Conventionally, this type of gas furnace is provided with an operation section in front of the furnace body to operate a gas furnace that contains a gas burner housed in the furnace body (see Patent Document X. Since the operation section is located in front of the furnace body, it is not subject to combustion. The thermal influence of the device, but because of being located under the fluid table, the operability is poor. 2220 means that the embedded body of the furnace body is opened in such a fluid table, not only need to be provided in front of the fluid table to face the operating part. It also takes time to install a furnace toward the countertop. Therefore, for example, there is a structure in which a panel is arranged in an operation section as shown in FIGS. 18 and 19 (see Patent Document 2). In this structure, The main body box M 15 is formed in a box shape with an upper opening, and a flange portion 51 ′ on an outer peripheral edge of an upper end thereof can be inserted into a mounting hole 52 a formed in a kitchen countertop 52. The upper side of the main body phase 51 is provided with a mounting plate 53. A pair of combustion openings 53a 'are formed on the rear part and a pair of operation shaft through holes 53b for the operation part are formed in the front part. Corresponding to the burner openings 53a, the body box "is provided with For a gas combustion state of 20, a flame holder 55 is installed around the two burner openings 53a. A pair of ignition and firepower devices (gas cocks) 56 (gas cocks) are arranged in the center of the front part of the main body box 51 for 5 weeks. The ignition and firepower adjustment of each gas burner 54 is implemented. In addition, the operation shafts 56a pass through the operation shaft through holes 53b of the panel 53 above the panel 53 and are on the panel 53. The operation knob y is installed in each of 1232921. The shaft 56a becomes an operation portion. By operating these operation knobs by rotation, the ignition and thermal power adjustment device 56 can be operated to perform the ignition operation or thermal power adjustment of each gas burner 54. Patent Document 1 Japanese Patent Application Laid-Open No. 10-89704 Document 2 Japanese Unexamined Patent Publication No. 58-186302 In this gas furnace, since the operation portion is disposed on the panel, the operability is improved. However, as described above, the operation knob 57 is disposed to protrude above the panel 53. 10 Therefore, When the gas burner 54 is used for heat treatment, especially when using a large pot, the operation knobs 57 are affected by heat, the operation knob becomes hot and it is difficult to operate, and the operation knob is changed. In addition, when such a heating process is performed, the operation knobs 57 will hinder the cooking operation, especially for a pot that is large and heavy, such as a Chinese pot, and the bottom of the operation knob 57 will encounter the operation knob 57, so it will feel uncomfortable. Impact, or inconvenience caused by the operation knob 57 or the ignition and fire power adjustment device 56. Moreover, when the panel is cleaned, there is also a problem that the operation knob 57 hinders the operation. In addition, the operation can be formed on the panel 53 Through holes 53b for shafts, boiled soup overflows, etc., may enter the main body box 51 through the through holes 53b, which may cause failures in internal components such as the ignition and thermal adjustment devices 56 and the like. The heat effect on the operation knob 57 during heating cooking is shown by the double-dotted dotted lines in FIGS. 18 and 19. A heat shield 58 is erected between the operation knob 57 and the gas burner 54 and on the panel 53. Make up. However, when the heat shielding plate 58 is provided in this manner, the number of parts increases. 