Abstract
This invention inhibits the turbulence of airflow of conditioned air that is blown out from a blowout part and improves the energy efficiency of air conditioning when branching the conditioned air by a mounting structure part of a motor for driving a flap. An air conditioner having: a casing including a suction opening for sucking in indoor air and a blowout part for blowing out conditioned air; and a blower and a heat exchanger housed inside the casing has a flap 303 which is mounted on the blowout part and which adjusts the blowing direction of the conditioned air, and a motor 50 which serves as a drive source for oscillating the flap 303 and is provided at a position which avoids lengthwise ends of the blowout part.

Description
- The present invention relates to an air conditioner that is installed in a ceiling in a room, and to a casing and a decorative panel of such an air conditioner, and in particular relates to the conditioned air blowout structure thereof.
- As a method of improving the indoor temperature irregularity by expanding the airflow distribution of the conditioned air that is blown out by an air conditioner, for example, there is the method of increasing the number of blowout parts for blowing out air conditioner as with the ceiling-embedded air conditioner disclosed in
Patent Document 1. With the air conditioner disclosed inPatent Document 1, in addition to the four main blowout parts, since four auxiliary blowout parts are provided between the adjacent main blowout parts, the conditioned air is blown out in eight directions. - Moreover, in addition to increasing the number of blowout parts, it is also possible to improve the indoor temperature irregularity by expanding the airflow distribution of conditioned air as a result of devising the structure of the blowout parts. For example, there is a method of providing a motor to serve as a drive source for oscillating a flap which adjusts the blowing direction of the conditioned air by avoiding the lengthwise ends of the blowout part, rather than at the ends of the blowout part. In the foregoing case, the conditioned air that is blown out of that blowout part will hit the mounting structure part of the motor and be branched by such mounting structure part. Thus, the airflow distribution of the conditioned air will expand, and it is thereby possible to improve the indoor temperature irregularity.
- Nevertheless, in the case of branching the conditioned air by the mounting structure part of the motor for driving the flap, there is a problem in that the airflow of the conditioned air that is blown out from the blowout part becomes turbulent, and the energy efficiency of air conditioning will deteriorate.

Thesuction opening 101 is positioned at the center of the bottom part of thecasing 10, and formed as a result of asuction opening 201 provided to thecasing body 200 and asuction opening 301 provided to thedecorative panel 300 being combined. The fourblowout parts 102 are positioned around thesuction opening 101 in a manner of surrounding thesuction opening 101, extend in a direction along the outer edge part of thebottom part 200 a, the ends thereof are bent in a direction of approaching each other, and the fourblowout parts 102 is formed in a substantial octagon shape as a whole. Theblowout part 102 is formed by ablowout part 202 provided to thecasing body 200 and ablowout part 302 provided to thedecorative panel 300 being combined. - The
suction opening 201 provided to thecasing body 200 is positioned at the center of thebottom part 200 a of thecasing body 200. Thesuction opening 201 is formed as a result of hollowing the center of thebottom part 200 a while leaving the outer edge part of thebottom part 200 a at approximately equal intervals. An opening of the large-diameter side of abell mouth 70 is fitted into the suction opening 201 (refer toFIG. 2 ). - The
suction opening 301 provided to thedecorative panel 300 is positioned at the center of thedecorative panel 300, and is formed in a substantial square shape. The outer edge part of thesuction opening 301 is substantially parallel to the outer edge part of thedecorative panel 300. Asuction grill 304 is provided to thesuction opening 301. Afilter 305 is mounted on thesuction grill 304 for eliminating the dust contained in the indoor air that was sucked in from thesuction opening 301 by the blower 40 (refer toFIG. 2 ). - The
