[0051] The embodiments of the present invention are described in detail below:

[0052] The temperature control method of the cooking appliance provided by the embodiment of the present invention is shown in Figure 1 The structural schematic diagram of the cooking utensil shown in the figure, wherein the cooking utensil 100 comprises a cooking chamber 110, a heat source assembly 200, a driving assembly 300 and a control chip 500; the heat source assembly 200 is located in the cooking chamber 110; the driving assembly 300 is installed on the outer wall of the cooking chamber 110, and extends into the cooking chamber 110 to be transmission-connected with the heat source assembly 200 to drive the heat source assembly 200 to move; the driving assembly 300 is connected to the control chip 500; in this embodiment, the cooking utensil 100 is a cooking appliance with a baking function, including but not limited to a steaming and baking machine. A carrier can also be detachably installed in the cooking chamber 110, and the carrier is used to place food so that the cooking utensil can cook food; the carrier is detachably connected to the cooking chamber 110, which is convenient for disassembly and assembly of the carrier, and then convenient for cleaning, etc.; the carrier includes but is not limited to a shelf or a baking tray, and is not limited to its material, and the carrier can also be set as a heatable container bag. The heat source assembly 200 is used to convert electrical energy into heat to cook food mounted on the carrier. The driving assembly 300 is located above the cooking utensil, and is connected to the heat source assembly 200 through the top wall of the cooking utensil 100 to drive the heat source assembly 200 to rise and fall in the vertical direction. The driving assembly 300 is signal-connected to the control chip 500, and the driving assembly 300 can transmit electrical signals to the control chip 500. The cooking utensil 100 is usually provided with a control panel 120 of a touch structure or a control component of a mechanical structure to control the on / off and operation mode of the cooking utensil 100, and the control chip 500 is usually provided in the control panel 120 or the control component of the cooking utensil 100.

[0053] The execution body of the cooking appliance temperature control method of this embodiment may be the above-mentioned control chip, see Figure 2 A flow chart of a method for controlling the temperature of a cooking appliance is shown, the method comprising the following steps:

[0054] Step S100: When a start instruction is received, the driving component is triggered to drive the heat source component to move downward to a set position.

[0055] The above-mentioned start instruction can be triggered by the user through the control panel or control component on the cooking appliance, or the cooking appliance can be triggered when the operating mode reaches certain conditions. When the control chip receives the start instruction, it determines that the drive component needs to be turned on, and starts the drive component to drive the heat source component to descend to the set position.

[0056] The specific method of the control chip triggering the driving component to drive the heat source component to move downward to the set position is to send an open signal to the driving component, and after the driving component receives the open signal, it applies an external force to the heat source component to drive the heat source component to descend.

[0057] Step S200: When a reset instruction is received, the driving component is triggered to drive the heat source component to reset.

[0058] The above reset instruction can be triggered by the user through the control panel or control component on the cooking appliance, or the cooking appliance can be triggered when the operating mode reaches certain conditions. When the control chip receives the reset instruction, it determines that the heat source component needs to be reset, and starts the drive component to drive the heat source component to reset.

[0059] The specific method of the control chip triggering the driving component to drive the heat source component to reset is to send a reset signal to the driving component, and after receiving the reset signal, the driving component applies an external force to the heat source component to drive the heat source component to rise.

[0060] The heat source component in the above method is located in the cooking cavity, the driving component is installed on the outer wall of the cooking cavity and extends into the cooking cavity to be transmission-connected with the heat source component, and the driving component is connected to the control chip of the cooking utensil, so that when a start command is received, the driving component can be triggered to drive the heat source component to move downward to a set position; according to the common sense that the closer to the heating element, the higher the temperature, the heat source component automatically approaches the food under the drive of the driving component during the cooking process, so that the food obtains a higher temperature, meets the cooking requirements of the food, and avoids the problem that the cooking utensil cannot reach the temperature required for cooking the food; when a reset command is received, the driving component is triggered to drive the heat source component to reset, which is convenient for taking the food after cooking is completed, and avoids abnormal cooking of the food due to excessive temperature.

