る。Next, based on the above configuration, the operation of the present invention will be explained from the time when ice making is completed. When the circulation pump 13 stops and the ice-making operation ends, high-temperature refrigerant gas is circulated through the evaporation tube 3 to heat the cooler 4, and a dehydration operation of the ice frozen in each small chamber 2 is started. At the same time, the water supply valve 18 is opened and water is sprayed from the sprinkler 14 onto the surface of the water tray 5 between the cooler 4 and the rear guide wall 8. By flowing this water over the top plate 5A of the water tray 5 between the cooler 4 and the side guide walls 9 and 10, the ice that was firmly attached to the top plate 5A of the water tray 5 at the end of ice making is removed. The close contact between the lower surface and the upper surface plate 5A of the water tray 5 is relaxed. Also, a part of the sprinkled water is returned to the water tank 11 through the large and small auxiliary return holes 16.17, so each guide wall 8.9.1
Overflow from 0 is prevented. Moreover, due to the action of the large auxiliary return hole 16 formed on the upstream side of the water tray 5, the water tray 5
Each guide wall 8
．． In addition to more reliably preventing water from overflowing from 9.10, water can flow uniformly over the top surface of the water tray 5 around the cooler 4, and the close contact between the ice and the top plate 5A of the water tray 5 is more effectively alleviated. Ru.
この様な密着緩和によって、水皿５を氷から剥離すると
きに掛かる駆動装置１５の負荷を軽減することができる
のである。而して、水皿５は第２図の二点鎖線で示すよ
うに、各小室２を開放した傾斜位置まで駆動装置１５に
よって傾動せしめられる。By relaxing the adhesion in this way, it is possible to reduce the load on the drive device 15 when peeling the water tray 5 from the ice. The water tray 5 is then tilted by the drive device 15 to an inclined position in which each small chamber 2 is opened, as shown by the two-dot chain line in FIG.

る。従って、本発明は製氷終了と同時に、水皿５の表面
に散水するものに限定されない。Thereafter, when the ice leaves the cooler 4, the water tray 5 is moved back by the drive device 1 to a horizontal position that closes each of the small chambers 2, as shown by the solid line in FIG. In this state,
The water sprinkled from the water sprinkler 14 onto the surface of the water tray 5 is
Since there is no ice on the front end of the top plate 5A and the cooler 4, it enters through the gap between the cooler 4 and the top plate 5A of the water tray 5, and the ice enters the return hole 7.
Water is supplied to the water tank 11 through. In this case as well, the large and small auxiliary return holes 16 and 17 function effectively as a measure to prevent flooding. Therefore, the present invention is not limited to spraying water on the surface of the water tray 5 at the same time as ice making is completed.

Since water is sprinkled on the upstream side of the water tray, the water level in the upstream section tends to be high, but since the auxiliary return hole is formed larger on the upstream side than on the downstream side of the water tray, the water level in the upstream section tends to be higher. It is possible to suppress the rise in water level and reliably prevent water from overflowing from the guide wall.
