The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0048] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0050] This application relates to integrated air conditioning systems, such as kitchen air conditioners and portable air conditioners. These integrated air conditioners can also have humidification and dehumidification functions, allowing them to be used as humidifiers and dehumidifiers.

[0051] To address the problem of low heat exchange efficiency and low energy efficiency caused by the limited area of ​​the internal water pumping motor to pump water to the condenser in integrated air conditioners, a new integrated air conditioner is proposed.

[0052] The following description uses a portable air conditioner as an example, but this application is not limited to this.

[0053] like Figure 1 , 3 As shown in Figure 4, this application provides an integrated air conditioner, including a housing (not shown) and a heat exchange assembly, an intermediate water tray 3, a first water pumping assembly 4, and a bottom water receiving tray disposed in the housing. 11 The second water-discharging assembly 12 includes a heat exchange assembly comprising an evaporator 10 and a condenser, with the condenser located below the evaporator 10. The condenser comprises an upper condenser 1 and a lower condenser 2 arranged vertically. An intermediate water-discharging tray 3 is disposed between the upper condenser 1 and the lower condenser 2, and is used to collect condensate dripping from the evaporator 10 and supply some of the condensate to the lower condenser 2. A bottom water-discharging tray 11 is used to directly or indirectly collect condensate supplied from the intermediate water-discharging tray 3 to the lower condenser 2. A first water-discharging assembly 4 is used to discharge the condensate collected in the intermediate water-discharging tray 3 to the upper condenser 1. A second water-discharging assembly 12 is used to discharge the condensate collected in the bottom water-discharging tray 11 to the lower condenser 2.

[0054] It is worth noting that in related technologies, when one water-pumping component pumps water to one condenser, the water-pumping blind zone of the condenser is large due to the limitation of the water-pumping height of the component, resulting in low heat exchange efficiency. In this embodiment, two water-pumping components pump the condensate in the middle water tray 3 and the condensate in the bottom water tray 11 to the upper condenser 1 and the lower condenser 2, respectively. Compared with one water-pumping component pumping water to one condenser, the condenser includes an upper condenser 1 and a lower condenser 2 arranged vertically. This eliminates the limitation of the water-pumping height of the components without reducing the overall height of the condenser, thereby reducing the water-pumping blind zone of the upper condenser 1 and the lower condenser 2 and improving heat exchange efficiency.

[0055] The condensate dripping from the evaporator 10 drips onto the upper condenser 1 and then onto the middle drain pan 3. The condensate generated by the evaporator 10 is pumped to the upper condenser 1 and / or the lower condenser 2 by the water pumping assembly, so that the middle drain pan 3 indirectly receives the condensate dripping from the evaporator 10; and / or, the condensate dripping from the middle drain pan 3 drips onto the lower condenser 2 and then onto the bottom drain pan 11, so that the bottom drain pan 11 indirectly receives the condensate dripping from the middle drain pan 3.

[0056] The intermediate drain pan 3 can directly collect condensate dripping from the evaporator 10 or indirectly collect condensate dripping from the evaporator 20. In the case where the intermediate drain pan 3 directly collects condensate dripping from the evaporator 10, the condensate dripping from the evaporator 10 drips directly into the intermediate drain pan 3 without passing through the upper condenser 1. In the case where the intermediate drain pan 3 indirectly collects condensate dripping from the evaporator 20, the condensate dripping from the evaporator 10 first drips into the upper condenser 1 and then into the intermediate drain pan 3.

[0057] Similarly, the bottom drip tray 11 can also directly or indirectly receive condensate dripping from the middle drip tray 3. In the case where the bottom drip tray 11 directly receives condensate dripping from the middle drip tray 3, the condensate dripping from the middle drip tray 3 drips directly into the bottom drip tray 11 without passing through the lower condenser 2; in the case where the bottom drip tray 11 indirectly receives condensate dripping from the middle drip tray 3, the condensate dripping from the middle drip tray 3 first passes through the lower condenser 2 before dripping into the bottom drip tray 11.

[0058] In the case where condensate drips from the intermediate drain pan 3 to the lower condenser, the overall air conditioner can preferably be equipped with a water distribution device with a multi-hole spray / drip surface. The multi-hole plate of the water distribution device will evenly drip or spray the water from the drain area 6 to the lower condenser 2, thereby further improving the heat exchange efficiency.

