（実施の形態１）
図１は、本発明の実施の形態１における家庭電気製品収納庫のブロック図を示し、図２は、同家庭電気製品収納庫の斜視図を示すものである。 (Embodiment 1)
FIG. 1 shows a block diagram of a household electrical appliance storage in Embodiment 1 of the present invention, and FIG. 2 shows a perspective view of the household electrical appliance storage.

図１および２に示すように、キャビネット１は、前面が開口した家庭電気製品収納部２を有し、この家庭電気製品収納部２に家庭電気製品（図示せず）を載置して収納するように構成している。第１の給電手段（給電手段）３および第２の給電手段（給電手段）４はコンセントにより構成し、家庭電気製品を接続して給電するもので、家庭電気製品収納部２に設けている。第１の電源制御手段（電源制御手段）１０および第２の電源制御手段（電源制御手段）１１はリレーにより構成し、それぞれ第１の給電手段３および第２の給電手段４を制御するようにしている。   As shown in FIGS. 1 and 2, the cabinet 1 has a household electrical appliance storage unit 2 having an open front, and stores and stores a household electrical appliance (not shown) in the household electrical appliance storage unit 2. It is configured as follows. The first power supply means (power supply means) 3 and the second power supply means (power supply means) 4 are constituted by outlets, and are connected to the home electric product to supply power, and are provided in the home electric product storage section 2. The first power supply control means (power supply control means) 10 and the second power supply control means (power supply control means) 11 are constituted by relays, and control the first power supply means 3 and the second power supply means 4 respectively. ing.

一酸化炭素濃度検知手段１２は、家庭電気製品収納部２の一酸化炭素濃度を検出するもので、制御手段１５は、一酸化炭素濃度検知手段１２の出力上昇率により動作するもので、家庭電気製品収納部２の一酸化炭素濃度が異常に変化した場合、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、第１の電源制御手段１０および第２の電源制御手段１１を介して、分電盤７から第１の給電手段３および第２の給電手段４への商用電源の給電を停止するよう構成している。   The carbon monoxide concentration detection means 12 detects the carbon monoxide concentration of the household electrical appliance storage unit 2, and the control means 15 operates according to the output increase rate of the carbon monoxide concentration detection means 12. When the carbon monoxide concentration in the product storage unit 2 changes abnormally, when the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level, the first power supply control means 10 and the second power supply control means 11 are used. The power supply of the commercial power source from the distribution board 7 to the first power supply means 3 and the second power supply means 4 is stopped.

表示手段５は、家庭電気製品収納庫の状態を表示し、使用者に知らせるもので、ＬＥＤやＬＣＤなどで構成し、制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、表示手段５に一酸化炭素濃度の上昇を表示するようにしている。また、報知手段６は、家庭電気製品収納庫の状態を報知し、使用者に知らせるもので、ブザーや音声を報知する装置などで構成し、制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、報知手段６により一酸化炭素濃度の上昇を報知するようにしている。   The display means 5 displays the status of the household electrical appliance storage and informs the user. The display means 5 comprises an LED, an LCD, etc., and the control means 15 increases the carbon monoxide concentration of the household electrical appliance storage section 2. When the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level, the display means 5 displays an increase in the carbon monoxide concentration. Further, the notification means 6 notifies the user of the state of the household electrical appliance storage and notifies the user. The notification means 6 includes a buzzer, a voice notification device, and the like, and the control means 15 is a part of the household electrical appliance storage unit 2. When the carbon oxide concentration increases and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level, the notification means 6 notifies the increase of the carbon monoxide concentration.

