  In this invention, when deleting the prohibition information memorize | stored in the memory | storage means, the air conditioner sends out the alerting | reporting information which alert | reports that the reception prohibition of the signal which a signal transmission part sends out was cancelled | released outside. .

  In the present invention, when prohibition information is stored in the storage means, when it is determined that the received signal is a release signal, the prohibition information stored in the storage means is deleted. Thereafter, when the prohibition information is not stored in the storage unit, the air conditioner stores the prohibition information in the storage unit when it is determined that the received signal is a release signal.

  According to the air conditioning system and the air conditioner of the present invention, when the prohibition information is not stored in the storage unit, the air conditioner operates according to the signal sent by the sending device and the release signal or the operation signal sent by the signal sending unit. . Further, when the prohibition signal is received, the air conditioner stores the prohibition information in the storage unit. On the other hand, when the prohibition information is stored in the storage means, the air conditioner operates according to the signal sent by the sending device and the release signal sent by the signal sending unit, and does not follow the operation signal sent by the signal sending unit. . Further, when the release signal is received, the air conditioner deletes the prohibition information from the storage means.

  Since the signal sending unit is operated by the user, the sending device sends a prohibition signal to the air conditioner. For example, in order to save energy by suppressing the power consumption of the entire air conditioning system, each user can use the air conditioner. As a general rule, the operation of the air conditioner can be prohibited while the sending device controls the operation of the air conditioner so that the user does not use it without permission or the setting is not changed without permission.

  Further, the signal sending unit operated by the user sends a release signal to the air conditioner, so that it depends on the environment of the room where the air conditioner is installed, in particular, in response to a sudden change in the environment, or Exceptionally, the user can operate the air conditioner using the signal transmission unit in consideration of the circumstances of the user in each room. Furthermore, when the sending device does not send a prohibition signal to the air conditioner, the user can arbitrarily operate the air conditioner using the signal sending unit.

When the measured time is equal to or longer than the predetermined time, the air conditioner stores the prohibition information in the storage unit.

  That is, when the operation of the air conditioner by the user is prohibited by the sending device, when the operation prohibition is canceled by the signal sending unit operated by the user, the air conditioner is sent out by the sending device only for a predetermined time. It operates according to both the signal and the signal sent out by the signal sending unit. In addition, after a predetermined time elapses, the air conditioner operates according to the signal sent by the sending device and the release signal sent by the signal sending unit, and does not follow the operation signal sent by the signal sending unit. That is, the operation of the air conditioner by the user can be automatically prohibited again.

  If the operation prohibition of the air conditioner is canceled by the user and the operation is not prohibited again, the user is always permitted to operate the air conditioner. On the other hand, after canceling the operation prohibition, by prohibiting the operation again, it is possible to prevent the user from operating the air conditioner without limitation. In addition, since the operation of the air conditioner is automatically prohibited again at the time limit, the user only has to cancel the prohibition of the operation of the air conditioner. There is no need to prohibit the operation again. For this reason, user convenience can be improved.

  Further, when the operation of the air conditioner by the user is prohibited again, a signal requesting the reception prohibition of the signal transmitted by the signal transmission unit, a signal prohibiting the reception of the signal, or the like between the air conditioner and the transmission device. Not sent or received. That is, the air conditioner can again inhibit the reception of the signal sent out by the signal sending unit regardless of the control of the sending device. For this reason, it can prevent that the burden concerning the air conditioner control of a sending device increases.

To do. After the prohibition information is deleted, when the current time is not within the range from the first time point to the second time point, the air conditioner stores the prohibition information in the storage unit.

  In other words, when the operation of the air conditioner by the user is prohibited by the sending device, the air conditioner sends the signal sent by the sending device and the signal sent by the signal sending unit from the first time point to the second time point. Operates according to both. The air conditioner operates in accordance with the signal sent by the sending device and the release signal sent by the signal sending unit from the second time until the first time, and the operation signal sent by the signal sending unit. Do not follow. That is, the prohibition of the user's operation of the air conditioner can be automatically canceled according to the current time, and can be automatically prohibited again.

  If the user does not prohibit the operation after the prohibition of the air conditioner operation prohibition by the user, the operation of the air conditioner is always permitted for the user. On the other hand, after canceling the operation prohibition, by prohibiting the operation again, it is possible to prevent the user from operating the air conditioner without limitation. In addition, since the prohibition on the operation of the air conditioner is automatically added and removed again at the time limit, the user needs to cancel the prohibition on the operation of the air conditioner. There is no need to use it again to prohibit the operation of the air conditioner. For this reason, user convenience can be improved.

  Further, when canceling the prohibition of operation of the air conditioner by the user, a signal requesting cancellation of the prohibition of reception of a signal transmitted by the signal transmission unit, a signal permitting the cancellation, or the like between the air conditioner and the transmission device. Not sent or received. Furthermore, when the operation of the air conditioner by the user is prohibited again, a signal requesting prohibition of reception of a signal transmitted by the signal transmission unit between the air conditioner and the transmission device, a signal prohibiting reception of the signal, etc. Is not sent or received. That is, the air conditioner can cancel the prohibition of accepting the signal sent out by the signal sending unit regardless of the control of the sending device, and can again inhibit the acceptance of the signal sent out by the signal sending unit. For this reason, it can prevent that the burden concerning the air conditioner control of a sending device increases.

  According to the air conditioner of the present invention, when prohibition information is stored in the storage unit, when the prohibition information is deleted from the storage unit, the air conditioner operates the air conditioner by the user using the signal sending unit. The state is prohibited from the state where the prohibition of the operation of the air conditioner by the user is canceled. For this reason, by sending notification information when the prohibition information is deleted from the storage means, the air conditioner can notify the transmission device that the prohibition of acceptance of the signal transmitted by the signal transmission unit has been lifted. .

