The indoor air is passed through the indoor air heat exchanger 33 by passing through the upper air suction part 230a and the front air suction part 230b of the makeup frame 23 inside the open movable panel 251.

The indoor unit 2 is provided with a control board in the electrical equipment box which is not shown in figure, and a microcomputer is provided in the said 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 control 5 at the light receiving unit 396, and drives the indoor blower 31 and the movable panel. The indoor unit 2 is collectively controlled by controlling a motor, an up-down wind direction plate driving motor, a left-right wind direction plate driving motor, and the like, and also in charge of communication with an outdoor unit.

In the indoor unit 2, the movable panel 251 and the up-and-down wind direction plate 291 are closed, as shown in FIG. In this state, when a signal of driving operation is made from the remote control 5, a microcomputer (not shown) is cooled based on information from various sensors, if the operating signal from the remote control 5 or automatic driving is set. Or determine the operation mode, such as heating. The movable panel 251 and the up-and-down wind direction plate 291 are operated based on the said crystal | crystallization, and the flow path of an airflow is opened. At this time, although the air intake port 230b is opened, the gaze from the room is blocked by the movable panel 251 and does not reach the inside of the indoor unit 2, and does not destroy the atmosphere of the interior.

That is, the microcomputer operates a drive motor (not shown) to rotate the upper and lower wind direction plates 291 and the left and right wind direction plates 295 to the ejection angle corresponding to the instruction from the remote control 5. In addition, the microcomputer operates the movable panel driving motor for opening the movable panel 251 in association with the operation of the vertical wind direction plate 291.

Next, the microcomputer rotates the indoor blower 31 to suck the indoor air from the upper and front air intakes 230a and 230b. The indoor air sucked is controlled by the indoor heat exchanger 33 to be blown out of the air outlet 29 along the upper and lower wind direction plates 291 and the left and right wind direction plates 295 without hot or cold air or heat exchange. On the other hand, when the operation is stopped, the drive motor of the movable panel 251 and the drive motor of the up-and-down wind direction plate 291 are reversely rotated after the indoor blower 31 is stopped. In this way, control is made to return from the open state to the closed state.

The filter 231 is disposed to cover the suction side of the indoor heat exchanger 33 and is for removing dust contained in the sucked indoor air. The blower fan 311 is comprised with the horizontally flowing perfusion fan, and is arrange | positioned in the center in the indoor unit 2 so that indoor air may be inhaled from the air intake port 27 and blown out from the air blower outlet 29. As shown in FIG. The indoor heat exchanger 33 is disposed on the suction side of the blowing fan 311 and is formed in a substantially inverted V shape so as to surround the upper side and the front side of the blowing fan 311.

The dew receiving plate 35 is disposed below the lower ends of the front and rear sides of the indoor heat exchanger 33 and is provided to receive condensate generated in the indoor heat exchanger 33 during the cooling operation or the dehumidification operation. The condensate collected and discharged is discharged to the outside through the drain pipe 37. Thereby, the main air path which flows the air conditioner indoor air 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 disposed at one side in the indoor unit 2. 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 part 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, the front end of the ventilation air path 39 is opened 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, namely, air supply operation and exhaust operation, and a state of operation stop.

In addition, although not demonstrated in particular, 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. Moreover, it is also possible to stop operation | movement automatically after installing a timer in the ventilation apparatus 32, and driving for a predetermined time.

The ventilator 32 operates an exhaust damper (not shown) to exhaust the indoor air sucked from the ventilator suction port 325 to the ventilator supply / exhaust 327 and exhaust the outside air to the outside, and the ventilator supply / exhaust 327 The air supply operation to discharge the outdoor air sucked from the exhaust air to the ventilating device outlet 326 to be taken out and supplied to the room can be switched.

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 blocks the ventilation device suction port on the second side to open the air supply suction air passage, outdoor air is sucked through the air supply suction air passage. At this time, the blow-out switching damper opens the air supply blow-out air passage on the first side to block the exhaust air blow-out air, so that the outdoor air blown out through the ventilation fan blow-out port is blown into the air supply blow-out air path.

The blown outdoor air is blown into the indoor unit from the ventilation device outlet 326. And, in the present embodiment, the outdoor air sucked by the ventilation fan 321 is sucked from the ventilator supply and exhaust mechanism 327, and in the case of the air supply operation, the sucked outside air is the air supply pre-filter and the air supply hearing filter installed in the air supply path Is taken out through the room. First, after removing the dust contained in the air from the surface of the air supply pre-filter, dust having a particle diameter of 10 µm or more can be collected with high efficiency close to 99.9% and passed through the air supply hearing filter having deodorization function, which is contained in the air. Fine dust and odors are removed, cleaned and taken out indoors.