1232921 In addition, if the panel 53 is a glass plate, the heat shielding plate 58 cannot be formed integrally with the panel 53. Therefore, a hole is made in the face plate 53 and the heat shielding plate 58 is assembled into the main body box 51 through the hole. This not only increases the number of parts, but also makes the gas furnace assembly troublesome. In addition, when the cooking or cleaning panel 53 is heated, both the operation knob 57 and the heat shielding plate 58 cause obstacles, making the cleaning operation more troublesome. In addition, since the heat shield plate 58 is provided, the upper surface of the panel 53 cannot be widely used. Moreover, when a large pan or grilled wire for grilled food is used, the ease of use is reduced. The heat shielding plate 58 may feel uncomfortable as described above. The present invention has been made with a view to such controversial points as exist in the conventional technology, and its main object is to provide a gas furnace capable of eliminating various inconveniences caused by operating knobs or protruding panels of a heat shield. Furthermore, the purpose is to provide a kind of gas stove that does not need to be formed on the panel. Operation: through-holes, overflowing soups, etc. that enter the through-holes and cause failure of the built-in I pieces. C ^ -Mingchi]

接著，按照第8圖及第9圖說明前述瓦斯爐之迴路構成 及動作。第9圖所示之流程圖係根據記憶體32内之程式數 據，進行控制裝置31之控制者。在與第丨丨圖等所示之該實 施形態不同的實施形態之流程圖中也是同樣的。 又，在該瓦斯爐之控制裝置31上，連接有直流電源59， 20 並且連接有用以作動各閥28、29A、29B及各點火哭33A、 33B之交流電源60。而且，由操作者接觸操作操作部4〇A， 由電源開關38A檢出其操作狀態時，由控制裝置31點亮電源 顯示燈39A。接著，接觸操作操作部4〇B、40C，由點媳火 開關38B、38C檢出其操作狀態時，利用控制裝置31開放閥 16 1232921 28、29A、29，並且作動點火器33A、33β 使瓦斯燃燒器 24Α、24Β可點火。 此時，由控制裝置31可構成誤動作防止裝置，開關38八 〜38G檢出在面板22上有異物或小動物等操作者以外的東 5西時，控制裝置31不會做誤動作。亦即，在第9圖所示之程 式中，可判別電源開關38Α是否單獨以兩秒鐘連續操作（步 驟S1)，在不能以兩秒鐘以上連續單獨操作時則不施加前述 交流電源60。而且，若藉由電源開關38Α連續操作兩秒鐘以 上，施加交流電源60，則可判別點熄火開關38B、38c是否 10 操作（步驟S2)。 於該判別中，在點熄火開關38B、38C不能操作時，判 別是否從電源開關38A之操作開始已經過15秒鐘（步驟 S3)。而且，在操作電源開關38A已經過15秒鐘以上時，交 流電源60被切斷而回到初期狀態。對此，在操作電源開關 15 38A開始操作點熄火開關38B、38C15秒以内時，實施點火 動作（步驟S4)。 因而，在面板22之操作部40A〜40G上載置有紙或布等 異物，使電源開關38A及點熄火開關38B、38C成為同時操 作之狀態時或僅電源開關38A繼續操作狀態時，沒有由控制 20 裝置31輸出點火動作信號至閥28、29A、29B及點火器33 A、 33B之情形。又，即使蟑螂或老鼠等小動物在面板22之操作 部40A〜40G上移動，使電源開關38A變成僅在短時間操作 之狀態，也沒有由控制裝置31輸出點火動作信號之情形。 因而，能防止因開關38A〜38G檢出面板22上有異物或小動 17 1232921 物等操作者以外的東西，而誤將瓦斯燃燒器2从、細點火。 再者，在该瓦斯燃燒器24A、24B之點火時，譬如，不 論熄火時的火力強度為何，在由瓦斯量調節闊29八、2犯產 生的火力調節狀係在複數個階段（譬如五階段）之中，設定在 5中狀調節狀態（譬如，五階段之中之三級3)，作為點火時 之適田瓦斯i。因此，在有需要變更火力時，只要操作火 力增強開關38D、38E或火力減弱開關38F、38G，則由控制 裝置31作動瓦斯量調節閥29A、29B，以將火力從中間之調 節狀態增強調節或減弱調節。 10 此日守，藉由岫述控制裝置31構成動作限制裝置，且即 使操作者為增強火力而由操作部4〇D、備連續操作開關 38D 38E也不⑤進行對應其連續操作之火力增強控制動 作。亦即，前述火力增強開關38D、38E藉由每一次之操作 使火力朝每-階段可增強之方向變更，即使連續操作，控

As shown in FIGS. 4 and 7, the bottom of the main body box 21 is an intermediate portion between the two gas burners 24A and 24B, and a control box 30 is arranged at the front end side. The control box 3〇 As shown in Figure 8, it can be installed with a main on-off valve 28 for controlling various actions such as two gas thieves ⑽, igniting, or fire power adjustment, or as a control part for controlling the gas volume adjustment valves 29A, 29B, etc. Device 31 or a memory 32 that memorizes the program data or temporary working data of the control device 31. In the body box bottom 4 controls the positions of the two sides of the head 3G, g has set _ pair of igniters 33Α At present, the fifth-grade ignition kits 33A and 33B are connected to the ignition inspection 33a and 33b respectively through a wire not shown, and the ignition plugs 33a and 33b are discharged at high voltage to ignite the gas burners 24A and 24B. The gas burners 24A, 24B suction ports 24AK, 24BK are in control In the vicinity of the box-making 3G, the switch board 34, and the mounting bracket 35, the air is sucked by the intake air Π24AK, 24KB during the combustion, and an air flow can be generated in the vicinity of this area, and the aforementioned control box can be cooled. As shown in FIGS. 3 to 7, the switch substrate 34 ′ is mounted on the lower surface of the panel 22 at a position corresponding to the operation sections 40A to 40G described later, and is disposed above the control panel 3G. Therefore, the mounting bracket 35 is fixed by using an adhesive 36 formed of a stone rubber, and the mounting board 13 1232921 is used to mount the switch substrate 34 with a plurality of screws 37. The aforementioned mounting bracket 35 is a bottomless box having a top panel 35T, and the top panel 35T is a non-point contact switch 38A to 38G and a