Description

空気調和装置Air conditioner
　　本発明は、室外機、室内機、及びワイヤードリモコンを備えた空気調和装置に関し、特に、待機電力の低減策に係るものである。 The present invention relates to an air conditioner including an outdoor unit, an indoor unit, and a wired remote controller, and particularly relates to a measure for reducing standby power.
　　従来より、室外機と室内機を備えた空気調和装置が知られている。例えば、特許文献１に開示の空気調和装置では、室外機と室内機とが、交流電源に繋がる一対の電力配線と一本の信号線によって互いに接続されている。そして、運転時に、交流電源から室外機と室内機へ電力が供給されると共に、室内機と室外機との間で信号が送受信される。 Conventionally, an air conditioner equipped with an outdoor unit and an indoor unit is known. For example, in the air conditioner disclosed in Patent Document 1, an outdoor unit and an indoor unit are connected to each other by a pair of power wires connected to an AC power source and a single signal line. During operation, power is supplied from the AC power source to the outdoor unit and the indoor unit, and signals are transmitted and received between the indoor unit and the outdoor unit.
　　また、この空気調和装置には、室外機側の制御部やインバータに繋がる室外機側の電源回路に開閉リレーが設けられている。この開閉リレーは、空気調和装置が運転状態から待機状態へ移行する際にオフされる。そのため、空気調和装置では、待機時に、室外機への電力供給が遮断されて室内機にのみ電力が供給されることとなり、待機時における消費電力（待機電力）が低減される。 Also, in this air conditioner, an open / close relay is provided in the power supply circuit on the outdoor unit side connected to the control unit on the outdoor unit side and the inverter. This open / close relay is turned off when the air conditioner shifts from the operating state to the standby state. Therefore, in the air conditioner, power supply to the outdoor unit is interrupted during standby and power is supplied only to the indoor unit, and power consumption (standby power) during standby is reduced.

　　ところで、特許文献１の空気調和装置では、操作用にワイヤレスリモコンが用いられているが、ワイヤレスリモコン以外にワイヤードリモコンが用いられることがある。ワイヤードリモコンは、通常、室内機に接続され、室内機から電力が供給される。そのため、ワイヤードリモコンでは、待機時においても運転時と同程度の電力が消費されてしまい、その結果、装置全体の待機電力を十分に低減できない事態が発生していた。 Incidentally, in the air conditioner of Patent Document 1, a wireless remote controller is used for operation, but a wired remote controller may be used in addition to the wireless remote controller. The wired remote controller is normally connected to an indoor unit and supplied with power from the indoor unit. For this reason, in the wired remote controller, the same amount of power as that during operation is consumed even during standby, and as a result, a situation in which standby power of the entire apparatus cannot be sufficiently reduced has occurred.
　　本発明は、かかる点に鑑みてなされたものであり、待機時におけるワイヤードリモコンの消費電力を低減することで、装置全体の待機電力を十分に低減することを目的としている。 The present invention has been made in view of this point, and aims to sufficiently reduce the standby power of the entire apparatus by reducing the power consumption of the wired remote controller during standby.
　　第１の発明は、室内機（20）、室外機（10）、及びワイヤードリモコン（30）を備え、交流電源（50）から上記室内機（20）及び室外機（10）へ電力が供給される運転状態と、上記交流電源（50）から上記室内機（20）へ電力が供給され、且つ上記室外機（10）への電力供給が遮断される待機状態との間で移行可能な空気調和装置を対象としている。そして、上記ワイヤードリモコン（30）は、表示部（34）と、上記室内機（20）との間で信号を送受信する通信部（33）と、運転状態中に上記交流電源（50）から上記室内機（20）を介して上記表示部（34）及び通信部（33）へ電力を供給し、待機状態中に上記表示部（34）及び通信部（33）の少なくとも一方への電力供給を遮断する遮断部（35）とを有していることを特徴とする。 The first invention includes an indoor unit (20), an outdoor unit (10), and a wired remote controller (30), and power is supplied from the AC power source (50) to the indoor unit (20) and the outdoor unit (10). Air conditioning that can be shifted between the operating state of the power supply and the standby state in which power is supplied from the AC power supply (50) to the indoor unit (20) and the power supply to the outdoor unit (10) is cut off Intended for equipment. The wired remote controller (30) includes a display unit (34), a communication unit (33) that transmits and receives signals between the indoor unit (20), and the AC power source (50) from the AC power source (50) during operation. Power is supplied to the display unit (34) and the communication unit (33) via the indoor unit (20), and power is supplied to at least one of the display unit (34) and the communication unit (33) during a standby state. And a blocking portion (35) for blocking.
