Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to a portable air conditioner that integrates drying and preservation. Background Technology

[0002] In cooling mode, the exhaust temperature from the bottom vent of a portable air conditioner can reach 30–60°C; while in heating mode, the exhaust temperature can reach 10–20°C. This heat could be utilized. However, currently, regardless of whether it's a cooling-only or heat pump type, the hot / cold air discharged from the bottom vent after heat exchange with the condenser / evaporator is directly discharged into the air through the exhaust pipe, resulting in waste. Summary of the Invention

[0003] The first objective of this invention is to provide a portable air conditioner that integrates drying and preservation to solve the technical problem of low energy efficiency in existing portable air conditioners.

[0004] The present invention provides a portable air conditioner integrating drying and preservation, comprising a housing, wherein a first heat exchange chamber, a second heat exchange chamber, and a storage chamber are provided within the housing. The housing has a first air inlet, a second air inlet, and an air outlet. Both the first air inlet and the air outlet are connected to the first heat exchange chamber. The first heat exchange chamber contains a first heat exchanger and a first fan. The first fan drives gas to enter the first heat exchange chamber through the first air inlet, exchange heat with the first heat exchanger, and flow towards the air outlet. The second air inlet is connected to the second heat exchange chamber, which is also connected to the storage chamber via the air outlet. The second heat exchange chamber is isolated from the first heat exchange chamber. The second heat exchange chamber contains a second heat exchanger and a second fan. The second fan drives gas to enter the second heat exchange chamber through the second air inlet, exchange heat with the second heat exchanger, and flow towards the storage chamber. The storage chamber also has an exhaust port configured to connect to an exhaust pipe.

[0005] The beneficial effects of this invention's integrated drying and preservation portable air conditioner are:

[0006] By installing corresponding first fans and first heat exchangers in the first and second heat exchange chambers, respectively, the first heat exchanger can exchange heat with the air flowing in the first heat exchange chamber, discharging hot or cold air to heat or cool the corresponding space. Conversely, a heat exchange process occurs in the second heat exchanger in the opposite direction to generate cold or hot air, which flows through the air outlet into the storage cavity to dry the stored items. The gas is then discharged through the exhaust port and exhaust pipe. This method fully utilizes waste heat or waste cold energy generated during the cooling or heating process, thereby achieving efficient resource utilization and reducing energy consumption.

[0007] In addition, integrating the storage cavity into the housing allows for the integration of drying or preservation functions with the functions of a portable air conditioner, reducing the space occupied and simplifying the complex piping connection process. This not only improves space utilization but also reduces the operational process and minimizes indoor piping, preventing operators from tripping over the pipes.

[0008] In a preferred embodiment, the first heat exchange chamber is located at the upper part of the shell, and the air outlet is located at the top of the first heat exchange chamber.

[0009] By placing the air outlet at the top of the first heat exchange chamber, air can enter through the first air inlet, release heat to the first heat exchanger, and then exhaust cold air from the air outlet. The cold air is blown out from a higher position, which helps to make the cooling in the space more uniform and improves the user experience.

[0010] In a preferred embodiment, the storage cavity is located below the second heat exchange cavity, the air outlet is located at the bottom of the second heat exchange cavity, the second air inlet is located on the side wall of the second heat exchange cavity, and the second air inlet and the first air inlet are located on opposite sides of the housing.

[0011] The storage cavity is positioned below the second heat exchanger, allowing air to enter from above and exit from a lower position. This allows the exhaust pipe to be positioned lower, reducing interference with the layout of other equipment besides the portable air conditioner. Furthermore, the second and first air inlets are located on opposite sides of the casing, drawing air from each side. This ensures each inlet receives sufficient air, improving intake efficiency and preventing insufficient air intake caused by drawing air from only one side.

[0012] In a preferred embodiment, the air outlet is detachably connected to a first filter.

[0013] By detachably connecting the first filter to the air outlet, the air flowing out of the second heat exchange chamber is filtered to prevent impurities from flowing into the storage chamber with the air and contaminating the items stored in the storage chamber.

[0014] In a preferred embodiment, the exhaust port is provided with a second filter.

[0015] Because the gas discharged from the second heat exchange chamber also flows at a relatively high speed, the airflow in the storage chamber is also quite vigorous. The second filter prevents objects from being carried into the exhaust port and exhaust pipe by the air flowing from the storage chamber, thus avoiding blockage. Furthermore, it also prevents items in the storage chamber from falling and blocking the exhaust pipe.

[0016] In a preferred embodiment, the storage cavity is provided with a shelf, which is made of metal.

