Field of the Invention The present invention relates to a stove having a heating mechanism, and particularly to a device having an operation portion for indicating the operation of the heating mechanism on the top surface of the top plate. Stove. BACKGROUND OF THE INVENTION It is known that, as shown in Fig. 6, in a built-in stove in which a cooktop body 101 is buried in a predetermined opening on a countertop of a system kitchen, a gas burner 100a, 100b is accommodated in the cover. The glass top plate 102 on the upper surface of the oven body 101 is provided with operation buttons 10a and 103b for performing ignition/extinction and firepower adjustment of the gas burners 1a, 100b (see, for example, Patent Document 1). According to the above-mentioned furnace, it is not necessary to provide an opening for facing the operation portion on the front surface of the table as in the case of the furnace having the operation portion on the front surface, and the setting of the furnace on the table surface can be easily performed. Further, since the ignition/fire or the fire power adjustment of the gas burner can be performed by the operation buttons 10a, 103b provided on the top plate 102 and having excellent visibility, the operability of the user can be improved. [Patent Document 1] JP-A-58-186302, JP, JP-A-Mon. 1 Disclosure of the Invention Problem to be Solved by the Invention However, by the stove shown in Fig. 6, the operation is 103a, 1275748 103b. It is configured to protrude above the glass top plate 1〇2, so it may be hindered during conditioning. Therefore, it is generally considered that the operating mechanism of the gas burners 100a, 10〇b may be formed inside the glass top plate 102 such as a static capacitor. The detecting portion of the sensor has a touch switch 5 of the operation portion on the surface of the glass top plate 1〇2, and the upper surface of the glass top plate 102 is formed into a flat surface. In order to increase or decrease the firepower of the gas burners l〇〇a, l〇〇b in a plurality of sections, a firepower rise switch for indicating an increase in firepower and a firepower for indicating a decrease in firepower are provided for each burner. The down switch allows the user to easily change the firepower of each burner by touching the up switch and the down switch. 10 However, when the fire-rising switch is formed as a touch switch and is placed on the glass top plate 102, in the heating conditioning, the cooking material due to the conditioning material from the steel placed on the fire holders 104a, 104b may sometimes occur. Or the falling device on the glass top plate 1〇2 covers the fire rise switch, and the fire rise switch is switched from the closed state to the open state. 15, for example, when the right burner 100b is used for heating conditioning, the firepower rise switch of the right burner 1〇〇1) is switched from the off state to the on state due to factors other than the operation of the user. The process of increasing the heating power of the right burner 100b is also performed. Further, at this time, there is a problem that the heating power of the right burner 100b increases in accordance with the intention of the user, and the conditioning material 20 is excessively heated to cause the conditioning failure. Accordingly, it is an object of the present invention to solve the aforementioned problems and to provide a cookware which can prevent the conditioning material from being overheated against the intention of the user. Means for Solving the Problems The present invention has been accomplished to achieve the foregoing objects, and relates to a -1275748 stove comprising a structure of a furnace body, a cover storable heating machine 5 10 15 20 mechanism The top plate of the work is arranged such that the user can indicate the contact or proximity mechanism of the heater and is detected on the top plate, and the front mechanism is changed by the plural section set by the county. 