[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to an air purification device that purifies air pollution in a limited range of space, and more particularly to an air purification device suitable for purification treatment of air pollution accompanying smoking in a smoking room or smoking area.
[0002]
[Prior art]
  2. Description of the Related Art As an apparatus for purifying air polluted with smoke or odor, there is an air purifier conventionally equipped with a filter and a blower. What is generally well known is a relatively large amount of processing air that purifies the air in the entire room. In order to purify local air pollution in a limited space such as a smoking room or a smoking area set in a corner of an office or a station, an air purifier having a small amount of processing air has been developed. For example, Japanese Patent Application Laid-Open No. 9-121947 and Japanese Patent Application Laid-Open No. 8-112145 disclose a table having an air cleaning function. These are basically an air purifier in the table body, which purifies contaminated air in a limited space around the table, and is used locally in limited spaces such as smoking rooms and smoking areas. Suitable for air pollution purification.
[0003]
  As shown in FIG. 38, the former of the above publication is provided with a suction port 72 of an air cleaner at the center of a table top plate 71 of the table body 70, and the upper side of the suction port 72 is covered with a shielding plate 73. Ambient air is sucked in a form along the table surface from between the shielding plate 73 and the table top plate 71, and purified air is blown out from one side of the table main body 70. On the other hand, as shown in FIG. 39, the latter is provided with a suction port 72 of an air purifier at the center of the table top plate 71 of the table body 70, purifies the air sucked from the suction port 72, The air is sent to an air blowing part 74 provided on the table top plate 71 and blown from the upper part of the air blowing part 74 toward the suction port 72.
[0004]
[Problems to be solved by the invention]
  In the table having the conventional air cleaning function described above, in the one disclosed in JP-A-9-121947, an air flow toward the suction port 72 is formed in a direction along the table top plate 71. Since the flow velocity of the airflow in the portion in contact with 71 is attenuated and the suction action is extremely weak, and the suction is performed in a limited range between the shielding plate 73 and the table top plate 71, the processing range of contaminated air is narrow. There is a problem. In addition, since the suction action does not work above the shielding plate 73 by the shielding plate 73, when smoked in a standing posture, smoke smoked by smokers and smoke emitted from the cigarettes in hand can be sucked. If you use it while standing face to face, there will also be a situation where the smoke of cigarettes will be blown between the opponents, which is not very good.
[0005]
  In this regard, what is disclosed in Japanese Patent Application Laid-Open No. Hei 8-112145 is to blow down an air flow from the upper part of the air blowing part 74 toward the suction port 72 on the table top plate 71, and to smoke cigarette smoke at the suction port 72. Therefore, even when smoking is performed in a standing posture, the above-described problem does not occur so much. However, since the airflow from the air blowing part 74 is blown down near the user's ear, it must be used while feeling the noise of the ears, which is not very good. Further, in a place where there is an outside wind, the airflow to be blown down is disturbed and removed from the suction port 72, so that it is difficult to effectively suck the cigarette smoke. Furthermore, in any of the above-described tables having the air cleaning function, since the suction port 72 is open on the plane of the table top plate 71, a drink or the like is placed on the table top plate 71, so that it is inadvertent. If it falls, there is also a problem that a drink enters the inside through the suction port 72 and causes a failure of the electrical component.
[0006]
  The present invention is to obtain an air purification device having a wide range of sucking air for purification treatment and excellent in feeling of use, and to obtain an air purification device in which overflowing beverages do not cause failure, and smoking It is to obtain an air purification device capable of more effectively sucking and purifying cigarette smoke accompanying the above, and to promote improvement in usability and function of the air purification device.

DETAILED DESCRIPTION OF THE INVENTION
  Next, embodiments of the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
  The air purifying apparatus according to the first embodiment shown in FIGS. 1 to 4 simply incorporates a mechanism for performing a purification process by continuously sucking air around the box 1 into the box 1 having a trapezoidal structure. The air purifier 2 is composed of the air purifier 2 and the air purifier 2 is devised to deal with various matters related to smoking. It can be installed in a smoking room, part of a station platform, part of a company building It is an apparatus for purifying polluted air generated in a limited space installed in a smoking area.
