Description

本発明は、便座表面を短時間で暖房する便座装置に関するものである。   The present invention relates to a toilet seat device for heating a toilet seat surface in a short time.

従来、この種の暖房便座では、図７に示すように内部に空洞部１０１を持つ便座１０２の着座部１０３を透明ポリプロピレン樹脂で構成し、着座部１０３の表面に輻射熱吸収層１０４を設置し、空洞部１０１にはランプヒータ１０５を設置していた。ランプヒータ１０５からの輻射熱は透明ポリプロピレン樹脂製の着座部１０３を透過し、表面の輻射熱吸収層１０４で熱に変換され、着座部１０３を昇温させるというものであった。臀部が接触する輻射熱吸収層１０４で熱の発生が行われるので、便座１０２の内部からコードヒータなどを用いて熱伝導で加熱される方式と比較すると短時間で臀部の暖房が可能となる。また、温度制御はランプヒータ１０５の近傍に置かれたサーモスタット１０６で行い、温度ヒューズ１０７で異常加熱の危険性を防ぐようにしていたものであった（例えば、特許文献１参照）。
特開２０００−１４５９８号公報 Conventionally, in this type of heated toilet seat, as shown in FIG. 7, the seat portion 103 of the toilet seat 102 having a hollow portion 101 is made of a transparent polypropylene resin, and a radiant heat absorption layer 104 is installed on the surface of the seat portion 103. A lamp heater 105 was installed in the cavity 101. The radiant heat from the lamp heater 105 is transmitted through the seating portion 103 made of transparent polypropylene resin, converted into heat by the radiant heat absorption layer 104 on the surface, and the temperature of the seating portion 103 is increased. Since heat is generated in the radiant heat absorption layer 104 in contact with the buttocks, heating of the buttocks can be performed in a short time compared to a method in which heat is conducted from the inside of the toilet seat 102 using a cord heater or the like. Further, the temperature control is performed by a thermostat 106 placed in the vicinity of the lamp heater 105, and the risk of abnormal heating is prevented by the temperature fuse 107 (see, for example, Patent Document 1).
JP 2000-14598 A

しかしながら、前記従来の構成では、ランプヒータは電力変換効率が良いために直ぐ暖まる速暖性能がよく、短時間で温度を上昇することができる反面、ランプヒータの抵抗値はフィラメントが冷めている（トイレ室内の温度相当の温度となっている）時には、定格電力消費時の１／１０以下と小さいため、通電初期には大きな突入電流が流れる。もちろん、フィラメントの抵抗値は短時間に定格抵抗に達して突入電流はすぐに抑制されるのであるが、便座装置に使用するためには、トイレ室内に装備されている他の製品（特にヒータ）と同時に通電された場合に更に大電流が流れることになる。   However, in the above-mentioned conventional configuration, the lamp heater has good power conversion efficiency, so it has a quick warming performance that warms up quickly and can raise the temperature in a short time, but the resistance value of the lamp heater is cooled by the filament ( When the temperature is equivalent to the temperature in the toilet room), a large inrush current flows at the beginning of energization because it is as small as 1/10 or less of the rated power consumption. Of course, the resistance value of the filament reaches the rated resistance in a short time, and the inrush current is immediately suppressed. However, for use in the toilet seat device, other products (especially heaters) installed in the toilet room When energized at the same time, a larger current flows.

