In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the invention provides a residual water removing system of a dish washing machine, as shown in fig. 1, the residual water removing system of the dish washing machine comprises a water cup 11, a heating mechanism 12 and a controller 13, wherein the water cup 11 is a water cup in the existing dish washing machine, the heating mechanism 12 is arranged at the bottom of the water cup 11, the controller 13 is electrically connected with the heating mechanism 12, and the controller 13 is arranged on the dish washing machine. The controller 13 can obtain a signal indicating the end of the draining process of the dishwasher, that is, when the washing of the dishwasher is finished, the controller 13 obtains the signal indicating the end and controls the heating mechanism 12 to start the heating function under a predetermined condition, for example, after the draining process of the dishwasher is finished, or when the water level at the bottom of the water cup 11 reaches a preset water level, the heat generated by the heating mechanism 12 can evaporate the residual water at the bottom of the water cup. Through this structural design and programming for the inside cleanliness factor of dish washer is kept to the timely evaporation to dryness of residual water in 11 bottoms of dish washer drinking cups, avoids producing the peculiar smell, has solved current dish washer and has had the problem that residual water exists in the washing end with water discharge back bottom.
In a preferred embodiment, the controller 13 of the residual water removing system of the dishwasher according to the embodiment of the present invention is further configured to: after the heating mechanism 12 is controlled to operate at the first preset power for the first preset time, the heating mechanism 12 is controlled to operate at the second preset power for the second preset time, wherein the second preset power is smaller than the first preset power, and when the time that the bottom temperature of the water cup 11 reaches the preset value is smaller than the preset time, the heating mechanism 12 stops operating. Specifically, in order to avoid the temperature of the water cup 11 from rising too high when the controller 13 controls the operation of the heating mechanism 12, as shown in fig. 2, after the controller 13 first controls the heating mechanism 12 to operate at a higher power P1 for a period of time t1, a small amount of water remains at the bottom of the water cup 11, and the water content on the remaining small amount of food residues also decreases, then the controller 13 controls the heating mechanism 12 to operate at a lower power P2 for a period of time t2, and then stops the operation of the heating mechanism 12, during which the water content on the bottom of the water cup 11 and the food residues continues to evaporate, and then the remaining temperature at the bottom of the water cup 11 after the operation of the heating mechanism 12 gradually decreases also evaporates a part of water content, so that when the temperature at the bottom of the water cup 11 decreases to normal temperature, the water content on the bottom of the water cup 11 and the food residues is evaporated to dryness, and the dishwasher, and also ensures that the interior of the dishwasher does not generate peculiar smell due to the residual water.

Specifically, as shown in fig. 3, when the controller 13 controls the heating mechanism 12 to operate, the controller 13 first controls the heating mechanism 12 to operate at a certain power for a period of time, the controller 13 obtains the bottom temperature of the water cup 11 in real time, when the bottom temperature of the water cup 11 reaches a preset temperature T1, in order to avoid overheating of the bottom of the water cup 11 caused by the continuous operation of the heating mechanism 12 at the power, from this moment (assuming a moment T3), the controller 13 controls the heating mechanism 12 to gradually reduce the operating power of the heating mechanism 12 along with the rise of the bottom temperature of the water cup 11, when the moisture at the bottom of the water cup 11 evaporates to dryness, the bottom temperature of the water cup 11 will rise rapidly, the controller 13 indicates that the moisture at the bottom of the water cup 11 has evaporated to dryness when the bottom temperature of the water cup 11 reaches the preset value from the moment T3 and the time is shorter than the preset time (because when there is no residual water at the bottom of the water in the water cup 11, the bottom temperature of, at this time, the operation of the heating means 12 is stopped, i.e., the operating power of the heating means 12 is reduced to 0.
In a preferred embodiment, the controller 13 controls the operation of the heating mechanism 12 by: the controller 13 controls the heating mechanism 12 to operate at a fourth predetermined power for a third predetermined time, stops the heating mechanism 12 when the bottom temperature of the water cup 11 rises to the second predetermined temperature, and controls the heating mechanism 12 to operate at a fifth predetermined power for the fourth predetermined time when the bottom temperature of the water cup 11 decreases to the third predetermined temperature, and stops the heating mechanism 12 from operating until the time when the bottom temperature of the water cup 11 reaches the predetermined value is less than the predetermined time. The third preset time and the fourth preset time may be equal or unequal, the fourth preset power and the fifth preset power may be equal or unequal, and the fourth preset power and the fifth preset power are equal in the embodiment of the present invention. Specifically, as shown in fig. 4A and 4B, when the controller 13 controls the heating mechanism 12 to operate, the heating mechanism 12 is first controlled to operate at a certain power P1 for a period of time T1, the temperature inside the water cup 11 increases, the residual water decreases accordingly, when the temperature of the bottom of the water cup 11 increases to a certain temperature T1, in order to avoid an excessively high temperature at the bottom of the water cup 11, the heating mechanism 12 stops operating, the temperature at the bottom of the water cup 11 gradually decreases, when the temperature at the bottom of the water cup 11 decreases to T2, the controller 13 starts the heating mechanism 12 to operate again, and the process is repeated until the time when the temperature at the bottom of the water cup 11 increases to the preset value is less than the preset time, which indicates that the bottom of the water cup 11 is dried by distillation, and at this time.
