Description

Electric cooker

Technical field

The present application relates to the structure of electric cooker, has the existing people for receiving the infrared detection people from human body Body induction sensor, and controlled electric cooker for desired action state based on the testing result.More specifically, it is related to The structure of electric cooker be, also can reliably will be electric in the case where the detection function of the people's body induction sensor is insufficient The controls such as the operation configuration part of rice cooker are desired action state.

Background technique

In nearest electric cooker, the electric cooker for having following function is provided: not only having common rice (rice) and boil The function of meal, and be also equipped with and for example boil brown rice (profound rice) or Coarse cereals rice (miscellany paddy), hodgepodge (Write body of cooking a meal), boil glutinous rice red bean meal The rice-cooking function of (お こ わ), congee (お か ゆ) etc., boil (I of early cooking a meal) fastly, economy boils functions such as (エ Us cook a meal I), and on having It states the adjusting of the large and small fire in each situation or the adjusting of cooked degree, sound instruction (speech ガ イ De) and the cooking, interior pot is washed The functions such as net.

In this electric cooker for having various function, the operation panel portion of the operation setting for carrying out above-mentioned each function The quantity for the Operation switch divided also increases, and the displayed quantity of the display panel part for information needed for showing aforesaid operations also increases More (referring for example to the structures of electric cooker shown in patent document 1).

In the case where the electric cooker of this structure, AC electricity is connected on the intracorporal power circuit of electric cooker master certainly Source other than microcomputer control unit, needs to grasp operation panel side under the operation standby mode for waiting its operation setting While making the various switching circuits on substrate and be maintained state of activation, the liquid crystal display drive circuit of display panel side is tieed up It holds and therefore always consumes the electric power of the waste of specified amount or more for driving condition, if stand-by time extends, with extension amount Correspondingly consume extra electric power.

Therefore, in order to solve this project, currently, motion has following technology, when adding real-time to microcomputer control unit Clock function (RTC function), in the case where exceeding schedule time without carrying out necessary operation setting behavior, automatically transition To the energy-saving mode of the power supply of saving (or closing) peripheral circuit, the reduction of consumption electric power is realized.

Moreover, using the electric cooker of this energy-saving mode, under the energy-saving mode, certainly, as long as obstructed It crosses certain means and releases the energy-saving mode, though the operation for then carrying out Operation switch is also invalid (cannot input), and It can not carry out the display or illumination of display panel.

Therefore, under the operation standby mode, using the electric cooker of energy-saving mode, from the standby shape of the operation Recovery of the energy-saving mode to the common standby mode for being able to carry out operation setting under state, usually passes through setting and original behaviour Make to switch different dedicated energy-saving mode cancel switches, and presses the cancel switch as needed to carry out.

Summary of the invention

(problems to be solved by the invention)

Really, energy-saving mode is released when setting energy-saving mode releases dedicated Operation switch and presses the Operation switch When, can reliably it restore to the common standby mode for being able to carry out operation setting.

But in this case, dedicated Operation switch is released from needing to be arranged energy-saving mode, in addition, it is desirable to carry out every time For in the sense that opening operation, there are problems that lacking convenience.In addition, being opened being equipped with the dedicated operation of energy-saving mode releasing In the case where pass, it is easy to produce the presence for being not easy to find the switch or generates to forget to press and set without can be carried out necessary operation The problem of fixed misunderstanding or product failure.

It is this to solve the problems, such as, it is expected that electric cooker itself has the existing function of detection people, is existed according to people or do not deposited , such as the standby mode being maintained under the energy-saving mode that not can be carried out operation setting input, or revert to and be able to carry out operation Set input normal mode standby mode etc., can by the energized state of operation panel, display panel to the electric cooker, The state of a control control of working condition etc. is desired state.

Therefore, in order to cope with such expectation, inquired into the setting for example in the electric cooker receive radiated from human body it is red Outside line and the infrared-type whether having users in position corresponding with electric cooker as defined in operation corresponding position etc. detected Human body sensor.

In this way, being able to detect the defined of the electric cooker in the case where being provided with human body sensor on electric cooker The presence of user in corresponding region (does not have in the case where defined corresponding position relative to electric cooker main body in user The case where detection input of human body sensor) under, by the Operation switch portion of the operation panel and the display of display panel Portion, illumination portion etc., which are automatically set, is maintained energy-saving mode, consumption electric power is reduced as much as possible, on the other hand, in user in institute Under the case where stating corresponding position (having the case where detection of human body sensor inputs), the energy conservation mould can be automatically contacted Formula reverts to the normal mode for being able to carry out desired operation setting input and display, illumination.Therefore, with it is above-mentioned previous Setting energy-saving mode release dedicated Operation switch and it is every it is secondary carry out operation setting when have to open on the switch The case where operation, is compared, and convenience is high.Furthermore, it is not longer necessary to which energy-saving mode, which is arranged, releases dedicated Operation switch.

But in carrying out various discussions, developing, distinguishes and also deposited in the case where being equipped with this human body sensor In some problem.The problem of one of problem is the insensitive region of the people's body induction sensor.

That is, the human body sensor of infrared mode, from its characteristic, temperature-dependent characteristics are high, input regulation While more than temperature infrared ray, the presence of the people (user) as object is detected according to the variation of the input direction.And And due to detection be people, so the defined temperature of the infrared ray that should be detected, certainly on the basis of the body temperature of people, and On the basis of the input quantity of the infrared ray of body temperature radiation based on people.

But the lower temperature that the body temperature of people is 36.5 DEG C or so, in full summer etc., the biography of the human body sensor Atmosphere temperature (room temperature) around sensor portion also rises to same temperature sometimes.In addition, being also easy the heating by air-conditioning etc. The influence of device temperature.Under such circumstances, cannot distinguish between to the human body sensor input infrared ray amount be due to Ambient temperature there are problems that not can be carried out correct people's detection still due to the radiation from user's body.That is, damage human body The reliability of the detection input of inductive pick-up itself.

In addition, human body sensor, such as by having sensitive lens and by the light from external infrared light optically focused It portion and receives by the infrared light of the acceptance part optically focused and exports the light receiving circuit portion of electric signal and constitute, make the light by acceptance part The infrared light of lens entrance is selected as the light of preset band domain by infrared filter, and pyroelectricity converges in light receiving circuit Pyroelectricity element part in portion hinders voltage signal corresponding with the light income exported from the pyroelectricity element part Resistance changes, and exports after the voltage level as defined in being enlarged into.

The pyroelectricity element, by a pair of of pyroelectricity by for example being constituted as the pyroelectric ceramics of one kind of piezoelectric ceramics Electrode is with the state that is parallel to each other and sets and is constituted, and using above-mentioned a pair of of the pyroelectricity electrode being parallel to each other, is detected respectively to entering The distance of the light source for the infrared light penetrated, and the variation of the difference of each detecting distance in the time detects the shifting of user according to the rules It is dynamic, and determine whether there is user.

Therefore, in the sensitive lens part of the acceptance part, it is inevitable in the circumferential direction there are the limitations of incidence angle, in addition, should Incidence angle, the infrared ray introducing port for being also formed on electric cooker part are limited to the opening diameter and depth of human body sensor System.

As a result, creating the problem that such as from the side portion of electric cooker main body or rear part, human body induction When operation panel to be operated only is stretched out one's hand in non-detectable region outside the ranges of incidence angles of sensor etc., the human body sensing sensing Device cannot detect the presence of user, cannot release energy-saving mode, therefore, although user carries out unlatching behaviour to necessary Operation switch Make, operation setting can not be carried out.

Further, in the case where cap portion is equipped with human body sensor, it is also considered that the height blown out from steam component The infrared ray introducing port part that " the meal thin rice gruel " of temperature flows to human body sensor can make human body although not having users Inductive pick-up becomes the state detected.Accordingly, there exist identical as the high situation of the atmosphere temperature around the sensor portion The problem of.In addition, the problem in this temperature is able in the case where " the meal thin rice gruel " is cooled to the state lower than the body temperature of people It eliminates, but then, due to the cover of " meal thin rice gruel " covering infrared ray introducing port, so in the presence of human body sensor is made Sensitivity decrease, and the problem of reduce detection function.

The present patent application is the such technical task of solution and is completed, it is intended that a kind of electric cooker is provided, Even if substantially needing to release energy-saving mode in the case where human body sensor can not achieve detection function appropriate When, operation portion can also be controlled to the state for that can operate.

(technical solution for solving technical problem)

The present patent application to achieve the above object, has following technical solution and constitutes.

(1) technical solution of the present invention

Technical solution of the present invention provides a kind of electric cooker, has: interior pot；Electric cooker main body can store with taking out The interior pot；Interior pot heating device heats in the electric cooker main body and to the interior pot of the storage；Lid, energy The enough top for being openedly and closedly set to the electric cooker main body；Control device, interior pot heating device when control is cooked or kept the temperature Heated condition；Operation portion carries out the operation setting of the control input to the control device, by multiple behaviour in the energized state Make switch to constitute；Human body sensor, detection operate the operation portion operator whether there is, operator there are the case where Under, on the other hand operation portion control is not present to be able to carry out the energized state of the setting of control input in operator In the case where, the non-power status that operation portion control not can be carried out into the setting that control inputs, the spy of the electric cooker Sign is, is controlled as not can be carried out the non-power status of the setting of control input and the human body sensing in the operation portion Sensor is not detected in the presence of the operator, and the operation of the operation portion described in operator's practical operation is opened Guan Shi can also make the operation portion revert to the energized state for being able to carry out the setting of the control input.

In this way, not only having the operation setting for carrying out the control input to micro computer equal controller in the energized state Operation portion, and be also equipped with detection operate the operation portion operator whether there is, in the presence of operator, by the behaviour The energized state for making portion's control to be able to carry out the setting of control input on the other hand, will in the case where operator is not present Operation portion control is the human body sensor that not can be carried out the non-power status of setting of control input, above-mentioned such In electric cooker, even if being controlled as not can be carried out the non-power status of the setting of control input and the people in the operation portion Body induction sensor is not detected in the presence of the operator, at least operates described in operator's practical operation The Operation switch in portion and will make the operation portion revert to be able to carry out it is described control input setting energized state when, In the case where the detection function for being difficult to rely on human body sensor, such as: it be outside the detection zone of human body sensor Atmosphere temperature around the sensor portion of the case where Operation switch of operating provision or human body sensor is the body temperature with people In the case where more than identical temperature, and have the case where influence of " meal thin rice gruel " etc., it also can be in practical operation operation portion The timing of Operation switch restores the operation portion reliably to the energized state for the setting for being able to carry out control input.

Therefore, the case where to operate Operation switch outside the detection zone from human body sensor or human body sensing sensing The sensor portion atmosphere temperature of device is temperature identical with the body temperature of people or more and the detection function of human body sensor cannot The case where playing a role appropriate, in the case where having the influence of " meal thin rice gruel ", also can reliably input respectively, set it is necessary Cook or keep the temperature information.

(2) technical solution of the present invention

Technical solution of the present invention provides a kind of electric cooker, has: interior pot；Electric cooker main body can store with taking out The interior pot；Interior pot heating device heats in the electric cooker main body and to the interior pot of the storage；Lid, energy The enough top for being openedly and closedly set to the electric cooker main body；Control device, interior pot heating device when control is cooked or kept the temperature Heated condition；Operation portion carries out the operation setting of the control input to the control device, by multiple behaviour in the energized state Make switch to constitute；Human body sensor, detection operate the operation portion operator whether there is, operator there are the case where Under, on the other hand operation portion control is not present to be able to carry out the energized state of the setting of control input in operator In the case where, the non-power status that operation portion control not can be carried out into the setting that control inputs, the spy of the electric cooker Sign is that the operation of the operation portion will be operated by having different from the human body sensor, the detection operator Detection sensor is controlled as not can be carried out the non-power status of the setting of control input and the human body in the operation portion Inductive pick-up is not detected in the presence of the operator, is detecting that the operator will operate the operation When portion, making the operation portion never and can be carried out the non-power status of the setting of the control input to revert to, to be able to carry out control defeated The energized state of the setting entered.

In this way, when the human body sensor that setting detection people whether there is on electric cooker is able to detect and operates the behaviour When the operator for making portion whether there is, in the presence of operator, will be with the control of the operation portion of multiple Operation switches It is able to carry out the energized state of the setting of control input, the operation for being able to carry out the necessary control input premised on cooking is set It is fixed, on the other hand, it is not present in operator, does not carry out the operation standby mode of any operation setting premised on to cook In the case of, the non-power status that operation portion control not can be carried out the setting that control inputs can save consumption electric power Waste.

On the other hand, under the non-power status, when operator will start new operation etc., even if not operating actually Operation switch, since the human body sensor detects the presence of operator in advance, can be incuded by the human body The detection of sensor inputs and restores the operation portion to the energized state for the setting for being able to carry out control input, so as to Carry out the operation setting of the necessary control input premised on cooking.

But such as above-mentioned, the human body sensor, the atmosphere temperature around its sensor portion is the body temperature with people More than identical temperature situation or in the case where having the influence of " meal thin rice gruel ", may not being capable of proper function.Therefore, in the shape Under state, it cannot restore from non-power status as described above to energized state, it may occur however that although the desired progress of user is necessary The setting for controlling input can not also carry out the case where controlling the setting of input.

It therefore, in the technical scheme, will by the way that different from the human body sensor, detection operator is arranged The operation detection sensors different from the function of human body sensor for operating operation portion, even if the human body sensor Cannot normally detect the presence of operator and not yet carry out Operation switch operation, at least it is actually detected to operator will Operate operation portion in the case where, judgement need to release non-power status so that the operation portion never can be carried out it is described control it is defeated The non-power status of the setting entered restores to the energized state for the setting for being able to carry out the control input.

