<Dehumidification unit>
FIG. 3 is a perspective view of the dehumidifying unit.

  In FIG. 3, the dehumidifying unit 3 includes an adsorbing element 31, a heater 32, a second blower 33, a blower pipe 34, a heat exchange unit 35, and a drain port 38 (see FIG. 4).

  The adsorbing element 31 is a honeycomb structure, and is formed into a disk shape from a porous material obtained by mixing and kneading zeolite powder, a binder, and an expansion agent. The binder here is selected from, for example, thermoplastic resins such as modified PPE, polypropylene, polystyrene, and ABS resin. The expansion agent expands when the honeycomb structure is formed, thereby forming innumerable bubbles. For this reason, the adsorption | suction element 31 has high adsorptivity with respect to a water | moisture content.

  The heater 32 is disposed to face a part of the back side of the adsorption element 31. The heater 32 has a substantially fan shape and is provided at a position covering about one-sixth of the back side of the adsorption element 31.

  The 2nd air blower 33 has a shape which protrudes toward the back side from the upper part of the adsorption | suction element 31. As shown in FIG. The heater 32 and the second blower 33 are connected by a first blower pipe 34a so that air can be circulated. When the second blower 33 is operated, an air flow is formed, and the first blower pipe 34a flows in the direction indicated by the arrow. The air flowing in the vicinity of the heater 32 is heated there to become high-temperature air.

  The air duct 34 has a first air duct 34a, a second air duct 34b, a third air duct 34c, and a fourth air duct 34d. The high-temperature air heated by the heater 32 travels from the back side of the opposing adsorption element 31 toward the front side in the thickness direction of the adsorption element 31 and flows out from the front side of the adsorption element 31. Here, in the region where the high-temperature air passes in the region of the adsorption element 31, the retained moisture is released along the air flow by the second blower 33 by being warmed by the high-temperature air.

  The air that has passed through the adsorbing element 31 from the back side toward the front side becomes high-temperature and high-humidity air by containing moisture released from the adsorbing element 31, and proceeds to the second blower pipe 34b. The second air duct 34b is formed so as to cover a part of the adsorbing element 31 from the front side in order to direct almost all of the high-temperature and high-humidity air that has passed through the adsorbing element 31 to the third air duct 34c without resistance. Has been. The second blower pipe 34b has a substantially fan shape when viewed from the front, and is provided at a position sandwiching the same portion of the adsorption element 31 together with the heater 32 described above, and about 1/6 of the front side of the adsorption element 31 is provided. Covering.

  The third blower pipe 34c guides the high-temperature and high-humidity air flowing from the second blower pipe 34b to the right side when viewed from the front along the outer circumference of the adsorption element 31 in the radial direction. The third blower pipe 34c is provided with a plurality of long holes 35a penetrating in the front-rear direction and is part of the air flow path A. The high-temperature and high-humidity air flowing through the third blower pipe 34c flows while being in contact with the wall surface forming the long hole 35a. For this reason, the air passing through the air flow path A including the long hole 35a exchanges heat with the high-temperature and high-humidity air flowing through the third blower pipe 34c, and does not mix with each other. Takes heat away from the air flowing through. For this reason, the high-temperature and high-humidity air that has contacted the wall surface forming the long hole 35a is cooled, and dew condensation occurs inside the third blower pipe 34c on the wall surface forming the long hole 35a. The condensed water flows down into the tank 40 through a drain pan 50 (described later) through a drain port 38 penetrating in the vertical direction shown in FIG.

  The fourth blower pipe 34 d communicates the third blower pipe 34 c and the second blower 33. The high-temperature and high-humidity air passing through the third blower pipe 34c is brought into contact with the wall surface forming the plurality of elongated holes 35a and deprived of heat and moisture, and then passes through the fourth blower pipe 34d to the second blower 33. Inhaled.

  The long hole 35a is provided so as to surround a part of the outer side of the adsorption element 31 in the radial direction, and the heat exchange part 35 is formed by the plurality of long holes 35a. The dehumidifying unit 3 is formed with a flat region 3a in which the dimension in the thickness direction is set to substantially the same value, and the third blower pipe 34c and the heat exchange part 35 are included in the flat region 3a.

  FIG. 4 is a front view of the dehumidifying unit 3 viewed from the back side.

  In FIG. 4, the dehumidifying unit 3 further includes a drive motor 36. The drive motor 36 has a pinion gear 361. A driven gear 311 that meshes with the pinion gear 361 is provided on the outer periphery of the adsorption element 31. While the drive motor 36 is operating, the adsorption element 31 rotates by transmitting power to the driven gear 311 meshing with the pinion gear 361. Then, while the adsorption element 31 rotates, the air sucked into the main body casing 10 passes through the air flow path A, thereby passing a part of the adsorption element 31. When this air passes through the adsorbing element 31, the adsorbing element 31 adsorbs and holds moisture in the air that is about to pass through, and reduces the moisture in the air after passing. Then, as the adsorption element 31 continues to rotate, the portion of the adsorption element 31 that retains moisture moves to a position facing the heater 32 and is heated. As a result, a part of the adsorbing element 31 that retains moisture releases the retained moisture on the spot, and hardly retains moisture. And the adsorption | suction element 31 contacts the new air which passes the air flow path A by continuing rotation, and adsorb | sucks and hold | maintains a water | moisture content from this new air. Thus, the adsorption | suction and discharge | release of a water | moisture content can be repeated because the adsorption | suction element 31 rotates.

  In FIG. 1, a selection panel 11 capable of selectively inputting an air cleaning operation, a dehumidifying operation and a humidifying operation is provided on the uppermost surface of the main body casing 10. The selection panel 11 that receives this selection input is connected to the control unit 6 so as to be communicable. The selection panel 11 includes a selection button 37 capable of selecting rotation and stop of the adsorption element 31. When the selection button 37 is switched to an off state during the dehumidifying operation, the rotation of the adsorption element 31 is stopped and positively performed. Dehumidifying operation is stopped. At this time, since the heater 32 and the second blower 33 continue to operate, the high-temperature air circulates in the blower pipe 34. For this reason, since the air which flows through the air flow path A passes through the heat exchange part 35, it can be warmed and the warmed air can be discharge | released to harmony object space, Therefore A small-scale heating can be performed. At this time, heating / humidifying operation can be performed by simultaneously operating the humidifying unit 4 described later. In the present embodiment, the heating / humidifying operation mode is set in advance in the control unit 6 so that the heating / humidifying operation can be selected from the selection panel 11.

<Humidification unit>
FIG. 5 is a perspective view of the humidifying unit.

