Further, the embodiments shown below exemplify devices and methods for embodying the technical idea, and do not specify the materials, shapes, structures, arrangements, etc. of the component parts to the following. .. Various modifications can be made to this embodiment based on the description of the scope of claims.

With reference to FIGS. 1 and 2, the air conditioner according to the present embodiment is indicated by reference numeral 10 as a whole. The air conditioning device 10 of the present embodiment includes an air conditioning unit 12 for adjusting the air in the room and a blowing unit 14 for sending out the air (adjusted air) adjusted by the air conditioning unit 12 into the room.

As shown in FIG. 4, the air conditioning unit 12 has an air adjusting unit 22 that adjusts at least one of the temperature, humidity, and cleanliness of the air, and a first suction port 44 that adjusts the adjusted air adjusted by the air adjusting unit. It has a first air blowing unit 23 for sucking in from the air and releasing it from the first air outlet 50. In the air conditioning unit 12, the air adjusting unit 22 and the first air blowing unit 23 are housed inside the box-shaped housing 20.

As shown in FIGS. 1 and 2, the blower unit 14 includes a second blower portion 24 that sucks and blows out the adjusted air adjusted by the air conditioning unit, and a holding frame 26 that holds the second blower portion. ing.

The second blower portion 24 includes a housing 28 and a drive-rotated blower fan 29 (see FIG. 2) housed inside the housing 28. 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 radial outer side of the blower fan 29 at the side wall portion. That is, there is an advantage that the wind tunnel portion is formed by the side wall portion of the housing 28 to improve the straightness of the air flow generated by the blower fan 29. The second blower unit 24 has a second suction port 28a that sucks the adjusting air discharged from the air conditioning unit 12 into the housing 28, and the adjusting air sucked into the housing 28 into a room outside the housing 28. It has a second outlet 28b for blowing out. A swirl panel 31 is provided at the second outlet 28b. The spiral panel 31 uses the air flow generated by the blower fan 29 as a spiral air flow, and the spiral air flow travels straight while spirally swirling, so that the adjusting air discharged from the air conditioning unit 12 reaches a farther distance. There is an advantage that can be done. The second blower portion 24 is further rotatably held (coordinated) around the horizontal axis Lh (see FIG. 1) by the holding frame 26. That is, the second blower portion 24 is configured to swing in the vertical direction.

It is formed so as to form an integral box shape having continuity as if the blower unit 14 was placed on the air conditioning unit 12 when the air conditioning unit 12 was placed in the stationary posture. In the reference posture, the gap between the air conditioning unit 12 and the blower unit 14 is narrow, and there is no step between the air conditioner unit 12 and the blower unit 14 so that the air conditioning unit 12 is flat and 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 outlet 32 for sending air adjusted by the internal air conditioning unit 12 to the outside of the housing 20 (see FIG. 10). ) Is provided in an opening shape on the upper surface (top surface) 20c.

As shown in FIGS. 1 and 13, the ventilation unit 14 is formed with a vent 27 that communicates in the vertical direction on the bottom wall portion of the holding frame 26. The vent 27 is a large number of windows (gap) formed over almost the entire surface of the bottom wall. No matter which direction the blower unit 14 swings in the left-right direction, the vents 27 correspond to the air outlets 32 of the air conditioning unit 12 so that the large number of vents 27 on the bottom wall correspond to the air outlets 32 of the air conditioning unit 12. It is formed in a wider range than the outlet 32. The holding frame 26 of the blower unit 14 is provided with side wall portions 26a and 26b on both left and right sides, and is provided with a rear wall portion 26c on the rear side. Therefore, the holding frame 26 has a U-shape in a plan view at the left and right side wall portions 26a and 26b and the rear wall portion 26c, and the entire amount of the adjusting air can be blown without escaping, so that sufficient dehumidification performance can be ensured. is there. Further, not only the adjusting 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 increased. It is possible to secure a sufficient amount. Further, a suction port is formed on the substantially arcuate bottom surface of the second blower portion 24 over almost the entire surface. Regardless of which direction the second blower portion 24 swings in the vertical direction, the substantially arcuate bottom surface and the vent 27 of the bottom wall portion maintain a constant distance.

As shown in FIGS. 1 and 10, the air conditioning device 10 of the present embodiment is provided with an induction air passage 45 that guides the regulated air discharged from the air conditioning unit 12 to the second suction port 28a of the second blowing unit 24. ing.

