Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator. Specifically, the present invention relates to a refrigerator equipped with a dedicated freezing compartment and a dedicated refrigerating compartment. This relates to refrigerators and freezers.

Conventionally, commercially available refrigerator-freezers take into consideration that there are fewer frozen foods than refrigerated foods, and the size of the freezer compartment is smaller than that of the refrigerator compartment.

However, recently, frozen foods have started to become available in large quantities.
Even in this type of refrigerator-freezer, the ratio of the freezer compartment to the refrigerator itself is increasing year by year. However, since some users do not fully accept this trend, it has become most desirable for users to be able to increase or decrease the internal volume of the freezer compartment as needed.

The present invention has been made in view of these points, and consists of a refrigerator-freezer consisting of a cold storage compartment, a refrigerating compartment, and a switching compartment (freezer compartment/refrigeration compartment), and a mechanism for adjusting the amount of cold air to adjust the indoor temperature of the switching compartment. The switching chamber can be switched between a freezing chamber and a refrigerator, and the volumes of the refrigerator and freezing chambers can be increased or decreased as necessary.

The details of the present invention are shown in the figures below and will be explained by examples.
is the main body of the refrigerator, which has a switching chamber in addition to the freezing and refrigerating compartments.

Reference numeral 2 denotes a door that closes the front entrance of the freezer compartment, 3 a door that closes the front opening of the refrigerator compartment 3a, and 4 a door that closes the front entrance of the switching chamber, which will be described later.

Reference numeral 5 indicates the freezing room, 6 a switching room, 7 a condenser, and 8 a compressor, which are installed in the machine room 9.

Reference numeral 10 denotes a partition wall that separates the freezer compartment 5 and the sliding door compartment 6.

A cooler 11 is provided on the back wall of the switching chamber 6, and together with the condenser 7, compressor 8, etc., constitutes a refrigeration cycle.

Reference numeral 12 denotes a partition plate provided on the front surface of the cooler 11, and its upper end is connected to a duct plate 13 that guides the cold air cooled by the cooler 11 to the freezer compartment 5.

Reference numeral 14 indicates a cold air discharge hole provided at the upper part of the duct plate 13.

Reference numeral 15 denotes a blower provided in the cold air discharge hole 14, which is driven by a drive motor 16.

Reference numeral 17 indicates a cold air blowing hole to the freezer compartment 5.

Reference numeral 18 denotes an ice-making chamber provided immediately near the blow-off hole 17.

19 directs a part of the cold air discharged from the discharge hole 14 to the pressure chamber 2.
5. It is a partition duct plate.

This partition duct plate 19 forms the apparent back surface of the freezer compartment. Reference numeral 20 denotes a cold air suction port of the freezer compartment 5 provided with an inner partition wall 101.

The cold air after cooling the freezer compartment sucked in from this suction port 20 is transferred to a cold air passage 21a formed in the Nakatsuji cut wall 10 and a cold air passage 2.
A part of the air is blown into the switching chamber 6 through the passage 21, and the rest is blown out through the passage 21.
It reaches the pressure chamber 25 through b. 23 is a damper thermostat that adjusts the amount of cold air blown into the refrigerator compartment 6.

This damper thermostat 23 is installed in the cold air passage 22. 24 indicates a cold air outlet to the switching chamber.

One end of the cold air passage 22 having the damper thermostat 23 faces this air outlet hole 24 . Further, one end of a cold air passage 21b, a cold air passage 22, and a cold air passage 26 formed between the duct plate 13 and the partition duct plate 19 are closed in the pressure chamber 25. Reference numeral 27 denotes a partitioning thermal wall provided to form a return passage 28 between it and the partition plate 12 provided at the front of the cooler 11, and also to form an apparent back wall of the switching chamber 6a.

The return passage 28 has one end connected to the pressure chamber 25 and the other end closed to the air intake port 29 of the switching chamber. This is a cut-sliding damper installed inside the pressure chamber 25.

This switching damper 30 is connected to the cold air passage 26 and the cold air passage 21.
It is possible to select whether the cold air entering the pressure chamber 26 through b is sent to the cold air return passage 28 side or to the air outlet hole 24 side of the switching chamber 6. 31 is a lever.

