Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bathroom ventilation control device that automatically operates ventilation devices such as bathroom ventilation fans and electric window opening/closing devices.

(Prior Art) In bathrooms, it is important to prevent the generation of mold through ventilation, and conventionally, windows have been opened and closed manually and ventilation fans have been started.

[Problem to be solved by the invention]

However, manually performing ventilation is inconvenient, and ventilation is often forgotten.

Although it is possible to perform ventilation at a predetermined time every day using a timer or the like, the frequency of use of the bathroom varies depending on the day, and sufficient ventilation may not be performed or ventilation may be performed unnecessarily.

Another idea was to automatically ventilate the bathroom after each use, but if another person takes a bath in succession without leaving the bathroom open for too long, the temperature in the bathroom would drop due to ventilation.
The problem is that it gets cold.

An object of the present invention is to provide a bathroom ventilation control device that can perform the necessary amount of ventilation depending on the use of the bathroom, and can prevent the inside of the bathroom from becoming cold due to ventilation when the bathroom is subsequently used. be.

[Means to solve the problem]

The bathroom ventilation control device of the present invention includes first timer means for activating the bathroom ventilation device after a first set time has elapsed from the time when the on/off switch of the electrical equipment used when bathing in the bathroom is turned off. establish.

Means is provided for resetting the first timer means in response to the ON operation of the opening/closing switch. Further, a second timer means is provided for disabling the ventilator after the set time period 2 after activation of the ventilator has elapsed. The electrical equipment includes bathroom lighting equipment, electric curtains, etc.

[action] According to the configuration of this invention, it operates as follows.

Normally, when using the bathroom, electrical equipment such as lighting fixtures in the bathroom are used, and when leaving the bathroom, the on/off switch of the electrical equipment is turned off, and this off operation is used to activate the ventilation system. That is, when the first set time elapses,
The first timer means activates the ventilation device. For example, when the ventilation device is a ventilation fan, the ventilation fan is activated. If the ventilation system is an electric window opening/closing device, make the window open.

Thereafter, the second timer means disables the ventilator when a second set time has elapsed.

In this way, the ventilation system is automatically operated by operating the on/off switch when using the bathroom. If the bathroom is used again before the first set time elapses after leaving the bathroom, the opening/closing switch is turned on, and this turning on operation resets the first timer means and activates the ventilation system. I won't let you. This prevents the next person taking a bath from experiencing discomfort such as coldness due to the ventilation of the bathroom.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 to 3. The bathroom 1 is equipped with electrical equipment 2 and a ventilation system 3 used during bathing. The electrical equipment 2 is, for example, a bathroom lighting fixture, an air-conditioning device, a sound device that plays music, an electric curtain, an electric blindfold, or the like. The ventilation device 3 is a ventilation fan, an electric window opening/closing device, or the like.

The electrical equipment 2 is activated by turning on the on/off switch SW, and stopped by turning it off. Reference numeral 4 denotes a control circuit for controlling the ventilation device 3, which includes a first timer means T, a second timer means T, and a reset means 6. The first timer means T, starts from the time when the open/close switch SW1 is turned off.