上記構成において動作を説明する。家庭電気製品収納部２には主にキッチンで使用される調理家電、例えば、ジャーポット、炊飯器、コーヒーメーカなどの家庭電気製品が収納される。これらの家庭電気製品は第１の給電手段３または第２の給電手段４に接続されたまま置かれることが多い。ジャーポットであれば保温のまま昼夜を問わず、また、使用者の在、不在を問わず、第１の給電手段３または第２の給電手段４に挿入されているのが常であり、炊飯器においても、予約炊飯や保温を考慮しても常時第１の給電手段３または第２の給電手段４に挿入されていることが多い。   The operation in the above configuration will be described. The household electric appliance storage unit 2 stores cooking appliances mainly used in the kitchen, for example, household electric appliances such as jar pots, rice cookers, and coffee makers. These home appliances are often left connected to the first power supply means 3 or the second power supply means 4. If it is a jar pot, it is usually inserted into the first power supply means 3 or the second power supply means 4 regardless of the presence or absence of the user while keeping warm, and whether the user is present or not. Even in consideration of reserved rice cooking and heat retention, the device is often inserted into the first power supply means 3 or the second power supply means 4 at all times.

ここで、これら家庭電気製品の使用中に何らかの不具合により家庭電気製品収納部２内で異常過熱が発生した場合、特に発生初期においては不完全燃焼のため一酸化炭素が多く発生する。一般的に、大気中の一酸化炭素濃度は、１ｐｐｍ以下である。   Here, when abnormal overheating occurs in the household electrical appliance storage part 2 due to some trouble during use of these household electrical appliances, a large amount of carbon monoxide is generated due to incomplete combustion, particularly in the initial stage of occurrence. Generally, the carbon monoxide concentration in the atmosphere is 1 ppm or less.

一酸化炭素濃度の上昇率は、図３に示すように、
（ｂ−ａ）／（ｔ２−ｔ１）
で求められる。ここで、ある時点での一酸化炭素濃度が１１ｐｐｍであり、１０秒前の一酸化炭素濃度が１ｐｐｍの場合、上昇率は、（１１−１）／１０＝１となり、一酸化炭素濃度の上昇率が１を超えれば異常と判断するようあらかじめ制御手段１５に規定しておけば、家庭電気製品収納庫内の家庭電気製品への給電を停止する。第１の給電手段３および第２の給電手段４には、特にジャーポットや炊飯器のような熱利用機器が接続されるため、第１の給電手段３および第２の給電手段４への給電が停止すると、接続された家庭電気製品の自己発熱が停止する。このとき、表示手段５により、一酸化炭素濃度の上昇を表示するとともに、報知手段６により一酸化炭素濃度の上昇を報知する。 As shown in FIG. 3, the rate of increase in carbon monoxide concentration is
(Ba) / (t2-t1)
Is required. Here, when the carbon monoxide concentration at a certain point is 11 ppm and the carbon monoxide concentration before 10 seconds is 1 ppm, the rate of increase is (11-1) / 10 = 1, and the carbon monoxide concentration is increased. If the control means 15 preliminarily determines that an abnormality occurs when the rate exceeds 1, power supply to the household electrical appliance in the household electrical appliance storage is stopped. Since the first power supply means 3 and the second power supply means 4 are connected to a heat utilization device such as a jar pot or a rice cooker, power is supplied to the first power supply means 3 and the second power supply means 4. When is stopped, the self-heating of the connected home appliance stops. At this time, the display means 5 displays an increase in the carbon monoxide concentration, and the notification means 6 notifies the increase in the carbon monoxide concentration.

以上のように、本実施の形態においては、制御手段１５は、家庭電気製品収納部２内の一酸化炭素濃度上昇率が一定のレベルを超えると第１の給電手段３および第２の給電手段４への給電を停止するため、キャビネット１内に収納した家庭電気製品に異常過熱などが発生した場合、一酸化炭素を発生する初期状態で家庭電気製品への給電を停止することでキャビネット１内に収納した家庭電気製品の動作を停止することができ、被害が拡大するのを防止することができる。   As described above, in the present embodiment, the control means 15 is configured such that the first power supply means 3 and the second power supply means when the rate of increase in the concentration of carbon monoxide in the household electrical appliance storage unit 2 exceeds a certain level. In order to stop the power supply to 4, if abnormal overheating occurs in the household electrical product stored in the cabinet 1, the power supply to the household electrical product is stopped in the initial state where carbon monoxide is generated. It is possible to stop the operation of the household electrical appliances stored in the storage area and prevent the damage from spreading.

