【００１４】
【実施例】
以下、本発明の実施例について、図１〜図９を参照しながら説明する。
【００１５】
（実施例１）
図１、図２は、本発明の実施例１におけるブロック図および外観図を示すものである。トイレ室内に配置されたトイレ装置は、トイレ装置周囲の熱的変化により、トイレ室内に人がいるかいないかを検出する人体検知手段５を備え、その検出値に応じて、駆動手段４は便座２及び／又は便蓋３の開閉動作を行う。便座２には暖房のために発熱体として便座ヒータ８が組み込まれている。制御手段６は駆動手段４により、トイレ室内に人がいるときは便座２が閉じ、便蓋３が開いている状態にし、トイレ室内に人がいないときは便座２と便蓋３が閉じた状態にするように便座２及び／又は便蓋３の開閉動作を行う。なお使用者によって故意に便座２及び／又は便蓋３が開閉されたときはこの限りではない。
【００１６】
このとき、トイレ室内に人がいないときは便座２も便蓋３も閉じた状態にしようとするので、例えば、今、便座２と便蓋３がどちらも開いている状態であるとすると、はじめに便座２を閉め、次に便蓋３を閉めようとするが、便座２は便座ヒータ８によって熱を有しているため、トイレ装置周囲に熱的変化が生じるので、人体検知手段５はトイレ室に人がいるものと誤検出をしてしまい、便蓋３が開いた状態にするために、便蓋３の閉動作を行わないという可能性がある。
【００１７】
ここで、無効時間設定手段７は便座ヒータ８の温度に即した適切な時間だけ、制御手段６に駆動手段４の停止信号を出力する。この時間を十分長くすれば熱的変化の影響を回避することができるが、不必要に長いと、トイレ室に人がいるにも関わらず、人がいるときの便座２及び／又は便蓋３の開閉動作を行わないという可能性がある。
【００１８】
そこで、無効時間設定手段７は、便座２の閉動作が完了してから一定時間制御手段６に駆動手段４の停止信号を出力することで、便座２が有した熱によるトイレ装置周囲の熱的変化が緩和されるのを待ち、便蓋３を閉じないという誤動作を行わなくすることができる。
【００１９】
（実施例２）
図３は、本発明の実施例２におけるブロック図を示すものである。便座温度を便座温度設定手段９にて、「高温」と「低温」どちらかに設定できるものとする。この場合、「高温」に設定している場合の方が、「低温」に設定している場合よりトイレ装置周囲に与える熱的変化が大きく、トイレ装置周囲の熱的変化が緩和されるのに要する時間が長いくなる。従って、無効時間設定手段７による、制御手段６に駆動手段４の停止信号を出力する時間を、「低温」に設定している時は「高温」に設定している時よりも短く設定することで、人体検知手段５による人体有りの検出を無効にする時間を必要最低限にすることができ、トイレ室内に人がいるにも関わらず、便蓋３が開かないという誤動作をする可能性を最小限に抑えることができる。
【００２０】
なお、便座温度設定手段９が、「高温」、「低温」の設定に加えて、発熱体８への通電を停止する「切」の設定を有しており、「切」を選択されている場合は、「低温」設定に比べて停止信号を出力する時間を更に短くすることができる。
【００２１】
以上は、便座温度設定手段９による温度設定が、「高温」設定か、「低温」設定か、「切」設定かで説明したが、温度検出手段１０により、発熱体８の実際の温度を検出して、この温度に基づいて、停止信号を出力する時間を設定することでも上記同様の効果を得ることができる。
【００２２】
（実施例３）
図４は、本発明の実施例３におけるブロック図を示すものである。トイレ装置の室温検出手段として室温センサ１１を有す。トイレ室温と便座ヒータ８の温度差が大きいほど、トイレ装置周囲に与える熱的変化が大きいため、無効時間設定手段７が制御手段６に駆動手段４の停止信号を出力する時間を長くしなければならない。このとき、無効時間設定手段７がトイレ室と便座ヒータ８との温度差が大きいときの時間だけ、無効時間設定手段７は制御手段６に駆動手段４の停止信号を出力し、温度差が小さいときは、それより短くする。
【００２３】
すなわち、無効時間設定手段７は、制御手段６に駆動手段４の停止信号を出力する時間を温度差が小さいときは温度差が大きいときよりも短く設定し、別々にその時間を設けることで、人体検知手段５による人体有りの検出を無効にする時間を必要最低限にすることができ、トイレ室内に人がいるにも関わらず、便蓋３が開かないという可能性を最小限に抑えることができる。
【００２４】
（実施例４）
図５、図６は、本発明の実施例４におけるブロック図および外観図を示すものである。トイレ室内に配置されたトイレ装置は、トイレ装置周囲の熱的変化により、トイレ室内に人がいるかいないかを検出する人体検知手段５を備え、その検出値に応じて、駆動手段４は便座２及び／又は便蓋３の開閉動作を行う。また、トイレ室を暖房するために部屋暖房手段１２が配設されている。制御手段６は駆動手段４により、トイレ室内に人がいるときは便座２が閉じ、便蓋３が開いている状態にし、トイレ室内に人がいないときは便座２と便蓋３が閉じた状態にするように便座２及び／又は便蓋３の開閉動作を行う。なお使用者によって故意に便座２及び／又は便蓋３が開閉されたときはこの限りではない。
