The first coupling part 132 may be projected downward from a lower surface of the first cover main body 131, and the second coupling part 149 may be inserted between one portion of the first cover main body 131 and the first coupling part 132. The second cover 140 may include a second cover main body 141 having a rectangular panel shape, corresponding to a shape of the first cover main body 131, a guide surface 146 which is provided in an upper portion of the second cover main body 141 and guides the flow of cooling air discharged from the outlet port 72, and a plurality of ribs 143 provided on one side of the guide surface 146.


The guide surface 146 may form a flat upper surface of the second cover main body 141 and the plurality of ribs 143 may be provided to protrude upward from the upper surface of the second cover main body 141. The plurality of ribs 143 may be provided at a front of the outlet port 72, and the guide surface 146 may be provided at a side of the plurality of ribs 143. The plurality of ribs 143 may serve as a blocking part which relatively blocks the flow of the cooling air discharged from the outlet port 72. The cooling air may bypass the plurality of ribs 143, and may flow toward the guide surface 146.


If the cooling air discharged from the outlet port 72 flows straight forward and then is immediately introduced into the drawer main body 110, the cooling air may not be circulated in the storage space 111 of the drawer main body 110, and instead may be immediately discharged through an inlet port 114 of the drawer main body 110. By providing the plurality of ribs 143, the cooling air does not flow straight forward, but may be introduced in a predetermined arc into the drawer main body 110.


An insulator 129 may be provided for preventing condensation caused by the cooling air path 120a in the second cover 140. The insulator 129 may be provided on an upper side of the second cover main body 141, and may be arranged on an upper side of the cooling air path 120a at the locations corresponding to the cooling air path 120a. When the insulator 129 is provided, the condensation and dew resulting from the inside and outside temperature difference of the cooling air path 120a may be prevented.


Referring to FIGS. 5 to 9, the inlet port 114 may be formed on a rear surface of the drawer main body 110. A suction guide 110a which guides the flow of cooling air that flows into the inlet port 114 may be provided in front of the inlet port 114. Cooling air of a first space part (or first space) 111a may be sucked into the inlet port 114 through the suction guide 110a and flow to the evaporator.

The first space part 111a may be defined by the drawer main body 110 and divider 200, and may be a space that may communicate with the outside through the inlet port 114. That is, a seating part (or seat) 113a on which the inlet port 114 and the fan housing 70 are installed may be formed in the rear surface of the drawer main body 110 defining the second space part 111b.


The second cover 140 may include a communication part (or communication port) 148 guiding the cooling air which is flowing in the cooling air path 120a to flow into the interior of the drawer main body 110. The communication part 148 may be an inlet hole in which at least a portion of the second cover main body 141 is cut and which introduces the cooling air into the storage space 111 of the drawer main body 110. The communication part 148 may also be formed between the guide surface 146 forming the cooling air path 120a and one surface of the second cover 140 forming the air bound 120b.


The second cover 140 may further include a stepped part (or step) 147 which is formed to be stepped downward from the guide surface 146. The stepped part 147 may be configured to extend toward the communication part 148 from the guide surface 146. The communication part 148 may be formed on one end of the stepped part 147, and may be placed adjacent to one side of the coupling parts 132 and 149.


Cooling air flowing along the guide surface 146 may pass the stepped part 147, flow downward by switching a flow direction, and may be inserted into the storage space 111 of the drawer main body 110 via the communication part 148. According to the configuration, while the cooling air discharged from the outlet port 72 passes through the guide surface 146, the stepped part 147, and the communication part 148, the flow direction may be switched so that the cooling air may be introduced into the storage space 111 of the drawer main body 110. Since the guide surface 146, the stepped part 147, and the communication part 148 may cause the cooling air to flow toward the center of the drawer main body 110 from a side of the drawer main body 110, the cooling air may be effectively circulated through the entire area of the storage space 111.


Seating parts 113a and 113b which are recessed in a predetermined direction may be formed at the rear surface of the drawer main body 110. Specifically, the seating parts 113a and 113b may include a first seating part (or first seat) 113a which supports at least a part of the fan housing 70, and a second seating part (or second seat) 113b on which a temperature sensor 180 may be seated.

The inlet port 114 may be formed at a lower side of the seating parts 113a and 113b. The seating parts 113a and 113b may be formed in a rear upper portion of the drawer main body 110, and the inlet port 114 may be formed in a rear lower portion of the drawer main body 110.


Since the seating parts 113a and 113b may be formed with the rear surface of the drawer main body 110, the cooling air in the first space part 111a may circulate smoothly. Specifically, the drawer main body 110 may include a rear surface, a lower surface and first and second side surfaces. Cooling air may flow into the cooling air duct 120 through the rear surface and may be inserted into the first space part 111a via the communication part 148. In this process, the cooling air may flow toward the divider 200 and may circulate throughout the first space part 111a. The cooling air circulated in the first space part 111a may then flow toward the rear surface of the drawer main body 110 and may be released from the drawer main body 110 through the inlet port 114.


The divider 200 dividing the storage space 111 may be provided in the drawer main body 110. The divider 200 may divide the storage space 111 into a left and a right.
