Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the subject matter of the present application can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the application.

The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

Fig. 1 is a schematic view of an ice making principle of an ice making device in the related art of the present application. As shown in fig. 1, an output rotating shaft (not shown in the figure) of the ice scraping motor rotates along an axis to drive the ice scraping rod 101 to rotate, the ice scraping rod 101 can rotate clockwise or anticlockwise, an arc-shaped ice making container 103 is arranged below the ice scraping motor, the ice making container 103 is used for containing water to be made with ice, a position switch is arranged on a rotating track of the ice scraping output rotating shaft, the position switch can be a copper sheet, when the output rotating shaft reaches the position of the copper sheet, a circuit connected with the copper sheet is triggered to generate a trigger signal, and the trigger signal can be used for judging the starting and ending positions of the ice scraping motor.

However, since the copper sheet has a physical volume, the position switch will be in a triggered state in the rotation area of the ice scraping bar. After ice is made for many times, the specific position of the ice scraping rod is difficult to be accurately determined only by the trigger signal of the position switch. Illustratively, the rotation area 102 of the ice scraping bar can be divided into two areas, namely an area a and an area B, wherein the position switch of the area a is in an open state, and the position switch of the area B is in a closed state, i.e. is triggered. If the ice making device only determines the position of the ice scraping rod through the position switch, the ice scraping rod can only be identified to stay in the area A or the area B, and further accurate position judgment cannot be carried out. If the ice scraping rod is located at the lower side of the B area, that is, at a position close to the ice making container, the ice scraping rod may contact water or water vapor to be made ice, and may be frozen in ice blocks.

Based on the ice making principle of the ice making device shown in fig. 1, fig. 2 is a flowchart of a control method of the ice making device according to an embodiment of the present application. The ice making device has an ice scraping lever having a reference position at which a position sensor is provided. The position sensor may also be a position switch as shown in fig. 1. As shown in fig. 2, the control method of the ice-making device includes at least the following steps S210 to S230.

And step S210, responding to an initialization signal of the ice scraping rod, and controlling the ice scraping rod to rotate along a first direction.

The initialization signal of the ice scraping lever is used to instruct the ice scraping lever to return to an initial position in preparation for ice making. In the initialization process of the ice scraping rod, the ice scraping rod is firstly controlled to rotate in a first direction. The first direction can be clockwise or anticlockwise, and the step aims to preliminarily determine the position of the ice scraping rod through the combination of the rotation of the ice scraping rod and a trigger signal of the position sensor, so that subsequent operation is facilitated.

In one embodiment, step S210 may specifically be: responding to an initialization signal of the ice scraping rod, and controlling the ice scraping rod to rotate by a first angle along a first direction; in the process of rotating the ice scraping rod by the first angle, if the position sensor is not monitored to be triggered, the ice scraping rod is controlled to continue to rotate along the first direction until the position sensor is triggered.

In another embodiment, step S210 may further specifically be: the ice scraping rod is controlled to rotate in the first direction for a first preset time, and the first preset time is shorter than the time required for the ice scraping rod to rotate for a circle. For convenience of illustration, the product of the first predetermined period of time and the rotational speed of the motor may be the first angle.

The first angle is the maximum angular range over which the ice-scraping lever is expected to trigger the position sensor, and for example, the first angle may be set to an angle between two boundaries of the B-zone. Typically, the ice scraping bar is rotated in a first direction by a first angle and the position sensor will be triggered. In the process of rotating the ice scraping rod by the first angle, if the position sensor is not triggered, the ice scraping rod is controlled to continue rotating along the first direction until a signal that the position sensor is triggered is detected.

Further, in another embodiment, if the position sensor is not monitored to be triggered within a time period required by the ice scraping rod rotating for more than or equal to one circle along the first direction, it can be preliminarily determined that the ice scraping rod is frozen, at the moment, the heater is started to heat, so that an ice layer condensed on the ice scraping rod is melted, the ice scraping rod is controlled to rotate after the ice layer is melted, faults caused by freezing of the ice scraping rod are eliminated, and the working stability of the ice making device is improved.

