The condensed water collected and collected is discharged to the outside through the drain pipe 37.

By these, the main air path which flows the air conditioner indoors is formed. That is, by operating the blower fan 311, indoor air is sucked in from the air intake port 27, heat-exchanged in the indoor heat exchanger 33 via the filter 231, and is taken out from the air blower outlet 29 into the room.

The ventilation device 32 is arranged in one side part of the indoor unit 2 as shown in FIG. Specifically, the ventilation device 32 is assembled to the side opposite to the blowing motor 313 for the blowing fan 311. The ventilator 32 has a ventilator suction port 325 at the top for sucking indoor air. The ventilator suction port 325 is located downstream of the filter 231, and the indoor air sucked from the upper air suction unit 230a is sucked through the filter 231.

The ventilator 32 has a ventilator supply / exhaust mechanism 327 in the rear part which exhausts indoor air to the outside and blows in fresh outdoor air. A ventilation air passage 39 is connected to the ventilation device supply / discharge mechanism 327, and the ventilation air passage 39 connects the pipe hole of the house with the connection pipe 8 connecting the indoor unit 2 and the outdoor unit 6. It penetrates and is taken out to the outside, and the front end of the ventilation air path 39 opens to the outside air, and the connection pipe 8 is connected to the outdoor unit 6.

Next, the air supply operation and the exhaust operation by the ventilation device 32 will be described with reference to FIGS. 5 and 6. FIG. 5 is a view schematically showing the flow of air in the ventilation device 32 shown in FIG. 2, and FIG. 6 is a view showing a state of operation of the ventilation device 32 shown in FIG.

The ventilation device 32 has two types of operation modes, the air supply operation and the exhaust operation, and the state of the operation stop. The flow direction of the wind and the opening / closing position of the damper in each operation mode are as shown in FIG. In addition, in the state of stoppage | operation, natural wind does not flow, but the suction switching damper 329-1 and the blowout switching damper 329-2 are in the respective positions b shown in FIG. 325 and the ventilating device outlet 326 prevent outdoor air from entering the room from the ventilator supply / exhaust 327.

In addition, although not specifically demonstrated, switching of each operation mode is performed by the operation part of a remote control, or is performed by the operation part of the indoor unit 2. As shown in FIG. In addition, it is also possible to switch the operation mode automatically in accordance with the surrounding environmental conditions, the operation progress of the air conditioner, etc. by a command from a control device (not shown).

The operation of the ventilation device 32 may be operated by the ventilation device 32 alone as long as the operation of the ventilation device 32 can be performed in combination with the air conditioning operation of the indoor unit 2. It is also possible to provide a timer to the ventilator 32 to automatically stop the operation after a certain time of operation.

By operating the suction switching damper 329-1, an exhaust suction air passage 328-5 for sucking indoor air from the ventilation device inlet 325, or an air supply suction air passage for sucking outdoor air from the ventilation device air supply / exhaust 327 ( 328-2) and the ventilation fan inlet 323 communicate with each other.

In addition, by operating the blow-out switching damper 329-2, the air is blown out from the air supply blow-out air passage 328-4, which blows air into the room from the ventilation device outlet 326, or the ventilation device supply / exhaust mechanism 327 to the outside. The air supply and exhaust passage 328-3 and the ventilation fan outlet 324 are communicated with each other.

In this way, the suction switching damper 329-1 and the blowout switching damper 329-2 are operated to switch the operation mode of the ventilation device 32 to either the air supply operation or the exhaust operation mode.

That is, in the air supply operation, since the suction switching damper 329-1 is on the side (b) shown in Fig. 5 and the air intake air passage 328-2 is opened by blocking the ventilation device inlet 325, the air supply suction air passage ( Outdoor air is sucked in through 328-2).

Next, in the exhaust operation, the intake switching damper 329-2 is on the side (a) shown in Fig. 5 and the ventilator suction inlet 325 is opened to block the air supply intake air passage 328-2. Although indoor air is sucked through 325, since the blowout switching damper 329-2 is on the (b) side, the air supply blowout air passage 328-4 is blocked, and the exhaust blowout air passage 328-1 is opened. As a result, the indoor air blown out through the ventilation fan outlet 324 flows into the exhaust blow-out air path 328-1, and passes through the air supply prefilter 327-1 to be exhausted from the ventilator supply / exhaust 327 to the outside.

At the time of stopping operation, both the suction switching damper 329-1 and the blowout switching damper 329-2 are on the side (b) shown in FIG. 5, and are provided through the air supply suction air passage 328-2, or the exhaust gas. The outdoor air is prevented from entering the room through the blowout air passage 328-1. Therefore, it is not necessary to provide a counterwind prevention valve for preventing the outdoor air from invading through the air supply / exhaust air passage at the time of stopping operation.

Doing.

The discharge electrode 402 is electrically connected to the high voltage side connection terminal 402a, and the discharge counter electrode 403 and the ground electrode 404 are both electrically connected to the ground side connection terminal 404a. A high voltage power supply (not shown) is connected to the high voltage side connection terminal 402a and the ground side connection terminal 404a, and the discharge counter electrode 403 and the ground electrode 404 are grounded to provide a negative high voltage to the discharge electrode 402. It is supposed to be authorized.

The mesh type ground electrode 404 is provided on the downstream side of the discharge electrode 402, the dielectric filter 405 is provided on the discharge electrode 402 side, and the ground electrode 404 of the dielectric filter 405 is provided. Dielectric polarization is positive on the negative side and positive on the discharge electrode 402 side.

Thereby, the dust in the airflow which the electron discharge | emitted from the discharge electrode 402 adheres and is negatively charged is attracted and captured by the positive polarization part of the dielectric filter 405. Since the electrostatic precipitating and hearing unit 40 is configured in this manner, fine dust having a particle diameter of about 0.01 μm can be efficiently collected. The dust-free air stream exits the mesh-shaped ground electrode 404 and enters the deodorizing filter 406, and the odor is removed to be clean, and flows out of the electric dust collection hearing unit 40. The discharge counter electrode 403 is an electrode for causing the emission of electrons from the discharge electrode 402 to protrude from the place of the dielectric filter 405 toward the discharge electrode 402.

The use of the dielectric filter 405 increases the amount of dust that can be held in the filter, and also, when cleaning the filter, charging is eliminated by washing with water, whereby dust can be easily removed.

Next, the dust sensor 158 used in the present embodiment will be described with reference to FIGS. 10 and 11. 10 is an explanatory diagram of the dust sensor 158 used for the indoor unit 1 in FIG. 1, and FIG. 11 is a scattered light receiving waveform diagram of the light receiving element 158j of the dust sensor 158 of FIG. 10.

In general, when light comes into contact with a colloidal solution, aerosol, or the like, it is known that light is scattered by the minute particles, and the light paths appear to shine likewise. This phenomenon is called a Tyndall phenomenon, and the phenomenon can be used to detect the presence of even fine particles invisible to the eye. In addition, since the intensity of the scattered light varies depending on the size of the particle when the incoming light is made constant, the approximate diameter of the particle can be known by observing the intensity of the scattered light.

