Description

Technical Field

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

[0002] Portable air conditioners (or workstation air conditioners) are widely used in localized cooling scenarios such as offices and data centers due to their flexibility and lack of professional installation requirements. When these air conditioners are running in cooling mode, condensation will form on the evaporator surface; therefore, a water collection box is usually installed inside the unit to collect this condensation.

[0003] The existing solutions for handling condensate from portable air conditioners mainly rely on water collection boxes. Users manually remove the boxes periodically and empty the water. While this method ensures the portability of the air conditioner, it has the following significant drawbacks: (1) Users need to frequently monitor the water level and empty the water promptly, otherwise the water may overflow, damaging the internal components of the air conditioner or causing immersion in the environment; (2) For applications requiring long-term fixed placement, frequent manual drainage undoubtedly brings great trouble and inconvenience to users, resulting in a poor user experience.

[0004] Therefore, existing technologies lack a condensate drainage solution that can balance the portability of portable air conditioners with the convenience of fixed use, and properly address the conflict between appearance and function. The purpose of this utility model is to solve one or more of the aforementioned deficiencies in the existing technology. Utility Model Content

[0005] This utility model aims to overcome the aforementioned shortcomings of the prior art and provide a portable air conditioner. Its core function is to solve the problem that existing portable air conditioners cannot simultaneously achieve convenience for mobile use and convenient drainage for stationary use, while ensuring that the drainage function does not compromise the overall appearance of the product.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A portable air conditioner includes a body, an evaporator disposed within the body, and a removable water collection box. The water collection box has a water inlet for collecting condensate flowing from the evaporator. The water collection box has a front panel forming part of the outer surface of the front of the body, and a side panel connected to the front panel. A water pipe for connecting an external drain pipe is provided on one side panel of the water collection box. A through hole for the drain pipe to pass through is provided on the corresponding side wall of the body. An openable and closable end cap is provided at the outlet end of the water pipe.

[0007] In the aforementioned portable air conditioner, the end cap is a removable rubber plug.

[0008] In the aforementioned portable air conditioner, the water inlet pipe extends outward from the inner surface of the side wall of the water inlet box, and the height of the inlet pipe is lower than the maximum water level set inside the water inlet box.

[0009] In the aforementioned portable air conditioner, the outer circumference of the outlet end of the water inlet pipe is provided with an external thread for connecting to the drain pipe; or, the outer circumference of the water inlet pipe is provided with multiple radially protruding anti-detachment rings for engaging with the drain pipe.

[0010] In the aforementioned portable air conditioner, a water collection tank is fixed below the evaporator, and the water collection tank is equipped with a drain pipe; the outlet of the drain pipe of the water collection tank is suspended above the inlet of the water receiving box, so that the condensate flowing out of the drain pipe falls directly into the inlet.

[0011] In the aforementioned portable air conditioner, the water collection tank is provided with an installation part, which is fixedly connected to the evaporator.

[0012] In the aforementioned portable air conditioner, the unit body is provided with a support frame located below the evaporator, and the water collection tank is fixed on the support frame.

[0013] In the aforementioned portable air conditioner, the support frame has an upwardly extending fixed side with a fixing hole; the side wall of the water collection tank has a fixing part that mates with the fixing hole, and the water collection tank and the support frame are fixedly connected by inserting the fixing part into the fixing hole.

[0014] In the aforementioned portable air conditioner, the top surface of the water receiving box is recessed inward to form a collection groove, and the water inlet is located at the lowest point of the collection groove.

[0015] In the aforementioned portable air conditioner, an elastic sleeve is embedded in the through hole, and the inner diameter of the elastic sleeve is smaller than the outer diameter of the drain pipe.

[0016] Compared with the prior art, the advantages of this utility model are: The front panel of the water receiving box is designed to form part of the outer surface of the front of the unit, while the water receiving pipe for connecting the external drain pipe is set on its side panel. This ensures that the aesthetics and integrity of the front of the air conditioner are not compromised, and solves the common visual conflict problem when setting functional interfaces on components that are the main appearance surface.

[0017] A closable end cap is installed at the water inlet, giving the core structure two operating modes: In mobile scenarios, with the end cap closed, the water inlet box functions as an independent water storage container, allowing users to easily empty it when full, perfectly suited to the characteristics of portable air conditioners that require frequent movement and are inconvenient for external pipe connections. In stationary scenarios, opening the end cap allows for automatic and continuous drainage via an external drain pipe, eliminating the hassle of manual emptying and greatly improving the convenience of long-term use in a fixed location. This fundamentally solves the core contradiction of existing portable air conditioners that cannot balance mobility and the convenience of stationary use.

