Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a food processor. Background Technology

[0002] In current technology, a food processor includes a base and a cup assembly. The cup assembly includes a blending blade, a motor, and a cooling fan. When the cup assembly is installed on the base, the motor and the base are electrically connected.

[0003] Since the heat of the motor is dissipated through the airflow channel during operation, there are usually vents on the cup body assembly. When the cup body assembly is removed from the base for cleaning, water can easily enter the cup body through the vents, affecting the normal use of the motor and possibly even damaging it. Utility Model Content

[0004] To address at least one problem existing in the prior art, according to one aspect of the present invention, a food processor is provided, comprising:

[0005] The base has a mounting cavity, and the base has a pushing structure inside the mounting cavity;

[0006] The food processor assembly is detachably installed in the mounting cavity and includes a cup body, a stirring blade, a cover, a drive motor, a control panel, and a cooling fan. The stirring blade is located inside the cup body, and the cover is connected to the bottom of the cup body and has a cavity for installing the drive motor, control panel, and cooling fan. The two ends of the output shaft of the drive motor are respectively connected to the stirring blade and the cooling fan. The cover has an air vent communicating with the cavity.

[0007] A blocking structure is movably mounted on the air vent to open the air vent when the cooking cup assembly is installed in the mounting cavity, and to block the air vent when the cooking cup assembly is removed from the mounting cavity.

[0008] In some embodiments, the blocking structure is disposed within the cover body, and the pushing structure is inserted into the cover body when the cooking cup assembly is installed on the base.

[0009] In some embodiments, the air vent includes an air outlet, and the push structure includes an air outlet push structure. The air outlet push structure has an inclined wall opposite to the airflow direction inside the cover, and the inclined wall is inclined downward toward the outside of the base.

[0010] In some embodiments, the air outlet push structure further includes a top wall and two opposing side walls, the top wall being connected to the top of the inclined wall and the top of the side walls respectively, for resisting the blocking structure when a push force is applied to the blocking structure.

[0011] In some embodiments, the air outlet further includes an air inlet, and the pushing structure includes an air inlet pushing structure;

[0012] Both the air inlet and the air outlet are located at the bottom of the cover;

[0013] An airflow channel is formed inside the cover and is connected to the air inlet and air outlet. The air inlet blocking structure is located inside the airflow channel.

[0014] In some embodiments, the cover includes a separate shroud and an outer shell. The shroud has the cavity and an open end. The drive motor is located at the open end. The outer shell covers the shroud and forms the airflow duct between the outer shell and the shroud.

[0015] In some embodiments, the fan cover includes an upper mounting section, a lower mounting section, and an air outlet section. The upper mounting section is used to house the control panel and at least part of the drive motor. The lower mounting section is used to house the cooling fan. The inner diameter of the upper mounting section is larger than the inner diameter of the lower mounting section. The air outlet section is located at the bottom of the upper mounting section, communicates with the inner cavity of the lower mounting section, extends radially along the lower mounting section, and forms an air outlet channel opposite to the air outlet. The air outlet blocking structure is movably disposed within the air outlet channel.

[0016] In some embodiments, when the air inlet blocking structure and the air outlet blocking structure are in the open state for the air inlet and the air outlet respectively, the air inlet blocking structure and the air outlet blocking structure are respectively attached to the lower surface of the upper mounting section.

[0017] In some embodiments, the blocking structure includes an elastic element, a connector, and a flexible seal. The two ends of the elastic element abut against the cover and the connector, respectively, and the flexible seal is connected to the connector for sealing or opening the air vent.

[0018] In some embodiments, the control panel is located between the drive motor and the cooling fan, the output shaft of the drive motor passes through the control panel, and the control panel is provided with a clearance for the output shaft to pass through.

[0019] In summary, the food processor provided by this utility model has the following technical effects:

[0020] By mounting the control panel and drive motor together within the housing, when the cooling fan drives airflow within the cavity, the airflow not only cools the drive motor but also simultaneously cools the control panel, extending its lifespan. Simultaneously, a push-pull structure on the base blocks the air vents when the blending cup assembly is disassembled for cleaning, preventing water from entering and ensuring the safety of the internal structure during subsequent use. This also prevents insects, dust, and other impurities from entering the blending cup assembly. When the blocking structure opens the air vents, the heat generated by the drive motor and other components during operation can dissipate through the vents, ensuring the normal lifespan of the drive motor.

