Description

メンテナンス用の空気調和機用基板、及び、空気調和機のメンテナンスシステムMaintenance air conditioner substrate and air conditioner maintenance system
　本発明は、空気調和機を制御するために空気調和機に搭載されるメンテナンス用の空気調和機用基板と空気調和機のメンテナンスシステムとに関する。 The present invention relates to an air conditioner substrate for maintenance and an air conditioner maintenance system mounted on the air conditioner in order to control the air conditioner.
　一般に、異なる空調負荷（部屋の広さなど）に対応するために冷暖房の能力の異なる複数の空気調和機が販売される。その内、同一の機能を持ちかつ能力が異なる複数の機種はシリーズとしてラインナップされる。ラインナップされた複数の機種の各々では、冷暖房の能力の違いに対応して、熱交換器と、コンプレッサと、ファンのモータとの全部又は一部の仕様又は制御定数などが異なっている。一般に、シリーズにおける複数の機種の空気調和機の各々には、複数の種類のコンプレッサのいずれについても制御することができると共に、複数の種類のファンのモータのいずれについても制御することができる共通のハードウェアを有する制御基板が搭載される。 Generally, a plurality of air conditioners with different air conditioning capabilities are sold to cope with different air conditioning loads (room size, etc.). Among them, multiple models with the same functions and different abilities are lined up as a series. In each of a plurality of models in the lineup, the specifications or control constants or the like of all or part of the heat exchanger, the compressor, and the fan motor are different in accordance with the difference in the cooling / heating capability. In general, each of a plurality of types of air conditioners in the series can control any of a plurality of types of compressors and can control any of a plurality of types of fan motors. A control board having hardware is mounted.
　制御基板は、制御基板が搭載される空気調和機の機種に固有の冷暖房の能力を実現するための固有の制御定数を記憶するメモリを更に有する。制御定数の一例は、コンプレッサの動作を制御するためのものである。制御定数の一例は、ファンのモータの回転数を制御するためのものである。 The control board further has a memory for storing a specific control constant for realizing the air conditioning capability specific to the model of the air conditioner on which the control board is mounted. An example of the control constant is for controlling the operation of the compressor. An example of the control constant is for controlling the rotational speed of the fan motor.
　空気調和機に搭載される制御基板に不具合が生じると、制御基板を交換しなければならない。上述の通り制御基板は共通のハードウェアを有しているが、メモリが記憶する制御定数は制御基板が搭載される空気調和機の機種（能力）に応じて異なる。つまり、複数の機種の空気調和機の各々の制御基板は、他の機種の空気調和機の制御基板と異なる。そのため、空気調和機のメーカは、複数の機種の空気調和機のすべてに対して制御基板をいつでも交換することができる状態にするために、複数の機種の各々に対してメンテナンス用の制御基板を常に用意しておく必要がある。 If the control board mounted on the air conditioner malfunctions, the control board must be replaced. As described above, the control board has common hardware, but the control constant stored in the memory differs depending on the model (capability) of the air conditioner on which the control board is mounted. That is, each control board of a plurality of types of air conditioners is different from the control board of other types of air conditioners.

　図１の空気調和機１をメンテナンスするサービスマンは、空気調和機１の電源を落とし、空気調和機１が有する室内機２の室内機用の制御基板２７を室内機２から取り外すと共に、空気調和機１が有する室外機３の室外機用の制御基板３８を室外機３から取り外す。室内機２から室内機用の制御基板２７が取り外されると、室内機２は図２に示す室内機２Ａとなる。室外機３から室外機用の制御基板３８が取り外されると、室外機３は図２に示す室外機３Ａとなる。 A service person who maintains the air conditioner 1 of FIG. 1 turns off the power of the air conditioner 1 and removes the indoor unit control board 27 of the indoor unit 2 of the air conditioner 1 from the indoor unit 2. The control board 38 for the outdoor unit of the outdoor unit 3 included in the unit 1 is removed from the outdoor unit 3. When the indoor unit control board 27 is removed from the indoor unit 2, the indoor unit 2 becomes the indoor unit 2A shown in FIG. When the control board 38 for the outdoor unit is removed from the outdoor unit 3, the outdoor unit 3 becomes the outdoor unit 3A shown in FIG.
　サービスマンは、室内機２Ａにメンテナンス用の室内機用の空気調和機用基板７を取り付ける（Ｓ１）。これにより、サービスマンは、室内機用の制御基板２７をメンテナンス用の室内機用の空気調和機用基板７に交換する（Ｓ１）。つまり、サービスマンは、室内機の基板を交換する（Ｓ１）。サービスマンは、携帯電話機６のカメラを用い、携帯電話機６に、室内機２Ａに付けられている室内バーコード２１ａを読み取らせる（Ｓ２）。サービスマンは、室内機２Ａ及び室外機３Ａを有する空気調和機の電源を入れる（Ｓ３）。 The service person attaches the air conditioner substrate 7 for indoor unit for maintenance to the indoor unit 2A (S1). As a result, the serviceman replaces the indoor unit control board 27 with the maintenance indoor unit air conditioner board 7 (S1). That is, the service person replaces the substrate of the indoor unit (S1). The service person uses the camera of the mobile phone 6 to cause the mobile phone 6 to read the indoor barcode 21a attached to the indoor unit 2A (S2). The service person turns on the air conditioner having the indoor unit 2A and the outdoor unit 3A (S3).
　メンテナンス用の室内機用の空気調和機用基板７が室内機２Ａに取り付けられているが、メンテナンス用の室内機用の空気調和機用基板７における室内メモリ７３が有するデータのうちのメンテナンス後に用いられるデータはまだ特定されていない。そのため、室内機２Ａの表示装置４４は通常運転時及び機器の異常時に表示する情報と異なる情報を表示し、室内機２Ａの鳴動装置４５は通常運転時及び機器の異常時に出力する音と異なる音を出力する（Ｓ４）。つまり、表示装置４４及び鳴動装置４５が動作する（Ｓ４）。 Although the air conditioner board 7 for indoor unit for maintenance is attached to the indoor unit 2A, it is used after maintenance of the data of the indoor memory 73 in the air conditioner board 7 for indoor unit for maintenance. The data to be obtained has not yet been identified. Therefore, the display device 44 of the indoor unit 2A displays information different from the information displayed during normal operation and when the device is abnormal, and the sounding device 45 of the indoor unit 2A is different from the sound output during normal operation and when the device is abnormal. Is output (S4). That is, the display device 44 and the ringing device 45 operate (S4).
