The wire connected to the motor assembly 280 and the wire connected to the driving source 220 are connected to the second connector 282. The second connector 282 is detachably connected to the first connector 125.

In detail, the support mechanism 250 includes a first support part 252 and a second support part 260 coupled to the first support part 252.

The first support part 252 is seated in the ice making chamber 120. The motor assembly 280 is mounted on the first support part 252. In addition, an ice opening 253 through which the ice discharged from the ice bin 300 passes is formed at the bottom surface of the first support part 252. The ice bin 300 is seated on the first support part 252. That is, the first support part 252 supports the ice bin 300.

When the ice bin 300 is seated on the first support 252, the motor assembly is connected to the ice bin 300. In the present embodiment, the state in which the ice bin 300 is seated on the first support part 252 means a state in which the ice bin 300 is accommodated in the ice making chamber 120.

7 is a cross-sectional view taken along AA of FIG. 2, FIG. 8 is an enlarged view of a portion B of FIG. 7, and FIG. 9 is a view illustrating a state in which the ice maker is rotated to separate ice from the ice maker in FIG. 7. to be.

7 to 8, in the state where the ice making assembly 200 is disposed in the ice making chamber 120, the ice bin 300 is disposed substantially below the ice maker 210.

In detail, the inlet 301a of the opening 310 of the ice bin 300 is located lower than the lower surface of the ice maker 210. Accordingly, the ice bin 300 is disposed in an area A between the ice making room door 130 and the ice maker 210 with the ice making door 130 closing the ice making room 120. It doesn't work. That is, the ice bin 300 may be disposed in an area excluding the area between the ice making room door 130 and the ice maker 210 among the entire areas of the ice making room 120.

The reason is that the ice maker 210 is inverted by the rotation operation, and the ice is separated from the ice maker 210 and dropped to the ice bin 300 by its own weight, so that the ice in the area A is This is because the bean does not have to be located. That is, since the ice from which the ice is separated from the ice maker 210 does not pass through the region A, the ice bin 300 does not need to be located in the region A.

Accordingly, as the ice bin 300 is not positioned in the area A, the ice making room door 130 may be disposed closer to the ice maker 210, and thus the refrigerating room door 11 ) Can reduce the overall thickness. That is, the refrigerator compartment door may be slim.

Meanwhile, the ice bin 300 includes one or more rotating blades 410 and one or more fixed blades 480. Ice stored in the ice bin 300 may be crushed by the interaction of the rotating blade 410 and the fixed blade 480.

In order to easily crush the ice, the ice bin 300 may be provided with a plurality of rotating blades 410 and a plurality of fixed blades 480.

The ice bin 480 includes a discharge port 510 for discharging the barrel ice or the crushed ice. The discharge port 510 is located below the blades 410 and 480.

The plurality of rotating blades 410 is fixedly installed on the rotating shaft 420. The rotating shaft 420 may extend in the front-rear direction (horizontal direction) of the refrigerating compartment door 11 and may be connected to the motor assembly (see 280 of FIG. 6).

The plurality of rotating blades 410 are spaced apart from each other in a direction parallel to the extending direction of the rotating shaft 420. The plurality of rotating blades 410 and the plurality of fixed blades 480 are alternately arranged in a direction parallel to the extending direction of the rotating shaft 420.

One side of the plurality of fixed blades 480 is connected to the rotation shaft 420. That is, the rotation shaft 420 passes through the plurality of fixed blades 480. The other side of the plurality of fixed blades 480 is fixed to the ice bin 300.

By the motor assembly (see 280 of FIG. 6), the rotation shaft 420 may be rotated in both directions. When the rotating shaft 420 is rotated in one direction, the plurality of rotating blades 410 is rotated toward the plurality of fixed blades 180. Then, after the ice is crushed is discharged through the discharge port 510. On the other hand, when the rotating shaft 420 is rotated in the other direction, the ice is discharged through the discharge port 510 in the pulverized state.

On the other hand, the inside of the refrigerating compartment door 11 is provided with a plurality of different types of heat insulating materials for insulating the refrigerating compartment and the outside. The plurality of heat insulating materials include a first heat insulating material 116 and a second heat insulating material 117. The first insulation 116 is a vacuum insulation panel (VIP) (or a vacuum insulation panel), and the second insulation 117 is a polyurethane foam insulation (Expanded Poly Styrene (EPS)).

