DETAILED DESCRIPTION
[0020] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.
[0021] The air conditioner outdoor unit provided in the embodiment of the present application is as follows Figures 1 to 3 As shown, it includes: a housing 100, wherein the interior of the housing 100 has a heat exchange cavity 110 and an installation cavity 120, wherein the heat exchange cavity 110 is located on one side of the installation cavity 120 in the left-right direction; a heat exchanger 200 and a compressor 300, wherein the heat exchanger 200 is located in the heat exchange cavity 110, and the compressor 300 is located in the installation cavity 120; a fan assembly 400 having a fan blade 410 and a motor 420, wherein the fan assembly 400 is located in the heat exchange cavity 110 and is located on one side of the heat exchanger 200 in the front-to-back direction; and an electric control box 500, wherein the electric control box 500 is located in the heat exchange cavity 110 and is located between the heat exchanger 200 and the fan blade 410 in the front-to-back direction. Among them, the motor 420 is located between the heat exchanger 200 and the fan blade 410 in the front-to-back direction.
[0022] In the outdoor unit of the air conditioner, the motor 420 is located between the heat exchanger 200 and the fan blades 410 in the front-to-back direction, and the electric control box 500 is located in the heat exchange chamber 110 and between the heat exchanger 200 and the fan blades 410 in the front-to-back direction. The electric control box 500 makes full use of the space between the heat exchanger 200 and the fan blades 410, so that the size of the shell 100 in the front-to-back direction is smaller; furthermore, when the fan assembly is running, a first air beam is formed inside the heat exchange chamber 110 to circulate with the outside world. In this way, even if refrigerant leaks in the heat exchange chamber 110, the leaked refrigerant will be blown to the outside world by the first air beam and cannot accumulate to a certain concentration at the electric control box 500 in the heat exchange chamber 110. Therefore, the electric control box 500 will not ignite the refrigerant, so the air conditioner outdoor unit will not have accidents such as fire or explosion, and the use safety is better.
[0023] In some examples, such as Figures 1 to 3 As shown, the electric control box 500 has a first air outlet and a second air outlet, the first air outlet is connected to the area between the heat exchanger 200 and the fan blade 410, and the second air outlet is connected to the outside of the shell 100.
[0024] The fan assembly is located at the front side of the heat exchanger 200. When the fan assembly is running, the heat exchange cavity 110 forms a first air beam that blows from the back to the front. During this process, a negative pressure is formed in the area between the heat exchanger 200 and the fan blade 410. Under the suction effect of the negative pressure, the electric control box 500 forms a second air beam that flows from the outside through the second air outlet, the inside of the electric control box 500 and the first air outlet to the area between the heat exchanger 200 and the fan blade 410. The second air beam will take away the heat inside the electric control box 500, and achieve heat dissipation and cooling of the inside of the electric control box 500. Finally, the second air beam is blown forward to the outside with the first air beam. In this process, even if part of the refrigerant passes through the inside of the electric control box 500 with the second air beam, since the concentration of the refrigerant passing through the inside of the electric control box 500 with the second air beam is particularly low, the area where discharge occurs inside the electric control box 500 will not ignite the refrigerant, and the air conditioner outdoor unit will not have accidents such as fire or explosion.
[0025] In some embodiments, Figures 1 to 3 As shown, the air conditioner outdoor unit further includes: a first air duct, the first air duct is located outside the electric control box 500, and the second air outlet is connected to the outside of the shell 100 through the first air duct.
[0026] When the fan assembly is running, the heat exchange chamber 110 forms a first air beam that blows from the back to the front. During this process, negative pressure is formed in the area between the heat exchanger 200 and the fan blade 410. Under the suction effect of the negative pressure, the electrical control box 500 forms a second air beam that flows from the outside through the first air duct, the second air outlet, the interior of the electrical control box 500 and the first air outlet in sequence to the area between the heat exchanger 200 and the fan blade 410.
[0027] Among them, Figures 1 to 3 As shown, the air conditioner outdoor unit further includes an air duct 600 , the second air outlet is connected to the outside of the housing 100 through the air duct 600 , and the interior of the air duct 600 forms a first air duct.
[0028] In some embodiments, Figure 3 As shown, the bottom wall of the housing 100 is provided with a third air port 111, the first port of the first air duct is connected to the second air port, and the second port of the first air duct is connected to the outside of the housing 100 through the third air port 111. The third air port 111 is provided on the bottom wall of the housing 100, so that water is less likely to enter the interior of the electric control box 500 from the third air port 111 through the first air duct, causing internal short circuit damage to the electric control box 500. Figure 3 As shown, a filter 700 is provided at the third air outlet 111, and the filter 700 prevents dust, insects, mice, etc. from entering the interior of the electric control box 500 from the first air duct, so that the interior of the electric control box 500 is less likely to be dirty or damaged. Among them, the filter 700 is set as a filter net.