The electric dust collecting and hearing unit 40 has an upper air intake part even when the movable panel 1 is closed between the prefilter 231 and the indoor heat exchanger 33 in the flow of air flowing in the device of the indoor unit 2. 230a), a needle-shaped discharge electrode, a strip-shaped discharge counter electrode, a honeycomb-type dielectric filter, a mesh-type ground electrode, and a deodorizing filter are incorporated in the frame body.

By using the dielectric filter, the amount of dust that can be held in the filter increases, and when the filter is cleaned, charging is removed by washing with water, whereby dust can be easily separated and separated.

The dust sensor 158 detects dust in the room and outputs information of the concentration to the control unit of the air conditioner 1. The human body detecting sensor 159 transmits information regarding the presence or absence of the occupant to the control unit, and the control unit interprets the information in various ways to determine the presence of the occupant. In addition, since the case where the control of the air conditioner 1 by the human body detection sensor 159 becomes inadequate is also considered, the remote control 5 can instruct whether the human body detection sensor 159 is valid or invalid. do.

Next, the dust removal operation operation | movement of the air conditioner 1 using this dust sensor 158 is demonstrated using FIG. 5, FIG. 6, FIG. 7-FIG. 9, FIG. 5 and 6 are explanatory diagrams of a remote control function. 7 to 9 are flowcharts of main parts of the air conditioner operation control. 10 to 12 are flowcharts 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 need for pollen removal, direct the remote control 5 to the indoor unit 2 and press the pollen button 53j. . Alternatively, when the pollen comes to fly, the indoor control unit 2 instructs the setting of the pollen monitoring function from the remote control 5 via the monitoring selection button 55k.

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 may be automatically canceled at the beginning of June when the pollen monitoring function is set at the end of February, for example, by an automatic release method of 90 days or more.

The control device (not shown) of the indoor unit 2 monitors the presence or absence of a signal from the remote control 5 at a predetermined time in step 15 (hereinafter referred to as step S15 as S15), and when there is a signal. In step S20, the data from the remote control 5 is read, and the procedure goes to S25. If the data read out at S25 contains the stop instruction signal of the air conditioner 1, the flow advances to S50 to turn off various flags, and performs the stop processing of the air conditioner 1 at S60, from the remote control 5. Return to S15 to monitor the signal. In this case, the pollen monitoring flag, the pollution monitoring flag, and the human body sensor invalid indication flag are not turned off, and are kept at the last setting.

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

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. In addition, 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 of these instructions can be given. In addition, since the air supply operation instruction and the exhaust operation instruction are also controlled by the same ventilation device, 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 also 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, the automatic driving instruction flag is turned on in S30. Therefore, it is determined in S100 and the flow advances to S105. In S105, the operating type of the air conditioner 1 is selected according to the indoor and outdoor temperature and humidity conditions. If the selected 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 to the wind speed flag in S150, the flow advances to S245, the movable panel flag is set to open, and the upper and lower wind direction plates 291 in S250, S255, The left and right wind direction plates 295 are stopped or shaken along the up and down wind direction plate instruction flags and the left and right wind direction plate instruction flags from the remote control, 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. In step S175, the dehumidification operation control is performed, the wind speed calculated by the dehumidification operation control in S175 is set as the wind speed flag in S180, and the flow proceeds to S245. The same control as described above is performed in S250 and S255, and the flow goes 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. In S205, the cooling operation control is performed, the wind speed calculated by the cooling operation control in S205 is set as the wind speed flag in S210, and the flow proceeds to S245. The same control as described above is performed in S250 and S255, and the flow advances to S275.

If the selected type is not air conditioner in S125, the process proceeds to S260 via 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 operation control is performed in S265, the wind speed calculated by the air clean operation control in S265 is set to the wind speed flag in S270, the flow proceeds to S272, and the operation panel flag is set in the lung to perform the same control as described above in S250 and S255. Proceed to S275.

If it is determined in S260 that the air clean driving instruction flag is turned off, the flow advances to S280, the wind speed flag is set to stop, the flow advances to S281, the movable panel flag is set to closed, and the up and down wind direction plates and left and right wind direction plates are set in S282 and S283. Stop, the process proceeds to S285, the cycle hearing operation flag described later is set to off, and the process proceeds to S330 via the symbol (C).