  As a result, the sending device can grasp whether the air conditioner is in a state where the operation according to the operation signal is prohibited or in a prohibition release state. In this case, the sending device executes / suspends the operation control on the air conditioner according to the difference in the state of the air conditioner with respect to the operation signal, or, for example, the air conditioner operated by the user increases the power consumption. In this case, it is possible to reduce the power consumption of the air conditioner for which the operation by the user is prohibited, and to suppress the total power consumption to a predetermined value or less.

  According to the air conditioner of the present invention, whenever the release signal is received, the prohibition information is stored in the storage unit or the prohibition information is deleted from the storage unit. For this reason, the user can cancel the prohibition of the operation of the air conditioner using the signal transmission unit, and can again prohibit the operation of the air conditioner using the signal transmission unit after the cancellation of the prohibition of operation. That is, the user can switch the operation prohibition / prohibition release of the air conditioner by the signal transmission unit according to his / her convenience, and thus the convenience for the user can be improved.

  In addition, since the signal sending unit does not need to have a means for sending a prohibition signal, the configuration of the signal sending unit can be simplified. Furthermore, since the user can prohibit the operation of the air conditioner by operating the signal transmission unit in the same manner as when canceling the prohibition of the operation of the air conditioner, the operation of the air conditioner is prohibited. There is no need to learn a new operation method of the signal transmission unit. For this reason, the present invention has an excellent effect, such as being able to improve user convenience.

  FIG. 3 is a front view showing the appearance of the operation panel 3. A rectangular display unit 34 is disposed at the upper part of the operation panel 3 having a rectangular front view, and an operation key unit 36 is disposed at the lower part. The display unit 34 uses a liquid crystal display panel, and the operation key unit 36 has a plurality of hard keys. When the display unit 34 is configured using a touch panel, the operation key unit 36 may be configured with a soft key provided on the touch panel. Further, the display unit 34 may be formed of a fluorescent display tube.

  The CPU 30 displays various types of information based on the operation information stored in the RAM 32, the current time measured by the timer 33, or on the basis of the permission information, prohibition information, and notification information stored in the RAM 32. To display. The information displayed on the display unit 34 is the operating condition of the air conditioner 1, the current time, an operation instruction to the user, etc., or whether panel operation is permitted or prohibited in principle, or panel operation is prohibited. This is information that informs the user whether the release has been made.

  The display unit 34 shown in FIG. 3 displays an operating / stopped display 41 indicating whether the vehicle is operating or stopped, whether it is in automatic operation, heating operation, dehumidifying operation, or cooling operation. An operation content display 42 indicating whether the vehicle is in the middle is displayed. The display unit 34 has an air volume display 43 indicating the amount of air blown into the room, a wind direction display 44 indicating the direction of the air blown into the room, a clock display 45 indicating the current time measured by the timer 33, and a set temperature.

In addition, the structure which displays the temperature and humidity which the sensor part 14 of the air conditioner 1 detected, preset humidity, etc. may be sufficient.

  Further, the display unit 34 displays a user operation display 47 indicating whether panel operation is permitted or prohibited in principle, or whether the panel operation prohibition is released. When the permission information (or prohibition information) is stored in the RAM 32, the CPU 30 causes the display unit 34 to highlight the permission display 47a (or the prohibition display 47b) in the user operation display 47 and to display the prohibition display 47b (or The permission display 47a) and the release display 47c are normally displayed. The case where the permission information (or prohibition information) is stored in the RAM 32 is a case where the panel operation is permitted (or prohibited) by the central device 2, and therefore the operation panel 3 displays the permission display 47a (or prohibition display). 47b) is highlighted so as to be highlighted to notify the user that the panel operation is possible (or impossible).

  Further, when the notification information is stored in the RAM 32, the CPU 30 causes the display unit 34 to reversely display the release display 47c of the user operation display 47, and normally displays the permission display 47a and the prohibition display 47b. The case where the notification information is stored in the RAM 32 is a case where the prohibition of the panel operation by the central device 2 has been canceled, so the operation panel 3 highlights the display by highlighting the cancellation display 47c, and the user In response, the panel operation is notified.

  The operation key unit 36 is provided with an operation key 61 for switching operation / stop of the air conditioner 1.

The user operates the release key 60 to perform panel operation when panel operation is prohibited in principle.

  For example, a user who wants the air conditioner to start / end air conditioning operates the operation key 61. Each time the operation key 61 is operated by the user, the function signal corresponding to the operation command / stop command is sent to the CPU 30. Every time the function signal is received, the CPU 30 stores the function signal in the ROM 31 in association with the received function signal. A certain operation signal, in this case, an operation signal corresponding to an operation command / stop command is sent to the air conditioner 1.

  In addition, when the air conditioner 1 is in operation by operating the operation key 61, the in-operation display 41a is highlighted and highlighted in the in-operation / stop display 41a. The display 41b is normally displayed. Further, when the air conditioner 1 is stopped by operating the operation key 61, the reverse display / normal display of the operation display 41a and the operation stop display 41b is opposite to that during operation. Further, various displays other than the operating / stopped display 41, the clock display 45, and the user operation display 47 are not displayed. In this way, the operating / stopped display 41, the operation content display 42, the air volume display 43, and the wind direction display 44 are displayed in reverse display / normal display according to the operation status of the air conditioner 1, thereby The operating status of the air conditioner 1 is notified to the user.

  Furthermore, when the prohibition information is stored in the RAM 32, that is, when the panel operation is prohibited, the CPU 30 displays the prohibition display 47b on the display unit 34 for a predetermined time. An error display that blinks only during is displayed. Further, when the permission information or the notification information is stored in the RAM 32, that is, when the release key 60 is operated when the panel operation is not prohibited, the permission display 47a or the release display 47c is displayed on the display unit 34 for a predetermined time. An error display that blinks only for a while is displayed. The operation panel 3 notifies the user that the user has performed a meaningless operation by performing such an error display.

  In the operation panel 3 of the present embodiment, the release key 60 and other function keys 61, 62,... Are arranged side by side, but the function keys 61, 62,. The structure which provides the outer surface provided and the inner surface in which the release key 60 exposed when this door is opened may be sufficient. In this case, it is possible to prevent the release key 60 from being operated by mistake.

