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.

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.

8 and 9, inside the refrigerating chamber 30, cold air discharged from the cold air outlet 232 flows into the cold air inlet 212 and circulates in the refrigerating chamber 30.

Some of the air circulated in the refrigerating chamber 30 moves along the wall surface of the barrier 100. At this time, the cold air moving along the barrier 100 is separated from the condensation preventing part 500.

In detail, the air passing through the condensation preventing part 500 is separated from the inlet of the heat insulating groove 520 of the condensation preventing part 500, and part of the air moves to the inside of the heat insulating groove 520. As described above, some of the cold air separated at the inlet of the heat insulating groove 520 proceeds in the advancing direction and becomes excessively over the heat insulating groove 520, and the other part is introduced into the heat insulating groove 520.

The cold air introduced into the heat insulating groove 520 moves along the inner wall surface of the heat insulating groove 520. That is, the inlet of the insulating groove 520 is moved in order from the side wall and the bottom and the opposite side wall.

As such, the inside of the insulating groove 520 is caused to recycle the incoming cold air. Therefore, the air condensation prevention part 500 is provided with an air layer corresponding to the depth of the heat insulation groove 520. In addition, recirculation of cold air occurs in all of the plurality of heat insulating grooves 520 formed in the condensation preventing part 500, and a heat insulating layer is formed in the condensation preventing part 500 to prevent heat exchange.

In detail, an air layer is formed between the surface of the barrier 100 and the inside of the refrigerating chamber 30 by the cold air recirculated in the heat insulating groove 520. In addition, the air inside the refrigerating chamber 30 is not directly heat-exchanged with the surface of the barrier 100 by the air layer.

That is, by preventing the mixing between the surface temperature of the barrier 100 and the air in the refrigerating chamber 30, the heat transfer rate of the surface of the barrier 100 is lowered. Therefore, condensation does not occur on the surface of the barrier 100 even at a position corresponding to the fan motor assembly accommodating portion 220 having a relatively thin thickness of the heat insulating material 300.