一般的にトイレ室内への屋内電力配線は大電流配線ではなく、また、単一電力配線であるため、大電流を想定した漏電遮断器、及び過電流遮断器は配置されていないことが多い。また、トイレ室内の照明器具へも同一電力配線から取られている物も多く、ランプヒータとトイレ室内に装備されている他の製品（例えば、人体局部を洗う洗浄水を加熱する温水ヒータなど）のヒータが同時に通電された場合には、過電流で遮断器が落ちてしまったり、また、屋内電力配線の抵抗成分により電圧降下が発生して、便座装置、トイレ室内に装備されている他の製品、及びトイレ室内照明への供給電圧が低下し、便座装置やトイレ室内に装備されている他の製品の製品性能が低下したり、室内照明の輝度が低下するという課題を有していた。   In general, the indoor power wiring into the toilet room is not a large current wiring and is a single power wiring, and therefore there are often no earth leakage circuit breakers and overcurrent circuit breakers that assume a large current. Also, many lighting fixtures in the toilet room are taken from the same power wiring, and lamp heaters and other products equipped in the toilet room (for example, hot water heaters that heat wash water for washing human body parts) When both heaters are energized at the same time, the circuit breaker will drop due to overcurrent, or a voltage drop will occur due to the resistance component of the indoor power wiring, and the toilet seat device and other equipment installed in the toilet room The supply voltage to the product and the toilet interior lighting is lowered, and there is a problem that the product performance of the toilet seat device and other products installed in the toilet room is degraded and the brightness of the interior lighting is lowered.

上記従来の課題に鑑み、本発明が解決しようとする課題は、省エネルギー性に富み、使い勝手の良い便座装置を提供することにある。   In view of the above-described conventional problems, the problem to be solved by the present invention is to provide a toilet seat device that is rich in energy saving and easy to use.

前記従来の課題を解決するために、本発明の便座装置は、制御手段において人体検知手段にて人体を検知すると、便座を暖める熱源に複数の通電率で一定時間電力を供給した後、複数の通電率よりも高い一定の通電率で便座温度が所定時間内に着座可能温度に達するように制御を行う。   In order to solve the above-described conventional problems, the toilet seat device of the present invention, when the human body is detected by the human body detection means in the control means, after supplying power to the heat source for warming the toilet seat at a plurality of energization rates for a certain period of time, Control is performed so that the toilet seat temperature reaches the seatable temperature within a predetermined time at a constant energization rate higher than the energization rate.

本構成によって、省エネルギー性に富み、使い勝手の良い便座装置を提供することができる。   With this configuration, it is possible to provide a toilet seat device that is rich in energy saving and easy to use.

本発明の便座装置は、速暖性能を有し、かつ使い勝手の良い省エネルギー性に富んだ便座装置を提供することができる。   The toilet seat device according to the present invention can provide a toilet seat device that has quick and warm performance and is easy to use and rich in energy saving.

After supplying power for a certain period of time, by controlling the toilet seat temperature to reach the seatable temperature within a predetermined time at a constant energization rate higher than the plurality of energization rates, a large inrush current is suppressed, and overcurrent The voltage at the circuit breaker drops or the resistance component of the indoor power wiring causes a drop in voltage, which reduces the supply voltage to the toilet seat device, other products installed in the toilet room, and the lighting in the toilet room, It is possible to provide a toilet seat device that is highly energy-saving and easy to use without deteriorating the performance of the toilet seat device or other products installed in the toilet room or reducing the brightness of the room lighting.

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、本実施の形態によって本発明が限定されるものではない。   Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the present embodiment.

（実施の形態１）
図１は本発明の実施の形態１における便座装置のブロック図を示すものであり、図２は本発明の実施の形態１における熱源への通電率を表したグラフである。 (Embodiment 1)
FIG. 1 shows a block diagram of a toilet seat apparatus according to Embodiment 1 of the present invention, and FIG.

図１に示すとおり、便座１０を暖める熱源１１と人体を検知する人体検知手段１２を制御する制御手段１３から構成されている。   As shown in FIG. 1, the heat source 11 warms the toilet seat 10, and the control means 13 which controls the human body detection means 12 which detects a human body.

以上のように構成された便座装置について、以下その動作、作用を説明する。   About the toilet seat apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

熱源１１は便座１０の内部に配設されており、熱源１１の発熱によって便座１０が暖められる。人体検知手段１２はトイレ室内に使用者が在室しているか否かを検出し、制御手段１３に対して在室の有無を信号として出力する。制御手段１３はマイクロコンピュータ及び周辺回路にて構成されており、人体検知手段１２の出力信号をもとに熱源１１への電力供給の制御を行う。   The heat source 11 is disposed inside the toilet seat 10, and the toilet seat 10 is warmed by the heat generated by the heat source 11. The human body detection means 12 detects whether or not a user is present in the toilet room, and outputs the presence / absence of the user to the control means 13 as a signal. The control means 13 is composed of a microcomputer and peripheral circuits, and controls power supply to the heat source 11 based on the output signal of the human body detection means 12.

