Description

The present invention relates to a ventilation device that is installed in a through hole that penetrates the wall of a building.

There is a system in which a power generating device is installed in a facility such as a house, and power can be supplied from the power generating device in the event of a power grid blackout. For example, Patent Document 1 (JP Patent Publication 2010-259170) describes a system that supplies the output of a power generating device operating independently to an independent operation outlet in the event of a power grid blackout.

In order to use electrical equipment within the facility when the power generation equipment is operating independently, an independent operation outlet as described above must be installed within the facility. However, since power generation equipment is usually installed outdoors, the problem arises as to what to do about the wiring route between the outdoor power generation equipment and the indoor independent operation outlet. In particular, when a power generation equipment is installed on the balcony of an apartment building, the outdoors and the indoors are separated by a concrete wall of the building, so the problem arises as to what to do about the wiring route between the outdoor power generation equipment and the indoor independent operation outlet.

Patent document 2 (JP Patent Publication 2006-333633) describes a through-hole device with a wiring pipe, in which a wiring pipe is provided inside a through-hole formed in the wall of a building, such as an air conditioning duct, a ventilation fan, or a ventilation opening, along the axial direction of the through-hole. The inside of the through-hole around the wiring pipe is filled with a sealant such as putty. By installing a through-hole device with a wiring pipe of this configuration in a through-hole formed in the wall of a building and passing a wiring cable or the like inside the wiring pipe as necessary, wiring that spans between the outdoors and the indoors can be installed.

JP 2010-259170 A JP 2006-333633 A

When the through-hole device with wiring piping described in Patent Document 2 is installed in a through-hole formed in the wall of a building, the through-hole is filled with the wiring piping and a filler that is filled around the wiring piping. As a result, the through-hole cannot be used as an air flow path for ventilation, etc.

The present invention was made in consideration of the above problems, and its purpose is to provide a ventilation device that can be installed with wiring spanning between indoors and outdoors.

Another characteristic configuration of the ventilation device according to the present invention is a ventilation device provided in a through hole penetrating a wall of a building,
Equipped with an indoor ventilation section and an outdoor ventilation section,
the indoor side ventilation section has an indoor side cylindrical body inserted into the through hole, and an indoor side flange provided so as to protrude radially outward from an end of the indoor side cylindrical body, and an indoor side wiring space is formed in the indoor side cylindrical body and the indoor side flange, through which wiring can be passed from the indoor side cylindrical body to the indoor side flange without blocking the internal space of the indoor side cylindrical body,
The outdoor ventilation section has an outdoor cylindrical body that is inserted into the through hole, and an outdoor flange that is arranged to protrude radially outward from the end of the outdoor cylindrical body, and an outdoor wiring space is formed in the outdoor cylindrical body and the outdoor flange that allows wiring to pass between the outdoor cylindrical body and the outdoor flange without blocking the internal space of the outdoor cylindrical body.

According to the above characteristic configuration, wiring spanning between the indoor and outdoor spaces can be installed using the indoor wiring space formed in the indoor tubular body and the indoor flange that constitute the indoor ventilation section, and the outdoor wiring space formed in the outdoor tubular body and the outdoor flange that constitute the outdoor ventilation section. In addition, since the indoor wiring space is formed without blocking the internal space of the indoor tubular body, and the outdoor wiring space is formed without blocking the internal space of the outdoor tubular body, the through holes formed in the wall can continue to be used as air flow paths for ventilation.

Another characteristic feature of the ventilation device of the present invention is that the indoor flange is provided with an electrical outlet that can be connected to wiring that is passed through the indoor wiring space.

According to the above characteristic configuration, if the indoor flange of the indoor ventilation section is placed on the indoor side of the wall of the building, an electrical outlet can be installed indoors to connect to wiring passing through the indoor wiring space of the indoor ventilation section and the outdoor wiring space of the outdoor ventilation section. Therefore, by inserting an electrical plug connected to an electrical device installed indoors into the electrical outlet, it is possible to supply power to the electrical device, which is supplied from a power generation device installed outdoors to the electrical outlet via wiring passing through the outdoor wiring space and the indoor wiring space.

Another characteristic feature of the ventilation device of the present invention is that it is equipped with a connecting section that connects the indoor ventilation section and the outdoor ventilation section.

