In addition, the lower end of the cold air passage 18 in the refrigeration temperature zone is connected to the cold air hole 10c (see FIG. 5( b )) formed above the first region 10a1 of the duct cover 10a.

In other words, the refrigerated temperature zone cold air passage 18 has a function of guiding the cold air 100 generated by the cooler 12 to the refrigerated compartment 3 and the chilled fresh compartment 4 (refrigerated temperature zone compartment).

In addition, it is preferable not to form the cold air passage 18 in the refrigeration temperature zone and the refrigeration discharge port 18a at the position of the vegetable compartment 5. With this configuration, the cold air 100 that circulates in the cold air passage 18 in the refrigeration temperature zone is not supplied to the vegetable compartment 5. structure. Moreover, the vegetable compartment 5 is not directly cooled by the cold air 100 but is indirectly cooled as will be described later.

In addition, illustration of the inner wall 1b (refer FIG. 3) is abbreviate|omitted in FIG. The inner wall 1b is configured to cover the periphery of the refrigerator compartment 3, the chilled compartment 4, the vegetable compartment 5, and the freezer compartment 6 except for the front. In addition, the rear side and the left-right direction of the cooler room 10 are surrounded by the inner wall 1b.

In addition, the inner wall 1b constitutes the tubular cold air passage 18 for the refrigeration temperature zone so as to close the groove-shaped cold air passage 18 for the refrigeration temperature zone from the rear.

And, at the rear of the vegetable compartment 5, a fixed plate 10b for installing a cooling blower fan 11a and a freezing blower fan 11b is arranged, and the front of the fixed plate 10b is covered by the tunnel cover 10a, and the rear of the freezer compartment 6 is covered by a back plate 1f. And the rear cover 1d is separated from the cooler chamber 10 .

Moreover, it includes a blower fan 11 (a blower fan 11a for refrigeration, a blower fan 11b for freezing), a cooler 12, a cold air passage 18 for a refrigeration temperature zone, a refrigerating outlet 18a, a cold air passage 19 for a freezer temperature zone, and a freezer discharge outlet. The outlet 19a constitutes the cooling mechanism of this embodiment.

As shown in Figure 6 (a), a tunnel cover 10a is arranged in front of the cooling fan 11a (discharge side So), and the first area 10a1 covered by the tunnel cover 10a is connected to the top extending through the cold air hole 10c. The refrigerated temperature zone communicates with the cold air passage 18 . Moreover, the rear side (intake side Si) of the ventilation fan 11a for refrigeration is arrange|positioned so that it may face the cooler room 10. As shown in FIG. With this structure, the ventilation fan 11a for refrigeration can send the cold air 100 generated by the cooler 12 into the cold air flow path 18 in the refrigeration temperature zone. Then, the cold air 100 sent to the cold air passage 18 in the refrigeration temperature zone by the ventilation fan 11 a for refrigeration is exhausted from the refrigeration outlet 18 a and supplied to the refrigerator compartment 3 and the chilled compartment 4 . In other words, cool air 100 is supplied to refrigerator compartment 3 and chilled compartment 4 from behind.

In addition, as shown in FIG. 6 (b), a tunnel cover 10a is arranged in front (discharge side So) of the ventilation fan 11b for freezing, and the second region 10a2 of the internal space covered by the tunnel cover 10a and the second area 10a2 formed at the bottom are connected. The freezing temperature zone communicates with the cold air passage 19. Moreover, the rear side (intake side Si) of the ventilation fan 11b for freezing is arrange|positioned so that it may face the cooler room 10. As shown in FIG. With this configuration, the freezing air blower fan 11 b can send the cold air 100 generated by the cooler 12 into the cold air passage 19 in the freezing temperature zone. The freezing air blower 11b discharges the cold air 100 generated by the cooler chamber 10 obliquely upward, and the obliquely upwardly discharged cold air 100 is deflected downward by the tunnel cover 10a and flows into the freezing temperature zone cold air passage 19 . Then, the cold air 100 sent to the freezing temperature zone cold air passage 19 by the freezing air blower fan 11b is discharged from the freezing discharge port 19a and supplied to the freezing compartment 6 . In other words, cool air 100 is supplied to freezer compartment 6 from behind.

Moreover, as shown in FIG. 6(a) and FIG. 6(b), it is preferable that the installation angle θ1 of the ventilation fan 11a for refrigeration is smaller than the installation angle θ2 of the ventilation fan 11b for freezing.

The installation angle mentioned here is the angle formed by the discharge direction of the cool air 100 and the up-down direction, and the smaller the installation angle is, the more the cool air 100 is discharged upward.

In other words, the ventilation fan 11a for refrigeration is preferably attached at an installation angle such that the cold air 100 is discharged upward compared with the ventilation fan 11b for freezing. And the cooling blower fan 11a whose installation angle θ1 is smaller than the installation angle θ2 of the freezing blower fan 11b discharges the cold air 100 upward more than the freezing blower fan 11b.

