A discharge port 86 (fig. 13) is formed at a lower portion of the ice bucket 80 to discharge the stored ice, and the ice discharged from the ice bucket 80 may be transferred to the distribution space 92 through the chute 91.

With this configuration, a user can access the ice making chamber 40 only by opening the ice making chamber door 36 without opening the storage chamber door 30. Accordingly, ice may be easily taken out of the ice bucket 80, and the ice bucket 80 may be easily repaired, cleaned, and replaced by separating the ice bucket 80 from the ice making compartment 40. Further, when the user approaches the ice making chamber 40, the storage chamber door 30 may be kept closed, thereby preventing cool air from leaking out of the storage chamber 21 and saving energy.

The storage compartment door 30 may include a dispenser 90 to provide water and ice to a user.

Fig. 5 is a bottom perspective view illustrating an ice making compartment of the refrigerator of fig. 1. Fig. 6 is a perspective view illustrating an ice maker of the refrigerator of fig. 1. Fig. 7 is an exploded perspective view illustrating an ice maker of the refrigerator of fig. 1. Fig. 8 is a view illustrating a structure in which an ice making tray of the refrigerator of fig. 1 is supported and fastened to a guide rib. Fig. 9 is a view illustrating a structure in which a motor case and coupling ribs of the refrigerator of fig. 1 are fastened by fastening members. Fig. 10 is a front view illustrating a state in which an ice maker is assembled into an ice making compartment of the refrigerator of fig. 1.

As shown in fig. 3 to 4, the ice making compartment 40 includes an ice making compartment wall 41 and an ice making space 47 formed by the ice making compartment wall 41. Ice making chamber wall 41 may include an upper wall 42, a lower wall 43, a left wall 44, a right wall 45, and a rear wall 46. The ice making space 47 may be formed such that a front surface thereof is opened.

The ice making chamber 40 includes a guide rib 50 for supporting the ice making tray 61. Although the present embodiment and the drawings show that the guide rib 50 is provided on the right wall 45 of the ice making compartment 40, on the contrary, the guide rib 50 may be provided on the left wall 44 of the ice making compartment 40.

The guide rib 50 may support one end portion of the ice making tray 61 in the longitudinal direction. The guide rib 50 may serve to guide the position of the ice making tray 61 when fastening a fastening member S1, which will be described later.

The guide rib 50 may be formed to extend in the front-rear direction. The guide rib 50 may be integrally formed with the ice making chamber wall. Alternatively, the guide rib 50 may be separately formed and attached to the ice making chamber wall.

The ice maker 60 may include an ice making tray 61 having an ice making unit 63 disposed to receive water, an ejector 70 rotatably disposed to separate ice cubes from the ice making unit 63, an ice separating motor 74 (fig. 14) disposed to rotate the ejector 70, a motor case 75 disposed to receive the ice separating motor, side covers 71 attached to sides of the ice making tray 61, a lower cover 72 attached to a lower portion of the ice making tray 61, and a detection lever 73 disposed to detect whether the ice bucket 80 is filled with ice cubes. With this structure, the ice maker can automatically perform a series of operations such as water supply, cooling, ice separation, and ice level detection.

Specifically, the ice making tray 61 may include a plurality of ice making cells 63, partitions 64 partitioning the plurality of ice making cells 63 from each other, and a cell part 62 having a passage groove 65 formed on the partitions 64 to allow water to flow between the partitions 64. The ice making tray 61 may include a pocket portion 66, and the pocket portion 66 is disposed at one side of the unit portion 62 in the longitudinal direction to receive water to be supplied to the ice making unit 63.

The ice making tray 61 may include a guide flange 67 protruding from one end of the unit portion 62 in the longitudinal direction to be supported on the guide rib 50 of the ice making compartment 40. The guide flange 67 may be positioned below the pocket portion 66.

The guide flange 67 may include a support portion 68 placed on the upper surface 51 (fig. 10) of the guide rib 50 to support the load of the ice making tray 61, and a stopper portion 69 interfering with the front surface 52 of the guide rib 50 to limit the entering distance of the ice making tray 61. The stopper portion 69 may extend downward from the front end of the support portion 68.

The guide flange 67 may be integrally formed with the unit portion 62. However, the guide flange 67 may be separately formed and coupled to the unit portion 62.

With this configuration, when the ice maker 60 is assembled into the ice making chamber 40, the guide flange 67 of the ice making tray 61 is first placed on the guide rib 50, and a fastening member S1, which will be described later, is fastened, so that the ice maker 60 can be fixed.

The motor case 75 may protect the ice separating motor by accommodating the ice separating motor. The motor case 75 may be coupled to one end of both ends of the ice making tray 61 in the longitudinal direction where the guide flange 67 is not formed.

The motor case 75 may include: a motor case outer wall 76 having a motor accommodating space 77 formed therein; and a coupling bracket 78 protruding from the motor case outer wall 76 to be coupled to the ice making chamber wall 41. The coupling bracket 78 may be provided with a through hole 79, and the fastening member S1 passes through the through hole 79. The fastening member S1 may include a screw, bolt, pin, rivet, or the like.

