Roughly can produce four kinds of error situation or faults that cause protector or protection switch the response interruption of current of heating element heater (promptly through) the embodiment that in ensuing description, further introduces of the present invention in service, promptly the sky of the dried running of steam cooking apparatus, steam cooking apparatus boil, the calcification (this causes in the poorer heat transmission between heating element heater and the evaporating dish) of the vessel of steam cooking apparatus and the defective of electric current supply or heating element heater or hot connection between heating element heater and evaporating dish or heat bridge.
Fig. 2 has shown the sketch map of steam cooking apparatus 200 according to an embodiment of the invention.Steam cooking apparatus 200 is parts of stove 120 and makes it possible to be introduced in the dish in the culinary art chamber 205 with vapor action culinary art chamber 205 with culinary art.Water tank 210, pump installation 220, heating element heater 230, the protector that has special function or protection switch 240, evaporating dish 250, controller 260 are shown and are arranged in the temperature inductor 270 of cooking in the chamber 205 or monitoring the temperature of culinary art chamber 205.Even it not in Fig. 2 the diagram shown in; Steam cooking apparatus 200 can have the other protector of connecting with protector or protection switch 240, and it is monitored the temperature of heating element heater 230 equally and when heating element heater 230 becomes too hot, finishes the electric current through heating element heater 230.
According to the diagram among Fig. 2, controller 260 has electronic installation and alarm or indicating device 275 or display, and it for example is connected with control or faulty identification supervising device 260 via system bus or is integrated in the controller 260.Controller 260 is configured to measure the electric current of calandria 230 and visually and/or acoustically indicate the determined failure cause of steam cooking apparatus 200 of flowing through; For example via alarm or indicating equipment 275, it can be from the outside perception well of home appliances 100 for the operator of home appliances.
In addition, controller 260 is connected with protection switch 240 with calandria 230 via first electrical wire 280.Via second electrical wire 285, controller 260 is connected with temperature inductor 270.Heating element heater 230 is arranged in evaporating dish 250 belows and heats by means of the electric current 287 through heating element heater 230.Voltage in the circuit of first lead 280 is about 230V.The heat that in heating element heater 230, is produced is via being passed to waterborne in the evaporating dish 250 at the heat bridge 288 between heating element heater 230 and the evaporating dish 250 (for example under using the situation of heat-conducting glue) through evaporating dish 250, so that produce thus for the essential water vapour of cooking process.
In the circuit that comprises heating element heater 230, be integrated with protector or protection switch 240, when heating element heater 230 heats too tempestuously, the electric current that protector or protection switch 240 interrupt through heating element heater 230.Via the 3rd electrical wire 290, controller 260 is connected with pump 220 or magnetic valve.Via privates 290, controller 260 is issued to pump 220 places with filling signal 292 existing under the situation of predetermined condition.In response to filling signal 292, pump 220 is transported to water in the evaporating dish 250 from water tank 210 via pipeline 295.
Fig. 3 has shown timetable, and it repeats the related of different failure causes and different duration of being obtained according to embodiments of the invention, and wherein, the diagram of Fig. 3 only is used for effectively related illustrate and so not being pro rata.At first, start electric current 287 and Measuring Time section 300 through controller 260 constantly at 0s through heating element heater 230 by Fig. 2, until the electric current 287 through heating element heater 230 since the response of protection switch 240 be interrupted.First error situation or first failure cause " do running " (next indicating) by U1 the startup stage in can be through calandria 230 until owing to discern or measure the very short heat time heating time of the current interruptions of protector 240.If the measured value of duration 300 is among the very first time window Z1 that comprises less than 20 seconds value, can identify this error reason U1 so.Can consider at this, but for example it in fact also was not heated to the degree of evaporation water in one second very little and time interval Z3 early in zero second after the startup of the electric current 287 through heating element heater 230.Therefore, error reason " is done and is turned round " and in this time interval Z3 early, can't be confirmed clearly.Especially, if the duration 300 of being obtained is among 1 second to 20 seconds the very first time window Z1, so therefore can identify failure cause U1 (" doing running ").
