Those skilled in the art can understand the specific outline of the above terms in the present invention according to specific circumstances.
[0038] 1 to 12, a cooking utensil 10 and a heating control method for the cooking utensil 10 according to an embodiment of the present invention will be described in detail below.
[0039] As shown in FIGS. 1-2, 4 and 6, a cooking utensil 10 according to an embodiment of the present invention includes a pot body 1, a pot lid 2 and a temperature measuring device 3.
[0040] The cooking appliance 10 may be an electric rice cooker, a pressure cooker, or the like.
[0041] As shown in FIG. 1 , a pot lid 2 is attached to a pot body 1, forming a storage space within the pot body 1. The pot lid 2 can be in an open state, exposing the storage space and allowing a user to perform related operations within the storage space, such as placing ingredients in the storage space or serving rice from the storage space to the outside. The pot lid 2 can also be in a closed state, closing the storage space. In some embodiments, the pot lid 2 and the pot body 1 are removably connected, allowing a user to expose the storage space by separating the pot lid 2 from the pot body 1. In other embodiments, the pot lid 2 and the pot body 1 can be connected by a hinge, allowing a user to expose the storage space by rotating the pot lid 2.
[0042] As shown in FIG. 1 , the pot lid 2 has an overflow prevention plate 21, which is provided with steam holes 22. During cooking, steam in the storage space can reach the pot lid 2 through the steam holes 22 and can then be discharged through the pot lid 2, thereby reducing the pressure intensity in the storage space and preventing the juice from spilling. A sealing ring 4 and a sealing ring 5 may be provided at the connection between the overflow prevention plate 21 and the pot lid 2. The sealing ring 5 seals the edge of the overflow prevention plate 21 to the pot lid 2, and the sealing ring 4 is used to press the sealing ring 5 against the overflow prevention plate 21. In some embodiments, the overflow prevention plate 21 is removable from the pot lid 2, which makes it easy to clean the area between the overflow prevention plate 21 and the pot lid 2 and to perform maintenance on the components in that area.
[0043] As shown in Figures 1-2, 4 and 6, the temperature measuring device 3 is provided on the pot lid 2, with at least a portion of the temperature measuring device 3 being provided in the area between the overflow prevention plate 21 and the pot lid 2. In this way, when the pot lid 2 is opened, the temperature measuring device 3 is at least partially hidden behind the overflow prevention plate 21 (i.e., the side of the overflow prevention plate 21 facing the pot lid 2), so that the entire pot lid 2 is relatively beautiful and juices in the pot body 1 are less likely to splash onto the temperature measuring device 3. When the entire temperature measuring device 3 is provided in the area between the overflow prevention plate 21 and the pot lid 2, the entire temperature measuring device 3 is hidden behind the overflow prevention plate 21.
[0044] As shown in Figures 3 and 5, the temperature measuring device 3 may be equipped with a temperature measuring unit 31, which is installed to detect the steam temperature in the pot body 1 and the temperature of the overflow prevention plate 21.
[0045] It is important to explain that the "and" in "The temperature measuring unit 31 is installed to detect the steam temperature inside the pot body 1 and the temperature of the overflow prevention plate 21" does not necessarily mean simultaneous, but indicates that the temperature measuring unit 31 has the ability to detect the steam temperature inside the pot body 1 and the ability to detect the temperature of the overflow prevention plate 21. It is possible to detect the steam temperature inside the pot body 1 at one time period and the temperature of the overflow prevention plate 21 at another time period, or it is possible to detect the steam temperature inside the pot body 1 and the temperature of the overflow prevention plate 21 at the same time, and is not limited to this.
[0046] In some embodiments, a first heating device may be provided in the pot body 1 and a second heating device may be provided in the pot lid 2, and when the first heating device is operated, the pot body 1 can be heated, thereby heating the ingredients in the storage space, and when the second heating device is operated, the pot body 1 can be indirectly heated, thereby heating the ingredients in the storage space.
