[appearance]
1 to 4 are external views showing a dehumidifier according to the present embodiment. FIG. 1 is a plan view, FIG. 2 is a front view, FIG. 3 is a right side view, and FIG. As shown in FIGS. 1 to 4, this dehumidifier is a dehumidifier with a circulator that can also be used for drying washed clothes, and has a box shape of a blower unit 20 on a box-shaped casing 10 </ b> C of the dehumidification unit 10. It has a structure in which a casing 20C is placed.

  Although details will be described later, the dehumidifying unit 10 includes a dehumidifying unit 12 (see FIG. 7) that dehumidifies the air sucked from the suction port 11, and blows out the dehumidified air dehumidified by the dehumidifying unit 12 from the air outlet 13. . The blower outlet 13 is an opening formed on the upper surface of the dehumidifying unit 10 (see FIG. 12). The blower unit 20 includes a blower 21 such as a circulator that blows dehumidified air blown from the blower outlet 13, and a holding part 22 that holds the blower 21. The holding unit 22 of the blower unit 20 is formed with a dehumidified air guiding air passage 23 that guides the dehumidified air blown from the blower outlet 13 of the dehumidifying unit 10 to the blower unit 21. The holding part 22 is provided so as to cover the air outlet 13 formed on the upper surface of the dehumidifying unit 10, and the lower part of the holding part 22 is close to the upper part of the dehumidifying unit 10. As a result, the gap between the dehumidifying unit 10 and the blower unit 20 becomes narrow, and there is no step between the dehumidifying unit 10 and the blower unit 20 and it becomes flat.

  According to such a configuration, the entire air outlet 13 of the dehumidifying unit 10 is covered by the air blowing unit 20 from above, so that the dehumidified air is hardly escaped through the dehumidified air guiding air passage 23 and dried to an object to be dried such as clothing. It can be blown toward. In addition, dust / dust is difficult to collect between the dehumidifying unit 10 and the blower unit 20, and it is possible to prevent dust / dust from entering the dehumidifying unit 10.

  Hereinafter, the stationary posture shown in FIGS. 1 to 4 is referred to as a “reference posture”. That is, the “reference posture” is a posture in which the air blowing port of the air blowing unit 21 faces directly upward with the air blowing unit 20 facing the front. In such a reference posture, since the blower part 21 is formed so as not to protrude from the holding part 22, it is possible to prevent the blower part 21 from being damaged even if it falls down. It is.

  On the other hand, the air blowing unit 21 is supported in the holding unit 22, and the air blowing unit 21 is pivotally attached to the holding unit 22 so as to be rotatable about a horizontal axis. Further, the blower unit 20 is pivotally attached to the dehumidifying unit 10 so as to be rotatable around a vertical axis. Thereby, the wind direction can be adjusted in an arbitrary direction as shown in FIG.

  Further, a touch panel type operation unit P is provided on the top surface or the back surface of the holding unit 22 of the blower unit 20. The operation unit P may be provided across both the top surface and the back surface of the holding unit 22.

The resistive film method is a method of detecting the position of the panel touched by a finger by measuring a voltage change. The electrostatic capacitance type is a method of detecting a position using electrical capacitive coupling generated when a finger touches the panel. The operation unit P is not limited to such a touch panel, and for example, a tact switch may be used. The operation unit P includes a swing button, a circulator button, a dehumidifying button, a timer button, an operation button (off / on), and the like. When the operation unit P is operated, the operation content is notified to a control unit which will be described later, and various controls are executed. According to such an operation unit P, the user can easily operate from the back side with a light force without going around to the front side of the dehumidifier.

[Wind direction adjustment]
FIG. 5 is an explanatory diagram of wind direction adjustment of the dehumidifier according to the present embodiment. As described below, by swinging in the vertical direction and the horizontal direction, the blowing direction of the dehumidified air by the blowing unit 21 can be freely adjusted.

