Description
Technical Field
[0001] The invention relates to the technical field of life, and in particular to a food processor which is easy to use. Background Art
[0002] With the development of society and the improvement of living standards, people's pursuit of dietary diversity and healthy diet is constantly increasing. Therefore, various industrial food processing machines are gradually miniaturized and enter thousands of households. For example, soybean milk machines not only meet people's needs for healthy diet and nutrition, but also greatly improve people's quality of life, and are therefore loved by people.
[0003] Existing food processing machines usually include a main unit and a crushing cup with a built-in stirring element. For example, Chinese utility model patent CN208740776U discloses a new electromagnetic heating wall breaking machine, which includes a cup body and a base. The bottom of the cup body is detachably connected to the top of the base. A crushing knife assembly is provided at the bottom of the cup body, and a heating assembly is provided at the top of the base. A driving motor for driving the crushing knife assembly is provided inside the base. The transmission between the driving motor and the crushing knife requires a transmission component to be realized, that is, a first driving connecting piece is provided at the top of the motor shaft of the driving motor disclosed in the patent, and a second driving connecting piece is provided at the bottom of the crushing knife that cooperates with the first driving connecting piece. This transmission mode will cause noise between the transmission components due to transmission collision or vibration, and will cause energy loss during the transmission process, and the transmission efficiency of the whole machine is low.
[0004] For another example, Chinese utility model patent CN217720848U discloses a food processing machine with a series-excited motor, and includes a main machine and a series-excited motor arranged in the main machine, wherein the series-excited motor includes a stator and a rotor having a rotor shaft. In order to fix the series-excited motor, the patent provides a motor bracket to fix the series-excited motor in the main machine, and the motor bracket includes a front bracket and a rear bracket located at both ends of the stator core, and two relatively arranged isolation brackets are respectively provided on the front bracket and the rear bracket.
[0005] Another food processing machine, such as Chinese utility model patent CN111493695A, discloses a wall breaking machine, which includes a machine base and a machine body, a receiving cavity is arranged on the machine base, the machine body is detachably arranged on the receiving cavity, a first electrical connector is arranged at the bottom of the receiving cavity, the machine body includes a cup cover, a cup body, a cup base, a motor, a cutter, a heating plate assembly and a second electrical connector, that is, the motor is directly installed in the cup body assembly so that it can be removed from the main machine together with the cup body assembly. If the series-excited motor in CN217720848U is applied In this solution, the overall weight and volume of the series-excited motor will result in a large weight and space occupied by the cup body assembly. It will be very difficult for users to pick up the entire cup body assembly, and it will be very inconvenient to store it. In addition, the motor bracket is fixed to the main unit through the front bracket and the rear bracket, which further increases the weight of the entire machine and causes the axial height of the entire machine to be too high, thereby increasing the center of gravity of the entire machine, causing the food processor to shake or even topple over due to the high center of gravity when processing ingredients, seriously affecting the consumer experience. Summary of the invention
[0006] The purpose of the present invention is to provide an easy-to-use food processor to solve the problems of low transmission efficiency and noise caused by the motor of the existing food processor being connected to the stirring element through a connecting piece, and the motor being too large causing the overall weight of the whole machine to be too large and difficult to hold.
[0007] To achieve the above-mentioned purpose, the present invention provides an easy-to-use food processing machine, including a main machine and a grinding cup with a built-in stirring member, a heating plate is provided below the grinding cup, and a brushless motor is also provided below the heating plate, the brushless motor includes a motor body and a motor lower shell provided on the outer side of the bottom of the motor body, the motor lower shell is fixedly connected to the heating plate to fix the motor body between the motor lower shell and the heating plate, and the top end of the motor shaft of the motor body is fixedly connected to the stirring member.
[0008] The present application arranges a heating plate under the grinding cup, so that when the user needs to heat the ingredients in the grinding cup when using the food processor to process ingredients, the ingredients in the grinding cup can be heated by controlling the heating plate to generate heat, thereby improving the temperature and taste of the output ingredients. At the same time, the heated ingredients are easier to stir and process, which helps to improve the processing efficiency of the ingredients and meet the needs of users.
