However, in recent years, refrigerators tend to increase the actual capacity that can be stored by devising the arrangement of the components of the refrigerator.

The container provided in the conventional drawer-type storage chamber is only placed on the rail device. If the internal volume of the container increases in this manner, the amount of items stored in the container increases and the load on the rail device also increases. When the drawer door is opened, a larger load is applied to the rail device, and in particular, stress applied to the end portion of the rail device, which is an attachment portion between the rail device and the drawer door, increases.

Also, due to an increase in the load applied to the rail device, the rail device may be deformed and fall inward. In such a state, the drawer door cannot be moved smoothly back and forth.

This is because only the rail device 202 supports the container 206 interlocked with the opening of the drawer door when the drawer door is fully opened. Furthermore, since the drawer door thermally insulated and foamed inside is at the end of the rail device 202, the load of the drawer door 201 is applied to the end of the rail device 202 in addition to the load of the container 206. Further, there is a case where a vacuum heat insulating material is embedded in the drawer door 201 from the viewpoint of energy saving, and the load on the rail device 202 is increased. For this reason, the rail device 202 is deformed by repeating the opening / closing operation of the drawer door 201 over a long period of time, so that even if the drawer door 201 is brought into contact with the opening of the vegetable compartment 103 or the freezing compartment 104, Since the drawer door 201 is distorted, the opening portion cannot be completely closed, or the opening portion cannot be sealed with a seal portion (not shown) of the drawer door 201, and the indoor cold air is generated. There is a risk that it may leak and cannot be cooled to a predetermined temperature.

The present invention solves the above-described conventional problems, and is a refrigerator having a drawer-type storage chamber, which distributes the load applied particularly to the rail device while ensuring a large actual storage capacity in the drawer-type storage chamber.

It is possible to compensate for insufficient strength of the attachment portion between the rail device 202 attached to the lower portion and the drawer door 201, and to smoothly open and close the drawer door.

That is, since the moment applied to the mounting portion is reduced, the mounting portion of the top rail 203 or the mounting portion of the rail fixing portion can be protected from damage. That is, in the present embodiment, the front flange 206a of the container 206 is fixed to the drawer door 201 provided with the first fixing means 301 and / or the second fixing means 303, and the rear protrusion 206c of the container 206 is further connected to the door. By inserting and fixing in the fixing hole 205 b provided in the frame 205, the position serving as a fulcrum of the pulling force can be set behind the drawer door 201.

Next, as shown in FIG. 9, a rail mounting portion 223 formed integrally with the cabinet rail 222 is disposed so as to come into contact with the side of the inner box 110 on the surface, and a screw 400 is provided on the side of the inner box 110. Fixed.

At this time, since the inner box 110 serving as a mounting surface is mainly molded from resin, even if screws are directly fixed to the inner box 110, it is not possible to secure a strength that can withstand the load applied to the rail device 202. Therefore, as a means for securely fixing the rail device 202, the rail device 202 is attached to the rail holding member 270 embedded in the heat insulating material 111 via the inner box 110.

The rail holding member 270 is mainly formed of a metal material such as iron. Further, by fixing the rail holding member 270 in a predetermined position on the inner surface of the inner box 110 in advance, and then filling the space between the inner box 110 and the outer box 112 with the foam heat insulating material and burying it in the heat insulating material 111, The holding force of the rail holding member 270 can be further improved.

Specifically, in the case of the freezer compartment 104 that is formed at a substantially central position in the layout of the refrigerator 100, the rail holding member 270 is arranged on the upper part of the partition wall 108 that partitions the vegetable compartment 103 arranged in the lower part.

Further, part A is a perspective view in which a rail device 202 for holding the container 206 of the freezer compartment 104 and a rail holding member 270 are disposed in the inner box 110, and will be described with reference to FIG. Part B is a perspective view in which the rail device 202 for holding the container 206 of the vegetable compartment 103 and the rail holding member 280 are disposed in the inner box 110, and will be described with reference to FIG.

As shown in FIG. 10, the rail holding member 270 integrally includes a rail mounting portion 223 of the rail device 202 and a rail holding portion 270 a fixed by a screw 400 and an inward fall prevention means 270 b for preventing the rail device 202 from falling inward. The inward fall prevention means 270b formed is a lateral flange portion formed integrally with the lower portion of the rail holding portion 270a disposed in close contact with the inner box 110.

Specifically, the inward fall prevention means 270b moves away from the inner box 110 from the lower part of the rail holding part 270a, which is a vertical flange portion formed so as to be in close contact with the inner box 110 from the heat insulating material 111 side, and is directed toward the outer box 112. It is formed by bending to the bottom and further bent downward. Then, since the horizontal flange portion of the inclining prevention means 270b receives the heat insulating material 111 on the surface of the filled heat insulating material 111, and the horizontal flange bites into the heat insulating material, the rail holding portion 270a is moved by the inward falling prevention means 270b. It is fixed, the strength of the rail holding member 270 can be secured, the rail mounting portion 223 can be prevented from falling into the inside of the freezer compartment, and the rail device 202 can be prevented from falling down toward the inside of the freezer. 201 can be opened and closed smoothly.

