The lever head 372 has a disk shape of a predetermined size as shown, and is formed to protrude upward from the end of the lever support portion 370.

13 to 15 show the mounting state of the bucket 210 in more detail. That is, the mounting state of the bucket 210 is shown in Figure 13, Figure 14 is a cross-sectional view taken along the line A-A 'shown in FIG. In addition, FIG. 15 illustrates a state in which the water tank 210 is separated from the ice making case 202.

As shown in these figures, the bucket 210 is mounted on the upper end of the ice making case 202 is fixed so as not to be removed. Accordingly, the ice making assembly 200 includes mounting guide means 400 for guiding the water tank 210 to be easily seated on the ice making case 202, and a water tank 210 mounted on the ice making case 202. A departure prevention means 410 for preventing the departure is further provided.

The mounting guide means 400 is composed of a mounting guide 402 and a guide protrusion 404 and the like are formed to be coupled to each other in the ice making case 202 and the bucket 210, respectively. That is, the mounting guide 402 protruding inward is integrally formed on the side inner wall of the ice making case 202, and the guide protrusion 404 protruding laterally on the outer side of the bucket body 210 ′ of the bucket 210. ) Is integrally formed.

The mounting guide 402 may include a protrusion accommodating part 402 ′ in which the guide protrusion 404 is inserted and accommodated, and a protrusion guide part for guiding the guide protrusion 404 to the protrusion accommodating part 402 ′ ( 402 ") and the like.

The protrusion accommodating part 402 'has a' U 'shape as shown in the drawing, and the protrusion guide part 402' is integrally formed on an upper end of the protrusion accommodating part 402 '. The guide portion 402 ″ has a 'V' shape in which a gap between both ends gradually widens upward. Therefore, the mounting guide 402 has a shape in which the 'U' and the 'V' are combined as a whole.

On the other hand, the guide protrusion 404 is formed with a relatively larger length than the upper and lower widths, the lower surface is formed to have a rounded curvature. That is, as shown, the lower end of the guide protrusion 404 is formed in a semi-circular shape with a central portion protruding downward.

Therefore, when the bucket 210 is mounted on the ice making case 202 from above, the bottom surface of the guide protrusion 404 slides the protrusion guide part 402 ″ to the protrusion receiving part 402 ′. To be guided.

The detachment preventing means 410 is formed in a shape corresponding to each other in the ice making case 202 and the bucket 210 is composed of a separation prevention jaw 412 and the locking ribs 414 and the like interfere with each other.

The release prevention jaw 412 protrudes inward from the inner side wall of the ice making case 202, and the locking rib 414 protrudes outward from the side outer wall of the bucket 210. And, the end of the separation prevention jaw 412 and the locking rib 414 is formed in a streamlined shape to have a rounded curvature.

Looking in more detail with reference to Figure 14, the protrusion height (①) of the separation prevention jaw 412 has a size smaller than the inner protrusion height of the mounting guide 402, as well as when the bucket 210 is mounted It is formed to have a size smaller than the distance (②) between the side inner wall of the ice making case 202 and the guide protrusion 404.

Thus limiting the lateral protrusion height of the departure prevention jaw 412 is to prevent the departure prevention jaw 412 does not interfere with the detachment of the bucket (210). That is, the guide protrusion 404 and the departure prevention jaw 412 does not interfere with each other when the bucket 210 is attached and detached.

On the other hand, as shown in Figure 14, the separation prevention jaw 412 and the locking rib 414 is formed so that the end portion is in contact with each other. Therefore, when a predetermined or more upward force is applied to the bucket 210, the locking rib 414 is moved up and down of the separation preventing jaw 412.

More specifically, FIG. 14 shows a state in which the water tank 210 is mounted on the ice making case 202. At this time, the separation prevention jaw 412 and the locking rib 414 interfere with each other. Since the locking ribs 414 are located below the release preventing jaw 412, the above-mentioned separation of the water tank 210 is prevented.

That is, in the state in which the water tank 210 is mounted on the ice making case 202, the interference lever 222 pushes the opening / closing lever 212 upwards, and in this case, the water tank 210 is separated upward. Since the locking rib 414 is located below the release preventing jaw 412, the bucket 210 is prevented from being separated upward.

