Description

Technical Field

[0001] The utility model relates to the field of food processors, and particularly relates to a food processor with optimized waterproof performance. Background Art

[0002] For a wall breaker with an upper-mounted motor, the motor is connected below the mixing cup and located inside the cup housing. To ensure heat dissipation, air inlet and outlet holes are usually designed at the bottom of the cup housing to ensure air circulation and achieve heat dissipation of the motor. When the cup assembly is placed on a liquid-containing tabletop or during cleaning, liquid easily enters the inside of the cup housing through the air inlet and outlet holes, increasing the risk of damaging the electronic devices inside the cup housing.

[0003] The existing patent CN113116184A discloses a food processor, including a machine base and a mixing cup. The machine base is provided with a heat dissipation channel, and a switchable sealing component is arranged at the heat dissipation channel to ensure that the sealing component is opened during the operation of the food processor so that the heat dissipation channel can be used normally, and water can be prevented from entering the machine base through the heat dissipation channel to damage the motor or other electronic devices during cleaning by closing the sealing component.

[0004] The mixing cup and the machine base of the above food processor are of an integrated structure, and the following problems exist during use: The sealing component needs to rely on the machine base being placed on the workbench to trigger the opening of the air inlet and outlet by the tabletop. During the operation of the machine, if the user picks up the machine and leaves the tabletop, the external force on the sealing component disappears, causing the air inlet and outlet to close. Since the machine is still operating, it will affect the normal heat dissipation of the machine, resulting in too high a temperature of the motor and affecting the performance and lifespan of the motor. Moreover, on the premise that the sealing component needs to be triggered by an external structure to open the air inlet and outlet, when the user picks up the machine base, the sealing component is normally closed. Psychologically, the user will think that the seal is reliable and thus take the waterproofing lightly. In fact, during the cleaning process, the user may accidentally trigger the sealing component to open the air inlet and outlet, causing the cleaning water to flow into the machine base through the air inlet and outlet, increasing the risk of water ingress instead. After the applicant of this application realized the above problems, for models with different structural compositions, the sealing method of the sealing structure was further improved, aiming to strengthen the reliability of the seal and reduce the risk of water ingress into related structures on the premise of ensuring the heat dissipation effect of the machine. Summary of the Utility Model

[0005] In order to solve the technical problems in the prior art that the sealing and waterproofing effect of the integrated wall-breaking machine is unreliable, and the heat dissipation of the machine is affected when the machine is off the table, the utility model provides a food processing machine with optimized waterproof performance.

Moreover, the heat dissipation can be ensured when the cup body assembly is placed on the main machine for operation. No heat dissipation is required after the cup body assembly is picked up, so there is no conflict with the sealing.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0018] 1. For the food processor with optimized waterproof performance of the utility model, when the cup body assembly is installed on the main body, the air inlet and the air outlet are opened, which can meet the heat dissipation requirements of the whole machine. When the cup body assembly is lifted, the machine stops working and there is no requirement for heat dissipation at this time. Therefore, it doesn't matter even if the air inlet and the air outlet are closed at this time. After the cup body assembly is removed from the main body, the shielding member can close the air inlet and the air outlet, thereby preventing water from entering the cup body housing from the air inlet and the air outlet during the cleaning process of the cup body assembly. Therefore, it can prevent the electronic devices in the cup body housing from being damaged and extend the service life of the electronic devices. Moreover, the stability of the shielding member closing the air inlet and the air outlet is good, which can improve the reliability of sealing and is beneficial to further reducing the risk of water ingress.

[0019] The action of the shielding member to open the air inlet and the air outlet is completed when the cup body assembly is installed on the main body, without the need for additional steps, which can save user operations and improve the user experience. An air inlet duct is provided inside the main body, which is beneficial to the heat dissipation of relevant components inside the main body, and the heat dissipation duct inside the cup body shell is beneficial to the heat dissipation of the motor, so that the heat of the motor can be discharged in time through the heat dissipation duct, avoiding heat residue and improving the heat dissipation effect of the motor.

