[0003]

[Problems to be solved by the device]

 By the way, the following problems have been pointed out in such a conventional example. First of all, there was a local lack of cooling. That is, since the outer box 3 functions as a soundproof, the air supply port 1 and the exhaust port 2 are also provided as far away as possible from the engine 4, the generator 5, etc. that generate noise. Therefore, it was pointed out that the formed air flow A is less likely to hit the engine 4, the generator 5, etc. smoothly and, in particular, it deviates from the locally required cooling point where the temperature is high. For example, a portion of the engine 4 through which engine oil flows is located at the lower portion thereof, but such a lower portion of the engine 4 tends to come off the air flow A and is difficult to be cooled, so that the engine oil is used for a predetermined amount of time. The temperature was exceeded and it became unusable.

Secondly, as a countermeasure against such a local cooling shortage, first, a fan 6 is specially added for such a cooling required portion, for example, for cooling the engine oil under the engine 4. It was However, such a measure has a drawback that the configuration becomes complicated and the cost becomes high. Further, as a countermeasure against such a local cooling shortage, the rotation of the engine 4 has been slowed down, but with this, the power generation capacity of the private power generator is lowered.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, and provides an air guide tube having one end and the other end arranged in a predetermined manner. Therefore, firstly, it is possible to locally cool the cooling-needed part, and secondly, this is to propose an in-house power generation device that can be easily and easily realized without any problem in the power generation capacity. To do.

[0006]

[Means for Solving the Problems]

 The technical means of the present invention for achieving this object are as follows. That is, in this private power generator, an engine, a generator and the like are housed in a soundproof outer box having an air supply port and an exhaust port, and a fan is attached. An air guide tube is provided, and one end of the air guide tube is opened to the outside through an air supply hole provided in the outer box, and the other end is opened at an appropriate position near the engine and the generator. is doing.

[0007]

[Action]

 Since the present invention comprises such means, it operates as follows. This private power generator is provided with a wind guide tube whose one end and the other end are arranged in a predetermined manner. Then, when the fan is driven to rotate during use, first, air flows in from the air supply port of the outer box and forms a flow of air toward the exhaust port, so that the engine, generator, etc. To be cooled. Along with this, air also flows in from the air supply hole of the outer box, and after the air is guided from one end to the other end of the air guide pipe, a flow of air is also formed toward the exhaust port. Therefore, firstly, the flow of air through the air guide pipe enables efficient, direct, and reliable cooling of locally-cooled areas such as the engine and the generator, where the temperature is high. Secondly, the cooling of such cooling-needed areas is realized easily and easily by the air guide tube without affecting the power generation capacity.

【Example】

 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. FIG. 1 shows an embodiment of the present invention. (1) is a perspective view and (2) is a front sectional view.

In this private power generator, an engine 4, a generator 5, etc. are housed in a soundproof outer box 3 having an air supply port 1 and an exhaust port 2, and a fan 6 is attached. .. That is, the outer box 3 has a box-like shape including both side walls, a ceiling, front and rear walls, a floor, etc., and soundproof glass wool, sponge, etc. are attached to the inner surfaces of the outer box 3 and the internal engine 4, generator 5 and so on. It is designed to prevent noise from leaking to the outside as much as possible. Further, the air supply port 1 and the air exhaust port 2 are also provided as far as possible from the engine 4, the generator 5, etc. in consideration of the soundproof surface. Inside the outer box 3, an engine 4 which is an oil-type prime mover, a generator 5 which uses the rotation of the engine 4 to generate electric power, and the like are housed. Reference numeral 7 is a partition wall for further partitioning the inside of the outer box 3 as described above. An opening 8 is formed in the center of the partition wall 7, and a fan 6 of a radiator is attached to the opening 8 to form an engine 4 It is located opposite to.

An air guide tube 9 is provided in the outer case 3 of such a private power generator, and one end 10 of the air guide tube 9 is provided in the outer case 3. The other end 12 is opened at an appropriate position near the engine 4 and the generator 5 while opening to the outside through 11. The air guide tube 9 has, for example, a cylindrical tube shape, and one end 10 is connected to the air supply hole 11 and the other end 12 is positioned so as to open toward the lower portion of the engine 4, for example.

The present invention is configured as described above. Then it becomes as follows. This private power generator is provided with a wind guide tube 9 having one end 10 opened to the outside and the other end 12 opened to an appropriate position near the engine 4 and the generator 5. In this private power generator, when the fan 6 is rotationally driven during use, the inside of the outer case 3 has a negative pressure, and air is first introduced from the air supply port 1 of the outer case 3 to cause the engine 4, An air flow A is formed, which passes through the generator 5 and the like almost entirely and goes to the exhaust port 2. Then, due to the air flow A as described above, the engine 4, the generator 5, etc., which become hot, are temporarily cooled. Now, in this private power generator, air also flows in together with this from the air supply hole 11 of the outer box 3, and through the other end 12 from one end 10 of the air guide tube 9 to the cooling point of the engine 4, the generator 5, etc. After hitting (the lower part of the engine 4 in the illustrated example), the air flow B toward the exhaust port 2 is also formed. Then, it becomes the following first and second.

First, due to the air flow B through the air guide tube 9 as described above, a locally high temperature-required cooling place such as the engine 4 and the generator 5, particularly the above-mentioned overall air It becomes difficult to hit the flow A 2 smoothly, and the portion requiring cooling (the lower part of the engine 4 in the illustrated example) that easily separates from the air flow A can be cooled efficiently, directly, and reliably. Secondly, this air guide tube 9 has only one end 10 to be connected to the air supply hole 11 of the outer casing 3 and the other end 12 to be positioned so as to face the engine 4, the generator 5 or the like where cooling is required. It is possible to appropriately and freely cool the cooling required portion by the air flow B. In this way, the cooling of the cooling-needed portion is realized easily and easily by the air guide tube 9 without affecting the power generation capacity of the private power generator.

In this type of private power generator, as described above, glass wool, sponge or the like is attached to the inner surface of the outer box 3 so that noise from the internal engine 4 and the generator 5 should be external. Care is taken to prevent leakage. Therefore, it is advisable to consider the soundproof surface of the air guide tube 9 as well, for example, by making it meander instead of passing it in a substantially straight line as shown in the drawing, or by adopting a conventionally known sound deadening structure inside.

[0014]

[Effect of the device]

 As described above, the private power generator according to the present invention exhibits the following effects by providing the air guide tube with one end and the other end arranged in a predetermined manner. Firstly, it becomes possible to locally cool the cooling-needed area. In other words, it is possible to efficiently, directly, and reliably cool the cooling points such as the engine and generator where the temperature is locally high. Therefore, for example, the part of the engine under which the engine oil flows can be surely cooled, and the engine oil can be prevented from exceeding a predetermined operating temperature, and can be always used without any problem.

Second, and yet this can be achieved easily and easily without affecting the power generation capacity. That is, unlike the conventional example of this kind, a simple structure in which an air guide tube is provided without adding a dedicated fan can be easily realized with excellent cost. Furthermore, unlike the conventional example of this kind, it can be realized without lowering the rotation of the engine and without lowering the power generation capacity as an in-house power generator. Thus, the effects of the present invention are remarkably large, such as the problems existing in this type of conventional example are eliminated.
