Description

Evaporator for ice making and manufacturing method of the evaporator for ice making {Evaporator for ice making and manufacturing method thereof}

The present invention relates to an evaporator for ice making and a method of manufacturing the evaporator for ice making, and more specifically, to an evaporator for ice making capable of producing spherical or hemispherical ice and a method of manufacturing the evaporator for ice making.

In general, an ice maker is a device that cools water to the freezing point of 0℃ or lower to make ice and supplies it to the user. These ice makers are installed in refrigerators or ice water purifiers that require ice. In an ice maker, water is sprayed onto an ice-making frame equipped with a cooling unit such as an evaporator or an evaporator through which a refrigerant flows, or an immersion-type ice maker in which the immersion member through which the refrigerant flows is submerged in water to create ice on the immersion member. There is a spray-type ice maker that creates ice, or a flow-type ice maker that creates ice in the ice-making mold by allowing water to flow through an ice-making frame equipped with a cooling unit such as an evaporator through which a refrigerant flows.

Conventional ice makers are disclosed in Coway Co., Ltd.'s Korean Patent Publication Nos. 2020-0020309 and 2016-0084930. These ice makers are configured to produce ice by contacting an evaporation tube through which refrigerant flows to a hemispherical ice-making groove to cool the ice-making frame. However, in these ice makers, a refrigerant pipe is interposed between the refrigerant and the ice making frame, so the refrigerant and the ice making frame cannot come into direct contact, so there is a problem in that the ice making frame cannot be cooled at a high heat transfer rate.

Additionally, these ice makers are configured so that a refrigerant pipe through which the refrigerant flows is located on the upper side of the ice making frame to cool the ice making frame. However, in these ice makers, an air hole through which external air can flow in cannot be formed in the upper part of the ice making frame, so the effective atmospheric pressure acts in the inner direction of the ice making frame, so the manufactured ice cannot be separated smoothly. There is.

In addition, in these ice makers, the evaporation tube for circulating the refrigerant and the ice-making frame for forming ice must be manufactured separately, so it costs a lot of money to procure individual components, and furthermore, the refrigerant must be used to cool the ice-making frame. The evaporation tube and the ice-making frame must be combined separately, and the combined structure is complicated due to the large number and type of components, which increases manufacturing costs.

The ice-making evaporator according to an embodiment of the present invention is an evaporator for producing spherical or hemispherical ice. Referring to Figures 1 to 3, the evaporator 1 for ice making according to an embodiment of the present invention includes a lower plate 110, a plurality of upper ice making frames 120, an upper plate 210, side plates 220 and 230, and a closing stopper ( 300).

In this embodiment, a plurality of upper ice making frames 120 are provided so that hemispherical ice can be manufactured. According to one embodiment of the present invention, hemispherical ice with a convex upward shape can be manufactured using a hemispherical upper ice-making frame 120. To this end, a flow space through which cold refrigerant can flow is formed around the upper ice making frame 120.

According to one embodiment of the present invention, the flow space includes side plates 220 and 230 spaced apart on both sides of the outer portion of the plurality of upper ice making frames 120, and a lower plate 110 and an upper plate disposed below and above the side plates 220 and 230.

Figure 10 is a perspective view of an evaporator for ice making according to an embodiment of the present invention cut along line III-III' of Figure 8. Figure 11 is a transverse cross-sectional view of an evaporator for ice making according to an embodiment of the present invention.

3 to 5, an evaporator for ice making according to an embodiment of the present invention includes a plurality of upper ice making frames 120.

The upper ice making frame 120 is a component that provides a frame in which the shape of ice is formed, and may be made of a material with high thermal conductivity. In the illustrated embodiment, the outer portion of the upper ice making frame 120 may have a hemispherical shape convex upward, but the shape is not particularly limited as long as the outer portion can be cooled by refrigerant.

A hemispherical ice-making groove 123 is formed inside the upper ice-making frame 120. As shown in FIGS. 3 and 4, the ice-making groove 123 is open downward, and an opening that communicates the ice-making groove 123 with the outside may be provided at the lower end of the upper ice-making frame 120.

When water flows into the ice-making groove 123 through the opening, hemispherical ice may be produced on the inner wall of the ice-making groove 123. For this purpose, a spray device (not shown) for spraying water into the ice-making groove 123 may be provided on the opening side of the upper ice-making frame 120.

An air hole 121 through which air can flow in from the outside may be formed on the inner wall of the ice-making groove 123. The air hole 121 serves to introduce external air between the inner wall of the ice making groove 123 and the ice during the process of removing ice from the upper ice making frame 120.

