Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a liquid trapping device and a cooking pot. Background Technology
[0002] Consumers are increasingly demanding higher quality rice, with a sweet and fragrant taste being a primary requirement. The perceived sweetness of rice stems from the fact that, as a starch-based food, the starch undergoes thermal degradation during cooking, producing smaller sugar molecules. Furthermore, during chewing, the presence of salivary amylase and other enzymes further breaks it down into smaller sugar molecules like maltose, all contributing to the perceived sweetness. However, cooking appliances like rice cookers often result in significant loss of the sweet components dissolved in starchy foods due to Maillard reactions, leading to insufficient sweetness after cooking.

[0033] like Figures 1 to 4 As shown, this utility model provides a liquid trapping device 10 for installation inside a pot body 20. The liquid trapping device 10 includes a trapping component body 110. The surface of the trapping component body 110 has a trapping groove 111, and a liquid inlet hole 112 and a return flow hole 113 communicating with the trapping groove 111. The liquid inlet hole 112 allows liquid from the pot body 20 to enter the trapping groove 111, and the return flow hole 113 allows liquid from the trapping groove 111 to flow back to the pot body 20. The distance between the surface of the trapping component body 110 and the plane containing the pot opening of the pot body 20 has a height difference.
[0034] Figure 5 It shows Figure 1 A magnified view of a portion of point A in the diagram. Figure 6 It shows Figure 3 The diagram shows a magnified view of part B in the middle. Arrows indicate virtual objects such as through holes and spaces, while objects without arrows are solid objects.
[0035] like Figure 5 and Figure 6 As shown, in some embodiments, the intercepting component body 110 includes a first region 1141 and a second region 1142, wherein the distance between the first region 1141 and the opening of the intercepting groove 111 is less than the distance between the second region 1142 and the opening of the intercepting groove 111. A liquid inlet hole 112 is located in the first region 1141; a return flow hole 113 is located in the second region 1142, such that along the vertical direction of the pot body 20, the height of the first region 1141 is higher than the height of the second region 1142, allowing the liquid in the intercepting groove 111 to flow towards the second region 1142 where the return flow hole 113 is located, facilitating the outflow of liquid from the intercepting groove 111 through the return flow hole 113.
[0036] In some embodiments, the distance between the lowest surface of the first region 1141 and the plane where the pot opening of the pot body 20 is located is less than the distance between the lowest surface of the second region 1142 and the plane where the pot opening of the pot body 20 is located.
[0037] In some embodiments, the interceptor body 110 includes a bottom wall region 114 and a side blocking region 115, and the interception groove 111 is defined by the bottom wall region 114 and the side blocking region 115. The first region 1141 and the second region 1142 are both located in the bottom wall region 114 of the interceptor body 110.
[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the second region 1142 is located in the central region of the bottom wall region 114, and the first region 1141 is arranged around the periphery of the second region 1142. That is, the return flow hole 113 is located in the central region of the bottom wall region 114 of the interceptor body 110, and the liquid inlet hole 112 is located in the peripheral region of the interceptor body 110. This allows the liquid in the pot body 20 to enter the interception tank 111 from the outer peripheral region and then flow back into the pot body 20 from the central region.
[0039] like Figure 3 and Figure 4 As shown, in some other embodiments, the first region 1141 is located in the middle of the bottom wall region 114, and the second region 1142 is arranged around the first region 1141. That is, the liquid inlet hole 112 is located in the middle of the bottom wall region 114 of the interceptor body 110, so that the liquid in the pot 20 can enter the interceptor tank 111 from the middle and then flow back into the pot 20 from the outer peripheral region.
[0040] In some embodiments, along the vertical direction of the pot body 20, the height of the side of the first region 1141 closer to the second region 1142 is lower than the height of the side away from the second region 1142, so that when the retainer body 110 is used in the pot body 20, the surface of the first region 1141 is inclined at a certain angle relative to the horizontal, and the height of the side closer to the second region 1142 is lower, so that the liquid in the retainer tank 111 can flow from the first region 1141 to the second region 1142.
[0041] In some embodiments, along the vertical direction of the pot body 20, the height of the side of the second region 1142 closer to the first region 1141 is higher than the height of the side farther from the first region 1141, so that when the retainer body 110 is used in the pot body 20, the surface of the second region 1142 is inclined at a certain angle relative to the horizontal, and the height of the side closer to the first region 1141 is higher, so that the liquid in the retaining groove 111 can flow in the second region 1142 to flow to the return flow hole 113.
[0042] In some embodiments, the liquid inlet holes 112 include a plurality of holes, which are spaced apart in the first region 1141, and liquid can be collected quickly through the plurality of liquid inlet holes 112 spaced apart in the first region 1141. When the first region 1141 is arranged around the periphery of the second region 1142, the plurality of liquid inlet holes 112 are distributed around the periphery of the return flow hole 113.