[0047] In some embodiments, when the cooking function of the cooking appliance 10 is turned on, the first heating device first turns on heating, the temperature measuring unit 31 obtains the steam temperature in the pot body 1, and when the steam temperature in the pot body 1 reaches a first preset temperature, the second heating device is further controlled to turn on heating, the temperature measuring unit 31 obtains the temperature of the overflow prevention plate 21, and controls the second heating device according to the temperature of the overflow prevention plate 21. Optionally, the first preset temperature may be the boiling temperature of the soup in the pot body 1.
[0048] The cooking utensil 10 according to an embodiment of the present invention is provided with a temperature measuring device 3 having a temperature measuring unit 31, and the temperature measuring unit 31 is arranged to detect the steam temperature in the pot body 1 and the temperature of the overflow prevention plate 21, so that the heating device of the pot lid 2 can be controlled according to the temperature of the overflow prevention plate 21, which helps to improve the accuracy of control.
[0049] In some embodiments of the present invention, as shown in Figures 2-5, the temperature measuring device 3 is stored within the pot lid 2 so that it does not extend beyond the overflow prevention plate 21. In this way, the temperature measuring device 3 is entirely hidden behind the overflow prevention plate 21. When the pot lid 2 is opened, the entire pot lid 2 looks beautiful and the juice in the pot body 1 is prevented from splashing onto the temperature measuring device 3.
[0050] In some embodiments of the present invention, as shown in Figures 3 and 5, the temperature measuring device 3 may further include a heat-conducting cover 33, the temperature measuring unit 31 being located within the heat-conducting cover 33, which can physically protect the temperature measuring device 3, and the temperature measuring unit 31 sensing the temperature by contacting the heat-conducting cover 33. The heat-conducting cover 33 is placed in close contact with the surface of the overflow prevention plate 21 opposite the pot body 1. In this way, the heat-conducting cover 33 does not extend into the pot body 1, and the heat-conducting cover 33 can transmit the temperature of the overflow prevention plate 21 to the temperature measuring unit 31, so that the temperature measuring unit 31 indirectly detects the temperature of the overflow prevention plate 21. A steam through hole 22 is provided in the overflow prevention plate 21, and the steam through hole 22 corresponds to a part of the heat conduction cover 33. In this way, the steam in the pot body 1 can reach the heat conduction cover 33 directly through the steam through hole 22, thereby transferring the heat of the steam to the heat conduction cover 33, and the temperature measuring unit 31 indirectly detects the steam temperature in the pot body 1.
[0051] In some embodiments of the present invention, as shown in Figure 3, the heat conduction cover 33 has a bottom wall, which has a first bottom wall portion 331, which is used to fit with the temperature measuring unit 31, which can contact the first bottom wall portion 331 and sense the temperature of the first bottom wall portion 331. The steam through hole 22 faces the first bottom wall portion 331. In this way, steam can directly reach the first bottom wall portion 331 through the steam through hole 22, so that the temperature measuring unit 31 fitting with the first bottom wall portion 331 can accurately detect the steam temperature inside the pot.
[0052] Since the area of the steam through holes 22 is smaller than the area of the bottom wall of the heat conduction cover 33, the heat conduction cover 33 can be prevented from falling into the pot body 1 through the steam through holes 22.
[0053] In some embodiments of the present invention, as shown in Figures 3 and 5, the temperature measuring device 3 may further include a mounting portion 34 and a positioning portion 35, and the heat conducting cover 33 is fitted to the lower end of the mounting portion 34. A mounting through-hole 341 is provided in the mounting portion 34, and the temperature measuring portion 31 is mounted in the mounting through-hole 341, which can position the temperature measuring portion 31 and ensure accurate positioning. The positioning portion 35 is attached to the mounting portion 34 and positioned and fitted to the pot lid 2, restricting the mounting direction of the temperature measuring device 3 and aligning the temperature measuring portion 31 with the steam through-hole 22. In this way, steam reaches the heat conducting cover 33 through the steam through-hole 22 and then transfers heat to the temperature measuring portion 31 behind the heat conducting cover 33. Specifically, as shown in Figures 1 and 5, the positioning part 35 has a limit baffle 351, which is suitable for positioning and fitting into a positioning structure (such as a locking groove) on the pot lid 2, so that the relative position of the temperature measuring device 3 and the pot lid 2 is accurate, the temperature measuring part 31 faces the steam through hole 22, and the steam temperature can be quickly transmitted by the temperature measuring part 31, which reduces the delay in temperature sensing and helps to improve the measurement accuracy of the temperature measuring part 31 for the steam temperature in the pot body 1.
