  Hereinafter, an embodiment of an air conditioner of the present invention will be described with reference to the drawings.

  First, the whole structure of an air conditioner is demonstrated using FIGS. 1 is a perspective view showing the configuration of an air conditioner according to an embodiment of the present invention, FIG. 2 is an explanatory diagram of the internal configuration of the indoor unit of FIG. 1 with the decorative panel removed, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. 4 is a perspective view for explaining opening and closing of the movable panel of the indoor unit of FIG.

  The air conditioner 1 is configured to connect the indoor unit 2 and the outdoor unit 6 with a connection pipe 8 so as to air-condition the room. The indoor unit 2 includes a casing 21 having an air suction port 27 at the upper portion and an air outlet port 28 at the lower portion, a movable panel 251 provided so as to open and close at least a part of the air suction port 27, Up and down airflow direction plate 291 provided to be able to turn up and down at the opening 28, left and right airflow direction plate 292 to be able to turn to the left and right at the air blowing port 28, and indoor air is sucked from the air suction port 27 and is blown out. The blower 31 installed in the housing 21 so as to blow out from the fan 21, the blower motor 313 that drives the blower 31, the indoor heat exchanger 33 provided on the suction side of the blower 31, and the air suction port 27. And an indoor dust exchanger 40 provided with an electric dust collection and air cleaning unit 40.

  The indoor unit 2 has a configuration in which an indoor heat exchanger 33, a blower fan 311, a dew tray 35, and the like are attached to a housing 21, covered with a decorative frame 23, and a front panel 25 is attached to the front surface of the decorative frame 23. The decorative frame 23 is provided with an air inlet 27 for sucking indoor air and an air outlet 29 for blowing air in which temperature and humidity are harmonized.

  In addition, a display unit 397 for displaying an operation status and a light receiving unit 396 for receiving an infrared operation signal from a separate remote controller 5 are arranged at the lower center of the front panel 25.

  Basic internal structures such as a blower fan 311, a filter 231, an indoor heat exchanger 33, a dew tray 35, an up / down wind direction plate 291, and a left / right wind direction plate 295 are attached to the housing 21. And basic internal structures, such as the ventilation fan 311 attached inside the housing | casing 21, are included in the indoor unit 2 by attaching the decorative frame 23. FIG. The decorative frame 23 forms attachment ribs on both sides of the upper part, scratches the attachment ribs to the front part of the casing 21, and attaches the lower part to the casing 21 with screws or the like.

  An air outlet 29 formed on the lower surface of the decorative frame 23 is disposed adjacent to the divided portion with the front panel 25 and communicates with the rear outlet air passage 290. The up-and-down wind direction plate 291 substantially conceals the blowing air passage 290 in the closed state, and forms a continuous large curved surface on the bottom surface of the indoor unit 2. The up / down wind direction plate 291 is pivoted at a required angle when the air conditioner is operated by a drive motor (not shown) in response to an instruction from the remote controller 5 with pivot shafts provided at both ends as fulcrums. 29 is opened and the state is maintained. When the operation of the air conditioner is stopped, the air outlet 29 is controlled to be closed.

  The left and right wind direction plates 295 are configured to be rotatable by a drive motor (not shown) with a rotation shaft provided at the lower end as a fulcrum, and are rotated in accordance with an instruction from the remote controller 5 to maintain the state. Blowing air is blown out in the desired direction on the left and right. By instructing from the remote controller 5, the up and down wind direction plate 291 and the left and right wind direction plate 295 can be periodically oscillated during the operation of the air conditioner, and the blown air can be periodically sent over a wide range in the room.

  In addition, the movable panel 251 attached to the front panel 25 is configured to be rotatable about a rotation shaft provided at the lower end portion by rotating a drive motor (not shown), and the front air suction is performed during the operation of the air conditioner. The unit 230b is opened, indoor air is also sucked into the indoor unit from the front air suction unit 230b, and the front air suction unit 230b is closed when the air conditioner is stopped.

  And according to the indoor unit 2 which concerns on a present Example, at the time of a stop, the air blowing wind path 290 and the front side air suction part 230b are concealed with the up-and-down wind direction board 291 and the movable panel 251, and are matched with interior. During operation, the up / down wind direction plate 291 and the left / right wind direction plate 295 are rotated in accordance with an instruction from the remote controller 5. At the same time, the movable panel 251 is opened to suck indoor air from the front air suction portion 230b and the upper air suction portion 230a. The sucked indoor air can be blown out from the air outlet 29 as cold air or hot air by the internal indoor heat exchanger 33.