[0018]
  The basic structure of the air cleaner 2 is that a blower 3 that forms a one-way air flow in a series of ventilation paths that take in the air to be processed and send it to the outside again, and a purification process that purifies the taken-in air to be treated. It incorporates a filter 4 as a functional subject. The ventilation path is configured in the box 1, and the suction port 5 for taking in the air to be processed is opened upward in the center of the top surface 6 of the box 1. A plurality of air outlets 7 that are outlets of the ventilation path are provided at the lower part of the side surface of the box 1 or the bottom surface. The blower 3 is incorporated on the air outlet 7 side of the air passage, and forms an air flow from the air inlet 5 toward the air outlet 7 in the air passage. As the blower 3, a turbo fan is employed in the present embodiment, but other centrifugal blowers such as a sirocco fan and a radial fan may be used. The filter 4 according to the present embodiment includes a pre-filter 8 that collects relatively large particles, an electric dust collector 9 that collects relatively fine particles, and a deodorizing filter 10 that adsorbs gaseous odor components. The pre-filter 8, the electrostatic precipitator 9, and the deodorizing filter 10 are sequentially attached to and detached from the ventilation path between the suction port 5 and the suction port of the blower 3 so that the pre-filter 8 is on the upstream side so as to cross the ventilation path. It is installed as possible.
[0019]
  The box 1 has a structure as an outer shell of the air purifier 2, but a table 11 is provided on the top surface 6 and is configured in a cabinet shape. That is, the height from the floor surface to the table surface 12 of the upper surface of the table 11 of the box 1 is a height at which a person can move his hand, put his elbows, and place objects without feeling uncomfortable. Is formed. The table 11 projects in a flange shape outward from the box 1 on the top surface 6 of the box 1, and the table surface 12 can place an ashtray, drinks, books and baggage. Although the height of the box 1 depends on the physique of the user, it is set to about 800 mm to 1000 mm based on the average adult height of the Japanese. A wheel 13 with a stopper is attached to the bottom of the box 1 so that the entire apparatus can be freely moved to a required place and held in place by the stopper.
[0020]
  On the top surface 6 of the box 1, there is provided a suction dome 15 having a main suction port 14 that surrounds the outer periphery of the suction port 5 and opens upward at a position higher than the suction port 5. The upper end of the suction dome 15 is finished in an R shape by curling over the entire circumference. The main suction port 14 opened at the upper end of the suction dome 15 is provided with a protective lid 16 made of punching metal or mesh in order to prevent entry of foreign matter. The inside of the suction dome 15 is a hollow ventilation path 17, and the main suction port 14 and the suction port 5 of the box 1 are in a positional relationship facing each other vertically. The height of the suction dome 15 may be set appropriately in accordance with the height of the box 1 to prospect the 100Mm～500mm.
[0021]
  The position of the pre-filter 8 may be between the protective lid 16 and the electric dust collector 9, and the position of the deodorizing filter 10 may be a ventilation path between the outlet of the blower 3 and the outlet 7.
[0022]
  If this air purifying apparatus is installed in a smoking room or a smoking place and the blower 3 is operated, the suction action works above the suction dome 15 and around the table surface 12. The ambient air sucked from the main suction port 14 passes through the ventilation path 17 in the suction dome 15 and enters the air cleaner 2 from the suction port 5 of the box 1. The air sucked from the suction port 5 passes through the filter 4, is sucked into the blower 3, and is blown out from a plurality of outlets 7 connected to the discharge port of the blower 3. When the air sucked into the air cleaner 2 passes through the filter 4, first, relatively large particles are collected by the pre-filter 8, and then relatively fine particles are collected by the electric dust collector 9. Odor components in a gaseous state are adsorbed by the deodorizing filter 10 and purified.
[0023]
  The feature of this air purifying device is that the range in which the suction action by the blower 3 works (the area where an air current of about 1 m / s that can suck cigarette smoke and the like is formed) is widened by the presence of the suction dome 15. It is. FIG. 2 shows the measurement results when the height from the floor surface to the table surface 12 is 1000 mm and the height of the suction dome 15 is 250 mm. When the suction dome 15 is not provided, the range in which the suction action is performed is a range surrounded by a solid line A in FIG. 2, and when the suction dome 15 is provided, the range in which the suction action is performed is a range surrounded by a broken line B in FIG. . As the suction dome 15 moves substantially 250 mm upward, the suction working range in the vertical direction is naturally 250 mm higher, but the suction working range in the horizontal direction is working. Is enlarged as shown.
