  A refrigerator outlet (not shown) is opened below the back of the refrigerator compartment 2, and a vegetable compartment inlet (not shown) is provided in the vegetable compartment 5. The refrigerator compartment outlet and the vegetable compartment inlet are connected by a passage (not shown) passing through the back surface of the temperature switching chamber 3 so that the refrigerator compartment 2 and the vegetable compartment 5 communicate with each other.

  A return air passage 19 communicating with the temperature switching chamber 3 extends downward from the temperature switching chamber return damper 20 and is disposed behind the temperature switching chamber 3 and the vegetable chamber 5. The air in the temperature switching chamber 3 is guided to the evaporator 17 through the return ventilation paths 19 and 21 by opening the temperature switching chamber return damper 20. In addition, a vegetable room outlet (not shown) communicating with the return ventilation path 19 is provided on the back of the vegetable room 5.

  In the refrigerator 1 having the above-described configuration, the cold air generated by the evaporator 17 moves up the cold air passage 31 as indicated by an arrow A by driving the blower 18 and is sent to the ice making chamber 4. The cold air sent to the ice making room 4 flows through the ice making room 4 and the freezing room 6 and flows out from the freezing room damper 22. And it returns to the evaporator 17 via the return ventilation path 21. As a result, the ice making chamber 4 and the freezing chamber 6 are cooled.

  The cold air branched at the upper portion of the cold air passage 31 by driving the blower 28 circulates through the cold air passage 32 as shown by an arrow B through the cold room damper 27 and is sent to the cold room 2. Further, as shown by an arrow C, the air flows through the introduction ventilation path 12 and is sent to the chilled chamber 23. The cold air sent to the refrigerator compartment 2 and the chilled compartment 23 flows through the refrigerator compartment 2 and the chilled compartment 23 and then flows into the vegetable compartment 5. The cold air flowing into the vegetable compartment 5 flows through the vegetable compartment 5 and returns to the evaporator 17 via the return passages 19 and 21. Thereby, the inside of the refrigerator compartment 2 and the vegetable compartment 5 is cooled, and if it becomes preset temperature, the refrigerator compartment damper 27 and the chilled compartment damper 23 will be closed.

  Further, the cold air branched at the upper portion of the cold air passage 31 by driving the blower 14 flows through the introduction ventilation path 12 and flows into the temperature switching chamber 3 via the temperature switching chamber discharge damper 13 as indicated by an arrow D. The cold air flowing into the temperature switching chamber 3 flows through the temperature switching chamber 3 and flows out from the outlet 33b. Then, as indicated by an arrow E, the vapor returns to the evaporator 17 via the return ventilation paths 19 and 21. Thereby, the inside of the temperature switching chamber 3 is cooled.

  As described above, the temperature switching chamber 3 can switch the room temperature by the user. For example, the user can select each temperature zone such as frozen (−15 ° C.), partial (−8 ° C.), chilled (−3 ° C.), refrigerated (3 ° C.), and vegetables (8 ° C.). . Thus, the user can store the stored product in a frozen state or a refrigerated state at a desired temperature. The indoor temperature can be switched by changing the amount of opening the temperature switching chamber discharge damper 13 and the air volume of the blower 14.

  At this time, the baffle 20a of the temperature switching chamber return damper 20 is disposed so as to open the opening 20b and close the opening 20c. For this reason, the cold air flowing in from the inflow port 33 a flows through the return ventilation path 19 via the temperature switching chamber return damper 20.

  For example, when the temperature switching chamber 3 is switched from the freezing indoor temperature to the refrigerated indoor temperature, the heater 15 may be energized to raise the temperature. Thereby, it can switch to desired room temperature rapidly. Further, by energizing the heater 15, the room temperature of the temperature switching chamber 3 is switched from the low temperature side where the stored items are stored frozen or refrigerated to the high temperature side where the cooked heated food is temporarily kept warm or cooked. Can be done.

  When the temperature of the temperature switching chamber 3 is set to the high temperature side, the temperature switching chamber discharge damper 13 is closed, and the baffle 20a of the temperature switching chamber return damper 20 is disposed at a position where the opening 20b is closed and the opening 20c is opened. Is done. When the heater 15 and the blower 14 are driven, the air sent from the blower 14 to the temperature switching chamber 3 flows out from the outflow port 33b, and is guided to the blower 14 through the temperature switching chamber return damper 20 and circulates.

