Refrigerator

Abstract

The invention provides a refrigerator. The refrigerator comprises a refrigerator body, a rack component, a synchronous belt transmission component, a sliding block and an infrared sensing device; a storage chamber is restricted to the interior of the refrigerator body, the rack component comprises one or more partition boards arranged horizontally, so that the storage chamber is divided into multiple storage spaces in the vertical direction, the synchronous belt transmission component is arranged in the storage chamber and located in the same vertical plane with a synchronous belt, the synchronous belt comprises a vertical segment which penetrates through the multiple storage spaces and is arranged vertically, the sliding block is fixedly arranged on the vertical segment so that the sliding block can be driven by the synchronous belt transmission component to move vertically, the infrared sensing device is fixedly arranged on the sliding block and towards the storage chamber, the infrared sensing device is assembled to sense and test infrared rays released by objects placed on the multiple storage spaces, and the surface temperature of the objects is confirmed. By means of the refrigerator, the best storage environment can be provided for food in the refrigerator, nutrition draining of the food is reduced, and the hardware cost of the sensor is saved.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a refrigerator. 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. [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 rise only after the temperature of the item is transmitted to the roo...

AI Technical Summary

Problems solved by technology

During this process, the temperature of the item may be transmitted to other items in contact with it, resulting in a change in the temperature of the food already stored in the refrigerator, resulting in loss of nutrition and reduced storage effect

[0004] In addition, when the storage compartment is divided into multiple relatively independent storage spaces by shelf partitions, the temperature in the storage space where items have just been placed may be higher than other storage spaces, and the temperature of the existing refrigerator will be used. The control method needs to refrigerate the entire storage room as a whole, resulting in a waste of electric energy

[0005] In the prior art, there are also multiple temperature sensors installed in the storage room to detect the temperature in different areas of the storage room respectively. On the one hand, it leads to cost. It is still difficult to avoid the impact on item storage