　具体的には、表示装置４４は、点灯及び消灯のパターン、複数存在する発光ダイオードの点灯の組み合わせ、又は色などの表現動作を、通常運転時及び機器の異常時の表現動作と異ならせて、通常運転時及び機器の異常時に表示する情報と異なる情報を表示する。鳴動装置４５は、鳴動の長さ、音階、又は鳴動のオンとオフのパターンなどの表現動作を、通常運転時及び機器の異常時の表現動作と異ならせて、通常運転時及び機器の異常時に出力する音と異なる音を出力する。すなわち、表示装置４４及び鳴動装置４５は、通常時及び異常時とは異なる表現動作で、データの指定をサービスマンに促す。通常運転時及び機器の異常時の表現動作と異なる表現動作は、表示装置４４と鳴動装置４５とのどちらか一方によって行われても構わない。 Specifically, the display device 44 is different from the expression operation at the time of normal operation and at the time of abnormality of the device, such as lighting and extinguishing patterns, combinations of lighting of a plurality of light emitting diodes, or colors. Information that is different from the information displayed during normal operation or when a device malfunctions is displayed. The ringing device 45 is different in the expression operation such as the length of the ringing, the scale, or the on / off pattern of the ringing from the expression operation during the normal operation and when the device is abnormal, and during normal operation and when the device is abnormal. A sound different from the output sound is output. In other words, the display device 44 and the ringing device 45 prompt the serviceman to specify data by an expression operation different from the normal time and the abnormal time. An expression operation different from the expression operation during normal operation and when the device is abnormal may be performed by either the display device 44 or the ring device 45.
　前述の通りステップＳ４における表示装置４４及び鳴動装置４５の動作は、ステップＳ２において携帯電話機６により読み取られた室内バーコード２１ａが特定する室内機２Ａを有する空気調和機の機種を示す情報を室内機２Ａに送信することをサービスマンに促す。サービスマンは、携帯電話機６を操作して、携帯電話機６に、室内バーコード２１ａが特定する室内機２Ａを有する空気調和機の機種を示す情報を含む赤外線を室内機２Ａに送信させる（Ｓ５）。 As described above, the operation of the display device 44 and the ringing device 45 in step S4 is performed by using information indicating the model of the air conditioner having the indoor unit 2A specified by the indoor barcode 21a read by the mobile phone 6 in step S2. Encourage service personnel to send to 2A. The service person operates the mobile phone 6 to cause the mobile phone 6 to transmit infrared rays including information indicating the model of the air conditioner having the indoor unit 2A specified by the indoor barcode 21a to the indoor unit 2A (S5). .
　室内機２Ａに取り付けられたメンテナンス用の室内機用の空気調和機用基板７の赤外線受光回路４１は、携帯電話機６から赤外線を受光する。室内マイコン７２の制御部７８は、取得部７７に対し、室内バーコード２１ａが特定する室内機２Ａを制御するためのデータを室内メモリ７３から取得することを指示する（Ｓ６）。 The infrared light receiving circuit 41 of the air conditioner substrate 7 for indoor units for maintenance attached to the indoor unit 2A receives infrared rays from the mobile phone 6. The control unit 78 of the indoor microcomputer 72 instructs the acquisition unit 77 to acquire data for controlling the indoor unit 2A specified by the indoor barcode 21a from the indoor memory 73 (S6).
　ステップＳ６の動作が行われた後、室内機２Ａの表示装置４４は、取得すべきデータを指示したことを終了したことを示す情報を表示し、室内機２Ａの鳴動装置４５は、取得すべきデータを指示したことを終了したことを示す情報を音により出力する（Ｓ７）。すなわち、表示装置４４及び鳴動装置４５は終了時の動作を行う（Ｓ７）。サービスマンは、表示装置４４及び鳴動装置４５の終了動作を受けて、室内機２Ａ及び室外機３Ａを有する空気調和機の電源を切る（Ｓ８）。 After the operation of step S6 is performed, the display device 44 of the indoor unit 2A displays information indicating that the instruction of the data to be acquired has been completed, and the ringing device 45 of the indoor unit 2A should be acquired. Information indicating that the data instruction has been completed is output by sound (S7). That is, the display device 44 and the ringing device 45 perform the operation at the end (S7). In response to the end operation of the display device 44 and the ringing device 45, the service person turns off the air conditioner having the indoor unit 2A and the outdoor unit 3A (S8).
　サービスマンは、室外機３Ａにメンテナンス用の室外機用の空気調和機用基板８を取り付ける（Ｓ９）。これにより、サービスマンは、室外機用の制御基板３８をメンテナンス用の室外機用の空気調和機用基板８に交換する（Ｓ９）。つまり、サービスマンは、室外機の基板を交換する（Ｓ９）。サービスマンは、携帯電話機６のカメラを用い、携帯電話機６に、室外機３Ａに付けられている室外バーコード３１ａを読み取らせる（Ｓ１０）。サービスマンは、室内機２Ａ及び室外機３Ａを有する空気調和機の電源を入れる（Ｓ１１）。 The service person attaches the air conditioner substrate 8 for the outdoor unit for maintenance to the outdoor unit 3A (S9). Thereby, the service person replaces the control board 38 for the outdoor unit with the air conditioner board 8 for the outdoor unit for maintenance (S9). That is, the service person replaces the substrate of the outdoor unit (S9). The service person uses the camera of the mobile phone 6 to cause the mobile phone 6 to read the outdoor barcode 31a attached to the outdoor unit 3A (S10). The service person turns on the air conditioner having the indoor unit 2A and the outdoor unit 3A (S11).
