[0002] A steam oven is a household appliance that integrates the functions of an oven and a steamer into one box. It is popular among many consumers because it can provide multiple functions such as single steaming, steam-baking, and baking, as well as saving living space. At present, the control processing module of the steam oven generally processes the detection signal output by the control panel module on the steam oven to determine whether the user touches the "steam-baking" function key or the "steaming" function key on the control panel of the steam oven. If so, a control signal is output to the steam generator to start the steam generator, and the steam generator is controlled to operate according to the preset time until the end.

[0003] However, in the prior art, it is impossible to analyze the working state of the steam generator from the perspective of the working steam efficiency during the working process of the steam generator, which is not conducive to timely control of the steam generator, and at the same time increases the abnormal risk of the steam generator, and it is impossible to monitor the water level, which leads to an increased risk of dry burning of the steam generator, which is easy to damage the steam generator and bring safety hazards. In addition, it is impossible to understand the risk of the heating state of the steam generator, which is not conducive to reasonable and targeted control of the steam generator, and reduces the stability of heating control of the steam generator;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1 to Figure 2 As shown, the present invention is a steam generator state monitoring and control system applied to a steam oven, comprising a steam monitoring and control platform, a steam effect processing unit, a deviation tracking unit, a dry burning risk unit, a thermal control management unit and a control management unit, the steam monitoring and control platform is connected to the steam effect processing unit in a one-way communication, the steam effect processing unit is connected to the deviation tracking unit, the dry burning risk unit and the control management unit in a one-way communication, the deviation tracking unit and the dry burning risk unit are connected to the control management unit in a one-way communication, the dry burning risk unit is connected to the thermal control management unit in a one-way communication, and the thermal control management unit is connected to the control management unit in a one-way communication;

[0036] The steam monitoring and control platform is used to collect steam information of the steam generator in the steam oven, and send the steam information to the steam efficiency processing unit. The steam efficiency processing unit is used to perform steam efficiency risk assessment feedback evaluation and analysis on the received steam information, so as to analyze whether the working state of the steam generator is normal from the perspective of steam efficiency, so as to manage and adjust the target steam generator according to the information feedback, so as to ensure the control accuracy and working stability of the target steam generator. The specific steam efficiency risk assessment feedback evaluation and analysis process is as follows:

[0037] The operation time period of the steam generator of the steam oven is collected and set as the time threshold, the steam generator of the steam oven is set as the target steam generator, the time threshold is divided into i sub-time periods, i is a natural number greater than zero, and the steam information of the target steam generator in each sub-time period is obtained, the steam information includes the steam generation amount and the energy consumption value;

[0038] The set steam information of the target steam generator is obtained, and the set steam information includes a steam generation amount range and an energy consumption value range. The steam information is compared and analyzed with the set steam information. If the steam generation amount falls within the steam generation amount range and the energy consumption value falls within the energy consumption value range, a stable signal is generated. If the steam generation amount falls within the steam generation amount range and the energy consumption value falls within the energy consumption value range, a risk signal is generated.

[0039] The number of generated risk signals and the number of stable signals are obtained, and the number of generated risk signals and the number of stable signals are set as the steam efficiency risk index, and the steam efficiency risk index is compared and analyzed with the stored preset steam efficiency risk index threshold:

[0040] If the ratio between the evaporation risk index and the preset evaporation risk index threshold is less than 1, a normal signal is generated;

[0041] If the ratio between the steam efficiency risk index and the preset steam efficiency risk index threshold is greater than or equal to 1, an abnormal signal is generated, and the normal signal or the abnormal signal is sent to the control management unit. After receiving the normal signal or the abnormal signal, the control management unit immediately performs the preset early warning operation corresponding to the normal signal or the abnormal signal, so as to manage and adjust the target steam generator according to the information feedback, so as to ensure the control accuracy and stability of the target steam generator;

[0042] When an abnormal signal is generated, the deviation tracking unit is used to respond to the abnormal signal and collect the operating parameter information of the target steam generator, and at the same time perform state deviation interference tracking evaluation analysis on the operating parameter information to understand whether the abnormal working state of the target steam generator is caused by abnormal energy supply and steam density compensation, so as to manage and adjust the energy supply and steam density compensation of the target steam generator to reduce the influence of energy supply and steam density compensation on the working state of the target steam generator, thereby helping to improve the working stability of the target steam generator. The specific state deviation interference tracking evaluation analysis process is as follows:

