Those skilled in the art can understand the specific concepts of the above terms in the present invention according to specific situations.

[0038] Hereinafter, with reference to FIGS. 1-12, the cooking appliance 10 according to an embodiment of the present invention and the heating control method of the cooking appliance 10 will be described in detail.

[0039] As shown in FIGS. 1-2, 4, and 6, the cooking appliance 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, the pot lid 2 is attached to the pot body 1, a storage space is formed inside the pot body 1, the pot lid 2 has an open state, and at this time, the storage space is exposed. The user can perform related operations such as putting ingredients into the storage space or scooping rice from the storage space to the outside within the storage space. The pot lid 2 also has a closed state, and at this time, the storage space is closed. In some embodiments, the pot lid 2 and the pot body 1 are detachably connected. In this way, the user can expose the storage space by separating the pot lid 2 and the pot body 1. In some other embodiments, the pot lid 2 and the pot body 1 can be connected by a hinge. In this way, the user can 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, and steam through holes 22 are provided in the overflow prevention plate 21. During cooking, the steam in the storage space can reach the pot lid 2 through the steam through holes 22 and can be further discharged from the pot lid 2. Thereby, the pressure intensity in the storage space is reduced, and the overflow of the juice is prevented. A seal ring pressing ring 4 and a seal ring 5 can also be provided at the connection part between the overflow prevention plate 21 and the pot lid 2. The seal ring 5 seals the edge of the overflow prevention plate 21 and the pot lid 2, and the seal ring pressing ring 4 is used to press the seal ring 5 against the overflow prevention plate 21. In some embodiments, the overflow prevention plate 21 is detachable from the pot lid 2, which is convenient for cleaning the area between the overflow prevention plate 21 and the pot lid 2 and also convenient for maintaining the components in this area.

[0043] As shown in FIGS. 1-2, FIG. 4, and FIG. 6, the temperature measuring device 3 is provided on the pot lid 2, and at least a part of the temperature measuring device 3 is provided in the region between the overflow prevention plate 21 and the pot lid 2. By doing so, when the pot lid 2 is opened, the temperature measuring device 3 is at least partially hidden on the back side of the overflow prevention plate 21 (i.e., the side of the overflow prevention plate 21 facing the pot lid 2). Therefore, the entire pot lid 2 is relatively beautiful, and the juice in the pot body 1 is also less likely to splash onto the temperature measuring device 3. If the entire temperature measuring device 3 is provided in the region between the overflow prevention plate 21 and the pot lid 2, the entire temperature measuring device 3 is hidden on the back side of the overflow prevention plate 21.

[0044] As shown in FIGS. 3 and 5, the temperature measuring device 3 may include a temperature measuring unit 31, and the temperature measuring unit 31 is installed to detect the steam temperature in the pot body 1 and the temperature of the overflow prevention plate 21.

[0045] It should be noted that the "and" in "the temperature measuring unit 31 is installed to detect the steam temperature in the pot body 1 and the temperature of the overflow prevention plate 21" does not necessarily mean to indicate simultaneity. It indicates that the temperature measuring unit 31 has the ability to detect the steam temperature in the pot body 1 and the ability to detect the temperature of the overflow prevention plate 21. It may detect the steam temperature in the pot body 1 in one time period and detect the temperature of the overflow prevention plate 21 in another time period, or it can also detect the steam temperature in the pot body 1 and the temperature of the overflow prevention plate 21 simultaneously, and is not limited thereto.

[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. When the first heating device operates, the temperature of the pot body 1 can be raised, so as to heat the food ingredients in the storage space. When the second heating device operates, similarly, the temperature of the pot body 1 can be indirectly raised, so as to heat the food ingredients in the storage space.

[0047] In some embodiments, when the cooking appliance 10 turns on the cooking function, first, the first heating device turns on the heating, and the temperature measurement unit 31 acquires the steam temperature in the pot body 1. When the steam temperature in the pot body 1 reaches the first preset temperature, further, the second heating device is controlled to turn on the heating. The temperature measurement unit 31 acquires 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 juice in the pot body 1.

[0048] The cooking appliance 10 according to the embodiment of the present invention is provided with a temperature measurement device 3 including a temperature measurement unit 31, and the temperature measurement unit 31 is installed so as to detect the steam temperature in the pot body 1 and the temperature of the overflow prevention plate 21. Accordingly, the heating device of the pot lid 2 can be controlled according to the temperature of the overflow prevention plate 21, which is helpful for improving the accuracy of the control.

