As a result, the direction of the cool air changes from the direction D1 to D2, and the cool air flows toward the central portion 26e of the refrigerating chamber 26. As a result, the direction in which the cool air flows can be changed by the first guide surface 70a of the first guide member 70.

The second guide member 72 is fixed to the right side surface 26c of the refrigerator compartment 26. The second guide member 72 is arranged closer to the front surface 26a side of the refrigerating compartment 26 than the first guide member 70. The second guide member 72 has a second guide surface 72a located on the suction port 64 side (that is, the duct member 50 side). Therefore, as shown in FIG. 2, when the cool air which is guided by the first guide member 70 and flows in the direction D2 flows to the second guide member 72, the cool air moves along the second guide surface 72a of the second guide member 72. Flowing. As a result, the direction of the cool air changes from the direction D2 to D3, and the cool air flows toward the rear surface 26d side of the refrigerating chamber 26. As a result, the second guide surface 72a of the second guide member 72 can circulate the cool air in the refrigerating chamber 26.

Further, a suction port 64 is formed between the duct plate 52 and the surface of the housing 12 on the refrigerating chamber 26 side. The suction port 64 is opened to suck cold air from the refrigerating chamber 26 toward the second flow path 58. Therefore, as shown in FIG. 2, when the cool air which is guided by the second guide member 72 and flows in the direction D3 flows to the rear surface 26d of the refrigerating chamber 26, the cool air is sucked into the suction port 64. As a result, the cool air can be efficiently sucked into the suction port 64.

The first guide member 70 is fixed to the left side surface 26b of the refrigerator compartment 26. Therefore, it is possible to secure a space for storing food in the refrigerating compartment 26.

Is equal to the first distance L1 from the surface on the first flow path 56 side. The second louver 176 guides the cool air flowing through the first flow path 56 to the second opening 166.

As shown in FIG. 5, the third louver 178 is arranged along the edge of the third opening 168 on the central position side of the duct plate 52. Although not shown, the third louver 178 extends from the upstream edge of the third opening 168 located most upstream of the first flow path 56 to the downstream edge of the third opening 168 located most downstream. It is extended. The base portion 178a of the third louver 178 is fixed to the surface of the duct plate 52 on the first flow path 56 side. The third louver 178 has the same shape as the first louver 174. Therefore, as shown in FIG. 4, the third distance L3 between the tip portion 178b of the third louver 178 and the surface of the duct plate 52 on the first flow path 56 side is equal to the tip portion 174b of the first louver 174. Equal to the first distance L1 between. The third louver 178 guides the cool air flowing through the first flow path 56 to the third opening 168.

As shown in FIG. 5, the fourth louver 180 is arranged along the edge of the fourth opening 170 on the central position side of the duct plate 52. Although illustration is omitted, the fourth louver 180 includes a downstream edge of the fourth opening 170 located on the most downstream side from an upstream edge of the fourth opening 170 located on the most upstream side of the first flow path 56. Has been extended to. The base 180a of the fourth louver 180 is fixed to the surface of the duct plate 52 on the first flow path 56 side. The fourth louver 180 has the same shape as the second louver 176. Therefore, as shown in FIG. 4, the fourth distance L4 between the front end portion 180b of the fourth louver 180 and the first flow path 56 side of the duct plate 52 is equal to the front end portion 178b of the third louver 178 and the duct plate. Equal to the third distance L3 between 52 and 52. The fourth louver 180 guides the cool air flowing through the first flow path 56 to the fourth opening 170.

Next, with reference to FIG. 5, the flow of cold air in the refrigerator compartment 26 of the refrigerator 100 will be described. Below, the flow of the cool air which flows through the refrigerating room 26 in the closed state in which the door 36 closes the front opening 26a of the refrigerating room 26 will be described. First, the flow of cold air blown from the first opening 164 and the third opening 168 into the refrigerating chamber 26 will be described. Since the characteristics of the cold air blown out from the first opening 164 are the same as the characteristics of the cold air blown out from the third opening 168, the cold air blown out from the first opening 164 will be described below. The cool air flowing through the first flow passage 56 passes between the tip portion 174b of the first louver 174 and the surface of the duct plate 52 on the first flow passage 56 side, and flows along the first louver 174. After that, the cool air blows out from the first opening 164 into the refrigerating chamber 26 in the direction F1 shown in FIG. The direction F1 is the direction of cold air flowing from the left side of the center position of the width of the partition body 38 in the left-right direction toward the right door 36b on the right side of the partition body 38. The direction F1 is inclined with respect to the front-back direction by a first angle A1. The cool air blows from the first opening 164 toward the refrigerating chamber 26 so as to avoid the partition 38.

Next, the flow of cold air blown into the refrigerating chamber 26 from the second opening 166 and the fourth opening 170 will be described. Since the characteristics of the cool air blown out from the second opening 166 are the same as the characteristics of the cool air blown out from the fourth opening 170, the cool air blown out from the second opening 166 will be described below. The cool air flowing through the first flow passage 56 passes between the tip portion 176b of the second louver 176 and the surface of the duct plate 52 on the first flow passage 56 side, and flows along the second louver 176. Then, the cool air is blown into the refrigerating chamber 26 from the second opening 166 in the direction of the direction F2 shown in FIG. The direction F2 is the direction of cold air flowing from the right side of the center position of the width of the partition body 38 in the left-right direction toward the right door 36b on the right side of the partition body 38. The direction F2 is inclined with respect to the front-rear direction by the second angle A2. The second angle A2 is smaller than the first angle A1. The cool air blows from the second opening 166 toward the refrigerating chamber 26 so as to avoid the partition 38.

