[0002] With the development of technology, ovens have become an indispensable cooking tool in our lives. In related technologies, gas ovens are generally equipped with a burner, so the valve body needs to be frequently turned on and off during temperature control. This places high demands on the lifespan of the valve body, and the valve body is either fully open or fully closed, resulting in a large temperature gradient and significant fluctuations in the temperature control curve, which affects the cooking results.

[0042] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] The control method and apparatus, storage medium, and cooking equipment of the present invention are described below with reference to the accompanying drawings.

[0044] See Figure 1 and Figure 2 As shown, the cooking equipment includes a burner 11 and a fan 12 that supplies the burner 11 with the air required for combustion. The burner 11 includes a gas inlet and multiple burners. The fan 12 supplies the burner 11 with the air required for combustion. After heating the air, the burner 11 directs the heated gas through a through-hole 13 on the back of the cooking chamber into the cooking chamber to heat the food inside. A regulating valve assembly is provided between the gas inlet of the burner 11 and the multiple burners, allowing adjustment of the air intake of each burner.

[0045] Figure 3 This is a flowchart of a control method for a cooking device in one embodiment of the present invention.

[0046] like Figure 3 As shown, the present invention proposes a control method for a cooking device, which includes the following steps:

[0047] S10, obtain the target cooking temperature of the cooking equipment.

[0048] Specifically, different types of food require different cooking temperatures, and even the same type of food will have different cooking temperatures depending on its state. This embodiment uses sensors to acquire the type and state of the food, then determines the cooking temperature based on this information, and thus determines the target cooking temperature of the cooking equipment. For example, a lower temperature is needed when proofing dough in an oven, while a higher temperature is needed when baking. Of course, other methods can also be used to determine the target cooking temperature. For instance, the execution command from the cooking equipment can be obtained; different execution commands correspond to different target cooking temperatures. After obtaining the execution command, the corresponding target cooking temperature can be determined. Alternatively, the user can directly set the target cooking temperature of the cooking equipment, such as manually adjusting the temperature control module on the cooking equipment, or sending the target cooking temperature to the cooking equipment via a terminal device.

[0049] S20 controls the fan and regulating valve group according to the target cooking temperature to maintain the cooking temperature of the cooking equipment at the target cooking temperature.

[0050] Once the target cooking temperature is determined, the regulating valve group can be controlled according to the target cooking temperature so that the burner can heat the air to the corresponding target cooking temperature. For different working states of the burner, it is necessary to control the fan to execute different speeds to supply the burner with the corresponding amount of air, so as to ensure that the burner can perform combustion work normally and that the cooking temperature of the cooking equipment can be maintained at the target cooking temperature.

[0051] See Figure 4 The burner 11 includes a first burner 111 and a second burner 112. The regulating valve group includes a first steady-state valve 113 and a second steady-state valve 114. The first steady-state valve 113 is disposed between the gas inlet 115 and the first burner 111, and the second steady-state valve 114 is disposed between the gas inlet 115 and the second burner 112. The second steady-state valve 114 includes a first opening degree and a second opening degree, wherein the first opening degree is smaller than the second opening degree.

[0052] Specifically, in this embodiment, the burner 11 includes two burners, namely a first burner 111 and a second burner 112. The regulating valve assembly includes a first steady-state valve 113 and a second steady-state valve 114. The second steady-state valve 114 has multiple opening degrees, such as a closed state, a 50% opening degree, and a 100% opening degree. The first steady-state valve 113 has two opening degrees: a closed state and an open state. That is, when the first steady-state valve 113 is open, it is fully open; when it is closed, it is fully closed. The second steady-state valve 114 can have an intermediate opening degree, that is, in addition to being fully closed, the second steady-state valve 114 can also have a first opening degree and a second opening degree. The first opening degree can be 50%, and the second opening degree can be 100%.

[0053] It should be noted that in this embodiment, four firepower levels can be achieved by switching the first steady-state valve 113 and the second steady-state valve 114 on and off. The zero level is flameout, that is, both the first steady-state valve 113 and the second steady-state valve 114 are closed; the first level is low fire, that is, the first steady-state valve 113 is closed and the second steady-state valve 114 is open to the first degree; the second level is medium fire, that is, the first steady-state valve 113 is closed and the second steady-state valve 114 is open to the second degree; and the third level is high fire, that is, the first steady-state valve 113 is open and the second steady-state valve 114 is open to the second degree.

