  The present invention relates to a dehumidifier, and more specifically, a main fan for taking in air from an air inlet and blowing out dry air after dehumidification from an air outlet, and dehumidifying means for performing dehumidification of the taken-in air The present invention relates to a dehumidifier provided.

  As a dehumidifier, what is called a rotor type dehumidifier as disclosed in Patent Document 1, for example, is known. This type of dehumidifier allows air to pass through a dehumidification rotor impregnated with a hygroscopic agent such as zeolite so that moisture in the air is adsorbed to the dehumidification rotor and blows off the dehumidified dry air from the air outlet. The room is dried. In this type of dehumidifier, there is no structure that changes the blowing direction of the dry air blown from the air blowing port.

  Further, as disclosed in Patent Document 2, for example, in a cooling type dehumidifier using a compressor, a structure for changing the blowing direction of dry air exists as a conventional technique. In the structure disclosed in Patent Document 2, a louver for changing the air direction that can be rotated around a horizontal axis is provided at an air outlet, and the blowing direction of dry air is substantially horizontal from the upper direction by adjusting the angle of the louver. It is comprised so that it can change over a direction.

Japanese Patent Laid-Open No. 2001-227809.

  However, the louver of the conventional dehumidifier can be changed in the vertical direction around the horizontal axis as disclosed in Patent Document 2, but cannot be changed in the horizontal direction. In the case of this type of dehumidifier, in order to allow the dry air blown out from a relatively small air blowout outlet to spread throughout every corner of the room, a structure in which the blowout direction is changed to the horizontal direction is desirable, and the blowout direction is set to the horizontal direction. In the case of changing the range, the user can arbitrarily set the range to be changed, regardless of the positional relationship between the object to be dried (for example, laundry) and the dehumidifier. There is a demand that it is preferable in doing.

  The present invention has been made in view of the above points, and an object of the present invention is to make it possible to arbitrarily set the changing range in changing the blowing direction of the dry air blown from the air blowing port in the horizontal direction. It is what.

  In the present invention, as a first means for solving the above problems, a main fan for taking in air from an air inlet and blowing out dehumidified dry air from an air outlet and dehumidifying the taken-in air. In the dehumidifier having a dehumidifying means for performing, a louver for defining a blowing direction of dry air is rotatably provided at the air outlet, and a rotation angle setting means for setting a rotation angle range of the louver is additionally provided. Yes.

  With the above configuration, the rotation angle range of the louver can be arbitrarily set as desired by the user by the rotation angle setting means. Accordingly, the louver reciprocally swings within the rotation angle range desired by the user, and the desired dry air blowing direction can be obtained without moving the dehumidifier itself.

  In the present invention, as a second means for solving the above problem, in the dehumidifier having the first means, the rotation angle range is set by the rotation angle setting means while the louver is rotating. In such a configuration, a desired rotation angle range during the rotation of the louver can be set, and the user's desire can be easily adapted.

  In the present invention, as a third means for solving the above problem, in the dehumidifier provided with the first or second means, a rotation angle range set by the rotation angle setting means is set to a predetermined value. It can also be between the rotation start point and the rotation end point determined by the operation of the switch. In such a configuration, the start point and the end point of the rotation angle range of the louver can be obtained by operating the predetermined switch twice. This makes it possible to set the rotation angle range easily.

  In the present invention, as a fourth means for solving the above problem, in the dehumidifier having the third means, the rotation of the louver is performed until the rotation end point is determined after the rotation start point is determined. It can also be configured to continue, in which case the louver continues to rotate after the rotation start point is determined until the rotation end point is determined, while watching the rotation state of the louver. Since the rotation angle range can be set, a desired rotation angle range can be reliably set.

  In the present invention, as a fifth means for solving the above problems, in the dehumidifier having the third or fourth means, a single rotation angle setting button is adopted as the switch, and the rotation angle The rotation start point may be determined by the first operation of the setting button, and the rotation end point may be determined by the next operation of the rotation angle setting button. Two settings of the end point can be performed by two operations of one rotation angle setting button, and the operability is greatly improved.

  According to the first means of the present invention, it is provided with a main fan for taking in air from the air inlet and blowing out the dehumidified dry air from the air outlet, and dehumidifying means for performing dehumidification of the taken-in air. In the dehumidifier, a louver that prescribes a blowing direction of the dry air is rotatably provided at the air outlet, and a rotation angle setting unit that sets a rotation angle range of the louver is attached to the air outlet. The louver's rotation angle range can be set as desired by the user, so the louver will swing back and forth within the rotation angle range desired by the user, and the desired drying can be done without moving the dehumidifier itself. There is an effect that the air blowing direction can be obtained.

  As in the second means of the present invention, in the dehumidifier equipped with the first means, the setting of the rotation angle range by the rotation angle setting means can be performed while the louver is rotating, In such a configuration, a desired rotation angle range in the middle of the rotation of the louver can be set, and it is easy to adapt to the user's desire.

  As in the third means of the present invention, in the dehumidifier having the first or second means, the rotation angle range set by the rotation angle setting means is determined by the operation of a predetermined switch. It can also be between the start point and the rotation end point. In such a configuration, it is possible to set the start point and end point of the rotation angle range of the louver only by operating the predetermined switch twice. Easy to set up.

