At this time, the partition rib 11a of the ice making chamber 11 serves to divide the ice produced in the ice making chamber 11 into a predetermined size.

When ice is produced in this way, the heater 17 of the ice making apparatus is operated for a short time to melt the contact surface of the ice in contact with the surface of the ice making chamber 11. Subsequently, the heating of the heater is stopped by sensing the temperature of the ice maker mold 11b by the temperature sensor S, and as the ejector pin 14a is rotated by the motor unit, each ice placed in the corresponding space is discharged to the outside. . This ice is discharged to the ice bank 20.

When the ice bank 20 is filled with a predetermined amount of ice by repeating this series of processes, the ice making process of the ice maker 10 is terminated by the control unit. In addition, if it is determined that the ice is insufficient in the ice detection arm 18, the ice making process is performed again, and the ice maker 10 is filled with a predetermined amount of ice.

As described above, when the ice bank 20 is filled with ice, when the user selects a predetermined button on the control panel, the uncrushed ice (hereinafter referred to as vat ice) or crushed ice is discharged to the dispenser (not shown). Accordingly, the users can selectively obtain the bin ice and the crushed ice.

Referring to the accompanying drawings, the rotation control apparatus of the ice maker cover according to the embodiment of the present invention configured as described above is as follows.

Referring to FIG. 4, the refrigerator 200 is divided into a freezer compartment 201 and a refrigerating compartment 202, and doors 203 and 204 are installed to open and close the freezer compartment 201 and the refrigerating compartment 202. An ice maker 250 as illustrated in FIG. 2 is installed inside the door 203.

The ice maker 250 is installed inside the freezer compartment door 203, and is composed of an upper ice maker 210 for manufacturing ice and a lower ice bank 220 for storing manufactured ice.

An ice maker cover 270 having a predetermined radius is installed outside the ice maker 210 of the ice maker 210. The ice maker cover 270 is interlocked with the freezer compartment door 203 so that water does not leak from the ice making chamber inside the ice maker 210 to the outside. For example, the ice maker cover covers the ice maker when the freezer door is opened as shown in FIG. 4. Preferably, the ice maker cover 270 may be formed of a heat insulating material, and may cover the ice making cold air to be insulated on the inner space.

That is, when the freezer door 203 is opened, the ice maker cover 270 closes the ice maker 210 to prevent the water inside the ice maker from leaking to the outside. On the contrary, when the freezer door 203 is closed, the ice maker cover 270 is closed. Opening the ice maker 210 allows the freezer cold air to be supplied to the ice maker 270.

The structure in which the ice maker cover can be opened and closed is shown in FIG. 5.

Referring to FIG. 5, the ice maker cover 270 has a structure in which a plurality of hemispherical cases are combined, and an upper fixed cover 271 and a lower rotary cover 272 are combined, and a lower rotary cover 272 is an ice maker. When the cover 270 is closed, the cover 270 is formed into the inside of the fixing cover 271, and when the ice maker cover 270 is opened, the cover 270 is opened at a predetermined radius from the fixing cover 271.

In this case, one end of the fixed cover 271 is formed with the stop jaw 271a inward, and the rotary cover 272 is rotated by forming the stop jaw 272a corresponding to the stop jaw 271a at the other end outward. It limits the range of rotation of the cover 272. As another example, a stopper (not shown) may be formed at one end of the rotary cover 272 to limit the opening range.

In addition, the ice maker cover 270 has a configuration in which the radius of the rotary cover 272 is smaller than the radius of the fixed cover 271, thereby joining in and out. In another embodiment, the fixed cover 271 and the rotary cover 272 may have the same or different radii, and for example, the rotary cover 272 may be rotated to the outside of the fixed cover 272. .

In addition, the rotation radius of the ice maker cover 270 is larger than the ejector pin 214 in the ice making chamber, thereby not affecting the rotation operation of the ejector pin 214.

4 and 5, the ice maker cover 270 has a radius that covers only the ice making chamber 211 at a predetermined radius, or includes an ice maker 210 including both a motor part and an ice making chamber. It may have a radius to cover. Alternatively, the cylindrical ice maker mold 211 may be installed in a shape capable of covering only the cylindrical ice maker mold 211.

