All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
In accordance with an embodiment of the present invention, there is provided a gas leak detection method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that while a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a flowchart of a method for detecting a gas leak according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, acquiring parameters of the cooking utensil, wherein the parameters comprise at least one of the following parameters: a first temperature of the bottom of the cooking appliance, and an amount of water inside the cooking appliance;
the cooking appliance may be an electric pressure cooker or other appliance capable of cooking food under high pressure, but is not limited thereto. The first temperature may be a bottom temperature detected when the electric pressure cooker starts cooking. The water amount may be detected when the electric pressure cooker starts cooking.
In an optional scheme, the first temperature can be acquired in real time through a temperature sensor arranged at the bottom of an inner pot of the electric pressure cooker, and the water quantity in the pot can be acquired in real time through a water quantity acquisition sensor arranged in the electric pressure cooker.
Step S104, determining the target heating time of the cooking utensil based on the parameters;
if the electric pressure cooker leaks, a high-pressure environment cannot be formed in the electric pressure cooker, namely, the electric pressure cooker cannot be pressed upwards, so that whether the electric pressure cooker leaks air can be determined by detecting whether the electric pressure cooker can be pressed upwards or not. In order to avoid that the electric pressure cooker cannot be pressed upwards due to air leakage, the electric pressure cooker is always in a working state, and resource waste is caused, in the embodiment of the invention, the maximum time (namely the target heating time) required by the pressing of the electric pressure cooker can be predicted based on the bottom temperature and/or the water quantity of the electric pressure cooker, and the purpose of detecting whether the electric pressure cooker leaks air is realized by controlling the electric pressure cooker to heat in the time and detecting whether the electric pressure cooker presses upwards.
Because the basic temperature of the food is different, for example, the initial temperature detected after the fried food is put into the pan is higher than that detected after the common food is put into the pan, the temperature rise of the fried food is faster, and the corresponding heating time is shorter; while the temperature rise of common food is slower, and the corresponding heating time is longer. At this time, if the preset heating time is solidified to a preset value, for example, the target heating time is short, the fried food can be normally pressed up in the time period, and the ordinary food cannot be normally pressed up in the time period, which results in a fault of the erroneous determination detector. For another example, the target heating time is long, if the electric pressure cooker has an air leakage fault, potential safety hazards exist in the time period, and the taste of cooked food is influenced. Similarly, the amount of water introduced varies, and the influence on the heating time varies.
In an alternative, for the bottom temperature, the bottom temperature of the electric pressure cooker may increase according to a specific rule during the operation, that is, the temperature increase curve of the bottom temperature is a specific curve. On this basis, the above-described target heating time can be calculated based on the heating time for the bottom temperature rise to the second temperature.
In another alternative scheme, the more the water in the electric pressure cooker is, the longer the time for pressing is; the smaller the amount of water, the shorter the time required for the upward pressing. On the basis, the correlation between the water quantity and the time required for pressurizing can be determined in advance through experiments, so that the corresponding target heating time can be determined based on the obtained water quantity. Or a corresponding relation table of the water quantity and the time required by the upper pressure can be obtained in advance through experiments, so that the corresponding target heating time can be determined by looking up the table through the obtained water quantity.
Step S106, controlling the cooking appliance to work within the target heating time, and detecting whether the cooking appliance meets a preset condition when the target heating time is reached, wherein the preset condition is used for representing air leakage of the cooking appliance;
in the embodiment of the invention, whether the electric pressure cooker leaks air can be determined by detecting whether the electric pressure cooker can be pressed up when the target heating time is up, and particularly, whether the electric pressure cooker is pressed up can be detected in various ways. In an optional scheme, whether the electric pressure cooker is pressed upwards can be determined by detecting whether the pressure of the electric pressure cooker reaches a preset pressure. In another alternative scheme, whether the electric pressure cooker is pressed upwards can be determined by detecting whether a floater arranged in the electric pressure cooker floats upwards.
And step S108, determining whether the cooking utensil leaks air or not based on the detection result.
If the detection result is that the cooking appliance meets the preset condition, indicating that the cooking appliance leaks air; if the detection result shows that the cooking appliance does not meet the preset condition, the fact that the cooking appliance is airtight is indicated.
In an optional scheme, if the pressure of the electric pressure cooker is detected to be lower than the preset pressure, the electric pressure cooker cannot be pressed upwards, and air leakage of the electric pressure cooker is determined; if the pressure of the electric pressure cooker reaches the preset pressure, the electric pressure cooker can be pressed upwards, and the electric pressure cooker is determined to be airtight. In another optional scheme, if the fact that the floater does not float upwards is detected, the fact that the electric pressure cooker cannot press upwards is indicated, the fact that the electric pressure cooker leaks air is determined; if the float is detected to float upwards, the electric pressure cooker can be pressed upwards, and the electric pressure cooker is determined to be airtight.