In Fig. 10, the dust sensor collectively indicated by reference numeral 158 is an example of the dust sensor according to the above-described method, and has an inlet 158c of air to be measured under the shell 158a, The upper part has an outlet 158d of air to be measured. Inside the outer shell 158a, there is a measuring chamber 158e which communicates with the inlet 158c and the outlet 158d, and has a heater 158f in the vicinity of the inlet 158c in the measuring chamber 158e. Energizes 158f) to generate an upward airflow due to heating.

As a result, a flow of air under measurement from the inlet 158c toward the outlet 158d is generated, and the air under measurement passes through the measurement spot 158g of the measurement chamber 158e. The light to be passed through is irradiated with light from the light emitting diode 158h, and the scattered light generated by dust contained in the air to be measured is collected by the condensing lens 158i and received by the light receiving element 158j. Analyze the received data to measure the particle size and concentration of dust contained in the air under test.

At this time, the intensity of the scattered light is measured only for the dust passing through the narrow measurement spot 158g intersected by the condenser lens 158i. By shortening this and the measurement period sufficiently, most measurement cycles in which the number of dusts which pass through the measurement spot 158g become one or less in one measurement period are made. Of course, it is obvious that the measurement cycle, the input to the heater 158f, and the like are reduced to an appropriate value according to the concentration range of the target dust. This kind of technology is introduced in Japanese Patent Laid-Open No. 2-162238 and the like.

In general, the main dust of indoor dust is the cedar pollen that causes pollen, cypress pollen, house dust, which is the motive for seizures, as well as the dust, which is mostly dusty, and the smoke of cigarettes. It is mainly a smoke. These dusts are in the order of smoke <house dust ≒ pollen <dust, the approximate size of the smoke is 0.01 to 2 ㎛, house dust 0.8 to 100 ㎛, pollen 6 to 100 ㎛, especially the main cause of hay fever The size of cedar pollen, cypress pollen is 20 to 40 ㎛, dust is 100 ㎛ or more. Dust can be distinguished from the difference of these particle diameters, and it can process suitably.

The dust sensor used in the present embodiment is a dust having a relatively large particle size such as pollen, house dust, dust, etc. by using the intensity of scattered light being changed by the particle size of dust (hereinafter referred to as the upper diameter). Dust of relatively small particle sizes (hereinafter referred to as the particle diameter) can be identified. Furthermore, by providing a control device inside and supplying a 5 V DC power supply, the heater 158f and the light emitting diode 158h are energized, and the time difference of the intensity of scattered light of dust received by the light receiving element 158j is different. It also has a function of calculating and outputting the time (%) of detecting dust or more in diameter and the time (%) in detecting dust or more of lower diameter.

As a similar thing to such a sensor, the dust sensor PPD4NS made from Shin-Ai Co., Ltd. is mentioned, for example.

Next, the operation of the dust sensor 158 will be described with reference to FIG. FIG. 11A is a scattered light reception waveform diagram of the light receiving element 158j, and FIG. 11B is a pulse waveform diagram of negative logic when scattered light due to dust of a higher diameter or more is detected. Is a pulse waveform diagram of negative logic when the scattered light due to dust of a lower diameter or more is detected.

When dust with a large particle diameter such as pollen, house dust, dust, etc. passes through the measurement spot 158g, the intensity of light scattered by the dust is strong, and a large current flows through the light receiving element 158j. By setting an appropriate threshold value (il in FIG. 11 (a)), a pulse waveform of negative logic is shown in FIG. 11 when a large dust having a particle diameter such as pollen, house dust, dust, or the like passing through the measurement spot 158g. Can be output as shown in (b).

Similarly, when dust having a small particle size such as cigarette smoke passes through the measurement spot 158g, the intensity of light scattered by the dust is weak, and a small current flows through the light receiving element 158j. By setting an appropriate threshold value (Is in Fig. 11 (a)), a pulse waveform of negative logic is generated when the dust having a particle diameter of cigarette smoke or the like having a lower diameter or more passes through the measurement spot 158g. You can output it as well.

Scattered light is observed while one dust passes the measurement spot 158g, but as described above, the measurement spot 158g is narrowed to the condensing lens 158i, and the measured period is sufficiently 1 ms. Since the number of dusts passing through the measurement spot 158g is one or less in one measurement cycle, most of the measurements are made short, so that the particle size of the dust can be distinguished by the intensity of the scattered light, and pollen, house dust, Dust having a large particle size such as dust and dust having a small particle size such as cigarette smoke can be identified.

In this way, dust having a large particle size such as pollen, house dust or dust can be identified as a specific group having high intensity of scattered light from the dust in the room. In this case, in this embodiment, dust is identified by the intensity of scattered light of dust. However, in addition to this method, dust is identified by means of identifying and recognizing the shape of individual dusts, and the spatial distribution of scattered light by using a laser beam. Various methods, such as a recognition method, may be considered, but any method may be used to identify a specific group as long as sufficient reliability is secured according to the purpose.

In addition, the control device of the dust sensor 158 accumulates the time of the Lo output of FIG. 11 (b) for 1 second, and sets LdLoS as the time ratio (%) of detecting the dust of a large particle diameter more than upper diameter, and FIG. The time of Lo output of (c) is integrated for 1 second, and the time ratio (%) which detected the dust of the particle diameter more than a lower diameter is output as SdLoS. In this case, since the detection time of small particle size dust includes the detection time of big particle size dust, the correction time ratio SdAmS = SdLLoS-LdLoS is used instead of SdLoS to determine the density of small particle size dust.

Thirty (30) times of data of the time ratio (%) (LdLoS) and correction time ratio (SdAmS) for one second are accumulated in the storage unit of the control device, and the average of 30 times is average time ratio (LdLo) and correction average time ratio. The concentration is determined by comparing the data of (SdAm), the average time ratio SLdLo, and the modified average time ratio SSdAm, which the particle size distribution and the concentration have already been confirmed with known dust. Alternatively, the concentration is determined based on the correlation between this data and the count number of the fine particle counter confirmed in advance. In this way, dust having a large particle size such as pollen, house dust and dust, and dust having a small particle size such as cigarette smoke can be identified and its concentration can also be determined.

In addition, in the present embodiment, the concentration of dust is determined by integrating the scattered light intensity over a threshold value. However, as a method of determining the concentration of dust, a colorimetric equation and a measurement spot for comparing scattered light and standard light in addition to this method are used. Although various methods, such as a photometric formula for measuring the intensity of the scattered light and a counter formula for counting the scattered light of dust, can be considered, any method may be used as long as sufficient reliability is secured for the determination of the concentration.

Next, the dust removal operation | movement operation | movement of the air conditioner 1 using this dust sensor 158 is demonstrated using FIG. 12, FIG. 13, FIG. 14-16, FIG. 17-19. 12 and 13 are explanatory diagrams of a remote control function. 14 to 16 are flowcharts of main parts of the air conditioner operation control. 17-19 is a flowchart of the dust removal operation control main part.

