[0039] Compared with the prior art, the casing assembly with noise reduction and silencing functions provided by the embodiments of the present utility model has a duct communicating the air inlet 11 with the air outlet 12 inside the casing 1, a sound insulation cover 21 for covering the compressor 3 is arranged in the installation cavity 13 located in the duct, and a sound absorption member 22 is arranged on the inner wall of the sound insulation cover 21. When the compressor 3 is accommodated and installed in the sound insulation cover 21, the sound insulation cover 21 can independently isolate the compressor 3 in the duct, effectively blocking the noise generated during the operation of the compressor 3 from being transmitted to the air outlet 12 through the duct.

[0040] Please refer to Figure 2 , Figure 4 and Figure 7 . In some embodiments, the sound absorption member 22 is a sound absorption layer covered on the inner wall of the sound insulation cover 21. The sound absorption layer can effectively absorb the noise generated during the operation of the compressor 3. Coupled with the sound insulation cover 21 effectively blocking the noise generated during the operation of the compressor 3 from being transmitted to the air outlet 12 through the duct, thereby avoiding the harsh noise generated during the operation of the compressor 3 from being transmitted to the room through the air outlet 12. It can be understood that the sound absorption layer can be, but is not limited to, a sound absorption cotton layer made of sound absorption cotton. For example, the sound absorption layer can also be made of foam plastic sound absorption material.
[0041] Please refer to Figure 1 、 Figure 2 and Figure 8 In some embodiments, the air duct includes a dehumidification chamber 14 for installing the evaporator 4 and the condenser 5 and a air supply chamber 15 for installing the blower 6. The installation chamber 13 is located between the dehumidification chamber 14 and the air supply chamber 15. The dehumidification chamber 14 communicates with the air inlet 11, and the air supply chamber 15 communicates with the air outlet 12. An air inlet passage and a heat dissipation passage are respectively provided on the sound insulation cover 21. The air inlet passage communicates with the dehumidification chamber 14, and the heat dissipation passage communicates with the air supply chamber 15. Since the blower 6 is installed at a position close to the air outlet 12 in the air supply chamber 15, under the action of the blower 6, the indoor air is sequentially transported to the air outlet 12 through the air inlet 11, the dehumidification chamber 14, the air inlet passage, the sound insulation cover 21, the heat dissipation passage and the air supply chamber 15. The air dehumidified and dried by the evaporator 4 and the condenser 5 in the dehumidification chamber 14 can cool the compressor 3 in the sound insulation cover 21 by air cooling during the process of flowing through the sound insulation cover 21, can timely and smoothly take away the heat generated when the compressor 3 works, effectively reduce the temperature of the compressor 3, and thus reduce the temperature and pressure of the gaseous refrigerant circulating inside the compressor 3, which is effectively beneficial to realizing the shock absorption and noise reduction of the compressor 3 pipeline system. At the same time, the heat generated by the compressor 3 can reheat and raise the temperature of the dehumidified air, and the heat generated by the compressor 3 is used to further reduce the relative humidity in the air, which is beneficial to improving the dehumidification efficiency and dehumidification effect of the dehumidifier.
[0042] Please refer to Figure 3 、 Figure 4 and Figure 8 In some embodiments, the heat dissipation passage is composed of a plurality of heat dissipation holes 211. The plurality of heat dissipation holes 211 are provided on the top of the sound insulation cover 21, and the distance between adjacent two heat dissipation holes 211 is equal, which can allow the air carrying heat to pass through the plurality of heat dissipation holes 211 smoothly and timely, and can timely and smoothly take away the heat generated when the compressor 3 works, effectively reducing the temperature of the compressor 3 in the sound insulation cover 21.
[0043] Please refer to Figure 5 、 Figure 6 and Figure 7 In some embodiments, sound absorption, reflection or isolation sound muffling covers 212 are respectively provided on the sound insulation cover 21 at positions corresponding to the respective heat dissipation holes 211, which can block the noise transmitted through the heat dissipation holes 211, and is beneficial to avoiding the harsh noise generated when the compressor 3 operates from being transmitted to the indoor through the air outlet 12.
[0044] Please refer to Figure 6, in some embodiments, an air passing notch 213 communicating with the heat dissipation channel 211 is provided at the bottom of the sound insulation cover 212. While the sound insulation cover 212 blocks the noise propagated through the heat dissipation channel 211, it allows the air carrying heat to smoothly and timely discharge through the plurality of heat dissipation channels 211 and the air passing notch 213, taking into account the effects of sound insulation and noise reduction as well as heat dissipation and temperature reduction.
[0045] Please refer to Figure 3 , in some embodiments, both the air inlet 11 and the air outlet 12 are located on the side of the housing 1, and the setting position of the air outlet 12 is higher than that of the air inlet 11, extending the flow path of the air, which is beneficial to improving the dehumidification effect and playing a role in sound insulation and noise reduction.
[0046] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, both the evaporator 4 and the condenser 5 are in a U-shaped structure or a C-shaped structure. The air supply cavity 15 is located inside the condenser 5, and the air supply cavity 15 is separated between the dehumidification cavity 14 and the installation cavity 13, preventing the heat generated by the condenser 5 from directly transferring heat or thermal radiation to the air in the isolation cover 21 in the installation cavity 13, which is beneficial to reducing the air temperature in the isolation cover 21, thereby avoiding the temperature in the isolation cover 21 being too high and affecting the normal operation of the compressor 3. It should be noted that the isolation cover 21 is located inside the condenser 5.
