Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking utensils technology, and in particular to a pot lid and a cooking utensil. Background Technology
[0002] In existing cooking appliances, such as small-capacity rice cookers, the inner lid is flat. In addition, the rice cooker's sensor is placed in the middle of the inner pot, and the heating plate is placed on the edge of the inner pot. For the entire heating plate, the edge of the heating area has a high temperature, while the center has a low temperature because there is no heating plate. When cooking, the rice water boils and rolls towards the center. Due to this characteristic, the condensation water accumulated on the traditional flat inner lid will fall directly to the cold center of the rice, resulting in the rice being dry and hard at the edges and soft and mushy in the center. Utility Model Content
[0003] The main purpose of this utility model is to propose a pot lid and cooking utensil to solve the problem of uneven heating causing rice to be dry and hard at the edges and soft and mushy in the center.
[0004] To achieve the above objectives, this utility model proposes a pot lid for use in cooking appliances. The pot lid includes an inner lid, which is a hemispherical shape that convexes upwards. The inner lid is provided with a guide portion that extends from the top of the inner lid to its edge. The top of the guide portion is a flat surface, and the edge of the flat surface to the edge of the inner lid is an arc surface. Condensed water collects on the flat surface and flows along the arc surface to the edge of the inner lid.
[0005] In one embodiment, the cooking appliance includes an inner pot, with an inner lid mounted above the inner pot, and the height ratio of the inner lid to the inner pot is in the range of 1:2 to 1:4.
[0006] In one embodiment, the guide section includes a collection area, a diversion area, and a dissipation area connected in sequence. Water vapor accumulates in the collection area to form condensate, and the condensate flows from the collection area through the diversion area and the dissipation area to the edge of the inner cover.
[0007] In one embodiment, the flow guiding portion includes flow guiding peaks and flow guiding valleys spaced apart, and both the flow guiding peaks and the flow guiding valleys radiate outwards from the top center of the inner cover towards the edge of the inner cover.
[0008] In one embodiment, the aggregation region is distributed within the plane and the arc surface, and the height of the guiding peak in the aggregation region is flush with the height of the guiding valley.
[0009] In one embodiment, the drainage area is distributed within the arc surface, and the height of the guiding peak in the drainage area gradually rises from the junction of the gathering area and the drainage area to the middle of the inner cover. The drainage area is used to increase the surface tension of the condensate.
[0010] In one embodiment, the dissipation zone is distributed within the arc surface, and the height of the guide peak in the dissipation zone gradually decreases from the middle of the inner cover to be level with the height of the guide valley.
[0011] In one embodiment, the top of the inner cover is provided with a cover stem and an installation opening, the cover stem is fitted with the installation opening, the inner side of the installation opening is provided with an installation part, the cover stem is provided with an installation groove, and the installation part is embedded in the installation groove.
[0012] In one embodiment, the upper end of the cap is provided with a handle, which is cylindrical in shape with a larger top and a smaller bottom, and the lower end of the cap is provided with a carrying handle, the two sides of which are concave.
[0013] In one embodiment, the edge of the inner cover is provided with an annular seal, which is used to seal the inner cover and the inner pot.
[0014] In one embodiment, the sealing element is provided with a positioning part, the edge of the inner cover extends into a platform, the platform is provided with a first positioning port, the edge of the inner pot is provided with a second positioning port, and the positioning part cooperates with the first positioning port and the second positioning port respectively.
[0015] In one embodiment, the inner lid is provided with a steam vent, and the pot lid is provided with a silicone component. When the pot lid is closed, the silicone component connects with the steam vent to form a steam venting channel.
[0016] This utility model also proposes a cooking appliance, which is an electric rice cooker, and the cooking appliance includes the lid.