  When the air conditioner 1 is operated, it is connected to a power source (not shown) and the remote controller 5 is operated to perform desired operations such as heating, dehumidification, and cooling.

  A case of operation such as cooling will be described with reference to FIGS. In the case of operation such as cooling, in order to pass room air through the indoor heat exchanger 33 in the front part of the blower 31, the movable panel 251 constituting a part of the front panel 25 is rotated and opened as shown in FIG. The indoor air is circulated to the indoor heat exchanger 33 through the upper air suction portion 230a and the front air suction portion 230b of the decorative frame 23 at the back of the opened movable panel 251.

  The indoor unit 2 includes a control board in an electrical component box (not shown) inside, and a microcomputer is provided on the control board. The microcomputer receives signals from various sensors such as an indoor temperature sensor and an indoor humidity sensor (not shown), receives an operation signal from the remote controller 5 at the light receiving unit 396, and also drives the indoor blower 31, a movable panel drive motor, and a vertical wind direction plate drive. The indoor unit 2 is controlled in an integrated manner, such as controlling the motor, the left and right wind direction plate drive motors, and controlling communication with the outdoor unit.

  As shown in FIG. 3, the indoor unit 2 is in a state in which the movable panel 251 and the vertical wind direction plate 291 are closed, as shown in FIG. 3. In this state, when a driving operation signal is made from the remote controller 5, a microcomputer (not shown) can perform cooling or heating based on information from various sensors if an operation signal from the remote controller 5 or automatic operation is set. Determine the operation mode. Based on this determination, the movable panel 251 and the up / down wind direction plate 291 are operated to open the airflow passage. At this time, the air inlet 230b is opened, but the line of sight from the room is blocked by the movable panel 251 and does not reach the interior of the indoor unit 2, and the atmosphere of the interior is not destroyed.

  That is, the microcomputer operates a drive motor (not shown) to rotate the up / down wind direction plate 291 and the left / right wind direction plate 295 to the blowing angle corresponding to the instruction from the remote controller 5. Further, the microcomputer operates a movable panel drive motor that opens the movable panel 251 in conjunction with the operation of the up / down wind direction plate 291.

  Next, the microcomputer rotates the indoor blower 31 and sucks indoor air from the upper and front air suction portions 230a and 230b. Control is performed so that the sucked indoor air is blown out from the air outlet 29 along the up-and-down air direction plate 291 and the left-and-right air direction plate 295 without hot or cold air or heat exchange by the indoor heat exchanger 33. On the other hand, when stopping the operation, after the indoor blower 31 is stopped, the drive motor of the movable panel 251 and the drive motor of the up-and-down air direction plate 291 are reversely rotated. In this way, control is performed to return from the open state to the closed state.

  The filter 231 is disposed so as to cover the suction side of the indoor heat exchanger 33, and removes dust contained in the sucked indoor air. The blower fan 311 is a horizontally long cross-flow fan, and is arranged in the center of the indoor unit 2 so as to suck indoor air from the air suction port 27 and blow it out from the air blowout port 29. The indoor heat exchanger 33 is disposed on the suction side of the blower fan 311 and is formed in a substantially inverted V shape so as to surround the top and front of the blower fan 311.

  The dew receiving tray 35 is disposed below the lower ends of the front and rear sides of the indoor heat exchanger 33, and is provided for receiving condensed water generated in the indoor heat exchanger 33 during cooling operation or dehumidifying operation. The condensed water received and collected is discharged to the outside through the drain pipe 37. As a result, a main air passage is formed to flow indoor air to be conditioned. That is, by operating the blower fan 311, the indoor air is sucked from the air suction port 27, is heat-exchanged by the indoor heat exchanger 33 through the filter 231, and then blown into the room from the air blowing port 29. .

  The ventilation device 32 is arranged on one side of the indoor unit 2. Specifically, the ventilation device 32 is incorporated on the side opposite to the blower motor 313 for the blower fan 311. The ventilator 32 has a ventilator inlet 325 for sucking room air at the top. The ventilation device suction port 325 is located on the downstream side of the filter 231, and the indoor air sucked from the upper air suction portion 230 a is sucked through the filter 231.

