Abstract

Alveolus for the manufacture of ice cubes characterized by being formed by a cylindrical cavity that starts from a tray, to which is anchored, a glass or alveolus also cylindrical, the walls of the lower cylindrical cavity being thickened in its part interior until reaching the same level surfaces, providing the resulting cube with a continuous exterior surface without protuberances.

Description

Socket for ice cube.

Currently the most common machines for  ice making consist of a rotary irrigation system on a tray in which slits are arranged as a small vessels, called alveoli, which will be filled with water to freeze by means of a jet of water vapor and form in this way the upper part of the ice cube.

The current ice cubes, resulting from the machine described above, are truncated and have the problem of not having a regular enough contour like to be able to fully adapt to the glass that will house it, commonly the so-called "tube" glass, cylindrical.

On the other hand, the current cube has half height of its outer wall, a notch that separates two parts, one upper narrower and lower one normally wider than the upper part. This is because the socket that has served as container for the formation of the cube consists of two pieces, one upper and one lower, welded together, this being welding always imperfect and leaving two parts of different diameter that give the cube the classic hat look.

With the improvement presented here the new cube, of  quasi-cylindrical shape and without appreciable size variations in its contour, couples with the tube glass in an almost perfect, just as a piston would fit inside a cylinder, avoiding bubbles and filling the maximum capacity of the glass that It houses it. This is due to the innovative anchoring of both parts of the alveolus as described below.

The new socket consists mainly of two parts, a lower one, which is the same slot in the tray that he holds it (Figure 3, A) and another superior that is properly the glass, usually of copper or other metal, that will form the part top of the cube (Figure 3, B).

They are attached by way of example and for better understanding of the exhibition Figures 1 to 3, being the Figures 1 and 2 the plant and the profile section of a tray machine for making cubes and figure number 3 a representation schematic of the new socket or cavity to house the ulna.

The section has been indicated in Figures 2 and 3 "A" relative to the slot in the tray that forms the part bottom of the hole that houses the socket and, as a section "B" the representation of the glass that tops the head, forming The top of the ice cube.

The tray, usually made of plastic, has one or several conical holes arranged downwards, in the which the socket is inserted.

The socket or vessel, usually metallic, has a  flange out on its top, which is inserted into the walls of the tray slit. This insertion is will normally perform by heat injection of plastic, leaving the upper flange of the socket inserted in the wall inside the tray hole.

This type of anchor makes the tray and the alveolus remain united, without such union being affected by sudden changes in temperature at which the machine will be submitted during ice making.

On the other hand, once inserted the socket to the walls of the hole, these will be given a greater thickness internal to avoid a difference on the cube in size between the part of the cylinder that forms inside the vessel metallic and that formed within the walls of the hole of the tray.

In this way, the inner surface of the walls of the cavity that will form the cube is completely smooth, given that the metal socket and the slit walls of the tray is at the same level, as shown in the Figure 3

Therefore, an ice cube is the result  perfectly cylindrical, with the advantages that this entails.

Claims (2)

1. Alveolus for the manufacture of ice cubes characterized by being formed by a cylindrical cavity that starts from a tray, to which it is anchored, a glass or cylindrical alveolus, being the walls of the lower cylindrical cavity thickened in its part inside until reaching the same level of surfaces, providing the resulting cube with a continuous outer surface without protuberances. 2. Socket for the preparation of ice cubes as in claim 1 characterized in that the anchoring system consists in that the lower part of the upper vessel has a flange or projection which is introduced to the walls of the lower hole by a system of plastic and metal insert injection with heat.