[0024]
  This is because there is no wall surface on the plane where the main suction port 14 of the suction dome 15 opens, and there is no flow rate fixing condition like the wall surface in the suction air flow from the substantially horizontal direction to the main suction port 14, so the suction air flow side is forced. This is because the vehicle is not decelerated. In the absence of the suction dome 15, the suction airflow directed toward the suction port 5 in the substantially horizontal direction is restricted by shear stress due to the presence of the wall surface of the table surface 12 or the top surface 6 of the box 1, and is shown in FIG. 2. Thus, the working range of the suction action becomes narrow. Further, the force for sucking tobacco smoke or the like extends to a space below the plane including the main suction port 14. The suction speed to the main suction port 14 is inversely proportional to the square of the distance from the main suction port 14, but because the distance from the main suction port 14 is short, it is also applied to the table surface 12 below the plane including the main suction port 14. The power to inhale cigarette smoke will work. By increasing the opening area of the main suction port 14, the range in which the suction action in the horizontal direction works can be widened.
[0025]
  Therefore, when this air purification device is used as a smoking place, for example, according to the height dimensions of the box 1 and the suction dome 15 described above, the suction range of tobacco smoke and the like in the vertical direction is about 1000 mm above the floor surface. To about 750 mm above it, for example, a smoker with a height of 1 m80 cm stands on the side of the table 11 and smoke from the mouth and smoke emitted from the cigarette in his hand is sucked from the main inlet 14 and purified. Is possible. Of course, smoke emitted from cigarettes placed on the ashtray placed on the table surface 12 can also be sucked from the main suction port 14 and purified. In this air purifying device, the smoker smokes the opposite position of the table 11 by the function as described above, and it is less likely to cause discomfort such as blowing smoke from the cigarettes that are facing each other. A feeling of use is obtained. In addition, since the main suction port 14 is provided at the upper end of the suction dome 15, even if the table surface 12 overflows drinks or the like, the main suction port 14 does not enter the air purification device, and the overflowing beverage or the like enters. It is possible to prevent electrical components from being damaged.
[0026]
  The shape of the suction dome 15 may be a divergent cone as shown in FIG. 3, or a shape as shown in FIG. Good. Further, as for the shapes of the box 1 and the table surface 12, a square frame shape, a round frame shape, an elliptical frame shape, or the like can be appropriately adopted to adopt a design configuration.
[0027]
Embodiment 2. FIG.
  In the second embodiment shown in FIGS. 5 to 10, the air purifying apparatus shown in the first embodiment is provided with an ashtray 18 as a butt case or ash case accompanying smoking. The configuration of the air purification device itself is the same as that shown in the first embodiment. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0028]
  In the air purifying apparatus according to the second embodiment, a ash ashtray 18 for smoking is provided on the side surface of the suction dome 15 or the table 11 within the range where the suction action works as shown in FIG. The ashtray 18 may be fixed, but it is easier to use because it has poor cleaning properties and can be attached and detached. The mounting / dismounting structure of the ashtray 18 can be configured by embedding or bonding a magnet 19 on the mounting surface of the ashtray 18 as shown in FIG. 6 if the mounting location is made of a magnetic material. Further, as shown in FIG. 7, a hook 20 for latching is provided, and it is configured to be hooked and stopped on the upper end portion of the suction dome 15 or the like, as shown in FIG. You can also Furthermore, the ashtray 18 may be of a drawer type so that it can be taken in and out at the end of the table. As a configuration of the ashtray 18 that can be stored, a configuration in which the ashtray 18 is pivotally supported 22 on the side wall of the suction dome 15 in the lower portion as shown in FIG.
[0029]
  The ashtray 18 is basically provided on the side of the suction dome 15 so that the table surface 12 can be used more widely and is convenient. Moreover, since it will be located in the inner side of the range where the suction action works, the smoke emitted from the cigarette placed in the ashtray 18 can be sucked and purified without escape to the surroundings.