　メンテナンス用の室外機用の空気調和機用基板８が室外機３Ａに取り付けられているが、メンテナンス用の室外機用の空気調和機用基板８における室外メモリ８３が有するデータのうちのメンテナンス後に用いられるデータはまだ特定されていない。そのため、室内機２Ａと室外機３Ａとの通信により、室内機２Ａが、データが特定されていないことを把握すると、室内機２Ａの表示装置４４は通常運転時及び機器の異常時に表示する情報と異なる情報を表示し、室内機２Ａの鳴動装置４５は通常運転時及び機器の異常時に出力する音と異なる音を出力する（Ｓ１２）。つまり、表示装置４４及び鳴動装置４５が動作する（Ｓ１２）。なお、低待機電力のために室内機２Ａに室外給電制御用のリレーが搭載されている場合は、リレーをオンさせて室外機３Ａへの給電が行われた後にステップＳ１２の動作が行われる。 The maintenance-use outdoor unit air conditioner board 8 is attached to the outdoor unit 3A, and is used after maintenance of the data stored in the outdoor memory 83 in the maintenance-purpose outdoor unit air conditioner board 8. The data to be obtained has not yet been identified. Therefore, when the indoor unit 2A grasps that the data is not specified through communication between the indoor unit 2A and the outdoor unit 3A, the display device 44 of the indoor unit 2A displays information displayed during normal operation and when the device is abnormal. Different information is displayed, and the sounding device 45 of the indoor unit 2A outputs a sound different from the sound output during normal operation and when the device is abnormal (S12). That is, the display device 44 and the ringing device 45 operate (S12). In addition, when the outdoor unit power supply control relay is mounted on the indoor unit 2A for low standby power, the operation of step S12 is performed after the relay is turned on and power is supplied to the outdoor unit 3A.
　ステップＳ１２における表示装置４４及び鳴動装置４５の動作は、ステップＳ１０において携帯電話機６により読み取られた室外バーコード３１ａが特定する室外機３Ａを有する空気調和機の機種を示す情報を室内機２Ａに送信することをサービスマンに促す。サービスマンは、携帯電話機６を操作して、携帯電話機６に、室外バーコード３１ａが特定する室外機３Ａを有する空気調和機の機種を示す情報を含む赤外線を室内機２Ａに送信させる（Ｓ１３）。 In the operation of the display device 44 and the ringing device 45 in step S12, information indicating the model of the air conditioner having the outdoor unit 3A specified by the outdoor barcode 31a read by the mobile phone 6 in step S10 is transmitted to the indoor unit 2A. Encourage service personnel to do. The service person operates the mobile phone 6 to cause the mobile phone 6 to transmit infrared rays including information indicating the model of the air conditioner having the outdoor unit 3A specified by the outdoor bar code 31a to the indoor unit 2A (S13). .
　室内機２Ａに取り付けられたメンテナンス用の室内機用の空気調和機用基板７の赤外線受光回路４１は、携帯電話機６から赤外線を受光する。室内通信回路７９は、室外機３Ａを有する空気調和機の機種を示す情報をメンテナンス用の室外機用の空気調和機用基板８に送信する（Ｓ１４）。 The infrared light receiving circuit 41 of the air conditioner substrate 7 for indoor units for maintenance attached to the indoor unit 2A receives infrared rays from the mobile phone 6. The indoor communication circuit 79 transmits information indicating the model of the air conditioner having the outdoor unit 3A to the air conditioner substrate 8 for the outdoor unit for maintenance (S14).
　ステップＳ１４の動作が行われた後、メンテナンス用の室外機用の空気調和機用基板８では、室外マイコン８２の制御部８８は、ステップＳ１４においてメンテナンス用の室内機用の空気調和機用基板７が送信した情報をもとに、取得部８７に対し、室外バーコード３１ａが特定する室外機３Ａを制御するためのデータを室外メモリ８３から取得することを指示する（Ｓ１５）。 After the operation of step S14 is performed, in the air conditioner substrate 8 for the outdoor unit for maintenance, the control unit 88 of the outdoor microcomputer 82 in step S14, the air conditioner substrate 7 for the indoor unit for maintenance in step S14. Is acquired from the outdoor memory 83 (S15). The acquisition unit 87 is instructed to acquire data for controlling the outdoor unit 3A specified by the outdoor barcode 31a from the outdoor memory 83 (S15).
　つまり、メンテナンス用の室内機用の空気調和機用基板７の赤外線受光回路４１が、室内バーコード２１ａを読み取って室内バーコード２１ａが特定するいずれか１機種を示す情報を含む赤外線を携帯電話機６から受光する。室内機２Ａにおいて、赤外線受光回路４１によって受光された赤外線が含む情報が示す機種の空気調和機を制御するためのデータが特定された後に、携帯電話機６がカメラを用いて室外バーコード３１ａを読み取って室外バーコード３１ａが特定するいずれか１機種を示す情報を含む赤外線を赤外線受光回路４１に送信する。室内機２Ａは、室外バーコード３１ａが特定するいずれか１機種を示す情報をメンテナンス用の室外機用の空気調和機用基板８に送信する。室外通信回路８１は、室内機２Ａからいずれか１機種を示す情報を取得し、室外マイコン８２の制御部８８は、室外通信回路８１が受信した情報をもとに、取得部８７に対し、室外バーコード３１ａが特定する室外機３Ａを制御するためのデータを室外メモリ８３から取得することを指示する（Ｓ１５）。 That is, the infrared light receiving circuit 41 of the air conditioner substrate 7 for indoor units for maintenance reads the indoor barcode 21a and transmits infrared rays including information indicating any one model specified by the indoor barcode 21a. Receive light from. In the indoor unit 2A, after the data for controlling the air conditioner of the model indicated by the information included in the infrared light received by the infrared light receiving circuit 41 is specified, the mobile phone 6 reads the outdoor barcode 31a using the camera. Then, infrared light including information indicating any one model specified by the outdoor bar code 31a is transmitted to the infrared light receiving circuit 41. The indoor unit 2A transmits information indicating any one model specified by the outdoor barcode 31a to the air conditioner substrate 8 for the outdoor unit for maintenance. The outdoor communication circuit 81 acquires information indicating one of the models from the indoor unit 2A, and the control unit 88 of the outdoor microcomputer 82 transmits the information to the acquisition unit 87 based on the information received by the outdoor communication circuit 81. It is instructed to acquire data for controlling the outdoor unit 3A specified by the barcode 31a from the outdoor memory 83 (S15).
