Abstract
Description
Technical Field
[0001] The utility model relates to the field of air conditioning technology, specifically to a split-type portable air conditioner that utilizes condensate water for cooling. Background Technology
[0002] Split-type portable air conditioners consist of an indoor unit and an outdoor unit. In cooling mode, the condensate from the indoor unit is drained into the outdoor unit's drip tray within a short time. Condensate exceeding the drip tray's capacity is naturally drained into the outdoor space through the overflow outlet. During this process, the condensate is consumed in the condenser's heat exchange. The indoor unit needs to store water for a certain period before resupplying. Furthermore, the humidity in the indoor space is variable; the longer the cooling operation time, the lower the indoor humidity. Therefore, there is a possibility that the outdoor unit's condensate may be depleted before the indoor unit's condensate is supplied to the outdoor unit, leading to unstable overall performance.

[0015] This utility model discloses a split-type portable air conditioner that uses condensate water for cooling, including an indoor unit and an outdoor unit. A water tank is added inside the outdoor unit to store excess condensate water for later use. This solves the problem that in cooling mode, when the indoor humidity is high at the beginning and the amount of condensate water is large, after a period of time, when the indoor humidity decreases and the amount of condensate water decreases, the water volume in the second drip tray cannot keep up, which affects the cooling effect of the condenser and thus affects the cooling effect.

[0025] Please see Figure 1The present invention provides a split-type portable air conditioner that utilizes condensate water for cooling. The split-type portable air conditioner includes an indoor unit 1 and an outdoor unit 2. The indoor unit 1 is installed indoors, and the outdoor unit 2 is installed outdoors. The indoor unit 1 includes a cross-flow fan 12 located at the center of its interior, and an evaporator 11 located above the cross-flow fan 12. A foam duct 13 is located below the cross-flow fan 12, which restricts the airflow from the cross-flow fan 12 to move along a preset path. A first drip tray 17 is located at the lowest end of the evaporator 11. In the cooling mode of the split-type portable air conditioner, a large number of liquid droplets condense on the evaporator 11, and the first drip tray 17 can collect the liquid droplets falling along the evaporator 11. The indoor unit 1 is also equipped with a water storage box 16 at the bottom. The water storage box 16 is used to store the condensate collected in the first water tray 17. The water storage box 16 is equipped with a water pump 15, which is connected to the drain pipe 19. The water pump 15 can transport the condensate stored in the water storage box 16 out through the drain pipe 19. The outdoor unit 2 includes a condenser 21 located on one side inside the outdoor unit 2 and a water tank 22 located at the bottom of the outdoor unit 2. The condenser 21 is equipped with a second water tray 23 below it. The second water tray 23 is used to receive the cooling water flowing down the condenser 21. The water tank 22 has an inlet 221 on the side near the indoor unit 1 and an outlet 222 on the side near the condenser 21. The drain pipe 19 is connected to the water tank 22 through the inlet 221. The water in the water tank 22 can flow into the second water tray 23 through the outlet 222.
[0026] In some embodiments, the evaporator 11 is a three-section evaporator, which is inverted in a U-shape on the cross-flow impeller 12. Each end of the evaporator 11 (the ends of the first and third sections) is provided with a first water receiving tray 17. The condensate collected in the first water receiving tray 17 can flow into the water storage box 16. The water storage box 16 is also provided with a first water level switch 18 for monitoring the liquid level in the water storage box 16. The first water level switch 18 is electrically connected to the water pump 15. When the water level in the water storage box 16 is higher than the preset liquid level of the first water level switch 18, the first water level switch 18 can control the water pump 15 to start and transport the condensate in the water storage box 16 to the water tank 22 through the drain pipe 19. When the water level in the water storage box 16 is lower than the preset liquid level of the first water level switch 18, the first water level switch 18 can control the water pump 15 to shut down and stop the condensate from being transported to the water tank 22 through the drain pipe 19. A first electrical control box 14 is also located at the bottom of the indoor unit 1, away from the water storage box 16. This box provides power to the electrical components inside the indoor unit 1 and provides an installation location for the controllers of these components. The indoor unit 1 and outdoor unit 2 can be installed in various scenarios, potentially with height differences. Especially when the indoor unit 1 is installed at a lower position than the outdoor unit 2, a water pump 15 can be installed to drain the condensate from the indoor unit's water storage box 16 into the water tank 22.
