Detailed Description

It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict in structure or function. The present invention will be described in detail below with reference to examples.

The utility model discloses a portable air conditioner (hereinafter referred to as air conditioner), as shown in fig. 1 to 14, including bottom plate 142 and with bottom plate 142 fixed connection's shell, with form inside installation cavity, with the part of installation air conditioner, wherein in the installation cavity, be provided with evaporation heat exchanger 109 in bottom plate 142 front side, be provided with condensation heat exchanger 106 in bottom plate 142 rear side, still include water collector 162, this water collector 162 has the first water receiving section 1621 that sets up under evaporation heat exchanger 109, this water collector 162 inclines the setting in the past backward, this water collector 162 is located more than bottom plate 142, and there is the interval between the bottom plate 142. Wherein, the periphery of the water pan 162 is a vertical wall surface, so as to form a cavity for containing water, so that the water pan 162 is arranged, and the first water receiving section 1621 of the water pan 162 is arranged below the evaporation heat exchanger 109, thereby collecting the condensed water generated by the evaporation heat exchanger 109 when the air conditioner is refrigerating, preventing the condensed water from directly flowing onto the bottom plate 142, and a certain distance exists between the water pan 162 and the bottom plate 142, as shown in fig. 14, if the distance is arranged between 0.5cm and 5cm, so that an air space exists between the water pan 162 and the bottom plate 142, thereby preventing the low temperature of the condensed water on the water pan 162 from being transferred onto the bottom plate 142, thereby preventing the bottom plate 142 from generating condensation phenomenon due to temperature reduction, even if the condensation is generated on the outer surface of the water pan 162, the water amount of small water drops generated by the condensation is much less, even if the water drops onto the bottom plate 142, the very small amount of water can be evaporated by the bottom plate 142 with relatively high temperature, without a substantial decrease in the temperature of the bottom plate 142. And the water pan 162 is arranged to incline from the front side of the evaporation heat exchanger 109 to the rear side of the condensation heat exchanger 106, so that condensed water dropping from the evaporation heat exchanger 109 can be quickly drained away by the water pan 162, and can not be accumulated at the position of the first water receiving section 1621 to cause an overflow phenomenon.

In some embodiments of the present invention, the water receiving tray 162 further includes a second water receiving section 1622, which is a narrow plate and disposed under the refrigerant pipeline, and the refrigerant pipeline is the refrigerant pipe connection section 164 shown in fig. 3 for connecting the air suction pipe of the compressor 107 to the evaporation heat exchanger 109. According to the working principle of the air conditioner, the high-temperature and high-pressure gaseous refrigerant in the refrigerant pipe from the exhaust port of the compressor 107 passes through the condensing heat exchanger 106 to discharge heat outwards to cool the refrigerant in the refrigerant pipeline, then becomes low-temperature and high-pressure liquid refrigerant, passes through the throttling and pressure reducing component such as the capillary tube 163 to be throttled and reduced in pressure to become low-temperature and high-pressure liquid refrigerant with low temperature, then enters the evaporating heat exchanger 109, absorbs heat to the surrounding environment through the evaporating heat exchanger 109 to reduce the temperature of the refrigerant, the temperature of the refrigerant rises, the temperature in the refrigerant pipe penetrating through the evaporating heat exchanger 109 is very low, the temperature of the fins of the evaporating heat exchanger 109 installed on the refrigerant pipe is also very low, therefore, condensed water is generated and drops to the first water receiving section 1621 of the water receiving tray 162 below the evaporating heat exchanger 109, and then becomes low-temperature gaseous refrigerant after coming out of the evaporating heat exchanger 109, finally enters the suction port of, and the process is circulated. Therefore, the refrigerant pipe connecting the inlet and the outlet of the evaporating heat exchanger 109 absorbs heat to the outside, so that the temperature of the refrigerant pipe is low, generally lower than 2 °, and therefore condensed water is easily generated in the refrigerant pipe, particularly, the refrigerant pipe connecting section 164, which is the refrigerant pipe connecting the suction port of the compressor 107, and the refrigerant pipe connecting the evaporating heat exchanger 109 and the condensing heat exchanger 106, is mainly a capillary tube 163, and the pipe diameter thereof is much smaller than that of the refrigerant pipe at other positions, so that much less condensed water is generated and the condensed water is not easily dropped. Therefore, it is preferable to dispose the refrigerant pipe connecting section 164, which is a refrigerant pipe connected to the suction port of the compressor 107, above the water receiving tray 162, i.e., above the second water receiving section 1622, so as to receive the dropped condensed water.