[0017] This invention uses an inner lid with an upwardly convex hemispherical shape to guide the accumulated condensate to the edge of the inner lid, preventing the food inside the cookware from becoming dry and hard at the edges and soft and mushy in the center. The condensate will collect on the flat surface and flow along the curved surface to the edge of the inner lid, and finally flow along the inner surface of the inner pot into the hotter, drier edge area of the rice. This allows the moisture and temperature inside the inner pot to reach a balanced state, resulting in more even moisture distribution in the rice. Instead of the rice being dry and hard at the edges and soft and mushy in the center, the rice grains in the inner pot are distinct and have a moderately firm texture. Attached Figure Description

[0032] A pot lid 2 is applied to a cooking utensil 1. The pot lid 2 includes an inner lid 21, which is a hemispherical shape that convexes upward. The inner lid 21 is provided with a guide portion 211 distributed from the top of the inner lid 21 to the edge of the inner lid 21. The top of the guide portion 211 is a plane 2113, and the edge of the plane 2113 to the edge of the inner lid 21 is an arc surface 2114. Condensed water collects on the plane 2113 and flows along the arc surface 2114 to the edge of the inner lid 21.
[0033] In the embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 5 As shown, Figure 1 This is a partial structural diagram of cooking utensil 1. Figure 2 This is a schematic diagram of the inner lid 21 and the inner pot 11. Figure 5 This is a cross-sectional view of the inner lid 21. Since the temperature sensor 4 of the cooking appliance 1 is located in the middle of the bottom of the inner pot 11, and the heating plate 3 of the cooking appliance 1 is placed at the edge of the bottom of the inner pot 11, the edge of the heating area of the heating plate 3 has a high temperature, while the center of the bottom of the inner pot 11 has a low temperature because there is no heating plate 3. During cooking, the rice soup inside the pot boils and simmers towards the center. Figure 4As indicated by the rolling direction D of the rice water, by setting an inner lid 21 with an upwardly convex hemispherical shape on the lid 2, the accumulated condensate is guided to the edge of the inner lid 21 to prevent the food in the cooking appliance 1 from being dry and hard at the edges and soft and mushy in the center. The condensate collects on the plane 2113 and flows along the arc surface 2114 to the edge of the inner lid 21, and finally flows along the inner surface of the inner pot 11 into the hotter, drier edge area of the rice. This makes the moisture and temperature inside the inner pot 11 coordinate and reach a balanced state, so that the overall moisture of the rice is more uniform and there is no state of dry and hard edges and soft and mushy in the center. Instead, the rice grains in the inner pot 11 are distinct and of moderate softness.
[0034] like Figure 5 As shown, the inner cover 21 is a hemispherical shape with an upward convexity. The hemispherical inner cover 21 improves the problems of small effective diameter, short height and small volume of traditional small-capacity cooking appliances 1. It eliminates the problem of not being able to close the lid after putting in tall ingredients such as steamed buns, eggs, and corn. It can realize simultaneous cooking and steaming. The hemispherical design of the inner cover 21 can expand the capacity of the cooking appliance 1 cavity, making the overall cooking and heating cavity approximately spherical, solving the pain point of not being able to steam food at the same time when cooking rice, and increasing the practicality of the cooking appliance 1. In addition, the material of the inner cover 21 can be metal, glass, ceramic, etc., and the material of the inner cover 21 can be selected according to the actual situation.
[0035] First specific embodiment
[0036] like Figure 7 As shown, Figure 7 This is a schematic diagram of the inner lid 21 and the inner pot 11. The cooking appliance 1 includes an inner pot 11, and the inner lid 21 is installed above the inner pot 11. The height ratio of the inner lid 21 to the inner pot 11 ranges from 1:2 to 1:4. The reasonable design of the height F of the inner lid 21 and the height G of the inner pot 11 effectively prevents foam or liquid from overflowing during cooking due to high temperature and pressure. The slightly higher design of the inner lid 21 can accommodate certain pressure fluctuations and overflows, preventing liquid from spilling out of the pot and keeping the kitchen clean. In a pressure cooker, the circulation of steam and the distribution of heat are crucial. The height ratio of the inner lid 21 to the inner pot 11 helps maintain a balanced steam circulation within the pot, ensuring that the food is heated evenly while maintaining optimal cooking pressure.
