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 ventilator main body 1 includes a first duct 102 that communicates the ventilator outlet with the room D, a second duct 103 that communicates the ventilator inlet with the room D, and a second duct 103 that communicates the outlet with the outdoor room C. A third duct 104 is connected to the room D.
and the outdoor 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 system 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. , and other air is exhausted to the outside C through the third duct 104. In addition, since the air is exhausted to the outside C, the inside of the room D becomes negative pressure, and the fourth duct 105
Air from outside C is supplied to room C through.

Problems to be Solved by the Invention This conventional configuration has the problem of being able to heat and ventilate only one room, 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 provides a ventilator main body having a blower and a damper at the blower outlet, and a ventilator main body having a damper at the blower outlet, and a ventilator main body having a damper and a first chamber connected to the ventilator main body. A first duct that communicates with the first room, a second duct that communicates the suction port of the ventilation device main body with the first room, and a third duct that communicates the discharge port of the ventilation device main body with the second room. a fourth duct that communicates between the outlet of the ventilator main body and the outdoors; and a fifth duct that communicates the first room and the outdoors; the discharge port and the third
A heater is provided at the second chamber discharge port of the duct, and air is switched between the first and second chambers using a damper.

Effect: With this configuration, the first room and the second room can be heated and ventilated with one ventilation device by opening and closing the damper provided at the blower outlet.

Embodiment An embodiment of the present invention will be described below based on FIG. In FIG. 1, reference numeral 1 denotes a main body of the ventilation system that includes a built-in blower 10, and its discharge port and the first chamber A are communicated with each other through a first duct 2. The room A is communicated with by a second duct 3. Furthermore, the outlet of the ventilation device main body 1 and the second room B are connected to the third duct 4.
The outlet of the ventilator main body 1 and the outside of the room are communicated by a fourth duct 5. The first room A and the outdoors are communicated through a fifth duct 6. A damper 7 is provided at the outlet of the blower 10 in the ventilation system 1, and a heater a8 and a heater b9 are provided at the outlet of the first duct 2 and the third duct 4, respectively.

In the above configuration, when heating the first room A, a changeover switch (not shown) opens the damper 7 in the direction A and energizes the heater a8. The air in the outdoor room C passes through the fifth duct 6, and the air in the first room A passes through the second duct 3, respectively.
Part of the air flowing into the ventilation system main body 1 is exhausted through the fourth duct 5, and the other air is heated by the heater a8 provided in the first duct 2 and sent to the first room A. It is discharged. Also, heater a
If only 8 is turned off, normal ventilation will occur.

Next, when heating the second room B, the damper 7 is opened in the direction B by a changeover switch (not shown), and the heater b9 is energized. Air from outside the room C passes through the fifth duct 6, and air from the first room A passes through the second duct 3, respectively, into the ventilation device main body 1, and then into the heater b9 provided in the third duct 4. It is then heated and discharged into the second chamber B.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, one ventilation device can ventilate one room and heat two rooms, and the equipment cost per room can be reduced. can get.
