The present invention provides a bottom cover 100.
Referring to fig. 1, fig. 1 is a schematic cross-sectional view of a food processor 500 according to the present invention, wherein the food processor 500 includes a base assembly 300, the base assembly 300 includes a housing 310 and a motor 330 disposed in the housing 310, and a fan 350 is connected to a lower end of an output shaft of the motor 330. The base assembly 300 further includes a bottom cover 100 fastened to the lower end of the housing 310, and when the bottom cover 100 is mounted to the food processor 500, the fan 350 partially extends into the bottom cover 100. In the operation process of the food processor 500, the motor 330 rotates to drive the stirring blade of the food processor 500 to rotate, and simultaneously drives the fan 350 to rotate, so as to suck the outside air into the base assembly 300 and exchange heat with the heat generating components in the base, the fan 350 further drives the hot air to be discharged from the bottom cover 100, and due to the high-speed rotation of the fan 350, a large noise is generated in the process. Therefore, the bottom cover 100 is structurally modified to reduce the noise emitted from the food processor 500 to the outside.
Referring to fig. 2 and 3, fig. 2 and 3 are schematic perspective views of the bottom cover 100 of the present invention from two different viewing angles. In the embodiment of the present invention, the bottom cover 100 includes: the silencer comprises a base plate 110, a silencing cover 130 and a connecting cylinder 150, wherein the base plate 110 is provided with an air inlet 111 and an air outlet 113, one end of the silencing cover 130 is connected with the base plate 110, the air outlet 113 is positioned on the inner side of the silencing cover 130, the air inlet 111 is positioned on the outer side of the silencing cover 130, the connecting cylinder 150 is connected with one end, far away from the base plate 110, of the silencing cover 130, and the diameter of an inner cavity of the connecting cylinder 150 is smaller than that of the inner cavity of the silencing cover 130.
The bottom cover 100 is made of plastic, and the chassis 110, the muffling cover 130 and the connecting cylinder 150 are integrated. The air inlet 111 of the chassis 110 is disposed near the outer edge of the chassis 110, and the side wall of the muffling enclosure 130 is spaced between the air inlet 111 and the air outlet 113. Wherein the air inlets 111 are arranged in an arc shape and are oppositely arranged, and each air inlet 111 is arranged in a small arc shape for a grid hole shape. And the air outlet 113 is configured in a circular hole shape. During the operation of the food processor 500, the external air enters the base assembly 300 through the air inlet 111, and the air is discharged out of the base assembly 300 through the connecting tube 150, the muffling cover 130 and the air outlet 113 after heat exchange.
According to the technical scheme, the connecting cylinder 150 and the silencing cover 130 are arranged on the bottom cover 100, the diameter of the inner cavity of the silencing cover 130 is larger than that of the inner cavity of the connecting cylinder 150, when the bottom cover 100 is applied to the food processor 500, the heat dissipation fan 350 of the food processor 500 extends into the connecting cylinder 150, noise generated in the high-speed operation process of the fan 350 is transmitted to the inner cavity of the silencing cover 130 along the inner cavity of the connecting cylinder 150, and due to the fact that the diameter of the inner cavity of the silencing cover 130 is larger than that of the inner cavity of the connecting cylinder 150, energy is lost due to cavity expansion in the transmission process of the noise, the noise transmitted to the outside by the food processor 500 is reduced, and adverse effects of overlarge noise on a user are avoided.
Specifically, referring to fig. 5, the muffling cover 130 includes a cover body 133 connected to the chassis 110, a connecting ring 131 is disposed at an end of the cover body 133 away from the chassis 110 and protrudes inward, a connecting cylinder 150 is connected to a periphery of the connecting ring 131, a diameter of an inner cavity of the connecting cylinder 150 is smaller than a diameter of the inner cavity of the cover body 133, and the diameter of the inner cavity of the cover body 133 increases from an end close to the connecting ring 131 to an end away from the connecting ring 131.
The cavity diameter of the connecting cylinder 150 smaller than the cavity diameter of the noise-damping cap 130 in this embodiment may be defined as the cavity diameter of the connecting cylinder 150 smaller than the cavity diameter of the cap body 133. Further, the diameter of the inner cavity of the cover 133 is increased, the inner cavity of the cover 133 may be uniformly increased or increased in a jumping manner, and the inner cavity of the cover 133 is preferably uniformly increased. As can be seen from the foregoing, the noise generated in the housing assembly 300 is suddenly dissipated due to the cavity formed between the connecting cylinder 150 and the noise-reduction cover 130 during the transmission process, and the noise is dissipated again during the transmission process by making the cover 133 of the noise-reduction cover 130 to have a tendency to further expand, thereby further reducing the noise transmitted to the outside of the food processor 500.