Further, as described above, the opening area of the first opening 164 is larger than the opening area of the second opening 166. Therefore, the first flow rate of the cool air blown out from the first opening 164 is larger than the second flow rate of the cool air blown out from the second opening 166. As a result, the cold air blown out from the second opening 166 does not flow across the cool air blown out from the first opening 164. Thereby, the cold air blown out from the second opening 166 does not flow toward the left door 36a but flows toward the right door 36b. Cool air flows to a position avoiding the partition 38.

(effect)
As described above, in the refrigerator 100 of the second embodiment, when the refrigerating room 26 is viewed from the front, the plurality of first openings 164 are arranged closer to the left door 36a than the center position of the width of the partition 38 in the left-right direction. The plurality of second openings 166 are arranged closer to the right door 36b than the center position of the width of the partition body 38 in the left-right direction. The first flow rate of the cool air blown out from the first opening 164 is larger than the second flow rate of the cool air blown out from the second opening 166. Therefore, the flow rate of the cool air blown out from each of the openings (the first opening 164 and the second opening 166) is smaller than that in the case where the blowing port 162 has one opening. As a result, for example, even if the direction of the cool air changes due to the food placed on the placing shelf fixed to the duct plate 52 and the cool air hits the partition body 38, the blowout port 162 has one opening. Compared with the case, it is possible to suppress the temperature of the partition body 38 from decreasing. Thereby, it is possible to suppress the occurrence of dew condensation on the partition body 38.

The opening area of the first opening 164 is larger than the opening area of the second opening 166. Therefore, the first flow rate of the cool air blown from the first opening 164 to the refrigerating chamber 26 can be made larger than the second flow rate of the cool air blown to the refrigerating chamber 26 from the second opening 166.

Further, the first opening 164 is opened so that cold air is blown into the refrigerating chamber 26. The cool air blown out from the first opening 164 flows from the left side of the center position of the width of the partition body 38 in the left-right direction toward the right door 36b on the right side of the partition body 38. The first flow rate of the cool air blown from the first opening 164 is larger than the second flow rate of the cool air blown from the second opening 166. Therefore, the cool air blown out from the second opening 166 does not flow toward the left door 36a due to the cool air blown out from the first opening 164. Therefore, it is possible to prevent the cool air blown from the second opening 166 from hitting the partition body 38.

The inclination angle of the first louver 174 is larger than the inclination angle of the second louver 176. Therefore, the first angle A1 of the cool air blown out from the first opening 164 is smaller than the second angle A2 of the cool air blown out from the second opening 166. As a result, the direction of the cool air blown from the first opening 164 and the second opening 166 can be adjusted by the inclination angle of the first louver 174 and the second louver 176.

The first opening 164 and the third opening 168 are examples of the “first opening”, and the second openings 166 and the fourth opening 170 are examples of the “second opening”.

(Third embodiment)
A third embodiment will be described with reference to FIG. In the third embodiment, the points different from the second embodiment will be described, and the same points as the second embodiment will be designated by the same reference numerals and description thereof will be omitted. In the third embodiment, the vertical width and the horizontal width W1 of the first opening 164 are equal to the vertical width and the horizontal width W2 of the second opening 166, respectively. Further, the vertical width and the horizontal width W3 of the third opening 168 are equal to the vertical width and the horizontal width W4 of the fourth opening 170, respectively. That is, the shape of the first opening 164, the shape of the second opening 166, the shape of the third opening 168, and the shape of the fourth opening 170 are the same. As a result, when the refrigerating chamber 26 is viewed from the front, the first opening 164, the second opening 166, the third opening 168, and the fourth opening 170 can have the same appearance.

The first distance L1 between the tip 174b of the first louver 174 and the duct plate 52 is longer than the second distance L2 between the tip 176b of the second louver 176 and the duct plate 52. Therefore, the flow rate of the cool air passing between the tip portion 174b of the first louver 174 and the duct plate 52 is larger than the flow rate of the cool air passing between the tip portion 176b of the second louver 176 and the duct plate 52. As a result, the first flow rate of the cool air blown from the first opening 164 to the refrigerating chamber 26 can be made larger than the second flow rate of the cool air blown to the refrigerating chamber 26 from the second opening 166. Depending on the inclination angles of the first louver 174 and the second louver 176, the flow rate of the cool air blown out from the first opening 164 and the second opening 166 can be made different.

The third distance L3 between the tip 178b of the third louver 178 and the duct plate 52 is longer than the fourth distance L4 between the tip 180b of the fourth louver 180 and the duct plate 52. Therefore, similar to the relationship between the first flow rate and the second flow rate of the cool air by the first louver 174 and the second louver 176, the third flow rate of the cool air blown out from the third opening 168 to the refrigerating chamber 26 is changed from the fourth opening 170. It can be made larger than the fourth flow rate of the cool air blown into the refrigerating chamber 26. Depending on the inclination angles of the third louver 178 and the fourth louver 180, the flow rate of the cool air blown out from the third opening 168 and the fourth opening 170 can be made different.

(Fourth embodiment)
A fourth embodiment will be described with reference to FIG. In the fourth embodiment, the points different from the second embodiment will be described, and the same points as the second embodiment will be designated by the same reference numerals and description thereof will be omitted.

The front plate 290 has a fine port (not shown) for passing cold air. The front plate 290 is arranged closer to the front surface 26a side of the refrigerating chamber 26 than the duct plate 52. The front plate 290 extends vertically and horizontally. The front plate 290 is arranged so as to overlap the first opening 164, the second opening 166, the third opening 168, and the fourth opening 170. Therefore, even when the refrigerating chamber 26 is viewed from the front, the first opening 164, the second opening 166, the third opening 168, and the fourth opening 170 cannot be seen by the front plate 290. As a result, the design of the refrigerator compartment 26 can be improved.