[0059] The bottom drip tray 11 can be part of the housing; for example, the bottom wall of the housing may have a water storage space to directly or indirectly collect condensate dripping from the middle drip tray 3. Alternatively, the bottom drip tray 11 can be a separate component, located within the housing, to directly or indirectly collect condensate dripping from the middle drip tray 3. This combined upper and lower water pumping method increases the heat exchange area of ​​the condenser, improving the heat exchange efficiency of the upper and lower condensers working together, thereby enhancing the overall energy efficiency of the air conditioner.

[0060] Combination Figure 2Preferably, the intermediate water tray 3 forms a water storage area 5 and a drainage area 6. The water storage area 5 is used to collect condensate dripping from the upper condenser 1, and the drainage area 6 is used to guide the condensate overflowing from the water storage area 5 and / or the condensate dripping from the intermediate water tray 3 onto the upper condenser 1 to the lower condenser 2. The water storage area 5 is provided with a water inlet corresponding to the upper condenser 1, and the drainage area 6 is provided with a drain outlet corresponding to the lower condenser 2. Preferably, an overflow outlet is provided between the water storage area 5 and the drainage area 6. The overflow outlet is located above or equal to the lowest water level in the water storage area 5, and the drain outlet is located below the overflow outlet. This ensures that the water storage area 5 of the intermediate water tray 3 has a water level that meets the requirements of the first water pumping component 4, and that the water level is neither too high nor too low. The simple overflow outlet design can fully ensure the safety of the water pumping motor and avoid unnecessary energy consumption.

[0061] The intermediate water tray 3 is preferably made of metal. The bottom of the upper condenser 1 contacts the upper surface of the intermediate water tray 3 and is supported on the intermediate water tray 3. The top of the lower condenser 2 contacts the lower surface of the intermediate water tray 3. In this way, the thermal conductivity of the intermediate water tray 3 can be used to conduct heat dissipation between the upper and lower condensers.

[0062] Preferably, the intermediate water tray 3 is provided with water-retaining ribs 7, which divide the intermediate water tray 3 into a water storage area 5 and a drainage area 6 separated from each other. The upper condenser 1 is partially located above the drainage area 6, so that the condensate from the water storage area 5 to the upper condenser 1 is discharged through the drainage area 6 and drips to the lower condenser 2. Preferably, the intermediate water tray 3 is provided with a drain outlet located in the drainage area 6, and the portion of the water-retaining ribs 7 surrounding the drain outlet forms the drainage area 6. The height of the water-retaining ribs 7 is lower than the height of the peripheral wall of the intermediate water tray 3. The upper condenser 1 is at least partially supported on the water-retaining ribs 7. In addition, the water-retaining ribs 7 divide the intermediate water tray 3 into a water storage area 5 and a drainage area 6, and multiple water-retaining ribs 7 form a drain outlet in the intermediate water tray 3, so that water does not flow directly out of the drain outlet, which facilitates water storage in the water storage area 5. Preferably, the intermediate water tray 3 is further provided with a water guide rib 9 extending from the water storage area 5 to the drainage area 6. Preferably, the height of the water guide rib 9 on the drainage area side is higher than its height on the water storage area side, so that the water level in the water guide rib 9 that guides the water that has not flowed down back to the water storage area 5 can ensure the operation of the water pump. Preferably, the upper condenser 1 is partially supported on the water baffle rib 7 and partially supported on the water guide rib 9. On the one hand, this realizes the supporting capacity of the intermediate water tray 3, reduces the burden on the split structure, and increases the overall structural strength; on the other hand, a certain flow channel is formed between the bottom of the upper condenser and the intermediate water tray, which can facilitate the passage of both air and water. In addition, the water baffle rib 7 and the water guide rib 9 can jointly support the upper condenser.

[0063] Preferably, a water inlet pipe and a water pump are connected between the bottom water receiving tray 11 and the middle water receiving tray 3 to pump water from the bottom water receiving tray 11 back to the middle water receiving tray 3; a water inlet valve is provided on the water inlet pipe. Preferably, a drain pipe is also connected between the bottom water receiving tray 11 and the middle water receiving tray 3, with one end of the drain pipe connected to the water storage space of the bottom water receiving tray 11 and the other end connected to the drainage area 6 of the middle water receiving tray 3. ， A drain valve is installed on the drain pipe.

