Description

Technical Field

[0001] This application relates to the field of bowl assembly technology, and more specifically, to a bowl lid and a food processor. Background Technology

[0002] When a food processor blends ingredients, it generates centrifugal force. The ingredients are thrown against the inner walls of the bowl and lid due to the high-speed rotation. Some ingredients may stick to the inner wall of the lid, preventing them from being fully blended, which reduces the user experience. Utility Model Content

[0003] This application provides a bowl lid and a food processor that can reduce food sticking to the inner wall of the bowl lid, thereby improving the user experience.

[0004] In a first aspect, this application provides a bowl lid, including a bowl lid body; the bowl lid body has an inner wall facing the bowl and a through hole for a knife shaft to pass through, the through hole being located in the middle of the bowl lid body; the inner wall is arc-shaped, the inner wall extends from the edge of the inner wall toward the through hole, and the height of the edge of the inner wall is higher than the height of the through hole.

[0005] In this design, because the inner wall of the lid is curved, the contact between the food and the lid is primarily point- or line-like. The food generally contacts the inner wall at the tangent point and a small area near that point. This reduces the effective contact area between the food and the bottom of the lid, effectively minimizing food sticking to the inner wall and improving the user experience. Furthermore, since the inner wall extends from the edge towards the opening, some food adhering to the inner wall can gather along the inner wall towards the opening in the center and fall off. The stirring blade located at the opening can directly stir and pulverize this food, improving the food processor's blending effect.

[0006] Optionally, the inner wall includes a sequentially connected edge portion, a transition portion, and a central portion. The radius of the edge portion is R1, the radius of the transition portion is R2, and the radius of the central portion is R3; wherein R2 is smaller than R1 and smaller than R3. With this configuration, the radius R2 of the transition portion is smaller, resulting in a relatively steeper curvature. At the same horizontal distance, the vertical distance the inner wall extends from the edge portion to the central portion changes more rapidly, which helps to reduce the overall height of the inner wall and minimize its encroachment on the space inside the bowl. Furthermore, when food slides from the edge portion through the transition portion, the steeper curvature accelerates the sliding speed. This design encourages food to flow more quickly from the transition portion to the central portion.

[0007] Optionally, the ratio of R1 to R2 is between 2 and 4. On the one hand, setting the upper limit of this ratio to less than or equal to 4 ensures a smoother transition between the edge and transition portions, preventing the change from being too abrupt. On the other hand, setting the lower limit of this ratio to greater than or equal to 2 keeps the descent speed of the inner wall from the edge to the center within a reasonable range, preventing it from being too slow.

[0008] Optionally, the ratio of R3 to R2 is 2-4.

[0009] Optionally, R1 is equal to R3. The radius of the edge portion is equal to the radius of the center portion, making the overall structure of the bowl lid more regular and symmetrical. For users, the visual and actual tactile experience is relatively consistent, which helps to improve the aesthetics of the bowl lid.

[0010] Optionally, the radial dimension of the inner wall gradually decreases along the direction from the top to the bottom of the lid. This means that the lid body begins to taper inward at the edge, rather than extending outward, preventing the edge of the lid body from appearing too wide. Furthermore, during the food processor's blending process, the food is thrown against the inner wall of the lid by centrifugal force. Because the radial dimension of the inner wall gradually decreases along the direction from the top to the bottom of the lid, this creates a sloped path for the food. After impacting the inner wall, the food slides down this gradually decreasing radial path into the bowl.

[0011] Optionally, the height of the inner wall is H, and the maximum radial dimension of the inner wall is 2R4, wherein H and R4 satisfy the following inequality:

[0012] That is, the diameter-to-depth ratio of the inner wall is in the range of 0.5 to 1.5, which prevents the bowl lid from being too slender or too short and stout, making the bowl lid more harmonious and beautiful in appearance.

[0013] Optional, This is to further improve the harmony and aesthetics of the bowl lid.

[0014] Optionally, the bowl lid also includes a bowl cap connected to the edge of the bowl lid body, the bowl cap extending circumferentially along the bowl lid body; wherein, the top surface of the bowl cap is provided with a trigger rib, the trigger rib being used to engage with the main unit of the food processor. The trigger rib's prominent location on the top surface of the bowl cap provides a visual installation indicator for the user. When installing the main unit onto the bowl lid, the user can easily see whether the trigger rib is aligned and in contact with the corresponding part of the main unit, thus determining whether the bowl lid and main unit are installed correctly. Furthermore, compared to a design on the curved bowl lid body, this solution eliminates protruding structures on the outer wall of the bowl lid body, resulting in a more aesthetically pleasing appearance.

[0015] Optionally, the bowl lid also includes a sealing protrusion connected to the inner wall. The sealing protrusion extends circumferentially along the inner wall and horizontally. A sealing groove is formed between the sealing protrusion and the bowl lid. The sealing groove is used to install a sealing element to seal the gap between the bowl body and the bowl lid, thereby preventing food, liquids, etc. from seeping out from the gap.