[0043] In some embodiments, the area of the liquid inlet hole 112 is larger than the area of the return flow hole 113, which allows the liquid in the pot body 20 to enter the interception tank 111 through the liquid inlet hole 112.
[0044] like Figure 2 and Figure 4 As shown, the bottom wall region 114 can be a cross-section of the space inside the pot body 20 (a cross-section along the horizontal direction of the pot body 20). Figure 1 and Figure 3 The X-axis direction is a circle adapted along the horizontal direction of the pot body 20. In some embodiments, such as Figure 2 As shown, the first region 1141 is an annular region, and the various liquid inlet holes 112 are distributed at intervals within this annular region. In other embodiments, such as Figure 4 As shown, the first region 1141 is a circular region, and each liquid inlet hole 113 is distributed at intervals within this circular region.
[0045] In some embodiments, the return flow holes 113 include a plurality of holes, which are spaced apart in the second region 1142, so that the liquid in the trap 111 can flow back to different parts of the pot body 20 to mix more evenly with the food in the pot body 20.
[0046] In some embodiments, the area of the return flow hole 113 located near the center of the interceptor body 110 is larger than the area of the return flow hole 113 located away from the geometric center of the interceptor body 110, thereby enabling the liquid to carry more heat to the central region inside the pot body 20, which is beneficial to the uniformity of heat inside the pot body 20.
[0047] like Figure 5 and Figure 6 As shown, in some embodiments, the liquid interception device 10 further includes a first flow-blocking rib 120, which protrudes from the interception body 110 toward the interception groove 111 to prevent liquid in the interception groove 111 from flowing back through the liquid inlet hole 112. It can be understood that along the vertical direction of the pot body 20 ( Figure 1 and Figure 3 (The Y-axis direction is the vertical direction of the pot body 20, and the X-axis direction is the horizontal direction of the pot body 20). The surface of the first flow-blocking rib 120 needs to be lower than the opening of the interception groove 111.
[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the first flow-blocking rib 120 is integrally formed with the intercepting member body 110. That is, the first flow-blocking rib 120 is a local area of the intercepting member body 110 that protrudes towards the intercepting groove 111. The liquid inlet hole 112 is located at the protruding part of the first flow-blocking rib 120 to prevent the liquid in the intercepting groove 111 from flowing back from the liquid inlet hole 112.
[0049] In some embodiments, the first region 1141 has a plurality of protruding regions that protrude toward the interception groove 111 and are spaced apart. Each protruding region may be circular or other shapes. A liquid inlet hole 112 is provided in each protruding region toward the interception groove 111, and each protruding region protruding toward the interception groove 111 is a first flow-blocking rib 120.
[0050] In other embodiments, the first region 1141 has an annular protruding region that protrudes toward the interception groove 111 and surrounds the center of the bottom wall region 141, and a plurality of liquid inlet holes 112 are provided at intervals in the annular protruding region.
[0051] In other embodiments, the first flow-blocking rib 120 is independent of the intercepting member body 110 and is disposed on the surface of the intercepting member body 110. The surface of the first flow-blocking rib 120 is higher than the surface of the liquid inlet hole 112, and the first flow-blocking rib 120 is disposed around the outer peripheral area of the liquid inlet hole 112 to prevent the liquid in the intercepting groove 111 from flowing back from the liquid inlet hole 112.
[0052] Figure 7 It shows Figure 1 A schematic diagram showing the liquid trapping device installed in the partitioned space inside the reactor vessel. (See diagram.) Figure 7 As shown, in some embodiments, the interceptor body 110 is adapted to the space inside the pot body 20. When the liquid interception device 10 is installed inside the pot body 20, it is used to divide the space inside the pot body 20 into a first space 210 and a second space 220. The first space 210 is close to the pot opening of the pot body 20, and the interception groove 111 is located in the first space 210. The groove opening of the interception groove 111 is opposite to the pot opening of the pot body 20.
[0053] In some embodiments, the liquid trapping device 10 further includes a third flow-blocking rib (not shown), which is disposed between the first region 1141 and the second region 1142. The third flow-blocking rib separates the bottom wall region 114 of the trapping member body 110 into the first region 1141 and the second region 1142. The third flow-blocking rib protrudes from the trapping member body 110 toward the trapping groove 111, which can slow down the flow of liquid in the trapping groove 111, thereby increasing the residence time of liquid in the trapping groove 111 and further improving the sweetness of starchy foods after cooking.
[0054] In some embodiments, the third flow-blocking rib is integrally formed with the intercepting member body 110, that is, the third flow-blocking rib is formed by a local area of the intercepting member body 110 protruding towards the intercepting groove 111. In other embodiments, the third flow-blocking rib is fixed independently to the surface of the intercepting member body 110 relative to the intercepting member body 110.
