In FIG. 2, a part of the side surface of the air purifier 100 is covered with a synthetic resin side suction port forming member 103 which is one of the casing members. The side suction port forming member 103 is formed with a first side suction port 111 that takes in air so as to extend in the vertical direction. That is, as for the 1st side suction inlet 111, the vertical dimension is larger than the horizontal dimension. Although not shown, a part of the side surface on the opposite side of the air cleaner 100 is similarly covered with the side suction port forming member 103. The side suction port forming member 103 is formed with a second side suction port 112 extending in the vertical direction at a position facing the first side suction port 111. The vertical and horizontal dimensions of the second side suction port 112 are the same as the dimensions of the first side suction port 111. Hereinafter, when referring to all of the first side suction port 111, the second side suction port 112, and the lower suction port 113, the suction port 110 is used.

Detailed configuration
<Electric dust collector 200>
FIG. 4 is an exploded view in which a part of the casing member such as the front panel 102 is removed from the air cleaner 100. As shown in FIG. 4, the electrostatic precipitator 200 (dust collecting auxiliary device) has a vertically long cylindrical shape, and includes a first side suction port 111 and a second side suction port 112. Are installed detachably, one by one in the vicinity of each other, vertically along each suction port 110. The electrostatic precipitator 200 charges relatively small dust floating in the sucked air. The electrostatic precipitator 200 disposed in the vicinity of the first side suction port 111 is a discharge unit L201. The electrostatic precipitator 200 disposed in the vicinity of the second side suction port 112 is a discharge unit R202. The vertical and horizontal dimensions of the electrostatic precipitator 200 are larger than the vertical and horizontal dimensions of the suction port 110, and the electrostatic precipitator 200 is in contact with the side suction port forming member 103 so that there is no gap between them. Therefore, all the air sucked from the suction port 110 is configured to pass through the electric dust collector 200.

  FIG. 6 is an external view of the discharge unit L201. FIG. 7 is a cross-sectional view of the discharge unit L201. The discharge unit L201 includes a synthetic resin casing 210 having a vertically long cylindrical shape. As shown in FIG. 6, the casing 210 is vertically divided into a casing first part 211 and a casing second part 212. As shown in FIG. 7, the casing first part 211 and the casing second part 212 are separated. Are connected by a hinge 213.

  The casing first portion 211 holds a tungsten ionization wire 231 that is a positive electrode of the two positive and negative electrodes. The negative electrode is held by the casing second part 212. The negative electrode is a stainless steel plate-like electrode (electrode plate 232).

  An electrode plate 232 that is a negative electrode is attached to the inside of the casing second part 212. The electrode plate 232 is shaped to form three opposing walls parallel to the longitudinal direction of the casing second portion 212. Here, for convenience of explanation, of the three walls, the middle wall is referred to as a middle wall 232b, and the left and right walls of the middle wall 232b are referred to as a left wall 232c and a right wall 232a, respectively. The left wall 232c and the right wall 232a are accommodated in a space formed by the casing second portion 212. On the other hand, the middle wall 232b protrudes about several millimeters from the space.

  As shown in FIG. 7, the edge of the casing first part 211 and the edge of the casing second part 212 are in contact with each other. In a state where the hinge 213 is closed, the ionization line 231 is located in a space formed by the casing second portion 212 and surrounds the middle wall 232b in a U shape. Further, the U-shaped ionization line 231 is surrounded by the left wall 232c and the right wall 232a from the outside. That is, the ionization line 231 is located between the left wall 232c and the middle wall 232b, and between the middle wall 232b and the right wall 232a, and in a state parallel to each wall, the ionization line 231 is appropriate for the wall and the discharge. Keep the distance of.

  When a high voltage is applied to the ionization line 231, a potential difference is generated between the two electrodes, and one kind of corona discharge is generated between the two electrodes at a portion where the ionization line 231 and the electrode plate 232 face each other. The part where the discharge occurs is called a discharge generation part.