  Alternatively, the door may be locked or the release key 60 may be locked (for example, child lock) to notify only a specific user of the key storage location, unlocking procedure, and the like. Further, the release key 60 may not be provided, and a release signal may be sent to the air conditioner 1 when a predetermined operation is performed by combining the function keys 61, 62,. Furthermore, the operation key unit 36 may be provided with a numeric keypad, and in addition to the operation of the release key 60, it may be configured to require the input of a personal identification number using the numeric keypad. In the above case, by notifying only the specific user of the operation method, the code number, the position of the release key 60, etc., it is possible to prevent a user other than the specific user from canceling the prohibition of panel operation.

  4 and 5 are flowcharts showing the procedure of the control process executed by the CPU 20 of the central apparatus 2. The CPU 20 individually executes control processing for each of the air conditioners 1, 1,. First, the CPU 20 determines whether or not information from the air conditioner 1 has been received via the communication unit 26 (S11). If the information has been received via the communication unit 26 (YES in S11), the CPU 20 has received the information. It is determined whether the information is notification information, prohibition information or driving information (S12).

  When the received information is notification information (notification in S12), the CPU 20 deletes the prohibition information stored in the RAM 22 (prohibition information stored in the RAM 22 in S14 or S24 described later) and sends the notification information. The received notification information is stored in the RAM 22 in association with the air conditioner 1 (S13).

  When the received information is prohibition information (prohibited in S12), the CPU 20 deletes the notification information stored in the RAM 22 and associates the received prohibition information with the air conditioner 1 that has transmitted the prohibition information. The data is stored in the RAM 22 (S14). When the received information is operation information (operation in S12), the CPU 20 stores the received operation information in the RAM 22 in association with the air conditioner 1 that has transmitted the operation information (S15). After completing the process of S13, S14, or S15, the CPU 20 returns the process to S11. Although not shown, when the information received in S11 is environmental information, the CPU 20 stores the received environmental information in the RAM 22 in association with the air conditioner 1 that sent the environmental information, and returns the process to S11. .

  When the information sent from the air conditioner 1 is not received (NO in S11), the CPU 20 determines whether the prohibition information is stored in the RAM 22 in association with the air conditioner 1 to be controlled (S16). If the prohibition information is not stored (NO in S16), it is determined whether the notification information is stored (S17). If the notification information is stored (YES in S17), the process proceeds to S11. return. In other words, the air conditioner 1 stored in the RAM 12 in association with the notification information, that is, the air conditioner 1 for which the prohibition of panel operation is released is not selected as a control target.

  When the prohibition information and the notification information are not stored in the RAM 22 in association with the air conditioner 1 to be controlled (NO in S17), that is, when the air conditioner 1 is permitted to operate the panel, the CPU 20 1 is determined whether or not panel operation is prohibited (S21). Further, when the prohibition information is stored in the RAM 22 in association with the air conditioner 1 to be controlled (YES in S16), that is, when the air conditioner 1 is prohibited from panel operation, the CPU 20 is the air conditioner 1. It is determined whether or not panel operation is permitted (S22).

  In the central device 2, conditions regarding permission / prohibition of panel operation are set in advance by the administrator, and the CPU 20 determines whether to permit / prohibit panel operation based on the set condition. For example, when the condition that the panel operation is permitted on weekdays and the panel operation is prohibited on Saturdays and Sundays in principle is set, it is determined whether the date counted by the timer 25 is a weekday, Saturday or Sunday, Based on the determination result, it is determined whether or not panel operation is permitted / prohibited.

  When the panel operation is prohibited (YES in S21), the CPU 20 sends a prohibition signal to the air conditioner 1 via the communication unit 26 (S23), and stores the prohibition information in the RAM 22 (S24). When the panel operation is permitted (YES in S22), the CPU 20 sends a permission signal to the air conditioner 1 via the communication unit 26 (S25), and deletes the prohibition information stored in the RAM 22 (S26). When the panel operation is not prohibited (NO at S21), when the panel operation is not permitted (NO at S22), or when the processing of S24 or S26 is completed, the CPU 20 controls whether the operation of the air conditioner 1 is controlled. Is determined (S27). In this case, the CPU 20 determines whether or not to control the operation of the air conditioner 1 according to the operation information stored in the RAM 22, the environment information, and the settings input in advance by the administrator.

  When controlling the operation of the air conditioner 1 (YES in S27), the CPU 20 sends a control signal corresponding to the operation to be performed by the air conditioner 1 to the air conditioner 1 via the communication unit 26 (S28). . When the operation of the air conditioner is not controlled (NO in S27), or after the process of S28 is completed, the CPU 20 returns the process to S11.

  In the control processing as described above, the central device 2 functions as a sending device that sends a signal to the air conditioner 1, and by sending a signal to the air conditioner 1, the air conditioners 1, 1,. To control the operation. For example, the central device 2 sends a control signal to the air conditioner 1 in S28, and sends a permission signal to the air conditioner 1 in S25. Moreover, CPU20 in S23 functions as a means to send a prohibition signal to the air conditioner 1 via the communication part 26. FIG.

  The CPU 20 stores the prohibition information / notification information in the RAM 22 in association with the air conditioner 1 and deletes the notification information / prohibition information, so that panel operation is permitted or prohibited with respect to the air conditioner 1. Or whether the prohibition of panel operation has been lifted. Furthermore, the signal sent to the air conditioner 1 is changed depending on whether prohibition information or notification information is stored in the RAM 22 or whether prohibition information and notification information are not stored. For example, when panel operation is permitted, a prohibition signal is sent to the air conditioner 1, but no permission signal is sent. For this reason, meaningless signals are prevented from being sent to the air conditioner 1.