The first heat insulator 116 is disposed between the recessed surface 112a and the outer case 111 to form the ice making chamber 120 of the door liner 112. In this case, since the ice bin 300 is provided in the ice making chamber 120, the first heat insulating material 160 may be described as being disposed between the outer case 111 and the ice bin 300. .

In addition, since the first heat insulating material 116 is disposed between the recessed surface 112a and the outer case 111, the first heat insulating material 116 is located in front of the ice bin 300. It may be explained.

In addition, the vertical length of the first heat insulating material 116 may be equal to or longer than the vertical length of the ice bin 300. Preferably, the vertical length of the first heat insulating material 116 may be equal to or longer than the vertical length of the ice making chamber 120. The reason is that the upper and lower lengths of the first heat insulating material 116 may be equal to or longer than the upper and lower lengths of the ice making chamber 120, so that the insulation between the ice making chamber 120 and the outside may be effectively performed.

The first heat insulating material 116 may be fixed to the outer case 111. For example, the first heat insulating material 116 may be attached to the inner surface of the outer case 111 by the adhesive 118.

Accordingly, the cross section of the refrigerating compartment door 130 on the side where the ice making chamber 120 is formed may include an outer case 111, an adhesive 118, a first insulation 116, a second insulation 117, and a door liner. 112) in order. At this time, in order to prevent heat transfer in the front-rear direction, the first heat insulator 116 and the second heat insulator are disposed in the front-rear direction to form a layer.

The vacuum insulation material may include a core material formed by compressing glass fibers and an outer cover material surrounding the core material. In detail, glass fibers are dispersed in an inorganic binder, and then a plurality of glass fiber boards manufactured by a papermaking method are laminated to form a core material. Next, an outer cover material having a laminated structure of a surface protective layer, a metal barrier layer and an adhesive layer is formed. Next, a quicklime (CaO) powder is packaged in a pouch to form a getter. Next, the getter is attached to the upper portion of the core material, or inserted into the surface of the core material, the envelope material is formed into an encapsulation member, and the core material is enclosed in the encapsulation member to seal in a vacuum state to complete a vacuum insulator.

In more detail, the core material, a plurality of 4 ~ 10mm glass fiber board (Glass Fiber Board) is laminated. Here, the glass fiber board (Glass Fiber Board) is produced by dispersing the glass fiber (Glass Fiber) in the inorganic binder, the glass fiber is preferably used short fibers having a diameter of 0.1 ~ 10㎛. In addition, it is preferable to use the water glass which consists of water, a silica powder, and sodium hydroxide (NaOH) as an inorganic binder.

At this time, by using the papermaking method, it is possible to form a glass fiber board having excellent heat insulation board characteristics while having a porosity of 80% or more. In addition, when the diameter of the glass fiber is less than 0.1㎛ particles may be too small to form the board shape normally, if the diameter exceeds 10㎛ the pore diameter of the glass fiber board exceeds 20㎛ to reduce the thermal insulation properties do.

The envelope agent is formed by sequentially forming an adhesive layer and a metal barrier layer and a surface protective layer formed on the adhesive layer.

Here, the adhesive layer performs a function of maintaining the vacuum state as a layer that is thermally welded to each other by heat sealing. Therefore, the adhesive layer is easy to heat weld high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), unstretched polypropylene (CPP), stretched polypropylene (OPP), polyvinylidene chloride (PVDC) ), Polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), ethylene-vinyl alcohol copolymer (EVOH), formed of at least one thermoplastic plastic film, but having a sufficient sealing property of 1 ~ 100㎛ It is preferable to form in thickness.

Next, a metal thin film having a thickness of 6 to 7 μm is formed on the adhesive layer as a barrier layer for gas blocking and core material protection. In this case, in general, an Al foil metal barrier layer may be used. At this time, Al may be a metal material, so there may be a problem such as cracking when folded. In order to prevent this, the surface protection layer may be provided on the metal barrier layer.

The surface protective layer of the shell material is preferably formed of a laminated structure of a polyethylene terephthalate film (PET) of 10 ~ 14㎛ thick and nylon (Nylon) film of 20 ~ 30㎛. In this case, when the cracks generated in the metal barrier layer are serious, damage may also be applied to the polyethylene terephthalate / nylon film. To prevent this, a vinyl resin layer is coated on the polyethylene terephthalate layer. .