  As in the fourth means of the present invention, in the dehumidifier having the third means, the louver may continue to rotate until the rotation end point is determined after the rotation start point is determined. In such a configuration, the rotation angle range can be set while observing the rotation state of the louver from where the rotation of the louver is continued until the rotation end point is determined even after the rotation start point is determined. Thus, the desired rotation angle range can be set reliably.

  As in the fifth means of the present invention, in the dehumidifier equipped with the third or fourth means, a single rotation angle setting button is adopted as the switch, and the rotation angle setting button is operated by the first operation. The rotation start point is determined, and the rotation end point can be determined by the next operation of the rotation angle setting button. In such a configuration, the two settings of the rotation start point and the rotation end point are unified. This can be done by two operations of one rotation angle setting button, and the operability is greatly improved.

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

  The dehumidifier 10 has an outer case formed of a resin-made main body case 20 including a front case 21 and a rear case 22. In the main body case 20, a main fan 23, a main motor 24 that drives the main fan 23, a dehumidification rotor 25, a dehumidification motor 26 that rotationally drives the dehumidification rotor 25, a regeneration unit 27 incorporating a heater and the like, a front heat A heat exchanger unit including the exchanger 28 and the rear heat exchanger 29, a filter 30, a drain tank 31, and the like are accommodated.

  The main fan 23, which is a centrifugal fan, takes in the room air Wr from the air suction port 32 formed in the rear case 22 on the back side of the main body case 20, and the taken-in room air Wr is dehumidified by the dehumidifying rotor 25 or the like. It is. The dried air Wr ′ after the dehumidifying treatment is discharged into the room from the air outlet 33 provided at the upper part of the dehumidifier 10 by the main fan 23, and the dried air Wr ′ discharged into the room is dehumidified in the room, or Drying items such as clothes after washing.

  In the dehumidifier 10 according to the present exemplary embodiment, a dehumidifying unit is configured by the heat exchanger unit including the dehumidification rotor 25, the regeneration unit 27, the front heat exchanger 28 and the rear heat exchanger 29. The dehumidifying rotor 25 has a structure in which ceramic fiber paper is wound in a disk shape and fired at a high temperature so that zeolite as a moisture absorbent is impregnated. A hygroscopic agent other than zeolite can be used.

  The room air Wr taken in from the air suction port 32 by the main fan 23 is absorbed by moisture when passing through the dehumidification rotor 25, and the room air is dehumidified. A rotor gear 25 a that is a flat gear is provided on the outer periphery of the dehumidifying rotor 25, and a small-diameter motor gear 26 a that meshes with the rotor gear 25 a is fixed to the rotating shaft of the dehumidifying motor 26. When the dehumidifying motor 26 rotates, the dehumidifying rotor 25 is configured to rotate slowly around the central axis 34.

  As shown in FIG. 4, a metal case 27 a that constitutes the regeneration unit 27 is provided in a fan-shaped portion that is a part of the dehumidifying rotor 25. A regenerative heater 27b is mounted in the metal case 27a. Further, a regeneration air blowing path 27c communicates with the side of the metal case 27a, and an impeller of a regeneration fan 27d, which is a sirocco fan, is accommodated in the ventilation path 27c.

The regeneration air W ₁ blown by the regeneration fan 27 d is heated by the regeneration heater 27 b of the regeneration unit 27 and then applied from the front side to a regeneration zone composed of a fan-shaped portion that is a part of the dehumidifying rotor 25.

In the regeneration zone, moisture contained in the moisture absorbent of the dehumidifying rotor 25 is removed by the heated regeneration air W ₁ and the dehumidifying rotor 25 is dried. As a result, the moisture absorbing function of the moisture absorbent is recovered and regenerated, and moves to the dehumidifying zone again with the rotation of the dehumidifying rotor 25 to perform the dehumidifying process. The dehumidifying zone is a portion other than the fan-shaped regeneration zone.

The room air Wr taken from the air suction port 32 on the back side of the dehumidifier passes through the filter 30 and then passes through the slits 28d of the rear heat exchanger 29 and the front heat exchanger 28. At this time, heat is exchanged between the regeneration air W ₁ flowing inside the rear heat exchanger 29 and the front heat exchanger 28 and the indoor air Wr, and the high-temperature regeneration air W ₁ is cooled and the indoor air Wr is warmed. Thereafter, the indoor air Wr flows out of the slit 28 d and travels toward the dehumidifying rotor 25.

By the regeneration air W ₁ is cooled, the inside of the front heat exchanger 28 and the rear side heat exchanger 29, is removed moisture in air for regeneration W ₁ is condensation. Condensed water is collected while dropping inside, falls from a drain outlet formed at the lower end, and is stored in the drain tank 31. The regeneration air W _{1 from} which moisture has been removed is sent again from the front heat exchanger 28 and the rear heat exchanger 29 to the metal case 27a through the air passage 27c of the regeneration unit 27, and heated by the regeneration heater 27b to dehumidify. Used for regeneration of the rotor 25.

