Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building in which a fuel cell device or a solar cell device is installed.

[0002]

2. Description of the Related Art With the development of the information society, various information devices such as terminal devices for digital lines are widely used.
Many of these various types of information devices use an AC adapter attached to an outlet provided in a commercial power supply circuit to generate low-voltage DC power, and use this low-voltage DC power.

However, when used in this way, when the commercial power supply fails, these various information devices become unusable. In preparation for such a power failure of the commercial power source, an emergency power source such as a fuel cell device or a solar cell device is provided, and the power source is switched to this emergency power source at the time of power failure. A building described in Japanese Patent Laid-Open No. 2000-224770 is known as a building provided with an emergency power source such as the fuel cell device and the solar cell device.

In this building, the electric power obtained from the fuel cell device, the solar cell device, and the commercial power source is stored in a storage battery as an emergency power source, and when the commercial power source fails, the commercial power source is switched to the emergency power source. The electric power stored in this storage battery is used. Of course, surplus power obtained from the fuel cell device and the solar cell device is also sold to a commercial power source. When using the electric power stored in this storage battery, use an inverter and use the same 100V as the commercial power supply.
The AC power of 100 V is converted to the AC power of 100 V and used instead of the commercial power supply.

When supplying electric power to a small-scale simple temporary building such as a nursing care unit building, a temporary housing, a temporary office, etc., a commercial power source is temporarily or permanently drawn into the building and this commercial power source is used. I'm using it. In addition, when supplying power to simple temporary buildings such as mountainous remote areas where it is difficult to draw commercial power, a small generator that operates the generator with an internal combustion engine to generate power is installed, and power is generated by this small generator. Power is also being supplied.

[0006]

However, the aforementioned Japanese Patent Laid-Open No. 20
The emergency power supply circuit disclosed in Japanese Unexamined Patent Publication No. 00-224770 has a problem that a power failure occurs at the moment of switching from a commercial power supply to an emergency power supply and various information devices malfunction. Further, when the electric power stored in the storage battery is used, it is converted into 100V AC electric power by using an inverter, but this conversion efficiency is low. In particular, when used as electric power for information equipment, etc., since most of the information equipment operates at low voltage DC, the electric power stored in the storage battery converted into AC 100V, which is the same as this commercial power supply, is used again with the adapter. Therefore, it is necessary to convert to low-voltage DC power, which further deteriorates the conversion efficiency.

When a commercial power source is temporarily or permanently drawn into a simple temporary building such as a nursing care unit building, a temporary housing, a temporary office, etc., and the power of this commercial power source is used, the simple temporary building is When the role ends, there is a problem that the equipment that draws in commercial power must be removed. Especially, in the case of a simple temporary building that is provided only during construction, such as a simple temporary building used by people engaged in power development work and dam construction that are installed in remote areas of the mountains, it is It is extremely difficult to pull in the power supply temporarily or permanently or remove the commercial power supply from an inconvenient place. In addition, when a small generator is used instead of temporarily installing or permanently installing a commercial power source, there is a problem in that power generation efficiency is poor, and it is noisy and cannot sleep.

In particular, when this simple temporary building is a nursing care unit building, it is often an emergency, and it is necessary to install the nursing care unit building and draw in commercial power as quickly as possible to care for an injured person or a sick person. However, it takes a considerable amount of time to draw in the commercial power source, which is inconvenient, and the power generation by a small-sized power generator is troublesome and has a bad influence on an injured person or a sick person.

Therefore, an object of the present invention is to prevent the information equipment from malfunctioning even when the commercial power source is out of power, and it is not necessary to pull in the commercial power source or install a small generator in the simple temporary building. It is to provide a building with an efficient power supply that connects to equipment.

[0010]

The present invention has been made to achieve the above object, and the invention according to claim 1 is a solar cell device comprising a fuel cell device or a storage battery and a solar cell. In a building provided with a power source, a distribution board is provided in the DC power supply, and a DC power supply circuit or an AC power supply circuit that uses the DC power supply as a source from the distribution board is provided separately from the commercial power supply circuit.

It may be a circuit or DC-
It may be a direct-current power supply circuit whose voltage is increased by a DC converter or the like.

