Description

Technical Field

[0001] The present application relates to the field of cooking machines, and particularly to a heat dissipation structure for a cooking machine. Background Art

[0002] With its powerful motor drive and versatile accessory combination, a cooking machine greatly improves cooking efficiency and creative space. It can easily complete various kitchen tasks such as dough kneading, egg beating, stirring, and meat mincing. It not only saves manpower and time but also helps to improve the evenness and fineness of food material processing, making it an indispensable assistant in modern kitchens.

[0003] Among them, Chinese invention patent, application number: CN117547174A, discloses a driving device for a cooking machine and a cooking machine. The driving device of the cooking machine includes a head frame; a motor disposed on the head frame; a sun shaft for driving the planet gears to rotate; an output shaft, and a stirring mechanism is detachably connected to the lower end of the output shaft and / or the sun shaft. The output shaft rotatably passes through the planet carrier, and the output shaft is fixedly connected to the planet gears; a transmission mechanism is connected between the motor and the planetary gear train for driving the sun shaft to rotate; the number of the planet gears is at least one. It realizes the function of stirring food materials in all directions both centrally and circumferentially, with a fast stirring speed and no dead angle in stirring; the stirring mechanism is detachably connected, which is convenient for quickly replacing different types of stirring mechanisms to be suitable for the processing of different food materials, increasing the diversity of food materials that can be processed by this technical solution and being conducive to popularization and application.

[0004] It drives the sun shaft to rotate by driving the transmission mechanism through the motor. Since the transmission mechanism is arranged in the gearbox, however, when the output shaft of the motor drives the transmission mechanism to rotate in the gearbox, there is mechanical friction between the mechanical components, thus generating heat. As the working time of the driving transmission mechanism and the motor increases, the heat of the motor and the driving transmission mechanism cannot be dissipated in time, accelerating the speed of irreversible mechanical loss between the components, and there is room for improvement. Utility Model Content

[0005] In order to improve the heat dissipation performance of the cooking machine, the present application provides a heat dissipation structure for a cooking machine.

[0006] The heat dissipation structure for a cooking machine provided by the present application adopts the following technical solution:

[0007] A heat dissipation structure for a cooking machine includes a mounting part, a gearbox, and a motor. The gearbox and the motor are disposed on the mounting part. The output shaft of the motor is coaxially fixed to the input shaft of the gearbox. It further includes a heat dissipation component. The heat dissipation component includes a heat dissipation fan and a heat dissipation pipeline. Two ends of the heat dissipation pipeline are respectively communicated with the gearbox and the motor. The heat dissipation fan is disposed on the mounting part, and the air inlet of the heat dissipation fan is communicated with the motor.

[0008] By adopting the above technical solution, since the output shaft of the motor is coaxially fixed to the input shaft of the gearbox, when the output shaft of the motor rotates, the output shaft of the motor drives the input shaft of the gearbox to rotate synchronously, so that the output shaft of the gearbox rotates along the gearbox, realizing power output. Since both ends of the heat dissipation pipeline are connected to the gearbox, and the air inlet of the heat dissipation fan is connected to the motor, when the heat dissipation fan starts to work, using the suction force provided by the heat dissipation fan, the heat in the gearbox is forced to enter the motor through the heat dissipation pipeline. Subsequently, the heat inside the motor enters the heat dissipation fan again through the air inlet of the heat dissipation fan and is blown out from the air outlet of the heat dissipation fan, thus achieving the purpose of simultaneously dissipating heat inside the gearbox and the motor, and only a single heat dissipation fan is required, which plays a positive guiding role in improving the heat dissipation performance of the cooking machine.

[0009] Preferably, a fixing seat is arranged on the mounting part, the fixing seat is used to fix the motor, a communication hole is opened on the fixing seat, the communication hole is used to communicate with the inside of the motor, and the heat dissipation fan is arranged on the fixing seat.

[0010] By adopting the above technical solution, the motor is fixed by the mounting part, so that the motor is stably mounted on the mounting part, reducing the shaking of the motor during operation. At the same time, a communication hole is opened on the fixing seat, and the heat dissipation fan is arranged on the fixing seat, so that the heat inside the motor can quickly enter the heat dissipation fan along the communication hole, which plays a positive guiding role in improving the heat dissipation performance of the heat dissipation fan.

