Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure in a residential building.

[0002]

2. Description of the Related Art Conventionally, as a ventilation structure in a residential building, natural ventilation, mechanical ventilation, heat exchange mechanical ventilation, and the like have been known.

[0003] Of these, natural ventilation
Known are those due to leakage of the building itself or the opening, those with a ventilation frame on the sash, and those with a ventilation hole on the wall.

As the mechanical ventilation, there are known a wall ventilation fan type, a ceiling duct ventilation fan type, a central duct type, and the like.

Further, sensible heat exchange type and total heat exchange type are known as heat exchange mechanical ventilation.

[0006]

However, among the above-mentioned conventional ventilation structures, those using natural ventilation have the following disadvantages.

[0007] That is, in the case of leakage of the building itself or leakage of the sash, heat loss is large, and when the wind blows, cold drafts enter the room and heating becomes ineffective. Also,
Leaving ventilation only for leaks results in poor ventilation in tightly sealed houses.

[0008] Also, a type in which a ventilation frame is attached to the sash,
In the case of a type with ventilation holes on the wall, cold air enters in winter and gets cold, so these ventilation frames and ventilation holes are closed,
Inconvenience such as not using too much for ventilation occurs. In addition, when these ventilation frames and vents are opened, there is a disadvantage that sound leakage is large. Furthermore, recently residential buildings are highly airtight, so simply providing ventilation frames and vents does not allow air to escape, so there is no sufficient ventilation and there is a small difference in indoor and outdoor temperatures. Causes inconvenience such as insufficient ventilation.

[0009] In the case of mechanical ventilation, the following inconvenience occurs.

[0010] That is, in the case of the wall ventilation fan type, external sounds and drafts easily penetrate, and the appearance design of the building deteriorates. In the case of the ceiling duct ventilation fan type, the construction cost is high and the reliability of the function maintenance is low. Further, even if mold or dust accumulates in the duct, it cannot be cleaned, requiring a specialized company, and the price of the equipment is high. Further, in the case of the central dartok type, there is an inconvenience that maintenance is difficult.

[0011] Furthermore, in the case of the heat exchange mechanical ventilation, it is expensive and the heat exchange element is easily clogged. Further, in the case of the total heat exchange type, the contaminated gas easily flows backward, which is not suitable for ventilation.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ventilation structure for a residential building capable of performing efficient ventilation with low cost and low maintenance.

[0013]

In order to solve the above-mentioned problems, a ventilation structure for a residential building according to the present invention comprises a ventilation box having an air outlet formed on a ceiling surface of the residential building from the ceiling surface toward a room. In addition, a heat storage ventilation duct extends from a ventilation opening formed in the ventilation box to a ventilation gallery provided on the side wall of the house. Further, a pipe fan is provided at the ventilation port.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 schematically shows the overall structure of a ventilation structure of a residential building 1.

That is, this ventilation structure is configured by connecting the heat storage ventilation duct 4 between the ventilation box 2 and the ventilation gallery 3.

The ventilation box 2 is formed in a box shape with one surface opened, and one surface thereof serves as an air outlet 20. The ventilation box 2 is incorporated in an opening 12 provided in a ceiling surface 11 of the residential building 1, and is attached to the ceiling surface 11 so that the outlet 20 is located. The air outlet 20 is provided with a removable air outlet cover 21 formed in a lattice or mesh shape. The outlet cover 21 has an air filter (not shown) for preventing pollen and dust from entering the room 13.
It may be a device provided with such as. A pipe-shaped ventilation port 22 is provided in the ventilation box 2, and a power outlet 23 of a power plug 51 of the pipe fan 5 is provided in case the pipe fan 5 is attached to the ventilation port 22. Have been. The shape of the ventilation box 2 is not particularly limited because the ventilation box 2 is for taking outside air from the ventilation gallery 3 and the heat storage ventilation duct 4 into the room 13. Therefore, it is possible to use the ventilation box 2 which is freely designed in accordance with the design and space of the ceiling surface 11 of the room 13. However, in consideration of the installation of the pipe fan 5 and the cleaning of the heat storage ventilation duct 4 from the ventilation opening 22, it is preferable to use a ventilation opening 22 that is elongated in the axial direction.

The ventilation gallery 3 is located above the ceiling 14 of the residential building 1.
Is provided on the outer wall 15 so as to communicate with.

The heat storage ventilation duct 4 is connected to the ventilation box 2
Is connected so as to connect between the ventilation port 22 and the ventilation gallery 3. The heat storage ventilation duct 4 is not particularly limited, and various pipes made of resin, metal, or the like can be used. Further, a heat insulating material (not shown) may be coated on the outer peripheral surface to improve the heat storage property.

