Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an icemaker and a refrigerator including the icemaker,

The present invention relates to an ice maker and a refrigerator including the same.

Generally, a refrigerator has a refrigerating chamber for refrigerating and storing food and a freezing chamber for refrigerating and storing food. At this time, an ice maker for producing ice is installed in the freezing room or the refrigerating room. The ice-making system of the ice maker is divided into an indirect cooling type in which ice is produced by cooling the tray by forced convection by supplying cold air in the refrigerator by an ice maker, and a direct cooling type in which ice is produced by bringing the refrigerant tube into direct contact with a tray . Direct cooling has the advantage that the deicing mechanism is relatively simple and the cooling rate is very fast. In the conventional direct-cooled ice-maker, a U-shaped sheath heater is mainly used as a heater that serves to allow freezing of ice in the ice tray. The filling thickness of the insulating powder is thicker than that of the heat line, and the heat transfer distance generated from the heat line is distant. Therefore, in order to transfer heat to the outside of the sheath heater, the heat of the heat must be high, and a lot of energy is consumed in order to generate a high temperature in the heat. In addition, since the sheath heater is formed in line contact with the ice tray in a U-shape, the area of contact with the ice tray is so small that the heat transfer efficiency is poor. In order to transfer heat to the portion not in direct contact with the heater, And power is consumed. At this time, since the ice tray is excessively heated by the heater, it takes a lot of time to cool the ice tray again to the ice making temperature in the ice making cycle after the ice making, thereby lengthening the ice making time. In addition, since the conventional heater has a metal support formed by die casting in the lower part thereof, it is difficult to control the heater temperature for melting or re-cooling the ice already melted by the metal support heated from the heater. Further, since it is necessary to raise the temperature of the heater to a very high level, the material constituting the ice tray in contact with the heater is limited to a material such as metal that can withstand high temperatures. In addition, there are many problems in the vicinity of the ice tray and the refrigerant pipe, and in the course of the ice making process, there is a reliability problem such that ice is generated due to melting of the ice, and the ice making performance may be deteriorated.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is merely an example and the present invention is not limited thereto.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

1 is a perspective view of an ice maker 3 according to an embodiment of the present invention.

The icemaker 3 in one embodiment of the present invention may include an icestrel 310, a control box 320, a freezing heater 200, and a drain member (100 in FIG. 2). 1, an icestroy 310 in which an ice heater (20 in FIG. 3) and a drain member (100 in FIG. 2) are positioned below, and a control box 320 connected to one side of the ice storer 310, . ≪ / RTI > On the other hand, the icemaker 3 functions by being released after the fluid supplied from the water supply device (not shown) to the receiving portion (312 of FIG. 4) becomes the ice 1. The ice can be released and moved by the rotation of the ejector pin 311, which can be rotated or pivoted by the control box 320. The moved ice 1 can be received inside the storage part 2 located below the ice storer 310. By repeating this process, ice (1) can be continuously generated.

In order for the ejector pin 311 rotated by the control box 320 to move the ice 1, the receiving portion 312 of the ice storer 310 and the ice 1 may be separated from each other have. 3) is placed in contact with the lower surface of the ice storer 310 so as to separate the ice 1 from the accommodating portion (312 in FIG. 4), so that the rotation of the ejector pin 311 It can be exothermic before.

3) can be periodically generated, and the heat released from the freezing heater (20 in FIG. 3) is transmitted to the ice storer 310 side, (312 in Fig. 4), the ice adhered to the surface due to cooling can be separated from the side surface of the receiving portion (312 in Fig. 4). Here, the heat may be transmitted downward from the icestray 310.

The heat transferred to the downward direction can expose the ice 1 stored in the storage unit 2 to the temperature of the image, so that the ice 1 can be melted. 3) between the storage part 2 and the heater (20 in FIG. 3) so as not to be transmitted to the storage part 2 side, The drain member (100 in Fig. 2) can be positioned. Specifically, the drain member (100 in Fig. 2) can be placed between the heater (200 in Fig. 2) and the ice (1) stored in the storage unit (2).

