< Structure of ultrasonic vibrator >

Fig. 11a is a schematic view showing a spray element of a refrigerator according to the present invention. Fig. 11b is a cross-sectional view of the spray element shown in fig. 11 a. The humidifying unit of the present invention includes: an ultrasonic transducer 113 capable of vibrating at a predetermined frequency; a metal porous plate 113a provided on the water supply side of the ultrasonic vibrator, and vibrating together with the ultrasonic vibrator to generate spray; and a humidification water tank 111 that can store spray water and bring the spray water into contact with one surface of the metal porous plate 113a. Here, the water supply side of the ultrasonic vibrator means a side of the ultrasonic vibrator where the humidification water tank 111 is located, that is, a side opposite to the spraying direction. The spray water may be tap water, boiled water, mineral water, purified water, or the like, or may be antibacterial water containing an antibacterial and antifungal agent component, or may be a liquid containing a deodorant or aromatic component, or may be a liquid containing a preservative component.

Specifically, the atomizing element 113 of the present invention is, for example, an ultrasonic vibrator (piezoelectric ceramic vibration plate), and as shown in fig. 11, the ultrasonic vibrator 113 is, for example, a circular plate-like member, and a perforated plate 113a having a plurality of micropores is formed in a central portion thereof. Electrodes 113b are formed on the front and rear surfaces of the outer periphery of the porous plate 113a. The electrodes 113b on the front and rear surfaces are supplied with power from the two power supply terminals 115, respectively, so that the ultrasonic vibrator 113 generates ultrasonic vibrations. By this ultrasonic vibration, the water supplied from the water tank 111 to the porous plate 113a is converted into water mist, and the water mist is ejected toward the spray side (the side of the humidification chamber 100) via the plurality of micropores in the porous plate 113a. Thus, the mist can be fed into the humidification chamber 100 without a mist feeding passage, and humidity control can be performed quickly and stably.

The inventors of the present invention have conducted experiments on the relationship between the particle diameter of the mist droplets and the amount of mist and the relationship between the particle diameter of mist and the risk of condensation, and the results are shown in tables 1 and 2.

TABLE 1

Particle size (mum)	Spray quantity (g/min)
		3	0.05-0.1
5	0.3-0.6
		6	0.4-0.8
8	0.6-1.0
		10	0.8-1.5
15	1.0-2.0

TABLE 2

Particle size (mum)	Risk of dewing
		3	Dew formation preventing device
5	Dew formation preventing device
		6	Dew formation preventing device
8	With risk of dewing
		10	Dew formation
15	Dew formation

Although the size of the plurality of micro holes of the porous plate 113a is not particularly limited, it is apparent from the results of tables 1 and 2 that the particle size of the generated mist droplets is preferably 3 to 10 μm, more preferably 4 to 6 μm, and thus the mist is less likely to be condensed on vegetables and fruits, and the vegetables and fruits are prevented from being decayed due to the condensation. In addition, the spray amount may range from 0.2 to 1.5ml/min; the preferred range is 0.4-0.8ml/min.

The size of the spray particle diameter is determined by the pore size of the porous plate, and the larger the pore diameter is, the larger the spray particle diameter is. The number of holes can be adjusted by adjusting the area and the pitch of the porous plate, and thus the amount of spray can be adjusted. And, in the safe voltage range of the circuit board, the higher the voltage is, the larger the spraying amount is, and the farther the spraying distance is.

< Structure of humidifying drawer >

The humidification chamber includes a lid (cover plate) 102 and a humidification drawer 101, and a seal (not shown) is provided between the lid 102 and the humidification drawer 101, and the seal may be made of a material such as rubber. As shown in fig. 12, a wedge shape may be provided on the side wall of the cover plate 102 so as to protrude downward toward the inner side. At this time, the side wall of the humidification drawer 101 is formed in a shape that the height thereof is lowered toward the inner side corresponding to the lower portion of the cover plate 102. By providing the side wall of the cover plate 102 and the side wall of the humidification drawer 101, the internal space of the humidification drawer 101 can be reliably formed as a closed space by pushing the humidification drawer 101 inward. Further, when the humidification drawer 101 is pulled out, the friction force between the upper end of the side wall of the humidification drawer 101 and the sealing member 102a is reduced, so that the humidification drawer 101 can be easily pulled out. The bottom surface of the humidifying drawer 101 may be formed in a concave-convex shape, for example, so that vegetables and fruits can be prevented from being spoiled by contact with water retained on the bottom surface of the humidifying drawer 101.

Fig. 13 is a schematic exploded perspective view showing a humidifying drawer of a refrigerator according to the present invention. The humidifying drawer 101 may have a double-layered structure including an outer case 101a and an inner case 101 b. The outer housing 101a may be drawer-shaped with a slightly larger size than the inner housing 101 b. A hollow heat insulating layer composed of air may be formed between the outer case 101a and the inner case 101 b. Specifically, the outer case 101a and the inner case 101b may be provided with a hollow layer on both the bottom surface and the side surfaces. As shown in fig. 13, a blocking rib 104 extending in the vertical direction is provided around the inner case 101 b. The blocking rib 104 may serve to strengthen the inner case 101b and block the flow of air in the hollow layer. The installation position of the blocking rib 104 is not limited thereto, and may be provided on the housing 101a. The humidification drawer 101 may further include a handle portion 101c located on the front side of the refrigerator. The grip portion 101c may have a hollow heat insulating layer, and a groove portion into which a finger can be inserted may be formed in the bottom portion thereof. Thus, the handle 101c can function as both the push-pull portion and the heat insulating portion.
