吸音し減衰させることにより達成される。[Operation] Since the sound wave has a straight traveling property, it travels straight in the duct. Therefore, a chamber larger than the discharge port is provided in the vicinity of the discharge port, and a sound wave traveling straight in the duct is applied to the wall of the chamber to attenuate the sound. If the chamber is the same as or smaller than the discharge port, the muffling effect is small, so a chamber larger than the discharge port is provided. In addition, by providing a double-structured chamber having an inner wall and an outer wall that are larger than the discharge port, and the inner wall is made of a sound absorbing material with many holes, sound is generated in the air layer between the sound absorbing material and the chamber outer wall. This is achieved by absorbing and damping the sound.

きるだけ大きいチャンバー６を設ける。When the operation of the air conditioner 1 is started in the above structure, the air sent from the blower 3 flows in the duct 4 and a sound is generated. Since the sound wave has a straightness,
Go straight in the duct 4. Therefore, a chamber 6 larger than the discharge port 5 is provided in the vicinity of the discharge port 5, and a sound wave traveling straight in the duct 4 is applied to the wall of the chamber 6 to attenuate the sound in the chamber 6. If the chamber 6 is the same as or smaller than the discharge port 5, the muffling effect is small. Therefore, the chamber 6 as large as possible than the discharge port 5 is provided.

様の消音効果を得ることが出来る。FIGS. 2 and 3 show a second embodiment of the present invention, in which a chamber having a double structure having an inner wall 8 and an outer wall 9 larger than the discharge port 7 is provided, and the inner wall 8 has a large number of holes. It is composed of a bright sound absorbing material. Noise can be reduced by absorbing and damping the sound in the air layer between the sound absorbing material and the outer wall 9 of the chamber. Inner wall 8 and outer wall 9
The gap is 20 mm to 100 mm, and the larger the gap, the more the low frequency noise can be reduced. The sound absorbing material is a punching plate in which a large number of small holes are formed in a metal plate, expanded metal, glass wool, or a resin molded product in which small holes are formed. Further, as shown in FIG. 4, the chamber 10 that is greatly extended to the opposite side of the duct 11 can also obtain the same sound deadening effect.
