[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely in combination with the drawings. Obviously, the described embodiments are some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0027] At present, the market can detect gas flow through the gas meter to determine whether it is leaking. For example, two gas flow thresholds Q1, Q2 can be set on the gas meter, wherein Q1 represents a trace leakage threshold (less than the gas flow under the minimum power of a single gas device), and Q2 represents a pipe burst threshold (much greater than the total gas flow under the maximum power of all gas devices in the user's home). When 0<Q<Q1, the current total gas flow is less than the gas flow under the minimum power of a single gas device, indicating that the gas device is not working, and the existing gas flow can only come from gas leakage, indicating that gas leakage occurs. When Q2<Q, the current total gas flow has exceeded the pipe burst threshold, indicating that there is a pipe burst.

[0028] However, the above method of detecting gas flow through the gas meter can only detect the upper and lower thresholds of the gas device, and can only detect trace gas leakage when the gas device is not working or device pipe burst, and cannot detect gas leakage when the gas device is working normally or severe gas leakage when the gas device is not working, so the application scenario is relatively narrow.

[0029] Therefore, the kitchen gas detection device and system provided by the embodiment of the present application can compare the total gas flow data detected by the gas total meter with the gas flow data of each gas device, so as to more accurately detect whether there is gas leakage in the kitchen, and the application scenario is more extensive.

[0030] In order to facilitate the understanding of the embodiment, first, a kitchen gas detection device disclosed by the embodiment of the present application is introduced in detail.

[0031] Embodiment one:

[0033] The gas total meter is used for detecting total gas flow data and sending the total gas flow data to the central control module; each gas device is used for detecting the gas flow data of the gas device and sending the gas flow data of the gas device to the central control module; the central control module is used for determining that there is gas leakage in the kitchen when the total gas flow data is greater than the sum of the gas flow data of each gas device and a preset error value.

[0034] The central control module in the embodiment is connected with a gas total meter and at least one gas equipment in the kitchen. The gas total meter can collect total gas flow data of the kitchen and send the total gas flow data to the central control module. Each gas equipment can collect gas flow data of the gas equipment and send the gas flow data of the gas equipment to the central control module.

[0035] In some embodiments, the central control module is an independent module, or the central control module is integrated into the gas total meter. Figure 1 and Figure 2 As shown in the figure, Figure 1 The central control module shown in the figure is an independent module, Figure 2 The central control module shown in the figure is integrated into the gas total meter.

[0036] The embodiment of the utility model provides a kind of kitchen gas detection device, gas total meter detects total gas flow data, and total gas flow data is sent to central control module;Each gas equipment detects the gas flow data of the gas equipment, and the gas flow data of the gas equipment is sent to central control module;When total gas flow data is greater than the sum of the gas flow data of each gas equipment and preset error value, central control module determines that kitchen exists gas leakage situation.This mode, total gas flow data detected by gas total meter can be compared with the gas flow data of each gas equipment, to detect more accurately whether kitchen exists leakage situation, and application scenario is more extensive.

[0037] Embodiment two:

[0038] The embodiment provides another kind of kitchen gas detection device, and the processing mode when kitchen exists gas leakage situation is described.

[0039] In some embodiments, the gas total meter described above is provided with a gas total valve of the kitchen;The gas total meter is also used to close the gas total valve when the kitchen exists gas leakage situation.

[0040] The embodiment can place the gas total valve in the gas total meter, and the gas total meter not only has gas flow detection function to collect total gas flow data of the kitchen, but also can control the disconnection and closure of the gas total valve. Therefore, when the kitchen exists gas leakage situation, the central control module can send the instruction of closing the gas total valve to the gas total meter, and the gas total meter closes the gas total valve based on the instruction, to prevent gas leakage.

[0041] Also can see Figure 3 As shown in the figure, a connection relationship between a kitchen gas detection device and a range hood, and Figure 4 As shown in the figure, another connection relationship between a kitchen gas detection device and a range hood, the central control module 12 is also electrically connected with the range hood 3 in the kitchen. Among them, Figure 3 The central control module shown in the figure is an independent module,Figure 4 The central control module is integrated in the gas total meter.

[0046] The central control module can compare the total gas flow detected by the gas total meter with the gas flow data of each gas device detected by the gas device, thereby more accurately detecting whether there is a gas leakage situation. Meanwhile, after detecting a gas leakage, the central control module can further control the gas total meter to close the gas total valve, the central control module can further control the range hood to timely perform an air exhaust operation on the kitchen, and the central control module can further perform an alarm prompt, thereby eliminating indoor safety hazards.

