The specific embodiment
Below, an embodiment to the indoor unit of air conditioner of the present invention describes with reference to accompanying drawing.
Fig. 1 is the longitudinal sectional view of indoor unit of the air conditioner of one embodiment of the invention.
As shown in Figure 1, the indoor unit 1 of the air conditioner of present embodiment has framework 2, and this framework 2 is made of front panel 3 and backboard 4.
The front surface of front panel 3 is provided with intake panel (suction panel) 3a.Make the lower openings of this intake panel 3a form bottom suction inlet 3b.The upper surface of front panel 3 embeds top grid (upper panel) 5, makes grid 5 openings formation top suction inlet 3c above this.Make the lower openings of front panel 3 form blow-off outlet 3e with shutter (louver) 3d.
In framework 2, relatively dispose electric vacuum cleaner 6 with intake panel 3a.The below of this electric vacuum cleaner 6 is provided with display part 7.And, dispose the heat exchanger 8 that forms V word shape in the leeward of electric vacuum cleaner 6.
This heat exchanger 8 comprises: make the front side heat exchanger 8A that passes through from bottom suction inlet 3b and top suction inlet 3c inhaled air and make the rear side heat exchanger 8B that passes through from top suction inlet 3c inhaled air.
In addition, between heat exchanger 8 and blow-off outlet 3e, be formed with ventilation channel 9.Dispose air blast 10 below the heat exchanger 8 in this ventilation channel 9.
This air blast 10 comprises: cross flow fan shown in Figure 5 (cross-flow fan) 11 and the fan motor 12 with lead 12a shown in Figure 7,, with after the air suction and making it heat exchanger 8, carry out heat exchange air is blown out from blow-off outlet 3e by ventilation channel 9 from suction inlet 3b, 3c.
As shown in Figures 2 and 3, fan motor 12 uses and is fixed in backboard 4 across the motor hoop 14 of vibrationproof valve rubber (rubber cushion) 13 ground clamping motor side protuberance 12b and the motor case hoop (motor housing band) 15 of clamping motor case (motor housing) 12c.
As shown in Figure 4, motor hoop 14 comprises: lower motor hoop 16 and utilize hinge portion (hingeportion) but top motor hoop 17 that 14a is connected with these lower motor hoop 16 free bending ground.
On the other hand, with after the component parts combination, indoor blower 10 is installed in the framework 2 as illustrated in fig. 5.In addition, the arrow among Fig. 5 is represented combination, the assembling sequence of each component parts.
For example, indoor blower 10 comprises: cross flow fan 11 that width and heat exchanger 8 are identical and the fan motor 12 that is connected with the end plate 11a of a lateral side of this cross flow fan 11.Bolster (not shown) pivot on the end plate 11b of outstanding the other side that is arranged on cross flow fan 11 props up on the bearing 18a of supporting member 18, and indoor blower 10 is contained among the bearing installation portion 4a of backboard 4.
In addition, motor case 12c is housed in the installation recess 4b that is arranged at backboard 4, and utilizes the motor case hoop 15 of the clamping recess 15a that is provided with semicircle shape to be fixed in backboard 4.In addition, motor side protuberance 12b utilizes the 14a of hinge portion shown in Figure 4 and spiral snap- latch piece 16d, 17d to be clamped between lower motor hoop 16 and the top motor hoop 17 across vibrationproof valve rubber 13 ground, in addition, motor hoop 14 is installed on backboard 4 with 2 engaging pawl 16e, 16e and is disposed in the ventilation channel 9 of framework 2.
As Figure 6 and Figure 7, the end face crested plate 17c of the motor drive shaft 12d that exposes from the side of motor side protuberance 12b covers with state separated by a distance.And, being formed with broader space s around this shield 17c, can dispel the heat for motor.In addition, from the extended lead 12a in fan motor 12 sides by keeping at a certain distance away with shield 17c and being positioned at the lead guide plate 16c supporting and the guiding in its outside, therefore, can prevent that lead 12a from contacting with the end face of the motor drive shaft 12d that shows out in motor-side.Therefore, can make lead 12a can not sustain damage and the situation of heat affecting under guide to electric installing component (not shown) safely.Therefore, need not to avoiding lead 12a and contacting of fan motor to make lead 12a walk around fan motor 12, thereby can improve the property produced in batches and reduce manufacturing cost.
As indicated above, the present invention can realize a kind ofly being convenient to produce in batches and the indoor unit of air conditioner cheap for manufacturing cost.