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. When the instruction from the remote control 5 is heating operation, since the heating operation instruction flag is turned on in S30, it is determined in S140 and the process proceeds to S145, and the control proceeds to S275 as described above.

Similarly, when the instruction from the remote control 5 is a dehumidification operation, a cooling operation, and a comfortable operation, it determines in S170, S200, and S230 similarly, proceeds to S175, S205, and S235, it controls as mentioned above, and advances to S275.

Here, the 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 summer season by automatically setting the set temperature from the indoor temperature and the outdoor temperature.

Next, when the instruction from the remote control 5 instructs the air clean operation without 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. In S100, S140, S170, S200, S230, and S260, this is determined and the process proceeds to S265, and as described above, the process proceeds to S275 via S270, S272, S250, and S255.

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 being performed is set to on, and the flow advances to S300 via the symbol (B).

When the instruction from the remote control 5 instructs the air purifying operation accompanying the operation of the refrigeration cycle, the case where it reaches S275 through any one of the steps S145, S175, S205, and S235 as described above have. 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 reset it. 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 air supply operation control is performed in S340. The air supply operation flag is turned on, the exhaust operation flag is turned off in S345, and the flow advances 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 refrigeration cycle is stopped, and the air conditioner hearing unit, the blower, and the ventilator which are driven during the dust removal operation are stopped, and the air conditioner is stopped. It also includes the inoperable condition of the operation and 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. Keep going.

Next, the dust removal operation will be described with reference to Figs. Dust removal operation is performed when the pollen monitoring or pollution monitoring function is set by the remote control 5, and when the density of indoor dust is high, or when the pollen button 53j is pressed by the remote control 5. When the pollen button 53j is pressed with the remote control 5 or the pollen monitoring or pollution monitoring 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 sub-program, in S390 through various steps. As a result, dust removal operation control, which is a subordinate program, is started in S400.

First, when the pollen button flag is turned on in S405, the flow advances to S525 to read the data from the dust sensor 158, and the flow proceeds to S530 via the symbol (G).

When the pollen button plug is off in S405, the flow advances to S410 to check the state of the pollen monitoring flag. When the pollen monitoring flag is on, the flow proceeds to S430 to perform the same 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 same 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 in the wind speed flag, and the flow advances to S423 to open and close the movable panel 251 according to the setting of the movable panel flag (S245, S272, and S281). Then, in S425 and S427, the upper and lower wind direction plates 291 and the left and right wind direction plates 295 are rocked or stopped along the up and down wind direction instruction flags and the left and right wind direction instruction flags, which are instructed by the remote control 5, and are returned to the upper level program in S990. .

If the cycle hearing operation flag setting (S275, S285) is set to ON in S530, the flow advances to S540 to set the operational wind speed flag FS0 to be the same as the current wind speed flag, and the up-down wind direction plate 291 in S550 and S560. ), The left and right wind direction plates 295 are driven in accordance with the instructions from the remote control 5, and the movable panel 251 is opened or closed in accordance with the setting of the movable panel flag at S640 (S245, S272, S281). Proceed to S800 via symbol (K).

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

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

If the human body sensor invalid instruction flag is set to OFF in S30 and the human body sensor 159 detects the occupant while the human body sensor 159 is valid, the determination is made in S580 to proceed to S590. The wind direction plate 291 is moved to a horizontal position and stopped at that position, and the flow proceeds to S560 to control the left and right wind direction plates 295 and the movable panel 251 as described above, and proceeds to S800 through the symbol K. .

As a result, as shown in FIG. 13, since the blown air flow from the air conditioner 1 is taken out in the substantially horizontal direction, it is circulated to the air conditioner 1 through the head of the occupant and does not directly contact the occupant. Do not feel unpleasant due to airflow.

If the human body sensor invalid instruction flag is set to ON in S30 and the human body sensor 159 is invalid or the human body sensor 159 is valid, the patient proceeds to S600 when the occupant is not detected. The upper and lower wind direction plates 291 are moved to a downward position and stopped at the positions, and the left and right wind direction plates 295 are rocked at S610 to proceed to S620.

When the operational wind speed flag is in the stop mode in S620, when the dust concentration does not reach the concentration of the dust removal operation start in 3570, the operational wind speed flag proceeds to the S630 as it is in the stop mode, and the movable panel 251 as described above. ) And proceed to S800 via symbol (K).

