Below, the cooking utensil 10 and the heating control method for the cooking utensil 10 according to an embodiment of the present invention will be described in detail with reference to Figures 1 to 12.

As shown in Figures 1-2, 4, and 6, a cooking utensil 10 according to an embodiment of the present invention comprises a pot body 1, a pot lid 2, and a temperature measuring device 3.

The cooking appliance 10 may be an electric rice cooker, a pressure cooker, etc.

As shown in FIG. 1, the pot lid 2 is attached to the pot body 1, forming a storage space within the pot body 1, the pot lid 2 can be in an open state, at which time the storage space is exposed, and the user can perform related operations within the storage space, such as putting ingredients into the storage space or serving rice from the storage space to the outside. The pot lid 2 can also be in a closed state, at which time the storage space is closed. In some embodiments, the pot lid 2 and the pot body 1 are removably connected, so that 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, so that the user can expose the storage space by rotating the pot lid 2.

1, the pot lid 2 has an overflow prevention plate 21, and the overflow prevention plate 21 is provided with a steam through hole 22. During cooking, the steam in the storage space can reach the pot lid 2 through the steam through hole 22 and can be further discharged from the pot lid 2, thereby reducing the pressure strength in the storage space and preventing the juice from overflowing. A sealing ring retaining ring 4 and a sealing ring 5 can also be provided at the connection between the overflow prevention plate 21 and the pot lid 2, and the sealing ring 5 is used to seal the edge of the overflow prevention plate 21 and the pot lid 2, and the sealing ring retaining 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 is convenient for cleaning the area between the overflow prevention plate 21 and the pot lid 2, and is also convenient for performing maintenance on the parts in the area.

As shown in Figures 1-2, 4 and 6, the temperature measuring device 3 is provided on the pot lid 2, and at least a portion of the temperature measuring device 3 is provided within 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 within 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.

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.

It is important to clarify 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 simultaneously, 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 may detect the steam temperature inside the pot body 1 during one time period and the temperature of the overflow prevention plate 21 during another time period, or it may detect the steam temperature inside the pot body 1 and the temperature of the overflow prevention plate 21 simultaneously, and is not limited to this.

In some embodiments, a first heating device can be provided in the pot body 1 and a second heating device can 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.

In some embodiments, when the cooking function of the cooking utensil 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.

The cooking utensil 10 according to the 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 inside 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.

In some embodiments of the present invention, as shown in Figures 2-5, the temperature measuring device 3 is stored inside 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 juices in the pot body 1 are prevented from splashing onto the temperature measuring device 3.

In some embodiments of the present invention, as shown in Figures 3 and 5, the temperature measuring device 3 may further include a heat conductive cover 33, the temperature measuring unit 31 is located in the heat conductive cover 33, the heat conductive cover 33 can physically protect the temperature measuring device 3, and the temperature measuring unit 31 senses the temperature by contacting the heat conductive cover 33. The heat conductive cover 33 is arranged in close contact with the surface of the overflow prevention plate 21 opposite the pot body 1. In this way, the heat conductive cover 33 does not extend into the pot body 1, and the heat conductive 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 transmitting the heat of the steam to the heat conduction cover 33, and the temperature measurement unit 31 indirectly detects the steam temperature in the pot body 1.

In some embodiments of the present invention, as shown in FIG. 3, the heat-conducting cover 33 has a bottom wall, the bottom wall has a first bottom wall portion 331, the first bottom wall portion 331 is used to fit with the temperature measuring portion 31, the temperature measuring portion 31 can contact the first bottom wall portion 331, and senses the temperature of the first bottom wall portion 331. The steam through hole 22 faces the first bottom wall portion 331. In this way, the steam reaches the first bottom wall portion 331 directly through the steam through hole 22, so that the temperature measuring portion 31 that fits with the first bottom wall portion 331 can accurately detect the steam temperature in the pot.

The area of the steam through hole 22 is smaller than the bottom wall area of the heat conduction cover 33, so the heat conduction cover 33 can be prevented from falling through the steam through hole 22 into the pot body 1.

In some embodiments of the present invention, as shown in FIG. 3 and FIG. 5, the temperature measuring device 3 may further include an attachment portion 34 and a positioning portion 35, and the heat conductive cover 33 is fitted to the lower end of the attachment portion 34. An attachment through hole 341 is provided in the attachment portion 34, and the temperature measuring portion 31 is attached to the attachment through hole 341, which 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 attached to the attachment portion 34, and the positioning portion 35 is positioned and fitted to the pot lid 2, restricting the attachment direction of the temperature measuring device 3 and making the temperature measuring portion 31 correspond to the steam through hole 22. In this way, the steam reaches the heat conductive cover 33 through the steam through hole 22, and then transfers heat to the temperature measuring portion 31 behind the heat conductive cover 33. Specifically, as shown in FIG. 1 and FIG. 5, the positioning part 35 has a limit baffle 351, which is suitable for positioning and fitting into a positioning structure (e.g., 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 temperature of the steam can be transmitted quickly by the temperature measuring part 31, which helps to reduce the delay in temperature sensing and improve the measurement accuracy of the temperature measuring part 31 for the steam temperature in the pot body 1.

