Description

Technical Field

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

[0002] With the development of soymilk maker technology, users' requirements for using soymilk makers are also gradually increasing. Currently, the motor of existing soymilk makers is located at the bottom of the outer casing, and the output end connects to the grinding blade through the cup assembly. Currently, the motor's heat dissipation is usually achieved by setting air inlets and outlets at the bottom of the outer casing. Cold air from the outside enters the casing through the air inlet and circulates inside for a period of time before reaching the motor for heat dissipation, resulting in relatively low heat dissipation efficiency for the motor.

[0003] To address the aforementioned issues, prior art CN201710720155.6 discloses a split-type blender. This blender includes a frame, a motor located within the frame, and an air duct unit disposed within the frame. The frame supports the inner cup, and the motor's output is connected to the inner cup via a coupling. While this structure achieves rapid heat dissipation for the motor through the air duct unit, the split-type design requires a large internal space due to the frame supporting the inner cup and the internal placement of components such as the motor, motor cover, and air duct unit. This results in a large overall frame size and a less compact overall blender structure. Furthermore, the split-type design, requiring the motor to be connected to the inner cup via a coupling, causes vibration during motor operation, further impacting the overall structural compactness of the blender. Utility Model Content

[0004] This application provides a soymilk maker that addresses the technical problem of how to make the overall structure of the soymilk maker more compact, given that the inner cup and motor are installed together in existing soymilk makers and the motor requires heat insulation and heat dissipation.

[0005] This application provides a soymilk maker, including a base with a housing mounted on it. Inside the housing are an inner cup, a partition plate, a motor cover, a motor, and a power board. A heating element is located at the bottom of the inner cup. The partition plate is positioned below the heating element and isolates it from the motor cover. The partition plate and the motor cover together form a cavity for accommodating the motor. The motor shaft passes through the partition plate, extends into the inner cup, and is connected to a grinding blade. The side wall of the motor cover has an air guide channel located on one side of the cavity and independent of the cavity. The partition plate extends to the upper opening of the air guide channel and forms a connecting channel with the motor cover, connecting the air guide channel to the cavity. The base has an air inlet communicating with the lower opening of the air guide channel and an air outlet communicating with the cavity. The power board is mounted on the outside of the motor cover, so that the inner cup, the partition plate, the motor cover, the motor, and the power board form a grinding assembly.

[0006] Compared to existing split-type blenders, the motor shaft of this application extends into the inner cup through the partition plate and is connected to the inner cup. By providing an air duct connecting the receiving cavity and isolating the heating element from the motor cover through the partition plate, heat dissipation and insulation of the motor are achieved. Furthermore, this application mounts the power board on the outside of the motor cover, making the inner cup, partition plate, motor cover, motor, and power board a single integrated grinding assembly. On one hand, compared to the split-type blender structure, this application forms a single integrated grinding assembly within the outer shell, making the overall structure of the soymilk maker more compact, requiring less internal installation space, and resulting in a smaller soymilk maker. On the other hand, the integrated grinding assembly, while making the soymilk maker more compact, also reduces vibration generated during motor operation. In addition, the integrated grinding assembly facilitates assembly and effectively improves assembly efficiency.

[0007] Furthermore, compared to the existing technology where the power board is horizontally positioned inside the base, this application mounts the power board on the outside of the motor cover, which can also prevent water droplets from damaging the power board.

[0008] As a preferred technical solution, the air guide channel includes a contraction section disposed between the upper opening and the lower opening, the contraction section being contracted relative to the lower opening.

[0009] By setting up a contraction section, the airflow velocity through the contraction section can be increased, which increases the airflow velocity to the motor through the Laval principle, thus enhancing the heat dissipation effect on the motor.

[0010] As a preferred technical solution, the opening area of ​​the lower opening is larger than the opening area of ​​the upper opening, and the contraction section is located in the middle of the air guide channel.

[0011] By having a larger opening area at the bottom than at the top, this application increases the air intake area compared to a duct structure with the same opening area at both ends. This increases the air intake volume, and when combined with the contraction section, it further increases the air velocity and volume delivered to the motor, thus improving the heat dissipation effect.

[0012] 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 inlet channel. The lower end of the air inlet channel extends from the bottom wall of the base to the side wall of the base to form the air inlet, and the upper end of the air inlet channel is connected to the lower opening.

