Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a user-friendly food processing machine. Background Technology

[0002] Existing food processors typically consist of a main body, a cup assembly containing a built-in mixing element, and a motor located below the cup assembly that drives the mixing element. When using a food processor, the user places the ingredients into the mixing cup, and the mixing element rotates at high speed driven by the motor to process the ingredients. However, most models lack a heating function. After the ingredients, such as soy milk, are prepared, the user needs to heat them before drinking. To meet user needs, some manufacturers install a heating element below the mixing cup. During food processing, the heating element heats the mixing cup, thereby heating the ingredients inside, allowing the user to drink a relatively hot liquid. However, because the heated liquid is still quite hot, it cannot be drunk directly after being discharged to the outside; it needs to cool naturally to a suitable temperature before consumption. This waiting time is relatively long, especially for hot soy milk prepared before work in the morning, leading to a poor user experience. To address the aforementioned issues, the applicant previously proposed in patent CN110876570A a solution involving a cooling device installed between the shell and the mixing cup. Specifically, this cooling device cools the outer wall of the inner cup above the water level indicator. This allows the cooling device to remove a significant amount of heat from the lower layer of foam, preventing the air bubbles in the lower layer from expanding due to heat. Consequently, the upper layer of foam bubbles, under the influence of gravity, can self-squeeze the lower layer of foam bubbles, achieving self-defoaming and preventing overflow. While this solution primarily serves to defoam and prevent overflow, it also provides some cooling for the food. However, because the space between the shell and the mixing cup contains multiple components such as heating elements and control devices, it also dissipates heat from other components while cooling the mixing cup. Airflow is significantly obstructed as it passes through these components, resulting in slow airflow within the space and poor heat dissipation for the mixing cup. Users still need to wait a considerable amount of time before drinking, severely impacting the consumer experience. Utility Model Content

[0003] The purpose of this invention is to provide a convenient food processing machine to solve the problem that the temperature of the slurry is too high after it is prepared in existing food processing machines, making it unsuitable for direct consumption and requiring a long waiting time for heat dissipation.

[0004] To achieve the above objectives, this utility model provides a convenient food processing machine, including a machine body, a cup assembly disposed within the machine body and containing a stirring element, and a motor disposed below the cup assembly and driving the stirring element to rotate. The cup assembly includes a stirring cup and a heat dissipation duct communicating with the outside. The heat dissipation duct surrounds the outer periphery of the side wall of the stirring cup and is equipped with a cooling fan. The cup assembly includes an air guide cover disposed on the outer periphery of the side wall of the stirring cup. The heat dissipation duct includes a heat dissipation channel disposed within the air guide cover and an air inlet and an air outlet communicating with the outside.

[0005] This application designs the cup assembly as including a mixing cup and a heat dissipation duct connected to the outside environment. The heat dissipation duct surrounds the outer perimeter of the mixing cup's side wall, allowing for rapid heat dissipation of the food inside the mixing cup after processing. This quickly lowers the food temperature to a drinkable level, significantly reducing waiting time and improving the user experience. Simultaneously, a cooling fan is installed within the heat dissipation duct, rapidly increasing airflow across the mixing cup's surface and further enhancing heat dissipation efficiency and time. Furthermore, the heat dissipation duct isolates the mixing cup from the outside environment, providing noise reduction. Noise generated during food processing is attenuated within the duct before propagating outwards, further reducing noise transmission and improving the user experience.

[0006] Simultaneously, by configuring the heat dissipation airflow duct as a heat dissipation channel within the air guide shroud, along with an air inlet and outlet connecting the heat dissipation channel to the outside, when the cooling fan rotates and drives the airflow within the heat dissipation channel, the gas enters the heat dissipation channel through the air inlet, dissipating heat from the mixing cup before being discharged outwards through the air outlet. The air guide shroud can concentrate and guide the airflow, allowing more airflow to pass through the mixing cup, thereby further improving the heat dissipation effect on the mixing cup. This avoids the situation where the airflow guided by the cooling fan within the heat dissipation channel flows around, resulting in less airflow passing through the mixing cup and slower heat dissipation. Furthermore, the air guide shroud is located on the outer side wall of the mixing cup, isolating the mixing cup from the outside environment and reducing noise transmission to the outside.

[0007] In a preferred embodiment of a user-friendly food processing machine, the cooling fan includes an intake fan located at the air inlet and an exhaust fan located at the air outlet.

[0008] By configuring the cooling fan to include an intake fan at the air inlet and an exhaust fan at the air outlet, when cooling the mixing cup, not only can the intake fan draw air into the cooling channel, but the exhaust fan can also promptly expel the cooled airflow. This greatly increases the gas flow rate within the cooling channel, further enhancing the gas flow rate across the surface of the mixing cup per unit time, thereby improving cooling efficiency and shortening cooling time.

