Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, and more specifically to a food processing machine. Background Technology

[0002] Existing food processing machines, such as blenders or soy milk makers, typically include a main unit and a grinding cup installed in the main unit. The grinding cup contains grinding blades, and the main unit contains a motor to drive the grinding blades to rotate and grind the ingredients. Since the motor generates heat, a cooling fan is usually installed at the rear of the motor. The rotation of the cooling fan causes airflow to pass through the motor and be exhausted from the exhaust duct of the main unit, thereby carrying away the heat from the motor and achieving the effect of motor cooling.

[0003] For example, Chinese Patent CN210961675U discloses a food processing machine with good heat dissipation, including a base with a built-in motor and a mixing cup on the base. The mixing cup includes a cup body, a cup lid, and a pulverizing blade driven by the motor. A cooling fan is provided at the bottom of the motor. The cooling fan is a centrifugal fan. The base includes a main body, a base at the bottom of the main body, and a control board inside the main body. The base has an air inlet, an air outlet, and an exhaust channel. The exhaust channel is volute-shaped, and the cooling fan is located in the center of the exhaust channel. The control board is located above the air inlet. When the cooling fan rotates, external air enters the base through the air inlet and is discharged through the air outlet after passing through the exhaust channel, effectively dissipating heat from the electrical components inside the base, resulting in ideal heat dissipation. However, with the cooling fan located in the center of the exhaust duct, the exhaust duct itself essentially defines a fan housing cavity coaxially with it. The cooling fan is essentially directly connected to the outside. Therefore, the noise generated during the rotation of the cooling fan will be directly transmitted into the exhaust duct and directly to the outside, resulting in significant noise. Moreover, the existing exhaust duct path is relatively short, and the air pressure generated by the fan blades is relatively high, resulting in a high-frequency whistling sound at the air outlet of the host unit, making the noise reduction effect unsatisfactory.

[0004] Some food processing machines now use baffles in the exhaust duct or at the air outlet to reduce noise, but this design affects the efficiency of airflow and has a certain impact on the heat dissipation of the motor.

[0005] In some cooking appliances, such as the Chinese patent with publication number CN215016378U, a cooking appliance is disclosed, including a fan assembly and a heating element disposed above the fan assembly. The fan assembly includes: a volute body, including a base plate and a surrounding plate disposed on the front side of the base plate; a fan disposed within the volute body; the surrounding plate has a spiral cross-section; and the fan and the volute body are eccentrically positioned. In this design, the fan blows air within the volute body, which guides the air to the heating element, and the heated air from the heating element is blown into the interior of the cooking appliance to heat the food. The spiral cross-section of the surrounding plate ensures uniform airflow, allowing air to enter the heating element evenly under the guidance of the fan and the surrounding plate. The eccentric positioning of the fan and the volute body narrows the air passage between the surrounding plate and the fan near the first end, compressing the air and increasing the air pressure, giving the air blown out of the fan assembly greater kinetic energy. This solves the problem of localized high temperatures in the heating element, but it does not solve the problem of excessive fan noise.

[0006] Therefore, in existing food processing machines, especially those with pulverizing functions, there is a problem of relatively high heat dissipation noise, even while ensuring good heat dissipation of the motor. Summary of the Invention

[0007] The purpose of this invention is to provide a food processing machine that solves the problem of excessive heat dissipation noise in existing food processing machines while ensuring good heat dissipation of the motor.

[0008] To achieve the above objectives, the present invention provides a food processing machine, including a machine body and a grinding cup disposed in the machine body. The grinding cup is equipped with a grinding device. The machine body includes a housing, a motor disposed in the housing, a cooling fan disposed at the bottom of the motor, and an exhaust assembly. The motor is used to drive the grinding device to rotate. The exhaust assembly is provided with a heat dissipation cavity and a heat dissipation channel. The cooling fan extends into the heat dissipation cavity. The heat dissipation channel is arranged side by side on the side of the heat dissipation cavity and communicates with the heat dissipation cavity. The heat dissipation channel extends in a spiral shape.