[0009] At the same time, a brushless motor is also provided under the heating plate. With the characteristics of the brushless motor, when the user uses the food processor to process food, the noise of the motor rotation is lower, achieving the effect of noise reduction. At the same time, the brushless motor can realize variable frequency control, so that the food processor can control the brushless motor to output different speeds according to different food ingredients and processing processes, which can make the food processing effect better and more complete, improve the taste of the food output, and the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the whole machine, reduce the space occupied by the food processor, and facilitate user storage. Moreover, compared with the brushed motor of the traditional solution, with the same output performance, due to the high power density of the brushless motor, the weight of the motor can be reduced by 30%, and even the use of high-grade rare earth magnets can reduce the weight by more than 40%, thereby effectively reducing the weight of the whole machine, facilitating the handling operation, and facilitating the user to move and clean the food processor, thus improving the user experience.
[0010] In addition, the top end of the motor shaft of the motor body is fixedly connected to the stirring element, so that the motor shaft can be directly connected to the stirring element and thus directly drive the stirring element, eliminating the need for additional transmission components such as couplings, etc., which not only improves the transmission efficiency of the motor, but also reduces the noise generated by transmission collision or vibration between components, and reduces the number of parts of the whole machine, making the internal structure more compact, and further reducing the weight of the whole machine, making it easier for users to hold and operate.
[0011] In addition, the lower shell of the motor is fixedly connected to the heating plate to fix the motor body between the lower shell of the motor and the heating plate. On the one hand, it eliminates the need to provide an outer shell outside the motor body and then fix the entire motor in the base through a motor bracket. The number of parts of the entire motor and the entire machine is greatly simplified, which helps to further improve the compactness of the internal structure of the whole machine and further reduce the overall weight. On the other hand, compared with the traditional method of fixing the motor in the base through an upper motor bracket and a lower motor bracket, the entire motor body and the heating plate can be fixed by only one lower shell of the motor, further reducing the number of parts and at the same time compressing the axial height of the integrated assembly of the brushless motor and the heating plate, so that the axial height of the whole machine is lower and thinner, further reducing the occupied space of the food processor, and at the same time reducing the center of gravity height of the whole machine, making the food processor more stable when working.
[0012] In a preferred implementation of an easy-to-use food processor, the motor body includes a stator assembly and a rotor assembly rotatably disposed in the stator assembly, and the motor lower shell includes a bearing portion abutting against the bottom end of the stator assembly and a connecting portion connected to the heating plate.
[0013] By configuring the motor lower shell to include a bearing portion abutting against the bottom end of the stator assembly and a connecting portion connected to the heating plate, the entire motor body is clamped and fixed between the bearing portion and the heating plate, which helps to improve the stability of the motor body, and the motor lower shell does not need to limit and wrap the side wall of the stator assembly, which not only further simplifies the structure of the motor lower shell and reduces its occupied space and weight, but also increases the heat dissipation area of the motor body and the heat dissipation effect of the brushless motor, thereby avoiding the situation where the motor lower shell fully wraps the stator assembly, resulting in poor heat dissipation effect of the brushless motor, causing obvious temperature rise of the brushless motor, and serious heat aging of internal components, which helps to extend the service life of components such as the brushless motor.
[0014] In a preferred implementation of an easy-to-use food processor, the stator assembly includes a stator coil and a stator shell, the outer wall of the stator shell is provided with a fixing portion aligned with the connecting portion, and the food processor also includes a connecting part, which passes through the connecting portion and the fixing portion in sequence and is fixed to the heating plate.
