[0039] Figure 1 Schematic diagram of the structure of an air conditioner according to an embodiment of the present invention. Figure 1As shown, and reference Figures 2 to 6 An embodiment of the present invention provides an air conditioner, which includes a housing 100 , a heat exchanger 200 and an electric control box 300 .

[0040] An air inlet 110 is formed on the front side wall of the shell 100, and the heat exchanger 200 is arranged in the shell 100; the electrical control box 300 extends along the length direction of the shell 100, and the distance between at least part of the front side wall of the electrical control box 300 and the air inlet 110 gradually increases from top to bottom, and the lower side wall of the electrical control box 300 is spaced apart from the heat exchanger 200.

[0041] Specifically, the heat exchanger 200 extends along the length of the housing 100. The air inlet 110 is provided on the front side wall of the housing 100, which can increase the application scenarios of the air conditioner and facilitate the installation of the air conditioner in the cabinet. The function of the heat exchanger 200 is to transfer heat through the process of condensation or evaporation to regulate the indoor temperature, humidity and air quality. Specifically, heat is exchanged between the air and the refrigerant in the heat exchanger 200. In summer, the indoor temperature is lowered; in winter, the indoor temperature is raised.

[0042] In this embodiment, the electrical control box 300 extends along the length of the housing 100, giving it an elongated shape. This accommodates the required components and reduces its thickness. Because the lower sidewall of the electrical control box 300 is spaced apart from the heat exchanger 200, the electrical control box 300 does not cover or obstruct the heat exchanger 200. Compared to the prior art, this increases the effective heat exchange area of ​​the heat exchanger 200, improving heat exchange efficiency and thus enabling the air conditioner to achieve better heat exchange performance.

[0043] On the other hand, the distance between at least part of the front side wall of the electrical control box 300 and the air inlet 110 gradually increases from top to bottom, which is beneficial for guiding part of the airflow flowing into the air inlet 110 backward and downward to the gap between the lower side wall of the electrical control box 300 and the heat exchanger 200, increasing the backward flow distance of the airflow, which is beneficial for improving the heat exchange efficiency of the rear part of the heat exchanger 200.

[0044] like Figures 1 to 3 As shown, in some optional embodiments of the present invention, the upper edge of the air inlet 110 extends to the top of the housing 100 .

[0045] like Figure 2 As shown, in some optional embodiments of the present invention, at least part of the front side wall of the electric control box 300 is an arc-shaped structure. In other words, at least part of the front side wall of the electric control box is an arc surface, which can reduce the noise during the flow of air.

[0046] Furthermore, if Figure 2As shown, the distance between the entire front side wall of the electric control box 300 and the air inlet 110 gradually increases from top to bottom. The entire front side wall of the electric control box 300 is an arc-shaped structure, which is beneficial to further improve the wind guiding effect and is more conducive to the airflow flowing backward and downward.

[0047] like Figure 1 、 Figures 3 to 5 As shown, in some optional embodiments of the present invention, at least part of the front side wall of the electric control box 300 is tilted toward the rear and downward. In other words, at least part of the front side wall of the electric control box is a slope, which is easy to process and manufacture.

[0048] Furthermore, if Figure 1 、 Figures 3 to 5 As shown, the distance between the entire front side wall of the electric control box 300 and the air inlet 110 gradually increases from top to bottom, and the entire front side wall of the electric control box 300 is tilted toward the rear and lower part, which is beneficial to further improve the wind guiding effect and is more conducive to the airflow flowing toward the rear and lower part.

[0049] like Figure 4 and Figure 6 As shown, in some optional embodiments of the present invention, a groove 130 is formed on the upper side wall of the housing 100, with the opening of the groove 130 facing upward. The electric control box 300 is installed in the groove 130. The shape of the groove 130 is adapted to the outer shape of the electric control box 300, so that the electric control box 300 can be installed outside the housing 100. In this embodiment, the electric control box 300 is arranged outside the housing 100 to prevent condensation from forming on the surface of the electric control box 300.

[0050] like Figures 4 to 6 As shown, in some optional embodiments of the present invention, the front side wall of the groove 130 is formed with a first installation opening 131, the front side wall of the electric control box 300 is formed with a second installation opening 330, and the first installation opening 131 is provided with a first installation cover ( Figures 4 to 6 (The first mounting cover is not shown in the figure). In this embodiment, by providing the first mounting opening 131, the second mounting opening 330, and the first mounting cover, when it is necessary to repair components in the electric control box 300, only the first mounting cover needs to be opened to achieve communication between the interior of the electric control box 300 and the interior of the housing 100, thereby improving repair efficiency.

[0051] In some optional embodiments of the present invention, an electrical control box 300 is disposed within the housing 100. An air inlet passage is formed between the lower sidewall of the electrical control box 300 and the heat exchanger 200. The distance between at least a portion of the front sidewall of the electrical control box 300 and the air inlet 110 gradually increases from top to bottom, thereby forming an air guide structure on the front sidewall of the electrical control box 300. The air guide structure is used to direct airflow rearward and downward into the air inlet passage.

[0052] In some optional embodiments of the present invention, the electrical control box 300 is disposed inside the housing 100. A third mounting opening is formed on the front sidewall of the electrical control box 300, and a second mounting cover is provided over the third mounting opening. When the electrical control box 300 is installed within the housing 100, the second mounting cover can be opened to expose the third mounting opening, allowing access to components within the electrical control box 300.

