- the unit main body 110 has a box-shaped housing 111 formed of a steel plate .
- the outer wall surface of the housing 111 is provided with plural suspending tags 112 connected to suspending bolts (not shown) secured to the ceiling beams, and the unit main body 110 is mounted in the ceiling space of a room to be air-conditioned by the suspending tags 112.
- the face panel 120 has a substantially rectangular exterior appearance larger than the housing 111 of the unit main body 110, and secured to the ceiling 104 so as to close a ceiling hole 105 when the unit main body 110 is inserted into the ceiling 104. Furthermore, an air suction port 121 for sucking air in the room to be air-conditioned is formed along one side edge portion in the longitudinal direction of the face panel 120, and an air blowing port 122 is formed along the other side edge portion.
- a suction grille 124 supporting a filter 123 is freely detachably disposed at the air suction port 121 of the face panel 120, and a flap 125 extending in the width direction of the face panel 120 is disposed at the air blowing port 122 of the face panel 120.
- the flap 125 is supported to be swingable around a shaft 126 as a supporting point by driving a motor (not shown) .
- the face panel 120 has detachable side panels 127 which are disposed so as to face the suspending tags 112 of the housing 111, and when the side panel 127 is detached, the suspending tags 112 are exposed, and a worker can adjust the height of the unit main body 110 from the indoor.
- the unit main body 110 is provided with a partition plate for partitioning the internal space of the housing 11 into a machine room 130 and a heat exchange room 131.
- the air blower 102 and an electric component box 106 are disposed in the machine room 130, and a heat exchanger 103 and a refrigerant pipe 107 connected to the heat exchanger 103 are disposed in the heat exchanger 131.
- the refrigerant pipe 107 constitutes a refrigerant feed pipe for feeding refrigerant supplied from an outdoor unit (not shown) to the heat exchanger 103, and a part of a refrigerant return pipe for returning refrigerant circulated in the heat exchanger 103 to the outdoor unit.
- the air blower 102 is equipped with two fan units 136 in which multiblade fans 135 are respectively mounted, and a motor 137 for rotationally driving the multifans 135 of the respective fan units 136.
- the motor 137 is driven on the basis of a driving signal from a control board mounted in the electric component box 106, and as shown in Fig. 10 , air in the room to be air-conditioned is sucked through the air suction port 121 of the face panel 120 so that the indoor air cleaned by the filter is blown to the heat exchange room 131.
- the heat exchanger 103 is applied to a fin-tube type heat exchanger, and it is disposed obliquely (tilt arrangement) in the heat exchange room 131.
- a drain pan of expanded polystyrene is disposed at the lower side of the heat exchanger 103 so that dew condensation water of the heat exchanger 103 does not leak to the room to be air-conditioned, and also the drain pan 138 serves as a part of a heat insulating member for thermally insulating the heat exchanger 103.
- the heat exchanger 131 is thermally insulated by not only the drain pan 138, but also a heat insulating member 140 of expanded polystyrene disposed along the inner wall surface of the housing 111.
- the indoor air in the room to be air-conditioned is sucked from the air suction port 121 of the face panel 120 through the filter 123 into the unit main body 110 by the air blower 102 as indicated by an arrow of Fig. 10 , and then blown to the heat exchanger 103 to be heat-exchanged by the heat exchanger 103. Thereafter, the indoor air impinges against the inner wall surface 110A of the unit main body 110, and it is deflected to the substantially orthogonal direction and blown from the air blowing port 122 of the face panel 120. Accordingly, the indoor air is circulated in the heat exchanger 103 of the unit main body 110, whereby adjustment of the indoor temperature (indoor air conditioning) can be performed.
- an air blowing duct 150 ( Fig. 13 ) is selectively connected to the side wall 111X of the housing 111 of the unit main body 110 in accordance with a user's demand or the like, and air-conditioned air which has been heat-exchanged in the heat exchanger 103 is allowed to be blown to the room to be air-conditioned through the air blowing duct 150.
