Problems solved by technology

[0015] However, in the above-mentioned conventional structure, since the water is atomized by the ultrasonic vibrating element, the atomized water particles are not fine, so it cannot be uniformly sprayed in the storage, and the adhesion rate of the water mist to the surface of the food is low.
In addition, there is a problem of increasing the spray amount or continuous spraying to increase the adhesion rate, which will cause water rot in vegetables, etc., or condensation in the storage room.
[0016] In addition, in the above-mentioned conventional structure, there are structures that require a defrosting water hose, a purification filter, or a water supply path directly connected to a water supply, and also require a heater for preventing freezing, and the structure is complicated. question
[0017] In addition, in the above-mentioned conventional structure, water mist is sprayed in order to create high humidity in the storage room, but the amount of atomization cannot be adjusted, and water stagnation may occur in the storage room due to excessive spraying, and water rot may occur in storage such as vegetables.

Embodiment approach 1

[0065] figure 1 It is a front view of the refrigerator in Embodiment 1 of this invention, and the figure of the state which removed the door body. Figure 8 It is a longitudinal sectional view of the refrigerator of this embodiment. exist figure 1 , Figure 8 Among them, the refrigerator main body 1 is composed of an outer box 18 and an inner box 19, and is filled with a foam insulation member 20 such as hard foam urethane inside to insulate from the surroundings, and is divided into a plurality of storage rooms. A refrigerating room 21 as the first storage room is set on the uppermost floor, and a switching room 22 as the fourth storage room and an ice-making room 23 as the fifth storage room are arranged side by side in the lower part of the refrigerating room 21. Vegetable compartment 24 serving as a second storage compartment is arranged below ice making compartment 23 , and freezer compartment 25 serving as a third storage compartment is disposed at the lowest portio...

Embodiment approach 2

[0115] Figure 9 It is a longitudinal sectional view of the refrigerator in Embodiment 2 of this invention. Figure 9 , the basic structure is the same as that described in Embodiment 1 figure 1 , Figure 8 same. The same constituent elements are denoted by the same reference numerals. In this embodiment, the lid body 66 is not provided on the upper storage container 65 of the vegetable compartment 24 .

[0116] The operation|movement and effect|action of the refrigerator comprised as mentioned above are demonstrated below. The cold air blown into the refrigerator compartment 21 exchanges heat with the air in the refrigerator compartment 21, is sucked in from the suction port 60 for the refrigerator compartment, and passes through the return air passage 61 for the refrigerator compartment, the return air passage 57 for the refrigerator compartment, and the return air passage for the refrigerator compartment. The wind path 92 returns to the cooling chamber 28 . Here, a p...

Embodiment approach 3

[0123] Figure 5 It is a front view of the refrigerator in Embodiment 3 of this invention, and is the state which removed the door body. Figure 10 It is a longitudinal sectional view of the refrigerator in Embodiment 3 of this invention. exist Figure 5 and Figure 10 , the basic structure is the same as that described in Embodiment 1 figure 1 , Figure 8 same. The same constituent elements are denoted by the same reference numerals. Different from Embodiment 1, the lower end of the sprayer 67 is located above the bottom surface of the upper storage container 65 in a part of the first cooling duct 29 .

[0124] The operation|movement and effect|action of the refrigerator comprised as mentioned above are demonstrated below. Moisture evaporates from the food stored in the lower storage container 64 as time elapses after being put in it. At this time, the air containing evaporated water is discharged from the vegetable compartment through the discharge port 45 and flows...

Abstract

Provided is a refrigerator comprising a mist atomizer disposed in a first cooling duct having a vegetable chamber discharge port and a vegetable chamber suction port. The mist atomizer is arranged inthe vicinity of a clearance between a lower-shelf storing container and an upper-shelf storing container. The refrigerator can recover the water content transpired from stored food, efficiently, and can humidify the inside of the storing container, thereby to keep the freshness at a high level.

Description

technical field [0001] The present invention relates to a refrigerator having a storage compartment maintained in high humidity. Background technique [0002] Factors affecting the decrease in the freshness of vegetables include, for example, temperature, humidity, ambient gas, microorganisms, light, and the like. Vegetables are living things that perform respiration and evaporation. To maintain freshness, respiration and evaporation must be suppressed. Except for some vegetables such as vegetables that cause low temperature disturbance, most vegetables have their respiration suppressed at low temperature, and high humidity prevents evaporation. In recent years, in household refrigerators, in order to preserve vegetables, airtight vegetable containers are installed to cool the vegetables to an appropriate temperature and control them to increase the humidity in the refrigerator to suppress the evaporation of vegetables. In addition, the method of spraying water mist is ado...
