Description

A food processing machine Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a food processing machine. Background Technology

[0002] Existing food processors (soy milk makers, blenders, health pots, etc.) typically have a handle on the outside of the casing, a Hall effect switch inside the handle, a circuit board connected to the Hall effect switch inside the casing, a motor, and a power board inside the casing. The power board is horizontally positioned below the motor, and the circuit board is located to one side of the motor and inside the handle cover (e.g., the food processor disclosed in CN201921650386.5). In this structure, because the power board is horizontally positioned below the motor, it occupies space in the height direction of the casing, resulting in a relatively large overall machine height and causing vibration during operation. Furthermore, since the circuit board and handle are both located on one side of the motor, the space on the other side of the motor is unused, leading to low overall space utilization and an uncompacted structural layout. This structure also causes the machine's center of gravity to deviate from the motor's axis, resulting in poor balance and an unstable working environment for the motor, making the entire machine prone to vibration. Summary of the Invention

[0003] This application provides a food processing machine to solve the problems of unreasonable space utilization, insufficient structural layout, poor overall balance and vibration caused by the circuit board and handle being located on one side of the motor in existing food processing machines.

[0004] This application provides a food processing machine, including a base and a housing mounted on the base. The housing contains an inner cup, a motor, a motor cover, a power board, a control board, and a socket. The side wall of the housing has an operating interface. The control board is mounted inside the housing and corresponds to the operating interface. The motor cover has a cavity for accommodating the motor. The motor shaft extends into the inner cup and is connected to a pulverizing blade. The outer wall of the motor cover has an outwardly protruding portion. The protruding portion has an air inlet channel communicating with the cavity. The power board, the control board, and the socket are arranged circumferentially around the motor cover, with the power board opposite to the protruding portion. The control board and the socket are located on opposite sides of the protruding portion.

[0005] Compared to existing technologies where the circuit board and handle are located on one side of the motor, resulting in poor overall balance, this application utilizes a more compact structure with the power board, control board, socket, and protrusion arranged around the circumference of the motor cover. This makes more efficient use of the internal space, and the center of gravity of the machine does not deviate from the motor axis, resulting in better overall balance and less vibration during operation. Furthermore, by placing the power board around the circumference of the motor cover rather than at the bottom, this application effectively reduces the overall height of the machine, thus avoiding vibration problems caused by excessive height.

[0006] As a preferred technical solution, the outer wall of the housing away from the power board is provided with a handle, and a switch is provided inside the handle. The wire of the switch extends to the bottom of the inner cup and is constrained by the outer peripheral wall of the motor cover, so that the wire is wound around the outer peripheral wall of the motor cover to be electrically connected to the power board.

[0007] By extending the wire to the bottom of the inner cup and constraining it by the outer peripheral wall of the motor cover, the wire can be wound around the outer peripheral wall of the motor cover to connect with the power board. This allows the wire to avoid the heating element and effectively solves the problem of wire damage caused by contact between the switch wire and the heating element of the food processor.

[0008] As a preferred technical solution, the outer peripheral wall of the motor cover is provided with a plurality of hooks spaced apart along the circumferential direction, and the wire is constrained by the hooks and wound around the outer peripheral wall of the motor cover to be electrically connected to the power board.

[0009] Alternatively, the outer peripheral wall of the motor cover is provided with a wire-holding groove extending to the power board in the circumferential direction, and the wire extends along the wire-holding groove to be electrically connected to the power board.

[0010] Using clips or slots to constrain wires can prevent wires from being damaged by contact with other components due to lack of constraint. It also optimizes the layout of the wires, ensuring that all wires are on the preset wiring path, and preventing problems such as messy or damaged wire layout.

[0011] As a preferred technical solution, a sandwich is formed between the inner cup and the outer shell, and the wire passes through the outer shell and extends along the sandwich to the bottom of the inner cup.

