Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of control device of refrigerator, as shown in Figure 1, the control device of refrigerator specifically includes detection
Module 11, interlocking module 12 and drive module 13: where
Detection module 11, in the course of work of refrigerator, whether real-time detection power supply to be abnormal;
Preferably, detection module 11 is specifically used for: the feedback end at forceful electric power end and power module to refrigerator is examined respectively
It surveys;
When forceful electric power end detection voltage be lower than the first preset threshold, and the detection voltage of feedback end be lower than the second preset threshold
When, then determine that power down or operation irregularity occur for power supply, otherwise determines that power work is normal.
Here forceful electric power end refers to the voltage incoming end (such as 220V) of refrigerator, power module refer to be each negative in refrigerator
It carries and the power module of operating voltage is provided, be the core output terminal of entire circuit control system.Detection module 11 only works as forceful electric power
When the electric voltage exception at end and the provided voltage of power module abnormal simultaneously, i.e. the power supply of judgement refrigerator is abnormal, and
When any Rule of judgment is unsatisfactory for, then determine that power supply works normally.
Interlocking module 12, the water receiver for controlling refrigerator bottom are released.
Wherein, interlocking module 12 refer to control water receiver state change mechanical structure, generally include motor, sliding rail,
Link mechanism and water receiver etc..It can control link mechanism, sliding rail by motor to release water receiver, be in water receiver and receive
Receive state.Wherein, abnormal control signal is to be triggered by drive module 13 according to the testing result of detection module 11.
Preferably, when the motor in interlocking module 12 can will be in receiving state with Reverse Turning Control link mechanism, sliding rail
Water receiver withdraw.It is found that in the present invention state of entire water receiver change, be all by interlocking module 12 according to control signal
It completes, without artificial operation and intervention.
Drive module 13, for being controlled according to the exception of detection module 11 when detection module 11 detects power supply and is abnormal
The water receiver that signal processed driving interlocking module 12 will be located at refrigerator bottom is released, with what is melted after being powered off refrigerator by water receiver
Water is stored.
Preferably, drive module 13 are also used to detect that reseting controling signal driving interlocking module 12 will be in storage
The water receiver of state is withdrawn.Here reseting controling signal is triggered by user, when user determines the water process in water receiver
After the completion, reseting controling signal is sent by reset key.Driving unit controls interlocking module 12 instead according to the reseting controling signal
Turn to withdraw water receiver.
