The refrigeration system is used for providing cold energy to the ice making assembly. The ice-making assembly is used for making ice cubes. Alternatively, the ice-making assembly may include, for example, a barrel, a screw ice-making lever rotatably coupled within the barrel, and a drive device drivingly coupled to the screw ice-making lever.

The water inlet of the water discharge valve 18 is connected with the ice making barrel, the water discharge valve 18 is arranged on the shell 10, the water outlet of the water discharge valve 18 is suspended above the water receiving box 20, and the water discharge valve 18 is used for discharging waste water in the ice making barrel into the water receiving box 20. Alternatively, the waste water may include washing water of the ice making tub, defrosting water, thawing water, and the like.

A controller is electrically connected to the first sensor 16, the ice making system 17 and the drain valve 18, respectively, the controller being configured to: determining whether the water receiving box 20 is connected to the assembling position based on the detection result of the first sensor 16; if not, the ice making system 17 is allowed to perform an ice making operation, and the drain valve 18 is closed to prohibit the discharge of waste water through the drain valve 18. Alternatively, the first inductor 16 may be configured to: if it is determined that the water receiving box 20 is connected to the mounting position, a first signal is sent to the controller, and if it is determined that the water receiving box 20 is not connected to the mounting position, a second signal is sent to the controller.

In conjunction with the illustration of fig. 5, the controller may obtain a first instruction for instructing to perform a defrosting operation. Alternatively, the first instruction may be automatically generated by the controller based on the sensing result of the sensor. For example, the controller may generate a first command when it is determined 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 member such as an operation panel. For example, the user may select a key or option on the operation panel that performs a defrosting operation, and the operation panel sends a first instruction to the controller.

In conjunction with the illustration of fig. 6, the controller may also obtain a second instruction for instructing to perform a cleaning operation. Similar to the first instruction, the second instruction may also be automatically generated by the controller based on control logic or retrieved from an operating component such as an operating panel. For example, before the start of the ice making operation, after a preset period of time of the ice making operation is performed, or automatically in response to other control logic. For example, the operation panel may send a first instruction to the controller in response to a user selection of a cleaning operation.

After the controller acquires the second instruction, it may be determined whether the water receiving case 20 is connected at the assembly position based on the detection result of the first sensor 16, and if it is determined that the water receiving case 20 is connected at the assembly position, the ice making system 17 is instructed to perform the washing operation based on the second instruction, and the drain valve 18 is opened, so that the formed washing water can be discharged to the water receiving case 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 may further determine whether the water receiving tank 20 is connected to the assembling position again after the ice maker stands by for a preset period of time, control the ice making system 17 to perform the washing operation based on the second instruction if it is determined that the water receiving tank 20 is connected to the assembling position, and continuously control the ice maker to maintain the stand-by state if it is still determined that the water receiving tank 20 is not connected to the assembling position.