In the dehumidification rotor 25 heated by the regeneration air W ₁ heated in the regeneration zone, residual heat remains in the portion moved to the dehumidification zone by the rotation. The indoor air Wr heated through the slit 28d of the heat exchanger is dehumidified when passing through the dehumidification zone of the dehumidification rotor 25, and is further warmed by the dehumidification rotor 25 where the remaining heat remains, and the main fan 23 Then, the air is discharged from the air outlet 33 to the outside as dry air Wr ′. The dry air Wr ′ discharged to the outside from the air outlet 33 is air having a lower humidity and a higher temperature than the indoor air Wr taken from the air inlet 32.

  The bulging portion 62 above the louver shaft 60 has a substantially bowl shape, and forms a substantially bowl-shaped internal space 62a that bulges upward. As shown in FIGS. 5 and 6, two plungers incorporating springs are accommodated in the internal space 62a.

  The plunger includes a small diameter plunger 75 and a large diameter plunger 76. Both plungers 75 and 76 are cylindrical members, one of which is opened and the other is closed, and shaft projections 75a and 76a projecting outward are provided at the closed ends, respectively. In use, the open end sides of both plungers 75 and 76 are opposed to each other, and the small diameter plunger 75 is inserted into the large diameter plunger 76.

  When the small diameter plunger 75 is inserted into the large diameter plunger 76, a plunger spring 77 made of a coil spring is inserted into the small diameter plunger 75 in advance. The plunger spring 77 is longer than the small diameter plunger 75. When the plunger spring 77 is inserted into the small diameter plunger 75, the other end of the plunger spring 77 is connected to the open end of the small diameter plunger 75. It's popping out. Therefore, when the large-diameter plunger 76 is inserted on the outer periphery of the small-diameter plunger 75 with the plunger spring 77 inserted into the small-diameter plunger 75, the plunger spring 77 is attached in the direction in which both plungers 75 and 76 are separated.

First, with the plunger spring 77 inserted into the small diameter plunger 75, the large diameter plunger 76 is inserted on the outer periphery of the small diameter plunger 75 to form a plunger unit. Next, the plunger unit is inserted into the internal space 62 a above the louver shaft 60, and the respective shaft projections 75 a and 76 a formed at the closed ends of both plungers 75 and 76 are formed in the side surface of the louver shaft 60. The small opening 67 is fitted. Then, the tips of the shaft projections 75a and 76a of both plungers 75 and 76 are locked in a form that protrudes slightly outward from the small opening 67 of the louver shaft 60, and an inward force is applied to the tips of the shaft projections 75a and 76a. When working, the shaft protrusions 75a and 76a are retracted toward the internal space 62a, and return to the original position when the applied force is released.

  Further, as shown in FIGS. 11 and 12, a stopper member 78 on a flat plate is erected above the bulging portion 62 of the louver shaft 60. As shown in FIG. 9, the stopper member 78 extends to the center portion of the louver shaft 60. When the louver shaft 60 is assembled to the louver 50, the stopper member 78 comes into contact with a horizontal member 56 (see FIGS. 7 and 8) that hangs down from the upper surface portion 51 of the louver 50, thereby causing the louver 50 to be in a normal state. In addition to the standing state, the rotation of the louver 50 in one direction in which the long side surface 53 side of the louver 50 moves upward is allowed.

  The louver shaft 60 is attached to the louver 50 as follows. First, the above-described plunger unit is assembled in the internal space 62a of the louver shaft 60. Next, the straight portion 68 b of the louver shaft 60 is fitted between the vertical members 55 of the louver 50. The fitting direction is such that the stopper member 78 of the louver shaft 60 is on the long side surface portion 53 side of the louver 50.

Then, the shaft rod 69 is fitted into the shaft hole 58 formed in the vertical member 55. When the shaft rod 69 is fitted into the shaft hole 58, the vertically extended vertical member 55 returns to its original position, and the louver shaft 60 is rotatably attached to the louver 50 without rattling.

  After the shaft rod 69 is fitted into the shaft hole 58, when the louver shaft 60 is made vertical with respect to the louver 50, that is, when the louver 50 is in an upright state, the stopper member 78 of the louver shaft 60 is moved horizontally to the louver 50. The shaft protrusions 75a and 76a of the small-diameter plunger 75 and the large-diameter plunger 76 are fitted in the first engagement hole 59 provided on the vertical member 55 and positioned at the uppermost position on the right side of FIG. Match.

  In a state where the louver shaft 60 is engaged with a clamp shaft 80 or the like described later, the louver 50 is allowed to rotate only in the direction in which the long side surface portion 53 side moves upward. The rotation is performed between the three engagement holes 59. The angle is set every 22.5 °, and the movement between the engagement holes 59 is given a click feeling by the plunger spring 77 and is 0 ° (upright state), 22.5 °, Seesaw motion is performed in the range of 45 °. Then, the engagement with each engagement hole 59 prevents rotation with a slight force.

  In other words, the horizontal swinging rotation around the vertical axis of the louver 50 is automatically performed by the stepping motor 45 in an arbitrary angle range within 360 °, and the short side portion 52 and the long side portion 53 are separated from each other. The manual rotation in the vertical direction around the horizontal axis on the boundary center line is performed in the range of 0 °, 22.5 °, and 45 °.

