as shown in fig. 1, the air supply device 4 may be a blower, and the controller 62 may control the air supply amount of the blower by controlling the rotation speed of the blower, for example, when the air supply amount needs to be increased, the controller 62 may increase the rotation speed of the blower; when the amount of supplied air needs to be reduced, the controller 62 may reduce the rotational speed of the blower; the inner side of the cooker support 5 means a side of the cooker support 5 close to the burner 1 in a radial direction of the burner 1.
As shown in fig. 1 and 4, the gas range further includes a gas sensor 61, the gas sensor 61 is used for acquiring a concentration value (usually measured in parts per million (ppm) by volume) of a target gas component in the gas sampling space 51; a controller 62, the controller 62 being configured to: and controlling the rotating speed of the blower according to the concentration value of the target gas component so that the concentration value of the target gas component is in a preset range.
As shown in fig. 1 and 4, the gas stove provided by the embodiment of the present invention further includes a gas sensor 61 and a controller 62, so that the gas sensor 61 can obtain a concentration value of a target gas component in a gas combustion product of the gas sampling space 51, the controller 62 can determine whether the gas is completely combusted according to the concentration value of the target gas component, and then according to the combustion condition of the gas,the air supply quantity of the air supply device 4 is controlled to adjust the air quantity entering the combustor 1, so that the concentration value of the target gas component is in a preset range, the mixing ratio of the fuel gas and the air is controlled, and the ratio of the air and the fuel gas can completely meet or more approach the equation: CH (CH)4+2O2＝2H2O+CO2+ Q (heat) of said CH4And O2The proportion of (2) ensures the complete combustion of the gas, and further improves the combustion stability of the gas and the heat efficiency of the gas combustion.
In the above embodiment, the target gas component may be carbon monoxide (CO), sulfur oxide (SOx), nitrogen oxide (NOx), methane (CH)4) One of them may be a combination of plural kinds of carbon monoxide, sulfur oxide, nitrogen oxide and methane. When the target gas component may be one of carbon monoxide, sulfur oxide, nitrogen oxide, and methane, the gas sensor 61 detects a gas component, which facilitates the installation and detection of the gas sensor 61.
The following description will be made of the control process of the controller 62 taking the target gas component as carbon monoxide (CO) as an example: when the concentration value of carbon monoxide acquired by the gas sensor 61 exceeds the upper limit value of the preset range, which indicates that the gas is incompletely combusted in the combustor 1, the controller 62 controls the air supply device 4 to increase the air supply amount to ensure that the air and the gas are fully mixed, so that the gas can be completely combusted in the combustor 1, and the concentration value of carbon monoxide is ensured to be within the preset range.
The gas sensor 61 may be a solid-state gas sensor, such as a high gap ion semiconductor Metal Oxide (MOX) gas sensor.
In the gas range described above, the gas sensor 61 is not disposed at a unique position, and for example, the gas sensor 61 may be disposed at the following positions: as shown in fig. 1 and 2, the gas range further includes: an air extraction device 71 (such as a fan); an induced air pipeline 72, wherein a first end of the induced air pipeline 72 is communicated with the air extractor 71, and a second end a extends into the gas sampling space 51; the gas sensor 61 is provided on the induced air duct 72. When the burner 1 is in operation, the gas extraction device 71 is activated, the gas extraction device 71 extracts the gas in the gas sampling space 51 into the induced air pipeline 72, and the gas sensor 61 arranged on the induced air pipeline 72 can acquire the concentration value of the target gas component. The gas sensor 61 may be provided directly in the gas sampling space 51. Compared with the gas sensor 61 directly arranged in the gas sampling space 51, the gas sensor 61 is arranged on the induced air pipeline 72, so that the gas sensor 61 is prevented from being damaged due to the fact that the gas sensor is too close to flame during gas combustion, and the space of the position of the combustor 1 is prevented from being excessively occupied, and the structure of the combustor 1 is more compact.
In order to enable the controller 62 to accurately control the amount of air blown by the blower to ensure complete combustion of the gas, as shown in fig. 1 and 2, the top of the cooker support 5 forms a support surface 52 for supporting the cooker 100, and the second end a of the air introduction duct 72 extends into the gas sampling space 51 between the support surface 52 and the burner 1 in the vertical direction. When the burner 1 burns, most of combustion products of gas are concentrated in the gas sampling space 51 between the burner 1 and the supporting surface 52 of the cooker support 5, and the second end a of the air guiding pipeline 72 extends into the gas sampling space 51 between the supporting surface 52 of the cooker support 5 and the burner 1, so that the concentration of target gas components pumped into the air guiding pipeline 72 by the air extractor 71 is closer to the actual concentration of the target gas components in the combustion products of the gas, and thus, the concentration value of the target gas components acquired by the sensor can be more accurate, and the controller 62 can accurately control the air supply amount of the blower to ensure the complete combustion of the gas.
As shown in fig. 1 and 3, the burner 1 includes an inner burner 11 and an outer burner 12 located outside the inner burner 11, the outer burner 12 is annular, and the gas pipeline 2 is communicated with both the inner burner 11 and the outer burner 12.
