Description

Technical Field

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

[0002] Food processors, such as meat grinders, generally consist of a bowl and a mixing blade. Bowls with a mixing chamber typically have the largest size at the rim, gradually decreasing in size from the rim to the bottom; for example, a bowl with an inverted trapezoidal shape. Other bowls are cylindrical with the same size from rim to bottom. In both of these shapes, when the mixing blades are used to grind food, the food easily splashes towards the rim. Summary of the Invention

[0003] This application provides a bowl for a food processor and the food processor itself, which can reduce food splashing towards the rim of the bowl.

[0004] A food processor bowl includes a bowl body and a mixing blade rotatably disposed within the bowl body.

[0005] The stirring blade includes a blade shaft and one or more blades disposed on the blade shaft.

[0006] The bowl body includes a bowl bottom, an outwardly expanding section that gradually extends upward and outward from the bowl bottom, and an inwardly contracting section that gradually extends upward and inward from the outwardly expanding section. The top of the inwardly contracting section is higher than the highest blade on the cutter shaft. The diameter of the bowl body is largest at the junction of the outwardly expanding section and the inwardly contracting section, and the difference between the largest diameter and the diameter at the top of the inwardly contracting section is 5 to 15 mm.

[0007] The bowl body provided in this application has a gradually decreasing diameter from the junction of the expanding and contracting sections. When the mixing blade is working, the food adheres to the inner wall of the bowl body under the agitation of the blade and gradually flows from the bottom to the rim. After passing the junction of the expanding and contracting sections, due to the inward contraction of the contracting section, at least some of the food's own weight overcomes the adhesion between itself and the inner wall of the bowl body, causing this portion of food to fall off the inner wall and re-enter the mixing chamber. This allows for repeated agitation of the fallen food and reduces the amount of food overflowing the rim. Furthermore, the top of the contracting section is positioned higher than the highest point of the blade on the blade shaft, which facilitates the re-entry of food near the rim into the mixing chamber after passing the junction P, increasing the likelihood of repeated agitation. The difference between the maximum diameter and the diameter of the top of the contracting section is 5-15 mm, which limits the inclination or curvature of the contracting section, making the inclination or curvature of the contracting section more appropriate and reducing the accumulation of food in the contracting section.

[0008] Optionally, the top of the converging section is higher than the highest blade on the blade shaft, with a height difference of 30mm to 40mm. This can reduce the amount of food flying out of the bowl during the mixing process and also reduce the accumulation of food in the converging section.

[0009] Optionally, the blades are provided in multiple parts, one of which is a first blade located at the highest point of the blade shaft. Along the axial direction of the blade shaft, the distance between the first blade and the maximum diameter of the bowl body is less than or equal to 5 mm. This setting can limit the position of the first blade relative to the bowl body, preventing the first blade from being too high and reducing the chance of food splashing out of the bowl during mixing. It can also prevent the first blade from being too low, which would reduce the mixing space.

[0010] Optionally, the bowl body also includes a rim at the top, with the rim formed by the top end of the tapering section. This design allows for a simpler bowl shape and easier manufacturing.

[0011] Optionally, the bowl body further includes a rim at the top, and an extension extending upward from the top of the concave section, the top of the extension forming the rim. The extension facilitates the transition between the concave section and the rim, allowing for proper positioning and fit between the bowl body and the lid.

[0012] Optionally, the extension section has an annular cylindrical structure. This structure is simple and easy to manufacture.

[0013] Optionally, the extension section has a non-cylindrical structure that is wider at the top and narrower at the bottom. This structure can provide support for the bowl lid.

[0014] Optionally, the bowl body further includes a baffle protruding from the inner wall. The baffle extends upward from the bottom of the bowl, passing through the junction of the outwardly expanding section and the inwardly contracting section. Below the junction, the end face of the baffle in the protruding direction gradually extends upward and outward, and above the junction, the end face gradually extends upward and inward. This causes food adhering to the baffle to fall off as the end face of the baffle gradually bends towards the blade shaft, which is beneficial for repeated mixing of the food.

[0015] Optionally, the blades are provided in multiple parts, at least one of which is a second blade higher than the lower end of the turbulence rib and lower than the upper end of the turbulence rib. A gap of 2-10 mm is provided between the end of the second blade and the end face along the blade axis radially. This arrangement allows for a smaller gap between the blade and the turbulence rib, increases the stirring radius, and improves the stirring efficiency.

