Description

Technical Field

[0001] The cooking appliance of the utility model relates to the technical field, in particular to a container body. Background Art

[0002] During the cooking process of the existing container body, as the cooking time increases, the temperature of the container body also gradually increases. However, the temperatures at different positions of the container body are often different, resulting in uneven heating of the food materials in the container body. To improve the uniformity of food material heating during the cooking process, slow heating is often required during cooking, thereby reducing the cooking efficiency and the user experience. Summary of the Utility Model

[0003] This application provides a container body, which is used to solve the problems that during the cooking process, the temperatures at different positions of the container body are different, resulting in uneven heating of the food materials in the container body, low cooking efficiency, and poor user experience.

[0004] This application provides a container body, which includes a main body and a temperature equalizing plate. Along the thickness direction of the container body, the temperature equalizing plate is located outside the main body. The temperature equalizing plate includes a plate body, and the plate body has a cavity for containing a homogenizing liquid. The inner wall of the plate body facing the cavity is provided with a plurality of protruding parts, and there are gaps between adjacent protruding parts. The sizes of at least two of the gaps are different.

[0005] In this solution, during the cooking process of the container body, the heat of the heat source is conducted to the main body through the temperature equalizing plate, so that each position of the main body is heated evenly, avoiding the bottom burning caused by the high temperature at the position close to the center of the main body and the ineffective heating of the food due to the low temperature at the position far from the center. The temperatures at each position of the container body are uniform, the cooking rate is accelerated, which is beneficial to improving the cooking performance of the container body and the user experience. In addition, there are gaps between adjacent protruding parts, and the sizes of at least two of the gaps are different, that is, the protruding parts are unevenly distributed on the plate body, so as to change the temperature equalizing ability of each position of the temperature equalizing plate. For example, the temperature equalizing ability of the position of the temperature equalizing plate close to the heat source is better than that of other positions, reducing the risk of bottom burning at the position of the container body close to the heat source, further improving the cooking performance of the container body, and thus improving the cooking quality.

[0006] In this solution, along the radial direction of the container body, the plate body includes a first region and a second region located outside the first region. The density of the protruding parts in the first region is greater than the density of the protruding parts in the second region.

[0007] In this solution, since the density of the raised parts in the first region is greater than that in the second region, the circulation rate of the homogeneous liquid in the first region is greater than that in the second region. As a result, the temperature equalization ability of the first region is better than that of the second region, enabling the first region to quickly equalize the temperature and reducing the risk of bottom sticking caused by excessive local temperature rise under the action of the heating source. The second region is not in direct contact with the heating source, so the risk of bottom sticking is relatively low, and the density of the raised parts does not need to be too large to meet the temperature equalization requirements of the second region.

[0008] In this solution, the raised parts in the first region are evenly distributed.

[0009] In this solution, since the first region is the heating area directly covered by the heating source and the raised parts in the first region are evenly distributed, it can further reduce the risk of bottom sticking at the position where the first region of the plate covers the body, which is beneficial to improving the safety during the cooking of the container body. In addition, the raised parts can support the plate. Since the container body is generally arc-shaped, the plate is also generally arc-shaped. The first region of the plate is more convex along the thickness direction of the container body compared to other positions. The even distribution of the raised parts in the first region is beneficial to improving the structural strength of the first region of the plate.

[0010] In this solution, the multiple raised parts in the second region include multiple first raised parts and multiple second raised parts. The circumferential gap between adjacent first raised parts is greater than the circumferential gap between adjacent second raised parts. Along the radial direction of the container body, the first raised parts and the second raised parts are alternately distributed.

[0011] In this solution, the number of the first raised parts is less than that of the second raised parts. The alternating distribution of the first raised parts and the second raised parts can make the second region heat evenly along the radial direction of the container body, and is beneficial to reducing the number of raised parts arranged in the second region. Furthermore, it is beneficial to reducing the production cost of the temperature equalization plate and thus reducing the production cost of the container body.

[0012] In this solution, the ratio of the area S1 of the first region to the area S2 of the second region satisfies: 1 / 5 ≤ S1 / S2 ≤ 1 / 2.

[0013] In this solution, the areas of the first region and the second region are appropriate, enabling the temperature equalization plate to have good temperature equalization ability without increasing the production cost.

