In one embodiment, as shown in fig. 2, the control method includes:

s1, judging whether the dish-washing machine enters a drying stage. In particular, the dishwasher may enter a drying phase after the end of a washing phase, and may stop the water supply into the tub at the end of the washing phase.

And S2, if so, opening the first air inlet and the dehumidification and refrigeration system. Specifically, when the dish washer enters a drying stage, the dehumidification and refrigeration system works, the first air inlet is opened, the second air outlet is communicated with the first air inlet, the dehumidification and refrigeration system enters outside humid air, moisture in the air is condensed into condensed water, the moisture in the air enters the inner container through the second air outlet and the first air inlet after being removed, tableware in the inner container and the inner container is dried, and the air after drying is discharged through the first air outlet. Therefore, the control method of the dishwasher can dry the air in the drying stage, and improve the drying efficiency.

and S3, acquiring the current humidity in the inner container. Specifically, a first humidity sensor may be installed in the inner container, and the current humidity in the inner container may be detected by the first humidity sensor.

And S4, judging whether the current humidity is lower than the set humidity. Specifically, when the current humidity is lower than the set humidity, it indicates that the humidity in the liner is low, and the drying operation may be ended, and when the current humidity is higher than the set humidity, it indicates that the drying operation is to be continued.

And S5, if yes, controlling the first air inlet to be closed. Specifically, when the current humidity is lower than the set humidity, it is indicated that the humidity in the inner container is low, and at this time, the first air inlet can be controlled to be closed to stop the drying operation.

Specifically, the dehumidification refrigeration system can be provided with a second air outlet and a third air outlet, the second air outlet is communicated with the first air inlet, the third air outlet is communicated with the outside, a switch element can be set to open or close the third air outlet, when the drying stage is finished, the third air outlet can be opened, and the dehumidified air is blown out through the third air outlet.

and S6, acquiring the environment humidity. Specifically, a second humidity sensor may be disposed at a second air inlet of the dehumidification and refrigeration system, or a second humidity sensor may be disposed outside the dishwasher, and the ambient humidity is obtained through the second humidity sensor.

And S7, judging whether the environment humidity is larger than a preset humidity or not. Specifically, the preset humidity may be 50%, or may be set to 40% or 60% as the case may be.

And S8, if so, starting the dehumidification refrigeration system. Specifically, when the ambient humidity is greater than the preset humidity, the ambient humidity is relatively high, the moisture content in the air is relatively high, the dehumidification refrigeration system is started at the moment, the water in the air is separated to form condensed water, and the condensed water can be used for washing. And when the environment humidity is less than or equal to the preset humidity, the dehumidification refrigeration system does not need to be started.

In this embodiment, after S8, the method further includes:

s9, judging whether the water inlet valve is opened or not. In particular, the water inlet valve is automatically controlled to open when the dishwasher enters a washing phase, and thus, when the water inlet valve is open, the dishwasher enters a washing phase.

And S10, if yes, starting the sterilization structure. Specifically, the sterilization structure is an ultraviolet lamp, when the dishwasher enters a washing stage, the ultraviolet lamp can be turned on to sterilize and disinfect water before the water enters the inner container, so that the water quality of the water entering the inner container is ensured, and the health of a user is further ensured.

In the washing stage, when the water amount entering the inner container is enough, the water inlet needs to be stopped, and specifically, after the step S10, the method further includes:

s11, judging whether the water quantity entering the inner container meets a set value or not. Specifically, the amount of water entering the inner container can be counted by a flow meter on the pipeline structure.

S12, if yes, closing the water inlet valve and the sterilization structure. Specifically, when the water amount entering the inner container meets a set value, the washing work can be started, water does not need to be continuously fed, the water inlet valve is closed, the sterilization structure is closed, and electric energy can be saved.

In this embodiment, the condensed water produced by the dehumidification refrigeration system can be stored in the water tank after being filtered by the filtering structure, and when washing, the condensed water stored in the water tank flows into the inner container through the pipeline structure, so as to meet the requirement of rapid water intake during washing, and in order to avoid the overflow of water in the water tank, the control method further comprises:

s13, judging whether the water level in the water tank exceeds a preset water level or not. Specifically, a water level sensor may be installed in the water tank, and the water level in the water tank is detected by the water level sensor.