corresponding indicator light 39A to 39C, which are described as a detection device arranged behind the switch substrate 34 35K is formed in the part. 5 Among the aforementioned openings 35K, the opening 35K for the non-point contact switches 38A to 38G has a peripheral wall 35S, and when the switch substrate 34 is mounted on the mounting frame 35, the non-point contact switches 38A to 38G surround the side with the peripheral wall 35S. Square, and the top part is opposite to the operation part of the panel 22 via the opening 35K (to be described later). A plurality of 10 non-touch switches 38A to 38G are arranged on the front edge of the upper portion of the above-mentioned switching substrate 34 at a lateral interval. That is, a power switch 38A is disposed in the center of the leading edge of the switching substrate 34, and on both sides of the power switch 38A, there are arranged point-to-point flameout switches 38B and 38C for implementing ignition and flameout of each gas burner 24A and 24B. . On each side of the flameout switches 38B and 38C at each point, a pair of fire power-enhancing 15 switches 38D and 38E and fire power-reducing switches 38F and 38G for adjusting the fire power of the gas burners 24A and 24B are arranged. In this embodiment, since the "Serin glass" is used, it is difficult to see the inside of the furnace due to the dark color. In addition, because it has infrared transmittance, no special treatment is required for the glass. However, as long as the glass inside the furnace can be seen, printing is carried out inside the glass. At this time, it can be colored to have a specific light transmittance, so that 20 can be fully The part of the panel 22 corresponding to the aforementioned switches 38A to 38G is transmitted through infrared rays. Alternatively, it may be transparent without being colored in a specific color. Each of the switches 38A to 38G described above uses light-sensing elements including a light-emitting element 38a as a light-emitting portion that generates infrared rays and a light-receiving element 38b as a light-receiving portion that receives infrared rays. In addition, the panel 22 corresponding to the switches 38A to 38G can be colored with 14 1232921 to form a specific color to transmit visible light or transparent, and each of the switches 3 8A to 3 8G can use a light sensor with a visible light element and a light receiving element. Device 'to replace the composition. In addition, each of the switches 38A to 38G can be an electrostatic capacitance type switch that operates by a change in the electrostatic capacitance on the panel 22, and the constitution can be replaced by 5 times. When this electrostatic capacity switch is used, it is not necessary to color the part corresponding to the switch of the panel 22 to a specific color or make it transparent. A plurality of display lamps 39A to 39C including light emitting diodes and the like are arranged on the switch substrate 34 so as to correspond to the respective switches 38A to 38G. That is, a power display lamp 39A is arranged near the rear of the power switch 38A for displaying the power-on state by lighting. Near one side of the fire switch 38B, the fire boost switch 38D, and the fire reduction switch 38F used for one of the gas burners 24A, five fire power display lamps 39B are arranged horizontally for displaying the fire power adjustment state (strong and weak state) by lighting. At the point of the other gas burner 24B, the flameout switch 38C, the fire power increase switch 38E and the fire power reduction switch 38G are located near the side 15. There are five fire power display lights 39C in the horizontal direction. . In addition, as a matter of course, the display portions corresponding to the respective display lights 39A to 39C of the panel 22 are formed so that the display light can be transmitted. As shown in FIG. 7, the aforementioned opening 35K ′ is formed in the mounting bracket 35 to correspond to each of the switches 38A to 38G of the uranium and the respective display lamps 39 to 39 (). The firepower display lamps 39A to 39C are connected via The opening 35K is connected to the inside of the panel 22, and the switch substrate 34 is mounted on the mounting bracket 35. The silicone rubber constituting the adhesive 39 is transparent and interposed between the entire switch substrate 34 including the opening 35κ portion and the switch substrate 34. Between the panels 22, the light from 3% of the aforementioned light-emitting elements or the display lamps 39A to 39C will not be irregularly reflected under the panel 22. 