blowout part 202 provided to thecasing body 200 extends in a direction along both outer edge parts between the outer edge part of thebottom part 200 a and thesuction opening 201 and formed with that direction as the lengthwise direction, and fourblowout parts 202 are provided in a manner of surrounding thesuction opening 201. Ends of theblowout part 202 have bent parts which bend in a direction of approaching each other, and the fourblowout parts 202 taken on a substantial octagon shape on the whole. - The

The fourblowout parts 302 respectively comprise aflap 303. Theflap 303 is a plate-like member that is positioned at a linear part sandwiched by the bent parts on either end of theblowout part 302, and its planar shape is formed in an elongated, substantially rectangular shape that is slightly smaller than the linear part. -
FIG. 2 is a II-II cross section ofFIG. 1 , and a diagram schematically showing the internal structure of theair conditioner 1. Thecasing body 200 internally comprises ablower 40 and aheat exchanger 60. Theblower 40 is, for example, a turbo fan that is disposed toward the upper center of thecasing body 200, sucks in indoor air from thesuction opening 301, and blows out the conditioned air that passed through theheat exchanger 60 from theblowout part 302. An opening of the small-diameter side of thebell mouth 70 is fitted into the suction side of theblower 40 in order to improve the suction efficiency of the indoor air. Theheat exchanger 60 is, for example, a cross fin tube type heat exchanger formed by being bent so as to surround the outer periphery of theblower 40, and is connected to an outdoor unit not shown, which is installed outside, via a refrigerant tube. Theheat exchanger 60 functions as an evaporator of the refrigerant flowing internally during the cooling operation, and functions a condenser of the refrigerant flowing internally during the heating operation. - The behavior, inside the
casing body 200, of the indoor air that is sucked in by theblower 40 from thesuction opening 301 and the conditioned air that is blown out by theblower 40 from theblowout part 302 is now explained. - As shown with arrow A1, the indoor that is sucked into the
casing body 200 by theblower 40 through thesuction opening 301 is guided to thebell mouth 70, and guided to theblower 40 vertically upward in parallel to the rotational axis of theblower 40. As shown with arrow B1, the indoor air that was guided to theblower 40 is blown toward theheat exchanger 60 by theblower 40 in a horizontal direction that is orthogonal to the rotational axis of theblower 40, is subject to heat exchange by theheat exchanger 60 with the refrigerant flowing inside theheat exchanger 60, and passes through theheat exchanger 60 as cooled conditioned air during the cooling operation and as heated conditioned air during the heating operation. As shown with arrow C1, the conditioned air that passed through theheat exchanger 60 descends through ablowout channel 401 formed between the inner surface of thecasing body 200 and theheat exchanger 60 and having an end as theblowout part 202, and heads toward theblowout part 202. As shown with arrow D1, the wind direction of the conditioned air that reached theblowout part 202 is changed toward the ceiling surface side by theflap 303 of theblowout part 302 opened in thedecorative panel 300 so as to oppose theblowout part 202. -
FIG. 3 toFIG. 5 are diagrams schematically showing the state of arrangement, in the decorative panel, of theflap 303, andmotor 50 serving as the drive source for oscillating theflap 303.FIG. 3 is a cross section ofFIG. 2 ,FIG. 4 is an enlarged view of part IV ofFIG. 3 , andFIG. 5 is a V-V cross section ofFIG. 4 . - A
oscillating shaft 3061 and themotor 50 are provided at the upper center part of theflap 303. Themotor 50 is supported by a support piece not shown that is protruding from an outer edge-sidevertical plane 302a (refer toFIG. 2 ) of theblowout part 302 toward the inside of theblowout part 302. Aoscillating shaft 3062 is provided, respectively, to both ends at the upper part and lengthwise direction of theflap 303. Theoscillating shaft 3061 and theoscillating shafts 3062 are disposed coaxially. - The
oscillating shaft 3061 extends in the lengthwise direction of theflap 303, and is supported by asupport piece 3071 a and asupport piece 3072 a. Thesupport piece 3071 a is positioned at either end of theoscillating shaft 3061, and protrudes upward from theflap 303. Thesupport piece 3072 a is provided in a protruding manner from thedecorative panel 300 so as to be adjacent to thesupport piece 3071 a. The protruding position of thesupport piece 3072 a is the outer edge-sidevertical plane 302 a (refer toFIG. 2 ) of theblowout part 302. - The