また、制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると表示手段５に一酸化炭素濃度の上昇を表示するようにしたので、一酸化炭素濃度上昇率が一定のレベルを超えると、表示手段５に一酸化炭素濃度の上昇を表示することで、使用者に家庭電気製品収納部２内の異常状態を知らせることができ、速やかに異常状態の収束を図ることができる。   Further, the control means 15 increases the carbon monoxide concentration on the display means 5 when the carbon monoxide concentration of the household electrical appliance storage unit 2 rises and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level. When the rate of increase in carbon monoxide concentration exceeds a certain level, the increase in the carbon monoxide concentration is displayed on the display means 5 to indicate to the user an abnormality in the home appliance storage unit 2. The state can be notified, and the abnormal state can be quickly converged.

また、制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると報知手段６により一酸化炭素濃度の上昇を報知するようにしたので、一酸化炭素濃度上昇率が一定のレベルを超えると、報知手段６により一酸化炭素濃度の上昇を報知することで、使用者が家庭電気製品収納庫から離れた場所にいる場合においても、家庭電気製品収納部２内の異常状態を知らせることができ、速やかに異常状態の収束を図ることができる。   Further, the control means 15 increases the carbon monoxide concentration by the notification means 6 when the carbon monoxide concentration of the household electrical appliance storage unit 2 rises and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level. When the carbon monoxide concentration increase rate exceeds a certain level, the notification means 6 notifies the increase in the carbon monoxide concentration, so that the user is away from the home appliance storage. Even in the case, the abnormal state in the home appliance storage unit 2 can be notified, and the abnormal state can be quickly converged.

（実施の形態２）
図４は、本発明の実施の形態２における家庭電気製品収納庫のブロック図を示し、図５は、同家庭電気製品収納庫の斜視図を示し、図６は同家庭電気製品収納庫の断面図を示すものである。 (Embodiment 2)
4 shows a block diagram of a household electrical appliance storage in Embodiment 2 of the present invention, FIG. 5 shows a perspective view of the household electrical appliance storage, and FIG. 6 shows a cross section of the household electrical appliance storage. FIG.

図４〜図６に示すように、蒸気処理手段１４は、家庭電気製品から発生する蒸気を家庭電気製品収納部２の外へ排出するもので、キャビネット１の上部に設け、蒸気処理手段１４の蒸気受け部１６に一酸化炭素濃度を検出する一酸化炭素濃度検知手段１２を設けている。制御手段１５は、蒸気処理手段１４を制御するとともに、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、蒸気処理手段１４の動作を停止するよう構成している。他の構成は上記実施の形態１と同じであり、同一符号を付して説明を省略する。   As shown in FIGS. 4 to 6, the steam processing means 14 discharges steam generated from the household electrical appliance to the outside of the household electrical product storage unit 2, and is provided in the upper part of the cabinet 1. The vapor receiver 16 is provided with carbon monoxide concentration detection means 12 for detecting the carbon monoxide concentration. The control means 15 controls the steam treatment means 14 and, when the carbon monoxide concentration of the household electrical appliance storage unit 2 rises and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level, the steam treatment The operation of the means 14 is stopped. Other configurations are the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