  The clamp shaft 80 is a resin member. As shown in FIGS. 15 to 17, the clamp shaft 80 includes a horizontal intermediate wall 81 positioned in the middle, a skirt portion 82 hanging downward from the intermediate wall 81, and the intermediate wall 81. An outer cylindrical portion 83 standing upward and an inner cylindrical portion 84 standing upward from the intermediate wall 81 inside the outer cylindrical portion 83 are provided.

  A bearing member 100 (see FIGS. 22 to 24), which will be described later, is fitted in the skirt portion 82 with a margin, and a sliding surface is formed by the bottom surface of the intermediate wall 81 and the top surface of the bearing member 100. The outer diameter of the outer cylindrical portion 83 is slightly larger than the outer diameter of the skirt portion 82, and a mountain-shaped second gear 85 is formed on the upper end surface thereof. The second gear 85 is provided at the same pitch and on the same circumference as the first gear 70 formed in the internal space 61 a of the louver shaft 60, and the clamp shaft 80 is fitted in the internal space 61 a of the louver shaft 60. When combined, the first gear 70 is engaged, and the rotation by the stepping motor 45 is transmitted to the louver shaft 60 via the clamp shaft 80.

  A circumferential groove 88 (see FIG. 16) is formed on the outer periphery of the outer cylindrical portion 83. Since the outer diameter of the outer cylindrical portion 83 is longer than the distance from the straight portion 68 b of the spring 68, when the clamp shaft 80 is inserted into the inner space 61 a of the louver shaft 60, the outer cylindrical portion 83 is moved to the spring 68. Abuts against the inner surface. When the clamp shaft 80 is pushed in, the spring 68 is pushed and spread, and when the insertion of the clamp shaft 80 is completed, the spring 68 enters the circumferential groove 88 and returns to the original state, and the clamp shaft 80 Lock.

  As shown in FIG. 17, the inner cylindrical portion 84 has a D-shaped space 86 formed therein and a screw hole 87 provided on the upper surface thereof. Then, an intermediate transmission shaft 90 to be described later is inserted into the D-shaped space 86, and a screw 97 is inserted from above the screw hole 87, whereby the clamp shaft 80 and the intermediate transmission shaft 90 are fixed integrally.

The head portion 91 has a columnar shape and is formed with four longitudinal grooves 91a in the longitudinal direction and one cut groove 91b for engagement in order to reduce the weight, and has a substantially D-shaped cross section over the entire portion. A circular engagement disk 91c is formed in the part. The engaging disc 91c forms a slight gap with a flange portion 101 (see FIGS. 22 to 24) of the bearing member 100 described later, and the bearing is so described that the load when the louver 50 is attached / detached is described later. Let the member 100 escape.

  A screw hole 95 is formed on the upper surface of the head 91. The head 91 is fitted in the D-shaped space 86 of the clamp shaft 80 and is fixed by screws 97 (see FIG. 5). When the head 91 and the clamp shaft 80 are fixed by the screws 97, the intermediate transmission shaft 90 is lifted upward, and a gap is formed between the motor mounting base 40 and the upper wall surface 42a.

  The flange portion 92 is a circular portion having a larger diameter than the head portion 91, and abuts against the bottom surface of the flange portion 101 of the bearing member when the intermediate transmission shaft 90 is fitted to the bearing member 100 described later. The flange portion 92 and the flange portion 101 form a sliding surface. The column portion 93 is a portion that connects the head portion 91 and the flange portion 92, and a rectangular opening 96 that communicates with the screw hole 95 is formed through the bottom plate portion 94.

  The bottom plate portion 94 is a circular portion having a smaller diameter than the flange portion 92, and a rectangular opening 96 is formed at the center thereof. The bottom plate portion 94 is fitted and supported in a ring-shaped protrusion 42 c formed on the upper surface of the raised portion 42 of the motor mounting base 40. The motor shaft 45a of the stepping motor 45 is also rectangular, and when the bottom plate portion 94 is fitted into the ring-shaped protrusion 42c, the rectangular motor shaft 45a is inserted into the rectangular opening 96 formed in the bottom plate portion 94. This is done after insertion. The size of the rectangular opening 96 is larger than the size of the motor shaft 45a, and a large rattling is formed between the rectangular opening 96 and the motor shaft 45a. It does not act on the motor shaft 45a.

  The bearing member 100 is a resin member, and includes a flange portion 101 at the upper end portion, a cylindrical main body portion 102 below the flange portion 101, and a supporting bottom plate 103, as shown in FIGS. The flange portion 101 is formed so as to project inwardly on the upper surface of the cylindrical main body portion 102, and a fitting hole 104 is formed at the center thereof. A slight gap is formed between the flange inner surface 101a of the flange portion 101 and the engagement disc 91c formed on the head 91 of the intermediate transmission shaft 90, and the load when the louver 50 is attached / detached will be described later. To the bearing member 100.