15 1232921 As shown in Fig. 1, Fig. 5, and Fig. 7, it indicates operation The display of the sections 40A to Confucius is attached to the panel 22 by printing or coloring, and is located directly above the switches 38A to 38G. The operation sections 40A to 40G are arranged in the gas-burning state 24A, 24B. The position that is truly offset to the side, and in this embodiment, the placement position is in front of the middle of the two gas burners 24 A, 24B. Moreover, the operator selectively contacts and operates these operation sections 4 〇A ~ 4〇g 牯 In the corresponding switches 38A ~ 38G, borrow from The infrared reflection of the light element 38a is sensed by the light receiving element 38b to detect the operating state of the operator. In addition, a pair of 10 are attached to the panel 22 by printing or coloring, and are located on both sides of the foregoing firepower display lamps 39B and 39C. The upper firepower display symbols 41A to 41D. In addition, according to the lighting display positions of the firepower display lamps 39B and 39C between a pair of firepower display symbols 41 to 4id, the adjustment status of the firepower can be confirmed. In addition, in Fig. 7, although For easy understanding, the thicknesses of the operation parts 40a to 40G are shown, but the thickness of the operation parts 40A to 40G does not actually exist. 15 Next, the circuit configuration of the gas furnace described above will be described with reference to FIGS. 8 and 9. And the operation. The flowchart shown in FIG. 9 is the controller of the control device 31 based on the program data in the memory 32. In the flowchart of the embodiment different from the embodiment shown in FIG. The same applies to the control device 31 of the gas furnace, and a DC power source 59, 20 is connected, and an AC power source 60 for actuating the valves 28, 29A, 29B and the ignition 33A, 33B is connected. When the operator touches the operation part 40A, and the power switch 38A detects the operation state, the control device 31 turns on the power indicator 39A. Then, when the operator touches the operation part 40B and 40C, the ignition switch 38B is turned on. When the 38C and 38C detect their operating conditions, the control device 31 is used to open the valves 16 1232921 28, 29A, and 29, and the igniters 33A and 33β are activated to make the gas burners 24A and 24B ignitable. At this time, the control device 31 may constitute a malfunction. The prevention device, the switches 38 to 38G, detects that there is a foreign object or a small animal on the panel 22 other than the operator, and the control device 31 does not malfunction. That is, in the formula shown in Fig. 9, it can be judged whether the power switch 38A is operated continuously for two seconds alone (step S1), and the AC power supply 60 is not applied when it cannot be operated continuously for more than two seconds. Further, if the AC power source 60 is applied by continuously operating the power switch 38A for more than two seconds, it can be determined whether or not the point flameout switches 38B and 38c are operated (step S2). In this determination, when the ignition switch 38B, 38C cannot be operated, it is determined whether 15 seconds have passed since the operation of the power switch 38A (step S3). When the power switch 38A has been operated for more than 15 seconds, the AC power source 60 is turned off and returns to the initial state. On the other hand, when the power switches 15 to 38A are operated and the point-of-open switches 38B and 38C are operated within 15 seconds, an ignition operation is performed (step S4). Therefore, when foreign matter such as paper or cloth is placed on the operation sections 40A to 40G of the panel 22, and the power switch 38A and the flameout switches 38B and 38C are simultaneously operated or only the power switch 38A is continuously operated, there is no control. 