According to the above characteristic configuration, the indoor ventilation section and the outdoor ventilation section are integrated by the connecting section, so that the indoor ventilation section and the outdoor ventilation section can be prevented from falling off the wall.

Another characteristic feature of the ventilation device according to the present invention is that the indoor ventilation section has a plurality of spaces for the indoor wiring, and the outdoor ventilation section has a plurality of spaces for the outdoor wiring.

The above characteristic configuration allows multiple wiring to be installed in the through hole area.

Another characteristic feature of the ventilation device of the present invention is that an electromagnetic shield is provided in at least one of the indoor wiring space and the outdoor wiring space.

The above characteristic configuration can prevent interference caused by electromagnetic waves between multiple wirings.

FIG. 13 is a diagram showing the configuration of a ventilation device according to a third embodiment.

First Embodiment
Hereinafter, a ventilation device V1(V) according to a first embodiment of the present invention will be described with reference to the drawings.
Fig. 1 is a diagram showing an installation form of a ventilation device V of a first embodiment. As shown in the figure, a distribution board 2 connected to a power system 1 is provided indoors in a building, and a plurality of power lines 3 extend from a branch breaker (not shown) provided in the distribution board 2. An electric device 10 is directly connected to the power line 3, or an electric outlet is connected to the power line 3. In the example shown in Fig. 1, an outdoor outlet 4 provided outdoors as an electric outlet is connected to one of the power lines 3 connected to the distribution board 2.

A power generation device 6 is provided outdoors. The power generation device 6 can output generated power to the grid-connected output wiring 7 or the independent output wiring 8.

For example, when the power generation device 6 is in a normal state in which power is normally supplied from the power grid 1 to the distribution board 2 and the power line 3, the power generation device 6 performs grid-connected operation to output generated power to the grid-connected output wiring 7. In the example shown in FIG. 1, the electric plug 5 connected to the grid-connected output wiring 7 is connected to the outdoor outlet 4, so the generated power of the power generation device 6 that is supplied to the grid-connected output wiring 7 is supplied to the power line 3.

When there is an abnormal state (such as a power outage) in which power is not normally supplied from the power grid 1 to the distribution board 2 and the power line 3, the power generating device 6 can perform independent operation to output generated power to the independent output wiring 8 electrically disconnected from the power grid 1. In the example shown in FIG. 1, the independent output wiring 8 is connected to an electrical outlet 24 provided in the ventilation device V. Therefore, when a power outage occurs and the power generating device 6 performs independent operation and can output power to the independent output wiring 8, residents can use the power supplied from the power generating device 6 to operate the electrical device 10 by connecting the electrical plug 12 connected to the wiring 11 of the electrical device 10 to the electrical outlet 24.

The ventilation device V is installed in a through hole 9a that penetrates the wall 9 of the building. This ventilation device V has a cylindrical body 21 that is inserted into the through hole 9a, and a flange portion 22 that is provided so as to extend radially outward from the end of the cylindrical body 21. The shape of the flange portion 22 that fits along the wall surface on the indoor side can be designed as appropriate. The cylindrical body 21 and the flange portion 22 are formed with a hollow wiring space 23 that allows wiring to pass between the cylindrical body 21 and the flange portion 22 without blocking the internal space 21a of the cylindrical body 21. For example, in the example shown in FIG. 1, a tunnel-shaped portion is formed at the bottom of the cylindrical body 21, and a hole is formed in the member that constitutes the flange portion 22, and the tunnel-shaped portion and the hole portion become the wiring space 23. In the example shown in FIG. 1, the wiring 8 for independent output is passed through the wiring space 23.

The length of the cylindrical body 21 can be set as appropriate. For example, as shown in FIG. 1, the cylindrical body 21 may be long enough to penetrate the wall 9 and protrude to the outside, or the cylindrical body 21 may be long enough to remain inside the wall 9 and not protrude to the outside.

The flange 22 is provided with an electrical outlet 24 that can be connected to the wiring that is passed through the wiring space 23. For example, in the example shown in FIG. 1, the electrical outlet 24 is embedded in the member that constitutes the flange 22. The independent output wiring 8 that is passed through the wiring space 23 is connected to the electrical outlet 24. Therefore, when the power generation device 6 is operating independently and can output power to the independent output wiring 8, residents can receive power generated by the power generation device 6 by connecting the electrical plug 12 connected to the wiring 11 of the electrical device 10 to the electrical outlet 24 installed indoors.