[0037] Second specific embodiment
[0038] like Figure 3 As shown, Figure 3The diagram shows the distribution of the gathering area A, the diversion area B, and the dissipation area C. The guide section 211 includes the gathering area A, the diversion area B, and the dissipation area C connected in sequence. Water vapor gathers in the gathering area A to form condensate. The condensate flows from the gathering area A through the diversion area B and the dissipation area C to the edge of the inner cover 21.
[0039] The flow guiding section 211 includes spaced-apart flow guiding peaks 2111 and flow guiding valleys 2112, both of which radiate outwards from the top center of the inner cover 21 towards its edge. Figure 6 As shown, Figure 6 This is a cross-sectional view of the inner cover 21. The flow-guiding valley 2112 is concave in the drainage zone B, where condensate gradually expands from droplets into sheets. In the dissipation zone C, the height of the flow-guiding peak 2111 is level with the height of the flow-guiding valley 2112. Both the flow-guiding peak 2111 and the flow-guiding valley 2112 radiate outwards from the top center of the inner cover 21 towards its edge. The height difference between the flow-guiding peak 2111 and the flow-guiding valley 2112 decreases near the edge of the inner cover 21. Condensate flows from the top center of the inner cover 21 through the flow-guiding valley 2112 to the edge of the inner cover 21. When cooking, steam rises in the cooking appliance 1 and condenses at the top center of the inner lid 21. The lid 2 has a concave arc-shaped guide section 211 on the inner lid 21. The height difference between the guide peak 2111 and the guide valley 2112 causes the condensate to flow from the center of the inner lid 21 along the guide valley 2112 to one side of the edge of the inner lid 21. After the steam condenses, it will not condense at the top center of the inner lid 21, but will flow from the top center of the inner lid 21 to the surrounding area along the guide section 211. Finally, it flows along the inner surface of the inner pot 11 into the edge area where the rice is dry and hard. This makes the moisture and temperature inside the inner pot 11 coordinate and reach a balanced state, so that the overall moisture of the rice is more uniform. It will not be a state where the edges are dry and hard and the center is soft and mushy. Instead, the rice in the inner pot 11 will be in a state where the grains are distinct and the texture is moderately soft.
[0040] The aggregation area A is distributed within the plane 2113 and the arc surface 2114. The height of the guiding peak 2111 in aggregation area A is flush with the height of the guiding valley 2112. Aggregation area A is located at the top of the inner cover 21 and directly above the temperature sensor 4. Aggregation area A is essentially planar, but has a slight, gradual bulge at its rear end, forming a slight height difference between the guiding peak 2111 and the guiding valley 2112. Figure 4 As shown, Figure 4This diagram illustrates the churning direction (D) of the rice water inside the cooking appliance 1 and the condensate flow direction (E). The heating plate 3 is positioned around the lower perimeter of the inner pot 11. Because a temperature sensor 4 is located at the center, it does not generate heat. This results in the rice water churning in the direction D from the edge to the center. The steam temperature is relatively higher at the edge and relatively lower at the center, causing steam to accumulate in the cooler center. This is where the most water vapor condenses most easily and adheres to the inner surface of the inner lid 21.
[0041] The drainage zone B is distributed within the arc surface 2114. The height of the guiding peak 2111 in the drainage zone B gradually rises from the junction of the gathering zone A and the drainage zone B to the middle of the inner cover 21. The drainage zone B is used to increase the surface tension of the condensate. The drainage zone B is located in the middle of the inner side of the inner cover 21, directly above the heating plate 3. This drainage zone B experiences the greatest impact from steam directly above the heating plate 3. The dimensions of the guiding peak 2111 and the guiding valley 2112 are matched such that the height of the guiding peak 2111 gradually increases from the gathering zone A until it reaches its maximum value in the middle of the inner cover 21. Due to the ridges on the inner surface of the inner cover 21, the guiding peak 2111 and the guiding valley 2112 form a concave structure, with a height difference between them. The surface tension of the condensate will gradually increase as the guide peak 2111 rises. After the water surface increases, it can quickly absorb the water vapor condensate in the accumulation area A, thereby reducing the amount of condensate in the accumulation area A and preventing it from accumulating too much and falling to the center of the rice.
