Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] Patent CN212438360U discloses a novel food processing machine, including a body with a radially outward protrusion on its upper part; a crushing container disposed within the body; a slurry discharge assembly, one end of which is connected to the crushing container and the other end forming a slurry discharge port; a slurry receiving cup disposed below the protrusion, the slurry discharge assembly being used to discharge the slurry prepared in the crushing container from the slurry discharge port into the slurry receiving cup; and a fan located above the slurry receiving cup for cooling the slurry in the slurry receiving cup, the fan being installed below the protrusion.

[0003] In this design, the fan blows air directly into the receiving cup. However, due to the centrifugal force generated by the fan's rotation, a portion of the airflow is lost due to centrifugal motion. Only a portion of the airflow reaches the receiving cup vertically. Furthermore, the fan is exposed below the protrusion or on the cup lid, making it impossible to concentrate the airflow. Therefore, the airflow utilization rate is low, the airflow speed is slow, affecting the slurry cooling efficiency, and the overall machine consumes unnecessary electrical energy and power due to the large airflow loss. Additionally, because the fan blows directly into the receiving cup, the steam generated by the hot slurry in the cup also flows directly to the fan, causing damage or shortening its lifespan, resulting in poor fan reliability. Utility Model Content

[0004] This invention provides a food processing machine to solve the problems of low cooling efficiency and poor fan reliability caused by using a fan to directly blow air onto the slurry for cooling in the prior art.

[0005] The technical solution adopted by this utility model is as follows: This utility model provides a food processing machine, including a main unit, a liquid receiving cup, a pulping chamber and a drain valve disposed in the main unit, the pulping chamber having a drain port, the drain valve being installed at the drain port for opening and closing the drain port, the drain valve including a dispensing nozzle, the dispensing nozzle discharging liquid toward the liquid receiving cup, the food processing machine also including a fan assembly and an air guide pipe disposed inside the main unit, the fan assembly including a concentrator nozzle, the concentrator nozzle being connected to the air guide pipe, so that the airflow blown out by the concentrator nozzle blows air toward the liquid receiving cup through the air guide pipe.

[0006] The food processing machine provided by this utility model, by incorporating a fan assembly and an air guide pipe inside the main unit, allows the fan assembly to be concealed within the main unit. After being guided by the air concentrator and air guide pipe, the air is directed towards the liquid receiving cup. This increases the distance between the fan assembly and the liquid receiving cup. While the main unit's casing prevents a large amount of steam from flowing directly towards the fan assembly, the concentrator and air guide pipe both extend the upward flow path of the steam and reduce the flow area, thus increasing the difficulty of steam flowing directly towards the fan assembly, reducing the amount of steam flowing towards the fan assembly, effectively protecting the fan assembly, extending its service life, and improving its reliability. Simultaneously, the airflow through the air guide pipe prevents dust from directly entering the fan assembly, further preventing dust from being blown into the liquid receiving cup, thus improving operational safety. In addition, the fan assembly is equipped with a concentrator nozzle and an air duct. The concentrator nozzle gathers the airflow from the fan, and the air duct guides the airflow outward. This not only accelerates the airflow velocity through the concentrator nozzle, but also reduces airflow loss by delivering the gathered airflow outward through the air duct. This allows for efficient utilization of the airflow in the fan assembly, improves the cooling efficiency of the slurry in the docking liquid cup, and accelerates bubble bursting during the heating and boiling process in the docking liquid cup, thus improving the anti-overflow effect and achieving efficient cooling and efficient anti-overflow effects.

[0007] In a preferred embodiment, the lower end of the air duct is connected to an air outlet, and the airflow blown out by the air concentrator blows into the liquid receiving cup through the air duct and the air outlet.

[0008] By connecting an air outlet to the lower end of the air duct, the airflow direction can be accurately controlled to guide the airflow more precisely to the wall of the liquid receiving cup or the liquid inside the liquid receiving cup, thereby achieving full and efficient utilization of the airflow of the fan assembly and improving the cooling effect.

[0009] More preferably, the air outlet is located above the opening of the liquid receiving cup and near the liquid outlet to blow air into the liquid inside the liquid receiving cup.

[0010] The air outlet is located above the opening of the liquid receiving cup and close to the liquid outlet. The airflow guided by the air duct can flow directly through the air outlet to the liquid. The airflow can directly carry away the heat of the liquid and improve the liquid cooling efficiency.

