DETAILED DESCRIPTION

[0025] In order to make the above objectives, features and advantages of the present application more apparent and comprehensible, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 , an air conditioner 100 is provided according to an embodiment of the present application, which is used to regulate indoor air temperature. The air conditioner 100 can reasonably arrange the positions of an evaporator 120 and a cross flow fan 130, improve air outlet volume, improve utilization rate of the evaporator 120, improve heat exchange efficiency, and improve user experience.

[0027] It should be noted that the air conditioner 100 is an air conditioner cabinet, which is placed on the ground along the vertical direction and can blow hot air or cold air into the room to realize the functions of heating or cooling of the air conditioner 100.

[0028] The air conditioner 100 includes a housing 110, an evaporator 120, a cross-flow fan 130, a first reinforcing strip 140, a second reinforcing strip 150, and an evaporator bracket 160. The evaporator 120, cross-flow fan 130, first reinforcing strip 140, second reinforcing strip 150, and evaporator bracket 160 are all installed inside the housing 110, which serves to shield and protect the evaporator 120, cross-flow fan 130, first reinforcing strip 140, second reinforcing strip 150, and evaporator bracket 160.

[0029] Furthermore, a cross-flow fan 130 is disposed inside the evaporator 120. The cross-flow fan 130 generates negative pressure to drive airflow and form an outlet airflow. The evaporator 120 exchanges heat with the outlet airflow to enable it to perform heating or cooling functions. A first reinforcing strip 140 and a second reinforcing strip 150 are disposed opposite each other on the inner sides of the outer casing 110 and are both fixedly connected to the outer casing 110. The evaporator 120 and the cross-flow fan 130 are both disposed between the first reinforcing strip 140 and the second reinforcing strip 150. The first reinforcing strip 140 and the second reinforcing strip 150 work together to improve the strength of the outer casing 110 and prevent deformation or bending. The evaporator 120 is mounted on an evaporator bracket 160, which supports and fixes the evaporator 120. The evaporator bracket 160 abuts against the first reinforcing strip 140 to prevent air leakage.

[0030] In this embodiment, both the first reinforcing strip 140 and the second reinforcing strip 150 extend vertically to reinforce the outer casing 110 in the vertical direction, share the weight of the outer casing 110 in the vertical direction, prevent the outer casing 110 from deforming after the air conditioner 100 has been used for a long time, and extend the service life of the air conditioner 100.

[0031] It is worth noting that the cross-flow fan 130 is located in the middle of the outer casing 110, and the evaporator 120 is located between the first reinforcing strip 140 and the cross-flow fan 130. The ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the cross-flow fan 130 ranges from 0.8 to 1.5. A reasonable ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the cross-flow fan 130 can control the distance between the evaporator 120 and the cross-flow fan 130, thereby increasing the airflow of the air conditioner 100. For ease of understanding, the distance between the first reinforcing strip 140 and the evaporator 120 is denoted as the first distance A, and the distance between the evaporator 120 and the cross-flow fan 130 is denoted as the second distance B. The ratio of the first distance A to the second distance B ranges from 0.8 to 1.5.

[0032] In this embodiment, the ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the cross-flow fan 130 is 1, that is, the distance between the first reinforcing strip 140 and the evaporator 120 is equal to the distance between the evaporator 120 and the cross-flow fan 130, so as to further improve the air volume of the air conditioner 100. However, it is not limited to this. In other embodiments, the ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the cross-flow fan 130 can be 0.8 or 1.5. There is no specific limitation on the ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the cross-flow fan 130.

[0033] Furthermore, the ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the second reinforcing strip 150 ranges from 0.45 to 1. A reasonable ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the second reinforcing strip 150 can control the size of the gap on both sides of the evaporator 120, thereby improving the utilization rate of the evaporator 120 and thus increasing its heat exchange efficiency. For ease of understanding, the distance between the evaporator 120 and the second reinforcing strip 150 is represented as the third distance C, and the ratio of the first distance A to the third distance C ranges from 0.45 to 1.

[0034] In this embodiment, the ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the second reinforcing strip 150 is 0.7, but it is not limited to this. In other embodiments, the ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the second reinforcing strip 150 can be 0.45 or 1. The ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the second reinforcing strip 150 is not specifically limited.

