  Hereinafter, embodiments will be described with reference to the drawings. In the description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

  In addition, the embodiments described below exemplify apparatuses and methods for embodying the technical idea, and do not specify the material, shape, structure, arrangement, etc. of the component parts as follows. . This embodiment can be variously modified based on the description of the scope of claims.

  Referring to FIGS. 1 and 2, an air conditioner according to the present embodiment is generally indicated by reference numeral 10. The air conditioning apparatus 10 according to the present embodiment includes an air conditioning unit 12 for adjusting indoor air, and a blower unit 14 for sending out air (adjusted air) adjusted by the air conditioning unit 12 into the room.

  As shown in FIG. 4, the air conditioning unit 12 includes an air adjustment unit 22 that adjusts at least one of air temperature, humidity, and cleanness, and a first suction port 44 that adjusts air adjusted by the air adjustment unit. And a first air blowing part 23 for discharging from the first air outlet 50. In the air conditioning unit 12, an air adjusting unit 22 and a first air blowing unit 23 are accommodated in a box-shaped housing 20.

  As shown in FIG.1 and FIG.2, the ventilation unit 14 is equipped with the 2nd ventilation part 24 which attracts | sucks and blows off the adjustment air adjusted with the air conditioning unit, and the holding frame 26 holding a 2nd ventilation part. ing.

  The second air blower 24 includes a housing 28 and a blower fan 29 (see FIG. 2) that is housed in the housing 28 and is driven to rotate. The blower fan 29 may be, for example, a propeller fan, or a sirocco fan or a cross flow fan (not shown). The housing 28 surrounds the radially outer side of the blower fan 29 at the side wall portion. That is, an air tunnel is formed by the side wall of the housing 28, and there is an advantage that the straightness of the air flow generated by the blower fan 29 is improved. The second air blowing unit 24 includes a second suction port 28 a that sucks the adjusted air discharged from the air conditioning unit 12 into the housing 28, and the adjusted air sucked into the housing 28 into a room that is outside the housing 28. It has the 2nd blower outlet 28b which blows off. The spiral panel 31 is provided in the 2nd blower outlet 28b. The swirl panel 31 turns the air flow generated by the blower fan 29 into a spiral airflow, and this spiral airflow travels straight while spirally swirling so that the adjusted air released from the air conditioning unit 12 reaches further away. There is an advantage that can be. The second air blower 24 is further held (pivoted) by the holding frame 26 so as to be rotatable around a horizontal axis Lh (see FIG. 1). That is, the 2nd ventilation part 24 is comprised so that a swing is possible to an up-down direction.

  The air blowing unit 14 is supported so as to be rotatable about the vertical axis Lv (see FIGS. 1 and 2) with respect to the air conditioning unit 12. That is, the blower unit 14 is configured to swing freely in the left-right direction.

  The air conditioning unit 12 and the air blowing unit 14 are in a swinging reference posture (the air blowing unit 14 is in the state shown in FIGS. 1 and 2 facing the front, and the second air outlet 28b is facing directly above. When the air-conditioning unit 12 is in a stationary posture, the air-conditioning unit 12 is formed so as to have a continuous box-like shape in which the air blowing unit 14 is placed on the air-conditioning unit 12. In the reference posture, the gap between the air conditioning unit 12 and the air blowing unit 14 is narrow, and there is no level difference between the air conditioning unit 12 and the air blowing unit 14, so that dust and dirt are less likely to enter the air conditioning unit 12. .

  The air conditioning unit 12 has an air intake 30 on the back surface 20b of the housing 20, and an air delivery port 32 (see FIG. 10) for sending out the air adjusted by the internal air conditioning unit 12 to the outside of the housing 20. ) Is provided in an open shape on the upper surface (top surface) 20c.

