Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a food processing machine with optimized structure. Background Art

[0002] In existing food processing machines where the motor is built into the main machine, a duct structure is generally provided under the motor cover to achieve heat dissipation and exhaust of the motor. The duct structure is directly in contact with the base of the main machine to form an outlet duct to discharge the hot air flow after the heat dissipation of the motor.

[0003] In the solutions of the prior art, the first solution is that the air duct structure and the base are separate structures and the two are fixedly connected. On the one hand, when the machine is working, the vibration generated by the motor is easily transmitted to the base through the air duct structure, which increases the probability of resonance of the structural parts and is not conducive to reducing the working noise of the machine; on the other hand, since the air duct structure needs to cooperate with the base, the two are prone to assembly errors, resulting in instability of the formed air outlet duct, and when replacing a host of different models or sizes, it is necessary to match different bases to produce a new air duct structure, resulting in increased costs. Otherwise, the same air duct structure is difficult to adapt to different bases, which will inevitably affect the formation of the air duct and make it difficult to ensure that the motor can achieve effective heat dissipation. The second solution is that the air duct structure and the base are an integrated structure. This solution requires the motor cover to be installed in conjunction with the air duct structure. This solution also has the problem that the vibration generated by the motor is easily transmitted to the base, and the same motor cover is difficult to adapt to hosts of different models or sizes, resulting in poor versatility of the motor assembly composed of the motor and the motor cover.

[0004] In addition, the motor assembly in the above-mentioned prior art solution cannot form a complete air inlet-outlet heat dissipation structure, and the performance of the motor assembly needs to be improved, which is not conducive to the motor assembly adapting to host computers of different models or sizes, reducing the versatility of the motor assembly and increasing the development cost of products under multiple models.

[0043] like Figures 1 to 5As shown, the present application provides a food processing machine with optimized structure, including a main machine 10, wherein the main machine 10 includes a main body 101 and a base 102 forming an installation cavity, wherein a motor assembly 11 is arranged in the installation cavity, wherein the motor assembly 11 is flexibly installed below the main body 101, wherein the motor assembly 11 includes a motor 12, a motor cover 13 arranged on the outside of the motor 12, a duct cover 14 connected below the motor cover 13, and an duct cover 15, wherein an opening is arranged at the bottom of the duct cover 14, wherein the duct cover 15 is fixed to the duct cover 14 and closes the opening, wherein a heat dissipation duct 181 extending longitudinally is formed in the motor cover 13, wherein the duct cover 14 and the duct cover 15 enclose an air outlet duct 182 extending transversely and communicating with the heat dissipation duct 181, and wherein the motor assembly 11 is provided with an air inlet 16 communicating with the heat dissipation duct 181 and an air outlet 17 communicating with the air outlet duct 182.

[0044] In the food processing machine with optimized structure of the utility model, the motor assembly 11 itself can form a complete air inlet-outlet structure. The motor assembly 11 can achieve heat dissipation by relying on its own structure, thereby improving the reliability of heat dissipation. On this basis, the air duct cover 14 does not need to cooperate with the base 102 to form an air outlet duct, thereby preventing assembly errors of structural parts from affecting the formation of the air outlet duct and thus affecting the air outlet. Furthermore, the motor assembly 11 can be applied to host machines 10 of different models or sizes, thereby improving the versatility and enhancing the performance of the motor assembly 11.

[0045] like Figure 1 and Figure 2 As shown, the host 10 includes a main body 101 and a base 102, and the main body 101 and the base 102 are enclosed to form an installation cavity, and a motor assembly 11 is arranged in the installation cavity. The food processor also includes a cup body assembly. When the cup body assembly is placed in place on the main body 10, the crushing tool of the cup body assembly is coupled and connected with the motor 12, so that the crushing tool is driven by the motor 12 to rotate and cut the food. The motor assembly 11 is flexibly installed below the main body 101, and the motor assembly 11 can be hoisted on the main body 101, at which time the air duct cover 14 and the air duct cover 15 are suspended above the base 102; or the motor assembly 11 can be clamped between the main body 101 and the base 102, at which time the air duct cover 14 or the air duct cover 15 is in soft contact with the base 102 through the shock-absorbing pad 20. In the above-mentioned several methods, the vibration generated by the motor 12 can be prevented from being transmitted to the base 102, which is conducive to preventing the resonance of the structural parts and improving the noise reduction effect.

