In the present embodiment, the mist releasing portion 49 is formed by, for example, mixing a polyester fiber and a carbon fiber as a conductive material to form a pin shape, and arranging the pin-shaped releasing members in a plurality of rows, and having the same shape as the water absorbing pin 48. The water retention property and the moisture absorption property are the same as those of the conductive sheet 46. The front end of the mist release portion 49 is formed into a curved shape in which the tip end is made thinner and has a moderate circle.

A Colloidal platinum was attached to the mist release portion 49. The nano platinum fine particle colloid is, for example, immersed in the mist release portion 49 into a treatment liquid containing the colloid of the nano platinum fine particles, and can be attached by calcination. Each of the mist release portions 49 is in contact with the conductive sheet 46 at its upper end portion.

Moreover, the lower end portion of the mist release portion 49 protrudes in a state of penetrating the lower portion of the upper case 44 so as to penetrate the upper case 44. The upper cover 44 release portion cover 50 is detachably provided to cover the mist release portion 49.

A release port 51 located below the mist release portion 49 is formed in the release portion cover 50. A mist discharge port 52 located at the rear of the discharge port 51 is formed in the bottom plate 37.

The mist release port 52 communicates with the upper portion in the vegetable compartment 4. The discharge port 51 communicates with the mist release port 52, and when the mist is released from the mist release portion 49, the mist is formed as indicated by an arrow A in FIG. 6, and is supplied from the discharge port 51 to the vegetable compartment 4 through the mist release port 52. Inside.

Here, the water absorbing pin 48 sucks up the water W in the water storage tank 43 and supplies it to the water retaining material 47 and the conductive sheet 46. The water retaining material 47 holds the water supplied from the water absorbing pin 48 and supplies the water to the conductive sheet 46.

The conductive sheet 46 is supplied with water supplied from the water absorbing pin 48 and the water retaining material 47 to the mist releasing portion 49.

When a negative high voltage of the DC high-voltage power supply device 56 is applied to each of the mist release portions 49, the current concentrates on the tip end portion of the mist discharge portion 49 which is most easily discharged.

As a result, a natural discharge phenomenon occurs in each of the mist release portions 49, and the ion wind generated by the discharge action causes the moisture split on the surface of the mist release portion 49 to be released into a fine mist.

As described above, the electrostatic atomizing device 36 does not have the counter electrode with respect to the mist releasing portion 49. Therefore, since ozone does not occur, the released mist does not contain ozone.

The water injection cover 68 that opens and closes the water injection port 67 in the unit cover 45 is detachably attached, and the water supply port 68 can be refilled with water from the water injection port 67 in a state where the water injection cover 68 is removed.

Further, a photocatalyst 69 made of, for example, titanium oxide is applied to the inner surface of the water storage tank 43. A light source (for example, an ultraviolet LED) 70 that emits ultraviolet light is provided at the bottom of the unit housing portion 41. When the light source 70 is turned on, ultraviolet rays are irradiated to the water storage tank 43, and the photocatalyst 69 receives the ultraviolet rays to be activated, and exhibits a sterilization action.

As shown in FIG. 1, the vegetable and fruit compartment 4 is provided with a lower container 72 and an upper container 73 disposed at an upper portion of the lower container 72. The upper container 73 is formed smaller than the lower container 72 in the front-rear direction, and is disposed on the rear side of the lower container 72.

The front end portion of the upper container 73 is positioned below the mist release port 52 of the bottom plate 37. Further, in this state, when the mist is released from the mist release port 52 into the fruit and vegetable compartment 4, the mist is supplied to both the lower container 72 and the upper container 73 (see Fig. 6).

A control device 75 containing a microcomputer is provided on the back of the refrigerator body 1 (see Fig. 1). The control device 75 is configured to include a compressor 19, a refrigerating fan 14, a freezing fan 17, an automatic ice making device 12, a water supply mechanism 29, a pump motor 30, an electrostatic atomizing device 36, a light source 70, and the like that are controlled to be a refrigeration cycle. A means of controlling the function of the overall operation of the refrigerator body 1.

