Description

【0001】
【発明の属する技術分野】
本発明は人体検知装置を用いた便器電装品に係り、特に便蓋の自動開閉装置等に適用するのに好適な便器電装品に関する。
【0002】
【従来の技術】
第3図は便蓋の自動開閉装置を備えた洋風便器の斜視図である。この洋風便器10に便座ボックス12が設置され、便座14及び便蓋16が上下方向回動可能に該便座ボックス12に取り付けられている。符号18はロータンクを示す。
【0003】
この便座ボックス12は側方に張り出す張出部20を備えており、この張出部20上に人体臀部を温水で洗浄する温水洗浄装置等の操作スイッチが設けられている。
【0004】
この便座ボックス12内に便蓋16を起倒回動させるためのモータ等の駆動装置が設けられており、張出部20にはこの駆動装置を作動させるべく人体検知センサ22が設けられている。
【0005】
この人体検知センサとしては赤外線センサ例えばPSD(position sensitive detector)などが用いられている。このPSDは、発光素子からセンサを発光させ、人体からの反射光をPSD素子上に集光させ、該PSD素子上の集光位置に基づいてセンサから人体までの距離を求めるようにしたものである。
【0006】
第4,5図に示すように、この人体検知センサ22の赤外線は洋風便器10の前方斜め上方、且つ洋風便器10の中央側に向って放射される。
【0007】
通常の場合、該センサ20は、人体が洋風便器10の前端付近までの距離Lminとそれよりも約300mm先までの距離Lmaxとの間の検知エリアに入り込むと人体検知信号を出力する。この信号の入力を受けた制御回路が便蓋駆動装置を駆動し、便蓋16が起立回動する。検知エリア内に人体が検知されなくなると、所定時間(例えば1分)経過後に便蓋18が自動的に閉止回動する。
【0008】
なお、便座14に着座した人体を検知する着座センサを設けておき、着座が検知されなくなってから所定時間後に便蓋18を自動的に閉止させることもある。
【0009】
【発明が解決しようとする課題】
トイレルームが狭い場合、洋風便器の前方300mm程度の位置に壁やドアが位置することがある。このような場合、従来の便蓋自動開閉装置付き洋風便器は、(壁又はドアが常に検知されるため)設置できないことになる。
【0010】
また、トイレルームが広い場合には、トイレルームに人が入った段階ですぐに便蓋が開くようにしたいことがあるが、従来の人体検知装置では人体が洋風便器に300mm程度にまで近づかないと便蓋が開かないという不便がある。
【0011】
本発明は、このような不便を解消し、人体検知エリアの境界を自ら設定しうる人体検知装置を用いた便器電装品を提供することを目的とする。
【0012】
【課題を解決するための手段】
本発明の便器電装品は、人体検知装置の人体検知信号により制御される便器電装品において、該人体検知装置は、検知エリア内の人体を検知する人体検知装置において、検知エリアの境界を徐々に変更し対象物が初めて検知又は不検知になったときの境界から所定の距離を減じた距離に基づいて検知エリアの上限値を設定する境界設定手段を設けたことを特徴とするものである
【0013】
【発明の実施の形態】
第1図は実施の形態に係る便蓋自動開閉装置のブロック図である。
【0014】
この便蓋自動開閉装置を備えた洋風便器の外観構成は前記第3図と同様であり、便座ボックスの張出部20に人体検知センサ22が設けられている。また、便座14又はその支持部に着座センサ24が設けられている。便座ボックス12の適宜の箇所例えば張出部20には、この人体検知センサ22の検知エリアの上限値を設定する検知エリア調節スイッチ26が設けられているが、このスイッチ26は単独に独立して設けられたものであってもよく、他の2個以上のスイッチ(例えば洗浄スイッチと乾燥スイッチ)を同時に押すこと等によって検知エリア調節信号を発生するものであってもよい。
【0015】
人体検知信号、着座信号及び検知エリア調節信号は制御回路28に入力され、この制御回路28によって便蓋16の回動用のモータ駆動回路30が制御される。
【0016】
この便蓋自動開閉装置においても、人体が人体検知センサ22の検知エリア内に入ると便蓋16が起立回動し、該エリア外に出ると便蓋16が倒伏回動する。また、便蓋16が起立した後、着座信号が入力し、その後着座が不検知になると所定時間(例えば1分)経過後に便蓋16が閉止回動する。
【0017】
検知エリア調節スイッチ26から検知エリア調節信号が入力された場合には第2図に示す制御が実行される。
【0018】
即ち、まず検知エリアの上限(最大距離)Lを十分に大きな値Lに設定する。このLは例えば1000mmとしたり、或いは人体検知センサ22の検知上限距離に設定される。
【0019】
そして、このL〜Lminの間に物体(例えばトイレルームの壁又はドア。なお、ドアの場合はドアを閉めておく。)が存在するか否かを判定する。Lを十分に大きな値としているので、通常は壁又はドアが検知される。そこで、次にLを10mmだけ短い距離に設定し、再度L〜Lminの間のエリアに壁やドアが検知されるか否かを判定する。このプロセスを壁やドアが検知されなくなるまで繰り返す。そして壁やドアが初めて検知されなくなったときのLから50mm減じた値をLmaxとして設定する。
【0020】
これにより、トイレルームが狭く壁やドアが洋風便器前方に近接している場合であっても便蓋自動開閉装置付き洋風便器を該トイレルームに設置することが可能となる。また、トイレルームが広い場合であってもトイレルームに入るとすぐに便蓋が開くようになる。
【0021】
この第2図にあってはLを徐々に減少させているが、逆にLをLmin(あるいはLminよりも少しだけ大きい値)から徐々に増大させてもよい。
【0022】
なお、第2図で例示した10mmや50mmはあくまでも一例であり、他の値であってもよいことは明らかである。
【0023】