[0017] When the air conditioner is in cooling mode, the air flowing from the vent into the storage compartment can reach temperatures of 30°C to 60°C. If plastic parts are used, prolonged exposure to this temperature will accelerate the aging of the plastic. Therefore, metal storage racks are preferable as they are less prone to deformation and have a longer lifespan.

[0018] In a preferred embodiment, a first air duct is provided in the first heat exchange chamber. The first air duct has a first bottom wall and a first side wall. The bottom wall and the air outlet are located on opposite sides of the first fan. The first side wall and the first heat exchanger are located on opposite sides of the first fan. The distance between the first side wall and the first air inlet gradually increases from bottom to top. A first water receiving tray is provided below the outer side of the first side wall, below the first heat exchanger, and below the first bottom wall.

[0019] By configuring the first sidewall in this way, it can guide the gas flow entering the first heat exchange chamber from the first air inlet, changing it from a horizontal flow to an upward oblique flow, reducing air loss in the first heat exchange chamber and improving airflow efficiency. Furthermore, by placing the first water collection tray below the outer side of the first sidewall, below the first heat exchanger, and below the first bottom wall, even when the portable air conditioner is cooling, if the air outside the first sidewall condenses upon encountering the cooler sidewall, producing condensation, the condensate will flow downwards along the outer side of the first sidewall and onto the first water collection tray, preventing it from dripping directly and splashing onto other components of the portable air conditioner.

[0020] In a preferred embodiment, the second heat exchange chamber is provided with a second air duct, which includes a second side wall and a second bottom wall. The second side wall and the second air inlet are located on opposite sides of the second fan. A second water receiving tray is provided below the second bottom wall and below the second heat exchanger. The distance between the second side wall and the second air inlet gradually increases from top to bottom.

[0021] By shaping the second sidewall of the second air duct as described above, the second sidewall can guide the gas flow entering the second heat exchange chamber from the second air inlet, changing it from a horizontal flow to a downward or even downward flow, reducing air loss in the second heat exchange chamber and improving airflow efficiency. Furthermore, by placing the second drip tray below the second bottom wall and the second heat exchanger, when the air conditioner is heating, condensation occurs on the second heat exchanger or the outer sidewall. The condensation flows along the outer sidewall to the edge of the second bottom wall and is collected by the second drip tray, preventing condensation from dripping onto items in the storage cavity.

[0022] In a preferred embodiment, the bottom of the storage cavity is provided with a third water receiving tray, the third water receiving tray is provided with a drain hole, the drain hole is used to discharge accumulated water to the bottom of the housing, and the bottom of the housing is provided with a drain pipe.

[0023] By setting a third water receiving tray with a drain hole, water dripping from the upper water receiving tray or stored items can be collected and drained into the drain hole of the third water receiving tray, draining into a designated area at the bottom of the housing. This prevents large-scale dripping and splashing water from causing related electrical components to malfunction.

[0024] In a preferred embodiment, the integrated drying and preservation portable air conditioner further includes a compressor and an electrical control box. The compressor and the electrical control box are installed at the bottom of the housing. The compressor, together with the first heat exchanger and the second heat exchanger, form a refrigerant circuit.

[0025] Placing heavier components like the compressor and control box at the bottom of the casing lowers the center of gravity of the portable air conditioner, improving overall stability and saving space. Attached Figure Description

Detailed Implementation

[0039] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] Example 1:

[0041] Figure 1 This is a front view of the integrated drying and preservation portable air conditioner provided in an embodiment of the present invention, with the door closed at this time. Figure 4 This is a front view of the integrated drying and preservation portable air conditioner provided in an embodiment of the present invention, with the door in the open position. Figure 8 This is a front view of the internal structure of the integrated drying and preservation portable air conditioner provided in an embodiment of the present invention. Figure 9 This is a right view of the internal structure of a portable air conditioner integrating drying and preservation provided in an embodiment of the present invention. Figure 1, Figure 4 and Figure 8 , Figure 9 As shown, the portable air conditioner with integrated drying and preservation provided in this embodiment includes a housing 10. The housing 10 contains a first heat exchange chamber 20, a second heat exchange chamber 30, and a storage chamber 40. The housing 10 has a first air inlet 21, a second air inlet 31, and an air outlet 22. Both the first air inlet 21 and the air outlet 22 are connected to the first heat exchange chamber 20. The first heat exchange chamber 20 contains a first heat exchanger 24 and a first fan 25. The first fan 25 drives gas to enter the first heat exchange chamber 20 from the first air inlet 21 and exchange gases with the first heat exchanger 24. The gas flows into the outlet 22; the second inlet 31 is connected to the second heat exchange chamber 30, and the second heat exchange chamber 30 is also connected to the storage chamber 40 through the outlet 32. The second heat exchange chamber 30 is isolated from the first heat exchange chamber 20. The second heat exchange chamber 30 is provided with a second heat exchanger 34 and a second fan 35. The second fan 35 is used to drive the gas to enter the second heat exchange chamber 30 from the second inlet 31, exchange heat with the second heat exchanger 34, and flow into the storage chamber 40. The storage chamber 40 is also provided with an exhaust port 41, which is configured to be connected to the exhaust pipe 42.

