Abstract
Description
- The present invention relates to a motor fixing device for use in an air conditioner.
- With reference to Figs. 5 and 6, this type of conventional air conditioner will be described.
- Referring to Figs.5 and 6, an indoor unit of the air conditioner will be described. The main body of the
indoor unit 101 comprises abase frame 102 shaped like a box and afront grille 105 shaped like a box attachable to thebase frame 102. - A
motor 103 disposed within thebase frame 102 drives across-flow fan 104 whereby a room air sucked through asuction port 106 formed in the top of thefront grille 105 is drawn through anair filter 107 disposed reward of thesuction port 106 and then through aheat exchanger 108 installed within thebase frame 102 where the air thus drawn is subject to heat absorption and dehumidification processes. Condensation resulting from the processes is received by adrain pan 110 disposed at adischarge grille 109 whereas the air through the heat exchange process is sent to adischarge portion 111 of thedischarge grille 109 to be discharged from adischarge port 112 formed in the bottom of thefront grille 105. - The aforesaid indoor unit is assembled through the following procedure. First,
rubber isolations 114 mounted to the opposite ends of themotor 103 are locked bymotor receiving portions 113 provided at thebase frame 102. After ashaft 116 of themotor 103 is inserted into afan boss 115 of thecross-flow fan 104, theshaft 116 is secured to thefan boss 115 by means of abolt 117. The other end of thecross-flow fan 104 is fixed with abearing 118, which is fitted into abearing portion 119 disposed at thebase frame 102. - Next, the
heat exchanger 108 is installed forward of thecross-flow fan 104 whereas mounted below theheat exchanger 108 is thedischarge grille 109 incorporating thedrain pan 110 and thedischarge portion 111. Because of alead wire 120 extending from themotor 103 locked to thebase frame 102, themotor 103 itself is aligned to position by means of a jig or the like. Then, installed forward of themotor 103 is apower board 121 incorporating electric equipments, which is secured to thebase frame 102. Thus, by mounting thepower board 121, therubber isolations 114 mounted to the opposite ends of themotor 103 are gripped between themotor receiving portions 113 of thebase frame 102 and thepower board 121. Finally, thefront grille 105 is attached to the base frame. - In the aforementioned conventional air conditioner, however, the
rubber isolations 114 of themotor 103 are locked by a pair of fixedmotor receiving portions 113 so that a slidable movement of themotor 103 is prohibited. Hence, when replacing themotor 103 at market, themotor 103 cannot be dismounted from the base frame unless thepower board 121,discharge grille 109 andcross-flow fan 104 are removed. - Additionally, when the
motor 103 is replaced at market, it is difficult to install anew motor 103 at a normal position and therefore, the installation thereof takes quite a long time. A failure to install themotor 103 at the normal position results in contact between thelead wire 120 of themotor 103 and thebase frame 102, which causes the occurrence of vibration and noise. - In view of the foregoing, it is an object of the invention to provide a motor fixing device for use in an air conditioner which provides an easy and quick replacement of the motor at market.

- Now referring to Figs.1 through 3, an embodiment of the invention will be described.
