Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The refrigerator partitioning device of the present invention relates to a device for partitioning the inside of one refrigerator to store articles having different storage temperatures.

[0002]

[Prior Art]

 Conventionally, in order to partition the inside of the refrigerator, a fixed or movable partition wall is provided across the inside of the refrigerator.

FIG. 4 schematically shows an example of such a conventional partition device. Reference numeral 1 is a refrigerator made of a heat insulating material, which is cooled by cold air blown into the refrigerator from a refrigerator 2 provided outside the refrigerator through a duct 3. Reference numeral 4 is a partition wall that divides the interior into a first chamber in which the duct 3 is open and a second chamber in which the duct 3 is not open. A fan 5 that sends air from the first chamber to the second chamber is provided above the partition wall, and a through hole 6 that allows both chambers to pass through is provided below the partition wall.

Since the cool air is directly sent from the duct 3 to the first chamber, the temperature becomes the lowest, and the cool air in the first chamber is sent to the second chamber by the fan 5. When the operation of the fan 5 is stopped, the temperature of the second chamber gradually rises, and when the fan 5 is operated again, the temperature of the second chamber becomes low again. Accordingly, by controlling the operation of the fan 5, the temperature of the second chamber can be kept at a low temperature higher than that of the first chamber.

The air blown into the second chamber by the fan 5 enters the first chamber through the through hole 6, is taken into the refrigerator 2 together with the air in the first chamber, and is cooled again.

By moving the partition wall 4 in the left-right direction in FIG. 4, the sizes of the first chamber and the second chamber can be changed.

[0007]

[Problems to be solved by the device]

 It is troublesome to construct a partition in the refrigerator, and the amount of work is large.

[0008]

[Means for solving the problem]

 In this invention, a wide air flow is blown from the ceiling of the refrigerator to the floor, the air curtain function of this air flow partitions the interior of the refrigerator, and the air flow is intermittently controlled to control the temperature.

[0009]

[Action]

 The wide air flow blown from the refrigerator ceiling toward the floor forms an air curtain that divides the refrigerator into two rooms.

The temperature of the two partitioned chambers is low in the first chamber where the cool air is directly sent from the duct, and is relatively high in the second chamber which is cut off from the cool air by the air flow.

When the blowing of the air flow is temporarily stopped, the air in the first chamber and the air in the second chamber are mixed, and the temperature of the second chamber becomes lower than before.

When the blowing of the air flow is restarted, the temperature of the second chamber is kept at this lowered temperature, but the temperature of the second chamber is kept due to the entry of heat from the outer wall of the refrigerator and the entry of outside air due to the loading and unloading of cargo. Get higher At this time, the air in the first chamber is allowed to enter the second chamber again except for the air curtain caused by the air flow to lower the temperature in the second chamber.

【Example】

 FIG. 1 is a vertical sectional view of a refrigerator schematically showing a first embodiment of the present invention.

On the ceiling 1a of the refrigerator 1, there is provided a wide discharge fan 7 that sucks in the air in the refrigerator and blows the air at a high speed immediately below the entire width of the refrigerator. The airflow 8 blown out from the fan 7 proceeds directly below, bends toward the suction port 2a of the refrigerator 2 near the floor 1b of the refrigerator, and is sucked into the suction port 2a.

This air flow 8 acts as an air curtain and divides the inside of the refrigerator into a first chamber A in which the duct 3 of the refrigerator is opened and a second chamber B in which the duct is not opened.

The first chamber A is cooled to a low temperature because it is the cold air blown from the duct 3, but this cold air is blocked by the air flow 8 and does not flow into the second chamber B. Higher than 1 room.

When the temperature of the second chamber B becomes higher than a predetermined temperature, the temperature sensor 9 provided in the second chamber operates to stop the discharge fan 7. As a result, the cold air in the first chamber A flows into the second chamber B, and the temperature of the second chamber is lowered.

When the temperature of the second chamber B falls, the sensor 9 operates to rotate the discharge fan 7 again, and creates the air flow 8 to shut off both chambers. As a result, the second chamber B is kept at a higher temperature than the first chamber.

Since the lower end of the air flow 8 bends in the direction of being sucked into the suction port 2a of the refrigerator, the partition action is weakened. However, in order to strengthen this action at the lower end of the air flow as well, a normal air cover is used. A suction fan may be provided on the floor of the refrigerator like a ten-unit device.

FIG. 2 shows a second embodiment in which a rail 10 is provided on the ceiling 1a of the refrigerator, and the discharge fan 7 is moved in the direction away from the refrigerator 2 and then fixed in position. As a result, the size of the first chamber A and the second chamber B can be adjusted according to the property and quantity of the cargo.

FIG. 3 shows a third embodiment in which two discharge fans 7 are provided in order to further strengthen the wall action of the air flow 8.

[0022]

[Effect of the device]

 (1) Since the first chamber A and the second chamber B are divided by the air flow, the equipment is simpler than the conventional partition wall provided in the refrigerator. Providing the discharge fan 7 is easier than installing a partition wall.

(2) The size of the first chamber and the second chamber can be changed by changing the position of the air flow to easily respond to the property and quantity of the cargo.

(3) The temperature of the second chamber B can be kept substantially constant by controlling the operation of the discharge fan 7 with the temperature sensor 9.

(3) This device can be used not only in a stationary refrigerator but also in a vehicle-mounted refrigerator.