For example, in a room where the air conditioner 1 is installed, if the occupant feels the pollen and recognizes the necessity of removing the pollen, the remote control 5 is directed toward the indoor unit 2 and the pollen button 53j is pressed. Alternatively, when the pollen comes to fly, the remote controller 5 instructs the indoor unit 2 to set the pollen monitoring function.

Moreover, since the setting of this pollen monitoring function is performed once per season, even if it is installed in the indoor unit main body, the convenience of a user is not impaired very much, and operation of the remote control 5 is simplified. In this case, the release of the pollen monitoring function is not necessary until the season off, and the automatic polling method may be performed for 90 days or more. For example, if the pollen monitoring function is set at the end of February, it may be automatically released at the beginning of June. .

The microcomputer, which is the control device of the indoor unit 2, monitors the presence or absence of the signal from the remote control 5 at a predetermined cycle as shown in FIG. 14 in step 15 (hereinafter referred to as step S15). If there is a signal, the process proceeds to S20 and after reading data from the remote control 5, the process proceeds to the determination of the presence or absence of a stop instruction signal of the air conditioner 1 of S25. If the data read out at S20 contains the stop instruction signal of the air conditioner 1, the process proceeds to S50, the various flags are turned off, the stop processing of the air conditioner 1 is performed at S60, and the remote control 5 Return to S15 to monitor the signal from. In this case, as mentioned later, the pollen monitoring flag and the pollution monitoring flag are not turned off, and are kept as the previous setting.

If there is no stop signal at S25, the flow advances to S30 to set various instruction flags on or off in accordance with the instruction signal from the remote control 5, and proceeds to S40 for various sensors such as indoor and outdoor temperature and humidity. Read data from If there is no signal from the remote control 5 in S15, the flow proceeds directly to S40 to continue the immediately preceding operation and reads data from the various sensors as described above. The setting of the various instruction flags in S30 and the data read in S40 proceed to S100 (see Fig. 15) via symbol (A) as basic data for air conditioner operation control, and subsequent control is performed.

In this case, various operations can be selected and instructed by the remote control 5, but among them, the air conditioner 1 is inevitably selected. In this embodiment, pollen monitoring and pollution monitoring have the same ventilation device. Control is included, so only one of the instructions can be given. Similarly, since the automatic operation instruction, the heating operation instruction, the dehumidification operation instruction, the cooling operation instruction, and the comfort operation instruction are also controlled by the same refrigeration cycle, only one instruction can be given. Alternatively, the air supply operation instruction and the exhaust operation instruction are also controlled by the same ventilation device, and therefore only one instruction can be given. In addition, since the wind speed automatic instruction, the wind speed instruction, the wind speed weak instruction, the wind speed instruction, and the wind direction instruction are controlled by the same blower, only one of these instructions can be given.

If the driving instruction from the remote control 5 is automatic driving in S100 shown in Fig. 15, the automatic driving instruction flag is turned on in S30, and it is determined in S100 to proceed to S105. In S105, the operating type of the air conditioner 1 is selected according to the indoor and outdoor temperature and humidity conditions, and if the selected type is heating in S115, the process proceeds to S145. The heating operation control is performed in S145, and the wind speed calculated by the heating operation control in S145 is set as the wind speed flag in S150, and the flow advances to S275.

If the selected category is not heating in S115 proceeds to S120, and if the selected category is dehumidified, proceeds to S175. The dehumidification operation control is performed in S175, and the wind speed calculated by the dehumidification operation control in S175 is set as the wind speed flag in S180, and the flow advances to S275.

If the selected type is not dehumidification in S120, the process proceeds to S125. If the selected type is cooling, the process proceeds to S205. The cooling operation control is performed in S205, and the wind speed calculated by the cooling operation control in S205 is set as the wind speed flag in S210, and the flow advances to S275.

If the selected type in S125 is not air-conditioned, the process proceeds to S260 via the symbol (D). If the instruction from the remote control 5 also instructs the air clean operation, the air clean operation instruction flag is turned on in S30, and it is determined in S260 and the flow advances to S265. The air clean driving control is performed at S265, and the wind speed calculated by the air clean driving control at S265 is set as the wind speed flag at S270, and the flow advances to S275.

If it is determined in S260 that the air clean driving instruction flag is turned off, the flow advances to S280, sets the wind speed flag to stop, sets the cycle hearing operation flag described later to off, and passes the symbol (C) to S330 (see FIG. 16). Proceed to

Next, the case returns to S100 and the case where the instruction from the remote control 5 is other than automatic operation will be described. If the instruction from the remote control 5 is heating operation, since the heating operation instruction flag is turned on at S30, the determination is made at S140, the process proceeds to S145 and the heating operation control is performed as described above, and the heating operation of S145 is performed. The wind speed calculated by the control is set as the wind speed flag in S150, and the flow advances to S275.

If the instruction from the remote control 5 is the dehumidification operation, since the dehumidification operation instruction flag is turned on in S30, it is determined in S170, the flow proceeds to S175, and the dehumidification operation control is performed as described above, and the dehumidification operation of S175. The wind speed calculated by the control is set as the wind speed flag in S180, and the flow advances to S275.

If the instruction from the remote control 5 is the cooling operation, since the cooling operation instruction flag is turned on in S30, it is determined in S200, the flow proceeds to S205, and the cooling operation control is performed as described above, and the cooling operation of S205 is performed. The wind speed calculated by the control is set as the wind speed flag in S210, and the flow advances to S275.

If the instruction from the remote control 5 is comfort driving, since the comfort driving instruction flag is turned on at S30, the determination is made at S230, the flow proceeds to S235, and the comfort driving control is performed, and the calculation is performed by the comfort driving control of S235. The set wind speed is set as the wind speed flag in S240, and the flow advances to S275.

This comfortable operation is a combination of a cooling operation and a dehumidification operation, and is an operation for the purpose of maintaining the ease of operation and comfort in the following operation by automatically setting the set temperature from the room temperature and the outdoor temperature.

Next, when the instruction from the remote control 5 instructs the air clean operation not involving the operation of the refrigeration cycle, the air clean operation instruction flag is turned on in S30, the automatic operation instruction, the heating operation instruction, the dehumidification operation instruction. Each flag of the cooling operation instruction and the comfortable operation instruction is turned off. S100, S140, S170, S200, S230, S260 determines this and proceeds to S265. Air clean operation control is performed as described above in S265, and the wind speed calculated by the air clean operation control in S265 is set as the wind speed flag in S150, and the flow advances to S275.

In S275, the cycle hearing operation flag indicating whether the control of the refrigeration cycle operation or the control of the air cleaning operation is performed is set to on, and the flow advances to S300 (see Fig. 16) via the symbol (B).

As shown in Fig. 16, when the instruction from the remote control 5 instructs the air clean operation accompanying the operation of the refrigeration cycle, the steps of any of S145, S175, S205, and S235 as described above. There is a case to reach S280 through. In this case, since it does not pass S265, the air cleaning operation | command instructed from the remote control 5 is not performed. In order to solve this problem, control proceeds to S330 by performing the same control as S260 and S265 in S300 and S305. In this case, since the wind speed flag is already set in S150, S180, S210, and S240, it is not necessary to set it again. If it is determined in S300 that the air clean driving instruction flag is OFF, the flow proceeds directly to S330.