[0042] The storage cavity 40 is also movably connected to a switch door 46. When the switch door 46 is open, items can be taken out of or placed into the storage cavity 40. When the integrated drying and preservation portable air conditioner is running, it is best to close the switch door 46 to minimize direct heat exchange between the storage cavity 40 and the outside environment. In addition, casters 99 are provided on the bottom surface of the housing 10 to facilitate the movement of the integrated drying and preservation portable air conditioner.

[0043] By respectively installing a first fan 25, a first heat exchanger 24, a second fan 35, and a second heat exchanger 34 in the first heat exchange chamber 20 and the second heat exchange chamber 30, the first heat exchanger 24 can exchange heat with the air flowing in the first heat exchange chamber 20, discharging hot or cold air to heat or cool the corresponding space. Correspondingly, a heat exchange process in the opposite direction occurs in the second heat exchanger 34 to generate cold or hot air, which flows through the air outlet 32 ​​into the storage chamber 40 to dry the stored items in the storage chamber 40, and the gas is discharged through the exhaust port 41 and exhaust pipe 42. This fully utilizes the waste heat or waste cold energy generated during the cooling or heating process of the space, thereby achieving efficient resource utilization and reducing energy consumption.

[0044] In addition, integrating the storage cavity 40 into the housing 10 can realize the integration of drying or preservation functions with the functions of a portable air conditioner, reducing the occupancy of indoor space and the complex piping connection process. This not only improves space utilization but also reduces the operation process. At the same time, it can also reduce indoor piping and prevent operators from tripping over the pipes.

[0045] Figure 2 for Figure 1 The right view of the portable air conditioner that combines drying and preservation. Figure 3 for Figure 1 The top view of the portable air conditioner that combines drying and preservation is shown. Figure 5 for Figure 4 The right view of the portable air conditioner that combines drying and preservation. Figure 6 for Figure 4 The top view of the portable air conditioner that combines drying and preservation is shown. Figure 7 for Figure 4 The rear view of the portable air conditioner with integrated drying and preservation functions is shown; as shown. Figures 1-7 As shown, preferably, the first heat exchange chamber 20 is located at the upper part of the shell 10, and the air outlet 22 is located at the top of the first heat exchange chamber 20.

[0046] In this design, the side of the storage compartment 40 of the portable air conditioner where items can be placed or removed is defined as the front side, and the front, back, left, and right sides are defined accordingly. The air outlet 22 is located at the top of the first heat exchange chamber 20, i.e., the top of the housing 10. However, the air outlet 22 does not simply expel air upwards; it has a guide damper 23 that can rotate along a horizontal axis, opening or closing. Therefore, the air outlet 22 expels air in a forward and upward direction. The first air inlet 21 is located at the rear of the first heat exchange chamber 20. Furthermore, the first heat exchanger 24 is positioned within the first heat exchange chamber 20, adjacent to the first air inlet 21, allowing the incoming air to flow through the first heat exchanger 24 with a larger flow cross-section, resulting in more thorough heat exchange and improved heat exchange efficiency.

[0047] By placing the air outlet 22 at the top of the first heat exchange chamber 20, air can enter from the first air inlet 21, release heat to the first heat exchanger 24, and then exhaust cold air from the air outlet 22. The cold air blown out from a higher position is conducive to more uniform cooling in the space and improves the user experience.

[0048] like Figure 4 and Figure 8 , Figure 9 As shown, preferably, the storage cavity 40 is located below the second heat exchange cavity 30, the air outlet 32 ​​is located at the bottom of the second heat exchange cavity 30, the second air inlet 31 is located on the side wall of the second heat exchange cavity 30, and the second air inlet 31 and the first air inlet 21 are located on opposite sides of the housing 10 respectively.

[0049] Specifically, the second air inlet 31 is located on the front side of the housing 10, and the first air inlet 21 is located on the rear side of the housing 10. This arrangement facilitates airflow into the first heat exchange chamber 20 from the rear and outwards from the top, thus improving airflow smoothness within the first heat exchange chamber 20. In the second heat exchange chamber 30, the second heat exchanger 34 is positioned immediately adjacent to the second air inlet 31, allowing the incoming air to flow through the second heat exchanger 34 with a larger flow cross-section, resulting in more thorough heat exchange and improved heat exchange efficiency.

