Description

Technical Field

[0001] This utility model relates to the technical field of kitchen appliances, specifically to a cooking utensil. Background Technology

[0002] In some current cooking appliances, the heating element uses multi-zone coil heating technology, which creates temperature differences in multiple areas of the cooking container to promote convection and ensure even cooking of the food. However, the multi-zone coil structure is located inside the cooking appliance and is not visible to the user. Therefore, the user cannot know the heating characteristics of the device or its operating status at different cooking stages, resulting in a need for improvement in the user experience.

[0003] Therefore, a cooking appliance is needed to at least partially solve the above problems. Utility Model Content

[0004] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, this utility model provides a cooking utensil, the cooking utensil comprising:

[0006] pot body;

[0007] A cooking container, wherein the cooking container is disposed within the pot body;

[0008] A heating device, disposed within the pot body and located below the cooking container, comprises a wire coil base and N wire windings. The N wire windings are disposed on the wire coil base and are spaced apart circumferentially or radially on the wire coil base, such that when the cooking appliance is in operation, a localized temperature difference zone is formed on the inner surface of the cooking container; and

[0009] The panel has a heating indicator area, and the panel has N indicator lights in the heating indicator area, which are used to indicate the working condition of the corresponding wire winding.

[0010] According to this solution, when heating the cooking container, the heating device creates a temperature gradient by making the inner surface of the container hotter in the area corresponding to the wire windings and cooler in the area corresponding to the intervals between the wire windings. This creates a localized temperature difference between the two areas, resulting in a significant temperature gradient. This temperature gradient creates localized uneven heating, which accelerates and intensifies heat convection within the pot, leading to more thorough boiling and churning of the liquid and ingredients, more even heating of the ingredients, and better consistency in the cooking results. Simultaneously, N indicator lights display the working status of each of the N wire windings, allowing users to easily understand the uneven heating characteristics of the heating device and the real-time working status of each wire winding at different cooking stages. Specifically, users can determine the working status of each wire winding through the light information of the indicator lights. For example, the on / off state of the indicator light indicates whether the corresponding wire winding is energized; the color of the indicator light indicates whether the corresponding wire winding is in operation; and the flashing frequency of the indicator light indicates the operating power of the corresponding wire winding.

[0011] Optionally, the layout and shape of the N indicator lights on the heating indicator area are the same as the layout and shape of the N wire windings on the wire reel.

[0012] According to this solution, by arranging the indicator lights in a manner consistent with the layout and shape of the wire windings, users can gain a more detailed understanding of the shape and position of the wire windings within the corresponding heating area of ​​the cooking container.

[0013] Optionally, the indicator light corresponds to the outer contour shape of the wire winding.

[0014] According to this solution, the light signal of the indicator light can reflect the shape of the wire winding, so that the user can understand the shape characteristics of the heating area of ​​the heating device.

[0015] Optionally, the N wire windings are arranged at intervals in the circumferential direction of the wire reel seat, and the N indicator lights are arranged at intervals in the circumferential direction of the heating indicator area.

[0016] According to this solution, when the wire winding heats the cooking container, it creates spaced high-temperature zones on the inner surface of the container in its circumferential direction. This forms a local temperature difference area between the high-temperature zone and the adjacent low-temperature zone, thereby achieving localized uneven heating of the cooking container and promoting heat convection within it. N indicator lights are arranged at intervals in the circumferential direction of the heating indicator area, corresponding to the arrangement of the wire windings, to display the working status of the corresponding wire windings.

[0017] Optionally, the circumferential dimension of the conductor winding in the conductor reel gradually increases radially outward from the conductor reel.

[0018] The indicator light is configured such that its circumferential dimension in the heating indicator area gradually increases radially outward from the heating indicator area.

[0019] According to this solution, the wire winding can be formed into a gradually widening pattern, including fan-shaped and similar designs. Compared to other shapes such as rings, circles, and polygons, the gradually widening wire winding has the structural characteristic of becoming narrower closer to the center of the heating device and wider further away from the center. This characteristic allows the wire winding to cover a larger area at the bottom of the cooking container, ensuring the overall heating efficiency of the heating device, and providing a large coverage area for local temperature difference zones, achieving a large-scale uneven heating and boiling effect. The indicator light is set with the same characteristic shape to reflect this heating feature of the wire winding.

