[0050] CombineFigures 1 to 3 As shown in the drawings, the present embodiment provides an external air conditioner, which comprises an outdoor machine box 10, a first heat exchange assembly 20, a first fan assembly 30, a second heat exchange assembly 40, a compressor assembly 50, a second fan assembly 60, a first air duct assembly 70 and a second air duct assembly 80. The cooperation relationship and specific structure of each assembly are described below.

[0051] The outdoor machine box 10 has a first machine compartment 11 and a second machine compartment 12, which is arranged adjacent to the first machine compartment 11. As a specific distribution manner, the second machine compartment 12 is located above the first machine compartment 11. As a specific arrangement manner, the outdoor machine box 10 is an integrated machine box, and a first partition plate 13 is arranged transversely in the outdoor machine box 10, which divides the outdoor machine box 10 into the first machine compartment 11 at the lower side and the second machine compartment 12 at the upper side.

[0052] The first heat exchange assembly 20 and the compressor assembly 50 are arranged in the first machine compartment 11; and the first fan assembly 30 is arranged at the heat exchange opening of the front panel of the first machine compartment.

[0053] The second heat exchange assembly 40 and the second fan assembly 60 are arranged in the second machine compartment 12, and the heat exchange manner of the second heat exchange assembly 40 is opposite to that of the first heat exchange assembly 20; and the compressor assembly 50 is connected in series with the first heat exchange assembly 20 and the second heat exchange assembly 40 in the form of refrigerant transmission. The opposite heat exchange manner herein refers to that the second heat exchange assembly 40 is used as a condensing assembly while the first heat exchange assembly 20 is used as an evaporating assembly, or the second heat exchange assembly 40 is used as an evaporating assembly while the first heat exchange assembly 20 is used as a condensing assembly; that is, the refrigerant system composed of the compressor assembly 50, the first heat exchange assembly 20 and the second heat exchange assembly 40 can perform a forward refrigeration cycle and a reverse heating cycle.

[0054] In combination with Figure 4 As shown in the drawings, one end of the first air duct assembly 70 is connected to the first air opening 121 arranged on the second machine compartment 12, and the other end is used for connecting to an indoor high-position air opening; one end of the second air duct assembly 80 is connected to the second air opening 122 arranged on the second machine compartment 12, and the other end is used for connecting to an indoor low-position air opening. The communication flow path of the first air opening 121 and the second air opening 122 in the second machine compartment 12 passes through the second fan assembly 60 and the second heat exchange assembly 40. The indoor high-position air opening described above refers to an air opening arranged on a higher position (for example, on the wall close to the ceiling) of a room wall 210, and the indoor low-position air opening refers to an air opening arranged on a higher position (for example, on the wall close to the ground) of a room wall 210. In addition, the indoor high-position air opening and the indoor low-position air opening are preferably arranged on different walls.

[0055] The above-mentioned external air conditioner divides the outdoor machine box 10 into a first machine compartment 11 and a second machine compartment 12, and sets all the components of the outdoor machine in the prior art in the first machine compartment 11, and sets all the components of the indoor machine in the prior art in the second machine compartment 12; thus, the components of the air conditioner all work outdoors, greatly reducing noise pollution; meanwhile, the first air pipe assembly 70 is connected to the indoor high-position air outlet, the second air pipe assembly 80 is connected to the indoor low-position air outlet, and the indoor high-position air outlet and the indoor low-position air outlet can form a significant drop and a larger spacing, and the air volume circulation is better.

[0056] As shown in Figures 1 to 5 , the other end of the first air pipe assembly 70 is provided with a first sealing butt joint seat 71, and the first sealing butt joint seat 71 is in communication and sealing butt joint with the corresponding opening of the indoor high-position air outlet on the building body (wall body); the other end of the second air pipe assembly 80 is provided with a second sealing butt joint seat 81, and the second sealing butt joint seat 81 is in communication and sealing butt joint with the corresponding opening of the indoor low-position air outlet on the building body (wall body).

[0057] Continuing to refer to Figure 5 , as a preferred embodiment, the first sealing butt joint seat 71 is provided with a first ducted fan 72; the second sealing butt joint seat 81 is provided with a second ducted fan 82.

