Description

Technical Field

[0001] This utility model relates to the field of food preparation, specifically to a food preparation machine. Background Technology

[0002] Existing food processors, such as high-speed blenders, typically have a cylindrical or regular polygonal cross-section for their cup body. This design aims to effectively break down food through the high-speed rotation of the mixing components within the cup body. The rotation axis of the mixing components is usually vertically positioned at the center of the cup body, and to enhance the blending effect, multiple vertically extending ribs are provided on the peripheral surface of the cup body.

[0003] When the mixing component rotates at high speed within the cup cavity, it generates a powerful circulating current. This current carries food particles that impact the flow ribs. The food particles impacting the ribs are then subjected to a counterforce, causing them to bounce back towards the center of the cup cavity. This allows the food particles to re-enter the working range of the mixing component, increasing the frequency of pulverization and significantly improving the cell wall breaking effect. This design, by optimizing fluid dynamics, ensures that food is processed more evenly and rapidly within the cup cavity.

[0004] However, such food processors typically produce significant vibration and noise during operation. To mitigate these issues, the weight and structural strength of the device are usually increased by enhancing the cup height and wall thickness. However, this approach may negatively impact other performance characteristics.

[0037] Example:

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, a food processor is illustrated, which mainly includes a blending cup. The blending cup includes a cup body assembly 100 and a blending component 200. The cup body assembly 100 includes a cup body forming a cup cavity, and the blending component 200 is disposed within the cup cavity and is capable of rotating about its own rotation axis, thereby driving the blades on the blending component 200 to chop or process the food in the cup cavity.

[0039] The cup body also includes a cup opening connected to the cup cavity, which is usually facing upwards and is equipped with a cup lid assembly 300 to cover the cup opening, preventing crumbs or liquids from splashing out of the cup opening when handling food, and also preventing foreign objects from falling into the cup cavity.

[0040] The cup body consists of two parts: the cup body and the bottom wall 130. The cup body is columnar or frustum-shaped, with the rim located at the top of the cup body and the bottom wall 130 located at the bottom of the cup body, forming a cavity for holding food. See also Figure 1 and Figure 2 The cup body includes a main cup shell 110 and an expansion shell 120. These two shells are positioned opposite each other and integrally connected on both sides, forming a ring structure. The main cup shell 110 and the expansion shell 120 surround the stirring assembly 200, with the rotation axis of the stirring assembly 200 located at the center of the main cup shell 110. Radially along the rotation axis of the stirring assembly 200 or radially along the cup opening, the distance from the expansion shell 120 to the rotation axis of the stirring assembly 200 is greater than the distance from the main cup shell 110 to the rotation axis, with the main cup shell 110 being closer to the rotation axis. The main cup shell 110 and the expansion shell 120 surround and connect to the outer periphery of the bottom wall 130.

[0041] The bottom wall 130 includes a connected bottom wall body 131 and a flow guide 132. The bottom wall body 131 closes the bottom opening of the main cup shell 110, and the rotation axis of the stirring assembly 200 is erected above the bottom wall body 131. The bottom of the expansion shell 120 is higher than the bottom of the main cup shell 110, and the flow guide 132 closes the bottom opening of the expansion shell 120.

[0042] Traditional mixing cups typically employ a cylindrical or regular polygonal centrally symmetrical design. This design tends to generate circulating flow within the cup cavity during operation. This circulating flow along the symmetrical inner walls can easily lead to resonance, thereby increasing equipment vibration and noise. To address this issue, traditional methods often involve increasing the cup's height and wall thickness to enhance the equipment's weight and structural strength, thus reducing vibration and noise.

[0043] To address this issue, the food processor in this embodiment employs a non-centrosymmetric structure (with the rotation axis of the mixing assembly 200 as a reference) by setting the main cup shell 110 and the expansion shell 120 at different distances from them. It should be noted that a centrosymmetric structure refers to a structure where, after rotating the cup body at a certain angle, its inner wall almost overlaps with itself. Typically, when the overlap reaches over 90% after rotation, it is considered centrosymmetric. A non-centrosymmetric structure, however, lacks this center and, regardless of rotation, can never overlap with itself. Using a non-centrosymmetric structure effectively reduces resonance and creates a more balanced noise frequency distribution, avoiding the harshness caused by excessive concentration of noise frequencies, thus allowing for a thinner cup design.

[0044] The design of the expanded shell 120 is equivalent to increasing the bottom area of ​​the cup. When the same volume of liquid is poured in, the liquid level inside the cup is correspondingly lower, improving the stability of the cup. The height of the cup can therefore be reduced accordingly, further reducing the cup wall thickness and the weight of the device. At the same time, the expanded shell 120 increases the contact area between the bottom of the cup and the tabletop, further enhancing the stability of the device and providing more design flexibility for thinning the cup wall.