  As shown in FIGS. 1 and 13, the blower unit 14 is formed with a vent hole 27 communicating with the bottom wall portion of the holding frame 26 in the vertical direction. The vent 27 is a large number of windows (gap) formed over substantially the entire bottom wall. Regardless of the direction in which the blower unit 14 swings in the left-right direction, the air vents 27 are located in the air conditioning unit 12 so that the air vents 27 on the bottom wall portion correspond to the air outlets 32 of the air conditioning unit 12. It is formed in a wider range than the delivery port 32. The holding frame 26 of the blower unit 14 includes side wall portions 26a and 26b on both the left and right sides, and a rear wall portion 26c on the rear side. Therefore, the holding frame 26 is U-shaped in plan view with the left and right side wall portions 26a, 26b and the rear wall portion 26c, and the entire amount can be blown without escaping the adjustment air, so that sufficient dehumidification performance can be ensured. is there. Further, not only the adjustment air is taken in from the vent 27 formed in the bottom wall portion, but also the outside air is taken in from the vent 33 formed in the rear wall portion 26c, so that the amount of air supplied to the second blower portion 24 is reduced. It is possible to ensure enough. In addition, a suction port is formed on the substantially arc-shaped bottom surface of the second air blowing unit 24 over substantially the entire surface. Regardless of the direction in which the second air blower 24 swings in the vertical direction, the substantially arc-shaped bottom surface and the vent 27 on the bottom wall part maintain a constant distance.

  As shown in FIGS. 1 and 10, the air conditioner 10 of the present embodiment is provided with a guide air passage 45 that guides the adjusted air discharged from the air conditioning unit 12 to the second suction port 28 a of the second blower 24. ing.

With this configuration, the air conditioning apparatus 10 of the present embodiment guides the adjusted air released from the air conditioning unit 12 to the second suction port 28a of the second air blowing unit 24 via the guide air passage 45. It is possible.

  As shown in FIG. 13, the blower unit 14 includes a stepping motor 35 as a drive source. The stepping motor 35 is a synchronous motor that operates in synchronization with pulse power. The use of the stepping motor 35 not only facilitates precise control in the lateral direction of the air flow, but also reduces the number of parts (that is, eliminates the need for a link mechanism that has been required in the past) and makes the rotating mechanism compact. There is an effect of making. A control unit (not shown) provided in the blower unit 14 allows the rotational angle of the stepping motor 35 to be set electrically. In other words, the control unit determines the angle of left and right swinging of the blower unit 14 by the user (use It is configured so that it can be changed according to the setting input by the operator. Specifically, as shown in FIG. 13, a fixing plate 37 is disposed behind the vent hole 27 of the bottom wall portion 24A. A stepping motor 35, a left / right swinging shaft 39, and origin detection means 41 are fixed to the fixed plate 37. The left / right swing shaft 39 is a left / right swing axis of rotation. The origin detection means 41 comprises an IR (infrared) sensor (for example, a phototransistor or the like). The origin detection means 41 may be composed of a magnet and a magnetic sensor. As shown in the figure, the blower unit 14 includes a left / right swing shaft 39 and swing guide portions 43a, 43b, 43c that are provided around the left / right swing shaft 39 and guide the left / right swing. Further, legs 47 a, 47 b, 47 c, 47 d for supporting the blower unit 14 are provided around the left and right swing shaft 39. According to such a configuration, since the left / right swing is guided along the swing guide portion, it is possible to prevent rattling during the left / right swing.

  As shown in FIGS. 1 and 2, a support plate 16 is interposed between the blower unit 14 and the air conditioning unit 12. As shown in FIG. 3, a fixed gear 49 is arranged on the support plate 16 coaxially with the vertical axis Lv serving as the rotation center of the blower unit 14, and in front of the vertical axis Lv, the air feed of the air conditioning unit 12 is performed. An opening 18 corresponding to the outlet 32 is formed, and an arcuate guide slit 21 is formed around the rotation axis so as to surround the rear of the fixed gear 49. As shown in FIG. 13, swing guide portions 43a, 43b, 43c are formed downward from the blower unit 14, and the tip of one swing guide portion 43a is formed in a hook shape and has an opening. It is caught in a groove formed in the curved edge 18a of the portion 18. In addition, a washer is provided at the tip of the other swinging guide portions 43b and 43c so as not to come out of the guide slit 21. In addition, the swing guide portions 43a, 43b, and 43c have a structure that turns only within a certain range corresponding to the maximum angle of the left and right swings, and thus also regulates the angle of the left and right swings.