However, since the fixing force due to the interference between the locking ribs 414 and the separation prevention jaw 412 is not large, when the user pulls the bucket 210 upward, the locking ribs 414 are bent in a predetermined portion. Sliding with the departure stop 412 is moved to the upper side of the departure stop 412. Therefore, the bucket 210 is to be separated from the ice making case 202.

On the contrary, when the bucket 210 is pushed downward, the locking ribs 414 which are positioned above the release barrier 412 are bent and slide with the end of the release barrier 412 to allow the release barrier 412 to slide. It moves to the lower side of 412 and becomes the state as shown in FIG.

In this way, the separation prevention means 410 composed of the locking rib 414 and the separation prevention jaw 412 is formed so as not to function when a force of a predetermined size or more is applied. That is, when the interference lever 222 is applied with a force larger than the force pushing up the opening and closing lever 212 upward, the separation preventing means 410 is preferably configured to lose the function.

Hereinafter, the operation of the ice making assembly of the refrigerator having the configuration as described above will be described.

First, water must be supplied to the ice making assembly 200 from the outside. In this case, the freezing chamber door 100 is opened as shown in FIG. 4, and then the upper end of the ice making case 202 is opened to the water tank 210. To the outside.

That is, when the user pulls upwards by a predetermined force or more upward while holding the water tank 210, as shown in FIG. 14, the locking ribs 414 positioned below the separation prevention jaw 412 are bent and the separation prevention jaw 412. Since it moves to the upper side of the, the bucket 210 is separated from the ice making case 202.

Then, water is introduced into the water tank 210 divided into two parts, and the water tank 210 in which the water is built is returned to the inside of the ice making assembly 200 again.

At this time, when the bucket 210 is in the original position, the opening and closing lever 212 is moved upward by the interference lever 222. As such, when the opening and closing lever 212 moves upward, the water supply port 214 is opened so that the water in the bucket 210 falls downward.

In more detail, when the water tank 210 is separated from the ice making case 202, the opening and closing cap 362 shields the water supply port 214. Therefore, in this state, water is stored and stored in the bucket 210.

Next, the water tank 210 is mounted on the upper end of the ice making case 202 in a state where water is stored in the water tank 210. At this time, the bucket 210 is guided by the mounting guide means (400).

More specifically, as shown in FIG. 15, when the water tank 210 is lowered from the upper side of the ice making case 202, the lower end portion of the guide protrusion 404 is the protrusion guide portion 402 ″ of the mounting guide 402. In order to slide in contact with the center) to move to the center portion, the guide projection 404 is subsequently inserted into the projection receiving portion (402 ') is accommodated.

At the same time, the locking ribs 414 cause interference with the separation preventing jaw 412. The locking ribs 414 are bent by the load of the bucket 210 and the downward force applied by the user, and the upper locking ribs 414 are bent. 414 moves to the lower side of the departure prevention jaw 412 is in a state as shown in FIG.

In this case, the mounting of the water tank 210 is completed, and the water tank 210 is fixed without being separated upward again.

When the water tank 210 is mounted to the ice making case 202 by the above process, the water supply port 214 is opened. That is, when the water tank 210 is mounted, the contact rib 354 of the open / close lever 212 contacts the upper surface of the lever head 372 of the interference lever 222 (see FIGS. 10 to 12).

Accordingly, the interference lever 222 pushes the front end of the open / close lever 212, that is, the front end (right end in FIG. 11) of the contact rib 354 upward. In this case, the tip (right end in FIG. 11) of the opening / closing rib 360 which is integrally formed with the contact rib 354 is also bent upward. That is, the opening and closing lever 212 is formed long before and after, and has its own elasticity, so when the front end portion is pushed upward, the front end portion is bent by moving the upper end with the shaft.

As such, when the front end of the opening / closing rib 360 moves upward, the opening / closing stopper 362, which is blocking the water supply opening 214, moves upward and the water supply opening 214 is opened. In this case, the water inside the bucket 210 through the water supply port 214 is lowered to be supplied to the ice tray 224.

The water dropped from the bucket 210 is filled in the upper tray 224 ′ and the heart ray 224 ″, respectively. When water is supplied to the bucket 210 as described above, the bucket 210 of the bucket 210 is filled with water. Water automatically falls into the ice tray 224.

As described above, after the water is supplied to the ice making assembly 200 from the outside, the user closes the freezer door 100. In this case, water accumulated in the ice tray 224 is frozen by the cold air in the freezer compartment, thereby producing ice.