The ventilation structure of the residential building 1 constructed as described above can be easily constructed when the residential building 1 is constructed, and can be used as a natural ventilation device. For example, when the inside of the residential building 1 is heated in winter, when wind blows outside the residential building 1, the wind is taken in from the ventilation gallery 3 and passes through the heat storage ventilation duct 4, so that when the wind passes through the heat storage ventilation duct 4, the roof 14. After being heated to the ambient temperature, the air flows into the ventilation box 2, and is blown into the room 13 from the ceiling surface 11 provided with the ventilation box 2. Therefore, ventilation galleries 3
You don't feel the cold as if you were taking in fresh air directly from When the air is exhausted from the room 13, the air is exhausted from the ventilation gallery 3 through the heat storage ventilation duct 4 from the ventilation box 2. At this time, the air exhausted from the room 13 is heated by the indoor heating. Therefore, when passing through the heat storage ventilation duct 4, heat is released to the heat storage ventilation duct 4, and the heat storage ventilation duct 4 is heated and then exhausted. The heat stored in the heat storage ventilation duct 4 is
It is used to warm up this fresh air when it is later taken in. The same can be said for the case where cooling is performed in the residential building 1 in summer.

As described above, according to the ventilation structure, the heat in the room 13 can be efficiently ventilated without wasting heat. Further, this ventilation structure is arranged on the ceiling back 14, and has a ventilation gallery 3 and a heat storage ventilation duct 4.
The structure allows the outside air to be taken in from the ventilation box 2 to the room 13 through the air conditioner.

This ventilating structure may be constructed at one place per room. However, since recent residential buildings 1 have improved airtightness, the construction described above is performed at one place. When used as such a natural ventilation device, sufficient natural ventilation ability by wind power cannot be expected. Therefore, in such a case, it is preferable to use the pipe fan 5 as a mechanical ventilation device. To install the pipe fan 5, simply insert the pipe fan 5 into the ventilation port 22 and insert the power plug 51 of the pipe fan 5 into the power outlet 23 in the ventilation box 2, thereby calling a specialist. It can be easily installed without any.

Further, as shown in FIG. 2, this ventilation structure may be constructed at two places per room. In this case, when outside air is taken into the room from one ventilation box 2, the indoor pressure increases and the other ventilation box 2
Since the air is naturally exhausted from the air, it can function sufficiently as a natural ventilation device. However, in this case, it is desirable that the ventilation gallery 3 for taking in and exhausting outside air be provided at a position facing the residential building 1. That is, by providing in such a position opposed to each other, when outside air is taken in from the windward ventilation gallery 3, exhaust is performed from the leeward ventilation gallery 3, and smooth natural ventilation can be performed. . In this case, as shown in FIG.
May be provided adjacent to each other, or may be provided at a position away from the room 13. If installed adjacently, ventilation box 2
Can be installed all at once and installation can be simplified. In addition, when provided at a remote position, the outside air taken in from one ventilation box 2 is
After sufficient circulation in the room 13, the other ventilation box 2
Exhaust can be performed, and the ventilation efficiency can be improved.

Further, even when the ventilation structure is constructed at two places per room, the pipe fan 5 may be attached to one or both ventilation boxes 2 to be used as a mechanical ventilation device. . Thus, even when the pipe fan 5 is attached to form a mechanical ventilation device, since air flows through a gap between the pipe fans 5, a function as a natural ventilation device can also be achieved.

Further, in the case of this ventilation structure, maintenance can be easily performed by removing the outlet cover 21 and cleaning the inside of the heat storage ventilation duct 4 with a vacuum cleaner or a brush with a wire. In addition, even when the pipe fan 5 is attached, the power plug 51 of the pipe fan 5 can be pulled out from the power outlet 23 and the pipe fan 5 can be easily pulled out from the ventilation port 22 for easy maintenance. It can be carried out.

[0026]

As described above, according to the present invention, the air taken from the ventilation gallery is heated to the ambient temperature above the ceiling when passing through the heat storage ventilation duct, and then flows to the ventilation box. The air is blown into the room from the ceiling provided with the ventilation box. Therefore, it is possible to perform ventilation without feeling cold air, as in the case where air is directly taken from the ventilation gallery. In addition, since it is taken into the room from the ventilation box through the ventilation gallery and the heat storage ventilation duct, it is quiet without noise. Furthermore, since it fits inside the ceiling and only the vent of the ventilation box is exposed inside the room and only the ventilation gull is exposed outside the building, it is possible to design freely according to the appearance of the room or the building. Furthermore, this ventilation structure can be installed at low cost because it is a simple structure that connects the ventilation gallery provided on the side wall of the house and the ventilation box provided on the ceiling with a heat storage ventilation duct. Can be maintained.

Further, by providing a pipe fan at the ventilation opening of the ventilation box, it is possible to easily change from a ventilation structure of natural ventilation to a ventilation structure of forced ventilation, and this pipe fan is inexpensive and Even if it is not a specialist, it can be easily inserted into the ventilation opening of the ventilation box and constructed.