[0009] In a preferred embodiment of a user-friendly food processor, the air inlet and outlet are arranged tangentially along the outer wall of the mixing cup.

[0010] By setting the air inlet and outlet tangentially along the outer wall of the mixing cup, the airflow entering through the air inlet can flow directly along the side wall of the mixing cup. According to the Coanda effect, the airflow can adhere closely to the side wall of the mixing cup, thereby further improving the heat dissipation effect of the mixing cup and reducing the resistance to flow towards the air outlet. This helps to further improve the efficiency of airflow within the heat dissipation channel, and thus further improve the heat dissipation efficiency of the mixing cup.

[0011] In a preferred embodiment of a user-friendly food processor, the air inlet and air outlet are arranged radially opposite each other along the outer wall of the mixing cup.

[0012] By setting the air inlet and outlet radially opposite each other along the outer wall of the mixing cup, the airflow entering the heat dissipation channel through the air inlet can directly blow onto the mixing cup. At the same time, the airflow is split and flows to the side cavities of equal size and distance on both sides, and is discharged outward through the air outlet, thus forming a fast-flowing natural air channel, reducing mutual interference of airflow in the heat dissipation channel, thereby improving the efficiency of gas flow and heat dissipation.

[0013] In a preferred embodiment of a user-friendly food processor, a sensing element is provided on the bottom side wall of the mixing cup, and a guide shroud is provided with a clearance portion to avoid the sensing element.

[0014] By incorporating a clearance section in the air guide shroud to avoid the sensing element, the air guide shroud not only forms a heat dissipation channel but also avoids the sensing element. This isolates the sensing element from the side wall of the mixing cup, thus achieving heat insulation. This effectively prevents the air guide shroud from enclosing the sensing element in the heat dissipation channel, which would cause the heat generated during food processing to be directly conducted to the sensing element, leading to high temperatures that could cause the sensing element to age or even be damaged. This design protects the sensing element and extends its service life.

[0015] In a preferred embodiment of a user-friendly food processing machine, the air guide hood includes a first hood body and a second hood body arranged laterally opposite each other, the first hood body and the second hood body being joined together to form the air guide hood.

[0016] By configuring the air guide hood as including a first hood and a second hood arranged laterally opposite each other, and the first hood and the second hood being joined together to form the air guide hood, the air guide hood can be formed by assembling the first hood and the second hood laterally during assembly. Compared with the method of integral molding of the air guide hood, this not only reduces production costs, but also avoids the situation where large errors during production and assembly make it difficult or impossible to connect the air guide hood to the mixing cup, thus ensuring the smooth assembly of the whole machine.

[0017] In a preferred embodiment of a user-friendly food processor, a heat dissipation fin is provided inside the heat dissipation duct on the outer wall of the mixing cup, and the heat dissipation fin extends circumferentially along the side wall of the mixing cup.

[0018] By incorporating heat dissipation fins located on the outer wall of the mixing cup within the cooling duct, a larger contact area with the airflow is achieved, thereby increasing the airflow rate passing through the entire mixing cup per unit time and further enhancing the heat dissipation effect. Simultaneously, the heat dissipation fins extend circumferentially along the side wall of the mixing cup, allowing the airflow to follow the fins during flow, reducing the resistance of the fins to the airflow and further increasing the airflow rate.

[0019] In a preferred embodiment of a user-friendly food processor, multiple heat sinks are spaced apart along the axial direction of the mixing cup, and a heat dissipation gap is formed between two adjacent heat sinks.

[0020] By arranging multiple heat sinks at intervals along the axial direction of the mixing cup, and forming a heat dissipation gap between adjacent heat sinks, the contact area between the mixing cup and the airflow is further increased, thereby further increasing the airflow rate passing through the entire mixing cup per unit time, and thus further improving the heat dissipation effect.

[0021] In a preferred embodiment of a user-friendly food processing machine, the extension direction of the heat dissipation gap is the same as the airflow direction within the heat dissipation duct.

[0022] By aligning the extension direction of the heat dissipation gap with the airflow direction within the heat dissipation duct, the airflow can directly pass through the heat dissipation gap and flow rapidly, reducing the resistance of the heat sink to the airflow and helping to further improve the efficiency of gas flow, thereby further improving the heat dissipation efficiency.

[0032] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0033] 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.

[0034] like Figures 1 to 6As shown, this utility model provides a convenient food processing machine, including a machine body, a cup assembly with a built-in stirring element inside the machine body, and a motor 6 located below the cup assembly and driving the stirring element to rotate. The cup assembly includes a stirring cup 1 and a heat dissipation duct communicating with the outside. The heat dissipation duct surrounds the outer periphery of the side wall of the stirring cup 1 and is equipped with a cooling fan inside the heat dissipation duct. The cup assembly includes a wind guide shroud 2 covering the outer periphery of the side wall of the stirring cup 1. The heat dissipation duct includes a heat dissipation channel 9 located inside the wind guide shroud 2 and an air inlet 3 and an air outlet 8 communicating with the outside of the heat dissipation channel 9.