According to a second aspect of the present invention, in a building provided with a DC power source which is a fuel cell device or a solar cell device including a storage battery and a solar cell, the DC power source is 100
A voltage control device for generating a voltage higher than V and a distribution board are provided, and a high-voltage DC power supply circuit using a DC power supply as a source from the distribution board is provided separately from the commercial power supply circuit.

The voltage control device used in the invention described in claim 2 is a device for converting a low voltage direct current into a high voltage direct current. Although there are various devices as such a voltage control device, a DC-DC converter having good conversion efficiency is preferable. Further, in the invention according to the second aspect, the electric equipment is used by being connected to the high-voltage DC power supply circuit higher than 100V. At this time, for example, in the case of an electric device that can be used even if it is directly connected to a high-voltage DC power supply circuit such as a lighting device for DC 200V, it can be used as it is, or a C for DC 4V can be used.
In the case of electric appliances such as chargers for D players, mobile phones, etc., which are used at a low DC voltage, a variable voltage control device with a high conversion efficiency such as a switching regulator is installed in this high-voltage DC power supply circuit. It may be used with a low voltage.

According to a third aspect of the present invention, in a building provided with a DC power source, which is a fuel cell device or a solar cell device including a storage battery and a solar cell, the building is a simple temporary building.

The simple temporary building according to the invention of claim 3 is a small-scale building that can be transported like a unit house and is used temporarily, and includes a nursing care unit building, a temporary housing, and a temporary office. Etc. are suitable simple temporary buildings. When the fuel supplied to the fuel cell used in the invention according to claims 1 to 3 is a hydrocarbon, city gas or the like may be supplied, or propane gas or liquefied natural gas or the like may be supplied to the fuel cell device. A cylinder filled with hydrocarbon may be provided and the hydrocarbon filled in the cylinder may be supplied.
The fuel supplied to the fuel cell may be a liquid such as alcohol, or may be hydrogen gas filled in a cylinder.

When the fuel is hydrocarbon, alcohol or the like, a reforming device is provided in the fuel cell unit to reform the hydrocarbon, alcohol or the like into hydrogen and carbon dioxide gas, and the hydrogen is used in the fuel cell. To supply. Since the simple temporary building of the invention according to claim 3 is often installed in a place without city gas, as in the invention according to claim 4,
A cylinder filled with propane gas or liquefied natural gas may be provided in the fuel cell device. Of course, claims 1 to
In the building described in 2, the fuel cell device may be provided with a cylinder filled with propane gas or liquefied natural gas.

That is, the invention described in claim 4 is defined by claim 1

A fifth aspect of the present invention relates to the invention according to any one of the first to third aspects, wherein the fuel cell device is provided with a device for utilizing heat generated from the fuel cell for heating or cooling. There is something.

The invention according to claim 6 relates to the invention according to claim 1 or 2, wherein an electric signal is superimposed on the DC power supply circuit or the high-voltage DC power supply circuit.

In the invention according to claim 6, when the electric signal superimposed on the DC power supply circuit or the high-voltage DC power supply circuit is used, if the device uses the DC power supply circuit or the high-voltage DC power supply voltage, Although they can be used as they are, many devices that use normal electric signals operate at a low DC voltage, such as ISDN telephones that operate at 12V DC. In such a case, it is necessary to reduce the DC current of the DC power supply circuit or the high-voltage DC power supply circuit to a low voltage by the variable voltage control device before use.

At this time, if the direct current is reduced to a low DC voltage by the variable voltage controller, the electric signal is erased and the electric signal cannot be used. It is advisable to separate and use the superimposed electrical signals before conversion.

The invention according to claim 7 relates to the invention according to claim 3, wherein the simple temporary building is provided with a communication function.

The communication function in the invention according to claim 7 means a device capable of communicating with a remote place, such as a mobile phone radio telephone, a PHS radio telephone and the like which can be connected to a public telephone network.
There are short-distance cordless telephones, in-house PHS telephones, and other wireless telephone units for extension wireless telephones.