[0011] More preferably, the main unit has an installation sidewall located on the side of the liquid receiving cup and cooperating with the liquid receiving cup, and the air outlet is disposed on the installation sidewall to blow air onto the outer wall of the liquid receiving cup.

[0012] By placing the air outlet on the side wall of the mounting plate and blowing air onto the outer wall of the receiving cup, the vapor generated by the liquid in the receiving cup will not enter the air outlet or enter the fan assembly through the air duct, thus improving the reliability of the fan assembly. At the same time, the airflow blows towards the outer wall of the receiving cup, so even if the airflow carries dust, the dust will not directly enter the slurry and cause slurry contamination, thus improving food safety.

[0013] In a more preferred embodiment, the air outlet is fixed to the lower end of the air duct and extends out from the main unit;

[0014] By fixing the air outlet to the lower end of the air duct, the problem of airflow leakage and loss at the connection point between the air outlet and the air duct is eliminated, allowing for full utilization of the airflow of the fan assembly and improving cooling efficiency. While ensuring cooling performance, this also reduces the precision required for installation between the air duct and the main unit, making assembly of the air outlet and the main unit easier and more efficient. Furthermore, by having the air outlet extend from the main unit, the distance between the air outlet and the liquid receiving cup can be appropriately reduced, further enhancing cooling performance.

[0015] In another preferred embodiment, the air outlet is an air outlet hole opened on the main unit, and the lower end of the air guide pipe is connected to the air outlet hole.

[0016] Since the fan assembly and air duct are both located inside the main unit, the main unit needs to have an opening for airflow to be discharged. The air outlet is an air outlet hole opened on the main unit, so there is no need to install an additional air outlet, which simplifies the overall structure.

[0017] In a preferred embodiment, the food processing machine further includes a control valve for switching the on / off state of the air duct.

[0018] More preferably, the control valve shuts off as the outlet moves toward the receiving cup to discharge liquid.

[0019] By setting a control valve that shuts off during the discharge process from the outlet to the receiving cup, the steam generated by the slurry passing through the outlet and into the receiving cup is prevented from flowing back into the air collector and fan assembly, thus protecting the fan assembly and improving its reliability. At the same time, it reduces the impact on the smooth discharge of cold air caused by condensation in the air collector or duct.

[0020] More preferably, the control valve is a silicone sheet with slits;

[0021] By using a slit silicone sheet, the silicone sheet has good elasticity and sealing properties. When subjected to airflow pressure from the fan assembly, it can flexibly deform to open the slit and allow airflow to pass through. When no airflow passes through, it uses its own elasticity to return to the slit tightly closed, preventing steam backflow or dust from entering. The structure is simple and allows for flexible switching of the air duct.

[0022] Alternatively, more preferably, the control valve includes a valve plate with a vent hole and a spring plate for covering the vent hole, one end of the spring plate being hinged to the edge of the vent hole so as to be able to flip to open the vent hole.

[0023] Alternatively, or more preferably, by using a valve plate and a spring plate hinged together, the movement of the spring plate covers or opens the vent hole on the valve plate, which has a simple structure and reliable control.

[0024] Alternatively, the control valve may be a one-way valve or an electrically controlled valve installed in the air duct.

[0025] By employing one-way valves and electrically controlled valves, steam backflow into the air duct is effectively prevented, and precise control of airflow is achieved.

[0026] In a preferred embodiment, the fan assembly includes a fan and a mounting bracket for fixing the fan, wherein the concentrator nozzle is integrally formed on the mounting bracket;

[0027] Alternatively, the fan assembly includes a fan housing and fan blades, the fan housing having an air outlet, and the concentrator sleeve being fitted onto the air outlet;

[0028] Alternatively, the fan assembly includes a fan housing and fan blades, the fan housing having an air outlet, and the concentrator being integrally formed on the fan housing;

[0029] Depending on the fan assembly, the air concentrator can be formed on the mounting bracket, fan housing, or sleeved at the air outlet to reliably concentrate the airflow of the fan assembly, reduce airflow loss, and thus improve the cooling efficiency of the liquid in the docking cup.

[0030] In a preferred embodiment, the air-concentrating nozzle retracts toward the air guide duct and is provided with a circular interface that matches the air guide duct.