'Addition of the heating amount of the heating structure is added (4) Ascending gate heating machine inspection, #_", 幵 switch is switched from non-detection state to twisting II/, and the heating is performed by the aforementioned heating amount changing mechanism The heating element of the mechanism is increased by one. The second structure is that the heating control mechanism is changed to the heating device, and the heating amount rising switch is cut from the non-detecting state until the state is inspected, and the state is maintained. The heating amount of the heating mechanism is reduced by the amount of the above-described adjustment means. According to the present invention, the heating control mechanism is switched from the non-detection state to the detection state. When the above-mentioned addition: two m heating amount ± liter switch is maintained in the double-measurement mode, the heating amount of the heating mechanism is reduced by one section. Therefore, even if the conditioning material rises due to the cooking material or the like, the heating amount is increased from the non-detection. When the state is switched to the detection state, and then the heating amount increase switch is maintained in the detection state, the heating amount of the heating mechanism is also returned to the heating amount when the heating amount increase switch is in the non-detection state, and the foregoing does not continue. The state of heating of the heating mechanism is increased. ^ ^ ▲ Eight, hunting this, the conditioning is overheated against the user's mind. Also 'characterized to include a heating amount display mechanism, and talk about heating 7 1275748 quantity The heating amount of the display mechanism in the heating mechanism is the above-mentioned plural number (four) heating

物之加熱，則調理物會違背使用者之心意而被過量地加熱 且調理失敗。於右燃燒器4b之燃燒中，因使用者之操作以 外之因素使右燃燒器4b用之火力上昇開關13b自關閉狀態 切換至開啟狀態時亦相同。 故，於控制器30所具有之加熱控制機構31係依此於左 10 燃燒器4a之燃燒中，在因使用者之操作以外之因素使左燃 燒器用之火力上昇開關13a自關閉狀態切換至開啟狀態 時，進行用以防止繼續左燃燒器4a之燃燒量增加之狀態的 處理。又，同樣地，加熱控制機構31係於右燃燒器4b之燃 燒中，在右燃燒器用之火力上昇開關13b自關閉狀態切換至 15 開啟狀態時，進行用以防止繼續右燃燒器4b之燃燒量增加 之狀態的處理。 以下，依據第4至5圖之流程圖，說明包含該等處理之 利用加熱控制機構31之燃燒器火力之增減處理。另，第4至 5圖之流程圖係對左燃燒器4a之處理，然而，對右燃燒器4b 20 之處理亦相同。 加熱控制機構31係於左燃燒器4a為燃燒中時反覆實行 第4圖之步驟1至第5圖之步驟4之環路。又，於步驟1中，若 點火準備開關11a構成開啟狀態時，則分岔至步驟10，且加 熱控制機構31會將左燃燒器用開關閥41a閉閥且使左燃燒 13 1275748 器4a媳火。 又’步驟11至步驟12係利用亮燈控制機構32之處理， 且亮燈控制機構32係於步驟11中使點火準備顯示部14a熄 燈’並於步驟12中使火力位準顯示部15a熄燈，同時於步驟 5 13中使蜂鳴器18鳴動，並告知使用者左燃燒器4a之熄火。 其次，於步驟2中，若火力下降開關12a構成開啟狀態 時’則分岔至步驟20。步驟20至步驟22係使左燃燒器4a之 火力減少一段之處理，且亮燈控制機構32係於步驟20中使 蜂鳴器18鳴動，並於步驟21中使火力位準顯示部15a之棒顯 10 示朝負一段方向（第2圖中為左方向）減少，並告知使用者左 燃燒器4a之火力之減少。又，於接著之步驟22中，加熱控 制機構31係將左燃燒器用火力調節閥42a之開度縮小一 段，且使左燃燒器4a之火力減少一段。 於接著之步驟23中，若火力下降開關12a返回至關閉狀 15態時，則前進至第5圖之步驟3，若火力下降開關12a仍為開 啟狀態時’則分岔至步驟30。又，於步驟30中，若火力下 降開關12a構成在預定時間（例如1秒）以上連續地維持於開 啟狀態之「連續開啟狀態」時，則前進至步驟31。步驟3〇 至步驟33係與前述步驟20至步驟22相同之處理，且左燃燒 20 器4a之火力減少一段。 又，自步驟33返回至步驟23,且火力下降開關12a為「連 續開啟狀態」時，則自步驟30前進至步驟31，且反覆實行 步驟31至步驟33之處理。故，使用者可藉由持續碰觸火力 下降開關12a且使火力下降開關12a維持於開啟狀態，而將 14 (8： 1275748 左燃燒器4a之火力連續且迅速地降低至最小位準（位準1)。 其次，於第5圖之步驟3中，若火力上昇開關na構成開 啟狀態時，則分岔至步驟40。又，亮燈控制機構32係於步 驟40中使蜂鳴器18鳴動，且於步驟42中使火力位準顯示部 5 15a之棒顯示朝正一段方向（第2圖中為右方向）增加，並告知 使用者左燃燒器4a之火力之增加。又，於接著之步驟41中， 加熱控制機構31係將左燃燒器用火力調節閥42a之開度增 加一段，且使左燃燒器4a之火力增加一段。 又，於接著之步驟43中，若火力上昇開關13a返回至關 10 閉狀態時，則前進至步驟4，若火力上昇開關13a仍為開啟 狀態時，則分岔至步驟50。於步驟50中，若火力上昇開關 13a為「連續開啟狀態」時，則前進至步驟51。 步驟51至步驟53係與前述步驟20至步驟22相同之處 理，且左燃燒器4a之火力減少一段。又，於步驟54中等待 15 火力上昇開關13a構成關閉狀態後，前進至步驟4，藉此， 於火力上昇開關13a構成「連續開啟狀態」時，在步驟42中 一度增加一段之左燃燒器4a之火力會於步驟53中減少一段 並復原。 在此，於因煮溢物等而覆蓋操作部6，且因使用者之操 20作以外之因素使火力上昇開關13a自關閉狀態切換至開啟 狀態時，係假想火力上昇開關13a之後亦有某程度之時間維 持於開啟狀態，故，此時係構成「連續開啟狀態」，且自步 驟30前進至步驟31，同時於步驟33中，左燃燒器4a之火力 會減少一段。 15 1275748 藉此，左燃燒器4a之火力會維持於火力上昇開關13a因 煮溢物等而自關閉狀態切換至開啟狀態前之狀態，故，於 因煮溢物等而覆蓋操作部6且火力上昇開關13a自關閉狀態 切換至開啟狀態時，可防止維持於左燃燒器4a之火力增加 5 之狀態且調理物被過量加熱之狀況。 另一方面，使用者欲增加左燃燒器4a之火力時，只要 用手指碰觸左燃燒器用之火力上昇開關13a且在構成「連續 開啟狀態」前放開手指即可，藉此，自第5圖之步驟43前進 至步驟4，且維持步驟42中左燃燒器4a之火力增加一段之狀 10 態。 其次，若於步驟4中檢測出左燃燒器4a之熄火等異常 時’則分岔至步驟60，且亮燈控制機構32係於步驟6〇中使 蜂鳴器18鳴動，並於步驟61中使點火準備顯示部14a忽亮忽 1滅，且告知使用者產生異常。又，亮燈控制機構32係於接 5著之步驟62中使火力位準顯示部15a熄燈。又，於接著之步 驟63中，加熱控制機構31係使左燃燒器用開關閥41a閉閥， 阻斷對左燃燒器4a之燃料氣供給，並前進至步驟64且構