[0018] Through the above structure, a dual-mode drainage function that can be flexibly switched without damaging the appearance is realized in the portable air conditioner, thereby simultaneously meeting users' multiple needs for product aesthetics, portability and automation for fixed use, and providing an unprecedented user experience.

[0019] Furthermore, the end cap is a removable rubber plug. Utilizing the natural elasticity and deformability of rubber, the rubber plug can be tightly pressed into the outlet end of the water inlet pipe, achieving an interference fit. This sealing method effectively prevents water leakage from the interface within the water inlet box during water storage mode, while also preventing external dust and insects from entering. Compared to end caps that may be screwed on, the rubber plug is extremely easy to install and remove, requiring no tools or rotation; simply pull and insert, greatly enhancing the user experience during mode switching.

[0020] Furthermore, the water inlet pipe extends outward from the inner surface of the side wall of the water inlet box, and the height of the pipe opening is lower than the maximum water level set inside the water inlet box. By setting the height of the water inlet pipe below the safe water level, a safe buffer space is created between the two. Even if the drainage rate is temporarily equal to or slightly less than the inflow rate, the water level will remain stable at the pipe opening height, and there is absolutely no chance of reaching the dangerous water level that could overflow the water inlet box. This fundamentally eliminates the possibility of water overflowing, and the system reliability is significantly improved.

[0021] Furthermore, the outlet end of the water inlet pipe is provided with an external thread for connecting to the drain pipe; or, the outer circumference of the water inlet pipe is provided with multiple radially protruding anti-detachment rings for engaging with the drain pipe. The external thread design can directly mate with standard drain pipes and matching clamps on the market. By tightening the clamps, a secure mechanical lock and excellent sealing effect can be achieved, capable of withstanding a certain amount of hose tension and water pressure, preventing leakage or detachment at the interface. This is suitable for long-term fixed installation scenarios with extremely high requirements for connection strength and sealing. The anti-detachment ring design is a quick-plug connection method with anti-detachment as its core feature. Installation is extremely convenient, requiring no tools; simply push the hose in. Axial locking is achieved through the interference between the anti-detachment ring and the inner wall of the hose. This structure is specially designed with shock-absorbing properties. When the portable air conditioner vibrates during operation, the elastic snap-fit ​​effect effectively prevents the hose from loosening due to vibration, providing a smooth and reliable user experience.

[0022] Furthermore, a water collection tank is fixed below the evaporator, and a drain pipe is installed in the water collection tank. The outlet of the drain pipe of the water collection tank is suspended above the inlet of the water receiving box, so that the condensate flowing from the drain pipe falls directly into the inlet. The task of catching dripping condensate is assigned to the fixed water collection tank, while the removable water receiving box acts as a static water bucket. This functional separation means that the inlet of the water receiving box does not need to be designed to be large enough to align with all possible dripping points; its size can be significantly reduced, only needing to meet the drain pipe of the water collection tank. A smaller inlet greatly reduces the risk of condensate stored in the water receiving box splashing out from the interface due to violent shaking when moving or transporting the air conditioner, improving the safety and cleanliness of the product during movement.

[0023] Furthermore, the water collection tank is equipped with a mounting part, through which it is fixedly connected to the evaporator. The water collection tank is directly fixed to the evaporator via the mounting part. As a large and robust core component inside the air conditioner, the evaporator provides an extremely stable and reliable mounting base for the water collection tank. This connection method avoids installing the water collection tank on potentially deformable plastic panels or secondary supports, ensuring that the water collection tank will not experience additional shaking or displacement when the air conditioner is running, moved, or subjected to vibration. This guarantees the stability of its drain pipe interface and reduces the risk of loosening or leakage due to vibration.

[0024] Furthermore, the machine body is equipped with a support frame located below the evaporator, and the water collection tank is fixed to the support frame. Dedicated support frames are typically designed and manufactured with higher structural strength and rigidity. Compared to fixing the water collection tank to potentially weaker plastic casings or non-load-bearing parts of the evaporator, the support frame provides a stable and reliable mounting base for the water collection tank and its connected drain pipe. This effectively prevents fatigue damage or positional displacement of the water collection tank's fixing points due to vibration during long-term use or movement, thereby ensuring the long-term stability and reliability of the drainage system.

