Problems solved by technology

[0019] However, in the above-mentioned conventional structure, the infrared detection device 308 is arranged in the ice making compartment 301, therefore, for example, the static electricity charged by the human body and the friction of the towel etc. Static electricity, when the discharge energy works, due to the misoperation and failure of the infrared sensor 309, or the original part of the infrared sensor 309 itself is damaged, the detection function of the infrared sensor 309 stops working and cannot play a role, resulting in a decline in the quality of the refrigerator such problem

Abstract

Provided is a refrigerator including: an adiabatic basket configured by a plurality of adiabatic partitions; an adiabatic partition unit to partition the adiabatic basket; a storage chamber separated by the partition unit; an infrared sensor having a temperature detection unit which detects an infrared ray amount emitted from an object stored in the storage chamber; and an infrared ray collectingmember arranged deeper inside the storage chamber as compared to the infrared sensor. At least the inner wall of the infrared ray collecting member is formed so as to have a large heat holding effect.

Description

Technical field [0001] The invention relates to a refrigerator using an infrared sensor. Background technique [0002] In recent years, with the increasing demand for large-capacity refrigerators, refrigerators with increased volumetric efficiency by reducing ineffective space have been sold, as well as refrigerators with various designs in terms of use performance. [0003] Among them, in the past, in a refrigerator, in order to detect the temperature in the box, the air temperature in the box was measured with a thermistor or the like. For example, when hot food is put in, the temperature of the air in the box heated by the influence of the hot food is measured by a plurality of thermistors installed in the box to adjust the cooling amount. However, in this type of refrigerator, the actual temperature of the food is not measured, so it is actually not known whether the food can be cooled. Therefore, when cooling the food, the food is cooled to the target temperature while cooli...