　　上記第１の発明では、待機状態中、表示部（34）及び通信部（33）の少なくとも一方が、遮断部（35）によってオフされる。表示部（34）と通信部（33）は、ワイヤードリモコン（30）の中で消費電力が比較的大きい。そのため、ワイヤードリモコン（30）では、待機状態中の消費電力が大幅に低減される。 In the first invention, at least one of the display unit (34) and the communication unit (33) is turned off by the blocking unit (35) during the standby state. The display unit (34) and the communication unit (33) consume relatively large power in the wired remote controller (30). Therefore, in the wired remote controller (30), power consumption during the standby state is significantly reduced.
　　第２の発明は、上記第１の発明において、上記ワイヤードリモコン（30）は、上記室内機（20）から供給された電力を上記表示部（34）及び通信部（33）へ供給する電力供給部（32）を有し、上記遮断部（35）は、待機状態中に上記電力供給部（32）から上記表示部（34）及び通信部（33）の少なくとも一方への電力供給を遮断することを特徴とする。 In a second aspect based on the first aspect, the wired remote controller (30) supplies the power supplied from the indoor unit (20) to the display unit (34) and the communication unit (33). And the shut-off unit (35) shuts off power supply from the power supply unit (32) to at least one of the display unit (34) and the communication unit (33) during a standby state. It is characterized by that.
　　上記第２の発明では、室内機（20）から電力供給部（32）へ電力が供給され、電力供給部（32）から表示部（34）及び通信部（33）の少なくとも一方への電力供給が遮断される。そのため、待機状態中でも、室内機（20）から電力供給部（32）への電力供給は維持され、待機状態中に動作する他の部分へは、この電力供給部（32）から給電される。 In the second aspect of the invention, power is supplied from the indoor unit (20) to the power supply unit (32), and power is supplied from the power supply unit (32) to at least one of the display unit (34) and the communication unit (33). Is cut off. Therefore, the power supply from the indoor unit (20) to the power supply unit (32) is maintained even in the standby state, and power is supplied from the power supply unit (32) to the other parts that operate in the standby state.
　　第３の発明は、上記第１または第２の発明において、上記ワイヤードリモコン（30）は、操作ボタンを有し、上記表示部（34）への電力供給が上記遮断部（35）によって遮断されている場合に、上記操作ボタンを押すことで、該操作ボタンによる通常動作よりも優先して上記遮断部（35）による遮断を解除するように構成されていることを特徴とする。 According to a third invention, in the first or second invention, the wired remote controller (30) has an operation button, and the power supply to the display unit (34) is blocked by the blocking unit (35). In this case, when the operation button is pressed, the blocking by the blocking unit (35) is canceled in preference to the normal operation by the operation button.
　　上記第３の発明では、表示部（34）がオフ状態の時に、ユーザが操作ボタンを押すと、その操作ボタンによる通常動作（例えば、運転ボタンによる運転開始動作）は行われず、遮断部（35）による遮断が解除されて表示部（34）がオンされる。その後、表示部（34）がオン状態の時に、ユ－ザが操作ボタンを押すと、通常動作が行われる。そのため、ユーザは、通常動作を行う前（例えば、運転開始前）に表示部（34）を一旦オンして、表示内容を確認することができる。 In the third aspect of the invention, when the user presses the operation button when the display unit (34) is in the off state, the normal operation by the operation button (for example, the operation start operation by the operation button) is not performed, and the blocking unit (35 ) Is released and the display (34) is turned on. Thereafter, when the user presses the operation button while the display unit (34) is on, normal operation is performed. Therefore, the user can turn on the display unit (34) once before performing normal operation (for example, before the start of operation) and check the display contents.
