Description

TECHNICAL FIELD [0001] The present invention relates to an evaporator for ice making,

The present invention relates to an evaporator for ice making, which is provided in an icemaker and which generates ice by heat exchange with water by flow of cold refrigerant. More particularly, the present invention relates to an evaporator for evaporating refrigerant, And an ice maker for evaporating ice generated in association with the evaporator, wherein the evaporator is integrally formed with a heating part for ice making.

The evaporator for ice making is provided in an ice maker for making ice. The evaporator for ice-making 10 includes an evaporator 20 as shown in FIG. The evaporator 20 is included in the refrigeration cycle. As a result, cold refrigerant flows to the evaporator 20.

In the case of the submerged ice making machine, one or more immersion members 40 are connected to the evaporator 20 as shown in FIG. Therefore, the coolant also flows into the immersion member 40. [ The immersion member 40 is supplied to a tray member (not shown) positioned under the immersion member 40 and immersed in the immersed water.

With this configuration, the immersion member 40 is transferred from the submerged water to the coolant refrigerant flowing in the evaporation unit 20, so that ice (not shown) may be generated in the immersion member 40.

7, the ice generated in the immersion member 40 is supplied to the evaporator 20 of the evaporator 10 for ice-making so that the hot refrigerant flows to the evaporator 20, The heating section 30 including the heating section 30 is separated from the immersion member 40 by heating the evaporation section 20 to be de-iced.

7, the heating unit 30 of the conventional evaporator 10 is connected to the evaporator 20 by a bracket B. As shown in FIG. That is, there is a problem that the evaporator 20 and the heating unit 30 are not integrally formed. Accordingly, there is a problem that the evaporator 20 and the heating unit 30 are not completely in contact with each other but are in line contact with each other.

When the evaporator 20 and the heating unit 30 are in contact with each other without making contact with each other in this way, the heat of the heating unit 30 is generated in association with the evaporator 20 through the evaporator 20 In the case of ice and immersion ice-maker, there is a problem that it can not be properly transferred to ice produced in the immersion member 40. Accordingly, if the heating temperature of the heating unit 30 is relatively high, for example, the temperature of the heating unit 30 should be in the range of 80 to 90 deg.

Thereby, there is a problem that the heating unit 30 can overheat more than necessary, thereby increasing the heat loss. Further, there is a problem that a safety accident occurs, for example, the user wears an image by the high-temperature heating unit 30.

Further, in the related art, in order to transfer heat from the heating section 30 to the evaporation section 20, cold refrigerant is prevented from flowing to the evaporation section 20 at the time of ice excavation. For this purpose, the driving of the compressor (not shown) included in the refrigeration cycle is stopped at the time of defrosting the ice, and the compressor is driven again after the defrosting of the ice is completed.

In other words, for ice riding, the compressor had to be stopped and driven repeatedly.

When the compressor is initially driven or reconfigured, energy required for the compressor, for example, current is high, resulting in high energy consumption. Therefore, there is a problem in that energy is consumed more by repeating the stopping and driving of the compressor, and therefore energy efficiency is lower than when the compressor is continuously driven.

In addition, there is a problem that a waiting time of 3 minutes to 5 minutes is required due to the locking phenomenon at the time of re-starting the compressor. That is, there is a problem that the compressor is driven in a normal state only after 3 minutes to 5 minutes after the compressor is restarted.

Further, since the temperature of the refrigerant rises when the driving of the compressor is stopped, there is a problem that the icemaking can not be performed immediately even if the compressor is driven again. That is, there is a problem that a waiting time is required for the temperature of the refrigerant to drop to the temperature for ice-making.

Therefore, there is a problem that the entire ice making time becomes long and the ice making cycle becomes longer, and the ice making amount of the ice making machine becomes relatively small.

The present invention is realized by recognizing at least any one of the requirements or problems occurring in the conventional evaporator for ice making.

One aspect of the object of the present invention is to increase the ice making amount of the ice maker provided with the evaporator for ice making.

Another aspect of the object of the present invention is to reduce the ice-making time.

Another aspect of the object of the present invention is to ensure that the heat is properly transferred from the heating part including the heater during ice decking to ice.

Yet another object of the present invention is to allow deicing of ice even if the heating temperature of the heating part is relatively low.

Another aspect of the object of the present invention is to prevent a safety accident such as a user's image due to overheating of the heating unit.

Another object of the present invention is to enable deicing of ice even in the state where cold refrigerant flows.

Hereinafter, exemplary embodiments will be described based on embodiments best suited for understanding the technical characteristics of the present invention, and the technical features of the present invention are not limited by the illustrated embodiments, It is to be understood that the present invention may be implemented as illustrated embodiments. Therefore, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. In order to facilitate understanding of the embodiments to be described below, in the reference numerals shown in the accompanying drawings, the related elements among the elements that perform the same function in the embodiments are indicated by the same or an extension line number.

