M340421 八、新型說明： 【新型所屬之技術領域】 本創作係關於一種燃氣器具，尤指一種操作方便，而 且可以控制火候的燃氣器具。 【先前技術】 市售的燃氣器具，例如燃氣爐、烤肉爐一般採用壓電 式自動點火裝置。壓電式自動點火裝置就是利用壓電現象 來產生火花，將該火花的能量作點著燃氣之用。所謂壓電 就是對壓電元件給予壓力或拉張應力就會產生電氣，用此 方法產生的電氣稱為壓電現象。 壓電式點火裝置的動作是先旋轉考克旋鈕而裝在與 考克同一軸上的突起件即抬起擊槌，同時在慢慢開啟考克 動作中燃氣就從喷嘴流出，再進行旋轉旋鈕被抬高擊槌的 突出件即會脫開，擊槌則由於彈簧的復原力向封有壓電元 件的金屬外殼作撞擊動作。壓電元件即產生高電壓而經由 導電線將此高壓電導至點火電極使其產生火花，此時電極 周圍已經由喷嘴流出的燃氣充滿已達到著火範圍的混合 氣體，如此即點著燃氣。 因為壓電式點火裝置必須用人手轉動考克旋鈕才能 點火，所以燃氣器具在操作上不是很方便。 另一方面，在燃氣器具使用的過程中，從燃氣的供應 到將燃氣轉換為熱能後，其中大部分屬於燃氣的控制與調 節。上述考克雖然具有調節燃氣流量的作用，不過由於是 用手轉動考克旋鈕，所以很難精確地產生節流作用。這個 5 M340421 事實對於燒煮食物用的爐具來說原則上沒有太大的影 響，但若是用在烤爐時，則因用火烘烤食物最重要的就是 火候（火力和時間），*能正確調節燃氣流量，就難以控制 火力，結果會使每次食物烘烤出來的品質都不一樣。 【新型内容】 本創作的目的就是要在解決上述問題與缺點，而提供 • 一種電子控制的燃氣裔具，使燃氣器具的操作可以更為方 便，而且能夠精確地控制火候。 參 貫現本創作的燃氣器具，包含一電源裝置；至少一燃 燒态，至少一燃氣閥，以開閉該燃燒器的燃氣通路；與該 燃燒器數目相同的控制裝置，具有一操作裝置，從外部給 • 予命令信號；一微處理器，接收該操作裝置的命令信號， 、 並加以執行後輸出控制信號；及一燃氣閥控制裝置，接°收 該微處理器所給的控制信號，使該燃氣閥動作；與該燃燒 器數目相同的點火感應電極，設於該燃燒器的旁邊；及至 _ 少一點火感應裝置，接收該微處理器所給的控制信號，以 -

燃氣量指示裝置36及照明裝置38省略，並且刪除控制裝 - 置20中的定溫、定時功能，形成一僅具備火力調整及火力 顯示等基本功能的陽春型燃氣器具1〇e，以供應不同需求。 需知，在第1至第6圖所示實施例中，點火感應裝置32 和控制裝置28為各自獨立的模組，但事實上，點火感應裝 置32也可如第1B圖所示，併入控制裝置28c中，構成控制 裝置28c的一部分，形成一包含點火感應裝置的控制模組。 另外，可將第6圖中的燃燒器14、燃氣閥16、控制裝 M340421 置28及點火感應電極3〇的組合加以複製，提供一個具有 多個燃燒器14的燃氣器具10f(參見第7圖），俾對應地增加 所產生的熱量。 第7A圖顯示一與第7圖近似的燃氣器具1〇F。在本實 施例中，每一控制裝置28d包含一點火感應裝置32d，構 成一具有點火感應裝置的控制模組。 第8圖為本創作另一燃氣器具1〇g的結構方塊。該燃 氣器具10g除了具備第1圖所示燃氣器具1〇的全部技術特 徵之外，又包含二燃燒器14b、二燃氣閥16b、二點火感 應電極30b及二副控制裝置28b，並且具有一相同於第5圖 所示的邊爐40。其中，副控制裝置28b包含一副操作裝置 18b，具有一電源開關及火力鍵；一副微處理器2〇b，接 收副操作裝置18b的命令信號，並加以執行後輸出控制信 號，一燃氣閥控制裝置24b，接收副微處理器2〇b所給的 控制信號，使燃氣閥16b動作；及一副顯示裝置26b，由 副微處理器20b提供火力輸出顯示。 同樣的，可將第8圖所示燃氣器具i〇g的點火感應裝 置32併入控制裝置20中，並使每一副控制裝置28b各具有 一點火感應裝置32，分別接收其微處理器2〇和副微處理 器20b輸入的控制信號。 第9圖顯示本創作另一不同型式的燃氣器具1 〇h。本 實施例與第8圖所示燃氣器具1〇9的差異在於省略一組由 控制裝置28直接操控的燃燒器14及燃氣閥16，其餘構造 與第8圖所示的燃氣器具1〇g相同，不再說明。 17 M340421 第9A圖顯示一從第9圖變化而成的燃氣器具1〇H。在 本實鉍例中，上述燃氣器具1〇h的點火感應裝置32不再需 要，但使每一副控制裝置28e各具有一點火感應裝置32e ，分別接收其副微處理器20b輸入的控制信號。又，在第 9A圖中，該邊爐40的點火感應裝置32a也被併入副控制裝 置28f中，構成副控制裝置28f的一部分。 按照本創作的燃軋器具，因為使用電子控制，因此操 作容易’而且能夠精確地控制火候。 又，該燃氣器具提供顯示裝置，可以顯示使用狀態， 包括溫度、火力、定時關機時間、燃氣量不足等。“ 此外，該燃氣器具備有遙控裝置，可以遙控開/關機、 調節火力、設定溫度及及定時關機等。 當然，上述實施例可在不脫離本創作的範圍下加以若 干變化’故以上的說明所包含及附圖中所示的全部事項應 視為例示性，而非用以限制本創作的申請專利範圍。一 【圖式簡單說明】 第1圖為按照本創作第一實施例而成的燃氣器具 方塊圖。 第1A圖為第一實施例的電路圖。 第1B圖為與第彳圖近似的實施例結構方塊圖。 第2圖為本創作的第二實施例結構方塊圖。 第3圖為本創作的第三實施例結構方塊圖。 第4圖為本創作的第四實施例結構方塊圖。 第5圖為本創作的第五實施例結構方塊圖。 M340421 弟6圖為本創作的第六實施例結構方塊圖。 第7圖為本創作的第七實施例結構方塊圖。 第Μ圖為與第7圖近似的實施例結構方塊圖。 第8圖為本創作的第人實施例結構方塊圖。 第9圖為本創作的第九實施例結構方塊圖。 第9Α圖為與第9圖近似的實施例結構方塊圖。 第10圖為本創作的燃氣閥外觀圖。 第11圖為第10圖的燃氣閥處於閉閥位的軸方向（燃氣 流動方向）剖面圖。 弟12圖為弟1 〇圖的燃氣閥作動成開閥位的軸方向剖 面圖。 第13圖為與第1〇圖近似的燃氣閥外觀圖。 第14圖為第13圖的燃氣閥處於閉閥位的軸方向剖面 圖。 【主要元件符號說明】 10,10八，103,101)，10(：，1001，1(^，1(^，10「,109,10卜,101^..燃氣器具 12…電源裝置 14,14a，14b.··燃燒器 16,163,1613,16〇_"燃氣閥 18…操作裝置 18a，18b，18c…副操作裝置 20…微處理器 20a，20b...副微處理器 22…遙控裝置 19 M340421 22a...發射器 22b…接收器 24,24a，24b…燃氣閥控制裝置 26…顯示裝置 26a，26b，26c…畐丨J顯示裝置 28…控制裝置 283,2813,28〇,28(^，286,28尸..畐4控帝]裝置 30,30a，30b___點火感應電極 32,323,32〇1，326._.點火感應裝置 34…溫度偵測器 36.. .燃氣量指示裝置 38…照明裝置 40.. .邊爐 42…壓力開關 44·"光源 50,50a...殼體 52.. .流通路 54···第一裝酉己口 56·"第二裝配口 58,58a·"流入口 60,60a…流出口 62,62a···流入側接頭 64,64b...