図7は、従来の空気調和機の構成図である。   FIG. 7 is a configuration diagram of a conventional air conditioner.

図7において、従来の空気調和機は、制御部32と通信手段34と電源部33を備え商用電源35と接続される室外機31と、制御部39と通信手段37と電源部38を備えた室内機36から構成され、室外機31と室内機36は、室内外接続線40にて接続されている。   In FIG. 7, the conventional air conditioner includes an outdoor unit 31 that includes a control unit 32, a communication unit 34, and a power supply unit 33 and is connected to a commercial power supply 35, a control unit 39, a communication unit 37, and a power supply unit 38.

特開平6−147616号公報JP-A-6-147616

しかしながら前記従来の空気調和機の構成では、商用交流電源の供給が室外機31であっても、リモコン41からの信号を受信するため室内機36の制御部39を動作させる電力と、室外機31への通信信号の伝達を行う通信手段37を動作させる電力が必要である。そのため運転停止時であっても、室外機31の制御部32が動作するための電力と、室外機31の通信手段34が動作するための電力と、室内機36の制御部39が動作するための電力と、室内機36の通信手段37が動作するための電力を常に供給する必要があり、空気調和機の運転停止時の待機電力消費量が多くなるという課題を有していた。   However, in the configuration of the conventional air conditioner, even when the commercial AC power is supplied from the outdoor unit 31, the power for operating the control unit 39 of the indoor unit 36 to receive the signal from the remote controller 41, and the outdoor unit 31. Electric power is required to operate the communication means 37 that transmits the communication signal. Therefore, even when the operation is stopped, power for operating the control unit 32 of the outdoor unit 31, power for operating the communication means 34 of the outdoor unit 31, and control unit 39 of the indoor unit 36 operate. Power and power for operating the communication means 37 of the indoor unit 36 need to be constantly supplied, and the standby power consumption when the operation of the air conditioner is stopped increases.

本発明は、前記従来の課題を解決するもので、商用交流電源を室外機へ供給し、室外機から室内機にリモコン信号受信や通信伝達のための電力を供給している空気調和機において、空気調和機の快適性や利便性を損なうことなく、また生産コストを増大させることなく、運転停止時の待機電力消費量を削減することができる空気調和機を提供することを目的とする。   The present invention solves the above-described conventional problems, in an air conditioner that supplies commercial AC power to an outdoor unit and supplies power for remote control signal reception and communication transmission from the outdoor unit to the indoor unit. It is an object of the present invention to provide an air conditioner capable of reducing standby power consumption when operation is stopped without impairing the comfort and convenience of the air conditioner and without increasing production costs.

上記従来の課題を解決する為に、本発明の空気調和機は、室内機電源部と室内機制御部と室内機通信手段を備えた室内機と、室外機電源部と室外機制御部と室外機通信手段を備えた室外機とから構成され、前記室外機へ商用交流電源を接続すると共に、室内外接続線A、Bを通して前記室内機へ電力の供給を行い、前記室外機通信手段と前記室内機通信手段との間の信号伝達を前記室内外接続線B、Cを通して行う空気調和機において、前記室内外接続線に、前記室内機電源部への電力供給を切り換える電源切換手段を設け、前記空気調和機の運転停止時に、前記室内機制御部に供給される制御電圧を検知する低電圧検出手段を設け、前記低電圧検出手段で検出された電圧に応じて前記電源切換手段をON/OFFするものであって、前記電源切換手段がOFFのときに、前記室内機制御部が通信データを受信した場合、前記室内機制御部で前記通信データを記憶し、前記電源切換手段がONした後、室外機通信手段と室内機通信手段との間での前記通信データを伝達するものである。 In order to solve the above-described conventional problems, an air conditioner of the present invention includes an indoor unit power supply unit, an indoor unit control unit, an indoor unit provided with an indoor unit communication means, an outdoor unit power supply unit, an outdoor unit control unit, and an outdoor unit. An outdoor unit provided with an outdoor unit, and a commercial AC power source is connected to the outdoor unit, and power is supplied to the indoor unit through indoor and outdoor connection lines A and B. In the air conditioner that performs signal transmission with the indoor unit communication means through the indoor / outdoor connection lines B and C, the indoor / outdoor connection line B is provided with a power supply switching means for switching power supply to the indoor unit power supply unit. And a low voltage detecting means for detecting a control voltage supplied to the indoor unit controller when the operation of the air conditioner is stopped, and the power supply switching means is turned on according to the voltage detected by the low voltage detecting means. / it is one that OFF, the When the indoor unit control unit receives communication data when the source switching unit is OFF, the indoor unit control unit stores the communication data, and after the power source switching unit is turned ON, the outdoor unit communication unit and the indoor unit control unit The communication data is transmitted to and from the machine communication means.

