図１に基づいて本発明の家屋の電源装置を説明する。図１には本発明の一実施例に係る家屋の電源装置の全体システムを説明するための概略状況を示してある。   A power supply device for a house according to the present invention will be described with reference to FIG. FIG. 1 shows a schematic situation for explaining an entire system of a power supply device for a house according to an embodiment of the present invention.

図に示すように、家屋１には電力会社からの商用電力（電力）が電線２を介して受電部３に供給され、受電部３に供給された電力は分電部４から電気負荷（家電装置や照明装置等）５に供給される。一方、家屋１には戸別電源装置６が備えられ、戸別電源装置６から電気負荷５に電力の供給が可能になっている。   As shown in the drawing, commercial power (electric power) from an electric power company is supplied to the power receiving unit 3 through the electric wire 2 in the house 1, and the electric power supplied to the power receiving unit 3 is supplied from the power distribution unit 4 to an electric load (home appliance). Device, lighting device, etc.) 5. On the other hand, the house 1 is provided with a door-to-door power supply 6, and power can be supplied from the door-to-door power supply 6 to the electric load 5.

戸別電源装置６には蓄電池１１が備えられ、蓄電池１１は分電部４から電力が供給されて充電される。分電部４からの電力は電力会社から供給される電力であり、蓄電池１１には料金が安い、例えば、深夜電力が供給されて充電される。また、家屋１には家屋用発電手段としての太陽光発電装置１２が備えられ、太陽光発電装置１２で得られた電力が蓄電池１１に供給されて充電される。   The door-to-door power supply device 6 includes a storage battery 11, and the storage battery 11 is supplied with power from the power distribution unit 4 and is charged. The power from the power distribution unit 4 is supplied from an electric power company, and the storage battery 11 is charged with a low charge, for example, midnight power is supplied and charged. Further, the house 1 is provided with a solar power generation device 12 as a power generation means for the house, and the electric power obtained by the solar power generation device 12 is supplied to the storage battery 11 and charged.

家屋用発電手段としては、太陽光以外の自然エネルギーにより発電を行う設備や、家庭用燃料電池、家庭用マイクロタービン等の発電設備が適用される。   As the power generation means for houses, facilities for generating power using natural energy other than sunlight, and power generation facilities such as household fuel cells and household micro turbines are applied.

戸別電源装置６には遮断手段としてのブレーカ１３が備えられ、蓄電池１１に充電された電力はブレーカ１３を介して電気負荷５に供給される。例えば、料金の安い深夜電力や太陽光発電装置１２で得られた電力が充電された状態で、昼間の電気負荷５の電力が蓄電池１１から供給され、実質的に深夜電力の料金以下のコストで昼間の電力を賄うことができる。   The door-to-door power supply device 6 is provided with a breaker 13 as a shut-off means, and the electric power charged in the storage battery 11 is supplied to the electric load 5 through the breaker 13. For example, in the state where the low-price midnight power or the power obtained by the solar power generation device 12 is charged, the power of the daytime electric load 5 is supplied from the storage battery 11 and is substantially less than the midnight power charge. Can cover daytime power.

一方、戸別電源装置６には電気動力の車両１４が接続可能とされ、車両１４に対して蓄電池１１の電力が充電可能になっている。車両１４は、電動モータにより駆動力を得る電気自動車であり、駐車時に蓄電池１１の電力が車載蓄電池１５に供給されて車載蓄電池１５が充電される。車両としては、動力源としてエンジンと電動モータとを有するハイブリッド車両を用いることも可能である。   On the other hand, the vehicle-powered vehicle 14 can be connected to the door-to-door power supply device 6, and the power of the storage battery 11 can be charged to the vehicle 14. The vehicle 14 is an electric vehicle that obtains a driving force by an electric motor, and the electric power of the storage battery 11 is supplied to the in-vehicle storage battery 15 during parking so that the in-vehicle storage battery 15 is charged. As the vehicle, it is also possible to use a hybrid vehicle having an engine and an electric motor as power sources.