The getter includes a pouch containing quicklime (CaO). The use of quicklime powder of 95% or higher purity, but also the pouch is formed of wrinkled paper and polypropylene (PP) impregnated non-woven fabric to ensure more than 25% moisture absorption performance. At this time, the thickness of the getter in consideration of the thickness of the entire thermal insulation pad is preferably formed within 2mm.

In the case of the vacuum insulation material as described above, by using a core material having a porosity of 80% or more and a pore diameter of 20 μm or less, it is possible to maximize the thermal insulation performance, it is possible to obtain a thermal insulation effect several times more than the conventional polyurethane foam insulation.

The thermal conductivity of the polyurethane foam insulation is approximately 0.03 kcal / mhr ° C., the thermal conductivity of the vacuum insulation is approximately 0.002 ~ 0.006 kcal / mhr ° C.

Therefore, when the thickness of a single polyurethane foam insulation is T1, when the total thickness of the vacuum insulation and the polyurethane foam insulation is maintained at T1 there is an advantage that the thermal insulation performance is significantly improved.

In the present embodiment, since the ice making chamber 120 should be maintained at 0 degrees or less similarly to the freezing chamber 104, when the vacuum insulator 116 is disposed on the refrigerating chamber door side where the ice making chamber 120 is formed, At the same time the insulation of the ice-making chamber is effective and the thickness of the refrigerating compartment door 11 can be reduced.

That is, since the thickness between the recessed surface 112a for forming the ice making chamber 120 and the outer case 111 is reduced, the thickness of the portion of the ice making chamber 120 side in the refrigerating compartment door 11 is reduced. It becomes possible.

An opening (not shown) for injecting liquid for foaming may be formed in the refrigerating compartment door 11. After foaming is complete, the opening may be covered by an opening cover (not shown).

In addition, different types of first insulation 160 and second insulation 162 may be provided in the ice compartment door 130 to insulate the refrigerating compartment and the ice making compartment. The first heat insulating material 160 is a vacuum heat insulating material, and the second heat insulating material 162 is a polyurethane foam heat insulating material. The thickness of the ice making room door 130 may be reduced by the vacuum insulator.

Meanwhile, the inlet 301a of the ice bin 300, the discharge port 510 of the ice bin 300, the opening 253 of the first support part 250, and the opening 127 of the door liner 112. When the inlet 152 and the outlet 153 of the ice duct 150 overlap with each other, they have a common area overlapping each other. Thus, the movement path of the ice can be minimized.

Hereinafter, a description will be given of the movement of the ice generated in the ice making assembly.

When the operation signal is input to the driving source 220 to separate the ice from the ice maker 210, the driving source 220 is operated. Power of the driving source 220 is transmitted to the ice maker 210 by the gear box 224 is rotated the entire ice maker 210. In this embodiment, the ice is separated by the twisting operation of the ice maker 210. In the twisting operation of the ice maker 210, one end and the other end of the ice maker 210 are relatively moved, causing twisting, and the ice is separated from the ice maker 210. Since the twisting operation principle of the ice maker 210 is the same as the known content, a detailed description thereof will be omitted.

The ice separated from the ice maker 210 is dropped into the ice bin 300 through the inlet 301a of the opening 310 of the ice bin 300.

At this time, the falling direction of the ice separated from the ice maker 210 is a direction crossing with the extending direction of the rotating shaft 420. In another aspect, the falling direction of the ice separated from the ice maker 210 is substantially parallel to an imaginary surface drawn when the plurality of rotating blades 410 are rotated.

Some of the ice separated from the ice maker 210 is dropped into the plurality of rotating blades 410. In addition, in accordance with the rotation direction of the plurality of rotating blades 410, the ice cube or ice may be discharged.

As described above, since the ice in the ice bin is moved upwards and downwards, and the ice inside the ice bin is moved and dropped by the plurality of rotating blades, the thickness of the ice bin may be reduced.

In the present embodiment, the thickness of the ice bin 300 refers to the thickness of the ice bin in the extending direction of the rotation shaft 410.

The thickness of the refrigerating compartment door may be reduced by the reduction of the thickness of the ice bin and the location of the ice bin in the ice making chamber according to the method of separating the ice maker and the ice.

