Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, specifically to an integrated air conditioner. Background Technology

[0002] With the development of society and economy and the improvement of people's living standards, air conditioners have become an indispensable electrical appliance in daily work and life. While pursuing a comfortable temperature environment, energy conservation and consumption reduction have also become important directions for the development of air conditioning technology.

[0003] During air conditioning cooling operation, the evaporator on the indoor side cools and dehumidifies the flowing hot and humid air, producing a large amount of condensate. In traditional air conditioning designs, whether split-type or integrated, this condensate is typically treated as waste liquid and discharged directly into the outdoor or building drainage system via drain pipes. This approach not only wastes water resources but, more importantly, ignores the cooling value inherent in the condensate itself. Effectively utilizing this low-temperature condensate would significantly improve the energy efficiency of air conditioning systems.

[0004] In particular, for integrated air conditioners (such as window air conditioners and portable air conditioners), their structural feature is that the evaporator and condenser are compactly integrated into a single unit. This structure limits the application of the technology used in traditional split air conditioners, which involves channeling condensate from the indoor unit to the outdoor unit's condenser over a long distance for cooling. In integrated air conditioners, the reuse of condensate faces the following inherent challenges: Space constraints: The internal space of the machine is small and the layout is compact, making it difficult to accommodate complex and lengthy condensate delivery pipelines.

[0005] Drainage efficiency: The amount of condensate produced is limited and unstable. The core challenge of achieving effective cooling is to ensure that the condensate is delivered accurately and stably to the key heat dissipation parts of the condenser without relying on additional power (such as a water pump) and with only a simple structure, rather than dripping ineffectively.

[0006] System interference risk: The internal airflow field of the all-in-one unit is complex. Unreasonable condensate distribution or splashing may cause water mist to be carried to the indoor side by the fan, causing discomfort, or corroding the electrical components in the air duct, affecting the reliability and lifespan of the whole unit.

[0007] Therefore, existing integrated air conditioners have significant shortcomings in condensate utilization, failing to effectively use this cooling capacity to improve their energy efficiency. There is an urgent need in this field for an innovative integrated air conditioner structural design that can fully utilize its compact internal space and, through a simple and reliable physical structure, achieve efficient and safe cooling of the condenser by condensate, thereby solving the long-standing technical dilemma of wasted condensate cooling capacity in integrated air conditioners. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated air conditioner that can efficiently and reliably use the condensate produced by the evaporator to cool the condenser without introducing complex external piping, thereby improving the overall energy efficiency.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: An integrated air conditioner includes a body, an evaporator and a condenser disposed within the body, a drip tray for collecting condensate is provided below the evaporator, and a water outlet facing the condenser is provided on the drip tray. The water outlet is at a higher level than the bottom surface of the condenser, so that the condensate flowing out of the water outlet can flow to at least a portion of the heat dissipation surface of the condenser under the action of gravity.

[0010] In the aforementioned integrated air conditioner, the water receiving tray includes a connected water receiving trough and a water collection channel. The water receiving trough is located directly below the evaporator, and the projection of the evaporator on the horizontal plane is located within the water receiving trough. The water outlet is located on the side of the water collection channel near the condenser.

[0011] In the aforementioned integrated air conditioner, two air ducts are arranged side by side and spaced apart between the evaporator and the condenser. One air duct blows towards the evaporator, and the other air duct blows towards the condenser. The water collection channel passes through the space between the two air ducts.

[0012] In the aforementioned integrated air conditioner, the water outlet has a guide slope that is inclined downward toward the condenser.

[0013] In the aforementioned integrated air conditioner, the minimum distance between the water outlet and the condenser is 2-2.5 mm.

[0014] In the aforementioned integrated air conditioner, a water tray is provided at the bottom of the unit, and the projection of the condenser on the horizontal plane is at least partially located within the water tray. A rotating water-spinning plate is provided inside the water tray to throw the condensate collected in the water tray toward the condenser.

