It can be understood that the value of L1/L2 can be 0.5 or 0.8 or 1.3 or 1.5 or 1.7 or 2, as long as the value of L1/L2 is more than or equal to 0.5 and less than or equal to 2, and the noise reduction effect is more obvious when the value of L1/L2 is larger in the range.
It will be appreciated that the air inlet 8 may be provided on the housing 27, or may be configured to provide air inlet, and may avoid interference between the air inlet and the air outlet 9.
Embodiment two:
the difference between this embodiment and the first embodiment is that the flow curve is a variable-section curve, as shown in fig. 3 and 4, the variable-section curve 13 is a variable-section curve, which can attenuate acoustic reactance and attenuate acoustic intensity of noise, the acoustic intensity is one of noise energy parameters, thus being beneficial to noise reduction, and the variable-section curve is also beneficial to continuous reflection of noise in the curve, so as to strengthen mutual interference of noise, further being beneficial to noise attenuation, improving user experience, the radial section of the flow curve 13 changes from the first communication end 14 to the second communication end 15 from small to large and then from large to small once, the radial section size at the first communication end 14 is equal to and minimum with the radial section size at the second communication end 15, and the radial section of the flow curve 13 at the middle position of the first communication end 14 and the second communication end 15 is maximum, so that the radial section of the flow curve 13 gradually increases from minimum to maximum and gradually decreases from maximum to minimum, thus the radial section of the flow curve 13 is gradually increased from minimum, the radial section of the noise can be released in the first communication end 13 first and then passes through the second communication end 15, thereby being more beneficial to noise attenuation effect is more obvious.
The first communication end 14 is in smooth transition connection with the spiral case 12, the first communication end 14 is provided with an upward inclined guide surface 16, so that the section of the first communication end 14 is suddenly expanded, sound waves with certain frequencies generate sudden changes of acoustic impedance at the section, the purpose of noise elimination is achieved, the second communication end 15 is in smooth transition connection with the air outlet 9, the second communication end 15 is provided with a downward inclined guide surface 16, so that the section of the second communication end 15 is suddenly contracted, sound waves with certain frequencies generate sudden changes of acoustic impedance at the section, the purpose of noise elimination is achieved, the first communication end 14 is provided with an upward inclined guide surface 16, the second communication end 15 is provided with a downward inclined guide surface 16, the expansion and the contraction are beneficial to releasing, collecting and attenuating noise, and the energy sudden changes of noise can be reduced, and the purpose of noise reduction is achieved.
The exhaust curve 17 is arranged between the second communication end 15 and the air outlet 9, the radial section of the exhaust curve 17 is gradually increased and is in smooth transition connection with the flow curve 13, so that the exhaust curve 17 is connected between the flow curve and the air outlet 9, the air flow flowing out of the flow curve 13 can be subjected to noise reduction treatment again, the noise intensity is collected again and is released and attenuated, the energy mutation of the noise is reduced, the noise reduction purpose is achieved, and the continuous reflection of the noise in the exhaust curve is facilitated to strengthen the mutual interference of the noise due to the gradual increase of the radial section of the exhaust curve 17, so that the effect of noise attenuation can be achieved.
The higher the rotational speed of the motor 3, the more noise is generated, and the idle rotational speed of the motor 3 in this embodiment is 25000r/min, where the idle rotational speed refers to the rotational speed at which the motor idles. Because the circulation bend 13 is arranged between the volute 12 and the air outlet 9, the air flow of the heat dissipation air duct 10 is ensured to pass through the circulation bend 13 before flowing to the air outlet 9 through the volute 12, and the L1/L2=1, the circulation path of the air flow is increased, the noise carried by the air flow is greatly weakened, the no-load rotating speed of the motor 3 in the embodiment is 25000r/min, the effect of high-speed crushing of the food processor can be achieved, and further, the food can reach the wall breaking standard and is easy to be absorbed by a human body. The circulation bend 13 substantially increases the circulation path of the air flow, the circulation bend 13 is arc-shaped, the whistle noise is reduced, the radian beta of the circulation bend 13 is 135 degrees, the noise can be effectively weakened in the process of the circulation bend 13, the larger the radian of the circulation bend 13 is, the better the noise is in theory, the more the noise reduction is facilitated, but the noise is limited by the size of the engine base.
It can be understood that the radian β of the flow bend 13 may be 60 ° or 80 ° or 100 ° or 120 ° or 150 ° or 170 ° or 180 °, so long as the radian β is not smaller than 60 °, it is only necessary to ensure that noise is effectively attenuated in the process of propagating in the flow bend 13, and the larger the radian of the flow bend 13, the more obvious the noise reduction effect is, but the size is limited by the size of the engine base.
It can be understood that the radial cross section of the flow bend 13 is changed from the first communication end to the second communication end from small to large at least once, so that the molding is easy, the purpose of changing the cross section can be realized, and the noise reduction requirement is further met.
