Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchen appliances, in particular to a food processing machine. Background Art
[0002] The cup assembly of an existing food processor consists of an axially through-the-cup body and a heating plate located at the bottom opening of the cup body. The heating plate heats the material in the cup body during operation, processing the food. Because the heating plate and the cup body form a processing chamber, if the heating plate is designed with a raised profile, it will occupy a portion of the processing chamber when embedded in the cup body, necessitating a larger cup body to maintain this capacity, leading to increased costs.
[0003] For example, patent CN209712658U discloses a food processor in which the electric heating element at the bottom of the cup body is convexly arranged relative to the cup body. When a certain processing capacity is required, the size of the cup body needs to be increased, and the cup body uses more materials, resulting in increased costs.
[0004] Furthermore, the above-mentioned food processor adopts a solution in which the motor is placed on top. The motor is provided below the electric heating element. The electric heating element is provided with a accommodating cavity with an opening facing downward, and the upper end of the motor is wrapped inside the accommodating cavity. On the one hand, the space of the accommodating cavity is limited. When the radial dimension of the motor is large, a accommodating cavity with a larger radial dimension needs to be used to match it, which will cause the volume of the electric heating element and the cup body to increase, which is not conducive to the miniaturization of the cup body assembly; on the other hand, the accommodating cavity wraps the motor, which will affect the heat dissipation of the motor under the limited wrapping space, resulting in poor heat dissipation effect of the motor.
[0005] Therefore, for models with upper motors, how to optimize the shape of the heating plate to achieve low cost while meeting processing requirements and improving the installation and heat dissipation of the motor remains to be solved. Utility Model Content
[0006] The utility model provides a food processing machine, aiming to solve the problems of high cup material cost, small available motor installation space and poor motor heat dissipation effect caused by the use of a heating plate convex relative to a cup body in the prior art.
[0007] The utility model discloses a food processor, comprising a cup body assembly with a built-in motor assembly, the cup body assembly comprising a stirring cup with an opening at the bottom, a heating plate arranged at the opening, and a cup body bracket, a stirring blade assembly driven by the motor assembly is provided in the stirring cup, the heating plate is fixed by clamping the stirring cup and the cup body bracket, the heating plate is arranged to be convex relative to the stirring cup, an auxiliary crushing cavity is formed on the inner side of the heating plate, a motor assembly is fixed to the outer side of the heating plate corresponding to the auxiliary crushing cavity, the heating plate comprises a heating plate main body and a heating tube integrally die-cast on the heating plate main body, the upper end of the motor shaft of the motor assembly passes through the heating plate, extends into the stirring cup, and is fixed to the stirring blade assembly.
[0008] The food processing machine of the present invention also has the following additional technical features:
[0009] The bottom side of the heating plate corresponding to the auxiliary crushing chamber is provided with a mounting platform, and the motor assembly is flexibly suspended on the mounting platform.
[0010] The mounting platform is provided with a screw column for fixing the motor assembly, and the mounting platform is also fixed with a temperature controller for detecting the temperature of the heating disk on the radial inner side of the screw column.
[0011] The heating plate includes a base and a surrounding edge bent upward from the edge of the base, the space from the top of the surrounding edge to the base forms an auxiliary crushing chamber, and the space from the bottom end of the stirring cup to the top end of the stirring cup forms a main crushing chamber connected to the auxiliary crushing chamber.
[0012] The heating plate comprises a bottom plate and a boss protruding upward from the center of the bottom plate, and the stirring blade assembly is suspended above the boss.
[0013] An accommodating cavity is formed on the outer side of the boss, and an inner sealing assembly and a bearing that match the motor shaft are sequentially arranged in the accommodating cavity in a direction away from the stirring blade assembly.
[0014] The motor assembly includes a motor body and a motor lower cover, and the heating plate and the motor lower cover jointly surround the motor body.
[0015] The motor assembly includes a motor, which is a brushless motor.