[0031] The concentrator nozzle contracts towards the air duct, forming a gradually narrowing airflow channel. This results in a gradually decreasing airflow area, increasing the airflow velocity as continuous airflow passes through, creating a stronger blowing effect. The circular interface makes connecting the air duct and the concentrator nozzle simple and effortless.

[0032] In a preferred embodiment, the food processing machine includes a filter element disposed in the air duct.

[0033] By installing a filter in the air duct, dust, particulate matter, and other impurities can be filtered out when the fan assembly blows air to prevent them from entering the liquid receiving cup, thus improving safety. At the same time, the filter can also prevent steam from flowing back into the fan assembly, protecting the fan assembly from moisture damage and improving its reliability.

[0034] The food processing machine also includes a control device that controls the fan assembly to operate when the drain valve is open. By controlling the fan assembly to operate when the drain valve is open, it is possible to simultaneously drain liquid and blow air for cooling, thereby accelerating the cooling of the slurry and improving cooling efficiency.

[0035] In a preferred embodiment, the air duct includes a first and a second branch pipe arranged vertically side by side, and the airflow blown out by the air concentrator blows the air to the liquid receiving cup through the first and second branch pipes.

[0036] By setting the air duct as a first split pipe and a second split pipe, the airflow blown out through the air concentrator is directed to different positions of the liquid receiving cup through the first split pipe and the second split pipe, thereby increasing the cooling area and improving the cooling efficiency.

[0037] More preferably, the air duct further includes an air collecting hood that is connected to the air concentrator nozzle. The air collecting hood is provided with a second interface and a third interface, which are respectively connected to the first diversion pipe and the second diversion pipe.

[0038] By setting up an air collector shroud, the airflow gathered by the air collector nozzles can enter the first and second split pipes through the transition of the air collector shroud. This eliminates the need to add additional air collector nozzles to the fan assembly, simplifying the structure of the fan assembly, while achieving airflow splitting, large-area cooling, and improving cooling efficiency.

[0039] More preferably, the receiving cup includes a receiving cup and a residual water box arranged side by side, the first diversion pipe blows air into the receiving cup, and the second diversion pipe blows air into the residual water box.

[0040] The first diversion pipe blows air into the receiving cup to cool the slurry or prevent it from overflowing, while the second diversion pipe blows air into the residual water box to cool the residual cleaning water, thus avoiding the risk of scalding the user when handling the residual water box directly after cleaning.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0060] like Figure 1As shown, in one embodiment of the present invention, a food processing machine is provided, including a main unit 10, a liquid receiving cup 20, a pulping chamber 30 disposed within the main unit 10, and a drain valve 40. The pulping chamber 30 is provided with a drain port, and the drain valve 40 is installed at the drain port for opening and closing the drain port. The drain valve 40 includes a liquid outlet 41, which drains liquid toward the liquid receiving cup 20. The food processing machine also includes a fan assembly 50 and an air guide duct 60 disposed inside the main unit 10. The fan assembly 50 includes a concentrator nozzle 53, which is connected to the air guide duct 60, so that the airflow blown out by the concentrator nozzle 53 blows air toward the liquid receiving cup 20 through the air guide duct 60.

[0061] The food processing machine provided by this utility model, by setting a fan assembly 50 and an air guide pipe 60 inside the main unit 10, allows the fan assembly 50 to be hidden inside the main unit 10. After being guided by the air concentrator 53 and the air guide pipe 60, the air is blown towards the liquid receiving cup 20, increasing the distance between the fan assembly 50 and the liquid receiving cup 20. While utilizing the housing of the main unit 10 to block a large amount of steam from flowing towards the fan assembly 50, the setting of the air concentrator 53 and the air guide pipe 60 both extends the upward flow path of the steam and reduces the flow area, thereby increasing the difficulty of steam flowing directly towards the fan assembly 50, reducing the amount of steam flowing towards the fan assembly 50, effectively protecting the fan assembly 50, extending its service life, and improving its reliability. At the same time, the air blowing from the fan assembly 50 through the air guide pipe 60 prevents dust from directly entering the fan assembly 50, further preventing dust from being blown into the liquid receiving cup 20, thus improving operational safety. In addition, the fan assembly 50 is equipped with a concentrator nozzle 53 and an air duct 60. The concentrator nozzle 53 gathers the airflow from the fan 51, and the air duct 60 guides the airflow outward. The concentrator nozzle 53 can accelerate the airflow speed, and the air duct 60 can transport the gathered airflow outward, reducing airflow loss. This allows the airflow of the fan assembly 50 to be used efficiently, improving the cooling efficiency of the slurry in the docking liquid cup 20, and accelerating the bursting of bubbles during the heating and boiling process of the docking liquid cup 20, thus improving the anti-overflow effect and achieving efficient cooling and efficient anti-overflow effect.

