As shown in FIG. 9, when the second ice making tray 1410 creates ice using water supplied from the water supply unit 80, the fixed tray 1411 and the moving tray 1412 are positioned to be coupled to each other. It can be. At the position where the fixed tray 1411 and the moving tray 1412 are combined, a part of the second ice making cell inside the fixed tray 1411 and another part of the second ice making cell inside the moving tray 1412 are combined to form an integrated A second ice-making cell may be formed, and a second type of ice may be generated inside the second ice-making cell.

After the creation of the second type of ice is completed, as shown in FIGS. 10 and 11, the control unit controls the driving of the second driving unit 1420 so that the moving tray 1412 moves toward the second ejector 1440.

The configuration of the second ice making unit 1400 described above with reference to FIGS. 8 to 11 is only an example of an ice making unit provided in an ice making device of a refrigerator according to the spirit of the present disclosure, and the spirit of the present disclosure is thereto. Not limited.

In addition, with reference to FIGS. 1 to 11 , as an example of an ice making device for a refrigerator according to the spirit of the present disclosure, cold air generated in the storage compartment 20 is guided to the ice making device 1000 to perform first and second ice making. The structure of the intercooled ice making device that cools the water supplied to the trays 1310 and 1410 was explained as an example. However, the idea of the present disclosure is not limited thereto, and as an example, the idea of the present disclosure is to provide cold air directly by disposing separate refrigerant pipes in the first and second ice making trays 1310 and 1410 to cool the first and second ice making trays 1310. , 1410) can also be applied to the configuration of a direct-cooled ice making device that cools the water supplied to the ice maker.

Figure 12 is an enlarged view of a partial configuration of an ice making device for a refrigerator according to an embodiment of the present disclosure. Figure 13 is a cross-sectional view of the ice making device of a refrigerator according to an embodiment of the present disclosure. Figure 14 is an enlarged view of A in Figure 13. Figure 15 is a cross-sectional view showing an ice making device mounted on the inside of a refrigerator according to an embodiment of the present disclosure. Figure 16 is an enlarged cross-sectional view showing B of Figure 15 enlarged. Figure 17 is an enlarged cross-sectional view showing the state when the inner wall of the inner case in Figure 16 is deformed.

Referring to FIGS. 12 to 17 , the ice maker case 1200 of the ice maker 1000 may include elastic protrusions 1220a and 1220b provided on the ice maker case walls 1210a and 1210b.

As described above, the ice maker case 1200 includes a first ice maker case wall 1210a supported on the first inner wall 11a of the inner case 11, and a first ice maker case wall 1210a supported on the second inner wall 11b of the inner case 11. 2 It may include an ice maker case wall (1210b). The first ice maker case wall 1210a and the second ice maker case wall 1210b may form the outer walls of the ice maker case 1200 in the left and right directions of the ice maker 1000, respectively.

When the ice maker 1000 is mounted on the inner case 11 as shown in FIGS. 15 to 17, etc., an error may occur in the specifications of the ice maker case 1200 and the internal case 11. Causes of these errors may include limitations in the design and manufacturing of the inner case 11 and limitations in the design and manufacturing of the ice maker case 1200. Alternatively, as shown in FIG. 17, after foaming the body insulation 13 between the inner case 11 and the outer case 12, the shape of the foamed body insulation 13 may be deformed. Alternatively, even after the ice maker 1000 is mounted on the inner case 11, deformation may occur in the inner walls 11a and 11b of the inner case 11 or the ice maker case 1200 of the ice maker 1000.

In this way, when an error occurs in the specifications of the ice maker case 1200 and the specifications of the inner case 11, the relative position between the first inner wall 11a and the first ice maker case wall 1210a, the second inner wall 11b and Errors may occur in the relative position between the second ice maker case walls 1210b and the conventional design. Accordingly, problems may occur in the ice maker 1000 being supported on the inner walls 11a and 11b of the inner case 11.

In addition, the relative position between the first inner wall 11a and the first ice maker case wall 1210a, the relative position between the second inner wall 11b and the second ice maker case wall 1210b, etc. are different from those in the conventional design. Due to the problem, when a user looks at the ice maker 1000 mounted on the inner case 11, the apparent quality of the ice maker 1000 may deteriorate. For example, as the relative position between the inner walls 11a and 11b and the ice maker case walls 1210a and 1210b is different from the conventional design, the front part 1230 of the ice maker case 1200 is positioned horizontally of the refrigerator 1. It may be positioned to be inclined with respect to the direction. Since the front portion 1230 forms the front exterior of the ice maker 1000, the external appearance quality of the ice maker 1000 may deteriorate.