It is formed by a vent 27 formed in the above, and a space surrounded by the left and right side wall portions 26a and 26b of the holding frame 26 and the rear wall portion 26c. The holding frame 26 of the blower unit 14 is provided so as to cover the air outlet 32 of the air conditioning unit 12, and the lower portion of the holding frame 26 is arranged so as to be close to the upper portion of the air conditioning unit 12. With this configuration, the air conditioning device 10 of the present embodiment guides the regulated air discharged from the air conditioning unit 12 to the second suction port 28a of the second blowing unit 24 via the induction 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. If the stepping motor 35 is used, not only the precise control of the ventilation in the left-right direction becomes easy, but also the effect of reducing the number of parts (that is, the link mechanism that has been required in the past becomes unnecessary) and the compact rotation mechanism are achieved. It has the effect of conversion. The control unit (not shown) provided in the blower unit 14 can electrically set the rotation angle of the stepping motor 35, in other words, the control unit sets the angle of the left and right swing of the blower unit 14 by the user (used). It is configured so that it can be changed according to the setting input by the operation of the person). Specifically, as shown in FIG. 13, the fixing plate 37 is arranged behind the vent 27 of the bottom wall portion 24A. A stepping motor 35, a left-right swing shaft 39, and an origin detecting means 41 are fixed to the fixing plate 37. The left-right swing axis 39 is a left-right swing rotation axis. The origin detecting means 41 includes an IR (infrared) sensor (for example, a phototransistor). The origin detecting means 41 may be composed of a magnet, a magnetic sensor, or the like. As shown in the figure, the blower unit 14 includes a left and right swing shaft 39 and swing guide portions 43a, 43b, and 43c provided around the left and right swing shaft 39 to guide the left and right swing. Further, legs 47a, 47b, 47c, 47d for supporting the blower unit 14 are provided around the shaft 39 for swinging left and right. According to such a configuration, since the left and right swings are guided along the swing guide portion, it is possible to prevent rattling during the left and right swings.

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 which is the rotation center of the blower unit 14, and the air supply of the air conditioning unit 12 is in front of the vertical axis Lv. An opening 18 corresponding to the outlet 32 is formed, and an arc-shaped guide slit 21 is formed around the center of rotation 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 thereof is formed in a hook shape and opens. It is designed to be hooked on the groove formed in the curved edge 18a of the portion 18. Further, a washer is provided at the tip of the other swing guide portions 43b and 43c so as not to come out of the guide slit 21. Further, since the swing guide portions 43a, 43b, and 43c have a structure in which they turn only in a certain range according to the maximum angle of the left and right swings, the angle of the left and right swings is also regulated.

As shown in FIGS. 3 and 5, an arcuate guide rail 16a is provided along the front of the opening 18. Further, as shown in FIG. 13, rollers (not shown) are attached to the tips of the legs 47a, 47b, 47c, 47d provided downward from the blower unit 14, and the plurality of legs 47a, 47b are attached. , 47c, 47d, some of the legs 47c, 47d are in contact with the guide rail 16a, and the rollers run on the guide rail 16a during the left and right swinging operation. Further, a hole 49a is formed in the central portion of the fixed gear 49, and a shaft 39 for swinging left and right on the blower unit 14 side is attached to the hole 49a. Further, on the upper surface of the support plate 16, a convex light-shielding plate 57 that shields the origin detecting means (IR sensor) 41 from light is formed. When the light is shielded by the light-shielding plate 57, the origin detecting means (IR sensor) 41 detects the origin of the left-right swing. In the present invention, the origin of the left-right swing indicates the reference posture in which the blower unit 14 faces the front.

As described above, in the air conditioner 10 of the present embodiment, the inflow side opening (reference numeral 18) of the induction air passage 45 is the air outlet 32 of the air conditioning unit 12 (the first blow of the first air conditioner 23). It is provided on the downstream side of the exit 50).

As shown in FIGS. 6 and 7, in the air conditioner 10 of this embodiment, an airflow guide member 52 for guiding air corresponding to the shape of the inflow side opening 18 is provided at the first outlet 50. .. The airflow guide member 52 forms the first air outlet 50 in cooperation with the casing 40 of the first air blower 23. The first air outlet 50 is open (directed) toward the inflow side opening 18 of the induction air passage 45, and in the illustrated example, the first air outlet 50 corresponds to the shape of the inflow side opening 18. It is formed in a bow shape. The bow shape may be composed of two fan shapes divided into two at the center between both ends of the curved and extending edge portion 56, or may be provided between both ends of the edge portion 56. It may consist of a plurality of rectangles having different shapes.

