And as shown to (a) of FIG. 6, (b), it is preferable that the attachment angle (theta) 1 of the ventilation fan 11a for refrigeration is smaller than the attachment angle (theta) 2 of the ventilation fan 11b for freezing.
The attachment angle here is an angle formed by the discharge direction of the cool air 100 and the vertical direction, and the cool air 100 is discharged upward as the attachment angle decreases.
That is, it is preferable that the refrigeration blower fan 11a is attached at an attachment angle such that the cool air 100 is discharged upward from the refrigeration blower fan 11b. The refrigeration blower fan 11a having a smaller attachment angle θ1 than the attachment angle θ2 of the refrigeration blower fan 11b discharges the cool air 100 upward from the refrigeration blower fan 11b.
Therefore, the refrigeration blower fan 11a with a small mounting angle can blow the cold air 100 to the refrigeration temperature zone cool air flow path 18 extending upward.
In addition, the refrigeration blower fan 11b having a large attachment angle can blow the cold air 100 to the refrigeration temperature zone cool air flow path 19 extending downward.

Moreover, as shown to (a) of FIG. 4, FIG. 5, the ventilation fan 11a for refrigerating and the ventilation fan 11b for freezing of a present Example are located in right and left, rather than the partition 5a between the vegetable compartment 5 and the freezing compartment 6. Arranged above. Furthermore, it is preferable that the refrigeration blower fan 11a is arranged at a position above the refrigeration blower fan 11b.
That is, the refrigeration blower fan is such that the uppermost part of the flow of the cold air 100 discharged from the refrigeration blower fan 11a is positioned above the uppermost part of the flow of the cold air 100 discharged from the refrigeration blower fan 11b. It is preferable that 11a and the ventilation fan 11b for freezing are arrange | positioned.

  Since the refrigeration blower fan 11a is a fan that blows the cool air 100 supplied to the refrigeration chamber 3 and the chilled chamber 4 disposed above the partition wall 5a, the refrigeration blower fan 11a is disposed at an upper position. As a result, the flow path length of the cold air 100 is shortened, and the efficiency of supplying the cold air 100 to the refrigerating chamber 3 and the chilled chamber 4 can be improved. And the refrigerator compartment 3 and the chilled room 4 can be cooled efficiently.

  When both the refrigeration blower fan 11a and the refrigeration blower fan 11b have a rectangular outer frame facing the discharge side So, the refrigeration blower fan 11a and the refrigeration blower fan 11b are both forward and backward. It is preferable that the refrigeration blower fan 11a and the refrigeration blower fan 11b have different inclination angles with respect to the left-right direction.

  In the present embodiment, the inclination angle of the refrigeration blower fan 11a and the freezing blower fan 11b is an angle at which the outer frame of the refrigeration blower fan 11a and the freezing blower fan 11b is inclined with respect to the left-right direction. And

For example, as shown in FIG. 7, the refrigeration blower fan 11a has an angle θ3 formed by one side of the upper (or lower) side of the outer frame facing the front side of the refrigeration blower fan 11a having a rectangular outer frame. The inclination angle of Similarly, an angle θ4 formed by one side of the upper (or lower) side of the outer frame facing the front of the refrigeration blower fan 11b having a rectangular outer frame is defined as an inclination angle of the refrigeration blower fan 11b.
In this embodiment, the inclination angle θ3 of the refrigeration blower fan 11a is different from the inclination angle θ4 of the refrigeration blower fan 11b. For example, as shown in FIG. 7, the angle θ4 (inclination angle of the refrigeration blower fan 11b) is larger than the angle θ3 (inclination angle of the refrigeration blower fan 11a) (angle θ4> angle θ3).

When the inclination angle θ3 of the refrigeration blower fan 11a and the inclination angle θ4 of the refrigeration blower fan 11b are equal (angle θ3 = angle θ4), the vibration of the refrigeration blower fan 11a and the vibration of the refrigeration blower fan 11b are the same. In some cases, the transmission characteristics transmit to the fixed plate 10b to resonate with each other, and the vibration of the fixed plate 10b increases. In this case, problems such as an increase in noise in the refrigerator 1 (see FIG. 1) may occur.
As the inclination angle θ3 of the refrigeration blower fan 11a defined as shown in FIG. 7 and the inclination angle θ4 of the refrigeration blower fan 11b are different, the vibration of the refrigeration blower fan 11a and the vibration of the refrigeration blower fan 11b are The transmission characteristics to the fixed plate 10b can be changed, and the resonance of vibrations of the refrigeration blower fan 11a and the refrigeration blower fan 11b can be suppressed. As a result, the vibration of the fixed plate 10b can be suppressed, and the noise of the refrigerator 1 (see FIG. 1) can be reduced.

