On the other hand, when the external force applied to the second push switch 620 due to the closing of the door 190 is removed (opening of the door 190), the second opening and closing plate 610 is applied to the restoring elastic force of the second spring 630. As shown in FIG. 8, the openings 211 and 221 may be closed again.

Next, with reference to FIGS. 10 and 11, it will be described that the blow control module 700 is operated in accordance with the operation of the opening and closing unit 600 according to the second example.

10 shows the initial position of the opening and closing part 600, Figure 12 shows the operating position.

Referring to FIG. 10, a second detector 722 is installed near the second flow groove 561 according to the present invention. The second sensor 722 may be any one of an ultrasonic sensor, an optical sensor, and a proximity sensor, and serves to detect the second opening / closing plate 610. In addition, the installation position of the second sensor 722 is preferably near the second opening and closing plate 610 is located in the initial position state.

In addition, the second sensor 722 is electrically connected to the first controller 731 and transmits whether the second opening and closing plate 610 is detected in the form of an electrical signal to the first controller 731.

In addition, the first controller 731 is electrically connected to the fan 710 to transmit a control signal for controlling the driving of the fan 710 to the fan 710. Here, the fan 710 may be installed in the freezing region B, which is one end of the cold air supply duct 210, and the fan 710 is the cold air generated in the freezing region B, the cold air supply duct 210. Can be blown to the other end.

When the initial state is achieved as described above, the second sensor 722 detects the second opening / closing plate 610, transmits the detection signal to the first controller 731, and the first controller 731 Since the door 190 is in an open state, the fan 710 may be stopped so that cold air in the freezing region B is not forcedly blown to the outside.

Meanwhile, referring to FIG. 11, when the door 190 is closed to achieve an operating state, the door presses the second push switch 620, and the other end of the second push switch 620 is the second opening / closing plate 610. It is connected to the eccentric to rotate the second opening and closing plate 610. Thus, the second opening and closing plate 610 is out of the sensing area of the second sensor 722.

Accordingly, the second sensor 722 transmits a signal indicating that the second opening / closing plate 610 does not exist to the first controller 731, and the first controller 731 is in a state in which the door 190 is closed. Therefore, the control signal for operating the fan 710 is transmitted to the fan 710 so that the cold air in the freezing region B can be forcedly blown into the ice making chamber 300.

Accordingly, the cold air is supplied into the ice making chamber 300 through the cold air supply duct 210, and the cold air supplied into the ice making chamber 300 is the bottom of the refrigerating area A through the cold air reducing duct 220. Can be discharged.

In addition, a rotation motor 650 is further installed on the rotation shaft 640 of the second opening / closing plate 610, and the rotation motor 650 is electrically connected to the third controller 900 and is provided from the third controller 900. The second opening and closing plate 610 may be rotated to achieve an initial position or an operating position by receiving an electrical signal.

When the defrost mode is preset in the third controller 900 and a signal for selecting the defrost mode is input to the third controller 900 from the outside, the third controller 900 is shown in FIG. 11. In order to seal the openings 211 and 221 of the cold air supply duct 210 and the cold air reduction duct 220, the rotary motor 640 may be operated to rotate the second opening / closing plate 610 to an initial position. .

12 and 13, the present invention may further include a flow path control module.

The flow path control module may be configured to close the cold air supply duct 210 and the openings 211 and 221 of the cold air reduction duct 220 due to the operation of the opening and closing part. The cold air in) may be discharged to the cold air reduction duct 220.

The flow path control module is installed in the connection flow path 230 connecting the cold air supply duct 210 forming the first cold air flow path (①) and the cold air reduction duct 220 forming the second cold air flow path (②). A damper 810 for determining whether the first cold air passage ① and the second cold air passage ② are in communication with each other, a detector for detecting the opening / closing of an end of the cold air passage 200, the detector and the damper The second controller 830 is electrically connected to the 810 and receives a signal for opening / closing the cold air flow passage 200 from the detector and controls the operation of the damper 810.

Here, the detector may be the first sensor 721 or the second sensor 722 described above, the opening and closing plate for opening and closing the openings (211, 221) of the cold air supply duct 210 and the cold air reduction duct 220 is There may be a first opening and closing plate 510 or a second opening and closing plate 610. Therefore, in the following description, the first and second detectors 721 and 722 will be described as sensors, and the first and second open / close plates 510 and 610 will be described as opening and closing plates.

12 shows that the openings 211 and 221 are sealed by the opening and closing plate, which corresponds to the case in which the door 190 is opened.

At this time, the detector detects the opening and closing plate located in the initial position, and transmits a signal for the detected to the second controller 830. In addition, the second controller 830 may transmit an electrical signal to the damper 810, and the damper 810 may open the connection flow path 230. Accordingly, the cold air supply duct 210 and the cold air reduction duct 220 communicate with each other, and the cold air supplied to the cold air supply passage 210 is introduced into the cold air reduction duct 220 through the open connection passage 230. To the refrigeration zone (A).

Therefore, when the door 190 is opened, it is possible to supply the cool air generated in the freezing zone through the cold air reduction duct 220 to the inside of the main body 100 (refrigeration area, A), so that the inside of the main body 100 The problem of temperature rise can be solved.

13 shows the openings 211 and 221 being open, which corresponds to the case in which the door 190 is closed.

At this time, the detector detects that the opening and closing plate deviates from the initial position, and transmits a signal for the detected to the second controller 830. In addition, the second controller 830 may transmit an electrical signal to the damper 810, and the damper 810 may close the connection flow path 230. Accordingly, the cold air supply duct 210 and the cold air reduction duct 220 form an independent flow path in a state where they cannot communicate with each other, and the openings 211 and 221 of each of the ducts 210 and 220 are formed in the ice making chamber 300. It is connected to the connection holes (311, 312).