  In the portion covering the discharge generating part (lattice part 200a), the casing first part 211 and the casing second part 212 are in a lattice shape. Further, the outer side of the lattice portion 200 a of the casing first portion 211 is covered with a pre-filter 219. The outer side of the lattice part 200a of the casing first part 211 corresponds to the upstream of the airflow of the sucked air. The sucked air enters the casing 210 from the lattice part 200a and passes through the discharge part. The dust in the air that passes through is charged by electric discharge.

<Filter unit 310>
As shown in FIG. 3, the filter unit 310 includes a pre-filter 311, a HEPA (High Efficiency Particulate Air Filter) filter 312 (dust collection filter), and a deodorizing element 313. First, large dust is removed by the pre-filter 311. Next, finer dust is removed by the HEPA filter 312. Further, the air that has passed through the HEPA filter 312 is decomposed or adsorbed by formaldehyde, odor components, and the like by a deodorizing element 313 containing activated carbon or the like.

<Streamer discharge unit 340>
A part of the air blown out from the sirocco fan 350 is sent to the streamer discharge unit 340 (active species supply means) as a tributary 502 shown in FIG. When this tributary 502 passes through the streamer discharge unit 340, the active species is supplied by the streamer discharge. The tributaries 502 supplied with the active species are blown out from the discharge port 331 to the front of the pre-filter 311 as a plurality of divided flows.

  The plurality of branch flows join the indoor air sucked from the pre-filter 311 and reach the HEPA filter 312 and the deodorizing element 313. The deodorizing effect is enhanced by the active species reaching the deodorizing element 313.

  The streamer discharge unit 340 includes a needle-like electrode made of tungsten, which is a positive electrode, and a plate-like electrode (counter electrode) that is located in the vicinity of the needle-like electrode and faces the electrode. By applying a high voltage to the needle-like electrode, streamer discharge, which is a kind of plasma discharge, is generated. Active species with high oxidative decomposition power are generated when the discharge is generated. These active species include fast electrons, ions, hydroxyl radicals, and excited oxygen molecules, and these active species are in the air consisting of small organic molecules such as ammonia, aldehydes, nitrogen oxides, etc. Decomposes harmful and odorous components.

  The generated air containing the active species flows into two vertical wind passage members 330 as shown in FIG. The first side suction port 111 and the second side suction port 112 of the air cleaner 100 are openings that are long in the vertical direction as described above, but the two vertical air passage members 330 are the first side suction port 111 and the second side suction port 111. It is arranged along the second side suction port 112. In each vertical wind passage member 330, a plurality of discharge ports 331 are formed along the vertical direction of the first side suction port 111 and the second side suction port 112. The air containing the active species that has flowed into the vertical wind passage member 330 is blown out from the discharge port 331 to the front of the prefilter 311 of the filter unit 310.

<Humidification part 320>
The humidifying unit 320 (humidity adjusting means) includes a humidifying rotor 321 and a water tray 322. The air that has passed through the deodorizing element 313 passes through the humidification rotor 321 of the humidification unit 320. When air passes through the humidification rotor 321, moisture is released from the humidification rotor 321 into the air. The humidification rotor 321 is supplied with water from the water tray 322 in order to compensate for moisture that is reduced by being discharged. Air containing active species is introduced into the water tray 322 from one of the discharge ports 331 provided in the vertical ventilation path member 330.

<Air cleaning operation>
The air cleaning action by the air cleaner 100 will be described with reference to FIG. The air sucked from the first side suction port 111 and the second side suction port 112 reaches the electric dust collector 200. Therefore, relatively large dust and dust are removed from the air by the prefilter provided outside the first casing portion 211 of the electrostatic precipitator 200. Next, the air passes through the discharge part of the electrostatic precipitator 200. At that time, dust or the like contained in the air is positively charged. Then, the air reaches the filter unit 310. On the other hand, the air sucked from the lower suction port 113 reaches the filter unit 310.

  In the filter unit 310, the air first passes through the prefilter 311. At that time, relatively large dust and dust are removed from the air by the pre-filter 311.

