the scroll includes two straight line portions being approximately in parallel with each other on a whorl-like outer shape thereof, and a rotation shaft of the motor is positioned nearer to one of the two straight line portions, which is situated nearer a tongue portion of the scroll.
Fig. 1 is composed of a schematic plan view (a) and a schematic side elevation (b) illustrating an inner construction of an indoor unit of an air-conditioning apparatus provided with a sirocco fan in a first embodiment according to the present invention.
a reference numeral 10 denotes an indoor unit constituting an indoor air-conditioning apparatus, and is provided with a pair of sirocco fans 1 and 1, a fan motor 2 that rotationally drives these sirocco fans 1 and 1 simultaneously, and a heat exchanger 3 that performs a heat-exchanging operation with air that is blown out from the sirocco fan 1.

a refrigerating circuit for a refrigerant which is composed of a compressor, a condenser, an expansion valve, and an evaporator, all of which are not illustrated, and is configured to perform a cooling operation, a heating operation, or the like in a room.
the sirocco fan 1 is configured to have a fan-diameter ⁇ of 160 mm, a width dimension of 190 mm, the number of the blades of 40, and the heat exchanger 3 is provided with a heat transmission pipe of 12 steps, and an array pitch of the heat transmission pipe is 12.7 mm and a step pitch thereof is 20.4 mm, a length in an axial direction of the heat transmission pipe is 700 mm, and a draft resistance ⁇ P1 is 23.1 V 1.3 [Pa] (V: velocity[m/s]). Furthermore, the indoor unit 10 is configured to have a depth of 680 mm, a height of 210 mm, and a width of 960 mm.
the air in the room is sucked in from the suction opening 4 of the indoor unit 10, and is further sucked in from a suction opening of the scroll 6 in an axial direction.
the air to which a dynamic pressure and a static pressure are applied by a cylindrical blade array rotated in the scroll 6 by means of the fan motor 2, is blown out from a discharge opening that is opening into an air path of the indoor unit 10.
the air is heat-exchanged with the heat exchanger 3 installed in the air trunk, and is blown out from the blowing-out opening 5 into the room while being changed into cool air or warm air.
Fig. 2 is a view illustrating a positional relationship between a center of the rotation shaft of the fan motor and a center of a bell mouth 9 in the first embodiment of the present invention.
a point O denotes the center of the bell mouth 9 and a point P denotes the center of the rotation shaft of the fan motor 2 (a rotation center of the fan).
the scroll 6 of the present first embodiment is provided with two straight line portions 12 and 13 that are approximately in parallel with each other on a whorl-like outer shape of the scroll 6, and the center of the rotation shaft 7 of the fan motor 2 is offset toward the straight line portion 12 situated nearer the tongue portion 8 of the scroll 6. That is, the rotation center P of the fan is offset relatively to the center O of the bell mouth 9 and the offset position is set to be nearer the straight line portion 12 situated nearer the tongue portion 8.
Fig. 3 is a view illustrating a shape of the scroll in a second embodiment of the present invention.
the center of the bell mouth 9 conforms to the rotation center of the fan motor 2 (in a case that offsetting amount is zero).
the scroll 6 is provided with two straight line portions FH and EB that are approximately in parallel with each other on the whorl-like outer shape, and the shortest distance between the two straight line portions being approximately in parallel with each other is defined as CG, an intersecting point of a parallel line, which is in parallel with the straight line portions FH and EB of the scroll and passes through the center O of the bell mouth 9, and the outer shape of the scroll is defined as a point A, a point on the outer shape of the scroll, at which a distance between the outer shape of the scroll and the rotation center O of a fan is a maximum, is defined as a point B, intersecting points of a perpendicular line, which is perpendicular to the straight line portions FH and EB of the scroll and passes through the rotation center O of the fan, and the straight line portions FH and EB of the scroll are defined as a point C and a point G, respectively, a fan radius is defined as R, and an angle formed by a segment OA and a segment OB is defined as
the (OC-R)/R is set to satisfy the formula of (OC-R)/R ⁇ 0.45.
Fig. 4 is a perspective view showing a case that the fan body 11, the fan motor 2, and a motor-supporting stand 14 are assembled
Fig. 5 is a perspective view showing a case that an airflow duct 15 is not formed in the motor-supporting stand 14
Fig. 6 is a perspective view showing a case that the airflow duct 15 is formed in the motor-supporting stand 14.
Table 4 the noise value and the number of revolutions at the air-blowing amount of 16 m 3 /min of the air blown out from the indoor unit, in a case where the airflow duct is present in the motor-supporting stand and a case where the airflow duct is absent therein, are shown.
the constitution, in which the airflow duct 15 is provided in the motor-supporting stand 14 as described above, may be combined with the constitution of the above-described first embodiment or the second embodiment.
Fig. 7 is a schematic perspective view illustrating a case where a rib 16 is provided at each of both ends of the tongue portion 8 of the scroll in the present embodiment
Fig. 8 is a schematic side elevation thereof.
the rib 16 takes a form of an approximately rectangular parallelepiped shape, and the following formula is satisfied: segment XY ⁇ segment XZ, where a point in the rib 16 most apart from the fan body 11 is defined as a point X, a point in a circular arc portion of the tongue portion 8 most apart from the fan body 11 is defined as a point Y, and a point in the rib 16 nearest to the fan body 11 is defined as a point Z. Furthermore, in Fig.
a velocity component that is perpendicular to a blowing-out opening 18 in a case where the rib 16 is absent is shown.
a reverse flow area 20 indicated by a dashed line in the blowing-out opening 18 a flow toward an inner part of the fan from an outer part thereof is shown.
stream lines, which are formed at a time when smoke is infused from, for example, a segment 21 on the suction opening 17, are shown, so as to prove a reverse flow phenomenon.
the noise value and the number of revolutions can be reduced by providing a rib.
the reason is that in a case where the rib is absent and a resistive element to the flow such as a heat exchanger or the like is present, the higher the draft resistance of the resistive element becomes, the more the reverse flow phenomenon, in which the airflow is headed toward the inner part of the fan from the blowing-out opening 18, occurs at the blowing-out opening 18 of the sirocco fan 1 as illustrated in Fig. 9 , and this becomes a cause of increasing the noise value and the number of revolutions. That is, as illustrated in Fig.
an airflow blown out from gaps between the blades on a main plate side is headed toward both ends of the scroll along the scroll, and in the vicinity of both ends of the tongue portion 8, flows into a gap between the tongue portion 8 and the fan body 11, without flowing toward the blowing-out opening 18.
the airflow further flows into the gaps between the blades, and is blown out from the gaps between the blades on the main plate side, so that a flow 22 blown out toward the outer part of the scroll is caused.
the static pressure fluctuation on the wall surface is increased in the vicinity of both ends of the tongue portion, and a flow passing through the gaps between the blades many times is caused, and an air-blowing amount of the airflow that circulates in the inner part of the fan increases.
the rib 16 it is appropriate for the rib 16 to have a width in the range from 5 to 10 mm. Further, the constitution, in which the rib 16 of the present embodiment is provided, may be combined with any one of the constitutions of the above-described first to third embodiment.