[0061] As a possible implementation, a temperature sensor is installed in the cooking cavity, and the temperature sensor is connected to the control chip; based on this, triggering the drive component to drive the heat source component to move downward to the set position may include the following steps: (1) obtaining the actual temperature value in the cooking cavity detected by the temperature sensor, (2) judging whether the actual temperature value is greater than a first set temperature value and less than a second set temperature value, and the second set temperature value is greater than the first set temperature value; (3) if so, triggering the drive component to drive the heat source component to move downward to the set position. The above-mentioned temperature sensor is installed in the cooking cavity, and the temperature sensor is powered on after the cooking appliance is turned on, and monitors the actual temperature value in the cooking cavity in real time, and sends the detected actual temperature value to the above-mentioned control chip. The above-mentioned first set temperature value is generally set to the highest temperature that the cooking appliance can reach in the prior art, and the second set temperature value is set according to the user's cooking needs, and its value is greater than the first set temperature value. The specific position and installation method of the temperature sensor in the cooking cavity can be determined as needed, and this embodiment does not limit this.

[0062] By setting a temperature sensor in the cooking chamber, when the actual temperature value detected by the temperature sensor reaches the first set temperature value and is less than the second set temperature value, the control chip sends a start signal to the drive component to trigger the drive component to drive the heat source component to move down to the set position. If the actual temperature detected by the temperature sensor does not reach the first set temperature value, or is higher than the second set temperature value, the drive component will not start. By judging whether to trigger the drive component to drive the heat source component to move down according to the actual temperature value in the cooking chamber, the control chip can effectively obtain the appropriate opportunity to automatically move the heat source component down without manual operation by the user, which effectively improves the convenience of user use.

[0063] As a possible implementation, a vertical distance meter is installed on the top wall of the cooking chamber, and the vertical distance meter is connected to the control chip; based on this, triggering the driving component to drive the heat source component to move downward to the set position can also include the following steps: (1) obtaining the actual distance value between the heat source component and the top wall of the cooking utensil detected by the vertical distance meter; (2) judging whether the actual distance value is less than the set distance value; (3) if not, triggering the driving component to shut down. The vertical distance meter is powered on after the driving component is started, and monitors the actual distance value between the heat source component and the top wall of the cooking utensil in real time, and sends the detected actual distance value to the control chip. When the driving component drives the heat source component to descend, the control chip sends a signal to the vertical distance meter to test the actual distance value; the control chip judges the difference between the actual distance value and the set distance value. If the actual distance value is less than the set distance value, it means that the distance between the heat source component and the food meets the descending requirement, and the driving component is started to move the heat source component downward; if the actual distance value is equal to or greater than the set distance value, it means that the distance between the heat source component and the food is too close and cannot meet the descending requirement, and the driving component is shut down. The installation method of the vertical rangefinder can be determined as needed, and this embodiment does not limit this.

[0064] By setting a vertical distance meter in the cooking chamber, when the actual distance value detected by the vertical distance meter is equal to or greater than the set distance value, the control chip sends a shutdown signal to the drive component. If the actual distance value detected by the vertical distance meter does not reach the set distance value, the drive component operates normally. By judging whether to shut down the drive component based on the actual distance value between the heat source component and the top wall of the cooking chamber, the control chip can effectively control the position of the heat source component to avoid the problem of safety hazards caused by the heat source component being too close to the food.

[0065] As an embodiment, triggering the drive assembly to drive the heat source assembly to move downward to a set position may also include the following steps: (1) controlling the drive assembly to move the heat source assembly downward according to a first set feed amount; (2) when the heat source assembly reaches a preset intermediate position, controlling the drive assembly to move the heat source assembly downward according to a second set feed amount until the heat source assembly moves downward to a set position; the first set feed amount is greater than the second set feed amount. By adjusting the distance first and then adjusting the distance, the control chip can effectively control the position of the heat source assembly, avoiding the problem of a safety hazard caused by the heat source assembly being too close to the food.