Therefore, the air blower fan 11a for refrigeration with a small installation angle can send cold air 100 suitably with respect to the refrigeration temperature zone cold air flow path 18 extended upward.

Moreover, the ventilation fan 11b for freezing with a large installation angle can send cold air 100 suitably with respect to the freezing temperature zone cold air flow path 19 extended downward.

In addition, as shown in Fig. 4 and Fig. 5 (a), the ventilation fan 11a for refrigeration of the present embodiment and the ventilation fan 11b for freezing are arranged side by side, and are arranged in the partition wall 5a between the vegetable compartment 5 and the freezer compartment 6. higher up. Moreover, it is preferable to arrange|position the ventilation fan 11a for refrigeration in the upper position rather than the ventilation fan 11b for freezing.

In other words, it is preferable that the uppermost part of the flow of the cool air 100 discharged from the refrigeration blower fan 11a is located above the uppermost part of the flow of the cold air 100 discharged from the freezer blower fan 11b. The blower fan 11a and the blower fan 11b for freezing.

The ventilation fan 11a for refrigeration is a fan that sends the cold air 100 supplied to the refrigerator compartment 3 and the chilled compartment 4 arranged above the partition wall 5a. The flow path length of the cool air 100 is shortened, and the efficiency of supplying the cool air 100 to the refrigerator compartment 3 and the chilled compartment 4 can be improved. Furthermore, the refrigerator compartment 3 and the chilled compartment 4 can be efficiently cooled.

In addition, when both the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing are fans having a rectangular outer frame facing from the discharge side So, the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing 11b are installed so as to have a predetermined inclination angle with respect to the left-right direction from the front-rear direction, and preferably have different inclination angles with respect to the left-right direction.

In this embodiment, the inclination angle of the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing is such that the outer frames of the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing facing from the front or the rear are relative to the left-right direction. angle of inclination.

For example, as shown in FIG. 7 , an angle θ3 formed by a side of the upper (or lower) side of the outer frame facing from the front with respect to the left-right direction of the refrigeration blower fan 11 a having a rectangular outer frame is defined as the refrigeration blower fan 11 a. the angle of inclination. Similarly, an angle θ4 formed with respect to the left-right direction by the upper (or lower) side of the outer frame facing from the front of the freezing blower fan 11b having a rectangular outer frame is defined as the inclination angle of the freezing blower fan 11b.

In addition, in the present embodiment, the inclination angle θ3 of the cooling air-sending fan 11a is different from the inclination angle θ4 of the freezing air-sending fan 11b. For example, as shown in FIG. 7 , angle θ4 (inclination angle of freezing blower fan 11 b ) is larger than angle θ3 (inclination angle of refrigeration blowing fan 11 a ) (angle θ4 > angle θ3 ).

When the inclination angle θ3 of the ventilation fan 11a for refrigeration is equal to the tilt angle θ4 of the ventilation fan 11b for freezing (angle θ3=angle θ4), there is vibration of the ventilation fan 11a for refrigeration and the vibration of the ventilation fan 11b for freezing. The vibration of the fixed plate 10b is transmitted to the fixed plate 10b with the same transmission characteristics and resonates with each other, and the vibration of the fixed plate 10b increases. In this case, problems such as increased noise of refrigerator 1 (see FIG. 1 ) may occur.

As shown in FIG. 7 , the inclination angle θ3 of the air blower fan 11a for refrigeration is defined different from the inclination angle θ4 of the air blower fan 11b for freezing, so that the vibration of the air blower fan 11a for refrigeration and the vibration of the air blower fan 11b for freezing can be changed. The vibration transmission characteristic of the vibration to the fixed plate 10b can suppress the resonance of the vibration of the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing. Thereby, the vibration of the fixing plate 10b can be suppressed, and the noise of the refrigerator 1 (refer FIG. 1) can be reduced further.

In addition, the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing are respectively installed to have inclination angles θ3 and θ4, thereby avoiding interference in the left-right direction between the ventilation fan 11a for refrigeration and the ventilation fan 11b for freezing, thereby enabling The blower fan 11a for refrigeration and the blower fan 11b for freezing which are large in size are installed.

Moreover, the refrigerator 1 of this Example is equipped with the cooling mechanism for indirect cooling of the vegetable compartment 5. As shown in FIG.

8 is a side sectional view showing the structure of the chiller compartment and the vegetable compartment, FIG. 9 is a rear perspective view showing the cold air duct, FIG. 10 is a perspective view showing the structure of the partition wall, and FIG. 11 is a side sectional view showing the structure of the freezer compartment.