  In FIG. 5, the humidifying unit 4 is provided on the back side of the main body internal dehumidifying unit 3, and includes a vaporizing element 41, a water wheel 42, and a drive unit 43. The humidification unit 4 performs humidification by supplying water stored in the tank 40. The tank 40 is a water source used for humidifying air passing through the air flow path A, and is accommodated in the insertion space S of the main casing 10 so as to be detachable. When the water in the tank 40 is insufficient, the user pulls out the tank 40 from the tank outlet 12 of the main body casing 10 and replenishes the water in order to replenish the water for humidification. In the humidity control air cleaning device 1 of the present embodiment, the water that has been captured and stored in the tank 40 by exerting the function of the dehumidifying unit 3 can be used to demonstrate the humidifying function of the humidifying unit 4. Therefore, the replenishment frequency of water can be reduced compared with the conventional humidifier which performs only humidification.

  The vaporizing element 41 is a vaporizing member that is formed into a disk shape with a non-woven fabric and that evaporates water sent from the tank 40 by rotating. The vaporizing element 41 has a first gear 411 on the outer periphery, and the first gear 411 is rotated by the driving gear 43 rotating the driving gear 431. Since the vaporizing element 41 is disposed such that the lower end of the vaporizing element 41 is located above the water level in the full state of the tank 40, the vaporizing element 41 is not in direct contact with the water in the tank 40.

  FIG. 6 is a perspective view of the humidification unit 4 and the tank 40 as seen from the back side.

  In FIG. 6, the water turbine 42 is supported rotatably with respect to the tank 40 by the shaft 40 being instructed by a bearing 40 a provided in the tank 40. Then, the water turbine 42 rotates about the axis, so that the water in the tank 40 is captured by the portion located below the water surface in the tank 40 and pumped up to the portion on the water surface facing the vaporizing element 41. Water is supplied to the vaporizing element 41 such that the water pumped by the water 42 is released from the water wheel 42. Here, in order to reduce the dimension in the thickness direction of the humidifying unit 4 and to make the thickness of the humidity control air cleaning device 1 itself compact, the vaporizing element 41 and the water turbine 42 are in a positional relationship in which the axes of rotation are substantially parallel. Yes, adjacent to each other.

  Here, in order to carry the water of the tank 40 to the vaporizing element 41 located further upward while rotating about the axis, the water wheel 42 is recessed in the axial direction in the vicinity of the outer periphery on the back side of the water wheel 42. A plurality of substantially trapezoidal concave portions 421a are provided.

  FIG. 7 is an exploded perspective view of the water wheel 42.

  In FIG. 7, the water wheel 42 is formed by combining a wheel 421, a wheel cover 422, a second gear 423, and the like.

  The wheel 421 is formed with a plurality of recesses 421a that are recessed toward the back side so as to be arranged along the circumference.

  The wheel cover 422 is formed with a plurality of substantially trapezoidal holes 422a penetrating in the axial direction. The wheel 421 and the wheel cover 422 are combined in a positional relationship in which the plurality of recesses 421a of the wheel 421 are opposed to the plurality of holes 422a of the wheel cover 422, respectively. The size of the hole 422a is about half of the substantially trapezoidal shape that borders the vicinity of the upper portion of the recess of the recess 421a, and in the state where the wheel 421 and the wheel cover 422 are combined, the vicinity of the upper portion of the recess 421a is bordered. Approximately half of the approximately trapezoidal shape to be taken is covered, and approximately half is open. As a result, in the state where the wheel 421 and the wheel cover 422 are combined, a receiving groove that is depressed in the vertical direction can be formed between the wheel 421 and the wheel cover 422 depending on the rotational position, and It is possible to pump up.

  As shown in FIG. 6, the second gear 423 is a gear that meshes with the first gear 411 of the vaporizing element 41, and the rotation shaft 424 shared by the wheel 421, the wheel cover 422, and the second gear 423 is at the center of rotation. Is provided. The second gear 423, the wheel cover 422, and the wheel 421 are sequentially stacked and combined with the rotation shaft 424 as the same axis.

  As the water wheel 42 rotates, the concave portion 421a sequentially passes through the water in the tank 40 and repeats the operation of leaving the water surface. Here, when the concave portion 421a is submerged, water flows into the concave portion 421a through the hole 422a, and the receiving groove recessed in the vertical direction between the wheel 421 and the wheel cover 422 is submerged in a state where the interior is filled with water. Go out from.

  When the water wheel 42 further rotates and the receiving groove filled with water approaches the uppermost position, water in the receiving groove flows out downward through the hole 422a and passes through the uppermost position. Almost all water flows out. Since some momentum is added by gravity when the water flows out, the water flows out toward the back side so as to reach the front side of the vaporizing element 41 adjacent to the recess 421a.

  In FIG. 6, the rotation shaft 424 is rotatably supported by the bearing 40 a of the tank 40. Even if the height from the upper surface of the bottom of the tank 40 of the bearing 40a to the shaft core of the bearing 40a is the lowest level when the water turbine 42 is disposed, The concave portion 421a at the position is set so as to be submerged.

  Further, since the upper half of the bearing 40 a is open, when the tank 40 is pulled out from the main body casing 10, the user can take out the water wheel 42 from the tank 40 and clean it.

<Positional relationship between dehumidification unit and humidification unit>
FIG. 8 is a perspective view of a state in which the dehumidifying unit 3 and the humidifying unit 4 are combined.

  In FIG. 8, the humidifying unit 4 is disposed below the second blower 33 of the dehumidifying unit 3 so as to overlap each other in plan view. The vaporizing element 41 of the humidifying unit 4 faces the adsorbing element 31 of the dehumidifying unit 3 and the heat exchange unit 35 that is not visible in FIG. The water turbine 42 is disposed so as to be sandwiched between the vaporizing element 41 and the heat exchange unit 35 from the front-rear direction.

<Attachment / removal mechanism of vaporization element>
As shown in FIGS. 5 and 6, the vaporizing element 41 is formed in a shape that does not project the rotating shaft in the front-rear direction in order to facilitate removal from the main body casing 10.

  The vaporizing element 41 is supported by both gears 431 and 423 when the first gear 411 meshes with the drive gear 431 and the second gear 423. In order for the first gear 411 to maintain a stable posture, the drive gear 431 and the second gear 423 are positioned below the rotation axis of the first gear 411 and are on the surface of the vertical center line of the vaporizing element 41. They are located on opposite sides of each other. For this reason, the vaporizing element 41 can rotate stably even if it is not supported by the shaft, and when it is taken out from the main body casing 10, there is no protruding shaft, so that it can be easily caught without being caught inside the main body casing 10. It is taken out.

  Here, as shown in FIG. 1, the main body casing 10 is provided with a vaporizing element outlet 13 that opens by opening a rotary vaporizing member door 16. Thereby, the vaporizing element 41 can be taken out via the vaporizing element outlet 13 by opening the vaporizing member door 16. As a result, the user can take out and replace the vaporizing element 41.

Further, as shown in FIGS. 10, 11 and 12, the tank bottom surface 46 has a tank taper 46a which is inclined downward as it is away from the tank insertion surface 40s from a portion away from the tank insertion surface 40s by a predetermined distance. As shown in FIG. 19, the vicinity of the end of the tank bottom surface 46 opposite to the insertion side constitutes the lower edge of the tank outlet 12 of the main casing 10.