Accordingly, in the feelings that the sensor portion atmosphere temperature of human body sensor is temperature identical with the body temperature of people or more Condition or in the case that human body sensor is unable to proper function due to the influence of " meal thin rice gruel ", is passed through and is detected using the operation Sensor detects user in advance will operate operation portion, and restore non-power status to energized state, energy in detection timing Each Operation switch of the operation portion is enough set to move to the state for being able to carry out operation input rapidly.

It therefore, is temperature identical with the body temperature of people or more in the sensor portion atmosphere temperature of the human body sensor And the detection function of human body sensor the case where cannot being properly acted or the human body due to influence of " meal thin rice gruel " In the case that the detection function of inductive pick-up cannot be properly acted, it also can reliably input respectively and set necessary boil Meal information.

Also, in the case where composition of the invention, the operation detection sensor is sensed by surrounding the human body sensing Electrostatic attraction electrode around device is constituted with the electrostatic capacitance detection sensor for detecting the capacitor that swims near the electrostatic attraction electrode, described The detection sensitivity of electrostatic capacitance detection sensor is set to, and detects the human body of the operator not in contact with the electrostatic electricity Pole and the capacitor that swims in the position of distance as defined in leaving increases specified value or more, the operation portion can be made never and can be carried out institute The non-power status for stating the setting of control input reverts to the energized state for being able to carry out the setting of control input.

Therefore, operator touch electrode part unlike touch electrode, only by making human body sensor part Hand is covered near electrode for target, it will be able to detect that operator will operate, can make the operation portion from The non-power status that not can be carried out the setting of the control input successfully reverts to the logical of the setting for being able to carry out control input Electricity condition.

In addition, the operation detection sensor is led to independently of the operation portion for the setting for carrying out control input to control device It is crossed to surround around specific human body sensor there are position and be substantially wholely set with human body sensor.Cause This, operator is easy the presence of discovery operation detection sensor, moreover, with relative to the identical feeling of human body sensor Palm is covered, masking palm also becomes easy.

(3) technical solution of the present invention

The technical scheme is that in the structure of above-mentioned technical proposal, which is characterized in that constitute the multiple of operation portion Operation switch, by having multiple soft-touch controls of membrane keyboard and being illuminated to the touch key section of multiple soft-touch control Lighting device constitute, human body sensor constitute it is as follows: the presence of operator is not detected more than the lasting stipulated time In the case where, non-power status is moved to, so that the setting of each control input not can be carried out, and lighting device extinguishes and makes It is invisible from outside.

In this way, constituting multiple Operation switches of operation portion by having multiple soft-touch controls of membrane keyboard and to multiple touch The lighting device that the touch key section of switch is illuminated is constituted, and is continued more than the stipulated time not in human body sensor In the presence of detecting operator, non-power status is moved to, while not can be carried out the setting of each control input, is shone Bright device extinguishes and becomes from external invisible, and in the case where above-mentioned composition, there is no to switching circuit or lighting device Power consumption brought by unnecessary energization, energy-efficient performance improve.In addition, the behaviour of the electric cooker main body under operation standby mode Make the novel design in face, customer's attraction when sale improves.

In the case of that construction, when moving to non-power status, user cannot differentiate each soft-touch control position or Species can become the reason of maloperation if memory is suitably operated.In addition, preferential power saving function, not only makes Lighting device is closed, but also itself working power of the operation input circuit of soft-touch control is made to be also switched off or be reduced to saving State determines it is thus impossible to normally input.Therefore, it constitutes in this state are as follows: any soft-touch control no matter is operated, The operation is all invalid and cannot be entered.

Therefore, the case where Operation switch is operated outside the detection zone from the human body sensor or human body sensing pass Atmosphere temperature around the sensor portion of sensor is the detection of temperature identical with the body temperature of people or more and human body sensor The case where function cannot be functioned suitably and under having the case where influence of " meal thin rice gruel " etc., human body sensor User cannot suitably be detected to electric cooker main body in the case where, be set always without cooking or keeping the temperature the input of information It is fixed.

Therefore, in the case of this kind of construction, as shown in preceding solution, even if in nobody's body-sensing inductive sensing In the case that the people of device detects input, either one or two of multiple soft-touch controls of operation portion by the timing of carry out touch operation or The timing that operator will be operated is detected by the operation detection sensor different from human body sensor, is able to detect Operator will operate operation portion, need to release energy-saving mode, at this point, correspondingly making this first with above-mentioned either case The operation input circuit and each lighting device of multiple soft-touch controls restore to energized state, are able to carry out setting for control input It is fixed, while lighting device is lighted, can clearly show position and the species of each soft-touch control.

On this basis, it is properly entered the desired soft-touch control of operation, passes through operation input corresponding with the switch Circuit carries out the setting of necessary control input.

(4) technical solution of the present invention

The technical scheme is that in the structure of above-mentioned technical proposal, which is characterized in that control device, for making The non-power status for obtaining the setting that never can be carried out control input is restored to the energized state for being able to carry out the setting of control input Operation portion operation, the judgement without operation input.

Due to for making the non-power status for the setting that never can be carried out control input restore defeated to control is able to carry out The operation of the initial operation portion of the energized state of the setting entered, as long as releasing the high non-power status of energy-efficient performance and returning to energy The energized state for enough carrying out the setting of control input therefore, there is no need to such as setting input and cook, keep the temperature the case where information The correct operation of the operation object (switch) in such specific operation portion can pass through not specific operation object (switch) or spy Determine the arbitrarily touch operation of the quantity (quantity of switch) of operation object and reliably lifts non-power status.Therefore, with it is upper It is undesirable that the operation for stating operation portion, which correspondingly carries out the judgement of operation input,.

In particular, operation portion is made of the multiple soft-touch controls for having membrane keyboard as the technical program is equally configured to, Each has lighting device respectively, under the non-power status in view of the energy-efficient performance, above-mentioned each illumination dress Set extinguishing and from external invisible each soft-touch control, in this case, since lighting device is not lighted, soft-touch control is not shown, Therefore, the correct touch operation of specific operation object itself not can be carried out.Therefore, if making the input by aforesaid operations Judgement be able to carry out if, then be easy to produce mistake control input setting.

Therefore, the composition of the technical program is to make the non-power status that never can be carried out the setting that control inputs extensive In the judgement of the mode of operation of multiple soft-touch controls of the multiple energized state to the setting for being able to carry out control input, behaviour is only determined Any one or more the such operations for making above-mentioned multiple soft-touch controls are true, and are operated without which Operation switch Control input setting input determine.

The setting of the control input of the operation bring mistake of the soft-touch control of mistake is reliably avoided as a result,.

(5) technical solution of the present invention

The technical scheme is that in the structure of above-mentioned technical proposal, which is characterized in that not can be carried out, control is defeated Under the non-power status of the setting entered, in the case where the detection input for having human body sensor, make human body sensor Detection input it is preferential and restore to the energized state for the setting for being able to carry out control input.

As shown in the technical program, the non-power status as the setting for never to can be carried out control input restores to energy The device for enough carrying out the energized state of the setting of control input equipped with the recovery device realized by human body sensor and leads to In the case where crossing the two devices of the recovery device of operation realization of the Operation switch of operation portion, do not work in any recovery device When, also can reliably be restored using another recovery device, from this point on for, can be realized and more reliably restore function.

But in this case, it is preferred that if being inputted if there is the normal detection of human body sensor, preferably Non-power status is released to be preferential with the detection input of human body sensor, is restored to energized state, only in no human body In the case that the people of inductive pick-up detects input, using the Operation switch for operating operation portion as condition, non-power status is released.

User suitably close to electric cooker main body in the case where, compared with the Operation switch in touch operation portion, human body sensing Sensor senses user approaches earlier, and the responsiveness that energy-saving mode releases is also high.In addition, due to can be certainly without any operation It releases dynamicly, therefore, convenience is also high, and due to that can set control by the operation of the Operation switch of initial operation portion System input, so not needing the operation for only releasing the waste of non-power status.

(6) technical solution of the present invention

The technical scheme is that in the structure of above-mentioned technical proposal, which is characterized in that operation detection sensor by The electrostatic transducer for having electrostatic attraction electrode is constituted, and the operation detection sensor being made of the electrostatic transducer is passed set on human body sensing Near sensor.

Have the electrostatic transducer of electrostatic attraction electrode, passes through the capacitor energy that swims generated between measurement electrostatic attraction electrode and human body Enough reliably detect the presence of people.Moreover, not only people is direct if making the detection sensitivity be increased to specified value or more The case where contacting electrostatic attraction electrode, even if only by covering palm in the position of leaving for leaving distance as defined in electrostatic attraction electrode or more Capacitor increase of swimming can effectively be made, the presence of people is able to detect, therefore, suitable for the operation of electric cooker will be operated for user Portion will release non-power status and aforehand be detected.

Moreover, in this case, the Operation switch of the electrostatic transducer and operation portion is provided independently from, there are positions to set When near specific human body sensor (around such as), user is easy the presence of discovery electrostatic transducer, moreover, with Palm is covered with relative to the identical feeling of human body sensor, masking palm also becomes easy.Therefore, can more may be used It leans on and responsiveness higher detects user will operate operation portion.

Therefore, operation portion will operated using the operation detection sensor detection user being made of the electrostatic transducer When, non-power status is released immediately and restores operation portion to the energized state for the setting for being able to carry out control input, thus, When operating operation portion, the setting of control input can be just carried out since its initially operation of (first time).

It accordingly, such as in the sensor portion atmosphere temperature of human body sensor is temperature identical with the body temperature of people or more The case where or in the case that human body sensor is unable to proper function due to the influence of " meal thin rice gruel ", passed by the electrostatic Sensor detects the timing of the touch operation of user, and making the multiple Operation switch is respectively the state that can be inputted, thus, it is possible to Enough so that restoring rapidly from the preparation state that energy-saving mode etc. not can be carried out input to the common standby shape for being able to carry out input State.

It therefore, is temperature identical with the body temperature of people or more in the sensor portion atmosphere temperature of the human body sensor And the detection function of human body sensor the case where cannot suitably functioning or the human body sense due to influence of " meal thin rice gruel " In the case that the detection function of inductive sensing device cannot suitably work, the necessary letter of cooking of setting also can be reliably inputted respectively Breath.

(7) technical solution of the present invention

The technical scheme is that in the structure of above-mentioned technical proposal, which is characterized in that the touch electricity of soft-touch control Pole portion is arranged using inscription plate, and the thickness for being formed as the part corresponding with touch electrode of the inscription plate is thinner than other parts.

In the case of that construction, even if in the case where the respective lighting device of soft-touch control extinguishes, due to described The thickness for engraving the part corresponding with the touch electrode of each soft-touch control of plate is thinned, thus also can be visible each to a certain extent The touch electrode portion of soft-touch control periphery can relatively easily differentiate shape and the position of the soft-touch control.

Therefore, following situation can be corresponded to: carrying out the releasing of non-power status by aforesaid operations detection sensor On the basis of, and with the function for the releasing for carrying out non-power status and the touch to soft-touch control.

In addition, since the distance between electrode portion and human body become close, relative dielectric constant also increases, so the detection of electrostatic Sensitivity raising, Operational Figure Of Merit improve.Therefore, it is able to carry out easier operation, the detection sensitivity for switching operation also mentions It is high.

(The effect of invention)

It is above as a result, applying according to the present invention, although the Operation switch of operation portion, human body will be operated in user Inductive pick-up does not work in insensitive region, its detection function yet, and the input without can be carried out necessary information of cooking is set In the case where fixed, it can reliably restore to be able to carry out the input setting of information of cooking to energized state from non-power status, In the case where being equipped with human body sensor, original operation sense appropriate can not be damaged and carried out using Operation switch The input for information of cooking is set.

It in the case where the embodiment, as described below, consists of: being equipped with detection behaviour on above-mentioned micro computer substrate 60B Make human body sensing having users in corresponding region as defined in corresponding position etc., being for example made of thermoelectric type sensor to pass Sensor MS, regardless of standby mode, non-standby state and other electric cooker working conditions, such as in cooking, timing Under the operation standby mode in addition to standby mode in device reservation, after the control input setting that heat preservation is medium, do not exist in user (human body sensor MS is not detected more than the stipulated time in the case where operating in corresponding region as defined in corresponding position etc. In the presence of user), by the membrane keyboard of aforesaid operations switch SW1~SW11, touch sensor, light emitting diode L1~ The controls such as light emitting diode L20~L24 of L19, liquid crystal display panel 60A are aftermentioned WAIT mode (energy-saving mode), in liquid crystal surface On the basis of the display function or illumination functions of plate, by by the operating function of aforesaid operations switch SW1~SW11 or illumination function It can be set to close, reduce consumption electric power as much as possible.

As a result, above-mentioned waterproof cover 80 is for example by the translucent body of black or colored transparent body under the power save mode It constitutes, also, for example shown in Fig. 1, the upper surface of the lid 2 of the electric cooker main body becomes " opaque sootiness state ", removes down It is sightless state except the light of the human body sensor MS stated the part concave 80a.

Certainly, in this case, carry out for example " in cooking ", " in timer preset ", the operation of " in heat preservation " etc. it is standby Necessary display other than state.

The structure of human body sensor of the < in relation to cap portion and its setting construction >

In the case of this embodiment, such as shown in Figure 1, Figure 2 and shown in Fig. 7, Fig. 8, in the portion that the front of lid 2 keeps left It is arranged with above-mentioned human body sensor (action sensor) MS.The people body induction sensor MS has for example such as Fig. 9~figure Such structure, consists of shown in 12, as confirmation, state of cooking or the heat preservation that setting state is set or operated by operation The confirmation etc. of state, clock display operates corresponding position, its upper part of the body come the face side for detecting user close to the electric cooker main body People's detection sensor that (such as shoulder or face, hand etc.) is come in operation panel portion 60 and play a role.