In addition, when the ice maker 1000 is mounted on the inner case 11, the ice maker case 1200 and the inner case are in contact with the inner walls 11a and 11b of the ice maker case 1200. Scratches may occur between the inner walls 11a and 11b of the ice maker 11, causing damage to the ice maker 1000 or the inner case 11. This may become a further problem if an error occurs in the specifications of the ice maker case 1200 and the internal box 11. This may be a problem during the process of mounting the ice maker 1000 to the inner case 11, or even after the ice maker 1000 is mounted on the inner case 11, the ice maker case 1200, the inner case 11, and the main body insulation This may be a problem due to variations in (13).

To solve this problem, the ice maker case 1200 may include elastic protrusions 1220a and 1220b that interfere with the inner walls 11a and 11b of the inner case 11 and are elastically deformable.

Specifically, the ice maker case 1200 may include a first elastic protrusion 1220a provided on the first ice maker case wall 1210a. The first elastic protrusion 1220a may interfere with the first inner wall 11a. The first elastic protrusion 1220a may be provided to be elastically deformable in the direction pressed by the first inner wall 11a.

The first elastic protrusion 1220a may be provided on the right side of the ice maker case 1200 when viewed from the front. The first elastic protrusion 1220a may have a shape that protrudes to the right side of the ice maker case 1200 when viewed from the front.

The first elastic protrusion 1220a may be provided to be pressed in a direction from the first inner wall 11a of the inner case 11 toward the ice maker case 1200. The first elastic protrusion 1220a may be provided to be pressed in a direction from the first inner wall 11a of the inner case 11 toward the first ice maker case wall 1210a. In other words, the first elastic protrusion 1220a may be provided to be pressed in a direction from the first inner wall 11a of the inner case 11 toward the second inner wall 11b. As shown in FIGS. 12 to 17 , the first elastic protrusion 1220a may be pressed toward the inside of the storage compartment 20 in the left and right directions by the first inner wall 11a.

As the first elastic protrusion 1220a is pressed, the first elastic protrusion 1220a may be provided to be elastically deformable. That is, the first elastic protrusion 1220a may be provided to be elastically deformable in the direction pressed by the first inner wall 11a.

As the first elastic protrusion 1220a is elastically deformable, the position of the first ice maker case wall 1210a with respect to the first inner wall 11a can also be adjusted. As the position of the first ice maker case wall 1210a with respect to the first inner wall 11a is adjustable, the position of the ice maker case 1200 with respect to the inner box 11 may be adjustable.

13 and 14 as an example, when the ice maker 1000 is not mounted on the inner case 11, the first elastic protrusion 1220a does not interfere with the first inner wall 11a, and the first elastic protrusion 1220a does not interfere with the first inner wall 11a. 1 It may be in a state where it is not pressed by the inner wall 11a and thus is not elastically deformed. In this case, based on FIGS. 13 and 14 , the right end of the first elastic protrusion 1220a may protrude to the right of the outer surface of the first ice maker case wall 1210a.

15 and 16 as an example, when the ice maker 1000 is mounted on the inner case 11, the first elastic protrusion 1220a interferes with the first inner wall 11a, and the first inner wall 11a It can be pressurized by (11a). At this time, the first elastic protrusion 1220a may be elastically deformed, and the right end of the first elastic protrusion 1220a may be moved to the left compared to the position in FIGS. 13 and 14. In other words, the first elastic protrusion 1220a is positioned so that the end facing the first inner wall 11a, that is, the end in contact with the first inner wall 11a, faces the inside of the storage compartment 20 in the left and right directions. It can be elastically deformed to move.

Taking what is shown in FIG. 17 as an example, the first inner wall 11a may be deformed due to causes such as deformation of the main body insulation material 13 while the ice maker 1000 is mounted on the inner case 11. For example, when deformation occurs in the main body insulating material 13 so that the volume of the main insulating material 13 increases, the first inner wall 11a may be deformed in a direction toward the inside of the storage compartment 20 in the left and right directions. . Accordingly, the degree to which the first elastic protrusion 1220a is pressed by the first inner wall 11a may increase, and the degree to which the first elastic protrusion 1220a is elastically deformed is the degree shown in FIGS. 15 and 16. It can increase by comparison.

