UREĐAJ ZA PRIPREMUPREPARATION DEVICE
NAPITAKA SA TERMOBLOKOMI BEVERAGES WITH THERMO BLOCKS
KOMORAMA ZA PRIPREMU NAPITAKA CHAMBERS FOR BEVERAGE PREPARATION
Predmetni pronalazak se odnosi na uređaje za pripremu napitaka kuvanjem, kao i na postupak rukovanja takvim uređajem za pripremu napitka. The subject invention relates to devices for preparing beverages by cooking, as well as to the procedure for handling such a device for preparing beverages.
U opštem slučaju, predmetni pronalazak se odnosi na uređaje za pripremu napitaka koji sadrže termoblok, tj. uređaj u kojem se zagreva voda u takozvanom „termobtoku" kako bi se proizvela vrela voda i/ili para. Termin „termoblok" u sklopu predmetnog pronalaska ima značenje uređaja za izmenu toptate kod kojeg se tokom pumpanja vode, ona i zagreva (na primer pomoću električnih otpornika). In general, the present invention relates to devices for preparing beverages that contain a thermoblock, i.e. a device in which water is heated in a so-called "thermoflow" in order to produce hot water and/or steam. The term "thermoblock" as part of the present invention has the meaning of a device for changing the tappet in which, during the pumping of water, it is also heated (for example, by means of electric resistors).
Kako bi specifične karakteristike termobloka, u poređenju sa kotlom bile jasnije, kod kotla zagrejana voda ili para cirkuiišu i napuštaju kotao tek nakon što je završen proces zagrevanja ali ne i u toku tog procesa. U opštem slučaju kotlovi imaju i nedostatak da sistem u kojem se oni nalaze poseduje sporiji odziv zbog toga što je termalna inercija dosta veća. In order to make the specific characteristics of the thermoblock, compared to the boiler, clearer, with the boiler, the heated water or steam circulates and leaves the boiler only after the heating process is completed, but not during that process. In general, boilers also have the disadvantage that the system in which they are located has a slower response due to the fact that the thermal inertia is much higher.
Sa druge strane, temnoblokovi tokom rada koriste daleko veće količine električne energije. On the other hand, temnobloks use much larger amounts of electricity during operation.
Uređaj za pripremu napitaka prema predmetnom pronalasku poseduje nekoliko komora za kuvanje, tj za pripremu napitka. Komora za pripremu napitka je većim delom zatvorena komora koja sadrži sastojke od kojih se priprema napitak. Kada se vrela voda (iz termobloka) pod pritiskom uvede u komoru za kuvanje, ona se meša i deluje sa sastojcima za pripremu napitka čime se proizvodi napitak, tj. u opštem slučaju jestiva tečna namirnica. Treba primetiti da predmetni pronalazak obuhvata sve različite načine interakcije između sastojaka za pripremu napitka i vode, kao što su na primer ekstrakcija, rastvaranje, mešanje sa koncentratom i slično. The device for preparing beverages according to the subject invention has several chambers for cooking, ie for preparing beverages. The chamber for the preparation of the beverage is a mostly closed chamber that contains the ingredients from which the beverage is prepared. When hot water (from the thermoblock) is introduced under pressure into the cooking chamber, it mixes and acts with the ingredients for the preparation of the beverage, which produces the beverage, i.e. in general, edible liquid food. It should be noted that the subject invention includes all different ways of interaction between the ingredients for the preparation of the beverage and water, such as for example extraction, dissolution, mixing with concentrate and the like.
Sastojci za pripremu napitaka se mogu nabaviti u različitim oblicima, na primer u praskaš tom, čvrstom, polučvrstom ili tečnom obliku. Ingredients for the preparation of beverages can be obtained in different forms, for example in powder, solid, semi-solid or liquid form.
Dokument EP 577 561 opisuje uređaj za pripremu dva napitka (npr. kafe), ili alternativno jednog napitka i pare ili jednog napitka i vruće vode. Ovaj poznati uređaj može posedovati tri zasebna kotla. Kontrola snage se može vršiti pomoću nekog (mikro)procesorskog sredstva kako bi se snaga selektivno dovodila do dva ili tri kotla. Document EP 577 561 describes a device for preparing two beverages (eg coffee), or alternatively one beverage and steam or one beverage and hot water. This well-known device can have three separate boilers. Power control can be done using some (micro)processor means to selectively supply power to two or three boilers.
Dokument EP-A-502-851 opisuje uređaj prema uvodnom delu nezavisnog Zahteva 1. Document EP-A-502-851 describes a device according to the preamble of independent Claim 1.
Cilj predmetnog pronalaska je da opiše uređaj za pripremu napitaka koji korisniku nudi veću i fleksibilniju ponudu proizvoda koji se pomoću njega mogu istovremeno pripremati i točiti iz više od jedne slavine uređaja. The aim of the present invention is to describe a device for preparing beverages that offers the user a larger and more flexible range of products that can be simultaneously prepared and dispensed from more than one tap of the device.
