Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention, the refrigerator including:

a cabinet 10 serving as a support structure of the refrigerator and having a plurality of storage compartments therein;

a refrigeration system 20 for providing a refrigeration function to the refrigerator;

the ice maker 30 comprises a position switch, an ice-separating motor, an ice storage box and a plurality of ice making grids; the ice-leaving motor is connected with the ice making grid, the ice-leaving motor rotates according to a level signal of the position switch to drive the ice making grid to rotate, the level signal comprises a high level signal and a low level signal, the ice making grid is used for making ice cubes, and the ice storage box is used for storing the ice cubes;

the controller 40 is configured to:

in response to the ice making operation of the refrigerator, controlling the ice-leaving motor to rotate according to a preset first rotation strategy according to the detected level signal of the position switch; wherein the first rotation strategy comprises a forward rotation operation and a reverse rotation operation of the ice-separating motor;

after the ice making of the ice maker is finished, controlling the ice-leaving motor to rotate according to a preset second rotation strategy according to the detected level signal of the position switch; wherein the first rotation strategy includes forward and reverse rotation operations of the ice-separating motor.

It is worth mentioning that the ice maker further comprises a temperature sensor and an ice detecting rod. A user directly connects an external water source, such as tap water, with a reserved water pipe joint outside the refrigerator, then the water pipe passes through a water valve, the water valve is controlled by a controller 40, when ice making is started, whether an ice making grid is horizontal is judged by a position switch 30, the level is determined, then the controller 40 sends a signal, the water valve is opened, then water directly flows into the ice making grid, after a period of time, whether ice blocks are made or not can be judged according to a temperature value returned by a temperature sensor, if the ice blocks are made, the controller 30 controls an ice separating motor to rotate, the ice making grid is driven to rotate, and therefore the made ice blocks can be turned into an ice storage box below the refrigerator. When the ice storage box is full of ice, the ice detecting rod is lifted, the ice detecting rod rotates to trigger the position switch, and the controller 40 determines whether the ice storage box is full of ice according to a return signal of the position switch.

Specifically, in response to an ice making operation of the refrigerator, the controlling the ice-leaving motor to rotate according to a preset first rotation strategy according to the detected level signal of the position switch includes:

controlling the ice-leaving motor to execute reverse rotation operation according to a preset first operation period until the level signal of the position switch is detected to be a high level signal;

when the level signal of the position switch is detected to be a high level signal, controlling the ice-separating motor to stop in a preset first stop operation period and then executing forward rotation operation;

judging whether the level signal of the position switch is a low level signal;

if so, controlling the ice-separating motor to stop in a preset second stop operation period and then executing reverse rotation operation until the level signal of the position switch is a high level signal; if not, the forward rotation operation is continuously executed until the level signal of the position switch is a low level signal.

Further, after controlling the ice-leaving motor to perform the reverse rotation operation according to the preset first operation cycle, the controller 40 is further configured to:

when the level signal of the position switch exceeds a preset first operation time threshold value, it is determined that the ice maker 30 is out of order.

For example, referring to fig. 2, after the refrigerator is powered on, when the ice making mode is to be started, the ice maker 30 must be leveled to ensure that the ice making cells are level, and the ice making cells and the ground are level to ensure that the water flowing into each ice making cell is the same and the size of the ice cubes is the same finally.

In the process that the ice maker 30 performs initialization leveling, the level signal of the position switch is in a low level signal in an initial state, the ice-leaving motor performs reverse rotation operation according to a first operation period T1, the controller judges whether the position switch is in a high level at the moment, and if the position switch is in the high level, the ice-leaving motor is controlled to stop in a first stop operation period T1 and then forward rotation operation is performed; and if the signal is still in the low level signal, judging whether the ice separating motor fails, controlling the ice separating motor to continuously perform reverse rotation operation, and if the signal is changed into the high level signal after exceeding a first operation time threshold D1, judging that the ice separating motor fails. In the process of executing forward rotation operation of the ice-leaving motor, judging whether a position switch is a low level signal, if so, controlling the ice-leaving motor to stop in a second stop operation period t2 and then executing reverse rotation operation until the ice-leaving motor is a high level signal; and if the signal is in the high level signal, judging whether the ice-separating motor fails, controlling the ice-separating motor to continuously perform the reverse rotation operation, and if the signal exceeds a second operation time threshold D2, judging that the ice-separating motor fails. The operation direction of the ice-leaving motor is repeatedly controlled according to the detected level signal of the position switch, and it can be determined that the high level signal received at this time indicates that the ice-making tray is maintained horizontal.