[0009] The food processing machine provided in this application features a cooling fan that rotates within the cooling cavity, generating suction that draws airflow from top to bottom through the motor into the cooling cavity. The airflow carries away heat from the motor, achieving a cooling effect. Cooling channels are arranged side-by-side on the sides of the cooling cavity and communicate with it, guiding airflow laterally from the cooling cavity into the channels and then discharging it to the outside. Therefore, the airflow direction changes from top to bottom to a laterally bent path under the action of the cooling fan blades before entering the cooling channels. During this process, the airflow path is tortuous, extending the airflow path and preventing direct noise transmission to the cooling channels, thus achieving primary noise reduction. Furthermore, the lateral entry of airflow from the cooling cavity into the cooling channels consumes a significant amount of wind pressure energy, reducing the frequency of the wind pressure discharged to the outside and preventing high-frequency whistling noise. The spiral extension of the cooling channels further extends the airflow path and achieves secondary noise reduction, further reducing the noise generated by the cooling fan and resulting in a good noise reduction effect. Furthermore, this application achieves secondary noise reduction through the arrangement of the heat dissipation cavity and heat dissipation channels. Compared to the traditional method of setting baffles within the channels for noise reduction, this avoids affecting airflow efficiency. Therefore, this application can achieve a balance between the overall heat dissipation effect and noise reduction effect of the exhaust assembly, reducing heat dissipation noise while ensuring good heat dissipation of the motor. On the other hand, the heat dissipation channels are arranged side by side on the side of the heat dissipation cavity. In addition to reducing noise, this also allows for the rational use of the internal space of the casing, and avoids increasing the height of the main unit, lowering the center of gravity of the main unit and ensuring stable operation.

[0010] Preferably, the exhaust assembly includes a transition structure that connects the heat dissipation cavity and the inlet of the heat dissipation channel.

[0011] Since the airflow needs to bend laterally when entering the heat dissipation channel from the heat dissipation cavity, a transition structure can be set to make the airflow smoother, thus ensuring good heat dissipation while maintaining noise reduction.

[0012] Preferably, the bottom wall of the heat dissipation cavity is lower than the inlet bottom wall of the heat dissipation channel, and the transition structure includes an inclined flow guide plate that connects the bottom wall of the heat dissipation cavity to the inlet bottom wall of the heat dissipation channel.

[0013] The bottom wall of the heat dissipation cavity is lower than the bottom wall of the heat dissipation channel inlet, which allows for the rational and effective use of the internal space of the casing. This ensures that the height of the heat dissipation cavity is sufficient to accommodate the cooling fan and increase the airflow, thereby improving the cooling effect of the motor. By setting a relatively high, inclined, and extended airflow guide plate at the inlet of the heat dissipation channel, the heat dissipation channel is ensured to have sufficient height. This maximizes the airflow within the limited space of the casing, extends the airflow path, and ensures smooth flow, thereby reducing noise.

[0014] Preferably, the inner height of the heat dissipation cavity is greater than the inlet height of the heat dissipation channel.

[0015] The height of the heat dissipation cavity is greater than the inlet height of the heat dissipation channel. Therefore, the airflow will encounter a reduction in the inlet cross-sectional area as it enters the heat dissipation channel from the heat dissipation cavity, which partially cancels out the airflow noise and further achieves a first-level noise reduction effect.

[0016] Preferably, the heat dissipation channel is divided into an upper air duct and a lower air duct. The upper air duct forms the entrance to the heat dissipation channel at its upstream end, and the lower air duct is connected to the downstream end of the upper air duct, so that the heat dissipation airflow is spiraled out from top to bottom.

[0017] The heat dissipation channel is divided into an upper air duct and a lower air duct, forming an upper spiral air duct. After the airflow spirals through the upper air duct, it enters the lower air duct and continues its spiral flow before being discharged to the outside. Therefore, the airflow undergoes two reversals while passing through the heat dissipation channel, resulting in a tortuous path and reduced noise. Furthermore, because the heat dissipation channel and heat dissipation cavity are arranged in parallel, this arrangement allows the heat dissipation channel to form a double layer within a limited space, reversing the airflow twice. This ensures noise reduction while making efficient use of the internal space of the casing, resulting in a compact structure and avoiding an increase in the height of the main unit, thus reducing the overall height of the food processing machine.

