Description of the invention: Γ # Mingminghujin is a genus of sects. Technical field The present invention relates to a stove with a heating mechanism, and in particular, it is provided with a heating mechanism on the top plate for indicating the heating mechanism. The stove of the operating part. [^ Tr 才 支 4 标] [Background Art] In the past, as shown in FIG. 8, in a pan-type stove in which an opening of a stove body was previously prepared and buried in a countertop of a system-type kitchen, the cover was closed. The glass top plate 102 on the stove body 101 of the valley gas burner 100a and 100b is provided with detailed work 103a, l0 for ignition / extinguishment of the gas burner 100a and 100b and fire withering. 3b (see, for example, Patent Document 1). In the case of the stove described above, it is not necessary to provide an opening facing the operating portion in front of the countertop, as in the case where a stove having an operating portion is provided on the front surface. Therefore, the stove can be easily installed on the countertop. In addition, since the gas burner can be ignited / quenched or the fire power can be adjusted by operating the buttons 103a and 103b provided on the glass top plate 102 with good visibility, the operability of the user can be improved. [Patent Document 1] Japanese Patent Laid-Open Publication Nos. 58-186302, 20 [Disclosure of the Invention] According to the stove shown in FIG. 8, since the operation buttons 103a and 103b are protrudingly arranged on the glass top plate 102 , So it becomes an obstacle when conditioning. Therefore, it is conceivable to set the detection part of the electrostatic capacitance sensor on the glass top plate 102 on the 200535382 surface, and to form a contact switch with an operation part on the surface of the glass top plate 102 as gas burners 100a and 100. The operation mechanism b makes the upper surface of the glass top plate 102 flat. However, when the contact switch is provided on the surface of the glass top plate 102 as described above, the user may inadvertently touch the contact switch during conditioning. It also happens because a child pranks touches the contact switch, or the soup overflows from the conditioner such as the pot placed on the fire rack 104a, 104b, or the conditioning container placed on the glass top plate 102, or falls. Something up to the glass top plate 102 covers the contact switch. 10 And, because of these factors, for example, the contact switch for instructing ignition of the left burner 100Qa is switched from the off state to the on state, and the left burner 100a is ignited. Therefore, in order to solve the above-mentioned disadvantages, it is an object of the present invention to provide a stove which can prevent ignition treatment of a burner when a contact switch is switched from a non-detected state to a 15-detected state against the intention of a user. MEANS TO SOLVE THE PROBLEM This invention is made in order to achieve the said objective, and it relates to the improvement of the following stoves. The stove includes: a plurality of contact switches, which are operated by a user and are covered with a top 20 plate on the stove body that can accommodate a heating mechanism, so as to detect a contact or a close object facing the top plate. And a heating control mechanism, which is a processor who grasps that the contact switch is in a detection state or a non-detection state, and performs at least the start of the operation of the heating mechanism according to the grasped result. In addition, the heating control mechanism mentioned above is pre-selected among the above-mentioned multiple contact switches. 20052005382 When at least two contact switches selected first are switched from the non-detection state to the detection state, the processing for starting the operation of the foregoing heating mechanism is executed.

