Referring to fig. 1, fig. 1 is a flowchart of a method for controlling a temperature of a refrigeration compartment according to an embodiment of the present invention, and an exemplary embodiment of the method for controlling a temperature of a refrigeration compartment according to the present invention is described. It is to be understood that the illustration in FIG. 1 and the following illustrations are merely exemplary of the invention and are not to be construed as limiting the invention in any way; any suitable improvement or modification within the spirit of the invention is included within the scope of the invention.
As shown in fig. 1, in a first aspect, an embodiment of the present invention provides a method for controlling a temperature of a refrigeration compartment, which may include the following steps:
detecting whether the refrigeration sensor is in a failure state;
responding to the failure state of the refrigeration sensor, namely acquiring the ambient temperature and the gear set by the refrigeration chamber when the refrigeration sensor is in the failure state;
and selecting a failure control mode of the refrigeration sensor based on the acquired environment temperature and the gear set in the refrigeration compartment.
It should be noted that the "failure state" herein means that the refrigeration sensor is temporarily in a temperature-sensitive failure state, but the refrigeration sensor itself does not malfunction, that is, the refrigeration sensor is in a "false failure".
Further, since the cooling compartment has different stages, the temperature at which cooling is requested to start and the temperature at which cooling is requested to stop corresponding to the different stages, and the temperature at which cooling is requested to start and the temperature at which cooling is requested to stop corresponding to the same stage are different due to the different ambient temperatures, both factors need to be considered together.
According to the refrigeration compartment temperature control method provided by the embodiment of the invention, whether the refrigeration sensor is in a failure state or not is detected, and when the refrigeration sensor is detected to be in the failure state, the ambient temperature and the gear set by the refrigeration compartment are obtained; and based on the acquired environmental temperature and the gear set in the refrigeration compartment, selecting a failure control mode of the refrigeration sensor. When the refrigeration sensor enters the failure control mode, the temperature of the refrigeration chamber is controlled in the control mode in the failure control mode, and the refrigeration sensor is not used for controlling the temperature of the refrigeration chamber, so that the temperature of the refrigeration chamber is not too low, food is not frozen, the temperature of the gear of the refrigeration chamber at the current ambient temperature is ensured, the accuracy of temperature control is ensured, and the satisfaction degree of a user is improved.
Of course, it should be noted that, when detecting whether the refrigeration sensor is in the failure state and responding to that the refrigeration sensor is not in the failure state, the refrigeration sensor may perform normal refrigeration compartment temperature control.
In one embodiment of the present invention, the step of selecting a failure control mode of the refrigerant sensor comprises:
based on the obtained gear corresponding relationship between the ambient temperature and the refrigeration compartment, the corresponding refrigeration compartment startup refrigeration duration and shutdown waiting duration are selected, and the failure control mode of the refrigeration sensor in this embodiment is described below by taking table 1 as an example.
For example, according to one embodiment, an exemplary ambient temperature and gear mapping relationship of the refrigeration compartments is shown in table 1 below, and the start-up and cooling durations and the stop waiting durations corresponding to the refrigeration compartments are selected. It should be understood that the following table 1 is provided merely as an exemplary embodiment, and that the specific cooling compartment on-cooling duration and off-waiting duration may be adjusted and set accordingly as desired, and the present invention is not limited to any particular situation or situations.
TABLE 1
For example, when the ambient temperature is 20 ℃ and the gear of the refrigeration compartment is a middle gear, the failure control mode of the selected refrigeration sensor corresponds to the starting refrigeration time length of 12min (minutes) and the stopping refrigeration time length of 60min (minutes).
According to one embodiment of the present invention, the step of detecting whether the refrigerant sensor is in a failure state includes:
acquiring the cooling or heating rate of the refrigeration sensor, and comparing the cooling or heating rate with the preset cooling or heating rate at the current ambient temperature;
executing a step of responding to the failure state of the refrigeration sensor based on the detection that the temperature reduction or temperature rise rate of the refrigeration sensor is less than or equal to a preset temperature reduction or temperature rise rate which is multiplied by a first set coefficient, namely executing the next step of acquiring the ambient temperature and the gear set by the refrigeration compartment; and then selecting a failure control mode of the refrigeration sensor based on the acquired environment temperature and the set gear of the refrigeration compartment.
In this embodiment, taking the first setting coefficient of 0.35 as an example, that is, when the cooling or heating rate of the refrigeration sensor is less than or equal to 0.35 times of the preset cooling or heating rate, the refrigeration sensor is in a failure state.
Of course, the first setting coefficient can be adjusted and set accordingly as required.
According to an embodiment of the present invention, the step of detecting whether the refrigeration sensor is in a failure state further includes:
detecting whether a door opening operation occurs;
in response to detection of the door opening operation, the control is performed after the door is closed for a first set time (e.g., 10 minutes). Of course, the first setting time may be set according to actual needs, and is not limited to the above example.