Embodiments related to the present invention are basically based on the fact that the evaporation portion included in the refrigeration cycle in which the refrigerant flows and the heating portion for heating the evaporation portion are integrally formed.

1 to 5, the evaporator 100 for ice making according to the present invention may include an evaporator 200 and a heater 300.

The evaporator 200 may be included in a refrigeration cycle (not shown). Then, the evaporator 200 may be configured so that cold refrigerant flows. To this end, the evaporator 200 may be connected to the refrigerant flow pipe P included in the refrigeration cycle as in the embodiment shown in FIG. Accordingly, cold refrigerant flowing in the refrigeration cycle can flow into the evaporator 200 through the refrigerant flow pipe P and flow.

The evaporator 200 may include an evaporator body 210 configured to allow a refrigerant to flow as in the embodiment shown in FIGS. 1 to 5. For this purpose, the evaporator main body 210 may be provided with a hole for forming a flow path through which cool refrigerant flows, as in the embodiment shown in FIGS. 2 to 5.

The evaporator main body 210 may include a refrigerant flow portion 211 and a heating portion insertion portion 212 as in the embodiment shown in FIGS.

The refrigerant flow portion 211 can flow cold refrigerant. In the embodiment shown in FIGS. 1 and 2, the evaporator unit 210 may have an 8-shaped cross-section. That is, two holes may be formed in the upper and lower portions of the evaporator main body 210, as shown in the illustrated embodiment. The hole formed at the lower portion may be a refrigerant flow portion 211 through which the refrigerant flows. As described above, the evaporator main body 210 having an 8-shaped cross section can be formed by extrusion processing.

3 and 4, a single hole may be formed in the evaporator main body 210. As shown in FIG. 3, the heating unit 300 may be inserted into a part of the hole formed in the evaporator unit 210. In this case, as shown in FIG. Therefore, in this embodiment, the remaining portion of the one hole formed in the evaporator main body 210 except for the portion where the heating portion 300 is inserted to be in contact may be the refrigerant flow portion 211.

4, the refrigerant flow pipe 220 may be inserted into the one hole formed in the evaporator body 210 so as to be in contact with the heating part 300. In addition, as shown in FIG. Therefore, in this embodiment, the portion of the evaporator body 210 inserted into the refrigerant flow pipe 220 in contact with the refrigerant flow pipe 220 may be the refrigerant flow portion 211.

The heating portion insertion portion 212 of the evaporator main body 210 may be integrated with the refrigerant flow portion 211. [ For example, the evaporator main body 210 of the embodiment shown in FIG. 2 is formed into an 8-shaped cross-section by extrusion processing so that the refrigerant flow portion 211 and the heating portion insertion portion 212 can be formed integrally. 3 and 4, the refrigerant flow portion 211 and the heating portion insertion portion 212 can be formed integrally with each other by the drawing process. However, the structure in which the refrigerant flow portion 211 and the heating portion insertion portion 212 are integrally formed is not limited to this, and any well-known configuration is possible.

The heating part 300 may be inserted into the heating part insertion part 212 of the evaporator body 210 so as to be in contact with the heating part insertion part 212 as in the embodiment shown in FIGS. In the embodiment shown in FIG. 2, the hole formed in the upper portion of the evaporator body 210 may be the heating portion insertion portion 212, as described above. The heating unit 300 may be inserted into the hole formed in the upper portion of the evaporator body 210 so as to be in contact with the evaporator body 210, as shown in the illustrated embodiment. The insulator 330 that is included in the heating unit 300 and covers the heater 310 of the heating unit 300 is inserted into the heating unit inserting unit 212 including the hole formed in the upper part of the evaporator body 210, As shown in Fig.

3 and 4, when a single hole is formed in the evaporator body 210, the heating part 300 is inserted into a part of one hole formed in the evaporator body 210 so that the heating part 300 is inserted . The heating portion 300 may be inserted into the heating portion insertion portion 212 of the evaporator body 210 to be in contact with the heating portion 300. In the illustrated embodiment, the heater insertion tube 320, which is included in the heating unit 300 and is inserted to be in contact with the heater 310, is inserted in contact with the heating unit insertion unit 212 of the evaporator body 210.

4, the evaporator 200 may further include a refrigerant flow pipe 220. The refrigerant flow pipe 220 can flow cold refrigerant. The refrigerant flow pipe 220 is included in the refrigerant flow portion 211 and the heating portion 300 of the evaporator body 210 and the heater 310 of the heating portion 300 is inserted Can be inserted into contact with the heater insertion tube (320).

