In addition, the invention also provides a quick-freezing control method of the refrigerator, wherein the method is used for controlling the refrigerator, and the specific structure of the refrigerator can be seen in fig. 1 to 3.
Referring to fig. 4, in a first embodiment of a quick-freeze control method of a refrigerator provided by the present invention, the quick-freeze control method of the refrigerator includes the following steps:
step S10, receiving a quick-freezing control instruction, and entering a quick-freezing mode;
specifically, the refrigerator may be started up as the quick-freezing control instruction is issued, or the user may press the quick-freezing key to enter the quick-freezing mode after putting the food into the quick-freezing device 5.
Step S20, adjusting the frequency of the compressor, the rotating speed of the fan and the input voltage of the semiconductor refrigeration module to reduce the load temperature of the quick freezing device of the refrigerator;
specifically, the refrigerator may be started up and operated, that is, the refrigerator enters the quick-freezing mode, so that the frequency of the compressor may be directly adjusted to the operating frequency of the refrigerator in the quick-freezing mode, the rotation speed of the fan 7 may be adjusted to the operating rotation speed of the refrigerator in the quick-freezing mode, and the input voltage of the semiconductor refrigeration module 52 may be adjusted to the driving voltage of the refrigerator in the quick-freezing mode; meanwhile, when the refrigerator operates in the freezing mode, a user presses a freezing key, so that the frequency of the compressor needs to be increased from the operating frequency in the freezing mode to the operating frequency in the quick-freezing mode, the rotating speed of the fan 7 is increased from the operating rotating speed in the freezing mode to the operating rotating speed in the quick-freezing mode, and the input voltage of the semiconductor refrigerating module 52 is increased from zero voltage or low voltage to the driving voltage in the freezing mode. In addition, the control of the rotating speed of the fan 7 can be realized by adjusting the duty ratio of the fan 7, and the input voltage of the semiconductor refrigeration module 52 in the quick-freezing mode can be the rated voltage of the semiconductor refrigeration module 52.
Step S30, obtaining the load temperature of the quick-freezing device;
in the present invention, the quick-freezing device 5 may be provided with the temperature sensor 54, so that the load temperature of the quick-freezing device 5 can be detected in real time by the temperature sensor 54. Of course, the present invention is not limited to this, and the temperature sensor 54 may not be directly disposed on the quick-freezing device 5, and may indirectly obtain the load temperature of the quick-freezing device 5 through a related algorithm.
Step S40, judging whether the load temperature reaches a preset quick-freezing temperature;
in the present invention, the minimum value of the load temperature reached by the quick-freezing device 5 in the quick-freezing mode may be set, and the minimum value may be set as the preset quick-freezing temperature, and the load temperature of the quick-freezing device 5 detected by the temperature sensor 54 is compared with the preset quick-freezing temperature to determine whether the load temperature reaches the preset quick-freezing temperature. In addition, the preset quick freezing temperature includes, but is not limited to, at-35 ℃ or-40 ℃.
And step S50, if the load temperature does not reach the preset quick-freezing temperature, the quick-freezing mode is exited.
In this embodiment, through the frequency of adjusting the compressor, the rotational speed of fan 7 and the input voltage of semiconductor refrigeration module 52 in order to get into the quick-freeze mode of refrigerator to make quick-freezing device 5 superpose the cold source of freezing room itself and the cold source that semiconductor refrigeration module 52's cold junction provided, thereby make the temperature of quick-freezing device 5 lower than the indoor temperature of traditional freezing room, can avoid appearing eating the phenomenon that material air-dries and taste worsened. In addition, whether the quick-freezing mode is exited or not is determined by judging whether the load temperature of the quick-freezing device 5 reaches the preset quick-freezing temperature or not, so that the loss of the energy consumption of the refrigerator can be reduced on the premise of ensuring the quick-freezing effect.
Further, referring to fig. 5, a second embodiment of the quick-freeze control method of the refrigerator is provided according to the first embodiment of the quick-freeze control method of the refrigerator provided by the present invention, in this embodiment, the step S30 includes:
step S60, judging whether the quick-freezing time of the refrigerator entering the quick-freezing mode is in a preset quick-freezing period, wherein the preset quick-freezing period is a time period which is greater than a first time threshold and less than a second time threshold;
specifically, the preset quick-freezing period may be a time period greater than the first time threshold and less than the second time threshold, that is, whether the quick-freezing time of the refrigerator entering the quick-freezing mode is in the preset quick-freezing period may be monitored, so as to avoid that the quick-freezing time of the refrigerator entering the quick-freezing mode is too short to cause a poor quick-freezing effect or too long to cause energy loss. Further, in the present invention, the first time threshold includes, but is not limited to, taking 30min, and the second time threshold includes, but is not limited to, taking 8 h.
And step S70, if the quick-freezing time is in the preset quick-freezing period, detecting the load temperature of the quick-freezing device.
In the embodiment, the load temperature of the quick-freezing device 5 is detected only when the quick-freezing time when the refrigerator enters the quick-freezing mode satisfies the preset quick-freezing period between the first time threshold and the second time threshold, so that the time period for detecting the load temperature of the quick-freezing device 5 by the temperature sensor 54 can be reduced, and the energy consumption loss is reduced. In addition, the minimum time threshold and the maximum time threshold are limited for the quick-freezing time of the refrigerator entering the quick-freezing mode, so that the phenomenon that the quick-freezing effect is poor or the energy consumption is lost due to the overlong quick-freezing time of the refrigerator entering the quick-freezing mode can be avoided.
Further, according to a second embodiment of the quick-freeze control method of the refrigerator provided by the present invention, a third embodiment of the quick-freeze control method of the refrigerator is provided, in this embodiment, after step S60, the method further includes:
step S80, if the quick-freezing time is not in the preset quick-freezing period, judging whether the quick-freezing time is greater than or equal to the second time threshold;
and step S90, if the quick-freezing time is greater than or equal to the second time threshold, controlling the refrigerator to exit the quick-freezing mode.
In this embodiment, when the quick-freezing time of the refrigerator entering the quick-freezing mode is not within the preset quick-freezing period between the first time threshold and the second time threshold, the quick-freezing time may be continuously compared with the second time threshold, and if the quick-freezing time is greater than or equal to the second time threshold, the refrigerator is controlled to exit the quick-freezing mode.
