[0002] Range hoods are essential appliances for removing cooking fumes during daily cooking; integrated range hood and cooktop combo systems have become increasingly popular in recent years.

[0003] Furthermore, existing range hood and cooktop linkage products use non-contact temperature measurement of the pot and burner above the cooktop to attempt to determine the cooktop's on / off status based on temperature changes.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0050] Based on the technical feature that the transmission direction of sound waves is related to the flow velocity of fluids, this application provides a method for real-time detection of the gas flow rate of a stove, and then real-time control of the range hood and stove linkage according to the firepower status of the stove.

[0051] Please see Figure 1 The illustration shows a schematic diagram of a range hood and cooktop linkage system provided in an embodiment of this application. The system may include: a range hood 01, a cooktop 02, an energy detection module 03, and a processing module 04; the processing module 04 is communicatively connected to the range hood 01 and the energy detection module 03 respectively; the energy detection module 03 is communicatively connected to the cooktop 02.

[0052] Optionally, the gas pipe of the stove is provided with a sound wave emitting end 021 and a sound wave receiving end 022; the sound wave emitting end and the sound wave receiving end are located on opposite sides of the inner wall of the gas pipe.

[0053] Furthermore, the energy detection module can be used to collect the acoustic energy of the acoustic wave transmitter 021 and acoustic wave receiver 022 set in the stove, and send each acoustic wave energy to the processing module;

[0054] In one example, the acoustic receiver 022 may include a first receiver and a second receiver; at least one of the first receivers receives the acoustic waves emitted by the acoustic receiver downstream of the gas flow direction.

[0055] Among them, the first receiving end, located downstream of the gas flow direction, receives greater acoustic energy than the second receiving end when the gas flow rate in the gas pipe is greater than the preset flow rate threshold.

[0056] Correspondingly, the energy detection module 03 can be used to collect the first sound wave energy received by the first receiving end and the second sound wave energy received by the second receiving end, and send the first sound wave energy and the second sound wave energy to the processing module 04.

[0057] The processing module 04 can be used to determine the target energy difference between the received sound wave energy and the received first sound wave energy and second sound wave energy, and to analyze the gas flow based on the target energy difference and the target energy threshold to obtain the target gas quantity corresponding to the target energy difference; then, to adjust the operating mode of the range hood according to the target gas flow.

[0058] Range hood 01 can receive adjustment commands sent by the processing module to adjust the operating mode of the range hood.

[0059] In this embodiment of the application, under a certain scenario, the relationship between the energy difference and the gas flow rate is positively correlated. The larger the energy difference, the larger the gas flow rate and the greater the gas velocity, and correspondingly, the stronger the firepower of the stove.

[0060] In some exemplary embodiments, such as Figure 2 The diagram shows a schematic representation of the arrangement structure of a sound wave emitting end and a sound wave receiving end inside a gas pipe according to an embodiment of this application. Figure 1 The specifics are as follows:

[0061] The figure shows a cross-sectional view of the gas pipe, with the sound wave emitting end A and the sound wave receiving end distributed on the inner wall of opposite sides of the gas pipe along the central axis of the gas pipe.

[0062] Furthermore, the second receiving end B and the first receiving end C are symmetrically arranged along the perpendicular line between the transmitting end A and the inner wall of the gas pipe, and the angle α formed between each of the two receiving ends and the sound wave transmitting end is equal.

[0063] In one example, angle α is less than or equal to 60°.

[0064] In this example, the sound wave emitting end A can emit sound waves in a direction perpendicular to the inner wall of the gas pipe, so that when the gas valve is not activated, the sound energy received by the second receiving end B and the first receiving end C is equal. That is, when the gas flow rate is 0, the energy difference received by the second receiving end B and the first receiving end C is 0.

[0065] Correspondingly, as the gas valve is activated and the gas flow rate increases, the energy difference received by the second receiver B and the first receiver C increases.

[0066] That is, when the gas valve is activated, the target energy difference is the difference between the sound wave energy received by the first receiver C and the sound wave energy received by the second receiver B.

