A duct is fixed to the back wall of the inner box 2 with screws or the like so as to cover the re-cooled air discharge ports 11 and 12, and 14 is a duct plate fixed to the duct 13 so as to come into contact with the rear part of the partition wall. , the back wall of the inner box 2, the duct plate 14 and the duct 13
As a result, a cold air supply path 15 for supplying cold air from the cooler 8 into the refrigerator is formed.

Reference numeral 16 denotes an electric blower that circulates air between the cooler 8 and the inside of the insulation box 4 via the cold air supply path 15, and 17 is located in the cold air supply path 15 facing the cold air outlet 10. A fan 18 of the electric blower 16 is a storage chamber 2 for the electric motor 19 of the electric blower 16 formed by expanding into the duct 13.
0 is a heat insulating member fixed to the inside of the duct 13 so as to cover the opening of the storage chamber 18, and the rotating shaft 21 of the electric blower 16 passes through it.

Reference numeral 22 denotes a heat conductive member such as a metal scrubber-shaped aluminum material interposed between the outside of the storage chamber 18 and the outer box 1, and the heat conductive member 22 is compressed to such an extent that the heat insulating material 3 does not enter.

Then, while the electric blower 16 is being driven, the heat generated by the electric motor 19 is conducted to the outer box 1 via the heat conduction member 22.
Heat is radiated using the outer box as a heat radiating surface, preventing the temperature inside the storage chamber 18 from rising, and the heat insulating member 20 prevents the electric motor 19 from releasing heat into the refrigerator.

Furthermore, since the vibrations of the electric motor 19 are attenuated by the heat conductive member 22 and transmitted to the outer box 1, the outer box 1 has less vibration and quiet operation is performed.

Next, FIGS. 3 and 4 showing other embodiments will be explained.

The same symbols as above indicate the same things, and 23 is a partition plate that is provided in the heat insulating box body 4 at a distance from the back wall of the inner box 2 and forms the cold air supply path 15, and the back wall of the inner box 2 and the partition plate A cooler 8 is interposed between it and 23.

24 is an intake port formed at the bottom of the partition plate 23; 25 is an exhaust port formed at the top of the partition plate 23;
A fan 17 of an electric blower 16 is provided facing the.

Reference numeral 26 denotes a mounting plate having good thermal conductivity, such as aluminum, which is provided on a part of the back wall of the inner box 2 in contact with the heat insulating material 3, and the electric blower 16 is mounted on the mounting plate 26.

Reference numeral 27 denotes a heat insulating member that covers the motor 19 of the electric blower 16. The rotary shaft 21 of the blower 16 passes through the heat insulating member 27, and the heat insulating member 27 is fixed to the back wall of the inner box 2 to form a storage chamber for the motor 19. 18 are configured.

28 is a heat conductive member such as a pipe-shaped aluminum material interposed between the mounting plate 26 and the outer box 1.

During the operation of the electric blower 16, the heat generated by the electric motor 19 is transferred to the outer box 1 through the mounting plate 26 and the heat conduction member 28.
The heat is conducted to and radiated to prevent the temperature inside the storage chamber 18 from rising, and the heat insulating member 27 prevents the electric motor 19 from releasing heat into the refrigerator.

In the second embodiment, since the fan 17 and the electric motor 19 of the electric blower 16 can be assembled in advance via the heat insulating members 20 and 27, the fan 17 may be installed unevenly with respect to the rotating shaft 21. Therefore, eccentricity does not occur when the fan 17 rotates, and a constant amount of air is always blown, improving productivity.

Further, the electric blower 16 can be replaced from inside the refrigerator.

As described above, according to the storage of this invention, the inner box is stored in the outer box with a gap between them, and the space is filled with heat insulating material to cool the inside of the insulated box. a cooler for cooling, a cold air supply path for supplying cold air from the cooler to the inside of the refrigerator;
In a refrigerator equipped with an electric blower that circulates air between the cooler and the inside of the refrigerator via a cold air supply path, the fan of the electric blower is installed in the cold air supply path, and the inside of the storage chamber of the blower's electric motor is By covering with a heat insulating material and interposing a heat conductive member between the outside of the storage room and the outer box, the heat emitted by the motor of the electric blower is released to the outside via the heat conductive member and the outer box. At the same time, the heat insulating material prevents conduction from the insulation box to the inside of the refrigerator, improving cooling efficiency, reducing the heat load for cooling the inside of the refrigerator, saving power, and reducing the temperature reached inside the refrigerator. It is possible to lower the operating rate.

Further, the temperature inside the storage chamber does not rise abnormally, and there is no fear of burning out the windings of the motor.

Furthermore, when the blower is stopped, the heat insulating member insulates the space between the storage chamber and the insulation box, which prevents heat from entering the chamber from the outside and prevents cooling inside the storage chamber. There is no hardening of the motor grease, the motor can be easily redriven, and a small capacity motor can be used.

Note that if the heat conductive member is made into a metal scrubber-like or honeycomb-like elastic shape, conduction of the vibrations of the motor to the outer box is attenuated, and quiet operation becomes possible.

Furthermore, if a material with good thermal conductivity is used for the outer wall of the storage chamber, the efficiency of heat conduction from the storage chamber to the heat conductive member can be increased.