[0018] Preferably, the exhaust assembly includes a base and a volute encapsulated at the bottom of the housing. The base has a mounting cavity, and the volute is installed in the mounting cavity, which together with the cavity wall defines a heat dissipation channel. The top of the mounting cavity has a notch for the cooling fan to extend into, and the notch is laterally offset from the volute to form a heat dissipation cavity within the mounting cavity.

[0019] As the main supporting component of the food processing machine, the base needs to have a large structural strength. By setting an installation cavity in the base, the volute and the base form a heat dissipation channel with good noise reduction effect. On the other hand, the volute strengthens the structure of the base, prevents the base from deforming, and ensures the strength of the base.

[0020] Preferably, the volute includes a shell and a bottom cover that is fastened to the bottom of the shell, and the bottom surface of the bottom cover is provided with a groove.

[0021] The volute consists of a shell and a bottom cover, which facilitates processing and installation. The groove on the bottom surface of the bottom cover increases the structural strength of the bottom surface, prevents deformation of the bottom cover, ensures the overall structural strength of the volute, and thus ensures the structural strength of the supporting base.

[0022] Preferably, the volute and the base are secured by a snap-fit ​​assembly. This snap-fit ​​assembly facilitates assembly, improves assembly efficiency, reduces the number of fastening screws, and lowers costs.

[0023] Preferably, the side wall of the housing surrounds the heat dissipation channel and has an exhaust hole that is laterally corresponding to the outlet of the heat dissipation channel. The exhaust assembly also includes a baffle plate that extends vertically from the outlet of the heat dissipation channel to form a buffer space with the side wall of the housing.

[0024] By setting up a baffle plate, a buffer space can be formed between it and the side wall of the casing. This allows the airflow to be buffered when the airflow is too large or when the airflow is obstructed at the exhaust vent. This ensures that the airflow exiting from the heat dissipation channel exits smoothly from the exhaust vent, preventing airflow from flowing out through the gap between the side wall of the casing and the base, and reducing noise.

[0025] Preferably, the grinding cup is fixedly mounted on the machine body, and the food processing machine also includes a supply device that can communicate with the inner cavity of the grinding cup. The side wall of the machine housing protrudes outward to form a support platform for mounting the supply device, and the support platform covers the heat dissipation channel.

[0026] Food processing machines are also equipped with supply devices, such as water tanks or steam components, which enable the self-cleaning function of the food processing machine, achieving automation and multi-functionality. The side walls of the machine casing protrude to form a support platform, and the support platform covers the heat dissipation channel. Therefore, when the supply device is installed in the machine body, the supply device and the support platform further block the transmission of noise, thereby reducing noise.

Detailed Implementation

[0041] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples.

[0042] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figure 1 , Figure 2As shown, in one embodiment of the present invention, a food processing machine is provided, including a body 10 and a grinding cup 20 disposed on the body 10. The grinding cup 20 is provided with a grinding device 21, which is a grinding blade, or of course, a moving grinding head. The body 10 includes a housing 11, a motor 12 disposed in the housing 11, a cooling fan 13 disposed at the bottom of the motor 12, and an exhaust assembly 30. The motor 12 is used to drive the grinding device 21 to rotate. The exhaust assembly 30 is provided with a heat dissipation cavity 31 and a heat dissipation channel 32. The cooling fan 13 extends into the heat dissipation cavity 31. The heat dissipation channel 32 is arranged side by side on the side of the heat dissipation cavity 31 and communicates with the heat dissipation cavity 31. The heat dissipation channel 32 extends in a spiral shape.

