  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the operation of the refrigeration cycle will be described. The refrigeration cycle is operated by a signal from a control board (not shown) according to the set temperature in the cabinet, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 12 is condensed to some extent by a condenser (not shown), and further disposed on the side surface and back surface of the refrigerator 21 main body and the front opening of the refrigerator 21 main body. The refrigerant 21 is condensed and liquefied through a refrigerant pipe (not shown) while preventing condensation of the main body of the refrigerator 21 and reaches a capillary tube (not shown). Thereafter, the capillary tube is depressurized while exchanging heat with a suction pipe (not shown) to the compressor 12, and becomes a low-temperature and low-pressure liquid refrigerant and reaches the cooler 74. Here, the low-temperature and low-pressure liquid refrigerant exchanges heat with air by the operation of the cooling fan 75, and the refrigerant in the cooler 74 evaporates.

  Then, cool air for cooling each chamber is generated in the cooling chamber 71, and the generated cool air is sent to each chamber. For example, it is sent to the refrigerating room through the conveying air passage 72 via a refrigerating damper (not shown). Moreover, it is sent to the storage room via a low temperature damper (not shown). Thereby, cooling control is performed to a predetermined temperature for each chamber.

  In the present embodiment, the low temperature air passage 95 does not intersect the center line AA of the dew condensation prevention heater 55 on the vertical projection plane, that is, the dew condensation prevention heater 55 and the low temperature air passage side wall 94. This distance L1 is longer than the distance L2 between the condensation prevention heater 55 and the back surface of the storage chamber 63. For this reason, compared with the case where the low temperature air passage 95 is provided so as to intersect the center line AA of the condensation prevention heater 55 on the vertical projection plane, the dew condensation prevention to the cold air flowing through the low temperature air passage 95 is achieved. The thermal effect of the heater 55 can be reduced. In the low-temperature air passage 95, cold air having a uniform temperature distribution flows, and the temperature distribution in the low-temperature storage chamber 63 does not become non-uniform.

In particular, when the storage chamber 63 is a low temperature chamber in a minus temperature zone, a part of the storage chamber 63 does not become a plus temperature zone due to the heat effect of the dew condensation prevention heater 55. The possibility that the freshness deteriorates, such as part of the stored food being melted, can be reduced. The effect that the temperature distribution in the storage chamber 63 becomes uniform becomes greater as the set temperature in the storage chamber 63 is lower. The storage chamber 63 may be a switching chamber in which a low temperature chamber in a minus temperature zone and a chilled chamber in a plus temperature zone can be switched. In this case, it is possible to obtain an effect that the temperature distribution in the low temperature storage chamber 63 becomes uniform, and it is possible to select a temperature range suitable for the food to be stored, and the usability of the user is improved.

  Further, since the dew condensation prevention heater 55 is closer to the conveyance air path 72 than the low temperature air path 95, the heat of the dew condensation prevention heater 55 is compared with the heat to the conveyance air path 72 than the low temperature air path 95. Although the influence becomes large, the air passage cross-sectional area of the conveyance air passage 72 is large, and the cold air conveyed is discharged into the refrigerating chamber 22 having a larger internal volume than the low-temperature storage chamber 63, so the temperature in the refrigerating chamber 22 is increased. The distribution is not greatly affected.

  Further, in the present embodiment, the low temperature air passage 95 through which the cool air for the storage chamber 63 flows is formed inside the transport air passage 72 through which the cold air for the refrigerator compartment 22 flows. Even if the wall thickness of the air passage is reduced, the cold air flowing through the low temperature air passage 95 has a uniform temperature distribution compared to the case where the air passage 95 is formed separately, and the temperature distribution in the storage chamber 63 is reduced. Does not become non-uniform.

Yes.

  On the connection side of the top surface air passage 97 with the front low temperature air outlet 88, a top surface air passage inclined portion 97a is provided. As a result, the cold air flowing into the top surface duct unit 96 from the front low temperature air outlet 88 flows so as to rise to the top surface side, then flows in the front-rear direction of the storage chamber 63, and from the plurality of top surface air outlets 98. It flows into the storage chamber 63.

  The bottom side of the storage chamber 63 is formed by a storage chamber lower case 65. A case inclined portion 65 a is provided on the back side of the storage chamber lower case 65. For this reason, the cold air circulated in the storage chamber 63 rises from the bottom surface of the storage chamber lower case 65 toward the lower portion of the front low temperature outlet 88 and then flows downward.

In the present embodiment, since the storage chamber 63 does not intersect the center line AA of the condensation prevention heater 55 on the vertical projection plane, the distance between the storage chamber 63 and the condensation prevention heater 55 is increased. Therefore, the thermal influence of the dew condensation prevention heater 55 on the storage chamber 63 is reduced, and the temperature distribution in the low temperature storage chamber 63 does not become uneven. In particular, since the left heat insulating wall 62a of the storage chamber 63 is provided so as to face the center line AA of the condensation prevention heater 55, the thermal influence on the storage chamber 63 of the condensation prevention heater 55 can be greatly reduced.

  Furthermore, by providing the storage chamber 63 on the second door 31b side where the partition 53 is not provided, the storage chamber 63 can be provided further away from the dew condensation prevention heater 55. The temperature distribution does not become uneven. Furthermore, since the front door 64 of the storage chamber 63 can be opened and closed simply by opening the second door 31b without opening the first door 31a, the usability of the user is improved.

  Moreover, the accessory case 101, the egg storage container 102, and the water storage tank 103 are provided in the 1st door 31a side with a small opening area. Since the small container 101, the egg storage container 102, and the water storage tank 103 that are likely to be frequently taken out can be taken out only by opening the first door 31a without opening the second door 31b. By opening the second door 31b, it is possible to prevent the temperature distribution in the storage chamber 63 from becoming uneven.

  In addition, since the top surface of the storage chamber 63 is provided with a plurality of top air outlets 98 in the depth direction of the storage chamber 63, the cold air flowing into the low temperature air passage 95 from the transport air passage 72 is stored. Since it flows in from the top front of the chamber 63 or the center of the top surface, the temperature distribution in the storage chamber 63 does not become uneven. In addition, after the cold air circulated in the storage chamber 63 rises from the bottom surface of the storage chamber lower case 65 toward the lower portion of the front low temperature air outlet 88 and flows downward, a large amount of food is stored in the storage chamber 63. Even in such a case, since the temperature distribution does not become non-uniform, it is possible to achieve both the improvement of the storage property in the storage chamber 63 and the uniform temperature distribution.

  As described above, the refrigerator according to the present invention has the first and second doors at the opening of the refrigerator compartment, and even if a cold storage compartment is provided inside the refrigerator compartment, the temperature distribution in the storage compartment is uniform. Therefore, it can be applied to various types and sizes of refrigerators for home use and business use.