- The construction of an outdoor unit of an air conditioner is the same as the conventional example and therefore, the description thereof is omitted. An indoor unit of the air conditioner will be described with reference to Figs.1 through 3. The main body of an indoor unit 1 comprises a
base frame 2 shaped like a box and afront grille 5 shaped like a box attachable to thebase frame 2, and the like. - A cross-flow fan 4 is driven by a notor 3 installed within the
base frame 2 whereby a room air is sucked through asuction port 6 formed in the top of thefront grille 5 attached to thebase frame 2 and through an air filter 7 disposed reward of thesuction port 6. Then the air is further drawn through aheat exchanger 8 installed within thebase frame 2 so as to be subject to heat absorption and dehumidification processes. Condensation resulting from the processes is received by adrain pan 10 of adischarge grille 9 whereas an air through the heat exchanging process is sent to adischarge portion 11 of thedischarge grille 9 to be discharged from adischarge port 12 formed in the bottom of thefront grille 5. - The indoor unit is assembled through the following procedure. First, a
bearing 14 of the cross-flow fan 4 is fitted into abearing portion 13 provided at thebase frame 2. Amotor receiver 16 as a separate component (a motor receiving portion on one side) receives one (on one side of the motor) ofrubber isolations 15 mounted to the opposite ends of themotor 3 and then is mounted to thebase frame 2 while ashaft 17 of themotor 3 is inserted into afan boss 18 of the cross-flow fan 4. Therubber isolation 15 on the other side is received by amotor receiving portion 19 provided at thebase frame 2. Theshaft 17 inserted in thefan boss 18 is secured thereto by means of abolt 20. - Next, the
heat exchanger 8 is installed forward of the cross-flow fan 4. Installed below theheat exchanger 8 is thedischarge grille 9 incorporating thedrain pan 10 anddischarge portion 11. Alead wire 21 extends from themotor 3 locked by themotor receiving portion 19 on thebase frame 2 side and themotor receiver 16, and therefore, themotor 3 itself is aligned to position by means of a jig or the like. Then apower board 22 incorporating electric equipments is installed forward of themotor 3 and is secured to thebase frame 2. - Thus, by installing the
power board 22, therubber isolations 15 mounted to the opposite ends of themotor 3 are gripped between themotor receiving portion 19 and themotor receiver 16, and thepower board 22, respectively, whereby themotor 3 is secured. Finally, thefront grille 5 is attached to place. - The
motor receiver 16 is provided with claw portions comprised of a U-shaped leaf spring or the like at plural places thereon, each claw portion having aclaw 24. Eachclaw 24 is so constructed as to fit with aclaw receiver 25 provided at thebase frame 2 so that themotor receiver 16 as a separate component may be removably attached to thebase frame 2. It is to be noted that a wall at theclaw receiver 25 is eliminated so that themotor receiver 16 may be readily attached or removed. Additionally, themotor receiver 16 is formed with ahole 26, a projection or a recess. - To remove the
motor receiver 16, theaforesaid claw portion 23 is manipulated to disengage theclaw 24 from theclaw receiver 25 and then, themotor receiver 16 is pulled up with a finger inserted in thehole 26. In this manner, themotor receiver 16 on one side of the motor can be readily removed. The removal of themotor receiver 16 on one side of the motor allows a slidable movement of themotor 3 for dismounting. This provides an easy and quick operation for replacing themotor 3 at market without using tools or removing thedischarge grille 9, cross-flow fan 4 and the like. - Another embodiment of the invention will be described with reference to Fig.4.
- A
motor receiver 30, or one of the motor receiving portions provided at theaforesaid base frame 2 is formed of a part of thebase frame 2 which is cut off therefrom, and is adapted to be attached to or removed from the rest of thebase frame 2. More specifically, themotor receiver 30 is provided with a pair of grooved guidedportions 31 which are guided viagrooves 32 byguide portions 33 defined at the rest of thebase frame 2. - To remove the
motor receiver 30,claws 36 are first disengaged from the base frame to allow themotor receiver 30 to be pulled out with the grooved guidedportions 31 thereof guided by theguide portions 33. Thus, themotor receiver 30 is readily removed from the base frame. - By removing the
motor receiver 30 on one side of the motor in this manner, themotor 3 is allowed to slide for removal. Hence, an easy and quick replacement of themotor 3 at market is offered without using tools or the like, because it does not require the removal of thedischarge grille 9, cross-flow fan 4 and the like. In addition, the construction of this embodiment does not employ a separate component as one of themotor receiver 30 which is removably attached, thus reducing the number of components. Incidentally, if the grooved guidedportion 31 is provided at the rest of thebase frame 2, a same effect may be obtained. - The
aforesaid motor receiver 30 is provided with a marking 34 such that during assembly of the indoor unit or replacement of themotor 3, themotor 3 may be readily installed (set) at a normal position of design by aligning the marking 34 with a marking 35 on themotor 3. Accordingly, themotor 3 may be assembled so as to prevent thelead wire 21 of themotor 3 from contacting thebase frame 2, whereby the occurrence of vibration or noise may be avoided.