  As shown in FIGS. 3 and 5, an arcuate guide rail 16 a is provided along the front of the opening 18. Moreover, as shown in FIG. 13, a roller (not shown) is attached to the tip of legs 47a, 47b, 47c, 47d provided downward from the blower unit 14, and the plurality of legs 47a, 47b. 47c and 47d, the rollers of some of the leg portions 47c and 47d come into contact with the guide rail 16a, and the rollers run on the guide rail 16a during the left and right swinging motion. A hole 49a is formed at the center of the fixed gear 49, and a left and right swing shaft 39 on the air blowing unit 14 side is attached to the hole 49a. Further, on the upper surface of the support plate 16, a projecting light shielding plate 57 that shields the origin detection means (IR sensor) 41 is formed. When light is shielded by the light shielding plate 57, the origin detection means (IR sensor) 41 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 14 faces the front.

  As described above, in the air conditioner 10 of this embodiment, the inlet side opening (reference numeral 18) of the induction air passage 45 is connected to the air outlet 32 of the air conditioning unit 12 (the first blower of the first blower 23). It is provided downstream of the outlet 50).

  As shown in FIGS. 6 and 7, in the air conditioner 10 of this embodiment, an airflow guide member 52 that guides air corresponding to the shape of the inflow side opening 18 is provided in the first air outlet 50. . The airflow guide member 52 forms a first air outlet 50 in cooperation with the casing 40 of the first air blowing unit 23. The 1st blower outlet 50 is open | released (directly) toward the inflow side opening part 18 of the induction | guidance | derivation wind path 45, and the 1st blower outlet 50 respond | corresponds to the shape of the inflow side opening part 18 in the example of a figure. And it is formed in a bow shape. The arcuate shape may be composed of two fan shapes that are partitioned into two at the center between both ends of the edge portion 56 that extends in a curved manner, or is provided between both ends of the edge portion 56. It may be composed of a plurality of rectangles having different shapes.

  A casing 40 of the illustrated first blowing section 23 has a pair of left and right side plates 50a and 50b facing each other and a side plate 50c connected to the left and right side plates 50a and 50b, and these three side plates 50a, 50b and 50c. Is formed in a U-shape. The airflow guide member 52 includes a pair of left and right side plates 52a and 52b fitted between a pair of side plates 50a and 50b of the casing, three side plates including one side plate 52c connected to the left and right side plates 52a and 52b, and three And a top plate 52d connected to the side plates 52a, 52b, 52c. Two rectangular locking recesses 51 that face each other are provided on the side plates 50a and 50b of the casing, and two elastically deformable lockings that face each other on the side plates 52a and 52b of the airflow guide member 52, respectively. A protrusion 53 is provided. The airflow guide member 52 is fitted into the casing 40 by the engagement of the locking projection 53 with the locking recess 51. The airflow guide member 52 has an arcuate (bow-shaped) side edge portion 56 corresponding to the inner edge of the arcuate guide rail 16 a of the support member 16.

  The airflow guide member 52 is formed so as to guide air with a guide surface having no step. As shown in FIG. 9, the airflow guide member 52 is provided with an arcuate (bow-shaped) edge 56 on the downstream side of the airflow, and has a linear edge 52e on the upstream side of the airflow. . Between the arc-shaped edge 56 and the straight edge 52e, a guide surface 68 that is smoothly curved is connected. Further, one side plate 52a of the airflow guide member 52 has an inclined surface portion 58 that has a lower end portion that abuts on a step 61 of the casing 40 and is curved in a concave shape that is continuously provided to a corner portion 58a of a protruding portion described later. (See FIG. 10). The airflow guide member 52 is configured to minimize the formation of a step at the mating portion with the casing, and can smoothly flow the airflow, thereby preventing the generation of noise due to the airflow hitting the step. .