[0049] In some embodiments of the present invention, as shown in FIGS. 2-5, the temperature measurement device 3 is housed in the pot lid 2 so as not to extend from the overflow prevention plate 21. In this way, the entire temperature measurement device 3 is hidden behind the overflow prevention plate 21. When the pot lid 2 is opened, the entire pot lid 2 is beautiful, and it is also possible to prevent the juice in the pot body 1 from splashing onto the temperature measurement device 3.

[0050] In some embodiments of the present invention, as shown in FIGS. 3 and 5, the temperature measuring device 3 may further include a heat conduction cover 33. The temperature measuring unit 31 is located within the heat conduction cover 33. The heat conduction cover 33 can physically protect the temperature measuring device 3, and the temperature measuring unit 31 contacts the heat conduction cover 33 to sense the temperature. The heat conduction cover 33 is disposed in close contact with the surface of the overflow prevention plate 21 opposite to the pot body 1. By doing so, the heat conduction cover 33 does not extend into the pot body 1, and the heat conduction cover 33 can transmit the temperature of the overflow prevention plate 21 to the temperature measuring unit 31. Therefore, the temperature measuring unit 31 indirectly detects the temperature of the overflow prevention plate 21. The overflow prevention plate 21 is provided with steam through holes 22, and the steam through holes 22 correspond to a part of the heat conduction cover 33. By doing so, the steam in the pot body 1 can directly reach the heat conduction cover 33 through the steam through holes 22. Thereby, the heat of the steam is transmitted 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 FIG. 3, the heat conduction cover 33 has a bottom wall, and the bottom wall has a first bottom wall portion 331. The first bottom wall portion 331 is used for fitting with the temperature measuring unit 31. The temperature measuring unit 31 can contact the first bottom wall portion 331 and sense the temperature of the first bottom wall portion 331. The steam through holes 22 face the first bottom wall portion 331. By doing so, the steam directly reaches the first bottom wall portion 331 through the steam through holes 22. Therefore, the temperature measuring unit 31 that fits with the first bottom wall portion 331 can accurately detect the steam temperature in the cookware.

[0052] Since the area of the steam through holes 22 is smaller than the bottom wall area of the heat conduction cover 33, it is possible to prevent the heat conduction cover 33 from falling into the pot body 1 from the steam through holes 22.

[0053] In some embodiments of the present invention, as shown in FIGS. 3 and 5, the temperature measuring device 3 may further include a mounting portion 34 and a positioning portion 35. The heat conduction 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. The mounting through hole 341 can position the temperature measuring portion 31 and ensure that the position of the temperature measuring portion 31 is accurate. The positioning portion 35 is mounted on the mounting portion 34. The positioning portion 35 is positioned and fitted to the pot lid 2 to limit the mounting direction of the temperature measuring device 3 and make the temperature measuring portion 31 correspond to the steam through hole 22. By doing so, after the steam reaches the heat conduction cover 33 through the steam through hole 22, heat is transferred to the temperature measuring portion 31 behind the heat conduction cover 33. Specifically, as shown in FIGS. 1 and 5, the positioning portion 35 has a limit baffle 351. The limit baffle 351 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 portion 31 faces the steam through hole 22, and the temperature of the steam can be quickly transferred by the temperature measuring portion 31, reducing the delay in temperature sensing and helping to improve the accuracy of the measurement of the temperature measuring portion 31 for the steam temperature in the pot body 1.

[0054] In some embodiments of the present invention, as shown in FIGS. 3-5, the temperature measuring device 3 may further include a compression spring 36. The compression spring 36 is provided between the mounting portion 34 and the pot lid 2 and is used to apply an elastic force towards the direction of the overflow prevention plate 21 to the mounting portion 34, so as to make the heat conduction cover 33 closely contact and touch the overflow prevention plate 21.

[0055] In some embodiments of the present invention, as shown in FIGS. 6-9, the temperature measuring portion 31 may include a steam temperature measuring portion 311 and an overflow prevention plate temperature measuring portion 312. The steam temperature measuring portion 311 is used to measure the steam temperature in the pot body 1, and the overflow prevention plate temperature measuring portion 312 is used to measure the temperature of the overflow prevention plate 21.

