Description

  The present invention relates to a dehumidifier, and more particularly to a dehumidifier characterized by the structure of a radiator that condenses high-humidity air generated by regenerating a dehumidification rotor.

  Conventionally, in a dehumidifier, air taken in from the outside is dehumidified by a dehumidifying rotor and discharged to the outside. The dehumidification rotor is recovered by evaporating moisture absorbed by heating with a heater and condensing it with a radiator. The radiator is made of metal or resin. There is a problem that the metal one is heavy and expensive. For this reason, recently, resin radiators have been used (see, for example, Patent Document 1).

JP 2004-286276 A

  However, the resin radiator is light and inexpensive, but has a problem that heat exchange ability is inferior to that of metal. For this reason, it is necessary to devise for increasing the surface area with respect to the volume as much as possible. However, if the configuration is simply divided into two parts, there is a problem that air leakage cannot be avoided at the connecting portion, and the desired heat exchange performance cannot be obtained.

  Accordingly, an object of the present invention is to provide a dehumidifier capable of accurately preventing air leakage and improving heat exchange performance despite having a split-type resin radiator.

  As a means for solving the above-mentioned problems, the present invention provides a dehumidification passage in which air from outside is taken into the casing, dehumidified by the dehumidification rotor and discharged to the outside, and moisture absorbed by the dehumidification rotor. A dehumidifier comprising a regeneration passage that is evaporated by heat from a heater, supplied into a radiator, condensed, and collected, wherein the radiator includes a plurality of hollow radiator portions made of a synthetic resin material. Each of the radiators is provided with an entrance / exit for communicating the internal space with each other, and an escape portion formed around the entrance / exit, and the opening of the entrance / exit is provided between the radiators. A seal member having an annular portion that abuts on an edge portion and a connecting portion that is disposed on the escape portion and has rigidity higher than that of the radiator is disposed, and each radiator portion is disposed via the connecting portion. It is obtained by sintering.

  With this configuration, not only the heat exchange performance is improved by dividing the radiator, but the sealing member disposed between the radiator portions can sufficiently improve the airtightness of the connection portion of each radiator. That is, the sealing member is improved in the airtightness of the connecting portion by the annular portion that abuts the opening edge. In addition, the radiator parts are connected to each other by using a connecting part having higher rigidity than the radiator part. For this reason, a radiator part does not deform | transform partially or the press-contact force of a connection part does not become insufficient. Therefore, the entrance / exit portions can always be connected to each other with a desired contact pressure, and the desired airtightness can be ensured.

  It is preferable that a seal portion having rigidity lower than that of the radiator is provided at an opening edge portion of the entrance / exit portion, and when the radiator portions are integrated via the connecting portion, the annular portion is pressed against the seal portion.

  With this configuration, it is possible to further improve the airtightness.

  It is preferable that a plurality of communicating portions are arranged in parallel with each of the radiator portions, a sheet-like portion is formed in the communicating portions, and the sheet-like portion is sandwiched between the connecting portions by a screw head and integrated. .

  With this configuration, the radiator portions can be connected with a simple configuration that is simply screwed.

  The radiator is disposed in the dehumidification passage of the casing so as to be inclined with respect to a horizontal plane. Among the radiator parts constituting the radiator, the radiator part positioned above has a lower position by being inclined. A plurality of outflow holes are formed in the formed portion, and an inflow hole to which each of the outflow holes is connected is formed in the radiator portion positioned below, and between the outflow hole and the opening edge of the inflow hole. It is preferable to include a second seal member formed by connecting the annular portions positioned to each other.

  With this configuration, the condensed water generated in the radiator portion positioned on the upper side can be forced to flow into the radiator portion positioned on the lower side without difficulty, and airtightness at that time can be ensured.

  Of the radiator parts constituting the radiator, a passage member is mounted via an inlet / outlet part of the uppermost radiator part, and the passage member is a stepped cylindrical part located in each of the radiator parts to be stacked. And a screwing portion formed on the outer peripheral side of the tubular portion, a sealing member is disposed between the radiator portions, and a screw is inserted from the communicating portion into the communicating portion of the sealing member, and a passage member is provided. It is preferable that the screw is fixed to the screw fixing portion.

