Abstract

PURPOSE:To perform ventilation assuredly and without waste by a method wherein an exhaust fan is provided in such a manner that the exhaust fan is interlocked with the operation of a humidity sensor which becomes non- connected and connected conditions accompanying with the on and off controls of a lighting switch. CONSTITUTION:When a person turns off a light at the time of leaving a bathroom A, a common terminal 7 of a lighting switch 4 is connected to an OFF side terminal 9, and voltage is connected to a humidity sensor 5. The humidity sensor 5 senses high humidity right after a bathing and operates, and a switch 10 becomes under an ON condition, being interlocked with this operation, and an exhaust fan 1 starts operating. When the inside of the bathroom A becomes not more than a designated humidity level, the operation of the humidity sensor 5 stops, and the switch 10 becomes under an OFF condition, and the exhaust fan 1 automatically stops. Therefore, while a bather does not need to pay special attention to the operation and stop of the exhaust fan 1, operation and stop are assuredly performed accompanying with lighting and putting out operations of a lighting apparatus 2, and forgetting to turn on or turn off the exhaust fan 1 is prevented from happening.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a ventilation system for a bathroom in an apartment complex such as Mansigon.

BACKGROUND OF THE INVENTION Bathrooms in condominiums and other housing complexes are highly airtight, and in such places, it is common practice to install a ventilation fan to exhaust the moisture outside. In this type of ventilation system, as shown in FIGS. 3 and 4, a bather turns on and off a ventilation fan 100 installed in bathroom B through a ventilation fan 101 installed near the entrance outside bathroom B. It was operated by At the same time, a lighting device 102 is also required in the bathroom, so like the ventilation fan 100, the user turns it off using the lighting switch 103.

Problems to be Solved by the Invention In such a conventional configuration, the ventilation fan 100, the illuminator 10
In both cases, the user had to operate the ventilation switch 101 and the lighting switch 103 each time. The illuminator 102 is easy for bathers to understand whether it is on or off.
There were relatively few cases of forgetting to operate the ventilation fan 100 due to the awareness of saving electricity, but since it was difficult for the user to know when to start and stop the ventilation fan 100, there were no cases of forgetting to turn it on or turn it off.
To prevent this, if you take a bath after turning on the ventilation switch 101, it will be cold, and if you turn off the ventilation switch 101 immediately after leaving the room, the humidity will increase due to poor ventilation, and mold will grow due to condensation on the walls. Proper ventilation was not possible.

The present invention is intended to solve these problems, and aims to provide reliable and efficient ventilation without the need for the bather to pay attention.

Means for Solving the Problem In order to solve this problem, the present invention provides a ventilation switch connected to a power supply, a ventilation fan operated by operation of the ventilation switch, and a lighting switch connected to an inlet terminal of a three-way contact. A ventilation system comprising: an illuminator, a humidity sensor connected to an open terminal; and a humidity sensor connected between the open terminal and a ventilation fan, which is connected to the operation of the humidity sensor. It is structured as follows.

With this configuration, when you turn on the light switch and turn on the illuminator when you take a bath, the ventilation fan remains off, and when you turn off the light switch and turn off the light when you leave the room, the humidity sensor detects high humidity. The ventilation fan is operated by operating the switch, and when the humidity falls below a predetermined value, the ventilation fan is automatically stopped. In addition to the above, the ventilation fan can be started and stopped manually by operating the ventilation switch.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in Fig. 1, the general configuration of the ventilation system of the embodiment includes a ventilation fan 1 and a lighting device 2 installed in a bathroom A of an apartment complex, and a ventilation fan 1 and a lighting device 2 installed near the entrance outside the bathroom A in order to turn them on and off. It consists of a ventilation switch 3 and a lighting switch 4 provided, and a humidity sensor 6 that senses the humidity in the bathroom A and automatically operates the ventilation fan 1.

Hereinafter, the detailed configuration of this ventilation system will be explained based on FIG. 2. Ventilation switch 3 connects ventilation fan 1 and power supply 6
is connected between. On the other hand, the light switch 4 is
The common terminal 7 of the road contact is connected to the power source 6, and the inlet side terminal 8 is connected to the illuminator 2.
In addition, the cut side terminal 9 is connected to the humidity sensor 6, respectively. Further, a switch 1o that opens and closes in conjunction with the operation of the humidity sensor 6 is connected between the off-side terminal 9 and the ventilation fan 1.

The operation of the ventilation system having the above configuration will be explained below.

The ventilation fan 1 can be operated normally manually by the ventilation fan 3.
This can be done by a single person, and it can be started and stopped instantly.

By the way, when taking a bath, the lighting device 2 is generally turned on, and at this time, the common terminal 7 of the lighting switch 4 is connected to the entrance terminal 8, and the ventilation fan 1 remains stopped.

Therefore, bathers do not feel cold and uncomfortable due to the operation of the ventilation fan 1, especially in winter. And bathroom A
When the light is turned off when leaving the room, the common terminal 7 of the lighting switch 4 is connected to the off-side terminal 9, and electricity is energized across the humidity sensor. The humidity sensor 6 is activated by sensing high humidity immediately after bathing, and in conjunction with this activation, the switch 10 is turned on. The ventilation fan 1 starts operating. When the humidity in the bathroom A falls below a predetermined humidity, the humidity sensor 6 stops operating, the humidity sensor 10 turns off, and the ventilation fan 1 automatically stops. Therefore, even if the bather does not have to be particularly careful about starting and stopping the ventilation fan 1, the lighting device 2 can be turned on and off reliably, and there is no need to forget to turn on or turn off the ventilation fan 1.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the ventilation fan is operated in conjunction with the operation of the humidity sensor which becomes non-conductive and conductive as the light switch is turned on and off. Even if you turn off the ventilation fan while taking a bath, you won't have to forget to turn it on after you leave the room. This will surely prevent the growth of mold due to condensation on the walls, and you will not be wasting energy by forgetting to turn off the ventilation fan. The effect is that it can be eliminated.