[0042] The dissipation zone B is distributed within the arc surface 2114. In the dissipation zone C, the height of the guiding peak 2111 gradually decreases from the center of the inner cover 21 to be level with the height of the guiding valley 2112. The dissipation zone C is located in the lower-middle part of the inner surface of the inner cover 21. The guiding peak 2111 in the dissipation zone C gradually decreases from its highest point, eventually becoming level with the guiding valley 2112. The reduction in the height difference between the guiding peak 2111 and the guiding valley 2112 leads to a decrease in the surface tension of the condensate. The condensate in the guiding zone B is thus dispersed and falls onto the inner surface of the inner pot 11. Because the area where the condensate falls has a high temperature, it is heated and evaporated again, thereby redistributing the moisture and improving the rice cooking effect.
[0043] During cooking, moisture in the cooking appliance 1 generates steam due to the heat. The concave arc-shaped guide section 211 effectively guides the steam back to the bottom of the inner pot 11, preventing excessive steam from accumulating on the inner surface of the inner lid 21 and dripping back onto the food. This allows the steam to return to the inner pot 11, effectively maintaining the moisture and temperature of the food, preventing excessive moisture evaporation, and preserving the texture of the food. The guide section 211 also improves the heat flow distribution on the inner surface of the inner lid 21, enhancing the even distribution of heat within the pot. Through its precisely designed concave structure, steam and hot air flow along specific paths, reducing heat concentration and uneven distribution, resulting in more even heating of the food within the pot, improving cooking performance, and preventing localized overcooking or undercooking.
[0044] The concave guide section 211 reduces the area where water droplets accumulate by changing the flow direction of steam, allowing it to flow more smoothly to the edge of the inner lid 21 or the drain hole on the inner pot 11 (not shown in the figure). This prevents water droplets from dripping directly onto the food, preserving the original flavor and texture of the ingredients. The concave design of the guide section 211 also enhances the seal between the inner lid 21 and the inner pot 11, ensuring that steam does not leak during cooking. Simultaneously, this design of the lid 2 makes the surface of the inner lid 21 more pressure-resistant and stronger, able to withstand higher temperature changes, improving the stability and durability of the cooking appliance 1. Over time, steam and grease may accumulate on the inner surface of the inner lid 21. The concave guide section 211 helps reduce the retention of steam and grease, preventing their accumulation on the inner surface of the inner lid 21, thereby reducing the formation of grease and grime. This not only keeps the inner lid 21 clean but also effectively reduces the difficulty of cleaning. Through the concave guide design, the functionality and design of the inner lid 21 are enhanced. With smoother steam flow, food becomes more moist and has a better texture during cooking. This optimized design enhances the overall cooking experience for users.
[0045] Third specific embodiment
[0046] The inner cover 21 has a cover base 212 and a mounting opening 213 at its top. The cover base 212 is fitted into the mounting opening 213. A mounting portion 2131 is provided inside the mounting opening 213. The cover base 212 has a mounting groove 2121, and the mounting portion 2131 is embedded in the mounting groove 2121. In this embodiment, the mounting opening 213 is circular, and the mounting groove 2121 is annular. The shapes of the mounting opening 213 and the mounting groove 2121 can be set according to actual needs. In this embodiment, the cover base 212 is made of a flexible material, and there is an annular mounting groove 2121 in the middle of the cover base 212. The shape and size of the mounting groove 2121 match the mounting opening 213. During installation, the cover base 212 is squeezed to match the mounting groove 2121 with the mounting opening 213 to achieve fixation.