　　第４の発明は、上記第１乃至第３の何れか１の発明において、上記ワイヤードリモコン（30）は、上記表示部（34）への電力供給が上記遮断部（35）によって遮断されている場合に、上記通信部（33）がエラー情報を受信することで、上記遮断部（35）による遮断を解除して該エラー情報を表示するように構成されていることを特徴とする。 In a fourth aspect based on any one of the first to third aspects, the wired remote controller (30) is configured such that power supply to the display unit (34) is blocked by the blocking unit (35). In this case, when the communication unit (33) receives the error information, the block by the blocking unit (35) is canceled and the error information is displayed.
　　上記第４の発明では、表示部（34）がオフ状態の時に、通信部（33）がエラー情報を受信すると、遮断部（35）による電力供給の遮断が解除されてそのエラー情報が表示部（34）に表示される。そのため、ユーザはエラー発生時にエラー情報を確認することができる。 In the fourth aspect of the invention, when the communication unit (33) receives error information when the display unit (34) is in the off state, the interruption of power supply by the blocking unit (35) is released, and the error information is displayed on the display unit. (34) is displayed. Therefore, the user can check the error information when an error occurs.
　　本発明によれば、ワイヤードリモコン（30）の中で消費電力が比較的大きい表示部（34）及び通信部（33）の内、少なくとも一方への電力供給を待機状態中に遮断するようにした。そのため、ワイヤードリモコン（30）では、待機状態中の消費電力（待機電力）を大幅に低減することができ、その結果、空気調和装置（1）全体の待機電力を十分に低減することができる。 According to the present invention, power supply to at least one of the display unit (34) and the communication unit (33), which consumes relatively large power in the wired remote controller (30), is cut off during the standby state. . Therefore, in the wired remote controller (30), the power consumption (standby power) during the standby state can be significantly reduced, and as a result, the standby power of the entire air conditioner (1) can be sufficiently reduced.
　　第２の発明によれば、待機状態中に、室内機（20）から電力供給部（32）へ電力を供給し、その電力供給部（32）から表示部（34）及び通信部（33）の少なくとも一方への電力供給を遮断するようにした。そのため、待機状態中に他の部分へ電力を供給して、必要動作を確保することができる。 According to the second invention, power is supplied from the indoor unit (20) to the power supply unit (32) during the standby state, and the display unit (34) and the communication unit (33) are supplied from the power supply unit (32). The power supply to at least one of them was cut off. Therefore, power can be supplied to other parts during the standby state to ensure necessary operation.
　　第３の発明によれば、表示部（34）がオフ状態の時に操作ボタンが押された場合は、その操作ボタンによる通常動作を行わず、表示部（34）をオンするようにした。これにより、ユーザは、通常動作前に表示部（34）を一旦オンして表示内容を確認することができ、誤操作を防止することができる。 According to the third invention, when the operation button is pressed when the display unit (34) is in the off state, the display unit (34) is turned on without performing the normal operation by the operation button. As a result, the user can turn on the display unit (34) once before normal operation to check the display contents, and prevent erroneous operations.
　　第４の発明によれば、表示部（34）がオフ状態の時にエラー情報を受信した場合は、表示部（34）をオンしてエラー情報を表示するようにした。これにより、ユーザはエラー発生時にエラー情報を即座に入手することができる。 According to the fourth invention, when error information is received when the display unit (34) is in the off state, the error information is displayed by turning on the display unit (34). As a result, the user can immediately obtain error information when an error occurs.

