In addition to expecting the effects of sterilization and deodorization at the supply destination, it can also be expected to maintain moisture and freshness of vegetables.

According to the first embodiment described above, the following operational effects can be obtained.
An electrostatic atomization device 48 that constitutes a sterilization component generating means is installed in the back of the chilled chamber 14, and a mist containing a sterilization component (hydroxy radical) generated in the electrostatic atomization device 48 is removed from the chilled chamber 14. Therefore, it is possible to easily sterilize and deodorize the chilled chamber 14 where meat, fish, and the like are stored, and also to maintain moisture and maintain freshness.

Since the mist containing the sterilizing component generated in the electrostatic atomizer 48 is also supplied to the vegetable chamber 4 adjacent to the chilled chamber 14, the vegetable chamber 4 can be sterilized and deodorized. Moisturizing vegetables and keeping freshness is also possible.
The chilled chamber 14 is provided with a chilled case 18 and is provided with a chilled chamber mist outlet 65 for supplying mist containing a sterilizing component generated in the electrostatic atomizer 48 into the chilled case 18.

As described above, the mist containing the sterilizing component (hydroxy radical) can be supplied to the chilled chamber 14, so that the chilled chamber 14 can be sterilized and deodorized, and the moisture and freshness can be maintained. Is also possible. Moreover, since the water used in the electrostatic atomizer 48 uses the defrost water of the refrigeration cooler 24 stored in the water storage container 56, the water supply to the water storage container 56 can be automatically performed. It is possible to save the user (user) from having to supply water.
Since the refrigeration cooler 24 is installed behind the chilled chamber 14, it is possible to use defrosted water from the refrigeration cooler 24 near the chilled chamber 14 as water used in the electrostatic atomizer 48. it can.

  The refrigerator-freezer of this embodiment employs a two-evaporation refrigeration cycle that includes two coolers, a refrigeration cooler 24 and a refrigeration cooler 25. Here, the ambient temperature of the refrigeration refrigerator 25 of the refrigerator / freezer that employs the two-evaporation refrigeration cycle as in this embodiment and the ambient temperature of the refrigerator of the one-evaporator refrigerator / freezer are excluded during defrosting. Although it becomes a positive temperature by heating with a frost heater, it is always at a temperature of -20 ° C or lower except during defrosting. If the water storage container is installed below these coolers, even if the defrost water is received and stored in the water storage container during defrosting of the cooler, the water in the water storage container is easily frozen and hardly melts. . For this reason, there is a problem that water cannot be stably supplied to the mist discharging unit 50.

  In this regard, in the present embodiment, in a two-evaporation type refrigerator-freezer provided with two coolers, a refrigeration cooler 24 and a refrigeration cooler 25, a water storage container 56 is installed below the refrigeration cooler 24.

For this reason, the water in the water storage container 56 installed below the refrigeration cooler 24 is difficult to freeze, and even if it freezes, it is easy to melt, so that the water supply to the mist discharge unit 50 can be stably performed. Can be done.

  The mist discharge part 50 of the electrostatic atomizer 48 is configured by a plurality of mist discharge pins (protrusions) 57 protruding in different directions. With this configuration, unlike the case where the protruding direction of the projection for generating mist is only one direction, the supply direction of mist can be a plurality of directions, and the supply range of mist can be widened.

The mist discharge part 50 is configured such that the mist discharge pin (projection) 57 extends in the opposite direction up and down with the horizontal part 53a of the water supply part 53 in between, so that the mist can be discharged in the opposite direction above and below. The mist supply range can be widened. Further, the horizontal portion 53a of the water supply portion 53 and each mist discharge pin 57 are arranged along the front wall 36a so as to be parallel to the front wall 36a of the refrigeration cooler chamber 36 in the cold air duct 34. It is possible to reduce the thickness in the front-back direction. By arranging the mist discharge pins (protrusions) 57 in two upper and lower stages, it is possible to reduce the size.

The power supply device 52 is disposed on the opposite side of the refracting portion 53c with the mist emitting portion 50 in between. Thereby, the power supply device 52 can be further separated from the water storage container 56.
In addition, by arranging the power supply device 52 and the mist generating unit 51 along the front wall 36a so as to be parallel to the front wall 36a of the refrigeration cooler chamber 36 in the cold air duct 34, electrostatic atomization is achieved. The device 48 can be thinned in the depth direction.

  A mist discharge pin (projection) 57 in the mist discharge portion 50 of the electrostatic atomizer 48 is arranged along the cold air duct 34. Thereby, it becomes possible to suppress the depth dimension of the electrostatic atomizer 48 in the front-rear direction, and the thickness can be reduced. Accordingly, it is possible to suppress a decrease in the internal volume.

  A mist cold air supply port 62 for supplying cold air into the mist dedicated duct 45 is provided at the front of the cold air duct 34, and the mist discharge portion 50 of the electrostatic atomizer 48 is connected to the front of the cold air duct 34. Arranged. Accordingly, it is possible to fly the mist discharged from the mist discharge unit 50 far using the cooling air supplied from the mist cold air supply port 62 into the mist dedicated duct 45.

  Since the mist cold air supply port 62 and the mist discharge portion 50 (mist discharge pin 57) are arranged at positions shifted left and right so as to be different from the opposed positions, the mist cold air supply port 62 and the mist dedicated duct are disposed. The cooling air supplied into 45 does not directly hit the mist discharge part 50 (mist discharge pin 57). This makes it possible to prevent the mist discharge pin 57 from directly receiving the cooling air from the mist cold air supply port 62 and drying.

More specifically, the plurality of mist outlets are a mist outlet 63a for a refrigerator compartment, a mist outlet 65 for a chilled room, a mist outlet 66 for an egg case, and a mist outlet 67 for a vegetable compartment. Thus, the mist generated in the mist dedicated duct 45 can be supplied to the four supply destinations of the refrigerator compartment 3, the chilled compartment 14, the egg case 15, and the vegetable compartment 4, thereby widening the supply range of the mist. And the mist effect range can be expanded. Among the mist supply destinations, the chilled chamber 14, the egg case 15, and the vegetable chamber 4 have a chilled case 18, an egg case 15, and a vegetable case (lower case 11, upper case 12), respectively. It can be supplied satisfactorily.

  In this case, the plurality of mist outlets (the mist outlet 63a for the refrigerator compartment, the mist outlet 65 for the chilled room, the mist outlet 66 for the egg case, and the mist outlet 67 for the vegetable compartment) are the mist discharge part 50. Therefore, the mist discharged from the mist discharge section 50 can be satisfactorily supplied to each mist outlet.

The mist generating unit 51 has a mist discharge pin (projection) 57, and the plurality of mist outlets (the mist outlet 63a for the refrigerator compartment, the mist outlet 65 for the chilled chamber, the egg), and the egg Since the mist outlet 66 for the case and the mist outlet 67 for the vegetable compartment are arranged at positions different from the positions facing the mist discharge pins 57, the mist outlet ducts should be used by any chance. Even if a finger or a foreign object is inserted into 45, it can be prevented that they touch the mist discharge pin 57 directly, and safety can be ensured.
Further, since the duct component member 46 forming the mist dedicated duct 45 is detachable, maintenance of the mist generating unit 51 and the like can be easily performed.