And step S220, monitoring the state of the position sensor in the rotation process of the ice scraping rod.

During rotation of the ice scraping bar in the first direction, a state of the position sensor is monitored. In one embodiment, if the first direction is counterclockwise, the reference position may be a position of an upper boundary of the B region in fig. 1. Specifically, if the position of the upper boundary of the B region in fig. 1 is set as the reference position, it is possible to determine whether the ice scraping lever reaches the reference position by detecting a transition signal from on to off of the position switch. In another embodiment, if the first direction is clockwise, the reference position may be a position of a lower boundary of the B zone in fig. 1, and similarly, whether the ice scraping lever reaches the reference position may be determined by detecting a transition signal from on to off of the position switch, where the reference position is the position of the lower boundary of the B zone.

In another embodiment, when the ice making device is provided in the refrigerating compartment of the refrigerator, the generating process of the ice making device initialization signal may include the steps of: monitoring the on-off state of the refrigerator, wherein the on-off state comprises a power-on state and a power-off state; and if the refrigerator enters the power-on state from the power-off state, generating an initialization signal of the ice scraping rod.

Specifically, after the refrigerator is powered on every time, an initialization signal of the ice scraping rod is generated so as to determine the position of the ice scraping rod again. Thereby increasing operational reliability and stability of the ice making device provided in the refrigerator.

In step S230, if it is monitored that the position sensor is triggered, the ice scraping lever is controlled to rotate from the reference position for a set time period and then stop, and the current position of the ice scraping lever is set as the initial position.

The reference position is a known position, such as the position of the lower boundary of the B-zone, the position of the upper boundary of the B-zone, and so on. The initial position of the ice scraping rod needs to be arranged at a position which is beneficial to scraping ice and not easy to freeze. Illustratively, the initial position may be set at a position on the upper half of the area B in fig. 1, so that the ice scraping bar is far away from moisture and can quickly reach the ice making container when scraping ice. The ice scraping rod rotates from the reference position for a set time and then reaches the initial position. It should be noted that the angle between the reference position and the initial position is known, and the product of the set time length and the rotation speed of the ice scraper is the known angle.

Therefore, the initial position is determined through the reference position calibrated by the position sensor, and the initial position is set as the position to be returned by the ice scraping rod after each initialization, so that the specific position of the ice scraping rod can be accurately determined, and the reliable control of the ice making device is guaranteed.

In one embodiment, the step S230 of controlling the ice scraping lever to rotate from the reference position for the set time period and then stop may specifically include the following steps: and controlling the ice scraping rod to rotate from the reference position along a second direction for a set time length, and then stopping the ice scraping rod, wherein the second direction is the opposite direction of the first direction, and the set time length is the time length of the ice scraping rod rotating from the reference position to the set initial position.

If the first direction is in the anticlockwise direction, when the position sensor is triggered, if the trigger signal is from closing to opening, the position of the ice scraping rod on the upper boundary of the area B in the figure 1 can be determined, and then the ice scraping rod is controlled to rotate clockwise from the position of the upper boundary of the area B for a set time length and then stop, and the ice scraping rod reaches the initial position. Therefore, the ice scraping rod can reach the initial position set by the ice scraping rod, namely the optimal stop position, through the reference position of the position sensor.

If the first direction is clockwise, when the position sensor is monitored to be triggered, if the trigger signal is from closing to opening, the ice scraping rod is determined to be located at the position of the lower boundary of the area B in the figure 1, and then the ice scraping rod is controlled to rotate in the anticlockwise direction for a set time length, wherein the set time length is the time length required for reaching the set initial position from the position of the lower boundary of the area B.

As described above, the set initial position is the optimal stop position set when the ice scraping rod is idle, so that the ice scraping rod can quickly reach the set initial position by rotating in the opposite direction of the first direction after the position sensor is triggered, the probability of freezing of the ice scraping rod is reduced, and the working efficiency of the ice making device is improved.