[0062] This invention does not limit the air blowing method from the air guide tube to the liquid receiving cup; it can be selected from either Embodiment 1 or Embodiment 2.

[0063] Implementation Method 1

[0064] like Figure 1-8 As shown, the air duct 60 blows air into the liquid receiving cup 20 through the liquid outlet 41. The liquid outlet 41 is used both to dispensing liquid and as an air outlet for cooling.

[0065] In this embodiment, a fan assembly 50 and an air duct 60 are installed inside the main unit 10, allowing the fan assembly 50 to be concealed within the main unit 10. After being guided by the air concentrator 53 and the air duct 60, the air is blown into the liquid receiving cup 20, increasing the distance between the fan assembly 50 and the liquid receiving cup 20. While the casing of the main unit 10 prevents a large amount of steam from flowing towards the fan assembly 50, the air concentrator 53 and the air duct 60 both extend the upward flow path of the steam and reduce the flow area, thereby increasing the difficulty of steam flowing directly towards the fan assembly 50, reducing the amount of steam flowing towards the fan assembly 50, and reducing dust accumulation, thus achieving effective protection for the fan assembly 50. This design extends the service life of the fan assembly 50 and improves its reliability and safety. Furthermore, the fan assembly 50 is equipped with a concentrator 53 and a guide duct 60. The concentrator 53 gathers the airflow from the fan, while the guide duct 60 directs the airflow outwards. This not only accelerates the airflow through the concentrator 53 but also reduces airflow loss by delivering the gathered airflow outwards through the guide duct 60. This ensures efficient utilization of the airflow in the fan assembly 50, improves the cooling efficiency of the slurry in the docking liquid cup 20, and accelerates bubble bursting during the heating and boiling process in the docking liquid cup 20, enhancing the anti-overflow effect and achieving both efficient cooling and anti-overflow capabilities.

[0066] In addition, the airflow blown out by the concentrator 53 of the fan assembly 50 passes through the air duct 60 and the liquid outlet of the drain valve to cool the liquid in the receiving cup 20. The airflow is guided out of the main unit 10 by the liquid outlet. When the fan assembly 50 blows air simultaneously during the liquid discharge process at the liquid outlet, it can further prevent steam from flowing back into the liquid outlet and the air duct 60, thereby preventing steam from entering the concentrator 53 and the air duct 60 to form condensate and hinder the discharge of cooling airflow, ensuring cooling efficiency and improving the reliability of the fan assembly 50. Moreover, there is no need to open additional holes on the main unit 10 for airflow discharge, so that the liquid outlet integrates the functions of liquid discharge and air blowing cooling. The structure is compact, the extension length of the air duct is shortened, and there is no need to open additional holes on the main unit 10 for cooling airflow discharge, simplifying the structure of the main unit 10 and reducing the production cost of the main unit 10.

[0067] Additionally, it should be noted that the specific connection method between the air guide 60 and the liquid outlet 41 is not limited in this utility model. For example, it can adopt any one of the embodiments 1-4:

[0068] Implementation Example 1, such as Figure 1-6 As shown, the drain valve 40 also includes a valve housing 42 and a valve core 43, as... Figure 5 As shown, the valve housing 42 has a first opening 421 connected to the drain port, a second opening 422 connected to the air duct 60, and a third opening 423 connected to the outlet nozzle 41.

[0069] like Figure 5As shown in this embodiment, the valve core 43 is a cylindrical valve core with a hollow interior. The cylindrical valve core has an upper port and a lower port at both ends, which correspond to the second opening 422 and the third opening 423, respectively. The second opening 422 and the third opening 423 are normally connected. Furthermore, the side of the cylindrical valve core is provided with a liquid passage corresponding to the first opening 421. Rotating the cylindrical valve core allows the first opening 421 to be connected to or closed with the drain port through the liquid passage.

