Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a refrigerator, and more particularly to a refrigerator equipped with a humidifier and suitable for preserving fresh foods.

b. Conventional technology Figure 1 is a sectional view showing an example of a conventional refrigerator, in which the insulation box/ is an outer box and an inner box J located inside the outer box.
and a heat insulating material filled between the inner box J and the outer box J. A heat insulating door S that can be opened and closed is provided on the front of the heat insulating box. A cooling system comprising a compressor, a condenser 1), a condensing fan motor, etc., which constitute a refrigeration circuit, is provided in the machine room lj provided on the upper surface of the heat insulating box.

A three-tier shelf net ta is arranged in the refrigerator compartment D, which is the internal space of the heat-insulating box 1. A duct IO is defined at the rear of the refrigerator compartment 9.

The 10K is equipped with an evaporator connected to a condenser. Above the evaporator, there is a cooling fan 1.
3 is provided 1) to generate forced circulation convection inside the refrigerator compartment. A humidifier saw is provided below the evaporator/l.

The humidifier saw is usually an ultrasonic type, a centrifugal force type, or a high-pressure spray set. The interior maintains high relative humidity values. In the case of a normal refrigerator, the relative humidity in the refrigerator compartment decreases due to the dehumidifying action of the evaporator due to heat absorption (1), and as a result, water evaporates from the surface of fresh foods with high moisture content, reducing their freshness. I fall.

This humidifier saw is provided to prevent the above-mentioned inconvenience.

By the way, in the refrigerator with the above configuration, water is sprayed into the refrigerator compartment from the humidifier saw, so countless fine water droplets are scattered inside the refrigerator compartment, and these water droplets adhere to the surface of the food and cause it to solidify. It becomes K to do. As a result, food quality deteriorates due to discoloration, and this tendency is particularly strong for fresh foods such as meat and fish.

C1 Problems to be Solved by the Invention As mentioned above, in conventional refrigerators, there is a problem in that the quality of food stored in the refrigerator compartment deteriorates due to discoloration due to solidification of water droplets during refrigerated storage. Ta.

Means for the d0 invention to solve the problem The refrigerator of this invention is Ig warabi 24, co! , 32.

The walls around 3J are made of waterproof/breathable material.

89 Effect In this invention, the moisture containing countless water droplets sprayed from the humidifier saw is sent to the refrigerator compartments 24, 25, along with the cold air.
32, 32 collides with wall surface /9 that constitutes. Wall/
? Among the moisture and cold air that collided with the refrigerator compartments 24 and 25, the water vapor and cold air pass through the wall surface 19, but the water droplets are caught on the wall surface 19.

You cannot invade inside 32 here. As a result, the refrigerator room costs $2! , Here, the atmosphere inside 32 is low temperature and high humidity.

f. Example Hereinafter, an example of the refrigerator of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing a second embodiment of the invention;
The figure is an exploded perspective view of FIG. 1, and the same or corresponding parts as in the first figure are denoted by the same reference numerals, and the explanation thereof will be omitted. The front of the inner box J has openings at the top and bottom/6. A support frame/l with a diameter is attached. Each opening #, /7 has a wall surface made of waterproof/breathable material (for example, registered trademark Voretex) that is both waterproof and breathable. The body of the refrigerating box that defines the refrigerating compartments 24 and 25 is large. Each roller is fixed.

The refrigerated box is rich. Inside the roller is a refrigerated box. A reinforcing frame is attached to reinforce the roller. Reinforcement frame
A wedge-shaped locking portion J is formed on the support rod. A shelf net /l is removably provided on this locking portion J.

Next, the operation of the refrigerator configured as described above will be explained. With the operation of the compressor 6, the refrigerant in the refrigeration circuit is
The refrigerant is transported from the compressor 6 to the condenser, and the refrigerant condensed there is evaporated by removing latent heat of vaporization from the outside air in the evaporator, and then returned to the compressor 4. The air in the duct IO cooled by the evaporation of the refrigerant and the moisture sprayed from the humidifier saw are forcibly sent toward the refrigerator compartment 25 as the cooling fan/J rotates, and It will collide with l. At that time, the wall surface it, whose surface has a microporous structure of 0.2 to J .mu.m, allows cold air and water vapor to pass through, but water droplets are captured by the wall surface /9. Therefore, the refrigerator compartment 24, Ko! The inside of the refrigerator compartment 2 is cooled by cold air and humidified by water vapor.
The atmosphere inside 4 and 25 is low temperature and high humidity 1), making it an ideal condition for refrigerated storage of fresh foods. Furthermore, since the space inside the refrigerator compartments 24 and 25 is in contact with the space inside the insulating box l through the wall surface 19, it is compared with the space inside the insulating box l, which directly receives the cold air from the evaporator. Therefore, the range of temperature change is small (1), which provides good conditions for refrigerated storage. Note that the water droplets caught on the wall surface 19 are discharged to the outside of the heat insulating box l through a drain pipe (not shown).

FIG. 3 is a sectional view showing a second embodiment of the present invention. The refrigerating box core, J, is fixed to a support frame 9 attached slightly inside from the front surface of the heat insulating box l. There is an inner door J on the front of each of the refrigerator box cores, -g.
O, J/ are attached so that they can be opened and closed. Therefore, the refrigerator compartment 32.

When taking out the refrigerated items in 32, it is only necessary to open one of the inner H3o and Jt where the refrigerated items are stored, so the temperature rise and the humidity drop in the atmosphere inside 25 can be suppressed. I can do it.

In addition, there is a low temperature between the insulation door 3 and the inner door JO, J/.
Since this serves as a circulation path for high-humidity air, air convection within the heat-insulating box 1 becomes active, and the interiors of the refrigerator compartments 32, 32 are efficiently brought into a low-temperature, high-humidity atmosphere.

Although the second and second embodiments have been described with an evaporator/l and a humidifying device installed inside the heat insulating box, the present invention is not limited to this, and the evaporator and humidifying device can be installed inside the heat insulating box. It may be arranged outside the heat insulating box l via a duct. In addition, refrigerator compartments 24, 25, 32, 32
The number of is not limited to two, but may be - or three or more. Furthermore, the present invention can also be applied to a prefabricated large refrigerator that is easily manufactured.

g8 As described in detail of the invention, according to the refrigerator of this invention, the refrigerator compartment 2
4. Ko! , 32, 32 has a low temperature and high humidity atmosphere 1), which has the effect of providing good refrigerated storage conditions for fresh foods such as meat and fish.
