Detailed Description
The application is described in further detail below with reference to fig. 1-9.
The embodiment of the application discloses an air leakage alarm method of a gas oven.
Referring to fig. 1, the gas leakage alarm method of the gas oven includes:
s1, acquiring the current temperature of an oven;
s2, acquiring the time which is elapsed when the current temperature reaches a first temperature threshold value, and taking the time as heating time;
s3, judging whether the heating time is matched with a time threshold;
s4, if not, acquiring the air pressure value of the gas pipeline;
s5, judging whether the air pressure value is smaller than an air pressure threshold value or not;
s6, if yes, outputting an early warning prompt;
s7, if not, outputting a temperature regulation prompt.
Specifically, when the gas oven is used for baking food, the gas needs to be provided through the gas bottle, and meanwhile, the oven is communicated with the gas bottle through the gas pipeline. An electromagnetic valve is fixedly arranged between the gas bottle and the gas pipeline, and the circulation of gas in the gas pipeline can be controlled through the opening and closing of the electromagnetic valve. And can be through setting up a plurality of gas pipelines, every gas pipeline connects different solenoid valves, and the flow when every solenoid valve open state is different.
And in the heating process of the oven, acquiring the time which passes when the current temperature reaches the first temperature threshold value as the heating time. And then comparing the heating time with a time threshold value, and judging whether the heating time and the time threshold value are matched. That is, whether the temperature rise time is within the range of the time threshold, for example, the time threshold is 10-15 minutes, if the temperature rise time is within the range, the temperature rise time is proved to be matched with the time threshold, otherwise, the temperature rise time is not matched.
If the heating time is not matched with the time threshold, the condition that the gas pipeline is likely to leak is proved, and the gas pressure value of the gas pipeline is acquired at the moment. The air pressure value can be obtained through air pressure gauge measurement connected with the gas pipeline, and the air pressure gauge is close to the oven, so that the air pressure value of the pipeline can be obtained better.
Then, whether the air pressure value is smaller than an air pressure threshold value is judged, wherein the air pressure threshold value is a range value, and the range value comprises an upper threshold value limit and a lower threshold value limit. If the air pressure value is smaller than the air pressure threshold value, namely smaller than the threshold lower limit, the air leakage phenomenon of the gas pipeline is proved to occur at high probability, and an early warning prompt is output at the moment. Thereby remind the staff, make the staff in time seek the reason that the problem took place. If the air pressure value is within the range of the air pressure threshold value, the temperature of the oven is proved to be possibly problematic, and a temperature adjustment prompt is output at the moment, so that a worker can be reminded of timely adjusting the baking temperature of the oven.
Through the mode, the state of the oven can be accurately judged, the air leakage of the oven can be alarmed, and then the use safety of the oven is improved. Through the mode, whether the air leakage occurs is judged when the air pressure value of the pipeline changes, whether the oven leaks air can be judged according to the requirement, and judging efficiency can be improved.
Referring to fig. 2, further, the foods of the oven are various, and the temperatures of the baking are different, so in another embodiment, the step S1 further includes the following steps before the current temperature of the oven is obtained:
s11, acquiring a menu list;
s12, acquiring food options to be roasted based on the menu list;
s13, acquiring a first temperature threshold, a regulating temperature and a baking time based on food options.
Specifically, before the oven performs the baking operation, a menu list is obtained, then food options to be baked are obtained according to the menu list, a plurality of different food options are arranged in the menu list, and a user can select corresponding food options according to the food to be baked. Different foods can be cooked according to food options, wherein the food options include food cooking information including a first temperature threshold, a temperature adjustment, and a cooking time.
The oven can then cook the food according to the first temperature threshold and adjust a subsequent cooking temperature of the oven according to the adjustment temperature, and adjust a cooking time of the food according to the cooking time. The method can improve the application range of the food baked by the oven and is convenient to operate.
Referring to fig. 3, in another embodiment, step S1, i.e. after obtaining the current temperature of the oven, further includes the following steps:
s21, judging whether the current temperature is equal to a first temperature threshold value or not;
s22, if yes, acquiring an adjusting value of the temperature of the oven;
s23, acquiring an adjusting temperature based on a first temperature threshold value and an adjusting value;
s24, obtaining baking time;
s25, controlling the oven to bake based on the adjusting temperature and the baking time.
