Description

[Detailed explanation of the invention] (a) Industrial application field The present invention has a cooling plate that guides unfrozen water to a water receiving gutter and releases it from the bottom end of a pair of cooling plates arranged substantially vertically with a gap between them. The present invention relates to an improvement of a down-flow ice maker equipped with a guide member for guiding ice to the outside of a water receiving gutter. (b) Conventional technology This type of conventional down-flow ice maker is, for example,
As disclosed in Japanese Patent No. 54-182961, a freezing system evaporator is disposed on one side of a vertically arranged ice-making plate, and ice-making water is allowed to flow down on the other side to grow a frozen layer. In the ice making machine, a water receiving container is provided below the ice making plate, and the open end of the water receiving container is located outward from the ice making surface of the ice making plate, and the open end of the water receiving container is placed below the ice making plate during deicing. It has a plurality of protruding vertical ribs to guide the ice blocks further outward. (c) Problems to be solved by the invention Since the above-mentioned prior art falling type ice making machine has vertical ribs protruding from the ice making plate, there is a great possibility that the frozen layer on the ice making plate will grow and reach the vertical ribs. This poses various problems, such as the vertical ribs becoming a hindrance to the ice removal operation and the fact that it is very difficult to make the ribs protrude from the ice-making plate. (d) Means for solving the problem The present invention has a pair of cooling plates disposed substantially vertically with a gap between them, at the lower ends of which guide unfrozen water to a water receiving gutter and receive detached ice. In a falling type ice maker equipped with a guide member that guides outward from a water gutter, the lower ends of the cooling plates are each bent inward to form a support flange, and the guide members are attached to support flanges on both sides, respectively. an insertion groove that is inserted to support the guide member; a pair of water guide surfaces that are continuous with the lower edges of the respective cooling plates and slope inward in the inserted state, and whose lower ends face the water receiving gutter;
The above-mentioned problems of the prior art are solved by forming the ice guide fins into a resin having a large number of ice guide fins that protrude at intervals from each water guide surface and whose upper edges are sloped outwardly. It is a down flow ice maker. (E) Effect According to the above configuration, the guide member can be easily attached to the lower part of the cooler by inserting the insertion grooves formed on both sides of the guide member into the lower support flange of the cooling plate. Moreover, since the guide member, which has a water guide surface continuous with the lower edge of the cooling plate and a large number of ice guide fins protruding from the guide surface, is made of resin, freezing on the guide member is reliably prevented. The water guiding surface guides unfrozen water into the water receiving gutter, and the ice guiding fins guide breakaway ice outwardly of the water receiving gutter. (f) Examples Examples of the present invention will be described below based on the drawings. Fig. 1 is an exploded perspective view of the main parts of the down-flow ice maker of the present invention, Fig. 2 is a front view of the main parts, Fig. 3 is a sectional view taken along line A-A in Fig. 2, and Fig. 4 is a cross-sectional view of the main parts in Fig. 3.

A pair of insertion grooves 9A are formed to be inserted into the
It is supported at the lower part of the cooler 1 by inserting the guide member 9 from the lower insertion opening 8 and inserting and fitting the insertion groove 9A into the lower support flanges 2B and 3B, and both sides of the lower part of the insertion groove 9A A water receiving gutter 1 whose surfaces are inclined inward and are continuous with the lower edges of the surfaces of the respective cooling plates 2 and 3, and whose lower ends communicate with a water storage tank (not shown).
By forming a pair of water guide surfaces 9B and 9C that face the water guide surfaces 9B and 9C and protruding from the guide surfaces 9B and 9C with a gap between them, and by sloping the upper edge outwardly, only ice can be transferred to the water receiving gutter 10. A large number of ice guide fins 9 guide the ice outward.
D, 9E, and a water supply passage 9 for collecting the deicing water sprinkled on the back surfaces of the cooling plates 2 and 3 into the water receiving gutter 10.
F, and ice guide fins 9 at both ends and the center.
The guide member 9 having the positioning plate 9G of the water receiving gutter 10 on the lower side of the guide member D and 9E is formed by integrally molding these parts from synthetic resin. Additionally, an ice-making water sprinkler 11 is provided at the top of the cooler 1 to flow ice-making water onto the surfaces of the cooling plates 2 and 3.
A deicing water sprinkler 12 for flowing deicing water onto the back surfaces of the cooling plates 2 and 3 is removably provided, and the deicing water sprinkler 11 is inserted from the upper insertion opening 7. A pair of ice-making water guide surfaces 12A, 12B supported by the upper support flanges 2A, 3A, and a pair of ice-making water guide surfaces 12A, 12B on the upper surface that are sloped low toward the upper edges of the surfaces of the cooling plates 2, 3 and continuous with the surfaces of the cooling plates 2, 3; Sprinkle holes 12C and 12D are formed in the cooling plates 2 and 3, respectively, so as to face the back surfaces of the cooling plates 2 and 3. On the other hand, the ice-making water sprinkler 11 is fitted and mounted on the upper part of the de-icing water sprinkler 12, and has a water sprinkling hole 11A on the lower surface facing the ice-making water guide surfaces 12A, 12B formed on the upper surface of the de-icing water sprinkler 12. 11B is formed, and a water supply port 11C formed at the center of the side surface communicates with the discharge side of a pump device (not shown) that circulates ice-making water. In the above configuration, the ice-making water flowing from the water supply port 11C of the ice-making water sprinkler 11 flows through each water sprinkling hole 11.
Water is sprinkled from A and 11B to the ice-making water guide surface 12
Ice-making buttons 4, 5 fall onto the surfaces of the cooling plates 2, 3 that are continuous with the guide surfaces 12A, 12B, and are cooled as they flow down the surfaces.
The unfrozen water gradually freezes on cooling plates 2 and 3.
