and S14, after the ice maker is controlled to stop injecting water into the ice making box, the ice maker is controlled to perform a refrigerating operation on the ice making box.
In the embodiment of the present invention, when a user has an ice making requirement, an ice making instruction including information on the size of ice pieces to be made and an ice making start instruction is input through the display panel 13.
In one embodiment, an indication bar and an indication slider for indicating ice size information are provided on the display panel 13, and a user slides the indication slider to make the indication slider perform a cyclic display of ice size from left to right, and when the ice size information is slid to a size of ice desired by the user, the user releases the indication slider to locate the ice size information desired by the user. Further, the user presses the ice making start button on the display panel again, at which time the input of the ice making command by the user is completed, and the display panel 13 transmits the ice making command to the controller 15.
In another embodiment, a selection key of ice size information is arranged on the display panel 13, when a user presses the selection key, a plurality of option keys displaying ice sizes are popped up on a display interface of the display panel, and the user presses the corresponding option keys according to the ice making requirement of the user, so that the display panel obtains the ice size information required by the user. Further, the user presses the ice making start button on the display panel again, at which time the user's ice making command input is completed, and the display panel 13 transmits the ice making command to the controller 15.
It can be understood that the above input manner of the ice making instruction of the user is only an example, and in practical applications, different input manners may be set according to requirements, without affecting the beneficial effects obtained by the present invention.

And correspondingly distributing the water injection amount of each ice making case according to the number of the ice making cases in the ice making box. For example, if an ice cube is of a size a and the corresponding water injection amount is 15ml, the flow meter will send 70 pulse signals when detecting that the water injection amount increases from 0 to 15ml, and the ice making box includes 6 ice making cells, then in the mapping relationship, the number of the pulse signals corresponding to the size of the ice cube is 420.
Furthermore, when receiving an ice making instruction of a user, the controller 15 obtains the ice cube size information carried in the ice making instruction, and calls the mapping relationship to find the pulse signal number corresponding to the ice cube size made by the user as a target pulse signal number, so as to control the water injection amount of the ice maker according to the target pulse signal number.
And after the target pulse signal number is determined, controlling the ice maker to fill water into the ice making box, and counting pulse signals output by the flowmeter. The ice maker can inject water into each ice making grid according to the number of the target pulse signals so as to enable the water injection amount of each ice making grid to reach the water injection amount corresponding to the size of the formed ice cubes.
When detecting that the accumulated number of the pulse signals output by the current flowmeter reaches the target pulse signal number, indicating that the operation of injecting water into each ice making grid in the ice making box is finished, controlling the ice making machine to stop injecting water into the ice making box, and then controlling the ice making machine to perform refrigeration operation on the ice making box so as to enable water in the ice making grids to form ice blocks.
Preferably, after controlling the ice maker to stop filling water into the ice making housing, the controller is further configured to perform step S15:
and S15, clearing the accumulated number of the pulse signals output by the flowmeter.

By adopting the embodiment of the invention, the ice cubes with required sizes can be made by controlling the single water injection amount, the requirements of users on the ice cubes with different sizes are met, an ice crusher is not required to be additionally arranged to crush the ice cubes, and additional manual operation is not required, so that the product cost is saved, and the use experience of the users is improved.
Referring to fig. 3-4, fig. 3 is a schematic structural diagram of a refrigerator according to another embodiment of the present invention; fig. 4 is a schematic flowchart of a controller in a refrigerator according to an embodiment of the present invention. On the basis of the above embodiment, the refrigerator 10 further includes: an in-box temperature sensor 16 and an ice-making housing temperature sensor 17.
The inside temperature sensor 16 is disposed in the refrigerator body 11, and is configured to detect a current inside temperature of the refrigerator. The ice making box temperature sensor 17 is disposed in the ice maker 12, and is configured to detect a current ice making box temperature of the ice maker.
The controller 15 is further connected to the inside temperature sensor 16 and the ice-making box temperature sensor 17, and configured to obtain an inside temperature detected by the inside temperature sensor 16 and an ice-making box temperature detected by the ice-making box temperature sensor 17.
Then, the step S14 executed by the controller 15 specifically includes steps S141 and S142:
and S141, after the ice maker is controlled to stop injecting water into the ice making box, calculating the ice making time of the ice maker according to the temperature in the box, the temperature of the ice making box and the size information of the ice cubes.
And S142, controlling the ice maker to execute refrigeration operation on the ice making box according to the ice making time length.
Specifically, a functional relation T = f (T = f) of the in-box temperature, the ice-making box temperature, the ice-cube size, and the ice-making time length is obtained by fitting through experiments performed for a plurality of times in advance (T is a time length of ice making) 1 ，T 2 V); wherein T is the ice making time period T 1 Is the temperature in the tank, T 2 V is the ice cube size for the ice cube tray temperature.
Specifically, in the functional relation, the ice making time t has a positive correlation with the temperature in the box, a positive correlation with the temperature of the ice making box, and a positive correlation with the size of the ice cubes.
And when the ice making time length of the ice making machine in the ice making control round is obtained through calculation, the ice making machine is controlled to carry out the refrigeration operation of the ice making box according to the ice making time length.
