[0032] 【第一实施例】 [0032] [First Embodiment]

[0033] 请参阅图1及图2,其为本发明的具有火焰检测功能的瓦斯炉的第一实施例的示意图。 [0033] Please refer to FIGS. 1 and 2, a first embodiment of a gas stove having a flame detection thereof of the present invention. FIG. 如图所示,具有火焰检测功能的瓦斯炉1包含:一开关模块1〇、一火焰检测模块2〇及一处理模块30。 As shown, the stove having a flame detection function comprising: a switch module 1〇, a fire detection module and a processing module 30 2〇. 开关模块10可以包含设置于瓦斯炉外部的旋钮、电子点火器等。 The switch module 10 may comprise a knob disposed outside a gas stove, the electronic ignition and the like. 火焰检测模块20 包含至少一可见光检测单元21,其可以检测450nm〜500nm以及600nm〜780nm波长的辐射光波。 Flame detecting module 20 includes at least a visible light detecting means 21, which can detect radiation and the optical wave 450nm~500nm 600nm~780nm wavelength. 具体地说,火焰检测模块20的可见光检测单元21可以检测蓝色系(450nm〜500nm波长) 以及红黄色系(600nm〜780nm波长)的火焰。 Specifically, the flame detector module 21 of the visible light detection unit 20 can detect a blue (450nm~500nm wavelength) and red and yellow color (600nm~780nm wavelength) flame.

[0034] 当使用者操作开关模块10的旋钮以开启瓦斯炉时,电子点火器进行电子点火,且同时传送一点燃信号101至处理模块30;处理模块30接收该点燃信号101后,启动火焰检测模块20,以使可见光检测单元21对瓦斯炉火焰的辐射光波进行检测。 [0034] When the user operates the switch knob 10 to turn on gas stove module, electronic ignition for electronic ignition, and simultaneously transmits an ignition signal 101 to the processing module 30; 30 receiving the ignition signal processing module 101, to start the flame detector module 20, so that the visible light wave radiation detection unit 21 detects the flame gas burners. 可见光检测单元21检测到450nm〜500nm波长的辐射光波时,则传送第一光波信号211至处理模块30,而当可见光检测单元21检测到600nm〜780nm波长的福射光波,则传送第二光波信号212至处理模块30。 When the detection unit 21 detects the visible radiation wavelength lightwave 450nm~500nm, a first lightwave signal 211 is transmitted to the processing module 30, and when the visible light detection unit 21 detects the emitted light waves 600nm~780nm Four wavelength, the second light wave signal transmission 212 to the processing module 30. 处理模块30若同时接收该第一光波信号211及第二光波信号212,或是只接收到第二光波信号212时,处理模块30据以控制开启抽风装置40进行抽风作业,且同时可以控制警示装置50 的至少一扬声单元及至少一发光单元发出警示。 When the processing module 30 while receiving the first signal 211 and the second light wave lightwave signal 212, or only to the second wave receiving signal 212, the data processing module 30 to control the ventilation opening of ventilation device 40 operation, and while controlling the warning at least one device 50 speaker units and at least one light emitting unit alert. 换言之,处理模块30只要有接收到第二光波信号212,则控制开启抽风装置40及警示装置50。 In other words, as long as the processing module 30 receives the signal 212 to the second wave, the control means 40 ventilation opening 50 and the warning device.

[0035] 具体地说,瓦斯炉在正常的使用状态下,瓦斯应完全燃烧,而使瓦斯炉火焰呈现蓝色(辐射光波的波长约为450nm〜500nm),而当瓦斯炉火焰呈现红黄色(辐射光波的波长约为600nm〜780nm)时,表示瓦斯燃烧不完全,此时会产生一氧化碳,若使用者无实时处理该状况,恐有一氧化碳中毒的危险。 [0035] Specifically, a gas stove in a normal use state, the gas should be complete combustion, the stove flame blue color (a wavelength of light wave radiation of about 450nm~500nm), red and yellow when rendered flame gas burners ( light wave radiation wavelength of about 600nm~780nm), it indicates gas incomplete combustion, carbon monoxide is generated at this time, if the user no real-time processing of the situation, fear of danger of carbon monoxide poisoning. 本实施例利用可见光检测单元21,以检测当使用者开启瓦斯炉后,瓦斯炉火焰的颜色(即检测450nm〜500nm及600nm〜780nm波长的辐射光波);若当瓦斯炉火焰只呈现蓝色(处理模块30只接收到第一光波信号211)时,表示瓦斯炉火焰燃烧完全,为正常使用状态,因此处理模块30不控制启动抽风装置40或是警示装置50;而当瓦斯炉火焰呈现红黄色(处理模块30只接收到第二光波信号212)或是同时呈现有红黄色及蓝色(处理模块30同时接收到第一光波信号211及第二光波信号212)时,表示瓦斯炉火焰燃烧不完全,而有产生一氧化碳的疑虑,因此处理模块30则据以控制启动抽风装置40及警示装置50,以实时抽取一氧化碳,且实时通过警示装置50发出警示声响或是灯光,以提醒使用者。 This embodiment utilizes the visible light detection unit 21 to detect when the user opens a gas stove, the stove flame color (i.e. 450nm~500nm detecting the optical wave and the radiation wavelength 600nm~780nm); if the flame when the gas stove only a blue color ( the processing module 30 receives a first lightwave signal 211), indicates complete combustion flame stove, a normal use state, thus starting the processing module 30 does not control the ventilation means 40 or the warning device 50; reddish yellow when rendered flame gas stove (the processing module 30 receives the signal 212 to the second wave), or when the blue and red and yellow (processing module 30 simultaneously receives the first signal 211 and the second light wave lightwave signal 212) presented simultaneously, represents a combustion gas stove flames completely, while carbon monoxide of doubt, therefore, according to the processing module 30 to control the ventilation means 40 and starting the warning device 50, the extraction of carbon monoxide in real time, and in real time by the warning device emits a warning sound or light 50, to remind the user. [0036] 简单地说,本发明利用可见光检测单元21以检测瓦斯炉火焰的燃烧状态,并依据其燃烧状态(燃烧完全及燃烧不完全),实时地控制启动抽风装置40及警示装置50,藉以可实时地抽取瓦斯炉火焰燃烧不完全时所产生的一氧化碳,且同时可实时警示通知使用者, 藉以可以有效地防止一氧化碳中毒的问题。 [0036] Briefly, the present invention utilizes a visible light detecting means 21 to detect the state of combustion flame gas burners, and according to the combustion state (combustion complete combustion and incomplete), real-time control of a promoter and a warning device 40 exhaust means 50, whereby gas stove can be extracted in real time when incomplete combustion of carbon monoxide generated, while real-time alerts notify the user, thereby effectively preventing the problem of carbon monoxide poisoning.