[0054] In some embodiments of the present invention, as shown in Figures 3 and 5, the temperature measuring device 3 may further include a compression spring 36, which is arranged between the mounting portion 34 and the pot lid 2 and is used to apply elastic force to the mounting portion 34 toward the overflow prevention plate 21 so as to bring the heat conduction cover 33 into sufficient close contact with the overflow prevention plate 21.
[0055] In some embodiments of the present invention, as shown in Figures 6-9, the temperature measuring unit 31 may include a steam temperature measuring unit 311 and an overflow prevention plate temperature measuring unit 312, where the steam temperature measuring unit 311 is used to measure the steam temperature in the pot body 1, and the overflow prevention plate temperature measuring unit 312 is used to measure the temperature of the overflow prevention plate 21.
[0056] In some embodiments of the present invention, as shown in Figures 6-9, steam temperature measuring unit 311 extends at least partially into pot body 1 relative to overflow plate 21. In this manner, steam temperature measuring unit 311 is at least partially immersed in the steam atmosphere within pot body 1, and the steam within pot body 1 can directly contact steam temperature measuring unit 311, which helps improve the accuracy of detection of steam by steam temperature measuring unit 311. Overflow plate temperature measuring unit 312 is housed within pot lid 2. In this manner, overflow plate temperature measuring unit 312 directly senses the temperature of overflow plate 21, while at the same time preventing steam from coming into contact with overflow plate temperature measuring unit 312, thereby preventing the steam temperature from interfering with the temperature sensing result of overflow plate temperature measuring unit 312.
[0057] In some embodiments of the present invention, as shown in FIGS. 7 and 8 , temperature measuring device 3 may further include a heat-conducting cover 33, which can physically protect temperature measuring device 3. Heat-conducting cover 33 includes a cover body 333 and a protrusion 334. Protrusion 334 protrudes from the bottom wall of cover body 333 toward pot body 1. Protrusion 334 extends into pot body 1 through steam through-hole 22 in spill prevention plate 21. Steam temperature measuring portion 311 is at least partially disposed within protrusion 334. This allows steam temperature measuring portion 311 to at least partially extend into pot body 1, allowing steam within pot body 1 to directly contact protrusion 334, allowing steam temperature measuring portion 311 to measure the temperature of protrusion 334, thereby achieving indirect temperature measurement of steam by steam temperature measuring portion 311. Providing protrusion 334 helps improve the accuracy of detection of steam by steam temperature measuring portion 311.
[0058] In some embodiments of the present invention, as shown in Figures 7-9, an annular bottom wall portion 331 is formed on the bottom wall of the cover body 333, and the annular bottom wall portion 331 is arranged to surround the protrusion 334, and the overflow prevention plate temperature measuring portion 312 is fitted into the annular bottom wall portion 331 to sense the temperature.
[0059] 7-9 , the temperature measuring device 3 may further include a mounting portion 34, and the cover body 333 of the heat conduction cover 33 is fitted into the lower end of the mounting portion 34. A mounting through-hole 341 is provided in the mounting portion 34, and the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312 are both mounted in the mounting through-hole 341. The portion of the steam temperature measuring portion 311 extending from the corresponding mounting through-hole 341 is inserted into the protrusion 334. The mounting through-hole 341 allows the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312 to be positioned, ensuring the accurate positioning of the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32. Specifically, the mounting through hole 341 may have a first mounting through hole 341 and a second mounting through hole 341, the steam temperature measuring unit 311 is mounted in the first mounting through hole 341, and the overflow prevention plate temperature measuring unit 312 is mounted in the second mounting through hole 341, thereby reducing mutual interference between the steam temperature measuring unit 311 and the overflow prevention plate temperature measuring unit 312.