[0056] In some embodiments of the present invention, as shown in FIGS. 6-9, the steam temperature measurement unit 311 extends at least partially into the pot body 1 with respect to the overflow prevention plate 21. By doing so, the steam temperature measurement unit 311 is at least partially immersed in the steam atmosphere inside the pot body 1, and the steam inside the pot body 1 can directly contact the steam temperature measurement unit 311, which helps to improve the accuracy of detection of the steam temperature measurement unit 311 for steam. The overflow prevention plate temperature measurement unit 312 is housed inside the pot lid 2. By doing so, the overflow prevention plate temperature measurement unit 312 can directly sense the temperature of the overflow prevention plate 21, and at the same time, prevent the contact between the steam and the overflow prevention plate temperature measurement unit 312, thereby preventing the steam temperature from interfering with the temperature sensing result of the overflow prevention plate temperature measurement unit 312.

[0057] In some embodiments of the present invention, as shown in FIGS. 7-8, the temperature measuring device 3 may further include a heat conduction cover 33, and the heat conduction cover 33 can physically protect the temperature measuring device 3. The heat conduction cover 33 has a cover body 333 and a protruding portion 334. The protruding portion 334 protrudes from the bottom wall of the cover body 333 toward the pot body 1 side. The protruding portion 334 penetrates through the steam through hole 22 provided in the overflow prevention plate 21 and extends into the pot body 1. The steam temperature measurement unit 311 is at least partially provided inside the protruding portion 334. By doing so, the steam temperature measurement unit 311 extends at least partially into the pot body 1, the steam inside the pot body 1 can directly contact the protruding portion 334, and the steam temperature measurement unit 311 measures the temperature of the protruding portion 334, thereby realizing an indirect temperature measurement of the steam temperature measurement unit 311 for steam. Providing the protruding portion 334 helps to improve the accuracy of detection of the steam temperature measurement unit 311 for steam.

[0058] In some embodiments of the present invention, as shown in FIGS. 7-9, an annular bottom wall portion 331 is formed on the bottom wall of the cover body 333. The annular bottom wall portion 331 is provided so as to surround the protruding portion 334. The overflow prevention plate temperature measurement unit 312 is fitted to the annular bottom wall portion 331 to sense the temperature.

[0059] In some embodiments of the present invention, as shown in FIGS. 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 to the lower end of the mounting portion 34. A mounting through hole 341 is provided in the mounting portion 34, and both the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312 are 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 protruding portion 334. The mounting through hole 341 can position the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312, ensuring that the positions of the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32 are accurate. Specifically, the mounting through hole 341 may include a first mounting through hole 341 and a second mounting through hole 341. The steam temperature measuring portion 311 is mounted in the first mounting through hole 341, and the overflow prevention plate temperature measuring portion 312 is mounted in the second mounting through hole 341. By doing so, the mutual interference between the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312 can be reduced.

[0060] The temperature measuring device 3 may further include a positioning portion 35. The positioning portion 35 is attached to the mounting portion 34. The positioning portion 35 is positioned and fitted to the pot lid 2 to limit the mounting direction of the temperature measuring device 3 and make the protruding portion 334 correspond to the steam through hole 22. By doing so, after the steam reaches the protruding portion 334, heat can be transferred to the steam temperature measuring portion 311 behind the protruding portion 334. Specifically, as shown in FIGS. 1 and 9, the positioning portion 35 has a limit baffle 351. The limit baffle 351 is suitable for being positioned and fitted to a positioning structure (such as a locking groove) on the pot lid 2, realizing the accuracy of the relative position between the temperature measuring device 3 and the pot lid 2. The steam temperature measuring portion 311 faces the steam through hole 22, which is helpful for improving the measurement accuracy of the steam temperature measuring portion 311 for the steam temperature in the pot body 1.

[0061] In some embodiments of the present invention, as shown in FIGS. 7-9, the temperature measuring device 3 may further include a compression spring 36. The compression spring 36 is provided between the mounting portion 34 and the lid 2, and applies an elastic force toward the overflow prevention plate 21 to the mounting portion 34, and is used to make the annular bottom wall portion 331 of the heat conduction cover 33 closely contact the overflow prevention plate 21.