尚、蓄電池１１の電力により車両１４の車載蓄電池１５の充電を行う例を挙げて説明したが、車両１４を接続した際に太陽光発電装置１２で得られた電力及び分電部４からの電力により車載蓄電池１５の充電を行うことも可能である。そして、蓄電池１１とは並列に、もしくは、蓄電池１１の電力と合わせて電気負荷５に供給する構成にすることも可能である。   In addition, although the example which charges the vehicle-mounted storage battery 15 of the vehicle 14 with the electric power of the storage battery 11 was given and demonstrated, the electric power obtained by the solar power generation device 12 when the vehicle 14 was connected, and the electric power from the power distribution part 4 Thus, it is possible to charge the in-vehicle storage battery 15. And it is also possible to make it the structure supplied to the electric load 5 in parallel with the storage battery 11 or together with the electric power of the storage battery 11.

家屋１には火災検知器としての火災報知器２１が設置され、火災報知器２１には温度検出手段２２が備えられている。戸別電源装置６には制御手段２３が備えられ、火災報知器２１の検知情報及び火災が検知された際に温度検出手段２２で検出される温度情報が制御手段２３に送られる。また、家屋１には表示手段としての警報ランプ２４が備えられ、警報ランプ２４は戸別電源装置６の蓄電池１１の電力により動作する。   The house 1 is provided with a fire alarm 21 as a fire detector, and the fire alarm 21 is provided with temperature detection means 22. The door-to-door power supply 6 is provided with a control means 23, and the detection information of the fire alarm 21 and the temperature information detected by the temperature detection means 22 when a fire is detected are sent to the control means 23. Further, the house 1 is provided with an alarm lamp 24 as display means, and the alarm lamp 24 is operated by the power of the storage battery 11 of the door-to-door power supply device 6.

火災の情報が制御手段２３に入力されると、制御手段２３はブレーカ１３を遮断して蓄電池１１から電気負荷５への電力の供給を遮断し、同時に、蓄電池１１の電力により警報ランプ２４を動作させる。また、火災発生時に戸別電源装置６に車両１４が接続されていた場合、制御手段２３は車両１４のハザードランプ２６を点滅させる。更に、ヘッドランプ２７を点滅させ、警音機器（クラクション）を作動させて車両１４から警報音を発生させる。   When the fire information is input to the control means 23, the control means 23 shuts off the breaker 13 to cut off the power supply from the storage battery 11 to the electric load 5, and at the same time operates the alarm lamp 24 with the power of the storage battery 11. Let Further, when the vehicle 14 is connected to the door-to-door power supply device 6 when a fire occurs, the control means 23 causes the hazard lamp 26 of the vehicle 14 to blink. Further, the headlamp 27 is blinked, and a warning sound device (horn) is operated to generate a warning sound from the vehicle 14.

火災発生時に車両１４が接続されてハザードランプ２６を点滅させた場合、ヘッドランプ２７を点滅させた場合、警音機器（クラクション）を作動させて車両１４から警報音を発生させた場合、動作後に、蓄電池１１と車両１４の接続を強制的に遮断させることが好適である。火災発生時に蓄電池１１と車両１４の接続を強制的に遮断させることで、接続配線の破損が防止され、火災による車両１４に対する悪影響をなくすことができる。   When the vehicle 14 is connected and the hazard lamp 26 is blinked in the event of a fire, the headlamp 27 is blinked, the alarm device (horn) is activated and an alarm sound is generated from the vehicle 14, after the operation It is preferable to forcibly cut off the connection between the storage battery 11 and the vehicle 14. By forcibly blocking the connection between the storage battery 11 and the vehicle 14 when a fire occurs, the connection wiring is prevented from being damaged, and the adverse effect on the vehicle 14 due to the fire can be eliminated.