[0016] Optionally, at least one of the blades has a gap of 2 to 10 mm radially between its tip and the inner wall of the bowl body. This arrangement allows for a smaller gap between the blade and the inner wall of the bowl body, thereby increasing the mixing space and improving mixing efficiency.

[0025] 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.

[0026] 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 movements between 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.

[0027] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a food processor 100 shown as an exemplary embodiment of this application.

[0028] This application provides a food processor 100, which includes a main unit 10 and a bowl 20, wherein the main unit 10 and the bowl 20 are detachably connected. The main unit 10 can be configured as a head unit, which is mounted on top of the bowl 20.

[0029] Please refer to Figure 2 , Figure 2 This is a cross-sectional view of the bowl 20 shown as an exemplary embodiment of this application.

[0030] The bowl body 20 includes a bowl body 21 and a stirring blade 22. The bowl body 21 forms a stirring chamber 210, and the stirring blade 22 is rotatably mounted within the stirring chamber 210 of the bowl body 21. The bowl body 20 may also include a bowl lid 23 (see reference). Figure 1 The bowl lid 23 covers the top of the bowl body 21, the main unit 10 is supported by the bowl lid 23, and is connected to the stirring blade 22 through the hole on the bowl lid 23.

[0031] The stirring blade 22 includes a blade shaft 220 and blades 221 disposed on the blade shaft 220. One or more blades 221 can be provided, and multiple blades 221 can be disposed at different heights on the blade shaft 220. A connector 223 is provided at the top of the blade shaft 220, and the main unit 10 is connected to the connector 223 for transmission, thereby driving the stirring blade 22 to rotate. Alternatively, a bowl shaft 24 can be provided at the bottom of the bowl body 21. The bowl shaft 24 is coaxial with the blade shaft 220, and the bowl shaft 24 mates with a hole at the bottom of the blade shaft 220, which can reduce the amount of shaking when the stirring blade 22 rotates.

[0032] The bowl body 21 also includes a bowl bottom 211, a bowl mouth 212, an outwardly expanding section 213, and an inwardly contracting section 214. The bowl bottom 211 is located at the bottom of the bowl body 21, and its shape is designed to be stably supported by a tabletop, including but not limited to a flat bowl bottom 211. The bowl mouth 212 is located at the top of the bowl body 21, forming the opening of the bowl body 21. The stirring blade 22 can be inserted into the stirring chamber 210 from the bowl mouth 212, and ingredients are also placed into the stirring chamber 210 from the bowl mouth 212.

[0033] The expanding section 213 is cylindrical and gradually extends upward and outward from the bottom 211 of the bowl; that is, the diameter of the expanding section 213 gradually increases from bottom to top. In one embodiment, the expanding section 213 is cut with a longitudinal section passing through the axis of the tool shaft, and the section is a straight upward and outward extending section. In another embodiment, the expanding section 213 is cut with a longitudinal section passing through the axis of the tool shaft, and the section is an arc-shaped upward and outward extending section.

[0034] The converging section 214 is cylindrical and connected to the upper end of the expanding section 213, gradually extending upwards and inwards from the expanding section 213; that is, the diameter of the converging section 214 gradually decreases from bottom to top. In one embodiment, the converging section 214 is cut with a longitudinal section passing through the cutter shaft axis, and the section is a straight upward and inwardly extending section. In another embodiment, the converging section 214 is cut with a longitudinal section passing through the cutter shaft axis, and the section is an arc-shaped upward and inwardly extending section. The space enclosed by the expanding section 213 and the converging section 214 is the stirring chamber 210. The top end 2140 of the converging section 214 is higher than the highest blade on the cutter shaft 220. The bowl 212 can be formed at the top end 2140 of the converging section 214, but is not limited to this.

[0035] As described above, the diameter of the bowl body 21 gradually decreases from the junction P of the expanding section 213 and the contracting section 214. When the stirring blade 22 is working, the ingredients adhere to the inner wall of the bowl body 21 under the stirring action of the stirring blade 22, and gradually flow from the bottom 211 to the mouth 212. After the ingredients pass through the junction P of the expanding section 213 and the contracting section 214, due to the contraction of the contracting section 214, at least part of the ingredients will overcome the adhesion between themselves and the inner wall of the bowl body 21. This part of the ingredients will fall from the inner wall of the bowl body 21 and fall back into the stirring chamber 210. This allows the fallen ingredients to be repeatedly stirred, and also reduces the amount of ingredients flowing out of the mouth 212.