[0020] 2. As a preferred embodiment, a power board is provided inside the main body. The power board includes a high-temperature area provided with an IPM module, and the air inlet duct covers the high-temperature area. By arranging the air inlet duct in the high-temperature area, centralized and rapid heat dissipation of the high-temperature area can be achieved. Under the action of the air inlet duct, not only can the aggregation of air flow be ensured to improve the uniformity of heat dissipation in the high-temperature area, but also it is beneficial to reduce noise. Arranging the air inlet duct in the high-temperature area can improve the heat dissipation effect compared with the conventional air flow passing through the power board in an open space, and can ensure the heat dissipation effect for the high-temperature area with high heat dissipation requirements.

[0021] 3. As a preferred embodiment, an air outlet duct is provided inside the main body. The main body is provided with an air flow outlet corresponding to the air outlet. One end of the air outlet duct is communicated with the air flow outlet, and the other end is communicated with the air outlet hole on the main body. When the cup body assembly is installed on the main body, the heat dissipation duct is communicated with the air outlet duct through the air outlet and the air flow outlet. By arranging the air outlet duct, during the operation of the machine, the heat of the motor can be discharged through the heat dissipation duct - air outlet duct - air outlet hole, which can ensure the heat dissipation efficiency, and at the same time can avoid part of the heat remaining in the main body causing the temperature rise of electronic devices in the main body to be too high and affecting their service performance and life, and can improve the heat dissipation reliability.

[0022] 4. As a preferred embodiment, the shielding member can move vertically relative to the cup body shell. When the cup body assembly is installed on the main body, the main body pushes the shielding member upward to open the air inlet and the air outlet. In this embodiment, the action of the shielding member to open the air inlet and the air outlet is triggered when the cup body assembly is installed, and the whole process is completed in one go without additional actions, which is simple and convenient for the user to operate.

[0023] 5. As a preferred embodiment, the host comprises a main body shell with an opening at the top and a concave main body cover installed at the opening, the bottom of the main body cover is provided with a first boss and a second boss corresponding to the air inlet and the air outlet respectively, the side wall of the first boss is provided with an airflow inlet, the side wall of the second boss is provided with an airflow outlet, and when the cup body assembly is installed on the host, the shielding member avoids the airflow inlet and the airflow outlet. The first boss and the second boss are provided, on the one hand, to facilitate the positioning of the cup body assembly during installation, so as to reduce the difficulty of installation of the cup body assembly and improve efficiency, and on the other hand, the airflow inlet and the airflow outlet are provided thereon to create conditions for the airflow connection between the host and the cup body assembly, so as to ensure normal heat dissipation when the machine is working, so that the electronic components and the outside of the host are kept at a good temperature, and the performance and life of the whole machine are improved.

[0024] Furthermore, the bottom of the cup body shell is provided with a first recessed portion and a second recessed portion for the first boss and the second boss to be plugged in respectively, the side wall of the first recessed portion is provided with the air inlet, and the side wall of the second recessed portion is provided with the air outlet. When the cup body assembly is installed on the host, the shielding member opens the air inlet and the air outlet to allow the air inlet to communicate with the air flow inlet, and the air outlet to communicate with the air flow outlet. By adopting the side openings of the air inlet and the air outlet, the cup body assembly can be placed alone on a table with liquid, or when the cup body assembly is cleaned, it can effectively prevent liquid from entering the cup body shell, and the waterproof effect is better than the method of directly opening holes in the bottom. When the cup body assembly is installed, the boss and the recessed portion can be plugged in and matched, so that the installation position of the cup body assembly can be accurately and quickly determined, which is conducive to one-step installation and can avoid multiple adjustments to the installation position that affect the installation efficiency.

[0025] 6. As a preferred embodiment, a return spring is provided above the shielding member, and when the cup assembly is separated from the host, the shielding member moves downward under the action of the return spring to block the connection between the air inlet and the air outlet and the inside of the cup shell.

