The gas heating water heater comprises a burner and a flame detection system. The flame detection system includes at least two flame detection devices. The at least two flame detection devices are used for detecting flame combustion conditions at different positions of the burner. According to the flame detection system of the gas heating water heater, the flame combustion conditions of different positions of the burner are detected by arranging the at least two flame detection devices, so that judgment can be performed based on the detection results of the at least two flame detection devices when the flame combustion conditions of the burner are judged. Meanwhile, the arrangement of at least two flame detection devices can also avoid the situation that the flame detection system cannot normally detect flame due to the fact that the flame detection devices fail or fail when only one flame detection device exists.
The control method of the gas heating water heater provided by the embodiment of the application comprises the following steps of:
obtaining detection results of at least two flame detection devices;
and controlling the gas heating water heater according to the detection results of the at least two flame detection devices.
According to the control method of the gas heating water heater, when the gas heating water heater is controlled, the control is performed according to the detection results of the at least two flame detection devices, so that frequent shutdown caused by unstable combustion of the burner can be avoided, and the fault judgment accuracy of the flame detection system is improved.
The structure of the gas heating water heater and the control method thereof according to the embodiment of the present application will be described in detail with reference to fig. 1 and 2.
As shown in fig. 1, the gas heating water heater according to the embodiment of the present application includes a burner 1 and a flame detection system. The flame detection system comprises a first flame detection means 3 and a second flame detection means 2 arranged on the burner 1. The first flame detection device 3 and the second flame detection device 2 are respectively arranged at different positions on the burner 1, so that the flame combustion condition at different positions of the burner 1 can be detected. For example, when the flame combustion of the burner 1 is unstable, the flame combustion conditions at different positions of the burner 1 are different, and the first flame detection device 3 may not detect the flame, but the second flame detection device 2 may detect the flame, and at this time, it is not necessary to immediately control the gas heating water heater to stop. The flame detection system in the prior art has only one flame detection device, when the flame detection device does not detect flame, the control system can immediately control the gas heating water heater to stop, and the flame at other positions of the burner is in a normal burning state, but the flame detection device is temporarily not in the position due to unstable burning, so that the stop operation at the moment belongs to erroneous judgment. In summary, the flame detection system of the embodiment can perform secondary judgment on the combustion condition of the flame of the burner by arranging two flame detection devices, so that the fault judgment accuracy of the flame detection system is improved.
In an embodiment not shown in the drawings, more than two flame detection means may also be provided to more accurately detect the flame combustion condition of the burner. Of course, when two or more flame detection devices are provided, problems such as manufacturing cost and assembly space are considered. The flame detection system shown in this embodiment includes two flame detection devices that were developed by the designer through comprehensive analysis and consideration.
In order to more accurately detect the flame combustion condition of the burner, both flame detection devices in the present embodiment are directly provided on the burner 1.
In an embodiment not shown in the drawings, the flame detection device may be disposed at other positions of the gas heating water heater as long as the combustion condition of the flame can be detected, for example, the flame detection device may be disposed on a housing of the gas heating water heater as long as the position of the sensing portion for detecting the flame is disposed corresponding to the position of the burner to be detected.
In particular, in the present embodiment, the first flame detection device 3 is used for detecting the flame combustion condition of the end portion of the burner. The second flame detection device 2 is used for detecting the flame combustion condition of the middle part of the burner. In general, the middle part of the burner 1 is more stable in flame combustion, while the end parts of the burner 1 are less stable in flame combustion. The present embodiment is therefore provided with a flame detection means in the middle and end portions, respectively, to more accurately determine the flame combustion condition of the burner, for example, when the first flame detection means 3 does not detect a flame, control is continued based on the detection result of the second flame detection means 2. If the second flame detection means 2 does not detect a flame either, the gas heating water heater can be immediately controlled to stop. However, if the second flame detection device 2 detects the flame at this time, the normal operation of the gas heating water heater can be controlled continuously, after the combustion of the burner is stable, the detection result of the first flame detection device 3 is acquired again, if the first flame detection device 3 detects the flame at this time, the normal operation of the gas heating water heater is controlled, and if the first flame detection device 3 still does not detect the flame at this time, the gas heating water heater is controlled to stop.
Preferably, the gas heating water heater of the present embodiment further includes an ignition device 4. At least one of the at least two flame detection means is adapted to detect a flame combustion situation at an ignition position of the burner close to the ignition means 4. Since the flame combustion condition at the ignition position of the ignition device 4 is generally stable, the provision of at least one flame detection device at the ignition position of the ignition device 4 can reduce the probability of erroneous judgment of a failure.
Preferably, the gas heating water heater further comprises a control system which is coupled with the flame detection system, and the control system controls the gas heating water heater according to the detection result of the flame detection system.
In order to enable a user to timely acquire the working condition of the gas heating water heater, the gas heating water heater of the embodiment further comprises an alarm device. When at least some or all of the flame detection devices do not detect flame, the control system controls the alarm device to send an alarm signal. After receiving the alarm signal, the user can check the related components of the gas heating water heater to ensure that the gas heating water heater is in a good working state.
As shown in fig. 1, the gas heating water heater of the present embodiment further includes a fan 13 and a wind pressure switch 14.
