Description

Technical Field

[0001] This invention relates to the field of household appliances, and in particular to a heated food processing machine. Background Technology

[0002] The use of household food processors is becoming increasingly popular, such as soy milk makers and food processors. The cup body is generally made of inner steel and outer plastic. The water level line is printed in the stainless steel inner liner, which makes it impossible to see the water level line from the outside of the cup body. When the machine head is closed, users cannot observe the entire process of making soy milk, which affects the user experience.

[0003] Furthermore, existing stainless steel heating cups have a high thermal conductivity, causing rapid temperature increases on both the bottom and sides of the cup (below the liquid surface) and the sides above the liquid surface during the heating of soy milk / rice paste. When boiling, this produces a large amount of foam, which expands rapidly upon contact with the hot sides of the cup and quickly overflows. Additionally, hard foods hitting the stainless steel body create significant noise.

[0004] In existing technologies, the side walls of the cup are replaced with glass, and a hole is opened at the bottom of the glass, through which a bottom heating plate (i.e., the heating tube is set on the bottom wall of the cup) is installed. In existing glass cups, the connection between the heating plate and the glass body generally falls into the following categories: One is the technical solution disclosed in CN201610278256.8, where the outer edge of the heating plate forms a groove, the lower end of the cup body is inserted into the groove, and then it is fixed by applying glue. This method, for aesthetic purposes, requires a high level of skill in the glue application process and is slow in processing efficiency. Another method is the technical solution disclosed in application number CN201020503000.0, where the cup body has an inwardly extending horizontal edge, the outer edge of the heating plate is located above the horizontal edge, and a bracket is located below the horizontal edge. The bracket and the heating plate are fixedly clamped onto the horizontal edge for sealing and fixation. This method, for ease of installation of the heating plate, has certain requirements on the size of the cup body, is not conducive to the aesthetic design of the cup body, and is costly. Meanwhile, the above heating method is planar heating, which is particularly slow for non-aquatic foods such as soy milk, resulting in long waiting times and a poor user experience. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a food processing machine that is easy to install and has good stability.

[0006] To achieve the objectives of this invention, the technical solution adopted is as follows: A food processing machine includes a cup body assembly and a cup lid disposed above the cup body assembly. The cup body assembly includes a glass body that extends vertically through the body and a heating plate that is connected to the lower part of the body. The lower part of the body has a bottom surface, and the heating plate has a support surface. The bottom surface and the support surface are sealed together. The inner edge of the support surface is recessed downward to form a receiving cavity. A heating element is disposed on the outer surface of the receiving cavity. The outer edge of the support surface extends upward to form a connecting portion, and the connecting portion is connected to the outer wall of the body.

[0007] Furthermore, the ratio of the height H1 of the receiving cavity to the height of the glass pot body ranges from 1 to 15, and the height H1 of the receiving cavity is greater than 8 mm.

[0008] Furthermore, the cup assembly also includes a crushing structure, which includes a blade. The distance from the blade to the bottom of the receiving cavity is H2, and the height of the receiving cavity is H1, where H1 is greater than H2.

[0009] Furthermore, the outer wall of the lower part of the pot body is provided with an outwardly protruding step, and the top of the connecting part is curled up and pressed against the top of the step.

[0010] Furthermore, the width of the step is 0.5 mm to 5 mm.

[0011] Furthermore, the outer wall of the kettle body and the inner wall of the heating plate are provided with rotating buckles that are relatively protruding and cooperate with each other.

[0012] Furthermore, a first protrusion is provided on the outer side wall of the lower part of the kettle body, and a second protrusion is provided on the connecting part. The first protrusion is spirally arranged on the outer side wall of the lower part of the kettle body to form a threaded protrusion, and the second protrusion is spaced out on the connecting part of the heating plate to form protrusions or spirally arranged to form a threaded protrusion. The first protrusion and the second protrusion are connected in cooperation. Alternatively, a first protrusion is provided on the outer side wall of the lower part of the kettle body, and a second protrusion is provided on the connecting part. The first protrusion is provided at intervals on the outer side wall of the lower part of the kettle body to form protrusions, and the second protrusion is provided at intervals on the connecting part of the heating plate to form protrusions or spirally to form threaded protrusions. The first protrusion and the second protrusion are connected in cooperation.

[0013] Furthermore, the top end of the connecting portion extends outward to form a flange.

[0014] Furthermore, the flange forms a groove with the outer side of the connecting part, and also includes a bottom cover located below the cup body, with the outer edge of the bottom cover embedded in the groove; or, the flange is a rolled edge.

[0015] Furthermore, the bottom surface of the kettle body and the supporting surface are sealed together by an annular sealing ring. The supporting surface is provided with an opening, and the sealing ring is provided with a raised rib, which is embedded in the opening; or, the bottom surface of the kettle body and the supporting surface are sealed together by an annular sealing ring. The supporting surface is provided with a groove, and the sealing ring is located in the groove.

[0016] The beneficial effects of this invention are as follows: Using the above technical solution, a supporting surface is provided on the metal heating plate, and the bottom surface of the lower part of the glass (i.e., the bottom end face) mates with the supporting surface. A sealing ring or sealant is provided between the supporting surface and the bottom surface of the lower part of the glass to seal the heating plate and the glass pot body. Furthermore, the outer edge of the heating plate connects to the outer wall of the pot body. This eliminates the need to consider the dimensions of the upper and lower mounting openings of the glass pot body, facilitating the design of the pot body and the installation of the heating plate and pot body. On the other hand, it further improves the horizontal sealing effect between the heating plate and the bottom surface of the pot body. Simultaneously, it reduces the impact area of ​​food on the metal surface, lowers noise, and the inclusion of a cavity also achieves the goal of accelerating heating efficiency—a win-win situation.