20 Device 31 outputs the ignition operation signal to the cases of valves 28, 29A, 29B and igniters 33 A, 33B. In addition, even if small animals such as cockroaches or mice are moved on the operating sections 40A to 40G of the panel 22, the power switch 38A is operated only for a short time, and the ignition signal is not output from the control device 31. Therefore, it is possible to prevent the gas burner 2 from being ignited by a small amount due to foreign objects or small movements on the panel 22 detected by the switches 38A to 38G, other than the operator. In addition, when the gas burners 24A and 24B are ignited, for example, regardless of the intensity of the firepower when the flame is turned off, the firepower adjustment patterns generated by the gas volume adjustment 29, 2 and 2 are in multiple stages (such as the five stages). ), It is set to the state of 5 adjustments (for example, 3 of the 5th stage 3), as the Shida gas i at the time of ignition. Therefore, when it is necessary to change the firepower, as long as the firepower increase switches 38D, 38E or the firepower reduction switches 38F, 38G are operated, the gas amount adjustment valves 29A and 29B are actuated by the control device 31 to enhance the adjustment of the firepower from the intermediate adjustment state or Weak adjustment. 10 On this day, the action control device is constituted by the description control device 31, and even if the operator uses the operation section 40D and the continuous operation switch 38D 38E to enhance the firepower, the firepower enhanced control corresponding to the continuous operation is not performed. action. That is, the aforementioned fire power enhancement switches 38D, 38E change the fire power in each direction of the enhancement by each operation, and even if the operation is continued, the control 15 clothing setting 31 does not connect to it, limiting the sharp enhancement of the fire power. action. Therefore, with regard to the .Hai fire power enhancement switch 38o, MEE, it becomes only a phase operation effective firepower-. In addition, when the firepower reduction switch is switched on, the muscle is continuously operated, and its operation can be effectively controlled by the control device 31 to reduce firepower. In addition, after the ignition of the helium gas burners 24A and 24B, an emergency flameout device is constituted by the aforementioned clothing control unit 31. When the operator misunderstands the operation, the flameout action can be implemented. In other words, in the ignition state of the gas burners 24A and 24B, the operation sections 40A ~ 4G are the same as those of the M (two or more) operating units, that is, the switches 38A, 38G4, and the control device are broken for abnormal operation. And close the valves 28, 29A, 29B 'to extinguish the gas burners 24A, 24B. In addition, in the ignition state of the gas 18 1232921 and the ignition points 24A and 24B, and when the point flameout switches% ^, 38C and other switches 38D to 38G are operated at the same time, the control device 31 preferentially operates the point flame switches 38B and 38C to extinguish gas combustion.器 24A, mb. Of course, in the ignition state of gas combustion H24A, 24B, when the point flameout switch 5 38B, 38C is operated separately, gas combustion 24A, 24B can be extinguished. Therefore, according to this embodiment, the following effects can be obtained. In this gas furnace, non-point contact switches 38A to 38G are provided under the panel 22, and various operations such as ignition or fire power adjustment are performed on the upper position of the panel 22 made of heat-resistant glass. In addition, when the switches 38A to 38 detect the operation of the operator, a control device 31 is provided to control the operation of the operation in accordance with the operation. No accompanying operation knob is generated. Therefore, there is no need to highlight the configuration on the panel 22 to perform operations such as ignition or power adjustment.