[0064] Preferably, the first water-spraying assembly 4 includes a first water-spraying motor and a first water-spraying flywheel 42 disposed on the output shaft of the first water-spraying motor. The first water-spraying flywheel 42 is disposed in the intermediate water receiving pan 3 and is used to spray the condensate collected in the intermediate water receiving pan 3 onto the upper condenser 1. The second water-spraying assembly 12 includes a second water-spraying motor and a second water-spraying flywheel 121 disposed on the output shaft of the second water-spraying motor. The second water-spraying flywheel 121 is disposed in the bottom water receiving pan 11 and is used to spray the condensate in the bottom water receiving pan 11 onto the lower condenser 2.

[0065] Specifically, the intermediate water tray 3 is equipped with a support for supporting the first water-operating assembly 4. The intermediate water tray 3 also includes a first water-operating motor position 41, which can also fix the first water-operating motor to the housing or volute. This design not only saves costs but also saves space, making the overall air conditioning system simpler and more convenient.

[0066] Preferably, the upper condenser 1 includes a first upper condenser 11 and a second upper condenser 12 arranged side by side, with a first gap between the first upper condenser 11 and the second upper condenser 12; a first water-pumping flywheel 42 is located in the first gap, so that the first water-pumping flywheel 42 pumps the condensate in the water storage area 5 toward the side of at least one of the first upper condenser 11 and the second upper condenser 12; and / or the lower condenser 2 includes a first lower condenser 21 and a second lower condenser 22 arranged side by side, the first lower condenser 21 and the second lower condenser 22 are disposed on the bottom water receiving tray 11, with a second gap between them; a second water-pumping flywheel 121 is located in the second gap, so that the second water-pumping flywheel 121 pumps the condensate in the bottom water receiving tray 11 toward the side of at least one of the first lower condenser 21 and the second lower condenser 22, thereby improving water pumping efficiency, increasing water pumping area, reducing water pumping blind zone, and improving heat exchange efficiency.

[0067] As a further preferred embodiment of this application, a water inlet pipe and a water pump are connected between the bottom water receiving tray 11 and the middle water receiving tray 3 to pump water from the bottom water receiving tray 11 back to the middle water receiving tray 3. A drain pipe is also connected between the bottom water receiving tray 11 and the middle water receiving tray 3, with one end of the drain pipe connected to the water storage space of the bottom water receiving tray 11 and the other end connected to the drainage area of ​​the middle water receiving tray 3. More preferably, the inlet pipe and / or the drain pipe are equipped with a water inlet valve, thereby allowing for water volume adjustment based on the water levels in the upper and lower water receiving trays to ensure effective water pumping.

[0068] Furthermore, in addition to the above-described structure, the overall air conditioner also includes an air duct assembly and a compressor 13 disposed within the housing. The air duct assembly includes a volute and a fan disposed within the volute. The volute includes a first air duct and a second air duct. The first air duct includes a first air intake and a first air outlet. The second air duct includes a second air intake and a second air outlet. The compressor 13 is connected to the evaporator 10 and the condenser. The housing includes a first air inlet corresponding to the first air intake, a second air inlet corresponding to the second air intake, a first air outlet corresponding to the first air outlet, and a second air outlet corresponding to the second air outlet. The evaporator 10 is located between the first air inlet and the first air intake.

[0069] The integrated air conditioner transforms the existing one-piece condenser into a stacked, separate condenser, adding a middle drain pan 3 between the two and a bottom drain pan 11 at the bottom of both. This allows the present application to reduce the water pumping blind zone caused by insufficient flywheel head without increasing the condenser height, thus simply and efficiently improving the condenser's heat exchange efficiency. Furthermore, the upper and lower condensers are each made into two separate structures arranged side-by-side, with the corresponding flywheel positioned between the two parallel condensers. This further reduces the water pumping blind zone, improves water pumping efficiency, and comprehensively enhances the heat exchange effect, reducing the condenser subcooling by at least 1.5°C, increasing the cooling capacity by at least 1.3%, and improving energy efficiency by at least 1.5%.
