The exhaust muffler device includes an upper arc-shaped rain-proof sound-absorbing roof 8, an exhaust muffler chamber 12 and an exhaust window. 13 and the exhaust muffler sheet 7 with shunt effect, and the exhaust muffler sheet 7 is plate arrangement.

Example 2

As shown in Fig. 2, the anechoic room of the air-conditioning unit includes an air-conditioning unit 9, an exhaust fan 10, a damping pad 11 and an anechoic room body 5 located on the periphery of the air-conditioning unit 9, and the lower end of the anechoic room body 5 is provided with a foundation base 1. On the upper part of the foundation base 1, an air inlet muffler 2 and a sound insulation and daylighting window 4 are arranged in sequence. In the air inlet muffler 2, a wave-type sound-absorbing sheet 3 is arranged. The sound room body 5 is a bent structure, and there is an exhaust muffler device on the upper part of the muffler room body 5. The exhaust muffler device includes a muffler wall 6, an exhaust muffler sheet 7, and a T-shaped rain-proof sound-absorbing roof. 8.
