[0002] At present, the popularity of gas stoves is increasing, and users are paying more and more attention to the convenience of using gas stoves. The gas stoves currently on the market are generally divided into liquefied gas stoves and natural gas stoves (liquefied gas stoves are supplied by liquefied gas tanks, and natural gas stoves are supplied by municipal pipelines).

[0003] Users of LPG stoves may encounter some issues. They only know when the liquefied gas in the tank is depleted, making it inconvenient to replace the tank during cooking and affecting cooking progress and results. Natural gas stoves do not encounter these issues, but problems such as gas line blockages may affect cooking progress and results. These issues result in a poor user experience when using a gas stove, as users cannot promptly determine the gas supply status of the stove. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the gas supply status of the gas stove cannot be known in time, which affects the user's cooking progress and cooking effect, and provide a gas stove and its gas supply status detection method, system and storage medium.

[0028] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0029] Example 1

[0030] This embodiment provides a method for detecting the gas supply status of a gas stove. Figure 1 , the gas supply status detection method of the gas stove includes:

[0031] S101: Determine the ignition sound frequency and ignition duration of the gas stove.

[0032] Specifically, when the gas stove is in use, the user turns the knob to turn on the gas stove. When the knob is turned, a "tick-tick" sound is usually heard. After several "tick-tick" sounds, a "puff" sound is heard at the moment the flame is generated. The "puff" sound is regarded as the ignition sound. The ignition sound frequency F determined in this step is n and ignition duration T n It is obtained through the sound collection device and the controller. The ignition duration is the time from the start of the "puff" sound to the end of the "puff" sound, and the ignition sound frequency F is determined. n and ignition duration T n The data collected can be the data collected when the user ignites the stove this time, or the data collected when the user used the stove previously. The sound collection device is usually installed at the stove, but those skilled in the art will understand that the installation location is not limited to the stove.

[0033] S102: If the ignition sound frequency falls within a preset ignition sound frequency band, it is determined to be a valid ignition.

[0034] Specifically, the ignition sound frequency F determined in step S101 is determined. n Whether it falls within the preset ignition sound frequency band, that is, judging whether F n Does F satisfy x ≤F n ≤F y , F x to F yIf the ignition sound frequency band is within the ignition sound frequency range, then the ignition is determined to be effective. If not, then the ignition is determined to be invalid, and the process returns to step S101 to collect the ignition sound frequency and ignition duration of the gas stove.

[0035] S103: Determine whether the ignition duration of the effective ignition is greater than or equal to an ignition duration threshold: if so, determine that the gas supply state of the gas stove is a gas shortage state.

[0036] Specifically, the ignition duration T of the effective ignition determined in step S102 is determined. n Is it greater than or equal to the ignition duration threshold T x If yes, the ignition duration for effective ignition is abnormal. At this point, the gas stove is determined to be in a gas-deficient state. If no, the gas supply is normal. Gas supply status is divided into normal and gas-deficient states. Normal means the gas supply to the stove is normal; gas-deficient states indicate an abnormal gas supply.

[0037] For example, when a user uses a liquefied gas stove (supplied by a liquefied gas tank), the sound frequency of the ignition sound of the liquefied gas stove and the corresponding ignition duration are determined. It is determined whether the determined liquefied gas stove ignition sound frequency falls within the preset ignition sound frequency band. If so, it is determined that the determined liquefied gas stove ignition is a valid ignition. It is determined whether the ignition duration of the valid ignition is greater than or equal to the ignition duration threshold: if so, the gas supply status of the liquefied gas stove is a gas shortage state. At this time, the cause of the gas shortage may be insufficient liquefied gas in the liquefied gas tank, requiring the user to replace the liquefied gas tank.

[0038] For another example, when a user uses a natural gas stove (supplied by a natural gas pipeline), the frequency of the natural gas stove ignition sound and the corresponding ignition duration are determined. A determination is made as to whether the determined natural gas stove ignition sound frequency falls within a preset ignition sound frequency band. If so, the determined natural gas stove ignition is considered valid. A determination is made as to whether the valid ignition duration is greater than or equal to an ignition duration threshold. If so, the natural gas stove is in a gas-deficient state. This gas-deficient state may be caused by a clogged natural gas pipeline, requiring prompt inspection by the user.

[0039] During the use of the gas stove in this embodiment, the ignition sound frequency is collected by a sound collection device to determine whether it falls within the preset ignition sound frequency band. Various sound-making objects in the environment will produce sounds in different frequency bands. The collected sounds will exist in various frequency bands, including the "puff" sound emitted when the gas stove is ignited. Only the ignition frequencies that fall within the preset ignition sound frequency band need to be analyzed, and sounds in other frequency bands are not analyzed. Based on the above principle, it is determined whether it is a valid ignition. Secondly, after determining that it is a valid ignition, the gas supply status of the gas stove is determined by the duration of the valid ignition. In this way, during the actual use of the gas stove, the user can be promptly informed whether the gas stove's supply status is normal, thereby improving the user experience.