[0013] Compared to structures where the air inlet is located at the bottom of the base, this application uses an upward-curving base to form a first raised section. This first raised section houses a through-flow air inlet channel, which has a certain height to effectively prevent water stains or dust from entering the air guide channel and housing cavity with outside air, thus avoiding damage to the motor. Furthermore, the air inlet extends from the bottom wall of the base to the side wall, ensuring that it is not completely obstructed when the soymilk maker is placed on a countertop, thus guaranteeing unobstructed airflow. Even when the soymilk maker is placed in a corner, the air inlet will have a gap with the corner, ensuring uninterrupted airflow.

[0014] As a preferred technical solution, the upper port of the first raised portion is inserted into the lower opening of the air guide channel.

[0015] By interlocking the two parts, it is beneficial to assemble and position the air guide channel of the motor cover with the first raised part. On the other hand, it is also convenient to seal the first raised part and the air guide channel. For example, a sealing ring can be set between the two parts to achieve a sealed connection between the air guide channel and the air inlet channel.

[0016] And / or, the upper port of the first raised portion is a plurality of first connecting holes of the array.

[0017] By setting multiple first connecting holes, airflow can smoothly enter the air guide channel through the first connecting holes to dissipate heat from the motor, ensuring the motor's heat dissipation effect. In addition, the setting of multiple first connecting holes can also greatly reduce noise generation and improve the user experience.

[0018] As a preferred technical solution, the upper port of the first raised portion and the lower opening of the air guide channel are sealed by a sealing gasket.

[0019] As a preferred technical solution, the soymilk maker 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 the air outlet.

[0020] 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 expelled from the soymilk maker, so as to avoid the hot air generated affecting the components inside the outer casing.

[0021] As a preferred technical solution, the base is provided with a water guide hole near the air outlet, the volute is provided with a water collection cavity, and the bottom of the water collection cavity is provided with a drain hole communicating with the water guide hole.

[0022] By setting water guide holes on the base and drain holes communicating with the water collection chamber of the volute, liquid can be discharged through the water guide holes. Furthermore, placing the water guide holes near the air outlet further improves the compactness of the entire structure.

[0023] As a preferred technical solution, the inner side of the base is provided with an upwardly raised second bulge, and the second bulge is provided with a plurality of arrayed second connecting holes, which together form the air outlet.

[0024] By setting a second connecting hole on the second raised part to form an air outlet, water stains or dust can be prevented from entering the base through the air outlet. Moreover, when the soy milk maker is placed on the countertop, there is a certain space between the air outlet and the countertop, which can ensure that air can be smoothly discharged from the air outlet.

[0025] As a preferred technical solution, the power board and the air guide channel are disposed on the opposite side walls of the motor cover.

[0026] And / or, the motor is installed inside the motor cover, the lower end of the motor cover is fixed to the base by screws, and the upper end of the motor cover is fixed to the bottom of the inner cup by screws. Attached Figure Description

[0041] 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.

[0042] 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.

[0043] Considering that existing blenders and soymilk makers with independent heat dissipation structures for the motor have relatively bulky overall structures, making it impossible to install the inner cup and motor together, and requiring heat insulation and heat dissipation for the motor while achieving a compact overall structure, this application provides a soymilk maker that, while providing heat insulation and heat dissipation for the motor, results in a more compact internal structure and a smaller, more aesthetically pleasing overall design. It is understood that the structure of this embodiment is applicable not only to soymilk makers but also to other liquid heaters such as blenders and electric kettles; this embodiment only uses a soymilk maker as an example to illustrate its structure.

[0044] like Figure 1 This is a schematic diagram illustrating the separation of the soymilk maker cup lid 9 from the outer shell 2 according to an embodiment of this application. Figure 2 This is a cross-sectional view of the soymilk maker (hidden cup lid 9) described in the embodiment of this application. Figure 3 This is an exploded view of the soymilk maker described in the embodiments of this application. Figure 4 This is a schematic diagram of the structure of the soymilk maker with an air outlet 12 as described in the embodiment of this application. Figures 1-4 As shown, the soymilk maker includes a base 1, an outer shell 2, an inner cup 3, a partition plate 4, a motor cover 5, a motor 6, a power board 7, a volute 8, and a lid 9. The outer shell 2 is mounted on the base 1. The inner cup 3, partition plate 4, motor cover 5, motor 6, power board 7, and volute 8 are all housed within the outer shell 2. A handle 21 is mounted on the outer periphery of the outer shell 2, and a switch 211 is installed inside the handle 21. The lid 9 contains a lid-closing trigger rod and an anti-overflow electrode. The lid 9 is fastened to the top opening of the outer shell 2. When the lid 9 is rotated to a preset position, the lid-closing trigger rod on the lid 9 is electrically connected to the switch 211 to detect lid closure. The soymilk maker can only be started after the lid is fully closed. It is understood that the switch 211 inside the handle 21 can also be installed on other components such as the outer shell 2, as long as it enables lid closure detection. The aforementioned anti-overflow electrode is also electrically connected to switch 211. When the liquid in the inner cup 3 exceeds the preset liquid level and contacts the anti-overflow electrode, it generates an anti-overflow signal to adjust the operating strategy of the soymilk maker and achieve better processing of the ingredients.