  With this configuration, the plurality of radiator portions can be integrated by the passage member and the seal member. For this reason, it can be handled as a module product, and an airtightness test can be performed in this state. Therefore, even if it is assembled in the casing after the airtightness test is completed, the confirmed airtightness is not impaired.

  The radiator part is preferably formed with a shielding plate that blocks ventilation in a portion other than the communication part in the casing.

  With this configuration, it is possible to regulate the flow of air in the dehumidifying passage at a low cost without requiring a separate member.

  According to the present invention, the radiator is divided into a plurality of radiator portions, a seal member is disposed between them, and the radiator portions are connected to each other at the connecting portion, so that desired airtightness is secured. It becomes possible to improve the heat exchange performance.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

<Overall configuration>

  An air flow is formed by the main fan 2 in the dehumidifying passage. That is, when the main fan 2 is driven, ambient air (outside of the casing 1) is taken into the dehumidifying passage. The taken-in air passes through the outside of the radiator 3 that is a heat exchange means, is dehumidified by a part of the dehumidification rotor 4 that is a dehumidification means, and then passes through the louver 5 that is a blowing direction changing means from the main fan 2. Are blown out in a predetermined direction.

  An air flow circulated by the sub-fan 6 is formed in the regeneration passage. That is, the air blown out from the sub-fan 6 is heated by the heater 7 which is a heating means, passes through the remaining portion of the dehumidifying rotor 4, is regenerated, and is condensed through the radiator 3, It returns to the sub fan 6 and circulates.

  The condensed water in the radiator 3 is collected in the main tank 9 through the sub tank 8.

The number of rotations of the rotation motor 4A and the energization amount to the heater 7 are controlled via the heater energization control circuit 7A. Further, based on the detection signals from the water level detection means 9b and the tank detection means 9c, the lighting of the LED of the tank information section 35 of the display panel 24 is controlled via the display panel control circuit 24a, and the lighting of other display sections. To control.

<Casing>
The casing 1 is made of a synthetic resin material, and as shown in FIG. 1, a cylindrical body portion 10, a lid portion 11 attached to an upper opening portion of the body portion 10, and a bottom portion 12 attached to a lower opening portion. It consists of and.

  As shown in FIG. 3, a first partition plate 13 is provided inside the upper opening of the body portion 10. A communication hole 13a is formed in the first partition plate 13, and a main fan 2 described later is disposed on the upper surface side so as to cover the communication hole 13a. A pair of support walls 14 are formed on the upper surface of the first partition plate 13 on the side opposite to the position where the communication hole 13a is formed. A louver 5 described later is rotatably supported on the support wall 14. Furthermore, the inclined surface 15 (here 45 degree | times with respect to a horizontal surface) extended toward diagonally downward is formed in the part ahead from the position in which the support wall 14 was formed.

  An opening 10 a is formed on the front side of the lower half of the body 10, and a tank accommodating portion 17 for accommodating the main tank 9 is formed therein by the second partition plate 16. A sub tank 8 described later is formed on the upper surface of the second partition plate 16.

  A recess 18 is formed in a part of the lower half side surface and the back surface of the body portion 10 so as to be recessed by a predetermined dimension from the outer surface. Air suction ports 19a and 19b for taking in ambient air are formed in the upper portion of the recess 18 on the side surface and the inner bottom surface partitioned by the guide wall 19c. The recess 18 is covered with a cover 20 fitted with a filter. The air inlets 19a and 19b are formed in a lattice shape so that no foreign matter can be inserted into the interior with the cover 20 removed from the recess 18. A humidity sensor 21 is disposed on the inner side in the vicinity of the air suction ports 19a and 19b. The recess 18 allows suction from the lower side via the recess 18 when ambient air is sucked from the air suction ports 19a and 19b. Thereby, relaxation of the flow resistance of air at the time of suction is achieved. Further, the suction from the air suction port 19b by the guide wall 19c is restricted from the lower side of the recess 18. Thereby, the filter attached to the cover 20 can be used almost uniformly over the whole, and the lifetime improvement is achieved.