When outside air flows between the inner wall of the ice-making groove 123 and the ice, negative pressure can be prevented from forming between the inner wall of the ice-making groove 123 and the ice, so the ice can be smoothly discharged to the outside of the ice-making groove 123. .

At this time, the air hole 121 is located at a higher position upward from the opening than the upper plate 210, which will be described later. That is, as shown in FIG. 4, the height H1 at which the air hole 121 is spaced upward from the opening is higher than the height H2 at which the upper plate 210 is spaced upward from the opening. Preferably, the air hole 121 may be formed on the uppermost side of the upper ice making frame 120.

Accordingly, even though the flow spaces A and C formed between the upper plate 210 and the lower plate 110 are located above the opening of the upper ice making frame 120, the flow spaces A and C and the air holes 121 ) do not interfere with each other, so the function of the above-described air hole 121 can be performed smoothly.

Meanwhile, according to the illustrated embodiment, the plurality of upper ice-making frames 120 is comprised of four, and the four upper ice-making frames 120 may be arranged side by side with each other. As shown in FIG. 3, a plurality of upper ice making frames 120 are arranged in a row. However, the arrangement method is not particularly limited.

Additionally, in this embodiment, the plurality of upper ice making frames 120 have the same shape, but their shapes do not necessarily have to be the same, and may have different shapes. For example, the ice making groove 123 of one of the plurality of upper ice making frames 120 may have a different size from that of any other ice making groove 123.

In addition, in this embodiment, the case where the number of the plurality of upper ice making frames 120 is four is illustrated, but the number of the plurality of upper ice making frames 120 is not limited to four, and the number may be provided as one or more. there is.

Meanwhile, referring to FIGS. 4 to 7 , the plurality of upper ice making frames 120 are coupled to the lower plate 110 and the upper plate 210 that are parallel to each other. The lower plate 110 and the upper plate 210 are configured to fix the relative positions between the plurality of upper ice making frames 120 and form flow spaces A and C outside the upper ice making frames 120.

To this end, a plurality of first coupling holes 111 may be formed in the lower plate 110, and a plurality of second coupling holes 211 may be formed in the upper plate 210. The plurality of first and second coupling grooves 111 and 211 may be arranged in a row corresponding to the plurality of upper ice making frames 120.

The outer portion of the upper ice making frame 120 is coupled through the first and second coupling grooves 111 and 211. Accordingly, the opening of the upper ice making frame 120 is located on the lower side of the lower plate 110, and the upper end of the outer portion of the upper ice making frame 120 is exposed to the upper side of the upper plate 210.

As shown in FIG. 4, flow spaces A and C through which refrigerant flows are formed between the lower plate 110 and the upper plate 210. The lower plate 110 and the upper plate 210 have a higher thermal conductivity than the upper ice making frame 120 so that relatively little external heat energy is transmitted to the flow space (A, C) through the lower plate 110 and the upper plate 210. It can be made of low-cost materials. Of course, for manufacturing convenience, the lower plate 110 and the upper plate 210 may be made of the same material as the upper ice making frame 120.

Meanwhile, the location where the lower plate 110 and the upper plate 210 are coupled and their mutual arrangement can be appropriately designed depending on the flow rate of refrigerant passing through the flow spaces A and C. For example, in this embodiment, the lower plate 110 is located at a height H3 that is somewhat spaced upward from the opening of the upper ice making frame 120, but may be located closer to the opening of the upper ice making frame 120. It may be possible. In addition, the upper plate 210 is located at a height H2 that is somewhat spaced upward from the lower plate 110, but may be located closer to the upper end of the upper ice making frame 120.

Accordingly, the vertical height of the flow spaces (A, C) increases, and the flow rate of the refrigerant flowing through the flow spaces (A, C) can increase. However, even in this case, it would be desirable for the upper plate 210 to be positioned lower than the air hole 121 as described above.

Referring to FIGS. 4 and 5 , a separation plate 130 may be disposed between the lower plate 110 and the upper plate 210. The separation plate 130 is configured to partition the flow space formed between the lower plate 110 and the upper plate 210. To this end, the lower and upper portions of the separation plate 130 may be coupled to the lower plate 110 and the upper plate 210, respectively.

The separator plate 130 may be made of a material with low thermal conductivity so that less heat exchange occurs between refrigerants flowing in the partitioned space. Of course, for manufacturing convenience, the separation plate 130 may be formed of the same material as the upper ice making frame 120.

The separation plate 130 includes a middle partition wall 132 located between the plurality of upper ice making frames 120 and an end located outside the upper ice making frame 120 located at an end of the plurality of upper ice making frames 120. It may consist of a side partition 134.