[0054] In some specific embodiments, such as Figure 5As shown, the regulating valve group also includes a first shut-off valve 116, a second shut-off valve 117, and a pressure regulating valve 118. The first shut-off valve 116 and the pressure regulating valve 118 are connected in series at the gas inlet 115. The second shut-off valve 117 is connected in series with the second steady-state valve 114 between the gas inlet 115 and the second burner 112.

[0055] Specifically, in order to prevent gas leakage and improve the safety of gas use, this embodiment may also provide a first shut-off valve 116, a second shut-off valve 117 and a pressure regulating valve 118 between the gas inlet 115 and the burner. The first shut-off valve 116 and the pressure regulating valve 118 are located directly close to the gas inlet 115. The first shut-off valve 116 forms the first barrier to prevent gas leakage, and the pressure regulating valve 118 can stabilize the gas pressure supplied to the burner. Since the second steady-state valve 114 has a first opening degree and a second opening degree, the second burner 112 is usually used to control the small flame and the large flame. Therefore, the second steady-state valve 114 is switched on and off frequently. In order to prevent gas leakage caused by damage to the second steady-state valve 114, and to reduce the frequency of use of the second steady-state valve 114, this embodiment also provides a second shut-off valve 117 between the gas inlet 115 and the second burner 112. When the second steady-state valve 114 needs to be closed, the same effect can be achieved by closing the second shut-off valve 117. Therefore, the number of times the second steady-state valve 114 is switched on and off is reduced, thereby improving the service life of the second steady-state valve 114. Alternatively, when the second steady-state valve 114 is damaged and cannot be closed, the second shut-off valve 117 can also be closed to prevent gas leakage. That is, the second shut-off valve 117 constitutes a second barrier to prevent gas leakage.

[0056] Additionally, it should be noted that the first burner 111 is also provided with a first nozzle for injecting gas into the first burner 111, and the second burner 112 is also provided with a second nozzle for injecting gas into the second burner 112. The first nozzle and the second nozzle are not shown in the figure. The first nozzle and the second nozzle can be integrated into the first burner 111 and the second burner 112 respectively, or they can be set independently. No specific limitation is made here.

[0057] In some embodiments, the burner further includes an igniter, which can be disposed on each individual burner bar to ignite the corresponding burner bar when it is necessary to ignite it. Figure 6 As shown, the control method of the cooking device in this embodiment further includes the following steps:

[0058] S601, obtain the burner start command.

[0059] S602 controls the fan to run at the first preset speed according to the start command.

[0060] S603 controls the igniter to perform ignition operation after the fan has been running at a first preset speed for a first preset time.

[0061] S604, after the ignition operation has been performed for a second preset time, controls the opening degree of the second steady-state valve to the first opening degree.

[0062] Specifically, the burner's start command can be generated by the cooking equipment, specifically by the temperature selection device and start button on the equipment. The user can select the appropriate cooking temperature through the temperature selection device and then press the start button to trigger the burner to start. To ensure the burner functions properly, after the start command is determined, the fan can be controlled to run at a first preset speed to supply the air required for combustion. After the fan has run at the first preset speed for a first preset duration, the igniter can be controlled to perform the ignition operation. The first preset duration can be two seconds, which can be determined based on the relative positions of the fan and burner. If the distance between the fan and burner is greater, the first preset duration can be longer; if the distance is shorter, the first preset duration can be shorter. For safe ignition, after the ignition operation has been performed for a second preset duration, the second steady-state valve can be controlled to open at a first opening degree, i.e., ignition at the lowest setting. This prevents excessive gas supply and potential accidents while ensuring successful ignition. In order to ensure successful ignition and improve the service life of the igniter, the second preset duration in this embodiment can be set to 0.5 seconds.

[0063] In some embodiments of the present invention, such as Figure 7 As shown, the fan and regulating valve assembly are controlled according to the target cooking temperature, including:

[0064] S701, when the target cooking temperature is within the first preset temperature range, obtain the first switching frequency of the second steady-state valve between the closed state and the first opening degree.

[0065] S702 controls the second steady-state valve according to the first switching frequency.