The installation bracket in this embodiment can provide installation, movement guiding of the shielding member, and setting of the air inlet and the air outlet, serving multiple purposes with one component. Through the cooperation of the shielding member and the installation bracket, the compactness of the structure inside the cup body housing can be promoted.

[0027] Further, a rib is provided at the bottom of the mounting portion and can penetrate through the bottom wall of the cup body housing. The main body is provided with a protrusion.

[0045] As Figures 1 to 6 shown, the present application provides a food processor with optimized waterproof performance, including a main body 10 and a cup assembly 11 detachably installed on the main body 10. The cup assembly 11 includes a mixing cup 12 and a cup housing 13 provided below the mixing cup 12. The mixing cup 12 is provided with a crushing knife 121, and a motor 14 for driving the crushing knife 121 to rotate is provided in the cup housing 13. An air inlet duct is provided in the main body 10, a heat dissipation duct 15 is provided in the cup housing 13, the cup housing 13 is provided with an air inlet and an air outlet 16, and a shielding member 17 is movably installed in the cup housing 13. The shielding member 17 opens the air inlet and the air outlet 16 when the cup assembly 11 is installed on the main body 10, and the shielding member 17 blocks the communication between the air inlet and the air outlet 16 and the inside of the cup housing 13 when the cup assembly 11 is separated from the main body 10.

[0046] For the food processor with optimized waterproof performance in this application, when the cup body assembly 11 is installed on the main machine 10, the air inlet and outlet are opened, which can meet the heat dissipation requirements of the whole machine. When the cup body assembly 11 is lifted, the machine stops working and there is no requirement for heat dissipation at this time. Therefore, it doesn't matter if the air inlet and outlet are closed at this time. On the premise of meeting the heat dissipation requirements inside the cup body shell 13, after the cup body assembly 11 is removed from the main machine 10, the shielding member 17 can close the air inlet and outlet 16, thereby preventing water from entering the cup body shell 13 through the air inlet and outlet 16 during the cleaning process of the cup body assembly 11. Thus, it can prevent damage to the electronic devices inside the cup body shell 13 and extend the service life of the electronic devices. Moreover, the shielding member 17 has good stability in closing the air inlet and outlet, which can improve the reliability of sealing and is beneficial to further reducing the risk of water ingress.

[0047] The action of the shielding member 17 opening the air inlet and outlet 16 is completed when the cup body assembly 11 is installed on the main machine 10, without the need for additional steps, which can save user operations and improve the user experience. There is an air inlet duct inside the main machine 10, which is beneficial to the heat dissipation of relevant components inside the main machine 10. The heat dissipation duct 15 inside the cup body shell 13 is beneficial to the heat dissipation of the motor 14, so that the heat of the motor 14 can be discharged in time through the heat dissipation duct 15, avoiding heat residue and improving the heat dissipation effect of the motor 14.

[0048] The food processor in this application has the motor 14 placed on top. The motor 14 is connected below the mixing cup 12. The motor 14 can be a brushless motor 14, which is beneficial to the miniaturization of the cup body assembly 11, reducing the center of gravity of the whole machine and improving the stability of the machine operation. The motor 14 is surrounded by the cup body shell 13. By setting the air inlet, outlet and heat dissipation duct 15, during the normal operation of the machine, the inside of the cup body shell 13 and the inside of the main machine 10 are connected to achieve the heat dissipation of the motor 14 and other electronic devices.

[0049] The shielding member 17 is arranged corresponding to the air inlet and the air outlet 16. The shielding member 17 is movable relative to the cup body housing 13. The structure, moving manner, etc. of the shielding member 17 are related to the opening direction of the air inlet and the air outlet 16 and can be set according to actual requirements. In some embodiments, the air inlet and the air outlet 16 are horizontally opened. Correspondingly, the shielding member 17 has, for example, a shielding portion arranged horizontally. The shielding portion 172 can control the opening and closing of the air inlet and the air outlet 16 by means of horizontal movement, flipping, etc. In other embodiments, the air inlet and the air outlet 16 are vertically opened. Correspondingly, the shielding member 17 has, for example, a shielding portion arranged vertically, and the shielding portion can control the opening and closing of the air inlet and the air outlet 16 by moving along the vertical direction. Further, a triggering structure that cooperates with each other is provided between the shielding member 17 and the main body 10, so that it can be satisfied that during the installation process of the cup body assembly 11, the triggering structure can trigger the shielding member 17 to move to open the air inlet and the air outlet 16, and after the cup body assembly 11 is removed, the shielding member 17 can be reset to close the air inlet and the air outlet 16.