　ステップＳ１５の動作が行われた後、メンテナンス用の室外機用の空気調和機用基板８は、室外マイコン８２の制御部８８が取得部８７に対し室外バーコード３１ａが特定する室外機３Ａを制御するためのデータを室外メモリ８３から取得することを指示したこと示す情報をメンテナンス用の室内機用の空気調和機用基板７に送信する（Ｓ１６）。室内機２Ａの表示装置４４は、取得すべきデータを指示したことを終了したことを示す情報を表示し、室内機２Ａの鳴動装置４５は、取得すべきデータを指示したことを終了したことを示す情報を音により出力する（Ｓ１７）。すなわち、表示装置４４及び鳴動装置４５は終了時の動作を行う（Ｓ１７）。サービスマンは、表示装置４４及び鳴動装置４５の終了動作を受けて、室内機２Ａ及び室外機３Ａを有する空気調和機の電源を切る（Ｓ１８）。上述の方法により、空気調和機１のメンテナンスが行われる。 After the operation of step S15 is performed, the air conditioner board 8 for the outdoor unit for maintenance controls the outdoor unit 3A specified by the outdoor barcode 31a by the control unit 88 of the outdoor microcomputer 82 with respect to the acquisition unit 87. Information indicating that it has instructed to acquire the data to be acquired from the outdoor memory 83 is transmitted to the air conditioner substrate 7 for indoor units for maintenance (S16). The display device 44 of the indoor unit 2A displays information indicating that the instruction for the data to be acquired has been completed, and the ringing device 45 of the indoor unit 2A indicates that the instruction for the data to be acquired has been completed. The information shown is output by sound (S17). That is, the display device 44 and the ringing device 45 perform the operation at the end (S17). In response to the end operation of the display device 44 and the ringing device 45, the service person turns off the air conditioner having the indoor unit 2A and the outdoor unit 3A (S18). Maintenance of the air conditioner 1 is performed by the above-described method.
　なお、上述の方法では、図１に示す空気調和機１が有する室内機２の室内機用の制御基板２７をメンテナンス用の室内機用の空気調和機用基板７に交換すると共に、空気調和機１が有する室外機３の室外機用の制御基板３８をメンテナンス用の室外機用の空気調和機用基板８に交換している。しかしながら、室内機用の制御基板２７及び室外機用の制御基板３８の一方において不具合が生じていない場合は、不具合のない制御基板は交換する必要はない。 In the above-described method, the indoor unit control board 27 of the indoor unit 2 of the air conditioner 1 shown in FIG. 1 is replaced with a maintenance indoor unit air conditioner board 7 and the air conditioner The control board 38 for the outdoor unit of the outdoor unit 3 of 1 is replaced with the air conditioner board 8 for the outdoor unit for maintenance. However, if there is no problem on one of the control board 27 for the indoor unit and the control board 38 for the outdoor unit, it is not necessary to replace the control board having no fault.
　室内機用の制御基板２７が正常で室外機用の制御基板３８に不具合があった場合、室外機用の制御基板３８がメンテナンス用の室外機用の空気調和機用基板８に交換される。この場合、上述の方法において、室内機２Ａは室内機２に置き換えられる。室内機２が有する室内機用の制御基板２７の室内通信回路４６は、ステップＳ１４において、室外機３Ａを有する空気調和機の機種を示す情報をメンテナンス用の室外機用の空気調和機用基板８に送信する。 When the indoor unit control board 27 is normal and the outdoor unit control board 38 is defective, the outdoor unit control board 38 is replaced with a maintenance outdoor unit air conditioner board 8. In this case, the indoor unit 2A is replaced with the indoor unit 2 in the above-described method. In step S14, the indoor communication circuit 46 of the indoor unit control board 27 included in the indoor unit 2 provides information indicating the type of the air conditioner having the outdoor unit 3A to the air conditioner board 8 for maintenance outdoor unit. Send to.
　低待機電力のために室内機２又は室内機２Ａに室外給電制御用のリレーが搭載されている場合は、遠隔操作機器６０からの信号が室内機２又は室内機２Ａに入るまでは室外機３Ａへの給電は行われない。室外機３Ａへの給電が行われなければ、室内機２又は室内機２Ａはメンテナンス用の室外機用の空気調和機用基板８のデータが未確定であることを把握することができない。メンテナンス時においては、メンテナンス用の室内機用の空気調和機用基板７の赤外線受光回路４１が携帯電話機６からの室外バーコード３１ａの情報を受信した時にリレーはオンし、室外機３Ａへの給電が行われる。室外機３Ａへの給電が行われた後に、室内機２又は室内機２Ａは表示装置４４及び鳴動装置４５を用いてデータの指定を促す動作を行う。 When a relay for outdoor power supply control is mounted on the indoor unit 2 or the indoor unit 2A for low standby power, the outdoor unit 3A is used until the signal from the remote control device 60 enters the indoor unit 2 or the indoor unit 2A. Power is not supplied to If power is not supplied to the outdoor unit 3A, the indoor unit 2 or the indoor unit 2A cannot grasp that the data of the air conditioner substrate 8 for the outdoor unit for maintenance is indeterminate. At the time of maintenance, when the infrared light receiving circuit 41 of the air conditioner substrate 7 for indoor unit for maintenance receives the information of the outdoor bar code 31a from the mobile phone 6, the relay is turned on to supply power to the outdoor unit 3A. Is done. After power is supplied to the outdoor unit 3A, the indoor unit 2 or the indoor unit 2A uses the display device 44 and the ringing device 45 to perform an operation for prompting data designation.
