Description

本発明は、検出範囲内に手等の物体が近づいたことを検出して被制御機器をONからOFF、またはOFFからONに制御する光電スイッチに関する。   The present invention relates to a photoelectric switch that detects that an object such as a hand has approached a detection range and controls a controlled device from ON to OFF or from OFF to ON.

化粧室や浴室等に設けられた機器において、スイッチを操作する手が濡れている可能性が高い場合、スイッチから水が浸入しない構造が要求される。
近年では、例えば洗面化粧台の照明や曇り止めヒータ等の被制御機器をONまたはOFFに制御するスイッチとして、水がかからない鏡体の裏面から表面に向けた光電スイッチを設け、当該光電スイッチの前に手をかざして照明または曇り止めヒータ等をONまたはOFFに制御している。なお、当該光電スイッチを設ける位置では、鏡体の反射膜を除去している。
In a device provided in a restroom, bathroom, or the like, when there is a high possibility that the hand operating the switch is wet, a structure in which water does not enter from the switch is required.
In recent years, for example, as a switch for controlling ON / OFF of controlled devices such as a bathroom vanity lamp and a fogging heater, a photoelectric switch is provided from the back to the surface of a mirror body that is not exposed to water. Hold the hand over to control the lighting or anti-fog heater etc. ON or OFF. Note that the reflective film of the mirror body is removed at the position where the photoelectric switch is provided.

また、光電スイッチは、その動作状態を利用者に認識させることが非常に重要であり、LED等の照明手段を用いてスイッチ名称または記号等を描出させている。
従来の光電スイッチでは、上記の照明手段を用いて、例えば曇り止めヒータをONに制御している場合は上記のスイッチ名称または記号等を緑色に点灯表示させ、曇り止めヒータをOFFに制御している場合は上記の照明手段を消灯させている。
しかし、夜間のように周囲が暗い場合、例えば利用者が洗面化粧台の照明をOFFからONにすることを所望しても、照明手段が消灯されていては光電スイッチの位置を探すことに手間がかかり、不便である。
そこで、特許文献1に記載された従来技術では、光電スイッチの位置を認識させるために発光素子を用いてスイッチ名称または記号等を描出させ、当該発光素子に3色LEDや複数の単色LEDを用い、その色で動作状態を示す(ON状態では緑色に発光させ、OFF状態では赤色に発光させる)構成が提案されている。この構成であれば、被制御機器がOFF状態であっても、発光素子の点灯(赤色点灯)により、暗い環境であっても光電スイッチの位置を認識することができる。
特開2004−355867号公報
In addition, it is very important for the photoelectric switch to let the user recognize its operating state, and the switch name or symbol is drawn using illumination means such as an LED.
In a conventional photoelectric switch, when the above-mentioned illumination means is used, for example, when the anti-fogging heater is controlled to be ON, the above switch name or symbol is lit in green, and the anti-fogging heater is controlled to be OFF. If there is, the lighting means is turned off.
However, when the surroundings are dark, such as at night, for example, even if the user desires to turn on the vanity from OFF to ON, it is troublesome to find the position of the photoelectric switch if the illumination means is turned off. It is inconvenient.
Therefore, in the prior art described in Patent Document 1, a switch name or a symbol is drawn using a light emitting element to recognize the position of the photoelectric switch, and a three-color LED or a plurality of single-color LEDs are used for the light-emitting element. A configuration has been proposed in which the operating state is indicated by the color (green light is emitted in the ON state and red light is emitted in the OFF state). With this configuration, even when the controlled device is in an OFF state, the position of the photoelectric switch can be recognized even in a dark environment by turning on the light emitting element (red lighting).
JP 2004-355867 A

