Description

A portable air conditioner Technical Field

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

[0002] Currently, residential and commercial air conditioners are generally divided into cooling-only and cooling-and-heating types. When operating in cooling mode, an air conditioner can lower the indoor temperature or dehumidify; when operating in heating mode, it can raise the indoor temperature. Sometimes, dehumidification without lowering the temperature is needed, such as in rainy, humid weather or other projects requiring heating for dehumidification. Furthermore, because the condenser and evaporator are flat and the fan is round, the airflow is not smooth, affecting the performance.

[0003] For example, Chinese utility model patent with announcement number CN2653353Y discloses an integrated portable air conditioner, which includes an evaporator, a compressor, and a condenser connected in series through pipes. It also includes an auxiliary heat exchanger to achieve the function of cooling or dehumidifying without cooling. It does not have a heating function and does not involve the specific structure of the portable air conditioner.

[0004] Utility Model Content

[0005] The purpose of this application embodiment is to provide a portable air conditioner, including a housing and an air duct system, a refrigeration system and a heating system disposed within the housing. The air duct system includes an air inlet, a first air outlet and a first fan. The air inlet and the first air outlet are respectively disposed on the housing, and the first fan is disposed between the air inlet and the first air outlet.

[0006] The refrigeration system includes a refrigerant pipeline and a compressor, a solenoid valve, a first condenser, a second condenser and an evaporator connected in series on the refrigerant pipeline. The evaporator and the second condenser are both arc-shaped and are arranged around the first fan and opposite to the first air outlet.

[0007] The heating system includes a heating element, which is disposed between the second condenser and the first fan;

[0008] In this process, indoor air enters through the air inlet under the action of the first fan, is cooled by the evaporator to become cold air, and is discharged into the room through the first air outlet.

[0009] Alternatively, indoor air enters through the air inlet under the action of the first fan, is heated by the heating element to become hot air, and is discharged into the room through the first air outlet;

[0010] Alternatively, indoor air enters through the air inlet under the action of the first fan, cools and condenses into moisture in the evaporator, then heats up in the second condenser to become dry air, and is discharged into the room through the first air outlet. This application, through its duct system, refrigeration system, and heating system, can achieve cooling, heating, and dehumidification functions without cooling, meeting the needs of different seasons and environments.

[0011] As an optional embodiment, the air duct system further includes a second air outlet and a second fan. The second air outlet is disposed on the housing and located below the air inlet, and the second fan is disposed inside the housing and opposite to the second air outlet.

[0012] In this system, indoor air enters through the air inlet under the action of the second fan to cool the first condenser, and is then exhausted into the room through the second air outlet. This application adds a second air outlet and a second fan, which helps to improve air circulation efficiency and cooling effect.

[0013] As an optional embodiment, the portable air conditioner further includes a water tank and a water curtain. The water tank is located inside the casing and opposite to the compressor. The water curtain is located outside the first condenser. The water curtain is connected to the water tank through a pipeline so that water in the water tank is transported to the water curtain to cool the first condenser.

[0014] In this system, indoor air enters through the air inlet under the action of the second fan, absorbs heat through the water curtain, and becomes cold air to cool the first condenser before being discharged into the room through the second air outlet. This application provides an additional cooling method through the arrangement of a water tank and a water curtain, using the evaporation of the water curtain to lower the temperature of the first condenser and enhance the cooling effect.

[0015] As an optional embodiment, a spray device connected to the water tank is provided inside the first air outlet. The spray device is used to humidify the air discharged from the first air outlet into the room. This application provides a humidification function to improve indoor air quality, especially in dry environments, which helps to enhance user comfort.

[0016] As an optional embodiment, a rotatable sweeping fan blade is provided inside the first air outlet, and the sweeping fan blade is used to adjust the airflow direction of the gas discharged from the first air outlet into the room. This application provides an airflow adjustment function, allowing users to adjust the direction of the air conditioning airflow as needed, improving the flexibility and comfort of use.

[0017] As an optional embodiment, the portable air conditioner further includes a water receiving tank located below the evaporator and connected to the water tank. This tank receives condensate from the outer wall of the evaporator and transfers it to the water tank. This application's method of receiving condensate from the outer wall of the evaporator via a water receiving tank and transferring it to the water tank for collection and reuse helps conserve water resources and reduce water waste.

[0018] As an optional embodiment, the first fan is positioned close to the first air outlet, and an air guide shroud is provided inside the housing. The air guide shroud is used to direct the gas introduced by the first fan to the first air outlet.

[0031] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be considered as limiting, but merely as an example of embodiments. Other modifications within the scope and spirit of this application will be apparent to those skilled in the art.

[0032] The accompanying drawings, which are included in and form part of this specification, illustrate embodiments of the present application and, together with the general description of the present application given above and the detailed description of the embodiments given below, serve to explain the principles of the present application.

[0033] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0034] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application.

[0035] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0036] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0037] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0038] This application provides a portable air conditioner, as shown in Figures 1-5, including a housing 0 and an air duct system, a refrigeration system and a heating system disposed within the housing 0.

