Description
本發明係與瓦斯爐具有關,更詳而言之是指一種瓦斯爐及其燃燒控制方法。The present invention is related to a gas furnace, and more specifically to a gas furnace and a combustion control method thereof.
按,瓦斯爐是最常用於烹煮食材的加熱器具,相較於電磁爐等將電能轉換為熱能的加熱器具,瓦斯爐的控制方式簡單,且燃燒瓦斯所產生的熱能大於使用電力產生的熱能,可有效減少烹煮的時間。According to the gas stove, the gas stove is the most commonly used heating material for cooking food. Compared with the induction cooker, which converts electrical energy into heat energy, the control mode of the gas furnace is simple, and the heat energy generated by burning gas is greater than the heat energy generated by using electricity. It can effectively reduce the cooking time.
圖1所示者為習用的瓦斯爐1之結構,包含有一爐體10、一燃燒器12、一連接該燃燒器12的混合管14、以及一連接瓦斯來源的噴嘴16。該爐體10具有一開口102連通該爐體10內部與外部。該燃燒器12位於該爐體10內,且其具有複數個火焰孔122朝向該開口102。該混合管14具有複數個入氣孔142。當瓦斯通過該噴嘴16時,將空氣自該些入氣孔142引入該混合管14中,產生第一次混合,再由該混合管14輸送至該燃燒器12與該些火焰孔122周圍的空氣進行第二次混合並燃燒。該燃燒器12所產生的熱能係與瓦斯量及空氣量的比例有關,當瓦斯量與空氣量達到一較佳的比例時,該燃燒器12產生的熱效率相對較高。The structure of the conventional gas furnace 1 shown in Fig. 1 comprises a furnace body 10, a burner 12, a mixing tube 14 connecting the burners 12, and a nozzle 16 connected to the gas source. The furnace body 10 has an opening 102 communicating with the inside and the outside of the furnace body 10. The burner 12 is located within the furnace body 10 and has a plurality of flame holes 122 facing the opening 102. The mixing tube 14 has a plurality of air inlet holes 142. When the gas passes through the nozzle 16, air is introduced into the mixing tube 14 from the air inlet holes 142 to generate a first mixing, and then the mixing tube 14 is sent to the air around the burner 12 and the flame holes 122. Perform a second mixing and burn. The thermal energy generated by the burner 12 is related to the ratio of the amount of gas and the amount of air. When the amount of gas and the amount of air reach a preferred ratio, the thermal efficiency of the burner 12 is relatively high.
習用的瓦斯爐1之瓦斯與空氣混合的方式所獲得的空氣量 有限,因此燃燒效率無法提升。當烹煮食物所需的熱能較高時,只能利用提供更多的瓦斯量,讓火焰增大,進而增加鍋具的受熱面積,以達到所需的熱能。然,提供更多瓦斯量代表耗費的瓦斯更多,在石化燃料日漸短缺的今日,無法有效節省瓦斯用量。火焰增大更易造成人員燒傷或引燃瓦斯爐附近的易燃物。此外,在所獲得的空氣量有限的前提下,單獨提高瓦斯量將造成瓦斯燃燒不完全,此將導致一氧化碳增加,若未有良好的通風環境恐有造成人員一氧化碳中毒之虞。再者,由於燃燒瓦斯時需由該燃燒器12的火焰孔122周圍獲取空氣,因此,該燃燒器12的周圍必須呈開放狀態,此將使得熱能由該燃燒器12周圍逸散,導致熱能損耗,無法有效利用瓦斯燃燒後產生的熱能。The amount of air obtained by mixing the gas of the gas furnace 1 with air Limited, so the combustion efficiency can not be improved. When the heat energy required for cooking food is high, it is only possible to provide more gas volume and increase the flame, thereby increasing the heating area of the pan to achieve the required heat energy. However, providing more gas represents more gas consumption, and today, with the growing shortage of fossil fuels, it is impossible to effectively save gas consumption. Increasing the flame is more likely to cause people to burn or ignite flammable materials near the gas stove. In addition, under the premise that the amount of air obtained is limited, increasing the gas volume alone will result in incomplete combustion of gas, which will lead to an increase in carbon monoxide. If there is no good ventilation environment, it may cause carbon monoxide poisoning. Moreover, since air is required to be collected from the flame hole 122 of the burner 12 when burning the gas, the periphery of the burner 12 must be in an open state, which causes heat energy to escape from the periphery of the burner 12, resulting in loss of heat energy. The heat generated by the combustion of gas cannot be effectively utilized.
