Description

Technical Field

[0001] The embodiments of the present invention relate to the field of household appliance technology, and more specifically, to a food processor and a control method for the food processor. Background Technology

[0002] Currently, high-speed blenders are a type of cooking blender. The bottom wall of the cup is equipped with blades for crushing, which can make more delicate soy milk, crush various foods and cook them, making them an essential appliance in the family kitchen.

[0003] However, the blender cups in these technologies are very heavy, making them inconvenient to handle and difficult to clean. Furthermore, the lower part of the blades, the top lid, and the side walls of the blender cup are also difficult to clean thoroughly. Summary of the Invention

[0004] The embodiments of the present invention are intended to at least solve one of the technical problems existing in the prior art.

[0005] Therefore, a first aspect of the embodiments of the present invention provides a food processor.

[0006] A second aspect of the present invention provides a method for controlling a food processor.

[0007] In view of the above, according to a first aspect of the present invention, a food processor is provided, comprising: a mixing cup having a mixing chamber; a mixing element having at least a portion located within the mixing chamber and capable of rotating within the mixing chamber, the mixing element forming a rotating plane when rotating; and a spray cleaning device disposed at the bottom of the mixing cup and located within the projection of the rotating plane of the mixing element, the spray cleaning device being capable of spraying a cleaning medium into the mixing chamber.

[0008] The food processor provided in this embodiment of the invention includes a mixing cup, a mixing element, and a spray washing device. Specifically, the mixing cup is provided with a mixing chamber, which can accommodate food ingredients. The food processor also includes a driving element connected to the mixing element, so that the mixing element can rotate at high speed in the mixing chamber under the drive of the driving element to crush and mix the food ingredients in the mixing chamber, thereby realizing the preparation of food ingredients.

[0009] The food processor also includes a heating plate, which is located at the bottom of the blending cup and inside the container cavity. This allows the heating plate to heat the ingredients while the blending components are crushing and blending them, thus meeting the user's need for a multi-functional food processor, such as for making soy milk.

[0010] The mixing component can be a mixing blade, which includes multiple mixing blades spaced apart. Driven by a drive unit, these blades rotate at high speed, pulverizing and agitating the ingredients within the mixing chamber. The specific number of mixing blades can be set according to actual needs.

[0011] The spray cleaning device is located at the bottom of the mixing cup. When the mixing components rotate, they form a rotating plane. The spray cleaning device lies within the projection of this rotating plane and can spray cleaning media into the mixing chamber to clean both the mixing chamber and the mixing components. Understandably, because the spray cleaning device is located at the bottom of the mixing cup, when it sprays cleaning media into the mixing chamber, the media is sprayed upwards from the bottom of the mixing chamber. This allows for targeted cleaning of the mixing components, the side walls, bottom wall, and top wall of the mixing chamber, as well as hard-to-reach areas, improving the automatic cleaning effect of the food processor and thus enhancing the user experience.

[0012] In detail, when the cleaning medium is sprayed into the mixing chamber by the spraying device, the agitator can rotate within the mixing chamber, and the spraying device is located within the projection of the plane of rotation. Therefore, when the spraying device sprays the cleaning medium into the mixing chamber, the cleaning medium can come into contact with the agitator. Thus, when the agitator blades pass through the sprayed cleaning medium, the agitator can be cleaned. Moreover, when the agitator encounters the cleaning medium, it will rebound the cleaning medium against the bottom wall of the mixing chamber, thereby cleaning the bottom wall of the mixing chamber and the local areas and dead corners in contact with the bottom wall of the mixing chamber.

[0013] In addition, when the cleaning medium passes through the gap between two adjacent agitator blades, the agitator will drive the cleaning medium to rotate, thereby flushing the side wall and top wall of the agitator chamber, thus achieving a thorough cleaning of the agitator chamber.

[0014] In practical applications, when the automatic cleaning function of the food processor is activated, the drive unit rotates the mixing element, with the mixing element's speed ranging from 0 rpm to 1000 rpm. This rotation of the mixing element causes the cleaning medium to rotate, thereby impacting and cleaning the mixing chamber and improving the cleaning effect of the food processor. The specific speed of the mixing element can be set according to actual needs.

[0015] It should be noted that the cleaning medium can be water, and the specific setting can be made according to actual needs.

[0016] Specifically, the food processor also includes a water tank connected to a spray cleaning device. The water tank stores water used for preparing ingredients and cleaning the mixing chamber. When the food processor is started, the discharge valve closes the discharge channel, and water from the tank flows into the mixing chamber through the spray cleaning device. After the ingredients are prepared, the discharge valve opens, and the prepared slurry is discharged through the discharge channel. The discharge valve then closes. Cleaning of the mixing chamber begins. Water from the tank enters the mixing chamber through the spray cleaning device, effectively cleaning the mixing components, side walls, bottom wall, and top wall of the mixing chamber, as well as hard-to-reach areas. After one cleaning cycle, the discharge valve opens, and the cleaning wastewater is discharged through the discharge channel. This cleaning process can be repeated multiple times, for example, 2 to 4 times, to further improve the cleaning effect of the food processor, achieve a thorough cleaning of the mixing chamber, and enhance the user experience.

[0017] In addition, the food processor provided by the above-described technical solution of the present invention also has the following additional technical features:

[0018] In one possible technical solution, the spray washing device includes a nozzle and a nozzle orifice, wherein the nozzle orifice is disposed on the nozzle and communicates with the stirring chamber, the nozzle includes a first sidewall and a second sidewall located at the nozzle orifice and disposed opposite to each other, the first sidewall is disposed closer to the rotation center of the stirring member than the second sidewall, and the rotation direction of the stirring member is tangent to the first sidewall and / or the second sidewall.

[0019] In this technical solution, the spray cleaning device is defined as including a nozzle and a spray port. Specifically, the spray port is set on the nozzle and is connected to the mixing chamber. That is to say, the cleaning medium is sprayed into the mixing chamber through the spray port on the nozzle set at the bottom of the mixing chamber, thereby spraying and cleaning local areas and dead corners such as the mixing components, the side wall of the mixing chamber, the bottom wall of the mixing chamber, and the top wall of the mixing chamber, improving the automatic cleaning effect of the food processor and thus enhancing the user's experience of using the food processor.

[0020] Furthermore, the nozzle includes a first sidewall and a second sidewall, which are located at the nozzle opening and are arranged opposite to each other. The first sidewall is positioned closer to the rotation center of the stirring member than the second sidewall, meaning that the first and second sidewalls are arranged alternately from the inside out.

[0021] The direction of rotation of the agitator is tangent to the first sidewall and / or the second sidewall, meaning the first and / or second sidewalls are tangent to a circle centered on the agitator's rotation center. It is understood that there are infinitely many circles centered on the agitator's rotation center, including a first circle, which is tangent to the first sidewall. Also included are second circles with a different radius than the first circle, which are tangent to the second sidewall. In other words, the first sidewall can be tangent to a circle centered on the agitator's rotation center, and the second sidewall can also be tangent to a circle centered on the agitator's rotation center. Furthermore, the first and second sidewalls can be tangent to two separate circles centered on the agitator's rotation center with different radii.

[0022] Understandably, when the food processor activates its cleaning function, the mixing element rotates within the mixing chamber. By aligning the first and / or second sidewalls tangentially to the direction of rotation of the mixing element, the state of the cleaning medium ejected from the nozzle is made as consistent as possible with the flow of the cleaning medium driven by the mixing element. This reduces the impact between the cleaning medium ejected from the nozzle and the cleaning medium driven by the mixing element, ensuring effective cleaning of the mixing chamber and improving the cleaning effect. Furthermore, it also reduces the impact of the cleaning medium on the nozzle, extending the nozzle's lifespan.

[0023] In one possible technical solution, the stirring component includes multiple stirring blades, which form a rotating plane when rotating; along the axial direction of the stirring cup, the nozzle is higher than the bottom wall of the stirring cup and lower than the multiple stirring blades.

[0024] In this technical solution, the mixing element is defined as including multiple mixing blades, which form a rotating plane when rotated. Since the spraying device is located within the projection of the rotating plane, i.e., the nozzle is located within the projection of the rotating plane, the cleaning medium can contact the multiple mixing blades when it is sprayed into the mixing chamber through the nozzle. Thus, when the mixing blades pass through the sprayed cleaning medium, they are cleaned. Furthermore, when the mixing blades encounter the cleaning medium, they bounce the medium against the bottom wall of the mixing chamber, thereby cleaning the bottom wall of the mixing chamber and the areas and dead corners in contact with the bottom wall. In addition, when the cleaning medium passes through the gap between two adjacent mixing blades, the mixing blades drive the cleaning medium to rotate, flushing the side walls and top wall of the mixing chamber, thereby achieving a comprehensive and thorough cleaning of the mixing chamber.

[0025] Furthermore, along the axial direction of the mixing cup, the nozzle is higher than the bottom wall of the mixing cup and lower than the multiple mixing blades. In other words, along the axial direction of the mixing cup, the nozzle is located between the bottom wall of the mixing cup and the multiple mixing blades. On one hand, compared to placing the nozzle on the bottom wall of the mixing cup, this increases the height of the cleaning medium sprayed through the nozzle, expanding the cleaning range. On the other hand, placing the nozzle below the mixing blades, and closer to the mixing blades than placing it on the bottom wall of the mixing cup, increases the rebound force of the cleaning medium when it interacts with the mixing blades, thereby improving the cleaning effect on the bottom wall of the mixing chamber.

[0026] In one possible technical solution, the stirring blade includes a root portion and a tip portion arranged radially along the stirring cup; along the radial direction of the stirring cup, the nozzle is located at the middle position between the root portion and the tip portion and between the tip portion.

[0027] In this technical solution, the stirring blade is defined to include a root and a tip. Specifically, the root and tip are arranged radially along the stirring cup. It can be understood that the distance between the root and tip along the radial direction is the length of the stirring blade.

[0028] Furthermore, the nozzle is located at the midpoint between the root and tip of the blade and between the blade tip itself. This means that, with the rotation center of the agitator as the center, a first rotational plane is formed through the midpoint between the root and tip, and a second rotational plane is formed through the tip. The nozzle is located between the projections of the first and second rotational planes. This ensures that when cleaning media is sprayed into the agitation chamber through the nozzle, the cleaning media can contact multiple agitator blades, causing the blades to rotate and thus cleaning the inner wall of the agitation chamber.

[0029] It is understandable that if the nozzle is positioned close to the blade root, the cleaning medium sprayed through the nozzle cannot be driven to rotate as much as possible, thus reducing the cleaning effect. If the nozzle is located outside the projection of the plane of rotation, the cleaning medium cannot contact the agitator blades, which will also reduce the cleaning effect. By positioning the nozzle at the middle position between the blade root and the blade tip, and between the blade tip and the blade tip, it is ensured that when the cleaning medium is sprayed into the mixing chamber through the nozzle, the cleaning medium can contact multiple agitator blades, thereby driving the cleaning medium to rotate through the multiple agitator blades and spraying and cleaning the inner wall of the mixing chamber.

[0030] In one possible technical solution, along the radial direction of the mixing cup, the distance L1 between the nozzle and the rotation axis of the stirring component, the distance L2 between the nozzle and the blade tip, and the distance L3 between the nozzle and the inner wall of the mixing cup satisfy L2 < L3 < L1.

[0031] In this technical solution, along the radial direction of the mixing cup, the distance between the nozzle and the rotation axis of the mixing element is greater than the distance between the nozzle and the inner wall of the mixing cup, and the distance between the nozzle and the inner wall of the mixing cup is greater than the distance between the nozzle and the blade tip. This defines the approximate area where the nozzle is positioned radially along the mixing cup, ensuring that when cleaning media is sprayed into the mixing chamber through the nozzle, the cleaning media can contact multiple mixing blades. These blades then rotate the cleaning media, thereby spraying and cleaning the inner wall of the mixing chamber, improving the cleaning effect and operational stability of the food processor.

[0032] In practical applications, the distance between the nozzle and the inner wall of the mixing cup is greater than 5mm, and the specific distance can be set according to actual needs.

[0033] In one possible technical solution, along the axial direction of the mixing cup, the distance H1 between the nozzle and the multiple mixing blades satisfies 3mm≤H1≤20mm.

[0034] In this technical solution, the distance between the nozzle and the multiple stirring blades is between 3mm and 20mm along the axial direction of the stirring cup. That is, the distance between the nozzle and the multiple stirring blades is between 3mm and 20mm along the height direction of the stirring cup.

[0035] Understandably, if the distance between the nozzle and the multiple mixing blades is too large, meaning the blades extend too far into the mixing chamber, it reduces the rebound force of the cleaning medium sprayed from the nozzle, thus decreasing the cleaning effect. Furthermore, when processing food, due to gravity, most of the food tends to concentrate at the bottom of the mixing chamber; extending the blades too far will reduce the processing effectiveness. Additionally, recessing the nozzle into the bottom wall of the mixing chamber also increases the distance between the nozzle and the blades, creating more cleaning dead zones and further reducing cleaning efficiency.

[0036] If the distance between the nozzle and the multiple agitator blades is too small, the cleaning medium sprayed from the nozzle will have a greater impact on the blades, reducing their lifespan. It will also reduce the spray range of the cleaning medium after it bounces off the blades, decreasing the cleaning effect. Furthermore, a close distance between the nozzle and the blades can cause interference between the blades and the nozzle during operation, further reducing the lifespan of the cleaning device.

[0037] By maintaining a distance of 3mm to 20mm between the nozzle and multiple mixing blades, the cleaning effect of the spray device on the mixing chamber can be improved while ensuring the food processing effect of the food processor, thus ensuring the service life of the spray device and multiple mixing blades.

[0038] In one possible technical solution, along the axial direction of the stirring cup, the distance H2 between the multiple stirring blades and the top wall of the stirring chamber satisfies 100mm≤H2≤250mm.

[0039] In this technical solution, along the axial direction of the mixing cup, the distance between multiple mixing blades and the top wall of the mixing chamber is between 100mm and 250mm, that is, along the height direction of the mixing cup, the distance between multiple mixing blades and the top wall of the mixing chamber is between 100mm and 250mm.