(Operation) In the invention described in claim 1, in a building provided with a DC power source which is a fuel cell device or a solar cell device including a storage battery and a solar cell, a distribution board is provided in the DC power source. Since a DC power supply circuit or an AC power supply circuit that uses a DC power supply as a source from this distribution board is provided separately from a commercial power supply circuit, a DC power supply circuit or an AC power supply circuit that uses a DC power supply as a power source causes a power failure such as a personal computer. Then connect and use the electric appliances that are in trouble. Then, even if the commercial power supply fails, the DC power supply circuit or the AC power supply circuit that uses the DC power supply unrelated to the commercial power supply circuit will not fail, and the electric appliances will not stop or malfunction. .

In a refrigerator or the like, when a breaker of a distribution board cuts off due to a lightning strike or the like during an outing and a blackout occurs for a long time, food stored in the interior may be decomposed and annoyed by this direct current. If a direct-current power supply circuit or an alternating-current power supply circuit that uses the power supply circuit as a source is connected, such a situation does not occur and it is safe.
It should be noted that an electric appliance such as an oven that may temporarily lose power may be connected to a DC power supply circuit or an AC power supply circuit that uses this DC power supply as a source, but since a commercial power supply is generally inexpensive, Such an electric appliance that may temporarily lose power may be used by connecting it to a commercial power source.

In a second aspect of the present invention, in a building provided with a direct current power source which is a fuel cell device or a solar cell device including a storage battery and a solar cell, the direct current power source includes 10
Since a voltage control device that generates a voltage higher than 0 V and a distribution board are provided, and a high-voltage DC power supply circuit that uses a DC power supply as a source from this distribution board is provided separately from the commercial power supply circuit,
It has the following effects.

That is, since this high-voltage DC power supply circuit is provided separately from the commercial power supply circuit, it has substantially the same operation as the invention of claim 1. Further, as in the conventional case, in order to connect to a commercial power supply circuit, a low-voltage direct current obtained from a solar cell device, a fuel cell device, or the like is converted into 100 V AC at the same frequency (50 cycles or 60 cycles) as the commercial power supply by an inverter. When converted to, the conversion efficiency is low because the frequency is low. However, in the invention according to claim 2, since the high-voltage DC power supply circuit is separate from the commercial power supply, it is not necessary to make the frequency the same as that of the commercial power supply, and DC-
With a voltage control device such as a DC converter, the frequency can be made higher than that of the commercial power source to make it a high voltage, and then it can be converted to direct current.

Further, in the case of the same output, since the voltage is high, the current passing through the circuit is small, so that the power loss due to the electric resistance is reduced, and the lighting fixture for 200V or the like is used.
When an electric appliance that can be used at high voltage is used like a heating device for 00V, it is not necessary to convert the voltage, and electric power can be efficiently used. Further, conventionally, an AC adapter is used when a 100V AC is used as a low voltage DC of a personal computer or the like, but the conversion efficiency of this AC adapter is poor. However, in the invention according to the second aspect, it is possible to convert to a low voltage direct current by a high frequency switch type variable voltage control device such as a switching regulator having a high conversion efficiency.

As described above, since it is possible to improve the conversion efficiency for converting the low-voltage DC power supply to the high-voltage DC power supply, and to convert the high-voltage DC power supply to the low-voltage DC power supply, and to reduce the power loss due to power transmission, the total power consumption can be reduced. The loss can be reduced. Further, as described above, since the power loss can be reduced, the heat generated by the power loss is reduced and the cooling load in summer is reduced.

If an AC adapter is connected to an outlet and an electric device is connected to this outlet for use,
The heat generated by the AC adapter causes convection in the vicinity of the outlet and contaminates the surroundings of the outlet. However, according to the invention of claim 2, a variable voltage control device having a high conversion efficiency can be used without using the AC adapter, and heat is generated. As a result, the pollution around the outlet can be reduced.
Further, when a fluorescent lamp is connected to a conventional commercial power supply circuit and used, flicker and noise occur due to the alternating current. However, when a fluorescent lamp is connected to the DC power supply circuit of the invention according to claim 2, No flicker, no adverse effect on eyes, no noise and no need to provide a device for preventing noise.