[0015] By providing a fixing portion aligned with the connecting portion on the outer wall of the stator shell, and the food processing machine also includes a connecting piece, the connecting piece passes through the connecting portion and the fixing portion in sequence and is fixed to the heating plate, so that the three components are fixedly connected after the connecting piece passes through the connecting portion and the fixing portion and is fixed to the heating plate. On the one hand, the connecting piece can achieve radial and circumferential limitation of the stator assembly after passing through the fixing portion, improve the position stability of the stator assembly and the entire motor body, and avoid the situation where the stator assembly of the brushless motor moves circumferentially or radially during operation, resulting in unstable rotation or even inability to work; on the other hand, one connecting piece can fix the stator shell, the motor body and the heating plate, which helps to improve the coaxiality of the three, thereby ensuring the stability of the rotation of the brushless motor, and can improve assembly efficiency and shorten assembly time.
[0016] In a preferred implementation of a food processor that is easy to use, the motor body includes a stator assembly and a rotor assembly rotatably disposed in the stator assembly, and the motor lower shell is a plastic sealing member sealed and wrapped around the outside of the stator assembly.
[0017] By setting the lower shell of the motor as a plastic sealing part that is sealed and wrapped around the outside of the stator assembly, not only can the motor body be fixed by connecting the lower shell of the motor with the heating plate, but the stator assembly can also be sealed, so that the stator assembly is not exposed. At the same time, the rotor assembly has no live parts, so that even if the user sprays a small amount of water on the brushless motor when cleaning the whole machine, it will not cause internal insulation failure of the brushless motor, thereby improving the waterproofness of the brushless motor, protecting the brushless motor, improving product and user safety, and helping to extend the service life of the brushless motor.
[0018] In a preferred implementation of a convenient food processor, the stator coil in the stator assembly is connected to the power line via a terminal, the plastic package is provided with a through hole for the terminal to pass through, and a sealing member is provided between the through hole and the terminal.
[0019] By providing a through hole for the terminal to pass through in the plastic package and a sealing member between the through hole and the terminal, a seal is achieved between the through hole and the terminal, thereby preventing external cleaning water from flowing into the inside of the motor body, especially the stator coil, through the gap between the through hole and the terminal when the user cleans the whole machine, thereby preventing the brushless motor from short-circuiting or even being damaged. This further improves the waterproof performance of the brushless motor and the protection of the brushless motor.
[0020] In a preferred implementation of an easy-to-use food processor, the food processor also includes a base connected to the bottom of the grinding cup and detachably arranged on the main unit, the main unit is provided with a control module and a lower coupler electrically connected to the control module, and the base is also provided with an upper coupler electrically connected to the brushless motor and the heating plate and coupleable to the lower coupler.
[0021] By setting a control module in the main unit, the user can control the operation of the whole machine through the control module, thereby realizing the control of the brushless motor and the heating plate to meet the user's use needs. At the same time, compared with the traditional method of installing the control module on the base, the weight of the grinding cup and the base is further reduced, making it more convenient for the user to take the grinding cup, and when the user cleans the grinding cup, the cleaning water will not spill on the control module, causing the control module and other electrical components to be damp, short-circuited or even damaged, thus realizing the protection of the control module and helping to extend the service life of the whole machine.
[0022] In a preferred implementation of the easy-to-use food processor, the main body and the base are further provided with a heat dissipation channel that is interconnected, and the food processor further includes a fan disposed in the heat dissipation channel.
[0023] By providing mutually interconnected heat dissipation channels between the main unit and the base, and the food processor also including a fan arranged in the heat dissipation channel, the fan can drive the air flow in the heat dissipation channel during the use of the food processor, so that the cold air from the outside can pass into the heat dissipation channel, thereby achieving heat dissipation of the components in the heat dissipation channel, avoiding the situation where the internal components have poor heat dissipation effect and the temperature is too high for a long time, causing serious aging, which helps to extend the service life of each component.
[0024] Moreover, the heat dissipation channel in the main unit is interconnected with the heat dissipation channel in the base, so that the heat dissipation efficiency is greatly improved. Preferably, only one fan can be arranged in the heat dissipation channel to realize the flow of air in the heat dissipation channel and realize the overall heat dissipation of the entire food processor. Compared with the method of arranging fans in both the base and the main unit, the number of parts is greatly simplified. One fan can realize the heat dissipation of the whole machine, which helps to further reduce the weight of the whole machine and is convenient for users to take and store.