  Further, when the prohibition of panel operation is released, no signal is sent to the air conditioner 1. For this reason, the operation control of the air conditioner 1 by the central device 2 and the operation of the air conditioner 1 using the operation panel 3 by the user contradict each other, and indoor comfort, user convenience, and the like may decrease. It is prevented. Even when the prohibition of panel operation is released, a configuration in which a permission signal, a prohibition signal, a control signal, and the like are sent to the air conditioner 1 may be employed.

  6 and 7 are flowcharts showing the procedure of the operation process of the operation panel 3. First, CPU30 determines whether the information from the air conditioner 1 was received via the communication part 35 (S51), and when the information which the air conditioner 1 sent out is received (it is YES at S51), it receives. It is determined whether the received information is driving information (S52). When the received information is driving information (YES in S52), the CPU 30 stores the received driving information in the RAM 32 and displays various displays 41, 42,..., 46 (driving display) according to the received driving information. Is displayed on the unit 34 (S53), and the process returns to S51.

  If the received information is not driving information (NO in S52), the CPU 30 determines whether the received information is prohibited information, permitted information, or notification information (S54). If the received information is prohibited information (prohibited in S54), the RAM 32 The prohibition information is stored (S55), the prohibition display 47b is highlighted on the user operation display 47 of the display unit 34 (S56), and the permission display 47a and the release display 47c are normally displayed. If the received information is permission information (permitted in S54), the CPU 30 deletes the prohibition information stored in the RAM 32 (S57), and displays a permission display 47a on the user operation display 47 of the display unit 34. The display is reversed (S58), and the prohibition display 47b and the release display 47c are normally displayed.

  Further, when the received information is notification information (notification in S54), the CPU 30 deletes the prohibition information stored in the RAM 32 (S59) and displays the release display 47c on the user operation display 47 of the display unit 34. The display is reversed (S60), and the permission display 47a and the prohibition display 47b are normally displayed. After completing the process of S56, S58, or S60, the CPU 30 returns the process to S51.

  When the CPU 30 has not received the information sent by the air conditioner 1 (NO in S51), it is determined whether or not the function keys 61, 62,... Are operated by determining whether or not the function signal has been received (S71). If the function keys 61, 62,... Are not operated (NO in S71), it is determined whether or not the release key signal is received (S72), and whether or not the release key 60 is operated. When the release key 60 is not operated (NO in S72), the process returns to S51 to accept information from the air conditioner 1, or the function keys 61, 62,. Wait until

  When the function keys 61, 62,... Are operated (YES in S71), the CPU 30 sends operation signals corresponding to the function keys 61, 62,... To the air conditioner 1 via the communication unit 35 (S73). ). Further, the CPU 30 determines whether or not prohibition information is stored in the RAM 32 (S74). When the prohibition information is not stored (NO in S74), the CPU 30 displays various displays 41, 42,..., 46 (operation display) indicating the operation status when the air conditioner 1 is operated according to the sent operation signal. Is displayed on the display unit 34 (S75), and the process returns to S51.

  When prohibition information is stored (YES in S74), the CPU 30 causes the display 34 to display an error display by blinking the prohibition display 47b (S76), and returns the process to S51. Note that when prohibition information is stored, an operation signal may not be transmitted.

  When the release key 60 is operated (YES in S72), the CPU 30 sends a release signal to the air conditioner 1 via the communication unit 35 (S77). Further, the CPU 30 determines whether or not prohibition information is stored in the RAM 32 (S78). When the prohibition information is stored (YES in S78), the CPU 30 deletes the prohibition information stored in the RAM 32 (S79), and displays the release display 47c on the display unit 34 in the user operation display 47 of the display unit 34. The display is reversed (S81), and the permission display 47a and the prohibition display 47b are normally displayed. After completing the process of S81, the CPU 30 returns the process to S51.

  When the prohibition information is not stored (NO in S78), the CPU 30 causes the display unit 34 to display an error display by blinking the permission display 47a or the release display 47c that is highlighted at the time of S78 (S82). The process returns to S51. Note that when no prohibition information is stored, a release signal may not be transmitted.

  In the operation process as described above, the operation panel 3 functions as a signal transmission unit that transmits a signal to the air conditioner 1. Further, the CPU 30 in S77 functions as means for sending a release signal to the air conditioner 1 via the communication unit 35.

  The CPU 30 stores the prohibition information / notification information in the RAM 32 and deletes the notification information / prohibition information, so that the panel operation of the air conditioner 1 is permitted or prohibited, or the panel operation is prohibited. Know if it is unlocked. Further, the user operation display 47 is appropriately changed depending on whether prohibition information or notification information is stored in the RAM 12 or whether prohibition information and notification information are not stored. For this reason, the user can easily determine whether or not panel operation is possible.

  When the CPU 10 of the air conditioner 1 receives a control signal, the CPU 10 controls each part in accordance with the received control signal, and sends operation information to the central device 2 and the operation panel 3. Further, when receiving an operation signal, the CPU 10 controls each part in accordance with the received operation signal, and sends operation information to the central device 2 and the operation panel 3. That is, the control signal and the operation signal are signals for operating the air conditioner 1. In particular, if the received control signal or operation signal is a signal for causing the air conditioner 1 to start / end air conditioning, a signal for changing the set temperature / set humidity of the air conditioner 1, the CPU 10 receives the received control signal. Alternatively, in accordance with the operation signal, the air conditioning unit 15 is further activated based on the detection result of the sensor unit 14, the time measurement result of the timer 13, and the like.

  When the CPU 10 receives the permission signal, the CPU 10 sends permission information to the operation panel 3, deletes the prohibition information stored in the RAM 12, and stores the permission information. Further, when receiving the prohibition signal, the CPU 10 sends prohibition information to the operation panel 3, deletes the permission information stored in the RAM 12, and stores the prohibition information. Further, when receiving the release signal, the CPU 10 sends notification information to the central device 2, deletes the prohibition information stored in the RAM 12, stores the notification information, and further uses the timer 13 to release the release signal. Time elapsed since the receipt of.