In addition to being used as the power of the power, the two-phase part of the three-phase alternating current is fed to the indoor unit (20). In addition, signal communication is performed between the outdoor unit (10) and the indoor unit (20) for the purpose of controlling the outdoor unit (10) from the indoor unit (20) side.

It is connected to the. That is, the indoor unit (20) is connected to the R phase and the S phase of the AC power supply (50) and supplied with single-phase AC. The signal line (S) is used for transmission of AC power, as described later, in addition to transmission / reception of the signal. Therefore, the signal line (S) employs a wiring member having a current capacity corresponding to the transmission power. In the present embodiment, the same wiring member as the power wiring (L) and the common line (N) is used for the signal line (S).

　　本実施形態のサスペンド状態は、一例として、空気調和装置（1）全体として消費電力が最小になる状態となっている。具体的に、本実施形態のサスペンド状態では、室外機（10）は電力を受電してそれを室内機（20）へ供給はするが、内部の各回路や電動圧縮機などには電力が供給されていない状態である。このように、サスペンド状態では、室外機（10）の各回路への電力供給が断たれ、待機電力の低減を図ることができる。 As an example, the suspended state of the present embodiment is a state in which the power consumption of the entire air conditioner (1) is minimized. Specifically, in the suspended state of this embodiment, the outdoor unit (10) receives power and supplies it to the indoor unit (20), but power is supplied to each internal circuit, electric compressor, and the like. It is a state that has not been done. Thus, in the suspended state, power supply to each circuit of the outdoor unit (10) is cut off, and standby power can be reduced.
　　一方、室内機（20）は、消費電力が最小となる状態であり、本実施形態では、室内側制御回路（23）においてリモコン（30）からの信号受信に関わる部分は、室内側電源回路（22）から電力を受けて動作している。 On the other hand, the indoor unit (20) is in a state where the power consumption is minimized. In this embodiment, the part related to signal reception from the remote control (30) in the indoor side control circuit (23) is the indoor side power circuit ( 22) It is receiving power from operation.
　　リモコン（30）は、消費電力が最小となる状態であり、ユーザーによる運転操作の受け付けが可能であると共に、通信部（33）及び表示部（34）への電力供給が遮断された状態である。なお、室内機（20）およびリモコン（30）の消費電力（待機電力）の程度はこれに限らない。 The remote control (30) is in a state where the power consumption is minimized, the user can accept driving operation, and the power supply to the communication unit (33) and the display unit (34) is cut off. . The degree of power consumption (standby power) of the indoor unit (20) and the remote control (30) is not limited to this.
　　（２）充電状態
　　充電状態とは、室外機（10）では、第２室外側電源回路（12）に充電が開始され、室外機伝送回路（11）と室内機伝送回路（21）の間の信号伝送が開始されるまでの期間の状態をいう。 (2) Charging state In the outdoor unit (10), charging is started in the second outdoor power supply circuit (12), and between the outdoor unit transmission circuit (11) and the indoor unit transmission circuit (21). This refers to the state of the period until signal transmission is started.
　　室内機（20）の電力消費は、サスペンド状態と同様である。 The power consumption of the indoor unit (20) is the same as in the suspended state.
　　リモコン（30）では、通信部（33）及び表示部（34）に電力が供給される。 In the remote control (30), power is supplied to the communication unit (33) and the display unit (34).