Ovaj cilj se postiže pomoću sredstava prema navodima nezavisnog Zahteva. Zavisni Zahtevi dalje proširuju centralnu ideju predmetnog pronalaska. This objective is achieved by the means specified in the independent Request. The dependent claims further expand the central idea of the subject invention.
Prema predmetnom pronalasku, uređaj za pripremu napitaka kuvanjem sadrži najmanje jedan rezervoar za vodu. Dalje, uređaj sadrži najmanje dva termobloka koji se mogu selektivno dovesti u protočnu vezu sa najmanje jednim rezervoarom za vodu. Uređaj takođe sadrži najmanje dve komore za pripremu napitka, gde se svaka od njih puni vodom rz jednog od termobtokova. Svaka od komora za pripremu napitka je prilagođena da može da prihvati sastojke za pripremu napitka, a takođe je i povezana sa otvorom za točenje kroz koji se vrši serviranje napitka koji je prethodno pripremljen u komori za pripremu napitka. According to the present invention, the device for preparing beverages by cooking contains at least one water tank. Further, the device comprises at least two thermoblocks that can be selectively brought into flow connection with at least one water reservoir. The device also contains at least two chambers for the preparation of the beverage, where each of them is filled with water from one of the thermoflows. Each of the beverage preparation chambers is adapted to receive ingredients for the preparation of the beverage, and is also connected to a dispensing opening through which the beverage previously prepared in the beverage preparation chamber is served.
Prema predmetnom pronalasku, uređaj za pripremu napitaka, dalje, sadrži zajednički izlazni otvor za točenje vrele vode, na primer otvor za točenje vrele vode koja se selektivno može dovesti iz više od jednog termobloka. According to the present invention, the beverage preparation device further comprises a common hot water outlet, for example a hot water outlet that can be selectively supplied from more than one thermoblock.
Kako je otvor za točenje vrele vode zajednički za više termoblokova, predmetni pronalazak, stoga, predstavlja više od pukog skupa više nezavisnih i paralelnih sistema. As the hot water dispensing opening is common to several thermoblocks, the present invention therefore represents more than a mere collection of several independent and parallel systems.
Uređaj za pripremu napitaka može sadržati upravljačka sredstva, kao i ventile prilagođene da se pomoću njih može vršiti selektivno dovođenje vrele vode iz prvog termobloka do izlaznog otvora za točenje vrele vode u slučaju kada se u jednu od komora za pripremu dovodi vrela voda iz drugog termobloka. The beverage preparation device may contain control means, as well as valves adapted to selectively supply hot water from the first thermoblock to the hot water outlet in the event that hot water from the second thermoblock is supplied to one of the preparation chambers.
Kako bi se ovo postiglo, upravljačka sredstva moraju pratiti trenutni status uređaja za pripremu napitaka kako bi na osnovu toga mogla doneti odluku koji od najmanje dva termobloka neće biti u upotrebi te je, stoga, spreman za zagrevanje vode koja će biti sprovedena do otvora za točenje vrele vode. In order to achieve this, the control means must monitor the current status of the beverage preparation device in order to be able to make a decision based on this which of at least two thermoblocks will not be in use and is therefore ready to heat the water that will be conducted to the hot water outlet.
Uređaj za pripremu napitaka može sadržati upravljačka sredstva i ventile prilagođene za selektivno dovođenje vrele vode simultano iz dva termobloka do zajedničkog otvora za točenje vrele vode u slučaju kada se ni u jednu od komora za pripremu ne dovodi vrela voda iz termoblokova. The beverage preparation device may contain control means and valves adapted to selectively supply hot water simultaneously from two thermoblocks to a common opening for pouring hot water in the event that no hot water from the thermoblocks is supplied to any of the preparation chambers.
Ponovo, za postizanje ovog cilja potrebno je da upravljačka sredstva prate trenutni status uređaja za pripremu napitaka. Kada to praćenje statusa uređaja rezultuje odlukom da niti jedan od termoblokova neće trenutno biti potreban za zagrevanje vode za neku od komora za pripremu napitka, više od jednog termobloka može biti upotrebljeno za zagrevanje vode koja će se sprovesti do zajedničkog otvora za točenje vrele vode čime se praktično povećava (konkretno, u slučaju postojanja dva termobloka i duplira) dotok vrele vode. Again, achieving this goal requires the control means to monitor the current status of the beverage preparation device. When this monitoring of the status of the device results in the decision that none of the thermoblocks will currently be needed to heat water for one of the beverage preparation chambers, more than one thermoblock can be used to heat the water that will be led to the common opening for pouring hot water, which practically increases (specifically, in the case of the existence of two thermoblocks and doubles) the flow of hot water.