On the other hand, the ice maker 3, which is an embodiment of the present invention, can perform ice-making by direct cooling or indirect cooling. The case of ice-making by direct cooling is an example of Fig. 2, and the case of ice-cooling by ice-cooling is an example of Fig. First, referring to Fig. 2 showing the case of direct cooling, and with regard to coupling of the drain member (400 in Fig. 3) and the anti-freezing heater 200, will be described later with reference to Fig.

2 is an exploded perspective view of a part of the direct-cooled ice maker according to the embodiment of the present invention.

Referring to FIG. 2, the icemaker for performing ice-making by direct cooling may include an icestrel 310, a control box 320, an anti-icing heater 200, a drain member 100, and a cooling pipe 10. Here, the ice-making heater 20 and the cooling tube 10 located on the lower surface of the ice stray 310 can be heated and absorbed (cooled) respectively by the receiving portion 312 provided in the ice tray 310, have.

Here, a part of the fluid may be blown out of the receiving part 312 when the receiving part 312 of the icestray 310 exceeds the acceptable capacity or the fluid is supplied by the water supplying part (not shown). When the temperature difference due to the cooling by the cooling tube 10 and the heat generated by the freezing heater 20 occurs, moisture may be formed on the surfaces of the ice storey 310 and the drain member 100. However, The water can be collected and the fluid can fall into the drain member 100.

The fluid dropped into the drain member 100 can be drained, and the drained fluid can flow in the guiding direction of the drain member 100. That is, the drain member 100 may be positioned so that the fluid falling downwardly flows into the drain member 100 without flowing into the storage unit 2 or the like. When the cooling pipe 10 is driven for ice-making while the fluid dropped to the drain member 100 is dropped into the drain member 100, the fluid may freeze.

The drain of the drain member 100 drained by the fluid that can not be accommodated in the accommodating portion 312 may be clogged if the fluid is frozen inside the drain member 100 repeatedly. If the excess fluid can not be drained from the drain member 100 due to such clogging, the fluid may flow into the storage unit 2 and the like, and the generated ice 1 may be frozen and fixed to each other. Therefore, in order to prevent this, the anti-freeze heater 200 may be heated to a predetermined temperature for a predetermined time so that the fluid in the drain member 100 does not freeze in the drain. For example, the anti-icing heater 200 may be heated to 20 degrees. On the other hand, a conventional heater, for example, an aluminum pipe heater, can raise the temperature by about 100 ° C. in heating. When the metal bearing which conveys the elevated temperature is placed in contact with it, The efficiency of ice-making and ice-making can be reduced.

The heat emitted from the heater 200 positioned on the lower surface of the ice storay 310 can be prevented from reaching the storage unit 2 so that the ice 1 produced in the storage unit 2 is not melted. The drain member 100 may be raised to a predetermined temperature in the blocking process. The drain member 100 may be formed of a material having a low thermal conductivity so that the ice 1 stored in the storage unit 2 is not affected as much as possible by the predetermined temperature rise. For example, a plastic material and the like. When the drain member 100 is formed of a metal material manufactured by die casting, the heat released as the temperature of the heater 200 is increased is easily transmitted to the storage portion 2, and even after the heat generation of the heater 200 is stopped, The drain member 100 of the ice maker 1 has latent heat, so that the ice 1 generated by the latent heat can be affected and melted. Accordingly, the drain member 100 can be formed of a material having a low thermal conductivity.

On the other hand, the drain member 100 may be positioned to face the heater 200 in order to discharge the fluid dropped onto the drain member 100, and may be positioned to be inclined with respect to the horizontal direction. When the fluid flows down to the low position by the inclination, the fluid can be moved to the discharge position along the drain.