[0055] In some embodiments, the second region 1142 includes multiple sub-regions at different distances from the first region 1141. The distance between the sub-regions farther from the first region 1141 and the opening of the trap 111 is greater than the distance between the sub-regions closer to the first region 1141 and the opening of the trap 111. Multiple return flow holes 113 are provided at intervals in each sub-region so that liquid can flow sequentially between the sub-regions and so that the liquid entering the trap 111 flows to each return flow hole 113.
[0056] In some embodiments, each sub-region of the second region 1142 is an annular region arranged sequentially around the periphery of the first region 1141 and at different distances from the first region 1141. In other embodiments, each sub-region of the second region 1142 includes a circular sub-region located at the center of the interceptor body 110, and the remaining sub-regions are annular sub-regions arranged sequentially around the circular sub-region.
[0057] In some embodiments, along the vertical direction of the pot body 20, the height of the side of each sub-region closer to the first region 1141 is higher than the height of the side away from the first region 1141, so that when the liquid trapping device 10 is installed in the pot body 20 for use, the surface of each sub-region is inclined at a certain angle relative to the horizontal, and the height of the side closer to the first region 1141 is higher, which is beneficial to the flow of liquid in the trapping tank 111 in each sub-region.
[0058] In some embodiments, a second flow-blocking rib 130 is provided between two adjacent sub-regions, and the second flow-blocking rib 130 protrudes from the intercepting member body 110 toward the intercepting groove 111. The second flow-blocking rib 130 includes one or more, and each second flow-blocking rib 130 separates two adjacent sub-regions.
[0059] Understandably, the distance between the second flow-blocking rib 130 and the opening of the interception tank 111 is less than the distance between the first flow-blocking rib 120 and the opening of the interception tank 111, so that the liquid in the interception tank 111 can flow to the next sub-region. In the case of multiple second flow-blocking ribs 130, the distance between the second flow-blocking rib 130 closer to the first region 1141 and the opening of the interception tank 111 is less than the distance between the second flow-blocking rib 130 farther from the first region 1141 and the opening of the interception tank 111, so that the liquid in the interception tank 111 can flow to the next sub-region.
[0060] like Figure 5 and Figure 6 As shown, in some embodiments, the second flow-blocking rib 130 is integrally formed with the intercepting member body 110, that is, a local area of the surface of the intercepting member body 110 protrudes towards the intercepting groove 111 to form the second flow-blocking rib 130. A second flow-blocking rib 130 can be provided between every two adjacent sub-regions. The second flow-blocking rib 130 is an annular protruding area protruding from the surface of the intercepting member body 110 towards the intercepting groove 111 and surrounding the geometric center of the bottom wall region 1141, thereby separating two adjacent sub-regions.
[0061] In other embodiments, the second flow-blocking rib 130 is independent of the interceptor body 110 and fixed to the surface of the interceptor body 110, and can also separate two adjacent sub-regions.
[0062] In some embodiments, the interceptor body 110 further includes a support region 116 for supporting the interceptor body 110 so that the support interceptor body 110 is disposed within the pot body 20.
[0063] It is understood that the support area 116 can be the edge area of the intercepting part body 110. The edge area is bent away from the intercepting groove 111 relative to the side guard area 115, and can support the intercepting part body 110 in the pot body 20.
[0064] The liquid trapping device 10 provided in one or more embodiments of this utility model is used inside the pot body 20. During the cooking process of a mixture of starchy ingredients and liquid in the pot body 20, the liquid containing sweet components dissolved in the pot body 20 can enter the trapping tank 111 from the liquid inlet hole 112 under boiling action, and then flow back into the pot body 20 from the return flow hole 113. This prevents the liquid containing sweet components from being continuously boiled and heated in the pot body 20, thereby reducing the loss of sweet components due to the Maillard reaction during the boiling process in the pot body 20, and thus improving the sweetness of the cooked starchy ingredients. The trapping device body 110 can break bubbles when the liquid enters the trapping tank 111 in the pot body 20, preventing the liquid from overflowing during boiling, allowing the pot body 20 to boil to a greater extent, and improving the taste of cooked starchy ingredients such as rice.
[0065] Based on the same technical concept, this utility model also provides a cooking pot. For example... Figure 7 As shown, the cooking pot includes a pot body 20 and a liquid trapping device 10. The liquid trapping device 10 is disposed inside the pot body 20 and is used to divide the space inside the pot body 20 into a first space 210 and a second space 220. The first space 210 is closer to the rim of the pot body 20 than the second space. A trapping groove 111 is located in the first space 210, and the second space 220 is used to hold food ingredients, such as a mixture of starchy ingredients and liquid.
[0066] In some embodiments, a support step 230 is provided at the rim of the pot body 20, and the support area 116 of the retaining member body 110 rests on the surface of the support step 230 of the pot body 20. In other embodiments, the cooking cookware also includes a lid (not shown), and the support area 116 of the retaining member body 110 is fixed to the lid.
[0067] Although some embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make further changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0068] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
