In general, a home refrigerator is a device for keeping food and the like at a low temperature by having a predetermined accommodation space, and is divided into a refrigerating chamber which maintains an image by dividing the low temperature range and a freezing chamber which is kept below zero. Recently, as the demand for ice increases, refrigerators equipped with automatic ice makers capable of making ice are increasing.

The automatic ice making device (hereinafter, referred to as ice making device) may be installed in the freezer compartment according to the aspect of the refrigerator, and in some cases, may be installed in the refrigerator compartment. When the ice maker is installed in the refrigerating chamber, the ice cold is guided to the ice maker to perform ice making.

In addition, to achieve the object of the present invention, the step of making ice in the ice maker; Receiving an ice extraction signal from a user; Rotating the ice tray of the ice maker; Separating ice from the ice maker; And a step of taking out the separated ice is provided.

The icemaker and the refrigerator having the same according to the present invention provide a method of supplying the ice by reducing the size of the ice maker as the ice maker rotates to freeze the ice, thereby reducing the size of the ice maker. The refrigerator provided with an ice making apparatus can be made slim.

In addition, since no separate partition is provided on the inner circumferential surface of the ice making container, the inner circumferential surface roughness of the ice making container can be increased, and when the ice making heater is installed in the ice making container, heat transfer by the ice making heater is evenly transmitted. Reducing the amount of residual water that can be effectively carried out prevents the stored ice from tangling.

In addition, the ice making container is rotated to push the ice to freeze the ice falling freely so that the ice can be carried out without using the heater for defrosting to reduce the power consumption and the residual water that can be generated when using the heater Can be further reduced.

In addition, the container portion 121 is protruded in the form of teeth at one end of the opening is formed with a pusher (123) for pushing the ice in each unit space (C). In addition, a fluorine coating surface may be formed on an inner circumferential surface of the ice making container 120 forming the ice making space 122. Of course, the coating surface may be formed of other materials such as fluorine as well as ceramics.

The shaft part 125 may be formed at an approximately axial center of the container part 121 and may be coupled to the driving part 140 with the speed reducer interposed therebetween.

The partition plate 130 extends in the same direction as the shaft portion 125 of the ice making container 120 and is formed in a shaft shape and is fixed to the driving unit 140 and the fixing portion 131. A plurality of partitions 132 formed at predetermined intervals along the axial direction in the direction of the ice-making vessel and partitioning the ice-making space 122 into a plurality of unit spaces C, and upper surfaces of the partitions 132. The stopper portion 133 is connected to each other so that the ice in the unit space (C) can be iced without rotating together along the ice making container 120 when the ice making container 120 rotates.

As described above, one end of the fixing part 131 is integrally coupled to and fixed to the motor housing 141 constituting the driving part 140, while the other end is centered on the container part 121 of the ice making container 120. Rotatably coupled to.

The partition 132 is formed in the same shape as the ice making space 122, that is, semi-circular shape in the axial projection. In addition, the partition 132 may be formed to allow the outer circumferential surface of the partition wall 132 to be in contact with the inner circumferential surface of the ice making space 122 to reduce the connection area between the pieces of ice and to make the ice.

In addition, a water channel 135 having a predetermined depth is formed at one side of the outer circumferential surface of the partition wall part 132, more precisely, at the lowest point of the partition wall part 132 so that water moves to the unit space C. do. Of course, the channel 135 may be formed in the middle of the partition 132.

The stopper part 133 is preferably formed at the tip side of the side in which the pusher 123 of the ice making container 120 is provided, that is, when the ice making container 120 rotates as shown in FIG. 3. The stopper part 133 may be formed to cover the entire upper surface of one side of the partition parts 132, but in some cases, the stopper part 133 may be formed to protrude so that the ice does not return together with the ice making container 120. However, since the stopper 133 may also serve to prevent the water contained in the ice making container 120 from splashing, it may be more preferably formed as wide as possible.

The surface of the partition plate 130 may be further formed with a fluorine-based coating surface, such as the inner peripheral surface of the ice making container 120.

The driving unit 140 includes a motor housing 141 fixed to the ice making chamber 51, a driving motor 142 installed inside the motor housing 141 to generate a rotational force, and the driving motor 142. It may be made of a reduction gear 143 coupled to the deceleration to transmit the rotational force to the ice-making container 120.

The shaft portion 125 of the ice making container 120 is rotatably coupled to the motor housing 141 while the fixing portion 131 of the partition plate 130 is fixedly coupled to the motor housing 141.

