Abstract

PURPOSE:To prevent a ventilating apparatus from being left ON or OFF carelessly and to ventilate a bathroom properly by a construction wherein a common terminal of an operation switch constructed of a three-way switch is connected to one pole of a power source, an ON terminal thereof to a ventilation fan and an OFF terminal thereof to a humidity sensor and a humidity sensing switch. CONSTITUTION:While an illumination switch element 6 of an operation switch 3 is provided for lighting an illuminator when a bathroom is employed, a ventilation switch element 5 is provided for operating a ventilation fan 1 when the bathroom is employed or after it is employed, and the ventilation fan 1 is always operated by pushing the element 5 onto the ON side. When it is pushed onto the OFF side, electrification of the ventilation fan 1 is disconnected, a humidity sensor 2 is connected to a power source 13 and this humidity sensor 12 detects humidity in the bathroom. When the humidity exceeds a prescribed value, a humidity sensing switch 4 is closed automatically and thereby the ventilation 1 is electrified and starts operation. Even when it is forgotten that the ventilation switch element 5 is put onto the OFF side, the ventilation fan 1 is stopped automatically when ventilation turns unnecessary, and in addition, it can be operated also at all times irrespective of humidity.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ventilation system for bathrooms in housing complexes such as condominiums.

Conventional technology Bathrooms in condominiums and other apartment complexes generally have high humidity and condensation tends to form on the walls. If left untreated, mold and mildew can form and the walls may rot.

Conventionally, such bathrooms have been provided with a ventilation system 100, as shown in FIGS. 4 to 6, to exhaust the moisture within the bathroom to the outside.

In addition, a lighting device 1o1 is installed in the bathroom, and a ventilation system 1.00 and lighting device 1 are connected by an operation switch 102 installed outside the bathroom.
01 were operated independently.

Problems to be Solved by the Invention In such a conventional configuration, when a user enters the bathroom, the user turns on the illuminator 101 or turns on the ventilation device 1oo.
In some cases, the user may forget to turn on or turn off the operation switch 102. In particular, the ventilation device 10o is more difficult to discern the energized state than the illuminator 101, so it is often the case that the operator forgets to turn on or turn off the operation switch 102.

The present invention is intended to solve these problems, and aims to eliminate the problem of forgetting to turn on or turn off a ventilation device, to properly ventilate a bathroom, and to efficiently discharge moisture.

Means for Solving the Problem In order to solve this problem, the present invention connects a first terminal, which is a common terminal of an operation switch consisting of a three-way switch, to one pole of a power supply, and connects a second terminal, which is an input terminal, to one terminal of a power supply. Connect the terminal directly to the ventilation fan, and connect the third terminal, which is the disconnected terminal, to the humidity sensor.
A humidity sensing switch that opens and closes in response to the operation of the humidity sensor and the series circuit of the ventilation fan are connected in parallel to one connection point, and the other connection point is connected to the other pole of the power source. It consists of a ventilation system.

Function: With this configuration, when the operation switch is operated and the common terminal is connected to the input terminal, the ventilation fan is energized and operates at all times. Then, when you switch the operation switch and connect the common terminal to the disconnected terminal, the humidity sensor detects the humidity, and if the humidity is lower than the predetermined value, the humidity sensor switch remains open and the ventilation fan is stopped, and the humidity reaches the predetermined value. When the humidity exceeds this value, the humidity sensor is activated, the humidity sensor switch is closed, and the ventilation fan automatically starts operating.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3.

As shown in Fig. 1, the basic configuration of the ventilation system of this embodiment includes a ventilation fan 1 installed in a bathroom of an apartment complex, a humidity sensor 2 connected to this ventilation fan 1, and a humidity sensor 2 installed on the wall outside the bathroom. It consists of an operation switch 3.

The details of this ventilation device will be explained below.

By the way, a lighting device 12 is also provided in the bathroom, and the operation switch 3 is connected to a ventilation switch section 5 and a lighting switch section 6.
It is composed of. The ventilation switch section 5 consists of a 3-way switch, with a common end +7° cut terminal8. It has three terminal parts including an input terminal 9.

On the other hand, the lighting switch section 6 consists of a two-way switch, with a common terminal 10. It has two terminal parts, an input terminal 11, and no cut terminal. The ventilation switch unit 5 has a common terminal +7 connected to one pole of the power supply 13, and a disconnect terminal 8 connected to the humidity sensor 2, a humidity sensing switch 4 that opens and closes in response to the operation of the humidity sensor 2, and a ventilation fan 1. The input terminal 9 is connected directly to the ventilation fan 1. Also, humidity sensor 2 and humidity sensing switch 4
- The other connection point of the parallel connection with the series circuit of ventilation fan 1 is
Connected to the other pole of the power supply. On the other hand, the lighting switch section 6 connects the common terminal 10 to one pole of the power supply 13 together with the common terminal 7 of the ventilation switch section, and connects the input terminal 11 to the illumination device 1.
2, and connect the lighting switch section 6 and illuminator 12 to the power source 1.
3 is connected in series to form a circuit.

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

The lighting switch section 6 of the operation switch 3 is used to turn on the lighting when the bathroom is in use, and is turned on when pushed to the on side as shown in FIG. 3, and turned off when pushed to the off side as shown in FIG. The ventilation switch section 5 operates the ventilation fan 1 when using the bathroom or after using the bathroom, and the ventilation fan 1 is always operated by pushing it toward the entrance side shown in FIG. 3.

When pressed to the off side, the power to the ventilation fan 1 is cut off, the humidity sensor 2 is connected to the power supply 13, the humidity sensor 12 detects the humidity in the bathroom, and when the humidity exceeds a predetermined value, it automatically The humidity sensing switch 4 is closed and the ventilation fan 1 is energized and starts operating.

As described above, according to the embodiment, even if you forget to turn the ventilation switch part 5 of the operation switch 3 to the on side, the ventilation fan 1 is automatically turned on quickly when ventilation is required, and the ventilation switch part 5 Forgetting to make the cut side.

However, when ventilation is no longer necessary, the ventilation fan 1 is automatically stopped, and can also be operated at all times regardless of humidity.

Effects of the Invention As is clear from the above description of the embodiments, the present invention has the so-called "off" function of the conventional switch for immediately operating the ventilation fan when one wants to ventilate, and the operation switch can be turned off. When you forget to turn it on or turn it off, the ventilation fan is automatically and appropriately operated depending on whether ventilation is necessary or not, and the effect of efficiently preventing mold growth due to insufficient ventilation can be obtained.
