Benefits of technology

[0025]According to a refrigerator of the present invention, as a passage for supplying cool air from a freezing chamber to a refrigerating chamber is wholly or partially openable and closable, an actual temperature of the refrigerating chamber can be precisely controlled into a preset temperature. Therefore, stored articles can be freshly maintained to improve users' satisfaction.
[0026]In addition, according to a refrigerator of the present invention, although a plurality of opening and closing blades opened and closed in a sliding direction are installed on a section of a passage through which cool air flows from a freezing chamber to a refrigerating chamber, the opening and closing blades are opened and closed by one motor. As a result, an installation space and a production cost can be considerably reduced due to decrease of the component number.

Problems solved by technology

It is thus difficult to precisely control a temperature of the refrigerating chamber and thus to freshly keep articles stored therein.

first embodiment

[0036]Referring to FIGS. 3 and 4, a damper assembly 50 of the refrigerator according to the present invention includes a mounting portion 51 mounted on a passage through which cool air flows from a freezing chamber F to a refrigerating chamber R, a plurality of opening and closing plates 52a, 52b and 52c hinge-connected to the mounting portion 51, for wholly or partially opening and closing the passage, and a plurality of step motors 53a, 53b and 53c for controlling operations of the opening and closing plates 52a, 52b and 52c. The damper assembly 50 can regulate a flow rate of cool air supplied from the freezing chamber F to the refrigerating chamber R.

[0037]In addition, electric wires 54a, 54b and 54c connected to the step motors 53a, 53b and 53c respectively are connected to a control unit 55 for controlling an operation of the refrigerator, so that an operation of the damper assembly 50 is controlled by the control unit 55. The control unit 55 controls the operation of the dampe...

second embodiment

[0046]A damper assembly 50 of the refrigerator according to the present invention will be described with reference to FIGS. 5 and 6. The damper assembly 50 includes a mounting portion 51 mounted on a passage through which cool air flows from a freezing chamber F to a refrigerating chamber R, a plurality of opening and closing blades 52 formed to slidably move on the mounting portion 51, for wholly or partially opening and closing the passage, and a motor 53 for controlling operations of the opening and closing blades 52. The damper assembly 50 can regulate a flow rate of cool air supplied from the freezing chamber F to the refrigerating chamber R.

[0047]In addition, an electric wire 54 connected to the motor 53 is connected to a control unit 55 for controlling an operation of the refrigerator, so that an operation of the damper assembly 50 is controlled by the control unit 55. The control unit 55 controls the operation of the damper assembly 50 in consideration of a set temperature i...

Abstract

The present invention provides a refrigerator including a passage through which cool air flows from a freezing chamber to a refrigerating chamber, a passage opening and closing member for wholly or partially opening and closing the passage, a driving unit for driving the passage opening and closing member so that the passage opening and closing member can open and close the passage, and a control unit for comparing a set temperature of the refrigerating chamber with a measured temperature of the refrigerating chamber, and controlling an operation of the driving unit according to a comparison result. According to the refrigerator of the present invention, as the passage for supplying the cool air from the freezing chamber to the refrigerating chamber is wholly or partially openable and closable, the actual temperature of the refrigerating chamber can be precisely controlled into the preset temperature. Therefore, stored articles can be freshly maintained to improve users' satisfaction.

Description

TECHNICAL FIELD[0001]The present invention relates to a refrigerator wherein cool air flows from a freezing chamber to a refrigerating chamber, and more particularly, to a refrigerator wherein a flow rate of cool air flowing from a freezing chamber to a refrigerating chamber can be precisely regulated.BACKGROUND ART[0002]FIG. 1 is a view illustrating one example of a conventional refrigerator.[0003]The conventional refrigerator will be described with reference to FIG. 1. The conventional refrigerator includes a refrigerator main body 1 in which a freezing chamber F and a refrigerating chamber R are formed on both sides, and a freezing chamber door (not shown) and a refrigerating chamber door (not shown) installed on the refrigerator main body 1 to be openable and closable, respectively. An insulating material is foam-molded inside of walls of the refrigerator main body 1 and of the doors.[0004]The freezing chamber F and the refrigerating chamber R are separated by a partition wall 2...