[0011] Preferably, fixing guide posts are arranged on the fixing seat, mounting holes are opened on the heat dissipation fan, and the mounting holes are in plug-in fit with the fixing guide posts.

[0012] By adopting the above technical solution, through the cooperation of the fixing guide posts and the mounting holes, it is convenient to quickly install the heat dissipation fan on the fixing seat, reducing the adjustment time when the heat dissipation fan is installed on the fixing seat, and at the same time, it is also beneficial to reduce the position deviation when the heat dissipation fan is installed on the fixing seat, so as to keep the air inlet area of the air inlet of the heat dissipation fan.

[0013] Preferably, a first plug post is arranged on the fixing seat, the first plug post communicates with the inside of the motor, a second plug post is arranged on the gearbox, the second plug post communicates with the inside of the gearbox, and both ends of the heat dissipation pipeline are in plug-in fit with the first plug post and the second plug post respectively.

[0014] By adopting the above technical solution, during the assembly process, only the two ends of the heat dissipation pipeline need to be respectively in plug-in fit with the first plug post and the second plug post, which is convenient for disassembling and assembling the heat dissipation pipeline.

[0015] Preferably, fixing pieces are arranged on the heat dissipation pipeline.

[0016] By adopting the above technical solution, fixing the heat dissipation pipeline through the fixing piece is beneficial to improving the stability of the cooperation between both ends of the heat dissipation pipeline and the first plug post and the second plug post, and reducing the probability of loosening in the cooperation between the heat dissipation pipeline and the first plug post and / or the second plug post.

[0017] Preferably, a plurality of air circulation holes are formed in the installation part, and the air outlet of the heat dissipation fan faces the air circulation holes.

[0018] By adopting the above technical solution, when the heat is blown out along the air outlet of the heat dissipation fan, the power provided by the heat dissipation fan is used to blow the heat towards the air circulation holes, so that the heat quickly dissipates along the installation part, reducing the heat accumulated in the installation part.

[0019] Preferably, a first stop block and a second stop block are arranged inside the second plug post, and the first stop block and the second stop block are arranged in a staggered manner along the height direction of the inner wall of the second plug post.

[0020] By adopting the above technical solution, since the first stop block and the second stop block are arranged in a staggered manner along the height direction of the inner wall of the second plug post, the air flow flowing from the inside of the gearbox to the second plug post moves in a curve shape, reducing the probability of the lubricating oil inside the gearbox flowing along the second plug post to the heat dissipation pipeline due to the strong suction provided by the heat dissipation fan.

[0021] Preferably, a sealing and shock-absorbing pad is arranged between the fixing seat and the abutting surface of the motor.

[0022] By adopting the above technical solution, the sealing and shock-absorbing pad is beneficial to improving the tightness between the fixing seat and the abutting surface of the motor, reducing the probability of the suction of the heat dissipation fan being reduced due to the gap between the fixing seat and the abutting surface of the motor. At the same time, through the buffering effect of the sealing and shock-absorbing pad, it is beneficial to reduce the noise generated by the shaking during the operation of the heat dissipation fan and / or the motor.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the heat dissipation fan starts to work, using the suction provided by the heat dissipation fan, the heat inside the gearbox is forced to enter the motor along the heat dissipation pipeline. Subsequently, the heat inside the motor enters the heat dissipation fan again from the air inlet of the heat dissipation fan and is blown out from the air outlet of the heat dissipation fan, so as to achieve the purpose of simultaneously dissipating the heat inside the gearbox and the motor, which plays a positive guiding role in improving the heat dissipation performance of the cooking machine;

[0025] 2. By means of the cooperation between the fixed guide posts and the mounting holes, it is convenient to quickly mount the cooling fan on the fixed seat, which helps to reduce the position deviation when the cooling fan is mounted on the fixed seat, so as to maintain the air intake area of the air inlet of the cooling fan.

[0026] 3. Since the first stop block and the second stop block are arranged in a staggered manner along the height direction of the inner wall of the second insertion post, the air flow flowing from the inside of the gearbox to the second insertion post moves in a curved shape, reducing the probability of the lubricating oil inside the gearbox flowing along the second insertion post to the heat dissipation pipeline due to the strong suction provided by the cooling fan.

Detailed Embodiment

[0032] The following Figures 1-4 further describes the present application in detail.