Detailed Implementation

[0040] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings.

[0044] Please see Figures 1 to 18 The food processor 100 provided in this embodiment of the present utility model includes a base 10, a food processor cup assembly 20, and a blocking structure 30.

[0045] Please refer to Figures 1 to 4 The base 10 has an installation cavity 11, and the base 10 has a push structure 12 inside the installation cavity 11. The food preparation cup assembly 20 is detachably installed in the installation cavity 11 and includes a cup body 21, a stirring blade 22, a cover 23, a drive motor 24, a control panel 25, and a cooling fan 26. The stirring blade 22 is located inside the cup body 21. The cover 23 is connected to the bottom of the cup body 21 and has a cavity 231 for installing the drive motor 24, the control panel 25, and the cooling fan 26. The two ends of the output shaft 241 of the drive motor 24 are respectively connected to the stirring blade 22 and the cooling fan 26. The cover 23 has an air vent 27 that communicates with the cavity 231. The blocking structure 30 is movably installed on the air vent 27 to open the air vent 27 when the food preparation cup assembly 20 is installed in the installation cavity 11 and to block the air vent 27 when the food preparation cup assembly 20 is removed from the installation cavity 11.

[0046] The aforementioned food processor 100, by mounting the control panel 25 and drive motor 24 together inside the housing 23, allows the cooling fan 26 to drive airflow within the cavity 231, which not only cools the drive motor 24 but also simultaneously cools the control panel 25, thus extending the lifespan of the control panel 25. Simultaneously, by providing a push-pull structure 12 on the base 10, the blocking structure 30 blocks the air vent 27 when the food processor assembly 20 is disassembled for cleaning, preventing water from entering the food processor assembly 20 and ensuring the safety of the internal structure during subsequent use. It also prevents insects, dust, and other impurities from entering the food processor assembly 20. When the blocking structure 30 opens the air vent 27, the heat generated by the drive motor and other structures during operation can be dissipated through the air vent 27, ensuring the normal lifespan of the drive motor.

[0047] Specifically, in this embodiment, when the blocking structure 30 is installed on the cooking cup assembly 20, the blocking structure 30 is located inside the cover 23. When the cooking cup assembly 20 is installed on the base 10, the pushing structure 12 is inserted into the cover 23. Thus, after the pushing structure 12 is inserted into the air vent 27, it applies an upward pushing force to the blocking structure 30, thereby causing the blocking structure 30 to move away from the air vent 27 and opening the air vent 27. By placing the blocking structure 30 inside the cover 23, the cooking cup assembly 20 can function as a whole, with the cover 23 providing support. The blocking structure 30 is shielded to ensure the consistency of appearance. When the cooking cup assembly 20 is installed on the base 10, the bottom wall and side wall 126 of the cooking cup assembly 20 are respectively fitted with the cavity wall of the mounting cavity 11, which can be waterproof during use. In other embodiments, the air vent 27 can be provided on the side wall 126 of the cover 23, and the blocking structure 30 is slidably disposed on the side wall of the cover 23. The pushing structure 12 applies a pushing force to the blocking structure 30 on the side wall 126, which can also achieve the effect of driving the blocking structure 30 to open the air vent.

[0048] Please refer to Figures 5 to 10In this embodiment, the cover 23 is provided with two air vents 27, which are defined as air inlet 271 and air outlet 272; the food processor 100 includes two blocking structures 30, which correspond to the air inlet 271 and air outlet 272 respectively, and are defined as air inlet blocking structure 35 and air outlet blocking structure 36 respectively; the base 10 includes two pushing structures 12, which are defined as air inlet pushing structure 121 and air outlet pushing structure 122 respectively, for air inlet pushing structure 121 and air outlet pushing structure 122. Structure 121 corresponds to air inlet 271, and air outlet push structure 122 corresponds to air outlet 272. Air outlet push structure 122 has an inclined wall 123 that is opposite to the airflow direction in the wind hood 232. The inclined wall 123 is inclined downward towards the outside of the base 10. In this way, the inclined wall 123 on the air outlet push structure 122 can guide the airflow out and tilt the airflow downward to disperse the airflow and avoid the airflow directly hitting the bottom wall of the mounting cavity 11 and causing noise.

