  By the way, the structure where a generator and a gas cylinder are stored in one housing, ie, the structure which expands the housing | casing of the electric power generating apparatus of patent document 1 in the left-right direction, and arranges a generator and a gas cylinder inside is also considered. . In such a case, the lateral dimension of the housing is increased, and a space for opening the front door is required, so that a large installation dimension is required in the lateral direction and the front-rear direction. Conceivable.

  The objective of this invention is providing the energy supply unit which can be installed in a narrow ground while storing a fuel container and a generator in a housing | casing.

  The energy supply unit of the present invention includes a fuel container in which gas fuel is stored, a generator that generates power by burning the gas fuel, and a pipe for supplying the gas fuel from the fuel container to the generator. The fuel container, the generator, and a box-shaped casing for storing the piping, and the casing includes a container-side space for storing the fuel container, A partition portion that divides the generator-side space in which the generator is stored is provided, and the fuel container is disposed on the same side surface or the two opposite side surfaces of the housing between the container-side space and the outside of the housing.

When leaking from the fuel container 3, the container side space 2A is not filled.

  Next, the positional relationship and dimensions of the configuration inside the housing 2 will be described.

  As shown in FIGS. 4 and 5, the fuel container 3 and the generator 4 are juxtaposed in the X direction, and the fuel container 3 has dimensions in the X direction and the Z direction corresponding to the first space 2 </ b> C. The piping unit 5 has a container-side connecting pipe 52 connected near the upper end of the fuel container 3 and extends to the second space 2D. A meter 51 having a Z-direction dimension corresponding to the second space 2D is disposed. The connecting pipe 54 passes through the through hole 231 and protrudes outside the housing 2, while the generator connecting pipe 53 extends along the generator side surface 23 and passes through the through hole 271 formed in the horizontal partition portion 27 b.

  Next, the usage method of the generator 4 is demonstrated.

  Since the generator 4 generates exhaust gas and generates heat during power generation, the generator 4 needs to be operated outside the casing 2, and the generator-side door 23b is opened to be taken out of the casing 2 through the generator-side opening 23a. The operation is started by being connected to the generator connecting pipe 53 by the flexible pipe 6. At this time, the generator 4 supplies power by being connected to an electrical device by the power cord 7.

Therefore, it is possible to perform power supply and fuel supply by shortening the extension distance of the flexible tube 6 and the power cord 7. Further, since the generator connecting pipe 53 extends to the generator-side space 2B, the generator connecting pipe 53 and the generator 4 can be easily connected.

  Furthermore, since the transparent part 213 is formed on the front side surface 21 of the housing 2 so that the display part 51a of the meter 51 can be visually recognized, the display part 51a can be visually recognized without giving a margin to the space. Further, since the meter opening 211 having a size larger than that of the meter 51 is formed on the front side surface 21, the meter 51 can be inspected and replaced, and a space necessary for taking the meter 51 in and out can be increased. The volume can be reduced to about 51, and an increase in installation dimension in the Y direction can be suppressed.

  In addition, since each configuration has dimensions corresponding to the spaces 2A and 2B and is arranged inside the housing 2, the use efficiency of the space can be increased, and the size of the housing 2 can be increased. While preventing, the capacity | capacitance of the fuel container 3 can be enlarged.

Further, the gas meter 51, the flexible tube 6, and the power cord 7 may be stored outside the housing 2, and in such a configuration, if the size of the fuel container 3 in the Z direction is made smaller to match the generator 4. The size of the housing 2 in the Z direction can be reduced, and the housing 2 can be installed at a place where the installation size in the Z direction is limited (for example, below a protruding portion such as a bay window).

  In the embodiment, the container side opening 22a and the generator side opening 23a are closed by the container side door 22b and the generator side door 23b. However, as shown in FIG. And it is good also as a structure obstruct | occluded by the generator side shutter 23c.