上記構成において動作を説明する。家庭電気製品収納部２には主にキッチンで使用される調理家電、例えば、ジャーポット、炊飯器、コーヒーメーカなどの家庭電気製品が収納される。これらの家庭電気製品は第１の給電手段３または第２の給電手段４に接続されたまま置かれることが多い。ジャーポットであれば保温のまま昼夜を問わず、また、使用者の在、不在を問わず、第１の給電手段３または第２の給電手段４に挿入されているのが常であり、炊飯器においても、予約炊飯や保温を考慮しても常時第１の給電手段３または第２の給電手段４に挿入されていることが多い。   The operation in the above configuration will be described. The household electric appliance storage unit 2 stores cooking appliances mainly used in the kitchen, for example, household electric appliances such as jar pots, rice cookers, and coffee makers. These home appliances are often left connected to the first power supply means 3 or the second power supply means 4. If it is a jar pot, it is usually inserted into the first power supply means 3 or the second power supply means 4 regardless of the presence or absence of the user while keeping warm, and whether the user is present or not. Even in consideration of reserved rice cooking and heat retention, the device is often inserted into the first power supply means 3 or the second power supply means 4 at all times.

さらに、これらの家庭電気製品は水利用機器であり、これら家庭電気製品を使用時には蒸気が発生する。そのため、家庭電気製品収納部２の上部に、家庭電気製品から発生した蒸気を庫外に排出する蒸気処理手段１４を設けており、家庭電気製品収納部２内の空気とともに家庭電気製品から発生した蒸気を吸引し、庫外に排出する。   Furthermore, these household electric appliances are water-utilizing devices, and steam is generated when these household electric appliances are used. Therefore, the steam processing means 14 for discharging the steam generated from the home appliance to the outside of the warehouse is provided in the upper part of the home appliance storage unit 2, and the steam generated from the home appliance together with the air in the home appliance storage unit 2. Vapor is sucked and discharged out of the warehouse.

ここで、これら家庭電気製品の使用中に何らかの不具合により家庭電気製品収納部２内で異常過熱が発生した場合、特に発生初期においては不完全燃焼のため一酸化炭素が多く発生する。この場合、発生した熱により家庭電気製品収納部２内の空気は上昇気流が生じる。そこで、家庭電気製品収納部２の上部にある蒸気処理手段１４の蒸気受け部１６に一酸化炭素濃度検知手段１２を設け、一酸化炭素濃度を検出する。   Here, when abnormal overheating occurs in the household electrical appliance storage part 2 due to some trouble during use of these household electrical appliances, a large amount of carbon monoxide is generated due to incomplete combustion, particularly in the initial stage of occurrence. In this case, ascending airflow is generated in the air in the household electrical appliance storage unit 2 due to the generated heat. Therefore, the carbon monoxide concentration detecting means 12 is provided in the steam receiving portion 16 of the steam processing means 14 in the upper part of the household electrical appliance storage portion 2 to detect the carbon monoxide concentration.

一般的に、大気中の一酸化炭素濃度は、１ｐｐｍ以下である。一酸化炭素濃度の上昇率は、上記実施の形態１と同様に、
（ｂ−ａ）／（ｔ２−ｔ１）
で求められる。ここで、ある時点での一酸化炭素濃度が１１ｐｐｍであり、１０秒前の一酸化炭素濃度が１ｐｐｍの場合、上昇率は、（１１−１）／１０＝１となり、一酸化炭素濃度の上昇率が１を超えれば異常と判断するようあらかじめ制御手段１５に規定しておけば、家庭電気製品収納庫内の家庭電気製品への給電を停止する。第１の給電手段３および第２の給電手段４には、特にジャーポットや炊飯器のような熱利用機器が接続されるため、第１の給電手段３および第２の給電手段４への給電が停止すると、接続された家庭電気製品の自己発熱が停止する。このとき、表示手段５により、一酸化炭素濃度の上昇を表示するとともに、報知手段６により一酸化炭素濃度の上昇を報知する。 Generally, the carbon monoxide concentration in the atmosphere is 1 ppm or less. The rate of increase in the carbon monoxide concentration is the same as in the first embodiment.
(Ba) / (t2-t1)
Is required. Here, when the carbon monoxide concentration at a certain point is 11 ppm and the carbon monoxide concentration before 10 seconds is 1 ppm, the rate of increase is (11-1) / 10 = 1, and the carbon monoxide concentration is increased. If the control means 15 preliminarily determines that an abnormality occurs when the rate exceeds 1, power supply to the household electrical appliance in the household electrical appliance storage is stopped. Since the first power supply means 3 and the second power supply means 4 are connected to a heat utilization device such as a jar pot or a rice cooker, power is supplied to the first power supply means 3 and the second power supply means 4. When is stopped, the self-heating of the connected home appliance stops. At this time, the display means 5 displays an increase in the carbon monoxide concentration, and the notification means 6 notifies the increase in the carbon monoxide concentration.