[0035] Specifically, the first reinforcing strip 140 and the second reinforcing strip 150 are arranged opposite each other along a preset direction. The distance between the first reinforcing strip 140 and the evaporator 120 is the minimum distance between the first reinforcing strip 140 and the evaporator 120 in the preset direction. The distance between the evaporator 120 and the second reinforcing strip 150 is the minimum distance between the second reinforcing strip 150 and the evaporator 120 in the preset direction. The distance between the evaporator 120 and the cross-flow fan 130 is the minimum distance between the evaporator 120 and the cross-flow fan 130.

[0036] The evaporator 120 includes a first straight section 121, a bent section 122, and a second straight section 123 connected in sequence. In this embodiment, the first straight section 121, the bent section 122, and the second straight section 123 are integrally formed to improve the connection strength. A cross-flow fan 130 is disposed on the concave side of the bent section 122. Under the negative pressure generated by the cross-flow fan 130, outside air passes through the evaporator 120 and converges to form an exhaust airflow, which is then blown into the room to regulate the indoor temperature. Specifically, the first straight section 121 is arranged perpendicular to a preset direction to increase the airflow area and improve the heat exchange efficiency.

[0037] Furthermore, the angle formed by the extension of the first straight section 121 and the extension of the second straight section 122 ranges from 45 degrees to 65 degrees, meaning the bending angle of the bending section 122 ranges from 45 degrees to 65 degrees. A reasonable bending angle for the bending section 122 can improve the heat exchange efficiency of the evaporator 120, enhance its heat exchange effect, and ensure effective heat exchange of the outlet airflow. For ease of understanding, the bending angle of the bending section 122 is denoted as angle α, which ranges from 45 degrees to 65 degrees.

[0038] In this embodiment, the bending angle of the bending segment 122 is 55 degrees, but it is not limited to this. In other embodiments, the bending angle of the bending segment 122 can be 45 degrees or 65 degrees. There is no specific limitation on the bending angle of the bending segment 122.

[0039] Furthermore, the ratio of the distance between the first straight section 121 and the cross-flow fan 130 and the distance between the second straight section 123 and the cross-flow fan 130 ranges from 0.5 to 1. A reasonable ratio of the distance between the first straight section 121 and the cross-flow fan 130 and the distance between the second straight section 123 and the cross-flow fan 130 can control the size of the gap on both sides of the cross-flow fan 130, improve air outlet efficiency, and increase air volume. Specifically, since the distance between the first straight section 121 and the cross-flow fan 130 is less than or equal to the distance between the second straight section 123 and the cross-flow fan 130, the distance between the first straight section 121 and the cross-flow fan 130 is the minimum distance between the evaporator 120 and the cross-flow fan 130. That is, the distance between the first straight section 121 and the cross-flow fan 130 is the distance between the evaporator 120 and the cross-flow fan 130. In other words, the distance between the first straight section 121 and the cross-flow fan 130 is the second distance B. For ease of understanding, the distance between the second straight section 123 and the cross-flow fan 130 is represented as the fourth distance D. The ratio of the second distance B to the fourth distance D ranges from 0.5 to 1.

[0040] In this embodiment, the ratio of the distance between the first straight section 121 and the cross-flow fan 130 and the distance between the second straight section 123 and the cross-flow fan 130 is 0.8, but it is not limited to this. In other embodiments, the ratio of the distance between the first straight section 121 and the cross-flow fan 130 and the distance between the second straight section 123 and the cross-flow fan 130 can be 0.5 or 1. The ratio of the distance between the first straight section 121 and the cross-flow fan 130 and the distance between the second straight section 123 and the cross-flow fan 130 is not specifically limited.

[0041] The outer casing 110 includes a rear panel 111 and a front panel 112. The rear panel 111 is connected to the front panel 112 and together they form an internal cavity 113. The evaporator 120, the cross-flow fan 130, the first reinforcing strip 140, the second reinforcing strip 150, and the evaporator bracket 160 are all disposed within the internal cavity 113. The first reinforcing strip 140 and the second reinforcing strip 150 are both fixedly connected to the rear panel 111 to improve the strength of the rear panel 111 and prevent the rear panel 111 from deforming or bending.