[0060] The temperature measuring device 3 may further include a positioning portion 35, which is attached to the mounting portion 34 and is positioned and fitted to the pot lid 2 to restrict the mounting direction of the temperature measuring device 3 and align the protrusion 334 with the steam through hole 22. In this way, after the steam reaches the protrusion 334, the heat can be transferred to the steam temperature measuring portion 311 behind the protrusion 334. Specifically, as shown in Figures 1 and 9, the positioning portion 35 has a limit baffle 351, which is suitable for being positioned and fitted to a positioning structure (e.g., a locking groove) on the pot lid 2, thereby realizing the accuracy of the relative positioning of the temperature measuring device 3 and the pot lid 2, and the steam temperature measuring portion 311 facing the steam through hole 22, which helps to improve the measurement accuracy of the steam temperature measuring portion 311 relative to the steam temperature in the pot body 1.
[0061] In some embodiments of the present invention, as shown in Figures 7-9, the temperature measuring device 3 may further include a compression spring 36, which is arranged between the mounting portion 34 and the pot lid 2 and is used to apply a resilient force to the mounting portion 34 toward the overflow prevention plate 21 so as to bring the annular bottom wall portion 331 of the heat conduction cover 33 into sufficiently tight contact with the overflow prevention plate 21.
[0062] In some embodiments of the present invention, as shown in Figures 3, 5, and 7-9, the temperature measuring device 3 may further include a temperature controller 32, which is fitted with the overflow plate 21 and cuts off after the temperature of the overflow plate 21 exceeds a threshold, thereby improving the safety of use of the cooking utensil 10. In some embodiments of the present invention, as shown in Figures 2-5 and 7-9, the temperature controller 32 is housed within the pot lid 2 so as not to extend beyond the overflow plate 21. In this way, the temperature controller 32 is hidden behind the overflow plate 21, and when the pot lid 2 is opened, the entire pot lid 2 looks beautiful and the juices in the pot body 1 are prevented from splashing onto the temperature controller 32.
[0063] In some embodiments, the temperature controller 32 may be a fuse, and after the temperature of the overflow plate 21 exceeds a threshold, the temperature controller 32 blows out and the second heating device is disconnected.
[0064] In some embodiments of the present invention, the temperature measuring device 3 comprises a temperature measuring part 31 and a temperature controller 32, the temperature controller 32 can be in direct contact with the overflow prevention plate 21, the temperature controller 32 can quickly sense the temperature of the overflow prevention plate 21, and when the temperature of the overflow prevention plate 21 reaches a threshold value, the temperature controller 32 plays the role of meltdown protection.
[0065] In some embodiments of the present invention, as shown in Figures 3, 5, and 7-9, the temperature measuring device 3 may further include a temperature controller 32. The temperature controller 32 is fitted to the overflow plate 21 and disconnects when the temperature of the overflow plate 21 exceeds a threshold value. The temperature controller 32 is located within the heat conductive cover 33 and senses the temperature by contacting the heat conductive cover 33. In the embodiment shown in Figures 3 and 5, the heat conductive cover 33 is placed in close contact with the surface of the overflow plate 21 opposite the pot body 1. In this way, the temperature controller 32 does not extend into the pot body 1, and the heat conductive cover 33 can transmit the temperature of the overflow plate 21 to the temperature controller 32, allowing the temperature controller 32 to indirectly detect the temperature of the overflow plate 21. 7-9, the thermal conduction cover 33 has a cover body 333 and a protrusion 334. The bottom wall of the cover body 333 is formed with an annular bottom wall portion 331, which is arranged to surround the protrusion 334. The overflow prevention plate temperature measuring portion 312 and the temperature controller 32 are arranged symmetrically in the radial direction with respect to the protrusion 334, and both the overflow prevention plate temperature measuring portion 312 and the temperature controller 32 are fitted into the annular bottom wall portion 331 to sense the temperatures. In this way, the overflow prevention plate temperature measuring portion 312 is far from the temperature controller 32, so that mutual interference can be avoided.
[0066] The thermally conductive cover 33 has a second bottom wall portion 332, which is used to fit with the temperature controller 32, and the temperature controller 32 can contact the second bottom wall portion 332 and senses the temperature of the second bottom wall portion 332. Since the steam through-holes 22 are offset from the second bottom wall portion 332, there is little interference of the steam temperature with the temperature controller 32 fitted with the second bottom wall portion 332.