有鑑於此,本發明之主要目的在於提供一種瓦斯爐及其燃燒控制方法,可有效提高瓦斯爐的熱效率,減少熱能逸散,節省瓦斯的用量。In view of this, the main object of the present invention is to provide a gas furnace and a combustion control method thereof, which can effectively improve the thermal efficiency of the gas furnace, reduce thermal energy dissipation, and save the amount of gas.

Wherein the furnace body has a first chamber and a second chamber, wherein the first chamber has an upper opening; the burner has a plurality of flame holes in the first chamber; the blower Used to introduce air to the burner; the gas regulator is arranged to be connected to One of the burners is on a gas line for regulating the flow of gas to be supplied to the burner.
依據上述構思,本發明更提供有該瓦斯爐之之燃燒控制方法,包含下列步驟:A.在該第二容室控制瓦斯與空氣混合,其中混合的瓦斯量與空氣量係呈正比;B.將混合後的瓦斯與空氣引入該燃燒器中,並由該些火焰孔進入該第一容室中;以及C.點燃由該些火焰孔進入該第一容室中的瓦斯。According to the above concept, the present invention further provides a combustion control method for the gas furnace, comprising the following steps: A. controlling gas and air mixing in the second chamber, wherein the mixed gas volume is proportional to the air volume; Mixing gas and air into the burner and entering the first chamber from the flame holes; and C. igniting gas entering the first chamber from the flame holes.
藉此,透過該瓦斯爐及其燃燒控制方法,可達到同時讓一定量的空氣與一定量的瓦斯進入燃燒器混合燃燒,有效提高燃燒瓦斯的熱效率,並且可蓄積燃燒瓦斯後產生的熱能,減少熱能逸散,讓熱能更有效利用。Thereby, through the gas furnace and its combustion control method, a certain amount of air can be mixed with a certain amount of gas to enter the burner, thereby effectively improving the thermal efficiency of the combustion gas, and accumulating the heat energy generated after burning the gas, reducing Heat is dissipated, allowing heat to be used more efficiently.

該調節閥60包括有一第二閥體62與一第二閥門64。其中,該第二閥體62結合於該第一閥體52上,該第二閥體62包含有一開口624與一洩壓口625。該第二閥門64包含有一彈性膜66與一連桿68,該彈性膜66設於該第二閥體62中,且該彈性膜66將該第二閥體62分隔成互不相通的一第一氣室622與一第二氣室623。該第一氣室622連通該開口624,且該開口624透過一導風管72連通該混合器30的第一延伸管36。該第二氣室623連通該第一閥體52的第二孔道527以及透過該洩壓口625連通該第一閥體52的第二氣室525。該連桿68一端結合於該彈性膜66上,另一端通過該洩壓口625,該連桿68可為該彈性膜66帶動而於圖5所示之一第一位置P1與圖7所示之一第二位置P2之間往復移動,藉以封閉或開啟該洩壓口625。前述之該洩壓口625、該第二氣室623與該第一閥體52上的第二孔道527共同構成圖6所示之一洩壓通路70,該第二閥門64位於該洩壓通路70之路徑上。The regulating valve 60 includes a second valve body 62 and a second valve 64.

The second valve 64 includes an elastic membrane 66 and a connecting rod 68. The elastic membrane 66 is disposed in the second valve body 62, and the elastic membrane 66 divides the second valve body 62 into a non-intersecting one. An air chamber 622 and a second air chamber 623. The first air chamber 622 communicates with the opening 624, and the opening 624 communicates with the first extension tube 36 of the mixer 30 through an air duct 72. The second air chamber 623 communicates with the second hole 527 of the first valve body 52 and the second air chamber 525 that communicates with the first valve body 52 through the pressure relief port 625. One end of the connecting rod 68 is coupled to the elastic film 66, and the other end passes through the pressure releasing port 625. The connecting rod 68 can be driven by the elastic film 66 in a first position P1 shown in FIG. 5 and shown in FIG. One of the second positions P2 reciprocates to close or open the pressure relief port 625. The pressure relief port 625, the second air chamber 623 and the second channel 527 on the first valve body 52 together form a pressure relief passage 70 as shown in FIG. 6, and the second valve 64 is located in the pressure relief passage. On the path of 70.
