Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a stove fire control device and a control method thereof. Background Art

[0002] At present, most traditional household gas stoves can only be manually controlled by a knob. Specifically, the knob is pressed to ignite, and then rotated counterclockwise to adjust the firepower.

[0003] With the development of society and the advancement of technology, people's quality of life requirements are getting higher and higher, and the demand for cooking different kinds of ingredients is also increasing. Most people look for their favorite recipes online for cooking. However, the recipes on the Internet only have recipes and cooking steps, and the descriptions of the firepower of gas stoves are mostly vague words such as high fire, low fire, and medium fire. The gas stoves in users' homes are different, and the corresponding high fire, low fire, and medium fire are bound to have different actual firepower, which will lead to a mismatch between the actual firepower and the required firepower, and users also need to adjust the firepower of the gas stove by manually rotating the knob, which will lead to untimely fire adjustment. However, Chinese cuisine pays the most attention to the control of fire. The superposition of these factors will inevitably lead to poor fire control, resulting in unsatisfactory cooking products.

[0004] To address this issue, stoves that use electric control valves such as motor valves and proportional valves to control the fire have been launched on the market, but these stoves are often expensive and need to be connected to 220V AC power.

[0071] Please refer to Figure 5Another aspect of the present invention provides a control method for the stove fire control device as described above, comprising the following steps:

[0072] S1: Start cooking, the user selects a preset recipe;

[0073] S2: The user turns knob 4 to ignite;

[0074] S3: Obtain the target firepower value W0 of the current step according to the preset recipe, and calculate the angle K0 that the knob 4 needs to rotate;

[0075] S4: Determine whether the current position K1 of the knob 4 is located at K0, if so, enter S5, if not, drive the structure 1 to move so that the current position K1 of the knob 4 is located at K0, and then enter S5;

[0076] S5: Cook according to the current fire value;

[0077] S6: Determine whether cooking is finished, if cooking is finished, go to S8, if cooking is not finished, go to S7;

[0078] S7: judging whether the target firepower value W0 needs to be adjusted according to the preset recipe, if so, returning to S3, if not, returning to S5;

[0079] S8: The driving structure 1 drives the knob 4 to rotate and reset to the off position.

[0080] Optionally, when the stove fire control device is used for the first time, the following calibration steps are also included:

[0081] S10: The user inputs the current power of the cooker through the input unit;

[0082] S20: The control unit clears the number of rotations C of the driving motor 11 of the driving structure 1;

[0083] S30: The user rotates the knob 4 to ignite, and rotates the knob 4 counterclockwise to the minimum fire position for a preset time t;

[0084] S40: Determine whether the knob 4 is rotated to the minimum fire position, if yes, proceed to 50, if no, return to S30;

[0085] S50: Calculate and save the total number of rotations C1 of the driving motor 11;

[0086] S60: Calculate and save the rotation angle corresponding to each fire power level according to the total number of rotations C1 of the driving motor 11 and the power of the stove;

[0087] S70: driving the motor 11 to rotate C1 revolutions clockwise;

[0088] S80: Determine whether the stove is turned off normally. If so, the calibration is successful. If not, return to S20 for recalibration.

[0089] Optionally, in S80, when the stove is not turned off normally, it returns to S20 for recalibration, and records the number of times n of returning to S20 for calibration. When n>m, the control unit instructs the speaker to issue a fault alarm.

[0090] Optionally, in this embodiment, m is 3.

[0091] Optionally, in S4, the driving structure 1 moves so that when the current position K1 of the knob 4 is at K0, the target rotation position of the driving motor 11 is reached;

[0092] Among them, C3 is the number of rotations of the driving motor 11 when the stove is at the minimum firepower, and C4 is the number of rotations of the driving motor 11 when the stove is at the maximum firepower; W1 is the minimum firepower value of the stove; W2 is the maximum firepower value of the stove. When the knob 4 of the stove in this embodiment rotates 90 degrees counterclockwise from the initial position, the firepower of the stove gradually increases to the maximum firepower value. When the knob 4 continues to rotate counterclockwise from the maximum firepower value to the bottom, the stove firepower component is reduced to the minimum firepower value. Therefore, C3=C1.

[0093] Optionally, in S40, determining whether the knob 4 is rotated to the minimum fire position includes the following steps:

[0094] It is determined whether the Hall element 15 has not detected the magnet signal for a continuous preset time t. If so, it is determined that the knob 4 has been rotated to the minimum fire position. If not, it is determined that the knob 4 has not been rotated to the minimum fire position.

[0095] Further, in S4, when the user presses the knob 4 and rotates the knob 4 counterclockwise from the initial position more than 90 degrees, the stove starts to ignite. Therefore, in S4, when K1<K0, it means that the firepower is too large at this time, and the control unit instructs the drive motor 11 to rotate, and then drives the knob 4 to rotate counterclockwise through the belt until K1=K0, and the drive motor 11 stops rotating, and the firepower adjustment is completed at this time; when K1>K0, it means that the firepower is too small at this time, and the control unit instructs the drive motor 11 to rotate, and then drives the knob 4 to rotate clockwise through the belt until K1-K0, and the drive motor 11 stops rotating, and the firepower adjustment is completed.

[0096] Optionally, S2 specifically includes the following steps:

[0097] The user presses the knob 4 and rotates it counterclockwise more than 90 degrees. At this time, the gas stove knob 4 drives the drive motor 11 to rotate through the belt, and the Hall element 15 continuously feeds back information to the control unit. If the Hall element 15 detects a counterclockwise rotation signal, the current position C0 of the drive motor 11 increases by 1. If the Hall element 15 detects a clockwise rotation signal, the current position C0 of the drive motor 11 decreases by 1. When the detected current position C0 of the drive motor 11 is greater than C4, it is recognized as the start of cooking and enters S3.

[0098] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