[0036] The diameter B of the bowl body 21 is largest at the junction P of the outwardly expanding section 213 and the inwardly contracting section 214. The difference between the maximum diameter B and the diameter A of the top 2140 of the inwardly contracting section 214 is 5-15 mm. This setting can limit the slope or curvature of the inwardly contracting section 214. If the difference in diameter is small, the slope of the inwardly contracting section 214 will be large, which will reduce the effect of food flipping and falling at the junction P. If the difference in diameter is large, the slope of the inwardly contracting section 214 will be too small, which will cause food to accumulate on the top of the inwardly contracting section 214. When the diameter difference is 5-15 mm, the slope or curvature of the inwardly contracting section 214 is more appropriate.

[0037] When the blade 221 is stirring, it causes the food to flip and flow toward the bowl opening 212. In this application, the top end 2140 of the concave section 214 is set higher than the highest point of the blade 221 on the blade shaft 220, which is conducive to more food falling back into the stirring chamber 210 after passing the connecting part P, increasing the probability of the food being repeatedly stirred.

[0038] In one embodiment, the top end 2140 of the converging section 214 is higher than the highest blade 221 on the blade shaft 220, with a height difference H of 30mm-40mm. If the height difference H is too small, the food can easily fly out of the bowl opening 212 during mixing; if the height difference H is too large, the food may accumulate on the upper part of the converging section 214. The height difference H can be set to 30mm, 32mm, 34mm, 35mm, 36mm, 38mm, or 40mm.

[0039] exist Figure 2 In the embodiment shown, the cutter shaft 220 is provided with a plurality of blades 221, which are spaced apart along the axial direction of the cutter shaft. The height of the contact portion P is higher than the height of all the blades 221.

[0040] In one specific embodiment, the difference between the maximum diameter B and the diameter of the top end 2140 of the inward section 214 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm, but is not limited to these.

[0041] In one embodiment, multiple blades 221 are provided, one of which is a first blade 221a located at the highest point of the blade shaft 220. Along the axial direction of the blade shaft 220, the distance between the first blade 221a and the maximum diameter of the bowl body 21 is less than or equal to 5mm. That is, the first blade 221a can be within 5mm above or below the maximum diameter of the bowl body 21. This setting can limit the position of the first blade 221a relative to the bowl body 21, preventing the first blade 221a from being too high, reducing the probability of food splashing out of the bowl opening 212 during mixing, and also preventing the first blade 221a from being too low, thus reducing the mixing space. It should be noted that the maximum diameter can be set at 1 / 2 the height of the bowl body 21, but it is not limited to this.

[0042] In one embodiment, at least one blade 221 has a radial gap of 2 to 10 mm between its tip and the inner wall of the bowl body 21. This arrangement allows for a smaller gap C between the blade 221 and the inner wall of the bowl body 21, thereby increasing the stirring radius and improving the stirring efficiency. This gap C can be, for example, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0043] exist Figure 2In the embodiment shown, there are multiple blades 221. One of the multiple blades 221 is closest to the bottom of the bowl 211. The blade 221 that is closest to the bottom of the bowl 211 is provided with a gap of 2 to 10 mm in the radial direction of the blade axis between it and the inner wall of the bowl body 21. In this way, more food at the bottom of the bowl 211 can be stirred and turned by the blade 221, and the food is easier to be crushed.

[0044] In one embodiment, such as Figure 2 As shown, the bowl body 21 also includes a baffle 2110 protruding from the inner wall. The baffle 2110 extends from the bottom 211 of the bowl towards the rim 212, with its bottom end higher than the bottom 211 and its top end lower than the rim 212. The specific number of baffles 2110 is not limited. For example, multiple baffles 2110 can be arranged at intervals to improve the mixing effect.

[0045] The baffle 2110 passes through the junction of the outwardly expanding section 213 and the inwardly contracting section 214. Below the junction P, the end face 2110a of the baffle 2110 gradually extends upward and outward in the convex direction. Above the junction P, the end face 2110a gradually extends upward and inward. The end face 2110a is the end face of the baffle 2110 facing the blade shaft 220. This end face 2110a gradually extends upward and outward from the bottom end, and then extends upward and inward from the junction P. Along the direction from the bottom 211 of the bowl to the rim 212 of the bowl, the direction of this end face 2110a is the same as the direction of the outer contour surface of the outwardly expanding section 213 and the inwardly contracting section 214. This allows the food adhering to the baffle 2110 to fall off as the end face 2110a of the baffle 2110 gradually bends towards the blade shaft 220, which is beneficial for repeated mixing of the food.