Next, when the air supply operation is included in the instruction from the remote control 5, since the air supply operation instruction flag is turned on in S30, it is determined in S330, the flow proceeds to S335, and the air supply operation control is performed, and S340. The air supply driving flag is turned on at, the exhaust driving flag is turned off at S345, and the flow proceeds to S390.

If exhaust operation is included in the instruction from the remote control 5, the exhaust operation instruction flag is turned on in S30 and the air supply operation instruction flag is turned off. Therefore, it is determined in S330 and S360, and the flow proceeds to S365 to exhaust operation. Control is performed, the exhaust operation flag is turned on in S370, the air supply driving flag is turned off in S375, and the flow advances to S390.

When neither the air supply operation nor the exhaust operation is included in the instruction from the remote control 5, the air supply operation instruction flag and the exhaust operation instruction flag are all turned off in S30. Therefore, this is determined in S330 and S360, and the process proceeds to S380. In operation S380, the air supply driving flag is turned off in S380, and the exhaust driving flag is turned off in S385.

In this way, the power switch is turned on, but the state in which the electric dust collecting hearing unit, the blower, and the ventilator which are driven at the time of dust removal operation is stopped is made into the stopped state of the air conditioner, It also includes the operation waiting state by the on timer.

S390 is dust removal operation control of the lower program, and the dust removal operation control described next is performed. After performing the dust removal operation control in S390, the control returns to S15 via the symbol (E), monitors the instruction from the remote control 5, and controls the operation of the air conditioner 1 to control the comfort of the room. Continue to keep.

Next, the dust removal operation will be described with reference to FIGS. 17 to 21.

Dust removal operation is performed when the pollen monitoring or pollution prevention function is set by the remote control 5, and when the density of dust in the room is high, or when the pollen button 53j is pressed by the remote control 5. When the pollen button 53j is pressed by the remote control 5 or the pollen monitoring or pollution prevention function is set, the air conditioner operation control turns on the pollen button flag and / or the pollen monitoring flag or the pollution monitoring flag in S30, and the tactical As described above, the process proceeds to the dust removing operation control, which is a subprogram, in S390 through various steps. As a result, dust removal operation control, which is a subordinate program, is started in S400.

First, as shown in Fig. 17, when the pollen button flag is turned on in S405, the flow advances to S430 to check the presence or absence of energization of the dust sensor 158, and immediately starts the energization of the dust sensor 158 if it is not energized. In step S435, an interval of a predetermined time (1 minute) is set in order to secure a heating stability time of the heater 158f of the dust sensor 158 (S440). Next, it is checked in S445 whether the wind speed flag is set to stop. If the wind speed flag is set to stop, the blower 31 is operated in the positive mode which is the lowest wind speed (S450).

This is done to blow air in the room into the measurement chamber 158e of the dust sensor 158 prior to the start of use of the dust sensor 158, so as to secure a heating stable time of the heater 158f of the dust sensor 158. For one minute interval.

In this embodiment, this interval is set to 1 minute. However, since this interval is for the heating stabilization time of the heater 158f, an appropriate time needs to be determined by the type of the dust sensor 158. In addition, although the blower operation time at the time of starting the dust sensor 158 is made the same as the heating stabilization time of the heater 158f, since the interval different from this may be needed depending on the type of the dust sensor 158, it starts. It is necessary to confirm by

Next, the flow advances to S455 to store the current time at the time immediately before the blower stops (Ton), the flow advances to S460 to store the current time at the data reading time Tdt from the dust sensor 158, and the flow proceeds to S990. Return to the upper program.

When only pollen monitoring or pollution monitoring is set in the state in which there is no operation instruction from the remote control 5, if the amount of dust in the measurement chamber 158e of the dust sensor 158 is small, the blower 31 is turned off. The time not to drive continues. If such a state continues, the difference in the dust concentration of the air in the measurement chamber 158e of the dust sensor 158 and the indoor air will arise, and the dust sensor 158 will output incorrect data. To prevent this, the blower 31 is operated only for 20 seconds every 3 hours. This is because the time Ton immediately before the stop of the blower 31 is used later to measure this three-hour time interval.

The reason for storing the current time at the data read time Tdt will be described later.

In the embodiment, the stop time and the operation time are set to 3 hours and 20 seconds. However, since the appropriate value varies depending on the structure of the air conditioner 2 or the surrounding structure of the installation portion of the dust sensor 158, the starter or the like is used. You need to check.

If the wind speed flag is not set to stop in S445, the wind speed flag is set to any one of S150, S180, S210, S240, and S270. Therefore, the blower is operated at the set wind speed, and the process proceeds to S455 as described above. After the control, the host program is returned.

If there is energization from S430 to the dust sensor 158, the process proceeds to S465 and if one minute of the set interval S440 has not elapsed, the process proceeds to S445, and after the control as described above, the process returns to the higher level program.

After an interval of 1 minute has elapsed in S465, the flow advances to S470 to compare 1 second with the value obtained by subtracting the previous data reading time Tdt from the current time.

If the value obtained by subtracting the previous data reading time Tdt from the current time in S470 is less than 1 second, the flow advances to S530 to check the state of the cycle hearing operation flag.

If the value obtained by subtracting the previous data reading time Tdt from the current time in S470 is 1 second or more, the process proceeds to S480 to update the data reading time Tdt to the current time, and the process proceeds to S485 from the dust sensor 158. Read the data of the time ratio LdLoS (hereinafter referred to as the upper diameter time rate) that detects the dust above the upper diameter and the time rate SdLoS (hereinafter referred to as the lower diameter time rate) that detected the dust above the lower diameter .

Next, as described above, since the lower diameter time ratio SdLoS includes the upper diameter time ratio LdLoS, the modified lower diameter time ratio SdAmS = SdLoS-LdLoS is calculated in S490, and the flow proceeds to S495.

In S495, LdLoS and SdAmS data are stored in the N + 1st memory of the memory blocks LdM and SdM, and in S500, the average of the data in the memory blocks LdM and SdM is calculated, and the upper diameter average time ratio LdLo is calculated. Calculate the modified lower diameter average time ratio (SdAm).

Subsequently, 1 is added to N in S505. When N is less than 30 in S515, the flow advances to S530 to check the state of the cycle hearing operation flag. If N is greater than or equal to 30 in S515, the process proceeds to S520 where N is cleared to 0 and the process proceeds to S530.

If the cycle hearing operation flag is set to ON in S530 (S275), the flow advances to S540, and the computational wind speed flag FS0 is set equal to the current wind speed flag, and the flow proceeds to S800 via the symbol G.

This is because, in the dust removal operation, the wind speed of the blower 31 is used in preference to the wind speed set for cycle operation and air clean operation, and the indoor temperature and humidity are stabilized so as not to impair comfort.

