本発明の説明において定義される用語は本発明の機能を考慮して定義したものであって、本発明の技術的構成要素を限定する意味として理解してはならない。   The terms defined in the description of the present invention are defined in view of the functions of the present invention, and should not be understood as meanings that limit the technical components of the present invention.

図１に示すように、本発明の実施の形態によるビデの便座温度制御装置は、ビデ１００の本体１１０と、前記本体１１０に備えられ、ヒータ（図示せず）の駆動により瞬間的に暖房となる便座１２０と、前記便座１２０に備えられて人体の着座有無を検知する人体検知センサ２００、そして前記人体検知センサ２００から着座検知信号が印加され、周辺温度に応じて温度領域を差等設定してトイレの周辺温度に応じてヒータ駆動効率を差等制御する制御部（図示せず）と、を含むことを特徴とする。 As shown in FIG. 1, a bidet toilet seat temperature control apparatus according to an embodiment of the present invention includes a main body 110 of a bidet 100 and the main body 110, and instantaneously heats by driving a heater (not shown). The toilet seat 120, the human body detection sensor 200 that is provided in the toilet seat 120 and detects whether or not a human body is seated, and a seating detection signal are applied from the human body detection sensor 200. And a control unit (not shown) that controls the heater driving efficiency in accordance with the ambient temperature of the toilet.

前記制御部には、前記本体１１０に設けられて前記人体検知センサ２００の着座検知信号を受信する受信部３００が備えられることが好ましい。   It is preferable that the control unit includes a receiving unit 300 that is provided in the main body 110 and receives a seating detection signal of the human body detection sensor 200.

前記受信部３００は、本体１１０の前面に設けられているように示したが、その位置に限定されず、その設置位置を多様に変更することができる。   Although the receiving unit 300 is illustrated as being provided on the front surface of the main body 110, the receiving unit 300 is not limited to the position, and the installation position can be variously changed.

前記人体検知センサ２００は、便座１２０に設けられた圧力センサ及び磁気ホールセンサを使用するか、便座１２０または本体１１０に設けられて光を利用して使用者が便座１２０への着座有無によって発生する光の通過可否をチェックし、前記便座１２０への着座有無を検知する光センサなどを使用することができる。 The human body detection sensor 200 uses a pressure sensor and a magnetic Hall sensor provided on the toilet seat 120 or is provided on the toilet seat 120 or the main body 110 to generate light depending on whether the user is seated on the toilet seat 120. Check the passableness of light, such as may be used an optical sensor for detecting the seating presence to the toilet seat 120.

一方、前記目的を達成するための便座の温度制御方法を次に説明するが、上記と同一構成については重複説明を省略する。   On the other hand, a method for controlling the temperature of the toilet seat for achieving the above object will be described below.

まず、第１段階（Ｓ１００）は、圧力センサ及び磁気ホールセンサ、または光センサなどからなる人体検知センサ２００を利用して使用者の検知可否または便座１２０に使用者が着座したか否かを検知する。   First, in the first step (S100), it is detected whether or not the user can be detected or whether or not the user is seated on the toilet seat 120 using the human body detection sensor 200 including a pressure sensor, a magnetic Hall sensor, or an optical sensor. To do.

次に、第２段階（Ｓ２００）は、人体検知または着座検知した場合、目標温度、便座１２０の温度及び時間設定を行い、現在便座１２０の温度と目標温度との差値に基づいてヒータの勾配絶対値を演算し、前記ヒータの駆動時間を決定する。   Next, in the second stage (S200), when human body detection or seating detection is performed, the target temperature, the temperature of the toilet seat 120, and the time are set, and the gradient of the heater is based on the difference value between the current toilet seat 120 temperature and the target temperature. The absolute value is calculated to determine the heater driving time.

また、前記第２段階（Ｓ２００）では、人体検知センサ２００を利用して使用者のトイレ入室有無を検知して判断する段階（Ｓ２１０）、そして前記人体検知センサ２００によりトイレに使用者入室が検知された場合、前記人体検知センサ２００が制御部の受信部３００にＩＲ（Ｉｎｓｔｒｕｃｔｉｏｎ Ｒｅｇｉｓｔｅｒ）命令を発信する段階（Ｓ２２０）と、前記ＩＲ命令が前記制御部の受信部３００に伝送された場合、前記制御部が予め設定された時間の間に前記ＩＲ命令の伝送時間をカウントして係数化する段階（Ｓ２３０）と、をさらに含むことができる。 Further, in the second step (S200), the presence / absence of a user entering the toilet using the human body detection sensor 200 is detected (S210), and the human body detection sensor 200 detects the user entering the toilet. When the human body detection sensor 200 transmits an IR (Instruction Register) command to the receiving unit 300 of the control unit (S220), and when the IR command is transmitted to the receiving unit 300 of the control unit, The controller may further include a step of counting the transmission time of the IR command during a preset time and converting the IR command into a coefficient (S230).