The middle partition 132 is disposed between adjacent upper ice-making frames 120 among the plurality of upper ice-making frames 120 and partitions the space between the lower plate 110 and the upper plate 210.

In the illustrated embodiment, the middle partition wall 132 extends in a direction parallel to the arrangement direction of the plurality of upper ice-making frames 120, and both sides of the extension direction are coupled to the outer portions of the upper ice-making frames 120, respectively.

To this end, the middle partition 132 has a trapezoidal shape whose width becomes longer toward the top, and both sides may be formed to be somewhat concave corresponding to the outer portion of the upper ice making frame 120.

The end-side partition wall 134 is configured to partition a portion of the flow space through which the refrigerant enters and exits, thereby preventing the refrigerant flowing into the flow space and the refrigerant flowing out of the flow space from mixing with each other.

The end side partition 134 may extend parallel to the lower plate 110 and the upper plate 210 on the outer side of the upper ice making frame 120. In the illustrated embodiment, the end-side partition wall 134 extends parallel to the extension direction of the middle-side partition wall 132.

Referring to FIGS. 6 and 7 , first and second side plates 220 and 230 are disposed on both sides of the separation plate 130 in the extension direction so as to entirely surround the sides of the plurality of upper ice making frames 120 .

The first and second side plates 220 and 230 are configured to isolate the flow space between the upper plate 210 and the lower plate 110 from the outside. For this purpose, the lower and upper sides are formed by the lower plate 110 and the upper plate 210, respectively. can be combined with

At this time, the first and second side plates 220 and 230 may be made of a material with low thermal conductivity in order to minimize the transfer of external heat to the flow space. Of course, the first and second side plates 220 and 230 may be made of the same material as the upper ice making frame 120 in consideration of manufacturing convenience.

In the illustrated embodiment, the first side plate 220 includes a plurality of first side walls 222 located on the right side of the outer portion of the plurality of upper ice making frames 120, and a plurality of first side walls 222 located between the plurality of first side walls 222. It may be composed of a first middle side connecting wall 224 and a pair of first end side connecting walls 226 respectively located on end sides in the extension direction of the first side plate 220.

Referring to FIGS. 8 and 11, the refrigerant discharged from the refrigerant inlet pipe 312 flows through the inlet space A1 and then flows into the first transit space A2 located on the circumference of the upper ice making frame 120. . At this time, since the inlet space (A1) is partitioned from the outlet space (C1) by the end partition 134, the refrigerant flowing in the inlet space (A1) cannot directly flow into the outlet space (C1).

The refrigerant flowing into the first transit space A2 flows along the circumference of the right side of the upper ice making frame 120 and performs a cooling function. At this time, since the refrigerant is in direct contact with the upper ice-making frame 120, it can absorb the heat of the upper ice-making frame 120 through a high heat transfer rate.

The refrigerant flowing through the first transit space A2 of the upper ice making frame 120 flows into the first connection space A3 provided between adjacent upper ice making frames 120. The refrigerant flowing into the first connection space (A3) flows into the first transit space (A2) of the neighboring upper ice making frame (120) and performs the above-described cooling function again.

At this time, since the first connection space (A3) is isolated from the second connection space (C3) by the middle partition 132, the refrigerant flowing through the first connection space (A3) directly flows into the second connection space (C3). It can't be. In this way, the refrigerant sequentially flows through the first transit space A2 of the upper ice-making frames 120 arranged in a row, and cools the entire right side of the upper ice-making frames 120.

Thereafter, the refrigerant sequentially flows through the second transit space C2 and the second connection space C3 to cool the entire left side of the upper ice making frame 120. The refrigerant that cools the entire left side of the upper ice making frame 120 flows into the outflow space C1 and is then discharged to the outside through the discharge pipe 316.

As such, in this embodiment, the refrigerant sequentially flows through the first and second transit spaces A2 and C2 located around the plurality of upper ice-making frames 120, so that the outer portion of the plurality of upper ice-making frames 120 can be cooled overall. In addition, in this embodiment, the refrigerant sequentially cools the plurality of upper ice-making frames 120 and then rotates to sequentially cool the plurality of upper ice-making frames 120 again, so that the refrigerant comes into contact with the upper ice-making frame 120. Time can be increased.

Therefore, according to this embodiment, the cooling ability of the refrigerant can be sufficiently exerted and ice can be efficiently produced.

Meanwhile, after ice is formed in the plurality of upper ice making frames 120, heat gas may flow along the flow spaces (A, C) and the turning space (B). When the heat gas increases the temperature of the plurality of upper ice-making frames 120, the outer portion of the ice in contact with the ice-making groove melts, and the produced ice is separated from the ice-making groove by a predetermined force, for example, gravity. You can.