　また、低待機電力のために室内機２又は室内機２Ａに室外給電制御用のリレーが搭載されている場合においてメンテナンス用の室外機用の空気調和機用基板８のデータが未確定であるにもかかわらず、室内機２又は室内機２Ａが通常の運転信号を受けた場合には、その信号を受けて通常運転時と同様に室外給電制御用のリレーはオンする。これにより室内機２又は室内機２Ａと室外機３Ａとの通信が確立し、メンテナンス用の室外機用の空気調和機用基板８のデータが未確定である旨の情報が室内機２又は室内機２Ａに伝わる。この信号を受けて室内機２又は室内機２Ａは表示装置４４及び鳴動装置４５を用いてデータの指定を促す動作を行う。 Further, when the outdoor unit power supply control relay is mounted on the indoor unit 2 or the indoor unit 2A for low standby power, the data of the air conditioner substrate 8 for the outdoor unit for maintenance is uncertain. However, when the indoor unit 2 or the indoor unit 2A receives a normal operation signal, the relay for outdoor power supply control is turned on in response to the signal in the same manner as during normal operation. As a result, communication between the indoor unit 2 or the indoor unit 2A and the outdoor unit 3A is established, and information indicating that the data of the air conditioner substrate 8 for the outdoor unit for maintenance is unconfirmed is the indoor unit 2 or the indoor unit. It is transmitted to 2A. In response to this signal, the indoor unit 2 or the indoor unit 2A uses the display device 44 and the ringing device 45 to perform an operation for prompting data specification.
　上述の通り、メンテナンス用の室内機用の空気調和機用基板７は、複数の機種の空気調和機の各々を制御するためのデータを記憶する室内メモリ７３を有する。具体的には、室内メモリ７３は、複数の機種の空気調和機の各々が有する室内機を制御するためのデータを記憶する。そのため、室内機用の制御基板２７が搭載されている室内機２を有する空気調和機１の機種があらかじめ決められた上記の複数の機種のうちのどの機種であっても、室内機用の制御基板２７に不具合が生じて室内機用の制御基板２７を交換する必要が生じた場合、室内機用の制御基板２７をメンテナンス用の室内機用の空気調和機用基板７に交換することができる。 As described above, the air conditioner substrate 7 for indoor units for maintenance has an indoor memory 73 for storing data for controlling each of a plurality of types of air conditioners. Specifically, the indoor memory 73 stores data for controlling the indoor units included in each of a plurality of types of air conditioners. Therefore, control for indoor units is possible regardless of the model of the plurality of predetermined models of the air conditioner 1 having the indoor unit 2 on which the control board 27 for indoor units is mounted. When a problem occurs in the board 27 and the control board 27 for the indoor unit needs to be replaced, the control board 27 for the indoor unit can be replaced with the air conditioner board 7 for the indoor unit for maintenance. .
　加えて、メンテナンス用の室内機用の空気調和機用基板７に室内機用の制御基板２７が有する機能を発揮させる場合、サーバを必要としない。すなわち、メンテナンス用の室内機用の空気調和機用基板７により、サーバを必要とすることなく、かつ上記の複数の機種の空気調和機の各々に対して十分な数のメンテナンス用の制御基板を必要とすることなく、あらかじめ決められた複数の機種の空気調和機のいずれの室内機に対しても制御基板を迅速に交換することができるという効果が得られる。 In addition, if the air conditioner board 7 for indoor units for maintenance is to exhibit the functions of the control board 27 for indoor units, no server is required. That is, the maintenance air conditioner board 7 for indoor units does not require a server, and a sufficient number of maintenance control boards are provided for each of the plurality of types of air conditioners. There is an effect that the control board can be quickly exchanged for any of the indoor units of a plurality of types of air conditioners determined in advance without the necessity.
　同様に、メンテナンス用の室外機用の空気調和機用基板８は、複数の機種の空気調和機の各々を制御するためのデータを記憶する室外メモリ８３を有する。具体的には、室外メモリ８３は、複数の機種の空気調和機の各々が有する室外機を制御するためのデータを記憶する。そのため、室外機用の制御基板３８が搭載されている室外機３を有する空気調和機１の機種があらかじめ決められた上記の複数の機種のうちのどの機種であっても、室外機用の制御基板３８に不具合が生じて室外機用の制御基板３８を交換する必要が生じた場合、室外機用の制御基板３８をメンテナンス用の室外機用の空気調和機用基板８に交換することができる。 Similarly, the maintenance-purpose outdoor unit air conditioner board 8 has an outdoor memory 83 for storing data for controlling each of a plurality of types of air conditioners. Specifically, the outdoor memory 83 stores data for controlling the outdoor unit included in each of a plurality of types of air conditioners. Therefore, control for the outdoor unit is possible regardless of the model of the plurality of predetermined models of the air conditioner 1 having the outdoor unit 3 on which the control board 38 for the outdoor unit is mounted. When a malfunction occurs in the board 38 and the control board 38 for the outdoor unit needs to be replaced, the control board 38 for the outdoor unit can be replaced with the air conditioner board 8 for the outdoor unit for maintenance. .
　加えて、メンテナンス用の室外機用の空気調和機用基板８に室外機用の制御基板３８が有する機能を発揮させる場合、サーバを必要としない。すなわち、メンテナンス用の室外機用の空気調和機用基板８により、サーバを必要とすることなく、かつ上記の複数の機種の空気調和機の各々に対して十分な数のメンテナンス用の制御基板を必要とすることなく、あらかじめ決められた複数の機種の空気調和機のいずれの室外機に対しても制御基板を迅速に交換することができるという効果が得られる。 In addition, when the air conditioner substrate 8 for maintenance outdoor unit has the functions of the outdoor unit control board 38, no server is required. That is, the maintenance air conditioner board 8 for the outdoor unit for maintenance does not require a server, and a sufficient number of maintenance control boards are provided for each of the plurality of types of air conditioners. There is an effect that the control board can be quickly replaced with respect to any of the outdoor units of a plurality of predetermined types of air conditioners without being required.
