This places high demands on installation and is prone to refrigerant leaks due to installation problems. Furthermore, the exposed connecting pipes are unsightly. Additionally, when the air conditioner is in cooling mode, moisture in the warm indoor air condenses on the surface of the indoor heat exchanger after heat exchange, easily causing dripping. Some existing solutions typically drain the condensate directly outdoors; however, this wastes energy, resulting in low heat exchange efficiency and high power consumption. Utility Model Content

[0024] This utility model provides the following technical solution:

[0025] An air conditioner, including the aforementioned outdoor unit.

[0026] The embodiments of this utility model have the following beneficial effects:

[0027] This invention integrates the indoor and outdoor heat exchangers into the outdoor unit, resulting in a more compact structure.

[0046] Example

[0047] Please refer to the following: Figure 1 and Figure 2 This embodiment provides an outdoor unit 10 for use in an air conditioner. The outdoor unit 10 includes a housing 100, an indoor heat exchanger 200, an outdoor heat exchanger 300, and a condensate recovery device 400.

[0048] The outer casing 100 has a first chamber 110 and a second chamber 120, with the first chamber 110 located above the second chamber 120. The indoor heat exchanger 200 is disposed in the first chamber 110, and the outdoor heat exchanger 300 is disposed in the second chamber 120.

[0049] Please combine Figure 3 In addition, the condensate recovery device 400 is located below the indoor heat exchanger 200. The condensate recovery device 400 is provided with a drain hole 422, which communicates with the second chamber 120 and is located above the outdoor heat exchanger 300.

[0050] In this embodiment, the indoor heat exchanger 200 and the outdoor heat exchanger 300 are integrated into the outdoor unit 10, resulting in a more compact structure. This facilitates the connection and installation between the two heat exchangers and prevents refrigerant leakage. Furthermore, installing the indoor heat exchanger 200 inside the outdoor unit 10 avoids indoor water dripping and also facilitates condensate energy recovery.

[0051] When the outdoor unit 10 is running, indoor air enters the first chamber 110 and exchanges heat with the indoor heat exchanger 200. Water vapor in the indoor air condenses on the surface of the indoor heat exchanger 200. The condensate falls into the condensate recovery device 400 under its own gravity and is then discharged into the second chamber 120 through the drain hole 422 on the condensate recovery device 400. Since the drain hole 422 is located above the outdoor heat exchanger 300, the condensate flows to the surface of the outdoor heat exchanger 300, cooling it down and thus improving the heat exchange efficiency of the outdoor heat exchanger 300, reducing the compressor's workload, improving overall energy efficiency, and saving energy.

[0052] It should be noted that the operating conditions of the outdoor unit 10 in this embodiment all correspond to the cooling mode of the air conditioner.

[0053] In some embodiments, the outdoor unit 10 further includes a circulating fan 500, an outdoor fan 600, and a compressor 700.

[0054] The circulating fan 500 is located in the first chamber 110, and the outdoor fan 600 and compressor 700 are located in the second chamber 120.

[0055] In operation, the circulating fan 500 draws indoor return air and / or fresh air into the first chamber 110, allowing the indoor return air and / or fresh air to exchange heat with the indoor heat exchanger 200. The cooled air is then returned to the room by the circulating fan 500. During this process, the refrigerant in the indoor heat exchanger 200 absorbs heat from the air and its temperature rises. It then flows into the outdoor heat exchanger 300, where it exchanges heat with the refrigerant and its temperature drops. Finally, it flows back to the indoor heat exchanger 200 to cool the air.

[0056] Meanwhile, the refrigerant in the outdoor heat exchanger 300 absorbs heat from the refrigerant in the indoor heat exchanger 200, causing its temperature to rise, and then dissipates the heat to the surroundings. Correspondingly, the outdoor fan 600 continuously draws air from the outside environment through the second chamber 120, accelerating the heat dissipation of the outdoor heat exchanger 300.

[0057] It should be noted that the diameter of the drain hole 422 must be large enough to ensure that the gravity of the condensate can overcome the negative pressure suction of the circulating fan 500 and the surface tension of the water film. For example, the diameter of the drain hole 422 is greater than 5 mm.

[0058] Please refer to the following: Figure 2 , Figure 3 and Figure 4 In some embodiments, a heat exchange chamber 131 is formed by tightly attaching a layer of heat insulation material to the inner wall of the first chamber 110. A first water collection tank 132 is provided on the bottom surface of the inner wall of the heat exchange chamber 131. A first drain hole 133 is provided at the bottom of the first water collection tank 132, and the first drain hole 133 is located above the condensate recovery device 400.

[0059] Accordingly, the indoor heat exchanger 200 is disposed in the heat exchange chamber 131.

[0060] When the outdoor unit 10 is running, the condensate on the surface of the indoor heat exchanger 200 falls into the bottom of the heat exchange chamber 131 under its own gravity, and gathers in the first water collection tank 132 on the bottom surface of the inner wall of the heat exchange chamber 131. Then, it continues to be discharged downward to the condensate recovery device 400 from the first drain hole 133 at the bottom of the first water collection tank 132.