  The ventilator 32 has a ventilator supply / exhaust port 327 at the rear for exhausting indoor air to the outside and taking in fresh outdoor air. A ventilation air passage 39 is connected to the ventilating air supply / exhaust port 327, and this ventilation air passage 39 passes through a piping hole of the house together with a connection pipe 8 connecting the indoor unit 2 and the outdoor unit 6 to the outside. The tip of the ventilation air passage 39 is drawn out to the outside air, and the connection pipe 8 is connected to the outdoor unit 6.

  The ventilation device 32 has two types of operation modes, ie, an air supply operation and an exhaust operation, and an operation stop state.

  Further, although not specifically described, the switching of each operation mode is performed by the operation unit of the remote controller or the operation unit of the indoor unit 2. In addition, the operation mode can be automatically switched according to the surrounding environmental conditions, the operation of the air conditioner, and the like by a command from a control device (not shown).

  The ventilation device 32 can be operated in combination with the cooling / heating operation of the indoor unit 2 or can be operated by the ventilation device 32 alone. Furthermore, it is possible to automatically stop the operation after providing a timer in the ventilation device 32 and operating for a certain period of time.

  The ventilator 32 operates a switching damper (not shown) to discharge the indoor air sucked from the ventilator suction port 325 to the ventilator supply / exhaust port 327 and exhaust it to the outside air, and from the ventilator supply / exhaust port 327. It is possible to switch between an air supply operation in which the sucked outdoor air is discharged to the ventilator outlet 326 and blown into the room to supply air.

  In this way, the operation mode of the ventilation device 32 is switched to either the air supply operation mode or the exhaust operation mode by operating the suction switching damper 329-1 and the blowout switching damper 329-2.

  That is, in the air supply operation, since the suction switching damper is on the second side, the ventilator suction port is shut off and the supply air suction air passage is opened, so that outdoor air is sucked through the air supply suction air passage. At this time, since the blowout switching damper is on the first side, the air supply blowout air passage is opened and the exhaust blowout air passage is blocked, so that the outdoor air blown to the ventilation fan blowout port is blown into the air supply blowout air passage. The

The blown outdoor air is blown into the indoor unit from the ventilator blowout port 326. And in the case of a present Example, the outdoor air inhaled by the ventilation fan 321 is inhaled from the ventilator supply / exhaust port 327,
In the air supply operation, the sucked outside air is blown out into the room through an air supply prefilter and an air supply air filter provided in the air supply path. First, after dust contained in the air is removed on the surface of the air supply prefilter, dust having a particle size of 10 μm or more can be collected with high efficiency close to 99.9%, and further, a deodorizing function. The fine dust and odor contained in the air are removed by passing through the air supply and cleaning filter, which is also cleaned and blown out indoors.

  The electric dust collection and cleaning unit 40 faces the upper air suction portion 230a even in a state where the movable panel 1 is closed between the pre-filter 231 and the indoor heat exchanger 33 in the air flow flowing through the interior of the indoor unit 2. In the frame, a needle-like discharge electrode, a strip-like discharge counter electrode, a dielectric filter having a honeycomb-like lattice, a net-like ground electrode, and a deodorizing filter are incorporated.

  By using a dielectric filter, the amount of dust that can be held in the filter increases, and when cleaning the filter, washing is performed with water, and the charge is removed so that the dust can be easily detached.

  The dust sensor 158 detects indoor dust and outputs information on its concentration to the control unit of the air conditioner 1. The human detection sensor 159 transmits information resulting from the infrared rays emitted by the occupants, movements of the occupants, voices, and the like to the control unit, and the control unit analyzes the information by various methods. Determine if there are people in the room. In addition, since it may be considered that the control of the air conditioner 1 by the human detection sensor 159 becomes inappropriate, the remote controller 5 can instruct whether the human detection sensor 159 is enabled or disabled.

  Next, the dust removal operation of the air conditioner 1 using the dust sensor 158 will be described with reference to FIGS. 5, 6, 7 to 9, and FIGS. 10 to 12. 5 and 6 are explanatory diagrams of the remote control function. FIG. 7 to FIG. 9 are main parts of the air conditioner operation control flow. 10 to 12 show the main flow of the dust removal operation control.