[0067] In other exemplary embodiments, such as Figure 3 The diagram shows a schematic representation of the arrangement structure of a sound wave emitting end and a sound wave receiving end inside a gas pipe according to an embodiment of this application. Figure 2 The specifics are as follows:

[0068] The figure shows a cross-sectional view of the gas pipe, with the transmitting end A and the sound wave receiving end distributed on the inner wall of opposite sides of the gas pipe along the central axis of the gas pipe.

[0069] Furthermore, the line connecting the second receiving end B and the sound wave emitting end A is perpendicular to the inner wall of the gas pipeline, the first receiving end C is located downstream of the gas flow direction, and the included angle β between the first receiving end C and the sound wave emitting end A can be 10°-70°.

[0070] In this example, transmitter A can emit target sound waves along the direction perpendicular to the inner wall of the gas pipeline or in a direction inclined toward receiver C; the sound wave energy received by the first receiver C is always greater than the sound energy received by the second receiver B; however, when the gas valve is activated, the difference in sound wave energy received by the first receiver C and the second receiver B increases with the increase of gas flow rate.

[0071] That is, when the gas valve is activated, the target energy difference is the difference between the first difference between the sound wave energy received by the first receiver C and the sound wave energy received by the second receiver B and the initial difference; the initial difference can be the difference between the sound wave energy received by the first receiver C and the sound wave energy received by the second receiver B when the gas valve is not activated.

[0072] Please refer to Figure 4The diagram illustrates a flowchart of a method for linking a range hood and stove according to an embodiment of this application. This specification provides the operational steps described in the embodiments or flowchart, but based on conventional or non-inventive methods, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many, and does not represent the only possible execution order. The method for linking a range hood and stove can be executed according to the order shown in the embodiments or drawings. Specifically, as shown... Figure 4 As shown, the method, applied to range hoods and cooktops, includes:

[0073] S401, acquire the first sound wave energy received by the first receiving end and the second sound wave energy received by the second receiving end;

[0074] In this embodiment of the application, the first acoustic energy can be the acoustic energy actually received by the first receiving end; the second acoustic energy can be the acoustic energy actually received by the second receiving end.

[0075] In some exemplary embodiments, the first acoustic energy received by the first receiver and the second acoustic energy received by the second receiver can be obtained based on the energy detection module.

[0076] S403, based on the target energy difference between the first sound wave energy and the second sound wave energy, and the target energy threshold, analyze the gas flow rate to obtain the target gas flow rate corresponding to the target energy difference;

[0077] In this embodiment, the target energy threshold is associated with relative position information; the relative position information represents the positional relationship between the first receiver and the sound wave transmitter, and the positional relationship between the second receiver and the sound wave transmitter.

[0078] The preset energy difference is positively correlated with the preset gas flow rate. Specifically, the preset energy difference is positively correlated with the preset gas flow rate, and the preset gas flow rate is positively correlated with the preset gas flow rate. Therefore, it can be concluded that the preset energy difference and the preset gas flow rate are positively correlated.

[0079] The target energy threshold may include a first energy threshold, a second energy threshold, a third energy threshold, and a fourth energy threshold; wherein the fourth energy threshold is greater than the third energy threshold, the third energy threshold is greater than the second energy threshold, and the second energy threshold is greater than the first energy threshold. As an example,

[0080] As an example, if the first receiving end and the second receiving end are symmetrically arranged relative to the sound wave emitting end, and the gas valve is not activated, the sound wave energy received by the first receiving end is equal to the sound wave energy received by the second receiving end. Correspondingly, the first energy threshold can be 0.

[0081] When the first and second receiving ends are asymmetrically positioned relative to the sound wave emitting end, if the gas valve is not activated, the sound wave energy received by the receiving end downstream of the gas flow is greater than that received by the receiving end upstream of the gas flow. Correspondingly, the initial difference in sound wave energy received by the two receiving ends can be defined as the first energy threshold. The initial difference can refer to the absolute value of the difference between the sound wave energy received by the first receiving end and the sound wave energy received by the second receiving end when the gas valve is not activated. The initial difference can be 0 or a natural number greater than 0.