本発明の空気調和機は、室内機への電力供給が遮断された後も室内機電源部に充電された電荷の分だけ継続して室内機制御部や室内機通信手段を動作させることが可能となり、室内機電源部に充電された電荷が既定値を下回った場合は、低電圧検出手段により再び室内機の判断手段により電源切換手段をオンして室内機電源部に充電を行うので、室内機への電力供給を常時行う必要がなくなり、運転停止時の待機電力を削減する効果がありCO排出の抑制を図れる。 The air conditioner of the present invention can continuously operate the indoor unit control unit and the indoor unit communication means by the amount of charge charged in the indoor unit power supply unit even after the power supply to the indoor unit is interrupted.

第1の発明は、室内機電源部と室内機制御部と室内機通信手段を備えた室内機と、室外機電源部と室外機制御部と室外機通信手段を備えた室外機とから構成され、前記室外機へ商用交流電源を接続すると共に、室内外接続線A、Bを通して前記室内機へ電力の供給を行い、前記室外機通信手段と前記室内機通信手段との間の信号伝達を前記室内外接続線B、Cを通して行う空気調和機において、前記室内外接続線に、前記室内機電源部への電力供給を切り換える電源切換手段を設け、前記空気調和機の運転停止時に、前記室内機制御部に供給される制御電圧を検知する低電圧検出手段を設け、前記低電圧検出手段で検出された電圧に応じて前記電源切換手段をON/OFFするものであって、前記電源切換手段がOFFのときに、前記室内機制御部が通信データを受信した場合、前記室内機制御部で前記通信データを記憶し、前記電源切換手段がONした後、室外機通信手段と室内機通信手段との間での前記通信データを伝達するものである。 The first invention includes an indoor unit provided with an indoor unit power supply unit, an indoor unit control unit, and an indoor unit communication means, and an outdoor unit provided with an outdoor unit power supply unit, an outdoor unit control unit, and an outdoor unit communication means. , Connecting a commercial AC power source to the outdoor unit, supplying power to the indoor unit through indoor and outdoor connection lines A and B, and transmitting signals between the outdoor unit communication means and the indoor unit communication means. In the air conditioner performed through the indoor / outdoor connection lines B and C, the indoor / outdoor connection line B is provided with power supply switching means for switching power supply to the indoor unit power supply unit, and when the operation of the air conditioner is stopped, A low voltage detecting means for detecting a control voltage supplied to the machine control section, and the power supply switching means is turned on / off according to the voltage detected by the low voltage detecting means; When the room is off When the control unit receives communication data, the indoor unit control unit stores the communication data, and after the power supply switching unit is turned on, the communication data between the outdoor unit communication unit and the indoor unit communication unit is stored. To communicate.

