Definitions
- the present invention relates to an indoor unit for an air conditioner, which employs a turbo fan for blowing out sucked air radially outwardly relative to an axis thereof.
- an indoor unit for an air conditioner in which a cross-fin heat exchanger and a cross flow fan are disposed within a generally rectangular casing mounted on a wall surface, where air-conditioning air is blown out from an air outlet provided at the underside of the casing.
- this indoor unit for an air conditioner is largely projected from the wall surface, incapable of being thinned in depth, thus having a drawback that the indoor unit does not fit indoor interior.
- the present applicant manufactured an indoor unit for an air conditioner capable of improving the indoor interior properties by being thinned.
- This indoor unit for an air conditioner includes a heat exchanger having an axis oriented along the back and forth direction within the casing, and a turbo fan which is placed on the back side of the heat exchanger within the casing and which serves for blowing out air, sucked from the front side, radially outwardly relative to the axis of the turbo fan. Then, air outlets for blowing out air in four directions, up and down, right and left, are provided in the casing . As the turbo fan is rotated, the indoor unit blows out air, sucked through an air inlet on the front side, in four directions from the individual air outlets.
- the flow of air blown out from the turbo fan is controlled by a planar vane and a plurality of curved vanes mounted to the air outlets of the casing, whereas the air blown out from the turbo fan is blown out on the front side in the rotational direction of the turbo fan and about 40-degree outward with respect to a tangent to the outer circumference of the turbo fan.
- air is not blown out in a direction along a plane generally perpendicular to the longitudinal direction of the air outlets of the casing, posing a problem that desired air flow characteristics cannot be obtained.
- the incident angle of the air flow on the vane surfaces of the curved vanes on the rear side becomes larger so that separation flows of air would occur.
- the curved surfaces of the curved vanes are uniformized in configuration so that the air is blown out in a direction along a plane generally perpendicular to the longitudinal direction of the air outlets on the rear side in the rotational direction of the turbo fan, the incident angle of the air flow on the vane surfaces of the curved vanes on the front side becomes larger so that separation flows of air would occur. This poses problems that the air flow is not efficiently regulated, and that noise occurs due to the separation flows. Also, if the spacings between adjacent curved vanes are uniformized so that the flow regulation is optimized on the front side in the rotational direction of the turbo fan, the flow regulation effect on the curved vanes on the rear side becomes smaller.
- An object of the present invention is therefore to provide an indoor unit for an air conditioner capable of efficiently regulating the blown-off air and reducing noise.
- the present invention provides an indoor unit for an air conditioner in which a turbo fan disposed within a casing sucks air from a front side of the indoor unit and blows out the air radially outwardly relative to an axis of the turbo fan, comprising: a planar vane mounted to an air outlet provided in the casing; and a plurality of curved vanes arrayed on the planar vane in a longitude direction of the planar vane at the air outlet and curved so as to guide the air blown out from the turbo fan to an outward direction generally vertical to a longitudinal direction of the planar vane, where the plurality of curved vanes have curvatures increasing from a rear side of the planar vane relative to a rotational direction of the turbo fan toward a front side of the planar vane.
- the air sucked from the front side of the indoor unit by the turbo fan is blown out outward in the rotational direction at an angle of about 40 degrees to a tangent to the outer circumference of the turbo fan.
- the air flow is regulated along the planar vane and the plurality of curved vanes mounted to the air outlets of the casing.
- the angle of the air flow to the longitudinal direction of the air outlets becomes larger on the rear side of the air outlets in the rotational direction of the turbo fan, while the angle of the air flow to the longitudinal direction of the air outlets becomes smaller on the front side of the air outlets in the rotational direction of the turbo fan.
- the incident angle of the air flow on all the curved vanes is decreased so that the air flow regulated by the planar vane and the plurality of curved vanes is blown out in a desired direction (e.g., along the plane perpendicular to the longitudinal direction of the air outlets) without causing any separation of air flow to the curved vanes. Consequently, the blowoff air from the turbo fan can be efficiently regulated, and besides noise can be reduced.
- a region where the plurality of curved vanes are arrayed is divided into a plurality of sub-regions, and the curvatures of the curved vanes are different among the plurality of sub-regions.
- the design can be simplified as compared to when the configuration of the curved surfaces of all the curved vanes is designed optimally depending on variations in the angle of air flow to the longitudinal direction of the air outlets, and besides efficient flow regulation and noise reduction can be achieved with a simple construction, thus allowing a cost reduction.
- spacings between adjacent curved vanes become smaller from the rear side of the planar vane relative to the rotational direction of the turbo fan toward the front side of the planar vane.
- the indoor unit for an air conditioner of this embodiment by forming the plurality of curved vanes so that spacings between adjacent curved vanes become smaller from rear side toward front side in the rotational direction of the turbo fan, the flow regulation effect on the curved vanes on the rear side of the rotational direction of the turbo fan is decreased according to the variations in the angle of the air flow to the longitudinal direction of the air outlets, while the flow regulation effect on the curved vanes on the front side of the air outlets in the rotational direction of the turbo fan is increased.
- the blowoff air from the turbo fan can be regulated further efficiently without unnecessarily increasing the flow regulation effect, and besides noise can be reduced.
- a region where the plurality of curved vanes are arrayed is divided into a plurality of sub-regions, and the curvatures of the curved vanes are different among the plurality of sub-regions while the spacings between adjacent curved vanes are different among the plurality of sub-regions.

- the planar vane and the plurality of curved vanes are integrally formed.
- the planar vane serves also as a support member for supporting the plurality of curved vanes.
- the number of parts is decreased and therefore the air outlet structure can be simplified, thus allowing a cost reduction.
- an incident angle of the air flow is generally equal along an entire upstream-side leading edge of each curved vane on the planar vane.
- the incident angle of the air flow is generally equal along the entire upstream-side leading edge each curved vane on the planar vane.
- the air flow is less subject to disturbance, so that noise can be further reduced.

- the flow regulation effect on the curved vanes on the rear side of the rotational direction of the turbo fan is decreased, while the flow regulation effect on the curved vanes on the front side of the air outlets in the rotational direction of the turbo fan is increased.
- the air flow is regulated securely on one side on which the curved vanes have smaller angles of air flow to the longitudinal direction of the air outlets without unnecessarily increasing the flow regulation effect on the rear side in the rotational direction of the turbo fan, so that the regulated air is blown out from the air outlets in a desired direction (e.g., along the plane perpendicular to the longitudinal direction of the air outlets).