[0016] A sealing ring is sleeved on the edge of the heating plate, and the sealing ring is clamped by the stirring cup and the cup body bracket.
[0017] The top end of the boss is arranged higher than the bottom end of the mixing cup. The mixing blade assembly includes a horizontally extending base. The distance between the base and the boss is 5-20 mm.
[0018] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0019] 1. Compared with the convex heating plate in the prior art, the present application adopts a heating plate shape that is convex relative to the cup body. The concave space of the heating plate itself can constitute a part of the crushing space. When a certain processing chamber capacity is required, it is conducive to using a smaller cup body, thereby reducing costs. Furthermore, the heating plate shape of the present application allows the outer side of the heating plate to have a relatively open space. When installing the motor assembly, there is no need to confine the motor assembly to a small space. It can accommodate the installation of motor assemblies of more sizes. Moreover, when the motor assembly is free from being wrapped, the heat dissipation efficiency of the motor assembly is higher, so that the motor assembly maintains a suitable temperature and avoids excessive temperature affecting its performance and life. An auxiliary crushing chamber is formed on the inner side of the heating plate, which can increase the contact area between the material and the heating plate. The material is easier to crush after being heated and softened in the auxiliary crushing chamber, which can improve the crushing effect.
[0020] 2. The existing upward convex heating plate is provided with a accommodating cavity with an opening facing downwards, and the upper end of the motor needs to be accommodated in the accommodating cavity. The limited space of the accommodating cavity results in limited space for the motor installation, which is not conducive to the installation of larger-sized motors. In order to solve this problem, the present application forms an open mounting platform on the bottom side of the heating plate, which is not limited to wrapping the motor assembly in a narrow space. The motor assembly is hoisted on the mounting platform, which can not only meet the installation requirements of motor assemblies of more sizes, but also a gap is usually formed between the motor assembly and the mounting platform, which is conducive to the heat dissipation of the motor assembly and can meet the heat dissipation requirements of the motor assembly. When the motor assembly is flexibly installed, the vibration of the motor assembly can be prevented from being transmitted to the heating plate to affect the firmness of the heating plate installation, and the cup assembly can be made to run more smoothly with less working noise.
[0021] 3. Generally, a thermostat is provided near the heating disk to detect the temperature of the heating disk. When the temperature of the heating disk exceeds a certain threshold, the heating disk is shut down to provide safety protection. The space of the accommodating cavity of the above-mentioned existing heating disk is limited. In order to realize the installation of multiple components such as the thermostat and the motor, a heating disk with a larger radial size is required, resulting in a larger volume of the heating disk and the cup body, which is not conducive to the miniaturization and lightness of the machine. Under the premise of forming an open installation platform, the present application has sufficient space to install the motor assembly and the thermostat, and the space utilization rate is improved. Screw columns are provided on the installation platform to fix the motor assembly, which is not only simple in structure but also occupies less space, so that there is more space in other areas of the installation platform to arrange the thermostat, which effectively solves the installation problem of multiple components on the heating disk and promotes the compactness of the component arrangement.
[0022] 4. This application utilizes a blender cup and heating plate to form a primary and secondary grinding chamber from top to bottom. While maintaining a given cup size, the overall grinding space is expanded, enabling the production of larger beverages while also enhancing the grinding efficiency. The material tumbles between the secondary and primary grinding chambers, creating a more turbulent flow and increasing the contact area between the material and the heating plate. After being heated and softened in the secondary grinding chamber, the material becomes easier to grind, resulting in a more effective grinding process.
[0023] 5. Usually, the blade of the stirring blade assembly is located at a certain height above the bottom of the heating plate. In order to prevent the stirring blade assembly from shaking and causing unstable operation or even causing the blade to get stuck when it is protruding too high, the heating plate includes a chassis and a boss protruding upward from the center of the chassis. The stirring blade assembly is suspended above the boss. By setting the boss, it can support and limit the motor shaft, thereby preventing the upper end of the motor shaft from shaking and affecting the stability of the stirring blade assembly.