[0050] As a preferred implementation manner, a power supply board is provided in the main body 10. The power supply board includes a high-temperature area provided with an IPM module, and the air inlet duct covers the high-temperature area. By arranging the air inlet duct in the high-temperature area, centralized and rapid heat dissipation of the high-temperature area can be achieved. Under the action of the air inlet duct, not only can the aggregation of air flow be ensured to improve the uniformity of heat dissipation in the high-temperature area, but also the noise can be reduced; arranging the air inlet duct in the high-temperature area can improve the heat dissipation effect compared with the conventional air flow flowing through the power supply board in an open space, and the heat dissipation effect can be ensured for the high-temperature area with high heat dissipation requirements. Specifically, the air inlet duct can be formed by an air inlet cover arranged on the power supply board. The power supply board can be placed horizontally or vertically, and the present application does not make a limitation.

[0051] It can be understood that the power supply board also includes, for example, a low-temperature area. When the air flow flows to the low-temperature area, the air flow can flow in an open space. On the one hand, because the heat dissipation requirement of the low-temperature area is low, and on the other hand, not all modules in the low-temperature area need to dissipate heat. Such a setting is more conducive to the air flow dissipating heat from the low-temperature area, and at the same time, the air flow can flow to the high-temperature area faster and more to strengthen the heat dissipation for the high-temperature area.

[0052] The low-temperature area is distributed with, for example, a switching power supply, a control module, etc. The high-temperature area is distributed with, for example, an IPM module (i.e., an intelligent power module, which is a highly integrated power electronic device that integrates power switching devices, drive circuits, and fault detection circuits such as overvoltage, overcurrent, and overheating), a thyristor module, a rectifier module, etc. The motor 14 of the present application can adopt, for example, a variable-frequency motor, which has a wide speed regulation range, can meet the requirements of various working conditions, can improve the use performance of the food processor, and the variable-frequency motor has the advantage of low noise, which is beneficial to reducing the working noise.

[0053] The air inlet duct, for example, also covers the working area of other electronic devices to optimize the heat dissipation of other electronic devices. One end of the air inlet duct close to the cup body assembly 11 can be connected to the air inlet of the cup body shell 13 through the air flow inlet on the host 10, thereby realizing the circulation of air from the host 10 to the cup body assembly 11.

[0054] As a preferred embodiment, an air outlet duct 18 is provided in the host 10, and an air flow outlet 24 is provided in the host 10 corresponding to the air outlet 16. One end of the air outlet duct 18 is connected to the air flow outlet 24, and the other end is connected to the air outlet hole 101 on the host 10. When the cup body assembly 11 is installed on the host 10, the heat dissipation duct 15 is connected to the air outlet duct 18 through the air outlet 16 and the air flow outlet 24.

[0055] like Figure 5 As shown, by setting the air outlet duct 18, during the operation of the machine, the heat of the motor 14 can be discharged through the heat dissipation duct 15-air outlet duct 18-air outlet hole 101, which can ensure the heat dissipation efficiency. At the same time, it can avoid that part of the heat remains in the host 10 and causes the temperature of the electronic components in the host 10 to rise too high, affecting their performance and life, and can improve the heat dissipation reliability.