The control device 75 is particularly constituted by the electrostatic atomizing device 36, and only the door switch of each storage compartment detects the locking of the door, and the cover switch 62 of the electrostatic atomizing device 36 detects the locking of the cover 40, and the unit detecting switch 61 When the installation state of the atomization unit 38 is detected, the energization of the electrostatic atomization device 36 is permitted.

Therefore, when it is detected that the door of any one of the storage compartments is opened, or the case 40 is opened, or the atomization unit 38 is not installed, the energization of the electrostatic atomization device 36 is cut off. Further, the control device 75 causes the light source 70 to perform lighting control for a predetermined period of time every predetermined time.

Explain the role of the above construction.

The atomizing unit 38 is attached to the unit accommodating portion 41, the lid 40 of the unit accommodating portion 41 is closed, and when the electrostatic atomizing device 36 is driven in a state where the doors of the respective storage chambers are locked, the mist releasing portion 49 is released. The mist is finely supplied, and the mist is supplied from the mist discharge port 52 to the upper container 73 and the lower container 72 of the vegetable compartment 4.

The mist contains a hydroxyl radical having a strong oxidizing action, and a mist containing a hydroxyl radical thereof is supplied to the upper container 73 and the lower container 72 of the vegetable compartment 4 to make such sterilization or deodorization possible. .

Moreover, the freshness of the fruits and vegetables accommodated in the upper container 73 and the lower container 72 can be expected by the mist. Further, by causing the light source 70 to perform lighting control for a predetermined period of time every predetermined time, the photocatalyst 69 in the water storage tank 43 is activated, and the sterilization action in the water storage tank 43 can be expected.

However, since the electrostatic atomizing device 36 does not have water, mist cannot be generated, so it is necessary to periodically supply water. In addition, when the dirt adheres to the surface of the mist release portion 49, the release performance of the mist is lowered. Therefore, for example, once a year or so, it is preferable to perform the cleaning of the mist release portion 49.

In this case, after opening the door 3a of the refrigerating compartment 3, the cover 40 of the front portion 8a of the partition plate 8 is slid, and the opening portion 39 of the unit accommodating portion 41 is opened. Then, the user inserts the hand into the unit accommodating portion 41, slides the atomizing unit 38 holding the electrostatic atomizing device 36 forward, and then picks up it and takes it out from the unit accommodating portion 41. At this time, the connection of the connector 58 to the power supply pin 54 is detached.

When only water supply is performed, water is supplied from the water injection port 67 in a state where the water injection cover 68 is removed. When the mist release portion 49 is also cleaned, the upper casing 44 is detached from the water storage tank 43, and the release portion cover 50 is removed from the upper casing 44, and the mist release portion 49 is exposed to be cleaned.

Further, when only the water supply is performed, the atomization unit 38 can be attached to the unit housing portion 41 by removing only the water injection cover 68.

Further, after the supply or cleaning of the water is completed, the atomizing unit 38 is attached in the original state, and then the atomizing unit 38 is housed in the unit housing portion 41 and attached to a normal position. At this time, the power supply pin 54 is inserted and connected to the connector 58. After that, the cover 40 is slid forward to close the opening 39, and the door 3a of the refrigerating compartment 3 is closed.

According to the first embodiment described above, the following operational effects can be obtained.

The partitioning plate 8 between the refrigerating compartment 3 and the vegetable and fruit compartment 4 is provided with an electrostatic atomizing device 36 of a structure which does not generate ozone, and is made into a mist which is released from the mist releasing portion 49 of the electrostatic atomizing device 36 thereof. Mainly supplied to the structure of the vegetable and fruit chamber 4. According to this, the mist containing the hydroxyl radical having a strong oxidizing action is supplied into the vegetable compartment 4, and the sterilization or deodorization in the vegetable compartment 4 is made possible. Moreover, it is also expected that the freshness of fruits and vegetables, etc. can be maintained by the mist.