The firepower lowering switch i2a (corresponding to the heating amount drop 10 switch of the present invention) and the fire power rising switch 13a (corresponding to the heating amount rising switch of the present invention) in 5 stages (level 1 to level 5); 4a is in the ignition ready state The ignition preparation display portion 14a of the left burner is used to display the fire level display portion 15a of the left burner, and the fire level display portion 15a (corresponding to the heating amount display mechanism of the present invention). When the left burner 4a is in the ignition preparation state, if the fire power rise switch 13a is operated, the ignition process of the left burner 4a is performed. Further, when the ignition preparation switch mountain or the operation switch _ is operated in the combustion of the left burner 4a, The flameout process of the left burner 4a is performed. Similarly, in order to instruct the operation of the right burner 4b, an ignition preparation switch nb for setting the right burner 4b to the ignition preparation state is provided; for switching the right combustion power to 5 The segment (the thermal power drop switch of the level i to the level ^ is equivalent to the heating amount reduction switch of the present invention) and the fire rise switch (corresponding to the heating amount (10) of the present invention); when the right weave (four) is in the ignition preparation state And the right burner 4b, the ignition preparation of the mountain light is 9 975748. The display portion 14b; and the fire level display portion 15b for displaying the firepower setting of the right job H4b (corresponding to the present invention) The heat display mechanism). In addition, when the right burner 4b is in the ignition preparation state, if the operation heat is on the _M13b' material, the ignition process of the right money H4b is performed. X, the ignition preparation is operated in the combustion of the right combustion/5 burner 4b. When the switch or the operation switch is operated, the flame extinguishing process of the right burner 4b is performed. Further, the operation unit 6 includes the unlocking display unit 16 and is illuminated when the "operating state" is located; When the continuous operation is performed for a predetermined period of time (for example, 4 seconds) or more, and the so-called child lock state in which all the operations of the switch 10 cannot be performed, the light is turned on. Here, the respective opening relationships of the operation portion 6 are set on the glass top plate. The static capacitance sensor inside the 2 is formed with the printed portion printed on the surface of the glass top plate 2 facing the electrostatic capacitance sensor and showing the contact point of each switch = contactless contact switch. Moreover, when the electrostatic body is placed on the printed portion (the surface portion of the glass top plate 2 facing the electrostatic capacitance sensing), the electrostatic body can be detected by the electrostatic capacitance sensor, and the touch switch is turned on. State (corresponding to the detection state of the present invention) 'On the other hand, when the electrostatic body is not placed on the printed portion, the electrostatic body cannot be detected by the electrostatic capacitance sensor, and the touch switch constitutes an off state (equivalent In the surface measurement state of the present invention). Each of the display portions of the 2' X' operating portion 6 is constituted by an LED provided on the inside of the glass top plate 2 and a printing blade printed on a surface portion of the glass top plate 2 facing the LED. Further, when the LED is turned on, the display unit is configured to be illuminated, and when the LED is turned off, the display unit is turned off. Further, the fire level display unit 15a displays the fire level of the left burner 4a by displaying the number of lightings of the lighting portion from the left side by a bar composed of the five lighting portions 10 1275748. For example, the left burner, for example, when the fire level is 1 , only the left part of the shaft * is left, and when the fire level of the left burner 4a is 5, the stick is displayed brightly. Similarly, the lamp m ❹ k indicates that the power level display unit displays the fire level of the right burner 4b by using the bar composed of the light-emitting portions shown in the figure to display the number of lightings from the left side of the lighting portion ( Level 1 to level 5). Next, referring to Fig. 3, a controller 30 for controlling the operation of the entire stove is provided in the stove main body 1, and each switch of the operation unit 6 (the operation switch 10 10, the ignition preparation switch 11a, Ub, and the firepower lowering switch) The detection signals of the operating states (on/off) of the 仏, (3), and the fire rise switches 13a, 13b) are input to the controller 30. Further, according to the control signal outputted from the controller 30, the gas main valve 4 for switching the supply and the blocking of the fuel gas to the furnace body 1 is controlled, and the fuel gas supply for switching the 15 pairs of the left burner 4a is controlled. The left burner switch port 41a for blocking, the left burner heat regulating valve 42a (corresponding to the heating amount changing mechanism of the present invention) for changing the supply flow rate of the fuel gas to the left burner, and the left burner 4a The ignition electrode (not shown) applies a high voltage to generate a spark discharge to the left burner igniter 43a, and a right burner switching valve 41b for switching the supply and blocking of the fuel 20 to the right burner 4b. The right burner for the fuel gas of the right burner 4b is supplied to the right burner for the fire regulating valve 4 (corresponding to the heating amount changing mechanism of the present invention), and the ignition electrode (not shown) of the right burner 4b is applied with a high voltage to generate a spark. The right burner of the discharge is actuated by the igniter 43b. 11 1275748 Further, each display unit (ignition preparation display units 14a and 14b, fire level display units 15a and 15b, unlock display unit 16 and lock) included in the operation unit 6 is controlled based on a control signal output from the controller 30. The display unit 17) is turned on/off and the buzzer 18 is turned on/off. Further, the controller 30 includes a heating control mechanism 31 for controlling the actuators of the left burner 4a and the right burner 4b, and a lighting control mechanism 32 for performing each of the remaining units 6 The control panel of the bright light/xenon lamp uses the informer of the buzzer 18. Here, when the left burner 4a is in the middle of combustion, if the user touches the thermal power rise switch 13a for the left combustion burner and the thermal power rise switch i3a is switched from the closed state to the open state, the heating control mechanism 31 performs the operation. The process of increasing the heating power of the left burner 4a, similarly, when the right burner 4b is in the combustion state, if the user touches the firepower rising switch 13b for the right burner and the firepower rising switch 13b is switched from the closed state to the open state Then, the heating control mechanism 31 15 performs a process of increasing the heating power of the right burner 4b. However, as described above, each of the touch-opening relationships provided in the operation unit 6 detects the presence or absence of an electrostatic body existing on the glass top plate 2, and therefore, the user touches the touch switch with a finger, as in the first ( b) As shown in the figure, when the left burner 4a is used to heat the conditioner in the pot 20, a spray 20 of the conditioner is generated and the spill 21 reaches the operation portion 6 and one of the touch switches The case of switching from the off state to the on state. Alternatively, the operation portion 6 may be covered by the falling object (rag, food, etc.) on the glass top plate 2, and the touch switch may be switched from the closed state to the open state, or the insect may be moved by the operation portion 6. The switch is switched from the closed state 12 1275748 state to the open state. Further, according to the factors other than the operation of the user, when the fire booster switch 13a for the left burner 4a is switched from the closed state to the open state during the combustion of the left burner 4a, the firepower of the left burner 4a is increased and Continue to adjust the heating of the 5 substances, then the conditioning material will be