Uređaj za pripremu napitaka može opcionalno sadržati najmanje jedan dodatni termoblok radi proizvodnje vodene pare koja će se dovoditi do opcionog otvora za paru, tj. takozvanog „piska" za paru. Otvor za paru može biti zaseban otvor u odnosu na otvor za točenje pripremljenog napitka. The beverage preparation device can optionally contain at least one additional thermoblock for the production of steam that will be fed to the optional steam outlet, i.e. the so-called "beep" for steam. The steam opening can be a separate opening in relation to the opening for dispensing the prepared beverage.
Upravljačka sredstva i ventil uređaja za pripremu napitaka mogu se podesiti, nakon zadavanja komande od strane korisnika, da selektivno aktiviraju dva termobloka od tri postojeća, i to na takav način da se vrela voda selektivno dovodinajmanjedo: The control means and the valve of the device for the preparation of beverages can be set, after giving a command by the user, to selectively activate two thermoblocks out of the three existing ones, in such a way that hot water is selectively supplied to at least:
- dve komore za pripremu napitka, ili - two chambers for preparing the beverage, or
- jedne komore za pripremu napitka i otvora za točenje vrele vode. - one chamber for preparing a beverage and an opening for pouring hot water.
Opciono, jedna komora za pripremu napitka i pisak za paru mogu biti napajani vrelom vodom iz termoblokova. Optionally, one chamber for the preparation of the beverage and the steam nozzle can be supplied with hot water from thermoblocks.
Kao dalja mogućnost, vrela voda se može dovoditi iz termoblokova do otvora za točenje vode i piska za paru. As a further option, hot water can be supplied from the thermoblocks to the water spout and the steam spout.
Konačno, pomoću uređaja se može proizvoditi i veća količina vrele vode. Finally, the device can produce a larger amount of hot water.
Pomoću ovog upravljačkog sredstva se, dakle, povećava fleksibilnost postupka pripreme napitaka, pošto se selektivno istovremeno mogu pripremati najmanje sledeći proizvodi: By means of this control device, therefore, the flexibility of the beverage preparation procedure is increased, since at least the following products can be selectively prepared at the same time:
- dva napitka, - two drinks,
- jedan napitak i vrela voda, i - one drink and hot water, i
- veća količina vrele vode. - a larger amount of hot water.
Opciono, istovremeno se može pripremati i kombinacija vrele vode i pare. Optionally, a combination of hot water and steam can be prepared at the same time.
Prema daljem izvođenju, uređaj može posedovati sredstva za selektivno povezivanje termobloka za proizvodnju pare sa otvorom za pražnjenje, tj. takozvanim „evakuacionim otvorom". Pomoću ovog sredstva za pražnjenje može se vršiti selektivno povezivanje ulazne strane termobloka za proizvodnju pare sa otvorom za pražnjenje. According to a further embodiment, the device may have means for selectively connecting the thermoblock for steam production with the discharge opening, i.e. the so-called "evacuation opening". By means of this discharge means, the inlet side of the thermoblock for steam production can be selectively connected to the discharge opening.
Prema daljem aspektu predmetnog pronalaska, uređaj može posedovati sredstvo za pražnjenje najmanje dva termobloka koji su u vezani sa komorama za pripremu napitka, selektivno povezujući termobtakove sa otvorom za pražnjenje termobloka. According to a further aspect of the present invention, the device can have means for emptying at least two thermoblocks that are connected to the chambers for preparing the beverage, selectively connecting the thermoblocks to the opening for emptying the thermoblock.
Sredstvo za pražnjenje za najmanje dva termobloka, stoga, može vršiti selektivno povezivanje ulazne strane termoblokova sa otvorom za pražnjenje. Discharge means for at least two thermoblocks can therefore selectively connect the inlet side of the thermoblocks to the discharge opening.
Drugim recima, prema predmetnom pronalasku, pražnjenje termoblokova, bilo da je to termoblok za proizvodnju pare ili termoblok povezan protočnom vezom sa komorom za pripremu napitka, prvenstveno se vrši sa ulazne strane termoblokova. In other words, according to the present invention, the discharge of thermoblocks, whether it is a thermoblock for steam production or a thermoblock connected by a flow connection with a chamber for preparing a beverage, is primarily performed from the inlet side of the thermoblocks.
Kako bi se ispraznila najmanje dva termobloka, povezana sa komorama za pripremu napitka protočnom vezom, uređaj može posedovati ventile koji će selektivno vršiti propuštanje vazduha kroz otvor za točenje vrete vode u unutrašnjost termobloka u cilju pražnjenja termoblokova. In order to empty at least two thermoblocks, connected to the beverage preparation chambers by a flow connection, the device can have valves that will selectively allow air to pass through the opening for pouring boiling water into the interior of the thermoblocks in order to empty the thermoblocks.
Drugim recima, prema ovom posebnom postupku pražnjenja termoblokova, vazduh se pušta sa izlazne strane kroz otvor za točenje tako da bilo koja količina zaostale vode može napustiti termoblokove kroz ulaznu stranu kroz koju se uvodi voda. In other words, according to this particular method of emptying the thermoblocks, air is released from the outlet side through the dispensing hole so that any amount of residual water can leave the thermoblocks through the inlet side through which the water is introduced.
