DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direct cooling type refrigerator having a function of turning water in an ice tray by a cooler into ice.

[0002]

2. Description of the Related Art As a conventional ice making method of a direct cooling type refrigerator, a cooling pipe 3 is formed by a flat metal plate 2 and an adhesive aluminum tape 4.
The cooling temperature was transmitted to the freezer compartment by fixing the one that was sandwiched and attached and fixed to the back of the inner box 1 with double-sided tape, and the water in the ice tray set on the bottom of the freezer compartment was frozen. .

[0003]

However, in the above-mentioned conventional structure, the cooling pipe 3 is set on a flat metal plate 2 and an adhesive aluminum tape 4 is attached thereon, thereby lowering the temperature of the cooling pipe 3 in the freezer compartment. To freeze the water in the ice tray 6 set on the inner box 1, but the air layer is used to adhere the adhesive aluminum tape 4 to the cooling pipe 3 and the flat metal plate 2. There is a disadvantage that a large space is generated, cooling performance is reduced, and workability is poor.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a direct-cooled refrigerator-freezer that can improve the cooling performance and guarantee stable cooling performance.

[0005]

In order to achieve this object, the present invention uses a curved metal plate 5 and a flat metal plate 5 having a fixing means 8 such as an adhesive or a double-sided tape on its surface. The cooling tube 3 is sandwiched between the metal plates 2 and fixed to the bottom surface of the inner box 1 of the freezing room to reduce the space formed by the air layer near the cooling tube and efficiently transmit the cooling temperature to the freezing room. The cooling performance is improved.

As a result, the space formed by the air layer near the cooling pipe 3 is reduced, so that not only the cooling performance is stabilized, but also the workability is improved, and stable quality can be guaranteed.

As a specific means for solving these problems, in claim 1, a space near the cooling pipe is reduced by sandwiching a cooling pipe for cooling the ice tray between two metal plates, and the plate is placed in an inner box. Improve the ice making function by fixing.

[0008] In the second aspect, an ice making function is improved by fixing a cooling tube sandwiched between two metal plates inside or outside the storage of the inner box.

According to a third aspect of the present invention, the cooling pipe is sandwiched between a flat metal plate and a curved metal plate.
Alternatively, the ice making function is improved by employing the ice tray cooling method of the direct cooling type refrigerator according to the second aspect.

According to a fourth aspect of the present invention, when the cooling pipe is sandwiched between two metal plates, the cooling tube is sandwiched and fixed by having a fixing means such as an adhesive or a double-sided tape on one of the two metal plates. The ice making function of the direct cooling type freezer refrigerator according to any one of claims 1 to 3 is improved by the ice making function.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the method for cooling an ice tray of a direct cooling type refrigerator according to the present invention, when the cooling tube is installed outside the inner box storage of the freezing room, the bottom of the inner box of the freezing room is formed into a flat surface, and the back surface is formed. A flat metal plate is evenly stuck with double-sided tape or adhesive, a cooling tube is set on top of it, and a double-sided tape is stuck on top of it, or curved with adhesive applied It is sandwiched and fixed by a metal plate.

When the cooling tube is installed inside the inner compartment of the freezer compartment, the bottom of the inner compartment of the freezer compartment is formed into a curved shape, and a curved metal plate is uniformly formed on the inner surface with a double-sided tape or an adhesive. Then, a cooling pipe is set from above, and a double-sided tape is pasted on the cooling pipe from above, and sandwiched and fixed by a flat metal plate to which an adhesive has been applied.

Since the cooling pipe is sandwiched between the flat and curved metal plates from both sides, the contact area between the cooling pipe and the metal plate is increased, and the transmission of the cooling pipe temperature to the metal plate is enhanced. When the cooling pipe is outside the inner box storage, the cooled flat metal plate is evenly stuck to the back of the bottom of the inner box of the freezer with double-sided tape, and the cooling pipe is placed inside the inner box storage. In this case, the cooling temperature can be efficiently transmitted to the inside of the freezer compartment or to the ice tray by the direct contact of the flat metal plate with the ice tray in the refrigerator. Ice is efficiently made by placing an ice tray containing water on the surface of the inner box to which the flat metal plate is attached.

When the cooling pipe is outside the inner box storage, an adhesive tape or urethane foam with glue is attached to both end surfaces of the curved metal plate to prevent the heat insulating material from entering from outside. The cooling temperature can be transmitted efficiently.

As the metal plate, a metal having high thermal conductivity such as aluminum, copper and iron is used.

In the case of sticking and fixing using an adhesive, an adhesive having high thermal conductivity is preferable.

When a double-sided tape is applied to the curved metal plate used here, it is easy to use a metal plate to which the double-sided tape has been applied in a flat state before being processed into a wavy shape by pressing. .
