Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is capable of preserving various foods at appropriate temperatures.
This relates to temperature-type chilled rhinoceros.

[Prior art]

Figure 1 shows a conventional example shown in, for example, Japanese Utility Model Application Publication No. 55-54874. Freezer room...and refrigerator room (6).

Each vegetable compartment (second refrigerator compartment) 0(a) has its own dedicated door. A water greenhouse (low temperature case) (
1ω is placed. (2) is a cooler that makes up the cooling system. (4) is a fan for forced cold air or α-storage fan. (9) is a damper thermo that controls the temperature inside the cold acid chamber (6).

In a refrigerator configured in this way, the freezer compartment (1) is circulated and cooled by cold air cooled by the cooler (2) or by the fan (3). 4 refrigerator rooms (6), ice room (10), vegetable room (14)
1 is a damper thermo 19), and 6 planes that have been fully controlled are ringed.

Therefore. Refrigerator room (6), low temperature case αq. Vegetable room (14
The temperature of l is determined by Kkj:, which is set in advance in a duct, etc. Rather than each room being controlled independently.

Damper thermostat controlled by the temperature of the refrigerator compartment (6).

All three rooms were under control.

Therefore, from food storage, the special Vc sheath is densely wide.
The low-temperature case (10) that requires ml is also the cold storage room (6)
Depending on the temperature of the refrigerator, if you strongly cool the refrigerator, the low temperature case
) would have been too cold, and on the other hand, if it had been made weaker, it would have been too high.

In the low-temperature case [+1], the temperature fluctuates depending on the opening and closing of the refrigerator door and the operating rate of the outside air temperature compressor, making it impossible to have a tight side corner [1].

[Summary of the invention]

The present invention eliminates the above-mentioned drawbacks and provides a low-cost refrigerator that improves the preservation of food in an ice room by 1%. - It is a refrigerator that can be manufactured and is easy to use.

[Embodiments of the invention]

The present invention will be described below in detail with reference to embodiments.
do.

In Figures 2 and 3, (1) is the freezer compartment, which is installed at the top of the storage compartment of this refrigerator. It can be maintained by controlling people and turning off. (2) is a well-known cooler, and the cold air cooled here is distributed to each storage compartment by a fan (31VC). (4) is a freezer compartment outlet, and (5) is a freezer compartment cold air intake port. 6) is the air duct (7) in the refrigerator room.
Cold air is blown out from the refrigerator compartment through the refrigerator compartment blow-off duct (7a) and controlled by the refrigerator compartment damper thermostat (9). On the other hand, the cold air that has passed through the ice room tact (7b)f is blown out to the ice room 00) through the water temperature damper thermometer +211 and the i+h communication duct (7C). The temperature sensing part (21a) of the damper thermo j7+1 for ice greenhouses is passed through the communication duct (7C).

It is installed in an icehouse (00).

(2'21 is an ice room suction port, which communicates with the refrigerator compartment (6). (14) is a vegetable compartment, which is connected to the ice greenhouse through a vegetable compartment air outlet +231, a vegetable compartment suction port, etc.). Country 0 is the refrigerator compartment suction port. C30) is the freezer compartment door, (31+ is the refrigerator compartment door.In Japan, the icehouse door is equipped with a rail (32a) so that it can be opened and closed in a pull-out manner together with the ice-warming container CM.C33) Similarly, the vegetable compartment door is equipped with a rail (33a) so that it can be opened and closed integrally with the vegetable case (3).

In the refrigerator configured as above, cooling is performed as follows. In other words, the cold air cooled by the 6th prisoner 1 unit (2) is blown out from the freezer compartment air outlet (4) to the cold room (]) by the fan (3), cools the freezer compartment, and then passes through the freezer compartment suction port (5≠・Return to the cooler (2).The temperature of the freezer fi+ is set to the temperature that allows storing frozen stock crystals by controlling the compressor 0!+1 by the temperature controller f2@ for the freezer. Retained.

- 10,000 coolers (2 + 1/()) Some of the cold air is blown out from the blow-off duct (71) to a part of it (or the refrigerator room blow-off tact (7a)) and to the refrigerator room. 6
) After cooling the refrigerator compartment, the cold air blown into the refrigerator compartment returns to the cooler (2+VC) from the refrigerator compartment suction port (25j).
It is kept at 4°C. The cold air that passes through the icehouse blowout tact (7b) from the cold air duct (71) is sent to the damper thermos for the icehouse (which is installed in the refrigerator room next to the damper thermos for the cold room).
21), go through the connecting duct (7C) and enter the icehouse (
It is blown out inside lllj. The cold air blown into the ice room (00) passes through the refrigerator room from the ice room suction port (221) and returns to the cooler. (21a) Ice chamber 0 from VC
Damper Thermo Q for ice greenhouses that senses and controls the temperature inside 0
It is maintained at an appropriate temperature of 0 to -2°C by υ.

In addition, the vegetable compartment 041 takes in a part of the cold air blown into the ice greenhouse QOI from the vegetable compartment air outlet Buddha 3).
After being cooled, it passes through the Noawaken suction port 41, the ice room 00), the refrigerator room (6), and returns to the cooler to be cooled. The dimensions of the outlet and inlet of the vegetable compartment are determined to maintain a temperature of about 5 to 1°C.

〔Effect of the invention〕

As described above, this refrigerator according to the present invention has a freezer compartment,
The cold room, ice room, and vegetable room are arranged from above.

Freezer room, refrigerator room, and ice room each have independent storage space.
The temperature of the cooling room, refrigerator room, and ice room can be precisely controlled by installing a one-direction device.

On the chilled tofu side, which has 4 sheets of Saidasin arranged vertically, the balance of each chamber makes it possible to refrigerate J! ! I can't let L do it. In this case, an ice greenhouse with a height dimension that is not very secure is installed in a pull-out type between the refrigerator compartment and the vegetable compartment.
1 (for example, between the freezer compartment and the refrigerator compartment), it is easier to handle because it is located much below eye level, and by making it a pull-out type, it is easy to put in and take out food even in a small ice room.

In addition, since it comes with a case, there is less cold air loss and temperature rise due to opening and closing the door, and it is effective for storing 14 times a day in a frozen greenhouse.

In addition, these were arranged vertically with VC cooling (floor room, storage room, ice room, and enclosure room) by VC so that 6 shoulders could be installed with one cooler and one fan. 3υ [sludge removal V; The same manufacturing method as for p and tt should be used.

Almost the same equipment can be used for installation, so it can be manufactured at a low cost, and it is also very easy to use! ID Dignified '? It can be one item.

It has a drawer-type lower berth and vegetable compartment (so I had to break my knees), so I don't have to close it or put food in and take it out, so I can provide an excellent refrigerator that is very easy to use.