When ice occurs in the ice tray 224 to generate ice, the user opens the freezer door 100 again, and pulls the ice lever 240 downward. In this case, the ice tray 224 is twisted and rotated, at which time the ice cubes fall into the ice bank 230.

After the ice is dropped into the ice bank 230 by the above process, the user closes the freezer door 100 and opens the home bar door 120 whenever necessary to open the ice in the ice bank 230. It will be able to withdraw to the outside.

Referring to Figures 5 to 16 look at the process of withdrawing the ice stored in the ice bank 230 to the outside in more detail as follows.

First, the user pushes the top of the home bar door 120 to the rear side. In this case, the fastening hook 124 fixed by the hook fixing body 126 is released from the hook fixing body 126, so that the groove bar door 120 is opened to be in a state as shown in FIG.

In more detail, as the home bar door 120 rotates forwardly (clockwise in FIG. 5) about the lower door hinge 122, the connection link 260 also watches in an upright state as shown in FIG. 6B. Direction of rotation.

As the connection link 260 rotates in the clockwise direction (FIGS. 5 to 6b), the bank support plate 250 connected to the connection link 260 is also forward (right side in FIGS. 5 to 6b). Will be moved to. That is, since the vertical length of the connection link 260 is relatively shorter than the vertical length of the groove bar door 120, when the groove bar door 120 is opened completely horizontally as shown in FIG. 16, the bank support plate 250 Is to be moved a portion forward (right in Figures 5-6B).

As such, when the bank support plate 250 moves forward (right side in FIGS. 5 to 6B), the ice bank 230 placed on an upper surface of the bank support plate 250 also front (right side in FIGS. 5 to 6B). Will be moved to. Thus, a portion of the tip of the ice bank 230 is exposed to the front outside of the freezer door 100 (see FIG. 16).

At this time, since the fixing protrusion 232 formed on the bottom surface of the ice bank 230 is accommodated in the fixing groove 258 formed in the bank support plate 250, the ice bank (230) is drawn out in front of the bank support plate 250. 230 is simultaneously drawn out forward without sliding, and at this time, the moving roller 256 formed at the rear end of the bank support plate 250 may allow the bank support plate 250 and the ice bank 230 to move forward more easily. Done.

By the above process, after the portion of the ice bank 230 is exposed to the outside as shown in Figure 16, the user can immediately take the ice inside the ice bank 230, to take more ice In this case, the ice bank 230 is further drawn out.

In more detail, when the user applies a force forward while holding the front handle 234 of the ice bank 230 in the state as shown in Figure 16, the ice bank 230 is the upper surface of the bank support plate 250 It is pulled forward while sliding.

At this time, the user is more preferably pulled forward while lifting the front end portion of the ice bank 230 by a predetermined portion while holding the front handle 234. That is, since the fixing protrusion 232 of the ice bank 230 is inserted into the fixing groove 258 of the bank support plate 250 as shown in Figure 6b, slightly lift the tip of the ice bank 230 When the force is applied forward in the state, the fixing projections 232 will be out of the fixing grooves 258, so that the withdrawal of the ice bank 230 will be possible with less force.

After extracting the ice inside the ice bank 230 as described above, the ice bank 230 is returned to its original position. In this case, the ice bank 230 is reversed.

That is, in this case, the ice bank 230 is pushed backward so that the fixing protrusion 232 at the bottom of the ice bank 230 is accommodated in the fixing groove 258 of the bank support plate 250. In this case, the state as shown in FIG. 16 is obtained.

At this time, the tip of the home bar door 120 is lifted to close the home bar door 120. That is, the fastening hook 124 is inserted into the hook fixing body 126 by pushing the upper end of the groove bar door 120 backward. In this case, since the hook fixing body 126 fixes the fastening hook 124, the home bar door 120 is maintained in a closed state as shown in FIG.

Of course, at this time, the connection link 260 is also standing upright with the uprights of the home bar door 120, and at the same time the bank support plate 250 is pushed back (left in Figs. 5 to 6b) and It is in the same state.

In addition, the ice bank 230 may be withdrawn to the rear (left in FIG. 5). That is, when the freezing chamber door 100 is opened and the rear handle 236 of the ice bank 230 is pulled by the hand, the ice bank 230 slides the upper surface of the bank support plate 250. While being pulled out backward.