[0020] Optionally, the radial inner ends of the N wire windings are connected, and the radial inner ends of the N indicator lights are connected; or

[0021] Each of the N wire windings is independent, and each of the N indicator lights is independent.

[0022] According to this scheme, N wire windings can be connected in series to control the simultaneous heating of each wire winding, and the indicator lights connected radially at their inner ends can reflect the connection characteristics of the wire windings. Alternatively, the N wire windings can be set independently, so each wire winding can be connected in parallel, and the independent indicator lights can reflect the setting characteristics of the wire windings.

[0023] Optionally, the indicator light is located on the inner side of the panel, and at least the area of ​​the heating indicator area corresponding to the indicator light is set as a visible area, the visible area including N first visible areas corresponding to the positions of the N indicator lights.

[0024] According to this solution, the indicator lights are located on the inside of the panel, which is beneficial for their waterproofing and impact protection. When the indicator lights are located on the inside of the panel, at least the area of ​​the panel corresponding to the indicator lights is made translucent so that the user can see the light from the indicator lights. The visible area includes N first visible areas corresponding to the positions of N indicator lights. The light signal transmitted through each first visible area can reflect the characteristics of the corresponding indicator light, that is, reflect the characteristics of the corresponding wire winding.

[0025] Optionally, at least the first visible area and the indicator light correspond to the outer contour shape of the wire winding.

[0026] According to this solution, the first visible area corresponds to the outer contour shape of the wire winding, or both the first visible area and the indicator light correspond to the outer contour shape of the wire winding, so that the shape of the light signal seen by the user is consistent with the outer contour shape of the wire winding, thereby understanding the shape characteristics of the wire winding in the heating area corresponding to the cooking container.

[0027] Optionally, the N wire windings are arranged at intervals in the circumferential direction of the wire reel seat, the N indicator lights are arranged at intervals in the circumferential direction of the heating indicator area, and the N first visible areas are arranged at intervals in the circumferential direction of the heating indicator area.

[0028] According to this solution, when the wire winding heats the cooking container, it creates spaced high-temperature zones on the inner surface of the container in its circumferential direction. This forms a local temperature difference area between the high-temperature zone and the adjacent low-temperature zone, thereby achieving localized uneven heating of the cooking container and promoting heat convection within it. N indicator lights and corresponding N first visible areas are arranged at intervals in the circumferential direction of the heating indicator area, corresponding to the arrangement of the wire winding, to display the working status of the corresponding wire winding.

[0029] Optionally, the circumferential dimension of the conductor winding in the conductor reel gradually increases radially outward from the conductor reel.

[0030] The indicator light and at least the first visible area are configured such that the circumferential dimension of the heating indicator area gradually increases radially outward from the heating indicator area.

[0031] According to this solution, the wire winding can be formed into a gradually widening pattern, including fan-shaped and similar designs. Compared to other shapes such as rings, circles, and polygons, the gradually widening wire winding has the structural characteristic of being narrower closer to the center of the heating device and wider further away from the center. This characteristic allows the wire winding to cover a larger area at the bottom of the cooking container, ensuring the overall heating efficiency of the heating device, and providing a large coverage area for local temperature difference zones, achieving a large-scale uneven heating and boiling effect. Simultaneously, the first visible area matches the outer contour shape of the wire winding, or both the first visible area and the indicator light match the outer contour shape of the wire winding, ensuring that the shape of the light signal seen by the user matches the outer contour shape of the wire winding, thus allowing the user to understand the shape characteristics of the wire winding in the corresponding heating area of ​​the cooking container.

[0032] Optionally, the radial inner ends of the N wire windings are connected, the radial inner ends of the N indicator lights are connected, and the visible area further includes a second visible area located in the middle, with the radial inner ends of the N first visible areas connected to the second visible area. According to this scheme, the wire windings can be connected in series with wires, and the N first visible areas are connected to the second visible area, making the shape of the visible area consistent with the shape of the wire windings, thus reflecting the connection characteristics of the wire windings.

[0033] Alternatively, the N wire windings, the N indicator lights, and the N first visible areas are all independent. According to this scheme, the wire windings can be connected in parallel. Correspondingly, the N indicator lights and the N first visible areas are all independent, allowing the user to see N independent light signals that reflect the connection characteristics of the wire windings.

