Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of small household appliances, in particular to a bowl assembly and a food processor. BACKGROUND

[0002] A food processor, such as a meat grinder, generally includes a bowl body and a stirring blade. The bowl body provided with a stirring cavity is usually of a trapezoidal shape, i.e., the size of the bowl body is largest at the bowl opening and gradually decreases from the bowl opening to the bowl bottom. There are also bowl bodies of a straight cylindrical shape, i.e., the size of the bowl body is the same from the bowl opening to the bowl bottom. When the stirring blade stirs the food material, the food material is easily splashed to the bowl opening in the above two types of bowl bodies. SUMMARY

[0003] The present application provides a bowl assembly and a food processor, which is beneficial to the falling of the food material splashed to the bowl cover, so that the food material is repeatedly stirred.

[0004] A bowl assembly, comprising:

[0005] a bowl body including a bowl main body and a stirring blade rotatably arranged in the bowl main body, the bowl main body including a bowl bottom at the bottommost part and an outward expansion section connected to the bowl bottom, the outward expansion section being arranged as a cylindrical body with the rotation shaft of the stirring blade as the central axis and the diameter gradually increasing upwards from the bowl bottom;

[0006] a bowl cover covering the bowl main body, the bowl cover including an inward contraction section arranged as a cylindrical body with the rotation shaft of the stirring blade as the central axis and the diameter gradually decreasing from one end close to the bowl main body to the other end away from the bowl main body, the space surrounded by the inward contraction section and the space surrounded by the outward expansion section jointly forming a stirring cavity, and in any cross section of the inward contraction section and the outward expansion section taken by a plane passing through the rotation shaft of the stirring blade, the contour line of the inner surface of the inward contraction section and the outward expansion section on one side of the rotation shaft of the stirring blade is located on a first circle, and the contour line of the inner surface of the inward contraction section and the outward expansion section on the other side of the rotation shaft of the stirring blade is located on a second circle.

[0007] The bowl assembly provided by the present application has the inward contraction section of the bowl cover extending upwards and inwards to form a constricted inner wall. When the food material rolls upwards and flows towards the inner wall of the inward contraction section during the stirring process, the weight of at least part of the food material will overcome the adhesion of the food material to the inner wall of the inward contraction section, and this part of the food material will fall down from the inner wall of the inward contraction section and fall into the stirring cavity again, so that the falling food material can be repeatedly stirred. In addition, the contour line of the inner surface of the inward contraction section and the outward expansion section on the left side of the rotation shaft of the stirring blade is located on a first circle, and the contour line of the inner surface of the inward contraction section and the outward expansion section on the right side of the rotation shaft of the stirring blade is located on a first circle, which makes the food material less likely to adhere to the arc-shaped surface and more likely to slide down along the arc-shaped surface, further increasing the probability of repeated stirring of the food material.

[0008] Optionally, the center of the stirring cavity is located on the rotation shaft of the stirring blade, and the distance between the center of the stirring cavity and the uppermost blade of the stirring blade is 0-10mm. In this way, the distance between the uppermost blade and the inwardly converging section can be limited, and the food material flipped up by the uppermost blade can be ensured to fall down by colliding with the inwardly converging section. Optionally, the distance between the center of the stirring cavity and the top end of the inwardly converging section is 20-40mm. In this way, the top end of the inwardly converging section can be ensured to be higher than the uppermost blade, and when the uppermost blade flips up the food material upward, the food material has a greater probability of contacting and colliding with the inner wall of the inwardly converging section, thereby increasing the probability of the food material falling down.

[0009] Optionally, the top end of the outwardly diverging section is formed as the bowl opening of the bowl body. The bowl body has a simple structure and is easy to process.

[0010] Optionally, the contour line of the inner surface of the inwardly converging section and the outwardly diverging section on one side of the rotation shaft of the stirring blade is symmetrical about the rotation shaft of the stirring blade with the contour line of the inner surface of the inwardly converging section and the outwardly diverging section on the other side of the rotation shaft of the stirring blade. This makes the internal space of the stirring cavity uniform, and the inner surface contour of the inwardly converging section and the outwardly diverging section is the same everywhere, which is conducive to the food material being stirred and rolled upward along the inner wall of the stirring cavity to fall down from any part of 360°.