[0017] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description, claims, and drawings.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0022] Example 1: like Figure 1 As shown, a cup assembly includes a glass body 1 that runs vertically through the body, and a metal heating plate 2 that is connected to the lower part of the body 1. The lower part of the body 1 has a bottom surface, and the heating plate 2 has a support surface 211. The bottom surface and the support surface 211 are sealed together. The outer edge of the support surface 211 extends upward to form a connecting part 212. The connecting part 212 wraps around the outer wall of the body 1 and is connected to the outer wall of the body 1.

[0023] In existing glass cups, the connection between the metal heating plate 2 and the glass body 1 generally follows these methods: One method involves forming a groove 215 along the outer edge of the heating plate 2, inserting the lower end of the glass body 1 into the groove 215, and then fixing it with adhesive. This method requires a high level of skill in the adhesive application process for aesthetic purposes and is slow in processing. Another method involves the glass body 1 having an inwardly extending horizontal edge, with the outer edge of the heating plate 2 located above the horizontal edge, and a support located below the horizontal edge. The support and the heating plate 2 are fixedly clamped onto the horizontal edge for sealing. This method requires certain dimensions of the glass body 1 for easy installation of the heating plate 2 and is not conducive to the aesthetic design of the cup. Both of these connection methods create a cleaning dead zone between the heating plate 2 and the inner wall of the glass body 1. For example, in the second method, the outermost edge of the heating plate 2 is a certain distance from the inner wall of the glass body 1. Due to the presence of the sealing gasket, the outermost edge of the heating plate 2 forms a groove 215 with the inner wall of the glass body 1, making it easy for residue to accumulate in the groove 215, which is not conducive to cleaning.

[0024] The present invention adopts the above-mentioned technical solution. The metal heating plate 2 is provided with a support surface 211. The bottom surface of the lower part of the glass (i.e., the bottom end face) cooperates with the support surface 211. A sealing ring 4 or sealant is provided between the support surface 211 and the bottom surface of the lower part of the glass to seal the heating plate 2 and the glass pot body 1. The outer edge of the heating plate 2 is connected to the outer side wall of the pot body 1. At this time, it is not necessary to consider the size of the upper and lower installation openings of the glass pot body 1, which facilitates the design of the pot body 1 and the installation of the heating plate 2 and the pot body 1. On the other hand, it is more conducive to improving the sealing effect of the heating plate 2 and the bottom surface of the pot body 1 in the horizontal direction.

[0025] Furthermore, the inner edge of the support surface 211 extends downward to form a bowl-shaped receiving cavity. The support surface 211 is sealed to the bottom surface of the glass pot body 1. The inner wall of the pot body 1 extends longitudinally to the inner wall of the receiving cavity. The end-face sealing ensures that residues such as soy milk or food scraps will not enter the joint between the bottom surface of the glass and the support surface 211, preventing residue buildup and facilitating cleaning. This solves the problem of forming cleaning dead corners. The bowl shape can include side walls and a bottom wall, or it can be spherical.

[0026] Furthermore, the glass body 1 is provided with a constricting structure, and the upper end of the connecting part 212 is located below the constricting structure. This constricting structure can maintain the overall aesthetics of the cup body and also strengthen the glass body 1.

[0027] Example 2: The use of household liquid heaters is becoming increasingly common, such as electric kettles and soy milk makers. Their cups are generally made of inner steel and outer plastic, and the water level line is printed in the stainless steel inner liner. The water level line cannot be seen from the outside of the cup. When the lid is closed, users cannot observe the entire process of making soy milk or boiling / cooking food in the electric kettle, which affects the user experience.

[0028] In addition, existing stainless steel heating cups conduct heat too quickly. During the heating of soy milk / rice paste, the temperature of the bottom and sides of the cup below the liquid surface and the side surface above the liquid surface rise rapidly. When boiling, a large amount of foam is produced. When the foam encounters the hot side surface of the cup above the liquid surface, it continues to expand and quickly overflows.

[0029] In existing technologies, the side walls of the cup are replaced with glass, and a hole is opened at the bottom of the glass, through which a bottom heating plate 2 (i.e., the heating tube is set on the bottom wall of the cup) is installed. In existing glass cups, the connection between the heating plate 2 and the glass body 1 generally has the following solutions: One is that the outer edge of the heating plate 2 forms a groove 215, the lower end of the body 1 is inserted into the groove 215, and then it is fixed by applying glue. This method requires high precision in the glue application process and is slow in processing efficiency for aesthetic purposes. Another method is that the body 1 has an inwardly extending horizontal edge, the outer edge of the heating plate 2 is located above the horizontal edge, and a bracket is also provided below the horizontal edge. The heating plate 2 is fixedly clamped to the horizontal edge by the bracket for sealing and fixation. This method requires certain dimensions of the body 1 for easy installation of the heating plate 2 and is not conducive to the aesthetic design of the cup. In both of the above connection methods, a cleaning dead zone is formed between the heating plate 2 and the inner wall of the pot body 1. For example, in the second method, the outermost edge of the heating plate 2 is a certain distance from the inner wall of the glass pot body 1. Due to the presence of the sealing gasket, the outermost edge of the heating plate 2 and the inner wall of the glass pot body 1 form a groove 215, and residue is easy to accumulate in the groove 215, which is not conducive to cleaning.

[0030] In addition, if the heating element 3 (such as a heating tube) is placed on the bottom wall of the cup body, the heating plate 2 may be visible, but the bottom heating plate 2 may easily cause problems such as sticking to the bottom during the soy milk making process or limescale when boiling water.

