Razporeditev za čiščenje pečice izum se nanaša na razporeditev za čiščenje pečice, ki obsega pečnjak, pod pečnjakom nameščeno grelo in po potrebi nad pečnjakom nameščeno grelo.The invention relates to an oven cleaning arrangement comprising an oven, a heater under the oven and a heater installed above the oven.
Znane so že pečice, pri katerih se tako pod pečnjakom nameščeno grelo, kakor tudi nad pečnjakom nameščeno grelo razen za pečenje oz. ostalo pripravljanje hrane v pečnjaku uporabljata tudi za takozvano katalitsko samodejno čiščenje pečnjaka. Pri tem se dovede notranji prostor pečnjaka na visoko temperaturo (>550°C), da bi se z notranjih sten pečnjaka odstranilo nečista mesta.There are already known ovens which have both a heater under the oven and a heater above the oven, except for baking or cooking. other cooking in the oven is also used for the so-called catalytic automatic cleaning of the oven. The oven interior is brought to a high temperature (> 550 ° C) to remove any dirty spots from the inside walls of the oven.
To katalitsko samodejno čiščenje je povezano z vrsto pomanjkljivosti. Najprej zahteva katalitsko samodejno čiščenje, kot že omenjeno, relativno visoko temperaturo. To temperaturo je treba pri tem izbrati tako, da se po eni strani lahko doseže zaželen učinek čiščenja, da pa se po drugi strani preprečijo poškodbe oz. postopno uničenje notranjega prostora pečice.This catalytic self-cleaning is associated with a number of disadvantages. First, it requires catalytic self-cleaning, as mentioned above, relatively high temperature. This temperature must be selected in such a way that, on the one hand, the desired cleaning effect can be achieved, but on the other hand, damage or damage can be avoided. the gradual destruction of the interior of the oven.
Katalitsko samodejno čiščenje zahteva velik vložek energije in je povezano tudi z nadaljnjo pomanjkljivostjo, da se pečica v teku relativno dolgega časa čiščenja ne more drugje uporabiti. Ta čas je sestavljen iz časa, v katerem nastaja temperatura delovanja, iz časa dejanskega čiščenja in končno iz časa, ki je potreben, da se pečica ohladi na temperaturo, ki dopušča nenevarno ravnanje s pečico.Catalytic automatic cleaning requires a great deal of energy input and is also associated with the further disadvantage that the oven cannot be used elsewhere for a relatively long cleaning time. This time consists of the time at which the operating temperature is generated, the time of actual cleaning, and finally the time required for the oven to cool to a temperature that permits the oven to be operated safely.
Izhajajoč iz tega stanja tehnike je izum zasnovan na nalogi, da poda razporeditev uvodoma podane vrste, ki poenostavlja samodejno čiščenje pečice.Based on this state of the art, the invention is based on the task of providing an arrangement of the type specified above, which facilitates the automatic cleaning of the oven.
Ta naloga je po izumu rešena z značilnostmi patentnega zahtevka 1. Razporeditev po izumu se odlikuje s tem, da je potrebna samo sorazmeroma nizka temperatura delovanja s približno 50 do 70°C. Pečica in posebno pečnjak s to temperaturo, ki leži daleč pod maksimalno temperaturo delovanja npr. za določene poteke cvretja in pečenja, nista prizadeta. Ustrezno sorazmeroma nizki temperaturi za čiščenje je potrebno za čiščenje samo malo časa, tako da se lahko pečica uporablja za namene, za katere je določena, ustrezno dolgo.This task is solved by the features of claim 1 according to the invention. The arrangement according to the invention is characterized in that only a relatively low operating temperature of about 50 to 70 ° C is required. The oven and especially the oven with this temperature, which lies far below the maximum operating temperature e.g. for certain flowering and baking processes, they are not affected. Properly relatively low cleaning temperatures require only a short time to clean so that the oven can be used for the intended purpose for a sufficiently long time.
Nadaljnjo posebno prednost razporeditve po izumu predstavlja majhna poraba energije, ki je za čiščenje potrebna.Another particular advantage of the arrangement according to the invention is the low energy consumption required for cleaning.
Izum bo sedaj opisan na osnovi risb.The invention will now be described on the basis of the drawings.

Slika 2 stikalnotehnično opremo razporeditve po izumu.Figure 2 Switchgear arrangement according to the invention.
V sliki 1 prikazan pečnjak M se nahaja v električni pečici. Razporeditev po izumu pa se lahko uporabi splošno v povezavi s pečicami. Pečnjak M je oblikovan v obliki kvadra. V področju njegovih tal se nahaja poglobitev, posebno kad W, ki je namenjena sprejemu čistilnega sredstva R kot npr. izplakovalnega luga ah čistila za emajl. Pečnjak M in kad W sta lahko oblikovana enodelno, alternativno je predvidena ločena kad W.Figure 1 shows the M oven located in the electric oven. The arrangement according to the invention may, however, be used generally in connection with ovens. The M oven is square shaped. There is a recess in the area of its floors, especially the tub W, which is intended to receive a detergent R such as e.g. flushing lye ah enamel cleaners. Oven M and bathtub W may be formed in one piece, alternatively a separate bathtub W may be provided.
