  The fan cover 21 is formed to protrude forward from the fan base 20, and a front portion 21 a is formed at a position facing the blower fan 18. Cold air discharged from the blower fan 18 hits the back surface of the front portion 21a. Further, the front portion 21a is formed with a circular recess 21b facing the blower fan 18 in the center in the left-right direction (width direction). The concave portion 21b is formed so as to protrude rearward (so that the concave surface is directed forward) (see FIG. 3). By forming the recess 21b, the direction of the cool air discharged from the blower fan 18 can be smoothly changed toward the outside in the radial direction, and deterioration of the blowing efficiency can be suppressed.

  Moreover, the outer peripheral part 21c extended toward the fan base 20 from the outer peripheral part of the front part 21a is formed. The length of the outer peripheral portion 21c is such that when the fan cover 21 is attached to the fan base 20, a predetermined gap s20 (see FIG. 3) can be formed between the blower fan 18 and the recess 21b. The predetermined gap s20 is a distance at which cool air from the blower fan 18 can be discharged radially outward.

  The front portion 21a is formed so that a rectangular cutout portion 21d is opened upward above the recess 21b. In addition, a plurality of discharge ports 21e1, 21e2, 21f, 21g, 21g, 21h, 21i, and 21i through which cool air is discharged are formed in the front portion 21a. The discharge ports 21e1 and 21e2 are at the same height position. The discharge ports 21f, 21g, and 21g are at the same height position. The discharge ports 21h, 21i, and 21i are at the same height position.

  The cold air introducing member 22 includes a cold air distributing portion 22a that distributes cold air to the ice making chamber 40 (see FIG. 2) and the upper freezing chamber 50 (see FIG. 2). The cold air introduction member 22 includes a first cold air introduction path 22b that introduces cold air into the ice making chamber 40 (see FIG. 2), and a second cold air introduction path 22c that introduces cold air into the upper freezing chamber 50 (see FIG. 2). It is equipped with.

  The cold air distributor 22a has a rectangular cylindrical body 22a1 connected to the notch 21d, and a wind direction plate 22a2 for distributing the cold air to the ice making chamber 40 and the upper freezer compartment 50 at the upper end of the cylindrical body 22a1 ( Cold air distribution amount setting plate).

  The first cold air introduction path 22b has a cold air guide path 22b1 extending from the upper end of the cylindrical body 22a1 toward the left side (ice making chamber 40 side) and extending forward. The cold air guide path 22b1 is bifurcated at the tip, and has a wide air path 22b2 and an air path 22b3 narrower than the air path 22b2. Moreover, the front-end | tip of the air path 22b2 is set to the position higher than the front-end | tip of the air path 22b3. Further, an air passage 22b4 set lower than the tip of the air passage 22b2 is branched and formed in the air passage 22b2.

  Thus, by constituting the air passage 22b2, the cool air is discharged forward from the upper end of the ice making chamber 40. Further, the cool air is discharged from the position lower than the air passage 22b2 toward the ice making chamber 40 by the air passages 22b3 and 22b4.

  The second cold air introduction path 22c has a cold air guide path 22c1 extending along the front (partition member 16 (see FIG. 3)) from the upper end of the cylindrical body 22a1.

The cold air guide path 22c1 has a notch 22c2 formed on the surface facing the upper freezer compartment 50 (see FIG. 2). That is, the cold air guide path 22c1 is formed with a side wall 22c3 that blocks the flow of cool air at the tip of the cold air guide path 22c1 and a side wall 22c4 that blocks the flow of cold air toward the ice making chamber 40 (see FIG. 2). ing. Thus, since the side wall on the upper freezer compartment 50 side of the cold air guide path 22c1 is formed lower than the other side walls 22c3 and 22c4 by the notch 22c2, it is introduced (distributed) into the cold air guide path 22c1. Cold air is discharged toward the upper freezer compartment 50 (see FIG. 2) through the notch 22c2.

