, step 17

The elements 2 and 13 may be attached to the air purifiers 4a and 4b directly or in the vicinity thereof, or may be attached to both of them.

The air purifying and holding system 1a in the smoking booth operates as follows. First, the power is turned on to start, and in step 1, the system operation holding timer built in the system control unit 11a, for example, set to 5 to 10 minutes and turned on to turn on the smoke detection sensors 5, 6 and The air purifiers 4a and 4b are prevented from being violently turned on and off due to the smoke detection blur of the smoke detection sensors 12 and 13, and the system 1a is advanced to step 2.
Looking at the state of the entire on / off switch, the process proceeds to step 3 and the data is stored in the switch register. Thereafter, in step 4, the smoke detection information by the smoke detection sensors 5 and 6 and the specific smoke detection sensors 12 and 13 is checked, and the process proceeds to step 5 to store the data in the smoke detection sensor and the specific smoke detection sensor registers, respectively. In step 6, it is determined whether or not the system operation holding timer is within the set time. If the determination is YES, the timer reset flag is set to 0 and the process proceeds to step 11. If the determination in step 6 is NO, the process proceeds to step 8.

In this step 8, each smoke detection information data stored in the smoke detection sensor and the specific smoke detection sensor register and the unit (ie, the air cleaners 4a, 4a, 4)
The relationship with the output level of b) is set in advance to the calibration data as shown in FIG. 4, and the above smoke detection information data is changed into each output data. That is, each output level data is, for example, “strongest”, “strong”,
It is serialized according to the number of step switching such as “medium”, “weak”, and “weakest”. Then, based on the output level data, the output level of each unit (air purifiers 4a, 4b) is determined for each stage switching based on FIG. When the output of each unit is steplessly switched, the output level of each unit is directly determined by the smoke detection information data without using FIG. In other words, the operation of step 8 described above is simply to determine the output levels of the air cleaners 4a and 4b based on the smoke detection information data stored in the smoke detection sensor and the specific smoke detection sensor register. Is. After that, the process proceeds to step 9 to store the respective output level data in the unit output registers, further proceeds to step 10 to set the timer reset flag to 1, and proceeds to step 11.

In step 11, it is determined whether the logical product of the data stored in the smoke sensor register and the data in the switch register is 1 or more. If the determination is YES. For example, the process proceeds to step 12, each unit operation flag is set to 1, and if NO, the process proceeds to step 13 to set each unit operation flag to 0, and then the process proceeds to step 14. If the data of the unit operation flag is 1 in step 14, it is output as an ON signal of each unit, that is, the air cleaners 4a and 4b to operate, and if the data of the unit operation flag is 0, the air cleaner 4a. 4b OFF signal is output and does not operate. Then, in step 15, the output level of each of the air cleaners 4a and 4b is changed based on the data stored in the unit output register of step 9. Further, in step 16, it is judged whether or not the timer reset flag of the system operation holding timer is 1, and if the judgment is YES, the process proceeds to step 17, the system operation holding timer is reset and returns to step 2, and if NO, step 18 Then, the system operation holding timer is held, the process returns to step 2, and the same operation is repeated thereafter. In addition, when the system 1a is in operation, the air cleaner 4
A and b are all turned on and off at the same time. At the time of turning on, the air cleaners 4a and 4b perform at least the weakest operation so that the smoke detection information from the specific smoke detection sensors 12 and 13 can be picked up.

9 to 11 show an air purifying and holding system 1b in a smoking booth showing another embodiment of the present invention,

The point is that it is electrically connected to the unit 11b. In addition, these human detection sensors 21 and 22 are
It suffices to provide one or more at an appropriate position in the smoking booth 2, and there is no limitation on the position and the number of installations. In this embodiment, a total of two are installed on the side wall and the ceiling.