[0040] Understandably, if the distance between the multiple mixing blades and the top wall of the mixing chamber is too large, it will increase the size of the food processor, raising production costs and making cleaning the mixing chamber more difficult. Furthermore, the height to which the cleaning medium is sprayed by the multiple mixing blades is limited. If the distance between the blades and the top wall of the mixing chamber is too large, it will reduce the amount of cleaning medium sprayed onto the top wall, thus reducing the cleaning effect.

[0041] If the distance between the multiple blades and the top wall of the mixing chamber is too small, it will reduce the volume of the mixing chamber, decrease the amount of food the food processor can handle, and lower the user experience. Furthermore, if the blades extend too far into the mixing chamber, the distance between them and the top wall will also be too small. It's understandable that when food is being processed, due to gravity, most of the food tends to concentrate in the lower part of the mixing chamber; extending the blades too far into the chamber would reduce the processing efficiency.

[0042] By spacing the multiple mixing blades between the top wall of the mixing chamber and the mixing blades between 100mm and 250mm, the cleaning effect of the mixing chamber and the processing effect of the food can be improved while ensuring the volume of the mixing chamber.

[0043] In one possible technical solution, along the axial direction of the mixing cup, the distance H1 between the nozzle and the multiple mixing blades, and the distance H2 between the multiple mixing blades and the top wall of the mixing chamber, satisfy 8≤H2 / H1≤60.

[0044] In this technical solution, the ratio of the distance between the multiple mixing blades and the top wall of the mixing chamber and the distance between the nozzle and the multiple mixing blades along the axial direction of the mixing cup is between 8 and 60. This optimizes the distance between the nozzle and the multiple mixing blades, as well as the distance between the multiple mixing blades and the top wall of the mixing chamber, thereby improving the cleaning effect of the mixing chamber while ensuring the size of the food processor.

[0045] In one possible technical solution, the distance m between the first sidewall and the second sidewall satisfies 0.01mm≤m≤1mm.

[0046] In this technical solution, the range of the distance between the first sidewall and the second sidewall is defined. Specifically, the distance between the first sidewall and the second sidewall is between 0.01mm and 1mm. That is, by setting the distance between the first sidewall and the second sidewall to be smaller, the spray area of ​​the nozzle is also set to be smaller, thereby generating greater pressure when the cleaning medium is sprayed through the nozzle, thus increasing the spray force and spray range of the cleaning medium, and making the cleaning of the mixing chamber and the mixing components more thorough.

[0047] In practical applications, water is used as the cleaning medium. By setting a small gap between the first and second sidewalls, effectively limiting the flow of the nozzle, a water pressure of 1 kPa to 70 kPa can be generated. The water, after being sprayed from the nozzle, forms a cone-shaped stream that hits the mixing element and bounces it back to the bottom of the mixing chamber. The rotation of the mixing element also drives the water flow, further scouring the sidewalls of the mixing chamber. Furthermore, due to the high water pressure, the sprayed water can also scour the top wall of the mixing chamber, i.e., the inner wall of the mixing cup lid, achieving a thorough, no-dead-angle cleaning of the mixing chamber and the mixing element, thus improving the automatic cleaning effect of the food processor.

[0048] The nozzle's flow-limiting effect allows the generated conical water flow to form a cone angle between 45° and 160°, ensuring thorough cleaning of the mixing chamber and mixing components. This washes away food residue adhering to the mixing chamber or mixing components, resulting in a more thorough cleaning of the mixing chamber.

[0049] In practical applications, the nozzle also includes a third sidewall and a fourth sidewall. The third and fourth sidewalls are located at the nozzle opening and are positioned opposite each other. The third sidewall is connected to the first and second sidewalls, and the fourth sidewall is connected to the first and second sidewalls, thus forming an "I"-shaped nozzle. Specifically, the distance between the third and fourth sidewalls can be between 4mm and 12mm, ensuring the nozzle's spray area, improving the water intake efficiency of the mixing chamber, and thus improving the food processor's preparation and cleaning efficiency. Simultaneously, it ensures the nozzle's flow-limiting effect, thereby ensuring the spray force of the cleaning medium and improving the cleaning effect.

[0050] In one possible technical solution, the nozzle further includes a third sidewall and a fourth sidewall located at the nozzle orifice and arranged opposite to each other. The third sidewall is connected to the first sidewall and the second sidewall, and the fourth sidewall is connected to the first sidewall and the second sidewall. The distance n between the third sidewall and the fourth sidewall satisfies 4mm≤n≤12mm.

[0051] In this technical solution, the nozzle further includes a third sidewall and a fourth sidewall, which are located at the nozzle opening and are positioned opposite each other. The third sidewall is connected to the first and second sidewalls, and the fourth sidewall is connected to the first and second sidewalls, thereby forming an "I"-shaped nozzle by the first, second, third, and fourth sidewalls. Specifically, the distance between the third and fourth sidewalls can be between 4mm and 12mm, thus ensuring the spray area of ​​the nozzle, improving the water intake efficiency of the mixing chamber, and thus improving the preparation and cleaning efficiency of the food processor. At the same time, it ensures the flow-limiting effect of the nozzle, thereby ensuring the spray force of the cleaning medium and improving the cleaning effect.

[0052] It is understandable that if the distance between the third and fourth sidewalls is too large, although the spray area of ​​the nozzle can be increased, the spray force of the cleaning medium will be reduced accordingly. If the distance between the third and fourth sidewalls is too small, although the spray force of the cleaning medium can be increased, the spray area of ​​the nozzle will be reduced, thus prolonging the food preparation and automatic cleaning time.

[0053] In one possible technical solution, the nozzle further includes a body and a limiting part, wherein the nozzle is disposed on the body, the limiting part is connected to the end of the body away from the nozzle, and the limiting part can be matched with the stirring cup for limiting.

[0054] In this technical solution, the nozzle is further defined as including a body and a limiting part. Specifically, the nozzle is set on the body, and the limiting part is connected to the end of the body away from the nozzle. The limiting part can cooperate with the mixing cup to limit the movement, thereby improving the installation stability of the nozzle and thus improving the stability of the food preparation and automatic cleaning process of the food processor.

[0055] It is understandable that the cleaning medium sprayed through the nozzle has a certain pressure due to the flow-limiting effect of the nozzle. If the nozzle installation is not stable, the nozzle may easily detach from the mixing cup when the cleaning medium is sprayed into the mixing chamber, resulting in leakage of food or cleaning medium in the mixing chamber and reducing the user experience.

[0056] By setting a limiting part to cooperate with the limiting part of the mixing cup, the installation stability and reliability of the nozzle are improved, thereby ensuring the stable operation of the food processor.

[0057] In practical applications, the main body and the limiting part are integrated into one structure, which can improve the connection strength between the main body and the limiting part and further enhance the installation stability of the nozzle.

[0058] In one possible technical solution, the food processor also includes a limiting groove, which is located on the outside of the mixing cup and the mixing chamber. The first end of the limiting part is connected to the main body, and the second end of the limiting part is inserted into the limiting groove.

[0059] In this technical solution, the food processor is further defined as including a limiting groove. Specifically, the limiting groove is set on the mixing cup and is located outside the mixing chamber. One end of the limiting part is connected to the main body, and the other end extends radially away from the nozzle so that the other end of the limiting part is inserted into the limiting groove, thereby limiting and cooperating with the limiting groove to improve the installation stability of the nozzle, and thus improve the stability of the food processor during food preparation and automatic cleaning.

[0060] It is understandable that the cleaning medium sprayed through the nozzle has a certain pressure due to the flow-limiting effect of the nozzle. If the nozzle installation is not stable, the nozzle may easily detach from the mixing cup when the cleaning medium is sprayed into the mixing chamber, resulting in leakage of food or cleaning medium in the mixing chamber and reducing the user experience.

[0061] By setting a limiting part and a limiting groove to limit the movement, the installation stability and reliability of the nozzle are improved, thereby ensuring the stable operation of the food processor.

[0062] In one possible technical solution, the nozzle is a flexible component; the food processor also includes a mounting hole that communicates with a limiting groove, and one end of the main body away from the limiting part extends into the mixing chamber through the mounting hole, with the main body abutting against the wall of the mounting hole.

[0063] In this technical solution, the food processor also includes a mounting hole. Specifically, the mounting hole communicates with the limiting groove, and one end of the main body facing away from the limiting part extends into the mixing chamber through the mounting hole. In other words, the mounting hole is connected to the mixing chamber. The end of the main body facing away from the limiting part extending into the mixing chamber, i.e., the end of the main body with the nozzle extending into the mixing chamber, facilitates the spraying of cleaning media into the mixing chamber through the nozzle. Specifically, the cleaning media is sprayed upwards from the bottom of the mixing chamber, thereby enabling thorough cleaning of the mixing components, the side walls of the mixing chamber, the bottom wall of the mixing chamber, and the top wall of the mixing chamber, as well as other areas and hard-to-reach spots. This improves the automatic cleaning effect of the food processor and enhances the user experience.

[0064] The nozzle is a flexible component, and its body abuts against the wall of the mounting hole, thereby forming a seal between the wall of the mounting hole and the body. This prevents food or cleaning media in the mixing chamber from leaking out through the gap between the wall of the mounting hole and the body, thus improving the user experience.

[0065] In practical applications, the nozzle is made of silicone, meaning it has a certain degree of elasticity, which improves the sealing effect between the mounting hole wall and the body.

[0066] In one possible technical solution, the body includes a spray washing section and a sealing section, wherein the nozzle is disposed in the spray washing section, the sealing section is located between the spray washing section and the limiting section and is connected to the spray washing section and the limiting section, and the sealing section abuts against the wall of the mounting hole; the spray washing section includes a first end and a second end, the first end of the spray washing section is disposed closer to the nozzle than the second end of the spray washing section, and along the height direction of the stirring cup, the thickness of the first end of the spray washing section is less than the thickness of the second end of the spray washing section.

[0067] This technical solution defines the main body as including a spraying section and a sealing section. Specifically, the nozzle is located in the spraying section, and the sealing section is located between the spraying section and the limiting section. One end of the sealing section is connected to the limiting section, and the other end is connected to the spraying section. The sealing section abuts against the wall of the mounting hole. This forms a seal between the wall of the mounting hole and the sealing section, preventing food or cleaning media in the mixing chamber from leaking through the gap between the wall of the mounting hole and the sealing section, thus improving the user experience.

[0068] The spray washing section includes a first end and a second end facing away from each other. The first end of the spray washing section is positioned closer to the nozzle than the second end, meaning the first end is connected to the sealing part, and the other end is located at the nozzle. Specifically, along the height direction of the mixing cup, the thickness of the first end of the spray washing section is less than the thickness of the second end. In other words, the thickness of the end of the spray washing section closer to the sealing part is set to be thicker, and the thickness of the end of the spray washing section located at the nozzle is set to be thinner, i.e., the thickness of the spray washing section is non-uniform.

[0069] By making the thickness of the end of the spray cleaning section near the sealing section thicker and the thickness of the end of the spray cleaning section at the nozzle thinner, the nozzle can effectively limit the flow at the nozzle to generate reasonable water pressure, while preventing the nozzle from breaking due to repeated opening and closing during the spraying of cleaning media, thus extending the service life of the nozzle.

[0070] In practical applications, the spraying section and the sealing section are integrated into one structure, which can improve the connection strength between the spraying section and the sealing section. Furthermore, it can prevent the spraying section from breaking due to repeated opening and closing when spraying the cleaning medium, thus extending the service life of the nozzle.

[0071] In one possible technical solution, the thickness d of the first end of the spray washing section satisfies 0.5mm≤d≤3.5mm.

[0072] In this technical solution, the thickness of the first end of the spraying section is between 0.5mm and 3.5mm along the height direction of the mixing cup. This ensures that the nozzle effectively limits the flow to generate reasonable water pressure while ensuring the structural strength of the first end of the spraying section and extending the service life of the nozzle.

[0073] It is understandable that if the thickness of the first end of the spray section is too thin, effective and reasonable water pressure cannot be generated at the nozzle, thereby reducing the spray force of the cleaning medium. If the thickness of the first end of the spray section is set to be thick, although effective flow restriction can be achieved, the spray area at the nozzle is small, which will reduce the efficiency of food preparation or cleaning of the mixing chamber.

[0074] By limiting the thickness of the first end of the spray section to between 0.5mm and 3.5mm, it is possible to ensure the structural strength of the first end of the spray section and extend the service life of the nozzle while ensuring effective flow restriction at the nozzle to generate reasonable water pressure.

[0075] It is understandable that when the cleaning medium is sprayed into the mixing chamber, the first end of the spray nozzle will open into the mixing chamber to increase the spray area of ​​the nozzle and ensure the efficiency of food preparation and mixing chamber cleaning.

[0076] In one possible technical solution, the included angle α between the side of the spray section facing the mixing chamber and the side of the spray section away from the mixing chamber satisfies 10°≤α≤45°.

[0077] In this technical solution, the side of the spray section facing the mixing chamber and the side of the spray section away from the mixing chamber form an angle between 10° and 45°. That is, at least one of the sides of the spray section facing the mixing chamber and the side away from the mixing chamber is an inclined plane. It is understood that the end of the spray section near the sealing part is thicker, and the end near the nozzle is thinner. Therefore, if the side of the spray section away from the mixing chamber is an inclined plane, this inclined plane is sloping upwards from the second end to the first end of the spray section. If the side of the spray section facing the mixing chamber is an inclined plane, this inclined plane is sloping downwards from the second end to the first end of the spray section. This results in a uniform change in the structure of the spray section, i.e., the thickness of the spray section gradually decreases from the second end to the first end. This ensures effective flow restriction at the nozzle to generate reasonable water pressure while preventing breakage due to repeated opening and closing of the spray section during the spraying of the cleaning medium, thus extending the service life of the nozzle.

[0078] In one possible technical solution, the food processor also includes a mounting connector and a water inlet pipe, wherein the mounting connector is located on the side of the nozzle away from the mixing chamber, and the water inlet pipe is connected to the mounting connector and can communicate with the nozzle.

