If more water leakage holes are arranged, when the amount of condensed water is less, the support strength of the middle partition plate 2 is insufficient due to the fact that more water leakage holes are formed in the middle partition plate 2, the service life of the middle partition plate 2 is affected, and then the normal operation of the mobile air conditioner is affected. The invention sets the water falling holes with different height of the weir, so that the middle baffle plate 2 has the function of selectively draining water, not only can meet the drainage requirement, but also can not cause the problems of insufficient strength of the middle baffle plate 2 or other increased process difficulty and complexity.
Further, in order to better buffer the accumulated water pressure on the middle partition plate 2, a corresponding warning device is arranged in the third area, when the water level of the condensed water on the middle partition plate 2 continuously rises to enable the condensed water to start to be discharged from the three water falling holes 27, the warning device is started, so that the attention of a user is drawn, the situation that more condensed water is accumulated on the middle partition plate 2 and needs to be timely discharged is described, a drain pipe is connected with the drain nozzle 24, the condensed water is discharged from the drain nozzle 24, and when the water level is lower than the height of the third weir on the three water falling holes 27, the warning device is closed.
