The present invention relates to a refrigerator in which a refrigerating chamber is formed at an upper side of a refrigerating chamber and a vegetable compartment at a lower side thereof.

Refrigerators are usually arranged in order from the top to the freezer compartment, the refrigerating compartment and the vegetable compartment.

However, since the refrigerator is more frequently used than the freezer, in consideration of the opening and closing of doors and the ease of accessing food, the recent large refrigerators have been considered to be arranged from the top to the refrigerator, freezer and vegetable rooms.

On the other hand, in a so-called fan-cooled refrigerator, a cooler is conventionally arranged at the rear of the freezer compartment to send air cooled by the refrigerator to each room, and to return to the cooler through a dedicated return path of each chamber in each chamber.

In accordance with the prior art, in forming the refrigerating chamber, the freezing chamber and the vegetable compartment in the heat insulating box body from the top, the refrigerating chamber 2 and the freezing chamber 3 formed in the heat insulating box body 1 as shown in Figs. ) And a cooler chamber (6) having a cooler (5) arranged at the rear of the freezer (3) in the vegetable compartment (4), and cool air cooled by the cooler (5) directly by a fan device (7). And blows into the refrigerator compartment 2 and the vegetable compartment 4 via the refrigerator compartment ventilation path 8 and the vegetable compartment ventilation path 9 at the same time. The cold air sent into the temporary chambers 2 and 4 is configured to return to the cooler chamber 6 through dedicated return paths 10 and 12, respectively. Among these return paths 10-12, the refrigerating compartment 10 for the refrigerating compartment is formed from the upper insulation partition wall 13 to the left wall of the insulation box body 1 and the lower insulation partition wall 14. The outlet of the refrigerating compartment return path 10 is located at the left side of the outlet of the left side of the outlets of the two freezer compartment return paths 11 provided with the outlet of the vegetable compartment return path 12 in the center. It is connected to the bottom of the cooler chamber (5).

However, if the configuration as described above, the refrigerating compartment return path 10 passes through the left side wall of the heat insulation box body 1, so if the two left walls of the heat insulation box body 1 are not thickened, the freezer compartment 3 is insulated from the outside. The effect to do is lost. However, when the side wall of the heat insulation box 1 is thickened, the content is reduced compared to the size of the entire refrigerator, thereby reducing the amount of food that can be stored. In addition, the air returning from the refrigerating chamber 2 to the cooler chamber 6 is distributed to the air in the refrigerating chamber 3 and the high temperature and high humidity is introduced into the cooler chamber 6 at a position biased leftward. The tendency to rise along the left inner side of the cooler chamber 6 becomes stronger, so that the frost adheres to the left side of the cooler 5 thickly, causing a problem of significantly impairing the cooling effect of the cooler 5.

The present invention has been made in view of the above circumstances, and its purpose is to form a refrigerator compartment at the top of the freezer compartment and a vegetable compartment at the bottom thereof so as not to thicken the thickness of the insulation box caused by the return path for returning the cold air supplied to the refrigerator compartment to the cooler. At the same time, there is provided a refrigerator that is not likely to occur unevenly attached to the cooling properties.

The refrigerator of the present invention divides the inside of the insulating box body with an insulating partition plate to form a refrigerator compartment and an vegetable compartment at the upper side of the freezer compartment and to circulate the air cooled by a cooler for cooling such rooms. It is characterized in that for connecting the refrigerating compartment return path for returning the cold air sent to the refrigerating compartment through the vegetable compartment, and returning the cold air discharged into the vegetable compartment to the cooling through the vegetable compartment return passage.

The air to be returned from the refrigerating compartment to the cooler is once blown out of the refrigerating compartment return path into the vegetable compartment, and then returned to cooling through the vegetable compartment return passage. Therefore, unlike the conventional case where the refrigerating compartment return path had to be connected to the left end of the chiller chamber, for example, it does not need to be installed, and the refrigeration compartment return path is not insulated since it is not necessary to install the vegetable compartment ventilation path that sends the cold air from the cooler chamber to the vegetable compartment. It can be installed on the back wall of the box body. Since the back wall of the heat insulation box body is inherently thick, for example, a cooler chamber is installed, it is not necessary to make it thick even if a refrigerating chamber feedback circuit is provided.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4. In FIG. 1, the insulating partition walls 22 and 23 are installed in the single-reverse box body 21 in two upper and lower stages, and the insulating partition walls 22 and 23 are used in the thermal insulation box body 21. In the center, a freezer compartment 24, a freezer compartment 25 above the freezer compartment 24, and a vegetable compartment 26 below the freezer compartment 24 are formed.

A concave thread is formed in the rear portion of the freezer compartment 24 as shown in FIG. 4, and the concave thread is formed by the partition plate 27 in the freezer compartment 24, thereby forming the cooler chamber 28. It is. In the cooling chamber 28, as shown in FIG. 2, the fan apparatus 29 and the cooling 30 are arrange | positioned up and down, and the fan apparatus 29 carries the air cooled by the cooler 30 below. Circulate according to the path described.