[0015] In the aforementioned integrated air conditioner, the condenser and the rear panel of the unit form a gap along the width of the unit. The water-spraying tray is set corresponding to the gap, so that part of the condensate water is directly delivered to the condenser, and the other part is splashed onto the condenser through the rear panel.

[0016] In the aforementioned integrated air conditioner, the water-spraying tray is at least partially located within the gap; or, the water-spraying tray is disposed on the side of the gap.

[0017] In the aforementioned integrated air conditioner, the rotation axis of the water-spraying tray is located near one edge of the condenser.

[0018] In the aforementioned integrated air conditioner, the water-spraying tray includes a tray body and multiple water-spraying blades. The water-spraying blades include a first blade group disposed on a first side along the axial direction of the tray body and a second blade group disposed on a second side along the axial direction of the tray body. The thickness of the water-spraying blades gradually decreases from the center of the tray body towards the outer periphery.

[0019] Compared with the prior art, the advantages of this utility model are: By positioning the water outlet above the bottom of the condenser, the condensate produced by the evaporator is collected in a drip tray and flows to the condenser, cooling it. The outlet's location allows for gravity-driven flow, eliminating the need for external power components. This design effectively addresses the limitations of compact spaces and complex, long-distance management inherent in integrated air conditioning systems. Since there is no additional power source, and the condensate generated during air conditioning operation is automatically and continuously guided to the condenser's heat dissipation surface through the drip tray, basic energy efficiency is improved. Furthermore, this system introduces virtually no additional points of failure, boasts a robust structure, a lifespan consistent with the entire unit, and extremely low maintenance costs.

[0020] Furthermore, the water receiving tray includes a connected water receiving trough and a water collecting channel. The water receiving trough is located directly below the evaporator, and the projection of the evaporator on the horizontal plane lies within the water receiving trough. The water outlet is located on the side of the water collecting channel near the condenser. The structure of the water receiving tray quickly collects water scattered over a large area of ​​the water receiving trough into the water collecting channel. This not only accelerates the movement of water towards the water outlet and avoids stagnation and evaporation losses that may occur when water flows in a wide and shallow trough, but also provides a stable flow path for the water, ensuring the continuity and stability of the water flow at the water outlet.

[0021] Furthermore, two air ducts are arranged side-by-side and spaced apart between the evaporator and the condenser. One air duct blows towards the evaporator, and the other air duct blows towards the condenser. The water collection channel passes between the two air ducts. This resolves the layout conflict between the air duct system and the condensate system in a compact space. Through structural integration, functional synergy and space saving are achieved, thereby ensuring optimal ventilation while optimizing the condensate drainage path.

[0022] Furthermore, the outlet has a guide slope that slopes downward toward the condenser. The guide slope provides a defined initial direction for the water flow, enabling it to acquire a horizontal velocity component pointing toward the condenser the instant it leaves the outlet. This ensures that the condensate water can accurately fly toward the predetermined condenser heat dissipation area, greatly improving the accuracy and reliability of the hit.

[0023] Furthermore, the minimum distance between the water outlet and the condenser is 2-2.5 mm. This distance ensures that the condensate flowing from the outlet can land stably and accurately on the condenser's heat dissipation fins under the influence of gravity, with minimal horizontal deviation and energy loss. Too large a distance will cause the water to scatter and land inaccurately; too small a distance may cause the water tray to collide with the condenser, and also requires excessively high assembly precision, which is detrimental to assembly line production.

[0024] Furthermore, a water-collecting tray is provided at the bottom of the unit, and the projection of the condenser on the horizontal plane is at least partially located within the water-collecting tray. A rotating water-spinning plate is installed within the water-collecting tray to throw the collected condensate towards the condenser. The water-collecting tray can recover unevaporated condensate, and the water-spinning plate reuses the condensate, thus achieving a closed-loop cycle of water resource utilization for the entire system and maximizing the potential for water-saving cooling.

