[0050] like Figures 1 to 13 As shown, the present application provides a miniaturized food processor, including a main unit 10 and a cup body assembly 11 installed on the main unit 10, wherein the main unit 10 is provided with a motor 13 and a power board 14, wherein the motor 13 is clamped from top to bottom by a motor bracket 16 and a motor lower cover 17, wherein the main unit 10 is further provided with a power board protective cover 15, wherein the power board protective cover 15 is arranged below the motor lower cover 17, and the power board 14 is installed on the power board protective cover 15 so that the power board 14 and the motor 13 are stacked axially.
[0051] Specifically, Figure 2 An exploded schematic diagram of the host 10 and its internal components is shown, in which the motor bracket 16, the motor 13, the motor lower cover 17, the power board protective cover 15 and the power board 14 are arranged from top to bottom. Compared with the previous horizontal parallel placement of the motor 13 and the power board 14, when the host 10 is placed on a workbench, its occupied space can be reduced, and the host 10 is easy to store.
[0052] The host 10 includes a main body 101, and a first opening is provided on the top of the main body 101, through which the power board assembly and the motor assembly can be installed in the main body 10, and a second opening is provided at the bottom of the main body 101, and the second opening is closed by a base 102, wherein the base 102 and the main body 101 can be an integral part or a split part, and an air inlet 103 and an air outlet 104 are provided on the base 102. When the machine is working, external air flows into the host 10 from the air inlet 103, first dissipates the heat of the power board 14, and then the air flow goes upward to dissipate the heat of the motor 13, and finally the hot air flows out from the air outlet 104 to complete the heat dissipation of the motor 13 and the power board 14. By optimizing the heat dissipation path in a limited axial space, while ensuring good heat dissipation, it is beneficial to improve the noise reduction effect.
[0053] When the main body 101 and the base 102 are separate parts, such as Fig.13As shown, the main body 101 and the motor bracket 16 can be fixed first, and then the base 102 can be buckled on the bottom of the main body 101 for fixing, which is convenient for operation. Further, a control panel 22 is installed on the front end surface of the main body 101, and an operation panel 23 is arranged outside the control panel 22. The user can control the machine through the operation panel 23. Placing the control panel 22 vertically can further reduce the radial size of the host 10 and promote the miniaturization of the whole machine.
[0054] like Figure 3 As shown, the power board protective cover 15 and the power board 14 enclose a first horizontal heat dissipation channel 12, one end of the first heat dissipation channel 12 is provided with a first air inlet channel 151 connected thereto, and the other end of the first heat dissipation channel 12 is provided with an air outlet channel 152 connected thereto, thereby, external airflow can flow along the path through the air inlet hole 103-first air inlet channel 151-first heat dissipation channel 12 to achieve heat dissipation for the power board 14, and then the airflow flows upward to the motor 13 through the air outlet channel 152, thereby dissipating the heat of the motor 13.
[0055] The power board 14 has a heating area, for example, which generates a large amount of heat. By arranging the first heat dissipation channel 12 at the heating area, it is beneficial to focus the heat dissipation in the heating area, so as to ensure that the overall temperature of the power board 14 will not be too high. Figure 3 As shown, the heat generating area is provided with a plurality of heat sinks 141 arranged at intervals, the heat sinks 141 extend in a horizontal direction, a gap is formed between two adjacent heat sinks 141, and the extending direction of the gap is the same as the flow direction of the airflow.
[0056] Since heat is directly dissipated from the surface of the components to the air, the heat dissipation area is small and the heat dissipation effect is poor. In this application, by setting a heat sink 141, the components in the heat-generating area first conduct the heat to the heat sink 141 when dissipating heat, and then dissipate the heat through the heat sink 141, which has a larger heat dissipation area. When the airflow passes through, the heat can be quickly taken away, and efficient heat dissipation can be achieved. Specifically, when the airflow flows along the first heat dissipation channel 12, it can flow along the gap to take away the heat on the surface of the heat sink 141. The extension direction of the gap is the same as the flow direction of the airflow, which can avoid blocking the airflow flow, making the airflow flow smoother, and can further optimize the heat dissipation effect of the power board 14.
[0057] exist Figure 3 In the example, the heat sink 141 extends laterally, for example. It can be understood that in other embodiments, the heat sink 141 can also be tilted to form a certain angle with the airflow direction, and the heat sink 141 can be prevented from being perpendicular to the airflow direction and blocking the airflow.
[0058] By providing a plurality of heat sinks 141, the heat dissipation area can be increased, and the air flow can quickly take away the heat when passing through, thereby achieving efficient heat dissipation. The power board 14 is suspended relative to the base 102, and the air inlet 103 is, for example, provided at the front end of the base 102, and the air outlet 104 is provided at the rear end of the base 102. Figure 3 As shown, after the airflow enters the main unit 10 from the air inlet 103 , it flows horizontally through the heating area and takes away the heat of the power board 14 , thereby achieving heat dissipation of the power board 14 .