The air purifying and holding system 1b in the smoking booth operates as follows. First, the power is turned on to start, and in step 1, the system operation holding timer built in the system control unit 11b, for example, is set to 5 to 10 minutes and turned on to turn on the smoke of the smoke detection sensors 5 and 6. Motion blur and human sensor 21, 22
The air purifiers 4a, 4b and the ventilation fan 20 are not turned on / off violently due to the human-detected shake, and the process proceeds to step 2 to check the state of the on / off switch of the entire system 1b, and then proceeds to step 3. Store the data in the switch register. After that, in step 4, the human detection information by the human detection sensors 21 and 22 is viewed, and the process proceeds to step 5 to store the data in the human detection sensor register. Further, in step 6, the smoke detection information by the smoke detection sensors 5 and 6 is checked, and the process proceeds to step 7 to store the data in the smoke detection sensor register. In step 8, it is determined whether or not the system operation holding timer is within the set time. If the determination is YES, the process proceeds to step 9, the timer reset flag is set to 0, and the process proceeds to step 13.
If the determination in step 8 is NO, the process proceeds to step 10.

That is, these output level data are, for example, “strongest”, “strong”,
It is serialized according to the number of step switching such as “medium”, “weak”, and “weakest”. Then, based on these output level data, the output levels of the ventilation fan 20 and the units (air purifiers 4a, 4b) are determined for each stage switching based on FIG. If the output of the ventilation fan 20 and the unit are continuously switched, the ventilation fan 20 can be directly detected by the person detection information and the smoke detection information data without going through FIG.
And the output level of the unit respectively.
In other words, the operation of step 10 described above is simply put in another way, based on the human detection information and the smoke detection information data stored in the registers for the human detection sensor and the smoke detection sensor, the outputs of the ventilation fan 20 and the air cleaners 4a and 4b are output. It is to decide the level.

Then, the process proceeds to step 11 and step 1
1, the output level data of the ventilation fan 20 is stored in the ventilation fan output register and the air cleaner 4
The output level data of a and 4b are stored in the unit output register, the process proceeds to step 12, the timer reset flag is set to 1, and the process proceeds to step 13.

In step 13, the logical product of the data stored in the smoke detection sensor register and the data stored in the human detection sensor register and the logical product of the switch register data are 1 or more. If it is YES, the process proceeds to step 14 to set the unit operation flag and the ventilation fan operation flag to 1. If NO, the process proceeds to step 15 to set the unit operation flag and the ventilation fan operation flag to 0. Set and proceed to step 16. If the data of the unit operation flag is 1 in step 16, the unit, that is, the air cleaners 4a and 4b are output as ON signals to be operated, and if the data of the unit operation flag is 0, the air cleaner 4a,
It outputs as an OFF signal of 4b and does not operate. Similarly,
If the ventilation fan operation flag data is 1, the ventilation fan 20 is output as an ON signal to operate, and if the ventilation fan operation flag data is 0, the ventilation fan 20 is output as an OFF signal and not operated. Then, in step 17, the output levels of the air purifiers 4a and 4b are changed based on the data stored in the unit output register of step 11 and stored in the ventilation fan output register of step 11. Based on the data
The output level of the ventilation fan 20 is changed. Further, in step 18, it is determined whether or not the timer reset flag of the system operation holding timer is 1, and if the determination is YES, the process proceeds to step 19, the system operation holding timer is reset and returns to step 2, and if NO, step 20 Then, the system operation holding timer is held, the process returns to step 2, and the same thing is repeated thereafter.

The air purifiers 4a, 4b, 4c and the ventilation fan 20 are not turned on / off violently due to the motion blur and the motion of the human detection sensors 21, 22 to prevent the air cleaners 4a, 4b, 4c and the ventilation fan 20 from being repeatedly turned on / off.
Looking at the state of the off switch, the process proceeds to step 3 and the data is stored in the switch register. Then, in step 4, looking at the human detection information by the human detection sensors 21 and 22,
Proceeding to step 5, those data are stored in the human sensor sensor register. Further, in step 6, the smoke sensor 5,
By looking at the smoke detection information by 6, the specific smoke detection sensor 1
Looking at the specific smoke detection information by 2, 13, and 14, the process proceeds to step 7 and the data is stored in the smoke detection sensor and the specific smoke detection register. In step 8, it is determined whether the system operation holding timer is within the set time. If the determination is YES, the process proceeds to step 9, the timer reset flag is set to 0, and the process proceeds to step 13. If the determination in step 8 is NO, the process proceeds to step 10.