Therefore, when the user touches the switch unconsciously, or because the child's mischief or the condition overflows, the non-detection state is switched to the detection state, the front will act. Then, by this, it is possible to prevent the heating mechanism from being operated against the intention of using the material. 10 15 20 It also has a mechanism for changing the aforementioned heating, and 'the majority of the aforementioned contacts are 2 °: ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Zhuo Tianhua The heating amount changing mechanism controls the heating 4up switch at -0 heat 1, and the aforementioned addition ΪΓ1: described as: when the preparation switch is switched from non-detection, before execution: ⑽ non-detection difficult g to switch to detection status execution. Then the 34 heating mechanism starts processing. According to the above-mentioned present invention, the aforementioned heating mechanism is turned on and "4 heating amount up and off is used to refer to the number of contact switches: the switch can reduce the number of preparations that must be prepared in advance. Conceptually, the process of starting the heating mechanism is described by The aforementioned heating amount UP is turned on; the wide heating amount refers to * "towels, so the user is perplexed by the wrong indication of the instruction: the second step is good to start the aforementioned heating mechanism. θ're evening ', and the user's convenience will be changed, and the aforementioned multiple contacts have more than two _ minus 7 200535382 One of the switches is an operation switch, which can switch the user Er == off Γ turn state and the user can not operate other connections _ when = 2: machine operation _ outside to =: touch = 2 of the multiple contact switches can be switched from non-detected 5 detection status At that time, a process corresponding to the aforementioned mechanism is started. ^ The aforementioned heating of the contact switches according to the present invention described above, when performing the instruction from the aforementioned standby state-the activation of the actuator mechanism, use to ..., 10 15 20 ^ Only one hundred users must operate the aforementioned operating switch in order to follow The standby state is switched to the aforementioned operation state. Therefore, when the potable state is switched to the detection state, the processing of starting the heating mechanism is performed. In order to instruct the heating mechanism to start operating, two contact switches must still be operated. However, when it has been set to the aforementioned Korean cosmetics, the heating machine on the ^ = 2 line when any one of the ingredients is used as the material is added to the beginning of other heating mechanisms. When «Other than __detection = state switch to system«, if the above-mentioned other heating mechanism starts heating process', the operation of a contact switch will be used to start heating of the other processing mechanism. In addition, at this time, when one contact switch is switched from the non-detection state to the detection state due to the mischief of the user's unconscious child, the other heating mechanism will start to operate. w Therefore, according to the present invention, when the aforementioned operation switch is switched from a non-detected difficult state to a detected state by a tactile switch, the processing for starting the aforementioned drum-increasing mechanism is executed 'by this' in the aforementioned operating state to prevent violation of The user's heart performs a process of starting operation of any one of two or more of the aforementioned heating mechanisms. 10 15 More /, there are heating amount changing mechanisms individually provided in two or more of the heating mechanisms described above, and used to change the heating amount of the corresponding heating mechanism, and the majority of the above-mentioned contact switches include individually provided in two or more of the foregoing heating switches.

Number indicates the firepower of 4a when left burning Level (level 1 to level 5). For example, when the fire level of the left burner is 1, only the light on the left end of the stick display is turned on, and the fire level of the left burner 4 & When it is 5, all the five lighting parts of the stick display are turned on. Similarly, the 'firepower level display part 15b' also uses the lighting of the lighting part from the left in the stick display formed by the five lighting parts shown in the figure. The number of lamps indicates the firepower level of the right 15 burner cents (level 1 to level 5). • Next to 'Tea Photo 3', a controller is installed in the stove body to control the overall operation of the stove. 30, and the operation state of each switch of the operation section 6 (operation switch 10, ignition preparation switch 11a, 11b, thermal power switch OWN switch 12a, 12b, 'fire power UP switch 13a, 13b) (0) 1 / 〇 ly) The detection signal is input 20 to the controller 30. The control signals from the controller 30 are used to control the operation of the following mechanisms: to switch the fuel gas supply to the stove body or to block the gas source valve 40 Switching valve 41 for switching the supply of fuel gas to the left burner 4a or the left burner for blocking the supply a. The left burner fire control valve 4 (equivalent to the heating amount changing mechanism of the present invention) used to change the fuel gas supply 12 200535382 ^ left burner supply flow rate, high voltage is applied to the ignition electrode of the left burner 4a ( (Not shown) the left burner igniter 43a for generating spark discharge, the right burner switch valve 41b for switching the fuel gas supply to the right burner, and the supply 5 for changing the fuel gas supply to the right burner The right-burner fire control valve (corresponding to the heating amount changing mechanism of the present invention) of the supply flow rate of 4b, and the right burner igniter that applies a high voltage to the ignition electrode (not shown) of the right burner to generate a spark discharge. 431 ^. In addition, each display section (ignition preparation display sections 14a, 1413, fire level display sections 15a, 15b, and lock-free display section) provided in the operation section 6 is controlled by a control signal output from the controller 30. 16. The on / off light of the lock display unit 17) and the on / off of the alarm device 18. In addition, the controller 30 includes a heating control mechanism 31 for controlling the left burner such as the right burner and a control unit 18 for controlling the on / off of the display unit 15 of the operation unit 6 and the alarm device 18 The notification lighting control mechanism is 32 °. As described above, the contact switch provided on the operation section 6 can detect the presence or absence of an electrostatic body on the glass top plate 2. Therefore, except when the user touches the contact switch with a finger, as shown in FIG. 1 (b), when only the left burner know 20 is used to heat the conditioner in the pot 20, the conditioner may overflow. And the spill 21 reaches the operation unit 6 to switch the right burner servant contact switch from the off state to the on state. Or, it may happen that the user unconsciously touches the contact switch during conditioning, or because of a child ’s prank or a fall on the glass top 2 13 200535382 (cloth, food, etc.) or placed on the glass top 2 Conditioning the container, etc., when the contact switch is switched from the off state to the on state. Therefore, the heating control mechanism 31 included in the controller 30 performs the switching of the contact switch from the 0ff state to the 0n state in violation of the user's intention as described above. In the sad state, the left burner 4a or Processing of the instruction of the ignition operation of the right burner 4b. This process will be described below with reference to the flowcharts in FIGS. 4 to 7. The flowcharts in Figs. 4 to 7 mainly deal with the left burner 4a, but the same applies to the right burner 4b. First, STEP1 ~ STEP6 in Figure 4 are used to identify the situation where the operation switch 1010 is switched from the 0FF state to the QN state and then returned to the 0FF state. When the power is input to the stove and the controller 30 starts to operate, it becomes "standby-like evil", and the heating control mechanism 31 waits for the operation of the switch 10 in step 1 in Fig. 4 to be on.