[0025] In a preferred implementation of a convenient food processor, the fan is located in the base and is drivingly connected to the bottom end of the motor shaft; or,
[0026] The fan is located in the main engine, the bottom end of the motor shaft is connected to an upper coupling, and the fan is provided with a lower coupling that can be connected to the upper coupling; or,
[0027] The fan is located in the main unit, and a driving motor for driving the fan to rotate is also arranged in the main unit.
[0028] By arranging the fan to be located inside the base and connected to the bottom end of the motor shaft by transmission, the brushless motor can synchronously drive the fan to rotate when working, thereby realizing the flow of air in the entire heat dissipation channel and achieving heat dissipation of various components. At the same time, the motor shaft directly drives the fan, eliminating the structure of a separate transmission component, which helps to improve the transmission efficiency of the fan, while further reducing the number of components and reducing the weight of the entire machine.
[0029] By arranging the fan to be located inside the main machine, the bottom end of the motor shaft is connected to an upper coupling, and the fan is provided with a lower coupling that can be connected to the upper coupling, so that when the crushing cup and the base are installed on the main machine, the upper coupling and the lower coupling cooperate to achieve a transmission connection, and the fan is arranged inside the main machine, which further reduces the weight of the crushing cup and the base, thereby further facilitating the user to take the crushing cup and the base.
[0030] By arranging the fan to be located inside the main unit, and also providing a driving motor inside the main unit to drive the fan to rotate, the fan is driven by a separate driving motor, eliminating the need for transmission components to achieve a transmission connection between the brushless motor and the fan, further simplifying the components inside the grinding cup and the base, and further reducing the weight of the grinding cup and the base, making it easier to take the grinding cup and the base.
[0031] In a preferred implementation of a food processor that is easy to use, the heat dissipation channel has an air inlet and an air outlet, and the control module is located on a side close to the air inlet so that the air flow passes through the control module first and then passes through the brushless motor.
[0032] By setting the heat dissipation channel with an air inlet and an air outlet, and the control module being located on the side close to the air inlet, the airflow passes through the control module first and then through the brushless motor. This allows the external cold air to first dissipate heat for the control module after entering the heat dissipation channel. This helps to improve the heat dissipation effect of the airflow on the control module, reduce the impact of excessive temperature on the control module, and reduce the risk of severe aging of electrical components in the control module due to long-term high temperature. It avoids the airflow passing through other components such as a brushless motor and then through the control module, causing the airflow temperature to rise, resulting in poor heat dissipation effect of the airflow on the control module, resulting in the control module being easily damaged due to excessive temperature.
[0033] In a preferred implementation of a food processor that is easy to use, the grinding cup is a vertically through-structure, and the heating plate abuts against the bottom end of the grinding cup to enclose the grinding cup to form a grinding chamber.
[0034] By setting the grinding cup as a top-to-bottom through structure, and the heating plate abutting the bottom end of the grinding cup to enclose the grinding cup to form a grinding chamber, the setting of the bottom wall of the grinding cup is eliminated, which not only helps to reduce the demolding amount of the grinding cup, and thus reduce the weight of the grinding cup, thereby further reducing the weight of the whole machine and facilitating the handling of the whole machine, but also enables the heat generated by the heating plate to be directly transferred to the food, which helps to improve the thermal conductivity effect and improve the heating efficiency.

DETAILED DESCRIPTION
[0045] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.
[0046] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0047] like Figures 1 to 6 As shown, the present invention provides an easy-to-use food processing machine, including a main body 1 with a grinding cup 2 having a built-in stirring member 5, a heating plate 4 is provided below the grinding cup 2, and a brushless motor 6 is also provided below the heating plate 4, the brushless motor 6 includes a motor body 61 and a motor lower shell 62 provided on the outer side of the bottom of the motor body 61, the motor lower shell 62 is fixedly connected to the heating plate 4 to fix the motor body 61 between the motor lower shell 62 and the heating plate 4, and the top end of the motor shaft of the motor body 61 is fixedly connected to the stirring member 5.