- air blowing duct 150 As shown in Fig. 13
- knockout holes 160 are formed along the edge portion of a duct-planed port D of the air blowing duct 150 in the outer wall surface (connection-planed surface) 111A of the side wall 111X to which the air blowing duct 150 will be connected so that the knockholes 160 are spaced from one another, and the members among the knockout holes 160 are cut out so that the knockout holes 160 intercommunicate with one another, whereby a duct port D0 ( Fig. 14, Fig. 15 ) of the air blowing duct 150 can be easily formed.
- duct-planed ports D1 to D4 which are symmetrically arranged on two vertical columns and two lateral lines are assumed as the duct-planed port D, and the knockout holes 160 each having a slender hole shape are formed along the edge portions of the respective duct-planed ports D1 to D4 so as to be spaced from one another.
- the knockout holes 160 along the lower edge portion of the upper duct-planed port D1 serve as the knockout holes 160 along the upper edge portion of the lower duct-planed port D2. Accordingly, as compared with the case where the knockout holes 160 are formed so that the duct-planed ports D1 and D2 are spaced from each other, the number of knockout holes can be reduced, and the load of processing the knockout holes can be reduced.
- the knockout holes 160 along the edge portion of one duct-planed port D3 serve as the knockout holes 160 along the edge portion of the other duct-planed port D4, and the load of processing the knockout holes 160 can be reduced.
- the heat insulating member 140 is disposed inside the knockout holes 160. Therefore, outside air is prevented from invading through the knockout holes 160 into the unit main body 110 by the heat insulating member 140, and thus the heat insulation in the unit main body 110 is kept.
- Fig. 13 is a perspective view showing an example of the air blowing duct 150.
- the air blowing duct 150 comprises a metal housing 151 connected to the unit main body 110 of the air conditioner 100, a metal housing 152 intercommunicating with an opening (blowing duct air sending port) provided to the ceiling or the like, and a connecting member 152 that connects the housings 151 and 152 and is formed of flexible material.
- the orientation of one housing 153 can be changed in any direction with respect to the other housing 152 by the connecting member 153.
- a flange 154 extending inwardly is provided to an opening portion 151A of the housing 151.
- Plural pinholes 155 are provided to the flange 154, and hook members 156 are connected to the flange portion 154 by pins so as to be spaced from one another.
- the hook member 156 is formed by bending a metal plate member in a substantially U-shape, and it is designed so that the U-shaped portion thereof is hooked to the unit main body 110.
- the hook member 156 can temporarily support the opening portion 151A side of the air blowing duct 150 to the fixing position of the unit main body 110 by hooking the U-shaped portions to the unit main body 110.
- Figs. 14 and 15 is a partially cross-sectional view showing the state that the air blowing duct 150 is connected to the unit main body 110 of the air conditioner 100.
- any one or more of the duct-planed ports D1 to D4 of the unit main body 110 are opened as the duct port D0, and also a part of the heat insulating member 14 which shields the duct port D0 is cut out so that the duct port DO and the heat exchange room 131 intercommunicate with each other.
- the hook members 156 of the air blowing duct 150 are drawn out and hooked to the lower edge portion D0L of the duct port D0 of the unit main body 110 through a heat insulating cushion member 157 to keep the duct port side of the air blowing duct 150 under a floated state, and the air blowing duct 150 is positioned under the floated state and connected by pins. Therefore, if the duct port side of the air blowing duct 150 can be once lifted up, the duct port side can be temporarily fitted by the hook members 156 while floated, and the connecting work of the air blowing duct 150 can be facilitated.

Description
- The present invention relates to an air conditioner.
- There has been hitherto known an in-ceiling mount type air conditioner that is mounted in the ceiling of a room to be air-conditioned and has a unit main body (the main body of the air conditioner) containing a heat exchanger and an air blower accommodated in a substantially box-shaped housing. In this type of in-ceiling mount type air conditioner, a face panel having an air blowing port is secured to the lower surface side of the unit main body by screws (for example. See Patent Document 1) . Furthermore, there are also known in-ceiling mount type air conditioners in which a duct port is provided on the side surface of the unit main body, and air-conditioned air is blown from the air blowing port through an air blowing duct connected to the duct port. In some of this type of air conditioners each having the air blowing duct, a rotatable disc is disposed in the duct port and the air blowing amount to the air blowing duct is adjustable by the disc (for example, see Patent Document 2) .
