Description

Technical Field

[0001] This utility model relates to the field of stew pots, and in particular to an intelligent partitioned three-dimensional heating electric stew pot. Background Technology

[0002] With the fast pace of modern life and increasing emphasis on healthy eating, electric slow cookers, as convenient and efficient cooking tools, have gradually become an important appliance in family kitchens. Traditional electric slow cookers use a single bottom heating method, heating food through simple heat conduction, but this method has significant limitations. First, a single heating mode makes it difficult to achieve precise temperature control in different areas of the pot, resulting in uneven heating of food; some areas may overheat while others fail to reach the ideal temperature, affecting cooking results and taste. Second, traditional electric slow cookers experience significant heat loss during heating, especially the heat carried by steam, which often escapes directly into the environment, wasting energy and increasing cooking costs. These problems not only reduce cooking efficiency but also fail to meet modern people's demands for energy conservation, environmental protection, and refined cooking. Therefore, how to achieve precise zoned temperature control within the pot and how to effectively recover and utilize lost heat have become key issues that urgently need to be addressed in the field of electric slow cooker technology. To address these technical contradictions, a new design is urgently needed that can achieve three-dimensional and differentiated temperature management during heating, while improving energy efficiency, providing users with a more intelligent and energy-saving cooking experience. This demand has driven continuous innovation and development in related technologies to meet the market's requirements for high-quality cooking equipment. Utility Model Content

[0019] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments of this utility model will be described below based on its overall structure. An intelligent partitioned three-dimensional heating electric slow cooker aims to achieve rapid and uniform heating of the ceramic inner pot through three-dimensional heating and intelligent temperature control, while simultaneously improving thermal efficiency.

[0021] For ease of description, the terminology used in this manual is based on the placement of the intelligent partitioned three-dimensional heating electric slow cooker under normal use conditions, such as... Figure 1 As shown, "bottom" refers to the part close to the ground, "top" refers to the part away from the ground, "side wall" refers to the circumferential wall of the outer or inner pot, "inner" refers to the direction close to the center of the electric slow cooker, and "outer" refers to the direction away from the center.

[0022] Reference Figures 1-5This utility model provides an intelligent partitioned three-dimensional heating electric slow cooker, comprising an inner pot 1, an outer pot 2, and a heating component 3. The inner pot 1 is made of ceramic, but can also be made of other common non-metallic materials. The inner pot 1 is placed inside the outer pot 2 and is used to hold food. The outer pot 2 is made of metal, such as stainless steel, and is used to support the inner pot 1 and transfer heat. The heating component 3 includes a heating element 4 disposed at the bottom of the outer pot 2 and an annular heating band 5 surrounding the side of the outer pot 2. The heating element 4 is a circular electric heating plate, fixed to the bottom of the outer pot 2 by bolts, and is used to directly heat the bottom of the outer pot 2. In one embodiment of this utility model, the annular heating band 5 is an annular electric heating device, including at least two heating rings connected in series, with a spacing of at least 5 mm between the heating rings. It is circumferentially attached to the outer surface of the side wall of the outer pot 2, and works in conjunction with the heating element 4 through a controller to achieve three-dimensional heating of the outer pot 2, compensating for the slow heat conduction speed of the ceramic inner pot 1.

[0023] like Figure 1 and Figure 2 As shown, the inner wall of the outer pot 2 is equipped with several temperature sensors 6, forming a temperature control network. The temperature sensors 6 include a bottom sensor group, a side wall sensor group, and a top sensor group. The bottom sensor group is evenly distributed on the inner surface of the bottom of the outer pot 2, for example, arranging four sensors in a circular array, to monitor the temperature distribution at the bottom of the inner pot 1. The side wall sensor group is distributed along the height and circumference of the outer pot 2, for example, setting four sensors in a ring every 5 cm, for a total of 12 sensors in 3 rings, to monitor the temperature at different heights and circumferential positions on the side walls of the outer pot 2. The top sensor group is located at the inner edge of the top of the outer pot 2, for example, 2 sensors, to monitor the temperature of the top area of ​​the inner pot 1. The temperature sensors 6 are electrically connected to the controller via wires. The controller dynamically adjusts the heating power of the heating element 4 and the annular heating strip 5 based on the real-time temperature data of each sensor group, achieving precise temperature control by zone, effectively avoiding local overheating or underheating, and improving heating uniformity.