Fig. 3 is a flowchart of a method of controlling an ice making device according to an embodiment of the present application. As shown in fig. 3, the ice-making device control method includes the steps of:

step S301, if the refrigerator enters the power-on state from the power-off state, generating an initialization signal, and entering step S210;

step S210, responding to an initialization signal of the ice scraping rod, and controlling the ice scraping rod to rotate along a first direction;

step S303, in the execution process of step S210, monitoring whether the position sensor is triggered, if so, entering step S230, and if not, entering step S220;

step S230, controlling the ice scraping rod to rotate from the reference position for a set time length and then stop, and entering step S304 when the current position of the ice scraping rod is the initial position;

step S220, controlling the ice scraping rod to continuously rotate along the first direction;

step S305, during the execution of step S220, monitoring whether the position sensor is triggered, if so, executing step S230, and if not, executing step S306;

step S306, judging whether the ice scraping rod rotates along the first direction for a second preset time, if so, entering step S307, and if not, executing step S220;

step S307, heating the ice scraping rod until a preset heating stop condition is reached, and executing step S308;

step S308, judging whether the preset heating times are reached, if so, entering step S309, otherwise, entering step S220;

step S309, initialization fails;

in step S304, the initialization is successful.

It should be noted that the second preset time period and the preset heating times can be specifically set according to specific situations, and the control method of the refrigeration apparatus shown in fig. 3 is consistent with the inventive concept of the foregoing embodiment, and is not described herein again.

Fig. 4 is a flowchart of a method of controlling an ice making device according to another embodiment of the present application. As shown in fig. 4, after the ice scraping lever reaches the initial position, if the ice making signal is received, the ice making device control method of this embodiment may further include the following steps S410 to S440.

Step S410, responding to the ice-making signal, controlling the ice-making device to make ice;

step S420, after ice making is finished, in response to an ice scraping signal, controlling the ice scraping rod to rotate for a third preset time length along the set ice scraping direction so as to scrape ice, wherein the third preset time length is the time length required by one-circle rotation of the ice scraping rod;

step S430, monitoring the state of the position sensor in the rotating process;

in step S440, if the position sensor is triggered, it is determined that the ice scraping lever returns to the initial position.

Specifically, after the initialization process is completed, the ice scraping rod is located at the set initial position. After the controller receives or produces an ice making signal, the controller controls the ice making device to make ice, wherein the ice making signal can be triggered manually or automatically by the system.

The completion of the ice making process can be sensed by a temperature sensor arranged on the ice making container, and specifically, if the temperature of the ice making container sensed by the temperature sensor is lower than zero, the completion of the ice making can be determined. The completion of the ice making process may also be identified by an ice making time period, illustratively, the completion of ice making may be determined after the ice making time period exceeds the expected ice making time period. The completion of the ice making process can be determined by the ice detecting rod according to the difference of the hardness of ice water.

After ice making is completed, an ice scraping signal is waited, and the ice scraping signal can be triggered manually or automatically by a system, which is not limited herein. When the ice scraping signal is received or produced, the controller controls the ice scraping rod to rotate for a third preset time along the set ice scraping direction, and the third preset time can be set as the time required by one-circle rotation of the ice scraping rod. Therefore, the ice scraping operation can be finished, and the ice scraping device can return to the set initial position. When the ice scraping rod returns to the initial position, the position sensor is triggered under normal conditions. Thus, the state of the position sensor can be monitored during rotation; if the position sensor is triggered, it is determined that the ice scraping lever is actually returned to the initial position.

Fig. 5 is a flowchart of a method of controlling an ice making device according to another embodiment of the present application. And in the process that the ice scraping rod rotates for a third preset time length along the set ice scraping direction, if the position sensor is not triggered, the abnormal condition is indicated. Due to the special nature of the ice-scraping bar, which is easily frozen by ice, the situation that needs to be excluded first is that in which the ice-scraping bar is frozen. Therefore, as shown in fig. 5, in this embodiment, after step S430, the method of controlling the ice making device may further include the steps of:

step S505, if the position sensor is not triggered, the ice scraping rod is controlled to continue to rotate along the set ice scraping direction for a fourth preset time, and the fourth preset time is longer than a third preset time;

step S506, monitoring the state of the position sensor, if the state is triggered, entering step S440, determining that the ice scraping rod returns to the initial position, and if the state is not triggered, entering step S507;

step S507, judging whether the preset heating times are reached; if yes, go to step S508, otherwise, go to step S509;

step S508, issuing a failure notification of the ice making device;

and step S509, heating the ice scraping rod again until the preset heating stop condition is met, and circularly executing the step S505 after the heating is finished.