[0012] By using the interlayer between the inner cup and the outer shell as a wiring channel for the wires, the space between the inner cup and the outer shell is utilized in a reasonable way, and the wires are protected by the inner cup and the outer shell to avoid damage.

[0013] As a preferred technical solution, the handle is provided with a wiring groove that extends longitudinally to the bottom of the handle. The outer casing is provided with a wire hole corresponding to the bottom position of the handle. The wire of the switch extends along the wiring groove, enters the wire hole, and is electrically connected to the power board.

[0014] As another wiring method, wiring the wires through the cable trays in the handle is beneficial for wire management and installation, and can also prevent the wires from being damaged.

[0015] As a preferred technical solution, the bottom of the inner cup is provided with a heating tube, and the food processing machine also includes an isolation plate, which is disposed between the heating tube and the motor cover, and the isolation plate extends upward in the circumferential direction with an annular rim, which is used to isolate the heating tube and the wire.

[0016] The heating element and the wire are isolated by the ring-shaped rim on the isolation plate, which further prevents the wire from being damaged by the heating element and ensures the safety of the wire in use.

[0017] As a preferred technical solution, the power board is installed on the outer wall of the motor cover, so that the inner cup, the motor cover, the motor, and the power board form a crushing assembly.

[0018] By mounting the power board on the outer wall of the motor housing, the inner cup, motor housing, motor, and power board form an integrated crushing assembly. This makes the overall structure of the food processor more compact, requiring less installation space inside the casing, and the compact structure also reduces vibration generated during motor operation. Furthermore, the integrated crushing assembly makes the food processor easier to assemble, effectively improving assembly efficiency.

[0019] As a preferred technical solution, the bottom of the inner cup is provided with a heating tube, and the food processing machine also includes an isolation plate. The isolation plate is disposed between the heating tube and the motor cover. The isolation plate extends to the upper opening of the air inlet channel and surrounds the motor cover to form a connecting channel. The connecting channel connects the air inlet channel with the receiving cavity.

[0020] As a preferred technical solution, the isolation plate is fixed to the bottom of the inner cup and the top of the motor cover by screws.

[0021] The motor cover is installed relative to the inner cup through the isolation plate, and the isolation plate can achieve thermal isolation between the inner cup and the motor.

[0022] As a preferred technical solution, the inner side of the base is provided with an upwardly raised first bulge, and the inner side of the first bulge is provided with a through air duct. The lower end of the air duct extends from the bottom wall of the base to the side wall of the base to form an air inlet, and the upper end of the air duct is connected to the lower opening of the air inlet channel.

[0023] As a preferred technical solution, the food processing machine further includes a volute, which, together with the base, forms a top-opening air-gathering cavity. A fan is installed inside the air-gathering cavity, and the air-gathering cavity is connected to the receiving cavity through the top opening. The air-gathering cavity also includes a spiral-shaped air outlet channel, which is connected to an air outlet disposed on the base.

[0024] By forming an air-gathering cavity between the volute and the base, and installing a fan inside the air-gathering cavity, the air that has cooled the motor can be quickly discharged from the food processor, so as to avoid the hot air generated affecting the components inside the casing.

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0045] This application provides a food processing machine, wherein Figure 1 is an exploded view of the food processing machine according to this application embodiment, Figure 2 is a cross-sectional view of the food processing machine according to this application embodiment, Figure 3 is an exploded view of the food processing machine after the outer shell 2 is hidden, and Figure 4 is a structural diagram of the food processing machine with the air outlet 12 shown. As shown in Figures 1-4, the food processing machine includes a base 1, an outer shell 2, an inner cup 3, a motor cover 4, a motor 5, a power board 6, a control board 7, an isolation plate 8, a volute 9, a cup lid 10, and a socket 20, wherein: the outer shell 2 is mounted on the base 1, the inner cup 3, the motor cover 4, the motor 5, the power board 6, the control board 7, the isolation plate 8, and the volute 9 are all placed inside the outer shell 2, the cup lid 10 is fastened to the top opening of the outer shell 2, and the socket 20 is mounted on the outer shell 2.

