Various modifications can be made to this embodiment based on the description of the claims.

Referring to FIGS. 1 and 2, the air conditioner according to the present embodiment is indicated generally by reference numeral 10. As shown in FIG. The air conditioning apparatus 10 of this embodiment includes an air conditioning unit 12 for adjusting indoor air, and a blower unit 14 for sending out the air (conditioned air) adjusted by the air conditioning unit 12 indoors.

As shown in FIG. 4, the air conditioning unit 12 includes an air adjustment unit 22 that adjusts at least one of the temperature, humidity, and cleanliness of the air, and a first suction port 44 that receives the adjusted air adjusted by the air adjustment unit. and a first air blower 23 for sucking air from and discharging air from the first outlet 50 . The air conditioning unit 12 contains an air adjusting section 22 and a first air blowing section 23 inside a box-shaped housing 20 .

As shown in FIGS. 1 and 2, the blower unit 14 includes a second blower section 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 section. ing.

The second air blower 24 includes a housing 28 and a blower fan 29 (see FIG. 2) housed in the housing 28 and 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 with a side wall portion. That is, the side wall of the housing 28 forms a wind tunnel, which has the advantage of improving the straightness of the air flow generated by the blower fan 29 . The second air blower 24 has a second suction port 28a for sucking the conditioned air discharged from the air conditioning unit 12 into the housing 28, and a second suction port 28a for sucking the conditioned air sucked into the housing 28 into the room outside the housing 28. and a second outlet 28b for blowing out. A spiral panel 31 is provided at the second outlet 28b. The spiral panel 31 turns the airflow generated by the blower fan 29 into a spiral airflow, and the spiral airflow advances straight while spirally eddying, allowing the conditioned air discharged from the air conditioning unit 12 to reach a farther distance. There is an advantage that The second air blower 24 is further held (pivoted) by the holding frame 26 so as to be rotatable about the horizontal axis Lh (see FIG. 1). That is, the second air blower 24 is configured to be vertically swingable.

The blower unit 14 is rotatably supported with respect to the air conditioning unit 12 about a vertical axis Lv (see FIGS. 1 and 2). That is, the blower unit 14 is configured to be swingable in the horizontal direction.

The air conditioning unit 12 and the blower unit 14 are in a swinging reference posture (the state shown in FIGS. 1 and 2 in which the blower unit 14 faces the front and the second outlet 28b faces straight up). When the air conditioning unit 12 is in a certain resting posture, the air conditioning unit 12 is formed so as to form an integral box shape having continuity, as if the blower unit 14 is placed on the air conditioning unit 12 . In the reference posture, the gap between the air conditioning unit 12 and the blower unit 14 is narrow, and the gap between the air conditioning unit 12 and the blower unit 14 is flat without a step, so that dust and dirt are less likely to enter the air conditioning unit 12. .

The air conditioning unit 12 has an air intake port 30 on the rear surface 20b of the housing 20, and an air delivery port 32 (see FIG. 10) for delivering air adjusted by the air conditioning unit 12 inside the housing 20 to the outside of the housing 20. ) is provided in an opening on the upper surface (top surface) 20c.

As shown in FIGS. 1 and 13, the blower unit 14 has a bottom wall portion of a holding frame 26 formed with a vent hole 27 communicating in the vertical direction. The vent 27 is a large number of windows (gaps) formed over substantially the entire surface of the bottom wall. The air outlets 27 of the air conditioning unit 12 are arranged in such a way that the many air outlets 27 on the bottom wall correspond to the air outlets 32 of the air conditioning unit 12 no matter which direction the blower unit 14 swings in the horizontal direction. It is formed in a wider range than the delivery port 32 . A holding frame 26 of the blower unit 14 has side wall portions 26a and 26b on both left and right sides, and a rear wall portion 26c on the rear side. Therefore, the holding frame 26 has a U-shape in plan view with the left and right side wall portions 26a and 26b and the rear wall portion 26c. be. In addition, since not only the adjusted air is taken in through the vent hole 27 formed in the bottom wall portion but also the outside air is taken in through the vent hole 33 formed in the rear wall portion 26c, the amount of air supplied to the second blower portion 24 is reduced. It is possible to secure enough. A suction port is formed over substantially the entire surface of the substantially arcuate bottom surface of the second air blower 24 . Even if the second air blower 24 swings in any direction in the vertical direction, a constant distance is maintained between the substantially arcuate bottom surface and the vent hole 27 in the bottom wall portion.

