Refrigerating and freezing device and its overheating prompting method

Abstract

The invention provides a refrigeration and freezing device and an overheating prompt method thereof. The overheating prompt method comprises the steps that the opening event of a door of the refrigeration and freezing device is detected; after opening of the door is determined, the environmental temperature of the position where the refrigeration and freezing device is located and temperature distribution in the front set area of a box of the refrigeration and freezing device are detected; temperature distribution is compared with the environmental temperature, and the temperature of articles to be put into the refrigeration and freezing device is determined; and whether the temperature of the articles is higher than a temperature threshold value matched with the environmental temperature or not is judged, and if yes, a first article overheating prompt signal is output. By adoption of the refrigeration and freezing device, a user can be prompted to stop operation of putting of overheating articles, the phenomenon that the refrigeration and freezing device increases the refrigeration load to cool the overheating articles is avoided, and therefore energy consumption of the refrigeration and freezing device is reduced, and the refrigeration efficiency of the refrigeration and freezing device is improved.

Description

technical field [0001] The invention relates to a storage device, in particular to a refrigerating and freezing device and an overheating prompting method thereof. Background technique [0002] A refrigerating and freezing device, such as a refrigerator, is a household appliance that keeps food or other items in a constant low temperature and cold state. At present, a refrigerating and freezing device has become an indispensable appliance in the family. Existing refrigerating and freezing devices generally include direct cooling and There are two types of air-cooled. [0003] The performance of refrigeration and freezing devices mainly includes: the stability of the storage environment and energy consumption. The former requires that the temperature and humidity of the storage space inside the refrigerating and freezing device be kept within the set index range with less fluctuation; the latter requires that the refrigerating and freezing device consume as little power as p...

Problems solved by technology

[0004] However, during normal use, some users will directly put high-temperature food into the refrigerator without preliminary cooling. Such use will seriously affect the performance of the refrigerator. On the one hand, overheated items will radiate heat to the surroundings during the cooling process. , will create an environment suitable for the survival of bacteria in the refrigerator and freezer, resulting in accelerated reproduction of bacteria, which greatly destroys the storage environment of stored items, especially food

On the other hand, in order to quickly cool down items, the refrigerating and freezing device needs to increase the compressor load, resulting in a decrease in the cooling effect of the compressor and other refrigerating devices, resulting in an increase in the energy consumption of the refrigerating and freezing device, and in severe cases, shortening the service life of the refrigerating device. life span