[0062] In some embodiments of the present invention, as shown in FIGS. 3, 5, 7-9, the temperature measuring device 3 may further include a temperature controller 32. The temperature controller 32 is fitted with the overflow prevention plate 21 and cuts off after the temperature of the overflow prevention plate 21 exceeds the threshold value, and the use safety of the cooking appliance 10 can be improved. In some embodiments of the present invention, as shown in FIGS. 2-5, 7-9, the temperature controller 32 is housed in the lid 2 so as not to extend from the overflow prevention plate 21. By doing so, the temperature controller 32 is hidden behind the overflow prevention plate 21. When the lid 2 is opened, the whole lid 2 is beautiful, and the juice in the pot body 1 can be prevented from splashing onto the temperature controller 32.

[0063] In some embodiments, the temperature controller 32 may be a fuse. After the temperature of the overflow prevention plate 21 exceeds the threshold value, the temperature controller 32 melts and the second heating device is cut off.

[0064] In some embodiments of the present invention, the temperature measuring device 3 includes a temperature measuring portion 31 and a temperature controller 32. The temperature controller 32 can directly contact the overflow prevention plate 21. The temperature controller 32 can quickly sense the temperature of the overflow prevention plate 21. When the temperature of the overflow prevention plate 21 reaches the threshold value, the temperature controller 32 plays a role in fusing protection.

[0065] In some embodiments of the present invention, as shown in FIGS. 3, 5, 7-9, the temperature measuring device 3 may further include a temperature controller 32. The temperature controller 32 is fitted with the overflow prevention plate 21 and cuts off after the temperature of the overflow prevention plate 21 exceeds a threshold value. The temperature controller 32 is located within the heat conduction cover 33 and contacts the heat conduction cover 33 to sense the temperature. In the specific examples as shown in FIGS. 3 and 5, the heat conduction cover 33 is disposed in close contact with the surface of the overflow prevention plate 21 opposite to the pot body 1. By doing so, the temperature controller 32 does not extend into the pot body 1, and since the heat conduction cover 33 can transmit the temperature of the overflow prevention plate 21 to the temperature controller 32, the temperature controller 32 can indirectly detect the temperature of the overflow prevention plate 21. In the specific examples as shown in FIGS. 7-9, the heat conduction cover 33 has a cover body 333 and a protrusion 334. An annular bottom wall portion 3331 is formed on the bottom wall of the cover body 333. The annular bottom wall portion 3331 is provided so as to surround the protrusion 334. The overflow prevention plate temperature measurement unit 312 and the temperature controller 32 are provided symmetrically in the radial direction with respect to the protrusion 334, and both the overflow prevention plate temperature measurement unit 312 and the temperature controller 32 are fitted into the annular bottom wall portion 3331 to sense the temperature. In this way, since the overflow prevention plate temperature measurement unit 312 is far from the temperature controller 32, mutual interference can be avoided.

[0066] The heat conduction cover 33 has a second bottom wall portion 332, and the second bottom wall portion 332 is used for fitting with the temperature controller 32. The temperature controller 32 can contact the second bottom wall portion 332 and sense the temperature of the second bottom wall portion 332. Since the steam through hole 22 is offset from the second bottom wall portion 332, the interference of the steam temperature on the temperature controller 32 fitted with the second bottom wall portion 332 is small.

[0067] In some embodiments of the present invention, as shown in FIG. 3, the heat conduction cover 33 has a bottom wall, and the bottom wall has a first bottom wall portion 331 and a second bottom wall portion 332. The first bottom wall portion 331 is used for fitting with the temperature measurement unit 31, and the second bottom wall portion 332 is used for fitting with the temperature controller 32. The temperature measurement unit 31 can contact the first bottom wall portion 331 to sense the temperature of the first bottom wall portion 331, and the temperature controller 32 can contact the second bottom wall portion 332 to sense the temperature of the second bottom wall portion 332. The steam through hole 22 faces the first bottom wall portion 331. In this way, the steam can directly reach the first bottom wall portion 331 through the steam through hole 22, so that the temperature measurement unit 31 fitted with the first bottom wall portion 331 can accurately detect the steam temperature in the cookware, and since the steam through hole 22 is offset from the second bottom wall portion 332, the interference of the steam temperature on the temperature controller 32 fitted with the second bottom wall portion 332 is small.