[0070] This embodiment demonstrates that the air duct 60 and the liquid outlet are always connected, so that the fan assembly 50 can effectively blow airflow into the liquid receiving cup 20 to cool the liquid as soon as it is running. The cooling process is more direct and does not require additional valve structure or related control, thus improving exhaust smoothness and cooling efficiency.

[0071] Implementation Example 2, such as Figure 7 As shown, the drain valve 40 also includes a valve housing 42 and a valve core 43. The valve housing 42 has a first opening 421 connected to the drain port, a second opening 422 connected to the air duct 60, and a third opening 423 connected to the outlet nozzle 41.

[0072] Unlike Implementation Example 1, in this implementation example, as Figure 7 As shown, the valve core 43 is installed at the first opening 421 to control the connection or disconnection between the first opening 421 and the drain port. The valve core may include a movable valve plate rotatably disposed at the first opening 421 and a stationary valve plate fixed at the first opening 421. The stationary valve plate is provided with a connecting hole, and the movable valve plate rotates to open or cover the connecting hole. The first opening 421 is located downstream of the second opening 422, and the second opening 422 is normally connected to the third opening 423.

[0073] This embodiment still allows for constant connection between the air duct 60 and the liquid outlet. That is, no matter how the valve core rotates, the connection between the air duct 60 and the liquid outlet will not be affected. This allows the fan assembly 50 to effectively blow airflow into the liquid receiving cup 20 to cool the liquid. The cooling process is more direct and does not require additional valve structure or related control, thus improving exhaust smoothness and cooling efficiency.

[0074] Implementation Example 3, such as Figure 8 As shown, the drain valve 40 also includes a valve housing 42 and a valve core 43. The valve housing 42 has a first opening 421 connected to the drain port, a second opening 422 connected to the air duct 60, and a third opening 423 connected to the outlet nozzle 41.

[0075] Unlike Implementation Example 1, the valve core 43 is a hollow cylindrical valve core that rotates around its axis. The side wall of the valve core has a first inlet 431 and a second inlet 432 arranged circumferentially. The first inlet 431 and the second inlet 432 are respectively used to communicate with the drain port and the air duct 60. The end of the valve core has an outlet 433, and the slurry nozzle 41 is connected to the outlet 433. Rotating the valve core 43 allows the first inlet 431 to communicate with the drain port or the second inlet 432 to communicate with the air duct 60.

[0076] It is understood that in this embodiment, the first inlet 431 is connected to the drain outlet while the second inlet 432 is connected to the air duct 60; or, the first inlet 431 is connected to the drain outlet while the second inlet 432 is disconnected from the air duct 60.

[0077] In addition, based on this embodiment, an opening can be provided on the side wall of the valve core. The opening can serve as both a first inlet and a second inlet, so that the first inlet 431 is connected to the drain port while the second inlet 432 is staggered and shut off from the air duct 60, thereby reducing the impact of steam on the fan assembly.

[0078] In Example 4, the drain valve 40 also includes a valve housing and a valve core rotatably disposed within the valve housing. The valve core is a spherical valve core. The valve housing has a first opening connected to the drain port, a second opening connected to the air duct, and a third opening connected to the outlet nozzle. The spherical valve core selectively connects the first opening and the second opening to the third opening.

[0079] Optionally, in this embodiment, the ball valve core is provided with a communication channel, and the ball valve core rotates to use the communication channel to selectively connect the first opening and the second opening with the third opening;

[0080] Alternatively, the ball valve core may be provided with two connecting channels. The ball valve core may rotate to connect the first opening and the third opening using one connecting channel; the ball valve core may rotate to connect the first opening and the third opening using the other connecting channel.

[0081] By using a ball valve core to connect the first and second openings to the third opening, it is possible to selectively perform liquid discharge and air blowing. The ball valve core integrates liquid discharge control and air blowing control, thus integrating functions. At the same time, it avoids the situation where steam enters the air duct when the air duct and the liquid discharge port are connected at the same time, eliminating the need for a separate control valve to control the air duct's on / off state and simplifying the overall structure of the machine.

