Description

Technical Field

[0001] This utility model relates to the field of household motor technology, and in particular to a food processor. Background Technology

[0002] To facilitate processing, most food processors use a cylindrical or open-topped mixing jar. The side walls of these jars are perpendicular to the bottom of the jar or form an obtuse angle with the surface. This means that the tumbling of food within the jar relies entirely on the blades, with the jar only serving to hold the food, resulting in low tumbling efficiency. Some products incorporate ribs on the inner wall of the mixing jar to aid in tumbling. However, these ribs increase the gap between the blades and the jar wall, creating blind spots for the blades. Furthermore, compared to the raised structure of the jar wall, the ribs make cleaning the mixing jar more difficult.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] A further technical solution is that the bottom wall and the side wall form a rounded corner segment through an arc transition.

[0007] A further technical solution is that, along the direction perpendicular to the bottom wall, the height of the rounded corner segment accounts for 30% of the height of the cup body.

[0023] Figure 1 A vertical cross-sectional view of a food processor according to an embodiment of this disclosure is shown. Please refer to... Figure 1The food processor includes a cup body 1 and a blending mechanism 4. The cup body 1 includes a bottom wall 11 and a side wall 12 surrounding the bottom wall 11. A cup opening 13 is formed on the side of the side wall 12 away from the bottom wall 11. A cavity 14 is formed between the side wall 12 and the bottom wall 11 to hold food, which enters the cavity 14 through the cup opening 13. The blending mechanism 4 extends into the cavity 14 through the cup opening 13 to blend the food within the cavity 14. A reflux section 121 is provided on the side wall 12 in a direction perpendicular to the bottom wall 11. Within the reflux section 121, an angle of 80°-88° is formed between the side wall 12 and the bottom wall 11, and the cross-section of the cavity 14 gradually narrows towards the cup opening 13. Preferably, the angle between the side wall 12 and the bottom wall 11 is 87°. When blending food, in addition to holding the food, the upward-moving food in the cup body 1 moves towards the blending center along the reflux section 121. When used in conjunction with the rotating and mixing mechanism, the centrifugal force generated by the clamping plate pushes the ingredients, causing them to rotate and tumble within the cup wall. This effectively improves the tumbling efficiency, resulting in more even mixing and better results. Furthermore, the tapered design of the cup body 1 makes its vertical cross-section nearly triangular, enhancing its stability and reducing vibration and noise.

[0024] In some embodiments, the sidewall 12 of the reflux section 121 can be arc-shaped, with its vertical cross-section being an arc protruding outward from the cup body 1. From bottom to top, the included angle between the reflux section 121 and the bottom wall 11 can gradually increase.

[0025] Taking an angle of 87° between side wall 12 and bottom wall 11 as an example, the following table shows the weight of different types of ingredients remaining after passing through sieves of different mesh sizes in the same amount of time for a blender with a straight-sided mixing cup (commercially available QSJ-W05G3 model) and a blender of the same model with the cup body replaced: 350g of chives QSJ-W05G3 20.2 54.9 226.9 123.1 Reverse slope handboard 3 degrees 0.6 16.2 144 206 3-degree improvement rate 97% 70% 37% 67% 500g celery QSJ-W05G3 56.3 245.3 374.9 125.1 Reverse slope handboard 3 degrees 0.5 7.4 207.4 292.6 Improvement rate 99% 97% 45% 134% 300g Chinese cabbage QSJ-W05G3 45.1 144.4 230.5 69.5 Reverse slope handboard 3 degrees 1.5 25.2 131.7 168.3 Improvement rate 97% 83% 43% 142% 500g carrots QSJ-W05G3 5 87 332.8 167.2 Reverse slope handboard 3 degrees 0 2.8 104.2 395.8 Improvement rate 100% 97% 69% 137% 500g garlic QSJ-W05G3 8.1 187.1 430.9 69.1 Reverse slope handboard 3 degrees 0 2.8 104.2 395.8 Improvement rate 100% 99% 76% 473% 500g of small red chilies QSJ-W05G3 10 131.4 366.6 133.4 Reverse slope handboard 3 degrees 3 81.5 214.3 285.7 Improvement rate 70% 38% 42% 114% As can be seen from the table above, regardless of the type of ingredient, compared to a regular cylindrical blender 1, a blender with an 87° angle between the side wall 12 and the bottom wall 11 can blend ingredients into finer and more uniform particles within the same blending time, significantly improving the blending efficiency of the blender.

[0026] Figure 2 A partial cross-sectional view of the cup portion of a food processor according to an embodiment of this disclosure is shown. Please refer to... Figure 1 and Figure 2 The stirring mechanism 4 includes a blade shaft 41 and a lower blade assembly 43 mounted on the blade shaft 41. The blade shaft 41 is positioned perpendicular to the bottom wall 11. Rotation of the blade shaft 41 causes the blades in the lower blade assembly 43 to rotate around the blade shaft 41, thus agitating the food in the container 14. A gap of 2-5 mm, preferably 3 mm, is provided between the lower blade assembly 43 and the bottom wall 11. This prevents interference between the blades in the lower blade assembly 43 and the bottom wall 11 during rotation. Simultaneously, limiting the gap to less than 5 mm prevents the creation of dead zones in the stirring process, ensuring the blades can reach the food at the bottom of the container 1.