On the other hand, the ice making container 120 is formed of a thermally conductive material such as aluminum to separate the ice from the ice making space 122 of the ice making container 120, the ice on the outer circumferential surface of the ice making container 120 Ice heater 150 may be installed. The heater 150 may be formed of a hot wire heater in contact with the outer circumferential surface of the ice making container 120.

In addition, the heater 150 may be controlled to interlock with the water supply unit 110. For example, whether water is supplied to the ice making container 120 for ice making or ice making according to a change in a value detected by a water level sensor or a flow sensor of the water supply unit 110, Alternatively, it is determined whether or not the ice is being processed after ice making is completed, and if it is determined that the water is supplied for ice making or it is determined that water is completed to perform ice making, the operation of the heater 150 is stopped. On the other hand, when the ice making is determined to be a process in which the ice is completed, it may be controlled to start the operation of the heater 150.

Here, the time point at which the heater 150 is operated may be determined by sensing the temperature of the ice making container 120 in real time or periodically, or after the value of the water level sensor or the flow sensor of the water supply unit 110 is changed. Data may be passed over time to force operation according to the data value. That is, the completion of the ice making operation can be confirmed through the temperature detection of the ice making container 120 or through the ice making time. For example, when the temperature measured by a temperature sensor (not shown) mounted on the ice making container 120 is below a predetermined temperature, for example, about −9 ° C. or less, it is determined that ice making is completed or predetermined after water supply. When the time elapses, it is possible to determine whether ice making is completed by determining that ice making is completed.

Although not shown in the drawing, the heater 150 may include a conductive polymer, a plate heater with positive thermal coefficient, an aluminum thin film, and other heat transfer in addition to the heat heater. Possible materials and the like.

The heater 150 may be attached to the front surface of the ice making container 120, but may be embedded in the ice making container 120 or may be provided on an inner circumferential surface of the ice making container 120. It may be. Furthermore, the heater 150 may be implemented by forming the ice maker as a heat generating resistor so that at least a portion of the ice maker 120 generates heat when electricity is applied without using a separate heater.

In addition, the heater 150 may be installed to be spaced apart from the ice making container 120 by a predetermined interval without contacting the ice making container 120 to constitute a heat source. Examples of other heat sources include a light source for irradiating light to at least one of the ice and the ice maker 120, and a magnetron for irradiating microwaves to at least one of the ice and the ice maker 120. As described above, a heat source such as a heater, a light source, or a magnetron applies heat energy directly to at least one of the ice and the ice making container 120 or a boundary thereof to melt a portion of an interface between the ice and the ice making container 120. give. Accordingly, when the ice container 120 is rotated, the ice may be iced by its own weight or by the pusher 123 of the ice container 120 even though the interface with the ice container 120 is not thawed. To be separated from the vessel 120.

Meanwhile, the heater 150 and the driving motor 142 may be controlled together by one control unit 160, that is, a microcomputer, electrically connected to the heater 150 and the driving motor 142. For example, as shown in FIG. 5, the control unit 160 is connected to a temperature sensor (not shown) to detect the temperature of the ice making container 120 or a timer (not shown) to detect an elapsed time after water supply. A detection unit 161 connected to the control unit, a determination unit 162 determining whether ice making is completed by comparing the temperature or time detected by the detection unit 161 with a reference value, and according to the determination of the determination unit 162. Commander 163 for controlling the on / off of the heater 150 and the operation of the drive motor 142.

The ice supply method in the refrigerator according to the present invention as described above is as shown in Figs.

As shown in FIG. 2, when ice making is required, the ice making apparatus 100 is turned on and the ice making operation is started (S1). When the ice making operation is started, the water supply unit 110 supplies water to the ice making container 120 (S2). At this time, the water supply amount is detected in real time using a water level sensor installed in the ice making container 120 or a flow rate sensor installed in the water supply pipe or a water level sensor installed in the water tank, and the detected water supply amount is transferred to the microcomputer. The received microcomputer is compared with the set water supply amount (S3). By the comparison, it is determined whether an appropriate amount of water is supplied to the ice making container 120, and when it is determined that an appropriate amount of water is supplied to the ice making container 120, the water supply valve of the water supply unit 110 is shut off to further water. Do not supply to the ice tray 120 (S4).