[0024] Reference Figure 3A heat-conducting regulating ring 7 is provided between the outer pot 2 and the inner pot 1. The heat-conducting regulating ring 7 has a ring-shaped structure, with its outer surface conforming to the inner wall of the outer pot 2 and its inner surface contacting the outer wall of the inner pot 1, used to regulate heat conduction between the inner and outer pots. The heat-conducting regulating ring 7 is made of a shape memory alloy, such as a nickel-titanium alloy, which has the ability to deform with temperature changes. The heat-conducting regulating ring 7 has several regulating cavities 13, for example, 100 regulating cavities 13 evenly distributed along the circumferential and height directions, each with an initial diameter of 1 mm. The regulating cavities 13 are filled with a heat-conducting medium 14, such as liquid gallium or paraffin phase change material. When the temperature rises, the shape memory alloy expands due to heat, the diameter of the regulating cavity 13 increases to 2 mm, and the fluidity of the heat-conducting medium 14 increases, promoting heat transfer; when the temperature decreases, the diameter of the regulating cavity 13 shrinks to 0.5 mm, the fluidity of the heat-conducting medium 14 is restricted, and heat conduction is slowed down. The heat-conducting regulating ring 7 is divided into an upper regulating section, a middle regulating section, and a lower regulating section. The diameter range of the regulating cavity 13 in each section is 0.5-1.5 mm, 0.8-2 mm, and 1-2.5 mm, respectively, to adapt to the heat conduction requirements of different areas of the inner pot 1. By combining the changes in the diameter of the regulating cavity 13 with the flow state of the heat-conducting medium 14, the heat-conducting regulating ring 7 achieves differentiated heat conduction control in different areas of the inner pot 1, significantly improving heating efficiency and uniformity.

[0025] like Figure 4 As shown, the annular heating band 5 is internally equipped with a spiral heat-conducting pipe 11 to enhance the uniformity of heat distribution on the sidewalls. The spiral heat-conducting pipe 11 includes a main heat pipe. The main heat pipe is made of copper and has a diameter of 5-10 mm. It is spirally wound around the inner circumference of the annular heating band 5, with each turn spaced 10 mm apart. Through the main heat pipe, the heat from the annular heating band 5 is evenly transferred to the sidewalls of the outer pot 2, avoiding localized high temperatures and improving the three-dimensional heating effect.

[0026] like Figure 5 As shown, it is a type of heating plate for the bottom of the outer pot, which uses a multi-ringed heating tube. The heating tube is made of copper and has a diameter of 5 mm. The interval between the rings is not equal, but can also be equal.

[0027] like Figure 6 As shown, the bottom of the outer pot 2 is provided with a heat dissipation regulating plate 28 to prevent overheating. The heat dissipation regulating plate 28 is a circular metal plate, which is fixed to the outer side of the bottom of the outer pot 2 by bolts, and has a number of heat dissipation holes 29, for example, 10 heat dissipation holes 29 with a diameter of 5 mm. The number of heat dissipation holes can be set according to requirements and processing technology.

[0028] The controller is an embedded microcontroller, located within the control panel on the outside of the outer pot 2, and electrically connected to the temperature sensor 6, heating element 4, annular heating strip 5, heat-conducting regulating ring 7, flow regulating valve, and temperature regulating valve. The controller uses a preset algorithm to dynamically adjust the power of the heating component 3 and the thermal conductivity of the heat-conducting regulating ring 7 based on real-time data from the temperature sensor 6, achieving intelligent zoned heating and heat management. For example, when the sidewall sensor detects that the upper temperature is too low, the controller increases the power of the annular heating strip 5 and simultaneously adjusts the thermal conductivity of the regulating section of the heat-conducting regulating ring 7 to promote heat transfer upwards. This intelligent control mechanism ensures uniform temperature across all areas of the inner pot 1, optimizing the cooking effect.

[0029] The following is a description of a specific embodiment. Figure 1 As shown, the inner pot 1 is a ceramic pot with a diameter of 20 cm, and the outer pot 2 is a stainless steel pot with a diameter of 22 cm. The inner pot 1 is placed inside the outer pot 2, and a heat-conducting adjustment ring 7 with a thickness of 2 mm is set between them. The heating element 4 is a circular electric heating plate with a power of 800 watts, fixed to the bottom of the outer pot 2. The annular heating band 5 is a ring-shaped heating device with a power of 600 watts, with embedded spiral heat-conducting pipes 11, and the main spiral spacing of the heat-conducting pipes is 3 cm. Twelve temperature sensors 6 are set on the inner wall of the outer pot 2, including four bottom sensors, six side wall sensors, and two top sensors. The controller adjusts the heating power and heat distribution in real time according to the temperature data. During the cooking process, the heating element 4 and the annular heating band 5 heat together, the heat-conducting adjustment ring 7 dynamically adjusts the thermal conductivity according to the temperature, and the heat dissipation adjustment plate 28 prevents the bottom from overheating, ultimately achieving a fast, uniform, and low-energy cooking effect.

[0030] The aforementioned structure, through the synergistic effect of three-dimensional heating, a temperature control network, and thermal conductivity regulation, solves the problems of slow heat conduction and uneven heating in traditional ceramic inner pots, resulting in significant energy-saving effects and practical value. A possible alternative is that the thermal conductivity regulating ring 7 can be made of multi-layered composite materials, with the thermal conductivity adjusted through interlayer sliding.