  As shown in FIG. 2, the lid portion 11 has a blowout port 22 formed on the back side. The air outlet 22 is formed in a lattice shape, and has a structure in which foreign matter is less likely to enter. Further, as shown in FIG. 1, an exhaust duct member 67 is detachably attached to the air outlet 22. An auxiliary tool (not shown) is connected to the exhaust duct member 67 and used for drying boots and the like. Inside the lid portion 11, a temperature sensor 23 is disposed on the upstream side of the air flow from the louver 5 (for example, the first partition plate 13).

  The lid 11 is provided with a display panel 24 as shown in FIG. The display panel 24 includes various switches and a display unit as shown in FIG.

  The switches include a louver direction changeover switch 25, an auto louver off / on switch 26, a dehumidifying switch 27, a drying switch 28, an operation off / on switch 29, and a off timer switch 30.

  The louver direction changeover switch 25 can select a blowing pattern (six here) according to the number of times of pressing. Further, LEDs 25a, 25b, and 25c are provided at three locations in the vicinity of the louver direction changeover switch 25, and a lighting pattern (lighting position) is changed corresponding to each of the air blowing patterns. Table 1 shows the air blowing directions that can be selected and the lighting states of the LEDs 25a, 25b, and 25c. Note that each time the louver direction changeover switch 25 is pressed once, the air blowing and lighting pattern changes from the top of Table 1 to the lower pattern, and then returns to all directions again downward.

  When the selected air blowing direction extends over a plurality of directions, all the LEDs 25a, 25b, and 25c indicating the air blowing directions are turned on, and the LEDs indicating the current air blowing direction blink (or change color). May be) For example, when all directions are selected, all the LEDs 25a, 25b, and 25c are lit. In the state where the air is blown upward, only the LED 25a at that position is blinking. Thereby, the user can grasp the air blowing range and the current air blowing direction at a glance.

  The auto louver off / on switch 26 is used to select whether the louver 5 is automatically rotated or stopped. If the user wants to fix the blowing direction at a desired position, the auto louver off / on switch 26 may be pushed to “off” when the louver 5 is automatically rotated and the blowing direction becomes the target direction.

  The dehumidifying switch 27 is a switch for selecting a dehumidifying mode. Here, three modes of “automatic standard”, “strong”, and “quiet” can be selected. When the “automatic standard” mode is selected, the rotation of the main fan 2 and the energization of the heater 7 are controlled based on the humidity detected by the humidity sensor 21. The heater 7 is duty-controlled (repeats on and off). The drying switch 28 is a switch for selecting a mode to be used when drying laundry or boots. When the drying switch 28 is operated, the heater 7 is kept on. The operation off / on switch 29 is a main switch for turning on / off the power. The turn-off timer switch 30 is a switch for setting the time from the start of the operation of the dehumidifier to the automatic stop.

  The display unit includes a humidity monitor unit 31, an air blowing mode unit 32, a drying mode unit 33, a timer unit 34, and a tank information unit 35. The humidity monitor unit 31 changes the lighting position of the LED in three stages of “high humidity”, “appropriate humidity”, and “low humidity” to notify the humidity state. The air blowing mode unit 32 changes the lighting position of the LED in three stages of “automatic standard”, “strong”, and “silent” to notify the air blowing state. The drying mode unit 33 has six times of “quick drying”, “power saving”, “night drying”, “futon”, “shoes / boots”, and “sports shoes” by pressing the drying switch 28 (1-6 times). The drying mode can be sequentially selected (returns to “quick drying” by the seventh press). The timer unit 34 indicates how many hours after the start of operation the operation is to be stopped. Here, the number of times (1 to 4 times) the turn-off timer switch 30 is pressed indicates “1”, “2”, “4”, “6”. ”Can be sequentially selected (returns to“ 1 ”by the fifth press). The tank information part 35 indicates “full water” when the color is green, and “no tank” when the color is red.