[0082] Optionally, for the method of obtaining the target energy difference, the absolute value of the difference between the first sound wave energy and the second sound wave energy can be determined as the target energy difference.

[0083] Based on the target energy difference and the target energy threshold, the gas flow rate is analyzed to obtain the target gas flow rate corresponding to the target energy difference;

[0084] In some exemplary embodiments, the target energy difference can be compared with a second energy threshold, or the target energy threshold can be compared with a first energy threshold and a second energy threshold respectively; the working state of the stove can be determined, which may include an active state, an inactive state, and a fault state;

[0085] In one example, if the target energy difference is greater than a first energy threshold and less than or equal to a second energy threshold, the stove is determined to be in an off state. Furthermore, the first gas flow rate corresponding to the stove being in an off state can be determined as the target gas flow rate. As an example, the first gas level can characterize that the stove is not turned on; when the stove is in an off state, the first gas flow rate can be 0.

[0086] By detecting the target energy difference in real time, the working status of the stove can be quickly determined. If it is determined that the stove is not turned on, there is no need to compare the target energy difference with the third and fourth energy thresholds, which simplifies the data processing steps.

[0087] In another example, if the target energy difference is greater than the second energy threshold, the stove is determined to be in the start state. Further, if the stove is in the start state, the target energy difference is compared with the third energy threshold, and / or the target energy difference is compared with the fourth energy threshold to obtain an energy comparison result. Based on the energy comparison result, the target gas flow rate is determined.

[0088] Specifically, when the stove is in the activated state, a first correspondence between a preset energy threshold and a preset gas rating, and a second correspondence between the preset gas rating and a preset gas flow rate can be obtained; furthermore, based on the energy comparison results, determining the target gas flow rate may include:

[0089] Based on the energy comparison results, the target gas grade corresponding to the target energy difference is determined from the first correspondence; then, based on the target gas grade, the target gas flow rate corresponding to the target gas grade is determined from the second correspondence.

[0090] As an example, when the target energy difference is greater than or equal to the third energy threshold and less than or equal to the fourth energy threshold, the second gas level corresponding to the target energy difference is selected from the first correspondence; based on the second gas level, the second gas flow rate corresponding to the second gas level is selected from the second correspondence, and then the second gas flow rate is determined as the target gas flow rate. Here, the second gas level can characterize that the stove's flame intensity is medium; as an example, the second gas level can refer to a medium flow rate level; correspondingly, the second gas flow rate can refer to a medium gas flow rate.

[0091] As an example, when the target energy difference is greater than the fourth energy threshold, the third gas level corresponding to the target energy difference is selected from the first correspondence; based on the third gas level, the third gas flow rate corresponding to the third gas level is selected from the second correspondence, and then the third gas flow rate is determined as the target gas flow rate. Here, the third gas level can characterize that the stove's flame is at high power; as an example, the third gas level can refer to a high flow rate level; correspondingly, the third gas flow rate can refer to a high gas flow rate.

[0092] As an example, when the target energy difference is less than the third energy threshold, the fourth gas level corresponding to the target energy difference is selected from the first correspondence; based on the fourth gas level, the fourth gas flow rate corresponding to the fourth gas level is selected from the second correspondence, and then the fourth gas flow rate is determined as the target gas flow rate. Here, the fourth gas level can characterize that the stove's flame is low; as an example, the fourth gas level can refer to a low flow rate level; correspondingly, the fourth gas flow rate can refer to a low gas flow rate.

[0093] By comparing the target energy difference with the third and / or fourth energy thresholds when the stove is in the start-up state, the target gas quantity corresponding to the target energy difference can be quickly and accurately determined, thus obtaining the stove's firepower status.

[0094] In another example, if the target energy difference is less than a first energy threshold, the stove can be determined to be faulty; furthermore, a maintenance reminder can be issued. As an example, this could be due to a faulty energy detection module within the stove's gas pipe.