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 disposed between the mounting portion 34 and the pot lid 2 and is used to apply a resilient force to the mounting portion 34 in the direction of the overflow prevention plate 21, so as to bring the heat conductive cover 33 into sufficient close contact with the overflow prevention plate 21.

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 inside 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.

In some embodiments of the present invention, as shown in Figures 6-9, the steam temperature measuring unit 311 extends at least partially into the pot body 1 relative to the overflow prevention plate 21. In this way, the steam temperature measuring unit 311 is at least partially immersed in the steam atmosphere in the pot body 1, and the steam in the pot body 1 can directly contact the steam temperature measuring unit 311, which helps to improve the accuracy of the detection of steam by the steam temperature measuring unit 311. The overflow prevention plate temperature measuring unit 312 is stored in the pot lid 2. In this way, the overflow prevention plate temperature measuring unit 312 directly senses the temperature of the overflow prevention plate 21, and at the same time, the contact between the steam and the overflow prevention plate temperature measuring unit 312 can be prevented, thereby preventing the steam temperature from interfering with the temperature sensing result of the overflow prevention plate temperature measuring unit 312.

In some embodiments of the present invention, as shown in Figs. 7-8, the temperature measuring device 3 may further include a heat conductive cover 33, which can physically protect the temperature measuring device 3. The heat conductive cover 33 has a cover body 333 and a protruding portion 334, which protrudes from the bottom wall of the cover body 333 toward the pan body 1, and which extends into the pan body 1 through the steam through hole 22 provided in the overflow prevention plate 21, and the steam temperature measuring portion 311 is at least partially provided in the protruding portion 334. In this way, the steam temperature measuring portion 311 extends at least partially into the pan body 1, and the steam in the pan body 1 can directly contact the protruding portion 334, and the steam temperature measuring portion 311 measures the temperature of the protruding portion 334, thereby realizing the indirect temperature measurement of the steam temperature measuring portion 311 for the steam. Providing the protruding portion 334 helps to improve the accuracy of detection of the steam temperature measuring portion 311 for the steam.

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, the annular bottom wall portion 331 is arranged to surround the protrusion 334, and the overflow prevention plate temperature measurement portion 312 is fitted into the annular bottom wall portion 331 to sense the temperature.

In some embodiments of the present invention, as shown in Figures 7-9, the temperature measuring device 3 may further include an attachment portion 34, and the cover body 333 of the heat conduction cover 33 is fitted into the lower end of the attachment portion 34. An attachment through hole 341 is provided in the attachment portion 34, and both the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312 are attached to the attachment through hole 341. The portion of the steam temperature measuring portion 311 extending from the corresponding attachment through hole 341 is inserted into the protrusion 334. The attachment through hole 341 can position the steam temperature measuring portion 311 and the overflow prevention plate temperature measuring portion 312, and ensure 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 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, and in this way, mutual interference between the steam temperature measuring unit 311 and the overflow prevention plate temperature measuring unit 312 can be reduced.

The temperature measuring device 3 may further include a positioning portion 35, which is attached to the mounting portion 34, and the positioning portion 35 is positioned and fitted to the pot lid 2, restricting the mounting direction of the temperature measuring device 3 and making the protrusion 334 correspond to 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 positioning and fitting to a positioning structure (e.g., 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, and the steam temperature measuring portion 311 faces the steam through hole 22, which helps to improve the measurement accuracy of the steam temperature measuring portion 311 for the steam temperature in the pot body 1.

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 disposed between the mounting portion 34 and the pot lid 2 and is used to apply a resilient force to the mounting portion 34 in the direction of the overflow prevention plate 21, so as to bring the annular bottom wall portion 331 of the heat conductive cover 33 into sufficiently tight contact with the overflow prevention plate 21.

In some embodiments of the present invention, as shown in Figures 3, 5, 7-9, the temperature measuring device 3 may further include a temperature controller 32, which is engaged with the overflow prevention plate 21 and can be disconnected after the temperature of the overflow prevention plate 21 exceeds a threshold value, thereby improving the safety of use of the cooking utensil 10. In some embodiments of the present invention, as shown in Figures 2-5, 7-9, the temperature controller 32 is stored in the pot lid 2 so as not to extend beyond the overflow prevention plate 21. In this way, the temperature controller 32 is hidden behind the overflow prevention plate 21, and when the pot lid 2 is opened, the entire pot lid 2 is beautiful and the juice in the pot body 1 is prevented from splashing onto the temperature controller 32.