When the food is roasted, the current temperature of the oven is obtained through the temperature sensor, and then the current temperature is compared with the first temperature threshold value, so that whether the current temperature is equal to the first temperature threshold value or not is judged. Since the food is roasted at a certain roasting temperature, the roasting temperature is the first temperature threshold. In some food baking processes, a secondary baking is generally performed in order to improve the taste of the baking. Thus, when the current temperature is equal to the first temperature threshold, i.e., the temperature of the food item being grilled reaches the grilling temperature of the first grilling, the adjustment of the temperature of the oven is obtained. The adjustment value can be obtained according to the temperature of the food needing secondary baking.
And after the regulating value is obtained, obtaining a regulating temperature according to the first temperature threshold value and the regulating value, wherein the regulating temperature is the temperature of the secondary baking of the food. If the temperature of the secondary baking is lower, the adjusting temperature is the value obtained by subtracting the adjusting value from the first temperature threshold value, and correspondingly, if the temperature of the secondary baking is higher, the adjusting temperature is the value obtained by adding the adjusting value to the first temperature threshold value.
And then obtaining the baking time, namely obtaining the secondary baking time of the food, and finally controlling the oven to bake according to the regulating temperature and the baking time. The specific mode can be that different solenoid valves are controlled to be opened, so that different amounts of fuel gas circulate in the fuel gas pipeline, the heating temperature of the oven is controlled, the baking temperature of the oven is adjusted according to food, the steps of human participation can be reduced in the baking process, the time delay caused by manual operation is reduced, and the baking quality of the food is ensured as much as possible.
Referring to fig. 4, further, in order to further determine whether the gas pipeline leaks, in another embodiment, step S26, before outputting the temperature adjustment prompt, further includes:
s31, acquiring the gas concentration of a gas pipeline of the oven;
s32, judging whether the gas concentration is matched with a concentration threshold value;
s33, if not, outputting an early warning prompt.
S34, if yes, carrying out the next step.
And detecting the gas concentration of the gas pipeline by a gas detector connected with the gas pipeline, and judging whether the gas concentration is matched with a concentration threshold value or not. By detecting the concentration, the amount of gas discharged in the gas cylinder is fixed, and if the gas leaks, the concentration of gas in the gas pipe decreases.
When the gas concentration matches the concentration threshold, it is proved that the gas pipeline has a high probability of no leakage, and the next step, that is, step S26, is to output a temperature adjustment prompt. If the gas concentration does not match the concentration threshold, the leakage of the gas is proved to occur with a high probability, but is not detected by the gas pressure value. And at the moment, the early warning prompt is continuously output to remind the staff.
The gas pressure and gas concentration mutually matched mode is used for detecting, so that whether gas is leaked or not can be further detected, the detection accuracy is improved, and the safety of the oven in the use process is further improved.
Referring to fig. 5, other ways than the way of matching the gas pressure with the gas concentration are possible, so in another embodiment, step S26, that is, before outputting the temperature adjustment prompt, further includes the following steps:
s41, acquiring the current weight of a gas cylinder connected with a gas pipeline;
s42, acquiring the residual weight of the internal combustion gas cylinder in preset time;
s43, acquiring a consumption weight based on the current weight and the residual weight;
s44, acquiring a consumption speed based on the consumption weight and the preset time;
s45, judging whether the consumption speed is greater than a preset speed;
s46, if yes, outputting an early warning prompt;
s47, if not, carrying out the next step.
Leakage of gas may cause an increase in the consumption rate of gas, and thus can be confirmed by determining a change in the weight of the gas bottle. Specifically, the current weight of the gas cylinder is acquired, and the acquisition mode can be acquired in real time through a pressure sensor arranged below the gas cylinder. The remaining weight of the gas cylinder is then acquired during a predetermined time, wherein the predetermined time is a fixed value, and the magnitude of the value can be determined according to the actual situation.