[0079] This technical solution specifies that the food processor also includes a mounting connector and a water inlet pipe. Specifically, the mounting connector is located on the side of the nozzle away from the mixing chamber, and the water inlet pipe is connected to the mounting connector and can communicate with the nozzle. By setting the mounting connector, the water inlet pipe can be installed, thereby supplying water to the nozzle, and then spraying cleaning media into the mixing chamber through the nozzle. This allows for the spraying and cleaning of localized areas and hard-to-reach areas such as the mixing components, the side walls, bottom walls, and top walls of the mixing chamber, improving the automatic cleaning effect of the food processor and thus enhancing the user experience.

[0080] It's understandable that one end of the water inlet pipe can connect to the nozzle, and the other end can connect to a water source. Specifically, a water tank can be installed on the blender, with the other end of the water inlet pipe connected to the water tank via a pumping unit, improving the blender's level of automation and intelligence. Alternatively, the other end of the water inlet pipe can be connected to an external water source, thereby simplifying the blender's structure and reducing its production costs. The specific configuration can be determined based on actual needs.

[0081] In one possible technical solution, the food processor also includes a switch valve, which is located on the water inlet pipe and is used to control the opening and closing of the water inlet pipe.

[0082] In this technical solution, the food processor is also included as a switch valve. Specifically, the switch valve is installed on the water inlet pipe and can control the opening and closing of the water inlet pipe. In other words, the switch valve can control whether water is sprayed into the mixing chamber through the water inlet pipe and the nozzle, thereby facilitating the control of the food processor's operation and improving the user experience.

[0083] In addition, when the food processor is grinding and blending the ingredients in the mixing chamber, the switch valve closes, which prevents water from flowing back into the mixing chamber and ensures the effective preparation of the ingredients.

[0084] It is understandable that because the nozzle is a straight-line nozzle, that is, the distance between the first sidewall and the sidewall is small, it can prevent the food in the mixing chamber from leaking out of the nozzle.

[0085] In practical applications, the switch valve is a one-way valve, and the conduction direction of the one-way valve is one-way from the water inlet pipe to the nozzle, which simplifies the control process of the food processor and improves the user experience.

[0086] In one possible technical solution, the food processor also includes a water tank and a water pumping assembly, wherein the water pumping assembly is connected to the water inlet pipe and the water tank.

[0087] In this technical solution, the food processor is further defined as including a water tank and a water pumping component. Specifically, one end of the water pumping component is connected to the water inlet pipe, and the other end of the water pumping component is connected to the water tank.

[0088] Since the water inlet pipe is connected to the mixing chamber through the nozzle, when the water pumping component is working, water in the water tank can be pumped into the mixing chamber through the water inlet pipe, so as to realize the food processor's preparation of ingredients and cleaning of the mixing chamber.

[0089] By equipping the food processor with a water tank, it is easier to channel water from the tank into the mixing chamber, thus improving the ease of use and enhancing the fully automatic and intelligent level of the food processor.

[0090] In practical applications, the water pumping assembly includes a water pump and a water pumping pipe. A water outlet is set at the bottom of the water tank. One end of the water pumping pipe is connected to the water pump, and the other end is connected to the water outlet. Thus, when the water pump is working, the water in the water tank can be pumped through the water outlet, the water pumping pipe, and the water inlet pipe into the mixing chamber to achieve the preparation of food or the cleaning of the mixing chamber.

[0091] In one possible technical solution, the mixing cup includes a cup body and a lid, wherein the lid covers the top of the cup body and surrounds the cup body to form a mixing chamber.

[0092] In this technical solution, the mixing cup is defined as including a cup body and a lid. Specifically, the lid is placed on the top of the cup body. It is understood that the top of the cup body has an open end, and the lid is placed on the open end of the top of the cup body. Specifically, the lid is closable and can be placed on the open end of the top of the cup body, so that the user can place the ingredients to be prepared by opening the lid.

[0093] The lid and cup body enclose a mixing chamber, meaning the inner wall of the lid is the top wall of the mixing chamber. Since the spray cleaning device is located at the bottom of the mixing cup, when the spray cleaning device sprays the cleaning medium into the mixing chamber, the cleaning medium is sprayed upwards from the bottom of the mixing chamber. This allows for the spray cleaning of the mixing components, the side walls of the mixing chamber, the bottom wall of the mixing chamber, and the inner wall of the lid, as well as other localized and hard-to-reach areas. This improves the automatic cleaning effect of the food processor and enhances the user experience.

[0094] In one possible technical solution, the rotational speed R of the agitator satisfies 0 r / min ≤ R ≤ 1000 r / min.

[0095] In this technical solution, the rotation speed R of the stirring component is limited to between 0 r / min and 1000 r / min. When the automatic cleaning function of the food processor is activated, the stirring component can be driven to rotate by the drive component, and the rotation speed of the stirring component can be between 0 r / min and 1000 r / min. The rotation of the stirring component drives the cleaning medium to rotate, thereby impacting and cleaning the stirring chamber, thus improving the cleaning effect of the food processor.

[0096] In detail, when the cleaning medium is sprayed into the mixing chamber through the spraying device, the agitator rotates within the chamber. When the blades of the agitator pass through the sprayed cleaning medium, the agitator is cleaned. Furthermore, upon encountering the cleaning medium, the agitator rebounds the medium against the bottom wall of the mixing chamber, thus cleaning the bottom wall and the areas and dead corners in contact with it. Additionally, when the cleaning medium passes through the gap between adjacent blades of the agitator, the agitator drives the cleaning medium to rotate, flushing the side and top walls of the mixing chamber, thereby achieving a thorough cleaning of the mixing chamber.

[0097] In practical applications, when a food processor is preparing ingredients in the mixing chamber, the rotation speed of the mixing blades can be increased to achieve rapid preparation. The specific rotation speed can be set according to actual needs.

[0098] In one possible technical solution, the blending cup includes a dispensing port that communicates with the blending chamber; the food processor also includes a heating element, a first cup holder, and a second cup holder, wherein the heating element is located on the side of the blending cup away from the dispensing port, and a blending chamber is formed between the heating element and the blending cup; the first cup holder is located on the side of the heating element away from the blending chamber, and the second cup holder is located on the side of the blending cup away from the blending chamber, and the second cup holder is connected to the first cup holder; a portion of the blending cup and a portion of the heating element are sandwiched between the first cup holder and the second cup holder.

[0099] In this technical solution, the food processor is further defined as including a heating element, a first cup holder, and a second cup holder. Specifically, the blending cup has a pick-up and drop-out port that is connected to the blending chamber, allowing the user to remove ingredients from the blending chamber through the pick-up and drop-out port.

[0100] The heating element is located on the side of the mixing cup away from the dispensing / removing opening. A mixing chamber is formed between the heating element and the mixing cup; that is, the heating element and the mixing cup together form a mixing chamber. When food is inside the mixing chamber, it can directly contact the heating element, thereby improving heating efficiency. When the dispensing / removing opening of the mixing cup faces upwards, the heating element is located at the bottom of the mixing cup. The heating element can be directly connected to the mixing cup, or it can be indirectly connected to the mixing cup, thus forming the mixing chamber.

[0101] The first cup holder is located on the side of the heating element away from the stirring chamber, that is, the first cup holder is located on the outside of the heating element, and the inside of the heating element is used to form a stirring chamber together with the stirring cup.

[0102] The second cup holder is located on the side of the mixing cup away from the mixing chamber, that is, the second cup holder surrounds the outside of the mixing cup. Along the depth direction of the mixing cup, such as vertically, the second cup holder and the first cup holder can be reliably connected, forming a rigid whole. While the first and second cup holders are locked together, a portion of the heating element and a portion of the mixing cup abut against the first and second cup holders respectively. For example, when the first cup holder is positioned lower than the second cup holder, it provides upward support to the heating element, while the second cup holder applies downward pressure to the mixing cup. Under the combined action of the support provided by the first cup holder and the pressure applied by the second cup holder, the heating element and the mixing cup are clamped and fixed between the first and second cup holders.

[0103] The heating element and the stirring cup are fixed by the first cup holder and the second cup holder, so that the stirring cup and the heating element form a whole. The structure is simple and the assembly is ingenious, which can effectively reduce the difficulty of production and improve production efficiency.

[0104] In one possible technical solution, the first cup holder and the second cup holder are detachably connected by a locking connector.

[0105] In this technical solution, the first cup holder and the second cup holder are detachably connected by a locking connector. When the locking connector is removed from the first cup holder and the second cup holder, the first cup holder, the second cup holder, the heating element and the mixing cup are directly separable components. No other fastening connection is required between the components, which facilitates the disassembly and maintenance of the food processor.

[0106] In one possible technical solution, the food processor further includes a first flexible part and a second flexible part, wherein the first flexible part is disposed between the mixing cup and the heating element, and the second flexible part is disposed between the first cup base and the heating element.

[0107] In this technical solution, the food processor is further defined as including a first flexible part and a second flexible part. Specifically, when the mixing component rotates at high speed, the mixing cup will vibrate. Since the first flexible part is provided between the mixing cup and the heating element, the first flexible part realizes a soft connection between the heating element and the mixing cup, thereby slowing down the transmission of vibration generated at the mixing cup to the heating element side, reducing vibration transmission, and reducing the vibration of the entire food processor.

[0108] At the same time, it can also extend the service life of the heating element, avoid problems such as poor contact of the heating element caused by vibration transmitted to the heating element, and ensure the safe use performance of the heating element.

[0109] Furthermore, a second flexible part is provided between the first cup holder and the heating element to achieve a soft connection between the first cup holder and the heating element. This can further reduce the transmission of vibration generated at the mixing cup to the heating element and the first cup holder, weaken vibration transmission, and reduce the vibration of the entire food processor.

[0110] Optionally, the heating element includes a heating plate located at the bottom of the mixing cup.

[0111] In one possible technical solution, a portion of the stirring cup extends radially in a direction away from the central axis of the stirring cup to form a first limiting portion, and a portion of the heating element extends radially in a direction away from the central axis to form a second limiting portion; wherein, a portion of the second cup seat is disposed on the end face of the first limiting portion away from the second limiting portion, and a portion of the first cup seat is disposed on the end face of the second limiting portion away from the first limiting portion, so as to clamp and fix the stirring cup and the heating element.

[0112] In this technical solution, a portion of the stirring cup extends radially in a direction away from the central axis of the stirring cup to form a first limiting portion, that is, a portion of the stirring cup extends radially outward to form a first limiting portion, and the first limiting portion includes an end face away from the second limiting portion, that is, the upper end face of the first limiting portion.

[0113] A portion of the heating element extends radially in a direction away from the central axis to form a second limiting portion, that is, a portion of the heating element extends radially outward to form a second limiting portion, the second limiting portion including an end face away from the first limiting portion, that is, the lower end face of the second limiting portion.

[0114] The second cup holder applies a downward force to the stirring cup through the upper end of the first limiting part, while the first cup holder provides an upward supporting force to the heating element through the lower end of the second limiting part. Under the combined action of the downward force provided by the second cup holder and the upward supporting force provided by the first cup holder, the stirring cup and the heating element are reliably clamped between the first cup holder and the second cup holder.

[0115] Optionally, the first limiting part is an annular limiting frustum.

[0116] Optionally, the second limiting part is an annular limiting frustum.

[0117] In one possible technical solution, a portion of the second cup holder extends axially in the direction close to the heating element to form a third limiting portion, which is located on the radial side of the first limiting portion to restrict the radial movement of the stirring cup.

[0118] In this technical solution, a portion of the second cup holder extends axially towards the heating element to form a third limiting portion. Specifically, a portion of the second cup holder extends downwards to form the third limiting portion, which is located on the radial side of the first limiting portion, i.e., on the outer side of the stirring cup. The third limiting portion can contact the first limiting portion, thereby restricting the radial movement of the stirring cup. The first and second cup holders not only provide axial positional restriction for the stirring cup but also ensure its radial positional stability.

[0119] In one possible technical solution, the first cup holder includes a support portion and a fourth limiting portion, wherein the second limiting portion overlaps on the support portion, the fourth limiting portion is connected to the support portion and extends axially in a direction close to the first limiting portion, and the fourth limiting portion is located on the radial side of the second limiting portion to limit the radial movement of the heating element.

[0120] In this technical solution, the first cup holder includes a support portion and a fourth limiting portion. The second limiting portion overlaps the support portion, that is, the support portion is used to provide axial support force to the heating element. The fourth limiting portion is connected to the support portion and extends axially in a direction close to the first limiting portion, that is, the fourth limiting portion extends upward. The fourth limiting portion is located on the radial side of the second limiting portion. The fourth limiting portion can contact the second limiting portion of the heating element, thereby restricting the radial movement of the heating element.

[0121] In other words, in the axial direction, the first and second cup seats can clamp the heating element and the stirring cup, and in the radial direction, the third and fourth limiting parts can restrict the movement of the stirring cup and the heating element, thereby ensuring the positional stability of the heating element and the stirring cup.

[0122] In one possible technical solution, the second flexible part is installed on the heating element and then assembled in the first cup holder. The second cup holder is connected to the first cup holder by a locking connector. There is a receiving cavity between the first cup holder, the second cup holder and the heating element. The first flexible part is located in the receiving cavity and is disposed on the heating element. The stirring cup extends into the receiving cavity and contacts the second cup holder and the first flexible part respectively to form a cup assembly. The food processor also includes a housing and a vibration damping connector. The housing has an installation cavity. The cup assembly extends into the installation cavity and is connected to the housing by the vibration damping connector.

[0123] In this technical solution, during the assembly process of the food processor, the second flexible part can be installed on the heating element first. Specifically, the second flexible part includes a bottom rubber seat and a side gasket. The bottom rubber seat is installed on the bottom of the heating element, and the side gasket is installed on the side of the heating element, that is, the side gasket is installed on the second limiting part of the heating element.

[0124] Then, the heating element with the second flexible part is installed inside the first cup holder. As can be imagined, in order to meet the installation requirements of the heating element, the first cup holder has an installation space inside.

[0125] Next, the second cup holder is installed on the first cup holder using a locking connector. At this point, the first and second cup holders are fixed into a rigid body, and the rigid body has a receiving cavity inside.