overheated and the conditioning fails according to the user's mind. In the combustion of the right burner 4b, the same applies to the user's operation, and the right fire extinguishing switch 13b for the right burner 4b is switched from the closed state to the open state. Therefore, in the combustion control mechanism 31 of the controller 30, the combustion of the left burner 10a is switched from the off state to the on state due to factors other than the user's operation. In the state, processing for preventing the state in which the amount of combustion of the left burner 4a is increased is performed. Further, similarly, the heating control mechanism 31 is in the combustion of the right burner 4b, and is configured to prevent the combustion of the right burner 4b from being continued when the right power booster switch 13b is switched from the closed state to the 15th open state. Increased state of the process. Hereinafter, the increase and decrease of the burner fire power by the heating control means 31 including the processes will be described based on the flowcharts of Figs. 4 to 5. Further, the flowcharts of Figs. 4 to 5 are processing of the left burner 4a, however, the processing for the right burner 4b 20 is also the same. The heating control unit 31 repeatedly executes the loop of the step 4 of the fourth drawing to the fourth step of the fifth drawing when the left burner 4a is in combustion. Further, in step 1, when the ignition preparation switch 11a is in the open state, the process proceeds to step 10, and the heating control means 31 closes the left burner on-off valve 41a and ignites the left combustion 13 1275748 4a. Further, 'Steps 11 to 12 are processed by the lighting control unit 32, and the lighting control unit 32 turns off the ignition preparation display unit 14a in step 11 and turns off the fire level display unit 15a in step S12. At the same time, the buzzer 18 is sounded in step 5 13 and the user is informed of the flameout of the left burner 4a. Next, in step 2, if the firepower lowering switch 12a is in the on state, then it is branched to step 20. Steps 20 to 22 reduce the heating power of the left burner 4a for a period of time, and the lighting control mechanism 32 causes the buzzer 18 to sound in step 20, and the rod of the fire level display portion 15a is made in step 21. The display 10 is reduced in the negative direction (the left direction in Fig. 2), and the user is informed of the decrease in the fire power of the left burner 4a. Further, in the next step 22, the heating control means 31 reduces the opening degree of the left burner thermal power regulating valve 42a by one step, and reduces the heating power of the left burner 4a by one. In the next step 23, if the firepower lowering switch 12a returns to the closed state, it proceeds to step 3 of Fig. 5, and if the firepower lowering switch 12a is still in the open state, then it branches to step 30. Further, in step S30, when the thermal power lowering switch 12a is configured to be continuously maintained in the "continuously open state" for a predetermined time (for example, one second) or more, the routine proceeds to step 31. Step 3 到 to step 33 is the same as the foregoing steps 20 to 22, and the fire power of the left burner 20a is reduced by one section. When the process returns from step 33 to step 23, and the firepower lowering switch 12a is "continuously turned on", the process proceeds from step 30 to step 31, and the processes of steps 31 to 33 are repeatedly performed. Therefore, the user can continuously and rapidly reduce the firepower of the left burner 4a to the minimum level by continuously touching the firepower lowering switch 12a and maintaining the firepower reducing switch 12a in the open state (level: 1) Next, in step 3 of Fig. 5, if the firepower rise switch na is in an open state, it branches to step 40. Further, the lighting control mechanism 32 causes the buzzer 18 to sound in step 40. And in step 42, the bar display of the fire level display portion 5 15a is increased in the positive direction (the right direction in FIG. 2), and the user is informed of the increase in the heating power of the left burner 