Monitoring system for food storage device

A monitoring system for a plurality of food storage apparatuses each of which includes a food storage cabinet for storing foodstuffs therein, a cooling device for cooling the interior of the storage cabinet, a manual setting device for preliminarily determining a desired temperature of the storage cabinet, a detection device for detecting an internal temperature of the storage cabinet and control means for applying a control signal based on the desired temperature and the detected internal temperature to the cooling device for controlling operation of the cooling device in such a manner that the interior of the storage cabinet is maintained at the desired temperature,

• wherein the food storage apparatuses each are provided with output means for issuing electric signals respectively indicative of the desired temperature, the detected internal temperature and an identity member for identifying each type of the food storage apparatuses outwardly, and wherein the monitoring system comprises a signal receiver for monitoring each operating condition of the food storage apparatuses on a basis of the electric signals applied thereto from said output means, said signal receiver including means responsive to the electric signals for determining each of the food storage apparatuses as being operated in an abnormal condition if the detected temperature becomes abnormal in relation to the desired temperature in the food storage apparatus identified by the identity number and alarm means for informing an operator of the abnormality in operation of the food storage apparatus identified by the identity number.
