Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the gas appliance of the embodiment includes a combustion chamber 1 and a smoke collection cage 3. Besides, the gas equipment also comprises a flue gas pipeline which is connected with the combustion chamber 1 and/or the smoke collecting hood 3. Further, the gas equipment further comprises a first detector 5, and the first detector 5 is installed on at least one of the combustion chamber 1, the smoke collecting hood 3 and the flue gas pipeline and used for detecting whether the set gas concentration in the flue gas exceeds the standard or not. For example, when the first detector 5 is installed in the combustion chamber 1, then the first detector 5 functions to detect whether the set gas concentration in the combustion chamber 1 exceeds the standard. When the first detector 5 is installed in the smoke collecting hood 3, the corresponding first detector 5 functions to detect whether the set gas concentration inside the smoke collecting hood 3 exceeds the standard.
Because first detector 5 sets up in gas equipment's inside, and then can detect out the trouble of gas equipment itself fast, avoid appearing the potential safety hazard, guarantee gas equipment's safe in utilization, improve gas equipment's use reliability. The gas equipment can mainly avoid the danger possibly caused by continuous gas leakage due to failure of the middle fan 4, the wind pressure sensor or the wind pressure switch of the gas equipment.
In one embodiment, the gas appliance further comprises a controller 6 and a gas valve. Wherein, the controller 6 is connected with the first detector 5, and the gas valve is connected with the controller 6. When the first detector 5 detects that the gas concentration exceeds the standard, or when the first detector 5 detects that the oxygen or carbon dioxide concentration does not reach the standard, a signal is sent to the controller 6, and the controller 6 controls the gas valve to be closed under the condition.
For example, when the fan 4, the wind pressure sensor or the wind pressure switch in the gas equipment fails to cause continuous leakage of the gas, the concentrations of the components of the flue gas in the combustion chamber 1, the smoke collecting hood 3 and the flue gas pipeline gradually change, wherein the concentration of the gas gradually increases, and the concentration of the oxygen or the carbon dioxide gradually decreases. Furthermore, no matter the first detector 5 is arranged in the combustion chamber 1, the smoke collecting hood 3 or the smoke pipeline, the first detector 5 can detect the change of the concentration of each component of the smoke at the first time, and then a user can conveniently obtain the operation condition of the gas equipment at the first time.
In one embodiment, the gas appliance includes a second detector and an ignition switch. The second detector detects the flame in the combustion chamber 1; and an ignition switch connected with the controller 6. The second detector sends a signal to the controller 6 when it detects that there is no flame in the combustion chamber 1, in which case the controller 6 controls the ignition switch to be closed. It is clear that the precondition for the controller 6 to control the ignition switch to be turned off is: the first detector 5 detects that the gas concentration exceeds the standard, or the first detector 5 detects that the oxygen or carbon dioxide concentration does not reach the standard. In this case, since there is already a leakage of the gas, if the ignition switch performs the ignition operation, a safety hazard may be caused. And the second detector detects that no flame exists in the combustion chamber, which shows that although the gas exceeds the standard at the moment, no urgent danger exists, so that the explosion of the gas under the condition of meeting the flame can be avoided only by controlling the ignition switch to be turned off at the moment. Once the second detector detects that a flame is present, the risk of explosion of the gas appliance cannot be reduced by controlling the ignition switch, and only remedied by other measures.
Specifically, once the gas concentration is detected to exceed the standard (or the concentration of carbon dioxide and oxygen does not reach the standard), and the ignition switch is already operated for ignition, the use safety of the gas equipment is further ensured at the moment, and a fire extinguisher can be arranged in the combustion chamber 1 and is connected with the controller 6. Furthermore, when the second detector detects that there is a flame in the combustion chamber 1, a signal is sent to the controller 6, and the controller 6 controls the fire extinguisher to be turned on and performs a fire extinguishing operation on the combustion chamber 1. Wherein the fire extinguisher may inject inert gas into the combustion chamber 1 to extinguish the flame in the combustion chamber 1. Of course, the fire extinguisher may take other forms to achieve the same fire extinguishing purpose.