Further, after determining that the electric pressure cooker is leaked, a corresponding cooking mode, for example, stopping cooking or performing an abnormal cooking mode, may be performed, so as to ensure the safety of the cooking appliance and ensure that the taste of the cooked food meets the user's requirements.
By adopting the embodiment of the invention, the target heating time of the cooking appliance is determined by acquiring the bottom temperature and/or the water quantity, whether the cooking appliance is leaked is determined by detecting whether the cooking appliance meets the preset condition when the target heating time is reached, and the purpose of detecting whether the cooking appliance is leaked is realized, so that a user can accurately know whether the cooking appliance is leaked, the technical effect of improving the detection accuracy is achieved, and the technical problem that the user cannot accurately know whether the cooking appliance is leaked in the related technology is solved.
Optionally, the parameters include: determining a target heating time of the cooking appliance based on the parameter at the first temperature, comprising: controlling the cooking appliance to work, and detecting a second temperature at the bottom of the cooking appliance; reading the working time of the cooking appliance under the condition that the second temperature reaches the preset temperature; a target heating time is determined based on the operating time.
Specifically, the second temperature may be a preset temperature, and in order to avoid a long heating time, the second temperature may be closer to the first temperature, for example, the difference between the two temperatures may be less than 10 ℃.
In an alternative scheme, when the electric pressure cooker starts to cook, the starting temperature T1 is obtained, the Time Time1 of heating to the temperature T2 is recorded, and the maximum Time Time2 required by the upper pressure can be calculated through the Time Time1 used by the temperature rise (T2-T1). Assuming that the temperature rise curve of the bottom temperature is a straight line, the slope of the straight line can be determined based on the temperatures T1 and T2 and the Time1, and further based on the slope, the temperature T1 and the pressing temperature, the corresponding maximum Time2 can be obtained.
The Time1 can be recorded by a timer, specifically, the Time is started when the electric pressure cooker starts cooking, and is stopped when the bottom temperature reaches T2, and the Time is the Time 1. The target heating time is determined through the heating time heated to the second temperature (such as the temperature T2), so that the target heating time is dynamically determined according to different cooking conditions, and the flexibility of the detection method is improved.
Optionally, detecting whether the cooking appliance meets a preset condition includes: acquiring the pressure inside the cooking appliance; judging whether the pressure reaches a preset pressure or not; if the pressure does not reach the preset pressure, determining that the cooking utensil meets the preset condition; and if the pressure reaches the preset pressure, determining that the cooking appliance does not meet the preset condition.
Specifically, the preset pressure may be a pressure set by a user before the electric pressure cooker starts to cook, and if the user does not set the preset pressure, the preset pressure may be a default pressure.
In an optional scheme, whether the electric pressure cooker leaks air can be determined by detecting whether the electric pressure cooker normally presses within the time required by pressing, and if the electric pressure cooker cannot normally press, the electric pressure cooker leaks air; if the electric pressure cooker can normally press upwards, the electric pressure cooker is determined to be airtight. Whether the cooking utensil leaks gas is confirmed through detecting whether the cooking utensil pushes up, need not additionally to set up detection device, reduces and detects the cost.
Optionally, the parameters include: under the condition of the water yield, whether the detection cooking utensil satisfies preset conditions includes: detecting whether a preset signal is received or not, wherein the preset signal is used for representing that a floater arranged in the cooking appliance floats upwards; if the preset signal is not received, determining that the cooking appliance meets the preset condition; and if the preset signal is received, determining that the cooking appliance does not satisfy the preset condition.
In an optional scheme, whether the electric pressure cooker leaks air or not can be determined by detecting whether the floater floats upwards within the time required by the upward pressure, and if the electric pressure cooker cannot normally press upwards, the electric pressure cooker leaks air; if the electric pressure cooker can normally press upwards, the electric pressure cooker is determined to be airtight. Whether the floater that sets up through detecting cooking utensil is the come-up and confirms cooking utensil whether leaks gas, improves and detects the accuracy.
Optionally, the amount of water is obtained, including one of: receiving input water quantity gear information and determining the water quantity based on the water quantity gear information; the water quantity is obtained through the water quantity obtaining sensor.
Specifically, the water amount obtaining sensor may include one of: a load cell, an ultrasonic wave, a capacitive sensor, a level sensor, but is not limited thereto and may be other sensors.
