It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The quick cooling function mode of the refrigerating chamber of the refrigerator in the related art has the following problems:
1. the current complicated operation that a user needs to manually press a key to start a refrigeration function mode is low in efficiency and not improved in intelligent practical degree;
2. the refrigerating efficiency of the refrigerating chamber is low, and the temperature difference between the upper and lower regions of the chamber is large, so that the temperature uniformity control and the storage effect improvement are not facilitated;
3. when a large amount of heat load food materials are stored in the refrigerating chamber, the whole temperature uniformity and balance are influenced, the food materials are not guaranteed and kept fresh by too high or too low temperature, and the energy consumption is further increased;
4. the frequency conversion electric control air-cooled refrigerator has a single energy-saving and power-saving mode, lacks a functional control program to optimize the running mode of the compressor, and reduces frequent refrigeration startup and shutdown to achieve energy conservation and consumption reduction.
During the operation of the refrigerator, cold air in the freezing chamber enters the refrigerating chamber through the refrigerating air cover, the cold air in the freezing chamber generally has minus ten degrees, the air circulation in the refrigerating chamber generally is from top to bottom, and when the refrigerating chamber cools and stores articles, the articles can absorb cold energy, which means that the temperature below the cold air entering the refrigerating chamber is higher than the temperature above the cold air entering the refrigerating chamber during the refrigerating period of the refrigerating chamber.
The invention provides a control method of a refrigerator. Fig. 1 is a method schematic diagram of an embodiment of a control method of a refrigerator according to the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110 and step S120.
Step S110, detecting whether a temperature difference between a lower half temperature and a set temperature of a refrigerating compartment of the refrigerator is greater than or equal to a first preset temperature difference threshold and/or whether a temperature difference between an upper half temperature and a set temperature is greater than or equal to a second preset temperature difference threshold.
And step S120, if the temperature difference between the lower half area temperature and the set temperature is detected to be larger than or equal to a first preset temperature difference threshold value and/or the temperature difference between the upper half area temperature and the set temperature is detected to be larger than or equal to a second preset temperature difference threshold value, starting a cold storage chamber quick cooling mode of the refrigerator.
The refrigerating chamber is divided into an upper half area and a lower half area according to the geometric center position of the space. Temperature detection means (for example, temperature sensors) are provided in the upper half area and the lower half area, respectively, and the upper half area temperature T1 and the lower half area temperature T2 are detected. Optionally, two temperature detection devices are arranged on a refrigerating air hood of the refrigerating chamber to respectively detect the temperatures of the upper half area and the lower half area of the refrigerating chamber, so that the accuracy of detecting the temperatures of the upper area and the lower area of the refrigerating chamber is higher, and the intelligent control is more convenient. The two temperature detection devices are respectively arranged on the refrigerating fan cover at the positions corresponding to the upper half area and the lower half area of the refrigerating chamber. For example, referring to fig. 2, fig. 2 shows a schematic diagram of an arrangement of temperature sensors according to a specific example of the present invention. As shown in fig. 2, a temperature sensor 1 and a temperature sensor 2 are provided on the refrigerating fan cover at positions corresponding to the upper half and the lower half of the refrigerating compartment, respectively.
And starting a cold storage chamber quick cooling mode of the refrigerator, specifically, the method may include controlling a cold storage air door of the cold storage chamber to be opened, and controlling a compressor of the refrigerator to operate according to a set rotating speed, wherein the set rotating speed is greater than a rotating speed of the refrigerator operating according to a normal control logic, so that quick cooling of the cold storage chamber is realized. Optionally, when the refrigerator is controlled to start the cold storage compartment quick cooling mode, other compartments of the refrigerator (except for the cold storage compartment) are controlled to operate according to normal control logic. The normal control logic may specifically include controlling the operation of the refrigerator according to set parameters, for example controlling the operation of the compressor according to set temperatures of the various compartments.
Preferably, whether the temperature difference between the temperature of the lower half area of the refrigerating chamber and the set temperature is greater than or equal to a first preset temperature difference threshold value is detected; and if the temperature difference between the lower half area temperature and the set temperature is detected to be greater than or equal to a first preset temperature difference threshold value, controlling the refrigerator to start a cold storage chamber quick cooling mode. If the temperature difference between the lower half area temperature and the set temperature is smaller than a first preset temperature difference threshold value, detecting whether the temperature difference between the upper half area temperature and the set temperature of the refrigerating chamber is larger than or equal to a second preset temperature difference threshold value or not; and if the temperature difference between the upper half area temperature and the set temperature is detected to be greater than or equal to a second preset temperature difference threshold value, controlling the refrigerator to start a cold storage chamber quick cooling mode.
