Description

Technical Field

[0001] The present invention relates to the field of detection technologies, and in particular, to a flame ion detection device for an integrated stove, an integrated stove, and a control method thereof. Background Art

[0002] As a new type of combined household appliance in recent years, the integrated stove appears in the kitchen. Usually, the igniting stove and the range hood are integrated into one machine. Since the range hood is relatively close to the stove, when a fire breaks out in the pot, the flame will be sucked into the range hood cavity. With the help of the wind, once a fire breaks out inside, serious safety problems will be caused. Therefore, for a reliable integrated stove product, a reliable firewall function must be available.

[0003] To improve the use safety, the existing integrated stoves mainly use NTC temperature sensors to detect whether there is a flame. When the temperature is greater than a certain set value, a signal will be sent to the main control system, and the main control system controls the igniter to perform a flameout operation.

[0004] However, the following technical defects still exist in actual applications:

[0005] The response speed of the temperature sensor is relatively slow. It takes a certain period of high temperature to reach the temperature set value, and the accuracy is relatively low.

[0006] When the ambient temperature of the integrated stove is relatively high, reaching the set value of the temperature sensor and there is no flame, the temperature sensor is prone to false alarms, resulting in false alarms of the firewall and a flameout operation.

[0007] The position where the temperature sensor is installed is easily affected by the wind force of the range hood. The wind force will affect the temperature at the sensor position, resulting in inaccurate temperature detection and inability to reflect the accurate temperature. Summary of the Invention

Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0057] To facilitate the understanding of this embodiment, the application scenarios and design concepts of the embodiments of this application will be briefly introduced below.

[0058] In the prior art, during the process of detecting the firewall flame through a temperature sensor, there are technical problems such as slow response speed, low measurement accuracy susceptible to environmental wind force, and easy false triggering.

[0059] Based on this, the embodiments of this application provide a flame ion detection device for an integrated stove, an integrated stove, and its control method.

[0060] Embodiment 1

[0061] This application provides a flame ion detection device for an integrated stove. The flame ion detection device includes: a flame ion detection mechanism and a wire 3.

[0062] The flame ion detection mechanism is arranged in the air duct of the integrated stove. One end of the flame ion detection mechanism is a detection end, and the other end is a signal output end. The detection end faces the inside of the air duct and is opposite to the smoke exhaust direction. The flame ion detection mechanism is used to detect the ions generated by the flame and convert the detection result into an electrical signal for output.

[0063] One end of the wire is electrically connected to the signal output end of the flame ion detection mechanism, and the other end is electrically connected to the input end of the comparator inside the integrated stove. The wire is used to transmit the electrical signal generated by the flame ion detection mechanism to the comparator.

[0064] Among them, the comparator is located inside the integrated stove. The input end of the comparator is connected to the wire, and the output end is electrically connected to the control unit. The comparator receives the electrical signal from the flame ion detection mechanism, compares it with a preset value, and outputs the result to the control unit.

[0065] In this embodiment, by arranging the flame ion detection mechanism in the air duct and utilizing the electric field effect of the flame, during the use of the integrated stove, if a fire occurs and under the suction of the range hood, the flame is brought to the flame ion detection device to form a current. By detecting the output voltage of the comparator to determine whether a flame is generated, it can achieve instant response, accurate detection, and is not affected by the environment and air flow, is not prone to false alarms, which is beneficial to improving the safety of using the integrated stove. At the same time, through the cooperation among the wire, the comparator, and the control unit, the effective monitoring and control of the flame of the integrated stove are realized, thereby improving the safety and intelligent level of using the integrated stove.

[0066] Combined with the first aspect, the flame ion detection mechanism includes: the first flame ion detection mechanism 2 and the second flame ion detection mechanism 4. Please refer to Figure 1 , both the first flame ion detection mechanism 2 and the second flame ion detection mechanism 4 are strip-shaped structures. The second flame ion detection mechanism 4 is arranged on the inner wall of the glass cover plate 1 of the air duct; the second flame ion detection mechanism 4 is arranged at an interval from the first flame ion detection mechanism 2 and is connected to the first flame ion detection mechanism 2 through a conductive connection member to form a matrix frame structure.