[0066] As an implementation, triggering the driving component to drive the heat source component to reset includes the following steps:

[0067] (1) obtaining the actual temperature value in the cooking cavity detected by the temperature sensor; (2) determining whether the actual temperature value is greater than a second set temperature value; (3) if so, triggering the driving component to drive the heat source component to reset. By controlling the reset of the heat source component according to the actual temperature value in the cooking cavity detected by the temperature sensor, the control chip can effectively control the position of the heat source component, avoiding the problem of the heat source component being too close to the food, which may cause safety hazards.

[0068] As another embodiment, triggering the driving component to drive the heat source component to reset includes the following steps: starting the timing when the driving component drives the heat source component to move downward to a set distance, and when the timing reaches a preset time, triggering the driving component to drive the heat source component to reset. By controlling the reset of the heat source component according to the timing, the control chip can effectively control the position of the heat source component to avoid the problem of the heat source component being too close to the food, which may cause safety hazards.

[0069] An embodiment of the present invention also provides a cooking appliance temperature control device, the cooking appliance comprising a cooking cavity, a heat source component, a drive component and a control chip; the heat source component is located in the cooking cavity; the drive component is installed on the outer wall of the cooking cavity, and extends into the cooking cavity to be transmission-connected with the heat source component to drive the heat source component to move; the drive component is connected to the control chip; the control chip is used to execute the above-mentioned cooking appliance temperature control method.

[0070] See also Figure 3 A schematic diagram of a cooking appliance temperature control device is provided, the device comprising the following modules:

[0071] The first control module 610 is used to trigger the driving assembly 300 to drive the heat source assembly 200 to move downward to a set position when receiving a start instruction;

[0072] The second control module 620 is used to trigger the driving assembly 300 to drive the heat source assembly 200 to reset when receiving a reset instruction.

[0073] In the above device, the heat source component 200 is located in the cooking cavity 110, the driving component 300 is installed on the outer wall of the cooking cavity 110, and extends into the cooking cavity 110 to be transmission-connected with the heat source component 200, and the driving component 300 is connected to the control chip 500 of the cooking appliance, so that when a start command is received, the driving component 300 can be triggered to drive the heat source component 200 to move downward to a set position; according to the common sense that the closer to the heating element, the higher the temperature, the heat source component 200 automatically approaches the food during the cooking process under the drive of the driving component 300, so that the food obtains a higher temperature, meets the cooking requirements of the food, and avoids the problem that the cooking appliance cannot reach the temperature required for cooking the food; when a reset command is received, the driving component 300 is triggered to drive the heat source component 200 to reset, which is convenient for taking the food after cooking is completed, and avoids abnormal cooking of the food due to excessive temperature.

[0074] As a possible implementation, a temperature sensor is installed in the cooking cavity, and the first control module is used to: obtain the actual temperature value in the cooking cavity detected by the temperature sensor, determine whether the actual temperature value is greater than the first set temperature value and less than the second set temperature value, and the second set temperature value is greater than the first set temperature value; if so, trigger the drive component to drive the heat source component to move downward to the set position. The above-mentioned temperature sensor is installed in the cooking cavity, and the temperature sensor is powered on after the cooking appliance is turned on, monitors the actual temperature value in the cooking cavity in real time, and sends the detected actual temperature value to the above-mentioned control chip. The above-mentioned first set temperature value is generally set to the highest temperature that the cooking appliance can reach in the prior art, and the second set temperature value is set according to the user's cooking needs, and its value is greater than the first set temperature value. The specific position and installation method of the temperature sensor in the cooking cavity can be determined as needed, and this embodiment does not limit this. By arranging the temperature sensor in the cooking cavity, when the actual temperature value detected by the temperature sensor reaches the first set temperature value and is less than the second set temperature value, the control chip sends a start signal to the drive component to trigger the drive component to drive the heat source component to move downward to the set position. If the actual temperature detected by the temperature sensor does not reach the first set temperature value, or is higher than the second set temperature value, the driving component will not start. By judging whether to trigger the driving component to drive the heat source component to move downward according to the actual temperature value in the cooking chamber, the control chip can effectively obtain the appropriate time to automatically move the heat source component downward without manual operation by the user, which effectively improves the convenience of user use.