[0059] In one embodiment, if Figure 8 and Fig. 9 As shown, the power board protective cover 15 is provided with a receiving groove 153, which can be used to accommodate multiple heat sinks 141. One end of the receiving groove 153 is connected to the first air inlet channel 151, which opens downward and can be connected to the air inlet hole 103 on the base 102. The other end of the receiving groove 153 is connected to the air outlet channel 152, which opens upward, so that the airflow can flow upward to the motor 13. Further, the power board protective cover 15 is also provided with a plurality of avoidance grooves 154 on one side of the receiving groove 153, which are used to avoid the components on the power board 14. The power board 14 can be fixed to the power board protective cover 15 by screws. The lower surface of the power board protective cover 15 is provided with a screw column 155, and the corresponding position of the power board 14 is provided with a screw hole. By inserting the screws, the installation can be simplified and fixed firmly. Further, a cylindrical support foot 156 is provided at the edge of the power board protective cover 15, and a shock-absorbing pad 132 can be provided in the support foot 156 to make the power board protective cover 15 and the base 102 flexibly abut. Further, such as Fig.12 As shown, the motor lower cover 17 is provided with a third fixing column 175, and the power board protective cover 15 is provided with a corresponding mounting sleeve 159. The mounting sleeve 159 can be mounted on the third fixing column 175, and then the power board protective cover 15 can be fixed by screwing the mounting sleeve 159 through the third fixing column 175.
[0060] In one embodiment, a second air inlet channel 171 extending downward is provided at the edge of the lower surface of the motor lower cover 17, and the motor bracket 16 and the motor lower cover 17 form a housing cavity that wraps the motor 13, and the housing cavity is provided with an air inlet, so that the airflow can enter the housing cavity along the air outlet channel 152-the second air inlet channel 171-the air inlet to dissipate the heat of the motor 13. Figure 4 The flow path of the airflow in the accommodating cavity is shown. For example, a second heat dissipation channel 172 is formed in the accommodating cavity. The airflow flows from the first heat dissipation channel 12 to the second heat dissipation channel 172. The entire air inlet path is constantly turning, which is conducive to extending the path, increasing the heat dissipation area and improving the heat dissipation effect. The motor 13 is provided with a heat dissipation fan 131. The rotation of the heat dissipation fan 131 forms a negative pressure in the host 10, which can prompt the airflow to enter the accommodating cavity faster to dissipate the heat of the motor 13, and then the hot airflow can be blown out in time to improve the heat dissipation efficiency.
[0061] Furthermore, in one embodiment, an exhaust channel 157 is also provided on one side of the air outlet channel 152, and the motor lower cover 17 is provided with an air outlet. The upper end of the exhaust channel 157 is connected to the air outlet, and the lower end of the exhaust channel 157 extends outward to be connected to the air outlet 104 on the bottom side wall of the main unit 10.
[0062] Specifically, after the airflow takes away the heat of the motor 13, it can flow from the accommodating cavity through the air outlet into the exhaust channel 157, and finally be discharged from the air outlet 104 on the host 10, wherein the air outlet, for example, extends downward to form a connecting channel, and the connecting channel can be connected with the exhaust channel 157 to achieve air discharge, thereby avoiding air leakage. Figure 5 As shown, when the hot air flows along the exhaust channel 157, it can turn a certain angle (for example, 100 degrees) and then be discharged from the side air outlet 104, which extends the air outlet path and is conducive to noise reduction. In addition, when the air flows downward along the exhaust channel 157, it can directly blow the noise reduction member 158 (the noise reduction member 158 is arranged at the bottom of the exhaust channel 157), and the noise reduction member 158 can absorb part of the noise, making the noise reduction effect more obvious. The noise reduction member 158 is, for example, a noise reduction sponge or a silicone member.
[0063] As a preferred embodiment, a flexible pad 18 is sandwiched between the motor bracket 16 and the motor 13 ; a shock-absorbing pad 132 is installed on the motor 13 to be isolated from the motor bracket 16 and the motor lower cover 17 by the shock-absorbing pad 132 .
[0064] As shown in FIG. 2 , the flexible pad 18 is added. On the one hand, a soft connection can be formed between the motor 13 and the motor bracket 16, which can prevent the vibration of the motor 13 from being transmitted upward and causing the cup body assembly 11 to work unstably. On the other hand, it can block noise and prevent the noise of the motor 13 from being transmitted upward, which is beneficial to reducing the working noise of the food processor; the shock-absorbing pad 132 of the motor 13 can further isolate the motor 13 from the motor bracket 16 and the motor lower cover 17, which can prevent the vibration of the motor 13 from being transmitted upward and downward, avoid collision between structural parts and induce resonance to increase noise, and further reduce the working noise.
[0065] Furthermore, the flexible pad 18 has a first annular rib 181 extending downward, the motor bracket 16 has a second annular rib 161, and the motor 13 is radially wrapped in sequence by the first annular rib 181 and the second annular rib 161.