[0056] The motor 14 has a motor heat dissipation cavity, which is provided with a motor air inlet and a motor air outlet. The heat dissipation path of the motor 14 is: air inlet on the cup body shell 13 - motor air inlet - motor heat dissipation cavity - motor air outlet - heat dissipation duct 15 - air outlet duct 18 - air outlet hole 101. The airflow flowing into the cup body shell 13 can flow in from the gap between the cup body shell 13 and the main unit 10, or flow from the main unit 10 into the cup body shell 13.

[0057] As a preferred embodiment, the shielding member 17 can move in the vertical direction relative to the cup body shell 13. When the cup body assembly 11 is installed on the host 10, the host 10 pushes the shielding member 17 upward to open the air inlet and the air outlet 16. In this embodiment, the action of the shielding member 17 to open the air inlet and the air outlet 16 is triggered when the cup body assembly 11 is installed. The whole process is completed in one go without additional actions, which is simple and convenient for users.

[0058] As a preferred embodiment, the host 10 includes a main body shell 19 with an opening at the top and a concave main body cover 20 installed at the opening. The bottom of the main body cover 20 is provided with a first boss 21 and a second boss 22 corresponding to the air inlet and the air outlet 16 respectively. The side wall of the first boss 21 is provided with an air flow inlet 23, and the side wall of the second boss 22 is provided with an air flow outlet 24. When the cup body assembly 11 is installed on the host 10, the shielding member 17 avoids the air flow inlet 23 and the air flow outlet 24.

[0059] like Figure 2As shown, the first boss 21 and the second boss 22 are provided. On the one hand, it is beneficial for the positioning during the installation of the cup body assembly 11, so as to reduce the installation difficulty of the cup body assembly 11 and improve the efficiency. On the other hand, the air inlet 23 and the air outlet 24 are opened thereon, creating conditions for the connection of the air flow between the main machine 10 and the cup body assembly 11, so as to ensure normal heat dissipation during the operation of the machine, keep the electronic devices and the outside of the main machine 10 at a good temperature, and improve the use performance and service life of the whole machine.

[0061] By adopting the method of opening the side of the air inlet and the air outlet 16, when the cup body assembly 11 is placed alone on a liquid-containing tabletop, or when the cup body assembly 11 is cleaned, the liquid can be effectively prevented from entering the cup body housing 13. Compared with the method of directly opening holes at the bottom, the waterproof effect is better; when the cup body assembly 11 is installed, through the insertion and cooperation of the boss and the concave portion, the installation position of the cup body assembly 11 can be accurately and quickly determined, which is beneficial to the one-step installation in place and can avoid affecting the installation efficiency due to multiple adjustments of the installation position.

[0062] Specifically, the first concave portion and the second concave portion can be directly formed by the depression of the bottom wall of the cup body housing 13, or, exemplarily, as Figure 2 shown, an installation bracket 26 is provided inside the cup body housing 13. The bottom of the cup body housing 13 is provided with a first through hole 131 and a second through hole 132. The installation bracket 26 covers the upper part of the first through hole 131 and the second through hole 132. The installation bracket 26 and the first through hole 131 and the second through hole 132 respectively enclose to form the first concave portion and the second concave portion. The side wall of the installation bracket 26 is provided with an air inlet and an air outlet 16. It should be noted that in the solution with the installation bracket 26, the installation bracket 26 can be a part of the structure of the cup body housing 13.

[0063] As a preferred embodiment, a return spring 25 is provided above the shielding member 17. When the cup body assembly 11 is separated from the main machine 10, the shielding member 17 moves downward under the action of the return spring 25 to block the connection between the air inlet and the air outlet 16 and the inside of the cup body housing 13. By providing the return spring 25, it can be ensured that the shielding member 17 can quickly move to close the air inlet and the air outlet 16 after the cup body assembly 11 is removed from the main machine 10, realizing the waterproof protection of the cup body assembly 11, so that users do not have to worry about the risk of water ingress when placing or cleaning the cup body assembly 11.

