Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a refrigerator with a pull-out door.

(b) Prior Art Conventionally, this type of refrigerator with a pull-out door supports the first container with a frame on the rear side so that it can be pulled out in conjunction with the door. Further, in order to organize the food inside the first container, a second container smaller than the first container is provided, and this second container is movable within the first container.

However, in the past, this was made so that it could be moved from side to side, so if there was tall food on the side of the second container, it would be impossible to move it. As shown, the second container could be moved back and forth.

(c) Problems to be Solved by the Invention In the above-mentioned publication, since the second container can be moved back and forth relative to the first container, the movement is not hindered by the presence of other foods. If the second container is moved rearward with the container pulled out, there is a problem that the second container may fall into the refrigerator because the rear part of the second container cannot be supported.

The present invention aims to solve such problems.

(d) Means for Solving the Problems The present invention provides a first container that is pulled out in conjunction with a pull-out door that is attached to the front of the refrigerator so as to be openable and closable, a second container that is disposed inside the first container, and a second container that is placed inside the first container. In a refrigerator equipped with a partition front member installed on the left and right sides of the refrigerator opening edge above the container, a guide rail formed in the front-rear direction on the first container, a first support rail formed in the front-rear direction on the city side wall, and a refrigerator are provided. A second support rail installed on the inner back wall or the partition front member, a front support part formed on the front part of the second container and movably supported by the guide rail, and a front support part formed on the rear part of the second container and movable on both support rails. freely(
A rear support portion capable of fully supporting the second container is provided, so that the second container can be freely moved in the front-rear direction relative to the first container.

(E) Effect According to the present invention, even if the second container is moved rearward with the first container pulled out, the second container will fall off because the rear part is supported by the first support rail and the second support rail. There's nothing to do.

(f) Embodiments Next, embodiments will be explained with reference to the drawings. Figure 1 shows the refrigerator (

The duct (24) extends further rearward and laterally from the Suita mouth (22), and is provided with an auxiliary blower (28) at its terminal end, and an auxiliary air outlet (29) in the partition plate (16) in front of the duct (24).
can be formed. Between the auxiliary blower (28) and the partition plate (16) is a duct (30) that communicates with the ice-making outlet (23).
) is formed. The auxiliary blower (28) is a propeller fan, which rotates and forcibly sucks the cold air discharged from the main blower (19) into the first freezing air from the auxiliary blower outlet (29) and the ice-making outlet (23). A large amount of cold air is blown into the chamber (14) to powerfully cool the inside of the first freezing chamber (14).

The inside of the first freezer compartment (14) is divided into upper and lower parts by a partition plate (32) installed corresponding to the ice-making outlet (23) (removed in Fig. 2), and the area below the partition plate (32) is partitioned into an upper and lower part. dish(
The partition plate (3

At the top, a first support rail (90) is attached in the front-rear direction with a distance maintained by the protrusion (9A) of the inner box (9). Further, on the upper left side of the partition part (83) of the container (56) is the partition plate (53) below, and the rear mounting part (92A> and the front mounting part (92B>) are connected to the back wall of the inner box (9) and the front of the partition. Element(
A second support rail (92) is installed between the two support rails (54) and extends in the front-rear direction. (93) is the guide rail (89).

(89) A locking part formed in the front part, which is a small container (58)
The rollers (R4) and (R4) are connected to both support rails (90
) and (92), respectively, so as to be slidable back and forth as indicated by the arrows in FIG. 9, and the rollers (R3) and (R3) are slidably supported by the guide rails (89) and (89), respectively. No. 315! ! When the door (6) is closed as shown in I, the roller (Rg) and (R,) are the locking parts (93).
Located in the front, the small container (58) is on the side! ! 2 (58A) and the partition (83) are located above the notches (84) and (85), and the inside thereof is used as a second vegetable compartment (94).

In this state, inside the containers (56) and (58), the partition plate (5
3) It is indirectly cooled by cold air falling from the surrounding area.

In addition, each vegetable compartment (sa), (94), and (87) can store vegetables classified by type.

Next, when the door (6) is pulled out from the state shown in Figure 3, the container (56)
) are pulled out together, and further rollers (Rs) and (Rg
) is locked by the locking part (93), and the small container (58) is also pulled out at the same time. In this state, the second and second vegetable compartments (8
6), (94) is opened upwards and can be used to dispense food.When dispensing food from the third vegetable compartment (87), the small container (58) is further removed from this state. Insulated box (1
1) When pushed inward, the rollers (Rs) and (R8) get over the locking part (93), so the small container (58) is pushed into the notch (
84) and is pushed into the rear insulation box (11). At this time, the rollers (R4) and (R,) are supported by sliding backwards on both support rails (90) and (92), so that the rear of the small container (58) is connected to the insulating box (11).
It will not fall off inside.

In addition, the front part of the small container (58) also has rollers (Rs), (R,

The second support rail (92) is connected to the inner box (9), the partition front member <5
4), it is possible to firmly absorb almost the entire load of the small container (58) when only the small container (58) is pushed in. For example, the upper partition plate (5)
3), the partition plate (5) is supported depending on the load.
3) may be deformed downward, but the present invention eliminates such a problem.

In this state, the third vegetable compartment (87) is opened upward, and the food inside can be ejected. Also, if the door (6) is closed, the rollers (R4) and (R4) will move to the support rail (9).
0), (92>The small container (58) is stationary as it comes into contact with the rear end, and only the container (56) moves rearward and is eventually stored in the state shown in FIG. 3.

(G) Effects of the Invention According to the present invention, the inside of the first container can be divided into the inside of the second container and other parts, so food can be stored in an organized manner, and the food under the second container can also be stored in the second container. It can be easily taken out by moving the second container backwards, and this movement is not obstructed.In particular, even if the second container is moved backwards, the front part is connected to the guide rail of the first container by the front support part. Nimata,
Since the rear part is supported by both support rails at the rear support part, it will not fall off and food can be stored stably.

In particular, since the support rail is installed between the inside of the refrigerator (ffl wall, the back wall, and the partition front member), the load of the second container can be effectively stopped and the other members will not be deformed.