<Radiator>
As shown in FIGS. 7 to 9, the radiator 3 includes a first radiator portion 36 and a second radiator portion 37 having substantially the same shape. By configuring the radiator 3 with two radiator parts, it is possible to sufficiently increase the surface area. However, it is also possible to configure with three or more radiator sections. Each radiator part is formed by vacuum-forming or pressure-forming a synthetic resin material such as polyethylene or polypropylene, and bonding the obtained two panels together. Here, the thickness of the synthetic resin constituting the radiator 3 is suppressed to 1 mm or less, and the heat exchange performance between the air passing inside and outside is enhanced. Further, the bonded portion is extended to the side to form a shielding portion 3a that functions as a shielding plate. That is, when the radiator 3 is assembled in the casing 1, all the air flowing outside the radiator 3 in the dehumidifying passage is guided to the dehumidifying rotor 4.

  The first radiator portion 36 is hollow, and a first inlet 38 and a first outlet 39, and a second inlet 40 and a second outlet 41 are formed at opposing positions on both ends of both panels. Seal portions 42 are provided at the opening edges of the inlet and outlet. The seal portion 42 is made of a sealing material such as nitrile rubber (EDPM) or silicon rubber in an annular shape, and is adhered to the opening edge portion. A guide hole 43a for positioning a cylindrical portion 48b of a first seal member 48 to be described later and a screw hole 43b for screwing to a passage member 50 to be described later are formed around the inlet and the outlet, respectively. Has been. Further, a part of a vertically long communication portion 44 to be described later is widened, and the cylindrical portion 48b of the first seal member 48 is positioned similarly to the guide hole 43a.

  The first radiator section 36 has a plurality of vertically long communication sections 44 arranged in parallel between the inlet 38 and the outlet 41. Each vertically long communication portion 44 is formed with a sheet-like portion 45 that protrudes inward from a part of the inner surface. The sheet-like portion 45 is sandwiched between the head portion of the screw and the tubular portion 48 b of the first seal member 48 when screwing, which will be described later. The vertically long communication portion 44 is provided to increase the surface area and promote heat exchange between high-temperature and high-humidity air flowing inside and low-temperature air flowing outside. The vertically long communication part 44 approaches the side part at two positions a and b, and suppresses the air flow at these positions a and b. Therefore, the air that has entered from the inlet flows in an approximately N shape in the internal space, and heat exchange is performed in almost the entire region.

  Further, the first radiator portion 36 has a water flow hole 36a at one location on the upper surface and an outflow hole 46 at two locations on the lower surface. Condensed water from a sub-fan 6 described later flows into the water flow hole 36a. The outflow hole 46 is for allowing the condensed water generated inside the first radiator section 36 to flow to the second radiator section 37. The sealing part 42 is stuck to the opening edge part of each outflow hole 46 like the above. Further, in the vicinity of each outflow hole 46, a guide hole 47a and a screw hole 47b formed in the shielding plate are provided.

  The second radiator unit 37 has a configuration substantially similar to that of the first radiator unit 36. The second radiator section 37 has an inflow through which an outflow hole 46 of the first radiator section 36 communicates in addition to the inlet 37a and the outlet 37b connected to the first outlet 39 and the second inlet 40 of the first radiator section 36, respectively. A hole 37c is formed. The opening edge of each inflow hole 37c is formed in a cylindrical shape, and can be positioned by engaging with a cylindrical portion 49b of a second seal member 49 described later. Further, the second radiator portion 37 is formed with a cylindrical outflow portion 37d connected to a sub tank 8 described later.

  In addition, a first seal member 48 and a second seal member 49 are disposed at the connection portion between the inlet and the outlet, and the outflow hole 46 and the inflow hole, respectively.