[0082] Furthermore, based on this embodiment, such as Figure 3 , 4 As shown, the receiving cup 20 includes a receiving cup 21 and a residual water box 22 arranged side by side. The dispensing nozzle moves relative to the valve housing, for example, by rotating or moving laterally, to a first position toward the receiving cup 21 (see reference). Figure 4) and the second position facing the residual water box 22 (refer to Figure 3 Switch between )

[0083] By setting up a slurry receiving cup 21 and a residual water box 22, and with the liquid outlet moving relative to the valve housing, the liquid outlet integrates both liquid dispensing and air blowing functions. It can not only cool the slurry in the slurry receiving cup 21, but also cool the residual cleaning water in the residual water box 22, thereby avoiding the risk of users getting their hands burned when directly taking the residual water box 22 after cleaning.

[0084] Implementation Method 2

[0085] like Figure 9 , 10 As shown, the lower end of the air duct 60 is connected to the air outlet 80, and the airflow blown out by the air concentrator 53 blows into the liquid receiving cup 20 through the air duct 60 and the air outlet 80.

[0086] In this embodiment, the air outlet 80 is set independently of the liquid outlet 41. By connecting the air outlet 80 to the lower end of the air duct 60, the air outlet direction can be accurately controlled to guide the airflow more accurately towards the wall of the liquid receiving cup 20 or the liquid inside the liquid receiving cup 20, thereby achieving full and efficient utilization of the airflow of the fan assembly 50 and improving the cooling effect.

[0087] In this embodiment, the present invention does not limit the blowing method of the air outlet 80. For example, the air outlet 80 can be selected from any one of the embodiments 5 and 6:

[0088] Implementation Example 5, such as Figure 9 , 10 As shown, the air outlet 80 is located above the opening of the liquid receiving cup 20 and near the liquid outlet 41 to blow air into the liquid inside the liquid receiving cup 20.

[0089] The air outlet 80 is located above the opening of the liquid receiving cup 20 and near the liquid outlet 41. The airflow guided by the air guide 60 can flow directly through the air outlet 80 to the liquid. The airflow can directly carry away the heat of the liquid and improve the liquid cooling efficiency.

[0090] Implementation Example 6, such as Figure 11 As shown, the main unit 10 has a mounting sidewall 101 located on the side of the liquid receiving cup 20 and cooperating with the liquid receiving cup 20. An air outlet 80 is provided on the mounting sidewall 101 to blow air onto the outer wall of the liquid receiving cup 20.

[0091] By placing the air outlet 80 on the mounting side wall 101 to blow air onto the outer wall of the receiving cup 20, the steam generated by the liquid in the receiving cup 20 will not enter the air outlet 80 due to the isolation of the outer wall of the receiving cup 20, nor will it enter the fan assembly 50 through the air guide 60, thereby improving the reliability of the fan assembly 50. At the same time, the airflow blows towards the outer wall of the receiving cup 20, so even if the airflow carries dust, the dust will not directly enter the slurry and cause slurry contamination, thus improving food safety.

[0092] Furthermore, in this embodiment, the installation position of the air outlet 80 is not limited; for example, it can be selected from any one of embodiments 7 and 8.

[0093] Implementation Example 7, refer to Figure 9 As shown, the air outlet 80 is an air outlet hole opened on the main unit 10, and the lower end of the air duct 60 is connected to the air outlet hole.

[0094] Since the fan assembly 50 and the air duct 60 are both located inside the main unit 10, the main unit 10 needs to have an opening for airflow to be discharged. The air outlet 80 is an air outlet hole opened on the main unit 10, so there is no need to install an additional air outlet 80, which simplifies the overall structure.

[0095] In Example 8, the air outlet 80 is fixed to the lower end of the air duct 60 and extends out from the main unit 10;

[0096] By fixing the air outlet 80 to the lower end of the air duct 60, the problem of airflow leakage and loss at the connection point between the air outlet 80 and the air duct 60 is eliminated, thus fully utilizing the airflow of the fan assembly 50 and improving the cooling effect. While ensuring cooling performance, this also reduces the installation precision required between the air duct 60 and the main unit 10, making the assembly of the air outlet 80 and the main unit 10 easier and more efficient. Furthermore, by having the air outlet 80 extend from the main unit 10, the distance between the air outlet 80 and the liquid receiving cup 20 can be reasonably reduced, further enhancing the cooling effect.

[0097] Implementation Example 9, such as Figure 12 As shown, in this embodiment, based on embodiment 7, the host 10 is provided with a connecting post 102, and the air outlet 80 is connected to the air outlet through the connecting post 102.