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

The guide air passage 45 is provided on the downstream side of the air delivery port 32 of the air conditioning unit 12, and has an opening 18 of the support plate 16, which will be described later, as an inflow side (entrance). 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. A holding frame 26 of the blower unit 14 is provided so as to cover the air delivery port 32 of the air conditioning unit 12 , and the lower part of the holding frame 26 is arranged close to the upper part of the air conditioning unit 12 . With this configuration, the air conditioner 10 of the present embodiment guides the conditioned air discharged from the air conditioning unit 12 to the second suction port 28a of the second air blower 24 via the guide air passage 45. It is possible.

As shown in FIG. 13, the blower unit 14 has 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 accurate control of the left and right air blowing direction, but also has the effect of reducing the number of parts (that is, eliminating the need for a link mechanism that was conventionally required) and compacting the rotation mechanism. It has the effect of transformation. A 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 allows the user (using It is configured so that it can be changed according to the setting input by the operator's operation. Specifically, as shown in FIG. 13, a fixing plate 37 is arranged behind the vent 27 of the bottom wall portion 24A. A stepping motor 35 , a laterally swinging shaft 39 , and an origin detecting means 41 are fixed to the fixed plate 37 . The left-right swing shaft 39 is a left-right swing rotation shaft. The origin detection means 41 consists of an IR (infrared) sensor (for example, a phototransistor, etc.). Note that the origin detection 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-right swing shaft 39 and swing guide portions 43a, 43b, and 43c provided around the left-right swing shaft 39 to guide the left-right swing. Further, leg portions 47a, 47b, 47c, and 47d for supporting the blower unit 14 are provided around the shaft 39 for lateral swing. According to such a configuration, since the lateral swing is guided along the swing guide portion, it is possible to prevent looseness during the lateral 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, which is the center of rotation of the blower unit 14. An opening 18 corresponding to the outlet 32 is formed, and an arc-shaped 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, and 43c are formed downward from the blower unit 14, and the tip of one swing guide portion 43a is formed into a hook-like shape and is open. It is adapted to be caught in a groove formed in the curved edge 18a of the portion 18. As shown in FIG. Also, washers are provided at the tips of the other swing guide portions 43b and 43c so that they do not slip out of the guide slit 21. As shown in FIG. In addition, since the swing guide portions 43a, 43b, and 43c are structured to rotate only within a certain range corresponding to the maximum angle of left/right swing, they also regulate the angle of left/right swing.

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

As described above, in the air conditioner 10 of this embodiment, the inflow side opening (reference numeral 18) of the induction air passage 45 is connected to the air delivery port 32 (the first blower of the first blower section 23) of the air conditioning unit 12. 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 at the first outlet 50. . The airflow guide member 52 forms the first outlet 50 together with the casing 40 of the first blower section 23 . The first air outlet 50 opens toward (orients to) the inflow side opening 18 of the guide 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 an arcuate shape. In addition, the arcuate shape may be composed of two sectors that are divided into two at the center between both ends of the edge portion 56 that curves and extends, or that is provided side by side between both ends of the edge portion 56 . It may consist of a plurality of rectangles with different shapes.