[0024] Furthermore, a receiving cavity is formed on the outer side of the boss, on which an internal sealing assembly and a bearing that cooperate with the motor shaft can be installed, thereby preventing the liquid in the crushing cavity from flowing through the matching gap between the boss and the motor shaft to the motor assembly below, thereby damaging the structure of the motor assembly. The setting of the bearing ensures the stability of the operation of the stirring blade assembly driven by the motor shaft.
[0025] 6. In order to simplify the composition of the motor assembly, the motor assembly includes a motor body and a motor lower cover. The heating plate and the motor lower cover jointly surround the motor body, so the motor upper cover can be omitted. The heating plate can be reused as the motor upper cover, which can simplify the configuration of the motor assembly and help make the motor assembly and the heating plate more compact.
[0026] 7. The motor of the present application may be a brushless motor. On the one hand, the brushless motor is small in size and light in weight, which can reduce the installation burden of the heating plate and is beneficial to the stable operation of the cup body assembly. On the other hand, the flattening of the brushless motor can reduce the overall axial size of the cup body assembly, which is beneficial to the miniaturization and lightness of the entire machine.
[0027] 8. In order to prevent liquid from flowing into the cup body shell below from the matching gap between the heating plate and the stirring cup and damaging the internal electrical components, and to prevent materials or residues from being trapped in the matching gap between the heating plate and the stirring cup and causing odor, a sealing ring is provided on the edge of the heating plate, and the stirring cup and the cup body bracket clamp the sealing ring. In addition to providing sealing, the sealing ring also facilitates small floating adjustments of the heating plate during the installation process to ensure the concentricity of the heating plate and the stirring cup.
[0028] 9. In the case where the heating plate is provided with a boss, when the height of the boss is small, the stirring blade assembly will be closer to the bottom of the heating plate, which will not easily stir the material and may cause part of the material to settle at the bottom, causing the bottom to become sticky. By setting the top of the boss higher than the bottom of the stirring cup, the stirring blade assembly can have a suitable installation height, so that the blade is at least partially located in the main crushing chamber, which is conducive to driving the interaction between the material and the spoiler ribs on the cup wall, enhancing the turbulent effect, and improving the crushing efficiency.
[0029] The stirring blade assembly includes a horizontally extending base, and the spacing between the base and the boss is 5-20 mm. When the spacing between the base and the boss is too small, interference between the blade and the boss may occur. When the spacing between the base and the boss is too large, the rotational stability of the tool deteriorates, and it is easy to shake and cause the tool to get stuck.

[0043] like Figures 1 to 3 As shown, the present application provides a food processor, including a cup body assembly 10 with a motor assembly 15 installed therein, the cup body assembly 10 including a stirring cup 11 with an opening at the bottom, a heating plate 12 arranged at the opening, and a cup body bracket 13, a stirring blade assembly 16 driven by the motor assembly 15 is provided in the stirring cup 11, the heating plate 12 is clamped and fixed by the stirring cup 11 and the cup body bracket 13, the heating plate 12 is arranged to convex downward relative to the stirring cup 11, an auxiliary crushing cavity 121 is formed on the inner side of the heating plate 12, the motor assembly 15 is fixed to the outer side of the heating plate 12 corresponding to the auxiliary crushing cavity 121, the heating plate 12 includes a heating plate main body 122 and a heating tube 123 integrally die-cast on the heating plate main body 122, the upper end of the motor shaft 151 of the motor assembly 15 passes through the heating plate 12 and extends into the stirring cup 11 and is fixed to the stirring blade assembly 16.
