  However, in the refrigeration / refrigeration showcase described in Patent Document 1, the dehumidifying material is configured to rotate along a rotation axis extending in the front-rear direction of the case body. For this reason, when the dehumidifying material is formed so as to increase in the left-right direction of the case body other than the front-rear direction, the dehumidifying material is increased in the left-right direction due to the restriction that the dehumidifying material is rotated along the rotation axis extending in the front-rear direction. It is necessary to secure a space in which the dehumidifying material is arranged not only in the horizontal direction of the case body but also in the vertical direction. For this reason, in the said patent document 1, there exists a problem that it is difficult to enlarge a dehumidifier in the left-right direction, suppressing the enlargement of a case main body.

  The present invention has been made in order to solve the above-described problems, and one object of the present invention is to prevent moisture adsorbing portions in the left-right direction while suppressing an increase in the size of the case body in the vertical direction and the front-rear direction. It is to provide a showcase that can be enlarged.

  A showcase according to one aspect of the present invention is formed to extend in the left-right direction, and includes a display shelf on which merchandise is displayed, and an evaporator-side channel portion and a condenser-side channel portion through which air flows. A main body, an evaporator disposed inside the evaporator-side flow path section, a condenser disposed inside the condenser-side flow path section, an evaporator-side flow path section, and a condenser-side flow path section. A moisture adsorbing portion that is disposed in a communicable position and is disposed in the case main body so as to be rotatable around a rotation axis extending in the left-right direction of the case main body.

  In the showcase according to one aspect of the present invention, as described above, the moisture adsorbing portion is disposed in the case main body so as to be rotatable around the rotation axis extending in the left-right direction of the case main body. This increases the size of the case body in directions other than the left-right direction (vertical direction and front-rear direction) even when the moisture adsorbing portion is increased in the left-right direction, unlike when rotating around the rotation axis extending in the front-rear direction of the case body. There is no need to let them. Thereby, a moisture adsorption part can be enlarged in the left-right direction, suppressing the enlargement of the up-down direction and the front-back direction of a case main body. In addition, by disposing the moisture adsorbing part at a position where it can communicate with the evaporator-side channel part and the condenser-side channel part, the moisture content of the air flowing through the evaporator-side channel part and the condenser-side channel part Can be adjusted.

  In the showcase according to the above aspect, the moisture adsorbing portion is preferably formed to extend in the left-right direction of the case body. If comprised in this way, the water | moisture content of the air which distribute | circulates an evaporator side flow-path part and a condenser side flow-path part can be adjusted in the left-right direction wide range of a case main body.

  In the showcase according to the above aspect, the case main body preferably further includes a wall portion that separates the evaporator-side flow channel portion and the condenser-side flow channel portion and has a hole portion in which the moisture adsorption portion is disposed. In addition, the cross section orthogonal to the rotation axis has a rectangular shape, and the moisture adsorbing portion having the rectangular shape in the cross section is located in the gap between the wall portion and the moisture adsorbing portion in a state of being disposed in the hole portion. The partition part provided in is included. If comprised in this way, the clearance gap between the water | moisture-content adsorption | suction part and wall part which arises inevitably by rotating a water | moisture-content adsorption part of a rectangular shape in a cross section can be block | closed with a partition part. As a result, the air flowing through the condenser-side flow channel portion and the evaporator-side flow channel portion leaks to the evaporator-side flow channel portion side and the condenser-side flow channel portion side through the holes. Thus, mixing of the air flowing through each of them can be suppressed. As a result, the air tightness of the evaporator-side flow path portion and the condenser-side flow path portion can be improved, so that the ability of moisture adsorption and moisture removal in the moisture adsorption portion can be improved. Further, by providing the partition part in the moisture adsorption part, it is possible to suppress the partition part from contacting the moisture adsorption part as compared with the case where the partition part is provided in the wall part. Thereby, it can suppress that a moisture adsorption part wears.