[0098] In this embodiment, preferably, refer to Figure 9 , 10As shown, the air duct 60 includes a first branch pipe 61 and a second branch pipe 62 arranged vertically side by side. The airflow blown out by the air concentrator 53 blows into the liquid receiving cup 20 through the first branch pipe 61 and the second branch pipe 62. More preferably, the air duct 60 also includes an air collecting hood 63 that is connected to the air concentrator 53. The air collecting hood 63 is provided with a second interface and a third interface, which are respectively connected to the first branch pipe 61 and the second branch pipe 62.

[0099] By setting the air duct 60 as the first branch pipe 61 and the second branch pipe 62, the airflow blown out through the air concentrator 53 is directed to different positions of the liquid receiving cup 20 through the first branch pipe 61 and the second branch pipe 62, thereby increasing the cooling area and improving the cooling efficiency.

[0100] Of course, it is understood that the air duct of this embodiment is not limited to the application in Embodiment 2, and can also be combined with Embodiment 1. In addition, the air duct in this utility model is not limited to the above-described air duct structure; in fact, the air duct can also be a single pipe.

[0101] By setting up the air collector shroud 63, the airflow gathered by the air collector nozzle 53 can enter the first split pipe 61 and the second split pipe 62 through the transition of the air collector shroud 63. There is no need to set up an additional air collector nozzle 53 on the fan assembly 50, which simplifies the structure of the fan assembly 50, while realizing air diversion, large-area cooling, and improving cooling efficiency.

[0102] Of course, in a more preferred embodiment, the receiving cup 20 includes a receiving cup 21 and a residual water box 22 arranged side by side, with a first diversion pipe 61 blowing air into the receiving cup 21 and a second diversion pipe 62 blowing air into the residual water box 22.

[0103] The first diversion pipe 61 blows air into the slurry cup 21 to cool the slurry or prevent it from overflowing. The second diversion pipe 62 blows air into the residual water box 22 to cool the residual cleaning water and prevent the user from directly touching the residual water box 22 after cleaning, thus avoiding the risk of scalding their hands.

[0104] In addition, in a preferred embodiment of the present invention, the food processing machine further includes a control valve for switching the on and off of the air duct 60, the control valve being shut off during the process of the liquid outlet draining towards the liquid receiving cup 20.

[0105] By setting a control valve, which shuts off during the discharge process from the outlet towards the receiving cup 20, the steam generated by the slurry passing through the outlet and flowing into the receiving cup 20 is prevented from flowing back into the air concentrator 53 and fan assembly 50, thus protecting the fan assembly 50 from moisture damage and extending its service life. At the same time, it reduces the impact on the smooth discharge of cold air caused by condensation in the air concentrator 53 or air duct 60.

[0106] It is understood that this embodiment can be combined with any of the embodiments one and two described above. When a control valve is preferably used in an embodiment where the air duct and the liquid outlet are normally connected, it is used to shut off the flow during the process of the liquid outlet draining towards the liquid receiving cup 20 to prevent steam from entering the air duct. In practice, the control valve can also be applied to other embodiments to further ensure shut-off during the process of the liquid outlet draining towards the liquid receiving cup 20, provided that the valve core can selectively connect the drain port and the air duct.

[0107] Regarding the specific structure of the control valve, optionally, the control valve is a silicone sheet with slits; or, the control valve includes a valve plate with vent holes and a spring plate for covering the vent holes, one end of the spring plate being hinged to the edge of the vent holes so as to be able to flip to open the vent holes; or, the control valve is a one-way valve or an electrically controlled valve installed in the air duct 60.

[0108] By employing a slit-shaped silicone sheet, which possesses excellent elasticity and sealing properties, the sheet can flexibly deform to open the slit under the airflow pressure of the fan assembly 50, allowing airflow to pass through. When no airflow passes, it elastically returns to its original position, tightly closing the slit to prevent steam backflow or dust ingress. The structure is simple, and the switching of the air duct 60 is flexible. By using a valve plate and spring plate hinged together, the spring plate moves to cover or open the vent holes on the valve plate. The structure is simple, and the control is reliable. The use of a one-way valve and an electrically controlled valve effectively prevents steam backflow into the air duct 60 and achieves precise control of airflow.

