In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The following is for reference. Figures 1-5 An integrated air conditioner 100 according to an embodiment of the present invention is described.

[0033] Reference Figure 1 , Figure 2 and Figure 4 According to an embodiment of the present invention, an integrated air conditioner 100 includes a housing 1 and a compressor 2, a first heat exchanger 3, and a second heat exchanger 4 disposed within the housing 1. Both the first heat exchanger 3 and the second heat exchanger 4 are connected to the compressor 2, with one serving as a condenser and the other as an evaporator. When the integrated air conditioner 100 is in operation, the compressor 2 compresses the refrigerant and sends it to the condenser. After throttling, the refrigerant passes through the evaporator to absorb heat from the air, and then returns to the compressor 2 to continue compression, continuing the cycle.

[0034] The integrated air conditioner 100 also includes a supply fan and an exhaust fan 5 disposed in the housing 1. The supply fan is used to generate airflow to exchange heat with the first heat exchanger 3 and to supply air to the indoor side, and the exhaust fan 5 is used to generate airflow to exchange heat with the second heat exchanger 4 and to exhaust air to the outdoor side.

[0035] It should be noted that the integrated air conditioner 100 may have only a cooling mode, or both a cooling mode and a heating mode. In cooling mode, the first heat exchanger 3 acts as an evaporator and the second heat exchanger 4 acts as a condenser. When the blower is working, it causes airflow to exchange heat with the evaporator and the heat is absorbed by the evaporator, so that the blower delivers cold air to the room. In heating mode, the first heat exchanger 3 acts as a condenser and the second heat exchanger 4 acts as an evaporator. When the blower is working, it causes airflow to exchange heat with the condenser and remove the heat from the condenser, so that the blower delivers hot air to the room.

[0036] In this embodiment of the invention, the chassis of the outer shell 1 is provided with a water receiving area 10, which is located at least below the second heat exchanger 4 to collect condensate. It should be noted that the condensate falling on the second heat exchanger 4 can be condensate formed on the second heat exchanger 4, or condensate pumped onto the second heat exchanger 4 by a water pumping device; the invention does not limit this.

[0037] It should be understood that the water receiving area 10 may be located only below the second heat exchanger 4, or it may be located below both the first heat exchanger 3 and the second heat exchanger 4. A portion of the water receiving area 10 may also be located below other components of the air conditioner. In some embodiments, the integrated air conditioner 100 has a heating module. In heating mode, the second heat exchanger 4 acts as an evaporator, and the water receiving area 10 is located at least below the second heat exchanger 4, allowing it to directly collect condensate formed on the surface of the second heat exchanger 4. In some embodiments, the integrated air conditioner 100 has a cooling mode. In cooling mode, the first heat exchanger 3 acts as an evaporator, and the second heat exchanger 4 acts as a condenser. In such embodiments, a portion of the water receiving area 10 is located below the second heat exchanger 4, and another portion of the water receiving area 10 is located below the first heat exchanger 3 to collect condensate formed on the surface of the first heat exchanger 3.

[0038] In this embodiment of the invention, the exhaust fan 5 includes an air guide shell 51 and a fan wheel 52. The air guide shell 51 defines an air guide duct 511, which is provided with an air inlet area 512 and an air outlet area 513. The fan wheel 52 is located inside the air guide duct 511. When the fan wheel 52 is working, it causes airflow to exchange heat with the second heat exchanger 4 and exhaust air to the outside. During this process, after the airflow exchanges heat with the second heat exchanger 4, it enters the air guide duct 511 through the air inlet area 512 and is discharged to the outside through the air outlet area 513.

[0039] The air guide shell 51 is also provided with a water absorption area 514 located between the air inlet area 512 and the air outlet area 513. The water absorption area 514 is located above the water receiving area 10 to draw the condensate in the water receiving area 10 into the air guide duct 511.

[0040] The water absorption area 514 is located between the air inlet area 512 and the air outlet area 513. One end of the water absorption area 514 is connected to the air guide duct 511 and the other end is connected to the outside of the air guide shell 51. When the exhaust fan 5 is working, the airflow in the air guide duct 511 flows from the air inlet area 512 to the air outlet area 513. The wind speed in the air guide duct 511 is higher than the wind speed on the outside of the air guide shell 51, which causes the air pressure in the air guide duct 511 to be lower than the air pressure on the outside of the air guide shell 51. The water absorption area 514 generates suction, which can draw the condensate in the water receiving area 10 into the air guide duct 511. The condensate in the air guide duct 511 is discharged from the air outlet area 513 along with the airflow, effectively reducing the condensate in the water receiving area 10, reducing the risk of air conditioner leakage, and reducing the risk of condensate overflow affecting the electrical components in the air conditioner.