の発明では、空気調和機の運転停止時は、室内電源部の電圧を低電圧検出手段により監視し、電圧が動作を継続出来ないレベルまで低下した場合、電源切換手段を任意の時間だけオンし室内機への電力供給回路及びデータ通信回路を成立させる。電力供給回路及びデータ通信回路の成立により前記室内機電源部において交流電力から直流電力に変換された電荷が充電され、室内機制御部と室内機通信手段が動作を開始し、室外機通信手段と前記室内機制御部と室内機通信手段の間で通信が成立する。室外機の判断手段により電源切換手段がオフし室内機への電力供給回路とデータ通信回路が不成立となった後も、前記室内機電源部に充電された電荷の分だけ室内機制御部は動作を継続するため、リモコンより送信される信号データの受信を可能とする。室内機制御部では、リモコンより送信された信号データを一時的に記憶する。室内機電源部の電荷が消費され、電荷量が減少し室内機制御部が動作を停止する前に再び室外機の判断手段により電源切換手段をオンし、室内機への電力供給回路及びデータ通信回路を成立させる。この時室内機制御部で記憶していた信号データを、室内機通信手段を通して室外機通信手段から室外機制御部へ伝達され室外機は動作を行う。室内機側の判断手段により電源切換手段のオンとオフを繰り返し、電力供給回路及びデータ通信回路を閉回路と開回路を繰り返し成立することにより、前記室内機電源部に充電される電荷量を常に既定値以上に保つことができ室内機制御部の動作を継続することができる。また充電された電荷を消費するのが室内機制御部のみであるため充電された電荷の減少する時間が遅く、電源切換手段のオフの時間を長く設定することができる。そのため室内機への電力供給を常時行うことなく、室内機制御部を長く動作できるので空気調和機の運転停止時の待機電力をより多く低減することができる。 In the first invention, during the operation stop of the air conditioner, the voltage of the indoor power supply unit is monitored by a low voltage detection means, when reduced to a level where the voltage can not continue the operation, any time a power supply switching means The power supply circuit and the data communication circuit for the indoor unit are established. Due to the establishment of the power supply circuit and the data communication circuit, the electric charge converted from AC power to DC power is charged in the indoor unit power supply unit, the indoor unit control unit and the indoor unit communication unit start operating, and the outdoor unit communication unit Communication is established between the indoor unit controller and the indoor unit communication means. Even after the power supply switching means is turned off by the judgment unit of the outdoor unit and the power supply circuit and the data communication circuit to the indoor unit are not established, the indoor unit control unit operates by the amount of charge charged in the indoor unit power supply unit. Therefore, it is possible to receive the signal data transmitted from the remote controller. The indoor unit control unit temporarily stores the signal data transmitted from the remote controller. The electric power of the indoor unit power supply unit is consumed, the amount of electric charge is reduced, and the indoor unit control unit stops the operation before turning on the power supply switching unit by the judgment unit of the outdoor unit, and the power supply circuit and data communication to the indoor unit Establish a circuit. At this time, the signal data stored in the indoor unit control unit is transmitted from the outdoor unit communication unit to the outdoor unit control unit through the indoor unit communication unit, and the outdoor unit operates. The determination unit on the indoor unit side repeatedly turns on and off the power supply switching unit, and the power supply circuit and the data communication circuit are repeatedly closed and opened so that the amount of electric charge charged in the indoor unit power supply unit is always maintained. It can be kept above the predetermined value, and the operation of the indoor unit control unit can be continued. Further, since only the indoor unit control unit consumes the charged electric charge, the time for reducing the charged electric charge is slow, and the time for turning off the power supply switching means can be set longer. Therefore, since the indoor unit control unit can be operated for a long time without always supplying power to the indoor unit, standby power when the operation of the air conditioner is stopped can be further reduced.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

In FIG. 1, the air conditioner according to the present embodiment includes a single outdoor unit 1 and a plurality of indoor units A6a, indoor units B6b, indoor units C6c, and indoor units D6d connected to the outdoor unit 1. ing.