[0030]
  Alternatively, as shown in FIG. 10, a wall 23 surrounding the outer periphery of the suction dome 15 with a gap may be formed, an inclined plate 24 may be provided in the gap, and a drawer-type ashtray 18 may be provided at the lower end of the inclined plate 24. If this configuration is adopted, cigarette ash can be received in a wide range, and the cigarette butt rolls on the inclined plate 24 and is stored together in the ashtray 18, and the cigarette butt is easy to process, so that a smoking area such as a station is used. It becomes an air purification device suitable for a place where many people use. Other configurations and functions are the same as those of the first embodiment.
[0031]
Embodiment 3 FIG.
  In the third embodiment shown in FIG. 11, the shape of the main suction port 14 of the suction dome 15 of the air purification apparatus shown in the first embodiment and the planar shape of the table 11 are configured in a similar shape. The basic configuration of the air purification device itself is the same as that shown in the first embodiment. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0032]
  By configuring the shape of the main suction port 14 of the suction dome 15 and the planar shape of the table 11 to be similar to each other as shown in FIG. 11, the suction action works almost uniformly over the entire circumference of the table surface 12. That is, since the suction speed at a certain point is inversely proportional to the square of the distance from the main suction port 14, for example, by using a circular table 11 with respect to the circular main suction port 14 as shown in FIG. The same suction performance can be obtained regardless of the position of the edge of the table surface 12 where the smoker stands. Other configurations and functions are the same as those of the first embodiment. The third embodiment can also be applied to the second embodiment.
[0033]
Embodiment 4 FIG.
  In the fourth embodiment shown in FIG. 12, the air purification apparatus shown in the first embodiment is devised to improve the suction performance. The basic configuration of the air purification device itself is the same as that shown in the first embodiment. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0034]
  The air purifying apparatus according to the fourth embodiment is provided with an air guide pipe 25 having an inner diameter that gradually decreases, and the air passage between the main suction port 14 of the suction dome 15 and the filter 4 gradually decreases in cross-sectional area toward the filter 4 side. This is a reduced air passage. Thereby, the collision loss of the airflow at the inlet of the main suction port 14 and the vortex loss due to the step at the edge of the suction port 5 are eliminated, and the suction wind speed can be obtained even at a distance far from the main suction port 14. The working range of is expanded. Other configurations and functions are the same as those of the first embodiment. The fourth embodiment can also be applied to the second and third embodiments.
[0035]
Embodiment 5. FIG.
  In the fifth embodiment shown in FIGS. 13 to 18, the air purification apparatus shown in the first embodiment is provided with a downflow airflow generation unit 26 that generates a downflow airflow toward the main suction port 14. . The basic configuration of the air purification device itself is the same as that shown in the first embodiment. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0036]
  In the air purifying device of the fifth embodiment, a chamber 27 capable of taking in ambient air is provided above the main suction port 14 of the suction dome 15, and the main suction port is provided on the lower surface of the chamber 27 facing the main suction port 14. 14 is provided with a downflow airflow generation unit 26 including an air guide member 28 that generates a downflow airflow toward the airflow 14 and a slit outlet 29. The chamber 27 is supported above the suction dome 15 by the support column 30. The inside of the support column 30 is hollow, one end thereof communicates with the chamber 27, and the other end opens as a suction port 31 on the lower surface of the table surface 12, thereby forming a ventilation path to the chamber 27. The support column 30 is provided with a blower 32 that sucks air from a suction port 31 on the lower surface of the table 11 and sends the air into the chamber 27 through a ventilation path. The chamber 27 takes in the air blown by the blower 32 and recovers and homogenizes the air flow, and is configured in a flat disk shape, but the shape is not a problem as long as a volume capable of recovering the air pressure can be secured. . On the lower surface of the chamber 27 facing the main suction port 14, two elongated slit outlets 29 are opened in parallel at an interval, and an air guide member 28 is provided between the two slit outlets 29. The air guide member 28 has a length equal to or greater than the length of the slit outlet 29 in the longitudinal direction, and is configured in a wedge shape in which two air guide surfaces 33 intersect with each other at the lower end forming a ridge angle line 34. A line 34 is provided along the center of the main inlet 14. The slit outlets 29 are arranged along the two air guide surfaces 33 of the air guide member 28.