  The support bottom plate 103 is a disk-shaped member projecting outward on the lower surface of the cylindrical main body 102, and the outer periphery thereof is formed with notch recesses 105 at three locations, and between the notch recesses 105, 3 Screw fixing holes 106 are provided. A plurality of reinforcing ribs 107 are provided at the boundary between the cylindrical main body 102 and the support bottom plate 103.

  The support bottom plate 103 is attached to the upper wall surface 42 a of the raised portion 42 of the motor mount 40. The attachment is performed by inserting the boss 44 formed on the upper wall surface 42a into the notch recess 105, inserting a screw (not shown) into the screw retaining hole 106 from above, and screwing the screw into the upper wall surface 42a. In a state where the support bottom plate 103 is attached to the upper wall surface 42 a of the motor mounting base 40, the ring-shaped protrusion 42 c formed on the upper wall surface 42 a is located in the cylindrical main body 102.

  The assembly of each member will be described. First, the louver shaft 60 is attached to the louver 50. The attachment is performed as follows. That is, the small diameter plunger 75 and the large diameter plunger 76 are assembled in the internal space 62 a of the louver shaft 60. Next, the straight portion 68 b of the louver shaft 60 is fitted between the vertical members 55 of the louver 50. The fitting direction is such that the stopper member 78 of the louver shaft 60 is on the long side surface portion 53 side of the louver 50.

  Specifically, a shaft rod 69 projects from the straight portion 68b. The shaft rod 69 is caught by the vertical member 55, and the fitting is not performed smoothly. Push in. Then, the shaft rod 69 is fitted into the shaft hole 58 formed in the vertical member 55. When the shaft rod 69 is fitted into the shaft hole 58, the vertically extended vertical member 55 returns to the original position, and the louver shaft 60 is attached to the louver 50 so as to be rotatable.

  Next, the bottom plate portion 94 of the intermediate transmission shaft 90 is supported in a ring-shaped protrusion 42 c formed on the upper surface of the raised portion 42 of the motor mount 40. At this time, a rectangular motor shaft 45a is inserted into a rectangular opening 96 formed in the bottom plate portion 94.

  Next, the bearing member 100 is attached from above the intermediate transmission shaft 90. The mounting is performed by inserting the head 91 of the intermediate transmission shaft 90 into the fitting hole 104 formed in the flange portion 101 of the bearing member 100, and then in the notch recess 105 formed in the support bottom plate 103 of the bearing member 100. The boss 44 of the upper wall surface 42a of the motor mounting base 40 is inserted into the motor mounting base 40, and the support bottom plate 103 is screwed to the upper wall surface 42a of the motor mounting base 40 with a screw (not shown).

  In a state in which the bearing member 100 is attached, the head 91 of the intermediate transmission shaft 90 protrudes upward from the flange portion 101 of the bearing member 100 and is formed on the inner surface 101a of the flange portion 101 and the head 91. The circular disc 91c is opposed to the circular disc 91c with a slight gap, performs a bearing action between both members, and supports the intermediate transmission shaft 90 so as to be rotatable. The bearing member 100 surrounds and protects the intermediate transmission shaft 90.

  Thereafter, the clamp shaft 80 is attached from above. For the attachment, the D-shaped head 91 of the intermediate transmission shaft 90 is inserted into the D-shaped space 86 of the clamp shaft 80, the screw 97 is inserted from above the screw hole 87, and the screw 97 is connected to the upper surface of the head 91. This is performed by screwing into a screw hole 95 formed in the above. As a result, the clamp shaft 80 is also rotated at the same time as the intermediate transmission shaft 90 is rotated.

  Thereafter, the louver shaft 60 already attached to the louver 50 is attached from above the clamp shaft 80. The attachment is performed by inserting the outer cylindrical portion 83 of the clamp shaft 80 into the inner space 61 a of the louver shaft 60. After the insertion, the spring 68 enters a circumferential groove 88 formed in the outer peripheral portion of the outer cylindrical portion 83, and the first gear 70 of the louver shaft 60 and the second gear 85 of the clamp shaft 80 are engaged. As a result, when the intermediate transmission shaft 90 is rotated, the clamp shaft 80 is rotated, and the louver shaft 60 and the louver 50 are rotated by the rotation of the clamp shaft 80.

  When the louver 50 is attached to the clamp shaft 80, the first gear 70 of the louver shaft 60 and the second gear 85 of the clamp shaft 80 are provided at the same pitch and on the same circumference. It can be mounted from any angle of 360 °.

  Next, the operation will be described. First, the opening angle of the louver 50 is set manually. The upper surface of the short side surface portion 52 of the louver 50 is pushed down. Then, the engagement between the shaft protrusions 75a and 76a of the small diameter plunger 75 and the large diameter plunger 76 and the first engagement hole 59 (the highest hole on the right side in FIG. 7) of the louver 50 is disengaged. The long side surface portion 53 is rotated about the horizontal axis at the boundary between the short side surface portion 52 and the long side surface portion 53, and the second engaging hole 59 (the central hole shown in FIG. When the shaft protrusions 75a and 76a of the plungers 75 and 76 are engaged with the second engagement hole 59, the louver 50 stops at an opening angle of 22.5 °.