流出侧接頭 66···中心軸線 20 M340421M340421 VIII. New description: [New technical field] This creation is about a gas appliance, especially a gas appliance that is easy to operate and can control the heat. [Prior Art] Commercially available gas appliances, such as gas stoves and barbecue stoves, generally employ a piezoelectric automatic ignition device. The piezoelectric automatic ignition device uses the piezoelectric phenomenon to generate a spark, and the energy of the spark is used for gas. The so-called piezoelectric is that the piezoelectric element is subjected to pressure or tensile stress to generate electricity, and the electric electricity generated by this method is called piezoelectric phenomenon. The action of the piezoelectric ignition device is to rotate the cork knob and mount the protrusion on the same shaft as the cork, that is, lift the shot, and at the same time, the gas flows out from the nozzle and then rotates when the cork is slowly opened. When the knob is raised, the protruding member of the hammer is disengaged, and the hammer is struck by the restoring force of the spring to the metal casing with the piezoelectric element. The piezoelectric element generates a high voltage and conducts the high voltage to the ignition electrode via the conductive wire to cause a spark. At this time, the gas that has flowed out of the nozzle around the electrode is filled with the mixed gas that has reached the ignition range, so that the gas is lit. Since the piezoelectric ignition device must be turned by a human hand to turn the ignition knob, the gas appliance is not very convenient to operate. On the other hand, in the process of using gas appliances, most of them belong to the control and regulation of gas, from the supply of gas to the conversion of gas into heat. Although the above-mentioned cork has the function of regulating the gas flow rate, since it is a hand to turn the cork knob, it is difficult to accurately generate the throttling effect. The fact that this 5 M340421 does not have much influence on the cooking utensils for cooking, but if it is used in the oven, the most important thing is to use the fire to bake food (firepower and time), * can Correctly adjusting the gas flow rate makes it difficult to control the firepower, and as a result, the quality of each food baked will be different. [New content] The purpose of this creation is to solve the above problems and shortcomings, and to provide an electronically controlled gas appliance that makes the operation of the gas appliance more convenient and accurately controls the heat. The gas appliance according to the present invention comprises a power supply device; at least one combustion state, at least one gas valve for opening and closing the gas passage of the burner; and the same number of control devices as the burner, having an operating device Giving a command signal from the outside; a microprocessor receiving a command signal of the operating device, and executing the output control signal; and a gas valve control device receiving the control given by the microprocessor a signal for causing the gas valve to operate; an ignition sensing