[0066] S703, when the second steady-state valve switches from the closed state to the first opening degree, the fan is controlled to run at the first preset speed.

[0067] S704, when the second steady-state valve switches from the first opening to the closed state, the control fan is shut down.

[0068] Specifically, after ignition, the fan and regulating valve assembly can be controlled according to the target cooking temperature to maintain the cooking temperature of the cooking equipment at the target cooking temperature. Specifically, the target cooking temperature can be determined first. If the target cooking temperature is determined to be within a first preset temperature range, then it can be determined to be in the low-temperature cooking stage. The first preset temperature range can be 40℃-100℃. To maintain the cooking chamber of the cooking equipment at the target cooking temperature, temperature control can be achieved by controlling the opening and closing of the second steady-state valve. Since the second steady-state valve is initially open during ignition, it can be switched between the first open state and the closed state during temperature control. Specifically, it can be switched at a first switching frequency, that is, the second steady-state valve is controlled to be in the first open state for a period of time, and then in the closed state for a period of time, i.e., switching between zero and one level. For example, it can be controlled to be in the first open state for 30 seconds with a one-minute cycle, and then in the closed state for 30 seconds. In the zero position, since the burner is in an off state, there is no need to turn on the fan, and the fan can be controlled to be turned off. In the first position, since the burner needs air for normal combustion, the fan is controlled to run at a first preset speed, which can optionally be 2000 revolutions per minute. It should be noted that the specific operation during the switch from the zero position to the first position can be referred to the ignition operation, and will not be repeated here.

[0069] In some embodiments of the present invention, such as Figure 8 As shown, the control method for the cooking equipment also includes the following steps:

[0070] S801, obtain the ignition status of the second burner.

[0071] S802, when it is determined that the second burner has been successfully ignited according to the ignition status, controls the opening of the second steady-state valve to the second opening, and after the second steady-state valve runs at the second opening for a third preset time, controls the fan to run at the second preset speed.

[0072] Specifically, after the ignition operation is completed, the ignition status of the second burner is acquired. This ignition status determines whether ignition was successful. If ignition fails, the ignition operation is re-executed. If ignition fails for a preset number of consecutive times, the igniter is deemed to be faulty and reported. This preset number of attempts can be three, five, etc. Once the ignition status confirms that the second burner has been successfully ignited, the opening of the second steady-state valve can be controlled to the second opening degree, i.e., first-level ignition and second-level operation, increasing the heating rate. After the second steady-state valve operates at the second opening degree for a third preset time, since the gas consumption is higher at this point, more air is needed for combustion assistance. Therefore, the fan can be controlled to operate at a second preset speed, which is higher than the first preset speed, and can be 3700 rpm. Optionally, the third preset time is four seconds.

[0073] In this embodiment, such as Figure 9 As shown, the fan and regulating valve assembly are controlled according to the target cooking temperature, including:

[0074] S801, when the target cooking temperature is within the second preset temperature range, controls the opening degree of the second steady-state valve to the first opening degree, and controls the fan to run at the first preset speed.

[0075] S902, obtain the second switching frequency of the second steady-state valve between the closed state and the first opening degree.

[0076] S903 controls the second steady-state valve according to the second switching frequency.

[0077] S904, when the second steady-state valve switches from the closed state to the first opening degree, the control fan runs at the first preset speed.

[0078] S905, when the second steady-state valve switches from the first opening to the closed state, the fan is controlled to shut down.

[0079] Specifically, if the target cooking temperature is within the second preset temperature range, the second steady-state valve will be in the second opening state after ignition. At this time, the fan and regulating valve assembly can be controlled according to the target cooking temperature to maintain the cooking temperature of the cooking equipment at the target cooking temperature. The second preset temperature range can be 101℃-160℃. To maintain the cooking chamber of the cooking equipment at the target cooking temperature, the temperature can be controlled by controlling the opening and closing of the second steady-state valve. Since the second steady-state valve is in the second opening state during ignition, during temperature control, the opening state of the second steady-state valve can be switched to the first opening state first, and the fan can be controlled to adapt to the first opening state, that is, the fan speed can be adjusted to the first preset speed. The second steady-state valve is then controlled to switch between the first open and closed states. Specifically, this switching can be based on a second switching frequency. That is, the second steady-state valve is controlled to be in the first open state for a period of time, followed by a period of time in the closed state, switching between the zero and first positions. For example, a one-minute cycle could be used, controlling the second steady-state valve to be in the first open state for 40 seconds, followed by a 20-second closed state. In the zero position, since the burner is in an extinguished state, there is no need to turn on the fan, and thus the fan can be controlled to be turned off. In the first position, since the burner requires air for normal combustion, the fan is controlled to run at a first preset speed, optionally 2000 rpm. It should be noted that the specific operation during the switch from the zero position to the first position is similar to the ignition operation and will not be elaborated further here.

