Abstract
Description
- A blower in which a fan is detachable, a groove is formed in a fan boss, and the groove and a roll pin are engaged with each other to serve as a fan rotation stopper is known (for example, refer to PTL 1).
- The blower will be described below with reference to
FIG. 5 that is a perspective view showing a configuration of a conventional blower. As shown inFIG. 5 ,fan 101 includesboss portion 102 at the center thereof, and includes a plurality ofblades 103 on the circumference thereof. At a center of axis ofboss portion 102,shaft hole 105 in which shaft 104 (only the shaft is shown) of a motor is inserted andengagement groove 107 are formed, so thatfan 101 is in a rotation stopping state. Aftershaft 104 is inserted intoshaft hole 105,spinner 108 is rotated and fixed to a distal end side of boss portion 102 (fixing mechanism is not shown), andfan 101 is set in a retaining state.Engagement groove 107 mentioned here is a groove in a direction orthogonal toshaft hole 105, and is engaged withroll pin 106 mounted onshaft 104. - In the conventional blower as described above, roll
pin 106 andengagement groove 107 collide with each other when a torque of the motor is changed or when the motor is activated to generate noise. As the countermeasure against the noise, a gap betweenroll pin 106 andengagement groove 107 may be reduced to prevent the collision. However,fan 101 is not easily mounted onshaft 104, andshaft 104 is disadvantageously imperfectly mounted onfan 101. - PTL 1: Unexamined Japanese Patent Publication No. 62-10532
- A blower according to the present invention includes a motor, a fan driven by the motor, a casing that covers a circumference of the fan, a control circuit that drives and controls the motor, a cylindrical roll pin mounted on a shaft of the motor at right angle to an axis line of the shaft, and a boss portion inserted into the shaft, wherein an end face of the boss portion at one side inserted to the shaft is provided with a groove having an opening and a bottom part to engaged with the roll pin, side walls of the groove are slanted to widen from the bottom part to the opening, the side walls have straight portions formed to confront each other in parallel to a longitudinal direction of the shaft and extending toward the opening from a start point corresponding to a central axis of the roll pin, and a distance between the confronting straight portions is equal to a diameter of the roll pin.
- With this configuration, since a width of an inlet port of the groove is larger than that of the roll pin when the roll pin is inserted into the groove, the roll pin can be easily inserted into the groove. When the roll pin is fixed to a position where the fan is rotated, since the width of the groove is equal to or smaller than the diameter of the roll pin, collision noise between the groove and the roll pin is prevented from being generated.

-
FIG. 1 is an exploded perspective view of a ceiling-embedded ventilation fan including a blower according to an embodiment of the present invention, andFIG. 2 is a diagram showing an interior of the ceiling-embedded ventilation fan including the blower. The ceiling-embedded ventilation fan shown inFIGS. 1 and 2 is fitted in a roof space (not shown) of a room by being embedded in the roof space. The ceiling-embedded ventilation fan includessuction opening 1,frame 3,motor 4,fan 5,casing 6, dressedpanel 7,control circuit 8, andcircuit case 9. -
Suction opening 1 mentioned here is arranged on a lower surface of the ceiling-embedded ventilation fan and corresponds to an opening of a ceiling board.Frame 3 configures a side surface of the ceiling-embedded ventilation fan and hasdischarge opening 2.Motor 4 is fixed to a top surface offrame 3.Fan 5 is driven bymotor 4.Casing 6 covers the circumference offan 5. Dressedpanel 7 is detachably mounted to cover the opening in the lower surface offrame 3 from the room side.Control circuit 8 is mounted on the top surface offrame 3 to drive and controlmotor 4.Circuit case 9stores control circuit 8 therein. Blower 23 mentioned here includesmotor 4,fan 5,casing 6,control circuit 8, andcircuit case 9. -