  In this case, preferably, the moisture adsorbing section includes a flow path section that extends in a direction orthogonal to the rotation axis and through which air flows, and the partition section includes an inlet side and an outlet side of the flow path section in the moisture adsorption section. At least one of these is provided so as to extend in substantially the same direction as the direction in which the flow path portion extends. If comprised in this way, when a partition part is provided in the inflow port side of a flow-path part, it can suppress that the air mixed in the inflow port of a flow-path part flows in by a partition part. Moreover, when a partition part is provided in the outflow port side of a flow-path part, it can suppress that the air which flowed out from the outflow port of a flow-path part is mixed by a partition part. By these, since it can suppress that air is mixed more by a partition part, the airtightness of an evaporator side flow path part and a condenser side flow path part can be improved more. As a result, the ability of moisture adsorption and removal of the adsorbed moisture in the moisture adsorption unit can be further improved. Moreover, it can suppress that the flow of the air which distribute | circulates a flow path part by a partition part is obstructed by providing a partition part so that it may extend in the substantially same direction as the direction where a flow path part is extended.

  In the configuration in which the moisture adsorbing portion includes the partition portion, the partition portion preferably extends in substantially the same direction as the direction in which the channel portion extends on the inlet side and the outlet side of the channel portion in the moisture adsorption portion. A pair is provided. If comprised in this way, while being able to suppress that the air mixed in the inlet of a flow-path part flows in by the partition part by the side of the inlet of a flow-path part, on the outlet side of a flow-path part By the partition part, it can suppress that the air which flowed out from the outflow port of a flow-path part is mixed.

  In the configuration in which the partition portion is provided so as to extend in substantially the same direction as the direction in which the flow path portion extends, the moisture adsorption portion preferably further includes a boundary portion extending in the left-right direction at the center of the moisture adsorption portion, The passage portion is formed on one side of the boundary portion, and is formed on the other side of the boundary portion, the first flow passage portion communicating with either the evaporator side flow passage portion or the condenser side flow passage portion, A second flow path portion that communicates with either the evaporator-side flow path portion or the condenser-side flow path portion, and the moisture adsorbing portion rotates around the rotation axis so that the first flow path portion communicates. The tip and the communication destination of the second flow path part are switched, and the partition part is provided so as to extend in the left-right direction along the boundary part. If comprised in this way, it will connect in a 1st flow path part and a 2nd flow path part (Evaporator side flow path part or a condenser side flow path, blocking | closing the clearance gap between a water | moisture-content adsorption | suction part and a wall part by a partition part. Part) can be switched. Thereby, the moisture adsorbed when communicating with the evaporator-side flow channel portion can be removed when communicating with the condenser-side flow channel portion while suppressing the mixing of air.

  According to the present invention, as described above, the moisture adsorbing portion can be enlarged in the left-right direction while suppressing the increase in size of the case body in the up-down direction and the front-rear direction.

Moreover, each member of the refrigerator unit 10 is connected via the refrigerant | coolant piping 10a through which a refrigerant | coolant distribute | circulates.

  The compressor 11 has a function of compressing the gas refrigerant sucked from the low pressure side in the refrigeration cycle and discharging it to the high pressure side. The condenser 12 has a function of cooling the refrigerant in the superheated gas state circulating inside using the condenser side air blown by the blower 13 (see FIG. 3). Thereby, the refrigerant that has passed through the condenser 12 is condensed (liquefied). Then, the refrigerant flows into the expansion means 20 through the refrigerant pipe 10a.

  The expansion means 20 has a function of expanding and reducing (reducing pressure) the refrigerant cooled (liquefied) by the condenser 12 and supplying the refrigerant to the evaporator 21. The evaporator 21 has a function of cooling the evaporator-side air blown by the blower 22 (see FIG. 3) by evaporating (vaporizing) the gas-liquid two-phase refrigerant supplied from the expansion means 20. ing. Moreover, the refrigerant | coolant after the evaporation in the evaporator 21 is returned to the compressor 11 via the refrigerant | coolant piping 10a.

  Thus, in the refrigerator unit 10, the refrigerant discharged from the compressor 11 flows in the order of the condenser 12, the expansion means 20, and the evaporator 21 in the order of the arrow P and is returned to the compressor 11. Is configured to repeat. At this time, the showcase 100 is configured such that the display shelf 2 is maintained at a predetermined cooling temperature by operating the refrigerator unit 10.

