Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation device, and more particularly to a room air ventilation device for a house.

[0002]

2. Description of the Related Art In recent years, the airtightness of houses has been improved with the progress of construction methods and materials for houses, which contributes to the improvement of livability, but on the other hand, polluted air is easily accumulated in the room. Ventilation must be done before contaminated air reaches acceptable limits. For this reason, there is a method in which contamination of indoor air is detected by a gas sensor, and when a preset allowable value is reached, the ventilation fan is automatically operated to discharge the air to the outside.

However, in such a device, a predetermined amount of polluted air is automatically discharged, but since there is no means for notifying the fact of this pollutant, a large amount of pollutants was generated beyond the exhaust fan's discharge capacity. Occasionally, the permissible value is greatly exceeded and it is dangerous for health and safety. Therefore, in order to prevent this, for example, in Japanese Unexamined Patent Publication No. 1-181026, a ventilation fan is automatically operated when the degree of pollution reaches a predetermined value by a sensor for detecting dirt in the room air, and an indoor alarm is issued by an alarm device. A method of notifying air pollution by a transmitter or the like has been proposed and disclosed. FIG. 7 shows a schematic diagram of the system. 21 is a ventilation device, 22 is a ventilation fan, 23 is each sensor,
Reference numeral 24 is an alarm device, and 25 is a control device.

[0004]

However, in the ventilation system as described above, when contaminated indoor air is ventilated, it is only exhausted from the exhaust port provided in the vicinity of the ventilation fan 22. , The supply of fresh air instead of this is, for example, a natural air supply from a gap in the door of the room or the air supply port provided at a predetermined place, and generally a good air supply / exhaust balance cannot be obtained, which is an effect. Often there is no effective ventilation.

That is, not only is the ability of the exhaust fan 22 for exhausting air not fully utilized and the ventilation efficiency is poor, but also the exhaust fan 22.
It also increases the driving noise of the vehicle and makes the user feel uncomfortable in the living room environment. Further, for example, when it is desired to ventilate for a reason other than air pollution that can be detected by the predetermined sensor 23, such as hot air in summer and a special odor, the ventilation fan cannot be operated alone as it is.

The present invention has been made in view of the above circumstances, and in a ventilator of this kind for automatically ventilating polluted air, not only a simple operation of a ventilation fan but also supply of air By performing control, it is possible to balance the air supply and exhaust so that efficient ventilation is performed, and
It is an object of the present invention to provide not only these automatic operation modes, but also ventilation that can be performed by manual operation if necessary, and that the automatic operation mode can be stopped when there is no particular need.

[0007]

Therefore, according to the present invention, a ventilation device of this type is provided with a sensor means for detecting the state of the air quality of a predetermined part of the room, and a ventilation fan means for exhausting the room air. This indoor air intake port, adapter means for driving and controlling the operation of the ventilation fan and opening / closing of the intake port, and operation switch means having these control operation state display means are provided, and the sensor means or operation switch is also provided. Means for automatically or manually controlling the operating state by means of each means, or further by using a wireless remote control system for the signal transmitting means for controlling the operating state. To do.

[0008]

With the above ventilation device configuration, automatic ventilation by the sensor means can be efficiently performed, and a single manual operation can be performed if necessary. In addition, the wiring of the system can be reduced by using a wireless remote control for exchanging control signals for the ventilation fan and the air supply port.

The present invention will be described below based on three embodiments. 1 and 2 are a schematic diagram of a ceiling adapter type system according to a first embodiment and its configuration block diagram, and FIGS. 3 and 4 are diagrams corresponding to FIGS. 1 and 2 of a wall switch type second embodiment. 5 and 6 are views corresponding to FIGS. 1 and 2 of the same as the third embodiment of the device-embedded type.

(First Embodiment) In FIG. 1, W indicates a wall of a room to be ventilated, and C indicates a ceiling. Reference numeral 1 is a first sensor portion arranged at a predetermined portion of the ceiling C that is optimal for accurately detecting the quality (contamination state) of indoor air. As shown in FIG. 2, the miscellaneous gas sensor 1a and the oxygen sensor 1b are provided. And CO ₂ sensor 1c
Including etc. Further, these sensors may include a carbon monoxide sensor, a propane sensor, a smoke sensor, etc. depending on the situation. Reference numeral 2 denotes an adapter for driving and controlling the operation of the indoor air exhaust ventilation fan 4 and the opening / closing operation of the air supply port 5 when a commercial AC 100V power supply is supplied, and inside thereof, each sensor 1a in the first sensor unit 1 is provided. , 1b,
A second sensor unit 2A including the same sensors as 1c is arranged.

Is configured to be. Reference numeral 3 is a remote control switch with an operation state display panel arranged on the wall W surface, the display panel 3a displays the automatic operation mode / state, etc., and a manual key switch 3b is used to select a mode other than this automatic operation mode. The user can optionally independently operate / operate the exhaust ventilation fan 4 and the air supply port 5 at any time. The remote control switch 3 and each sensor 1 are connected to the adapter 2 by an electric wire for receiving a power supply for driving the circuit, and the operation selected signal, the operation display signal, and the detection state signal of the sensor 1 are superimposed on the electric wire.
