Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an ice making machine, and more particularly, to an ice making plate for cooling ice making water to produce ice.
[0002]
[Prior art]
Usually, an ice maker is a device that cools ice making water supplied from inside and outside of the ice maker body to generate ice, and FIG. 1 shows an example of a normal ice maker.
[0003]
Referring to FIG. 1, a conventional ice maker 100 includes an ice maker main body 110, a cooling system, an ice maker unit 130, and an ice storage 120. The cooling system includes a compressor 190, a condenser (not shown), and an evaporator tube 180, and cools the periphery of the evaporator tube 180 to generate ice in the ice making unit 130 when the evaporator is driven. The ice storage 120 is for storing ice generated by the ice making unit 130 and discharged from the ice making unit 130.
[0004]
Referring to FIG. 2, the ice making unit 130 includes an ice making plate 140 and a tray 160. Reference numeral 170 denotes a base frame that holds the tray 160. Reference numeral 175 denotes a rotation motor that rotates the tray 160 so that the ice is not obstructed by the tray 160 when ice production by the ice making projection 150 is completed.
[0005]
The tray 160 stores ice making water supplied from inside and outside of the ice making machine main body 110, and is arranged below the ice making plate 140 described later.
[0006]
The ice making plate 140 is connected to a condenser (not shown) and a compressor 190 at both ends thereof, is provided on an evaporating tube 180 serving as a part of a cooling system, and is disposed on an upper part of the ice storage 120. An ice making projection 150 is provided. The ice making plate 140 having such a configuration is cooled by the evaporating tube 180 when the cooling system is driven, and at the same time, ice is generated such that the ice making projections 150 are immersed in the ice making water stored in the tray 160. At this time, the connection between the ice making plate 140 and the evaporating tube 180 is usually made by another connecting means such as solder 185 (FIG. 3).
[0007]
However, the conventional ice making unit 130 configured as above has a problem that the cooling efficiency of the evaporating tube 180 is reduced because the evaporating tube 180 must simultaneously cool the entire portion of the ice making plate 140 and the ice making projections 150. . Further, when the ice making plate 140 is cooled by the evaporating tube 180, there is a problem that the cooling efficiency of the evaporating tube 180 is further reduced by the dew generated on the upper surface of the ice making plate 140.
[0008]
In order to solve the above-described problem, a method of forming a discharge hole (not shown) in the entire remaining portion of the ice making plate 140 where the ice making projection 150 is not installed has been used (see Patent Document 1).
[0009]
However, when such a method is used, the volume of the ice making plate 140 is reduced, and a sufficient effect is obtained to remove dew generated on the upper surface of the ice making plate 140 when the cooling system is driven. Cooling of 150 is provided only by the evaporator tube 180 and a portion of the ice making plate 140 that connects the ice making projections 150 in the direction of the main axis of the evaporator tube 180 and perpendicular to the main axis. Thereby, the temperature becomes the same between the ice making projections 150 disposed on the upstream side and the downstream side of the evaporating tube 180, that is, the size of each of the ices generated by the ice making projections 150 is made the same by slowing down the thermal equilibrium. There is a problem that cannot be done.

[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For reference, before describing an embodiment of the present invention, components of an ice maker having the same configurations and functions as those of the conventional ice maker shown and described in FIGS. Reference numerals are given, and the detailed description is omitted.
[0018]
4 and 5, an ice making machine 100 (see FIG. 1) according to a preferred embodiment of the present invention includes an evaporating tube 180 and an ice making plate 240.
[0019]
Both ends of the evaporator tube 180 are connected to a compressor 190 (see FIG. 1) and a condenser (not shown), respectively, so as to play a part of a cooling system provided inside the ice making machine main body 110 (see FIG. 1). When the cooling system is driven, the surroundings are cooled by the cool air of the refrigerant circulating inside the evaporating pipe 180.
[0020]
The ice making plate 240 includes an ice making plate main body 241 and an ice making projection 250. The ice making plate main body 241 is connected to the evaporating tube 180 and is cooled when the evaporating tube 180 is cooled. A plurality of ice making projections 250 are provided below the ice making plate body 241 to be cooled when the ice making plate body 241 is cooled, and at the same time, are immersed in ice making water stored in the tray 160 (see FIG. 1) to generate ice. .
[0021]
The ice making plate main body 241 is desirably formed of a metal material having good thermal conductivity such as copper (Cu) so that cold air can be easily absorbed from the evaporating tube 180. The ice making projection 250 is formed of the ice making plate main body 241. It is desirable that the heat transfer efficiency of the ice making plate 240 is not reduced.