[0044] Compared to the convex heating plate in the prior art, the present application adopts a heating plate 12 shape that is convex relative to the cup body. The concave space of the heating plate 12 itself can constitute a part of the crushing space. When a certain processing chamber capacity is required, it is conducive to using a smaller cup body, thereby reducing costs. Furthermore, the shape of the heating plate 12 of the present application allows the outer side of the heating plate 12 to have a relatively open space. When installing the motor assembly 15, there is no need to confine the motor assembly 15 to a small space. It can adapt to the installation of motor assemblies 15 of more sizes. Moreover, when the motor assembly 15 is free from being wrapped, the heat dissipation efficiency of the motor assembly 15 is higher, so that the motor assembly 15 maintains a suitable temperature and avoids excessive temperature affecting its performance and life. An auxiliary crushing chamber 121 is formed on the inner side of the heating plate 12 to increase the contact area between the material and the heating plate 12. The material is easier to crush after being heated and softened in the auxiliary crushing chamber 121, which can improve the crushing effect.
[0045] like Figure 2 and Figure 3As shown, the heating plate 12 of the present application is clamped by the stirring cup 11 and the cup body bracket 13. The heating plate 12 is bowl-shaped and is located below the stirring cup 11 without being embedded in the cup body, which is conducive to the heating plate 12 and the stirring cup 11 to enclose and form a larger crushing space. The stirring cup 11 and the cup body bracket 13 can be fixed by means such as threaded connection or snap connection, and the two clamp the heating plate 12 together. The heating plate 12 adopts an integrated structure, and the heating tube 123 is integrally die-cast on the heating plate body 122. In this way, the heat of the heating tube 123 is more efficiently transferred to the heating plate body 122, and the heat conduction effect is good. Preferably, the heating tube 123 is arranged in an area near the edge of the heating plate 12, so that the area near the middle of the heating plate 12 has sufficient space to install other components.
[0046] A cup housing 14 is provided on the outer side of the lower end of the blending cup 11, enclosing the cup support 13, blending cup 11, heating plate 12, and motor assembly 15, giving the cup assembly 10 a simple appearance. An upper coupler 141 is provided at the bottom of the cup housing 14, and a lower coupler is provided on the main unit 17 of the food processor. When the cup assembly 10 is placed on the main unit 17, the upper and lower couplers cooperate to provide power. The blending blade assembly 16 may include one or more blades, which may be riveted to the motor shaft 151. Directly securing the blades to the motor shaft 151 eliminates the need for a blade shaft, facilitating more stable operation. An auxiliary crushing chamber 121 is formed within the heating plate 12, while a main crushing chamber 111 is formed within the blending cup 11 above the heating plate 12. The material at the bottom of the blending cup 11 is heated and softened in the auxiliary crushing chamber 121. After the blades are activated, the material passes through the auxiliary crushing chamber 121 and reaches the main crushing chamber 111. Ultimately, under the influence of turbulent ribs and gravity, the material falls back to the vicinity of the blades for crushing.
[0047] Preferably, a sealing ring 18 is provided on the edge of the heating plate 12, and the sealing ring 18 is clamped by the mixing cup 11 and the cup body bracket 13. The sealing ring 18 can provide a seal to prevent liquid from flowing from the matching gap between the heating plate 12 and the mixing cup 11 into the cup body shell 14 below to damage the internal electrical components, and prevent materials or residues from being caught in the matching gap between the heating plate 12 and the mixing cup 11 and causing odor. It is also beneficial for the heating plate 12 to be slightly floated and adjusted during the installation process to ensure the concentricity of the heating plate 12 and the mixing cup 11. Figure 2 As shown, the sealing ring 18 adopts a C-shaped structure and is sleeved on the edge of the heating plate 12 through a lateral opening.
[0048] As a preferred embodiment, a mounting platform 124 is provided on the bottom side of the heating plate 12 corresponding to the auxiliary crushing chamber 121 , and the motor assembly 15 is flexibly suspended on the mounting platform 124 .
