Description

Technical Field

[0001] The present invention relates to the field of steam generator abnormality identification, and in particular to a method and system, equipment and medium for identifying an abnormal state of a steam generator. Background Art

[0002] Currently, most cooking appliances with steaming functions use temperature sensors to detect dry-burning of the steam generator and determine whether the steam generator is short of water, thereby controlling water intake. When the temperature sensor fails, the system often misidentifies that the steam generator is permanently short of water, causing the internal system of the cooking appliance to continuously allow water into the steam generator, resulting in large amounts of water accumulation, making cleaning difficult for users. In more serious cases, the accumulated water can overflow from the cooking appliance, flooding the kitchen. This inaccuracy in the existing methods for identifying abnormalities can lead to continuous water inflow and accumulation. Summary of the Invention

[0037] Figure 4 This is a structural diagram of an electronic device according to embodiment 4 of the present invention. DETAILED DESCRIPTION

[0038] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0039] Example 1

[0040] This embodiment provides a method for identifying abnormal conditions of a steam generator, such as Figure 1 As shown, the method includes the following steps:

[0041] Step 1: Obtain the temperature inside the steam generator cavity.

[0042] Start the device that matches the steam generator and obtain the temperature inside the steam generator cavity according to the temperature sensor in the device.

[0043] The equipment that matches the steam generator can specifically be a cooking machine, an electric rice cooker, a steamer, etc.

[0044] Step 2: Determine whether the temperature in the steam generator cavity is higher than a first preset temperature; if so, proceed to step 3; if not, proceed to step 4;

[0045] Step 3: Add water to the steam generator;

[0046] Step 4: Do not add water to the steam generator.

[0047] The preset first temperature is set according to the dry-burning temperature that the selected steam generator can reach. If the temperature in the steam generator cavity is higher than the first preset temperature, it is judged that the steam generator is in a dry-burning state and lacks water. The temperature sensor will control the equipment matched with the steam generator to supply water into the steam generator.

[0048] Step 5. If the temperature in the steam generator cavity is higher than the first preset temperature for a period longer than the first preset period and the first total amount of water inflow into the steam generator is greater than the first preset amount of water, the steam generator is identified as being in an abnormal state. The first total amount of water inflow represents the total amount of water inflow into the steam generator during the period higher than the first preset temperature.

[0049] The first preset water volume can be the maximum water volume that can be used according to the water intake of the selected steam generator. The first preset time length is a time range in which the steam generator is pre-set to be higher than the first preset temperature. When the time when the temperature inside the steam generator is higher than the first preset temperature is greater than the first preset time length, and if the water intake of the steam generator is greater than the first preset water volume during the time when the temperature inside the steam generator is higher than the first preset temperature, it is identified and judged that the steam generator is in an abnormal state.

[0050] This embodiment identifies anomalies based on both temperature and water inflow, more comprehensively identifying steam generator anomalies and effectively improving the accuracy of anomaly identification. This prevents water accumulation caused by continuous water inflow into the system due to misidentification of anomalies, effectively avoiding the risk of water overflow within the chamber. In one implementation, if the total amount of water inflow into the steam generator exceeds a second preset water volume within a second preset time period, the steam generator is identified as being in an abnormal state.

[0051] The second preset time duration is a preset time period during which the water intake of the steam generator is reset to zero. The second preset water volume is a preset maximum water intake range for the steam generator within the second preset time duration. If the water intake of the steam generator exceeds the second preset water volume within the second preset time duration, the steam generator is identified as being in an abnormal state.

[0052] This embodiment identifies whether the steam generator is abnormal by judging the water intake within a fixed time period, thereby avoiding misjudgment due to temperature errors and improving recognition accuracy.

[0053] In one practicable manner, different water inlet interval durations are set according to different working stages of the equipment matched with the steam generator.

[0054] Determine the working stage of the equipment matching the steam generator and set different water inlet time intervals according to different working stages.

[0055] If the device is in a preheating state, the water inlet interval duration of the steam generator is set to a third preset duration.

[0056] The third preset time is set according to the actual water consumption rate of the equipment matching the steam generator. When the equipment matching the steam generator is in the preheating state, the water inlet interval of the steam generator is set to the third preset time.

[0057] If the device is in a countdown state, the water inlet interval duration of the steam generator is set to a fourth preset duration.

[0058] The fourth preset time is set according to the actual water consumption rate of the equipment matching the steam generator. When the equipment matching the steam generator is in the countdown state, the water inlet interval of the steam generator is set to the fourth preset time.

[0059] The third preset time length is shorter than the fourth preset time length.

[0060] Get the total amount of second water inflow in all working stages.

[0061] The second total amount of water inflow refers to the total amount of water inflow obtained in the preheating stage and the countdown stage. The water inflow is recorded in both the preheating stage and the countdown stage to obtain the total amount of water inflow in the two stages.

[0062] It is determined whether the second total amount of water inflow to the steam generator is greater than a third preset water amount; if so, the water inflow to the steam generator is stopped.

[0063] The third preset water volume may refer to the rated water volume of the steam generator. It is determined whether the total water intake obtained by the steam generator in the two stages is greater than the rated water volume of the steam generator. If so, water intake into the steam generator is stopped.

[0064] This embodiment uses the present invention to identify abnormalities in terms of temperature and water intake, and more comprehensively identifies abnormalities in the steam generator, effectively improving the accuracy of abnormality identification, thereby avoiding the problem of water accumulation caused by continuous water intake into the system due to errors in identifying abnormalities. At the same time, the present invention also restricts water intake. When the water volume exceeds the standard, the water intake of the steam generator is restricted, effectively avoiding the risk of water overflow in the cavity. To a certain extent, it can also enable the cooking machine to maintain normal operation even when the temperature sensor has an abnormality.

[0070] Optionally, the identification system further includes: a second identification module 24;

[0071] The second identification module 24 is configured to identify that the steam generator is in an abnormal state if the total amount of water inflow into the steam generator is greater than a second preset amount of water within a second preset time period.

[0074] The water volume determination module 27 determines whether the second total amount of water inflow to the steam generator is greater than a third preset water volume, and if so, stops supplying water to the steam generator.

[0075] Optionally, the first setting module 25 includes: a second setting unit 251 and a third setting unit 252;

[0076] The second setting unit 251 is used to set the water inlet interval of the steam generator to a third preset time if the device is in a preheating state;

[0077] The third setting unit 252 is used to set the water inlet interval of the steam generator to a fourth preset time if the device is in a countdown state.
