And if the defrosting stage is not in the defrosting stage before the quick-freezing function is started, immediately entering a defrosting period, and starting the quick-freezing function and starting timing after defrosting is finished. And if the defrosting process is carried out before the quick-freezing function is started, defrosting is continued after the quick-freezing function is started, the quick-freezing function icon is kept on, and after defrosting is finished, quick-freezing operation is started and timing is started.
If the refrigerator is powered off in the defrosting operation stage of the quick-freezing stage after entering the quick-freezing function, the refrigerator continues to complete defrosting operation until the refrigerator exits the defrosting operation and enters the quick-freezing operation because the refrigerator is in the defrosting stage at the moment after the power is cut off and the power is re-powered on.
Therefore, the refrigerator firstly checks whether the refrigerator is in a defrosting period after the quick-freezing function is started, and if the refrigerator is in the defrosting period, defrosting is continued; if the defrosting cycle is not in the defrosting cycle, starting the quick-freezing function after the defrosting cycle is finished; defrosting is carried out before quick freezing, so that the refrigerator can run a quick freezing function in the best state, and the freezing capacity is improved.

In some embodiments, further comprising: the process of exiting the quick-freezing mode after the quick-freezing function is started comprises any one of the following situations of exiting the quick-freezing mode.
The first case of exiting the snap mode: and under the condition that the refrigerator runs in a set speed mode and is not powered off, if the running time of the refrigerator in the quick-freezing mode reaches set time, exiting the quick-freezing mode.
Specifically, in the process of quick-freezing operation, if the refrigerator is not powered off, the refrigerator continuously operates under the quick-freezing function for a quick-freezing set time and then quits, so that the freezing effect is ensured, and the energy is saved.
The second case of exiting the snap mode: and under the condition that the refrigerator runs in a set speed mode and is powered off, after the refrigerator is powered on again, the running time of the refrigerator in the quick-freezing mode is re-timed, and if the running time of the refrigerator in the quick-freezing mode reaches the set time, the refrigerator is quitted from the quick-freezing mode.

After power is cut off, the power is supplied again, and the number of starting and stopping points of the freezing chamber can be any number; after the power is cut off, the power is supplied again, and the quick-freezing duration can be reset without keeping consistent with that before the power is cut off. After the quick-freezing function is started, the power-off condition of the refrigerator has two processing modes: one is that the refrigerator is powered off in a defrosting stage, the other is that the refrigerator is powered off in a quick-freezing function operation stage, and the refrigerator continues to operate before being powered off again until an exit condition is met.
Therefore, the method that power-off memory is carried out after quick freezing is started, whether the maximum quick freezing time is reached or a stop point is reached is judged again after power-on, and the exit condition of 3 or more start-stop periods is operated is adopted, so that the problem that the quick freezing function exits due to power-off and the freezing chamber of the refrigerator cannot reach the set temperature is solved, and the user experience is improved; the problem that the quick-freezing operation time of the refrigerator is too long because the quick-freezing function is quitted due to power failure and timing is restarted after the refrigerator is powered on again is solved, so that the energy consumption is reduced; the problem that the refrigerator cannot reach the set quick-freezing temperature due to the fact that the continuous operation time of the quick-freezing is short due to power failure and the refrigerator continues to count again after being electrified is solved, and therefore user experience is improved.
In some embodiments, further comprising: the control process after the quick-freezing mode exits specifically comprises the following steps: and after the quick-freezing mode is exited, controlling the refrigerator to operate according to the operation mode before the quick-freezing mode is entered.

