Description

Technical Field

[0001] The present application relates to the technical field of small household appliances, and more specifically, to a bowl of a food processor and a food processor. Background Art

[0002] A food processor, such as a meat chopper, typically consists of a bowl and a mixing blade. Bowls with a mixing chamber are typically largest at the rim, with the dimensions gradually decreasing from the rim to the bottom, for example, in an inverted trapezoidal shape. Other bowls are generally straight, with the same dimensions from the rim to the bottom. With these two bowl shapes, when the mixing blades are used to blend ingredients, the ingredients can easily splash toward the rim due to the stirring. Summary of the Invention

[0003] The present application provides a food processor bowl and a food processor, which can reduce the splashing of food toward the mouth of the bowl.

[0004] A bowl body of a food processor comprises a bowl body and a stirring blade rotatably arranged in the bowl body.

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

[0006] The bowl body includes a bowl bottom located at the bottom, an outward-expanding section gradually extending upward and outward from the bowl bottom, and an inward-retracting section gradually extending upward and inward from the outward-expanding section. The top of the inward-retracting section is higher than the highest blade on the knife shaft, and the height difference is set to 10mm to 70mm.

[0007] The bowl body provided by the present application has a gradually decreasing diameter from the junction of the outward-expanding section and the inward-retracting section. When the mixing blade is in operation, the food adheres to the inner wall of the bowl body under the stirring action of the mixing blade and gradually flows from the bottom of the bowl to the rim. When the food passes the junction of the outward-expanding section and the inward-retracting section, the inward-retracting section retracts, and at least part of the food's own weight overcomes the adhesion between the food and the inner wall of the bowl body. This part of the food falls from the inner wall of the bowl body and falls back into the mixing chamber. This allows the fallen food to be repeatedly stirred and also reduces the food from flowing out of the bowl rim. In addition, the top of the inward-retracting section is set higher than the highest blade on the blade shaft, which helps more food fall back into the mixing chamber after passing through the junction P, increasing the chance of the food being repeatedly stirred. The height difference H is 10mm to 70mm, which can not only reduce the food from flying out of the bowl rim during the stirring process, but also reduce the accumulation of food in the inward-retracting section.

[0008] Optionally, the bowl body has a maximum diameter at the junction of the outward-expanding section and the inward-retracting section, and the difference between the maximum diameter and the diameter of the top of the inward-retracting section is 5 to 15 mm. This configuration can limit the slope or curvature of the inward-retracting section when it contracts inward, making the slope or curvature of the inward-retracting section more appropriate.

[0009] Optionally, the blades are provided in multiple locations, one of which is a first blade located at the highest point of the blade shaft. Along the axis 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 arrangement can limit the position of the first blade relative to the bowl body, preventing the first blade from being positioned too high, thereby reducing the chance of ingredients splashing out of the bowl mouth during blending, and also preventing the first blade from being positioned too low, thereby reducing the mixing space.

[0010] Optionally, the bowl body further comprises a bowl opening at the top, and the top end of the retracted section forms the bowl opening. This arrangement can make the shape of the bowl body more concise and less difficult to manufacture.

[0011] Optionally, the bowl body further comprises a bowl opening at the top, and the bowl body further comprises an extension section extending upward from the top end of the retracted section, the top end of the extension section forming the bowl opening. The extension section realizes a transition between the retracted section and the bowl opening, facilitating the positioning and matching of the bowl body and the bowl lid.

[0012] Optionally, the extension section is an annular straight tube structure, which is simple in structure and easy to process.

[0013] Optionally, the extension section is a non-straight cylindrical structure that is larger at the top and smaller at the bottom. This structure can provide support for the bowl cover.

[0014] Optionally, the bowl body further includes a spoiler rib protruding from the inner wall. The spoiler rib extends upward from the bottom of the bowl, passing through the junction of the outward-expanding section and the inward-retracting section. Below the junction, the end surface of the spoiler rib in the protruding direction gradually extends upward and outward, and above the junction, the end surface gradually extends upward and inward. This allows food adhering to the spoiler rib to fall off as the end surface of the spoiler rib gradually bends toward the blade shaft, facilitating repeated blending of the food.

