Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange equipment, and in particular to an outdoor portable air conditioner. Background Technology

[0002] Portable air conditioners are increasingly used in homes, small offices, and other settings due to their advantages of not requiring fixed installation and being easily movable.

[0003] Existing portable air conditioners generally adopt a layout where the condenser and evaporator are located on the same level, meaning they are arranged side-by-side or overlapping horizontally inside the device. For example, Chinese patent document CN112361463A discloses a portable air conditioner that includes a heat exchange structure and a stabilizing structure. It includes an evaporation chamber and a condensation chamber arranged side-by-side, separated by an air guide plate. One end of the air guide plate extends to the air outlet of the evaporation chamber, and the other end extends to the air outlet of the condensation chamber. The stabilizing structure is located below the heat exchange structure to support it.

[0004] However, this same-level layout has significant technical drawbacks: Firstly, the condenser and evaporator must occupy their respective installation positions in the same horizontal space, making it difficult to reduce the overall thickness of the equipment. This fails to meet users' demands for miniaturized and lightweight portable air conditioners, especially in space-constrained applications where placement flexibility is severely limited. Secondly, because the condenser and evaporator are on the same level, their airflow design is prone to interference, obstructing airflow within the equipment and reducing the actual airflow. Insufficient airflow directly affects the condenser's heat dissipation efficiency and the evaporator's heat exchange efficiency, ultimately leading to a decrease in the portable air conditioner's cooling effect. This makes it difficult to achieve the expected temperature control target, impacting the user experience. In particular, when this horizontally laid-out air conditioner is used in outdoor environments (such as cafes and tea shops with tables and chairs), the high temperature and humidity of the outdoor environment further reduce its cooling effect, making it unsuitable for complex environments.

[0005] In summary, existing portable air conditioners, due to the same-level layout of the condenser and evaporator, face technical problems such as large equipment thickness, difficulty in miniaturization, poor airflow, and poor cooling effect. In order to solve the above defects, the outdoor portable air conditioner of this application is proposed. Utility Model Content

[0021] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0022] like Figures 1 to 3 As shown, an outdoor portable air conditioner 10 includes a cabinet 100 and a heat exchange assembly. The upper part of the cabinet 100 has a cold air cavity 110 and a first inlet 120 and a cold air outlet 130 respectively connected to the cold air cavity 110. The lower part of the cabinet 100 has a heat dissipation cavity 140 and a second inlet 150 and a hot air outlet 160 respectively connected to the heat dissipation cavity 140. The heat exchange assembly includes an evaporator 210, a fan 220, a condenser 230, and a cooling fan 240. The air compressor 250, the evaporator 210 are located in the cold air cavity 110 and close to the cold air outlet 130, the fan 220 is located on the side of the evaporator 210 away from the cold air outlet 130, the radiator fan 240 is located on the hot air outlet 160, the condenser 230 is located on the end of the radiator fan 240 located in the heat dissipation cavity 140, and the air compressor 250 is located in the heat dissipation cavity 140. The air compressor 250, the condenser 230 and the evaporator 210 are connected in sequence.