The specific function and processing of the control unit are also referred to in step S130.
Specifically, after the refrigerator enters the quick-freezing function, the icon of the quick-freezing function is kept on, and the defrosting stage is started. And if the defrosting stage is not in the defrosting stage before the quick-freezing function is started, immediately entering a defrosting period, and starting the quick-freezing function and starting timing after defrosting is finished. And if the defrosting process is carried out before the quick-freezing function is started, defrosting is continued after the quick-freezing function is started, the quick-freezing function icon is kept on, and after defrosting is finished, quick-freezing operation is started and timing is started.
If the refrigerator is powered off in the defrosting operation stage of the quick-freezing stage after entering the quick-freezing function, the refrigerator continues to complete defrosting operation until the refrigerator exits the defrosting operation and enters the quick-freezing operation because the refrigerator is in the defrosting stage at the moment after the power is cut off and the power is re-powered on.
Therefore, the refrigerator firstly checks whether the refrigerator is in a defrosting period after the quick-freezing function is started, and if the refrigerator is in the defrosting period, defrosting is continued; if the defrosting cycle is not in the defrosting cycle, starting the quick-freezing function after the defrosting cycle is finished; defrosting is carried out before quick freezing, so that the refrigerator operates a quick freezing function in the best state, and the freezing capacity is improved; the device for defrosting is adopted after the quick-freezing function is set, so that the problem that the freezing capacity is reduced to some extent due to thick frosting of the evaporator of the refrigerator is solved, and the freezing capacity of the refrigerator is improved.

The third case of exiting the snap mode: the control unit is further configured to exit the quick-freeze mode if the temperature of the freezing compartment of the refrigerator reaches a set temperature and the compressor of the refrigerator has undergone a set number of start-stop cycles after the refrigerator is powered up again when the refrigerator is operated in a set speed mode and powered off.
Specifically, in the quick-freezing operation process, if the refrigerator is not powered off, the refrigerator continuously operates under the quick-freezing function for a quick-freezing set time and then quits; if the power is cut off and the power is supplied again, the refrigerator continuously runs for 24 hours under the quick-freezing function and then is taken out; or, if the power is cut off and the power is supplied again, the freezing chamber of the refrigerator reaches the stop point, and the refrigerator is exited after running for 3 or more start-stop periods. After power is cut off, the power is supplied again, and the number of starting and stopping points of the freezing chamber can be any number; after the power is cut off, the power is supplied again, and the quick-freezing duration can be reset without keeping consistent with that before the power is cut off. After the quick-freezing function is started, the power-off condition of the refrigerator has two processing modes: one is that the refrigerator is powered off in a defrosting stage, the other is that the refrigerator is powered off in a quick-freezing function operation stage, and the refrigerator continues to operate before being powered off again until an exit condition is met.
Therefore, the device adopts power-off memory after entering quick freezing, judges whether the maximum time of quick freezing is reached or a stop point is reached again after power-on, and operates 3 or more than 3 start-stop cycle exit conditions, so that the problem that the quick freezing function exits due to power-off and the freezing chamber of the refrigerator cannot reach a set temperature is solved, and the user experience is improved; the problem that the quick-freezing operation time of the refrigerator is too long because the quick-freezing function is quitted due to power failure and timing is restarted after the refrigerator is powered on again is solved, so that the energy consumption is reduced; the problem that the refrigerator cannot reach the set quick-freezing temperature due to the fact that the continuous operation time of the quick-freezing is short due to power failure and the refrigerator continues to count again after being electrified is solved, and therefore user experience is improved.

The quick-freezing process is interrupted, electricity is electrified again to perform quick-freezing without quitting, the quick-freezing time is continuously timed, and the temperature of the freezing chamber of the refrigerator cannot reach the set temperature, so that the user experience is poor.
For example: before power failure, the quick-freezing function is in operation, and after the power is turned on again, the quick-freezing function is quitted.
For example: before power failure, the quick-freezing function is in operation, and after the power is turned on again, the quick-freezing function is timed again.
In some embodiments, the scheme of the invention provides a refrigerator quick-freezing control method, wherein after a quick-freezing function of a refrigerator is started, whether the refrigerator is in a defrosting period is checked, and if the refrigerator is in the defrosting period, defrosting is continued; if the defrosting cycle is not in the defrosting cycle, the quick-freezing function is started after the defrosting cycle is finished. Thus, defrosting is performed before quick freezing, so that the refrigerator operates a quick freezing function in the best state, and the freezing capacity is improved. That is, a method of defrosting after setting a quick-freezing function is adopted, so that the problem that the freezing capacity is reduced due to thick frosting of an evaporator of the refrigerator is solved, and the freezing capacity of the refrigerator is improved.
According to the scheme of the invention, in the quick-freezing operation process, if the refrigerator is not powered off, the refrigerator continuously operates under the quick-freezing function for a quick-freezing set time and then quits; if the power is cut off and the power is supplied again, the quick-freezing function is quitted under the following condition:
a. and powering up again after power failure, and continuously running the refrigerator for 24 hours under the quick-freezing function and then withdrawing the refrigerator.
b. And powering off and powering on again, wherein the freezing chamber of the refrigerator reaches a stop point, and exits after running for 3 or more start-stop periods.
Therefore, the method that power-off memory is carried out after quick freezing is started, whether the maximum quick freezing time is reached or a stop point is reached is judged again after power-on, and the exit condition of 3 or more start-stop periods is operated is adopted, so that the problem that the quick freezing function exits due to power-off and the freezing chamber of the refrigerator cannot reach the set temperature is solved, and the user experience is improved; the problem that the quick-freezing operation time of the refrigerator is too long because the quick-freezing function is quitted due to power failure and timing is restarted after the refrigerator is powered on again is solved, so that the energy consumption is reduced; the problem that the refrigerator cannot reach the set quick-freezing temperature due to the fact that the continuous operation time of the quick-freezing is short due to power failure and the refrigerator continues to count again after being electrified is solved, and therefore user experience is improved.