  Specifically, FIG. 5A shows a state in which the air blowing unit 21 swings 45 degrees forward and backward from the reference posture at 45 degrees. FIG. 5B shows a state in which the blower unit 21 swings 90 degrees forward and backward from the reference posture. FIG. 5C shows a state in which the blower unit 20 swings its head to the right from the reference posture, and the blower unit 21 swings its head 45 degrees forward.

  That is, as shown in FIGS. 5A and 5B, the air blowing unit 21 is provided so as to be swingable up and down with respect to the holding unit 22. The vertical swing can be manually performed in a range of 90 degrees from upward to forward. On the other hand, as shown in FIG. 5C, the holding unit 22 of the blower unit 20 is provided so as to be swingable left and right with respect to the dehumidifying unit 10. The left / right swing can be adjusted in three stages of, for example, 50 degrees, 70 degrees, and 90 degrees by automatic control. The term “50 degrees” used for swinging left and right is an angle of 25 degrees left and right with reference to the front. 70 degrees in terms of swinging left and right is an angle of 35 degrees left and right with respect to the front. 90 degrees in terms of swinging left and right is an angle of 45 degrees left and right with respect to the front. As described above, the dehumidifier according to the present embodiment is configured to swing freely in the vertical direction and the horizontal direction.

[Example of use]
FIG. 6 is an explanatory diagram of a usage example of the dehumidifier according to the present embodiment. Here, the case where it utilizes for the drying of the laundry 100 dried indoors is illustrated. As shown in this figure, by using dehumidified low-humidity air (dehumidified air) for blowing air, the dehumidified air is directly applied to the laundry 100 to promote drying of the laundry 100 and shorten the drying time. be able to.

  Moreover, the holding unit 22 is provided so as to cover the air outlet 13 formed on the upper surface of the dehumidifying unit 10 so that the lower part of the holding unit 22 is close to the upper part of the dehumidifying unit 10. As a result, the gap between the dehumidifying unit 10 and the blower unit 20 becomes narrow, and there is no step between the dehumidifying unit 10 and the blower unit 20 and it becomes flat. According to such a configuration, since the dehumidified air can be blown toward the laundry 100 with almost no escape, the drying time can be shortened as compared with the conventional case.

  In addition, since the vertical and horizontal swing angles can be freely adjusted according to the indoor drying scene, the laundry 100 that has been dried in a high position or the laundry 100 that has been widely dried It is possible to efficiently apply dehumidified air. Further, the dehumidified air is blown toward the laundry 100 from the front side of the dehumidifier, but since the operation unit P is provided on the top surface or the back surface of the holding unit 22 of the blower unit 20, the dehumidifier air is easily provided from the back side of the dehumidifier. It can be operated and is easy to use.

  Further, a box-shaped air blowing unit 20 is provided on the upper portion of the box-shaped dehumidifying unit 10 so as to freely swing, and the dehumidifying unit 10 and the air blowing unit 20 are continuous with each other in the standard posture shown in FIGS. It is formed to be a box shape. As already described, the “reference posture” is a posture in which the blower unit 21 faces the front and the blower port of the blower unit 21 faces directly upward (see FIGS. 1 to 4). “The state in which the blower unit 20 faces the front” is a state in which the vertical swing shaft of the blower unit 21 is disposed in the left-right direction. Further, the “integral box shape with continuity” means a box shape having a sense of unity in appearance. It can also be said to be a box shape in which at least one surface is substantially flush (planar and flat) in a plan view. The “box shape” is typically a rectangular parallelepiped, but is not limited to a rectangular shape in plan view, and includes a circular shape, a half-moon shape, a kamaboko shape, and the like. In addition, the front and side views have a “flying box shape” in which the width dimension gradually increases from the upper end to the lower end, and the shape in which the width dimension increases from the upper end to the upper and lower middle part and the width dimension is constant from the intermediate part to the lower end ( It may be a shape in which a quadrangular pyramid is placed on a rectangular parallelepiped), or a barrel shape in which the width dimension increases from the upper end to the upper and lower intermediate part and the width dimension decreases from the intermediate part to the lower end.