Illustratively, the fourth preset duration may be set to an integer multiple, e.g., three times, of the third preset duration. Therefore, after the ice scraping rod is controlled to rotate for the fourth preset time, if the ice scraping rod is not frozen, the ice scraping rod can just return to the initial position. The preset heating times can be set to three times, so that after the heating and the rotation of the three times, if the situation that the position sensor is triggered is not monitored, a fault notification of the refrigerating device is sent. Therefore, through the steps, the condition that the ice scraping rod is frozen and frozen can be eliminated, and the occurrence rate of fault notification is reduced.

In one embodiment, after the notification of the malfunction of the ice scraping lever is issued, the method of controlling the ice making device may further include the steps of: measuring the opening and closing state of a refrigerating chamber door body, wherein the opening and closing state comprises an opening state and a closing state; recording the duration of each open state; and if the duration corresponding to one opening state is greater than a preset duration threshold, generating an initialization signal of the ice scraping rod after entering the closing state from the opening state.

Specifically, since the ice making device is disposed in the refrigerating chamber of the refrigerator, and a user or a serviceman maintains the ice making device after the ice making device gives a fault notification, an initialization signal of the ice scraping lever may be generated after the door of the refrigerating chamber is opened for a preset time threshold, so as to retry initialization, thereby ensuring the reliability of the operation of the ice making device.

According to another aspect of embodiments of the present application, there is also provided an ice making apparatus including at least an ice making container, an ice scraping bar, a heater, a position sensor, and a controller. The ice making container is used for containing water to be made ice; the ice scraping rod is arranged on the upper side of the ice making container and used for scraping ice blocks out of the ice making container after receiving an ice scraping signal; the heater is used for heating the ice scraping rod; the position sensor is arranged at the reference position of the ice scraping rod; the controller is used for responding to the initialization signal of the ice scraping rod and controlling the ice scraping rod to reach the initial position through the reference position identified by the position sensor.

In one embodiment, the controller controls the ice scraping lever to return to the initial position when the ice making device is powered on. Specifically, the controller controls the ice scraping rod to continue rotating for a preset angle and then stop through the reference position identified by the position sensor, the ice scraping rod reaches the initial position, and the initialization of the ice scraping rod is completed after the ice scraping rod reaches the initial position. In further embodiments, the method of controlling the ice making container may be any of the ice making device control methods as previously described.

After receiving or generating the ice making signal, the controller controls water to be filled into the ice making container and supplies cold to the ice making container to make the water of the ice making container into ice.

The heater may be directly used to heat the ice scraping bar, and may also heat the ice making container to heat the ice scraping bar through the ice making container. When the heater is disposed at the lower side of the ice making container, the heater may also heat the ice making container, so that the ice cubes in the ice making container are easily separated from the ice making container. In one embodiment, the heater may be a heating wire closely attached to the bottom of the ice making container.

Further, the ice making device may further have a temperature sensor, and the temperature sensor may be disposed at the bottom of the ice making container, and the ice making time and the heater heating time may be controlled by the temperature sensor. That is, whether ice is finished or not is judged by the temperature sensor, and whether heating is finished or not is judged by the temperature sensor to further generate an ice making completion signal or further judge whether ice is frozen on the ice scraping lever or not.

According to another aspect of the present application, there is also provided a refrigerator having a refrigerating compartment, the ice making device as described above, and a refrigeration cycle system. A refrigeration cycle of a refrigerator is generally a closed refrigerant cycle formed by combining a compressor, a condenser, a dry filter, a capillary tube, an evaporator, and the like.
