Description

Technical Field

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

[0002] Portable air conditioners in related technologies are classified into single-duct portable air conditioners and dual-duct portable air conditioners based on the number of ducts. A dual-duct portable air conditioner has two ducts: an intake duct and an exhaust duct. The intake duct draws in fresh air from the outside, cools it through the indoor heat exchanger inside the air conditioner, and then delivers it into the room; the exhaust duct expels hot air from the room to the outside.

[0003] For portable air conditioners with a dual-duct structure, when air is drawn in through the air inlet duct on the lower outdoor duct, the air can be directed to the outdoor heat exchanger on the lower side. However, the air directly passing through the air inlet duct on the lower side of the portable air conditioner passes through the outdoor heat exchanger in an overly concentrated manner. This results in uneven heat exchange, leading to low heat exchange efficiency and affecting user comfort. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a portable air conditioner that has advantages such as optimized airflow uniformity and improved heat exchange efficiency.

[0005] A portable air conditioner according to a first aspect of the present invention includes: a housing, the housing being internally divided into an indoor cavity and an outdoor cavity, the indoor cavity having an indoor air inlet and an indoor air outlet, and the outdoor cavity having an outdoor air inlet and an outdoor air outlet; an indoor fan disposed within the indoor cavity, the indoor fan driving airflow from the indoor air inlet to the indoor air outlet when operating; an indoor heat exchanger disposed within the indoor cavity for exchanging heat with the airflow within the indoor cavity; and an outdoor fan disposed within the outdoor cavity. Inside, when the outdoor fan is running, it drives airflow from the outdoor air inlet to the outdoor air outlet; an outdoor heat exchanger is disposed in the outdoor cavity and is used to exchange heat with the airflow in the outdoor cavity; a guide shell is constructed between the outdoor air inlet and the outdoor heat exchanger; wherein, the guide shell has a guide inlet and a guide outlet, the guide inlet is connected to the inner side wall where the outdoor air inlet is located, the guide outlet is connected to the edge of the outdoor heat exchanger, and the guide shell forms a closed buffer cavity between the outdoor air inlet and the outdoor heat exchanger.

[0006] According to the portable air conditioner of this embodiment, the closed buffer cavity formed by the air guide shell optimizes the airflow direction before it enters the outdoor heat exchanger. The air guide shell ensures that the air entering the outdoor cavity is evenly distributed within a closed buffer cavity, preventing direct high-speed impact on the outdoor heat exchanger. This not only improves the heat exchange efficiency between the outdoor heat exchanger and the air but also avoids energy waste caused by localized overheating or overcooling. Simultaneously, guiding the airflow to the outdoor heat exchanger through the air guide shell reduces unnecessary air resistance, resulting in smoother airflow. This optimized airflow path helps improve the overall heat exchange efficiency, thereby enhancing the overall performance of the portable air conditioner.

[0007] The portable air conditioner according to the present invention has advantages such as optimized air intake uniformity and improved heat exchange efficiency.

[0008] According to some embodiments of the present invention, the outdoor heat exchanger includes: an outdoor heat exchanger body, the outdoor heat exchanger body being installed in the outdoor cavity; a first end plate and a second end plate, the first end plate and the second end plate being respectively connected to opposite sides in the width direction of the outdoor heat exchanger body, the first end plate being connected to one side wall of the air guide shell, and the second end plate being connected to the other side wall of the air guide shell.

[0009] The above solution has the following advantages or beneficial effects: the first end plate and the second end plate are respectively connected to both sides of the outdoor heat exchanger body in the width direction, forming a closed structure of the outdoor heat exchanger. The first end plate and the second end plate are each connected to one side wall of the air guide shell, ensuring a tight connection between the outdoor heat exchanger and the air guide shell, forming a guiding channel for air circulation.

[0010] According to some embodiments of the present invention, the first end plate is configured with a first flange folded toward one side wall of the air guide housing, and the second end plate is configured with a second flange folded toward the other side wall of the air guide housing. The air guide housing is configured with a receiving groove for accommodating the first flange and the second flange, and a first limiting edge covering the opening of the receiving groove is configured on the side of the air guide housing adjacent to the first flange, and a second limiting edge covering the opening of the receiving groove is configured on the side of the air guide housing adjacent to the second flange. The first limiting edge stops at the first flange, and the second limiting edge stops at the second flange.

[0011] The above solution has the following advantages or beneficial effects: the folding of the first and second flanges onto the side wall of the air guide housing helps to enhance the sealing between the outdoor heat exchanger and the air guide housing. The first and second limiting edges act as stops and fixations for the first and second flanges, preventing displacement of the first and second flanges during operation, ensuring the integrity and stability of the buffer cavity structure, and also enhancing the overall reliability of the portable air conditioner.