When this triggering is in when comprising from the second time window Z2 that starts 287 20 to 60 seconds the value of electric current through heating element heater 230, error situation or failure cause " vessel calcification " (next indicating with Reference numeral U2) can be discerned through the triggering of protection switch 240 (or in a plurality of protection switch one of them).Although in vessel 250, have water; But owing to be used as the calcium precipitate thing in vessel 250 of insulating barrier; The transmission of heat is so worsened, and makes at the long-pending heat at heating element heater 230 places this heating element heater 230 of heating lentamente, makes protection switch 240 in the second mentioned time interval Z2, trigger.
In order to discern the vessel of calcification ahead of time, also can activate a kind of special test program automatically, wherein, if advise such cleaning or deliming, indication " vessel deliming/cleaning " is displayed on the display of alarm device 275 so.If test program causes this result; Promptly; The deliming of evaporating dish 250 or clean optionally is used for power or electric current that the maximum of heating element heater 230 allows according to described embodiment so and on 60 seconds inspection duration T 3, is supplied to heating element heater 230.This means that be conducted through the time period that heating element heater 230 reaches 60 seconds for the heating element heater 230 maximum electric currents that allow, wherein, one or more protection switches 240 should not trigger.If trigger one or more protection switches 240, can and should carry out the cleaning or the deliming of evaporating dish 250 from the calcification of the increase of evaporating dish 250.In order this information to be shown to the operator of steam cooking apparatus, for example manifest indication " vessel deliming/cleaning " at alarm device 275 places.
Error situation or failure cause " sky boils " (in Fig. 3, marking with Reference numeral U3) during cooking can at any time produce.If at normal operation period (promptly after the electric current through heating element heater 230 287 is connected after 60 seconds time period) the one or more protection switches 240 of triggering; Filling signal 292 is automatically sent to magnetic valve or pump 220 places, fills evaporating dish 250 so that be used to from the water of water tank 210.The memory of the duration that is used for being obtained is resetted once more and successfully fills or import the electric current 287 through heating element heater 230 according to inferring once more after successfully filling evaporating dish 250 from the water of water tank 210 being used to.Remeasure the time period 300 until interruptive current 287 through the triggering of one or more protection switches 240.If in the continuation of gastronomical process, produce again error image (Fehlerbild) (" do running ") (promptly before in the described time window Z1 one or more protection switches trigger), in water tank 210, confirm not exist water.For example corresponding then signal " do not exist water-＞fill water tank " is issued to the client or the user of steam cooking apparatus 200 via the indicating member of the alarm device 275 of steam cooking apparatus.In this error situation, evaporating dish 250 also can visually be identified as dried.
Error situation or failure cause " no current-＞after-sale service " (in Fig. 3, marking with Reference numeral U4) are characterised in that does not have heating, does not promptly have the electric current 287 that passes through heating element heater 230.Here, reason is an electronic installation or to the defective of the electric current supply or the protection switch 240 of calandria 230.In the display of the alarm device 275 of steam cooking apparatus 200, send the signal that is used for indication " fault/after-sale service ".Through the i.e. no current heating element heater 230 of flowing through so, this mistake U4 is identified after can being right after and when surveying, beginning.In this situation, the startup through counter and be next to for example stopping to measure duration 300 of this less than 1 second.
In a kind of possible further design of the mode of being introduced herein; PT1000 inductor 270 can be monitored the culinary art chamber 205 of steam cooking apparatus 200; Wherein, Inquired together through these inductor 270 other additional informations (heating period that for example begins or accomplish), when confirming error reason, can additionally be utilized these information.For example, triggering until 1 second time window Z3 from extension in 0 second, when identification failure cause U3 (" sky boils "), also identifying this reason U3 so if this additional information can be used to one or more protection switches 240.In this situation; Be used to before the water of water tank 210 is filled evaporating dish 250; Steam cooking apparatus 200 correctly works; Make culinary art chamber 205 for heat, the reason that sky boils than the defective of the electronic unit of heating element heater 230, protection switch 240 or lead 280 or controller 260 obviously more likely.
The mode of introducing according to this place, above therefore mentioned reason or the error situation of the emerged in operation of steam cooking apparatus can through the electric current through calandria simply, additionally integrated monitoring (with the combined ground of time inquiry) quilt is recognized and is identified decides.So for example can notify reason that the user identifies or the error image that is identified via the plaintext in display indication or via audible signal.Can save into this locality with this mode and avoid other sensor, for example be used for the liquid level sensor of the liquid level of water tank 210.