[0035] This application configures the cup assembly as including a mixing cup 1 and a heat dissipation duct connected to the outside, with the duct surrounding the outer perimeter of the side wall of the mixing cup 1. This allows for rapid heat dissipation of the food inside the mixing cup 1 after processing, quickly lowering its temperature to a drinkable level and significantly reducing waiting time, thus improving the user experience. Simultaneously, a cooling fan is installed within the heat dissipation duct, rapidly increasing airflow and significantly enhancing the gas flow rate across the surface of the mixing cup 1 per unit time, further improving heat dissipation efficiency and shortening cooling time. Furthermore, the heat dissipation duct isolates the mixing cup 1 from the outside environment, providing sound insulation and noise reduction. Noise generated during food processing is attenuated within the duct before propagating outwards, reducing noise transmission and further enhancing the user experience.

[0036] Meanwhile, by configuring the heat dissipation airflow duct as including a heat dissipation channel 9 located within the air guide shroud 2, and an air inlet 3 and an air outlet 8 connecting the heat dissipation channel 9 to the outside, when the cooling fan rotates and drives the airflow within the heat dissipation channel 9, the gas enters the heat dissipation channel 9 through the air inlet 3, dissipating heat from the stirring cup 1 before being discharged outwards through the air outlet 8. The air guide shroud 2 can concentrate and guide the airflow, allowing more airflow to pass through the stirring cup 1, thereby further improving the heat dissipation effect on the stirring cup 1 and preventing the airflow guided by the cooling fan to flow around in the heat dissipation channel 9, resulting in less airflow passing through the stirring cup 1 and slower heat dissipation. Furthermore, the air guide shroud 2 is installed on the outer side wall of the stirring cup 1, achieving isolation between the stirring cup 1 and the outside world, which can play a role in noise reduction and reduce the transmission of noise to the outside.

[0037] It should be noted that this application does not specifically limit the arrangement of the cooling fan. As shown in the figure, there is one cooling fan, located at the air outlet 8, and the air inlet 3 is located at the bottom of the air guide shroud 2. As a preferred embodiment of this application, such as... Figure 2 As shown, the cooling fan includes an intake fan 5 located at the air inlet 3 and an exhaust fan 7 located at the air outlet 8.

[0038] By configuring the cooling fans to include an intake fan 5 located at the air inlet 3 and an exhaust fan 7 located at the air outlet 8, when cooling the mixing cup 1, not only can the intake fan 5 bring air into the cooling channel 9, but the exhaust fan 7 can also promptly exhaust the cooled airflow. This greatly increases the gas flow rate within the cooling channel 9, further increasing the gas flow rate passing over the surface of the mixing cup 1 per unit time, thereby further improving the cooling efficiency and shortening the cooling time.

[0039] Furthermore, such as Figure 2 As shown, there are multiple air intake fans 5 or air outlet fans 7, which are arranged side by side along the axial direction of the mixing cup 1. More preferably, there are two air intake fans 5 and two air outlet fans 7. Of course, the two fans can also be arranged side by side in the horizontal direction, which will not be elaborated here.

[0040] It should also be noted that this application does not specifically limit the location of the air inlet 3 and the air outlet 8, which can be any of the following embodiments:

[0041] Example 1: As Figure 2 As shown, in this embodiment, the air inlet 3 and the air outlet 8 are arranged tangentially along the outer wall of the mixing cup 1. Specifically, the planes where the air inlet 3 and the air outlet 8 are located are parallel and located on opposite sides of the mixing cup 1. The vertical plane of the planes where the air inlet 3 and the air outlet 8 are located is the tangential plane of the outer wall of the mixing cup 1.

[0042] By setting the air inlet 3 and the air outlet 8 tangentially along the outer wall of the mixing cup 1, the airflow entering through the air inlet 3 can flow directly along the side wall of the mixing cup 1. According to the Coanda effect, the airflow can adhere closely to the side wall of the mixing cup 1, thereby further improving the heat dissipation effect of the mixing cup 1 and reducing the resistance to flow towards the air outlet 8. This helps to further improve the efficiency of airflow within the heat dissipation channel 9, and thus further improve the heat dissipation efficiency of the mixing cup 1.

[0043] Example 2: Figure 4 , Figure 5 As shown, in this embodiment, the air inlet 3 and the air outlet 8 are arranged radially opposite each other along the outer side wall of the stirring cup 1.