【００２５】
上記構成において、トイレ室内に人がいないときは便座２も便蓋３も閉じた状態にしようとするので、例えば、今、便座２と便蓋３がどちらも開いている状態であるとすると、はじめに便座２を閉め、次に便蓋３を閉めようとするが、部屋暖房手段１２において暖房運転が開始されると、トイレ装置周囲に熱的変化が生じるので、人体検知手段５はトイレ室に人がいるものと誤検出をしてしまい、便蓋３が開いた状態にするために、便蓋３の閉動作を行わないという可能性がある。
【００２６】
また、便座２と便蓋３がどちらも閉じている状態であるとすると、トイレ室内に人がいなければ、どちらも閉じたままであるが、部屋暖房手段１２において暖房運転が開始されると、トイレ装置周囲に熱的変化が生じるので、人体検知手段５はトイレ室に人がいるものと誤検出をしてしまい、便蓋３を開いた状態にするために、便蓋３の開動作を行ってしまうという可能性がある。
【００２７】
そこで、無効時間設定手段７は、暖房運転が開始してから一定時間制御手段６に駆動手段４の停止信号を出力することで、部屋暖房手段１２によるトイレ装置周囲の熱的変化が緩和されるのを待ち、便蓋３を開けてしまうという誤動作を行わなくすることができる。
【００２８】
（実施例５）
図７は、本発明の実施例５におけるブロック図を示すものである。部屋暖房手段１２への通電率を通電率設定手段１３にて、Ａ％とＢ％（Ａ＞Ｂ）のどちらかに設定できるものとする。この場合、Ａ％に設定している場合の方が、Ｂ％に設定している場合よりトイレ装置周囲に与える熱的変化が大きく、トイレ装置周囲の熱的変化が緩和されるのに要する時間が長いくなる。従って、無効時間設定手段７による、制御手段６に駆動手段４の停止信号を出力する時間を、Ｂ％に設定している時はＡ％に設定している時よりも短く設定することで、人体検知手段５による人体有りの検出を無効にする時間を必要最低限にすることができ、トイレ室内に人がいるにも関わらず、便蓋３が開かないという誤動作をする可能性を最小限に抑えることができる。
【００２９】
（実施例６）
図８は、本発明の実施例６におけるブロック図を示すものである。トイレ装置の室温検出手段として室温センサ１１を有す。トイレ室温と部屋暖房手段１２の温度差が大きいほど、トイレ装置周囲に与える熱的変化が大きいため、無効時間設定手段７が制御手段６に駆動手段４の停止信号を出力する時間を長くしなければならない。このとき、無効時間設定手段７がトイレ室と部屋暖房手段１２との温度差が大きいときの時間だけ無効時間設定手段７は制御手段６に駆動手段４の停止信号を出力し、温度差が小さいときは、それより短くする。
【００３０】
すなわち、無効時間設定手段７は、制御手段６に駆動手段４の停止信号を出力する時間を温度差が小さいときは温度差が大きいときよりも短く設定でき、別々にその時間を設けることで、人体検知手段５による人体有りの検出を無効にする時間を必要最低限にすることができ、トイレ室内に人がいるにも関わらず、便蓋３が開かないという可能性を最小限に抑えることができる。
【００３１】
（実施例７）
図９は、本発明の実施例７におけるブロック図を示すものである。製造工程で人体検知手段５による便座２及び／又は便蓋３の開閉検査をするときは、生産性を上げるために、できるだけ短時間で終えなければならない。人体無しを検出して便座２が閉じたあと、すぐに人体有りの検出を行わせようとしても、無効時間設定手段７が制御手段６に駆動手段４の停止信号を出力する時間が存在するために、人体検知のタイミングを遅らせる必要があり、工程時間を不必要に長くしてしまう。
【００３２】
そこで、設定選択手段としてトイレ装置に配設されたスイッチ１４を用いることによって、無効時間設定手段７が制御手段６に駆動手段４の停止信号を出力する時間をゼロとすることで、人体の有無に応じてすぐに便座２及び／又は便蓋３の開閉動作を迅速に検査することができ、製造工程の工程時間を短くすることができる。
【００３３】
【発明の効果】
以上のように、請求項１〜７に記載の発明によれば、以下のような効果が得られる。
【００３４】
人体検知手段が便座及び／又は便蓋に組み込まれた発熱体の温度又は部屋暖房手段による暖房の影響で人体の有無を誤検出し、便座及び／又は便蓋を誤って開閉動作することがなく、使用者のトイレ装置の使用状態に即した便座及び／又は便蓋の開閉動作を提供することができる。

[0014]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0015]