[0044] The food processing machine provided in this application, such as Figure 1-3 As shown, the cooling fan 13 rotates within the cooling cavity 31, generating suction that drives airflow from top to bottom through the motor 12 into the cooling cavity 31. Figure 3 The solid arrow in the middle indicates the airflow direction. The airflow carries away the heat from the motor 12, achieving a cooling effect. The heat dissipation channel 32 is arranged side by side of the heat dissipation cavity 31 and is connected to the heat dissipation cavity 31. It can guide the airflow from the heat dissipation cavity 31 laterally into the heat dissipation channel 32 and discharge it to the outside. Therefore, the airflow direction changes from flowing from top to bottom to needing to bend laterally to enter the heat dissipation channel 32. During the process of entering the heat dissipation channel 32, the airflow path is tortuous, which prolongs the airflow path and avoids the airflow noise being directly discharged to the heat dissipation channel 32, thus achieving primary noise reduction. Moreover, during the process of the airflow entering the heat dissipation channel 32 laterally from the heat dissipation cavity 31, a large amount of wind pressure energy is consumed, which reduces the frequency of the wind pressure discharged to the outside and avoids high-frequency wind pressure howling noise, preventing the generation of harsh noise. The heat dissipation channel 32 extends in a spiral shape, further prolonging the airflow path and achieving secondary noise reduction, which reduces the noise generated by the cooling fan 13 and has a good noise reduction effect. Furthermore, this application achieves secondary noise reduction through the arrangement of the heat dissipation cavity 31 and the heat dissipation channel 32. Compared with the traditional method of setting baffles in the channel for noise reduction, this avoids affecting the airflow efficiency. Therefore, this application can achieve a balance between the overall heat dissipation effect and noise reduction effect of the exhaust component 30, reducing heat dissipation noise while ensuring good heat dissipation of the motor 12. On the other hand, the heat dissipation channel 32 is arranged side by side on the side of the heat dissipation cavity 31. In addition to reducing noise, it can also make reasonable use of the space inside the casing 11, and avoid increasing the height of the main unit, lowering the center of gravity of the main unit, and ensuring stable operation.

[0045] like Figure 2As shown, in a preferred embodiment, the bottom wall of the heat dissipation cavity 31 is not lower than the bottom wall 321 of the outlet end of the heat dissipation channel 32. Specifically, a horizontally extending plate-like structure can be provided in the space at the bottom of the cooling fan to form the bottom wall of the heat dissipation cavity 31, thereby raising the bottom wall of the heat dissipation cavity 31 and ensuring that the bottom wall of the heat dissipation cavity 31 is not lower than the bottom wall 321 of the outlet end of the heat dissipation channel. By setting the bottom wall of the heat dissipation cavity 31 to be not lower than the bottom wall 321 of the outlet end of the heat dissipation channel 32, the vertical stroke is expanded during the spiral flow of air in the heat dissipation channel 32, forming a larger height difference during the airflow process, thereby enhancing the noise reduction effect of the heat dissipation channel 32 on the airflow.

[0046] Of course, in another embodiment, the bottom wall of the heat dissipation cavity 31 is lower than that of the heat dissipation channel 32.

[0047] By making the bottom wall of the heat dissipation cavity 31 lower than the heat dissipation channel 32, the axial dimension of the heat dissipation cavity 31 is enlarged, thereby increasing the airflow and improving the heat dissipation effect of the motor 12.

[0048] The present invention does not limit the structure and shape of the heat dissipation cavity 31 and the heat dissipation channel 32. For example, in a preferred embodiment, such as Figure 3 As shown, the heat dissipation channel 32 is divided into an upper air duct 322 and a lower air duct 323. The upper air duct 322 forms the entrance to the heat dissipation channel 32, and the lower air duct 323 is connected to the lower air duct 322, so that the heat dissipation airflow is spirally discharged from top to bottom.

[0049] The heat dissipation channel 32 is divided into an upper air duct 322 and a lower air duct 323, forming an upper spiral air duct. After the airflow spirals through the upper air duct 322, it enters the lower air duct 323 and continues to spiral before being discharged to the outside. Therefore, the airflow undergoes two reversals when passing through the heat dissipation channel 32, resulting in a tortuous path and reduced noise. In addition, since the heat dissipation channel 32 and the heat dissipation cavity 31 are arranged in parallel, this arrangement allows the heat dissipation channel 32 to form a double layer within a limited space, reversing the airflow twice. This ensures noise reduction while making reasonable use of the internal space of the casing 11, resulting in a compact structure and avoiding an increase in the height of the main unit, thus reducing the overall height of the food processing machine.