oscillating shaft 3062 extends in the lengthwise direction of theflap 303, and is supported by asupport piece 3071 b and asupport piece 3072 b. Thesupport piece 3071 b is positioned at one end of theoscillating shaft 3062 facing the inside of theflap 303, and protrudes upward from theflap 303. Thesupport piece 3072 b is positioned at the other end of theoscillating shaft 3062 facing the outside of theflap 303, and protrudes from thedecorative panel 300. The protruding position of thesupport piece 3072 b is the outer edge-sidevertical plane 302 a (refer toFIG. 2 ) of theblowout part 302 as with thesupport piece 3072 a. - The
support piece 3072 a supports theoscillating shaft 3061 and thesupport piece 3072 b supports theoscillating shaft 3062 rotatably around the shaft. Meanwhile, theoscillating shaft 3061 protrudes from thesupport piece 3071 a and theoscillating shaft 3062 protrudes from thesupport piece 3071 b, respectively, and thesupport piece 3071 a and theoscillating shaft 3061, as well as thesupport piece 3071 b and theoscillating shaft 3062 are respectively coupled in a fixed manner. - The
oscillating shaft 3061 comprises agear 503. Thegear 503 is mounted coaxially with and fixedly to theoscillating shaft 3061 near the middle of theoscillating shaft 3061, and rotates pursuant to the rotation of theoscillating shaft 3061. Thegear 503 engages with agear 502 that is mounted coaxially with and fixedly to arotational axis 501 of themotor 50. The rotative force generated by themotor 50 is transmitted by thegear 502 and thegear 503, and rotates theoscillating shaft 3061. Since theoscillating shaft 3061 and theoscillating shaft 3062 are disposed coaxially, theflap 303 oscillates in conjunction with the rotation of theoscillating shaft 3061. - The
motor 50, thegear 502, and thegear 503 are covered by a flow-adjustingcover 80. The outer surface of the flow-adjustingcover 80 is formed as a curved surface with a tapering upper part. Note that thesuction opening 302 side (upper side inFIG. 4 and back side of the plane of paper inFIG. 5 ) of the flow-adjustingcover 80 is formed in a notched shape so that it does not come in contact with theflap 303 during the oscillation of theflap 303. - Since the
motor 50, thegear 502, and thegear 503 are positioned on a side that is more upstream than theblowout part 302 and theflap 303 in the blowing direction of the conditioned air, the conditioned air that is blown toward theblowout part 302 is branched toward either end in the lengthwise direction of theblowout part 302 as shown with the arrow inFIG. 5 . In this embodiment, although themotor 50 is provided to the center of theblowout part 302, the conditioned air that is blown toward theblowout part 302 can be branched toward either end in the lengthwise direction of theblowout part 302 by providing to theblowout part 302 themotor 50 at a position that will be more upstream than theblowout part 302 in the blowing direction of the conditioned air by avoiding the lengthwise ends of theblowout part 302. -
FIG. 11A is a plan view showing the installed state of the air conditioner I from inside the room, and a diagram schematically showing the airflow direction of the conditioned air that is blown out from theblowout part 302 of theair conditioner 1. As described above, the conditioned air is branched toward either end in the lengthwise direction of theblowout part 302 at the center of therespective blowout parts 302. In addition, the ends of the fourblowout parts 302 are bent in a direction of approaching each other, and the blowout parts are formed in an octagon shape as a whole. Thus, the branched conditioned air is also blown out from the corner directions of thedecorative panel 300. Accordingly, the conditioned air that is blown out from the fourblowout parts 302 is blown in eight directions, with a substantially uniform wind volume and in substantially even intervals circumferentially, and will spread throughout the entire air conditioned room. - According to the
