FIGS. 7 and8 , thetemperature sensor part 1260 may be disposed on the rear surface of thesecond tray 1240, among theice making cells 1241. In the present disclosure, the lines in the shaft direction of thesecond tray 1240 are defined as columns, and the lines in a direction orthogonal to the shaft direction of thesecond tray 1240 are defined as rows. Thesecond tray 1240 may have 3 or greater of odd numbers of lines ofice making cells 1241. - The
temperature sensor part 1260 may be disposed amongice making cells 1241 that constitute a middle line among odd numbers of columns. Since thetemperature sensor part 1260 is disposed in the middle portion of the columns, a temperature measured by thetemperature sensor part 1260 may be treated as a representative temperature of the entireice making cells 1241 formed in thesecond tray 1240. - Additionally, a distance among the
ice making cells 1241 in asensor accommodation part 1244 in which thetemperature sensor part 1260 is disposed may be greater than in another portion. As described above, thesecond ice maker 1200 may generate ice that is relatively small. To this end, the sizes of theice making cells 1241 may decrease. As a result, a distance among theice making cells 1241 may decrease. In one embodiment, since a distance among theice making cells 1241 in thesensor accommodation part 1244 is greater than in another portion, thetemperature sensor part 1260 may be accommodated in thesensor accommodation part 1244. - Further, the
sensor accommodation part 1244 may be disposed closer to the other end of thesecond tray 1240, which is far from the secondice maker inlet 1232 into which cold air flows and, than to one end of thesecond tray 1240, which is close to the secondice maker inlet 1232. For example, a distance between thesensor accommodation part 1244 and one end of thesecond tray 1240 may account for 60 to 90 % of a distance between one end of thesecond tray 1240 and the other end of thesecond tray 1240. Preferably, a distance between thesensor accommodation part 1244 and one end of thesecond tray 1240 may account for 70 % of a distance between one end of thesecond tray 1240 and the other end of thesecond tray 1240. In the portion of thesensor accommodation part 1244, the phase of water may change last. To find the completion of the change in the phase of water in the entiresecond tray 1240, a temperature in the portion of thesensor accommodation part 1244 is measured. - Referring to
FIGS. 8 and9 , thetemperature sensor part 1260 may comprise atemperature sensor 1261, afirst insulation material 1262, asecond insulation material 1263 and aguide 1264. - The
temperature sensor 1261 may measure a temperature, and output the measured temperature. - The
first insulation material 1262 may be disposed between thetemperature sensor 1261 and thesecond tray 1240. In one embodiment, cold air may flow to the upper portion of thesecond tray 1240. If thetemperature sensor part 1260 is disposed among theice making cells 1241, in the lower portion of thesecond tray 1240, an error in the measurement of a temperature may be made due to the cold air. In one embodiment, thefirst insulation material 1262 is disposed between thetemperature sensor 1261 and thesecond tray 1240, an error in the measurement of a temperature, caused due to cold air, may decrease. - The
second insulation material 1263 may be disposed under thetemperature sensor 1261. Since thesecond insulation material 1263 is additionally provided, thetemperature sensor 1261 may accurately measure a temperature of water or ice that is accommodated in thesecond tray 1240, in the state where the effect of external air is minimized. - The
guide 1264 may be disposed under thesecond insulation material 1263. Theguide 1264 may fix awire 1246 connecting to thetemperature sensor 1261. At this time, theguide 1264 may fix thewire 1246 in a way that the direction in which thewire 1246 is withdrawn is the direction of the rotation shaft of thesecond tray 1240. Thus, even if thesecond tray 1240 makes a movement such as a rotation and the like, the wire may be prevented from separating from thetemperature sensor 1261. - Referring to
FIG. 7 , thewire 1246 connecting to thetemperature sensor 1261 may be fixed in a way that the direction in which thewire 1246 is withdrawn by theguide 1264 of thetemperature sensor part 1260 is the direction of the rotation shaft of thesecond tray 1240. Additionally, thewire 1246 may be held by awire hook 1245 that is formed in the lower portion of the other end of thesecond tray 1240, and fixed secondarily. -
