DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The utility model provides an air conditioner 100 , which can reduce the noise generated by the fan assembly 30 by rectifying the airflow of the air outlet 12 through the rectifying plate 40 , thereby improving the quality of the air conditioner 100 .

[0029] Reference Figures 1 to 6 According to the air conditioner 100 in the embodiment of the present utility model, the air conditioner 100 includes a cabinet 10, a heat exchanger 20, a fan assembly 30 and a rectifier plate 40.

[0030] Among them, the cabinet 10 has an air flow channel 11 and an air outlet 12 connected to the air flow channel 11, the heat exchanger 20 is arranged in the air flow channel 11, and is used for heat exchange with the air flow in the air flow channel 11, the fan assembly 30 is used to drive the air flow in the air flow channel 11 to pass through the heat exchanger 20, the rectifying plate 40 is arranged at the air outlet 12, and has a hollow part 44 for air flow to pass through and rectify the air flow; such an arrangement can reduce the noise generated by the fan assembly 30 in the air conditioner 100 and improve the quality of the air conditioner 100.

[0031] Specifically, when the air conditioner 100 is running, the fan assembly 30 can drive the air flow in the air flow channel 11 to flow through the heat exchanger 20, and the heat exchanger 20 can exchange heat with the air flow in the air flow channel 11 to heat and cool the air flow passing through itself, and the air outlet 12 of the air flow channel 11 can be used as the inlet of the air flow channel 11 or the outlet of the air flow channel 11 to facilitate the air flow to pass through the cabinet 10; in this process, due to the high speed of the fan assembly 30, the noise generated when the air flow passes through the air conditioner 100 increases, and at this time, A rectifying plate 40 is provided at the air outlet 12 of the air flow channel 11, and the rectifying plate 40 can be used to sort out the airflow passing through the air outlet 12 to reduce the airflow noise generated by the fan assembly 30; more specifically, the rectifying plate 40 has a hollow portion 44, which can be suitable for the airflow to pass through, and when the airflow passes through the hollow portion 44, the airflow is rectified. In other words, the disordered airflow enters from one side of the rectifying plate 40, and then is discharged from the other side of the rectifying plate 40 to form a uniformly flowing airflow, so as to reduce the airflow noise generated by the fan assembly 30.

[0032] In addition, the fan assembly 30 can be arranged upstream of the rectifying plate 40, or the fan assembly 30 can be arranged downstream of the rectifying plate 40 to drive the airflow through the heat exchanger 20. The fan assembly 30 can be a backward centrifugal fan, which has a higher speed and higher efficiency and can meet the use requirements of the air conditioner 100. However, since the speed of the backward centrifugal fan is higher, a higher airflow noise is generated at the air outlet 12, so it is necessary to rectify the airflow at the air outlet 12 through the rectifying plate 40 to reduce the noise of the fan assembly 30.

[0033] Therefore, according to the air conditioner 100 in the embodiment of the present utility model, the airflow of the air outlet 12 is rectified by the rectifying plate 40 , so that the noise generated by the fan assembly 30 can be reduced, thereby improving the quality of the air conditioner 100 .

[0034] Reference Figures 1 to 6 In some embodiments of the utility model, the air outlet 12 is arranged downstream of the heat exchanger 20, and the fan assembly 30 is used to drive the air flow passing through the heat exchanger 20 to flow to the rectifier plate 40; it can be understood that the air outlet 12 serves as the outlet of the air flow channel 11. When the air conditioner 100 is running, the fan assembly 30 drives the air flow in the air flow channel 11, and due to the high rotation speed of the fan assembly 30, the air outlet 12 of the air flow channel 11 generates a large noise. Therefore, the rectifier plate 40 can be set at the air outlet 12 of the air flow channel 11. In this way, when the air flow passes through the air outlet 12, it can be rectified by the rectifier plate 40, so that the air flow is transformed from disordered flow to uniform flow, thereby reducing the noise of the air conditioner 100.

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments of the utility model, the fan assembly 30 is arranged between the heat exchanger 20 and the rectifier plate 40. In other words, the fan assembly 30 can be arranged in the air flow channel 11; when working, the air flow passing through the heat exchanger 20 can be driven to flow to the rectifier plate 40, and the air outlet 12 of the air flow channel 11 can be used as the whole air outlet 12 of the air conditioner 100; in this way, the integration of the air conditioner 100 can be improved.

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments of the utility model, the cabinet 10 extends in the up-down direction, the air outlet 12 is arranged at the top of the cabinet 10, and the heat exchanger 20, the fan assembly 30 and the rectifier plate 40 are arranged in sequence from bottom to top; in this way, the air outlet of the air conditioner 100 can be facilitated to improve the user experience.

[0037] In detail, the air flow channel 11 can extend in the up and down directions, and the air flow direction can be the same as the bottom-up direction; when working, the fan assembly 30 can drive the air flow passing through the heat exchanger 20 to flow to the rectifier plate 40, so that the air flow passes through the heat exchanger 20, the fan assembly 30 and the rectifier plate 40 in sequence and is discharged from the top of the cabinet 10. Compared with the case where the air outlet 12 is set at the bottom of the cabinet 10, the top setting of the air outlet 12 is convenient for air outlet, and can avoid the air outlet 12 from blowing directly toward the user located on the side of the cabinet 10, thereby improving the user experience.

