The front wall 52a of the container part 52 is formed of a transparent resin, and the inside of the container part 52 is visible through the front wall 7b of the chilled chamber 7 and the front wall 52a of the container part 52.

  When the container portion 52 is stored in the chilled chamber 7, the upper surface of the container portion 52 is closed by the lid portion 51, and the back wall 52 c comes into contact with the back surface portion 60. A packing 56 is provided at the front end of the lid 51, and is in close contact with the front wall 52 a of the container 52. A packing 57 is provided on the back surface portion 60 and is in close contact with the back wall 52 c of the container portion 52.

  Opening portions 52e and 60a facing each other are opened in the back wall 52c of the container portion 52 and the fixing member 60. When the opening 60a is closed by a humidity control damper 55 described later, the storage container 50 is sealed.

  The peripheral wall including the lid portion 51 of the storage container 50 is filled with the cold storage material 100 except for the front wall 52a. The cold storage material 100 is made of water or a sodium chloride aqueous solution, and absorbs the temperature around the storage container 50. A humidity sensor 63 that detects the humidity in the storage container 50 is provided on the lower surface of the lid 51.

  A humidity control damper 55 is disposed in the opening 60a.

  In the refrigerator 1 having the above-described configuration, the cold air generated by exchanging heat with the cooler 18 by driving the compressor 41 is discharged to the refrigerating chamber 3, the chilled chamber 7, and the freezing chamber 4. Cool the chamber 4. The cold air flowing through the freezer compartment 4 returns to the cooler 18. The cold air flowing through the chilled room 7 and the refrigerated room 3 is guided to the vegetable room 5 through the return port 59, cools the vegetable room 5, and returns to the cooler 18.

  When the first contact surface 55d contacts the periphery of the opening 60a as shown in FIG. 4 by the rotation of the humidity control damper 55, the opening 60a is closed and the discharge port 58 is opened. Thereby, the inside of the storage container 50 is sealed, and the cold air discharged from the discharge port 58 to the chilled chamber 7 flows through the gap S around the storage container 50 as indicated by an arrow D1. And it flows out from the return port 59 as shown by the arrow D2. Thereby, drying in the storage container 50 is prevented and the stored product is cooled.

  At this time, the cold energy of cold air is stored in the cool storage material 100 of the storage container 50. For this reason, when the ambient temperature of the chilled chamber 7 rises due to the opening of the door 3 b of the refrigerator compartment 3, the temperature rise in the storage container 50 is prevented by the cold heat released from the cold storage material 100. Therefore, the temperature change of the surrounding cold air can be absorbed by the cold storage material 100, and the temperature in the storage container 50 can be kept constant.

  When the humidity in the storage container 50 becomes higher than a predetermined humidity due to moisture evaporated from the stored material, the humidity control damper 55 is rotated by the detection of the humidity sensor 63. Thereby, as shown in FIG. 5, the opening part 60a is opened, and the inside and outside of the storage container 50 communicate with each other through the opening parts 60a and 52e. The cold air discharged from the discharge port 58 flows into and out of the storage container 50 through the openings 60a and 52e as indicated by an arrow D3. For this reason, when the humidity in the storage container 50 decreases and becomes lower than the predetermined humidity, the opening 60a is closed as shown in FIG. Therefore, the inside of the storage container 50 can be conditioned, and deterioration of stored items due to contact with condensed water can be prevented.

  In addition, it may replace with the humidity sensor 63 and you may provide the detection sensor which detects opening / closing of the timer and the storage container 50. FIG. Thereby, it is possible to determine whether or not the inside of the storage container 50 has become higher than the predetermined humidity by the elapsed time after opening and closing the storage container 50.

  The humidity control damper 55 rotates as shown in FIG. 6 when the cooling of the chilled chamber 7 is stopped by closing the temperature control damper 16 or when the cooler 18 is defrosted. That is, the second contact surface 55e contacts the periphery of the opening 60a, and the third contact surface 55f contacts the periphery of the discharge port 58. Thereby, the inside of the storage container 50 is sealed, and the discharge port 58 is closed to prevent the cold air having a high temperature from being discharged into the chilled chamber 7. At this time, the cooled cool storage material 100 absorbs the temperature change of the surrounding cold air, and the temperature rise in the storage container 50 is prevented. Therefore, the temperature in the storage container 50 can be kept constant.

  According to the present embodiment, the storage container 50 is formed so as to be hermetically sealed, and has a gap S through which cool air flows between the storage container 50 and the inner wall of the chilled chamber 7, and the cold storage material 100 is provided on the peripheral wall of the storage container 50. Therefore, the regenerator material 100 can absorb changes in the surrounding temperature and keep the temperature in the storage container 50 constant. Further, since the storage container 50 is hermetically sealed, it is possible to suppress the drying of the stored product and maintain the freshness of the stored product.

  Further, the opening 60a provided in the storage container 50 opens the opening 60a when the storage container 50 becomes higher in humidity than the predetermined humidity. Therefore, the storage container 50 is conditioned to prevent deterioration of stored items. it can.

  Further, the humidity control damper 55 can open and close the discharge port 58 that discharges cold air to the chilled chamber 7 with the opening 60a closed, and removes the cooler 18 that generates cold air when the cooling of the chilled chamber 7 is stopped. Since the discharge port 58 is closed by the humidity control damper 55 during frosting, the inflow of high-temperature cold air from the discharge port 58 and the opening 60a can be blocked to reduce deterioration of stored items.

  Further, when the opening 60a is blocked by the first contact surface 55d of the humidity control damper 55 supported by the storage container 50, the discharge port 58 is opened, and the opening 60a is blocked by the second contact surface 55e. At this time, the discharge port is closed by the third contact surface 55f. Thereby, it can implement | achieve easily that the drying of a stored matter is suppressed and a freshness is maintained.

  Further, since the front wall 52a of the storage container 50 is made of a transparent member and the cold storage material 100 is arranged on the peripheral wall excluding the front wall 52a, the visibility inside the storage container 50 can be improved and the occurrence of condensation can be suppressed. .

  Moreover, since the cool storage material 100 is the water or sodium chloride aqueous solution enclosed with a surrounding wall, heat capacity is large and the freezing temperature is about -1 degreeC-0 degreeC. For this reason, the stored product can be stored without freezing. Water or a sodium chloride aqueous solution is easily available, and there is no danger even if it leaks into the refrigerator compartment 3, and cleaning is easy.

  Further, the storage container 50 has a box-shaped container part 52 whose upper surface is opened and a lid part 51 that closes the upper surface of the container part 52. The lid part 51 is fixed to the chilled chamber 7, and the container part 52 is arranged in the front-rear direction. Slide to. For this reason, the storage container 50 which can be sealed with the clearance S between the inner wall of the chilled chamber 7 can be easily realized.
