Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
The control method of the refrigerator in the preferred embodiment of the invention is suitable for the refrigerator provided with the ice machine, and the ice machine at least comprises an ice making grid, a water injection module and an ice making module. The refrigerator is internally provided with a main control module, and the water injection module and the ice making module are electrically connected with the main control module.
In a practical arrangement, the ice maker may be provided in a separate ice making chamber. The water injection module can be a water injection pipe, and the water injection amount is controlled through a water valve. The ice making module can be a refrigerant pipe which directly provides cold energy for the ice making grid and controls the ice making process by controlling the supply of valve control cold energy; or an air duct for providing cold air for the ice making grids controls the air volume of the cold air through the air duct so as to control the ice making process.
Referring to fig. 1, the control method of the refrigerator mainly includes the steps of:
s1, presetting total water injection time length T required by a water injection module to fill water into an ice cube tray in a main control module; the water injection time of each water injection module is T, T = n x T, and n is a natural number greater than or equal to 2; the wait time after stopping the water injection is Tt.
And S2, the main control module acquires an ice making starting instruction. The user can input an ice making starting instruction through a control panel of the refrigerator, or input the ice making starting instruction through mobile terminal equipment such as a mobile phone and the like which are in communication connection with the main control module.
S3, executing a water injection step: the main control module controls the water injection module to start injecting water to the ice cube tray, when the water injection duration reaches t, the water injection is stopped, and the main control module records the water injection duration t.
S4, executing an ice making step: the main control module controls the ice making module to start making ice until the water filled into the ice making cells freezes, and the ice making is stopped.
S5, the main control module judges whether the total sum of the water injection time length T is equal to the total water injection time length T or not according to the T obtained through recording, if not, the water is not filled, the water injection step S3 and the ice making step S4 are sequentially executed for one time, and then whether the total sum of the T is equal to the T or not is judged; if yes, the water is filled, ice making is finished, and ice making is finished.
After ice making is finished, the ice blocks in the ice making grids can be turned out to the ice storage box through the ice turning mechanism. Furthermore, a detection mechanism for detecting whether the ice storage box is full of ice can be further arranged, and when the ice storage box is detected to be full of ice, ice making is not started even if the main control module receives an ice making starting instruction.
According to the control method of the refrigerator, water is injected into the ice making grids for multiple times to make ice by controlling the water injection module and the ice making module to work at intervals. Because the water volume injected each time is less than the total water volume, compared with the mode of filling water in one time in the prior art, the method has the advantages that the bubbles generated in the water injection process are less, the water volume is less, the air can overflow from the water quickly, and the bubbles in the ice layer produced each time are less. The mode of dividing water injection many times and making ice many times that this application provided has greatly improved the many problems of the inside bubble of ice-cube, makes the inside bubble of the ice-cube that finally makes reduce, and the ice-cube compactness improves, effectively improves user experience.
In some embodiments of the present application, referring to fig. 2, before performing the ice making step S4, a waiting step S30 is further performed. The execution waiting step S30 is: the waiting time Tt after stopping the water injection reaches a first preset time, wherein the first preset time can be 1-20min, and preferably 5-12min. The waiting time is increased after water injection and before ice making, which is favorable for more air to overflow and further reduces bubbles in water, and the waiting time can be set according to the water injection amount each time and the ice making time expected by a customer.
In some embodiments of the present disclosure, it may be determined whether the ice is frozen or not by the duration of the activation of the ice making module. Specifically, in the ice making step S4, after the ice making module starts making ice, the duration of the start of the ice making module is recorded, and when the duration reaches a second preset time, it is determined that the injected water is frozen. Wherein the second predetermined time is 30-90min, preferably 40-60min.
In some embodiments of the present application, a temperature sensor electrically connected to the main control module may be disposed in the ice maker, and configured to detect the temperature of the water injected at the current time in real time, and determine whether the water injected at the current time is frozen according to the temperature. Specifically, in the ice making step S4, after the ice making module starts making ice, the temperature sensor detects the temperature of the last injected water in real time. In practical application, different conditions can be set according to the temperature value detected by the temperature sensor so as to judge whether the water injected at the time is frozen or not. For example, it may be set to judge that the freezing of the injected water is completed when the temperature is less than-2 ℃ for a third preset time. Wherein the third predetermined time period may be 10-40min, preferably 20-30min. Or, the temperature can be set to be less than-4 ℃, and the injected water is judged to be frozen completely.
