Fig. 7 is a schematic view showing that the humidifying unit of the refrigerator according to the present invention is held by the cover plate. Fig. 8 is a schematic perspective exploded view showing a case where a humidifying unit of a refrigerator according to the present invention is held by a cover plate. Fig. 9 is a schematic diagram showing pins of an electric device of a humidifying unit of a refrigerator according to the present invention. Fig. 10 is a schematic view of a metal sheet showing a power supply unit of a refrigerator according to the present invention.

As shown in fig. 7 and 8, the humidifying unit 110 is held on one side of the separation layer (cover plate) 102 via a holder 112. The partition layer 102 has a power supply 103 connected to a main circuit board of the refrigerator.

The humidifying unit 103 includes: an electric device 116 for supplying electric power to the atomizing element 113, a holder 112 attached to the separator 102 and holding the humidification water tank 111, and the electric device 116 electrically connected to the electric power supply unit 103 by attaching the humidification water tank 111 to the holder 112. Here, the power supply unit 103 and the electrical device 116 are preferably in electrical contact with each other on the back side of the humidification water tank 111. Further, it is preferable that the power supply portion 103 and the electrical fitting portion 116 make electrical contact on the back surface side of the holder 112.

The holder 112 has a U-shaped cross section when viewed from the front of the refrigerator, and by attaching the humidification water tank 111 to the holder 112, the pin 116a of the electric device portion 116 and the metal plate 103a of the power supply portion 103 are in opposed contact in the left-right direction of the refrigerator. The holder 112 has an opening (not shown) through which the electric device 116 is inserted when viewed from the back of the refrigerator. The width of the opening is preferably 10mm or less, whereby the fingers can be prevented from extending thereinto. Specifically, when the user takes out the humidifying unit 110 and performs water replenishment or washing, the rear surface of the holder 112 can be contacted from the front surface of the refrigerator. On the back surface side of the holder 112, a charged power supply unit 103 is further provided. Here, the power supply unit 103 is provided on the separator 102, for example. By setting the opening on the back surface of the holder 112 to 10mm or less, the user can be prevented from touching the power supply unit 103 by hand.

< 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.

Preferably, the evaporator 11 and the humidification chamber 100 do not overlap, i.e., do not have an overlapping portion, as viewed from the front-rear direction of the refrigerator. Preferably, the evaporator 11 is disposed above the humidification chamber 100.

By providing the evaporator 11 and the return air inlet 12 above the humidification chamber 100, the cool air circuit can bypass the humidification chamber 100, and the problem of dew condensation in the humidification chamber 100 can be avoided. In the example shown in fig. 13, the return air inlet 12 at the bottom extends in the left-right direction of the refrigerator so as to cover substantially the entire width direction, but the present invention is not limited thereto, and the return air inlet 12 at the bottom may be divided into left and right portions, each extending in the width direction of the refrigerator.

In addition, as shown in fig. 13, the return air inlet 12 may be further disposed at a corner of the refrigerating space, so as to further increase the return air area.

And because the humidifying device is powered off immediately after being taken down, the electricity utilization safety of a user is ensured.

According to the refrigerator in one aspect of the invention, the cold air circulation flow path passing through the evaporator bypasses the humidifying chamber through the transformation of the air path, so that the problem of dew condensation in the humidifying chamber is avoided.

According to the refrigerator in one aspect of the invention, the humidifying drawer adopts a double-layer heat insulation structure, and the humidifying drawer is isolated from the surrounding refrigerating space through the heat insulation layer, so that cold air in the refrigerating space is prevented from entering the humidifying chamber, and the problem of dew condensation in the humidifying chamber is avoided. In addition, the humidifying drawer is sealed with the cover body through the sealing layer, so that the sealing effect in the humidifying chamber is further improved, and the temperature and humidity control effect in the humidifying chamber is ensured.

According to the refrigerator in one aspect of the invention, the temperature and humidity in the humidifying chamber can be controlled in a wider range through the humidifying device and the temperature compensating device, so that a user can store various foods and drinks.

In the description of the above embodiment, only specific examples are given, and the structures, connection manners of the components and the like are not limited thereto, and all equivalent changes and modifications performed on the basis of the technical solution of the present invention should not be excluded from the protection scope of the present invention.