[0037]
  The downdraft air generation unit 26 generates a sheet-like downdraft toward the main suction port 14, and its function will be described with reference to FIG. By the operation of the blower 32, the air sucked from the suction port 31 opened on the lower surface of the table 11 is sent into the chamber 27 through the ventilation path in the support column 30 that also serves as a support function. The supplied air recovers static pressure in the chamber 27 and is blown out uniformly from the two rows of slit outlets 29. Here, according to the configuration shown in FIG. 15, it is generally known that the blow-off flow rate increases as the distance from the blow-in port 35 to the chamber 27 increases. Therefore, when the static pressure recovery in the chamber 27 is not sufficient, the flow path area becomes narrower as the distance from the blow-in port 35 increases to increase the pressure loss, or a wind direction change vane (not shown) such as an arc shape is blown into the blow-in port. It is desirable to take measures to equalize the flow velocity, such as providing in the chamber 27 close to 35 and actively increasing the air volume in that portion.
[0038]
  The slit-like jets blown out from the two rows of slit outlets 29 become wall jets 36 along the air guide surface 33 of the air guide member 28 due to the Coanda effect, which is one of the fluid phenomena of the jet. It is blown down. The two wall jets 36 merge at a point where the ridge angle line 34 of the air guide surface 33 has passed. The two air guide surfaces 33 are formed so as to intersect at an acute angle as much as possible. The two wall jets 36 are smoothly merged, and after the merge, a single sheet-like airflow 37 is formed. Then, the air is sucked into the suction dome 15 from the central portion of the main suction port 14. In this way, by generating a blow-down airflow 37 from above the main suction port 14 to form a push-pull type cutoff flow, for example, a smoker 38 surrounding the air purification device as shown in FIG. The cigarette smoke 39 blown out toward the downflow airflow 37 collides with the downflow airflow 37 and is forcibly pushed and bent toward the main suction port 14, and is attracted and reliably sucked from the main suction port 14. 1 is purified and blown out from the blowout port 7. Therefore, the smoker of the cigarette does not blow on the smoker who faces, and a favorable feeling of use is obtained. The structure of the suction dome 15 and the air cleaner 2 is the same as that of Embodiment 1, and the function is also the same.
[0039]
  As shown in FIGS. 16 and 17, the downdraft airflow generator 26 opens a rectangular opening 40 on the lower surface of the chamber 27, and an air guide member 28 having an isosceles triangular cross section is formed in the opening 40. It is also possible to provide the side into the chamber 27 and configure the slit outlet 29 between the air guide surface 33 of the air guide member 28 and the mouth edge of the opening 40. According to the configuration of the downflow airflow generation unit 26, the wall surface jet 36 is smoothly formed because the slit outlet 29 is close to the air guide surface 33. The air guide member 28 may be a solid structure, a hollow structure, or a flat structure. However, the air guide surface 33 may be contaminated on the surface, and the smoothness of the surface may be lost. It is desirable that the surface is made of a material that is not easily soiled or coated.
[0040]
  Here, the function of the downdraft airflow generator 26 is clarified by comparing the downdraft airflow 37 generated by the downdraft airflow generator 26 with a general two-dimensional jet. 18A is a cross-sectional view showing the structure of a two-dimensional jet 42 blown out from a single slit 41. FIG. 18B is a cross-sectional view of the slit 43 formed by a wedge-shaped air guide member 28. FIG. It is sectional drawing which showed the structure of the jet flow 44 which was blown out. For comparison, it is assumed that both are blown out at the initial speed of U0, and the amount of blown air and the sum of the blowout width are the same. It is known that the two-dimensional jet 42 blown out from the slit 41 in FIG. 18A spreads at a constant development angle while entraining surrounding gas. If the main suction port 14 of the suction dome 15 is provided below the slit 41 at a distance h, the maximum speed Umax is attenuated at the position of the main suction port 14 and is smaller than the initial speed U0. . According to Rajartnam (jet, Morikita Publishing, p.22, 1980), Umax = 3.50 U0 (h / 1) −^1/2 It becomes the value of.