[0037] 在实际应用中,瓦斯炉火焰呈现红黄色的因素可能有下列几种,其一为瓦斯炉的进风调节有问题;其二为食物于烹煮中,汤汁溢出;其三为瓦斯供应不良。 [0037] In practical applications, a gas stove flame showing red and yellow are the following factors may, one for gas stove air intake regulation in question; the other for food in the cooking, the soup overflow; Third is gas supply is bad. 因此,处理模块30 在实际运作中,当有接收到第二光波信号212,而开启抽风装置40时,可以是先控制调节瓦斯炉风门,并持续通过可见光检测单元21进行火焰检测;若经调整瓦斯炉风门后,处理模块30于一限定时间内,并无再接收到第二光波信号212,则处理模块30不使警示装置50发出警 Accordingly, the processing module 30 in the actual operation, when there is received a second lightwave signal 212, and the ventilation opening means 40 may be adjusted to control the gas stove damper, and continues through the visible light detection means detects the flame 21; if adjusted after the stove damper, the processing module 30 in a limited time, no longer receive a second lightwave signal 212, the processing module 30 not to sound an alarm warning device 50

[0038] 若经调整瓦斯炉风门后,处理模块30仍有接收到第二光波信号212,处理模块30可以是通过装设于瓦斯供气线路的流量计,以检测瓦斯供气是否良好,若瓦斯供气良好,则可能是发生汤汁洒落的问题,处理模块30则可以控制警示装置50发出相对应的警示灯号或是警示声响(例如是音乐或是语音),且还可以同时关闭瓦斯炉的瓦斯供气阀,以避免汤汁持续撒落而使瓦斯炉火焰熄灭后,瓦斯仍持续供出的问题;而若瓦斯供气不良,处理模块30则可以关闭瓦斯炉的瓦斯供气阀,并于一段时间后关闭抽风装置40,且同时发出相对应的警示灯号或是警示声响,以提醒使用者瓦斯供应不良。 [0038] If the adjusted gas stove damper still processing module 30 receives the second lightwave signal 212, the processing module 30 may be mounted to the gas by the gas supply line flow meter to detect the gas supply is good, if good gas supply, there may be a problem soup spills occur, the processing module 30 may control the warning device 50 issues a corresponding warning light or a warning sound (e.g., music or voice) and may also simultaneously closed gas furnace gas supply valve, in order to avoid the problem of scattered soup sustained flame to extinguish gas burners, gas continues to give out; the gas supply if the gas is bad, the processing module 30 may turn off the stove supply valve, and a period of time after closing the ventilation means 40, and while corresponding to the issued warning light or a warning sound to alert the user to supply gas poor. 其中,上述警示装置50可以是依据警示时间的增长,而使其警示声音越来越大,或是灯号闪烁的频率越来越快;且警示装置50还可以是具有一停止钮,使用者可以触压该停止钮以使警示装置50停止,而若警示装置50持续警示一段时间后,停止钮仍未被触压,处理模块30则可以据以关闭瓦斯供气阀。 Wherein the warning device 50 may be a warning based on the growth time, and it is growing alarm sound or flashing lights faster frequency; and the warning device 50 may also be provided with a stop button, a user the stop button can be pressed to contact so that the warning means 50 is stopped, and the warning device 50 when the warning period of time duration, yet stop button is depressed, the processing module 30 may, according to the gas supply valve to close.

[0039]简单地说,当处理模块30有接收到第二光波信号212时,其可以是先控制开启抽风装置40,同时调节瓦斯炉风门且检测瓦斯供气流量,以决定是否控制警示装置50发出警示, 并决定警示装置50所发出的警示灯号或是警示声响。 [0039] Briefly, when the processing module 30 to the second wave signal with a receiver 212, which may be a means to control the ventilation opening 40, while adjusting the gas stove flap and the charge flow detection, to determine whether the warning control means 50 alert, and warning light or a warning sound decided warning device 50 emitted.