[0042] Please refer to the reference. Figure 4 and Figure 5 It should be noted that the rear panel 111 is arc-shaped and has an air inlet area 114 with an air inlet (not shown). The evaporator 120 has an air inlet side 124. The position of the air inlet area 114 corresponds to the position of the air inlet side 124. Under the negative pressure generated by the cross-flow fan 130, outside air enters the internal cavity 113 through the air inlet area 114 of the rear panel 111 and passes through the air inlet side 124 of the evaporator 120 to form an outlet airflow. Specifically, the ratio of the arc length of the air inlet area 114 to the cross-sectional length of the air inlet side 124 ranges from 0.8 to 1.2. A reasonable ratio of the arc length of the air inlet area 114 to the cross-sectional length of the air inlet side 124 enables the evaporator 120 to efficiently exchange heat with the outside air entering the internal cavity 113, improving reliability. For ease of understanding, the arc length of the air intake area 114 is represented as the first length E, and the cross-sectional length of the air intake side 124 is represented as the second length F. The ratio of the first length E to the second length F ranges from 0.8 to 1.2.

[0043] In this embodiment, the ratio of the arc length of the air intake region 114 to the cross-sectional length of the air intake side 124 is 1, that is, the arc length of the air intake region 114 and the cross-sectional length of the air intake side 124 are equal. However, it is not limited to this. In other embodiments, the ratio of the arc length of the air intake region 114 to the cross-sectional length of the air intake side 124 can be 0.8 or 1.2. There is no specific limitation on the ratio of the arc length of the air intake region 114 to the cross-sectional length of the air intake side 124.

[0044] Please continue to refer to Figure 2In this embodiment, the evaporator support 160 is provided with an air guide slope 161. The air guide slope 161 is gradually positioned closer to the evaporator 120 along the direction from the first reinforcing strip 140 to the evaporator 120, so as to guide the outside air entering the internal cavity 113, accelerate the speed at which the outside air flows into the evaporator 120, improve the heat exchange efficiency of the evaporator 120, and prevent the outside air from generating eddies between the evaporator support 160 and the evaporator 120.

[0045] Please refer to the reference. Figure 6 , Figure 7 and Figure 8 It should be noted that in existing cabinet air conditioners, the ratio of the first spacing A to the second spacing B is 0.7, the ratio of the first spacing A to the third spacing C is 0.26, the included angle α is 30 degrees, the ratio of the second spacing B to the fourth spacing D is 0.45, and the ratio of the first length E to the second length F is 0.76. In this embodiment of the invention, the air conditioner 100 adjusts these five parameters—the ratio of the first spacing A to the second spacing B, the ratio of the first spacing A to the third spacing C, the included angle α, the ratio of the second spacing B to the fourth spacing D, and the ratio of the first length E to the second length F—to increase the airflow, improve the utilization rate of the evaporator 120, and enhance the heat exchange efficiency.

[0046] Specifically, the air output volume of the cabinet-type air conditioner in the prior art is compared with that of the air conditioner 100 in the embodiment of the present invention, and the results are shown in the table below.

[0047]

[0048] As can be seen from the table, at the same rotational speed, the air volume of a conventional cabinet air conditioner is significantly less than that of the air conditioner 100 in this embodiment of the invention; and the difference between the air volume of the air conditioner 100 and the air volume of the cabinet air conditioner gradually increases as the rotational speed increases. Therefore, the air conditioner 100 in this embodiment of the invention can effectively improve the air volume by reasonably adjusting the arrangement of the evaporator 120 and the cross-flow fan 130.

[0049] In the air conditioner 100 described in this embodiment of the invention, a first reinforcing strip 140 is fixedly connected to the inner side of the outer casing 110, a cross-flow fan 130 is disposed in the middle of the outer casing 110, and an evaporator 120 is disposed between the first reinforcing strip 140 and the cross-flow fan 130. The ratio of the distance between the first reinforcing strip 140 and the evaporator 120 to the distance between the evaporator 120 and the cross-flow fan 130 ranges from 0.8 to 1.5. Compared with the prior art, the air conditioner 100 provided by the present invention, by adopting a certain ratio range for the distance between the first reinforcing strip 140 and the evaporator 120 and the distance between the evaporator 120 and the cross-flow fan 130, can reasonably arrange the positions of the evaporator 120 and the cross-flow fan 130, thereby increasing the air volume, improving the utilization rate of the evaporator 120, improving the heat exchange efficiency, and enhancing the user experience.

[0050] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