[0045] In the embodiments of this application, such as Figure 3 As shown, 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 processing requirements. The heating tube 31, the isolation plate 4, and the motor cover 5 are arranged sequentially from top to bottom. The isolation plate 4 can isolate the heating tube 31 from the motor cover 5 to prevent the heat from the heating tube 31 from being transferred to the motor cover 5 and causing heat damage to the motor 6 and other electronic components inside the motor cover 5.

[0046] A cavity is formed between the aforementioned partition plate 4 and the motor cover 5, which can accommodate the motor 6. After the motor shaft of the motor 6 passes through the partition plate 4, it seals and extends into the inner cup 3 and is connected to the crushing blade 32 inside the inner cup 3, so as to drive the crushing blade 32 to rotate and crush the food.

[0047] Optionally, the lower end of the motor cover 5 is fixed to the base 1 with screws, and the upper end of the motor cover 5 is fixed to the bottom of the inner cup 3 with screws.

[0048] In this embodiment, the power board 7 is installed on the outside of the motor cover 5, so that the inner cup 3, the isolation plate 4, the motor cover 5, the motor 6, and the power board 7 form a grinding assembly. That is, by installing the power board 7 on the outside of the motor cover 5, the inner cup 3, the isolation plate 4, the motor cover 5, the motor 6, and the power board 7 form an integral grinding assembly. On the one hand, compared to a split-type blender structure, this application forms an integral grinding assembly within the outer casing 2, making the overall structure of the soymilk maker more compact, requiring less installation space inside the outer casing 2, and making the soymilk maker more compact. On the other hand, the integral grinding assembly not only makes the soymilk maker more compact but also reduces the vibration generated during the operation of the motor 6. Furthermore, forming an integral grinding assembly also facilitates assembly and effectively improves assembly efficiency.

[0049] Furthermore, compared to the structure where the power board 7 is located inside the base 1, this application mounts the power board 7 on the outside of the motor cover 5, which can also prevent water dripping from damaging the power board 7.

[0050] Preferably, the power board 7 and the air duct 51 are disposed on opposite side walls of the motor cover 5. This relatively symmetrical arrangement of the structure is conducive to making full use of the internal space of the outer casing 2.

[0051] In this embodiment, as Figure 2 and Figure 3 As shown, the side wall of the motor cover 5 is provided with an air guide channel 51 located on one side of the receiving cavity. This air guide channel 51 is independent of the receiving cavity (optionally, it can be as follows). Figure 3As shown, the air guide channel 51 and the receiving cavity are arranged in a left-right distribution. One side of the above-mentioned isolation plate 4 extends to the upper opening 511 of the air guide channel 51 and surrounds the motor cover 5 to form a connecting channel 10. The connecting channel 10 connects the air guide channel 51 and the receiving cavity to realize the flow of air in the air guide channel 51 to the receiving cavity.

[0052] The lower opening 512 of the aforementioned air guide channel 51 is connected to an air inlet 11. For example, an air inlet 11 can be provided on the base 1, and outside air can enter the air guide channel 51 through the air inlet 11, and then enter the receiving cavity through the air guide channel 51 to dissipate heat from the motor 6 in the receiving cavity.

[0053] 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 6 can flow out of the base 1. By setting an air flow path of air inlet 11-air guide channel 51-connecting channel 10-receiving cavity-air outlet 12, this embodiment can achieve independent cooling of the motor 6. Compared with the prior art, where air needs to circulate inside the outer casing 2 for a period of time before cooling the motor 6, the cooling efficiency of this embodiment is higher. Moreover, through the above-mentioned air flow path, the outside air directly cools the motor 6 without absorbing heat from other heat sources, resulting in a better cooling effect on the motor 6.