[0011] Optionally, the first circle and the second circle coincide. In this way, the curvature of the inner surface of the inwardly converging section and the outwardly diverging section is increased, the bending degree of the inner surface is greater, and the ability of the food to adhere to the inner surface of the inwardly converging section and the outwardly diverging section is reduced.

[0012] Optionally, the diameters of the first circle and the second circle are equal, and the centers are different. In this way, the curvature of the inner surface of the inwardly converging section and the outwardly diverging section is relatively small, and the bending degree of the inner surface is smaller. This can not only make the food material fall down, but also facilitate the cleaning of the inner surface of the bowl body and the bowl cover.

[0013] Optionally, the smallest end of the diameter of the inwardly converging section is provided as the bottom end of the bowl cover, the bottom end of the bowl cover is covered by the outwardly diverging section, and the bottom end is also supported on the outwardly diverging section. In this way, the covering structure can make the bowl cover and the bowl body cover more tightly, and the spilling effect is good. The bowl cover is supported on the outwardly diverging section, and the covering position is stable and reliable.

[0014] Optionally, the bowl cover further comprises a top cover connected to the top end of the inwardly converging section, the top cover comprises a cylindrical section with the rotation shaft of the stirring blade as the central axis and a cover plate sealed to the top of the cylindrical section, and the cover plate is provided with a through hole for the stirring blade to extend out. The cylindrical section can increase the height of the bowl cover, and correspondingly increase the space in the stirring cavity and the capacity of the food material.

[0015] A food processor comprises:

[0016] A main machine;

[0017] A bowl assembly arranged below the main machine, the main machine being mounted on a bowl cover, and a stirring blade being in transmission connection with the main machine. BRIEF DESCRIPTION OF DRAWINGS

[0025] Please refer to Figure 1 , Figure 1 is a sectional view of a food processor 100 according to an exemplary embodiment of the present application.

[0026] The present application provides a food processor 100, which comprises a main machine 10 and a bowl assembly 20, and the main machine 10 is detachably connected with the bowl assembly 20. The main machine 10 can be arranged as a head-type main machine, and the main machine 10 is mounted above the bowl assembly 20.

[0027] Referring to Figure 2 and Figure 3 , Figure 2 is an exploded view of the bowl assembly 20 according to an exemplary embodiment of the present application. Figure 3 is Figure 2 is a cross-sectional view of the bowl assembly 20 according to an exemplary embodiment of the present application.

[0028] The bowl assembly 20 includes a bowl body 21 and a bowl cover 22. The bowl body 21 includes a bowl main body 210 and an agitator 211 rotatably arranged in the bowl main body 210. The rotation axis of the agitator 211 is aligned with the height direction of the bowl main body 210. The agitator 211 can include one or more blades 2111. For example, a bowl shaft 23 can be arranged at the bottom of the bowl main body 210. The bowl shaft 23 is coaxial with the blade shaft 2110 of the agitator 211. The bowl shaft 23 is fitted with a hole at the bottom end of the blade shaft 2110, which can reduce the amount of shaking of the agitator 211 when it rotates.

[0029] The bowl cover 22 covers the bowl main body 210. For example, the bowl cover 22 can be supported on a flange 2104 protruding radially from the bowl main body 210. The flange 2104 can be provided with two protrusions, which are spaced 180° apart, but is not limited thereto.

[0030] The bowl main body 210 includes a bowl bottom 2100 and an outwardly expanding section 2102 connected to the bowl bottom 2100. The outwardly expanding section 2102 is arranged as a cylindrical body with the rotation axis O of the agitator 211 as the central axis and the diameter gradually increasing upward from the bowl bottom 2100. In this way, the bowl main body 210 is extended outwardly, which can increase the volume inside the bowl main body 210. The outwardly expanding section 2102 can be straight and extend upward and outward, or can be arc-shaped and extend upward and outward.

