Heating plate assembly and liquid heating container

Abstract

This application provides a heating plate assembly and a liquid heating container. The heating plate assembly includes a plate body and a heating tube. The heating tube is installed on the plate body and is annular. The heating tube includes a heating part and connecting parts located at both ends of the heating part. Along the radial direction of the plate body, the center of the heating tube is located between the center of the plate body and the heating part. This increases the furthest distance between the center of the plate body and the width center of the heating part in the radial direction of the plate body, thereby increasing the lever arm of the force exerted on the food in the liquid heating container during rotation and tumbling, and further increasing the torque of the force. This ensures that the food in the liquid heating container can be fully tumbled under the action of the heating plate assembly, thereby improving the heating uniformity of the food and reducing the risk of undercooked food.

Description

Technical Field

[0001] This application relates to the field of household appliances, and more particularly to a heating plate assembly and a liquid heating container. Background Technology

[0002] Liquid heating containers typically include a pot body and a heating plate located at the bottom of the pot body. The heating plate has heating elements for heating the liquid and food inside the pot. In existing technology, the structure of the heating plate cannot guarantee even heating of the food inside the pot when boiling water, affecting the user experience. Utility Model Content

[0003] This application provides a heating plate assembly and a liquid heating container, which can solve the problem of uneven heating of food in liquid heating containers in the prior art.

[0004] The first aspect of this application provides a heating plate assembly, comprising: a plate body; a heating tube installed on the plate body, the heating tube being annular, the heating tube including a heating portion and connecting portions located at both ends of the heating portion; along the radial direction of the plate body, the center of the heating tube is located between the center of the plate body and the heating portion.

[0005] In the above scheme, the food in the liquid heating container rotates and tumbles under the heating action of the heating plate assembly, and the center of rotation of the food coincides with the center of the plate in the axial direction of the liquid heating container. The furthest distance in the radial direction between the center of the plate and the center of the width of the heating element is the lever arm of the force exerted on the food in the liquid heating container during rotation and tumbling. Therefore, it can be understood that the heating plate assembly provided in this application embodiment, by setting the heating tube eccentrically relative to the plate, makes the heating element closer to the edge of the plate. Compared with the structure where the heating tube is concentrically set with the plate, it can increase the furthest distance in the radial direction between the center of the plate and the center of the width of the heating element, thereby increasing the lever arm of the force exerted on the food in the liquid heating container during rotation and tumbling, and thus increasing the torque of the force. This ensures that the food inside the liquid heating container can tumble fully under the action of the heating plate assembly, thereby improving the heating uniformity of the food in the liquid heating container, reducing the risk of undercooked food, and improving the user experience.

[0006] In one possible design, the distance between the center of the heating element and the center of the disk is greater than 2 mm.

[0007] In the above scheme, when L is greater than 2mm, it can ensure that the farthest distance between the center of the plate and the width center of the heating part in the radial direction of the plate is moderate, so as to ensure that the food in the pot has a good tumbling effect, further improving the heating uniformity of the food, thereby further reducing the risk of the food being undercooked.

[0008] In one possible design, the outer diameter of the heating element is 84mm to 120mm.

[0009] In the above scheme, with the width W of the heating element remaining constant, if the outer diameter is too small (e.g., less than 84mm), the furthest radial distance between the center of the plate and the center of the width of the heating element will be too small, resulting in a reduced tumbling effect on the food. If the outer diameter is too large (e.g., greater than 120mm), the size of the plate will increase, leading to increased cost and weight of the heating plate assembly, but without a significant improvement in the tumbling effect on the food. Therefore, the optimal heating plate assembly is achieved when the outer diameter of the heating element is between 84mm and 120mm, ensuring an effective improvement in the tumbling effect of the food inside the pot while appropriately reducing the weight and cost of the heating plate assembly.

[0010] In one possible design, the width of the heating element is 11mm to 17mm.