[0023] It should be noted that the cabinet 100 is internally divided into an upper and lower independent cold air chamber 110 and a lower heat dissipation chamber 140. The cold air chamber 110 draws in external air through the first inlet 120, processes it, and then discharges cold air from the cold air outlet 130. The heat dissipation chamber 140 introduces external air through the second inlet 150 and finally discharges hot air from the hot air outlet 160, forming a physically isolated dual airflow channel. This results in a layered layout structure for the cold air chamber 110 and the heat dissipation chamber 140. The cold air circulation is as follows: the evaporator 210 is located inside the cold air chamber 110 near the cold air outlet 130, and a fan 220 is installed on the side furthest from the outlet. The fan 220 drives air to enter the cold air chamber through the first inlet 120, where heat exchange occurs as it flows through the evaporator 210 (the air is cooled), and finally, cold air is discharged through the cold air outlet 130. Furthermore, the heat dissipation cycle is as follows: the condenser 230 is located within the heat dissipation cavity 140 and directly connected to the cooling fan 240 at the hot air outlet 160. The air compressor 250 is also located within the heat dissipation cavity. After the air compressor 250 compresses the refrigerant, the high-pressure refrigerant first enters the condenser 230 to dissipate heat and liquefy, and then flows into the evaporator 210 to absorb heat and vaporize, forming a complete refrigeration cycle. The cooling fan 240 accelerates the airflow within the heat dissipation cavity, and the external air drawn in through the second inlet 150 carries away the heat from the condenser 230 and is discharged from the hot air outlet 160. In this way, by placing the evaporator 210 (the core component of the cold air system) and the condenser 230 (the core component of the heat dissipation system) in the upper and lower layers of the cold air cavity 110 and the heat dissipation cavity 140 respectively, replacing the same-layer layout in the prior art, the horizontal space occupation is significantly reduced, the overall thickness of the equipment is effectively reduced, and it is more suitable for mobile use in narrow outdoor spaces. Furthermore, the cold air chamber 110 and the heat dissipation chamber 140 are independently separated to avoid mutual interference between the two airflows and reduce wind resistance. The fan 220 and evaporator 210, and the cooling fan 240 and condenser 230 are directly connected, effectively shortening the airflow path, increasing air circulation speed, and increasing the actual air volume. Increased air volume enhances the heat absorption efficiency of the evaporator 210 and the heat dissipation efficiency of the condenser 230, directly improving the cooling effect and ensuring rapid cooling capability in high-temperature outdoor environments. Furthermore, the layered layout allows for the compact installation of various components (air compressor 250, fan 220, cooling fan 240, etc.) within the heat dissipation chamber 140, simplifying the internal structure, improving space utilization, enhancing equipment mobility, and better adapting to the needs of outdoor coffee shops, milk tea shops, and other similar settings. Thus, the outdoor portable air conditioner 10 of this application effectively reduces equipment thickness, achieves miniaturization, optimizes the airflow path, improves air volume and efficiency, and has a compact structure, making it suitable for high-temperature and high-humidity outdoor environments.

[0024] like Figures 1 to 3As shown, in one embodiment, the cold air outlet 130 is located on the front of the cabinet 100, the hot air outlet 160 is located on the back of the cabinet 100, and the first inlet 120 and the second inlet 150 are both located on the same side of the cabinet 100.

[0025] It should be noted that the cold air outlet 130 is located on the front of the cabinet 100 and connects to the cold air cavity 110, used to directly deliver cold air to the user activity area; the hot air outlet 160, corresponding to the heat dissipation cavity 140, is located on the back of the cabinet 100, which can guide the hot air generated during the heat dissipation process to non-user areas, preventing hot air from flowing back to the cold air action area. This structure of front-out cold air and rear-out hot air can effectively separate the interference between cold air and hot air. Furthermore, the first inlet 120 (the air inlet of the cold air cavity 110) and the second inlet 150 (the air inlet of the heat dissipation cavity 140) are concentrated on the same side of the cabinet 100. This side is away from the user activity area and also away from the direction of hot air exhaust, so that external air (the ambient temperature air required by the cold air cavity 110 and the ambient temperature air required by the heat dissipation cavity 140) can be stably drawn in from the same side without being interfered with by the front cold air or the back hot air, forming an orderly airflow circulation of "same-side air intake and front and back side exhaust". In this way, when used in open outdoor environments, the airflow path can be effectively optimized, preventing hot or cold air from mistakenly flowing back into the first inlet 120 and the second inlet 150. This effectively improves the heat absorption efficiency of the evaporator 210 and the heat dissipation efficiency of the condenser 230, ensuring the cooling effect. Furthermore, this design effectively avoids airflow interference, improving cooling efficiency, and with only the cold air outlet 130 facing the user, it enhances the user experience.

