Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a cooler having multiple ice-making chambers in a water circulation ice-making machine.

In general, a water circulation type ice maker has vertical and horizontal partition plates 1b and 1c on one side of a substrate 1a, as shown in FIG.
A large number of ice-making chambers 1d are arranged, and the substrate 1
a refrigerant circulation system 2 having a compressor 2a and a condenser 2b and connected to the refrigerant pipe 1e in the cooler 1; A water circulation system in which water is supplied from a water tray 3a arranged below the container 1 to a water sprinkling pipe 3c arranged above the cooler 1 by a pump 3b, and the water flows down from the water sprinkling pipe 3c toward the cooler 1. The system 3 is the main component, and the cooler 1
Ice is produced in the ice making compartment 1d (see Patent Publication No. 17449 of 1972). However, since the cooler 1 is manufactured by combining and joining a plurality of vertical partition plates 1b and horizontal partition plates 1c to one surface of the substrate 1a, and bonding the pipe 1e to the ground by soldering or the like, it is easy to manufacture. This process is extremely troublesome, unsuitable for mass production, high in cost, and has the drawback of easily causing variations in the finished state.

In view of this, the present invention has been proposed to provide a cooler having a large number of ice-making compartments on one side of the water-circulating ice-making machine by using an aluminum substrate and a bent refrigerant pipe bonded to the substrate and formed by extrusion molding of aluminum. The purpose of this is to significantly simplify manufacturing, achieve mass production and reduce costs, and to create a cooler with uniform finished product quality and extremely superior ice-making ability. .

To achieve this purpose, the cooler of the present invention has a structure in which a substrate made of an aluminum plate, a flat pipe bonded to one side of the substrate and formed by extrusion molding of aluminum are bent into a continuous wavy shape, and the wavy It is made up of a refrigerant pipe that is bent in a meandering manner so that the bent convex parts touch each other, and the bent concave parts of the refrigerant pipe define a large number of ice-making compartments, making it easy to manufacture. The objective is to improve cooling efficiency or ice-making capacity by defining the ice-making chamber with refrigerant pipes.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 2 and subsequent drawings.

2 to 4 show a cooler 10 in an ice making machine according to the present invention, and 11 is a substrate made of a rectangular flat aluminum plate whose peripheral edge is bent slightly upwardly. Substrate 11
An aluminum refrigerant pipe 12 is integrally joined to one surface (upper surface) by brazing or the like.

The refrigerant pipe 12 is made by bending a flat pipe 12a formed by extrusion molding of aluminum as shown in FIG. 12b, . . . and bent recesses 12c,
12c, . . . are formed alternately, and further, Fig. 3b
As shown in FIG.
A wavy flat pipe 12a is bent in a meandering manner to match the size range of the substrate 11 so that the pipes b, . . . are brought into contact with each other.

As shown in FIG.
A cooler 10 is constructed in which 3, . . . are defined.
The inside of the refrigerant pipe 12 (flat pipe 12a) is partitioned by a plurality of partitions (for example, five
It is divided into two aisles. Also, Figure 3b
Inside, reference numerals 14, 14 are connection pipes fixed to both ends of the refrigerant pipe 12, and are for connecting to the refrigerant circulation system of the ice maker.

Therefore, the cooler 10 having the above configuration is installed in an ice making machine as shown in FIG. When activated and water flows down from the upper water pipe toward the cooler, the water flows along the inner surface of each ice-making compartment 13 and freezes, forming ice cubes of a certain size in each ice-making compartment 13. is generated, and in that case, the cooler 1
0 is easy to manufacture because it is composed only of the substrate 11 and the flat pipe 12, and since the surface of the refrigerant pipe 12 forms the side surface of each ice making chamber 13, the refrigerant is not placed on the back surface of the substrate as in the past. Compared to coolers with glued pipes, they have better cooling efficiency and superior ice-making ability.

FIG. 5 shows another embodiment in which each ice making chamber 13' is formed into a cylindrical shape by increasing the bending radius (for example, 20 mm) when the flat pipe 12a is bent into a wave shape. In this case, the ice produced will not be pure ice cubes, but since the bending radius of the refrigerant pipe 12 is larger than in the previous embodiment,
This has the advantage that there is little risk of cracks occurring in the bent convex portions 12b, 12b, . . . when bent, and manufacturing becomes easier.

Incidentally, FIG. 6 shows a preferred example of use of the cooler according to the present invention in an ice making machine. In this example, the cooler 10 (or 10') is installed so as to be able to swing around a fulcrum 20. At the same time, by the drive device 21 provided on the back of the cooler,
It is constructed so that it can be swung from a position in which the opening face of the ice-making chamber is directed diagonally upward, as shown by a solid line, to a position in which the opening face is directed diagonally downward, as shown in imaginary lines, and by setting it to the former position when making ice, By sufficiently introducing water flowing down from the upper water sprinkler pipe 22 into each ice-making compartment, and by setting the latter position when ice is removed, the ice is removed from each ice-making compartment in a good manner. ing. here,
In this example, the conduit 23 in the refrigerant circulation system connected to the connecting pipe 14 at the end of the refrigerant pipe 12 is a flexible pipe so as not to hinder the swinging of the cooler. In addition, in the figure, 24 is a water tray, 25 is a water supply pump,
26 is a water pipe.

As explained above, in the ice maker cooler of the present invention, a flat pipe formed by extrusion molding of aluminum is bent into a continuous wave shape, and the bent convex portions of the wave shape are bent in a meandering manner so that the convex portions contact each other. A refrigerant pipe formed by the refrigerant pipe is joined to one surface of an aluminum substrate, and a large number of ice-making chambers are defined by the bent recesses of the refrigerant pipe, so it is easy to manufacture as a cooler in an ice-making machine. Therefore, it is suitable for mass production and can be manufactured at low cost, and has stable performance with no variation in product finish.Furthermore, since the entire circumference of the ice making chamber is formed by the surface of the refrigerant pipe, cooling efficiency is improved. This means that a cooler with excellent ice-making ability will be realized.In particular, in the present invention, the substrate and the refrigerant pipe are made of aluminum, which has excellent not only heat conductivity but also rust resistance. A cooler with excellent performance and high practical value can be obtained.