[0046] In one embodiment, such as Figure 2 As shown, the blades 221 are provided in multiple configurations, at least one of which is a second blade 221b that is higher than the lower end of the turbulence rib 2110 and lower than the upper end of the turbulence rib 2110. A gap of 2–10 mm is provided between the end of the second blade 221b and the end face 2110a along the blade axis radially. For example, the gap D can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. This configuration allows for a smaller gap between the blades 221 and the turbulence rib 2110, thereby increasing the mixing space and improving the mixing efficiency.

[0047] exist Figure 2In the illustrated embodiment, four blades 221 are provided, arranged from high to low on the cutter shaft 220. The first blade 221a, located at the highest point, and the second blade 221b, whose height is second only to the first blade 221a, are respectively positioned between the two ends of the baffle 2110. A gap of 2 to 10 mm is provided between each blade 221 and the end face 2110a along the radial direction of the cutter shaft. The first blade 221a and the second blade 221b can be spaced 180° apart, but are not limited to this.

[0048] In one embodiment, such as Figure 2 As shown, the bowl body 21 also includes an extension section 216 extending upward from the top end 2140 of the inward section 214, the top end of the extension section 216 forming the rim 212 of the bowl body 21. The extension section 216 facilitates the transition between the inward section 214 and the rim 212, and the extension section 216 facilitates the positioning and engagement of the bowl body 20 and the bowl lid 23.

[0049] In one specific embodiment, the extension segment 216 has an annular cylindrical structure or a non-cylindrical structure that is larger at the top and smaller at the bottom. Figure 2 In the embodiment shown, the extension 216 has an annular straight cylindrical structure, which is simple and easy to process.

[0050] Please refer to Figure 3 , Figure 3 This is a cross-sectional view of another embodiment of the bowl.

[0051] In one embodiment, such as Figure 3 As shown, the extension section 216 is stepped, comprising a conical end 2160 connected to the inward section 214 and a straight section 2161 connected above the conical end 2160. The smaller end of the conical end 2160 connects to the inward section 214, and the larger end of the conical end 2160 connects to the straight section 2161. This stepped structure provides support for the bowl lid 23. The extension section 216 can be selected according to actual needs, such as to accommodate bowl lids 23 of different shapes.

[0052] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 This is a cross-sectional view of another embodiment of the bowl body 20.

[0053] exist Figure 4 and Figure 5 In the illustrated embodiment, the top end 2140 of the inwardly tapering section 214 forms the bowl rim 212. This design allows for a simpler shape for the bowl body 20 and reduces manufacturing difficulty.

[0054] exist Figure 4In the example shown, the outwardly expanding section 213 and the inwardly receding section 214 are symmetrical about the centerline at half the height of the bowl body 21, resulting in better uniformity of the shape. For example, the outer contour surfaces of the outwardly expanding section 213 and the inwardly receding section 214 are both part of a sphere and are symmetrical about the centerline at half the height of the bowl body 21.

[0055] exist Figure 5 In the example shown, the radius of curvature of the outwardly expanding segment 213 is at least partially smaller than the radius of curvature of the inwardly contracting segment 214. Figure 5 In the example shown, the outward expansion section 213 includes a first outward expansion section 2130 connected to the bottom of the bowl 211 and a second outward expansion section 2131 connected to the inward contraction section 214. The radius of curvature of the first outward expansion section 2130 is smaller than the radius of curvature of the second outward expansion section 2131.

[0056] In one embodiment, the bowl body 21 can be integrally formed, and the forming method includes, but is not limited to, casting and extrusion. The outwardly expanding section 213 and the inwardly contracting section 214 together form the side circumference of the bowl body 21. This side circumference can be configured as an arcuate side circumference with the blade axis as its center of symmetry, or as a spherical side circumference with the blade axis as its center of symmetry. That is, the outwardly expanding section 213 and the inwardly contracting section 214 have a smooth transition, which makes the inner wall of the side circumference also smooth, making it easier for food adhering to the inner wall to fall off.

[0057] exist Figures 2 to 5 In the embodiment shown, the top of the bowl body 21 is also provided with an annular flange 217, which can be used to support the bowl lid and also facilitates the removal of the bowl body 20.

[0058] 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.