electrode having the same number as the burner is disposed beside the burner; and to _ less one ignition sensing device, receiving a control signal given by the microprocessor, to supply A current is drawn to the ignition sensing electrode, where a spark is generated to combust the gas-gas mixture to form a flame, and the discharge is stopped upon receiving the flame signal fed back by the ignition sensing electrode, and the flame signal is input to the microprocessor. The gas appliance in turn includes the same number of sub-operating devices as the burner, and each of the sub-operating devices can individually give the microprocessor a command number. The gas is further provided with the same number of display devices as the number of sub-operating devices, and the microprocessor provides an output display.

A gas valve 16 for opening and closing the passage of the gas to the burner 14 (hereinafter referred to as a gas passage). An operating device 18, which gives a command signal from the outside, is the main part of the gas appliance 10. One of the input devices has a power switch PB1 for turning on/off; a fire button PB2 is used to enter the heating mode; a certain temperature button PB3 is used to set the constant temperature mode; when the button PB4 is selected, the timed shutdown mode is selected to enable > Upward adjustment key PB5, downward adjustment key PB6 for adjusting the firepower, temperature and time upwards and downwards; and a lighting switch PB7 for controlling the light source 44 to be turned on and off. Further, a touch device (not shown) may be used. In place of the above-described operating device 18', the touch device has a touch |c, and a touch panel that can receive a signal input from a contact (such as a finger or a plastic pen tip) instead of a mechanical button panel. A microprocessor 20 is a device that receives and executes instructions from the operating device 18. > A remote control device 22, which is the same as the operating device 18, is an input device for the gas appliance. The above operations such as on/off, firepower adjustment, temperature setting, timed shutdown, and illumination of the light source 44 can be operated by radio frequency (RF) or infrared (|R) remote control device 22. The remote control unit 22 has a transmitter 22a for transmitting a data code, and a receiver 22b receives the data code, decodes it, and transmits it to the microprocessor 20. It is to be understood that in the embodiment of Fig. 1, the gas appliance 1 can be operated by the remotely operated operating device 18 and the wirelessly controlled remote control unit 22. Of course, the gas appliance 10 can also provide only one of the modes of operation as needed. 11 M340421 A gas valve control device 24 receives a control signal input from the microprocessor 20 to cause the gas valve 16 to open and close to open and close the gas passage. A display device 26 is provided with an output display by the microprocessor 20 for displaying information such as firepower, temperature, timed shutdown time, gas inventory, and the like.