By adopting the technical means of the embodiment of the invention, the ice making time length of the ice maker can be accurately controlled by combining the temperature in the ice box, the temperature of the ice making box and the size of ice cubes, the waiting time of a user is saved on the basis of ensuring the quality of the made ice cubes, and the use experience of the user is further improved.
As a preferred implementation manner, on the basis of the above embodiment, after the step S12 is executed, the controller is further configured to execute a step S13':
s13', after a first preset time period elapses from the time when the ice maker injects water into the ice making box, detecting whether the ice maker stops injecting water into the ice making box; and when the ice maker is not stopped injecting water into the ice making box, controlling the ice maker to stop injecting water into the ice making box.
In the embodiment of the invention, a first preset time length is preset and used as a protection mechanism for the water filling process of the ice machine. In some special cases, the period of the output pulse signal of the flow meter 14 is longer and the water filling time is longer due to the fact that the water pressure of the water tank of the ice machine is small or the water quantity is insufficient. At this time, in order to avoid the influence on the progress of the subsequent ice making operation, a long waiting time of the user is avoided. After a first preset time period from the time when the ice machine injects water into the ice making box, the ice machine still injects water into the ice making box, the ice machine is directly controlled to stop injecting water into the ice making box, and the step S14 is skipped to, and the ice machine is controlled to execute the refrigeration operation on the ice making box.
Preferably, after controlling the ice maker to stop filling water into the ice making housing, the controller is further configured to perform step S15:
and S15, clearing the accumulated number of the pulse signals output by the flowmeter.
By adopting the technical means of the embodiment of the invention, the smooth proceeding of the ice making work can be ensured, the long waiting time of the user under the condition that the user urgently needs ice blocks is avoided, and the use experience of the user is further improved.
As a preferred embodiment, after the controller executes the step S12, the controller is further configured to execute a step S16:
s16, when detecting that the accumulated number of the pulse signals output by the current flowmeter does not reach the target number of the pulse signals and the pulse signals output by the flowmeter are not received within a second preset time, judging that the flowmeter is in a fault state; and controlling the ice maker to stop injecting water into the ice making box after a third preset time period from the moment when the flow meter is judged to be in the fault state.
Further, after the determination that the flow meter is in the failure state, the controller is further configured to execute step S17:
and S17, judging that the flowmeter is in a normal state when the pulse signal output by the flowmeter is detected again.
In the embodiment of the invention, the fault detection of the flow meter is realized by setting a second preset time length, and the water injection quantity control of the ice maker after the flow meter is in fault is realized by setting a third preset time length. The second preset time period and the third preset time period may be set according to actual conditions, for example, both set to 5 seconds.
And in the process that the controller 15 does not detect that the accumulated number of the pulse signals output by the flowmeter reaches the target number of the pulse signals, controlling the ice maker to inject water into the ice making box, and in the process, if the feedback of the pulse signals is not detected for 5 seconds continuously, determining that the flowmeter 14 is in a fault state and the water injection fails, and reporting that the flowmeter 14 is in a fault state by the controller to remind a user of checking, maintaining or replacing the flowmeter.
And, in order to guarantee the smooth progress of water injection, the ice maker is controlled to perform water injection operation to the ice making housing for 5 seconds from the time when the flow meter is determined to be in the failure state. And after 5 seconds of water injection, controlling the ice maker to stop injecting water, jumping to a step S14, and controlling the ice maker to perform a refrigerating operation on the ice making box.
Preferably, the controller is further configured to execute step S18:
s18, counting the number of times that the flowmeter is in a fault state; and when the number of times that the flow meter is in the fault state is detected to reach the preset fault number, judging that the ice maker is in the water-free state.
Preferably, after the controller executes step S17, that is, after determining that the flow meter is in a normal state, the controller is further configured to execute step S19:
and S19, when the accumulated number of the pulse signals output by the flowmeter is detected to reach the preset number of the pulse signals, clearing the number of times that the flowmeter is in the fault state.
In the embodiment of the invention, after the flowmeter is detected to be in the fault state, the number of times that the flowmeter is in the fault state is increased by 1. In each ice making round of the ice maker, once the flow meter is detected to be in a fault state, the number of the fault states is increased by 1. And clearing the number of times that the flowmeter is in a fault state until the accumulated number of the pulse signals output by the flowmeter reaches the preset number of the pulse signals, for example, 100, which indicates that the flowmeter has been normally used for a long time, and subsequently continuing to accumulate the number of times of faults. Before the failure times are not cleared, when the failure times reach a certain number, for example, three times, it is detected that the flow meter is detected to be in a failure state for many times within a certain time, and at this time, it may be that the flow meter fails but that water is not stored in the water tank of the ice maker, and the controller determines that the ice maker is in a water-free state and reports the water-free state to remind a user of checking and adding water to the water tank of the ice maker.
By adopting the technical means of the embodiment of the invention, in the water injection process of the ice maker, when the accumulated number of the detected pulse signals does not reach the target pulse signal number but the feedback of the pulse signals is not continuously detected, no matter the flow meter is in failure or the ice maker is not water-free, the ice maker is controlled to perform water injection for a certain time and then stop water injection operation, and the ice making box is refrigerated, so that the smooth proceeding of ice making work is ensured, the invalid waiting time of a user is avoided under the condition that the user urgently needs ice blocks, and the use experience of the user is further improved.