In some embodiments, the temperature controller 32 may be a fuse, and after the temperature of the overflow prevention plate 21 exceeds a threshold, the temperature controller 32 melts and the second heating device is disconnected.

In some embodiments of the present invention, the temperature measuring device 3 includes a temperature measuring unit 31 and a temperature controller 32, and 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 a threshold value, the temperature controller 32 plays the role of meltdown protection.

In some embodiments of the present invention, as shown in Figures 3, 5, 7-9, the temperature measuring device 3 may further include a temperature controller 32, which is fitted with the overflow prevention plate 21 and disconnects after the temperature of the overflow prevention plate 21 exceeds a threshold value, and the temperature controller 32 is located within the heat conductive cover 33 and contacts the heat conductive cover 33 to sense the temperature. 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 prevention plate 21 opposite to 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 prevention plate 21 to the temperature controller 32, so that the temperature controller 32 can indirectly detect the temperature of the overflow prevention plate 21. 7-9, the thermal conduction cover 33 has a cover body 333 and a protrusion 334, a bottom wall of the cover body 333 is formed with an annular bottom wall portion 3331 , the bottom wall of the cover body 333 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 3331 to sense the temperature. 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.

The thermally conductive cover 33 has a second bottom wall portion 332, which is used to engage 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 hole 22 is offset from the second bottom wall portion 332, there is little interference of the steam temperature with the temperature controller 32 engaged with the second bottom wall portion 332.

In some embodiments of the present invention, as shown in FIG. 3, the thermally conductive cover 33 has a bottom wall, 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 to engage with the temperature measuring portion 31, the second bottom wall portion 332 is used to engage with the temperature controller 32, the temperature measuring portion 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, so that the temperature measuring unit 31 that fits into the first bottom wall portion 331 can accurately detect the steam temperature inside the pot, and because the steam through hole 22 is misaligned with the second bottom wall portion 332, there is little interference with the steam temperature for the temperature controller 32 that fits into the second bottom wall portion 332.

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, so that the area of the second bottom wall portion 332 can be secured to be large, and the contact area between the temperature controller 32 and the second bottom wall portion 332 can also be set to be large, and since the temperature controller 32 is easily melted at high temperatures, it is useful for improving the safety of use of the cooking utensil 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 on which 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.

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.

The cooking appliance may be an electric rice cooker, a pressure cooker, etc. A pot lid is attached to the pot body, forming a storage space within the pot body, and the pot lid can be in an open state, exposing the storage space, and a user can perform related operations within the storage space, such as putting ingredients into the storage space or serving rice from the storage space to the outside. The pot lid can also be in a closed state, closing the storage space. In some embodiments, the pot lid and the pot body are removably connected, so that the user can 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, so that the user can expose the storage space by rotating the pot lid.

The pot lid has an overflow prevention plate, and the overflow prevention plate is provided with a steam through hole, and during cooking, steam in the storage space can reach the pot lid through the steam through hole and can be further discharged from the pot lid, preventing overflow of juice. A sealing ring retainer ring and a sealing ring can also be provided at the connection between the overflow prevention plate and the pot lid, the sealing ring seals the edge of the overflow prevention plate and the pot lid, and the sealing ring retainer ring is used to press the sealing 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 performing maintenance on the parts in the area.

The temperature measuring device is provided on the pot lid, and at least a part of the temperature measuring device is provided in the area between the overflow prevention plate and the pot lid. In this way, 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 less likely to splash onto the temperature measuring device. When the entire temperature measuring device is provided in 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 has 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 is necessary to explain that "and" does not necessarily mean to indicate the same time, but indicates 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, and it may detect the steam temperature in the pot body in one time period and the temperature of the overflow prevention plate in another time period, and it is of course possible to detect the steam temperature in the pot body and the temperature of the overflow prevention plate at the same time, and is not limited to this.

The first heating device is provided to correspond 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 to correspond 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, the pot body can be heated, thereby heating the ingredients in the storage space, and when the second heating device is operated, the pot body can be heated, thereby heating the ingredients in the storage space.

Figure 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.

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 obtains the steam temperature inside the pot body.

In one embodiment of the present invention, the cooking appliance is equipped with a controller, 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 pan 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. At this stage , the temperature measuring unit can only obtain the steam temperature in the pan body.

S2, when the steam temperature in the pot body reaches the first preset temperature, control the second heating device to turn on the heating, obtain the temperature of the overflow prevention plate by the temperature measuring unit, and control the second heating device according to the temperature of the overflow prevention plate. At this stage , the temperature measuring unit can only obtain the temperature of the overflow prevention plate.