[0026] like Figure 2 and Figure 3 As shown, in one embodiment, a partition 300 is provided inside the cabinet 100, such that the upper surface of the partition 300 and the inner sidewall of the cabinet 100 form a cold air cavity 110, and the lower surface of the partition 300 and the inner sidewall of the cabinet 100 form a heat dissipation cavity 140.

[0027] It should be noted that in this embodiment, by adding a horizontally arranged partition 300 inside the cabinet 100, the physical separation and precise construction of the cold air cavity 110 and the heat dissipation cavity 140 are achieved. Specifically, the partition 300 is horizontally arranged inside the cabinet 100, and its edge is tightly connected to the inner wall of the cabinet 100 (e.g., by welding, bolting, or sealing with sealant). With the partition 300 as the boundary, the interior of the cabinet 100 is divided into two independent cavities: the upper surface of the partition 300 and the inner wall of the cabinet 100 enclose the upper cold air cavity 110, which is used to accommodate refrigeration components such as the evaporator 210 and the fan 220; the lower surface of the partition 300 and the inner wall of the cabinet 100 enclose the lower heat dissipation cavity 140, which is used to accommodate core components for heat dissipation and refrigeration cycle such as the condenser 230, the cooling fan 240, and the air compressor 250. The partition 300 is designed to correspond to the airflow inlet and outlet positions of the cabinet 100. The cold air chamber 110 connects to the cold air outlet 130 on the front of the cabinet 100 and the first inlet 120 at the same height, ensuring that the fan 220 drives air into the cold air chamber from the first inlet 120, flows through the evaporator 210, and exits from the cold air outlet 130. The heat dissipation chamber 140 connects to the hot air outlet 160 on the back of the cabinet 100 and the second inlet 150 at the same height, ensuring that the cooling fan 240 drives air into the cabinet from the second inlet 150, removes heat from the condenser 230, and exits from the hot air outlet 160. Simultaneously, the partition 300 provides a stable mounting base for the components of the upper and lower cold air chambers 110 and heat dissipation chambers 140 (for example, the evaporator 210 can be fixedly mounted on the upper surface of the partition 300, and the air compressor 250 can be fixedly mounted on the inner bottom wall of the cabinet 100), ensuring that all components are securely installed within the cabinet 100. Thus, the tight connection between the partition 300 and the inner wall of the cabinet 100 effectively blocks airflow between the cold air cavity 110 and the heat dissipation cavity 140, preventing the mixing of low-temperature air in the cold air cavity 110 and high-temperature air in the heat dissipation cavity 140, eliminating airflow interference, ensuring the heat absorption efficiency of the evaporator 210 and the heat dissipation efficiency of the condenser 230, and further improving the cooling effect. It should be noted that the cabinet 100 can be divided into layers using a single partition 300, eliminating the need for complex hierarchical structures (such as using multiple side panels joined from top to bottom to form the cold air cavity 110 and the heat dissipation cavity 140), thereby reducing the number of parts, simplifying the processing and assembly of the cabinet 100, and lowering production costs. Furthermore, while dividing the cabinet 100 into the cold air cavity 110 and the heat dissipation cavity 140, the partition 300 also strengthens the overall structural strength of the cabinet 100. In addition, by dividing the cabinet 100 vertically with partitions 300, the vertical space of the cabinet 100 can be effectively utilized, thus effectively reducing the overall volume of the cabinet 100 and making it more suitable for outdoor use.

[0028] like Figure 2 and Figure 3As shown, in one embodiment, a water collection box 400 is provided on the partition 300, and the water collection box 400 is located below the evaporator 210.

[0029] It should be noted that during the refrigeration process, the evaporator 210 will produce condensate due to the cooling of the air. The water collection box 400 is located directly below the evaporator 210 and can directly collect the dripping condensate, preventing it from flowing randomly onto core components such as the fan 220 in the cold air cavity 110 or the air compressor 250 and condenser 230 in the heat dissipation cavity 140. This avoids short circuits caused by contact between condensate and electrical components, or corrosion caused by contact with metal components, effectively extending the service life of the equipment and ensuring the stable operation of the refrigeration system. Thus, the condensate produced by the evaporator 210 is collected.