Dalji aspekti, prednosti i ciljevi predmetnog pronalaska će postati očigledni osobama sa iskustvom u predmetnoj oblasti nakon čitanja daljeg detaljnog objašnjenja izvođenja koje se poziva na priložene Slike. Further aspects, advantages, and objects of the present invention will become apparent to those skilled in the art upon reading the following detailed description of the embodiment with reference to the accompanying Figures.
Slika 1 šematski prikazuje uređaj za pripremu napitaka, i Figure 1 schematically shows a device for preparing beverages, i
Slika 2 šematski prikazuje sistem za upravljanje takvim uređajem. Figure 2 schematically shows the system for managing such a device.
Na Stici 1 pozicijom 9 je uopštena naznačen uređaj za pripremu napitaka prema predmetnom pronalasku. On Column 1, position 9 indicates a general device for preparing beverages according to the present invention.
Uređaj za pripremu napitaka 9 poseduje najmanje dva rezervoara 1, 2 za vodu koji respektivno poseduju dva sredstva 25, 26 za filtriranje na svojim izlaznim krajevima. Rezervoari 1, 2 za vodu mogu biti uktonjivi kako bi se mogli napuniti vodom na udaljenoj lokaciji i/ili se mogu selektivno dovesti u protočnu vezu sa slavinom 27 za vodu (pri čemu se ne uklanjaju iz uređaja). The beverage preparation device 9 has at least two water tanks 1, 2 which respectively have two filtering means 25, 26 at their outlet ends. The water reservoirs 1, 2 can be collapsible so that they can be filled with water at a remote location and/or can be selectively brought into flow connection with the water tap 27 (without being removed from the device).
Treba primetiti da je postojanje odvojenih rezervoara 1,2 za vodu poželjno radi njihovog jednostavnijeg dopunjavanja vođom od strane korisnika (odnosno radi smanjenja težine pojedinačnog popunjenog rezervoara). Takođe je moguće izvođenje uređaja kod kojeg postoji samo jedan rezervoar za vodu i gde se voda iz tog jednog rezervoara distribuira do svih elemenata uređaja 9 za pripremu napitaka, što će u daljem tekstu biti opisano. It should be noted that the existence of separate tanks 1,2 for water is desirable for their easier refilling with a leader by the user (that is, to reduce the weight of an individual filled tank). It is also possible to design a device where there is only one water tank and where the water from that one tank is distributed to all elements of the device 9 for preparing beverages, which will be described below.
Rezervoari 1, 2 za vodu su povezani jedan sa drugim pomoću cevi ili kanala 28 tako da je dovoljno napuniti samo jedan od rezervoara 1, 2 pošto će se nivoi vode u rezervoarima izjednačiti razmenom tečnosti kroz vod 28. The water reservoirs 1, 2 are connected to each other by a pipe or channel 28 so that it is sufficient to fill only one of the reservoirs 1, 2 since the water levels in the reservoirs will be equalized by the exchange of liquid through the conduit 28.
Izlazni otvori rezervoara 1, 2 su respektivno povezani sa pumpama 29, 30. Opciono mogu biti implementirani i merači protoka 31, 32 radi praćenja protoka vode iz rezervoara 1 i 2 za vodu, respektivno, prema pumpama 29 i 30, čime se takođe prati i protok vode kroz kasnije stepene uređaja za pripremu napitaka (npr. termoblokova, što će biti opisano u daljem tekstu). The outlet openings of the reservoirs 1, 2 are respectively connected to the pumps 29, 30. Optionally, flow meters 31, 32 can be implemented to monitor the flow of water from the water reservoirs 1 and 2, respectively, to the pumps 29 and 30, thereby also monitoring the water flow through the later stages of the beverage preparation device (e.g. thermoblocks, which will be described below).
U svakom slučaju, praćenje količine vode koja se dovodi do termoblokova omogućava da se tačno definisana količina vode propusti kroz termobtokove kako bi se pripremila tačno određena količina vrele vode, napitka i/ili pare. In any case, monitoring the amount of water supplied to the thermoblocks allows a precisely defined amount of water to pass through the thermoblocks in order to prepare a precisely defined amount of hot water, beverage and/or steam.
Pumpa 29 koja je u protočnoj vezi sa prvim rezervoarom 1 za vodu, dovodi vodu pod pritiskom do ulaznog otvora 23 prvog termobloka 4, dok pumpa 30 koja je u protočnoj vezi sa drugim rezervoarom 2 za vodu, dovodi vodu pod pritiskom do ulaznog otvora 24 drugog termobloka 3. Pump 29, which is in flow connection with the first water tank 1, supplies water under pressure to the inlet opening 23 of the first thermoblock 4, while pump 30, which is in flow connection with the second water tank 2, supplies water under pressure to the inlet opening 24 of the second thermoblock 3.