[0080] In some embodiments of the present invention, such as Figure 10 As shown, the control method for the cooking equipment includes the following steps:

[0081] S1001, obtain the ignition status of the second burner.

[0082] S1002, when it is determined that the second burner has been successfully ignited according to the ignition status, the first steady-state valve is controlled to open and the second steady-state valve is controlled to open to a second opening degree. After the first steady-state valve is in the open state and the second steady-state valve is running at the second opening degree for a fourth preset time, the fan is controlled to run at a second preset speed.

[0083] Specifically, after the ignition operation is completed, the ignition status of the second burner is acquired. This ignition status determines whether ignition was successful. If ignition fails, the ignition operation is re-executed. If ignition fails for a preset number of consecutive times, the igniter is deemed to be faulty and reported. This preset number of attempts can be three, five, etc. Once the ignition status confirms that the second burner has been successfully ignited, the opening of the second steady-state valve is controlled to the second opening degree, and the first steady-state valve is also opened (i.e., ignition at the first setting, operation at the second setting), further increasing the heating rate. After a fourth preset time period with the second steady-state valve operating at the second opening degree and the first steady-state valve open, since the gas consumption is high at this point, more air is needed for combustion. Therefore, the fan is controlled to operate at a second preset speed, which is higher than the first preset speed, and can be 3700 revolutions per minute. Optionally, the fourth preset time period is four seconds.

[0084] In this embodiment, such as Figure 11 As shown, the fan and regulating valve assembly are controlled according to the target cooking temperature, including:

[0085] S1101, when the target cooking temperature is within the third preset temperature range, control the first steady-state valve to close.

[0086] S1102, obtain the third switching frequency of the second steady-state valve between the first opening degree and the second opening degree.

[0087] S1103 controls the second steady-state valve according to the third switching frequency.

[0088] S1104, when the second steady-state valve switches from the second opening to the first opening, the fan is controlled to run at the first preset speed.

[0089] S1105, when the second steady-state valve switches from the first opening to the second opening, the fan is controlled to run at the second preset speed.

[0090] Specifically, if the target cooking temperature is within the third preset temperature range, after ignition, the first steady-state valve is open, and the second steady-state valve is at its second opening degree. At this time, the fan and regulating valve assembly can be controlled according to the target cooking temperature to maintain the cooking temperature of the cooking equipment at the target cooking temperature. The third preset temperature range can be 161℃-210℃. To maintain the cooking chamber of the cooking equipment at the target cooking temperature, temperature control can be achieved by controlling the opening and closing of the second steady-state valve. Since the second steady-state valve is at its second opening degree and the first steady-state valve is open during ignition, the first steady-state valve can be closed first during temperature control. Then, the second steady-state valve can be switched between the second and first opening degrees. Specifically, this can be done at a third switching frequency, i.e., controlling the second steady-state valve to be at the second opening degree for a period of time, and then at the first opening degree for a period of time, i.e., switching between the first and second positions. For example, a cycle of one minute can be used, controlling the second steady-state valve to be at the second opening degree for 40 seconds, and then controlling it to be at the first opening degree for 20 seconds. In the second gear, since the burner requires more air for normal combustion, the fan is controlled to run at the second preset speed. In the first gear, since the burner requires air for normal combustion, the fan is controlled to run at the first preset speed. Optionally, the first preset speed can be 2000 rpm and the second preset speed can be 3700 rpm.

[0091] In another embodiment of the invention, such as Figure 12 As shown, the fan and regulating valve assembly are controlled according to the target cooking temperature, including:

[0092] S1201, when the target cooking temperature is within the fourth preset temperature range, the first steady-state valve is kept in the open state.