FIG. 10 is a plan view showing asecond tray 1240 of thesecond ice maker 1200 of therefrigerator 1 of one embodiment, andFIG. 11 is a bottom view showing thesecond tray 1240 of thesecond ice maker 1200 of therefrigerator 1 of one embodiment. - The
second tray 1240 comprises a plurality ofice making cells 1241. Theice making cells 1241 may be arranged in the form of a matrix. As described above, under the assumption that the lines in the shaft direction of therotation shaft 1242 are columns, thesecond tray 1240 may compriseice making cells 1241 that are arranged in odd numbers of columns. - The
sensor accommodation part 1244 in which thetemperature sensor part 1260 is mounted may be disposed amongice making cells 1241 in the middle column, among odd numbers of columns. - As described above, the
sensor accommodation part 1244 may be disposed closer to the other end of thesecond tray 1240, which is farthest from the position into which cold air flows, than to one end of thesecond tray 1240, which is closest to the position into which cold air flows. A distance between thesensor accommodation part 1244 and one end of thesecond tray 1240, which is closest to the position into which cold air flows, may account for 60 to 90 % of a distance between one end of thesecond tray 1240, which is closest to the position into which cold air flows, and the other end of thesecond tray 1240, which is farthest from the position into which cold air flows. Preferably, a distance between thesensor accommodation part 1244 and one end of thesecond tray 1240, which is closest to the position into which cold air flows, may account for 70 % of a distance between one end of thesecond tray 1240, which is closest to the position into which cold air flows, and the other end of thesecond tray 1240, which is farthest from the position into which cold air flows, since the phase of water may change last in the position of thesensor accommodation part 1244, as described above. - The
sensor accommodation part 1244 may comprise a hook for fixing thetemperature sensor part 1260. The hook may be formed to protrude downward from the lower surface of thesecond tray 1240. Thetemperature sensor part 1260 may be press-fitted into and coupled to thesensor accommodation part 1244. - The
second tray 1240 may have a trayice removal stopper 1243, at one end thereof. The trayice removal stopper 1243 may be formed to protrude outward from one end of thesecond tray 1240. As thesecond tray 1240 is rotated by the iceremoval motor part 1250, the trayice removal stopper 1243 may contact a housingice removal stopper 1234. -
FIG. 12 is a view for describing thesecond ice maker 1200's operation of removing ice, in therefrigerator 1 of one embodiment. - The
rotation shaft 1242 of thesecond tray 1240 may be rotatably coupled to therotation hole 1233 of the secondice maker housing 1220. In this state, as the iceremoval motor part 1250 rotates thesecond tray 1240 with respect to therotation shaft 1242, at a predetermine angle, the trayice removal stopper 1234 of thesecond tray 1240 contacts the housingice removal stopper 1234 of the secondice maker housing 1220. As the iceremoval motor part 1250 rotates thesecond tray 1240 further in the state where the trayice removal stopper 1234 of thesecond tray 1240 contacts the housingice removal stopper 1234 of the secondice maker housing 1220, thesecond tray 1240 bends. As a result, ice accommodated in theice making cells 1241 of thesecond tray 1240 falls into the secondice maker housing 1220. - As described above, the
temperature sensor part 1260 is disposed between two ice making cells that are adjacent to each other, in the middle column ofice making cells 1241, among odd numbers of columns. The middle column, among odd numbers of columns, bends relatively slightly. Thus, despite the operation of removing ice, thetemperature sensor part 1260 may be stably fixed to thesecond tray 1240. - The embodiments are described above with reference to a number of illustrative embodiments thereof. However, embodiments are not limited to the embodiments and drawings set forth herein, and numerous other modifications and embodiments can be drawn by one skilled in the art within the technical scope of the disclosure. Further, the effects and predictable effects based on the configurations in the disclosure are to be included within the scope of the disclosure though not explicitly described in the description of the embodiments.