If the computational wind speed flag is other than the stop mode in S620, the flow advances to S640. In this case, since the dust concentration is greater than or equal to the concentration of the dust removal operation start in S570, the computational wind speed flag is changed to the strong mode, and the flow proceeds to S630. The controller then proceeds to S800 via the symbol (K).

When there is no occupant in this way, as shown in Fig. 14, the top and bottom wind direction plates 291 are turned downward, and the wind speed is driven in the strong mode, so that the dust near the bottom surface having a large amount of dust is wound up in the blowout airflow in the strong mode. The air conditioner 1 is circulated and dust is collected to clean the room with less dust.

Further, as shown in Fig. 15, by shaking the left and right wind direction plates 295, dust near the bottom of a wide range can be wound up and collected. At this time, the upper and lower wind direction plates 291 may also be oscillated. In this way, a wider range of dust in the room is wound up, circulated and collected in the air conditioner 1, and the cleanliness of the room is promoted.

The movable panel flag is set in S245, S272, and S281, but during operation of the refrigeration cycle, the movable panel flag is set to open, and otherwise set to closed. For this reason, in the case of the air cleaning operation, the ventilation operation, the pollen button, the pollen monitoring, the pollution monitoring operation, and the like, the movable panel flag is closed, and in this case, the movable panel 251 is shown in FIG. It is closed.

As a result, since the front air intake unit 230b is closed, the amount of indoor air passing through the upper air intake unit 230a increases, and the electric dust collecting and hearing unit is largely installed in the upper air intake unit 230a. The room air passing through 40 also increases. This increases the amount of dust collected by the electrostatic precipitating hearing unit 40, thereby more effectively removing dust in the room. Summarizing the above operation, as shown in the table of Fig. 16, the dust in the room is efficiently collected, the concentration of dust is reduced in a short time, and the room is quickly kept low in dust, while the blowout airflow does not directly reach the occupants. It can be controlled so as to realize comfortable air conditioning.

Next, operation control of the ventilation device 32 and the electric dust collecting hearing unit 40 at the time of dust removal operation is demonstrated using FIG.

If the operational wind speed flag FS0 is in the stop mode in S800, the flow advances to S807 to check the states of the air supply operation instruction flag and the exhaust operation instruction flag. If the air supply driving instruction flag or the exhaust driving instruction flag is turned on in S807, the flow advances to S812 to stop the operation of the electric dust collecting hearing unit 40, the flow advances to S815 to stop the blower 31, and the flow proceeds to S820. The upper and lower wind direction plates 291 and the left and right wind direction plates 295 are stopped, and the process proceeds to S990 to return to the upper level program.

If the air supply driving instruction flag and the exhaust driving instruction flag are turned off in S807, the flow advances to S810 to stop the ventilator 32, further to S812 to perform the same control as described above, and to proceed to S990, where You are returned to the program.

If the operational wind speed flag FS0 is other than the stop mode in S800, the flow advances to S900 to drive the blower 31 at the wind speed set in the operational wind speed flag, and the flow advances to S910. When the air supply driving instruction flag or the exhaust driving instruction flag is turned on in S910, the flow proceeds to S980 to drive the electric dust collecting hearing unit 40, and also to remove the dust in the room and to quickly recover the room in a clean state, 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. If the pollen button flag is turned on in S920, the flow advances to S955 to perform a supply air operation to suck fresh outside air, and to remove the dust such as pollen and supply it to the room with a high-performance air supply hearing filter installed in the supply passage. In addition, the process proceeds to S980, the electric dust collecting hearing unit 40 is driven, and the process proceeds to S990 to return to the upper level program.

If the pollen button 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 S970 to check the state of the pollution monitoring flag. If the pollution monitoring flag is turned on in S970, the flow advances to S975 to perform an exhaust operation to discharge the polluted 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 S970, the process proceeds to S810 and control as described above, and the process proceeds to S990 to return to the upper level program.

A blower that flows to the air outlet and the blower; The blower motor includes a blower motor and closes the movable panel when the electric dust collecting and hearing unit is operated, and at the same time, the up-and-down wind direction plate is at an upward or maximum upward angle than horizontal.