[0048] The present application arranges a heating plate 4 under the grinding cup 2, so that when the user needs to heat the food in the grinding cup 2 when using the food processor to process food, the food in the grinding cup 2 can be heated by controlling the heating plate 4 to generate heat, thereby improving the temperature and taste of the output food. At the same time, the heated food is easier to stir and process, which helps to improve the processing efficiency of the food and meet the user's needs.
[0049] At the same time, a brushless motor 6 is also provided under the heating plate 4. With the characteristics of the brushless motor 6, when the user uses the food processor to process food, the noise of the motor rotation is lower, achieving the effect of noise reduction. At the same time, the brushless motor 6 can realize variable frequency control, so that the food processor can control the brushless motor 6 to output different speeds according to different food materials and processing processes, which can make the processing effect of food materials better and more complete, improve the taste of food products, and the brushless motor 6 occupies a small space, which helps to improve the compactness of the internal structure of the whole machine, reduce the space occupied by the food processor, and facilitate user storage. Moreover, compared with the brushed motor of the traditional solution, with the same output performance, due to the high power density of the brushless motor 6, the weight of the motor can be reduced by 30%, and even the use of high-grade rare earth magnets can reduce the weight by more than 40%, thereby effectively reducing the weight of the whole machine, facilitating the handling operation, and facilitating the user to move and clean the food processor, thereby improving the user experience.
[0050] And the top end of the motor shaft of the motor body 61 is fixedly connected to the stirring member 5, so that the motor shaft can be directly connected to the stirring member 5 and then directly drive the stirring member 5, eliminating the need for additional transmission components such as couplings, etc., which can not only improve the transmission efficiency of the motor, but also reduce the noise generated by transmission collision or vibration between the components, and reduce the number of parts of the whole machine, making the internal structure more compact, and further reducing the weight of the whole machine, making it convenient for users to take and operate. It should be noted that the present application does not specifically limit the relative relationship between the brushless motor 6 and the crushing cup 2. It can be that the brushless motor 6 is arranged laterally relative to the crushing cup 2 in the axial direction, and the transmission of the motor shaft is realized through transmission components such as gears, etc., which will not be repeated here.
[0051] In addition, the motor lower shell 62 is fixedly connected to the heating plate 4 to fix the motor body 61 between the motor lower shell 62 and the heating plate 4. On the one hand, it eliminates the need to dispose a shell outside the motor body 61 and then fix the entire motor in the base 3 through a motor bracket, which greatly simplifies the number of parts of the entire motor and the entire machine, and helps to further improve the compactness of the internal structure of the whole machine and further reduce the overall weight; on the other hand, compared with the traditional method of fixing the motor in the base 3 by an upper motor bracket and a lower motor bracket, the entire motor body 61 and the heating plate 4 can be fixed by only one motor lower shell 62, which further reduces the number of parts and compresses the axial height of the integrated assembly of the brushless motor 6 and the heating plate 4, so that the axial height of the whole machine is lower and thinner, further reducing the occupied space of the food processor, and at the same time reducing the center of gravity height of the whole machine, making the food processor more stable when working.
[0052] It should be noted that the present application does not specifically limit the structure of the motor lower housing 62, which may be any one of the following embodiments:
[0053] Example 1: Figure 3 , Figure 4 As shown, the motor body 61 includes a stator assembly 611 and a rotor assembly 612 rotatably disposed in the stator assembly 611 , and the motor lower shell 62 includes a bearing portion 621 abutting against the bottom end of the stator assembly 611 and a connecting portion 622 connected to the heating plate 4 .