An ignition sensing device 32, when the microprocessor 20 receives the command signal that the power switch PB1 is on, sends a control signal to the gas valve control device 24 and the ignition sensing device 32, the former opening the gas valve 16 to release The gas is discharged to the burner 14, which supplies a high voltage current to the ignition sensing electrode 30. These high voltage exciting currents generate a spark on the ignition sensing electrode 30, which in turn ignites a mixture of gas and air to form a flame, and then ignites the induction. The electrode 30 returns the detected flame signal to the ignition sensing device 32 to stop discharging (ignition), and the flame signal is input to the microprocessor 20 via the ignition sensing device 32. If the ignition is not successful, the microprocessor 20 will immediately discharge the ignition sensor 32 for a few seconds. If the flame signal is still not detected, the circuit connected to the gas valve control device 24 is cut off, and the gas valve 16 12 M340421 is turned off. , stop releasing gas and keep it in standby. The ignition sensing device 32 is used for hot water gas appliances. The technical content can be referred to Taiwan New Patent No. 143956, and will not be described. A port temperature detector 34 is installed at a temperature detecting position of the gas appliance 1〇, and the detected ## is added to the microprocessor 2〇, so that the gas valve control device 24 generates a predetermined action, and then goes The gas valve 16 is driven to regulate the gas flow for temperature control purposes. The temperature sensor 34 can employ a thermistor or other suitable temperature sensing element. > A gas amount indicating device 36 comprising a pressure switch 42 connected to the microprocessor 20. When the gas pressure drops, the pressure switch 42 is turned on to cause the microprocessor 20 to output a control signal to display an ideographic symbol or text that is about to be exhausted on the display device 26. A lighting device 38, comprising a light source 44, provides illumination required for the nighttime use of the gas appliance. The illumination device 38 controls the illumination of the light source 44 by the microprocessor 20 based on the signal given by the illumination switch PB7. The light source 44 > can be a tube or a bulb. The gas valve 16 is composed of a casing 5 and a first solenoid valve 70a and a second solenoid valve 70b as shown in Figs. 10 and 11. Wherein, a gas flow passage 52 is formed inside the casing 50, and the first fitting port 54 and the second fitting port 56 respectively communicate with the flow passage 52 having the inflow port 58 and the outflow port 60 at the same central axis 66. And the inflow port 58 and the outflow port 60 are respectively formed with a thread or other type of inflow side joint 62 and an outflow side joint 64 for connecting a gas pipe (not shown), the former connecting the gas source via the gas pipe, and the latter passing the gas pipe The burner 14 is connected. The first fitting opening 54 13 M340421 and the second fitting opening 56 are symmetrically disposed above and below the housing 50 and between the inflow port 58 and the outflow port 60. The first solenoid valve 70a is mounted to the first fitting port 54, and the second solenoid valve 70b is attached to the second fitting port 56 to open and close the flow passage 52, respectively. In order to make the first electromagnetic valve 70a and the second electromagnetic valve 70b having the same configuration can generate different throttling effects on the gas flow rate in the flow passage 52, the inner diameter of the air outlet hole 72a of the first electromagnetic valve 70a may be smaller or larger than the first The inner diameter of the air outlet hole 72b of the second electromagnetic valve 70b; or as shown in Fig. 11, a first bushing 74a is attached to the air outlet hole 72a of the first electromagnetic valve 70a, and a first bushing 74b is attached to the air outlet hole 72b of the second electromagnetic reading 70b. The second bushing 74b has an inner diameter larger than the inner diameter of the hole 76a of the first outer sleeve 74a. Thus, the three types of throttle control can be generated by the individual actions and simultaneous actions of the first solenoid valve 70a and the second solenoid valve 70b. It is understood that when the valve body 78a of the first solenoid valve 7〇a is opened, only a small amount of gas flows into the orifice 82a via the intake hole 80a, and then flows out from the bore 76a of the first bushing 74a, and then from the flow passage 52. The outflow port 60 flows out to supply the combustion; when the valve body 78b of the second solenoid valve 70b is opened, the medium amount of gas is allowed to flow into the port 82b via the intake hole 80b, and then flows out from the hole 76b of the second bushing 74b, and then The supply of combustion is used from the outflow port 60 of the flow path 52; when the valve bodies 78a and 78b of the first solenoid valve 7〇a and the second solenoid valve 70b are simultaneously actuated to open the valve position (see Fig. 12), A plurality of gas flows into the channels 82a and 82b via the intake ports 80a and 80b, respectively, and then flow out from the holes 76a and 76b, and then flow out from the outflow port 60 of the flow path 52 to supply combustion requirements, so that the gas appliance 1 can be depressed. The keys on the operating device 18 adjust the amount of firepower. According to this embodiment, a total of three firepowers are available for adjustment. Of course, as the number of solenoid valves increases, the number of fire regulation segments will increase relatively. Further, the flow path 52 is not limited by one outflow port 60, and there may be two or more outflow ports 6〇. Further, the inner diameter of the hole 76b of the second bushing 74b may be made smaller than the inner diameter of the hole 76a of the first bushing 74a. Figures 13 and 14 show the appearance and internal configuration of a gas valve 16c which is similar to the first and second figures, respectively. The main difference between the present embodiment and the gas valve 16 described above is that the inflow side joint 62a and the outflow side joint 64a at the two ends of the body 50a are different in type, and the inflow port 58a and the outflow port 60a are not disposed at the same central axis and are spaced apart by 90 degrees.