Rotating control means 260 is installed on one side of the ice maker cover 270 and one side of the ice maker to rotate the ice maker cover. This will be described with reference to FIGS. 6 and 7. 6 is a state in which the freezer compartment door is closed, and FIG. 7 is a state in which the freezer compartment door is open.

 As shown, the rotation control means 260 provided on one side of the ice maker cover 270 is composed of a vertical moving link 261 and a rotary link 262.

The vertical movement link 261 is inserted into and installed in the vertical movement groove 203b of the door liner 203a formed inside the freezer compartment door 203, thereby vertical movement link 261 according to opening and closing of the freezer compartment door 203. ) Will move up and down vertically. When the freezer compartment door is opened, the vertical movement link 261 is moved upward in the vertical direction to protrude outside the freezer compartment door, and when the freezer compartment door is closed, the vertical movement link 261 is moved vertically by the freezer compartment ceiling wall 201a.

Here, the vertical movement groove 203b includes, for example, a means for limiting the movement range of the vertical movement link 261, a limit for the vertical movement speed, and a movement limiting means for stopping the movement. Also preferably, the vertical moving link 261 is installed on one side of the door liner.

The rotary link 262 is mounted at the other end of the vertical movable link 261 and rotates in the rotation direction of the ice maker cover 270. The rotary link 262 rotates both connecting rods 263 and 264 about the central axis 265. The long long connecting rod 263 is connected to the other end of the vertical moving link 261 at the end, and the short connecting rod 264 is coupled to the rotation shaft 273 of the ice maker cover 270 at the end.

In addition, the central axis 265 may protrude on an extension line of the ice maker 210 or the ice bank 220.

As shown in FIG. 6, when the freezing compartment door 203 is closed, the rotation control means 260 moves in a vertical downward direction while one end of the vertical moving link 261 strikes the freezing chamber ceiling wall 201a. Here, one end of the vertical movable link 261 may be formed in a curved shape or formed in a free end so as to slide to the freezing chamber ceiling wall 203a.

At this time, the vertical movement link 261 rotates the rotary link 262 while moving downward. The rotary link 262 rotates about the central axis 265 and rotates the rotation shaft 273 of the ice maker cover 270 fixed at the end thereof. Accordingly, the rotary cover (see FIG. 5) of the ice maker cover 270 rotates to open the ice maker 210, thereby allowing a freezing chamber cold air to flow therein.

In another embodiment, the vertical movement link 261 may be configured with at least two sections or more for vertical movement, or may further include a horizontal movement link that rotates in a horizontal direction of the freezer door liner. In addition, a compression spring for vertically moving up and down by a predetermined compression and restoration operation may be installed below the vertical movement link 261.

As shown in FIG. 7, in order to close the ice maker 210 positioned above the ice maker 250 when the freezer compartment door 203 is opened, the vertical moving link 261 moves upward from the freezer compartment door 203 by a predetermined distance. Will move. In this case, the vertical movement link 261 in the vertical upward direction rotates the rotary link 262 about the central axis 265 while moving upward, thereby making an ice maker cover 270 fixed to an end of the rotary link 262. Rotation shaft 273 rotates in the direction of closing the ice maker. Accordingly, the rotation cover (see FIG. 5) of the ice maker cover 270 rotates to close the ice maker 210, thereby solving the problem of water falling in the ice making chamber.

For the rotation operation of FIGS. 6 and 7, the rotation link 262 is preferably coupled with elastic restoring means for providing a restoring force according to rotation.

8 is an embodiment providing a predetermined restoring force so that the rotational movement of the rotation control means 260 is possible.

Referring to FIG. 8, a tension spring 266 is installed at the long connecting rod 263 of the rotary link 262. The tension spring 266 is tensioned when the vertical movement link 261 moves in the vertical downward direction, and is restored to its original state when the vertical movement link 261 moves in the upward direction (circular direction). The closing force of the ice maker cover 270 can be adjusted more quickly by the restoring force of the tension spring 266.

Therefore, as the freezing compartment door 203 is opened, the tension spring 266 rotates the rotary link 262 rapidly in conjunction with the movement of the vertical movable link 261, thereby rotating the shaft 273 at the end of the rotary link. It can be moved quickly in the closed rotation, and the rotary cover of the ice maker cover 270 to close the ice maker.