  If the opening angle is acceptable, the operation proceeds to the next operation of rotating the louver 50 in the horizontal direction. However, if further opening is desired, the upper surface of the short side surface portion 52 of the louver 50 is subsequently pushed down. Then, the shaft protrusions 75a and 76a of both plungers 75 and 76 are disengaged from the second engagement hole 59 of the louver 50, and the long side surface portion 53 of the louver 50 moves upward about the horizontal axis. It further rotates in the form, proceeds to the third engagement hole 59 (the lowest hole on the left side shown in FIG. 7) with low resistance, and enters the third engagement hole 59 to the axial projection 75a of both plungers 75, 76. , 76a are engaged, the louver 50 stops at an opening angle of 45 °.

Thereafter, the switch on the operation unit 35 is turned on, and the louver 50 is rotated in the horizontal direction around the vertical axis. In the operation, as shown in FIG. 25, an arbitrary angle α can be set within a range of 360 ° by designating a start point S ₁ and an end point S ₂ during rotation (note that The control will be described later). When the angle is set, the stepping motor 45 swings at a specified angle, and the louver 50 swings and rotates at a specified angle. The rotation of the stepping motor 45 is transmitted to the louver 50 through the motor shaft 45a, the intermediate transmission shaft 90, the clamp shaft 80, and the louver shaft 60.

  Next, the operation unit 35 will be described with reference to FIG.

  The operation unit 35 includes an on / off switch 111, an off-timer switch 112, an operation switch 113, a rotation switch 114, a rotation angle setting switch 115, a clothing drying / room mold guard for instructing start and stop of the dehumidifier. Various switches X of the switch 116, LEDs 117, 118, and 119 for time display when the off timer is set (ie, 1 hour, 3 hours and 6 hours), operation status display (ie silent operation, medium operation and automatic operation) LED 120, 121, 122, 360 ° rotation display LED 123, spot display LED 124, rotation state display LED 125, rotation angle setting display LED 126, clothing drying selection display LED 127, room mold guard selection display LED128, ion generation display LED129, full water / tank LED130 for displaying, for the humidity display (40%, 60% and 80%) and various LED such LED131,132,133 the Y is provided.

  FIG. 27 is a block diagram of a control circuit in the dehumidifier according to the present embodiment. The control unit 134 includes a microprocessor, its peripheral circuits, motor and heater drive circuits, and the like. The control signals of the various switches X are input to the control unit 134, and the various types of LEDs Y are controlled to be turned on or off by the control unit 134. Further, the detection signal of the humidity sensor 135 and the detection signal of the position sensor 136 are input to the control unit 134. The position sensor 136 is a sensor that detects whether or not the louver 50 reciprocally swung by the blowing direction setting means is at the reference position. A detection signal from a float sensor 137 that detects the water level in the drain tank 31 is also input to the control unit 134.

  The mechanical parts that are driven and controlled by the output of the control unit 134 include the motor 24 of the main fan 23, the motor 26 of the dehumidification rotor 25, the motor of the regeneration fan 27d, the regeneration heater 27b, and the louver motor 45 that is a blowing direction rotation motor. , An ion generator 138. The microprocessor constituting the control unit 134 executes drive control of each mechanical component according to a program stored in the ROM and, if necessary, based on a detection signal of the humidity sensor 135 and a detection signal of the position sensor 136. To do.

Below, the various control in the dehumidifier concerning this Embodiment is demonstrated.
(1) Louver rotation angle range setting control I (see flowchart in FIG. 28)
If it is confirmed in step S1 that the louver 50 is being rotated, in step S2, when the rotation start point S ₁ (see FIG. 25) of the louver 50 is determined by turning on the rotation angle setting switch 115, in step S3. The rotation start point S ₁ is stored in the control unit 134, the rotation angle setting display LED 126 is blinked in step S4, and at the same time, the count of the number of steps N of the louver motor (stepping motor) 45 is started in step S5.

Next, when the user turns ON the rotation angle setting switch 115 in step S6 and the end point S ₂ (see FIG. 25) of the rotation angle range is determined, it is determined in step S7 whether N> 360 °. (In other words, it is determined whether or not the louver 50 has made one or more revolutions). If an affirmative determination is made here, the process returns to step S1 and the following control is repeated. If a negative determination is made, counting of the number of steps N of the louver motor (stepping motor) 45 is stopped in step S8. In step S9, the louver 50 starts swinging with the count number N. In step S10, the rotation angle setting display LED 126 is turned on, and then the process returns to step S1.

As described above, the start point S ₁ and the end point S ₂ of the rotation angle range of the louver 50 are arbitrarily determined according to the user's wishes by turning the rotation angle setting switch 115 twice. Therefore, the desired blowing direction of the dry air Wr ′ can be obtained without moving the dehumidifier itself. In addition, a desired rotation angle range in the middle of the rotation of the louver 50 can be set, and it is easy to adapt to the user's desire. Further, the start point S ₁ and the end point S ₂ of the rotation angle range of the louver 50 can be set only by operating the rotation angle setting switch 115 twice, and the rotation angle range can be easily set. Also. Even after the rotation start point S ₁ is determined, the rotation angle range can be set while observing the rotation state of the louver 50 since the rotation of the louver 50 is continued until the rotation end point S ₂ is determined. The rotation angle range can be reliably set.
(2) Louver rotation angle range setting control II (refer to the flowchart of FIG. 29)
If it is confirmed in step S1 that the louver 50 is being rotated, in step S2, when the rotation start point S ₁ (see FIG. 25) of the louver 50 is determined by turning on the rotation angle setting switch 115, in step S3. The rotation start point S ₁ is stored in the control unit 134, the rotation angle setting display LED 126 is blinked in step S4, and at the same time, the count of the number of steps N of the louver motor (stepping motor) 45 is started in step S5.