Since the appearance of the ice maker 1000 revealed to the user is mainly the front appearance of the ice maker 1000, it is desirable to adjust the relative position between the first ice maker case wall 1210a and the first inner wall 11a at least from the front. You can. Accordingly, the first elastic protrusion 1220a may be disposed closer to the opening 10a of the inner case 11 than to the rear wall 11c of the inner case 11. More specifically, the first elastic protrusion 1220a may be disposed on the front portion of the first ice maker case wall 1210a and may be disposed adjacent to the front portion 1230 of the ice maker case 1200. However, the present invention is not limited to this, and the first elastic protrusion 1220a may be provided in various positions. As an example, the first elastic protrusion 1220a may be disposed adjacent to the rear wall 11c of the inner case 11. Or, as an example, the first elastic protrusion 1220a may be provided at a position separated from each of the opening 10a and the rear wall 11c of the inner case 11 by approximately the same distance.

When the ice maker 1000 is mounted on the inner case 11, the first elastic protrusion 1220a may be positioned so as not to directly interfere with the first holder 11aa. In other words, the first elastic protrusion 1220a may be positioned to interfere with a position on the first inner wall 11a where the first holder 11aa is not provided.

For example, as shown in FIGS. 15 to 17, the first elastic protrusion 1220a may be provided below the first holder 11aa. In detail, the first elastic protrusion (1220a) may be disposed downward in a direction perpendicular to the first holder (11aa), but is not limited thereto, and the first elastic protrusion (1220a) is disposed below the first holder (11aa). It may be arranged below in the vertical direction, in a direction moved in the front-to-back direction, that is, in the diagonal direction.

For example, unlike the first elastic protrusion 1220a shown in FIGS. 15 to 17 , the first elastic protrusion 1220a may be provided above the first holder 11aa.

However, the present invention is not limited thereto, and the first elastic protrusion 1220a may be positioned to interfere with the first holder 11aa.

The ice maker case 1200 may include a second elastic protrusion 1220b provided on the second ice maker case wall 1210b. The second elastic protrusion 1220b may interfere with the second inner wall 11b. The second elastic protrusion 1220b may be provided to be elastically deformable in the direction pressed by the second inner wall 11b.

The second elastic protrusion 1220b may be provided on the left side of the ice maker case 1200 when viewed from the front. The second elastic protrusion 1220b may have a shape that protrudes to the left of the ice maker case 1200 when viewed from the front.

The second elastic protrusion 1220b may be provided to be pressed in a direction from the second inner wall 11b of the inner case 11 toward the ice maker case 1200. The second elastic protrusion 1220b may be provided to be pressed in a direction from the second inner wall 11b of the inner case 11 toward the second ice maker case wall 1210b. In other words, the second elastic protrusion 1220b may be provided to be pressed in a direction from the second inner wall 11b of the inner case 11 toward the first inner wall 11a. As shown in FIGS. 12 to 17 , the second elastic protrusion 1220b may be pressed toward the inside of the storage compartment 20 in the left and right directions by the second inner wall 11b.

As the second elastic protrusion 1220b is pressed, the second elastic protrusion 1220b may be provided to be elastically deformable. That is, the second elastic protrusion 1220b may be provided to be elastically deformable in the direction pressed by the second inner wall 11b.

As the second elastic protrusion 1220b is elastically deformable, the position of the second ice maker case wall 1210b with respect to the second inner wall 11b can also be adjusted. As the position of the second ice maker case wall 1210b with respect to the second inner wall 11b is adjustable, the position of the ice maker case 1200 with respect to the inner box 11 may be adjustable.

13 as an example, when the ice maker 1000 is not mounted on the inner case 11, the second elastic protrusion 1220b does not interfere with the second inner wall 11b, and the second inner wall (11b) It may be in a state of no elastic deformation because it is not pressurized by 11b). In this case, with reference to FIG. 13 , the left end of the second elastic protrusion 1220b may protrude to the left of the outer surface of the second ice maker case wall 1210b.

15 as an example, when the ice maker 1000 is mounted on the inner case 11, the second elastic protrusion 1220b interferes with the second inner wall 11b, and the second inner wall 11b It can be pressurized by . At this time, the second elastic protrusion 1220b may be elastically deformed, and the left end of the second elastic protrusion 1220b may be moved to the right compared to the position in FIG. 13. In other words, the end of the second elastic protrusion 1220b in the direction facing the second inner wall 11b, that is, the end in contact with the second inner wall 11b, is positioned in a position inward in the left and right directions of the storage compartment 20. It can be elastically deformed to move.

