Description

  The present invention relates to a residential ventilation system configured to perform both odor exhaust in a miscellaneous drain pipe and ventilation in a house.

  No matter how tightly connected the equipment (kitchen, washstand, washing machine, etc.) connected to the miscellaneous drain pipe installed in a house, etc., if the equipment is equipped with a vinyl bellows pipe, etc. After that, there was a gap in the joint, and odor due to dirt inside the miscellaneous drainage pipe, water vapor, and the like sometimes leaked from there.

  Conventionally, a miscellaneous drain pipe is provided with a trap before it is connected to an outdoor public sewer, and a device connected to the miscellaneous drain pipe is also provided with a trap for measures against odor due to the contamination of the miscellaneous drain pipe over time. It was.

  In that case, the tighter the connection part of the instrument connected to the miscellaneous drainage pipe, the more it becomes a double trap, the problem of drainage becomes worse and the lower sealed water breaks, etc. did not become.

  When constructing a vent pipe, the construction cost is high, and the tip of the vent pipe released to the outside air enters the high pressure zone of the wind, or the room is negatively pressured using a range hood fan etc. There is a risk that the odor will flow into the room, especially when there is a looseness in the tight part of the appliance connected to the miscellaneous drainage pipe. .

  In addition, traps provided in each appliance connected to a miscellaneous drain pipe are likely to be clogged with firewood and oil in the kitchen, for example, baths, washstands and washing machines are likely to clog fibers and hair, etc. It was causing problems such as being broken due to tubule phenomenon. Furthermore, in highly airtight houses, the generation of odor due to the constant accumulation of water in the trap has become a problem.

  In recent years, ventilation of houses based on the Building Standards Law has been implemented. As an example of actual construction, there are overwhelmingly a lot of type 3 ventilation systems that perform exhaust mechanically and supply air naturally. Since the ventilation system uses negative pressure indoors, if the air supply path is not sufficiently secured by opening and closing the indoor door or the outside air introduction path, odor leakage from the joint of the miscellaneous drainage pipe may occur. The solution was urgent.

  FIG. 8 shows the flow of air in a general existing house. When the exhaust fans 3, 3... Appropriately installed in the rooms 2, 2. The air in each of the installed rooms 2, 2 ... is discharged to the outdoors, and accordingly, each of the rooms 2, 2 ... becomes negative pressure so that the ventilation ports 4, which are appropriately installed in the rooms 2, 2, ... 4... Air is supplied from the opened windows 5, 5... Of each room 2, 2... Or a door (not shown). (Not shown).

  However, if the air is not sufficiently supplied from the vents 4, 4,..., Windows, doors, gaps, etc., for example, the windows 5, 5, etc. are closed, and the exhaust fan is in a state where the rooms 2, 2,. When rotating 3, 3, ..., miscellaneous drainage devices 8, 8 ... such as kitchens, washstands, washing machines, etc. provided in the branch pipes 7, 7 ... of the miscellaneous drainage pipes 6 installed in the rooms 2, 2 ... Odors in the miscellaneous drainage pipe 6 and the branch pipes 7, 7... From the gap between the connection part (not shown), the gap between the bellows part (not shown), or the trap part (not shown) where the sealed water is broken. Intrusions into the rooms 2, 2 ... will contaminate the air in the rooms 2, 2 ....

  FIG. 9 shows the flow of air in a house in which a third type ventilation system stipulated in the Building Standards Law, that is, a ventilation system that mechanically exhausts air and supplies natural air, is shown. When the exhaust fan 10 that is an exhaust device installed in the exhaust pipe 9 communicating with each of the rooms 2, 2,... Rotates, the air in each of the rooms 2, 2,. 10 is discharged to the outside, and as a result, each of the rooms 2, 2... Becomes negative pressure so that the vents 4, 4. The air is supplied from the windows 5, 5... Or the doors, but is also supplied from various gaps between the rooms 2, 2.

  However, when the air is not sufficiently supplied from the vents 4, 4..., Windows 5, 5, doors, gaps, etc., for example, the windows 5, 5, doors are closed, and the rooms 2, 2. When the exhaust fan 10 is rotated, the connecting portion with the miscellaneous drainage devices 8, 8 ... provided in the branch pipes 7, 7 ... of the miscellaneous drainage pipe 6 installed in the rooms 2, 2 ..., the gap between the bellows portions, Or, the odor in the miscellaneous drainage pipe 6 and the branch pipes 7, 7... Enters the rooms 2, 2... From the trap part where the sealed water is broken, and contaminates the air in the rooms 2, 2. become.

Moreover, the exhaust apparatus of a house is also disclosed in, for example, Patent Documents 1 and 2, and Patent Document 1 discloses that the heat exhausted from the house that can quickly exhaust the hot air in the room during the summer night of a highly airtight house to the outside. Forcible exhaust system is described, and Patent Document 2 describes a ventilation system that enables effective outside air introduction by switching supply / exhaust paths by opening / closing an air supply / exhaust port and adjusting a fan air volume. Yes.