In this embodiment, which is a direct-cooled ice-maker, the heater 200 and the cooling pipe 10 can be operated alternately. For example, the heater 200 is operated at the time of water supply and at the time of ice removal, and the cooling pipe 10 can be operated at the time of ice-making. The heater 200 can be selectively operated, and the operation of the heater 200 can be controlled by the control box. In the case of the heat generation order, the control may include heating after the rotation of the ejector pin 311, which is controlled by the control box, at the time of water supply, or after a predetermined cooling time has elapsed, For example, to generate heat for heating.

FIG. 3 (a) is a side sectional view of an ice maker according to another embodiment of the present invention, and FIG. 3 (b) is a perspective view and a partial enlarged view of a drain member 400 according to another embodiment of the present invention.

3 (a) and 3 (b), the icemaker may include an icemaker 410, a drain member 400, and a heater 200. Of course, the cooling tube 10 for cooling and the freezing heater 20 for freezing can also be included, but various forms of the freezing heater 20 and cooling methods including direct cooling and indirect cooling can be modified by those skilled in the art, It is not specified.

The drain member 400 and the anti-icing heater 200 may be insert-coupled. A heater may be positioned on the upper surface of the drain member as in the embodiment described above with reference to FIG. In this embodiment, when the drain member 400 is manufactured through injection or the like, the icemak prevention heater 200 can be manufactured by being inserted. The anti-icing heater 200 may be inserted into the drain member 400 to generate heat at a predetermined temperature. For example, it is possible to prevent the fluid that comes into contact with the drain member 400 from being frozen while generating heat at 20 degrees. The fluid may be a part of the fluid supplied from the water supply part and may be cooled on the surface of the drain member 400 and the ice straw 410 due to the condensation phenomenon caused by the temperature difference in the process of being cooled for ice- Lt; / RTI > fluid.

The fluid formed by the condensation shape can be continuously generated due to the temperature difference, and can be dropped in the fluid drop direction D, that is, downward, when the amount of the fish fluid is increased. The fluid that has fallen downward can be positioned on the drain member 400 and can be moved to a low position by the inclination formed on the drain member. However, it may not move in the drain member in which no warp is formed. In the inclined drain member 400, it can be moved to a low position and discharged by the drain. Since this process is repeated, the ice-making can be smoothly performed.

However, if the fluid drops below the freezing point in the process of dropping onto the drain member 400 and moving to a lower position by tilting, the state of the fluid may be changed to ice. It is more likely to occur in a cold-cooled ice-maker, which is constantly exposed to sub-zero temperatures rather than direct cooling. Therefore, if the fluid dropped by the environment of the exposed subzero temperature is repeatedly frozen on the drain member 400, the fluid can not be discharged and the ice making and removing efficiency can be reduced. Therefore, a heater such as a film heater including a film, a flat heater, a code heater, and a print heater can be combined with the drain member 400. The bond means an insert or a bond by contact or the like.

For example, if the freezing prevention heater 200 generates heat in a normal temperature range (for example, 20 degrees) and maintains the heat generation for a predetermined time, the fluid above the drain member 400 can avoid freezing. The predetermined time may be a time for which the temperature of the image is kept constant while the fluid is discharged through the drain.

Prevention of freezing

4 is an exploded perspective view of a part of the ice-cooled ice-maker according to another embodiment of the present invention.

Referring to FIG. 4, the icemaker for performing ice-making by ice-cooling may include an icestra 310a, a control box 320a, a heater 200a, and a drain member 100a. Here, the ice-maker can heat the receiving portion 312a side by the ice-making heater 20 located on the lower surface of the ice storey 310a to thereby freeze the ice. Since the heat transfer is performed in all directions from the ice heater (20) as well as the ice stora (310a) side during the above-described freezing process, the heat transfer may affect the configuration located nearby.