[0064] As a preferred embodiment, the shielding member 17 includes a horizontally extending mounting portion 171 and a shielding portion 172 extending downward from the mounting portion 171, a mounting bracket 26 is provided in the cup body shell 13, a guide column 261 is provided on the top of the mounting bracket 26, the mounting portion 171 is provided with a guide hole 173 cooperating with the guide column 261, and the side wall of the mounting bracket 26 is provided with an air inlet and an air outlet 16, when the shielding member 17 moves upward, the shielding portion 172 opens the air inlet and the air outlet 16, and when the shielding member 17 moves downward, the shielding portion 172 blocks the air inlet and the air outlet 16.

[0065] like Figures 2 to 4 As shown, the mounting bracket 26 of the present embodiment can provide installation and movement guidance for the shielding member 17 and setting of the air inlet and the air outlet 16. It has multiple uses. The cooperation between the shielding member 17 and the mounting bracket 26 can promote the compactness of the structure inside the cup body shell 13. Moreover, the shielding member 17 has a simple structure and can be adjusted in state by vertical movement, and the operation is simple and quick.

[0066] In this embodiment, the host 10 includes a main body shell 19 and a main body cover 20. The bottom of the main body cover 20 is provided with a first boss 21 and a second boss 22. The side wall of the first boss 21 is provided with an airflow inlet 23, and the side wall of the second boss 22 is provided with an airflow outlet 24. The bottom of the cup body shell 13 is provided with a first through hole 131 and a second through hole 132. The mounting bracket 26 is arranged above the first through hole 131 and the second through hole 132. Figure 5 As shown, when the cup assembly 11 is installed on the host 10, the shielding portion 172 opens the air outlet 16, and the air outlet 16 is connected to the air outlet 24. The heat dissipation duct 15 and the air outlet duct 18 are connected through the air outlet 16 and the air outlet 24, so that the heat dissipation of the motor 14 can be achieved. Figure 4 As shown, after the cup assembly 11 is removed from the main unit 10, the shielding portion 172 moves downward to close the air outlet 16 under the action of the return spring 25, thereby achieving water ingress protection. The opening and closing control of the air inlet is the same as that of the air outlet 16, and will not be repeated here.

[0067] like Figure 2 and Figure 3 As shown, the reset spring 25 is sleeved on the guide column 261, and a stopper 262 is provided on the top of the guide column 261 to limit the reset spring 25 from escaping upward from the guide column 261. The mounting bracket 26 extends in an arc shape to cover the first through hole 131 and the second through hole 132, and the guide column 261 is provided with two corresponding to the first through hole 131 and the second through hole 132, and the corresponding guide holes 173 are also provided with two, which can improve the stability of the vertical movement of the shielding member 17.

[0068] Furthermore, a rib 174 is provided at the bottom of the installation part 171, which can penetrate through the bottom wall of the cup body housing 13. The main body 10 is provided with a protrusion 27. When the cup body assembly 11 is installed on the main body 10, the protrusion 27 pushes the rib 174 upward to move the shielding part 17 upward. Triggering the movement of the shielding part 17 by the structural cooperation between the shielding part 17 and the main body 10 has a simple structure, realizes the linkage of the shielding part 17 during the installation of the cup body assembly 11, and does not require additional actions, which can improve the user experience.

As Figure 6 shown, during the installation process of the cup body assembly 11, when the rib 174 abuts against the protrusion 27, the reaction force provided by the protrusion 27 due to the downward force of the cup body assembly 11 can push the shielding part 17 upward until the air inlet and the air outlet 16 are completely opened when the cup body assembly 11 is installed in place.

[0070] Furthermore, one end of the installation bracket 26 has an upright column 264 extending upward. The upright column 264 is hollow to form a heat dissipation air duct 15, and the upper end of the heat dissipation air duct 15 is communicated with the motor heat dissipation cavity of the motor 14.

[0071] As Figure 2 shown, the heat dissipation air duct 15 is integrally formed on the installation bracket 26, which can promote the compactness of the structure inside the cup body housing 13, is beneficial to the miniaturization of the cup body assembly 11, and compared with setting a special air duct structure inside the cup body housing 13, this embodiment has a simple structure and low manufacturing cost.