[0041] According to the integrated air conditioner 100 of the present invention, the exhaust fan 5 can not only drive the airflow to exchange heat with the second heat exchanger 4 and improve the heat exchange efficiency of the second heat exchanger 4, but also the exhaust fan 5 can extract the condensate in the water receiving area 10, reducing the risk of condensate overflow affecting the electrical components in the air conditioner, and also reducing the risk of air conditioner leakage.

[0042] In some embodiments, the exhaust fan 5 is a centrifugal fan, and the water intake area 514 is located on the radial outer side of the blades of the impeller 52.

[0043] Compared to other types of fans, centrifugal fans typically provide a larger air volume at the same power, which can improve the heat exchange efficiency of the second heat exchanger 4 and increase the suction force of the water absorption area 514, thus improving the reliability of the exhaust fan 5 in extracting condensate. Centrifugal fans operate relatively smoothly, with less vibration generated during impeller rotation. This helps reduce operating noise and create a quiet indoor environment for users. Centrifugal fans have a compact structure and occupy relatively little space. In an integrated air conditioner 100, they can be more easily installed in limited spaces, which is beneficial for the overall miniaturization and lightweight design of the product.

[0044] Furthermore, in this embodiment of the invention, the water absorption area 514 is located on the radial outer side of the blades of the impeller 52. The wind speed on the radial outer side of the blades of the impeller 52 in the centrifugal fan is usually higher, which further increases the pressure difference between the two ends of the water absorption area 514, increases the suction force of the water absorption area 514, and improves the reliability of the exhaust fan 5 in extracting condensate.

[0045] It should be understood that, in other embodiments, the water absorption area 514 may also be located in the axial direction of the impeller 52, near the air inlet area 512, near the air outlet area 513, or other locations. The present invention is not limited to this, as long as the water absorption area 514 can generate suction to absorb condensate. It should also be understood that the exhaust fan 5 is not limited to a centrifugal fan. In other embodiments, the exhaust fan 5 may also be an axial flow fan, a cross-flow fan, or other fans. The present invention is not limited to this.

[0046] In some embodiments, the water absorption area 514 is located at the bottom of the air duct 511, which helps to reduce the distance between the water absorption area 514 and the condensate, and improves the reliability of the water absorption area 514 in extracting condensate.

[0047] In some specific embodiments, the exhaust fan 5 is a centrifugal fan, and the water suction area 514 is located on the radially outer side of the blades of the impeller 52. The water suction area 514 is located at the bottom of the air guide duct 511.

[0048] When the exhaust fan 5 is working, the blades of the impeller 52 rotate clockwise, and the airflow between the radially outer side of the impeller 52 blades and the inner wall of the air duct 511 also flows clockwise to the outlet area 513 for discharge. After the water absorption area 514 draws condensate into the air duct 511, the water droplets are pressed by the airflow between the radially outer side of the impeller 52 and the inner wall of the air duct 511 and flow clockwise along the inner wall of the air duct 511 to the outlet area 513 for discharge. In order to ensure that the water droplets can flow clockwise along the inner wall of the air duct 511, the airflow between the radially outer side of the impeller 52 and the inner wall of the air duct 511 needs to have a high wind speed. Preferably, the rotational speed of the impeller 52 is not less than 900 r / min.

[0049] The above technical solution enables condensate to flow smoothly from the air duct 511 to the air outlet area 513, reducing the risk of condensate affecting the normal operation of the exhaust fan 5 and improving the reliability of the exhaust fan 5 in extracting condensate.

[0050] Reference Figure 4 In some embodiments, the integrated air conditioner 100 also includes a water diffuser 6, which is used to collide with the condensate drawn out by the exhaust fan 5 to disperse the condensate.

[0051] Through the above technical solution, the condensate can be dispersed into several small water droplets after colliding with the water diffuser 6, which is conducive to the evaporation of condensate and reduces the possibility of water dripping in the air outlet area 513.