[0067] Among them, the second flame ion detection mechanism 4 is connected to the control unit through a wire 3.

[0068] In this embodiment, by fixing the first flame ion detection mechanism 2 on the inner wall of the glass cover plate 1 of the air duct and adopting a strip-shaped structure, it can better adapt to the internal environment of the air duct and ensure the detection accuracy. The way that the second flame ion detection mechanism is arranged at an interval from the first flame ion detection mechanism and is connected through a conductive connection member ensures the stability of the electrical connection between the two, and at the same time simplifies the overall wiring. Finally, the second flame ion detection mechanism is directly connected to the control unit, so that the collected data can be quickly transmitted to the control unit for analysis and processing, thereby realizing the effective monitoring and timely response to the flame state of the integrated stove.

[0069] Specifically, both ends of the first flame ion detection mechanism 2 have grooves and are made of ferroalloy. The first flame ion detection mechanism 2 is used for flame ion detection and can be installed inside the air duct glass cover plate 1 of the integrated stove by embedding. Both ends of the first flame ion detection mechanism 2 have grooves. One end of the conductive connecting piece 5 made of metal is connected to the groove, and the other end is connected to the second flame ion detection mechanism 4 to form a matrix frame structure, thereby expanding the effective area of flame ion detection.

[0070] Combined with the first aspect, the flame ion detection mechanism includes: a plurality of flame ion detection probes arranged at intervals along a direction perpendicular to the flue gas emission direction, and the signal output end of each flame ion detection probe is electrically connected to the control unit through a wire.

[0071] In this embodiment, the flame ion detection probes are arranged at intervals along a direction perpendicular to the flue gas emission direction, and each probe is responsible for detecting the flame ion signal in a specific area. In this way, multi-point collection of the flame ion signal can be realized, thereby improving the coverage and sensitivity of flame detection. At the same time, each flame ion detection probe is independently connected to the control unit through a wire, ensuring the stability and timeliness of signal transmission, thereby providing more reliable flame state monitoring and safety guarantee for the integrated stove.

[0072] It can be understood that the number of flame ion detection probes can be adjusted according to the cooking area of the integrated stove. As an implementable method, the number of flame ion detection probes corresponding to each cooking area is the same; as another implementable method, the number of flame ion detection probes corresponding to each cooking area is different. It can be understood that as the number of flame ion detection probes increases, the monitored range covered increases, and the number can be selected according to actual needs, which is not limited here.

[0073] As another implementable method, there is one or more flame ion detection probes corresponding to each cooking area, but there is also a first flame ion detection probe 6 corresponding to the position between two cooking areas. At this time, the first flame ion detection probe 6 can be used to detect whether there is a tendency for the flame to spread from this cooking area to the adjacent cooking area.

[0074] Reference Figure 2 As shown, this embodiment includes a first flame ion detection probe 6, five second flame ion detection probes corresponding to the first cooking area, which are respectively marked as 70, 71, 72, 73, 74, and five second flame ion detection probes corresponding to the second cooking area, which are respectively marked as 75, 76, 77, 78, 79.

[0075] Among them, the outer diameter of the wire 3 is 0.61 mm and the material is tinned copper. A plurality of wires 3 are electrically connected to a plurality of flame ion detection probes one by one.

[0076] In this embodiment, multiple flame ionization detection probes are fixed to the fixed seat. It can be understood that the fixed seat should be made of high-temperature resistant plastic to ensure the stability of the flame ionization detection probe during operation.

[0077] Combined with the first aspect, the wire 3 is connected to the input end of the comparator, and the input end of the comparator is connected to the I / O port of the control unit.

[0078] During the use of the integrated range hood, when the flame is ignited and under the suction of the range hood, the flame will be brought to the detection end of the flame ionization detection device. A large number of positive and negative ions will be generated inside the flame. When an external electric field acts on the flame, these positive and negative ions will move directionally under the action of the electric field, thereby generating a current. The generated current is input to the comparator and outputs a level. At this time, the voltage of the comparator is detected to determine whether there is a flame in contact with the flame ionization detection device to determine whether there is a flame.

