Then, the suction port 116 provided in each room and the indoor side suction port 101 are communicated with each other by the return air duct 115, and the discharge port 118 and the indoor side discharge port 102 provided in each room are communicated with each other by the air supply duct 117. Was there.
In the figure, reference numeral 119 is a range hood provided in the kitchen 120, and the air in the kitchen 120 is exhausted to the outside during cooking.

In such a configuration, the motor 109 and the ventilation motor 113
When the air conditioner is driven, the indoor air is drawn in through the suction port 11 as indicated by arrow u →.
6. The air is drawn into the main body 100 through the return air duct 115, and a part of it is passed through the heat exchanger 114 by the exhaust blades 111 and the arrow V →
Like the outside air that is exhausted to the outside as shown by the arrow and is mostly sucked by the circulation blades 108, and is sucked from the outside by the air supply blades 112 as shown by an arrow W ... → through the heat exchange air 114 and is sucked in. Then, it was heated or cooled by the heat exchange coil 110, and was discharged from the discharge port 118 provided in each room through the air supply duct 117 as shown by the arrow X →.
In addition, when the range hood 119 provided in the kitchen 120 is operated in this state, the steam and oil smoke generated in the kitchen 120 are discharged outside by the range hood 119.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional configuration, a part of the odor sucked from the toilet and the humid air sucked from the washroom can be discharged to the outside by the exhaust blades 111, but most of them are discharged from other rooms. It is heated or cooled by the heat exchange coil 110 together with the inhaled indoor air and discharged to each room again, and the odor of the toilet is diffused throughout the building, which is unfavorable for hygiene, impairs comfort, and humid air. Due to insufficient discharge of water, there was a risk of condensation on the north wall of the building. When the range hood 119 provided in the kitchen for discharging steam and oil fumes generated during cooking is driven, the inside of the room becomes negative pressure, and the outside air enters the room as a draft and cools,
Or the heating effect was significantly reduced. Moreover, since the amount of air supplied from the outside is small, the effect of discharging steam and oil smoke from the range hood 119 was poor.

The present invention is to solve the above-mentioned conventional problems, enabling heat exchange ventilation and heating, or cooling of each room, and exhausting all the odors of the toilet and the humid air of the toilet, the odor of the toilet and the toilet. The humidity of the room is prevented from diffusing to each room, and when the range hood is operated, the outdoor air is forcibly supplied and heated or cooled before it is supplied to each room to prevent the room from becoming negative pressure. And air conditioning,
Another object of the present invention is to provide a ventilation air conditioner that prevents a reduction in heating effect and enhances the effect of discharging steam and oil smoke from a range hood.

Means for Solving the Problem In order to solve this problem, the present invention defines a circulation passage extending from an indoor suction port to an indoor installation port and a ventilation passage extending from a ventilation air supply port to an indoor discharge port. An air conditioning unit provided with a circulation vane and a motor in the circulation passage, and a heat exchange coil for heating and cooling the circulation air and the supply air at the confluence of the circulation passage and the ventilation passage; An exhaust passage extending from the mouth to the outdoor discharge port and an air supply passage extending from the outdoor suction port to the air supply port are formed to be compartments, and exhaust blades for blowing air to the exhaust passage, and air supply for blowing air to the air supply passage Blades,

And a duct for communicating with the range hood and a damper for selectively opening and closing the indoor side intake port and the outside air supply port in conjunction with the operation of the range hood.

With this configuration, when the range hood is stopped, the air in each room is sucked into the air conditioning unit through the duct from the suction port, and after being heated or cooled by the heat exchange coil,
The air is sucked from the outdoor suction port of the ventilation unit by the air supply blades, passes through the heat exchanger, merges with the outdoor air heated or cooled by the heat exchange coil, and is discharged to each room through the duct. In addition, the air in the toilet or washroom is sucked into the ventilation unit from the exhaust suction port through the duct, and is exhausted to the outside through the heat exchanger by the exhaust vanes. Alternatively, cooling is possible, and the air in the toilet or washroom is exhausted to the outside without transferring to another room. When the range hood is operated, the outdoor air is directly sucked into the circulation vanes by switching the damper, heated or cooled by the heat exchange coil and supplied to each room, and the air in the toilet or washroom is exhausted to the outside by the ventilation unit. It will be discharged and the range hood will prevent negative pressure in the room, prevent the cooling or heating effect from decreasing, increase the effect of steam and oil smoke discharge by the range hood, and also the air in the toilet or washroom. Will be discharged outside the room without moving to another room.