In a third aspect of the present invention, in a building provided with a DC power source which is a fuel cell device or a solar pond device composed of a storage battery and a solar cell, since the building is a simple temporary building, this simple temporary installation is used. By simply transporting a building by a truck or the like and installing it at a desired place, it is possible to use electric power quickly and easily without drawing in commercial electric power.

Therefore, even in a place remote from a commercial power source such as in a remote area of a mountain and where it is difficult to pull in the commercial power source, the electric power can be easily brought into a usable state, and the labor and cost for pulling in the electric power can be omitted. it can. Conventionally, when electric power is used in a place away from a commercial power source such as a remote area in the mountains, a small generator is used to generate electric power, but there is a problem in that it is noisy due to noise. In particular, when the simple temporary building is a nursing care unit building, power generation by a small generator has an adverse effect on an injured person or a sick person in the nursing care unit building. However, the invention according to claim 3 does not have such a problem.

Further, when the simple temporary building is a nursing care unit building, it can be safely transported by carrying the nursing care tool installed in the simple temporary building. And when treating an injured person or a sick person, use the equipment installed in the care unit building as quickly as possible,
Although it is necessary to treat an injured person or a sick person, conventionally, it took a long time to pull in a commercial power source, and it could not be used during that time. However, in the invention according to claim 3, a simple temporary building is installed. It can be used immediately.

According to a fourth aspect of the present invention, in the fuel cell device according to any one of the first to third aspects,
Since the cylinder filled with propane gas or liquefied natural gas is provided, the fuel cell can generate power even in a place where city gas or the like cannot be obtained. Since the cylinder filled with the propane gas or the liquefied natural gas can be easily obtained, the cylinder can be easily provided in the fuel cell unit.

According to a fifth aspect of the present invention, in the fuel cell device according to any one of the first to third aspects,
Since a device for utilizing heat generated from the fuel cell for heating or cooling is provided, it becomes a building that can maintain an appropriate temperature in the building and can live easily, and energy generated by the fuel cell can be used. Energy required for air conditioning can be saved.

According to the invention of claim 6, claim 1 or 2
According to the invention described in the above, since an electric signal is superimposed on the DC power supply circuit or the high voltage DC power supply circuit, a communication line such as ISDN is connected to the DC power supply circuit or the high voltage DC power supply circuit with simple equipment. Can be used as an analog or digital communication path.

In addition, conventionally, when superimposing an electric signal such as ISDN on an alternating current of 100 V in a building, it is necessary to employ a high frequency superimposing or spread spectrum method which requires expensive equipment. If it is direct current as in the invention described in 6, the simple and inexpensive pulse transmission method can be adopted. Further, since the electric signal is superimposed on the DC power supply circuit or the high-voltage DC power supply circuit, it is not necessary to install a telephone line indoors, and this installation cost can be saved.

According to the invention of claim 7, in accordance with the invention of claim 3, since the simple temporary building has a communication function, it is not necessary to connect a telephone line, and the simple temporary building is not required. It is convenient because you can set up and communicate immediately. Conventionally, a mobile phone has been used as a means for communicating without being connected to a telephone line, but this mobile phone is not preferable because electromagnetic interference occurs. However, the invention according to claim 7 does not have this electromagnetic interference.

In particular, when this simple temporary building is a nursing care unit building, it is extremely important that it can be installed and can communicate immediately. However, if a mobile phone is used, it can be used for nursing care installed in the simple temporary building. The device will malfunction and cannot be used. However, in the invention of claim 7,
Without this, it can be used safely.

If the direct current power source is a fuel cell unit and the fuel used in this fuel cell is propane gas or liquefied natural gas filled in the cylinder, a communication function is attached to the meter of this cylinder. By making it possible to know the usage status of propane gas or liquefied natural gas at a remote place, it is convenient to avoid a power failure due to a shortage of fuel used in the fuel cell.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described with reference to examples. (Embodiment 1) FIG. 1 shows an embodiment of the present invention and is a circuit configuration diagram showing a DC power supply circuit provided in a building.

In FIG. 1, reference numeral 2 is a commercial power supply circuit.
Reference numeral 3 is a fuel cell device, and 4 is a DC power supply circuit which uses the fuel cell device 3 as a source. The commercial power supply circuit 2 and the DC power supply circuit 4 that uses the DC power supply device 3 as a source are separately provided in the building.