[0126] Then, the first flexible part is placed inside the receiving cavity, and the first flexible part is located on the heating element. Next, the mixing cup is screwed into the second cup holder for fixation. At the same time, the first flexible part is also clamped by the mixing cup and the heating element, which not only seals the gap between the mixing cup and the heating element, but also allows the two to achieve a flexible connection, further improving the vibration reduction performance of the entire food processor. It is worth noting that the first cup holder, the second cup holder, the heating element, the mixing cup, the first flexible part, and the second flexible part are fixed into a whole, namely the cup body assembly.

[0127] During the assembly of the cup body assembly and the shell, the cup body assembly can be inserted into the shell from below, and then the cup body assembly and the shell can be fixed together by the vibration damping connector.

[0128] A vibration damping connector is provided between the shell and the cup assembly. The vibration damping connector allows the cup assembly to be suspended in the mounting cavity. That is, the cup assembly and the shell are connected only by the vibration damping connector, without any other rigid connection structure. Therefore, when the blender is working, the vibration damping connector can effectively reduce the vibration and noise of the cup assembly. The vibration damping connector relies on its own vibration damping performance to buffer the vibration and noise generated by the cup assembly, which significantly improves the vibration and noise of the blender as a whole.

[0129] According to a second aspect of the present invention, a control method for a food processor is provided. The food processor includes a mixing chamber, a discharge port, and a discharge valve. The discharge port is connected to the mixing chamber, and the discharge valve can control the opening and closing of the discharge port. The control method includes: controlling the discharge valve to close the discharge port; when the discharge valve is closed, controlling the water pumping component of the food processor to inject a first preset amount of liquid into the mixing chamber and complete the pulping; controlling the discharge valve to open the discharge port; when the discharge valve is open, controlling the discharge port to connect with a pulp receiving cup; after the pulping is completed, controlling the discharge valve to close the discharge port; when the discharge valve is closed, controlling the water pumping component to inject a second preset amount of liquid into the mixing chamber and controlling the mixing component of the food processor to rotate at a preset speed to clean the mixing chamber at least once; after cleaning, controlling the discharge valve to open the discharge port; when the discharge valve is open, controlling the discharge port to connect with a waste receiving cup.

[0130] The food processor provided in this embodiment of the invention includes a mixing chamber, a discharge port, and a discharge valve. Specifically, the mixing cup of the food processor has a mixing chamber, the discharge port is connected to the mixing chamber, and the discharge valve is disposed on the mixing cup and located at the discharge port to control the opening and closing state of the discharge port. It is understood that the food processor also includes a water tank and a water pumping assembly. The water tank is connected to the mixing chamber through the water pumping assembly, that is, water is supplied from the water tank to the mixing chamber through the water pumping assembly.

[0131] Before pulping, the discharge valve is closed and the discharge port is turned on. The water pumping unit is started to send the water in the water tank to the mixing chamber. Understandably, the mixing components of the food processor rotate at high speed under the drive of the food processor to beat the ingredients in the mixing chamber at high speed to make pulp.

[0132] After the pulping process is complete, the discharge valve opens the discharge port, and the pulp is collected in the receiving cup. It's understood that the food processor can include a receiving cup, or it can be a regular household cup. The specific configuration can be adjusted according to actual needs.

[0133] After the slurry is collected, close the discharge port by controlling the discharge valve and start cleaning the mixing chamber at least once.

[0134] Each time the machine is cleaned, the pumping unit is controlled to inject water into the mixing chamber, and the mixing components are controlled to rotate at a preset speed. During the rotation of the mixing components, water is sprayed and rotated in the mixing chamber, thereby spraying and cleaning the mixing components, the side walls, bottom walls, and top walls of the mixing chamber, improving the automatic cleaning effect of the food processor and enhancing the user experience.

[0135] After each cleaning cycle, control the discharge valve to open the discharge port and drain the wastewater from the mixing chamber into the waste collection cup. It's understood that the food processor may include a waste collection cup, which can also be a regular household cup. The specific settings can be configured according to actual needs.

[0136] It is understandable that the food processor includes a serving cup and a waste cup, with the serving cup located on top of the waste cup. Once the food is collected, the cleaning process can be initiated, improving the fully automatic and intelligent level of the food processor and thus enhancing the user experience.

[0137] The cleaning process should be repeated at least 2 to 4 times to further improve the cleaning effect of the mixing chamber.

[0138] It should be noted that during the pulping process, a first preset amount of liquid is injected into the mixing chamber. This first preset amount can be set according to the user's desired pulping concentration or different types of ingredients.

[0139] The second preset amount is the injection volume when cleaning the mixing chamber. It is set according to the size of the mixing chamber, etc. It is understood that the second preset amount and the first preset amount can be the same or different.

[0140] In addition, the control method for the food processor provided by the above-described technical solution of the present invention also has the following additional technical features:

[0141] In the above technical solution, further, the pumping component is controlled to inject a second preset amount of liquid into the mixing chamber, and the mixing component of the food processor is controlled to rotate at a preset speed. Specifically, this includes controlling the mixing component to rotate at a preset speed within a first preset time period after the pumping component starts injecting liquid into the mixing chamber.

[0142] In this technical solution, when the water pumping component injects liquid into the mixing chamber to clean it, the mixing component is controlled to rotate at a preset speed within a first preset time period after the water pumping component starts injecting liquid into the mixing chamber. In other words, the timing starts when the liquid is injected into the mixing chamber, and the mixing component is controlled to rotate within the first preset time period. This allows for rapid cleaning of the mixing chamber by the rotation of the mixing component, which in turn drives the liquid to flush and clean the mixing chamber, thus shortening the cleaning time of the mixing chamber and improving the user's experience of using the food processor.

[0143] In practical applications, the first preset time is less than or equal to 10 seconds, and further, the first preset time is less than or equal to 5 seconds, so as to start the stirring component to rotate as quickly as possible when injecting liquid into the stirring chamber, thereby improving the cleaning effect of the stirring chamber.

[0144] In the above technical solution, the first preset duration t further satisfies t≤10s.

[0145] In this technical solution, the first preset time is limited to less than or equal to 10 seconds. It is understandable that if the first preset time is longer, that is, more than 10 seconds after the water pumping component starts and injects liquid into the mixing chamber before controlling the mixing element to rotate, then the mixing chamber will already contain a certain amount of liquid, and the liquid level may even be higher than the mixing blades. This increases the driving force of the food processor's drive component to drive the mixing element and reduces the impact force of the mixing element rotating and scouring the liquid, thus reducing the cleaning effect.

[0146] By controlling the rotation of the agitator within 10 seconds of injecting liquid into the mixing chamber, the rotation of the agitator can be started as quickly as possible when the liquid is injected into the mixing chamber, ensuring the impact force of the liquid rotation driven by the agitator to improve the cleaning effect of the mixing chamber.

[0147] In the above technical solution, the first preset duration t further satisfies t≤5s.

[0148] In this technical solution, the first preset time is limited to less than or equal to 5 seconds. This can further shorten the start-up time of the agitator, that is, to start the agitator to rotate as quickly as possible when liquid is injected into the agitation chamber, ensuring the impact force of the liquid rotation driven by the agitator to scour, thereby improving the cleaning effect of the agitation chamber.

[0149] In the above technical solution, the preset rotational speed R further satisfies 0 r / min ≤ R ≤ 1000 r / min.

[0150] In this technical solution, the preset rotation speed R of the mixing element is limited to between 0 r / min and 1000 r / min. When the automatic cleaning function of the food processor is activated, the mixing element can be driven to rotate by the drive element, and the rotation speed of the mixing element can be between 0 r / min and 1000 r / min. The rotation of the mixing element drives the liquid injected into the mixing chamber to rotate, thereby impacting and cleaning the mixing chamber and improving the cleaning effect of the food processor.

[0151] In practical applications, when a food processor is preparing ingredients in the mixing chamber—that is, when the food processor is making a puree—the rotation speed of the mixing components can be increased to achieve rapid preparation of the ingredients. The specific rotation speed can be set according to actual needs.

[0152] In the above technical solution, the food processor further includes a spray washing device located at the bottom of the mixing chamber. The spray washing device controls the water pumping component to inject a second preset amount of liquid into the mixing chamber. Specifically, it controls the water pumping component to spray a second preset amount of liquid into the mixing chamber through the spray washing device.

[0153] In this technical solution, the food processor also includes a spray cleaning device, which is located at the bottom of the mixing chamber. While the water pumping component injects liquid into the mixing chamber to clean it, the spray cleaning device sprays liquid into the mixing chamber. It is understood that because the spray cleaning device is located at the bottom of the mixing chamber, when it sprays liquid into the mixing chamber, the liquid is sprayed upwards from the bottom of the mixing chamber. This allows for thorough cleaning of the mixing components, the side walls, bottom wall, and top wall of the mixing chamber, as well as other hard-to-reach areas, improving the automatic cleaning effect of the food processor and thus enhancing the user experience.

[0154] It is worth noting that the spraying device is located within the projection of the plane of rotation formed when the agitator rotates, so that when the spraying device sprays liquid into the agitator chamber, the liquid can come into contact with the agitator.

[0155] In detail, when liquid is sprayed into the mixing chamber through the spraying device, the agitator rotates within the chamber. As the agitator blades pass through the sprayed liquid, they are cleaned. Furthermore, upon encountering the liquid, the agitator deflects it against the bottom wall of the mixing chamber, thus cleaning the bottom wall and the areas in contact with it, including hard-to-reach spots. Additionally, when the liquid passes through the gap between adjacent agitator blades, the agitator rotates the liquid, flushing the side and top walls of the mixing chamber, achieving a thorough and comprehensive cleaning.

[0156] Additional aspects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0170] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0171] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0172] The following reference Figures 1 to 10 This describes a food processor 100 and a method for controlling the food processor according to some embodiments of the present invention.

[0173] Example 1:

[0174] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the first aspect of the present invention provides a food processor 100, which includes: a mixing cup 110, the mixing cup 110 having a mixing chamber 113; a mixing element 120, at least a portion of which is located within the mixing chamber 113 and is rotatable within the mixing chamber 113, forming a rotating plane when the mixing element 120 rotates; and a spray cleaning device 130, located at the bottom of the mixing cup 110 and within the projection of the rotating plane of the mixing element 120, capable of spraying a cleaning medium into the mixing chamber 113.

[0175] The food processor 100 provided in this embodiment of the invention includes a mixing cup 110, a mixing element 120, and a spray washing device 130. Specifically, the mixing cup 110 is provided with a mixing chamber 113, which can accommodate food ingredients. The food processor 100 also includes a driving element connected to the mixing element 120. Under the drive of the driving element, the mixing element 120 can rotate at high speed in the mixing chamber 113 to crush and mix the food ingredients in the mixing chamber 113, thereby realizing the preparation of food ingredients.

[0176] The food processor 100 also includes a heating plate, which is located at the bottom of the mixing cup 110 and inside the receiving cavity. This allows the heating plate to heat the food while the mixing element 120 is crushing and blending it, thus meeting the user's needs for the multi-functional use of the food processor 100, such as the preparation of soy milk.

[0177] The mixing element 120 can be a mixing blade, which includes multiple mixing blades 121. The multiple mixing blades 121 are spaced apart, so that under the drive of the driving element, the multiple mixing blades 121 rotate at high speed and crush and mix the ingredients in the mixing chamber 113. The specific number of mixing blades 121 can be set according to actual needs.

[0178] The spray cleaning device 130 is located at the bottom of the mixing cup 110. When the mixing element 120 rotates, it forms a rotating plane. The spray cleaning device 130 is located within the projection of the rotating plane and can spray cleaning medium into the mixing chamber 113 to clean the mixing chamber 113 and the mixing element 120. It is understood that because the spray cleaning device 130 is located at the bottom of the mixing cup 110, when the spray cleaning device 130 sprays cleaning medium into the mixing chamber 113, the cleaning medium is sprayed upwards from the bottom of the mixing chamber 113. This allows for thorough cleaning of the mixing element 120, the side walls of the mixing chamber 113, the bottom wall of the mixing chamber 113, and the top wall of the mixing chamber 113, as well as cleaning of hard-to-reach areas. This improves the automatic cleaning effect of the food processor 100 and enhances the user experience of the food processor 100.

[0179] In detail, when the cleaning medium is sprayed into the mixing chamber 113 by the spraying device 130, the agitator 120 can rotate within the mixing chamber 113, and the spraying device 130 is located within the projection of the plane of rotation. Therefore, when the spraying device 130 sprays the cleaning medium into the mixing chamber 113, the cleaning medium can contact the agitator 120. Thus, when the agitator blades 121 of the agitator 120 pass through the sprayed cleaning medium, the agitator 120 can be cleaned. Moreover, when the agitator 120 encounters the cleaning medium, it will bounce the cleaning medium against the bottom wall of the mixing chamber 113, thereby cleaning the bottom wall of the mixing chamber 113 and the local areas and dead corners in contact with the bottom wall of the mixing chamber 113. In addition, when the cleaning medium passes through the gap between two adjacent stirring blades 121 of the stirring element 120, the stirring element 120 will drive the cleaning medium to rotate to flush the side wall and top wall of the stirring chamber 113, thereby achieving a thorough cleaning of the stirring chamber 113.

[0180] In practical applications, when the automatic cleaning function of the food processor 100 is activated, the drive unit can drive the mixing element 120 to rotate. The rotation speed of the mixing element 120 can be between 0 r / min and 1000 r / min. The rotation of the mixing element 120 drives the cleaning medium to rotate, thereby impacting and cleaning the mixing chamber 113, thus improving the cleaning effect of the food processor 100. The specific rotation speed of the mixing element 120 can be set according to actual needs.

[0181] It should be noted that the cleaning medium can be water, and the specific setting can be made according to actual needs.