Therefore, the switches 38A to 38G can be disposed separately from the gas burners 24A and 24B, and it is possible to surely prevent the heat during heating and cooking from affecting the switches 38A to 38G. In addition, the operating sections 40a to 40G are not on the true faces of the gas burners 24A and 24B, and can be arranged to the left or right, and can easily and accurately perform operations such as ignition or firepower adjustment. In addition, when the boiling pot and the like are not contaminated by the spilled cooking juice and the like when they fall away from the fire rack, it is difficult for the switch to deteriorate. (3) In the gas furnace, a portion corresponding to 10 of the switches 38A to 38G of the aforementioned panel 22 is formed to be transparent to infrared rays. The switches 38A to 38G use a light sensor having an infrared light emitting element 38a and a light receiving element 38b. Therefore, according to the change of the reflected light of infrared rays, the operator's operation can be correctly detected, and specific actions such as ignition or firepower adjustment can be performed in accordance with the operation. Furthermore, in addition to the aforementioned configuration, the switches 38A to 38G can also detect and operate correctly when a light sensor with a visible light emitting element and a light receiving element is used, or a capacitance type switch that operates by the change in capacitance is used. Person's operation. (4) In this gas furnace, the thermal conductivity of the aforementioned panel 22 is set in the range of ο ~ 2.0 watts / m · k. Therefore, the heat of the gas burners 24A and 24B during heating and cooking can be transmitted to the switches 38A to 38G through the panel 22, and the heat can be prevented from affecting the switches 38A to 38G. Therefore, it is possible to prevent the overheating of the switches 38A to 38G from malfunctioning, and prevent the heating of the operation portion 40A to 40G and the uncomfortable degree of the medium, thereby enabling comfortable operation. (5) In the gas furnace, when the switches 38A to 3gG detect 20 1232921 foreign objects or small animals on the panel 22, the control device 31 can be prevented from malfunctioning. Therefore, when a foreign matter such as paper or cloth is placed on the upper panel 22 of the switch 38A to the upper side, or when a small animal such as a mouse passes by, it is possible to surely prevent an accidental ignition operation. 5 ⑹ In this gas furnace, the operator can restrict the operation of the control device 31 when the operator makes a mistake. Therefore, even if an operator mistakenly performs an operation for enhancing the firepower, it is possible to surely limit the execution of the firepower for the wrong operation. (2) In this gas stove towel, after the aforementioned gas burning and firing 10, the operator can perform a flameout operation when the operator makes a mistake. Therefore, after the gas combustion ^ §24A, 24B is ignited, the operator can directly extinguish the gas burners 24A and 24B, for example, when a plurality of switches 38A to 38G are operated at the same time, thereby preventing cooking errors. Next, the second embodiment of the present invention will be described with reference to Fig. 10 and Fig. 11 by focusing on the parts 15 different from the first embodiment. In addition, in the description of each embodiment after the second embodiment, as in the second embodiment, only the parts different from the first embodiment will be mainly described. As shown in FIG. 10, in the second embodiment, only the flameout switches 43A and 43B of the flameout function are provided on the switch substrate 34, instead of the point flameout switches 38B and 38C of the aforementioned 120th embodiment. Further, on the top face of the panel 22, operation portions 44A and 44B located above the flameout switches 43A and 43B are attached by printing or coloring. Further, in the second embodiment, after the power switch 38A is operated, the fire power-enhancing switches 38D and 38E and the fire-killing switches 38F and 21 of the respective gas burners 24A and 24B and the operation unit 40D are simultaneously operated. 