<Dehumidification unit>
FIG. 5 is a perspective view of the dehumidifying unit, and FIG. 6 is a front view of the dehumidifying unit viewed from the back side. 5 and 6, the dehumidifying unit 3 includes an adsorption element 31, a heater 32, a second blower 33, a blower pipe 34, and a heat exchange unit 35. 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 is selected from thermoplastic resins such as modified PPE, polypropylene, polystyrene, and ABS resin, for example. 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 flow. By operating the second blower 33, an air flow is formed, and the air flows along the direction indicated by the arrow in FIG. 5 in the first blower pipe 34a. And the air which flowed to the heater 32 vicinity is heated there and turns into 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. 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 to the front side contains moisture released from the adsorbing element 31, becomes high-temperature and high-humidity air, and proceeds to the second blower pipe 34 b. 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 thickness 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 long hole 35a exchanges heat with the high-temperature and high-humidity air flowing through the third blower pipe 34c, and the heat quantity from the air flowing through the third blower pipe 34c is not mixed with each other. Take away. 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 in the third blower pipe 34c and flows into the tank 40 through the drain pan 50 through the drain port 38 (see FIG. 6) penetrating in the vertical direction.

  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 unit 35 are included in the flat region 3a.

  In FIG. 6, 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, power is transmitted to the driven gear 311 meshing with the pinion gear 361, and the adsorption element 31 rotates. When the adsorption element 31 is rotating, the air sucked into the main body casing 10 passes through the air flow path A, so that the air passes through a part of the adsorption element 31. When this air passes through the adsorbing element 31, the adsorbing element 31 adsorbs and holds moisture contained in the air to be passed, and reduces the moisture of 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, an operation 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 operation panel 11 that receives the selection input is connected to the control unit 6 so as to be communicable. The operation panel 11 includes a selection button 37 that can select the rotation and stop of the adsorption element 31. When the selection button is switched to the OFF state during the dehumidifying operation, the rotation of the adsorption element 31 is stopped and positively performed. Dehumidification 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 is warmed and blown off when passing the heat exchange part 35, 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 operation panel 11.

<Humidification unit>
FIG. 7 is a perspective view of the humidifying unit. In FIG. 7, the humidifying unit 4 is provided on the back side of the dehumidifying unit 3 inside the main body casing 10, and includes a vaporizing element 41, a water wheel 42, and a drive unit 43. The humidification unit 4 performs humidification using the water stored in the tank 40. The tank 40 is detachably accommodated in the insertion space S of the main body casing 10. When the water in the tank 40 is insufficient, in order to replenish the water for humidification, the user pulls out the tank 40 from the tank outlet 12 (see FIG. 1) of the main body casing 10 and replenishes the water. I do. In addition, since the humidity control air cleaning apparatus 1 of this embodiment stores the water captured by operating the dehumidification unit 3 in the tank 40, and the humidification unit 4 can utilize the water, it is only humidification. Compared with the conventional humidifier which performs, water replenishment frequency can be reduced.

  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 rotates when the drive unit 43 drives the drive 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.

  A water amount sensor 144 is provided in the tank 40 (see FIG. 1). The water amount sensor 144 is a sensor that detects the amount of water in the tank 40, and is provided to prevent a drought state of the tank 40. The water amount sensor 144 can be replaced with a float switch.

  FIG. 8 is a perspective view of the humidification unit and the tank as seen from the back side. In FIG. 8, the water wheel 42 is rotatably supported by a bearing 40 a provided in the tank 40. The water turbine 42 rotates to catch water in the tank 40 at a portion located below the water surface in the tank 40, pumps up to a portion on the water surface facing the vaporizing element 41, and pumps the pumped water up to the water wheel. Water is supplied to the vaporizing element 41 so as to be released from the vaporizing element 42.

  As a structural consideration, in order to reduce the dimension in the thickness direction of the humidifying unit 4 and make the thickness of the humidity control air cleaning device 1 itself compact, the vaporizing element 41 and the water turbine 42 have substantially the same axis of rotation. They are in a parallel positional relationship and are arranged adjacent to each other.

  The water wheel 42 is formed so as to be recessed in the axial direction in the vicinity of the outer periphery on the back side of the water wheel 42 in order to carry the water of the tank 40 to the vaporizing element 41 positioned further upward while rotating about the shaft. A plurality of substantially trapezoidal concave portions 421a are provided.

  FIG. 9 is an exploded perspective view of the water wheel. In FIG. 9, 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 at positions where the plurality of recesses 421a of the wheel 421 face 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 a state where the wheel 421 and the wheel cover 422 are combined, a receiving groove is formed between the wheel 421 and the wheel cover 422 so as to be recessed in the vertical direction at a predetermined rotational position. It is possible to pump up.

