An overflow portion 56a is formed at a front end portion of the rear side of the water storage container 56, and a height direction of the overflow portion 56a is lower than a wall portion for forming a water storage container 56.

Thereby, when the water accumulated in the water storage container 56 overflows, the water overflows from the overflow portion 56a. The water overflowing from the overflow portion 56a is received by the drain pipe 40 and discharged to the defrosting water evaporation tray 28.

The mist discharge portion 50 is provided in the horizontal portion 53a of the water supply portion 53. The mist releasing portion 50 is a lower rear portion of the refrigerating chamber 3, and is located at an upper rear portion of the vegetable compartment 4 and behind the freezing compartment 14, and is constituted by a plurality of mist releasing pins 57 forming a projection for releasing the mist.

In this case, the four mist release pins 57 are arranged side by side in the horizontal direction. In addition, the other plurality of mist release pins 57 are arranged to protrude downward on the lower side of the horizontal portion 53a. In this case, the four mist release pins 57 are arranged side by side in the horizontal direction.

In other words, the mist releasing portion 50 is formed in a different direction, and in this case, a plurality of mist releasing pins (protrusions) 57 projecting upward and downward. Further, the mist releasing portion 50 is disposed such that the plurality of mist releasing pins 57 extend in the opposite direction of the horizontal portion 53a of the water supply portion 53 in the upward and downward directions.

Further, the plurality of mist discharge pins 57 are arranged in two stages. Each of the mist discharge pins 57 is disposed in parallel with the front wall 36a of the refrigerating cooler chamber 36 of the cold air duct 34. The mist releasing portion 50 is provided at a position below the lower portion of the refrigerating chamber 3 and adjacent to the vegetable compartment 4, and is disposed at the rear of the freezing compartment 14.

Each of the mist discharge pins 57 is a portion that generates mist as described above. For example, the polyester fiber and the carbon fiber of the conductive material are mixed and woven to form a pin shape (rod shape), thereby having water retention and water absorption characteristics, and having conductivity. Sex.

Each of the mist discharge pins 57 carries a Platinum Nano Colloid. For example, the nano platinum colloid may be carried by immersing the mist release pin 57 in a treatment liquid containing a nano platinum colloid and calcining it.

The base end portion of each of the mist discharge pins 57 penetrates the case 54 of the water supply portion 53 and comes into contact with the water retaining material 55. In the left end portion of the horizontal portion 53a of the water supply portion 53, a power receiving pin 58 that constitutes an electrode for power receiving is provided to protrude leftward. The base end portion of the power receiving pin 58 is in contact with the water retaining material 55 in the case 54.

The power supply device 52 is located in the mist generating chamber 45 on the left side of the mist generating unit 51 and is in a fixed state. A power supply terminal 61 composed of a fast-on terminal is connected to the wire 60 at the right end of the power supply device 52, and the power supply terminal 61 is connected to the power receiving pin 58 of the mist generating unit 51. As is well known, the power supply unit 52 includes a rectification circuit including a high voltage transformer that converts a high frequency power source (alternating current source) into a direct current, a booster circuit, and the like, and generates a negative high voltage (for example, -6 kV) via the power supply terminal 61. And output to the power receiving pin 58.

Thereby, the negative high voltage from the power supply device 52 is applied from the power receiving pin 58 to the respective mist discharge pins 57 via the moisture of the water retaining material 55, so that the respective mist discharge pins 57 are negatively charged. Further, in this case, the outer casing 2a of the refrigerator body 1 is grounded via a grounding wire (not shown) or the like.

In the electrostatic atomizing device 48 configured as described above, the water in the water storage container 56 is extracted by the capillary phenomenon of the water retaining material 55 and supplied to the respective mist discharge pins 57, and the respective mist discharge pins 57 are applied from the power supply device 52. Negative high voltage.

At this time, the electric charge is concentrated on the tip end portion of each of the mist discharge pins 57, and the water contained in the tip end portion is given energy exceeding the surface tension, thereby splitting the water at the tip end portion of each of the mist release pins 57 (Rayleigh splitting) Rayleigh fission), which is released from the tip end portion in a fine mist (electrostatic atomization phenomenon).

Here, the water particles discharged in a mist form are negatively charged and contain a hydroxyl radical generated by the energy.

Therefore, the hydroxyl radical having a strong oxidizing action is released together with the mist from the respective mist releasing pins 57, and can be sterilized or deodorized by the action of the hydroxyl radical. In this case, a counter electrode corresponding to the negatively-charged mist discharge pin 57 is not provided.

Therefore, the discharge from the mist discharge pin 57 itself is very stable, and no corona discharge occurs between the discharge electrode and the counter electrode, and harmful gases (ozone or nitrogen generated by oxidation of nitrogen in the air by ozone can be suppressed). Production of oxides, nitrous acid, nitric acid, etc.).

Here, the mist release pin 57 (the mist discharge portion 50) can be a sterilization component discharge mechanism (also a deodorization component discharge mechanism) that releases a sterilization component (also a deodorization component) called a hydroxyl radical, and electrostatic discharge The atomizing device 48 can be used as a sterilization component generating mechanism (deodorizing component generating mechanism).

Next, the mist generating chamber 45 will be described in detail.

The mist generating chamber 45 accommodates the mist generating unit 51 as described above. Thereby, the mist generated by the driving of the mist generating unit 51 is likely to accumulate in the mist generating chamber 45.

Therefore, even when the density unevenness occurs due to the passage of time or the like in the mist generated by the mist generating unit 51, the generated mist is diffused in the mist generating chamber 45, so the concentration of the mist in the mist generating chamber 45 is liable to change. It is roughly uniform.