[0043] The operating parameter information of the target steam generator in the sub-time period corresponding to the risk signal is obtained. The operating parameter information includes a working parameter index and a compensation parameter index. The working parameter index and the compensation parameter index are compared and analyzed with the preset working parameter index threshold and the preset compensation parameter index threshold that are stored in the internal data entry:

[0044] If the working parameter index is less than the preset working parameter index threshold, no signal is generated;

[0045] If the working parameter index is greater than or equal to the preset working parameter index threshold, an energy supply deviation signal is generated;

[0046] If the compensation parameter index is less than the preset compensation parameter index threshold, no signal is generated;

[0047] If the compensation parameter index is greater than or equal to a preset compensation parameter index threshold, a compensation deviation signal is generated, and the energy supply deviation signal and the compensation deviation signal are sent to the control management unit. After receiving the energy supply deviation signal and the compensation deviation signal, the control management unit immediately performs preset warning operations corresponding to the energy supply deviation signal and the compensation deviation signal, so as to manage and adjust the energy supply and steam density compensation of the target steam generator, so as to reduce the influence of the energy supply and steam density compensation on the working state of the target steam generator, thereby helping to improve the working stability of the target steam generator;

[0048] In the embodiment of the present invention, the working parameter index indicates the frequency at which the value corresponding to the working parameter of the target steam generator deviates from the set threshold value. The working parameters include operating voltage, operating power, etc. It should be noted that the larger the value of the working parameter index is, the greater the risk of abnormal working stability of the target steam generator is.

[0049] In the embodiment of the present invention, the compensation parameter index indicates the frequency at which the corresponding value of the steam density compensation information of the target steam generator deviates from the set value. The steam density compensation information includes pressure and temperature. It should be noted that the larger the value of the compensation parameter index is, the greater the risk of abnormal working stability of the target steam generator is, and the greater the risk of deviation of steam generation amount is.

[0050] In the embodiment of the present invention, when steam metering is performed, it is necessary to correct the density change to ensure the accuracy of the metering. The density compensation is usually achieved by measuring the temperature and pressure of the steam.

[0051] Embodiment 2:

[0052] When a normal signal is generated, the dry burning risk unit is used to respond to the normal signal and collect the water level information of the target steam generator, and at the same time, the evaporation water level control demand evaluation and analysis is performed on the water level information, so as to adjust the water level information in time to reduce the impact of the water level information on the steam generation of the steam generator, thereby helping to reduce the working risk of the steam generator and improve the continuous stability of the steam generator. The specific evaporation water level control demand evaluation and analysis process is as follows:

[0053] The water level information of the target steam generator within the time threshold is obtained, and the water level information includes the water level depth, the total water level volume, etc. The water level information is compared and analyzed with the preset water level information, and the corresponding value of the obtained water level information is less than the number corresponding to the preset water level information, and it is set as the water level management index, and the water level management index is compared and analyzed:

[0054] If the water level management index is equal to zero, a feedback instruction is generated;

[0055] If the water level management index is not equal to zero, an alarm signal is generated and sent to the control management unit. After receiving the alarm signal, the control management unit immediately performs the preset warning operation corresponding to the alarm signal, so as to timely manage the water replenishment inside the equipment to ensure the stability and continuity of the steam generation;

[0056] When the feedback instruction is generated, the water inlet rate characteristic curve of the target steam generator within the time threshold is obtained, the maximum water inlet rate and the minimum water inlet rate are obtained from the water inlet rate characteristic curve, and the actual water inlet rate interval is constructed based on the maximum water inlet rate and the minimum water inlet rate. The actual water inlet rate interval is compared and analyzed with the standard water inlet rate interval:

[0057] If the maximum value in the water inflow rate interval is less than or equal to the maximum value in the standard water inflow rate interval, and the minimum value in the water inflow rate interval is greater than or equal to the minimum value in the standard water inflow rate interval, no signal is generated;