  The air that has passed through the prefilter 311 passes through the HEPA filter 312. The charged dust in the air is adsorbed by the HEPA filter 312.

  The air that has passed through the HEPA filter 312 passes through the deodorizing element 313 and is deodorized at this time.

  Thereafter, the air reaches the humidification rotor 321 of the humidification unit 320. The air passes through the humidification rotor 321 and is humidified.

  The air that has passed through the filter unit 310 and the humidification rotor 321 and has been purified is blown into the room from the air outlet 114. A part of the purified air is introduced into the streamer discharge unit 340 as a tributary 502 without being blown into the room.

  Active species are generated by the streamer discharge in the streamer discharge unit 340. The air containing the active species passes through the two vertical ventilation path members 330 and is discharged from the plurality of discharge ports 331 formed in each vertical ventilation path member 330 in front of the prefilter 311. The air containing the active species is mixed with the intake air and sucked into the prefilter 311 and the HEPA filter 312. Air containing these active species inactivates or kills viruses, fungi, bacteria, and the like.

<Sirocco fan 350>
The sirocco fan 350 (fan) is arrange | positioned between the suction inlet 110 and the blower outlet 114, and is arrange | positioned in more detail between the humidification part 320 and the blower outlet 114. FIG.

<Dust detection sensor 360>
The dust detection sensor 360 (dust detection means) is provided in the upper part in the air cleaner 100 and detects the amount of dust contained in the air around the air cleaner 100.

<Odor detection sensor 370>
The odor detection sensor 370 (odor detection means) is provided in the upper part in the air cleaner 100 and detects the odor intensity of the air around the air cleaner 100.

<Humidity detection sensor 380>
The humidity detection sensor 380 (humidity detection means) is provided in the upper part in the air cleaner 100 and detects the humidity of the air around the air cleaner 100.

<Operation unit 390>
FIG. 8 is a schematic diagram of the operation unit 390 of the air cleaner 100 shown in FIG. As shown in FIG. 8, the operation unit 390 includes an operation on / off switch 391, a humidification on / off switch 392, a humidification switching switch 393, an ECO power saving switch 394, and an air volume change switch 394.

  The operation on / off switch 391 is a switch for selecting operation or stop of the air purifier 100. When the air on / off switch 391 is pressed while the air purifier 100 is stopped, the air purifying operation is started. On the other hand, if the operation on / off switch 391 is pressed while the air cleaning operation is being performed, the operation is stopped.

  The humidification on / off switch 392 is a switch for selecting operation or stop of the humidification operation. When the humidification on / off switch 392 is pressed in a state where the air cleaning operation is performed and the humidification operation is not performed, the humidification rotor 321 is rotationally driven to start the humidification operation. At that time, a lamp indicating that the humidifying operation is being performed is turned on. On the other hand, when the humidification on / off switch 392 is pressed in a state where the humidification operation is performed together with the air cleaning operation, the rotation drive of the humidification rotor 321 is stopped and the humidification operation is stopped. At that time, the lamp is turned off. Even if the humidification on / off switch 392 is pressed to stop the humidification operation, the air cleaning operation continues.

  The humidification changeover switch 393 is a switch for switching a humidifying operation mode. The humidifying operation mode includes an automatic operation mode and a continuous operation mode. When the humidification switching switch 393 is pressed while the humidification operation is performed, these modes are switched under the control of the control unit 410.

  The automatic operation mode is a mode in which the air cleaner 100 automatically performs the operation or stop of the humidification operation with reference to the target humidity (for example, humidity 50%). Specifically, the humidity in the air detected by the humidity detection sensor 380 is compared with the target humidity, and the operation or stop of the humidification operation is determined, and the operation or stop of the humidification operation is executed based on the determination result. . On the other hand, the continuous operation mode is a mode in which the humidification operation is continued during the continuous operation mode.