[0025] Furthermore, a gap is formed between the condenser and the rear panel of the casing along the width of the casing. The water-spraying tray is positioned corresponding to this gap, allowing part of the condensate to directly reach the condenser, while the other part is splashed onto the condenser via the rear panel. Some water droplets impact the condenser fins with maximum kinetic energy, achieving immediate and efficient evaporation and heat absorption. The other part of the water droplets, after impacting the large rear panel, is further broken into a finer mist, which is then reflected and covers the condenser, ensuring maximum and uniform wetting of the condenser's heat dissipation area.

[0026] Furthermore, the water-spraying tray is at least partially located within the gap; or, the water-spraying tray is disposed to the side of the gap. The specific location of the water-spraying tray can be freely selected according to the internal space of the integrated air conditioner, reducing the stringent requirements for manufacturing and assembly.

[0027] Furthermore, the rotation axis of the water-spinning disc is positioned near one edge of the condenser. This causes most of the water droplets generated when the water-spinning disc rotates to move in a fan-shaped area facing the condenser body, creating a unidirectional fan-shaped water curtain with a larger sweeping area.

[0028] Furthermore, the water-spinning tray includes a tray body and multiple water-spinning blades. The water-spinning blades include a first blade group disposed on a first side along the axial direction of the tray body and a second blade group disposed on a second side along the axial direction of the tray body. The thickness of the water-spinning blades gradually decreases from the center of the tray body towards the outer periphery. By setting blade groups on the first and second sides respectively, it transforms a single rotating tray into two independent liquid distributors. One rotating component can simultaneously perform two tasks: directly splashing water onto the condenser for primary cooling, and splashing water onto the rear back plate to generate a spray mist for auxiliary cooling.

Detailed Implementation

[0031] An integrated air conditioner includes a body 100, an evaporator 200 and a condenser 300 disposed within the body 100. A drip tray 400 for collecting condensate is provided below the evaporator 200. The drip tray 400 is provided with a water outlet 410 facing the condenser 300. The horizontal height of the water outlet 410 is higher than the bottom surface of the condenser 300, so that the condensate flowing out of the water outlet 410 can flow to at least a portion of the heat dissipation surface of the condenser 300 under the action of gravity.

[0032] By positioning the water outlet 410 above the bottom surface of the condenser 300, the condensate produced by the evaporator 200 is collected by the water collection pan 400 and flows to the condenser 300, thus cooling the condenser 300. The placement of the water outlet 410 allows for gravity-driven flow without the need for additional power components, effectively addressing the limitations of compact spaces and complex long-distance management in integrated air conditioning systems. Since there is no additional power source, and the condensate inevitably generated during air conditioning operation is automatically and continuously guided through the water outlet 410 of the water collection pan 400 to the heat dissipation surface of the condenser 300, basic energy efficiency is improved. Furthermore, this system introduces virtually no additional points of failure, has a robust structure, a lifespan consistent with the entire unit, and extremely low maintenance costs.

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. 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 utility model 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 utility model.

[0035] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," 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, an electrical connection, or a connection that allows communication between them; 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, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] See Figures 1 to 11 This is an embodiment of the integrated air conditioner of the present invention. The integrated air conditioner includes a body 100, an evaporator 200 and a condenser 300 disposed within the body 100. The body 100 is generally a cuboid frame structure. A baffle is provided outside the frame to form the outer plate of the body 100 (not shown in the figure). The evaporator 200 is disposed inside the body 100 facing the front, and the condenser 300 is disposed inside the body 100 facing the rear. Between the evaporator 200 and the condenser 300, there are air ducts 500 facing the evaporator 200 and the condenser 300 respectively, which blow cold air outward and assist the condenser 300 in heat dissipation. A partition plate 600 is provided inside the body 100. The partition plate 600 separates the evaporator 200 and its corresponding air duct 500 and the condenser 300 and its corresponding air duct 500 inside the body 100, so as to prevent the evaporator 200 and the condenser 300 from exchanging heat through air, ensuring that cold air can be blown out from the front of the body 100 and the heat of the condenser 300 is discharged from the rear.