[0093] S1202, obtain the fourth switching frequency of the second steady-state valve between the first opening degree and the second opening degree.

[0094] S1203 controls the second steady-state valve according to the fourth switching frequency.

[0095] S1204, when the second steady-state valve switches from the second opening to the first opening, the fan is controlled to run at the third preset speed, and after the fan runs at the third preset speed for a fifth preset time, the fan is controlled to run at the second preset speed.

[0096] S1205, when the second steady-state valve switches from the first opening to the second opening, the fan is controlled to run at the second preset speed.

[0097] Specifically, if the target cooking temperature is within the fourth preset temperature range, after ignition is completed, the first steady-state valve is in the open state and the second steady-state valve is in the second opening state. At this time, the fan and regulating valve group can be controlled according to the target cooking temperature to maintain the cooking temperature of the cooking equipment at the target cooking temperature. The fourth preset temperature range can be 211℃-280℃. To maintain the cooking chamber of the cooking equipment at the target cooking temperature, temperature control can be achieved by controlling the duration of the second steady-state valve between the second and first opening degrees. Since the second steady-state valve is at the second opening degree and the first steady-state valve is open during ignition, the first steady-state valve can be kept open during temperature control. Then, the second steady-state valve can be switched between the second and first opening degrees. Specifically, the switching can be performed at a fourth switching frequency, that is, the second steady-state valve is controlled to be at the second opening degree for a period of time, and then at the first opening degree for a period of time, i.e., switching between the second and third levels. For example, the second steady-state valve can be controlled to be at the second opening degree for 40 seconds with a one-minute cycle, and then controlled to be at the first opening degree for 20 seconds. When switching from the second to the third gear, since the burner requires more air for normal combustion, but in order to avoid excessive gas flow to the burner during the switching process and to ensure that the fan does not disperse the gas, the fan can be controlled to run at the third preset speed for the fifth preset duration first, and then the fan can be controlled to run at the second preset speed. When switching from the third gear to the second gear, the fan can be controlled to still run at the second preset speed. Optionally, the fifth preset duration is four seconds, the third preset speed can be 2400 rpm, and the second preset speed can be 3700 rpm.

[0098] In some embodiments of the present invention, such as Figure 2 As shown, the burner 11 is located at the back of the cooking device to heat the gas entering the cooking chamber of the cooking device, and the fan 12 is located at the bottom of the burner 11 to provide the burner 11 with the air required for combustion.

[0099] Specifically, the fan 12 is located at the bottom of the burner 11, providing the necessary air for combustion upwards. Since the heat from the burner 11 rises, it does not flow over the fan 12 at the bottom, thus avoiding damage. This allows for the selection of a fan that is not heat-resistant, increasing the range of options and reducing the design cost of the cooking equipment. Furthermore, the cool air provided by the fan 12 can also cool the burner wall, preventing excessively high wall temperatures that could negatively impact the user experience.

[0100] In some embodiments of the present invention, such as Figure 13 As shown, the control method for the cooking equipment also includes the following steps:

[0101] S1301, Obtain the burner shutdown command.

[0102] S1302 controls the regulating valve group to close and the fan to run at the first preset speed according to the closing command, and controls the fan to stop running after the regulating valve group has been closed for a sixth preset time.

[0103] Specifically, in this embodiment, after the cooking device completes the cooking instruction, it can obtain a burner shutdown instruction. Based on the shutdown instruction, the burner can be controlled to shut down. After the burner shuts down, since there is still heat in the cooking chamber and the burner, the fan can be controlled to run continuously at a first preset speed for a sixth preset time to cool down the cooking chamber and the burner, thereby improving the service life of the cooking device. Specifically, the sixth preset time can be ten seconds, and the first preset speed can be 2000 revolutions per minute.

[0104] In summary, the control method for the cooking equipment in this embodiment of the invention can reduce the number of valve opening and closing cycles, improve the service life of the cooking equipment, and accurately control the cooking temperature of the cooking equipment, thereby improving the cooking effect.

[0105] Furthermore, the present invention also proposes a computer-readable storage medium storing a control program for a cooking device thereon, wherein when the control program for the cooking device is executed by a processor, the control method for the cooking device described in any of the above embodiments is implemented.