しかしながら、特許文献1に記載された従来技術では、緑色の発光状態がON状態であり、赤色の発光状態がOFF状態であっても、利用者が、緑色はOFF状態、赤色はON状態と勘違いする可能性が高い。一般的な家庭用の電化製品において、ON状態が赤色で表示されるもの、あるいはON状態が緑色で表示されるもの、どちらも多く存在する。
例えば、利用者が「ON状態は赤色」と勘違いした場合、利用者は緑色の発光状態にてスイッチがOFFされた、と勘違いしてしまうため、利用されないにもかかわらず曇り止めヒータの電源が入った状態で放置されることとなる。
本発明は、このような点に鑑みて創案されたものであり、利用者が光電スイッチによる被制御機器のON状態とOFF状態とのそれぞれを、より確実に認識できるとともに、暗い環境であっても光電スイッチの位置を適切に認識させることが可能な光電スイッチを提供することを課題とする。
However, in the prior art described in Patent Document 1, even if the green light emission state is the ON state and the red light emission state is the OFF state, the user misunderstands that the green state is the OFF state and the red state is the ON state. There is a high possibility of doing. In general household appliances, there are many types of appliances whose ON state is displayed in red and those whose ON state is displayed in green.
For example, if the user misunderstands that “ON state is red”, the user misunderstands that the switch is turned off in the green light emitting state. It will be left in the state of entering.
The present invention was devised in view of such points, and allows the user to more reliably recognize the ON state and the OFF state of the controlled device by the photoelectric switch, and is a dark environment. It is another object of the present invention to provide a photoelectric switch that can appropriately recognize the position of the photoelectric switch.

● [Appearance of switch unit 40 (FIG. 2)]
Next, an example of the appearance of the switch unit 40 will be described with reference to FIG.
FIG. 2 shows a front view (left view) of the switch unit 40 and an AA sectional view (right view) as seen from the AA direction in the front view.
The switch unit 40 described in the present embodiment includes a switch that controls ON and OFF of the dressing table lighting 20 and the anti-fogging heater 30.

●[光電スイッチ50の構成(図3)と動作波形(図4)]
次に、図3を用いて光電スイッチ50の構成の例について説明する。なお、図3に示す例では、投光素子52A〜受光素子53B等のインターフェースを省略しており、この構成に限定されるものではない。
光電スイッチ50は、制御手段としてCPU51を備えている。

そして、CPU51は、曇り止めヒータ30の制御状態に合致するように照明手段53D(この例では、LED)を制御する。この場合、CPU51は、曇り止めヒータ30をOFF状態からON状態に制御すると、第1の輝度にて照明手段53Dを制御する。また、CPU51は、曇り止めヒータ30をON状態からOFF状態に制御すると、以下の(1)〜(3)に示すいずれかの制御方法にて照明手段53Dを制御することで、照明手段53Dによる照明の色彩を変更することなく、利用者に「OFF状態」であることをより確実に認識させることができる。
● [Configuration of photoelectric switch 50 (FIG. 3) and operation waveform (FIG. 4)]
Next, an example of the configuration of the photoelectric switch 50 will be described with reference to FIG. In the example shown in FIG. 3, interfaces such as the light projecting element 52A to the light receiving element 53B are omitted, and the present invention is not limited to this configuration.
The photoelectric switch 50 includes a CPU 51 as control means.
First, the case of the anti-fogging heater 30 will be described. The CPU 51 projects detection light from the light projecting element 53A, receives a detection signal from the light receiving element 53B, and detects an object such as a hand held by the user in the vicinity of the light projecting element 53A and the light receiving element 53B. Then, it is detected that an operation instruction for the anti-fogging heater 30 has been input. When the CPU 51 detects the operation instruction, the CPU 51 controls the fogging heater 30 to the ON state through the interface 53R such as a relay or an inverter circuit, and controls the switch to the OFF state when the fogging heater 30 is in the ON state. .
Then, the CPU 51 controls the illumination unit 53D (LED in this example) so as to match the control state of the anti-fogging heater 30. In this case, when the CPU 51 controls the anti-fogging heater 30 from the OFF state to the ON state, the CPU 51 controls the illumination unit 53D with the first luminance. Further, when the CPU 51 controls the anti-fogging heater 30 from the ON state to the OFF state, the CPU 51 controls the illumination unit 53D by any one of the following control methods (1) to (3). It is possible to make the user more surely recognize that the user is in the “OFF state” without changing the color of the illumination.

