Fixed cover according to the invention is characterized in that it is installed in the freezer compartment or the refrigerating compartment of the refrigerator body.

The inner case according to the present invention is characterized in that the slot guide is inserted into the fixing cover is formed.

The fixing cover according to the present invention includes a coupling plate inserted into the slot guide, an accommodating groove portion located in the center of the coupling plate and protruding outward, and the accommodating groove portion so that the temperature sensor is positioned on the accommodating groove portion. It is configured to include a partition wall partitioned into an area of.

The coupling plate of the fixing cover according to the present invention is characterized in that a wire groove for stably received toward the outside of the coupling plate is formed by the wire of the temperature sensor via the accommodation groove.

The partition wall of the fixing cover according to the present invention is spaced apart from the outside of the temperature sensor, characterized in that formed on the receiving groove portion.

The partition wall of the fixing cover according to the present invention is characterized in that the holder is provided to enable fixing the position of the temperature sensor.

The holder of the fixing cover according to the present invention is characterized in that the engaging piece is formed to prevent separation when the temperature sensor is coupled.

The holder of the fixing cover according to the present invention is characterized by extending along the longitudinal direction of the partition wall.

As described above, the temperature sensor fixing cover for a refrigerator according to the present invention has the effect of preventing the variation of the position sensor due to the high pressure foam liquid in the state in which the temperature sensor is installed on the inner case.

In addition, since the temperature sensor is fixed at the initial installation position, the temperature of the refrigerating compartment or the freezing compartment is stably detected at the initially set position, enabling efficient operation of the entire refrigerator, thereby preventing unnecessary power consumption, thereby reducing the economic burden on the consumer. There is an effect that can reduce.