　なお、上述した実施の形態では、室内機２及び室内機２Ａには室内バーコード２１ａが付けられているが、室内バーコード２１ａは室内機２及び室内機２Ａに付けられていなくてもよい。室内バーコード２１ａが室内機２及び室内機２Ａに付けられていない場合、例えば、複数の機種の各々の室内バーコード２１ａが印刷されたシートが用いられる。室内機２及び室内機２Ａの筐体には室内機２及び室内機２Ａの機種を特定する情報が付けられているので、サービスマンは筐体に付けられている情報から室内機２及び室内機２Ａの機種を特定し、シートのなかの特定した機種に対応する室内バーコード２１ａを携帯電話機６に読み取らせてもよい。 In the above-described embodiment, the indoor bar code 21a is attached to the indoor unit 2 and the indoor unit 2A. However, the indoor bar code 21a may not be attached to the indoor unit 2 and the indoor unit 2A. When the indoor barcode 21a is not attached to the indoor unit 2 and the indoor unit 2A, for example, a sheet on which the indoor barcode 21a of each of a plurality of models is printed is used. Since information specifying the models of the indoor unit 2 and the indoor unit 2A is attached to the casings of the indoor unit 2 and the indoor unit 2A, the service person can check the indoor unit 2 and the indoor unit from the information attached to the casing. The mobile phone 6 may be made to read the indoor barcode 21a corresponding to the specified model in the seat by specifying the model of 2A.
　同様に、室外機３及び室外機３Ａには室外バーコード３１ａが付けられているが、室外バーコード３１ａは室外機３及び室外機３Ａに付けられていなくてもよい。室外バーコード３１ａが室外機３及び室外機３Ａに付けられていない場合、例えば、複数の機種の各々の室外バーコード３１ａが印刷されたシートが用いられる。室外機３及び室外機３Ａの筐体には室外機３及び室外機３Ａの機種を特定する情報が付けられているので、サービスマンは筐体に付けられている情報から室外機３及び室外機３Ａの機種を特定し、シートのなかの特定した機種に対応する室外バーコード３１ａを携帯電話機６に読み取らせてもよい。 Similarly, the outdoor unit 3 and the outdoor unit 3A are attached with the outdoor barcode 31a, but the outdoor barcode 31a may not be attached to the outdoor unit 3 and the outdoor unit 3A. When the outdoor bar code 31a is not attached to the outdoor unit 3 and the outdoor unit 3A, for example, a sheet on which the outdoor bar code 31a of each of a plurality of models is printed is used. Since information specifying the models of the outdoor unit 3 and the outdoor unit 3A is attached to the casings of the outdoor unit 3 and the outdoor unit 3A, the service person can check the outdoor unit 3 and the outdoor unit from the information attached to the casing. The 3A model may be specified, and the mobile phone 6 may read the outdoor barcode 31a corresponding to the specified model in the seat.
　上述した実施の形態では、空気調和機１をメンテナンスする場合、携帯電話機６が用いられる。しかしながら、携帯電話機６は、バーコードを読み取る機能を有するバーコード読取機器に置き換えられてもよい。バーコード読取機器は、カメラを有していて、サービスマンの操作によって、カメラを用いてバーコードを読み取り、読み取ったバーコードが特定する機種を示す情報を含む赤外線を送信する。 In the above-described embodiment, when the air conditioner 1 is maintained, the mobile phone 6 is used. However, the mobile phone 6 may be replaced with a barcode reading device having a function of reading a barcode. The barcode reading device has a camera, reads a barcode using the camera, and transmits infrared rays including information indicating a model specified by the read barcode.
　上述した実施の形態では、メンテナンス用の室内機用の空気調和機用基板７が赤外線受光回路４１を有するが、メンテナンス用の室内機用の空気調和機用基板７は赤外線受光回路４１を有しなくてもよい。その場合、赤外線受光回路４１は室内機２Ａに設けられる。また、表示装置４４、鳴動装置４５及び室内通信回路７９の一部又は全部は、メンテナンス用の室内機用の空気調和機用基板７とは別基板に設けられてもよい。室外通信回路８１は、メンテナンス用の室外機用の空気調和機用基板８とは別基板に設けられてもよい。 In the embodiment described above, the air conditioner substrate 7 for indoor unit for maintenance has the infrared light receiving circuit 41, but the air conditioner substrate 7 for indoor unit for maintenance has the infrared light receiving circuit 41. It does not have to be. In that case, the infrared light receiving circuit 41 is provided in the indoor unit 2A. Moreover, a part or all of the display device 44, the ringing device 45, and the indoor communication circuit 79 may be provided on a separate substrate from the air conditioner substrate 7 for indoor units for maintenance. The outdoor communication circuit 81 may be provided on a separate substrate from the air conditioner substrate 8 for the outdoor unit for maintenance.
　上述した実施の形態では、室内機用の制御基板２７がメンテナンス用の室内機用の空気調和機用基板７に交換される。しかしながら、メンテナンス用の室内機用の空気調和機用基板７が室内機２Ａに搭載されていて、当該メンテナンス用の室内機用の空気調和機用基板７に不具合が生じ、当該メンテナンス用の室内機用の空気調和機用基板７が新たなメンテナンス用の室内機用の空気調和機用基板７に交換されてもよい。同様に、メンテナンス用の室外機用の空気調和機用基板８が室外機３Ａに搭載されていて、当該メンテナンス用の室外機用の空気調和機用基板８に不具合が生じ、当該メンテナンス用の室外機用の空気調和機用基板８が新たなメンテナンス用の室外機用の空気調和機用基板８に交換されてもよい。 In the above-described embodiment, the control board 27 for indoor units is replaced with the air conditioner board 7 for indoor units for maintenance. However, since the air conditioner board 7 for maintenance indoor unit is mounted on the indoor unit 2A, a problem occurs in the air conditioner board 7 for indoor unit for maintenance, and the maintenance indoor unit The air conditioner substrate 7 may be replaced with a new maintenance indoor unit air conditioner substrate 7. Similarly, since the air conditioner substrate 8 for maintenance outdoor unit is mounted on the outdoor unit 3A, a problem occurs in the air conditioner substrate 8 for maintenance outdoor unit, and the maintenance outdoor unit The air conditioner substrate 8 for a machine may be replaced with a new air conditioner substrate 8 for an outdoor unit for maintenance.