[0052] In some embodiments, the water distribution element 6 is formed as a mesh structure.

[0053] In this embodiment of the invention, the structure of the water distribution component 6 is simple, easy to manufacture, and reduces costs. In addition, the large area of ​​the mesh structure increases the probability of condensate colliding with the water distribution component 6, while also reducing the impact on the wind speed of the exhaust fan 5, thus ensuring the reliability of the integrated air conditioner 100.

[0054] In some embodiments, the water diffuser 6 is disposed within the exhaust fan 5 and located in the air outlet area 513.

[0055] The above technical solution further increases the probability of condensate colliding with the water distribution component 6, reduces the risk of water distribution component 6 interfering with external objects, and reduces the risk of external objects entering the air duct 511 through the air outlet area 513 and affecting the rotation of the fan wheel 52 by blocking the water distribution component 6, thereby improving the reliability of the integrated air conditioner 100.

[0056] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, the water receiving area 10 includes a first water receiving tank 11 and a water storage tank 12 located below the second heat exchanger 4, the water storage tank 12 being connected to the first water receiving tank 11 and located directly below the exhaust fan 5.

[0057] In this embodiment of the invention, the first water receiving tank 11 is located below the second heat exchanger 4 to collect the condensate falling from the second heat exchanger 4. The water storage tank 12 is connected to the first water receiving tank 11. The condensate in the first water receiving tank 11 can flow to the water storage tank 12 and then be drawn out by the exhaust fan 5 above the water storage tank 12.

[0058] In this embodiment of the invention, the water receiving area 10 includes a water storage tank 12 located directly below the exhaust fan 5, which further improves the reliability of the exhaust fan 5 in extracting condensate.

[0059] In some embodiments, the distance between the water absorption area 514 and the bottom wall of the water storage tank 12 is H, where 5mm ≤ H ≤ 10mm.

[0060] If H is less than 5mm, the water in the water storage tank 12 can easily flow directly into the air duct 511. Too much liquid in the air duct 511 can easily affect the normal operation of the exhaust fan 5. If H is greater than 10mm, the water absorption area 514 will have difficulty absorbing the condensate in the water storage tank 12.

[0061] In this embodiment of the invention, 5mm≤H≤10mm will not result in too much liquid in the air duct 511, and will also ensure the reliability of the water absorption area 514 in absorbing condensate.

[0062] In some specific embodiments, the distance H between the water absorption area 514 and the bottom wall of the water storage tank 12 can be any one of 5mm, 7mm, 8mm, 10mm or any range between two.

[0063] In some specific embodiments, the water absorption area 514 includes a plurality of spaced water absorption holes. The structure of the water absorption area 514 in the embodiments of the present invention is simple, and the water absorption holes can easily concentrate the suction force, ensuring the reliability of the water absorption area 514 in absorbing condensate.

[0064] In some embodiments, the water receiving area 10 further includes a water pumping component 7, which is movably disposed on the first water receiving tank 11 for pumping condensate toward the second heat exchanger 4.

[0065] When the integrated air conditioner 100 is in cooling mode, the water pumping component 7 operates to pump condensate onto the second heat exchanger 4. The condensate absorbs the heat emitted by the second heat exchanger 4, which helps to improve the heat exchange efficiency of the second heat exchanger 4 and improve the cooling effect of the integrated air conditioner 100.

[0066] In some specific embodiments, the water pumping component 7 includes a water pumping motor and a water pumping wheel installed on the water pumping motor. The bottom of the first water receiving tank 11 is provided with an inclined angle so that the condensate in the first water receiving tank 11 gathers below the water pumping wheel, which makes it easier for the water pumping motor to drive the water pumping wheel to pump the condensate onto the second heat exchanger 4, thereby improving the heat exchange efficiency of the second heat exchanger 4.

[0067] Reference Figure 3 , Figure 4 and Figure 4 In some embodiments, the water receiving area 10 further includes a first water tank 13, which is located between the first water receiving tank 11 and the water storage tank 12. At least a portion of the first water tank 13 is located below the second heat exchanger 4 for receiving condensate. The first water tank 13 is provided with a first overflow port 131, and the first water tank 13 is connected to the water storage tank 12 through the first overflow port 131.

