The heat insulating material 59 is made of a synthetic resin having a higher heat insulating performance than the material of the case 51, and a spatial cold storage chamber 60 is formed in the heat insulating material 59. A cool storage agent container 61 made of a synthetic resin is stored in the cool storage agent storage chamber 60. The cool storage agent container 61 is a solid and corresponds to a package. The rear surface of the cool storage agent container 61 is in surface contact with the cooling plate 56, and the area of the rear surface of the cool storage agent container 61 is set smaller than the area of the heat absorbing surface 54 of the Peltier element 53.

  The cool storage agent container 61 is filled with a cool storage agent corresponding to a medium. This regenerator is composed of about 99% water containing a highly water-absorbent resin (sodium polyacrylate), a preservative, and a shape stabilizer. The regenerator has a melting point of 0 ° C to -3 ° C. The temperature range is set. This regenerator is in contact with the heat absorbing surface 54 of the Peltier element 53 via the regenerator container 61 and the cooling plate 56, and when the Peltier element 53 is electrically turned on, the Peltier element 53 is electrically turned on. Heat is released from the heat absorbing surface 54 of the element 53 through the heat radiating surface 55, the fin base 57, and the heat radiating fin 58 in this order to be cooled into the R cool air passage 11 to become a solid phase.

The air supply port 64 has a cylindrical shape directed in the left-right direction, and the right surface of the air supply port 64 is connected in the ventilation path 62 at a lower position than the dew condensation surface 63 of the cool storage agent container 61. An exhaust port 65 is formed in the top plate of the case 51. This exhaust port 65 is connected to the upper surface of the ventilation path 62 which consists of a through-hole. The exhaust port 65 and the air supply port 64 are for flowing air into the ventilation passage 62, and the air flowing from the bottom to the top in the R cool air passage 11 during the R cooling operation and the defrosting operation. Air enters the ventilation path 62 from the air supply port 64, and the air that has entered the ventilation path 62 flows from below to above along the ventilation path 62. The air flowing from the bottom to the top along the ventilation path 62 comes into contact with the dew condensation surface 63 of the cool storage agent container 61 and is returned from the exhaust port 65 into the R cool air passage 11.

  The Peltier element 53 is switched from an electrical OFF state to an ON state when the defrosting operation is started. When the Peltier element 53 is in the ON state, the heat absorption surface 54 of the Peltier element 53 is stored in the cool storage agent container 61. By absorbing heat from the agent, the cool storage agent in the cool storage agent container 60 is cooled to become a solid phase. When the defrosting operation is performed with the Peltier element 53 in the on state, the air in the refrigerator compartment 4 and the vegetable compartment 5 comes into contact with the dew condensation surface 63 of the regenerator container 61. This air has a higher temperature than the air during the R cooling operation and contains moisture from foods such as vegetables in the refrigerator compartment 4 and the vegetable compartment 5 and contacts the dew condensation surface 63 of the regenerator container 61. As a result, moisture is condensed and condensation occurs on the condensation surface 63.

  The Peltier element 53 is switched from the on state to the off state when a predetermined time elapses with reference to the fact that the Peltier element 53 is switched from the off state to the on state. The cool storage agent in the cool storage agent container 61 is stored in the refrigerator compartment 4 and in the vegetable compartment 5 within the cool storage period from when the cool storage agent in the cool storage agent container 61 is switched to before the phase transition from the solid phase to the liquid phase. It is in a cooled state so that the air can be condensed. When the defrosting operation is performed within the cool storage period of the cool storage agent, the air in the refrigerator compartment 4 and the vegetable compartment 5 is condensed by contacting the condensation surface 63 of the cool storage agent container 61.

  As shown in FIG. 3, a drain port 66 is fixed to the bottom plate of the case 51. The drain port 66 has a cylindrical shape oriented in the vertical direction, and the upper surface of the drain port 66 is connected to the lower surface of the ventilation path 62. The lower surface of the drainage port 66 is connected to the water injection port 32 of the mist generating unit 30, and water condensed on the condensation surface 63 of the cool storage agent container 61 falls into the ventilation port 62 and falls into the drainage port 66. . The water that has entered the drain port 66 falls along the drain port 66 to be injected into the tank 31 from the water injection port 32 of the mist generating unit 30 and is stored in the tank 31 as water for electrolysis.

According to the said Example 1, there exists the following effect.
In the ON state of the Peltier element 53, the cool storage agent in the cool storage agent container 61 is released by releasing heat from the cool storage agent in the cool storage agent container 61 into the R cool air passage 11 through each of the heat absorption surface 54 and the heat dissipation surface 55 of the Peltier element 53. Therefore, when the air passing through the ventilation path 62 of the case 51 contacts the dew condensation surface 63 of the regenerator container 61, the moisture in the air condenses on the dew condensation surface 63. In addition, since the cool storage agent in the cool storage agent container 61 is maintained in the solid phase during the cool storage period after the Peltier element 51 is switched from the on state to the off state and before the phase transition, the ventilation path of the case 51 When the air passing through 62 contacts the dew condensation surface 63 of the regenerator container 61, moisture in the air condenses on the dew condensation surface 63. For this reason, a large amount of water is generated on the dew condensation surface 63 of the regenerator container 61 with the Peltier element 53 turned on in a short time, and a large amount of water is injected from the dew condensation surface 63 into the tank 31 of the mist generation unit 30. Therefore, a large amount of mist can be discharged into the refrigerator compartment 4 with low power consumption.

  Since the heat insulating material 59 is provided in the case 51, it is possible to prevent heat from being transmitted from the outside of the case 51 through the cool storage agent container 61 to the cool storage agent in the cool storage agent container 61. For this reason, since the cold storage period from when the Peltier element 51 is switched from the on state to the off state until before the phase transition is extended, it is injected from the dew condensation surface 63 of the cold storage agent container 61 into the tank 31 of the mist generating unit 30. The amount of water to be increased.

  The area of the rear surface of the cool storage agent container 61 on the side of the heat absorbing surface 54 of the Peltier element 53 is set smaller than that of the heat absorbing surface 54 of the Peltier element 53. For this reason, heat is efficiently absorbed from the cool storage agent in the cool storage agent container 61 through the heat absorbing surface 54 and the heat radiating surface 55 of the Peltier element 53. And since the cool storage agent in the cool storage agent container 61 convects by a temperature difference, the whole cool storage agent comes to solidify.