  As shown in FIGS. 7 and 8, the first seal member 48 includes an annular portion 48 a and a cylindrical portion 48 b that is arranged in three equal portions on the outer peripheral portion of the annular portion 48 a. The upper surface of the annular portion 48a is in surface contact with the seal portion 42 adhered around the first outlet 39 (or the second inlet 40) of the first radiator portion 36. Further, the lower surface of the annular portion 48a is in surface contact with the seal portion 42 attached around the inlet 37a (or 37b) of the second radiator portion 37. The cylindrical part 48 b is positioned in the guide hole 43 a formed in each radiator part 36, 37 and the widened part of the vertically long communication part 44. And the screw for fixing the channel | path member 50 to the radiator 3 is penetrated by the cylindrical part 48b so that it may mention later.

  As shown in FIGS. 7 and 8, the second seal member 49 has a rod shape, and is formed with an annular portion 49a and cylindrical portions 49b located on both sides of the annular portion 49a on both ends thereof. is there. The upper surface of the annular portion 49 a is in surface contact with the periphery of the outflow hole 46 of the first radiator portion 36. The lower surface of the annular portion 49 a is in surface contact with the periphery of the inflow hole 37 c of the second radiator portion 37. The cylindrical portion 49b is positioned in the guide holes 47a formed in the radiator portions 36 and 37, is sandwiched between the shielding portions 3a, and is connected to the radiator via screw holes 47b formed in a part of the shielding portions 3a. A screw for fixing the passage member 50 is inserted into the passage 3.

  The passage members 50 are connected to the first inlet 38 and the second outlet 41 of the first radiator section 36, respectively. The passage member 50 has a two-stage structure including a large diameter part 51, a medium diameter part 52, and a small diameter part 53. As will be described later, the end surface of the large-diameter portion 51 is formed obliquely to attach the radiator 3 to the first partition plate 13 positioned on the horizontal plane. Screw fixing portions 54 are formed almost uniformly in the circumferential direction at three locations on the outer peripheral portion of the large diameter portion 51. Screws inserted into the respective cylindrical portions 48 b of the first seal member 48 are screwed into the screw fastening portions 54. Further, at three positions on the outer peripheral portion of the large-diameter portion 51, fixing extension portions 55 are formed at intermediate positions of the screwing portions 54. Each fixing extension 55 is formed with a through hole, and the passage member 50 can be screwed to the second partition plate 16 provided in the casing 1. The medium diameter portion 52 has an opening formed on the outer peripheral surface, is inserted from the inlet, and is positioned inside the first radiator portion 36. The small diameter portion 53 is formed with an opening on the outer peripheral surface, similarly to the medium diameter portion 52, protrudes from the outlet of the first radiator portion 36, and is positioned inside the second radiator portion 37.

  The radiator 3 having the above-described configuration is assembled as follows. That is, the first seal member 48 and the second seal member 49 are disposed between the first radiator portion 36 and the second radiator portion 37. At this time, the cylindrical portion 48b of the first seal member 48 is respectively formed in the widened portions of the guide holes 43a and the vertically long communication portions 44 of the radiator portions 36 and 37 (both of which constitute the escape portion according to the present invention). Position. And the passage member 50 is arrange | positioned at the 1st inlet_port | entrance 38 and the 2nd exit 41 of the 1st radiator part 36, respectively. The passage member 50 is in a state where the screwing portion 54 is positioned in the guide hole 43 a and the vertically long communication portion 44 and is opposed to the cylindrical portion 48 b of the first seal member 48 via the sheet-like portion 45. On the other hand, the outflow hole 46 of the first radiator part 36 and the inflow hole 37 c of the second radiator part 37 are positioned in the annular part 49 a of the second seal member 49. Further, the cylindrical portion 49 b is positioned in each guide hole 47 a of the first radiator portion 36 and the second radiator portion 37.