[0075] As a possible implementation, a vertical distance meter is installed on the top wall of the cooking chamber; the first control module is also used to: obtain the actual distance value between the heat source component and the top wall of the cooking utensil detected by the vertical distance meter; determine whether the actual distance value is less than the set distance value; if not, trigger the drive component to shut down. The vertical distance meter is powered on after the drive component is started, monitors the actual distance value between the heat source component and the top wall of the cooking utensil in real time, and sends the detected actual distance value to the control chip. When the drive component drives the heat source component to descend, the control chip sends a signal to the vertical distance meter to test the actual distance value; the control chip determines the difference between the actual distance value and the set distance value. If the actual distance value is less than the set distance value, it means that the distance between the heat source component and the food meets the descent requirement, and the drive component is started to move the heat source component downward; if the actual distance value is equal to or greater than the set distance value, it means that the distance between the heat source component and the food is too close and cannot meet the descent requirement, and the drive component is shut down. The installation method of the vertical distance meter can be determined as needed, and this embodiment does not limit this. By setting a vertical distance meter in the cooking chamber, when the actual distance value detected by the vertical distance meter is equal to or greater than the set distance value, the control chip sends a shutdown signal to the drive component. If the actual distance value detected by the vertical distance meter does not reach the set distance value, the drive component operates normally. By judging whether to shut down the drive component based on the actual distance value between the heat source component and the top wall of the cooking chamber, the control chip can effectively control the position of the heat source component to avoid the problem of safety hazards caused by the heat source component being too close to the food.

[0076] As an implementation mode, the first control module is also used to: control the driving component to move the heat source component downward according to the first set feed amount; when the heat source component reaches the preset middle position, control the driving component to install the second set feed amount to move the heat source component downward until the heat source component moves downward to the set position; the first set feed amount is greater than the second set feed amount. By adjusting the distance first and then the distance, the control chip can effectively control the position of the heat source component to avoid the problem of safety hazards caused by the heat source component being too close to the food.

[0077] As an implementation mode, the second control module is further used to: obtain the actual temperature value in the cooking cavity detected by the temperature sensor; determine whether the actual temperature value is greater than the second set temperature value; if so, trigger the driving component to drive the heat source component to reset. By controlling the reset of the heat source component according to the actual temperature value in the cooking cavity detected by the temperature sensor, the control chip can effectively control the position of the heat source component to avoid the problem of safety hazards caused by the heat source component being too close to the food.

[0078] As another embodiment, the second control module is further used to start timing when the driving component drives the heat source component to move downward to a set distance, and when the timing reaches a preset time, trigger the driving component to drive the heat source component to reset. By controlling the reset of the heat source component according to the timing, the control chip can effectively control the position of the heat source component to avoid the problem of safety hazards caused by the heat source component being too close to the food.

The heat source assembly 200 is located in the cooking chamber 110 to realize the heating function of the cooking utensil; the heat source assembly 200 is arranged opposite to the carrier to realize the heating function of the heat source assembly 200 on the food on the carrier. The driving assembly 300 is installed on the outer wall of the cooking chamber 110, and the cooking chamber 110 provides support and fixation for the driving assembly 300; the driving assembly 300 is connected to the heat source assembly 200 in a transmission manner to realize that the driving assembly 300 provides power to the heat source assembly 200, thereby realizing the adjustment of the distance between the heat source assembly 200 and the carrier. According to the common sense that the closer to the heating element, the higher the temperature, the heat source assembly 200 automatically approaches the food under the drive of the driving assembly 300 according to the required temperature during the cooking process, so that the food reaches a higher temperature. The cooking utensil can obtain the effect of high-temperature cooking without changing the number and power of the original heating tubes 220, thereby improving the safety of the cooking utensil.