なお、以下の(1)〜(3)は、周囲が暗い場合を想定しており、ヒータ操作検出窓44の存在位置を利用者に認知させるために、照明手段53Dを消灯状態にすることなく、OFF状態であることを示す点灯状態(点滅状態も含む)にするものである。
(1)第1の輝度よりも低い第2の輝度で照明手段53Dを点灯する。
(2)第1の輝度よりも低い第2の輝度で照明手段53Dを点滅する。
(3)第1の輝度にて照明手段53Dを点滅する。
上記の(1)の制御方法の例を、図4(A)における「夜間」の期間における「LED照明」の「点灯(減光)」にて示す。この場合、図3における出力インターフェース53T(この例ではトランジスタ)にて、周期T1(例えば数ms〜数10ms程度)にて照明手段53DのONとOFFを繰り返す。ONデューティ(Don)を調整することで、第2の輝度の明るさを調整することができる。
また、上記の(2)の制御方法の例を、図4(B)における「夜間」の期間における「LED照明」の「点灯(減光)」と「消灯」にて示す。この場合、時間T2の期間(例えば1sec程度)での周期T1のデューティ出力と、時間T3の期間(例えば2sec程度)での消灯とを交互に実行する。
また、上記の(3)の制御の例は図示省略するが、時間T2の期間での点灯制御(継続的な点灯)と、時間T3の期間での消灯とを交互に実行すればよい。
Note that the following (1) to (3) are based on the assumption that the surroundings are dark, and the lighting means 53D is not turned off in order to make the user recognize the position of the heater operation detection window 44. The lighting state (including the blinking state) indicating the OFF state is set.
(1) The illumination unit 53D is turned on with a second luminance lower than the first luminance.
(2) The illumination unit 53D blinks at a second luminance lower than the first luminance.
(3) The illumination unit 53D blinks at the first luminance.
An example of the above control method (1) is indicated by “lighting (dimming)” of “LED illumination” in the “nighttime” period in FIG. In this case, the illumination means 53D is repeatedly turned on and off at a cycle T1 (for example, about several ms to several tens of ms) at the output interface 53T (a transistor in this example) in FIG. The brightness of the second luminance can be adjusted by adjusting the ON duty (Don).
In addition, an example of the control method (2) is indicated by “lighting (darkening)” and “lighting off” of “LED illumination” in the “nighttime” period in FIG. In this case, the duty output of the period T1 in the period of time T2 (for example, about 1 sec) and the turn-off in the period of time T3 (for example, about 2 sec) are executed alternately.
Although the example of the control (3) is not shown in the drawing, the lighting control (continuous lighting) during the period of time T2 and the lighting out during the period of time T3 may be executed alternately.

上記の(1)の制御を行った場合、利用者は、照明手段53Dによるヒータ動作表示窓43の照明の輝度が第1の輝度から第2の輝度に低下したことで、曇り止めヒータ30がOFF状態になったことを誤解なく確実に認識することができる。また、周囲が暗い環境であっても、第2の輝度でヒータ動作表示窓43を点灯させるので、利用者はヒータ操作検出窓44の存在位置を容易に認識することができる。
上記の(2)の制御を行った場合、利用者は、照明手段53Dによるヒータ動作表示窓43の照明の輝度が第1の輝度から第2の輝度に低下し、更に点滅状態となったことで、曇り止めヒータ30がOFF状態になったことを誤解なく確実に認識することができる。また、周囲が暗い環境であっても、第2の輝度でヒータ動作表示窓43を点滅させるので、利用者はヒータ操作検出窓44の存在位置を容易に認識することができる。
上記の(3)の制御を行った場合、利用者は、照明手段53Dによるヒータ動作表示窓43の照明が点灯状態から点滅状態となったことで、曇り止めヒータ30がOFF状態になったことを誤解なく確実に認識することができる。また、周囲が暗い環境であっても、ヒータ動作表示窓43を点滅させるので、利用者はヒータ操作検出窓44の存在位置を容易に認識することができる。
なお、化粧台用照明20に関する投光素子52A、受光素子52B、照明手段52D、インターフェース52T及び52R、照明動作表示窓41、照明操作検出窓42の場合も同様であるので、化粧台用照明20に関する説明は省略する。
When the above control (1) is performed, the user reduces the illuminance of the heater operation display window 43 by the illumination unit 53D from the first luminance to the second luminance. It can be surely recognized without misunderstanding that the vehicle is in the OFF state. Further, since the heater operation display window 43 is turned on with the second luminance even in a dark environment, the user can easily recognize the position of the heater operation detection window 44.
When the above control (2) is performed, the user has reduced the luminance of the illumination of the heater operation display window 43 by the illumination unit 53D from the first luminance to the second luminance, and has further entered a blinking state. Thus, it can be surely recognized without misunderstanding that the anti-fogging heater 30 has been turned off. Further, even in an environment where the surroundings are dark, the heater operation display window 43 blinks at the second luminance, so that the user can easily recognize the position of the heater operation detection window 44.
When the above control (3) is performed, the user has turned off the anti-fogging heater 30 because the illumination of the heater operation display window 43 by the illumination unit 53D has changed from a lighting state to a blinking state. Can be reliably recognized without misunderstanding. Further, since the heater operation display window 43 blinks even in an environment where the surrounding is dark, the user can easily recognize the position of the heater operation detection window 44.
The same applies to the light projecting element 52A, the light receiving element 52B, the illumination means 52D, the interfaces 52T and 52R, the illumination operation display window 41, and the illumination operation detection window 42 related to the dressing table lighting 20, and therefore the dressing table lighting 20 The description regarding is omitted.