As shown in FIG. 8 , the chilled compartment 4 of this embodiment is disposed above the vegetable compartment 5 and separated from the vegetable compartment 5 by a partition 4 c, and the vegetable compartment 5 is formed to protrude forward from the chilled compartment 4 . And the partition part 4c becomes the bottom surface of the chilled compartment 4. As shown in FIG.

As mentioned above, the chilled compartment 4 is formed as the space partitioned by the lower storage shelf 3b, the partition part 4c, and the inner wall 1b.

Moreover, the vegetable compartment 5 is formed so that the vegetable container 50 which can be drawn forward is accommodated in the space partitioned by the partition part 4c, the partition wall 5a, and the inner wall 1b. In addition, the vegetable container 50 is formed with a handle portion 51 for holding hands of the user when pulling out the vegetable container 50 .

Preferably, the vegetable container 50 can be pulled out by sliding movement in the front-rear direction due to the rotation of the roller member 52 attached to the partition wall 5 a, so that the partition wall 5 a does not directly contact the vegetable container 50 .

In addition, a roller member (not shown) may be provided on the rear side of the vegetable container 50, for example, on the side of the vegetable container 50, and the roller member may roll on the upper surface of the partition wall 5a.

Moreover, the rear of the chilled compartment 4 is equipped with a refrigeration temperature band cold air passage 18, and is formed with a refrigeration outlet 18a communicating with the refrigeration temperature band cold air passage 18 and the chilled fresh compartment 4. The cold air 100 circulating in the refrigerator is supplied from the refrigeration outlet 18a to cool the chilled compartment 4 .

In addition, as described above, the chilled compartment container 4 a that can be drawn forward is accommodated in the chilled compartment 4 . Its structure is not limited, for example, as long as guide rails (not shown) extending in the front-rear direction are formed on the inner wall 1b forming the left and right side walls of the chilled compartment 4, the chilled compartment is slidably attached to the guide rails. The structure of the container 4a is sufficient. And the chilled compartment container 4a is attached so that it may separate from the partition part 4c, and the gap part 4a1 which communicates in the front-back direction is formed between the chilled compartment container 4a and the partition part 4c.

In addition, in the present embodiment, the cold air duct 17 is connected to the rear panel 1c disposed behind the chilled compartment 4, and the back panel 1c is opened so that the chilled compartment 4 communicates with the cold air duct 17.

As shown in FIG. 9 , one end of the cold air channel 17 connected to the rear panel 1 c arranged at the rear of the chilled compartment 4 extends downward, and the other end of the cold air channel 17 is connected to the cooler room 10 below the defrosting heater 15 . With this structure, the chilled compartment 4 communicates with the lower side of the cooler 12 of the cooler compartment 10 via the cold air duct 17 .

The cooler room 10 is provided with a cooling fan 11a and a freezing fan 11b, and is configured to draw cool air 100 from the cooler room 10 and supply it to each storage room of the refrigerator 1 . Therefore, when the ventilation fan 11 a for refrigeration and the ventilation fan 11 b for freezing are driven, the inside of the cooler compartment 10 is depressurized, and the cool air 100 in the chilled compartment 4 flows into the cooler compartment 10 through the cool air duct 17 . At this time, as shown in FIG. 8 , cold air 100 flows through gap 4a1 formed between chilled compartment container 4a and partition 4c, so that partition 4c can be cooled.

And by cooling the partition part 4c, the vegetable compartment 5 formed in the lower part can be cooled. In other words, vegetable compartment 5 is indirectly cooled by cold air 100 via partition 4c.

As shown in Figure 9, if the cold air channel 17 is arranged behind the cooler 12 and the defrosting heater 15, the cold air 100 flowing through the cold air channel 17 is cooled by the cooler 12, and the cold air 100 at a low temperature returns to the cooler chamber 10. . Therefore, the cooling load of the cooler 12 can be reduced, and the cooling efficiency can be improved.

In addition, since the cooler 12 does not interfere with the cold air duct 17 in the left-right direction, it is possible to install a large-sized cooler 12 having a wide width in the left-right direction.

In addition, for example, if the cold air duct 17 is piped to the left and right of the cooler 12, a temperature difference will be generated near the left and right ends of the cooler 12 and near the center, so that frost may concentrate on a specific part of the cooler 12. Case. The cooler 12 (evaporator) is formed of thin pipes through which the refrigerant flows. Therefore, if frost is concentrated at a specific location, the flow of the refrigerant may be hindered. On the other hand, if the cold air duct 17 is piped to the rear of the cooler 12, for example, the cold air duct 17 can be arranged on the entire rear surface of the cooler 12 (or a state similar to this), and the left and right ends can be reduced. The temperature difference between near the center and near the center. Therefore, it is possible to suppress the occurrence of concentrated frosting at a specific location, and it is possible to appropriately avoid a situation in which the flow of the refrigerant is hindered.