[0054] It should be understood that the air circulation path described above in this embodiment is used to dissipate heat from the motor 6. In addition, the soymilk maker may also have a heat dissipation structure for heat-generating components such as the power board 7. This heat dissipation structure may share the same air inlet 11 and air outlet 12, or it may have separate air inlet and air outlet channels. This embodiment will not elaborate further.

[0055] Figure 5 Examples of this application Figure 3 An enlarged diagram of point A, as shown below. Figure 5 As shown, the air guide channel 51 in this embodiment includes an upper opening 511, a lower opening 512, and a contraction section 513 located between the upper opening 511 and the lower opening 512. The contraction section 513 is constricted relative to the lower opening 512. By setting the contraction section 513, the cross-section of the air guide channel 51 exhibits a distribution pattern of first large and then small from bottom to top. This increases the air velocity flowing through the contraction section 513, thereby increasing the air velocity flowing towards the motor 6 through the Laval principle and enhancing the heat dissipation effect on the motor 6. Preferably, the opening area of ​​the lower opening 512 is larger than the opening area of ​​the upper opening 511, and the contraction section 513 is located in the middle of the air guide channel 51. By making the opening area of ​​the lower opening 512 larger than the opening area of ​​the upper opening 511, the air intake area can be increased, thereby increasing the air intake volume. At the same time, in conjunction with the contraction section 513, the air velocity and air volume delivered to the motor 6 can be further increased, improving the heat dissipation effect.

[0056] like Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the motor cover 5 according to an embodiment of this application. The motor cover 5 includes a body 52, which has a rectangular cavity structure. Inside the body 52, there are chambers with openings at both the upper and lower ends. The upper end of each chamber is connected to a partition plate 4, forming the aforementioned communication channel 10 between the chamber and the partition plate 4. The bottom of the chamber is fixedly connected to a base 1, and the opening at the lower end of the chamber communicates with an air outlet 12 on the base 1. Furthermore, the aforementioned receiving cavity is formed between the chamber and the partition plate 4.

[0057] The aforementioned air guide channel 51 is located on one side of the cavity. The air guide channel 51 and the main body 52 can be integrally formed by injection molding. This ensures the airtightness of the air guide channel 51 and facilitates the processing of the motor cover 5.

[0058] You can continue to refer to this. Figure 6 In this embodiment, the top of the inner wall of the main body 52 extends inward in a stepped structure 521 along the circumferential direction, and the edge of the partition plate 4 extends downward in a ring-shaped portion 41 ( Figure 3 As shown, the annular portion 41 is supported on the stepped structure 521. This structure allows the isolation plate 4 to be supported on the top of the motor cover 5, and also facilitates the installation and positioning of the isolation plate 4 and the motor cover 5.

[0059] Considering that the existing air inlet 11 located at the bottom of the base 1 has problems such as being too close to the table surface, affecting air intake, and allowing water stains or dust to easily enter, this application embodiment has further improved the structure of the air inlet 11. For example... Figures 7-9 As shown, where Figure 7 Examples of this application Figure 3 Enlarged diagram of point B, Figure 8 As described in the embodiments of this application Figure 2 Enlarged diagram at point C, Figure 9 This is a schematic diagram of the assembly structure of the volute 8 and the base 1 in an embodiment of this application. Figure 10 This is a schematic diagram of the structure of the base 1 described in this embodiment. In this embodiment, a first raised portion 13 is provided on the inner side of the base 1. An air inlet channel 131 is provided on the inner side of the first raised portion 13. The lower port of the air inlet channel 131 extends from the bottom wall of the base 1 to the side wall of the base 1 to form an air inlet 11. The upper port of the air inlet channel 131 is connected to the lower opening 512 of the air guide channel 51.

[0060] The aforementioned structure ensures that the air inlet channel 131 has a certain height, effectively preventing water stains or dust from entering the air guide channel 51 and the receiving cavity along with outside air, thus avoiding damage to the motor 6. Furthermore, the air inlet 11 extends from the bottom wall of the base 1 to its side wall, ensuring that it is not completely obstructed when the soymilk maker is placed on a countertop, thus guaranteeing unobstructed airflow. Moreover, the air inlet 11 is positioned such that even when the soymilk maker is placed in a corner, a gap exists between it and the corner, preventing any impact on airflow. Preferably, the air inlet 11 is located entirely within the transition area formed between the bottom wall and side wall of the base 1; this transition area can be an arc-shaped structure for better airflow.