[0031] To address the aforementioned technical problems, a cup body component is proposed, such as... Figure 1As shown, the device includes a glass body 1 that runs vertically through the body, and a metal heating plate 2 that is connected to the lower part of the body 1. The lower part of the body 1 has a bottom surface, and the heating plate 2 has a support surface 211. The bottom surface and the support surface 211 are sealed together. The outer edge of the support surface 211 extends upward to form a connecting part 212. The connecting part 212 wraps around the outer wall of the body 1 and is connected to the outer wall of the body 1. The inner edge of the support surface 211 extends downward to form a bowl-shaped receiving cavity. The receiving cavity includes a side wall and a bottom wall, and a heating element 3 is disposed on the outer surface of the side wall.

[0032] The cup assembly includes a separate glass body 1 and a metal heating plate 2. Glass has poor thermal conductivity, so heat from the metal heating plate 2 is not easily conducted to the glass body 1 during heating. Therefore, the temperature of the glass body 1 is relatively lower than that of the metal heating plate 2. When foam encounters the cooler side of the glass, it contracts, preventing overflow. Furthermore, stainless steel heating cups typically have a wall thickness of only 0.5mm. Due to this thin wall, the elastic modulus is low, and during the soymilk maker's blades 6, the material impacts the side wall of the cup, generating significant impact noise. Using a glass body 1, due to its relatively thicker glass and higher elastic modulus, reduces the noise generated by the material impacting the side wall. The thickness of the glass body 1 is between 2.5mm and 5mm, at which point the glass achieves a better noise reduction effect.

[0033] In this embodiment, the metal heating plate 2 is provided with a support surface 211. The bottom surface of the lower part of the glass (i.e., the bottom end face) cooperates with the support surface 211. A sealing ring 4 or sealant is provided between the support surface 211 and the bottom surface of the lower part of the glass to seal the heating plate 2 and the glass pot body 1. The outer edge of the heating plate 2 is connected to the outer side wall of the pot body 1. At this time, it is not necessary to consider the size of the upper and lower mounting openings of the glass pot body 1, which facilitates the design of the pot body 1 and the installation of the heating plate 2 and the pot body 1. On the other hand, it is more conducive to improving the sealing effect of the heating plate 2 and the bottom surface of the pot body 1 in the horizontal direction. The inner edge of the support surface 211 extends downward to form a bowl-shaped receiving cavity. The support surface 211 is sealed to the bottom surface of the glass pot body 1. The inner wall of the pot body 1 extends longitudinally to the inner wall of the receiving cavity. The end-face sealing ensures that residues such as soy milk or food scraps will not enter the joint between the bottom surface of the glass and the support surface 211, preventing residue buildup and facilitating cleaning. This solves the problem of forming cleaning dead corners. The bowl shape can include side walls and a bottom wall, or it can be spherical.

[0034] In summary, the heating plate 2 is bowl-shaped, and the heating element 3 is located on the outer side of the heating plate 2. This forms a cavity for the heated liquid without affecting the heating rate. Furthermore, it prevents scorching and water stains or scale buildup during dry heating. Specifically, the heating plate 2 has a horizontal support surface 211 that seals against the bottom surface of the kettle body 1. One end of the support surface 211 extends to connect with the outer side of the kettle body 1, and the other end extends to form a cavity. The heating element 3 is located on the side wall of this cavity. This design solves both the installation problems of the heating plate 2 and the kettle body 1, as well as the problem of dirt and grime accumulation. It also allows for changes in the installation position of the heating element 3, thus resolving the issues of scorching and water stains or scale buildup.

[0035] Furthermore, in order to improve the heating effect of the area heated by the heating element 3 and to achieve a better anti-overflow effect of the cup body, the ratio of the height H1 of the receiving cavity to the height H3 of the glass pot body 1 is in the range of 2 to 15, with a preferred value of 5, and the height H1 of the receiving cavity is greater than 8mm.

[0036] Furthermore, the glass body 1 is provided with a constricting structure, and the upper end of the connecting part 212 is located below the constricting structure. This constricting structure can maintain the overall aesthetics of the glass body and also strengthen the glass body 1. A buffer can also be provided between the upper end of the connecting part 212 and the constricting position.

[0037] Example 3: Based on the structure of Embodiment 1 and / or Embodiment 2 described above, the connection method between the connecting part 212 and the glass pot body 1 can be as follows: The first type, such as Figure 1 and Figure 2 As shown, the outer side wall of the lower part of the kettle body 1 is provided with an outwardly protruding step 11, and the top end of the connecting part 212 is curled and pressed against the step 11. The deformation of the circular rolled edge 213 structure on the heating plate 2 is used to press the glass kettle body 1, so that the glass kettle body 1 and the circular rolled edge 213 structure are interlocked. The sealing ring 4 on the end face forms a lasting pre-tightening force, ensuring the reliability of the side seal between the glass kettle body 1 and the heating plate 2.

[0038] This snap-fitting and riveting method can prevent the heating plate 2 and the glass body 1 from detaching, ensuring a reliable connection between the two. At the same time, this snap-fitting connection method reduces the direct overlap between the heating plate 2 and the glass body 1, thereby effectively increasing the visible space of the glass body 1 and making the entire cup more aesthetically pleasing.

[0039] Furthermore, the width of the step 11 is 0.5mm to 5mm. Preferably, it is 2mm, at which point the step 11 is not easily broken, and the fastening is secure and not easily loosened.

[0040] The second type involves a rotating buckle with opposing protrusions on the outer wall of the kettle body 1 and the inner wall of the heating plate 2. This buckle connects the heating plate 2 and the glass kettle body 1 as a single unit through rotation. The rotational torque creates a clamping force between the glass kettle body 1 and the heating plate 2, ensuring a secure connection and simultaneously tightening the sealing ring 4, preventing separation. For example, the lower outer wall of the kettle body 1 has a first protrusion, and the connecting part 212 has a second protrusion. The protrusion directions of the first and second protrusions are opposite. The first protrusion is an outward (away from the center of the kettle body 1) structure on the lower outer wall of the kettle body 1, and the second protrusion is an inward (towards the center of the kettle body 1) structure on the connecting part 212. Specifically, as follows: like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first protrusion is arranged at intervals on the outer side wall of the lower part of the kettle body 1 to form a swivel, and the second protrusion is arranged at intervals on the connecting part 212 of the heating plate 2 to form a protrusion 214 or a spiral arrangement to form a threaded protrusion 13. The first protrusion and the second protrusion are connected together.