  As shown in FIG. 11 and FIG. 12, the tank take-out surface 47 constitutes the side surface on the right side of the tank 40 as viewed from the front, while the tank 40 is inserted into the insertion space S of the main body casing 10. A part of the right side of the front view is formed. Further, as shown in FIGS. 1, 5, etc., the tank extraction surface 47 is provided with a tank window portion 47 a that penetrates the tank extraction surface 47 in the plate thickness direction.

  A vessel shape is formed by the tank front surface 40f, the tank back surface 40b, the tank insertion surface 40s, the tank bottom surface 46, and the tank take-out surface 47, and the tank 40 can store water inside the vessel.

  As shown in FIGS. 1, 10, 11, and 12, the tank handle 48 is a groove that is recessed in a V shape below a tank extraction surface 47 that is the end opposite to the insertion side of the tank 40. It can be grasped by inserting a hand from below to above. The user can grasp the tank handle 48 to extract the tank 40 from the main body casing 10 or insert the tank 40 into the main body casing 10.

  As shown in FIGS. 10, 11 and 12, the tank rib 44 is a rib protruding so as to border the corner formed by the tank bottom surface 46 and the tank insertion surface 40s in the rear view, Two of the front tank rib 44f and the rear tank rib 44b on the back side are provided so as to extend in parallel to each other. Both the front tank rib 44f and the rear tank rib 44b on the back side have a portion extending further downward in the vertical direction from the lower surface side of the tank bottom surface 46, and constitute the lowest position (lower end) of the tank 40. Therefore, the tank 40 can be supported by contacting the floor while the tank 40 is placed on the floor.

  As shown in FIG. 19 which is a side cross section of the tank 40, the front tank rib 44 f and the rear tank rib 44 b are both inserted into the insertion space S of the main body casing 10 through the tank outlet 12. It has a contact portion X that slides up in contact with the lower edge of the outlet 12.

  The contact portion X is formed so as to be inclined so that almost all of the contact portion X including the vicinity of the height of the lower edge of the tank outlet 12 is raised toward the insertion side. Here, as shown in FIG. 19, almost all of the inclined shape of the contact portion X is curved. This contact portion X is provided at a position covering the insertion side lower end portion of the tank 40, and at least the tank beyond the upper surface of the tank bottom surface 46 from a lower position constituting the lower end of the tank 40 than the lower surface of the tank bottom surface 46. It is formed to extend to a position higher than the position of the height h5 + h4 of the upper surface of the main body bottom surface 15 in the vicinity of the outlet 12 (including the thickness h4 of the main body bottom surface 15 itself). Further, since this contact portion X forms an end portion on the insertion side of the tank bottom surface 46, the contact portion X is inclined with the vicinity of the lower end on the insertion side of the tank 40 as a fulcrum so that the side opposite to the insertion side of the tank 40 is slightly lifted. Even if it is inserted, it becomes easy to insert. Further, the contact portion X is elongated in the insertion direction for both the front tank rib 44f and the rear tank rib 44b.

  Further, both the front tank rib 44f and the rear tank rib 44b are located in the vicinity of the end portion on the insertion side of the tank 40 and on the extension of the contact portion X opposite to the insertion side. It has a tank resistance portion Y that acts as a resistance to the recess 15d (described later).

  The front tank ribs 44f and the rear tank ribs 44b on the back side have shapes that increase in width in the direction including the insertion side as they rise upward from the lower ends of the front tank ribs 44f and the rear tank ribs 44b on the rear side. The contact area between the floor G and the front tank rib 44f and the rear tank rib 44b on the back side is small, and the frictional resistance when the tank 40 slides on the floor G can be kept low. The portions that are not in contact with the floor G are formed by bending each portion with a predetermined radius of curvature.

  As shown in FIG. 19, the tank rib 44 has a height from the lower end of the tank rib 44 to the upper surface of the main body bottom surface 15 that is separated from the ground by the casters 19 of the main body casing 10 (the sum of the height h5 and the height h4). The edge on the insertion side until reaching the height of is formed so as to rise upward from the lower end toward the insertion side. For this reason, since there is no part which is not inclined to the insertion side in the middle, it becomes possible to avoid a situation in which resistance to insertion increases at the non-inclined part when the tank 40 described later is inserted. Yes.

  The tank rib 44 is positioned in the vicinity of the end of the tank bottom surface 46 on the insertion side, as shown in FIG. And it is provided to the height position exceeding the upper surface of the tank bottom face 46. Therefore, even when the tank 40 and the main body casing 10 are placed on the floor G, even if the lower surface of the tank bottom surface 46 supported by the tank rib 44 is lower than the upper surface of the main body bottom surface 15, Since it is provided to a height exceeding the upper surface of the tank bottom surface 15 and further to a height exceeding the upper surface of the main body bottom surface 15 of the main body casing 10, the insertion load of the tank 40 can be reduced.

  The longitudinal direction of the tank rib 44 is formed substantially parallel to the insertion side. For this reason, friction can be reduced compared with the structure in which the longitudinal direction of the upper and lower insertion assisting portions is formed perpendicular to the insertion side.

  The tank curved surface 45 has a front tank curved surface 45f and a back tank curved surface 45b, as shown in FIGS. The front tank curved surface 45f has a shape in which the corner formed by the tank insertion surface 40s and the tank front surface 40d is an R shape that smoothly connects both surfaces, and the R shape continues in the vertical direction. The back tank curved surface 45b has a shape in which the corner formed by the tank insertion surface 40s and the tank back surface 40b is an R shape that smoothly connects both surfaces, and this R shape continues in the vertical direction. By the front tank curved surface 45f and the back tank curved surface 45b, the vicinity of the insertion side end of the tank 40 has a shape in which the width of the horizontal component substantially perpendicular to the insertion side becomes narrower toward the insertion side. Yes. For this reason, since the width of the horizontal direction becomes narrow as it goes to the insertion side as a shape of the tank 40, when inserting the tank 40, it becomes easy to guide in the tank outlet 12 also about a horizontal direction.

  Moreover, as shown in FIG. 13 etc., the main body casing 10 is comprised by the main body bottom face 15 rather than the position of the edge comprised by the main body front surface 10f and the main body back surface 10b among the edges of the tank outlet 12. The edge position is formed so as to be recessed toward the insertion side by a predetermined recess distance h2. On the other hand, as shown in FIG. 13, from the end opposite to the insertion side of the front tank curved surface 45f and the back tank curved surface 45b described above, the insertion side end of the front tank rib 44f and the rear tank rib 44b on the back side. The predetermined thickness h <b> 3 until is shorter than the predetermined recess distance h <b> 2 that is the recess of the main body casing 10. Thus, when the tank 40 is inserted, the front tank curved surface 45f or the rear tank curved surface 45b is first brought into contact with the end of the main body casing 10 on the main body front surface 10f or the main body rear surface 10b on the tank outlet 12 side, so that the horizontal direction The position is guided, and thereafter, the position in the vertical direction is guided by the front tank rib 44f and the rear tank rib 44b on the back side.