  The ECO power saving switch 394 is a switch for selecting whether or not to execute an energy saving operation. As will be described later, when the air volume is set to automatic and the ECO power saving switch 394 is pressed, the mode is switched to the energy saving operation mode, and the lamp indicating the energy saving operation mode is turned on. On the other hand, when the ECO power saving switch 394 is pressed in the state where the energy saving operation is being executed, the energy saving operation mode is stopped, the state before switching to the energy saving operation mode is restored, and the lamp is turned off. When the air volume is set to automatic and the mode is switched to the energy saving operation mode, the maximum air volume in the automatic air volume operation is limited to an air volume smaller than the maximum air volume before switching to the energy saving operation mode.

  The air volume change switch is a switch for setting the air volume. When auto is set as the air volume, the air volume is automatically changed based on the amount of dust detected by the dust detection sensor 360 and the odor intensity detected by the odor detection sensor 370. Therefore, when the amount of dust detected by the dust detection sensor 360 or the odor intensity detected by the odor detection sensor 370 is large, the air volume is greatly changed, and the dust amount and odor detection sensor detected by the dust detection sensor 360 are changed. When the odor intensity detected at 370 is small, the air volume is changed to be small.

<Display unit 400>
The display unit 400 displays the amount of dust detected by the dust detection sensor 360, the odor intensity detected by the odor detection sensor 370, and the humidity detected by the humidity detection sensor 380. The display unit 400 is provided on the front panel 102 as shown in FIG. The amount of dust is displayed, for example, in three colors depending on the size. The odor intensity is displayed, for example, by lighting in three colors according to the strength. Humidity is displayed in increments of 1%, for example.

<Control unit 410>
FIG. 9 is a functional block diagram of the air purifier 100 shown in FIG. The control unit 410 includes a plurality of hardware such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory).

  The timer unit 411 determines whether or not the state in which the amount of dust detected by the dust detection sensor 360 is less than a predetermined amount has continued for a predetermined time, and the state in which the odor intensity detected by the odor detection sensor 370 is less than a predetermined strength. A timer for measuring each predetermined time when determining whether or not the time has continued and whether or not the state in which the humidity detected by the humidity detection sensor 380 is equal to or higher than the predetermined humidity has continued for a predetermined time is driven and controlled.

  In the energy saving operation mode when the humidifying operation is not performed in the air cleaner 100, the electric dust collector is based on the amount of dust detected by the dust detection sensor 360 and the odor intensity detected by the odor detection sensor 370. 200, the streamer discharge unit 340, the sirocco fan 350, etc. are controlled.

  In the air purifier 100, in the energy saving operation mode when the humidification operation is performed, the dust amount detected by the dust detection sensor 360, the odor intensity detected by the odor detection sensor 370, or the humidity detection sensor 380 is detected. The electrostatic precipitator 200, the streamer discharge unit 340, the sirocco fan 350, etc. are controlled based on the applied humidity.

  Hereinafter, the operation in the energy saving operation mode when the humidifying operation is performed will be described in detail.

  In the energy saving operation mode when the humidification operation is performed, the operation in any one of the first operation state, the second operation state, and the third operation state is performed.

  In the first operation state (with humidification operation), the electrostatic precipitator 200, the streamer discharge unit 340, and the humidification unit 320 are all in an operation state, and the sirocco fan 350 is driven based on the automatic air volume setting.

  In the second operation state (with humidification operation), the electrostatic precipitator 200 is stopped, the streamer discharge unit 340 and the humidification unit 320 are in operation, and the sirocco fan 350 is based on the automatic air volume setting. Driven.

  In the third operation state (with humidification operation), the electrostatic precipitator 200, the streamer discharge unit 340, and the humidifier 320 are all in a stopped state. In the third operation state (no humidification operation), the control unit 410 performs control so that the sirocco fan 350 is alternately driven or stopped.

In a state where the hinge 213 is closed, the ionization line 231 is located in a space formed by the casing second portion 212 and surrounds the middle wall 232b in a U shape. Further, the U-shaped ionization line 231 is surrounded by the left wall 232c and the right wall 232a from the outside. That is, the ionization line 231 is located between the left wall 232c and the middle wall 232b, and between the middle wall 232b and the right wall 232a, and in a state parallel to each wall, the ionization line 231 is appropriate for the wall and the discharge. Keep the distance of.