[0061] Preferably, such as Figure 8 As shown, the upper port of the first raised portion 13 is inserted into the lower opening 512 of the air guide channel 51. This insertion structure facilitates the assembly and positioning of the air guide channel 51 of the motor cover 5 and the first raised portion 13, and also facilitates the sealing treatment between the first raised portion 13 and the air guide channel 51. For example, a sealing gasket 20 can be provided between the upper port of the first raised portion 13 and the lower opening 512 of the air guide channel 51 to achieve a sealed connection between the air guide channel 51 and the air inlet channel 131. For example, a sealing step 132 can be provided on the top of the first raised portion 13, and the sealing gasket 20 can be provided between the end face of the lower opening 512 of the air guide channel 51 and the sealing step 132, and the sealing gasket 20 has a through hole for the upper port of the first raised portion 13 to pass through.

[0062] like Figure 9 and Figure 10 As shown, the upper port of the first raised portion 13 is an array of multiple first connecting holes 133. By setting multiple first connecting holes 133, airflow can smoothly enter the air guide channel 51 through the first connecting holes 133 to dissipate heat from the motor 6, ensuring the heat dissipation effect of the motor 6. In addition, the setting of multiple first connecting holes 133 can also greatly reduce noise generation and improve the user experience. Furthermore, the small diameter of the first connecting holes 133 can also prevent large particles of dirt from entering the air guide channel 51, affecting heat dissipation and causing damage to the motor 6.

[0063] Optionally, such as Figure 9 and Figure 10As shown, in this embodiment, a second raised portion 14 is provided on the inner side of the base 1. The second raised portion 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 raised portion 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 soymilk maker 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.

[0064] In this embodiment, reference Figure 3 , Figure 8 and Figure 9 The aforementioned soymilk maker also includes a volute 8, which is disposed between the motor cover 5 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 8 can be accommodated within this cavity structure. The volute 8 and the base 1 together form a top-opening air-gathering cavity 30, which communicates with the receiving cavity through the top opening. The air-gathering cavity 30 also includes a spiral-shaped air outlet channel, which connects to the air outlet 12. Air entering the receiving cavity via the air guide channel 51 and the connecting channel 10 dissipates heat from the motor 6, then enters the air outlet channel and is finally discharged through the air outlet 12.

[0065] Optionally, such as Figure 9 and Figure 10 As shown, a support structure 15 is provided on the base 1, the bottom of the volute 8 is supported on the support structure 15, and a spiral structure is formed between one end of the side wall of the volute 8 and the other end. The two ends of the support structure 15 of the base 1 are also spiral structures. The air outlet channel is formed between the side wall of the volute 8 and the support structure 15 of the base 1.

[0066] Preferably, a fan 40 is provided inside the aforementioned air-gathering cavity 30. The fan 40 can quickly expel the air cooled by the motor 6, thus preventing the generated hot air from affecting the components inside the housing 2. It should be noted that the fan 40 is driven to rotate by the motor 6; that is, both ends of the motor 6 are provided with output shafts, and the lower output shaft of the motor 6 is connected to the fan 40. The fan 40 can also be controlled independently, i.e., driven to rotate independently by a drive component.

[0067] In this embodiment, as Figure 9As shown, a water-gathering cavity 81 is provided on the volute 8, located at the top of the volute 8 and directly opposite the air outlet 12. A drain hole 82 is provided at the bottom of the water-gathering cavity 81, and a water guide hole 16 is provided on the base 1 near the air outlet 12, communicating with the drain hole 82. This structure allows liquid to be discharged through the water guide hole 16, thereby preventing liquid in the soymilk maker from affecting components such as the power board 7. Furthermore, placing the water guide hole 16 near the air outlet 12 further improves the compactness of the entire structure.

[0068] In the above-described soymilk maker of this application embodiment, the inner cup 3 is installed together with the motor 6, and the heating element is isolated from the motor cover 5 by the isolation plate 4, which can achieve heat insulation for the motor 6. By setting the air guide channel 51 connecting the receiving cavity, heat dissipation of the motor 6 can be achieved. On this basis, the inner cup 3, isolation plate 4, motor cover 5, motor 6, and power board 7 form an integrated crushing assembly, making the overall structure of the soymilk maker more compact and smaller.