Then, the natural gas supplied from the LPG cylinder 32 is supplied to the reformer. Then, this reformer reforms hydrogen and carbon dioxide gas, and this hydrogen is supplied to the fuel cell 31 and chemically reacts with oxygen in the air to become water. The energy generated at this time becomes a DC power of 12 V and is supplied to the distribution board 41.

The DC power supply circuit 4 in the first embodiment
The electric power of the fuel cell device 3 is used for the solar cell device, but it is a solar cell device including a solar cell and a storage battery, and the electric power generated by the solar cell in the daytime is stored in the storage battery and stored in this storage battery. You may make it use electric power. Further, although the fuel cell 3 uses the LPG cylinder 31, the propane gas cylinder may be used without using the LPG cylinder 31. Alternatively, city gas may be supplied to the fuel cell device 3. Alternatively, hydrogen may be directly supplied to the fuel cell device 3 without providing the reformer.

The DC power supply circuit 4 using the fuel cell unit 3 as a power source is wired from the distribution board 41 to various places in the building 1, for example, the outlets 411, 412 and 413 shown in the drawing, or directly to electric appliances.

The DC power supply circuit 4 which uses the fuel cell device 3 as a power source has an AC voltage of 100 V or 200 through an inverter.
It may be an alternating-current power supply circuit with V, or a direct-current power supply circuit with direct current of 100 V or 200 V through a DC-DC converter. As described above, the DC power supply circuit 4 using the fuel cell device 3 as a source is connected to the electric appliances such as the refrigerator 42, the ISDN telephone 43, and the personal computer 44, which are troubled when the commercial power supply circuit 2 loses power. Even if 2 goes out of power, ISDN telephone 42, PC 44
Does not malfunction, and even if the breaker is shut off due to a lightning strike or the like while away, there is no adverse effect such as damage or decay of the preserved items stored in the refrigerator 43.

(Embodiment 2) FIGS. 2 and 3 show another embodiment of the present invention. FIG. 2 is a circuit configuration diagram showing a high voltage DC power supply circuit provided in a building, and FIG. 3 is an ISDN. It is a circuit block diagram which shows the circuit of the variable voltage control apparatus connected to a telephone.

Comparing the second embodiment shown in FIGS. 2 and 3 with the first embodiment shown in FIG. 1, it is different in that the DC power supply circuit is a high voltage DC power supply circuit 4a. Therefore, the commercial power supply circuit will be omitted and the high-voltage DC power supply circuit 4a will be described. The high-voltage DC power supply circuit 4a is a circuit that is wired from a distribution board (not shown) to outlets or the like provided in various places in the building, or directly to an electric appliance.

The high-voltage DC power supply circuit 4a controls the voltage of DC 12V power 40a obtained from the illustrated fuel cell device or DC 12V power 40a obtained from the solar cell device which is generated by the solar cell and stored in the storage battery. DC-D of device
Electric power converted to 200V DC by the C converter 41a is supplied. In addition, this high-voltage DC power supply circuit 4a,
The electric signal of the ISDN line 5a is the ISDN adapter 51.
In a, it is superimposed by the pulse transmission method. The high-voltage DC power supply circuit 4a is connected to various electric appliances that are troubled in the event of a power failure and electric appliances that do not require voltage conversion, such as fluorescent lamps for DC 200V.

For example, as shown in FIG. 2, this high-voltage DC power supply circuit 4a is provided with an outlet 42a equipped with a switching regulator (variable voltage controller), and the switching regulator of the outlet 42a equipped with this switching regulator converts it to 4V DC. To be done. A CD player 421a is connected to the outlet 42a with a switching regulator. In addition, this high-voltage DC power supply circuit 4a, DC200V
For fluorescent lamp 43a is connected.

Further, the high voltage DC power supply circuit 4a is provided with an outlet 44a with a switching regulator, and the outlet 4a with a switching regulator is provided.
It is converted to DC 4V by the 2a switching regulator. A CD player 441a is connected to the outlet 42a with a switching regulator.