[0068] In some embodiments of the present invention, since the equivalent diameter of the first bottom wall portion 331 is smaller than the equivalent diameter of the second bottom wall portion 332, the area of the second bottom wall portion 332 can be ensured to be large, and the contact area between the temperature controller 32 and the second bottom wall portion 332 can also be set large. Since the temperature controller 32 is prone to fusing at high temperatures, it is helpful for improving the use safety of the cooking appliance 10. When the first bottom wall portion 331 and the second bottom wall portion 332 are circular, the equivalent diameter refers to the diameter, that is, 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 the 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. That is, the equivalent diameter refers to the maximum distance between any two points on the portion.

[0069] In some embodiments of the present invention, as shown in FIGS. 3 and 5, the temperature measuring device 3 may further include a mounting portion 34 and a positioning portion 35, and the heat conduction 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 and the temperature controller 32 are mounted in the mounting through hole 341. The mounting through hole 341 can position the temperature measuring portion 31 and the temperature controller 32, ensuring that the positions of the temperature measuring portion 31 and the temperature controller 32 are accurate. Specifically, the mounting through hole 341 may include a first mounting through hole 341 and a second mounting through hole 341. The temperature measuring portion 31 is mounted in the first mounting through hole 341, and the temperature controller 32 is mounted in the second mounting through hole 341. By doing so, the mutual interference between the temperature measuring portion 31 and the temperature controller 32 can be reduced.

[0070] In some embodiments of the present invention, as shown in FIGS. 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 to 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. The portion of the steam temperature measuring portion 311 extending from the corresponding mounting through hole 341 is inserted into the protruding portion 334. The mounting through hole 341 can position the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32, ensuring that the positions of the steam temperature measuring portion 311, the overflow prevention plate temperature measuring portion 312, and the temperature controller 32 are accurate. Specifically, the mounting through hole 341 may include a first mounting through hole 341, a second mounting through hole 341, and a third mounting through hole 341. The steam temperature measuring portion 311 is mounted in the first mounting through hole 341, the overflow prevention plate temperature measuring portion 312 is mounted in the second mounting through hole 341, and the temperature controller 32 is mounted in the third mounting through hole 341. By doing so, the mutual interference between the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312 can be reduced.

[0071] The cooking appliance according to an embodiment of the present invention includes 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. The pot lid is attached to the pot body, a storage space is formed inside the pot body, and the pot lid has an open state. At this time, the storage space is exposed, and the user can perform related operations such as putting ingredients into the storage space or scooping rice from the storage space to the outside within the storage space. The pot lid also has a closed state, and at this time, the storage space is closed. In some embodiments, the pot lid and the pot body are removably connected. In this way, the user can expose the storage space by separating the pot lid and the pot body. In some other embodiments, the pot lid and the pot body can be connected by a hinge. In this way, the user can expose the storage space by rotating the pot lid.

[0073] The pot lid has an overflow prevention plate, and steam through holes are provided in the overflow prevention plate. During cooking, the steam in the storage space can reach the pot lid through the steam through holes and may be further discharged from the pot lid to prevent the overflow of juice. A seal ring pressing ring and a seal ring can also be provided at the connection part between the overflow prevention plate and the pot lid. The seal ring seals the edge of the overflow prevention plate and the pot lid, and the seal ring pressing ring is used to press the seal ring against the overflow prevention plate. In some embodiments, the overflow prevention plate is removable from the pot lid, which is convenient for cleaning the area between the overflow prevention plate and the pot lid and for maintaining the components in this area.

[0074] The temperature measuring device is provided on the pot lid, and at least a part of the temperature measuring device is provided in the region between the overflow prevention plate and the pot lid. By doing so, when the pot 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 pot lid), so that the entire pot lid is relatively beautiful, and the juice in the pot body is also less likely to splash onto the temperature measuring device. When the entire temperature measuring device is provided in the region 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, and the temperature measuring unit is installed to detect the steam temperature in the pot body and the temperature of the overflow prevention plate. It should be noted that "and" does not necessarily mean indicating simultaneity, but means that the temperature measuring unit has the ability to detect the steam temperature in the pot body and the ability to detect the temperature of the overflow prevention plate. It goes without saying that the steam temperature in the pot body can be detected in one time zone, the temperature of the overflow prevention plate can be detected in another time zone, or the steam temperature in the pot body and the temperature of the overflow prevention plate can be detected simultaneously, and it is not limited to this.