As described above, the wiring space 23 formed in the tubular body 21 and flange 22 that constitute the ventilation device V1 can be used to install wiring that spans between indoors and outdoors. In addition, since the wiring space 23 is formed in the tubular body 21 and flange 22 without blocking the internal space 21a of the tubular body 21, the through hole 9a formed in the wall 9 can continue to be used as an air flow path for ventilation.

Second Embodiment
The ventilation device V2 (V) of the second embodiment differs from the above embodiment in that it is composed of an indoor device and an outdoor device. The ventilation device V2 of the second embodiment will be described below, but the description of the same configuration as the above embodiment will be omitted.

Figure 2 is a diagram showing the configuration of a ventilation device V2 of the second embodiment. Note that in Figure 2, the distribution board 2 and electrical equipment 10 installed indoors, and the power generation device 6 installed outdoors are omitted. As shown in the figure, the ventilation device V2 is installed in a through hole 9a that penetrates a wall 9 of a building. The ventilation device V2 includes an indoor ventilation section 30 installed on the indoor side and an outdoor ventilation section 40 installed on the outdoor side.

The indoor ventilation section 30 is provided in a through hole 9a that penetrates the wall 9 of the building. Specifically, the indoor ventilation section 30 has an indoor cylindrical body 31 that is inserted into the through hole 9a, and an indoor flange 32 that is provided so as to extend radially outward from the end of the indoor cylindrical body 31. In other words, the indoor flange 32 is shaped to fit the wall surface on the indoor side. The indoor cylindrical body 31 and the indoor flange 32 have an indoor wiring space 33 that can pass wiring between the indoor cylindrical body 31 and the indoor flange 32 without blocking the internal space 31a of the indoor cylindrical body 31. For example, in the example shown in FIG. 2, a tunnel-shaped portion is formed at the bottom of the indoor cylindrical body 31, and a hole is formed in the member that constitutes the indoor flange 32, and the tunnel-shaped portion and the hole portion become the indoor wiring space 33.

The cylindrical space of the indoor flange 32 connected to the indoor cylindrical body 31 can be opened and closed by the cover member F. In this embodiment, the cover member F is attached to an extension mechanism 36 that can extend and retract along the axial direction of the through hole 9a. The extension mechanism 36 is fixed to a frame 37 provided on the inner surface of the indoor flange 32. In addition, a filter 38 that can capture foreign matter that attempts to pass through the through hole 9a is provided in the cylindrical space of the indoor flange 32. The indoor flange 32 is provided with an electrical outlet 34 that can be connected to the wiring that passes through the wiring space 23. For example, in the example shown in FIG. 2, a hole is formed in the member that constitutes the indoor flange 32, and the electrical outlet 24 is fitted into the hole.

The outdoor ventilation section 40 is provided in a through hole 9a that penetrates the wall 9 of the building. Specifically, the outdoor ventilation section 40 has an outdoor cylindrical body 41 that is inserted into the through hole 9a, and an outdoor flange 42 that is provided so as to extend radially outward from the end of the outdoor cylindrical body 41. In other words, the outdoor flange 42 is shaped to fit the outdoor wall surface. The outdoor cylindrical body 41 and the outdoor flange 42 have an outdoor wiring space 43 that can pass wiring between the outdoor cylindrical body 41 and the outdoor flange 42 without blocking the internal space 41a of the outdoor cylindrical body 41. For example, in the example shown in FIG. 2, a tunnel-shaped portion is formed at the bottom of the outdoor cylindrical body 41, and a hole is formed in the member that constitutes the outdoor flange 42, and the tunnel-shaped portion and the hole portion become the outdoor wiring space 43. A lattice 44 is provided in the cylindrical space of the outdoor flange 42 to prevent foreign objects from entering the through hole 9a. Furthermore, a cover member 46 is provided on the outdoor flange 42 outside the lattice 44 to prevent the intrusion of rain and other elements.

The lengths of the indoor side cylindrical body 31 and the outdoor side cylindrical body 41 can be set as appropriate. For example, as shown in FIG. 2, the indoor side cylindrical body 31 and the outdoor side cylindrical body 41 may be long enough so that they do not come into contact with each other, or they may be long enough so that they come into contact with each other.

