Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ventilation device that is attached to the ceiling of a bathroom, washroom, or toilet and performs ventilation, drying, heating, ventilation, etc. of the bathroom, washroom, or toilet. It is.

BACKGROUND TECHNOLOGY Conventionally, this type of ventilator has generally had a configuration as shown in FIG. 2, although no specific literature can be cited. That is, the main body of the ventilation device has a blower 103 and a heater 104, sucks air from the room D through the suction port 102, heats some of the air with the heater 104, and releases it as heated air through the discharge port 106.
The air is discharged into the room D, and is also exhausted from the discharge side of the blower 103 to the outside E through a duct. It is becoming more and more common. Note that 107 in the figure is an air supply port that communicates the room D and the outside E.

Problems to be Solved by the Invention This conventional configuration has the following drawbacks.

(1) Since one equipment is required for each room, equipment costs are relatively high, and each room requires space to install the equipment.

(2) Each piece of equipment requires duct piping;
Construction costs are high and duct space is also required.

The present invention has been developed in consideration of these problems, and is capable of drying, heating, blowing air, and blowing air in two rooms with one device at low equipment cost.
The purpose is to provide a ventilation device that can perform ventilation.

Means for Solving the Problem In order to solve this problem, the present invention provides a blower with a heater inside a ventilation device main body provided on the ceiling surface, and the inside of the ventilation device main body is located on the blower discharge side. and a blower suction side, and the blower discharge side has a first outlet communicating with a first chamber, a second outlet communicating with a second chamber via a duct, and a second outlet communicating with the outside. and three discharge ports, and the air discharged from the blower is divided into a first and second discharge port and a third discharge port, and air is blown to the first discharge port and the second discharge port. A damper to be selected is provided, and a suction port communicating with the first chamber is provided on the suction side of the blower.

Operation In this configuration, one ventilation device can dry either the first room or the second room by selecting the damper to blow air to either the first room or the second room. , heating, ventilation, and blowing.

Embodiment Hereinafter, an embodiment of the present invention will be explained based on FIG. In FIG. 1, reference numeral 1 denotes a main body of the ventilation system, and a partition plate 2 is provided inside, a blower 3 is attached to the partition plate 2, and the partition plate 2 partitions the blower discharge side and the blower suction side.
The suction side of the ventilation device main body 1 has a suction port 6, and the blower discharge side has a first discharge port 4, a second discharge port 5, and a third discharge port 7. 4 is connected to bathroom A. The second outlet 5 communicates with the washroom B via a duct, and the third outlet 7 communicates with the outside I via a duct. A heater 8 is disposed at the outlet of the blower 3, and partition plates 11 are provided at the first outlet 4, the second outlet 5, and the third outlet 7 to control the outlet of the blower 3. The wind is distributed in two parts. Moreover, the first discharge port 4 and the second discharge port 5 are adapted to be selected for blowing air by a damper 9. Note that 10 in the figure is an air supply port that communicates the bathroom A and the outdoor room I. When drying the bathroom A in the above configuration, a changeover switch (not shown) is operated to close the second discharge port 5 with the damper 9 and energize the heater 8 and the blower 3.
In this state, the air in the bathroom A is sucked into the blower 3 through the suction port 6, heated by the heater 8, and discharged into the bathroom A through the first discharge port 4. The heated air dries the inside of the bathroom A. It can be used as a room. Here, bathroom A has outdoor I.
A further portion of the air is supplied through the air supply port 10, and a portion of the humid air is exhausted through the third discharge port 7.

The heated air can also be used for preliminary heating before taking a bath in winter. Furthermore, by operating the blower 3 without turning on the power to the heater 8, it can be used for ventilation, or as a blower in place of a fan in the summer.

Next, when heating the washroom B, the damper 9 closes the first discharge port 4 and the heater 8 and the blower 3 are energized. In this state, the air in the bathroom A is sucked into the blower 3, heated by the heater 8, and then
The heated air is discharged into the washroom B through the outlet 5, and the washroom B can be heated by this heated air.

Note that by operating the blower 3 without turning on the power to the heater 8, it can be used to blow air in place of an electric fan in the summer.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, one ventilation device can ventilate, dry, heat, and blow air into two rooms by switching dampers, and the equipment cost per room can be reduced. This has the effect of reducing duct construction costs, etc.