If the cycle hearing operation flag is not turned on (S275) in S530, the process advances to S670 via the symbol (H).

In this embodiment, the upper diameter is 5 占 퐉 and the lower diameter is 1 占 퐉, and the dust removal operation can be performed for almost all pollen, dust, and large house dust, and the number of particles in the smoke of the cigarette is small. Only the components of 1 μm or more included must be detected to enable dust removal operation. Further, the target is condensed to cedar pollen and cypress pollen to have a top diameter of 10 µm, and only cedar pollen and cypress pollen can be grasped reliably, thereby reducing dust removal operation time, thereby avoiding unnecessary power usage. In addition, the dust identification method other than the particle size may be used together, and the lower diameter may be conveyed in the range of 0.01 to 1 µm, so that the dust removal operation can be reliably detected by the larger particle size of the cigarette smoke.

If the pollen button flag is off in S405, the flow advances to S410 to check the state of the pollen monitoring flag. If the pollen monitoring flag is on, the flow proceeds to S430 to perform the control as described above.

If the pollen monitoring flag is off in S410, the flow advances to S415 to check the state of the pollution monitoring flag. If the pollution monitoring flag is on, the flow proceeds to S430 to perform the control as described above.

If the pollution monitoring flag is off in S415, the flow advances to S418 to operate the blower at the wind speed set as the wind speed flag, and the flow proceeds to S420 to stop the power supply to the dust sensor to return to the upper program from S990.

Next, the procedure for determining the wind speed of the blower 31 from the upper diameter average time ratio LdLo and the crystal lower diameter average time ratio SdAm will be described with reference to FIGS. 18 and 20. 20 is a wind speed switching table of the dust group.

The present embodiment changes the wind speed of the blower 31 in accordance with the concentration of dust, increases the air velocity by increasing the wind speed when the dust concentration is high, increases the indoor air passing through the electric dust collecting hearing unit 40, and the electric dust collecting hearing unit The dust collection per unit time of (40) is increased to reduce the dust of the room quickly. For this reason, the time ratios A1 to D2 serving as threshold values of the wind speed switching as shown in Fig. 20 are determined so that the wind speed is switched to the appropriate dust concentration determined by the experiment in advance. These threshold values A1 to D2 are stored in a storage unit of the control device so that they can be referred to at any time from the control program.

First, the procedure for selecting the appropriate wind speed with respect to the density | concentration of dust with a large particle diameter more than an upper diameter is shown below. In the case of dust removal operation by pressing a pollen button or pollen monitoring, as described above, dust of a large particle size larger than the upper diameter may be largely monitored, and in the case of dust removal operation by pollution monitoring, a particle diameter larger than a lower diameter such as cigarette smoke, etc. It is necessary to greatly monitor both dust of house dust and dust of large particle size more than upper diameter such as house dust and dust.

As shown in Fig. 18, in S670, when the upper diameter average time ratio LdLo is smaller than C2 in the storage unit, the flow advances to S675; when the pollen button flag is on, the flow advances to S680, and it is determined from the upper diameter average time ratio. Proceed to S730 by setting one upper diameter wind speed FS2 to the positive mode.

When the pollen button flag is off in S675, the flow advances to S685. When the upper diameter average time ratio LdLo is smaller than the storage unit D2, the flow advances to S690 and determines the upper diameter wind speed FS2 determined from the upper diameter average time ratio. Set to stop mode and proceed to S730.

Next, the procedure for selecting the appropriate wind speed with respect to the dust of a small particle size below an upper diameter is shown below. In S730, when the crystal lower diameter average time ratio SdAm is smaller than C1 in the storage unit, proceed to S735; when the pollen button flag is on, proceed to S740; and the lower diameter wind speed (FS1 determined from the crystal lower diameter average time ratio. ), Go to S780 mode.

If the pollen button flag is off in S735, the flow advances to S745. If the crystal lower diameter average time ratio SdAm is smaller than D1 in the storage unit, the flow advances to S750, and the lower diameter wind speed determined from the crystal lower diameter average time ratio is determined. Proceed to S780 by setting FS1) to the stop mode.

When the pollen button flag is turned on in S780, the flow advances to S795, the calculation wind speed FS0 = the upper diameter wind speed FS2, and the flow proceeds to S800 (see Fig. 19) via the symbol G.

If the pollen button flag is off in S780, the flow advances to S785 to check the state of the pollen monitoring flag. If the pollen monitoring flag is turned on in S785, the flow advances to S795, and as described above, the flow advances to S800 with the computed wind speed FS0 = the upper diameter wind speed FS2.

If the pollen monitoring flag is off in S785, the flow advances to S790 to compare the upper diameter wind speed FS2 and the lower diameter wind speed FS1. If the upper diameter wind speed FS2 is faster than the lower diameter wind speed FS1 in S790, the flow advances to S795, and as described above, the flow advances to S800 with the operational wind speed FS0 = the upper diameter wind speed FS2.

If the lower diameter wind speed FS1 is faster than the upper diameter wind speed FS2 in S790, the flow advances to S797, and the flow advances to S800 with arithmetic wind speed FS0 = lower diameter wind speed FS1.

If the wind speed suitable for the removal of dust with a larger particle diameter or larger than the upper diameter does not coincide with the wind speed suitable for the removal of dust with a small particle size smaller than the upper diameter, the air velocity of the faster side is adopted to operate at the wind speed of the dust removal force. To do that.

In addition, if the time ratio of the calculation result is close to the threshold when driving in this manner, there is a fear that the operating wind speed of the blower is frequently switched by the variation of the measurement data. In such a case, it is desirable to secure the stability of the blower operation by providing hysteresis to the threshold for increasing the wind speed and the threshold for lowering the wind speed, or prohibiting other switching of the wind speed for a predetermined time after the wind speed is switched.

Next, operation control of the ventilation device 32 and the electric dust collecting process unit 40 at the time of dust removal operation is demonstrated using FIG.19, FIG.21. 21 is a dust group and a ventilation device operation table.

In operation S800 shown in FIG. 19, when the operational wind speed FS0 is in the stop mode, the flow advances to S805. When the current time is less than 3 hours from the time immediately before the blower stops, the flow advances to S807 to supply the air supply operation instruction flag or exhaust. Check the state of the operation instruction flag.

In step S825, the operation of the electrostatic precipitating process unit 40 is stopped, and the flow advances to S990 to return to the upper level program.

This is because, when only pollen monitoring or pollution monitoring is set as described above, the amount of dust in the indoor space indicated by the dust sensor 158 is small, and the upper diameter wind speed FS2 determined by the upper diameter average time ratio LdLo. ) Is in the stop mode and the lower diameter wind speed FS1 determined by the crystal lower diameter average time ratio SdAm is also in the stop mode, the time for which the blower 31 is not operated continues. If such a state continues, a difference in dust concentration between air in the measurement chamber 158e of the dust sensor 158 and indoor air is generated, and incorrect data of the dust sensor 158 is output. In order to prevent this, the blower 31 is operated only for 20 seconds every 3 hours. This is because the ventilation device 32, the blower 31, the upper and lower wind direction plates 291, the left and right wind direction plates 295, and the electrostatic precipitating process unit 40 are stopped during this three hour elapsed time.