[0011] In the above solutions, when W is too small (e.g., less than 11 mm), the overall volume of the heating element is too small, resulting in a small area of ​​high-temperature zone on the plate. This leads to reduced heating uniformity and efficiency of the heating plate assembly for the liquid and food in the liquid heating container. Furthermore, with the inner diameter of the heating tube remaining constant, a small W also results in a smaller radial distance between the center of the plate and the center of the width of the heating element, thus reducing the tumbling effect of the food. When W is too large (e.g., greater than 17 mm), the overall volume of the heating element is too large, increasing the cost and weight of the heating tube, and consequently, the cost and weight of the heating plate assembly. However, the heating uniformity and efficiency of the heating plate assembly for the liquid and food in the liquid heating container are not significantly improved, nor is the tumbling effect of the food significantly enhanced. Therefore, when W is between 11 mm and 17 mm, the heating efficiency, heating uniformity and efficiency of the heating plate assembly for the liquid and food in the liquid heating container, and the tumbling effect of the food in the liquid heating container can be improved, while the weight and cost of the heating plate assembly can be appropriately reduced.

[0012] In one possible design, the plate body includes a plate body and a heat-conducting plate. Along the thickness direction of the heating plate assembly, one side surface of the heat-conducting plate is fixedly connected to the plate body, and the other side surface is fixedly connected to the heating tube.

[0013] In the above solution, the heat-conducting plate is located between the heating tube and the plate body. It is used to quickly conduct the heat from the heating tube to the plate body, thereby improving the heat transfer efficiency when the heating tube transfers heat to the plate body. The heat-conducting plate can also conduct heat in the radial direction of the plate body, thereby expanding the heat transfer area between the heating tube and the plate body. This is beneficial to improving the heating uniformity of the heating plate assembly for the liquid and food in the pot.

[0014] In one possible design, the thickness H1 of the disk body is 0.3 mm to 1 mm.

[0015] In the above scheme, if H1 is too small (e.g., less than 0.3 mm), the plate body is too thin, resulting in insufficient structural strength and affecting the stability and reliability of the heating plate assembly. If H1 is too large (e.g., greater than 1 mm), the plate body is too thick, reducing its heat conduction effect. The plate body will conduct heat radially, causing heat loss and reducing the heating efficiency of the heating plate assembly. This also increases the cost of the plate body. Therefore, when H1 is between 0.3 mm and 1 mm, it ensures sufficient stability and reliability of the heating plate assembly, improves its heating efficiency, and appropriately reduces its cost.

[0016] In one possible design, the thickness H2 of the heat-conducting plate is 1.2 mm to 3 mm.

[0017] In the above scheme, if H2 is too small (e.g., less than 1.2 mm), the heat-conducting plate will be too thin, resulting in insufficient structural strength and affecting the stability and reliability of the heating plate assembly. If H2 is too large (e.g., greater than 3 mm), the heat-conducting plate will be too thick, reducing its heat conduction effect. The heat-conducting plate will conduct heat radially, causing heat loss and reducing the heating efficiency of the heating plate assembly. This also increases the cost of the heat-conducting plate. Therefore, when H2 is between 1.2 mm and 3 mm, it ensures sufficient structural strength for the heating plate assembly while reducing the lateral heat dissipation effect of the heat-conducting plate. This helps improve the heating efficiency of the heating plate assembly and appropriately reduce its cost.

[0018] In one possible design, the heating plate assembly further includes a thermostat, which is electrically connected to the connecting part; the thermostat is mounted on the plate body, and the heating tube is arranged around the thermostat circumferentially.

[0019] In the above scheme, the thermostat can be used to control the opening and closing of the heating element and adjust its heating temperature, thereby achieving intelligent temperature control and anti-dry-burning function for the liquid heating container. The heating element is arranged around the thermostat to integrate the heating plate assembly, which helps to reduce the overall volume of the heating plate assembly and save internal space in the liquid heating container.

[0020] A second aspect of this application provides a liquid heating container, including a kettle body and the heating plate assembly described above, wherein the heating plate is fixedly connected to the kettle body.

[0021] In the above solution, the pot body is used to hold liquid and food, and the plate is fixedly connected to the bottom of the pot body so that the heating plate assembly can heat the liquid and food in the pot body. When the heating plate assembly is used, it is beneficial to improve the heating uniformity of the food in the liquid heating container, reduce the risk of the food being undercooked, and improve the user experience.

[0022] In one possible design, the plate body is provided with a receiving groove; at least a portion of the bottom of the pot body extends into the receiving groove and is fixedly connected to the receiving groove.

[0023] In the above design, the plate can serve as the bottom of the kettle body, forming a cavity with the kettle body to hold liquids and ingredients. This allows the plate to directly contact the liquids and ingredients inside the kettle, improving the heat conduction of the heating element and thus increasing its heating efficiency. At least a portion of the bottom of the kettle body extends into and is fixedly connected to the receiving groove. This connection structure increases the contact area between the kettle body and the plate, improving the stability of the connection. Furthermore, the receiving groove can limit the kettle body radially, enhancing the reliability and stability of its installation.

