産業上の利用分野
本発明は家庭用の風呂システムの状態表示方式
に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a status display system for a domestic bath system.
従来例の構成とその問題点
従来、家庭用風呂システムにおいて、浴槽部分
は、第１図のように浴槽部１と、蓋２によつて構
成されており、通常風呂を沸かすとき、あるい
は、使用済みのときには浴槽を蓋で覆つている。Conventional structure and its problems Conventionally, in a home bath system, the bathtub part is composed of a bathtub part 1 and a lid 2 as shown in Fig. 1. When the bath is finished, the bathtub is covered with a lid.
これは、放熱損失を少なくして省エネルギー効
果を高めるためである。 This is to reduce heat radiation loss and increase energy saving effect.
しかしながら、蓋は使用者の手によつて開閉す
るので、蓋を閉め忘れることが、しばしばあり、
使用者は、確認のために浴室に足を運ばねばなら
なかつた。 However, since the lid is opened and closed by the user's hands, the user often forgets to close the lid.
The user had to go to the bathroom to check.
発明の目的
本発明は、このような従来の問題点を解決する
ために、浴室から離れた場所においても、風呂蓋
の状態が確認できるシステムを実現することを目
的とする。OBJECTS OF THE INVENTION In order to solve these conventional problems, it is an object of the present invention to realize a system that allows the state of the bath lid to be checked even at a location away from the bathroom.
発明の構成
上記目的を達成するために、本発明は、浴槽内
の適当な場所に光検知素子を配置し、蓋の開閉に
伴なう明るさの変化を検出して表示するように構
成している。Structure of the Invention In order to achieve the above object, the present invention is configured to arrange a light detection element at an appropriate location in the bathtub, and to detect and display changes in brightness caused by opening and closing of the lid. ing.
実施例の説明
第２図において、３は光検知素子、４は比較回
路、VSは、あらかじめ設定してある基準信号値
である。５は表示部である。DESCRIPTION OF THE EMBODIMENTS In FIG. 2, 3 is a photodetecting element, 4 is a comparison circuit, and V S is a preset reference signal value. 5 is a display section.
上記構成において、光検知素子３は、浴槽１の
蓋２を開閉することによつて変化する光量の変化
を検知する。すなわち、蓋が閉じている時には、
浴槽内は暗状態であり、蓋を開くと明状態になる
が、この明暗の違いを電気信号EVに変換する。 In the above configuration, the light detection element 3 detects changes in the amount of light that change when the lid 2 of the bathtub 1 is opened and closed. In other words, when the lid is closed,
The inside of the bathtub is dark, and when the lid is opened it becomes bright, but this difference in brightness is converted into an electrical signal EV .
例えば、光検知素子としてフオト・ダイオード
を使用すると、明暗の変化は、電流の変化として
検出できる。この電気信号EVと基準信号VSとを
比較回路４によつて比較し、例えば蓋を開いたと
き、EV≧VSとなり、比較回路４の出力信号が、
導通状態となつて、表示部５を駆動する。すなわ
ち、蓋の開閉に対応して表示部５が自動的に点滅
することになる。 For example, if a photo diode is used as a light sensing element, a change in brightness can be detected as a change in current. The electric signal E V and the reference signal V S are compared by the comparator circuit 4. For example, when the lid is opened, E V ≧V S , and the output signal of the comparator circuit 4 is
It becomes conductive and drives the display section 5. That is, the display section 5 automatically blinks in response to opening and closing of the lid.
第３図は上記明暗検知機能の具体的な、実施例

てフオト・ダイオード、表示部５として、発光ダ
イオード、および、比較回路として電圧比較器を
使用した例である。R1は、フオト・ダイオード
の電流変化を電圧変化EVとして取り出すための
抵抗であり、R2は発光ダイオードの電流を制限
する抵抗、Ｖは動作電圧である。上記回路におい
て蓋が閉じていると、フオトダイオード３の暗電
流は非常に小さいのでEV＜VSとなり、電圧比較
器の出力は、“High”状態となり発光ダイオード
５は導通しない。蓋が開くと、EV≧VSとなり電
圧比較器４の出力は“Low”状態となり発光ダ
イオード５が導通し、点灯する。すなわち、蓋の
開閉に応じて、発光ダイオード５が点滅する。 FIG. 3 shows a specific example of the brightness detection function described above. In FIG. 3, a photo diode is used as the photodetecting element 3, a light emitting diode is used as the display section 5, and a voltage comparator is used as the comparison circuit. R 1 is a resistor for extracting the current change of the photo diode as a voltage change EV , R 2 is a resistor that limits the current of the light emitting diode, and V is the operating voltage. In the above circuit, when the lid is closed, the dark current of the photodiode 3 is very small, so that E V <V S , and the output of the voltage comparator becomes “High” and the light emitting diode 5 does not conduct. When the lid is opened, E V ≧V S and the output of the voltage comparator 4 becomes “Low”, making the light emitting diode 5 conductive and lighting up. That is, the light emitting diode 5 blinks in response to opening and closing of the lid.
フオトダイオード３は、浴槽１に取りつけられ
ており、信号線を延長すれば、上記回路は浴室か
ら離れた場所に置くことができる。 The photodiode 3 is attached to the bathtub 1, and by extending the signal line, the above circuit can be placed at a location away from the bathroom.
発明の効果
本発明によれば、浴室から離れた場所において
も、浴槽の蓋の開閉状態が判るので、
(1) 蓋の確認のためだけに浴室に足を運ばなくて
もよい。Effects of the Invention According to the present invention, it is possible to know whether the bathtub lid is open or closed even at a location away from the bathroom, so (1) there is no need to visit the bathroom just to check the lid.
(2) 蓋の開状態を入浴中と対応させれば、浴室以
外の場所で入浴中か、否かの判別が可能。(2) If the open state of the lid corresponds to bathing, it is possible to determine whether the person is bathing in a place other than the bathroom.
(3) 蓋の閉め忘れが防止できるので省エネルギー
効果が期待できる。(3) Since forgetting to close the lid can be prevented, energy-saving effects can be expected.