[0027] Preferably, the lower blade assembly 43 includes a first blade 431 and a second blade 433 arranged around the blade shaft 41. In some embodiments, the first blade 431 and the second blade 433 are symmetrically arranged on the blade shaft 41 at an angle of 180°, so that the weight of the first blade 431 and the second blade 433, the centrifugal force generated during rotation, and the resistance are symmetrically applied to the blade shaft 41, enhancing the stability of the blade shaft 41. A gap of 10-15mm is provided between the first blade 431 and the second blade 433 along the axis of the blade shaft 41. This avoids the gap being too small, preventing large particles of food from entering and being mixed. A gap of more than 10mm allows most of the food to enter after processing begins, increasing the effective working space of the mixing mechanism 4 and improving the food processing efficiency. At the same time, a gap of less than 15mm between the first blade 431 and the second blade 433 is sufficient to chop the food into sufficiently small pieces, ensuring the processing effect.

[0028] In this design, the end of the first blade 431 furthest from the blade shaft 41 is bent towards the cup opening 13, forming a bent portion 432. The bent portion 432 allows the first blade 431 to fit more closely to the rounded corner section 15, reducing the gap between them and allowing the first blade 431 to better pick up and mix the food at the rounded corner section 15. Furthermore, when the first blade 431 with the upward-curving bent portion 432 rotates, centrifugal force drives the food to move along the surface of the blade 431. During this process, the bent portion 432 guides the food upwards to tumble it, improving the mixing effect. Preferably, the angle between the bent portion 432 and the axis of the blade shaft 41 is set between 18° and 23°. The upward angle of the bent portion 432 is limited to below 23° to prevent it from becoming too large. When the upward angle of the bend 432 is large, the food is driven by centrifugal force to move along the bend 432, and the bend 432 also applies resistance to the mixing of the food. The corresponding reaction force generated by the food is applied to the first blade 431 and the motor 31, reducing the service life of the mixing mechanism 4. Furthermore, when the bending angle of the bend 432 is too large, the gap between the first blade 431 and the rounded corner section 15 will also increase, making it easy for food to accumulate in dead corners.

[0029] Please refer to Figure 1 and Figure 2 The bottom wall 11 and the side wall 12 are connected by an arc to form a rounded corner segment 15. The rounded corner segment 15 prevents the bottom wall 11 and the side wall 12 from forming a right-angle dead angle that could trap food.

[0030] Preferably, the height of the rounded corner section 15, perpendicular to the bottom wall 11, is 30% of the height of the cup body 1. If the height of the rounded corner section 15 is set too high, the ingredients lifted by the lower blade assembly 43 will not reach the return section 121 even after moving a long distance upwards, resulting in low efficiency in the return of ingredients to the mixing range. If the height of the rounded corner section 15 is set too low, the ingredients will contact the return section 121 after moving only a short distance upwards. Under the reaction force of the return section 121, they will be pushed towards the blade shaft 41 and hindered from moving upwards. The tumbling distance of the ingredients will be short, resulting in insufficient and uneven mixing, which will affect the mixing effect.

[0031] More preferably, an upper blade assembly 42 is also provided on the blade shaft 41. The upper blade assembly 42 is located on the side of the lower blade assembly 43 near the cup opening 13. The blades in the upper blade assembly 42 are inclined. Towards the side away from the blade shaft 41, the blades in the upper blade assembly 42 gradually approach the lower blade assembly 43. This causes the food sliding along the surface of the upper blade assembly 42 to be thrown downwards and quickly enter the mixing range of the lower blade assembly 43, improving the mixing efficiency of the food.

[0032] Please refer to Figure 1A limiting groove 411 is provided at one end of the cutter shaft 41 near the bottom wall 11. A limiting block 111 is provided on the bottom wall 11 inside the cavity 14 and engages with the limiting groove 411. A sealing ring (not shown in the figure) can be provided between the limiting block 111 and the limiting groove to prevent leakage of lubricant or food. A bearing (not shown in the figure) can be provided between the limiting block 111 and the limiting groove. The bearing can be a deep groove ball bearing. The limiting block 111 can be connected to the bottom wall 11 by bolts (not shown in the figure) for easy disassembly and maintenance.

[0033] Preferably, a lid 2 is provided at the mouth 13 of the cup. The lid 2 seals the cup body 1, and a sealing ring (not shown in the figure) can be provided between the lid 2 and the cup body 1 to fill the gap between the lid 2 and the cup body 1. A main unit 3 is also provided on the lid 2. The main unit 3 is connected to the stirring mechanism 4, and the torque output by the main unit 3 drives the blade shaft 41 to rotate, thereby rotating the blades in the upper blade assembly 42 and the lower blade assembly 43.

[0034] Specifically, the main unit 3 includes a motor 31, a gearbox 32 connected to the motor 31, and a safety switch 321. The motor 31 allows for precise speed adjustment via circuitry to accommodate different types of ingredients. The stirring mechanism 4 is connected to the motor 31 via the gearbox 32, which adjusts the speed and torque output by the motor 31. The gearbox 32 can be a gear transmission 32.

[0035] The specific workflow of this utility model is as follows: Open the lid 2, place the ingredients into the cavity 14, and then close the lid 2 and the cup body 1. Start the motor 31. The motor 31 outputs torque to drive the blade shaft 41 to rotate, which in turn drives the blades in the upper blade group 42 and the lower blade group 43 to rotate around the blade shaft 41 and continuously agitate the ingredients. During agitation, centrifugal force is generated to continuously push the ingredients towards the side wall 12, moving the ingredients away from the agitation area of ​​the stirring mechanism 4 until they contact the side wall 12. Some of the ingredients at the bottom are agitated by the first blade 431 and move upward, while another part slides upward along the surface of the bend 432 and is thrown out. Under the combined action of centrifugal force and the first blade 431, the ingredients move upward along the side wall 12. When the ingredients reach the return section 121, the return section 121 pushes the ingredients towards the blade shaft 41. Until the ingredients fall back into the agitation range of the stirring mechanism 4 under the action of gravity. The motor 31 continues to run, and the ingredients in the cavity 14 continue to tumble and move up and down, quickly completing the agitation of the ingredients.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