[0067] In some embodiments of the present invention, as shown in FIG. 3 , the thermally conductive cover 33 has a bottom wall, the bottom wall having a first bottom wall portion 331 and a second bottom wall portion 332, the first bottom wall portion 331 is used to mate with the temperature measuring unit 31, the second bottom wall portion 332 is used to mate with the temperature controller 32, the temperature measuring unit 31 can contact the first bottom wall portion 331 and sense the temperature of the first bottom wall portion 331, and the temperature controller 32 can contact the second bottom wall portion 332 and sense the temperature of the second bottom wall portion 332. The steam through hole 22 faces the first bottom wall portion 331, and by doing so, steam reaches the first bottom wall portion 331 directly through the steam through hole 22, allowing the temperature measuring unit 31 that fits into the first bottom wall portion 331 to accurately detect the steam temperature inside the pot.Furthermore, because the steam through hole 22 is offset from the second bottom wall portion 332, there is little interference of the steam temperature with the temperature controller 32 that fits into the second bottom wall portion 332.
[0068] In some embodiments of the present invention, the equivalent diameter of the first bottom wall portion 331 is smaller than the equivalent diameter of the second bottom wall portion 332, thereby ensuring a larger area for the second bottom wall portion 332 and allowing for a larger contact area between the temperature controller 32 and the second bottom wall portion 332. This helps improve the safety of the cookware 10 since the temperature controller 32 is prone to melting at high temperatures. When the first bottom wall portion 331 and the second bottom wall portion 332 are circular, the equivalent diameter refers to their diameters, i.e., the diameter of the first bottom wall portion 331 is smaller than the diameter of the second bottom wall portion 332. When the first bottom wall portion 331 and the second bottom wall portion 332 are triangular, the equivalent diameter refers to the diameter of a circle where the three vertices of the triangle are located. When the first bottom wall portion 331 and the second bottom wall portion 332 are polygonal, the equivalent diameter refers to the length of the longest diagonal. In other words, the equivalent diameter refers to the maximum distance between any two points on the portion.
[0069] 3 and 5, the temperature measuring device 3 may further include a mounting portion 34 and a positioning portion 35, and the thermally conductive cover 33 may be fitted to the lower end of the mounting portion 34. A mounting through-hole 341 may be provided in the mounting portion 34, and the temperature measuring portion 31 and the temperature controller 32 may be mounted in the mounting through-hole 341. The mounting through-hole 341 may position the temperature measuring portion 31 and the temperature controller 32, ensuring accurate positioning of the temperature measuring portion 31 and the temperature controller 32. Specifically, the mounting through-hole 341 may include a first mounting through-hole 341 and a second mounting through-hole 341, and the temperature measuring portion 31 may be mounted in the first mounting through-hole 341, and the temperature controller 32 may be mounted in the second mounting through-hole 341, thereby reducing mutual interference between the temperature measuring portion 31 and the temperature controller 32.
[0070] 7-9 , the temperature measuring device 3 may further include a mounting portion 34, and the cover body 333 of the heat conduction cover 33 is fitted into the lower end of the mounting portion 34. A mounting through-hole 341 is provided in the mounting portion 34, and the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32 are all mounted in the mounting through-hole 341, and the portion of the steam temperature measuring portion 311 extending from the corresponding mounting through-hole 341 is inserted into the protrusion 334. The mounting through-hole 341 allows the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32 to be positioned, ensuring that the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32 are accurately positioned. Specifically, the mounting through-holes 341 may include a first mounting through-hole 341, a second mounting through-hole 341, and a third mounting through-hole 341, with the steam temperature measuring unit 311 mounted in the first mounting through-hole 341, the overflow prevention plate temperature measuring unit 312 mounted in the second mounting through-hole 341, and the temperature controller 32 mounted in the third mounting through-hole 341. In this way, mutual interference between the steam temperature measuring unit 311 and the overflow prevention plate temperature measuring unit 312 can be reduced.
[0071] A cooking utensil according to an embodiment of the present invention comprises a pot body, a pot lid, a temperature measuring device, a first heating device, and a second heating device.