[0058] If the maximum value in the water inlet rate interval is less than or equal to the maximum value in the standard water inlet rate interval, and the minimum value in the water inlet rate interval is greater than or equal to the minimum value in the standard water inlet rate interval, a water inlet deviation signal is generated, and the water inlet deviation signal is sent to the control management unit. After receiving the water inlet deviation signal, the control management unit immediately performs a preset warning operation corresponding to the water inlet deviation signal, so as to adjust the water inlet rate in time, so as to reduce the influence of the water inlet rate on the steam generation amount of the steam generator, thereby helping to reduce the working risk of the steam generator and improve the continuous stability of the steam generator operation;

[0059] When a feedback instruction is generated, the thermal control management unit is used to respond to the feedback instruction, collect the heating information of the target steam generator, and perform a heating risk management and control evaluation operation on the heating information to determine the heating state risk level of the current target steam generator, so as to perform reasonable and targeted management and control on the target steam generator. The specific heating risk management and control evaluation operation process is as follows:

[0060] The heating information of the target steam generator within the time threshold is obtained, and the heating information includes a heating obstacle value and a heating risk index. The number of heating obstacle values ​​and heating risk indexes that are greater than or equal to a preset heating obstacle value threshold and a preset heating risk index threshold is set as a thermal control management value, and the thermal control management value is judged:

[0061] If the thermal control management value = 0, it is determined to be a first-level thermal control risk;

[0062] If the thermal control management value = 1, it is determined to be a level 2 thermal control risk;

[0063] If the thermal control management value = 2, it is determined to be a level 3 thermal control risk, wherein the heating control risks corresponding to the level 1 thermal control risk, the level 2 thermal control risk and the level 3 thermal control risk increase in sequence, and the level 1 thermal control risk, the level 2 thermal control risk and the level 3 thermal control risk are set as thermal control risk levels RJ, RJ = 1, 2, 3, and the corresponding thermal control risk level RJ of the target steam generator within the current time threshold is sent to the control management unit. After receiving the thermal control risk level RJ, the control management unit immediately displays the preset warning text corresponding to the thermal control risk level RJ, so as to intuitively understand the heating state risk level of the target steam generator, so as to carry out reasonable and targeted control, so as to improve the safety and reliability of the heating control of the target steam generator;

[0064] In the embodiment of the present invention, the thermal control risk level RJ=1 indicates a first-level thermal control risk, the thermal control risk level RJ=2 indicates a second-level thermal control risk, and the thermal control risk level RJ=3 indicates a third-level thermal control risk;

[0065] In the embodiment of the present invention, the heating resistance value represents the product value obtained by multiplying the average value of the scale thickness on the inner wall of the water storage chamber by the total volume of the scale after data normalization. It should be noted that the larger the value of the heating resistance value is, the greater the risk of abnormal heat transfer efficiency of the target steam generator is;

[0066] In the embodiment of the present invention, the heating risk index represents the difference between the surface feature image of the steam generator tube bundle and the standard surface feature image. It should be noted that the larger the value of the heating risk index is, the greater the corrosion risk of the steam generator tube bundle is.

[0067] In summary, the present invention analyzes whether the working state of the steam generator is normal from the perspective of steam efficiency, that is, performs steam efficiency risk assessment feedback assessment analysis on the steam information, so as to manage and adjust the target steam generator according to the information feedback situation to ensure the control accuracy and working stability of the target steam generator, and performs evaporation water level control demand assessment analysis on the water level information by means of information feedback, so as to timely adjust the water level information to reduce the influence of the water level information on the steam generation amount of the steam generator, thereby helping to reduce the working risk of the steam generator and improve the continuous stability of the steam generator. At the same time, based on the normal water level, the heating risk control assessment operation is performed on the heating information to determine the heating state risk level of the current target steam generator, so as to reasonably and targetedly control the target steam generator, and the state deviation interference tracking assessment analysis is performed on the operating parameter information in an information progressive manner to understand whether the abnormal working state of the target steam generator is caused by abnormal energy supply and steam density compensation, so as to manage and adjust the energy supply and steam density compensation of the target steam generator to reduce the influence of energy supply and steam density compensation on the working state of the target steam generator, thereby helping to improve the working stability of the target steam generator.

[0068] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each group of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