[0015] Optionally, the blades are provided in plurality, at least one of which is a second blade positioned higher than the lower end of the spoiler rib and lower than the upper end of the spoiler rib, with a gap of 2 to 10 mm between the tip of the second blade and the end surface along the radial direction of the blade axis. This arrangement can reduce the gap between the blade and the spoiler rib, increase the stirring radius, and improve the whipping efficiency.

[0016] Optionally, a gap of 2 to 10 mm is provided between the tip of at least one of the blades and the inner wall of the bowl body along the radial direction of the blade axis. This arrangement can reduce the gap between the blade and the inner wall of the bowl body, thereby increasing the stirring space and improving the whipping efficiency.

In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0027] Please refer to Figure 1 , Figure 1 Schematic diagram of a food processor 100 according to an exemplary embodiment of the present application.

[0028] The present application provides a food processor 100, which includes a main unit 10 and a bowl 20, wherein the main unit 10 is detachably connected to the bowl 20. The main unit 10 can be configured as a head-type main unit, and the main unit 10 is installed above the bowl 20.

[0029] Please refer to Figure 2 , Figure 2 It is a cross-sectional view of a bowl body 20 shown in an exemplary embodiment of the present application.

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

[0031] The mixing blade 22 comprises a blade shaft 220 and a blade 221 mounted on the blade shaft 220. One or more blades 221 may be provided, and multiple blades 221 may be positioned 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, thereby driving the mixing blade 22. A bowl shaft 24 may also be provided at the bottom of the bowl body 21. The bowl shaft 24 is coaxial with the blade shaft 220 and engages with a hole at the bottom of the blade shaft 220 to reduce the amount of shaking of the mixing blade 22 during rotation.

[0032] The bowl body 21 further includes a bowl bottom 211, a bowl rim 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 is shaped to be stably supported on a tabletop, including but not limited to a flat bowl bottom 211. The bowl rim 212 is located at the top of the bowl body 21, forming the mouth of the bowl body 21. The mixing blade 22 can be inserted into the mixing chamber 210 through the bowl rim 212, and ingredients can also be placed into the mixing chamber 210 through the bowl rim 212.

[0033] The flared section 213 gradually extends upward and outward from the bowl bottom 211. That is, the diameter of the flared section 213 gradually increases from bottom to top. In one embodiment, a longitudinal section through the axis of the cutter shaft cuts the flared section 213, resulting in a straight, oblique section extending upward and outward. In another embodiment, a longitudinal section through the axis of the cutter shaft cuts the flared section 213, resulting in an arc-shaped section extending upward and outward.

[0034] The inward section 214 is connected to the top of the outward section 213, and gradually extends upward and inward from the outward section 213, that is, the diameter of the inward section 214 gradually decreases from bottom to top. In one embodiment, the inward section 214 is cut with a longitudinal section passing through the axis of the blade shaft, and the section is an oblique and straight section extending upward and inward. In another embodiment, the inward section 214 is cut with a longitudinal section passing through the axis of the blade shaft, and the section is an arc-shaped section extending upward and inward. The space enclosed by the outward section 213 and the inward section 214 is the stirring chamber 210. The top 2140 of the inward section 214 is higher than the highest blade on the blade shaft 220, and the height difference H is 30 mm to 50 mm. The bowl mouth 212 can be formed at the top 2140 of the inward section 214, but is not limited to this.

[0035] According to the above description, it can be seen that the diameter of the bowl body 21 gradually decreases from the junction P of the outward-expanding section 213 and the inward-retracting section 214. When the mixing blade 22 is working, the food adheres to the inner wall of the bowl body 21 under the stirring action of the mixing blade 22, and gradually flows from the bottom 211 of the bowl to the bowl mouth 212. After the food passes through the junction P of the outward-expanding section 213 and the inward-retracting section 214, due to the inward retraction of the inward-retracting section 214, at least part of the food's own weight will overcome the adhesion force between itself and the inner wall of the bowl body 21, and this part of the food will fall from the inner wall of the bowl body 21 and fall back into the stirring chamber 210. In this way, the fallen food can be repeatedly stirred, and the food can also be reduced from flowing out of the bowl mouth 212.