Since the electrostatic atomizing device 36 is not provided with the counter electrode of the mist releasing portion 49, unlike the conventional structure in which corona discharge occurs between the mist releasing portion and the counter electrode, generation of harmful gases such as ozone can be suppressed. Improve safety.

The electrostatic atomizing device 36 has a water storage tank 43 that stores water W, and constitutes the water W stored in the water storage tank 43 via the water absorbing pin 48, the water retaining material 47, and the conductive sheet 46, and supplies the water W to the respective mist releasing portions 49. Thereby, since the water can be stably supplied to the mist release portion 49, the amount of mist generated from the mist release portion 49 can be stabilized.

Further, since the water storage tank 43 can detach the unit accommodating portion 41 from the entire atomization unit 38, the water in the water storage tank 43 can be easily replenished. Since the mist release portion 49 can be attached and detached together with the water storage tank 43, the cleaning of the mist release portion 49 can be easily performed.

Since the filter filter 65 is provided in the water storage tank 43, the water supplied to the water storage tank 43 can be purified, and the clean water can be supplied to the mist release portion 49. Thereby, it is possible to prevent the occurrence of clogging of the mist release portion 49 and the like as much as possible, and it is possible to prevent the amount of release of the mist from being lowered.

Further, since the ion exchange resin 66 is accommodated in the filter filter 65, the mineral component contained in the water W stored in the water storage tank 43 can be adsorbed to the ion exchange resin 66 and removed.

Thereby, it is possible to prevent the rust from accumulating in the mist discharge portion 49 or the like as much as possible, and it is possible to prevent the occurrence of clogging, and it is possible to further prevent the decrease in the amount of mist released. By this, the life of the mist release portion 49 can be made long.

In addition, the photocatalyst 69 in the water storage tank 43 is activated by the light source 70 for a predetermined period of time to control the light source 70 for a predetermined period of time, and the sterilization action in the water storage tank 43 can be expected. Even in this manner, clean water can be supplied to the mist release portion 49.

Since the atomizing unit 38 of the electrostatic atomizing device 36 is disposed in the front portion 8a of the partition plate 8, the supply of water to the atomizing unit 38 or the atomizing unit 38 can be easily attached or detached. Since the mist released from the mist releasing portion 49 of the atomizing unit 38 is supplied from the upper side to both the upper container 73 and the lower container 72 of the vegetable compartment 4, both the upper container 73 and the lower container 72 can be supplied. Fog.

When the nano platinum microparticle colloid is adhered to the mist release portion 49, the mist released from the mist release portion 49 is likely to generate hydroxyl radicals, and the sterilization function or the deodorizing function can be further enhanced. Further, by including the conductive material (carbon) in the mist release portion 49, the conductivity of the mist release portion 49 can be favorably maintained.

Since any one of the doors 3a, 4a, 5a, 6a, 7a which is made into the storage room (refrigerator 3, the fruit and vegetable compartment 4, the ice making compartment 5, the small freezer compartment, and the freezer compartment 7) is opened, Since the structure in which the electrostatic atomization device 36 is energized is blocked, it is possible to prevent the user from coming into contact with the high voltage portion, and it is possible to improve safety. At this time, at least the structure in which the energization of the electrostatic atomization device 36 is blocked when the door 3a of the refrigerator compartment 3 is opened is provided.

Further, in the present embodiment, the lid switch 62 that is configured to open and close the lid 40 that detects the unit housing portion 41 in which the electrostatic atomizing device 36 is housed is provided, and when the lid 40 is opened, the electrostatic atomization can be blocked. The powering up of the device 36 makes it possible to improve safety.

Further, since the unit detecting switch 61 is provided in the unit accommodating portion 41, the electrostatic atomizing device 36 is not energized when the atomizing unit 38 is not mounted, and the safety can be further improved.