[0034] Optionally, the wire winding is formed by winding wires, and the indicator light is formed by winding a lamp tube. The winding method and shape of the lamp tube are the same as those of the wire winding.

[0035] According to this solution, the indicator light can reflect the winding method and shape of the conductor winding by the winding method and shape of the lamp tube, so that users can obtain more comprehensive and detailed information about the conductor winding.

[0036] Optionally, the N wire windings are formed by winding the same wire, so that the N wire windings are a whole, and the N indicator lights are formed by winding the same lamp tube, so that the N indicator lights are a whole.

[0037] According to this scheme, the N wire windings are made of the same wire, making the N wire windings a whole, and the wire winding method is simple. At the same time, the N indicator lights are also made of the same lamp tube, making the N indicator lights a whole, and the lamp tube winding method is simple.

[0038] Alternatively, each of the N wire windings is formed by winding a separate wire, so that the N wire windings are independent, and each of the N indicator lights is formed by winding a separate lamp tube, so that the N indicator lights are independent.

[0039] According to this scheme, each of the N wire windings is formed by winding a separate wire, and each wire winding is independent, allowing for flexible configuration of the connection method between the wire windings. Simultaneously, each of the N indicator lights is formed by winding a separate lamp tube, consistent with the wire windings, and the control method of each indicator light is flexible.

[0040] Optionally, the indicator light is a color-changing light for displaying at least two colors; and / or

[0041] The panel has a groove, and the indicator light is located in the groove.

[0042] According to this solution, the indicator light can reflect the working status of the wire winding in more detail through color changes. The indicator light is positioned within a groove on the inner side of the panel, facilitating its positioning and installation without affecting the arrangement of other components within the cooking appliance. Alternatively, the indicator light can also be positioned within a groove on the outer side of the panel, ensuring a smooth outer surface.

[0043] Optionally, the panel is located on the pot body. Alternatively, the cooking appliance further includes a lid, and the panel is located on the lid. According to this solution, the panel is easy to set up, and the user can easily see the light signal of the indicator light from the pot body or the lid. Attached Figure Description

[0072] It should be noted that the terms “up,” “down,” “front,” “back,” “left,” “right,” “inner,” “outer,” and similar expressions used in this article are for illustrative purposes only and are not intended to be restrictive.

[0073] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0074] like Figures 1 to 3 As shown, this utility model provides a cooking appliance 100, which includes a pot body 10, a cooking container 30, and a heating device 40. The pot body 10 has a cylindrical cooking container storage section. The cooking container 30 can be fixedly installed in the cooking container storage section, or it can be freely placed into or removed from the cooking container storage section for easy cleaning. The cooking container 30 is usually made of metal and has a circular opening on its upper surface for holding materials to be heated, such as rice or soup, for example, the inner pot of a pot. The heating device 40 is located inside the pot body 10 and below the cooking container 30 to heat the cooking container 30.

[0075] The heating device 40 of the cooking appliance 100 can be an electric heating device 40 that uses induction heating, making the cooking appliance 100, for example, a regular rice cooker, an electric stove equipped with a cooking container 30, a pressure cooker, etc., in which case the cooking container 30 is made of a heat-conducting material. Alternatively, the heating device 40 of the cooking appliance 100 can be an electromagnetic heating device 40 such as an induction coil, making the cooking appliance 100 an electromagnetic cooking appliance 100 with electromagnetic heating, such as an IH rice cooker, an IH pressure cooker, etc., in which case the cooking container 30 includes a magnetically conductive material. In addition to the function of cooking rice, the cooking appliance 100 can also have various functions such as cooking porridge.

[0076] like Figure 4As shown, the heating device 40 includes a wire coil base 41 and N wire windings 42, where N is an integer greater than or equal to 2. The N wire windings 42 are disposed on the wire coil base 41, for example, by means of a baffle rib on the side of the wire coil base 41 facing away from the cooking container 30. The N wire windings 42 are spaced apart circumferentially or radially on the wire coil base 41, creating localized temperature difference zones on the inner surface of the cooking container 30 when the heating device 40 is operating. When heating the cooking container 30 using the heating device 40, the inner surface of the cooking container 30 has a higher temperature in the area corresponding to the wire windings 42 and a lower temperature in the area corresponding to the interval between adjacent wire windings 42, thus creating a localized temperature difference zone between the two areas, i.e., generating a significant temperature gradient. This temperature gradient creates localized uneven heating, prompting faster and more intense heat convection within the pot, resulting in more thorough boiling and churning of the liquid and ingredients, more even heating of the ingredients, and better consistency in the cooking process.