當該鼓風機40未為運轉時,該第二閥門64的連桿68位於該第一位置P1,該連桿68封閉該洩壓口625(圖5參照),亦即阻斷該洩壓通路70,此時該控制閥50的第一氣室524與第二氣室525之氣壓相等,該第一閥門54為 該彈簧56推抵而接觸該通道口523,阻斷該主瓦斯通路58。When the blower 40 is not in operation, the link 68 of the second valve 64 is located at the first position P1, and the link 68 closes the pressure relief port 625 (refer to FIG. 5), that is, blocks the pressure relief passage 70. At this time, the first air chamber 524 of the control valve 50 is equal to the air pressure of the second air chamber 525, and the first valve 54 is The spring 56 pushes against the passage opening 523 to block the main gas passage 58.
請參閱圖6與圖7,當該鼓風機40運轉時,該鼓風機40產生的風壓由該混合器30灌入該調節閥60的第一氣室622,形成一作用力F將該彈性膜66連同該連桿68往該第二氣室623的方向推擠,連帶地將該連桿68推往該第二位置P2,使該連桿68與該洩壓口625之間產生間隙D(圖7參照),開啟該洩壓通路70。此時,該第二氣室525的瓦斯自該洩壓通路70流通至該第一閥體52的出口端522,使得該控制閥50的第二氣室525之氣壓下降,該第二氣室525比該第一氣室524的氣壓相對較低,因而形成一壓力差。當該壓力差大於該彈簧56推抵該第一閥門54的力量時,該第一閥門54被推往該第二氣室525,開啟該主瓦斯通路58,使得瓦斯得通過該瓦斯調節器48並進入該混合器30中,以便與來自該鼓風機40的一部分之空氣進行混合。Referring to FIG. 6 and FIG. 7, when the blower 40 is in operation, the wind pressure generated by the blower 40 is poured into the first air chamber 622 of the regulating valve 60 by the mixer 30 to form a force F to the elastic film 66. Pushing the connecting rod 68 toward the second air chamber 623, and pushing the connecting rod 68 to the second position P2, so that a gap D is generated between the connecting rod 68 and the pressure releasing port 625 (Fig. 7)), the pressure relief passage 70 is opened. At this time, the gas of the second air chamber 525 flows from the pressure release passage 70 to the outlet end 522 of the first valve body 52, so that the air pressure of the second air chamber 525 of the control valve 50 is lowered, and the second air chamber 525 is relatively lower than the air pressure of the first plenum 524, thus creating a pressure differential. When the pressure difference is greater than the force of the spring 56 pushing against the first valve 54, the first valve 54 is pushed to the second air chamber 525, opening the main gas passage 58 so that the gas passes through the gas regulator 48. And entering the mixer 30 for mixing with air from a portion of the blower 40.
據上所述可知,藉由控制該鼓風機40風扇46的轉速,以產生不同的風壓即可間接控制該第一閥門54的開啟程度,進而調節供輸至該混合器30的瓦斯流量。As can be seen from the above, the degree of opening of the first valve 54 can be indirectly controlled by controlling the rotational speed of the blower 40 fan 46 to generate different wind pressures, thereby adjusting the flow rate of gas supplied to the mixer 30.
該操控裝置74包含有一以旋鈕742為例的操作介面,以及一控制器744。該旋鈕742供使用者調整該風扇46的轉速,該控制器744電性連接該鼓風機40且依據該旋鈕742的轉動 幅度送出相對應的電壓予該鼓風機40,藉以控制該風扇46的轉速。藉此,使用者透調整該旋鈕742,即可控制該燃燒器28的火力大小。The manipulation device 74 includes an operation interface exemplified by a knob 742, and a controller 744. The knob 742 is used by the user to adjust the rotation speed of the fan 46. The controller 744 is electrically connected to the blower 40 and is rotated according to the knob 742. The amplitude sends a corresponding voltage to the blower 40, thereby controlling the rotational speed of the fan 46. Thereby, the user can control the firepower of the burner 28 by adjusting the knob 742.
