Description

[Detailed description of the invention] This invention relates to a cooling system for a four-door refrigerator in which a freezer compartment, an ice room, and a vegetable compartment are arranged sequentially from the top, each with a separate door.

Conventionally, various cooling systems for three doors in which a freezer compartment, a refrigerator compartment, and a vegetable compartment are arranged sequentially from the top have been proposed, such as in Utility Model Application No. 55-54874.
There was almost nothing about 4 doors.

This idea relates to a four-door cooling system that adds an ice chamber to the conventional three-door system.

This invention will be explained in detail below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a freezer compartment, which is controlled by a freezer compartment temperature controller 12 to turn on and off a compressor 29 to a temperature of around -18°C at which frozen foods can be stored. Reference numeral 2 denotes a cooler, which is controlled at around 0° C. and is installed in a cooler chamber 8 that is formed across the back of the ice chamber 10 and the rear of the freezing chamber 1, which is designed to store meat, fish, and low-temperature frozen foods. It is set up. Reference numeral 3 designates a cold air forced circulation fan disposed at the upper rear surface of the freezer compartment 1, 4 a cold air outlet for the freezer compartment, and 5 a cold air suction port for the freezer compartment.
Reference numeral 6 denotes a refrigerating room disposed below the ice room 10, and the temperature is controlled to around 5° C. by a refrigerating room damper thermometer 9. 9a is a damper thermostat for the refrigerator compartment. Reference numeral 11 denotes a vegetable compartment, which is arranged at the lower part of the refrigerator compartment 6. 21 is a damper thermometer for the ice room, which controls the temperature of the ice room 18. Reference numeral 21a is a full plate of this damper thermo.

Reference numeral 22 denotes a freezer compartment suction duct, which is a passageway that guides cold air sucked in from the suction port 5 to the cooler compartment. Reference numeral 34 denotes a partition made of a heat insulating material that separates the ice room 10 and the cold room 6, and 23 is an ice room suction port, from which the cold air from the ice room is sucked into the ice room suction formed in the partition 34. It passes through the duct 24 and is led to the cooling chamber 8. Reference numeral 25 denotes a refrigerator compartment suction port opened at the front of the lower surface of the partition 34, and the cold air that has cooled the refrigerator compartment is passed through the refrigerator compartment suction duct 26 formed in the partition 34.
and is sucked into the cooler chamber 8. 27 is cooler 2
This is a defrost heater. In addition, 28 is the blowout duct for the icehouse, with 3 parts of the fan and the damper thermometer 21 for the icehouse.
It is connected to the buff-full portion 21a.

29 is a well-known compressor, 30 is a freezer compartment door, 31 is an ice greenhouse door 32 is a refrigerator compartment door, and 33 is a vegetable compartment door.

In the refrigerator configured in this way, the cold air cooled by the cooler 2 is blown into the freezer compartment 1 from the outlet 4 by the fan 3, and after cooling the freezer compartment, it passes through the suction duct 22 from the suction port 5, and then flows into the cooler. Return to room 8. Further, a part of the cold air cooled by the cooler 2 passes through the icehouse blow-off duct 28 and is blown out to the icehouse 10. The cold air blown into the ice room passes through the suction port 23 and the suction duct 24 and returns to the cooler chamber 8. The other part of the cold air cooled by the cooler 2 is blown out from the refrigerator compartment blow-off duct 7 into the refrigerator compartment 6, cooling the refrigerator compartment, and also cooling the vegetable compartment 11.
It passes through the suction duct 26 and returns to the cooler chamber 8 . Each storage room is controlled by controlling the compressor 29 on and off using the freezing room temperature controller 12 in the freezing room 1, and in the ice room 1.
0 is controlled to an appropriate temperature by a damper thermometer 21 for the ice room, and the temperature of the refrigerator compartment 6 and the vegetable compartment 11 is controlled by a damper thermometer 9 for the refrigerator compartment.

As mentioned above, in this design, the cooler room is provided across the back of the freezer room and ice room, so the freezer room, ice room, refrigerator room, and vegetable room are lined up vertically, and the height is increased from the point of view of ease of use. Even in the case of a freezer compartment that does not have enough space, the cooler size can be made with a margin, which is advantageous in terms of cooling capacity and power saving.Although it is a four-chamber independent refrigerator, the air passage is smaller than the conventional one. 3-door refrigerator Compared to, for example, the refrigerator shown in Utility Model Application Publication No. 55-54874, this refrigerator has the advantage of requiring only one additional cooling air outlet duct, and is easy to develop, inexpensive, and has a high product appeal. can be developed.