The mist generating chamber 45 is provided with a wind supply port 62 in the front wall 36a of the refrigerating cooler chamber 36 constituting the rear wall (see FIGS. 4 and 7). The air supply port 62 is an opening for sucking a part of the wind (cold air) that has passed through the refrigerating cooler chamber 36, which is generated by the air blower of the refrigerating blower fan 35, into the mist generating chamber 45.

Therefore, the mist generated by the mist generating unit 51 in the mist generating chamber 45 is convected by the wind sucked from the wind supply port 62, and is easily diffused. Thereby, the concentration of the mist in the mist generating chamber 45 is likely to become more uniform.

Further, a part of the mist convected in the mist generating chamber 45 passes through the mist blowing port 64, the mist duct 63 leading to the refrigerating chamber, and the cold air supply duct 37 together with a part of the wind sucked from the air supply port 62.

Therefore, a part of the wind passing through the refrigerating cooler chamber 36, that is, a part of the cold air, is directly supplied to the freezing compartment 14 through the freezer compartment air supply duct 68 (from the arrow A2 of FIGS. 4, 6, and 8). Indicates the flow of wind). Further, the heat insulating material 38 also serves as an insulating mechanism between the refrigerating cooler 24 and the mist discharge portion 50.

Next, the action of the refrigerator including the configuration of the mist generating mechanism will be described.

When the refrigerating compartment 3 and the vegetable compartment 4 are cooled, the cold air cooled by the refrigerating cooler 24 is used by the air blown by the refrigerating blower fan 35, as shown by the hollow arrow in Fig. 1, and is supplied by the cold air. The air duct 37 is supplied to the refrigerating compartment 3 from a plurality of cold air supply ports 39.

In addition, a part of the wind generated by the refrigerating air supply fan 35 is directly supplied to the freezing compartment 14 from the freezer air supply duct 68 (see arrows A2 in FIGS. 4, 6, and 8). The cold air supplied to the refrigerating compartment 3 and the freezing compartment 14 is merged after the storage of the food or the like is cooled, and is also supplied to the vegetable compartment 4 from the communication port 44 (see FIG. 5).

After cooling the storage of the vegetable or the like, the cold air supplied to the vegetable compartment 4 is sucked from the suction port 43 to the side of the refrigerating blower fan 35, and the cycle of cooling by the refrigerating cooler 24 is repeated again.

When the refrigerating compartment 3 and the vegetable compartment 4 are cooled, a part of the wind passing through the refrigerating cooler chamber 36 is sucked from the wind supply port 62 and supplied into the mist generating chamber 45 as indicated by an arrow A1 in FIG. Here, the mist blowing ports 64, 65, 66, 67 are provided at positions that do not directly face the wind supply port 62, and thus the wind sucked from the wind supply port 62 hits the inner peripheral wall of the mist generating chamber 45 (the duct constituent member 46). The rear side is changed in the direction, and the air taken in from the air supply port 62 is blown out from the respective air outlets of the mist blowing ports 64, 65, 66, and 67.

At this time, when the electrostatic atomizing device 48 is driven, a fine mist containing hydroxyl radicals as described above is discharged from each of the plurality of mist discharge pins 57 of the mist generating unit 51. The released mist is accumulated in the mist generating chamber 45 and diffused into the mist generating chamber, so that the concentration of the mist in the mist generating chamber 45 becomes substantially uniform.

The wind supply port 62 and the mist discharge portion 50 (the mist discharge pin 57) are disposed at positions different from each other, and thus the wind (cooling air) sucked into the mist generation chamber 45 from the wind supply port 62 is not directly It is in contact with the mist releasing portion 50 (the mist releasing pin 57). Thereby, the phenomenon that the mist discharge pin 57 directly receives the cooling air from the wind supply port 62 to be dried and frozen can be suppressed.

The electrostatic atomizing device 48 constituting the mist generating device includes a mist releasing portion 50 that emits mist, a water supplying portion 53 that supplies moisture to the mist releasing portion 50, and a power source device 52 that applies a negative voltage to the mist releasing portion 50, and A plurality of mist discharge pins (protrusions) 57 protruding in different directions constitute the mist discharge portion 50.

According to this configuration, unlike the case where the protruding direction of the projection for generating mist is only one direction, the supply direction of the mist can be made to be plural directions, and thus the supply range of the mist can be enlarged.

The mist releasing portion 50 is configured such that the mist releasing pin 57 extends upward and downward in the opposite direction across the horizontal portion 53a of the water supply portion 53, so that mist can be released both upward and downward, and the supply range of the mist can be enlarged.

Further, a plurality of storage chambers are provided in the vertical direction, and the mist generating chambers 45 are configured to have the mist blowing ports 64, 65, 66, and 67 corresponding to the respective storage chambers, so that the respective storage chambers and the mist discharge pins 57 can be shortened as much as possible.

The water supply unit 53 has a bent portion 53c, and a water storage container 56 that stores water is provided below the bent portion 53c, and is configured to supply water accumulated in the water storage container 56 to the bent portion 53c.

Thereby, the water of the water storage container 56 can be supplied to the mist discharge pin 57 via the bending part 53c. Further, since the mist discharge pin 57 can be separated from the water storage container 56, the mist discharge pin 57 can be insulated from the water in the water storage container 56.

The power supply device 52 is disposed on the opposite side of the bent portion 53c via the mist discharge portion 50. Thereby, the power supply device 52 can be further separated from the water storage container 56.