[0079] Specifically, when there is no flame, the non-inverting input terminal V A of the comparator is greater than the inverting input terminal V B where V A = 5V, V B = 0V. Through the output level of the I / O interface, it is recognized that the output terminal voltage of the comparator = the non-inverting input terminal voltage = 5V. When the inverting input terminal voltage V B = 0V, due to the characteristics of the comparator, when V A > V B , the output terminal voltage Vout = 5V.

[0080] When in contact with the flame, under the action of the externally applied alternating electric field, electrons move towards the metal grounding direction to form a negative voltage. Under the voltage limiting action of the diode, V A = -0.7V. At this time, V A < V B , and the output Vout changes from 5V to 0V, generating a pulse signal. When the flame continues to burn and is in contact with the flame ionization detection device, one or more pulse signals will be generated in a short period of time, as shown in Figure 3 . Among them, higher than the first voltage threshold V1 is regarded as a high level, and lower than the second voltage threshold V0 is regarded as a low level. Generally, V1 ≥ 3.3V, V0 < 0.7V. Within a specified time period, by calculating the proportion of the duration of the low level in the total duration within this time period, the contact degree between the flame and the flame ionization detection device can be determined. Combined with Figure 3 , within the time period of 0 - t n , the contact degree

[0081] In a second aspect, the present application provides an integrated stove, which includes the flame ion detection device as described above.

[0082] In a third aspect, a control method for an integrated stove is applied to the control unit of the above integrated stove. As shown in combination with Figure 4 The method includes:

[0083] S110, obtaining the level data of the I / O port corresponding to the flame ion detection device.

[0084] S120, calculating a first average pulse interval time within a specified detection period based on the level data.

[0085] S130, determining whether the first average pulse interval time is greater than or equal to a preset first time threshold.

[0086] If so, execute step S140; if not, execute step S150.

[0087] S140, controlling the pulse igniter and the solenoid valve of the integrated stove to close, and controlling the range hood to stop running.

[0088] S150, maintaining the current operating state.

[0089] In this embodiment, by real-time monitoring of the flame state and automatically adjusting the operating state of the device according to the monitoring results, the safety and intelligence level of the cooking process are improved.

[0090] Specifically, step S110 obtains the level data from the I / O port corresponding to the flame ion detection device, and these level data reflect the changes in the flame state.

[0091] Subsequently, based on the level data obtained in step S110, the first average pulse interval time is calculated within the specified detection period, and this step is used to quantify the frequency of the flame state change. In this embodiment, the detection period is 1 s, which can be adjusted according to the specific detection accuracy requirements. Here, it is only an example and is not limited.

[0092] After that, the first average pulse interval time calculated in step S120 is compared with the preset first time threshold.

[0093] If the first average pulse interval time is greater than or equal to a preset first time threshold, step S140 is executed to control the integrated stove and the range hood to stop operating, so as to ensure that the cooking device stops in the presence of a flame, thereby ensuring safety. Specifically, the control unit sends a shutdown control instruction to the pulse igniter to control the solenoid valve for gas inlet and outlet to close, so that the gas stove part stops working, ensuring that the gas supply can be cut off in a timely manner in case of an abnormality and preventing potential safety hazards. At the same time, the range hood is turned off to prevent the generated flame from entering the whole machine through the air duct, thereby avoiding serious consequences such as possible equipment damage or fire.

[0094] If the first average pulse interval time is less than the preset first time threshold, it indicates that there is no flame at present, and it is only necessary to ensure that the current operating state continues to operate.

[0095] Combined with the third aspect, there are multiple cooking areas in the integrated stove, and the multiple cooking areas correspond to multiple flame ion detection devices one by one.

[0096] The method includes:

[0097] S210, for each of the cooking areas, obtain the first level data of the I / O port corresponding to the corresponding flame ion detection device.

[0098] S220, calculate the first average pulse interval time of the cooking area based on the first level data.

[0099] S230, determine whether the sum of all the first average pulse interval times is greater than or equal to a preset second threshold.

[0100] If so, steps S240 - S250 are executed; if not, step S260 is executed.

[0101] S240, combine all the first average pulse interval times to determine the first target cooking area with a flame.