Next, when the user turns ON the rotation angle setting switch 115 in step S6 and the end point S ₂ (see FIG. 25) of the rotation angle range is determined, it is determined in step S7 whether N> 360 °. (In other words, it is determined whether or not the louver 50 has made one or more revolutions). If a negative determination is made here, the count of the step number N of the louver motor (stepping motor) 45 is stopped in step S8, the louver 50 starts swinging with the count number N in step S9, and rotates in step S10. The angle setting display LED 126 is turned on, and then the process returns to step S1. If an affirmative determination is made, the rotation angle setting state is canceled in step S11, and the rotation angle setting display LED 126 is blinked in step S12. Thereafter, the process returns to step S1.

As described above, in this case, when the count number N of the stepping motor 45 exceeds 360 ° (in other words, when the louver 50 makes one rotation or more), the rotation angle range is set again. It is. The other functions and effects are the same as in the case of (1), and the description is omitted.
(3) Louver rotation angle range setting control III (see flowchart in FIG. 30)
If it is confirmed in step S1 that the louver 50 is being rotated, in step S2, when the rotation start point S ₁ (see FIG. 25) of the louver 50 is determined by turning on the rotation angle setting switch 115, in step S3. The rotation start point S ₁ is stored in the control unit 134, the rotation angle setting display LED 126 is blinked in step S4, and at the same time, the count of the number of steps N of the louver motor (stepping motor) 45 is started in step S5.

Next, when the user turns ON the rotation angle setting switch 115 in step S6 and the end point S ₂ (see FIG. 25) of the rotation angle range is determined, it is determined in step S7 whether N> 360 °. (In other words, it is determined whether or not the louver 50 has made one or more revolutions). If a negative determination is made here, the count of the step number N of the louver motor (stepping motor) 45 is stopped in step S8, the louver 50 starts swinging with the count number N in step S9, and rotates in step S10. The angle setting display LED 126 is turned on, and then the process returns to step S1. However, if an affirmative determination is made, the count of the step number N of the louver motor (stepping motor) 45 is stopped in step S11, and the count number N in step S12. In step S10, the rotation angle setting display LED 126 is lit, and then the process returns to step S1. As described above, in this case, the count number N of the stepping motor 45 is started. 3 (In other words, if the louvers 50 has more than one revolution) if it exceeds 0 ° to it is has become a possible swing from the count number N in the rotation angle range minus 360 ° is initiated. The other functions and effects are the same as in the case of (1), and the description is omitted.

In the rotation angle range setting control, the start point S ₁ and the end point S ₂ are determined by turning on the rotation angle setting switch 115, but the start point S ₁ and the end point S ₂ are determined manually. May be.
(4) Louver operation control (refer to the flowchart in FIG. 31)
When the rotation switch 114 is turned on in step S1, it is determined in step S2 whether the louver 50 is rotating. If an affirmative determination is made here, the louver motor (stepping motor) 45 is stopped in step S3. Then, the process returns to step S1, but if a negative determination is made, it is determined in step S4 whether or not the previous rotation direction of the louver 50 is clockwise. If the determination is affirmative, the rotation is counterclockwise in step S5, and at the same time, the louver motor (stepping motor) 45 is started to rotate in step S6. On the other hand, if a negative determination is made in step S4, the rotation is clockwise in step S7, and at the same time, the louver motor (stepping motor) 45 is started to rotate in step S6.

As described above, the louver 50 is rotated in the direction opposite to the previous rotation direction every time the rotation switch 114 is turned on.
(5) Automatic operation control of dehumidifier (Refer to the flowchart of FIG. 32)
When automatic operation is selected by operating the operation changeover switch 113 in step S1, the regenerative heater 27b is turned on with high output, the louver motor 45 is turned on, the main fan motor 24 is turned on with "strong", and dehumidification is performed in step S2. The motor 26 is turned on, the regeneration fan 27d is turned on, and the ion generator 138 is turned on.

  Next, in step S3, it is determined whether 10 minutes have elapsed. This determination is performed to ensure the minimum operation time.

  Waiting for an affirmative determination in step S3, humidity data is taken into the control unit 134 in step S4, and it is determined in step S5 whether the humidity is ≧ 60%. If an affirmative determination is made here, the regeneration heater 27b is turned on at a high output in step S6, and the main fan motor 24 is turned on at "strong". If a negative determination is made in step S5, a determination is made in step S7 as to whether or not the humidity is ≧ 55%. If an affirmative determination is made here, the regenerative heater 27b is turned on with medium output in step S8, and the main fan motor. 24 is turned ON when “medium” is selected. Further, if a negative determination is made in step S7, a determination is made in step S9 as to whether or not the humidity is ≧ 53%. If an affirmative determination is made here, the regeneration heater 27b is turned on with a weak output in step S10, and the main fan motor 24 is turned on with “weak”. Furthermore, if a negative determination is made in step S9, the regenerative heater 27b is turned off in step S11, and the main fan motor 24 is turned on with "weak".