That is, the people body induction sensor MS, by having sensitive lens 91 and by the light from external infrared light optically focused It portion 90a and receives the infrared light by acceptance part 90a optically focused and exports light receiving circuit portion (sensor main body portion) 90b of electric signal It constitutes, makes to select by the incident infrared light of the sensitive lens (Fresnel lens) 91 of acceptance part 90a by infrared filter 92 After being selected as the light of preset band domain, 93 part of pyroelectricity element in light receiving circuit portion 90b is collected in, passes through FET96 pairs Voltage signal corresponding with the light income exported from 93 part of pyroelectricity element carries out impedance transformation, as defined in being enlarged into It is exported after voltage level.

In the case where the embodiment, above-mentioned pyroelectricity element 93, such as shown in Fig. 9~Figure 11, it will be by as piezoelectricity Pyroelectricity electrode 93a, 93b in the rectangle for the specific length that a kind of pyroelectric ceramics of ceramics is constituted is to be parallel to each other State simultaneously sets and constitutes, and using above-mentioned a pair of of pyroelectricity electrode 93a, 93b being parallel to each other, is detected respectively to incident infrared light Light source distance, the variation of the difference of each detecting distance in the time and determines whether according to the rules to detect the movement of user There are users.

Such as shown in figure 12, pyroelectricity electrode 93a, 93b, it is defeated at its to be mutually connected in series in the form of antipolarity each other Side out is connected with the impedance transformation gate portion of the FET96 of (amplification is used) in the form of constituting source electrode tracker circuit.To, Thereby, it is possible to be effectively reduced be essentially high impedance pyroelectricity electrode 93a, 93b impedance, export effective voltage level Sensor signal Vpp.

Rg indicates the resistance value of the pyroelectric ceramics part of pyroelectricity electrode 93a, 93b, and Rs indicates the source for being connected to FET96 Source resistance between pole portion and Gnd, Vcc indicate the drain voltage for being applied to the drain portion of FET96.

Infrared light is incident to pyroelectricity electrode 93a, 93b, the temperature of the pyroelectric ceramics part of pyroelectricity electrode 93a, 93b When rising, spontaneous polarization is generated, generates charge (pyroelectric effect) corresponding with temperature rise on its surface.Moreover, should The electric current i that charge generates, flow to the resistance Rg of above-mentioned pyroelectric ceramics part, and stream can be controlled by generating at the both ends of resistance Rg Cross the grid voltage Rgi of the value of the leakage current Id between the drain electrode and source electrode of FET96.

The on state between the drain electrode and source electrode of FET96 is controlled using grid voltage Rgi, with the grid voltage The corresponding leakage current Id of the size of Rgi flows to source side from the drain side of FET96, and then leakage current Id flows through source resistance Rs。

As a result, at the both ends of source resistance Rs, such as shown in (L) or (R) of Figure 18, generate the output electricity of IdRs Vpp is pressed, the sensor signal of human body sensor MS is become.The voltage level of sensor signal Vpp, with correspond to The grid voltage Rgi's that the both ends of the resistance Rg of the part pyroelectricity electrode 93a, 93b of the gate electrode side of above-mentioned FET96 generate is big It is small, i.e. to the light quantity of the infrared light of pyroelectricity electrode 93a, 93b incidence and pyroelectric ceramics part generate electric current i size It is corresponding.

By corresponding with to the incident incident light quantity of above-mentioned a pair of of pyroelectricity electrode 93a, 93b difference being parallel to each other Sensor signal Vpp detects the distance of the light source to incident infrared light respectively, according to the rules each detecting distance in the time Whether difference changes to detect the activity of user (movement), and judgement is in defined corresponding position corresponding with above-mentioned electric cooker main body It is no to have user.Whether there is the judgement of user for example as shown in figure 20 in the defined corresponding position, by believing the sensor The microcomputer control unit 100 of number Vpp input side micro computer substrate 60B and automatically carry out.

When determining user in above-mentioned defined corresponding position, which makes to control power supply to operation Illuminating LED drive device 114 of the operation substrate circuit control device 111 of the supply state of substrate circuit, Operation switch etc. Movement supplies power supply to the operation substrate circuit of the operation panel portion 60 in non-power status (energy-saving mode), and makes By various Operation switch SW1~SW9 operation realize cook or the operation of heat insulation function setting, cancel, change etc. operation The illumination of function, above-mentioned each Operation switch SW1~SW9, which is shown, to be able to carry out, in addition, by making liquid crystal display panel drive dynamic control device 112 movements extinguish the backlight point for making the liquid crystal display panel 60A in OFF state in user not in defined corresponding position It is bright, meanwhile, when there is no user, the information of liquid crystal display panel 60A of the display in non-display state.

As a result, being constantly in the behaviour of the upper surface of the lid 2 of hidden state (opaque state) as Fig. 1 before Make each Operation switch or the liquid crystal display panel part of 60 part of panel, such as becomes bright as shown in Figure 2 and clearly illuminate, show State.On the other hand, in the case where being determined as no user, become its opposite control.

User can observe the display information of the liquid crystal display panel 60A of bright illumination, display by transparency window 60c as a result, And each Operation switch SW1~SW9 of operation panel 60 can be operated and carry out appropriate cook or the operation of heat insulation function is set Fixed, cancellation, change.Alternatively, it is also possible to be timed device reservation when standby mode of cooking under operation setting state confirmation, The confirmation of cook state or keeping warm mode, clock expression in heat preservation etc. for cooking.

Moreover, above-mentioned various operations, can only be realized automatically close to electric cooker main body by user, not need operation key Any manual operation such as opening operation, so very convenient.

In addition, in the case of that construction, be not limited only to previous such simple standby mode, as long as in short, with Family is not near electric cooker, in the case where both not needing to operate or do not need display, comprising that can save including clock display Or stop supply of the power supply to nearly all power consumption part, so energy-saving effect is very high.

In addition, the symbol 94 in Figure 12 indicates to enclose the monolithic IC of various electronic devices as described above.

The detection sensitivity and detection zone of human body sensor MS as described above, as described above, close with user The electric cooker main body, it is opposite with 60 face of operation panel of its upper surface part, and being located at can be suitable for the common operation operated On the basis of corresponding position, it is contemplated that it is set from the light quantity of the infrared light of the human body of user radiation, it therefore, can in the future for the time being The detection limit of the infrared light of position other than from it is excluded as interference.Therefore, if with original operation corresponding position User the corresponding infrared light of body temperature to being worth on the basis of the amount of incident of pyroelectricity electrode 93a, 93b, and to actually enter If being detected on the basis of the light quantity of infrared light, so that it may suitably detect the close of user, roughly correctly obtain above-mentioned Such reply.

But preferably in the case where such electric cooker, rear portion is leaned in the center upper portion of above-mentioned lid 2, such as The upper steam component 51 for being equipped with pressure regulation, offers pair of right and left steam port 51a, 51a on the steam component 51.Into When row is cooked (boiling maintains process), from the steam V of the steam port 51a, 51a blowout high temperature.Therefore, even if above-mentioned human body sensing The light-receiving surface of the acceptance part 90a of sensor MS for example (engraves plate 20 positioned at the upper surface than above-mentioned lid 2 as shown in Figure 7, Figure 8 Upper surface) lower position, if the upper surface (upper surface of inscription plate 20) of above-mentioned lid 2 is from there are the rear ends of steam component 51 Side towards the front end side 20b be it is flat if, then, the acceptance part 90a of above-mentioned human body sensor MS in the front-back direction by Optic angle θ a extends rearward, can detect the infrared ray of the steam V from above-mentioned steam port 51a, 51a, existing not can be carried out The problem of user appropriate detects.As a result, the transition as described above to energy-saving mode appropriate, releasing performance are hindered Hinder.

Therefore, in structure preferably, such as shown in Fig. 3, Fig. 8, firstly, the upper of above-mentioned lid 2 will be constituted The entirety of the above-mentioned 51 side closer to the top part 20a of steam component of ratio of the inscription plate main body 20 of surface element, is configured to towards before it The mode holding the side 20b and highly gradually decreasing declines the inclined surface (referring particularly to the structure of Fig. 8) for tilting regulation angle θ b, engraves plate In big part side (the timer preset switch SW1 by front end in the inclination angle of the inscription plate main body 20 as the decline inclined surface Near: referring to Fig. 2) the opening 20c of circular first light is formed, meanwhile, it is being located at the micro- electricity for being set to side below The coaxial parts on micro computer substrate 60B in brain substrate installation space 28 are arranged by above-mentioned acceptance part 90a and light receiving circuit portion The human body sensor MS that 90b is constituted.

Moreover, in addition to part corresponding with liquid crystal display panel 60A, being additionally provided with substrate cover on above-mentioned micro computer substrate 60B 29, the defined electronic component on above-mentioned micro computer substrate 60B is covered, in the above-mentioned human body with 29 side of micro computer substrate cover The acceptance part 90a of inductive pick-up MS and 20 the first light of side of above-mentioned inscription plate main body corresponding part of opening 20c coaxial, are opened Opening (the slightly larger diameter of the 20c that is open is used than the first light) 29a equipped with same circular second light.

Moreover, through this structure, forming the rule of above-mentioned human body sensor MS setting as shown in Figure 7 The concave part of depthkeeping degree, above-mentioned human body sensor MS are arranged in the form being accommodated in the concave part, can correctly only Detect the opening infrared light of 20c, 29a to acceptance part 90a incidence via above-mentioned first, second light.

Moreover, in this case, the 51 side close to the top part 20a of steam component of above-mentioned inscription plate main body 20, as described above, with rule Fixed angle downwards θ b declines from the front side of steam component 51 towards the front end side 20b to be tilted.Therefore, it is located at the inscription plate main body 20 Inclined surface part and be open above-mentioned first light opening 20c, such as shown in figure 8, its circular opening face with it is upper It states decline tiltangleθ b correspondingly to lean forward, with regard in the front-back direction for by light detection angle θ a, light central axis is also correspondingly From vertical direction skew back inclined downward θ b forwards.

As a result, no longer detect the steam component 51 of the part from the central portion rear end for being located at above-mentioned inscription plate main body 20 The infrared light of the steam V of steam port 51a, 51a blowout can carry out more accurate user's detection.

Moreover, in the case where the embodiment, as indicated in Fig. 1 and Fig. 2, above-mentioned human body sensor MS, first Significantly distance is left to electric cooker body front end side direction from steam port 51a, 51a of above-mentioned steam component 51, and then close Engrave plate main body 20 left side a side (left side of timer preset switch SW1) setting, with positioned at lid central portion rearward Hold setting the part steam port 51a, 51a, the left and right directions that is significantly staggered position (the deviation width a) in referring to Fig.1, by This, is arranged with the state of completely not corresponding biasing in the longitudinal direction.Therefore, the effect with above-mentioned tiltangleθ b etc. is matched It closes, is less also easy to produce error detection.

Further, in the case of this embodiment, in the above cases, pasted in the upper surface of above-mentioned inscription plate main body 20 (if coincidence) have constituted such as the synthetic resin material by PET (polyethylene terephthalate) close to film construct it is translucent Waterproof cover (have both inscription 20 surface of plate main body defencive function waterproof synthetic resin sheeting) 80.The waterproof cover 80, In the part opening 20c for the first light of above-mentioned inscription plate main body 20 being arranged on the left of front end, such as such as Fig. 7, Fig. 8 institute Show, with concave spherical surface shaped depressions in the opening 20c of first light, which will come from said external detection zone Infrared light efficiently optically focused, form the acceptance part 90a for making light sensation luminosity be incident to above-mentioned human body sensor MS well Optically focused concavees lens 80a.Moreover, thus, it is possible to the infrared light of wider range is made efficiently to be incident to above-mentioned human body sense In the concave part of 20 inside of inscription plate where the acceptance part 90a of inductive sensing device MS.

But the PET material for above-mentioned waterproof cover 80 crystallizes structure from based on it even if being configured to transparent or semitransparent From the point of view of dichroism made etc., efficiently infrared ray may not can be made to penetrate.Therefore, in order to improve the permeability of infrared ray, on Waterproof cover 80 is stated preferably to thinly form as far as possible, but if if excessively thin, then exist above-mentioned operation panel etc. it is non-illumination when (figure 1 state) hidden effect reduce, it is seen that Operation switch or LED illumination hole and unsightly, and inscription 20 part of plate main body is anti- The problem that protective function also reduces etc..

Therefore, in this embodiment, such as shown in figure 8, constituting are as follows: in the concave spherical surface for forming above-mentioned concavees lens 80a Cover part other than portion maintains to form the certain thickness of above-mentioned hidden effect or safeguard function preferentially on the other hand The special thickness thinning in concave spherical surface portion of concavees lens 80a, improves the transmitance of infrared ray.

In addition, at the same time, such as shown in figure 9, the part acceptance part 90a in the side human body sensor MS is equipped with vault The sensitive lens 91 of top-type shape, the sensitive lens 91 of the dome-shaped shape, consists of: as to 93 part of pyroelectricity element Infrared light concentrating, the high highly sensitive convex lens of boundling function works.The sensitive lens 91 of the dome-shaped shape, by vault Top-type light collecting part (such as by by the curvilinear lens of section triangle shape on concentric circles side by side it is multiple, make by each The lens for the infrared ray boundling that the light of a gable refraction is made up of the Fresnel lens of the curved face type of same focus Portion) the barrel 91b of 91a and its underpart side constitutes.Barrel 91b is formed on the inside of it and is embedded in as human body sensing biography The stage portion (large-diameter portion) of the basket portion periphery of the light receiving circuit portion 90b in the sensor main body portion of sensor MS, and high dimensional accuracy Ground is embedded in the basket portion periphery of the light receiving circuit portion 90b as the sensor main body portion.As shown, barrel 91b The size up and down of interior stage portion (large-diameter portion), and has the pyroelectricity element being made of above-mentioned a pair of pyroelectricity electrode 93a, 93b The size up and down of the isometrical tubular basket of 93 above-mentioned light receiving circuit portion 90b matches, by the two with the state of Fig. 9 just When really being fitted into, above-mentioned concavees lens can will be come from the part pyroelectricity electrode 93a, 93b of above-mentioned pyroelectricity element 93, setting The focal length of the ballpark boundling of the infrared light of 80a.

