4 and a compressor soundproofing material such as a top side soundproofing material (not shown). Therefore, the noise generated in the compressor 1 can be suppressed from leaking to the outside, and an air conditioner with improved noise reduction can be provided. In addition, the first horizontal soundproofing member 11 is configured such that the suction pipe 6 is inserted into the contact portion 24 so as to contact from the front side, and the first gas pipe 5 is inserted into the upper cut portion 21 and the lower cut portion 22. It is fitted from behind. Then, the first horizontal soundproofing material 11 is positioned and fixed in the casing, so that the first horizontal soundproofing material 11 can be prevented from being displaced gradually due to vibration of the compressor 1 or the like.
Therefore, the excellent soundproofing effect provided by providing the first lateral soundproofing material 11 can be always maintained. The first horizontal soundproofing material 1
The insertion front end side of 1 is only brought into contact with the suction pipe 6, and the fitting operation of the first gas pipe 5 is performed at the insertion rear end side with good workability. Therefore, the work of positioning and fixing the first lateral soundproof material 11 can be easily performed.

The first horizontal soundproofing member 11 is formed so that the first gas pipe 5 is sandwiched between the end portions 11a and 11b on the rear end side of the first horizontal soundproofing member. Therefore, the first gas pipe 5 does not easily come off from the upper cutout 21 and the lower cutout 22, and the first lateral soundproofing member 11 is inserted by the vibration of the compressor 1 and moved to the rear end side. Can be reliably prevented. Moreover, since the first lateral soundproofing member 11 has elasticity in a direction intersecting the sheet surface, that is, in a direction sandwiching the first gas pipe 5, the movement can be prevented more reliably. Since the first horizontal soundproofing member 11 can be prevented from being inserted and moving to the rear end side, the first horizontal soundproofing member 11 contacts the front plate of the casing and transmits the vibration of the compressor 1 to the casing. There is no danger that it will happen. Therefore, the excellent quietness of the outdoor unit can be reliably maintained. Further, in the first horizontal soundproofing material 11, the suction pipe 6 is fitted into the insertion hole 23b from the insertion front side through the slit 23a. Therefore, the positioning and fixing of the first horizontal soundproofing material 11 is further ensured, and the suction pipe 6 is fitted into the insertion hole 23b through the slit 23a with the insertion operation of the first horizontal soundproofing material 11. Therefore, the workability is not reduced.

Further, in the outdoor unit, the first lateral soundproofing material 11
Are positioned and fixed by refrigerant pipes of a first gas pipe 5 and a suction pipe 6. Therefore, it is possible to prevent the vibration of the compressor 1 from being transmitted to the casing via the first lateral soundproofing member 11. That is, the vibration of the compressor 1 is transmitted to the first gas pipe 5 and the suction pipe 6 via the first horizontal soundproof material 11, but these refrigerant pipes are originally connected to the compressor 1 and the vibration is already transmitted. This is because the quietness is not particularly impaired by this. That is, the vibration of the compressor 1 transmitted to the refrigerant pipe via the first horizontal soundproofing member 11 can be reliably absorbed by the vibration-proof structure conventionally provided to the refrigerant pipe. Therefore, the first lateral soundproofing member 11 can be positioned and fixed without deteriorating good noise reduction.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be implemented with various modifications within the scope of the present invention. In the above, the first horizontal soundproof material 11 is positioned and fixed by the refrigerant pipes of the first gas pipe 5 and the suction pipe 6. However, the present invention is not limited to such refrigerant pipes, and various structures such as columns in the casing may be used. The first horizontal soundproof material 11 may be positioned and fixed. In this case, by selecting a member that transmits as little vibration as possible to the casing, noise can be reduced. Further, in the above, it is arranged so as to extend up and down, and
In the above description, the compressor soundproofing material to be inserted in the lateral direction) and the compressor soundproofing material arranged to extend in the lateral direction and the compressor soundproofing material to be inserted from the side and mounted in the casing are described above. The position may be fixed by the same configuration as described above. Since these compressor soundproofing materials are also likely to be displaced by the vibration of the compressor 1, the excellent effects can be obtained by applying the present invention as described above. Further, in the above description, the first lateral soundproofing material 11
On the rear end side of the insertion, semi-circular cutouts 21 and 22 corresponding to the outer shape of the first gas pipe 5 were provided to function as cutouts. It may be such that only a cut is provided. In the above description, the present invention is applied to an outdoor unit of a separation type air conditioner, but the present invention can be applied to, for example, an integrated air conditioner.