[0033] The embodiment of the present application discloses a heat dissipation structure for a chef machine. Refer to Figure 1 and Figure 2, A heat dissipation structure for a cooking machine includes an installation part 1, a gearbox 2, a motor 3, and a heat dissipation component 4. The gearbox 2 and the motor 3 are arranged on the installation part 1. The output shaft of the motor 3 is coaxially fixed to the input shaft of the gearbox 2. The heat dissipation component 4 includes a heat dissipation fan 41 and a heat dissipation pipeline 42. The two ends of the heat dissipation pipeline 42 are respectively connected to the gearbox 2 and the motor 3. The heat dissipation fan 41 is arranged on the installation part 1, and the air inlet of the heat dissipation fan 41 is connected to the motor 3.

[0034] First of all, it should be noted that the gearbox 2 and the motor 3 are driving components of an existing cooking machine, which are prior art, and their specific compositions and working principles will not be elaborated here.

[0035] Therefore, since the output shaft of the motor 3 is coaxially fixed to the input shaft of the gearbox 2, when the output shaft of the motor 3 rotates, the output shaft of the motor 3 drives the input shaft of the gearbox 2 to rotate synchronously, so that the output shaft of the gearbox 2 rotates along the gearbox 2, realizing power output.

[0036] At the same time, since the two ends of the heat dissipation pipeline 42 are connected to the gearbox 2, and the air inlet of the heat dissipation fan 41 is connected to the motor 3, when the heat dissipation fan 41 starts to work, using the suction force provided by the heat dissipation fan 41, the heat in the gearbox 2 is forced to enter the interior of the motor 3 along the heat dissipation pipeline 42. Subsequently, the heat inside the motor 3 enters the heat dissipation fan 41 again from the air inlet of the heat dissipation fan 41 and is blown out from the air outlet of the heat dissipation fan 41, thus achieving the purpose of simultaneously dissipating heat inside the gearbox 2 and the motor 3, and only a single heat dissipation fan 41 is required, which plays a positive guiding role in improving the heat dissipation performance of the cooking machine.

[0037] Refer to Figure 2 and Figure 3 , A fixing seat 5 is arranged on the installation part 1. The fixing seat 5 is used to fix the motor 3. A communication hole 51 is opened on the fixing seat 5, and the communication hole 51 is used to communicate with the interior of the motor 3. The heat dissipation fan 41 is arranged on the fixing seat 5.

[0038] Specifically, an installation seat 11 is arranged on the installation part 1. The fixing seat 5 is fixed to the installation seat 11 by bolts. When the fixing seat 5 is installed on the installation seat 11, a fixing area adapted to the external contour of the motor 3 is formed between the fixing seat 5 and the installation seat 11. After the motor 3 is installed in the fixing area, the motor 3 can be locked by using the cooperation of the fixing seat 5 and the installation seat 11 through fastening bolts, so that the motor 3 is stably installed on the installation part 1, improving the stability of the motor 3 when installed on the installation part 1.

[0039] Furthermore, the communication holes 51 are located at one end of the fixed seat 5 away from the abutting surface with the mounting seat 11. At the same time, the driving motor 3 is provided with circulation holes, and the communication holes 51 communicate with the circulation holes. When the cooling fan 41 is installed on the fixed seat 5, the air inlet of the cooling fan 41 faces the communication holes 51. When the cooling fan 41 starts to work, the air inlet of the cooling fan 41 is in a negative pressure state, so as to force the heat inside the motor 3 to enter the cooling fan 41 along the communication holes 51 through the air inlet of the cooling fan 41 and be discharged from the air outlet of the cooling fan 41.

[0040] Correspondingly, a sealing and shock-absorbing pad 8 is arranged between the abutting surface of the fixed seat 5 and the motor 3. The sealing and shock-absorbing pad 8 can be made of an elastic material, such as rubber. The sealing and shock-absorbing pad 8 is beneficial to improving the tightness of the abutting surface between the fixed seat 5 and the motor 3 and reducing the probability of the suction force of the cooling fan 41 being reduced due to the gap between the abutting surfaces of the fixed seat 5 and the motor 3. At the same time, through the buffering effect of the sealing and shock-absorbing pad 8, it is beneficial to reduce the noise generated by the shaking during the operation of the cooling fan 41 and / or the motor 3.