Patent Document 1:JP-A-2003-194394
Patent Document 2: JP-UM-A-7-22344
JP 7022344 U - The construction that the disc for adjusting the air blowing amount is disposed at the duct port has a problem that the number of parts is increased and the fabrication is more cumbersome. With respect to in-ceiling mount type air conditioners each of which is equipped with a face panel having an air suction port and an air blowing port, it has been recently required by users that an air blowing duct is connected, and air-conditioned air can be blown from both or one of the air blowing duct and the air suction port of the face panel. In this case, in order to make it easy to secure an air blowing duct afterwards, the in-ceiling mount type air conditioner is further required to be designed so that the air blowing amount can be easily adjusted when the air blowing duct is connected.
- Therefore, an object is to provide an air conditioner that can easily adjust the amount of air to be blown to an air blowing duct without increasing the number of parts even when the air blowing duct is secured afterwards.
- An air conditioner according to
claim 1 has a unit main body that is mounted in the ceiling of a room to be air-conditioned and contains a heat exchanger and an air blower in a substantially box-shaped housing, an air blowing duct being selectively connected to the housing, and knockout holes along edge portions of four opening-planed ports that can selectively intercommunicate with the air blowing duct are formed so as to be spaced from one another. According to the above construction, knockout holes along edge portions of plural opening-planed ports that can selectively intercommunicate with the air blowing duct are formed on the connection-planed face of the air blowing duct in the housing so as to be spaced from one another. Therefore, even when the air blowing duct is afterwards assembled, the air flow amount to the air blowing duct can be easily adjusted. - In this case, some of knockout holes along the edge portions of the opening-planed ports also may serve as some of the knockout holes along the edge portion of the other opening planted ports. Furthermore, a heat insulating member may be disposed in the housing, and the heat insulating member may prevent invasion of outdoor air through the knockout holes into the housing. Furthermore, a face grille that is secured to the ceiling surface and has an air blowing port and air suction port may be further provided.
- The knockout holes along the edge portion of the plural opening planed ports that can selectively intercommunicate with the air blowing duct are formed on the connection planed surface of the air blowing duct in the housing so as to be spaced from one another. Therefore, even when the air blowing duct is afterwards assembled, the air blow amount to the air blowing duct can be easily adjusted without increasing the number of parts.
- Embodiments of the present invention will be described hereunder in detail with reference to the drawings.

As shown inFig. 5 , aheat exchanger 60, adrain pan 62, etc. are disposed in theheat exchange room 42. - Here, the construction of the
side panels side panel 19A and theside panel 19B have a symmetrical shape, and thus in the following description, theside panel 19A will be described.Fig. 7 is a perspective view showing the exterior appearance of the back side of theside panel 19A. Theside panel 19A is roughly equipped with amain plate portion 90 having a substantially flat-plate shape, and asub plate portion 91 located at the upper side of themain plate portion 90. Themain plate portion 90 is provided withfitting portions portion 81A of theface panel 3, afitting portion 93 fitted to a fitting and receivingportion 81B of theface panel 3, afitting portion 94 fitted to a fitting and receivingportion 81C of theface panel 3, afitting portion 95 fitted to a fitting and receivingportion 81E of theface panel 3, and afitting portion 96 fitted to a fitting and receivingportion 81F of theface panel 3. - The

Fig. 9 is a perspective view showing the construction of the exterior appearance of an in-ceiling mount type air conditioner (hereinafter referred to as air conditioner) according to a second embodiment, andFig. 10 is a cross-sectional view showing theair conditioner 100. Theair conditioner 100 has a unit main body (the main body of the air conditioner) 110 for accommodating anair blower 102 and aheat exchanger 103, and aface panel 120 fixed to the lower portion of the unitmain body 110 by screws . The unitmain body 110 has a box-shapedhousing 111 formed of a steel plate . The outer wall surface of thehousing 111 is provided with plural suspendingtags 112 connected to suspending bolts (not shown) secured to the ceiling beams, and the unitmain body 110 is mounted in the ceiling space of a room to be air-conditioned by the suspending tags 112. - The