[0040] In an implementable solution, the ignition duration of the effective ignition in step S103 is: an average value of the ignition durations of a preset number of effective ignitions.

[0041] Specifically, assuming that the preset number of times is M, the ignition durations of the M effective ignitions are obtained, and the average of the ignition durations of the M effective ignitions is calculated as the ignition duration of the effective ignition.

[0042] For example, assuming the preset number of times is 4, the ignition sound frequency Fn1 and ignition duration Tn1 of the first ignition, if the ignition sound frequency Fn1 of the first ignition falls within the preset ignition sound frequency band, that is, F x ≤F n1 ≤F y , then the first ignition is effective. The ignition sound frequency Fn2 and ignition duration Tn2 of the second ignition, if the ignition sound frequency Fn2 of the second ignition does not fall into F x to F y , that is, it does not fall within the preset ignition sound frequency band, then the second time is considered an invalid ignition. In the same way, assuming that the third, fourth, and sixth times are judged to be valid ignitions, and the fifth time is invalid ignition. Calculate the average ignition duration of these four (first, third, fourth, and sixth) valid ignitions, T average ,Right now T average As the ignition time T n .

[0043] The above method determines the gas supply status of the gas stove based on the relationship between the average value of the effective ignition duration over a preset number of times and the ignition duration threshold. This improves the accuracy of the status determination during actual use of the gas stove, more accurately and promptly notifying the user of whether the gas stove's supply status is normal, and thus enhancing the user experience.

[0044] In one possible implementation, see Figure 2The steps after determining that the gas supply state of the gas stove is a gas shortage state in step S103 include:

[0045] S104: Send prompt information.

[0046] In an implementable solution, the prompt information is provided through at least one of a display device, a voice playback device, and a terminal device.

[0047] Specifically, when the gas supply status of the gas stove is low on gas, a prompt will be given through at least one of a display device (e.g., an electronic screen display), a voice playback device (e.g., playing a prompt music or playing a prompt message), or a terminal device (e.g., sending a prompt message to a mobile phone or iPad). Those skilled in the art should be aware that the prompt information methods are not limited to the three methods mentioned above, and any method that can indicate the gas supply status of the gas stove falls within the scope of protection of this patent.

[0048] The above method provides a prompt when the gas stove's gas supply status is low, allowing the user to immediately be informed of the low gas supply status. This allows the user to be promptly informed of the normal gas supply status during actual use of the gas stove, allowing the user to immediately be informed of the gas supply status, thereby improving the user experience. Furthermore, those skilled in the art will appreciate that whether to provide prompts when the gas stove's gas supply status is normal, and the frequency of these prompts, will depend on actual circumstances.

[0049] In an implementable solution, the preset ignition sound frequency band and ignition duration threshold are obtained based on test operation data of the gas stove when the gas supply state is normal.

[0050] Specifically, during product development, developers tested the sound frequency and ignition duration thresholds within the preset ignition sound frequency band for both liquefied gas and natural gas stoves under both normal and low-gas conditions. During actual user operation, the system determines whether the actual ignition sound frequency falls within the preset ignition sound frequency band and compares the actual ignition duration with the ignition duration threshold to determine the gas supply status of the stove.

[0051] The above method obtains preset ignition sound frequency bands and ignition duration thresholds for normal and gas-deficient states through pre-shipment testing, which helps accurately prompt when the gas stove's gas supply status is low, allowing the user to immediately know when the gas supply status is low. In this way, during actual use of the gas stove, the user can be promptly informed of whether the gas stove's supply status is normal, allowing the user to immediately know the gas supply status, thereby improving the user experience.

[0052] In an implementable solution, when the gas stove is a liquefied gas gas stove, the remaining amount of liquefied gas in the liquefied gas tank is determined by the ignition duration and the sound frequency.

[0053] For example, during product development for a gas stove, developers tested the ignition duration and sound frequency of LPG tanks of different specifications at varying levels of remaining capacity. When users actually used the stove, they compared the actual ignition sound frequency and duration with the ignition duration and sound frequency of LPG tanks of corresponding specifications at varying levels of remaining capacity, thereby determining the remaining LPG level in the connected tank.

[0054] For another example, for different specifications of liquefied gas tanks, by selecting multiple groups of liquefied gas tanks with different residual amounts of liquefied gas, the "F x to F y "Frequency band, that is, the ignition duration that falls within the preset ignition sound frequency band is sampled and plotted into a curve to calculate the relationship between the remaining amount of the liquefied gas tank and the ignition duration. For example, every 5% of the remaining amount is sampled in a frequency band in "F x to F y The data point of the ignition duration "puff" is calibrated through the 21 sampling points between 0% and 100%, and a curve is drawn to calculate the relationship between the ignition duration and the liquefied gas remaining in the liquefied gas tank. It should be understood by those skilled in the art that in addition to drawing a curve, other methods that can represent the corresponding relationship fall within the scope of this application.