[0081] As an implementation method, see Figure 6The driving assembly 300 includes a driving member 310 and a movable slide rail 320. The driving member 310 is installed on the top of the cooking chamber 110. One end of the movable slide rail 320 is drivingly connected to the driving member 310, and the other end of the movable slide rail 320 extends into the cooking chamber 110 and is connected to the heat source assembly 200. The movable slide rail 320 is in a strip shape, and the length direction is arranged along the height direction of the cooking chamber 110. The heat source assembly 200 is clamped with the movable slide rail 320, so that the heat source assembly 200 and the movable slide rail 320 are detachably connected, which is convenient for assembling the cooking utensil. The movable slide rail 320 is first installed in the cooking chamber 110, and then the heat source assembly 200 is installed on the movable slide rail 320.

[0082] As an embodiment, two movable rails 320 are provided, and both movable rails 320 are transmission-connected to the driving member 310 and are respectively connected to the two ends of the heat source assembly 200. The two movable rails 320 are arranged at intervals along the length direction of the cooking utensil. A sealing member is sandwiched between the movable rail 320 and the side wall of the cooking utensil to prevent the steam or heat in the cooking chamber 110 from being lost. Two movable rails 320 are provided, and the two movable rails 320 are respectively connected to the two ends of the heat source assembly 200, so as to realize the simultaneous driving of the two ends of the heat source assembly 200, and prevent the heat source assembly 200 from being skewed when moving, thereby causing the problem of unstable heat control.

[0083] As a possible implementation, the driving assembly 300 further includes a fixed rail 330, which is mounted on the inner wall of the cooking chamber 110 and is provided with a slide groove extending in the height direction of the cooking chamber 110; the movable slide rail 320 is slidably matched with the slide groove. The fixed rail 330 is slidably matched with the movable slide rail 320, and the fixed rail 330 guides the moving direction of the movable slide rail 320 to prevent the movable slide rail 320 from being deflected when moving, resulting in unstable movement.

[0084] As a possible implementation, see Figure 7 The drive assembly 300 also includes a transmission group 340, a transmission shaft 350 and two driving gears 360; the input end of the transmission group 340 is connected to the driving member 310, and the output end is installed on the transmission shaft 350; the two ends of the transmission shaft 350 are respectively connected to the two driving gears 360, and the two driving gears 360 are respectively meshed with the two movable slide rails 320. The function of the transmission group 340 and the transmission shaft 350 is to ensure that the moving directions of the two movable slide rails 320 are the same while using a single driving member 310, so as to prevent the heat source assembly 200 from tilting. The driving gear 360 meshes with the movable slide rail 320 to realize that the drive assembly 300 drives the movable slide rail 320 to rise or fall.

[0085] As a possible implementation manner, the driving gear 360 is installed at both ends of the transmission shaft 350 , and the side wall of the movable slide rail 320 is meshed with the driving gear 360 .

[0086] As another possible implementation, see Figure 7 The driving assembly 300 further includes two direction-changing gear sets 370, which are respectively mounted at both ends of the transmission shaft 350; the direction-changing gear sets 370 include a first bevel gear 371 and a second bevel gear 372 meshing with each other, the first bevel gear 371 is mounted on the transmission shaft 350, and the second bevel gear 372 is connected to the driving gear 360. The second bevel gear 372 and the driving gear 360 are both mounted on a fixed shaft 380, and the axis of the fixed shaft 380 is on the same horizontal plane as the axis of the transmission shaft 350 and is perpendicular; the movable slide rail 320 meshes with the driving gear 360 toward the side wall of the cooking chamber 110. The following description is made by taking the clockwise rotation of the driving member 310 as an example: the driving member 310 rotates clockwise, and the transmission shaft 350 rotates counterclockwise through the transmission group 340, and the transmission shaft 350 drives the first bevel gear 371 to rotate counterclockwise, and the first bevel gear 371 drives the second bevel gear 372 to rotate clockwise, and the second bevel gear 372 drives the driving gear 360 to rotate clockwise, and the driving gear 360 drives the movable slide rail 320 to move downward. The first bevel gear 371 and the second bevel gear 372 cooperate to change the rotation direction, and then the movable slide rail 320 is meshed with the driving gear 360 toward the inner wall of the cooking chamber 110, so as to facilitate the installation of the fixed rail 330.