[0038] like Figure 1 As shown, the height of the evaporator 200 is less than the height of the condenser 300. Specifically, the evaporator 200 extends downwards from the top of the unit 100 to the middle of the unit 100, while the condenser 300 extends from the top of the unit 100 to the lower part of the unit 100. During the cooling process, the evaporator 200 has a low temperature, and when it comes into contact with the air, the water vapor in the air condenses into water droplets. These water droplets flow downwards along the blades of the condenser 300. Therefore, a drip tray 400 is provided below the evaporator 200 to collect the condensate. The drip tray 400 collects the condensate, preventing it from flowing onto other electrical components inside the unit 100. The drip tray 400 has a drain outlet 410 facing the condenser 300. The horizontal height of the drain outlet 410 is higher than the bottom surface of the condenser 300, allowing the condensate flowing out of the drain outlet 410 to flow under gravity to at least a portion of the heat dissipation surface of the condenser 300. In other words, after the condensate is collected in the water collection pan 400, the condensate will flow out from the water outlet 410. The water outlet 410 faces the condenser 300 and is at a certain height from the bottom surface of the condenser 300. Under the action of gravity, the condensate will flow down the heat dissipation surface (heat dissipation fins or heat dissipation tubes) of the condenser 300 after flowing out of the water outlet 410, thereby achieving the purpose of cooling the surface of the condenser 300 with condensate.

[0039] Because the condensate cooling system is implemented within an integrated air conditioner, which has a compact layout, this solution adds a water outlet 410 facing the condenser 300, enabling gravity flow. This perfectly overcomes the inherent limitations of integrated units, such as limited space and difficulty in laying long and complex pipelines. Furthermore, since it relies entirely on gravity, it eliminates the need for external power sources like water pumps or solenoid valves. It automatically and continuously guides the condensate generated during air conditioner operation to the heat dissipation surface of the condenser 300, employing a zero-energy cooling method. This improves basic energy efficiency, and the system virtually eliminates additional points of failure. Its robust structure and lifespan are consistent with the entire unit, resulting in extremely low maintenance costs.

[0040] Furthermore, such as Figure 5 , Figure 8 As shown, the water collection tray 400 includes a connected water collection trough 420 and a water channel 430. The water collection trough 420 is located directly below the evaporator 200, and the projection of the evaporator 200 on the horizontal plane lies within the water collection trough 420, ensuring that the condensate generated in all parts of the evaporator 200 can be completely collected without any leakage. This full-coverage collection is the fundamental guarantee for all subsequent utilization effects, avoiding problems such as water splashing due to insufficient area of ​​the water collection tray 400, water dripping into the interior of the machine body 100, causing corrosion, electrical short circuits, or efficiency loss. The outlet 410 is located on the side of the water collection channel 430 near the condenser 300. It first quickly gathers the water that is scattered on a large area of ​​the water receiving tank 420 into a centralized water collection channel 430. This not only accelerates the movement of water towards the outlet 410 and avoids the stagnation and evaporation loss that may occur when the water flows in a wide and shallow water tank, but more importantly, it provides a stable flow channel for the water flow, ensuring the continuity and stability of the water flow at the outlet 410.

[0041] like Figures 2 to 4 As shown, two parallel and spaced-apart air ducts 500 are provided between the evaporator 200 and the condenser 300, separated by a partition plate 600. To avoid affecting the existing component layout, the water collection channel 430 passes under the partition plate between the two air ducts 500, ensuring that the water system and air ducts do not interfere with each other. This guarantees that both air ducts 500 leading to the evaporator 200 and condenser 300 can obtain maximum effective ventilation area, free from the constraints of the water system layout, thus ensuring the overall heat exchange efficiency of the unit. Since the water collection channel 430 is confined between the two air ducts 500, its path to the outlet 410 is the shortest and most direct. This reduces water flow resistance, accelerates drainage, avoids water accumulation, and also facilitates the rapid delivery of cold water to the condenser 300, improving the immediacy of cooling.