[0027] In some embodiments, a water pumping motor 27 is provided in the second water receiving tray 23. The water pumping motor 27 can atomize the water in the second water receiving tray 23 into a water mist and disperse it on the surface of the condenser 21. The water pumping motor 27 is provided with a third water level switch 271 to monitor the liquid level in the second water receiving tray 23. The water tank 22 is provided with an electric valve 26 at the outlet 222. The electric valve 26 and the third water level switch 271 are electrically connected. When the third water level switch 271 detects that the liquid level in the second water receiving tray 23 is lower than the preset water level, the third water level switch 271 controls the electric valve 26 to open, and the condensate in the water tank 22 flows into the second water receiving tray 23 below under the action of gravity. When the third water level switch 271 detects that the liquid level in the second water receiving tray 23 is higher than the preset water level, the third water level switch 271 controls the electric valve 26 to close, and stops replenishing condensate into the second water receiving tray 23.
[0028] In some embodiments, a second water level switch 25 is installed at the upper end of the water tank 22 near the second water receiving tray 23. The second water level switch 25 is electrically connected to the electric valve 26. The second water receiving tray 23 is provided with an overflow port 231. When the liquid level in the water tank 22 is higher than the upper limit of the preset water level of the second water level switch 25, the second water level switch 25 can control the electric valve 26 to open and discharge a portion of the condensate in the water tank 22. At this time, if the liquid level in the second water receiving tray 23 is full, the condensate in the second water receiving tray 23 can overflow from the overflow port 231 and be discharged outdoors. When the liquid level in the water tank 22 drops to the lower limit of the preset water level of the second water level switch 25, the second water level switch 25 controls the electric valve 26 to close. This can prevent the condensate in the water tank 22 from being too full, which would affect the water pump 15 from discharging the condensate collected in the water storage box 16 and cause the risk of condensate overflowing from the indoor unit's water storage box 16 into the room. The outdoor unit 2 also has a second electrical control box 24 inside, which is used to provide power to the electrical components inside the outdoor unit 2 and to provide an installation position for the controller of the electrical components.
[0029] In some embodiments, the drainage pipe 19 is a flexible pipe, preferably made of EPDM rubber or silicone with excellent aging resistance.
[0030] When the split-type portable air conditioner using condensate cooling provided by this utility model is operating in cooling mode, the condensate condensed on the evaporator 11 of the indoor unit 1 collects in the first drip tray 17 and is stored in the water storage box 16 through pipes. When the condensate level in the water storage box 16 reaches the upper limit preset by the first water level switch 18, the first water level switch 18 electrically controls the water pump 15 to start, transporting the condensate in the water pump 15 to the water tank 22. When the condensate level in the water storage box 16 falls below the lower limit preset by the first water level switch 18, the first water level switch 18 controls the water pump 15 to shut off to prevent the water pump 15 from running dry and affecting cooling. The lifespan of the water pump 15 is as follows: The third water level switch 271 on the water pump motor 27 can monitor the liquid level of the water pump motor 27. When the liquid level of the water pump motor 27 is lower than the preset lower limit of the water level of the third water level switch 271, the third water level switch 271 controls the electric valve 26 to open, replenishing condensate into the second water receiving pan 23. When the liquid level of the water pump motor 27 is higher than the preset upper limit of the water level of the third water level switch 271, the third water level switch 271 controls the electric valve 26 to close, preventing excessive water overflow in the second water receiving pan 23, which would be wasteful, or causing insufficient condensate supply when the indoor humidity decreases and the amount of condensate decreases. The water pump motor 27 atomizes the condensate in the second water receiving pan 23 into a water mist that comes into contact with the condenser 21, carrying away the heat from the high-temperature condenser 21 and increasing the cooling effect of the split-type portable air conditioner.
[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
