The specific embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The air conditioner that the present invention is suitable for as shown in Figure 3, has: box-shaped body 10 is provided with in the inside of main body 10 and carries out the air-blast device that general heat exchanger 13 that heat exchange uses and fluid air blast are used.In addition,,, form air entry 11, be formed for the air through overregulating is discharged to once more the exhaust outlet 12 of the interior space at upside at downside for room air being drawn into the inside of main body 10 in the place ahead of main body 10.
The air-blast device of main body 10 inside has: by the air blast 14 that common multiple wing type centrifugal blower constitutes, make it to have passed through the force air ground air blast of heat exchanger 13 to exhaust outlet 12 sides with flowing into air entry 11; Make the motor 15 of these air blast 14 rotations; And the fan shroud 20 that on every side air flow is led that is located at air blast 14.For this air-blast device is set, at the inner surface of main body 10 motor mounting plate 16 is set, make it motor 15 can be installed, fastening by a plurality of trip bolts 17 is fixed on motor 15 on the motor mounting plate 16.In addition, air blast 14 is combined on the rotating shaft 15a of motor 15.
Fan shroud 20 forms cylindric, makes it to hold air blast 14, forms inlet 20a respectively with the rear forwardly, and 20b passes air into the both sides of cfentrifugal blower 14 and from the top discharge, forms outlet 20c on top.In addition, fan shroud 20 constitutes as follows,, considers the manufacturing of fan shroud 20 and the situations such as installation of air blast 14 that is, and the cap 21 of the inlet 20a formation of front side can freely be separated with the casing portion 22 that the inlet 20b of rear side forms with loading and unloading.The structure of this fan shroud 20, when having considered air blast 14 rotations, air flows into along the characteristic of the cfentrifugal blower 14 of radial direction air blast from its central authorities, can be directed to exhaust outlet 12 sides on top along the air of radial direction air blast.
In addition, dividing plate 23 is set, makes it to keep the top of fan shroud 20, distinguish the upper space and the lower space of main body 10 simultaneously, make air only flow to exhaust outlet 12 sides on the top of fan shroud 20.At this moment, dividing plate 23 was arranged with fan shroud in 20 minutes, then fan shroud 20 was combined on the dividing plate 23, also can fan shroud 20 and dividing plate 23 be manufactured one by common plastic injection-moulded shaping.In addition, in the bottom at casing portion 22 back sides of fan shroud 20 fan shroud fixture 30 is set, it is stably fixing to make it the fan shroud 20 that can separate the inner surface by main body 10.
At this moment, for the air flow resistance that makes the inlet 20b that flows into fan shroud 20 rear sides minimizes, only the downside central portion in the casing portion 22 of fan shroud 20 is provided with a holding member 31, and its outer surface is made of common tubular surface.In addition, as shown in Figure 5, around combined hole 33, for can be securely in conjunction with holding member 31, the end of holding member 31 enters given depth, form the holding section 34 of engaging simultaneously, this holding section 34 from the back side of fan shroud casing portion 22 with corresponding to the recessed given depth that is provided with of the size of holding member 31 end areas.
Through this fan shroud fixture 30 fixedly during fan shroud 20, holding member 31 is placed on the holding section 34, the hollow bulb 31a that runs through combined hole 33 and holding member 31 from the inside of fan shroud 20, attaching parts 32 are inserted, also can be connected to these attaching parts 32 on the connecting hole 16a of the motor mounting plate 16 that is located at main body 10 inner surfaces.
This structure is simplified the structure of fan shroud 20 by fan shroud 20 and holding member were arranged in 31 minutes, thereby the manufacturing of the fan shroud 20 by common plastic injection-moulded shaping manufacturing can be saved the manufacturing cost of fan shroud 20 whereby more than easy in the past.In addition, this structure can reduce the flow resistance of air by the holding member 31 that an outer surface only is set is curved surface, reduces noise, strengthens the blow rate required, by the connection of attaching parts 32 fan shroud 20 is fixed, and becomes easy thereby install.
As mentioned above, by being provided for the fixedly holding member of the fan shroud of air conditioner of the present invention respectively, thereby simplified the structure of fan shroud, thereby the manufacturing of fan shroud becomes more than easy in the past.
In addition, air conditioner of the present invention is only established a holding member that supports fan shroud, and the outer surface of holding member is made of curved surface, thereby not only reduces the flow resistance of air, reduces noise, strengthens the blow rate required, and has easy-to-install effect.
