[0047] In conjunction with Figures 1 to 7 As shown, in conjunction with the specific embodiments of the present application, a kind of cooking machine is provided.

[0048] Specifically, the cooking machine includes: machine body 10 and base assembly 20, base assembly 20 includes bottom shell 22 and mounting seat 21, bottom shell 22 is connected with machine body 10, mounting seat 21 is detachably connected with bottom shell 22, at least one of mounting seat 21 and bottom shell 22 is provided with air duct structure 23, air duct structure 23 has sound attenuation air duct 25, the length direction of sound attenuation air duct 25 extends along the circumferential direction of machine body 10 and is arranged.

[0049] In combination Figures 2 to 3 As shown in one embodiment of the present application, inside the bottom shell 22, a wind channel structure 23 is arranged in the mounting seat 21, and the length direction of the sound-attenuating wind channel 25 is arranged along the circumference of the machine body 10 to change the flow state of the airflow and achieve the effect of reducing noise.

[0050] In combination Figure 4 And Figure 5 As shown in another embodiment of the present application, a wind channel structure 23 is designed, which includes a sound-attenuating wind channel 25 arranged in a spiral along the circumference of the machine body 10 to form a complex airflow passage.

[0052] Through the above embodiments, compared with the machine model without the noise-reducing wind channel design, the noise of the food processor during operation is reduced, the user's experience in the early morning or at night is improved, and the noise interference to family members or neighbors is reduced. At the same time, since the design of the wind channel structure 23 does not sacrifice the heat dissipation performance, the temperature control of the motor is still stable during long-time operation of the food processor, ensuring the long-term reliability and safety of the equipment. The present scheme realizes effective noise control at a low cost, while maintaining the heat dissipation and cleaning convenience of the equipment, and is a design that takes into account noise, heat dissipation and maintenance.

[0053] The technical scheme of the present application is applied, by arranging a wind channel structure 23 in at least one of the mounting seat 21 and the bottom shell 22 of the base assembly 20 of the food processor, forming a sound-attenuating wind channel 25, the length of which extends along the circumference of the machine body, effectively guiding and lengthening the airflow path, and significantly reducing the noise level during operation of the motor and stirring of food materials by utilizing the natural attenuation characteristics of the airflow, creating a more peaceful use environment. At the same time, the detachable design of the wind channel structure 23 facilitates maintenance and cleaning, ensuring the long-term stable operation of the equipment, without sacrificing the heat dissipation performance, realizing the optimized balance between noise reduction and heat dissipation, greatly improving the user's life quality and product experience, and solving the problem of loud noise during use of the food processor in the prior art.

[0054] Further, the air duct structure 23 comprises a plurality of air duct side plates, which are arranged outwardly and spaced apart along the radial direction of the mounting base 21, and the partial sound attenuation air duct 25 is formed between adjacent air duct side plates.

[0055] In combination Figure 2 and Figure 3 As shown in FIG. 1, the air duct structure 23 comprises a plurality of air duct side plates, which are arranged outwardly and spaced apart along the radial direction of the mounting base 21, and the partial sound attenuation air duct 25 is naturally formed between adjacent air duct side plates through ingenious layout. This design utilizes the space between the side plates as an airflow passage, further increases the complex path of airflow, and promotes the adjustment of the direction and speed of airflow multiple times when passing through these narrow and changing passages, thereby enhancing the noise attenuation effect. In addition, the spaced air duct side plates can also disperse the heat generated during the operation of the motor, and through multiple directions of heat dissipation, the heat dissipation efficiency is improved, ensuring the stable operation of the motor.

[0056] Further, the air duct structure 23 comprises a first air duct side plate 231 and a second air duct side plate 232, the first air duct side plate 231 is connected with the bottom plate of the mounting base 21, the first air duct side plate 231 and the bottom plate of the mounting base 21 enclose a first mounting space 2312, both ends of the first air duct side plate 231 are spaced apart to form an overflow passage 2311, and the first mounting space 2312 is used for accommodating part of the bottom shell 22; the second air duct side plate 232 is arranged outside the first air duct side plate 231, and the second air duct side plate 232 and the first air duct side plate 231 form part of the sound attenuation air duct 25, both ends of the second air duct side plate 232 are spaced apart to form a first outlet 2321 of the sound attenuation air duct 25; wherein the airflow in the first mounting space 2312 is discharged through the overflow passage 2311 to the sound attenuation air duct 25 formed between the first air duct side plate 231 and the second air duct side plate 232, and then discharged out of the mounting base 21 through the first outlet 2321.

