Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an ice-making device, and in particular, cooling pipes are attached to a plurality of ice-making chambers provided in a frame tray, and ice-making water is supplied to the ice-making chambers. This invention relates to an ice making device that supplies and grows ice cubes.

[Prior art] Conventionally, as this type of device,
There is something disclosed in the No.
To explain the figures and FIG. 3, the entire ice making chamber 1 made of copper is tin-plated for rust prevention, a plurality of ice making chambers 1 are fitted into a frame tray 2 made of resin, and the frame tray 2 is soaked with water. The cooling pipe 3 was fixed to the outer surface of the ice making chamber 1 by brazing while cooling.

Ice cubes are grown in the ice making compartment 1 by sprinkling ice making water from a sprinkler pipe into such an ice making device and cooling the ice making compartment 1 by passing a refrigerant through the cooling pipe 3. 5 is a water supply pipe for deicing.

[Problems to be solved by the invention] In the conventional ice making device as described above, in order to secure the cooling pipe 3 to the ice making chamber 1, brazing was performed while cooling the resin frame plate with water. However, there were problems in that the workability was extremely poor and the cost was high.

In addition, there is a step 2a at the joint between the ice making chamber 1 and the frame tray 2.
As a result, the ice grows from the ice making chamber 1 to the wall of the frame tray 2, and steps are formed on all four sides of the produced ice, resulting in the problem of spoiling the beauty of the ice.

This idea was made to solve the above problems, and the device can be manufactured easily and inexpensively.
Another object of the present invention is to obtain an ice making device that can grow ice in a good shape.

[Means for solving the problem] The ice making device according to this invention has a frame tray and an ice making chamber integrally formed using a metal plate with relatively low thermal conductivity, and a metal plate with high thermal conductivity on the outer peripheral surface of the ice making chamber. Apply a metal plating layer to secure the cooling pipe to the ice maker.

[Function] In this invention, when brazing the cooling pipe to the ice-making compartment, there is no need to cool the frame tray, and since the frame tray is made only of metal with low thermal conductivity, it is possible to prevent ice from entering the frame tray. Growth is suppressed and there are no steps on the circumferential surface of the produced ice.

[Embodiment] Fig. 1 shows an embodiment of this invention, and in the figure, a plurality of rectangular parallelepiped ice making chambers 1 are placed in a frame tray 12 made of a thin metal plate such as stainless steel with low thermal conductivity.
1 is integrally formed. Then, a thick plating layer 11a of a metal such as tin is applied to the outer peripheral surface of the ice making chamber 11. This plating layer 11a is applied only to the outer peripheral surface of the ice making chamber 11, excluding the wall surface rising 5 to 8 mm from the opening end of the ice making chamber 11 and the frame tray 12.
Do not perform plating on the part. Next, the cooling pipe 3 is fixed to the outer circumferential surface of the ice-making chamber 11 through the plating layer 11a by brazing or the like.

With the above configuration, when ice-making water is sprinkled from the sprinkler pipe 4 into the ice-making compartment 11 and the refrigerant is circulated through the cooling pipe 3 to cool the ice-making compartment 11,
Heat in the ice making compartment 11 is absorbed by the cooling pipe 3 through the plating layer 11a with good thermal conductivity, the entire ice making compartment 11 is cooled uniformly, and ice grows in the ice making compartment 11.
On the other hand, since the frame plate 12 is made of only a thin metal plate with poor thermal conductivity, the growth of ice on the frame plate 12 is suppressed. In this way, the desired regular hexahedral ice cubes can be manufactured.

Next, in the water removal process, water is supplied from the water supply pipe 5 to the frame tray 12, and this deicing water flows in contact with the outer peripheral surface of each ice making chamber 11, melts the ice that has grown on the frame tray 12, and flows into the overflow pipe 6. Flow into. At the same time, hot gas is circulated through the cooling pipe 3,
The entire ice making compartment 11 is heated to remove ice.

The ice making and deicing processes described above are performed by a well-known fully automatic ice making machine.

[Effects of the invention] As is clear from the above explanation, this invention has the following effects:
Since the frame tray 12 and the ice making chamber 11 are integrally formed,
Since it is easy to process and has good workability, it can be made at a low price, and since there is no step between the frame tray 12 and the ice making chamber 11, there are effects such as not spoiling the beauty of the ice.

Furthermore, the plating layer 11a made of metal with good thermal conductivity also has the effect of suitably maintaining ice-making ability.
