The technical object of the present invention is to reduce the installation area of a soundproof engine generator connected to a vertical water-cooled engine.

[0005]

[Means for Solving the Problems] Means for achieving the above objects will be explained below with reference to drawings shown in embodiments. That is, the present invention provides a soundproof vertical water-cooled engine generator having the above-mentioned basic structure, in which an engine compartment 3 is formed in the lower part of the soundproof case 10, and an exhaust chamber 5 is provided above the engine compartment 3 via a partition wall 4. A radiator 1 and a cooling fan 2 are arranged in the exhaust chamber 5, an engine E and a generator G are arranged in the engine compartment 3, an exhaust inlet 6 is opened in the partition wall 4, and the exhaust chamber 5 is
This is characterized in that an air exhaust outlet 7 is opened in the side wall 11 of the soundproof case 10 facing the soundproof case 10.

[0006]

[Function] An exhaust chamber 5 and an engine chamber 3 are formed in the upper and lower parts of the soundproof case 10, and the radiator 1 and the cooling fan 2 are arranged in the exhaust chamber 5. Since it is placed on top of the space above the
Unlike the prior art described above, the cooling fan 2, radiator 1, and exhaust duct 50 do not extend in series in front of the engine E, and the longitudinal length of the soundproof case 10 can be shortened.

In this case, the cooling air taken into the soundproof case 10 by the action of the cooling fan 2 enters the exhaust chamber 5 from the engine compartment 3 through the exhaust inlet 6, cools the radiator 1, and then exits the exhaust outlet. 7 to the outside of the soundproof case 10. In addition, the noise of the cooling fan 2 can be efficiently reduced by lining the exhaust chamber 5 with a sound deadening material.

[0008]

[Effects of the Invention] The exhaust chamber, which is a so-called dead space inside the soundproof case, is used, and the radiator and cooling fan are housed in the exhaust chamber and placed on top of the vertical water-cooled engine, so the front-to-back length of the soundproof case can be reduced. The engine generator can be shortened and the engine generator can be organized neatly, and the installation area of the soundproof engine generator can be reduced, allowing for effective use of work space.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 is a vertical right side view of a soundproof engine generator, Figure 2
is a cross-sectional plan view from above of the same engine generator.

[0010] The soundproof engine generator has a generator G coupled to the rear of a vertical water-cooled diesel engine E, and the whole is housed in a rectangular parallelepiped soundproof case 10. That is, as shown in FIG. 1, the upper and lower parts of the soundproof case 10 are partitioned into an engine compartment 3 and a ventilation compartment 12 via a partition wall 4.
As shown in FIG.
3 into a front ventilation chamber 5 and a rear ventilation chamber 8. As shown in FIG. 1, the engine compartment 3 on the lower side of the soundproof case 10
A control panel 16 is placed above the generator G, and a battery 17 is supported below it. A fan 2 is housed therein, and a fuel tank 14 is housed in a suction chamber 8 at the upper rear part.

As shown in FIG. 2, an exhaust inlet 6 is opened in the partition wall 4 facing the exhaust chamber 5, and an exhaust outlet 7 is opened in the front wall 11 of the soundproof case 10 facing the exhaust chamber 5. A fan support frame 18 is fixed to the rear of the radiator 1 via a fan shroud 15, and an electric motor 2 is attached to the fan support frame 18.
0 is installed, and the exhaust inlet 6 is installed in front of the electric motor 20.
Support the cooling fan 2 by facing it. The electric motor 2
0 is connected to the battery 17 in the engine compartment 3 so that power can be supplied thereto. In addition, the radiator 1 is connected to the lower engine E through the water pipe 1.
9, and is configured such that the cooling water flowing through the water jacket of the engine E can be radiated by the radiator 1. Reference numeral 21 is a detour plate installed upright in the exhaust chamber 5, and reference numeral 22 is a muffler facing the exhaust outlet 7 (see FIG. 2). As shown in FIG. 2, the right side wall 2 of the soundproof case 10 facing the air suction chamber 8
3, an air intake inlet 24 is opened in the partition wall 4 facing the air intake chamber 8, an air intake outlet 26 is opened in the partition wall 4 facing the air intake chamber 8, and a detour plate 25 is installed between the air intake inlet 24 and the air intake outlet 26.

The functions of the soundproof engine generator of this embodiment will now be explained. (1) Due to the action of the cooling fan 2, the air intake chamber 8 is opened from the air intake inlet 24.
The cooling air flowing into the interior passes through the detour plate 25 to the air intake outlet 2.
6 into the engine room 3 and cools the vertical water-cooled engine E and generator G, and also enters the exhaust chamber 5 through the air exhaust inlet 6 of the partition wall 4 to cool the radiator 1 and muffler 10. The air is discharged from the air outlet 7 to the outside of the soundproof case 10. In this case, the noise of the cooling fan 2 can be efficiently reduced by covering the inner wall of the exhaust chamber 5 with a sound deadening material such as glass wool or a foaming agent.

(2) Using the exhaust chamber 5, which was conventionally a so-called dead space inside the soundproof case 10, the radiator 1 and the cooling fan 10 are arranged in this exhaust chamber 5, and these are connected to the vertical engine E. Since the radiator 1 is placed in the upper space so to speak, the radiator 1 is placed in front of the engine E unlike the conventional technology.
The cooling fan 2 and the exhaust duct 50 do not protrude, and the front and rear length of the soundproof case 10 can be shortened to reduce the installation area of the engine generator.

The present invention is characterized in that the engine compartment 3 and the exhaust chamber 5 are arranged in a wrap-like manner above and below the soundproof case 10, and the radiator 1 and the cooling fan 2 are housed in the exhaust chamber 5. It is not essential to form the air suction chamber 8 above the soundproof case 10, and air may be taken directly from the engine compartment 3. Furthermore, instead of being rotatably driven by the transmission motor 20 as in the above embodiment, the cooling fan 2 disposed in the exhaust chamber 5 may be configured to be driven by a belt to the rotating shaft of the engine E disposed below. No problem.
