When the faucet is twisted, the water flows through the water tray 3a, and the venturi provided in the water tray 2a is used to generate the pressure friend', thereby opening the gas valve plug and touching the ignition plug 4a, and the gas flows in and starts the differential pressure plate 2a. The gas valve has a pressure disc 2 a 嘱俦, a female fire gas outlet 2 1 a and a main fire gas outlet 2 2 a, and the female fire gas conduit 6 a is in a curved state with two ends respectively. No nozzle 5 a and the mother fire gas outlet 2 1 a, the gas is, the mother fire gas conduit 6 a is introduced into the nozzle 5 a, the nozzle 5 a is corresponding to the ignition plug 4 a, the ignition plug 4 a generated spark ignited while spraying a gas of 5 a, so as to complete the mother fire ignition action of the conventional water heater 1 a. The conventional water heater 1 a is provided with a feedback unit (not shown) for detecting the mother fire. After the mother fire is ignited, the starting gas is started by the main fire gas outlet 5 1263023 2 2 a to guide the burner group 7 a, and ignite The main fire is to supply drowning. As is well known, these conventional water heaters, "the supply of oxygen", when anoxic conditions occur, will cause all of the burners in group = 7 a to be out of flame, resulting in a full Fire, (4), Ruowa (4) continued supply, will occur in the risk. As for the occurrence of oxygen deficiency, part of the reason is because the water will be installed indoors, and it is easy to close all doors, windows = households in order to prevent cold Because the water heater is deficient in oxygen, the gas is outside the heart: this, Hai, and other conventional water heaters 1 a will add a flame detection (8 a, can be seen with reference to the second figure), so that the flame detector needle can enter 2 Above a burner in the burner group 7 a (7 two with the second picture of Cang Jiandi), by means of the furnace ice that can detect the flame (no fire: there is no fire) and stop the tile at the right time: to safety Sexual requirements. μ ' & standard, because the far-end flame detector is only located above the specific burner of the burner group 7 :: and will cause the flame to extinguish because of the lack of oxygen, others such as the damper Caused by a closed size error = partial off-fire condition, or because of strong winds hitting local Burning ^ and so on, will cause the local burner to stall (temporarily extinguished the 邛 熄 熄 处 又 又 又 又 又 又 又 又 又 又 又 又 又 又 又 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 虽 = = The combustion state is re-ignited, but in the first moment, it will be misjudged as "the whole because of the detection of the flame detection:", the burner group 7 a is turned off, and then; the gas supply is not obvious, and every time The user is in a big wind: Hey, he can't continue to get hot water. Every time he has to wait for a period of 1263023 to get normal gas supply improvement. If there is something wrong with it, please refer to the fire condition. In many cases 1 a ignited flame 7 notch 7 4 a, the flame detector map does not burn a certain burner 7 1 a, each burner 7 a of the water heater 1 a will form a split shape with The probe 8 1 a of the center a is again at the center line ... directly above the == 713, so the beam f is again misjudged because the probe 8 1 3 is located at the center ^ 3 of the flame 7 3 a For the entire burner group 7 a I, the situation of the fire, indeed one has Yang Wei, the inventor of this case feels that the above-mentioned prior art is easy to misunderstand people; he still needs to be improved, but is concentrating on research, potential &, # [invention content] [invention purpose] The purpose of the water heater for detecting anoxic state and its detection method is to avoid false positives and correctly determine the true state of hypoxia, so that an effective safety material can be surely targeted for anoxic conditions. In the case of a temporary flameout that is not truly hypoxic, in this case, the gas supply is not stopped, so that the complete improvement of the knowledge is as simple as a paranoid detection: the supply of gas is interrupted by a bonfire. Another purpose of the state detection function water heater and its detection method is to effectively reduce the position of the flame detector to the position of the center of the flame, thereby further reducing the probability of misjudgment by 1263023 steps. . [Features of the Invention] η In the above (4), the present invention provides a water heater having an oxygen-deficient state: t function, which is provided with a gas supply port, and the water heater includes: a burner group; Connected to the gas supply port and the combustion-fire detector, the detection portion of the burner is extended to the burner group, and the flame detector detects whether the burner group has a flameout and a control device is connected The gas control valve and the flame check:: the control device controls the gas control valve to be closed when the number of times of no fire is detected to be greater than or equal to 2 within a predetermined time. The invention further provides a method for detecting oxygen deficiency of a water heater, comprising: a paper "knife-knife method, the water heater starts to burn and starts _timed boundary, and judges that the timer is equal to a predetermined number of times for a predetermined time; and", Λ - Number of people 疋 If the number of non-fires is greater than or equal to the predetermined number of times does not message and stop the gas supply. In order to further understand the present invention, please refer to the following detailed (4) content related to the present invention. Please provide a number of waters having a function of detecting hypoxia: The detection method is mainly based on the improvement of the conventional knowledge, whether it is part of the flameout or the bonfire of the whole burner group will stop: the lack of mistakes and the progress of the flame detector is required; (4) The central government lacks %, and the 俾 进 — — 降低 降低 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = In addition to the supply of gas to the gas supply port 1 2, and: 11, a gas control room 13, - flame detection cries 1 4, a control device 丄 5, a mouth 7, and - an alarm 18 and the like. 16, - Counter 1 The burner group 1 1, contains most of the gas supply to the burner group i ] ... 2 丄 1, 1, after a burner is ignited: the combustion mode, all the burners!

[Features and Advantages] In the embodiment of the present invention as described above, since the false positive can be surely avoided and the true hypoxic state can be correctly judged, the device is stopped. Tile, supply, and warning messages to ensure effective safety against hypoxia To avoid a dangerous situation, the various types of temporary flameouts that are not really in anoxic state can be re-ignited by the bypass of adjacent burners. Therefore, it is not necessary to stop = watt = supply, and use After the embodiment of the present invention, it is possible to surely cut off the positive oxygen-deficient state. For the temporary flame-out situation in which the various types are not truly anoxic, the gas supply is not stopped, so that it is not only because of the temporary flameout. Let the operation of the water heater stop, it is indeed possible to improve the knowledge, such as paranoia, the lack of detection: a bonfire is the supply of gas, and after the gas is interrupted, it must wait for a period of supply of gas. , Shang Erchen, the soil, water state and detection method provided by the invention with the hypoxic state detecting the function of the moon, can solve the previous one: knowing the missing 'belongs-- having high industrial utilization value= Buckle, with the effect of the improvement, in line with the daily transformation of the requirements of the 阜利法提 a cap, respect for the review and grant the rights of the inventor.