The refrigerator normally runs in a power-on state, and the temperature T1 of the upper half area of the refrigerating chamber and the temperature T2 of the lower half area of the refrigerating chamber are monitored in real time; set temperature T Is provided with A first preset temperature difference threshold value a and a second preset temperature difference threshold value b; judging T2-T Is provided with And a is not less than a, if yes, the refrigerating chamber operates in a refrigerating state, and simultaneously, the quick cooling mode of the refrigerating chamber is started. If T2-T Is provided with If a is not satisfied, judging T1-T Is provided with And b is not less than b, if yes, the refrigerator operates according to a normal mode, and a quick cooling mode of the refrigerating chamber is started. The set temperature may specifically be a user set temperature; the set temperature T Is provided with The value range may specifically include:2-8 ℃; the value range of the first preset temperature difference threshold value a can specifically include 1.5-2.5 ℃, and preferably can be 2 ℃. The value range of the second preset temperature difference threshold value b can specifically comprise 1.5-2.5 ℃, and preferably can be 2 ℃.
During the operation of the refrigerator, cold air in the freezing chamber enters the refrigerating chamber through the refrigerating fan cover, the cold air in the freezing chamber generally has minus ten degrees, the air circulation of the refrigerating chamber generally is from top to bottom, and when the refrigerating chamber is used for cooling and storing articles, the articles can absorb cold energy, which means that the temperature of the lower part of the cold air entering the refrigerating chamber is higher than the temperature of the upper part of the cold air during the refrigerating period of the refrigerating chamber due to the fact that the cold air is heated, therefore, whether the temperature of the lower half area meets the requirement or not is judged firstly, the refrigerating operation of the refrigerating chamber can be controlled when the temperature of the lower half area does not meet the requirement, and meanwhile, the functional mode is started. If the temperature of the lower half area does not meet the requirement, whether the temperature of the upper half area meets the requirement is judged, and therefore the overall refrigerating efficiency of the refrigerating chamber is improved according to the difference of the upper temperature and the lower temperature.
Fig. 3 is a method schematic diagram of another embodiment of a control method of a refrigerator provided by the present invention. As shown in fig. 3, based on the above embodiment, according to another embodiment of the present invention, the control method further includes step S130.

Specifically, if the temperature difference between the upper half area temperature and the lower half area temperature is less than or equal to a third preset temperature difference threshold, the refrigerator is controlled to operate according to a normal control logic. The value range of the third preset temperature difference threshold value c may include, for example, -0.5 to-2 ℃, and preferably-1 ℃. Preceding determination of T2-T Is provided with ≥a、T1-T Is provided with ≧ b corresponds to the calibration of two temperature detection means (e.g., sensors), and T1-T2 corresponds to the calibration of the temperature of the entire refrigerated compartment, which ensures that the upper and lower portions of the refrigerated compartment conform to the design temperature while ensuring the uniformity of the overall temperature of the compartment. If it is detectedAnd if the temperature difference between the upper half area temperature and the lower half area temperature is less than or equal to a third preset temperature difference threshold value c, controlling the refrigerator to operate according to a normal control logic.

Preferably, whether the temperature difference between the lower half temperature of the refrigerating compartment and the set temperature is greater than or equal to a first preset temperature difference threshold value is detected; and if the temperature difference between the lower half zone temperature and the set temperature is detected to be greater than or equal to a first preset temperature difference threshold value, controlling the refrigerator to start a cold storage chamber quick cooling mode. If the temperature difference between the lower half area temperature and the set temperature is smaller than a first preset temperature difference threshold value, whether the temperature difference between the upper half area temperature and the set temperature of the refrigerating chamber is larger than or equal to a second preset temperature difference threshold value is detected; and if the temperature difference between the upper half area temperature and the set temperature is detected to be greater than or equal to a second preset temperature difference threshold value, controlling the refrigerator to start a cold storage chamber quick cooling mode. The specific steps refer to the foregoing step S110 and step S120, which are not described herein again.