[0050] The placement of the storage cavity 40 below the second heat exchanger 34 allows air to enter the storage cavity 40 from above and exit from a lower position. This allows the exhaust pipe 42 to be positioned lower, reducing interference with the layout of other equipment besides the portable air conditioner. Furthermore, the second air inlet 31 and the first air inlet 21 are located on opposite sides of the housing 10, drawing air from opposite sides of the housing 10. Each air inlet receives a sufficient amount of air, improving intake efficiency and preventing insufficient air intake caused by drawing air from only one side.

[0051] Figure 10 This is a schematic diagram of the integrated drying and preservation portable air conditioner provided in an embodiment of the present invention, viewed from above the storage compartment. Figures 8-10 As shown, preferably, the air outlet 32 ​​is detachably connected to a first filter 33.

[0052] Specifically, the first filter 33 can be set on the lower surface of the air outlet 32, that is, the upper surface of the storage cavity 40.

[0053] By detachably connecting the first filter 33 to the air outlet 32, the first filter 33 is used to filter the air flowing out of the second heat exchange chamber 30, preventing impurities from flowing into the storage chamber 40 with the air and contaminating the items stored in the storage chamber 40.

[0054] like Figure 4 and Figure 8 , Figure 9 As shown, preferably, the exhaust port 41 is provided with a second filter 43.

[0055] Specifically, the second filter 43 is disposed on the inner side of the exhaust port 41. The pore size of the second filter 43 is larger than that of the first filter 33.

[0056] Since the gas discharged from the second heat exchange chamber 30 has a relatively high flow rate, the airflow in the storage chamber 40 is also quite vigorous. The second filter 43 prevents objects from being carried into the exhaust port 41 and exhaust pipe 42 by the air flowing from the storage chamber 40 to the exhaust pipe 42, thus preventing blockage of the exhaust pipe 42. Furthermore, it also prevents items in the storage chamber 40 from falling and blocking the exhaust pipe 42.

[0057] like Figure 4 and Figure 8 , Figure 9 As shown, preferably, the storage cavity 40 is provided with a storage rack 44, which is made of metal.

[0058] When the air conditioner is in cooling mode, the air flowing from the air outlet 32 ​​to the storage compartment 40 may reach temperatures of 30°C to 60°C. If plastic parts are used, prolonged exposure to this temperature will accelerate the aging of the plastic. Therefore, a metal storage rack 44 is chosen because it is less prone to deformation and has a longer service life.

[0059] like Figure 8 and Figure 9 As shown, preferably, a first air duct 26 is provided in the first heat exchange chamber 20. The first air duct 26 has a first bottom wall 28 and a first side wall 27. The bottom wall and the air outlet 22 are located on opposite sides of the first fan 25. The first side wall 27 and the first heat exchanger 24 are located on opposite sides of the first fan 25. The distance between the first side wall 27 and the first air inlet 21 gradually increases from bottom to top. A first water receiving tray 29 is provided on the lower side of the outer side of the first side wall 27, the lower side of the first heat exchanger 24, and the lower side of the first bottom wall 28.

[0060] More specifically, the first sidewall 27 can be arc-shaped, with a small angle between the bottom of the arc and the horizontal plane, and a large angle between the top of the arc and the horizontal plane. The angle of the inner surface of the first sidewall 27 gradually increases from bottom to top.

[0061] By configuring the first sidewall 27 in this way, it can guide the gas flow entering the first heat exchange chamber 20 from the first air inlet 21, changing it from a horizontal flow to an upward flow, reducing air loss in the first heat exchange chamber 20 and improving airflow efficiency. Furthermore, by placing the first water tray 29 below the outer side of the first sidewall 27, below the first heat exchanger 24, and below the first bottom wall 28, even when the portable air conditioner is cooling, if the air outside the first sidewall 27 condenses upon encountering the cooler sidewall 27, producing condensation, it will flow downwards along the outer side of the first sidewall 27 and onto the first water tray 29, preventing it from dripping directly and splashing onto other components of the portable air conditioner.

[0062] like Figure 8 and Figure 9As shown, preferably, the second heat exchange chamber 30 is provided with a second air duct 36, which includes a second side wall 37 and a second bottom wall 38. The second side wall 37 and the second air inlet 31 are located on opposite sides of the second fan 35. The distance between the second side wall 37 and the second air inlet 31 gradually increases from top to bottom. A second water receiving tray 39 is provided below the second bottom wall 38 and below the second heat exchanger 34.