[0036] When whipping, the blade 221 causes the ingredients to flip and flow toward the bowl rim 212. In this application, the top 2140 of the retracted section 214 is set higher than the highest point of the blade 221 on the blade shaft 220. This helps more ingredients fall back into the mixing chamber 210 after passing through the connection point P, increasing the chance of the ingredients being whipped repeatedly. The height difference H between the top 2140 and the highest point of the blade 221 is 10mm to 70mm. If the height difference H is too small, the ingredients can easily fly out of the bowl rim 212 during whipping. If the height difference H is too large, the ingredients may accumulate on the top of the retracted section 214. The height difference H can be set to 10mm, 20mm, 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 44mm, 46mm, 48mm, 50mm, 55mm, 60mm, 65mm, or 70mm.

[0037] exist Figure 2 In the illustrated embodiment, the cutter shaft 220 is provided with a plurality of blades 221 , which are spaced apart along the axial direction of the cutter shaft, wherein the height of the joint portion P is higher than the heights of all the blades 221 .

[0038] In one embodiment, the bowl body 21 has a maximum diameter B at the junction P between the outward-expanding section 213 and the inward-retracting section 214. The difference between the maximum diameter B and the diameter A of the top 2140 of the inward-retracting section 214 is 5 to 15 mm. This configuration can limit the slope or curvature of the inward-retracting section 214 as it contracts inward. If the difference in diameter between the two is small, the slope of the inward-retracting section 214 is too small, reducing the effect of food turning over and falling at the junction P. If the difference in diameter between the two is large, the slope of the inward-retracting section 214 is too large, causing food to accumulate in the inward-retracting section 214. When the diameter difference is 5 to 15 mm, the slope or curvature of the inward-retracting section 214 is more appropriate.

[0039] In a specific embodiment, the difference between the maximum diameter 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 thereto.

[0040] In one embodiment, the blades 221 are provided in plurality, 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 5 mm. In other words, the first blade 221a can be within 5 mm higher than the maximum diameter of the bowl body 21, or it can be within 5 mm lower than the maximum diameter of the bowl body 21. With such a setting, the position of the first blade 221a relative to the bowl body 21 can be limited, avoiding the first blade 221a from being too high, reducing the probability of ingredients splashing out of the bowl mouth 212 during beating, and avoiding the first blade 221a from being too low to reduce the mixing space. It should be noted that the maximum diameter can be set at 1 / 2 of the height of the bowl body 21, but is not limited to this.

[0041] In one embodiment, a gap of 2 to 10 mm is provided between the tip of at least one blade 221 and the inner wall of the bowl body 21 along the radial direction of the blade axis. This arrangement reduces the gap C between the blade 221 and the inner wall of the bowl body 21, increases the stirring radius, and improves whipping efficiency. Examples of the gap C include 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm.

[0042] exist Figure 2 In the embodiment shown, a plurality of blades 221 are provided, one of the plurality of blades 221 is closest to the bowl bottom 211, and a gap of 2 to 10 mm is provided between the blade 221 closest to the bowl bottom 211 and the inner wall of the bowl body 21 along the radial direction of the blade axis. In this way, more food at the bowl bottom 211 can be stirred and flipped by the blade 221, and the food can be more easily crushed.

[0043] In one embodiment, Figure 2 As shown, the bowl body 21 further includes spoiler ribs 2110 protruding from the inner wall. The spoiler ribs 2110 extend from the bowl bottom 211 toward the bowl rim 212, with the bottom end higher than the bowl bottom 211 and the top end lower than the bowl rim 212. The specific number of spoiler ribs 2110 is not limited. For example, multiple spoiler ribs 2110 can be provided at intervals to improve the whipping effect.

[0044] The spoiler rib 2110 passes through the junction of the outward-expanding section 213 and the inward-retracting section 214. Below the junction P, the end surface 2110a of the spoiler rib 2110 at the end in the protruding direction gradually extends upward and outward. Above the junction P, the end surface 2110a gradually extends upward and inward. The end surface 2110a is the end surface of the spoiler rib 2110 facing the blade shaft 220. This end surface 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 bowl bottom 211 to the bowl rim 212, the direction of this end surface 2110a is the same as the direction of the outer contour surfaces of the outward-expanding section 213 and the inward-retracting section 214. This allows food adhering to the spoiler rib 2110 to fall off as the end surface 2110a of the spoiler rib 2110 gradually bends toward the blade shaft 220, facilitating repeated blending of the food.