[0053] like Figure 5 As shown, in some optional embodiments of the present invention, the electrical control box 300 includes a first portion 310 and a second portion 320 along its length. The height of the first portion 310 is greater than the height of the second portion 320, and the length of the first portion 310 is less than the length of the second portion 320. The first portion 310 is used to accommodate capacitors and transformers. In other words, a first accommodating area is formed within the first portion 310, which is used to install capacitors and transformers, etc., and a second accommodating area is formed within the second portion 320, which includes a functional structural area and a docking area. Through the above arrangement, the electrical control box not only meets the requirements of accommodating components, but also minimizes its vertical dimensions, thereby increasing the distance between the lower side wall of the electrical control box 300 and the housing 100, thereby more conducive to airflow to the rear of the heat exchanger 200 and further improving the heat exchange efficiency at the rear of the heat exchanger 200.

[0054] In some optional embodiments of the present invention, the distance between the front side wall of the first portion 310 and the air inlet 110 gradually increases from top to bottom.

[0055] In some optional embodiments of the present invention, the distance between the front side wall of the second portion 320 and the air inlet 110 gradually increases from top to bottom.

[0056] like Figure 5 As shown, in some optional embodiments of the present invention, the distance between the front side wall of the first portion 310 and the air inlet 110 gradually increases from top to bottom, and the distance between the front side wall of the second portion 320 and the air inlet 110 gradually increases from top to bottom, thereby gradually increasing the distance between the entire front side wall of the electrical control box 300 and the air inlet 110 from top to bottom. Compared with the above two embodiments, this embodiment can further improve the air guiding effect, thereby making the heat exchange effect of the heat exchanger 200 more uniform.

[0057] like Figures 1 to 3 As shown, in some optional embodiments of the present invention, the upper edge of the front side wall of the electric control box 300 is spaced apart from the air inlet 110. In other words, the front side wall of the electric control box 300 is spaced apart from the air inlet 110, and does not completely block the air inlet 110, which is more conducive to air intake.

[0058] In some optional embodiments of the present invention, the planes on which the left and right walls of the control box 300 are located are inclined planes, the left wall of the control box 300 is inclined from top to bottom to the right, and the right wall of the control box 300 is inclined from top to bottom to the left.

[0059] like Figures 1 to 3 As shown, in some optional embodiments of the present invention, the heat exchanger 200 includes a first heat exchange section 210 and a second heat exchange section 220. The first heat exchange section 210 and the second heat exchange section 220 are arranged at an angle. The first heat exchange section 210 is located in front of the second heat exchange section 220. The front edge of the lower sidewall of the electrical control box 300 is located above the first heat exchange section 210, and the rear edge of the lower sidewall of the electrical control box 300 is located above the second heat exchange section 220. In some alternative embodiments, the heat exchanger 200 can also have other shapes, such as an arc or a straight line. In this embodiment, the first heat exchange section 210 and the second heat exchange section 220 are arranged at an angle, which increases the heat exchange area of ​​the heat exchanger 200. In addition, the lower sidewall of the electrical control box 300 extends from above the first heat exchange section 210 to above the second heat exchange section 220, which increases the rearward air supply distance, thereby improving the heat exchange efficiency of the second heat exchange section 220.

[0060] In some optional embodiments of the present invention, the indoor heat exchanger 200 further includes a third heat exchange section 230. The third heat exchange section 230 is disposed below the first heat exchange section 210. The first heat exchange section 210 and the third heat exchange section 230 are disposed corresponding to the air inlet 110. In this embodiment, the provision of the third heat exchange section 230 can further increase the heat exchange area of ​​the heat exchanger 200, thereby further improving the heat exchange effect of the heat exchanger 200.

[0061] In some optional embodiments of the present invention, an air outlet 120 is further formed on the front side wall of the housing 100 , and the air inlet 110 is located above the air outlet 120 .

[0062] In this embodiment, the air outlet 120 and the air inlet 110 are both arranged on the front side of the shell 100 and are not restricted by the cabinet, which is conducive to the air conditioner meeting the requirements of horizontal embedded installation.

[0063] Furthermore, the air outlet 120 extends along the length direction of the housing 100. Specifically, the housing 100 extends in the left-right direction, and the air outlet 120 extends in the left-right direction, so that the air outlet 120 is an elongated structure, thereby enabling the air outlet 120 to have a larger air outlet area.

[0064] In some optional embodiments of the present invention, the area of ​​the air inlet 110 is larger than the area of ​​the air outlet 120 .

[0065] The area of ​​the air conditioner's air inlet 110 is larger than that of the air outlet 120, which can improve the efficiency of the fan 400. Specifically, by increasing the area of ​​the air inlet 110, the air flow rate can be effectively increased, making the indoor air circulation smoother, helping to improve the cooling or heating efficiency of the air conditioner, ensuring that the indoor temperature reaches the set value more quickly, thereby providing a more comfortable and efficient indoor environment. In addition, this design can effectively avoid the problem of reduced airflow velocity caused by an oversized air outlet 120, maintaining the airflow velocity within a suitable range, thereby improving the user experience and comfort.

[0066] In some embodiments of the present invention, a fan 400 is further provided in the housing 100 . The fan 400 extends along the length of the housing 100 and is used to promote the formation of an air flow that enters the housing from the air inlet 110 and is blown out from the air outlet 120 .

[0067] In some embodiments of the present invention, the air conditioner is a wall-mounted air conditioner, which has the advantages of being easy to install and move.

[0068] In some embodiments of the present invention, the air conditioner is a cabinet-embedded air conditioner. In this embodiment, the cabinet-embedded air conditioner is usually installed inside a cabinet, so that the air conditioner and the furniture are integrated, making the room more beautiful and neat, and reducing the noise during operation of the air conditioner, thereby improving the user experience.