In order to enable the controller 62 to control the air blowing amount of the blower more accurately to ensure complete combustion of the gas, as shown in fig. 1 and 3, the second end a of the air inducing pipeline 72 passes through between the inner furnace head 11 and the outer furnace head 12 and extends into the gas sampling space 51 between the supporting surface 52 of the cooker support 5 and the burner 1. When the burner 1 works, a subspace can be formed by the flame sprayed by the inner burner 11, the flame sprayed by the outer burner 12 and the bottom of the cooker 100 (such as a pot), products after gas combustion can be easily gathered in the subspace, and the second end a of the air-inducing pipeline 72 penetrates out from the space between the inner burner 11 and the outer burner 12, so that the second end a of the air-inducing pipeline 72 can extend into the subspace of the gas sampling space 51, and the concentration of the target gas component pumped into the air-inducing pipeline 72 by the air extractor 71 is closer to the actual concentration of the target gas component in the combustion products of the gas, so that the concentration value of the target gas component obtained by the sensor can be more accurate, and the blower controller 62 can more accurately control the air supply amount to ensure the complete combustion of the gas.
In order to sufficiently mix the air sent by the air supply device 4 and the gas, as shown in fig. 1, the gas stove further includes an ejector 81, the gas pipeline 2 is communicated with the burner 1 through the ejector 81, and the air supply device 4 is communicated with the ejector 81 through a connecting pipeline 82. Compare in direct air supply arrangement 4 and combustor 1 intercommunication, through being linked together air supply arrangement 4 and ejector 81, the air that air supply arrangement 4 sent out just can mix back reentrant combustor 1 burning with the gas in ejector 81 like this, can guarantee the gas more even with the air mixing when getting into combustor 1 to guarantee that the gas fully burns in combustor 1.
In the use process of the gas stove, if the burner 1 is accidentally extinguished, if the gas pipeline 2 supplies gas to the burner 1 all the time, a part of the gas enters the air, which is not beneficial to the safety of users. To address this issue, as shown in fig. 1 and 4, the controller 62 is configured to: during the operation of the burner 1, the gas valve 3 is controlled to close if the variation in the concentration value of the target gas component exceeds a preset value. Through the arrangement, if the burner 1 is accidentally extinguished, the combustion of the gas is stopped, the concentration of the target gas component will change obviously, for example, the content of carbon monoxide (CO) will decrease, and at this time, if the variation of the concentration value of the target gas component exceeds the preset value, the controller 62 can control the gas valve 3 to close to stop supplying the gas to the burner 1, so as to prevent excessive gas from entering the air around the gas stove, and thus, the use safety of a user can be guaranteed.
When the user uses the gas range, the user often needs to remove the cooker 100 from the cooker support 5, for example, after cooking, the user needs to take the pot away from the cooker support 5, and if the gas valve 3 is not closed, the burner 1 will be empty, and the user needs to manually cut off the gas supply, which adds one step of operation and brings great trouble to the user. To address this issue, as shown in fig. 1 and 4, the controller 62 is configured to: during the operation of the burner 1, the gas valve 3 is controlled to close if the variation in the concentration value of the target gas component exceeds a preset value. With this arrangement, if the user removes the cooker 100 from the cooker support 5, the upper side of the gas sampling space 51 is opened and a significant change in a target gas component (e.g., carbon monoxide) occurs, and if a change in the concentration value of the target gas component exceeds a preset value, the controller 62 controls the gas valve 3 to be closed to stop the supply of gas to the burner 1 to prevent the burner 1 from being empty, so that the user does not need to manually cut off the supply of gas at this time, thereby greatly facilitating the use of the user.
When the air supply device 4 is a blower, as shown in fig. 4, the controller 62 includes a central controller 621, a pulser 622, and a blower controller 623, the pulser 622 is connected to the gas valve 3, the blower controller 623 is connected to the blower, the central controller 621 can control the opening and closing of the gas valve 3 through the pulser 622, and the central controller 621 can control the rotation speed of the blower through the blower controller 623 to adjust the air supply amount.
The central controller 621, the pulser 622, and the fan controller 623 may be integrated together or may be separately disposed, and are not limited herein.
As shown in fig. 3, the burner 1 is further provided with an ignition magnet needle 91, and the ignition magnet needle 91 can ignite the gas injected from the burner 1 when the gas valve 3 is opened.
As shown in fig. 3 and 4, the combustor 1 is further provided with a thermocouple 92, the thermocouple 92 is connected to the controller 62, the thermocouple 92 can acquire a temperature value of the combustor 1, the controller 62 can determine a combustion condition of the combustor 1 according to the temperature value fed back by the thermocouple 92, for example, when the combustor 1 is accidentally extinguished, the temperature of the combustor 1 will decrease, and when the temperature value acquired by the thermocouple 92 is less than a threshold value, the controller 62 can close the gas valve 3 to prevent excess gas from entering the air, which is beneficial to improving safety. The thermocouple 92 can be matched with the gas sensor 61 for mutual backup, and the controller 62 can judge the combustion condition of the burner 1 according to the data fed back by the thermocouple 92 and the gas sensor 61, so that the gas stove is safer to use.
In the gas range, the number of the burners 1 may be one or two (as shown in fig. 2), and is not limited herein. When the number of the burners 1 is two, the two burners 1 may be provided with the air supply device 4 and the gas sensor 61, or one of the burners 1 may be provided with the air supply device 4 and the gas sensor 61 (as shown in fig. 2), which is not limited in detail herein.