[0066] The flexible pad 18 has a top wall and a first annular rib 181 connected to the top wall. The motor 13 is radially wrapped by a double-layer structure of the first annular rib 181 and the second annular rib 161, which can prevent the noise of the motor 13 from being transmitted radially. The first annular rib 181 is conveniently clamped by the motor bracket 16 and the motor lower cover 17, which can enhance the reliability of the installation of the flexible pad 18. The clamping of the flexible pad 18 helps to prevent the noise from being transmitted outward, thereby optimizing the noise reduction effect.
[0067] Preferably, the bottom end of the first annular rib 181 is provided with an outwardly protruding flange 182. When assembling the motor assembly, the bottom surface of the second annular rib 161 and the annular top surface of the motor lower cover 17 can be used to clamp the flange 182 to further optimize the clamping effect of the flexible pad 18.
[0068] Furthermore, the motor bracket 16 is provided with a first fixing column 162 extending downward, the flexible pad 18 is provided with a first mounting hole 183, the motor 13 is provided with a second mounting hole 133, and the motor lower cover 17 is provided with a third mounting hole 173. The first mounting hole 183, the second mounting hole 133 and the third mounting hole 173 are coaxially arranged, and the fastener passes through the third mounting hole 173, the second mounting hole 133 and the first mounting hole 183 and is fastened in the first fixing column 162.
[0069] like Fig.10 As shown, when assembling the motor assembly, the components can be placed upside down, the flexible pad 18 is placed on the first fixing column 162 through the first mounting hole 183, and then the second mounting hole 133 and the third mounting hole 173 are aligned with the hollow first fixing column 162 in sequence, and finally the fastener (such as a screw) is inserted from the third mounting hole 173 to fasten the fastener in the first fixing column 162. By using the same fastener to complete the installation of the motor bracket 16, the flexible pad 18, the motor 13 and the motor lower cover 17 together, fewer accessories are used, and the installation steps are simple, which can greatly simplify the installation process and improve efficiency.
[0070] As a preferred embodiment, the host 10 is further provided with an air duct assembly, and the air duct assembly is arranged between the motor lower cover 17 and the power board protective cover 15. An exhaust duct is provided between the motor lower cover 17 and the air duct assembly, and the exhaust duct extends downward in a spiral.
[0071] The setting of the air duct assembly can, on the one hand, extend the exhaust path, which is beneficial to heat dissipation and noise reduction, and on the other hand, increase the isolation between the motor 13 and the power board 14, which can prevent the two from transferring heat to each other and enhance the heat insulation effect. The exhaust duct extends downward in a spiral, which means that the exhaust duct is spiral and has a certain height in the axial direction, that is, the duct is not on the same plane, which can greatly extend the exhaust path, so that during the heat dissipation process, the accompanying noise can be frequently reflected and refracted, which can effectively enhance the noise attenuation effect and improve the noise reduction effect.
[0072] In one embodiment, the air duct assembly includes an air duct body 19 and an air duct cover 191 arranged at the bottom of the air duct body 19, the upper surface of the air duct body 19 and the motor lower cover 17 are combined to form a first exhaust duct 20, and the lower surface of the air duct body 19 and the air duct cover 191 are combined to form a second exhaust duct 21, and the first exhaust duct 20 and the second exhaust duct 21 constitute a double-layer spiral duct.
[0073] In this embodiment, the exhaust duct includes a first exhaust duct 20 and a second exhaust duct 21 which are connected to each other, so that the total rotation angle of the exhaust air exceeds 360°, which can effectively improve the noise reduction effect while dissipating heat.
[0074] like Figure 6 and Figure 7 As shown, the first exhaust duct 20 extends in an arc shape (major arc), and the motor lower cover 17 is provided with an air outlet. After the motor 13 dissipates heat, the air flow flows into the first exhaust duct 20 from the air outlet, and then the air flow flows into the second exhaust duct 21. The second exhaust duct 21 extends in an arc shape (major arc), and then the air flow can be guided to the air outlet 104 through the structure on the power board protective cover 15 (such as the above-mentioned exhaust channel 157) to achieve exhaust.
[0075] Further, to realize the installation of the air duct assembly, such as Fig.11 As shown, the motor lower cover 17 is provided with a second fixing column 174, and the air duct assembly is provided with a fourth mounting hole 192, and a fastener passes through the fourth mounting hole 192 and is fastened to the second fixing column 174. The fastener is, for example, a screw, and the screw fixation has a simple structure and is reliable in use. Among them, the fourth mounting hole 192 can be set on the air duct body 19 or on the air duct cover 191. For example, Fig.11 As shown, the air duct cover 191 is provided with a first lug, and the first lug is provided with a fourth mounting hole 192. Correspondingly, the air duct body 19 is provided with a second lug, and the second lug is provided with a fifth mounting hole. After aligning the fourth mounting hole 192, the fifth mounting hole and the second fixing column 174, the same fastener can be used to realize the assembly of the air duct cover 191 and the air duct body 19 and the fixation of the air duct assembly to the motor lower cover 17. The installation steps are simple and efficient.
