Problems solved by technology

[0004] In the process of realizing the above-mentioned air duct machine, the inventor found that there are at least the following problems in the prior art: since the air outlet 023 of the volute 021 is opposite to the evaporator 03, when the wind blows out from the air outlet 023 of the volute 021, especially The wind speed at the tangent line of the outer edge of the impeller 022 is very fast and has a certain static pressure. When the wind blows directly to the evaporator 03 and passes through the fins, the fins of the evaporator 03 are easily blown under the action of high wind pressure and high wind speed. Abnormal vibrations are generated, resulting in abnormal sounds, which degrades the user experience

Abstract

The invention discloses a wind pipe machine and relates to the technical field of air conditioners. The wind pipe machine is invented for solving the problem that in the prior art, when a wind pipe machine works, fins of an evaporator produce abnormal sounds. The wind pipe machine comprises a machine shell. A centrifugal fan and an evaporator are arranged in the machine shell. The centrifugal fan comprises a volute and an impeller arranged in the volute. An air outlet of the volute is opposite to the evaporator. A flow guide bar is arranged at the position of the air outlet of the volute, and the extending direction of the flow guide bar is parallel to the rotating center line of the impeller. At least one part of the flow guide bar is located on the air outlet route tangent to the edge of the impeller. The wind pipe machine can be used for air conditioner indoor units.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air duct machine. Background technique [0002] The air duct machine is a new model developed in response to the diverse needs of the market and the changes in the overall decoration space. It is suitable for installation and maintenance of small width occasions, especially for small-sized families. Now users have higher and higher requirements for reducing their noise. Because the household ceiling-buried air duct machine is installed in the bedroom, it is even more necessary to effectively control the noise level of the air duct machine, and not allow abnormal noise, so as to achieve comprehensive silence. Effect. [0003] An existing air duct machine is as figure 1 The structure shown includes: a casing 01, a centrifugal fan 02 and an evaporator 03 are arranged in the casing 01, the centrifugal fan 02 includes a volute 021 and an impeller 022 arranged in the volu...