在上述中,瓦斯與空氣在進入該燃燒器28之前,在該第二容室22中就先行混合,因此,該燃燒器28燃燒瓦斯時並不需再由該些火焰孔282周圍取得空氣,所以,該燃燒器28的火焰孔282可位於該爐體18的第一容室20中。將自該些火焰孔282進入該第一容室20的瓦斯以一點火器(圖未示)點燃後產生熱能,所產生的熱能可蓄積在該第一容室20中,且熱能透過該上方開口202傳遞至該鍋體P。更值得一提的是,該鍋體P置於該爐架24上時,該第一容室20、該隔熱片26與該鍋體P底部共同形成的燃燒空間S更能將熱能集中,避免熱能逸散。瓦斯燃燒後在該燃燒空間S產生的壓力則可透過該些排氣孔262釋放壓力,而燃燒後的水氣及二氧化碳亦由該排氣孔262排出。In the above, the gas and the air are mixed first in the second chamber 22 before entering the burner 28. Therefore, the burner 28 does not need to obtain air from the flame holes 282 when burning the gas. Therefore, the flame hole 282 of the burner 28 can be located in the first chamber 20 of the furnace body 18. The gas entering the first chamber 20 from the flame holes 282 is ignited by an igniter (not shown) to generate thermal energy, and the generated heat energy can be accumulated in the first chamber 20, and the heat energy is transmitted through the upper opening. 202 is delivered to the pot P. It is more worth mentioning that when the pot body P is placed on the hob 24, the combustion space S formed by the first chamber 20, the heat insulating sheet 26 and the bottom of the pot body P can concentrate heat energy. Avoid heat dissipation. The pressure generated in the combustion space S after the combustion of the gas can release the pressure through the exhaust holes 262, and the burned moisture and carbon dioxide are also discharged from the exhaust hole 262.
在實務上,亦可使該隔熱片26頂緣的低於該爐架24的頂緣,讓該鍋體P底部與該隔熱片26之間具有縫隙,則可視縫隙的大小依需求設置該些排氣孔262,若縫隙的大小足夠釋放壓力則不需設置該些排氣孔262。此外,若使用支撐力佳的隔熱片來支撐該鍋體P,亦可不需設置該爐架24。In practice, the top edge of the heat insulating sheet 26 may be lower than the top edge of the furnace frame 24, so that there is a gap between the bottom of the pot body P and the heat insulating sheet 26, and the size of the visible gap is set according to requirements. The venting holes 262 do not need to be provided if the size of the slits is sufficient to release the pressure. Further, if the heat insulating sheet having a good supporting force is used to support the pot body P, the hob 24 may not be provided.
以下再提供另一可達到相同上述效果的具體實施例,其中: 圖8與圖9所示者為本發明第二較佳實施例之瓦斯爐3,具有相同於上述第一較佳實施例之爐體18、爐架24、隔熱片26、燃燒器28與鼓風機40,以及不同於上述實施例之一混合器80、一瓦斯調節器86與一操控裝置88。Another specific embodiment that achieves the same effects described above is further provided below, wherein: 8 and FIG. 9 is a gas furnace 3 according to a second preferred embodiment of the present invention, having a furnace body 18, a furnace frame 24, a heat insulating sheet 26, and a burner 28 which are identical to the above-described first preferred embodiment.

