  The air purifier 1 in FIG. 18 is provided with the ventilation mechanism as described above, and the duct joint 31 of the outside air introduction opening 30 (here, used as a circulating air suction port) of the purifier main body. Is connected to a suction duct 100 having a terminal portion branched into a plurality of portions. The terminal portion of the suction duct 100 is connected to a grill G1 (see FIG. 17) provided on the ceiling of the living rooms R2 to R5. In addition, a duct 101 having a tip branched into a plurality of parts is connected to the circulating air outlet 26 of the purifier main body in order to send clean air to the living rooms R2 to R5. An outlet grill G2 is connected to the end of the duct 101. Further, the exhaust duct 28 communicates with the outside of the building. The exhaust opening 25 of the cleaner main body 1 opens from the ceiling of the hallway toward the hallway, but is covered with a cosmetic front panel having a ventilation opening, and is sucked from the exhaust opening 25 by the exhaust fan 33. The air is discharged outside the building via the duct 28.

  According to the structure of this building, the air in the rooms of the separate rooms R2 to R5 is collected via the duct 100, intensively cleaned by the air cleaner 1, and returned to the rooms of the rooms R2 to R5 again. Air purification of the entire building can be performed intensively, and air supply and exhaust can be controlled for each room by providing opening / closing members such as shutters in the ducts 100 and 101. For this reason, it is low cost and advantageous for energy saving. Furthermore, since the entire building can be ventilated by the ventilation mechanism, not only air cleaning but also ventilation can be intensively controlled.

  The air purifier 1 in FIG. 19 is provided with a ventilation mechanism as described above. A duct 101 whose tip is branched into a plurality of parts is connected to the circulating air outlet 26 of the main body of the cleaner in order to send clean air to the living rooms R2 to R5. An outlet grill G2 is connected to the end of the duct 101. Further, the exhaust duct 28 communicates with the outside of the building.

  According to the structure of this building, the air in the rooms of the separate rooms R2 to R5 is collected via the duct 100, intensively cleaned by the air cleaner 1, and returned to the rooms of the rooms R2 to R5 again. It is possible to concentrate the air purification of the room of the whole building or to clean the air for each room of the building, which is low cost and advantageous for energy saving. Furthermore, since the entire building can be ventilated through undercuts such as the doors of the rooms R2 to R5 by the ventilation mechanism, it is possible to control intensively including not only air cleaning but also ventilation.

  FIG. 20 shows a modification of the building structure of FIG. 19, and either or both of the dust sensor S1 and the odor sensor S2 are installed on the ceilings or walls of the rooms R2 to R5. The dust sensor S1 and the odor sensor S2 are connected to a control circuit 29, and the dust sensor S1 or the odor sensor in any of the rooms R2 to R5 is added to the drive program for the air supply motor 17 and the exhaust motor 18 of the microcomputer of the control circuit 29. When S2 detects dust or odor, the rotational speed of the air supply motor 17 or the exhaust motor 18 is increased to promote air purification and ventilation.

  Further, for example, air volume adjusting means such as a damper or a shutter is provided at a branching portion of the duct 101 that branches into each of the rooms R2 to R5, and a driving mechanism (motor, gear, cam, link mechanism, etc.) is provided in the damper or the shutter. ), A relay of commercial power supply is provided in a motor such as a damper or a shutter, and this relay is controlled by the control circuit 29, and the dust sensor S1 or the odor sensor S2 in any of the rooms R2 to R5 is provided. When no dust or odor is detected, the control circuit 29 may close the duct 101 branched by a shutter or a damper for the rooms R2 to R5 where no odor or dust is detected.

  FIG. 21 shows that the main body of the air cleaner 1 is installed on the ceiling of one room R2 (for example, a living room), and the air in the room R2 is cleaned and the room air is exhausted for circulation in the bottom plate portion of the air cleaner 1. An example in which air is sucked from the suction port 7 and the exhaust opening 25 will be described.

  Here, when the air is circulated, the purified air is sent out from the part of the duct 101 of the circulation outlet 26 to the room R2. For the other room R3 (living room), the room air is sucked in by the duct 100 to clean the air, and the air cleaned by the duct 101 is sent out to the room R3. For the rooms R4 and R5 (living room) The air can be purified by sucking room air through the duct 100 or the air cleaned by the duct 101 can be sent to the room R3.

  FIG. 22 shows a configuration example when either or both of the dust sensor S1 and the odor sensor S2 are installed in the rooms R3 and R4. Since the control method of the air cleaner 1 in this case is the same as that described with reference to FIG.