[0046] A handle 30 is installed on the outer periphery of the outer casing 2. A switch 40, electrically connected to the power board 6, is located inside the handle 30. A lid-closing trigger rod and an anti-overflow electrode 101 are located inside the lid 10. When the lid 10 rotates relative to the outer casing 2 to a preset position, the lid-closing trigger rod on the lid 10 is electrically connected to the switch 40 to detect lid closure. The food processor can only be started after the lid is fully closed. It is understood that the switch 40 inside the handle 30 can also be installed on other components such as the outer casing 2, as long as it can detect lid closure when the lid 10 is closed. The anti-overflow electrode 101 is also electrically connected to the switch 40. When the liquid in the inner cup 3 exceeds a preset level and contacts the anti-overflow electrode 101, an anti-overflow signal is generated to adjust the operating strategy of the food processor for better processing of the ingredients.

[0047] In this embodiment of the application, as shown in FIG3, a heating tube 31 is provided at the bottom of the inner cup 3. The heating tube 31 can heat the food inside the inner cup 3 to meet the processing requirements. The heating tube 31, the isolation plate 8, and the motor cover 4 are arranged sequentially from top to bottom. The isolation plate 8 can isolate the heating tube 31 from the motor cover 4, thereby isolating the heating tube 31 from the motor 5, so as to prevent the heat of the heating tube 31 from being transferred to the motor cover 4 and causing heat damage to the motor 5 and other electronic components inside the motor cover 4. Optionally, the heating tube 31 has a C-shaped structure. The opening of the C-shaped structure (i.e., the wiring terminal) and the anti-overflow electrode 101 on the cup lid 10 are located on both sides of the axis of the inner cup 3, so that the anti-overflow electrode 101 is located above the heating part of the heating tube 31, ensuring that the anti-overflow electrode 101 can touch the foam first when the slurry is cooked, thereby achieving the anti-overflow effect.

[0048] Figure 5 is a schematic diagram of the structure of the motor cover 4 according to an embodiment of this application. As shown in Figure 5, the motor cover 4 is a cover structure with openings at both the top and bottom, forming a receiving cavity for accommodating the motor 5. The isolation plate 8 is located at the top opening of the motor cover 4 (as shown in Figure 3). After the motor shaft of the motor 5 passes through the isolation plate 8, it seals and extends into the inner cup 3 and is connected to the pulverizing blade inside the inner cup 3, so as to drive the pulverizing blade to rotate and pulverize the food.

[0049] In this embodiment, as shown in FIG6, FIG6 is an enlarged schematic diagram of point A in FIG3 of this application embodiment. In this embodiment, an outwardly protruding part 41 is provided on the outer wall of the motor cover 4. The protruding part 41 is provided with an air inlet channel 42 communicating with the receiving cavity. The air inlet channel 42 is independent of the receiving cavity (optionally, as shown in FIG6, the air inlet channel 42 and the receiving cavity are arranged in a left-right distribution). For example, the motor cover 4 may include a body 43 and the above-mentioned protruding part 41. The receiving cavity is disposed in the body 43. The protruding part 41 and the body 43 can be integrally formed by injection molding. On the one hand, it can ensure the sealing of the air inlet channel 42, and on the other hand, it can facilitate the processing of the motor cover 4.

[0050] The lower opening 422 of the aforementioned air inlet channel 42 is connected to an air inlet 11. For example, an air inlet 11 can be provided on the base 1. Outside air can enter the air inlet channel 42 through the air inlet 11, and then enter the receiving cavity through the air inlet channel 42 to dissipate heat from the motor 5 in the receiving cavity.

[0051] It should be noted that one side of the aforementioned isolation plate 8 extends above the upper opening 421 of the air inlet channel 42 and forms a connecting channel 50 with the motor cover 4. This connecting channel 50 connects the air inlet channel 42 and the receiving cavity to enable the air in the air inlet channel 42 to flow into the receiving cavity.