As described with respect to the first elastic protrusion 1220a, taking the example shown in FIG. 17 as an example, the second elastic protrusion 1220a may be deformed due to the main body insulating material 13 being deformed while the ice making device 1000 is mounted on the inner case 11. The inner wall 11b may be deformed. For example, when deformation occurs in the main body insulating material 13 so that the volume of the main insulating material 13 increases, the second inner wall 11b may be deformed in a direction toward the inside of the storage compartment 20 in the left and right directions. . Accordingly, the degree to which the second elastic protrusion 1220b is pressed by the second inner wall 11b may increase, and the degree to which the second elastic protrusion 1220b is elastically deformed increases compared to the degree shown in FIG. 15. can do.

Since the appearance of the ice maker 1000 revealed to the user is mainly the front appearance of the ice maker 1000, it is desirable to adjust the relative positions between the second ice maker case wall 1210b and the second inner wall 11b at least from the front. You can. Accordingly, the second elastic protrusion 1220b may be disposed closer to the opening 10a of the inner case 11 than to the rear wall 11c of the inner case 11. More specifically, the second elastic protrusion 1220b may be disposed on the front part of the second ice maker case wall 1210b and adjacent to the front part 1230 of the ice maker case 1200. However, the present invention is not limited to this, and the second elastic protrusion 1220b may be provided in various positions. As an example, the second elastic protrusion 1220b may be disposed adjacent to the rear wall 11c of the inner case 11. Or, as an example, the second elastic protrusion 1220b may be provided at a position separated from each of the opening 10a and the rear wall 11c of the inner case 11 by an approximately equal distance.

When the ice maker 1000 is mounted on the inner case 11, the second elastic protrusion 1220b can be positioned so as not to directly interfere with the second holder 11bb. In other words, the second elastic protrusion 1220b may be positioned to interfere with a position on the second inner wall 11b where the second holder 11bb is not provided.

For example, as shown in FIG. 15, the second elastic protrusion 1220b may be provided below the second holder 11bb. In detail, the second elastic protrusion (1220b) may be disposed downward in a direction perpendicular to the second holder (11bb), but is not limited thereto, and the second elastic protrusion (1220b) is disposed below the second holder (11bb). It may be arranged below in the vertical direction, in a direction moved in the front-to-back direction, that is, in the diagonal direction.

For example, unlike the second elastic protrusion 1220b shown in FIG. 15 , the second elastic protrusion 1220b may be provided above the second holder 11bb.

However, the present invention is not limited thereto, and the second elastic protrusion 1220b may be positioned to interfere with the second holder 11bb.

In this way, the first elastic protrusion 1220a and the second elastic protrusion 1220b are provided to be elastically deformable so that the position of the ice maker case 1200 with respect to the first inner wall 11a and the second inner wall 11b is adjusted. You can.

With the above configuration, the ice maker 1000 can be stably supported on the inner walls 11a and 11b of the inner case 11, including the elastic protrusions 1220a and 1220b. In addition, the elastic protrusions (1220a, 1220b) are elastically deformable in the direction pressed by the inner walls (11a, 11b), preventing damage to the inner walls (11a, 11b) of the ice maker 1000 and the inner case (11). It can be prevented. Additionally, the relative position of the ice maker 1000 with respect to the inner case 11 can be adjusted by the elastic protrusions 1200a and 1220b, and the external quality of the product can be improved.

Meanwhile, in the above, the ice maker case 1200 is provided on the first ice maker case wall 1210a and includes a first elastic protrusion 1220a interfering with the first inner wall 11a of the inner case 11, and a second ice maker case wall ( Although the description has been made on the premise that the second elastic protrusion 1220b is provided at 1210b and interferes with the second inner wall 11b of the inner case 11, the spirit of the present disclosure is not limited thereto.

As an example, the ice maker case 1200 may include only the elastic protrusion 1220a provided on the first ice maker case wall 1210a and interfering with the first inner wall 11a of the inner case 11. The elastic protrusion 1220a may be provided so that the position between the first inner wall 11a and the first ice maker case wall 1210a can be adjusted. Therefore, even in this case, the elastic protrusion 1220a can be provided to adjust the relative position of the ice maker case 1200 with respect to the inner case 11, and the effect of the invention provided according to the spirit of the present disclosure can be provided. .

