Description

本発明は、例えば、給水口の近傍に位置した人体(手や足等)を検知して、給水が行われるトイレや洗面台の自動給水装置および自動給水装置の故障診断方法に関する。   The present invention relates to, for example, an automatic water supply device for a toilet or a wash basin where water is supplied by detecting a human body (such as a hand or a foot) located in the vicinity of a water supply port, and a failure diagnosis method for the automatic water supply device.

従来、トイレや洗面台などの自動給水装置として、例えば、図6に示すように、一端部が給水源側に連通するとともに、他端部が給水口側に連通する通水路(図示せず)の途中に配置された電磁弁50と、給水口(図示せず)の近傍に配置された人体検知センサとしての赤外線センサ60と、洗面台が取り付けられた壁面の下部(給水口の下方)に配置された制御箱(図示せず)とを備えたものが知られている(特許文献1参照)。   Conventionally, as an automatic water supply device such as a toilet or a washstand, for example, as shown in FIG. 6, a water passage (not shown) having one end communicating with a water supply source and the other end communicating with a water supply side. In the lower part of the wall surface (below the water supply port) to which the electromagnetic valve 50, the infrared sensor 60 as a human body detection sensor arranged in the vicinity of the water supply port (not shown), and the washstand is attached. What is provided with the control box (not shown) arrange | positioned is known (refer patent document 1).

電磁弁50は、通水路に配置された主弁部(図示せず)を開閉して、通水路の流量を調整できる構成になっている。そして、電磁弁50は、電源回路67の電源線eと、制御回路66の出力信号線fとが接続され、該出力信号線fと入力信号線dとが制御回路66において電気的に接続されることによって、駆動するように構成されている。   The electromagnetic valve 50 is configured to be able to adjust the flow rate of the water passage by opening and closing a main valve portion (not shown) disposed in the water passage. The solenoid valve 50 is connected to the power supply line e of the power supply circuit 67 and the output signal line f of the control circuit 66, and the output signal line f and the input signal line d are electrically connected in the control circuit 66. It is comprised so that it may drive.

赤外線センサ60は、赤外光を給水口の下方に向けて発光する発光回路61と、該発光回路61からの赤外光を受光するとともに、受光した赤外光の光量を電圧に変換する受光回路62とを有している。また、赤外線センサ60は、後述する制御箱の中継端子65に接続されるコネクタ64と、発光回路61および受光回路62に一端部が接続されるとともに、前記コネクタ64に他端部が接続されるリード線(a〜d)63を有するリード線付き接続用コネクタを備えている。   The infrared sensor 60 emits infrared light toward the lower side of the water supply port, and receives the infrared light from the light emitting circuit 61 and receives the infrared light from the light emitting circuit 61 and converts the received light quantity into a voltage. Circuit 62. The infrared sensor 60 has one end connected to a connector 64 connected to a relay terminal 65 of the control box, which will be described later, and the light emitting circuit 61 and the light receiving circuit 62, and the other end connected to the connector 64. A connector for connecting with lead wires having lead wires (a to d) 63 is provided.

制御箱は、上述した赤外線センサ60のリード線付き接続用コネクタのコネクタ64が接続される中継端子65と、赤外線センサ60の検知信号に基づいて電磁弁50を駆動させて給水口に給水する制御回路66と、電磁弁50、赤外線センサ60、制御回路66に電源を供給する電源回路67とを備えている。   The control box controls the relay terminal 65 to which the connector 64 of the connector with a lead wire of the infrared sensor 60 described above is connected and the electromagnetic valve 50 based on the detection signal of the infrared sensor 60 to supply water to the water supply port. A circuit 66, a solenoid valve 50, an infrared sensor 60, and a power supply circuit 67 that supplies power to the control circuit 66 are provided.

そして、給水口の下方に差し出された人の手の有無により、赤外線センサ60の受光回路62における赤外線の受光量(電圧)が変化することによって、閉状態の電磁弁50が開いて、給水口において所定時間の給水が行われる。   Then, the amount of received light (voltage) of the infrared light in the light receiving circuit 62 of the infrared sensor 60 changes depending on the presence or absence of the hand of a person that is pushed out below the water supply port, so that the electromagnetic valve 50 in the closed state is opened to supply water. Water is supplied for a predetermined time at the mouth.

