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

First, referring to FIG. 4, the cabinet 11 of the refrigerator 10 according to the embodiment of the present invention is provided with a refrigerator compartment 111, a freezer compartment 112, and a multipurpose room 113 as described above. Then, the refrigerating chamber 111 is disposed adjacent to the upper side of the multi-purpose chamber 113, and the refrigerating chamber 111 and the multi-purpose chamber 113 are partitioned by the first mullion 115. Then, the freezer compartment 112 is disposed adjacent to the lower side of the multipurpose room 113, and the freezer compartment 112 and the multipurpose room 113 are partitioned by a second mullion 116.

In addition, a plurality of shelves 111a may be disposed up and down to place food or containers inside the refrigerating chamber 111, and one or a plurality of storage boxes 111b capable of storing food and the like are provided. .

Meanwhile, 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 extends to a length corresponding to the width of the first mullion 115 and may form a predetermined width toward the rear side of the refrigerator compartment 111. The width of the access hole 115a may be equal to or less than the width of the refrigerating space 152 of the storage box 155. In addition, the length of the access hole 115a extending in the left and right directions may also be formed to be equal to or less than the length of the storage box 155 in the left and right directions of the refrigerating space 152.

In addition, the access cover 16 is made of a transparent material, so that the contents stored in the refrigerating 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 an insulating function. This is because it is necessary to maintain the refrigerating space 152 at the refrigerating temperature by exchanging heat between the refrigerating compartment 111 and the refrigerating space 152 by heat conduction through the access cover 16. When the refrigerating chamber 111 is a refrigerating chamber, the refrigerating space 152 will be maintained at a refrigerating temperature by heat conduction through the access cover 16. Of course, when the access cover 16 is moved rearward and the access hole 115a is opened, cold air inside the refrigerating compartment 111 will be transferred to the refrigerating space 152 by convection.

Meanwhile, the access cover 16 includes a cover body 161 forming an edge area, a glass panel 162 formed inside the cover body 161, and an upper surface of the front end of the cover body 161. It may include a handle 163 is formed. The access cover 16 is not necessarily made of a glass material, but may be made of a transparent plastic material. For example, a transparent plastic panel coated with an opaque color at the edge is also possible.

In detail, sliding grooves 115b are formed at both side edges of the access hole 115a so that both side edges of the access cover 16 are inserted, so that the access cover 16 slides in the front-rear direction. Thereby, the access hole 115a can be selectively opened and closed. In addition, a cover receiving groove 115c (refer to FIG. 6) is formed inside the first mullion 115 to accommodate the access cover 16 slidingly moved to the rear.

Alternatively, the access cover 16 may also be rotatably coupled to the first mullion 115 like the cover member 154. That is, after the rear end of the access cover 16 is rotatably connected to the first mullion 115, the user holds and lifts the handle 163 of the access cover 16, and then the storage box 155 ) May be taken out of food stored in the refrigerated space 152 or stored in the refrigerated space 152 of the storage box 155.

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

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

In detail, a cold air outlet and a cold air recovery port are respectively formed on the cold air grill 201, and the cold air discharge port and the cold air recovery port are provided at a cold air discharge port 155c and a cold air recovery port 155d formed on the rear surface of the storage box 155. It comes in close contact. Therefore, the cold air of the sub-evaporation chamber 113a communicates only 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 a freezing temperature by cold air supplied from the sub-evaporation chamber 113a. In addition, the cold air of the sub-evaporation chamber 113a, the cold air grill 201 only when the storage door 15 moves forward and the rear surface of the storage box 155 is separated from the cold air grill 201. ) Is discharged into the front space 113c.

In addition, in the state in which the storage door 15 is completely in close contact with the front surface of the cabinet 11, the access hole 115a formed in the first mullion 115 is a refrigeration space of the storage box 155 ( 152) It is located on the upper side. In addition, the access hole 115a may be closed by the access cover 16, or the access hole 115a may be opened by the access cover 16 retracting. If, in the state in which the access hole 115a is closed by the access cover 16, the cold air in the refrigerating compartment 111 is transferred to the refrigerating space 152 by a heat conduction phenomenon, and the access hole 115a In this open state, the cold air of the refrigerating chamber 111 is directly transferred to the refrigerating space 152. Here, since the opened upper surface of the freezing space 153 is kept closed by the cover member 154, the cold air in the refrigerating chamber 111 is not transmitted to the freezing space 153, but also the freezing Cold air inside the space 153 is not delivered to the refrigerating space 152 or the refrigerating chamber 111.

In addition, the cover member 154 may open the freezing space 153 by sliding in the front-rear direction only when the storage box 155 is pulled out. If, when the cover member 154 is sliding to the rear of the storage box 155 to close the storage door 15 in the state where the freezing space 153 is open, from the rear of the storage box 155 The cover member 154 protruding to the rear is caught in the cold air grill 201 and cannot move. In addition, the freezing space 153 is automatically closed by the cover member 154 in the process of moving backward until the storage box 155 is in close contact with the cold air grill 201. Therefore, when the storage door 15 is completely closed, the freezing space 153 is always kept closed by the cover member 154. Therefore, the cold air supplied to the freezing space 153 does not pass to the refrigerating space 152, and the thickness of the insulating wall defining the freezing space 153 is thicker than the insulating wall of the refrigerating space 152. By doing so, it is possible to minimize the phenomenon in which the refrigerating space 152 is supercooled by cold air and heat exchange in the freezing space 153.

Meanwhile, the freezer compartment 112 may be a freezer compartment, and a freezer drawer 142 may be mounted on a rear side of the freezer door 14. As mentioned above, the freezer compartment 112 may be configured to accommodate a drawer-shaped storage member as in the multipurpose room 113. In addition, a cold air grill 202 is formed at the rear of the freezing chamber 112, and a rear space of the cold air grill 202 may be a main evaporation chamber 112a. In addition, the main evaporator 21 and the main fan 22 may be installed in the main evaporation chamber 112a.

Here, in addition to the structure in which an independent sub-evaporation chamber 113a is formed on the rear side of the multi-purpose chamber 113, the cooling of the main evaporation chamber 112a through the second mullion 116 refrigerates the storage box 155. It would also be possible to have it delivered to space 153. Then, since the sub-evaporator 123 and the sub-fan 124 are unnecessary, an effect of reducing manufacturing cost can be obtained.

Meanwhile, the refrigerating chamber 111 may be defined as a first storage chamber, the multipurpose chamber 113 may be defined as a second storage chamber, and the freezing chamber 112 may be defined as a third storage chamber. In addition, the main evaporation chamber 112a and the sub evaporation chamber 113a may be defined as cooling chambers in which evaporators are installed.
