FIG. 3 is a perspective view seen from the front of an embodiment, and FIG. 4 is a perspective view from a rear view of FIG. 3. This will be described below with reference to Figs. 3 and 4. Fig.

A refrigerator according to an embodiment of the present invention includes an inner door 70 rotatably installed inside a door of a refrigerator compartment 20 or a freezer compartment 30, a main basket 72 fixed to the inner door 70, And an auxiliary basket (80). In FIGS. 3 and 4, only the side frames of the inner door 70 are shown cut away for convenience of explanation. One side of the inner door 70 is disposed adjacent to the rotating door of the refrigerating chamber door 20 or the hinge of the freezing chamber door 30 so as to be located at the same point as the refrigerating chamber door 20 or the freezing chamber door 30, As shown in Fig.

2 shows a structure in which the inner door 20 is installed inside the refrigerator compartment door 20 but the refrigerator compartment door 20 is provided inside the refrigerator compartment door 30, So that the inner door 70 is installed in the freezer compartment door 30 is not described separately.

For convenience of explanation, the freezer compartment door 30 and the refrigerator compartment door 20 will be collectively described by an external door at a time.

The main basket 72 is fixedly installed on the inner door 70 so that the height of the main basket 72 can not be changed while the auxiliary basket 80 is vertically movably coupled to the inner door 70. Particularly, the auxiliary basket 80 is installed above the main basket 72.

The refrigerator includes a first fixing portion 90 for fixing the auxiliary basket 80 to the inner door 70 and a second fixing portion 76 for fixing the main basket 72 to the inner door 70, . Particularly, the first fixing part 90 is configured to move the auxiliary basket 80 up and down the inner door 70, while the second fixing part 76 is configured to move the main basket 72, To the predetermined position of the inner door (70).

Since the first fixing part 90 connects both sides of the auxiliary basket 80 to the inner door 70, two pieces are provided symmetrically on both sides of the auxiliary basket 80.

In particular, the first fixing part 90 is preferably disposed in front of the storage space in which the food is received in the auxiliary basket 80. In this case, the storage space means the inner space of the auxiliary basket 80 having a rectangular parallelepiped shape having an open upper surface, and food can be drawn in or drawn out through the opened upper surface.

The reason why the first fixing portion 90 is disposed in front of the storage space is that when the user opens the outer door and the inner door 70 is not opened, So that the auxiliary basket 80 can be easily moved up and down.

In other words, if the user opens only the outer door and does not open the inner door 70, the user may place the first fixing portion 90 in front of the user, and the user may place the first fixing portion 90 in front of the rear portion (in the direction in which the user looks at the freezing chamber or the refrigerating chamber) A storage space for the auxiliary basket (80) is disposed.

On the other hand, the second fixing part 76 is provided with a receiving space 77 in which a part of the first fixing part 90 can be received. The accommodating space 77 can have a substantially rectangular parallelepiped shape. The shape of the receiving space 77 is specifically shown in Fig.

The second fixing part 76 includes a first fixing part 78 and a second fixing part 79 that connect the inner door 70 and the main basket 72, respectively. The first fixing piece 78 and the second fixing piece 79 are shaped like a plate connecting the main basket 72 and the inner door 70 individually. Therefore, the receiving space 77 may be formed between the first fixing piece 78 and the second fixing piece 79 so as to be spaced from each other.

The height of the first fixing piece 78 and the second fixing piece 79 may be different from each other. The height of the first fixing piece 78 is higher than the height of the second fixing piece 79 because the first fixing piece 78 is installed outside the second fixing piece 79, It is possible. This is because when the auxiliary basket 80 is moved to the upper surface of the main basket 72 by the protruding components, the first fixing part 90 is provided with various components protruding inward, So that the restriction can be reduced. In other words, it is preferable that the height of the second fixing piece 79 is lower than the height of the first fixing piece 78 because of the restriction of the component protruding inward of the first fixing part 90.

Since the second fixing portion 76 also connects both sides of the main basket 72 in the same manner as the first fixing portion 90, two of the main fixing portions 76 are provided symmetrically on both sides of the main basket 72 .