air conditioner 1 ofEmbodiment 1, since themotor 50 as well as thegear 502 and thegear 503 are covered by the flow-adjustingcover 80 without being exposed, the airflow of the conditioned air that passed through theblowout channel 401 and is blown out of theblowout part 302 will not become turbulent, and the energy efficiency of the air conditioning can thereby be improved. Accordingly, since the power consumption is reduced, it is possible to lower the electricity cost and reduce the burden on the environment. - Moreover, according to the
air conditioner 1 ofEmbodiment 1, as a result of disposing themotor 50 at the center in the lengthwise direction of theblowout part 302, the range of airflow distribution of the conditioned air can be widened in comparison to the case of disposing the motor at the end of the blowout part. In addition, unlike the conditioned air that is blown out from an auxiliary blowout part in a conventional air conditioner, the wind speed of the branched conditioned air is the same, respectively. Accordingly, the uniformity of the airflow distribution of the conditioned air can be improved, and the indoor temperature irregularity can be reduced. - An
air conditioner 2 according toEmbodiment 2 of the present invention is now explained. Note that the explanation of points that are not different fromEmbodiment 1 is omitted unless necessary.FIG. 6 is a perspective view showing the outline of theair conditioner 2 according toEmbodiment 2.FIG. 6A shows the overall view of the air conditioner andFIG. 6B shows a state where the decorative panel is removed from the casing body, and the bottom part of the casing body and the inner side of the decorative panel are exposed. Theair conditioner 2 differs from theair conditioner 1 according toEmbodiment 1 only with respect to the shape of the blowout part. In other words, ablowout part 112 of theair conditioner 2 is formed in a shape of separating theblowout part 102 of theair conditioner 1 at the center in the lengthwise direction, and in a shape that is consist of two blowingoutlets 112 a. - As shown in
FIG. 6A andFIG. 6B , as with theair conditioner 1, acasing 11 of theair conditioner 2 is configured from acasing body 210, and adecorative panel 310 that is mounted on a bottom part 210 a of thecasing body 210. Asuction opening 111 is formed by a suction opening 211 provided to thecasing body 210 and asuction opening 311 provided to thedecorative panel 310 being combined, and ablowout part 112 is formed by ablowout part 212 provided to thecasing body 210 and ablowout part 312 provided to thedecorative panel 310 being combined. These are also the same as theair conditioner 1. - A
flap 313 is provided, respectively, to the respective blowingoutlets 312 a configuring theblowout part 312 provided to thedecorative panel 310. As with theflap 303 of theair conditioner 1, theflap 313 is a plate-like member that is positioned at a linear part of theblowout part 312a, and its planar shape is formed in an elongated, substantially rectangular shape that is slightly smaller than the linear part. -
FIG. 7 andFIG. 8 are diagrams schematically showing the state of arrangement, in thedecorative panel 310, of theflap 313 and themotor 51 serving as the drive source for oscillating theflap 313.FIG. 8 is an enlarged view of part VIII ofFIG. 7 . - The
motor 51 is disposed on thedecorative panel 310 positioned between the blowingoutlets 312 a at the center of theblowout part 312. In other words, since it is not necessary to provide a support piece or the like for supporting themotor 51, the shape of theblowout part 312 configured from two blowingoutlets 312 a separated at the center in the lengthwise direction becomes a suitable shape for disposing themotor 51 at the center of theblowout part 312. - A
oscillating shaft 3161 is provided to one end on themotor 51 side and aoscillating shaft 3162 is provided to the other end at both ends at the upper part and lengthwise direction of theflap 313. Theoscillating shaft 3161 and theoscillating shaft 3162 are disposed coaxially. - The
oscillating shaft 3161 is shared by the twoflaps 313 of theblowout part 312, extends in the lengthwise direction of theflap 313, and is positioned at the center of theblowout part 312. Theoscillating shaft 3161 is supported by asupport piece 3171 a and asupport piece 3172 a. Thesupport piece 3171 a is positioned at either end of theoscillating shaft 3161 and at one end on themotor 51 side of theflap 313, and protrudes upward from theflap 313. Thesupport piece 3171 a and theoscillating shaft 3161 are fixedly coupled. Thesupport piece 3172 a is adjacent to thesupport piece 3171a, and protrudes upward from thedecorative panel 310 so as to come in sliding contact with the end of themotor 51 side of theflap 313. Thesupport piece 3172 a rotatably supports theoscillating shaft 3161. - As with the