[0054] By configuring the motor lower shell 62 to include a bearing portion 621 abutting against the bottom end of the stator assembly 611 and a connecting portion 622 connected to the heating plate 4, the entire motor body 61 is clamped and fixed between the bearing portion 621 and the heating plate 4, which helps to improve the stability of the motor body 61, and the motor lower shell 62 does not need to limit the side wall of the stator assembly 611. This not only further simplifies the structure of the motor lower shell 62 and reduces its occupied space and weight, but also increases the heat dissipation area of the motor body 61 and the heat dissipation effect of the brushless motor 6, and avoids the situation where the motor lower shell 62 fully wraps the stator assembly 611, resulting in poor heat dissipation effect of the brushless motor 6, causing a significant temperature rise of the brushless motor 6, and severe heat aging of the internal components, which helps to extend the service life of components such as the brushless motor 6.
[0055] Furthermore, if Figure 3 , Figure 4 As shown, the stator assembly 611 includes a stator coil and a stator shell, and the outer wall of the stator shell is provided with a fixing portion 6111 aligned with the connecting portion 622. The food processor also includes a connecting piece, which passes through the connecting portion 622 and the fixing portion 6111 in sequence and is fixed to the heating plate 4.
[0056] By providing a fixing portion 6111 aligned with the connecting portion 622 on the outer wall of the stator shell, and the food processing machine also includes a connecting piece, the connecting piece passes through the connecting portion 622 and the fixing portion 6111 in sequence and is fixed to the heating plate 4, so that the three components are fixedly connected after the connecting piece passes through the connecting portion 622 and the fixing portion 6111 and is fixed to the heating plate 4. On the one hand, after the connecting piece passes through the fixing portion 6111, the radial and circumferential limiting of the stator assembly 611 can be achieved, thereby improving the position stability of the stator assembly 611 and the entire motor body 61, and avoiding the circumferential or radial movement of the stator assembly 611 during operation of the brushless motor 6, resulting in unstable rotation or even failure to work; on the other hand, one connecting piece can fix the stator shell, the motor body 61 and the heating plate 4, which helps to improve the coaxiality of the three, thereby ensuring the rotation stability of the brushless motor 6, and can improve the assembly efficiency and shorten the assembly time.
[0057] Specifically, Figure 3 , Figure 4As shown, the connecting portion 622 is a protrusion arranged on the outer periphery of the bearing portion 621, and a through hole is arranged on the protrusion. At the same time, the fixing portion 6111 is a protrusion arranged on the outer wall of the stator shell and extending axially, and a through hole is arranged in the protrusion extending up and down. The heating plate 4 is provided with a downwardly extending mounting column, and a threaded hole is arranged in the mounting column. The connecting piece is preferably a bolt, which passes through the through hole on the protrusion and the through hole on the protrusion in turn and is locked in the threaded hole, so as to realize the fixed connection between the motor lower shell 62, the motor body 61 and the heating plate 4.
[0058] Example 2: Figure 5 , Figure 6 As shown, in this embodiment, the motor body 61 includes a stator assembly 611 and a rotor assembly 612 rotatably disposed in the stator assembly 611 , and the motor lower shell 62 is a plastic package sealed and wrapped around the outside of the stator assembly 611 .
[0059] By setting the motor lower shell 62 as a plastic sealing part that is sealed and wrapped around the outside of the stator assembly 611, not only can the motor body 61 be fixed by connecting the motor lower shell 62 with the heating plate 4, but the stator assembly 611 can also be sealed, so that the stator assembly 611 is not exposed, and the rotor assembly 612 has no live parts, so that the user can spray a small amount of water on the brushless motor 6 when cleaning the whole machine without causing internal insulation failure of the brushless motor 6, thereby improving the waterproofness of the brushless motor 6, protecting the brushless motor 6, improving product and user safety, and helping to extend the service life of the brushless motor 6.
[0060] Furthermore, if Figure 5 , Figure 6 As shown, the stator coil in the stator assembly 611 is connected to the power line through the terminal 6112 , and the plastic package is provided with a through hole 623 for the terminal 6112 to pass through, and a sealing member is provided between the through hole 623 and the terminal 6112 .
