Description

[Detailed description of the invention] This invention relates to a cold air passage structure for a refrigerator.

Conventionally, there have been refrigerators of this type as shown in FIGS. 1 and 2. In the figure, 1 is the refrigerator main body, 2 is a partition wall that divides the inside of the refrigerator into a freezer compartment 3 at the top and a refrigerator compartment 4 at the bottom, and 5 is an insulating partition wall 6 at the back of the freezer compartment 3. This is a divided heat exchange room in which a fan 7, a cooler 8, and a defrosting heater 9 are arranged. Reference numeral 10 denotes an outlet for supplying cold air into the freezer compartment 3, and this cold air is circulated from the suction opening 11 and the suction duct 12 of the partition wall 2 to the heat exchange chamber 5. Reference numeral 13 denotes a central duct partitioned off by a partition plate 14 at the back of the heat exchange chamber 5. Cold air is supplied from this duct 13 into the refrigerator 4, and then from a suction duct 15 in the middle partition wall 2 to the heat exchange chamber 5. It is circulated. 16 is a damper thermostat that adjusts the temperature of cold air flowing into the refrigerator compartment 4.

Since the refrigerator configured as described above is a two-door refrigerator consisting of two compartments, the freezing compartment 3 and the refrigerating compartment 4, it is inconvenient to use the compartments separately.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above, and it was a three-door refrigerator that made it possible to use the inside of the refrigerator for different purposes. is intended to provide.

An embodiment of this invention will be described below with reference to the drawings. In Figures 3 and 4, 17 is the refrigerator body, 1
8 is an upper partition wall that divides the inside of the refrigerator into an upper freezer compartment 19 and a lower freezer compartment 20; 21 is a lower freezer compartment 20;
This is a lower partition wall that partitions the refrigerator compartment 22 into a refrigerator compartment 22 and a refrigerator compartment 22. Reference numeral 23 denotes a heat exchange chamber partitioned by a heat insulating wall 24 serving as a heat insulating partition wall and a partition plate 25 at the back of the freezer compartments 19 and 20, in which a fan 7, a cooler 8 and a defrosting heater 9 are arranged. It has been done. Reference numeral 10 denotes an outlet for supplying cold air into the upper freezing chamber 19, and this cold air is circulated from the inlet 11 and the suction duct 26 of the upper partition wall 18 to the heat exchange chamber 23. 27
is the suction port 24 of the insulation wall 24 as shown in FIG.
This is a blow-off duct provided on the upper partition wall 19 that sends the cold air sucked in from a to the lower freezer compartment 20, and the outlet thereof is equipped with a damper thermostat 28 that adjusts the temperature of the cold air. The cold air in the lower freezing chamber 20 is circulated to the heat exchange chamber 23 from a suction duct 29 provided in the lower partition wall 21. Reference numeral 30 denotes a central duct partitioned off by a partition plate 31 at the back of the heat exchange chamber 23, which supplies cold air from the air outlet 24b of the heat insulating wall 24 to the refrigerator chamber 22 via the central duct 30, and this cold air passes through the lower partition wall. It is circulated to the heat exchange chamber 23 from a suction duct 32 provided in the heat exchange chamber 21 . A damper thermostat 16 is installed at the outlet of the central duct 30 and adjusts the temperature of cold air flowing into the refrigerator compartment 22.

As mentioned above, the air passage structure of the refrigerator according to this invention is such that cold air is supplied to the upper freezing compartment 19 from the outlet 10 and circulated from the suction opening 11 and the suction duct 26 of the upper partition wall 18 to the heat exchange chamber 23. In addition, cold air to the lower freezer compartment 20 is supplied from the blow-off duct 27 of the upper partition wall 18 and circulated from the suction duct 29 of the lower partition wall 21 to the heat exchange chamber 23. The cold air to the refrigerator compartment 22 is fed from the central duct 30 and circulated from the suction duct 32 of the lower partition wall 21 to the heat exchange chamber 23.

As mentioned above, according to this invention, the inside of the refrigerator can be
This is a so-called three-door refrigerator with two freezer compartments and one refrigerator compartment, and has an air passage structure that effectively cools each compartment, making the interior of the refrigerator more versatile than conventional refrigerators. There is an effect that can be achieved.