  When a high voltage is applied to the ionization line 231, a potential difference is generated between the two electrodes, and one kind of corona discharge is generated between the two electrodes at a portion where the ionization line 231 and the electrode plate 232 face each other. The part where the discharge occurs is called a discharge generation part.

  In the portion covering the discharge generating part (lattice part 200a), the casing first part 211 and the casing second part 212 are in a lattice shape. Further, the outer side of the lattice portion 200 a of the casing first portion 211 is covered with a pre-filter 219. The outer side of the lattice part 200a of the casing first part 211 corresponds to the upstream of the airflow of the sucked air. The sucked air enters the casing 210 from the lattice part 200a and passes through the discharge part. The dust in the air that passes through is charged by electric discharge.

<Filter unit 310>
As shown in FIG. 3, the filter unit 310 includes a pre-filter 311, a HEPA (High Efficiency Particulate Air Filter) filter 312 (dust collection filter), and a deodorizing element 313. First, large dust is removed by the pre-filter 311. Next, finer dust is removed by the HEPA filter 312. Further, the air that has passed through the HEPA filter 312 is decomposed or adsorbed by formaldehyde, odor components, and the like by a deodorizing element 313 containing activated carbon or the like.

<Streamer discharge unit 340>
A part of the air blown out from the sirocco fan 350 is sent to the streamer discharge unit 340 (active species supply means) as a tributary 502 shown in FIG. When this tributary 502 passes through the streamer discharge unit 340, the active species is supplied by the streamer discharge. The tributaries 502 supplied with the active species are blown out from the discharge port 331 to the front of the pre-filter 311 as a plurality of divided flows.

  The plurality of branch flows join the indoor air sucked from the pre-filter 311 and reach the HEPA filter 312 and the deodorizing element 313. The deodorizing effect is enhanced by the active species reaching the deodorizing element 313.

  The streamer discharge unit 340 includes a needle-like electrode made of tungsten, which is a positive electrode, and a plate-like electrode (counter electrode) that is located in the vicinity of the needle-like electrode and faces the electrode. By applying a high voltage to the needle-like electrode, streamer discharge, which is a kind of plasma discharge, is generated. Active species with high oxidative decomposition power are generated when the discharge is generated. These active species include fast electrons, ions, hydroxyl radicals, and excited oxygen molecules, and these active species are in the air consisting of small organic molecules such as ammonia, aldehydes, nitrogen oxides, etc. Decomposes harmful and odorous components.

  The generated air containing the active species flows into two vertical wind passage members 330 as shown in FIG. The first side suction port 111 and the second side suction port 112 of the air cleaner 100 are openings that are long in the vertical direction as described above, but the two vertical air passage members 330 are the first side suction port 111 and the second side suction port 111. It is arranged along the second side suction port 112. In each vertical wind passage member 330, a plurality of discharge ports 331 are formed along the vertical direction of the first side suction port 111 and the second side suction port 112. The air containing the active species that has flowed into the vertical wind passage member 330 is blown out from the discharge port 331 to the front of the prefilter 311 of the filter unit 310.

<Humidification unit 320>
The humidifying unit 320 (humidity adjusting means) includes a humidifying rotor 321 and a water tray 322. The air that has passed through the deodorizing element 313 passes through the humidification rotor 321 of the humidification unit 320. When air passes through the humidification rotor 321, moisture is released from the humidification rotor 321 into the air. The humidification rotor 321 is supplied with water from the water tray 322 in order to compensate for moisture that is reduced by being discharged. Air containing active species is introduced into the water tray 322 from one of the discharge ports 331 provided in the vertical ventilation path member 330.