[0072] The cooking appliance may be an electric rice cooker, a pressure cooker, or the like. A pot lid is attached to the pot body, forming a storage space within the pot body. The pot lid can be in an open state, exposing the storage space and allowing a user to perform related operations within the storage space, such as placing ingredients in the storage space or serving rice from the storage space to the outside. The pot lid can also be in a closed state, enclosing the storage space. In some embodiments, the pot lid and the pot body are removably connected, allowing a user to expose the storage space by separating the pot lid and the pot body. In other embodiments, the pot lid and the pot body can be connected by a hinge, allowing a user to expose the storage space by rotating the pot lid.
[0073] The pot lid has an overflow prevention plate with steam holes formed in the overflow prevention plate, so that during cooking, steam in the storage space can reach the pot lid through the steam holes and can then be discharged through the pot lid, preventing juices from overflowing. A sealing ring and a sealing ring can also be provided at the connection between the overflow prevention plate and the pot lid, with the sealing ring sealing the edge of the overflow prevention plate to the pot lid and the sealing ring pressing the sealing ring against the overflow prevention plate. In some embodiments, the overflow prevention plate is removable from the pot lid, making it convenient to clean the area between the overflow prevention plate and the pot lid and to perform maintenance on parts in that area.
[0074] The temperature measuring device is provided on the pot lid, with at least a portion of the temperature measuring device located within the area between the overflow prevention plate and the pot lid. In this manner, when the lid is opened, the temperature measuring device is at least partially hidden behind the overflow prevention plate (i.e., the side of the overflow prevention plate facing the lid), making the entire pot lid relatively aesthetically pleasing and preventing juices from spilling onto the temperature measuring device. When the temperature measuring device is entirely located within the area between the overflow prevention plate and the pot lid, the entire temperature measuring device is hidden behind the overflow prevention plate. The temperature measuring device includes a temperature measuring unit, which is configured to detect the steam temperature within the pot body and the temperature of the overflow prevention plate. It should be noted that the term "and" does not necessarily mean "simultaneously," but rather indicates that the temperature measuring unit has the ability to detect the steam temperature within the pot body and the temperature of the overflow prevention plate. It is possible to detect the steam temperature within the pot body at one time and the temperature of the overflow prevention plate at another time, or it is possible to simultaneously detect the steam temperature within the pot body and the temperature of the overflow prevention plate, without being limited thereto.
[0075] The first heating device is provided corresponding to the pot body and can be provided in the area between the bottom of the pot body and the housing of the cookware, and the second heating device is provided corresponding to the pot lid and can be provided in the area between the pot lid and the spill prevention plate. When the first heating device is operated, it can raise the temperature of the pot body, thereby heating the ingredients in the storage space, and when the second heating device is operated, it can raise the temperature of the pot body, thereby heating the ingredients in the storage space.
[0076] FIG. 10 is a flowchart of a method for controlling heating of a cooking appliance, and the method for controlling heating of a cooking appliance according to an embodiment of the second aspect of the present invention may include the following steps.
[0077] S1: When the cooking function of the cooking appliance is turned on, the first heating device is controlled to turn on heating, and the temperature measuring unit acquires the steam temperature in the pot body.
[0078] In one embodiment of the present invention, the cooking appliance includes a controller, and when the cooking appliance turns on the cooking function, the controller controls the first heating device to turn on heating; the temperature measuring unit obtains the steam temperature in the pot body and then transmits the steam temperature value to the controller; the controller can control the first heating device according to the steam temperature value; and the controller can correspondingly adjust the heating power of the first heating device according to the steam temperature value. In this step, the temperature measuring unit can only obtain the steam temperature in the pot body.
[0079] S2: When the steam temperature in the pot body reaches the first preset temperature, the second heating device is controlled to turn on, and the temperature measuring unit measures the temperature of the overflow prevention plate, and controls the second heating device according to the temperature of the overflow prevention plate. In this step, the temperature measuring unit can only measure the temperature of the overflow prevention plate.