[0038] Reference Figures 1 to 6 In some embodiments of the utility model, the rectifying plate 40 includes a plurality of rectifying strips, which are staggered and connected to form a grid shape, and separate a plurality of hollow parts 44; in this way, when the airflow passes through the rectifying plate 40, the disorderly flowing airflow is separated by the plurality of rectifying strips into a plurality of uniformly flowing airflows, and the airflow passes through the plurality of hollow parts 44 separated by the plurality of rectifying strips, thereby reducing the noise generated by the fan assembly 30 and improving the quality of the air conditioner 100.

When the air flow passes through the air outlet 12, the air flow can be separated by the plurality of first straightening strips 41, so that the disordered air flow is transformed into a plurality of uniformly flowing air flows, so as to reduce the noise generated by the fan assembly 30.

[0040] Further, refer to Figure 3 and Figure 6 In some embodiments of the utility model, the plurality of straightening bars further include a plurality of second straightening bars 42, the plurality of second straightening bars 42 are arranged at intervals along the second direction, the second straightening bars 42 are staggeredly connected with the first straightening bars 41, the second direction is perpendicular to the airflow direction, and has an angle with the first direction; in this way, the noise generated by the fan assembly 30 is reduced and the quality of the air conditioner 100 is improved by cooperating with the second straightening bars 42 and the first straightening bars 41.

[0041] In detail, when the air conditioner 100 is working, the fan assembly 30 drives the airflow passing through the heat exchanger 20 to flow to the air outlet 12 of the air flow channel 11. At this time, the rectifying plate 40 arranged at the air outlet 12 can sort the airflow; wherein the rectifying plate 40 includes a plurality of first rectifying bars 41 and a plurality of second rectifying bars 42, wherein the plurality of first rectifying bars 41 are arranged at intervals along the first direction, and the plurality of second rectifying bars 42 are arranged at intervals along the second direction, and the plurality of first rectifying bars 41 are respectively connected to the plurality of second rectifying bars 42 in an interlaced manner, and the first rectifying bars 41 are connected to the plurality of second rectifying bars 42 in an interlaced manner.

[0042] Furthermore, refer to Figure 3 In some embodiments of the present invention, the first direction is perpendicular to the second direction, that is, the angle between the first direction and the second direction is 90°, so that the projections of the plurality of hollow portions 44 in the air flow direction of the air outlet 12 are all square, so that the air flow passing through the rectifying plate 40 can be divided into a plurality of uniform air flows, so as to further reduce the noise generated by the fan assembly 30.

[0043] Reference Figure 6 In some other embodiments of the utility model, the plurality of rectifying bars further include a plurality of third rectifying bars 43, the plurality of third rectifying bars 43 are connected to the middle area of ​​the rectifying plate 40, and extend divergently toward the periphery of the rectifying plate 40, the first rectifying bar 41 and the second rectifying bar 42 are connected to the third rectifying bar 43; so as to better reduce the noise generated by the fan assembly 30 and improve the quality of the air conditioner 100.

[0044] In detail, one end of the plurality of third straightening bars 43 is connected to the middle area of ​​the straightening plate 40, and the other end extends toward the periphery of the straightening plate 40, thereby forming a divergent shape; wherein, the plurality of third straightening bars 43 separate multiple areas, and the first straightening bar 41 and the second straightening bar 42 may be respectively provided in the multiple areas, and the third straightening bar 43 is respectively connected to the first straightening bar 41 and the second straightening bar 42, so that when the airflow passes through the straightening plate 40, it can be straightened into multiple uniform airflows by the first straightening bar 41, the second straightening bar 42 and the third straightening bar 43, so as to reduce the noise generated by the fan assembly 30. And in the structure of the straightening plate 40, the plurality of the aforementioned areas surround the center of the straightening plate 40, so that the airflow can be distributed more evenly in the external environment through the straightening plate 40, so as to better reduce the airflow noise generated by the fan assembly 30.

[0045] In some embodiments of the present invention, the area A1 of the hollow portion 44 and the area A2 of the rectifying plate 40, wherein the ratio of A1 to A2 is not less than 0.6; such a setting can improve the rectifying effect of the rectifying plate 40, and reduce the flow resistance of the rectifying plate 40, and facilitate the air outlet 12.

[0046] Specifically, the area A1 of the hollow portion 44 can be understood as the sum of the areas of the multiple hollow portions 44 divided by a number of rectifying strips in the rectifying plate 40, and the area of ​​the hollow portion 44 may account for no less than 0.6 of the area of ​​the rectifying plate 40, so as to increase the rectifying portion of the rectifying plate 40, thereby improving the rectifying effect of the rectifying plate 40 on the airflow, so as to reduce the noise generated by the fan assembly 30; and the flow area of ​​the airflow in the rectifying plate 40 can be increased, thereby reducing the flow resistance of the rectifying plate 40 and facilitating the passage of airflow.

The airflow can flow along the waist of the trapezoid, so that the airflow is discharged in a predetermined direction, thereby improving the straightening effect of the straightening strip to reduce the airflow noise generated by the fan assembly 30.

[0048] Reference Figures 1 to 6 In other embodiments of the present invention, the rectifying strip forms a straight line, a free curve or an arc line in the extension direction to rectify the airflow according to actual conditions, thereby reducing the airflow noise generated by the fan assembly 30.

[0049] The extending direction may be perpendicular to the air flow direction of the air outlet 12 .