<Air cleaning operation>
The air cleaning action by the air cleaner 100 will be described with reference to FIG. The air sucked from the first side suction port 111 and the second side suction port 112 reaches the electric dust collector 200. Therefore, relatively large dust and dust are removed from the air by the prefilter provided outside the first casing portion 211 of the electrostatic precipitator 200. Next, the air passes through the discharge part of the electrostatic precipitator 200. At that time, dust or the like contained in the air is positively charged. Then, the air reaches the filter unit 310. On the other hand, the air sucked from the lower suction port 113 reaches the filter unit 310.

  In the filter unit 310, the air first passes through the prefilter 311. At that time, relatively large dust and dust are removed from the air by the pre-filter 311.

  The air that has passed through the prefilter 311 passes through the HEPA filter 312. The charged dust in the air is adsorbed by the HEPA filter 312.

  The air that has passed through the HEPA filter 312 passes through the deodorizing element 313 and is deodorized at this time.

  Thereafter, the air reaches the humidification rotor 321 of the humidification unit 320. The air passes through the humidification rotor 321 and is humidified.

  The air that has passed through the filter unit 310 and the humidification rotor 321 and has been purified is blown into the room from the air outlet 114. A part of the purified air is introduced into the streamer discharge unit 340 as a tributary 502 without being blown into the room.

  Active species are generated by the streamer discharge in the streamer discharge unit 340. The air containing the active species passes through the two vertical ventilation path members 330 and is discharged from the plurality of discharge ports 331 formed in each vertical ventilation path member 330 in front of the prefilter 311. The air containing the active species is mixed with the intake air and sucked into the prefilter 311 and the HEPA filter 312. Air containing these active species inactivates or kills viruses, fungi, bacteria, and the like.

<Sirocco fan 350>
The sirocco fan 350 (fan) is arrange | positioned between the suction inlet 110 and the blower outlet 114, and is arrange | positioned in more detail between the humidification part 320 and the blower outlet 114. FIG.

<Dust detection sensor 360>
The dust detection sensor 360 (dust detection means) is provided in the upper part in the air cleaner 100 and detects the amount of dust contained in the air around the air cleaner 100.

<Odor detection sensor 370>
The odor detection sensor 370 (odor detection means) is provided in the upper part in the air cleaner 100 and detects the odor intensity of the air around the air cleaner 100.

<Humidity detection sensor 380>
The humidity detection sensor 380 (humidity detection means) is provided in the upper part in the air cleaner 100 and detects the humidity of the air around the air cleaner 100.

<Operation unit 390>
FIG. 8 is a schematic diagram of the operation unit 390 of the air cleaner 100 shown in FIG. As shown in FIG. 8, the operation unit 390 includes an operation on / off switch 391, a humidification on / off switch 392, a humidification switching switch 393, an ECO power saving switch 394, and an air volume change switch 394.

  The operation on / off switch 391 is a switch for selecting operation or stop of the air purifier 100. When the air on / off switch 391 is pressed while the air purifier 100 is stopped, the air purifying operation is started. On the other hand, if the operation on / off switch 391 is pressed while the air cleaning operation is being performed, the operation is stopped.

  The humidification on / off switch 392 is a switch for selecting operation or stop of the humidification operation. When the humidification on / off switch 392 is pressed in a state where the air cleaning operation is performed and the humidification operation is not performed, the humidification rotor 321 is rotationally driven to start the humidification operation. At that time, a lamp indicating that the humidifying operation is being performed is turned on. On the other hand, when the humidification on / off switch 392 is pressed in a state where the humidification operation is performed together with the air cleaning operation, the rotation drive of the humidification rotor 321 is stopped and the humidification operation is stopped. At that time, the lamp is turned off. Even if the humidification on / off switch 392 is pressed to stop the humidification operation, the air cleaning operation continues.

  The humidification changeover switch 393 is a switch for switching a humidifying operation mode. The humidifying operation mode includes an automatic operation mode and a continuous operation mode. When the humidification switching switch 393 is pressed while the humidification operation is performed, these modes are switched under the control of the control unit 410.