FIG. 5 is a top view showing a cold air introducing member that distributes cold air to the ice making chamber and the upper freezing chamber.
As shown in FIG. 5, the cold air introduction member 22 is formed such that the flow path width W1 of the first cold air introduction path 22b is wider than the flow path width W2 of the second cold air introduction path 22c. Thus, the amount of cold air introduced into the ice making chamber 40 can be increased by increasing the flow path width W1 of the first cold air introduction path 22b. In addition, the distribution amount of the cold air to the ice making chamber 40 and the upper freezing chamber 50 can be easily adjusted by changing the ratio of the channel widths W1 and W2. Moreover, the distribution amount of the cold air to the ice making chamber 40 and the upper freezing chamber 50 can be adjusted by changing the shape of the wind direction plate 22a2.

  The cool air distributor 22a is formed such that the wind direction plate 22a2 covers substantially half of the opening of the cylindrical body 22a1 in a top view (plan view). The wind direction plate 22a2 is formed by bending the plate materials 22a3 and 22a4. The plate member 22a3 is disposed to be inclined so as to rise toward the first cold air introduction path 22b. The plate member 22a4 is disposed so as to be inclined toward the front side. Cold air is guided toward the first cold air introduction path 22b by the plate material 22a3, and cold air is guided toward the second cold air introduction path 22c by the plate material 22a4.

FIG. 6 is a perspective view showing a state after the cold air introduction member is assembled.
As shown in FIG. 6, the fan cover 21 is attached to the fan base 20 so as to cover the blower fan 18. At this time, the edge (not shown) of the fan cover 21 is sandwiched between the ribs 20e1, 20e2, 20e3, 20e4 (see FIG. 4) and the claw portions 20f1, 20f2, 20f3, 20f4 (see FIG. 4). 20 is locked. Although not shown, the fan cover 21 has a fan base through a sponge-like packing except for the portions where the ribs 20e1, 20e2, 20e3, 20e4 and the claw portions 20f1, 20f2, 20f3, 20f4 are arranged. 20 is fixed. Moreover, the outer peripheral edge part of the back surface side of the fan base 20 is fixed to the inner box 11 (refer FIG. 3) through the same packing.

  Then, the cool air introducing member 22 is fitted into a notch 21d formed in the upper part of the fan cover 21, and the state shown in FIG. 6 is reached. Moreover, the upper end of the cold air introducing member 22 is attached so as to contact the lower surface of the heat insulating partition member 17 (see FIG. 3).

7A and 7B show the cold air supply member, where FIG. 7A is a front view, FIG. 7B is a cross-sectional view taken along the line BB in FIG. 7A, and FIG.
As shown in FIG. 7A, the fan cover 21 has a smaller area in plan view than the fan base 20. The lower end edge portion 21m of the fan cover 21 is fixed to the fan base 20 by the claw portions 20f3 and 20f4. The left edge portion 21n of the fan cover 21 is fixed to the fan base 20 by claw portions 20f1 and 20f2.

  The upper edge of the front portion 21a of the fan cover 21 is not symmetrical with respect to the recess 21b. The upper edge 21p is formed on the right side of the recess 21b, and the upper edge 21q is formed on the left side. Yes. The upper edge portion 21p is formed so as to extend downward while being curved after inclining so as to descend rightward from above the recess 21b. The upper end edge portion 21q is formed to have a mountain shape and a convex shape upward at substantially the same height as the center of the concave portion 21b. Further, the upper edge 21q is formed in a mountain shape so as to cover the upper side of the left discharge port 21e1. The fan cover 21 is formed so as to extend from the right end of the upper end edge portion 21q (the end portion on the concave portion 21b side) toward the upper cylindrical body 22a1.

  The cool air distribution unit 22 a is located on the projection above the blower fan 18 in the vertical direction. The blower fan 18 rotates in the clockwise direction W10 when viewed from the front. In this case, the positional relationship between the blower fan 18 and the cool air distributor 22a is such that the cool air distributor 22a is disposed on the left side with respect to the blower fan 18. Thereby, the cold air from the blower fan 18 is smoothly introduced toward the cold air distribution part 22a, and the air blowing efficiency is improved.

  Further, the cool air from the blower fan 18 hits the outer peripheral portion 21c including the upper end edge portion 21q, whereby the cool air is discharged from the discharge port 21e1. Further, the cool air discharged later than the cool air discharged toward the cool air distributing portion 22a hits the outer peripheral portion 21c including the upper end edge portion 21p, and is discharged from the discharge port 21e2. The cool air that has not been discharged from the discharge ports 21e1, 21e2 is appropriately discharged from the discharge ports 21f, 21g, 21g, 21h, 21i, 21i below the discharge ports 21e1, 21e2.

