The front end portion of the upper container 73 is positioned below the mist outlet 52 of the base plate 37. Then, in this state, when the mist is released from the mist outlet 52 into the vegetable compartment 4, the mist is supplied to both the lower container 72 and the upper container 73.

  At the back of the refrigerator body 1, a control device 75 (see FIG. 1) including a microcomputer is provided. The control device 75 is a refrigerator main body 1 such as a compressor 19 for refrigeration cycle, a refrigeration fan 14, a refrigeration fan 17, an automatic ice making device 12, a pump motor 30 of a water supply mechanism 29, an electrostatic atomizing device 36, a light source 70 Control function, and constitutes control means. In particular, for the electrostatic atomizer 36, the controller 75 detects that the door switch of each storage chamber is closed and the lid switch 62 detects that the lid 40 is closed. Only when the detection switch 61 detects the set state of the atomization unit 38, the electrostatic atomization device 36 is allowed to be energized, but the door of any storage chamber is opened, the lid 40 is opened, Alternatively, when it is detected that the atomization unit 38 is not set, the energization to the electrostatic atomization device 36 is cut off. Further, the control device 75 performs lighting control of the light source 70 for a predetermined period of time every predetermined time.

The operation of the above configuration will be described.
When the electrostatic atomization device 36 is driven in a state in which the atomization unit 38 is set in the unit housing portion 41, the lid 40 of the unit housing portion 41 is closed, and the door of each storage chamber is closed. Fine mists are released from the mist release parts 49, and the mists are supplied from the mist release port 52 into the upper container 73 and the lower container 72 of the vegetable compartment 4. The mist contains a hydroxy radical having a strong oxidizing action, and the mist containing the hydroxy radical is supplied into the upper container 73 and the lower container 72 of the vegetable compartment 4 to enable their sterilization and deodorization. Become. Moreover, freshness maintenance etc. of vegetables etc. accommodated in the upper container 73 and the lower container 72 can be expected by the mist. In addition, the lighting control of the light source 70 for a predetermined time is performed for each predetermined time, whereby the photocatalyst 69 in the water storage tank 43 is activated, and the sterilizing action in the water storage tank 43 can be expected.

  By the way, since the electrostatic atomizer 36 can not generate mist when the water runs out, it is necessary to periodically replenish the water. In addition, if dirt such as slime adheres to the surface of the mist release part 49 and clogging occurs with use, the mist release performance decreases, so for example, the mist release part 49 is cleaned about once a year. It is preferable to do.

  In such a case, after the door 3a of the refrigerator compartment 3 is opened, the lid 40 of the front part 8a of the partition plate 8 is slid to open the opening 39 of the unit housing portion 41. Then, the user inserts a hand into the unit housing portion 41 and holds the atomizing unit 38 of the electrostatic atomizing device 36, slides it forward, then lifts it out of the unit housing portion 41. At this time, the connection of the power supply pin 54 to the connector 58 is disconnected. And in the case of only supplying water, water is supplied from the water injection port 67 with the water injection lid 68 removed. Moreover, when cleaning the mist discharge part 49, while removing the upper case 44 from the water storage tank 43, the discharge part cover 50 is removed from the upper case 44, and the cleaning is performed in the state which exposed the mist discharge part 49. In addition, in the case of only supplying water, it can also be performed by removing only the water injection lid 68 while the atomization unit 38 is set in the unit housing portion 41.

  After the water supply and cleaning are completed, the atomization unit 38 is assembled as it is, and then the atomization unit 38 is housed in the unit housing portion 41 and set at a regular position. At this time, the feed pin 54 is inserted and connected to the connector 58. Thereafter, the lid 40 is slid forward to close the opening 39, and the door 3a of the refrigerator compartment 3 is closed.

According to the first embodiment described above, the following effects can be obtained.
The electrostatic atomizer 36 is installed on the partition plate 8 between the refrigerator compartment 3 and the vegetable compartment 4 and the mist released from the mist release part 49 of the electrostatic atomizer 36 is mainly supplied to the vegetable compartment 4 It was set up. Thereby, sterilization and deodorization in the vegetable compartment 4 become possible by the mist containing the hydroxy radical which has strong oxidation action being supplied to the vegetable compartment 4. FIG. Moreover, freshness maintenance of vegetables etc. can also be expected by the mist.

  As the electrostatic atomizer 36, since the counter electrode to the mist discharge part 49 is not installed in the vicinity of the mist discharge part 49, the corona discharge is generated between the mist discharge part and the counter electrode in the conventional structure Unlike products, it can suppress the generation of harmful gases such as ozone, which is one of the problems, and can improve safety.

