Description
The shaft end that the present invention relates to the output shaft (output shaft is protruding from shell) at motor installs the blower of impeller, be applicable to the shell of this blower, be applicable to the shell of motor of this blower and the vibration control equipment that is applicable to this blower.
On traditional horizontal fan for example shown in Figure 26, the motor 31 of drives impeller 30 is located at a side of fan housing 32, and opposite side is provided with the capacitor that is used to make motor 31 runnings, switches impedance to change the electricity pieces such as relay 33 of motor 31 speed.On this blower, shake fan housing to change the motor of wind direction, the motor 31 of such as shown in figure 27 reducing gear that is made of Worm gear mechanism 34 is housed in the employing, and with this motor 31 impeller 30 and fan housing 32.
But, on the blower of above-mentioned formation, the complex structure of motor 31 and costing an arm and a leg.Moreover, the maintenance of reducing gear etc. is also inconvenient.And, because electricity piece 33 is configured in the outside of fan housing 32, so the shortcoming that also exists single unit system to maximize.Afterwards, for example developed as shown in Figure 28, motor 31 and the motor 35 that shakes fan housing 32 of wheel rotor 30 separated design, and the modified model blower that the motor 31 of wheel rotor 30 and the motor 35 that shakes fan housing 32 laterally are arranged side by side.This blower is around the motor 31 of wheel rotor 30, and configuration comprises the electricity piece 33 of the motor 35 that shakes fan housing 32, can make the total length of blower shorter than form noted earlier.
Even on above-mentioned traditional modified model blower, also have several problems.Promptly, laterally be arranged side by side next door owing to shake the motor 35 of fan housing 32 and capacitor and these electricity pieces 33 of relay at the motor 31 of wheel rotor 30, so, the transverse dimension of blower is big, and, make and the wiring route complexity of electrical wiring, make the installation of electricity piece 33 also become complicated because installing space is narrow and small.
The employed outer cover of above-mentioned this blower adopts elongated shape more, by 2 blocks of side plates that constitute the outer cover two ends with directly be fixed on and form vertically elongated suction port between this side plate and 2 opposed guide plates of exhaust port constitute.Guide plate is crooked to the inside ribbon-shaped members, and makes the width of side's guide plate wideer than the width of the opposing party guide plate.Each end of each guide plate is fixed on each side plate.Because with each guide plate of fixing across the state both sides between the side plate is banded, so, very firm with fixing of side plate.In the past, the maximum method of fixedly employing between side plate and the guide plate is welding, for example can carry out like that shown in Figure 29,30.
That is, on the inner side surface of side plate 230, utilize pressure processing to cut 3 projection tab 232 and 2 projection tab 234 that support another guide plate 233 ora terminalis that support guide plate 231 ora terminalis in a circumferential direction side by side.The inner side surface of guide plate 231 ora terminalis props up on 3 projection tab 232, reaches under the state that the inner side surface with guide plate 231 joins at end face to be fixed on each projection tab 232 with spot welding.Another guide plate 233 joins the inner side surface of its ora terminalis and 2 projection tab 234 too, reaches under the state that the inner side surface with side plate 230 joins at end face to be fixed on each projection tab 234 with spot welding.
On the outer cover of above-mentioned traditional drum blower fan, the internal surface of guide plate 231,233 is crooked, relative therewith, the surface of projection tab 232,234 all is the plane, maintain side plate 230 and guide plate 231,233 when therefore being difficult in welding, so, easily between the end face of guide plate 231,233 and side plate 230, stay some spaces, thereby make the form of the composition of shaking outer cover in order to change wind direction, have such problem: vibration makes the end face of guide plate 231,233 contact with side plate 230, is easy to generate the abnormal sound of what is called " dither noise ".And, keep coupled condition owing to making between guide plate 231,233 and the side plate 230 with spot welding, thus the assembling trouble, and can only after assembling, spray paint.