[0041]
  On the other hand, in the case of being blown out from the two slits 43 by the wedge-shaped air guide member 28 in FIG. 18B, each becomes a wall flow jet 36 that follows the air guide surface 33. In the wall surface jet 36, the surface in which the surrounding gas is entrained is limited to a free shear surface that does not face the wall surface, so that it moves to a wedge-shaped apex (ridge angle line 34) while maintaining a relatively stable state. Can do. Further, since the apex angle is made as acute as possible, the two wall jets 36 smoothly merge at the apex, and as if the blowout origin having a width of 2 l has moved to the apex of the air guide member 28. To the jet 44 having a width of 2 l from the apex. If the height from the slit 43 to the apex of the air guide member 28 is h0, the maximum speed Umax at the point from the slit 43 to h is 3.50U0 {(h−h0) / 1} −^1/2 Thus, it is clearly larger than the single two-dimensional jet 42 blown out from the slit 43. In other words, in order to make the maximum velocity of the jet 44 at the main suction port 14 point a certain value, an initial flow velocity smaller than that in the case of the two-dimensional jet 42 from the slit 41 having a normal width of 2 l is sufficient.
[0042]
  Thus, by providing the downflow airflow generation unit 26 having the configuration as shown in the fifth embodiment, a low-speed and stable downflow airflow 37 is formed toward the main suction port 14, and the table surface 12. The smoke of the cigarette blown out by the smoker can be prevented from reaching the opposite side of the table surface 12.
[0043]
Embodiment 6 FIG.
  This Embodiment 6 shown by FIGS. 19-21 shows the other form regarding the downflow airflow production | generation part 26 of the air purifying apparatus shown in Embodiment 5, and a fundamental structure is Embodiment. This is the same as that shown in the fifth embodiment. Therefore, the same parts as those of the fifth embodiment are denoted by the same reference numerals as those of the fifth embodiment, and description thereof will be omitted.
[0044]
  In the fifth embodiment, the blower 32 for blowing air to the chamber 27 is provided on the lower surface of the table 11 on which the suction port 31 is provided. For example, as shown in FIG. 32 may be incorporated, and a suction port 31 to the chamber 27 may be provided on the upper surface of the chamber 27. By adopting such a configuration, it is not necessary to form a ventilation path in the support column 30, so that the support column 30 can be simplified and reduced in size, and smoke rising above the chamber 27 is allowed to flow from the suction port 31 of the chamber 27. The air can be blown down along with the suction and downflow airflow 37 and conveyed to the main suction port 14. Since the axial flow type blower 32 has a relatively low noise, it can contribute to a reduction in the noise of the entire apparatus. Note that the downdraft airflow generation unit 26 having such a configuration can be configured such that the support 30 is eliminated and the downdraft airflow generation unit 26 can be suspended and supported from the ceiling of the smoking area.

The same. Therefore, the same reference numerals as those of the respective embodiments are used for the same portions as those of the respective embodiments, and description thereof will be omitted.
[0062]
  This air purification device is provided with a pyroelectric human sensor 52 that detects infrared rays emitted by a person and outputs a detection signal, and is configured to be automatically operated depending on whether or not a person is present in the vicinity. . If the human sensor 52 is provided with the chamber 27, it is convenient to arrange the human sensor 52 on the lower surface of the chamber 27 as shown in FIG. In the case where the chamber 27 is not provided, it may be disposed on the side surface of the suction dome 15 or the like. The output of the human sensor 52 is input to the control circuit 53 and processed by a control flow set in advance by the control circuit 53 to control energization to the air cleaner 2. In the case where there is a chamber 27 and generates a blown-down airflow 37 and is provided with a blower 32, the energization of the blower 32 is also controlled. As shown in FIG. 31, the control circuit 53 includes an input signal processing unit 54, a timer count unit 55 that can recognize the elapsed time since the processing signal changed, and an output processing unit 56, and is shown in FIG. The air purifier is automatically operated based on such a control flow.
[0063]
  That is, after the initial setting in FIG. 32, the control circuit 53 processes the input signal from the human sensor 52 in the input signal processing unit 54 (processing of # 1) in S1, and proceeds to S2. In S2, it is determined whether the human sensor 52 has detected a person (processing of # 2). When a person is detected in S2, the power processing switch 56 is turned on by the output processing unit 56 in S3, the process of operating the blower 3 with a strong operation (process of # 3) is performed, and the process proceeds to S5. If no person is detected in S2, the process proceeds to S4, the power switch 57 is turned off (processing of # 4), and the process returns to S2. In S5, the input signal from the human sensor 52 is processed in the input signal processing unit 54 (processing of # 5), and the process proceeds to S6. In S6, it is determined whether or not the human sensor 52 has detected a person (processing of # 6).
