るものであった。2. Description of the Related Art Conventionally, an automatic ventilator detects humidity with a dew condensation sensor in a bathroom to operate and stop a ventilation fan. As shown in FIG. 2, the characteristic of the dew condensation sensor is that the resistance value changes with the change of humidity. And the operation of this device, set the reference humidity to a predetermined value (point A in Figure 2),
When the humidity exceeds the standard humidity, the ventilation fan is operated, and when it is below the standard humidity, the ventilation fan is stopped. In the winter, the user feels cold as the ventilation fan operates while taking a bath, so the power was turned on after bathing to start automatic operation.

いう不都合なことがあった。Problems to be Solved by the Invention In such a conventional configuration, there is a malfunction of detecting the atmospheric humidity other than in the bathroom and operating the ventilation fan in the case of rain, and in order to prevent it, the high humidity detection setting is performed. I often left it. In addition, when the user turns on the power after bathing in the winter, it is not always immediately after bathing, but for example, it is often put in several hours after the end of bathing before going to bed. At that time, water drops may remain on the wall surface in the bathroom. Nevertheless, there was a problem in that the vicinity of the dew condensation sensor was dried, the detected humidity became lower than the reference humidity, and the ventilation fan was not operated and sufficient ventilation could not be performed.
本発明はこのような課題を解決するもので、電源投入

行うことができること目的とするものである。The present invention solves such a problem, and after the power is turned on, even if the vicinity of the dew condensation sensor is dried, the ventilation fan is operated when the bathroom is not sufficiently dried to sufficiently dry the wall surface and the like. The purpose is to be able to do it.

るように構成したものである。Means for Solving the Problem In order to solve this problem, the present invention corresponds to a dew condensation sensor that detects a humidity in a bathroom and sends a signal, and a reference humidity that is preset by receiving a signal from the dew sensor. It has a control unit that operates or stops the ventilation fan in the bathroom,
After the power is turned on, the reference humidity is lowered by a fixed value for a fixed time.
作用 この構成により、電源投入後一定時間は基準湿度が低
くなり、これを基準にして換気扇は運転、あるいは停止
されることとなる。Action With this configuration, the reference humidity becomes low for a certain time after the power is turned on, and the ventilation fan is operated or stopped based on this.
実 施 例 以下、本発明の一実施例を第１図にもとづき説明す
る。Embodiment An embodiment of the present invention will be described below with reference to FIG.
浴室４内のたとえば天井面５に湿度を検知して信号を

６は電源の入・切を行うスイッチである。また制御部２
は壁面スイッチ６を通して電源と天井埋込換気扇３に接
続されている。A dew condensation sensor 1 that detects humidity and outputs a signal, for example, on the ceiling surface 5 in the bathroom 4, a control unit 2 that incorporates this dew condensation sensor 1, and a ceiling-embedded ventilation fan 3 are installed, and a wall surface outside the bathroom 4 is provided. The wall switch 6 is attached to the. Control unit 2
Receives the signal from the dew condensation sensor 1 and operates or stops the ceiling-mounted ventilation fan 3 in accordance with a preset reference humidity, and a setting switch 7 for setting the reference humidity to a desired value by the user. I have it. The wall switch 6 is a switch for turning on / off the power. In addition, the control unit 2
Is connected to a power source and a ceiling-embedded ventilation fan 3 through a wall switch 6.

面等にはまだ水滴が生じているが結露センサ１付近の空
気は乾燥している場合も、天井埋込換気扇３を一定時間
運転し、換気の目的を達成することとなる。In the above configuration, when the user turns on the power by the wall switch 6, the ceiling embedded ventilation fan 3 is operated or stopped for a certain period of time with the humidity lower than the reference humidity set by the setting switch 7 as a reference value. Therefore, for example, in the winter, when the power is not turned on immediately after leaving the bath and when the power is turned on several hours later, water drops are still generated on the wall surface and the like in the bathroom 4, but the air around the dew sensor 1 Even when it is dry, the ceiling-embedded ventilation fan 3 is operated for a certain period of time to achieve the purpose of ventilation.
なお、電源投入後、基準湿度から一定値近くしてそれ
を基準値としているが、この低減値は、換気を必要とす
る浴室内のとくに湿度の高い部分の湿度と、そのときの
結露センサ付近の湿度との相関性を実験的に求めて定め
ており、その値は10％程度が最適である。After turning on the power, the reference humidity is close to a certain value and used as the reference value.This reduced value is the humidity of a particularly humid part in the bathroom requiring ventilation and the vicinity of the condensation sensor at that time. Experimentally determined the correlation with the humidity of, and the optimum value is about 10%.

間経過後、天井埋込換気扇３は停止する。Then, after controlling for a fixed time at a low reference humidity, the reference humidity is changed to the reference humidity set by the setting switch to control the ceiling-embedded ventilation fan 3. When the dew condensation sensor 1 detects a humidity higher than the reference humidity, the ceiling embedded ventilation fan 3 is operated,
Then, when it is detected that the humidity in the bathroom 4 has dropped and becomes lower than the reference humidity, the operation shifts to the residual delay operation, and after a lapse of a certain time, the ceiling-embedded ventilation fan 3 stops.

達成されたという効果が得られる。EFFECTS OF THE INVENTION As is clear from the above description of the embodiment, according to the present invention, the bath temperature is controlled in the winter period by controlling the operation of the ventilation fan with the humidity which is lower than the reference humidity set in advance after turning on the power as a reference value. When the power is turned on a few hours later, if there are many water drops on the wall surface in the bathroom and ventilation is required, the ventilation fan is automatically operated even if the condensation sensor is dry. The effect that the purpose of ventilation is certainly achieved is obtained.
