Description

REFRIGERATOR WITH IMPROVED FOOD SPOILAGE SENSING
The present invention relates to a refrigerator, in particular to a refrigerator with a food spoilage sensing facility.
Refrigerators with food spoilage sensing facility are commonly known in the art.
This type of a refrigerator generally comprises: a chamber for storing and refrigerating food; a door for opening/closing the chamber; a sensing unit for sensing the level & of the volatile organic compounds which are released by the food in the chamber; a cleaning unit for cleaning the ambient air inside the chamber; and a control unit for determining the contamination level in the chamber based on the level * and for controlling the sensing unit and the cleaning unit, wherein the control unit has a food spoilage function for operating the cleaning unit. CN203758163(U) discloses a refrigerator with a food spoilage sensing facility.
In general, the food in the chamber immediately starts spoiling due to the
microorganism, and emits volatile organic compounds which a cause a bad taste and a bad smell. Some kind of food products such as meat and sausages spoil in a
comparatively shorter time. The user usually identifies the inedible food in the chamber only after it has developed a very heavy smell and a rotten appearance. In such cases, the sensing unit becomes saturated due to the high VOC concentrations. Thus, a problem with the prior art refrigerator is that the food spoilage sensing cannot be accurately conducted.
An objective of the present invention is to provide a refrigerator which solves the aforementioned problems of the prior art in a cost-effective way and which enables an improved sensing of the food spoilage. This objective has been achieved by the refrigerator as defined in claim 1, and the control method as defined in claim 15. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
In the refrigerator of the present invention the control unit is further adapted to determine the contamination level $ based on the currently sensed level R of the volatile organic compounds and a reference level ¾ of the volatile organic compounds which has been sensed by the sensing unit immediately after the preceding operation of the cleaning unit has been finished and the sensing unit has been initialized.
A major advantageous effect of the present invention is that the sensing of the food spoilage has been improved by virtue of the reference level ¾ which is sensed immediately after the last cleaning operation and the initialization of the sensing unit. Thereby the residual effects of the high VOC concentration on the sensing unit can be eliminated or reduced as much as possible, and the spoiling of the food can be early and accurately sensed. Another major advantageous effect of the present invention is that the quality of the food inside the chamber can be more reliably determined. Thereby, the performance of the food spoilage function of the refrigerator can be improved, and thus the preventive and protective actions against the food spoiling and the harmful VOC levels can be more reliably taken. Thereby, the user satisfaction can be increased.