しかしながら、前記従来の自動給水装置において、給水口の下方に、手を差し出しても、すなわち赤外線センサ60の人体検知領域に手(人体)を配置しても、給水口から水が出ないという故障が生じた場合、その故障原因が、電源回路67、制御回路(基板)66、電磁弁50、赤外線センサ60のいずれであるのか、不明である。このため、電源回路67、制御回路66、電磁弁50、赤外線センサ60を順次診断していき、故障箇所を特定しているのが現況となっている。したがって、故障箇所を特定するのに時間を要するという問題がある。   However, in the conventional automatic water supply apparatus, even if a hand is put out below the water supply port, that is, even if a hand (human body) is placed in the human body detection area of the infrared sensor 60, water does not come out from the water supply port. If this occurs, it is unclear whether the cause of the failure is the power supply circuit 67, the control circuit (substrate) 66, the electromagnetic valve 50, or the infrared sensor 60. For this reason, the power supply circuit 67, the control circuit 66, the electromagnetic valve 50, and the infrared sensor 60 are diagnosed sequentially, and the fault location is specified. Therefore, there is a problem that it takes time to identify the failure location.

ところで、電源回路67の電源線cおよび制御回路66の入力信号線dを電気的に接続して、電磁弁50を駆動させて給水ができれば、赤外線センサ60のみに故障があり、電源回路67、電磁弁50、制御回路66は正常であると診断できる。したがって、故障診断する際に、電磁弁50の電源線および信号線を電気的に接続できれば、診断作業の効率化が図れるが、このような技術思想は、前記公報には、何ら開示されていない。   By the way, if the power supply line 67 of the power supply circuit 67 and the input signal line d of the control circuit 66 are electrically connected to drive the electromagnetic valve 50 to supply water, only the infrared sensor 60 has a failure, and the power supply circuit 67, The solenoid valve 50 and the control circuit 66 can be diagnosed as normal. Therefore, if the power supply line and the signal line of the solenoid valve 50 can be electrically connected when performing failure diagnosis, the efficiency of the diagnosis work can be improved. However, such a technical idea is not disclosed in the publication. .

そこで、本発明は、故障診断する際に、人体検知センサにおける故障の有無を最初に判断できるようにした自動給水装置および自動給水装置の故障診断方法を提供することを課題とする。   Accordingly, an object of the present invention is to provide an automatic water supply apparatus and a failure diagnosis method for an automatic water supply apparatus that can first determine the presence or absence of a failure in a human body detection sensor when performing a failure diagnosis.

In the automatic water supply apparatus in which the detection signal is input from the light receiving circuit 22 of the human body detection sensor 2 to the control circuit 5 through the input signal line d, the relay terminal 4 from which the connector 3 with lead wire is removed is output. And a jumper-line-inspection connector 7 that electrically connects the power line c of the power circuit 6 and the input signal line d of the control circuit 5.

That is, the power supply line c connected to the human body detection sensor 2 and the input signal line d are electrically connected by the inspection connector 7 with a jumper line, and the output signal line of the control circuit 5 that drives the electromagnetic valve 1 is electrically connected. Connected. At this time, if water is supplied, it is possible to diagnose that only the human body detection sensor 2 is out of order without diagnosing the power supply circuit 6, the control circuit 5, and the electromagnetic valve 1.