[0014] In this solution, the shape of the raised part is cylindrical or conical.

[0015] In this solution, the raised portion is raised relative to the plate body along the thickness direction of the container body, and the shape of the raised portion is cylindrical or conical, that is, the outer wall of the raised portion is arc-shaped, which is beneficial to increase the disturbance of the homogeneous liquid by the raised portion along the thickness direction and radial direction of the container body, further increase the circulation flow rate of the homogeneous liquid, and further improve the temperature uniformity ability.

[0016] In this solution, the plate body includes a first cover plate and a second cover plate spaced apart along the thickness direction of the container body, the first cover plate is located on the side of the second cover plate away from the body, and the protrusion is provided on the first cover plate and / or the second cover plate.

[0017] In this solution, the first cover plate and the second cover plate can enclose the above-mentioned cavity, and the protrusion is provided on the first cover plate and / or the second cover plate. The protrusion can support the first cover plate and / or the second cover plate, thereby improving the structural strength of the first cover plate and / or the second cover plate, reducing the risk of leakage of the homogenized liquid, and thus improving the reliability and safety of the container body during cooking.

[0018] In this solution, the container body further includes a composite bottom sheet, which is connected to the side of the temperature balancing plate facing away from the main body and covers the temperature balancing plate. The material of the composite bottom sheet is aluminum alloy.

[0019] In this solution, in this embodiment, the composite bottom plate made of aluminum alloy material has good thermal conductivity and can quickly transfer heat to the temperature equalizing plate, further improving the temperature equalizing rate of the container body.

[0020] In this solution, a groove is provided on the outer side wall of the body, and the temperature uniformity plate and the composite bottom plate are both located in the groove.

[0021] In this solution, the groove is used to accommodate the temperature averaging plate and the composite bottom sheet. Along the thickness direction of the container body, the temperature averaging plate is located between the main body and the composite bottom sheet, so that the composite bottom sheet and the outer wall of the main body are smoothly connected, thereby improving the aesthetics of the container body.

[0022] In this solution, the ratio of the area S3 of the bottom wall of the groove to the surface area S4 of the outer side wall of the body satisfies: 1 / 3≤S3 / S4≤1 / 2.

[0023] In this solution, the area of the bottom wall of the groove and the surface area of the outer wall of the body are moderate, which can enable the container body to have a good temperature uniformity capability without increasing the production cost of the container body.

[0048] To better understand the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0049] In a specific embodiment, the present application will be further described in detail below through specific embodiments and with reference to the accompanying drawings.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0053] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the angles shown in the accompanying drawings, and should not be construed as a limitation on the embodiments of the present application.

[0054] The embodiments of the present application provide a container body 1, and the container body 1 can be cooking pots such as a steamer, a wok, and a casserole. As Figure 1 and Figure 2 shown, the container body 1 includes a main body 11 and a temperature equalizing plate 12. Along the thickness direction of the container body 1, the temperature equalizing plate 12 is located outside the main body 11. As Figure 3 and Figure 4 shown, the temperature equalizing plate 12 includes a plate body 121. The plate body 121 has a cavity for accommodating a homogeneous liquid 123. The inner wall of the plate body 121 facing the cavity is provided with a plurality of protruding portions 1211. There are gaps between adjacent protruding portions 1211, and the sizes of at least two gaps are different.

[0055] Among them, the heat pipe 12 (also known as a heat pipe heat spreader or a thermal diffusion plate) is a device capable of conducting heat. The heat pipe 12 includes a sealed container filled with a homogeneous liquid 123 (such as water or a special coolant) inside. This container is usually made of a material with good thermal conductivity, such as copper or aluminum. Inside the heat pipe 12, the homogeneous liquid 123 evaporates after being heated by a heat source. The vapor moves to the cold area through a pressure difference, condenses back to the liquid state there, and then returns to the hot area through capillary action or other mechanisms, thus forming a cycle process. The heat pipe 12 can provide better thermal uniformity because it can quickly disperse heat over a large area, effectively reducing the temperature of local hot spots and improving the stability and lifespan of the container body 1.