  As shown in FIGS. 6, 9, and 12, the bearing 40 a extends upward from the upper surface side of the tank bottom surface 46 of the tank 40, has a shape in which the tip is slightly depressed downward, and the water wheel 42 The rotating shaft 424 is supported rotatably.

  As shown in FIGS. 6 and 9, the convex portion 40 c has a shape in which a part of the side surface of the tank 40 protrudes in the circumferential direction so as to correspond to the opening of the tank window portion 47 a of the tank extraction surface 47. It is a transparent resin molding part. The convex portion 40c is fitted into the tank window portion 47a so that the transparent convex portion is fitted into the tank window portion 47a which is a part of the tank extraction surface 47 constituting a part of the side surface of the main body casing 10. Through 40c, the water level in the tank 40 can be visually recognized even when the tank 40 is mounted.

  In addition, the main body casing 10 has the main body bottom face 15, as shown in FIG.1, FIG.9, FIG.10, FIG.11 and FIG. Further, casters 19 provided further below are provided at the four corners on the lower surface side of the main body bottom surface 15 to support the main body casing 10 at four points. Further, as shown in FIG. 1, the main body casing 10 includes a main body front surface 10 f that forms the front side of the main body casing 10, and a main body back surface 10 b that forms the back side of the main body casing 10. Here, the insertion space S provided for inserting the tank 40 into the main body casing 10 includes the upper surface side of the main body bottom surface 15, the rear surface of the main body front surface 10f, and the front surface side of the main body rear surface 10b. A space surrounded by a surface. As shown in FIG. 1, the insertion space S has a tank outlet 12 that opens in a substantially horizontal direction.

  Further, as shown in FIG. 13 to be described later, the main body casing 10 is inserted into the tank outlet 12 side end side of the main body bottom surface 15 more than the positions of the main body front surface 10f and the main body rear surface 10b side edge of the tank outlet 12 side. It is located inside by a predetermined depression distance h2 in the direction.

  Further, as shown in FIG. 19 described later, the main body bottom surface 15 of the main body casing 10 is recessed downward in the vicinity of the bottom surface opening side edge 15p constituting the tank outlet 12 side edge and in the vicinity of the bottom surface opening side edge 15p. And a bottom recess 15d. That is, the end of the tank 40 opposite to the insertion side of the front tank rib 44f or the rear tank rib 44b on the back side is located in the vicinity of the insertion side end of the tank 40. The bottom surface recess 15d provided on the upper surface side of the main body bottom surface 15 near the tank outlet 12 is in contact with the front tank rib 44f and the rear tank rib 44b on the rear surface, and faces the front tank rib 44f and the rear surface toward the opposite side to the insertion side. When the side rear tank rib 44b is moved, it functions as a resistance.

  Hereinafter, how the tank 40 is inserted into the insertion space S of the main casing 10 will be described.

(Insertion of tank)
As shown in FIG. 1, since the tank 40 is detachably provided in the insertion space S of the main body casing 10, the tank 40 is inserted by grasping the tank handle 48 of the drawer-type tank extraction surface 47. Thus, it can be inserted into the insertion space S through the tank outlet 12 of the main body casing 10.

  Here, FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17 are cross-sectional views showing the positional relationship between the tank 40 and the main body casing 10, which are cross-sectional views as viewed from above the humidity control air cleaning device 1. And in FIG.

  Moreover, front sectional views showing the positional relationship between the tank 40 and the main body casing 10, which are sectional views seen from the front side of the humidity control air cleaning device 1, are shown in FIGS. 19, 20, 21, and 22, respectively. .

  16 corresponds to the front state of FIG. 19, the planar state shown in FIG. 17 corresponds to the front state of FIG. 20, and the planar state shown in FIG. 18 corresponds to the front state of FIG. ing.

  First, the user grasps the tank handle 48 and moves the position of the tank 40 so that the tank insertion surface 40 s of the tank 40 is positioned within the frame of the tank outlet 12 of the main body casing 10.

  Here, as shown in FIG. 13, the front surface of the tank front surface 40f is not positioned on the inner side of the rear surface surface of the main body front surface 10f, and is shifted by a distance h1 and is in contact with the point Q1. May be inserted in the direction indicated by.

  Here, as shown in FIG. 13 and the like, the main body casing 10 is configured by the main body bottom surface 15 rather than the position of the edge formed by the main body front surface 10f and the main body rear surface 10b among the edges of the tank outlet 12. The edge is formed so as to be recessed toward the insertion side by a predetermined recess distance h2. On the other hand, as shown in FIG. 13, from the end opposite to the insertion side of the front tank curved surface 45f and the back tank curved surface 45b described above, the insertion side end of the front tank rib 44f and the rear tank rib 44b on the back side. The predetermined thickness h <b> 3 until is shorter than the predetermined recess distance h <b> 2 that is the recess of the main body casing 10.

  For this reason, when the tank 40 is inserted, the front tank rib 44f and the rear tank rib 44b reach the portion of the main body bottom surface 15 that is depressed by a predetermined depression distance h2, and the vertical position of the main body bottom surface 15 is guided. The front tank curved surface 45f or the rear tank curved surface 45b abuts against the edge formed by the main body front surface 10f or the main body back surface 10b among the edges of the tank outlet 12 of the main body casing 10, before the tank 40 is First, the position in the left-right direction is guided. Therefore, when the tank 40 is inserted, first, the guide of the position in the left-right direction with respect to the tank outlet 12 of the tank 40 (correction of the deviation between the front side and the back side) is performed, and then the guide in the vertical direction ( Are inserted in the order of correction in the height direction).

  In this case, as shown in FIG. 14, even when the position of the left and right end portions of the tank 40 is inserted from a position that does not correspond to the left and right widths of the tank outlet 12 of the main body casing 10. Thus, since the front tank curved surface 45f has a curved shape, the tank 40 easily moves in the direction of the arrow shown in FIG. 14 even when the user applies a force in the direction of the arrow in FIG. For this reason, the insertion side front end of the tank front surface 40f is in contact with the point Q2 so as to be located inside the main body front surface 10f. Therefore, as shown in FIG. 15, the tank 40 can be inserted so as to rotate with the point Q3 as a fulcrum, and the tank insertion surface 40s can be accommodated in the frame of the tank outlet 12 of the main body casing 10. It is guided to the correct position without making the user aware of the special insertion direction. The adjustment of the position of the tank 40 in the horizontal direction is the same even when the back tank curved surface 45b first contacts the main body back surface 10b.