該瓦斯調節器86係設置於連通至該混合器80之一瓦斯管路90上,用以調節供輸至該混合器80的一瓦斯流量。在本實施例中,該瓦斯調節器86係以一比例閥為例,但不以此為限。該比例閥係利用所提供的電流使閥門作比例式開啟,亦即當電流提供越大,閥門開度比例式地增大,所提供之瓦斯流量亦比例式地增大,當然在設計上,亦可利用其他機構之設計,例如以步進馬達控制閥門開啟程度之方式,重要的是可控制及計算出通過的瓦斯流量。該瓦斯調節器86具有一入口端862與一出口端864,該入口端862連通該瓦斯管路90,該出口端864連通該混合器80的延伸管84。由該混合器80的側口824注入的瓦斯進入該主通道828;由該進氣口822注入的空氣將該側口824周圍的瓦斯往該出氣口826的方向牽引並混合,輸出 至該燃燒器28。The gas regulator 86 is disposed in communication with a gas line 90 of the mixer 80 for regulating a flow of gas to the mixer 80. In this embodiment, the gas regulator 86 is exemplified by a proportional valve, but is not limited thereto. The proportional valve utilizes the supplied current to cause the valve to be proportionally opened, that is, when the current supply is larger, the valve opening degree is proportionally increased, and the supplied gas flow rate is proportionally increased, of course, in design, Other mechanisms can also be used, such as the stepper motor to control the degree of valve opening, it is important to control and calculate the flow of gas through. The gas regulator 86 has an inlet end 862 that communicates with the gas line 90 and an outlet end 864 that communicates with the extension tube 84 of the mixer 80. The gas injected from the side port 824 of the mixer 80 enters the main passage 828; the air injected by the air inlet 822 pulls and mixes the gas around the side port 824 toward the air outlet 826, and outputs To the burner 28.
該操控裝置88包含有一以旋鈕882為例的操作介面以及一電控單元884。其中:該電控單元884分別電性連接該旋鈕882、該鼓風機40與該瓦斯調節器86。該旋鈕882供使用者調整該燃燒器28的火力大小,該電控單元884依據該旋鈕882的轉動幅度送出相對應的電流予該瓦斯調節器86,以及相對應的電壓予該鼓風機40,藉以控制供輸至該混合器80的瓦斯流量以及驅動該風扇46引入空氣。當旋鈕882的轉動幅度愈大,輸送到混合器80的空氣量與瓦斯量也相對的增加,藉此,使用者透調整該旋鈕882,即可控制該燃燒器28的火力大小。The operating device 88 includes an operating interface exemplified by a knob 882 and an electronic control unit 884. The electric control unit 884 is electrically connected to the knob 882, the blower 40 and the gas regulator 86, respectively. The knob 882 is used by the user to adjust the firepower of the burner 28. The electronic control unit 884 sends a corresponding current to the gas regulator 86 according to the rotation amplitude of the knob 882, and the corresponding voltage is applied to the blower 40. The gas flow to the mixer 80 is controlled and the fan 46 is driven to introduce air. When the rotation amplitude of the knob 882 is larger, the amount of air and the amount of gas delivered to the mixer 80 are also relatively increased, whereby the user can adjust the amount of firepower of the burner 28 by adjusting the knob 882.
在本實施例中,透過分別控制該瓦斯調節器86與該鼓風機40,同樣可讓一定量的瓦斯與一定量的空氣在進入該燃燒器28之前就先行混合,點燃瓦斯後,瓦斯在該燃燒空間S中燃燒,讓熱能更加集中。In this embodiment, by separately controlling the gas regulator 86 and the blower 40, a certain amount of gas and a certain amount of air can be mixed before entering the burner 28, and after the gas is ignited, the gas is burned. The space S burns to make the heat more concentrated.
本發明之瓦斯爐預先混合瓦斯與空氣提高瓦斯燃燒效率,並且再利用爐體的第一容室蓄積燃燒器所產生的熱能,讓瓦斯產生的熱能更有效利用,藉以達到節省瓦斯之目的。此外,隔熱片除了可避免熱能逸散之外,更可避免火焰竄出,造成人員燒傷或引燃瓦斯爐附近的易燃物。The gas furnace of the invention premixes gas and air to improve gas combustion efficiency, and reuses the heat energy generated by the first chamber of the furnace to accumulate the heat energy generated by the gas, so that the heat energy generated by the gas can be more effectively utilized, thereby achieving the purpose of saving gas. In addition, in addition to avoiding thermal energy dissipation, the heat shield can prevent flames from escaping, causing burns or igniting flammable materials near the gas stove.