[0061] By providing a through hole 623 for the terminal 6112 to pass through in the plastic package, and providing a sealing member between the through hole 623 and the terminal 6112, a seal is achieved between the through hole 623 and the terminal 6112, thereby preventing external cleaning water from flowing into the interior of the motor body 61, especially the stator coil, through the gap between the through hole 623 and the terminal 6112 when the user cleans the entire machine, thereby preventing the brushless motor 6 from short-circuiting or even being damaged. This further improves the waterproof performance of the brushless motor 6 and the protection of the brushless motor 6.
[0062] It should be noted that the present application does not specifically limit the structure of the food processor. Figure 7 As shown, it can be that a mounting cavity is provided in the main unit 1, and the grinding cup 2, the heating plate 4 and the brushless motor 6 are all accommodated in the mounting cavity. It can also be used as a preferred embodiment of the present application, such as Figure 2 As shown, the food processor also includes a base 3 connected to the bottom of the grinding cup 2 and detachably arranged on the main unit 1. The main unit 1 is provided with a control module 7 and a lower coupler electrically connected to the control module 7. The base 3 is also provided with an upper coupler electrically connected to the brushless motor 6 and the heating plate 4 and coupleable to the lower coupler.
[0063] By providing a control module 7 in the main unit 1, the user can control the operation of the whole machine through the control module 7, thereby realizing the control of the brushless motor 6 and the heating plate 4, and meeting the user's use needs. At the same time, compared with the traditional method of installing the control module 7 and the like on the base 3, the weight of the grinding cup 2 and the base 3 is further reduced, making it more convenient for the user to take the grinding cup 2, and when the user cleans the grinding cup 2, the cleaning water will not be spilled on the control module 7, causing the control module 7 and other electrical components to be damp, short-circuited or even damaged, thereby realizing the protection of the control module 7 and helping to extend the service life of the whole machine.
[0064] Furthermore, if Figure 2 As shown, the main unit 1 and the base 3 are also provided with a heat dissipation channel which is interconnected, and the food processor also includes a fan 8 which is arranged in the heat dissipation channel.
[0065] By providing mutually connected heat dissipation channels between the main unit 1 and the base 3, and the food processor further comprising a fan 8 arranged in the heat dissipation channel, when the food processor is in use, the fan 8 can drive the air flow in the heat dissipation channel, so that the cold air from the outside passes into the heat dissipation channel, thereby achieving heat dissipation of the components in the heat dissipation channel, avoiding the situation where the internal components have poor heat dissipation effect and the temperature is too high for a long time, causing serious aging, which helps to extend the service life of each component.
[0066] Moreover, the heat dissipation channel in the main unit 1 is interconnected with the heat dissipation channel in the base 3, so that the heat dissipation efficiency is greatly improved. Preferably, only one fan 8 can be arranged in the heat dissipation channel to realize the flow of air in the heat dissipation channel and realize the overall heat dissipation of the entire food processor. Compared with the method of arranging fans 8 in both the base 3 and the main unit 1, the number of parts is greatly simplified. One fan 8 can realize the heat dissipation of the whole machine, which helps to further reduce the weight of the whole machine and is convenient for users to take and store.
[0067] It should be noted that the present application does not specifically limit the configuration of the fan 8, which may be any one of the following embodiments:
[0068] Example 1: Figure 2 As shown, in this embodiment, the fan 8 is located in the base 3 and is drivingly connected to the bottom end of the motor shaft.
[0069] By arranging the fan 8 to be located inside the base 3 and connected to the bottom end of the motor shaft by transmission, the brushless motor 6 can synchronously drive the fan 8 to rotate when working, thereby realizing the flow of air in the entire heat dissipation channel and achieving heat dissipation of various components. At the same time, the motor shaft directly drives the fan 8, eliminating the structure of a separate transmission component, which helps to improve the transmission efficiency of the fan 8, while further reducing the number of components and reducing the weight of the entire machine.