[0095] In some exemplary embodiments, the correlation between a preset energy difference and the gas flow rate can be obtained; the comparison result between the target energy difference and the target energy threshold can be determined; based on the comparison result, the target correlation corresponding to the target energy difference can be determined from the correlation; the target gas flow rate can be obtained by analyzing the target energy difference and the target correlation; and the target gas flow rate can be determined based on the inner diameter of the gas pipe and the target gas flow rate.

[0096] S405 adjusts the operating mode of the range hood according to the target gas flow rate.

[0097] In the embodiments of this application, the operating mode of the range hood can characterize the operating mode of the upper fan of the range hood; as an example, the operating mode may include a low power consumption operating mode and a normal power consumption operating mode.

[0098] In some exemplary embodiments, the operating status of the fan on the range hood can be obtained; wherein the operating status may include an on state and an off state.

[0099] Correspondingly, adjusting the operating mode of the range hood according to the target gas flow can include:

[0100] Adjust the fan's operating mode according to the operating status and target gas volume.

[0101] In one example, when the operating status is "on" and the target gas volume is greater than a preset flow threshold, the first target level corresponding to the target firepower is obtained; the fan's operating mode is then adjusted to the first target level. Here, the preset flow threshold can refer to the gas flow threshold corresponding to the stove being off. "Operating status is on" and the target gas volume is greater than the preset flow threshold indicates that both the fan and the stove are on.

[0102] By determining the fan speed corresponding to the target gas volume based on the target gas volume while the fan is on, and then adjusting the fan speed, the fan can be adjusted quickly.

[0103] In another example, the fan is turned off when the operating status is "on" and the target gas volume is less than or equal to a preset flow threshold. Here, "on" and "target gas volume less than or equal to the preset flow threshold" indicate that the fan is on and the cooktop is off. Correspondingly, the fan is in a low-power operation mode at this time.

[0104] In another example, when the operating status is off and the target gas volume is greater than a preset flow threshold, the fan is started, and the second target setting corresponding to the target gas volume is obtained; furthermore, the fan's operating mode is adjusted to the second target setting. Here, the operating status being off and the target gas volume being greater than the preset flow threshold indicates that the fan is off and the stove is on. Correspondingly, the fan is in normal power consumption operation mode at this time.

[0105] By determining the fan speed corresponding to the target gas volume based on the target gas volume when the fan is not turned on, and then starting the fan and adjusting the fan speed, the fan can be accurately adjusted.

[0106] In another example, the fan remains operational when it is in an off state and the target gas flow rate is less than or equal to a preset flow threshold. Correspondingly, the fan is in a low-power operation mode at this time.

[0107] By combining the fan's operating status with the target gas flow rate, the adjustment method for the fan can be accurately determined, thereby improving the accuracy of fan adjustment.

[0108] In some other exemplary embodiments, the firepower level of the stove can be analyzed directly based on the target gas flow rate to obtain the target firepower level corresponding to the target gas flow rate; furthermore, the operating mode of the range hood's upper fan can be adjusted according to the target firepower level.

[0109] In some other exemplary embodiments, the operating status of the fan on the range hood can also be obtained; wherein the operating status may include an on state and an off state.

[0110] Correspondingly, adjusting the operating mode of the range hood according to the target gas flow can include:

[0111] The firepower level of the stove is analyzed based on the target gas volume to obtain the target firepower level corresponding to the target gas flow rate.

[0112] Adjust the operating mode of the blower according to its operating status and the target fire level.

[0113] In one example, when the stove is in the "on" state and the target firepower level is higher than the first preset level, the third target level corresponding to the target firepower level is obtained; furthermore, the fan's operating mode is adjusted to the third target level. The first preset level can be a pre-set firepower level corresponding to when the stove is not turned on. Correspondingly, the fan is in normal power consumption operation mode at this time.

