Further, a vent hole 66 is formed below the upper casing 19 in the left and right side wall portions 18b of the lower casing 18.

Further, in the refrigeration cycle of the present embodiment, although not shown, a switching valve is provided. By the switching valve, the refrigerant discharged from the compressor 31 can be switched to the case of being supplied to the side of the refrigerating cooler 37 or the side of the refrigerating cooler 47.

A control device 68 as a control unit is provided in a portion of the refrigerator 1 near the lower portion of the back surface. The control device 68 is configured by a microcomputer (microcomputer), a timer, a memory device, and the like (not shown). An operation panel 16 as an input/output device or a freezer compartment temperature sensor 33A as a sensor device is connected to the control device 68. Further, the refrigerator compartment temperature sensor 33B, the vegetable compartment temperature sensor 33C, and the like are connected to the control device 68. The control device 68 has a function of a compressor 31 or a switching valve, a defrosting heater 38, an automatic ice making device 10, a cooling blower 39, and a refrigerating cycle based on the signals and a predetermined control program. The cooling blower 52, the damper 49, the sterilization component generating device 55, and the like are controlled.

Next, the action of the above configuration will be described.

The compressor 31 that drives the refrigeration cycle drives the refrigeration blower 39 in a state where the refrigerant is supplied to the freezing cooler 37. In this way, the cold air cooled by the freezing cooler 37 is supplied from the freezing cold air supply port 40 to the ice making chamber 8, the small freezing compartment, and the freezing compartment 9, thereby making the ice making compartment 8, the small freezing compartment, And the freezing compartment 9 is cooled. The air in the ice making chamber 8, the small freezing compartment, and the freezing compartment 9 is finally sucked into the freezing cooler chamber 35 from the suction port 41, and is again cooled by the freezing cooler 37. cycle.

In the compressor 31 that drives the refrigeration cycle, the refrigerating blower 52 is driven in a state where the refrigerant is supplied to the refrigerating cooler 47 and the damper 49 of the refrigerating cold air duct 44 is opened. In this way, the cold air cooled by the refrigerating cooler 47 is supplied to the cold air supply port 48 from the refrigerating cold air tank 44 to the cold. Inside the compartment 6 (see the hollow arrow in Figure 1). After the cold air supplied to the refrigerator compartment 6 is cooled by the stored matter in the refrigerator compartment 6, the vegetable compartment is supplied from the lower vegetable compartment to the vegetable compartment 7 by the cold air supply port 13, and the stored matter in the vegetable compartment 7 is cooled.

At this time, the vegetable compartment cold air supply port 13 is located at a position avoiding the upper surface opening of the upper casing 19. Specifically, the vegetable compartment cold air supply port 13 is located rearward of the upper surface opening of the upper casing 19 and facing downward, and is disposed at a position that does not face the upper surface opening of the upper casing 19. Therefore, the cold air supplied into the vegetable compartment 7 from the vegetable compartment cold air supply port 13 is not directly sprayed to the egg placement member 22 in the upper casing 19. Then, the air in the vegetable compartment 7 is sucked into the air supply duct 46 from the return port 51, and then returned to the refrigerating cooler chamber 45, and is again cooled by the refrigerating cooler 47.

Here, in the vegetable compartment 7, when the egg 61 is placed in the egg arranging member 22 in the upper casing 19, the egg 61 is also cooled. At this time, even if the egg 61 is disposed in all of the egg arrangement holes 59 of the two egg arrangement members 22, the vent holes 60 are provided in the upper wall 57 of the egg arrangement member 22. Therefore, air can flow between the space above the egg arrangement member 22 and the space portion 63 which is the inside of the egg arrangement member 22 (see an arrow A1 in Fig. 3). Further, since the space portions 63 of the two adjacent egg laying members 22 in the upper casing 19 communicate with each other via the notch portion 62 of the hanging wall 58, air can also flow between them (see FIG. 3). Arrow A2).