Alternatively, as an example, the ice maker case 1200 may include only the elastic protrusion 1220b provided on the second ice maker case wall 1210b and interfering with the second inner wall 11b of the inner case 11. The elastic protrusion 1220b may be provided so that the position between the second inner wall 11b and the second ice maker case wall 1210b can be adjusted. Therefore, even in this case, the elastic protrusion 1220b can be provided to adjust the relative position of the ice maker case 1200 with respect to the inner case 11, and the effect of the invention provided according to the spirit of the present disclosure can be provided. .

Meanwhile, the first ice maker case wall 1210a and the second ice maker case wall 1210b may have the same or at least corresponding configurations.

Therefore, the description of the second ice maker case wall 1210b may be omitted below, and the first ice maker case wall 1210a may be referred to as the ice maker case wall 1210a. The description of the configuration of the ice maker case wall 1210a may also be correspondingly applied to the configuration of the second ice maker case wall 1210b.

Additionally, the first elastic protrusion 1220a and the second elastic protrusion 1220b may have the same or at least corresponding configurations.

Therefore, the description of the second elastic protrusion 1220b may be omitted below, and the first elastic protrusion 1220a may be referred to as elastic protrusion 1220a. The description of the configuration of the elastic protrusion 1220a can also be correspondingly applied to the configuration of the second elastic protrusion 1220b.

Hereinafter, the configuration of the elastic protrusion 1220a of the ice maker case 1200 will be described in detail with reference to FIGS. 12 to 17.

The elastic protrusion 1220a may include an interference portion 1221a provided to interfere with the first inner wall 11a. The interference portion 1221a may protrude from the first ice maker case wall 1210a toward the first inner wall 11a in the first direction (X).

The interference portion 1221a may be provided to be movable in a direction parallel to the first direction (X) by elastic deformation. In detail, the interference portion 1221a and the first inner wall 11a may be in contact with each other in a direction parallel to the first direction (X), and the interference portion 1221a may be moved in the first direction by the first inner wall 11a. It can be pressed in a direction parallel to (X). The interference portion 1221a may be provided to be movable in a direction parallel to the first direction (X) as it is pressed by the first inner wall 11a.

For example, when the ice maker 1000 is mounted on the inner case 11 (from the state of FIGS. 13 and 14 to the state of FIGS. 15 and 16), the interference unit 1221a moves in the first direction (X). It can be moved toward the inside of the storage compartment 20. For example, when the first inner wall 11a is deformed while the ice maker 1000 is mounted on the inner case 11, the interference unit 1221a moves in the first direction (X) according to the deformation of the first inner wall 11a. It may be moved toward the inside of the storage compartment 20 (when changing from the state of FIGS. 15 and 16 to the state of FIG. 17), or the interference portion 1221a may be moved toward the inside of the storage compartment 20 in the first direction (X). ) may be moved toward the outside (when changing from the state of Figure 17 to the state of Figures 15 and 16). That is, the elastic protrusion 1220a is elastically deformed depending on the degree to which it is pressed by the first inner wall 11a. The degree to which the interference portion 1221a moves in a direction parallel to the first direction (X) may also vary depending on the degree of elastic deformation.

As an example, the first direction (X) may be a direction parallel to the left and right directions of the inner case 11.

The interference portion 1221a may extend in a second direction (Y) different from the first direction (X). The second direction Y may be parallel to the first inner wall 11a. In other words, the interference portion 1221a may extend in the second direction Y, which is parallel to the direction in which the first inner wall 11a extends.

As an example, the second direction (Y) may be perpendicular to the first direction (X). As an example, the second direction Y may be a direction parallel to the front-back direction of the inner case 11.

The interference portion 1221a has a shape that protrudes in the first direction (X) and extends in the second direction (Y) parallel to the first inner wall 11a, so that the interference portion 1221a protrudes from the first inner wall 11a. When interfered with, the pressure applied to the interference portion 1221a or the first inner wall 11a can be distributed. Furthermore, when the interference portion 1221a interferes with the first inner wall 11a, damage to the interference portion 1221a or the first inner wall 11a can be prevented.

The interference portion 1221a may include a contact surface 1221as1 and a corner surface 1221as2. The contact surface 1221as1 and the corner surface 1221as2 may be provided at one end of the interference portion 1221a in the first direction (X). The contact surface 1221as1 and the corner surface 1221as2 may be provided at one end of the interference portion 1221a facing the first inner wall 11a.

The contact surface 1221as1 may be provided at one end of the interference portion 1221a in the first direction (X) to contact the first inner wall 11a. The contact surface 1221as1 may be one surface of the interference portion 1221 and is in contact with the first inner wall 11a.