The cool air discharged from the discharge ports 21f, 21g, and 21g is discharged to the middle storage container 62 (see FIG. 2). The cold air protruding from the discharge ports 21h, 21i, 21i is discharged to the lower storage container 61 (see FIG. 2).

  As shown in FIG. 7B, the fan cover 21 is attached to the fan base 20 via claw portions 20f3, 20f4 and the like. By attaching the fan cover 21 to the fan base 20, a space is formed between the fan cover 21 and the fan base 20. By the way, since it is assumed that frost is generated in this space and the frost is melted to generate water, it is necessary to discharge such water.

  Therefore, in the present embodiment, the water drain holes 21 s and 21 s are formed in the fan cover 21. The drain hole 21s is formed at a position facing the claw portions 20f3 and 20f4. FIG. 7B shows a state in which the fan cover 21 is locked to the fan base 20 by the claw portions 20f3 and 20f4 as viewed from the inside of the fan cover 21. FIG. Thus, the drain holes (notches) 21 s and 21 s are formed on the bottom surface 21 t of the edge of the fan cover 21. The drain holes 21s are configured to penetrate vertically in both the left and right sides of the base ends of the claw portions 20f3 and 20f4 in a state where the fan cover 21 is attached to the fan base 20.

  As shown in FIG. 7C, the front surface portion 21a of the fan cover 21 has an inclined surface portion 21a1 inclined in a direction approaching the fan base 20 below the surface on which the concave portion 21b (see FIG. 7A) is formed. Is formed. Thereby, the distance between the fan cover 21 and the fan base 20 is formed so as to become shorter downward.

  Further, the bottom surface 21t of the fan cover 21 is notched so as not to contact the fan base 20 at a position facing the claw portion 20f4, thereby forming a drain hole 21s. Further, the bottom surface 21t is formed with a step portion 21r into which the hook-shaped portion of the claw portion 20f4 is fitted. With the shape shown in FIG. 7C, the drain water generated in the fan cover 21 can be discharged to the outside of the fan cover 21 through the drain hole 21s.

  Further, on the surface of the fan base 20, a flange 20h (see FIG. 7A) for guiding the water discharged from the drain hole 21s is formed below the drain hole 21s. The flange portion 20h is located between the water drain hole 21s and the intake port 20g. In addition, the flange portion 20h is formed of a protruding member from the surface of the fan base 20, and is substantially Y-shaped when viewed from the front. Moreover, the center of the width direction (left-right direction) of the collar part 20h is extended to the upper end of the intake port 20g. The fan base 20 is formed with a through hole 20i that penetrates the fan base 20 at the lower end of the flange 20h.

  Thereby, the water discharged from the water drain hole 21s falls along the surface of the fan base 20, and is received by the flange portion 20h. The water received by the flange 20h gathers in the center along the inclination of the flange 20h, and is discharged to the back side of the fan base 20 through the through hole 20i. The water discharged to the back side of the fan base 20 is once dropped into the trough 9c (see FIG. 3) in the same manner as the drain water generated in the cooler 9, and then passes through the drain hole 9d (see FIG. 3). Then, it is stored in an evaporating dish (not shown) provided in the upper part of the compressor (not shown).

  The flow of the cold air will be described. The cold air generated by the cooler 9 (see FIG. 3) is sucked from the back by the blower fan 18 and discharged to the front portion 21a (front) of the fan cover 21. Then, the cold air passes through the fan cover 21 and is introduced into the cold air distribution unit 22a. The cold air introduced into the cold air distribution unit 22a is distributed to the first cold air introduction path 22b and the second cold air introduction path 22c. The cold air introduced into the first cold air introduction path 22 b is introduced into the ice making chamber 40 from the rear of the ice making chamber 40.