図２に示すとおり、制御手段３は、人体検知手段２にて人体を検知すると便座１０を暖める熱源１１に供給する電力を、段階的に複数の通電率に上昇させて一定時間電力の供給を行う。その一定時間後、複数の通電率よりも高い一定の通電率にて便座１０の温度が所定時間内に着座可能温度に到達するように制御手段１３において電力供給を行う。熱源１１への通電開始後から所定時間経過後は、設定温度に便座１０温度を維持する保温の通電率にて電力供給を行う。尚、着座可能温度とは、使用者が便座１０に着座した際に不快感を感じない最低温度である。   As shown in FIG. 2, when the human body detecting means 2 detects the human body, the control means 3 increases the power supplied to the heat source 11 that warms the toilet seat 10 to a plurality of energization rates stepwise and supplies the power for a certain period of time. Do. After the predetermined time, the control means 13 supplies power so that the temperature of the toilet seat 10 reaches the seatable temperature within a predetermined time at a constant energization rate higher than a plurality of energization rates. After the elapse of a predetermined time from the start of energization to the heat source 11, power is supplied at an energization rate of heat retention that maintains the toilet seat 10 temperature at the set temperature. The seatable temperature is the lowest temperature at which a user does not feel uncomfortable when seated on the toilet seat 10.

通常は、便座１０の温度をできるだけ早く着座可能温度に到達させるために、通電開始初期から熱源１１へ高い一定の通電率にて通電を行うことが考えられる。しかし、前述の課題にも記載したとおり、熱源１１の抵抗値は熱源１１が冷めている（トイレ室内の温度相当の温度）時には、定格電力消費時の１／１０以下程度と非常に小さいため、通電開始初期において大きな突入電流が流れてしまう。また、トイレ室内で他の製品（特にヒータを搭載した製品）を同時に使用していた場合には更に大きな電流が流れることが想定される。この場合に、一般的にトイレ室内への屋内電力配線は大電流配線ではなく、また、単一電力配線であるため、大電流を想定した漏電遮断器、及び過電流遮断器は配置されていないことが多い。また、トイレ室内の照明器具へも同一電力配線から取られている物も多く、熱源１１とトイレ室内に装備されている他の製品（例えば、人体局部を洗う洗浄水を加熱する温水ヒータなど）のヒータが同時に通電された場合には、過電流で遮断器が落ちてしまったり、また、屋内電力配線の抵抗成分により電圧降下が発生して、便座装置、トイレ室内に装備されている他の製品、及びトイレ室内照明への供給電圧が低下し、便座装置やトイレ室内に装備されている他の製品の性能が低下したり、室内照明の輝度が低下してしまう。   Usually, it is conceivable to energize the heat source 11 at a high constant energization rate from the beginning of energization so that the temperature of the toilet seat 10 reaches the seatable temperature as soon as possible. However, as described in the above-mentioned problem, the resistance value of the heat source 11 is very small, about 1/10 or less of the rated power consumption when the heat source 11 is cold (temperature corresponding to the temperature in the toilet room). A large inrush current flows at the beginning of energization. Further, when other products (particularly products equipped with a heater) are used at the same time in the toilet room, it is assumed that a larger current flows. In this case, generally, the indoor power wiring into the toilet room is not a large current wiring, and since it is a single power wiring, the earth leakage circuit breaker and the overcurrent circuit breaker that assume a large current are not arranged. There are many cases. In addition, many lighting appliances in the toilet room are taken from the same power wiring, and the heat source 11 and other products installed in the toilet room (for example, a hot water heater for heating washing water for washing the human body part) When both heaters are energized at the same time, the circuit breaker will drop due to overcurrent, or a voltage drop will occur due to the resistance component of the indoor power wiring, and the toilet seat device and other equipment installed in the toilet room The supply voltage to the product and the toilet interior lighting decreases, the performance of the toilet seat device and other products installed in the toilet interior decreases, and the brightness of the interior lighting decreases.