The position where the contact surface 1221as1 is provided in the interference portion 1221a may vary depending on the direction in which the interference portion 1221a contacts the first inner wall 11a. For example, the contact surface 1221as1 may be provided at one end of the interference portion 1221a in the left and right directions.

The corner surface 1221as2 may be bent and extended at an end of the contact surface 1221as1 in the second direction (Y). The corner surface 1221as2 may be formed to be inclined with respect to the second direction (Y). The corner surface 1221as2 may be bent at an end of the contact surface 1221as1 in the second direction (Y) and extend in a direction inclined with respect to the second direction (Y). The corner surface 1221as2 may extend in a direction away from the contact surface 1221as1 and the first inner wall 11a.

As shown in FIG. 12 and the like, the corner surface 1221as2 may be bent and extended at both ends of the contact surface 1221as1 in the second direction (Y). For example, the corner surface 1221as2 may be bent at the front and rear ends of the contact surface 1221as1, respectively, and may extend in the front-back direction and the inclined direction. However, the present invention is not limited thereto, and as an example, the corner surface 1221as2 may be bent and extended at one end of the contact surface 1221as1 in the second direction (Y). As an example, the corner surface 1221as2 may extend from the rear end of the contact surface 1221as1. The corner surface 1221as2 may extend obliquely from an end of the contact surface 1221as1 in the second direction in a direction toward the inside of the storage compartment 20 in the first direction (X).

For example, one end of the interference portion 1221a in the first direction (X) may be provided to have a curved shape. The contact surface 1221as1 and the corner surface 1221as2 may be connected to each other to form an overall curved shape (see the upper elastic protrusion 1220aa in FIG. 12).

As an example, the contact surface 1221as1 may extend in the second direction (Y), and the corner surface 1221as2 may extend at an angle different from the extension direction of the contact surface 1221as1 (lower elastic protrusion 1220ab in FIG. 12 ) reference.). The contact surface 1221as1 may extend long along the second direction (Y). The radius of curvature of the contact surface 1221as1 and the radius of curvature of the corner surface 1221as2 may be set to be different from each other. More specifically, the radius of curvature of the contact surface 1221as1 may be set to be larger than the radius of curvature of the corner surface 1221as2. It can be.

However, the present invention is not limited thereto, and the contact surface 1221as1 and the corner surface 1221as2 may be formed to have various shapes.

According to the above configuration, the corner surface 1221as2 may be provided so as not to directly contact the first inner wall 11a. In particular, when the ice maker 1000 is inserted and mounted in the inner case 11 in the second direction (Y), the contact surface 1221as1 may be in contact with the first inner wall 11a and interfere with it, but the corner surface 1221as2 may be in contact with the first inner wall 11a. It may not be in contact with the first inner wall 11a. That is, when the ice maker 1000 is mounted on the inner case 11 by sliding in the second direction (Y), the corner portion of the interference portion 1221a is adjacent to the first inner wall 11a due to the shape of the corner surface 1221as2. It is possible to prevent the first inner wall 11a or the elastic protrusions 1220a from being damaged due to scratching each other.

However, the spirit of the present disclosure is not limited thereto, and the interference portion of the elastic protrusion according to an embodiment of the present disclosure may be formed to have various shapes such that it interferes with the inner wall of the inner case.

12 to 17, the second direction Y in which the interference portion 1221a extends is shown to be parallel to the front-back direction of the inner case 11. However, as an example, the second direction in which the interference portion 1221a extends is shown in FIGS. It may be parallel to the vertical direction of the inner case 11. Furthermore, the corner surface 1221as2 may be bent and extended at an end of the contact surface 1221as1 in the vertical direction. In this case, when the ice maker 1000 is mounted on the inner case 11, if the ice maker 1000 is inserted into the inner case 11 in the vertical direction, the elasticity is formed by scratching between the elastic protrusion 1220a and the first inner wall 11a. It is possible to prevent the protrusion 1220a or the first inner wall 11a from being damaged.

The elastic protrusion 1220a may include a connection portion 1222a connected to the ice maker case wall 1210a. The connection portion 1222a may connect the ice maker case wall 1210a and the interference portion 1221a.

The connection portion 1222a may include a fixed end 1222ae1 fixed to the ice maker case wall 1210a. The connection portion 1222a may be provided to be elastically deformable with respect to the fixed end 1222ae1. The connection portion 1222a may be provided to be elastically deformable around the fixed end 1222ae1.