In addition, in the periphery surface side of barrel 91b, equipped with the side that comes from above for being set to 29 side of micro computer substrate cover The stage portion (large-diameter portion) of sensor grips 29a engaging, as described above, sensitive lens 91 is embedded in upper side, correctly Alignment focal length and the human body sensor MS itself that is arranged are reliably fixed, thus will not due to the activity such as vibration and The focal length for generating setting changes.

In addition, the part of the lower end side circumferential direction in the barrel 91b of above-mentioned 91 side of sensitive lens, is equipped with and is set to biography The label T-phase of the positioning of the part of the lower end side sensor main part, that is, acceptance part 90b circumferential direction accordingly positions same Label T, pass through and be mutually properly aligned with this two labels T, T-phase and tool that is mutually chimeric and being installed on micro computer substrate 60B There are three the setting unit of pin hole, the state that can be correctly directed at focal length is suitably set.In addition, thus, it is possible into Setting of the row in view of suitable light distribution characteristic.

By the energy of the infra-red-emitting of human body (infrared light supply) radiation, square it is in at a distance from pyroelectricity element 93 Inversely reduce.Therefore, it is the detection sensitivity for improving human body sensor MS, needs optically to amplify this infrared ray Energy.Therefore, as described above, when the concavees lens 80a of optically focused is arranged, in human body sense in the opening portion 20c in the first light When acceptance part 90a of inductive sensing device setting itself has the sensitive lens 91 of the light collecting part 91a of the dome-shaped of infrared ray boundling, The amplifying device that they are constructed as optical 2 sections works, and can effectively amplify the infrared ray radiated from human body Energy.As a result, the detection sensitivity of human body sensor MS improves.

In addition, as described above, the concavees lens 80a for being located at the opening portion part 20c of the first light is concave spherical surface and concave, Therefore, correspondingly, with the collector lens 91 of human body sensor side optically at a distance from become close, can be further improved optics Amplification degree.In addition, due to also being reduced the case where hindering object outside contact, so being not easy attachment damage or dirt, Ke Yigao Degree maintains the transmitance of infrared ray.Nor it is also easy to produce damaged equivalent damage.

In addition, the light collecting part 91a of the dome-shaped in above-mentioned 91 side of sensitive lens, except the phenanthrene of dome-shaped shape as described above It, can also be using the linear lens of multiple section triangle shapes side by side for example on concentric circles, so that logical other than alunite ear lens The light of each gable refraction is crossed by the Fresnel lens or thickness of the plane of same focus from peripheral part direction Increased common convex lens of center portion etc., may be implemented same effect.

According to structure as above, user's detection sensitivity of human body sensor MS can be improved as much as possible.But As described above, human body sensor MS employed in present embodiment is the sensor of thermoelectric type, moreover, releasing as heat Electric device 93, using the thermoelectric type sensor for the doublet type for having a pair of of pyroelectricity electrode 93a, 93b for being parallel to each other.At this In the case where kind of sensor, using above-mentioned two to be parallel to each other group pyroelectricity electrode 93a, 93b, detected respectively to incident infrared The distance of the light source (body of user) of light is detected the movement of user by the variation of the difference of each detecting distance, determined whether It has users.

To, such as shown in figure 15, by above-mentioned two groups of pyroelectricity electrodes 93a, 93b merely towards where user In parallel and when setting, the incident light quantity to the infrared ray of this two groups of pyroelectricity electrode 93a, 93b incidences is equal in the positive direction F, heat The temperature rising for releasing electroceramics part is also equal, and therefore, the electric current i for flowing through the resistance Rg of pyroelectricity electrode 93a, 93b is mutually supported Pin, will not generate the grid current of FET96, therefore, will not generate sensor signal Vpp (6 signal waveforms referring to Fig.1 (F)).Therefore, difference will not be generated on detecting distance detected, cannot detects the presence of user.Certainly, actual user Movement, in certain degree also with left and right movement therefore although issuing fraction of signal, be difficult to reach enough letters Number level, it is difficult to correctly be detected.This in parallel and is setting this two groups of pyroelectricity electrodes 93a, 93b towards left and right directions In the case where it is also identical, although in this case, from above-mentioned face side, rearwardly side direction or its opposite direction be can be realized Defined detection sensitivity, but the movement of the people from left to right or from right to left moved in parallel cannot be detected.

For this, under the setting state of pyroelectricity electrode 93a, 93b of Figure 15, such as shown in L, people from left direction to Right direction is mobile, infrared ray sequentially from the pyroelectricity side electrode 93b it is incident to the side pyroelectricity electrode 93a in the case where, such as schemed Shown in 16 signal waveforms (L), even if the incident light quantity to the infrared ray of pyroelectricity electrode 93b, 93a incidence is equal, and heat The temperature rising for releasing electroceramics part is also equal, and there are defined time difference, institutes in the timing due to generating charge on them To flow through the electric current i of different directions in the part pyroelectricity electrode 93b, 93a in the timing of infrared ray incidence respectively, pass through the electric current The voltage of i and resistance Rg control the grid current of FET96, generate sensor signal corresponding with respective incident light quantity Vpp。

In addition, under the setting state of pyroelectricity electrode 93a, 93b of Figure 15, such as shown in R, people from right direction to the left Direction is mobile, infrared ray sequentially from the pyroelectricity side electrode 93a it is incident to the side pyroelectricity electrode 93b in the case where, such as such as Figure 16 Signal waveforms (R) shown in, even if the incident light quantity to the infrared ray of pyroelectricity electrode 93a, 93b incidence is equal, and heat is released The temperature rising of electroceramics part is equal, and there are the defined time differences in the timing due to generating charge on them, so point Do not flow through the electric current i of different directions in the part pyroelectricity electrode 93a, 93b in the timing of infrared ray incidence, by electric current i and The voltage of resistance Rg controls the grid current of FET96, generates sensor signal Vpp corresponding with respective incident light quantity.

That is, it is found that as pyroelectricity element 93, using have a pair of of the pyroelectricity electrode 93a being parallel to each other, It is crosscutting above-mentioned each with the defined time difference in light source in the case where the thermoelectric type sensor of the doublet type as described above of 93b In the case where pyroelectricity electrode 93a, 93b, effective detection sensitivity can be realized, but the case where light source is moved parallel to Under, it can not achieve effective detection sensitivity.But the activity of user is various, by with above-mentioned specific directionality Sensor, effective detection sensitivity may not be can be improved.

Therefore, in the embodiment, such as shown in FIG. 13 and 14, it will be provided with a pair of of the pyroelectricity electrode being parallel to each other Each part pyroelectricity electrode 93a, 93b of the thermoelectric type sensor of the doublet type of 93a, 93b, with from positive direction to oblique The state that direction tilts 45 degree or so is set on micro computer substrate 60B.In this way, as shown in arrow in Figure 14, infrared ray from The incident F, infrared ray of above-mentioned face side rearwardly side direction (from back side side to face side direction) are from left side side direction to the right Incident L, infrared ray in the case where the right side to the left any movement of the incident R of side direction, light source (human body) all reliably with Time difference crosscutting each pyroelectricity electrode 93a, 93b (93b, 93a) are able to maintain that the range of the detection sensitivity of requirement to X-Y two Direction substantially extends.

In this case, for example as shown in FIG. 9 and 10, the people body induction sensor MS, in the following table of its sensor basket Thus face tool is arranged on the sensor on micro computer substrate 60B with corresponding pin hole there are three assembly pin P1~P3 Setting unit part.

Moreover, showing human body sensor MS from Figure 13, in micro computer in the case where structure preferably On substrate 60B, be arranged on relative to as heating part power supply IC98,98 clip liquid crystal display panel 60A farthest away from pair Position on linea angulata.Therefore, for detest heat influence human body sensor MS, micro computer substrate can be avoided as best one can The influence of heating part on 60A can further increase its detection accuracy.

As described in the embodiment, the existing human body sensor MS of setting detection user is able to detect defined The presence of user in corresponding region, in the case where side of the user not in electric cooker, by the operation panel portion of above-mentioned lid 2 60 Operation switch portion SW1~SW9 and liquid crystal surface plate portion 60A is automatically set to WAIT mode (the non-energized shape that power supply is closed State), consumption electric power is reduced as much as possible, on the other hand, in the presence of human body sensor MS detects user, WAIT mode before automatically releasing is able to carry out desired operation and display, should in the case where using the above structure How the control performance of setting and the releasing of WAIT mode, reliability reliably detect with the people's body induction sensor MS The presence of user, i.e. human body sensor MS user's detection sensitivity it is highly relevant.

As the existing human body sensor MS of above-mentioned detection user, it is considered as following various devices: makes Corresponding to body temperature from the infrared ray that the body of user (light source) radiates to acceptance part (pyroelectricity element) incidence, to detect regulation The infrared sensor of the existing thermoelectric type of the user of position；Have the other infrared rays hair different from the body of user Light portion (light emitting diode) and infrared ray acceptance part (phototransistor), by that will be put from infrared luminous part (light emitting diode) It penetrates and the infrared ray for contacting and reflecting with the body of user is provided with infrared ray acceptance part (phototransistor) light to detect Infrared sensor of the existing reflected light of the user of position by light type；Or the image detection mode using solid-state image pickup element People's detection sensor etc..

But in the case where infrared sensor of the above-mentioned reflected light by light type, not only need illumination region and acceptance part The two independent optical elements, but also need shine optical path and light-receiving optical path the two optical beam paths, it is at high cost and construct Also complicated, it is difficult to setting in the lid of the electric cooker more than limitation spatially.In addition, having used the image of solid-state image pickup element People's detection sensor of detection mode is necessarily at high cost.It is in the present embodiment, simpler using structure from such situation List and cost is also low, makes to detect regulation to acceptance part (pyroelectricity element) incidence with the infrared ray of the body light source of user The infrared sensor of the existing thermoelectric type of the user of position is constructed by the way that concavees lens are arranged on the optical beam path, is convex The optical amplifying device of the multistages such as lens construction, compensates the decaying of the infra-red-emitting energy from human body, or by mentioning The infrared light transmission of high light opening portion, as much as possible raising detection sensitivity.

In addition, in this case, pyroelectricity element as above-mentioned thermoelectric type sensor, such as shown in Fig. 9~Figure 14, Using with two groups of pyroelectricity electrodes 93a, 93b doublet type structure, by this two groups of pyroelectricity electrodes 93a, 93b respectively come The distance for detecting the light source (body of user) to incident infrared light, by the variation of the difference of each detecting distance come correctly The activity for detecting user, to reliably determine whether to have users.

In this case, furthermore, only by this two groups of pyroelectricity electrodes 93a, 93b merely existing for the user just Face direction in parallel and is set, or if offsetting from it the left and right directions of 90 degree of positions in parallel and setting, detection function only exists It works on any and set direction direction of crosscutting above-mentioned front-rear direction or left and right directions, therefore, the mobile side other than it It in the case where, is difficult to generate difference by the detecting distance that two groups of pyroelectricity electrodes 93a, 93b are detected, it is difficult to it is sensitive to improve detection Degree.

Therefore, in present embodiment, such as shown in FIG. 13 and 14, be parallel to each other two groups of pyroelectricity electrodes be will be provided with Each part pyroelectricity electrode 93a, 93b of the thermoelectric type sensor of the doublet type of 93a, 93b, with from positive direction to oblique Direction tilts 45 degree or so of state and is set on micro computer substrate 60B, as shown in arrow in Figure 14, in infrared ray from above-mentioned The incident F, infrared ray of face side rearwardly side direction (from back side side to face side direction) are from the incidence of left side side direction to the right L, infrared ray is in the case where the right side to the left any action of the incident R of side direction, and light source (human body) is all reliably with the time difference Crosscutting each pyroelectricity electrode 93a, 93b (93b, 93a) are able to maintain that the range of required detection sensitivity in two direction X-Y Substantially expand.

Therefore, mutually auxiliary with the detection sensitivity raising of above optical amplifying device etc. effect, it realizes practical enough Detection sensitivity.

The setting state of inclination sensor of the < in relation to lid portion and the structure > of the sensor

Further, in the present embodiment, on the basis of above-mentioned human body sensor MS, also such as Figure 17~Figure 19 Shown, the cell substrates 60C part setting for being attached to micro computer substrate 60B in above-mentioned lid 2 detects above-mentioned lid 2 The inclination sensor of opening and closing (covers and is opened and closed sensor) IS and constitutes, and prevents from using using the detection signal of inclination sensor IS The maloperation of soft-touch control part when the opening and closing operations lid 2 of family.

As described above, in the case of this embodiment, the operation of the operation panel 60 of above-mentioned 2 upper surface side of lid is opened It closes part and is formed as touch panel construction (soft-touch control construction).In this way, when using touch panel construction, it is only light by finger tip The membrane keyboard for touching soft-touch control portion, can be such that Operation switch part is turned on, and operation, input become very easy.

It but on the other hand, may be unintentionally in the simultaneously opening and closing operations of the lid 2 of not operation Operation switch originally The case where causing the finger of user to touch membrane keyboard.In this case, since user under any circumstance senses in human body sensing In the detection corresponding region of device MS, so human body sensor MS detects the presence of user, energy-saving mode is released, it can be to behaviour Make switch SW1~SW11 to be operated, can both be shown by the illumination that light emitting diode L1~L19 carries out membrane keyboard, it can also To carry out the illumination of liquid crystal display panel 60A by light emitting diode L21~L25.That is, generating the maloperation of Operation switch etc..

Therefore, in the present embodiment, the open and-shut mode that lid 2 is detected by inclination sensor IS, is at least uncapping Under state, even if human body sensor MS detects the presence of user, the operation key input of Operation switch can not be carried out, is prevented Only such maloperation input.