[0102] S250, control the pulse igniter and the solenoid valve corresponding to the first target cooking area to close, and control the range hood to stop operating.

[0103] When multiple cooking areas are integrated into the integrated range hood, the multiple cooking areas correspond to multiple flame ionization detection devices one by one, so as to detect the flame in the air duct connected to the corresponding cooking area specifically. Similar to steps S110 - S120, steps S210 - S220 calculate the first average pulse interval time by detecting the first level data of the I / O port. Since the number of cooking areas increases, the data processing amount of comparing the calculated first average pulse interval time with the preset second threshold respectively is relatively large. At this time, the data processing amount can be reduced by summing and comparing with the preset second threshold. If it is less than the preset second threshold, it means that there is no flame in the air duct corresponding to each cooking area. At this time, execute step S260 and continue to run in the current operating state; if it is greater than or equal to the preset second threshold, then compare them separately to determine the first target cooking area where the flame is generated in the corresponding air duct. Subsequently, execute step S250 to turn off the igniter and solenoid valve of the first target cooking area, block the gas supply, and at the same time turn off the range hood to prevent the generated flame from entering the whole machine through the air duct and causing serious consequences such as equipment damage and fire.

[0104] Combined with the third aspect, there is also a target flame ionization detection device corresponding to two adjacent cooking areas.

[0105] At this time, after step S210, it further includes: obtaining the second level data of the I / O port corresponding to the target flame ionization detection device.

[0106] S211, calculate the first average pulse interval time of the cooking area based on the first level data, and calculate the second average pulse interval time of the cooking area based on the second level data.

[0107] S311, determine whether the sum of all the first average pulse interval times and the second average pulse interval times is greater than or equal to the preset second threshold.

[0108] If so, execute steps S411 - S511; if not, execute step S611.

[0109] S411, combine all the first average pulse interval times to determine the second target cooking area where there is a flame.

[0110] S511, adjust the operating state of the second target cooking area according to the comparison relationship between the second average pulse interval time and the preset second time threshold.

[0111] S611, maintain the current operating state.

[0112] Compared with steps S210 - S260, in this embodiment, there is also a corresponding target flame ion detection device between two adjacent cooking areas. Therefore, in the step of obtaining the level data, it is also necessary to obtain the second level data of the I / O port corresponding to the target flame ion detection device, and sum it with the first level data to determine whether there is a second target cooking area with a flame. If not, step S611 can be executed to continue maintaining the current operating state. If so, first locate the specific second target cooking area with a flame, and combine the second level data to determine whether the flame has a tendency to extend to the adjacent cooking area, and make corresponding adjustments for different situations.

[0113] Combined with the third aspect, step S611 includes: If the second average pulse interval time is greater than or equal to the preset second time threshold, control the second target pulse igniter, the second target solenoid valve, and the range hood corresponding to the second target cooking area and the adjacent cooking area to stop operating.

[0114] It can be understood that when the second average pulse interval time is greater than or equal to the preset second time threshold, it means that the flame has a tendency to extend to the adjacent cooking area, or even has extended to the adjacent cooking area. At this time, the pulse igniters and gas valves of these two cooking areas should be closed simultaneously to stop the gas supply, and the range hood should be closed to prevent the generated flame from entering the whole machine through the air duct.

[0115] Combined with the third aspect, step S611 further includes: If the second average pulse interval time is less than the preset second time threshold, control the second target pulse igniter, the second target solenoid valve, and the range hood corresponding to the second target cooking area to stop operating.

[0116] It can be understood that when the second average pulse interval time is less than the preset second time threshold, it means that the flame has no tendency to extend to the adjacent cooking area for the time being. At this time, only the determined second target cooking area needs to be adjusted, the pulse igniter and gas valve of this second target cooking area are closed to stop the gas supply, and the range hood is closed to prevent the generated flame from entering the whole machine through the air duct.

[0117] Fourth aspect, an embodiment of the present application provides an electronic device. Combined with Figure 5 as shown, this electronic device includes a memory 131 and a processor 130. The memory 131 is used to store a computer program, and the processor 130 runs the computer program to enable the electronic device to execute the above - mentioned method.