[0031] The bowl cover 22 includes an inwardly contracting section 220 arranged as a cylindrical body with the rotation axis O of the agitator 211 as the central axis and the diameter gradually decreasing upward from the end close to the bowl main body 210 to the end away from the bowl main body 210, as shown in Figure 3 The diameter of the inwardly contracting section 220 gradually decreases upward from the bottom. The inwardly contracting section 220 can be straight and extend upward and inward, or can be arc-shaped and extend upward and inward. The space enclosed by the inwardly contracting section 220 and the space inside the outwardly expanding section 2102 together form an agitator chamber 2101.

[0032] According to the above description, the inwardly-retracted section 220 of the bowl cover 22 extends upwardly and inwardly to form a constricted inner wall. When the food materials are rolled upwardly and surge toward the inner wall of the inwardly-retracted section 220 during the whipping process, the weight of at least part of the food materials will overcome the adhesion of the food materials to the inner wall of the inwardly-retracted section 220, and the food materials will fall from the inner wall of the inwardly-retracted section 220 and re-enter the stirring cavity 2101, so that the falling food materials can be repeatedly whipped.

[0033] In one embodiment, the center A of the stirring cavity 2101 is located on the rotation shaft of the stirring blade 211, and the distance H between the center A and the uppermost blade of the stirring blade 211 is 0-10 mm. That is, the uppermost blade can be located above or below the center A of the stirring cavity 2101, or can be flush with the center A of the stirring cavity 2101. In this way, the distance between the uppermost blade and the inwardly-retracted section 220 can be limited, and it is ensured that the food materials flipped by the uppermost blade will fall down by colliding with the inwardly-retracted section 220. The distance H can be 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm, but is not limited thereto.

[0034] In one embodiment, the top end 2200 of the inwardly-retracted section 220 is higher than the center A of the stirring cavity 2101, and the distance L between the center A of the stirring cavity 2101 and the top end 2200 of the inwardly-retracted section 220 is 20-40 mm. In this way, it is ensured that the top end 2200 of the inwardly-retracted section 220 is higher than the uppermost blade, and it is ensured that the food materials flipped upwardly by the uppermost blade have a greater probability of contacting and colliding with the inner wall of the inwardly-retracted section 220, thereby increasing the probability of the food materials falling down. The distance L between the center A of the stirring cavity 2101 and the top end 2200 of the inwardly-retracted section 220 can be 20 mm, 22 mm, 25 mm, 28 mm, 30 mm, 32 mm, 35 mm, 38 mm, or 40 mm.

[0035] In one embodiment, the smallest end of the diameter of the inwardly-retracted section 220 is arranged at the bottom end 202 of the bowl cover 22, the bottom end of the bowl cover is covered by the outwardly-expanded section 2102, and the bottom end is also supported on the outwardly-expanded section 2102. In this way, the covering structure can make the bowl cover 22 and the bowl body 210 more tightly cover each other, and the anti-overflow effect is good. The bowl cover 22 is supported on the outwardly-expanded section 2102, and the covering position is stable.

[0036] Please refer to Figure 4 , Figure 4 a cross-sectional view of the bowl assembly 20 shown in another exemplary embodiment of the present application.

[0037] In one embodiment, in any cross-section obtained by cutting the converging section 220 and the expanding section 2102 through the plane passing through the axis of rotation O of the stirring blade 211, the cross-section located on one side of the axis of rotation O of the stirring blade 211 ( Figure 4 The contour line B1 of the inner surface of the converging section 220 and the expanding section 2102 on the left side of the central shaft O is located on the first circumference S1, and on the other side of the rotating shaft O of the stirring blade 211. Figure 4 The contour line B2 of the inner surface of the concave section 220 and the convex section 2102 on the right side of the rotating shaft O is located at the second circumference S2. That is, within a 360° range around the rotating shaft O, the inner surfaces of both the concave section 220 and the convex section 2102 are arc-shaped surfaces. This makes it less likely for food to adhere to the arc-shaped surface, allowing it to slide down along the arc-shaped surface, further increasing the probability of the food being repeatedly blended.