oscillating shaft 3062 of theair conditioner 1, theoscillating shaft 3162 is supported by asupport piece 3171 b and asupport piece 3172 b. Thesupport piece 3171 b corresponds to thesupport piece 3071 b, and thesupport piece 3172 b corresponds to thesupport piece 3072 b, respectively. Agear 512 of arotational axis 511 of themotor 51 and agear 513 of aoscillating shaft 3161 are also disposed in a similar manner as theair conditioner 1. Accordingly, the mechanism of oscillating theflap 313 is also the same as theair conditioner 1. - Note that, although not shown, the
motor 51, thegear 512, and thegear 513 being covered by a flow-adjusting cover is the same asEmbodiment 1. However, unlikeEmbodiment 1, thesuction opening 312 side (upper part inFIG. 8 ) of the flow-adjusting cover does not need to be formed in a notched shape since the flow-adjusting cover and theflap 313 will not come in contact during the oscillation of theflap 313. -
FIG. 11B is a plan view showing the installed state of theair conditioner 2 from inside the room, and a diagram schematically showing the airflow direction of the conditioned air that is blown out from the respective blowingoutlets 312 a of theair conditioner 2. The conditioned air that is blown out from the eight blowingoutlets 312 a is blown in eight directions, with a substantially uniform wind speed and in substantially even intervals circumferentially, and will spread throughout the entire air conditioned room as with theair conditioner 1. - According to the
air conditioner 2 according toEmbodiment 2, it is possible to obtain a configuration that is suitable for disposing themotor 51 at the center of theblowout part 312. The other results are the same as theair conditioner 1 according toEmbodiment 1. - An air conditioner 3 according to Embodiment 3 of the present invention is now explained. Note that the explanation of points that are not different from
Embodiments air conditioner 2. The state of arrangement of aflap 323 and amotor 52 in adecorative panel 320 is shown inFIG. 9 andFIG. 10 .FIG. 10 is an enlarged view of part X ofFIG. 9 . - The air conditioner 3 comprises two
motors 52 on thedecorative panel 320 positioned between blowingoutlets 322 a at the center of ablowout part 322, and differs from theair conditioner 2 in that therespective flaps 322 respectively comprise aoscillating shaft 3261 at one end on the center side of theblowout part 322. - The
oscillating shaft 3261 is supported by asupport piece 3271 a and asupport piece 3272 a. Thesupport piece 3271 a is positioned at one end on the center side of theblowout part 322 of theflap 323, and protrudes upward from theflap 323. Thesupport piece 3271 a and theoscillating shaft 3261 are fixedly coupled, and theoscillating shaft 3261 protrudes from the surface on the center side of theblowout part 322 of thesupport piece 3271 a toward the center side of theblowout part 322. Thesupport piece 3272 a is adjacent to thesupport piece 3271 a, and protrudes upward from thedecorative panel 320 so as to come in sliding contact with the end on the center side of theblowout part 322 of theflap 323. Thesupport piece 3272 a rotatably supports theoscillating shaft 3261. - The
oscillating shaft 3261 comprises agear 523 at one end on the center side of theblowout part 322. Thegear 523 is mounted coaxially with and fixedly to theoscillating shaft 3261, and rotates pursuant to the rotation of theoscillating shaft 3261. Thegear 523 engages with agear 522 that is mounted coaxially with and fixedly to arotational axis 521 of themotor 52. The rotative force generated by themotor 52 is transmitted by thegear 522 and thegear 523, and rotates theoscillating shaft 3261. Since themotor 52 is connected to therespective flaps 323 via thegear 522 and thegear 523, the user can independently oscillate the respective flaps 323. - Note that, although not shown, the
motor 52, thegear 522, and thegear 523 being covered by a flow-adjusting cover is the same asEmbodiment 2. - According to the air conditioner 3 of Embodiment 3, since the user can independently oscillate the
respective flaps 323, the user can change the direction of the conditioned air that is blown out from the blowingoutlet 322 a for each blowingoutlet 322 a. Accordingly, if the user locally experiences a draft feeling, the user can easily resolve such draft feeling by changing, in a limited way, the blowing direction of the conditioned air. The other results are the same as theair conditioner 2 according toEmbodiment 2. - An