As a result, in the case of performing the vibration damping operation in the room, the dust collector is driven by collecting the dust by the dielectric filter. At this time, since the movable panel is closed and operated, the amount of indoor air passing from the upper suction port through the electric dust collecting hearing unit unit increases, and the amount of dust collected per unit time of dust also increases, so that the concentration of dust in the room decreases rapidly. Moreover, since the up-and-down wind direction plate is made to be higher than horizontal, the air blown out from the blower outlet does not directly contact a guest, and the guest does not feel an uncomfortable airflow. In addition, the dust adhering to the lower space of the room is less likely to be rolled up with airflow, and the concentration of dust in the indoor air is rapidly reduced.

As a result, it is possible to efficiently collect dust in the room, reduce the concentration of dust in a short time, to make the room less dust, and to control the blown air so as not to directly reach the occupants, thereby providing an air conditioner that achieves comfortable air conditioning. .

In addition, according to the present embodiment, there is provided a ventilation device capable of inhaling outside air, a hearing filter provided in a suction path of the outside air, and a dust sensor capable of identifying dust floating in the air, wherein the dust sensor is specified.

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, the dust sensor detects it. When the dust concentration becomes more than a predetermined concentration, the electrostatic precipitating hearing unit is operated to collect the dust with a dielectric filter and to remove it. At this time, since the movable panel is closed and operated, the amount of indoor air passing from the upper suction port through the electric dust collecting hearing unit unit increases, and the amount of dust collected per unit time of dust also increases, so that the concentration of dust in the room decreases rapidly. Moreover, since the up-and-down wind direction plate is made to be higher than horizontal, the air blown out from the blower outlet does not directly contact a living room, and the indoor room does not feel uncomfortable airflow. In addition, the dust adhering to the lower space of the room is less likely to be rolled up with airflow, and the concentration of dust in the indoor air is rapidly reduced. 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.

This effectively collects dust inside the room while efficiently ventilating when the dust, such as pollen, is full, reducing the concentration of dust in a short time, making the room less dusty, and preventing blown air from directly reaching the patient. It is possible to obtain an air conditioner to realize a comfortable air conditioning.

In addition, according to the present embodiment, the front suction port and the upper suction port for suctioning the indoor air, the movable panel is installed on the front surface of the front suction port to open and close at least a portion of the front suction port, and electrically openable; An electrostatic precipitating hearing unit having a dielectric filter provided opposite the upper suction port, an indoor heat exchanger installed partially midway with the electrostatic precipitating hearing unit opposite the front suction port and the upper suction port, and an air conditioner installed from the lower surface to the lower part of the front face An air outlet, an up-down wind direction plate installed at the outlet, and electrically rotatable, a blower for flowing air from the air inlet through the prefilter, the electrostatic precipitating unit, and the indoor heat exchanger, and flowing to the air outlet; A blowing motor for driving the blowing device and a human body detection Documentation provided and, in the case of driving the electric dust-collecting unit government offices at the same time for closing the movable panel, to the human body detecting sensor when the person is not detected and the vertical wind direction plate downwardly.

Thereby, when there is no occupant, the airflow is blown out toward the floor surface, and in particular, the air near the floor surface that the amount of dust is large is wound up, the dust in the indoor lower space is blown up by the airflow, and the blown up dust is sucked from the air intake port. Therefore, the dust collector is collected by an electric dust collection unit to reduce the amount of dust in the indoor air while the occupants are absent, and the occupants can enjoy the indoor environment where the amount of dust is smaller than that of the initial entrance.

Thus, when there is no occupant, the dust near the bottom surface is blown up and collected to obtain an air conditioner in which the interior of the room is less dusty.

In addition, according to the present embodiment, when driving the electric dust collecting hearing unit by swinging the vertical wind direction plate up or down, the blower motor is driven so that the air volume of the blower device is the largest.

Thereby, when there is no occupant, the airflow is blown out at the maximum speed toward the floor surface, especially the air near the floor surface that the amount of dust is large is strongly wound up, and the dust of the indoor lower space is blown up by the airflow, and the amount is upwardly. The blown dust is sucked from the air inlet and efficiently collected by the electric dust collection hearing unit to reduce the amount of dust in the indoor air while there are no occupants. have.

As a result, a large amount of dust near the bottom surface can be blown up to be efficiently collected by the electric dust collecting and hearing unit to obtain an air conditioner in which the dust is less in the room while the occupants are absent.

In addition, according to the present embodiment, provided with the left and right wind direction plate which is electrically rotatable and installed at the outlet, and when the human body detection sensor is not detected by the human body sensor, the upper and lower wind direction plate to swing instead of driving downward Driving and / or rocking the left and right wind direction plates.