The ventilation device V2 has a connecting part C that connects the indoor ventilation part 30 and the outdoor ventilation part 40. In this embodiment, the connecting part C has a detachment prevention member 35, a detachment prevention member 45, a support 50, and a nut 51.

Figure 3 is a view of the shape of the anti-removal member 45 of the outdoor ventilation section 40 as viewed from the outdoor side, and Figure 4 is a view of the shape of the anti-removal member 35 of the indoor ventilation section 30 as viewed from the indoor side. As shown in Figures 2 to 4, the anti-removal member 35 is fixed to the indoor flange 32. The anti-removal member 45 is fixed to the outdoor flange 42. One end of the support 50 (indoor side) is fixed to the anti-removal member 35, and the other end of the support 50 (outdoor side) is passed through the hole 45a of the anti-removal member 45. The support 50 and the anti-removal member 45 are then fixed by the nut 51. In this way, the indoor ventilation section 30 and the outdoor ventilation section 40 are installed in the through hole 9a while being connected by the connecting part C. Therefore, the indoor ventilation section 30 and the outdoor ventilation section 40 are integrated by the connecting section C, so that the indoor ventilation section 30 and the outdoor ventilation section 40 can be prevented from falling off the wall 9.

The independent output wiring 8 connected to the power generation device 6 passes through the outdoor wiring space 43 provided in the outdoor ventilation section 40 and the indoor wiring space 33 provided in the indoor ventilation section 30 and is connected to the electrical outlet 34. As a result, when the power generation device 6 is operating independently and can output power to the independent output wiring 8, residents can receive power generated by the power generation device 6 by simply connecting the electrical plug 12 connected to the wiring 11 of the electrical device 10 to the electrical outlet 34 installed indoors.

As described above, the indoor wiring space 33 formed in the indoor side tubular body 31 and the indoor side flange 32 constituting the indoor side ventilation section 30, and the outdoor wiring space 43 formed in the outdoor side tubular body 41 and the outdoor side flange 42 constituting the outdoor side ventilation section 40, can be used to install wiring spanning between indoors and outdoors. In addition, the indoor wiring space 33 is formed without blocking the internal space 31a of the indoor side tubular body 31, and the outdoor wiring space 43 is formed without blocking the internal space 41a of the outdoor side tubular body 41, so the through hole 9a formed in the wall 9 can continue to be used as an air flow path for ventilation.

Third Embodiment
The ventilation device V3 (V) of the third embodiment differs from the above-mentioned embodiments in that a plurality of wires can be passed through the ventilation device V3. The following describes the ventilation device V3 of the third embodiment, but the description of the same configuration as the above-mentioned embodiment is omitted.

Figure 5 is a diagram showing the configuration of the ventilation device V3 of the third embodiment. Note that in Figure 5, the distribution board 2 and electrical equipment 10 installed indoors and the power generation device 6 installed outdoors are omitted. As shown in the figure, the indoor ventilation section 30 has multiple indoor wiring spaces 33, 39 through which wiring can be passed, and the outdoor ventilation section 40 has multiple outdoor wiring spaces 43, 47 through which wiring can be passed.

In the example shown in FIG. 5, the indoor wiring space 33 and the outdoor wiring space 43 are provided on the bottom side of the through hole 9a, and the indoor wiring space 39 and the outdoor wiring space 47 are provided on the ceiling side of the through hole 9a. Then, for example, the independent output wiring 8 is passed through the indoor wiring space 33 and the outdoor wiring space 43. In addition, other wiring 53 can be passed through the indoor wiring space 39 and the outdoor wiring space 47. For example, the wiring 53 can be a communication line for communicating information between the power generation device 6 and a device installed indoors.

It is also preferable to provide an electromagnetic shield to block electromagnetic waves in at least one of the indoor wiring spaces 33, 39 and the outdoor wiring spaces 43, 47. In the example shown in FIG. 5, a tubular electromagnetic shield 52 is installed to span both the indoor wiring space 39 and the outdoor wiring space 47. Wiring 53 is then passed through the inside of the electromagnetic shield 52. This makes it possible to prevent interference caused by electromagnetic waves between multiple wirings.