air conditioner 5 according to Embodiment 4 of the present invention is now explained. Note that the explanation of points that are not different fromEmbodiments 1 to 3 is omitted unless necessary.FIG. 12 is a perspective view showing the outline of theair conditioner 5 according to Embodiment 4 of the present invention. Theair conditioner 5 is a so-called single-flow type ceiling-embedded air conditioner. As with theair conditioners 1 to 3, ablower 44, aheat exchanger 64 and the like configuring theair conditioner 5 are covered by a casing 14 (refer toFIG. 13 ), and thecasing 14 is configured from acasing body 240, and adecorative panel 340 that is mounted so as to cover the entire bottom part of thecasing body 240. - The shape of the
casing 14 differs from the shape of the casings of theair conditioners 1 to 3, and thecasing body 240 is formed in an approximately rectangular shape in a planar view, and thedecorative panel 340 is formed in an approximately rectangular shape that is slightly larger than thecasing body 240 in a planar view. Theair conditioner 5 is fitted into an opening provided in the ceiling not shown in a shape according to the outer shape of a side part of thecasing body 240 extending upward from an outer edge part of the bottom part, and installed so that the front surface of thedecorative panel 340 becomes integral with the ceiling surface. This is the same as theair conditioners 1 to 3. - The
casing 14 comprises onesuction opening 141 and oneblowout part 142 at its bottom part. Thesuction opening 141 is positioned at one long side of the bottom part by extending in that long-side direction, and is formed by asuction opening 241 provided to thecasing body 240 and asuction opening 341 provided to thedecorative panel 340 being combined (refer toFIG. 13 ). As with theair conditioners 1 to 3, thesuction opening 341 is provided with asuction grill 344, and a filter not shown is mounted on thesuction grill 344. Theblowout part 142 is positioned at the other long side of the bottom part by extending in that long-side direction, its ends are formed as bent parts which are bent in a planar view (bent toward thesuction opening 341 side in this embodiment), theblowout part 142 is formed in a shape that is consist of two blowing outlets 142 a that are separated at the center in the lengthwise direction. Theblowout part 142 is formed by ablowout part 242 provided to thecasing body 240 and ablowout part 342 provided to thedecorative panel 340 being combined (refer toFIG. 13 ). - A
flap 343 is provided, respectively, to the respective blowingoutlets 342 a configuring theblowout part 342 provided to thedecorative panel 340. As with the flaps of theair conditioners 1 to 3, theflap 343 is a plate-like member that is positioned at a linear part of theblowing outlet 342 a, and its planar shape is formed in an elongated, substantially rectangular shape that is slightly smaller than the linear part. -
FIG. 13 is a XIII-XIII cross section ofFIG. 12 , and a diagram schematically showing the internal structure of theair conditioner 5. Thecasing body 240 internally comprises ablower 44 and aheat exchanger 64. Theblower 44 is, for example, a cross flow fan that is disposed above theblowout part 242, sucks in indoor air from thesuction opening 241, and blows out the conditioned air that passed through theheat exchanger 64 from theblowout part 242. Aheat exchanger 64 is disposed between thesuction opening 241 and theblower 44. - The
heat exchanger 64 is, for example, a cross fin tube type heat exchanger, is disposed obliquely from the long side part above thesuction opening 241 toward the long side part of theblowout part 242 inside thecasing body 240 in order to increase the heat exchange area, and is bent in a convex shape toward the lower side as shown inFIG. 13 so that it will not get too close to theblower 41. - The behavior, inside the
casing body 240, of the indoor air that is sucked in by theblower 44 from thesuction opening 241 and the conditioned air that is blown out by theblower 44 from theblowout part 242 is now explained. - As shown with arrow A5, the indoor air that is sucked into the
casing body 240 by theblower 44 through thesuction opening 241 is guided to theheat exchanger 64 vertically upward.