  Further, the refrigeration blower fan 11a and the refrigeration blower fan 11b are attached with inclination angles θ3 and θ4, respectively, thereby avoiding the interference in the left and right direction between the refrigeration blower fan 11a and the refrigeration blower fan 11b. A large refrigeration blower fan 11a and a refrigeration blower fan 11b can be attached.

The circulating cold air 100 is supplied from the refrigeration outlet 18a, and the chilled chamber 4 is cooled.

The chilled chamber 4 houses a chilled chamber container 4a that can be drawn forward as described above. The structure is not limited, but, for example, 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 chamber 4, and the chilled chamber container is formed on the guide rails. What is necessary is just to set it as the structure attached 4a so that a slide movement is possible. The chilled chamber container 4a is attached separately from the partition portion 4c, and a gap portion 4a1 communicating in the front-rear direction is formed between the chilled chamber container 4a and the partition portion 4c.
Furthermore, in this embodiment, the cold air duct 17 is connected to the back plate 1c disposed behind the chilled chamber 4, and the back plate 1c is opened so that the chilled chamber 4 and the cold air duct 17 communicate with each other.

As shown in FIG. 9, the cold air duct 17 having one end connected to the back plate 1 c provided behind the chilled chamber 4 extends downward, and the other end is connected to the cooler chamber 10 below the defrost heater 15. . With this configuration, the chilled chamber 4 communicates with the lower portion of the cooler 12 in the cooler chamber 10 via the cold air duct 17.
The cooler room 10 is provided with a refrigeration blower fan 11 a and a refrigeration blower fan 11 b. The cooler room 10 sucks cold air 100 from the cooler room 10 and supplies it to each storage room of the refrigerator 1. Therefore, when the refrigeration blower fan 11 a and the freezing blower fan 11 b are driven, the inside of the cooler chamber 10 is depressurized, and the cold air 100 in the chilled chamber 4 flows to the cooler chamber 10 through the cold air duct 17. At this time, as shown in FIG. 8, since the cool air 100 flows through the gap 4a1 formed between the chilled chamber container 4a and the partition 4c, the partition 4c is cooled.

And the vegetable compartment 5 formed below is cooled by cooling the partition part 4c. That is, the vegetable compartment 5 is indirectly cooled by the cold air 100 via the partition part 4c. There are many cases where vegetables are stored in the vegetable room 5, and when it is excessively cooled, problems such as “vegetable frostbite” may occur. Since the vegetable compartment 5 of a present Example is indirectly cooled via the partition part 4c, the excessive cooling of the vegetable compartment 5 is suppressed.
For this reason, it is preferable that the partition part 4c is formed with a member with high heat transfer efficiency.

  The chilled chamber container 4a is cooled from below when the cool air 100 flows through the gap 4a1 formed below the chilled chamber container 4a. Therefore, the chilled chamber container 4a is efficiently cooled, and the stored items in the chilled chamber container 4a can be efficiently cooled.

In addition, it is preferable that the cold air | gas duct 17 is a structure formed with the pipe line piped so that it may pass through the back of the cooler 12 and the defrost heater 15. FIG. 9, the inner wall 1b (see FIG. 3) is not shown, and the lower end of the cool air duct 17 may be connected to the inner wall 1b behind the cooler chamber 10.
Further, FIG. 9 shows a configuration in which two cold air ducts 17 are provided in parallel in the left-right direction. However, a configuration in which one cold air duct 17 is provided may be provided, or three or more cold air ducts 17 may be provided. The structure provided may be sufficient.

As shown in FIG. 9, when the cool air duct 17 is disposed behind the cooler 12 and the defrosting heater 15, the cool air 100 flowing through the cool air duct 17 is cooled by the cooler 12, and the cooler room 10 has low temperature cool air. 100 will return. Therefore, the cooling load of the cooler 12 can be reduced and the cooling efficiency can be improved.
Moreover, since the cooler 12 and the cold air duct 17 do not interfere in the left-right direction, a large cooler 12 having a wide width in the left-right direction can be installed.