[0052] In this embodiment, an air outlet 12 is also provided on the base 1. The air outlet 12 is connected to the receiving cavity so that the air after cooling the motor 5 can flow out of the base 1. By setting an air flow path of air inlet 11-air inlet channel 42-connecting channel 50-receiving cavity-air outlet 12, this embodiment can achieve independent cooling of the motor 5. Compared with the prior art, where air needs to circulate inside the outer casing 2 for a period of time before cooling the motor 5, the cooling efficiency of this embodiment is higher. Moreover, through the above-mentioned air flow path, the outside air directly cools the motor 5 without absorbing heat from other heat sources, resulting in a better cooling effect on the motor 5.

[0053] As shown in Figure 6, the air inlet channel 42 of this embodiment includes an upper opening 421, a lower opening 422, and a contraction section 423 located between the upper opening 421 and the lower opening 422. The contraction section 423 is constricted relative to the lower opening 422. By setting the contraction section 423, the cross-section of the air inlet channel 42 exhibits a distribution pattern of first large and then small from bottom to top. This increases the air velocity flowing through the contraction section 423, thereby increasing the air velocity flowing to the motor 5 through the Laval principle and enhancing the heat dissipation effect on the motor 5. Preferably, the opening area of ​​the lower opening 422 is larger than the opening area of ​​the upper opening 421, and the contraction section 423 is located in the middle of the air inlet channel 42. By making the opening area of ​​the lower opening 422 larger than the opening area of ​​the upper opening 421, the air inlet area can be increased, thereby increasing the air volume. At the same time, in conjunction with the contraction section 423, the air velocity and air volume delivered to the motor 5 can be further increased, improving the heat dissipation effect.

[0054] Considering that the existing air inlet 11 located at the bottom of the base 1 is close to the table surface, which affects air intake and allows water stains or dust to easily enter, this application embodiment further improves the structure of the air inlet 11. As shown in Figures 7-10, where Figure 7 is an enlarged view of section B in Figure 3 of this application embodiment, Figure 8 is an enlarged view of section C in Figure 2 of this application embodiment, Figure 9 is a schematic diagram of the assembly structure of the volute 9 and the base 1 of this application embodiment, and Figure 10 is a schematic diagram of the structure of the base 1 of this application embodiment. In this embodiment, a first raised portion 13 is provided on the inner side of the base 1, and a through air duct 131 is provided on the inner side of the first raised portion 13. The lower end of the air duct 131 extends from the bottom wall of the base 1 to the side wall of the base 1 to form the air inlet 11, and the upper end of the air duct 131 is connected to the lower opening 422 of the air intake channel 42.

[0055] Through the above structure, the air duct 131 is provided with a certain height, which can effectively prevent water stains or dust from entering the air intake channel 42 and the receiving cavity with the outside air, thus avoiding damage to the motor 5. Moreover, the air inlet 11 extends from the bottom wall of the base 1 to the side wall of the base 1. When the food processor is placed on the countertop, the air inlet 11 will not be completely blocked by the countertop, thus ensuring that the air inlet 11 is directly connected to the outside and will not affect the air intake. Furthermore, the setting of the air inlet 11 means that even if the food processor is placed in a corner, there will be a gap between the air inlet 11 and the corner, which will still not affect the air intake. Preferably, the air inlet 11 is located in the transition area formed between the bottom wall and the side wall of the base 1. This transition area can be an arc-shaped structure for better air intake.

[0056] As shown in Figure 9, the upper port of the first raised portion 13 is an array of multiple first connecting holes 132. By setting multiple first connecting holes 132, airflow can smoothly enter the air intake channel 42 through the first connecting holes 132 to dissipate heat from the motor 5, ensuring the heat dissipation effect of the motor 5. In addition, the setting of multiple first connecting holes 132 can also greatly reduce noise generation and improve the user experience. Furthermore, the small diameter of the first connecting holes 132 can also prevent large particles of dirt from entering the air intake channel 42, affecting heat dissipation and causing damage to the motor 5.