　機能又はコストに対する市場の要望に応えるため多くの多機を有する上位機種から基本機能のみを有する下位機種がラインナップされている。上位機種の基板に対して下位機種では不要な回路は実装されずに量産される場合もある。また、中位機種においては上記機種から一部の機能を外したものがラインナップされ、上位機種の基板に対して中位機種の基板では不要な回路は実装されずに量産される場合もある。 ∙ In order to meet market demands for functions or costs, there is a lineup of high-end models with many multi-function machines and low-end models with only basic functions. In some cases, unnecessary circuits are not mounted on the lower model but are mass-produced on the upper model board. In addition, in the middle-level model, products obtained by removing a part of the functions from the above-mentioned model are lined up, and there is a case where unnecessary circuits are not mounted on the middle-level model board and are mass-produced with respect to the higher-level model board.
　図６は、量産機種における複数の種類の室内機用の制御基板を示す図である。図６に示すように、４つのシリーズに対応して、第１の室内機用の制御基板２７α、第２の室内機用の制御基板２７β、第３の室内機用の制御基板２７γ及び第４の室内機用の制御基板２７δが、量産の基板として用いられている。当該４つの基板の相違点は、以下の通りである。 FIG. 6 is a diagram showing a control board for a plurality of types of indoor units in a mass production model. As shown in FIG. 6, corresponding to the four series, the control board 27α for the first indoor unit, the control board 27β for the second indoor unit, the control board 27γ for the third indoor unit, and the fourth The control board 27δ for the indoor unit is used as a mass production board. The differences between the four substrates are as follows.
　図６に示す通り、第１の室内機用の制御基板２７αはＡ回路、Ｂ回路及びＣ回路を有しており、第２の室内機用の制御基板２７βはＡ回路、Ｂ回路、Ｃ回路及びＤ回路を有している。第３の室内機用の制御基板２７γはＡ回路、Ｂ回路、Ｃ回路及びＥ回路を有しており、第４の室内機用の制御基板２７δはＡ回路、Ｂ回路、Ｃ回路、Ｄ回路及びＥ回路を有している。 As shown in FIG. 6, the control board 27α for the first indoor unit has an A circuit, a B circuit, and a C circuit, and the control board 27β for the second indoor unit has an A circuit, a B circuit, and a C circuit. And a D circuit. The control board 27γ for the third indoor unit has an A circuit, a B circuit, a C circuit, and an E circuit, and the control board 27δ for the fourth indoor unit has an A circuit, a B circuit, a C circuit, and a D circuit. And an E circuit.
　ここで、Ａ回路、Ｂ回路及びＣ回路は基本回路であって、各シリーズが共通でもつ回路であり、Ａ回路、Ｂ回路及びＣ回路の各々は例えば通信回路、赤外線受信回路又はファンモータ駆動回路である。また、Ｄ回路及びＥ回路は中上位機種がもつメリットアップ機能用の回路であり、Ｄ回路及びＥ回路の各々は例えば人感センサ回路又はフィルタお掃除モータ駆動回路である。そのため、第１の室内機用の制御基板２７αが下位機種用であり、第２の室内機用の制御基板２７β及び第３の室内機用の制御基板２７γが中位機種用であり、第４の室内機用の制御基板２７δが上位機種用である。 Here, the A circuit, the B circuit, and the C circuit are basic circuits that are common to each series. Each of the A circuit, the B circuit, and the C circuit is, for example, a communication circuit, an infrared receiving circuit, or a fan motor drive Circuit. The D circuit and the E circuit are circuits for improving the merit of the middle-upper model, and each of the D circuit and the E circuit is, for example, a human sensor circuit or a filter cleaning motor drive circuit. Therefore, the control board 27α for the first indoor unit is for the lower model, the control board 27β for the second indoor unit and the control board 27γ for the third indoor unit are for the middle model, and the fourth The control board 27δ for the indoor unit is for the upper model.
　それぞれのシリーズにおいて能力の異なる複数の機種がラインナップされているため、それぞれのシリーズごとに量産基板と同一回路をもったメンテナンス用の室内機用の空気調和機用基板７（メンテナンス用の第１の室内機用の空気調和機用基板、メンテナンス用の第２の室内機用の空気調和機用基板、メンテナンス用の第３の室内機用の空気調和機用基板及びメンテナンス用の第４の室内機用の空気調和機用基板）をもつことでもメンテナンス用基板の集約のメリットが得られるが、次のようにすることで更に基板の集約が可能である。 Since there are multiple models with different capabilities in each series, the air conditioner board 7 for maintenance indoor units having the same circuit as the mass production board for each series (the first maintenance board) Air conditioner substrate for indoor unit, air conditioner substrate for second indoor unit for maintenance, air conditioner substrate for third indoor unit for maintenance, and fourth indoor unit for maintenance However, it is possible to further consolidate substrates by doing as follows.
　メンテナンス用の第４の室内機用の空気調和機用基板は回路としてフル実装であるためデータを適合させれば第１の室内機、第２の室内機、第３の室内機及び第４の室内機のシリーズのいずれの機種にも使用可能である。 Since the air conditioner board for the fourth indoor unit for maintenance is fully mounted as a circuit, the first indoor unit, the second indoor unit, the third indoor unit and the fourth indoor unit can be obtained by adapting the data. It can be used for any model in the indoor unit series.