[0068] When the condensate forms slowly, there is less water in the first water receiving tank 11. The water pumping component 7 pumps the condensate to the second heat exchanger 4. Some of the condensate is evaporated by the heat emitted by the second heat exchanger 4, while the condensate that is not evaporated falls back into the first water receiving tank 11. As the water pumping component 7 continues to work, the liquid level in the first water receiving tank 11 decreases or increases slowly.

[0069] When the condensate forms quickly, there is more water in the first water tank 11. When the water pumping device 7 works, it will pump more condensate towards the second heat exchanger 4. More condensate will fall down from the second heat exchanger 4 without being evaporated. Some of the falling condensate will fall into the first water tank 13.

[0070] By collecting some of the condensate in the first water tank 13, the liquid level in the first water receiving tank 11 can be reduced. Furthermore, when the liquid in the first water tank 13 reaches a certain height, the water in the first water tank 13 can flow through the first overflow port 131 to the water storage tank 12, and then be drawn out by the exhaust fan 5, reducing the risk of air conditioner leakage.

[0071] In some embodiments, the water receiving area 10 further includes a second water receiving tank 14, which is located below the first heat exchanger 3 and is connected to the first water receiving tank 11 through the flow guiding area 15.

[0072] In cooling mode, the first heat exchanger 3 acts as an evaporator and the second heat exchanger 4 acts as a condenser. The condensate formed on the first heat exchanger 3 falls into the second water receiving tank 14, and then flows through the guide area 15 to the first water receiving tank 11. It is then sprayed by the water spraying component 7 to the second heat exchanger 4, thereby improving the heat exchange efficiency of the second heat exchanger 4.

[0073] In some specific embodiments, the bottom wall of the first water receiving tank 11 is lower than the bottom wall of the second water receiving tank 14, so that the condensate in the second water receiving tank 14 can flow to the first water receiving tank 11. The water will flow to the lower-positioned first water receiving tank 11 first, and the coldest water will be pumped onto the second heat exchanger 4 as soon as possible, which can maximize the use of low-temperature condensate and improve heat exchange efficiency.

[0074] In some further embodiments, the bottom wall of the second water receiving tank 14 is provided with an inclined surface extending toward the first water receiving tank 11. The condensate generated by the first heat exchanger 3 flows to the bottom of the second heat exchanger 4. The water after exchanging heat with the second heat exchanger 4 cannot flow back to the bottom of the first heat exchanger 3 in the opposite direction. The water path between the first water receiving tank 11 and the second water receiving tank 14 is a unidirectional water path, which can avoid the problem of the hot water after heat exchange affecting the temperature of the first heat exchanger 3 and thus reducing the heat exchange efficiency.

[0075] In some specific embodiments, the slope of the bottom wall of the second water receiving tank 14 is 0.1 to 3 degrees relative to the horizontal plane to meet the requirements of water flow by gravity.

[0076] In some embodiments, the second water receiving tank 14 is provided with a support rib 141 for supporting the first heat exchanger 3. The support rib 141 extends upward from the bottom wall of the second water receiving tank 14 to facilitate the installation of the first heat exchanger 3 and to facilitate the second water receiving tank 14 to collect the condensate falling from the first heat exchanger 3.

[0077] In some embodiments, the first water tank 13 is provided with an outlet 132 communicating with the flow guiding area 15, and the first overflow outlet 131 is higher than the outlet 132.

[0078] When the liquid level in the first water tank 13 rises to the outlet 132, the water in the first water tank 13 flows to the guide area 15. When the liquid level in the first water tank 13 rises to the first overflow outlet 131, it means that the liquid levels in the first water receiving tank 11 and the guide area 15 have both risen to a high position. The water in the first water tank 13 cannot be discharged directly through the outlet 132. At this time, it can flow to the water storage tank 12 through the first overflow outlet 131 and then be drawn out by the exhaust fan 5, reducing the risk of air conditioner leakage.

[0079] In some embodiments, a portion of the first water tank 13 extends away from the first water receiving tank 11, and an outlet 132 is provided at the end of the first water tank 13 away from the first water receiving tank 11.

[0080] When the liquid level in the first water tank 13 rises to the outlet 132, the water in the first water tank 13 flows to the guide area 15, and then flows to the first receiving tank 11 through the guide area 15. By setting the outlet 132 at a position far away from the first receiving tank 11, the path of the water in the first water tank 13 flowing back to the first receiving tank 11 is extended, and the speed at which the liquid level in the first receiving tank 11 rises is slowed down.

