as described in the background art, the conventional excavator air conditioner is designed to retain a lot of condensed water on an air conditioning core inside an air conditioning box after being refrigerated in summer for a period of time, a part of the condensed water is converged into water flow and is discharged out of the air conditioning box through a drain pipe, but still a lot of condensed water is attached to the air conditioning core, if the excavator air conditioner is not started within a few days, a large amount of bacteria can be bred in the air conditioning box by the residual condensed water, and meanwhile, peculiar smell is generated.
Example 1
In a typical embodiment of the present application, a portion of the condensed water is drained out of the air-conditioning case through a drain pipe installed at a lower portion of the air-conditioning case in the related art. The water attached to the cold air core cannot be thoroughly discharged out of the air conditioning box; in order to solve the problem, as shown in fig. 1, the invention provides a method for improving the indoor comfort of the excavator, wherein a negative ion generator 2 is added in an air-conditioning duct of the excavator to optimize the air environment in a cab; the humidity sensor 4 is installed near the air conditioning core body 5, when the excavator stops working, the air conditioning controller automatically opens the warm air duct and the air conditioning external circulation air door after receiving an instruction of closing the air conditioner, water is evaporated by utilizing the high temperature of the environment and the high temperature of the air conditioning box warm air core body 6, the fan of the air conditioner operates, the evaporated water is discharged out of the air conditioning box, and when the result detected by the humidity sensor meets the drying index, the air conditioning system is automatically and completely closed. A part of the condensed water is discharged out of the air-conditioning case through a drain pipe installed at a lower portion of the air-conditioning case. The water attached to the cold air core cannot be thoroughly discharged out of the air conditioning box;