[0075] The first heating device is provided corresponding to the pot body and can be provided in the region between the bottom of the pot body and the housing of the cooking appliance. The second heating device is provided corresponding to the pot lid and can be provided in the region between the pot lid and the overflow prevention plate. When the first heating device operates, the temperature of the pot body can be raised, so that the food ingredients in the storage space can be heated. When the second heating device operates, similarly, the temperature of the pot body can be raised, so that the food ingredients in the storage space can be heated.

[0076] FIG. 10 is a flowchart of the heating control method of the cooking appliance. The heating control method of the cooking appliance according to the embodiment of the second aspect of the present invention can include the following steps.

[0077] S1. When the cooking appliance turns on the cooking function, control the first heating device to turn on the heating, and obtain the steam temperature in the pot body by the temperature measuring unit.

[0078] In one embodiment of the present invention, the cooking appliance is provided with a controller. When the cooking appliance turns on the cooking function, the controller controls the first heating device to turn on the heating. After the temperature measuring unit acquires the steam temperature inside the pot body, it 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 Stage case, the temperature measuring unit can only acquire the steam temperature inside the pot body.

[0079] S2. When the steam temperature inside the pot body reaches the first preset temperature, the second heating device is controlled to turn on the heating. The temperature measuring unit acquires the temperature of the overflow prevention plate, and controls the second heating device according to the temperature of the overflow prevention plate. In this Stage case, the temperature measuring unit can only acquire the temperature of the overflow prevention plate.

[0080] That is, the cooking process is divided into two Stage parts. In the first Stage part, the first heating device turns on the heating, and the temperature measuring unit acquires the steam temperature inside the pot body. In the second Stage part, the second heating device turns on the heating, and the temperature measuring unit acquires 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 directly depends on the temperature of the overflow prevention plate rather than the steam temperature. By doing so, the control of the second heating device becomes more accurate. At the same time, the second heating device participates in the heating operation in specific cases, which helps to meet various cooking requirements of the cooking appliance.

[0081] In one embodiment of the present invention, the cooking appliance is provided with a controller. When the steam temperature inside the pot body reaches the first preset temperature, the controller controls the second heating device to turn on the heating. After the temperature measuring unit acquires the temperature of the overflow prevention plate, it transmits the overflow prevention plate temperature value to the controller. The controller further controls the heating power of the second heating device according to the temperature of the overflow prevention plate.

[0082] According to the heating control method of the cooking appliance according to an embodiment of the present invention, the steam temperature inside the main body of the pot is obtained by the temperature measurement unit. When the steam temperature inside the main body of the pot reaches a first preset temperature, the second heating device is controlled to turn on the heating. Further, the temperature of the overflow prevention plate is obtained by the temperature measurement unit, and by controlling the second heating device according to the temperature of the overflow prevention plate, the control of the second heating device becomes more accurate.

[0083] In some embodiments of the present invention, when the steam temperature inside the main body of the pot reaches a first preset temperature, the heating control method of the cooking appliance may include the steps of determining the cooking information of the cooking appliance, 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. 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 curve that matches the cooking information. For example, the operating time lengths, power, etc. of the first heating device and the second heating device are controlled.

[0085] In some embodiments of the present invention, the cooking information includes the type of cooking, and the type of cooking may be rice, porridge, soup, beef 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 S21, the target temperature of the pot lid is determined according to the type of cooking. Different types of cooking have different target temperatures of the pot lid. After the user selects the type of cooking, the controller adjusts the corresponding target temperature of the pot lid. In S22, the temperature difference between the temperature of the overflow prevention plate and the target temperature of the pot lid is specified, and the heating power of the second heating device is adjusted according to the temperature difference to adapt the temperature of the overflow prevention plate to the target temperature of the pot lid.

[0086] Specifically, if 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. If 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, avoiding the temperature of the overflow prevention plate exceeding the target temperature of the pot lid, and at the same time, the power consumption of the cooking appliance can also be reduced.

