Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides dry foods such as seaweed, kelp, tea paste,
This invention relates to a refrigerator equipped with a dry food storage chamber for storing tea, sesame salt, dried fish, rice crackers, rice crackers, etc.

The illustrated embodiment will be described in detail below.

Reference numeral 1 denotes an intermediate partition wall 6 which has a refrigerator body made by injecting and foaming a foamed heat insulating material 4 between an outer box 2 and an inner box 3, and which houses a cooler 5 therein.
The room is divided into two parts, with the upper part serving as a refrigerating compartment 7, and the lower part serving as a dry food storage compartment 8 and a high-temperature storage compartment 9, which will be described later.

A blower fan installed at the rear of the cooler 5 is used to send cold air from the cooler 5 through the cold air passage 11 to the refrigerator compartment 7.
At the same time, the remaining cold air is forcedly blown into the cold air circulation passage 12.

The cold air circulation passage 12 is arranged along the rear and upper outer walls of the inner box 3, and indirectly cools the inside of the inner box 3. 13 is a partition wall that divides the inside of the inner box 3 into upper and lower parts,
A heating device 14 made of a heat insulating material is provided on its upper surface to raise the temperature to 15 to 30 CO.

The heating device 14 is a heater 14 embedded in the partition wall 13.
A (5W to 12W) metal plate 1 with good thermal conductivity on the top surface
4b is attached. Reference numeral 15 denotes a cooler attached to the upper surface of the inner box 3, which is cooled to -150°C by the cold air passing through the cold air circulation passage 12, and is used to dry the upper part defined by the partition wall 13. The food storage compartment 8 is cooled by the cooling device 15 and heated by the heating device 14, and the temperature inside the compartment is 15 to 2 p0.
The humidity is maintained at 40% RH or less.

The reason why the humidity in the dry food storage room 8 can be kept below 40% RH is because the temperature of the air cooler 15 is as low as -150℃ and 10 degrees Celsius, so the green matter in the dry food storage room 8 turns into mist and the humidity is kept in the air cooler 15. 15
This is because the frost adheres to the surface of the vehicle and is melted by a defrosting heater (not shown) and led to the outside. The defrosting water is led out through a drain port 16 at the bottom along the inner wall surface of the inner box 3.
The cooling device 15 itself is provided obliquely on the upper wall of the inner box 3. Reference numeral 17 designates a dry food storage container with an open top that is detachably installed in the dry food storage chamber 8 and is made of a material with relatively good thermal conductivity. silica gel, molecular sieve, etc.) on the synthetic resin fibrous sheet 18b.
The desiccant coating layer 18 sandwiched between the two is integrally formed by thermocompression bonding or adhesive.

In addition, a lid body (
(not shown) is provided so that when the dry food storage container 17 is taken out from the dry food storage chamber 8, the upper opening □ is closed, thereby making it possible to preserve the dry food for a long period of time. Further, by placing the dry food storage container 17 on the heating device 14 in the dry food storage chamber 8, the bottom surface of the food storage container 17 is heated by the heat from the heating device 14, and the desiccant coating layer 18 is heated. The desiccant 18a is automatically regenerated. Reference numeral 19 serves as a guide passage for communicating the dry food storage chamber 8 and the high-temperature storage chamber 9, and is formed on the back side of the high-temperature storage chamber 9. Inside this guide passage 19, another inflator 20 is installed. has been done.

The cooler 20 is attached to the back surface of the inner box 3 and is cooled by the cold air passing through the cold air circulation passage 12. Then, the cold heat from the cooler 20 cools the 15 to 20 oo of air sent from the inside of the dry food storage room 8 to a temperature suitable for storing vegetables. The interior of the high-humidity storage chamber 9 is in a sealed state, and the defrosting water from the cooler 15 flows into the high-temperature storage chamber 9.
Since the humidifying sheet 21 (water absorbing material) provided on the back wall of the
) is held. In addition, 22 is a compressor installed at the bottom of the lower part of the refrigerator body 1, 23 is a main condenser attached to the rear surface of the refrigerator body 1, 24 is an evaporation plate that receives drain water discharged from the drain port 16, and 25 is a An auxiliary condenser is attached to the bottom of the evaporating dish 24, 26 is a door for a refrigerator compartment, 27 is a door for a dry food storage compartment, and 28 is a door for a high temperature storage compartment. Here, the operation of the present invention will be explained.

Now, when the refrigeration cycle is operated, the cold air cooled by the cooler 5 is blown into the cold air passage 11 and the cold air circulation passage 12 by the drive of the blower fan 10.
The cold air passing through 1 is discharged to the refrigerator compartment 7 side, and
The cold air passing through the cold air circulation passage 12 is passed through the coolers 20 and 1.
5. Cool. Thus, while the inside of the dry food storage chamber 8 is cooled by the cooling device 15, the heating device 1 is connected from the bottom thereof.
4 and maintained at an ambient temperature of 15 to 20°C. In addition, the moisture in the dry food storage chamber 8 adheres to the surface of the cooler 15 as frost, and is taken outside during defrosting, so the humidity in the dry food storage chamber 8 is maintained at 40% RH or less. be done. Then, the air inside the dry food storage room is
9 into the high-temperature storage chamber 9, at this time it is cooled by another cooling device 201 in the guide passage 19 and maintained at an ambient temperature of 5±5°C. In addition, the interior of the high-humidity storage chamber 9 is in a sealed state, and the defrosting water from the cooler 15 is hydrated in the heating sheet 21 provided on the back wall of the high-temperature storage chamber 9. Optimal humidity conditions for storage (9
0±5%RH). Since the present invention is constructed as described above, by providing a dry food storage chamber with low humidity, it is possible to provide a completely new function that was not available in conventional refrigerators. It is ideal for storing vegetables, etc., and since the dry food storage room and the high temperature storage room are cooled by the same cold air circuit, the structure is extremely simple and can be manufactured at low cost. It can be effective.
