The structures of the rails are positioned symmetrically on the flanges 10a of the receiving case 10 and a rail member between the side wall 3 of an inner box and the receiving case becomes unnecessary whereby the width of the receiving case can be enlarged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a refrigerator, and more particularly to a refrigerator having a device for pulling out a storage case inside the refrigerator.

[Prior Art] As described in Japanese Unexamined Patent Publication No. 64-6688, a conventional device has a rail structure in which a steel plate rail member is constructed between a refrigerator inner box and a storage case, which requires a space. It had become.

6 and 7 show the refrigerator described in Japanese Patent Application Laid-Open No. 64-6686, FIG. 6 is a cross-sectional view of the main part showing a drawer device for a storage case of a conventional refrigerator, and FIG. In Figure 0, which is a perspective view of the main parts of a storage case of a conventional refrigerator showing a pulled-out state, 1 is an outer box of the refrigerator, 2 is a drawer-type door of the refrigerator that can be opened and closed, 3 is a side wall of an inner box inside the refrigerator, and 3a is a Recesses 4 formed on the inner box side wall 3 at opposite positions on the left and right along the depth direction are fixed rails with a U-shaped cross section fixed from the opening of the recess 3a to the back, and 5 are the fixed rails on the left and right near the opening of the refrigerator. This is a fixed roller rotatably fixed to the inner box side wall 3. 6 is fixed to the inner plate portion 2a of the door 2.

This is a rail member made of a steel plate that is slidably supported on the fixed roller 5, and has a sliding surface 6a of the fixed roller 5 and extends in the depth direction inside the refrigerator. A movable roller 7 is rotatably fixed to the inner part of the rail member 6 and rolls within the fixed rail 4. Reference numeral 8 denotes a storage case located in a chilled room, a vegetable room, etc., and is placed on the rail member 6 by a flange portion 8a around the upper opening. Reference numeral 9 denotes a heat sanitary material such as polyurethane injected between the refrigerator outer box 1 and the inner box side wall 3. Here, the operation of pulling out the storage case 8 will be explained. By pulling out door 2,
The rail member 6 fixed to N42 moves on the fixed roller 5 fixed to the inner box side wall 3, and 1ff is placed on the rail member 6.
The storage case 8 can be pulled out. At this time,
A movable roller 7 fixed to the inner part of the rail member 6 rolls on the inner surface of the fixed rail 4. Therefore, the storage case 8 of this type of refrigerator can be pulled out smoothly.

[Problems to be Solved by the Invention] However, conventional refrigerators employ a rail structure in which the storage case 8 is placed on the rail member 6 made of m-plate as a pull-out device for the storage case inside the refrigerator. In this rail structure, a rail member 6 is inserted between the storage case 8 and both inner compartment side walls 3.

Therefore, a space is required to insert the rail member 6 between the inner box side wall 3 and the storage case 8, and the width of the storage case 8 has to be reduced by that amount.

Therefore, in this type of refrigerator, there is a problem in that it is necessary to ensure a smooth draw-out operation of the storage case 8, and also to eliminate unnecessary space inside the refrigerator due to the rail structure and to make effective use of the inside of the refrigerator. Ta.

The purpose of the present invention is to eliminate unnecessary space inside the refrigerator.

To provide a refrigerator having a structure that increases the width of a storage case.

Means for Solving Problem C11] In order to achieve the above object, the refrigerator of the present invention includes a fixed rail arranged from the opening to the back of the refrigerator, a fixed roller fixed near the opening of the refrigerator, and 1. A storage case having an L-shaped rail portion formed in the front-rear direction and having a sliding surface for the fixed roller on the lower surface thereof integrally formed at a left-right relative position of a flange portion of the upper opening, and a storage case capable of rolling along the fixed rail. a movable roller fixed to a protruding portion at the back of the side wall of the storage case; and a movable roller formed at the rear of the cross-shaped rail portion;
The storage case includes a stop part that stops on the fixed roller when the storage case is pulled out, and a support part that is formed on the front wall of the storage case and is fixed to or removably engaged with the inner plate part of the door.

[Function] As configured above, the present invention serves as a pull-out device for a storage case in a refrigerator. A letter-shaped rail part is integrally formed, and the storage case can be fixed to the door by the drawer and insertion operations of A, or a removable support part is formed on the front wall of the storage case, and an M-shaped rail part is formed on the front wall of the storage case. A fixed roller rotatably fixed to the opening of the refrigerated chamber makes it movable, and a movable roller that can roll along a fixed rail is rotatably fixed to a protrusion at the back of the side wall of the storage case. Because of this, the operation of pulling out the storage case can be made extremely smooth.

Furthermore, the rail structure is positioned relative to the left and right sides of the flange portion of the storage case, and no steel plate rail member is interposed between the storage case and the side wall of the inner box, so the width of the storage case can be expanded.

[Example 1] An example of the present invention will be described below with reference to FIGS. 1 to 3. In addition, the conventional example and specific parts will be described. FIG. 1 is a cross-sectional view of the main parts of a refrigerator storage case drawer device according to an embodiment of the present invention, and FIG.
A vertical cross-sectional view showing a drawer device for a storage case of a Wi refrigerator,

The storage case E0 can also be moved on the fixed rollers 5 and the storage case E0 can be pulled out. This fixed roller 5 rotates according to the movement of the sliding surface 10b. Then, a stop portion 10d is attached to the fixed roller 5.
The storage case 10 can be pulled out until it comes into contact with the storage case 10.

Also, at this time, the protrusion 1 at the back of the side wall of the storage case 10
The movable roller 7 fixed at 0j rolls on the inner surface of the fixed rail 4.

Therefore, the refrigerator of this embodiment is the same as the conventional one.

The operation of pulling out the storage case 10 can be performed extremely smoothly.

In particular, in this embodiment, the rail structure of the storage case drawer device is located on the right and left sides of the flange portion 10a of the storage case 10, so the rail member made of a drawing board is provided between the inner wall 3 and the storage case 10. becomes unnecessary. Therefore, the width of the storage case 10 can be increased, and the internal volume can be effectively utilized.

Next, another embodiment of the present invention will be described.