また、本発明に係る自動給水装置によれば、通水路9に配置される電磁弁1と、発光回路21および受光回路22によって人体を検知する人体検知センサ2と、人体検知センサ2の受光回路22の検知信号に基づいて電磁弁1を駆動させて、通水路9の通水を制御する制御回路5と、電磁弁1、人体検知センサ2、制御回路5に電源を供給する電源回路6とが配置されるとともに、人体検知センサ2と制御回路5との間に、相互の信号を送受信するための中継端子4、および、該中継端子4に接続されるリード線付き接続用コネクタ3が配置され、中継端子4およびリード線付き接続用コネクタ3によって、人体検知センサ2の発光回路21に、電源回路6の電源線aおよび制御回路5の出力信号線bが電気的に接続されるとともに、人体検知センサ2の受光回路22に、電源回路6の電源線cおよび制御回路5の入力信号線dが電気的に接続され、制御回路5から人体検知センサ2の発光回路21に、出力信号線bを通して発光制御信号が出力されるとともに、人体検知センサ2の受光回路22から制御回路5に、入力信号線dを通して前記検知信号が入力される自動給水装置において、前記制御回路5に、リード線付き接続用コネクタ3が前記中継端子4から取り外されたことを検知するコネクタ検知手段41と、該コネクタ検知手段41の検知信号に基づいて、電源回路6の電源線cと制御回路5の入力信号線dとを電気的に接続して、電磁弁1を強制的に駆動させる強制駆動手段42とを備えたことを特徴とする。   Moreover, according to the automatic water supply apparatus which concerns on this invention, the electromagnetic valve 1 arrange | positioned in the water flow path 9, the human body detection sensor 2 which detects a human body with the light emission circuit 21 and the light reception circuit 22, and the light reception circuit of the human body detection sensor 2 A control circuit 5 for controlling the water flow through the water passage 9 by driving the electromagnetic valve 1 based on the detection signal 22; a power supply circuit 6 for supplying power to the electromagnetic valve 1, the human body detection sensor 2, and the control circuit 5; Between the human body detection sensor 2 and the control circuit 5, a relay terminal 4 for transmitting and receiving mutual signals and a connector 3 with a lead wire connected to the relay terminal 4 are disposed. The relay terminal 4 and the connecting connector 3 with lead wires electrically connect the power line a of the power circuit 6 and the output signal line b of the control circuit 5 to the light emitting circuit 21 of the human body sensor 2.

That is, it is detected that the connector 3 with lead wire is detached from the relay terminal 4, and a drive signal is transmitted from the control circuit 5 to the solenoid valve 1 based on this detection signal.

In the solenoid valve 1, the power supply line e of the power supply circuit 6 and the output signal line f of the control circuit 5 are connected, and the output signal line f and the input signal line d are electrically connected in the control circuit 5.

人体検知センサ2は、赤外線を発光する発光回路21と、該発光回路21からの赤外光を受光する受光回路22とを有する赤外線センサが使用されている。そして、人体検知センサ2は、赤外光が人体(胴部、手、足のうちいずれか)に向けて発光するように、給水口8の近傍に配置されている。すなわち、給水口8の近傍に人体検知領域が形成され、この人体検知領域に人体が位置することによって、赤外光が遮られて、赤外光の光量(電圧)が変化する。この変化した信号が、検知信号として制御回路5に入力信号線dを通って入力される。   As the human body detection sensor 2, an infrared sensor having a light emitting circuit 21 that emits infrared light and a light receiving circuit 22 that receives infrared light from the light emitting circuit 21 is used. And the human body detection sensor 2 is arrange | positioned in the vicinity of the water supply opening | mouth 8 so that infrared light may light-emitted toward a human body (any one of a trunk | drum, a hand, and a leg | foot). That is, a human body detection region is formed in the vicinity of the water supply port 8, and the human body is positioned in this human body detection region, whereby infrared light is blocked and the amount (voltage) of infrared light changes. This changed signal is input to the control circuit 5 through the input signal line d as a detection signal.

ここで、上述した自動給水装置を備えた洗面台の構成について簡単に図2を参照して説明する。該洗面台Bは、壁面に取り付けられた洗面器(図示せず)と、該洗面器の上方に配置された給水口8と、該給水口8に一端部側が連通するとともに、給水源に他端部側が連通する通水路9と、該通水路9の途中に配置された前記自動給水装置Aの電磁弁1と、給水口8の近傍に配置された前記自動給水装置Aの人体検知センサ2と、電磁弁1および人体検知センサ2を制御する制御部が内設された制御箱10とを備えている。   Here, the structure of the wash basin provided with the automatic water supply apparatus mentioned above is demonstrated easily with reference to FIG. The wash basin B has a wash basin (not shown) attached to the wall surface, a water supply port 8 disposed above the wash basin, one end side communicating with the water supply port 8, and other water supply sources. A water passage 9 with which the end side communicates, an electromagnetic valve 1 of the automatic water feeder A disposed in the middle of the water passage 9, and a human body detection sensor 2 of the automatic water feeder A disposed in the vicinity of the water inlet 8 And a control box 10 in which a controller for controlling the electromagnetic valve 1 and the human body detection sensor 2 is provided.

