Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a refrigerator showing one embodiment of the present invention. FIG. 2 is a sectional view of a main part of the top table of the refrigerator according to the present invention.

Reference numeral 1 denotes a refrigerator main body having an open front surface, reference numeral 2 denotes a door for opening and closing the opening of the refrigerator main body 1, and reference numeral 3 denotes a top table mounted on an upper end of the refrigerator main body 1.

The refrigerator body 1 includes an outer box 6 formed by both side walls 4 and a back wall 5 provided on the back side of the side wall, and an inner box 7 arranged at an interval inside the outer box and having an open front. A foam insulation material 8 is provided between the inner box and the outer box and between the inner box and the top table 3. A flange 9 is formed at the open end of the inner box 7 from inside to outside, and the upper end of the flange is formed at the same height as the upper ends of the side walls 4 and the back wall 5 of the outer box 6.

The top table 3 is made of a synthetic resin-made top table body 10 that is horizontally fixed to the upper end of the outer box 6 and the upper end of the flange 9 of the inner box 7, and a heat-resistant metal material such as stainless steel. And a table section 11 formed. The top table body 10 has a bent piece 12 which is bent downward toward the periphery, and has a front end protruding forward from the outer box 6 so as to be flush with the door 2. The top table body 10 has a rectangular recess 13 formed therein. The table 11 is fitted in this recess. This table portion is composed of a flat plate 14 and leg pieces 15 formed around the flat plate toward the lower side. The table portion 11 forms a space 16 inside by fitting into the recess 13 of the top table body 10.

(4) The table portion 11 is substantially the same height or slightly higher when fitted into the recess 13 of the top table main body 10 so as not to be lower than the periphery of the top table main body 10.

In the refrigerator with the top table configured as described above, the refrigerator incorporates the top table 3 at the upper end of the refrigerator main body 1 formed by the outer box 6 and the inner box 7, and fills the foamed heat insulating material 8 therebetween. It is formed by attaching the door 2.

(4) The outer box 6 and the inner box 7 of the refrigerator body 1 and the top table body 10 of the top table 3 are adhered by the adhesive force of the foam insulating material 8 at the time of solidification of the foam insulating material, so that a special fixing tool is not required.

The top table body 10 of the top table 3 holds the bent pieces 12 at the upper ends of the side walls 4 and the back wall 5 and, by projecting the recesses 13 downward, is adhered and fixed by the foamed heat insulating material 8 which solidifies, and The gap is prevented from occurring. By mounting the table portion 11 in the recess 13 of the top table body 10, a space 16 is formed between the top table body 10 and the flat plate 14 in the recess, and this space can be made into a heat insulating space. It has been like that. For this reason, even if a high-temperature heating device such as an oven or a microwave oven is placed on the table portion 11 and used, the heat of the high-temperature heating device is less likely to be transmitted to the outer box 6 and the foam insulating material 8. Secondary foaming due to reheating of the foamed heat insulating material 8 can be prevented.

The table portion 11 and the recess 13 of the top table main body 10 are formed in a square shape, so that the table portion 11 can be easily mounted in the recess 13. Further, the table portion 11 is made substantially the same height or slightly higher than the periphery of the top table main body 10 so that the table portion 11 does not come into direct contact with the top table main body 10 even if the high temperature heating device is displaced. I have.

The air in the space 24 formed in the space 24 is made to enter and exit, and the air in the space 24 is prevented from becoming high temperature by the high-temperature heating device.

FIG. 4 shows another embodiment, in which a heat insulating material 32 is mounted in a space 31 of a table portion 30 so that heat of a high-temperature heating device placed on the table portion 30 is hardly transmitted to the outer box 33 and the foamed heat insulating material 34. ing.

FIG. 5 shows another embodiment, in which a heat conducting member 44 with one end facing a cooling chamber 43 formed in an inner box 42 is interposed between a top table main body 40 and a foamed heat insulating material 41 so as to be topped. The recess 45 of the table main body 40 is cooled so that the temperature of the top table main body 40 does not rise due to heat from the high-temperature heating device mounted on the table section 46.

FIG. 6 shows another embodiment, in which the table section 50 is sufficiently higher than the top table body 51, and holes 53 are provided at positions higher than the top table body 51 of the leg pieces 52 of the table section 50, and the top table body 51 The recess 58 of the top table main body 51 is cooled by interposing a heat conducting member 57 having one end connected to the accumulator 56 between the low-temperature portion of the refrigerating device that cools the cooling chamber 55 and the foamed heat insulating material 54, thereby cooling the table portion 50. In addition to preventing the temperature of the top table main body 51 from rising due to heat from the high-temperature heat-generating equipment placed on the table unit 50, the air in the space 59 formed inside the table unit 50 is made to enter and exit through the holes 53, The high temperature heating equipment keeps the temperature from getting high.