　　（３）ウエイト状態
　　ウエイト状態とは、運転開始時には上記充電状態を抜けた状態であり、運転停止時には運転状態（後述）から遷移する状態であり、何れも、室外機（10）が、即時、運転状態（後述）へ移行可能な状態をいう。ウエイト状態では、室外機伝送回路（11）および室外側制御回路（13）の動作も可能である。特に、運転停止時のウエイト状態（運転状態から遷移するウエイト状態）は、電動圧縮機における冷媒圧力を均圧させるためや、運転開始と運転停止を繰り返すスクジュール運転が設定されている場合などのために設けられており、その時間は例えば１０分である。 (3) Wait state The wait state is a state in which the above charging state is exited at the start of operation, and a transition from the operation state (described later) when the operation is stopped. In both cases, the outdoor unit (10) This refers to a state that can be shifted to an operating state (described later). In the weight state, the operation of the outdoor unit transmission circuit (11) and the outdoor control circuit (13) is also possible. In particular, the weight state at the time of operation stop (weight state that transitions from the operation state) is used to equalize the refrigerant pressure in the electric compressor, or when the scule operation that repeats the operation start and operation stop is set. The time is 10 minutes, for example.
　　尚、室内機（20）及びリモコン（30）の電力消費は、充電状態と同様である。 Note that the power consumption of the indoor unit (20) and the remote control (30) is the same as the charged state.
　　（４）運転状態
　　運転状態とは、第１室外側電源回路（14）からＩＰＭ及びファンモータに電力供給されて、電動圧縮機や室外ファンを運転可能、若しくは運転している状態をいう。 (4) Operational state The operational state refers to a state where electric power is supplied from the first outdoor power supply circuit (14) to the IPM and the fan motor, and the electric compressor and the outdoor fan can be operated or are operating.
　　リモコン（30）の電力消費は、充電状態と同様である。一方、室内機（20）の電力消費は、室内ファン等が運転状態となるため、前記の各状態よりも増加する。 The power consumption of the remote control (30) is the same as the charged state. On the other hand, the power consumption of the indoor unit (20) is higher than in each of the above states because the indoor fan or the like is in an operating state.
　　－運転開始動作－
　　空気調和装置（1）の運転開始動作では、サスペンド状態から、充電状態、ウェイト状態、運転状態の順に状態が移行する（図３の実線矢印）。以下、サスペンド状態から運転状態までの動作を順に説明する。 -Operation start operation-
In the operation start operation of the air conditioner (1), the state transitions from the suspended state to the charged state, the wait state, and the operating state (solid arrow in FIG. 3). Hereinafter, operations from the suspended state to the operating state will be described in order.
　　<サスペンド状態における電装系統>
　　まず、サスペンド状態における電装系統の状態を説明する。図１及び図２は、サスペンド状態におけるリレーの状態を示している。 <Electrical system in suspended state>
First, the state of the electrical system in the suspended state will be described. 1 and 2 show the state of the relay in the suspended state.
　　室外機（10）では、メインリレー（14b）がオフ状態であり、第１室外側電源回路（14）からＩＰＭ及び室外ファンモータへ電力が供給されない。また、リレー（K14R）及びリレー（K15R）はオフ状態であり、室外機伝送回路（11）は、信号線（S）との接続が断たれるとともに、電力の供給も断たれている。また、リレー（K13R）は、ノーマルクローズ接点と可動接点とが接続された状態であり、第２室外側電源回路（12）のダイオードブリッジ回路（12a）は、一方の入力が信号線（S）に接続されている。この状態では、第２室外側電源回路（12）には通電されず、室外側制御回路（13）への給電も行われない。このように、室外機（10）は、電力供給が遮断されている。 In the outdoor unit (10), the main relay (14b) is off, and power is not supplied from the first outdoor power supply circuit (14) to the IPM and the outdoor fan motor. In addition, the relay (K14R) and the relay (K15R) are in an off state, and the outdoor unit transmission circuit (11) is disconnected from the signal line (S) and also supplied with power. The relay (K13R) is a state in which the normally closed contact and the movable contact are connected. The diode bridge circuit (12a) of the second outdoor power supply circuit (12) has one input as a signal line (S). It is connected to the. In this state, the second outdoor power supply circuit (12) is not energized, and no power is supplied to the outdoor control circuit (13). Thus, the outdoor unit (10) is shut off from the power supply.
