Abstract

PURPOSE:To eliminate the case in which a toilet user feels cold and unpleasant when he enters a toilet and make it possible to provide a pleasant and efficient ventilation by providing a control section which operates a ventilation fan for toilet in weak operation when a signal from an infrared ray sensor is received and operating retentively the ventilation fan in strong operation when the signal of the infrared ray sensor stops. CONSTITUTION:When a toilet user enters a toilet room 4, an infrared ray sensor 2 sends signal to a control section 1 to cause it to operate a toilet ventilation fan 3 in weak operation. When the toilet user leaves the toilet room 4 the infrared ray sensor 2 stops outputting the signal, and the control section 1 operates the toilet ventilation fan 3 retentively for a certain time in strong operation, and after a certain time has elapsed, the fan 3 is stopped. With this arrangement a toilet user does not feel cold and unpleasant by the discharged air in winter and after he has left the toilet, a pleasant end effective ventilation is provided.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は、トイレの換気を有効に行う換気扇の自動運転
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 operating device for a ventilation fan that effectively ventilates a toilet.

に使用者が入室したことを赤外線で検知してトイレ用換
気、扇を運転させ、使用者が退出して検知しなくなった
ときには、残遅運転を行うものであった。Conventional technology Conventionally, this type of automatic operation device for ventilation fans generally detects when a user enters the toilet using infrared rays to operate the ventilation fan for the toilet, and when the user leaves and the fan is no longer detected. , which operated with a residual delay.

発明が解決しようとする課題 このような従来の構成では、使用者の入室を検出したと
きも、退出後の残遅運転時も同じ風量の排気を行うため

じることがしばしば起こった。Problems to be Solved by the Invention In such a conventional configuration, in order to exhaust air at the same volume both when the user enters the room and when the user exits the room, the same amount of air is exhausted. It often occurred that the user felt cold and uncomfortable.

本発明はこのような課題を解決するもので、トイレに入
室中に使用者が寒くなく、快適な換気を行うことを目的
とするものである。The present invention is intended to solve these problems, and aims to provide comfortable ventilation so that the user does not feel cold while entering the toilet.

である。Means for Solving the Problem In order to solve this problem, the present invention includes an infrared sensor that detects when a user enters the toilet and sends a signal, and a system that turns off the toilet ventilation fan in response to the signal from the infrared sensor. The automatic operation device for a toilet ventilation fan is configured, and includes a control unit that causes the toilet ventilation fan to operate at high speed and remains in slow operation when the signal from the infrared sensor stops.

る。Function: With this configuration, when a user enters the toilet, the infrared sensor detects it and sends a signal to the control unit, which causes the ventilation fan to operate at low speed. Then, when the user leaves the room and the signal stops, the control section causes the ventilation fan to operate at high speed and at a low speed.

接続されている。EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. An infrared sensor 2 and a toilet ventilation fan 3 are installed on the ceiling of a toilet 4, for example, to detect that a user has entered the room and output a signal. Both the infrared sensor 2 and the toilet ventilation fan 3 are connected to a control unit 1 that controls the l/room ventilation fan 3 to operate in a weak mode, a strong mode, and a strong mode, and to stop it by receiving and stopping the signal.

転で残遅運転させ、一定時間経過後、停止させる。In the above configuration, when a user enters the toilet 4, the infrared sensor 2 detects this entry, sends a signal to the control unit 1, and the control unit 1 causes the toilet ventilation fan 3 to operate at low speed. When the user exits the toilet 4, the infrared sensor 2 stops outputting a signal, and the control unit 1 causes the toilet ventilation fan 3 to operate strongly and slowly for a certain period of time, and after a certain period of time, stops.

以上のように実施例によれば、使用者が入室中は弱運転
するので、冬期に排気によって寒く、不快に感じること
がなく、また、退出後に強運転で強力に排気するので、
快適にかつ有効な換気を行うことができることとなる。As described above, according to the embodiment, since the operation is performed at low speed while the user is entering the room, the user does not feel cold or uncomfortable due to the exhaust air in winter, and after leaving the room, the operation is performed at high power to exhaust the air powerfully.
This allows for comfortable and effective ventilation.