[0041] For example, when the first protrusion is a snap fastener including a snap fastener platform 122, a snap fastener inclined surface 121, and a snap fastener stop rib 123, the second protrusion is a protrusion 214. When the connecting part 212 of the heating plate 2 is rotated and snapped onto the outer wall of the kettle body 1, the snap fastener inclined surface 121 can lift the heating plate 2, the snap fastener platform 122 is used to control the amount of compression, and after rotation into place, the snap fastener protrusion 214 is located on the snap fastener platform 122, and the snap fastener stop rib 123 is used to restrict the snap fastener protrusion 214 to prevent it from coming off when tightened in the forward direction. Preferably, the connecting part 212 is provided with 8 protrusions 214 and 8 snap fasteners.

[0042] Or, such as Figure 8 , Figure 9 and Figure 10 As shown, the first protrusion is spirally arranged on the outer side wall of the lower part of the kettle body 1 to form a threaded protrusion 13, and the second protrusion is spaced out on the connecting part 212 of the heating plate 2 to form protrusions 214 or spirally arranged to form a threaded protrusion 13. The first protrusion and the second protrusion are connected together.

[0043] For example, when the first protrusion is a threaded protrusion 13 and the second protrusion is a dot 214, the heating plate 2 is connected to the glass pot body 1 through the dot 214 and the threaded protrusion 13.

[0044] Based on the above solution of this embodiment, the top end of the connecting portion 212 extends outward to form a flange. Specifically: like Figure 4 As shown, the flange and the outer side of the connecting part 212 form a groove 215, and a bottom cover located below the cup body is also included. The outer edge of the bottom cover is embedded in the groove 215. The groove 215 and the upper edge of the bottom cover are fitted together for easy assembly. In addition, a decorative ring can be formed at the connection between the cup body 1 and the bottom cover to enhance the aesthetics. At this time, a stop structure can be provided on the outer side wall of the upper edge of the bottom cover to make the fit between the flange and the bottom cover more stable, and also improve the fit. Or, such as Figure 10 As shown, in order to prevent the heating plate 2 from scratching hands during installation or to facilitate the installation of the bottom cover, the flange is provided as a rolled edge 216.

[0045] Of course, in addition to the above-mentioned flange structure, the flange also includes a horizontal edge that extends only horizontally. In this case, the bottom cover can also be fitted. In an improved manner, a silicone pad or other structure can also be fitted on the above-mentioned flange.

[0046] In addition to the connection methods mentioned above, there is a third type: the outer wall of the lower part of the pot body 1 is provided with an inwardly recessed mounting groove, and the connecting part 212 has a protruding point 214 that protrudes inward (towards the pot body 1), and the second protruding point 214 is embedded in the mounting groove for fixation.

[0047] Example 4: Based on any of the structures in Embodiments 1 to 3 above, in order to improve the sealing effect and aesthetics, such as... Figure 2 As shown, the bottom surface and the supporting surface 211 are sealed together by an annular sealing ring 4. The supporting surface 211 is provided with an opening, and the sealing ring 4 is provided with a raised rib. The raised rib is embedded in the opening to prevent the sealing ring 4 from being misaligned during the installation of the glass pot body 1 and the heating plate 2, which would affect the sealing effect and aesthetics.

[0048] Or, such as Figure 4 As shown, the bottom surface of the kettle body 1 and the supporting surface 211 are sealed together by an annular sealing ring 4. The supporting surface 211 has a groove 215, and the sealing ring 4 is located within the groove 215. The groove 215 is located on the outer side of the supporting surface 211, and the inner end of the supporting surface 211 can fit tightly against the bottom surface of the kettle body 1 (with a small gap allowed), reducing the possibility of forming cleaning dead zones. Furthermore, the first protrusion can further press the sealing ring 4 firmly.

[0049] Example 5: The use of household soy milk makers is becoming increasingly popular. The soy milk maker cup body generally adopts an inner steel and outer plastic structure. The water level line is printed in the stainless steel inner liner, making it impossible to see the water level line from the outside of the cup body. When the machine head is closed, users cannot observe the entire process of making soy milk, which affects the user experience.

[0050] In addition, existing stainless steel heating cups conduct heat too quickly. During the heating of soy milk / rice paste, the temperature of the bottom and sides of the cup below the liquid surface and the side surface above the liquid surface rise rapidly. When boiling, a large amount of foam is produced. When the foam encounters the hot side surface of the cup above the liquid surface, it continues to expand and quickly overflows.

[0051] In existing technology, one approach is to replace the side wall of the soymilk maker cup with glass, and to have a hole at the bottom of the glass with a bottom heating plate 2 installed therein. While this approach allows for visualization during the soymilk making process, the bottom heating plate 2 can easily lead to problems such as scorching at the bottom of the soymilk.

[0052] To solve the above technical problems, such as Figure 11 As shown, a soymilk maker is proposed, including a cup body assembly and a machine head 5 disposed above the cup body assembly. The cup body assembly includes a glass pot body 1 that runs vertically through the body, and a heating plate 2 that is connected to the lower part of the pot body 1. The lower part of the pot body 1 has a bottom surface, and the heating plate 2 has a support surface 211. The bottom surface and the support surface 211 are sealed together. The inner edge of the support surface 211 is recessed downward to form a receiving cavity. A heating element 3 is disposed on the outer surface of the receiving cavity. The outer edge of the support surface 211 extends upward to form a connecting part 212, and the connecting part 212 is connected to the outer side wall of the pot body 1.