The casing 40 of the illustrated first air blower 23 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. is formed to form a U shape. The airflow guide member 52 includes 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, and 52c. Side plates 50a and 50b of the casing are provided with two rectangular engaging recesses 51 facing each other, and both side plates 52a and 52b of the airflow guide member 52 are provided with two elastically deformable engaging recesses facing each other. A protrusion 53 is provided. The airflow guide member 52 is fitted to the casing 40 by the engagement of the locking projections 53 with the locking recesses 51 . The airflow guide member 52 has an arcuate (arcuate) 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 stepless guide surface. As shown in FIG. 9, the airflow guide member 52 has an arcuate (arcuate) edge 56 on the downstream side of the airflow and a linear edge 52e on the upstream side of the airflow. . A smoothly curved guide surface 68 connects the arcuate edge portion 56 and the linear edge portion 52e. One side plate 52a of the airflow guide member 52 has a concavely curved inclined surface portion 58 that abuts on the stepped portion 61 of the casing 40 at its lower end portion and is connected to a corner portion 58a of a projecting 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, allowing the airflow to flow smoothly and preventing the generation of noise due to the airflow hitting the step. .

As shown in FIG. 10, the first air blower 23 includes a multi-blade centrifugal fan 38 and a casing 40 that rotatably supports the multi-blade centrifugal fan 38. 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 cooperate with each other to generate an airflow.

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 and overlapping a tangent line L1 that contacts the outer peripheral edge of the multi-blade centrifugal fan. As shown in FIG. 10, since the inclined surface portion 58 overlaps with the tangent line L1, the air sent out along the tangent line L1 forward (indicated by an arrow 63) in the direction of rotation of the multi-blade centrifugal fan 38 is directed to the inclined surface portion 58. flows almost parallel to the This configuration reduces energy or pressure losses in the fluid. Moreover, from this, the flow of the air blown out from the first blower outlet 50 can be made smoother with less turbulence.

As shown in FIGS. 9 and 10, the airflow guide member 52 has a projecting portion 70 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 projecting portion 70. ing. The projecting portion 70 is in contact with the tip surface of a projecting portion 72 projecting 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 serves as the wind receiving surface portion 65 that receives the airflow sent out from the multi-blade centrifugal fan 38, and the wind receiving surface portion 65 can be made free of gaps along the direction of the airflow. As a result, it is possible to prevent the dehumidified air from leaking through the gap in the case where the gap exists along the direction of air flow, and the accompanying pressure loss, noise, and the like. In other words, the seam 67 between the protruding portion 72 of the casing 40 and the protruding portion 70 is formed in a state in which there is almost no gap, or even if there is a gap, the joint 67 is formed perpendicular to the airflow feeding direction, resulting in pressure loss. can be minimized.

As shown in FIGS. 6 and 10, the first blowout port 50 is provided with rectifying pieces 62 provided on the side surface of the protruding portion 70 of the airflow guide member 52 so as to face each other with a space therebetween. The rectifier portion 62 can be arranged at any position between the side plates 50a and 50b of the first outlet 50. In the illustrated example, the rectifier portion 62 extends from one side plate 50a to the side plates 50a and 50b. is provided at a position closer to the other side plate 50b, separated by about 2/3 of the distance between the two. The rectifying piece portion 62 is arranged so as to substantially overlap a tangent line L2 (different from the tangent line L1) of the multi-blade centrifugal fan 38 . Preferably, the rectifying piece portion 62 is gently curved.

At the first air 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 projecting portion 70 on the downstream side in the rotational direction. A pressure difference is generated between the space on the left side of the drawing and the space on the right side of the air outlet 50 . The rectifying piece 62 guides the airflow flowing in the space on the right side of the first air outlet 50 in a direction parallel to the tangential line L2 of the multi-blade centrifugal fan 38 (the direction indicated by the arrow 69 in the figure), thereby reducing the pressure difference. suppress the occurrence of That is, the rectifying piece portion 62 prevents the flapping phenomenon (turbulence) of the wind caused by the pressure difference, thereby preventing the generation of noise. Also, the energy loss or pressure loss of the fluid is reduced.

In the air conditioner of this embodiment, the air conditioning unit 12 has an air adjustment section 22 having a function of adjusting the humidity of the air. That is, a dehumidifier (with a circulator) is exemplified as one form of the air conditioner.