[0056] During the cooking process of the container body 1, the heat of the heating source is conducted to the main body 11 through the heat pipe 12, so that each position of the main body 11 is heated evenly, avoiding the bottom burning caused by the high temperature at the position close to the center of the main body 11 and the ineffective heating of food due to the low temperature at the position far from the center. This makes the temperature of each position of the container body 1 uniform, speeds up the cooking rate, is beneficial to improving the cooking performance of the container body 1, and enhances the user experience.

[0057] Specifically, after the heat pipe 12 starts to be heated, the position of the heat pipe 12 close to the heating source is the high-temperature area, and the position far from the heating source is the low-temperature area. A temperature difference zone is formed between the high-temperature area and the low-temperature area. At this time, the homogeneous liquid 123 will start to circulate, that is, the homogeneous liquid 123 converts between the vapor and liquid states, so that the heat in the high-temperature area can be transferred to the low-temperature area until the heat pipe 12 reaches a constant temperature, that is, the isothermal state. Among them, the above-mentioned constant temperature is related to the material selected for the homogeneous liquid 123. Normally, the cooking temperature is generally 180 degrees Celsius to 200 degrees Celsius, and the maximum is 250 degrees Celsius. For example, if the container body 1 is only used for stir-frying, a pure water heat pipe 12 can be selected. After exceeding 100 degrees Celsius, the evaporation of the homogeneous liquid 123 will be accelerated, and the heat pipe 12 is already in the isothermal state. If the container body 1 needs to be used for stir-frying over high heat, a graphene heat pipe 12 can be selected. The graphene heat pipe 12 can be applicable to a high temperature of 250 degrees Celsius, which is convenient for the heat pipe 12 to make the container body 1 reach the isothermal state. The type and material selected for the heat pipe 12 in this application are not limited, as long as the container body 1 is made isothermal during the cooking process.

[0058] In this embodiment, the cavity further includes a mesh plate 122, and the homogenized liquid 123 can flow in the plate body 121 through the mesh plate 122. During the cooking process, the homogenized liquid 123 on the side of the plate body 121 close to the heat source vaporizes as the temperature rises. The vaporized homogenized liquid 123 moves through the mesh plate 122 to the side of the plate body 121 away from the heat source. Subsequently, the vaporized homogenized liquid 123 cools and liquefies, and transfers heat to the position with a lower temperature of the main body 11, increasing the temperature of this position. Then, the liquefied homogenized liquid 123 flows back to the side of the plate body 121 close to the heat source through the mesh plate 122. The liquefied homogenized liquid 123 vaporizes when heated and then flows to the side of the plate body 121 away from the heat source again. That is, the homogenized liquid 123 can circulate in the cavity to enable the container body 1 to achieve a uniform temperature effect. At the same time, a convex portion 1211 is provided in the plate body 121, and the convex portion 1211 can accelerate the process of gas-liquid circulation of the homogenized liquid 123, so that the temperature of the container body 1 can quickly rise to an overall uniform temperature, achieving the purpose of uniformly heating the food in the container body 1. In addition, there are gaps between adjacent convex portions 1211, and the sizes of at least two gaps are different, that is, the convex portions 1211 are unevenly distributed on the plate body 121, which can change the temperature uniformity ability of each position of the temperature uniformity plate 12. For example, the temperature uniformity ability of the position of the temperature uniformity plate 12 close to the heat source is better than that of other positions, reducing the risk of bottom burning at the position of the container body 1 close to the heat source, further improving the cooking performance of the container body 1, and thus enhancing the cooking quality.

[0059] In addition, during the continuous heating process of the container body 1, the setting of the temperature uniformity plate 12 enables the container body 1 to achieve a uniform temperature effect without slow heating, thus not reducing the cooking efficiency.

[0060] Among them, the temperature uniformity plate 12 provided in this application has the same principle as the heating tube. In other embodiments, the temperature uniformity plate 12 can be replaced by a heating tube.

[0061] In a possible implementation manner, as Figure 5 shown, along the radial direction of the container body 1, the plate body 121 includes a first region 1212 and a second region 1213 located on the outer periphery of the first region 1212. The density of the convex portions 1211 in the first region 1212 is greater than the density of the convex portions 1211 in the second region 1213.