  Next, the configuration of the case body 1 will be described with reference to FIGS. 1 and 3 to 5.

  As shown in FIG. 1, the case body 1 is formed to be shorter in the front-rear direction (X direction) than in the left-right direction (Y direction). Further, as shown in FIG. 3, the case body 1 is provided with a plurality of display shelves 2 on which products are displayed, and flow path portions 3 and 4 through which air flows. The plurality of display shelves 2 are arranged at predetermined intervals in the vertical direction (Z direction). Further, the plurality of display shelves 2 and the flow paths 3 and 4 are both formed to extend in the left-right direction of the case body 1 (Y direction, see FIG. 1). The flow path portions 3 and 4 are examples of the “evaporator side flow path portion” and the “condenser side flow path portion” of the present invention, respectively.

  The compressor 11 and the condenser 12 (see FIG. 2) described above are disposed in the flow path section 3. Further, the expansion means 20 and the evaporator 21 (see FIG. 2) described above are disposed in the flow path section 4.

  The flow path part 3 is comprised from the 1st flow path part 3a provided in the downward direction (Z2 side) of the display shelf 2, and the 2nd flow path part 3b provided in the back (X2 side) of the display shelf 2. ing. The first flow path portion 3a is formed so as to extend in the front-rear direction (X direction), and the second flow path portion 3b is formed so as to extend in the vertical direction (Z direction).

The first flow path part 4a is formed to extend in the front-rear direction along the first flow path part 3a, and the second flow path part 4b extends in the vertical direction along the second flow path part 3b. It is formed as follows.

  Here, in the flow path part 3, the air (evaporator side air) is supplied from the first flow path part 3 a of the flow path part 3 via the intake port 1 a provided in the front part (X1 side) of the case body 1.

Thereafter, the cooled evaporator-side air is supplied to a plurality of display shelves 2 from supply holes 5a, which will be described later, and is also downward from a spout 1b provided above the display shelves 2 of the case body 1 (Z1 side). It flows out toward (Z2 side). Note that the evaporator-side air that has flowed out of the jet outlet 1b flows in front of the display shelf 2, thereby functioning as an air curtain that suppresses the entry of air from the outside to the display shelf 2. . Then, part of the air supplied to the plurality of display shelves 2 and the air as the air curtain flows again into the flow path portion 3 from the intake port 1a. Here, the air that flows into the flow path portion 3 from the intake port 1a includes outside air (outside air) that contains more moisture than the air that flows out from the jet port 1b or the like.

  Moreover, in the flow path part 4, the air (condenser side air) passes through the filter part 1 c provided on the front part (X1 side) and the lower part (Z2 side) of the case body 1. It flows into the condenser 12 of the 1 flow path part 4a. Then, the condenser side air flows out to the downstream side of the condenser 12 while being heated by the condenser 12.

To be released.

  The case body 1 includes heat insulating walls 5, 6a, 6b, 7a and 7b having heat insulating properties. Here, the heat insulating wall 5 extending in the vertical direction (Z direction) separates the rear portion of the display shelf 2 extending in the vertical direction and the second flow path portion 3b from each other. Thereby, the heat distribution is restricted between the display shelf 2 and the second flow path portion 3b. The heat insulating wall 5 is provided with a supply hole 5a for supplying the evaporator side air to each of the plurality of display shelves 2.

The heat insulation walls 7 a and 7 b restrict the heat flow between the flow path portion 4 and the outside of the case body 1.

  Moreover, the hole 6c which penetrates the heat insulation wall 6b is formed in the heat insulation wall 6b. Thereby, the hole 6c is formed so as to connect the second flow path portion 3b and the second flow path portion 4b. The hole 6 c connects the upstream side of the evaporator 21 in the second flow path part 3 b of the flow path part 3 and the second passage part 4 b of the flow path part 4 downstream of the condenser 12. Is formed. The hole 6c is formed so as to extend in the left-right direction of the case body 1 (see FIG. 1).