[0039] As shown in Figures 1 and 2, the air duct system includes an air inlet 17, a first air outlet 16, and a first fan 13. The air inlet 17 and the first air outlet 16 are respectively disposed on the housing 0, and the first fan 13 is disposed between the air inlet 17 and the first air outlet 16. The air inlet 17 is located on a first side of the housing 0, and the first air outlet 16 is located on the other side of the housing 0.

[0040] The refrigeration system includes a refrigerant pipe 8 and a compressor 1, a solenoid valve 5, a first condenser 2, a second condenser 11, and an evaporator 10, which are sequentially connected in series on the refrigerant pipe 8. The evaporator 10 and the second condenser 11 are both arc-shaped and are arranged around the first fan 13 and opposite to the first air outlet 16. The compressor 1 is mounted on the base of the housing 0.

[0041] The second condenser 11 and the evaporator 10 are both approximately U-shaped plate structures. The arc-shaped structure can increase the heat exchange area of ​​the evaporator 10 and the second condenser 11, which is beneficial to improving working efficiency and makes the structure more compact and easier to lay out.

[0042] The heating system includes a heating element 12, which is disposed between the second condenser 11 and the first fan 13. The heating element 12 has a plate-like structure, and its centerline is collinear with the axis of the first fan 13.

[0043] In this system, indoor air enters through the air inlet 17 under the action of the first fan 13, is cooled by the evaporator 10 to become cold air, and is then exhausted into the room through the first air outlet 16 to achieve air conditioning cooling. Alternatively, indoor air enters through the air inlet 17 under the action of the first fan 13, is heated by the heating element 12 to become hot air, and is then exhausted into the room through the first air outlet 16 to achieve air conditioning heating.

[0044] In addition, because the dehumidification of existing air conditioners is done during the cooling process, there are two problems with this method. First, when the room temperature is below 15 degrees Celsius, dehumidification will cause the evaporator to frost and ice up, blocking air circulation and resulting in poor dehumidification effect. Second, in the warm and humid weather of the south (the return of spring), the outdoor air temperature and humidity are both high, and the indoor cooling will cause indoor water vapor to condense faster, resulting in more water droplets on the indoor walls, which is also ineffective.

[0045] Therefore, the portable air conditioner of this application also has the function of dehumidifying without cooling. The indoor air enters through the air inlet 17 under the action of the first fan 13, cools down and condenses the water through the evaporator 10, and then heats up through the second condenser 11 to become dry air, and is discharged into the room through the first air outlet 16.

[0046] The portable air conditioner of this application draws in indoor air through an air duct system. Depending on the user's needs, it can select cooling, heating, or dehumidification modes without cooling, so that the portable air conditioner can adapt to different environments and user needs and provide comfortable indoor conditions.

[0047] This application, while achieving heating, cooling, and dehumidification functions without cooling, designs the second condenser 11 and evaporator 10 in an arc shape, resulting in a reasonable structural design, compact layout, and space saving. Furthermore, the placement of the second condenser 11 and evaporator 10, in conjunction with the first fan 13, forms a streamlined airflow duct, ensuring smooth airflow and high heat exchange efficiency.

[0048] As an optional embodiment, as shown in FIG1, the air duct system further includes a second air outlet 18 and a second fan 4. The second air outlet 18 is disposed on the housing 0 and located below the air inlet 17, and the second fan 4 is disposed inside the housing 0 and opposite to the second air outlet 18.

[0049] In this system, indoor air enters through the air inlet 17 under the action of the second fan 4 to cool the first condenser 2, and is then exhausted into the room through the second air outlet 18. This application adds a second air outlet 18 and a second fan 4, which helps to improve air circulation efficiency and cooling effect.

[0050] As an optional embodiment, the portable air conditioner further includes a water tank 6 and a water curtain 3. The water tank 6 is located inside the housing 0 and opposite to the compressor 1. The water curtain 3 is located outside the first condenser 2. The water curtain 3 is connected to the water tank 6 through a pipeline so that the water in the water tank 6 is transported to the water curtain 3 to cool the first condenser 2.

[0051] In this system, indoor air enters through the air inlet 17 under the action of the second fan 4, absorbs heat through the water curtain 3, and becomes cold air to cool the first condenser 2 before being discharged into the room through the second air outlet 18. This application provides an additional cooling method through the arrangement of the water tank 6 and the water curtain 3, using the evaporation of the water curtain 3 to lower the temperature of the first condenser 2 and enhance the cooling effect.

[0052] As an optional embodiment, a spray device 14 connected to the water tank 6 is provided inside the first air outlet 16. The spray device 14 is used to humidify the air discharged from the first air outlet 16 into the room. This application provides a humidification function to improve indoor air quality, especially in dry environments, which helps to enhance user comfort.

[0053] As an optional embodiment, a rotatable sweeping fan blade 15 is provided inside the first air outlet 16. The sweeping fan blade 15 is used to adjust the airflow direction of the gas discharged from the first air outlet 16 into the room. This application provides an airflow direction adjustment function, allowing users to adjust the direction of the air conditioning airflow as needed, improving the flexibility and comfort of use.