[0087] As shown in FIG. 11, the heating control method of the cooking appliance according to a specific embodiment of the present invention is as follows: after starting cooking, first, turn on the heating of the first heating device and turn off the heating of the second heating device, and the temperature measurement unit detects the steam temperature in the pot body. When the temperature measurement unit detects that the steam temperature has reached T11, it determines that boiling has occurred, determines the current amount of rice and water by software, matches the preset cooking curve, and at the same time, turns on the heating of the first heating device and the second heating device, and the temperature measurement unit starts to detect the temperature of the overflow prevention plate. At the same time, the cooking type is determined by the program. When the cooking type is the function of the rice cooking type, it is controlled to keep the temperature of the overflow prevention plate at T12. When the cooking type is the function of the porridge or soup type, it is controlled to keep the temperature of the overflow prevention plate at T13. When the cooking type is other functions, it is controlled to keep the temperature of the overflow prevention plate at T14 until the cooking process ends.

[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. 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 the heating, the steam temperature measurement unit obtains the steam temperature in the pot body. After the second heating device turns on the 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 obtained steam temperature value. For example, when 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. When 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 turns on the heating, the heating control method of the cooking appliance further includes the step of adjusting the heating power of the first heating device according to the steam temperature in the inner pot body when the steam temperature in the inner pot body reaches a second preset temperature. Specifically, the second preset temperature is higher than the first preset temperature. After the steam temperature in the inner pot body reaches the second preset temperature, the heating power of the first heating device is decreased to reduce the power consumption of the cooking appliance.

[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, the third preset temperature is lower than the target temperature of the pot lid. When the temperature of the overflow prevention plate reaches the third preset temperature, the heating power of the second heating device can be appropriately decreased to save power consumption.

[0092] According to a specific embodiment of the present invention, the heating control method of a cooking appliance is as shown in FIG. 12. After starting cooking, first, turn on the heating of the first heating device and turn off the heating of the second heating device. The steam temperature measurement unit detects the steam temperature inside the pot body. When the steam temperature measurement 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 at the same time turns on the heating of the first heating device and the second heating device. The steam temperature measurement unit continues to monitor the steam temperature. When the temperature of the steam temperature measurement unit reaches T3, the software controls the heating power of the first heating device so that the rice and water boil sufficiently. Throughout the cooking process, the overflow prevention plate temperature measurement unit operates independently. When turning on the heating of the second heating device, first, it operates at the maximum power adjustment ratio preset by the software. When the temperature of the overflow prevention plate temperature measurement unit is greater than T2, the heating power adjustment ratio of the second heating device is decreased. When the temperature of the overflow prevention plate temperature measurement unit is greater than T, the program starts to control the overflow prevention plate temperature to be maintained at T4±T0 until the entire cooking process ends.

[0093] In the heating control method of the cooking appliance according to the embodiment of the present invention, the temperature is controlled step by step. When the first preset temperature is the boiling temperature, the steam temperature is detected before boiling by program control, and the boiling time is determined, so that overflow can be effectively prevented. By detecting the temperature of the overflow prevention plate after boiling, closed-loop control of the overflow prevention plate temperature is realized, and the second heating device can be accurately adjusted, thereby achieving a better cooking effect.

[0094] The cooking appliance according to the embodiment of the third aspect of the present invention includes a memory, a processor, and a heating control program of the cooking appliance stored in the memory and operable by the processor. When the processor executes the heating control program of the cooking appliance, the heating control method of the cooking appliance according to the embodiment of the second aspect is realized.

[0095] The cooking appliance according to an embodiment of the third aspect of the present invention executes, by a processor, a heating control program of the cooking appliance stored in a memory, acquires the steam temperature inside the main body of the pot by a temperature measuring unit, and when the steam temperature inside the main body of the pot reaches a first preset temperature, controls a second heating device to turn on the heating. Further, by acquiring the temperature of the overflow prevention plate by the temperature measuring unit and controlling the second heating device according to the temperature of the overflow prevention plate, the control of the second heating device becomes more accurate.

[0096] A computer-readable storage medium according to an embodiment of the fourth aspect of the present invention stores a heating control program of a cooking appliance. When the heating control program of the cooking appliance is executed by a processor, the heating control method of the cooking appliance according to the embodiment of the second aspect is realized.

[0097] When the stored heating control program of the cooking appliance according to the embodiment of the present invention is executed, the steam temperature inside the main body of the pot is acquired by a temperature measuring unit. When the steam temperature inside the main body of the pot reaches a first preset temperature, a second heating device is controlled to turn on the heating. Further, by acquiring the temperature of the overflow prevention plate by the temperature measuring unit and controlling the second heating device according to the temperature of the overflow prevention plate, the control of the second heating device becomes more accurate.
