The injection valve 78 uses an injection valve solenoid as a drive source, and is in a closed state in which water cannot pass through when the injection valve solenoid is electrically turned off. The injection valve 78 is in an open state in which water can pass when the injection valve solenoid is electrically turned on. When the injection valve 78 is in an open state, the active water in the water receiving container 55 of the active water generating mechanism 32 is discharged. The water is injected from the drain pipe 66 into the tank 71 through the water receiving port 76 and the injection pipe 75.

  As shown in FIG. 2, an ultrasonic vibration element 79 is fixed to the tank 71 on the bottom plate of the case 72. The ultrasonic vibration element 79 is disposed outside the tank 71 and vibrates at a specific frequency of 20 k to 10 MHz when power is supplied from the power supply circuit. When the ultrasonic vibration element 79 vibrates, the vibration is transmitted to the active water in the tank 71 through the wall surface of the tank 71, and when the vibration is transmitted to the active water in the tank 71, the active water is atomized. As a result, it becomes a mist for sterilization. That is, the mist generating mechanism 33 is composed of an ultrasonic atomizer.

The mist port 80 discharges the mist in the tank 71 into the R cool air passage 11. When the mist is discharged from the mist port 80 into the R cool air passage 11 in the operating state of the R fan device 15, the R It is carried on the wind rising in the cold air passage 11. This mist is supplied into the refrigerator compartment 4 from each of the final outlet 13 and the intermediate outlet 14 of the R cold air passage 11, and when the mist is supplied into the refrigerator compartment 4, the inside of the refrigerator compartment 4 and the vegetable compartment Each of 5 is gradually sterilized and deodorized by the oxidizing power of reactive oxygen species of mist.

According to the said Example 1, there exists the following effect.
By applying a voltage between the working electrode 59 and the GND electrode 63, a discharge on the water surface is generated between the water surface of the defrost water in the water receiving container 55 and the horizontal plate 60 of the working electrode 59. Active water containing active oxygen species is generated by generating a discharge between the water surface of the defrosted water and the horizontal plate 60 of the working electrode 59. When active water is generated, the active water is atomized. Mist for sterilization was generated. For this reason, since the mist rides on the wind in the R cold air passage 11 and is supplied into the refrigerating chamber 4, the inside of the refrigerating chamber 4 is gradually sterilized and deodorized by the oxidizing power of the active oxygen species of the mist. Applications are expanded.

  Since the surface of the working electrode 59 is covered with an inorganic insulating material, the discharge is repeated between the water surface of the defrosted water in the water receiving container 55 and the horizontal plate 60 of the working electrode 59, thereby the horizontal plate of the working electrode 59. 60 is prevented from being destroyed.

  The microbubble generator 64 is housed in the water receiving container 55, and a voltage is applied between the working electrode 59 and the GND electrode 63 to generate a discharge inside the microbubbles in the defrosted water in the water receiving container 55. It was. For this reason, since active water is produced | generated also by discharge generate | occur | producing inside a microbubble, the production | generation of active water is made efficient. Moreover, the microbubble generator 64 is arranged below the GND electrode 63 in the vertical direction. For this reason, since microbubbles adhere to the surface of the GND electrode 63, the generation of active water is made more efficient.

  Since the air layer 77 is provided between the joint 67 of the active water generating mechanism 32 and the water receiving port 76 of the mist generating mechanism 33, the mist generating mechanism 33 is electrically insulated from the active water generating mechanism 32. Therefore, the electronic components around the mist generating mechanism 33 are not electrically connected to the active water generating mechanism 32 via the mist generating mechanism 33, so that malfunction occurs in the electronic components around the mist generating mechanism 33.

  As shown in FIG. 5, a water supply mechanism 31, an active water generation mechanism 32, and a mist generation mechanism 33 are fixed in the outer box 101. Each of the water supply mechanism 31, the active water generation mechanism 32, and the mist generation mechanism 33 is disposed outside the circulation passage, and the inlet of the water supply valve 42 of the water supply mechanism 31 is connected to a water tap through a hose 43. Has been. A case is fixed in the box 41 of the water supply mechanism 31, and the case is filled with an ion exchange resin. This case is interposed in the pipe 44. When the water supply valve 42 is open, tap water is injected into the water receiving container 55 of the active water generating mechanism 32 through the ion exchange resin in the case. This tap water contains scale components such as calcium ions, and the scale components are removed by exhibiting an ion exchange action with an ion exchange resin in the case, and the tap water from which the scale components are removed is provided in the active water generation mechanism 32. Water is supplied.

  As shown in FIG. 5, a curved mist port 81 is fixed to the cover 73 of the mist generating mechanism 33 in place of the straight mist port 80. The upper end portion of the mist port 81 is inserted into the rear duct 120 of the circulation passage. In the dehydration process, the ultrasonic vibration element 79 of the mist generating mechanism 33 is operated, so that the mist is transferred from the mist port 81 into the rear duct 120. Is released. The mist rides on warm air for drying the clothes and is supplied from the water receiving tank 104 to the clothes in the drum 111 to sterilize and deodorize the clothes in the drum 111.

According to the said Example 2, there exist the following effects.
Tap water was supplied into the water receiving container 55 of the active water generation mechanism 32 through the ion exchange resin in the water supply mechanism 31. Therefore, the tap water from which the scale component has been removed is stored in the water receiving container 55 of the active water generation mechanism 32, and the active water from which the scale component has been removed is supplied from the active water generation mechanism 32 to the mist generation mechanism 33. Mist from which the scale component has been removed is released from the generation mechanism 33 into the rear duct 120. And since the electrical conductivity of tap water falls by removing a scale component from the tap water in the water supply mechanism 31, the tap water with low electrical conductivity is stored in the water receiving container 55. FIG. For this reason, since it becomes easy to generate | occur | produce discharge between the water surface of the tap water in the water receiving container 55 and the horizontal plate 60 of the working electrode 59, it becomes easy to generate discharge inside the microbubble in the water receiving container 55. Despite using tap water, active water is stably generated.

  In the first embodiment, the inlet of the water supply valve 42 of the water supply mechanism 31 may be connected to a tap faucet, and tap water may be supplied from the water supply mechanism 31 into the water receiving container 55 of the active water generating mechanism 32. In this case, it is preferable to remove the scale component from the tap water by filling the water supply mechanism 31 with an ion exchange resin.

In each of the first and second embodiments, the surfaces of the working electrode 59 and the GND electrode 63 may be covered with glass.
In each of the first and second embodiments, an electrostatic atomizer may be used as the mist generating mechanism 33.
