Embodiment Construction

[0029] figure 1 is a schematic structural block diagram of a refrigerator 100 according to an embodiment of the present invention. The refrigerator 100 may generally include: a box body 110 , a door body 130 , a door opening detection device 140 , a shelf assembly 120 , and an infrared sensor assembly 150 .

[0030] Among the above components, a storage compartment is defined inside the box body 110, and the shelf assembly 120 is arranged inside the storage compartment to divide the storage compartment into a plurality of storage spaces. The box body 110 may be surrounded by a top wall, a bottom wall, a rear wall and two left and right side walls. The shelf assembly 120 may include at least one horizontal partition to vertically divide the storage compartment into a plurality of storage spaces. The storage space above each shelf can be used to place different items to make full use of the storage space.

[0031] The door body 130 is pivotally disposed at the front of the bo...

Abstract

The invention provides a refrigerator and a detection method of an inner temperature of the refrigerator. The refrigerator comprises a box body, a door body, a door opening detection device, a rack assembly and an infrared sensing assembly, wherein a storage chamber is limited in the box body; the door body is pivotally arranged at the front part of the box body; the door opening detection device is configured to detect an opening / closed state of the door body; the rack assembly is arranged in the storage chamber and is used for separating the storage chamber into a plurality of storage spaces; the infrared sensing assembly is arranged on an inner wall of the box body and is configured to sense infrared rays released by objects arranged in the plurality of storage spaces when the door body is in a closed state, so that the surface temperatures of the objects are determined. With the adoption of the technical scheme, interferences on the sensing of the infrared sensing assembly by an external heat source after the door body is opened are avoided, and sensing deviation of the infrared sensing assembly, caused by the fact that arms of a user stretch into the storage space, is prevented, so that the refrigerator can operate stably.

Description

technical field [0001] The invention relates to refrigerating and freezing equipment, in particular to a refrigerator and a detection method for its internal temperature. Background technique [0002] Traditional 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. [0003] However, when using this control method to control the refrigerator, when the temperature measured by the temperature sensor is higher than the preset value, the refrigerator starts cooling. During the actual use of the refrigerator, the user will often access the items stored in the compartment. The temperature of the items just placed is generally high, and it takes a certain amount of time for the temperature of the items to be transmitted to the storage space through thermal radiation. The temperature sensed by the temperature sensor will r...