Such as shown in FIG. 17 and 18, inclination sensor IS, in the cell substrates for the longitudinal wall construction for being provided with battery E In the encapsulation 99 of the built in type of the square shape for the specific thickness installed on 60c, it is staggered 90 degree with the shape with the encapsulation 99 The state of position forms the shade activity space 99a of the small square shape of predetermined size.Firstly, empty in shade activity Between in 99a, be rotationally provided with the shade (rotary body) being made of the partially flat cylindrical body of the short defined diameter of axial length 99b。

Such as shown in figure 18, shade 99b encapsulates 99 rears forward according to corresponding with the open and-shut mode of lid 2 To rotation inclination, and the shade activity space 99a in the encapsulation 99 is freely rotated, and is located at the shade activity space Four parts Angle Position a, b, c, d of 99a.

On the other hand, the outside portion of at least three Angle Position a, b, d in aforementioned four Angle Position a~d of encapsulation 99, Such as it is configured with infrared light-emitting diode D in the part upper end side Angle Position a, in front end side, the part Angle Position b is configured with photoelectricity Transistor T1 is configured with phototransistor T2 in the part rear end side Angle Position d, is connected with electricity in their anode-side, collector Source Vcc is connected with electric current system and rations the power supply and hinders R, load resistance R1, R2 in ground side.

Therefore, in the case of such a construction, such as when above-mentioned shade 99b is located at the Angle Position position a, phototransistor By shading, output is to close by T1, T2；Then when being located at Angle Position b, phototransistor T1 is closing, phototransistor T2 is to open；In addition, phototransistor T1, T2 are to open when being located at Angle Position c；And then when being located at Angle Position d, light Electric transistor T1 is unlatching, phototransistor T2 is closing.Therefore, defeated by the unlatching of above-mentioned phototransistor T1, T2, closing The combination of V1, V2 out, it is possible to determine that the open and-shut mode of lid 2 as heeling condition, i.e. Figure 23 in the front-back direction.

Currently, the encapsulation 99 of above-mentioned inclination sensor IS is set as example as shown in figure 19 under the closed state of lid 2 Such light emitting diode D reaches state (5 degree or so of inclination angle, the shape of the Angle Position a arrival surface of Figure 18 of surface State) when, shade 99b is located at Angle Position c, and under the closed state of the lid 2, above-mentioned phototransistor T1, T2 are in unlatching State, output V1, V2 are H.Moreover, the output V1, V2 are the combined signal of H, as the closed state for indicating lid 2 Signal is entered the microcomputer control unit 100 of such as Figure 20.

Later, when lid 2 is opened, corresponding to the rotation of lid 2 rearward, Angle Position a and the portion light emitting diode D Divide and gradually tilted to horizontal direction, the part Angle Position d deviates to the lower side, and shade 99b is moved to Angle Position d from Angle Position c (state of 9 θ 1 referring to Fig.1).

Since the state, lid 2 is further opened, final to open to maximum open position θ 2 (than 90 degree slightly by preceding) When, above-mentioned light emitting diode D and Angle Position a, Angle Position c become approximate horizontal state and on the other hand become Angle Position b and reach Reach the state of underface to surface, Angle Position d, shade 99b stops in the part Angle Position d, phototransistor T2 is closed It closes.

As a result, phototransistor T1 is to open, output V1 is H, and phototransistor T2 is to close, and output V2 is L.And And the combined signal that output V1 is H, output V2 is L, as testing signal of uncapping, such as shown in figure 23, with above-mentioned people The output signal Vpp of body induction sensor MS is entered microcomputer control unit 100 together, carries out above-mentioned operation panel 60 The control that the energy-saving mode of soft-touch control portion and liquid crystal display panel 60A, energy-saving mode release.

As a result, being reliably determined as according to above structure, such as in the testing result based on inclination sensor IS In the case that lid 2 is closed, the testing result based on above-mentioned human body sensor MS can in the case where having users The operation of operation portion and the display of display unit are carried out, operation appropriate, setting can be carried out.

On the other hand, at least when inclination sensor IS detects the opening of lid 2, even if human body sensor MS is examined The presence of user being measured, can also make the testing result of inclination sensor IS preferential, being controlled not can be carried out aforesaid operations portion Operation and display unit display energy-saving mode, be able to carry out desired control: not can be carried out operation, setting etc..

Control of the < in relation to the WAIT mode with the Operation switch portion in the relationship of the detection function of human body sensor >

As above-mentioned, in the case where being equipped with human body sensor MS as above, there is also a little problems, one is The problem of insensitive region of the people's body induction sensor.

That is, the human body sensor MS of above-mentioned infrared mode, from its characteristic for, temperature-dependent characteristics are high, quilt The infrared ray of defined temperature or more is inputted, and detects the presence of people according to the variation of its input direction.Moreover, because institute Detection is people, so the defined temperature of the above-mentioned infrared ray that should be detected, certainly on the basis of the body temperature of people, and to be based on people Body temperature radiation infrared ray input quantity on the basis of.

But the body temperature of the people is 36~37 degree or so of lower temperature, in the region that the midsummer of summer or temperature are high, Atmosphere temperature around the sensor portion of above-mentioned human body sensor MS is risen to sometimes with the body temperature of people on an equal basis or more than it Temperature.Then, it is entered the infrared ray amount of human body sensor MS, cannot distinguish between due to ambient temperature or due to coming From the radiation of user's body, there are problems that not can be carried out correct people's detection.In addition, the atmosphere temperature is not always certain, i.e., Make in one day, the morning and afternoon also have variation have the case where wind indoors and without wind in the case where, condition is not yet Together.

It is such as above-mentioned in addition, above-mentioned human body sensor MS, by having sensitive lens 91 and will be from external infrared light It the acceptance part 90a of optically focused and receives the infrared light by acceptance part 90a optically focused and exports the light receiving circuit portion 90b structure of electric signal At making to be selected as by the incident infrared light of the sensitive lens of acceptance part 90a 91 by infrared filter 92 preset After the light of band domain, collect in 93 part of pyroelectricity element in light receiving circuit portion 90b, will with it is defeated from 93 part of pyroelectricity element The corresponding voltage signal of light income out carries out impedance transformation, exports after the voltage level as defined in being enlarged into.

Above-mentioned pyroelectricity element 93, such as a pair of of the heat being made of the pyroelectric ceramics of one kind as piezoelectric ceramics is released Electrode 93a, 93b are with the state that is parallel to each other and set and constituted, using above-mentioned a pair of of the pyroelectricity electrode 93a being parallel to each other, 93b detects the distance of the light source to incident infrared light respectively, and the variation of the difference of each detecting distance in the time comes according to the rules The movement of user is detected, and determines whether there is user.

Therefore, necessarily there is the limitation of incidence angle in the circumferential direction in 91 part of sensitive lens of above-mentioned acceptance part 90a, separately Outside, the infrared ray introducing port 20c which is also formed on inscription 20 part of plate main body of 2 upper surface of lid is passed to human body sensing The opening diameter and depth of sensor MS is limited.

As a result, will be outside the incidence angle of the people's body induction sensor MS such as side portion of such as electric cooker main body When non-detectable region operates Operation switch SW1~SW11 on operation panel 60, human body sensor MS can not be examined The presence of user is surveyed, and above-mentioned WAIT mode (energy-saving mode) cannot be released, therefore, even if generating on touch operation panel 60 The part Operation switch SW1~SW11 the problem of can not being operated.

In addition, as above-mentioned, in the case where being equipped with human body sensor MS on lid 2, from steam component (pressure regulation group Part) 51 blowouts high temperature " meal thin rice gruel " flow into above-mentioned inscription plate main body 20 infrared ray introducing port 20c upper surface (concave part), Although not having users, the state that also human body sensor MS can be made to detect.In addition, after cooling, " meal thin rice gruel " The upper surface (concave part) of infrared ray introducing port 20c is covered, there is also sensitivity for making human body sensor MS itself as a result, The problem of reducing, and reducing detection function.

Embodiments of the present invention, in order to solve equipped in the technical task in the case where this human body sensor MS , particularly atmosphere temperature around the former sensor portion the problem of being in the case where the body temperature of people or more and constitute, in people In the case that atmosphere temperature around the sensor portion of body induction sensor MS is the body temperature of people or more, with human body sensor The presence or absence of the detection input of MS is unrelated, at least has the operation panel 60 of multiple Operation switch SW1~SW11 with operation (touch) Any one or more of Operation switch SW1~SW11 be condition, release the above-mentioned of above-mentioned multiple Operation switch SW1~SW11 Each Operation switch SW1~SW11 is controlled as that the display and movement of setting, input can be operated by WAIT mode (energy-saving mode) State (energized state that light emitting diode L1~L19 lighted, can control Fig. 2 of input).

The flow chart of Figure 21 indicates above-mentioned control method.In the control method, firstly, the control of Figure 20 of the electric cooker Power outlet shown in circuit processed is connect with AC power supplies, dynamic starting control to the timing of each power circuit of Figure 20 supply power supply Make.

If starting to control, it is defeated that the detection from above-mentioned human body sensor MS is determined whether there is in step S1 first Enter.Human body sensor MS, when user is in the defined detection zone of human body sensor MS, detection with from the use The corresponding infrared ray amount of body temperature of the body radiation at family, generates and inputs to the detection of the first microcomputer control unit 100A, no In these cases, then detection input is not generated.Whether there is or not the judgements of the detection input of the people's body induction sensor MS, with defined Control period repetition.

In addition, human body sensor MS, in the indoor temperature and human body sensor MS for placing the electric cooker In the case that test object, that is, user body temperature is same or the fever than user, also with user there are the case where in the same manner as, can Detection input, but this movement due to being not accompanied by heat source can be generated, thus it is very uncertain, not necessarily always it is correctly created inspection Survey input.

Therefore, in the judgement without the detection input (NO) of human body sensor MS herein, existing placement electricity meal Test object, that is, user body temperature of the indoor temperature and human body sensor MS that stew is same or fever than user Situation, also having not is such situation.

The judgement the result is that the detection without human body sensor MS input and in the case where being determined as NO, into connecing Step S2 determine from when initial NO determines after the connection of above-mentioned AC power supplies for example whether by defined setting time " 20 Second ".The judgement as a result, when without " 20 seconds ", be determined as NO, again return to above-mentioned step S1 input determine, The presence or absence of the detection input for determining above-mentioned human body sensor MS, in the case where NO, is again introduced into step S2, determines " 20 The process of second ".Above-mentioned acts of determination is repeated up to by above-mentioned " 20 seconds ".The defined setting time " 20 seconds ", in the electricity meal Stew in cooking, timer preset cook in, timer preset determine in, the medium next switch that do not need of heat preservation operates Standby mode and be possible to that operation setting but appointing currently without the operation standby mode for carrying out any operation will be carried out It is carried out in the case where one state.

The certain period judgement in, passing through the setting time " 20 seconds ", and be determined as the feelings of YES in step S2 Under condition, step S3 is subsequently entered, is normally carried out the judgement whether above-mentioned lid 2 closes first.The judgement as a result, in NO Lid 2 open in the case where, the acts of determination for the S1~S3 that repeats the above steps, until lid 2 close.

On the other hand, since initially lid 2 just close or be initially switched on but cover lid 2 halfway and be closed , at least when have passed through " 20 seconds " after above-mentioned control starts when 2 pent YES of lid, travel further into step S4, determine Whether the detection temperature of above-mentioned outer air-temperature sensor S2 is defined set temperature corresponding with the body temperature of user or more.And And in the case where it determines result for NO, due to the atmosphere temperature ratio around the sensor portion for human body sensor MS The body temperature of people is low, human body sensor MS can normally detect user there are the case where, therefore, subsequently enter step S5, carry out current state whether be not in cooking, timer preset cook in, timer preset determine in, heat preservation it is medium Control input operation setting after standby mode, not yet carry out any control input operation setting " operation standby in " Determine.As a result, subsequently entering step S6 for " the operating in standby " of YES, using above-mentioned touch detection Second microcomputer control unit 100B is moved to WAIT mode (non-through power mode), stops operating aforesaid operations switch S1~S11 The energization of input circuit and LED for illumination L1~L20.Moreover, the preparation state setting of step S7 is maintained this Energy saving preparation state under " WAIT mode (non-through power mode) ", up to there is normal human body sensor input to be later Although only or until for expected the case where not having the input of normal human body sensor but to Operation switch SW1~ Until SW11 has touch operation, consumption electric power is saved as much as possible.

On the other hand, in the judgement of step S5, in NO, current state " are not operated in standby ", cooked, determine When device reservation cook in, timer preset determine in, " the common standby shape after the medium control input operation setting of heat preservation In the case where state ", it is directly entered step S7, sets (maintenance) as the preparation state under the common standby mode.

In this way, there is no for example the detection input of human body sensor MS, lid 2 to close more than " 20 seconds ", outer temperature The detection temperature of sensor S2 is lower than the body temperature of people, and multiple Operation switch SW1~SW11 also not yet carry out the " behaviour of any operation Make in standby " in the case where, stop the operation input circuit and LED for illumination to multiple Operation switch SW1~SW11 The energization of L1~L19 realizes that the small operation of consumption electric power prepares state (Fig. 2) as much as possible.

On the other hand, even if so that touch detection with the second microcomputer control unit 100B is moved to WAIT mode (non-this Powered-on mode) and stop leading to aforesaid operations switch S1~S11 operation input circuit and LED for illumination L1~L19 Under the operation preparation state of the energy-saving mode of electricity, also as shown in step S8~S12, is determined as follows with the defined period: being The no detection input for having human body sensor MS, whether lid 2 closes, whether the detection temperature of outer air-temperature sensor S2 is people Body temperature more than, whether be during operation is standby, current operation prepare state whether be common operation preparation state, whether be LED for illumination L1~L19 of multiple Operation switch SW1~SW11 is all extinguished, consumption electric power section as small as possible Can operation preparation state under mode, whether be under WAIT mode of the touch detection with the second microcomputer control unit 100B Operate preparation state.