つぎに使用態様について説明する。給水口8の下方に手を差し入れても給水が行われない場合、すなわち、故障が生じた場合、制御箱10を開いて、最初に、中継端子4からリード線付き接続用コネクタ3を取り外し、ジャンパ線付き検査用コネクタ7を中継端子4に接続して、給水の有無を確認する。この際、給水が行われれば、人体検知センサ2のみが故障であると診断できる。給水が行われない場合、電源回路6、制御回路5(基板)、電磁弁1のいずれが故障しているのかを順次診断する。   Next, the usage mode will be described. If water is not supplied even if a hand is inserted below the water supply port 8, that is, if a failure occurs, the control box 10 is opened, and the connector 3 with lead wire is first removed from the relay terminal 4, The jumper-wired inspection connector 7 is connected to the relay terminal 4 to confirm the presence or absence of water supply. At this time, if water supply is performed, it can be diagnosed that only the human body detection sensor 2 is faulty. When water supply is not performed, the power supply circuit 6, the control circuit 5 (substrate), and the solenoid valve 1 are sequentially diagnosed.

以上説明したように、本実施形態に係る自動給水装置は、故障が生じた場合、最初に、リード線付き接続用コネクタ3を中継端子4から取り外し、該中継端子4にジャンパ線付き検査用コネクタ7を接続して、電磁弁1を駆動させて、給水の有無を確認することで、人体検知センサ2のみに故障があると診断できるので、故障診断作業を短時間で処理できるようになる。   As described above, in the automatic water supply apparatus according to the present embodiment, when a failure occurs, first, the connector 3 with lead wire is removed from the relay terminal 4 and the test connector with jumper wire is connected to the relay terminal 4. 7 is connected and the solenoid valve 1 is driven to check the presence or absence of water supply, so that only the human body detection sensor 2 can be diagnosed as having a failure, so that the failure diagnosis work can be processed in a short time.

なお、本発明に係る自動給水装置は、前記実施の形態に限定することなく種々変更することができる。   In addition, the automatic water supply apparatus which concerns on this invention can be variously changed without limiting to the said embodiment.

例えば、前記実施形態の場合、電磁弁1に接続される、電源回路6の電源線cと制御回路5の入力信号線dとを電気的に接続するものとして、ジャンパ線付き検査用コネクタ7を使用したが、図3に示すように、リード線付き接続用コネクタ3が中継端子4から取り外されたことを検知するコネクタ検知手段41を中継端子4に配置するとともに、該コネクタ検知手段41の検知信号に基づいて、電磁弁1を強制的に駆動させる強制駆動手段42を配置するようにしてもよい。   For example, in the case of the above embodiment, the jumper-wire-inspected connector 7 is assumed to be electrically connected to the power supply line c of the power supply circuit 6 and the input signal line d of the control circuit 5 connected to the electromagnetic valve 1. Although used, as shown in FIG. 3, the connector detection means 41 for detecting that the connector 3 with a lead wire has been removed from the relay terminal 4 is disposed on the relay terminal 4, and the detection of the connector detection means 41 is performed. Forcible driving means 42 for forcibly driving the electromagnetic valve 1 may be arranged based on the signal.

係る自動給水装置によれば、故障箇所を診断する場合、図4(a)に示すように、最初に、人体検知センサ2のリード線付き接続用コネクタ3を中継端子4から取り外す。すなわち、リード線付き接続用コネクタ3が中継端子4から取り外されたか否かをコネクタ検知手段41によって検知し(S1)、この検知信号に基づいて、制御回路5から強制駆動手段42に駆動信号を出力して、電磁弁1を強制駆動する(S2)。   According to such an automatic water supply apparatus, when diagnosing a failure location, first, the connector 3 with a lead wire of the human body detection sensor 2 is removed from the relay terminal 4 as shown in FIG. That is, it is detected by the connector detection means 41 whether or not the connector 3 with lead wire is removed from the relay terminal 4 (S1), and a drive signal is sent from the control circuit 5 to the forced drive means 42 based on this detection signal. Then, the electromagnetic valve 1 is forcibly driven (S2).