  The second gear 423 is a gear that meshes with the first gear 411 (see FIG. 8) of the vaporizing element 41, and a rotation shaft 424 shared by the wheel 421, the wheel cover 422, and the second gear 423 is provided at the center of rotation. It has been. 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. When the recess 421a is submerged, water flows into the recess 421a through the hole 422a, and the receiving groove between the wheel 421 and the wheel cover 422 exits from the water in a state where the interior is filled with water.

  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 water flows out, the water flows out so as to reach the front side of the vaporizing element 41 adjacent to the recess 421a.

  As shown in FIG. 8, the rotation shaft 424 is rotatably supported by the bearing 40 a of the tank 40. The height from the inner bottom surface of the tank 40 to the shaft core of the bearing 40a is such that the recess 421a at the lowest position of the water turbine 42 is submerged even when the water turbine 42 is disposed when the tank 40 is at the lowest water level. It is set to be the height to be.

  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. 10 is a perspective view of a state where the dehumidifying unit and the humidifying unit are combined. In FIG. 10, the humidifying unit 4 is arranged below the second blower 33 of the dehumidifying unit 3 so as to overlap along the air flow direction. The vaporizing element 41 of the humidifying unit 4 faces the adsorbing element 31 and the heat exchange unit 35 (see FIG. 6) of the dehumidifying unit 3. The water turbine 42 is disposed so as to be sandwiched between the vaporizing element 41 and the heat exchange unit 35.

<Attachment / removal mechanism of vaporization element>
As shown in FIGS. 7 and 8, the vaporizing element 41 is formed in a shape that does not project the rotating shaft in order to facilitate removal from the main body casing 10. The vaporizing element 41 is supported by the drive gear 431 and the second gear 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.

  Similarly, when the vaporizing element 41 is housed in the main body casing 10, since there is no protruding shaft, the vaporizing element 41 is easily housed without being caught inside the main body casing 10. When the vaporizing element 41 is stored in the main body casing 10, the limit switch installed on the back side of the tank outlet 12 is turned on, so that the control unit 6 confirms the presence or absence of the vaporizing element 41 by this on signal. can do.

  As shown in FIG. 1, in the main body casing 10, the outlet 13 is exposed by opening the rotary door 16. Thereby, the vaporizing element 41 can be taken out via the outlet 13 by opening the door 16. As a result, the user can take out the vaporizing element 41 and replace it.

FIG. FIG. 13 is a rear view showing the inclined state of the drain pan when the tank is inserted into the insertion space, and FIG. 14 shows the inclined state of the drain pan when the tank is being extracted from the insertion space. It is a rear view.

  11, 12, 13, and 14, the drain pan 50 includes a swing shaft 51, a spout 52, a preliminary container 53, a humidified water receiver 54, and an inclined rib 55. The swing shaft 51 is an axis extending from the front side toward the back side. The swing shaft 51 rotatably supports the drain pan 50.

  The spout 52 penetrates in the vertical direction in order to guide the water captured in the drain pan 50 to the tank 40 disposed below. The preliminary container 53 captures the condensed water generated in the dehumidifying unit 3. As shown in FIG. 14, the dehumidifying unit 3 can drop the condensed water generated in the heat exchanging unit 35 on the preliminary container 53 via the drain port 38 provided at the lower end of the dehumidifying unit 3. The humidified water receiver 54 captures water that the vaporizing element 41 cannot hold and drops when the water wheel 42 supplies water. The inclined rib 55 is a rib that protrudes further downward from the lower surface of the tank 40 on the insertion side, and is formed so that the degree of protrusion increases as it goes in the insertion direction.

  The drain pan 50 is larger and heavier on the side where the auxiliary container 53 and the inclined rib 55 are provided than on the side where 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. .

(When the tank is inserted)
In the state where the tank 40 is inserted into the insertion space S, as shown in FIG. 13, at the point T, the upper surface portion of the tank 40 abuts against the inclined rib 55 of the drain pan 50 and lifts, and the drain pan 50 moves the swing shaft 51. It rotates as an axis and the inclined state of the drain pan 50 becomes a substantially horizontal state. As a result, in a state where the tank 40 is inserted, the drain pan 50 guides the water captured 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 so as not to 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. For this reason, the drain pan 50 rotates about the swing shaft 51, and the drain pan 50 is tilted 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. The side is lifted.

  For example, when the tank 40 is full due to the condensed water from the dehumidifying unit 3 and the user pulls out the tank 40 and performs the drainage operation, the tank 40 is absent under the dehumidifying unit 3, but the heat exchange of the dehumidifying unit 3 is performed. Condensed water falling from the part 35 and the like can trap water temporarily until the water in the tank 40 is drained and the tank 40 is mounted again because the auxiliary container 53 is inclined and functions as a water receiver. it can. 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. Can capture the falling water from. Therefore, even when the tank 40 is extracted, it is possible to prevent the condensed water from the dehumidifying unit 3 and the falling water from the vaporizing element 41 from dropping on the bottom surface of the main body casing 10. 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.