[0029] It can be, for example Figures 1 to 3As shown, the third air outlet 111 is located at the bottom wall of the heat exchange chamber 110 (it may be that the third air outlet 111 is located at the front side of the fan blade 410; or it may be that the third air outlet 111 is located at the rear side of the fan blade 410, etc.), and the first air duct is located inside the heat exchange chamber 110; or it may be that the third air outlet 111 is located at the bottom wall of the installation chamber 120, and the first air duct is located inside the installation chamber 120; or it may be that the third air outlet 111 is located at the front side wall of the shell 100; or it may be that the third air outlet 111 is located at the rear side wall of the shell 100; or it may be that the third air outlet 111 is located at the left side wall of the shell 100; or it may be that the third air outlet 111 is located at the right side wall of the shell 100, etc.; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design idea of the present utility model, and will not be repeated here, and all should fall within the protection scope of the present application.
[0030] In some examples, such as Figures 1 to 4 As shown, the air conditioner outdoor unit further includes: a second air duct 820 , and the first air outlet is connected to the area between the heat exchanger 200 and the fan blade 410 through the second air duct 820 .
[0031] When the fan assembly is running, the heat exchange chamber 110 forms a first air beam blowing from the back to the front. During this process, negative pressure is formed in the area between the heat exchanger 200 and the fan blade 410. Under the suction effect of the negative pressure, the electrical control box 500 forms a second air beam from the outside that flows to the area between the heat exchanger 200 and the fan blade 410 through the third air port 111, the first air duct, the second air port, the interior of the electrical control box 500, the first air port, and the second air duct 820 in sequence.
[0032] In some embodiments, Figures 1 to 4 As shown, the second air duct 820 is a curved air duct, the first port of the curved air duct is connected to the first air outlet, and the second port of the curved air duct faces downward, so that the water in the heat exchange chamber 110 is less likely to enter the interior of the electric control box 500 from the second port of the curved air duct through the curved air duct and the first air outlet in sequence, causing an internal short circuit of the electric control box 500. The second air duct 820 is provided with a protective grille 830, which prevents insects, mice, etc. from entering the interior of the electric control box 500 from the second air duct 820, so that the interior of the electric control box 500 is less likely to be damaged.
[0033] Among them, Figures 1 to 4As shown, the air conditioner outdoor unit also includes a protective cover 800, which is located outside the electric control box 500 and is covered on the electric control box 500. Baffles 810 are alternately arranged between the protective cover 800 and the electric control box 500. The baffles 810, the protective cover 800 and the electric control box 500 together form a curved air duct. This solution has a simple structure and is easy to manufacture. Among them, one or more baffles 810 are provided with a protective grille 830, the protective cover 800 is located between the heat exchanger 200 and the fan blade 410, and the first air outlet is located between the heat exchanger 200 and the fan blade 410.
[0034] In some examples, such as Figure 2 and Figure 3 As shown, the electric control box 500 includes: a box body 510, a heat exchange cavity 110 and an installation cavity 120 separated by a partition 130, the box body 510 is located in the heat exchange cavity 110 and is arranged on the side of the partition 130, the side of the box body 510 facing away from the partition 130 and the top of the box body 510 are provided with openings, and the second air outlet is located at the front side plate of the box body 510; and a folded box cover 520, which is covered at the opening of the box body 510, the first air outlet is located at the left side plate of the box cover 520, and the protective cover 800 is covered on the left side plate of the box cover 520.
[0035] like Figures 1 to 3 As shown, this solution only requires removing the top cover 140 of the shell 100 and the box cover 520 of the electric control box 500 to inspect the interior of the box body 510 (ie, the electric control board inside the box body 510), making the inspection process of the electric control box 500 simpler.
[0036] The air conditioner (not shown in the figure) provided in the embodiment of the present application includes the air conditioner outdoor unit described in any of the above embodiments.
[0037] This air conditioner has all the advantages of the air conditioner outdoor unit provided by any of the above embodiments, which will not be described in detail here.
[0038] To summarize, in the air-conditioning outdoor unit provided in the embodiment of the present application, the electronic control box is located in the heat exchange chamber and between the heat exchanger and the fan blades in the front-to-back direction, so that the space between the heat exchanger and the fan blades is fully utilized, so that the size of the shell in the front-to-back direction is smaller; furthermore, when the fan assembly is running, a first wind beam is formed inside the heat exchange chamber to circulate with the outside world. In this way, even if refrigerant leakage occurs in the heat exchange chamber, the leaked refrigerant will be blown to the outside world by the first wind beam and cannot accumulate to a certain concentration at the electronic control box in the heat exchange chamber. Therefore, the electronic control box will not ignite the refrigerant, and thus the air-conditioning outdoor unit will not have accidents such as fire or explosion, and is safer to use.