In order to make the gas supply of the burner adjustable, the gas heating water heater of the present embodiment further includes a gas proportional valve 9 provided between the gas inlet 10 and the burner 1.
The gas heating water heater of this embodiment can provide both heating hot water and domestic water. As shown in fig. 1, the heating water outlet 6 is used for outputting heating hot water. And the heating hot water is returned to the upper side of the burner 1 through the heating return pipe 5 to form a cycle. And the domestic water outlet 7 is used for outputting heated domestic water, the domestic water inlet 11 is used for inputting unheated domestic water, and the unheated domestic water exchanges heat with heating hot water heated by the burner 1 in the plate heat exchanger 8 to form heated domestic water and is output through the domestic water outlet 7.
The gas heating water heater of the present embodiment further includes a water pump 12. The water pump 12 pumps the exothermic heating water back to the heating return water pipe 5 to continue heating to form a heating cycle.
When the gas heating water heater of this embodiment is started, the fan 13 is started first, and when the wind pressure switch 14 detects that the fan 13 is started, a signal is fed back to the control system. The control system controls the ignition device 4 to ignite, and the fuel gas proportional valve 9 is opened to start delivering fuel gas. After successful ignition, the flame spreads over the upper surface of the burner 1, igniting the other fire rows. The flame detection device is used for detecting whether ignition is successful or not, and the gas proportional valve 9 continuously conveys gas under the condition that ignition is unsuccessful, so that potential safety hazards are caused.
The following describes the control method of the gas heating water heater of this embodiment in detail:
the control method of the gas heating water heater provided by the embodiment of the application comprises the following steps of:
obtaining detection results of at least two flame detection devices;
and controlling the gas heating water heater according to the detection results of the at least two flame detection devices.
According to the control method of the gas heating water heater, when the gas heating water heater is controlled, the control is performed according to the detection results of the at least two flame detection devices, so that frequent shutdown caused by unstable combustion of the burner can be avoided, and the fault judgment accuracy of the flame detection system is improved.
In this embodiment, if the first flame detection device 3 detects a flame, the gas heating water heater is controlled to operate normally. If the first flame detection device 3 does not detect flame, the gas heating water heater is controlled according to the detection result of the second flame detection device 2.
As shown in fig. 2, when the burner combustion is unstable, the detection result of the first flame detection device 3 is first acquired. If the first flame detection device 3 detects flame, controlling the gas heating water heater to normally operate; if the first flame detection device 3 does not detect a flame, the detection result of the second flame detection device 2 is continuously acquired.
If the second flame detection device 2 detects flame, controlling the gas heating water heater to normally operate; if the second flame detection device 2 does not detect flame, the gas heating water heater is controlled to stop.
Because the flame at the end of the burner will first flameout when the combustion is unstable, the control method of the embodiment firstly obtains the detection result of the first flame detection device at the end of the burner when the combustion is unstable, and can control the normal operation when the first flame detection device detects the flame. Of course, the control method is only a preferred embodiment, and is not limited thereto, and the detection result of the second flame detection device may be obtained first.
In order to ensure safe operation of the gas heating water heater, the control method of the embodiment comprises the following steps: if the second flame detection device detects flame in the first set time period, controlling the normal operation of the gas heating water heater; if the second flame detection device does not detect flame within the first set time period, the gas heating water heater is controlled to stop. The control method of the embodiment is more reliable by judging whether the second flame detection device can detect the flame in a set period of time.
Preferably, in order to further improve the reliability and accuracy of the control method of the present embodiment, the control method of the present embodiment needs to acquire the detection result of the first flame detection device again after acquiring the detection result of the second flame detection device.
Specifically, the control method of the present embodiment further includes: if the second flame detection device detects flame, controlling the normal operation of the gas heating water heater, and obtaining the detection result of the first flame detection device after a second set time period, if the first flame detection device detects flame, controlling the normal operation of the gas heating water heater, and if the first flame detection device does not detect flame, controlling the shutdown of the gas heating water heater. The arrangement avoids the accident caused by the fact that the gas heating water heater continues to operate under the condition that the burner only burns locally. For example, when the middle of the burner has been flame-fired, the end has not been flame-fired. When the first flame detection device 3 does not detect the flame, the second flame detection device 2 detects the flame, and then the gas heating water heater is controlled to normally operate. If no further decision is made, there may be a case where the end of the burner has not been flame, at which time there is a risk of sustained release of gas resulting in an accident. And further judgment is carried out, and the detection result of the first flame detection device 3 is continuously acquired: when the first flame detection device 3 detects flame, normal operation is continued, and when the first flame detection device 3 still does not detect flame, the heating water heater is controlled to stop.
In order to make the further determination of the control method of the present embodiment more accurate to avoid the detection error caused by unstable combustion, the control method of the present embodiment needs to acquire the detection result of the first flame detection device 3 again after the second set period of time. After the second set period, the burner is already in a stable combustion state, so that the detection result of the first flame detection means 3 is more reliable at this time. In particular, in practical applications, the length of the second set period may be set according to practical situations.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same; while the application has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present application or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the application, it is intended to cover the scope of the application as claimed.