As a result, have human body sensor MS detection input in the case where (YES), without step S9~ The judgement of S12, and step S17 is skipped to, it carries out current operation and prepares whether state is the second micro computer control of touch detection The judgement of operation preparation state under the WAIT mode of unit 100B.As a result, it is to touch inspection that current operation, which prepares state, In the case where the operation preparation state under the WAIT mode of second microcomputer control unit 100B of survey (YES), step is continued through After rapid S18 releases the WAIT mode, above-mentioned steps S1 is returned, the judgement of above-mentioned step S1~S5 and the place of step S6 are carried out Reason；Carry out the non-tactile detection normal mode of the operation preparation state under the WAIT mode of the second microcomputer control unit 100B Under preparation state setting or touch detection under the WAIT mode of the second microcomputer control unit 100B operation prepare shape The setting of state.

On the other hand, in the WAIT that the judgement of step S17 is non-tactile the second microcomputer control unit 100B of detection In the case where preparation state, that is, NO judgement of the normal mode of operation preparation state under mode, return in such a state Above-mentioned steps S1 carries out the judgement of above-mentioned step S1~S5 and the processing of step S6.

In addition, with above-mentioned difference, in the case where the detection of no human body sensor MS input (NO in step S8), Then it enters step S9 and carries out the judgement whether lid 2 closes, and only in the case where lid 2 is not turned off (in step S9 NO), S17 is entered step, carries out whether current preparation state is the second microcomputer control unit 100B of touch detection The judgement of operation preparation state under WAIT mode.As a result, current preparation state is that touch detection is micro computer controlled with second In the case where operation preparation state under the WAIT mode of unit 100B processed (YES), continues through step S18 and release the WAIT mould After formula, above-mentioned steps S1 is returned, carries out the judgement of above-mentioned step S1~S5 and the processing of step S6, non-tactile detection is carried out and uses Under the WAIT mode of second microcomputer control unit 100B operation preparation state common operation prepare state setting or The setting of operation preparation state of the touch detection under the WAIT mode of the second microcomputer control unit 100B.

On the other hand, prepare in operation of the non-touch detection under the WAIT mode of the second microcomputer control unit 100B In the case where the preparation state of the normal mode of state (NO), above-mentioned steps S1 is returned to such state, carries out above-mentioned step The rapid judgement of S1~S5 and the processing of step S6.On the other hand, in the feelings of the detection input of no the people's body induction sensor MS Under condition, and in the case where be determined as that lid 2 is turned off in the judgement of step S9 (YES), step S10 is further moved to, is carried out The detection temperature of above-mentioned outer air-temperature sensor S2 whether be the body temperature of people or more judgement.As a result, being passed in above-mentioned outer temperature The detection temperature of sensor S2 is to travel further into step S14 in the case where the body temperature of people or more (YES), carry out current preparation Whether state is that all extinguishing, consumption electric power are use up by LED for illumination L1~L20 of multiple Operation switch SW1~SW11 May operation preparation state under small energy-saving mode, whether be the second microcomputer control unit 100B of touch detection The judgement of WAIT mode, in the case where not being the WAIT mode for the processing that have passed through above-mentioned step S6 (NO), further S16 is entered step, determines whether either one or two of above-mentioned multiple soft-touch control SW1~SW11 are operated, i.e., whether there is or not touch key input Judgement.It is that it determines the result is that there is the YES of the input of membrane keyboard in the case where, into above-mentioned step S17, carry out current Whether preparation state is operation preparation shape of the above-mentioned touch detection under the WAIT mode of the second microcomputer control unit 100B The judgement of state.As a result, current preparation state is the WAIT mode of the second microcomputer control unit 100B of touch detection Under operation preparation state in the case where (YES), continue through after step S18 releases the WAIT mode, return to above-mentioned steps S1, The judgement of above-mentioned step S1~S5 and the processing of step S6 are carried out, the second microcomputer control unit of non-tactile detection is carried out Second micro- electricity of setting or touch detection of the preparation state of the normal mode of operation preparation state under the WAIT mode of 100B The setting of operation preparation state under the WAIT mode of brain control unit 100B.

On the other hand, in the WAIT that current preparation state is the second microcomputer control unit 100B of above-mentioned touch detection In the case where operation preparation state under mode (in the case where being YES in the judgement of above-mentioned steps S14), step is initially entered S15 determines above-mentioned steps S16's after relieving WAIT mode of the touch detection with the second microcomputer control unit 100B Whether either one or two of above-mentioned multiple soft-touch control SW1~SW9 are operated, i.e., whether there is or not touch key input.

That is, being above-mentioned touch in the case where entering step S9, step S10, step S14, step S15 from step S8 Detection prepares state with the operation under the WAIT mode of the second microcomputer control unit 100B, moreover, nobody's body-sensing inductive sensing The detection of device MS inputs, and lid 2 is closed, and is set to the outer air-temperature sensor S2 of the temperature of the detection room air of electric cooker main body Detected value be the body temperature of people or more temperature, even if user is close, also cannot to expect that human body sensor MS's is normal The state of people's detection function above-mentioned touch detection cannot be released by the people's body induction sensor MS in such a state With the WAIT mode of the second microcomputer control unit 100B, there are user want to operate above-mentioned multiple Operation switch SW1~SW9 without A possibility that can be carried out operation.

Therefore, as above-mentioned, even if in the case where being inputted in step S15 without the detection of human body sensor MS, The above-mentioned touch detection of the compulsory commutation WAIT mode of the second microcomputer control unit 100B, makes Operation switch SW1~SW11's Operation is able to carry out.On this basis it is possible to carry out the behaviour for whether having actual Operation switch SW1~SW11 in step S16 Work, the judgement for whether having key input.

Moreover, it is that the key input determines the result is that there is the YES of the input of a certain membrane keyboard in the case where, into above-mentioned step Rapid S17 carries out whether current preparation state is WAIT mould of the above-mentioned touch detection with the second microcomputer control unit 100B The judgement of operation preparation state under formula.As a result, current preparation state is the second micro computer control of above-mentioned touch detection In the case where operation preparation state under the WAIT mode of unit 100B (YES), continues through step S18 and release the WAIT mode Afterwards, above-mentioned steps S1 is returned, the judgement of above-mentioned step S1~S5 and the processing of step S6 are carried out.

On the other hand, different from the situation, in the case where entering step S10 from above-mentioned steps S8, it is set to electric cooker The detected value of the outer air-temperature sensor TS2 of the temperature of the detection room air of main body than people body temperature, as long as user is close, human body In the case where being NO in the step S10 for people's detection function that inductive pick-up MS can bring into normal play, it is directly entered step S11, determine current preparation state whether be not in cooking, during timer preset is cooked, timer preset determine in, heat preservation During the operation for not operating standby mode of the preparation state of medium normal mode prepares.As a result, the current preparation shape of NO During state is in cooking, timer preset is cooked, timer preset determine in, heat preservation it is medium do not need Operation switch SW1~ In the case where the operation of SW11, the common preparation state that has been carried out the settings such as information of cooking, above-mentioned step is directly returned The preparation state of rapid S7.

On the other hand, not above situation, but be the behaviour for the operation for needing soft-touch control that information etc. is not set of cooking In the case where the YES for making the preparation state in standby, further determine whether the preparation state is that have passed through above-mentioned steps S6 The WAIT mode of the second microcomputer control unit 100B of the touch detection of processing.As a result, YES's have passed through above-mentioned steps In the case where the WAIT mode of the processing of S6, if user's detection function of above-mentioned human body sensor MS be it is normal, The preparation state of above-mentioned step S7 is directly returned to, judgement, processing after the S8 that repeats the above steps with the defined control period.

On the other hand, be determined as in the judgement of the step S12 NO, current preparation state not have passed through it is above-mentioned When the WAIT mode of the processing of step S6, travel further into step S13, with the above-mentioned step S6 the case where in the same manner as, setting All to extinguish LED for illumination L1~L20 of above-mentioned multiple Operation switch SW1~SW11, consumption electric power is as far as possible Operation preparation state under small energy-saving mode moves to the touch detection WAIT mode of the second microcomputer control unit 100B Operation standby mode under preparation state, and with the defined control period repeat above-mentioned judgement, handle.

As above, in the embodiment of the present patent application, with following for condition: the gas around human body sensor MS The detection temperature of the outer air-temperature sensor S2 of atmosphere temperature, the i.e. temperature of detection room air is lower than the body temperature of people (in step S4 NO), it is able to carry out in the state of the detection of normal people, without the state (step of the detection input of human body sensor MS NO in S1) continue defined more than the time (such as 20 seconds) (YES in step S2), and the lid 2 of electric cooker main body closes (step YES in S3), so in cook, timer preset cook in, timer preset determine in, heat preservation it is medium in addition to operating surface Multiple Operation switch SW1~SW11 on plate without the key operation of any operation it is standby in (YES in step S5), setting are as follows: Above-mentioned touch detection is set to move to WAIT mode with the second microcomputer control unit 100B, by multiple behaviour on aforesaid operations panel 60 The operation input circuit for making switch SW1~SW9 is set as closing, while LED for illumination L1~L20 being made all to extinguish, disappear Operation under power consumption power energy-saving mode as small as possible prepares state.Therefore, energy-saving effect improves.

On the other hand, the touch detection is with the WAIT mode of the second microcomputer control unit 100B, due to such as it is above-mentioned that The indoor temperature of sample is lower than the body temperature of people, and above-mentioned human body sensor MS can reliably detect the existing state of user, Therefore, even if being set under the energy-saving mode of WAIT mode for the above-mentioned touch detection with the second microcomputer control unit 100B Key operation prepare state, when above-mentioned human body sensor MS detect user there are when, can also release the touching at once The WAIT mode (operation under energy-saving mode prepares state) for touching the second microcomputer control unit 100B of detection, carries out multiple behaviour Make operation, the input of switch SW1~SW11.Therefore, it can be realized the behaviour of energy-efficient performance and necessary Operation switch SW1~SW11 The property made gets both.

But as above-mentioned, there are problems that insensitive region in above-mentioned human body sensor MS, such as it is contemplated that: When more than the body temperature of the high intelligent of atmosphere temperature around the sensor portion of human body sensor MS, although user does not exist, A possibility that detecting someone under the atmosphere temperature and releasing energy-saving mode, can not work there are hard-won power saving function.

Moreover, the above are possibility, existing there is a situation where also have not that there is a situation where actually user will grasp as a result, The case where operating switch SW1~SW11 can not provide by the way that the human body as infrared source is mobile before the deadline Distance and reliably detect the presence of people.Therefore, as above-mentioned, when temperature indoors is increased to the body temperature of people or more, for Above-mentioned human body sensor MS cannot expect normal people's detection function, even if there is detection to input, it is real for can not distinguishing it Caused by the atmosphere temperature being only due around human body sensor MS on border by user's operation, also is high.

Therefore, such as above-mentioned in the embodiment of the present patent application, it is to open in AC power supplies, nobody's body-sensing inductive sensing The state of the detection input of device MS continue 20 seconds it is above in the case where, closed with lid 2 and indoor temperature than people body temperature It is low, in cook, timer preset cook in, timer preset determine it is medium in addition to key operation it is standby in be condition, must So it is set as above-mentioned WAIT mode.Under the WAIT mode setting state, such as above-mentioned, temperature indoors is increased to the body temperature of people When above, detect that the indoor temperature is increased to the body temperature of people or more (step S10), regardless of whether there is above-mentioned human body sensing to pass The detection of sensor MS inputs, the WAIT mode (step of the second microcomputer control unit 100B of the above-mentioned touch detection of compulsory commutation S15), later, do not inputted by the detection of above-mentioned human body sensor MS, and by multiple Operation switch SW1~SW11 Either one or two of touch or touch to multiple soft-touch controls, make under normal conditions due to there is no human body sensor MS's The operation that detection inputs and is maintained multiple Operation switch SW1~SW11 of invalid state is possibly realized, and it is more to be able to carry out this The judgement (step S16) of the operation input of a Operation switch SW1~SW11.

As a result, applying for the electric cooker of embodiment according to the present invention, the atmosphere temperature of surrounding is than as original inspection Survey object people body temperature low (NO in step S10) and human body sensor MS can normally detect people there are the case where Needless to say, the atmosphere temperature of surrounding be up to body temperature as the people of original test object or more (YES in step S10) and In the presence of human body sensor MS normally cannot detect people, without dependent on human body sensor MS's Detection input, and the touch operation based on user to Operation switch SW1~SW11, reliably lift WAIT mode, make necessary Operation, the input of Operation switch SW1~SW11 is possibly realized.

Therefore, in the case where being equipped with human body sensor MS, can not damage original suitable operation sense and into It exercises and is set with the suitable input cooked, keep the temperature information of multiple Operation switch SW1~SW11.

In addition, in this case, the time as defined in the finger interval occasionally there are user connects in above-mentioned WAIT mode release The case where contacting multiple Operation switches continuously.In this case, the first microcomputer control unit 100A detects finger most of course The touch operation to membrane keyboard of the first time just contacted releases WAIT mode, and allows from secondary touch operation Operation input, but in the case where the time for the first time between secondary touch operation is too short (such as 15 seconds or less), depending on For dual operation when not operation inputs and is WAIT mode release, it is impermissible for inputting.

1-1) related variation 1

Then, Figure 22 indicates to sense with the human body sensing of the structure of the variation 1 of the electric cooker of above-mentioned first embodiment The control method of WAIT mode in the relationship of the detection function of device.

Above-mentioned human body sensor MS, as above-mentioned by having sensitive lens 91 and will be from external infrared light optically focused It acceptance part 90a and receives by the infrared light of acceptance part 90a optically focused and exports the light receiving circuit portion 90b of electric signal and constitute, make to lead to The infrared light for crossing 91 incidence of sensitive lens of acceptance part 90a is selected as preset band domain by infrared filter 92 Light collects in 93 part of pyroelectricity element in light receiving circuit portion 90b, by with the light that is exported from 93 part of pyroelectricity element It measures corresponding voltage signal and carries out impedance transformation, exported after the voltage level as defined in being enlarged into.

