Hereinafter, the operation of the first embodiment of the apparatus for producing ice and cold water using the thermoelectric element of the present invention will be described.

5 is a cross-sectional view showing the ice making process of the ice and cold water producing apparatus using the thermoelectric element according to the present invention, FIG. 6 is an enlarged view of the "A" Fig.

As shown in FIGS. 5 and 6, the thermoelectric elements 110, the ice-making unit 120, and the heat sink 130 are joined together by using the fastening member 140. As shown in FIGS. 5 and 6, The first block 122 of the ice making unit 120 and the second block 131 of the heat sink 130 are connected to each other in a state in which the ice making unit 120 is disposed on one side and the heat sink 130 is disposed on the second side. Is fixed to the thermoelectric element 110 with the fastening member 140 interposed therebetween.

Specifically, in a state in which the support portion 141 of the fastening member 140 is supported on the outer surface of the second block 131, the elastic portion 142 provided at both ends of the support portion 141 is bent and elastically compressed, The first block 122 and the second block 131 are fixed to the fixing hook formed on the side surface of the first block 122 by using the fixing portion 143 provided at the end of the elastic portion 142, The thermoelectric elements 110 are pressed toward the thermoelectric elements 110 by the elastic force of the thermoelectric elements 110. Thus, the utilization efficiency of the thermal energy can be improved.

Particularly, a plurality of fastening members 140 are disposed at positions corresponding to the thermoelectric elements 110, and the plurality of fastening members 140 are integrally formed by a connecting piece 144 connecting the neighboring supporting portions 141 . The first block 122 and the second block 131 are fixed with a plurality of thermoelectric elements 110 interposed therebetween by using a plurality of integrally formed fastening members 140, It is possible to provide an elastic force at a position corresponding to the thermoelectric element 110 through the elastic portion 142 formed in the thermoelectric element 110 so that the thermoelectric element 110 can be pressed and fixed. Therefore, even if a distortion or bending occurs due to thermal deformation in a partial region, Can be prevented. The connecting piece 144 connecting the plurality of fastening members 140 is formed to have a relatively small sectional area as compared with the supporting portion 141 so that only the central portion of the supporting portion 141 is connected, It is possible to prevent the elastic force or the fastening force of the portion 142 from affecting the adjacent fastening member 140. [ Since the plurality of fastening members 140 are integrally connected to each other through the connecting pieces 144, it is not only easy to assemble but also allows the fastening members 143 to be separated from the fixing hooks Since the assembly is released only by separating, it is possible to reduce the number of workpieces required for assembly and disassembly (see FIG. 3).

The thermoelectric element 110 interposed between the heat sink 130 and the freezing unit 120 by the fastening member 140 is connected to the first surface An endothermic action is performed and heat is generated on the second surface where the heat sink 130 is closely contacted.

That is, at the time of the icemaking, the water receiving portion 150 is rotated to the ice making position, and the lower end portion of the first block 122 of the ice making unit 120 is received in the receiving space of the ice making unit 120, The ice-making water is filled in the ice-making part 123 formed at the bottom of the first block 122 in the form of an ice-making space.

Since the freezing portion 123 of the first block 122 is rapidly cooled to about -20 degrees Celsius by the endothermic action of the first surface of the thermoelectric element 110, the inside of the freezing portion 123, The ice making machine 100 may be used to produce ice (I) having a shape corresponding to the ice making space by freezing the ice making water filled in the ice making unit 120, The water is cooled to about 5 degrees centigrade or less, so it becomes cold water (W) for drinking.

If vibration is provided toward the ice making part 123 by using the vibration generating part 160 disposed at a position corresponding to the ice making part 123 in the bottom part of the water receiving part 150 in the process of manufacturing the ice I, Since the bubbles in the ice-making water are removed during the manufacturing process of ice (I), clear and transparent ice (I) can be produced. The heat insulating pad 124 having a predetermined thickness disposed at the lower end of the first block 122 is disposed in a region other than the opening region of the ice making section 123 to limit the manufacturing position of the ice I , It is possible to continuously produce ice (I) having a predetermined shape.

The heat energy generated by the heat generated in the second surface of the thermoelectric element 110 is conducted to the heat radiating fin 133 through the second block 131 and the heat pipe 132, Respectively.

7, when the water receiving unit 150 is rotated to the ice making position to tilt the water receiving unit 150 for de-icing as described above, The cold water W is cooled down through the guide plate 151 and moved to the cold water storage unit 180 disposed below the water receiving unit 150 through the through holes 152. [

Next, when the electrode of the DC power source applied to the thermoelectric element 110 is switched, a heat generating action is performed on the first surface of the thermoelectric element 110, and an endothermic action is performed on the second surface thereof.

That is, when the thermal energy provided by the first surface of the thermoelectric element 100 heats the first block 122, the contact surface contacting the ice-making portion 123 of the ice I melts down, And is separated from the ice part 123. The first block 122 is formed with an air passage connecting the outer surface of the first block 122 and the upper end of the ice maker 123 so that the ice I can be easily separated from the ice maker 123 can do.

The ice I falling off the ice making unit 123 and falling down to the lower portion of the ice making unit 120 can not pass through the through hole 152 formed in the guide plate 151 of the water receiving portion 150, And then moves to the ice storage part 170 disposed on the lower side of the water receiving part 150 along the ice storage part 151.

The first block 122 has a through-hole formed at a position corresponding to the thermoelectric element 110 of the first block 122 And is inserted and fixed in the insertion hole 122b. At this time, in order to improve the thermal conductivity of the heat pipe type ice-making part 123 'and the first block 122, the ice-making part 123' is fixed to the insertion hole 122b in a shrinkage fit manner, It is preferable that they are brought into contact with or adjacent to the first surface of the thermoelectric element 110.

That is, since the ice-making unit 123 according to the first embodiment is formed in a concave shape, the shape of the ice-making space 123 can be easily set by changing the shape of the ice-making space. The ice making part 123 'according to the example has an advantage that the use efficiency of heat energy can be improved by using a heat pipe, and thus the time for ice making and ice-making can be shortened.

The process of ice-making and de-icing using the ice-making unit 123 'configured as described above will be described below.