[0045] In one embodiment, Figure 2 As shown, the blades 221 are provided with multiple blades, at least one of which is a second blade 221b that is higher than the lower end of the spoiler rib 2110 and lower than the upper end of the spoiler rib 2110. A gap of 2 to 10 mm is provided between the tip of the second blade 221b and the end surface 2110a along the blade axis radial direction. 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 arrangement can reduce the gap between the blades 221 and the spoiler rib 2110, thereby increasing the stirring space and improving the whipping efficiency.

[0046] exist Figure 2 In the illustrated embodiment, four blades 221 are provided. The four blades 221 are arranged from high to low on the blade shaft 220. The first blade 221a, located at the highest point, and the second blade 221b, which is second only to the first blade 221a in height, are respectively positioned between the two ends of the spoiler rib 2110. A gap of 2 to 10 mm is provided between the two blades 221 and the end surface 2110a along the radial direction of the blade shaft. The first blade 221a and the second blade 221b can be spaced 180 degrees apart, but this is not limited to this.

[0047] In one embodiment, Figure 2 As shown, the bowl body 21 further includes an extension section 216 extending upward from the top end 2140 of the retracted section 214, and the top end of the extension section 216 forms the bowl mouth 212 of the bowl body 21. The extension section 216 realizes the transition between the retracted section 214 and the bowl mouth 212, facilitating the positioning and matching of the bowl body 20 and the bowl cover 23.

[0048] In a specific embodiment, the extension section 216 is an annular straight tube structure or a non-straight tube structure with a larger top and a smaller bottom. Figure 2 In the illustrated embodiment, the extension section 216 is an annular straight cylindrical structure, which is simple in structure and easy to process.

[0049] Please refer to Figure 3 , Figure 3 It is a cross-sectional view of another embodiment of a bowl body.

[0050] In one embodiment, Figure 3 As shown, the extension section 216 is stepped and includes a tapered end 2160 connected to the inward section 214 and a straight section 2161 connected above the tapered end 2160. The small end of the tapered end 2160 connects to the inward section 214, while the large end of the tapered end 2160 connects to the straight section 2161. This structure provides support for the bowl cover 23. The extension section 216 can be configured to meet specific needs, for example, to accommodate bowl covers 23 of different shapes.

[0051] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 It is a cross-sectional view of another embodiment of the bowl body 20.

[0052] exist Figure 4 and Figure 5 In the embodiment shown, the top end 2140 of the retracted section 214 forms the bowl mouth 212. This arrangement can make the bowl body 20 more compact in appearance and less difficult to manufacture.

[0053] exist Figure 4 In the example shown, the outward-expanding section 213 and the inward-retracting section 214 are symmetrical about the midline at 1 / 2 of the height of the bowl body 21 , and the shape is more uniform.

[0054] exist Figure 5 In the example shown, the radius of curvature of at least a portion of the flared section 213 is smaller than the radius of curvature of the retracted section 214. Figure 5 In the example shown, the outward expansion section 213 includes a first outward expansion section 2130 connected to the bowl bottom 211 and a second outward expansion section 2131 connected to the inward expansion section 214 . The curvature radius of the first outward expansion section 2130 is smaller than the curvature radius of the second outward expansion section 2131 .

[0055] In one embodiment, the bowl body 21 can be formed in one piece, including but not limited to casting. The outward-flaring section 213 and the inward-flaring section 214 together form the side of the bowl body 21. This side can be configured as a portion of an arc or a portion of a sphere about the axis of the blade shaft. In other words, the smooth transition between the outward-flaring section 213 and the inward-flaring section 214 ensures a smooth transition on the inner wall of the side, making it easier for food adhering to the inner wall to fall off.

[0056] exist Figures 2 to 5In the illustrated embodiment, an annular flange 217 is further provided on the top of the bowl body 21 . The annular flange 217 can be used to support the bowl cover and is also convenient for taking the bowl body 20 .

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
