Adjustable length and automatic adaptation of system pressure to muffler and air conditioner

Abstract

The invention discloses a silencer with adjustable length and self-adapting system pressure. The silencer with the adjustable length and the self-adapting system pressure comprises an air inlet, an air outlet, a middle barrel, a left barrel, a right barrel, a flow guide plate and two elastic pieces. The left barrel sleeves and is movably connected with the left end of the middle barrel and moves relative to the middle barrel in a left and right adjusting mode; the air inlet is located on the left barrel; the right barrel sleeves and is movably connected with the right end of the middle barreland moves relative to the middle barrel in a left and right adjusting mode; the air outlet is located on the right barrel; the flow guide plate is arranged in an inner cavity of the middle barrel in amatched mode and correspondingly communicates with the air inlet and the air outlet; and the two elastic pieces are correspondingly connected with the two sides of the flow guide plate and the middlebarrel. According to the silencer with the adjustable length and the self-adapting system pressure, the length of barrels can be adjusted, meanwhile, the self-adapting system pressure is realized, and finally the final effect of stably eliminating noise is realized; and the invention further provides an air conditioner of the silencer with the adjustable length and the self-adapting system pressure.

Description

technical field [0001] The invention relates to a muffler, in particular to a muffler with adjustable length and automatic system pressure adaptation; and an air conditioner with the adjustable length and automatic system pressure adaptation muffler. Background technique [0002] During the operation of the air conditioner, as the indoor and outdoor ambient temperature changes, the operating load of the air conditioner also changes, the system refrigerant pressure is also different, and the peak frequency of the generated noise is also different. The muffler is widely used as a device commonly used to solve the sound transmission of the air conditioner external unit. [0003] The formation of the sound transmitted by the compressor is closely related to the environment in which the system is used, and the peak frequencies of the noise generated by different environments are also different. In practice, there will be problems such as unsatisfactory or even poor noise reducti...

Problems solved by technology

[0007] The patent No. CN108626874A discloses a noise reduction device, a control method of the noise reduction device and an air conditioner. There are a first pipe body and a second pipe body inside the housing, and the second pipe body has a passage for the medium to pass through. The flow channel, the length of the flow channel is adjustable, although this noise reduction device solves the problem of the air conditioner muffler in the prior art, it cannot meet the problem of noise reduction when the system frequency is different