[0012] According to some embodiments of the present invention, there are multiple first limiting edges, which are spaced apart along the length direction of the receiving groove where the first flange is located; there are multiple second limiting edges, which are spaced apart along the length direction of the receiving groove where the second flange is located.

[0013] The above solution has the following advantages or beneficial effects: multiple first limiting edges and multiple second limiting edges can provide a more uniform contact surface between the outdoor heat exchanger and the air guide shell, so that the pressure distribution of the first flange and the second flange during operation is more uniform, reducing the deformation or damage caused by stress concentration, and improving the overall stability of the buffer cavity structure.

[0014] According to some embodiments of the present invention, one end of the first limiting edge and the second limiting edge in the length direction is provided with a guide edge, and the guide edge extends obliquely outward of the receiving groove so that the first flange and the second flange enter the receiving groove.

[0015] The above solution has the following advantages or beneficial effects: the inclined structure of the guide edge can guide the first and second flanges to enter the receiving groove more smoothly. This guiding effect can reduce human error in the assembly process, improve assembly efficiency, and reduce production complexity.

[0016] According to some embodiments of the present invention, the first flange and the second flange are both folded in the same direction, and the first limiting edge and the second limiting edge both extend in the opposite direction to the first flange.

[0017] The above solution has the following advantages or beneficial effects: The above structure ensures that the outdoor heat exchanger and the air guide shell are installed in the same direction during the assembly process, making the assembly process more intuitive and simple, and reducing the probability of assembly errors.

[0018] According to some embodiments of the present invention, the distance between the buffer cavity and the outdoor heat exchanger and the outdoor air inlet is not less than 20mm.

[0019] The above solution has the following advantages or beneficial effects: The space of the buffer chamber is the distance between the outdoor heat exchanger and the outdoor air inlet. A sufficiently large distance allows the air entering from the outdoor air inlet to have more space to diffuse after entering the buffer chamber, promoting the uniform distribution of airflow and ensuring that the air does not cause uneven airflow due to inertia when entering the room, which helps to improve the overall cooling effect of the portable air conditioner.

[0020] According to some embodiments of the present invention, the indoor fan and the outdoor fan are driven by a drive motor. The upper space of the housing forms the indoor cavity, and the lower space of the housing forms the outdoor cavity. The drive motor is located between the indoor cavity and the outdoor cavity. The drive motor is equipped with a motor shaft. One end of the motor shaft is connected to the indoor fan, and the other end of the motor shaft is connected to the outdoor fan.

[0021] The above solution has the following advantages or beneficial effects: the drive motor simultaneously powers both the indoor and outdoor fans, enabling them to work in coordination and ensuring smooth air circulation and effective heat exchange. Driving both the indoor and outdoor fans with a single drive motor not only simplifies the mechanical structure and reduces potential failure points but also improves energy efficiency.

[0022] According to some embodiments of the present invention, the indoor air inlet, the outdoor air inlet, and the indoor air outlet all face the same side of the housing.

[0023] The above solution offers the following advantages or benefits: Since the indoor air inlet, outdoor air inlet, and indoor air outlet all face the same side of the casing, the overall structure of the portable air conditioner can be made more compact, reducing the lateral space required for the equipment. This helps to better arrange portable air conditioners in environments with limited space (such as small apartments, offices, or mobile spaces).

[0024] According to some embodiments of the present invention, in the front-rear direction, the size of the indoor cavity is smaller than the size of the outdoor cavity, the front surface of the housing is flush, and the portion of the outdoor cavity of the housing extends rearward beyond the portion of the indoor cavity of the housing.

[0025] The above solution has the following advantages or beneficial effects: the indoor cavity and the outdoor cavity are of different thicknesses and are staggered, which facilitates the separation and installation of internal components.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

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.

[0049] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0050] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0051] The portable air conditioner 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0052] like Figures 1-11 As shown, the portable air conditioner 1 according to an embodiment of the present utility model includes a housing 100, an indoor fan 310, an outdoor fan 320, an outdoor heat exchanger 400, and an indoor heat exchanger 500.