[0063] Specifically, the second sidewall can be arc-shaped, with a small angle between the top of the arc and the horizontal plane, and a large angle between the bottom of the arc and the horizontal plane. The angle of the inner surface of the second sidewall 37 gradually increases from top to bottom.

[0064] By configuring the second sidewall 37 of the second air duct 36 into the aforementioned shape, the second sidewall 37 can guide the gas flow entering the second heat exchange chamber 30 from the second air inlet 31, changing it from a horizontal flow to a downward or even downward flow, reducing air loss in the second heat exchange chamber 30 and improving airflow efficiency. Furthermore, by positioning the second water tray 39 below the second bottom wall 38 and below the second heat exchanger 34, when the air conditioner is heating, condensation occurs on the second heat exchanger 34 or the outer sidewall 37. The condensation flows along the outer sidewall 37 to the edge of the second bottom wall 38 and is collected by the second water tray 39, preventing condensation from dripping onto items in the storage cavity 40.

[0065] like Figure 8 and Figure 9 As shown, preferably, the bottom of the storage cavity 40 is provided with a third water receiving tray 45, the third water receiving tray 45 is provided with a drain hole, the drain hole is used to discharge accumulated water to the bottom of the housing 10, and the bottom of the housing 10 is provided with a drain pipe 53.

[0066] The third water tray 45 covers the entire bottom area of ​​the storage cavity 40. The third water tray 45 is also lower than the vent 41 of the storage cavity 40.

[0067] By setting a third water receiving tray 45 and a drain hole on the third water receiving tray 45, the water dripping from the water receiving tray above it or from the stored items can be collected and gathered into the drain hole of the third water receiving tray 45, draining into the designated area at the bottom of the housing 10 and flowing out from the drain pipe 53, avoiding large-scale dripping and preventing water splashing that could cause related electrical components to fail.

[0068] like Figure 8 As shown, preferably, the integrated drying and preservation portable air conditioner also includes a compressor 51 and an electrical control box 52. The compressor 51 and the electrical control box 52 are installed at the bottom inside the housing 10. The compressor 51, together with the first heat exchanger 24 and the second heat exchanger 34, form a refrigerant circuit.

[0069] By placing heavier components such as the compressor 51 and the electrical control box 52 at the bottom of the housing 10, the center of gravity of the portable air conditioner can be lowered, improving the stability of the entire unit and saving space.

[0070] The operating principle of this embodiment is as follows:

[0071] When the portable air conditioner with drying and preservation functions is needed to cool the room, the first fan 25 starts, drawing air into the first heat exchange chamber 20 through the first air inlet 21. This air releases heat to the first heat exchanger 24, becoming cooler air, which is then discharged from the air outlet 22 through the air guide damper 23, thus cooling the room. Simultaneously, the second fan 35 also starts, drawing air into the second heat exchange chamber 30 through the second air inlet 31. This air absorbs heat from the second heat exchanger 34, becoming warmer air, which is then discharged from the air outlet 32 ​​and enters the storage chamber 40. If the storage chamber 40 contains items such as bowls and chopsticks, the hot air can be used to dry them. Meanwhile, the compressor 51 operates, compressing, heating, and pressurizing the refrigerant, driving it to flow into the second heat exchanger 34 and releasing heat to the air in the second heat exchange chamber 30. Then, the refrigerant flows into the first heat exchanger 24, absorbing heat from the air in the first heat exchange chamber 20, thus cooling that part of the air. Then, the refrigerant flows back from the first heat exchanger 24 to the compressor 51, continuing the cycle.

[0072] When the portable air conditioner with drying and preservation functions is needed to heat the room, the first fan 25 starts, drawing air into the first heat exchange chamber 20 through the first air inlet 21. This air absorbs heat from the first heat exchanger 24, becoming warmer air, which is then discharged from the air outlet 22 through the air guide damper 23, thus heating the room. Simultaneously, the second fan 35 also starts, drawing air into the second heat exchange chamber 30 through the second air inlet 31. This air releases heat to the second heat exchanger 34, becoming cooler air, which is then discharged from the air outlet 32 ​​and enters the storage chamber 40. If the storage chamber 40 contains items, such as food, the cool air can be used to preserve them. Meanwhile, the compressor 51 operates, compressing, heating, and pressurizing the refrigerant, driving it to flow into the first heat exchanger 24 and release heat to the air in the first heat exchange chamber 20. Then, the refrigerant flows into the second heat exchanger 34, absorbing heat from the air in the second heat exchange chamber 30, thus cooling this part of the air. Then, the refrigerant flows back from the second heat exchanger 34 to the compressor 51, continuing the cycle.