　なお、量産機種では不要回路を実装することで量産コストが上昇するため基本的に下位機種に上位機種にも対応可能な基板を用いることはないが、メンテナンス用の空気調和機用基板においては仕様を分けることによる必要な基板の枚数の増加による諸費用（製造、輸送又は保管などによる費用）の増加を抑制できるため、共通化による多少の単価上昇よりもコストメリットが大きくなるため集約を優先する判断が可能である。 For mass-produced models, mounting the unnecessary circuit increases the mass production cost, so there is basically no need to use a board that can support the higher-order model for the lower-order model. Since the increase in various expenses (expenses due to manufacturing, transportation, storage, etc.) due to the increase in the number of necessary substrates due to separation can be suppressed, the cost advantage is greater than the slight increase in unit price due to the commonization, so priority is given to aggregation Judgment is possible.
　上述のように複数のシリーズを集約する場合、携帯電話機６は、室内バーコード２１ａが特定するシリーズを示す情報を含む赤外線を室内機２Ａに出力する。取得部７７は、携帯電話機６が出力した赤外線に含まれる情報が示すシリーズにもしたがってデータを取得する。 When collecting a plurality of series as described above, the cellular phone 6 outputs infrared rays including information indicating the series specified by the indoor barcode 21a to the indoor unit 2A. The acquisition unit 77 also acquires data according to the series indicated by the information included in the infrared rays output from the mobile phone 6.
　回路がフル実装されていなくともメンテナンス用の第３の室内機用の空気調和機用基板が第１の室内機及び第３の室内機のシリーズのいずれの機種にも対応可能であるように、搭載されるメモリの容量に応じて適用可能なシリーズ及び機種数を決めることもできる。また、遠隔操作機器６０からの信号のパターン数又は内外通信のパターン数によっても対応可能機種数が制約を受けるので、それに応じてコストミニマムなメンテナンス基板の仕様を決める必要がある。 Even if the circuit is not fully mounted, the air conditioner board for the third indoor unit for maintenance can be compatible with both models of the first indoor unit and the third indoor unit series. The applicable series and the number of models can be determined according to the capacity of the installed memory. In addition, since the number of compatible models is limited by the number of signal patterns from the remote operation device 60 or the number of patterns of internal / external communication, it is necessary to determine the specifications of a minimal cost maintenance board accordingly.
　メンテナンス用の室外機用の空気調和機用基板８に対してもメンテナンス用の室内機用の空気調和機用基板７と同様に、より多機能な基板にて適用可能なシリーズ又は機種を増やしても良い。 For the air conditioner board 8 for maintenance outdoor units, as with the air conditioner board 7 for maintenance indoor units, the number of series or models that can be applied with more multifunctional boards is increased. Also good.
　上述した実施の形態では、室内バーコード２１ａ及び室外バーコード３１ａが用いられて、携帯電話機６が、室内バーコード２１ａ及び室外バーコード３１ａを読み取って、室内バーコード２１ａ及び室外バーコード３１ａの各々が特定する機種を示す情報を含む赤外線を室内機２Ａに送信する。しかしながら、室内バーコード２１ａ及び室外バーコード３１ａは用いられなくてもよい。その場合、複数の機種のなかからいずれか１機種を選択させる画面を表示する機能が遠隔操作機器６０に設けられる。サービスマンは、機種を特定する情報が記載された銘板を参照して画面に表示された複数の機種のなかからいずれか１機種を選択し、遠隔操作機器６０に、選択されたいずれか１機種の情報を室内機２Ａに送信させる。 In the embodiment described above, the indoor barcode 21a and the outdoor barcode 31a are used, and the mobile phone 6 reads the indoor barcode 21a and the outdoor barcode 31a, and each of the indoor barcode 21a and the outdoor barcode 31a. An infrared ray including information indicating the model specified by is transmitted to the indoor unit 2A. However, the indoor barcode 21a and the outdoor barcode 31a need not be used. In that case, the remote operation device 60 is provided with a function of displaying a screen for selecting any one of a plurality of models. The service person refers to the nameplate on which the information for identifying the model is described, selects one of a plurality of models displayed on the screen, and selects one of the selected models for the remote operation device 60. Is transmitted to the indoor unit 2A.
　図６に示す４つのシリーズに対応して、メンテナンス用の第１の室内機用の空気調和機用基板、メンテナンス用の第２の室内機用の空気調和機用基板、メンテナンス用の第３の室内機用の空気調和機用基板及びメンテナンス用の第４の室内機用の空気調和機用基板の４個のメンテナンス用の室内機用の空気調和機用基板が用意される場合、４つのシリーズに対応して４個の遠隔操作機器６０が用意されてもよい。４個の遠隔操作機器６０の各々は、いずれか１機種の情報を室内機２Ａに送信する際、対応するシリーズの情報も室内機２Ａに送信する。これにより、４個のシリーズの各々に対応するメンテナンス用の室内機用の空気調和機用基板の機能を設定する際、シリーズの情報の送信が簡便になると共に、シリーズの情報の誤送信を防止することができる。 Corresponding to the four series shown in FIG. 6, the air conditioner substrate for the first indoor unit for maintenance, the air conditioner substrate for the second indoor unit for maintenance, the third for maintenance When four air conditioner boards for indoor units for maintenance are prepared: an air conditioner board for indoor units and an air conditioner board for fourth indoor unit for maintenance, four series Corresponding to the four remote control devices 60 may be prepared. When each of the four remote control devices 60 transmits information on one of the models to the indoor unit 2A, the corresponding remote control device 60 also transmits information on the corresponding series to the indoor unit 2A. As a result, when setting the function of the air conditioner board for indoor units for maintenance corresponding to each of the four series, the transmission of the series information is simplified and the erroneous transmission of the series information is prevented. can do.
　図２では、メンテナンス用の室内機用の空気調和機用基板７及びメンテナンス用の室外機用の空気調和機用基板８の各々は一枚の基板である。しかしながら、メンテナンス用の室内機用の空気調和機用基板及びメンテナンス用の室外機用の空気調和機用基板の各々は、複数枚の基板で構成されていてもよい。 In FIG. 2, each of the air conditioner substrate 7 for the indoor unit for maintenance and the air conditioner substrate 8 for the outdoor unit for maintenance is a single substrate.