[0046] like Figure 3As shown, the motor assembly 11 includes a motor 12, a motor cover 13, an air duct cover 14 and an air duct cover 15 from top to bottom, forming a complete air inlet-air outlet structure (i.e., air inlet 16-heat dissipation duct 181-air outlet duct 182-air outlet 17). No matter which type of main body 101 and base 102 are adapted, the heat dissipation of the motor 12 is not affected, and there is no need to cooperate with the base 102 for installation, which improves the versatility of the motor assembly 11. The arrangement of the longitudinally extending heat dissipation duct 181 and the transversely extending air outlet duct 182 is conducive to the turning of the air flow direction. The air flow first flows along a vertical path in the heat dissipation duct 181, and then the air flow flows in the horizontal space in the air outlet duct 182 (for example, it can flow along an arc path or a spiral path). Finally, the air flow flows out from the air outlet 17 at the end of the air outlet duct 182. The overall flow path of the air flow is relatively long, which is conducive to reducing wind noise while dissipating heat, thereby improving the noise reduction effect.

[0047] As a preferred embodiment, the air outlet 17 is arranged on the air duct cover 14 or the air duct cover 15. Specifically, during the heat dissipation process of the motor 12, the hot air flow can be discharged from the side through the air duct cover 14, or can also be discharged through the air duct cover 15, that is, the air outlet 17 can be flexibly arranged to meet the heat dissipation requirements.

[0048] In one embodiment, the air duct cover 14 includes a volute 141 and an air guide portion 142 connected to one side of the volute 141 , and the end of the air guide portion 142 forms the air outlet 17 .

[0049] like Figure 3 As shown, a cooling fan 21 is provided at the lower end of the motor 12, and a volute 141 surrounds the outer side of the cooling fan 21. Under the action of the cooling fan 21, the airflow flows along the arc-shaped air duct in the volute 141 to the air guide portion 142 and then is discharged from the air outlet 17. The air guide portion 142 forms a chamber with an enlarged axial space relative to the volute 141, for example, so as to form a buffer chamber to reduce wind resistance, and the air outlet 17 has a certain opening size to improve the air outlet efficiency.

[0050] As a preferred implementation, the motor 12 includes a motor bracket 19 , the motor bracket 19 and the motor cover 13 surround the motor 12 inside, and the air inlet 16 is arranged on the top surface of the motor bracket 19 .

[0051] like Figure 3 As shown, the motor bracket 19 is disposed at the upper end of the motor 12, providing conditions for the installation of the motor 12 and the main body 101 and the motor 12 and the motor cover 13. Preferably, as Figure 2 and Figure 3As shown, the motor bracket 19 is provided with a mounting hole 191, the main body 101 is provided with a mounting column 103 extending downward, and the motor cover 13 is provided with a through hole 131 corresponding to the mounting hole 191. The fastener 104 can pass through the through hole 131 and the mounting hole 191 from bottom to top and be fixed in the mounting column 103, thereby realizing the installation of the motor assembly 11 and the main body 101, which can save installation steps. Furthermore, a shock absorber 105 is provided between the mounting hole 191 and the mounting column 103, which can realize the flexible installation of the motor assembly 11; the shock absorber 105 can also isolate the motor bracket 19 from the motor cover 13, thereby preventing the vibration generated by the motor 12 from being transmitted to the main body 101 and the motor cover 13, and improving the noise reduction effect.

[0052] During the heat dissipation process of the motor 12 , the cold airflow flows into the main unit 10 and can flow into the motor cover 13 through the top of the motor bracket 19 to cool the motor 12 , which is conducive to the cold airflow fully flowing through the motor 12 and thus improving the heat dissipation effect.

[0053] In one embodiment, the motor bracket 19 includes a mounting platform 192 that is installed in cooperation with the motor cover 13 and a boss 193 that protrudes upward along the mounting platform 192. The boss 193 is radially contracted relative to the mounting platform 192. A plurality of air inlet holes 194 are provided on the top surface of the boss 193. The airflow is guided from the air inlet holes 194 along the inner wall of the boss 193 to the motor 12.