以上のように、本実施の形態においては、家庭電気製品から発生する蒸気を家庭電気製品収納部２の外へ排出する蒸気処理手段１４を備え、制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、蒸気処理手段１４の動作を停止するよう構成したので、一酸化炭素濃度の変化を捉えやすく、家庭電気製品収納部２内に収納した家庭電気製品はその動作を停止し、当該機器が熱利用機器である場合、その自己発熱を停止するのでキャビネット１の被害拡大を防止することができる。また、一酸化炭素濃度が一定のレベルを超えると蒸気処理手段１４の動作を停止するため、家庭電気製品収納部２外からの空気の供給を抑え、異常過熱による被害の拡大を抑制することができる。   As described above, in the present embodiment, the steam processing means 14 for discharging the steam generated from the household electrical appliance to the outside of the household electrical appliance storage section 2 is provided, and the control means 15 is provided in the household electrical appliance storage section 2. Since the operation of the steam processing means 14 is stopped when the carbon monoxide concentration rises and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level, it is easy to catch the change in the carbon monoxide concentration. The household electrical product stored in the household electrical appliance storage unit 2 stops its operation, and when the device is a heat utilization device, the self-heating is stopped, so that the damage of the cabinet 1 can be prevented from spreading. Further, when the carbon monoxide concentration exceeds a certain level, the operation of the steam processing means 14 is stopped, so that the supply of air from outside the household electrical appliance storage unit 2 is suppressed and the expansion of damage due to abnormal overheating can be suppressed. it can.

また、一酸化炭素濃度検知手段１２を蒸気処理手段１４の蒸気受け部１６に設けたので、異常過熱による熱に伴う上昇気流に乗った一酸化炭素を検知しやすくすることができる。   In addition, since the carbon monoxide concentration detecting means 12 is provided in the steam receiving portion 16 of the steam processing means 14, it is possible to easily detect carbon monoxide riding on the rising air flow accompanying heat due to abnormal overheating.

なお、本実施の形態では、一酸化炭素濃度検知手段１２を蒸気処理手段１４の蒸気受け部１６に設けているが、蒸気処理手段１４は家庭電気製品収納部２内の空気を外部に排出するものなので、蒸気処理手段１４の排出蒸気の通路内に一酸化炭素濃度検知手段１２を設けてもよく、これにより、蒸気処理手段１４の動作時に一酸化炭素を検知しやすくすることができる。   In the present embodiment, the carbon monoxide concentration detecting means 12 is provided in the steam receiving portion 16 of the steam processing means 14, but the steam processing means 14 discharges the air in the household electrical appliance storage part 2 to the outside. Therefore, the carbon monoxide concentration detecting means 12 may be provided in the exhaust steam passage of the steam processing means 14, whereby the carbon monoxide can be easily detected during operation of the steam processing means 14.

（実施の形態３）
図７は、本発明の実施の形態３における家庭電気製品収納庫のブロック図を示し、図８は、同家庭電気製品収納庫の断面図を示すものである。 (Embodiment 3)
FIG. 7 shows a block diagram of a household electrical appliance storage in Embodiment 3 of the present invention, and FIG. 8 shows a cross-sectional view of the household electrical appliance storage.