  Then, a screw is inserted into the guide hole 43a and the vertically long communication portion 44 from the lower surface side of the second radiator portion 37, and is screwed into the screw fastening portion 54 of the passage member 50 via the cylindrical portion 48b of the first seal member 48. . When the screw is tightened, the sheet-like portion 45 formed in the longitudinal communication portion 44 of the second radiator portion 37 is sandwiched between the head portion of the screw and the cylindrical portion 48 b of the first seal member 48. Further, a sheet-like portion 45 formed in the vertically long communication portion 44 of the first radiator portion 36 is sandwiched between the tubular portion 48 b and the screwing portion 54 of the passage member 50. The second seal member 49 is in a state in which the annular portion 49 a is sandwiched between the first radiator portion 36 and the second radiator portion 37.

  In the radiator 3 assembled in this way, a member (corresponding to the connecting portion according to the present invention) having a sufficiently large strength as compared with the portion constituting the radiator 3 by tightening the screws, that is, the first seal member 48. Each of the radiator portions can be assembled with high accuracy with a predetermined dimension in the thickness direction by the cylindrical portion 48b and the screwing portion 54 of the passage member 50. Therefore, a desired pressure contact force can be obtained between the annular portions 48a and 49a of the first seal member 48 and the second seal member 49 and the seal portions 42 of the radiator portions 36 and 37, and each of the components constituting the radiator 3 can be obtained. Good airtightness of parts. And these can be handled as 1 unit and an airtight test can be performed in this assembly state. For this reason, after assembling to the casing 1, the airtightness of the connecting portion where the air flows in the radiator 3 is not impaired. That is, the result of the airtight test can be reflected on the product as it is. Also, only three screw fixings are required, and the assembly time can be shortened. In addition, since the vertically long communication portion 44 is partially used, it is not necessary to add an extra structure for screwing or the like to the radiator 3 so much. In particular, if the screwing is performed at two places, this effect becomes even more remarkable. However, from the viewpoint of airtightness, there may be four or more locations.

  The radiator 3 that has been subjected to the airtight test is fixed to the first partition plate 13 attached in the casing 1 by screwing through the screw holes 43b. The fixed radiator 3 is inclined so that the outflow hole 46 is located on the lower side with respect to the horizontal plane (here, 11 degrees). As a result, the condensed water can smoothly flow down to the sub tank 8.

<Dehumidification rotor>
As shown in FIG. 3, the dehumidifying rotor 4 has a disk shape in which the rotor body 56 is held by a holding member 57. For the rotor body 56, a ceramic honeycomb bonded with zeolite, silica gel or the like is used. The dehumidifying rotor 4 is provided between the first partition plate 13 and the second partition plate 16 on the upper surface of a third partition plate 68 that separates the inside of the casing 1 up and down. The holding member 57 is a heater housing chamber 58 in which a portion corresponding to a quarter region of the upper surface of the dehumidifying rotor 4 is expanded in a substantially fan shape, and the remaining three-quarter region is the rotor body 56. It is open to allow ventilation and is located in the dehumidifying passage. The heater accommodating chamber 58 is connected to a sub fan case 65 in which a sub fan 6 described later is accommodated, and a heater 7 described later is accommodated therein. When the operation off / on switch 29 is operated to enter the operation state, the motor 4A is driven, and the rotor body 56 rotates at a predetermined speed in the holding member 57.

<Main fan>
As shown in FIG. 3, the main fan 2 has a main fan case 59 provided with a main sirocco fan 60 that can be driven to rotate by a motor 2A. When the main sirocco fan 60 is rotated, air is sucked from the suction port in the center and is blown out from the outlet 22 as a vortex in the main fan case 59. The upper wall formed on the inner surface of the air outlet 22 is a stopper receiving portion 61 that projects obliquely downward. The stopper receiving portion 61 comes into contact with a stopper portion 5a of the louver 5 described later and an extended portion 62a described later, so that the rotation of the louver 5 is restricted.

<Louvre>
As shown in FIG. 3, the louver 5 has a configuration in which a circular support plate 63 is integrated with both ends of a guide plate 62 disposed at a predetermined interval. However, the intermediate portion of the guide plate 62 is also appropriately reinforced by the support plate 63.