The casing 40 of the first blower portion 23 in the figure has a pair of left and right side plates 50a and 50b facing each other, and one 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 to form a U-shape. The airflow guide member 52 includes three side plates consisting of a pair of left and right side plates 52a and 52b fitted between the pair of side plates 50a and 50b of the casing, and one side plate 52c connected to the left and right side plates 52a and 52b. It has a top plate 52d connected to the side plates 52a, 52b, 52c. The side plates 50a and 50b of the casing are provided with two rectangular locking recesses 51 facing each other, and the side plates 52a and 52b of the airflow guide member 52 are provided with two elastically deformable locking recesses facing each other. A protrusion 53 is provided. The airflow guide member 52 is fitted to the casing 40 by engaging the locking projection 53 with the locking recess 51. The airflow guide member 52 has an arc-shaped (bow-shaped) edge portion 56 corresponding to the inner edge of the arc-shaped guide rail 16a of the support member 16.

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

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

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

As shown in FIGS. 9 and 10, the airflow guide member 52 has a protrusion 70 at a position below the inclined surface portion 58, and is configured to receive the airflow from the multi-blade centrifugal fan on the side surface of the protrusion 70. ing. The protruding portion 70 is in contact with the tip surface of the protruding portion 72 protruding from one side plate 50a 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 air receiving surface portion 65 can be prevented from having a gap along the airflow feeding direction. As a result, it is possible to prevent the dehumidified air from leaking through the gap when there is a gap along the airflow feed direction, and the pressure loss and noise generated due to the leakage. In other words, the joint 67 where the protruding portion 72 of the casing 40 and the protruding portion 70 are in contact with each other has almost no gap, or even if there is a gap, it is formed orthogonally to the airflow feeding direction, resulting in pressure loss. Can be minimized.

As shown in FIGS. 6 and 10, the first air outlet 50 includes a rectifying piece portion 62 provided on the side surface of the protruding portion 70 of the airflow guide member 52 so as to face each other at intervals. The rectifying piece portion 62 can be arranged at an arbitrary position between the side plates 50a and 50b of the first outlet 50, and in the illustrated example, the rectifying piece portion 62 is arranged from one side plate 50a to the side plates 50a and 50b. It is provided at a position closer to the other side plate 50b, separated by about two-thirds of the distance between the two. The rectifying piece portion 62 is arranged so as to substantially overlap the tangent line L2 (different from the tangent line L1) of the multi-blade centrifugal fan 38. Preferably, the straightening piece portion 62 is gently curved.

At the first outlet 50, the airflow generated by the rotation of the multi-blade centrifugal fan 38 tends to be blown toward the side surface (wind receiving surface portion 65) of the protruding portion 70 on the downstream side in the rotation direction. There is a pressure difference between the space on the left side and the space on the right side in the figure at the 1 outlet 50. The rectifying piece portion 62 guides the airflow flowing through the space on the right side of the first outlet 50 in a direction parallel to the tangent line L2 of the multi-blade centrifugal fan 38 (the direction indicated by the arrow 69 in the figure), and the pressure difference. Suppress the occurrence of. That is, the rectifying piece portion 62 prevents the fluttering phenomenon (turbulence) of the wind generated due to the pressure difference, and prevents the generation of noise. Also, the energy loss or pressure loss of the fluid is reduced.

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

Here, the basic structure of the desiccant type dehumidifier will be described. For example, as shown in FIG. 4, a dehumidifying rotor 36, a condenser (heat exchanger) 34 described later, and a heater 42 are provided, and a multi-blade centrifuge is provided. It has a first blower portion 23 composed of a fan 38 and a casing 40. A temperature sensor 43 is attached to the heater 42. The temperature sensor 43 is made of, for example, a bimetal. As an action of the dehumidifier, the first blower 23 is operated to suck the air in the room through the air intake 30 of the housing 20, pass through the dehumidifying rotor 36, and adsorb the moisture in the air. As a result, the air is dehumidified in the housing 20. Moisture adsorbed by the dehumidifying rotor 36 is converted into steam by heating with the heater 42.