コネクタ検知手段41として、有接点のスイッチング素子(例えばリミットスイッチ)、または、無接点のスイッチング素子(例えばトランジスタ)が使用され、リード線付き接続用コネクタ3が中継端子4から取り外されると、図4(b)に示すように、スイッチング素子からHI信号が出力され、このHI信号の立ち上がりを起点にして、電磁弁1を所定時間(5秒程度)駆動させる駆動信号(所定幅を有するパルス信号)が制御回路5から強制駆動手段42に出力され、電磁弁1が強制駆動する。この強制駆動によって給水が行われれば、電源回路6、制御回路5、電磁弁1には、異常はなく、人体検知センサ2のみに故障があると判断できる。   As the connector detecting means 41, a contact switching element (for example, a limit switch) or a contactless switching element (for example, a transistor) is used, and when the connector 3 with lead wire is removed from the relay terminal 4, FIG. As shown in (b), a HI signal is output from the switching element, and a drive signal (pulse signal having a predetermined width) for driving the electromagnetic valve 1 for a predetermined time (about 5 seconds) starting from the rising edge of the HI signal. Is output from the control circuit 5 to the forcible drive means 42, and the solenoid valve 1 is forcibly driven. If water supply is performed by this forced drive, it can be determined that there is no abnormality in the power supply circuit 6, the control circuit 5, and the electromagnetic valve 1, and only the human body detection sensor 2 has a failure.

また、図5に示すように、電源回路6の電源線cと制御回路5の入力信号線dとの間に、電磁弁1を手動でオン・オフする手動スイッチSWを接続するようにしてもよい。そして、故障箇所を診断する場合、最初に、手動スイッチSWを外部から手動でオン操作する。すなわち、電磁弁1の電源線cと信号線dとが手動スイッチSWによって電気的に接続される。   Further, as shown in FIG. 5, a manual switch SW for manually turning on / off the electromagnetic valve 1 may be connected between the power supply line c of the power supply circuit 6 and the input signal line d of the control circuit 5. Good. And when diagnosing a fault location, first, the manual switch SW is manually turned on from the outside. That is, the power supply line c and the signal line d of the electromagnetic valve 1 are electrically connected by the manual switch SW.

そして、この手動スイッチSWをオンした際に、給水が行われれば、電磁弁1、制御回路5、電源回路6を診断することなく、人体検知センサ2のみが故障であると診断できる。但し、この手動スイッチSWは、作業者のみがオン・オフ操作できるように、例えば、制御箱10の内壁に取り付けることが好ましい。   If water is supplied when the manual switch SW is turned on, it is possible to diagnose that only the human body detection sensor 2 is out of order without diagnosing the solenoid valve 1, the control circuit 5, and the power supply circuit 6. However, this manual switch SW is preferably attached to, for example, the inner wall of the control box 10 so that only the operator can turn it on / off.

また、前記実施形態の場合、人体検知センサ2として赤外線センサを備えた自動給水装置Aを例にとって説明したが、超音波センサ、または、可視光センサを備えた自動給水装置であってもよく、発光された光を、遮断したり、反射したりすることで、人体を検知する光学式センサを備えた自動給水装置であってもよい。   Moreover, in the case of the said embodiment, although demonstrated as an example the automatic water supply apparatus A provided with the infrared sensor as the human body detection sensor 2, an automatic water supply apparatus provided with the ultrasonic sensor or the visible light sensor may be sufficient, The automatic water supply apparatus provided with the optical sensor which detects a human body by interrupting | blocking or reflecting the emitted light may be sufficient.

また、前記実施形態の場合、自動給水装置として、洗面台を例にとって説明したが、トイレの自動水洗装置であっても、同様の効果を奏することは言うまでもない。   Moreover, in the case of the said embodiment, although the washstand was demonstrated as an example as an automatic water supply apparatus, even if it is an automatic water washing apparatus of a toilet, it cannot be overemphasized that there exists the same effect.