  The user further inserts the tank 40 into the insertion space S in a state where the tank insertion surface 40 s is housed in the frame of the tank outlet 12 of the main body casing 10.

  Then, as shown in FIG. 16, at least one of the contact portions X of the front tank rib 44f and the rear tank rib 44b (both may be simultaneously) is located at the end of the main body bottom surface 15 on the tank outlet 12 side at the point P1. It comes into contact. As described above, this state has a positional relationship as shown in FIG. Here, the upper surface of the bottom opening side edge 15p described above has a height (h5) raised by the height of the casters 19 provided at the four corners of the main body bottom surface 15 and the shape of the main body bottom surface 15 and the bottom surface opening. Depending on the thickness and height (h4) of the side edge 15p itself, it is located vertically above the floor G by h4 + h5 (because the caster 19 exists in the depth direction or the front direction in FIG. 19). (Shown as a dotted line). For this reason, the front tank rib 44f and the rear tank rib 44b that are in contact with the floor G are partially in contact with the bottom opening side edge 15p at a point away from the floor G indicated by a point P1 in FIG. ing.

  Here, the front tank rib 44f and the back tank rib 44b of the tank 40 are provided with contact portions X whose edges are located higher from the lower end toward the insertion side. The heights of the front tank rib 44f and the back tank rib 44b provided in the tank 40 extend at least longer than the thickness (h4) of the main body bottom surface 15 in the vicinity of the tank outlet 12. Specifically, here, the front tank rib 44f and the back tank rib 44b are inserted in the middle of the insertion side edge from the lower end of the front tank rib 44f and the back tank rib 44b to a height exceeding the height of h4 + h5. Without having a portion that is not inclined to the side, it is gently formed so as to rise upward from the lower end toward the insertion direction.

  For this reason, when the tank 40 is slid with respect to the floor G so that the tank 40 advances toward the insertion side and is inserted into the insertion space S of the main casing 10 through the tank outlet 12, the insertion becomes easy. That is, the insertion of the tank 40 is not obstructed by the thickness of the bottom surface 15 of the main body, and the contact portion X of the front tank rib 44f and the rear tank rib 44b of the tank 40 constitutes the lower edge of the tank outlet 12 (the tank bottom surface 15 is constituted. The bottom side opening side end portion 15p in the vicinity of the upper end of the bottom surface opening side is easily slid while the increase in insertion resistance is suppressed on the upper side of the bottom surface 15 of the main body.

  As described above, the curved inclined portions of the front tank rib 44f and the back tank rib 44b extend to a portion beyond the height position of the upper surface of the bottom surface opening side edge 15p, so that the user can further insert the tank 40 into the space S. When a light force is applied in the insertion direction, the curved inclined portions of the front tank rib 44f and the back tank rib 44b slide sequentially at the contact point P2 with the bottom opening side edge 15p as shown in FIG. The tank insertion surface 40s side of the tank 40 moves upward in the vertical direction while moving in the insertion direction. This state is the state shown in the plan sectional view of FIG.

  When the user further pushes the tank 40 into the insertion space S, as shown in FIG. 21, the front tank rib 44f and the back tank rib 44b are completely raised to the upper surface side of the main body bottom surface 15, and a plan sectional view is shown in FIG. Due to the positional relationship, the tank 40 can be easily inserted into the insertion space S.

(Tank extraction)
As shown in FIG. 1, the tank 40 is detachably provided in the insertion space S of the main body casing 10, so that the tank 40 is pulled out by grasping the tank handle 48 of the drawer-type tank extraction surface 47. Thus, the tank 40 can be extracted from the tank outlet 12 of the main body casing 10.

  Here, as shown in FIG. 22, when the entire tank 40 is in a state immediately before being extracted from the tank outlet 12, a bottom surface recess 15 d is provided in the vicinity of the bottom opening side edge 15 p on the main body bottom surface 15. Therefore, the end portions in the extraction direction of the front tank rib 44f and the back tank rib 44b come into contact with the wall surface in the extraction direction of the bottom recess 15d, and the resistance to extraction increases at a stretch.

  That is, since the end of the front tank rib 44f or the back side tank rib 44b opposite to the insertion side is located in the vicinity of the insertion side end of the tank 40, the upper surface of the main body bottom surface 15 near the tank outlet 12 The bottom recess 15d provided on the side faces the opposite side of the insertion side in contact with the front tank rib 44f and the rear tank rib 44b on the rear side when the entire tank 40 is removed from the main body casing 10. When the front tank rib 44f or the rear tank rib 44b on the back side is moved, it functions as a resistor.

  Thereby, when the tank 40 is pulled out, the front tank rib 44f and the rear tank rib 44b on the rear side are removed from the bottom recess 15d of the main body bottom surface 15 while the tank 40 is almost entirely removed from the main body casing 10. Start receiving resistance. For this reason, before the tank 40 is taken out from the main body casing 10 and dropped from the bottom surface 15 of the main body, it is possible to make a user grasp the state of the tank 40. Therefore, even when the user pulls out the tank 40 from the insertion space S vigorously, the load is temporarily increased before the tank 40 is completely extracted, so that the tank 40 is completely extracted. You can see that you are in the foreground. Thereby, the tank 40 can be prevented from falling off, so that the tank 40 can be prevented from being damaged due to the tank 40 coming off from the bottom surface 15 of the main body.

  As a result, when the user pulls out the tank 40 vigorously, the vicinity of the lower end of the tank insertion surface 40s of the tank 40, the front tank rib 44f and the rear tank rib 44b are vigorously struck against the floor G and are broken. is made of.

  Further, the state in which the load temporarily increases before the tank 40 is completely extracted as shown in FIG. 22 is equal to the positional relationship when the tank 40 is to be extracted in the state shown in FIG. In a state in which almost the whole is taken out from the insertion space S, the appendage portion 40w constituting a part of the tank front surface 40f of the tank 40 has moved to a position where it is exposed to the outside of the main body casing 10. And since this attachment part 40w has the shape hollow in the back side in the insertion side edge part vicinity of the tank front 40f, the state which has grasped the tank handle 48 with the right hand and extracted the tank 40 from the insertion space S Then, the user can lift the tank 40 with both hands by inserting the surplus left hand into the appendage 40w and supporting the tank 40 from below. Thus, when the tank 40 is extracted, the timing for attaching the left hand to the attachment portion 40w of the tank 40 and lifting it with both hands is determined by the user once the load increases before the tank 40 is completely extracted. I can grasp it. For this reason, the user can attach his left hand in a state where the load is once increased before the tank 40 is detached from the main body casing 10.

  In this manner, the user can take out the tank 40 from the main body casing 10, replenish water for humidification, discard water during dehumidification, and wash the water wheel 42.

  Hereinafter, the drain pan 50 in which the inclination state is changed by the insertion and extraction of the tank 40 described above will be described.