[0049] Further, please refer to Figures 14 to 16 To ensure stability when a jacking force is applied to the blocking structure 30, the air outlet jacking structure 122 also includes a top wall 127 and two opposing side walls 126. The top wall 127 is connected to the top of the inclined wall 123 and the top of the side walls 126, respectively, to resist the blocking structure 30 when a jacking force is applied. The air outlet jacking structure 122 also has an opening 125 and an air guide cavity 124 formed inside. The airflow flows into the air guide cavity 124 and flows out along the inclined wall 123. By setting the top wall 127, it can have a large contact area with the blocking structure 30, ensuring the stability of the jacking when an upward jacking force is applied to the jacking structure 12. At the same time, when the blocking structure 30 is opened, it has a large contact area with the blocking structure 30, ensuring the stability of the support.

[0050] Please see Figures 4 to 10 In one embodiment of this utility model, when the air inlet blocking structure 35 and the air outlet blocking structure 36 are installed, the air inlet 271 and the air outlet 272 are both located at the bottom of the cover 23, and an airflow channel 234 is formed inside the cover 23. The air inlet blocking structure 35 is located inside the airflow channel 234, and the air outlet blocking structure 36 is located inside the wind cover 232. In this way, by setting the air inlet 271 and the air outlet 272 at the bottom of the cover 23, the air inlet and outlet positions are the same as the base 10, ensuring the integrity of the side position of the cover 23. Moreover, the way the airflow channel 234 is set can realize the connection between the air inlet 271 and the air outlet 272, and realize the circulation of airflow.

[0051] Specifically, please refer to Figures 6 to 13When the cover 23 is installed, the cover 23 includes a separate wind cover 232 and a shell 233. The wind cover 232 has a cavity 231 and an open end 235. The drive motor 24 is located at the open end 235. The shell 233 covers the wind cover 232 and forms an airflow channel 234 between the shell 232 and the wind cover 232. The shell 233 has an air inlet and an air outlet. In this way, the cover 23 is installed in a separate manner, which facilitates the installation of the entire cover and the installation of each component inside the cover 23.

[0052] Specifically, please refer to Figures 11 to 13 The fan cover 232 comprises three parts: an upper mounting section 2321, a lower mounting section 2322, and an air outlet section 2323. The upper mounting section 2321 houses the control panel 25 and at least part of the drive motor 24. The lower mounting section 2322 houses the cooling fan 26. The inner diameter of the upper mounting section 2321 is larger than that of the lower mounting section 2322. The air outlet section 2323 is located at the bottom of the upper mounting section 2321 and communicates with the inner cavity of the lower mounting section 2322. Extending radially along the lower mounting section 2322, it forms an air outlet channel 2327 that connects with the air outlet 272. The air outlet blocking structure 36 is movably disposed within the air outlet channel 2327. Thus, by configuring the hood 232 to include an upper mounting section 2321 and a lower mounting section 2322 with different inner diameters, the airflow can generate a pressure difference and converge towards the lower mounting section 2322 before flowing out, and the airflow can spiral out along the wall of the air outlet section 2323. Specifically, one of the two blocking structures 30 is disposed at the bottom of the upper mounting section 2321, and the other is disposed within the air outlet section 2323, thereby respectively blocking and opening the air inlet 271 and the air outlet 272.

[0053] Please refer to Figure 10 and Figure 11 Since the blocking structure 30 is located in the airflow channel 234, in order to avoid the blocking structure 30 obstructing the airflow when the air outlet 27 is open, when the inlet blocking structure 35 and the outlet blocking structure 36 are open to the air inlet 271 and the air outlet 272 respectively, the inlet blocking structure 35 and the outlet blocking structure 36 are respectively attached to the lower surface of the upper mounting section 2321. In this way, the resistance of the blocking structure 30 to the airflow in the airflow channel 234 is reduced.

[0054] Specifically, in implementation, please refer to Figure 17 and Figure 18 The blocking structure 30 includes an elastic element 31, a connector 32, and a flexible sealing element 33. The two ends of the elastic element 31 abut against the cover 23 and the connector 32, respectively. The flexible sealing element 33 is connected to the connector 32 and is used to block or open the air vent 27.

[0055] When the air inlet 271 or the air outlet 272 is opened, the push structure 12 applies pressure to the flexible seal 33, compressing the elastic element 31. The flexible seal 33 moves away from the air outlet 27, allowing the air outlet 27 to open. When the cooking cup assembly 20 is taken out for use alone, the flexible seal 33 is pressed against the air outlet 27 by the elastic force, thus sealing the air outlet 27. Due to the flexible seal 33, it can be sealed at the air outlet 27 by the elastic force of the elastic element 31, ensuring a sealing effect.