[0050] Specifically, there are no restrictions on how the upper air duct 322 and the lower air duct 323 are formed; for example, ... Figure 1-8 As shown, in a preferred embodiment, the exhaust assembly 30 includes a base 33 and a volute 34 encapsulated at the bottom of the housing 11. The base 33 is provided with a mounting cavity 331, such as... Figure 3 and Figure 5 As shown, the volute 34 is installed in the mounting cavity 331, and together with the cavity wall 3311 of the mounting cavity 331, it defines the heat dissipation channel 32. Specifically, as shown... Figure 3In the middle, the interior of the volute 34 forms a lower air duct 323, and the top wall of the volute 34, together with the bottom wall and side wall of the mounting cavity 331, forms an upper air duct 322. The top of the mounting cavity 331 is provided with a notch for the cooling fan 13 to extend into, and the notch is laterally offset from the volute 34 to form a heat dissipation cavity 31 within the mounting cavity 331.

[0051] In this scheme, combined with Figure 3 The bottom wall of the mounting cavity 331 of the base 33 is used as part of the upper air duct 322 (top wall and side wall). The structure is reasonably utilized and the strength of the base 33 can be guaranteed. Of course, the present invention is not limited to this one. In fact, the upper air duct 322 and the lower air duct 323 can be directly defined by setting a partition in the inner cavity of the volute 34 itself.

[0052] Specifically, such as Figure 5 As shown, the volute 34 includes a housing 341 and a bottom cover 342 that is fastened to the bottom of the housing 341. The bottom surface of the bottom cover 342 is provided with a groove 3421.

[0053] The volute 34 is composed of a shell 341 and a bottom cover 342, which can be easily processed and installed. The bottom surface of the bottom cover 342 is provided with a groove to increase the structural strength of the bottom surface of the bottom cover 342, prevent the bottom cover 342 from deforming, ensure the overall structural strength of the volute 34, and thus ensure the structural strength of the supporting base 33.

[0054] As the main supporting component of the food processing machine, the base 33 requires greater structural strength. By setting the mounting cavity 331 in the base 33, the volute 34 and the base 33 form a heat dissipation channel 32 with good noise reduction effect. On the other hand, the volute 34 strengthens the structure of the base 33, prevents the base 33 from deforming, and ensures the strength of the base 33.

[0055] Specifically, the volute 34 and the base 33 are fixed together by a snap-fit ​​assembly 35. For example, a snap-fit ​​element 351 is provided on the volute 34 and a latching position 352 is provided on the base 33, which facilitates assembly, improves assembly efficiency, reduces the number of fastening screws, and lowers costs.

[0056] More specifically, such as Figure 6 and Figure 7 As shown, the shell 341 of the volute 34 integrally forms the bottom wall 311 of the heat dissipation cavity.

[0057] Combination Figure 6 and Figure 7 The exhaust assembly 30 includes a transition structure 36, which is connected between the heat dissipation cavity 31 and the inlet of the heat dissipation channel 32.

[0058] exist Figure 6In the preferred embodiment shown, the bottom wall of the heat dissipation cavity 31 is lower than the inlet bottom wall 324 of the heat dissipation channel 32, and the transition structure 36 includes an inclined flow guide plate that connects the bottom wall of the heat dissipation cavity 31 to the inlet bottom wall 324 of the heat dissipation channel 32.

[0059] Of course, the transition structure 36 in this invention is not limited to this one type. In fact, the transition structure 36 can be a channel structure. Furthermore, a slope can be provided on the top wall of the channel for drainage.

[0060] Since the airflow needs to bend laterally from the heat dissipation cavity 31 into the heat dissipation channel 32, the transition structure 36 can be set to make the airflow smoother, so as to ensure the smooth flow of airflow and achieve good heat dissipation effect while ensuring the noise reduction effect.

[0061] The bottom wall of the heat dissipation cavity 31 is lower than the bottom wall 324 of the inlet of the heat dissipation channel 32, which can make reasonable and effective use of the internal space of the casing 11. This ensures that the height of the heat dissipation cavity 31 is sufficient to accommodate the cooling fan 13 to increase the airflow, thereby improving the cooling effect of the motor 12. By setting a relatively high and inclined guide plate at the inlet of the heat dissipation channel 32, the heat dissipation channel 32 is ensured to have sufficient height. In this way, the airflow is maximized in the limited space inside the casing 11, and the airflow path is extended and flows smoothly, reducing noise.

