It is a space that extends upward along the back surface of the chilled chamber 12.

An atomizing device 40, which is located below the mist generating duct 37 and releases the hydrogen peroxide solution on the wind generated by the operation of the refrigeration blower fan 28, is arranged in the lower part of the refrigerating cooler chamber 29. It is set up. The atomizing device 40 will be described below.

The atomizing device 40 includes a water storage container 41 that constitutes a water storage portion, a pair of electrodes 42 and 43 provided inside the water storage container 41, and a suction means 44 that sucks up the water in the water storage container 41. The water storage container 41 is in the shape of a rectangular container having an opening on the upper surface, and is provided in the refrigerating cooler chamber 29 between the refrigerating cooler 17 and the drain gutter 33. In this example, a part of the water storage container 41 is arranged so as to project forward from the refrigerating cooler 17, and the front part of the water storage container 41 vertically faces the mist generating duct 37. Further, the rear part of the water storage container 41 is vertically opposed to the refrigerating cooler 17, and receives defrosting water dripping from the refrigerating cooler 17 when the refrigerating cooler 17 is defrosted. Store in.

The pair of electrodes 42, 43 are provided inside the water storage container 41 in parallel with each other at a predetermined interval so as to be immersed in the water stored in the predetermined water storage container 41. The pair of electrodes 42, 43 functions as a generating unit that is connected to a power supply device (not shown) and electrolyzes water in the water storage container 41 to generate hydrogen peroxide by applying a predetermined voltage.

The wicking means 44 is made of a sheet material having water absorbency and air permeability such as woven fabric and non-woven fabric, and is provided with a plurality of through holes 44a as shown in FIG. The suction means 44 is provided in the mist generating duct 37 so that the upper part partitions the mist generating duct 37 into front and rear, and the lower end part is immersed in the water stored in the water storage container 41. In this example, the lower end of the suction means 44 is provided between the pair of electrodes 42 and 43 and is sandwiched between the pair of electrodes 42 and 43, as shown in FIG. The suction means 44 as described above sucks the hydrogen peroxide solution generated in the water storage container 41 upward by a capillary phenomenon and holds the sucked hydrogen peroxide solution in the mist generating duct 37.

The suction means 44 is preferably made of a hydrophilic material such as rayon, nylon, polyester, cotton, or pulp in order to easily suck up the hydrogen peroxide solution in the water storage container 41.

Further, in this example, the case where the suction means 44 is provided with a plurality of through holes 44a will be described. However, for example, a plurality of uneven shapes or pleats may be provided on the surface of the suction means 44 to form the suction means 44. It may be processed to increase the surface area. By increasing the surface area of the suction means 44 in this manner, the hydrogen peroxide solution sucked up by the suction means 44 is likely to become a mist.

The back surface of the mist generating duct 37 is provided with an air introduction port 49 opening to the refrigerating cooler chamber 29 below the refrigerating cooler 17, and the mist generating duct 37 is connected to the refrigerating cooler via the air introducing port 49. It communicates with the chamber 29. As a result, a part of the air (cool air) flowing through the refrigerating cooler chamber 29 during the operation of the refrigerating blower fan 28 before the heat exchange with the refrigerating cooler 17 produces mist from the air introduction port 49. It is introduced into the duct 37.

The air introduced into the mist generating duct 37 from the air introduction port 49 is blown to the suction means 44 from the rear side, and when the air flows through the suction means 44 to the front side, the hydrogen peroxide solution held by the suction means 44 is vaporized. It turns into mist. The mist generated in the mist generation duct 37 rides on the flow of air introduced into the mist generation duct 37, and enters the chilled chamber 12 from the chilled chamber outlet 50 provided in the upper front part of the mist generation duct 37. It is being supplied.

Further, a mist duct 51 is connected to the upper portion of the mist generation duct 37. The mist duct 51 is opened above the refrigerating cooler 17 (that is, on the downstream side of the refrigerating cooler 17 in the cold air flow direction), and connects the mist generating duct 37 and the cold air supply duct 30. .. As a result, the mist generated in the mist generation duct 37 rides on the flow of the air introduced into the mist generation duct 37, passes through the mist duct 51 and the cold air supply duct 30, and flows from the cold air supply port 32 to the inside of the refrigerating chamber 3. Is also being supplied to.

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

The refrigeration blower fan 28 blows air toward the suction means 44 which sucks up the hydrogen peroxide solution generated in the water storage container 41 and holds it, thereby removing mist from the hydrogen peroxide solution held by the suction means 44. Since it is generated, it is difficult to add mechanical energy such as vibration and heat or heat energy, and mist can be generated while suppressing decomposition of hydrogen peroxide solution. Therefore, the hydrogen peroxide solution can be supplied to the storage rooms such as the refrigerating room 3 and the chilled room 12 without producing a high-concentration hydrogen peroxide solution. It is possible to obtain excellent sterilization and deodorizing effects by hydrogen peroxide water.

Further, in the present embodiment, the mist generating duct 37 provided with the suction means 44 is branched from the refrigerating cooler chamber 29 and is provided in parallel with the flow path in which the refrigerating cooler 17 is arranged. Since the air containing the mist of the hydrogen peroxide solution does not exchange heat with the refrigerating cooler 17 by being introduced into the generation duct 37 and passing through the suction means 44, the hydrogen peroxide solution contained in the air is refrigerated. It can be supplied to a storage room such as the chilled room 12 or the refrigerating room 3 without frosting on the cooling unit 17 for the refrigerator.

Further, in the present embodiment, since the suction means 44 is immersed in the water of the water storage container 41 while being sandwiched between the pair of electrodes 42, 43, the suction means 44 is located near the electrodes 42, 43 where hydrogen peroxide solution is generated. The suction means 44 can be provided, and the generated hydrogen peroxide water can be efficiently sucked up and supplied as mist to the storage chamber, and the lower end portion of the suction means 44 is provided with a pair of electrodes 42, 43. Can be held at.

In the above-described embodiment, the case where the suction means 44 is sandwiched between the pair of electrodes 42, 43 has been described, but the suction means 44 is provided between the pair of electrodes 42, 43 with a gap between each of the electrodes 42, 43. Alternatively, the lower end of the suction means 44 may be provided at a position apart from the pair of electrodes 42, 43.

Further, in the above-described embodiment, the case where the refrigeration blower fan 28 that circulates the cool air generated by the refrigerating cooler 17 also serves as the blower unit that blows air to the suction unit 44 has been described. A fan that blows air to the suction means 44 may be provided separately from the blower fan 28.

Here, the return air duct 89, the connection hose 88, the ventilation duct 86, the casing 92 of the blower 91 for circulation, the connection hose 93, and the air supply duct 94 constitute a circulation air passage 95 that is connected to the water tank 66. ..

The circulation blower 91 has a centrifugal impeller 96 inside a casing 92, and has a fan motor 97 for rotating the centrifugal impeller 96 outside the casing 92. The circulation blower 91 functions as a blowing unit that circulates the air in the water tank 66 (in the drum 60) through the circulation air passage 95. Inside the ventilation duct 86 of the circulation air passage 95, an evaporator 98 is arranged at the front part and a condenser 99 is arranged at the rear part.