  Accordingly, the temperature switching chamber 3 can be sealed to prevent warm air from flowing out, and the temperature distribution in the temperature switching chamber 3 on the high temperature side can be made uniform, and deformation, ignition, smoke generation, and the like around the heater 15 and the heater can be prevented. be able to. In addition, it is possible to provide a highly convenient refrigerator that does not require a heat-reserving chamber or the like for retaining the heated food, reduces the user's economic burden, and does not require the installation location of the heat-retaining chamber.

  Since the growth temperature of the main food poisoning bacteria is 30 ° C. to 45 ° C., the indoor temperature on the high temperature side is preferably set to 50 ° C. or more in consideration of the tolerance of the heater capacity, the temperature distribution in the temperature switching chamber 3, and the like. Thereby, propagation of miscellaneous bacteria can be prevented. Moreover, since the heat-resistant temperature of the general resin parts used for a refrigerator is 80 degreeC, when the room temperature of a high temperature side shall be 80 degrees C or less, it can implement | achieve cheaply.

  In order to sterilize food poisoning bacteria, for example, in the case of enterohemorrhagic E. coli (pathogenic E. coli O157), heating at 75 ° C. for 1 minute is required. Therefore, it is more preferable that the room temperature on the high temperature side is 80 ° C. in consideration of the tolerance of the heater capacity and the temperature distribution in the temperature switching chamber 3.

The following are the test results on the sterilization of food poisoning bacteria at 55 ° C. In the initial state, E. coli 2.4 × 10 ³ CFU / mL, Staphylococcus aureus 2.0 × 10 ³ CFU / mL, Salmonella 2.1 × 10 ³ CFU / mL, Vibrio parahaemolyticus 1.5 × 10 ³ CFU / ML, Cereus 4.0 × 10 ³ CFU / mL. This test sample was heated from 3 ° C. to 55 ° C. over 40 minutes, kept at 55 ° C. for 3.5 hours, then returned from 55 ° C. to 3 ° C. over 80 minutes, and the amount of each bacterium was examined again. As a result, all the bacteria were reduced to a level of 10 CFU / mL or less (not detected). Therefore, even if the set temperature on the high temperature side of the temperature switching chamber 3 is 55 ° C., there is a sufficient sterilization effect.

  A large stored item such as a cooked pot can be stored in the temperature switching chamber 3 by removing the mounting shelf 35. At this time, the mounting shelf 26 is stored along the ceiling wall 7 or the bottom wall 8 of the temperature switching chamber 3. A rail 41 parallel to the ceiling wall 7 is provided in the vicinity of the ceiling wall 7 at the upper portion of the side wall of the temperature switching chamber 3, and a locking portion 44 is provided at the front.

  As a result, the mounting shelf 26 can be supported and stored by the rails 42 and the locking portions 44 as indicated by a one-dot chain line 26 '. Therefore, the space between the rail 41 and the ceiling wall 7 constitutes a storage unit that stores the mounting shelf 26. The rail 42 may be formed by the upper surface of a groove recessed in the side wall of the temperature switching chamber 3.

  A recess 8 a is formed on the upper surface of the bottom wall 8 of the temperature switching chamber 3. By removing the storage case 11, the mounting shelf 26 can be stored in the recess 8 a as shown by a one-dot chain line 26 ″. As a result, the space between the storage case 11 and the bottom wall 8 can be stored in the mounting shelf 26. If the front of the recess 8a is opened so that the mounting shelf 26 can be taken in and out from the front, it is more desirable because the storage case 11 does not need to be removed.

  As described above, when the mounting shelf 26 is removed, the mounting shelf 26 is stored in the storage unit along the wall surface of the temperature switching chamber 3. Thereby, it is possible to store a small stored product by placing it on the mounting shelf 26 and to store a large stored product without losing the mounting shelf 26 without greatly reducing the volume of the temperature switching chamber 3. it can. Therefore, the convenience of the refrigerator 1 can be improved.