FIG. 3 is a detail view of a portion A inFIG. 2 , andFIG. 4 is a detail view of a portion B inFIG. 2 . As shown inFIG. 3 ,blower 23 according to the embodiment of the present invention includesroll pin 13,groove 14, andboss portion 15. As shown inFIG. 4 ,blower 23 includes detachingdevice 22 including one pair of integrated holding units 11 and one pair of integrated pressing units 12. - As shown in
FIG. 3 ,roll pin 13 has a cylindrical shape, and is mounted onshaft 10 ofmotor 4 at right angle toaxis line 10 a ofshaft 10.Boss portion 15 is arranged at the center offan 5 and inserted intoshaft 10. Groove 14 to engageroll pin 13 with motor-side end face 15 a that is an end face ofshaft 10 on an insertion side is formed inboss portion 15.Groove 14 includes opening 18 andbottom portion 17. - As shown in
FIG. 4 , pressing units 12 are pressed to move holding portions 11. Shaft 10 is held by one pair of holding units 11. When pressing units 12 perform a nipping operation, a holding force of holding units 11 is released to make it possible to makefan 5 andshaft 10 detachable. A sensor-less DC motor is used asmotor 4, andcontrol circuit 8 is a drive circuit of the DC motor. - Since the sensor-less DC motor does not have a hall element in
motor 4, a rotor position ofmotor 4 is fixed by a DC excitation mode in activation. Thereafter, the sensor-less DC motor outputs an energization signal of forced commutation and rotates. When the sensor-less DC motor rotates, induced voltages are generated from coils in phases (U phase, V phase, and W phase). When a signal showing the positive/negative of each phase terminal voltage including an induced voltage is input as a position signal, the energization signal of forced commutation is automatically switched to an energization signal based on a position signal input (induced voltage). For this reason, the sensor-less DC motor is driven by sensor-less driving. In the DC excitation mode, sinceshaft 10 rotates to the left and the right, collision repeatedly occurs betweenroll pin 13 and groove 14 to generate collision noise. - Since the sensor-less DC motor does not have a uniform rotating force and repeatedly generates uneven torque due to a cogging phenomenon, rotational movements of
roll pin 13 andgroove 14 do not coincide with each other. For this reason, collision repeatedly occurs betweenroll pin 13 and groove 14 to generate collision noise. - In contrast to this, as shown in
FIG. 3 ,side wall 16 ofgroove 14 is slanted to widen frombottom portion 17 ofgroove 14 to opening 18. In a part ofside wall 16,side wall 16 hasstraight portions 19 formed to confront each other in parallel to a longitudinal direction ofshaft 10 and extending toward opening 18 from a start point corresponding tocentral axis 13 a ofroll pin 13. More specifically, inFIG. 3 , a part except forstraight portions 19 ofside wall 16 has a gradient extending in an upper left direction and having a small inclination.Distance 19 a between the confronting straight portions is equal todiameter 13 b of the roll pin. - As a result, when
roll pin 13 is inserted intogroove 14, since a width of an inlet port ofgroove 14 is larger thanroll pin 13,fan 5 is easily inserted intoshaft 10. Whenroll pin 13 is mounted at a fixing position, i.e., a position wherefan 5 rotates, the width ofgroove 14 is equal to or smaller thandiameter 13 b of the roll pin. For this reason, a gap is eliminated betweenroll pin 13 andgroove 14, and collision noise is not generated. - Furthermore, as shown in
FIG. 4 , concave slot 20 with which holding units 11 are engaged is formed inshaft 10. A curved surface ofshaft 10 in which concave slot 20 is formed is chamfered C-shaped surface 21. Diameter 21 a in a longitudinal direction of the shaft of the C-shaped surface is set to be equal tolength 19 b of the straight portion shown inFIG. 3 . As a result, whenshaft 10 shown inFIG. 3 is inserted intofan 5, by a slipping force of holding units 11 along C-shaped surface 21 shown inFIG. 4 ,roll pin 13 is mounted at a position ofstraight portions 19. - As described above, in the blower according to the embodiment of the present invention, collision noise between
roll pin 13 andgroove 14 can be prevented from being generated, andfan 5 is easily fitted onshaft 10. - The present invention can be widely applied to a blower including a fan fitting device in which a roll pin is formed on a shaft of a motor used in a ventilation fan or the like, a groove engaged with the roll pin is formed as a fan rotation stopper in a boss portion of a fan.