  Further, for example, when the cold air duct 17 is connected to the left and right of the cooler 12, a temperature difference occurs between the vicinity of the left and right ends of the cooler 12 and the vicinity of the center, and therefore, it concentrates on a specific part of the cooler 12. May form frost. Since the cooler 12 (evaporator) is formed by a thin pipe line through which the refrigerant flows, if the frost is concentrated on a specific part, the refrigerant flow may be hindered. On the other hand, when the cold air duct 17 is piped behind the cooler 12, for example, the cold air duct 17 can be piped over the entire rear face of the cooler 12 (or close to it). Thus, the temperature difference between the left and right end portions and the central portion can be reduced. Therefore, generation | occurrence | production of the phenomenon which concentrates on a specific site | part and forms frost can be suppressed, and it can avoid suitably that the distribution | circulation of a refrigerant | coolant is prevented.

  Also, as shown in FIG. 10, a plurality of groove portions 5a1 (two are illustrated in FIG. 10) extend forward from the through hole 5a2 on the lower surface of the partition wall 5a, and the lower portion of the groove portion 5a1 is a cover member. It is closed at 5a3. Since the groove portion 5a1 configured in this manner communicates with the through hole 5a2, the groove portion 5a1 communicates with the cooler chamber 10 (see FIG. 8). As shown in FIG. 11, the groove portion 5a1 closed by the cover member 5a3 A pipe line (cold air pipe line 60) through which the cold air 100 flows and circulates is formed. In other words, the cold air pipe 60 is a pipe that extends in the front-rear direction of the partition wall 5 a and has a rear end portion that communicates with the cooler chamber 10. Function.

Further, in the cover member 5a3, for example, through holes 5a4 are appropriately formed in the front, rear, and intermediate portions thereof, and the cold air 100 flowing through the cold air duct 60 (groove 5a1) is blown downward from the through holes 5a4. Is preferred.
The method for fixing the cover member 5a3 to the partition wall 5a is not limited.

A freezing container 6a is accommodated.

  The upper freezing container 6a is formed in a box shape having an upper opening, and is arranged so that the upper end faces the lower surface of the partition wall 5a. Therefore, the opened upper end of the upper freezing container 6a faces the cover member 5a3 that closes the lower portion of the groove 5a1. With this configuration, the cold air 100 that flows through the cold air duct 60 (groove 5a1) and blows out from the through hole 5a4 is supplied to the inside of the upper freezing container 6a, and the stored product in the upper freezing container 6a is cooled.

  Moreover, as shown in FIG. 11, it is good also as a structure which the lower stage freezing container 6b protrudes back rather than the upper stage freezing container 6a. With this configuration, the rear side of the lower freezing container 6b opens upward, and the cold air 100 supplied to the freezing chamber 6 from the rear side is supplied to the lower freezing container 6b from the opening formed in the projecting portion, and the lower freezing container 6b. The 6b stock is cooled.

Although not shown, at least a part of the front surface of the upper freezing container 6a may be retracted to the position of the through hole 5a4 formed in the forefront of the cover member 5a3. For example, the structure where the front surface of the upper stage freezing container 6a is curving back so that it may become concave shape to the position of the said through-hole 5a4 may be sufficient.
According to this configuration, a gap is formed at the upper end of the front surface of the lower freezing container 6b, and the cool air 100 blown out from the through hole 5a4 formed in the forefront of the cover member 5a3 flows into the lower freezing container 6b from this gap. Therefore, the cool air 100 is efficiently supplied to the inside of the lower freezing container 6b, and the stored items in the lower freezing container 6b are effectively cooled.

Further, in order to efficiently feed the cold air 100 into the cold air duct 60 (groove 5a1) of the partition wall 5a, as shown in FIG. 4 and FIG. 6 (b), for refrigeration disposed below the refrigeration blower fan 11a.

Further, as shown in FIG. 11, when the cool air 100 flows through the cool air duct 60 formed in the partition wall 5a, the partition wall 5a is cooled by the cool air 100 flowing through the cool air duct 60. And the cooled partition 5a cools the vegetable compartment 5 arrange | positioned upwards. Therefore, the vegetable compartment 5 is indirectly cooled by the cold air 100 via the partition wall 5a, and the efficiency of cooling the vegetable compartment 5 is improved, and the excessive cooling of the vegetable compartment 5 is suppressed by the indirect cooling. Is done.
Furthermore, the vegetable compartment 5 is cooled from both the upper and lower directions by the upper partition 4c (see FIG. 8) and the lower partition 5a.