If the air supply driving instruction flag and the exhaust driving instruction flag are turned off in S807, the flow advances to S810, the ventilator 32 is stopped, the flow advances to S815, the control as described above is performed, and the flow proceeds to S990, and the upper program. Return to,

If the current time has elapsed for three hours or more from the time immediately before the blower stop at Ton in S805, the flow advances to S840 to check the monitoring blower operation flag to be turned on at the time of blower operation for only 20 seconds every three hours described above. If the monitoring blower driving flag is turned off at S840, the process proceeds to S845 to operate the blower 31 in the normal mode, the process proceeds to S850 to turn on the monitoring blower driving flag to ON, and the process to S855 proceeds to the monitoring blower operating time of 20 seconds. Set, and the process proceeds to S990 to return to the upper level program.

When the monitoring blower driving flag is turned on in S840, the flow advances to S865. When the interval of the monitoring blower driving time has not elapsed, the flow proceeds to S990 as it is and returns to the upper level program.

If the interval of the monitoring blower operation time has elapsed in S865, the flow advances to S870, stores the current time at the time immediately before the blower stops (Ton), proceeds to S875, stops the operation of the blower 31, and proceeds to S880. The monitoring blower operation flag is turned off, and the flow advances to S990 to return to the upper level program.

When the pollen monitoring or pollution monitoring function is set by this control, even if the amount of dust in the room is small and the blower 31 is stopped, the dust sensor 158 is operated by driving the blower 31 for 20 seconds in 3 hours. The air in the measurement chamber 158e becomes almost the same as the room air, thereby increasing the reliability of the data from the dust sensor 158.

If the operational wind speed FS0 is other than the stop mode in S800, the flow advances to S900 to drive the blower 31 at the operational wind speed FS0, and the flow advances to S905 to store the current time at the time immediately before the blower stops (Ton) and update. Proceed to S910. If the air supply driving instruction flag or the exhaust driving instruction flag is turned on at S910, the flow proceeds to S980 to drive the electric dust collecting process unit 40, to remove dust in the room, and to restore the room to a clean state quickly, Proceed to S990 and return to the upper program.

If the air supply driving instruction flag and the exhaust driving instruction flag are turned off in S910, the flow advances to S920 to check the state of the pollen button flag. When the pollen button flag is turned on in S920, the flow proceeds to S955 to perform air supply operation to suck fresh outside air, and to remove dust such as pollen by using a high performance air supply hearing filter 327-2 installed in the air supply passage. Supply. In addition, the process proceeds to S980 to drive the electrostatic precipitating process unit 40, and the process proceeds to S990 to return to the upper level program.

If the pollen button flag is turned off in S920, the flow advances to S950 to check the state of the pollen monitoring flag. If the pollen monitoring flag is turned on in S950, the flow advances to S955 to control as described above, and the flow advances to S990 to return to the upper level program.

If the pollen monitoring flag is off in S950, the flow advances to S960 to check the state of the pollution monitoring flag. If the pollution monitoring flag is turned on in S960, the flow advances to S965 to perform an exhaust operation to discharge the contaminated indoor air to the outside, and proceeds to S980 to control as described above, and proceeds to S990 to return to the upper level program. .

If the pollution monitoring flag is off in S960, the flow advances to S980 to control as described above, and the flow advances to S990 to return to the upper level program.

Thus, the 1st output function which detects and outputs dust of 1 micrometer or more to a dust sensor, and the 2nd output function which detects and outputs dust of 5 micrometers or more are provided, and it is instruct | indicated and set according to this and the flying time of pollen By processing the pollen button and pollen monitoring function first, pollen in the room can be identified and pollen removal operation can be performed. In this case, if the pollen button and the pollen monitoring function are instructed and set, pollen removal operation is started even if large house dust or dust is detected. Ideally, since these are dusts generated indoors, it is efficient to operate the electric dust collection hearing unit, and in addition, to exhaust the ventilation device to reduce the dust in the room, but to operate the electric dust collection hearing unit even in the ash removal operation. Since the operation of the electric dust collection hearing unit becomes somewhat longer because the dust in the room is reduced by driving the air supply, the dust in the room is removed to be almost the same, so that there is almost no disadvantage for the user of the air conditioner.

In addition, in the present embodiment, the dust sensor was used by dividing the dust concentration by the particle size of two stages, but using the dividing dust concentration by the three stage particle diameters and outputting the pollen and dust with a particle diameter of 70 to 100 μm. It can also distinguish by identifying as a threshold. In this case, the pollen button of the embodiment is changed to a process button to stop pollen monitoring setting and integrate into the pollution monitoring setting. That is, when the operation of the electric dust collecting hearing unit is started by pressing the hearing button, when dust is identified as dust, when the dust is identified by pollen by exhausting the ventilation device, when the dust is identified as pollen, the ventilation device is supplied with air, and the dust is identified as smoke. If exhaust, ventilate the ventilation device. If more than two parts of dust, including pollen, are mixed, pollen should be given priority to operate the ventilation system. By doing in this way, operation suitable for the removal of the dust is performed in accordance with the classification of the dust in the room, thereby rapidly improving the indoor environment, and keeping the room in a state with little dust.

In addition, when the concentration of dust in the room is increased by setting the pollution monitoring, operation of the electric dust collecting hearing unit starts, when dust is identified as dust, when the dust is identified as pollen by exhausting the ventilation device. If the dust is identified as smoke by supplying air, the ventilation system is exhausted. If more than two parts of dust, including pollen, are mixed, pollen should be given priority to operate the ventilation system. By doing in this way, operation suitable for the removal of the dust is performed in accordance with the classification of the dust in the room, thereby rapidly improving the indoor environment, and keeping the room in a state with little dust.

In addition, although the present embodiment describes the removal of allergen dust such as cigarette smoke, pollen, house dust, dust, etc., the present invention is effective by confirming and applying the identification method for the removal of allergen-promoting substances. Of course it can be used.

As described above, according to the invention as set forth in claim 1, an electric dust collecting and hearing unit including a dielectric filter, a ventilator capable of supplying air to the outside air, and a suction path provided to the outside air by the ventilator are provided. A hearing filter and a dust sensor capable of identifying dust floating in the air are provided in the indoor unit, and when the dust sensor detects a specific group of dust including pollen, the operation of the electric dust collecting hearing unit and the ventilation A control device for controlling the air supply operation of the device is provided. As a result, when a large amount of dust is scattered outdoors and a large amount of dust is infiltrated indoors by ventilation required for indoor air regardless of natural ventilation or forced ventilation, this may cause an allergic reaction or a seizure. The dust sensor detects whether the dust is in a specific group containing pollen, which is a facilitating substance, and the concentration of dust. When the dust is dust in a specific group and the concentration is above a predetermined concentration, the electric dust collection hearing unit is operated. Dust is captured by a dielectric filter and removed. In addition, the outdoor device contained in the dust is removed by supplying air to the ventilation device, introducing the outside air, and passing the hearing filter installed in the suction path of the outside air. By supplying the outdoor air from which the outdoor dust has been removed from the ventilation device, natural ventilation from the gap between the houses is suppressed, and outdoor air including a large amount of outdoor dust is prevented from entering the room. In this way, an air conditioner which detects a specific dust containing pollen which is caused by an allergic reaction caused by an allergic reaction or a seizure-promoting substance, is damped and operated to obtain an air conditioner that keeps the room in a dust-free state. .