The connection portion 1222a may include a free end 1222ae2 opposite to the fixed end 1222ae1. The free end 1222ae2 may not maintain a fixed position relative to the ice maker case wall 1210a. The free end 1222ae2 may be one end of the connection portion 1222a connected to the interference portion 1221a. The above-described interference portion 1221a may extend from the free end 1222ae2 in the first direction (X). The interference portion 1221a may extend from the free end 1222ae2 toward the first inner wall 11a.

The connection portion 1222a may extend between the fixed end 1222ae1 and the free end 1222ae2. The connection portion 1222a may be provided to extend in a direction different from the direction in which the elastic protrusion 1220a is joined by the first inner wall 11a. More specifically, the interference portion 1221a may be provided to be pressed in the first direction (X) by the first inner wall 11a, and the connecting portion 1222a may be pressed in the first direction (X) from the fixed end 1222ae1. It may be arranged to extend in a different direction.

For example, the connection portion 1222a may extend from the fixed end 1222ae1 toward the free end 1222ae2 in a third direction (Z) perpendicular to the first direction (X) and the second direction (Y). As an example, the third direction Z may be parallel to the vertical direction of the inner case 11. That is, the fixed end 1222ae1 may be formed above the free end 1222ae2, and the upper end of the connecting part 1222a may be fixed to the ice maker case wall 1210a, and the lower end may be fixed to the interference part 1221a. It may be provided to be movable according to elastic deformation.

However, the present invention is not limited thereto, and the connection portion 1222a may extend in various directions from the fixed end 1222ae1 to the free end 1222ae2.

The connection portion 1222a may be made of an elastic material. The connection portion 1222a includes an elastic material, and when an external force is applied to the free end 1222ae2 while the fixed end 1222ae1 is fixed to the ice maker case wall 1210a, the connection portion 1222a moves the fixed end 1222ae1. It may be arranged to be elastically deformed around the center. As an example, the connection portion 1222a may be made of a plastic material. However, it is not limited to this, and the connection portion 1222a may be made of various materials that enable elastic deformation.

As described above, the interference portion 1221a may have a shape that protrudes in the first direction (X) so as to interfere with the first inner wall 11a. At this time, the connection portion 1222a may extend from the fixed end 1222ae1 toward the free end 1222ae2, and the interference portion 1221a may be bent at the free end 1222ae2 of the connection portion 1222a in the first direction (X ) can be extended. For example, as shown in FIG. 12, the connecting portion 1222a may extend in the third direction (Z), and the interference portion 1221a may be bent at the free end 1222ae2 and extend in the first direction (X). You can.

The interference portion 1221a may be formed integrally with the connection portion 1222a. When the connection part 1222a is made of an elastic material, the interference part 1221a may be made of an elastic material like the connection part 1222a.

However, the present invention is not limited to this, and the elastic protrusion 1220a including the interference portion 1221a and the connecting portion 1222a may be formed in various ways.

The ice maker case wall 1210a may include a cutout portion 1211a. The cut portion 1211a may be formed by cutting along the direction in which the connection portion 1222a extends.

The connection portion 1222a may be provided in the cut portion 1211a. The connection portion 1222a may be provided to be disposed in the cut area of the cut portion 1211a. Specifically, the fixed end 1222ae1 of the connection portion 1222a may be fixed to the ice maker case wall 1210a at the boundary portion of the cut portion 1211a. The free end 1222ae2 may be provided to be movable rather than fixed in the inner portion of the cut area of the cut portion 1211a. According to this configuration, the connection portion 1222a can be provided to be elastically deformable.

The cutout portion 1211a may extend in a direction parallel to the connection portion 1222a. The cut portion 1211a may be cut in a direction parallel to the direction in which the free end 1222ae2 extends from the fixed end 1222ae1.

The cutout portion 1211a may extend along the third direction (Z). As an example, the cut portion 1211a may extend along the vertical direction of the inner case 11. However, the present invention is not limited to this, and the cutout portion 1211a may extend in various directions depending on the shape of the connection portion 1222a.

The elastic protrusion 1220a may be formed by a cut portion 1211a such that parts other than the fixed end 1222ae1 fixed to the ice maker case wall 1210a are spaced apart from the ice maker case wall 1210a. The elastic protrusion 1220a may be fixed to the ice maker case wall 1210a by the fixed end 1222ae1, and other parts of the elastic protrusion 1220a other than the fixed end 1222ae1 are not restricted by the ice maker case wall 1210a. Therefore, when receiving an external force, it can easily be elastically deformed around the fixed end (1222ae1).