ここで、前記予め設定する時間は、３０秒〜６０秒の範囲内であり、好ましくは６０秒に一定にした方がよいが、前記予め設定する時間は必要に応じて３０〜６０秒の範囲外とするなど多様に変更設定することができる。   Here, the preset time is in the range of 30 to 60 seconds, and preferably 60 seconds, but the preset time is in the range of 30 to 60 seconds as necessary. Various changes can be set, such as outside.

次に、第３段階（Ｓ３００）は、第２段階（Ｓ２００）で決定された駆動時間によって前記ヒータを駆動させて前記便座１２０を瞬間的に加熱してその表面温度が高くなるようにする。   Next, in the third step (S300), the heater is driven according to the driving time determined in the second step (S200) to instantaneously heat the toilet seat 120 so that the surface temperature thereof is increased.

このとき、前記第３段階（Ｓ３００）では、前記演算された駆動時間分にヒータの駆動効率を１００％に制御して前記便座１２０に対する瞬間的な加熱が短い時間内で迅速に行われるようにしたものであり、前記第４段階（Ｓ４００で）は、前記目標温度に到逹するまでにヒータの駆動効率を５０％に制御して前記便座１２０に対する加熱が徐々に行われるようにしたものであり、前記第５段階（Ｓ５００）では前記ヒータ駆動効率を３０％に制御して前記便座１２０の表面温度が目標温度に到達した状態でその目標温度を一定に維持できるようにする。   At this time, in the third step (S300), the heater driving efficiency is controlled to 100% for the calculated driving time so that the instantaneous heating of the toilet seat 120 is performed quickly within a short time. In the fourth stage (in S400), the heating efficiency of the heater is controlled to 50% until the target temperature is reached, so that the toilet seat 120 is gradually heated. In the fifth step (S500), the heater driving efficiency is controlled to 30% so that the target temperature can be maintained constant while the surface temperature of the toilet seat 120 reaches the target temperature.

次に、第４段階（Ｓ４００）は、第３段階（Ｓ３００）で便座１２０の瞬間的な加熱動作が行われた後に、トイレ周辺温度に基づいて目標温度テーブルにより目標温度が再設定され、前記目標温度に到逹するまでヒータを駆動させるようにする。   Next, in the fourth stage (S400), after the instantaneous heating operation of the toilet seat 120 is performed in the third stage (S300), the target temperature is reset by the target temperature table based on the toilet ambient temperature, The heater is driven until the target temperature is reached.

最終的に、第５段階（Ｓ５００）は、第４段階Ｓ４００で便座１２０の温度が前記目標温度に到逹した場合、前記ヒータの駆動効率（例；３０％）を制御して前記目標温度を一定に維持できるようにする。   Finally, in the fifth step (S500), when the temperature of the toilet seat 120 reaches the target temperature in the fourth step S400, the drive temperature (eg, 30%) of the heater is controlled to set the target temperature. To keep it constant.

ここで、前記第５段階（Ｓ５００）は、便座１２０に使用者が着座しないためその着座状態が検知されない場合、前記予め設定された時間の間に着座が検知されない時間をカウントする段階（Ｓ５１０）、そして前記着座が検知されないカウント情報が予め設定された時間を超えたとき、前記制御部がヒータの駆動を中止させた後にヒータの駆動を待機状態に転換させる段階（Ｓ５２０）をさらに含むことができる。   Here, in the fifth step (S500), when the seating state is not detected because the user is not seated on the toilet seat 120, the time during which the seating is not detected during the preset time is counted (S510). In addition, when the count information in which the seating is not detected exceeds a preset time, the control unit further includes a step of switching the heater driving to a standby state after stopping the heater driving (S520). it can.

その他に、前記便座１２０の温度が１５℃以下に下がらないように周辺温度が１５℃以下の使用空間では、前記便座１２０の使用前に前記ヒータの予備加熱を開始させて適正温度及び時間に比例する勾配の制御条件に、前記温度及び時間のうちのいずれか１つの制御条件を満足するか、または前記温度及び時間を含む２つの制御条件をすべて満足したとき、前記ヒータの駆動及びその駆動による効率を制御することができる。   In addition, in a use space where the ambient temperature is 15 ° C. or lower so that the temperature of the toilet seat 120 does not drop below 15 ° C., preheating of the heater is started before use of the toilet seat 120 and is proportional to the appropriate temperature and time. When any one of the temperature and time is satisfied or the two control conditions including the temperature and time are all satisfied, the heater is driven and driven. Efficiency can be controlled.

以上から本発明によるビデの便座温度制御装置及びその方法についての技術思想を添付図面とともに記載したが、これは本発明の最も好適な実施例を例示的に説明したものであって本発明を限定するものではない。   From the above, the technical idea of the bidet toilet seat temperature control apparatus and method according to the present invention has been described with reference to the accompanying drawings.
