Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes a refrigeration device and a defrosting control method and device thereof according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for controlling defrosting of a refrigeration apparatus according to an embodiment of the present invention. As shown in fig. 1, the method for controlling defrosting of a refrigeration device according to an embodiment of the present invention includes the following steps:
s101: detecting and identifying that the ice making compartment reaches a defrosting condition, and controlling the ice making compartment and the freezing compartment to defrost.
S102: detecting and identifying that the defrosting of the ice making compartment is finished, and controlling the ice making compartment and the freezing compartment to finish defrosting.
That is, the present application proposes a method of controlling both an ice making compartment and a freezing compartment to simultaneously defrost when the ice making compartment reaches a defrosting condition, and controlling both the ice making compartment and the freezing compartment to simultaneously finish defrosting when the ice making compartment reaches a finishing defrosting condition, so that both the ice making compartment and the freezing compartment can be subjected to defrosting operation, and also an ice making effect of the ice making compartment is ensured.
Further, before controlling the ice making compartment and the freezing compartment to finish defrosting, as shown in fig. 2, the method further comprises:
s201: a first sensed temperature of a condenser corresponding to the freezer compartment is obtained.
S202: the first detected temperature is identified as being greater than or equal to a first temperature threshold.
Wherein the first temperature threshold may be 0 DEG C
That is, before the defrosting of the ice making compartment is completed, the first detection temperature of the condenser corresponding to the freezing compartment, that is, the temperature of the defrosting sensor of the freezing compartment needs to be detected before the defrosting of the ice making compartment and the freezing compartment is completed, if the first detection temperature is greater than or equal to the first temperature threshold, the condition that the defrosting operation is exited is indicated to be currently satisfied by the freezing compartment, and the defrosting of the ice making compartment and the freezing compartment is completed can be controlled, otherwise, if the first detection temperature is less than the first temperature threshold, the condition that the defrosting operation is exited is indicated to be not satisfied currently by the freezing compartment, and the defrosting of the ice making compartment and the freezing compartment needs to be continuously controlled until the condition that the defrosting of the ice making compartment is completed is satisfied, and the condition that the first detection temperature is greater than or equal to the first temperature threshold is satisfied.
It should be understood that the first detected temperature being greater than or equal to the first temperature threshold is a condition that the freezing compartment can exit the defrosting operation, and is not a condition that the freezing compartment completes defrosting, in other words, when the first detected temperature is greater than or equal to the first temperature threshold, the freezing compartment exits the defrosting operation and can continue to refrigerate, although the frosting phenomenon can occur in the refrigeration process, but the use and the refrigeration effect are not affected.
Based on this, according to one embodiment of the present invention, further comprising: and identifying that defrosting of the freezing compartment is not finished according to the first detection temperature.
Specifically, it is identified that the first detected temperature is less than the second temperature threshold.
That is, the first detected temperature of the condenser corresponding to the freezing compartment may be divided into a plurality of stages, and if the first detected temperature is less than the first temperature threshold, it means that the freezing compartment is currently unable to exit the defrosting operation, and if the first detected temperature is increased to be greater than or equal to the first temperature threshold and less than the second temperature threshold, it means that the defrosting operation is still possible although the defrosting operation is not completed, and if the first detected temperature is greater than the second temperature threshold, it means that the defrosting operation of the freezing compartment is completed.
Further, in case that the defrosting of the freezing compartment is not completed, controlling the ice making compartment and the freezing compartment to finish defrosting, as shown in fig. 3, further includes:
s301: the number of outstanding frostings of the freezer compartment is updated.
S302: and identifying that the number of times of incomplete defrosting reaches a preset number of times.
S303: and controlling the freezing compartment to carry out additional defrosting.
That is, when the ice making compartment finishes defrosting and the freezing compartment does not finish defrosting but the first detected temperature is greater than or equal to the first temperature threshold, controlling the ice making compartment and the freezing compartment to finish defrosting and updating the number of times of the incomplete defrosting of the current freezing compartment, if the updated number of times of the incomplete defrosting reaches a preset number of times, indicating that the freezing compartment needs to be additionally defrosted to ensure safe operation, and if the updated number of times of the incomplete defrosting does not reach the preset number of times, controlling the freezing compartment and the ice making compartment to perform refrigeration operation and performing defrosting operation again when the ice making compartment reaches a defrosting condition.
It should be understood that the ice-making compartment is controlled to perform a cooling operation during additional defrosting of the freezing compartment, in other words, the ice-making compartment is not defrosted when additional defrosting of the freezing compartment is performed, and the ice-making compartment is controlled to maintain a cooling state.
Further, before controlling the freezing compartment to perform additional defrosting, the method further comprises: detecting and identifying that the duration of the refrigerating operation of the ice making compartment reaches a first preset duration.