[0077] To enhance the user experience, the cooking appliance 100 also includes a panel 50. The panel 50 has a heating indicator area A, and N indicator lights 51 are provided in the area of ​​the heating indicator area A. The indicator lights 51 indicate the operating status of the corresponding wire winding 42. The indicator lights 51 can be located on the inner or outer side of the panel 50. When the indicator lights 51 are located on the inner side of the panel 50, at least the area corresponding to the indicator light 51 in the heating indicator area A is designated as a visible area S, allowing the light from the indicator lights 51 to pass through. That is, each indicator light 51 corresponds to one wire winding 42, and the light signal of the indicator light 51, or the light signal after passing through the visible area S, indicates the operating status of its corresponding wire winding 42. For example, the heating device 40 includes a wire winding 42 and an indicator light 51. The light signal of the indicator light 51 is used to display the operating status of the wire winding 42 to the user, and the light signal of the indicator light 51 is used to indicate the operating status of the wire winding 42 to the user. Light signals, such as the shape of the light as seen by the user, the color of the light, the flashing frequency and the duration of the intervals, are information that can be received by the user through the light. The operating conditions of the conductor winding 42 include whether the conductor winding 42 is energized, whether the conductor winding 42 is in operation, the power of the conductor winding 42, and other operating status information of the conductor winding 42.

[0078] Therefore, users can intuitively understand the characteristics of uneven heating in multiple local areas of the heating device 40, as well as the real-time working status of each wire winding 42. For example, the on / off state of each indicator light 51 indicates whether the corresponding wire winding 42 is energized, the color of the indicator light 51 indicates whether the corresponding wire winding 42 is working, and the flashing frequency of the indicator light 51 indicates the working power of the corresponding wire winding 42. In other words, the flashing frequency of the indicator light 51 reflects the rolling speed of the food in the cooking container 30.

[0079] The visible area S of panel 50 can be constructed of a transparent material so that the light from indicator light 51 can be seen by the user after passing through. Alternatively, the visible area S of panel 50 can be constructed of a material suitable for switching to a transparent state when powered on, such as frosted glass. Indicator light 51 is a color-changing light used to display at least two colors, thereby reflecting the working status of wire winding 42 to the user through the color of the light. For example, indicator light 51 can light up green and red, with no light when the cooking appliance 100 is not powered on, green light when powered on and in standby mode, and red light when powered on and in operation.

[0080] Optionally, such as Figure 1 and Figure 3 As shown, the cooking appliance 100 also includes a lid 20, which has a shape substantially corresponding to the pot body 10. The lid 20 is closable on the pot body 10; specifically, it is pivotally connected to the pot body 10 via a pivot axis and can freely pivot about the pivot axis between a closed position and an open position relative to the pot body 10, facilitating the closing and opening of the pot body 10. When the lid 20 is closed on the pot body 10, it covers the cooking container 30, forming a cooking space between the lid 20 and the cooking container 30. The lid 20 typically also has a pot rim sealing ring, which can be made of, for example, rubber material, and is positioned between the lid 20 and the cooking container 30 to seal the cooking space when the lid 20 is closed.

[0081] Therefore, the panel 50 can be disposed on the cover 20, for example, on the upper surface of the cover 20, to facilitate user observation of the light signal of the indicator light 51. Specifically, a groove is provided on the inner side of the panel 50, and the indicator light 51 is disposed in the groove (see...). Figure 3 For example, by pasting or snapping. Therefore, the indicator light 51 will not occupy too much space within the cover 20 and affect the placement of other components. Alternatively, the panel 50 can have a groove on its outer side, with the indicator light 51 placed within the groove. The inner side of the panel is the side facing the inside of the cooking appliance, and the outer side of the panel is the side facing the outside of the cooking appliance.

[0082] In some embodiments not shown, the panel 50 may also be located on the cooker body 10, allowing the user to easily observe the light signal of the indicator light 51.