As shown in FIGS. 12 to 17 , the interference portion 1221a may be provided so that its position relative to the incision portion 1211a is variable as it is pressed by the first inner wall 11a. The cut portion 1211a is a component of the ice maker case wall 1210a and can maintain a fixed position with respect to the ice maker case wall 1210a. Meanwhile, the interference portion 1221a may be connected to the free end 1222ae2 of the connection portion 1222a provided in the cut portion 1211a, and accordingly, the interference portion 1221a is positioned relative to the cut portion 1211a when receiving an external force. can be variable. The interference portion 1221a is configured to contact the first inner wall 11a, and as the position of the interference portion 1221a with respect to the cut portion 1211a changes, the ice maker case 1200 with respect to the first inner wall 11a Relative positions can be adjusted.

13 and 14, when the ice maker 1000 is not mounted on the inner case 11, the end of the contact surface 1221as1 of the interference part 1221a protrudes from the ice maker case wall 1210a, When the ice maker 1000 is mounted on the inner case 11, the difference in the position where the end of the contact surface 1221as1 side of the interference part 1221a protrudes from the ice maker case wall 1210a is the difference between the interference part 1221a and the first inner wall. When (11a) interferes, it can be seen as paths that overlap each other.

In order for the connection portion 1222a to sufficiently undergo elastic deformation, it may be necessary to secure a sufficient length of the area where the cut portion 1211a is cut. For example, the length of the area where the incision part 1211a is cut in the third direction (Z) is three times the length in the first direction (X) where the interference part 1221a and the first inner wall 11a overlap. It can be arranged to be more than that. However, the relationship between the length of the area where the cut portion 1211a is cut and the overlap length between the interference portion 1221a and the first inner wall 11a is not limited to this, and the elastic protrusion 1220a can be formed in various ways. .

With the above configuration, the elastic protrusion 1220a can be provided to enable elastic deformation when pressed by the first inner wall 11a. However, the configurations described above are merely examples for enabling elastic deformation as the elastic protrusions of the ice maker case are pressed in the ice maker for a refrigerator according to the spirit of the present disclosure. The configuration for allowing the elastic protrusion 1220a to be elastically deformable is not limited to this and may be provided in various ways. Some examples of various embodiments in which the elastic protrusion 1220a is provided to be elastically deformable will be described later (see FIGS. 18 to 20, etc.).

A plurality of elastic protrusions 1220a may be provided on the ice maker case wall 1210a. In other words, a plurality of first elastic protrusions 1220a may be provided on the first ice maker case wall 1210a. A plurality of second elastic protrusions 1220b may be provided on the second ice maker case wall 1210b. Hereinafter, the description will be made based on the first ice maker case wall 1210a and the first elastic protrusion 1220a, and the following description will equally apply to the configuration of the second ice maker case wall 1210b and the second elastic protrusion 1220b. You can.

The plurality of elastic protrusions 1220a may be arranged in the vertical direction. The plurality of elastic protrusions 1220a may include an upper elastic protrusion 1220aa and a lower elastic protrusion 1220ab formed below the upper elastic protrusion 1220aa.

The upper elastic protrusion 1220aa may be provided on the upper part of the ice maker case wall 1210a. The lower elastic protrusion 1220ab may be provided at the lower part of the ice maker case wall 1210a.

When the first holder 11aa supports the upper part of the ice maker case 1200, the first holder 11aa may be disposed at least adjacent to the upper elastic protrusion 1220aa. It is not limited thereto, and the first holder 11aa may be placed in various positions.

The upper elastic protrusion 1220aa may be disposed below the first holder 11aa. However, the present invention is not limited thereto, and as an example, the upper elastic protrusion 1220aa may be disposed above the first holder 11aa. As an example, the first holder 11aa may be disposed between the upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab. As an example, the lower elastic protrusion 1220ab may be disposed above the first holder 11aa.

The upper elastic protrusion 1220aa and the lower elastic protrusion 1220ab may be formed to have different shapes.

For example, as shown in FIG. 12, the length of the lower elastic protrusion 1220ab extending in the second direction (Y) may be longer than the length of the upper elastic protrusion 1220aa extending in the second direction (Y). there is. However, it is not limited thereto, and as an example, the length of the lower elastic protrusion 1220ab extending in the second direction (Y) may be shorter than the length of the upper elastic protrusion 1220aa extending in the second direction (Y). . As an example, the length of the lower elastic protrusion 1220ab extending in the second direction (Y) may be formed to correspond to the length of the upper elastic protrusion 1220aa extending in the second direction (Y).