[0053] The casing 100 is internally divided into an indoor cavity 110 and an outdoor cavity 120. The indoor cavity 110 has an indoor air inlet 111 and an indoor air outlet 112, while the outdoor cavity 120 has an outdoor air inlet 121 and an outdoor air outlet 122. The compressor is installed inside the outdoor cavity 120. An indoor fan 310 is located inside the indoor cavity, and when the indoor fan is running, it drives airflow from the indoor air inlet to the indoor air outlet. An indoor heat exchanger 500 is located inside the indoor cavity 110 and is used for heat exchange with the airflow inside the indoor cavity 110. An outdoor fan 320 is located inside the outdoor cavity 120, and when the outdoor fan 320 is running, it drives airflow from the outdoor air inlet 121 to the outdoor air outlet 122. An outdoor heat exchanger 400 is located inside the outdoor cavity 120 and is used for heat exchange with the airflow inside the outdoor cavity 120.

[0054] The air guide housing 130 has an air guide inlet 131 and an air guide outlet 132. The air guide inlet 131 is connected to the inner wall where the outdoor air inlet 111 is located, and the air guide outlet 132 is connected to the edge of the outdoor heat exchanger 400. The air guide housing 130 forms a closed buffer cavity 133 between the outdoor air inlet 121 and the outdoor heat exchanger 400.

[0055] For example, the air guide housing 130 is configured as a closed structure to form a buffer cavity 133 for a specific air guide path, forming a closed air intake channel along the air intake direction. The air guide housing 130 can be formed on the housing 100, or it can be a separate housing structure constructed inside the housing 100. One side of the air guide housing 130 forms an air guide inlet 131 and the other side forms an air guide outlet 132.

[0056] According to the embodiment of the present invention, the mobile air conditioner 1 has a closed buffer cavity 133 formed by the air guide housing 130, which allows air to flow from the air guide inlet 131 to the air guide outlet 132. A specific air flow path is formed inside the air guide housing 130, and the flow direction through the air guide housing 130 before entering the outdoor heat exchanger 400 is optimized.

[0057] Furthermore, a certain distance is formed between the air inlet 131 and the air outlet 132. The air guide shell 130 ensures that the air entering the outdoor cavity 120 is first evenly distributed within a closed buffer chamber 133. The air from the outdoor air inlet 121 is evenly diffused through the air guide shell 130, resulting in more uniform airflow to the outdoor heat exchanger 400. This ensures that the air does not directly impact the outdoor heat exchanger 400 at high speed, but rather contacts the surface of the outdoor heat exchanger 400 in a gentler and more uniform manner. This not only improves the heat exchange efficiency between the outdoor heat exchanger 400 and the air, but also avoids energy waste caused by local overheating or overcooling. At the same time, guiding the airflow to the outdoor heat exchanger 400 through the air guide shell 130 reduces unnecessary air resistance and makes the airflow smoother. This optimized airflow path helps improve the heat exchange efficiency of the entire portable air conditioner, thereby enhancing the overall performance of the portable air conditioner 1.

[0058] Therefore, the portable air conditioner 1 according to the present invention has advantages such as optimized air intake uniformity and improved heat exchange efficiency.

[0059] Furthermore, without the air guide shell, the direct and rapid entry of outside air into and impacting the outdoor heat exchanger 400 could generate significant noise. However, with the buffer chamber 133 formed by the air guide shell 130, the air first enters the buffer chamber 133 for deceleration and uniform flow, thus reducing the noise generated by air impact.

[0060] In some optional embodiments of this utility model, such as Figure 6 and Figure 8 As shown, the outdoor heat exchanger 400 includes an outdoor heat exchanger body 410, a first end plate 420, and a second end plate 430. The outdoor heat exchanger body 410 is installed inside the outdoor cavity 120. The first end plate 420 and the second end plate 430 are respectively connected to opposite sides of the outdoor heat exchanger body 410 in the width direction. The first end plate 420 is connected to one side wall of the air guide housing 130, and the second end plate 430 is connected to the other side wall of the air guide housing 130.

[0061] The outdoor heat exchanger body 410 is typically composed of fins and pipes, which effectively increases the heat exchange area to improve cooling or heating efficiency. A first end plate 420 and a second end plate 430 are respectively connected to both sides of the outdoor heat exchanger body 410 in the width direction, forming a closed structure of the outdoor heat exchanger 400. The first end plate 420 and the second end plate 430 are each connected to one side wall of the air guide housing 130, ensuring a tight connection between the outdoor heat exchanger 400 and the air guide housing 130, forming a guiding channel for airflow. The air guide housing 130 surrounds the outdoor heat exchanger body 410, guiding airflow and ensuring smooth airflow through the outdoor heat exchanger 400, thereby improving the heat exchange efficiency inside the portable air conditioner 1.