[0024] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0045] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0046] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0047] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0048] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0049] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0050] This application provides a liquid heating container, such as... Figure 1 and Figure 2 As shown, the liquid heating container includes a pot body 4 and a heating plate assembly. The pot body 4 is used to hold liquids and ingredients (tea, herbs, beans, etc.). The heating plate assembly includes a plate body 1 and a heating tube 2 mounted on the plate body 1. The plate body 1 is fixedly connected to the bottom of the pot body 4 so that the heating plate assembly can heat the liquids and ingredients in the pot body 4. The heating tube 2 has a ring structure, including a heating part 21 and connecting parts 22 located at both ends of the heating part 21. The heating part 21 is used to heat the liquids and ingredients in the pot body 4, and the connecting parts 22 are the cooling pins of the heating tube 2, which are used to connect with other electrical components in the liquid heating container. During the operation of the heating plate assembly, because the temperature of the heating part 21 is higher and the temperature of the connecting parts 22 is lower, when the heating tube 2 conducts heat to the plate body 1, a high-temperature region 101 corresponding to the heating part 21 and a low-temperature region 102 corresponding to the connecting parts 22 can be formed on the plate body 1. The structure of the heating plate assembly is as follows. Figure 3 As shown, the heating tube 2 is eccentrically positioned relative to the disc body 1: along the radial direction X of the disc body 1, the center B of the heating tube 2 is located between the center A of the disc body 1 and the heating part 21, that is, the center B of the heating tube 2 does not coincide with the center A of the disc body 1, and the center B of the heating tube 2 is closer to the high-temperature area on the disc body 1 than the center A of the disc body 1, so that the heating part 21 is closer to the edge of the disc body 1.

[0051] In this embodiment of the application, when the heating plate assembly is working, the movement path of the liquid and food inside the pot body 4 is as follows: Figure 2The arrows in the diagram are as follows: As shown by the solid arrow, the liquid near the high-temperature region 101 at the bottom of the pot body 4 experiences a temperature increase and a decrease in density after being heated, allowing it to move upwards along the axial direction Z of the pot body 4. Simultaneously, the liquid near the high-temperature region 101 generates bubbles when heated, and these bubbles also move upwards along the axial direction Z of the pot body 4. At this time, the food at the bottom of the pot body 4 moves upwards synchronously under the influence of the bubbles and liquid. When the bubbles reach the top of the pot body 4, they burst, propelling the food along the radial direction X of the pot body 4 towards the other end of the pot body 4. As shown by the dashed arrow, when the liquid and food near the high-temperature region 101 at the bottom of the pot body 4 move upwards along the axial direction Z of the pot body 4, the liquid and food near the low-temperature region 102 at the bottom of the pot body 4 can move towards the high-temperature region 101, allowing the liquid and food in the low-temperature region 102 to be further heated. Simultaneously, the liquid above the low-temperature region 102 can move downwards to fill the low-temperature region 102.

[0052] Combination Figure 4 As shown, the food in the pot body 4 can rotate and tumble under the heating action of the heating plate assembly. The rotation center C of the food coincides with the center A of the plate body 1 along the axial direction Z of the pot body 4. The farthest distance r between the center A of the plate body 1 and the width center of the heating part 21 along the radial direction X of the plate body 1 is the lever arm of the force exerted on the food in the pot body 4 during rotation and tumbling. Therefore, it can be understood that the heating plate assembly provided in this embodiment of the application, by biasing the heating tube 2 toward the high-temperature region 101 of the plate body 1, makes the heating part 21 closer to the edge of the plate body 1. Compared to the structure where the heating element 2 and the plate 1 are concentrically arranged, this design increases the furthest distance r between the center A of the plate 1 and the width center of the heating element 21 in the radial direction X of the plate 1. This increases the lever arm of the force exerted on the food in the pot 4 during rotation and tumbling, thereby increasing the torque of the force. This ensures that the food inside the pot 4 can be fully tumbled under the action of the heating plate assembly, thus improving the uniformity of heating of the food in the pot 4, reducing the risk of undercooked food, and improving the user experience.