  As shown in FIG. 10, the first blower 23 includes a multiblade centrifugal fan 38 and a casing 40 that rotatably supports the multiblade centrifugal fan 38, and the multiblade centrifugal fan 38 is rotated by a motor (not shown). By doing so, the multi-blade centrifugal fan 38 and the casing 40 are configured to generate an airflow jointly.

  In the airflow guide member 52, an inclined surface portion 58 is formed on at least a part of a guide surface located on the downstream side in the rotation direction of the multiblade centrifugal fan 38 so as to overlap a tangent L <b> 1 in contact with the outer peripheral edge of the multiblade centrifugal fan. As shown in FIG. 10, since the inclined surface portion 58 overlaps the tangent line L1, the air sent out along the tangential line L1 forward (indicated by the arrow 63) in the rotation direction by the multiblade centrifugal fan 38 is inclined surface portion 58. And flows almost parallel. This configuration reduces fluid energy loss or pressure loss. Moreover, from this, the flow of the air blown out from the first blower outlet 50 can be made smoother with less disturbance.

  As shown in FIGS. 9 and 10, the airflow guide member 52 has a protruding portion 70 at a position below the inclined surface portion 58, and is configured to receive an airflow from the multiblade centrifugal fan on the side surface of the protruding portion 70. ing. The protruding portion 70 is in contact with the distal end surface of the protruding portion 72 protruding from one side plate 50 a of the casing 40 at a position below the inclined surface portion 58. According to this, the side surface of the projecting portion 70 becomes the wind receiving surface portion 65 that receives the airflow sent from the multi-blade centrifugal fan 38, and the wind receiving surface portion 65 has no gap along the airflow feeding direction. This can prevent leakage of the dehumidified air through the gap and generation of pressure loss, noise, and the like when there is a gap along the airflow feeding direction. In other words, the seam 67 where the projecting portion 72 of the casing 40 and the projecting portion 70 are in contact with each other has almost no gap, or even if there is a gap, it is formed perpendicular to the air flow direction. Can be minimized.

  As shown in FIGS. 6 and 10, the first air outlet 50 is provided with a rectifying piece portion 62 provided on the side surface of the projecting portion 70 of the airflow guide member 52 so as to be opposed to each other. The rectifying piece 62 can be disposed at any position between the side plates 50a, 50b of the first outlet 50. In the illustrated example, the rectifying piece 62 is changed from one side plate 50a to the side plates 50a, 50b. It is provided at a position near the other side plate 50b, with a distance of about 2/3 of the distance between them. The rectifying piece portion 62 is disposed so as to substantially overlap the tangent line L2 (different from the tangent line L1) of the multiblade centrifugal fan 38. Preferably, the rectifying piece 62 is gently curved.

  At the first outlet 50, the airflow generated by the rotation of the multiblade centrifugal fan 38 tends to be blown toward the side surface (wind receiving surface portion 65) of the projecting portion 70 on the downstream side in the rotational direction. A pressure difference is generated between the space on the left side and the space on the right side in the drawing at the one outlet 50. The rectifying piece 62 guides the airflow flowing in the right space at the first outlet 50 in the direction parallel to the tangent L2 of the multiblade centrifugal fan 38 (the direction indicated by the arrow 69 in the figure), and the pressure difference Suppresses the occurrence of That is, the rectifying piece 62 prevents the occurrence of noise by preventing the wind fluttering phenomenon (turbulent airflow) caused by the pressure difference. Also, the energy loss or pressure loss of the fluid is reduced.

  In the air conditioning apparatus of the present embodiment, the air conditioning unit 12 includes an air adjusting unit 22 having a function of adjusting the humidity of air. That is, the dehumidifier (with a circulator) is illustrated as one form of an air conditioning apparatus.

