Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-room ventilator for ventilating a plurality of rooms.

[0002]

2. Description of the Related Art Conventionally, a multi-chamber ventilation fan of this type is provided with a ventilator for ventilation in a main body and a plurality of suction ports on a side surface of the main body, so that air in a plurality of rooms such as a bathroom, a toilet, a toilet, etc. By ventilating, the humidity in the bathroom and toilet and the odor in the toilet are exhausted to the outside.

[0003] In addition, for the purpose of suppressing noise and reducing the air volume, a damper for electrically opening and closing the suction port is provided at the suction port.
Some air intake only from the room you want to ventilate.

[0004]

However, in the above-mentioned conventional configuration, the room to be ventilated and the air inlet for taking in air from the room are predetermined, so that the layout of the bathroom, toilet, and lavatory at the installation site is set. In some cases, there has been a problem that the duct length for piping is long, and the workability is poor because duct piping is difficult.

Further, when a duct from a room to be ventilated is erroneously connected to a different intake port, the piping has to be redone, which causes a problem that it takes much time and effort.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a multi-room ventilator having a simple duct pipe and excellent workability.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a multi-room ventilator that is installed on a ceiling of a bathroom and ventilates air in a plurality of rooms by operating a blower provided in a main body. A plurality of suction ports for sucking air in a plurality of rooms provided in the main body or a suction chamber connected to the main body, an intake duct communicating the suction port with the plurality of rooms, and a suction port provided in the suction port A damper that electrically opens and closes and a control unit that drives and controls the damper,
A selection means capable of selecting the suction port is provided so that the suction port can correspond to any of a plurality of rooms.

According to this configuration, since the suction port for connecting the intake duct can be arbitrarily selected according to the site, the construction is simplified, and the extra intake duct section can be eliminated, thereby reducing the cost. be able to. In addition, even if the air intake duct is accidentally connected to a different air inlet, after installing the main unit, it is possible to select the air inlet corresponding to the room you want to ventilate, making it easy for careless mistakes when piping the air intake duct Can be dealt with.

In addition, if the selection means is configured to select the suction port by attaching and detaching a relay connector connected to the drive unit of the damper, the suction means can be manufactured with a simple structure at a low cost, and the durability is higher than when a switch or the like is used. Is improved.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view showing an installation example of a multi-room ventilation device according to the present invention, and FIG. 2 is a perspective view showing a main part of the multi-room ventilation device.

As shown in FIGS. 1 and 2, a main body 1 installed on the ceiling of a bathroom A is provided with a blower 2 having a blower fan (not shown) inside the main body 1 and facing the inside of the bathroom A. A decorative plate 11, a first suction port 4 and a second suction port 6 provided on the side surface of the main body 1 to take in air from a plurality of rooms, and an exhaust port 31 for exhausting air sucked from the plurality of rooms to the outside. It is composed of

The suction ports 4 and 6 are provided with dampers 9 and 10 for opening and closing the suction ports 4 and 6, respectively, and a damper driving device 12 for electrically opening and closing the dampers 9 and 10 is provided. , 13 are provided.

Further, each of the damper driving devices 12 and 13 includes:
It is connected to the control unit 14 via a changeover switch 8 for switching the opening / closing command of each damper 9, 10.

As shown in FIG. 2, the first suction port 4 is connected to the suction duct 5 communicating with the suction port 17 for sucking the air in the toilet B, and the second suction port 6 is connected to the washroom. The intake duct 7 is connected to an intake port 19 for sucking the air in C.

Further, the air in the bathroom A, the air in the toilet B, the air in the toilet B, and the air in the toilet B sucked from the air inlet (not shown) provided in the decorative board 11 by the operation of the blower 2 are provided to the air outlet 31.
An exhaust duct 3 for exhausting the air inside to the outside is connected.

Therefore, the operation of the blower 2 in the main body 1 enables a ventilation operation in which the air in the bathroom A, the toilet B, and the toilet C is exhausted from the exhaust duct 3.

A remote control unit (hereinafter abbreviated as "remote control") for controlling on / off of ventilation operation of the bathroom A, the toilet B, and the washroom C is provided at an appropriate place outside the toilet B and in the washroom C. ) 41 and 43 are provided, and are connected to the control unit 14 by signal lines 45 and 47.

FIG. 3 is a plan view showing another installation example of the multi-room ventilator according to the present invention. The same components as those in the above-mentioned installation example are denoted by the same reference numerals, and the description thereof will be omitted.

In the case of this installation example, the toilet D and the toilet E
Is different from the above-described installation example in that the arrangement of the above is different.

That is, the first suction port 4 of the main body 1 is
The second suction port 6 of the main body 1 communicates with the suction port 27 provided facing the inside of the toilet D via the suction port 39 and the suction duct 7 provided facing the inside of the toilet D. Communicating.

In the appropriate places outside the toilet E and in the toilet D, the ventilation operation of the bathroom A, the toilet E and the toilet D is turned on.
Remote control units (hereinafter, abbreviated as “remote controller”) 43 and 41 for controlling turning off and the like are provided, and are connected to the control unit 14 by signal lines 47 and 45.

The operation will be described in detail based on the above configuration.

As shown in the time chart of FIG. 4, when the remote controller 41 provided at an appropriate place outside the toilet B is turned on, the blower 2 is activated, the damper 10 is closed, the damper 9 is opened, and the inside of the toilet B is opened. The air can be ventilated.

As shown in the time chart of FIG. 5, when the remote controller 43 provided in the washroom C is turned on, the blower 2 is operated, the damper 9 is closed, the damper 10 is opened, and the washroom C is opened. Ventilation inside can be performed.

Here, as shown in the time chart of FIG. 6, when the changeover switch 8 is switched to turn on the remote controller 41 provided in the toilet D, the blower 2 is operated, the damper 9 is closed, and the damper 10 is closed. Opens, and the air in the toilet D can be ventilated.