Above-mentioned pyroelectricity element 93, such as a pair of of the heat being made of the pyroelectric ceramics of one kind as piezoelectric ceramics is released Electrode 93a, 93b are with the state that is parallel to each other and set and constituted, using above-mentioned a pair of of the pyroelectricity electrode 93a being parallel to each other, 93b detects the distance of the light source to incident infrared light, and the variation of the difference of each detecting distance in the time according to the rules respectively It detects the movement of user, and determines whether there is user.

Therefore, in 91 part of sensitive lens of above-mentioned acceptance part 90a, it is inevitable in the circumferential direction have the limitation of incidence angle, in addition, The infrared ray introducing port 20c that the incidence angle is also formed on inscription 20 part of plate main body of 2 upper surface of lid is sensed to human body sensing The opening diameter and depth of device MS is limited.

As a result, such as will be the side portion from electric cooker main body, outside the incidence angle of the people's body induction sensor MS When the Operation switch SW1~SW11 being unable on detection zone operation operation panel 60, human body sensor MS can not be detected The presence of user cannot release WAIT mode (the energy saving mould of the second microcomputer control unit 100B of above-mentioned touch detection Formula), therefore, leading to the problem of can not be operated even if the part Operation switch SW1~SW11 on touch operation panel 60 (Second Problem described in above-mentioned first embodiment).

Therefore, in the case where the structure of the variation 1, such as shown in the flow chart of Figure 22, it is unlatching, does not have in AC power supplies In the case where state continuation 20 seconds or more for having the detection input of human body sensor MS, with the closing of lid 2 and indoor gas Temperature is lower than the body temperature of people, in cook, timer preset cook in, timer preset determine in, heat preservation it is medium in addition to key It operates in standby as condition, it is necessary to which above-mentioned touch detection is set as WAIT mode with the second microcomputer control unit 100B.

Moreover, under the WAIT mode setting state, (the step S8 in the detection input of no human body sensor MS The case where middle NO), it detects that the indoor temperature is increased to the body temperature of people or more (step S10), that is, considers above-mentioned human body sense The detection of inductive sensing device MS inputs unsuitable situation, the second microcomputer control unit 100B of the above-mentioned touch detection of compulsory commutation WAIT mode (step S15) do not inputted later by the detection of above-mentioned human body sensor MS, and by multiple behaviour Make the touch of either one or two of switch SW1~SW11 or the touch to multiple switch, makes under normal conditions due to there is no human body sensing The operation that the detection of sensor MS inputs and is maintained multiple Operation switch SW1~SW11 of invalid state is possibly realized, energy Enough carry out the judgement (step S16) of the operation input of multiple Operation switch SW1~SW11.So far control content and above-mentioned the The control content of the flow chart of Figure 21 in one embodiment is identical.

But in the case where the variation 1, in the presence or absence of the detection input of human body sensor MS of above-mentioned steps S8 It is NO in judgement, i.e. the presence that user is not detected in human body sensor MS is NO, i.e. human body in the judgement of step S10 Atmosphere temperature around inductive pick-up MS is not the body temperature of people or more, and human body sensor MS can normally detect use In the presence of family, with current state be cook in, timer preset cook in, timer preset determine in, heat preservation In other than key operation it is standby in (YES in step S11), for above-mentioned WAIT mode (YES in step S12) be condition, with judgement In the same manner for situation (YES in step S10) that the atmosphere temperature around human body sensor MS is the body temperature of people or more, enter Step S15, the WAIT mode of the second microcomputer control unit 100B of the above-mentioned touch detection of compulsory commutation, later, not by upper It states the detection input of human body sensor MS, and passes through touch to either one or two of multiple Operation switch SW1~SW11 or right The touch of multiple switch makes to be maintained invalid shape due to not having the detection of human body sensor MS to input under normal conditions The operation of multiple Operation switch SW1~SW11 of state is possibly realized, and is able to carry out the operation of multiple Operation switch SW1~SW11 The judgement (step S16) of input.Other structures are identical with the structure of the flow chart of Figure 21 of above-mentioned first embodiment.

As a result, according to the structure of the variation 1, although being the atmosphere temperature of surrounding than original test object, that is, people Body temperature low (NO in step S10), human body sensor MS can normally detect people there are the case where, but due to electric meal Side or rear of pot main body etc., user will operate outside the detectable region of human body sensor MS, thus, to the greatest extent In the presence of the function of pipe human body sensor MS normally cannot but detect user, touch detection use is reliably lifted The WAIT mode of second microcomputer control unit 100B is not inputted later by the detection of above-mentioned human body sensor MS, and By the touch to either one or two of multiple Operation switch SW1~SW11 or to the touch of multiple switch, make under normal conditions due to There is no the detection of human body sensor MS to input and be maintained the operation of multiple Operation switch SW1~SW11 of invalid state It is possibly realized, is able to carry out the judgement (step S16) of the operation input of multiple Operation switch SW1~SW11.

Therefore, in the case where being equipped with human body sensor MS, can not also damage original operation sense appropriate and Set using the input appropriate cooked, keep the temperature information of multiple Operation switch SW1~SW11.

1-2) related variation 2

In addition, as above-mentioned, in the case where lid 2 is provided with human body sensor MS, from the lid 2 of electric cooker main body " the meal thin rice gruel " of high temperature of steam port 51a, 51b blowout of steam component 51 flow into the infrared ray of above-mentioned inscription plate main body 20 and import The upper surface (concave part) of mouthful 20c, although user is not present, the state that detects human body sensor MS.And And later, due to the upper surface (concave part) of cooling " meal thin rice gruel " covering infrared ray introducing port 20c, thus in the presence of human body is made The problem of sensitivity of inductive pick-up MS itself reduces and reduces detection function (third described in foregoing first embodiment Problem).

Therefore, under such circumstances, also with above-mentioned Figure 21, Figure 22 the case where in the same manner as, with human body sensor MS Detection function distinguish, by the touch operation to Operation switch SW1~SW11, in the inspection of no human body sensor MS In the case where surveying input, the touch detection WAIT mode of the second microcomputer control unit 100B can be reliably lifted, in this way, In the case where the attachment due to " meal thin rice gruel " causes the detection function of human body sensor MS to lose reliability, by more The touch of either one or two of a Operation switch SW1~SW11 or touch to multiple switch, can also restore multiple Operation switches The operating function of SW1~SW11 is able to carry out the operation input carried out by the operation of multiple Operation switch SW1~SW11 Judgement.

That is, in this case, for the above-mentioned reservation switch SW1 that cooks, the switch SW2 that cooks, cancelling switch SW3, sound instruction Switch SW7, the heat preservation selection switch of switch SW8 this 5, respectively at its center part only one light emitting diode L1, L2 of setting, L3, L7, L8, can also such as hour at the time of menu selection switch SW5 (return) SW6 (advance) and clock and timer In SW9 minutes configuration switch SW10 of configuration switch, for above-mentioned SW5, SW6, SW9, SW10, corresponding with each text importing Part light emitting diode L5, L6, L9, L10 on the basis of, also between above-mentioned SW5 and SW6, between SW9 and SW10 " " part is also provided independently from light emitting diode L12, L13 and is shown.In addition, selecting switch SW4 and complete in firepower size In the case where at level set switch SW11, in addition to above-mentioned SW4, SW11 each central portion setting light emitting diode L4, Except L11, it is respectively equipped with multiple groups (3 groups) light emitting diode L14~L16, L17~L19 for indicating its setting level.

It is used in addition, being additionally provided with the backlight integrally illuminated to liquid crystal panel on the substrate of above-mentioned liquid crystal display panel 60A Light emitting diode L20~L24.

In addition, the state of Figure 23 indicates that light emitting diode L1~L19, the L20~L24 of the operation panel 60 all extinguish Energy-saving mode, in this state, not only the shape of the above-mentioned membrane keyboard of each Operation switch SW1~SW11 or text importing etc. can not See, and in the case of this embodiment, the covering upper surface part in addition to 51 part of steam component of above-mentioned lid 2 The entirety of whole inscription plate main body 20 also almost becomes completely black sootiness face.Therefore, in this state, with 60A pairs of liquid crystal display panel The part answered needless to say, even each Operation switch SW1~SW11 and the operating surface configured with each Operation switch SW1~SW11 60 part of plate itself is actually also indefinite in where.

Therefore, if due to reason of the atmosphere temperature around above-mentioned human body sensor MS than fever etc. people When the detection input of body induction sensor MS cannot trust, even if to be constituted to by the touch sensor of above-mentioned electrostatic capacitance method Each Operation switch SW1~SW11 touch operation (increase for the capacitor that swims) on the basis of, it is desirable to using above-mentioned releasing energy conservation Structure as mode, for a user, reliably the part touch operation switch SW1~SW11 is also no longer easy.Therefore, lead to The method that the above-mentioned touch to soft-touch control is detected is crossed, energy-saving mode cannot be reliably and quickly released.

In addition, needing to carry out in the case where detecting the movement that user will operate and the touch to soft-touch control The operation of two-stage: the touch operation of first time is the releasing of energy-saving mode, is control input from secondary touch operation Operation, moreover, for avoid vibration continuous operation caused by erroneous input, it is necessary in above-mentioned first time and secondary operation Be spaced apart specified value more than time difference judged.This leads to bad response, and input processing also becomes complicated, and controls journey Sequence also complicates.

Therefore, it is necessary to a kind of releasing devices of unlike those described above, more reliable and maneuverable energy-saving mode.The implementation Mode, for the purpose of solving this technical task, on the basis of human body sensor MS as described below, setting detection is used Family will operate the operation detection sensor KS of Operation switch, defeated in the correctly detection that cannot expect human body sensor MS In the situation as described above entered, when detecting that user will operate Operation switch by operation detection sensor KS, make The non-power status that the sensor circuit of the Operation switch never can be carried out the setting of control input, which reverts to, is able to carry out control The energized state of the setting of input.

Therefore, above-mentioned energy-saving mode is being released using above-mentioned human body sensor MS or operation detection sensor KS, and When above-mentioned light emitting diode L1~L19, L20~L24 are lighted, aforesaid operations panel part 60, which becomes, to be lighted as Figure 24, shows State, clearly displays shape and the text etc. of the membrane keyboard of each Operation switch SW1~SW11 from inside, user be very easy into Row operation.Meanwhile liquid crystal display panel 60A also lights display with backlight, shows necessary input information.

In addition, as detailed in the following, being equipped with detection in the case where the embodiment on above-mentioned micro computer substrate 60B and existing Such as thermoelectric type sensor having users in corresponding region as defined in position corresponding with operation panel 60 etc. is constituted Human body sensor MS, such as except in cooking, timer preset cook in, timer preset determine in, heat preservation it is medium Control input setting after standby mode except operation standby mode under, in user not as defined in operation corresponding position etc. (to sum up, the presence of user is not detected in human body sensor MS more than the stipulated time in the case where in corresponding region In the case where), by the membrane keyboard of aforesaid operations switch SW1~SW11, touch sensor, light emitting diode L1~L19, liquid crystal surface The controls such as light emitting diode L20~L24 of plate 60A are the energy-saving mode that power supply is closed, in the display function and photograph of liquid crystal display panel On the basis of bright function, also the operating function of aforesaid operations switch SW1~SW11 and illumination functions are set to close, thus Consumption electric power is reduced as much as possible.

As a result, under the energy-saving mode, above-mentioned 80 part of waterproof cover for example via the sootiness resin material of black and Setting, mutually cooperates with it, such as such as Figure 23, and the upper surface of the lid 2 of the electric cooker main body becomes opaque state, becomes and remove With other than the light of the human body sensor MS as described below corresponding part concave 80a opening 20c almost Sightless state.

Certainly, in this case, carry out it is necessary do not need " in cooking ", " in timer preset ", " timer preset determine In ", the display under the standby mode of the normal mode of the operation setting of the control input of " in heat preservation " etc..

The structure of human body sensor of the < in relation to cap portion and its setting construction >

In the case where the embodiment, such as shown in Figure 23~Figure 26, it is equipped in the part by a front left side of lid 2 upper The human body sensor MS stated.It is sensed shown in the people's body induction sensor MS and Fig. 9~Figure 12 of above-mentioned embodiment 1 Device is identical, as by operation setting or the confirmation etc. of operation setting state etc., detecting user close to the electric cooker main body just Surface side operates corresponding position, and its upper part of the body (such as shoulder or face, hand etc.) comes the people in operation panel portion 60 and detects sensing Device works.

The construction > of < the operation detection sensor in relation to energy-saving mode releasing and the operation detection sensor

On the other hand, in present embodiment, on the basis of above-mentioned human body sensor MS, such as such as Figure 23~figure Shown in 27, near the human body sensor MS of above-mentioned lid 2 part, more particularly, in the inscription plate main body 20 of lid 2 Human body sensor MS infrared ray light the first light with being equipped with energy-saving mode releasing around opening 20c Operate detection sensor KS (referring to Figure 26).

The operation detection sensor MS is by substantially identical as the soft-touch control for constituting above-mentioned each Operation switch SW1~SW11 Electrostatic attraction electrode and electrostatic capacitance detection sensor constitute.Electrostatic attraction electrode is formed as surrounding the of above-mentioned human body sensor MS The construction of annular of one light around opening 20c, electrode area (electrode width) are formed as at least corresponding user's Sufficiently wide the area more than projected area of finger tip can correspondingly produce between human body with the finger tip of user or palm The capacitor that swims of raw sufficient amount.

On the other hand, the electrostatic capacitance detectability (detection sensitivity) of electrostatic capacitance detection sensor, it is above-mentioned with constituting The detection sensitivity of the touch sensor of the soft-touch control of each Operation switch SW1~SW11 is compared, and is set to quite high.Thus Be configured to, the case where not only finger tip of user directly contacts the electrostatic attraction electrode of ring-shaped, and can be effectively detected from Open the increase for leaving the capacitor that swims in the case that position is covered with palm of predetermined distance.

