Description

[Detailed Description of the Invention] The present invention relates to a so-called cold air forced circulation type refrigerator that forcibly circulates cold air into the refrigerator using a fan motor.

In this type of refrigerator, when the cold air cooled by the cooler is forcedly circulated by the fan motor, the motor section of the fan motor generates heat, and the cooled air is warmed by the motor section and circulated. As a result, cooling efficiency is extremely poor.

Therefore, a method has been proposed in which the motor section of the fan motor is installed outside the main body, but in this case, it is necessary to connect the motor section and the fan section with a shaft of a predetermined length, and to support the motor section with a separate bearing, etc. This has the disadvantage of requiring frequent assembly and high cost.

The present invention is intended to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a refrigerator body consisting of an outer box 2, an inner box 3, and a heat insulating material 4 filled between the boxes 2 and 3.

Inside this main body 1, a freezer compartment 6. It is divided into two compartments, a refrigerator compartment 7.

Reference numerals 8 and 9 denote doors that can be opened and closed at the front of these rooms.

A cooling chamber 11 is formed inside the partition wall 5 and communicates with a cold air passage 10 formed on the back side of the main body. Freezer compartment 6. A fan motor 13 for forced circulation to the refrigerator compartment 7 is provided.

13a is a motor. The cooler 12 is a compressor 14
．． Together with the condenser 15 and the like, it constitutes a well-known refrigeration cycle.

The bottom of the cooling chamber 11 is constituted by a drain pan 16, and its drain port 17 faces a drain channel 18 formed at the inner bottom of the partition wall 5.

This drainage channel 18 includes a drain guide 19 and a drain pipe 20.
It is led out to the back side of the main body 1 through.

On the other hand, the motor 13a of the fan motor 13 is covered with a sealed cover 21.
The opening faces the drainage channel 18.

Therefore, the heat generated by the motor 13a is not circulated into the refrigerator, but is discharged to the outside of the main body 1 or into the refrigerator compartment 7 through the drainage channel 18.

As is clear from the above description, the forced circulation refrigerator of the present invention is one in which cold air is forcedly circulated into the refrigerator from a cooling chamber housing a cooler, a fan motor, etc., and a cover that covers the motor part of the fan motor is provided. At the same time, this cover is opened to a drainage channel that discharges the defrosting water from the cooler to the outside of the main unit, and once cooled, the cool air mixes with the heat of the fan motor and flows into the refrigerator. The heat is discharged into the drain without being recycled.

Therefore, efficient cooling inside the refrigerator can be expected.