[0062] In some optional embodiments of this utility model, such as Figures 5-7 As shown, the first end plate 420 is constructed with a first flange 421 folded towards one side wall of the air guide housing 130, and the second end plate 430 is constructed with a second flange 431 folded towards the other side wall of the air guide housing 130. The air guide housing 130 is constructed with a receiving groove 134 for accommodating the first flange 421 and the second flange 431. A first limiting edge 135 covering the opening of the receiving groove 134 is constructed on the side of the air guide housing 130 adjacent to the first flange 421, and a second limiting edge 136 covering the opening of the receiving groove 134 is constructed on the side of the air guide housing 130 adjacent to the second flange 431. The first limiting edge 135 stops at the first flange 421, and the second limiting edge 136 stops at the second flange 431.

[0063] The folding of the first flange 421 and the second flange 431 onto the side wall of the air guide housing 130 helps to enhance the sealing between the outdoor heat exchanger 400 and the air guide housing 130. This sealing effectively prevents air leakage and reduces the impact of external air on the cooling effect of the outdoor heat exchanger 400, thereby improving cooling or heating efficiency.

[0064] The first limiting edge 135 and the second limiting edge 136 stop and fix the first flange 421 and the second flange 431, preventing the first flange 421 and the second flange 431 from shifting during operation, ensuring the integrity and stability of the buffer cavity 133's neat structure, and also enhancing the overall reliability of the portable air conditioner 1.

[0065] Furthermore, the first flange 421 and the second flange 431 simplify the assembly process between the outdoor heat exchanger 400 and the air guide housing 130, making installation more convenient and quick. At the same time, the structure of the first limiting edge 135 and the second limiting edge 136 also facilitates future maintenance, ensuring that the portable air conditioner 1 can be easily disassembled when maintenance is required.

[0066] In some optional embodiments of this utility model, such as Figures 5-10 As shown, there are multiple first limiting edges 135, which are spaced apart along the length of the receiving groove 134 where the first flange 421 is located. There are multiple second limiting edges 136, which are spaced apart along the length of the receiving groove 134 where the second flange 431 is located.

[0067] Multiple first limiting edges 135 and multiple second limiting edges 136 provide a more uniform contact surface between the outdoor heat exchanger 400 and the air guide housing 130, resulting in a more uniform pressure distribution on the first flange 421 and the second flange 431 during operation. This reduces deformation or damage caused by stress concentration and improves the overall structural stability of the buffer cavity 133. The stopping action of the multiple first limiting edges 135 and multiple second limiting edges 136 on the first flange 421 and the second flange 431 effectively prevents displacement of the first flange 421 and the second flange 431 during operation due to factors such as vibration and temperature changes, ensuring the normal operation of the portable air conditioner 1.

[0068] In some optional embodiments of this utility model, such as Figure 10 and Figure 11 As shown, one end of the first limiting edge 135 and the second limiting edge 136 along the length direction is provided with a guide edge 137. The guide edge 137 extends obliquely outward of the receiving groove 134 so that the first flange 421 and the second flange 431 enter the receiving groove 134.

[0069] The inclined structure of the guide edge 137 guides the first flange 421 and the second flange 431 to enter the receiving groove 134 more smoothly. This guiding effect reduces human error during assembly, improves assembly efficiency, and reduces production complexity. Simultaneously, due to the presence of the guide edge 137, the first flange 421 and the second flange 431 avoid direct impact with the groove wall when entering the receiving groove 134, thereby reducing the risk of damage that may occur during assembly, including deformation or damage to the first flange 421 and the second flange 431, and improving the integrity of the assembly. Furthermore, the guide edge 137 helps maintain the correct alignment of the first flange 421 and the second flange 431 when entering the receiving groove 134, ensuring that the first flange 421 and the second flange 431 are smoothly and accurately positioned.

[0070] In some optional embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the first flange 421 and the second flange 431 are both folded in the same direction, and the first limiting edge 135 and the second limiting edge 136 both extend in the opposite direction to the first flange 421.

[0071] The aforementioned structure ensures that the outdoor heat exchanger 400 and the air guide shell 130 are installed in the same direction during assembly, making the assembly process more intuitive and simple, and reducing the probability of assembly errors. Due to the unified installation direction of the components, workers can complete the assembly operation more quickly, saving time and improving production efficiency.

[0072] In some optional embodiments of this utility model, the distance between the buffer cavity 133 and the outdoor heat exchanger 400 and the outdoor air inlet 121 is not less than 20mm.

