Description

[Detailed explanation of the invention] This invention relates to a refrigerator in which a freezer compartment, an ice room, a refrigerator compartment, and a vegetable compartment are arranged sequentially from the top, and each compartment has a dedicated door. This is what we are trying to provide. Conventionally, as in Utility Model No. 55-54874, a freezer compartment,
Various cooling systems have been proposed for 3-door refrigerators with a refrigerator compartment and vegetable compartment placed sequentially from the top, but most proposals have not been made for 4-door refrigerators with a freezer compartment, ice chamber, refrigerator compartment, and vegetable compartment placed sequentially from the top. It has not been.

This invention aims to provide an easy-to-use four-door refrigerator, and this invention will be explained in detail below with reference to FIGS. 1 to 3.

1 is controlled by turning on/off the compressor 29 using the freezer room temperature controller 12 to maintain the temperature at which frozen foods can be stored in the freezer room.

2 is a cooler and the cold air cooled here is sent to fan 3
distributed to each room. 4 is the freezer compartment outlet, 5
6 is a suction port, and 6 is a refrigerator room whose temperature is controlled to around +5°C. 7 is a refrigerator compartment air duct that guides the cold air cooled by the cooler 2 to the refrigerator compartment 6; 8 is a cooler compartment that stores the cooler; 9 is a damper thermometer for the refrigerator compartment that controls the temperature of the refrigerator compartment; That's a big deal. 10 is an ice chamber that is normally maintained at a temperature of around 0 degrees Celsius, and is used to preserve foods such as meat and fish that are suitable for storage at around 0 degrees Celsius, but this ice chamber has the smallest internal volume among the four rooms, and will be explained later. It is also possible to switch to the freezer compartment using the following method. 11 is a vegetable room. 2
1 is a damper thermometer for ice greenhouses, which normally replaces 10 in ice greenhouses with 0.
℃, but by setting the adjustment dial 21b to the highest temperature, the temperature can be controlled to, for example, below -12℃ so that the ice room can also be used as a freezing room. 21a is its full size. 22 is a freezing room suction duct, 23 is an ice room suction port, 24 is an ice room suction duct, 25 is a refrigerator room suction port, 26 is a refrigerator suction duct, and 28 is an ice room blowout duct, each of which constitutes a cold air circulation path. ing.
27 is the defrost heater of the cooler, 30 is the freezer compartment door, 3
1 is an ice greenhouse door, 32 is a refrigerator door, and 33 is a vegetable compartment door.

Each compartment of the refrigerator configured as described above is cooled as follows. Most of the cold air cooled in the cooler compartment 8 by the cooler 2 is normally blown out from the freezer compartment outlet 4 by the fan 3, and after cooling the freezer compartment 1, is sucked in from the freezer compartment suction port 5 and then passed through the freezer compartment suction duct. 22 and returns to the cooler chamber 8. The temperature inside the freezing compartment 1 is controlled by controlling the compressor 29 to turn on and off using the freezing compartment temperature regulator 12. On the other hand, a part of the cold air cooled by the cooler is blown out into the icehouse 10 from the icehouse blow-off duct 28, cools the inside of the icehouse 10, and then passes through the icehouse suction port 23 and the icehouse suction duct 2.
4 and back to the cooler chamber 8.
The temperature of the icehouse is controlled by a damper thermometer 21 for the icehouse. This ice room has the smallest volume of the four rooms, and is located between two cooled rooms: a freezing room on the top and a refrigerator room on the bottom, so the load required for cooling is extremely small. Therefore, even if the volume of air blown from the icehouse duct 28 is not as large as the volume of air blown into the freezing chamber 1 above, it is possible to cool the ice to a temperature range where freezing is relatively easy, for example, below -12°C. At this time, the ice greenhouse damper thermo 21 is set to control the inside of the ice greenhouse 10 to the freezing room temperature at the strongest position of the dial 21b.
The icehouse can also be used as a freezing room. In addition, a part of the cold air cooled by the cooler 2 is blown out from the refrigerator compartment air duct 7 to cool the refrigerator compartment 6 and the vegetable compartment 11, and after cooling the refrigerator compartment and the vegetable compartment, a part of the cold air is blown out from the refrigerator compartment suction port 25. It returns to the cooler chamber 8 via the suction duct 26. Additionally, the temperature of the refrigerator compartment and vegetable compartment is controlled to a constant temperature by a damper thermometer for the refrigerator compartment.

In addition, when switching the ice room 10 as a freezing room, although the load is small, the distribution of air volume to each room changes, but since the total air volume of the fan 3 is the same, the ice room 10 is set to the freezing temperature. By switching, the air volume to the refrigerator room will decrease, and conversely, the air volume to the ice room will decrease
When switching from freezing temperature to ice temperature, the air volume to the refrigerator compartment decreases, but as mentioned above, the refrigerator compartment 6 and vegetable compartment 11 are controlled to a constant temperature by the refrigerator damper thermometer 9, and the freezer compartment 3 is compressed. The temperature is controlled by turning on and off the machine 29.

As mentioned above, this refrigerator is divided vertically into four levels from the top, including a freezer compartment, an ice room, a refrigerator compartment, and a vegetable compartment. In addition to being able to store at a certain temperature, the ice room 10 can also be used as a freezing room, making it convenient for users who want to use the freezer more widely. The cooling load on the ice room is small because it is installed between the freezer and the refrigerator, and it can be cooled down to a temperature that can be used as a freezer without increasing the air volume. Since switching can be performed simply by setting the characteristics of the damper thermostat without the need for a special switching device, it is possible to provide a refrigerator that is very inexpensive, easy to use, and has a high product appeal.

Claims (1)

[Scope of utility model registration request] In a four-door refrigerator, the freezer compartment, ice room, refrigerator compartment, and vegetable compartment are arranged sequentially from the top, and each compartment has its own door.The capacity of the ice room is the smallest among the four rooms, and the temperature is controlled only by a damper thermometer. At the same time, the damper thermostat's adjustment dial is set at the highest position to a temperature that can be used as a freezer compartment, and the refrigerator compartment and vegetable compartment are controlled by separate damper thermoses.