  When permission information is stored in the RAM 12, the CPU 10 receives a control signal, a prohibition signal, and an operation signal, and controls each unit according to the received signal. However, the CPU 10 ignores the permission signal and the release signal because they are meaningless, and does not control each unit according to the received signal.

  When the prohibition information is stored in the RAM 12, the CPU 10 receives the control signal, the permission signal, and the release signal and controls each unit. However, the CPU 10 ignores the prohibition signal because it is meaningless. Further, since the panel operation is prohibited, the CPU 10 ignores the operation signal and does not control each unit according to the received operation signal. That is, the CPU 10 prohibits the air conditioner 1 itself from operating according to the received operation signal.

  When the notification information is stored in the RAM 12, the CPU 10 receives the operation signal and controls each unit. However, since it is meaningless, the CPU 10 ignores the release signal and prevents a contradiction with the user's operation. Ignore the enable signal and prohibit signal.

  That is, the permission signal, the prohibition signal, and the release signal are signals that cause the CPU 10 to store the permission information, the prohibition information, and the notification information in the RAM 12, and whether the CPU 10 receives various signals and controls each part or ignores them. Is a signal for setting.

  When the elapsed time counted by the timer 13 exceeds a predetermined time, the CPU 10 deletes the notification information stored in the RAM 12 to store the prohibition information, and sends the prohibition information to the central device 2 and the operation panel 3. When the prohibition information is stored in the RAM 12, the CPU 10 determines whether or not the current time measured by the timer 13 is within the range from the first time point to the second time point, and is within this range. Deletes the prohibition information stored in the RAM 12, stores the notification information, and sends the notification information to the central device 2 and the operation panel 3.

  Further, when the notification information is stored in the RAM 12 and the elapsed time is not measured using the timer 13, that is, not because the release signal is received, the current time measured by the timer 13 is the first time from the first time point. When the notification information is stored in the RAM 12 because it is within the range up to two time points, the CPU 10 determines whether or not the current time counted by the timer 13 is within the range from the first time point to the second time point. To do. When the current time is out of this range, the CPU 10 deletes the notification information stored in the RAM 12 to store the prohibition information, and sends the prohibition information to the central device 2 and the operation panel 3. That is, the CPU 10 determines whether the CPU 10 accepts various signals and controls each unit based on the elapsed time or the current time measured by the timer 13.

  As described above, even when the prohibition of the panel operation is released, the CPU 10 resumes the prohibition of the panel operation based on the elapsed time or the current time measured by the timer 13. Therefore, the panel operation prohibition cancellation is not permanent cancellation but temporary cancellation.

  For example, when the first time point is 11:00 pm and the second time point is 6:00 am the next day, when the operation by the operation panel 3 is prohibited, the current time measured by the timer 13 is 11 pm or later and 6 am If it is within the range before the hour, the prohibition of operation of the air conditioner 1 is temporarily released. Also, if the current time is in the range before 11:00 pm or after 6:00 am the next time, that is, when it is in the range from 6:00 am to 11:00 pm on the same day, panel operation is prohibited. Is done.

  FIGS. 8 and 9 are flowcharts showing the procedure of the air conditioning process executed by the CPU 10 of the air conditioner 1. CPU10 determines whether the signal was received from the central apparatus 2 by determining whether the signal was received via the 1st communication part 16 (S121), and when a signal was received (it is YES at S121) Then, it is determined whether notification information is stored in the RAM 12 (S122).

  If notification information is stored in the RAM 12 (YES in S122), or if no signal is received via the first communication unit 16 (NO in S121), whether or not a signal is received via the second communication unit 17 (S123), it is determined whether or not a signal is received from the operation panel 3. When the signal is not received (NO in S123), the CPU 10 returns the process to S121 and waits until the signal is received via the first communication unit 16 or the second communication unit 17.

  When a signal is received via the second communication unit 17 (YES in S123), it is determined whether the received signal is an operation signal or a release signal (S124). When the received signal is an operation signal (operation in S124) The CPU 10 determines whether or not prohibition information is stored in the RAM 12 (S125). If the prohibition information is stored (YES in S125), the received operation signal is ignored and the process proceeds to S121. return. When the prohibition information is not stored in the RAM 12 (NO in S125), that is, when the permission information or the notification information is stored, the CPU 10 controls each unit according to the received operation signal (S126), and the first communication unit 16 And driving | operation information is sent via the 2nd communication part 17 (S127), and a process is returned to S121.

  When the signal received via the second communication unit 17 is a release signal (released in S124), the CPU 10 determines whether the prohibition information is stored in the RAM 12 (S128), and the prohibition information is stored. If not (NO in S128), that is, if permission information or notification information is stored, the received release signal is ignored and the process returns to S121. When the prohibition information is stored in the RAM 12 (YES in S128), the CPU 10 deletes the prohibition information stored in the RAM 12 and stores the notification information instead (S129), via the first communication unit 16. The notification information is transmitted (S130), and the elapsed time is started using the timer 13 (S131), and the process returns to S121.

  When the notification information is not stored in the RAM 12 (NO in S122), it is determined whether the signal received via the first communication unit 16 is a control signal, a prohibition signal, or a permission signal (S141). If it is a control signal (controlled in S141), the CPU 10 controls each part in accordance with the received control signal (S142), and sends operation information via the first communication part 16 and the second communication part 17 (S143). The process returns to S121.

  When the signal received via the first communication unit 16 is a prohibition signal (prohibited in S141), the CPU 10 determines whether permission information is stored in the RAM 12 (S144), and the permission information is stored. (YES in S144), the CPU 10 deletes the permission information stored in the RAM 12, stores the prohibition information instead (S145), and sends the prohibition information via the second communication unit 17 ( S146), the process returns to S121.

  When the signal received via the first communication unit 16 is a permission signal (permitted in S141), the CPU 10 determines whether or not prohibition information is stored in the RAM 12 (S147), and the prohibition information is stored. (YES in S147), the CPU 10 deletes the prohibition information stored in the RAM 12, stores the permission information instead (S148), and sends the permission information via the second communication unit 17 ( In step S149, the process returns to step S121.