  In FIG. 23, the lighting switches S3 in the rooms R2 to R5 are connected as elements for controlling the control circuit 29. As shown in FIG. 24, when the lighting switch S3 is connected to a commercial power source, the control circuit 29 transmits a part of the current that is interrupted by the lighting switch S3 to the control circuit 29, so that the control circuit 29 can control the lighting switch S3. It can be detected that is turned on or turned off. If the lighting switch S3 is ON, the air supply motor 17 that controls the air cleaning function and the exhaust motor 18 that controls the exhaust perform normal automatic operation (there is also control of the number of rotations by the sensors S1 and S2). If S3 is OFF, the air supply motor 17 and the exhaust motor 18 perform automatic operation with a reduced air volume (there is also a control of the number of rotations by the sensors S1 and S2).

  As a result, it is possible to reduce the sound of a room where there is no person or a room that has gone to sleep, and a quiet sleep state can be secured.

  FIG. 25 shows the air cleaners 1 in a plurality of rooms connected by control lines. In the air purifier system of FIG. 25, when the operation of the air purifier 1 in a certain room R2 starts, the air purifiers 1 in the other rooms R3 and R4 also start to operate and draw a wider range of air. It is configured so that it can be cleaned.

  That is, when sensors or switches such as the dust sensor S1 or the odor sensor S2 are arranged in a plurality of indoor places (rooms R2 to R5, etc.), and any of those sensors or switches is turned on or turned off. The operation of the plurality of air purifiers 1 is started or stopped. The control circuit 29 of each air cleaner 1 is connected by a control line so that control signals can be exchanged with each other. When one of the air purifiers 1 is activated or the dust sensor S1 or the odor sensor S2 is turned on, the other air purifiers 1 also enhance the air purifying function and the exhaust function to purify and ventilate the entire building. Is what you do.

  FIG. 26 is a modification of FIG. 25, in which a plurality of air purifiers 1 are connected to each other by communication lines or control lines C1, and either or both of the dust sensor S1 and the odor sensor S2 of each air purifier 1 are used. When dust or odor is detected, the detection results are transmitted to each other, and air purification and exhaust (ventilation) are simultaneously performed with predetermined operation contents.

  For example, there may be a case where a plurality of air purifiers 1 perform control such as air cleaning or ventilation at the same time or at times determined at different times, air flow, or the like. Using a network device, it is also possible to command air cleaning from the outside, monitor air conditions, monitor indoor equipment, etc. In this example, a wide living room, corridor, etc. Air purification and ventilation of the room or the indoor space can be performed quickly at the same time.

  In FIG. 27, the air cleaner 1, the intermediate duct fan 110, and the pipe fan 111 are connected by control lines C1 and C2. The intermediate duct fan 110 includes a fan and a fan motor (not shown), and can suck air from the suction duct 112 and discharge the air sucked from the discharge duct 113 to the outside. In addition, the pipe fan 11 is configured to be able to discharge indoor air to the outdoors by rotating the motor to move the fan. Although the air cleaner 1 includes the exhaust duct 28, the exhaust duct 28 may be omitted. When either the dust sensor S1 or the odor sensor S2 built in the air purifier 1 senses dust or odor, the speed of the motor is increased so that the air purifier 1 also enhances the air purifying function and the exhaust function (ventilating function). At the same time, a control signal for increasing the rotational speed is also sent to the motors of the pipe fan 111 and the intermediate duct fan 110 to enhance the exhaust (ventilation) function. Therefore, the intermediate duct fan 110 and the pipe fan 111 can be connected to the microcomputer of the air purifier 1 so that these relays can be controlled without installing a microcomputer or the like by installing a relay or the like in the motor power circuit. The drive control of the intermediate duct fan 110 and the pipe fan 111 can be performed by the microcomputer control of the air purifier 1.

  In addition, the ventilation function of the air cleaner 1 is provided with a constant ventilation mode in which ventilation is performed for 24 hours (always), and in addition to the constant ventilation function of other ventilation devices of the intermediate duct fan 110 and the pipe fan 111. In total, the predetermined ventilation frequency (for example, 0.5 times / h) of the volume of the ventilation target area of the house (if the ventilation target area of the whole house or the ventilation target area for each floor when there are multiple houses) It comes to satisfy.

  When either the dust sensor S1 or the odor sensor S2 senses, the drive of the intermediate duct fan 110 and the pipe fan 111 is controlled to increase the rotation speed of the motor, but the room does not sense odor or dust. With regard to, by controlling the motor rotation speed to lower the ventilation air volume, the total ventilation is controlled so as to approach the constant ventilation volume.

  For example, when the pipe fan 111 is installed in a room where odor or dust is detected, the motor speed of the pipe fan 111 is increased to increase the ventilation amount. As the ventilation amount of the target area such as the entire house is decreased, the number of ventilations is controlled so as to satisfy a predetermined number of ventilations and to be constantly close to a constant value.

