Description

DETAILED DESCRIPTION OF THE INVENTION This invention has a plurality of electric circuits in am of the plate member, and
IIvc is made by extruding a metal plate member having a number of lattice-like partition plates on one side parallel to the pipes, and applying mold threads to the pipes of this plate member to meander the pipes. At the same time, the other lattice-shaped partition plate is provided at a substantially right angle to the lattice-shaped partition plate 173 of the tray member and brazed to the plate member [4H1].

In the conventional ice tray manufacturing method, as shown in FIG.
2 is provided, and cutouts 24t are provided at 1fBK-foot intervals below the other lattice-like partition plate 23, and 10,000 partitions &21
and the other partition plate 23 are assembled in a lattice shape, intersecting each other at approximately right angles, and brazed.

After brazing 1III 25 on each of the four sides, placing the grid-like partition plates 21 and 25 on the bottom plate 26 and brazing them, and then bending the long pipe and placing the meandering pipe 27 under the bottom plate 26. Ice trays are made by soldering the other side.

In this conventional ice tray manufacturing method, a grid-like partition plate 21
．． 23 to the bottom plate 26, or meandering pipe 2.
Since there are many soldered parts such as soldering 7 to the bottom plate 26, there is a drawback that the defect rate of the product as an ice tray increases accordingly. History of traditional ice cube trays! The disadvantage of the 11 construction method is that many parts are brazed, which worsens heat exchange symptoms.

To this @! In view of these shortcomings of Ati's conventional method of manufacturing ice trays, we decided to reduce the number of parts used to make ice trays as much as possible, thereby reducing the defective rate of ice trays and improving heat exchange performance. Its purpose is to make it easier to crawl through ice cube trays.

Next, the method for manufacturing the ice tray of this invention is illustrated with drawings.
Explain.

I! do. This dish member 1 has four vertical conduits 2 at regular intervals on the bottom, and five vertical partition plates 3 at regular intervals on the top.

A large hole 4 is drilled into the conduit 2 at a predetermined position on the bottom of the front and rear ends of the dish member 10, and the Mk
Braze the U pend 5 which is the connecting pipe.

Detailing the 1m 11th order of U-bend 5, the 1st and 2nd from the left side at the # end of IIkIfi of plate member 1.
A U-bend 5t is provided for the blind pipe 2.2 and the 6th and 4th f-paths 2゜2, respectively, and in the wave analysis, the 2nd and 6th pipes 2, 2 [U bend 5] are installed from the left side. and solder.

A large number of notches 6 are provided in the horizontal direction at regular intervals t in the vertical partition plate 3 of the plate member 1, and the horizontal partition plates 7 are respectively fitted into the notches 6 and assembled into a lattice shape by brazing. do. Then, side plates 8 having a wider width than the horizontal cutting plate 7 are brazed to the front and rear ends of the tray member 1, and the pipe line 2 at the front and rear ends is sealed with the side plates 8 to produce an ice-making tray 9 in a virtual state.

Example 2 An aluminum alloy plate member 11 is extruded into one piece. This dish member 11 has four vertical conduits 12 at regular intervals on the bottom, and five vertical partitions &13 at regular intervals on the top.

On the 111th surface of the front and rear ends of this plate member 11, the first and second snow roads 12, 12 and 5 are located from the left side at the front end.
The main and fourth pipes 12 and 12 are each soldered with U-shaped honsuki pipe A, and at the end, the second and fifth pipes 12 and 12 from the left side are brazed with a U-shaped I [pipe 15]. Attach.

In the horizontal partition plate 17, notches 16 are provided at five locations in the center of the partition plate 17 in the vertical direction at the same intervals as the vertical partition plate 15 and in the shape of the partition plate 17. The notches 1i16 of the horizontal partition plates 17 are respectively fitted into the vertical partition plates 15 of the plate member 11, and assembled into a lattice shape and brazed. Then, a side plate 18 is brazed to the # rear m portion of the tray member 1 to produce an ice tray 19.

Ice is made by filling the ice trays 9 and 19 made by the method of Example 1.2 with water and passing a refrigerant through the meandering pipes 2 and 12 to cool the ice trays 9 and 19.

When making ice, the tray member consisting of the pipes 2 and 12 of the T/Clll ice tray, the bottom plate, and one partition plate 3.15 is made of metal, so it is faster than the refrigerant in pipes 2 and 12. Ice can be formed quickly by allowing cold air to flow through the ice.

After making water in an ice tray, a portion of the ice Wj deposited on the ice tray is bathed through pipe 2.12Y-heating medium, and the ice is taken out from the ice tray.

This ice tray should be used when giving out ice money, especially when it comes to squirting 5iii
If the tip m of the partition plate is made sharp and inclined in a tapered shape as in Example 1, it becomes easier to take out the ice from the ice cube tray.

In addition, in implementation example 1.2, there is a notch S on one side of both partition plates.
Although the explanation has been given on a case where a cutout portion having approximately half the width is provided on both partition plates, it is of course possible to provide a cutout portion with approximately half the width.

As a next joining method, r! Brazing the exact example is outside the method vC
There are @ statues and adhesion using adhesives.

In the method for manufacturing an ice tray of this invention, the tray member consisting of the conduit, the bottom plate, and 10,000 partition plates is extruded into one piece, so compared to the ice tray made by the conventional method, the brazing of the ice tray is easier.
6I! Since the amount of 9r is small, ice trays can be manufactured easily, and the defective rate of ice trays due to KCI attachment can be reduced.

Furthermore, the method for manufacturing the ice tray of this invention is as shown in # [Since the ice tray is manufactured using an integrated tray member, the heat exchange performance of the ice tray is better than the conventional one in which each S is individually brazed. Therefore, the ice making capacity per hour can be increased.