The auxiliary basket 80 may be provided on the main basket 72 and may be lowered to the same height as the main basket 72. The auxiliary basket 80 is connected to the inner door 70 by the first fixing part 90 and the main basket 72 is fixed to the inner door 70 by the second fixing part 76. [ So that the auxiliary basket 80 can not move to the lower portion of the main basket 72.

The height at which the auxiliary basket 80 can be lowered most is a position where the main basket 72 is installed. The main basket 72 and the auxiliary basket 80 are brought into contact with each other while the lower surfaces of the main basket 72 and the auxiliary basket 80 contact with each other when the auxiliary basket 80 is lowered to the maximum extent .

The main basket 72, which is the storage space of the inner door 70, was inspected by applicants to store various foods such as water or beverages as well as various health foods or side dishes. Therefore, when storing food such as beverage bottles having a large height while moving the auxiliary basket 80 up and down, the main basket 72 and the auxiliary basket 80 can be stacked. On the other hand, in order to store foods such as side dishes having a low height, the food can be stored by moving the auxiliary basket 80 to the upper portion of the main basket 72 and then installing two food surfaces.

The lower surfaces of the auxiliary basket (80) and the main basket (72) are both closed. 7, when the auxiliary basket 80 and the main basket 72 are overlapped with each other, they are formed by the storage space formed by the auxiliary basket 80 and the main basket 72 The storage spaces become coincident with each other, and the food can be substantially put into the auxiliary basket 80 only.

At this time, as shown in FIG. 7, if the auxiliary basket 80 and the main basket 72 are overlapped, one storage space may be formed.

On the other hand, when the auxiliary basket 80 and the main basket 72 are separated from each other, food may be stored in the auxiliary basket 80 and the main basket 72, respectively. This is because the auxiliary basket 80 and the main basket 72 form a storage space in which foods can be individually stored.

Figs. 5 and 6 are views showing a state in which the cover is opened in the main part of Fig. 3. Fig. Specifically, in FIGS. 5 and 6, the first engaging portion is shown in detail, and it is common in that the cover is opened. However, in FIG. 5, the hook is coupled to the groove of the first guide member, whereas the hook is rotated clockwise and is not coupled to the groove of the first guide member. This will be described below with reference to Figs. 5 and 6. Fig.

The first fixing part 90 includes a first guide member 92 and a second guide member 94 installed on the inner door 70. The moving member 93 is provided between the first guide member 92 and the second guide member 94 so that the moving member 93 can move between the first guide member 92 and the second guide member 94. [ Unlike the second guide member 94, the auxiliary basket 80 is installed.

The first guide member 92 and the second guide member 94 are elongated along the vertical plane of the inner door 70. The auxiliary basket 80 is movable to a range where the first guide member 92 and the second guide member 94 extend.

The moving member 93 includes a supporting piece 93b supported on both sides by the first guide member 92 and the second guide member 94. The support piece 93b is disposed in the space between the first guide member 92 and the second guide member 94 so that the first and second guide members 92, Up or down along the direction. The support piece 93b may be in the shape of a rectangle shaped bar so as to be supported on both sides while being in surface contact with the first guide member 92 and the guide member 94. [

A first bent piece 93a extending toward the second guide member 94 at one end of the support piece 93b and a second bent piece 93b extending toward the first guide member 92 at the other end of the support piece 93b. And a second bent piece 93c. The first bending piece 93a and the second bending piece 93c extend in mutually opposite directions at different positions of the supporting piece 93b. The first bending piece 93a, the supporting piece 93b and the second bending piece 93c may have a shape of '┏ ┛' as a whole. The first bending piece 93a and the second bending piece 93c extend differently from each other around the support piece 93b so that the support piece 93b is positioned between the first guide member 92 and the second guide piece 92b, The second guide member 94 can be maintained in a stable state of engagement.

Meanwhile, the first guide member 92 may be a rack having a plurality of grooves. The first guide member 92 is formed in a line so that the plurality of grooves have a gap therebetween, and is elongated along the vertical direction of the inner door 70.

On the other hand, an extension piece 95 may be provided at a portion connected to the auxiliary basket 80 from the second bending piece 93c. The extension piece 95 is provided between the second bent piece 93c and the auxiliary basket 80 so that the auxiliary basket 80 is spaced apart from the extended piece 95 by a predetermined distance .