  As shown in FIG. 8, the cold air introduced into the second cold air introduction path 22c is discharged from the side surface of the upper freezer compartment 50 through the notch 22c2. A part of the inner box 11 </ b> A (11) is exposed at the back of the upper freezer compartment 50. Thereby, since it is not necessary to provide an air passage (duct) for discharging cool air at the rear part of the upper freezer compartment 50, the internal volume of the upper freezer compartment 50 can be expanded.

  The cold air that has passed through the ice making chamber 40 and the upper freezing chamber 50 passes through the lower freezing chamber 60 (see FIG. 3), and is sucked into the fan base 20 from the intake port 20g (see FIGS. 3 and 7) ( And is cooled again by the cooler 9 (see FIG. 3).

  As described above, the refrigerator 100 of the present embodiment includes the ice making room 40 (first freezing room) and the upper freezing room 50 (second freezing room) arranged side by side as the freezing room, and the ice making room 40. And a partition member 16 disposed between the upper freezer compartment 50 and the upper freezer compartment 50. The cold air supply member R (cold air supply passage) includes a first cold air introduction passage 22b for introducing cold air into the ice making chamber 40, a second cold air introduction passage 22c for introducing cold air into the upper freezing chamber 50, and a first cold air introduction passage 22b. And a cold air distribution part 22a for distributing cold air to the second cold air introduction path 22c. The cold air distribution part 22 a and the second cold air introduction path 22 c (at least one of the first cold air introduction path and the second cold air introduction path) are located on the projection in the front-rear direction of the partition member 16. As a result, the inner boxes 11B and 11 (see FIG. 2) can be exposed on the back wall of the ice making chamber 40, and the inner box 11A (11) can be exposed on the back wall of the upper freezing chamber 50. . Thus, by storing the cold air distribution part 22a and the second cold air introduction path 22c in the front-rear direction after the partition member 16, the internal volume of the upper freezer compartment 50 can be increased, and the food storage space can be increased. It becomes possible to expand. The partition member 16 always requires rail members 41b and 51a for sliding the storage container of the ice making chamber 40 and the storage container of the upper freezing chamber 50, and a dead space is generated. By arranging the cold air distribution section 22a and the second cold air introduction path 22c as cold air passages in the dead space, the space can be effectively utilized.

  Moreover, in this embodiment, the cold air distribution part 22a is located on the projection above the vertical direction of the ventilation fan 18 (refer Fig.7 (a)). Thereby, since the cool air from the blower fan 18 can be smoothly introduced into the cool air distributor 22a, the air blowing efficiency can be improved.

  Moreover, in this embodiment, the fan cover 21 which accommodates the ventilation fan 18 is provided, and the fan cover 21 has the drain hole 21s which discharges the water produced | generated from the refrigerating cycle F (refer FIG.7 (b), (c)). ). Thereby, even when frost is generated in the fan cover 21 constituting the cold air supply member R and the frost is melted and water is generated, the water can be prevented from collecting in the fan cover 21. Accordingly, it is possible to prevent the discharge ports 21h, 21i and the like from being blocked by the water being frozen, and the discharge of the cold air from being inhibited.

  In the present embodiment, the drain hole 21s is located behind the rear end 61e of the lower storage container 61 (case) that is stored in the lower freezer compartment 60 (see FIG. 3). As a result, even if the water droplets discharged from the water drain hole 21s solidify and become icicles, they can be prevented from falling into the lower storage container 61. Therefore, the food in the lower storage container 61 can be prevented from being damaged.

FIG. 9 is a configuration diagram showing a refrigerator provided with a cooler in the refrigerator compartment and the freezer compartment.
As shown in FIG. 9, the refrigerator 100 includes, as a refrigeration cycle, a cooler 31 (refrigerator cooler) that cools the refrigerator compartment 30 and a freezer compartment (the ice making chamber 40, the upper freezer compartment 50, and the lower freezer compartment 60). And a cooler 9 for cooling. That is, the refrigerator compartment 30 is cooled only by the cooler 31, and the freezer compartment is cooled only by the cooler 9.

  The cooler 31 is formed smaller than the cooler 9 and is provided on the back surface of the lower end of the refrigerator compartment 30. Further, the cooler 31 is arranged on the right side of the center of the refrigerator 100 in the width direction. Thus, by separating the cooler 31 for the refrigerating chamber 30 and the cooler 9 for the freezer compartment, the cooler 9 can be reduced in size (for example, 7 stages → 5 stages). Thereby, the volume of the forward protrusion on the back surface of the freezer compartment can be reduced, and the volume of the freezer compartment can be increased.