一般的に熱源１１の抵抗値は短時間に定格抵抗に達して突入電流はすぐに抑制されるので、通電開始時には複数の通電率で熱源１１に電力を供給し、その後、複数の通電率よりも高い一定の通電率にて制御することで、大きな突入電流を抑え、過電流で遮断機が落ちてしまったり、屋内電力配線の抵抗成分により電圧降下が発生して、便座装置、トイレ室内に装備されている他の製品、及びトイレ室内の照明への供給電圧が低下し、便座装置やトイレ室内に装備されている他の製品の性能が低下したり、室内照明の輝度が低下することなく、省エネルギー性に富み、使い勝手の良い便座装置を提供することができる。   In general, since the resistance value of the heat source 11 reaches the rated resistance in a short time and the inrush current is immediately suppressed, power is supplied to the heat source 11 at a plurality of energization rates at the start of energization, and then from the plurality of energization rates. However, by controlling at a high constant current supply rate, a large inrush current is suppressed, the circuit breaker is dropped due to overcurrent, or a voltage drop occurs due to the resistance component of the indoor power wiring. The supply voltage to the other installed products and the lighting in the toilet room is reduced, the performance of the toilet seat device and other products installed in the toilet room is not reduced, and the brightness of the room lighting is not reduced. Therefore, it is possible to provide a toilet seat device that is excellent in energy saving and easy to use.

また、便座の温度を着座可能な温度に維持するために必要な最低限の電力である保温の通電率に切り替えることで不必要に熱源に通電することがないため、より省エネルギー性に富んだ便座装置となる。   In addition, since the heat source is not unnecessarily energized by switching to the heat retention current rate, which is the minimum power required to maintain the temperature of the toilet seat at a seatable temperature, the toilet seat is more energy efficient. It becomes a device.

なお、本実施の形態においては、段階的に複数の通電率を上昇させながら通電する制御を行ったが、これに限るものではなく、上昇途中で一旦通電率を下げたり、また一定の通電率での通電時間を長くすることも可能であり、このような制御を行うことにより、便座の温度が過剰に上昇することを防ぐことができる。   In the present embodiment, the energization control is performed while increasing the plurality of energization rates in stages. However, the present invention is not limited to this. It is also possible to lengthen the energization time in the case, and by performing such control, it is possible to prevent the temperature of the toilet seat from rising excessively.

（実施の形態２）
図３は本発明の実施の形態２における熱源１１への通電率を表したものである。 (Embodiment 2)
FIG. 3 shows the energization rate to the heat source 11 in Embodiment 2 of the present invention.

本実施の形態が第１の実施の形態と異なる点は、図３に示すとおり、制御手段１３は、人体検知手段１２にて人体を検知すると便座１０を暖める熱源１１に供給する電力の通電率を連続的に上昇させながら一定時間電力の供給を行う。その一定時間後、連続的に上昇させた通電率よりも高い一定の通電率にて便座１０の温度が所定時間内に着座可能温度に到達するように制御手段１３において電力供給を行う。   As shown in FIG. 3, the present embodiment is different from the first embodiment in that the control means 13 supplies the heat supply rate to the heat source 11 that warms the toilet seat 10 when the human body detection means 12 detects the human body. The power is supplied for a certain time while continuously increasing. After the predetermined time, the control means 13 supplies power so that the temperature of the toilet seat 10 reaches the seatable temperature within a predetermined time at a constant energization rate higher than the energization rate continuously increased.