[0182] Specifically, the food processor 100 also includes a water tank 210, which is connected to a spray washing device 130. The water tank 210 stores water for preparing ingredients and cleaning the mixing chamber 113. When the food processor 100 is started, the discharge valve of the food processor 100 closes the discharge channel, and the water in the water tank 210 flows into the mixing chamber 113 through the spray washing device 130. After the ingredients are prepared, the discharge valve opens and the prepared slurry is discharged through the discharge channel, and then the discharge valve closes. Cleaning of the mixing chamber 113 begins. The water in the water tank 210 enters the mixing chamber 113 through the spray washing device 130. When the water is sprayed into the mixing chamber 113 through the spray washing device 130, it can effectively clean the mixing components 120, the side walls of the mixing chamber 113, the bottom wall of the mixing chamber 113, and the top wall of the mixing chamber 113, as well as other areas and hard-to-reach spots. After one cleaning cycle, the discharge valve is opened, and the cleaning wastewater is discharged from the discharge channel. The above cleaning process can be performed multiple times, for example, 2 to 4 times, to further improve the cleaning effect of the food processor 100, achieve thorough cleaning of the mixing chamber 113, and enhance the user's experience of using the food processor 100.

[0183] Example 2:

[0184] like Figure 1 , Figure 2 and Figure 3 As shown, based on the above embodiment, the spray washing device 130 further includes a nozzle 131 and a spray port 132, wherein the spray port 132 is disposed on the nozzle 131 and communicates with the stirring chamber 113. The nozzle 131 includes a first sidewall and a second sidewall located at the spray port 132 and disposed opposite to each other. The first sidewall is disposed closer to the rotation center of the stirring member 120 than the second sidewall. The rotation direction of the stirring member 120 is tangent to the first sidewall and / or the second sidewall.

[0185] In this embodiment, the spray cleaning device 130 is defined to include a nozzle 131 and a nozzle 132. Specifically, the nozzle 132 is disposed on the nozzle 131 and is connected to the mixing chamber 113. That is, the cleaning medium is sprayed into the mixing chamber 113 through the nozzle 132 disposed on the nozzle 131 at the bottom of the mixing chamber 113. This allows for spray cleaning of local areas and dead corners such as the mixing component 120, the side wall of the mixing chamber 113, the bottom wall of the mixing chamber 113, and the top wall of the mixing chamber 113, thereby improving the automatic cleaning effect of the food processor 100 and enhancing the user's experience with the food processor 100.

[0186] Furthermore, the nozzle 131 includes a first sidewall and a second sidewall, which are located at the nozzle 132 and are arranged opposite to each other. The first sidewall is positioned closer to the rotation center of the agitator 120 than the second sidewall, meaning that the first and second sidewalls are arranged alternately from the inside out.

[0187] The direction of rotation of the agitator 120 is tangent to the first sidewall and / or the second sidewall, meaning the first sidewall and / or the second sidewall are tangent to a circle centered on the rotation center of the agitator 120. It is understood that there are infinitely many circles centered on the rotation center of the agitator 120, including a first circle tangent to the first sidewall. Also included are second circles with radii different from the first circle, tangent to the second sidewall. In other words, the first sidewall can be tangent to a circle centered on the rotation center of the agitator 120, and the second sidewall can also be tangent to a circle centered on the rotation center of the agitator 120. Furthermore, the first and second sidewalls can be tangent to two separate circles centered on the rotation center of the agitator 120 with different radii.

[0188] Understandably, when the food processor 100 activates its cleaning function, the mixing element 120 rotates within the mixing chamber 113. By tangenting the first and / or second sidewalls to the rotation direction of the mixing element 120, the state of the cleaning medium ejected through the nozzle 132 is kept as consistent as possible with the flow state of the cleaning medium driven by the mixing element 120. This reduces the impact between the cleaning medium ejected through the nozzle 132 and the cleaning medium driven by the mixing element 120, ensuring effective cleaning of the mixing chamber 113 and improving the cleaning effect. Furthermore, it also reduces the impact of the cleaning medium on the nozzle 131, extending the service life of the nozzle 131.

[0189] like Figure 1 As shown, based on the above embodiment, the stirring member 120 further includes a plurality of stirring blades 121, which form a rotating plane when rotating; along the axial direction of the stirring cup 110, the nozzle 132 is higher than the bottom wall of the stirring cup 110 and lower than the plurality of stirring blades 121.

[0190] In this embodiment, the stirring element 120120 is defined as including a plurality of stirring blades 121, which can form a rotating plane when rotated. Since the spraying device 130 is located within the projection of the rotating plane, that is, the nozzle 132 is located within the projection of the rotating plane, when the cleaning medium is sprayed into the stirring chamber 113 through the nozzle 132, the cleaning medium can contact the plurality of stirring blades 121. Thus, when the stirring blades 121 pass through the sprayed cleaning medium, the stirring blades 121 can be cleaned. Moreover, when the stirring blades 121 encounter the cleaning medium, they will bounce the cleaning medium against the bottom wall of the stirring chamber 113, thereby cleaning the bottom wall of the stirring chamber 113 and the local areas and dead corners in contact with the bottom wall of the stirring chamber 113 by the cleaning medium bounced by the stirring blades 121. In addition, when the cleaning medium passes through the gap between two adjacent stirring blades 121, the stirring blades 121 will drive the cleaning medium to rotate to flush the side wall and top wall of the stirring chamber 113, thereby achieving a thorough cleaning of the stirring chamber 113.

[0191] Furthermore, along the axial direction of the mixing cup 110, the nozzle 132 is higher than the bottom wall of the mixing cup 110 and lower than the plurality of stirring blades 121. That is, along the axial direction of the mixing cup 110, the nozzle 132 is located between the bottom wall of the mixing cup 110 and the plurality of stirring blades 121. On the one hand, compared to setting the nozzle 132 on the bottom wall of the mixing cup 110, the height of the cleaning medium sprayed through the nozzle 132 can be increased, expanding the cleaning range. On the other hand, setting the nozzle 132 below the stirring blades 121, and closer to the stirring blades 121 than setting the nozzle 132 on the bottom wall of the mixing cup 110, can increase the rebound force of the cleaning medium when it comes into contact with the stirring blades 121, thereby improving the cleaning effect on the bottom wall of the mixing chamber 113.

[0192] like Figure 3 As shown, based on the above embodiment, the stirring blade 121 further includes a root portion 1211 and a tip portion 1212 arranged radially along the stirring cup 110; along the radial direction of the stirring cup 110, the nozzle 132 is located at the middle position of the root portion 1211 and the tip portion 1212 and between the tip portion 1212.

[0193] In this embodiment, the stirring blade 121 is defined to include a root portion 1211 and a tip portion 1212. Specifically, the root portion 1211 and the tip portion 1212 are arranged radially along the stirring cup 110. It can be understood that the distance between the root portion 1211 and the tip portion 1212 in the radial direction is the length of the stirring blade 121.

[0194] Furthermore, the nozzle 132 is located at the middle position of the blade root 1211 and the blade tip 1212, and between the blade tip 1212. It can be understood that, with the rotation center of the stirring member 120 as the center, a first rotational plane is formed through the middle position of the blade root 1211 and the blade tip 1212, and a second rotational plane is formed through the blade tip 1212. The nozzle 132 is located between the projections of the first and second rotational planes. This ensures that when cleaning medium is sprayed into the stirring chamber 113 through the nozzle 132, the cleaning medium can contact the multiple stirring blades 121, thereby causing the cleaning medium to rotate and thus spray cleaning onto the inner wall of the stirring chamber 113.

[0195] It is understandable that if the nozzle 132 is positioned close to the blade root 1211, the cleaning medium sprayed through the nozzle 132 cannot be driven to rotate more effectively, thus reducing the cleaning effect. If the nozzle 132 is located outside the projection of the plane of rotation, the cleaning medium cannot contact the stirring blades 121, which also reduces the cleaning effect. By positioning the nozzle 132 at the middle position between the blade root 1211 and the blade tip 1212, it is ensured that when the cleaning medium is sprayed into the stirring chamber 113 through the nozzle 132, the cleaning medium can contact multiple stirring blades 121, thereby driving the cleaning medium to rotate and cleaning the inner wall of the stirring chamber 113.

[0196] like Figure 3 As shown, based on the above embodiment, further, along the radial direction of the stirring cup 110, the distance L1 between the nozzle 132 and the rotation axis of the stirring member 120, the distance L2 between the nozzle 132 and the blade tip 1212, and the distance L3 between the nozzle 132 and the inner sidewall of the stirring cup 110 satisfy L2 < L3 < L1.

[0197] In this embodiment, along the radial direction of the mixing cup 110, the distance between the nozzle 132 and the rotation axis of the mixing element 120 is greater than the distance between the nozzle 132 and the inner wall of the mixing cup 110, and the distance between the nozzle 132 and the inner wall of the mixing cup 110 is greater than the distance between the nozzle 132 and the blade tip 1212. This defines a general area for the nozzle 132 along the radial direction of the mixing cup 110, thereby ensuring that when cleaning medium is sprayed into the mixing chamber 113 through the nozzle 132, the cleaning medium can contact the multiple mixing blades 121, causing the cleaning medium to rotate and thus spray cleaning onto the inner wall of the mixing chamber 113, improving the cleaning effect and operational stability of the food processor 100.

[0198] In practical applications, the distance between the nozzle 132 and the inner wall of the mixing cup 110 is greater than 5mm, and can be set according to actual needs.

[0199] like Figure 1 As shown, based on the above embodiment, further, along the axial direction of the stirring cup 110, the distance H1 between the nozzle 132 and the plurality of stirring blades 121 satisfies 3mm≤H1≤20mm.

[0200] In this embodiment, the distance between the nozzle 132 and the plurality of stirring blades 121 along the axial direction of the stirring cup 110 is between 3 mm and 20 mm. That is, along the height direction of the stirring cup 110, the distance between the nozzle 132 and the plurality of stirring blades 121 is between 3 mm and 20 mm.

[0201] Understandably, if the distance between the nozzle 132 and the multiple mixing blades 121 is too large, meaning the multiple mixing blades 121 extend into the mixing chamber 113 to a high degree, on the one hand, the rebound force of the multiple mixing blades 121 against the cleaning medium sprayed from the nozzle 132 is reduced, thus decreasing the cleaning effect. On the other hand, when the food processor 100 processes food, due to gravity, most of the food is concentrated in the lower part of the mixing chamber 113. Extending the multiple mixing blades 121 into the mixing chamber 113 to a high degree will reduce the processing effect on the food. In addition, recessing the nozzle 132 into the bottom wall of the mixing chamber 113 will also increase the distance between the nozzle 132 and the multiple mixing blades 121, which will increase the cleaning dead areas and thus reduce the cleaning effect.

[0202] If the distance between the nozzle 132 and the multiple mixing blades 121 is too small, i.e., the distance between the nozzle 132 and the multiple mixing blades 121 is too close, the cleaning medium sprayed from the nozzle 132 will have a greater impact force on the multiple mixing blades 121, reducing the service life of the multiple mixing blades 121. Furthermore, it will also reduce the spray range of the cleaning medium after rebounding from the multiple mixing blades 121, reducing the cleaning effect. In addition, if the distance between the nozzle 132 and the multiple mixing blades 121 is too close, the multiple mixing blades 121 are prone to interference with the nozzle 131 during the operation of the food processor 100, thereby reducing the service life of the spray washing device 130.

[0203] By keeping the distance between the nozzle 132 and the multiple mixing blades 121 between 3mm and 20mm, the cleaning effect of the spray cleaning device 130 on the mixing chamber 113 can be improved while ensuring the food processing effect of the food processor 100, thus ensuring the service life of the spray cleaning device 130 and the multiple mixing blades 121.

[0204] like Figure 1 As shown, based on the above embodiment, further, along the axial direction of the stirring cup 110, the distance H2 between the plurality of stirring blades 121 and the top wall of the stirring chamber 113 satisfies 100mm ≤ H2 ≤

[0205] 250mm.

[0206] In this embodiment, along the axial direction of the stirring cup 110, the distance between the plurality of stirring blades 121 and the top wall of the stirring chamber 113 is between 100mm and 250mm, that is, along the height direction of the stirring cup 110, the distance between the plurality of stirring blades 121 and the top wall of the stirring chamber 113 is between 100mm and 250mm.

[0207] Understandably, if the distance between the multiple mixing blades 121 and the top wall of the mixing chamber 113 is too large, it will increase the size of the food processor 100, increasing its production cost and making the cleaning of the mixing chamber 113 more difficult. Furthermore, the height to which the cleaning medium is sprayed by the multiple mixing blades 121 is limited. If the distance between the multiple mixing blades 121 and the top wall of the mixing chamber 113 is too large, it will reduce the amount of cleaning medium sprayed onto the top wall of the mixing chamber 113, thereby reducing the cleaning effect on the top wall of the mixing chamber 113.

[0208] If the distance between the multiple mixing blades 121 and the top wall of the mixing chamber 113 is too small, on the one hand, it will reduce the volume of the mixing chamber 113, reduce the amount of food processed by the food processor 100, and reduce the user experience. On the other hand, if the multiple mixing blades 121 extend into the mixing chamber 113 to a high height, the distance between the multiple mixing blades 121 and the top wall of the mixing chamber 113 will also be too small. It is understandable that when the food processor 100 processes food, the food is mostly concentrated in the lower part of the mixing chamber 113 due to gravity. Extending the multiple mixing blades 121 into the mixing chamber 113 to a high height will reduce the processing effect on the food.

[0209] By keeping the distance between the multiple stirring blades 121 and the top wall of the stirring chamber 113 between 100mm and 250mm, the cleaning effect of the stirring chamber 113 and the processing effect of the food can be improved while ensuring the volume of the stirring chamber 113.

[0210] In a specific embodiment, further, along the axial direction of the stirring cup 110, the distance H1 between the nozzle 132 and the plurality of stirring blades 121, and the distance H2 between the plurality of stirring blades 121 and the top wall of the stirring chamber 113 satisfy 8≤H2 / H1≤60.

[0211] In this embodiment, along the axial direction of the mixing cup 110, the ratio of the distance between the plurality of mixing blades 121 and the top wall of the mixing chamber 113 and the distance between the nozzle 132 and the plurality of mixing blades 121 is between 8 and 60, thereby optimizing the distance between the nozzle 132 and the plurality of mixing blades 121, as well as the distance between the plurality of mixing blades 121 and the top wall of the mixing chamber 113, thereby improving the cleaning effect of the mixing chamber 113 while ensuring the product size of the food processor 100.

[0212] like Figure 2 As shown, based on the above embodiment, the distance m between the first sidewall and the second sidewall further satisfies 0.01mm≤m≤1mm.

