Abstract

PROBLEM TO BE SOLVED: To raise the ice-making capacity and downsize the refrigerator, by providing one part of the cooler with a recess where a cooling pipe exclusively used for ice making is arranged, and accommodating an ice making pan, and bringing the cooler close to the ceiling of an inner box. SOLUTION: A cooler 23 which is L-shaped and has a recess 22 at its one part is attached, with its inner side to an inner box, being caught on the hook projected from an electrical equipment box 20 attached to the upper right of the inner box 3. In the cooler 23, a cooling pipe 23 to allow a refrigerant to pass is arranged, and in the recess 22, a cooling pipe 13 is arranged directly for concentration from an inlet pipe 24. The cooling pipe 13 passes the remaining face after passage of the recess 22, and goes to an outlet pipe 25, and the refrigerant is returned after compression. Moreover, since an ice making pan 19 is accommodated, with the recess 22 of the cooler 23 as an exclusive place, a refrigerator stable in ice making capacity is made. Moreover, since the cooler 23 can also be brought close to the ceiling of the inner box 3, the downsizing of the refrigerator becomes possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a cooler for cooling the inside of a refrigerator.

[0002]

2. Description of the Related Art A conventional refrigerator cooler is disclosed in Japanese Utility Model Application Publication No. 63-90769. In direct-cooled small refrigerators, too, the miniaturization of coolers and the installation of coolers on the top surface are being promoted in order to improve the storage capacity of cans.

Hereinafter, a conventional example will be described with reference to FIGS. 1 is a refrigerator main body, 2 is an outer box, 3 is an inner box, 4 is a foamed polyurethane insulating material filled between the outer box 2 and the inner box 3, 5 is a refrigerator room, and an upper right corner of the inner box 3,
An electrical component box 8 that accommodates a board 7 that controls the operation and defrosting of the compressor 6 is attached.

The L-shaped cooler 1 is hooked on the hook 9 projecting from the electrical component box 8 and attached to the inner box 3.
In the lower part of the cooler 10, a shelf 12 that slides on a rail 11 of the inner box 3 is installed.

[0005] The cooler 10 has a cooling pipe 13 through which a refrigerant passes, and the refrigerant heated and pressurized by the compressor 6 is supplied to a condenser 14.
, The temperature decreases and expands in the cooler 10 tube 13, and the cooler 1
0 is cooled. The expanded refrigerant returns to the compressor 6 through the return pipe and repeats. Numeral 15 denotes a frost receiving tray provided on the shelf 12 in the refrigerator, and a lower portion of the cooler 10 for receiving defrost water which has defrosted the frost attached to the cooler 10. The defrost water received by the frost receiving tray 15 is discharged to the outside by a connection pipe 16 and is evaporated after being stored in an evaporating tray 17. Reference numeral 18 denotes an ice tray placed on the cooler 10.

In such a configuration, the cold air exchanged in the cooler 10 cools the food cans stored in the shelf 12 by natural convection. Due to the circulation of cool air, frost is formed on the cooler 10 one after another.

After a certain period of time, the cooling operation is stopped by the substrate 7 provided in the electrical component box 8, the defrosting water generated by thawing the frost is received by the frost tray 15, and a part thereof is naturally evaporated.
Discharge. The ice making of the ice tray 18 is repeatedly performed at a low temperature on the surface of the L-shaped cooler 10.

[0008]

However, in the above configuration, the cooling effect of the cooler 10 varies depending on the location depending on the flow direction of the refrigerant in the cooler 10 and the shape and position of the cooling pipe 13.

The ice tray 18 has a drawback that the position of the ice tray 18 is not fixed on the upper surface of the cooler 10 and the ice making capacity varies depending on the position where the ice tray 18 is placed, so that the ice making time becomes longer. When the ice tray 18 is installed, there is a reasonable space between the top surface of the inner box 3 and the cooler 10 with good operability. Lower food, I could not really refrigerator of miniaturization for storage ensuring such as cans.

An object of the present invention is to solve the conventional problems and to provide a refrigerator having a good ice-making ability and a smaller refrigerator by making a part of the cooler concave.

[0011]

According to the present invention, there is provided a cooling device having a concave portion provided in a part thereof and an ice tray installed in the concave portion. Thus, the cooling pipe can be set in consideration of the storage of the ice tray. The cooler can be close to the top of the inner box.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to an outer box, an inner box, a heat insulating material filled between the two boxes, an electrical component box for storing electrical components and the like on the top right side of the inner box, A cooler in which a cooling pipe through which a refrigerant is installed between a box and an electrical component box is a one-sided expanded cooler, and a frost pan installed below the cooler, and a part of the cooler is formed in a concave shape, An ice making cooling pipe is provided in the recess.

[0013] By accommodating the ice tray in the recess, it is possible to provide a refrigerator having good ice-making ability.

The cooler is provided with a compact refrigerator by being close to the top surface of the inner box.

Further, in order to enhance the cooling effect and the workability of the cooler, the cooler is constructed so as to be expanded on both sides.

When the ice tray is installed, the front surface of the cooler is inclined downward to improve the operability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a refrigerator according to the present invention will be described below with reference to the drawings. The same components as those in the related art are denoted by the same reference numerals, and detailed description is omitted.

FIG. 1 is a perspective view of a refrigerator of a refrigerator according to an embodiment of the present invention.

FIG. 2 is a cross-sectional view of the refrigerator of the embodiment. FIG. 3 is a front view of the refrigerator of the embodiment.

The difference from the conventional example shown in FIGS.
A point that a recess 22 for accommodating an ice tray is provided in a part of the cooler;
The point is that the shape of the frost receiving tray and the cooling pipe through which the refrigerant of the cooler passes are changed based on this.

The refrigerator configured as described above will be described. A hook part 21 protruding from an electrical component box 20 attached to the upper right of the inner box 3 is hooked, and a cooler 23 having an L-shaped part with a concave portion 22 is attached to one side of the inner box.

The cooler 23 has a cooling pipe 1 through which a refrigerant passes.
3, and the cooling pipe 13 is provided in the recess 22 with the inlet pipe 24.
The installation is concentrated directly from. After passing through the recess 22, the cooling pipe 13 passes through the remaining surface to the outlet pipe 25, and the refrigerant is returned to 6 after compression.

The frost receiving plate 26 has a concave portion in a shape corresponding to the cooler 23, and collects defrost water through the connecting pipe 16 and discharges it to the evaporating plate 17 as in the conventional example.

Since the ice tray 18 is housed in the recess 22 of the cooler 23 as a dedicated place, a refrigerator having a stable ice making capability can be obtained. The cooler 23 is also provided with the concave portion 22 of the cooler 23.
Otherwise, the refrigerator can be made smaller because it can be close to the top surface of the inner box 3. The front surface 27 of the cooler 23 may be inclined downward for storing the ice tray 18.

[0025]

As described above, according to the present invention, a concave portion provided with a cooling pipe dedicated to ice making is provided in a part of the cooler, the ice tray is stored, and the cooler is brought close to the top surface of the inner box. Thereby, it is possible to provide a refrigerator having a stable ice-making ability with a short ice-making time and good can storage.