Next, when the supply of water to the ice-making vessel 120 is completed, the water in the ice-making vessel 120 is exposed to the cold air supplied to the ice-making chamber 51 for a predetermined time or more and frozen (S5). While the water of the ice making container 120 is iced, the temperature sensor (not shown) detects the temperature of the ice making container 120 periodically or in real time and delivers it to the microcomputer. Compare with the set temperature (S6). By this comparison, it is determined whether the surface of the water contained in the ice making container 110 is frozen, and if it is determined that the ice is frozen, the series of operations are stopped and the process is switched to the ice making step (S7).

Next, when the ice is required by the user, the heater 150 is operated by the control unit 150, and when the heater 150 is operated, heat is applied to the ice making container 120 while the ice making container ( The outer surface of the ice I in contact with the inner circumferential surface of 120 starts to melt (S8 ~ S9).

Next, when the driving motor 142 is operated by the control unit 150 to rotate the container portion 121 of the ice making container 120 about the shaft portion 125, the unit space (C) Ice (I) is caught on the stopper portion 133 of the partition plate 130 to prevent rotation along the ice making container (120). (S10) Then the ice making container 120 further rotates the ice making The pusher 123 of the container 120 passes between the partition portions 132 formed on the opposite side of the stopper portion 133 of the partition plate 130 to drive the ice F in each unit space C. It is pushed out by the rotational force F by the motor 142. Then, the ice I adhering to the partition plate 130 is separated from the partition 132 and the stopper part 133 of the partition plate 130 and is freely dropped and discharged into the ice storage container 52 or directly dispenser. It is discharged toward 53. (S11-S12)

Here, stopping the supply of cold air supplied to the ice making chamber 51 in the process of ice or ice preparation in the ice making container 120 may facilitate the ice making operation and the heater 151. It is preferable to reduce the power input to the).

Next, when the extraction is completed, the operation of the heater 150 is stopped and the water supply valve 112 is opened, and a series of processes of supplying the appropriate amount of water to the ice making container 120 again by the water level sensor and the flow sensor are repeated. Done.

As the ice making container rotates, ice is freely dropped while the ice making container rotates, thereby reducing the size of the ice making device and reducing the area occupied by the ice making device, thereby making the refrigerator or refrigerator door slimmer. That is, conventionally, as the ejector lifts and ices the ice of the ice making container, not only the space for spreading the ice in the ice making container is required, but also the ice storage container is stored in front of the ice making container to store the ice. Since the total area occupied by the ice making device has to be widened, and thus, the refrigerator has a limitation in slimming the refrigerator, in the present invention, since the ice making container rotates, the ice does not need to be spun up by rotating the ice to freeze the ice. Since the ice ice space is reduced and the ice storage container is provided on the lower side of the ice making container, the area occupied by the ice making device is significantly reduced, thereby making the refrigerator or the refrigerator door slim.

In addition, since no separate partition is provided on the inner circumferential surface of the ice making container, the inner circumferential surface roughness of the ice making container can be increased, and when the ice making heater is installed in the ice making container, heat transfer by the ice making heater is evenly transmitted. Reducing the amount of residual water that can be effectively carried out prevents the stored ice from tangling.

In addition, the ice making container rotates to push the ice to allow the ice to freeze while freezing, thereby eliminating the use of the ice heater, and in this case, it is possible to proceed the ice ice operation without using the heater. The quality of the ice stored in the ice storage container can be improved by lowering and reducing the residual water that can be generated when using the heater.

Meanwhile, when the ice maker 100 is installed in the refrigerator door, as shown in FIGS. 8 and 9, when the refrigerator door is opened and closed, the water filled in the ice maker 120 may shake before being completely iced. The cover plate 170 may be further provided at an upper side of the partition plate 130 to prevent the water contained in the ice making container 120 from overflowing.

The cover plate 170 is formed in a semi-circular cross-sectional shape convex in the opposite direction to the ice making container 120, the water supply port 171 can be formed wide in the horizontal direction in the center of the top of the cover plate 170. In addition, the cover plate 170 may be provided with an elastic portion 172 so that the cover plate 170 may be elastically opened when the ice making container 120 rotates. Reference numeral 173 in the figure indicates a cold air hole.

When the cover plate is provided as described above, even when the ice making device is installed in the refrigerator door, the water contained in the ice making container can be prevented from shaking and the ice making effect can be enhanced. Even in this case, since the configuration and operation of the ice making apparatus are the same as in the above-described embodiment, a detailed description thereof will be omitted.

On the other hand, the refrigerator according to the present invention and the ice making method of the refrigerator can be applied to all the refrigerators having a refrigerator ice maker having a double door open door.