[0041] On the other hand, the fixed seat 5 is provided with fixed guide posts 52, and the cooling fan 41 is provided with mounting holes, and the mounting holes are in plug-in fit with the fixed guide posts 52. The cooling fan 41 can be fixed to the fixed seat 5 by bolts. Among them, the fixed guide posts 52 and the fixed seat 5 are integrally formed, reducing the probability of the fixed guide posts 52 breaking along the fixed seat 5. Therefore, through the cooperation of the fixed guide posts 52 and the mounting holes, it is convenient to quickly install the cooling fan 41 on the fixed seat 5, reduce the adjustment time when the cooling fan 41 is installed on the fixed seat 5, and at the same time is also beneficial to reducing the position deviation when the cooling fan 41 is installed on the fixed seat 5, so as to maintain the air inlet area of the air inlet of the cooling fan 41.

[0042] At the same time, the heat dissipation pipeline 42 is provided with a fixing member 6, such as a clamp or a cable tie. After the two ends of the heat dissipation pipeline 42 are respectively in plug-in fit with the first plug post 53 and the second plug post 54, the heat dissipation pipeline 42 is fixed by the fixing member 6, improving the stability of the cooperation between the heat dissipation pipeline 42 and the first plug post 53 and the second plug post 54, and reducing the probability of the cooperation between the heat dissipation pipeline 42 and the first plug post 53 and / or the second plug post 54 becoming loose.

[0043] In addition, the installation part 1 is provided with a plurality of air circulation holes 7, and the air outlet of the cooling fan 41 faces the air circulation holes 7. The plurality of air circulation holes 7 penetrate through the installation part 1 in the thickness direction. When the heat is blown out from the air outlet of the cooling fan 41, the power provided by the cooling fan 41 is used to blow the heat towards the air circulation holes 7, so that the heat can be quickly dissipated along the installation part 1, reducing the heat accumulated in the installation part 1.

[0044] Reference Figure 3 and Figure 4 Inside the second plug post 54, a first stop block 541 and a second stop block 542 are provided. The first stop block 541 and the second stop block 542 are arranged in a staggered manner along the height direction of the inner wall of the second plug post 54.

[0045] Specifically, the cross-sectional shapes of the first stop block 541 and the second stop block 542 are semicircular. The first stop block 541 and the second stop block 542 are centrally symmetric about the midpoint along the length direction of the second plug post 54. The first stop block 541 and the second stop block 542 are integrally formed with the second plug post 54. That is, when the heat inside the gearbox 2 is affected by the suction force of the cooling fan 41, it will move along the second plug post 54 towards the cooling pipeline 42.

[0046] When the heat reaches the first stop block 541, due to the blocking effect of the first stop block 541, the flow direction of the gas flowing inside the second plug post 54 is forced to change. When the gas reaches the second stop block 542, the second stop block 542 changes the gas flow direction again, and finally flows into the cooling pipeline 42 along the second plug post 54.

[0047] Thus, because the first stop block 541 and the second stop block 542 are arranged in a staggered manner along the height direction of the inner wall of the second plug post 54, through the blocking effects of the first stop block 541 and the second stop block 542, the airflow flowing from inside the gearbox 2 to the second plug post 54 moves in a curved shape, reducing the probability of the lubricating oil inside the gearbox 2 flowing along the second plug post 54 into the cooling pipeline 42 due to the relatively strong suction force provided by the cooling fan 41.

[0048] The implementation principle of a heat dissipation structure for a chef machine in an embodiment of the present application is as follows: The cooling pipeline 42 is used to connect the gearbox 2 and the motor 3. At the same time, the air inlet of the cooling fan 41 is connected to the inside of the motor 3. When the cooling fan 41 starts to work, a negative pressure is generated at the air inlet of the cooling fan 41, thereby driving the heat inside the gearbox 2 to enter the inside of the motor 3 through the cooling pipeline 42. Subsequently, the heat located inside the motor 3 is affected by the suction force of the cooling fan 41, driving the heat to move towards the air inlet of the cooling fan 41 along the inside of the motor 3, and finally dissipating through the air outlet of the cooling fan 41, which plays a positive guiding role in reducing the temperatures of the gearbox 2 and the motor 3 during operation.

[0049] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