[0056] The flexible seal 33 can be made of silicone, which seals the vent 27 by deforming the silicone. In other embodiments, it can also be made of other plastic parts with plastic deformation.

[0057] Specifically, please refer to Figure 17 When connecting the connector 32 and the flexible seal 33, in order to ensure the connection stability between the flexible seal 33 and the connector 32, the flexible seal 33 covers the connector 32, and the connector 32 is exposed relative to the flexible seal 33. In this way, by covering the connector 32, the connection stability between the flexible seal 33 and the connector 32 is ensured. At the same time, the connector 32 is exposed relative to the flexible seal 33, and the exposed part can be connected with the elastic member 31 so that the rigid connector 32 can receive the elastic force from the elastic member 31 and apply an upward pushing force to the elastic member 31.

[0058] Further, please refer to Figure 10 When sealing the air vent 27, the flexible sealing element 33 seals the inner surface of the outer casing 233. Specifically, the flexible sealing element 33 is provided with a guide platform 331. The cross-sectional area of ​​the guide platform 331 in the horizontal direction is smaller than the cross-sectional area of ​​the flexible sealing element 33 in the horizontal direction. The guide platform 331 is used to extend into the diameter of the air vent 27 when the flexible sealing element 33 seals the air vent 27. In this way, the guide platform 331 extends into the air vent 27, so that the inner side of the outer casing 233 can fully contact the surface of the flexible sealing element 33, thereby increasing the sealing effect.

[0059] Understandably, since the guide platform 331 needs to extend into the air vent 27, in order to facilitate the extension of the guide platform 331, the outer edge of the guide platform 331 is a guide sidewall 332. The guide sidewall 332 is inclined downward towards the center of the air vent 27, so that the setting of the guide sidewall 332 can have a guiding function, facilitating the extension of the guide platform 331 into the air vent 27.

[0060] Further, please refer to Figure 11 and Figure 17To facilitate the installation of the elastic element 31, the shroud 232 forms a receiving groove 2324 in the direction away from the bottom wall of the outer shell 233. The connector 32 is provided with a guide post 321. One end of the elastic element 31 abuts against the top wall of the receiving groove 2324, and the other end is sleeved on the guide post 321. Through the setting of the receiving groove 2324 and the guide post 321, the receiving groove 2324 can receive the end of the elastic element 31, and the guide post 321 can be used to sleeve the elastic element 31, thereby realizing the installation of the elastic element 31. At the same time, it can also guide the expansion and contraction of the elastic element 31 along its own axis.

[0061] Please refer to Figure 9 Since the blocking structure 30 is located in the airflow channel 234, in order to avoid excessive obstruction of the airflow when the blocking structure 30 opens the air outlet 27, the cross-sectional area of ​​the guide post 321 in the horizontal direction is smaller than the cross-sectional area of ​​the receiving groove 2324 in the horizontal direction. As a result, when the blocking structure 30 opens the air outlet 27, the guide post 321 can be inserted into the receiving groove 2324, so as to achieve the effect of the lower surface of the connector 32 and the upper mounting section 2321 fitting together, thereby reducing the impact of the blocking structure 30 on the airflow.

[0062] Please see Figure 11 In one embodiment of this utility model, when the blocking structure 30 slides relative to the wind shield 232, the wind shield 232 extends a guide wall 2325 towards the bottom wall of the outer shell 233. The blocking structure 30 and the guide wall 2325 are slidably arranged. The arrangement of the guide wall 2325 restricts the up-and-down sliding of the blocking structure 30, thereby ensuring the stability of the up-and-down sliding of the blocking structure 30.

[0063] To reduce the frictional resistance of the blocking structure 30 sliding up and down, a groove 2326 is provided on the guide wall 2325, and a slider 34 is provided on the blocking structure 30. The slider 34 is slidably disposed in the groove 2326. In this way, since the contact area between the slider 34 and the groove wall of the groove 2326 is small, the frictional force of the blocking structure 30 when sliding up and down can be reduced, thus ensuring the stability of the blocking structure 30 in its up and down movement.

