In detail, the motor 132 provides power for driving the blower fan 134, and an electric motor generally used may be used. In addition, the blowing fan 134 is mounted on the rotation shaft of the motor 132. The blowing fan 134 may be a centrifugal fan capable of discharging cold air introduced in the rotational axis direction in the circumferential direction, and a turbo fan having excellent blowing ability may be used.

In addition, the motor 132 and the blowing fan 134 are disposed at the center of the fan motor assembly accommodating part 220. The motor 132 on which the blowing fan 134 is mounted may be fixedly mounted to the fan motor assembly accommodating part 220 through a separate mounting member.

The fan motor assembly accommodating part 220 is provided with a shroud 136. The shroud 136 is formed to guide the inflow of cold air into the blowing fan 134 and the cold air discharged from the blowing fan 134.

That is, the shroud 136 accommodates the blowing fan 134 inside, the inlet 137 is opened in the rotation center direction of the blowing fan 134, the cold air flow portion to be described in detail below The discharge port 139 is formed to open in the direction. In addition, the remaining part is shielded and configured to allow the cool air introduced through the inlet 137 to be discharged to the discharge port 139 through the blower fan 134.

The shroud 136 may be mounted to the fan motor assembly accommodating part 220 or may be mounted to the barrier cover 400 to be described below. Of course, if necessary, the shroud 136 may be integrally formed on the barrier cover 400. In addition, the motor 132 coupled with the blowing fan 134 may be fixedly mounted inside the shroud 136.

In addition, cold air guides 222 are further formed at both sides of the fan motor assembly accommodating part 220. The cold air guide part 222 allows the cold air on the evaporator accommodating part 210 to both face the inside of the shroud 136.

It is formed to have the same width as the bottom of. In this case, an upper end of the fan motor assembly accommodating part 220 is formed to have the same width as the discharge port 139 of the shroud 136.

The cold air guide 222 may be formed to be inclined or may have a round shape, and the cold air moved along the cold air guide 222 may be guided into the shroud 136.

Meanwhile, the fan motor assembly accommodating part 220 is formed to be recessed more than the evaporator accommodating part 210 and the cold air flow part 230 to be described below. In this case, the fan motor assembly accommodating part 220 is formed to be spaced apart from the shroud 136. Therefore, the cool air flowing from the evaporator receiver 210 side can be smoothly moved to the inlet 137 side through the spaced space between the fan motor assembly receiver 220 and the shroud 136. do.

Since the evaporator accommodating part 210 and the fan motor assembly accommodating part 220 have different recessed depths, the evaporator accommodating part 210 and the fan motor assembly accommodating part 220 are formed to be stepped with each other. Therefore, the thickness of the heat insulator 300 inside the barrier 100 corresponding to the evaporator accommodating part 210 and the fan motor assembly accommodating part 220 is also different from each other.

In detail, since the evaporator accommodating part 210 is less recessed than the fan motor assembly accommodating part 220, the thickness of the heat insulating material 300 corresponding to the evaporator accommodating part 210 becomes relatively thicker. Therefore, the heat insulation on the side of the evaporator 110 having a lower temperature can be made better.

In addition, since the fan motor assembly accommodating part 220 is more recessed than the evaporator accommodating part 210, the thickness of the heat insulating material 300 corresponding to the evaporator accommodating part 210 becomes relatively thinner.

Therefore, when the fan motor assembly 130 is mounted, it is possible to secure a smooth flow passage of cold air. In addition, although the thickness of the insulation 300 corresponding to the fan motor assembly accommodating portion 220 is relatively thin, the insulation of the fan motor assembly 130 having a relatively higher temperature than that of the evaporator 110 may be obtained. It becomes possible enough.

Meanwhile, the stepped portion of the evaporator accommodating part 210 and the fan motor assembly accommodating part 220 is connected by the connecting part 240. The connection part 240 forms a boundary between the evaporator accommodating part 210 and the fan motor assembly 130 and is formed to be inclined. Therefore, the cool air inside the evaporator accommodating part 210 may be smoothly introduced into the fan motor assembly accommodating part 220.

The cold air flow part 230 is formed above the fan motor assembly accommodating part 220. The cold air flow unit 230 is used to guide the cold air discharged from the discharge port 139 of the shroud 136 to the refrigerating chamber and the freezing chamber 30, and extends to an upper portion of the barrier 100.

The cold air flow part 230 is formed to have a width corresponding to the width of the opened upper end of the fan motor assembly accommodating part 220, or to have a width corresponding to the width of the discharge port 139 of the shroud 136. It can be formed to have.

The cold air flow part 230 is formed to be less recessed than the fan motor assembly accommodating part 220. Therefore, the thickness of the heat insulating material 300 corresponding to the cold air flow part 230 may be formed to be thicker than the heat insulating material thickness corresponding to the fan motor assembly accommodating part 220.

The cold air flow unit 230 forms a cold air flow path by being shielded by the barrier cover 400 to be described below. In addition, a cold air outlet 232 is formed at an upper end of the cold air flow part 230.

The cold air distribution device 140 may be formed as a damper-like structure, and the passage to the cold air outlet 232 is selectively opened and closed. Therefore, when the cold air distribution device 140 is opened, the cold air guided through the cold air flow unit 230 may be discharged to the cold air outlet 232 and introduced into the refrigerating compartment. On the other hand, when the cold air distribution device 140 is closed, the cold air guided through the cold air flow unit 230 is not discharged to the cold air outlet 232 side but discharged only to the freezing chamber 30 side.

Hinckle, the depression 200 is shielded by the barrier cover 400. The barrier cover 400 is formed in a plate shape and shields the recess 200 to form a part of the side surface of the barrier 100, that is, a part of the inner wall surface of the freezing chamber 30.

In the state for supplying cold air to the refrigerating chamber 40, the cold air distribution device 140 is open. Therefore, cold air is discharged to the cold air outlet 232 through the cold air distribution device 140.

The cold air supplied into the refrigerating compartment 40 through the cold air outlet 232 cools the inside of the refrigerating compartment 40, and through the cold air inlet 212 while the blower fan 134 is driven. The cold air of the refrigerating chamber 40 may be circulated while the cold air is introduced again.

Meanwhile, referring to FIG. 9, when the set time is reached during operation of the refrigerator 1, the defrosting operation is started. When the defrosting operation is started, the heat generating member is heated to melt the frost inside the evaporator 110 or the evaporator accommodating portion 210.

The defrost water generated by the defrosting operation flows down to the lower portion of the depression 200 and is collected in the water collecting portion 272 of the drain member 270. The defrost water collected in the water collecting part 272 moves along the inclination of the water collecting part 272 and flows into the connection part 274.

Defrost water flows into the defrost water discharge part 250 connected to the connection pipe 274. Defrost water is discharged to the machine room 50 side through the defrost water discharge unit (250). When the discharge pipe 252 is provided in the defrost water discharge part 250, the defrost water is discharged to the drain pan 56 inside the machine room 50 through the discharge pipe 252.