[0054] like Figure 3 As shown, the boss 193 has a boss 193 top wall and a boss 193 side wall, and a plurality of air inlet holes 194 are arranged on the boss 193 top wall. Preferably, the projection of the motor 12 on the horizontal plane is located within the projection area of ​​the plurality of air inlet holes 194 on the horizontal plane, so as to achieve sufficient heat dissipation of the motor 12 and improve the heat dissipation efficiency. The side wall of the boss 193 can extend vertically or extend outwardly from top to bottom. When the side wall of the boss 193 extends outwardly from top to bottom, the airflow can be guided along the side wall of the boss 193 to increase the coverage in the radial direction, which can optimize the uniformity of the heat dissipation of the motor 12 and improve the heat dissipation effect.

[0055] As a preferred embodiment, a vent 132 is provided at the bottom of the motor cover 13, a mounting opening 143 is provided at the top of the air duct cover 14, a stop rib 133 extending downward is provided at the vent 132, and a matching rib 144 protruding upward is provided at the outer edge of the mounting opening 143, the stop rib 133 abuts against the inner side of the matching rib 144 and the vent 132 and the mounting opening 143 are connected.

[0056] like Figure 5As shown, the radial abutment of the stop rib 133 and the matching rib 144 can strengthen the sealing connection between the vent 132 and the mounting port 143, reduce air leakage, and ensure reliable heat dissipation. Preferably, a sealing ring is provided between the stop rib 133 and the matching rib 144 to strengthen the sealing connection and further prevent air leakage.

[0057] As a preferred embodiment, the lower end of the motor cover 13 is contracted so that the motor cover 13 forms an inclined side wall 134, and the inclined side wall 134 is provided with a screw column 135 extending downward, and the top of the air duct cover 14 is provided with a screw hole 145 for inserting the screw column 135.

[0058] like Figure 5 As shown, the contraction of the lower end of the motor cover 13 is conducive to gathering wind so that the airflow can quickly and fully flow into the air duct cover 14, improving the heat dissipation efficiency, and on the other hand, it provides conditions for the assembly of the motor cover 13 and the air duct cover 14. There is a certain distance between the inclined side wall 134 and the top of the air duct cover 14 to provide space for the screw column 135, which can avoid the screw column 135 protruding downward from the motor cover 13 when the bottom of the motor cover 13 is set to a horizontal state, and needs to be inserted into the air duct cover 14, resulting in complicated assembly.

[0059] As a preferred embodiment, the top of the air duct cover 15 is provided with an upwardly protruding spiral rib 151, and the air duct cover 14 is provided with a convex rib extending downward and docking with the spiral rib 151, and the convex rib cooperates with the spiral rib 151 to form a spiral air duct inside the air duct cover 14 and the air duct cover 15.

[0060] By setting a spiral air duct, the airflow flowing along the spiral air duct can extend the flow path, which is conducive to the gradual attenuation of noise energy to achieve the effect of noise reduction, so that the noise is reduced when the airflow is discharged from the air outlet 17, which can reduce the working noise of the machine and improve the user experience. Figure 3 As shown, preferably, the airflow flowing along the spiral air duct can form a detour angle greater than 360 degrees, so that the airflow flow path is extended, which is beneficial to reducing exhaust wind noise.

[0061] The present application does not specifically limit the relationship between the motor assembly 11 and the base 102, which can be set in any of the following ways.

[0062] In one embodiment, a gap is provided between the air duct cover 15 and the base 102, and the air duct cover 15 and the air duct cover 14 are suspended relative to the base 102. In this embodiment, the air duct cover 15 and the air duct cover 14 are not in contact with the base 102, which can prevent the vibration generated by the operation of the motor 12 from being directly transmitted to the base 102, reduce the probability of resonance of the structural parts, and improve the noise reduction effect.

[0063] In another embodiment, a shock-absorbing pad 20 is provided between the air duct cover 14 or the air duct cover 15 and the base 102. Specifically, the air duct cover 14 or the air duct cover 15 is in indirect contact with the base 102. By providing the shock-absorbing pad 20, the air duct structure and the base 102 can be in soft contact. The shock-absorbing pad 20 can absorb vibration and optimize noise reduction. Figure 2 As shown, an outwardly protruding mounting groove is provided at the edge of the air duct cover 14, and the shock-absorbing pad 20 is arranged in the mounting groove and the bottom of the shock-absorbing pad 20 contacts the base.

[0064] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.