  As shown in FIG. 10, the guide plate 62 is the largest at the center (center plate 62A), and one of the side edges extends from the virtual cylindrical space formed between the support plates 63 on both sides. It is the installation part 62a. As will be described later, the extended portion 62a functions as a stopper and a shielding plate.

  In addition, a blowing direction conversion unit 64 that directs the air flow obliquely is provided on the other side edge of the center plate 62A. The blowing direction conversion section 64 has a curved connection portion with the center plate 62A so that the air flow can be smoothly converted. The remaining guide plate 62 has both side edges positioned on the outer periphery of the virtual cylindrical space.

  The first guide plate 62B and the second guide plate 62C located on one side of the center plate 62A are arranged in parallel to form an air flow parallel to the center plate 62A. The third guide plate 62D and the fourth guide plate 62E located on the other side of the center plate 62A are parallel to the center position of the virtual cylindrical space. The third guide plate 62 </ b> D is a blowing direction conversion unit 64 that is parallel to the blowing direction conversion unit 64 from the center position of the virtual cylindrical space. The fourth guide plate 62E is a stopper portion 5a that extends from the center position of the virtual cylindrical space in a direction perpendicular to the previous portion.

  The support plate 63 has a shaft portion (not shown) formed at the center of the outer surface, and is rotatably supported by the support wall 14 formed in the casing 1. The driving force of the motor 5A is transmitted to one shaft portion via a gear (not shown). As the motor 5A, a servo motor or a stepping motor that can be driven forward and reverse is used.

  Since the louver 5 does not have an undercut portion as shown in FIG. 11, the louver 5 can be molded by simply opening and closing the mold A and the mold B. Therefore, the production cost of the mold can be reduced and it can be manufactured at low cost. Moreover, since it has a reasonable structure, it is excellent in terms of strength.

  And the louver 5 of the said structure rotates in the range of 135 degree | times from diagonally downward 45 degree | times to the vertically upward direction, and stops at a predetermined ventilation position, or forward / reverse rotation between arbitrary two ventilation positions By switching the air blowing direction.

  When the louver 5 is selected by operating the louver direction changeover switch 25, the louver 5 has a stopper receiving portion 61 of the main fan case 59 in which the extending portion 62a is fixed in the casing 1, as shown in FIG. It rotates in the clockwise direction until it comes into contact with and is positioned at the initial position (lower air blowing position). In this lower air blowing position, the air from the main fan 2 flows only through the parallel air flow path formed by the center plate 62A and the first and second guide plates 62B, and the air blowing direction is obliquely downward 45 degrees.

  When the upward direction is selected by operating the louver direction changeover switch 25, the louver 5 rotates counterclockwise until the stopper portion comes into contact with the stopper receiving portion 61 as shown in FIG. Positioned. In the upper air blowing position, the air from the main fan 2 flows only through the air flow path formed by the center plate 62A and the third and fourth guide plates 62D and 62E, and the air blowing direction is vertically upward.

  When the horizontal direction is selected by operating the louver direction changeover switch 25, the louver 5 is positioned at the horizontal position as shown in FIG.

  Further, when the louver 5 is operated by operating the louver direction changeover switch 25 to select the upper / horizontal direction, the louver 5 rotates forward / reversely between FIG. 10 (b) and FIG. 10 (c), and when the horizontal / downward direction is selected, When forward / reverse rotation is performed between FIG. 10 (a) and FIG. 10 (b) and all directions are selected, forward / reverse rotation is performed between FIG. 10 (a) and FIG. 10 (b).

<Sub fan>
Similar to the main fan 2, the sub fan 6 has a configuration in which a sub sirocco fan 66 is rotatably provided by a motor in a sub fan case 65. An air inlet (not shown) is connected to the second outlet 41 of the first radiator section 36, and the air outlet is connected to the heater accommodating chamber 58. A drainage part 65 a is formed in the sub fan case 65. The drainage portion 65a is formed in a conical shape whose sectional area gradually decreases toward the tip. The drainage portion 65 a is disposed at the lowest position in a state where the sub fan 6 is assembled to the dehumidifier, and is connected to the water flow hole 36 a of the second radiator portion 37.