In actual use, there may be a case where the user stops ice making halfway before the end of ice making. And when the main control module obtains an ice making stop instruction before finishing ice making and executes the water injection step S3, controlling the water injection module to continue injecting water until the water injection time reaches t, stopping injecting water, namely finishing water injection after water injection, recording the sum of the water injection time t, and finishing ice making. In this case, when the ice-making start instruction is newly acquired, the ice-making step is first executed to re-freeze the injected water into ice. Then judging whether the sum of the water injection time lengths T is equal to the total water injection time length T or not, if not, namely the water is not filled, sequentially executing a water injection step S3 and an ice making step S4, or sequentially executing a water injection step S3, a waiting step S30 and an ice making step S4; if so, the water is filled, the ice making step S4 is executed, and the ice making is finished.
According to the control method of the refrigerator, the application provides a specific embodiment as follows:
s1a, presetting total water injection time length required by a water injection module to fill water into an ice making grid to be T, dividing the total water injection time length into 3 times of water injection, wherein the water injection time length of each time of the water injection module is T1, T2 and T3, (T1 + T2+ T3) = T; the wait times after stopping the water injection are Tt1 and Tt2. That is, in one ice making process, the ice cube tray is filled with water 3 times.
S2a, acquiring an ice making starting instruction;
s3a, executing a water injection step: controlling a water injection module to start injecting water into the ice cube tray, and stopping injecting water when the water injection time length reaches t1;
s30a, executing a waiting step: waiting for Tt1 after stopping water injection;
s4a, executing an ice making step: controlling the ice making module to start making ice until the water filled into the ice making cells is frozen, and stopping making ice;
s5a, judging to obtain that the water injection time T1 is less than the total water injection time T;
continuing to sequentially execute the water injection step, the waiting step and the ice making step, namely continuing to control the water injection module to inject water into the ice making grids, stopping injecting water when the water injection time length t2 is reached, and controlling the ice making module to start ice making after the waiting time reaches Tt1 until the water injected into the ice making grids is frozen, and stopping ice making;
judging that the obtained water injection time length (T1 + T2) is less than the total water injection time length T;
continuing to sequentially execute the water injection step, the waiting step and the ice making step, namely continuing to control the water injection module to inject water into the ice making grid, stopping injecting water after the water injection duration t3 is reached, and controlling the ice making module to start ice making until the injected water is frozen after the waiting time reaches Tt 2;
and judging that the water injection time length (T1 + T2+ T3) is equal to the total water injection time length T, and finishing ice making.

The processor and the memory can be integrated into a main control module of the refrigerator.
In summary, the refrigerator and the control method of the refrigerator provided by the embodiment of the invention realize water injection and ice making for the ice making grids for multiple times by controlling the water injection module and the ice making module to work at intervals. Because the water volume of each time of injection all is less than total water volume, consequently compare the mode of filling up water at one time of prior art, the bubble that produces in the water injection process of each time is also less, and the water volume is few moreover does benefit to the air and spills over from the water fast, makes the intraformational bubble of ice of making each time all few. The mode of dividing water injection many times and making ice many times that this application provided has greatly improved the many problems of the inside bubble of ice-cube, makes the inside bubble of the ice-cube that finally makes reduce, and the ice-cube compactness improves, effectively improves user experience.
In another inventive concept, increasing the waiting time after filling water and before making ice may facilitate more air overflow and further reduce bubbles in the water, and the waiting time may be set according to the amount of water filled each time and the ice making time expected by the customer.
In another inventive concept, aiming at the condition that the user stops ice making midway, the control is finished, the water injection is stopped after the water injection is finished, the sum of the water injection time lengths T is recorded, then the ice making is finished, after the ice making starting instruction is obtained again, whether the sum of the water injection time lengths T accumulated at the previous time is equal to the total water injection time length T or not is judged, and then different steps are correspondingly executed according to the judgment result.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