[0045] Furthermore, by providing a flow guide 132 between the bottom wall body 131 and the expansion shell 120, a chamfer-like structure is formed. When the stirring assembly 200 is working, the circulating flow rises along the slope when it encounters the flow guide, carrying away large pieces of food deposited at the bottom of the cup cavity, avoiding dead zones and improving the pulverizing effect. Because the flow guide 132 is far from the rotation axis, the centrifugal force of the circulating flow is greater at this location, which can more effectively guide food fragments upward and improve stirring efficiency. In this way, vibration and noise can be effectively reduced without significantly affecting other performance characteristics.

[0046] In some embodiments, the angle between the drainage portion 132 and the bottom wall body 131 is between 105° and 165°. For example... Figure 3 As shown in the figure, an embodiment is illustrated where the angle between the flow guide 132 and the bottom wall body 131 is 150°. This angle, set near 150°, provides excellent flow guidance, effectively preventing food fragments from remaining or accumulating in the flow guide. This avoids a reduction in the pulverizing effect.

[0047] In some embodiments, the main cup shell 110 and the expansion shell 120 are integrally formed. At least one of the main cup shell 110, the expansion shell 120, and the bottom wall 130 is an alloy part with a wall thickness of 0.3mm-1mm. Specifically, the cup body and the bottom wall 130 are respectively manufactured from food-grade stainless steel sheets with a thickness of 0.3mm-1mm. The thickness of the bottom wall 130 is greater than the thickness of the cup body. The cup body and the bottom wall 130 are made of metal alloy sheets, which are easy to process and produce, and have high strength. A thinner thickness can meet the strength requirements, and the cup body can be lightweight.

[0048] In some embodiments, one of the main cup shell 110 and the expansion shell 120 is provided with flow-guiding ribs 140, the extension direction of which is the same as the axial direction of the rotation axis of the stirring assembly 200. Since the cup body is made of a metal alloy, such as food-grade stainless steel, the flow-guiding ribs 140 on its surface are easily processed by stamping. Furthermore, the fact that the flow-guiding ribs 140 extend in the same direction as the rotation axis also increases the strength of the cup body to a certain extent.

[0049] In some embodiments, a plurality of flow-encircling ribs 140 are provided on the inner wall of the cup cavity, wherein at least two flow-encircling ribs 140 are located on the main cup shell 110 and at least two flow-encircling ribs 140 are located on the expansion shell 120. The plurality of flow-encircling ribs 140 are arranged at intervals in the circumferential direction of the cup body. By providing a plurality of flow-encircling ribs 140 on the cup body, the turbulence effect on the circulating flow is increased, thereby improving the wall-breaking effect.

[0050] In some embodiments, the main cup shell 110 has a plane of symmetry, and the center position (rotation axis) of the main cup shell 110 is located on the plane of symmetry. Two flow ribs 140 located on the main cup shell 110 are respectively located on both sides of the plane of symmetry of the main cup shell 110 and are symmetrical to each other.

[0051] Specifically, the expansion shell 120 includes an arc-shaped wall 121 opposite to the main cup shell 110 and two smooth walls 122. The two smooth walls 122 are arranged opposite to each other and are respectively connected between the arc-shaped wall 121 and the main cup shell 110. See also Figure 2 The image shown is a top view of the cup body, with the main cup shell 110 and the expansion shell 120 extending vertically. The main cup shell 110 has an arc-shaped wall, and the arc range corresponding to the arc-shaped wall is... to Figure 2 The arc of the circular wall shown is π, forming a semicircular arc. Similarly, the arc-shaped wall 121 of the expansion shell 120 also adopts a semicircular arc design of π. The two smooth walls 122 are planar, and their two sides smoothly connect to one side of the arc-shaped wall 121 and one side of the main cup shell 110, respectively, to ensure that the inner surfaces of the three are smooth. The arc of the two flow ribs 140 on the main cup shell 110 is 0.5π.

[0052] In this embodiment, the expansion shell 120 includes an arc-shaped wall 121 and two smooth walls 122; the arc-shaped wall 121 is opposite to the main cup shell 110, and the cross-section of the arc-shaped wall 121 is arc-shaped; the two smooth walls 122 are arranged opposite to each other and are respectively connected between the arc-shaped wall 121 and the main cup shell 110.

[0053] Alternatively, the main cup shell 110 may have an arc-shaped wall, and the arc range corresponding to the arc-shaped wall is as follows: to The rotation axis of the stirring assembly 200 is located at the axis of the main cup shell 110.

