  The engine 20 drives the generator 30. The engine 20 is integrally connected to the generator 30 and is configured to generate power by rotating the output shaft. The generator 30 is a three-phase AC generator that generates U-phase, V-phase, and W-phase AC power. The U-phase AC power, the V-phase AC power, and the W-phase AC power are AC powers having phases different from each other by 120 degrees, and the voltage is set to 100 V, for example. In addition, the voltage of the alternating current power of each phase is not limited to 100V, It can change suitably. The generated AC power of each phase is taken out from the outlet output unit 40.

  In the outlet output unit 40 of the first embodiment, as shown in FIGS. 1 and 2, four output units are arranged in the vertical direction and three output units are arranged in the horizontal direction, so that a total of 12 output units are arranged. Is arranged. Each output unit includes an outlet body 40a (see FIG. 9) into which a plug of a load device such as a lighting fixture, electric tool, or office machine is inserted, and an outlet cover 40b (see FIG. 9) that covers the outlet body 40a. Has been. In addition, although the hole which inserts the plug currently formed in the outlet main body 40a is three holes which can attach ground, two holes which do not attach ground may be sufficient, and the shape of the hole to insert is suitably It can be changed. Here, FIG. 8 is a diagram schematically showing a relationship between a circuit through which AC power of the U phase, the V phase, and the W phase flows and each output unit in the first embodiment.

  As shown in FIG. 8, four output units arranged in the vertical direction on the left side are connected to the circuit 41 through which the U-phase AC power generated by the generator 30 flows. These output units will be referred to as a first U-phase output unit u1, a second U-phase output unit u2, a third U-phase output unit u3, and a fourth U-phase output unit u4 in order from the lower side to the upper side. Also, four output units arranged in the vertical direction in the middle of the left and right are connected to the circuit 42 through which the V-phase AC power flows. These output units are referred to as a first V-phase output unit v1, a second V-phase output unit v2, a third V-phase output unit v3, and a fourth V-phase output unit v4 in order from the lower side to the upper side. Similarly, four output units arranged in the vertical direction on the right side are connected to the circuit 43 through which W-phase AC power flows. These output units are referred to as a first W-phase output unit w1, a second W-phase output unit w2, a third W-phase output unit w3, and a fourth W-phase output unit w4 in order from the lower side to the upper side. Thus, when a load device is connected to each U-phase output unit u1 to u4, U-phase AC power is supplied to the load device, and when each V-phase output unit v1 to v4 is connected to a load device, V-phase AC power is When supplied to the load device and connected to each of the W-phase output units w1 to w4, the W-phase AC power is supplied to the load device.

  In the engine generator 1, as described above, since the twelve output units u1 to u4, v1 to v4, and w1 to w4 are provided, a large number of load devices can be connected. Convenience can be improved. Further, since the U-phase output units u1 to u4, the V-phase output units v1 to v4, and the W-phase output units w1 to w4 are arranged in a line in the vertical direction as one group, this engine generator It is easy for the side managing 1 to manage each output unit. However, since many output parts u1-u4, v1-v4, w1-w4 are provided, there exist the following problems.

  That is, the user arbitrarily connects the load device to any of the output units u1 to u4, v1 to v4, and w1 to w4. For example, when the user wants to supply AC power to four load devices It is conceivable that the person connects the plugs of four load devices only to the U-phase output unit (first to fourth U-phase output units u1 to u4). In this case, only the U-phase AC power is extracted, and the load generated in the generator 30 is biased toward the U-phase. At this time, even if the four load devices are connected to the U-phase output units u1 to u4, the V-phase output units v1 to v4, and the W-phase output units w1 to w4 in a well-balanced state, the AC power can be taken out without any problem. In the case described above, the power generation capacity of the generator 30 cannot be fully used, and there may be a situation in which AC power cannot be taken out. In addition, the U-phase, V-phase, and W-phase voltages are unbalanced, which may hinder the use of the generator 30.

  Therefore, in the present embodiment, the outlet output unit 40 has a visual device structure that makes the person who connects the load equipment aware of the connection order so that the AC power of the U phase, the V phase, and the W phase is taken out in a balanced manner. Is provided. Here, FIG. 9 is an enlarged view of the outlet output unit 40 shown in FIG. As shown in FIG. 9, the visual contrivance structure of the first embodiment has different numbers written on the output units u1 to u4, v1 to v4, and w1 to w4, and the numbers are arranged in the horizontal direction on the right side. It is constituted by a value that increases in order as it goes to and increases toward the upper side in the vertical direction. That is, “1”, “2”, and “3” are sequentially written in the first U-phase output unit u1, the first V-phase output unit v1, and the first W-phase output unit w1, and the second U-phase output unit u2 and the second V-phase output unit. “4”, “5”, and “6” are sequentially written in v2 and the second W-phase output unit w2, and “7” is sequentially written in the third U-phase output unit u3, the third V-phase output unit v3, and the third W-phase output unit w3. “8” and “9” are written, and “10”, “11”, and “12” are written in order in the fourth U-phase output unit u4, the fourth V-phase output unit v4, and the fourth W-phase output unit w4.

The effect of 1st Embodiment is demonstrated.
According to the engine generator 1 of the first embodiment, the person who connects the load device is aware of the connection order so as to connect the load device toward the right side in the lateral direction. For example, when supplying AC power to four load devices, the plug of the first load device is connected to the first U-phase output unit u1, and the plug of the second load device is connected to the first V-phase output unit. Connected to v1, the plug of the third load device is connected to the first W-phase output unit w1, and the plug of the fourth load device is connected to the second U-phase output unit u2. Therefore, a plurality of load devices are not biased and connected to a certain one-phase output unit, and the generated AC power of each phase can be taken out in a balanced manner. As a result, it is possible to prevent a situation in which the power generation capacity of the generator 30 cannot be used sufficiently, and to prevent the U-phase, V-phase, and W-phase voltages from being unbalanced and hindering the use of the generator 30. .

  As a modification of the first embodiment, the numbers described in the output units may increase in order toward the left side while being lined up in the horizontal direction. Alternatively, the numbers described in each output unit may increase toward the lower side in the vertical direction. The numbers described in each output unit may be Roman numerals or Chinese numerals in addition to Arabic numerals, and may be in the order of letters (for example, alphabetical order), and can be changed as appropriate.