Example 1
1 and 2 are a block diagram and an external view of the first embodiment of the present invention. The toilet apparatus disposed in the toilet room includes human body detecting means 5 for detecting whether or not a person is present in the toilet room due to a thermal change around the toilet apparatus, and the driving means 4 is provided with the toilet seat 2 according to the detected value. And / or the toilet lid 3 is opened and closed. A toilet seat heater 8 is incorporated in the toilet seat 2 as a heating element for heating. The control means 6 is driven by the drive means 4 so that the toilet seat 2 is closed and the toilet lid 3 is opened when there is a person in the toilet room, and the toilet seat 2 and the toilet lid 3 are closed when there is no person in the toilet room. The toilet seat 2 and / or the toilet lid 3 are opened and closed as described above. This is not the case when the toilet seat 2 and / or the toilet lid 3 are intentionally opened and closed by the user.
[0016]
At this time, when there is no person in the toilet room, the toilet seat 2 and the toilet lid 3 are closed. For example, if both the toilet seat 2 and the toilet lid 3 are now open, The toilet seat 2 is closed and then the toilet lid 3 is closed. Since the toilet seat 2 is heated by the toilet seat heater 8, a thermal change occurs around the toilet device. There is a possibility that the closing operation of the toilet lid 3 is not performed in order to make the toilet lid 3 open by erroneously detecting that there is a person in the room.
[0017]
Here, the invalid time setting means 7 outputs a stop signal of the driving means 4 to the control means 6 for an appropriate time according to the temperature of the toilet seat heater 8. If this time is sufficiently long, the influence of the thermal change can be avoided, but if it is unnecessarily long, the toilet seat 2 and / or the toilet lid 3 when there is a person even though there is a person in the toilet room. There is a possibility that the opening / closing operation is not performed.