[0080] In other words, the cooking process is divided into two stages. In the first stage, the first heating device turns on the heating and the temperature measuring unit measures the steam temperature inside the pot body. In the second stage, the second heating device turns on the heating and the temperature measuring unit measures the temperature of the overflow prevention plate. The second heating device inside the pot lid heats the pot body and controls the second heating device according to the temperature of the overflow prevention plate. In other words, the control of the second heating device depends directly on the temperature of the overflow prevention plate, not the steam temperature, which makes the control of the second heating device more accurate. At the same time, the second heating device participates in heating operations in certain cases, helping to meet various cooking needs of the cookware.
[0081] In one embodiment of the present invention, the cooking appliance is equipped with a controller, and when the steam temperature in the pot body reaches a first preset temperature, the controller controls the second heating device to turn on heating, and the temperature measuring unit obtains the temperature of the overflow prevention plate and then transmits the overflow prevention plate temperature value to the controller, and the controller further controls the heating power of the second heating device according to the temperature of the overflow prevention plate.
[0082] A heating control method for a cooking utensil according to an embodiment of the present invention acquires the steam temperature in the pot body by a temperature measuring unit, and controls the second heating device to turn on heating when the steam temperature in the pot body reaches a first preset temperature; further, acquires the temperature of the overflow prevention plate by the temperature measuring unit, and controls the second heating device according to the temperature of the overflow prevention plate, thereby making the control of the second heating device more accurate.
[0083] In some embodiments of the present invention, when the steam temperature in the pot body reaches a first preset temperature, the heating control method for the cooking utensil may include determining cooking information for the cooking utensil, matching a corresponding cooking curve according to the cooking information, and controlling the first heating device and the second heating device according to the cooking curve.
[0084] Specifically, different cooking information has different cooking curves, and after determining the cooking information of the cooking appliance, the first heating device and the second heating device can be controlled according to the corresponding cooking curves that match the cooking information, for example, controlling the operating time length, power, etc. of the first heating device and the second heating device.
[0085] In some embodiments of the present invention, the cooking information includes cooking types, which may be rice, porridge, soup, short ribs, chicken, beans, etc. The step of controlling the second heating device according to the temperature of the overflow prevention plate includes steps S21 and S22. In step S21, the target temperature of the pot lid is determined according to the cooking type. Different cooking types have different target temperatures of the pot lid, and after the user selects the cooking type, the controller adjusts the target temperature of the pot lid accordingly. In S22, the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid is determined, and the heating power of the second heating device is adjusted according to the temperature difference so that the temperature of the overflow prevention plate is adapted to the target temperature of the pot lid.
[0086] Specifically, when the temperature of the overflow prevention plate is lower than the target temperature of the pot lid and the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid is large, the controller can increase the heating power of the second heating device, thereby accelerating the reduction of the temperature difference.When the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid is small, the controller can appropriately reduce the heating power of the second heating device, preventing the temperature of the overflow prevention plate from exceeding the target temperature of the pot lid and reducing the power consumption of the cookware.
[0087] In a specific embodiment of the present invention, as shown in Figure 11, after starting cooking, the first heating device is turned on and the second heating device is turned off, and the temperature measuring unit detects the steam temperature inside the pot body. When the temperature measuring unit detects that the steam temperature has reached T11, it determines that boiling has occurred, and the software determines the current amount of rice and water and matches the preset cooking curve. At the same time, the first and second heating devices are turned on, and the temperature measuring unit begins to detect the temperature of the overflow prevention plate. At the same time, the program determines the cooking type. If the cooking type is rice cooking, the overflow prevention plate temperature is controlled to maintain T12. If the cooking type is porridge or soup cooking, the overflow prevention plate temperature is controlled to maintain T13. If the cooking type is other cooking, the overflow prevention plate temperature is controlled to maintain T14 until the cooking process is completed.
[0088] In some embodiments of the present invention, the temperature measurement unit may include a steam temperature measurement unit and an overflow prevention plate temperature measurement unit, where the steam temperature measurement unit is used to measure the steam temperature in the pot body and the overflow prevention plate temperature measurement unit is used to measure the temperature of the overflow prevention plate. After the first heating device turns on heating, the steam temperature measurement unit obtains the steam temperature in the pot body, and after the second heating device turns on heating, the overflow prevention plate temperature measurement unit obtains the temperature of the overflow prevention plate.