Kao što je već opisano u uvodnom deki, primenjeni termoblokovi su prilagođeni zagrevanju vode pomoću električnih otpornika tokom njenog proticanja kroz cevovod u unutrašnjosti termobloka. As already described in the introduction, the applied thermoblocks are adapted to heat water using electric resistors during its flow through the pipeline inside the thermoblock.
Izlazni otvor termobloka 4 se može dovesti u protočnu vezu sa prvom komorom 6 za pripremu napitka koja poseduje otvor 8 za točenje pripremljenog napitka. Termoblok 3 se može dovesti u protočnu vezu sa drugom komorom 5 za pripremu napitka koja poseduje otvor 7 za točenje pripremljenog napitka. The outlet opening of the thermoblock 4 can be brought into flow connection with the first chamber 6 for preparing the beverage, which has an opening 8 for dispensing the prepared beverage. The thermoblock 3 can be brought into flow connection with the second chamber 5 for preparing the beverage, which has an opening 7 for pouring the prepared beverage.
Između termoblokova 3r4 i komora 5, 6 za pripremu napitka postoje, respektivno, spregnuti nepovratni ventili 39, 40. Ovi nepovratni ventili 39, 40 sprečavaju svako prottcanje tećnosti iz komora za pripremu napitka 5, 6 nazad prema termoblokovima 3, •4 Praticartje tećnosti iz termoblokova 3, 4 prema komorama 5, 6 za pripremu napitka se prvenstveno dešava samo nakon što pritisak postane veći od đefinisanog praga pritiska, gde se prag nivoa pritiska određuje pomoću sprežne sile kojom opruga deluje na zatvarače ventila 39,40. Between the thermoblocks 3r4 and the chambers 5, 6 for the preparation of the beverage there are, respectively, coupled non-return valves 39, 40. These non-return valves 39, 40 prevent any flow of liquid from the chambers for the preparation of the beverage 5, 6 back towards the thermoblocks 3, •4 The flow of liquid from the thermoblocks 3, 4 towards the chambers 5, 6 for the preparation of the beverage primarily occurs only after the pressure becomes greater than defined pressure threshold, where the pressure level threshold is determined by the coupling force with which the spring acts on the valve closures 39,40.
Svaka od komora za pripremu napitka je izvedena tako da može da prihvati sastojke od kojih se priprema napitak, odnosno tečna jestiva namirnica. Each of the chambers for the preparation of the beverage is designed so that it can accept the ingredients from which the beverage is prepared, i.e. liquid edible food.
Obe ulazne strane, ulazna strana 23 termobloka 4 i ulazna strana 24 termobloka 3, mogu se selektivno dovesti u protočnu vezu sa otvorima 13, 12 za pražnjenje respektivno. pomoću aktivno upravljanih ventila 16. 17 kada su oni u svojim otvorenim stanjima. Both inlet sides, inlet side 23 of thermoblock 4 and inlet side 24 of thermoblock 3, can be selectively brought into flow connection with discharge openings 13, 12 respectively. by means of actively controlled valves 16. 17 when they are in their open states.
Upravljanje ventilima 16, 17 se može izvesti npr. pomoću elektronskog upravljačkog sredstva (mikroprocesora i si.), što će biti opisano kasnije u vezi sa Slikom 2. Pražnjenje se može izvoditi automatski periodično, npr. nakon isteka određenog vremenskog perioda. The control of valves 16, 17 can be carried out, for example. by means of an electronic control means (microprocessor, etc.), which will be described later in connection with Figure 2. Discharge can be performed automatically periodically, e.g. after a certain period of time.
Voda se iz prvog rezervoara 1 može dovesti pod pritisak pomoću dodatne pumpe 33, pomoću koje se voda pod pritiskom dovodi do opcionog termobloka 10 za proizvodnju pare. The water from the first tank 1 can be pressurized using an additional pump 33, by means of which the pressurized water is supplied to the optional thermoblock 10 for steam production.
Izlazna strana termobloka 10 za proizvodnju pare se može selektivno dovesti u protočnu vezu sa piskom 11 za paru kada se aktivno upravlja ventilom 34 u njegovom otvorenom stanju. The outlet side of the steam generating thermoblock 10 can be selectively brought into flow communication with the steam nozzle 11 when the valve 34 is actively operated in its open state.
Dodatno, ulazna strana 22 termobloka 10 se može selektivno dovesti u protočnu vezu sa (opcionim) sredstvom 15 za kondenzaciju tako da je ulazna strana 22 termobloka 10 za proizvodnju pare u protočnoj vezi sa otvorom 21 za pražnjenje. In addition, the inlet side 22 of the thermoblock 10 can be selectively brought into flow communication with the (optional) condensing means 15 so that the inlet side 22 of the thermoblock 10 for producing steam is in flow communication with the discharge port 21 .
U ovom cilju, ventil 18 za pražnjenje se može aktivnim putem otvoriti i držati u svom otvorenom stanju. To this end, the discharge valve 18 can be actively opened and held in its open state.
