As shown in conjunction with fig. 5, the controller may obtain a first instruction for instructing a defrosting operation to be performed. Alternatively, the first instruction may be automatically generated by the controller based on a sensing result of the sensor. For example, the controller may generate the first command when determining that the ice making tub is frozen based on a sensing result of the sensor. Alternatively, the controller may acquire the first instruction from an operation unit such as an operation panel. For example, the user may select a key or an option on the operation panel to perform a defrosting operation, and the operation panel sends a first instruction to the controller.

After the controller acquires the first instruction, whether the water receiving box 20 is connected to the assembly position can be judged based on the detection result of the first sensor 16, if the water receiving box 20 is determined to be connected to the assembly position, the ice making system 17 is controlled to perform defrosting operation based on the first instruction, the drain valve 18 is opened, and formed defrosting water can be discharged to the water receiving box 20 through the drain valve 18. If it is determined that the water receiving box 20 is not connected at the assembling position, the ice maker is controlled to be in a standby state. The controller can also judge whether the water receiving box 20 is connected at the assembly position again after the ice machine is in a standby state for a preset time, if the water receiving box 20 is determined to be connected at the assembly position, the ice making system 17 is controlled to perform defrosting operation based on the first instruction, and if the water receiving box 20 is determined not to be connected at the assembly position, the ice machine is controlled to keep the current standby state.

As shown in fig. 6, the controller may also obtain a second instruction for instructing execution of the washing operation. The second instruction may be automatically generated by the controller based on the control logic, or may be acquired from an operation member such as an operation panel, similarly to the first instruction. For example, before the ice making operation is started, after the ice making operation is performed for a preset time period, or automatically in response to other control logic. Also for example, the operator panel may send a second instruction to the controller in response to user selection of a cleaning operation.

After the controller acquires the second instruction, whether the water receiving box 20 is connected to the assembly position may be determined based on the detection result of the first sensor 16, and if it is determined that the water receiving box 20 is connected to the assembly position, the ice making system 17 may be instructed to perform a washing operation based on the second instruction, and the drain valve 18 may be opened, and the formed washing water may be discharged to the water receiving box 20 via the drain valve 18. If it is determined that the water receiving box 20 is not connected at the assembling position, the ice maker is controlled to be in a standby state. The controller can also judge whether the water receiving box 20 is connected at the assembly position again after the ice machine is in a standby state for a preset time, if the water receiving box 20 is determined to be connected at the assembly position, the ice making system 17 is controlled to execute the cleaning operation based on the second instruction, and if the water receiving box 20 is still determined not to be connected at the assembly position, the ice machine is continuously controlled to keep the standby state.
