Hereinafter, the multi-function room door 15 is defined as a storage door 15.

The storage box 155 is partitioned into a refrigerating space 152 and a freezing space 153 by a partition wall 155a and the refrigerating space 152 may be located in front of the freezing space 153. [ The open upper surface of the freezing space 153 is covered with a cover member 154 made of a transparent material. In detail, the cover member 154 may be a tempered glass or a transparent plastic having an insulating function. A slide groove 155b is formed in the front side of the freezing space 153 and a slide rib 154a is protruded on both sides of the cover member 154. [ The slide rib 154a is inserted into the slide groove 155b so that the cover member 154 slides in the forward and backward directions to selectively open and close the upper opening of the freezing space 153. [ A handle 154b may be formed on the upper surface of the front end of the cover member 154 to protrude or sink.

Meanwhile, the cover member 154 may be coupled to the storage box 155 so as to be vertically rotatable about the rear end of the cover member 154 as a center of rotation. That is, the rear end of the cover member 154 may be rotatably coupled to the rear upper end of the storage box 155. According to this structure, after the storage box 155 is drawn out to the maximum extent from the multi-use chamber 113, the handle 154b of the cover member 154 is lifted up and the contents Or take out the food.

A cool air discharge port 155c and a cool air recovery port 155d are formed on the rear surface of the storage box 155 corresponding to the rear surface of the freezing space 153 so that a sub evaporation chamber 113a ).

A setting button for setting the temperature of the refrigerating space 152 and the freezing space 153 may be provided on the upper surface of the receiving door 15, And a control panel 156 including a display unit for displaying the temperature of the freezing space 152 and the freezing space 153 may be provided.

In the freezing chamber 112, a storage drawer having slide rails can be attached to both sides of the freezing chamber 112 in the same manner as the multi-use chamber 113. A rail guide 112b, 4) is provided so that the storage drawer can be slidably moved in the front-rear direction.

The wall thickness of the storage box 155 forming the freezing space 153, that is, the thickness of the heat insulating layer is formed thicker than the wall thickness of the refrigerating space 152, It is possible to prevent the refrigerating space 152 from being subcooled.

4 and 5 are perspective views showing an internal structure of a refrigerator cabinet provided with an access cover according to an embodiment of the present invention.

4, the cabinet 11 of the refrigerator 10 according to the embodiment of the present invention includes the refrigerating chamber 111, the freezing chamber 112, and the multi-use chamber 113, as described above. The refrigerating chamber 111 is disposed adjacent to the upper side of the multi-use chamber 113 and the refrigerating chamber 111 and the multi-room 113 are partitioned by the first mullion 115. The freezing chamber 112 is disposed adjacent to the lower side of the multi-use chamber 113 and the freezing chamber 112 and the multi-use chamber 113 are partitioned by the second mullion 116.

A plurality of shelves 111a may be arranged vertically so that food or containers can be placed on the inside of the refrigerating chamber 111 and one or a plurality of storage boxes 111b capable of storing foods or the like are provided .

On the other hand, an access hole 115a (see FIG. 5) is formed in front of the first mullion 115, and the access hole 115a is selectively opened and closed by the access cover 16.

In detail, the access hole 115a may have a length corresponding to the width of the first mullion 115 and may have a predetermined width on the rear side of the refrigerating chamber 111. [ The width of the access hole 115a may be equal to or smaller than the width of the refrigerating space 152 of the storage box 155. The length of the access hole 115a in the left-right direction may be the same as or smaller than the length of the storage box 155 in the left-right direction of the refrigerating space 152.

The access cover 16 is made of a transparent material so that the contents stored in the refrigerated space 152 of the storage box 155 can be checked. Here, unlike the cover member 154, the access cover 16 may not be a material having a heat insulating function. This is because it is necessary to heat-exchange the refrigerating compartment 111 and the refrigerating space 152 by heat conduction through the access cover 16 to keep the refrigerating space 152 at the refrigerating temperature. When the refrigerating compartment 111 is a refrigerating compartment, the refrigerating compartment 152 is maintained at a refrigerating temperature by the heat conduction through the access cover 16. Of course, when the access cover 16 moves rearward and the access hole 115a is opened, the cold air inside the refrigerating chamber 111 will be transferred to the refrigerating space 152 by convection.

On the other hand, the access cover 16 includes a cover body 161 forming a rim region, a glass panel 162 formed inside the cover body 161, and an upper surface of the front end portion of the cover body 161 And may include a handle 163 formed therein. The access cover 16 is not necessarily made of a glass material, but may be made of a transparent plastic material. For example, transparent plastic panels coated with opaque colors at the edges are also possible.