The high voltage DC power supply circuit 4a is converted to DC 12V by the variable voltage controller 45a, and the ISDN telephone 451a is connected to the variable voltage controller 45a via DSU and TA. This variable voltage control device 4
As shown in FIG. 3, 5a includes a switching regulator 455a and a waveform shaping circuit 456a, and the high-voltage DC power supply circuit 4a includes the switching regulator 455a.
Before entering, the I superimposed on the high-voltage DC power supply circuit 4a
An electric signal of SDN is separated into a waveform shaping circuit 456a, and then converted into DC 12V by a switching regulator, and both are connected to an ISDN telephone 451a.

Next, the function and effect of the high voltage DC power supply circuit 4a will be described. Since the high-voltage DC power supply circuit 4a is separate from the commercial power supply as in the first embodiment, the CD player 421a and the like are not affected even if the commercial power supply circuit fails. Further, since this high-voltage DC power supply circuit 4a is separate from the commercial power supply, it is not necessary to make it the same frequency as the commercial power supply. Can be converted to. In this way, the voltage conversion efficiency can be improved.

Further, since the high-voltage DC power supply circuit 4a has a high voltage, the current passing through the wiring is small and the loss due to the electric resistance is small. Moreover, in the conventional commercial power supply circuit,
The conversion efficiency was poor because an AC adapter was used when a 100V AC was used as a low voltage DC of a personal computer or the like, but in the second embodiment, a low voltage DC is used by a variable voltage control device such as a switching regulator. Since it is converted into, the conversion efficiency is good.

Since the voltage conversion efficiency is good as described above, less heat is generated when the voltage is converted, and therefore the cooling load in summer is reduced. Also, DC 200V fluorescent lamp 43
When connecting to a, it is not necessary to convert the voltage, and power can be used efficiently. Also, this DC 200V
Since the fluorescent lamp 43a for use is not an alternating current, it has little flicker and does not adversely affect the eyes. Further, since there is no noise, the TV or telephone will not be damaged even if no noise prevention device is provided.

The high-voltage DC power supply circuit 4a has an ISDN
Since the electric signal of the telephone is superposed, it is not necessary to install the telephone line indoors, and since it is the high-voltage DC power supply circuit 4a, when superposing the electric signal, the conventional expensive high-frequency superposition and spread spectrum method are used. Instead, a simple and inexpensive pulse transmission method can be adopted.

(Embodiment 3) FIGS. 4 and 5 show another embodiment of the present invention. FIG. 4 is a perspective view showing a simple temporary building, and FIG. 5 is an enlarged view of portion A of FIG. It is sectional drawing shown.

This simple temporary building 1b can be used for various purposes. For example, it can be used as a temporary housing where workers stay in a place away from commercial power sources such as remote areas in the mountains or as a temporary office for office work, or as a care unit building for caring for a suddenly ill or injured person.

Next, the method of use and the effect of using the simple temporary building 1b in a temporary house or a temporary office will be described. When it is used for temporary housing, a bed or the like necessary for living is installed in the simple temporary building 1b. In addition, when it is used in a temporary office, a desk, chair, etc. necessary for office work are installed in the simple temporary building 1b.

Then, it is mounted on a truck, carried to a place where temporary housing or a temporary office such as a remote area of the mountain is installed, and installed in this place. By doing this, the bed, desk, etc. can be easily and safely transported, and by simply installing the simple erected building 1b in a remote area such as a mountain, it is fast and easy to use indoors without drawing in commercial power. Electric power generated by the fuel cell unit 31b can be used by connecting various electric appliances to the modular jack 7b. Therefore, it is possible to omit the work and cost for drawing in the used power.

Further, conventionally, there is also a method of using a small generator as a means for preventing commercial power from being drawn into a temporary housing or a temporary office in such a remote area of a mountain. However, the fuel cell unit 3b does not generate such noise. Further, since the wireless telephone unit 6b is provided, it is not necessary to install a telephone line, the installation cost for connecting the telephone line is eliminated, and it is possible to make a telephone call immediately after installation, which is convenient.

Further, since the fuel cell device 3b is provided with the LPG cylinder 32b, it is possible to generate power even in a place where city gas or the like cannot be obtained. Also, since this LPG cylinder 32b can be easily obtained,
