The following describes the air outlet cover 100 and the outdoor unit of the air conditioner according to the embodiment of the invention with reference to fig. 1 to 7.
As shown in fig. 1, according to the air outlet cover 100 of the embodiment of the present invention, the air outlet cover 100 includes: frame 10 and ribs 20.
Specifically, as shown in fig. 1, the frame body 10 includes two first side walls 110 arranged in parallel and two second side walls 120 arranged in parallel, each first side wall 110 intersecting with two second side walls 120. For example, the frame 10 may have a square, rectangular, or parallelogram shape. Therefore, the frame 10 is convenient to process and manufacture, so that the production efficiency of the air outlet mesh enclosure 100 can be improved, and the production cost of the air outlet mesh enclosure 100 is reduced. Moreover, the air outlet area of the air outlet net cover 100 is improved, so that the air inlet volume of the air outlet net cover 100 is increased.
As shown in fig. 1, a first grating area S1 and a second grating area S2 are distributed in the frame 10, and a plurality of ribs 20 are arranged in the first grating area S1 and the second grating area S2 at intervals. From this, through setting up rib 20, can improve the homogeneity and the uniformity of air-out screen panel 100. At least one corner of the frame body 10 is provided with the first grill section S1, that is, the first grill section S1 may be provided at one, two, three or four corners of the frame body 10. Wherein each rib 20 in the first grating section S1 extends in a direction parallel to the reference line with the diagonal line passing through the first grating section S1 as the reference line. It can be understood that, the rib 20 of the first grid area S1 at the corner extends along the direction parallel to the reference line, so that the interference of the rib 20 to the air outlet flow can be reduced, the rib 20 of the air outlet mesh enclosure 100 is more adaptive to the flow of the air flow, and the air outlet effect of the air outlet mesh enclosure 100 is improved.
According to the air outlet mesh enclosure 100 of the embodiment of the invention, the frame body 10 of the air outlet mesh enclosure 100 is provided with the two parallel first side walls 110 and the two parallel second side walls 120, so that the processing and manufacturing of the frame body 10 are facilitated, and the air output of the air outlet mesh enclosure 100 is favorably increased. Moreover, the rib 20 at the corner of the frame 10 is arranged along the diagonal direction parallel to the first grid area S1, so that the interference of the rib 20 on the air outlet flow can be reduced, and the air outlet effect of the air outlet net cover 100 is improved.
According to some embodiments of the present invention, as shown in fig. 1, each corner of the frame body 10 may be provided with a first grating area S1, and a plurality of second grating areas S2, each second grating area S2 being provided between adjacent first grating areas S1. Therefore, the uniformity and comfort of the air outlet net cover 100 can be improved. For example, four corners of the frame body 10 may be provided with first grating regions S1, and a second grating region S2 is provided between two adjacent first grating regions S1. Therefore, the air outlet net cover 100 can be symmetrically and uniformly arranged, and the uniformity and the comfort of air outlet of the air outlet net cover 100 are improved.
In some embodiments of the present invention, as shown in FIG. 1, the ribs 20 in each second grill area S2 extend perpendicular to the first sidewall 110 or the second sidewall 120 to which they are attached. Therefore, the ribs 20 are fixedly connected conveniently, and the processing efficiency and assembly of the air outlet net cover 100 can be improved.
According to some embodiments of the present invention, both ends of each first sidewall 110 may be connected to the two second sidewalls 120 by circular arc segments 130. This can improve the appearance of the outlet cover 100. Moreover, the material consumption of the air outlet mesh enclosure 100 can be saved, and the production cost of the air outlet mesh enclosure 100 is reduced. As shown in fig. 4, the four corners of the frame body 10 are provided with circular arc sections 130, that is, the first side wall 110 and the second side wall 120 are connected by the circular arc sections 130. In addition, by providing the circular arc section 130, the partition layout design of the first grating area S1 and the second grating area S2 is facilitated.
In some embodiments of the invention, as shown in FIGS. 2-5, the inner end surface of the rib 20 is configured as a wavy end surface extending along the length of the rib 20. Therefore, the air flow flowing out of the air outlet mesh enclosure 100 has different frequencies, and the air flow of the air outlet mesh enclosure 100 is prevented from generating same-frequency noise, so that the air outlet noise of the air outlet mesh enclosure 100 can be reduced.
According to some embodiments of the invention, as shown in fig. 3, the distance between the peaks and valleys of the wavy end surface in a direction parallel to the height of the rib 20 is h1, and the maximum height of the rib 20 is h2, satisfying: h1 is more than or equal to h2/3 and more than or equal to h 2/2. It will be appreciated that providing a peak-to-valley distance h1 that is too large reduces the structural strength of the rib 20; too small a distance between the peaks and valleys will affect the noise reduction of the ribs 20. Experiments prove that when h2/3 is not less than h1 is not less than h2/2, the structural strength of the ribs 20 can be ensured, and the air outlet noise of the air outlet net cover 100 can be effectively reduced.
In some embodiments of the present invention, as shown in fig. 3 and 4, the valley position of one rib 20 of the two adjacent ribs 20 is disposed opposite to the peak position of the other rib 20. Therefore, the air flows flowing out of the adjacent ribs 20 have different frequencies, so that the air outlet noise of the air outlet net cover 100 can be further reduced.
According to some embodiments of the present invention, as shown in fig. 2 and 3, the ribs 20 have a wavelength L1 that satisfies: l1 is more than or equal to 20mm and less than or equal to 60 mm. It should be noted that, the wavelength of the rib 20 is too long, which affects the noise reduction effect of the rib 20; the too short wavelength of the rib 20 affects the uniformity and consistency of the air outlet net cover 100. Through experimental verification, when L1 is larger than or equal to 20mm and smaller than or equal to 60mm, the noise of the air outlet net cover 100 can be effectively reduced, and the improvement of the air outlet uniformity and comfort of the air outlet net cover 100 is facilitated.
In some embodiments of the present invention, as shown in fig. 6, the air outlet cover 100 may further include: many annular strengthening ribs 30, many strengthening ribs 30 are located the radial inboard of framework 10, and many strengthening ribs 30 set up along the radial direction interval of framework 10, and strengthening rib 30 is connected with rib 20. From this, can improve the structural strength of air outlet net cover 100 through setting up strengthening rib 30, moreover, can improve the air-out homogeneity of air outlet net cover 100.

Moreover, the ribs 20 at the corners of the frame 10 are arranged along the diagonal direction parallel to the first grid area S1 in the form of the interval distribution of the ribs 20, so that the interference of the ribs 20 on the outlet airflow can be reduced, and the outlet effect of the outdoor unit of the air conditioner is improved.