Further, vent holes 64 are provided in the left and right side wall portions 19b of the upper casing 19. The vent hole 64 communicates with the gap 65 between the side wall portion 19b and the side wall portion 18b of the lower case 18, and also communicates with the space portion 63 via the notch portion 62 of the hanging wall 58. Therefore, air can also flow between the space portion 63 and the lower casing 18 (see an arrow A3 in Fig. 3). Further, a vent hole 66 is provided in the side wall portion 18b of the lower case 18. Thereby, air can also flow between the inside and the outside of the lower case 18 (see an arrow A4 in Fig. 3).

Further, in the above configuration, the deodorizing device 54 is provided beside the vegetable room cold air supply port 13. Therefore, the odor component contained in the air supplied from the refrigerator compartment 6 to the vegetable compartment 7 side is adsorbed and removed by the deodorizing device 54. Further, a sterilization component generating device 55 is provided above the upper casing 19. Therefore, the sterilization component (fine particle water) generated by the sterilization component generating device 55 is supplied to the egg 61 in the upper casing 19. Thereby, the surface of the egg 61 is sterilized. Further, it is expected that the bacteria adhering to the egg 61 can be prevented from adhering to other vegetables or the like contained in the vegetable compartment 7.

At this time, the temperature in the vicinity of the egg arrangement member 22 is detected by the vegetable compartment temperature sensor 33C, and the control device 68 controls the damper 49 such that the temperature in the vicinity of the egg arrangement member 22 reaches a temperature suitable for preserving the egg. Specifically, control is performed such that if the detected temperature of the vegetable compartment temperature sensor 33C falls and reaches the preset lower limit set temperature, the damper 49 is switched to the closed state to suppress the temperature drop of the vegetable compartment 7. On the other hand, when the detected temperature of the vegetable compartment temperature sensor 33C rises to reach the preset upper limit set temperature, the damper 49 is switched to the open state to cool the vegetable compartment 7 again.

According to the above embodiment, the following effects can be obtained.

The vegetable compartment 7 is configured such that an egg capable of arranging a plurality of eggs 61 is disposed in the upper casing 19 provided in the upper portion of the lower casing 18 that can be taken out. The member 22 is configured. Since the upper case 19 of the vegetable compartment 7 has a large width and a large storage area, the storage capacity of the egg 61 disposed in the egg placement member 22 can be ensured in a large amount. Moreover, the egg 61 can be easily taken out by taking the egg arranging member 22 together with the upper case 19.

Since the egg arranging member 22 is disposed over substantially the entire surface of the inner bottom surface of the upper casing 19, the capacity of the egg 61 can be more ensured. At this time, although two egg arrangement members 22 are arranged, one egg arrangement member having a size equivalent to the two egg arrangement members 22 described above may be used.

The egg arranging member 22 is configured such that there are a plurality of the egg arranging members 22, and the two egg arranging members 22 are arranged side by side in the lateral direction of the upper case body 19 in the horizontal direction. Thereby, for example, as shown in FIG. 4, one egg placement member 22 (the egg arrangement member 22 on the right side in FIG. 4) of the two egg arrangement members 22 is arranged upside down. Thereby, the inverted egg placement member 22 can also accommodate articles other than eggs. Further, by taking out one of the egg arranging members 22 from the upper casing 19, it is possible to accommodate articles other than eggs in the space. The configuration of the two egg fitting members 22 is not limited to being arranged side by side in the lateral direction of the right and left, and may be arranged side by side in the lateral direction of the front and rear. Further, the egg arrangement member 22 is not limited to two, and may be three or more.