1232921 38G, can perform ignition action. Further, 'this second embodiment is also similar to the first embodiment described above, and constitutes a decisive action preventing device for detecting a foreign object or a small animal detected by the control device 31 by using MP. That is, as shown in FIG. Η, after determining whether the 5 power switch 38A is operated independently for two consecutive seconds (step S5), it is determined whether to simultaneously #make the fire power increase switches 38D, 3 and the fire power reduction switches 38F, 38G ( Step S6). In this determination, when the switches 38D to 38G are not operated simultaneously, it can be determined whether or not 15 seconds have elapsed by the operation of the power switch 35A (step S7). On the other hand, when the power switch 38A is operated for more than 15 seconds, the AC power supply is cut off and returned to the initial state. In contrast, the switches 380 to 38 can be operated simultaneously within 15 seconds of the operation of the power switch 38A (at 3 o'clock, an ignition operation can be performed (step S8). Therefore, the second embodiment can also be obtained and described in the foregoing. The effects of the first embodiment and the fifteenth embodiment (1) to (7) are the same. The third embodiment continues with the description of the third embodiment of the present invention according to FIG. 12. In the third embodiment, each gas is burned. The power switches 38A, 24A, 24B, and separate power switches 38A are disposed on both sides of the upper surface of the switch substrate 34. 20 On the panel 22, operation portions 40a above the power switches 38A are attached by printing or coloring, respectively. Moreover, this embodiment can also perform the same ignition operation as the operation shown in the first embodiment shown in Fig. 9. Therefore, the third embodiment can also obtain the same as described in the first embodiment (1) to ( The same effect is obtained. 22 1232921 Fourth Embodiment Next, a fourth embodiment of the present invention will be described with reference to FIG. 13. In this fourth embodiment, a frame 22b on the front edge side of the panel 22 is disposed. By light emitting elements such as infrared An operator detection sensor 45 formed by 45a and a light receiving element 45b. The operator detection sensor 45 can detect the presence of the operator on the front side of the fluid table 23 and detect only the presence of the operator. The operation corresponding to the operation of the switches 38A to 38G can be allowed. Therefore, according to the fourth embodiment, in addition to the effects described in the first embodiment (1) to (7), the following effects can be obtained. 10 (8) In this gas furnace, because there is no operator detection sensor 45 to detect the presence of the operator, the switches 38A to 38G can be more surely prevented from misdetecting foreign objects or small animals on the panel 22 and performing misoperations such as ignition. In other words, in this fourth embodiment, when the operator is not detected by the operator detection sensor 45, it is possible to set an operation that cannot be performed for ignition or enhanced firepower. 15 Fifth Embodiment Next, according to FIG. 14 and FIG. FIG. 15 illustrates a fifth embodiment of the present invention. As shown in FIG. 14, in this fifth embodiment, a power switch 38A is disposed on one side of the switch substrate 34, and a 20 or With An operation portion 40A corresponding to the power switch 38A is attached. An operation lock switch 46 as a locking device is provided on the other side of the switch substrate 34 at a position away from the power switch 38A, and on the panel 22 An operation portion 47 corresponding to the operation lock switch 46 is attached by printing or coloring. In addition, when the operation panel is opened on the cleaning panel 22 or the like, the operation lock switch 23 1232921 is closed 46, and then the power switch MA can be operated by operating the power switch MA. If the setting switch 38 is eight or more, it cannot be operated. That is, as shown in FIG. 15, it is determined whether the operation lock switch 46 is continuously operated for two seconds (the steps are still). When the operation is continuously performed for more than two seconds, the power is determined. Whether the switch 38A is operated (step s0). 5 In this determination, when the power switch 38A fails to operate, it can be determined whether the operation of the lock switch 46 has passed for three seconds (steps. Also, when the operation of the lock switch 46 has passed for three seconds or more, Return to the initial state. In this regard, when the power switch 38A can be operated within three seconds of the operation of the self-locking switch 46, it can be set to an inoperable state (step S12). 10 'and clean the panel in this state When it is above 22, even if it touches the operation part ~ preparation of each switch 38A ~ 38G, there is no mistake in detecting those operating when W8A ~ 38G is turned on, which can prevent accidental ignition operation, etc. When not in use, it is set to the aforementioned inoperable state to prevent malfunction caused by foreign objects or small animals.