  In the state where the tank 40 is extracted from the main casing 10, the vaporizing element 41 can be taken out from the outlet 13 by opening the door 16 as shown in FIG. At this time, as shown in FIG. 14, the humidified water receiver 54 of the drain pan 50 is in contact with the vaporizing element 41 in a state where the vaporizing element 41 is accommodated in the main body casing 10. When the vaporizing element 41 is taken out from the main body casing 10, the drain pan 50 is further inclined so that the position of the auxiliary container 53 is lowered, and more water can be held.

<Water outflow suppression measures when the main casing falls down>
In the present embodiment, measures are taken to minimize the outflow of water when the main casing 10 falls, and will be described below with reference to the drawings. FIG. 15 is a perspective view of the tank as viewed from above. In FIG. 15, the lid 401 of the tank 40 is provided with a water supply / drain port 402 at the left center in the plan view of FIG. 15, and a water intake port 403 is provided from approximately the center to the right end center in the plan view of FIG.

  The water supply / drain port 402 is an opening for supplying water to the tank 40 and discharging water from the tank 40, and the water intake port 403 is an opening in which the water wheel 42 is disposed. As described above, the water supply / drain port 402 and the water intake port 403 are arranged at the substantially center, so that even when the main body casing 10 falls down and the tank 40 is inclined by approximately 90 °, water is kept in the tank 40 as much as possible. I am doing so.

  For example, when the main body casing 10 falls to the front, water can be retained from the lower end in the plan view of FIG. 15 to the line L1. Moreover, when the main body casing 10 falls back, water can be retained from the upper surface of FIG. 15 to the line L2. In the present embodiment, the water supply / drainage port 402 is closed by a stopper 49 (see FIG. 11) except during water supply and drainage, so that when the main body casing 10 falls down, water flows out of the water supply / drainage port 402. Is prevented.

  Further, when the fallen main body casing 10 is put in a normal posture or when the main body casing 10 is shaken, a flange 404 is provided around the water intake port 403 in order to prevent water from undulating and jumping out from the water intake port 403. Is provided. When the water intake port 403 is viewed from the side, the height position of the water intake port 403 is lower than the edge of the lid 401, and the surface connecting the water intake port 403 and the edge of the lid 401 is formed by a gently inclined surface 401a. ing. The water that jumps over the flange 404 flows on the inclined surface 401 a toward the flange 404. Since the notch 405 is formed in the flange 404, the water flowing on the inclined surface 401a reaches the corner between the flange 404 and the inclined surface 401a and further passes through the notch 405 from the corner. The process proceeds to 403 and is collected in the tank 40.

  Further, the edge of the lid 401 is surrounded by a rib 406 protruding in the vertical direction. Even when the water surface in the tank 40 undulates and water jumps out of the water intake port 403, jumps over the flange 404, and rises up the inclined surface 401a, the wall of the rib 406 is about to spill. Stop it. As a result, scattering of water around the tank 40 is prevented.

  16 is a partial cross-sectional view taken along line AA in FIG. In FIG. 16, a concave groove 407 that is recessed toward the inside of the rib 406 is formed at a position opposite to the rib 406 of the lid 401. The lid 401 comes into close contact with the tank 40 by fitting the concave groove 407 of the lid 401 and the opening end of the tank 40. Further, since the concave groove 407 is used as a stealing meat when the rib 406 is molded, sink marks at the time of molding the rib 406 are prevented.

<Features>
In the humidity control air cleaner 1, the lid 401 is mounted on the side that becomes the upper surface when the tank 40 is stored in the main body casing 10. The lid 401 has a water supply / drain port 402 and a water intake port 403. The water supply / drain port 402 and the water intake port 403 are formed on or near the center line of the lid 401 extending in the longitudinal direction of the main body casing 10. As a result, when the main body casing 10 falls down in either the front side or the back side, all the water in the tank 40 is prevented from flowing out from the water supply / drain port 402 and the water intake port 403.

  In addition, since a flange 404 extending in a substantially vertical direction is formed around the water intake port 403, when the water surface in the tank 40 undulates due to shaking of the main body casing 10, the flange 404 is moved from the water intake port 403. Since the progress of the water that is about to jump out is hindered, the scattering of water is suppressed.

  Further, since the water intake port 403 is at the lowest position of the lid 401 and the lid 401 is formed with an inclined surface 401a that is inclined toward the water intake port 403, the water splashed over the flange 404 is moved to the inclined surface 401a. It flows and returns to the corner between the flange 404 and the lid 401. Since a notch 405 is formed in a part of the flange 404, the water passes through the notch 405 to the water intake 403 and enters the tank 40. As a result, water does not stay on the upper surface of the tank, and accumulation of scale and the like is prevented.

  As described above, if the present invention is used, it is useful for a device using water stored in a tank, particularly for a floor-type humidity control device in which the tank is inserted and removed in a substantially horizontal direction with respect to the main body.
