Abstract

Reduce noises emitted from inlet and outlet of cooling air of a soundproof enclosed type generator. An inlet 20 and an outlet 26 of the cooling air are provided to the front and rear of a chassis 2, respectively. An air supply duct 8 is detachably mounted to the inlet 20, and an exhaust duct 9 is detachably mounted to the outlet 26. An air taking-in opening 8a facing downward is provided to the air supply duct 8 which guides the air towards horizontally opened inlet 20. The exhaust duct 9 is equipped with wall surface and a straightening vane 27 at a position opposed to the cooling air discharged from the outlet 26 to change the cooling air flow in complicated fashion to discharge it outside. Sound-absorption materials are pasted to the interior surface of the air supply duct 8 and the exhaust duct 9.

Description

technical field

[0001] The invention relates to a sound-proof and airtight generator, in particular to a sound-proof and airtight generator suitable for improving the sound-proof performance. Background technique

[0002] In order to suppress the running noise and protect the generator (including the engine, generator body, muffler, and electrical installation control device) from dust and water, the soundproof and sealed generator is formed into a structure that surrounds the generator with a box. In the sound-proof and airtight generator, the generator is housed in a sealed box, and the box is provided with a cooling air inlet and a cooling air outlet for cooling the generator. Therefore, there is a disadvantage that the operation sound of the generator leaks from these cooling air inlets and cooling air outlets. Therefore, sound insulation treatment is taken to suppress leakage of running sound to the outside. For example, in the sound insulation structure of the power ...

Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail with reference to the drawings. figure 2 It is a front perspective view of a sound-proof sealed generator according to an embodiment of the present invention, image 3 It is a three-dimensional view of its back. exist figure 2 , image 3 Among them, the inside of the casing 2 of the generator 1 accommodates a generator main body (described later) driven by an engine. The box body 2 is airtight except for the cooling air inlet and the cooling air outlet. An electrical installation room (described later) is provided at the front of the housing 2 , and an operation panel 7 including an output terminal 4 , an operation unit 5 and a display unit 6 is provided on the front surface of the electrical installation room. A cooling air inlet is provided below the operation panel 7 , but the cooling air inlet is covered with an air inlet channel 8 , so it is not shown in FIG. 1 . The air intake duct 8 draws outside...