[0054] As an optional embodiment, the portable air conditioner further includes a water receiving tank 9, which is located below the evaporator 10 and connected to the water tank 6. The water receiving tank 9 receives condensate from the outer wall of the evaporator 10 and transports it to the water tank 6. This application's method of receiving condensate from the outer wall of the evaporator 10 via the water receiving tank 9 and transporting it to the water tank 6 for collection and reuse helps to conserve water resources and reduce water waste.

[0055] As an optional embodiment, the first fan 13 is positioned close to the first air outlet 16, and an air guide shroud 19 is provided inside the housing 0. The air guide shroud 19 is used to guide the gas introduced by the first fan 13 to the first air outlet 16. This application optimizes the airflow path and improves air conditioning efficiency through the design of the air guide shroud 19, ensuring that cold or hot air is more effectively distributed to the indoor space.

[0056] As an optional embodiment, the refrigerant pipe 8 includes a main pipe 81, a first branch pipe 82, a second branch pipe 83, a third branch pipe 84, and a recovery pipe 85. The first branch pipe 82 passes through the first condenser 2, the second branch pipe 83 passes through the second condenser 11, and the third branch pipe 84 passes through the evaporator 10.

[0057] One end of the main pipe 81 is connected to the outlet of the compressor 1, and the other end of the main pipe 81 is connected to the inlet of the solenoid valve 5. The first outlet of the solenoid valve 5 is connected to one end of the first branch pipe 82, and the other end of the first branch pipe 82 is connected to one end of the third branch pipe 84. The second outlet of the solenoid valve 5 is connected to one end of the second branch pipe 83, and the other end of the second branch pipe 83 is connected to one end of the third branch pipe 84. The other end of the third branch pipe 84 is connected to one end of the recovery pipe 85, and the other end of the recovery pipe 85 is connected to the inlet of the compressor 1. The refrigerant piping 8 of this application has a reasonable layout, which helps to improve the overall performance of the air conditioner.

[0058] As an optional embodiment, the end of the third branch pipe 84 furthest from the recovery pipe 85 is provided with a capillary tube 7, and the other end of the capillary tube 7 is connected to the other end of the first branch pipe 82 and the other end of the second branch pipe 83, respectively. The design of the capillary tube 7 in this application helps to control the flow rate of the refrigerant, thereby improving the stability and efficiency of the system.

[0059] When the portable air conditioner of this application is cooling, as shown in Figure 3, the refrigerant is transformed into a high-temperature and high-pressure gas by the compressor 1, and then transported to the solenoid valve 5 through the main pipe 81. The solenoid valve 5 connects the refrigerant to the first condenser 2 through the first branch pipe 82.

[0060] The second fan 4 is activated to cool the first condenser 2. The air inlet 17 of the second fan 4 is equipped with a water curtain 3, which can further cool the first condenser 2. The cooled refrigerant enters the third branch pipe 84 through the capillary tube 7, and then flows into the evaporator 10 as a low-pressure, low-temperature liquid.

[0061] When outdoor air is introduced by the first fan 13 and flows through the evaporator 10, the indoor air is rapidly cooled and then blown out from the air outlet under the guidance of the air guide shroud 19. If the user needs to adjust the direction of the cooled airflow, the sweeping fan blades 15 can be adjusted.

[0062] In addition, as air flows through the evaporator 10, some moisture in the air is carried away by the evaporator 10, making the air dry. Therefore, a spray device 14 connected to the water tank 6 is added to the first air outlet 16 to humidify the air.

[0063] When the portable air conditioner of this application is dehumidifying, as shown in Figure 4, the refrigerant is transformed into a high-temperature and high-pressure gas by the compressor 1, and then transported to the solenoid valve 5 through the main pipe 81. The solenoid valve 5 connects the refrigerant to the second condenser 11 through the second branch pipe 83.

[0064] The first fan 13 is started to cool the second condenser 11. The cooled refrigerant enters the third branch pipe 84 through the capillary tube 7, and then becomes a low-pressure, low-temperature liquid that flows into the evaporator 10.

[0065] When outdoor air is introduced by the first fan 13 and flows through the evaporator 10, the indoor air cools rapidly. A large amount of condensate is then generated on the outer wall of the evaporator 10. The condensate drips into the water collection tank 9 under gravity and is then collected into the water tank 6. At this point, the air absorbs heat and heats up through the second condenser 11 before being blown out from the first air outlet 16, achieving constant temperature dehumidification.

[0066] This application uses a separate air duct for constant temperature dehumidification, condenses cold air for dehumidification, then heats the condensed cold air through a second condenser 11 before blowing it into the room. This method has high dehumidification efficiency and can precisely control indoor humidity and temperature, creating a comfortable environment.

[0067] When the portable air conditioner of this application is heating, as shown in Figure 5, the indoor temperature is low in winter, so the heating element 12 is used to heat the air. When the first fan 13 is turned on, indoor air is introduced into the casing 0 and flows through the heating element 12 to be heated to form hot air, which is then blown out from the first air outlet 16.

[0068] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