[0025] Furthermore, the support frame has an upwardly extending fixed side with a fixing hole; the side wall of the water collection tank has a fixing part that mates with the fixing hole, and the water collection tank and the support frame are fixedly connected by inserting the fixing part into the fixing hole. The cooperation between the fixing hole and the fixing part precisely positions the water collection tank in the horizontal direction, preventing it from shifting laterally on the support frame during use. This ensures that the outlet of the drain pipe of the water collection tank is always precisely suspended above the inlet of the water receiving box, guaranteeing the accuracy and reliability of water flow transmission between the two-stage drainage system, and structurally eliminating the risk of leakage caused by improper assembly.

[0026] Furthermore, the top surface of the water collection box is recessed inward to form a collection groove, and the water inlet is located at the lowest point of this collection groove. The collection groove can expand the collection range of condensate, and the recessed structure, through its inclined or curved surface, can actively guide the dripping condensate, allowing it to flow naturally to the location of the lowest water inlet under the action of gravity. This completely avoids the ineffective retention, accumulation, or formation of puddles that are difficult to evaporate on the top surface of the water collection box, ensuring that the condensate is efficiently guided into the interior of the water collection box.

[0027] Furthermore, an elastic sleeve is embedded within the through hole, the inner diameter of which is smaller than the outer diameter of the drain pipe. When the drain hose passes through this sleeve, the elastomer material deforms, applying a continuous, uniform, and powerful radial clamping force to the outer wall of the hose. This clamping force is converted into a huge static friction force, which can effectively resist the axial displacement caused by the hose sagging due to its own weight, accidental pulling, or water flow impact, fundamentally eliminating the possibility of the hose detaching from the interface.

Detailed Implementation

[0030] A portable air conditioner includes a body 100, an evaporator 200 disposed within the body 100, and a removable water collection box 300. The water collection box 300 has a water inlet 310 for collecting condensate flowing from the evaporator 200. The water collection box 300 has a front panel 320 forming part of the outer surface of the front of the body 100, and a side panel 330 connected to the front panel 320. A water collection pipe 340 for connecting an external drain pipe 500 is provided on one side panel 330 of the water collection box 300. A through hole 110 for the drain pipe 500 to pass through is provided on the corresponding side wall of the body 100. An openable and closable end cap 360 is provided at the outlet end of the water collection pipe 340.

[0031] The front panel 320 of the water receiving box 300 is designed to form part of the outer surface of the front of the body 100. At the same time, the water receiving pipe 340 for connecting the external drain pipe 500 is set on its side panel 330, which ensures that the aesthetics and integrity of the front of the air conditioner are not compromised and solves the common visual conflict problem when setting functional interfaces on components that are the main appearance surface.

[0032] A closable end cap 360 is installed at the outlet of the water inlet pipe 340, giving the core structure two operating modes: In mobile scenarios, with the end cap 360 closed, the water inlet box 300 functions as an independent water storage container, allowing users to easily empty it when full, perfectly adapting to the characteristics of portable air conditioners that require frequent movement and are inconvenient to connect external pipes. In fixed scenarios, opening the end cap 360 allows for automatic and continuous drainage via the drain pipe 500 connected to the water inlet pipe 340, eliminating the hassle of manual emptying and greatly improving the convenience of long-term use in a fixed location. This fundamentally solves the core contradiction of existing portable air conditioners that cannot balance mobility and the convenience of fixed use.

[0033] Through the above structure, a dual-mode drainage function that can be flexibly switched without damaging the appearance is realized in the portable air conditioner, thereby simultaneously meeting users' multiple needs for product aesthetics, portability and automation for fixed use, and providing an unprecedented user experience.

[0034] 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.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0036] 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.

[0037] 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.

[0038] See Figures 1 to 7 This invention relates to an embodiment of a portable air conditioner. The portable air conditioner includes a body 100, which generally includes a frame and an outer shell covering the frame. Major components such as the evaporator 200, radiator, and compressor are all located inside the body 100. A removable water collection box 300 is also provided inside the body 100, that is, the water collection box 300 is pulled out and located at the lower part of the body 100. The water collection box 300 has a water inlet 310 for collecting condensate flowing down from the evaporator 200.

[0039] The water collection box 300 has a front panel 320 and a side panel 330 connected to the front panel 320. The front panel 320 is part of the front outer surface of the unit 100, that is, the water collection box 300 is similar to a drawer. A water collection pipe 340 for connecting an external drain pipe 500 is provided on one side panel 330 of the water collection box 300. By designing the front panel 320 of the water collection box 300 to form part of the front outer surface of the unit 100, and cleverly placing the water collection pipe 340 for connecting the external drain pipe 500 on its side panel 330, this design ensures that the aesthetics and integrity of the front of the air conditioner are not compromised, and solves the common visual conflict problem when setting functional interfaces on components that are the main appearance surfaces.