  For example, in a room where the air conditioner 1 is installed, when the resident feels the pollen sign and recognizes the necessity of removing pollen, the remote controller 5 is pointed at the indoor unit 2 and the pollen button 53j is pressed. Alternatively, when it is time for the pollen to fly, the indoor unit 2 is instructed from the remote controller 5 by the watch selection button 55k for setting the pollen watch function.

  Since the setting of the pollen look-out function is performed once per season, even if it is provided at an appropriate position of the indoor unit main body, the convenience of the user is not significantly impaired, and the operation of the remote controller is simplified. In this case, the release of the pollen watch function is not required until the season is off, and an automatic release method of 90 days or more may be used. For example, if the pollen watch function is set at the end of February, it may be automatically released at the beginning of June.

  The control device (not shown) of the indoor unit 2 monitors the presence / absence of a signal from the remote controller 5 in a predetermined cycle in step 15 (hereinafter step is abbreviated as S15), and if there is a signal, Proceeding to S20, the data from the remote controller 5 is read, and the process proceeds to S25. If the data read in S25 includes a stop instruction signal for the air conditioner 1, the process proceeds to S50 to turn off various flags, stop the air conditioner 1 in S60, and monitor the signal from the remote controller 5. Therefore, the process returns to S15. In this case, the pollen lookout flag, the dirt lookout flag, and the human sensor invalid instruction flag are not turned off and are maintained as they were immediately before.

  If there is no stop signal in S25, the process proceeds to S30 and various instruction flags are set to ON or OFF according to the instruction signal from the remote controller 5, and the process proceeds to S40 to read data from various sensors such as the indoor / outdoor temperature and humidity. Include. If there is no signal from the remote controller 5 in S15, the process proceeds directly to S40 in order to continue the previous operation, and data from various sensors is read as described above. Various instruction flags are set in S30, and the data read in S40 is used as basic data for air conditioner operation control to proceed to S100 via the symbol (A) and subsequent control is performed.

  In this case, the remote controller 5 can select and instruct various types of operation, but some of them must be selected because of the configuration of the air conditioner 1. In this embodiment, pollen watching and dirt are present. Since the lookout includes control of the same ventilator, only one of the instructions can be given. Similarly, the automatic operation instruction, the heating operation instruction, the dehumidifying operation instruction, the cooling operation instruction, and the cool operation instruction are also the same refrigeration cycle control, and therefore only one of these instructions can be given. Similarly, since the air supply operation instruction and the exhaust operation instruction are the same ventilation device control, only one of the instructions can be given. Similarly, the wind speed automatic instruction, the wind speed strong instruction, the wind speed weak instruction, the wind speed fine instruction, and the wind speed static instruction are the same blower control, and therefore only one of these instructions can be given.

  If the operation instruction from the remote controller 5 is automatic operation in S100, the automatic operation instruction flag is turned on in S30, so this is determined in S100 and the process proceeds to S105. In S105, the operation type of the air conditioner 1 is selected according to the indoor and outdoor temperature and humidity conditions. If the selection type is heating in S115, the process proceeds to S145. The heating operation control is performed in S145, the wind speed calculated by the heating operation control in S145 is set in the wind speed flag in S150, the process proceeds to S245, the movable panel flag is set to open, the vertical wind direction plate 291 and the left and right wind directions in S250 and S255. The plate 295 is stopped or rocked according to the up / down wind direction plate instruction flag and the left / right wind direction plate instruction flag from the remote controller, and the process proceeds to S275.

  If the selection type is not heating in S115, the process proceeds to S120, and if the selection type is dehumidification, the process proceeds to S175. The dehumidifying operation control is performed in S175, the wind speed calculated by the dehumidifying operation control in S175 is set in the wind speed flag in S180, the process proceeds to S245, the same control as described above is performed in S250, S255, and the process proceeds to S275.

  If the selection type is not dehumidifying in S120, the process proceeds to S125, and if the selection type is cooling, the process proceeds to S205. Cooling operation control is performed in S205, the wind speed calculated by the cooling operation control in S205 is set in the wind speed flag in S210, the process proceeds to S245, the same control as described above is performed in S250, S255, and the process proceeds to S275.