face panel 120 has a substantially rectangular exterior appearance larger than thehousing 111 of the unitmain body 110, and secured to theceiling 104 so as to close aceiling hole 105 when the unitmain body 110 is inserted into theceiling 104. Furthermore, anair suction port 121 for sucking air in the room to be air-conditioned is formed along one side edge portion in the longitudinal direction of theface panel 120, and anair blowing port 122 is formed along the other side edge portion. - A
suction grille 124 supporting afilter 123 is freely detachably disposed at theair suction port 121 of theface panel 120, and aflap 125 extending in the width direction of theface panel 120 is disposed at theair blowing port 122 of theface panel 120. Theflap 125 is supported to be swingable around ashaft 126 as a supporting point by driving a motor (not shown) . As shown inFig. 9 , theface panel 120 hasdetachable side panels 127 which are disposed so as to face the suspendingtags 112 of thehousing 111, and when theside panel 127 is detached, the suspendingtags 112 are exposed, and a worker can adjust the height of the unitmain body 110 from the indoor. - As shown in
Figs. 10 and11 , the unitmain body 110 is provided with a partition plate for partitioning the internal space of the housing 11 into amachine room 130 and aheat exchange room 131. Theair blower 102 and anelectric component box 106 are disposed in themachine room 130, and aheat exchanger 103 and arefrigerant pipe 107 connected to theheat exchanger 103 are disposed in theheat exchanger 131. Therefrigerant pipe 107 constitutes a refrigerant feed pipe for feeding refrigerant supplied from an outdoor unit (not shown) to theheat exchanger 103, and a part of a refrigerant return pipe for returning refrigerant circulated in theheat exchanger 103 to the outdoor unit. - The
air blower 102 is equipped with twofan units 136 in whichmultiblade fans 135 are respectively mounted, and amotor 137 for rotationally driving themultifans 135 of therespective fan units 136. Themotor 137 is driven on the basis of a driving signal from a control board mounted in theelectric component box 106, and as shown inFig. 10 , air in the room to be air-conditioned is sucked through theair suction port 121 of theface panel 120 so that the indoor air cleaned by the filter is blown to theheat exchange room 131. - The
heat exchanger 103 is applied to a fin-tube type heat exchanger, and it is disposed obliquely (tilt arrangement) in theheat exchange room 131. A drain pan of expanded polystyrene is disposed at the lower side of theheat exchanger 103 so that dew condensation water of theheat exchanger 103 does not leak to the room to be air-conditioned, and also thedrain pan 138 serves as a part of a heat insulating member for thermally insulating theheat exchanger 103. Theheat exchanger 131 is thermally insulated by not only thedrain pan 138, but also aheat insulating member 140 of expanded polystyrene disposed along the inner wall surface of thehousing 111. - With the above construction, in the
air conditioner 100, the indoor air in the room to be air-conditioned is sucked from theair suction port 121 of theface panel 120 through thefilter 123 into the unitmain body 110 by theair blower 102 as indicated by an arrow ofFig. 10 , and then blown to theheat exchanger 103 to be heat-exchanged by theheat exchanger 103. Thereafter, the indoor air impinges against theinner wall surface 110A of the unitmain body 110, and it is deflected to the substantially orthogonal direction and blown from theair blowing port 122 of theface panel 120. Accordingly, the indoor air is circulated in theheat exchanger 103 of the unitmain body 110, whereby adjustment of the indoor temperature (indoor air conditioning) can be performed. - In the
air conditioner 100 described above, an air blowing duct 150 (Fig. 13 ) is selectively connected to theside wall 111X of thehousing 111 of the unitmain body 110 in accordance with a user's demand or the like, and air-conditioned air which has been heat-exchanged in theheat exchanger 103 is allowed to be blown to the room to be air-conditioned through theair blowing duct 150. In this embodiment, as shown inFig. 12 , knockout holes 160 are formed along the edge portion of a duct-planed port D of theair blowing duct 150 in the outer wall surface (connection-planed surface) 111A of theside wall 111X to which theair blowing duct 150 will be connected so that theknockholes 160 are spaced from one another, and the members among the knockout holes 160 are cut out so that the knockout holes 160 intercommunicate with one another, whereby a duct port D0 (Fig. 14, Fig. 15 ) of theair blowing duct 150 can be easily formed. - More specifically, in this embodiment, as shown in