[0070] Embodiment 2: In this embodiment, the fan 8 is located in the main unit 1, the bottom end of the motor shaft is connected with an upper coupling, and the fan 8 is provided with a lower coupling that can be connected to the upper coupling.
[0071] By arranging the fan 8 to be located inside the main unit 1, the bottom end of the motor shaft is connected to an upper coupling, and the fan 8 is provided with a lower coupling that can be connected to the upper coupling, so that when the crushing cup 2 and the base 3 are installed on the main unit 1, the upper coupling and the lower coupling are transmission-coordinated to achieve transmission connection, and the fan 8 is arranged inside the main unit 1, which further reduces the weight of the crushing cup 2 and the base 3, thereby further facilitating the user to take the crushing cup 2 and the base 3.
[0072] Embodiment 3: In this embodiment, the fan 8 is located in the main unit 1, and a driving motor for driving the fan 8 to rotate is also provided in the main unit 1.
[0073] By arranging the fan 8 to be located inside the main unit 1, and also providing a driving motor inside the main unit 1 to drive the fan 8 to rotate, the fan 8 is driven by a separate driving motor, eliminating the need for transmission components to realize the transmission connection between the brushless motor 6 and the fan 8, further simplifying the components inside the grinding cup 2 and the base 3, and further reducing the weight of the grinding cup 2 and the base 3, making it easier to take the grinding cup 2 and the base 3.
[0074] As a preferred embodiment of this implementation, the heat dissipation channel has an air inlet and an air outlet, and the control module 7 is located on the side close to the air inlet so that the airflow passes through the control module 7 first and then passes through the brushless motor 6.
[0075] By providing the heat dissipation channel with an air inlet and an air outlet, and the control module 7 is located on the side close to the air inlet, so that the airflow passes through the control module 7 first and then passes through the brushless motor 6, the external cold air can first dissipate heat to the control module 7 after entering the heat dissipation channel, which helps to improve the heat dissipation effect of the airflow on the control module 7, can reduce the impact of excessive temperature on the control module 7, and reduce the risk of serious aging of electrical components in the control module 7 due to long-term high temperature, and avoid the airflow passing through other components such as the brushless motor 6 and then passing through the control module 7, resulting in the airflow passing through the control module 7 after the airflow temperature rises, resulting in poor heat dissipation effect of the airflow on the control module 7, so that the control module 7 is easily damaged due to excessive temperature.
[0076] It should be noted that the heat dissipation channel in the present application is not limited to the above-mentioned setting, and it can also be a heat dissipation channel separately set in the host 1 and the base 3, and a fan 8 connected to the motor shaft of the brushless motor 6 is set in the base 3, and a drive motor and a fan 8 connected to the drive motor are set in the host 1, so as to achieve separate heat dissipation of the host 1 and the whole machine and improve the heat dissipation efficiency. At the same time, it is saved to open a through hole in the host 1 to connect with the whole machine, thereby improving the sealing and waterproofness of the host 1, making it convenient for users to clean the host 1 and improving the user experience.
[0077] As a preferred implementation of the present application, Figure 2 As shown, the grinding cup 2 is a through structure from top to bottom, and the heating plate 4 abuts against the bottom end of the grinding cup 2 to enclose the grinding cup 2 to form a grinding chamber.
[0078] By setting the grinding cup 2 as a top-to-bottom through structure, and the heating plate 4 abutting against the bottom end of the grinding cup 2 to enclose the grinding cup 2 to form a grinding chamber, the setting of the bottom wall of the grinding cup 2 is eliminated, which not only helps to reduce the demolding amount of the grinding cup 2, and then reduces the weight of the grinding cup 2, thereby further reducing the weight of the whole machine and facilitating the taking of the whole machine, but also enables the heat generated by the heating plate 4 to be directly transferred to the food, which helps to improve the thermal conductivity effect and improve the heating efficiency.