[0049] The existing upward convex heating plate is provided with a accommodating cavity with an opening facing downwards, and the upper end of the motor needs to be accommodated in the accommodating cavity. The limited space of the accommodating cavity leads to limited space for the motor installation, which is not conducive to the installation of larger-sized motors. In order to solve this problem, the present application forms an open mounting platform 124 on the bottom side of the heating plate 12, which does not limit the motor assembly 15 to be wrapped in a small space. The motor assembly 15 is hoisted on the mounting platform 124, which can not only meet the installation requirements of motor assemblies 15 of more sizes, but also a gap is usually formed between the motor assembly 15 and the mounting platform 124, which is conducive to the heat dissipation of the motor assembly 15, and can meet the heat dissipation requirements of the motor assembly 15. When the motor assembly 15 is flexibly installed, the vibration of the motor assembly 15 can be prevented from being transmitted to the heating plate 12 to affect the firmness of the installation of the heating plate 12, and the cup body assembly 10 can be made to run more smoothly with less working noise.
[0050] Specifically, the mounting platform 124 is disposed in the area inside the heating tube 123. Since the motor assembly 15 is suspended, the maximum outer diameter of the motor assembly 15 can be larger than the width of the mounting platform 124 without affecting the installation of the motor assembly 15. Preferably, the motor assembly 15 is disposed inside the heating tube 123 to reduce the radiation of heat from the heating tube 123 to the motor assembly 15, thereby preventing the motor assembly 15 from overheating.
[0051] As a preferred embodiment of the present embodiment, the mounting platform 124 is provided with a screw column for fixing the motor assembly 15 , and the mounting platform 124 is also fixed with a temperature controller 19 for detecting the temperature of the heating disk 12 on the radial inner side of the screw column.
[0052] The space of the accommodating cavity of the above-mentioned existing heating plate is limited. In order to realize the installation of multiple components such as the thermostat and the motor, a heating plate with a larger radial size needs to be used, which results in the heating plate and the cup body being larger in size, which is not conducive to the miniaturization and lightness of the machine. The present application has sufficient space to install the motor assembly 15 and the thermostat 19 on the premise of forming an open mounting platform 124, thereby improving the space utilization rate. A screw column is provided on the mounting platform 124 for fixing the motor assembly 15, which is not only simple in structure but also occupies less space, so that there is more space in other areas of the mounting platform 124 for arranging the thermostat 19, effectively solving the installation problem of multiple components on the heating plate 12 and promoting the compactness of the component arrangement.
[0053] Specifically, the motor assembly 15 includes, for example, a motor upper cover, a motor body, and a motor lower cover. The motor upper cover and the motor lower cover are clamped with the motor body. The motor upper cover is provided with a mounting hole, and a shock-absorbing pad is provided in the mounting hole. The motor assembly 15 can be installed by passing a screw column through the shock-absorbing pad and then tightening the screw. A heat dissipation gap is provided between the mounting platform 124 and the motor upper cover, which is beneficial to the heat dissipation of the motor assembly 15 and can reduce the heat transferred from the heating plate 12 to the motor assembly 15, thereby preventing the motor assembly 15 from overheating and affecting its performance and life. Figure 3 As shown, the temperature controller 19 is arranged on the radial inner side of the screw column, which does not affect the installation of the motor assembly 15 and fully utilizes the space of the heating plate 12.
[0054] In addition to the aforementioned method of fixing the heating plate 12 to the motor upper cover, in other embodiments, the motor upper cover can be omitted, and the motor assembly 15 includes a motor body and a motor lower cover, which are fixed by the heating plate 12 and the motor lower cover. For example, the heating plate 12 and the motor lower cover do not completely cover the motor body, and a mounting gap is provided between the heating plate 12 and the motor lower cover to meet the heat dissipation of the motor assembly 15.
[0055] As a preferred embodiment, the heating plate 12 includes a base 125 and a rim 126 bent upward from the edge of the base 125. The space from the top of the rim 126 to the base 125 forms an auxiliary crushing chamber 121, and the space from the bottom end of the stirring cup 11 to the top end of the stirring cup 11 forms a main crushing chamber 111 connected to the auxiliary crushing chamber 121.