Kako je već ranije opisano, svaki od termoblokova 3 i 4 se može upotrebiti za dovođenje vrele vode pod pritiskom (nezavisno jedan od drugog) do komora 5 i 6 za pripremu napitka, respektivno. Dodatno, izlazni otvori termoblokova 3, 4 se selektivno mogu dovesti u protočnu vezu sa zajedničkim otvorom 14 za točenje vrele vode, gde u ovom smislu između izlazne strane termoblokova 3, 4 i zajedničkog otvora 14 za točenje vrele vode postoje upravljačka sredstva, tj. ventili 19, 20. As already described earlier, each of the thermoblocks 3 and 4 can be used to supply hot water under pressure (independently of each other) to the chambers 5 and 6 for the preparation of the beverage, respectively. Additionally, the outlet openings of the thermoblocks 3, 4 can be selectively brought into flow connection with the common opening 14 for dispensing hot water, where in this sense there are control means between the outlet side of the thermoblocks 3, 4 and the common opening 14 for dispensing hot water, i.e. valves 19, 20.
Kao što je prikazano na Slici 2felektronsko upravljačko sredstvo, kao što je na primer mikroprocesor, upravlja radom termoblokova (zagrevanjem), pumpama, kao i radom različitih ventila prikazanih na Slici 1. As shown in Figure 2, an electronic control device, such as a microprocessor, controls the operation of thermoblocks (heating), pumps, as well as the operation of the various valves shown in Figure 1.
Sredstva 35 za upravljanje mogu posedovati signale 37 za praćenje statusa pomoću kojih se na pogodan način prati trenutno stanje različitih elemenata uređaja 9 za pripremu napitaka, prikazanog na Slici 1, gde su signali 37 generisani pomoću pogodnih senzorskih sredstava. Ovi signali 37 za praćenje statusa mogu predstavljati npr. temperature termoblokova, stanje protoka tećnosti dobijeno od strane merača protoka, nivo pritiska na sekundarnoj strani pumpi, kao i nivo vode u rezervoarima 1, 2. The control means 35 can have status monitoring signals 37 by means of which the current state of the various elements of the beverage preparation device 9 shown in Figure 1 is conveniently monitored, where the signals 37 are generated by suitable sensor means. These status monitoring signals 37 can represent e.g. temperature of the thermoblocks, the state of the liquid flow obtained by the flow meter, the pressure level on the secondary side of the pump, as well as the water level in tanks 1, 2.
Funkcionisanjem uređaja 9 za pripremu napitaka prikazanog na Slici 1 se može upcatfjaft pomoću korisničkog tnterfejsa 36 preko kojeg korisnik može odabrati način funkćionisanja uređaja za pripremu napitaka. Korisnički interfejs 36 može takođe posedovati sredstva za prikaz trenutnog statusa uređaja 9 za pripremu napitaka. The functioning of the beverage preparation device 9 shown in Figure 1 can be downloaded using the user interface 36 through which the user can select the mode of functioning of the beverage preparation device. The user interface 36 may also have means for displaying the current status of the beverage preparation device 9 .
Uređaj 9 za pripremu napitaka, kakav je prikazan na Slici 1, poseduje naprednu fleksibilnost zbog prozvoda koji se mogu dobiti na različitim otvorima za točenje: Kako su nezavisni termoblokovi 3, 4 povezani respektivno sa komorama 5. 6 za pripremu napitka, istovremeno se mogu pripremati, odnosno točiti sa otvora 7. 8 za točenje, dva različita napitka. The device 9 for the preparation of beverages, as shown in Figure 1, has advanced flexibility due to the products that can be obtained at different pouring openings: As the independent thermoblocks 3, 4 are connected respectively to the chambers 5. 6 for the preparation of the beverage, two different beverages can be simultaneously prepared, that is, poured from the opening 7. 8 for pouring.
Dalje, kako svaki od termoblokova 3, 4 može selektivno biti u vezi sa zajedničkim otvorom 14 za točenje vrele vode, simultano se sa jednog od otvora 7. 8 za točenje napitka može točiti pripremljeni napitak, dok se iz otvora 14 za točenje može dobijati vrela voda. Further, as each of the thermoblocks 3, 4 can be selectively connected to the common opening 14 for pouring hot water, a prepared beverage can be poured simultaneously from one of the openings 7, 8 for pouring the beverage, while hot water can be obtained from the opening 14 for pouring.
U ovom smislu, upravljačko sredstvo 35, prikazano na Slici 2, odlučuje da ti se jedan od termoblokova 3, 4 trenutno ne koristi za dovođenje vrele vode pod pritiskom do komore za pripremu napitka, i zatim dovodi bilo koji neupotrebljeni termoblok 3. 4 u protočnu vezu sa zajedničkim otvorom 14 za točenje vrele vode pomoću aktivno upravljanih ventila 19 i 20, respektivno. U slučaju da nijedan od termoblokova 3, 4 trenutno nije u upotrebi radi pripreme napitka, oba termobloka 3, 4 se mogu dovesti u protočnu vezu sa zajedničkim otvorom 14 za točenje vrele vode, čime se povećava efektivni protok vrele vode na otvoru 14. In this sense, the control means 35, shown in Figure 2, decides that one of the thermoblocks 3, 4 is not currently being used to supply hot water under pressure to the beverage preparation chamber, and then brings any unused thermoblock 3, 4 into flow connection with the common opening 14 for dispensing hot water by means of actively controlled valves 19 and 20, respectively. In the event that none of the thermoblocks 3, 4 is currently in use for the preparation of a beverage, both thermoblocks 3, 4 can be brought into flow connection with the common opening 14 for dispensing hot water, thereby increasing the effective flow of hot water at the opening 14.
