Abstract

PURPOSE:To make a generator unit compact as a whole and to improve the stability and transportability by pacing an engine, a generator, and a fuel tank in parallel on a structure and installing an engine muffler above the generator. CONSTITUTION:A fuel tank 3, an engine 4, and a generator 5 are placed in parallel on a structure (base plate) 1. A muffler 12 for the engine is installed above the generator 5. By placing individual element lengthwise like this, the unit can be made narrow and compact. Since the position of the center of gravity is lowered at the same time, the stability and transportability of the generator unit can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small-sized power generator integrally provided with an engine and a generator driven by the engine.

Since this type of generator is mainly used in places where it is impossible to extract electricity from power lines, the most important thing is that it can be easily carried to any place, and therefore, it is important to be able to easily transport it to any place. There is a strong demand for a four-contact system.

The present invention was made based on these circumstances, and
The purpose is to install the engine, engine, engine, and fuel tank, which have a large weight, in parallel on the structure, and to place the engine silencer above the single-engine engine. The objective is to provide a small-sized motor generator that not only has a more compact design but also lowers the center of gravity and improves stability and transportability.

The present invention will be explained below based on an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a bottom plate as a structure made of a press-formed product such as a steel plate, and has a substantially rectangular shape. As shown in FIGS. 1 and 2, a fuel tank 3, an engine 4, and a generator 5 are arranged in this order from the right side to the left side on the bottom plate 1. An air cleaner 6 is arranged above the engine 4, and outside air taken in through the air cleaner 6 is supplied to an intake port 9 of the engine 4 through a carburetor 7 and an intake manifold 8.

On the other hand, an exhaust pipe 1 extending upwards from the generator 5 is connected to the exhaust gas of the engine 4, and a silencer 512 made of a steel plate is welded to the tip of the exhaust pipe 1. ing. The muffler 12 has a substantially box-like shape with a large capacity expansion chamber 12a inside, and has a large volume considering its size. The muffler 12 is placed just above the generator 5, and is located on the opposite side of the fuel tank 3 across the ennon 4. The periphery of the muffler 12 is covered with a Grotector 13, and a heat insulating material 14 such as glass wool is adhered to the entire outer peripheral surface of the Grotector 13.

Various parts such as the engine 4, the generator 5, and the silencer 12 arranged in this way are placed between the front cover 15 and the rear cover 16.
covered by. These double force bars 15 and 16 are made of aluminum casting, for example, and are divided into 1c2 parts in the vertical direction and are removably abutted against each other.

Note that reference numeral 17 is a handle, which is rotatably attached to the front cover 15.

However, according to the power generation device having such a configuration, the bottom plate 1
Main parts such as the engine 4 and generator 5, which are heavy, and the fuel tank 3 for storing fuel are installed side by side on the top, and although the shape is relatively large, it is made of steel plate and has a large expansion chamber 12h, making it lightweight and noise-reducing. Place parts such as the air cleaner 12 and the similarly large but lightweight air cleaner 6 above the generator 5 and the engine.
This position lowers the center of gravity of the entire device, increasing stability.

Moreover, since the engine 4, generator 5, and fuel tank 3 are arranged along the longitudinal direction of the bottom plate 1, the entire device can be made narrow and compact, and when carried by gripping the handle 17, it is difficult to carry the device. It's not hard to hit, and you can easily carry it around. In addition, it has the advantage that it does not require a large space for storage. In this embodiment, the silencer 12, which becomes hot during use, is placed above the generator 5, and the fuel tank 3 is placed above the engine 4. Since the silencer 12 is placed on the opposite side of the fuel tank 3,
By moving the fuel supply system away from the fuel supply system, such as the carburetor 7, etc., it is possible to prevent abnormal temperature rise of the fuel supply system.

In the above-described embodiment, a four-stroke engine was used as the engine, but a two-stroke engine may also be used.

Further, the motor generator according to the present invention is not limited to covering various component parts such as the engine and the generator with a cover, and these parts may be exposed to the outside as they are.

The present invention described in detail above has a structure in which an engine, a generator, and a fuel tank are arranged side by side on a structure, and a silencer for the engine, which is lightweight despite its large volume, is arranged above the generator. The center of gravity is lower, increasing stability. At the same time, the overall width of the device is narrow and compact, making it easy to carry and not requiring a large space for storage.
