Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
There are two control modes of gas stoves in the market at present, one is a stove with a chip program control ignition mode, and the other is a stove without a chip program control ignition mode. The gas stove with the igniter controlled by the chip program is divided into three types: the high-end gas stove has the functions of dry burning prevention and pot detection on the stove head; the middle-end gas stove is provided with a stove head for preventing dry burning; the common gas cooker has no dry burning prevention function and pot detection function.
For a high-end gas stove with a dry burning prevention function and a pot detection function on a stove top, the dry burning prevention probe is used for placing a thermistor inside a metal alloy shell to form an alloy probe, and the alloy probe is used for detecting the temperature of a pot bottom to prevent the dry burning function; a reed switch detection probe is arranged at the lower part of the dry burning prevention probe, and whether a cooker is placed or not is judged to control the firepower of the cooking range, so that safety accidents are prevented.
The detection of preventing dry combustion method needs to obtain a unique voltage value by dividing a specific resistance value of a thermistor in the probe for preventing dry combustion method along with the change of temperature, a chip port calculates a corresponding temperature value by detecting the divided voltage value, and when the temperature value calculated by a chip processor reaches a dry combustion protection value, the chip controls the ventilation of a motor valve of a gas stove through signal output, so that the firepower output is controlled, and the occurrence of dry combustion is prevented.
The pot detection needs to be carried out when the pot is placed on the cooking range, the probe is pressed, the reed switch is connected after the probe is compressed, and the chip detects the voltage change connected at the moment to judge that the pot is placed on the cooking range. When the cooker is taken away, the probe is not pressed and bounces to the original position, the reed switch is turned off, and the chip detects that the voltage on at the moment changes to another state, so that the fact that the cooker is not provided with the cooker is judged.
In addition, the high-end gas stove has high device cost, more electronic devices are arranged on the printed circuit board, 2 probes need 2 chip ports to process data, and 2 probes need 2 sets of related matching hardware circuits. Therefore, failure rates are higher and costs in terms of quality and after-market are increased.
To sum up, the existing high-end gas stove has the following defects: the electrical appliance structure is provided with two probes, one is an anti-dry heating probe and the other is a pot detection probe, and the cost of parts is high. The devices have many production problems and complex installation process. Each probe needs to have a matched electronic circuit to process the received data, so that the electronic devices are more, the fault rate is high, and the after-sale maintenance cost is high. The current temperature probe is only used as dry burning protection and has no function of detecting the quantity of food.
Based on the above, the detection method, the device, the equipment and the storage medium of the gas stove provided by the embodiment of the application can realize the pan detection and the dry burning prevention detection through one temperature probe, namely, the dry burning prevention function and the pan detection function are realized by using only one temperature probe instead of the original temperature detection probe and the pan detection probe, so that the cost and the failure rate of the gas stove are reduced.
For the convenience of understanding the present embodiment, a method for detecting a gas stove disclosed in the embodiment of the present application will be described in detail.
Embodiment one:
the embodiment of the application provides a detection method of a gas stove, wherein the gas stove is provided with a temperature probe, and the detection method of the gas stove is shown in a flow chart of the detection method of the gas stove in FIG. 1, and comprises the following steps:
step S102, acquiring a temperature value of the gas stove through a temperature probe.
The gas stove in the embodiment can be provided with only one temperature probe, and the temperature probe can acquire the temperature value of the gas stove.
Step S104, judging whether a cooker is arranged on the gas stove or not based on the temperature value.
In this embodiment, the pan detection can be performed according to the temperature value acquired by the temperature probe, and whether the pan is arranged on the gas stove is judged. For example: in this embodiment, the slope of the temperature and time may be calculated according to the temperature value, where a higher slope indicates that a pot is disposed on the gas stove, and a higher slope indicates that no pot is disposed on the gas stove.
Step S106, and/or judging whether the gas stove has dry burning of the cookware or not based on the temperature value.
In the embodiment, the anti-dry burning detection can be performed according to the temperature value acquired by the temperature probe, and whether the cooker is dry burned or not is judged. For example: the higher temperature value can be regarded as the dry burning of the cookware, and the lower temperature value can be regarded as the dry burning of the cookware.
The embodiment of the application provides a detection method of a gas stove, which comprises the steps of collecting a temperature value of the gas stove through a temperature probe; judging whether a cooker is arranged on the gas stove or not based on the temperature value; and/or judging whether the gas stove has dry burning of the cookware or not based on the temperature value. In the mode, the pot detection and the dry burning prevention detection can be realized through one temperature probe, and the cost and the failure rate of the gas stove are reduced.
Embodiment two:
the present embodiment provides another method for detecting a gas stove, which is implemented on the basis of the above embodiment, referring to a flowchart of another method for detecting a gas stove shown in fig. 2, where the method for detecting a gas stove in this embodiment includes the following steps:
step S202, acquiring a temperature value of the gas stove through a temperature probe.
