Description

Technical Field

[0001] This utility model belongs to the field of soymilk maker technology, and more specifically, it relates to a soymilk maker air duct. Background Technology

[0002] Soy milk makers are common kitchen appliances, widely used in homes and various catering establishments. They use a motor to drive blades to rotate at high speed, thoroughly mixing and grinding soybeans with water, and can also be heated. During use, the continuous operation of the motor driving the blades to grind the ingredients and the prolonged operation of the heating elements generate heat, which can easily accumulate over time. However, traditional soy milk makers focus on the function of grinding soybeans, neglecting the large amount of heat generated by the motor and control board during operation. The inability to effectively dissipate this heat can easily lead to overheating of the motor and control board, which not only accelerates the aging of electronic components within the motor and control board but may also cause malfunctions due to prolonged operation in high-temperature environments, thus shortening the lifespan of the soy milk maker. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a soymilk maker air duct, which solves the technical problem that traditional soymilk makers cannot effectively dissipate the heat generated during operation, easily leading to heat accumulation in internal components, causing component aging and soymilk maker malfunctions.

[0004] The purpose and function of this utility model's air duct for a soymilk maker are achieved through the following specific technical means:

[0005] A soymilk maker air duct includes a pot body, a bottom cover, and an inner liner. The bottom cover is located at the bottom of the pot body, and the inner liner is installed inside the pot body. The three are interconnected to form an installation cavity. A gap is formed between a bracket and the bottom cover. Air inlets are provided on both sides of the bottom cover, and multiple sets of air outlets are provided at the bottom of the bottom cover. A bracket is installed in the installation cavity, and gaps are formed between the bracket and the bottom cover and the inner liner. A heat dissipation air duct is formed through the gaps with the air inlets and air outlets. A motor and an electronic control board are installed on the bracket, both located in the heat dissipation air duct. One end of the motor passes through the inner liner and is equipped with a blade, and the other end is equipped with a fan blade.

[0006] According to a preferred embodiment, the bracket is located between the inner liner and the bottom cover. The bracket is provided with a first mounting area and a second mounting area. The first mounting area is located above the second mounting area. The motor is installed in the first mounting area, and the electronic control board is installed in the second mounting area. A through hole is provided in the bracket, and the first mounting area communicates with the second mounting area through the through hole.

[0007] According to a preferred embodiment, the bracket is provided with a bone position located at the edge of the through hole and extending into the second mounting area.

[0008] According to a preferred embodiment, the rib is cone-shaped and hollow, with the bottom diameter of the rib being smaller than the top diameter, and the rib's inclination is along the airflow direction; the fan blade is disposed on the bottom shaft end of the motor and located within the rib, with the fan blade's diameter being smaller than the minimum diameter of the rib, and the fan blade blowing air upwards.

[0009] According to a preferred embodiment, a mounting bracket is provided inside the mounting cavity, the mounting bracket is located between the bracket and the inner liner, a bearing is provided on the mounting bracket, and the top bearing of the motor passes through the bearing.

[0010] According to a preferred embodiment, partitions are provided on both sides of the bracket, and the bracket forms a ventilation cavity by contacting the bottom cover through the partitions. The ventilation cavity is connected to the mounting cavity through the heat dissipation duct, and the ventilation cavity is connected to the outside through the air inlet.

[0011] According to a preferred embodiment, the air outlet protrudes into the mounting cavity, forming a stepped shape with the bottom cover.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This soymilk maker consists of a pot body, a bottom lid, and an inner liner. The air inlets on both sides of the bottom lid and multiple air outlets at the bottom, together with the gaps between the support frame, the bottom lid, and the inner liner, form a heat dissipation duct, placing the motor and control board within this duct. When the fan blades at the bottom of the motor rotate, air enters through the air inlets and flows within the duct, effectively dissipating heat from the motor and control board from all directions. This promptly removes the large amount of heat generated during operation, preventing heat buildup, significantly reducing the rate of component aging, minimizing the possibility of malfunctions due to overheating, effectively extending the lifespan of the soymilk maker, and ensuring stable and efficient operation.

[0014] 2. The first and second mounting areas on the bracket are used to mount the motor and the electronic control board, respectively, and the two are connected by a through hole. The ribs extending from the edge of the through hole into the second mounting area better guide airflow and enhance heat dissipation. The ribs are conical and hollow, inclined along the airflow direction, with the fan blades located inside the ribs and blowing upwards. This design allows the air blown by the fan blades to flow more concentratedly and orderly through the motor and electronic control board, further improving heat dissipation efficiency. In addition, the partitions on both sides of the bracket and the bottom cover form a ventilation cavity, increasing the airflow path. The air outlet protrudes into the mounting cavity, forming a stepped shape, which helps the air to escape more smoothly and avoids blockage. This comprehensively improves the heat dissipation performance of the entire air duct system, ensuring the long-term stable operation of the soymilk maker. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 6As shown, this utility model provides a soymilk maker air duct, including a pot body 11, a bottom cover 12, and an inner liner 13. The pot body 11 serves as the external frame of the entire soymilk maker, providing a mounting base for other components. The bottom cover 12 is located at the bottom of the pot body 11, serving to enclose the bottom space; it is connected to the pot body 11 using a common connection method. The inner liner 13 is installed inside the pot body 11. After the three are connected, they form a mounting cavity. This mounting cavity is used to accommodate the core operating components of the soymilk maker, providing them with a stable working environment. A bracket 31 is installed in the mounting cavity, with a certain gap between it and the bottom cover 12. Air inlets 21 are provided on both sides of the bottom cover 12, serving as channels for outside air to enter the soymilk maker. Simultaneously, multiple sets of air outlets 22 are also provided at the bottom of the bottom cover 12. The gaps between the bracket 31, the bottom cover 12, and the inner liner 13, in conjunction with the air inlets 21 and air outlets 22, form a heat dissipation air duct. Within this cooling duct, a motor 32 and an electronic control board 33 are mounted on the bracket 31. The motor 32 is the power source for the soymilk maker; one end passes through the inner pot 13, and a blade 41 is installed at the end for grinding ingredients. A fan 42 is installed at the other end of the motor 32. When the motor 32 operates, it not only drives the blade 41 to rotate, but the fan 42 also rotates. The airflow generated by the fan 42 is drawn in through the air inlet 21 and exhausted through the air outlet 22, thus cooling the motor 32 and the electronic control board 33 and ensuring the normal operation of the soymilk maker.