  If the selection type is not cooling in S125, the process proceeds to S260 via the symbol (D). Here, if the instruction from the remote controller 5 also instructs the air cleaning operation, the air cleaning operation instruction flag is turned on in S30, so this is determined in S260 and the process proceeds to S265. Air cleaning operation control is performed in S265, the wind speed calculated by the air cleaning operation control in S265 is set in the wind speed flag in S270, the process proceeds to S272, the movable panel flag is closed, and the same control as described above is performed in S250 and S255. And proceed to S275.

  If it is determined in S260 that the air cleaning operation instruction flag is off, the process proceeds to S280, the wind speed flag is set to stop, the process proceeds to S281, the movable panel flag is set to closed, and the vertical wind direction plate and the left and right wind direction plate are set in S282, S283. , The process proceeds to S285, a cycle emptying operation flag described later is set to OFF, and the process proceeds to S330 via the symbol (C).

  Next, returning to S100, the case where the instruction from the remote controller 5 is other than the automatic operation will be described. If the instruction from the remote controller 5 is the heating operation, the heating operation instruction flag is turned on in S30, so this is determined in S140, the process proceeds to S145, the control is performed as described above, and the process proceeds to S275.

  Similarly, when the instruction from the remote controller 5 is the dehumidifying operation, the cooling operation, or the cool operation, this is determined in S170, S200, and S230, the process proceeds to S175, S205, and S235, and the control is performed as described above, and the process proceeds to S275.

  Here, the cool operation is an operation in which the cooling operation and the dehumidification operation are combined, and the operation is performed for the purpose of maintaining the convenience and comfort of operation in the summer by automatically setting the set temperature from the room temperature and the outdoor temperature.

  Next, when the instruction from the remote controller 5 indicates an air cleaning operation that does not involve the operation of the refrigeration cycle, the air cleaning operation instruction flag is turned on in S30, an automatic operation instruction, a heating operation instruction, a dehumidifying operation instruction, a cooling operation The driving instruction and cool driving instruction flags are off. This is determined in S100, S140, S170, S200, S230, and S260, and the process proceeds to S265. As described above, the process proceeds to S275 through S270, S272, S250, and S255.

  In S275, the cycle emptying operation flag indicating whether the control of the refrigerating cycle operation or the control of the air cleaning operation is performed is set to ON, and the process proceeds to S300 via the symbol (B).

  When the instruction from the remote controller 5 instructs the air cleaning operation accompanied by the operation of the refrigeration cycle, the process may reach S275 through any of the steps S145, S175, S205, and S235 as described above. In this case, since S265 is not passed, the air cleaning operation instructed from the remote controller 5 is not performed. In order to eliminate this problem, the same control as S260 and S265 is performed in S300 and S305, and the process proceeds to S330. In this case, since the wind speed flag has already been set in S150, S180, S210, and S240, it is not necessary to set it again. If it is determined in S300 that the air cleaning operation instruction flag is off, the process proceeds directly to S330.

  Next, when the air supply operation is included in the instruction from the remote controller 5, since the air supply operation instruction flag is turned on in S30, this is determined in S330, and the process proceeds to S335 to perform the air supply operation control. In step S340, the air supply operation flag is turned on. In step S345, the exhaust operation flag is turned off, and the process proceeds to step S390.

  If the instruction from the remote controller 5 includes the exhaust operation, the exhaust operation instruction flag is turned on and the air supply operation instruction flag is turned off in S30, so this is determined in S330 and S360, and the process proceeds to S365. Advance exhaust operation control is performed, the exhaust operation flag is turned on in S370, the air supply operation flag is turned off in S375, and the process proceeds to S390.

  If neither the air supply operation nor the exhaust operation is included in the instruction from the remote controller 5, both the air supply operation instruction flag and the exhaust operation instruction flag are turned off in S30, so this is determined in S330 and S360. The process proceeds to S380, the air supply operation flag is turned off in S380, the exhaust operation flag is turned off in S385, and the process proceeds to S390.

  As described above, the air conditioner is in a state where the power switch is turned on, but the refrigeration cycle is stopped and the electric dust collection air cleaner unit, the blower, and the ventilation device that are driven during the dust removal operation are stopped. It is called a stop state, and includes a state where an automatic driving condition is not satisfied and a waiting state for driving by an entry timer.