That is, the air vent 31 is formed in the partition plate 27, and a part of cold air blown by the fan apparatus 29 is sent directly into the freezer compartment 24 from this air vent 31. As shown in FIG.

The cold air sent into the freezer compartment 24 is returned to the cooler chamber 28 through the freezer compartment return path 32 as shown in FIGS. 2 and 3. Two freezer return paths 32 are formed on each of the left and right sides of the lower insulating partition wall 23, and the inlets 32a are opened into the freezing chamber 24 at the front of the lower insulating partition wall 23. The outlet port (not shown) is opened in the left and right sides of the bottom of the cooler chamber 28 with respect to the cooler chamber 28.

On the other hand, the remaining part of the cold air blown by the fan device 29 is sent into the refrigerating chamber 25 through the refrigerating chamber ventilation path 33 formed in the insulating box body 21 as shown in FIG. 1 and FIG. . The refrigerating chamber ventilation path 33 is upwardly through the rear wall of the upper insulating partition wall 22 and the insulating box body 21 from the inlet 33a formed to face the upper insulating partition wall 22 into the cooler chamber 28. It is formed so that it extends, and the outlet 33b is opened in the upper part in the refrigerating chamber 25. As shown in FIG. The cold air sent into the refrigerating compartment 25 is sent into the vegetable compartment 26 through the refrigerating compartment return path 34, and the cold air sent into the vegetable compartment 26 is passed through the vegetable compartment return passage 35. It is supposed to come back to me.

However, the refrigerating compartment return path 34 extends from the inlet opening 34a formed at the center of the upper insulating partition wall 22 to the right side as shown in FIG. 1, and as shown in FIG. 21 extends downward from the position adjacent to the right side of the cooler chamber 28 in the rear wall, and the outlet 34b at the lower end thereof is opened into the vegetable chamber 26. Further, the vegetable compartment return path 35 is formed to be located between the two freezer compartment return paths 32 at the center of the lower insulating partition wall 23 as shown in FIG. 1 and its inlet as shown in FIG. 35a is opened into the vegetable chamber 26 at the front of the lower insulating partition wall 23, and the outlet 35b is the return path for both freezer compartments at the bottom of the cooler chamber 28 with respect to the cooler chamber 28. The opening is made to be located between the outlets 32b of the 32. In addition, an electric heater 36 for defrosting is provided below the cooler chamber 28.

In the above configuration, when the fan device 29 is started, a part of the cold air cooled by the cooling unit 30 is directly sent from the tuyeres 31 into the freezer compartment 24, and the cooler chamber via the freezer compartment return path 32. It is gentle to return to 28 and cool again by the cooler 30. In addition, the remaining part of the cold air cooled by the cooler 30 is circulated into the refrigerating chamber 25 through the refrigerating chamber channel 33. In addition, the remaining part of the cold air cooled by the cooler 30 is sent into the refrigerating chamber 25 through the refrigerating chamber blowing path 33. The cold air sent into the refrigerating compartment 25 is sent to the vegetable compartment 26 through the refrigerating compartment return path 34, and then returns to the cooler chamber 28 through the vegetable compartment return passage 35 to the cooler 30 again. Circulated to cool. Each chamber 24-26 is cooled by cold air circulating as described above.

In this case, although cold air after cooling the refrigerating chamber 25 is supplied to the vegetable chamber 26, since the vegetable chamber 26 does not need to be cooled to such a low temperature, there is no possibility that cooling of the vegetable chamber 26 will be impaired.

After cooling the inside of the freezer compartment 24, the air of relatively low temperature and low humidity flows into the cooler chamber 28 from the outlet 32b of the freezer compartment return path 32 opened at the left and right sides of the bottom of the cooler chamber 28. . In addition, the relatively high temperature and high humidity air after cooling in the refrigerating chamber 25 and the vegetable chamber 26 is carried out at the outlet 35b of the return path 35 for vegetable chambers opened in the bottom center part of the cooler chamber 28, and the cooler chamber 28 Flows into). Therefore, the air of the vegetable chamber 26, which is relatively hot and humid, diffuses while rising up the central portion of the cooler 30, so that adhesion to the cooler 30 is generally averaged, so that the cooling effect of the cooler 36 is not impaired. . Of course, when the compressor of the refrigeration cycle (not shown) is operated for a predetermined time, the defrosting heater 30 is energized to remove frost, so there is no fear that frost is attached to the cooler 30 in a large amount.

In addition, since the cold air supplied to the refrigerating chamber 25 is sent to the vegetable chamber 26, it is good to connect the refrigerating chamber return path 34 to the vegetable chamber 26. Therefore, unlike connecting the refrigerating compartment return path to the side end of the cooler chamber, the refrigerating compartment return path 34 is not installed in the right side wall of the insulated box body 21, but is the original cooler chamber of the insulated box body 21. (28) can be formed in the rear wall set thick for formation, so there is no fear that the contents of the heat insulation box 21 become narrow.

As described above, according to the present invention, the return path for returning the cool air supplied to the refrigerating chamber to the cooler does not have to increase the thickness of the side wall of the insulation box, and also achieves an excellent effect without the risk of biasing the cooler. .