　　室内機（20）では、リレー（K2R）がオフ状態であり、信号線（S）と電力配線（L）とが電気的に非接続状態である。室内機（20）では、室内側制御回路（23）においてリモコン（30）からの信号受信にかかわる部分は、室内側電源回路（22）から電力を受けて動作している。 In the indoor unit (20), the relay (K2R) is off, and the signal line (S) and power wiring (L) are not electrically connected. In the indoor unit (20), the part related to the signal reception from the remote control (30) in the indoor side control circuit (23) operates by receiving power from the indoor side power supply circuit (22).
　　リモコン（30）では、遮断部（35）の２つのリレー（36,37）がオフ状態であり、表示部（34）及び通信部（33）は、電力供給部（32）からの電力供給が断たれている。 In the remote control (30), the two relays (36, 37) of the blocking unit (35) are in the off state, and the display unit (34) and the communication unit (33) are supplied with power from the power supply unit (32). It has been refused.
　　〈サスペンド状態から充電状態への移行〉
　　図４は、第２室外側電源回路（12）の平滑コンデンサ（12b）に充電される回路が形成された時点の各リレーの状態を示す図である。また、図５は、充電状態への移行が完了した後の各リレーの状態を示す図である。 <Transition from suspended state to charged state>
FIG. 4 is a diagram showing the state of each relay at the time when a circuit for charging the smoothing capacitor (12b) of the second outdoor side power supply circuit (12) is formed. FIG. 5 is a diagram illustrating a state of each relay after the transition to the charging state is completed.
　　ユーザーがリモコン（30）の操作ボタン（運転ボタン（39）を含む）の何れかを押すと、制御部（40）が遮断部（35）の表示部側リレー（37）をオンし、電力供給部（32）から表示部（34）へ電力が供給される。その後、ユーザが運転ボタン（39）を押すと、制御部（40）が通信部側リレー（36）をオンして、電力供給部（32）から通信部（33）へ電力が供給され、その通信部（33）から室内機（20）へ運転開始信号が送信される。 When the user presses one of the operation buttons (including the operation button (39)) on the remote control (30), the control unit (40) turns on the display side relay (37) of the shut-off unit (35) and supplies power Power is supplied from the unit (32) to the display unit (34). Thereafter, when the user presses the operation button (39), the control unit (40) turns on the communication unit side relay (36), and power is supplied from the power supply unit (32) to the communication unit (33). An operation start signal is transmitted from the communication unit (33) to the indoor unit (20).
　　室内機（20）では、Ｉ／Ｆ回路（24）が運転開始信号を受信すると、室内側制御回路（23）がリレー（K2R）をオンにする。そうすると、前記三相交流のＲ相から、電力配線（L）、リレー（K2R）、第１ダイオード（D1）、信号線（S）、及びリレー（K13R）を介して第２室外側電源回路（12）に到る経路が形成される。これにより、第２室外側電源回路（12）の平滑コンデンサ（12b）が充電される回路が形成される（図４参照）。 In the indoor unit (20), when the I / F circuit (24) receives the operation start signal, the indoor side control circuit (23) turns on the relay (K2R). Then, from the R phase of the three-phase alternating current, the second outdoor power supply circuit (L), the relay (K2R), the first diode (D1), the signal line (S), and the relay (K13R) are connected. The route to 12) is formed. Thereby, a circuit is formed in which the smoothing capacitor (12b) of the second outdoor power supply circuit (12) is charged (see FIG. 4).