[0016] Furthermore, in this design, the bowl cap serves to house the trigger ribs and also cooperates with the sealing protrusion to form a sealing groove. In other words, this design integrates two different functions into the bowl cap, eliminating the need for additional components or structures to achieve the respective functions separately, resulting in a more compact and rational overall structure of the bowl lid.

[0017] Secondly, this application provides a food processor, comprising: a main unit; and a bowl assembly, including a bowl body and a bowl lid as described in any of the above claims, the bowl lid being disposed on the bowl body. Attached Figure Description

[0024] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0025] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0026] This application provides a bowl lid for a food processor and the food processor itself. The bowl lid and food processor are described in detail below with reference to the accompanying drawings. Features in the following embodiments and implementations can be combined with each other unless otherwise specified.

[0027] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the exploded structure of a food processor according to one embodiment; Figure 2 This is a cross-sectional diagram of a food processor.

[0028] The food processor includes a main unit 30 and a bowl assembly, which are detachably connected. The main unit 30 can be configured as a head unit 30, which is mounted on top of the bowl assembly.

[0029] The bowl assembly includes a bowl body 20, a bowl lid, and a stirring blade 40 rotatably mounted on the bowl body 20. The bowl lid covers the bowl body 20, and the rotation axis of the stirring blade 40 is aligned with the height direction of the bowl body 20. The stirring blade 40 may include one or more blades 42. A bowl shaft 21 may also be provided at the bottom of the bowl body 20, which is coaxial with the blade shaft 41 of the stirring blade 40 to reduce the amount of wobbling when the stirring blade 40 rotates.

[0030] The bowl lid includes a bowl lid body 10, which has an inner wall 11 facing the bowl body 20 and a through hole 12 for the blade shaft 41 to pass through. The through hole 12 is located in the middle of the bowl lid body 10, and the blade shaft 41 of the stirring blade 40 can pass through the through hole 12 to connect with the motor shaft of the main unit 30. The inner wall 11 of the bowl lid body 10 is arc-shaped, extending from its edge to the through hole 12 in the middle, and the height of the edge of the inner wall 11 is higher than the height of the through hole 12. In other words, the inner wall 11 of the bowl lid extends from its edge to the through hole 12 in the middle, and extends from top to bottom (the direction from top to bottom can be referenced). Figure 3 (As shown in the Y direction).

[0031] It's easy to understand that when the food processor's blade 40 is blending ingredients, the ingredients move outwards due to centrifugal force. With traditional bowl lids, the flat inner wall 11 typically adheres to the entire surface of the ingredients, making it easy for large areas of the ingredients to stick to it. In this design, because the inner wall 11 of the lid body 10 is curved, the contact with the ingredients is primarily point- or line-like. The ingredients generally contact the inner wall 11 at the tangent point and a small area near the tangent point. This reduces the effective contact area between the ingredients and the inner wall 11, effectively reducing the amount of ingredients sticking to the inner wall 11 and improving the user experience. Furthermore, since the inner wall 11 extends from the edge towards the through-hole 12, some of the ingredients sticking to the inner wall 11 can gather along the inner wall 11 towards the central through-hole 12 and fall off. The blade 40 located at the through-hole 12 can directly blend and pulverize these ingredients, improving the blending effect of the food processor.

[0032] Please refer to Figure 3 , Figure 3 This is a cross-sectional structural diagram of the bowl lid;

[0033] In one embodiment, the inner wall 11 includes an edge portion 111, a transition portion 112, and a center portion 113. The radius of the edge portion 111 is R1, the radius of the transition portion 112 is R2, and the radius of the center portion 113 is R3. R2 is less than R1 and less than R3. That is, the radius of the transition portion 112 is less than the radius of the edge portion 111, and the radius of the transition portion 112 is also less than the radius of the center portion 113. It should be noted that the radius here refers to the arc radius of the inner wall 11, not the radial radius of the inner wall 11.

[0034] With this configuration, the radius R2 of the transition section 112 is smaller, resulting in a relatively steeper curvature. At the same horizontal distance, the vertical distance of the inner wall 11 extending from the edge 111 to the center 113 changes more rapidly. This helps reduce the overall height of the inner wall 11 and minimizes its encroachment on the internal space of the bowl 20. Furthermore, when food slides from the edge 111 through the transition section 112, the steeper curvature accelerates the sliding speed. This design encourages food to flow more quickly from the transition section 112 to the center 113, and then fall from the center to be stirred by the mixing blade 40.

[0035] In one embodiment, the radius R1 of the edge portion 111 is equal to the radius R3 of the center portion 113. The equal radii of the edge portion 111 and the center portion 113 make the overall structure of the bowl lid more regular and symmetrical. For the user, the visual and actual tactile experience is relatively consistent, which helps to improve the aesthetics of the bowl lid.

[0036] Furthermore, the ratio of the radius R1 of the edge portion 111 to the radius R2 of the transition portion 112 is 2 to 4, that is, the value of R1:R2 is 2 to 4. For example, the ratio of R1 to R2 can be 2, 2.5, 3, 3.5, or 4, but is not limited thereto.