室外機1は、室外機制御部2と、室外機電源部3と、室外機通信手段4を備え、商用交流電源5に接続されている。室内機A6a(室内機B6b、室内機C6c、室内機D6dも同じ、以下同じ)は、室内機通信手段7と、室内機電源部8と、室内機制御部9と、電源切換手段14と、室内機電源部8のトランス15と、室内機電源部8の電解コンデンサ16と、室内機電源部8の定電圧電源17と、室内機制御部9のマイクロコンピューター18(以下、「マイコン18と呼ぶ)と、室内機電源部8のダイオードブリッジ19と、室内機通信手段7の通信カプラ20を有している。室外機1の室外機制御部2は、判断手段25を有している。   The outdoor unit 1 includes an outdoor unit control unit 2, an outdoor unit power supply unit 3, and an outdoor unit communication unit 4, and is connected to a commercial AC power source 5. The indoor unit A6a (the indoor unit B6b, the indoor unit C6c, and the indoor unit D6d are also the same), the indoor unit communication means 7, the indoor unit power supply unit 8, the indoor unit control unit 9, the power supply switching unit 14, The transformer 15 of the indoor unit power supply unit 8, the electrolytic capacitor 16 of the indoor unit power supply unit 8, the constant voltage power supply 17 of the indoor unit power supply unit 8, and the microcomputer 18 of the indoor unit control unit 9 (hereinafter referred to as "microcomputer 18"). ), A diode bridge 19 of the indoor unit power supply unit 8, and a communication coupler 20 of the indoor unit communication unit 7. The outdoor unit control unit 2 of the outdoor unit 1 includes a determination unit 25.

室外機1と室内機A6aとは、室内外接続線A11と、室内外接続線B12と、室内外接続線C13で電気的に接続されると共に、両者の運転操作は、リモコン10で行われる。   The outdoor unit 1 and the indoor unit A6a are electrically connected by an indoor / outdoor connection line A11, an indoor / outdoor connection line B12, and an indoor / outdoor connection line C13, and the driving operation of both is performed by the remote controller 10.

以上のように構成された本実施の形態における空気調和機のその動作、作用について以下に説明する。   The operation and action of the air conditioner in the present embodiment configured as described above will be described below.

商用交流電源5に接続された室外機1は、室内外接続線A11と同ライン上に設けた電源切換手段14と、室内外接続線A11、B12を通して、室内機A6aの室内機電源部8へ電力供給を行う。室内機電源部8は、ダイオードブリッジ19と、トランス15にて交流電力を直流電力に変換したNR電力を出力する。   The outdoor unit 1 connected to the commercial AC power source 5 passes through the power source switching means 14 provided on the same line as the indoor / outdoor connection line A11 and the indoor / outdoor connection lines A11 and B12 to the indoor unit power supply unit 8 of the indoor unit A6a. Supply power. The indoor unit power supply unit 8 outputs NR power obtained by converting AC power into DC power by the diode bridge 19 and the transformer 15.

NR電力は、定電圧電源17に入力されマイコン18や通信用カプラ動作用の5V電力を出力し、室内機制御部9のマイコン18と室内機通信手段7の通信カプラ20を動作させる。   The NR power is input to the constant voltage power supply 17 and outputs 5V power for operating the microcomputer 18 and the communication coupler to operate the microcomputer 18 of the indoor unit controller 9 and the communication coupler 20 of the indoor unit communication means 7.

室外機制御部2は、室外機通信手段4と室内外接続線B12、C13と室内機通信手段7を通して室内機制御部9と運転情報などのデータ伝達を行う。空気調和機の運転停止時は、室内機制御部9により電源切換手段14をオンし、室内機電源部8に電力を供給する。室内機電源部8の電圧を低電圧検出手段21により監視し、十分電圧が上昇すれば低電圧検出手段21により電源切換手段14をオフする。   The outdoor unit control unit 2 transmits data such as operation information to the indoor unit control unit 9 through the outdoor unit communication unit 4, the indoor / outdoor connection lines B12 and C13, and the indoor unit communication unit 7. When the operation of the air conditioner is stopped, the power switch 14 is turned on by the indoor unit controller 9 to supply power to the indoor unit power unit 8. The voltage of the indoor unit power supply unit 8 is monitored by the low voltage detection means 21, and when the voltage rises sufficiently, the power supply switching means 14 is turned off by the low voltage detection means 21.

室内機制御部9と室内機通信手段7は、室内機電源部8に供給され電解コンデンサ16にて充電された電荷の分だけNR電力を出力し、定電圧電源17により5V電力が出力されるため動作を行う。   The indoor unit control unit 9 and the indoor unit communication means 7 output NR power by the amount of electric charge supplied to the indoor unit power supply unit 8 and charged by the electrolytic capacitor 16, and 5V power is output from the constant voltage power source 17. So do the operation.