[0053] In one specific implementation, such as Figure 3 As shown, the distance L between the center B of the heating element 2 and the center A of the disk 1 is greater than 2mm. Specifically, L can be 2.1mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, or other values ​​greater than 2mm. It should be noted that the above values ​​are only illustrative examples and are not a limitation on the maximum value of L. It can be understood that the maximum value of L can be greater than 5mm.

[0054] Furthermore, it is understandable that when the heating element 2 is installed on the plate body 1, the outer edge of the heating element 2 usually does not exceed the range of the plate body 1. Therefore, the maximum value of L is mainly limited by the size of the plate body 1. In actual products, the specific value of L can be adjusted according to the size of the plate body 1.

[0055] In this embodiment, when L is greater than 2mm, it can ensure that the farthest distance r between the center A of the plate body 1 and the width center of the heating part 21 on the radial X of the plate body 1 is moderate, so as to ensure that the food in the pot body 4 has a good tumbling effect, further improving the heating uniformity of the food, thereby further reducing the risk of the food being undercooked.

[0056] In one specific implementation, such as Figure 3 As shown, the width W of the heating part 21 is 11mm to 17mm. Specifically, W can be 11mm, 12mm, 13mm, 14mm, 15mm, 16mm or 17mm, or other values ​​within the above range. This application embodiment does not limit this.

[0057] In this embodiment, when W is too small (e.g., less than 11 mm), the overall volume of the heating element 21 becomes too small, resulting in a small area of ​​the high-temperature region 101 on the plate 1. This leads to a decrease in the uniformity and efficiency of heating the liquid and food in the pot 4 by the heating plate assembly. Furthermore, with the inner diameter of the heating tube 2 remaining constant, a small W also results in a small maximum distance r between the center A of the plate 1 and the width center of the heating element 21 along the radial direction X of the plate 1, thus reducing the tumbling effect of the food. When W is too large (e.g., greater than 17 mm), the overall volume of the heating element 21 becomes too large, increasing the cost and weight of the heating tube 2, and consequently increasing the cost and weight of the heating plate assembly. However, the uniformity and efficiency of heating the liquid and food in the pot 4 by the heating plate assembly are not significantly improved, nor is the tumbling effect of the food significantly enhanced.

[0058] Therefore, when W is 11mm to 17mm, it can improve the heating efficiency of the heating plate assembly, improve the heating uniformity and efficiency of the heating plate assembly for the liquid and food in the pot body 4, and improve the tumbling effect of the food in the pot body 4, while also appropriately reducing the weight and cost of the heating plate assembly.

[0059] In one specific implementation, such as Figure 3 As shown, the outer diameter of the heating tube 2 is 84mm to 120mm. Specifically, R can be 84mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm or 120mm, or other values ​​within the above range. This application embodiment does not limit this.

[0060] In the above embodiments, when the width W of the heating element 21 remains constant, if the outer diameter is too small (e.g., less than 84 mm), the furthest distance r between the center A of the plate body 1 and the center of the width of the heating element 21 in the radial direction X of the plate body 1 will be too small, resulting in a reduced tumbling effect of the food. If the outer diameter is too large (e.g., greater than 120 mm), the size of the plate body 1 will increase, leading to an increase in the cost and weight of the heating plate assembly, but the tumbling effect of the food will not be significantly improved. Therefore, when the outer diameter of the heating tube 2 is between 84 mm and 120 mm, the optimization effect of the heating plate assembly is optimal, ensuring that the tumbling effect of the food inside the pot body 4 is effectively improved, while appropriately reducing the weight and cost of the heating plate assembly.

[0061] In one specific implementation, such as Figure 5 As shown, the plate body 1 includes a plate body 11 and a heat-conducting plate 12. Along the thickness direction Z of the heating plate assembly, one side surface of the heat-conducting plate 12 is fixedly connected to the plate body 11, and the other side surface is fixedly connected to the heating tube 2.

[0062] In this embodiment, the heat-conducting plate 12 is located between the heating tube 2 and the plate body 11. It is used to quickly conduct the heat of the heating tube 2 to the plate body 11, thereby improving the heat transfer efficiency when the heating tube 2 transfers heat to the plate body 11. The heat-conducting plate 12 can conduct heat in the radial direction X of the plate body 11, thereby expanding the heat transfer area between the heating tube 2 and the plate body 11, which is beneficial to improving the heating uniformity of the heating plate assembly for the liquid and food in the pot body 4.

[0063] The main body 11 can be made of steel to give it good high temperature resistance and corrosion resistance, and the heat-conducting plate 12 can be made of aluminum to give it good thermal conductivity.