[0083] To ensure that the light signals of the indicator lights 51 more accurately and comprehensively reflect the heating characteristics of the heating device 40, the layout and shape of the N indicator lights 51 on the heating indicator area A are identical to the layout and shape of the N wire windings 42 on the wire reel base 41. In this case, the visible area S can be the area of ​​the heating indicator area A corresponding to the indicator lights 51, or the visible area S can be a larger area including the area corresponding to the indicator lights 51. The layout of the N wire windings 42 on the wire reel base 41 includes the relative positions of each wire winding 42. The shape of the N wire windings 42 on the wire reel base 41 includes the overall outline shape of the N wire windings 42, the outer outline shape of each wire winding 42, and may also include, for example, the winding method of the wires in the wire windings 42. Therefore, the layout of the light signals provided to the user by the N indicator lights 51 can reflect the arrangement of the N wire windings 42, and the shape of the light signal of each indicator light 51 can reflect the shape of each wire winding 42.

[0084] Optionally, the visible area S can be configured to correspond to the outer contour shape of the wire winding 42. Thus, even if the indicator light 51 is not configured to have the same shape as the wire winding 42, the user can still observe a light signal consistent with the outer contour of the wire winding 42 through the visible area S. Specifically, the visible area S is configured to include N first visible areas S1 corresponding to the positions of N indicator lights 51, and the first visible areas S1 correspond to the outer contour shape of the wire winding 42. Preferably, both the first visible areas S1 and the indicator lights 51 are configured to correspond to the outer contour shape of the wire winding 42.

[0085] In one embodiment (not shown), N wire windings 42 are arranged radially spaced apart on the wire reel base 41, and N indicator lights 51 are arranged radially spaced apart on the heating indicator area A. One example is that the wire windings 42 are arranged in a ring, i.e., in a ring around the circumference of the wire reel base 41, and the N wire windings 42 are arranged in a concentric ring array along the radial direction of the wire reel base 41. Correspondingly, the N indicator lights 51 are arranged in a ring around the circumference of the heating indicator area A, and the N indicator lights 51 are arranged in a concentric ring array along the radial direction of the heating indicator area A.

[0086] In another implementation, such as Figures 5 to 9As shown, N wire windings 42 are arranged at intervals in the circumferential direction of the wire reel 41, and N indicator lights 51 are arranged at intervals in the circumferential direction of the heating indicator area A. Further, the size of the wire windings 42 in the circumferential direction of the wire reel 41 gradually increases radially outward from the wire reel 41; for example, each wire winding 42 is generally fan-shaped. Correspondingly, the size of the indicator lights 51 in the circumferential direction of the heating indicator area A gradually increases radially outward from the heating indicator area A. Alternatively, the visible area S includes N first visible areas S1 corresponding to the positions of the N indicator lights 51, the first visible areas S1 being configured such that their size in the circumferential direction of the heating indicator area A gradually increases radially outward from the heating indicator area A. Preferably, both the indicator lights 51 and the first visible areas S1 have their size in the circumferential direction of the heating indicator area A gradually increasing radially outward from the heating indicator area A. Thus, the user can observe that the light signal emitted by the indicator lights 51 is fan-shaped, indicating that the wire windings 42 are heated using fan-shaped wire windings 42.

[0087] Compared to other shapes such as rings, circles, and polygons, the gradually widening wire winding 42 has the structural characteristic of being narrower closer to the bottom center of the cooking container 30 and wider further away from the bottom center of the cooking container 30. This structural characteristic allows the wire winding 42 to cover more of the cooking container 30 area at least at the bottom, and the wire winding 42 has a larger adjustment area for the heat distribution of the cooking container 30, thus covering a larger area of ​​local temperature difference regions and achieving a large-scale uneven heating and boiling effect.

[0088] like Figure 5 As shown, the heating device 40 includes a wire reel holder 41 and six wire windings 42. The six wire windings 42 are arranged at intervals around the circumference of the wire reel holder 41. The dimension of each wire winding 42 in the circumferential direction of the wire reel holder 41 gradually increases outward along the radial direction of the wire reel holder 41, forming a fan-shaped structure. Figure 5 The corresponding indicator light 51 of the heating device 40 shown is as follows: Figure 6 As shown, the heating indicator area A is provided with six indicator lights 51, which are arranged at intervals around the circumference of the heating indicator area A. The size of each indicator light 51 in the circumference of the heating indicator area A gradually increases outward along the radial direction of the wire tray base 41.