[0026] The support bracket 31 is located between the inner pot 13 and the bottom cover 12. It plays a supporting and layout role in the internal structure of the soymilk maker. The support bracket 31 has two specific areas: a first mounting area and a second mounting area. The first mounting area is located above the second mounting area, where the motor 32 is installed. It is stably positioned here and maintains a relatively stable state during operation. The control board 33 is installed in the second mounting area, each functioning within its corresponding area. Simultaneously, a through-hole is provided inside the support bracket 31, allowing the first and second mounting areas to communicate and providing a channel for air circulation, which helps with heat transfer and dissipation. A rib 34 is also provided inside the support bracket 31, located at the edge of the through-hole and extending towards the second mounting area.

[0027] The rib 34 is cone-shaped and hollow, with its bottom diameter smaller than its top diameter, and its tilt direction is consistent with the airflow direction. The fan blade 42 is mounted on the shaft end at the bottom of the motor 32 and is located inside the rib 34. The diameter of the fan blade 42 is smaller than the minimum diameter of the rib 34. When the motor 32 is running, the fan blade 42 blows air upwards, allowing the air blown by the fan blade 42 to better participate in the entire heat dissipation process under the guidance of the rib 34.

[0028] Inside the mounting cavity, there is also a mounting bracket 35, located between the bracket 31 and the inner liner 13. The mounting bracket 35 has a bearing mounted on it, and the bearing at the top of the motor 32 passes through this bearing. The mounting bracket 35 further stabilizes the motor 32, allowing it to maintain better stability during high-speed operation and reducing the impact of vibration and other factors on the overall operation of the soymilk maker. This ensures that all components of the soymilk maker work together normally, guaranteeing its normal use.

[0029] like Figure 1 , Figure 4 As shown, the bracket 31 has partitions 36 on both sides. When the bracket 31 contacts the bottom cover 12 through the partitions 36, a ventilation cavity is formed between them. This ventilation cavity is connected to the mounting cavity through a heat dissipation duct. When the soymilk maker is running, the motor 32 and the control board 33 in the mounting cavity generate heat. This heat enters the heat dissipation duct with the airflow, and the ventilation cavity becomes an important channel for airflow. At the same time, the ventilation cavity is also connected to the outside through the air inlet 21, allowing cold air from the outside to enter the ventilation cavity and participate in the heat dissipation cycle, continuously replenishing the cold air and enhancing the heat dissipation effect.

[0030] The air outlet 22 on the bottom cover 12 protrudes towards the interior of the mounting cavity, forming a stepped shape with the bottom cover 12. This structure makes it easier for the air outlet 22 to expel hot air. As the hot air generated by the operation of the soymilk maker flows from the heat dissipation duct to the air outlet 22, this stepped structure helps the hot air to be expelled more efficiently, reducing the blockage of air at the air outlet 22. This allows the hot air to be smoothly expelled from inside the soymilk maker to the outside, further optimizing the heat dissipation performance of the entire soymilk maker's air duct and ensuring the normal operation environment of the internal components of the soymilk maker.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using this soy milk maker, first put an appropriate amount of ingredients and water into the inner pot 13 and close the lid 11. Connect the power and start the soy milk maker. At this time, the motor 32 starts to work, and the blade 41 at one end of the motor 32 starts to rotate with the motor, crushing and processing the ingredients in the inner pot 13.

[0033] While the motor 32 is working, the fan blade 42 at its other end also rotates synchronously. The suction generated by the rotation of the fan blade 42 causes outside air to enter the soymilk maker from the air inlets 21 on both sides of the bottom cover 12. After the air enters, it flows along the heat dissipation air channel formed between the bracket 31, the bottom cover 12, and the inner liner 13. During this process, the flowing air will carry away the heat generated by the motor 32 and the electronic control board 33 when they are working.

[0034] Because the internal ribs 34 of the bracket 31 are conical and hollow, and their tilt direction is consistent with the airflow direction, the air blown out by the fan blades 42 flows more orderly through the motor 32 and the electronic control board 33 under the guidance of the ribs 34, thus enhancing the heat dissipation effect. At the same time, the ventilation cavity formed by the partitions 36 on both sides of the bracket 31 and the bottom cover 12 continuously replenishes the outside cold air through the air inlet 21, providing a continuous supply of cold air to the heat dissipation duct and strengthening the heat dissipation circulation.

[0035] The air, carrying the heat from the motor 32 and the control board 33, flows along the cooling duct to the air outlet 22 at the bottom of the base cover 12. Because the air outlet 22 protrudes into the mounting cavity, forming a stepped shape with the base cover 12, the hot air can be discharged from the soymilk maker more smoothly, completing the entire heat dissipation process and ensuring that the motor 32 and the control board 33 operate stably at a suitable temperature, allowing the soymilk maker to successfully complete the soymilk making task.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