[0114] In another example, the fan is turned off when the operating status is "on" and the target firepower level is equal to or lower than a first preset level. Here, "operating status is on" and "target firepower level is equal to or lower than the first preset level" indicates that the fan is on and the stove is off. Correspondingly, the fan is in a low-power operation mode at this time.

[0115] In another example, when the fan is in an off state and the target firepower level is higher than the first preset level, the fan is adjusted to a preset on state, and the fourth target level corresponding to the target firepower level is obtained; furthermore, the fan's operating mode is adjusted to the fourth target level. Correspondingly, the fan is in normal power consumption operating mode at this time.

[0116] In another example, the fan remains operational when the operating status is off and the target firepower level is equal to or lower than the first preset level. Correspondingly, the fan is in a low-power operation mode at this time.

[0117] In this embodiment, the present application uses a sound wave emitting end, a first receiving end, and a second receiving end installed inside the gas pipe; and obtains the target energy difference between the sound wave energy received by the first receiving end and the sound wave energy received by the second receiving end. Then, based on the target energy difference and the target energy threshold, the target gas flow corresponding to the target energy difference is obtained. The present application can obtain the target gas flow of the stove in real time and accurately by using the sound wave energy difference. Furthermore, the operating mode of the range hood can be adjusted based on the relatively accurate target gas flow of the stove, which can not only improve the accuracy of the linkage between the range hood and the stove, but also improve the real-time linkage between the range hood and the stove.

[0118] like Figure 5 The diagram shown is a flowchart illustrating a method for determining a target energy threshold according to an embodiment of this application; the details are as follows:

[0119] S501, obtain the first relative position between the first receiving end and the sound wave transmitting end, and the second relative position between the second receiving end and the sound wave transmitting end.

[0120] In this embodiment, the first relative position can characterize the relative distance and direction between the first receiving end and the sound wave transmitting end. The second phase position can characterize the relative distance and direction between the second receiving end and the sound wave transmitting end.

[0121] S503, based on the first relative position and the second relative position, perform position information analysis and processing to obtain the associated position information between the first receiving end, the second receiving end and the sound wave transmitting end;

[0122] In the embodiments of this application, the associated positional relationship can characterize the distance between the first receiving end, the second receiving end, and the sound wave emitting end, as well as the angle formed between the first receiving end and the sound wave emitting end, and between the second receiving end and the sound wave emitting end.

[0123] In some exemplary embodiments, a first position of the sound wave emitting end is determined; further, based on the first position, the first phase position, and the second relative position, the positions of the first receiving end and the second receiving end are analyzed to obtain a second position corresponding to the first receiving end and a third position corresponding to the second receiving end; then, based on the first position, the second position, and the third position, associated position information can be analyzed and obtained.

[0124] S505, Based on the correspondence between the preset location and the preset energy threshold, determine the preset energy threshold corresponding to the associated location information;

[0125] In this embodiment of the application, the preset position may refer to the pre-set associated position between the first receiving end, the second receiving end, and the sound wave transmitting end.

[0126] The correspondence between preset locations and preset energy thresholds can be pre-defined and can characterize the relationship between the associated locations and energy thresholds. As an example, the correspondence between preset locations and preset energy thresholds can be a preset correspondence table.

[0127] In some exemplary embodiments, a preset energy threshold corresponding to the associated location information is selected from a preset correspondence table based on the associated location information.

[0128] S507, the preset energy threshold corresponding to the associated location information is determined as the target energy threshold.

[0129] In some exemplary embodiments, when the target energy threshold includes a first energy threshold, a second energy threshold, a third energy threshold, and a fourth energy threshold, the preset energy threshold corresponding to the associated location information also includes the first energy threshold, the second energy threshold, the third energy threshold, and the fourth energy threshold.

[0130] In this embodiment, the present application limits the preset energy threshold by using the associated position information between the first receiving end, the second receiving end, and the sound wave transmitting end. This allows the preset energy threshold to be adjusted accordingly when the associated position information changes, thereby ensuring the accuracy of the correspondence between the target energy difference and the target gas flow threshold and improving the accuracy of the stove-range linkage.