[0064] In one specific implementation, such as Figure 5 As shown, the thickness H1 of the disk body 11 is 0.3mm to 1mm. Specifically, H1 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm, or other values ​​within the above range. This application embodiment does not limit this.

[0065] When H1 is too small (e.g., less than 0.3 mm), the main body 11 is too thin, resulting in insufficient structural strength and affecting the stability and reliability of the heating plate assembly. When H1 is too large (e.g., greater than 1 mm), the main body 11 is too thick, reducing its thermal conductivity. The main body 11 will conduct heat along its radial direction X, causing heat loss and reducing the heating efficiency of the heating plate assembly. This also increases the cost of the main body 11. Therefore, when H1 is between 0.3 mm and 1 mm, it ensures sufficient structural strength for the heating plate assembly while reducing lateral heat dissipation from the main body 11. This improves the heating efficiency of the heating plate assembly and helps to appropriately reduce its cost.

[0066] In one specific implementation, such as Figure 5 As shown, the thickness H2 of the heat-conducting plate 12 is 1.2mm to 3mm. Specifically, H2 can be 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm or 3mm, or other values ​​within the above range. This application embodiment does not limit this.

[0067] When H2 is too small (e.g., less than 1.2 mm), the heat-conducting plate 12 is too thin, resulting in insufficient structural strength and affecting the stability and reliability of the heating plate assembly. When H2 is too large (e.g., greater than 3 mm), the heat-conducting plate 12 is too thick, reducing its heat conduction effect. The heat-conducting plate 12 will conduct heat along its radial direction X, causing heat loss and reducing the heating efficiency of the heating plate assembly. It also increases the cost of the heat-conducting plate 12. Therefore, when H2 is between 1.2 mm and 3 mm, it ensures sufficient structural strength for the heating plate assembly while reducing the lateral heat dissipation of the heat-conducting plate 12. This helps improve the heating efficiency of the heating plate assembly and appropriately reduce its cost.

[0068] In one specific embodiment, the kettle body 4 can be a bottom-opening structure. When the plate body 1 is fixedly connected to the kettle body 4, the plate body 11 can serve as the bottom of the kettle body 4, forming a cavity for holding liquid and food together with the kettle body 4. That is, the plate body 11 can directly contact the liquid and food inside the kettle body 4, which is beneficial to improving the heat conduction effect of the heating plate assembly, thereby improving the heating efficiency of the heating plate assembly. Specifically, as shown... Figure 2 As shown, a receiving groove 13 can be provided on the main body 11 of the tray. At least a portion of the bottom of the pot body 4 extends into the receiving groove 13 and is fixedly connected to the receiving groove 13. This connection structure can increase the connection area between the pot body 4 and the main body 11 of the tray, which is beneficial to improving the connection stability between the pot body 4 and the main body 11 of the tray. Moreover, the receiving groove 13 can limit the pot body 4 along the radial direction X, which is beneficial to improving the installation reliability and stability of the pot body 4.

[0069] The bottom of the pot body 4 can be fixedly connected to the receiving groove 13 by adhesive.

[0070] In one specific implementation, such as Figure 1 and Figure 2 As shown, the heating plate assembly also includes a thermostat 3, which is electrically connected to the connecting part 22. The thermostat 3 can be used to control the opening and closing of the heating element 2 and to adjust the heating temperature of the heating element 2, thereby realizing intelligent temperature control and anti-dry-burning function of the liquid heating container. The thermostat 3 is installed on the plate body 1, specifically by fixing it to the heat-conducting plate 12 with screws. Figure 6 As shown, the heating element 2 can be arranged around the circumference of the temperature controller 3 to achieve the integration of the heating plate assembly, which helps to reduce the overall volume of the heating plate assembly and achieve the effect of saving internal space of the liquid heating container.

[0071] In addition, such as Figure 2 As shown, the liquid heating container also includes a bottom cover 5. The bottom cover 5 can be fixedly connected to the thermostat 3 and the heat-conducting plate 12 by screws, so that the bottom cover 5 can be assembled with the heating plate assembly and the body 4, and the installation reliability of the bottom cover 5 can be improved. The bottom cover 5 and the plate 1 together form a storage space, in which other electrical components of the liquid heating container are installed. The bottom cover 5 can protect the electrical components and play a role in dustproofing and waterproofing.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