Figs. 12 , four duct-planed ports D1 to D4 which are symmetrically arranged on two vertical columns and two lateral lines are assumed as the duct-planed port D, and the knockout holes 160 each having a slender hole shape are formed along the edge portions of the respective duct-planed ports D1 to D4 so as to be spaced from one another. Here, with respect to the duct-planed ports D1 and D2 arranged in the vertical direction, the knockout holes 160 along the lower edge portion of the upper duct-planed port D1 serve as the knockout holes 160 along the upper edge portion of the lower duct-planed port D2. Accordingly, as compared with the case where the knockout holes 160 are formed so that the duct-planed ports D1 and D2 are spaced from each other, the number of knockout holes can be reduced, and the load of processing the knockout holes can be reduced. - With respect to the duct-planed ports D3 and D4 arranged in the vertical direction, as in the case of the duct-planed knockout holes D1 and D2, the knockout holes 160 along the edge portion of one duct-planed port D3 serve as the knockout holes 160 along the edge portion of the other duct-planed port D4, and the load of processing the knockout holes 160 can be reduced. As described above, the
heat insulating member 140 is disposed inside the knockout holes 160. Therefore, outside air is prevented from invading through the knockout holes 160 into the unitmain body 110 by theheat insulating member 140, and thus the heat insulation in the unitmain body 110 is kept. -
Fig. 13 is a perspective view showing an example of theair blowing duct 150. Theair blowing duct 150 comprises ametal housing 151 connected to the unitmain body 110 of theair conditioner 100, ametal housing 152 intercommunicating with an opening (blowing duct air sending port) provided to the ceiling or the like, and a connectingmember 152 that connects thehousings housing 153 can be changed in any direction with respect to theother housing 152 by the connectingmember 153. Aflange 154 extending inwardly is provided to anopening portion 151A of thehousing 151.Plural pinholes 155 are provided to theflange 154, andhook members 156 are connected to theflange portion 154 by pins so as to be spaced from one another. Thehook member 156 is formed by bending a metal plate member in a substantially U-shape, and it is designed so that the U-shaped portion thereof is hooked to the unitmain body 110. Thehook member 156 can temporarily support theopening portion 151A side of theair blowing duct 150 to the fixing position of the unitmain body 110 by hooking the U-shaped portions to the unitmain body 110. -
Figs. 14 and 15 is a partially cross-sectional view showing the state that theair blowing duct 150 is connected to the unitmain body 110 of theair conditioner 100. As shown inFigs. 14 and 15 , when theair blowing duct 150 is connected to the unitmain body 110, any one or more of the duct-planed ports D1 to D4 of the unitmain body 110 are opened as the duct port D0, and also a part of theheat insulating member 14 which shields the duct port D0 is cut out so that the duct port DO and theheat exchange room 131 intercommunicate with each other. Thereafter, female screw holes are formed at the positions corresponding to the pin holes 55 of theair blowing duct 150 on the connection-planedsurface 111A of the unitmain body 110, and theair blowing duct 150 is pin-fastened to the female screw holes through the pine holes 155, whereby theair blowing duct 150 is connected to the unitmain body 110. In this case, in order to make the air flow amount blown from theair blowing duct 150 equal between the right and left sides, it is preferable that when the duct-planed port D1 is set to the duct port D0, the duct-planed port D3 is also set to the duct port D0. Likewise, it is preferable that when the duct-planed port D2 is set to the duct port D0, the duct-planed port D4 is set to the duct port D0. - When the