[0213] In this embodiment, the range of the distance between the first sidewall and the second sidewall is defined. Specifically, the distance between the first sidewall and the second sidewall is between 0.01 mm and 1 mm. That is, by setting the distance between the first sidewall and the second sidewall to be smaller, the spray area of ​​the nozzle 132 is also set to be smaller, so that when the cleaning medium is sprayed through the nozzle 132, a larger pressure can be generated, thereby increasing the spray force and spray range of the cleaning medium, and making the stirring chamber 113 and the stirring element 120 more thoroughly cleaned.

[0214] In practical applications, water is used as the cleaning medium. By setting a small gap between the first and second sidewalls, i.e., limiting the flow of the nozzle 131, a water pressure of 1 kPa to 70 kPa can be generated. After the water is sprayed out through the nozzle 132, it forms a cone-shaped water flow. The water flow is sprayed onto the mixing element 120 and bounces the mixing element 120 back to the bottom of the mixing chamber 113. As the mixing element 120 rotates, it drives the water flow to rotate, thereby rinsing the sidewalls of the mixing chamber 113. In addition, due to the high water pressure, the sprayed water flow can rinse the top wall of the mixing chamber 113, i.e., the inner wall of the lid 112 of the mixing cup 110, achieving a thorough cleaning of the mixing chamber 113 and the mixing element 120 without dead angles, thus improving the automatic cleaning effect of the food processor 100.

[0215] Due to the flow-limiting effect of nozzle 131, the generated conical water flow can form a cone angle between 45° and 160°, such as... Figure 1 The β angle ensures that the water flow thoroughly cleans the mixing chamber 113 and the mixing component 120, so that the food residue adhering to the mixing chamber 113 or the mixing component 120 is washed off, making the cleaning of the mixing chamber 113 more thorough.

[0216] In specific applications, nozzle 131 further includes a third sidewall and a fourth sidewall, which are located at nozzle 132 and are positioned opposite each other. The third sidewall is connected to the first and second sidewalls, and the fourth sidewall is connected to the first and second sidewalls, thereby forming an "I"-shaped nozzle 132 by the first, second, third, and fourth sidewalls. Specifically, the distance between the third and fourth sidewalls can be between 4mm and 12mm, thereby ensuring the spray area of ​​nozzle 132, improving the water intake efficiency of mixing chamber 113, and thus improving the preparation and cleaning efficiency of food processor 100, while ensuring the flow-limiting effect of nozzle 131, thereby ensuring the spray force of cleaning medium and improving the cleaning effect.

[0217] like Figure 3As shown, based on the above embodiment, the nozzle 131 further includes a third sidewall and a fourth sidewall located at the nozzle 132 and disposed opposite to each other. The third sidewall is connected to the first sidewall and the second sidewall, and the fourth sidewall is connected to the first sidewall and the second sidewall. The distance n between the third sidewall and the fourth sidewall satisfies 4mm≤n≤12mm.

[0218] In this embodiment, the nozzle 131 further includes a third sidewall and a fourth sidewall, which are located at the nozzle 132 and are arranged opposite to each other. The third sidewall is connected to the first and second sidewalls, and the fourth sidewall is connected to the first and second sidewalls, thereby forming an "I"-shaped nozzle 132 by the first, second, third, and fourth sidewalls. Specifically, the distance between the third and fourth sidewalls can be between 4mm and 12mm, thereby ensuring the spray area of ​​the nozzle 132, improving the water intake efficiency of the mixing chamber 113, and thus improving the preparation and cleaning efficiency of the food processor 100, while ensuring the flow-limiting effect of the nozzle 131, thereby ensuring the spray force of the cleaning medium and improving the cleaning effect.

[0219] It is understandable that if the distance between the third and fourth sidewalls is too large, although the spray area of ​​the nozzle 132 can be increased, the spray force of the cleaning medium will be reduced accordingly. If the distance between the third and fourth sidewalls is too small, although the spray force of the cleaning medium can be increased, the spray area of ​​the nozzle 132 will be reduced, thus prolonging the food preparation and automatic cleaning time.

[0220] Example 3:

[0221] like Figure 2 As shown, based on the above embodiment, the nozzle 131 further includes a body 1311 and a limiting part 1312, wherein the nozzle 132 is disposed on the body 1311, and the limiting part 1312 is connected to the end of the body 1311 away from the nozzle 132, and the limiting part 1312 can be limited and cooperated with the stirring cup 110.

[0222] In this embodiment, the nozzle 131 is further defined as including a body 1311 and a limiting part 1312. Specifically, the nozzle 132 is disposed on the body 1311, and the limiting part 1312 is connected to the end of the body 1311 away from the nozzle 132. The limiting part 1312 can be limited and cooperated with the mixing cup 110, thereby improving the installation stability of the nozzle 131 and thus improving the stability of the food processor 100 during food preparation and automatic cleaning.

[0223] It is understandable that, due to the flow-limiting effect of the nozzle 131, the cleaning medium sprayed through the nozzle 132 has a certain pressure. If the nozzle 131 has poor installation stability, when the cleaning medium is sprayed into the mixing chamber 113 through the nozzle 131, the nozzle 131 is prone to detach from the mixing cup 110, resulting in leakage of food or cleaning medium in the mixing chamber 113, which reduces the user experience.

[0224] By setting the limiting part 1312 to cooperate with the mixing cup 110, the installation stability and reliability of the nozzle 131 are improved, thereby ensuring the stable operation of the food processor 100.

[0225] In practical applications, the body 1311 and the limiting part 1312 are integrated into one structure, which can improve the connection strength between the body 1311 and the limiting part 1312 and further enhance the installation stability of the nozzle 131.

[0226] like Figure 2 As shown, based on the above embodiment, the food processor 100 further includes a limiting groove 140, which is disposed on the mixing cup 110 and located outside the mixing chamber 113. The first end of the limiting part 1312 is connected to the body 1311, and the second end of the limiting part 1312 is inserted into the limiting groove 140.

[0227] In this embodiment, the food processor 100 is further defined as including a limiting groove 140. Specifically, the limiting groove 140 is disposed on the mixing cup 110 and is located outside the mixing chamber 113. One end of the limiting part 1312 is connected to the body 1311, and the other end extends radially away from the nozzle 132, so that the other end of the limiting part 1312 is inserted into the limiting groove 140, thereby limiting and cooperating with the limiting groove 140, improving the installation stability of the nozzle 131, and thus improving the stability of the food processor 100 during food preparation and automatic cleaning.

[0228] It is understandable that, due to the flow-limiting effect of the nozzle 131, the cleaning medium sprayed through the nozzle 132 has a certain pressure. If the nozzle 131 has poor installation stability, when the cleaning medium is sprayed into the mixing chamber 113 through the nozzle 131, the nozzle 131 is prone to detach from the mixing cup 110, resulting in leakage of food or cleaning medium in the mixing chamber 113, which reduces the user experience.

[0229] By setting the limiting part 1312 to cooperate with the limiting groove 140, the installation stability and reliability of the nozzle 131 are improved, thereby ensuring the stable operation of the food processor 100.

[0230] Example 4:

[0231] like Figure 2As shown, based on the above embodiment, the nozzle 131 is further made of a flexible part; the food processor 100 also includes a mounting hole 150, which is connected to the limiting groove 140. One end of the body 1311 away from the limiting part 1312 extends into the mixing chamber 113 through the mounting hole 150, and the body 1311 abuts against the wall of the mounting hole 150.

[0232] In this embodiment, the food processor 100 further includes a mounting hole 150. Specifically, the mounting hole 150 communicates with the limiting groove 140, and one end of the main body 1311 facing away from the limiting part 1312 extends into the mixing chamber 113 through the mounting hole 150. That is, the mounting hole 150 communicates with the mixing chamber 113. The end of the main body 1311 facing away from the limiting part 1312 extending into the mixing chamber 113 means that the end of the main body 1311 with the nozzle 132 extends into the mixing chamber 113, facilitating the spraying of cleaning medium into the mixing chamber 113 through the nozzle 132. Specifically, the cleaning medium is sprayed upwards from the bottom of the mixing chamber 113, thereby enabling the cleaning of the mixing components 120, the side walls of the mixing chamber 113, the bottom wall of the mixing chamber 113, and the top wall of the mixing chamber 113, as well as other localized and hard-to-reach areas, improving the automatic cleaning effect of the food processor 100 and enhancing the user experience.

[0233] The nozzle 131 is a flexible component, and the body 1311 abuts against the wall of the mounting hole 150, thereby forming a seal between the wall of the mounting hole 150 and the body 1311, preventing food or cleaning medium in the mixing chamber 113 from leaking from the gap between the wall of the mounting hole 150 and the body 1311, thus improving the user experience.

[0234] In practical applications, the nozzle 131 is a silicone part, that is, the nozzle 131 has a certain elasticity, which can improve the sealing effect between the wall of the mounting hole 150 and the body 1311.

[0235] like Figure 2 As shown, based on the above embodiment, the body 1311 further includes a spray washing section 1311a and a sealing section 1311b, wherein the nozzle 132 is disposed in the spray washing section 1311a, the sealing section 1311b is located between the spray washing section 1311a and the limiting section 1312, and is connected to the spray washing section 1311a and the limiting section 1312, and the sealing section 1311b abuts against the wall of the mounting hole 150; the spray washing section 1311a includes a first end and a second end, the first end of the spray washing section 1311a is disposed closer to the nozzle 132 than the second end of the spray washing section 1311a, and along the height direction of the stirring cup 110, the thickness of the first end of the spray washing section 1311a is less than the thickness of the second end of the spray washing section 1311a.

[0236] In this embodiment, the body 1311 is defined as including a spray washing section 1311a and a sealing section 1311b. Specifically, the nozzle 132 is disposed in the spray washing section 1311a, and the sealing section 1311b is located between the spray washing section 1311a and the limiting section 1312. One end of the sealing section 1311b is connected to the limiting section 1312, and the other end is connected to the spray washing section 1311a. The sealing section 1311b abuts against the wall of the mounting hole 150. This forms a seal between the wall of the mounting hole 150 and the sealing section 1311b, preventing food or cleaning medium in the stirring chamber 113 from leaking through the gap between the wall of the mounting hole 150 and the sealing section 1311b, thus improving the user experience.

[0237] The spray washing section 1311a includes a first end and a second end facing away from each other. The first end of the spray washing section 1311a is positioned closer to the nozzle 132 than the second end, meaning the first end of the spray washing section 1311a is connected to the sealing section 1311b, and the other end is located at the nozzle 132. Specifically, along the height direction of the stirring cup 110, the thickness of the first end of the spray washing section 1311a is less than the thickness of the second end. In other words, the thickness of the end of the spray washing section 1311a closer to the sealing section 1311b is set to be thicker, and the thickness of the end of the spray washing section 1311a located at the nozzle 132 is set to be thinner, i.e., the thickness of the spray washing section 1311a is non-uniform.

[0238] By making the thickness of the end of the spray cleaning part 1311a near the sealing part 1311b thicker and the thickness of the end of the spray cleaning part 1311a located at the nozzle 132 thinner, while ensuring that the nozzle 132 effectively restricts the flow to generate reasonable water pressure, the problem of breakage caused by the repeated opening and closing of the spray cleaning part 131a during the spraying of cleaning medium is prevented, thus extending the service life of the nozzle 131.

[0239] In practical applications, the spraying part 1311a and the sealing part 1311b are integrated into one structure, which can improve the connection strength between the spraying part 1311a and the sealing part 1311b. Furthermore, it can prevent the spraying part 1311a from breaking due to repeated opening and closing when spraying the cleaning medium, thus extending the service life of the nozzle 131.

[0240] In one specific embodiment, the thickness d of the first end of the spray washing section 1311a further satisfies 0.5mm≤d≤3.5mm.

[0241] In this embodiment, the thickness of the first end of the spray washing section 1311a is between 0.5mm and 3.5mm along the height direction of the stirring cup 110. This ensures that the nozzle 132 can effectively limit the flow to generate reasonable water pressure, while also ensuring the structural strength of the first end of the spray washing section 1311a and extending the service life of the nozzle 131.

[0242] It is understandable that if the thickness of the first end of the spray section 1311a is too thin, an effective and reasonable water pressure cannot be generated at the nozzle 132, thereby reducing the spray force of the cleaning medium. If the thickness of the first end of the spray section 1311a is set to be thicker, although effective flow restriction can be achieved, the spray area at the nozzle 132 is smaller, which will reduce the efficiency of food preparation or cleaning of the mixing chamber 113.

[0243] By limiting the thickness of the first end of the spray section 1311a to between 0.5mm and 3.5mm, it is possible to ensure the effective flow restriction of the nozzle 132 to generate reasonable water pressure, while ensuring the structural strength of the first end of the spray section 1311a and extending the service life of the nozzle 131.

[0244] It is understandable that when the cleaning medium is sprayed into the mixing chamber 113, the first end of the spraying part 1311a will open into the mixing chamber 113 to increase the spraying area of ​​the nozzle 132 and ensure the efficiency of food preparation and cleaning of the mixing chamber 113.

[0245] In another specific embodiment, the included angle α between the side of the spray section 1311a facing the stirring chamber 113 and the side of the spray section 1311a away from the stirring chamber 113 satisfies 10°≤α≤45°.

[0246] In this embodiment, the side of the spray section 1311a facing the mixing chamber 113 and the side of the spray section 1311a facing away from the mixing chamber 113 form an angle between 10° and 45°. That is, at least one of the sides of the spray section 1311a facing the mixing chamber 113 and the side facing away from the mixing chamber 113 is an inclined surface. It is understood that the end of the spray section 1311a near the sealing part 1311b is thicker, and the end near the nozzle 132 is thinner. Therefore, if the side of the spray section 1311a facing away from the mixing chamber 113 is an inclined surface, this inclined surface is inclined upwards from the second end to the first end of the spray section 1311a. If the side of the spray section 1311a facing the mixing chamber 113 is an inclined surface, this inclined surface is inclined downwards from the second end to the first end of the spray section 1311a. This results in a uniform change in the structure of the spray section 1311a, where the thickness of the spray section 1311a gradually decreases from the second end to the first end. This ensures that the nozzle 132 effectively limits the flow to generate reasonable water pressure, while preventing the spray section 1311a from breaking due to repeated opening and closing during the spraying of the cleaning medium, thus extending the service life of the nozzle 131.