And then obtaining the consumed weight according to the current weight and the residual weight, namely, obtaining a value obtained by subtracting the residual weight from the current weight, namely, obtaining the consumed weight, namely, the weight of the gas consumed by the gas bottle in the preset time. And then the consumption speed is obtained according to the consumption weight and the preset time, namely, the consumption speed is obtained by dividing the consumption weight by the preset time.
And then judging whether the consumption speed is greater than a preset speed, namely judging whether the consumption speed of the fuel gas is abnormal. If the consumption speed is greater than the preset speed, the abnormal consumption of the fuel gas is proved to occur in a large probability, and an early warning prompt is output at the moment to remind workers to check in time, so that the safety of the oven in the use process is improved. Otherwise, it proves that the gas pipeline has high probability of no leakage, and the next step is continued, namely, step S26 is to output a temperature adjustment prompt. Through the combination of weight change and air pressure value, judge whether to take place to leak gas, can increase the variety of detection, further improve the accuracy of detection.
Referring to fig. 6, further, the output of the early warning prompt further includes the following steps:
s51, acquiring a cutting instruction;
s52, controlling the electromagnetic valve connected with the gas pipeline to be closed based on the cut-off instruction.
After the early warning prompt is output, the occurrence of air leakage is proved to be high in probability, and the cutting-off instruction is acquired at the moment. Then the electromagnetic valve is controlled to be closed according to the cutting-off instruction, so that the gas in the gas pipeline can be cut off, the possibility of danger is reduced, and the safety of the oven in the use process can be further improved.
Referring to fig. 7, when the gas in the gas bottle leaks, the service time of the gas bottle is changed, so that the replacement time of the gas bottle is changed, and in order to replace the gas bottle in time, in another embodiment, outputting the early warning prompt further includes:
s61, acquiring the total weight of the gas cylinder when the gas cylinder is full of gas;
s62, acquiring the estimated consumption time based on the total weight and the preset speed;
s63, acquiring residual consumed time based on the residual weight and a preset speed;
s64, acquiring the used time of the gas cylinder as the use time;
s65, acquiring actual use time based on the use time and the residual consumption time;
s66, acquiring initial service time of the gas cylinder;
s67, acquiring the estimated use time based on the initial use time and the estimated consumption time;
s68, acquiring a time difference value based on the estimated use time and the actual use time;
and S69, outputting the time difference value to remind related personnel to replace the gas cylinder.
Specifically, the total weight of the gas cylinder when it is full of gas, that is, the weight of the gas cylinder when it is not yet in use, is first obtained, and then the estimated time consumption, that is, the value obtained by dividing the total weight by the preset speed, is obtained according to the total weight and the preset speed, that is, the time consumption, that is, the time that the gas cylinder can be used when it is used at the normal speed, is obtained.
The remaining consumption time is obtained according to the remaining weight and the preset speed, namely, after the problem of leakage of the gas pipeline is eliminated, the consumption speed of the gas in the gas cylinder is carried out according to the preset speed, and at the moment, the remaining weight is divided by the preset speed, and the obtained value is the remaining consumption time, namely, the time for which the remaining gas can be used.
And the time of the gas cylinder is obtained at the same time and is used as the use time, namely the time of the gas in the gas cylinder, the obtaining mode can record the time through an electronic timing device, and then the actual use time is obtained according to the residual consumption time and the use time, namely the value obtained by adding the residual consumption time to the use time is the actual use time, namely the time of judging how long the residual gas can be used.
Then, the initial use time of the gas cylinder is acquired, and then the estimated use time is acquired according to the initial use time and the estimated consumption time, namely, the value acquired by adding the initial use time and the estimated consumption time is the estimated use time.
The time difference is then obtained according to the estimated time of use and the actual time of use, which may be less than the estimated time of use due to leakage of the gas, and the difference obtained by subtracting the actual time of use from the estimated time of use is the time difference.
And finally, outputting a time difference value, and reminding related personnel according to the time difference value, so that the related personnel can replace the gas cylinder in time according to the time difference value, and the normal use of the oven is ensured as much as possible.