[0053] Using the above technical solution, the cup assembly includes a separate glass body 1 and a metal heating plate 2. Glass has poor thermal conductivity, so heat from the metal heating plate 2 is not easily conducted to the glass body 1 during heating. Therefore, the temperature of the glass body 1 is relatively lower than that of the metal heating plate 2. When foam encounters the cooler side of the glass, it contracts, thus preventing overflow. Furthermore, stainless steel heating cups typically have a wall thickness of only 0.5mm. Due to this thin wall, the elastic modulus is low, and during the soymilk maker's blades 6, the material impacts the side wall of the cup, generating significant impact noise. When using the glass body 1, the relatively thicker glass has a higher elastic modulus, which reduces the noise generated by the material impacting the side wall. The thickness of the glass body 1 is between 2.5mm and 5mm, at which point the glass achieves a better noise reduction effect.

[0054] In this embodiment, the metal heating plate 2 is provided with a support surface 211. The bottom surface of the lower part of the glass (i.e., the bottom end face) cooperates with the support surface 211. A sealing ring 4 or sealant is provided between the support surface 211 and the bottom surface of the lower part of the glass to seal the heating plate 2 and the glass pot body 1. The outer edge of the heating plate 2 is connected to the outer side wall of the pot body 1. At this time, it is not necessary to consider the size of the upper and lower mounting openings of the glass pot body 1, which facilitates the design of the pot body 1 and the installation of the heating plate 2 and the pot body 1. On the other hand, it is more conducive to improving the sealing effect of the heating plate 2 and the bottom surface of the pot body 1 in the horizontal direction. The inner edge of the support surface 211 extends downward to form a bowl-shaped receiving cavity. The support surface 211 is sealed to the bottom surface of the glass pot body 1. The inner wall of the pot body 1 extends longitudinally to the inner wall of the receiving cavity. The end-face sealing ensures that residues such as soy milk or food scraps will not enter the joint between the bottom surface of the glass and the support surface 211, preventing residue buildup and facilitating cleaning. This solves the problem of forming cleaning dead corners. The bowl shape can include side walls and a bottom wall, or it can be spherical.

[0055] In summary, the heating plate 2 is bowl-shaped, and the heating element 3 is located on the outer side of the heating plate 2. This forms a cavity for the heated liquid without affecting the heating rate. Furthermore, it prevents scorching and water stains or scale buildup during dry heating. Specifically, the heating plate 2 has a horizontal support surface 211 that seals against the bottom surface of the kettle body 1. One end of the support surface 211 extends to connect with the outer side of the kettle body 1, and the other end extends to form a cavity. The heating element 3 is located on the side wall of this cavity. This design solves both the installation problems of the heating plate 2 and the kettle body 1, as well as the problem of dirt and grime accumulation. It also allows for changes in the installation position of the heating element 3, thus resolving the issues of scorching and water stains or scale buildup.

[0056] Furthermore, in order to improve the heating effect of the area heated by heating element 3, and at the same time achieve a better anti-overflow effect for the cup body, such as... Figure 11 As shown, the ratio of the height H1 of the receiving cavity to the height H3 of the glass pot body 1 ranges from 3 to 8, and the height H1 of the receiving cavity is greater than 10 mm. Preferably, the ratio is 5, and H1 is 13-20 mm. Furthermore, such as Figure 12As shown, the machine head 5 includes a blade 6 extending into the cup assembly. The distance from the blade 6 to the bottom of the receiving cavity is H2, and the height of the receiving cavity is H1. H1-H2 ≥ 3mm, preferably greater than 5mm and less than 10mm. During the soy milk maker's re-making process, the motor drives the blade 6 to rotate at high speed. At this time, the liquid exerts a certain squeezing force on the cup body. The force is greatest in the direction perpendicular to the cup body and decreases towards both sides. In order to reduce the force at the connection between the pot body 1 and the heating plate 2, the connection between the pot body 1 and the heating plate 2 is not directly opposite the blade 6. Preferably, the connection between the pot body 1 and the heating plate 2 is higher than the blade 6. At the same time, when there are hard materials in the soy milk (such as stones accidentally put in), it reduces the possibility of stones hitting the glass pot body and improves the service life of the soy milk maker. Meanwhile, when the connection between the pot body 1 and the heating plate 2 is lower than or parallel to the blade 6, if the pulverization is not thorough, residue is likely to remain. The residue is easily squeezed into the gap at the connection between the pot body 1 and the heating plate 2 by the rotational force of the blade 6, making it difficult to clean. The above-mentioned position is a preferred position, but it does not mean that it cannot be set at a position lower than or parallel to the blade 6.

[0057] Furthermore, based on the above structure, the connection method between the connecting part 212 and the glass body 1 can be as follows: The first type, such as Figure 1 and Figure 2 As shown, the outer side wall of the lower part of the kettle body 1 is provided with an outwardly protruding step 11, and the top end of the connecting part 212 is curled and pressed against the step 11. The deformation of the circular rolled edge 213 structure on the heating plate 2 is used to press the glass kettle body 1, so that the glass kettle body 1 and the circular rolled edge 213 structure are interlocked. The sealing ring 4 on the end face forms a lasting pre-tightening force, ensuring the reliability of the side seal between the glass kettle body 1 and the heating plate 2.

[0058] This snap-fitting and riveting method can prevent the heating plate 2 and the glass body 1 from detaching, ensuring a reliable connection between the two. At the same time, this snap-fitting connection method reduces the direct overlap between the heating plate 2 and the glass body 1, thereby effectively increasing the visible space of the glass body 1 and making the entire cup more aesthetically pleasing.

[0059] Furthermore, the width of the step 11 is 0.5mm to 5mm. Preferably, it is 2mm, at which point the step 11 is not easily broken, and the fastening is secure and not easily loosened.