It should be understood that before additional defrosting, the ice making compartment and the freezing compartment are simultaneously in a refrigerating operation state, and at this time, the duration of the refrigerating operation of the ice making compartment is detected and identified to reach a first preset duration, which indicates that the refrigerating operation of the first preset duration is required before the additional defrosting of the freezing compartment is controlled, so as to prevent the ice making effect of the ice making compartment from being affected by the defrosting operation of the freezing compartment, thereby improving the ice storage temperature and ice storage quality of the ice making compartment.
Similarly, it may also be detected and identified that the current temperature within the ice making compartment is less than or equal to a third temperature threshold.
According to an embodiment of the present invention, as shown in fig. 4, after controlling the freezing compartment to perform additional defrosting, the method further comprises:
s401: and obtaining the running time of additional defrosting of the freezing compartment.
S402: and identifying that the running time is greater than or equal to the second preset time.
S403: and controlling the freezing compartment to finish defrosting.
That is, the freezing compartment can be controlled to exit the defrosting operation according to the defrosting time of the additional defrosting of the freezing compartment.
Specifically, after the additional defrosting of the freezing compartment is started, the running time of the additional defrosting of the freezing compartment is obtained in real time, then whether the running time is larger than or equal to a second preset time is judged, if the running time is larger than or equal to the second preset time, the freezing compartment is controlled to achieve the exit condition of the additional defrosting, if the running time is smaller than the second preset time, the freezing compartment is controlled to achieve the exit condition of the additional defrosting, and if the running time is smaller than the second preset time, the freezing compartment is controlled to continue defrosting until the running time is larger than or equal to the second preset time.
Similarly, the second detected temperature of the condenser corresponding to the freezing compartment may also be used as an exit condition for additional defrosting of the freezing compartment.
In one embodiment, as shown in fig. 5, after controlling the freezing compartment to perform additional defrosting, the method further comprises:
s501: and obtaining a second detection temperature of the condenser corresponding to each freezing compartment.
S502: and identifying that the second detection temperature is greater than or equal to a defrosting end temperature threshold corresponding to the freezing compartment for each freezing compartment, and controlling the freezing compartment to end defrosting.
In another embodiment, as shown in fig. 6, after controlling the freezing compartment to perform additional defrosting, the method further comprises:
s601: a second sensed temperature of each freezer compartment defrosting sensor is obtained.
S602: and identifying that the second detection temperature is greater than or equal to a defrosting end temperature threshold value for each freezing compartment, and controlling the freezing compartment to end defrosting.
Further, the number of the freezing compartments with the second detection temperature being larger than or equal to the defrosting end temperature threshold value is obtained, the number is identified to reach the preset number, and the rest freezing compartments are controlled to finish defrosting.
That is, when the refrigerating apparatus has a plurality of refrigerating compartments, after the plurality of refrigerating compartments perform the additional defrosting operation, the second detection temperature of the condenser corresponding to each refrigerating compartment is obtained in real time, whether the defrosting end temperature threshold is reached is judged according to the second detection temperature, and when the second detection temperature is greater than or equal to the defrosting end temperature threshold, the refrigerating compartments are controlled to end defrosting, and then when Su Liang of the refrigerating compartments ending defrosting reaches a preset number, all the refrigerating compartments are controlled to end defrosting.
It will be appreciated that the defrosting end temperature thresholds for the different freezer compartments may be the same or may be different, e.g. 2 ℃, 4 ℃ or-1 ℃, due to the fact that the roles of the individual freezer compartments may be different, e.g. frozen deli, frozen deli etc. When the frost formation end temperature thresholds of the respective freezing compartments are different, the control method shown in fig. 5 may be used to control the exit of the frost formation of the freezing compartments, and when the frost formation end temperature thresholds of the respective freezing compartments are the same, the control method shown in fig. 6 may be used to control the exit of the frost formation of the freezing compartments.
In summary, according to the control method for defrosting a refrigerator of the embodiment of the invention, by detecting the defrosting condition of the ice making compartment, controlling the ice making compartment and the freezing compartment to defrost simultaneously when the ice making compartment reaches the defrosting condition, and controlling the ice making compartment and the freezing compartment to finish defrosting simultaneously when the ice making compartment reaches the finish defrosting condition, both the ice making compartment and the freezing compartment can be subjected to defrosting operation, and the ice making effect of the ice making compartment is ensured. Meanwhile, when the number of times of not completing defrosting of the freezing compartment reaches the preset number of times, defrosting is added to the freezing compartment, so that the defrosting effect of the freezing compartment is further ensured.
In order to realize the embodiment, the invention also provides a defrosting control device of the refrigeration equipment.