[0042] like Figure 9 , Figure 10As shown, in a standard water outlet 410 without a guide ramp, water drips vertically downwards primarily due to gravity. The landing point is uncertain, influenced by factors such as the air conditioner's installation level, water flow magnitude, and wind force. Therefore, in this embodiment, the water outlet 410 has a guide ramp sloping downwards towards the condenser 300, providing the water flow with a definite initial direction. This allows the water to acquire a horizontal velocity component pointing towards the condenser 300 the instant it leaves the outlet 410. This is like installing a "aiming device" on the water flow, ensuring it accurately hits the predetermined heat dissipation area of ​​the condenser 300, greatly improving accuracy and reliability. The water flow guided by the guide ramp not only has a clear direction but also gains greater initial kinetic energy. When this more powerful water flow impacts the heat dissipation fins of the condenser 300, it better overcomes the surface tension of the water, splashing out and more effectively wetting a larger heat dissipation surface area, rather than flowing down only a few paths like slowly dripping water. This impact spreading effect significantly improves the contact efficiency between the water and the heat exchange area, thereby enhancing the cooling effect.

[0043] Furthermore, the outlet 410 should not directly contact the condenser 300 to avoid deformation caused by the outlet 410 pressing against the condenser 300. Also, if the outlet 410 is in contact with the condenser 300, vibrations during handling or moving of the integrated air conditioner can easily cause the drip tray 400 to loosen. Therefore, the outlet 410 needs to maintain a certain distance from the condenser 300, which is 2-2.5mm. This specific distance ensures that the condensate flowing from the outlet 410 can, under the influence of gravity, fall stably and accurately onto the heat dissipation fins of the condenser 300 with minimal horizontal deviation and energy loss. Too large a distance will cause the water to scatter and fall inaccurately; too small a distance may cause the water to only slide along the edge of the condenser 300, failing to effectively wet the core heat dissipation area.

[0044] Based on the above embodiments, condensate will be further used to cool the condenser 300, as shown in the following scheme: like Figures 1 to 4As shown, a water-collecting tray 700 is provided at the bottom of the unit 100. The projection of the condenser 300 on the horizontal plane is at least partially located within the water-collecting tray 700. A rotating water-spinning plate 800 is provided within the water-collecting tray 700 to throw the condensate collected in the water-collecting tray 700 towards the condenser 300. That is, the condensate flows downwards along the condenser 300, but it is not necessarily completely evaporated during the flow. Excess condensate flows into the water-collecting tray 700 at the bottom of the unit 100. The condensate in the water-collecting tray 700 is then thrown back towards the condenser 300 by the water-spinning plate 800, thus providing secondary cooling to the condenser 300. The water-collecting tray 700, as a final collector located at the bottom of the system, ensures that all condensate that is not evaporated is recovered and then reused by the water-spinning plate 800. This achieves a closed-loop cycle in the utilization of water resources, maximizing the potential for water-saving cooling.

[0045] Furthermore, such as Figure 6 , Figure 7 As shown, the condenser 300 and the rear panel of the body 100 (not shown in the figure) form a gap along the width direction of the body 100. This gap ensures that the condenser 300 will not come into contact with the rear panel of the body 100 during transportation and movement, avoiding damage from compression. The water splashed out by the water-splashing tray 800 should cover the condenser 300 as much as possible. The water-splashing tray 800 and the condenser 300 are arranged side by side along the length direction of the body 100, and the water-splashing tray 800 should protrude slightly towards the rear panel of the body 100 from the condenser 300. That is, the water-splashing tray 800 should be set to correspond to the gap, so that part of the splashed condensate directly reaches the condenser 300, and the other part is splashed onto the condenser 300 through the rear panel. Some water droplets directly impact the fins of condenser 300 with maximum kinetic energy, achieving instant and efficient evaporation and heat absorption. Other water droplets impact the large-area back plate and are broken into finer water mist, which is then reflected and covers condenser 300. This dual mechanism ensures the maximization and uniform wetting of the heat dissipation area of ​​condenser 300.