Motor case 75 may be fastened to upper wall 42 of ice making chamber wall 41. This is because the ice maker 60 is disposed at an upper portion of the ice making compartment 40, and the coupling of the motor case 75 with the upper wall 42 instead of the

side walls

44 and 45 has convenience in assembly work.

When the motor case 75 is fastened to the ice making compartment upper wall 42, the fastening member S1 may be fastened obliquely rearward in an upward direction. That is, as shown in fig. 9, the direction D in which the fastening member S1 is fastened and the inner surface 42a of the upper wall of the ice making compartment may have an inclination of a predetermined angle θ. This is because fastening in the oblique direction when fastening the fastening member S1 is more convenient for assembly than fastening from the bottom in the vertical direction. For this reason, the coupling bracket 78 of the motor case 75 may be formed to be inclined toward the front upper side. The coupling bracket 78 may be integrally formed with the motor case outer wall 76.

The motor case 75 may have a guide groove 76a formed below the coupling bracket 78. The fastening member S1 can be easily guided to the coupling bracket 78 through the guide groove 76 a. A part of the corner of the motor case 75 is recessed to form an inclined surface 76b, and a guide groove 76a may be formed between the inclined surface 76b and the coupling bracket 78.

The ice making compartment 40 may include a coupling rib 55, the coupling rib 55 being provided to allow the coupling bracket 78 to be supported and to allow the fastening member S1 to be inserted. The coupling rib 55 may be formed on the ice making compartment upper wall 42 to protrude toward the ice making space 47.

The coupling bracket 78 is in close contact with the front surface 56 of the coupling rib 55, and therefore, the front surface 56 of the coupling rib 55 may also be inclined at an angle corresponding to the coupling bracket 78. The coupling rib 55 may have an insertion hole 57 into which the fastening member S1 is inserted into the insertion hole 57. A thread may be formed on an inner circumferential surface of the insertion hole 57 to correspond to a thread of an outer circumferential surface of the fastening member S1.

It is appropriate that the coupling bracket 78 and the coupling rib 55 be formed at a position distant from the ice-making unit area a (fig. 6), which is substantially an upper area of the ice-making unit 63. This is to prevent the fastening member S1 from falling into the ice making unit 63 when the operator accidentally drops the fastening member S1 during the work of fastening the coupling bracket 78 and the coupling rib 55 by the fastening member S1.

The ice making tray 61 may also be fastened to the ice making chamber wall 41. Specifically, the guide rib 50 is formed with an insertion hole 53 into which the fastening member S2 is inserted, and the guide flange 67 of the ice making tray 61 is formed with a through hole 69a through which the fastening member S2 passes, so that the ice making tray 61 can be fastened to the ice making chamber wall 41 by the fastening member S2.

However, unlike the present embodiment, the fastening member S2 may be omitted. That is, only the motor case 75 may be fastened to the ice making chamber wall 41.

Fig. 11 is a front view illustrating a state in which an ice maker according to another embodiment of the present disclosure is assembled into an ice making compartment of a refrigerator.

An ice maker assembling structure of a refrigerator according to another embodiment of the present disclosure will be described with reference to fig. 11. The same reference numerals are assigned to the same components as in the above-described embodiment, and the description thereof may be omitted.

In the above embodiment, the guide rib 50 is provided on the right wall 45 of the ice making compartment 40, but the guide rib 250 may be additionally provided on the left wall 44 of the opposite side of the ice making compartment 40. The guide ribs 250 may support the motor case 75. A through hole through which the fastening member S3 passes may be formed on the guide rib 250, and an insertion hole into which the fastening member S3 is inserted may be formed on the motor case 75.

Fig. 12 is a perspective view illustrating an ice bucket of the refrigerator of fig. 1. Fig. 13 is an enlarged view of a portion of fig. 3. Fig. 14 is a plan view illustrating an ice making tray and a falling ice guide of the refrigerator of fig. 1. Fig. 15 is a plan view illustrating a structure in which a plurality of the ice dropping guides of fig. 14 are provided.

An ice dropping guide according to an embodiment of the present disclosure will be described with reference to fig. 12 to 15.

According to the embodiment of the present disclosure, the bottom surface 85 of the ice bucket 80 has a high end portion 85a and a low end portion 85b, and may be formed to be inclined from the high end portion 85a to the low end portion 85 b. The high end portion 85a may be positioned adjacent to the storage compartment door 30, and the low end portion 85b may be positioned adjacent to the ice making compartment door 36.

In this structure, when ice generated in the ice maker 60 falls into the ice bucket 80, a large impact may occur in the case where the ice falls into the lower end portion 85 side of the bottom surface 85. Therefore, a large noise may occur and the ice may be damaged.

According to an embodiment of the present disclosure, the refrigerator 1 may include an ice dropping guide 100 for guiding ice dropped from the ice maker 60 to a high end portion 85a side of the bottom surface 85 of the ice bucket 80 in order to reduce ice dropping noise and ice crushing.

The ice dropping guide 100 may be positioned below the ice making tray 61 and adjacent to the ice making chamber door 36.

Specifically, the ice dropping guide 100 may be integrally formed with the ice bucket 80. The ice dropping guide 100 may protrude from the front surface portion 81 of the ice bucket 80 to the ice storage space 87 side of the ice bucket 80. The ice drop guide 100 may be inclined downwardly from the front end 101 to the rear end 102.
