Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system for air in a bathroom of a house.

[0002]

2. Description of the Related Art Conventionally, in the ventilation of bathrooms in general houses, it is common to operate / stop the ventilation fan by manual operation.
Depending on the user's feeling at that time, since the operation was not strictly related to the humidity in the bathroom, there was a problem that power wasted or power was consumed or mold was generated on the wall.

In order to solve such a drawback, for example, in Japanese Patent Laid-Open No. 58-15613, a dew sensor is used to detect the humidity in a bathroom, and when the detected humidity is higher than a set value, the bathroom is exposed. The proposal of the method of making the installed ventilation fan operate automatically is disclosed.

[0004]

However, the following problems can be considered with respect to the above-described ventilation device: 1) In the case of a ventilation system that only exhausts indoor air using a normal ventilation fan, exhaust air is discharged. The supplementary air supply is, for example, a natural air supply from a bathroom door, and generally the air supply and exhaust are not balanced and efficient ventilation is not performed.

2) In this case, if the exhaust capacity of the ventilation fan arranged in the bathroom is relatively large, the air supply may be drafts from the bathroom door and may directly hit the bather.
Especially in winter, there is a fear of feeling cold and causing discomfort.

3) The bathroom and the washroom which doubles as a dressing room are usually arranged adjacent to each other, and water vapor generated in the bathroom such as steam mixed with normal air passes through the washroom (dressing room). And propagate to other rooms. At this time, in the case of the conventional ventilator for the bathroom only, water vapor that cannot be discharged in the bathroom first moves to the washroom (dressing room), but since there is no ventilator in the washroom (dressing room), It may be propagated to other rooms.

The present invention has been made in view of the above problems, and can reliably ventilate both the bathroom and the washroom (dressing room) without causing discomfort to the bather. Another object is to provide a bathroom ventilation system in which water vapor and the like do not propagate to other rooms.

[0008]

Therefore, according to the present invention, the first means for detecting the state of air quality in the bathroom is provided.
Sensor means and a ventilation fan for exhausting indoor air, and a second air quality sensor means, an air supply port, and operation of the ventilation fan in the washroom (dressing room) adjacent to the bathroom. A second air supply is provided in the bathroom by configuring it to have adapter means for driving and controlling the opening and closing of the air supply port and operation switch means having these control operation state display means. It is intended to achieve the above object by arranging the mouth and the second ventilation fan in the wash room (dressing room).

[0009]

[Function] With the above-mentioned structure, the bathroom and washroom (dressing room) are reliably ventilated, there is no fear of giving discomfort to the bather, and it cannot be discharged by the conventional bathroom ventilation device. Water vapor and the like are prevented from propagating to another room.

[0010]

EXAMPLES The present invention will be described below based on examples. FIG. 1 is a schematic configuration diagram of an embodiment of a bathroom ventilation system according to the present invention, and FIG. 2 is a system configuration block diagram thereof. In FIG. 1, B and W respectively indicate an adjacent bathroom and washroom (also used as a changing room). On the ceiling of the bathroom,
The humidity sensor 1a and the temperature sensor 1b respectively shown in FIG.
The first in-bathroom sensor 1 having the above is arranged, and the ventilation fan 4 is arranged above the inner wall of the bathroom. On the other hand, an openable air supply port 5 is provided above the side wall surface of the washroom (dressing room) W opposite to the bathroom B, and a commercial power supply AC100V is provided on the ceiling.
Is supplied, and an adapter 2 for driving and controlling the operation of the ventilation fan 4 and the opening / closing operation of the air supply port 5 is arranged. Inside the adapter 2, each sensor 1a in the first sensor 1,
A second sensor 2A including the same sensors as 1b is provided. Further, on the side wall of the bathroom B, a remote control switch 3 using infrared rays or radio waves having a display panel 3a for displaying each operation state and a manual operation key 3b for each operation setting is provided. There is.

In the adapter 2 of FIG. 2, 6 is a multiplexer and A / D converter, 7 is a CPU, 8 is an interface, and 9 is a drive circuit for the ventilation fan 4 and the air supply port 5. With the above configuration, bathroom and washroom (dressing room)
Both are surely ventilated so that the bather does not feel uncomfortable and the water vapor is prevented from propagating to other rooms. Also, by using the remote control switch 3, it is possible to reduce wiring between the adapter 2 and
Of course, it does not matter even if a normal wired system is used.

(Other Embodiments) FIGS. 3 and 4 are views corresponding to FIGS. 1 and 2, respectively, of the other embodiments, and all the same (corresponding) components as those in FIGS. The same reference numerals are used, and the duplicated description of each is omitted. In this embodiment, as shown in FIGS. 3 and 4, a second air supply port 5A is provided on an upper portion of one wall surface in the bathroom B shown in FIGS. 1 and 2, and a second air inlet is provided on an upper portion of one wall surface of the washroom (dressing room) W. Two ventilation fans 4A are additionally provided, and the operation, control, display and the like of the adapter 2 and the remote control switch 3 are associated with each other, so that the effect of the above-described embodiment can be further ensured.

[0013]

As described above, according to the present invention, efficient ventilation is ensured both in the bathroom and the washroom (dressing room), and the bather does not feel uncomfortable and the other room There is no fear of water vapor or the like being transmitted.
