Claims (1)

[Scope of Claim for Utility Model Registration] (1) A refrigerator in which the inside of the refrigerator is divided into a plurality of compartments, one of the compartments is a refrigerating compartment, and each compartment is cooled by forced circulation of cold air, A damper thermostat for adjusting the amount of cold air blown out is installed at the back of the upper part of the refrigerator compartment, a communication duct for blowing cold air is installed in connection with the lower part of the decorative cover that covers the damper thermostat, and a A refrigerator comprising a cold air outlet arranged for each of a plurality of compartment shelves, and a temperature adjustment means for detecting temperatures at a plurality of locations in the refrigerator compartment and controlling the damper thermostat. Temperature control device. (2) The cold air outlet installed in the communication duct is
2. The temperature control device for a refrigerator according to claim 1, wherein the refrigerator compartment is divided into a plurality of shelves and is disposed near the lower surface of each shelf. (3) The temperature adjustment means for controlling the damper thermostat by detecting temperatures at a plurality of locations in the refrigerator compartment includes a temperature detection element for sensing room temperature arranged in each compartment shelf in the refrigerator compartment; Refrigerator temperature adjustment according to claim 1 or 2, characterized in that the temperature detected by a plurality of temperature detection elements and the set temperature are compared to control the opening/closing operation of a damper thermostat. Device. (4) The opening/closing operation of the damper thermostat is controlled by comparing the temperatures detected by the plurality of temperature detection elements and the set temperature by determining a representative value from the temperatures detected by the plurality of temperature detection elements, and If the representative value is higher than the set temperature, the damper thermostat is opened, and if the representative value is lower than the set temperature, the damper thermostat is closed. and a practical use characterized in that the opening/closing operation of the damper thermostat is controlled when the temperature detected by any one of the plurality of temperature detection elements is outside the range from the set temperature to a predetermined temperature, regardless of the set temperature. A temperature regulating device for a refrigerator according to claim 3 of the patent registration claim. (5) The representative value determined from the temperatures detected by the plurality of temperature detection elements is characterized in that any one of the plurality of temperature detection elements is used as a representative temperature detection element, and the detected temperature is taken as the representative value. A temperature regulating device for a refrigerator according to claim 4 of the utility model registration claim. (6) The representative value determined from the detected temperatures of the plurality of temperature detecting elements is obtained by averaging the respective detected temperatures of the plurality of temperature detecting elements and using the average value as the representative value of the detected value. A temperature regulating device for a refrigerator according to claim 4 of the patent registration claim. (7) Control of the opening/closing operation of the damper thermostat when the temperature detected by any one of the plurality of temperature detection elements is outside the range of the predetermined temperature from the preset temperature, regardless of the representative value and the preset temperature. Utility model registration claim 4 is characterized in that the damper thermostat is brought into a closed state when the lowest temperature among the temperatures detected by each temperature detection element falls below a predetermined temperature range from the set temperature.
Refrigerator temperature adjustment device as described in section. (8) Control of the opening/closing operation of the damper thermostat when the temperature detected by any one of the plurality of temperature detection elements is outside the range of the predetermined temperature from the preset temperature, regardless of the representative value and the preset temperature. Utility model registration claim 4 is characterized in that the damper thermostat is brought into an open state when the highest temperature among the temperatures detected by each temperature detection element exceeds a predetermined temperature range from the set temperature.
Refrigerator temperature adjustment device as described in section.