In some embodiments, the voltage value may be determined by a thermistor within the temperature probe; determining the resistance of the thermistor based on the voltage value; and determining the temperature value of the gas stove based on the resistance value of the thermistor.
In this embodiment, the voltage value at one end of the thermistor can be collected in real time through the chip port, the resistance value of the thermistor at the moment is calculated, and then the resistance value of the thermistor is converted into the temperature value of the corresponding gas stove through the resistance thermometer of the thermistor.
Step S204, judging whether a cooker is arranged on the gas stove or not based on the temperature value.
For pot detection, in some embodiments, multiple temperature values of the gas cooker may be acquired by the temperature probe during combustion of the gas cooker with the same fire. The pan detection in this embodiment needs to satisfy the combustion process of the gas stove at the same fire, and the pan detection is performed according to the collected multiple temperature values, so as to determine whether the pan is on the cooking range of the gas stove. In this embodiment, the following 2 pot detection modes are provided:
(1) In the same fire combustion process, the temperature of the temperature probe can rise along with the change of time, and the temperature rise is slow in the state of having a cooker; in the state without the pot, the temperature rises faster. Therefore, the embodiment can set a slope threshold value of temperature and time, and judge whether the cooker is placed on the gas stove or not by comparing the slope of temperature collected in real time and time with the threshold value.
In some embodiments, the amount of change in the temperature value of the first target duration may be determined based on a plurality of temperature values; if the variation is smaller than a preset second threshold value, judging that a cooker is arranged on the gas stove; if the variation is greater than or equal to the second threshold, judging that no cookware is arranged on the gas stove.
Therefore, the present embodiment can calculate the amount of change in the temperature value within the same fire power and the same time (i.e., the first target period of time) after the gas range is turned on. The two states of the pot and the non-pot are different in temperature variation of the temperature probe heated under the same firepower and the same time, and whether the pot is placed on the cooking range can be judged according to the temperature variation.
Referring to a schematic diagram of a mode of detecting a pot shown in fig. 3, a stove is started by ignition, heating is performed by using N-level fire, a temperature probe monitors a temperature value Temp of a pot bottom in real time, and data is transmitted to a main controller of a gas stove. The main controller judges whether the temperature variation DeltaTemp_1 after the first target Time DeltaTime_1 is smaller than a preset second threshold Tp_1 (wherein the second threshold corresponds to the fire of the gas stove, the second threshold setting of each grade of fire is different, the fire is small, the second threshold setting, the fire is large, and the second threshold setting is large).
If delta Temp_1 is less than Tp_1, the temperature change is small, a cooker is arranged on the cooking range, and the cooking range continues to heat and cook; if DeltaTemp_1 > =Tp_1, the temperature change is large, no cooker is arranged on the kitchen range, and the master controller adjusts the minimum fire and prompts no cooker alarm.
And detecting the temperature change of the probe in real Time in the operation process of the kitchen range, and calculating whether the temperature change quantity DeltaTemp_n in the first target Time DeltaTime_n is smaller than a preset second threshold Tp_n or not in a rolling mode (the temperature threshold of each fire is different, the fire is small, the threshold is low, and the fire is large and the threshold is large).
If delta Temp_n is smaller than Tp_n, the temperature change is small, a cooker is arranged on the cooking range, and the cooking range continues to heat and cook until the cooking is finished; if DeltaTemp_n > =Tp_n, the temperature change is large, the cookware on the cooking range is moved away, and the master controller adjusts the minimum fire and can prompt a pot moving alarm.
(2) In the same fire burning process, a temperature interval, such as 50-100 deg.c, is selected, and the time period required for heating from 50 deg.c to 100 deg.c, i.e. the first target temperature value is counted. And setting a third threshold value, comparing the counted time length with the set third threshold value, and judging whether the cooker is placed on the gas stove or not. And normally judging that the pot is in the presence when the time length is longer than the third threshold value, and judging that the pot is not in the absence when the time length is shorter than or equal to the third threshold value.
In some embodiments, a duration for which the temperature value varies by the first target value may be determined based on the plurality of temperature values; if the time length is greater than a preset third threshold value, judging that a cooker is arranged on the gas stove; if the duration is less than or equal to the third threshold value, judging that no cooker is arranged on the gas stove.
Therefore, the embodiment can count the used time period under the same fire power and the same temperature rise after the gas stove is started. The two states, with and without cookware, are different for the duration that the temperature probe takes to reach the same set temperature at the same fire. So as to judge whether a cooker is placed on the cooking range.
Referring to the schematic diagram of another mode of pan detection shown in fig. 4, the stove is started by ignition, heating is performed by using N-level fire, the temperature probe monitors the temperature value Temp of the pan bottom in real time, and data is transmitted to the main controller. The main controller judges whether the required heating Time DeltaTime_1 recorded every DeltaTemp_1 (i.e. the temperature value changes by the first target value) is larger than a preset third threshold Tp_1 (wherein the third threshold corresponds to the fire of the gas stove. The third threshold setting of each grade of fire is different, the general fire is small, the third threshold setting is large, the fire is large, and the third threshold setting is small).