In addition, as the vacuum insulator is provided on the refrigerating compartment door, and the vacuum insulator is provided on the ice making chamber door, the thickness of the refrigerating compartment door can be further reduced.

When the thickness of the refrigerating compartment door is reduced, it is possible to install a basket for storing food in addition to the refrigerating compartment door.

In addition, if the thickness of the refrigerating compartment door is reduced, the volume of a portion of the refrigerating compartment door that is drawn into the refrigerating compartment is reduced, resulting in an increase in the storage capacity of the refrigerating compartment.

12 is a perspective view of a refrigerator according to a fourth embodiment, and FIG. 13 is a perspective view of the ice bin rotated in FIG. 12.

This embodiment is the same as the first embodiment in other parts, except that there is a difference in the position of the ice making assembly. Therefore, hereinafter, only characteristic parts of the embodiment will be described.

12 and 13, the refrigerator 80 of the present embodiment will be described using a bottom freezer type refrigerator as an example. In one of the refrigerator doors 820 and 830 of the present embodiment, an ice bin 860 is mounted, and the remaining configuration of the ice making assembly (ice maker 850, etc.) excluding the ice bin 860 is disposed in the refrigerator compartment 812. do. Hereinafter, an ice bin 860 is provided in the refrigerating compartment door 820 on the left side.

As described above, the refrigerating compartment door 820 may be provided with a vacuum insulator, and thus the detailed description may be omitted.

The refrigerator compartment 812 is provided with an insulation case 870 for insulation between the space where ice is formed and the refrigerator compartment 812. The ice maker 850 or the like is disposed inside the heat insulation case 870. In order for the ice generated by the ice maker 850 to fall downward, the bottom surface of the heat insulation case 870 may be opened.

The refrigerator compartment door 820 includes an outer case 820a and a door liner 820b. The door liner 820b is provided with a dike 821 for mounting the ice bin 860. The dyke 821 may be integrally formed with the door liner 820b or may be separately formed and coupled to the door liner 820b.

The dyke 821 includes an upper surface 823 in which an opening 823a is formed, and both side surfaces 822, a lower surface 824, and a rear surface 825. A sealer 823b may be provided in the opening 823a.

An upper surface may not be formed on the dyke 821, and a separate cover having an opening may be mounted on the dike 821 or coupled to an upper side of the ice bin 860 to cover the ice bin 860. .

In addition, the dyke 821 is provided with a mounting portion 826 for mounting the ice bin 860. The mounting portion 826 may be recessed toward the outer case 820a on the rear surface 825.

The ice bin 860 may be detachably mounted or rotatably connected to the mounting part 826. Of course, even if the ice bin 860 is rotatably mounted to the mounting portion, the ice bin 860 can be separated from the mounting portion 826. In FIG. 13, for example, the ice bin 860 is rotatably connected to the mounting unit 826.

Since the ice bin 860 is a region in which ice is stored, the space inside the ice bin 860 should be maintained at a temperature similar to that of the freezer compartment. That is, the refrigerating compartment 102 should be maintained at 0 degrees or more, and the region inside the ice bin 860 should be maintained at 0 degrees or less. The ice bin 860 is located in the refrigerating compartment 812 when the refrigerating compartment doors 820 and 830 close the refrigerating compartment 812, so that the ice bin 860 is insulated from the refrigerating compartment 812 and the ice bin 860. The ice bin 860 may include an insulated bin cover 862. Of course, since the ice bin 860 is accommodated in the dike 821, the dike 821 may perform a heat insulation function. That is, the dyke 821 may serve as a heat insulation case.

A filler 880 is provided at one side of the dyke 821. The filler 880 may prevent cold air from leaking between the refrigerator compartment doors 820 and 830 while the refrigerator compartment doors 820 and 830 are closed. A heater 882 may be provided inside the filler 880 to prevent frost from being caught in the filler 880.

On the other hand, in order to keep the ice stored in the ice bin 860 without melting, cold air must be supplied to the ice bin 860. Therefore, when the refrigerating compartment door 820 closes the refrigerating compartment 102, the ice bin 860 is positioned below the heat insulation case 870. Cold air in the insulation case 870 and the ice generated by the ice maker 850 are supplied to the ice bin 860.

A recovery flow path 827 is formed at the other side of the dike 821 to recover the cold air supplied to the ice bin 860, and a cold air recovery duct 814 is provided at the sidewall of the refrigerating chamber 812.