  S390 is the dust removal operation control of the lower program, and performs the dust removal operation control described below. After performing the dust removal operation control in S390, the control returns to S15 via the symbol (E) to monitor instructions from the remote controller 5 and control the operation of the air conditioner 1 to maintain a comfortable indoor environment. Keep doing.

  Next, the dust removal operation will be described with reference to FIGS. The dust removal operation is performed when the pollen watching function or the smearing function is set with the remote controller 5 and the indoor dust concentration is high, or when the pollen button 53j is pressed with the remote controller 5. When the pollen button 53j is pressed by the remote controller 5 or the pollen watch or dirt beam function is set, the air conditioner operation control turns on the pollen button flag or / and the pollen watch flag or the dirt watch flag in S30, as described above. Then, the process goes through various steps and proceeds to dust removal operation control, which is a subordinate program, in S390. As a result, the dust removal operation control, which is a lower-order program, starts in S400.

  First, when the pollen button flag is ON in S405, the process proceeds to S525, the data from the dust sensor 158 is taken, and the process proceeds to S530 via the symbol G.

  If the pollen button flag is off in S405, the process proceeds to S410 to check the state of the pollen lookout flag. If the pollen lookout flag is on, the process proceeds to S430 and the same control as described above is performed.

  If the polling watch flag is off in S410, the process proceeds to S415 to check the state of the dirt watch flag, and if the dirt watch flag is on, the process proceeds to S430 and the same control as described above is performed.

  If the dirt watch flag is off in S415, the process proceeds to S418, the blower is operated at the wind speed set in the wind speed flag, and the process proceeds to S423 to open / close the movable panel 251 according to the setting of the movable panel flag (S245, S272, S281). In S425 and S427, the up / down wind direction plate 291 and the left / right wind direction plate 295 are swung or stopped according to the up / down wind direction instruction flag and the left / right wind direction instruction flag specified by the remote controller 5, and the program returns to the upper program in S990.

  If the setting of the cycle emptying operation flag (S275, S285) is set to ON in S530, the process proceeds to S540, the calculated wind speed flag FS0 is set to the same as the current wind speed flag, and the vertical wind direction plate 291 is set in S550, S560. The left and right wind direction plates 295 are driven in accordance with instructions from the remote controller 5, and in S640, the movable panel 251 is opened or closed according to the setting of the movable panel flag (S245, S272, S281), and the process proceeds to S800 via the symbol (K). move on.

  This is because in the dust removal operation, the wind speed of the blower 31 is used with priority given to the wind speed set in the cycle operation and the air cleaning operation, so that the indoor temperature and humidity are stabilized and the comfort is not impaired.

  If the setting of the cycle emptying operation flag (S275, S285) is not on in S530, the process proceeds to S570, the calculation wind speed flag is set according to the dust concentration based on the data taken from the dust sensor 158, and the process proceeds to S580.

  When the human sensor invalid instruction flag is set to OFF in S30 and the human detection sensor 159 is enabled, if the human detection sensor 159 detects an occupant, this is determined in S580, and the process proceeds to S590. The vertical wind direction plate 291 is moved to a horizontal position and stopped at that position. The process proceeds to S560, and the left and right wind direction plates 295 and the movable panel 251 are controlled in the same manner as described above, and the process proceeds to S800 via the symbol (K).

  As a result, as shown in FIG. 13, the air flow from the air conditioner 1 is blown out in a substantially horizontal direction, so it circulates over the occupant's head to the air conditioner 1 and does not directly hit the occupant. Residents do not feel discomfort due to the airflow.

  If the human sensor invalidation instruction flag is set to ON in S30 and the human detection sensor 159 is invalid, or if the human detection sensor 159 is valid but no occupant is detected, S600 Then, the vertical wind direction plate 291 is moved to a downward position, stopped at that position, and the left and right wind direction plates 295 are swung in S610, and the process proceeds to S620.

  If the calculation wind speed flag is in the stop mode in S620, the dust concentration has not reached the dust removal operation concentration in S570, so the calculation wind speed flag remains in the stop mode and the process proceeds to S630, and the movable panel 251 as described above. And the process proceeds to S800 via the symbol K.

  If the calculated wind speed flag is other than the stop mode in S620, the process proceeds to S640. In this case, since the dust density is equal to or higher than the dust removal operation start density in S570, the calculated wind speed flag is changed to the strong mode, and the process proceeds to S630. Control proceeds to S800 via symbol K.