[0089] Regarding the connection between the wire windings 42, optionally, N wires are connected in series, thereby enabling unified control of the operating state of the N wire windings 42, such as simultaneously starting or stopping heating. The contour characteristics of the wire windings 42 are reflected in the fact that the radial inner ends of the N wire windings 42 are connected. Correspondingly, the radial inner ends of the N indicator lights 51 are connected, and the visible area S also includes a second visible area S2 located in the middle, with the radial inner ends of the N first visible areas S1 connected to the second visible area S2. This allows for a better demonstration to the user via optical signals of the simultaneous heating characteristic of the wire windings 42 connected in series. Alternatively, the wire windings 42 can be connected in parallel, allowing for flexible heating mode settings and enabling more heating effects. The contour characteristics of the wire windings 42 are reflected in the fact that each of the N wire windings 42 is independent. Correspondingly, each of the N indicator lights 51 is independent, and each of the N first visible areas S1 is also independent. This allows for a better demonstration to the user via optical signals of the parallel connection of the wire windings 42, enabling individual control of their operating state.

[0090] The conductor winding 42 is formed by winding conductors. To reflect the winding method of the conductor winding 42, the indicator light 51 is formed by winding a lamp tube. The winding method and shape of the lamp tube are the same as the winding method and shape of the conductors.

[0091] In terms of the specific winding method of the wires, optionally, N wire windings 42 are formed by winding the same wire, so that the N wire windings 42 form a whole, and N indicator lights 51 are formed by winding the same lamp tube, so that the N indicator lights 51 form a whole. For example... Figure 5 As shown, the six conductor windings 42 are wound together as a whole using the same conductor, and at the same time, as Figure 6 As shown, indicator light 51 is configured to be made up of the same light tubes wound together as a whole.

[0092] Optionally, each of the N wire windings 42 is wound with a separate wire, thus making each of the N wire windings 42 independent; similarly, each of the N indicator lights 51 is wound with a separate lamp tube, thus making each of the N indicator lights 51 independent. Figure 7 As shown, each of the six wire windings 42 is formed by winding a separate wire, and each of the six wire windings 42 is independent. Meanwhile, as... Figure 8 and Figure 9 As shown, each of the six indicator lights 51 is formed by winding a separate lamp tube, so that each of the six indicator lights 51 is independent.

[0093] In controlling the indicator light 51, the display effect of the indicator light 51 can be linked with the heating status of the heating device 40 through program control.

[0094] For example, when the cooking appliance 100 is not powered on, indicator light 51 is off; when powered on and in standby mode, it is green; and when powered on and in operation, it is red / blue. The user observes that all indicator lights 51 are red, and the light signal emitted by indicator lights 51 is a multi-leaf fan shape, indicating that the wire winding 42 uses multi-leaf fan-shaped wires for simultaneous heating.

[0095] For example, when the wire winding 42 is heated at high power, the corresponding indicator light 51 flashes rapidly; when the wire winding 42 is heated at low power, the corresponding indicator light 51 flashes slowly. This demonstrates the characteristics of tumbling and uniform heating. Specifically, when multiple areas of the wire winding 42 are heated in series simultaneously, and the high-power tumbling heating occurs, all indicator lights 51 flash rapidly to reflect the tumbling speed; when the low-power uniform heating occurs, all indicator lights 51 change color or flash slowly. When multiple areas of the wire winding 42 are heated independently, and the high-power tumbling heating occurs, some indicator lights 51 corresponding to the currently heated wire winding 42 flash rapidly to reflect the tumbling speed; when the low-power uniform heating occurs, some indicator lights 51 corresponding to the currently heated wire winding 42 change color or flash slowly.

[0096] The indicator light 51 solution in this design can also combine the display effect of indicator light 51 with the cooking program, so that the different heating states at each stage of cooking can be reflected through the display effect of indicator light 51.

