Description

[Detailed Description of the Invention] The present invention relates to a refrigerator-freezer that is forcibly cooled by a fan.

Conventional refrigerator-freezers are commercially available that have fixed internal volumes for both the freezing and refrigerating compartments, and users select and purchase one with a desired internal volume.

However, once a refrigerator/freezer is selected, both the freezer compartment and the refrigerator compartment are fixed at a constant volume.

Due to future eating habits and the spread of frozen foods and items that require refrigeration, there is a strong demand for refrigerator-freezers with a freezer compartment that can be switched between a freezer compartment and a refrigerator compartment within a fixed internal volume. There is.

However, in order to meet this demand, even if you currently have a refrigerator-freezer, you must purchase a new refrigerator or freezer, which requires extra space and increases costs.

Although it would be good to have a refrigerator-freezer with a large internal volume, it would be necessary to cool unnecessary parts that do not store food, which would only increase power consumption, which is a problem.

In other words, within the fixed internal volume of a refrigerator-freezer, there is a demand for a refrigerator-freezer that is equipped with a refrigerator-freezer compartment that can be switched and controlled to function as both a freezer compartment and a refrigerator compartment, in addition to a fixed compartment that controls the freezing and refrigerating compartments. It is something that

The purpose of the present invention is to solve the above-mentioned drawbacks of conventional refrigerator-freezers by providing three independent compartments: a freezing compartment, a refrigerator compartment, and a freezer-refrigerator compartment that can be switched between the refrigerator compartment and the freezing compartment. One evaporator and one fan are provided for forced convection cooling of the room, and an air path for returning cold air from the freezing room to the evaporator is provided in the partition between the freezing room and the freezing/refrigerating room. , a damper thermostat that adjusts the amount of cold air discharged from the middle of the air path into the freezing/refrigerating room according to the temperature inside the room or the ambient temperature outside the refrigerator is provided in the air path, and the cold air from the freezing room is directed into the air path. This invention provides a refrigerator-freezer equipped with a fixed freezer compartment and a refrigerator compartment, and a freezer/refrigerator compartment that can be switched and controlled to be either a freezer compartment or a refrigerator compartment by providing a wind direction plate that guides the air inside or directly into the freezer/refrigerator compartment. .

The present invention will be explained below with reference to examples.

A position where cold air from the freezer compartment 1 is guided to the air passage (Fig. 2), and a position where the air passage is blocked and cold air is guided to the freezer/refrigeration compartment (Fig. 3).
It can take two positions (Fig.).

To explain the wind direction plate in more detail with reference to FIG. 4, one wind direction plate 22a is attached to the partition part by a pin 23a, and the other wind direction plate 22b is attached to the partition part by a pin 23b. 22a and 22b are pin-jointed to both ends of the connecting rod 24 so that they interlock together.

25 is a switching cam for positioning the wind direction plate 9;
When set in this position, the wind direction plate 22b pushed up by the switching cam 25 prevents cold air from flowing into the freezer/refrigerator compartment 3.

If the switching cam 25 is rotated in the direction of the arrow and brought to the position shown in FIG.

12 is a cold air suction port that sucks the return cold air from the freezer/refrigerator compartment 3 into the cooling compartment 21 side.

Next, the operation of this embodiment will be explained.

First, the case where the freezing/refrigerating compartment 3 is controlled as a refrigerating compartment will be explained with reference to FIG.

The wind direction plate 9 is set to the position shown in FIG. 2 by the switching cam 25.

When the refrigerator-freezer is energized, a compressor (not shown) and a fan motor are driven, and air cooled by the evaporator 4 is discharged from the cold air outlet 10 to the freezer compartment 1 by the fan 5 .

After the cold air discharged to the freezing compartment 1 cools the freezing compartment 1, a part of the cold air is discharged to the refrigerator compartment 2 via the damper thermometer 6,
After cooling the refrigerator compartment 2 , the cold air is discharged from the return port 20 to the back of the freezer/refrigerator compartment 3 and further sucked into the cooling compartment 21 .

On the other hand, the remaining cold air is guided from the cold air suction port 11 to the air path of the partition section 7, and a part of it is discharged to the freezer/refrigerator compartment 3 via the damper thermostat 8.

The remaining cold air that was not discharged passes through the air path and enters the cooling chamber 21.
be sucked into.

The cold air discharged from the damper thermostat 8 cools the freezer/refrigerator compartment 3, then exits from the cold air suction port 12, and is sucked into the cooling compartment 21 together with the return cold air from the refrigerator compartment 2 coming out from the cold air return port 20 for circulation.

Next, a case where the freezing/refrigerating compartment 3 is controlled as a freezing compartment will be explained with reference to FIG. 3.

The switching cam 25 is pushed down and the wind direction plate is set as shown in FIG. 3 to block the air passage of the partition 7.

In this way, all the cold air that has entered the cold air suction port 11 from the freezer compartment 1 is discharged to the freezer/refrigerator compartment 3.

Therefore, the freezing/refrigerating compartment 3 is cooled to the same temperature as the freezing compartment 1.

The cold air that has cooled the freezer/refrigerator compartment 3 is sucked into the cooling compartment 21 through the cold air suction port 12 and circulated.

As explained in detail above, according to the present invention, an air passage is provided in the partition between the freezer compartment and the freezer/refrigerator compartment to return cold air from the freezer compartment to the evaporator, and an air passage from the middle of the air passage to the freezer/refrigerator compartment. By providing a damper thermostat that adjusts the amount of cold air discharged into the refrigerator compartment, and by providing a wind direction plate in the air path that guides the cold air from the freezer compartment to the air passage or directly into the freezer/refrigerator compartment, By providing a refrigerator-freezer equipped with a freezer compartment, a freezer compartment, and a refrigerator compartment that can be controlled to switch between a freezer compartment and a refrigerator compartment, it is possible to use the refrigerator for multiple purposes according to the intended use with the same space and price as a conventional refrigerator-freezer. can.

For example, if the freezing and refrigerating room is controlled as a freezing room, and processed food and frozen food are stored separately, the refrigerating room can be used as a dedicated storage room for vegetables, fruits, beer, etc.

Furthermore, since it is a three-door refrigerator-freezer, it reduces heat leakage and saves power, which has great effects in terms of performance and product value.
