Abstract

PURPOSE: To make a regular triangular prism ice block and to separate the ice block while conforming to gravitation by arranging a regular triangular prism ice making plate dispersed with recesses such that each recess projects vertically upward, fixing a cooling tube on the outer circumferential wall of each recess and disposing a fountain unit between recesses on the underside thereof. CONSTITUTION: An ice making plate 11 for making a plurality of regular triangular prism ice blocks simultaneously is arranged such that each recess 13 thereof having a side of about 30 mm projects vertically upward and a cooling tube 4 is fixed at a position of one third of the height of outer circumferential wall. A fountain unit 12 is provided, at a position between recesses 13, 13 facing the rear inner wall thereof below the recess, with a nozzle 14 coupled with the forward end of an original water pipe 10 for ice. Three inclining wall faces at the recess 13 are cooled down to a uniform temperature by the cooling tube 4, water is sprayed uniformly, and the recess 13 is filled with an ice thus making an ice having flat bottom. Since hot gas flows from a compressor 1 through an ice separation bypath circuit 6 into the cooling tube 4, ice block is separated easily to drop smoothly into an ice receiving tank and deposited therein.

実の単体である氷塊が生成される。(Function) It is an ice block in the shape of a regular triangular pyramid, and all three sides except the bottom are slopes with widening skirts, so the ice layer forms concave areas Q"ll and α
When growing along the inner wall of the beauty, by following the growth process in which the space is closed from the top at the back and successively reaches the bottom, when the ice layer of depressions 0■ and 0■ is formed, there will be no depression or nest. Since there is no such thing, the bottom surface of the triangle is smooth, and
As a result of becoming independent and not connected to its surroundings, a transparent, solid, single block of ice is generated.

また、離氷の際は、裾拡がりの３斜面を持つ形状である

In addition, there is a cooling tube-shaped ice making plate 0υ which has a structure of two plates mated together and grooves for refrigerant circulation are formed at predetermined locations on the mating plate on the outside of the concave portion 03). It's okay.

73 and parallel to the base, the generated ice block is of an appropriate size to be thrown into a cold drink, and as described later, the solid ice block is in the shape of an equilateral triangular pyramid or close to it. The structure is such that it can be obtained.

次いで製氷運転の態様を説明する。Next, the mode of ice-making operation will be explained.

ノズルａ旬、α０からは水用原水が噴水し凹部Ｏｍ、α
ｍの内周壁に均散布される。The concave portions α and α of the ice making plate OD are cooled to a low temperature that allows ice to be made by the cooling pipes (4), while raw water for water is sprayed from the nozzles a and α0 of the fountain device (2), and the concave portion Om ,α
It is evenly distributed on the inner circumferential wall of m.

この散布原水は、内周壁の頂部から斜面を伝って流下し
、この流下の間に次第に氷結してゆき、氷結しない原水

される。This sprayed raw water flows down the slope from the top of the inner peripheral wall, and gradually freezes during this flow, and the unfrozen raw water drips downward and is collected in the water tank (8) and reused. .

凹部０りにおける３つの斜壁面は冷却管（４）によって
前面略々均一な温度に冷却される結果、散水が均一に成

同じ厚さの氷層が成長してくる。As a result, the three sloped wall surfaces in the recessed portion are cooled to a substantially uniform temperature on the front surface by the cooling pipe (4), and as a result, water is uniformly sprinkled on each sloped wall surface in order from the top, and
An ice layer of the same thickness grows.

かくして頂部から凹部αｍ内空間は氷によって充填され
てゆき、第３図に示す如く、底面が平坦な状態となって
完全充填された氷結が行われる。In this way, the space inside the recess .alpha.m is filled with ice from the top, and as shown in FIG. 3, the bottom surface becomes flat and completely filled with ice.

With this detection signal, the condenser (2) fan and water pump (9)
The ice removal solenoid valve (7) is opened to shift to ice removal operation.

下し図示しない受水槽内に堆積する。The hot gas leaving the compressor (1) passes through the de-icing bypass circuit (6) and flows into the cooling pipe (4), thereby increasing the temperature of each wall of the recesses α and 0 of the ice making plate α. As a result, the ice blocks adhering between the walls break off as the adhering surfaces melt, and because the slope is wide at the base, they fall smoothly and are deposited in a water receiving tank (not shown).

が好ましい形態であることを意味している。As mentioned above, various experiments were carried out in the case of specifying the dimensions of the concave part α and the installation position of the cooling pipe (4). As shown in FIG. Ice is formed that resembles a regular tetrahedron (tetrahedron), and this is due to the fact that the bottom surface is a smooth plane. In this case, as shown in Fig. 4, there is a depression in the center of the bottom, and ice swells and protrudes around the opening of the depression a1, making it difficult to obtain ice cubes with a normal shape.
- the side is smaller than 30 mm or the cooling pipe (4) is 17 mm
If the ice cube is installed at a higher position than 3, as shown in FIG. 5, it is easy to form an ice block with a fairly deep depression in the center of the bottom, so the configuration of the above-mentioned embodiment is preferable. It means something.