[0060] The second type involves a rotating buckle with opposing protrusions on the outer wall of the kettle body 1 and the inner wall of the heating plate 2. This buckle connects the heating plate 2 and the glass kettle body 1 as a single unit through rotation. The rotational torque creates a clamping force between the glass kettle body 1 and the heating plate 2, ensuring a secure connection and simultaneously tightening the sealing ring 4, preventing separation. For example, the lower outer wall of the kettle body 1 has a first protrusion, and the connecting part 212 has a second protrusion. The protrusion directions of the first and second protrusions are opposite. The first protrusion is an outward (away from the center of the kettle body 1) structure on the lower outer wall of the kettle body 1, and the second protrusion is an inward (towards the center of the kettle body 1) structure on the connecting part 212. Specifically, as follows: like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first protrusion is arranged at intervals on the outer side wall of the lower part of the kettle body 1 to form a swivel, and the second protrusion is arranged at intervals on the connecting part 212 of the heating plate 2 to form a protrusion 214 or a spiral arrangement to form a threaded protrusion 13. The first protrusion and the second protrusion are connected together.

[0061] For example, when the first protrusion is a snap fastener including a snap fastener platform 122, a snap fastener inclined surface 121, and a snap fastener stop rib 123, the second protrusion is a protrusion 214. When the connecting part 212 of the heating plate 2 is rotated and snapped onto the outer wall of the kettle body 1, the snap fastener inclined surface 121 can lift the heating plate 2, the snap fastener platform 122 is used to control the amount of compression, and after rotation into place, the snap fastener protrusion 214 is located on the snap fastener platform 122, and the snap fastener stop rib 123 is used to restrict the snap fastener protrusion 214 to prevent it from coming off when tightened in the forward direction. Preferably, the connecting part 212 is provided with 8 protrusions 214 and 8 snap fasteners.

[0062] Or, such as Figure 8 , Figure 9 and Figure 10 As shown, the first protrusion is spirally arranged on the outer side wall of the lower part of the kettle body 1 to form a threaded protrusion 13, and the second protrusion is spaced out on the connecting part 212 of the heating plate 2 to form protrusions 214 or spirally arranged to form a threaded protrusion 13. The first protrusion and the second protrusion are connected together.

[0063] For example, when the first protrusion is a threaded protrusion 13 and the second protrusion is a dot 214, the heating plate 2 is connected to the glass pot body 1 through the dot 214 and the threaded protrusion 13.

[0064] In addition to the connection methods mentioned above, there is a third type: the outer wall of the lower part of the pot body 1 is provided with an inwardly recessed mounting groove, and the connecting part 212 has a protruding point 214 that protrudes inward (towards the pot body 1), and the second protruding point 214 is embedded in the mounting groove for fixation.

[0065] Furthermore, based on the above solution of this embodiment, the top end of the connecting portion 212 extends outward to form a flange. Specifically, as follows: like Figure 4 As shown, the flange and the outer side of the connecting part 212 form a groove 215, and a bottom cover located below the cup body is also included. The outer edge of the bottom cover is embedded in the groove 215. The groove 215 and the upper edge of the bottom cover are fitted together for easy assembly. In addition, a decorative ring can be formed at the connection between the cup body 1 and the bottom cover to enhance the aesthetics. At this time, a stop structure can be provided on the outer side wall of the upper edge of the bottom cover to make the fit between the flange and the bottom cover more stable, and also improve the fit. Or, such as Figure 10 As shown, in order to prevent the heating plate 2 from scratching hands during installation or to facilitate the installation of the bottom cover, the flange is provided as a rolled edge 216.

[0066] Of course, in addition to the above-mentioned flange structure, the flange also includes a horizontal edge that extends only horizontally. In this case, the bottom cover can also be fitted. In an improved manner, a silicone pad or other structure can also be fitted on the above-mentioned flange.

[0067] Furthermore, to improve sealing performance and aesthetics. For example... Figure 2 As shown, the bottom surface and the supporting surface 211 are sealed together by an annular sealing ring 4. The supporting surface 211 is provided with an opening, and the sealing ring 4 is provided with a raised rib. The raised rib is embedded in the opening to prevent the sealing ring 4 from being misaligned during the installation of the glass pot body 1 and the heating plate 2, which would affect the sealing effect and aesthetics.

[0068] Or, such as Figure 4 As shown, the bottom surface of the kettle body 1 and the supporting surface 211 are sealed together by an annular sealing ring 4. The supporting surface 211 has a groove 215, and the sealing ring 4 is located within the groove 215. The groove 215 is located on the outer side of the supporting surface 211, and the inner end of the supporting surface 211 can fit tightly against the bottom surface of the kettle body 1 (with a small gap allowed), reducing the possibility of forming cleaning dead zones. Furthermore, the first protrusion can further press the sealing ring 4 firmly.

[0069] Example 6: Currently, the use of household food processors is becoming increasingly popular, such as soy milk makers and food processors. The cup body generally adopts an inner steel and outer plastic structure, and the water level line is printed in the stainless steel inner liner. It is impossible to make the water level line visible from the outside of the cup body. When the machine head is closed, the user cannot observe the entire process of making soy milk, which affects the user experience.

[0070] In addition, existing stainless steel heating cups conduct heat too quickly. During the heating of soy milk / rice paste, the temperature of the bottom and sides of the cup below the liquid surface and the side surface above the liquid surface rise rapidly. When boiling, a large amount of foam is produced. When the foam encounters the hot side surface of the cup above the liquid surface, it continues to expand and quickly overflows.

[0071] In existing technology, one approach is to replace the side wall of the cup with glass, with a hole at the bottom of the glass, and a bottom heating plate 2 installed at the hole. While this approach allows for visualization of the soy milk making process, the bottom heating plate 2 can easily lead to problems such as scorching at the bottom during the soy milk making process.