Referring to fig. 2 and 5 again, the present invention further includes a sound returning hole 135 formed in the connecting ring 131, wherein the sound returning hole 135 is located outside the connecting cylinder 150 and is communicated with the inner cavity of the cover 133. By the arrangement of the sound returning hole 135, the noise in the cover 133 can be partially transmitted through the sound returning hole 135 to the inside of the housing assembly 300, and interfere with the noise in the housing assembly 300, so that the energy of the noise can be further consumed.
In order to further improve the noise reduction effect, referring to fig. 4, in an embodiment, the inner edge of the connection ring 131 forms a throat 137, the throat 137 communicates with the inner cavity of the connection barrel 150 and the inner cavity of the cover 133, and the diameter of the throat 137 is smaller than that of the inner cavity of the connection barrel 150.
The connecting cylinder 150 is connected to the middle portion of the connecting ring 131, i.e. the connecting ring 131 extends radially inward relative to the connecting cylinder 150 to form the necking 137. Through the setting of throat 137 for the noise experiences the process that the bore from the inner cavity of connecting cylinder 150 to throat 137 becomes small suddenly and the bore from throat 137 to the inner cavity of cover 133 becomes large suddenly in the process of being propagated from connecting cylinder 150 to air outlet 113, through such setting, the energy loss effect of noise is more obvious and the noise reduction effect is better.
Furthermore, in this scheme, a plurality of air outlets 113 are arranged at intervals, the air outlets 113 are arranged at intervals in a ring shape, and the air outlets 113 can be located outside the projection of the necking 137 on the chassis 110. With such an arrangement, the noise directly transmitted to the chassis 110 through the necking 137 will be blocked by the chassis 110, the transmission path must be changed to guide to the air outlet 113, and the plurality of air outlets 113 are annularly spaced, the noise is divided again on the transmission path, in the process, the energy of the noise will be further consumed, and the noise transmitted to the outside of the food processor 500 will be further reduced. It can be understood that, when the necking 137 is not provided, the projection of the inner cavity of the connecting cylinder 150 on the chassis 110 is located inside the ring formed by the plurality of air outlets 113.
Further, in order to ensure the effect of noise transmission, which is weakened by the sudden change of the size of the inner cavity, the diameter of the inner cavity of the cover 133 is D1, and the diameter of the inner cavity of the connecting cylinder 150 is D2, wherein the ratio of D1 to D2 is greater than or equal to 1.2. By setting the diameter of the internal cavity of the cover 133 to the diameter of the internal cavity of the connecting cylinder 150 to the above ratio, the best effect of energy consumption during the transmission of noise can be ensured.
The height H of the cover 133 of the present invention is greater than or equal to 8 mm. Through the arrangement, the sound waves of the noise are reflected for multiple times in the cover body 133 and interfere with each other, so that the noise energy loss is large, and the noise reduction effect is good.
To further enhance the noise reduction effect, in an embodiment, the inner wall of the cover 133 is provided with a noise reduction material layer (not shown). The noise reduction material layer may be made of foam or other materials fixed to the inner wall of the cover 133 by gluing.
Further, the central axis of the connecting cylinder 150 coincides with the central axis of the cover 133. With the arrangement, air flows more smoothly during operation of the fan 350, and thus generated wind noise is small.
Referring to fig. 6, in another embodiment of the present invention, in order to reduce noise, a first boss 170 is further connected to an outer wall of the connecting cylinder 150 near one end of the connecting ring 131, and a first resonance cavity 171 communicated with an inner cavity of the connecting cylinder 150 is formed in the first boss 170.
The first boss 170 may be integrated with the connecting cylinder 150, and a through hole may be opened in a sidewall of the connecting cylinder 150 to communicate the first resonant cavity 171 with an inner cavity of the connecting cylinder 150. The first projection 170 may be formed to surround the connecting cylinder 150 for one circle or may be formed as several broken parts. By the arrangement of the first boss 170, after the noise in the connecting cylinder 150 enters the first resonant cavity 171 through the through hole, when the frequency of the noise sound is consistent with the resonant frequency of the resonant cavity (i.e. forming the helmholtz resonant cavity principle), the purpose of noise elimination and noise reduction is achieved.
Further, a second boss 190 may be further connected to an outer wall of the cover 133, and a second resonance cavity 191 communicated with the inner cavity of the cover 133 is formed in the second boss 190. It is understood that the first boss 170 and the second boss 190 may be selectively disposed in one or both of them, and the second boss 190 is disposed in a similar manner to the first boss 170, and will not be described herein again. By forming the second resonance cavity 191, part of the noise in the cover 133 can enter and be reduced by resonance, so that the noise reduction effect of the bottom cover 100 is further improved.
The present invention further provides a housing assembly 300, which includes a housing 310, a motor 330 accommodated in the housing 310, and a bottom cover 100, wherein an output shaft of the motor 330 is connected with a fan 350, the bottom cover 100 covers a lower end of the housing 310, and the fan 350 extends into the connecting cylinder 150.