Each of the two egg placement members 22 is configured such that a space portion 63 is formed between each of the two egg placement members 22 and the inner bottom surface of the upper casing 19, and two adjacent egg placement members 22 are formed. The space portions 63 are in communication with each other. Thereby, the air in the vicinity of the egg arrangement member 22 is hard to stagnant, and the air in the vicinity of the egg 61 easily flows. Moreover, when one of the two egg arranging members 22 is inverted, In use, the upper side of the inverted egg arrangement member 22 forms a space portion 63. Further, the space portion 63 of the inverted egg arrangement member 22 is configured to communicate with the space portion 63 of the egg placement member 22 that is not inverted. Thereby, even when one egg arrangement member 22 is used upside down, the air in the vicinity of the egg arrangement member 22 is hard to be stagnated, and the air in the vicinity of the egg 61 easily flows (refer to an arrow A5 in Fig. 4).

Sometimes, the shell of the egg 61 may be broken to cause the contents to flow out or adhere to the shell of the egg 61 to fall. On the other hand, the bottom wall portion 19a of the upper casing 19 is not provided with a hole penetrating in the vertical direction. Thereby, even if the contents of the egg 61 are discharged or the attached matter is dropped, the contents or the deposits can be prevented from falling into the lower case 18 from the upper case 19, and the like can be prevented from adhering to the lower case. Vegetables in 18 are waiting.

Further, the configuration is such that only one cooler is used, and the storage compartment of the freezing temperature zone and the storage compartment of the refrigerating temperature zone are cooled by the one cooler.

Specifically, in the inside of the heat insulating box 2 of the refrigerator 1, the refrigerator compartment 6, the freezing compartment 9, and the vegetable compartment 7 are provided in order from the top. An insulating partition wall 70 is provided between the refrigerating compartment 6 and the freezing compartment 9. An insulating partition wall 71 is also provided between the freezing compartment 9 and the vegetable compartment 7. Further, at the rear of the freezing compartment 9, a duct member 72 is provided as shown in Fig. 9(a). The cooler chamber 73 is formed by the duct member 72. A cooler 74, a defrosting heater 75, and a blower 76 are attached to the cooler chamber 73. A freezing cold air supply port 77 is formed in an upper portion of the duct member 72, and a suction port 78 is formed in a lower portion of the duct member 72.

A duct member 79 for a refrigerating compartment is provided at the rear of the refrigerating compartment 6. The cold air duct 80 for refrigeration is formed by the duct member 79 for a refrigerator. The cold air duct 80 for refrigeration is extended in the up-down direction. The lower end portion of the cold air duct 80 for refrigeration is connected to the cooler chamber 73. The cold air supply port 81 for refrigeration is formed in a plurality of locations on the duct member 79 for the refrigerator compartment. A damper 82 is provided at a portion where the cold air duct 80 for refrigeration and the cooler chamber 73 are connected. The damper 82 opens and closes the cold air duct 80 for refrigeration.

A predetermined portion of the lower portion of the duct member 79 for the refrigerator compartment is formed with a suction port 83 as shown in Fig. 9(b). Further, as shown in FIG. 9(b), a predetermined portion of the rear portion of the freezing compartment 9 is provided with a vegetable compartment duct 84. The vegetable compartment duct 84 extends in the vertical direction while avoiding the freezing compartment 9, and the upper end portion communicates with the suction port 83. The lower end portion of the vegetable compartment duct 84 serves as a vegetable compartment cold air supply port 85. The vegetable compartment cold air supply port 85 is disposed at the rear of the vegetable compartment 7 and is located behind the lower casing 18 and the upper casing 19. Therefore, the vegetable compartment cold air supply port 85 is disposed at a position avoiding a position facing the upper surface opening of the upper casing 19, and does not face the upper casing 19 Upper surface opening. The heat insulating partition wall 71 on the upper side of the vegetable compartment 7 is provided with a return duct 86 as shown in Fig. 9(a). The opening of the return duct 86 on the side of the vegetable compartment 7 serves as a return port 87. The upper end portion of the return duct 86 communicates with the cooler chamber 73.