Kako je već ukratko opisano u prethodnom tekstu, jedan od termoblokova 3. 4 za pripremu napitaka kao i termoblok 10 za proizvodnju pare se mogu isprazniti, prvenstveno sa svojih ulaznih strana 22,23 i 24, respektivno. As already briefly described in the previous text, one of the thermoblocks 3, 4 for the preparation of beverages as well as the thermoblock 10 for the production of steam can be emptied, primarily from their entrance sides 22, 23 and 24, respectively.
Uopšteno, pražnjenje, odnosno evakuacija termoblokova se vrši kako bi se smanjila količina nataloženih supstanci u krivinama unutar termobloka. Evakuacija se na primer može inicirati nakon što termoblok nije bio u upotrebi u toku nekog predefin'tsanog vremenskog perioda. In general, emptying or evacuation of thermoblocks is done in order to reduce the amount of deposited substances in the bends inside the thermoblock. Evacuation can, for example, be initiated after the thermoblock has not been in use for a predefined period of time.
Prema pronalasku, pražnjenje termoblokova se prvenstveno izvodi sa ulaznih strana 22, 23 i 24. respektivno, otvaranjem ventila 16, 17, 18, respektivno. Kako bi se obezbedio ispravan protok evakuisane vode na ulaznim stranama, na izlaznim stranama termoblokova 3,4 se respektivno može formirati „odušak" otvaranjem pridruženih ventila na izlaznim stranama, na primer otvaranjem najmanje jednog od ventila 19 i 20. Na ovaj način se omogućava da se vazduh usisava u unutrašnjost termoblokova 3, 4 iz otvora 14 za točenje vrele vode. Pronalazač je zaključio da je sa praktične strane efikasnije da se prilikom pražnjenja termoblokova sa njihovih ulaznih strana, istovremeno uvodi vazduh sa izlaznih strana odgovarajućeg termobloka. According to the invention, the discharge of the thermoblocks is primarily carried out from the inlet sides 22, 23 and 24, respectively, by opening the valves 16, 17, 18, respectively. In order to ensure the correct flow of evacuated water on the inlet sides, a "vent" can be formed on the outlet sides of the thermoblocks 3, 4, respectively, by opening the associated valves on the outlet sides, for example by opening at least one of the valves 19 and 20. In this way, it is possible to suck air into the interior of the thermoblocks 3, 4 from the opening 14 for dispensing hot water. The inventor concluded that, from a practical point of view, it is more efficient to simultaneously introduce air from the outlet sides of the corresponding thermoblock when emptying the thermoblocks from their inlet sides.
U svakom slučaju, protok tećnosti prilikom pražnjenja termoblokova će biti podstaknut silom gravitacije. U ovom smislu, otvori za pražnjenje (a samim tim i posuda 41, 42 za prikupljanje kapajuće tećnosti) se nalaze na nižoj poziciji u odnosu na ulazne strane termoblokova čija se pražnjenje vrši. In any case, the flow of liquid during the discharge of thermoblocks will be encouraged by the force of gravity. In this sense, the openings for emptying (and therefore the container 41, 42 for collecting the dripping liquid) are located at a lower position in relation to the inlet sides of the thermoblocks whose emptying is carried out.
Dalji aspekt predmetnog pronalaska se odnosi na proizvodnju pare koja se vrši pomoću opcionog termobloka 10 za proizvodnju pare. Kada se inicira operacija proizvodnje pare, na početku će sredstvo 35 za upravljanje, kao stoje prikazano na Slici 2, aktivnim putem otvoriti ventil 18 tako da se ulazna strana 22 termobloka 10 dovede u protočnu vezu sa opcionim kondenzatorom 15 i posudom 21 za prikupljanje kapajuće tećnosti radi pražnjenja ulazne strane 22 termobloka 10 za proizvodnju pare. Nakon što je ispunjen predefinisani kriterijum, sredstvo za upravljanje će dozvoliti da se ventil 18 zatvori i istovremeno će aktivnim putem otvoriti ventil 34 tako da može započeti proizvodnja pare. Para će, konačno, biti raspoloživa na pisku 11 za paru. A further aspect of the present invention relates to the production of steam, which is carried out by means of the optional thermoblock 10 for the production of steam. When the steam production operation is initiated, initially the control means 35, as shown in Figure 2, will actively open the valve 18 so that the inlet side 22 of the thermoblock 10 is brought into flow connection with the optional condenser 15 and the container 21 for collecting the dripping liquid in order to discharge the inlet side 22 of the thermoblock 10 for steam production. After the predefined criterion is met, the control means will allow the valve 18 to close and simultaneously open the valve 34 in an active way so that steam production can begin. Steam will finally be available on the 11th for steam.