Here, the basic structure of a desiccant type dehumidifier will be described. For example, as shown in FIG. It has a first air blower 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 bimetal, for example. The operation of the dehumidifier is to operate the first air blower 23 to suck the air in the room through the air intake 30 of the housing 20, pass it through the dehumidification rotor 36, and adsorb moisture in the air. This dehumidifies the air inside the housing 20 . The moisture adsorbed by the dehumidification rotor 36 is heated by the heater 42 to be vaporized.

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

The air adjustment 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 mutually parallel teeth inserted between the large number of pipes of the condenser. It is 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 deformation of the pipes 34a during molding and prevent deformation over time during use. This prevents the dehumidification performance of the condenser 34 from deteriorating.

Also, as shown in FIG. 12, each tooth 74 of the comb member 72 has a tapered tip 74a. This makes it easy to insert the comb-shaped member 72 between the many pipes 34a of the condenser 34 . In addition, this allows the teeth 74 of the comb-shaped member 72 to be inserted more deeply, so that 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 section 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 and humidity are detected by the temperature and humidity sensor 48 (step S1). (relative humidity) determines whether it is less than a predetermined threshold (for example, 30%) (step S2), and if the humidity (relative humidity) is less than the predetermined threshold, the heater 42 is turned off ( Step S3), control is performed to stop the heating of the dehumidification rotor 36; On the other hand, when the humidity (relative humidity) is equal to or higher than the predetermined threshold, the temperature/humidity sensor 48 repeats detection of temperature and humidity. The predetermined threshold for turning off the heater 42 is set to any value in the humidity range of, for example, 20% to 40%. 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 to dehumidify the rotor 36. control to resume (return) the heating of The threshold for this return is set to any value above the threshold for turning off the heater 42 in the humidity range of 25% to 45%. In addition, a plurality of stages of relative humidity thresholds 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 among the plurality of stages. 42 is reduced, and it is further determined whether or not it is less than an intermediate threshold lower by one step, in which case the output of the heater 42 is further reduced, and the reduction of the output of the heater 42 is performed in a plurality of stages. Then, it is determined whether or not it is less than the lowest threshold value among the plurality of stages, and in that case, the heater 42 may be controlled to be turned off. In this way, it is also preferable to reduce the output of the heater 42 in multiple stages and finally turn off the heater 42 . The air conditioning unit 12 prevents overheating of the dehumidifying rotor 36 by controlling the heater 42 described above, and also reduces the heat of the synthetic resin parts that make up the peripheral equipment (for example, the condenser 34) caused by the overheating of the dehumidifying rotor 36. The occurrence of melting, fire, etc. can be prevented.

Also, 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 controller 71 .

Specifically, as shown in FIG. 15, the temperature and humidity are detected by the temperature/humidity sensor 48 (step S10). is exceeded (step S11), and if the temperature exceeds a predetermined threshold value, the heater 42 is turned 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 sensor 48 repeats detection of temperature and humidity. The predetermined threshold for turning off the heater 42 is set to an arbitrary value within the temperature range of 34°C to 40°C, for example. After the heater 42 is turned off, when the temperature detected by the temperature/humidity sensor 48 falls below another threshold (for example, 36° C.) lower than the above threshold, the heater 42 is turned on to dehumidify the rotor 36 . control to resume (return) the heating of The threshold for this return is set to any value below the threshold for turning off the heater 42 in the temperature range of 32°C to 38°C. Alternatively, based on the temperature detected by the temperature/humidity sensor 48, the output of the heater 42 may be reduced in a plurality of steps, and finally the heater 42 may be turned off.

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

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

In addition to controlling the heater 42 by the temperature and 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, is detected, the heater 42 is turned off. That is, the air conditioning unit 12 prevents the heater 42 from overheating by using the temperature/humidity sensor 48 and the temperature sensor 43 attached to the heater 42, thereby taking double safety measures.

The air conditioning unit 12 includes a weight sensor for detecting the amount of water flowing down from the condenser 34 to the sub-tank 46A and the main tank 46B. heating may be controlled. That is, when the amount of water flowing down from the condenser 34 to the sub-tank 46A/main tank 46B is less than a predetermined amount, the heater 42 is turned off or the output of the heater 42 is reduced.
