Installing method for refrigerator and its temperature sensor

Abstract

A direct cooling type refrigerator controlling the temperature thereof, reducing the ON / OFF time of its compressor, thereby preventing the temperature deviation of its storage compartment from increasing over a predetermined value. The refrigerator includes an outer casing defining an appearance of the refrigerator, an inner casing arranged within the outer casing, and defined with a storage compartment, an insulator interposed between the outer casing and the inner casing, a compressor for compressing a refrigerant, an evaporator arranged to be in contact with the inner casing, and adapted to cool the inner casing in accordance with evaporation of a refrigerant passing therethrough, a temperature sensor provided with a surface contact area closely contacting the inner casing, and adapted to sense a temperature of the inner casing, and a control unit for controlling the compressor in accordance with the temperature sensed by the temperature sensor.

Description

technical field [0001] The invention relates to a direct-cooling refrigerator, in particular to a direct-cooling refrigerator in which the contact area between the inner housing forming the storage room and the temperature sensor is large, so that the temperature change of the storage room can be correctly and quickly sensed and the compressor can be controlled. How to install a refrigerator and its temperature sensor. Background technique [0002] In general, refrigerators are classified into two types according to their cooling methods. That is, a direct cooling type refrigerator that cools the storage room by directly cooling the inner case of a storage room forming a freezer or a refrigerating room using an evaporator, and a cooling fan that supplies cold air generated by heat exchange with the evaporator to the storage room Indirect refrigerator. [0003] Such as figure 1 As shown, a common direct-cooling refrigerator includes an outer casing 2 forming the outer shap...

Problems solved by technology

[0010] However, in the above-mentioned direct-cooling refrigerator of the prior art, the electrothermal component 16 of the aforementioned temperature sensor is in line contact with the inner casing 4, so it takes a certain amount of time for the heat of the aforementioned inner casing 4 to be transferred to the electrothermal component 16 of the temperature sensor. The on / off of the compressor 8 cannot be quickly controlled according to the temperature change of the storage room F. In addition, because a part of the electric heating component 16 of the aforementioned temperature sensor is easily in poor contact with the aforementioned internal housing 4, there is a deterioration in the temperature sensing performance, and the sensing temperature big change

[0011] And, in the direct cooling type refrigerator of above-mentioned prior art, the electrothermal component 16 of aforementioned temperature sensor is fixed on the aluminum strip 19, and aforementioned aluminum strip 19 is fixed on inner housing 4, so the electrothermal component 16 of aforementioned temperature sensor is installed Strong, external collisions, etc. are likely to cause poor contact between the electric heating component 16 of the temperature sensor and the inner casing 4