[0047] Fourth specific embodiment
[0048] The upper end of the lid 212 is provided with a handle 2122. The handle 2122 is cylindrical, wider at the top and narrower at the bottom. The cylindrical handle 2122 has a non-slip function, making it easy to pick up during normal use. The handle 2122 facilitates the opening of the inner lid 21 from the inner pot 11. The top of the handle 2122 is flat, allowing the inner lid 21 to be placed upside down on a table without tipping over. For hygiene purposes, the inner lid 21 can be placed upside down, and the cylindrical handle 2122 can be placed stably on any flat surface. The shape of the handle 2122 is not limited to cube or elongated shape. The inner cover 212 is in the shape of a cube or similar object. A handle 2123 is provided at the lower end of the cover 212. The handle 2123 has concave sides. When the inner cover 21 is placed upside down on any flat surface, the handle 2123 can be used to lift the inner cover 21. The concave sides of the handle 2123 make it easier to pick up the flipped inner cover 21. The handle 2123 has a convex semi-racetrack-shaped sheet structure with concave structures on both sides for anti-slip purposes. When the inner cover 21 is inverted, it can be lifted by grasping the sheet structure of the handle 2123. The cover 212 is designed so that it can be picked up from both ends for convenient user operation.
[0049] Fifth specific embodiment
[0050] The inner cover 21 has an annular sealing element 214 along its edge, which seals the inner cover 21 and the inner pot 11. The sealing element 214 has a positioning part 2141. The edge of the inner cover 21 extends into a platform 215, which has a first positioning port 2151. The edge of the inner pot 11 has a second positioning port 111. The positioning part 2141 engages with the first positioning port 2151 and the second positioning port 111, respectively. The annular sealing element 214 may be made of silicone. The positioning part 2141 is an outwardly protruding structure extending from the sealing element 214, and it matches the first positioning port 2151 and the second positioning port 111.
[0051] The main function of the seal 214 is to improve the sealing performance between the inner lid 21 and the inner pot 11. During cooking, the seal 214 prevents the leakage of steam, heat, and gas by tightly contacting the edge of the inner pot 11. Good sealing helps maintain the temperature and humidity inside the pot, improving cooking efficiency; the seal 214 effectively prevents steam from leaking from the gap between the inner lid 21 and the inner pot 11. When the water in the inner pot 11 is heated to its boiling point, a large amount of steam is generated. The seal 214 prevents this steam from escaping, ensuring that the temperature inside the pot remains within the ideal range, avoiding steam loss, excessive evaporation of water, or wasted energy; by maintaining a sealed environment, the seal 214 between the inner lid 21 and the inner pot 11 helps maintain the pressure and temperature inside the pot. This not only helps improve the cooking efficiency of food but also promotes the retention of nutrients in food, enhancing the taste and nutritional value of the food.
[0052] The seal 214 prevents air, dust, or external contaminants from entering the pot, ensuring a clean cooking environment. Especially during high-temperature cooking, the sealed environment effectively isolates adverse external factors, maintaining food hygiene and safety. The sealing design also reduces water splashing or liquid overflow at high temperatures. Particularly during heating, the good seal prevents liquid from overflowing due to vigorous steam expansion, reducing kitchen cleaning hassles and lowering safety hazards during cooking. This excellent sealing design not only enhances product functionality but also improves the user experience. Users don't need to worry about leaks or steam loss from the inner lid 21, making the cooking process smoother and more efficient.
[0053] The inner lid 21 is provided with a steam vent 216, and the pot lid 2 is provided with a silicone part 22. When the pot lid 2 is closed, the silicone part 22 connects with the steam vent 216 to form a steam venting channel. The first positioning port 2151 is on the opposite side of the steam vent 216 and on the central axis of the inner lid 21. The cooperation of the positioning part 2141 with the first positioning port 2151 and the second positioning port 111 fixes the steam vent 216 on the inner lid 21 in the same position as the cooking appliance 1, ensuring that the steam vent 216 and the silicone part 22 are properly matched. The matching of the steam vent 216 and the silicone part 22 on the pot lid 2 also positions the sealing part 214. After the lid is closed, a steam venting channel is formed to release water vapor.
[0054] This utility model also proposes a cooking appliance 1, which is a rice cooker. The cooking appliance 1 includes a lid 2. The specific structure of the lid 2 is as described in the above embodiments. Since this cooking appliance 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0055] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