[0064] In this embodiment, the air vent 27 includes two vents: an air inlet 271 and an air outlet 272. When the blocking structure 30 at the air outlet 272 slides relative to the hood 232, a sliding groove is directly provided on the side wall 126 of the air outlet section 2323, and a slider 34 is provided on the connector 32. The slider 34 slides relative to the sliding groove 2326, which enables the blocking structure 30 to slide up and down.

[0065] Furthermore, when the blocking structure 30 located at the air inlet 271 is slidably set, the bottom wall of the upper mounting section 2321 extends into a guide wall 2325 towards the bottom wall of the outer casing 233. Specifically, two opposing guide walls 2325 extend out. The connector 32 is provided with two sliders 34, and one slider 34 is slidably set in the groove 2326 of one guide wall 2325. In this way, the setting of the two guide walls 2325 can ensure the stability of the blocking structure 30 in the vertical direction.

[0066] Please see Figures 9 to 13 In one embodiment of this utility model, it can be understood that the drive motor 24 includes a housing 233, a stator and a rotor disposed within the housing 233, and also includes an output shaft 241 connected to a cooling fan 26, thereby driving the cooling fan 26 to rotate. When the drive mechanism is applied to the food processor 100, the output shaft 241 of the drive motor 24 includes two output ends, one output end for connecting to the mixing blade 22, and the other output end for connecting to the cooling fan 26.

[0067] In this embodiment, the output shaft 241 passes through the control panel 25, meaning the control panel 25 is arranged in a ring shape, surrounding the output shaft 241. Compared to the prior art where the control panel 25 is placed in the base 10, this increases the coverage area of ​​the control panel 25 and the contact area between the control panel 25 and the airflow, achieving rapid heat dissipation. Since the control panel 25 includes a circuit board and electronic components mounted on it, this effectively increases the airflow contact area of ​​the circuit board, thereby improving heat exchange efficiency.

[0068] Further, please refer to Figure 9 and Figure 10 In one embodiment of this utility model, in order to avoid the drive motor 24 transferring too much heat to the control panel 25 during operation, the drive motor 24 and the control panel 25 are spaced apart. Thus, by setting the distance between the two, not only can the heat transfer from the rotor of the drive motor 24 to the control panel 25 during operation be reduced, but the distance between the two can also help the airflow and achieve heat dissipation of the control panel 25.

[0069] The spacing ranges from 3.0cm to 5.0cm. This spacing setting ensures that the distance between the two components is not too large, avoiding excessive vertical space occupation when installed on the machine. It also prevents the distance from being too small, which would obstruct heat transfer from the drive motor 24 to the control panel 25, and also avoids obstructing airflow to the control panel 25. For example, the distance between them can be set to values ​​such as 3.0cm, 4.0cm, or 5.0cm, and is not limited here.

[0070] Please see Figure 12 In one embodiment of this utility model, since the control panel 25 includes a circuit board and electronic devices disposed on the circuit board, in order to avoid the influence of high heat on the control panel 25, the electronic devices are disposed on the side of the circuit board facing the cooling fan 26. In this way, the electronic devices are disposed away from the drive motor 24, avoiding the direct transfer of heat from the drive motor 24 to the electronic devices, and reducing the influence of the heat generated by the drive motor 24 on the control panel 25.

[0071] Understandably, there is also a gap between the electronic components and the cooling fan 26 so that the airflow can flow towards the cooling fan 26 after passing through the control panel 25, so that the airflow can carry away the heat generated on the control panel 25 and achieve heat dissipation of the control panel 25.

[0072] In the prior art, the control panel 25 is mounted on the base 10, resulting in a small contact area with the airflow. The control panel 25 is also equipped with multiple heat dissipation fin groups, each of which includes at least 10 heat dissipation fins arranged in parallel. This allows for heat exchange between the multiple heat dissipation fin groups and the airflow, thereby quickly dissipating the heat from the control panel 25 during use.

[0073] Please see Figure 9 and Figure 10 In one embodiment of this utility model, the control panel 25 is also provided with a heat dissipation fin assembly 253. However, since the control panel 25 is located between the drive motor 24 and the cooling fan 26, it can have a large contact area with the airflow. Therefore, compared with the prior art method of setting heat dissipation fins on the control panel 25, this embodiment only needs to set one heat dissipation fin assembly 253, and the number of heat dissipation fins is in the range of 7-11. Since the control panel 25 already has a large contact area with the airflow, setting one heat dissipation fin and setting a small number of heat dissipation fins can quickly achieve the cooling of the control panel 25.