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

The air adjusting unit 22 includes a condenser 34 having a large number of synthetic resin pipes 34a arranged in parallel, and is provided with a comb-shaped member 72 having a large number of parallel teeth inserted between the large number of pipes of the condenser. Has been done. The teeth 74 (see FIG. 12) of the comb-shaped member 72 are located between the pipes 34a of the condenser 34, and serve to correct the deformation of the pipes 34a during molding and to prevent the deformation over time during use. This prevents deterioration of the dehumidifying performance of the condenser 34.

Further, as shown in FIG. 12, each tooth 74 of the comb-shaped member 72 has a tapered tip portion 74a. This makes it possible to easily insert the comb-shaped member 72 between a large number of pipes 34a of the condenser 34. Further, as a result, the teeth 74 of the comb-shaped member 72 can 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. It is determined whether (relative humidity) is less than a predetermined threshold value (for example, 30%) (step S2), and if the humidity (relative humidity) is less than a predetermined threshold value, the heater 42 is switched to OFF (step S2). Step S3), the dehumidifying rotor 36 is controlled to stop heating. On the other hand, when the humidity (relative humidity) is equal to or higher than a predetermined threshold value, the temperature / humidity detection by the temperature / humidity sensor 48 is repeated. A predetermined threshold value for switching the heater 42 to OFF is set to, for example, an arbitrary value in the humidity range of 20% to 40%. After switching the heater 42 to 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 to ON to dehumidify the rotor 36. Control to restart (return) the heating of. The threshold value for this return is set to an arbitrary value higher than the threshold value for switching the heater 42 to OFF in the humidity range of 25% to 45%. Further, a threshold value of the relative humidity of a plurality of stages is 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 among the plurality of stages. In that case, the heater The output of 42 is reduced, and it is determined whether or not the threshold value is lower than the intermediate threshold value, which is 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. Then, it may be determined whether or not the threshold value is less than the lowest threshold value among the plurality of stages, and in that case, the heater 42 may be controlled to be switched to OFF. In this way, 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 dehumidifying rotor 36 from overheating by controlling the heater 42 described above, and also heats the synthetic resin parts constituting the peripheral device (for example, the condenser 34) due to the overheating of the dehumidifying rotor 36. It is possible to prevent the occurrence of melting, fire, etc.

Further, the air conditioning unit 12 controls the heating of the dehumidifying 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 value (for example, 38 ° C.). (Step S11), and if the temperature exceeds a predetermined threshold value, the heater 42 is switched to OFF (step S12) to control the dehumidifying rotor 36 to stop heating. On the other hand, if the temperature is equal to or less than a predetermined threshold value, 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, for example, an arbitrary value in the temperature range of 34 ° C. to 40 ° C. After switching the heater 42 to OFF, when the temperature detected by the temperature / humidity sensor 48 drops below another threshold (for example, 36 ° C.) lower than the above threshold, the heater 42 is switched to ON to dehumidify the rotor 36. Control to restart (return) the heating of. 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, the output of the heater 42 may be reduced in a plurality of stages based on the temperature detected by the temperature / humidity sensor 48, and finally the heater 42 may be switched off.

It is also preferable that the air conditioning unit 12 controls the heating of the dehumidifying rotor 36 by the heater 42 based on the absolute humidity detected by the temperature / humidity sensor 48 by 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 value (for example,). It is determined whether it is less than 9.2 g / m ³ ) (step S21), and if the absolute humidity is less than the first threshold value, the output of the heater 42 is reduced, and then the second threshold value and the third threshold value are reduced. 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 reduced, and then a predetermined final threshold value (for example, 3. It is determined whether it is less than 0 g / m ³ ) (step S22), and if the absolute humidity is less than the final threshold value, the heater 42 is switched off (step S23) to stop the heating of the dehumidifying rotor 36. Control. After switching the heater 42 to OFF, a recovery threshold value for switching the heater 42 to ON and restarting (returning) the heating of the dehumidifying rotor 36 is set.

In addition to controlling 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, and the heater 42. When the heating state of is detected, the heater 42 is switched to OFF. That is, the air conditioning unit 12 prevents the heater 42 from being heated 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 flowing down from the condenser 34 to the sub tank 46A and the main tank 46B, and the dehumidifying rotor 36 by the heater 42 based on the amount of water detected by the weight sensor.
