On the other hand, the ice-making water sprinkler 10 has a fitting protrusion 10A that fits into the fitting groove 9D in the longitudinal direction of the central portion of the lower surface.
A pair of guide plates 10B and 10C are formed on both sides of the protrusion 10A, parallel to the protrusion 10A with an interval therebetween, and hanging downward from the protrusion 10A. A large number of water sprinkling holes 10E and 10F are formed at intervals in the longitudinal direction of the lower surface between 10C and communicate with the ice-making water channel 10D. Furthermore, a water supply port 10G communicating with the ice-making water flow path 10D is formed in the center of the side surface above the water sprinkling holes 10E and 10F.
communicates with the discharge side of a pump device (not shown) that circulates ice-making water. The ice-making water sprinkler 10 is supported on the de-icing water sprinkler 9 by inserting and fitting the fitting protrusion 10A into the fitting groove 9D, and the water sprinkler 10 of the ice-making water sprinkler 10 is connected to the water sprinkling hole 10E. , 10F is a deicing water sprinkler 9
It is positioned oppositely above the water guide surfaces 9B and 9C formed on the upper surface. At this time, the guide plate 10
B and 10C sandwich the cooling plates 2 and 3 by coming into contact with protrusions 2C and 3C protruding from the surfaces of the cooling plates 2 and 3,
These protrusions 2C, 3C keep the distance between the surfaces of the cooling plates 2, 3 and the guide plates 10B, 10C small, and the stopper 9H, which stands at the end of the upper surface of the deicing sprinkler 9 , This controls the insertion position of the ice-making water sprinkler 10 . Further, a guide member 11 is detachably provided at the lower part of the cooler 1 . The guide member 11 has a pair of insertion grooves 11A on both upper sides, which are inserted into the lower support flanges 2B and 3B, similar to the deicing water sprinkler 9 .

As shown in FIG. 5, which shows the relationship between the guide member 11 and the water receiving gutter 12, the guide member 11 has both sides slanted inward. Water guide surfaces 11B and 11C that guide frozen water to the water receiving gutter 12, and a large number of ice guide fins 11D that protrude outward from the guide surfaces 11B and 11C to guide only ice to the outside of the water receiving gutter 12. 11E, a water supply passage 11F for collecting the deicing water sprinkled on the back surfaces of the cooling plates 2 and 3 from the deicing water sprinkler 9 to the water receiving gutter 12, and ice guide fins at both ends and the center. A positioning plate 11G for the water receiving gutter 12 is formed below 11D and 11E. In the above configuration, the ice-making water that flows in from the water supply port 10G of the ice-making water sprinkler 10 passes through the ice-making water flow path 10D and is sprayed from each of the water sprinkling holes 10E and 10F, and the ice-making water that flows into the water supply port 10G of the ice-making water sprinkler 10 is sprayed from each of the water sprinkling holes 10E and 10F. The water falls onto the water guide surfaces 9B and 9C of the water sprinkler 9 , flows onto the surfaces of the cooling plates 2 and 3 that are continuous with the guide surfaces 9B and 9C, and hits the ice-making buttons 4 and 5 which are being cooled as the water flows down the surfaces. Gradually freezing, the unfrozen water flows from the lower edges of the cooling plates 2 and 3 along the water guide surfaces 11B and 11C of the guide member 11 and falls into the water receiving gutter 12, and this unfrozen water flows into the water storage tank ( (not shown) and then circulated again to the ice-making water sprinkler 10 , and the operation is repeated. When the prescribed ice-making operation is completed, lens-shaped ice 13 grows on the cooling plates 2 and 3 centering around the ice-making buttons 4 and 5, as shown by dotted lines in FIG.
In this state, the cooling operation and the ice-making water sprinkling operation are stopped, and the de-icing water is force-fed to the de-icing water sprinkler 9 , and the de-icing water is sprayed from each of the water sprinkling holes 9F and 9G via the de-icing water flow path 9E. Water flows onto the back surfaces of the cooling plates 2 and 3 facing the water spray holes 9F and 9G, and flows down the back surfaces. As a result, the temperatures of the cooling plates 2, 3 and the ice-making buttons 4, 5 are raised by the heat sensitivity of the deicing water, and the lenticular ice 13 is released from the ice-making buttons 4, 5. This ice 13 is guided to the outside of the water receiving gutter 12 by ice guide fins 11D and 11E, and falls into an ice storage (not shown). In addition,
The deicing water is collected into the water receiving gutter 12 through the water supply passage 11F of the guide member 11, returned to the water storage tank, and used as ice making water for the next cycle. (g) Effects of the invention As described above, the invention provides a pair of ice-making water guide surfaces on the top surface of the de-icing water sprinkler that are sloped low toward the upper edge of each cooling plate and are continuous with the surface of the cooling plate. At the same time, a fitting groove is formed on the top of the ice-making water sprinkler, and a fitting protrusion formed on the lower surface of the ice-making water sprinkler is fitted into the fitting groove. Since they are positioned facing each other upward, the ice-making water that has fallen onto the ice-making water guide surface is reliably flowed onto the surface of each cooling plate, resulting in stable ice-making operation. In addition, by fitting the fitting protrusion of the ice-making water sprinkler into the fitting groove of the ice-removing water sprinkler, the ice-making water sprinkler can be easily installed on top of the ice-making water sprinkler. Since the water sprinkler can be easily removed, the ice-making water guiding surface can be easily cleaned, and stable water flowing operation can be ensured.