[0062] In this embodiment, the first region 1212 can be a heating region directly covered by a heating source, and the second region 1213 can be a region not directly covered by the heating source. That is, the heating source transfers heat to the second region 1213 through the first region 1212, thereby achieving heating of the second region 1213. Since the density of the protrusions 1211 in the first region 1212 is greater than the density of the protrusions 1211 in the second region 1213, the circulation rate of the homogeneous liquid 123 located in the first region 1212 is greater than the circulation rate of the homogeneous liquid 123 located in the second region 1213. Furthermore, the temperature equalization ability of the first region 1212 is better than that of the second region 1213, enabling the first region 1212 to quickly equalize the temperature and reducing the risk of bottom burning caused by excessive local temperature rise of the first region 1212 under the action of the heating source. The second region 1213 is not in direct contact with the heating source, and the risk of bottom burning is relatively low. The density of the protrusions 1211 does not need to be too large to meet the temperature equalization requirements of the second region 1213.

[0063] In one possible implementation, as Figure 5 shown, the protrusions 1211 in the first region 1212 are evenly distributed.

[0064] In this embodiment, since the first region 1212 is a heating region directly covered by a heating source and the protrusions 1211 in the first region 1212 are evenly distributed, it can further reduce the risk of bottom burning at the position where the first region 1212 of the plate body 121 covers the main body 11, which is beneficial to improving the safety of the container body 1 during cooking. In addition, the protrusions 1211 can support the plate body 121. Since the container body 1 is generally arc-shaped, the plate body 121 is also generally arc-shaped. The first region 1212 of the plate body 121 is more convex along the thickness direction of the container body 1 compared to other positions. The even distribution of the protrusions 1211 in the first region 1212 is beneficial to improving the structural strength of the first region 1212 of the plate body 121.

[0065] In one possible implementation, as Figure 5 shown, the multiple protrusions 1211 in the second region 1213 include multiple first protrusions 1213a and multiple second protrusions 1213b. The circumferential gap between adjacent first protrusions 1213a is greater than the circumferential gap between adjacent second protrusions 1213b. Along the radial direction of the container body 1, the first protrusions 1213a and the second protrusions 1213b are alternately distributed.

[0066] In this embodiment, the number of first protrusions 1213a is less than the number of second protrusions 1213b. The alternating distribution of the first protrusions 1213a and the second protrusions 1213b can make the second area 1213 heated evenly along the radial direction of the container body 1, and is beneficial to reducing the number of protrusions 1211 set in the second area 1213, thereby helping to reduce the production cost of the temperature equalizing plate 12, and further reducing the production cost of the container body 1.

[0067] In one possible implementation, Figure 5 As shown, the ratio of the area S1 of the first region 1212 to the area S2 of the second region 1213 satisfies: 1 / 5≤S1 / S2≤1 / 2. The area ratio S1 / S2 can be 1 / 5, 1 / 4, 1 / 3, 1 / 2, etc.

[0068] In this embodiment, when the area ratio S1 / S2 is small, that is, the area of the first region 1212 is too small compared to the area of the second region 1213, the temperature averaging capability of the container body 1 at the location heated by the heat source is reduced, that is, the anti-sticking capability of the container body 1 at the location heated by the heat source is reduced. When the area ratio S1 / S2 is large, that is, the area of the first region 1212 is too large compared to the area of the second region 1213, the number of protrusions 1211 in the plate body 121 increases, increasing the cost. Therefore, in this embodiment, the areas of the first region 1212 and the second region 1213 are moderate, which can ensure that the temperature averaging plate 12 has good temperature averaging capability without increasing production costs.

[0069] In one possible implementation, Figure 4 As shown, the shape of the protrusion 1211 is cylindrical or conical.

[0070] In this embodiment, along the thickness direction of the container body 1, the protrusion 1211 protrudes relative to the plate body 121, and the shape of the protrusion 1211 is cylindrical or conical, that is, the outer wall of the protrusion 1211 is arc-shaped, which is beneficial to increase the disturbance of the homogenous liquid 123 by the protrusion 1211 along the thickness direction and radial direction of the container body 1, further increase the circulation flow rate of the homogenous liquid 123, and further improve the temperature uniformity ability.