For example, when the ice 1 is melted to form a fluid between ice and neighboring ice during heating of the ice heater 20, when the ice is frozen in the freezing environment in which the ice maker is exposed, Each of the ice can be frozen and fixed to each other by cooling. The ice fixed to each other can provide a discomfort to the user when supplied.

In addition, when the accommodating portion 312a of the eye strainer 310a exceeds the accommodating capacity or a fluid is supplied by the water supplying portion (not shown), a part of the fluid may be blown out of the accommodating portion 312a. Particularly, when a temperature difference occurs due to cooling by the cooling tube 10 and heat generation of the freezing heater 20, moisture may be formed on the surface of the ice storey 310a and the drain member 100a. When the amount of water is continuously increased, the water may be collected and the fluid may fall into the drain member 100a.

The fluid can be dropped and discharged to the drain member 100a, and the discharged fluid can flow in the guiding direction of the drain member 100a. That is, the drain member 100a may be positioned so that the fluid falling downwardly flows into the drain member 100a without being introduced into the storage unit 2 or the like. The fluid dropped to the drain member 100a may be exposed to the sub-zero environment in a state where the fluid falls into the drain member 100a.

If the case where the fluid is frozen inside the drain member 100a is repeatedly performed, the drain or the like of the drain member 100a drained by the fluid that can not be accommodated in the accommodation portion 312a may be clogged. If the drain member 100a can not drain the excess fluid due to the clogging, the fluid can flow into the storage unit 2 or the like, and the generated ice 1 can be frozen and fixed to each other. Therefore, in order to prevent this, the heater 200a may generate heat for a predetermined time at a predetermined temperature so that the fluid does not freeze in the drain in the drain member 100a. For example, the heater can be heated to 20 degrees. On the other hand, a conventional heater, for example, an aluminum pipe heater, can raise the temperature by about 100 ° C. in heating. When the metal bearing which conveys the elevated temperature is placed in contact with it, The efficiency of ice-making and ice-making can be reduced.

In order to prevent the ice 1 generated in the storage unit 2 from dissolving, the heat emitted from the heater 200a located on the lower side of the ice stora 310a may be prevented from reaching the storage unit 2 side . The drain member 100a may be raised to a predetermined temperature in the blocking process. The drain member 100a may be formed of a material having a low thermal conductivity such that the ice 1 stored in the storage unit 2 is not affected as much as possible by the predetermined temperature rise. For example, the drain member 100a may be formed of a material including a plastic material or glass. When the drain member 100a is formed of a metal material manufactured by die casting, the heat released as the temperature of the heater 200a is increased is likely to be transmitted to the storage part 2 side, and even after the heat generation of the heater 200a is stopped, Since the drain member 100a of the ice maker 100 is subject to latent heat, the ice 1 generated by the latent heat may be affected and melt. Accordingly, the drain member 100 can be formed of a material having a low thermal conductivity.

On the other hand, the drain member 100 may be positioned to face the heater 200 in order to discharge the fluid dropped onto the drain member 100, and may be positioned to be inclined with respect to the horizontal direction. The fluid can be moved to the discharge position along the drain when the fluid flows down to the low position by the slope.

Further, in the case of the ice-cooled ice-maker, since the environment in which the ice maker is disposed is at a sub-zero temperature, it can be exposed to a continuous sub-zero temperature. Accordingly, the heater 200a can be selectively operated, and the operation of the heater 200a can be controlled by the control box. In the case of the heat generation order, the control may include heating after the rotation of the ejector pin 311, which is controlled by the control box, at the time of water supply, or after a predetermined cooling time has elapsed, For example, to generate heat for heating.

The supporting portions 110 and 110a of the drain members 100 and 100a included in the ice maker shown in FIGS. 2 and 4 are formed to extend from the drain members 100 and 100a toward the heaters 200 and 200a, The support members 200 and 200a may be closely attached to the support and the eye strains 310 and 310a by the support portions 110 and 110a. Further, since the spaced distances are determined according to the extended lengths of the supports 110 and 110a, the longer the length is, the lower the amount of heat transfer downward, and the smaller the contact area with the heaters 200 and 200a , It is possible to expect an effect that the amount of heat transferred through conduction can be reduced while supporting the semiconductor device through the contact.