Detected using above-mentioned electrostatic capacitance detection sensor a reference value of the capacitor that swims generated between human body with On increased situation under, i.e., user operates operation detection sensor KS (covering with Fingertip touch or with palm) with hand and incites somebody to action In the case where releasing energy-saving mode, above-mentioned electrostatic capacitance detection sensor generates energy-saving mode ring off signal, and the signal is defeated Enter aftermentioned first microcomputer control unit 100A (referring to Figure 29), the first microcomputer control unit 100A is released Operation switch The controls such as the touch sensor circuit of SW1~SW11 are the energy saving mould that the second microcomputer control unit 100B of energy-saving mode is carried out Formula can carry out the setting of control input by the touch operation of various Operation switch SW1~SW11.

Moreover, in this case, operating the annular of detection sensor KS as shown in Figure 23, Figure 24, Figure 25, Figure 26, Figure 27 Electrostatic attraction electrode, it is corresponding with above-mentioned human body sensor MS, to surround the light opening of above-mentioned human body sensor MS Mode around portion 20c is arranged.Therefore, such as above-mentioned, the second micro computer control list of the touch operation detection of soft-touch control First 100B and LED driving circuit 123 are set to the energy-saving mode as non-power status, in above-mentioned inscription plate main body In the case that 20 operation panel 60 and the part liquid crystal display panel 60A are the sootiness state of Figure 23 of OFF state, should part and Speech, due to waterproof cover 80 it is concave for concave spherical surface construct and form concavees lens 80a, so be very easy to identification, and touch operation or Masking palm is also easy.

Moreover, thus, it is possible to Operation switch SW1 will currently be operated by detecting the first microcomputer control unit 100A easily Therefore the state of~SW11 needs to release current energy-saving mode (in the embodiment, for detecting micro computer in this way " operation detection sensor " such performance in the meaning of the sensor for the state that ground is operated, is used, can also directly be said At " the energy-saving mode releasing sensor " as its premise).

As a result, if carrying out the row of above-mentioned touch operation or masking palm for operation detection sensor KS For the capacitor increase of swimming then generated between the electrostatic attraction electrode and human body of operation detection sensor KS, is regulation in the capacitor A reference value more than at the time of, from above-mentioned electrostatic capacitance detection sensor export indicate user to operate Operation switch SW1~ The state of SW11, operation detection signal (energy-saving mode ring off signal) for therefore needing to release energy-saving mode, and the signal is defeated Enter above-mentioned first microcomputer control unit 100A.

If there is the input of the detection signal, then above-mentioned first microcomputer control unit 100A is released due to no above-mentioned people The people of body induction sensor MS detects input and the energy-saving mode of setting, and no matter whether there is or not the detections of above-mentioned human body sensor MS Input it is unrelated, at least with lid 2 close for condition (the detection signal without aftermentioned inclination sensor IS), make power supply to above-mentioned The touch sensor circuit or light emitting diode L1~L19 of Operation switch SW1~SW11, the driving circuit 123 of L20~L24 Supply restores, the energy-saving mode before releasing, and makes the touch sensor circuit or luminous two of above-mentioned Operation switch SW1~SW11 The work of driving circuit 123 of pole pipe L1~L19, L20~L24, are able to carry out necessary input control, drive control.

2-1) variation 1

In addition, in this case, also using following structure: for example as shown in figure 27, for being located at apart from above-mentioned The Operation switch of the nearest position of the setting unit of operation detection sensor KS, such as the touch electrode of heat preservation selection switch SW8 are (quiet Electrode) TS8, be formed as (in Figure 27, opening with other Operation switch SW1~SW7, SW9~SW11 to complete level set SW11 is closed to be representative and show) touch electrode (TS11) compared to the comparatively wide area of width electrode so that and human body Between the variable quantity of the variation of the capacitor that swims that generates it is larger, meanwhile, for the text importing lighted by light emitting diode The area ratio of the portion part LED8, but also it is comparably sizable value with other area ratios.

By being formed as above structure, (standby/extinguishing is operated in the sootiness state of above-mentioned energy-saving mode shown in FIG. 1 State) under, it, be easy to a certain degree depending on recognizing, is mark with it, it is easier to know compared with other switches which, which selects switch SW8, Road operation detection sensor KS there are position (do not only rely on recess be concave spherical surface shape concavees lens 80a).

Also, in the case of that construction, when constituting as follows, that is, sensed being detected by aforesaid operations On the basis of device KS carries out the releasing of non-power status, and with the releasing for carrying out non-power status by the touch to soft-touch control Function when, can effectively utilize and increase the soft-touch control of the electrode area.

2-2) variation 2

For constituting the electrostatic attraction electrode portion of the soft-touch control of aforesaid operations switch SW1~SW11 (referring to the symbol of Figure 28 The part TS11) be described in more detail if, then as shown in figure 28, consist of: be set to inscription 20 part of plate main body, on it Printing material 79 is arranged via the sootiness material 78 of black in portion, and further, the upper surface of the printing material 79 is by as inscription plate cover Waterproof cover 80 covered.

Therefore, under above-mentioned energy-saving mode, the operation comprising the electrostatic attraction electrode portion TS11, character display unit LED11 is opened The entirety for closing SW11 effectively hardly may be used by above-mentioned each component (especially sootiness material 78) with the masking of sootiness state See, realizes the salubrious brand-new electric cooker design of the upper surface of lid 2 shown in FIG. 1.

Certainly, above-mentioned to can be used as effective structure and be carried out, according to the demand of product, there is also following feelings sometimes Shape: it is desirable that the only periphery side section of the light shallow visible membrane keyboard (operation portion) other than above-mentioned character display unit LED11 is quiet The part electrode TS11.

Therefore, it as countermeasure at this time, such as shown in the cross-section of Figure 28, constitutes as follows: by above-mentioned sootiness material The thickness of the part a corresponding with electrostatic attraction electrode TS11 of material 78 is formed in a manner of defined thickness thinner than other parts, from And the part of the electrostatic attraction electrode TS11 of membrane keyboard periphery is with cyclic annular light shallow appearance.At this point, can both make printing material 79, waterproof Cover 80 follows the variation of the thickness of part a and is recessed as groove planar, can also there are with 78 thinning part split-phase of sootiness material Corresponding gap is formed as planar in shape.

In other each operation keys, identical structure can also be used.

In the case of this kind of construction, when constituting as follows, that is, passing through aforesaid operations detection sensor On the basis of KS carries out the releasing of non-power status, and with the releasing for carrying out non-power status by the touch to soft-touch control When function, it should which the position of the touch key section of operation becomes clear, and therefore, release operation is more reliable.

The structure > of control circuit of the < in relation to electric cooker main body

Next, what Figure 29 expression was constituted centered on the microcomputer control unit of the electric cooker of above embodiment 2 It cooks and the structure of heat-preservation control circuit.

The control circuit of the Figure 29 is substantially the same with the above-mentioned control circuit of Figure 20 of embodiment 1, such as following, Feature is the above-mentioned operation detection sensor KS that Operation switch SW1~Sw11 will be operated equipped with detection user.Therefore, with Under explanation in, only illustrate this feature part.

That is, in the case where the structure of above embodiment 1, in the state of moving to energy-saving mode, on user comes In the case that states is able to carry out in the defined region detected, normal detection function is able to maintain that in human body sensor MS Under conditions of energy, is closed with lid 2 as condition, restore touch sensor circuit or hair of the power supply to Operation switch SW1~SW11 The supply of the driving circuit 123 of optical diode L1~L19, L20~L24, the energy-saving mode before releasing open above-mentioned operation The driving circuit 123 of the touch sensor circuit or light emitting diode L1~L19, L20~L24 of closing SW1~SW11 acts, and carries out Necessary input control, drive control.

On the other hand, symbol KS is for releasing due to not passing from above-mentioned human body sensing more than the defined time The detection of sensor MS inputs and the operation detection sensor of the energy-saving mode releasing of the above-mentioned energy-saving mode of setting, operation inspection It is for example above-mentioned by having the electrostatic transducer for the electrostatic attraction electrode for forming ring-shaped to constitute to survey sensor KS.Moreover, the electrostatic attraction electrode with Above-mentioned human body sensor MS is corresponding, to surround the light of above-mentioned human body sensor MS with around the 20c of opening portion Mode and be arranged.

Therefore, as above-mentioned, the second microcomputer control unit 100B and light emitting diode of touch operation detection drive electricity Road 123 is set to non-power status i.e. energy-saving mode, operation panel 60 and the portion liquid crystal display panel 60A in above-mentioned inscription plate main body 20 It should be concave spherical surface structure since waterproof cover 80 is concave for part in the case where the sootiness state for being divided into Figure 23 of OFF state It makes and forms concavees lens 80a, so being very easy to identification, and touch operation or masking palm are also easy.

Moreover, thus, it is possible to easily make operate detection sensor KS detect will currently operate Operation switch SW1~ The movement of SW11.If carrying out the behavior of above-mentioned touch operation or masking palm for operation detection sensor KS, grasp The capacitor increase of swimming for making to generate between the electrostatic attraction electrode and human body of detection sensor KS, becomes defined a reference value in the capacitor Above timing, output indicate that user will operate the operation detection signal of the state of Operation switch SW1~SW11, and by the signal Input above-mentioned first micro computer control component 100A.

If there is the input of the detection signal, then above-mentioned first microcomputer control unit 100A is released due to no above-mentioned people The people of body induction sensor MS detects input and the energy-saving mode of setting, and no matter whether there is or not the detections of above-mentioned human body sensor MS Input is at least closed with lid 2 as condition, make power supply to the touch sensor circuit of above-mentioned Operation switch SW1~SW11 or The supply of the driving circuit 123 of light emitting diode L1~L19, L20~L24 restores, and the energy-saving mode before releasing makes above-mentioned Touch sensor circuit or light emitting diode L1~L19,123 work of driving circuit of L20~L24 of Operation switch SW1~SW11 Make, is able to carry out necessary input control, drive control.

As above, on electric cooker be arranged human body sensor MS, so as to detect operation Operation switch SW1~ The user's of the part SW11 whether there is, and in the presence of user, can automatically make the biography of Operation switch SW1~SW11 Sensor circuit or LED driving circuit become driving condition, are able to carry out the operation setting of necessary control input；Separately On the one hand, the institute for being not present, being set without carrying out any operation premised on to cook or keep the temperature in the stipulated time above user In the case where meaning " operation standby mode ", by sensor circuit from power supply to Operation switch SW1~SW11 or light emitting diode The supply of driving circuit is set as closing, and not can be carried out the setting of control input, can move to the waste that can save consumption electric power Energy-saving mode.

On the other hand, under the energy-saving mode (non-power status), when user will newly start operation, above-mentioned human body sensing Sensor MS detects the presence of user again, therefore, can be made by the detection of the people's body induction sensor MS input above-mentioned The sensor circuit or LED driving circuit of Operation switch switch SW1~SW11 becomes driving condition, is able to carry out control Make the setting of input.

But this case where being user's detection function proper function of above-mentioned human body sensor MS eventually.As now Have described in example, above-mentioned human body sensor MS, the atmosphere temperature around the sensor portion is temperature identical with the body temperature of people Degree or more situation or in the case where there is the influence of " meal thin rice gruel ", may not being capable of proper function.Therefore, in such situation Under, it cannot restore from energy-saving mode as described above, it may occur however that although user wants to carry out the setting of necessary control input, And the case where setting of control input can not be carried out.

But, as above-mentioned, when being different from human body sensor MS, Operation switch SW1~SW11 will be operated with user Premised on, setting detection is expressed as the touch operation of the user of the state or covers the electrostatic capacitance detection mode of palm behavior Operate detection sensor KS when, as above-mentioned reason and human body sensor MS cannot normally be detected existing for user In the case of, " touch operation or masking palm behavior relative to operation detection sensor KS " of user, which is judged as, indicates user " the releasing behavior of energy-saving mode " that Operation switch SW1~SW11 will be operated, can make aforesaid operations switches SW1~ The sensor circuit or LED driving circuit of SW11 never can be carried out the non-power status of the setting of above-mentioned control input Revert to the energized state for being able to carry out the setting of above-mentioned control input.

That is, if user's operation (touching or cover palm) releases the operation that sensor works as above-mentioned energy-saving mode Detection sensor KS, then above-mentioned electrostatic capacitance detection sensor, is detected floating between the operation bring human body and electrostatic attraction electrode The increase of a reference value of capacitor or more is swum, generates energy-saving mode ring off signal, and signal input above-mentioned first is micro computer controlled Unit 100A processed, therefore, above-mentioned first microcomputer control unit 100A can release aftermentioned second microcomputer control unit The energy-saving mode of 100B is able to carry out the setting for controlling input that the touch operation of various Operation switch SW1~SW11 carries out.

In this way, the atmosphere temperature around the sensor portion of human body sensor MS is temperature identical with the body temperature of people In the case that above situation or human body sensor MS is unable to proper function because of the influence of " meal thin rice gruel ", can also it lead to It crosses the operation to operation detection sensor KS and the movement of operation portion will be operated by reliably detecting user, and is judged It can make aforesaid operations by making non-power status revert to energized state in detection timing for energy-saving mode release operation Each Operation switch SW1~SW11 in portion promptly moves to the state for being able to carry out operation input.

Therefore, the atmosphere temperature around the sensor portion of human body sensor MS is temperature identical with the body temperature of people More than, the case where detection function of human body sensor MS cannot suitably work or the human body sense due to influence of " meal thin rice gruel " In the case that the detection function of inductive sensing device MS cannot suitably work, it also can reliably input respectively and set necessary cook Information.

Other structures are identical with the above-mentioned structure of control circuit of Figure 20 of embodiment 1, similarly play and make With.