[0054] In some embodiments, the farthest distance from the expansion shell 120 to the rotation axis of the stirring assembly 200 is 1.2 to 2 times the closest distance from the main cup shell 110 to the rotation axis. Figure 2 Viewed from above, the main cup shell 110 and the expansion shell 120 together form a racetrack-like shape. The stirring component 200 is located at the center of one of the semicircles, meaning the rotation axis is coaxial with the center of the main cup shell 110. In the figure, R is the distance from the center of the main cup shell 110 to the rotation axis, and D is the distance from the farthest point of the expansion shell 120 to the center of the rotation axis.

[0055] In some embodiments, the height of the guide portion 132 on the bottom wall body 131 is greater than the distance between the blade of the stirring assembly 200 and the bottom wall body 131. This arrangement ensures that after the rotation axis of the stirring assembly 200 rotates, the circulating force generated on the plane of rotation where the blade is located is strongest, and can act on the inclined surface of the guide portion 132, thereby improving the upward guiding effect of the inclined surface on the circulating force.

[0056] In some embodiments, the cross-sectional shape of the cup cavity is symmetrical in the radial direction along the rotation axis of the stirring assembly 200. The center of symmetry (plane) is as follows: Figures 4a-4d As shown by the dashed line at the midpoint. Figure 4a For example, the two smooth walls 122 are symmetrical about the center of symmetry, which passes through the middle of the main cup shell 110 and the arc-shaped wall 121, dividing the main cup shell 110 and the arc-shaped wall 121 into two symmetrical parts. Figure 4b and Figure 4c As shown, the cup body can also adopt a polygonal structure, as well as the arrangement of the stirring component 200 within it. Figure 4d In an alternative embodiment, a combination of polygonal and arc-shaped cups is also shown, in which the stirring assembly 200 is arranged.

[0057] In some embodiments, the main cup shell 110 and the expansion shell 120 form two opposing openings. The bottom wall 130 is hermetically connected to one of the openings, while the other opening forms the cup opening. The stirring cup also includes a lid assembly 300 that can be fitted onto the other opening.

[0058] like Figure 3 and Figure 8 As shown, in this embodiment, the cup assembly 100 further includes a housing 150 fitted over the cup body, and a handle 151 disposed on the housing 150. The housing 150 has two opposing openings, one of which connects to the opening of the cup body, with the cup body located inside the housing 150. A bottom cover is disposed on the other opening, forming a mounting cavity between the bottom cover and the bottom wall 130 of the cup body for mounting heating elements, control devices, and other equipment. The bottom wall 130 has a through hole, in which a temperature sensor is installed for temperature detection. The handle 151 is located at the main cup shell 110.

[0059] The food processor of this embodiment also includes a drive device disposed within the lid assembly 300 or at the bottom of the body assembly 100, and the rotation shaft of the mixing assembly 200 is connected to the drive device. The drive device is typically a motor. If the drive device is disposed within the lid assembly 300, the mixing assembly 200 can be detached along with the lid assembly 300. See [reference needed]. Figure 3 If the drive device is located at the bottom of the cup assembly 100, the stirring assembly 200 is fixed in the corresponding position inside the cup, and the rotating shaft passes through the bottom wall 130 of the cup bottom and is connected to the drive device for transmission. The figure shows the structure in which the drive device is located inside the cup lid assembly 300.

[0060] In some embodiments, see Figure 3 , Figure 5 , Figure 6 and Figure 7 The food processor also includes a base 500. The base 500 houses a power supply component, which can be a battery or a circuit that connects to AC power and converts the AC power into a power source for the drive unit. The blending cup is detachably connected to the base 500, with a wiring assembly at the connection point. When the blending cup is connected to the base 500, the power supply component is electrically connected to the drive unit via the wiring assembly. If the drive unit is located within the lid assembly 300, the cable of the wiring assembly can be routed through the internal cavity of the handle on the outer casing 150 and electrically connected to the lid assembly 300.

[0061] In some embodiments, see Figure 5 and Figure 8The cup lid assembly 300 includes a cup lid body 310 and a feeding cover 320. The cup lid body 310 can close to the cup mouth, and its lower surface has a lower edge around its periphery, which can be inserted into the cup mouth and fit with the inner wall of the cup mouth. A sealing ring with a sealing strip surrounds the upper outer side of the lower edge to ensure a tight connection between the lower edge and the inner wall of the cup mouth. The cup lid body 310 is provided with a feeding port 311. The feeding port 311 is located radially outside the rotating shaft of the stirring assembly 200, close to the expansion shell 120, and the feeding cover 320 is detachably installed on the feeding port 311.

Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
