Specifically, the right end portion of the constricted portion 38 continues to the right closed portion 39R. Further, the left end portion of the constricted portion 38 continues to the left closing portion 39L. Therefore, the opening width of the central opening 42 of the second outlet element 32 is slightly smaller than the opening width of the slit 47 of the first outlet element 31, and the opening width of the right first opening 41R is slightly smaller than the opening width of the right first opening 41R. The width of the left first opening 41L is slightly smaller than the total width of the two openings 45R and the right blocking part 39R, and the opening width of the left first opening 41L is the total width of the left second opening 45L and the left blocking part 39L. slightly smaller than the dimensions.

Further, the first outlet element 31 of the steam discharge device 1 according to the present embodiment includes a plurality of blades 51 that direct the wind to the front side of the housing 2 and to the left and right sides.

The plurality of blades 51 extend closer to the cross flow fan 5 than the partition plate 37 dividing the first outlet element 31 and the second outlet element 32 . That is, the partition plate 37 extends from the side of the outlet opening 36 of the blower outlet 3 toward the cross-flow fan 5, but does not reach the inlet opening 35 of the blower outlet 3 and is discontinued. The plurality of blades 51 extend from the side of the outlet opening 36 of the blower outlet 3 toward the cross-flow fan 5 and reach the inlet opening 35 of the blower outlet 3 .

The plurality of blades 51 are tilted more toward the center of the first outlet element 31 as they are closer to the respective ends (the right end and the left end) of the first outlet element 31 . In addition, the plurality of blades 51 are laid down without being overlapped in the front-rear direction (front-rear direction) of the housing 2 .

It suffices if there are two or more blades 51 . The plurality of blades 51 are, for example, a first blade 51a, a second blade 51b, a third blade 51c, and a fourth blade 51d. The road is divided into 5 in the width direction. The first blade 51a to the fourth blade 51d are arranged from the right end of the first outlet element 31 toward the center. In other words, the first slat 51 a is closest to the right end of the first outlet element 31 and the fourth slat 51 d is closest to the center of the first outlet element 31 .

The second outlet element 32 includes a support 52 that reinforces the right second opening 45R directly below the right first louver 51a, and a left second opening 45L that reinforces the left first louver 51a. a strut 52; The strut 52 is provided at the edge of the exit opening 36 of the right second opening 45R. A support 53 is also provided at the edge of the outlet opening 36 of the central opening 42 of the second outlet element 32 .

The first outlet element 31 blows part of the air blown by the cross-flow fan 5 to the partitioned space S of the shelf 100 through the narrow gap 47 of the constricted portion 38, the first right opening 41R, and the first left opening 41L. A larger amount of air blown out from the first outlet element 31 is distributed to the right first opening 41R and the left first opening 41L than to the central portion 31a where the throttle portion 38 is located. The air blown out from the narrow gap 47 of the constricted portion 38 goes to the front of the outlet portion 3 (solid line arrow f1 in FIG. 4). The air blown out from the first right opening 41R and the first left opening 41L is divided into the left and right sides of the housing 2 and directed toward the side wall 103 of the shelf 100 (solid arrow f2 in FIG. 4). In particular, the plurality of blades 51 with different inclinations radially diffuse the air blown from the first right opening 41R and the first left opening 41L toward the side wall 103 of the shelf 100 .

On the other hand, the second outlet element 32 blows out the remainder of the air blown by the cross-flow fan 5 from the central opening 42, the right second opening 45R, and the left second opening 45L to the partition space S of the shelf 100. The blocking portion 39 blocks the outflow of air. The air blown out from the central opening 42 goes to the front of the outlet 3 (solid arrow f3 in FIG. 4). The air blown out from the second right opening 45R and the second left opening 45L is divided into the left and right sides of the housing 2 and directed toward the side wall 103 of the shelf 100 (solid arrow f4 in FIG. 4). Note that the right second opening 45R and the left second opening 45L are provided with the blocking portion 39, and thus have a narrower opening width than the right first opening 41R and the left first opening 41L. Therefore, the air blown out from the second right opening 45R and the second left opening 45L is limited to a narrow range of both ends 32b of the second outlet element 32. As shown in FIG.

As shown in FIGS. 4 and 5, when the air blown out from the first outlet element 31 and the air blown out from the second outlet element 32 are overlapped, the steam discharge device 1 according to the present embodiment has a partitioned space S. It can be seen that the air flows over a wide area. Such an air flow efficiently discharges the steam in the partitioned space S toward the front of the partitioned space S.

Thus, the steam discharge device 1 according to this embodiment includes the first outlet element 31 and the second outlet element 32 arranged in the height direction of the housing 2 . Both end portions 31b of the first outlet element 31, both end portions 32b of the second outlet element 32, and the central portion 32a of the second outlet element 32 are open. The central portion 31 a of the first outlet element 31 is provided with a narrowed portion 38 whose opening height is smaller than that of the opening of the central portion 32 a of the second outlet element 32 . The second outlet element 32 comprises a closure portion 39 between the central portion 32a and each end portion 32b. Therefore, the steam discharge device 1 distributes the air blown from the cross-flow fan 5 to the first outlet element 31 and the second outlet element 32, and the first outlet element 31 and the second outlet element 32 By synthesizing different air flows therebetween, air flows diffusing toward the top plate 102 and the side wall 103 of the partitioned space S are produced, and the steam is discharged from the partitioned space S efficiently. That is, the steam discharge device 1 uses a smaller cross-flow fan 5 than the conventional steam discharge device that blows air substantially uniformly in a direction perpendicular to the rotation center line of the cross-flow fan. An air flow can be created that exhausts the vapor over a wider area.

Further, the steam discharge device 1 according to the present embodiment includes the constricted portion 38 and the closed portion 39 that are partially connected to each other. Therefore, in the steam discharge device 1, between the right side first opening 41R of the first outlet element 31 and the central opening 42 of the second outlet element 32, and between the left side first opening 41L and the second outlet Air flow between the central opening 42 of the element 32 and the central opening 42 of the second outlet element 32 can be prevented to prevent flow turbulence and vapor exhaust as intended.

Furthermore, the steam discharge device 1 according to the present embodiment includes a plurality of blades 51 that direct the wind to the front side of the housing 2 and to the left and right sides. Therefore, the steam discharge device 1 can reliably spread the air blown from the cross-flow fan 5 over a wider range of the partitioned space S. As shown in FIG.

In addition, the steam discharge device 1 according to the present embodiment includes a plurality of blades 51 that fall more toward the center of the first outlet element 31 as they are closer to the respective ends of the first outlet element 31 . . Therefore, the steam discharge device 1 can radially diffuse the air blown from the cross-flow fan 5 into the partition space S. As shown in FIG.

As described above, according to the steam discharge device 1 according to the present embodiment, it is possible to reduce the width dimension of the partitioned space S of the shelf 100, and the side wall 103 side of the partitioned space S of the shelf 100 Efficient discharge of steam flowing to