[0247] Example 5:

[0248] like Figure 1 and Figure 2 As shown, based on the above embodiment, the food processor 100 further includes a mounting connector 160 and a water inlet pipe 170. The mounting connector 160 is located on the side of the nozzle 131 away from the mixing chamber 113, and the water inlet pipe 170 is connected to the mounting connector 160 and can communicate with the nozzle 132.

[0249] In this embodiment, the food processor 100 further includes a mounting connector 160 and a water inlet pipe 170. Specifically, the mounting connector 160 is located on the side of the nozzle 131 facing away from the mixing chamber 113, and the water inlet pipe 170 is connected to the mounting connector 160 and can communicate with the nozzle 132. By providing the mounting connector 160, the water inlet pipe 170 can be installed, thereby supplying water to the nozzle 132 through the water inlet pipe 170, and then spraying cleaning medium into the mixing chamber 113 through the nozzle 132. This allows for spray cleaning of local areas and dead corners such as the mixing component 120, the side wall of the mixing chamber 113, the bottom wall of the mixing chamber 113, and the top wall of the mixing chamber 113, improving the automatic cleaning effect of the food processor 100 and thus enhancing the user experience of the food processor 100.

[0250] It is understandable that one end of the water inlet pipe 170 can be connected to the nozzle 132, and the other end can be connected to a water source. Specifically, a water tank 210 can be installed on the blender 100, meaning the other end of the water inlet pipe 170 is connected to the water tank 210 via the water pump assembly 220, thus improving the fully automatic and intelligent level of the blender 100. Alternatively, the other end of the water inlet pipe 170 can be connected to an external water source, thereby simplifying the structure of the blender 100 and reducing its production cost. The specific configuration can be determined according to actual needs.

[0251] like Figure 1 and Figure 2 As shown, based on the above embodiment, the food processor 100 further includes a switch valve 180, which is disposed on the water inlet pipe 170 and is used to control the opening and closing of the water inlet pipe 170.

[0252] In this embodiment, the food processor 100 is further defined as including a switch valve 180. Specifically, the switch valve 180 is disposed on the water inlet pipe 170, and the switch valve 180 can control the opening and closing of the water inlet pipe 170. That is, the switch valve 180 can control whether water is sprayed into the mixing chamber 113 through the water inlet pipe 170 and the nozzle 132, thereby facilitating the control of the working process of the food processor 100 and improving the user experience.

[0253] In addition, when the food processor 100 crushes and blends the ingredients in the mixing chamber 113, the switch valve 180 is closed, which can prevent the water in the mixing chamber 113 from flowing back and ensure the effective preparation of the ingredients.

[0254] It is understandable that since the nozzle 132 is a straight nozzle 131, that is, the distance between the first sidewall and the sidewall is small, it can prevent the food in the mixing chamber 113 from leaking out from the nozzle 132.

[0255] In practical applications, the switch valve 180 is a one-way valve. The one-way valve conducts in a unidirectional direction from the water inlet pipe 170 to the nozzle 132, which simplifies the control process of the food processor 100 and improves the user experience.

[0256] like Figure 1 As shown, based on the above embodiment, the food processor 100 further includes a water tank 210 and a water pumping assembly 220, wherein the water pumping assembly 220 is connected to the water inlet pipe 170 and the water tank 210.

[0257] In this embodiment, the food processor 100 is further defined as including a water tank 210 and a water pumping assembly 220. Specifically, one end of the water pumping assembly 220 is connected to the water inlet pipe 170, and the other end of the water pumping assembly 220 is connected to the water tank 210.

[0258] Since the water inlet pipe 170 is connected to the mixing chamber 113 through the nozzle 132, when the water pumping component 220 is working, the water in the water tank 210 can be pumped into the mixing chamber 113 through the water inlet pipe 170, so as to realize the food preparation of the food processor 100 and the cleaning of the mixing chamber 113.

[0259] By equipping the food processor 100 with a water tank 210, it is convenient to introduce water from the water tank 210 into the mixing chamber 113, thereby improving the ease of use of the food processor 100 and enhancing its fully automatic and intelligent level.

[0260] In practical applications, the water pumping assembly 220 includes a water pump and a water pumping pipe. A water outlet is provided at the bottom of the water tank 210. One end of the water pumping pipe is connected to the water pump, and the other end is connected to the water outlet. Thus, when the water pump is working, the water in the water tank 210 can be pumped through the water outlet, the water pumping pipe, and the water inlet pipe 170 to the stirring chamber 113 to realize the preparation of food or the cleaning of the stirring chamber 113.

[0261] Example 6:

[0262] like Figure 1 As shown, based on the above embodiment, the stirring cup 110 further includes a cup body 111 and a lid 112, wherein the lid 112 covers the top of the cup body 111 and surrounds the cup body 111 to form a stirring chamber 113.

[0263] In this embodiment, the mixing cup 110 is defined as including a cup body 111 and a lid 112. Specifically, the lid 112 is placed on the top of the cup body 111. It is understood that the top of the cup body 111 has an open end, and the lid 112 is placed on the open end of the top of the cup body 111. Specifically, the lid 112 is closable and can be placed on the open end of the top of the cup body 111, so that the user can place the ingredients to be prepared by opening the lid 112.

[0264] The lid 112 and the cup 111 enclose a mixing chamber 113. In other words, the inner wall of the lid 112 is the top wall of the mixing chamber 113. Since the spray cleaning device 130 is located at the bottom of the mixing cup 110, when the spray cleaning device 130 sprays cleaning medium into the mixing chamber 113, the cleaning medium is sprayed upward from the bottom of the mixing chamber 113. This allows for the spray cleaning of the mixing components 120, the side walls of the mixing chamber 113, the bottom wall of the mixing chamber 113, and the inner wall of the lid 112, as well as other local and hard-to-reach areas. This improves the automatic cleaning effect of the food processor 100 and enhances the user's experience with the food processor 100.

[0265] Example 7:

[0266] like Figure 1 and Figure 3 As shown, based on the above embodiment, the rotational speed R of the stirring component 120 further satisfies 0 r / min ≤ R ≤ 1000 r / min.

[0267] In this embodiment, the rotational speed R of the stirring element 120 is limited to between 0 r / min and 1000 r / min. When the automatic cleaning function of the food processor 100 is activated, the stirring element 120 can be driven to rotate by the drive element, and the rotational speed of the stirring element 120 can be between 0 r / min and 1000 r / min. The rotation of the stirring element 120 drives the cleaning medium to rotate, thereby impacting and cleaning the stirring chamber 113, thus improving the cleaning effect of the food processor 100.

[0268] In detail, when the cleaning medium is sprayed into the mixing chamber 113 by the spraying device 130, the agitator 120 can rotate within the mixing chamber 113. When the blades of the agitator 120 pass through the sprayed cleaning medium, the agitator 120 can be cleaned. Moreover, when the agitator 120 encounters the cleaning medium, it will bounce the cleaning medium against the bottom wall of the mixing chamber 113, thereby cleaning the bottom wall of the mixing chamber 113 and the local areas and dead corners in contact with the bottom wall of the mixing chamber 113. In addition, when the cleaning medium passes through the gap between two adjacent blades of the agitator 120, the agitator 120 will drive the cleaning medium to rotate, thereby flushing the side walls and top wall of the mixing chamber 113, thus achieving a comprehensive and thorough cleaning of the mixing chamber 113.

[0269] In practical applications, when the food processor 100 prepares ingredients in the mixing chamber 113, the rotation speed of the mixing element 120 can be increased to achieve rapid preparation of the ingredients. The specific rotation speed can be set according to actual needs.

[0270] Example 8:

[0271] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, based on the above embodiment, the mixing cup 110 further includes a dispensing port 114, which is connected to the mixing chamber 113; the food processor 100 also includes a heating element 230, a first cup holder 240, and a second cup holder 250. The heating element 230 is disposed on the side of the mixing cup 110 away from the dispensing port 114, and the mixing chamber 113 is formed between the heating element 230 and the mixing cup 110. The first cup holder 240 is disposed on the side of the heating element 230 away from the mixing chamber 113, and the second cup holder 250 is disposed on the side of the mixing cup 110 away from the mixing chamber 113. The second cup holder 250 is connected to the first cup holder 240, and a portion of the mixing cup 110 and a portion of the heating element 230 are sandwiched between the first cup holder 240 and the second cup holder 250.

[0272] In this embodiment, the food processor 100 is further defined as including a heating element 230, a first cup holder 240 and a second cup holder 250. Specifically, the blending cup 110 has a pick-up and drop-out port 114, which is connected to the blending chamber 113, allowing the user to pick up the food in the blending chamber 113 through the pick-up and drop-out port 114.

[0273] The heating element 230 is located on the side of the mixing cup 110 away from the dispensing port 114. A mixing chamber 113 is formed between the heating element 230 and the mixing cup 110. That is, the heating element 230 and the mixing cup 110 together form the mixing chamber 113. When food is located in the mixing chamber 113, it can directly contact the heating element 230, thereby improving heating efficiency. When the dispensing port 114 of the mixing cup 110 is facing upwards, the heating element 230 is located at the bottom of the mixing cup 110. The heating element 230 can be directly connected to the mixing cup 110, or it can be indirectly connected to the mixing cup 110, thereby forming the mixing chamber 113.

[0274] The first cup holder 240 is located on the side of the heating element 230 away from the stirring chamber 113, that is, the first cup holder 240 is located on the outside of the heating element 230, and the inside of the heating element 230 is used to form the stirring chamber 113 together with the stirring cup 110.

[0275] The second cup holder 250 is located on the side of the stirring cup 110 away from the stirring chamber 113, that is, the second cup holder 250 surrounds the outside of the stirring cup 110. Along the depth direction of the stirring cup 110, such as the vertical direction, the second cup holder 250 and the first cup holder 240 can be reliably connected, so that the first cup holder 240 and the second cup holder 250 form a rigid whole. While the first cup holder 240 and the second cup holder 250 are locked together, a part of the heating element 230 and a part of the stirring cup 110 respectively abut against the first cup holder 240 and the second cup holder 250. For example, when the first cup holder 240 is positioned lower than the second cup holder 250, the first cup holder 240 can provide an upward supporting force to the heating element 230, and the second cup holder 250 can apply downward pressure to the stirring cup 110. Under the combined action of the supporting force provided by the first cup holder 240 and the pressure applied by the second cup holder 250, the heating element 230 and the stirring cup 110 are clamped and fixed between the first cup holder 240 and the second cup holder 250.

[0276] The heating element 230 and the stirring cup 110 are fixed by the first cup holder 240 and the second cup holder 250, so that the stirring cup 110 and the heating element 230 form a whole. The structure is simple and the assembly is ingenious, which can effectively reduce the difficulty of production and improve production efficiency.

[0277] Based on the above embodiments, the first cup holder 240 and the second cup holder 250 are further detachably connected by a locking connector.

[0278] In this embodiment, the first cup holder 240 and the second cup holder 250 are detachably connected by a locking connector. When the locking connector is removed from the first cup holder 240 and the second cup holder 250, the first cup holder 240, the second cup holder 250, the heating element 230 and the mixing cup 110 are directly separable components. No other fastening connection is required between the components, which facilitates the disassembly and maintenance of the food processor 100.

[0279] like Figure 6 and Figure 9 As shown, based on the above embodiment, the food processor 100 further includes a first flexible part 260 and a second flexible part 270, wherein the first flexible part 260 is disposed between the mixing cup 110 and the heating element 230, and the second flexible part 270 is disposed between the first cup base 240 and the heating element 230.

[0280] In this embodiment, the food processor 100 is further defined as including a first flexible part 260 and a second flexible part 270. Specifically, when the mixing element 120 rotates at high speed, the mixing cup 110 will vibrate. Since the first flexible part 260 is provided between the mixing cup 110 and the heating element 230, the first flexible part 260 realizes a soft connection between the heating element 230 and the mixing cup 110, thereby slowing down the transmission of vibration generated at the mixing cup 110 to the heating element 230 side, reducing vibration transmission, and reducing the vibration of the entire food processor 100.

[0281] At the same time, it can also extend the service life of the heating element 230, avoid problems such as poor contact of the heating element 230 caused by vibration transmitted to the heating element 230, and ensure the safe use performance of the heating element 230.

[0282] Furthermore, a second flexible part 270 is provided between the first cup holder 240 and the heating element 230, thereby realizing a soft connection between the first cup holder 240 and the heating element 230. This can further reduce the transmission of vibration generated at the mixing cup 110 to the heating element 230 and the first cup holder 240, weaken vibration transmission, and reduce the vibration of the entire food processor 100.

[0283] Optionally, the heating element 230 includes a heating plate located at the bottom of the stirring cup 110.

[0284] like Figure 6 As shown, based on the above embodiment, a portion of the stirring cup 110 extends radially in a direction away from the central axis of the stirring cup 110 to form a first limiting portion 115, and a portion of the heating element 230 extends radially in a direction away from the central axis to form a second limiting portion 231; wherein, a portion of the second cup seat 250 is disposed on the end face of the first limiting portion 115 away from the second limiting portion 231, and a portion of the first cup seat 240 is disposed on the end face of the second limiting portion 231 away from the first limiting portion 115, so as to clamp and fix the stirring cup 110 and the heating element 230.

[0285] In this embodiment, a portion of the stirring cup 110 extends radially in a direction away from the central axis of the stirring cup 110 to form a first limiting portion 115, that is, a portion of the stirring cup 110 extends radially outward to form a first limiting portion 115. The first limiting portion 115 includes an end face away from the second limiting portion 231, that is, the upper end face of the first limiting portion 115.

[0286] A portion of the heating element 230 extends radially in a direction away from the central axis to form a second limiting portion 231, that is, a portion of the heating element 230 extends radially outward to form a second limiting portion 231. The second limiting portion 231 includes an end face away from the first limiting portion 115, that is, the lower end face of the second limiting portion 231.