図７および図８に示すように、復帰手段１３は、家庭電気製品収納部２内で異常過熱が発生した場合、それを復帰するもので、家庭電気製品収納部２内に水を散布できるように構成している。制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、復帰手段１３を動作させるようにしている。他の構成は上記実施の形態１または２と同じであり、同一符号を付して説明を省略する。   As shown in FIG. 7 and FIG. 8, the return means 13 recovers when an abnormal overheat occurs in the home appliance storage unit 2, so that water can be sprayed into the home appliance storage unit 2. It is configured. The control means 15 operates the return means 13 when the carbon monoxide concentration of the household electrical appliance storage unit 2 rises and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level. Other configurations are the same as those in the first or second embodiment, and the same reference numerals are given and description thereof is omitted.

上記構成において動作を説明する。家庭電気製品収納部２には主にキッチンで使用される調理家電、例えば、ジャーポット、炊飯器、コーヒーメーカなどの家庭電気製品が収納される。これらの家庭電気製品は第１の給電手段３または第２の給電手段４に接続されたまま置かれることが多い。ジャーポットであれば保温のまま昼夜を問わず、また、使用者の在、不在を問わず、第１の給電手段３または第２の給電手段４に挿入されているのが常であり、炊飯器においても、予約炊飯や保温を考慮しても常時第１の給電手段３または第２の給電手段４に挿入されていることが多い。   The operation in the above configuration will be described. The household electric appliance storage unit 2 stores cooking appliances mainly used in the kitchen, for example, household electric appliances such as jar pots, rice cookers, and coffee makers. These home appliances are often left connected to the first power supply means 3 or the second power supply means 4. If it is a jar pot, it is usually inserted into the first power supply means 3 or the second power supply means 4 regardless of the presence or absence of the user while keeping warm, and whether the user is present or not. Even in consideration of reserved rice cooking and heat retention, the device is often inserted into the first power supply means 3 or the second power supply means 4 at all times.

さらに、これらの家庭電気製品は水利用機器であり、これら家庭電気製品を使用時には蒸気が発生する。そのため、家庭電気製品収納部２の上部に、家庭電気製品から発生した蒸気を庫外に排出する蒸気処理手段１４を設けており、家庭電気製品収納部２内の空気とともに家庭電気製品から発生した蒸気を吸引し、庫外に排出する。   Furthermore, these household electric appliances are water-utilizing devices, and steam is generated when these household electric appliances are used. Therefore, the steam processing means 14 for discharging the steam generated from the home appliance to the outside of the warehouse is provided in the upper part of the home appliance storage unit 2, and the steam generated from the home appliance together with the air in the home appliance storage unit 2. Vapor is sucked and discharged out of the warehouse.

ここで、これら家庭電気製品の使用中に何らかの不具合により家庭電気製品収納部２内で異常過熱が発生した場合、特に発生初期においては不完全燃焼のため一酸化炭素が多く発生する。この場合、発生した熱により家庭電気製品収納部２内の空気は上昇気流が生じる。そこで、家庭電気製品収納部２の上部にある蒸気処理手段１４の蒸気受け部１６に一酸化炭素濃度検知手段１２を設け、一酸化炭素濃度を検出する。   Here, when abnormal overheating occurs in the household electrical appliance storage part 2 due to some trouble during use of these household electrical appliances, a large amount of carbon monoxide is generated due to incomplete combustion, particularly in the initial stage of occurrence. In this case, ascending airflow is generated in the air in the household electrical appliance storage unit 2 due to the generated heat. Therefore, the carbon monoxide concentration detecting means 12 is provided in the steam receiving portion 16 of the steam processing means 14 in the upper part of the household electrical appliance storage portion 2 to detect the carbon monoxide concentration.

