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]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a ventilation structure for a residential building according to the present invention comprises a pair of ventilation vents formed on a ceiling surface of the residential building from the ceiling surface toward a room. A box is provided, and a heat storage ventilation duct extends from a ventilation opening formed in each of the ventilation boxes to a ventilation gallery provided at a position facing the housing side wall. Further, a pipe fan is provided at each of the ventilation openings.

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 by connecting a heat storage ventilation duct 4 between a pair of ventilation boxes 2 and a 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 into two openings 12 provided on the ceiling surface 11 of the residential building 1, and attached so that the outlet 20 is located on the ceiling surface 11. The air outlet 20 has a grid-shaped or mesh-shaped removable air outlet cover 21.
Is provided. As the outlet cover 21, the indoor 1
An air filter (not shown) or the like may be provided to prevent pollen and dust from entering the device 3. Further, a pipe-shaped ventilation port 22 is provided in the ventilation box 2, and as shown in FIG. 3, a power plug 51 of the pipe fan 5 is prepared in case the pipe fan 5 is attached to the ventilation port 22. Power outlet 23 is provided. The ventilating box 2 is provided with the outside air from the ventilation gallery 3 and the heat storage ventilating duct 4 in the room
The shape is not particularly limited because it is intended to be incorporated into the device. Therefore, the room 13
The ventilation box 2 designed freely according to the design, space, etc. of the ceiling surface 11 can be used.
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.
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 between the ventilation openings 22 of the two ventilation boxes 2 and the ventilation gallery 3 at the two locations. 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, this wind is taken in from one ventilation gallery 3 located on the windward side, and the heat storage ventilation duct 4 is provided. After passing through the ceiling, it is heated to the atmospheric temperature of the ceiling space 14, flows into one ventilation box 2, and is blown out into the room 13 from the ceiling surface 11 provided with the ventilation box 2. 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. Accordingly, smooth natural exhaust is performed from the other ventilation box 2 to the other ventilation gallery 3 located on the leeward side through the heat storage ventilation duct 4. 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, when the heat stored in the heat storage ventilation duct 4 takes in outside air later,
It is used to warm the outside air. 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.

As shown in FIG. 3, this ventilation structure is used as a mechanical ventilation device by attaching a pipe fan 5 to one or both ventilation boxes 2 (in this embodiment, both ventilation boxes 2). You may. 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 pipe fan 5 can be attached by simply inserting the pipe fan 5 into the ventilation port 22 and inserting the power supply of the pipe fan 5 into the power outlet 23 in the ventilation box 2 without calling a specialist. It can be easily constructed. Also, in this case, the operation of the pipe fan 5 is
The air supply and exhaust may be automatically controlled by the control device 50 provided in 3, 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. 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.

Further, even when the ventilation structure functions as a natural ventilation device without the pipe fan 5 as shown in FIG. 1, the pipe fan 5 is mounted as shown in FIG. Even when functioning as a ventilation device, air is supplied and exhausted from two ventilation boxes 2 provided at separate positions in the room 13, so that the outside air taken in from one ventilation box 2 is supplied to the room 13. After sufficient circulation, air can be exhausted from the other ventilation box 2 and the ventilation efficiency can be improved.

[0025]

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 outside the room passes through the heat storage ventilation duct when doing,
After the heat is released to the heat storage ventilation duct, it is discharged to the outside, so that it is possible to ventilate with high heat efficiency without wasting the heat of indoor heating, as in the case of directly taking in or discharging from the ventilation gallery. . In addition, since a pair of ventilation boxes is provided, if the positions of these ventilation boxes are respectively set at distant locations in the room, fresh air taken into the room from one ventilation box will be the other. Can be prevented from being immediately discharged from the ventilation box, and the ventilation efficiency can be enhanced by sufficiently stirring and convection the room air. Furthermore, 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.

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, Even if it is not a specialist, it can be easily inserted into the ventilation opening of the ventilation box and constructed.
