Description

TECHNICAL FIELD The present invention relates to a ventilation device for a building.

[Conventional technology]

2. Description of the Related Art Conventionally, there is a ventilator that detects humidity in a room of a house, compares the detected humidity with a preset humidity, and drives or stops a ventilation fan. In this type of ventilation device, normally, as shown in FIG. 3, the humidity detecting element 1a is arranged near the ventilation fan 5, or the humidity detecting element is arranged in the ventilation fan 5.
I was incorporating 1a.

[Problems to be Solved by the Invention]

By the way, on the second floor of a house, dew condensation may occur even though there is no moisture source in any room. As a cause of this, in the case of a general house, it is conceivable that water vapor generated from the kitchen, sanitary (around the bathroom), etc. on the first floor enters each room on the second floor through the stairs as a passage.
In such a case, in the conventional ventilation device as described above,
When the humidity was detected, a considerable amount of water vapor had already entered the rooms on the second floor through the stairs, and there was a risk of dew condensation, which was not effective.

The present invention has been made in view of such circumstances,
An object of the present invention is to provide a ventilation device that can effectively prevent dew condensation on the upper floor when there is a moisture source on the lower floor.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention configures a ventilation device as in (1) below.

(1) Humidity detecting means having a humidity detecting element arranged near the start of climbing stairs in a building, humidity setting means for setting the humidity at the start / stop of ventilation, and the humidity detected by the humidity detecting means and the humidity A comparison determination unit that compares the humidity set by the setting unit and determines whether to start or stop ventilation, and the comparison determination unit that is installed near the stairwell or the climbing of the stairs, and is driven according to the output of the comparison determination unit. Or a ventilator with a ventilation fan to stop.

[Action]

According to the configuration of (1), the drive and stop of the ventilation fan are controlled according to the humidity near the start of climbing the stairs.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to Examples. FIG. 1 is a humidity detecting element of a "ventilator" which is an embodiment of the present invention.
FIG. 2 is a layout diagram of a ventilation fan, and FIG. 2 is a configuration diagram of the same embodiment.

In FIG. 1, 1a is a humidity detecting element of the humidity detecting unit 1 arranged at a position 1.2m above the first floor near the beginning 6a of the stairs 6, and 5 is the second floor near the ascending stairs 6b. It is a ventilation fan installed 0.5m from the ceiling.

The overall structure of the ventilator is as shown in Fig. 2.
1 is a humidity detecting unit that detects the humidity by the output of the humidity detecting element 1a, 3 is a humidity setting unit that sets the humidity at the start and stop of ventilation, 5 is a ventilation fan, 2 is the humidity and humidity setting unit of the humidity detecting unit 1. 3 is a comparison / determination unit that compares the set humidity of 3 and determines whether to drive or stop the ventilation fan 5. Reference numeral 4 denotes a load control unit that drives or stops the ventilation fan 5 that is a load according to a signal from the comparison determination unit 2.

 Next, the operation will be described.

The relationship between the detected humidity detected based on the signal from the humidity detecting element 1a and the set humidity set by the humidity setting unit 3 is
When the detected humidity reaches the set humidity, the comparison determination unit 2 determines the start of ventilation and starts driving the ventilation fan 5 via the load control unit 4. As a result, when the humidity on the second floor decreases and the detected humidity becomes less than the set humidity, the comparison and determination unit 2 determines whether to stop ventilation, and stops driving the ventilation fan 5 via the load control unit 4.

In this way, water vapor from the kitchen and sanitary on the first floor reaches the second floor through the stairs, and ventilation is performed before the humidity of each room on the second floor rises, preventing condensation on each room on the second floor. it can.

By the way, in the conventional example, when operating at a set humidity of 60%, the humidity of each room on the second floor was up to 70% after the start of operation.
However, in this example, when operating at the set humidity of 60%, the humidity of each room on the second floor could be kept below 60% at all times. .

In addition, although the above-mentioned embodiment is a ventilation device that extends over the first floor and the second floor, the present invention is not limited to this.
It may be a ventilation device that extends over the second and third floors, or a ventilation device that extends over the first and third floors.

The location of the ventilation fan is not limited to the vicinity of the stairs, and may be attached to the stairwell.

In addition, it can be implemented not only in a house but also in another building.

〔The invention's effect〕

As described above, according to the present invention, it is possible to effectively prevent dew condensation in each room on the upper floor when the stairs in the building serve as a passage for moisture.