The tension spring 266 has an opening and closing operation of the ice maker cover 270 too fast due to the tension and the restoring force, there is no problem when closing the ice maker cover 270 quickly, but if the ice maker cover 270 is opened too soon, It may leak into the freezer compartment.

In order to solve this problem, as shown in (a) (b) of FIG. 9, the other end of the long connecting rod 263 and one end of the short connecting rod 264 are provided with a connection spring 267 having weak elasticity. Here, the connection spring 267 functions as a buffer spring that buffers the transmission force of the long connecting rod 263.

The connecting spring 267 connects the long connecting rods 263 and the short connecting rods 264 with each other in order to prevent too fast closing rotation when the rotary cover 271 of the ice maker cover 270 is closed. It acts as a buffer.

Accordingly, as shown in (a) of FIG. 9, when the freezer compartment door is opened, the rotary link 262 moves relatively quickly by the large restoring force of the tension spring 266 to move the rotary cover 271 of the ice maker cover 270. Will be closed. Here, the connection spring 267 is to simply push the function.

On the contrary, when closing the freezer compartment door as shown in FIG. 9B, the rotary link 262 opens and rotates the rotary cover 272 of the ice maker cover 270 according to the tension of the tension spring 266. At this time, the connection spring 267 between the long connecting rods 263 and the short connecting rods 264 of the rotary link 262 acts as a buffer, so that the open rotation speed is operated slowly.

In addition, since the central shaft 265 has a structure in which the long connecting rods 263 and the short connecting rods 264 are separated from each other, the central shaft 265 performs a hinge function at the central portion. In this case, the hinge performs a soft rotation in the direction of opening the door and a stiff rotation in the direction of closing the door.

The rotation control means of the ice maker cover may be configured using a link, a spring, or the like as described above, or alternatively, may be implemented by an electromagnetic moving means.

10 is a configuration provided with an electromagnetic movement means as another embodiment of the present invention.

Referring to FIG. 10, a switch SW1 for electrically sensing the upper part of a freezer compartment door and power is supplied / blocked according to a detection result of the switch SW1, and vertical up / down movement is performed as power is supplied / blocked. A solenoid 361, a rotary link 362 that rotates according to the solenoid, and an ice maker cover 370 that opens and closes the ice maker by the rotary link 362.

The solenoid 361 includes the coils 361a on both sides, the cylinder 361b, the core 361c on the lower side of the cylinder, the elastic spring 361d, and the plunger 361e vertically moving up and down inside the cylinder, as shown in FIG. It consists of. The solenoid 361 may rotate the rotary link 362 by vertically moving the plunger 361e according to the power supply of the coil 361a.

Specifically, referring to FIGS. 10A and 11, when the freezer compartment door 303 is opened, the switch SW1 is turned off to cut off power to the coil 361a of the solenoid 361. At this time, the solenoid 361 rotates the rotary link 362 by moving the plunger 361e upward in the cylinder 261b by the force of the spring 361d. Accordingly, the rotation shaft 273 of the ice maker cover 270 connected to the end of the rotary link 262 rotates, and the rotary cover rotates in the direction of closing the ice maker.

On the contrary, referring to FIGS. 10B and 11, when the freezer compartment door 303 is closed, the switch SW1 is turned on so that the coil 361a of the solenoid 361 is supplied with power to form a uniform magnetic field. At this time, the solenoid 361 rotates the rotary link 362 by moving the plunger 361e downward in the cylinder 261b while the coil magnetic field force overcomes the force of the spring 361d. Accordingly, the rotation shaft 273 of the ice maker cover 270 connected to the end of the rotary link 262 rotates and the rotary cover rotates in the direction of opening the ice maker.

As another embodiment, the operation may be configured in the opposite operation to the above description according to the installation direction of the solenoid as shown in FIG. 11. Alternatively, it may be configured hydraulically.

So far, the present invention has been described with reference to its preferred embodiments, but one of ordinary skill in the art to which the present invention pertains may implement another embodiment of a modified form within the essential scope of the present invention. .