[0062] In a preferred embodiment, the inner height of the heat dissipation cavity 31 is greater than the inlet height of the heat dissipation channel 32.

[0063] The heat dissipation cavity 31 is directly open on the side and connected to the inlet of the heat dissipation channel 32. Therefore, by adjusting the height of the bottom or top wall of the heat dissipation cavity 31, the inner height of the heat dissipation cavity 31 can be made greater than the inlet height of the heat dissipation channel 32. As a result, the airflow will encounter a reduction in the inlet cross-sectional area when it enters the heat dissipation channel 32 from the heat dissipation cavity 31, which will partially cancel out the airflow noise and further achieve a first-level noise reduction effect.

[0064] In a preferred embodiment, such as Figure 10 and Figure 11 As shown, the side wall of the housing 11 surrounds the heat dissipation channel 32 and is provided with an exhaust hole 111 that is laterally corresponding to the outlet of the heat dissipation channel 32. The exhaust assembly 30 also includes a baffle plate 37, which extends vertically from the outlet of the heat dissipation channel 32 to form a buffer space 38 between itself and the side wall of the housing 11.

[0065] By setting up the baffle plate 37, a buffer space 38 can be formed between it and the side wall of the housing 11. This allows the baffle plate 37 to buffer the airflow when it is too large or when the airflow is obstructed at the exhaust port 111. This ensures that the airflow exiting from the heat dissipation channel 32 can be smoothly discharged from the exhaust port 111, preventing the airflow from flowing out through the gap between the side wall of the housing 11 and the base 33, thus reducing noise.

[0066] Preferred, in Figure 1-11 In the embodiment shown, the grinding cup 20 is fixedly mounted on the machine body 10. The food processing machine also includes a supply device 40 that can communicate with the inner cavity of the grinding cup 20. The side wall of the housing 11 protrudes outward to form a support platform 112 for mounting the supply device 40. The support platform 112 covers the heat dissipation channel 32.

[0067] like Figure 10 As shown, in a preferred embodiment, the food processor is further provided with a supply device 40, such as a water tank, which enables the food processor to perform a self-cleaning function, achieving automation and multifunctionality. The supply device 40 can also be a steam component, etc., to heat the soy milk and dry it after cleaning. The side wall of the housing 11 protrudes to form a support platform 112, and the support platform 112 covers the heat dissipation channel 32. Therefore, when the supply device 40 is installed in the housing 10, the supply device 40 and the support platform 112 further block the transmission of noise, thereby reducing noise.

[0068] It should be noted that the cooling fan 13 in this application is a centrifugal fan, which has a larger suction force, increases the airflow for heat dissipation, and improves the heat dissipation effect. Alternatively, the cooling fan 13 can be an axial fan, which has a simple structure and ensures sufficient airflow.

[0069] Of course, the present invention is not limited to the food processing machine provided in the above embodiments. In the above embodiments, the food processing machine also includes a drain valve 70, a slurry receiving cup 50 and a residual water box 60 to realize automatic slurry discharge and automatic cleaning.

[0070] For example, in another embodiment, the food processor body 10 has a mounting platform for mounting the grinding cup 20, which is detachably mounted on the mounting platform. Users can easily remove the grinding cup 20 for convenient use. The mounting platform on the body 10 supports the grinding cup 20, and the detachable grinding cup 20 facilitates user operation. Especially for the flat body 10, which has a low height and large lateral dimensions, the parallel arrangement of the heat dissipation cavity 31 and heat dissipation channel 32 allows for efficient use of the internal space of the body 10, achieving a balance between heat dissipation and noise reduction. Furthermore, the detachable grinding cup 20 also enables multi-functional expansion of the body 10; pots and pans can be installed on the mounting platform. In this embodiment, the food processor can perform both grinding and pulping as well as cooking functions, achieving multiple uses in one machine.

[0072] The technical solutions protected by this invention are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this invention. Although the invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art.