この時、室内機制御部9において、リモコン10からの運転開始などの信号を受信した場合、即座に室内機通信手段7と室内外接続線B12、C13と室外機通信手段4を通して室外機制御部2へ信号データの伝達を行うとともに、判断手段25により電源切換手段14をオンする。   At this time, when the indoor unit controller 9 receives a signal such as the start of operation from the remote controller 10, the outdoor unit controller immediately passes through the indoor unit communication means 7, the indoor / outdoor connection lines B 12 and C 13, and the outdoor unit communication means 4. The signal data is transmitted to 2 and the power supply switching means 14 is turned on by the judging means 25.

図3に示すとおり、室内機電源部8に供給され電解コンデンサ16にて充電されたNR電力は、室内機制御部9と室内機通信手段7の動作により減少する。定電圧電源17の動作に必要なNR電力を下回る前に、低電圧検出手段21により電圧低下を検知し、室内機制御部9と室内機通信手段7が動作停止する前に、室内機制御部9により電源切換手段14をオンするようシステムの構築を行う。   As shown in FIG. 3, the NR power supplied to the indoor unit power supply unit 8 and charged by the electrolytic capacitor 16 is reduced by the operations of the indoor unit control unit 9 and the indoor unit communication means 7. Before the NR power required for the operation of the constant voltage power supply 17 falls below, the low voltage detection means 21 detects a voltage drop, and before the indoor unit control unit 9 and the indoor unit communication unit 7 stop operating, the indoor unit control unit 9, the system is constructed so that the power supply switching means 14 is turned on.

室内機制御部9により電源切換手段14をオンすることにより室内機電源部8に再び電力が供給され電解コンデンサ16にてNR電力が充電され、定電圧電源17の動作が継続
し5V電力が出力されるため、室内機制御部9と室内機通信手段7は継続して動作を行うことができる。
By turning on the power source switching means 14 by the indoor unit control unit 9, the electric power is supplied again to the indoor unit power source unit 8, and the NR power is charged by the electrolytic capacitor 16, the operation of the constant voltage power source 17 is continued, and 5V power is output. Therefore, the indoor unit control unit 9 and the indoor unit communication means 7 can continue to operate.

本発明は、室外機より電源を供給するタイプの空気調和機でも、室内機への電力供給を常時ではなく、制御部の電圧を監視しながら必要最低限に電源供給することで、使用者の快適性や利便性を損なうことなく運転停止時の待機電力の低減を図ることができる。   Even in an air conditioner of a type that supplies power from an outdoor unit, the present invention does not always supply power to the indoor unit, but supplies power to the minimum necessary while monitoring the voltage of the control unit. It is possible to reduce standby power when the operation is stopped without impairing comfort and convenience.

図4及び図5は、本発明の第1の実施の形態における空気調和機の構成において、電源切換手段14を室内外接続線B12と同ライン上の室内機A6a側に設けた例を示す図である。   4 and 5 are diagrams showing an example in which the power supply switching unit 14 is provided on the indoor unit A6a side on the same line as the indoor / outdoor connection line B12 in the configuration of the air conditioner according to the first embodiment of the present invention. It is.

空気調和機の運転停止時は、室内機A6aの室内機制御部9により電源切換手段14をオンし、室内機A6aの室内機電源部8に電力を供給する。室内機電源部8の電圧を低電圧検出手段21により監視し、十分電圧が上昇すれば、室内機制御部9により電源切換手段14をオフする。   When the operation of the air conditioner is stopped, the power supply switching means 14 is turned on by the indoor unit control unit 9 of the indoor unit A6a, and power is supplied to the indoor unit power supply unit 8 of the indoor unit A6a. The voltage of the indoor unit power supply unit 8 is monitored by the low voltage detection means 21, and when the voltage rises sufficiently, the indoor unit control unit 9 turns off the power supply switching means 14.

