Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and in particular to a refrigeration air duct temperature sensor installation structure and a refrigerator. Background Art

[0002] At present, the air inlet control of the cold storage air duct of the air-cooled refrigerator is generally controlled by an electric damper, and the indoor temperature of the refrigerator compartment is monitored by a temperature sensor. When the temperature exceeds the set temperature, the temperature sensor will feed back a signal to the main board, and the main board will control the electric damper to open, and cold air will enter the cold storage compartment, thereby reducing the indoor temperature of the cold storage compartment; when the temperature of the cold storage compartment reaches the set temperature, the main board will control the electric damper to close, and cold air will no longer enter the cold storage compartment.

[0003] Since the current air-cooled refrigerator refrigeration air duct components adopt a full-width duct structure design, the distance from the duct components to the box side is generally less than 25mm, and the duct adopts the side air outlet method on both sides, so when the cold air enters the cold storage box, it must first pass through the long tunnel on the cold storage air hood, then hit the side wall of the cold storage box, and finally the cold air surrounds the entire cold storage compartment and converges in the middle of the compartment.

[0004] However, when the cold air passes through the upper tunnel of the refrigerated air hood, the cold air will rush out, and when the cold air hits the side wall of the refrigerated box, a part of the cold air will also be separated. As the cold air sinks, the cold air will flow downward along the gap between the refrigerated air duct component and the box and the gap between the glass shelves, passing through the temperature sensor position, so that the temperature of the temperature sensor quickly reaches the set temperature and the damper is closed. At this time, the temperature sensed by the temperature sensor is inaccurate, and the temperature in the middle of the refrigerated room is still high and has not dropped. Utility Model Content
