FIG. 1 is a flow chart of an embodiment of the present invention;
FIG. 2 is a control logic diagram according to an embodiment of the present invention.
Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The principles and construction of the present invention will be described in detail below with reference to the drawings and examples.
As shown in fig. 1 and 2, the present invention provides a method for controlling a refrigeration storage device, which is specifically a refrigerator, and may also be other refrigeration storage devices having a freezing compartment and a refrigerating compartment, the method specifically includes the steps of: after the equipment normally operates for a period of time, the temperature of the freezing chamber of the refrigeration storage equipment is monitored, whether the temperature exceeds an abnormal value or not is judged, and if yes, the quick-freezing control logic is switched to carry out quick cooling on the freezing chamber and reduce the cold supply of the refrigerating chamber. If not, the operation is continued according to the normal control logic. In the single-system refrigerator, when a user puts a large amount of normal-temperature food into a freezing chamber and needs quick freezing, the control logic can be adopted to automatically judge the refrigerator according to whether the temperature exceeds an abnormal value or not, the control logic is automatically switched into the quick-freezing control logic, the user does not need to set the control logic by himself, the quick-freezing control logic can not only increase the refrigerating capacity, but also reduce the cold supply of other chambers, and the freezing speed and the freezing capacity are improved.
In a specific embodiment, the obtaining of the outlier comprises the steps of: the method comprises the steps of obtaining temperature values of a plurality of time nodes in the operation of the freezing chamber, fitting the distribution of the temperature values into normal distribution, calculating the average temperature value mu and the standard deviation sigma in the normal operation of the freezing chamber according to the normal distribution, wherein the abnormal value is mu + k sigma, and the value range of k is [1,3 ]. In a specific experiment, the probability of the temperature distribution within (μ -3 σ, μ +3 σ) was 99.73% according to the normal distribution. Since the probability of a temperature higher than μ +3 σ is only 0.18%, T > μ +3 σ can be treated as an outlier, i.e., the outlier is preferably μ +3 σ. k can be set to other values according to actual conditions, so that the detection sensitivity is improved.
And after the gear of the freezing chamber is switched, re-acquiring the temperature values of a plurality of time nodes in the operation of the freezing chamber, and fitting the distribution of the re-acquired temperature values into normal distribution to update the abnormal values.
In one embodiment, to avoid outliers are triggered by other reasons, rather than because the user is heavily conditioned. Therefore, before the quick-freezing control logic is switched to quickly cool the freezing compartment, whether the freezing gear of the refrigerator changes within the preset time is judged, if yes, the refrigerator continues to operate according to the normal control logic, and if not, the next judgment step is executed or the quick-freezing control logic is switched to quickly cool the freezing compartment. Because the refrigerating capacity of the refrigerating chamber changes after a period of time after the gear changes, and the temperature also changes, the control directly according to the abnormal value conflicts with the original logic.
The following judgment steps are executed: and judging whether the door of the freezing chamber is opened overtime or not or whether door opening alarm occurs or not, if so, continuing to operate according to normal control logic, and if not, executing the step of switching to quick-freezing control logic to carry out quick cooling on the freezing chamber. Because the user generally forgets to close the door or the door is not closed tightly when the compartment door is opened overtime, a large amount of cold energy can be lost, and only the loss of the cold energy can be increased by performing quick refrigeration at the moment.
In another embodiment, before the quick-freezing control logic is switched to quickly cool the freezing chamber, whether the door of the freezing chamber is opened overtime is judged, if yes, the door is continuously operated according to the normal control logic, and if not, the step of switching to the quick-freezing control logic to quickly cool the freezing chamber is executed.
The normal control logic is: the rotating speed of the compressor is a preset rotating speed S0, the rotating speed of the fan is a preset rotating speed F0, and the temperature of the starting point and the stopping point of the refrigerating chamber is T0.
The quick-freezing control logic is as follows: the rotating speed of the compressor is increased to a preset rotating speed S1, the rotating speed of the fan corresponding to the freezing chamber is increased to a preset rotating speed F1, the temperature of the starting and stopping point of the refrigerating chamber of the refrigerator is increased to T1, and the opening frequency and/or the opening time of the air door of the refrigerating chamber are/is reduced.
The invention also provides a refrigeration storage device, which avoids the temperature abnormality of the freezing chamber by using the control method. The refrigeration storage equipment can be a refrigerator, and also can be other refrigeration storage equipment with a freezing chamber and a refrigerating chamber.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
