産業上の利用分野
本発明は洗面所等、湿度の高い部屋の換気を行なうため
の自動換気装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic ventilation system for ventilating rooms with high humidity, such as washrooms.
従来の技術
従来、この種の換気装置は、たとえば第３図および第４
図に示すような構成であった。2. Prior Art Conventionally, ventilation systems of this type have been used, for example in FIGS. 3 and 4.
The configuration was as shown in the figure.
図には洗面所の場合を示し換気扇１ｏ１には吸込口１０
２と吐出口１０３とを有する外か＜１０４内に、吸込口
１０２と吐出口１０３を結び排気用送風機１０６を設け
た排気用通風路１０６が形成されている。そして、換気

湿度を検知し、電源回路１１２を開閉する湿度センサ１
０９と、手動用の運転スイッチ１１０が並列に接続され
ている。The figure shows the case of a washroom, and the ventilation fan 1o1 has 10 inlets.
An exhaust ventilation path 106 is formed outside the exhaust port 104 having the exhaust port 102 and the discharge port 103. The outlet 103 of the ventilation fan 101 is connected to the outdoor hood 10B by a vibrator 107. In addition, an exhaust blower 105
A humidity sensor 1 is connected to the power supply circuit 112 connected to the power supply 111 to detect the humidity in the washroom C and open/close the power supply circuit 112.
09 and a manual operation switch 110 are connected in parallel.
この構成により、たとえば、入浴時の浴室りからの蒸気
あるいは、洗濯時の湿気等によシ洗面所Ｃ内の湿度が上
昇し、換気の必要がある場合には、使用者が洗面所Ｃに
いなくても、湿度センサ１０９が洗面所Ｃ内の湿度の上
昇を検知して、運転スイッチ１１ｏが開の状態であって
も、換気扇１０１を運転させ、湿度が一定値以下に下が
れば、換気扇１０１を停止させることができる。With this configuration, for example, if the humidity in the washroom C increases due to steam from the bathroom during bathing or humidity during washing, and ventilation is required, the user can return to the washroom C. Even if the humidity sensor 109 detects an increase in the humidity in the washroom C, the ventilation fan 101 is operated even if the operation switch 11o is in the open state, and if the humidity falls below a certain value, the ventilation fan 101 is turned on. 101 can be stopped.
また、使用者ば洗面所Ｃにいるときは、湿度の高低にか
かわらず、使用の必要に応じて、運転スイノチ１１０を
開閉することによって運転および停止することができる
。Further, when the user is in the washroom C, the user can operate and stop the operation by opening and closing the operating switch 110 as necessary, regardless of the humidity level.
発明が解決しようとする問題点
このような従来の構成では、運転スイッチ１１０が開で
あっても、洗面所Ｃの湿度が基準値を越えれば、換気扇
１０１は動作する。したがって、冬季洗面所Ｃに人がい
るときに換気扇１０１を運転すると、洗面所Ｃ内への給
気によってコールドドラフトが発生するという問題があ
った。Problems to be Solved by the Invention In such a conventional configuration, even if the operation switch 110 is open, if the humidity in the washroom C exceeds a reference value, the ventilation fan 101 operates. Therefore, when the ventilation fan 101 is operated when there are people in the washroom C in winter, there is a problem in that cold drafts are generated by the air supplied into the washroom C.
本発明は上記従来の問題点に留意し、洗面所内に人がお
り、かつ換気扇を運転すると不具合な場合に、換気扇が
作動しない自動換気装置を提供することにある。The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide an automatic ventilation system in which the ventilation fan does not operate when there are people in the washroom and operating the ventilation fan would be inconvenient.
問題点を解決するための手段
この問題を解決するために本発明は、換気扇と、室内の
湿度を感知して前記換気扇の運転を制御する湿度センサ
と、前記室内の人体の有無を感知して前記換気扇の運転

動換気装置を構成したものである。Means for Solving the Problem In order to solve this problem, the present invention provides a ventilation fan, a humidity sensor that senses the humidity in the room and controls the operation of the ventilation fan, and a humidity sensor that senses the presence or absence of a human body in the room. An automatic ventilation system is constructed by connecting a human body detector that controls the operation of the ventilation fan in series to a power source.
作 用
この構成により、洗面所に人がいないときは、洗面所の

面所の湿度が基準値よりも低くなると停止する。洗面所
に人がいる場合は、人体検知器によって換気扇の電源回
路が開になり、洗面所内の湿度が基準値を越えても換気
扇は動作しないこととなる。With this configuration, when there is no one in the washroom, if the humidity in the washroom becomes higher than the standard value, the humidity sensor will detect the increase in humidity, the ventilation fan will operate, and the ventilation will bring the humidity in the washroom back to the standard value. It will stop when it becomes lower than the value. If there are people in the washroom, the human body detector will open the ventilation fan's power supply circuit, and the ventilation fan will not operate even if the humidity in the washroom exceeds a standard value.

接続した回路が設けられている。EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. This example shows the case of a washroom adjacent to a bathroom. In the figure, 1 is a ventilation fan, with an inlet 2 and an outlet 3.
An exhaust ventilation path 6 is provided in an outer shell 4 having an exhaust port 4, which connects the suction port 2 and the discharge port 3, and is provided with an exhaust blower 5. The outlet 3 of the ventilation fan 1 is connected to an outdoor hood 8 by a vibrator 7. In addition, in the power supply circuit 13 connecting the exhaust blower 6 to the power supply 12, there is a humidity sensor 10 that detects the humidity in the washroom A and opens and closes the power supply circuit 13, and a humidity sensor 10 that detects the presence or absence of a human body and similarly opens and closes the power supply circuit 13. A circuit in which a manual operation switch 9 is connected in parallel to a series circuit with the human body detector 11 is provided.
この構成により、洗面所Ａに人がいないときは、たとえ
ば浴室Ｂからの蒸気あるいは洗濯時の湿気により洗面所
Ａ内の湿度が高くなると、湿度センサ１ｏによって検知
され、換気扇１が動作する。With this configuration, when there is no one in the washroom A, if the humidity in the washroom A becomes high due to steam from the bathroom B or humidity during washing, the humidity sensor 1o detects this and the ventilation fan 1 is activated.
換気によって洗面所Ａ内の湿度が基準値よシも低くなる

換気扇１が動作することはなくなシ、冬季、洗面所Ａ内
への給気によってコールドドラフトが発生し不快を感じ
ることがなくなる。It will stop when the humidity in washroom A becomes lower than the standard value due to ventilation. On the other hand, if there is someone in the washroom A, the human body detector 11 opens the series circuit with the humidity sensor 10. Therefore, even if the humidity in the washroom A exceeds the standard value, if the operation switch 9 is open, the ventilation fan 1 will not operate. This means that cold drafts are no longer caused by the air being supplied into the washroom A during the winter season, and the user no longer feels uncomfortable.

果が得られる。Effects of the Invention As described above, according to the present invention, when the human body detector detects that there is no person in the washroom, when the humidity in the washroom becomes high, the humidity sensor detects this and the ventilation fan is activated to provide ventilation. When the humidity in the washroom becomes lower than the standard value, the fan will stop operating. On the other hand, if there is a person in the washroom, the circuit containing the humidity sensor will be opened by the human body detector, and the ventilation fan will not operate and the fan will stop operating if there is a person in the washroom. When a person is present, the ventilation fan will not operate independently of the person's will, and cold drafts will not occur during the winter when air is supplied into the washroom, resulting in effective and comfortable ventilation. can get.