[0081] In some embodiments, the outlet 132 is 3mm to 25mm higher than the bottom wall of the guide area 15, which can prevent water from flowing into the first water tank 13 when the water level is low, and ensure that the water in the second water tank 14 preferentially enters the first water tank 11.

[0082] In some embodiments, the flow guiding area 15 is provided with a drain outlet 151, and a removable sealing element is provided at the drain outlet 151.

[0083] With the above technical solution, when repairing the integrated air conditioner 100, the sealing part can be removed to drain the water in the water inlet area 10, thus preventing water from flowing into the electrical control or the user's home during the disassembly process.

[0084] In some embodiments, the bottom wall of the flow guiding area 15 is lower than the bottom wall of the first water receiving tank 11.

[0085] With the above technical solution, after the sealing part is removed, the condensate in the first water tank 11 can also flow to the drain outlet 151 for discharge, which is convenient for maintenance.

[0086] In some specific embodiments, the bottom wall of the flow guiding area 15 is 0.5mm to 10mm lower than the bottom wall of the first water receiving tank 11.

[0087] It should be noted that the drop between the bottom wall of the flow guiding area 15 and the bottom wall of the first water receiving tank 11 can be a sloping transition or a stepped drop, and the present invention does not limit this.

[0088] In some specific embodiments, the bottom wall of the diversion area 15 is located at the lowest point of the water receiving area 10 so that all water in the water receiving area 10 is discharged through the drain outlet 151.

[0089] In some embodiments, the water receiving area 10 further includes a second water tank 16, the second water tank 16 and the water storage tank 12 are located on different sides of the first water receiving tank 11, and the first water receiving tank 11 is connected to the second water tank 16 through a second overflow port.

[0090] If the exhaust fan 5 cannot extract the condensate in time, causing the condensate to rise continuously, the condensate can enter the second water tank 16 when it rises to the second overflow port, further reducing the risk of condensate overflowing directly.

[0091] In some embodiments, the bottom wall of the second water tank 16 is 0.5 mm to 10 mm higher than the bottom wall of the first water receiving tank 11, so that when the water level drops, the water in the second water tank 16 flows back to the first water receiving tank 11.

[0092] It should be noted that the drop between the bottom wall of the second water tank 16 and the bottom wall of the first water receiving tank 11 can be a slope transition or a stepped drop, and the present invention does not limit this.

[0093] In some embodiments, the integrated air conditioner 100 further includes a control module and a water level detection element 8. The control module is connected to the compressor 2 to control the operating state of the compressor 2. The water level detection element 8 is used to detect the liquid level in the second water tank 16. The water level detection element 8 is connected to the control module. When the water level detection element 8 detects that the water level in the second water tank 16 is higher than a first set height, the control module controls the compressor 2 to stop working or reduce its frequency.

[0094] As the water level continues to rise, the increased condensate will flow along the second water tank 16 to the water level detection element 8. The control module can control the water level by reducing the wind speed of the blower, reducing the frequency of the compressor 2, or stopping the operation of the compressor 2.

[0095] The above technical solution can slow down the formation rate of condensate on the evaporator, prevent the continuous rise of condensate, and further reduce the risk of air conditioner leakage.

[0096] In some embodiments, the integrated air conditioner 100 is suitable for embedded installation, such as in a relatively enclosed space like a ceiling, under a workbench, or embedded in a cabinet. By adopting the solution proposed in this invention, the risk of the first heat exchanger 3 or the second heat exchanger 4 being submerged in water is reduced, the risk of water leakage from the integrated air conditioner 100 is reduced, and the operational reliability of the integrated air conditioner 100 is improved.

[0097] In some embodiments, a water pump may be provided in the second water receiving tank 14 or the flow guiding area 15 to accelerate the flow of condensate.

[0098] In some further embodiments, for kitchen environments, a filter module can be added along with a water pump. For example, a water pump and a filter module are provided in the flow guide area 15. The water pump pumps condensate water containing grease into the filter module. The filtered water flows through a water pipe to the first water receiving tank 11 and is then agitated by the water pumping component 7.

[0099] The above technical solution reduces the risk of the second heat exchanger 4 being contaminated by grease and ensures the heat exchange efficiency of the second heat exchanger 4 and the airflow.

[0100] Other configurations of the integrated air conditioner 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