[0030] like Figures 2 to 5 As shown, in one embodiment, a slot 170 is provided on the side of the cabinet 100 away from the second entrance 150. The slot 170 is connected to the heat dissipation cavity 140. The outdoor portable air conditioner 10 also includes a water tank 500, which is used to pass through the slot 170 to enter the heat dissipation cavity 140. The water tank 500 is used to communicate with the water collection box 400.

[0031] It should be noted that the water tank 500 is connected to the water collection box 400, which can collect the condensate water collected in the water collection box 400, significantly increasing the total condensate water storage capacity. Compared to relying solely on the small capacity of the water collection box 400, this avoids the need for users to frequently remove the water collection box 400 to empty the accumulated water. Especially in outdoor use scenarios, this significantly reduces the number of maintenance operations, ensures continuous and stable operation of the equipment, and improves ease of use. Furthermore, the water tank 500 passes through the tank groove 170 into the heat dissipation chamber 140, and the condenser 230 and air compressor 250 inside the heat dissipation chamber 140 are both high-heat-generating components. The low-temperature condensate stored in the water tank 500 can absorb some of the heat in the heat dissipation cavity 140, reducing the ambient temperature inside the heat dissipation cavity 140, indirectly reducing the heat dissipation load of the cooling fan 240, and improving the heat dissipation efficiency of the condenser 230. At the same time, the low-temperature water tank 500 and the air in the heat dissipation cavity 140 form a temperature difference convection, which helps to remove heat from the cavity, further ensuring the stable operation of the refrigeration system in outdoor high-temperature environments and avoiding the reduction of cooling effect due to insufficient heat dissipation. In addition, the cabinet slot 170 is opened on the side of the cabinet 100 away from the second inlet 150, which avoids the air intake channel of the heat dissipation cavity 140 (to prevent interference with the second inlet 150 to draw in cooling air), and makes full use of the unused space on the side of the cabinet 100 to install the water tank 500. It does not require additional functional areas on the front (cold air outlet 130 side) or back (hot air outlet 160 side) of the cabinet 100, nor does it require a separate large-capacity water storage space in the heat dissipation cavity 140, making the internal layout of the cabinet 100 more compact and taking into account both the water storage function and the miniaturization design requirements of the equipment. Finally, the water tank 500 can be pulled out and removed along the tank groove 170. This allows users to easily remove the water tank 500 periodically to empty the accumulated water, offering greater operational flexibility than fixed water storage structures. Furthermore, when there is a need for water replenishment outdoors (such as temporary humidification or cleaning of the equipment), the water tank 500 can be removed to hold clean water, achieving a dual function of "condensate storage + external water source utilization," thus improving the equipment's adaptability to complex outdoor environments. In addition, a drain hole is simply made on the inner bottom wall of the water collection box 400, and a flexible hose is connected to the drain hole, with the other end of the hose hanging down to the opening of the water tank 500. This simplifies the structure and avoids the risk of leakage caused by aging or loosening of the pipes.

[0032] like Figures 2 to 4 As shown, in one embodiment, a U-shaped baffle 600 is provided on the inner bottom wall of the heat dissipation cavity 140, and the opening of the U-shaped baffle 600 faces the tank groove 170, and the water tank 500 is adapted to be accommodated in the U-shaped baffle 600.

