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 that it is hardly used 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. Along with being provided, this ventilation box is provided with ventilation holes at opposing positions, and the interior is divided into two air chambers so as to partition the two ventilation holes, and from these ventilation holes to a position facing the side wall of the house. The heat storage ventilation duct is extended over the provided ventilation gallery. Further, a pipe fan is provided at each of the ventilation openings.

[0014]

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

FIG. 1 shows an outline of the entire structure of a ventilation structure of a residential building 1, and FIG. 2 shows a construction state of the ventilation structure.

That is, this ventilation structure is configured such that a heat storage ventilation duct 4 is connected between a ventilation box 2 divided into two air chambers and two ventilation galleries 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 divided into two air chambers 2a and 2b by a partition plate 22 provided in the ventilation box 2 so as to divide the outlet 20 into two. 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 air outlet cover 21 may be provided with an air filter (not shown) or the like in order to prevent pollen and dust from entering the room 13. In the ventilation box 2, pipe-shaped ventilation ports 23 are provided so as to communicate with the two air chambers, respectively.
As shown in FIG. 3, a power outlet 24 for a power plug 51 of the pipe fan 5 is provided in each of the two air chambers in case the pipe fan 5 is attached to these ventilation ports 23. This ventilation box 2 has a ventilation gallery 3
Further, since it is for taking in the outside air from the heat storage ventilation duct 4 into the room 13, the shape is not particularly limited. 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 port 23, it is preferable to use one that is elongated in the axial direction of the ventilation port 23. For example, as shown in FIG. 4A, two air chambers 2a and 2
b may be a ventilation box 2 connected in the longitudinal direction, or as shown in FIG. 4B, a ventilation box 2 in which two air chambers 2a and 2b are adjacent to each other.

The ventilation gallery 3 is located above the ceiling 14 of the residential building 1.
The outer wall 1 at the opposite position of the residential building 1 so as to communicate with
5 are provided respectively.

The heat storage ventilation duct 4 is connected to the ventilation box 2
Are connected so as to connect between the two ventilation holes 23 provided at the two locations and the two ventilation galleries 3 respectively. 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, in a case where 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 one ventilation gallery 3 located on the windward side, and the heat storage ventilation duct 4 is provided. When the air passes through the ceiling box 14, it is heated to the atmospheric temperature of the ceiling space 14, then flows into one air chamber 2 a of the ventilation box 2, and from the ceiling surface 11 provided with the ventilation box 2 to the room 13.
Is blown out. Therefore, unlike the case where the outside air is directly taken in from the ventilation gallery 3, the user does not feel cold. In addition, since the airtightness of the recent residential building 1 has been improved, the pressure of the room 13 increases due to the inflow of the outside air. Therefore, the other air chamber 2b of the ventilation box 2
After that, smooth natural exhaust is performed through the heat storage ventilation duct 4 to the other ventilation gallery 3 located on the leeward side. At this time, since the air exhausted from the room 13 is heated by the indoor heating, when passing through the heat storage ventilation duct 4, heat is radiated to the heat storage ventilation duct 4 and after the heat storage ventilation duct 4 is heated. Exhausted. Then, the heat stored in the heat storage ventilation duct 4 is used to warm the taken-in outside air when the outside air is taken in later. 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. Further, the inside of one ventilation box 2 is divided into two air chambers 2a, 2a
b, and the ventilation box 2 for each air supply and exhaust is not required, so that the construction can be performed very easily using the empty space of the ceiling surface 11 rationally.

As shown in FIG. 3, this ventilation structure has one or both of the ventilation openings 2 of the ventilation box 2.
The pipe fan 5 may be attached to 3 (both ventilation ports 23 in the present embodiment) and 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. The installation of the pipe fan 5 is simply performed by
By inserting the pipe fan 5 into the power outlet 24 of the ventilation box 2 by inserting the power supply plug 51 of the pipe fan 5 into the ventilation fan 2, the construction can be easily performed without calling a specialist. In this case, the operation of the pipe fan 5 is controlled by the control device 50 provided in the room 13.
Air supply and exhaust may be controlled automatically, or may be manually operated as desired.

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. Further, even when the pipe fan 5 is attached, the power supply of the pipe fan 5 can be easily removed by unplugging the power outlet 24 and pulling out the pipe fan 5 from the ventilation port 23, so that maintenance can be easily performed. it can.

[0024]

As described above, according to the present invention, among the ventilation galleys provided at the opposing positions on the side wall of the house,
The air blown from one ventilation gallery passes through the heat storage ventilation duct, flows from one ventilation opening to the ventilation box, and is blown into the room from the ceiling provided with the ventilation box. Further, since the indoor pressure is increased by the air blown from the outside, the indoor air is discharged from the other ventilation gallery through the heat storage ventilation duct from the other ventilation port of the ventilation box. In this way, since the ventilation gallery is provided at a position facing the side wall of the house, when air is blown from one ventilation gallery that is windward,
Since the air is discharged from the other ventilation gallery that is leeward, smooth natural ventilation can be performed even in a highly airtight house. Moreover, when this natural ventilation is performed, the air blown into the room is warmed to the ambient temperature behind the ceiling when passing through the heat storage ventilation duct, and the air discharged to the outside is cooled by the heat storage ventilation duct. When passing through, the heat is released to the heat storage ventilation duct and then discharged to the outside.Therefore, as in the case of directly taking in or discharging from the ventilation gallery, heat is efficiently ventilated without wasting the heat of indoor heating. can do. 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. In particular, since the ventilation box may be constructed with one ventilation box divided into two air chambers, construction costs can be reduced.

Further, by providing a pipe fan in 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.