[0089] In some embodiments, the heating power of the first heating device can be adjusted according to the acquired steam temperature value, for example, if the steam temperature value is low, the heating power of the first heating device is increased, thereby accelerating the heating rate of the steam temperature value, and if the steam temperature value is high, the heating power of the first heating device is decreased, thereby reducing the power consumption of the cooking appliance.
[0090] In some embodiments of the present invention, after the second heating device is turned on, the cooking utensil heating control method further includes adjusting the heating power of the first heating device according to the steam temperature in the pot body when the steam temperature in the pot body reaches a second preset temperature. Specifically, the second preset temperature is higher than the first preset temperature, and after the steam temperature in the pot body reaches the second preset temperature, the heating power of the first heating device is reduced to reduce the power consumption of the cooking utensil.
[0091] In some embodiments of the present invention, the step of controlling the second heating device according to the temperature of the overflow prevention plate includes adjusting the heating power of the second heating device according to the temperature of the overflow prevention plate when the temperature of the overflow prevention plate reaches a third preset temperature, making the control more accurate. In some embodiments, when the third preset temperature is lower than the target temperature of the pot lid and the temperature of the overflow prevention plate reaches the third preset temperature, the heating power of the second heating device can be appropriately reduced to save power consumption.
[0092] In one embodiment of the cooking utensil heating control method, as shown in FIG. 12, after cooking begins, the first heating device is first turned on and the second heating device is turned off, and the steam temperature measuring unit detects the steam temperature inside the pot body. When the steam temperature measuring unit detects that the steam temperature has reached T1, the software determines the current amount of rice and water, matches the preset cooking curve, and simultaneously turns on the first and second heating devices. The steam temperature measuring unit continues to monitor the steam temperature, and when the temperature of the steam temperature measuring unit reaches T3, the software controls the heating power of the first heating device to fully boil the rice and water. The overflow plate temperature measuring unit operates independently throughout the cooking process. When the second heating device is turned on, it first operates at the maximum power adjustment rate preset in the software. If the temperature of the overflow plate temperature measuring unit is greater than T2, the heating power adjustment rate of the second heating device is reduced. If the temperature of the overflow plate temperature measuring unit is greater than T, the program begins to control the overflow plate temperature to maintain T4 ± T0 until the entire cooking process is completed.
[0093] In the heating control method of the cooking appliance according to the embodiment of the present invention, the temperature is controlled in stages. When the first preset temperature is the boiling temperature, the steam temperature is detected before boiling through program control, and the boiling time is determined, thereby effectively preventing overflow. By detecting the temperature of the overflow prevention plate after boiling, the temperature of the overflow prevention plate can be controlled in a closed loop, and the second heating device can be accurately adjusted, thereby achieving a better cooking effect.
[0094] A cooking appliance according to an embodiment of the third aspect of the present invention comprises a memory, a processor, and a cooking appliance heating control program stored in the memory and operable by the processor, and when the processor executes the cooking appliance heating control program, the cooking appliance heating control method according to the embodiment of the second aspect described above is realized.
[0095] A cooking appliance according to an embodiment of the third aspect of the present invention has a processor that executes a cooking appliance heating control program stored in a memory, acquires the steam temperature in the pot body using a temperature measuring unit, and controls the second heating device to turn on heating when the steam temperature in the pot body reaches a first preset temperature; further, acquires the temperature of the overflow prevention plate using the temperature measuring unit, and controls the second heating device according to the temperature of the overflow prevention plate, thereby making the control of the second heating device more accurate.
[0096] A computer-readable storage medium according to an embodiment of the fourth aspect of the present invention stores a cooking appliance heating control program, and when the cooking appliance heating control program is executed by a processor, the cooking appliance heating control method according to the embodiment of the second aspect described above is realized.
[0097] When the stored cooking appliance heating control program of a computer-readable storage medium according to an embodiment of the present invention is executed, the temperature measuring unit obtains the steam temperature in the pot body, and when the steam temperature in the pot body reaches a first preset temperature, controls the second heating device to turn on heating; further, the temperature measuring unit obtains the temperature of the overflow prevention plate, and controls the second heating device according to the temperature of the overflow prevention plate, thereby making the control of the second heating device more accurate.