[0064]
  If a person is detected in S6, the process returns to S3. If no person is detected, the process proceeds to S7. In S7, a process of weakly operating the blower 3 is performed (# 7 process), and the process proceeds to S8. In S8, the timer count unit 55 performs a process of counting the elapsed time since the person is no longer detected (process of # 8), and proceeds to S9. In S9, a process of determining whether or not the set time has elapsed (process of # 9) is performed. If it has elapsed, a process of turning off the power switch (process of # 10) is performed in S10, and the process returns to S1. If the set time has not elapsed in S9, the process returns to S5.
[0065]
  In addition to such a control method, for example, the control circuit 53 determines the number of people based on the magnitude of the output value of the human sensor 52, and when the number of people is large, the blower 3 is strongly operated to increase the processing air volume. It is also possible to adopt an automatic operation method in which the amount of the processing air flow is reduced by slightly operating 3. By providing such an automatic operation function, the vehicle is operated with an air volume corresponding to the degree of air contamination only when necessary, so that the running cost can be suppressed and energy saving can be imparted.

Can do. The output signal of the miscellaneous gas sensor 58 is input to the control circuit 53 and processed by a control flow set in advance by the control circuit 53 to control energization to the air purifier 2. In the case where there is a chamber 27 and generates a blown-down airflow 37 and is provided with a blower 32, the blower 32 is also controlled. The control circuit 53 includes an input signal processing unit 54, a timer count unit 55, and an output processing unit 56 as shown in FIG. 33, and automatically operates the air purifier based on the control flow as shown in FIG.
[0067]
  That is, after the initial setting in FIG. 34, the control circuit 53 takes the output signal from the miscellaneous gas sensor 58 into the input signal processing unit 54 in S21, and performs A / D conversion in S22 to obtain an A / D conversion value X (miscellaneous gas). The density is determined, and the process proceeds to S23. In S23, it is determined whether X is greater than a preset density value A. If it is not larger, the power switch 57 is turned off in S24, and the elapsed time after the processing signal is changed in the timer count unit 55 is counted in S25 and the process proceeds to S26. In S26, it is determined whether or not the set time has elapsed. If it has elapsed, the process returns to S21, and if it has not elapsed, the process returns to S24. If A <X in S23, the process proceeds to S27, performs a process of weakly operating the blower 3, performs a timer count process in S28, and proceeds to S29. In S29, it is determined whether or not the set time has elapsed. If it has elapsed, the process proceeds to S30, and if not, the process returns to S27.
[0068]
  In S30, the output signal from the miscellaneous gas sensor 58 is taken into the input signal processing unit 54. In S31, A / D conversion is performed to obtain an A / D conversion value X, and the process proceeds to S32. In S32, it is determined whether X is smaller than a preset density value a. Here, density value A> density value a. If X <a in S32, the process proceeds to S24, and if X <a, the process proceeds to S33. In S33, it is determined whether X is greater than a preset density value B. Here, the density value B is higher than the density value A. If B <X in S33, the process proceeds to S34, and if B <X, the process returns to S30. In S34, a process of strongly operating the blower 3 is performed. In S35, a process of counting the timer is performed, and the process proceeds to S36. In S36, it is determined whether or not a predetermined time has elapsed. If it has elapsed, the process proceeds to S37, and if not, the process returns to S34.
[0069]
  In S37, an output signal from the miscellaneous gas sensor 58 is taken into the input signal processing unit 54, and in S38, A / D conversion is performed to obtain an A / D conversion value X, and the process proceeds to S39. In S39, it is determined whether X is smaller than a preset density value b. Here, density value B> density value b. Further, density value b ≧ density value A. If X <b in S39, the process returns to S27, otherwise returns to S37. Note that the timer count unit 55 recognizes the elapsed time since the change of the processing signal, and prevents the chattering operation by processing whether or not the set time has elapsed. By providing such an automatic operation function, the vehicle is operated with an air volume corresponding to the degree of air contamination only when necessary, so that the running cost can be suppressed and energy saving can be imparted.