  Here, the basic structure of the desiccant type dehumidifier will be described. For example, as shown in FIG. 4, a dehumidification rotor 36, a condenser (heat exchanger) 34, which will be described later, and a heater 42 are provided. It has the 1st ventilation part 23 comprised from the fan 38 and the casing 40. As shown in FIG. A temperature sensor 43 is attached to the heater 42. The temperature sensor 43 is made of bimetal, for example. As an action of the dehumidifier, the first air blowing unit 23 is operated, the indoor air is sucked through the air intake 30 of the housing 20, the dehumidifying rotor 36 is passed, and moisture in the air is adsorbed. Thereby, air is dehumidified in the housing 20. The water adsorbed by the dehumidifying rotor 36 is converted into water vapor by heating by the heater 42.

  As shown in FIG. 11, the water vapor generated by the heating of the heater 42 is introduced into a number of synthetic resin pipes 34 a constituting the condenser 34, cooled by the air existing in the housing 20, condensed, and condensed with water. Become. This water flows through the sub tank 46A disposed in the housing 20 and flows down to the main tank 46B which is disposed at the bottom of the housing 20 and communicates with the sub tank 46A, and is stored in the main tank.

  The air conditioning unit 22 includes a condenser 34 having a large number of synthetic resin pipes 34a arranged in parallel, and a comb-shaped member 72 having a large number of parallel teeth inserted between the large number of pipes of the condenser. Has been. The teeth 74 of the comb-shaped member 72 (see FIG. 12) are located between the pipes 34a of the condenser 34, and serve to correct deformation during the molding of the pipe 34a and prevent deformation over time during use. Thereby, the dehumidification performance of the condenser 34 is prevented from being lowered.

  Further, as shown in FIG. 12, each tooth 74 of the comb-shaped member 72 has a tapered tip end portion 74a. Thereby, the comb-shaped member 72 can be easily inserted between the multiple pipes 34 a of the condenser 34. In addition, this allows the teeth 74 of the comb-shaped member 72 to be inserted deeper, and the comb-shaped member 72 can be reliably held by the condenser 34.

  As shown in FIG. 11, the air conditioning unit 12 includes a temperature / humidity sensor 48 that detects temperature and humidity. The air conditioning unit 12 includes a control unit 71 (see FIG. 4) that controls heating of the dehumidifying rotor 36 by the heater 42 based on the humidity detected by the temperature / humidity sensor 48.

  Specifically, in the air conditioning unit 12, as shown in FIG. 14, the temperature / humidity is detected by the temperature / humidity sensor 48 (step S1), and then the indoor humidity detected by the temperature / humidity sensor 48 is detected. It is determined whether the (relative humidity) is less than a predetermined threshold (for example, 30%) (step S2). If the humidity (relative humidity) is less than the predetermined threshold, the heater 42 is switched off ( Step S3), the heating of the dehumidifying rotor 36 is controlled to stop. On the other hand, when the humidity (relative humidity) is equal to or higher than a predetermined threshold, the temperature / humidity detection by the temperature / humidity sensor 48 is repeated. The predetermined threshold value for switching the heater 42 to OFF is set to an arbitrary value in a humidity range of 20% to 40%, for example. After the heater 42 is switched off, when the relative humidity detected by the temperature / humidity sensor 48 exceeds another threshold value (for example, 35%) higher than the above threshold value, the heater 42 is switched on and the dehumidifying rotor 36 is switched on. The heating is controlled to resume (return). The threshold value for this return is set to an arbitrary value higher than the threshold value for switching the heater 42 OFF in the humidity range of 25% to 45%. Further, a plurality of stages of relative humidity threshold values are set in advance, and it is determined whether the humidity (relative humidity) detected by the temperature / humidity sensor 48 is less than the highest threshold value of the plurality of stages. 42, the output of the heater 42 is further reduced, and it is determined whether the output is less than the intermediate threshold value one step lower. In that case, the output of the heater 42 is further reduced, and the output of the heater 42 is reduced in a plurality of stages. And it is discriminate | determined whether it is less than the lowest threshold value of several stages, and you may control to switch the heater 42 to OFF in that case. Thus, it is also preferable to reduce the output of the heater 42 in a plurality of stages and finally switch the heater 42 to OFF. The air conditioning unit 12 prevents the dehumidification rotor 36 from being overheated by the control of the heater 42 described above, and heats the components made of synthetic resin that constitute peripheral devices (for example, the condenser 34) accompanying the overheating of the dehumidification rotor 36. The occurrence of melting, fire, etc. can be prevented.