That is, 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 obtains the steam temperature in the pan body. In the second stage , the second heating device turns on the heating, and the temperature measuring unit obtains the temperature of the overflow prevention plate. The second heating device in the pan lid heats the pan 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 on the steam temperature, and in this way, the control of the second heating device is more accurate. At the same time, the second heating device participates in the heating operation in certain cases, which helps to meet various cooking demands of the cookware.

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.

A method of controlling heating of a cooking utensil according to an embodiment of the present invention obtains the steam temperature in the pan body by a temperature measuring unit, and controls the second heating device to turn on heating when the steam temperature in the pan body reaches a first preset temperature. In addition, 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.

In some embodiments of the present invention, when the steam temperature in the pan body reaches a first preset temperature, the heating control method for the cooker may include determining cooking information for the cooker, 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.

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 curve that matches the cooking information, for example, controlling the operating time length, power, etc. of each of the first heating device and the second heating device.

In some embodiments of the present invention, the cooking information includes cooking types, which may be rice, porridge, soup, ribs, chicken, beans, etc. The step of controlling the second heating device according to the temperature of the spill prevention plate includes steps S21 and S22.
In step S21, a target temperature of the pot lid is determined according to a cooking type. Different cooking types have different target temperatures of the pot lid, and after the user selects a cooking type, the controller adjusts the target temperature of the pot lid correspondingly.
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.

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 while simultaneously reducing the power consumption of the cooking utensil.

In a specific embodiment of the present invention, the heating control method of the cooker is as shown in FIG. 11. After cooking starts, the first heating device is turned on and the second heating device is turned off, and the temperature measuring unit detects the steam temperature in the pot body. When the temperature measuring unit detects that the steam temperature reaches T11, it determines that the water has boiled, and uses the software to determine the current amount of rice and water, and matches the preset cooking curve. At the same time, the first heating device and the second heating device are turned on, and the temperature measuring unit starts to detect the temperature of the overflow prevention plate. At the same time, the cooking type is determined by the program. If the cooking type is a rice cooking function, the temperature of the overflow prevention plate is controlled to be kept at T12. If the cooking type is a porridge or soup function, the temperature of the overflow prevention plate is controlled to be kept at T13. If the cooking type is another function, the temperature of the overflow prevention plate is controlled to be kept at T14 until the cooking process is completed.

In some embodiments of the present invention, the temperature measuring unit may include a steam temperature measuring unit and an overflow prevention plate temperature measuring unit, the steam temperature measuring unit is used to measure the steam temperature in the pan body, and the overflow prevention plate temperature measuring unit is used to measure the temperature of the overflow prevention plate. After the first heating device turns on the heating, the steam temperature measuring unit obtains the steam temperature in the pan body, and after the second heating device turns on the heating, the overflow prevention plate temperature measuring unit obtains the temperature of the overflow prevention plate.

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, and 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.

In some embodiments of the present invention, after the second heating device turns on the heating, the heating control method for the cooking utensil further includes a step of adjusting the heating power of the first heating device according to the steam temperature in the pan body when the steam temperature in the pan 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 pan 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.

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, so as to save power consumption.

In a specific embodiment of the present invention, the heating control method of the cooker is as shown in FIG. 12. After cooking starts, the first heating device is turned on and the second heating device is turned off, and the steam temperature measuring unit detects the steam temperature in the pan body. When the steam temperature measuring unit detects that the steam temperature reaches T1, the software determines the current amount of rice and water, matches the preset cooking curve, and simultaneously turns on the heating of the first heating device and the second heating device. 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. During the entire cooking process, the overflow prevention plate temperature measuring unit operates independently. When the heating of the second heating device is turned on, it first operates at the maximum power adjustment ratio preset by the software. When the temperature of the overflow prevention plate temperature measuring unit is greater than T2, it reduces the heating power adjustment ratio of the second heating device. When the temperature of the overflow prevention plate temperature measuring unit is greater than T, the program begins to control the overflow prevention plate temperature to be kept at T4±T0 until the entire cooking process is completed.

In the heating control method for the cooking utensil according to the embodiment of the present invention, the temperature is controlled stepwise, and when the first preset temperature is the boiling temperature, the steam temperature is detected before boiling through program control, the boiling time is determined, and overflow can be effectively prevented, and the temperature of the overflow prevention plate is detected after boiling, so that the closed-loop control of the overflow prevention plate temperature can be realized and the second heating device can be accurately adjusted, thereby achieving a better cooking effect.

A cooking appliance according to an embodiment of the third aspect of the present invention includes a memory, a processor, and a cooking appliance heating control program that is stored in the memory and can be run 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.

When the stored cooking utensil heating control program is executed, the computer-readable storage medium according to an embodiment of the present invention obtains the steam temperature in the pot body by the temperature measuring unit, and when the steam temperature in the pot body reaches a first preset temperature, controls the second heating device to turn on the heating, and further obtains 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.
