It should be noted that, the sequence of steps S2 and S3 described in the present invention may be interchanged, that is: the ice maker may control the hot tank to be heated and then control the diverting valve to conduct the second pipe and the first pipe.
After the ice maker receives a sterilization instruction sent by a user, the ice maker controls the steering valve to conduct the first pipe and the second pipe, and the circulating pipe and the second pipe are blocked by the steering valve; then the hot jar begins to heat, makes when the temperature in the hot jar reaches preset temperature, the circulating pump will hot water axial in the hot jar in the water receiving box, hot water follow the water receiving box spill out to other positions of inner bag to realize the effect that hot water disinfected to the part in the inner bag, the sterilization process need not to dismantle the ice machine, has the convenient advantage of disinfecting, and hot water sterilization has good antibacterial effect that disinfects, is favorable to guaranteeing the clean and sanitary of ice machine.
In other embodiments, as shown in fig. 4, S4. confirm that the heating time of the hot tank reaches a first preset time, and control the circulation pump to be turned on, where the preset time may be set according to the actual power of the hot tank to ensure that the water in the hot tank can be heated to an effective sterilization temperature after the hot tank is heated for the first preset time, and the preset value may be 3min to 5min, or 3min to 15min, or 1min to 30min, or 0.5min to 60 min.
Further, in this embodiment, in the step of s4. 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 hot tank heats water to 70 ℃ or above 70 ℃, the water in the hot tank flows into the liner, so that bacteria in the liner can be effectively killed, and the liner and the internal parts thereof can be cleaned. When the preset temperature is too small, the sterilization effect of the water in the hot tank is not good, and the bacteria in the inner container cannot be effectively cleared.
Further, in this embodiment, in the step of s4, confirming that the water temperature in the hot tank reaches the preset temperature, where the preset temperature is greater than or equal to 90 ℃, the hot water temperature is high at this time, the sterilization effect is good, which is beneficial to reducing the time required for sterilization and accelerating the speed of the sterilization procedure.
In other embodiments, as shown in fig. 5, the ice making machine further includes an electromagnetic valve for opening and closing the first drain port, and after the step of receiving the sterilization instruction in s1 and before the step of controlling the circulation pump to be opened in s4, the sterilization control method further includes the steps of: s5, the electromagnetic valve is controlled to open the first drainage port, the first drainage port is opened to discharge cold water in the water storage cavity, the cold water in the water storage cavity is prevented from reducing the temperature of hot water, in addition, hot water overflows from the water receiving box and is washed to directly flow out of the water storage cavity after passing through the ice receiving box, the ice storage cavity and the partition plate, and secondary pollution caused by the washed water is avoided.
In other embodiments, as shown in fig. 6, the ice maker further includes an electromagnetic valve for opening and closing the first drain opening, and after the step of controlling the circulation pump to be opened in s4, the method further includes the steps of: s6, the electromagnetic valve is controlled to be opened after the circulating pump is started for a second preset time, so that hot water stays in the inner container for the second preset time to guarantee the bacteria killing effect of the hot water, and specifically, the second preset time can be 0.5-30 min, 2-20 min, 5-10 min and the like, and the sterilizing effect is good.
The ice maker and the sterilization control method thereof of this embodiment are not limited to the above 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 circulation pump to be opened in s4, the sterilization control method further includes the steps of: s7, after the circulating pump works for a third preset time, controlling the steering valve to conduct the circulating pipe and the second pipe; s8, after the circulating pump continues to work for a fourth preset time, the electromagnetic valve is controlled to open the first water discharging opening, the third preset time can be 5-10 min, also can be 1-15 min, and also can be 0.5-30 min, the fourth preset time can be 5-10 min, also can be 1-15 min, and also can be 0.5-30 min, and the fourth preset time when the circulating pump continues to work can repeatedly pump hot water from the water storage cavity to the water receiving box, so that parts in the inner container can be repeatedly washed, and the sterilizing and cleaning effects are good.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