The vegetable compartment 7 is of a draw-out type as in the first embodiment, and the lower case 18 and the upper case 19 are attached to the inside. In the upper casing 19, the egg arranging member 22 is disposed in a releasable manner. Further, on the lower surface of the heat insulating partition wall 71 as the top plate of the vegetable compartment 7, a vegetable compartment temperature sensor 33C and a sterilization component generating device 55 are provided above the upper casing 19. Further, in the refrigerator 1 of the fourth embodiment, only the freezing compartment 9 is the storage compartment of the freezing temperature zone. In addition to the configuration, a freezing chamber 9 is provided between the refrigerator compartment 6 and the vegetable compartment 7, and an ice making compartment and a small freezing compartment are provided in the same manner as in the first embodiment. In this embodiment, the compressor 31, the defrosting heater 75, the blower 76, the damper 82, the sterilization component generating device 55, and the like are also controlled by the above-described control device 68.

In the above configuration, when the blower 76 is driven in a state where the damper 82 is closed, the cold air cooled by the cooler 74 is supplied from the freezing cold air supply port 77 to the freezer compartment 9. Thereby, the cold air in the freezing compartment 9 is circulated so as to return to the inside of the cooler chamber 73 from the suction port 78, and the freezing compartment 9 is cooled.

Further, the blower 76 is driven in a state where the damper 82 is opened. At this time, a part of the cold air cooled by the cooler 74 is supplied into the refrigerating crucible 6 from each of the refrigerating cold air supply ports 81 via the refrigerating cold air duct 80, whereby the inside of the refrigerating compartment 6 is cooled. Further, the remaining portion of the cold air cooled by the cooler 74 is supplied into the freezing chamber 9 as described above. The cold air that has been cooled in the refrigerating compartment 6 is taken from the lower suction port 83 After the vegetable chamber is ejected from the side of the duct 84, the inside of the vegetable compartment conduit 84 flows downward, and is supplied from the vegetable compartment to the vegetable compartment 7 by the cold air supply port 85, and the inside of the vegetable compartment 7 is cooled. At this time, the egg 61 accommodated in the upper case 19 is also cooled. The cold air cooled in the vegetable compartment 7 is returned from the return port 87 to the cooler chamber 73 via the return duct 86.

Also in the above embodiment, substantially the same operational effects as those of the first embodiment can be obtained. In this embodiment, the freezing compartment 9 which is a storage compartment of the freezing temperature zone is disposed, and the refrigerating compartment 6 is disposed above and the vegetable compartment 7 is disposed below. Then, the cold air cooled by the one cooler 74 is separately supplied to the freezing compartment 9 and the refrigerating compartment 6, and the cooled cold air of the refrigerating compartment 6 is supplied to the vegetable compartment 7. According to this configuration, since the heat insulating partition wall 71 is provided between the vegetable compartment 7 and the freezing compartment 9, it is possible to prevent the vegetable compartment 7 from being excessively cooled by the influence of the freezing compartment 9. That is, since the vegetable compartment 7 is adjacent to the freezing compartment 9 of the freezing temperature zone, it is likely to be cooled, but this embodiment can suppress the influence.

Moreover, the cold air cooled by the cooler 74 must be lowered to a temperature suitable for the cooling of the freezing compartment 9. Therefore, the cold air cooled by the cooler 74 is lower than the temperature cooled by the refrigerating cooler 47 in the first embodiment. If the cold air having a low temperature is passed through the refrigerating compartment 6 and then directly supplied to the egg 61 in the vegetable compartment 7, the egg 61 may be excessively cooled. On the other hand, in the present embodiment, the vegetable compartment cold air supply port 85 is not directed to the upper surface opening of the upper casing 19 in which the egg 61 is placed. Therefore, it is possible to prevent the cold air supplied from the vegetable compartment cold air supply port 85 to the vegetable compartment 7 from being directly blown onto the egg 61, thereby preventing the egg 61 from being too cold.

As described above, the vegetable compartment of the refrigerator of the present embodiment includes a lower casing that can be withdrawn and an upper casing that is provided at an upper portion of the lower casing. Upper case Inside, an egg arranging member capable of arranging a plurality of eggs is disposed in a removable manner. Thereby, the egg's capacity can be increased, and the egg can be easily taken.