[0061] For example, the inner wall of the first chamber 110 is tightly attached with a layer of expanded polypropylene (EPP) plastic foam to form a heat insulation material layer 130. The heat insulation material layer 130 is adapted to the shape of the first chamber 110, and the inner periphery of the heat insulation material layer 130 forms a heat exchange cavity 131.

[0062] In addition, the circulating fan 500 is also installed in the heat exchange chamber 131.

[0063] In use, the circulating fan 500 draws indoor return air and / or fresh air into the first chamber 110, specifically into the heat exchange chamber 131, where the indoor return air and / or fresh air exchange heat with the indoor heat exchanger 200. During this process, the thermal insulation material layer 130 prevents heat exchange between the heat exchange chamber 131 and the external environment of the outer shell 100, ensuring the cooling effect of the indoor heat exchanger 200 on the indoor return air and / or fresh air.

[0064] Please see Figure 2 In this embodiment, the top of the thermal insulation material layer 130 is open, and the indoor heat exchanger 200 and the circulating fan 500 are installed into the heat exchange chamber 131 from the open end of the thermal insulation material layer 130. Correspondingly, a thermal insulation layer 140 is also provided in the first chamber 110, and the thermal insulation layer 140 covers the top of the thermal insulation material layer 130. In addition, the thermal insulation layer 140 has a gas inlet 141 and a gas outlet 142. The circulating fan 500 draws indoor return air and / or fresh air into the heat exchange chamber 131 through the gas inlet 141, and sends the cooled air back into the room through the gas outlet 142.

[0065] Please refer to the following: Figure 4 and Figure 5In some embodiments, the bottom surface of the inner wall of the heat exchange cavity 131 is also provided with a plurality of protrusions 134 at intervals.

[0066] Accordingly, the indoor heat exchanger 200 is placed on the boss 134.

[0067] Since the indoor heat exchanger 200 is placed on the boss 134, there is a gap between the indoor heat exchanger 200 and the bottom surface of the inner wall of the heat exchange chamber 131. When the condensate on the surface of the indoor heat exchanger 200 falls into the bottom of the heat exchange chamber 131 under its own gravity, the condensate can flow smoothly into the first water collection tank 132 through the gap.

[0068] Furthermore, a first guide surface 135 is provided on the bottom surface of the inner wall of the heat exchange cavity 131. The first guide surface 135 is inclined, and its bottom end is connected to the first water collection tank 132. In addition, a boss 134 is provided on the first guide surface 135.

[0069] Understandably, the condensate on the surface of the indoor heat exchanger 200 falls directly onto the first guide surface 135 under its own gravity, and then flows downward along the inclined first guide surface 135, and then flows into the first water collection tank 132.

[0070] Please see Figure 3 In some embodiments, the condensate recovery device 400 includes a fixed plate 410 and a water distributor 420.

[0071] The fixing plate 410 separates the inner cavity of the outer shell 100 to form a first chamber 110 and a second chamber 120, and the fixing plate 410 is located below the indoor heat exchanger 200.

[0072] In addition, the water distributor 420 is embedded in the fixing plate 410. The water distributor 420 is located below the first drain hole 133, and a water distribution trough 421 is provided on the water distributor 420. Multiple drain holes 422 are provided at the bottom of the water distribution trough 421.

[0073] Understandably, the fixing plate 410 is fixedly connected to the outer casing 100, while the water distributor 420 is detachably mounted on the fixing plate 410. Since the water distributor 420 is embedded in the fixing plate 410, the drain hole 422 provided on the water distributor 420 passes through the upper and lower sides of the fixing plate 410 and communicates with the first chamber 110 and the second chamber 120 respectively.

[0074] When the outdoor unit 10 is running, since the water distributor 420 is located below the first drain hole 133, the condensate flowing out of the first drain hole 133 falls into the water distributor 420 and flows into the water distribution trough 421, and is finally discharged into the second chamber 120 from the multiple drain holes 422 set at the bottom of the water distribution trough 421.

[0075] During this process, the thermal insulation material layer 130 collects condensate from the surface of the indoor heat exchanger 200 through the first guide surface 135 and the first water collection tank 132, and then discharges the condensate through the first drain hole 133. Correspondingly, the water distributor 420 receives the condensate from the first drain hole 133 and guides the condensate to flow above the outdoor heat exchanger 300 until it is discharged from multiple drain holes 422.

[0076] Understandably, in the outdoor unit 10, the outdoor heat exchanger 300 is not typically located below the indoor heat exchanger 200. Using the thermal insulation layer 130 and the water distributor 420, condensate on the surface of the indoor heat exchanger 200 can be guided downwards to the surface of the outdoor heat exchanger 300.

[0077] Please refer to the following: Figure 3 and Figure 6 In some embodiments, the water distribution trough 421 extends along the first direction, and a plurality of drain holes 422 are arranged at intervals along the first direction.

[0078] Accordingly, the outdoor heat exchanger 300 includes a first body 310. The first body 310 extends along a first direction and is located below the water distribution tank 421.