If delta Time_1> Tp_1, the heating Time required at the moment is long, a cooker is arranged on the cooking range, and the cooking range continues to heat and cook; if ΔTime_1< = Tp_1, the heating Time required at the moment is short, no cooker is arranged on the cooking range, and the master controller adjusts the minimum fire and prompts no-cooker alarm.
The method comprises the steps of detecting the temperature change of a probe in real Time in the operation process of the kitchen range, calculating whether heating Time DeltaTime_n required by a certain temperature value in a first target value DeltaTemp_n is larger than a preset third threshold Tp_n or not in a rolling mode (the third threshold setting of each grade of firepower is different, the firepower is small, the third threshold setting is large, the firepower is large, and the third threshold setting is small).
If delta Time_n > Tp_n, the heating Time required at the moment is long, a cooker is arranged on the cooking range, and the cooker continues to heat and cook until the cooking is finished; if Δtime_n < = tp_n, the heating Time required at the moment is short, the cookware on the cooking range is moved away, and the master controller adjusts the minimum fire and prompts pot moving alarm.
See the schematic of one temperature profile shown in fig. 5 and the schematic of another temperature profile shown in fig. 6. FIG. 5 shows the temperature profile for a temperature probe with and without cookware to heat to 200℃with the same fire. Fig. 6 shows a graph of the temperature profile of the probe during operation, with the pot placed and the pot removed.
When the pot is heated, the energy of the probe is absorbed by the pot, and the temperature rises slowly; under the condition of no pot, the probe is radiated by the flame, and the temperature rises faster. Therefore, the temperature rise slope with time is larger than that of the pot under the condition of no pot in the comparison of the pot with the pot without the pot under the heating condition. The embodiment can judge whether the cooker is present or not according to the slope of the temperature rise.
In addition, in the two states of the pot and the non-pot, the slope of the temperature change of each gear (the fire adjustment size) in the two states of the pot and the non-pot can be tested, the second threshold and the third threshold are determined based on the slope, and a program is written in, so that judgment of various states is more conveniently carried out. The temperature measurement of the kitchen range is more specific and careful, and the intelligent kitchen electric temperature measurement is more comprehensive.
The embodiment of the application provides a control method for detecting a pot by a temperature probe, and a gas stove can accurately judge whether a pot is placed on the stove or removed in the working process in operation. By the control method of the temperature detection cookware, one detection pot probe can be omitted, the material cost is saved, and the working manufacturing and warehouse storage cost of the whole machine installation is saved. The circuit hardware circuit corresponding to the probe can be reduced, and the cost of electronic elements and the manufacturing cost are reduced. The method has the advantages of reduced materials, reduced failure rate, reduced after-sales maintenance cost and improved brand public praise.
Step S206, and/or judging whether the gas stove has dry burning of the cookware based on the temperature value.
In some embodiments, if the temperature value is greater than a preset first threshold value, judging that the cooker dry burning occurs in the gas stove; if the temperature value is smaller than or equal to the first threshold value, judging that the cooker dry burning does not occur in the gas stove.
For the dry heating prevention detection, a first threshold (for example, 280 ℃) can be preset, and if the temperature value is greater than 280 ℃, the occurrence of dry heating of the cooker can be judged; if the temperature value is less than or equal to 280 ℃, it can be determined that no dry heating of the cookware occurs, i.e. the temperature value is in the normal working temperature range.
Step S208, determining the weight of the food materials of the cookware based on the plurality of temperature values.
In this embodiment, the amount of the weight of the food material can be determined by the change of the temperature in the intelligent mode of cooking the specified food material. The more food materials are when the same type of food is heated, the slower the temperature rise, and the longer the heating time. Therefore, the amount of food material can be determined from the temperature rise curve.
In some embodiments, the amount of change in the temperature value of the second target duration may be determined based on the plurality of temperature values; determining the weight of food materials of the cookware based on the variable quantity; wherein, the variable quantity is inversely related to the weight of the food material of the cooker.
The second target duration may be the same as or different from the first target duration, which is not limited in this embodiment. The gas stove in this embodiment provides the same fire power, the same burning time (i.e., the second target duration), the same energy Q value, and the energy absorbed by the food is: q=m×c×Δt, and the supplied energy Q value is the same as seen from the above formula; the food materials are the same, and the specific heat capacity value C is the same. The weight m of the food material is inversely proportional to the change delta T of the temperature value, and the more the weight m of the instant food material is, the smaller the temperature rise change is; conversely, the larger the temperature rise variation. Therefore, the embodiment can set the same heating time, i.e. the same energy Q value, and observe the temperature change delta T converted by the thermistor so as to judge the quantity of the food.
In some embodiments, the duration of the temperature value change second target value may be determined based on a plurality of temperature values; determining the weight of food materials of the cooker based on the time length; wherein, the time length is positively correlated with the weight of the food material of the cooker.
The second target value may be the same as or different from the first target value, and this embodiment is not limited thereto.
