After this, will describe the preferred embodiments of the present invention in detail with reference to the accompanying drawings.

As depicted in figs. 1 and 2, the air regulator according to the preferred embodiment of the present invention comprises housing 10, heat exchanger 20 and air blast 30, the outward appearance of these housing 10 formation air regulators; This heat exchanger 20 be placed in the housing 10 and carry out in heat exchanger 20 refrigerant and by the heat exchange between the air of housing 10, so that air is heated or is cooled; This air blast 30 produces suction and blows power, carries out heat exchange with circulating air in housing 10 and with refrigerant in heat exchanger 20.

Housing 10 has long box shape and is used as the passage of circulating air.Housing 10 comprises import 11 and outlet 12; Import 11 is formed on the downside of housing 10, is inhaled into housing 10 by this inlet air; The upside that outlet 12 is formed on housing 10 is discharged to indoor by this outlet because of the air that is heated or cooled with heat exchanger 20 heat exchanges.

Heat exchanger 20 obliquely is assemblied in the upside of housing at a certain angle, so that air carries out heat exchange simultaneously by housing 10.Air blast 30 comprise the drive motor 31 accepting electric energy and rotate power, by the rotatory force of accepting drive motor 31 produce suction and blow the blower fan 32 of power and hold blower fan 32 and air that guiding is discharged by blower fan 32 to the conduit 33 of the heat exchanger 20 that is assemblied in housing 10 upsides.

In the preferred embodiment of the present invention, blower fan 32 comprises and is used for axially air-breathing and the centrifugal fan of exhaust radially.Conduit 33 comprises having fan holding portion 33a and suction inlet 33b, the leader 33c that predetermined space is used to hold blower fan 32; This suction inlet 33b is formed on the front side of conduit, and air is inhaled into by suction inlet 33b; This leader 33c has outlet 33d, and it extends upward and be formed on the end of conduit 33 from fan holding portion 33a, is discharged from by this outlet air, and this leader is used to guide the air of being discharged by blower fan 32 to be expelled to heat exchanger 20.

Moreover, comprise back plate 10R according to the air regulator of the preferred embodiment of the present invention, form the trailing flank of housing 10, drive motor 31 is assembled on it.Back plate 10R is equipped with reinforcement 40, is used to increase the rigidity of back plate 10R to stop the outside that is transmitted to housing 10 by the magnetic noise of drive motor 31 generations.

Reinforcement 10R has predetermined length and is mounted to the back plate 10R of housing 10.Because reinforcement 40 extends up and down and its upper and lower that is fixed to back plate 10R is supported by back plate 10R, therefore after the thickness of plate 10R be increased, also be increased from the rigidity of plate 10R then.Although therefore the magnetic noise that is produced by the drive motor 31 that is assembled to back plate 10R is delivered to the back plate 10R of housing 10, yet because the rigidity of back plate 10R is increased because of reinforcement 40, the vibration of back plate 10R is reduced, therefore, the magnetic noise of drive motor 31 is reduced to the propagation of housing 10 outsides.

Moreover, because blower fan 32 is centrifugal fans and turns clockwise and blow power with generation, so the air quantity of discharging by the right part of outlet 12 is greater than the air quantity of discharging by the left part of outlet 12.Therefore, there are differences by the flow velocity that exports the air that 12 right part and left part discharge.

Therefore, reinforcement 40 is manufactured to have the tabular of preset width.Reinforcement 40 is fixed among the outlet 33d of conduit 33, be substantially perpendicular to the inner surface of housing 10 back plate 10R, so that the air that conduit 33 is discharged is assigned to the right part and the left part of outlet 12, make by the flow velocity that exports the air that 12 right part and left part discharge even.

For this reason, reinforcement 40 integrally extends to the rear side of conduit 33 from the inner surface of the leader 33c of conduit 33, and, the rear side of reinforcement 40 is fixed to the inner surface of the back plate 10R of housing 10, as shown in Figure 3, be divided into right part and left part and uniform distribution by the air of outlet 33d with inside, so that discharged more equably by exporting 12 air quantities of discharging to right part and left part discharge with leader 33c.In a preferred embodiment of the invention, the part of reinforcement 40 is protruded above the outlet 33d of conduit 33, and has enough length, so that afterwards the rigidity of plate 10R is increased, and the air of discharging by outlet 33d is guided continuously by reinforcement 40.

Moreover reinforcement 40 has convex and female flank surface, the air of discharging with guiding smoothly, and increase the rigidity of the vertical and horizontal direction of back plate 10R.

Following table be presented in the experiment air regulator of reinforcement 40 never and have that the air regulator of reinforcement 40 measures at outlet 12 right parts and the noise at left part place, the flow velocity of air.