By operating this lever 31, the damper opens and closes the cold air passage. Here, how to use the partition will be explained with reference to FIGS. 3 and 4 (first, when the partition is used as a refrigerating room). At this time, the switching damper 30 is in the position shown by the solid line in FIG. When the refrigerator starts operating in such a state, the cold air cooled by the cooler 11 passes through the duct plate, reaches the blower 15, and most of it is blown out from the cold air outlet 17 into the freezer compartment 5. On the other hand, the remaining cold air reaches the pressure chamber 25 from the cold air passage 26, then returns to the cooler 11 via the cold air passage 28.
The cold air blown into the freezer compartment 5 cools the inside of the freezer compartment 5, and then is sucked in through the air suction port 20 provided in the partition wall, and reaches the cold air passage 21. Next, it reaches the switching chamber via a cold air passage 22 in which a damper thermostat 23 for automatic cold air adjustment is provided. At this time, the cold air that is prevented from being blown into the switching chamber 6 by the damper thermostat 23 is returned to the cooler via the cold air passage 28. On the other hand, the cold air that has cooled the switching chamber 6 is transferred to the cold air suction port 2.
9 to form a cold air circulation path that returns to the middle of the cooler. A part of the cold air blown out from the blower 15 passes through a damper thermostat 32 for automatic cold air adjustment, reaches the refrigerator compartment 3a, and then returns to the cooler 11. The period number 33 shown in FIG. 2 is the return port from the refrigerator compartment 3a. In addition, the inside of the switching chamber 6 should be used as a freezing chamber. (If the switching damper 30 is moved to block the cold air passage 28 side as shown by the broken line in FIG. Since the damper thermometer is completely blocked, the cold air that has passed through the freezer compartment 5 will enter the switching chamber via the switching damper 30, and the cold air that has not passed through the freezer compartment 5 will also be discharged into the switching chamber 6. On the other hand, a cold air passage is formed which returns to the cooler 11 via the damper thermostat 32, the refrigerator compartment 34, and the cooler 11.
Here, the structure of the switching damper 30 that uses the sliding door compartment 6 as a freezer compartment or a refrigerator compartment will be explained with reference to FIGS. 2 and 5. 3
1, the damper 30a slides. That is, the lever 31 causes the damper 30a to always close one of the two passages provided in the switching damper 30 (the passage returning to the cooler 11, ie, the cold air passage 28 and the passage leading to the cold air outlet 24). Fulcrum 31 of lever 31
It moves around a. At this time, the lever 31
is movable in the depth direction as shown in FIG. 31b is a display section provided at the tip of the bar 31 mentioned above.

This display section 31b has sides A and B, and the A side is exactly B when viewed from the front when the display section 31b is on the partitioning thermal wall 27 side.
The surface is shaped so that it can be seen from the front when it is on the side of the partition wall. Therefore, using these A and B sides, the user can check which side this switching damper is currently located on.
, can be easily determined by looking at the characters written on side B. In addition, the bar 31 itself, as mentioned above, is located in the middle partition wall using the recessed part for forming the air blowing hole 24 so that it does not interfere with the stored items in the switching chamber, and the bar 31 itself is located in the partition wall 27 side so that it does not interfere with the stored items in the switching chamber. It is designed to be absorbed by the oblique part 27a of the partitioning thermal wall 27. As explained above, the present invention is provided between the freezing compartment and the switching compartment.

In the refrigerator', a switching damper is provided in the pressure chamber to change the switching chamber into a freezing chamber or a refrigerating chamber, and the damper is operated by a lever provided so as to protrude toward the sliding door chamber. The above-mentioned lever is rotatable in the depth direction of the switching chamber, and a display part having both sides A and B is provided at the tip of the lever, so that one side of the display parts A and B can be seen from the front when the door is opened. The lever allows the user to visually check the current state of the sliding door, and the lever is designed to not get in the way of stored items by using recesses in the inner walls, etc., making it easy to use. In addition, according to the present invention, if necessary, the switching chamber can be made into a freezing room or a refrigerating room simply by operating the switching damper.