  According to such a structure, it becomes an integral box shape with a standard posture, and it looks clear. That is, since the dehumidifying unit 10 and the air blowing unit 20 have a design with a sense of unity in appearance, a fashionable feeling can be improved and interior characteristics can be enhanced.

FIG. 7 is an exploded perspective view of the dehumidifying unit 10 provided in the dehumidifier according to the present embodiment. As shown in this figure, the dehumidifying unit 10 has a dehumidifying unit 12 that dehumidifies the air sucked from the suction port 11. The dehumidified air dehumidified by the dehumidifying unit 12 is blown upward from an air outlet 13 (see FIG. 12) formed on the upper surface of the dehumidifying unit 10. These units are controlled by the main control board 16. A blower unit 20 independent of the suction fan 14 is mounted on the upper portion of the dehumidifying unit 10. The internal structure of the blower unit 20 will be described later.

  The dehumidifying unit 12 employs a desiccant method as a dehumidifying method, and includes a duct 12A, a heater 12B, a dehumidifying rotor 12C, a heat exchanger 12D, a tank, and the like. That is, when moist air passes through the dehumidification rotor 12C, moisture is adsorbed to the dehumidification rotor 12C. When the dehumidification rotor 12C rotates and the portion where moisture is adsorbed is heated by the heater 12B, the adsorbed moisture becomes water vapor. The water vapor is cooled by room air in the heat exchanger 12D, condensed, and turned into water. The water flows down to the tank 12E and is stored. The dehumidification rotor 12C dried by the heater 12B adsorbs moisture again. Of course, the dehumidification method is not limited to the desiccant method, and a compressor method, a hybrid method, or the like can also be adopted.

[Blower unit]
FIG. 8 is an exploded perspective view of the blower unit 20 provided in the dehumidifier according to the present embodiment. Here, the air blower 21 is removed from the holding unit 22 and the cover covering the holding unit 22 is removed.

And it forms so that the ventilation part 21 may be hold | maintained in opening part 22D formed by the side wall part 22B and the rear wall part 22C.

  The opening 22D only needs to be released at least forward. Further, the side wall portion 22B only needs to be erected on at least one of the left and right side portions of the bottom wall portion 22A.

  On the other hand, the blower unit 21 includes a box-shaped housing 21H having a bottom surface 21A formed in a substantially arc shape, and a shaft 21B extends from the left and right side surfaces of the housing 21H. It is desirable that a spiral panel 21P for generating a spiral airflow is attached to the upper air blowing port. Spiral airflow goes straight in a vortex and reliably reaches laundry that is dried a little far away. When the air blower 21 is placed in the opening 22D and the shaft 21B of the air blower 21 is placed in the U-shaped recess 22B1, most of the air blower 21 is covered with the holding part 22. According to such a configuration, not only the effect of preventing the blower 21 from being damaged at the time of falling but also the effect of preventing the finger from being caught. The spiral panel 21P includes a plurality of curved fins provided so as to form a spiral-shaped gap.

  The blower unit 20 includes a control unit 25. The control unit 25 includes power ON / OFF (dehumidification unit as a dehumidifier or operation of the blower unit 21), rotation speed of the blower fan 21F (see FIG. 9), left / right swing operation / angle, timer, ion generator 26 etc. are controlled. Here, the control part 25 is arrange | positioned at the holding | maintenance part 22 (the back side of the operation part P). When the power supply of the dehumidifying unit 10 is turned off, or when the blowing of the blowing unit 21 is stopped, or when the left / right swing is turned off, the control unit 25 swings the left / right swinging position. Is returned to the reference posture (described later). According to such a configuration, since it stands by in the reference posture when not in use, it is possible to maintain a sense of unity of appearance.