  When prohibition information is not stored in the RAM 12 (NO in S147), that is, permission information is stored, or when permission information is not stored in the RAM 12 (NO in S144), that is, prohibition information is stored. If yes, the CPU 10 ignores the accepted permission signal or prohibition signal and returns the process to S121.

  Although not shown, the CPU 10 sends the environmental information to the central device 2 at an appropriate timing (periodically or when receiving a control signal or an operation signal and operating according to the received signal).

  FIG. 10 is a flowchart showing a procedure of time / time processing executed by the CPU 10 of the air conditioner 1. The time / time processing is executed by repeatedly interrupting the air conditioning processing shown in FIGS. 8 and 9 periodically or at an appropriate timing.

  The CPU 10 determines whether or not notification information is stored in the RAM 12 (S100). If the notification information is stored (YES in S100), the timer 13 determines whether or not the elapsed time is being measured. If the elapsed time is being measured (YES in S101), it is determined whether or not the elapsed time is not less than a predetermined time (S102). When the elapsed time is not counted by the timer 13 (NO in S101), the CPU 10 determines whether or not the current time measured by the timer 13 is after the first time point and before the second time point (S103).

  If the elapsed time measured by the timer 13 is less than the predetermined time (NO in S102), the CPU 10 ends the time / time processing while continuing to count the elapsed time. If the current time measured by the timer 13 is from the first time point to the second time point (YES in S103), the CPU 10 ends the time / time process.

  When the elapsed time measured by the timer 13 is equal to or longer than the predetermined time (YES in S102), the CPU 10 ends the elapsed time measurement, deletes the notification information stored in the RAM 12, and displays the prohibition information instead. Store (S104), and send prohibition information via the first communication unit 16 and the second communication unit 17 (S105). If the current time measured by the timer 13 is before the first time point or after the second time point (NO in S103), the process proceeds to S104. After completing the process of S105, the CPU 10 ends the time / time process.

  When the notification information is not stored in the RAM 12 (NO in S100), the CPU 10 determines whether or not the prohibition information is stored in the RAM 12 (S106), and when it is stored (YES in S106), the timer It is determined whether the current time measured by 13 is after the first time point and before the second time point (S107). When the prohibition information is not stored in the RAM 12 (NO in S106), or when the current time measured by the timer 13 is before the first time or after the second time (NO in S107), the CPU 10 / End time processing.

  When the current time measured by the timer 13 is after the first time and before the second time (YES in S107), the CPU 10 deletes the prohibition information stored in the RAM 12 and stores the notification information instead (S108). ), Broadcast information is transmitted via the first communication unit 16 and the second communication unit 17 (S109). After completing the process of S109, the CPU 10 ends the time / time process.

  In the air conditioning process and the time / time process as described above, the air conditioner 1 receives a signal and operates according to the received signal. The RAM 12 functions as a storage unit that stores information. Further, the CPU 10 in S121 and S123 functions as a signal determination unit that determines whether or not the received signal is a signal transmitted from the operation panel 3 serving as a signal transmission unit. Furthermore, the CPU 10 in S141 functions as a prohibition determination unit that determines whether or not the received signal is a prohibition signal. The CPU 10 in S124 determines whether or not the received signal is a cancel signal. Functions as a means.

  The CPU 10 in S145 functions as a prohibition storage unit that stores prohibition information corresponding to the prohibition signal in the storage unit when the prohibition determination unit determines that the prohibition signal is a prohibition signal, and the CPU 10 in the case of YES in S125 stores When the prohibition information is stored in the means, the signal prohibition means prohibits the operation according to the signal other than the release signal, that is, the operation signal among the signals determined to be the signal sent by the signal sending unit. Functions as a means. Further, the CPU 10 in S129 functions as a prohibition deletion unit that deletes the prohibition information stored in the storage unit when the cancellation determination unit determines that it is a cancellation signal.

  Furthermore, the timer 13 in S131 functions as a clocking unit that starts timing when the cancellation determination unit determines that the cancellation signal is a cancellation signal, and the CPU 10 in S102 determines whether the time counted by the clocking unit is a predetermined time or more. It functions as a time determination means for determining whether or not. Further, the CPU 10 in S104 functions as a prohibition storage unit that stores prohibition information in the storage unit when the time determination unit determines that the time is equal to or longer than the predetermined time.

  Furthermore, when the CPU 10 in S103 and S107 determines that the prohibition determination unit is the prohibition signal, the time for determining whether or not the time counted by the clock unit is within the range from the first time point to the second time point. The CPU 10 in S108 functions as a prohibition deletion unit that deletes the prohibition information stored in the storage unit when the time determination unit determines that it is within the above range.

  Furthermore, when the prohibition deletion unit deletes the prohibition information stored in the storage unit, the CPU 10 in S130 and S109 sends the notification information to the outside (in this case, the central device 2) via the first communication unit 16. It functions as sending means for sending.

  The central device 2 in the air conditioning system 8 as described above can permit or in principle prohibit the panel operation by the user, unlike the conventional central device that allows or completely prohibits the panel operation by the user. it can. Further, the air conditioner 1 can temporarily cancel the operation prohibition when the panel operation is prohibited.

  When panel operation is permitted by the central device 2, the user can operate the air conditioner 1 with the operation panel 3. On the other hand, when the panel operation is basically prohibited by the central device 2, the user cannot operate the air conditioner 1 with the operation panel 3. However, when the user operates the release key 60 or when the current time is after the first time point and before the second time point, the user can operate the air conditioner 1 with the operation panel 3. For this reason, the user can improve the comfort of an indoor environment individually according to the change of an indoor environment, a user's circumstance, etc. using the air conditioner 1 irrespective of the central apparatus 2.