前述したとおり、熱源１１の抵抗値は熱源１１が冷めている（トイレ室内の温度相当の温度）時には、定格電力消費時の１／１０以下程度と非常に小さいため、通電開始初期において大きな突入電流が流れてしまう。しかし、熱源１１へ通電を行うと熱源１１の発熱に従って熱源１１自身の温度も上昇するため、熱源１１の抵抗値も徐々に大きくなり、熱源１１の抵抗値の変化に伴い突入電流も抑制される。   As described above, the resistance value of the heat source 11 is very small, about 1/10 or less of the rated power consumption when the heat source 11 is cold (a temperature corresponding to the temperature in the toilet room). Will flow. However, if the heat source 11 is energized, the temperature of the heat source 11 itself rises as the heat source 11 generates heat, so that the resistance value of the heat source 11 gradually increases, and the inrush current is suppressed as the resistance value of the heat source 11 changes. .

そこで、制御手段１３において、人体検知手段１２にて人体を検知すると便座１０を暖める熱源１１を通電率を連続的に上昇されることで、必要最低限の時間で便座１０の温度が着座可能温度に到達させることができ、使い勝手の良い便座装置を提供することができる。また、不必要に熱源１１に通電することがないため省エネルギー性に富んだ便座装置となる。   Therefore, when the human body detecting means 12 detects the human body in the control means 13, the energization rate of the heat source 11 that warms the toilet seat 10 is continuously increased, so that the temperature of the toilet seat 10 can be seated at the minimum necessary time. Therefore, it is possible to provide an easy-to-use toilet seat device. Further, since the heat source 11 is not unnecessarily energized, the toilet seat device is rich in energy saving.

（実施の形態３）
図４は本発明の実施の形態３における便座装置のブロック図を示すものであり、図５は便座温度の変化を表したグラフである。 (Embodiment 3)
FIG. 4 shows a block diagram of the toilet seat device according to Embodiment 3 of the present invention, and FIG. 5 is a graph showing changes in toilet seat temperature.

図４に示すとおり、室温を検出する室温検出手段１４を有し、制御手段１３は、室温検出手段１５において検出した室温に応じて熱源１１へ通電する所定時間を決定する。   As shown in FIG. 4, it has room temperature detecting means 14 for detecting the room temperature, and the control means 13 determines a predetermined time for energizing the heat source 11 according to the room temperature detected by the room temperature detecting means 15.

図５に示すように、室温が低い時と高い時とでは、人体を検知して熱源１１に通電を開始する直前の便座１０の温度が異なるため、熱源１１に通電を開始してから便座１０が着座可能温度に到達するまでの時間も異なる。例えば、室温が低い時には便座１０温度も低く、便座１０の温度が上昇する速度も遅いため便座１０を着座可能温度に到達させようとすると長い時間熱源１１に通電する必要がある。しかし、室温が高い時にも同じ時間で熱源１１に通電を行うと便座１０の温度は着座可能温度を超えてしまう。逆に、室温が高い時には便座１０の温度も高く、便座１０の温度が上昇する速度も速いため便座１０を着座可能温度に到達させようとすると短い時間熱源１１に通電するだけでよいが、室温が低い時にも同じ時間熱源１１に通電を行うと便座１０の温度は着座可能温度に到達しない。   As shown in FIG. 5, the temperature of the toilet seat 10 immediately before the heat source 11 is detected and the heat source 11 is energized is different between when the room temperature is low and when the room temperature is high. The time required for reaching the seatable temperature is also different. For example, when the room temperature is low, the temperature of the toilet seat 10 is low, and the rate at which the temperature of the toilet seat 10 increases is slow. Therefore, when the toilet seat 10 is to reach the seatable temperature, it is necessary to energize the heat source 11 for a long time. However, when the heat source 11 is energized in the same time even when the room temperature is high, the temperature of the toilet seat 10 exceeds the seatable temperature. On the contrary, when the room temperature is high, the temperature of the toilet seat 10 is also high, and the speed at which the temperature of the toilet seat 10 rises is fast. Therefore, when the toilet seat 10 is made to reach the seatable temperature, it is only necessary to energize the heat source 11 for a short time. When the heat source 11 is energized for the same time even when the temperature is low, the temperature of the toilet seat 10 does not reach the seatable temperature.