the process proceeds to STEP2, and the two-second timer and the four-second timer are started to count, and in the circuit formed by the following sTEp3 and STEP30, it is confirmed that the operation is turned on at Step3. _ Maintain the on state and wait for the time of the 2-second timer to arrive in STEI> 3. When the time of the 2 second timer in the 20 C fertilizer has reached, that is, when the addition state of the operation switch 10 continues for more than 2 seconds, it proceeds to s. STEM and STEP5 are processed by the lighting control mechanism 32, and the casing light control mechanism 32 turns off the lock-free display section 16 and at the same time causes the game device 4 to sound, thereby notifying the user that the device has been accepted. Operation of the operation switch 10. On the other hand, when the operation switch 10 in the coffee 30 is not in the ON state, it can be judged that the operation switch ο is momentarily turned on due to noise or the like. Therefore, at this time, it returns to STEP and the heating control mechanism 31 waits again for the operation switch to switch from the 0ff state to the on state. In the loop formed by STEP6 and STEP35, the heating control mechanism 31 confirms that the time of the 4-second timer has arrived in STEP35 and waits for the operation switch 10 to turn off in STEP6. When the operation switch 10 becomes the 0ff state in STEP6, that is, when the operation switch 10 returns to the off state 4 seconds before the operation switch 10 becomes the on state in STEP1, the process proceeds to STEP7, and the heating control mechanism 31 makes 15 minutes. The 10-minute timer starts. On the other hand, when the time of the 4-second timer in STEP35 has reached, that is, when the on state of the operation switch 10 continues for more than 4 seconds, it proceeds to STEP80 in FIG. 7. Fig. 7 is a process for preventing shutdown. The lighting control mechanism 32 turns off the lock-free display section 16 in STEP80, turns on the lock display 15 and 17 in STEP81, and sounds the alarm device 18 in STEP82. . Then, the heating control mechanism 31 waits for the operation switch 10 to be on in the subsequent STEP83. Therefore, before the shutdown prevention state is released by the operation of the operation switch 10, it will be a shutdown prevention state in which all switches cannot be operated. If the user touches the operation switch 10 to make the operation 20 switch 10 in the on-off prevention state, the user advances from STEP83 to STEP84, and the heating control mechanism 31 starts the 4-second timer. Next, the heating control mechanism 31 confirms whether the operation switch 10 is on in the circuit formed by STEP85 and STEP90, and waits for the time of the 4-second timer to arrive in STEP85. When the time for the 4 second timer 15 200535382 in STEP85 has arrived, that is, when the user continues to touch the operation switch 10 in the shutdown prevention state, and the operation switch 10 becomes the ON state for more than 4 seconds, it proceeds to STEP86. In the subsequent STEP 86, the lighting control mechanism 32 turns off the lock display unit 17, and in STEP 87, the alarm device 18 sounds. 5 advances to STEP 1 in FIG. 4. This releases the anti-off state. When the operation switch 10 is turned off in STEP6 in FIG. 4, that is, 4 seconds before the operation switch 10 is turned on in STEP1, and the operation switch 10 is turned off, the process proceeds to STEP7 and the controller 30 starts the 15-minute timer. 10 Next, STEP14 to STEP14 in Figure 5 are used to identify the situation where the ignition preparation switch 1 la switches from the off state to the on state and then returns to the off state. The heating control mechanism 31 uses a circuit formed by STEP8 and STEP40 to confirm whether the time of the 15-minute timer has arrived in STEP40, and waits for the ignition preparation switch iia to switch from 0ff state to on state in STEP8. Then, when the ignition preparation switch 11a is turned on in STEP8, it proceeds to STEP9 in FIG. 5. On the other hand, when the time of the 15-minute timer in STEP 40 has arrived, that is, 15 minutes have elapsed from the time when the operation switch 10 was turned off in STEP 6, and the ignition preparation switch 11a has not been turned on, it proceeds to 2o. STEP41, the controller 30 causes the lock-free display section 16 to light, and the alarm device 18 is sounded in STEP42, and returns to STEP1 to "standby state". Accordingly, when the user operates the operation switch 10 and the ignition operation of the left burner 4a is not performed before 15 minutes have elapsed, the stove is returned to the "standby state". 