Abstract

PURPOSE:To prevent a user from feeling an unpleasant odor by actuating an odor producing device and simultaneously starting the operation of a toilet ventilating fan when an infrared sensor detects a fact that the user enters a room. CONSTITUTION:Once a user enters a toilet 4, an infrared sensor 2 detects the fact and a control part 1 actuates an odor producing device 5 to produce an odor and simultaneously actuates a toilet ventilating fan 3. On the other hand, once the user goes out from the toilet 4, the control part 1 interrupts the odor producing device 5 and further operates the toilet ventilating fan 3 for a while and interrupts the same after the passage of a predetermined time. After the interruption of the toilet ventilating fan 3 the odor producing device 5 is gain actuated and is interrupted after the passage of a predetermined time. Hereby, there is achieved the ventilation where comfortable odor is produced when the user in the toilet without making the user feel unpleasant. Thus, a next user is prevented from feeling unpleasant, leaving behind comfortable odor after the user leaves the toilet.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic operating device for a ventilation fan installed in a toilet.

0002

[Prior Art] Conventionally, automatic operation devices for ventilation fans of this type are generally known as shown in Fig. 2, although no specific literature can be cited.
As shown in FIG. 2, the infrared sensor 102 detects that a user has entered the toilet 104, provides the detection signal to the control section 101, and the control section 101 turns on the ventilation fan 103.
When the user leaves the vehicle, the infrared sensor 102
The system was designed to operate for a certain amount of time from when the system no longer detected a user, that is, to operate slowly, and then to stop operating.

0003

[Problem to be Solved by the Invention] In such a conventional configuration, the odor immediately after entering the toilet is eliminated by the residual slow operation of the ventilation fan, which exhausts a considerable amount of the odor from the previous user, but it is not completely exhausted, and the odor is not completely absorbed from outside. For some users, it was impossible to get rid of the discomfort. Further, in order to exhaust the odor while the user is using the toilet, a large amount of air is required, which causes a lot of noise and causes discomfort.

[0004] The present invention is intended to solve these conventional problems, and an object of the present invention is to provide an automatic operation device for a toilet ventilation fan that efficiently ventilates the room and eliminates discomfort due to odors.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an infrared sensor that detects when a user enters the toilet and sends a signal, and a control that operates in response to the signal from the infrared sensor. the controller, a scent generator that generates a scent in response to a signal from the controller, and a toilet ventilation fan that operates; This automatic operating device for a toilet ventilation fan has a means for operating the ventilation fan in a residual delay, and a means for operating the scent generating device for a certain period of time after the toilet ventilation fan has stopped operating.

[0006]

[Operation] In this configuration, when a user enters the room, the infrared sensor detects it and sends a signal to the control unit, which activates the scent generator to generate scent and at the same time starts operating the toilet ventilation fan. When the user leaves the room and the signal from the infrared sensor stops, the control section stops the scent generator and causes the ventilation fan to remain in slow operation. Furthermore, when the residual slow operation of the ventilation fan ends, the fragrance generating device is operated again for a certain period of time.

[0007]

[Embodiment] An embodiment of the present invention will be described below with reference to FIG. As shown in the figure, for example, an infrared sensor 2 and a toilet ventilation fan 3 are installed on a ceiling surface 6 of a toilet 4 to detect when a user enters the room and output a signal. Also wall surface 7
A scent generating device 5 is installed at. The infrared sensor 2, the toilet ventilation fan 3, and the scent generator 5 are all connected to a control unit 1 that operates and stops the scent generator 5 and the toilet ventilation fan 3 by receiving and stopping the signals.

In the above configuration, when a user enters the toilet 4, the infrared sensor 2 detects the entry and sends a signal to the control unit 1, and the control unit 1 operates the scent generator 5 to generate a scent, and at the same time , the toilet ventilation fan 3 is operated. When the user exits the toilet 4, the infrared sensor 2 stops outputting a signal, the control unit 1 stops the fragrance generating device 5, and the toilet ventilation fan 3 is operated slowly for a certain period of time, and then stopped after the elapse of a certain period of time. After the toilet ventilation fan 3 is stopped, the fragrance generator 5 generates fragrance again and all operations are stopped after a certain period of time has elapsed.

By automatically controlling the operation of the toilet ventilation fan 3 and the scent generator 5 as described above, while the user is in the room, the odor caused by urination is exhausted and a pleasant scent is generated to the user. We provide ventilation that does not cause discomfort, and after the user leaves, we use residual odor to remove residual odors.
It leaves a pleasant scent and does not cause discomfort to the next user.

0010

[Effects of the Invention] As is clear from the above description of the embodiments, according to the present invention, an infrared sensor, a control unit, a scent generator, and a toilet ventilation fan are provided, and a scent is generated immediately after the user enters the room. Toilet ventilation can be improved by automatically operating the toilet ventilation fan, stopping the scent generation after leaving the room, leaving the toilet ventilation fan in slow operation, and automatically generating the scent for a certain period of time after the toilet ventilation fan is stopped. This can be done comfortably and efficiently, and the effect is that all users are free from unpleasant odors.