  A blower fan 32 is provided above the cooler 31. The cooler 31 and the blower fan 32 are accommodated in a duct 33. Thus, the cold air generated by the cooler 31 is carried upward by the blower fan 32 and discharged into the refrigerator compartment 30 from a discharge port (not shown) formed in the duct 33.

  The refrigerator 100 includes a heat insulating partition member 17 that partitions the refrigerator compartment 30 and the freezer compartment in an adiabatic manner. The heat insulating partition member 17 is integrally formed with a flange portion 17a for melting and treating frost attached to the cooler 31. The flange portion 17a is formed with an inclined surface 17a1 that is inclined linearly from the position of the refrigerant distribution portion 22a toward the right side (cooler 31 side). The inclined surface 17a1 extends to the vicinity of the right side plate 1b. Note that the vicinity means, for example, a position that overlaps the right end of the cooler 31 in the vertical direction. A drain pipe 17b is connected to the lower end of the inclined surface 17a1. The drain pipe 17b extends to the machine room Q (see FIG. 1). Thus, by making the drain pipe 17b the end of the inner box 11, the inclination of the inclined surface 17a1 can be made gentle, and the flange portion 17a to the freezing room (the ice making room 40 and the upper freezing room 50) can be made. The downward protrusion can be suppressed. Therefore, it can suppress that the internal volume of a freezer compartment is reduced significantly. Further, by disposing the flange portion 17a on the right side, it is possible to secure a large volume on the inner side of the ice making chamber 40.

  Further, as shown in FIG. 9, the fan cover 21 is provided with a duct 21 u that communicates with the vegetable compartment 70. The duct 21u extends into the vegetable compartment 70 through a heat insulating partition that partitions the lower freezing compartment 60 and the vegetable compartment 70 in an adiabatic manner. A damper 21x is provided at the tip (lower end) of the duct 21u. When the damper 21x is opened, cold air is supplied into the vegetable compartment 70, and when the damper 21x is closed, supply of cold air to the vegetable compartment 70 is shut off. The cold air supplied to the vegetable compartment 70 is configured to return to the cooler 9 via an intake port and piping (not shown).

  Thus, in the present embodiment, the refrigeration cycle F includes the cooler 31 that cools the refrigerator compartment 30 and the cooler 9 that cools the refrigerator compartment. The refrigerator compartment 30 and the freezer compartment are partitioned by a heat insulating partition member 17. The heat insulating partition member 17 is provided with a flange portion 17a through which drainage from the cooler 31 flows. For example, in the conventional structure in which cool air is discharged from the rear of the upper freezer compartment, when the coolers are separately provided for the freezer compartment and the freezer compartment, the structure of the flange portion 17a projects into the freezer compartment, The discharge port protrudes further forward and the structure of the air path is further complicated. However, as in the present embodiment, the cold air distribution portion 22a and the second cold air introduction path 22c are provided on the projection in the front-rear direction of the partition member 16 (see FIG. 8), and the cold air is discharged from the side surface of the upper freezer compartment 50. This is particularly effective for those provided with the flange portion 17a.

  While the present embodiment has been described with reference to the drawings, the present embodiment is not limited to the above contents. Therefore, various modifications are included in the present invention. That is, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to one having all the configurations described.

  For example, in the present embodiment, the cool air introduced into the ice making chamber 40 is set to be the cool air introduced into the upper freezing chamber 50 from the side, but conversely, the cool air introduced into the ice making chamber 40 is From the side, the cool air introduced into the upper freezer compartment 50 may be used later. Further, in one of the ice making chamber 40 and the upper freezing chamber 50, the cold air is projected from the side, but cold air may be discharged from both the ice making chamber 40 and the upper freezing chamber 50.

  In the present embodiment, the case where the cooler 9 that cools the freezer compartment and the cooler 31 that cools the refrigerator compartment 30 are divided and described as an example. The cooler which cools the refrigerator compartment 30 and the freezer compartment may be provided in the back surface.