Set to fire power cannot be adjusted. Therefore, in this setting state, it is possible to surely prevent the inadvertent adjustment of the firepower due to an erroneous operation or the like. 20 ® According to the fifth embodiment, in addition to the effects described in the aforementioned first application modes (1) to (7), the following effects can be obtained. (9) In this gas furnace, the operation of the control device 31 can be locked as required. Therefore, for example, when the upper surface of the panel 22 is cleaned, it is possible to surely prevent operations such as ignition from being erroneously performed due to erroneous detection of the switches 38A to 38G. 24 1232921 Sixth Embodiment Next, a sixth embodiment of the present invention will be described with reference to Fig. 16. In this sixth embodiment, each of the five thermal power adjustment switches 48A to 48B is disposed on the switching substrate 34, instead of the thermal power increase switches 38D and 38E and the thermal power reduction switches 38F and 38G of the first embodiment. The panel 22 is printed or colored with five operation sections 49A and 49B corresponding to the thermal power adjustment switches 48A and 48B. Furthermore, by selectively operating the fire power adjustment switches 48A and 48B, the fire power of the gas burners 24A and 24B can be adjusted in five stages. In this way, since the switches 48A and 48B corresponding to the fire power of each stage are provided, it is easy to understand the fire power adjustment operation. It is easy to operate and prevents misoperation. Therefore, in this sixth embodiment, the same effects as those described in the first embodiment (1) to (7) can be obtained. In addition, this embodiment can be modified as follows to make it concrete. 15 As shown in Fig. 17, a positioning notch portion 50 is formed at the inner end of the frame 22b on the front edge side of the panel 22, and a mounting bracket 35 of the switch substrate 34 is fitted into the notch portion 50. With this configuration, the switch substrate 34 can be positioned at a predetermined mounting position under the panel 22. Therefore, the switches 38A to 38G provided on the switch substrate 34 can be accurately aligned with the operation portions 40A to 2040G provided on the upper surface of the panel 22. In addition, since the switching substrate 34 can be located away from the burner and placed close to the operator, the thermal influence from the burner can be further reduced, and the operation can be easily performed. In each of the embodiments described above, the gas burner 24A, 24B burns the daylight, and its firepower adjustment state is stored in the memory 32. Then, the gas burners 24A, 24B accidentally turn off due to the overflow of boiling water, etc. At this time, when it is ignited by the ignition operation following 25 1232921, it can return to the previous fire power adjustment state. In this way, the heat needs to choose unintended firepower, and it can simply return to the state before the fire. In the operation of each embodiment, the setting can be arbitrarily changed. The number of seconds in which the power switch 38A is continuously operated, and the number of seconds elapsed from the operation of the power switch and the like to the operation of the flameout switches 38B and 38C. In each of the embodiments described above, there is a function of arbitrarily setting the number of seconds for connecting and operating the power switch 38A and the like, from the operation of the power switch 38A and the like to the operation of the ignition switch 38B, 38C, and the like. In this way, it is possible to obtain an operation pattern according to the operator's condition or desire. In each embodiment described above, the number of the gas burners 24A and 24B can be 5 and the number of Ai can be one or two or more, and the switches 38 and 38G and the operation section 40A and can be changed accordingly. 40G number. In each of the implementation forms described above, a plurality of 15 building feet can be protruded below the main body box 21, and a gas furnace can be set on a fluid counter top. Each of the gas furnaces of the foregoing embodiments is provided with a notification device for notifying the gas furnace by a buzzer or the like when the gas furnace is mishandled. Each of the gas furnaces of the foregoing embodiments is provided with a voice sound generating device, and voices such as operation confirmation or the state of the gas furnace (for example, 20 firepower) are issued to the operator by a living sound. The aforementioned gas furnace has a sound recognition function and an operation function generated thereby ', and the operator can perform actions such as fire power enhancement or fire-firing to the gas furnace by sound. EFFECTS OF THE INVENTION 26 1232921 and above, as exemplified in the embodiment, in the present invention, the following effects can be exhibited. That is, regardless of problems such as deterioration of operability caused by deformation of the operation knob, etc., operability during heating and cooking can be improved, and the work can be performed smoothly and surely when the upper surface of the panel is cleaned. Moreover, since there are no protrusions on the panel, the panel can be widely used, and the usability is improved. In addition, since it is not necessary to form the through shaft L for the operating shaft on the panel, it is possible to prevent the overflowing boiling juice from entering through the through hole, which may cause the failure of the built-in parts. Furthermore, since it becomes unnecessary to use a member such as a heat shield without participating in cooking, the configuration becomes simple, and the gas stove can be easily assembled. 10 [Brief description of the drawings] Fig. 1 is a plan view showing the gas furnace of the first embodiment.
