The step motor may be used to allow the door motor 52 to selectively control the degree of movement of the door 50. Of course, DC motors and servomotors may be used. The pinion gear 54 is provided on the rotation shaft of the door motor 52. In addition, the rack gear 56 is provided to mesh with the pinion gear 54. The rack gear 56 is provided to move integrally with the door 50.

Hereinafter, the operation of the home bar cold air supply device of the refrigerator according to the present invention having the configuration as described above will be described in detail.

The cold air generated in the heat exchange cycle of the refrigerator is supplied to the freezing compartment 22 and the refrigerating compartment 22 ', respectively. The cold air supplied to the freezing compartment 22 maintains a constant temperature inside the freezing compartment 22 while circulating the freezing compartment 22. Some of the cold air inside the freezing chamber 22 flows into the intake port 28.

The cold air introduced into the intake port 28 flows into the intake port 28 formed relatively lower than the discharge port 30 toward the storage space 38 as the low temperature cold, but cannot rise along the connection part 32 because of the density difference. It does not flow into the discharge port 30 does not flow into the storage space 44. Therefore, since cold air does not naturally flow into the storage space 44, the temperature of the storage space 44 is not necessarily maintained at a low temperature.

When the storage space 44 is to be kept at a low temperature, the fan assembly 34 is operated to drive the driving motor 36. When the drive motor 36 is driven, the fan 38 located on the axis of rotation rotates. As the fan 38 rotates, cold air of the freezing chamber 22 is introduced through the intake port 28 and discharged to the discharge port 30 along the connection part 32.

The drive motor 36 is a motor that can control the rotational speed, and can control the rotational speed of the fan 38. If the storage space 44 is to be quickly cooled, the drive motor 36 You can operate it to make the rotation speed faster.

The door 50 is also opened while the fan 38 is rotated by the drive motor 36. The door motor 52 that provides the power to open the door 50 can also control the rotation speed, and the door 50 can be opened as desired by the user.

Referring to the operation process of the door 50 is opened and closed in more detail, the pinion gear 54 located on the axis of rotation of the door motor 52 is rotated. As the pinion gear 54 rotates, the interlocking rack gear 56 rises, the door 50 also rises, and the through hole 46 is opened.

Then, when the operation unit is controlled to close the door 50, the door motor 52 is driven in the opposite direction, so that the pinion gear 54 and the rack gear 56 operate in the opposite direction. Therefore, when the rack gear 56 is lowered, the door 50 is also lowered, and the through hole 46 is shielded.

The cool air introduced into the intake port 28 by driving the fan assembly 34 overcomes the density difference by the height of the connecting portion 32 by the driving force of the fan assembly 34 and rises along the connecting portion 32. Done. Therefore, the discharge port 30 passes through the through hole 46 and is guided to the storage space 44. The cold air guided to the storage space 44 cools the food stored in the storage space 44.

When the temperature inside the storage space 44 drops to a lower temperature than necessary, the rotational speed of the driving motor 36 and the opening degree of the door 50 may be reduced, thereby preventing the inflow of cold air. Of course, if necessary, the cool air in the storage space 44 may be flowed into the freezing chamber 22 by reversing the rotation direction of the driving motor 36.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

For example, in the illustrated embodiment, the fan assembly 34 is installed on the communication passage 26. However, the fan assembly 34 may be installed adjacent to the through hole 46 corresponding to the inside of the storage space 44.

In the illustrated embodiment, although the shield 48 is employed as a door 50 that can move up and down along the sidewall of the storage space 44, the fan assembly 34 installed on the connection passage 26 is provided. Can be formed into a film film whose opening degree can be controlled by the size of the air flow generated in

Home bar cold air supply of the refrigerator according to the present invention as described in detail above can be expected the following effects.

That is, when the cold air of the freezer compartment flows into the storage space through the through-hole and the communication flow path, the cold air is quickly introduced into the storage space by the blowing means, thereby cooling the food stored in the storage space at a desired speed. .

In addition, since the intake port is located at a position relatively lower than the discharge port, low temperature cold air flowing into the intake port is blocked from flowing to the discharge port due to the difference in density, so that the storage space temperature is always maintained at a desired temperature by the user.

And, by using a motor that can control the rotational speed of the drive motor of the fan assembly and the motor for controlling the opening degree of the door for opening and closing the discharge port installed on the communication passage can maintain the temperature of the storage space quickly and precisely desired by the user It has an effect.