  Although detailed illustration is omitted, the control unit 25 is a control board composed of a plurality of hardware such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). Are connected to each part on the side, the main control board 16 on the dehumidifying unit 10 side, and the like. A control program is stored in the ROM of the control unit 25, and various controls are realized by the CPU executing the control program.

  The blower unit 20 may include an ion generator 26 that generates ions. According to such a configuration, since ions can be released together with dehumidified air, an antibacterial effect of a dry object such as clothing can be obtained.

[Air path for dehumidifying air guidance]
FIG. 9 is an explanatory diagram of the dehumidified air guiding air passage 23 provided in the dehumidifier according to the present embodiment. Here, for convenience of explanation, only main components inside the blower unit 20 are shown.

  As shown in this figure, the bottom wall portion 22A of the holding portion 22 is formed with a first ventilation port 22A1 communicating in the vertical direction. The first vent 22A1 is a large number of windows (gap) formed over almost the entire surface of the bottom wall 22A. Regardless of the direction in which the blower unit 20 swings in the left-right direction, the first vent 22A1 is connected to the dehumidifying unit 10 so that the numerous first vents 22A1 of the bottom wall portion 22A correspond to the outlets 13 of the dehumidifying unit 10. It is formed in a wider range than the air outlet 13. The dehumidified air blown from the outlet 13 of the dehumidifying unit 10 is guided to the blower fan 21F of the blower unit 21 through the first vent 22A1 that forms part of the dehumidified air guiding air passage 23. Since the first ventilation port 22A1 is partitioned by thin ribs and has low ventilation resistance, the first ventilation port 22A1 can be guided to the blower fan 21F of the blower unit 21 without reducing the air volume of the dehumidified air blown from the blower outlet 13 of the dehumidification unit 10. it can.

  Further, the rear wall portion 22C is formed with a second ventilation port 22C1 communicating in the front-rear direction. The second vent 22C1 is a large number of windows (gap) formed over substantially the entire surface of the rear wall 22C. Regardless of the direction in which the air blower 21 swings in the vertical direction, the numerous first vents 22A1 of the bottom wall 22A and the second vents 22C1 of the rear wall 22C are almost the entire bottom surface 21A of the blower 21. It is comprised so as to correspond to the suction port 21A1. Thereby, a sufficient amount of outside air can be taken in from the rear side of the blower unit 20 through the second vent 22C1.

  The holding portion 22 includes side wall portions 22B on the left and right sides, and a rear wall portion 22C on the rear side. Therefore, the holding portion 22 has a U-shape in plan view at the side wall portion 22B and the rear wall portion 22C, and the entire amount of the dehumidified air can be blown without escaping, so that sufficient dehumidifying performance can be ensured. In addition, not only dehumidified air is taken in from the first vent 22A1 formed in the bottom wall portion 22A but also outside air is taken in from the second vent 22C1 formed in the rear wall portion 22C. It is possible to ensure a sufficient amount of air supplied to the fan 21F.

  In addition, an air suction port 21A1 is formed on the substantially arc-shaped bottom surface 21A of the blower portion 21 over substantially the entire surface. Regardless of the direction in which the blower portion 21 swings in the vertical direction, the substantially arc-shaped bottom surface 21A and the first vent 22A1 of the bottom wall portion 22A maintain a constant distance. In addition, since the air suction port 21A1 is formed at any position on the substantially arc-shaped bottom surface 21A, the first ventilation port of the bottom wall portion 22A no matter which direction the blower unit 21 swings in the vertical direction. The suction port 21A1 corresponds to (opposites) 22A1, and the dehumidified air from the dehumidifying unit 10 can be efficiently sucked from the suction port 21A1.

