Detailed Description
An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.
The first embodiment is as follows:
as shown in fig. 1, an embodiment of the present invention provides a self-regulation control method for a refrigerating temperature of a refrigerator, including the following steps:
s1, presetting a first preset temperature Ts1, a second preset temperature Ts2 and a first preset time Ts1; wherein Ts1< Ts2;
s2, acquiring a first refrigerating temperature Tc1 at the middle part of the refrigerating chamber and a second refrigerating temperature Tc2 at the upper end of the refrigerating chamber, wherein a first temperature sensor and a second temperature sensor are respectively arranged at the middle part of the refrigerating chamber and the upper end of the refrigerating chamber to monitor temperature data at the two positions;
s3, judging whether the current first refrigeration temperature Tc1 is less than or equal to a target temperature value, if so, closing the compressor and the fan, otherwise, starting the compressor and the fan; the target temperature value refers to a temperature value set by a user independently, for the single-cycle air-cooled refrigerator, the temperature is adjusted through a mechanical switch, the mechanical switch has different gears, and for each gear, a temperature value is correspondingly set when the refrigerator leaves a factory, namely the target temperature value in the embodiment. When the current first refrigerating temperature Tc1 is less than or equal to the target temperature value, the refrigerating chamber reaches the temperature set by the user independently, and the compressor and the fan are closed without continuously refrigerating; on the contrary, the temperature of the refrigerating chamber is too high, the temperature does not reach the temperature for self setting, and a compressor and a fan are required to be started for refrigeration, so that the temperature is reduced;
s4, judging whether the current second refrigeration temperature Tc2 is less than or equal to a first preset temperature Ts1; since the first refrigerating temperature Tc1 is located in the middle of the refrigerating compartment, representing the overall temperature of the refrigerating compartment, but the temperature distribution in the refrigerating compartment is unbalanced (the lower part is cold, and the upper part is high), it is necessary to monitor the upper temperature of the refrigerating compartment, that is, the second refrigerating temperature Tc2. For the first preset temperature Ts1, if the second refrigerating temperature Tc2 is greater than the first preset temperature Ts1, an air blockage may occur, and the air blockage prevention operation mode needs to be started, otherwise, the refrigerator is normally refrigerated without additional operation.
Therefore, if the current second refrigerating temperature Tc2 is less than or equal to the first preset temperature Ts1, it is determined whether the refrigerator is in the wind blockage prevention operation mode, and when the refrigerator is in the wind blockage prevention operation mode, the wind blockage prevention operation mode is closed and S2 is returned (at this time, it means that the refrigerator is normally refrigerated, and the wind blockage prevention mode does not need to be started, so that the refrigerator is closed if the refrigerator is in the wind blockage prevention operation mode); when the wind blockage prevention operation mode is in a closed state, returning to S2;
if the current second refrigerating temperature Tc2 is higher than the first preset temperature Ts1, the refrigerator is abnormally refrigerated, and S5 is executed;
s5, judging whether the current second refrigerating temperature Tc2 is greater than a second preset temperature Ts2, if so, indicating that the refrigerating of the refrigerator is abnormal and whether temporary abnormality caused by temperature fluctuation and other conditions needs to be further observed, executing S6 for judgment, and otherwise, returning to S2;
s6, acquiring the duration time t1 of the second refrigerating temperature Tc2 being more than the second preset temperature Ts2 and monitoring whether the current second refrigerating temperature Tc2 is more than the second preset temperature Ts2; if yes, executing S7, otherwise, returning the value of t1 to zero and returning to S2; the duration time t1 that the second refrigerating temperature Tc2 is greater than the second preset temperature Ts2 is obtained and is used for judging the duration time of temperature abnormity, and further judging whether the temporary fluctuation or the wind blockage occurs according to the duration time. If the temperature value of the second refrigerating temperature Tc2 is reduced to be less than or equal to the second preset temperature Ts2 in the process of monitoring t1, the temperature is restored to be normal, and no further processing is needed, so that t1 is reset to zero and returns to S2.
S7, judging whether the t1 value is larger than a first preset time ts1 or not;
if yes, the refrigerator refrigeration is determined to be abnormal and cannot be adjusted to a normal state, whether the refrigerator is in the wind blockage prevention operation mode or not is further judged, and when the refrigerator is in the wind blockage prevention operation mode, the wind blockage prevention operation mode is kept and S2 is returned; when the wind blockage prevention operation mode is in a closed state, starting the wind blockage prevention operation mode and returning to S2;
otherwise, the refrigeration abnormity of the refrigerator is short-term fluctuation or temporary abnormity, the refrigerator is not in a wind blockage state, and the step returns to S2.
Example two:
due to the fact that frosting of the evaporator is serious when the humidity is high or other abnormal conditions exist, the temperature of the upper portion of the refrigerating chamber is increased rapidly along with the frosting amount of the evaporator, and therefore defrosting operation needs to be conducted according to the temperature change condition.
Therefore, as shown in fig. 2, in this embodiment on the basis of the first embodiment, S1 further includes: presetting a third preset temperature Ts3 and a second preset time Ts2, wherein Ts1 is less than Ts2 and less than Ts3;
unlike the first embodiment, S7 in the present embodiment includes:
judging whether the t1 value is larger than a first preset time ts1 or not;
if yes, judging whether the refrigerator is in a wind blockage prevention operation mode, and when the refrigerator is in the wind blockage prevention operation mode, keeping the wind blockage prevention operation mode and executing S8; when the wind blockage prevention operation mode is in a closed state, starting the wind blockage prevention operation mode and executing S8;
otherwise, returning to S2;
s8, judging whether the current Tc2 value is greater than a third preset temperature Ts3 or not;
if yes, the temperature of the upper part of the refrigerating chamber is increased to a higher temperature, whether defrosting is needed to be further judged, and S9 is executed;
otherwise, returning to S2;
s9, acquiring the duration time t2 that the second refrigerating temperature Tc2 is greater than the third preset temperature Ts3, and monitoring whether the current second refrigerating temperature Tc2 is greater than the third preset temperature Ts3; if yes, executing S10, otherwise, returning the t2 value to zero and returning to S2; the duration time t2 for which the second refrigeration temperature Tc2 is greater than the third preset temperature Ts3 is obtained and is used for judging the duration time of temperature abnormality, and whether defrosting needs to be started is further judged according to the duration time. If the temperature value of the second refrigerating temperature Tc2 is reduced and is less than or equal to the second preset temperature Ts3 in the process of monitoring t2, it means that defrosting does not need to be started, so t2 is reset to zero and returns to S2.
S10, judging whether the value of t2 is larger than a second preset time ts2 or not; if yes, the refrigerator starts a defrosting mode, closes the wind blockage prevention mode and returns to S2, and otherwise, the refrigerator returns to S2.
Example three:
on the basis of the first or second embodiment, in this embodiment, S1 further includes:
presetting a first preset rotating speed S1, a second preset rotating speed S2, a third preset rotating speed S3 and a fourth preset rotating speed S4, wherein S1 is greater than S3, and S2 is greater than S4; wherein, the first and the second end of the pipe are connected with each other,