[0022]
The evaporating tube 180 is desirably press-pressed to a mounting groove 241a (see FIG. 6) in which the evaporating tube 180 is formed on the upper surface of the ice making plate main body 241. According to this, heat loss due to the conventional solder 185 (see FIG. 3) used for coupling the ice making plate main body 241 and the evaporating tube 180 can be prevented. Further, the upper surface of the ice making plate 240 is raised along the edge of the mounting groove 241a of the ice making plate 240 by the above-described press-pressing, and the projection 241b (see FIG. The contact area between the outer peripheral surface of the ice making plate body 241 and the outer peripheral surface of the ice making plate body 241 is increased, so that the cooling efficiency of the evaporating tube 180 can be improved.
[0023]
On the other hand, the ice making plate main body 241 includes a first connecting portion 243 connecting the ice making projections 250 arranged adjacent to each other along the longitudinal direction of the ice making plate main body 241, that is, along the main axis directions X1, X2, X3 of the evaporating tube 180. A second connecting portion 244 connecting the ice making projections 250 arranged adjacent to each other along a direction perpendicular to the main axis directions X1, X2, X3 of the evaporating tube 180, and connecting the first and second connecting portions 243, 244. And a third connecting portion 245 disposed between the first and second connecting portions 243 and 244.
[0024]
As shown in FIGS. 6 and 7, the ice making plate main body 241 in the present embodiment is formed such that the first connecting portion 243 and the thicknesses t1, t2, and t3 of the second connecting portion 244 and the third connecting portion 245 are different. Is done. In particular, the third connection part 245 is formed to have a smaller thickness t3 than the first and second connection parts 243 and 244, and the first and second connection parts 243 and 244 are formed to have the same thickness t1 and t2. At this time, at least one or more through-holes 249 (see FIG. 4) penetrate through a part of the third connecting portion 245 to discharge dew generated on the upper surface of the ice making plate 240 when cooling the ice making plate 240 and lowering the cooling efficiency. Preferably, it is formed. The number and shape of the through holes 249 may be variously changed based on the efficiency of transmitting cold air by the evaporating tube 180. The configuration of such an ice making plate 240 is not necessarily limited to the present embodiment. That is, if the thickness of the third connection part 245 is smaller than the thicknesses of the first and second connection parts 243 and 244, the first connection part 243, the second connection part 244 and the third connection part 245 are respectively formed. Of course, it can be formed in various thicknesses.
[0025]
According to the configuration of the ice making plate 240, the cool air transmitted from the upstream side of the evaporating tube 180 to the downstream side of the evaporating tube 180 is minimized from being unnecessaryly used to cool the third connection portion 245. it can. That is, the volume of the third connecting portion 245 is smaller than that of the related art, and the amount of cool air required for cooling the third connecting portion 245 is smaller than that of the related art. As a result, the cold air stored as described above is transferred from the ice making projection 250a (see FIG. 4) disposed upstream of the evaporating tube 180 to the ice making projection 250b (see FIG. 4) disposed downstream of the evaporating tube 180. A larger amount of light can be transmitted through the first and second connection parts 243 and 244. Therefore, the thermal equilibrium at which the temperatures of the ice making projections 250a and 250b become substantially the same when the ice making plate 240 is cooled is more quickly established, and the ice making projections 250a and 250b are generated when the ice is generated by driving the cooling system. Ice can be prevented from being formed in different sizes.
[0026]
On the other hand, the thermal equilibrium between the ice making protrusions 250a and 250b is slower when the discharge hole (not shown) is formed in the third connection part 245 as in the related art than when the ice making plate 240 according to the present invention is used. This occurs because the cold air transmission to the first and second connection portions 243 and 244 by the third connection portion 245 is blocked at the source by a conventional exhaust hole (not shown). In order to solve this, in the present invention, the third connecting portion 245 is formed to be thinner than the first and second connecting portions 243, 244, and the thickness of the first and second connecting portions 243, 244 is reduced to half of the thickness t1, t2. According to this, the cooling air loss due to the cooling of the third connection part 245 can be minimized, and the first and second connection parts 243 by the third connection part 245 can be minimized. The heat transfer between the 244 is better.
[0027]
【The invention's effect】
As described above, according to the present invention, by making the thickness of a part of the ice making plate thinner than before, the thermal equilibrium between the ice making projections can be quickly obtained.
[0028]
Thereby, it is possible to prevent the sizes of the ice pieces formed on the respective ice making projections from being formed differently, and it is possible to prevent a decrease in efficiency of the cooling system caused by cooling an unnecessary portion of the ice making plate.
[0029]

On the contrary, those skilled in the art will appreciate that various changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