  The blower fan 21F is a propeller fan that generates an air flow. The air flow generated by the propeller fan is turned into a spiral air flow by the spiral panel 21P so as to reach far. Therefore, drying can be promoted even in a use environment where the dehumidifier cannot be arranged near the laundry. In addition, although illustration is abbreviate | omitted, the ventilation part 21 may have the front panel in which the radial fin was formed. Moreover, the ventilation part 21 may have a sirocco fan and a cross flow fan.

[Pivot structure of shaft of air blower]
FIG. 10 is an explanatory view of a pivot structure that pivotally supports the shaft 21B of the air blowing unit 21 provided in the dehumidifier according to the present embodiment. As already described, the U-shaped recess 22B1 for the bearing is formed in the side wall portion 22B of the holding portion 22. The shaft 21B of the blower portion 21 is placed in the U-shaped recess 22B1, and is restrained by the restraining plate 22B2 from above. As a result, the shaft 21B of the blower portion 21 can be pivotally supported by the U-shaped concave portion 22B1 and the restraining plate 22B2, so that it is possible to prevent rattling of the vertical swing. Also, with such a pivot structure, assembly becomes easy, so that the work efficiency of the assembly can be improved.

  Here, on the surface of the shaft 21 </ b> B of the blower unit 21, a plurality of locking recesses 21 </ b> B <b> 1 are formed at predetermined intervals along the rotation direction. It corresponds to a range of 90 degrees. On the other hand, the lower end portion of the holding plate 22B2 is formed in a substantially arc shape in accordance with the diameter of the shaft 21B of the blower portion 21, and the spring 22B3 and the convex portion 22B4 are inserted into a hole formed in the center of the lower end portion. Accordingly, when the user holds the blower 21 and moves it up and down, the convex portion 22B4 moves over the locking concave portion 21B1. At this time, since the protrusion 22B4 is always pressed in the direction of the shaft 21B of the blower 21 by the spring 22B3, the protrusion 22B4 can be locked to the locking recess 21B1 with an appropriate strength.

[Connection between blower unit and dehumidifying unit]
FIG. 11 is a bottom perspective view of the blower unit 20 provided in the dehumidifier according to the present embodiment. As shown in this figure, the blower unit 20 includes a stepping motor 31 as a drive source for swinging left and right. The stepping motor 31 is a synchronous motor that operates in synchronization with pulse power. The use of the stepping motor 31 not only facilitates precise control of the air flow in the left-right direction, but also reduces the number of components (that is, eliminates the need for a link mechanism that has been necessary in the past) and the compact rotation mechanism. There is an effect of making. The control unit 25 provided in the blower unit 20 allows the rotation angle of the stepping motor 31 to be set electrically. In other words, the control unit 25 sets the angle of the left and right swing of the blower unit 20 to the user (user). It is configured so that it can be changed according to setting input by operation.

  Specifically, as shown in FIG. 11, a first vent 22A1 is formed in the bottom wall portion 22A, and a fixing plate 32 is disposed behind the first vent 22A1. A stepping motor 31, a left / right swinging shaft 33, and origin detection means 34 are fixed to the fixed plate 32. The left / right swing shaft 33 is a left / right swing axis of rotation. The origin detection means 34 is composed of an IR (infrared) sensor (for example, a phototransistor or the like). The origin detection means 34 may be composed of a magnet and a magnetic sensor.

  As shown in FIG. 11, the blower unit 20 includes a left and right swing shaft 33 and swing guide portions 35A, 35B, and 35C that are provided around the left and right swing shaft 33 and guide the left and right swing.

According to such a configuration, since the left and right swings are guided along the swing guide portions 35A, 35B, and 35C, it is possible to prevent rattling during the left and right swings.