[0072] To solve the above technical problems, such as Figure 11 As shown, a food processing machine is proposed, including a cup body assembly and a cup lid disposed above the cup body assembly. The cup body assembly includes a glass body 1 that runs vertically through the body and a heating plate 2 that is connected to the lower part of the body 1. The lower part of the body 1 has a bottom surface, and the heating plate 2 has a support surface 211. The bottom surface and the support surface 211 are sealed together. The inner edge of the support surface 211 is recessed downward to form a receiving cavity. A heating element 3 is disposed on the outer surface of the receiving cavity. The outer edge of the support surface 211 extends upward to form a connecting part 212, and the connecting part 212 is connected to the outer side wall of the body 1.

[0073] Using the above technical solution, the cup assembly includes a separate glass body 1 and a metal heating plate 2. Glass has poor thermal conductivity, and during the heating process, heat from the metal heating plate 2 is not easily conducted to the glass body 1. Therefore, the temperature of the glass body 1 is relatively lower than that of the metal heating plate 2. When foam encounters the cooler side of the glass, it contracts, thus preventing overflow. Furthermore, stainless steel heating cups typically have a wall thickness of only 0.5mm. Due to this thin wall, the elastic modulus is low, and during pulping, the food processing machine blades 6 cause the material to impact the side wall of the cup, generating significant impact noise. When using the glass body 1, the relatively thicker glass has a higher elastic modulus, which reduces the noise generated by the material impacting the side wall. The thickness of the glass body 1 is between 2.5mm and 5mm, at which point the glass achieves a good noise reduction effect.

[0074] In this embodiment, the metal heating plate 2 is provided with a support surface 211. The bottom surface of the lower part of the glass (i.e., the bottom end face) cooperates with the support surface 211. A sealing ring 4 or sealant is provided between the support surface 211 and the bottom surface of the lower part of the glass to seal the heating plate 2 and the glass pot body 1. The outer edge of the heating plate 2 is connected to the outer side wall of the pot body 1. At this time, it is not necessary to consider the size of the upper and lower mounting openings of the glass pot body 1, which facilitates the design of the pot body 1 and the installation of the heating plate 2 and the pot body 1. On the other hand, it is more conducive to improving the sealing effect of the heating plate 2 and the bottom surface of the pot body 1 in the horizontal direction. The inner edge of the support surface 211 extends downward to form a bowl-shaped receiving cavity. The support surface 211 is sealed to the bottom surface of the glass pot body 1. The inner wall of the pot body 1 extends longitudinally to the inner wall of the receiving cavity. The end-face sealing ensures that residues such as soy milk or food scraps will not enter the joint between the bottom surface of the glass and the support surface 211, preventing residue buildup and facilitating cleaning. This solves the problem of forming cleaning dead corners. The bowl shape can include side walls and a bottom wall, or it can be spherical.

[0075] In summary, the heating plate 2 is bowl-shaped, and the heating element 3 is located on the outer side of the heating plate 2. This forms a cavity for the heated liquid without affecting the heating rate. Furthermore, it prevents scorching and water stains or scale buildup during dry heating. Specifically, the heating plate 2 has a horizontal support surface 211 that seals against the bottom surface of the kettle body 1. One end of the support surface 211 extends to connect with the outer side of the kettle body 1, and the other end extends to form a cavity. The heating element 3 is located on the side wall of this cavity. This design solves both the installation problems of the heating plate 2 and the kettle body 1, as well as the problem of dirt and grime accumulation. It also allows for changes in the installation position of the heating element 3, thus resolving the issues of scorching and water stains or scale buildup.

[0076] Furthermore, in order to improve the heating effect of the area heated by heating element 3, and at the same time achieve a better anti-overflow effect for the cup body, such as... Figure 11 As shown, the ratio of the height H1 of the receiving cavity to the height H3 of the glass pot body 1 ranges from 1 to 15, and the height H1 of the receiving cavity is greater than 8 mm. Preferably, the ratio is 5, and H1 is 15-20 mm. Furthermore, such as Figure 12As shown, the cup assembly also includes a pulverizing structure, which includes a blade 6. The blade 6 can be fixed to the bottom of the heating plate 2 or connected to the cup lid. The distance from the blade 6 to the bottom of the receiving cavity is H2, and the height of the receiving cavity is H1. H1 is greater than H2, and H1-H2 ≥ 3mm, preferably greater than 5mm and less than 10mm. During the pulping process of the food processor, the motor drives the blade 6 to rotate at high speed. At this time, the liquid exerts a certain squeezing force on the cup body. The force is greatest in the direction perpendicular to the cup body and decreases to both sides. In order to reduce the force at the connection between the pot body 1 and the heating plate 2, the connection between the pot body 1 and the heating plate 2 is not directly opposite the blade 6. Preferably, the connection between the pot body 1 and the heating plate 2 is higher than the blade 6. At the same time, when there are hard materials in the bean material (such as stones accidentally put in), the possibility of stones hitting the glass pot body is reduced, thus improving the service life of the food processor. Meanwhile, if the connection between the kettle body 1 and the heating plate 2 is lower than or parallel to the blade 6, and the pulverization is not thorough enough, residue may remain. This residue can easily be squeezed into the gap between the kettle body 1 and the heating plate 2 by the rotational force of the blade 6, making it difficult to clean. The above arrangement is a preferred position, but it does not mean that it cannot be set at a position lower than or parallel to the blade 6.

[0077] Furthermore, based on the above structure, the connection method between the connecting part 212 and the glass body 1 can be as follows: The first type, such as Figure 1 and Figure 2 As shown, the outer side wall of the lower part of the kettle body 1 is provided with an outwardly protruding step 11, and the top end of the connecting part 212 is curled and pressed against the step 11. The deformation of the circular rolled edge 213 structure on the heating plate 2 is used to press the glass kettle body 1, so that the glass kettle body 1 and the circular rolled edge 213 structure are interlocked. The sealing ring 4 on the end face forms a lasting pre-tightening force, ensuring the reliability of the side seal between the glass kettle body 1 and the heating plate 2.