上記構成の家屋の電源装置では、電力会社から供給される電力のうち、低料金の深夜電力等が蓄電池１１に充電される。また、太陽光発電装置１２で発電された電力が蓄電池１１に充電される。蓄電池１１に充電された電力は、家屋１の電気負荷５の昼間の電力源として供給されたり、家屋１が停電した際のバックアップの電力として供給される。また、車両１４が接続されると、蓄電池１１の電力が車載蓄電池１５に充電され、車両１４の動力エネルギーが蓄えられる。   In the power supply device for a house having the above-described configuration, low-power late-night power or the like is charged to the storage battery 11 among the power supplied from the power company. In addition, the storage battery 11 is charged with the power generated by the solar power generation device 12. The electric power charged in the storage battery 11 is supplied as a daytime electric power source of the electric load 5 of the house 1 or supplied as backup electric power when the house 1 has a power failure. Further, when the vehicle 14 is connected, the electric power of the storage battery 11 is charged in the in-vehicle storage battery 15 and the motive energy of the vehicle 14 is stored.

蓄電池１１から電気負荷５に電力が供給されている状態で、火災報知器２１により火災の発生が検知された場合、火災報知器２１の火災検知情報が制御手段２３に送られる。火災発生の情報が火災報知器２１から制御手段２３に送られると、ブレーカ１３が遮断されて蓄電池１１から電気負荷５への電力の供給が遮断される。同時に、蓄電池１１の電力により警報ランプ２４が点灯され、外部に火災の発生が知らされる（表示される）。   When fire is detected by the fire alarm 21 in a state where electric power is supplied from the storage battery 11 to the electric load 5, the fire detection information of the fire alarm 21 is sent to the control means 23. When the information on the occurrence of a fire is sent from the fire alarm 21 to the control means 23, the breaker 13 is cut off, and the supply of electric power from the storage battery 11 to the electric load 5 is cut off. At the same time, the alarm lamp 24 is turned on by the power of the storage battery 11, and the occurrence of a fire is notified (displayed) to the outside.

また、火災発生時に戸別電源装置６に車両１４が接続されていた場合、制御手段２３は車両１４のハザードランプ２６を点滅させ、更に、ヘッドランプ２７を点滅させる。火災の状況により、制御手段２３により警音機器（クラクション）を作動させて車両１４から音により火災の発生を表示する。   If the vehicle 14 is connected to the door-to-door power supply 6 when a fire occurs, the control means 23 causes the hazard lamp 26 of the vehicle 14 to blink, and further causes the head lamp 27 to blink. Depending on the situation of the fire, the control means 23 activates a warning sound device (horn) and displays the occurrence of the fire by sound from the vehicle 14.

警報ランプ２４の点灯、ハザードランプ２６の点滅、ヘッドランプ２７の点滅、クラクションの作動は、全てを同時に実施することが可能である。また、温度検出手段２２からの温度情報により火災の状態をレベル分けし、火災のレベルに応じて警報の種類を使い分けることができる。   The lighting of the alarm lamp 24, the blinking of the hazard lamp 26, the blinking of the headlamp 27, and the operation of the horn can all be performed simultaneously. Further, the state of the fire can be classified into levels based on the temperature information from the temperature detection means 22, and the type of alarm can be used properly according to the level of the fire.

上述した家屋の電源装置は、火災報知器２１により火災発生が検知された場合、ブレーカ１３を遮断して蓄電池１１から電気負荷５への電力の供給を遮断する。このため、蓄電池１１により電力が供給されている際に火災が発生した際、蓄電池１１からの電力の供給を速やかに停止し、配線損傷による短絡等の２次被害を防止することができる。   When the fire alarm 21 detects the occurrence of a fire, the house power supply device described above shuts off the breaker 13 and shuts off the supply of power from the storage battery 11 to the electrical load 5. For this reason, when a fire occurs when electric power is supplied from the storage battery 11, the supply of electric power from the storage battery 11 can be quickly stopped, and secondary damage such as a short circuit due to wiring damage can be prevented.

同時に、火災報知器２１により火災発生が検知された場合、蓄電池１１の電力により警報ランプ２４を点灯させ、車両１４のハザードランプ２６、ヘッドランプ２７を点滅させ、クラクションを作動させるので、火災の発生を確実に外部に表示することができる。   At the same time, when a fire occurrence is detected by the fire alarm 21, the alarm lamp 24 is turned on by the power of the storage battery 11, the hazard lamp 26 and the headlamp 27 of the vehicle 14 are blinked, and the horn is activated. Can be reliably displayed outside.