5, the evaporator main body 210 and the heater insertion pipe 320, which is included in the heating unit 300 and into which the heater 310 of the heating unit 300 is inserted, is welded And can be integrally formed. For example, both the evaporator main body 210 and the heater insertion pipe 320 are made of copper, and the evaporator main body 210 and the heater insertion pipe 320 can be integrally formed by brazing welding have. However, in the same construction as the embodiment shown in FIG. 5, the welding for integrally forming the evaporator main body 210 and the heater insertion pipe 320 is not limited to the above-described brazing welding, .

The heating unit 300 may be integrated with the evaporator 200. Accordingly, when the evaporator 200 is heated by the heater 300, heat transfer from the heater 300 to the evaporator 200 may be performed while minimizing heat loss. The amount of heat transferred from the heating section 300 to the evaporation section 200 can be larger than that of the conventional configuration in which the heating section 300 and the evaporation section 200 are not integrated. The ice is removed from the heating unit 300 during deicing of the ice generated in conjunction with the evaporator 200 through the evaporator 200 and the ice is heated by the immersion member 400 connected to the evaporator 200 Lt; / RTI >

Therefore, even when the evaporator 200 is heated by the heating unit 300 at a temperature lower than the conventional temperature at which the heating unit 300 and the evaporator 200 are not integrally formed, You can rinse the ice. That is, even if the heating temperature of the heating unit 300 is relatively low, ice can be removed even if the heating temperature is about 30 ° C to 40 ° C, for example.

In this way, since the heating temperature of the heating unit 300 is lowered, a safety accident such as a user's image due to overheating of the heating unit 300 may not occur.

Since the heat is transferred from the heating unit 300 to the ice through the evaporator 200, the ice can be scraped even if the cold refrigerant flows into the evaporator 200. That is, the ice can be scraped even without stopping the operation of the compressor (not shown) included in the refrigeration cycle for ice scooping as in the prior art.

Therefore, since the stop and drive of the compressor need not be repeated for deicing of ice as in the conventional art, the energy consumption efficiency can be increased. That is, since much energy is not required for re-driving the compressor as in the prior art, the energy consumption efficiency can be increased.

Also, since the waiting time for the compressor to be restarted is not required and the waiting time for the temperature of the refrigerant to drop to the temperature for the ice-making is not required as in the conventional art, the entire ice-making time can be reduced. In this way, the ice making cycle can also be reduced. Whereby the ice making amount of the ice maker can be increased.

2, the heating unit 300 is disposed at an upper portion of the evaporator unit 210 having a shape of '8' in cross section, such that the evaporator unit 200 and the heating unit 300 are integrally formed. And can be inserted into contact with the heating portion insertion portion 212 of the evaporator main body 210 including the formed hole.

In addition, as shown in FIGS. 3 and 4, it can be inserted into the heating part insertion part 212 of the evaporator main body 210 having one hole so as to be in contact with the heating part insertion part 212. 5, the heating unit 300 includes a heater insertion tube 320 inserted into the heater 310 so as to be in contact with the evaporator unit 210, The heater insertion pipe 320 of the unit 300 may be integrally formed by brazing.

The heating unit 300 may include a heater 310 as shown in FIGS. 1 to 5. The evaporator 200 can be heated by the heater 310. In this way, ice (I) generated in association with the evaporator (200) can be removed.

For example, as shown in FIGS. 1 and 2, one or more immersion members 400 may be connected to the evaporator body 210 of the evaporation unit 200. As a result, the coolant may flow to the immersion member 400. And, the immersion member 400 can be immersed in water. A tray member (not shown) is positioned under the immersion member 400 and water is supplied to the tray member to immerse the immersion member 400 in the water contained in the tray member. Ice can be generated in the immersion member 400 by heat transfer from the water contained in the tray member to the coolant refrigerant flowing in the immersion member 400.

In this configuration, when the evaporator 200 is heated by the heater 310, ice generated in the immersion member 400 can be separated from the immersion member 400, that is, can be removed. The heater 310 may be configured to heat the evaporator 200 by electricity. To this end, the heater 310 may include, for example, a heat wire. However, the structure of the heater 310 is not particularly limited, and any known structure can be used as long as the evaporator 200 can be heated.

The heating unit 300 may further include a heater insertion tube 320 as shown in FIGS. The heater 310 may be inserted into the heater insertion tube 320 so as to be in contact with the heater insertion tube 320. 3 and 4, the heater insertion tube 320 may be inserted into the heating part insertion part 212 included in the evaporator body 210 of the evaporator 200 so as to be in contact with the heating part insertion part 212 . Accordingly, the heat can be transferred from the heater 310 to the immersion member 400 through which the ice is generated, through the evaporator unit 210.

3, the evaporator main body 210 of the evaporator 200 and the heater inserting pipe 320 of the heating unit 300 may be formed together by drawing. 4, when the refrigerant flow pipe 220 is inserted into the refrigerant flow pipe 211 included in the evaporator body 210 of the evaporator 200 so as to be in contact with the evaporator unit 210, The heater inlet pipe 320 of the heating unit 300 and the refrigerant flow pipe 220 of the evaporator 200 may be formed together by drawing.