[0055] When the gas stove is a liquefied gas stove, the above method can be used to accurately determine the remaining liquefied gas level in the liquefied gas tank connected to the gas stove by obtaining the ignition duration and sound frequency at different remaining levels of liquefied gas tanks of different specifications through pre-shipment testing, or by plotting a graph. This allows the user to be promptly informed of the remaining liquefied gas level during actual use of the gas stove, allowing the user to be immediately informed of the gas supply status, thereby improving the user experience.

[0056] Example 2

[0057] This embodiment provides a gas supply status detection system for a gas stove. Figure 3 Schematic diagram of the modules of this embodiment is shown. Figure 3 The gas supply status detection system of the gas stove of this embodiment includes:

[0058] The parameter determination module 101 is used to determine the ignition sound frequency and ignition duration of the gas stove.

[0059] Specifically, when the gas stove is in use, the user turns the knob to turn on the gas stove. When the knob is turned, a "tick-tick" sound is usually heard. After several "tick-tick" sounds, a "puff" sound is heard at the moment the flame is generated. The "puff" sound is regarded as the ignition sound. The ignition sound frequency F determined in this step is n and ignition duration T n It is obtained through the sound collection device and the controller. The ignition duration is the time from the start of the "puff" sound to the end of the "puff" sound, and the ignition sound frequency F is determined. n and ignition duration T n The data collected can be the data collected when the user ignites the stove this time, or the data collected when the user used the stove previously. The sound collection device is usually installed at the stove, but those skilled in the art will understand that the installation location is not limited to the stove.

[0060] The effective ignition determination module 102 is configured to determine that the ignition is effective if the ignition sound frequency falls within a preset ignition sound frequency band.

[0061] Specifically, the ignition sound frequency F determined in step S101 is determined. n Whether it falls within the preset ignition sound frequency band, that is, judging whether F n Does F satisfy x ≤F n ≤F y , F x to F y If the ignition sound frequency band is within the ignition sound frequency range, then the ignition is determined to be effective. If not, then the ignition is determined to be invalid, and the process returns to step S101 to collect the ignition sound frequency and ignition duration of the gas stove.

[0062] The state determination module 103 determines whether the ignition duration of the effective ignition is greater than or equal to an ignition duration threshold. If so, it determines that the gas supply state of the gas stove is a gas shortage state.

[0063] Specifically, the ignition duration T of the effective ignition determined in step S102 is determined. n Is it greater than or equal to the ignition duration threshold T x If yes, the ignition duration for effective ignition is abnormal. At this point, the gas stove is determined to be in a gas-deficient state. If no, the gas supply is normal. Gas supply status is divided into normal and gas-deficient states. Normal means the gas supply to the stove is normal; gas-deficient states indicate an abnormal gas supply.

[0064] For example, when a user uses a liquefied gas stove (supplied by a liquefied gas tank), the sound frequency of the ignition sound of the liquefied gas stove and the corresponding ignition duration are determined. It is determined whether the determined liquefied gas stove ignition sound frequency falls within the preset ignition sound frequency band. If so, it is determined that the determined liquefied gas stove ignition is a valid ignition. It is determined whether the ignition duration of the valid ignition is greater than or equal to the ignition duration threshold: if so, the gas supply status of the liquefied gas stove is a gas shortage state. At this time, the cause of the gas shortage may be insufficient liquefied gas in the liquefied gas tank, requiring the user to replace the liquefied gas tank.

[0065] For another example, when a user uses a natural gas stove (supplied by a natural gas pipeline), the frequency of the natural gas stove ignition sound and the corresponding ignition duration are determined. A determination is made as to whether the determined natural gas stove ignition sound frequency falls within a preset ignition sound frequency band. If so, the determined natural gas stove ignition is considered valid. A determination is made as to whether the valid ignition duration is greater than or equal to an ignition duration threshold. If so, the natural gas stove is in a gas-deficient state. This gas-deficient state may be caused by a clogged natural gas pipeline, requiring prompt inspection by the user.

[0066] During the use of the gas stove in this embodiment, the ignition sound frequency is collected by a sound collection device to determine whether it falls within the preset ignition sound frequency band. Various sound-making objects in the environment will produce sounds in different frequency bands. The collected sounds will exist in various frequency bands, including the "puff" sound emitted when the gas stove is ignited. Only the ignition frequencies that fall within the preset ignition sound frequency band need to be analyzed, and sounds in other frequency bands are not analyzed. Based on the above principle, it is determined whether it is a valid ignition. Secondly, after determining that it is a valid ignition, the gas supply status of the gas stove is determined by the duration of the valid ignition. In this way, during the actual use of the gas stove, the user can be promptly informed whether the gas stove's supply status is normal, thereby improving the user experience.