  Moreover, the panel operation prohibition can be canceled for a limited time, and the panel operation is automatically prohibited again based on the elapsed time or the current time. In other words, the operation of the air conditioner 1 by the operation panel 3 is not performed arbitrarily by the user, but is performed within the range permitted by the central device 2, and the cancellation of the panel operation prohibition by the user is exceptionally executed. Is done. In addition, you may make it the structure which a user can command the air conditioner 1 using the operation panel 3 for prohibition of panel operation again.

  When the central device 2 prohibits panel operation, the central device 2 uses the air conditioners 1, 1,... Without depending on the user, according to the environmental change in each room, the need for energy saving, etc. The comfort of the environment in all rooms can be improved comprehensively. In other words, the central device 2 prohibits the user from operating the air conditioners 1, 1,... While considering the convenience of the user and ensuring the user's comfort as much as possible. It is possible to perform an efficient centralized management of 1,.

  Further, when the panel operation prohibition is canceled by operating the release key 60, the user can operate the panel at any time when the panel operation is prohibited, and from the first time point to the second time point. When the panel operation prohibition is automatically canceled before, there is no need for the user to operate the release key 60 when canceling the panel operation prohibition.

  The air conditioning system 8 may be configured by one air conditioner 7 and the central device 2 each.

  In the case of the present embodiment, the central device 2 that has received the notification information sent from the air conditioner 1 does not send a control signal to the air conditioner 1. At this time, the configuration may be such that operation information and environmental information of the air conditioner 1 for which the prohibition of panel operation is released is sent from the air conditioner 1 to the central device 2. In this case, the central device 2 controls the operation of the other air conditioners 1, 1,... From the viewpoint of, for example, air conditioning efficiency and energy saving, and the air conditioning efficiency of all the air conditioners 1, 1,. The power consumption and the like can be adjusted.

  Further, the cancellation of the panel operation prohibition and the re-inhibition are executed by the air conditioner 1, but the present invention is not limited to this. For example, when the central device 2 prohibits the panel operation of the air conditioner 1, when the release key 60 is operated, the air conditioner 1 requests the central device 2 to cancel the prohibition of the panel operation, and the air conditioner In response to the request 1, the central device 2 may cancel / re-inhibit panel operation prohibition. In this case, it is not necessary to send notification information from the air conditioner 1 to the central device 2.

(The operation prohibition can be canceled by operating the release key 60. A configuration in which it is possible to select whether the operation is completely prohibited (the operation remains prohibited even if the release key 60 is operated).

Embodiment 2. FIG.
In the first embodiment, the user cancels the prohibition of panel operation using the operation panel 3, but the air conditioner 1 prohibits the panel operation again when a predetermined time elapses after the canceling of the panel operation prohibition. It was. When the user does not cancel the prohibition of the panel operation, the air conditioner 1 cancels the prohibition of the panel operation after the predetermined first time point and again disables the panel operation after the second time point.

  The configuration of the air conditioning system 8 in the present embodiment is substantially the same as the configuration of the air conditioning system 8 in the first embodiment, but the user cancels the prohibition of panel operation using the operation panel 3 and prohibits the panel operation. After canceling, the user again prohibits panel operation using the operation panel 3. In this case, the prohibition of the panel operation remains released until the user prohibits the panel operation again. Further, the panel operation remains prohibited until the user cancels the prohibition of the panel operation. That is, in the present embodiment, the panel operation is not prohibited / cancelled according to the elapsed time or the current time. That is, the time / time processing as shown in FIG. 10 is not executed.

  Below, the difference between the air-conditioning system 8 in this Embodiment and the air-conditioning system 8 of Embodiment 1 is mainly demonstrated, and the part which respond | corresponds to Embodiment 1 attaches | subjects the same code | symbol, and those description Is omitted.

  FIG. 11 is a block diagram showing a configuration of the air conditioner 7 included in the air conditioning system 8 according to Embodiment 2 of the present invention. The air conditioner 1 includes a CPU 10, a ROM 11, a RAM 12, a sensor unit 14, an air conditioning unit 15, a first communication unit 16, and a second communication unit 17, as with the air conditioner 1 of the first embodiment. 13 need not be provided.

  Further, the operation key unit 36 of the operation panel 3 includes a release / re-inhibition key 600 instead of the release key 60 of the first embodiment. Send a cancel / re-inhibit signal. The CPU 30 determines that the release / reinhibition key 600 has been operated when a release / reinhibition signal is received. The ROM 31 stores a release / re-inhibition signal and a release signal to be sent to the air conditioner 1 by the CPU 30 via the communication unit 35 when the release / re-inhibition signal is received. When the release / re-inhibition key 600 is operated, the CPU 30 sends a release signal to the air conditioner 1 via the communication unit 35.

  When the user wants to perform the panel operation when the panel operation is prohibited in principle, or when the user wants to prohibit the panel operation when the prohibition of the panel operation is canceled, the cancel / re-inhibition key 600 is used. To operate. When the permission information or the notification information is stored in the RAM 32, that is, when the cancel / re-inhibit key 600 is operated when the panel operation is not prohibited, the CPU 30 does not cause the display unit 34 to display an error.

  FIG. 12 is a flowchart showing a procedure of operation processing of the operation panel 3. The operation process according to the present embodiment includes the processes of S51 to S60 shown in FIG. 6 and the processes of S181 to S191 shown in FIG. Further, the processes of S181 and S183 to S186 are the same as the processes of S71 and S73 to S76 shown in FIG.

  When the CPU 30 has not received the function signal (NO in S181), that is, when the function keys 61, 62,... Are not operated, the CPU 30 determines whether the release / reinhibition signal has been received (S182). Whether or not the re-inhibition key 600 has been operated is determined. If the release / re-inhibition key 600 has not been operated (NO in S182), the process returns to S51 to accept information from the air conditioner 1 , Or until the function key 61, 62,... Or the cancel / re-inhibit key 600 is operated.