[0287] The second cup holder 250 applies a downward force to the stirring cup 110 through the upper end of the first limiting part 115, and the first cup holder 240 provides an upward supporting force to the heating element 230 through the lower end of the second limiting part 231. Under the combined action of the downward force provided by the second cup holder 250 and the upward supporting force provided by the first cup holder 240, the stirring cup 110 and the heating element 230 are reliably clamped between the first cup holder 240 and the second cup holder 250.

[0288] Optionally, the first limiting part 115 is an annular limiting frustum.

[0289] Optionally, the second limiting part 231 is an annular limiting frustum.

[0290] like Figure 6 As shown, based on the above embodiment, a portion of the second cup holder 250 extends axially in the direction close to the heating element 230 to form a third limiting portion 251. The third limiting portion 251 is located on the radial side of the first limiting portion 115 to restrict the radial movement of the stirring cup 110.

[0291] In this embodiment, a portion of the second cup holder 250 extends axially in the direction close to the heating element 230 to form a third limiting portion 251. That is, a portion of the second cup holder 250 extends downward to form the third limiting portion 251. The third limiting portion 251 is located on the radial side of the first limiting portion 115, that is, the third limiting portion 251 is located on the outside of the stirring cup 110. The third limiting portion 251 can contact the first limiting portion 115, thereby restricting the radial movement of the stirring cup 110. The first cup holder 240 and the second cup holder 250 not only provide axial positional restriction for the stirring cup 110, but also ensure the radial positional stability of the stirring cup 110.

[0292] like Figure 6 As shown, based on the above embodiment, the first cup holder 240 further includes a support portion 241 and a fourth limiting portion 242, wherein the second limiting portion 231 overlaps the support portion 241, the fourth limiting portion 242 is connected to the support portion 241 and extends axially in a direction close to the first limiting portion 115, and the fourth limiting portion 242 is located on the radial side of the second limiting portion 231 to restrict the radial movement of the heating element 230.

[0293] In this embodiment, the first cup holder 240 includes a support portion 241 and a fourth limiting portion 242. The second limiting portion 231 overlaps the support portion 241, that is, the support portion 241 is used to provide axial support force to the heating element 230. The fourth limiting portion 242 is connected to the support portion 241 and extends axially in a direction close to the first limiting portion 115, that is, the fourth limiting portion 242 extends upward. The fourth limiting portion 242 is located on the radial side of the second limiting portion 231. The fourth limiting portion 242 can contact the second limiting portion 231 of the heating element 230, thereby restricting the radial movement of the heating element 230.

[0294] In other words, in the axial direction, the first cup holder 240 and the second cup holder 250 can clamp the heating element 230 and the stirring cup 110, and in the radial direction, the third limiting part 251 and the fourth limiting part 242 can restrict the movement of the stirring cup 110 and the heating element 230, thereby ensuring the positional stability of the heating element 230 and the stirring cup 110.

[0295] like Figure 4 and Figure 5 As shown, based on the above embodiment, the second flexible part 270 is further installed on the heating element 230 and then assembled in the first cup holder 240. The second cup holder 250 is connected to the first cup holder 240 through a locking connector. There is a receiving cavity between the first cup holder 240, the second cup holder 250 and the heating element 230. The first flexible part 260 is located in the receiving cavity and is disposed on the heating element 230. The stirring cup 110 extends into the receiving cavity and contacts the second cup holder 250 and the first flexible part 260 respectively to form a cup assembly. The food processor 100 also includes a housing 190 and a vibration damping connector 280. The housing 190 is provided with a mounting cavity 191. The cup assembly extends into the mounting cavity 191 and is connected to the housing 190 through the vibration damping connector 280.

[0296] In this embodiment, during the assembly process of the food processor 100, the second flexible part 270 can be installed on the heating element 230. Specifically, the second flexible part 270 includes a bottom rubber seat and a side gasket. The bottom rubber seat is installed on the bottom of the heating element 230, and the side gasket is installed on the side of the heating element 230, that is, the side gasket is installed on the second limiting part 231 of the heating element 230.

[0297] Then, the heating element 230 with the second flexible part 270 is installed inside the first cup holder 240. It is conceivable that the first cup holder 240 has an installation space inside in order to meet the installation requirements of the heating element 230.

[0298] Next, the second cup holder 250 is installed on the first cup holder 240 through the locking connector. At this time, the first cup holder 240 and the second cup holder 250 are fixed into a rigid body, and the rigid body has a receiving cavity inside.

[0299] Then, the first flexible part 260 is placed inside the receiving cavity. The first flexible part 260 is disposed on the heating element 230. Next, the mixing cup 110 is screwed into the second cup holder 250 for fixation. At the same time, the first flexible part 260 is also clamped by the mixing cup 110 and the heating element 230, which not only seals the gap between the mixing cup 110 and the heating element 230, but also enables the two to achieve a flexible connection, further improving the vibration reduction performance of the entire food processor 100. It is worth noting that the first cup holder 240, the second cup holder 250, the heating element 230, the mixing cup 110, the first flexible part 260, and the second flexible part 270 are fixed into a whole, namely the cup body assembly.

[0300] During the assembly of the cup body assembly and the housing 190, the cup body assembly can be inserted into the housing 190 from below, and then the cup body assembly and the housing 190 can be fixed together by the vibration damping connector 280.

[0301] A vibration damping connector 280 is provided between the housing 190 and the cup assembly. The vibration damping connector 280 allows the cup assembly to be suspended in the mounting cavity 191. That is, the cup assembly and the housing 190 are only connected by the vibration damping connector 280, without any other rigid connection structure. Therefore, when the food processor 100 is working, the vibration damping connector 280 can effectively reduce the vibration and noise of the cup assembly. The vibration damping connector 280 relies on its own vibration damping performance to buffer the vibration and noise generated by the cup assembly, which significantly improves the vibration and noise generated by the entire food processor 100.

[0302] Example 9:

[0303] like Figure 10 As shown, according to an embodiment of the second aspect of the present invention, a control method for a food processor is proposed. The food processor includes a mixing chamber, a discharge port, and a discharge valve. The discharge port is connected to the mixing chamber, and the discharge valve can control the opening and closing of the discharge port. The control method includes:

[0304] Step 102: Control the discharge valve to close the discharge port. With the discharge valve closed, control the water pumping component of the food processor to inject the first preset amount of liquid into the mixing chamber and complete the pulping process.

[0305] Step 104: Control the discharge valve to open the discharge port, and with the discharge valve open, control the discharge port to connect with the receiving cup.

[0306] Step 106: After the slurry is discharged, control the discharge valve to close the discharge port. With the discharge valve closed, control the water pumping component to inject the second preset amount of liquid into the mixing chamber, and control the mixing component of the food processor to rotate at a preset speed to clean the mixing chamber at least once.

[0307] Step 108: After cleaning, control the discharge valve to open the discharge port. With the discharge valve open, control the discharge port to connect with the waste receiving cup.

[0308] The food processor provided in this embodiment of the invention includes a mixing chamber, a discharge port, and a discharge valve. Specifically, the mixing cup of the food processor has a mixing chamber, the discharge port is connected to the mixing chamber, and the discharge valve is disposed on the mixing cup and located at the discharge port to control the opening and closing state of the discharge port. It is understood that the food processor also includes a water tank and a water pumping assembly. The water tank is connected to the mixing chamber through the water pumping assembly, that is, water is supplied from the water tank to the mixing chamber through the water pumping assembly.

[0309] Before pulping, the discharge valve is closed and the discharge port is turned on. The water pumping unit is started to send the water in the water tank to the mixing chamber. Understandably, the mixing components of the food processor rotate at high speed under the drive of the food processor to beat the ingredients in the mixing chamber at high speed to make pulp.

[0310] After the pulping process is complete, the discharge valve opens the discharge port, and the pulp is collected in the receiving cup. It's understood that the food processor can include a receiving cup, or it can be a regular household cup. The specific configuration can be adjusted according to actual needs.

[0311] After the slurry is collected, close the discharge port by controlling the discharge valve and start cleaning the mixing chamber at least once.

[0312] Each time the machine is cleaned, the pumping unit is controlled to inject water into the mixing chamber, and the mixing components are controlled to rotate at a preset speed. During the rotation of the mixing components, water is sprayed and rotated in the mixing chamber, thereby spraying and cleaning the mixing components, the side walls, bottom walls, and top walls of the mixing chamber, improving the automatic cleaning effect of the food processor and enhancing the user experience.

[0313] After each cleaning cycle, control the discharge valve to open the discharge port and drain the wastewater from the mixing chamber into the waste collection cup. It's understood that the food processor may include a waste collection cup, which can also be a regular household cup. The specific settings can be configured according to actual needs.

[0314] It is understandable that the food processor includes a serving cup and a waste cup, with the serving cup located on top of the waste cup. Once the food is collected, the cleaning process can be initiated, improving the fully automatic and intelligent level of the food processor and thus enhancing the user experience.

[0315] The cleaning process should be repeated at least 2 to 4 times to further improve the cleaning effect of the mixing chamber.

[0316] It should be noted that during the pulping process, a first preset amount of liquid is injected into the mixing chamber. This first preset amount can be set according to the user's desired pulping concentration or different types of ingredients.

[0317] The second preset amount is the injection volume when cleaning the mixing chamber. It is set according to the size of the mixing chamber, etc. It is understood that the second preset amount and the first preset amount can be the same or different.

[0318] Based on the above embodiments, further, the pumping component is controlled to inject a second preset amount of liquid into the mixing chamber, and the mixing component of the food processor is controlled to rotate at a preset speed. Specifically, this includes controlling the mixing component to rotate at a preset speed within a first preset time period after the pumping component starts injecting liquid into the mixing chamber.

[0319] In this embodiment, when the water pumping component injects liquid into the mixing chamber to clean it, the mixing element is controlled to rotate at a preset speed within a first preset time period after the water pumping component starts injecting liquid into the mixing chamber. That is, the timing starts when the liquid is injected into the mixing chamber, and the mixing element is controlled to rotate within the first preset time period. This allows the mixing chamber to be cleaned quickly while the liquid is flushed and cleaned by the rotation of the mixing element, thus shortening the cleaning time of the mixing chamber and improving the user's experience of using the food processor.

[0320] In practical applications, the first preset time is less than or equal to 10 seconds, and further, the first preset time is less than or equal to 5 seconds, so as to start the stirring component to rotate as quickly as possible when injecting liquid into the stirring chamber, thereby improving the cleaning effect of the stirring chamber.

[0321] Based on the above embodiments, the first preset duration t further satisfies t≤10s.

[0322] In this embodiment, the first preset time is limited to less than or equal to 10 seconds. It is understood that if the first preset time is longer, that is, more than 10 seconds after the water pumping component starts and injects liquid into the mixing chamber before controlling the mixing element to rotate, then the mixing chamber will already contain a certain amount of liquid, and the liquid level may even be higher than the mixing blades. This increases the driving force of the food processor's drive unit to drive the mixing element and reduces the impact force of the mixing element rotating and scouring the liquid, thus reducing the cleaning effect.

[0323] By controlling the rotation of the agitator within 10 seconds of injecting liquid into the mixing chamber, the rotation of the agitator can be started as quickly as possible when the liquid is injected into the mixing chamber, ensuring the impact force of the liquid rotation driven by the agitator to improve the cleaning effect of the mixing chamber.

[0324] Based on the above embodiments, the first preset duration t further satisfies t≤5s.

[0325] In this embodiment, the first preset duration is limited to less than or equal to 5 seconds. This can further shorten the start-up time of the agitator, that is, to start the agitator to rotate as quickly as possible when liquid is injected into the agitation chamber, ensuring the impact force of the agitator driving the liquid to rotate and flush, thereby improving the cleaning effect of the agitation chamber.

[0326] Based on any of the above embodiments, the preset rotational speed R further satisfies 0 r / min ≤ R ≤ 1000 r / min.

[0327] In this embodiment, the preset rotation speed R of the stirring element is limited to between 0 r / min and 1000 r / min. When the automatic cleaning function of the food processor is activated, the stirring element can be driven to rotate by the drive element, and the rotation speed of the stirring element can be between 0 r / min and 1000 r / min. The rotation of the stirring element drives the liquid injected into the mixing chamber to rotate, thereby impacting and cleaning the mixing chamber and improving the cleaning effect of the food processor.

[0328] In practical applications, when a food processor is preparing ingredients in the mixing chamber—that is, when the food processor is making a puree—the rotation speed of the mixing components can be increased to achieve rapid preparation of the ingredients. The specific rotation speed can be set according to actual needs.

[0329] Based on any of the above embodiments, the food processor further includes a spray washing device located at the bottom of the mixing chamber, which controls the water pumping component to inject a second preset amount of liquid into the mixing chamber. Specifically, it controls the water pumping component to spray the second preset amount of liquid into the mixing chamber through the spray washing device.

[0330] In this embodiment, the food processor also includes a spray cleaning device, which is located at the bottom of the mixing chamber. When the water pumping assembly injects liquid into the mixing chamber to clean it, the spray cleaning device sprays liquid into the mixing chamber. It is understood that because the spray cleaning device is located at the bottom of the mixing chamber, when it sprays liquid into the mixing chamber, the liquid is sprayed upwards from the bottom of the mixing chamber. This allows for thorough cleaning of the mixing components, the side walls, bottom wall, and top wall of the mixing chamber, as well as other hard-to-reach areas, improving the automatic cleaning effect of the food processor and thus enhancing the user experience.

[0331] It is worth noting that the spraying device is located within the projection of the plane of rotation formed when the agitator rotates, so that when the spraying device sprays liquid into the agitator chamber, the liquid can come into contact with the agitator.

[0332] In detail, when liquid is sprayed into the mixing chamber through the spraying device, the agitator rotates within the chamber. As the agitator blades pass through the sprayed liquid, they are cleaned. Furthermore, upon encountering the liquid, the agitator deflects it against the bottom wall of the mixing chamber, thus cleaning the bottom wall and the areas in contact with it, including hard-to-reach spots. Additionally, when the liquid passes through the gap between adjacent agitator blades, the agitator rotates the liquid, flushing the side and top walls of the mixing chamber, achieving a thorough and comprehensive cleaning.