[0056] In this application, the blending cup 11 and heating plate 12 cooperate to form a primary crushing chamber 111 and an auxiliary crushing chamber 121 from top to bottom. While maintaining the cup dimensions, the overall crushing space is expanded, enabling the production of larger beverages while also enhancing the crushing efficiency. The material tumbles between the auxiliary crushing chamber 121 and the primary crushing chamber 111, increasing turbulence and the contact area between the material and the heating plate 12. After being heated and softened in the auxiliary crushing chamber 121, the material is more easily crushed, thus enhancing the crushing efficiency.
[0057] As a preferred embodiment, the heating plate 12 includes a base plate 125 and a boss 127 protruding upward from the center of the base plate 125 , and the stirring blade assembly 16 is suspended above the boss 127 .
[0058] like Figure 3 As shown, by providing a boss 127, it can support and limit the motor shaft 151, preventing the upper end of the motor shaft 151 from shaking and affecting the stability of the stirring blade assembly 16. Preferably, the boss 127 is formed by directly raising a portion of the chassis 125 during processing, and a certain space is formed on the outside of the boss 127 to form a receiving cavity 128 for mounting the inner seal assembly 20 and the bearing 21, thereby improving space utilization.
[0059] like Figure 3 As shown, an accommodating cavity 128 is formed on the outer side of the boss 127 , and an inner sealing assembly 20 and a bearing 21 that cooperate with the motor shaft 151 are sequentially provided in the accommodating cavity 128 in a direction away from the stirring blade assembly 16 .
[0060] The provision of the inner seal assembly 20 prevents liquid in the pulverizing chamber from flowing through the gap between the boss 127 and the motor shaft 151 onto the motor assembly 15 below, thereby damaging the structure of the motor assembly 15. The provision of the bearing 21 ensures the stability of the operation of the stirring blade assembly 16 driven by the motor shaft 151. The boss 127 preferably increases in diameter from top to bottom. Under the premise that the accommodating chamber 128 has sufficient space to accommodate the bearing 21, the inner side of the boss 127 occupies as little space in the pulverizing chamber as possible, thereby increasing the contact area between the material and the heating plate 12.
[0061] In one embodiment, the top of the boss 127 is arranged higher than the bottom of the blending cup 11 , and the blending blade assembly 16 includes a horizontally extending base 161 , and the distance between the base 161 and the boss 127 is 5-20 mm.
[0062] When the height of the boss 127 is relatively small, the stirring blade assembly 16 will be closer to the bottom of the heating plate 12, making it difficult to stir the material and some of the material may be deposited at the bottom, causing a sticky bottom. By setting the top of the boss 127 higher than the bottom of the stirring cup 11, the stirring blade assembly 16 can have a suitable installation height, so that the blade is at least partially located in the main crushing chamber 111, which is conducive to driving the interaction between the material and the spoiler ribs on the cup wall, enhancing the turbulent effect, and improving the crushing efficiency.
[0063] like Figure 3 As shown, the stirring blade assembly 16 includes a horizontally extending base 161 and a plurality of blades 162 arranged around the base 161. The blades 162 include at least two types: upwardly bent, downwardly bent, and horizontally extended, so as to have a larger cutting range in the axial direction and improve the cutting effect of the food. By setting a reasonable spacing, the stability and reliability of the stirring blade assembly 16 can be guaranteed. When the spacing between the base 161 and the boss 127 is too small, interference between the blade and the boss 127 may occur. When the spacing between the base 161 and the boss 127 is too large, the rotational stability of the tool deteriorates, and it is easy to shake and cause the tool to get stuck.
[0064] In a preferred embodiment, the motor of the motor assembly 15 of the present application can be a brushless motor. On the one hand, the brushless motor is small in size and light in weight, which can reduce the installation burden of the heating plate 12, which is beneficial to the stable operation of the cup body assembly 10. On the other hand, the flattening of the brushless motor can reduce the overall axial size of the cup body assembly 10, which is beneficial to the miniaturization and lightness of the entire machine.