<Drain pan condition during tank insertion and removal>
(Detailed configuration of drain pan)
FIG. 23 is a perspective view showing the drain pan and its surrounding arrangement in a state where the tank is inserted, and FIG. 24 is a perspective view showing the drain pan and its neighboring arrangement in a state where the tank is being extracted. , Respectively.

  FIG. 25 shows a rear view showing the inclined state of the drain pan when the tank is inserted, and FIG. 26 shows a rear view showing the inclined state of the drain pan when the tank is being extracted.

  Here, as shown in FIGS. 23, 24, 25, and 26, the drain pan 50 includes a swing shaft 51, a spout 52, a spare container 53, a humidified water receiver 54, and an inclined rib 55. It has.

  The swing shaft 51 is an axis extending from the front side toward the back side. The swing shaft 51 supports the drain pan 50 with respect to the lower end portion of the dehumidifying unit 3 so as to be rotatable about the shaft.

  The spout 52 is an opening penetrating in the vertical direction in order to guide the water replenished in the drain pan 50 to the tank 40 disposed below, and is provided in the vicinity of the swing shaft 51. As a result, as shown in FIGS. 24 and 25, when the inclined state of the drain pan 50 is a substantially horizontal state, the replenished water flows down toward the tank 40.

  The spare container 53 constitutes a water receiver on the left side in the front view of the drain pan 50, that is, the insertion side of the tank 40, and mainly supplements condensed water generated in the dehumidifying unit 3. Here, as shown in FIG. 26, the dehumidifying unit 3 can drop the condensed water generated in the heat exchanging unit 35 onto the preliminary container 53 through the drain port 38 provided at the lower end of the dehumidifying unit 3. it can.

  The humidifying water receiver 54 constitutes a water receiver on the opposite side of the swing container 51 with respect to the above-described spare container 53 among the water receivers of the drain pan 50, and mainly in the humidifying unit 4. On the other hand, when the water turbine 42 supplies water, the vaporizing element 41 cannot hold and replenishes water to be dropped.

  The inclined rib 55 is a rib that protrudes further downward from the left side of the front view, that is, the lower surface on the insertion side of the tank 40, and is formed so that the degree of protrusion increases as it goes in the insertion direction.

  With the above configuration, the drain pan 50 is heavier and heavier on the side on which the preliminary container 53 and the inclined rib 55 are provided than on the side on which the humidified water receiver 54 is provided with respect to the swing shaft 51. . The swing shaft 51 is disposed closer to the humidified water receiver 54 than the center of gravity of the drain pan 50. For this reason, in a state where no force is applied to the drain pan 50, the drain pan 50 moves downward on the side where the preliminary container 53 and the inclined rib 55 are provided, and is lifted on the side where the humidified water receiver 54 is provided. In this way, the balance is maintained.

(Inclined drain pan)
(When the tank is inserted)
In a state where the tank 40 is inserted into the insertion space S, as shown in FIG. 25, the upper surface portion of the tank 40 is lifted in contact with the inclined rib 55 of the drain pan 50 at the point T, and the drain pan 50 lifts the swing shaft 51. It rotates as an axis and the inclined state of the drain pan 50 becomes a substantially horizontal state. For this reason, in a state where the tank 40 is inserted, the drain pan 50 guides the replenishing water from the dehumidifying unit 3 and the humidifying unit 4 to the tank 40 existing below through the spout 52.

(When removing the tank)
In a state where the tank 40 is extracted from the insertion space S to the extent that it does not touch the inclined rib 55, the upper surface portion of the tank 40 is not in contact with the inclined rib 55 of the drain pan 50 at the point U as shown in FIG. Therefore, the drain pan 50 is rotated about the swing shaft 51 as the axis, and the drain pan 50 is inclined when the side on which the preliminary container 53 and the inclined rib 55 are provided moves downward and the humidified water receiver 54 is provided. It is in a tilted state in which the balance is maintained by lifting the side that is on.

  Thereby, even if the tank 4 becomes full due to the condensed water from the dehumidifying unit 3 and the tank 40 is extracted and the drainage operation is performed, even if the tank 40 is absent under the dehumidifying unit 3, Condensed water falling from the heat exchanging section 35 and the like of the dehumidifying unit 3 can function as a water receiver with the auxiliary container 53 inclined, so that the water in the tank 40 is drained and the tank 40 is mounted again. Temporary rehydration can be performed. Further, since the humidifying water receiver 54 of the drain pan 50 is provided to extend vertically below the vaporizing element 41 of the humidifying unit 4, the vaporizing element 41 even when the tank 40 is extracted from the main body casing 10. Water can be replenished. Thereby, even if the tank 40 is extracted, it is possible to prevent the condensed water from the dehumidifying unit 3 and the water falling from the vaporizing element 41 from dropping on the main body bottom surface 15 of the main body casing 1. When the tank 40 is inserted again, after the tank 40 is in the state of being present under the spout 52 of the drain pan 50, the water stored in the spare container 53 comes into contact with the inclined rib 55. Guide to tank 40. For this reason, the water leakage accompanying the insertion operation of the tank 40 can also be prevented.

<Characteristics of the humidity control air cleaning device 1 according to the present embodiment>
(1)
In a conventional dehumidifier or humidifier, when a tank is set on the main body, it is necessary to lift the tank from the floor so that the front end of the tank matches the opening position of the main body. In addition, there are wheels on the tank that assist in insertion, but even in that case, when inserting, the end of the tank must be lifted so that the tip of the tank matches the opening position of the main body, A separate member called a wheel is required.

  On the other hand, in the humidity control air purification apparatus 1 which concerns on this embodiment, it has the structure which carries the water of the tank 40 to the vaporization element 41 located above the tank 40 with the water wheel 42 which functions as a water supply means. Therefore, in the configuration in which the water of the tank 40 is transported upward as described above, the tank 40 needs to be disposed below the main body casing 10, particularly below the vaporizing element 41. Therefore, in this embodiment, the tank 40 is inserted into the main body casing 10 through the tank outlet 12 provided below the main body casing 10 while sliding the tank 40 in the insertion space S in a substantially horizontal direction. To be done.

  In the present embodiment, the front tank rib 44f and the back tank rib 44b of the tank 40 are provided with contact portions X formed so as to rise upward in the insertion direction. Further, the front tank rib 44f and the back tank rib 44b are arranged such that the insertion side edge between the lower end of the front tank rib 44f and the back tank rib 44b and the height exceeding the height of h4 + h5 is upward from the lower end toward the insertion direction. It is formed to rise. Furthermore, the edge on the insertion side has a shape that is gently inclined without having a portion that is not inclined on the insertion side while going upward from the lower end.

  Therefore, the insertion of the tank 40 is not blocked by the thickness of the main body bottom surface 15, and the contact portion X between the front tank rib 44 f and the rear tank rib 44 b of the tank 40 constitutes the tank bottom surface 15 among the edges of the tank outlet 12. The insertion side of the tank 40 is slid up easily on the upper surface side of the bottom surface 15 of the main body while suppressing an increase in insertion resistance so as to slide in the vicinity of the upper end of the bottom opening side end portion 15p. In particular, the contact portion X in the vicinity of the height position of the upper surface of the main body bottom surface 15 (height of h4 + h5) is formed so as to rise upward as it goes in the insertion direction. be able to.

