The air outlet structure in the embodiment of the present invention includes a flow guiding wall 100 and an air outlet 200. The side of the air guiding wall 100 adjacent to the air outlet 200 includes a sloped section 101 and a horizontal section 102 extending from the inclined section 101 in a horizontal direction.

According to the air outlet structure in the embodiment of the present invention, since the horizontal section 102 extending in the horizontal direction is added on the basis of the inclined section 101, the air outlet 200 is not reduced under the cooling condition, and the air outlet area is not Will reduce, to ensure the ability of the machine to quickly cool. At the same time, referring to FIG. 7 and FIG. 8 , it can be seen from the comparison of the simulation diagrams that the air outlet airflow in the embodiment of the present invention is substantially horizontal, and the prior art is a downward direction, so the air outlet structure in the embodiment of the present invention is not There will be a cold wind blowing phenomenon, which satisfies the effect of air conditioning, cooling and showering, thus improving the comfort of refrigeration.

In order to further optimize the above-described horizontal section 102, a sound absorbing chamber 103 is also provided. The sound absorbing cavity 103 is a blind hole in the cavity, and the airflow inside the sound absorbing cavity 103 acts as a spring to absorb the energy of the airflow and reduce the turbulent energy of the airflow.

The width L of the sound absorbing chamber 103 satisfies: L ≥ 10 mm, so that the sound absorbing chamber 103 has a sufficient length to absorb the turbulent energy of the air flow, thereby reducing noise generation. The sound absorbing chamber has a longitudinal direction and a width direction, wherein the longitudinal direction is the axial direction of the wall hanging machine, the direction perpendicular to the longitudinal direction is the width direction, and the width is the dimension in the width direction of the sound absorbing cavity.

The depth H of the cavity of the sound absorbing chamber 103 satisfies: 4 mm ≤ H ≤ 20 mm. Of course, the depth of the sound absorbing chamber 103 is not limited to only such a size.

In the process of passing the high-speed airflow of the deflector wall 100 through the sound absorbing cavity 103 by the Helmholtz muffling principle, the energy of the gas is absorbed by the sound absorbing cavity 103, which reduces the turbulence intensity of the outlet airflow, and further reduces the eddy current noise of the outlet airflow, thereby improving The sound quality of the whole machine.

Referring to FIG. 9 and FIG. 10, the turbulent energy of the air outlet in FIG. 9 is significantly lower than the turbulent energy of the air outlet in FIG. 10, and the aperture size is 2.5 mm in the simulation model, and the specific noise reduction effect needs to be based on actual conditions. The aperture size is confirmed. In the embodiment of the present invention, the aperture M of the sound absorbing hole 105 satisfies: 1.5 mm ≤ M ≤ 5 mm. The hole pitch N of the plurality of sound absorbing holes 105 satisfies: 0.5 M ≤ N ≤ 4 M. Being in the above range can eliminate most of the eddy current abnormal noise frequency caused by the air outlet.

The plurality of sound absorbing holes 105 may be arranged regularly or irregularly. As shown in FIGS. 5 and 6, the sound absorbing holes 105 are arranged in a row. In FIG. 5, the adjacent sound absorbing holes 105 in the adjacent rows are aligned with each other. Adjacent sound absorbing holes 105 in adjacent rows in Fig. 6 are alternately arranged.
