The control device 46 functions to control the compressor 19, the refrigeration fan 14, the refrigeration fan 17, the automatic ice making device 10, the electrostatic atomizer 22, the display unit, and the like based on these signals and a control program prepared in advance. And constitutes a control means.

The operation of the above configuration will be described.
In the electrostatic atomizer 22, the water W stored in the water storage tank 29 is sucked up by the water absorption pins 34 and supplied to the water retaining material 35. The water supplied to the water retaining material 35 is supplied to each mist discharge pin 37 via the conductive member 36. Further, each mist discharge pin 37 is electrically connected to the negative electrode of the high-voltage transformer 24 through the conductive member 36, the electrical connection pin 39, and the main body side electrode portion 27. When a negative high voltage (for example, −several kV) is applied to each mist discharge pin 37 from the high-voltage transformer 24, the moisture on the surface of each mist discharge pin 37 is split and released as a fine mist. Become so. In this case, in the electrostatic atomizer 22, the counter electrode for the mist discharge pin 37 is not installed in the vicinity of the mist discharge pin 37.

  The mist discharged from each mist discharge pin 37 exits the cover 31 from each opening 42 of the cover 31 and is supplied into the upper container 12 and the lower container 11 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 12 and the lower container 11 of the vegetable compartment 4 so that they can be sterilized and deodorized. Become. Moreover, the freshness maintenance of the vegetables etc. which were accommodated in the upper container 12 and the lower container 11 by the mist can be expected. In this case, since a plurality of mist discharge pins 37 are arranged in parallel along the lower surface of the mounting plate 21 that is an installation surface and are radially arranged, it is possible to supply mist over a wide range.

  By the way, since the electrostatic atomizer 22 cannot generate mist when water runs out, it is necessary to replenish water periodically. In addition, when the surface of the mist discharge pin 37 is clogged with the use of the mist discharge pin 37 due to use, the mist discharge performance deteriorates. For example, the mist discharge pin is cleaned about once a year. It is preferable.

  Therefore, for example, when only replenishing water, the user opens the door 4 a of the vegetable compartment 4. Then, the control apparatus 46 stops the electric power feeding with respect to the electrostatic atomizer 22 based on the signal of a door switch. And a user inserts a hand in the vegetable compartment 4, and cancels | releases the engagement with respect to the engagement hole 44 of each engaging claw 43 in the water storage tank 29, holding the water storage tank 29 of the atomization unit 23 by hand. Thus, the water storage tank 29 is removed from the cover 31 and taken out of the vegetable compartment 4. Then, after water is supplied to the water storage tank 29, the water storage tank 29 is inserted into the vegetable compartment 4 while being held by hand, and each engagement claw 43 of the water storage tank 29 is engaged with the engagement hole 44 of the cover 31. Then, the water storage tank 29 is attached to the lower surface of the cover 31.

  When cleaning the mist discharge pin 37 and the like, the user inserts his hand into the vegetable compartment 4 with the door 4a of the vegetable compartment 4 open, and holds the atomization unit 23 by hand. However, the atomization unit 23 is removed from the mounting plate 21 by releasing the engagement of the respective engagement claws 40 of the cover 31 with the engagement holes 41. At this time, the electrical connection pin 39 is pulled out from the main body side electrode portion 27. And after taking out the atomization unit 23 out of the vegetable compartment 4, the required part of the atomization unit 23 is removed, and the mist discharge | release pin 37 etc. are cleaned. When the cleaning or the like is completed, the atomizing unit 23 is attached to the attachment plate 21 in the reverse procedure to that described above.

  According to the above-described embodiment, the following effects can be obtained. The mist discharge pins 37 of the atomization unit 23 are oriented so as to be parallel to the lower surface of the mounting plate 21 that is the installation surface of the atomization unit 23, and a plurality of mist discharge pins 37 are arranged radially. The mist released from 37 can be applied over a wide range. There is also an advantage that the height dimension of the atomization unit 23 can be suppressed.

  The atomizing unit 23 includes a cover 31 that covers the mist discharge pin 37, and the cover 31 has a plurality of openings 42 in the peripheral wall 31 b that faces the tip of the mist discharge pin 37. According to this configuration, while the cover 31 prevents the finger or the like from inadvertently touching the mist discharge pin 37, the air permeability around the mist discharge pin 37 can be secured, and the mist diffusibility can be increased. Can be good.

  Since the water storage tank 29 is detachably attached to the lower surface of the cover 31, the water storage tank 29 can be easily attached and detached. Further, since the water storage tank 29 is located below the opening 42 of the cover 31, it is possible to prevent the air flow through the opening 42 from being obstructed.

Since the main body side electrode portion 27 is provided downward, it is possible to prevent the main body side electrode portion 27 from being inadvertently splashed with water.
Since the electrostatic atomizer 22 does not have a counter electrode in the vicinity of the mist discharge pin 37 and is not configured to discharge, it does not generate ozone, which is harmful to the human body, unlike the discharge, and is safe. There is an advantage of superiority.