  The automatic operation mode is a mode in which the air cleaner 100 automatically performs the operation or stop of the humidification operation with reference to the target humidity (for example, humidity 50%). Specifically, the humidity in the air detected by the humidity detection sensor 380 is compared with the target humidity, and the operation or stop of the humidification operation is determined, and the operation or stop of the humidification operation is executed based on the determination result. . On the other hand, the continuous operation mode is a mode in which the humidification operation is continued during the continuous operation mode.

  The ECO power saving switch 394 is a switch for selecting whether or not to execute an energy saving operation. As will be described later, when the air volume is set to automatic and the ECO power saving switch 394 is pressed, the mode is switched to the energy saving operation mode, and the lamp indicating the energy saving operation mode is turned on. On the other hand, when the ECO power saving switch 394 is pressed in the state where the energy saving operation is being executed, the energy saving operation mode is stopped, the state before switching to the energy saving operation mode is restored, and the lamp is turned off. When the air volume is set to automatic and the mode is switched to the energy saving operation mode, the maximum air volume in the automatic air volume operation is limited to an air volume smaller than the maximum air volume before switching to the energy saving operation mode.

  The air volume change switch is a switch for setting the air volume. When auto is set as the air volume, the air volume is automatically changed based on the amount of dust detected by the dust detection sensor 360 and the odor intensity detected by the odor detection sensor 370. Therefore, when the amount of dust detected by the dust detection sensor 360 or the odor intensity detected by the odor detection sensor 370 is large, the air volume is greatly changed, and the dust amount and odor detection sensor detected by the dust detection sensor 360 are changed. When the odor intensity detected at 370 is small, the air volume is changed to be small.

<Display unit 400>
The display unit 400 displays the amount of dust detected by the dust detection sensor 360, the odor intensity detected by the odor detection sensor 370, and the humidity detected by the humidity detection sensor 380. The display unit 400 is provided on the front panel 102 as shown in FIG. The amount of dust is displayed, for example, in three colors depending on the size. The odor intensity is displayed, for example, by lighting in three colors according to the strength. Humidity is displayed in increments of 1%, for example.

<Control unit 410>
FIG. 9 is a functional block diagram of the air purifier 100 shown in FIG. The control unit 410 includes a plurality of hardware such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory).

A timer for measuring each predetermined time when determining whether or not the time has continued and whether or not the state in which the humidity detected by the humidity detection sensor 380 is equal to or higher than the predetermined humidity has continued for a predetermined time is driven and controlled.

  In the energy saving operation mode when the humidifying operation is not performed in the air cleaner 100, the electric dust collector is based on the amount of dust detected by the dust detection sensor 360 and the odor intensity detected by the odor detection sensor 370. 200, the streamer discharge unit 340, the sirocco fan 350, etc. are controlled.

[Features of the air conditioner of this embodiment]
The air conditioner of this embodiment has the following characteristics. In this air conditioner (air purifier 100), when both the electrostatic precipitator 200 and the streamer discharge unit 340 are in operation, when the amount of dust detected by the dust detection sensor 360 is less than a predetermined amount, When the electrostatic precipitator 200 is stopped and the amount of dust detected by the dust detection sensor 360 is less than a predetermined amount and the odor intensity detected by the odor detection sensor 370 is less than a predetermined intensity, Both the apparatus 200 and the streamer discharge unit 340 are changed to a stopped state. In this way, on the basis of detection by the dust detection sensor 360 and the odor detection sensor 370, the electrostatic dust collector 200 and the streamer discharge unit 340 that are not required to continue operation are stopped. Therefore, the power consumption of the air conditioner can be reduced.

  In addition, since the sirocco fan 350 is intermittently operated when both the electric dust collector 200 and the streamer discharge unit 340 are stopped, the detection accuracy of the dust detection sensor 360 and the odor detection sensor 370 can be improved. . Therefore, the operation of the electrostatic precipitator 200 and the streamer discharge unit 340 can be started when the amount of dust contained in the air is large or the odor intensity of the air is large in the third operation state.