  Further, in the winter season, when the predetermined ventilation frequency (for example, 0.5 times / h) is reduced (for example, 0.3 times / h), only the intermediate duct fan 110 and the pipe fan 111 are driven, You may make it satisfy | fill predetermined ventilation frequency. Switching to the winter mode may be performed by a switch provided on the remote controller, or the date may be input to a remote controller installed in the room to automatically reduce the ventilation volume for 24-hour ventilation. . Furthermore, although the air cleaner 1 controls a plurality of ventilation devices such as the intermediate duct fan 110 and the pipe fan 111, other devices such as a ventilation device or a single device may be used. The sensor S1 or the odor sensor S2 is installed in the air cleaner 1, but may be installed in a remote controller or other room.

  FIGS. 28A and 28B show an example in which the intermediate duct fan 110 or the bathroom ventilator 120 is connected to the air cleaner 1 in the room R2. In this example, when the switch is turned on so that the air cleaner 1 is operated, or when odor or dust is detected by a sensor built in the air cleaner 1 or a sensor provided in the room, the intermediate duct fan 110 is used. Alternatively, the bathroom ventilator 120 is driven to ventilate the room air.

  In the operation of the intermediate duct fan 110, room air is sucked from the duct 114 in the room R2, and is discharged to the outside through the exhaust duct 112. In a room where the indoor air suction duct is not provided, the room air collected in the ducts 113, 114, 115 through the undercut portion U of the door is discharged indoors or outdoors. The bathroom ventilation device 120 may be a bathroom air conditioner such as a bathroom dryer having a clothes drying function or a heating function.

  FIG. 29 shows an example in which a ventilation device that is a supply / exhaust unit 116 is connected to the air cleaner 1 in the room R2. The heat exchange type ventilator 116 of FIG. 29 has the above-described 24-hour (above) ventilation function, and is provided with a heat exchanger such as a total heat exchanger, and an outside air introduction duct 117 and an outside air introduction fan (not shown). ), The outside air is taken in and supplied to the room via the air supply duct 118.

  In addition, indoor air is sucked through an undercut portion between the door and floor of each room, and an indoor air suction port provided on the lower surface of the main body of the heat exchange type ventilator installed at a predetermined position such as a hallway (Not shown) is sucked in by an exhaust fan (not shown). The indoor air sucked into the heat exchange type ventilator exchanges the outside air introduced into the heat exchange type ventilator with latent air and sensible heat by an outside air introduction fan (not shown), and is discharged to the outside. ing.

  Note that the heat exchanger of the heat exchange type ventilator does not exchange latent heat and sensible heat, but may be a sensible heat exchanger.

  When odors or dust are detected by the main body of the air cleaner 1 or a sensor provided in the room, the air cleaner 1 is operated to purify the room air, and the heat exchange type ventilator 116 is driven to remove the room air. Ventilate to exhaust and supply outside air into the room. The heat exchange type ventilator 116 may operate in conjunction with the air purifier 1 or may operate only with the ventilator 116.

  Instead of the heat exchange type ventilator 116, the air supply unit may be configured to supply outside air into the room. In this case, in conjunction with the intermediate duct fan 110 shown in FIG. 28 (a), outside air is supplied into the room by the air supply unit while operating the air cleaner 1 according to the detection result of the sensor. The indoor air may be discharged by the duct fan 110.

  The air purifier 1 has a continuous (24 hours) ventilation function that is driven continuously or intermittently, and can always discharge harmful substances such as formaldehyde and VOC, which have recently become problems. Further, the intermediate duct fan 110 in FIG. 28A and the bathroom ventilator 120 in FIG. 28B also have a 24-hour (always) ventilation function, and the volume of a predetermined area is 0.5% of the volume of the entire house. The ventilation frequency of times / hour (h) is satisfied.

  In this case, only the intermediate duct fan 110 and the bathroom ventilator 120 may satisfy the ventilation frequency, but in that case, there is a possibility that the apparatus such as the fan or the motor will be enlarged. However, by using the ventilation function of the air cleaner 1, the ventilation function of the air cleaner 1, the intermediate duct fan 110, the bathroom ventilator 120, etc. can be obtained without increasing the size of the intermediate duct fan 110 and the bathroom ventilator 120. The constant ventilation function of multiple devices makes it possible to meet the required ventilation frequency of the house.

  In winter, the predetermined ventilation frequency (for example, 0.5 times / h) may be decreased (for example, 0.3 times / h). In that case, the motor speed is controlled to be lowered so that the ventilation amount during the 24-hour constant ventilation function (mode) of the intermediate fact fan 110 and the bathroom ventilation device 120 is lowered. Switching to the weak ventilation mode such as winter mode can be done with the switch provided on the remote controller. When the date is entered in the remote controller installed in the room and it becomes winter, it is automatically 24 hours. You may make it reduce the ventilation volume of ventilation.

  When the dust sensor S1 and the odor sensor S2 are detected and the ventilation amount is increased by increasing the rotation amount of the ventilation motor 18 of the air cleaner 1, the fan motors of the intermediate duct fan 110 and the bathroom ventilation device 120 are increased. Control is performed so that the rotation speed is low and the ventilation volume is reduced, so that the entire house is close to a constant air volume.