[0040] Correspondingly, a through hole 110 for the water supply and drainage pipe 500 is provided on the corresponding outer side wall of the body 100, and an openable and closable end cap 360 is provided at the outlet end of the water inlet pipe 340.

[0041] In mobile scenarios, with the end cap 360 closed, the water collection box 300 functions as an independent water storage container, allowing users to easily empty it when full. This perfectly suits the characteristics of portable air conditioners, which require frequent movement and are inconvenient for external pipe connections. In fixed scenarios, opening the end cap 360 allows for automatic and continuous drainage via the water collection pipe 340 and the external drain pipe 500, eliminating the hassle of manual emptying and greatly improving the convenience of long-term use in a fixed location. This fundamentally solves the core contradiction of existing portable air conditioners that cannot balance mobility and the convenience of fixed use.

[0042] Furthermore, the end cap 360 is a removable rubber plug. This plug can be attached to the water tank or the side wall of the main body 100 via a tether or other means, preventing it from being easily lost when using the drain pipe 500. Utilizing the natural elasticity and deformability of rubber, the plug can be tightly pressed into the outlet end of the water inlet pipe 340, achieving an interference fit. This sealing method effectively prevents water leakage from the water inlet box 300 during mobile applications, while also preventing external dust and insects from entering. Compared to the end cap 360, which may use a threaded tightening mechanism, the rubber plug is extremely easy to install and remove, requiring no tools or rotation; simply pull and insert, greatly enhancing the user experience during mode switching.

[0043] The water inlet pipe 340 extends outward from the inner surface of the side wall of the water receiving box 300. Generally, the water inlet pipe 340 is positioned towards the rear of the water receiving box 300 to maintain structural stability at the front. The height of the pipe opening is lower than the maximum water level set inside the water receiving box 300. As soon as the water level in the water receiving box 300 exceeds the pipe opening, the drainage process begins immediately. This prevents ineffective accumulation of water below the pipe opening, significantly reducing the actual water storage capacity and load of the water receiving box 300, allowing for faster water turnover. It fundamentally eliminates the risk of overflow. By setting the pipe opening of the water inlet 340 below the safe water level, a safe buffer space is created between the two. Even if the drainage speed is temporarily equal to or slightly less than the inlet speed, the water level will remain stable at the pipe opening height, with absolutely no chance of reaching the dangerous water level that could overflow the water receiving box 300. This fundamentally eliminates the possibility of overflow, significantly improving system reliability.

[0044] The connection structure between the water inlet pipe 340 and the drain pipe 500 includes, but is not limited to, the following structural forms: One type features an external thread on the outer circumference of the outlet end of the 340 water inlet pipe for connecting to the 500 drain pipe. This is a standardized and versatile connection method. It can be directly used with standard drain hoses and matching hose clamps (hose clamps) available on the market. By tightening the hose clamp, a secure mechanical lock and excellent sealing effect can be achieved. It can withstand a certain amount of hose tension and water flow pressure, preventing leakage or detachment at the joint. It is suitable for long-term fixed installation scenarios where extremely high connection strength and sealing requirements are required.

[0045] Another type features multiple radially protruding anti-detachment rings 341 on the outer circumference of the water inlet pipe 340, used for engaging with the drain pipe 500. This is a quick-plug connection method with anti-detachment as its core feature. Installation is extremely convenient, requiring no tools; simply push the hose in, and axial locking is achieved through the interference between the anti-detachment rings 341 and the inner wall of the hose. This structure is specially designed with shock-absorbing and buffering characteristics. When the portable air conditioner vibrates during operation, the elastic snap-fit ​​effect effectively prevents the hose from loosening due to vibration, providing a smooth and reliable user experience.

[0046] Based on the above embodiments, in this embodiment, a water collection tank 400 is fixed below the evaporator 200. The water collection tank 400 is equipped with a drain pipe, and the outlet of the drain pipe is suspended above the inlet 310 of the water receiving box 300, so that the condensate flowing out of the drain pipe falls directly into the inlet 310. The water collection tank 400 serves as a primary drainage device, undertaking the main function of collecting and initially draining most of the condensate. That is, the horizontal projection of the evaporator 200 is all located within the water collection tank 400, so that the condensate falling from the evaporator 200 can all fall into the water collection tank 400. The water receiving box 300 serves as a secondary drainage device. The inlet 310 of the water receiving box 300 does not need to be designed to be very large to align with all possible dripping points; its size can be significantly reduced, only needing to meet the connection with the drain pipe of the water collection tank 400. A smaller water inlet 310 greatly reduces the risk of condensate stored in the water collection box 300 splashing out from the interface due to violent shaking when the air conditioner is moved, thus improving the safety and cleanliness of the product during movement.