As shown in FIG. 1, the moisture adsorbing portion 30 is formed so as to extend in the left-right direction over substantially the entire left-right region where the flow path portions 3 and 4 are formed. And the water | moisture-content adsorption | suction part 30 is comprised so that rotation around the rotating shaft line A extended in the left-right direction is possible. The rotation axis A extends in the left-right direction so as to pass through the approximate center of the moisture adsorbing portion 30 having a rectangular shape in cross section. In addition, the moisture adsorbing unit 30 is configured to rotate half a turn (about 180 degrees) every predetermined time by a driving unit (not shown) such as a motor.

  Hereinafter, the configuration of the moisture adsorption unit 30 in a stationary state, not the moisture adsorption unit 30 in the rotation state (during rotation) will be described.

It is formed to be slightly larger than the length L2. Further, the distance L3 between the wall surface on the front side (X1 side) of the flow path portion 3 (the rear surface of the heat insulation wall 5) and the wall surface on the rear side (X2 side) of the flow path portion 4 (the front surface of the heat insulation wall 7b) It is formed to be longer than the length L2 of the diagonal line of the portion 30. As a result, even when the moisture adsorbing part 30 rotates around the rotation axis A, the heat insulating walls 5, 6 b and 7 b are not located in the rotation path B of the moisture adsorbing part 30. As a result, the moisture adsorbing portion 30 and the heat insulating walls 5, 6b and 7b are configured not to contact each other. Therefore, it is possible to suppress the moisture adsorbing portion 30 from being worn due to the moisture adsorbing portion 30 coming into contact with the heat insulating walls 5, 6b, or 7b, and the passage portion 31 described later from being blocked. .

  In the present embodiment, as shown in FIG. 4, the moisture adsorbing portion 30 is disposed in the hole 6 c of the heat insulating wall 6 b and is located in a gap between the heat insulating wall 6 b and the moisture adsorbing portion 30. The partition part 35 is provided. Specifically, the pair of partition portions 35 are formed of rectangular plate members that are long in the left-right direction (Y direction).

As a result, the distance L4 is formed to be slightly smaller than the vertical length L1 of the hole 6c. Thereby, the partition parts 35a and 35b are positioned so as to fill the upper gap and the lower gap between the hole 6c and the moisture adsorbing part 30, respectively.

  Further, as shown in FIG. 5, four fixing portions 36 for fixing the pair of partition portions 35 are provided in the cylindrical portion 34 of the moisture adsorption portion 30.

Further, the fixing portions 36 a and 36 b provided at the upper end (Z1 side) are formed in a semi-elliptical shape so as to extend upward from the upper end portion of the cylindrical portion 34. Similarly, the fixing parts 36c and 36d provided at the lower end (Z2 side) are formed in a semi-elliptical shape so as to extend downward from the lower end of the cylindrical part 34. The fixing portion 36 may be formed by joining a semi-elliptical sheet metal to the cylindrical portion 34 by welding or the like, or the shape of the cylindrical portion 34 itself is previously set to a shape having the shape of the fixing portion 36. It may be formed.

Here, the distance L5 between the half ellipse of the fixed part 36a (36b) of the rotation axis A and the half ellipse of the fixed part 36c (36d) is smaller than the diagonal length L2 of the moisture adsorbing part 30. It is configured as follows.

  Further, the plurality of flow path portions 31 are arranged on one side in the X direction with a boundary portion 32a constituted by a plate member 32 extending in the left-right direction and the up-down direction at the approximate center in the front-rear direction (X direction). It is divided into a plurality of first flow path portions 37 and a plurality of second flow path portions 38 arranged on the other side in the X direction. Note that partition portions 35a and 35b are respectively provided immediately above and immediately below the boundary portion 32a.

  Here, the fluid adsorbing part 30 is rotated halfway around the rotation axis A extending in the left-right direction (about 180 degrees), whereby the flow path part 31 (the first flow path part 37 and the second flow path part 38) communicates. It is configured so that the tip is switched.

  The half-rotation of the moisture adsorption unit 30 is performed every predetermined time, so that the communication destinations of the plurality of first flow path portions 37 and the communication destinations of the plurality of second flow path portions 38 are It is configured to switch between four. In addition, before and after the rotation of about 180 degrees, the extending direction of the first flow path portion 37 and the second flow path portion 38 does not change in the vertical direction.