　　室外機（10）では、平滑コンデンサ（12b）が充電されてスイッチング電源（12c）への入力が安定し、スイッチング電源（12c）が規定の直流電圧（この例では５Ｖ）を出力できるようになると、室外側制御回路（13）が起動する。起動した室外側制御回路（13）は、リレー（K13R）のコイルに通電させて、ノーマルオープン接点と可動接点とを接続状態とする。これにより、ダイオードブリッジ回路（12a）の一方の入力は、前記三相交流のＲ相に、室外機（10）内の送電経路を介して接続される。すなわち、室外側制御回路（13）は、信号線（S）を経由せずに交流電源（50）から電力供給された状態に切り換わる（図５参照）。こうして、サスペンド状態から充電状態への移行が完了する。 In the outdoor unit (10), when the smoothing capacitor (12b) is charged and the input to the switching power supply (12c) is stabilized, the switching power supply (12c) can output the specified DC voltage (5 V in this example). The outdoor control circuit (13) is activated. The activated outdoor control circuit (13) energizes the coil of the relay (K13R) to connect the normally open contact and the movable contact. Thereby, one input of the diode bridge circuit (12a) is connected to the R phase of the three-phase alternating current via the power transmission path in the outdoor unit (10). That is, the outdoor control circuit (13) switches to a state where power is supplied from the AC power supply (50) without passing through the signal line (S) (see FIG. 5). Thus, the transition from the suspended state to the charged state is completed.
　　〈充電状態からウエイト状態への移行〉
　　図６は、ウエイト状態への移行完了時における各リレーの状態を示す図である。室内機（20）では、リレー（K2R）をオンにしてから所定の時間（室外側制御回路（13）が起動するのに十分な時間）が経過した後に、リレー（K2R）をオフにする。これにより、信号線（S）を信号の送受信に使用できるようになる。 <Transition from charge state to wait state>
FIG. 6 is a diagram illustrating the state of each relay when the transition to the wait state is completed. In the indoor unit (20), the relay (K2R) is turned off after a predetermined time (a time sufficient for starting the outdoor control circuit (13)) has elapsed since the relay (K2R) was turned on. As a result, the signal line (S) can be used for signal transmission and reception.
　　室外機（10）では、リレー（K2R）がオフになったのを見計らって、室外側制御回路（13）は、リレー（K15R）をオンにし、室外機伝送回路（11）に電力が供給された状態にするとともに、リレー（K14R）をオンにする。これにより、室外機伝送回路（11）内の通信回路が、信号線（S）及び共通線（N）を介して室内機伝送回路（21）と接続され、室内機伝送回路（21）と通信可能な状態になる。これで、空気調和装置（1）は、前記充電状態を抜け、即時運転状態へ移行可能な状態（すなわちウエイト状態）となる。 In the outdoor unit (10), the outdoor control circuit (13) turns on the relay (K15R) and power is supplied to the outdoor unit transmission circuit (11) in anticipation of the relay (K2R) being turned off. And turn on the relay (K14R). As a result, the communication circuit in the outdoor unit transmission circuit (11) is connected to the indoor unit transmission circuit (21) via the signal line (S) and the common line (N), and communicates with the indoor unit transmission circuit (21). It becomes possible. As a result, the air conditioner (1) enters a state where it can exit the charging state and shift to the immediate operation state (that is, a wait state).
　　〈ウエイト状態から運転状態への移行〉
　　図７は、運転状態における各リレーの状態を示す図である。ウエイト状態から運転状態への移行する際には、室外側制御回路（13）は、２つのメインリレー（14b）をオンにする。これにより、第１室外側電源回路（14）によって、ＩＰＭや室外ファンモータに電力が供給されて、電動圧縮機などが運転状態になり、例えば冷房が行われる。 <Transition from wait state to operation state>
FIG. 7 is a diagram showing the state of each relay in the operating state. When shifting from the wait state to the operation state, the outdoor control circuit (13) turns on the two main relays (14b). As a result, electric power is supplied to the IPM and the outdoor fan motor by the first outdoor power supply circuit (14), and the electric compressor and the like are put into operation, for example, cooling is performed.
　　－運転停止動作－
　　空気調和装置（1）の運転停止動作では、運転状態から、ウェイト状態、サスペンド状態の順に状態が移行する（図３の点線矢印）。以下、運転状態からサスペンド状態までの動作を順に説明する。 -Stop operation-
In the operation stop operation of the air conditioner (1), the state shifts from the operation state to the wait state and the suspend state (dotted arrow in FIG. 3). Hereinafter, operations from the operating state to the suspended state will be described in order.
