Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ventilation system installed in a toilet, washroom, bathroom, etc.

BACKGROUND ART Conventionally, this type of ventilation apparatus has generally had a configuration as shown in FIG. 2, although no specific literature can be cited. That is, the ventilation device main body 101 has its discharge port and suction port communicated with the room D through a first duct 102 and a second duct 103, and
The outlet of this ventilation device main body 101 and the outdoor C are the third
The room D and the outdoor room C are communicated through a fourth duct 105. Further, a heater 109 is provided at the outlet of the blower.

In the above configuration, the air in the room D is sucked into the ventilation device main body 101 through the second duct 103, and some of the air is heated by the heater 109 and circulated into the room D through the first duct 102.
Other air is exhausted to the outside C through the third duct 104. Further, since the air is exhausted to the outside C, the inside of the room D becomes a negative pressure, and the air from the outside C is supplied to the room C through the fourth duct 105.

Problems to be Solved by the Invention With such a conventional configuration, there was a problem in that only one room could be heated and ventilated, resulting in relatively high equipment costs per room. The present invention takes these problems into consideration and aims to provide a ventilation device that can heat and ventilate two rooms with one device.

Means for Solving the Problem In order to solve this problem, the present invention includes a ventilation device main body having a blower consisting of one motor and two blades, and heaters at two outlet ports, A first duct that communicates between one outlet of the ventilation device main body and the first room; a second duct that communicates the suction port of the ventilation device main body with the first room; A third duct that communicates between the discharge port and the second room, a fourth duct that communicates between the first room and the outdoors, and a fifth duct that communicates between the suction port of the ventilation device main body and the outdoors. It has the following.

Effect: With this configuration, it is possible to simultaneously heat and ventilate the first room and the second room with one ventilation device.

Embodiment An embodiment of the present invention will be described below based on FIG.

In Fig. 1, 1 is a motor 9 and two blades 7,
8, and communicates with the first chamber A of its discharge port and suction port through a first duct 2 and a second duct 3. Further, the outlet of the ventilator main body 1 and the second room B are communicated with each other by a third duct 4, and the outlet of the ventilator main body 1 and the second room B are communicated with each other through the third duct 4,
A fourth duct 5 communicates with the ventilator main body 1, and a fifth duct 6 communicates between the suction port of the ventilation device main body 1 and the outdoor room C. The discharge air discharged through one blade 7 in the ventilation device main body 1 is guided to the third duct 4, and the other blade 8
The discharge air discharged through the first duct 2 is guided to the first duct 2, and heaters 13 and 11 are provided at the entrances of the ducts 4 and 2, respectively.

In the above configuration, when the motor 9 is rotated, the fifth
Outdoor air is taken in through the second duct 6, air inside the room A is taken in through the second duct 3, and the blades 8
The air is blown into the room A through the first duct 2, and a part of the air taken in from the fifth duct 6 is blown into the room B through the third duct 4 through the blades 7. be done. Here, room A is the second
The indoor air taken in through the duct 3 and the outdoor air taken in through the fifth duct 6 become pressurized because they are taken in through the first duct 2, and a part of the air taken into room A is transferred to the fourth duct 6. 5 and is discharged outside the room. Further, when blowing warm air to rooms A and B, the heaters 11 and 12 are energized to heat the air passing through.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, a ventilator main body having two blades driven by one motor is used, and a heater is provided at its two discharge ports. Since each of the two rooms is connected by a duct, one ventilation system can ventilate and heat two rooms, which has the effect of reducing equipment costs per room.