The extension piece 95 is provided with a depression 95a to be recessed to a predetermined depth and a cover 99 is provided to finish the depression 95a so as not to be exposed to the user. It is preferable that the depression 95a is formed at a portion contacting the first guide member 92 or a portion adjacent to the second bending piece 93c.

The depression 95a is provided with a hook 97 fixed to one of the plurality of grooves. The hooks 97 are axially laterally axially centered and can be rotated about an axis.

An elastic member 96 is provided at one end of the hook 97 to elastically support the hook 97 axially coupled thereto. 6, when the user turns the hook 97 clockwise in the state shown in Fig. 5, since the elastic member 96 has a restoring force against the compressive force, the elastic member 96 As being compressed, the hook 97 is rotated clockwise. At this time, if the force applied by the user is removed, the hook 97 can be rotated counterclockwise by the restoring force of the elastic member 96 as shown in FIG.

5, when the elastic member 96 is sufficiently tensioned, since the hook 97 is inserted into one of the grooves of the first guide member 92, the position of the auxiliary basket 80 is fixed . On the other hand, in order for the user to change the position of the auxiliary basket 80, the hook 97 is rotated clockwise to remove the hook 97 from the groove and adjust the auxiliary basket 80 to a desired height do.

5, the elastic member 96 may be deformed into a member capable of generating a restoring force against a compressive force by a leaf spring, a coil spring, or the like.

A seating jaw for limiting the rotation path of the hook 97 is formed on the opposite side of the position where the elastic member 96 is provided with the hook 97 therebetween. The mounting jaw has a surface that is in surface contact with the hook 97. When the hook 97 contacts the seating jaw, the rotation of the hook 97 in the counterclockwise direction is restricted, and the hook 97 stops. That is, due to the restoring force of the elastic member 96, the hook 97 must continue to rotate in the counterclockwise direction, but the hook 97 is not rotated in a counterclockwise direction by more than a predetermined angle.

The first fixing part 90 may further include an operating piece 98 that rotates the hook 97 around an axis. The operating piece 98 extends from the hook 97 so that the user can grasp the finger on the operating piece 98 to rotate the hook 97. [

The operation piece 98 is preferably exposed to the outside so that the user can access the cover 99 even when the cover 99 is installed. This is because it is possible for the user to enhance the convenience of the user by allowing the cover 99 to operate the operating piece 98 while sealing the depression 95a.

The cover 99 may close the depression 95a so that the hook 97 and the elastic member 96 are not exposed to the outside.

FIG. 8 is a perspective view of a basket basket according to another embodiment of the present invention, and FIG. 9 is a view illustrating a state in which the basket basket of FIG. 8 is overlapped with the basket basket. This will be described below with reference to Figs. 8 and 9. Fig.

8 and 9, there is a difference in that the lower surface of the auxiliary basket 80 is opened unlike the embodiment of Figs. 3 to 7 described above. In other embodiments, other portions except the shape of the auxiliary basket 80 are the same as those of the embodiment. In particular, the lower surface of the main basket 72 is hermetically sealed in the same manner as in the embodiment.

When the lower surface of the auxiliary basket 80 is opened, the height of the auxiliary basket 80 can be adjusted to stably store the food stored in the main basket 72. When the food stored in the main basket 72 is a bottle having a large height such as a beverage bottle, when the food is stored only in the main basket 72, when the inner door 70 is rotated, the food is shaken and the main basket 72 And the like. In this case, when the auxiliary basket 80 is lifted from the main basket 72, the middle part of the beverage bottle can be supported by the auxiliary basket 80, It is possible to prevent falling.

On the other hand, in order to take out the beverage bottle housed in the main basket 72, the beverage bottle can be taken out after the auxiliary basket 80 is lowered. When the auxiliary basket 80 is lowered, the space for exposing the beverage bottle to the outside is increased, so that the user's hand can easily access the beverage bottle. The structure for raising or lowering the auxiliary basket 80 described above is the same as that described in the embodiment.

In other words, unlike the example described with reference to FIGS. 3 to 7, when the auxiliary basket 80 is received in the main basket 72 and overlapped with each other, the same shape as shown in FIG. 9 can be obtained. In this case, unlike the above-described example, the lower surface of the auxiliary basket 80 is opened, so that the stored food is seated on the lower surface of the main basket 72.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