  FIG. 12 is a top perspective view of the dehumidifying unit 10 provided in the dehumidifier according to the present embodiment. As shown in this figure, a blower outlet 13 is formed on the upper surface of the dehumidifying unit 10, a fixed gear 41 is disposed behind the blower outlet 13, and a circle around the rotation axis is provided so as to surround the rear of the fixed gear 41. An arc-shaped guide slit 42 is formed, and a roller traveling portion 43 is formed so as to surround the air outlet 13 and the guide slit 42. Further, a hole 41A is formed in the central portion of the fixed gear 41, and a left and right swing shaft 33 on the air blowing unit 20 side is attached to the hole 41A. Further, on the upper surface of the dehumidifying unit 10, a convex light shielding plate 44 that shields the origin detection means (IR sensor) 34 is formed. When light is shielded by the light shielding plate 44, the origin detection means (IR sensor) 34 detects the origin of the left and right swing. In the present invention, the origin of the left and right swing indicates the reference posture in which the blower unit 20 faces the front.

  13 to 15 are perspective views showing the positional relationship between the dehumidifying unit 10 and the blower unit 20 when the dehumidifier according to the present embodiment is performing a left-right swing operation. In these drawings, only main components on the upper surface of the dehumidifying unit 10 and the bottom surface of the blower unit 20 are shown.

  First, as shown in FIG. 13, in the reference posture, the origin detection means (IR sensor) 34 is shielded by the light shielding plate 44, and the dehumidifying unit 10 and the blower unit 20 are formed into an integral box shape having continuity. Yes. In this state, when the user instructs to swing left and right using the operation unit P, the instruction signal is notified to the control unit 25, and the control unit 25 drives the stepping motor 31. Thereby, the gear 31G connected to the stepping motor 31 rotates and moves around the fixed gear 41 fixed to the dehumidifying unit 10 side, and the blower unit 20 turns in the left-right direction with respect to the dehumidifying unit 10. Here, in the left maximum turning state (when viewed from the user standing on the back side of the dehumidifier, the right maximum turning state), as shown in FIG. It will be in a state tilted. On the other hand, in the maximum right turning state (the maximum left turning state when viewed from the user standing on the back side of the dehumidifier), the blower unit 20 is 45 degrees to the right with respect to the dehumidifying unit 10 as shown in FIG. It will be tilted. The blower unit 20 covers the entire outlet 13 of the dehumidifying unit 10 from above in both the left maximum turning state and the right maximum turning state (see FIGS. 14 and 15). Therefore, it is possible to guide the dehumidified air blown out from the air outlet 13 to the blower unit 21 through the dehumidified air guiding air passage 23 with almost no escape.

  Note that swing guide portions 35 </ b> A, 35 </ b> B, and 35 </ b> C are formed downward from the blower unit 20. The tip of the swing guide part 35 </ b> A is formed in a hook shape and is hooked in a groove formed in the opening of the air outlet 13. Further, a washer is provided at the tip of the swing guide portions 35B and 35C so as not to come out of the guide slit 42. Further, since the swing guide portions 35A, 35B, and 35C are configured to turn only within a certain range corresponding to the maximum angle of the left and right swings, the swinging guide portions 35A, 35B, and 35C are also regulated for the left and right swing angles.

  Further, leg portions 36A, 36B, 36C, 36D are formed downward from the blower unit 20. A roller is attached to the tip of the leg portions 36 </ b> A, 36 </ b> B, 36 </ b> C, 36 </ b> D, and this roller is in contact with the roller running portion 43. According to such a configuration, the roller travels on the roller travel unit 43 during the left and right swing operation. As a result, since the weight of the blower unit 20 can be received not only by the left and right swing shaft 33 but also by the legs 36A, 36B, 36C, and 36D, it becomes possible to further prevent backlash during the left and right swing. .

[Home return operation]
FIG. 16 is a flowchart showing the operation of the dehumidifier according to the present embodiment. Here, attention is paid to the origin return operation of left and right swinging, and description of other operations is omitted. The home position means a reference posture (origin) in which the blower unit 20 faces the front.

  First, when the power is turned on, the control unit 25 determines whether or not there is a circulator setting (specifically, a setting input for operating the blower unit 21) when in the home position (steps S1 → S2). → S3).