Specifically, after the ice making of the ice maker 30 is completed, the controlling the ice-leaving motor to rotate according to a preset second rotation strategy according to the detected level signal of the position switch includes:

judging whether the level signal of the position switch is a low level signal;

if so, controlling the ice-leaving motor to execute reverse rotation operation until the level signal of the position switch is a high level signal, and then executing forward rotation operation until the level signal of the position switch is a low level signal; if not, controlling the ice-separating motor to execute positive rotation operation until the level signal of the position switch is a low level signal;

and after the preset time is met, when the level signal of the position switch is a high level signal, judging that the ice cubes stored in the ice storage box are full, and controlling the ice-leaving motor to perform reverse rotation operation to an initial position.

For example, referring to fig. 3, after ice making is completed, an ice turning procedure needs to be started, where the ice turning procedure is to turn an ice cube tray by a motor away from ice to turn ice cubes to turn the ice cubes into an ice storage bin below the ice cube tray. In the process, whether the position switch is a low level signal or not is judged, if yes, the ice-leaving motor is controlled to perform reverse rotation operation until the position switch is a high level signal, and then forward rotation operation is performed until the position switch is a low level signal; and if the signal is a high level signal, controlling the ice-leaving motor to execute forward rotation operation until the position switch is a low level signal. Starting to time until the preset time is met, wherein the preset time is ice making time, and judging the level signal of the position switch again; when the level signal is at a high level, the ice cubes stored in the ice storage box are judged to be full, and at the moment, the ice separating motor needs to be controlled to execute reverse rotation operation to an initial position; when the level signal is a low level signal, the ice-leaving motor is controlled to continue to execute forward rotation operation until the position switch is at a high level, the ice-leaving motor executes reverse rotation operation after stopping for a period of time, the ice-leaving motor continues to execute reverse rotation operation until the position switch is at a low level, then the ice-leaving motor continues to execute reverse rotation operation until the position switch is at a high level, timing is started for a period of time after continuing to rotate to the high level, and the process is repeatedly executed once again. When the controller receives a high level signal of the position switch after the preset time is satisfied, it may be determined that the high level signal received at this time indicates that the ice making housing is full of ice cubes.

Further, in the ice turning process, if the total time of the two ice turning times does not exceed the preset ice turning threshold time, the ice turning is judged to be normal, if the total time exceeds the preset ice turning threshold time, the ice turning fault is considered, a fault mark is set, water is not injected, the fault is checked, and a new ice making cycle is started after the fault is eliminated.

Compared with the prior art, the refrigerator disclosed by the embodiment of the invention has the advantages that the two position switches of the refrigerator in the prior art are integrated into one position switch, so that the manufacturing cost of the ice maker is saved. In addition, the controller controls the ice separating motor to rotate according to a preset first rotation strategy according to the detected level signal of the position switch, the controller continuously receives the level signal sent by the position switch in the rotation process of the ice separating motor, and when the controller receives the high level signal of the position switch for multiple times, the received high level signal can be determined to indicate that the ice cube tray is a signal for keeping the level. Similarly, after ice making is completed, the controller controls the ice-leaving motor to rotate according to a preset second rotation strategy according to the detected level signal of the position switch, the controller continuously receives the level signal sent by the position switch in the rotation process of the ice-leaving motor, and when the preset time is met and the controller receives the high level signal of the position switch, the controller can determine that the received high level signal indicates that the ice cube storage box is full of ice cubes. In addition, the high and low levels of the switch and the running time of the ice-separating motor are repeatedly detected, so that the confusion of the ice cube tray level detection signal and the ice full signal can be avoided.