Moreover, according to invention of Claim 2, the said control apparatus is equipped with the monitoring function which monitors the presence or absence and the density | concentration of the said dust of the said specific group, even when operation stops, and the function which sets / cancels this monitoring function, This monitoring If the function is set, the dust sensor controls to perform the operation of the electric dust collecting hearing unit and the air supply operation of the ventilation device even when the dust sensor detects the dust of the specific group even when the operation is stopped. As a result, the monitoring function is set when it is predicted that the dust caused by the allergic reaction or the dust of the specific group that becomes the trigger substance of the seizure is filled outdoors, so that the amount of dust of the specific group scattered during the unknown Even if a large amount of dust of a certain group enters the room due to natural ventilation or the like, when the concentration of dust of a specific group in the room exceeds a predetermined value, the electric dust collection hearing unit automatically starts operation and dust of a specific group of the room. At the same time, by supplying the outside air from which the specific group of dust is removed from the ventilation device, it suppresses the outdoor air invading into the room by natural ventilation from the gap of the house, thereby reducing the supply of dust of the specific group into the room. Lower the concentration of dust in a particular group of rooms. In this way, it is possible to prevent the sudden occurrence of an allergy by a specific group of dust, and at the same time, it is not necessary to worry about the scattering state of the dust of a specific group at all times, thereby obtaining an air conditioner having a mental margin.

According to the invention described in claim 3, the indoor unit includes an electric dust collecting and hearing unit having a dielectric filter, a ventilator capable of supplying air to the outside air, and a hearing filter provided in a suction path of the outside air by the ventilator. And a function of instructing the remote control to remove dust of a specific group including pollen, the remote control having a remote control for controlling the operation, and operating the electric dust collection hearing unit by an instruction of removing the dust. And a control device for controlling the air supply operation of the ventilation device. People who are sensitive to dust of specific group often refrain from going out in fear of symptom deterioration while dust of specific group scatters, and time to spend indoors increases. In such a case, when the amount of dust of a specific group of outdoor groups has rapidly increased, and a large amount of dust of a certain group has invaded the room indoors by natural ventilation from gaps of houses, etc., a near remote control is felt. By instructing the air conditioner to remove the specific group of dust, the operation of the electrostatic precipitating hearing unit is started to capture and remove the specific group of dust with a dielectric filter. In addition, the ventilator starts the air supply operation to introduce outside air, and passes through the hearing filter installed in the intake path of the outside air to remove the specific group of dust contained therein. By supplying the outside air from which the specific group of dust is removed from the ventilation device, natural ventilation from the gap of the house is suppressed, and the concentration of dust of the specific group of the room is prevented by preventing the infiltration of outdoor air including a large amount of the specific group of dust into the room. Down. In this way, even when a dust-allergic seizure is about to occur, the electric dust collecting hearing unit is operated by instructing the vibration isolating operation while sitting or lying down from a nearby remote control without performing a large motion that is likely to be the motivation of the seizure. At the same time, it is possible to obtain an air conditioner for supplying air to the ventilation device to keep the room in a dust-free state.

In particular, a person with hay fever is concerned about worsening of symptoms at the time of pollen scattering and refrains from going out, and the time to spend indoors increases. When the amount of pollen in the outdoor skyrockets at such a time, a large amount of pollen infiltrates into a room by natural ventilation from the clearance gap of a house. At this time, when the precursor phenomenon of hay fever is sensed, an electric dust collection hearing unit is operated by instructing removal operation of pollen from a nearby remote control, and pollen is captured and removed by a hearing filter. In addition, the pollutant contained in the air is removed by introducing the outside air by supplying air to the ventilation device and passing through the hearing filter provided in the suction path of the outside air. By supplying the outside air from which the pollen is removed from the ventilation device, natural ventilation from the gap of the house is suppressed, and the outside air containing a large amount of pollen is prevented from entering the room. In this case, the air conditioner is provided with a dust sensor, and the dust that has invaded is a specific group of dust (for example, cedar pollen, cypress pollen) that causes seizure due to an allergic reaction, and its concentration is not less than a predetermined concentration. The dust sensor may be detected to control the pollen removal operation. In this way, a person suffering from symptoms can reliably collect pollen, which is an allergen of hay fever, to reliably collect and obtain an air conditioner that keeps the room in a dust-free state.

Further, according to the invention of claim 4, the function of instructing the dust removal is executed by pressing a dedicated button, so that the amount of dust of a specific group in the outdoor skyrockets, and the indoor ventilation is caused by natural ventilation from the gap between houses and the like. When a large amount of dust of a certain group is invaded and the precursor of an allergic attack is felt, the air conditioner can be instructed to remove a specific group of dust by simply pressing a dedicated button of a nearby remote control. As a result, the operation of the electrostatic precipitating hearing unit is started to capture and remove dust of a specific group with the dielectric filter, and the ventilator starts supplying air, introduces outside air, and passes through the hearing filter installed in the suction path of the outside air. This removes dust from certain groups that are included. By supplying the outside air from which the specific group of dust is removed from the ventilation device, natural ventilation from the gap of the house is suppressed, and the concentration of dust of the specific group of the room is prevented by preventing the inflow of outdoor air including a large amount of the specific group of dust into the room Down. In this way, even when a dust-allergen-like seizure is about to occur, the operation start of the electric dust collecting hearing unit and the air supply operation start of the ventilation device can be instructed by a simple operation without causing panic, thereby driving the electric dust collecting hearing unit. The air supply operation of the ventilation device is started to obtain an air conditioner that keeps the room in a dust-free state.

Further, according to the invention of claim 5, the dust sensor has a function of identifying at least three concentration ranges of dust, and the control device controls to switch the wind speed of the blower according to the identified concentration range. When large amounts of dust generated outdoors are scattered and a large amount of outdoor dust invades the room due to the ventilation required for indoor air regardless of natural or forced ventilation, this may cause allergic reactions or seizure-promoting substances. The dust sensor detects whether the dust is in a specific group and the concentration of dust. When dust is a specific group of dust and its concentration is above a predetermined concentration, the electrostatic precipitating hearing unit is operated and dust is captured by a dielectric filter to remove it. At this time, when the amount of dust in the room is small, the dust is gradually lowered while maintaining a quiet environment with low noise by operating the blower at low speed. If the amount of dust in the room is large, the noise in the room is somewhat increased, but increase the number of revolutions of the blower according to the concentration of dust, and operate the blower at a higher speed to increase the amount of room air passing through the electric dust collection hearing unit. Dust is collected at a rate, rapidly reducing the dust concentration in the room. In addition, the ventilation device is supplied with air to drive the outside air, and the outdoor dust included in the suction path of the outside air is passed through to remove the contained outdoor dust. By supplying the outdoor air from which the outdoor dust has been removed from the ventilation device, natural ventilation from the gap between the houses is suppressed, and outdoor air including a large amount of outdoor dust is prevented from entering the room. Thus, when there is much dust, it collects dust rapidly and reduces the dust density of a room in a short time, and when there is little dust, it can gradually reduce dust concentration by low noise operation, and can obtain the air conditioner which keeps indoors for a long time with little dust.