Because the temperature in the refrigerating chamber fluctuates after the door is opened, the cooling or heating rate of the refrigerating sensor is detected, and the step of comparing the temperature with the preset cooling or heating rate at the current ambient temperature is used for eliminating the interference factor, so that the door opening factor is considered before the step of detecting the cooling or heating rate of the refrigerating sensor and comparing the temperature with the preset cooling or heating rate at the current ambient temperature, and the detection can be ensured to be more accurate through time delay detection.
Of course, if the door opening operation does not occur, the step of detecting the cooling or heating rate of the refrigeration sensor and comparing the detected cooling or heating rate with the preset cooling or heating rate at the current ambient temperature is immediately started.
According to an embodiment of the present invention, the step of obtaining a temperature decrease or increase rate of the refrigeration sensor and comparing the temperature decrease or increase rate with a preset temperature decrease or increase rate at the current ambient temperature may specifically include:
and acquiring the cooling or heating rate of the refrigeration sensor once every second set time (for example, 3 minutes), and comparing the average value of the cooling or heating rates of the refrigeration sensor for multiple times (for example, 3 times) with the preset cooling or heating rate at the current ambient temperature to reduce the detection error and improve the detection accuracy. Of course, the second setting time can be adjusted and set correspondingly according to needs, and the number of times that the cooling or heating rate of the refrigeration sensor is used for averaging can also be adjusted correspondingly according to specific needs.
According to one embodiment of the present invention, the method further comprises the steps of continuously performing the steps of obtaining the cooling or heating rate of the refrigeration sensor and comparing the obtained cooling or heating rate with the preset cooling or heating rate at the current ambient temperature in response to the failure control mode of the refrigeration sensor, that is, when the refrigeration sensor is in a "false failure";
and if the cooling or heating rate of the refrigeration sensor is detected to be recovered to be normal, the refrigeration sensor is recovered to be normal, the failure control mode of the refrigeration sensor is quitted, and the refrigeration sensor controls the temperature of the refrigeration chamber again.
According to one embodiment of the invention, the step of returning the temperature decrease or increase rate of the refrigeration sensor to normal comprises the following steps:
comparing the cooling or heating rate of the refrigeration sensor with a preset cooling or heating rate at the current ambient temperature, wherein the cooling or heating rate of the refrigeration sensor is greater than the preset cooling or heating rate multiplied by a second set coefficient; in this embodiment, the second setting coefficient is 0.7, that is, when the cooling or heating rate of the refrigeration sensor is greater than 0.7 times of the preset cooling or heating rate, the refrigeration sensor returns to normal. Of course, the second setting coefficient can be adjusted and set accordingly as required.
According to an embodiment of the present invention, based on the step of comparing the cooling or heating rate of the refrigeration sensor with the preset cooling or heating rate at the current ambient temperature, if it is detected that the cooling or heating rate of the refrigeration sensor is less than or equal to the preset cooling or heating rate multiplied by the second set factor and greater than the preset cooling or heating rate multiplied by the first set factor, that is, the preset cooling or heating rate multiplied by 0.35 is less than the preset cooling or heating rate multiplied by 0.7 or less than the cooling or heating rate of the refrigeration sensor, the current step is skipped and a next comparison result is waited, that is, when the cooling or heating rate of the refrigeration sensor is within the value range, it is temporarily not determined whether the refrigeration sensor is in a failure state, and the next comparison result is waited to avoid erroneous determination.
According to an embodiment of the present invention, if the next comparison result is that the cooling or heating rate of the refrigeration sensor is still less than or equal to the preset cooling or heating rate multiplied by the second set factor and greater than the preset cooling or heating rate multiplied by the first set factor, it is seen that the state of the refrigeration sensor is still unchanged, it can be determined that the refrigeration sensor is in the failure state.
It can be understood that, if the cooling or heating rate of the refrigeration sensor becomes greater than 0.7 times of the preset cooling or heating rate, it can be determined that the refrigeration sensor is recovered to be normal.
In a second aspect, an embodiment of the present invention further provides a refrigeration control system, including:

a shift position sensor configured to acquire a shift position of the cooling compartment;
and the control module is configured to select a failure control mode of the refrigeration sensor based on the acquired ambient temperature and the gear position of the refrigeration compartment when the refrigeration sensor is in the failure state mode. Therefore, when the refrigeration sensor enters the failure control mode through the control module, the temperature of the refrigeration chamber is controlled in a control mode in the failure control mode, and the refrigeration sensor is not used for controlling the temperature of the refrigeration chamber, so that the temperature of the refrigeration chamber is not too low, food is not frozen, the temperature of the refrigeration chamber at the gear of the refrigeration chamber at the current ambient temperature is ensured, the accuracy of temperature control is ensured, and the satisfaction degree of a user is improved.