そこで、制御手段１３において、室温に応じて熱源１１に通電する所定時間を決定することで、必要最低限の時間で便座１０の温度が着座可能温度に到達させることができ、使い勝手の良い便座装置を提供することができる。また、不必要に熱源１１に通電することがないため省エネルギー性に富んだ便座装置となる。   Therefore, the control means 13 determines the predetermined time during which the heat source 11 is energized according to the room temperature, so that the temperature of the toilet seat 10 can reach the seatable temperature in the minimum necessary time. Can be provided. Further, since the heat source 11 is not unnecessarily energized, the toilet seat device is rich in energy saving.

図６に示すとおり、便座１０の温度を検出する便座温度検出手段１５を有し、制御手段１３は、便座温度検出手段１５において検出した便座の温度に応じて熱源１１に通電する所定時間を決定する。   As shown in FIG. 6, the toilet seat temperature detecting means 15 for detecting the temperature of the toilet seat 10 is provided, and the control means 13 determines a predetermined time for energizing the heat source 11 according to the temperature of the toilet seat detected by the toilet seat temperature detecting means 15. To do.

通常、一旦便座１０を熱源１１で暖めると、ユーザーが使用後に熱源１１への電力の供給を止めた場合、便座１０の温度が下がるまである程度の時間を要する。実使用上において便座装置が使用される間隔は設置環境・使用環境・時間帯等において様々である。例えば、４人家族の朝の時間帯では、通勤や通学のため同一時間帯に連続的に便座装置が使用される。また、頻繁に人の出入りがある公共施設などに便座装置が設置されている場合にも連続的に便座装置が使用される。これらの場合は、便座装置が使用される間隔が非常に短いため便座１０の温度が十分高い状態で熱源１１に通電を開始することになる。この場合においても熱源１１へ通電する所定時間を同一の時間としていた場合には必要以上に通電を行い、無駄に電力を消費してしまうことになる。   Normally, once the toilet seat 10 is warmed by the heat source 11, when the user stops supplying power to the heat source 11 after use, it takes a certain time until the temperature of the toilet seat 10 decreases. The interval at which the toilet seat device is used in actual use varies in the installation environment, use environment, time zone, and the like. For example, in the morning time zone of a family of four, the toilet seat device is continuously used in the same time zone for commuting and attending school. In addition, the toilet seat device is continuously used even when the toilet seat device is installed in a public facility where people frequently go in and out. In these cases, since the interval at which the toilet seat device is used is very short, energization of the heat source 11 is started in a state where the temperature of the toilet seat 10 is sufficiently high. Even in this case, if the predetermined time for energizing the heat source 11 is the same time, the energization is performed more than necessary, and power is wasted.

そこで、制御手段１３において、便座１０の温度に応じて熱源１１に通電する所定時間を決定することで、必要最低限の時間で便座１０の温度が着座可能温度に到達させることができ、使い勝手の良い便座装置を提供することができる。また、不必要に熱源１１に通電することがないため省エネルギー性に富んだ便座装置となる。   Therefore, by determining the predetermined time for energizing the heat source 11 in accordance with the temperature of the toilet seat 10 in the control means 13, the temperature of the toilet seat 10 can reach the seatable temperature in the minimum necessary time. A good toilet seat device can be provided. Further, since the heat source 11 is not unnecessarily energized, the toilet seat device is rich in energy saving.

なお、本実施の形態においては、便座温度検出手段１５は便座内部設置したが、これに限るものではなく、便座の表面部等便座の表面温度と相関性の高い位置であれば同様の効果を得ることができる。   In the present embodiment, the toilet seat temperature detecting means 15 is installed inside the toilet seat, but the present invention is not limited to this, and the same effect can be obtained as long as the position is highly correlated with the surface temperature of the toilet seat such as the surface of the toilet seat. Obtainable.

以上のように、本発明にかかる便座装置は、省エネルギー性に富んだ熱源の制御が可能となるので、他の暖房器具等の用途にも適用できる。   As described above, since the toilet seat device according to the present invention can control a heat source with a high energy saving property, it can be applied to other uses such as a heating appliance.