  When changing the arrangement position of the sub-fan 6, there is a tradeoff with other components, but the radiator 3 is positioned on the lower side in almost the entire region. Therefore, the condensed water generated in the sub fan case 65 can surely flow down to the radiator 3 via the drainage part 65a. That is, the design position of the sub fan 6 can be determined without worrying about the position of the condensed water drainage.

<Heater>
A wound coil is used for the heater 7, and the power is controlled by the heater power control circuit 7a by the power supplied from a power source (not shown) to generate heat. The heater 7 is disposed in a heater housing chamber 58 formed in the holding member 57 of the dehumidifying rotor 4, and heats the air passing through the regeneration passage to supply the dehumidifying rotor 4, and also directly heats the dehumidifying rotor 4. Thereby, the moisture absorbed by the dehumidification rotor 4 can be evaporated, and the moisture absorption capability of the dehumidification rotor 4 can be recovered.

<Sub tank>
The sub-tank 8 is a conventionally known temporary storage tank for preventing condensed water from spilling out even when the main tank 9 is removed from the casing 1, and is formed on the upper surface of the second partition plate 16 provided in the casing 1. Has been. An inflow hole is formed on the upper surface of the sub tank 8 to which a cylindrical outflow portion provided in the second radiator portion 37 is connected. On the bottom surface of the sub-tank 8, that is, the bottom surface of the second partition plate 16, an opening / closing valve for opening the drain hole only when the main tank 9 is accommodated in the tank accommodating portion 17 is provided.

<Main tank>
The main tank 9 has a box shape with an open top, and a locking recess 9 a is formed on the front surface to be gripped by a finger and pulled out from the tank housing portion 17 of the casing 1. Inside the main tank 9, a floating water level detecting means 9b is provided. When the water level is detected by the water level detecting means 9b, the LED of the tank information unit 35 is lit in green. Whether or not the main tank 9 is accommodated in the tank accommodating portion 17 is detected by the tank detecting means 9c provided in the tank accommodating portion 17, and if not, the LED of the tank information portion 35 is red. It is turned on.

<Operation>
Next, the operation of the dehumidifier configured as described above will be described.

  If the operation off / on switch 29 is pressed and turned on, the motor for rotating the louver 5, the motor for driving the main fan 2 and the sub fan 6, and the dehumidifying rotor 4 according to the mode selected by each switch. The number of rotations of the rotation motor and the energization amount to the heater 7 are controlled.

  When the air blowing direction is selected by operating the louver direction changeover switch 25, first, regardless of the selected air blowing direction, the rotating motor is driven to rotate the louver 5 in the clockwise direction in FIG. Regardless of the previous stop position of the louver 5, the rotation time is a time during which the extended portion 62a of the center plate 62A is reliably in contact with the stopper receiving portion 61 and is prevented from further rotation. Thus, the louver 5 is always positioned at the initial position (lower position) shown in FIG. 10A before changing the blowing direction. Therefore, even if the louver 5 has been rotated from the previous stop position, since so-called initialization is performed, there is no fear of displacement. Then, the louver 5 is rotated by drivingly controlling the rotation motor so that the selected blowing direction is obtained.

  If the selected direction is a single direction (up, horizontal, down), the louver 5 is stopped at the corresponding position, but if it is in multiple directions (all, up / horizontal, horizontal / down), it is selected The louver 5 is rotated forward and backward depending on the direction. At this time, the LED in the selected direction is turned on, and the LED at the position where the louver is currently rotating is blinked. Thereby, the user can confirm the rotation range of the louver 5, that is, the selected blowing pattern at the lighting position. In addition, the current blowing direction can be seen at the blinking position. The louver 5 can be stopped at a desired position by operating the auto louver off / on switch 26 while confirming the blinking position of the LED or confirming the actual air blowing direction.

  The control when the dehumidifying switch 27, the drying switch 28, and the turn-off timer switch 30 are operated is the same as that conventionally known, and the description thereof is omitted here.