  As shown in FIG. 14, when there is no occupant in the room, the up-and-down wind direction plate 291 is turned downward and the wind speed is operated in the strong mode. It is wound up and circulated through the air conditioner 1 to collect dust and clean the room to a state with less dust.

  Further, as shown in FIG. 15, the dust near the floor in a wide range can be rolled up and collected by swinging the left and right wind direction plates 295. At this time, the up-and-down wind direction plate 291 may also be swung. By doing so, a wider range of dust in the room is wound up and circulated and collected in the air conditioner 1 to promote indoor cleaning. Is done.

  The movable panel flag is set in S245, S272, and S281, but the movable panel flag is set to open during the operation of the refrigeration cycle, and is set to closed otherwise. For this reason, since the movable panel flag is closed in the air cleaning operation, the ventilation operation, the pollen button, the pollen watching, the dirt watching operation, etc., the movable panel 251 is closed in these operations as shown in FIG.

  As a result, the front air suction portion 230b is closed, so that the amount of room air passing through the upper air suction portion 230a is increased, and the room air passing through the electrostatic dust collection and cleaning unit 40 provided facing the upper air suction portion 230a is also increased. To increase. For this reason, the amount of dust collected by the electric dust collection and cleaning unit 40 is also increased, and the indoor dust is more strongly removed. The above operation is summarized as shown in the table of FIG. 16, which efficiently collects dust in the room, reduces the dust concentration in a short time, and keeps the room in a dust-free state promptly. Can be controlled so that it does not directly hit the occupants, and comfortable air conditioning can be realized.

  Next, the operation control of the ventilation device 32 and the electrostatic dust collection / quiet unit 40 during the dust removal operation will be described with reference to FIG.

  When the calculation wind speed flag FS0 is in the stop mode in S800, the process proceeds to S807 and the states of the air supply operation instruction flag and the exhaust operation instruction flag are confirmed. If the air supply operation instruction flag or the exhaust operation instruction flag is turned on in S807, the operation proceeds to S812 to stop the operation of the electrostatic dust collection and quiet unit 40, proceeds to S815, stops the blower 31, and proceeds to S820 to move up and down the wind direction. The board 291 and the left / right wind direction board 295 are stopped, and the process proceeds to S990 to return to the upper program.

  If the air supply operation instruction flag and the exhaust operation instruction flag are off in S807, the process proceeds to S810 to stop the ventilator 32, further proceeds to S812, performs the same control as described above, proceeds to S990, and sets the upper program. Return.

  If the calculated wind speed flag FS0 is other than the stop mode in S800, the process proceeds to S900, the blower 31 is operated at the wind speed set in the calculated wind speed flag, and the process proceeds to S910. If the air supply operation instruction flag or the exhaust operation instruction flag is turned on in S910, the process proceeds to S980, the electrostatic dust collection / quiet unit 40 is operated, the indoor dust is also removed, and the room is quickly restored to a clean state. The process proceeds to S990 and returns to the upper program.

  If the air supply operation instruction flag and the exhaust operation instruction flag are off in S910, the process proceeds to S920 and the state of the pollen button flag is confirmed. If the pollen button flag is turned on in S920, the flow proceeds to S955, air supply operation is performed, fresh fresh air is sucked, and dust such as pollen is removed with a high-performance air supply air purification filter provided in the air supply passage. And supply it indoors. Furthermore, it progresses to S980, the electrostatic dust collection static unit 40 is drive | operated, and it progresses to S990 and returns to a high-order program.

  If the pollen button flag is off in S920, the process proceeds to S950 to check the state of the pollen lookout flag. If the polling watch flag is on in S950, the process proceeds to S955, and the control is performed as described above, and the process proceeds to S990 to return to the upper program.

  If the pollen watch flag is off in S950, the process proceeds to S970 and the state of the stain watch flag is confirmed. If the dirt watch flag is on in S970, the process proceeds to S975, exhaust operation is performed and the dirty indoor air is discharged to the outside, the process proceeds to S980, the control is performed as described above, and the process proceeds to S990 to return to the upper program.

  If the dirt watch flag is off in S970, the process proceeds to S810, the control is performed as described above, and the process proceeds to S990 to return to the upper program.