[0047] like Figure 3 , Figure 4 As shown, the fixing of the water collection tank 400 can be achieved in ways including but not limited to the following, and any one of the following methods can be used, or multiple methods can be used simultaneously: One design involves a water collection tank 400 with a mounting part 410, which is fixedly connected to the evaporator 200. Generally, the evaporator 200 has mounting brackets at both ends of its evaporation tubes to maintain the spacing between them. The mounting part 410 of the water collection tank 400 can protrude upwards and be connected to the mounting brackets with bolts, effectively suspending the water collection tank 400 below the evaporator 200. This simplifies the number of parts and structural complexity inside the unit 100. The installation position of the water collection tank 400 is determined by the evaporator 200 itself. This direct connection ensures that the water collection tank 400 is always precisely positioned directly below the drip line or the area where condensate drips most concentratedly from the evaporator 200, achieving maximum water collection efficiency. This not only reduces mold costs and assembly time but also makes the internal space more compact and organized, leaving more space for the layout of other components (such as fans and air ducts), which is beneficial for optimizing the overall design.

[0048] Another design features a support frame 600 with an upwardly extending fixing edge 610 and fixing holes 620. The side wall of the water collection tank 400 has a fixing part 420 that mates with the fixing holes 620. The water collection tank 400 and the support frame 600 are fixedly connected by the fixing part 420 inserted into the fixing holes 620. The water collection tank 400 becomes a functional module that can be independently installed and positioned. This design provides significant design flexibility, especially suitable for models where the evaporator 200's structure is not conducive to direct installation of the water collection tank 400, or where independent support is required to achieve a better flow path. It allows engineers to flexibly optimize the layout of the water collection tank 400 without altering the design of the evaporator 200. Compared to fixing the water collection tank 400 to potentially weak plastic shells or non-load-bearing parts of the evaporator 200, the support frame 600 provides a stable and reliable mounting base for the water collection tank 400 and its connected drain pipe 500. This effectively prevents fatigue damage or positional displacement of the 400 fixed point of the water collection tank due to vibration during long-term use or relocation, thereby ensuring the long-term stability and reliability of the drainage system.

[0049] To better collect condensate, the top surface of the water collection box 300 is recessed inward to form a collection groove 350, and the water inlet 310 is located at the lowest point of the collection groove 350. Figure 5 As shown, a long, narrow collection trough 350 is formed on the top surface of the water receiving box 300. One end of the collection trough 350 is higher than the other end, and the water inlet 310 is located at the bottom end of the collection trough 350. This structure ensures that the water collected in the collection trough 350 will preferentially and completely enter the water receiving box 300 through the water inlet 310, and will not cause water to bypass the water inlet 310 due to water surface tension or slight flow direction deviation, thus preventing water from accumulating at the top edge of the water receiving box 300 or even accidentally overflowing. This greatly improves the system's error prevention capability and operational certainty.

[0050] In addition, an elastic sleeve 120 is embedded in the through hole 110 on the side wall of the body 100. The inner diameter of the elastic sleeve 120 is smaller than the outer diameter of the drain pipe 500. By establishing an interference fit mechanical relationship, when the drain hose passes through this sleeve, the elastomer material deforms and applies a continuous, uniform, and strong radial clamping force to the outer wall of the hose. This clamping force is converted into a huge static friction force, which can effectively resist the axial displacement of the hose caused by its own weight sagging, accidental pulling, or water flow impact, fundamentally eliminating the possibility of the hose falling off from the interface. Its reliability is far superior to that of a simple connection with a smooth pipe wall. A removable cover 130 is also provided on the side wall of the body 100. When the drain pipe 500 is not in use, the cover 130 can be used to seal the through hole 110 to prevent foreign objects from entering the body 100.

[0051] The present invention achieves flexible and reliable switching between the two modes of "mobile water storage" and "fixed automatic drainage" for portable air conditioners by setting a water pipe 340 with a switch on the side of the pull-out water box 300 integrated with the appearance, and constructing a two-stage drainage system in which the water collection tank 400 and the water box 300 work together. At the same time, it perfectly balances the aesthetics of the whole machine, the reliability of drainage and the convenience of use.

[0052] 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.