More specifically, the access holes 115a are formed with sliding grooves 115b at both side edges thereof so that both side edges of the access cover 16 are inserted, so that the access cover 16 slides in the front-rear direction The access hole 115a can be selectively opened and closed. A cover receiving groove 115c (see FIG. 6) is formed in the first mullion 115 so as to accommodate the access cover 16 slid rearward.

Alternatively, the access cover 16 may be pivotally coupled to the first mullion 115, like the cover member 154. That is, the rear end of the access cover 16 is rotatably connected to the first mullion 115 so that when the user holds the handle 163 of the access cover 16 and lifts it, the storage box 155 Or the food can be stored in the refrigerated space 152 of the storage box 155. [0042] In addition,

6 is a longitudinal sectional view of a refrigerator according to an embodiment of the present invention.

6, the multi-room 113 is divided into two spaces by a cool air grill 201. The front space 113c is a space in which the storage box 155 is accommodated, The space forms a sub evaporation chamber 113a. A sub-evaporator 23 and a sub-fan 24 are installed in the sub-evaporation chamber 113a so that the cooling of the multi-utilization chamber 113 can be independently controlled.

The cold air discharge port and the cold air recovery port are formed in the cold air discharge port 155c and the cold air recovery port 155d formed on the rear surface of the storage box 155, . Therefore, the cold air in the sub evaporation room 113a communicates with the freezing space 153 of the storage box 155 through the cold air discharge port 115c and the cold air recovery port 155d. That is, the freezing space 153 is maintained at the freezing temperature by the cool air supplied from the sub evaporation chamber 113a. The cool air in the sub evaporative chamber 113a is supplied to the cool grill 201 only when the storage door 15 is moved forward and the rear surface of the storage box 155 is separated from the cool grill 201 To the front space 113c.

The access hole 115a formed in the first mullion 115 is inserted into the refrigerating space of the storage box 155 in a state in which the storage door 15 is completely in contact with the front surface of the cabinet 11. [ 152, respectively. The access cover 115 may be closed by the access cover 16 or the access cover 16 may be retreated to open the access hole 115a. In the state that the access hole 115a is closed by the access cover 16, the cold air in the refrigerating chamber 111 is transferred to the refrigerating space 152 due to the heat conduction phenomenon, The cold air in the refrigerating chamber 111 is directly transferred to the refrigerating space 152. In this case, Since the opened upper surface of the freezing space 153 is kept closed by the cover member 154, the cold air in the freezing chamber 111 is not transferred to the freezing space 153, The cold air in the space 153 is not transferred to the refrigerating space 152 or the refrigerating chamber 111.

In addition, the cover member 154 can slide in the front-rear direction only when the storage box 155 is drawn out to open the freezing space 153. If the cover member 154 slides rearward of the storage box 155 and the storage door 15 is closed while the freezing space 153 is opened from the rear side of the storage box 155, The cover member 154 protruding rearward is caught by the cold grill 201 and can not move. The freezing space 153 is automatically closed by the cover member 154 in a process of moving backward until the storage box 155 is brought into close contact with the cold grill 201. Therefore, when the storage door 15 is completely closed, the freezing space 153 is always kept closed by the cover member 154. The cold air supplied to the freezing space 153 does not flow into the refrigerating space 152 and the thickness of the heat insulating wall defining the freezing space 153 is thicker than the heat insulating wall of the refrigerating space 152 Thereby minimizing a phenomenon in which the refrigerating space 152 is overcooled by heat exchange with the cold air in the freezing space 153.

Meanwhile, the freezing chamber 112 may be a freezing chamber, and a freezing chamber drawer 142 may be mounted on a rear surface of the freezing chamber door 14. [ As described above, the freezing chamber 112 can be configured to receive a drawer-shaped receiving member like the multi-function chamber 113. A cold grill 202 may be formed on the rear side of the freezing chamber 112 and a space on the rear side of the cold grill 202 may be a main evaporation chamber 112a. A main evaporator 21 and a main fan 22 may be installed in the main evaporation chamber 112a.

In addition to the structure in which the separate sub evaporation chamber 113a is formed on the rear side of the multi-use chamber 113, the cool air in the main evaporation chamber 112a is frozen in the storage box 155 through the second mullion 116 It is also possible to transmit the information to the space 153. This eliminates the need for the sub-evaporator 123 and the sub-fan 124, thereby reducing the manufacturing cost.

Meanwhile, the refrigerating chamber 111 may be defined as a first storage chamber, the multi-use chamber 113 may be defined as a second storage chamber, and the freezing chamber 112 may be defined as a third storage chamber. The main evaporation chamber 112a and the sub evaporation chamber 113a may be defined as a cooling chamber in which an evaporator is installed, respectively.