air blowing duct 150 is connected to the unitmain body 110 as described above, thehook members 156 of theair blowing duct 150 are drawn out and hooked to the lower edge portion D0L of the duct port D0 of the unitmain body 110 through a heat insulatingcushion member 157 to keep the duct port side of theair blowing duct 150 under a floated state, and theair blowing duct 150 is positioned under the floated state and connected by pins. Therefore, if the duct port side of theair blowing duct 150 can be once lifted up, the duct port side can be temporarily fitted by thehook members 156 while floated, and the connecting work of theair blowing duct 150 can be facilitated. The heat insulatingcushion member 157 is formed of a heat insulating member having cushion property to be embedded in the gap between theair blowing duct 150 and the unitmain body 110, and it is formed of polyethylene, for example, By inserting the heat insulatingcushion member 157 between theair blowing duct 150 and the unitmain body 110, the gap between theair blowing duct 150 and the unitmain body 110 can be perfectly shielded and also sufficient heat insulation can be performed. - As shown in
Fig. 14 , when only the duct-planed ports D2 and D4 of the unitmain body 110 are set to the duct port D0, the air flow amount to be supplied to theair blowing duct 150 can be set to a small value, and thus the distribution rate of the air-conditioned air supplied to theair blowing duct 150 and theair blowing port 122 of theface panel 120 can be set to be larger at theair blowing port 122 side. - On the other hand, when all the duct-planed ports D1 to D4 of the unit
main body 110 are set to the duct port D0, the opening area of the duct port D0 is set to be larger than the case ofFig. 14 , and thus the air flow amount to be supplied to theair blowing duct 150 can be increased. Therefore, the distribution rate of the air-conditioned air supplied to theair blowing duct 150 and theair blowing port 122 of theface panel 120 can be set to be larger at theair blowing duct 150 side. - In this embodiment, the knockout holes 160 located along the edge portions of the plural duct-planed ports D1 to D4 are formed in the
housing 111 so as to be spaced from one another, and the duct-planed ports D1 to D4 are selectively opened and set to the duct port D0. Therefore, the air flow amount supplied to theair blowing duct 150 can be adjusted, and the distribution rate of the air-conditioned air supplied to theair blowing duct 150 and theair blowing port 122 of theface panel 120 can be freely adjusted. - Furthermore, when the duct port D0 is formed, it is sufficient only to selectively cut out the knockout holes 160 formed in the
housing 111. Therefore, as compared with the prior art having a disc for adjusting the air flow amount to the air blowing duct, the air flow to the air blowing duct can be more easily adjusted without increasing the number of parts, and the air blowing duct can be afterwards assembled. Theair conditioner 100 may be designed so that when theair blowing duct 150 is connected, the air conditioner, theair blowing port 122 of theface panel 120 is closed by a closing member and the air-conditioned air is blown from only theair blowing duct 150. - The embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, and various modifications may be made. For example, in the first embodiment, the
pocket portion 99 is constructed as the hermetically accommodating portion for accommodating the portion exposed to theside panel 19A side of thescrew 80B as a fixing member while the portion concerned is substantially hermetically sealed. However, it may be modified so that the head portion of the screw is located in a recess portion, the recess portion concerned is sealed by a lid member so that the lid member is detachable from the recess portion, and the hermetically accommodating portion is constructed by the recess portion and the lid member. Likewise, the shape of thepocket portion 99 is not limited to the box-shape like this embodiment, but various shapes such as a cylindrical shape, etc. may be applied. - In the second embodiment, which does not form part of the claimed invention, the knockout holes 160 which can easily open the four duct-planed ports D1 to D4 arranged in the two vertical columns and two lateral lines are formed in the unit
main body 110 in advance. However, the number and shape of the duct-planed ports may be arbitrary. For example, knockout holes corresponding to duct-planed ports D1 to D4 arranged four lateral lines which are symmetrical with respect to the right and left sides may be formed as shown inFig. 16 . In this case, when the air blowing amount of theair blowing duct 150 is reduced, the duct-planed ports D2 and D3 may be set to the duct port D0, and when the air blowing amount is increased, all the duct-planed ports D1 to D4 may be opened and set to the duct port D0. Furthermore, the shape of the knockout holes is not limited to the slender hole shape, and various hole shapes such as a round hole, etc. may be applied. -