[0073] The space of the buffer chamber 133, which is the distance between the outdoor heat exchanger 400 and the outdoor air inlet 121, requires a sufficiently large distance to allow the air entering from the outdoor air inlet duct 101 more space to diffuse after entering the buffer chamber 133. This promotes a uniform airflow distribution and ensures that the airflow is not uneven due to inertia when entering the room, thus helping to improve the overall cooling effect of the portable air conditioner 1. At the same time, a larger buffer distance helps to reduce sudden changes in wind speed, thereby reducing noise caused by rapid changes in airflow. When the airflow passes through the buffer chamber 133, the wind speed will slow down, reducing the noise generated by air friction, making the portable air conditioner 1 quieter during operation and improving user comfort.

[0074] In some optional embodiments of this utility model, such as Figure 4 As shown, the indoor fan 310 and the outdoor fan 320 are driven by the drive motor 330. The upper space of the housing 100 forms the indoor cavity 110, and the lower space of the housing 100 forms the outdoor cavity 120. The drive motor 330 is located between the indoor cavity 110 and the outdoor cavity 120. The drive motor 330 is equipped with a motor shaft. One end of the motor shaft is connected to the indoor fan 310, and the other end of the motor shaft is connected to the outdoor fan 320.

[0075] The indoor fan 310 can be a cross-flow fan, and the outdoor fan 320 can be a centrifugal fan. The indoor fan 310 draws in indoor air through the indoor air inlet 111 and pushes it through the indoor heat exchanger 500 for cooling or heating. Then, the treated air is returned to the room through the indoor air outlet. Through effective air circulation, the indoor fan 310 helps maintain a comfortable indoor environment. The outdoor fan 320 draws in outdoor air through the outdoor air inlet 122 and pushes it through the outdoor heat exchanger 400 for cooling, improving heat dissipation efficiency and effectively reducing the refrigerant temperature, thus ensuring the efficient operation of the air conditioning circulation system.

[0076] The drive motor 330 simultaneously powers both the indoor fan 310 and the outdoor fan 320, enabling them to work in coordination to ensure smooth air circulation and effective heat exchange. By using a single drive motor 330 to drive both the indoor fan 310 and the outdoor fan 320, compared to the structure in conventional portable air conditioners where the indoor and outdoor fans are driven by separate motors, not only are fewer components saved, the mechanical structure simplified, and the product size reduced, thus lowering product costs, but the failure rate is also reduced, further improving product reliability.

[0077] In some optional embodiments of this utility model, such as Figures 1-4 As shown, the indoor air inlet 111, the outdoor air inlet 121, and the indoor air outlet 122 all face the same side of the casing 100.

[0078] Since the indoor air inlet 111, the outdoor air inlet 121, and the indoor air outlet 122 all face the same side of the casing 100, the overall structure of the portable air conditioner 1 can be made more compact, reducing the lateral space required by the device. This helps to better arrange the portable air conditioner 1 in environments with limited space (such as small apartments, offices, or mobile spaces). At the same time, this layout reduces the space wasted by the dispersed air outlets, allowing the portable air conditioner 1 to be placed closer to walls or other furniture, making full use of available space.

[0079] In some optional embodiments of this utility model, such as Figures 1-4 As shown, in the front-rear direction, the size of the indoor cavity 110 is smaller than the size of the outdoor cavity 120, the front surface of the housing 100 is flush, and the portion of the outdoor cavity 120 of the housing 100 extends rearward beyond the portion of the indoor cavity 110 of the housing 100.

[0080] The indoor cavity 110 and the outdoor cavity 120 are of different thicknesses and staggered, which facilitates the separation and installation of internal components. For example, the outdoor cavity 120 is thicker and can accommodate heat-generating components such as the outdoor heat exchanger 400 and the outdoor fan 320. The thicker structure provides these components with more installation space and ventilation channels, which is conducive to the rapid removal of heat.

[0081] In some alternative embodiments, refer to Figure 10 The top of the buffer chamber 133 is provided with a water receiving trough 103, which can receive all the condensate discharged from the indoor heat exchanger 500. The water receiving trough 103 is provided with "V"-shaped water guiding ribs 104 to facilitate the flow of condensate. Drain holes 105 are provided on both sides of the water receiving trough 103. When condensate enters the water receiving trough 103 of the buffer chamber 133, it is guided by the water guiding ribs 104 to the drain holes 105, so that the condensate can flow more evenly to the outdoor heat exchanger 400 to assist the outdoor heat exchanger 400 in heat dissipation.

[0082] Other components and operations of the portable air conditioner 1 according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0083] In this application, the portable air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0084] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0085] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0086] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit. The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger functions as a condenser, the air conditioner acts as a heater in heating mode; when it functions as an evaporator, it acts as a cooler in cooling mode.