[0079] The first direction is the horizontal direction, which is represented by the X direction in the diagram.

[0080] In use, the condensate falling from the first drain hole 133 into the water distributor 420 flows into the water distribution trough 421 and is then discharged simultaneously from multiple drain holes 422. Since the first body 310 of the outdoor heat exchanger 300 is located below the water distribution trough 421 and extends in the same direction as the water distribution trough 421, the condensate can flow more evenly to the surface of the first body 310, resulting in a better cooling effect on the outdoor heat exchanger 300.

[0081] In this embodiment, the outdoor heat exchanger 300 also includes a second body 320. The second body 320 is perpendicular to the first body 310, and the entire outdoor heat exchanger 300 is L-shaped. It should be noted that the pipes in the first body 310 and the second body 320 are interconnected.

[0082] In some embodiments, the water distributor 420 is provided with a second guide surface 423. The second guide surface 423 is inclined, and its bottom end is connected to the water distribution trough 421. The second guide surface 423 is located below the first drain hole 133.

[0083] In use, the condensate flowing out of the first drain hole 133 falls directly onto the second guide surface 423, and then flows downward along the inclined second guide surface 423, and then flows into the water distribution tank 421.

[0084] Please refer to the following: Figure 2 and Figure 7 In some embodiments, a second drain hole 150 is provided at the bottom of the second chamber 120.

[0085] During use, the portion of the condensate that has not completely evaporated after cooling the outdoor heat exchanger 300 can be discharged from the second drain hole 150 to the outside of the outer casing 100, making it less likely for water to accumulate in the second chamber 120.

[0086] Furthermore, a second water collection tank 160 is provided on the bottom surface of the inner wall of the second chamber 120. The second water collection tank 160 is located below the outdoor heat exchanger 300, and a second drain hole 150 is provided at the bottom of the second water collection tank 160.

[0087] Understandably, since the second water collection tank 160 is located below the outdoor heat exchanger 300, the condensate that has not yet fully evaporated falls directly into the second water collection tank 160 under its own gravity, collects in the second water collection tank 160, and then is discharged to the outside of the outer casing 100 from the second drain hole 150 located at the bottom of the second water collection tank 160, which can better prevent water accumulation in the second chamber 120.

[0088] In summary, when the outdoor unit 10 is running, the circulating fan 500 draws indoor return air and / or fresh air into the first chamber 110, allowing the indoor return air and / or fresh air to exchange heat with the indoor heat exchanger 200, and then the cooled air is returned to the room. During this process, water vapor in the indoor return air and / or fresh air condenses into water on the surface of the indoor heat exchanger 200. The condensate falls into the bottom of the heat exchange chamber 131 under its own gravity, then flows out through the first drain hole 133 and falls into the water distributor 420, and is then discharged into the second chamber 120 through multiple drain holes 422 located at the bottom of the water distribution trough 421. Since the drain holes 422 are located above the outdoor heat exchanger 300, the condensate flows to the surface of the outdoor heat exchanger 300, cooling the outdoor heat exchanger 300, thereby improving the heat exchange efficiency of the outdoor heat exchanger 300, reducing the compressor workload, improving the overall energy efficiency, and enabling the outdoor unit 10 to continue operating at high frequency even in hot weather. Therefore, the outdoor unit 10 can make full use of condensate, resulting in greater energy savings.

[0089] This embodiment also provides an air conditioner, including the outdoor unit 10 described above.

[0090] Please see Figure 8 In some embodiments, the air conditioner also includes an indoor unit 20, a return air duct 30, and a supply air duct 40.

[0091] The indoor unit 20 and the outdoor unit 10 are respectively installed on both sides of the wall. The side of the indoor unit 20 facing the wall has a fresh air inlet 21, a return air inlet 22, and a supply air outlet 23. The return air duct 30 and the supply air duct 40 are both connected to the outdoor unit 10. The return air duct 30 is connected to the heat exchange chamber 131 through the gas inlet 141, and the supply air duct 40 is connected to the heat exchange chamber 131 through the gas outlet 142.

[0092] The fresh air inlet 21 connects to the external environment through a hole in the wall. The return air inlet 22 connects to the return air duct 30 through a connecting pipe that passes through the wall, and then connects to the heat exchange chamber 131 through the return air duct 30. The supply air inlet 23 connects to the supply air duct 40 through another connecting pipe that passes through the wall, and then connects to the heat exchange chamber 131 through the supply air duct 40.

[0093] When the air conditioner is running, the circulating fan 500 starts, driving indoor return air into the indoor unit 20, and driving outdoor fresh air introduced into the room through the fresh air inlet 21 into the indoor unit 20. After the indoor return air and fresh air mix, they flow sequentially through the return air duct 30, the gas inlet 141, and the heat exchange chamber 131, where they exchange heat with the indoor heat exchanger 200. The cooled mixed air then flows sequentially through the gas outlet 142, the air supply duct 40, and the air supply outlet 23, before flowing back into the indoor unit 20 and being discharged into the room.
