After receiving a sterilization instruction sent by a user, the ice maker controls the steering valve to conduct the first pipe and the second pipe, and at the moment, the space between the circulating pipe and the second pipe is blocked by the steering valve; then the hot jar begins the heating for when the temperature of water in the hot jar reaches the preset temperature, the circulating pump will the hot water in the hot jar is axial in the water receiving box, the hot water is followed the water receiving box is diffused to other positions of inner bag, with the effect that the part in the realization hot water to the inner bag was disinfected, the sterilization process need not to dismantle the ice machine, has the convenient advantage of disinfecting, and hot water sterilization has good bactericidal antibacterial effect, is favorable to guaranteeing the clean health of ice machine.
In other embodiments, as shown in fig. 4, S4 may also be used to confirm that the heating time of the hot tank reaches a first preset time, and control the circulation pump to be started, where the preset time may be set according to the actual power of the hot tank, so as to ensure that the water in the hot tank can be heated to an effective sterilization temperature after the hot tank heats the first preset time, and the preset value may be 3min to 5min, 3min to 15min, 1min to 30min, or 0.5min to 60 min.
Further, in this embodiment, in the step s4 of confirming that the water temperature in the hot tank reaches a preset temperature, the preset temperature is greater than or equal to 70 ℃. When the water is heated to 70 ℃ or above 70 ℃ by the hot tank, the water in the hot tank flows into the inner container, so that bacteria in the inner container can be effectively killed, and meanwhile, the inner container and internal components thereof can be cleaned. When the preset temperature is too small, the sterilization effect of the water in the hot tank is poor, and bacteria in the inner container cannot be effectively cleared.
Further, in this embodiment, in the step s4 of determining that the water temperature in the hot tank reaches the preset temperature, the preset temperature is greater than or equal to 90 ℃, and at this time, the temperature of the hot water is high, so that the sterilization effect is good, the time required for sterilization is reduced, and the speed of the sterilization procedure is accelerated.
In other implementations, as shown in fig. 5, the ice maker further includes an electromagnetic valve for opening and closing the first drain port, and after the step of receiving the sterilization command, and before the step of controlling the circulation pump to be opened in step s4, the sterilization control method further includes the steps of: s5, controlling the electromagnetic valve to open the first water outlet, opening the first water outlet to discharge cold water in the water storage cavity, and avoiding the cold water in the water storage cavity from reducing the temperature of hot water.
In other implementations, as shown in fig. 6, the ice maker further includes an electromagnetic valve for opening and closing the first drain port, and after the step of controlling the circulation pump to be opened in s4, the sterilization control method further includes the steps of: s6, controlling the electromagnetic valve to be opened after the circulating pump is opened for a second preset time period, so that the hot water stays in the inner container for the second preset time period to ensure the sterilization effect of the hot water, specifically, the second preset time period can be 0.5-30 min, can be 2-20 min, can be 5-10 min and the like, and has the characteristic of good sterilization effect.
The ice maker and the sterilization control method thereof according to the present embodiment are not limited to the above-mentioned technical solution, and in other implementations, the ice maker further includes an electromagnetic valve for opening and closing the first drain port, and after the step of controlling the opening of the circulation pump in s4, the sterilization control method further includes the steps of: s7, controlling the steering valve to conduct the circulating pipe and the second pipe after the circulating pump works for a third preset time period; s8, after the circulating pump continues to work for a fourth preset time period, the electromagnetic valve is controlled to open the first water outlet, the third preset time period can be 5-10 min, 1-15 min or 0.5-30 min, the fourth preset time period can be 5-10 min, 1-15 min or 0.5-30 min, and the circulating pump continues to work for the fourth preset time period, so that hot water can be repeatedly sent from the water storage cavity to the water receiving box, repeated flushing of parts in the liner is achieved, and the circulating pump has the characteristics of good sterilizing and cleaning effects.
The foregoing description is only of the optional embodiments of the present invention, and is not intended to limit the scope of the invention, and all the equivalent structural changes made by the description of the present invention and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the invention.