[0037] On the one hand, by setting the upper limit of the ratio to less than or equal to 4, the transition between the edge portion 111 and the transition portion 112 is relatively smooth, so that the change is not too abrupt; on the other hand, by setting the lower limit of the ratio to greater than or equal to 2, the descent speed of the inner wall 11 from the edge portion 111 to the center portion 113 is kept within a reasonable range, so as not to be too slow.

[0038] Similarly, the ratio of the radius R3 of the central portion 113 to the radius R2 of the transition portion 112 can also be 2 to 4, that is, the value of R3:R2 is 2 to 4. For example, the ratio of R3 to R2 can be 2, 2.5, 3, 3.5, or 4, but is not limited to these.

[0039] In one embodiment, in the direction from the top of the bowl lid to the bottom of the bowl lid (i.e., the direction from the bowl lid to the bowl body 20, see reference 20) Figure 3 (As shown in the Y direction), the radial direction of the inner wall 11 (please refer to the radial direction) Figure 3 The dimensions (in the X direction) gradually decrease. This indicates that the lid body 10 begins to taper inwards at the edge, rather than extending outwards, preventing the edge of the lid body 10 from appearing too wide. Furthermore, during the food processor's blending process, the ingredients are thrown against the inner wall 11 of the lid under centrifugal force. Since the inner wall 11 gradually decreases in radial dimension along the direction from the top to the bottom of the lid, it provides a constant slope for the ingredients. After impacting the inner wall 11, the ingredients slide down this gradually decreasing radial slope towards the bowl body 20.

[0040] Furthermore, the maximum radial dimension of the edge portion 111 is 2R4, where R4 is less than R1 and greater than R2.

[0041] For example, R1 is 80mm, R2 is 30mm, R3 is 80mm, and R4 is 45mm, but it is not limited to these.

[0042] In one embodiment, the height of the inner wall 11 (height direction reference) Figure 3 Let H be the Y-direction shown, and let the maximum radial dimension (X-direction dimension) of the inner wall 11 be 2R4. H and R4 satisfy the following inequality:

[0043] .

[0044] That is, the diameter-to-depth ratio of the inner wall 11 is in the range of 0.5 to 1.5, which prevents the bowl lid body 10 from being too slender or too short and stout, making the bowl lid body 10 more harmonious and beautiful in appearance.

[0045] For example, the value of the diameter-to-depth ratio The values ​​can be 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, or 1.5, but are not limited to these.

[0046] Furthermore, 2. To further improve the harmony and aesthetics of the bowl lid body 10. For example, the diameter-to-depth ratio value... It can be 1, 1.1, 1.2, but is not limited to these.

[0047] Please refer to Figure 4 and combined Figure 3 , Figure 4 This is a schematic diagram of the three-dimensional structure of the bowl lid.

[0048] In one embodiment, the bowl lid further includes a bowl cap 50 connected to the edge of the bowl lid body 10. The bowl cap 50 extends circumferentially and outwards along the bowl lid body 10. A trigger rib 60 is provided on the top surface of the bowl cap 50, which engages with the main unit 30 of the food processor. For example, the main unit 30 has a trigger structure corresponding to the trigger rib 60. When the main unit 30 is assembled onto the bowl lid, the trigger rib 60 can contact the trigger structure on the main unit 30, thereby completing the circuit connection and enabling the main unit 30 to operate normally. For example, during the assembly of the food processor, the trigger rib 60 can only function after the bowl lid and the main unit 30 are properly assembled, allowing key components such as the motor to start operating. This fundamentally avoids accidental injuries such as motor idling or potential user injury caused by the user accidentally activating the motor switch before the components are properly installed. Furthermore, the prominent location of the trigger rib 60 on the top surface of the bowl cap 50 provides a clear installation guide for the user. When installing the bowl lid onto the main unit 30, the user can easily see whether the trigger rib 60 is aligned and in contact with the corresponding part of the main unit 30, thus determining whether the bowl lid and the main unit 30 are installed correctly. At the same time, compared to setting it on the curved bowl lid body 10, this design makes the outer wall of the bowl lid body 10 free of protruding structures, which is more aesthetically pleasing.

[0049] The number of trigger ribs 60 can be at least one, for example, it can be 1, 2, 3, 4, 5, etc.

[0050] In one embodiment, the bowl lid further includes a sealing protrusion 13 connected to the inner wall 11 of the bowl lid body 10. The sealing protrusion 13 is located at the edge portion 111 of the inner wall 11 and extends circumferentially along the inner wall 11. A sealing groove 70 is formed between the sealing protrusion 13 and the bowl cap 50. A sealing element 80 is provided in the sealing groove 70. The sealing element 80 may be, but is not limited to, a sealing ring, to seal the gap between the bowl body 20 and the bowl lid, thereby preventing food, liquids, etc. from seeping out from the gap.

[0051] Furthermore, the bowl cap 50 is not only used to set the trigger rib 60, but also cooperates with the sealing protrusion 13 to form a sealing groove 70. That is, this solution integrates two different functions into the bowl cap 50, without adding too many extra parts or structures to achieve the corresponding functions, making the overall structure of the bowl cap more compact and reasonable.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