  Thus, the simple configuration in which the front tank rib 44f and the rear tank rib 44b are provided in the tank 40 can facilitate the insertion into the main body casing 10.

(2)
In the humidity control air cleaning device 1 according to the present embodiment, the edge on the insertion side from the lower end of the front tank rib 44f and the rear tank rib 44b to the height exceeding the upper surface height of the main body bottom surface 15 is upward from the lower end. It is formed so as to be positioned closer to the insertion side as it goes up. For this reason, an increase in insertion resistance when the tank 40 is inserted can be suppressed, and the tank 40 can be smoothly inserted into the main body casing 10.

(3)
In the humidity control air cleaning device 1 according to the present embodiment, the lower surface of the tank bottom surface 46 supported by the tank rib 44 is lower than the upper surface of the main body bottom surface 15 in a state where the tank 40 and the main body casing 10 are placed on the floor surface G. Even if it exists in a position, the insertion load of the tank 40 can be reduced.

(4)
In the humidity control air cleaning device 1 according to the present embodiment, the front tank curved surface 45f and the back tank curved surface 45b allow the vicinity of the insertion side end of the tank 40 to be substantially perpendicular to the insertion side as it goes to the insertion side. Since the width of the horizontal component becomes narrower, the horizontal component can be easily guided into the tank outlet 12 in the horizontal direction, and the insertion work becomes easier.

(5)
The size of the tank 40 in the vertical and horizontal directions is already determined when it is molded. The space inside the tank outlet 12 in the main body casing 10 is also molded and shaped to have a size corresponding to the shape, size, etc. of the tank 40.

  In such a case, as a method of guiding the tank 40 so that it can be inserted into the tank outlet 12, after guiding the vertical component to the desired component (height) first, the horizontal component is desired. To guide the component (left and right position), the guide is performed until the front end of the tank 40 is placed on the upper surface of the main body bottom surface 15 of the main body casing 10, and then the right and left direction component is adjusted from that state. become. For this reason, it is necessary to provide an extra size in the left-right direction of the tank outlet 12.

  On the other hand, in the humidity control air cleaning apparatus 1 according to the present embodiment, the main body casing 10 is located at the edge of the tank outlet 12 from the position of the edge constituted by the main body front face 10f and the main body rear face 10b. The edge formed by the main body bottom surface 15 is formed so as to be recessed toward the insertion side by a predetermined depression distance h2, and from the end opposite to the insertion side of the front tank curved surface 45f and the back tank curved surface 45b described above, The predetermined thickness h3 between the front tank rib 44f and the back side tank rib 44b on the insertion side is formed to be shorter than the predetermined depression distance h2 that is a depression of the main body casing 10.

  For this reason, when the tank 40 is inserted, the front tank rib 44f and the rear tank rib 44b on the rear side reach the recessed portion of the main body bottom surface 15 (the end portion on the tank outlet 12 side) and the vertical position of the main body bottom surface 15 is reached. Prior to the guiding, the front tank curved surface 45f and the back tank curved surface 45b abut against the edges of the main body front surface 10f and the main body back surface 10b among the edges of the tank outlet 12 of the main body casing 10, and the tank 40 The direction position is guided and guided to the inside of the width of the tank outlet 12 in the left-right direction. Then, the front tank rib 44f of the tank 40 and the rear tank rib 44b on the rear side are slid up on the recessed portion (near the end of the tank outlet 12 side) of the main body bottom 15 with the position in the left-right direction fixed. The position in the vertical direction is guided and guided to the inside of the tank outlet 12 also in the vertical direction. Thus, the tank 40 can be easily guided to the insertion position.

  In addition, about the up-down direction, the position of a lower end is decided in the state contact | abutted with the floor G by gravity. At the time of molding, the upper end is also determined by the size of the tank 40 in the vertical direction. For this reason, since the lower end and the upper end are determined in advance, the tank outlet 12 of the main body casing 10 does not need to have an extra vertical width.

(6)
In the humidity control air purifying apparatus 1 according to the present embodiment, the end of the front tank rib 44f and the back tank rib 44b on the opposite side to the insertion side is located near the insertion side end of the tank 40, and The bottom recess 15 d is provided in the vicinity of the tank outlet 12 on the upper surface side of the bottom surface 15 of the main body.

  For this reason, when almost the entire tank 40 is removed from the main body casing 10, the front tank rib 44f and the rear side face toward the opposite side of the insertion side in contact with the front tank rib 44f and the rear tank rib 44b on the rear side. When the rear tank rib 44b is moved, the bottom recess 15d can function as a resistance against the extraction of the tank 40.

  Further, the end of the front tank rib 44f and the back side tank rib 44b opposite to the insertion side is located in the vicinity of the insertion side end of the tank 40, and the bottom surface recess 15d is the top surface of the main body bottom surface 15. Since it is provided in the vicinity of the tank outlet 12 on the side, it is possible to start receiving resistance to extraction in a state where almost the entire tank 40 is being removed from the main body casing 10. Therefore, before the tank 40 is taken out from the main body casing 10 and dropped from the main body bottom surface 15, it is possible to make the user who wants to extract the tank 40 know the state. Thereby, the tank 40 can be prevented from falling off, so that the tank 40 can be prevented from being damaged due to the tank 40 coming off from the bottom surface 15 of the main body. Further, water splash due to the drop off of the tank 40 can be prevented.

(7)
In the humidity control air cleaning device 1 according to the present embodiment, the air cleaning unit 5, the dehumidifying unit 3, the humidifying unit 4, and the blower 2 are arranged in this order. When the blower 2 is operated, an air flow path A in which air flows from the air cleaning unit 5 toward the blower 2 is formed. Since the dehumidifying operation and the humidifying operation are switched without switching the direction of the air flow path, the flow path structure is simple, and the size can be reduced particularly in the front-rear direction.

  And since it is arranged in order of the air purifying area, the dehumidifying area, and the humidifying area from the upstream with respect to the air flow path A, the moisture remaining in the humidifying unit 4 is changed when the humidifying operation is switched to the dehumidifying operation. While receiving in the tank 40, the dehumidified air dries the moisture remaining in the humidifying unit 4, so that generation of mold and off-flavor is prevented.

(8)
In the humidity control air cleaning apparatus 1 according to the present embodiment, the water generated by dehumidification is stored in the tank 40, so that the tank 40 is automatically replenished with water, and the sustainable time of the humidifying operation is extended. As a result, the necessary number of insertion and removal operations of the tank 40 can be reduced.