In an alternative, the user may manually input the cooking water level, so that the electric pressure cooker may determine the water level based on the received water level information. In another alternative, the current amount of cooking water may be obtained by a water amount obtaining sensor (e.g., a weighing sensor, an ultrasonic sensor, a capacitive sensor, a level sensor, etc.). The water quantity is detected in multiple modes, so that the detection method can be suitable for different cooking appliances, and the detection flexibility and the application range are improved. In addition, acquire the sensor through multiple water yield and detect the water yield for the water yield acquires the sensor and can be applicable to different cooking utensil, promotes and detects flexibility and application scope.
Optionally, after determining that the cooking appliance is air-leaking based on the detection result, the method further comprises one of: controlling the cooking appliance to stop working; and controlling the cooking appliance to perform cooking operation according to the abnormal cooking mode.
Specifically, the abnormal cooking mode may be preset, and a cooking mode for completing cooking may be ensured in case of air leakage of the electric pressure cooker. In order to achieve the consistency with the taste of the food cooked in the high-pressure environment, the abnormal cooking mode may be a cooking mode in which the cooking time is lengthened and the power is increased appropriately, or a high-power intermittent heating mode is adopted.
In an alternative scheme, after the air leakage of the cooking appliance is determined, the electric pressure cooker can be controlled to stop heating immediately and send an alarm for ensuring safety. In another alternative, after determining that the cooking appliance is air-leaking, in order to meet the cooking requirement of the user and avoid food waste, the abnormal cooking mode corresponding to the current cooking function may be continuously executed. Cooking utensil is controlled through multiple mode, improves cooking utensil's security to satisfy user's culinary art demand, avoid food extravagant.
Optionally, after the cooking appliance stops working or cooking is finished, the method further comprises at least one of the following steps: outputting first prompt information, wherein the first prompt information is used for prompting air leakage of the cooking appliance; and sending the first prompt message to a server, wherein the server is used for sending the first prompt message and the processing scheme to a target terminal.
Specifically, the first prompt message may be a text message, a voice message, a buzzer sound, a light message, or the like, but is not limited thereto, where the text message may be a corresponding error code, or may be other text that prompts an air leak. In the embodiment of the present invention, the first prompt information is an error code as an example. The target terminal may be a terminal such as a smart phone, an IPAD, a tablet computer, a palm computer, and a notebook computer of the user, but is not limited thereto. The processing scheme may be a solution determined in advance for different air leakage faults, for example, a user may be prompted for a maintenance mode and the like.
In an optional scheme, after the air leakage of the electric pressure cooker is determined, if the electric pressure cooker is controlled to stop heating, the electric pressure cooker can be prompted through the prompting module, for example, a corresponding error code is displayed in a panel, relevant information is uploaded to the cloud server, and the cloud server sends prompting information and a processing scheme to a user. In another optional scheme, after the air leakage of the electric pressure cooker is determined, the electric pressure cooker still completes the cooking process, so that the electric pressure cooker can prompt through a prompt module after the cooking is finished, for example, a corresponding error code is displayed in a panel, meanwhile, relevant information is uploaded to a cloud server, and the cloud server forwards the relevant information to a mobile phone of a user for displaying.
After the cooking utensil leaks gas, the first prompt information is output and sent to the server, the user is prompted to leak gas of the cooking utensil in time, the first prompt information and the processing scheme are sent through the server, and the user can conveniently process gas leakage faults in time.
Optionally, after sending the prompt message to the server, the method further includes: detecting whether the air leakage fault of the cooking appliance is successfully treated or not after the cooking appliance is started; if the gas leakage fault is not successfully processed, outputting second prompt information, wherein the second prompt information is used for prompting that the gas leakage fault of the cooking appliance is not successfully processed; and after receiving confirmation information, controlling the cooking appliance to perform a cooking operation according to the abnormal cooking mode, wherein the confirmation information is used for confirming that the cooking appliance can perform the cooking operation.
Specifically, the confirmation message may be a message generated by a user directly operating a preset key on the electric pressure cooker, or a message sent to the electric pressure cooker by a mobile phone when the user operates the mobile phone, but is not limited thereto.
In an optional scheme, when the electric pressure cooker is started up again, if the air leakage fault is determined to be not processed, for example, if a user forgets to process the air leakage fault in time, the user can be prompted for one time and confirmed by the user, and if the user confirms that the electric pressure cooker can be used, the abnormal cooking mode is continuously executed for cooking operation; if the user does not confirm, the electric pressure cooker stops working and waits for the user to process the fault.
The air leakage fault detection method comprises the steps of detecting a processing result of the air leakage fault, outputting second prompt information, timely reminding a user of processing the air leakage fault, and avoiding the user from forgetting.