  The electrostatic atomization device 36 has a water storage tank 43 for storing water W, and the water W stored in the water storage tank 43 is discharged through the water absorbing pin 48, the water retention material 47, and the conductive sheet 46 to each mist discharge portion It is configured to supply 49. As a result, water can be stably supplied to the mist release unit 49, so the amount of mist generation from the mist release unit 49 can also be stabilized.

  In addition, since the water storage tank 43 is attachable to and detachable from the unit storage unit 41 together with the atomization unit 38, the water storage tank 43 can be easily replenished with water. Since the mist discharge part 49 is also attachable to and detachable from the water storage tank 43, the mist discharge part 49 can be cleaned easily.

  Since the filtration filter 65 is provided in the water storage tank 43, the water replenished in the water storage tank 43 can be purified, and clean water can be supplied to the mist discharge unit 49. As a result, the occurrence of clogging in the mist release portion 49 and the like can be prevented as much as possible, and a decrease in the amount of mist release can be prevented. Further, since the ion exchange resin 66 is provided in the filtration filter 65, the minerals contained in the water W stored in the water storage tank 43 can be removed by adsorbing it by the ion exchange resin 66. . As a result, the accumulation of the scale in the mist release portion 49 and the like can be prevented as much as possible, the occurrence of clogging can be further prevented, and the decrease in the amount of mist release can be further prevented. By these, it becomes possible to extend the service life of the mist discharge part 49.

  In addition, the lighting control of the light source 70 for a predetermined time is performed for each predetermined time, whereby the photocatalyst 69 in the water storage tank 43 is activated, and the sterilizing action in the water storage tank 43 can be expected. Also by this, clean water can be supplied to the mist discharge part 49. Therefore, while using an electrostatic atomizer as the mist generation means, it is possible to generate and supply mist containing hydroxy radical having a sterilizing action to the storage room, and a clean and safe refrigerator can be provided. .

  Since the atomization unit 38 of the electrostatic atomization device 36 is installed at the front 8 a of the partition plate 8, it is possible to easily supply water to the atomization unit 38 and attach or detach the atomization unit 38. Since the mist emitted from the mist discharge unit 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. It can supply mist.

  By supporting the platinum nanocolloid in the mist release unit 49, hydroxy radicals are more easily generated in the mist released from the mist release unit 49, and it becomes possible to further improve the sterilization function and the deodorizing function. Further, by including the conductive substance (carbon) in the mist release part 49, the conductivity of the mist release part 49 can be maintained well.

  When any of the doors 3a, 4a, 5a, 6a, 7a of the storage room (refrigeration room 3, vegetable room 4, ice making room 5, small freezing room, freezing room 7) is opened, the electrostatic atomizer 36 Since the configuration is such that energization is cut off, the user can be prevented from touching the high voltage part, and safety can be improved. In this case, at least when the door 3a of the refrigerator compartment 3 is opened, the electrification of the electrostatic atomizer 36 may be cut off. Further, in the present embodiment, the lid switch 62 for detecting the opening and closing of the lid 40 of the unit housing portion 41 housing the electrostatic atomizing device 36 is provided, and the electrostatic atomizing device is also provided when the lid 40 is opened. Since the energization of 36 is cut off, the safety can be further improved. Furthermore, the unit detection unit 61 is provided with the unit detection switch 61, and even when the atomization unit 38 is not set, the electrification of the electrostatic atomization device 36 is cut off, thereby further improving the safety. .

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

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

  At this time, the mist discharge port 203 is located almost directly below the mist discharge portion 49 and faces the cold air passage 201 from above, so the mist discharged from the mist discharge portion 49 is on the inner bottom surface of the base plate 37 or the like. The collision can be suppressed as much as possible, and the mist can be prevented from adhering to the inner bottom surface of the base plate 37 and the like as much as possible. Moreover, since the mist discharged from the mist discharge part 49 is drawn in the cold air flowing from the rear to the front from the rear, the mist tends to flow out to the cold air passage 201 side, and the mist is inside the base plate 37. There is an advantage that it is possible to further suppress the reduction due to collision with the bottom surface and the like, and it becomes possible to supply more mist into the vegetable compartment 4.

  According to the present specification, in a device using an ultrasonic atomization device as the mist generation device, the particle diameter of the mist is large, and the dirt component contained in the stored water of the mist generation device is also blown as the mist It may be supplied to the storage room. On the other hand, in the case of using an electrostatic atomizer, the particle size of the mist can be reduced (for example, several nm to several tens nm level). The object is to provide a clean and safe refrigerator which can generate mist and supply it to a storage room using an atomizing device as mist generation means.