[0074] In one embodiment, when installing the control panel 25, since the output shaft 241 of the drive motor 24 passes through the control panel 25, i.e., the control panel 25 surrounds the output shaft 241, a mounting post is provided on the side of the drive motor 24 housing facing the control panel 25 to facilitate the installation of the annular control panel 25. The control panel 25 has mounting holes, and the mounting holes and mounting post are connected by bolts. Thus, by providing mounting holes and mounting posts, and connecting them with bolts, the control panel 25 is fixed. In another embodiment, a supporting step can be formed on the inner wall of the fan cover 232 to support the control panel 25, thereby facilitating its installation.

[0075] Understandably, since the control panel 25 has a large cross-sectional area, in order to ensure the installation stability of the control panel 25, the housing is provided with multiple mounting posts and the control panel 25 is provided with multiple mounting holes. The multiple mounting posts and multiple mounting holes are connected one-to-one. In this way, through the arrangement of multiple mounting holes and multiple mounting posts, the control panel 25 can have multiple connection points with the housing of the drive motor 24. The multiple connection points share the tensile force and gravity from the control panel 25, thus ensuring the installation stability of the control panel 25.

[0076] Furthermore, since the control panel 25 and the cooling fan 26 are coaxially arranged, that is, the output shaft 241 of the drive motor 24 passes through the control panel 25 and is connected to the drive motor 24, the drive motor 24 drives the cooling fan 26 to rotate during operation. In order to avoid driving the control panel 25 to rotate, the control panel 25 is provided with a clearance opening 251 for the output shaft 241 to pass through. The distance between the side wall of the clearance opening 251 and the output shaft 241 is 2cm-5cm, that is, a large clearance opening 251 is provided in the middle of the control panel 25. The output shaft 241 passes through the clearance opening 251 to connect with the cooling fan 26. Furthermore, by setting a certain distance between the clearance opening 251 and the output shaft 241, when the airflow flows from the upper part of the fan cover 232 to the lower part, the airflow flows through the clearance opening 251, which helps the airflow to flow downward and helps to dissipate heat from the control panel 25.

[0077] The distance between the side wall 126 of the clearance opening 251 and the pivot can be set to a value of 2cm, 3cm, 4cm or 5cm, etc., and is not limited here.

[0078] Further, please refer to Figure 13When installing the control panel 25, it is fitted with the inner wall of the fan cover 232 with a gap to facilitate installation and reduce installation difficulty. For example, when the two are fitted with a gap, the gap range is set to 0-0.3mm, such as 0, 0.1mm, 0.2mm, 0.3mm, etc., to avoid the gap 231 being too large, which would prevent the airflow from flowing too much to the surface of the control panel 2530 and thus lose the heat dissipation effect on the control panel 2530.

[0079] Furthermore, when the inner wall gap between the control panel 25 and the fan shroud 232 is set, in order to ensure the efficiency of airflow flowing to the lower part of the fan shroud 232, the control panel 25 is provided with an airflow port 252 for airflow. Thus, through the setting of the airflow port 252, when the airflow flows over the control panel 25, it can flow downwards from the control panel 25, reducing wind resistance and improving the efficiency of airflow, so as to remove the heat generated on the control panel 25.

[0080] Specifically, in this embodiment, the flow port 252 extends to the edge of the control panel 25, thereby facilitating the setting of the flow port 252 on the control panel 25. Compared with the method of opening the flow port 252 in the middle area of ​​the control panel 25, the difficulty of opening the flow port 252 is reduced.

[0081] Understandably, in order to ensure the downward flow of air, the control panel 25 is provided with multiple airflow ports 252. The multiple airflow ports 252 are arranged circumferentially around the output shaft 241 on the control panel 25, so that the control panel 25 can be provided with airflow ports 252 at various positions near the fan cover 232, so that the airflow can flow downward from various areas of the control panel 25 and ensure the heat dissipation effect of the control panel 25.

[0082] The aforementioned food processor 100, by providing a push structure 12 on the base 10, can drive the blocking structure 30 to move to open the air vent 27 when the food processor cup assembly 20 is installed on the base 10, thereby achieving heat dissipation for the drive motor 24 and the control panel 25; by simultaneously setting the control panel 25 and the drive motor 24 within a cover 23, heat dissipation can be achieved by the cooling fan 26, thus extending the service life of the control panel 25.

[0083] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