[0038] exist Figure 4 In the illustrated embodiment, the contour line B1 of the inner surface of the converging section 220 and the expanding section 2102 located on the left side of the rotating shaft O of the stirring blade 211, and the contour line B2 of the inner surface of the converging section 220 and the expanding section 2102 located on the right side of the rotating shaft O of the stirring blade 211 are symmetrical about the rotating shaft O of the stirring blade 211. This makes the internal space of the stirring chamber 2101 uniform, and the inner surface contours of the converging section 220 and the expanding section 2102 are the same everywhere, which is beneficial for the ingredients that are stirred and rolled upward along the inner wall of the stirring chamber 2101 to fall from any part of 360°.

[0039] In one embodiment, the first circumference S1 coincides with the second circumference S2, that is, the inner surfaces of the concave section 220 and the convex section 2102 are part of a sphere. This is beneficial to increase the curvature of the inner surfaces of the concave section 220 and the convex section 2102. In other words, the inner surface is more curved, and the ability of food to adhere to the inner surfaces of the concave section 220 and the convex section 2102 is reduced.

[0040] In this embodiment, the diameters of the first circumference S1 and the second circumference S2 are equal, but their center positions are different. With this configuration, the curvature of the inner surface of the concave section 220 and the convex section 2102 is relatively small, and the degree of bending of the inner surface is less. This allows food to fall off and also facilitates cleaning of the inner surfaces of the bowl body 210 and the bowl lid 22.

[0041] In one embodiment, the top end of the outwardly expanding section 2102 is formed as the rim of the bowl body 210. This configuration simplifies the structure of the bowl body 210 and facilitates its processing.

[0042] exist Figure 4In the shown embodiment, the bowl cover 22 further comprises a top cover 221 connected to the top end 2200 of the inner receiving section 220, the top cover 221 comprises a cylindrical section 2211 with the rotation axis O of the stirring blade 211 as the central axis and a cover plate 2212 sealed to the top of the cylindrical section 2211, the cover plate 2212 is provided with a through hole 22120 for the blade shaft of the stirring blade 211 to extend out. In the shown embodiment, the central region of the cover plate 2212 is concave downward, and the through hole 22120 is arranged at the concave region of the cover plate 2212. In the shown embodiment, the cylindrical section 2211 can increase the height of the bowl cover 22, and accordingly, the space in the stirring cavity 2101 can be increased, and the capacity of the food materials can be increased. The cover plate 2212 can be arranged as an arc-shaped cover plate, and the closer to the concave region, the more protruding upward. In the shown embodiment, the main machine 10 can be arranged at the concave region of the cover plate 2212.

[0043] In one embodiment, the cylindrical section 2211 is arranged as a cylindrical structure with equal diameter. This structure is simple and easy to realize. Of course, in some other embodiments, the cylindrical section 2211 can be arranged as a tapered cylindrical structure with the diameter decreasing from bottom to top.

[0044] The bowl cover 22 can further comprise a handle 223, which facilitates the user to take the bowl cover 22, and the handle 223 can be arranged corresponding to the flange 2104 on the bowl body 210, and the handle 223 can be supported on the flange 2104.

[0045] Please refer to Figure 5 , Figure 5 a cross-sectional view of the bowl assembly 20 shown in another exemplary embodiment.

[0046] In Figure 5 In the shown embodiment, the stirring blade 211 comprises four blade pieces 2111, which are fixedly arranged at different heights of the blade shaft 2110 of the stirring blade 211, and the radial dimension of the two blade pieces close to the bowl bottom 2100 is greater than that of the two blade pieces close to the bowl bottom 2100.

[0047] Of course, the number and arrangement of the blade pieces 2111 can be different, Figure 3 In the shown embodiment, the stirring blade 211 comprises three blade pieces 2111, and the blade piece with larger radial dimension is closer to the bowl cover 22. Figure 3 In the shown embodiment, the stirring blade 211 comprises four blade pieces 2111, and the blade piece with larger radial dimension is also closer to the bowl cover 22.