また、第2図ではLmaxを1回の調節プロセスにて決定しているが、2回以上調節プロセスを繰り返し、それらの平均値などを採用してもよく、このようにすればLmaxを精度よく設定することができる。
【0024】
本発明は便蓋自動開閉装置以外の便器電装品例えば、便器の自動洗浄装置、又は脱臭装置或いは操作部等の自動照明などにも適用可能である。この自動洗浄装置は大便使用時、小便使用時のいずれでもよい。また、赤外線以外の超音波や可視光などによって距離を測定する人体検知装置も本発明適用できる。
【0025】
【発明の効果】
以上の通り、本発明によると検知エリアを自動的に設定しうる人体検知装置を用いた便器電装品が提供される。本発明によれば、例えば狭いトイレルームに便蓋自動開閉装置付きの洋風便器を設置したり、広いトイレルームであっても入室すると直ちに便蓋が開くように便蓋自動開閉装置を構成すること等が可能となる。

The toilet seat box 12 is provided with an overhanging portion 20 that protrudes to the side, and an operation switch such as a warm water washing device for washing the human body with warm water is provided on the overhanging portion 20.
[0004]
The toilet seat box 12 is provided with a driving device such as a motor for moving the toilet lid 16 up and down, and the overhanging portion 20 is provided with a human body detection sensor 22 for operating the driving device. .
[0005]
As this human body detection sensor, an infrared sensor such as a PSD (position sensitive detector) is used. In this PSD, the sensor emits light from the light emitting element, the reflected light from the human body is condensed on the PSD element, and the distance from the sensor to the human body is obtained based on the condensing position on the PSD element. is there.
[0006]
As shown in FIGS. 4 and 5, the infrared rays of the human body detection sensor 22 are radiated obliquely upward in front of the western style toilet 10 and toward the center of the western style toilet 10.
[0007]
In a normal case, the sensor 20 outputs a human body detection signal when the human body enters a detection area between a distance Lmin to the vicinity of the front end of the western-style toilet 10 and a distance Lmax about 300 mm ahead. Upon receiving this signal input, the control circuit drives the toilet lid driving device, and the toilet lid 16 is turned upright. When a human body is no longer detected in the detection area, the toilet lid 18 automatically rotates and closes after a predetermined time (for example, 1 minute) has elapsed.
[0008]
A seating sensor that detects a human body seated on the toilet seat 14 may be provided, and the toilet lid 18 may be automatically closed after a predetermined time after the seating is no longer detected.
[0009]
[Problems to be solved by the invention]
When the toilet room is small, a wall or door may be located at a position about 300 mm in front of the Western-style toilet. In such a case, the conventional Western style toilet with automatic toilet lid opening / closing device cannot be installed (because a wall or a door is always detected).