(9)
In the humidity control air cleaning device 1 according to the present embodiment, the water wheel 42 of the humidifying unit 4 has a rotation axis parallel to the rotation axes of the adsorption element 31 and the vaporization element 41, and between the adsorption element 31 and the vaporization element 41. Is arranged. The adsorption element 31 is housed in the flat area 3 a of the dehumidifying unit 3, and the vaporizing element 41 is housed in the flat area 4 a of the humidifying unit 4. The heat exchanging unit 35 of the dehumidifying unit 3 is also housed in the flat region 3a of the dehumidifying unit 3 and arranged so as to surround the outer periphery of the adsorption element. For this reason, the increase in the dimension in the thickness direction is suppressed. Thereby, the tank 40 inserted in the main body casing 10 can receive water falling from any region.

<Modification of Humidity Controlling Air Cleaning Device 1>
As mentioned above, although embodiment of this invention was described based on drawing, a specific structure is not restricted to these embodiment, It can change in the range which does not deviate from the summary of invention.

(A)
In the above embodiment, the case where the caster 19 is provided on the main body bottom surface 15 of the main body casing 10 has been described as an example.

  However, the present invention is not limited to this, and in particular, the caster 19 does not need to be provided on the main body casing 10 side, and is simply formed so as not to move with respect to the floor G. Also good.

  Further, when the caster 19 is not provided and the main body bottom surface 15 of the main body casing 10 is in direct contact with the floor surface G, the front tank rib 44f provided on the tank 40 or the rear tank rib 44b on the rear side. If the height is provided to a height exceeding the height of the upper surface of the main body bottom surface 15 in the vicinity of the tank outlet 12, the same effect as in the above embodiment can be obtained.

(B)
In the above embodiment, the position of the edge constituted by the main body bottom surface 15 out of the edge of the tank outlet 12 is the predetermined depression distance h2 than the position of the edge constituted by the main body front face 10f and the main body rear face 10b. It is formed so as to be recessed only on the insertion side, and a predetermined distance from an end portion on the opposite side to the insertion side of the front tank curved surface 45f and the rear tank curved surface 45b to an insertion side end portion of the front tank rib 44f and the rear tank rib 44b on the rear side. The case where the thickness h3 is formed to be shorter than the predetermined recess distance h2 that is the recess of the main body casing 10 has been described as an example.

  However, the present invention is not limited to this. For example, as shown in FIG. 29, the main body casing 10 does not have such a recess in the main body bottom surface 15, and the opening of the tank outlet 12 is formed on the floor surface G. The tank 40 has a front tank rib 44f on the side opposite to the insertion side of the front tank curved surface 45f and the rear tank curved surface 45b on the side opposite to the insertion side. Alternatively, a back tank rib 44b on the back side may be provided. For example, the front tank rib 44 f and the rear tank rib 44 b on the back side may be provided near the approximate center of the tank bottom surface 46 of the tank 40.

  And like the said embodiment, the magnitude | sizes, such as an up-down and left-right direction, of the tank 40 are already decided at the time of shaping | molding. The space inside the tank outlet 12 in the main body casing 10 is also molded and shaped to have a size corresponding to the shape, size, etc. of the tank 40. In such a case, as a method of guiding the tank 40 so that it can be inserted into the tank outlet 12, after guiding the vertical component to the desired component (height) first, the horizontal component is desired. To guide the component (left and right position), the guide is performed until the front end of the tank 40 is placed on the upper surface of the main body bottom surface 15 of the main body casing 10, and then the right and left direction component is adjusted from that state. become. For this reason, it is necessary to provide an extra size in the left-right direction of the tank outlet 12.

  On the other hand, in the present modification (B), the tank outlet 12 has a quadrangular shape that is substantially perpendicular to the floor surface G, and the front tank curved surface 45f and the back tank curved surface 45b are front tank ribs 44f. And the rear tank rib 44b on the rear side is located on the insertion side (for example, the front tank rib 44f and the rear tank rib 44b on the rear side extend downward from the vicinity of the center of the lower surface of the tank bottom 46). 40 is inserted before the front tank rib 44f and the rear tank rib 44b on the back side abut on the vicinity of the tank outlet 12 on the bottom surface 15 of the main body and the vertical position guide is performed. The tank back surface 45b comes into contact with the edge of the main body front face 10f and the main body rear face 10b among the edges of the tank outlet 12 so that the tank 40 is first positioned in the left-right direction. Is guided to the inner width of the tank outlet 12 for the left and right directions are de.

  Then, in a state where the position of the tank 40 in the left-right direction is fixed, the front tank rib 44f of the tank 40 and the rear tank rib 44b on the back side slide up with respect to the vicinity of the tank outlet 12 of the main body bottom surface 15 so that the vertical position Is guided to the inside of the tank outlet 12 also in the vertical direction. Therefore, the tank can be easily guided to the insertion position.

  Here, in the vertical direction of the tank 40, the lower end is determined in advance by gravity and the upper end is determined in advance by the shape of the tank 40, so the tank outlet 12 of the main body casing 10 needs to have an extra vertical width. There is no.

(C)
In the above-described embodiment, the tank rib 44 has been described as an example having a shape that is provided in the vicinity of the lower end portion on the insertion side of the tank 40 and whose edge draws a curve with a predetermined radius of curvature.

  However, the present invention is not limited to this. For example, the tank rib is provided so as to extend downward from the lower surface of the tank bottom surface 46, has a shape without a curve, and has an edge on the insertion side of the tank rib and the tank rib. It is good also as a shape where the angle which the lower surface of the tank bottom face 46 of the insertion side of the extension part makes is an obtuse angle. Even in this case, the insertion burden can be similarly reduced.

(D)
In the above embodiment, the case where the dehumidifying region is located upstream of the humidifying region with respect to the air flow path A has been described as an example.

  However, the present invention is not limited to this, and for example, the dehumidifying region may be located downstream of the humidifying region. Thereby, even when the air passing through the humidifying unit 4 absorbs moisture remaining in the humidifying unit 4 when the humidifying operation is switched to the dehumidifying operation, the air passes through the dehumidifying unit 3 reliably. Dehumidified air can be released.

  Further, the humidification area and the dehumidification area may be positioned in parallel. As a result, the dehumidifying operation and the humidifying operation can be performed at the same time. For example, while controlling the indoor humidity with the humidified air, the dehumidified air is blown out to the indoor glass window side to prevent the condensation of the glass. it can.

(E)
In the said embodiment, as shown in FIG. 13, the case where the part bordered by the main body bottom face 15 among the edges of the tank outlet 12 was formed in the whole was demonstrated as an example.

  However, the present invention is not limited to this. For example, as shown in FIG. 30, only the locus portion through which the tank rib 44 of the tank 40 passes may be recessed.

  If the present invention is used, it is possible to easily insert the tank into the main body with a simple configuration. Therefore, the present invention is particularly useful in a humidity control apparatus that is used by inserting and removing the tank in the substantially horizontal direction. .