16 200535382 In step 9 of Figure 5, "Heating control mechanism 31 starts the 1-second timer" and the circuit formed by the STEP10 and STEP50 of the receiver is used to determine whether the ignition ready switch 1 a is on in STEP50. Status, and arrive at STEP10 Nakajima at the time of 1 second. Then, when the time of the 15-second timer in stepio has reached, that is, when the ignition preparation switch 11a is turned on for more than 1 second, the process proceeds to STEP11. On the other hand, when the time of the 1-second timer in STEP50 has reached, that is, when the ignition preparation switch 11a is turned on for less than 1 second, it can be determined that the ignition preparation switch 11a has been turned on for an instant due to noise or the like. Therefore, at this time, it returns to STEP 7 in FIG. 4 and the heating control mechanism 31 waits again for the ignition preparation switch 11a to switch from the off state to the on state. STEP11 to STEP12 are processes performed by the lighting control mechanism 32. The lighting control mechanism 32 turns off the ignition preparation display unit 14a and sounds the alarm device 18 in STEPi2. Then, the heating control mechanism 31 starts counting the time in 2 seconds for 5 seconds from 13 seconds, and waits for the ignition preparation switch na to become 0ff in STEP14 through the loop formed by the following stepi4 and STEP%. 0 When the ignition preparation switch 11a becomes 0ff in STEP14, that is, 1 second after the ignition preparation switch 11a becomes on, and the ignition preparation switch 11a returns from on-state to off within 2 seconds, it proceeds to STEPi5 And the heating control mechanism 31 starts the 10-second timer. On the other hand, when the time of the 2-second timer in STEP55 has reached, that is, after the ignition preparation switch 11a becomes the on state, and the ignition preparation switch Ua continues to be the on state for 2 seconds, the process proceeds to STEP56. Then, the controller 17 200535382 30 turns off the ignition preparation display portion 14a in STEP56, and sounds the alarm device 18 in STEP57, and returns to STEP7 in FIG. 4. Accordingly, when the ignition preparation switch 11a is maintained in the on state due to the overflowed soup or the like, it is possible to prohibit the processing subsequent to STEP 15 without performing the ignition processing of the left burner 4a. Next, STEP19 to STEP19 in Figure 6 are used to identify the situation in which the firepower UP switch 13a is switched from the off state to the on state and then returned to the state. The heating control mechanism 31 starts the 10-second timer in STEP15, and advances to STEP16 in FIG. 6, and confirms whether the time of the 1-second timer has arrived in STEP60 by forming a loop of 10 from STEP16 and STEP60, and In STEP 16, it is waited for the firepower UP switch 13a to switch from the off state to the on state. When the thermal power up switch 13a is turned on in STEP 16, that is, when the thermal power up switch 13a is switched to the on state within 10 seconds after the ignition preparation switch 11a is turned off, the process proceeds to STEP17. STEP17 and STEP18 are the processes performed by the lighting control mechanism 32. The lighting control mechanism 32 lights the fire level display unit 15a at level 4 in STEP17, and sounds the alarm device 18 in STEP18, and proceeds To STEP19. Here, when the firepower UP switch Ha is turned on in STEP16, the ignition process of the left burner 4a performed in STEP20 described later is performed first, and the firepower level display portion 15a is lit in 20STEP17, thereby Notify the user that the ignition instruction has been accepted. On the other hand, when the time of the 10-second timer in STEP60 has reached, that is, even if 10 seconds have passed after the ignition preparation switch 11a is turned off, the thermal power switch 13a has not been switched to the on state, and the process proceeds to STEP61. 