[0033] It should be noted that the opening of the U-shaped baffle 600 faces the tank groove 170, consistent with the pull-out direction of the water tank 500. Users do not need to overcome the obstruction of the U-shaped baffle 600 when disassembling or assembling the water tank 500; they can easily pull out or push in the water tank 500 simply by following the opening direction of the U-shaped baffle 600, making the operation process simpler. Especially in outdoor scenarios without tool assistance, this reduces maintenance difficulty and improves the user experience. At the same time, the simple structure of the U-shaped baffle eliminates the need for complex locking mechanisms, reducing manufacturing costs and the risk of failure. Furthermore, the three side walls of the U-shaped baffle 600 limit and fix the water tank 500, effectively preventing collisions between the water tank 500 and the inner wall of the heat dissipation cavity 140, the condenser 230, or the air compressor 250, compared to a water tank 500 without a fixed structure. This prevents damage to the water tank 500 or core components, improving the structural stability of the equipment in outdoor mobile scenarios.

[0034] like Figures 1 to 3 As shown, in one embodiment, the heat exchange assembly further includes an air collecting shell 260 and at least one air outlet ball 270. The air collecting shell 260 is disposed on the side of the evaporator 210 near the cold air outlet 130. The air collecting shell 260 has two mounting holes 261, which are respectively aligned with the two cold air outlets 130. The two air outlet balls 270 are respectively disposed in the two mounting holes 261 and extend out of the two cold air outlets 130.

[0035] It should be noted that the air collector shell 260 is fastened to the side of the evaporator 210 near the cold air outlet 130, and the edge of the air collector shell 260 is in close contact with the edge of the evaporator 210. Two mounting holes 261 are provided on the side of the air collector shell 260 away from the evaporator 210, and the air outlet ball 270 is tightly fixed in the mounting holes 261, allowing the air outlet ball 270 to pass through the cold air outlet 130. Thus, compared to the grille-like structure of the air outlet in existing air conditioners, the air outlet ball 270 in this application can concentrate the direction of the cold air flow. This method of reducing the air outlet area effectively increases the pressure of the cold air, resulting in a stronger and more powerful cold air flow that can travel further. Therefore, in outdoor environments such as coffee shops, by concentrating the cold air in a certain direction, users can enjoy a better experience of receiving cool air, making it more suitable for outdoor environments with high humidity and high heat.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the air outlet ball 270 includes an air outlet seat 271 and a ball 272. The air outlet seat 271 is inserted into the mounting hole 261, and the ball 272 is rotatably mounted on the air outlet seat 271. A through hole 2721 is provided on the ball 272. When the ball 272 is subjected to force and rotates relative to the air outlet seat 271, the orientation of the through hole 2721 is adjustable.

[0037] It should be noted that the above structure is designed to facilitate adjustment of the direction of the cold air blowing. Specifically, the air outlet base 271 is fitted and installed within the mounting hole 261. The sphere 272 is rotatably installed within the air outlet base 271, and a through hole 2721 is provided on the sphere 272. Thus, when the sphere 272 is subjected to force and rotates relative to the air outlet base 271, the through hole 2721 can be oriented in any direction. One end of the through hole 2721 communicates with the interior of the air collection shell 260. In this way, after the air is cooled by the evaporator 210, it is blown out directionally through the through hole 2721. The outdoor portable air conditioner 10 of this application can provide a stable large volume of cold air in high humidity and high temperature environments such as outdoors, thus providing a better user experience in high temperature and high humidity outdoor environments.

[0038] like Figure 1 As shown, in one embodiment, a dustproof net 700 is provided on the first inlet 120.

[0039] It should be noted that outdoor air is mostly covered with a large number of dust particles, especially shops near the street, where the amount of dust and small solid particles is relatively large. In order to prevent debris from entering the heat exchange components, especially the evaporator 210, which would cause bacteria to grow in the evaporator 210, a dustproof net 700 is installed on the first inlet 120 to isolate the inside of the cabinet 100 from dust.

[0040] like Figure 1 As shown, in one embodiment, a number of casters 800 are spaced apart on the bottom of the cabinet 100.

[0041] For example, four casters 800 are provided, located at the four corners of the bottom of the cabinet 100, which makes the cabinet 100 easy and quick to move outdoors and convenient to use.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