  Thereby, when the flow path portion 31 (the first flow path portion 37 or the second flow path portion 38) communicates with the flow path portion 3, the moisture of the evaporator side air is adsorbed by the moisture adsorbent, The evaporator side air flows out from the flow path part 31 of the moisture adsorption part 30 in a dry state (dehumidified state). Thereby, it is suppressed that the moist air penetrate | invades into the evaporator 21 located in the downstream (Z1 side) rather than the water | moisture-content adsorption | suction part 30. FIG.

  On the other hand, the condenser heated by the condenser 12 when the moisture adsorbing part 30 rotates halfway and the flow path part 31 (the first flow path part 37 or the second flow path part 38) communicates with the flow path part 4. When the side air flows through the flow path portion 31, the moisture adsorbed by the moisture adsorbing material is removed and the moisture adsorbing material is regenerated, and the condenser side air moistened by the removed moisture becomes the moisture adsorbing portion. It flows out from the 30 channel portions 31 to the channel portion 4. Then, the wet condenser side air is discharged to the outside from the discharge hole 1 d (see FIG. 3) of the case body 1.

  By repeating the adsorption and removal of moisture every predetermined time, moisture adsorption and moisture removal (regeneration of the moisture adsorbent) are continuously performed.

  Here, due to the partition portion 35 on the Z1 side, the moist air on the flow channel portion 4 side enters the flow channel portion 3 side through the gap between the heat insulating wall 6b and the downstream side (Z1 side) of the moisture adsorbing portion 30. By being suppressed, warm and humid air is suppressed from flowing into the evaporator 21. As a result, condensation in the evaporator 21 is suppressed. Furthermore, the Z1 side partition part 35 suppresses the cold air on the flow path part 3 side from flowing out from the gap between the heat insulating wall 6b and the downstream side of the moisture adsorption part 30 to the flow path part 4 side. Cool air is prevented from being discharged from the discharge hole 1d.

  Furthermore, mixing of warm air on the flow path unit 4 side and cold air on the flow path unit 3 side is suppressed by the partition section 35 on the Z2 side.

  In addition, as shown in FIG. 4, moisture adsorption on the upstream side (lower side) of the second flow path part 3 b and the upstream side (lower side) of the second flow path part 4 b with respect to the moisture adsorption part 30, respectively. Guide portions 39 and 40 for guiding the air flow to the portion 30 are provided. Specifically, the lower portion 39a of the guide portion 39 on the second flow path portion 3b side is attached to the front side (X1 side) inner surface (the X2 side surface of the heat insulating wall 5) of the second flow path portion 3b. . Similarly, the lower part 40a of the guide part 40 on the second flow path part 4b side is attached to the inner surface (the X1 side face of the heat insulating wall 7b) on the rear side (X2 side) of the second flow path part 4b. The guide portions 39 and 40 are formed to extend in the left-right direction so as to correspond to the moisture adsorption portion 30.

  The upper part 39b of the guide part 39 is formed so that the moisture adsorbing part 30 side (upper side) is inclined toward the inner side (X2 side) of the flow path part 3, and the upper end part of the upper part 39b is the moisture adsorbing part. It is located near the front and lower end portions of 30. Similarly, the upper part 40b of the guide part 40 is formed so that the moisture adsorption part 30 side (upper side) is inclined toward the inner side (X1 side) of the flow path part 4, and the upper end part of the upper part 40b is moisture adsorption. It is located in the vicinity of the rear and lower end portions of the portion 30. Thereby, the guide parts 39 and 40 are each configured to guide substantially all of the air flowing through the flow path part 3 and the air flowing through the flow path part 4 to the moisture adsorption part 30.

  Further, a guide part 41 for guiding the air flowing out from the flow path part 31 of the moisture adsorption part 30 to the evaporator 21 is provided on the downstream side (upper side) of the second flow path part 3 b with respect to the moisture adsorption part 30. It has been.

  In the present embodiment, the following effects can be obtained.