5 is a side sectional view of the icemaker 3 according to an embodiment of the present invention.

Referring to Figure 5, a direct cooled ice maker is shown. Hereinafter, a direct-cooled ice-maker will be described as an example. An ice maker 3 according to an embodiment of the present invention includes an ice stray 310, a freezing prevention heater 200, a cooling pipe 10, a freezing heater 20 and a drain member 100, The storage unit 2 can be positioned below the storage unit 2. The ice maker 3 is supplied with a fluid from a water supply unit (not shown), and the fluid can be received in a receiving unit 312 provided in the icestray 310. The fluid contained in the accommodating portion 312 can be frozen by the operation of the cooling pipe 10. The ice 1 generated here can be separated from the ice storer 310 and moved to the storage part 2. [

The ice-making heater 20 located on the lower side of the ice storey 310 may be heated, and at this time, the operation of the cooling tube 10 may be stopped. That is, the heater 200 and the cooling pipe 10 can alternatively be operated alternately. The ice 1 separated from the ice storey 310 by the operation of the ice-making heater 20 can be released by the ejector pin 311 rotated by the control box. The ice cubes 1 are separated from the ice storey 310 and can be moved into the storage section 2 by self weight or external force. In the case of this embodiment, the storage unit 2 is located below and the ice 1 can be dropped and moved to the storage unit 2 by the weight of the ice 1.

After the ice 1 is detached, the water supplied to the accommodating portion 312 is supplied to the water receiving portion (not shown), and the ice making process can be repeatedly performed. The ice-making heater 20 and the cooling pipe 10 can be repeatedly operated while the repeated ice-making process is performed, which can affect the drain member 100 by the operation. Particularly, when the ice-making heater 20 is in operation, moisture is generated due to the difference between the temperature at which the increased temperature emitted from the ice-making heater 20 is cooled by the cooling tube 10 at the time of cooling, The freezing prevention heater 200 can be heated (for example, 20 degrees) to the temperature of the image so as to prevent the fluid from freezing on the drain member 100 so as to be drained by the drain.

That is, the heat transfer direction may be blocked downward and the heat may be transmitted to the upper side of the eye strainer 310. Specifically, the drain member 100 is located in the fluid drop direction D below the freeze-prevention heater 200, so that the ice 1 contained in the storage unit 2 is heated by the heat generated by the freezing heater 20 So that it can be prevented from being dissolved. Further, the drain member 100 may be formed of a heat-resistant material. For example, a material including plastic or the like.

6 is an exploded perspective view of a heater 200 according to another embodiment of the present invention.

Referring to FIG. 6, the anti-icing heater 200 according to an embodiment of the present invention may include a first film 220, a second film 230, and a heat line 210. Here, the hot wire 210 may be disposed between the first film 220 and the second film 230 and may be sandwiched between the films 220 and 230 on both sides thereof. The films 220 and 230 may be an insulator and may be a material capable of dissipating the heat of the heat rays 210 through the surfaces of the films 220 and 230. For example, the films 220 and 230 may be polyimide (PI).

That is, the temperature control can be facilitated while the films 220 and 230 function as an insulator. On the other hand, in the case of an aluminum pipe heater, the aluminum surface may be increased by, for example, about 100 degrees, and once it is heated, it may be difficult to cool the aluminum pipe heater because latent heat is left for a long time during the cooling again. Accordingly, the anti-icing heater 200 including the films 220 and 230 which are heated up to the required temperature and which are not dissipated by the surrounding environment and have latent heat, may be more preferable for temperature control. In addition, the anti-freeze heater 200 may be less expensive than a planar heater including an aluminum pipe heater and a metal body.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