[0078] This snap-fitting and riveting method can prevent the heating plate 2 and the glass body 1 from detaching, ensuring a reliable connection between the two. At the same time, this snap-fitting connection method reduces the direct overlap between the heating plate 2 and the glass body 1, thereby effectively increasing the visible space of the glass body 1 and making the entire cup more aesthetically pleasing.

[0079] Furthermore, the width of the step 11 is 0.5mm to 5mm. Preferably, it is 2mm, at which point the step 11 is not easily broken, and the fastening is secure and not easily loosened.

[0080] The second type involves a rotating buckle with opposing protrusions on the outer wall of the kettle body 1 and the inner wall of the heating plate 2. This buckle connects the heating plate 2 and the glass kettle body 1 as a single unit through rotation. The rotational torque creates a clamping force between the glass kettle body 1 and the heating plate 2, ensuring a secure connection and simultaneously tightening the sealing ring 4, preventing separation. For example, the lower outer wall of the kettle body 1 has a first protrusion, and the connecting part 212 has a second protrusion. The protrusion directions of the first and second protrusions are opposite. The first protrusion is an outward (away from the center of the kettle body 1) structure on the lower outer wall of the kettle body 1, and the second protrusion is an inward (towards the center of the kettle body 1) structure on the connecting part 212. Specifically, as follows: like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first protrusion is arranged at intervals on the outer side wall of the lower part of the kettle body 1 to form a swivel 12, and the second protrusion is arranged at intervals on the connecting part 212 of the heating plate 2 to form a protrusion 214 or a spiral arrangement to form a threaded protrusion 13. The first protrusion and the second protrusion are connected together.

[0081] For example, when the first protrusion is a buckle 12 including a buckle platform 122, a buckle ramp 121, and a buckle stop rib 123, the second protrusion is a protrusion 214. When the connecting part 212 of the heating plate 2 is rotated and snapped onto the outer wall of the kettle body 1, the buckle ramp 121 can lift the heating plate 2, the buckle platform 122 is used to control the amount of compression, and after rotation into place, the snap-fit ​​protrusion 214 is located on the buckle platform 122. The buckle stop rib 123 is used to restrict the snap-fit ​​protrusion 214 and prevent it from coming off when it is tightened in the forward direction. Preferably, the connecting part 212 is provided with 8 protrusions 214 and 8 buckles.

[0082] Or, such as Figure 8 , Figure 9 and Figure 10 As shown, the first protrusion is spirally arranged on the outer side wall of the lower part of the kettle body 1 to form a threaded protrusion 13, and the second protrusion is spaced out on the connecting part 212 of the heating plate 2 to form protrusions 214 or spirally arranged to form a threaded protrusion 13. The first protrusion and the second protrusion are connected together.

[0083] For example, when the first protrusion is a threaded protrusion 13 and the second protrusion is a dot 214, the heating plate 2 is connected to the glass pot body 1 through the dot 214 and the threaded protrusion 13.

[0084] In addition to the connection methods mentioned above, there is a third type: the outer wall of the lower part of the pot body 1 is provided with an inwardly recessed mounting groove, and the connecting part 212 has a protruding point 214 that protrudes inward (towards the pot body 1), and the second protruding point 214 is embedded in the mounting groove for fixation.

[0085] Furthermore, based on the above solution of this embodiment, the top end of the connecting portion 212 extends outward to form a flange. Specifically: like Figure 4 As shown, the flange and the outer side of the connecting part 212 form a groove 215, and a bottom cover located below the cup body is also included. The outer edge of the bottom cover is embedded in the groove 215. The groove 215 and the upper edge of the bottom cover are fitted together for easy assembly. In addition, a decorative ring can be formed at the connection between the cup body 1 and the bottom cover to enhance the aesthetics. At this time, a stop structure can be provided on the outer side wall of the upper edge of the bottom cover to make the fit between the flange and the bottom cover more stable, and also improve the fit. Or, such as Figure 10 As shown, in order to prevent the heating plate 2 from scratching hands during installation or to facilitate the installation of the bottom cover, the flange is provided as a rolled edge 216.

[0086] Of course, in addition to the above-mentioned flange structure, the flange also includes a horizontal edge that extends only horizontally. In this case, the bottom cover can also be fitted. In an improved manner, a silicone pad or other structure can also be fitted on the above-mentioned flange.

[0087] Furthermore, to improve sealing performance and aesthetics. For example... Figure 2 As shown, the bottom surface and the supporting surface 211 are sealed together by an annular sealing ring 4. The supporting surface 211 is provided with an opening, and the sealing ring 4 is provided with a raised rib. The raised rib is embedded in the opening to prevent the sealing ring 4 from being misaligned during the installation of the glass pot body 1 and the heating plate 2, which would affect the sealing effect and aesthetics.

[0088] Or, such as Figure 4 As shown, the bottom surface of the kettle body 1 and the supporting surface 211 are sealed together by an annular sealing ring 4. The supporting surface 211 has a groove 215, and the sealing ring 4 is located within the groove 215. The groove 215 is located on the outer side of the supporting surface 211, and the inner end of the supporting surface 211 can fit tightly against the bottom surface of the kettle body 1 (with a small gap allowed), reducing the possibility of forming cleaning dead zones. Furthermore, the first protrusion can further press the sealing ring 4 firmly.

[0089] The cup body assemblies of embodiments one to five described above are used in electric kettles. In addition, the cup body assembly may also include an outer shell, which is wrapped around the outside of the cup body, and may completely or partially wrap around it.