5, the evaporator main body 210 of the evaporator 200 and the heater insertion pipe 320 of the heating unit 300 may be integrally formed by welding such as brazing welding.

2, when the heater 310 is configured to heat the evaporator 200 by electric power as described above, the heater 310 and the heating portion inserting portion of the evaporator portion main body 210, as in the embodiment shown in FIG. 2, And an insulator 330 may be provided between the first and second electrodes 212 and 212. The insulator 330 may be provided between the heater 310 and the heater inserting pipe 320, as shown in FIGS. Accordingly, electricity can be prevented from being transmitted from the heater 310 to the outside. In such an insulator 330, electricity may not be transmitted, but heat may be transmitted.

On the other hand, the heating temperature of the heating unit 300 may be different depending on the portion of the evaporator 200. This makes it possible to smoothly carry out ice scavenging.

In a portion of the evaporator 200 where the temperature of the heating portion 300 is not different from that of the evaporator 200 to the portion of the evaporator 200 where the temperature of the refrigerant flowing through the evaporator 200 is relatively low, , Heat transfer from the heating unit 300 to the evaporator 200 is not performed to such an extent that the ice is removed. Therefore, ice can not escape at this part. In the portion of the evaporator 200 where the temperature of the refrigerant flowing through the heat transfer is relatively high, ice can be melted more than necessary. Therefore, the ice of ice can not be evenly distributed.

Therefore, by varying the heating temperature of the heating unit 300 in different parts of the evaporator 200, that is, in the portion of the evaporator 200 requiring a lot of heat for deaeration, the heating temperature is increased, A portion of the evaporator 200 which is not required can lower the heating temperature so that ice can be evenly ice-cooled.

In this case, the heating temperature of the heating unit 300 may vary depending on the temperature of the refrigerant flowing through the evaporator 200. For example, as described above, the heating temperature of the heating unit 300 in the portion of the evaporator 200 where the temperature of the refrigerant is relatively low may be relatively high. The heating temperature of the heating unit 300 in the portion of the evaporator 200 where the temperature of the refrigerant is relatively high may be relatively low.

6, the heating temperature of the heating part 300 in the first part 200a of the evaporation part 200 into which the refrigerant flows before the heat transfer with water is relatively relatively high Can be high. Since the temperature of the refrigerant flowing through the first portion 200a of the evaporator 200 is relatively low, a relatively large amount of heat is required to de-ice the ice generated in association with the refrigerant.

The heating temperature of the heating unit 300 in the second portion 200b of the evaporator 200 through which the refrigerant having heat transferred to the water flows out may be relatively low. Since the temperature of the refrigerant flowing through the second portion 200b of the evaporator 200 is relatively high, relatively little heat is required for deicing the ice produced in association with the relatively high temperature.

The heating temperature of the heating part 300 in the third part 200c of the evaporation part 200 between the first part 200a and the second part 200b is the heating temperature of the first part 200a And the heating temperature in the second portion 200b.

However, the distribution of the heating temperature of the heating unit 300 for each part of the evaporator 200 is not limited to the above-described one, and any distribution can be used as long as the ice is uniformly scattered.

The heater 310 of the heating unit 300 may use the heating heater 310 in order to make the heating temperature distribution of the heating unit 300 different for each part of the evaporator 200 as described above . That is, the heater 310 included in the heating unit 300 integrated with the evaporator 200 includes the first portion 200a, the third portion 200c, and the second portion 200b of the evaporator 200a, The amount of heat generated may be different.

For example, the portion of the heater 310 that heats the first portion 200a of the evaporator 200 has the largest amount of heat generation, the portion of the heater 310 that heats the second portion 200b has the smallest amount of heat And the portion of the heater 310 that heats the third portion 200c may be the amount of heat generated therebetween. Accordingly, the heating temperature distribution of the heating unit 300 can be made different for each part of the evaporator 200.

As described above, when the evaporator for an ice maker according to the present invention is used, the evaporator for cooling cold refrigerant and the heating unit for heating the evaporator can be integrally formed. And even if the heating temperature of the heating unit is relatively low, deicing of ice can be carried out, and a safety accident such as a user's image due to overheating of the heating unit may not occur.

In addition, ice can be removed even in the state where cold refrigerant flows, energy consumption efficiency can be increased, the total ice-making time can be reduced, ice-making amount of the icemaker provided with the evaporator for ice- The ice can be uniformly removed.

The above-described embodiments of the evaporator for an ice-maker may not be limited to the above-described embodiments, but all or a part of the embodiments may be selectively combined so that various modifications may be made to the embodiments .