一般的に、大気中の一酸化炭素濃度は、１ｐｐｍ以下である。一酸化炭素濃度の上昇率は、上記実施の形態１と同様に、
（ｂ−ａ）／（ｔ２−ｔ１）
で求められる。ここで、ある時点での一酸化炭素濃度が１１ｐｐｍであり、１０秒前の一酸化炭素濃度が１ｐｐｍの場合、上昇率は、（１１−１）／１０＝１となり、一酸化炭素濃度の上昇率が１を超えれば異常と判断するようあらかじめ制御手段１５に規定しておけば、家庭電気製品収納庫内の家庭電気製品への給電を停止する。第１の給電手段３および第２の給電手段４には、特にジャーポットや炊飯器のような熱利用機器が接続されるため、第１の給電手段３および第２の給電手段４への給電が停止すると、接続された家庭電気製品の自己発熱が停止するとともに、復帰手段１３から家庭電気製品収納部２内に水を散布して異常過熱を復帰する。 Generally, the carbon monoxide concentration in the atmosphere is 1 ppm or less. The rate of increase in the carbon monoxide concentration is the same as in the first embodiment.
(Ba) / (t2-t1)
Is required. Here, when the carbon monoxide concentration at a certain point is 11 ppm and the carbon monoxide concentration before 10 seconds is 1 ppm, the rate of increase is (11-1) / 10 = 1, and the carbon monoxide concentration is increased. If the control means 15 preliminarily determines that an abnormality occurs when the rate exceeds 1, power supply to the household electrical appliance in the household electrical appliance storage is stopped. Since the first power supply means 3 and the second power supply means 4 are connected to a heat utilization device such as a jar pot or a rice cooker, power is supplied to the first power supply means 3 and the second power supply means 4. When the operation stops, the self-heating of the connected home electric appliance stops, and water is sprayed from the return means 13 into the home electric appliance storage section 2 to recover from the abnormal overheating.

このとき、表示手段５により、一酸化炭素濃度の上昇を表示するとともに、報知手段６により一酸化炭素濃度の上昇を報知する。   At this time, the display means 5 displays an increase in the carbon monoxide concentration, and the notification means 6 notifies the increase in the carbon monoxide concentration.

以上のように、本実施の形態においては、家庭電気製品収納部２内で異常過熱が発生した場合、それを復帰する復帰手段１３を備え、制御手段１５は、家庭電気製品収納部２の一酸化炭素濃度が上昇し、一酸化炭素濃度検知手段１２の出力上昇率が一定のレベルを超えると、復帰手段１３を動作させるようにしたので、一酸化炭素濃度が一定のレベルを超えると復帰手段１３を動作させ、家庭電気製品収納部２内における異常過熱による被害の拡大を抑制することができる。   As described above, in the present embodiment, when abnormal overheating occurs in the household electrical appliance storage unit 2, the recovery unit 13 is provided to restore it, and the control unit 15 is a part of the household electrical appliance storage unit 2. When the carbon oxide concentration rises and the output increase rate of the carbon monoxide concentration detection means 12 exceeds a certain level, the return means 13 is operated. Therefore, when the carbon monoxide concentration exceeds a certain level, the return means 13 can be operated, and the expansion of damage due to abnormal overheating in the household electrical appliance storage unit 2 can be suppressed.

なお、本実施の形態では、復帰手段１３は、水を散布するように構成しているが、水に代えて、異常過熱を冷却させる冷却剤を散布するようにしてもよく、この場合は、さらに高い効果を得ることができる。   In the present embodiment, the return means 13 is configured to spray water, but instead of water, a coolant that cools abnormal overheating may be sprayed. A higher effect can be obtained.

以上のように本発明にかかる家庭電気製品収納庫は、キャビネット内に収納した家庭電気製品に異常過熱など一酸化炭素を発生する異常が発生した場合に家庭電気製品への給電を停止することで、キャビネット内に収納した家庭電気製品の動作を停止することができ、被害が拡大するのを防止することができるので、家庭電気製品を収納した状態で使用できるようにした家庭電気製品収納庫として有用である。   As described above, the household electrical appliance storage according to the present invention stops power supply to the household electrical appliance when an abnormality that generates carbon monoxide, such as abnormal overheating, occurs in the household electrical appliance stored in the cabinet. Because it can stop the operation of household electrical appliances stored in the cabinet and prevent the damage from spreading, it can be used as a household electrical appliance storage cabinet that can be used with the household electrical appliances stored Useful.