  In the present embodiment, as described above, the moisture adsorbing portion 30 is disposed in the case body 1 so as to be rotatable around the rotation axis A extending in the left-right direction (Y direction) of the case body 1. Thus, unlike the case of rotating around the rotation axis A extending in the front-rear direction (X direction) of the case main body 1, the case main body 1 is moved in a direction other than the left-right direction (up and down) even if the moisture adsorbing portion 30 is increased in the left-right direction. There is no need to increase the size in the direction (Z direction) and the front-rear direction. Thereby, the water | moisture-content adsorption | suction part 30 can be enlarged in the left-right direction, suppressing the enlargement of the up-down direction of the case main body 1 and the front-back direction. Further, by arranging the moisture adsorbing portion 30 at a position where the moisture adsorbing portion 30 can communicate with the channel portion 3 and the channel portion 4, the moisture of the air flowing through the channel portions 3 and 4 can be adjusted.

  In the present embodiment, the moisture adsorbing portion 30 is formed so as to extend in the left-right direction of the case body 1. Thereby, the water | moisture content of the air which distribute | circulates the flow-path parts 3 and 4 can be adjusted in the left-right direction wide range of the case main body 1. FIG.

  Moreover, in this embodiment, the partition part 35 is provided in the water | moisture-content adsorption part 30 which has a rectangular shape in a cross section so that it may be located in the clearance gap between the heat insulation wall 6b and the water | moisture-content adsorption part 30 in the state arrange | positioned in the hole 6c. . Thereby, the clearance gap between the water | moisture-content adsorption | suction part 30 and the heat insulation wall 6b which arises inevitably by rotating the water | moisture-content adsorption part 30 of a rectangular shape in a cross section can be block | closed by the partition part 35. FIG. As a result, the air flowing through the flow path section 4 and the flow path section 3 is prevented from being mixed due to the leakage of the air to the flow path section 3 side and the flow path section 4 side, respectively. Therefore, the airtightness of the flow path part 3 and the flow path part 4 can be improved. As a result, the moisture adsorption and moisture removal performance (dehumidification performance) in the moisture adsorption unit 30 can be improved. Further, by providing the pair of partition portions 35 in the moisture adsorption portion 30, it is possible to suppress the pair of partition portions 35 from coming into contact with the moisture adsorption portion 30 as compared to the case where the partition portions are provided in the heat insulating wall 6b. . Thereby, it can suppress that the moisture adsorption part 30 is worn.

  In the present embodiment, the partition portions 35a and 35b are substantially the same as the vertical direction (Z direction) in which the flow channel portion 31 extends in the moisture adsorption portion 30 on the inlet 31a side and the outlet 31b side of the flow channel portion 31. They are provided so as to extend in the same direction. If comprised in this way, while being able to suppress that the air mixed in the inflow port 31a of the flow-path part 31 flows in by the partition part 35a by the side of the inflow-port 31a of the flow-path part 31, a flow-path part It is possible to prevent the air flowing out from the outlet 31b of the flow path portion 31 from being mixed by the partition portion 35b on the outlet 31b side of the 31. Further, by providing the partition part 35 (35a and 35b) so as to extend in substantially the same direction as the vertical direction in which the flow path part 31 extends, the flow of air flowing through the flow path part 31 is inhibited by the partition part 35. Can be suppressed.

  Moreover, in this embodiment, when the water | moisture-content adsorption | suction part 30 rotates to the surroundings of the rotating shaft A, it is comprised so that the communication destination of the 1st flow path part 31 and the communication destination of the 2nd flow path part 31 may switch. Furthermore, the partition part 35 (35a and 35b) is provided so that it may extend in the left-right direction (Y direction) along the boundary part 32a. Accordingly, the communication destination (the flow path portion 3 or the flow path portion 4) is connected in the first flow path portion 37 and the second flow path portion 38 while closing the gap between the moisture adsorption portion 30 and the heat insulating wall 6 b by the partition portion 35. Each can be switched. Accordingly, moisture adsorbed when communicating with the flow path portion 3 can be removed when communicating with the flow path portion 4 while suppressing air from being mixed.