これにより室内機A6aの室内機通信手段7は動作を停止することになる。これにより室内機通信手段7で消費されていた電力はゼロとなる。室内機制御部9は、室内機電源部8に供給され電解コンデンサ16にて充電された電荷の分だけNR電力を出力し、定電圧電源17により5V電力が出力されるため動作を行う。   As a result, the indoor unit communication means 7 of the indoor unit A6a stops operating. As a result, the power consumed by the indoor unit communication means 7 becomes zero. The indoor unit control unit 9 outputs NR power corresponding to the charge supplied to the indoor unit power supply unit 8 and charged by the electrolytic capacitor 16, and operates because 5 V power is output from the constant voltage power supply 17.

この時、室内機A6aの室内機制御部9においてリモコン10からの運転開始などの信号を受信した場合、室内機制御部9のマイコン18でその信号情報を一時記憶する。図5に示すとおり、室内機A6aの室内機電源部8に供給され電解コンデンサ16にて充電されたNR電力は、室内機制御部9の動作により減少する。   At this time, when the indoor unit control unit 9 of the indoor unit A6a receives a signal such as an operation start from the remote controller 10, the microcomputer 18 of the indoor unit control unit 9 temporarily stores the signal information. As shown in FIG. 5, the NR power supplied to the indoor unit power supply unit 8 of the indoor unit A 6 a and charged by the electrolytic capacitor 16 is reduced by the operation of the indoor unit control unit 9.

定電圧電源17の動作に必要なNR電力を下回る前に、低電圧検出手段21により電圧低下を検知し、室内機制御部9の動作が停止する前に室内機A6aの室内機制御部9より電源切換手段14をオンするようシステムの構築を行う。   Before the NR power required for the operation of the constant voltage power supply 17 falls below, the low voltage detection means 21 detects a voltage drop, and before the operation of the indoor unit control unit 9 stops, the indoor unit control unit 9 of the indoor unit A6a The system is constructed so that the power supply switching means 14 is turned on.

判断手段25により電源切換手段14をオンすることにより、室内機A6aの室内機電源部8に再び電力が供給され電解コンデンサ16にてNR電力が充電され、定電圧電源17の動作が継続し5V電力が出力されるため室内機制御部9は動作を継続し、室内機通信手段7は動作を開始することができる。   When the power source switching means 14 is turned on by the judging means 25, power is again supplied to the indoor unit power supply unit 8 of the indoor unit A6a, NR power is charged by the electrolytic capacitor 16, and the operation of the constant voltage power source 17 is continued. Since electric power is output, the indoor unit control unit 9 continues to operate, and the indoor unit communication means 7 can start operation.

室内機通信手段7が動作を開始した後、室内機制御部9は、リモコン10からの運転開始などの信号データを即座に室内機通信手段7と室内外接続線B12、C13と室外機1の室外機通信手段4を通して室外機制御部2に伝達する。   After the indoor unit communication means 7 starts its operation, the indoor unit control unit 9 immediately sends signal data such as the start of operation from the remote controller 10 to the indoor unit communication means 7, the indoor / outdoor connection lines B12 and C13, and the outdoor unit 1. This is transmitted to the outdoor unit controller 2 through the outdoor unit communication means 4.

本発明は、室外機より電源を供給するタイプの空気調和機でも、室内機への電力供給を常時ではなく、制御部の電圧を監視しながら必要最低限に電源供給することで、室内機での消費電力を多く低減することで使用者の快適性や利便性を損なうことなく運転停止時の待機電力をより多く低減をすることができる。   Even in an air conditioner that supplies power from an outdoor unit, the present invention does not always supply power to the indoor unit, but supplies power to the minimum necessary while monitoring the voltage of the control unit. As a result, the standby power when the operation is stopped can be further reduced without impairing the comfort and convenience of the user.

以上のように、本発明にかかる空気調和機は、複数台の室内機を有し、室外機より電源を供給するタイプの空気調和機においても運転停止時の待機電力を低減する効果があるため、空気調和機以外にもエコ給湯機器など運転停止時にリモコンからのデータ信号受信を待機している各種電気機器にも適用できるものである。   As described above, the air conditioner according to the present invention has an effect of reducing standby power when the operation is stopped even in an air conditioner having a plurality of indoor units and supplying power from the outdoor unit. In addition to the air conditioner, the present invention can also be applied to various electric devices such as eco water heaters that are waiting to receive a data signal from the remote controller when the operation is stopped.