  Further, when both the electrostatic precipitator 200 and the streamer discharge unit 340 are in a stopped state, when the odor intensity of the air changes greatly, the odor intensity of the air is reduced by operating the streamer discharge unit 340. be able to.

  Further, in this air conditioner, when both the electrostatic precipitator 200 and the streamer discharge unit 340 are in the stopped state, the electrostatic precipitator 200 and the streamer discharge unit are changed when the amount of dust contained in the air changes greatly. By operating 340, the amount of dust contained in the air can be reduced.

  Further, when the state where the amount of dust contained in the air is less than the predetermined amount continues for the first predetermined time, or when the state where the odor intensity of the air is less than the predetermined strength continues for the second predetermined time, the electrostatic precipitator Since the 200 and the streamer discharge unit 340 are stopped, it is possible to stop the electric dust collector 200 and the streamer discharge unit 340 that do not need to continue operation.

  Further, in consideration of not only the amount of dust contained in the air and the odor intensity of the air but also the humidity, both the electrostatic precipitator 200 and the streamer discharge unit 340 are changed to the stopped state.

  As mentioned above, although embodiment of this invention was described, it should be thought that the specific structure of this invention is not limited to the said embodiment. The scope of the present invention is shown not only by the description of the above-described embodiment but also by the scope of claims for patent, and further includes meanings equivalent to the scope of claims for patent and all modifications within the scope.

[Modification]
In the present embodiment, the air cleaner 100 includes the electric dust collector 200 and the streamer discharge unit 340. However, the air cleaner 100 has an odor removal and the like in addition to the electric dust collector 200 and the streamer discharge unit 340. There may be provided an ion generator for generating ions effective in the above.

  When the ion generating device is provided, the dust amount detected by the dust detection sensor 360 is a predetermined amount in the first operating state in which the electrostatic precipitator 200, the streamer discharge unit 340, and the ion generating device are all operating. In the case where the electric dust collector 200 is in a stopped state, the streamer discharge unit 340 and the ion generator are switched to the second operation state in which the electric dust collector 200 is in the operation state, and the dust amount detected by the dust detection sensor 360 is The third operation state in which the electrostatic precipitator 200, the streamer discharge unit 340, and the ion generator are all stopped when the odor intensity detected by the odor detection sensor 370 is less than the predetermined intensity. You may make it switch to.

  In the present embodiment, the sirocco fan 350 is intermittently operated in the third operation state, but the intermittent operation may not be performed.

  Moreover, in this embodiment, although switching of the 1st-3rd driving | running state is judged by whether it continued for the predetermined time, it is not essential to determine whether it continued for the predetermined time.

  In the present embodiment, the “dust collection filter” indicates the HEPA filter 312, but the “dust collection filter” may be the pre-filter 311, or the pre-filter 311 and the HEPA filter 312 are combined. A “dust collecting filter” may be used.

  In the present embodiment, the transition from the first operation state to the third operation state is described, but the transition from the second operation state to the third operation state is not described. However, in the second operation state, the transition from the second operation state to the third operation state may be performed as long as the condition for transition to the third operation state is satisfied. For example, in step S10 of FIG. 10 (second operating state), if the condition of step S10 is not satisfied, it is determined whether or not the condition of step S2 is satisfied, and if the condition of step S2 is satisfied, the process proceeds to step S3. It is also possible (shift to the third operating state).

  Further, in the present embodiment, when shifting from the third operation state to the first or second operation state, whether or not the amount of dust detected by the dust detection sensor 360 is a predetermined amount or more, the odor detection sensor 370. Whether or not the odor intensity detected in the above is equal to or higher than a predetermined intensity and whether or not the humidity detected by the humidity detection sensor 380 is lower than the predetermined humidity Although not seen, continuing for a predetermined time may be added to the transition condition.

  Further, in the present embodiment, whether or not the state where the amount of dust detected by the dust detection sensor 360 is less than a predetermined amount has continued for a predetermined time, and the odor intensity detected by the odor detection sensor 370 is less than the predetermined strength.