[0058] As shown in Figure 3 and Figure 6 , a second partition plate 14 is longitudinally arranged in the second machine compartment 12, and the second partition plate 14 divides the second machine compartment 12 into a left side chamber 13 and a right side chamber 14; a first air outlet 121 is formed in the rear part of the left side wall of the left side chamber 123, and a second air outlet 122 is formed in the rear part of the right side wall of the right side chamber 124, and a filter screen is arranged on each of the first air outlet 121 and the second air outlet 122; a communication opening 141 is formed in the front part of the second partition plate 14, and the communication opening 141 is in communication with the left side chamber 123 and the right side chamber 124. In this way, the arrangement of the second partition plate 14 for dividing the second machine compartment forms a U-shaped air path 109, and the U-shaped air path 109 has a longer heat exchange distance than an ordinary straight air duct, and is more conducive to improving the heat exchange effect.

[0059] As shown in Figure 3 , Figure 6 and Figure 7 , the second fan assembly 60 and the second heat exchange assembly 40 are both two groups, and one group of the second fan assembly 60 and the second heat exchange assembly 40 is arranged in the left side chamber 123 and the right side chamber 124, respectively. In this way, in cooperation with the U-shaped air path 109 described above, the air flow rate can be improved, and thus the heat exchange efficiency can be improved.

[0060] As shown in Figure 6 and Figure 7As shown, more specifically, a second fan assembly 60 is installed at the rear of the left chamber 123, and a second heat exchange assembly 40 is installed at the front (in conjunction with...). Figure 3 , Figure 7 (Not shown in the image); A second heat exchange assembly 40 is installed at the rear of the right-side chamber 124 (in conjunction with...) Figure 3 , Figure 7 (Not shown in the middle) A set of second fan components 60 is arranged at the front. This staggered arrangement can avoid the resonance of the two sets of second fan components 60 and generate large noise, while also facilitating the airflow in the U-shaped air passage 109 to fully exchange heat with the two sets of second heat exchange components 40.

[0061] Combination Figure 8 and Figure 9 As shown, the first partition 13 has an upward-curving edge with a slot 131. The inner wall of the outdoor unit housing 10 has a (not shown) locking block that engages with the slot 131 to restrict the first partition 13 from sliding down, allowing it to be positioned approximately in the middle of the outdoor unit housing 10. This structure facilitates assembly, and the first partition 13 with its upward-curving edge can act as a drip tray, preventing condensate from the second heat exchange component 40 in the second housing 12 from flowing irregularly downwards from the periphery.

[0062] As a further implementation method, combined with Figure 8 , Figure 9 and Figure 10 As shown, a drain hole (not shown) is provided on the first partition 13. A drain pipe 90 connected to the drain hole is arranged below the first partition 13. The drain pipe 90 is located above the first heat exchange component 20 and is provided with multiple drain nozzles 91. In this embodiment, by providing a drain mechanism on the first partition 13, the condensate generated by the second compartment 12 can be used to exchange heat with the first heat exchange component 20 in the first compartment 11, thereby improving the heat exchange efficiency.

[0063] The control method for the aforementioned external air conditioner includes:

[0064] When the compressor assembly 50, the first heat exchange assembly 20 and the second heat exchange assembly 40 are operating in cooling mode, the air supply direction of the second fan assembly 60 is controlled so that the first duct assembly 70 performs air supply operation and the second duct assembly 80 performs air return operation.

[0065] When the compressor assembly 50, the first heat exchange assembly 20 and the second heat exchange assembly 40 are operating in heating mode, the air supply direction of the second fan assembly is controlled so that the first duct assembly 70 performs air supply operation and the second duct assembly 80 performs air return operation.

[0066] In this way, indoor refrigeration and heating two-way circulation heat exchange can be performed, and the effect of "cold air from top to bottom, hot air from bottom to top" can be achieved.

[0067] The above disclosure is only the preferred embodiment of the application, and of course cannot limit the scope of the application. Therefore, equivalent changes made according to the claims of the application are still within the scope of the application.