[0087] As a possible implementation, see Figure 7 The transmission group 340 includes a first spur gear 341 and a second spur gear 342 that mesh with each other. The first spur gear 341 is connected to the driving member 310, and the second spur gear 342 is installed on the transmission shaft 350.

[0088] As another possible implementation, the transmission group 340 includes a driving wheel, a driven wheel and a synchronous belt, the driving wheel is connected to the driving member 310, the driven wheel is installed on the transmission shaft 350, and the driving wheel and the driven wheel are connected by a synchronous belt.

[0089] As a possible implementation, the cooking appliance further includes a distance meter, which is installed on the top wall of the cooking chamber 110 to measure the position of the heat source assembly 200; the distance meter is connected to the driving assembly 300 by signal. The distance meter is configured as a displacement sensor, which is used to detect the position of the heat source assembly 200, and then detect the vertical distance between the food and the heat source assembly 200. Furthermore, a temperature sensor is also installed in the cooking chamber 110, and the temperature sensor is connected to the driving member 310 by signal.

[0090] As a possible implementation, the heat source assembly 200 includes a heat source shelf 210 and a heating tube 220, which is mounted on the heat source shelf 210 and is in driving connection with the driving assembly 300. The heating tube 220 is connected to the power supply through a cable, which can be partially hidden in the movable slide rail 320 or partially hidden in the side wall of the box to achieve the heating function of the heating tube 220. The heat source shelf 210 is formed by bending a tubular structure, which reduces the weight of the heat source shelf 210 and reduces the power required by the driving member 310.

[0091] Taking the above cooking utensil structure as an example, the cooking utensil temperature control method includes the following steps:

[0092] Step 1: Set the working mode and corresponding parameters on the control panel 120 and start the work;

[0093] Step 2: The control chip starts different heating elements (multiple heating elements are installed in the cooking device, wherein the heating elements include the heat source assembly 200 mentioned above) to work alternately or synchronously according to the set parameters, so that the temperature of the center of the cooking cavity is heated to the target temperature;

[0094] Step 3: If the set target temperature (the second set temperature value as above) is higher than the normal temperature range (35-250°C), the temperature sensor starts the driving member 310 to rotate forward after detecting that the temperature at the center of the cavity rises to 250°C (the first set temperature value as above), driving the heat source assembly 200 to descend close to the food for heating, so that the temperature rises to the target temperature, and at this time, the control panel 120 sets the timer T0;

[0095] Step 4: When the temperature reaches the target temperature or the timing ends, the driving member 310 is started to reverse, driving the heat source assembly 200 to rise and move away from the food; (Steps 3 and 4 may be repeated multiple times, depending on the cooking method and characteristics of the food);

[0096] Step 5: The height to which the heat source assembly 200 descends is determined by measuring the distance between the food and the original position of the heat source using the vertical distance meter 400, as follows:

[0097] a: When it is detected that the driving member 310 is to be started to drive the heat source assembly 200 to move downward, the control chip sends a command test to the vertical rangefinder 400, and the test distance is L1;

[0098] b: Compare the distance L1 and L0 (L0: the rated maximum distance between the heat source assembly 200 and the vertical distance meter 400) detected in step a; if: L1-L0<0; it means that the distance between the heat source assembly 200 and the food meets the descending requirement, start the driving member 310, and move the heat source assembly 200 downward; if: L1-L0=0, it means that the distance between the heat source assembly 200 and the food is too close and cannot meet the descending requirement; stop the driving member 310 from rotating;

[0099] Step 6: When the cooking work is completed, the control chip 500 turns off the heating element and stops the load; the work ends.

[0100] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