[0018]
Therefore, the invalid time setting means 7 outputs a stop signal of the driving means 4 to the control means 6 for a certain time after the closing operation of the toilet seat 2 is completed, so that the heat around the toilet device due to the heat of the toilet seat 2 is generated. It is possible to wait for the change to be alleviated and to avoid a malfunction of not closing the toilet lid 3.
[0019]
(Example 2)
FIG. 3 shows a block diagram in the second embodiment of the present invention. The toilet seat temperature can be set to either “high temperature” or “low temperature” by the toilet seat temperature setting means 9. In this case, when “high temperature” is set, the thermal change around the toilet device is larger than when “low temperature” is set, and the thermal change around the toilet device is alleviated. It takes longer time. Accordingly, the time for outputting the stop signal of the driving means 4 to the control means 6 by the invalid time setting means 7 should be set shorter when set to “low temperature” than when set to “high temperature”. Therefore, it is possible to minimize the time required to invalidate the detection of the presence of the human body by the human body detection means 5, and there is a possibility that the toilet lid 3 does not open despite the presence of a person in the toilet room. Can be minimized.
[0020]
The toilet seat temperature setting means 9 has a setting of “off” for stopping energization of the heating element 8 in addition to the settings of “high temperature” and “low temperature”, and “off” is selected. In this case, the time for outputting the stop signal can be further shortened compared to the “low temperature” setting.
[0021]
The above has been described based on whether the temperature setting by the toilet seat temperature setting means 9 is “high temperature” setting, “low temperature” setting, or “off” setting, but the temperature detection means 10 detects the actual temperature of the heating element 8. The same effect as described above can be obtained by setting the time for outputting the stop signal based on this temperature.
[0022]
(Example 3)
FIG. 4 shows a block diagram in the third embodiment of the present invention. A room temperature sensor 11 is provided as a room temperature detection means of the toilet apparatus. As the temperature difference between the toilet room temperature and the toilet seat heater 8 is larger, the thermal change applied to the surroundings of the toilet apparatus is larger. Therefore, the time for the invalid time setting means 7 to output the stop signal of the driving means 4 to the control means 6 must be lengthened. Don't be. At this time, the invalid time setting means 7 outputs a stop signal of the driving means 4 to the control means 6 only during the time when the invalid time setting means 7 has a large temperature difference between the toilet room and the toilet seat heater 8, and the temperature difference is small. When it is shorter than that.
[0023]
In other words, the invalid time setting means 7 sets the time for outputting the stop signal of the driving means 4 to the control means 6 when the temperature difference is small and shorter than when the temperature difference is large, and separately provides the time, The time for invalidating the presence of the human body by the human body detection means 5 can be minimized, and the possibility that the toilet lid 3 will not open despite the presence of a person in the toilet room is minimized. Can do.
[0024]
(Example 4)
5 and 6 show a block diagram and an external view according to the fourth embodiment of the present invention. The toilet apparatus disposed in the toilet room includes human body detecting means 5 for detecting whether or not a person is present in the toilet room due to a thermal change around the toilet apparatus, and the driving means 4 is provided with the toilet seat 2 according to the detected value. And / or the toilet lid 3 is opened and closed. In addition, room heating means 12 is provided to heat the toilet room. The control means 6 is driven by the drive means 4 so that the toilet seat 2 is closed and the toilet lid 3 is opened when there is a person in the toilet room, and the toilet seat 2 and the toilet lid 3 are closed when there is no person in the toilet room. The toilet seat 2 and / or the toilet lid 3 are opened and closed as described above. This is not the case when the toilet seat 2 and / or the toilet lid 3 are intentionally opened and closed by the user.
[0025]
In the above configuration, when there is no person in the toilet room, the toilet seat 2 and the toilet lid 3 are both closed. For example, if both the toilet seat 2 and the toilet lid 3 are now open, At first, the toilet seat 2 is closed, and then the toilet lid 3 is closed. However, when the heating operation is started in the room heating means 12, a thermal change occurs around the toilet device, so that the human body detection means 5 is placed in the toilet room. There is a possibility that the closing operation of the toilet lid 3 is not performed in order to erroneously detect that there is a person and to make the toilet lid 3 open.