[0046] Furthermore, the integrated air conditioner has a compact internal structure. Different models or batches of the unit 100 may have slight differences in the size of the gap between the condenser 300 and the back panel, as well as the shape of the water tray 700. In this embodiment, the water tray 800 is at least partially located within the gap, or the water tray 800 is located on the side of the gap. According to the specific internal space layout, the most reasonable installation scheme that does not interfere with other components can be selected, without sacrificing other performance or increasing manufacturing costs in order to forcibly meet an overly specific position requirement.

[0047] The rotation axis of the water-spinning pan 800 is positioned near one edge of the condenser 300, for example, from... Figure 1 Viewed directly from the condenser 300, the water-spinning tray 800 is located on the left side of the condenser 300. The water-spinning tray 800 rotates counterclockwise to throw the condensate upwards, so that most of the water droplets generated when the water-spinning tray 800 rotates are concentrated in a fan-shaped area facing the main body of the condenser 300.

[0048] like Figure 11 As shown, the water-spinning disc 800 includes a disc body 810 and multiple water-spinning blades 820. The disc body 810 is disc-shaped, and the water-spinning blades 820 are circumferentially arranged on a first and second axial side of the disc body 810. That is, a first set of blades is provided on the first side of the disc body 810, and a second set of blades is provided on the second side of the disc body 810. This transforms a single rotating disc into two independent liquid distributors, allowing one motor and one rotating component to simultaneously perform two tasks: directly spraying water into the condenser 300 for primary cooling, and spraying water onto the rear panel to generate a splash mist for auxiliary cooling. This integrated design avoids the complexity of using two independent systems, achieving composite functions with minimal cost and maximum reliability. Furthermore, the thickness of the water-spinning blades 820 gradually decreases from the center of the disc body 810 towards the outer periphery. When the blades rotate at high speed, their outer periphery has the highest linear velocity, resulting in the greatest air disturbance. Thinning the outer blades significantly reduces their frontal area and rotational resistance, thereby lowering the load and energy consumption of the drive motor and reducing wind noise. The thinner outer edge also helps to form smaller, more uniform water droplets when cutting and ejecting the water film, which is more conducive to evaporative heat exchange than the coarser water column produced by thicker edges. This design actively creates a better atomization effect.

[0049] When the integrated air conditioner starts working, the evaporator 200 has a low temperature, causing water vapor in the air to condense upon contact with it. This condensate flows down the surface of the evaporator 200 into the drip tray 400, is collected by the drip trough 420, and then flows from the outlet 410 of the drain channel 430 to the condenser 300. The condensate then flows down the surface of the condenser 300, simultaneously cooling it. Any condensate that is not completely evaporated and flows down the surface of the condenser 300 eventually falls into the collection pan 700 for collection. The condensate in the collection pan 700 is then splashed onto the condenser 300 by the rotating splash plate 800 for secondary cooling. This solution cleverly utilizes the inherent height differences and narrow gaps within the integrated air conditioner, with gravity flow and centrifugal splashing as the core of two-stage efficiency enhancement. It constructs a condensate internal circulation system with zero additional energy consumption, an extremely compact structure, and reliable operation, thereby converting waste condensate into a highly efficient coolant. This achieves comprehensive and uniform cooling of the condenser 300, ultimately significantly improving the overall energy efficiency of the unit.

[0050] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