18 200535382 STEP61 ~ STEP62 are processes performed by the lighting control mechanism 32. The lighting control mechanism 32 turns off the ignition preparation display unit 14a in STEP61, and sounds the alarm device 18 in STEP62, and returns to gjTEp7 in FIG. 4 . With this, the heating control mechanism 31 waits again for the ignition preparation switch 11a to switch from the 0ff state to the on state. The heating control mechanism 31 uses the circuit formed by STEP 19 and STEP 65 to confirm whether the time of the 10-second timer has arrived in STEP 65, and waits for the fire power UP switch 13a to return to the off state in STEP 19. Then, when waiting for the fire power UP switch 13a to return to the off state in STEP19, it proceeds to 10 STEP20, and when the heating control mechanism 31 activates the igniter 43a to open a spark discharge at the ignition electrode, the gas source valve 40 and The left burner on-off valve 41a and the left burner fire control valve 42a are set to the fire power level 4 to perform the ignition process of the left burner 4a (equivalent to the process of starting the operation of the heating mechanism of the invention). 15 On the other hand, when the time of the 10-second timer in STEP65 has arrived, that is, within 10 seconds after the ignition preparation switch 11a becomes the on state, the fire power UP switch 13a is switched from the off state to the on state, and is restored to off In the state, it proceeds to STEP66. STEP66 and STEP68 are processes performed by the lighting control mechanism 32. The lighting control mechanism 32 turns off the ignition preparation display section 20 and 14a in STEP66, and turns off the fire level display section 15a in STEP67, and turns on in STEP68. The alarm device 18 sounds and returns to STEP 7 in FIG. 4. As explained above, after the heating control mechanism 31 is switched to the off state- > ON state-off state, the ignition preparation switch 11a is switched to the off state- > on state- > off state, and When the fire power UP switch 13a is switched to the off 19 200535382 state—on state—off state, the ignition process of the left burner 乜 is executed. Therefore, when the user inadvertently touches the operation section 6, or because of a child's mischief or soup overflowing, only one of the operation switch 10, the ignition preparation switch 11a, and the fire power UP switch i3a is changed from 0ff When switching from the 5 state to the ⑽ state, or from the ON state to the off state, the ignition process of the left burner 4a is executed. In addition, even after the "operation state" is reached, when one of the ignition preparation switch 11a and the fire power UP switch 13a is switched from the 0ff state to the 0n state, or returned from the cm state to the off state, left combustion is not performed. Know the point 10 fire treatment. In this embodiment, although the stove having the gas burners 4a and 4b is shown as the heating means of the present invention, the present invention is also applicable to stoves having other types of heating means such as electric heaters. Moreover, in this embodiment, although the use of an electrostatic capacity type contact opening 15-off stove is shown as the contact switch of the present invention, the type of the contact switch is not limited to this, even if a light-emitting section / light-receiving section having infrared rays is used. The invention also applies to stoves of mechanical contact-type contact switches such as optical switches or contact switches. In this embodiment, although a stove having a heat-resistant glass 20 glass top plate 2 is shown as the top plate of the present invention, depending on the type of contact switch, a stove having a top plate of other materials such as stainless steel is also used. The present invention is applicable. In this embodiment, although a stove having two burners serving as heating means is shown, a stove having one heating means or a stove having three 20 200535382 or more heating means may be used. The invention is applicable. In addition, in this embodiment, although the stove which has an operation switch is shown, the effect of this invention can be acquired also with the stove which does not have an operation switch. Moreover, in this embodiment, although the fire power UP switches 13a and 13b are divided into five and are used as switches for instructing ignition of the left burners 4a and 4b, in order to reduce the number of contact switches in the operation section 6, The switches for instructing ignition of the left burners 4a, 4b and the fire power UP switches 13a, 13b are individually provided. Moreover, in the present embodiment, although the operation switch 10, the ignition preparation switch 11a, and the thermal power-up switch 13a are shown in the flowcharts of FIGS. 4 to 6, after switching from the Off state to the On state, When returning from the on state to the off state, the process proceeds to the next STEP, but when switching from the off state to the on state, the process proceeds to the next STEP. The effect of the present invention can also be obtained.