[0044] By setting the air inlet 3 and the air outlet 8 radially opposite each other along the outer wall of the stirring cup 1, the airflow entering the heat dissipation channel 9 through the air inlet 3 can directly blow onto the stirring cup 1. At the same time, the airflow is split and flows to the side cavities of equal size and distance on both sides, and is discharged outward through the air outlet 8, thereby forming a fast-flowing natural air channel, reducing the mutual interference of airflow in the heat dissipation channel 9, thereby improving the efficiency of gas flow and heat dissipation.

[0045] As a preferred embodiment of this application, such as Figure 1 As shown, the bottom side wall of the stirring cup 1 is provided with a sensing element 4, and the air guide shroud 2 is provided with a clearance part 21 to avoid the sensing element 4.

[0046] By providing a clearance part 21 for the sensing element 4 in the air guide shroud 2, the air guide shroud 2 can not only form a heat dissipation channel, but also avoid the sensing element 4 through the clearance part 21. At the same time, it can isolate the sensing element 4 from the side wall of the mixing cup 1, thereby achieving heat insulation. This effectively prevents the air guide shroud 2 from covering the sensing element 4 into the heat dissipation channel 9, which would cause the heat generated during food processing to be directly conducted to the sensing element 4, resulting in the sensing element 4 being prone to aging or even damage due to high temperature. This achieves the protection of the sensing element 4 and extends its service life.

[0047] It should be noted that this application does not specifically limit the structure of the air guide shroud 2. As one preferred embodiment of this application, such as... Figure 1 As shown, the air guide hood 2 includes a first hood 22 and a second hood 23 arranged laterally opposite each other. The first hood 22 and the second hood 23 are joined together to form the air guide hood 2. More preferably, as shown in the figure, the first hood 22 is provided with a plurality of protrusions arranged circumferentially, and the second hood 23 is provided with buckles that engage with the protrusions. The two are connected by the engagement of the buckles with the protrusions.

[0048] By configuring the air guide hood 2 to include a first cover 22 and a second cover 23 arranged laterally opposite each other, and the first cover 22 and the second cover 23 being joined together to form the air guide hood 2, the air guide hood 2 can be formed by assembling the first cover 22 and the second cover 23 laterally during the assembly of the air guide hood 2. Compared with the method of integral molding of the air guide hood 2, it can not only reduce the production cost, but also avoid the situation where the air guide hood 2 is difficult to connect with the stirring cup 1 or even cannot be connected due to large errors during production and assembly, thus ensuring the smooth assembly of the whole machine.

[0049] As a preferred embodiment of this application, such as Figure 3 As shown, a heat dissipation fin 10 is also provided in the heat dissipation duct, which is located on the outer wall of the stirring cup 1, and the heat dissipation fin 10 extends circumferentially along the side wall of the stirring cup 1.

[0050] By incorporating heat dissipation fins 10 located on the outer wall of the mixing cup 1 within the heat dissipation duct, a larger contact area with the airflow can be achieved, thereby increasing the airflow rate passing through the entire mixing cup 1 per unit time and further enhancing the heat dissipation effect. Simultaneously, the heat dissipation fins 10 extend circumferentially along the side wall of the mixing cup 1, allowing the airflow to follow the fins 10 during flow, reducing the resistance of the fins 10 to the airflow and further increasing the airflow rate.

[0051] Furthermore, such as Figure 3 As shown, multiple heat sinks 10 are spaced apart along the axial direction of the stirring cup 1, and a heat dissipation gap 101 is formed between two adjacent heat sinks 10.

[0052] By arranging multiple heat sinks 10 at intervals along the axial direction of the stirring cup 1, and forming a heat dissipation gap 101 between two adjacent heat sinks 10, the contact area between the stirring cup 1 and the airflow is further increased, thereby further increasing the airflow rate passing through the entire stirring cup 1 per unit time, and thus further improving the heat dissipation effect.

[0053] It should be noted that this application does not specifically limit the extension direction of the heat dissipation gap 101. As a preferred embodiment of this application, such as... Figure 3 As shown, the extension direction of the heat dissipation gap 101 is the same as the airflow direction in the heat dissipation duct.

[0054] By aligning the extension direction of the heat dissipation gap 101 with the airflow direction within the heat dissipation duct, the airflow can flow rapidly directly through the heat dissipation gap 101, reducing the resistance of the heat sink 10 to the airflow and further improving the efficiency of gas flow, thereby further enhancing the heat dissipation efficiency.

[0055] It should also be noted that this application does not specifically limit the relative relationship between the heat sink 10 and the mixing cup 1. The heat sink 10 and the mixing cup 1 can be integrally formed. For example, if the mixing cup 1 is made of metal, the heat sink 10 and the mixing cup 1 can be demolded at the same time. Alternatively, the heat sink 10 and the mixing cup 1 can be separately formed and then fixed together. For example, if the mixing cup 1 is made of glass and the heat sink 10 is made of metal.

[0056] The technical solutions protected by this utility model 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 utility model. Although this utility model 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. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