[0109] Of course, in another preferred embodiment, the food processing machine also includes a control device that controls the fan assembly to operate when the drain valve is open. This enables simultaneous draining and air cooling, accelerating slurry cooling and improving cooling efficiency.

[0110] It should also be noted that this utility model does not limit the specific structure of the fan assembly 50 or the corresponding location of the air concentrator 53. For example, refer to... Figure 2 As shown, in a preferred embodiment, the fan assembly 50 includes a fan 51 and a mounting bracket 52 for fixing the fan 51, with the concentrator nozzle 53 integrally formed on the mounting bracket 52.

[0111] In another embodiment, the fan assembly 50 includes a fan housing 51 and fan blades, the fan housing 51 is provided with an air outlet, and a concentrator 53 is sleeved on the air outlet.

[0112] In other embodiments, the fan assembly 50 includes a fan housing 51 and fan blades, the fan housing 51 having an air outlet, and a concentrator nozzle 53 integrally formed on the fan housing 51.

[0113] This invention is based on different fan components 50. The air concentrator 53 can be formed in the mounting bracket 52, the fan 51 housing, or sleeved at the air outlet to reliably concentrate the airflow of the fan component 50, reduce airflow loss, and thus improve the cooling efficiency of the liquid in the receiving liquid cup 20. Different fan components can be combined with any of the above embodiments one and two.

[0114] Furthermore, this utility model does not limit the structure of the air-concentrating nozzle 53, see reference. Figure 1 , 2 As shown, in a preferred embodiment, the concentrator nozzle 53 retracts toward the air duct 60 and has a circular interface that matches the air duct 60. Of course, the concentrator nozzle 53 can also be provided with a flat interface, and the air duct 60 is sleeved on the outer periphery of the flat interface.

[0115] The converging nozzle 53 contracts towards the air guide duct 60, forming a gradually narrowing airflow channel. This results in a gradually decreasing airflow area, increasing the airflow speed as continuous airflow passes through, creating a stronger blowing effect. The use of a circular interface makes connecting the air guide duct 60 and the converging nozzle 53 simple and effortless.

[0116] If the air concentrator 53 is equipped with a flat interface, the air duct 60 can be sleeved on the outer periphery of the flat interface, and the air duct 60 and the flat interface can be clamped together by the clamping structure to improve the connection reliability.

[0117] Regarding the mounting position of fan assembly 50, optionally, refer to... Figure 3 As shown, in a preferred embodiment, the fan assembly 50 is fixed to the outer wall of the pulping chamber 30. Specifically, in conjunction with Figure 2 , 3 As shown, a stud 31 is provided on the outer wall of the pulping chamber 30. Screws pass through the through hole of the mounting bracket 52 and are locked to the stud 31 to fix the mounting bracket 52 to the outer wall of the pulping chamber 30. Then, the fan 51 is snapped onto the mounting bracket 52 to complete the installation of the fan assembly. After installation, the air outlet of the fan 51 corresponds to the position of the air concentrator 53 provided on the mounting bracket 52.

[0118] Of course, in another preferred embodiment, the fan assembly 50 is fixed to the host 10.

[0119] By fixing the fan assembly 50 to the main unit 10, the fan assembly 50 is separated from the pulping chamber 30. This reduces the vibration transmitted to the fan assembly 50 during the pulverizing operation in the pulping chamber 30, reduces noise, and makes the fan assembly 50 more stable. By fixing the fan assembly 50 to the outer wall of the pulping chamber 30, the main unit 10 can be covered after the fan assembly 50 and the pulping chamber 30 are fixed together. This makes the installation of the fan assembly 50 visible, the installation position precise, and the assembly simple and labor-saving.

[0120] In a preferred embodiment, reference Figure 5 , 6 As shown, the food processing machine includes a filter element 70, which is a filter disc with a plurality of filter holes 71. The filter element 70 may be optionally installed at the connection between the air duct and the air concentrator or at the connection between the air duct and the drain valve.

[0121] By setting the filter element 70 and filter holes 71, dust, particulate matter and other impurities can be filtered when the fan assembly 50 blows air to prevent them from entering the liquid receiving cup 20; at the same time, the filter element 70 can also prevent steam from flowing back into the fan assembly 50, protecting the fan assembly 50 from moisture damage.

[0123] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