[0057] In combination Figure 2 and Figure 3 As shown in FIG. 1, through the cooperation of the first air duct side plate 231 and the second air duct side plate 232, the precise guidance of the airflow inside the food processor and the multi-stage attenuation of the noise are realized. This structural design makes the airflow pass through the sound attenuation air duct 25 multiple times for disturbance and attenuation, significantly reducing the noise level. Finally, the airflow processed by the sound attenuation air duct 25 between the first air duct side plate 231 and the second air duct side plate 232 is smoothly discharged out of the mounting base 21 through the first outlet 2321, which not only ensures the heat dissipation efficiency, but also effectively controls the noise.

[0058] Further, in combination Figure 3As shown, the airflow passage 2311 is arranged in a staggered manner with the first outlet 2321. Such arrangement can achieve irregular airflow inside the sound-damping air duct 25, so that the noise is further reduced after multiple reflections and absorption. In addition, the uniform distribution of airflow and the extension of the heat dissipation path help the motor and internal components to maintain stable temperature during high-load operation, prevent overheating, prolong the service life of the equipment, and also improve the safety of user use. Finally, the staggered design also increases the assembly flexibility between the mounting seat 21 and the bottom shell 22, facilitating manufacturing and maintenance, reducing production cost and user maintenance difficulty.

[0059] Further, the bottom shell 22 includes a bottom shell body 220 and a first heat dissipation part 223, the bottom shell body 220 is connected with the body 10, and the bottom shell body 220 surrounds an exhaust passage 221, the exhaust passage 221 is in communication with the first outlet 2321 of the sound-damping air duct 25, and a plurality of air outlets 2201 are arranged on the side wall of the exhaust passage 221; the first heat dissipation part 223 is located in the bottom shell body 220, and the first heat dissipation part 223 is arranged in cooperation with the first mounting space 2312, and the first heat dissipation part 223 is provided with a first heat dissipation opening, which is in communication with the inside of the body 10; wherein the plurality of air outlets 2201 are arranged in a circumferential direction of the first heat dissipation part 223, and the airflow in the first mounting space 2312 is discharged out of the mounting seat 21 through the first outlet 2321, and then discharged out of the bottom shell 22 through the plurality of air outlets 2201.

[0060] In combination Figure 2 As shown, the first heat dissipation part 223 is located in the bottom shell body 220, which is arranged in cooperation with the first mounting space 2312, and is internally designed with a first heat dissipation opening, which is in direct communication with the inside of the body 10, so that the heat generated by the motor operation can be quickly conducted to the first heat dissipation part 223, and then discharged through the exhaust passage 221 and the air outlet 2201. By arranging the air outlets 2201 in a circumferential direction of the first heat dissipation part 223, the airflow is realized in multiple directions and the heat is discharged in multiple points, which not only improves the heat dissipation efficiency, but also reduces the noise through the complex path of airflow.

[0061] Further, the air duct structure 23 comprises a third air duct side plate 233, and the mounting seat 21 comprises a mounting ring 211 connected with the bottom plate of the mounting seat 21, the mounting ring 211 surrounds to form a second mounting space 2111 for accommodating part of the bottom shell 22; wherein the third air duct side plate 233 is connected with the bottom plate of the mounting seat 21, one end of the third air duct side plate 233 is arranged close to the mounting ring 211, the other end of the third air duct side plate 233 extends outward along the circumferential direction of the mounting ring 211 and towards the radial direction of the mounting seat 21, the third air duct side plate 233 and the mounting ring 211 form part of the sound attenuation air duct 25, and the adjacent third air duct side plates 233 form another part of the sound attenuation air duct 25, and the side wall of the mounting seat 21 is provided with a second outlet 251 communicating with the sound attenuation air duct 25; wherein the airflow in the second mounting space 2111 is discharged out of the mounting seat 21 through the sound attenuation air duct 25 and the second outlet 251.

[0062] In combination Figure 4 and Figure 5 As shown in the drawings, in this embodiment, a complex sound attenuation air duct system is formed by the cooperation between the spiral extension of the third air duct side plate 233 and the mounting ring 211, so that the airflow can experience more disturbance and attenuation before being discharged. The spiral third air duct side plate 233 increases the contact area of the airflow with the surface of the bottom shell 22 and the mounting seat 21, which helps to quickly dissipate heat. At the same time, through the optimization design of the second outlet 251, the smooth discharge of the airflow is realized, avoiding local airflow blockage, improving the uniformity and efficiency of heat dissipation, ensuring the stable operation of the internal components of the equipment and prolonging the service life of the equipment.

Especially under high power operation, the baffle 212 can help to disperse heat and avoid local overheating, ensuring the stability of the motor and internal components, and prolonging the service life of the equipment. In practical application, this design not only can significantly improve the quietness of the equipment, but also can ensure the stability and safety of the equipment under various working conditions.

