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 something.

BACKGROUND OF THE INVENTION Conventionally, this type of ventilator has been generally constructed as shown in FIGS. 2 and 3, although there are seven specific documents. The ventilator main body 101 shown in FIG. 2 has a blower 103 and a sheathed heater 104 on its discharge side, and has a suction port 102 communicating with the room, and a first discharge port 106 on the discharge side of the blower 103 through a duct. A second outlet 106 on the blower outlet side is communicated with the room. The room C is provided with an air supply port 107 that communicates with the outdoors E, and the room C is provided with a ventilation blower 108, whose discharge port 108 is communicated with the outdoors E via a duct.

In the above configuration, the air in the room is sucked into the ventilation device main body 101 by the blower 1o3 through the suction port 102, and a part of the air is heated by the sheathed heater 104, and the second
The other air is circulated into the room through the first outlet 106, and other air is exhausted outside the room through the first outlet 106. Also, some of the air taken in is exhausted to the outdoor E3 hedge through the first discharge port 105, so the inside of the room becomes negative pressure, and the air supply port 105 becomes a negative pressure.
Air from outside E is supplied to the room through 7. The air in the room C is supplied by the blower 108 regardless of the ventilation system 1o1.
As a result, the air is exhausted to the outside E through the discharge port 109.

Ventilator body 110 of another conventional ventilator shown in Figure M3
has a blower 120 and a sheathed heater 119, has a first outlet 112 communicating with room F via a first duct 111, and communicates a second outlet 114 with room G via a second duct 113. The first suction port 116 is connected to the room G via the third duct 115, and the second suction port 118 is connected to the room G via the third duct 115.
is communicated with the outdoor H via a fourth duct 117.

The first duct 111 is equipped with an electric damper AI 21.
An electric damper B122 is provided in the second duct 113, and the room G and the outdoor H are communicated through an exhaust port 123.

In the above configuration, when drying and heating room G,
Electric damper A121 is closed and electric damper B122 is opened. In this state, the air in room G is
15, the air from outside H is transferred to the fourth duct 117.
The air is sucked into the ventilation device main body 110 through the ventilator body 110, heated by the sheathed heater 119, and discharged into the room G through the second duct 113. Since the air is being supplied from the outside H, the pressure inside the room G becomes ■, and the air in the room G is exhausted to the outside H through the exhaust port 123. To dry or heat room F, open electric damper A121 and close electric damper B122 to dry or heat room F.

Ventilation and air blowing can be achieved by operating the blower 120 without turning on the power to the sheathed heater 119.

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

(1) If the blower malfunctions and no longer blows air, the sheathed heater will not be cooled down, and the heat of the sheathed heater may cause a fire.

(2) In Article J2 (]), when only the sheathed heater is energized, safety devices such as temperature fuses and thermostats must be installed in the ventilation system to prevent fires caused by the heat generated by the vanes. .

(3) The suction resistance of the blower changes depending on the length of the duct connected to the ventilation system and the piping method, and the discharge air volume changes accordingly, but the amount of heat generated by the sheathed heater remains the same.
Depending on the piping method, the discharge temperature of the ventilator body may not be constant.

The present invention solves these problems, and aims to provide a ventilation system in which the amount of heat generated per discharge air is always constant.

Means for Solving the Problem In order to solve this problem, the present invention provides a ventilator that is installed inside the main body of the ventilation device, which is installed on the ceiling in contact with the boundary between the first room and the second room. A blower having a no-nikum heater is provided in the discharge portion, and the blower discharge side has a first discharge port discharging the discharge into the first chamber, a second discharge port discharging the discharge into the second chamber, and a first discharge port discharging the discharge into the second chamber. The blower has a damper that selects air blowing to either one of an outlet and a second discharge port, and the blower suction side has a first suction port that draws air from the first part 66, and a damper that draws air from the first part 66 to the outside through a duct. The ventilator is provided with a second suction port communicating with the ventilator.

Function: In this configuration, the damper selects air flow to either the first room or the second room to dry, heat, ventilate, or blow air to either the first room or the second room. When the honeycomb heater is energized, the amount of heat generated per unit discharge air volume is always constant.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIG. In Fig. 1, reference numeral 1 denotes a ventilation system main body that is installed on the ceiling in contact with the boundary wall between bathroom A and washroom B and has a built-in blower 2, and the blower outlet side and bathroom A are communicated through a first outlet 3. The blower discharge side and the washroom B are communicated with each other through the second outlet 4, the blower suction side and the bathroom A are communicated with each other through the first suction port 6, and the blower suction side is connected with the bathroom A through the second suction port 6. 6 and the outdoor I are communicated via a duct.

Page 7 A heater 7 is disposed at the outlet of the blower 2, and the first outlet 3 and the second outlet 4 are switched by a damper 8. "Select the air blower to one of the following":

Note that the bathroom A and the outdoor area are communicated through an exhaust port 9.

In the above configuration, when drying the bathroom A, the damper 8 closes the second discharge port by using a changeover switch (not shown),
The Noronicum heater 7 and the blower 2 are energized. In this state, air is sucked into the blower 2 from the bathroom A and the outdoor area, heated by the heater 7, and discharged into the bathroom A through the first outlet 3. can be used as a drying room. Here, some air is supplied to the bathroom A from the outside (2), and the pressure inside the bathroom A becomes (2), so a part of the air discharged from the bathroom A is discharged to the outdoor area through the exhaust port 9. In addition, when taking a bath in the bathroom, the heated air can be used as preliminary heating before taking a bath in winter.

1. By operating the blower 2 without turning on the power to the honeycomb heater 7, it can be used for ventilation, and in summer, it can be used as a blower instead of a fan.

Next, when heating the washroom B, use the damper 8 to
The discharge port 3 is closed and the honeycomb heater 7 and blower 2 are energized. In this state, air from the bathroom A and outside ■ is sucked into the blower 2, heated by the honeycomb heater 7, and
The heated air is discharged into the washroom B through the discharge ITJ4, and the washroom B can be heated by this heated air.

In addition, the amount of heat generated by the honeycomb heater 7 is proportional to the discharge air flow in response to changes in the discharge air flow due to the length of the duct connected to the ventilation device body 1, the suction resistance of the blower 2 due to the piping method, and the discharge resistance. According to the present invention, the amount of heat generated per discharged air H1 is always constant.As is clear from the explanatory power of the embodiment described in 1. So 2
When a room can be ventilated, dried, heated, and blown by heating and air is heated by a honeycomb heater, the amount of heat per amount of air discharged is always constant at the level of j149 Beno, and the amount of discharged air h1:
When becomes 0, the Nicum heater does not generate heat, and even if the blower breaks down, there is no risk of fire.