上記の(1)〜(3)の制御は、周囲が暗い環境である場合を想定し、被制御機器をOFF状態に制御した場合であっても、利用者に照明操作検出窓42、ヒータ操作検出窓44の存在位置を認識させるために、照明動作表示窓41とヒータ動作表示窓43を上記の(1)〜(3)に示す点灯状態(点滅状態を含む)にした。しかし、周囲が明るい環境である場合は、被制御機器をOFF状態に制御した際、図4(A)及び(B)の「昼間」の期間における「LED照明」の「消灯」に示すように、照明動作表示窓41とヒータ動作表示窓43を消灯してもよい。もちろん、周囲が明るい環境であっても、上記の(1)〜(3)に示す点灯状態(点滅状態を含む)に制御してもよい。
図3に示すように、CPU51は、図2に示す照度検出窓45に設けられた照度検出手段54(昼夜識別手段に相当)の検出信号に基づいて照度を認識可能であり、認識した照度に基づいて現在が「夜間」であるのか「昼間」であるのかを認識することができる。
なお、照度検出窓45及び照度検出手段54を省略し、時刻を認識可能なタイマ手段(昼夜識別手段に相当)を用いて「昼間」と「夜間」を認識することもできる。この場合、CPU51は、内部あるいは外部のタイマ(図示省略)を用いて現在時刻を認識し、認識した時刻に基づいて現在が「夜間」であるのか「昼間」であるのかを認識することができる。
The above controls (1) to (3) assume that the environment is dark, and even if the controlled device is controlled to be in the OFF state, the user can operate the lighting operation detection window 42 and the heater operation. In order to recognize the existence position of the detection window 44, the illumination operation display window 41 and the heater operation display window 43 are turned on (including the blinking state) shown in the above (1) to (3). However, when the environment is bright, when the controlled device is controlled to be in the OFF state, as shown in “OFF” of “LED illumination” in the “daytime” period of FIGS. 4 (A) and 4 (B). The lighting operation display window 41 and the heater operation display window 43 may be turned off. Of course, even in an environment where the surroundings are bright, the lighting states (including the blinking state) shown in the above (1) to (3) may be controlled.
As shown in FIG. 3, the CPU 51 can recognize the illuminance based on the detection signal of the illuminance detection means 54 (corresponding to day / night identification means) provided in the illuminance detection window 45 shown in FIG. Based on this, it is possible to recognize whether the present time is “night” or “daytime”.
Note that the illuminance detection window 45 and the illuminance detection means 54 may be omitted, and “daytime” and “nighttime” may be recognized using timer means (corresponding to day / night identification means) capable of recognizing time. In this case, the CPU 51 can recognize the current time using an internal or external timer (not shown), and can recognize whether the current time is “night” or “daytime” based on the recognized time. .