[0010]
Also, if the toilet room is large, you may want to open the toilet lid as soon as a person enters the toilet room. However, with a conventional human body detection device, the human body does not approach a Western-style toilet up to about 300 mm. There is an inconvenience that the toilet lid does not open.
[0011]
The present invention is to solve such inconveniences, and an object thereof is to provide a toilet electrical component with human body detection equipment capable of setting its own boundaries of the human body detection area.
[0012]
[Means for Solving the Problems]
The toilet electrical component of the present invention is a toilet electrical component controlled by a human body detection signal of the human body detection device, and the human body detection device gradually detects the boundary of the detection area in the human body detection device that detects the human body in the detection area. Boundary setting means is provided for setting an upper limit value of the detection area based on a distance obtained by subtracting a predetermined distance from the boundary when the object is detected or not detected for the first time .
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram of the engaging Ru flights lid automatic opening and closing apparatus according to the embodiment.
[0014]
The appearance of the Western-style toilet equipped with this toilet lid automatic opening / closing device is the same as that shown in FIG. 3, and a human body detection sensor 22 is provided on the overhanging portion 20 of the toilet seat box. Further, a seating sensor 24 is provided on the toilet seat 14 or a support portion thereof. A detection area adjustment switch 26 for setting an upper limit value of the detection area of the human body detection sensor 22 is provided at an appropriate portion of the toilet seat box 12, for example, the overhanging portion 20. The switch 26 is independently provided. The detection area adjustment signal may be generated by simultaneously pressing other two or more switches (for example, a washing switch and a drying switch).
[0015]
The human body detection signal, the seating signal, and the detection area adjustment signal are input to the control circuit 28, and the control circuit 28 controls the motor drive circuit 30 for rotating the toilet lid 16.
[0016]
Also in this toilet lid automatic opening and closing device, when the human body enters the detection area of the human body detection sensor 22, the toilet lid 16 pivots upright, and when it goes out of the area, the toilet lid 16 pivots down. Also, after the toilet lid 16 is erected, a seating signal is input, and when seating is not detected thereafter, the toilet lid 16 is turned and closed after a predetermined time (for example, 1 minute) has elapsed.
[0017]
When a detection area adjustment signal is input from the detection area adjustment switch 26, the control shown in FIG. 2 is executed.
[0018]
That is, first set to a large value L 0 sufficiently limit (maximum distance) L of the sensing area. This L 0 is set to 1000 mm, for example, or is set to the detection upper limit distance of the human body detection sensor 22.
[0019]
Then, it is determined whether or not there is an object (for example, a wall or door of a toilet room. In the case of a door, the door is closed) between L and Lmin. Since the L 0 is a sufficiently large value, usually Kabemata the door is detected. Therefore, next, L is set to a short distance by 10 mm, and it is determined again whether or not a wall or door is detected in the area between L and Lmin. This process is repeated until no walls or doors are detected. A value obtained by subtracting 50 mm from L when the wall or door is not detected for the first time is set as Lmax.
[0020]
Thereby, even when the toilet room is narrow and the wall and door are close to the front of the western style toilet, it is possible to install the western style toilet with an automatic toilet lid opening / closing device in the toilet room. Even if the toilet room is large, the toilet lid opens as soon as it enters the toilet room.
[0021]
In FIG. 2, L is gradually decreased, but conversely, L may be gradually increased from Lmin (or a value slightly larger than Lmin).
[0022]
It should be noted that 10 mm and 50 mm illustrated in FIG. 2 are merely examples, and other values are obvious.
[0023]
In FIG. 2, Lmax is determined by a single adjustment process, but the adjustment process may be repeated two or more times, and an average value thereof may be employed. In this way, Lmax can be accurately determined. Can be set.
[0024]
The present invention is also applicable to toilet electrical equipment other than the toilet lid automatic opening / closing device, for example, an automatic cleaning device for a toilet bowl, or automatic lighting for a deodorizing device or an operation unit. This automatic cleaning device may be used when using a stool or when using a urine. Also, the human body detection equipment for measuring the distance by ultrasonic or visible light other than infrared may be applied to the present invention.
[0025]