Pod pečnjakom M je na znan način predvideno v sliki 1 električno grelo, ki povzroča ogrevanje od spodaj za poteke cvretja oz. pečenja, izvajane v pečici. To grelo je oblikovano zlasti z dvema grelnima palicama Rl in R2, ki potekata približno vzporedno vzdolž stranskih robnikov dna pečnjaka in sta krmiljeni s stikalno pripravo, prikazano v sliki 2.Under the M oven, in the known manner, an electric heater is provided in Fig. 1, which causes the bottom to be heated for the flow of the boiling water. baking done in the oven. This heater is designed in particular by two heating rods Rl and R2 which run approximately parallel along the side edges of the bottom of the oven and are controlled by the switchgear shown in Figure 2.
Pečica ima lahko nadaljnje, v sliki 1 neprikazano grelo (RO v sliki 2) za povzročanje ogrevanja od zgoraj, pri čemer se lahko za poteke cvretja oz. pečenja s stikalno pripravo S (slika 2) istočasno aktivirata pod pečnjakom M nameščeni greli Rl, R2 in nad pečnjakom M nameščeno grelo, da bi se dovedlo snovi, ki se cvre oz. peče, istočasno ogrevanje od spodaj in od zgoraj. Pri tem sta lahko obe greli (RO; Rl, R2 v sliki 2) predvideni za različno moč. Po potrebi se lahko ogrevanji od spodaj in od zgoraj za potrebe cvretja in pečenja naravnavata individualno v vnaprej podanem območju moči.The oven may have a further unheated heater (FIG. 2 in Figure 1) to cause heating from above, and may be used for boiling or baking processes. firing with switchgear S (Fig. 2) simultaneously activates the heaters R1, R2 under the oven M and the heated heater above the oven M, in order to supply the substances which are boiling or boiling. furnaces, simultaneous heating from below and from above. In doing so, the two heaters (RO; R1, R2 in Figure 2) can be designed for different power. If necessary, the heating from below and from above for the sake of frying and baking can be adjusted individually in the predefined power range.
Elektrotehnično krmiljenje pod pečnjakom M nameščenega grela bo pojasnjeno na osnovi slike 2.The electrical control under the oven M of the installed heater will be explained on the basis of Figure 2.
V kad W dovedeno oz. na dno pečnjaka nanešeno čistilno sredstvo R se z grelom Rl, R2, nameščenim pod pečnjakom M, segreje in na koncu izpari. Posebno povzroča pod pečnjakom nameščeno grelo Rl, R2 med dvema sledečima si časovnima razdobjema različni temperaturi, ki najprej čistilno sredstvo R segrejeta in končno uparita.In the tub W brought or. The cleaning agent R applied to the bottom of the oven was heated with heat R1, R2 under the oven M and finally evaporated. In particular, the heater R1, R2 installed under the oven causes different temperatures between the two subsequent periods, which first heat the detergent R and finally evaporate.
Kot čistilno sredstvo R je uporabljen na primer izplakovalni lug ali čistilo za emajl. Prvo časovno razdobje se nahaja na primer v področju 3 do 4 minut, medtem ko se nahaja drugo časovno razdobje v področju 5 do 8 minut. V prvem časovnem razdobju se s segrevanjem čistila R raztopijo nečistoče v področju dna pečnjaka oz. kadi W. V drugem časovnem razdobju prispe vparjeno čistilo R neposredno na stene pečnjaka in gornje prekrivalo pečnjaka in učinkuje neposredno na tam nahajajoče se nečistoče.For example, a flushing lye or an enamel cleaner is used as the R cleaner. For example, the first time period is in the range of 3 to 4 minutes, while the second time period is in the range of 5 to 8 minutes. During the first period, the impurities in the area of the bottom of the oven or the oven are dissolved by heating the cleaner R. bathtub W. During the second period, the evaporated R cleaner arrives directly on the oven walls and the upper oven cover and has an effect on the impurities present there.
V sliki 2 je prikazana stikalna priprava S, s katero se lahko ločeno aktivira pod pečnjakom M nameščeno grelo Rl, R2 na tak način, da povzroči to temperaturo, ki upari v pečnjak M dovedeno čistilno sredstvo R,Figure 2 shows a switching device S which can be activated separately under the oven M by the installed heater R1, R2 in such a way that it causes this temperature to evaporate into the oven M the cleaning agent R supplied,
Stikalna priprava S sestoji iz upravljalnega elementa B, ki je lahko na primer izveden s stikalnim zasučnim gumbom, s tipko tipkovnice ali pa z drugim upravljalnim elementom.Switching device S consists of a control element B, which may, for example, be made by a rotary knob, a keyboard key or another control element.
