The object of the present invention is to provide a clean and safe refrigerator capable of generating mist containing radicals and supplying it to a storage room.

  In order to achieve the above-described object, the present invention provides a mist discharge section that discharges mist, a water supply section that supplies moisture to the mist discharge section, and the mist discharge section in a refrigerator having a storage room in a refrigerated temperature zone. A mist discharged from the mist discharge portion, and an electrostatic atomizer having a power supply device that applies a negative voltage to the mist discharge portion, and a counter electrode with respect to the mist discharge portion is not installed in the vicinity of the mist discharge portion. Is configured to be supplied to the storage chamber.

In addition, by controlling lighting of the light source 70 for a predetermined time every predetermined time, the photocatalyst 69 in the water storage tank 43 is activated, and a sterilization action in the water storage tank 43 can be expected.

  By the way, since the electrostatic atomizer 36 cannot generate mist when water runs out, it is necessary to replenish water regularly. Further, when dirt such as slime adheres to the surface of the mist discharge portion 49 with use and clogging occurs, the mist discharge performance deteriorates. For example, the mist discharge portion 49 is cleaned about once a year. It is preferable to do.

  In such a case, after opening the door 3a of the refrigerator compartment 3, the lid 40 of the front portion 8a of the partition plate 8 is slid to open the opening 39 of the unit accommodating portion 41.

It was set as the structure to do. Thereby, the mist containing the hydroxy radical which has a strong oxidizing action is supplied to the vegetable compartment 4, so that sterilization and deodorization in the vegetable compartment 4 can be performed. The mist can also be expected to maintain the freshness of vegetables and the like.

  The electrostatic atomizer 36 has a conventional configuration in which a corona discharge is generated between the mist emitting portion and the counter electrode because the counter electrode for the mist emitting portion 49 is not installed in the vicinity of the mist emitting portion 49.

As a result, the occurrence of clogging in the mist discharge portion 49 and the like can be prevented as much as possible, and a decrease in the amount of mist discharged can be prevented. In addition, since the ion exchange resin 66 is provided in the filtration filter 65, minerals contained in the water W stored in the water storage tank 43 can be removed by adsorbing the ion exchange resin 66. . As a result, it is possible to prevent the scale from accumulating in the mist discharge portion 49 as much as possible, to further prevent clogging, and to further prevent a decrease in the amount of mist discharged. As a result, the service life of the mist discharge part 49 can be extended.

  In addition, by controlling lighting of the light source 70 for a predetermined time every predetermined time, the photocatalyst 69 in the water storage tank 43 is activated, and a sterilization action in the water storage tank 43 can be expected. Also by this, clean water can be supplied to the mist discharge part 49.

  Since the atomization unit 38 of the electrostatic atomizer 36 is installed in the front portion 8a of the partition plate 8, water can be replenished to the atomization unit 38 and the atomization unit 38 can be easily attached and detached. Since the mist discharged from the mist discharge portion 49 of the atomization unit 38 is supplied from above to both the upper container 73 and the lower container 72 in the vegetable compartment 4, both the upper container 73 and the lower container 72 are provided. Mist can be supplied.

  By supporting the platinum nanocolloid on the mist releasing part 49, hydroxy radicals are more easily generated in the mist released from the mist releasing part 49, and the sterilization function and the deodorizing function can be further improved. In addition, since the conductive material (carbon) is included in the mist emitting portion 49, the conductivity of the mist emitting portion 49 can be maintained well.

  When one of the doors 3a, 4a, 5a, 6a, 7a of the storage room (refrigeration room 3, vegetable room 4, ice making room 5, small freezer room, freezer room 7) is opened, the electrostatic atomizer 36 Since it is set as the structure by which electricity supply is interrupted | blocked, it can prevent that a user touches a high voltage part and can aim at the improvement of safety | security. In this case, at least when the door 3a of the refrigerator compartment 3 is opened, the energization of the electrostatic atomizer 36 may be cut off. Moreover, in this embodiment, the lid | cover switch 62 which detects opening / closing of the lid | cover 40 of the unit accommodating part 41 which accommodated the electrostatic atomizer 36 is provided, and when the lid | cover 40 is open | released, an electrostatic atomizer Since the energization of 36 is cut off, the safety can be further improved. Furthermore, since the unit detection switch 61 is provided in the unit accommodating portion 41 so that the energization of the electrostatic atomizer 36 is cut off even when the atomizing unit 38 is not set, the safety can be further improved. .

Next, a ninth embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, description is abbreviate | omitted, and a different part is demonstrated.
In the vegetable compartment 4, a cover 200 is provided below the partition plate 8 (below the base plate 37 for installing the electrostatic atomizer 36) along the lower surface of the partition plate 8. A space between the cover 20 and the partition plate 8 and the base plate 37 is a cold air passage 201. As shown by arrow D in FIG. 22, this cold air passage 201 sends the cold air blown forward from the rear part of the vegetable compartment 4 to a plastic bottle 202 or the like stored in the front part of the vegetable compartment 4. It is for cooling.

  The base plate 37 is provided with a mist discharge port 203 positioned below the atomization unit 38. The mist discharge port 203 is provided at a position below the mist discharge portion 49 (see FIG. 6) in the atomization unit 38, in this case, almost directly below and facing the cold air passage 201 from above.

  In the above configuration, when mist is discharged from the mist discharge portion 49 in the atomization unit 38, the mist is discharged from the mist discharge port 203 of the base plate 37 to the cold air passage 201, and the cold air passage 201 is directed from the rear to the front. It flows toward the front of the vegetable compartment 4 along the cold air flowing (see arrow D) and is supplied into the vegetable compartment 4.

  At this time, since the mist discharge port 203 exists almost directly below the mist discharge portion 49 and faces the cold air passage 201 from above, the mist discharged from the mist discharge portion 49 is formed on the inner bottom surface of the base plate 37 and the like. Collisions can be suppressed as much as possible, and mist can be prevented from adhering to the inner bottom surface of the base plate 37 and decreasing. In addition, since the mist discharged from the mist discharge portion 49 is drawn into the cold air flowing from the rear to the front through the cold air passage 201, the mist easily flows out to the cold air passage 201 side. There is an advantage that it is possible to further suppress the reduction by colliding with the bottom surface and the like, and to supply more mist into the vegetable compartment 4.