Further, according to the invention of claim 6, the ventilator also has an exhaust operation function, and the control apparatus supplies air supply or exhaust operation of the ventilator according to the group of dust identified by the dust sensor and the electric dust collection hearing. The operation of the unit is controlled. As mentioned above, the dust which floats in indoor air has the generation source outdoor and the generation source indoor. The operation method for reducing the indoor concentration of dust where the source is outdoors has been described in detail. When there is a large amount of dust indoors and out indoors, the dust sensor detects whether the dust belongs to one of a specific group causing seizure caused by an allergic reaction or a seizure promoting agent, and the concentration of dust. When the dust is dust belonging to one of the specific groups and its concentration is above a predetermined concentration, the electrostatic precipitating hearing unit is operated and the dust is captured by the dielectric filter and removed. Also, from the characteristics of the dust detected by the dust sensor, the control device identifies whether the dust is an outdoor source or an indoor source. If the dust is identified as an outdoor source, the ventilator is supplied with air supply to operate the outside air. And remove the outdoor dust contained by passing the hearing filter installed in the suction path of the outside air. By supplying the outdoor air from which the outdoor dust has been removed from the ventilation device, natural ventilation from the gap of the house is suppressed, and outdoor air including a large amount of outdoor dust is prevented from entering the room. In addition, when it is identified that dust is an indoor source, it is good to exhaust indoor air and introduce external air. In this case, by venting the ventilator and exhausting the indoor air to the outside, ventilation from the gap between the houses is promoted, and outside air with less dust is introduced into the room, thereby reducing the concentration of dust. In this manner, an air conditioner that improves the indoor environment quickly can be obtained by combining electric dust collecting operation with air supply operation (when the source is outdoor) or exhaust operation (when the source is indoor) according to the type of dust.

Further, according to the invention as set forth in claim 7, identification of the dust by the dust sensor is performed by identifying the size of the dust, and the control device causes the size of the identified dust to be larger than the first predetermined value and to be determined in advance. When it is smaller than 2 predetermined values, it controls so that air supply operation by the said ventilation apparatus may be performed, and in other cases, it controls so as to perform exhaust operation by the said ventilation apparatus. Commonly concerned indoor dust is mainly cedar pollen that causes pollen, cypress pollen, cotton dust that feels a lot of dust, and smoke that smokes mainly cigarettes. These can be distinguished by the size of the dust, and the size is smoke <pollen <dust. The magnitude | size of monitoring of the smoke and pollen which were separated in this way is made into the 1st predetermined value, and the magnitude | size of monitoring of pollen and dust is made into the 2nd predetermined value.

When the size of the dust in the room is between the first predetermined value and the second predetermined value, the dust is regarded as the main component of the pollen, and the electric dust collecting and hearing unit is operated to capture and remove the dust with a dielectric filter. In addition, the ventilation device is supplied with air to drive the outside air, and the outdoor dust included in the suction path of the outside air is passed through to remove the contained outdoor dust. By supplying the outdoor air from which the outdoor dust has been removed from the ventilation device, natural ventilation from the gap between the houses is suppressed, and outdoor air including a large amount of outdoor dust is prevented from entering the room. If the size of the dust in the room is smaller than the first predetermined value, or larger than the second predetermined value, the dust is regarded as smoke or dust as the main component, and the electric dust collection unit is driven to capture dust by the dielectric filter. Remove In addition, by venting the ventilation device to exhaust the indoor air to the outside, ventilation from the gap between the houses is promoted, and outside air with less dust is introduced into the room, thereby reducing the concentration of dust. In this way, it is possible to identify that the dust in the room is pollen, dust, or smoke, and to perform an operation suitable for removing the dust, thereby rapidly improving the indoor environment, thereby obtaining an air conditioner that keeps the room with less dust.

Further, according to the invention of claim 8, the first predetermined value is in the range of 5 µm to 10 µm and the second predetermined value is in the range of 70 µm to 100 µm, so that smoke, pollen, and dust are reliably protected. Classify and operate the dust appropriate to each dust treatment. If the size of the dust in the room is in the range of 10 μm to 70 μm including cedar pollen or cypress pollen, the dust is regarded as the main component of the dust, the dust collector is operated and the dust is captured by the dielectric filter. Remove In addition, the outdoor device is supplied with air to operate the ventilation device, and the outdoor dust included in the suction path of the outdoor air is passed through to remove the contained outdoor dust. By supplying the outdoor air from which the outdoor dust has been removed from the ventilation device, natural ventilation from the gap between the houses is suppressed, and outdoor air including a large amount of outdoor dust is prevented from entering the room. If the size of the dust in the room is smaller than 5 μm, or larger than 100 μm, the dust is regarded as smoke or dust as the main component, and the electrostatic precipitating hearing unit is operated and the dust is captured by the dielectric filter and removed. In addition, by venting the ventilation device to exhaust the indoor air to the outside, ventilation from the gap between the houses is promoted, and outside air with less dust is introduced into the room, thereby reducing the concentration of dust. As such, pollen in the indoor air is collected and allergens of hay fever are reduced from the indoor air to alleviate the symptoms of hay fever. In addition, it is possible to obtain an air conditioner that removes smoke and dust in the indoor air and keeps the room clean.

According to the invention described in claim 1, a specific dust including pollen that occurs outdoors and causes seizure due to an allergic reaction or becomes a seizure promoting substance is detected, and the dust is operated to keep the room in a dust-free state.

According to the invention of claim 2, it is possible to prevent the sudden occurrence of an allergy by a specific group of dust suddenly one day, and at the same time, there is no need to worry about the scattering state of the specific group of dust, thereby creating a mental margin.

According to the invention described in claim 3, even when a dust-allergic seizure is about to occur, the vibration suppression operation is instructed while sitting or lying down from a nearby remote control, without performing a large operation that is likely to be the motivation of the seizure. At the same time as the dust collecting hearing unit is operated, the ventilation device is supplied with air to keep the room in a dust-free state.

According to the invention as set forth in claim 4, even when a dust-allergen-like seizure is about to occur, the operation start of the electric dust collecting hearing unit and the air supply operation start of the ventilation device can be instructed by a simple operation without causing panic. The operation of the public hearing unit and the air supply operation of the ventilation device are started to keep the room in a dust-free state.

According to the invention of claim 5, when there is a lot of dust, dust is rapidly collected to reduce the dust concentration of the room in a short time, and when there is little dust, the dust concentration is gradually lowered by low noise operation to maintain the room for a long time with little dust.