  That is, output control of the regenerative heater 27b and the main fan motor 24 is performed according to the humidity.

During the output control, it is determined in step S12 whether or not an off timer time (set by operating the off timer switch 112) has elapsed. If an affirmative determination is made here, the process proceeds to step S14. Then, the power is turned off and the operation ends. On the other hand, if a negative determination is made in step S12, it is determined whether or not 36 hours, which is the longest operation time of the dehumidifier, has been made in step S13. If a negative determination is made here, the process returns to step S4. If an affirmative determination is made, the power is turned off in step S14, and the operation ends.
(6) Clothes drying operation control of dehumidifier (Refer to the flowchart of FIG. 33)

The dehumidifying motor 26 is turned on, the regeneration fan 27d is turned on, and the ion generator 138 is turned on.

  Next, in step S3, it is determined whether or not 55 minutes have elapsed. This determination is performed to ensure the minimum operation time.

  Waiting for an affirmative determination in step S3, humidity data is taken into the control unit 134 in step S4, and in step S5, it is determined whether or not the humidity is <40%. In step S6, the output of the regeneration heater 27b is lowered to “medium”. That is, when the clothes to be dried become dry to some extent, the output of the regenerative heater 27b is lowered to “medium”.

  Next, in step S7, it is determined whether or not the humidity is greater than or equal to 35%. If a negative determination is made in this case, after driving for 3 minutes in step S8, the process proceeds to step S20, the power is turned off, and the operation ends. That is, when the humidity is <35%, it indicates that the clothes to be dried are dry, so the clothes drying control is terminated.

  On the other hand, if an affirmative determination is made in step S7, the time T taken between humidity = 40% and humidity = 35% is measured in step S9, and whether or not T ≧ 30 minutes is determined in step S10. If a positive determination is made here, the process proceeds to step S12, and the off timer is set to 120 minutes. If a negative determination is made in step S10, it is determined whether or not T ≧ 15 minutes in step S11. If an affirmative determination is made here, the process proceeds to step S13, and the off timer is set to 90 minutes. If a negative determination is made in step S11, the process proceeds to step S14, and the off timer is set to 60 minutes. Here, when T ≧ 30 minutes, the room is large and there is a lot of laundry (that is, clothes to be dried), and when 30 minutes> T ≧ 15 minutes, the room is medium and the laundry (that is, The case where the clothes to be dried is also medium is shown. When T <15 minutes, the room is small and the laundry is small, and the set time of the off-timer is selected corresponding to them.

  Then, in step S15, it is determined whether or not the off-timer has been subtracted to 0, and an affirmative determination is made here, and in step S16, it is determined whether or not humidity ≦ 30%. Here, if a negative determination is made, the off timer is set to 30 minutes in step S17. If an affirmative determination is made, the off timer is set to 15 minutes in step S18.

Thereafter, in step S19, it is determined whether or not 7 hours (the longest operating time of the dehumidifier) has elapsed since the start. Here, after affirmative determination is made, the power is turned off in step S20 and the operation is started. finish.
(7) Room mold guard operation control of the dehumidifier (refer to the flowchart in FIG. 34)
If the mold guard operation is selected by operating the clothes drying / room mold guard switch 116 in step S1, the regeneration heater 27b is turned on with high output, the louver motor 45 is turned on, and the main fan motor 24 is "strong" in step S2. The dehumidifying motor 26 is turned on, the regeneration fan 27d is turned on, and the ion generator 138 is turned on.

  Next, in step S3, it is determined whether 10 minutes have elapsed. This determination is performed to ensure the minimum operation time.

  Waiting for an affirmative determination in step S3, the humidity data is taken into the control unit 134 in step S4, and it is determined in step S5 whether or not the humidity is ≦ 50%. In step S6, the output of the regenerative heater 27b is lowered to “low”.

  Next, in step S7, the humidity data is again taken into the control unit 134. In step S8, it is determined whether or not the humidity is ≦ 45%. If the determination is negative, the regeneration heater 27b is determined in step S9. Although the output is maintained at “low”, if an affirmative determination is made, the regeneration heater 27b is turned off in step S10.

  Thereafter, in step S11, it is determined whether or not an off-timer time (set by operating the off-timer switch 112 by the user) has elapsed. If an affirmative determination is made here, the process proceeds to step S13, and the power is turned off. And the operation ends. On the other hand, if a negative determination is made in step S11, it is determined in step S12 whether or not 36 hours, which is the longest operation time of the dehumidifier, has passed. If a negative determination is made here, the process returns to step S7. If an affirmative determination is made, the power is turned off in step S13, and the operation ends.

In the above embodiment, the louver 50 has a structure that swings up and down around the horizontal axis. However, as will be described in the following modification, the louver 50 is rotated with the rotation of the louver 50 around the vertical axis.