[0057] Optionally, as shown in Figures 9 and 10, this embodiment has an upwardly raised second protrusion 14 on the inner side of the base 1. The second protrusion 14 has a plurality of arrayed second connecting holes 141, which together form an air outlet 12. By providing the second connecting holes 141 on the second protrusion 14 to form the air outlet 12, water stains or dust can be prevented from entering the base 1 through the air outlet 12. Moreover, when the food processor is placed on the countertop, there is a certain space between the air outlet 12 and the countertop, which can ensure that air can be smoothly discharged from the air outlet 12.

[0058] In this embodiment, referring to Figures 3, 9, and 11, the food processing machine further includes a volute 9, which is disposed between the motor cover 4 and the base 1 and is connected to the base 1. If the base 1 has a cavity structure of a certain depth, the volute 9 can be accommodated within this cavity structure. The volute 9 and the base 1 together form a top-opening air-gathering cavity 60, which communicates with the accommodating cavity through the top opening. The air-gathering cavity 60 also includes a spiral-shaped air outlet channel, which communicates with the air outlet 12. Air entering the accommodating cavity via the air inlet channel 42 and the connecting channel 50 dissipates heat from the motor 5, then enters the air outlet channel and is finally discharged through the air outlet 12.

[0059] Preferably, a fan 70 is provided inside the aforementioned air-gathering cavity 60. The fan 70 can quickly expel the air cooled by the motor 5, preventing the generated hot air from affecting the components inside the housing 2. It should be noted that the fan 70 can be driven to rotate by the motor 5, i.e., both ends of the motor 5 are provided with output shafts, and the lower output shaft of the motor 5 is connected to the fan 70. The fan 70 can also be controlled independently, i.e., driven to rotate independently by a drive component.

[0060] In this embodiment, as shown in FIG12, the isolation plate 8 extends upward in the circumferential direction with an annular rim 81. The annular rim 81 is used to isolate the heating tube 31 and the wire 401 of the switch 40 to avoid the wire 401 being damaged by the heating tube 31 and to ensure the safe use of the wire 401.

[0061] The isolation plate 8 is fixed to the bottom of the inner cup 3 and the top of the motor cover 4 by screws. For example, screw holes can be provided at the bottom of the inner cup 3 and the top of the motor cover 4, and through holes can be provided on the isolation plate 8. Bolts pass through the through holes and are threadedly connected to the screw holes to fix the isolation plate 8 to the inner cup 3 and the motor cover 4.

[0062] Considering the existing food processing machines, the circuit board and handle 30 are located on one side of the motor 5, and no components are set in the space on the other side of the motor 5. This results in low overall space utilization of the food processing machine, an insufficiently compact structural layout, and the structure causes the center of gravity of the whole machine to deviate, leading to poor balance of the whole machine. The working environment of the motor 5 is unstable and prone to vibration.

[0063] To address the aforementioned issues, as shown in Figure 13, which is a schematic diagram illustrating the distribution of the power board 6, control board 7, socket 20, and protrusion 41 in an embodiment of this application, the power board 6, control board 7, and socket 20 of the food processor of this application are arranged circumferentially around the motor cover 4, with the power board 6 positioned opposite the protrusion 41, and the control board 7 and socket 20 located on opposite sides of the protrusion 41. This structural arrangement makes the food processor's structure more compact, optimizes the use of internal space, and ensures the machine's center of gravity does not deviate from the axis of the motor 5, resulting in better overall balance and reduced vibration during operation. Furthermore, by placing the power board 6 circumferentially rather than at the bottom of the motor cover 4, the overall height of the machine is effectively reduced, thus avoiding vibration problems caused by excessive machine height.