[0047] Embodiment Three

[0048] The embodiment provides another kitchen gas detection device, and mainly describes a processing mode for judging whether the kitchen has a gas leakage situation, which can be referred to as a schematic diagram of gas detection shown in Figure 5

[0049] As shown in Figure 5 First, the gas detection function is started, the central control module starts to work, and whether there is a gas leakage situation is detected; the gas total meter detects the current total gas flow data Q0, which can be regarded as the total gas flow in the pipeline, and simultaneously sends the detected total gas flow data Q0 to the central control module.

[0050] In some embodiments, the gas total meter is configured to collect total gas flow data in real time, and each gas device is configured to collect gas flow data of the gas device in real time.

[0051] ​The gas flow data and the total gas flow data in the embodiment can be collected by the gas equipment and the gas total meter in real time, so that real-time detection of kitchen gas can be realized. Compared with the method of detecting gas flow by the gas meter in the prior art, which can only detect the trace leakage or the device pipe explosion when the gas equipment is not working, the embodiment can detect whether the gas equipment is working or not, and can also detect the trace leakage or the device pipe explosion, so that the detection range is larger.

[0052] In some embodiments, the central control module is further configured to determine that the kitchen does not have a gas leakage when the total gas flow data is less than or equal to the sum of the gas flow data of each gas equipment and a preset error value.

[0053] As shown in Figure 5 , the central control module detects whether the current total gas flow data Q0 is greater than 0; if Q0 is greater than 0, it means that there is gas flow in the pipeline; if Q0 is not greater than 0, it means that there is no gas flow in the pipeline at this time, and there is no leakage.

[0054] As shown in Figure 5 , if Q0 is greater than 0, each gas equipment 1, 2, 3…n detects the gas flow in its own equipment in real time, and sends the detected gas flow data Q1, Q2, Q3…Qn to the central control module, wherein Q1, Q2, Q3…Qn represent the gas flow consumed by different gas equipment. Wherein, n is the total number of gas equipment.

[0055] In some embodiments, the total gas flow data and the gas flow data do not have threshold limits.

[0056] In the embodiment, when determining whether there is a gas leakage, the sum of the total gas flow data and the gas flow data and the error value is compared. There is no threshold limit for the total gas flow data and the gas flow data. Compared with the method of detecting gas flow by the gas meter in the prior art, which only detects the upper and lower thresholds of the gas equipment, the detection range is larger.

[0057] In some embodiments, the central control module is further configured to determine that the gas flow data of the target gas equipment is 0 when the gas flow data sent by the target gas equipment is not received. If the gas equipment target does not feedback the gas flow data, it means that the target gas equipment is in the shutdown state, and the corresponding gas flow data is 0.

[0058] As shown in Figure 5As shown, the central control module can compare the gas flow, and confirm whether Q0 is greater than Q1+Q2+Q3+…+Qn+Qm, wherein Qm represents an error value reserved when the gas equipment calculates the gas flow; if Q0 is greater than Q1+Q2+Q3+…+Qn+Qm, it indicates that the total gas flow of the gas at this time is greater than the sum of the gas flow of each gas equipment, and it can be inferred that there is additional gas consumption at this time, that is, the gas leakage occurs; if Q0 is not greater than Q1+Q2+Q3+…+Qn+Qm, it indicates that the gas usage is normal;

[0059] If there is no gas leakage, the gas equipment works normally, and then the gas usage can be continuously detected; if there is gas leakage, the central control module can issue a prompt to remind the user to handle it in time; at the same time, the total gas valve is closed to prevent continuous leakage; the exhaust hood is started to exhaust the room, so as to eliminate the safety hazard.

[0060] The above kitchen gas detection device provided by the embodiment of the utility model, when starting the gas detection function, the central control module will first receive the total gas flow data and the gas flow data from the total gas meter and the gas equipment in the user's home respectively, and compare the total gas flow data in the total gas meter with the sum of the gas flow data in each gas equipment to judge whether there is leakage, if there is no leakage, it is determined that the gas equipment works normally; if there is leakage, corresponding measures are taken to eliminate the indoor safety hazard. For example, a prompt is sent to the user, and the total gas valve is closed, and the exhaust hood is started to exhaust, etc.