[0065] Further, the bottom shell 22 comprises a bottom shell body 220 and a second heat dissipation part 224, the bottom shell body 220 is connected with the body 10, the bottom shell body 220 is provided with an air outlet 222, the air outlet 222 is arranged in communication with the second outlet 251; the second heat dissipation part 224 is connected with the bottom shell body 220, the second heat dissipation part 224 is arranged in cooperation with the second mounting space 2111, the second heat dissipation part 224 is provided with a second heat dissipation opening, the second heat dissipation opening is arranged in communication with the inside of the body 10; wherein the airflow in the second mounting space 2111 is discharged outside the mounting seat 21 through the second outlet 251 of the sound attenuation air duct 25, and then discharged outside the bottom shell 22 through the air outlet 222.

[0067] In combination Figure 6 and Figure 7 As shown in another embodiment of the present application, the air duct structure 23 comprises a fourth air duct side plate 234, the fourth air duct side plate 234 is connected with the bottom shell body 220, one end of the fourth air duct side plate 234 is arranged close to the second heat dissipation part 224, the other end of the fourth air duct side plate 234 extends outward in a spiral shape along the circumferential direction of the second heat dissipation part 224 and towards the radial direction of the bottom shell 22, the second end of the fourth air duct side plate 234 is arranged close to the air outlet 222, the fourth air duct side plate 234 and the second heat dissipation part 224 form part of the sound attenuation air duct 25, adjacent fourth air duct side plates 234 form another part of the sound attenuation air duct 25, the sound attenuation air duct 25 is arranged in communication with the air outlet 222; wherein the gas discharged by the second heat dissipation part 224 passes through the sound attenuation air duct 25 and then is discharged outside the bottom shell 22 through the air outlet 222.

[0068] In combination Figure 6As shown, the spiral design of the fourth air duct side plate 234 increases the path length and complexity of the airflow through the sound attenuation air duct 25, so that the airflow undergoes multiple disturbances and attenuations before being discharged, effectively reducing noise. The sound attenuation air duct 25 in this embodiment adopts a double-layer structure, i.e. the fourth air duct side plate 234 is arranged on the bottom shell body 220, which cooperates with the spiral turbulence structure formed by the third air duct side plate 233 arranged on the bottom plate of the mounting seat 21 to form a double-layer turbulence structure. This not only increases the travel distance of the airflow, so that the noise is attenuated in a longer path, but also the spiral fourth air duct side plate 234 can promote the uniform distribution of airflow in the bottom shell 22, effectively avoiding local overheating, ensuring that the motor and internal components can operate stably under various working conditions, and prolonging the service life of the equipment.

[0069] Further, the height of the mounting ring 211 is lower than the height of the third air duct side plate 233. In combination with Figure 7 As shown, the height difference design of the mounting ring 211 and the third air duct side plate 233 enables the airflow to experience a more gentle and complex path when being discharged from the second mounting space 2111 through the sound attenuation air duct 25 and the second outlet 251, increasing the contact area and time of the airflow with the air duct structure, which helps to further reduce noise.

[0070] From the above description, it can be seen that,

[0071] 1) Through the synergistic effect of the first air duct side plate 231 and the second air duct side plate 232, precise guidance of the airflow inside the food processor and multi-stage attenuation of noise are achieved. This structural design enables the airflow to undergo multiple disturbances and attenuations when passing through the sound attenuation air duct 25, significantly reducing the noise level.

[0072] 2) In this embodiment, a complex sound attenuation air duct system is formed by the cooperation between the spiral extension of the third air duct side plate 233 and the mounting ring 211, so that the airflow can undergo more disturbances and attenuations before being discharged. The spiral third air duct side plate 233 increases the contact area of the airflow with the surface of the bottom shell 22 and the mounting seat 21, which helps to quickly dissipate heat. At the same time, through the optimization design of the second outlet 251, the airflow is discharged smoothly, avoiding local airflow blockage, improving the uniformity and efficiency of heat dissipation, ensuring the stable operation of the internal components of the equipment and prolonging the service life of the equipment.

[0073] 3) By optimizing the bottom shell air duct design, a fourth air duct side plate 234 is set on the bottom shell body 220. This, together with the spiral turbulence structure formed by the third air duct side plate 233 set on the bottom plate of the mounting base 21, forms a double-layer turbulence structure. This not only increases the airflow travel distance, making noise attenuate in a longer path, but the spiral fourth air duct side plate 234 can also promote the uniform distribution of airflow in the bottom shell 22, effectively avoid local overheating, ensure that the motor and internal components can maintain stable operation under various working conditions, and extend the service life of the equipment.