Further, the inward fall prevention means 270b of the horizontal flange part may be bent integrally from the lower part of the rail holding part 270a, and the inward fall prevention means 270b may be formed on both the upper part and the lower part. As a result, the upper and lower horizontal flange portions receive heat insulating material 111 on the surface with respect to the rail holding portion 270a, and the upper and lower horizontal flange portions bite into the heat insulating material, thereby further ensuring the strength of the rail holding member 270. It is possible to prevent the rail mounting portion 223 from falling to the inside of the freezer compartment, and to prevent the rail device 202 from falling in the direction of the inside of the refrigerator.

In FIG. 10, the partition wall 108 serving as the bottom wall of the freezer compartment 104 has bottom surface step portions 108 a formed on both sides, and the bottom surface step portion 108 a is one step higher than the central portion serving as the reference surface of the partition wall 108 in the depth direction.

The rail mounting portion 223 is fixed with a metal rail holding member 270 and a screw 400 with the side surface step portion 110a interposed therebetween.

Therefore, since the rail device 202 is placed on the bottom stepped portion 108a and fixed to the side stepped portion 110a with screws, the rail device 202 jumping out into the storage space can be suppressed, and the full width of the container 206 in the freezer compartment 104 can be suppressed. The dimensions can be increased and the invalid space can be reduced.

Also, since the rail device 202 is assembled by being placed on the bottom stepped portion 108a, workability can be improved. Moreover, since the wall thickness of the partition wall 108 becomes large in the bottom stepped portion 108a, the metal rail device 202 in the freezer compartment 104 is cooled, and the partition wall 108 that becomes the top surface of the vegetable compartment 103 in the lower part. Can be prevented from condensing.

Further, since the bottom surface step portion 108a is provided, the rail device 202 does not come into contact with the dew condensation water even when the dew condensation water collects in the central portion serving as the reference surface of the partition wall 108. For this reason, dew condensation water does not freeze and the rail apparatus 202 does not adhere. Thereby, the drawer door 201 can be opened and closed smoothly.

Also, a door frame 205 fixed with screws is formed on the upper surface of the top rail 203 of the rail device 202, and a stepped portion 262 of the container 206 is placed on the upper surface of the door frame 205.

Moreover, as shown in FIG. 11, the rail holding member 280 of the vegetable compartment 103 formed in the lowermost part is disposed in the heat insulating material 111.

Accordingly, since the rail device 202 is placed on the bottom surface step portion 401 a and fixed to the side surface step portion 110 a with screws, the rail device 202 jumping out into the storage space can be suppressed, and the full width of the container 206 in the vegetable compartment 103. The dimensions can be increased and the invalid space can be reduced.

Also, since the rail device 202 is assembled by being placed on the bottom surface step 401a, workability can be improved. Moreover, since the wall thickness of the bottom face wall 401 becomes large at the bottom step portion 401a, heat insulation can be secured.

Furthermore, since the bottom surface step 401a is provided, the rail device 202 does not come into contact with the dew condensation water even when the dew condensation water accumulates in the central portion serving as the reference surface of the bottom wall 401. For this reason, dew condensation water does not freeze and the rail apparatus 202 does not adhere. Thereby, the drawer door 201 can be opened and closed smoothly.

In addition, the drawer door 201 of the lowermost vegetable compartment 103 is located below the drawer door 201 of the upper freezer compartment 104, and when the user pulls out the drawer door 201, the drawer of the vegetable compartment 103 at the lowermost position is positioned. The door 201 is located at a position where it is easy to put weight on it, and an external load may be applied in addition to the load of the storage amount, and the rail holding member 280 is prevented from falling down to become a substantially L-shaped rail holding portion 280a and a lower flange portion. Since the means 280b is integrally formed, it is possible to keep the rail device 202 of the lowermost drawer door 201 from falling down more firmly.

Furthermore, since the horizontal flange provided in the rail holding member 280 of the vegetable compartment 103 is wider than the horizontal flange provided in the rail holding member 270 of the upper freezer compartment 104, The rail device 202 can be kept stronger as a fall prevention.

In addition, since both the freezer compartment 104 and the vegetable compartment 103 have the side wall thickness reduced by the side stepped portion 110a, a vacuum heat insulating material (not shown) is made to correspond to the portion where the rail device 202 is disposed. The heat insulation can be ensured by attaching a vacuum heat insulating material having a height dimension larger than that between the rail device 202 of the freezer compartment 104 and the vegetable compartment 103 to the outer box 112.

As described above, the rail device 202 is fixed to the rail holding member 270 and the side wall only by the screw 400, but the rail device 202 of the freezer compartment 104 is placed on the partition wall 108 and is held by the rail mounting portion 223.