Dodatno lahko vsebuje stikalna priprava S vezje Z, ki aktivira, sproženo z ročnim upravljanjem upravljalnega elementa B, grelo Rl, R2 na tak način, da povzroča grelo Rl, R2 v drugo drugemu sledečih razdobjih različne temperature, pri čemer je temperatura v drugem razdobju (faza upaijanja) višja od temperature v predhodnem razdobju (faza ogrevanja).In addition, the switching device S may comprise a circuit Z which activates, triggered by manually operating the control element B, the heater R1, R2 in such a way that it causes the heater R1, R2 in different periods of time in the following periods, the temperature being in the second period ( absorption phase) higher than the temperature in the previous period (heating phase).
Temperatura uparjanja znaša na primer 50 do 70° C.The evaporation temperature is, for example, 50 to 70 ° C.
Uparjeno čistilo povzroči, da odstopijo nečistoče na stranskih stenah in na stropu pečnjaka M. Eventualno še preostale nečistoče se relativno lahko odstranijo ročno.The evaporated detergent causes the impurities on the side walls and the ceiling of the oven M. to be removed. If necessary, any remaining impurities can be removed relatively manually.
Pod pečnjakom nameščeno električno grelo je prikazano z ohmskima uporoma RI in R2.An electric heater installed under the oven is indicated by the ohmic resistors RI and R2.
Stikalna komponenta Z je lahko nadalje oblikovana na tak način, da se za regularne potrebe cvretja in pečenja pečice, vključene z ustreznim delovanjem na upravljalni element B, da se prek stikala SW3 skupaj aktivirata pod pečnjakom nameščeno grelo RI, R2 za ogrevanje od spodaj z nad pečnjakom nameščenim grelom RO za ogrevanje od zgoraj.The switching component Z may be further designed in such a way that, for regular cooking and baking purposes, the ovens, incorporated by proper operation on the control element B, can activate the heating element RI, R2 for heating from below with above via the switch SW3. Oven RO heaters for heating from above.
Stikalna komponenta Z krmili dve stikali SW1 in SW2 in s tem prirejenost med seboj oz. k napetosti U.Switching component Z controls two switches SW1 and SW2 and thus their alignment with each other. to the voltage U..
V prvem stikalnem položaju (SW1: 1, SW2: 1) sta grelna elementa vezana vzporedno; v drugem stikalnem položaju (SW1: 2, SW2: 2) sta grelna elementa vezana zaporedno. S prvim stikalnim položajem se v odvisnosti od absolutnih vrednosti ohmskih uporov RI in R2 povzroča višja ogrevna moč kot v drugem stikalnem položaju.In the first switch position (SW1: 1, SW2: 1) the heating elements are connected in parallel; in the second switch position (SW1: 2, SW2: 2) the heating elements are connected in series. With the first switch position, depending on the absolute values of the ohmic resistors RI and R2, a higher heating output is produced than in the second switch position.
Prek tega se lahko v tretjem stikalnem položaju (SW1: 1, SW2: 2) aktivira samo grelni element RI in v četrtem stikalnem položaju (SW1: 2, SW2: 1) samo grelni element R2. V odvisnosti od izvedbe RI in R2 se lahko pri vnaprej podani obratovalni napetosti U tvorita nadaljnji (prva in druga) temperaturi za fazo ogrevanja in upaijanja.Only the heating element RI can be activated in the third switch position (SW1: 1, SW2: 2) and only the heating element R2 in the fourth switch position (SW1: 2, SW2: 1). Depending on the design of RI and R2, further (first and second) temperatures may be formed at the pre-set operating voltage U for the heating and evaporation phase.
Neodvisno od teh preklopnih možnosti (zaporedna/vzporedna vezava RI in R2 ter po izbiri priklop RI ali R2) lahko tvori stikalna priprava (S) s krmiljenjem grela RI, R2 v taktu prvo in/ali drugo temperaturo.Independently of these switching options (sequential / parallel coupling of RI and R2 and optionally connection of RI or R2), a switching device (S) may be formed by controlling the RI, R2 heater at the first and / or second temperature.
Navedeni poteki krmiljenja (prvi do četrti stikalni položaj; delovanje v taktu) se krmilijo časovno s stikalno komponento Z na tak način, da je faza ogrevanja (prvo časovno razdobje) omejena na 3 do 4 minute, medtem ko je predvsem neposredno sledeča faza upaijanja (drugo časovno razdobje) omejena na nadaljnjih 5 do 8 minut.These control courses (first to fourth switching position; clocking) are controlled temporarily by switching component Z in such a way that the heating phase (first time period) is limited to 3 to 4 minutes, while, in particular, the next absorption phase ( second time period) limited to a further 5 to 8 minutes.