[0097] For example, for multiple series-connected wire windings 42, during the cold-soaking preheating and water absorption stage, the heating device 40 operates at low power. At this time, the indicator light 51 flashes red or blue with a weak brightness and slow flashing intervals of 5-20 seconds; the higher the power, the shorter the flashing interval. During the heating stage, the heating device 40 operates at high power. At this time, the indicator light 51 flashes red with a strong brightness and rapid flashing intervals of 1-10 seconds; the higher the power, the shorter the flashing interval. During the boiling stage, the heating device 40 maintains boiling heating at high power. At this time, the indicator light 51 flashes red with a strong brightness and rapid flashing intervals of 1-5 seconds. During the simmering and heat-keeping stages, the heating device 40 operates at low power intermittently. At this time, the indicator light 51 flashes red or blue with a weak brightness and slow flashing intervals of 5-20 seconds. Of course, the above-mentioned light color and flashing time can be set differently.

[0098] For example, for the six wire windings 42 connected in parallel, each wire winding 42 can start heating and stop heating independently. The corresponding six indicator lights 51 are also designed independently, and each indicator light 51 can light up and flash independently. For ease of explanation later, the six wire windings 42 are numbered wire windings 1-6, and the corresponding six indicator lights 51 are numbered indicator lights 1-6.

[0099] During the cold-soaking preheating and water absorption stages, the wire windings 1-6 are heated and stopped simultaneously, operating at low power. At this time, indicator light 51 illuminates with a red or flashing blue light, and the light brightness is weak. Indicator light 51 flashes slowly with a flashing interval of 5s to 20s. The higher the power, the shorter the flashing interval.

[0100] During the heating phase, the wire windings 1-6 are heated and stopped simultaneously. The heating is done at high power. At this time, indicator lights 1-6 are red and flashing, with a strong brightness. Indicator light 51 flashes rapidly with a flashing interval of 1-10 seconds. The higher the power, the shorter the flashing interval.

[0101] During the first boiling stage, to achieve multi-zone temperature difference-driven convection tumbling, wire windings 1, 3, and 5 are heated simultaneously as one group, and wire windings 2, 4, and 6 are heated simultaneously as another group. The two groups of wire windings 42 are heated intermittently in turn. At this time, indicator lights 1, 3, and 5 illuminate and flash when wire windings 1, 3, and 5 are heated, and indicator lights 2, 4, and 6 illuminate and flash when wire windings 2, 4, and 6 are heated. The lights are very bright, and indicator light 51 flashes rapidly with an interval of 1 to 5 seconds. When wire winding 42 is not heated, the corresponding indicator light 51 is off.

[0102] During the second boiling stage, to achieve clockwise turbulence, wire windings 1, 2, 3, 4, 5, and 6 are heated in a clockwise direction. The corresponding indicator lights 51 illuminate and flash clockwise in sequence (1, 2, 3, 4, 5, 6), with a strong brightness and rapid flashing intervals of 1 to 5 seconds. When wire winding 42 is not heated, the corresponding indicator light 51 remains off.

[0103] During the third boiling stage, to achieve counter-clockwise tumbling, the wire windings 6, 5, 4, 3, 2, and 1 are heated in a counter-clockwise direction. The corresponding indicator lights 51 illuminate and flash counter-clockwise in sequence (6, 5, 4, 3, 2, 1), with a strong brightness and rapid flashing intervals of 1 to 5 seconds. When the wire winding 42 is not heated, the corresponding indicator light 51 is off.

[0104] During the rice cooking and heat preservation stages, to ensure the consistency of the rice at the bottom, the wire windings 1-6 heat up and stop simultaneously, operating at low power. At this time, indicator lights 1-6 flash red or blue lights with a dim brightness, and indicator light 51 flashes slowly with an interval of 5-20 seconds. The higher the power, the shorter the flashing interval.

[0105] When cooking is complete and the cooking appliance is powered on, the light turns green.

[0106] The above is an example of the indicator light 51 being linked to the cooking program. Other lighting methods, lighting colors, and flashing times are also possible.

[0107] According to the cooking appliance 100 of this utility model, users can intuitively understand the uneven heating characteristics of multiple local areas of the heating device 40 and the real-time working status of each wire winding 42 through the light signals of the indicator lights 51 set on the panel 50. The indicator lights 51 provide comprehensive information about the heating device 40, including the shape of the wire winding 42, the wire winding 42 being heated, and the power level, thus improving the user experience.