[0071] In one possible implementation, Figure 4 As shown, the plate body 121 includes a first cover plate 1214 and a second cover plate 1215 arranged at intervals along the thickness direction of the container body 1. The first cover plate 1214 is located on the side of the second cover plate 1215 away from the main body 11, and the protrusion 1211 is arranged on the first cover plate 1214 and / or the second cover plate 1215.

[0072] In this embodiment, the first cover plate 1214 and the second cover plate 1215 can enclose the above-mentioned cavity, and the protrusion is provided on the first cover plate 1214 and / or the second cover plate 1215. The protrusion 1211 can support the first cover plate 1214 and / or the second cover plate 1215, thereby improving the structural strength of the first cover plate 1214 and / or the second cover plate 1215, reducing the risk of leakage of the homogenized liquid 123, and thus improving the reliability and safety of the container body 1 during cooking.

[0073] Specifically, the first cover plate 1214 may be provided with a protrusion 1211, which protrudes toward the second cover plate 1215 along the thickness direction of the container body 1. The second cover plate 1215 may be provided with a protrusion 1211, which protrudes toward the first cover plate 1214 along the thickness direction of the container body 1.

[0074] In one possible implementation, Figure 2 As shown, the container body 1 further includes a composite bottom sheet 13 , which is connected to the side of the temperature balancing plate 12 away from the body 11 and covers the temperature balancing plate 12 . The composite bottom sheet 13 is made of aluminum alloy.

[0075] In this embodiment, the composite bottom sheet 13 made of aluminum alloy has good thermal conductivity and can quickly transfer heat to the temperature equalizing plate 12 , further improving the temperature equalization rate of the container body 1 .

[0076] In one possible implementation, Figure 3 and Figure 6 As shown, a groove 111 is provided on the outer wall of the body 11 , and the temperature homogenizing plate 12 and the composite bottom plate 13 are both located in the groove 111 .

[0077] In this embodiment, the groove 111 is used to accommodate the temperature averaging plate 12 and the composite bottom film 13. Along the thickness direction of the container body 1, the temperature averaging plate 12 is located between the main body 11 and the composite bottom film 13, so as to achieve a smooth connection between the composite bottom film 13 and the outer wall of the main body 11, thereby improving the aesthetics of the container body 1. The main body 11, the temperature averaging plate 12, and the composite bottom film 13 can be connected by welding or other methods, and the connection between the groove 111, the temperature averaging plate 12, and the composite bottom film 13 can be polished to reduce the roughness of the outer surface of the container body 1 and improve the reliability of the connection between the main body 11, the temperature averaging plate 12, and the composite bottom film 13. This application does not limit the method of connecting the main body 11, the temperature averaging plate 12, and the composite bottom film 13.

[0078] In addition, in other embodiments, the temperature plate 12 can be attached to the outer side of the outer wall of the body 11. In other embodiments, the temperature plate 12 is connected to the base material of the container body 1, and the base material is then formed into the container body 1.

[0079] In one possible implementation, Figure 2As shown, the ratio of the area S3 of the bottom wall of the groove 111 to the surface area S4 of the outer side wall of the body 11 satisfies: 1 / 3 ≤ S3 / S4 ≤ 1 / 2. The area ratio S3 / S4 can be 1 / 3, 2 / 5, 1 / 2, etc.

[0080] In this embodiment, when the area ratio S3 / S4 is relatively small, the area of the bottom wall of the groove 111 is too small compared to the surface area of the outer side wall of the body 11, that is, the area of the heat pipe 12 is small, reducing the heat equalizing ability of the heat pipe 12 for the container body 1; when the area ratio S3 / S4 is relatively large, the area of the bottom wall of the groove 111 is too large compared to the surface area of the outer side wall of the body 11, that is, the area of the heat pipe 12 is large, increasing the production cost of the container body 1. Therefore, in this embodiment, the area of the bottom wall of the groove 111 and the surface area of the outer side wall of the body 11 are appropriate, enabling the container body 1 to have good heat equalizing ability and not increasing the production cost of the container body 1.

[0081] The above is only the specific implementation manner of the embodiments of the present application, but the protection scope of the embodiments of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application. Therefore, the protection scope of the embodiments of the present application shall be subject to the protection scope of the claims.