従って、火災発生時に蓄電池１１からの電力の供給を速やかに遮断して安全性を確保し、火災の発生を確実に外部に表示することが可能になる。   Therefore, it is possible to quickly shut off the supply of power from the storage battery 11 in the event of a fire to ensure safety and to reliably display the occurrence of the fire to the outside.

図２に基づいて家屋の電源装置の他の実施例を説明する。図２には本発明の他の実施例に係る家屋の電源装置の戸別電源装置の概略構成を示してある。尚、図１に示した構成部材と同一部材には同一符号を付して重複する説明は省略してある。   Another embodiment of the power supply device for a house will be described with reference to FIG. FIG. 2 shows a schematic configuration of a door-to-door power supply device for a house power supply device according to another embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same member as the structural member shown in FIG. 1, and the overlapping description is abbreviate | omitted.

図２に示すように、戸別電源装置３１にはブレーカ１３及び制御手段２３が備えられ、制御手段２３には火災報知器２１の情報が入力される。戸別電源装置３１には車両１４が接続可能とされ、車両１４が接続された際にブレーカ１３を介して車載蓄電池１５の電力が電気負荷５に供給される。そして、図示しない分電機能により、車載蓄電池１５の電力が戸別電源装置３１を介して警報ランプ２４に送られる。   As shown in FIG. 2, the door-to-door power supply device 31 includes a breaker 13 and a control unit 23, and information on the fire alarm 21 is input to the control unit 23. The vehicle 14 can be connected to the door-to-door power supply 31, and the electric power of the in-vehicle storage battery 15 is supplied to the electric load 5 via the breaker 13 when the vehicle 14 is connected. And the electric power of the vehicle-mounted storage battery 15 is sent to the alarm lamp 24 via the door-to-door power supply device 31 by a power distribution function (not shown).

また、戸別電源装置３１には図示しない受電部が備えられ、太陽光発電装置１２及び分電部４からの電力が供給される。供給された電力は、車両１４が接続された際に車載蓄電池１５に充電される。図２に示した実施例は、車両１４が接続された際に車載蓄電池１５が戸別電源装置３１の蓄電池を兼用する構成となっている。このため、戸別電源装置３１に蓄電池を備えることなく、電気負荷５に電力を供給することができる。   In addition, the door-to-door power supply device 31 is provided with a power reception unit (not shown), and is supplied with power from the solar power generation device 12 and the power distribution unit 4. The supplied power is charged into the in-vehicle storage battery 15 when the vehicle 14 is connected. In the embodiment shown in FIG. 2, when the vehicle 14 is connected, the in-vehicle storage battery 15 also serves as the storage battery of the door-to-door power supply 31. For this reason, electric power can be supplied to the electric load 5 without providing the storage battery in the door-to-door power supply device 31.

従って、火災発生の情報が火災報知器２１から制御手段２３に送られると、ブレーカ１３が遮断されて車載蓄電池１５から電気負荷５への電力の供給が遮断され、配線損傷による短絡等の２次被害を防止することができる。同時に、車載蓄電池１５の電力により警報ランプ２４が点灯され、外部に火災の発生が知らされ、車両１４のハザードランプ２６、ヘッドランプ２７が点滅され、クラクションが作動され、火災の発生を確実に外部に表示することができる。   Therefore, when information on the occurrence of a fire is sent from the fire alarm 21 to the control means 23, the breaker 13 is cut off, the supply of electric power from the in-vehicle storage battery 15 to the electric load 5 is cut off, and a secondary such as a short circuit due to wiring damage. Damage can be prevented. At the same time, the alarm lamp 24 is turned on by the electric power of the in-vehicle storage battery 15, the occurrence of a fire is notified to the outside, the hazard lamp 26 and the headlamp 27 of the vehicle 14 are blinked, the horn is activated, and the occurrence of the fire is reliably Can be displayed.