  The air conditioning unit 12 controls the heating of the dehumidification rotor 36 by the heater 42 based on the temperature detected by the temperature / humidity sensor 48 in the control unit 71.

  Specifically, as shown in FIG. 15, the temperature / humidity is detected by the temperature / humidity sensor 48 (step S10), and then the temperature detected by the temperature / humidity sensor 48 is a predetermined threshold (eg, 38 ° C.). Is exceeded (step S11), and if the temperature exceeds a predetermined threshold, the heater 42 is switched off (step S12), and the heating of the dehumidifying rotor 36 is controlled to stop. On the other hand, if the temperature is equal to or lower than the predetermined threshold, the temperature / humidity detection by the temperature / humidity sensor 48 is repeated. The predetermined threshold for switching the heater 42 to OFF is set to an arbitrary value in a temperature range of 34 ° C. to 40 ° C., for example. After the heater 42 is switched off, when the temperature detected by the temperature / humidity sensor 48 falls below another threshold value (for example, 36 ° C.) lower than the threshold value, the heater 42 is switched on and the dehumidifying rotor 36 is switched on. The heating is controlled to resume (return). The threshold value for this return is set to an arbitrary value lower than the threshold value for switching the heater 42 to OFF in the temperature range of 32 ° C. to 38 ° C. Further, based on the temperature detected by the temperature / humidity sensor 48, the output of the heater 42 may be reduced to a plurality of stages and finally the heater 42 may be switched off.

  It is also preferable that the air conditioning unit 12 controls the heating of the dehumidification rotor 36 by the heater 42 based on the absolute humidity detected by the temperature / humidity sensor 48 in the control unit 71.

Specifically, as shown in FIG. 16, the temperature / humidity is detected by the temperature / humidity sensor 48 (step S20), and then the absolute humidity detected by the temperature / humidity sensor 48 is set to a predetermined first threshold (for example, 9.2 g / m ³ ) or less (step S21). If the absolute humidity is less than the first threshold, the output of the heater 42 is decreased, and then the second threshold and the third threshold. If... Is set, each threshold value is compared with the absolute humidity, and if it is less than the threshold value, the output of the heater 42 is sequentially decreased, and then a predetermined final threshold value (for example, 3. 0g / m ³ ) (step S22), and if the absolute humidity is less than the final threshold, the heater 42 is switched off (step S23) to stop heating the dehumidifying rotor 36. Control. After the heater 42 is turned off, a return threshold value is set for restarting (returning) heating of the dehumidifying rotor 36 by turning the heater 42 on.

  In addition to the control of the heater 42 by the temperature / humidity sensor 48 described above, the air conditioning unit 12 directly measures the temperature of the heater 42 by a temperature sensor (bimetal) 43 (see FIG. 4) attached to the outside of the heater 42. When the heating state is detected, the heater 42 is turned off. That is, the air conditioning unit 12 prevents the heating of the heater 42 by the temperature / humidity sensor 48 and the temperature sensor 43 attached to the heater 42, and takes double safety measures.

  The air conditioning unit 12 includes a weight sensor that detects the amount of water that flows from the condenser 34 to the sub tank 46A and the main tank 46B, and the dehumidification rotor 36 by the heater 42 based on the amount of water detected by the weight sensor. The heating may be controlled. That is, when the amount of water flowing from the condenser 34 to the sub tank 46A / main tank 46B is less than a predetermined small amount, the heater 42 is turned off or the output of the heater 42 is reduced.