  Next, if there is a setting of the circulator, the control unit 25 operates the circulator (blower unit 21) based on the setting content (steps S3 → S4). If there is a setting for swinging left and right (specifically, a setting input for swinging the blower unit 20 in the left-right direction), the swinging of the blower unit 20 is operated based on the setting content (step S5 → S6).

  The left and right swing angles (90 degrees, 70 degrees, 50 degrees) of the blower unit 20 are controlled by the number of steps of the stepping motor 31. For example, when the angle of the left and right swing of the blower unit 20 is set to 90 degrees, the control unit 25 causes the neck so that the blower unit 20 rotates within an angle range of 45 degrees right and 45 degrees with respect to the origin. A swing pulse signal is applied. During the left / right swing operation, the home position is detected by the origin detection means 34 every time, and the left / right swing angle of the blower unit 20 is adjusted by the number of steps from the home position. Thereby, the number of steps can be corrected every time the home position is passed. Therefore, even when the blower unit 20 hits an object in the middle of the left / right swing, it is possible to continue the left / right swing operation with the correct number of steps.

  If the home position is not detected by the origin detection means 34 even if it moves 45 degrees after the planned home position detection position arrives, it is determined that the swinging operation is abnormal (IR sensor abnormality). The planned home position detection position is a planned position where the home position is detected by the origin detection means 34. In the case of an abnormal swinging operation, it is preferable not to use the origin detection means 34 and to perform control only by the number of steps of the stepping motor 31.

  Subsequently, the control part 25 will perform home position movement control, if the ventilation of a circulator (blower part 21) is stopped (step S7-> S8). The home position movement control is control for moving (returning) the left / right swing position to the home position. For example, each time the user presses a circulator button included in the operation unit P, the strength setting of the blowing unit 21 may be switched in the order of strong → medium → weak → stop. When the circulator (air blowing unit 21) stops blowing, the pulse signal of the shortest distance from the current state to the home position is applied to the stepping motor 31 to return to the reference posture.

  Further, when the left / right swing is turned off, the control unit 25 performs home position movement control (steps S9 → S10). For example, each time the user presses the swing button included in the operation unit P, the angle setting of the left and right swing may be switched in the order of 90 degrees → 70 degrees → 50 degrees → off. When the left / right swing is turned off, a pulse signal of the shortest distance from the current state to the home position is applied to the stepping motor 31 to return to the reference posture.

  Moreover, the control part 25 will perform home position movement control, if the power supply of the dehumidification unit 10 is turned off (step S11-> S12). For example, each time the user presses the operation button (OFF / ON) included in the operation unit P, the power supply may be turned on / off. When the power is turned off, a pulse signal of the shortest distance from the current state to the home position is applied to the stepping motor 31 to return to the reference posture.

  If the user does not turn off the power using the operation button (off / on) included in the operation unit P, and the power is cut off by unplugging the power cord from the outlet, the posture remains in the middle of swinging left and right. It becomes. Therefore, when the power is turned on next time, if it is not in the home position (reference posture), the head is swung until the origin is detected by the origin detection means 34, and stopped at the position where the origin is detected and returned to the reference posture. (Steps S1-> S2-> S13).

  Further, when there is a home position shift instruction (left / right swing off, air blowing stop of the air blowing unit 21 or power off of the dehumidifying unit 10) during the left / right swing operation, the movement toward the home position is performed immediately. However, if there is an instruction to move to the home position near the home position (near the detection position of the origin detection means 34), the head is once swung 50 degrees and then stopped at the home position. Thereby, it can be surely stopped at the home position regardless of the timing when the home position shift instruction is given.

  As described above, the dehumidifier according to the present embodiment has the dehumidifying unit 12 that dehumidifies the air sucked from the suction port 11, and dehumidifies the dehumidified air dehumidified by the dehumidifying unit 12 from the air outlet 13.