In fig. 1, the ignition switch is connected to the pulse igniter 7, and the operation of the pulse igniter 7 is controlled by the ignition switch. The pulse igniter 7 can perform an ignition operation only when the ignition switch is closed.
In one embodiment, the flue gas duct comprises a first duct arranged between the combustion chamber 1 and the fume collecting hood 3, the first duct being located in the heat exchanger 2. Referring to fig. 1, a heat exchanger 2 is disposed between a combustion chamber 1 and a smoke collection cage 3, and a first duct is located inside the heat exchanger 2. Under this kind of condition, gas equipment can carry out abundant utilization to the heat of flue gas, and then avoids the waste of energy.
Further, the flue gas pipeline still includes the second pipeline of connecting combustion chamber 1, and the gas outlet of combustion chamber 1 is connected to the second pipeline. Through the setting of second pipeline, can be convenient for discharge the outside of gas equipment with the flue gas.
Wherein, when the flue gas duct comprises a first duct and a second duct, the first detector 5 may be mounted to the first duct or the second duct. For example, when the first detector 5 is mounted to the second pipe, replacement of the first detector 5 can be facilitated. When the first detector 5 is installed in the first duct, it can detect the change of the gas concentration in the combustion chamber 1 more quickly than the second duct installed in the smoke collecting hood 3, and thus can ensure the reliability of detection; compared with the installation in the combustion chamber 1, the flue gas mixing is more uniform, so that the misdetection can be avoided.
Wherein, first detector 5 can be for detecting whether gas, carbon dioxide or oxygen concentration are located the gas concentration sensor of setting for the interval in the flue gas, and first detector 5 is installed in first pipeline and/or second pipeline.
In one embodiment, the first detector 5 is a gas detection probe mounted to the fume collecting hood 3. For example, as the gas is continuously injected without burning, the oxygen content or the carbon dioxide content is continuously decreased. When the first detector 5 detects that the oxygen or carbon dioxide content is reduced, it can be determined that there is a gas leakage problem in the gas appliance at this time. Of course, the examples herein do not limit the scope of the present invention. The first detector 5 may take any of the configurations disclosed in the prior art, as long as it is capable of measuring the concentration of the component in the flue gas.
In one embodiment, the gas appliance further comprises an alarm. The alarm is connected with the first detector 5, and when the first detector 5 detects that the set gas concentration in the flue gas exceeds the standard, the alarm sends out an alarm signal. Specifically, the first detector 5 detects that the set gas concentration in the flue gas is outside the set interval, and sends a signal to the controller 6, and the controller 6 controls the alarm to send an alarm signal. Once the alarm signal is received, the user can manually carry out corresponding treatment on the gas equipment at the first time so as to ensure the use safety.
In one embodiment, the gas-fired appliance is a wall-hanging stove. It should be noted that the gas appliance may be any household appliance that uses gas as fuel, in addition to the wall-mounted furnace.
In one embodiment, the operation of the gas-fired device is described with reference to FIG. 2. In the absence of a heat demand, the gas appliance is in a standby state. When the gas equipment has a heat demand, the gas equipment carries out self-checking and judges whether gas leakage exists. Wherein, when the gas equipment does not have the condition that the gas leaked, the gas equipment normally opened. And whether the interior of the gas equipment meets the heat requirement is judged based on the opening of the gas equipment, and once the heat requirement is met, the gas equipment enters the standby state again, otherwise, the gas equipment is continuously heated. And when detecting that the gas equipment has gas leakage, cutting off the gas valve, reporting the gas leakage fault by the whole gas equipment, and stopping the operation of the gas equipment. At the moment, the gas equipment is adjusted and repaired by human intervention until the maintenance of the leakage point of the gas equipment is finished, and the gas equipment enters the standby state again.
The above embodiments are merely illustrative, and not restrictive, of the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all of the technical solutions should be covered by the scope of the claims of the present invention.