step 1, after the refrigerator enters the quick-freezing function, keeping the quick-freezing function icon on, and entering a defrosting stage.
And if the defrosting stage is not in the defrosting stage before the quick-freezing function is started, immediately entering a defrosting period, and starting the quick-freezing function and starting timing after defrosting is finished.
And if the defrosting process is carried out before the quick-freezing function is started, defrosting is continued after the quick-freezing function is started, the quick-freezing function icon is kept on, and after defrosting is finished, quick-freezing operation is started and timing is started.
If the refrigerator is powered off in the defrosting operation stage of the quick-freezing stage after entering the quick-freezing function, the refrigerator continues to complete defrosting operation until the refrigerator exits the defrosting operation and enters the quick-freezing operation because the refrigerator is in the defrosting stage at the moment after the power is cut off and the power is re-powered on.
Step 2, after the quick-freezing operation is carried out, the compressor and the freezing and evaporating fan operate at the highest rotating speed, and the temperature of the freezing chamber is set to be the lowest temperature which can be set in the chamber, such as TQuick-freezing mode freezing set temperatureUnder the condition of no power failure, the refrigerator runs for setting the quick-freezing time t DEG C after the quick-freezing function begins to be timedTime of quick freezingSuch as 24h exit.
And 3, if the refrigerator is powered off in the running process of the quick-freezing function, the refrigerator is still in a quick-freezing state after being powered on, and the quick-freezing exit condition is changed into (one of the conditions is satisfied):
after the power is cut off and the power is re-electrified, the quick-freezing function is re-timed, and the quick-freezing function is withdrawn when the accumulated running time reaches 24 hours.
And secondly, after the power is cut off and the refrigerator is electrified again, when the freezing chamber of the refrigerator reaches the set temperature, the compressor is subjected to three or more complete start-stop periods, and the refrigerator quits the quick-freezing function.
The set temperature here is the set temperature of the freezing chamber in the quick-freezing function, for example, the freezing chamber in the quick-freezing function is generally-26 ℃, and the set temperature is-26 ℃ at this time, and is not the lowest temperature that can be set.
On-off period of the compressor: the starting and stopping of the compressor are a starting and stopping period, and the like.
After the power is cut off, the power is supplied again, and the number of starting and stopping points of the freezing chamber can be any number; after the power is cut off, the power is supplied again, and the quick-freezing duration can be reset without keeping consistent with that before the power is cut off.
And 4, after the refrigerator exits the quick-freezing function, the freezing chamber is controlled according to the set temperature before entering the quick-freezing, other chambers are not affected, the control is continued according to the original function or temperature, and the compressor and the freezing fan are also controlled according to the rotating speed under the normal working condition, so that the energy consumption of the refrigerator is saved.
For example: the temperature of the freezing chamber before entering the quick freezing is minus 18 ℃, and the temperature of the freezing chamber is still minus 18 ℃ after the quick freezing is quitted.
In the control method of the invention, after the quick-freezing function is started, the power-off condition of the refrigerator has two processing modes: one is that the refrigerator is powered off in a defrosting stage, the other is that the refrigerator is powered off in a quick-freezing function operation stage, and the refrigerator continues to operate before being powered off again until an exit condition is met.