  When the release / re-inhibition key 600 is operated (YES in S182), the CPU 30 sends a release signal to the air conditioner 1 via the communication unit 35 (S187). Further, the CPU 30 determines whether or not prohibition information is stored in the RAM 32 (S188). When the prohibition information is stored (YES in S188), the CPU 30 deletes the prohibition information stored in the RAM 32 (S189) and displays the release display 47c on the display unit 34 on the user operation display 47 of the display unit 34. The display is reversed (S191), and the permission display 47a and the prohibition display 47b are normally displayed. After completion of the process of S191, or when prohibition information is not stored (NO in S188), the CPU 30 returns the process to S51.

  When the prohibition information is stored in the RAM 12, the CPU 10 of the air conditioner 1 sends the notification information to the central device 2 when receiving the release signal, deletes the prohibition information stored in the RAM 12, and the notification information. Remember. Further, when the notification information is stored in the RAM 12, the CPU 10 sends the prohibition information to the central device 2 and the operation panel 3 when receiving the release signal, and deletes the notification information stored in the RAM 12 and prohibits it. Remember information. Furthermore, when permission information is stored in the RAM 12, the CPU 10 ignores the received release signal when receiving the release signal.

  That is, the release signal in the present embodiment is a signal that causes the CPU 10 to store the notification information or the prohibition information in the RAM 12, and is a signal that sets whether the CPU 10 receives various signals and controls each part or ignores them. . In other words, the cancel signal functions as a signal for canceling the reception prohibition of the signal sent from the operation panel 3 or a signal for prohibiting the reception of the signal sent by the operation panel 3 in accordance with the information stored in the RAM 12. To do.

  FIGS. 13 and 14 are flowcharts showing the procedure of the air conditioning process executed by the CPU 10 of the air conditioner 1. The air conditioning process according to the present embodiment includes the processes of S211 to S220 shown in FIG. 13, the processes of S241 to S243 shown in FIG. 14, and the processes of S141 to S149 shown in FIG. 9, and S131 shown in FIG. The processing corresponding to this processing is not included. Further, the processing of S211 to S217 is the same as the processing of S121 to S127 shown in FIG.

  When the signal received via the second communication unit 17 is a release signal (released in S214), the CPU 10 determines whether the prohibition information is stored in the RAM 12 (S218), and the prohibition information is stored. (S218: YES), the prohibition information stored in the RAM 12 is deleted, the notification information is stored instead (S219), and the notification information is transmitted via the first communication unit 16 (S220). The process returns to S211.

  If the prohibition information is not stored in the RAM 12 (NO in S218), the CPU 10 determines whether the notification information is stored in the RAM 12 (S241). If the prohibition information is not stored (NO in S241), that is, When the permission information is stored, the accepted release signal is ignored and the process returns to S211. When the notification information is stored in the RAM 12 (YES in S241), the CPU 10 deletes the notification information stored in the RAM 12 and stores the prohibition information instead (S242). 2 Send prohibition information via the communication unit 17 (S243). After completing the process of S243, the CPU 10 returns the process to S211.

  When the cancellation determination unit determines that the cancellation determination unit is the cancellation signal, the cancellation determination unit deletes the prohibition information stored in the storage unit when the cancellation determination unit determines that the cancellation determination unit is the cancellation signal. When it is determined that it is, it functions as prohibition storage means for storing prohibition information in the storage means.

  The central device 2 in the air conditioning system 8 as described above can permit or in principle prohibit the panel operation by the user, unlike the conventional central device that permits or completely prohibits the panel operation by the user. it can.

  When panel operation is permitted by the central device 2, the user can operate the air conditioner 1 with the operation panel 3. On the other hand, when the panel operation is basically prohibited by the central device 2, the user cannot operate the air conditioner 1 with the operation panel 3. However, when the user operates the release / re-inhibition key 600, the user can operate the air conditioner 1 with the operation panel 3. For this reason, the user can improve the comfort of an indoor environment individually according to the change of an indoor environment, a user's circumstance, etc. using the air conditioner 1 irrespective of the central apparatus 2.

  After canceling the prohibition of panel operation, the user can return the air conditioner 7 to a state in which the panel operation is prohibited by operating the cancel / re-inhibit key 600. That is, the user can switch prohibition / prohibition of the panel operation according to his / her convenience, and thus the convenience for the user can be improved.

  Further, the operation panel 3 does not need to be provided with means for transmitting a signal for canceling the reception prohibition of the signal transmitted by the operation panel 3 and a signal for prohibiting the reception of the signal transmitted by the operation panel 3. For this reason, the configuration of the operation panel 3 is simple. Furthermore, the user only has to operate the cancel / re-inhibit key 600 when canceling the prohibition of the panel operation or when returning to the state where the panel operation is prohibited, and it is not necessary to learn a different operation method depending on each case. For this reason, user convenience can be improved.

  When the central device 2 prohibits panel operation, the central device 2 uses the air conditioners 1, 1,... Without depending on the user, according to the environmental change in each room, the need for energy saving, etc. The comfort of the environment in all the rooms can be improved comprehensively. In other words, the central device 2 prohibits the user from operating the air conditioners 1, 1,... While considering the convenience of the user and ensuring the user's comfort as much as possible. It is possible to perform an efficient centralized management of 1,.

  In addition, after the cancellation of the prohibition of the panel operation by the user, in order to prevent the user from leaving the panel operation without releasing the prohibition again, a predetermined time after receiving the cancel signal as in the first embodiment. The panel operation may be automatically prohibited again after the elapse of time. Similarly to the first embodiment, when the panel operation is prohibited, the prohibition of the panel operation may be canceled only for a predetermined time period.

  The operation panel 3 may be configured to alternately transmit different signals (for example, a release signal and a prohibition signal) to the air conditioner 1 every time the release / re-inhibition key 600 is operated. A configuration including a key and a key for sending a prohibition signal may be used. In this case, the air conditioner 1 cancels the panel operation prohibition when receiving a cancel signal from the operation panel 3 when the panel operation is prohibited, and operates when the panel operation prohibition is cancelled. When the prohibit signal from panel 3 is accepted, the panel operation is prohibited.
