Description

  The present invention relates to a blowing direction changing device, and more particularly to a blowing direction changing device used in a dehumidifier.

  Conventionally, as a blowing direction conversion device, a configuration in which a main wind direction plate is rotatably provided in a ventilation frame portion formed on a lid, and a sub wind direction plate is rotatably attached to the main wind direction plate is known (for example, Patent Document 1).

JP 2004-251585 A

  However, the air blowing direction changing device has a problem that it is easily damaged because it is provided in a portion exposed to the outside. The blowing direction needs to be changed by directly gripping and rotating the main wind direction plate and the sub wind direction plate by hand. Moreover, even if the air blowing direction is determined, there is a problem that a sufficient air volume cannot be obtained due to the structure or the air is blown to an unnecessary portion. Moreover, when rotating a ventilation direction converter automatically, a ventilation direction can only be changed only within a fixed range.

  Then, this invention makes it a subject to provide the ventilation direction conversion apparatus which can supply sufficient air volume to a desired direction, and can set a ventilation range freely, without operating directly by hand.

As a means for solving the above problems, the present invention provides:
The blowing direction changing device
A plurality of guide plates arranged in parallel in the thickness direction at a predetermined interval, and a support plate that integrates both ends of the guide plates, are rotatably arranged in the casing, and are guided by a blowing position that stops. And a blowing direction conversion means capable of changing the blowing direction by changing the inclination angle of the plurality of air flow paths formed by the support plate, and
Driving means for driving the air direction changing means to rotate forward and reverse;
A blowing direction selecting means for selecting a blowing direction by the blowing direction converting means and positioning at the first blowing position or the second blowing position;
Control means for stopping the air blowing direction converting means at the air blowing positions corresponding to the air blowing direction by driving and controlling the driving means based on the air blowing direction selected by the air blowing direction selecting means,
With
Forming a stopper on the guide plate of the blowing direction changing means;
A stopper receiving portion for restricting the rotation range to the first air blowing position and the second air blowing position by contacting the stopper portion to the casing by rotating the air blowing direction changing means forward and backward by the driving means. Forming,
While the air blowing direction conversion means is positioned at the first air blowing position, the air blowing direction conversion is enabled while air can be blown in the first direction through some of the air flow paths. With the means positioned at the second air blowing position, the air can be blown in the second direction through the other air flow paths except the part of the plurality of air flow paths ,
The blowing direction conversion means can be further positioned at a third blowing position between the first blowing position and the second blowing position,
In the third air blowing position, the air is blown in the third direction by the partial air flow path, and the fourth air flow by the other air flow path excluding the partial air flow path among the plurality of air flow paths. It is set as the structure which can blow in the direction simultaneously .

  With this configuration, if the blowing direction conversion means is rotated in the casing, the inclination angle of the air passage is changed, and the blowing direction can be changed. And if a ventilation direction is selected by the ventilation direction selection means, a control means will rotate a ventilation direction conversion means so that the ventilation to the selected ventilation direction can be obtained, and it will stop at the ventilation position. Thereby, even if it arrange | positions a ventilation direction conversion means in a casing, it becomes possible to select a desired ventilation direction automatically automatically and to blow.

  The air blowing direction selecting means can select a range designation mode for rotating the air blowing direction converting means forward and backward within a predetermined angle range, and the control means is selected by the air blowing direction selecting means. In this case, it is preferable that the driving unit is driven and controlled so that the blowing direction changing unit rotates forward and backward between two blowing positions that define a specified range of the blowing positions.

  With this configuration, it is possible not only to blow air at a predetermined position, but also to rotate the blowing direction conversion means forward and backward between any two blowing positions among selectable blowing positions. Therefore, it is possible not only to blow in a specific direction but also to blow in an arbitrary range.

It is preferable that a part of the plurality of air flow paths can be blown in the first direction by changing the direction in the middle of the flow paths to be inclined.

  Both side portions of the guide plate are preferably located on the outer peripheral surface of the virtual cylindrical space.

  By this structure, it can be set as the most suitable structure for rotating a ventilation direction conversion means and converting a ventilation direction.

The stopper portion is formed of an extending portion that is formed on a central plate located at the rotation center among the guide plates of the blowing direction changing means and protrudes to the outer diameter side beyond the outer peripheral surface of the virtual cylindrical space. preferable.

  The blowing direction changing means is formed with a direction changing portion bent in a direction intersecting the guide plate from the middle part of the parallel air passage formed by the guide plate, and the direction changing portion is the parallel air passage. It is preferable that the structure does not have an undercut portion that can be formed only by a mold that opens on both sides of the passage.

  With this configuration, the blowing direction changing means can be mass-produced at a low cost and can be made into an integral structure as a molded product, which is advantageous in terms of strength.

  When the air flow direction switching means is not located in either the first air blowing position or the second air blowing position when the air blowing direction is switched, the control means drives the drive means to control the air blowing direction converting means. It is preferable that the first air blowing position or the second air blowing position is once positioned and then rotated in the selected air blowing direction.

  With this configuration, the zero point correction can always be performed, and the stop position of the blowing direction converting means, that is, the blowing position can be made accurate.

  The guide plate can prevent foreign matter from entering from the outside at the second air blowing position, and the control means drives and controls the driving means to turn the air blowing direction changing means to the second air blowing when OFF. It is preferable to position it at a position.

  With this configuration, foreign matter does not enter the inside when it is turned off, causing problems, and can be used with confidence.

  According to the present invention, since the blowing direction changing means is disposed in the casing so that it cannot be directly operated by hand, there is no fear of damage due to external force. Further, the air blowing direction can be changed by a simple mechanism that simply rotates the air blowing direction changing means. Further, if the air blowing direction is selected by the air blowing direction selecting means, the driving means is driven and controlled by the control means, and the air can be automatically blown from the air blowing direction selected by the air blowing direction converting means.

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

<Overall configuration>
FIG. 1 shows a perspective view of a dehumidifier according to the present embodiment, and FIG. 2 shows a plan view thereof. As shown in FIG. 3, the dehumidifier has a dehumidifying passage and a regeneration passage formed in the casing 1.

  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.
As shown in FIG. 12, the control unit 100 is in an on state, and according to the selected mode, the motor 5 </ b> A for rotation of the louver 5, the motors 2 </ b> A and 6 a for driving the main fan 2 and the sub fan 6, and the dehumidifying rotor 4. 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 (EPDM) or silicon rubber in an annular shape, and is attached to the opening edge. 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 positioned in the widened portions of the guide holes 43a and the vertically long communication portions 44 of the radiator portions 36 and 37, respectively. 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, by tightening the screws, a member having a sufficiently large strength as compared to the portion constituting the radiator 3, that is, the cylindrical portion 48 b of the first seal member 48 and the passage member 50. Each radiator portion can be assembled with a predetermined dimension in the thickness direction by the screwing portion 54 with high accuracy. 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.
