Abstract

The utility model provides an engine-driven type generator. The engine-driven type generator comprises a box, wherein the box is used for accommodating an engine and a generator which is driven by the engine; a gas inlet cover and a gas exhaust cover are arranged in the box; the gas inlet cover is used for covering a gas inlet side part of the engine; the gas exhaust cover is used for covering a gas exhaust side part of the engine; a gas exhaust silencer which is arranged on a gas exhaust pipeline of the engine is arranged between the engine and the gas exhaust cover. According to the engine-driven type generator, the inside gas exhaust cover and the outside box form a double-layer sound-proof structure. Therefore, noise generated by the gas exhaust silencer can be effectively suppressed.

Description

Engine generator

Technical field

The utility model relates to a kind of engine generator, relates in particular to the acoustic construction of engine generator.

Background technique

Engine generator is also referred to as engine type motor, is to be a kind ofly contained in the equipment in same casing by motor with by this engine-driven generator.The noise that this equipment produces is in use larger, therefore needs to design the good acoustic construction of a kind of soundproof effect.

Model utility content

The utility model proposes in order to address the above problem, and its object is to provide a kind of acoustic construction that can effectively suppress the engine generator of noise.

For achieving the above object, according to the utility model one embodiment's engine generator, in casing, hold motor and by described engine-driven generator, and, the exhausting hood in described casing with the air inlet cover cap of the air inlet side part that covers described motor and the exhaust side part of the described motor of covering, the exhaust silencer being arranged on described waste pipe road is arranged between described motor and described exhausting hood.

Preferably, the surface of the surface area maximum of described exhaust silencer is towards described exhausting hood.

Preferably, the rear cover of described generator is directly connected with described exhausting hood.

According to the utility model, the exhausting hood of inner side and the casing in outside form double-deck acoustic construction, can effectively suppress thus the noise being produced by exhaust silencer.And the surface of the surface area maximum of exhaust silencer easily vibrates, therefore make this surface towards exhausting hood, can further suppress thus noise.And, be connected with exhausting hood by the cover cap that makes generator, can further suppress thus noise.

Accompanying drawing explanation

Fig. 1 is according to the stereogram of the utility model embodiment's engine generator.

Fig. 2 is according to the stereogram of the generator set zoarium in the utility model embodiment's engine generator.

Fig. 3 be observe from another angle according to the stereogram of the generator set zoarium the utility model embodiment's engine generator.

Embodiment

Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.

As shown in Figure 1, according to the utility model one embodiment's engine generator, have for holding motor and the casing by engine-driven generator.This casing can be combined by front cover 11, rear end cover 12, housing 13.And housing 13 can be assembled by left side housing and right side housing again.This casing forms the outward appearance of engine generator, plays the effect of supporting and protecting inner member.

Be provided with generator set zoarium at box house.As shown in Figures 2 and 3, generator set zoarium 20 comprises air inlet cover cap 22, exhausting hood 23 and rear cover 24.Air inlet cover cap 22, exhausting hood 23 and rear cover 24 form motor and the containing space by engine-driven generator jointly, play the effect that suppresses motor and generator noise and guiding cooling blast simultaneously.Air inlet cover cap 22 and exhausting hood 23 surround motor from both sides.Wherein, the air inlet side part of air inlet cover cap 22 covering engines, the exhaust side part of exhausting hood 23 covering engines.

In engine generator, be provided with exhaust silencer.This exhaust silencer is arranged on waste pipe road, the noise that the gas of combustion of discharging for reducing motor produces.But exhaust silencer also becomes a part that produces maximum noises in whole engine generator.

For this reason, in embodiment of the present utility model, as shown in Figure 2, exhaust silencer 25 is arranged between motor and exhausting hood 23.Thus, the noise that exhaust silencer 25 produces is wanted to be successively afterwards just delivered to outside by exhausting hood 23 and casing, therefore can effectively suppress the noise being produced by exhaust silencer 25.

Further, the surfaces A of the surface area maximum of exhaust silencer 25 is easily vibrated, and therefore makes this surface towards exhausting hood 23, can further suppress thus noise.

Further, the rear cover 24 of generator is directly connected with exhausting hood 23, can further suppresses thus noise.

In addition, the undeclared symbol 26 in Fig. 2 is the outlet pipe of exhaust silencer 25, and it is connected with the exhaust port on rear end cover 12.

The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.

Claims

1. an engine generator, in casing, hold motor and by described engine-driven generator, it is characterized in that, the exhausting hood in described casing with the air inlet cover cap of the air inlet side part that covers described motor and the exhaust side part of the described motor of covering, the exhaust silencer being arranged on described waste pipe road is arranged between described motor and described exhausting hood.

2. engine generator as claimed in claim 1, is characterized in that, the surface of the surface area maximum of described exhaust silencer is towards described exhausting hood.

3. engine generator as claimed in claim 1 or 2, is characterized in that, the rear cover of described generator is directly connected with described exhausting hood.
