た。 In the conventional soundproof package structure of such an engine-driven heat pump, the engine intake pipe intake port was configured to protrude outside the box-shaped casing. This has the drawback that the intake noise is emitted into the atmosphere, making it impossible to obtain sufficient soundproofing effects even though the engine and compressor are constructed in a soundproof package.

ある事を特徴とする。 In the soundproof package structure of the engine-driven heat pump according to the present invention, the intake pipe of the engine is opened to the latter compartment, and the outer wall of the latter compartment has an area larger than the intake area of the intake port. The outside air intake port is characterized in that the latter compartment serves as an external muffling chamber for intake noise generated with intake air from the intake pipe intake port.

ンパクトなものにできる利点もある。 Therefore, according to the present invention, the noise problem caused by intake noise can be solved by simple and inexpensive structural modification in which the latter compartment is also used as an intake silencing chamber, without providing a special intake silencing chamber. I've reached it. Moreover, since the intake pipe does not protrude from the box-like casing, there is an advantage that the box-like casing can have a smooth outer surface, that is, it can be made compact, which is advantageous for the overall equipment.

Since the release to the outside is suppressed, and the area of the outside air intake port 16 is larger than the area of the intake port 13a, the flow velocity of the air passing through the outside air intake port 16 is reduced to the same level as that of the intake port 13a.
Since the flow rate of the air passing through a is slow, the sound generated by the air passing through the outside air intake port 16 is very small.
