But sometimes, due to the sudden disturbance of the air flow or the interference of the electromagnetic signal, the temperature value will suddenly change, and then quickly return to normal.
For example, sometimes the temperature values collected by the temperature sensor are: 5.2, 5.3, 5.2, 15, 5.3, 5.2, 5.5. It is obvious that the value of 15 is an abnormal value and needs to be filtered out, otherwise the refrigerator will judge that refrigeration is needed, resulting in energy waste And cause abnormal switching of related load of the refrigerator

Embodiment Construction
[0039] figure 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. see figure 1 , the refrigerator may generally include a box body 110 . The box body 110 can be surrounded by a top wall, a bottom wall, a rear wall and two left and right side walls. A door body (not shown) is arranged in front of the box body 110, and the door body can be connected to the side wall by a pivot structure. A plurality of storage compartments 140 are defined inside the box body 110 . Adjacent storage compartments 140 can be separated by partitions 120 .
[0040] An infrared sensor 130 is disposed inside the storage compartment 140 for detecting the temperature of the storage compartment 140 . The number of infrared sensors 130 can be set according to the number of storage compartments 140 , and each storage compartment 140 can be provided with an infrared sensor 130 .
[0041] In order to improve the temperature sensing accuracy of the inf...

The invention provides a refrigerator and a refrigerating method thereof. The refrigerator comprises infrared sensors used for detecting the temperatures of storage chambers of the refrigerator correspondingly. The refrigerating method comprises the steps that A, temperature values detected by the infrared sensors are acquired after a door body of the refrigerator is closed; B, whether the currently acquired temperature values are changed suddenly or not is judged, if yes, the step C is directly implemented, and if not, the step D is implemented directly; C, temperature values acquired last time serve as the temperature values currently involved in refrigerator refrigerating judgment; and D, the currently acquired temperature values serve as the temperature values currently involved in refrigerator refrigerating judgment, temperature values detected by the infrared sensors are acquired continuously, and the step B is implemented again. According to the refrigerator and the refrigerating method thereof, measuring values in accordance with actual temperatures of the storage chambers are obtained as the temperature values involved in refrigerator refrigerating judgment by judging whether the temperatures detected by the infrared sensors are changed suddenly or not, and accordingly refrigeration of the refrigerator is more precise.
Description
technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigerator and a refrigeration method thereof. Background technique [0002] Existing refrigerators usually use a temperature sensor arranged inside the storage compartment to sense the temperature around the location where it is arranged, and use the temperature as a basis for refrigeration control. When this control method is used for refrigeration control, when the temperature measured by the temperature sensor is higher than a preset value, the refrigerator starts the refrigeration system for refrigeration. When the door of the refrigerator is closed, usually the difference between two adjacent collected temperature values is small. But sometimes, due to the sudden disturbance of the air flow or the interference of the electromagnetic signal, the temperature value will suddenly change, and then quickly return to normal. For example, sometimes the temperature values collect...