In step 10, each smoke detection information data stored in the smoke detection sensor and the specific smoke detection sensor register and the unit (ie, the air cleaner 4a,
The relationship between the output level 4b) and the output level is set in advance to the calibration data as shown in FIG. 4, and the above smoke detection information data is changed to the output data. That is, each output level data is, for example, “strongest”, “strong”,
It is serialized in accordance with the number of step changes such as “medium”, “weak”, and “weakest”. Then, according to each output level data, each unit (air purifier 4a, 4a,
The output levels (b, 4c) are determined for each stage switching based on FIG. When the output of each unit is steplessly switched, the output level of each unit is directly determined by the smoke detection information data without using FIG. In other words, the operation of step 10 described above can be simply stated. The output levels of the air cleaners 4a, 4b, 4c are determined based on the smoke detection information data stored in the smoke detection sensor and the specific smoke detection sensor register. It is to be. Similarly, the output level of the ventilation fan 20 is also determined based on the human detection information data stored in the human detection sensor register by following the above procedure. When the system 1c is in operation, the ventilation fan 2
0 and the air purifiers 4a, 4b and 4c are all turned on and off at the same time, and at the time of turning on, the ventilation fan 20 and the air purifiers 4a, 4b and 4c perform at least the weakest operation,
The human detection information from the human detection sensors 21 and 22 and the smoke detection information from the specific smoke detection sensors 12, 13 and 14 can be picked up.

When the output levels of the air cleaners 4a, 4b, 4c and the output level of the ventilation fan 20 are determined in step 10, the process proceeds to step 11. In this step 11, the output level data of the air cleaners 4a, 4b, 4c are stored in the unit output register, and the output level data of the ventilation fan 20 is stored in the ventilation fan output register. Then, the process proceeds to step 12. The timer reset flag is set to 1, and the process proceeds to step 13.

In step 13, the logical sum of the data stored in the smoke detection sensor and the specific smoke detection register and the data stored in the human detection sensor register and the logical product of the data in the switch register are obtained. It is determined whether or not it is 1 or more, and if the determination is YES, step 1
4, the unit operation flag and the ventilation fan operation flag are set to 1, and if NO, the process proceeds to step 15, the unit operation flag and the ventilation fan operation flag are set to 0, and the process proceeds to step 16. If the data of the unit operation flag is 1 in step 16, each unit, that is, the air cleaners 4a, 4b, and 4c are output as ON signals to operate, and if the data of the unit operation flag is 0, the air cleaning is performed. Machines 4a, 4b and 4c are output as OFF signals and are not operated. Similarly, when the data of the ventilation fan operation flag is 1, it is output as an ON signal of the ventilation fan 20 to operate, and when the data of the ventilation fan operation flag is 0, it is output as an OFF signal of the ventilation fan 20. Do not operate. Then, in step 17, based on the data stored in the unit output registers of step 11, the air cleaners 4a, 4b, 4c

It is detected by the smoke detection sensor through the, and the air cleaner can be controlled by the smoke detection information. Therefore, in addition to the above effects, since the ventilation fan is controlled in anticipation of smoke generation, ventilation is suppressed to a necessary minimum, and the air conditioning load is reduced.

According to a fourth aspect of the present invention, the presence or absence of a person in the smoking booth is detected by the human detection sensor, and the air purifier is controlled based on the human detection information. After passing through the purifier and detected by the smoke detection sensor, the air cleaner can be controlled by this smoke detection information. Therefore, in addition to the above effects, by controlling the air purifier as necessary, the ventilation port and ventilation fan can be eliminated, new air conditioning load is not generated, and the air purifier is also efficient. It has the effect of driving well.

According to a fifth aspect of the present invention, the presence or absence of a person in the smoking booth is detected by a human detection sensor, and the ventilation fan is controlled based on the human detection information. It is detected by the smoke detection sensor through the, and all the air cleaners are activated by the smoke detection information, and then the air cleaner that continues to operate is determined by the specific smoke detection information of the specific smoke detection sensor. Stop all air purifiers. Therefore, in addition to the above-mentioned effects, there is an effect that the air cleaner near the smoke generation source and which is most involved in the cleaning is activated.

According to the sixth aspect of the present invention, the presence or absence of a person in the smoking booth is detected by the human detection sensor, and all the air purifiers are operated by the human detection information. Since it passes through the air purifier, it is detected by the specific smoke detection sensor, and thereafter, the air cleaner can be individually controlled by the specific smoke detection information. Therefore, in addition to the above effects,
It is possible to eliminate the ventilation port and ventilation fan, no new air conditioning load is generated, and moreover, the air purifier can be operated efficiently.