[0064] In this embodiment, an operation interface 21 is provided on the side wall of the outer casing 2. The control board 7 is installed inside the outer casing 2 and corresponds to the operation interface 21 and is electrically connected to the power board 6. For example, a spring button (not shown in the figure) can be provided on the control board 7. The spring button is provided corresponding to the operation interface 21, and the free end of the spring button needs to be in contact with the operation interface 21. When the user touches the operation interface 21, the spring button can be triggered, thereby causing the control board 7 to generate relevant command signals, and cooperate with the power board 6 to control the various functional components of the food processing machine.

[0065] More preferably, in this embodiment, the handle 30 is located on the side near the protrusion 41 of the motor cover 4 and opposite to the power board 6. That is, the handle 30 is located on the side of the outer casing 2 away from the power board 6. As shown in FIG14, the wire 401 of the switch 40 inside the handle 30 extends to the bottom of the inner cup 3 and is constrained by the outer peripheral wall of the motor cover 4, so that the wire 401 is wound around the outer peripheral wall of the motor cover 4 to make electrical connection with the power board 6. The above-mentioned arrangement of the wire 401 can make the wire 401 avoid the heating component, effectively solving the problem of damage to the wire 401 caused by contact between the wire 401 of the switch 40 and the heating component of the food processor.

[0066] For example, in this embodiment, the above-mentioned wire 401 extends to the bottom of the inner cup 3 in at least two ways: First, a sandwich layer is formed between the inner cup 3 and the outer shell 2, and the wire 401 passes through the outer shell 2 and extends along the sandwich layer to the bottom of the inner cup 3. That is, the sandwich layer can be used as a wiring channel for the wire 401, and the wire 401 extends downward from inside the sandwich layer. On the one hand, it makes reasonable use of the space between the inner cup 3 and the outer shell 2, and on the other hand, it can protect the wire 401 from damage by the inner cup 3 and the outer shell 2. Second, a wiring groove can be provided in the handle 30, which extends longitudinally to the bottom of the handle 30. The outer shell 2 has a wire hole at the bottom position of the handle 30. The wire 401 of the switch 40 extends along the wiring groove, enters the wire hole, and is electrically connected to the power board 6. That is, in this way, the handle 30 provides a wiring channel (i.e., wiring groove) for the wire 401, which can also realize the wiring and protection of the wire 401.

[0067] Preferably, in this embodiment, the method of "wire 401 winding around the outer peripheral wall of motor cover 4" can be achieved by setting multiple hooks at intervals along the circumferential direction on the outer peripheral wall of motor cover 4. The wire 401, constrained by the hooks, winds around the outer peripheral wall of motor cover 4 until it connects to the power board 6. In this case, the hooks can be set on the protrusion 41 or on the side wall of motor cover 4 adjacent to the protrusion 41. Alternatively, in this embodiment, the method of "wire 401 winding around the outer peripheral wall of motor cover 4" can also be achieved by setting a wire-holding groove along the circumferential direction on the outer peripheral wall of motor cover 4, extending to the power board 6. The wire 401 extends along the wire-holding groove until it connects to the power board 6. That is, the wire 401 is gathered and constrained by the wire-holding groove. Using hooks or wire-holding grooves to constrain the wire 401 avoids damage to other components due to lack of constraint, and optimizes the layout of the wire 401, ensuring that the entire wire 401 is on a preset wiring path, preventing the wire 401 from becoming disordered or damaged.

[0068] In this embodiment, the power board 6 is mounted on the outer wall of the motor cover 4, so that the inner cup 3, the motor cover 4, the motor 5, and the power board 6 form an integrated crushing assembly. On the one hand, this makes the overall structure of the food processor more compact, requires less installation space inside the outer shell 2, and the compact structure can also reduce the vibration generated during the operation of the motor 5. On the other hand, the integrated crushing assembly also makes the assembly of the food processor more convenient and effectively improves the assembly efficiency.

[0069] Furthermore, in this embodiment, the control panel 7 and socket 20 are respectively located on opposite sides of the handle 30, and the control panel 7 can be positioned on the side of the food processor facing the user during use.