　　<運転状態からウエイト状態への移行>
　　運転状態中に、ユーザーがリモコン（30）の運転ボタン（39）を押すと、リモコン（30）は室内機（20）へ運転停止信号を送信し、その後、室内機（20）は室外機（10）へ運転停止信号を送信する。 <Transition from operating state to wait state>
When the user presses the drive button (39) on the remote control (30) during operation, the remote control (30) sends a stop signal to the indoor unit (20), and then the indoor unit (20) Send the operation stop signal to 10).
　　室外機（10）では、運転停止信号を受信すると、室外側制御回路（13）が第１室外側電源回路（14）のメインリレー（14b）をオンからオフに切り換える（図６参照）。これにより、ＩＰＭや室外ファンモータへの電力供給が遮断され、電動圧縮機等が停止する。こうして、運転状態からウエイト状態への移行が完了する。 In the outdoor unit (10), when the operation stop signal is received, the outdoor control circuit (13) switches the main relay (14b) of the first outdoor power supply circuit (14) from on to off (see FIG. 6). Thereby, the power supply to the IPM and the outdoor fan motor is cut off, and the electric compressor and the like are stopped. Thus, the transition from the operating state to the wait state is completed.
　　〈ウエイト状態からサスペンド状態への移行〉
　　ウェイト状態では、まず、リモコン（30）が、所定時間を経過したか否かで、サスペンド状態への移行の可否を判定する。所定時間が経過すると、リモコン（30）はサスペンド状態へ移行可能と判定する。その後、リモコン（30）は室内機（20）へ遮断要求信号を送信し、室内機（20）は室外機（10）へ遮断要求信号を送信する。 <Transition from wait state to suspend state>
In the wait state, first, the remote controller (30) determines whether or not it is possible to shift to the suspend state based on whether or not a predetermined time has elapsed. When the predetermined time has elapsed, the remote controller (30) determines that the transition to the suspended state is possible. Thereafter, the remote controller (30) transmits a blocking request signal to the indoor unit (20), and the indoor unit (20) transmits a blocking request signal to the outdoor unit (10).
　　室外機（10）では、室外機伝送回路（11）が遮断要求信号を受信すると、室外側制御回路（13）が、リレー（K14R）とリレー（K15R）をオフにする。さらに、室外側制御回路（13）がリレー（K13R）のノーマルクローズ接点と可動接点とが接続された状態にすることで、第２室外側電源回路（12）への電力供給が遮断される（図１参照）。また、電力供給の遮断前に、室外機（10）は室内機（20）へ遮断実施信号を送信し、室内機（20）はリモコン（30）へ遮断実施信号を送信する。 In the outdoor unit (10), when the outdoor unit transmission circuit (11) receives the cutoff request signal, the outdoor control circuit (13) turns off the relay (K14R) and the relay (K15R). Furthermore, when the outdoor control circuit (13) sets the normally closed contact and the movable contact of the relay (K13R) to be connected, the power supply to the second outdoor power supply circuit (12) is cut off ( (See FIG. 1). Further, before the power supply is cut off, the outdoor unit (10) transmits a cut-off execution signal to the indoor unit (20), and the indoor unit (20) transmits a cut-off execution signal to the remote controller (30).
　　リモコン（30）では、通信部（33）が遮断実施信号を受信すると、制御部（40）が遮断部（35）の２つのリレー（36,37）をオフにする。これにより、電力供給部（32）から表示部（34）及び通信部（33）への電力供給が遮断される（図２参照）。こうして、サスペンド状態への移行が完了する。 In the remote controller (30), when the communication unit (33) receives the cutoff execution signal, the control unit (40) turns off the two relays (36, 37) of the cutoff unit (35). Thereby, the power supply from the power supply unit (32) to the display unit (34) and the communication unit (33) is cut off (see FIG. 2). Thus, the transition to the suspended state is completed.