[0026]
Further, if both the toilet seat 2 and the toilet lid 3 are in a closed state, if there is no person in the toilet room, the toilet seat 2 and the toilet lid 3 are both closed. Since a thermal change occurs around the device, the human body detection means 5 erroneously detects that there is a person in the toilet room, and performs the opening operation of the toilet lid 3 to make the toilet lid 3 open. There is a possibility that.
[0027]
Therefore, the invalid time setting means 7 outputs a stop signal of the driving means 4 to the control means 6 for a certain period of time after the heating operation is started, so that the thermal change around the toilet device by the room heating means 12 is alleviated. It is possible to eliminate a malfunction of opening the toilet lid 3 after waiting.

(Example 5)
FIG. 7 shows a block diagram in the fifth embodiment of the present invention. It is assumed that the energization rate for the room heating means 12 can be set to either A% or B% (A> B) by the energization rate setting means 13. In this case, when A% is set, the thermal change given to the toilet device is larger than when B% is set, and the time required for the thermal change around the toilet device to be alleviated Becomes longer. Therefore, by setting the time for outputting the stop signal of the driving means 4 to the control means 6 by the invalid time setting means 7 when set to B%, it is set shorter than when set to A%. The time for invalidating the presence of the human body by the human body detection means 5 can be minimized, and the possibility that the toilet lid 3 does not open even though there is a person in the toilet room is minimized. Can be suppressed.
[0029]
(Example 6)
FIG. 8 shows a block diagram in the sixth embodiment of the present invention. A room temperature sensor 11 is provided as a room temperature detection means of the toilet apparatus. As the temperature difference between the toilet room temperature and the room heating means 12 is larger, the thermal change applied to the surroundings of the toilet device is larger, so that the invalid time setting means 7 must extend the time for outputting the stop signal of the driving means 4 to the control means 6. I must. At this time, the invalid time setting means 7 outputs a stop signal of the driving means 4 to the control means 6 for a time when the invalid time setting means 7 has a large temperature difference between the toilet room and the room heating means 12, and the temperature difference is small. When it is shorter than that.
[0030]
That is, the invalid time setting means 7 can set the time for outputting the stop signal of the driving means 4 to the control means 6 when the temperature difference is small, shorter than when the temperature difference is large, and by providing the time separately, The time for invalidating the presence of the human body by the human body detection means 5 can be minimized, and the possibility that the toilet lid 3 will not open despite the presence of a person in the toilet room is minimized. Can do.
[0031]
(Example 7)
FIG. 9 shows a block diagram in the seventh embodiment of the present invention. When performing the opening / closing inspection of the toilet seat 2 and / or the toilet lid 3 by the human body detection means 5 in the manufacturing process, it must be completed in as short a time as possible in order to increase productivity. Even if the presence of a human body is detected immediately after the absence of a human body is detected and the toilet seat 2 is closed, there is a time for the invalid time setting means 7 to output a stop signal for the driving means 4 to the control means 6. In addition, it is necessary to delay the human body detection timing, which unnecessarily lengthens the process time.
[0032]
Therefore, by using the switch 14 provided in the toilet device as the setting selection means, the time when the invalid time setting means 7 outputs the stop signal of the driving means 4 to the control means 6 is set to zero, so that the presence or absence of a human body Accordingly, the opening / closing operation of the toilet seat 2 and / or the toilet lid 3 can be quickly inspected, and the manufacturing process time can be shortened.
[0033]
【The invention's effect】
As described above, according to the first to seventh aspects of the invention, the following effects can be obtained.
[0034]
The human body detection means does not erroneously detect the presence or absence of a human body due to the temperature of the heating element incorporated in the toilet seat and / or the toilet lid or the effect of heating by the room heating means, and the toilet seat and / or the toilet lid are not erroneously opened and closed. The toilet seat and / or the toilet lid can be opened and closed in accordance with the usage state of the user's toilet device.