4a. Further, in the next step 41, the heating control mechanism 31 increases the opening degree of the left burner thermal power regulating valve 42a by one step, and increases the heating power of the left burner 4a by one step. Further, in the next step 43, if the heating power rise switch 13a returns to the off state When the state is closed, the process proceeds to step 4. If the firepower riser switch 13a is still open, the process proceeds to step 50. If the firepower rise switch 13a is in the "continuously open state", the process proceeds to step 50. Step 51. Step 5 1 to 53 are the same processes as the above steps 20 to 22, and the heating power of the left burner 4a is decreased by one step. Further, after waiting for the 15th fire rise switch 13a to be in the closed state in step 54, the process proceeds to step 4, whereby When the firepower rise switch 13a is in the "continuously open state", the firepower of the left burner 4a which is once increased in step 42 will be reduced and restored in step 53. Here, the operation is covered by the overflow or the like. In the portion 6, when the fire power rise switch 13a is switched from the off state to the on state due to factors other than the user's operation 20, the virtual fire rise switch 13a is maintained for a certain period of time after being turned on, so at this time The system is configured to "continuously open state", and proceeds from step 30 to step 31, and in step 33, the firepower of the left burner 4a is reduced by one section. 15 1275748 Thereby, the firepower of the left burner 4a is maintained at the fire rise switch 13a is switched from the closed state to the state before the open state due to the overflow or the like, so that the operation portion 6 is covered by the overflow or the like, and the heating power rise switch 13a is switched from the closed state to the closed state. In the open state, it is possible to prevent the state in which the heating power of the left burner 4a is increased by 5 and the conditioning material is excessively heated. On the other hand, when the user wants to increase the heating power of the left burner 4a, it is only necessary to touch the left burning with a finger. The firepower riser switch 13a is used to release the finger before the "continuously open state" is formed, thereby proceeding from step 43 of FIG. 5 to step 4, and maintaining the fire power of the left burner 4a in step 42 is increased. Next, if an abnormality such as a flameout of the left burner 4a is detected in the step 4, the process proceeds to step 60, and the lighting control unit 32 causes the buzzer 18 to sound in step 6A. In step 61, the ignition preparation display portion 14a is suddenly turned on and off, and the user is notified of an abnormality. Further, the lighting control unit 32 causes the fire level display portion 15a to be turned off in the step 62. Further, in the next step 63, the heating control means 31 closes the left burner on-off valve 41a, blocks the supply of the fuel to the left burner 4a, and proceeds to step 64 to configure the error stop state. Further, in the present embodiment, the gas burner having the gas burners 4a and 4b as the heating means of the first embodiment is shown. However, the furnace having other types of heat and heat mechanisms such as electric heaters can also be applied to the present invention. . Further, the present embodiment shows that the glass top plate 2 using heat-resistant glass is the top plate of the present invention, however, the present invention having the top plate of stainless steel or the like can also be applied. Further, in the present embodiment, a static-capacity type touch switch is used as the stove of the touch switch of the present invention. However, the type of the touch switch is not limited thereto, and a light-emitting portion/light-receiving portion having infrared rays is used. The present invention can also be applied to a stove of a mechanical contact type touch switch such as a photoelectric switch or a touch switch. 5 [Simplified illustration of the drawings] Figs. 1(a) and 1(b) are views showing the appearance of the oven of the present invention.
