Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a down-flow ice maker, and particularly relates to a down-flow ice maker having a structure for guiding unfrozen water and ice to predetermined locations. It is something. (b) Conventional technology This type of conventional down-flow ice maker is, for example,
As disclosed in Publication No. 57-2866, a guide member is provided at the lower end of a pair of ice-making plates to guide excess ice-making water to a water receiving gutter, and approximately the center of this guide member is connected to the ice-making plate and the water receiving gutter. By bulging outward from the gutter, the guide member forms an outward upward guide surface that guides ice and water and an inward downward guide surface that guides only water. (c) Problems to be solved by the invention The above-mentioned prior art falling ice maker prevents the frozen layer from getting caught in the water receiving gutter by simply directing the frozen layer outward through the bulge. However, considering all ice falling conditions, it is not possible to completely solve the problem of ice getting caught in the water receiving gutter as long as the guide member and the water receiving gutter are spaced apart. In addition, since the upper guide surface of the guide member is for guiding ice and water, precision is required in the length and angle of this guide surface, and the position of the water receiving gutter, which is spaced apart below the guide member, is If it deviates, it causes various problems, such as being caught in the frozen layer. (d) Means for solving the problems In order to solve the problems of the conventional technology, the present invention provides a cooling system in which evaporation pipes are arranged inside a pair of cooling plates arranged approximately vertically, and In a flow-down ice maker that allows ice-making water to flow down to grow ice on each cooling plate, a water guide surface is formed at the bottom end of each cooling plate that slopes inward to guide unfrozen water to the water receiving gutter. A plurality of ice guide fins are provided at intervals on each water guide surface of the guide member to guide ice outward from the water receiving gutter. This constitutes a falling type ice maker in which the side surface is fitted with the edge of the ice guide fin. (E) Effect According to the above configuration, unfrozen water among the ice-making water flowing down the outer surface of each cooling plate is guided from the lower end of the ice-making plate to the water receiving gutter via the water guide surface of the guide member, and is also used for the deicing operation. Therefore, the ice detached from each cooling plate is guided to the outside of the water receiving gutter by the ice guide fins protruding from the water guide surface. Moreover, the guide fins also effectively act on the positioning of the water receiving gutter during the installation work of the water receiving gutter. (F) Embodiment Fig. 1 is a vertical cross-sectional view of the main part of the down-flow ice maker of the present invention, and Fig. 2 is a front view of the main part. 2 is composed of flowing water plates 1A, 2A and a number of ice making plates 1B, 2B which have better thermal conductivity than the flowing water plates 1A, 2A and are exposed substantially flush with the flowing water plates 1A, 2A. . A refrigerating system evaporation pipe 3 is disposed between the cooling plates 1 and 2 for heat exchange with the ice making plates 1B and 2B.
In addition, on the top of the cooling plates 1 and 2, there are running water plates 1A and 2A.
Water sprinkling ports 4A, 4 that allow ice-making water to flow on the outer surface of the
Ice-making water sprinkler 4 formed with B and water flow plates 1A and 2
Water sprinkling port 5A that allows deicing water to flow on the inner surface of A,
Water guide surfaces 7A and 5B are provided at the lower ends of the cooling plates 1 and 2, respectively, to incline inwardly and guide unfrozen water to the water receiving gutter 6. 7
A water guiding member 7 having a shape B is provided. A large number of ice guide fins 8 are protruded from the water guide surfaces 7A and 7B of the water guide member 7 at predetermined intervals, the upper portions of which are inclined outwardly and extend in the direction of flowing water. In addition, a passage 9 is formed in the water guiding member 7 for collecting deicing water sprinkled from the deicing water sprinkler 5 into the water receiving gutter 6. Therefore, the water receiving gutter 6 has an ice guide fin 8 on its inner surface.
The position is determined by fitting the edge of the In the above configuration, the ice-making water that is force-fed to the ice-making water sprinkler 4 by the circulation pump 10 is supplied to the water sprinkling port 4.
The ice flows down from A and 4B to the water plates 1A and 2A, and gradually freezes onto the ice-making plates 1B and 2B, which are being cooled at this time. The unfrozen water is guided to the water receiving gutter 6 via the water guide surfaces 7A and 7B of the water guide member 7, and is circulated to the water sprinkler 4 again. When the prescribed ice-making operation is completed , lens-shaped ice 11 grows on the ice-making plates 1B and 2B of the cooling plates 1 and 2 as shown by the dotted lines, and in this state, the water sprinkling operation on the cooling plates 1 and 2 is started. Then, the cooling operation is stopped, and the deicing water is force-fed to the deicing water sprinkler 5, and is made to flow down from the water sprinkling ports 5A, 5B onto the inner surfaces of the water flow plates 1A, 2A. As a result, the temperature of the cooling plates 1 and 2 is raised by the heat sensitivity of the deicing water, and the ice 11 is removed from the ice making plates 1B and 2B. This ice 11 is guided to the outside of the water receiving gutter 6 by the ice guide fins 8, and falls into the ice storage (not shown). In addition, in the present invention, the cooling plates 1 and 2 are replaced by the flowing water plates 1A and 2.
The present invention is not limited to the configuration consisting of the ice making plates 1B and 2B, and the design can be changed without departing from the gist of the present invention. (g) Effects of the invention As described above, the present invention ensures that unfrozen water is guided into the water receiving gutter via the water guide surface of the water guide plate without detouring to the position where it is removed from the water receiving gutter. The ice guide fin can reliably guide only ice to the outside of the water receiving gutter. Further, since the water receiving gutter is fitted to the ice guide fin, the position of the water receiving gutter can be accurately determined, and it is also possible to prevent ice from getting caught between the ice guiding fin and the water receiving gutter.