Treba primetiti da predefinisani kriterijum može, na primer, biti određeni vremenski period od započinjanja procesa proizvodnje pare i/ili vrednost praga temperature. Dok god nije istekao vremenski period Viti termoblok 10 nije još dostigao temperaturu praga, ulazna strana će biti u svom stanju pražnjenja dok će izlazna strana, tj. ventil 34, biti zatvorena. Stoga, tokom zagrevanja termobloka 10 za proizvodnju pare neće doći do isticanja vode kroz pisak 1 i za paru. Tek nakon što je završeno zagrevanje termobloka 10 za proizvodnju pare, ispravna količina (zapremina) pare na tačno definisanoj temperaturi će biti isporučena kroz pisak 11 za paru. It should be noted that the predefined criterion can, for example, be a certain time period from the start of the steam production process and/or a temperature threshold value. As long as the time period of Viti thermoblock 10 has not yet reached the threshold temperature, the input side will be in its discharge state, while the output side, i.e. valve 34, be closed. Therefore, during the heating of the thermoblock 10 for the production of steam, water will not flow through the spout 1 and for steam. Only after the heating of the thermoblock 10 for steam production is completed, the correct amount (volume) of steam at a precisely defined temperature will be delivered through the steam nozzle 11.
Tipična vrednost temperature praga može biti, na primer, 100 do t05<=>C i samo nakon što temperatura termobloka 10 dostigne takvu vrednost praga, zatvoriće se ventil 18 i sistem za proizvodnju pare će biti spreman za upotrebu. Temperatura se može meriti na primer upotrebom NTC elementa. A typical value of the threshold temperature can be, for example, 100 to t05<=>C and only after the temperature of the thermoblock 10 reaches such a threshold value, the valve 18 will be closed and the steam production system will be ready for use. The temperature can be measured for example using an NTC element.
Iz prethodnog je jasno da ventil 18 služi kao ventil za pražnjenje termobloka 10 za proizvodnju pare. Tokom ovog perioda zagrevanja, ovaj ventil 18 je aktivno kontrolisan u svojem otvorenom stanju. Sa druge strane, jednom kada je termoblok 10 dostigao punu funkcionalnost za proizvodnju pare, ventil 18 se nalazi u zatvorenom položaju. VJ ovom stanju on može služiti i kao ventil za zaštitu od prevelikog pritiska tako da se i pasivno može otvoriti ukoliko pritisak unutar termobloka 10 prekorači određenu vrednost praga., usled čega se nad-pritisak pare iz termobloka 10 može ispustiti u posudu 41 za prikupljanje kapajuće tećnosti. It is clear from the above that the valve 18 serves as a discharge valve for the thermoblock 10 for steam production. During this warm-up period, this valve 18 is actively controlled in its open state. On the other hand, once the thermoblock 10 has reached full steam production functionality, the valve 18 is in the closed position. In this state, it can also serve as a valve for protection against excessive pressure, so that it can also be opened passively if the pressure inside the thermoblock 10 exceeds a certain threshold value, as a result of which the overpressure of the steam from the thermoblock 10 can be released into the container 41 for collecting the dripping liquid.
Tokom rada termoblok 10 neće biti pražnjen niti će u njega biti uveden vazduh (nasuprot termoblokova koji su povezani sa komorama za pripremu napitka). Vrela para uvek ostaje unutar termobloka 10 tako da je ona po potrebi na raspolaganju u svakom trenutku. During operation, the thermoblock 10 will not be emptied nor will air be introduced into it (as opposed to thermoblocks connected to the chambers for preparing the beverage). The hot steam always remains inside the thermoblock 10 so that it is available at any time if needed.
U termoblok 10 će biti uveden vazduh samo na početku procesa pripreme pare. Ovo se vrši kako bi se tzbeglo da bilo kakvo usisavanje vode i kondenzacija unutar termobloka 10 po njegovom hlađenju (nakon što je isključen), dovede do proizvodnje neželjene prekomerne pare. Air will be introduced into the thermoblock 10 only at the beginning of the steam preparation process. This is done to avoid any water suction and condensation inside the thermoblock 10 after it cools down (after it has been switched off), leading to the production of unwanted excess steam.
U principu, moguće je proizvesti paru pomoću termobloka 10 nezavisno od bilo koje aktivnosti uređaja na pripremi napitka ili vrele vode koja bi se vršila u termobloku 4. Stoga se, u principu, proizvodnja pare može vršiti paralelno sa bilo kojom aktivnosti na pripremi napitka/napitka, napitka/vrele vode ili vrele vode (sa duplim protokom) u ostatku uređaja. In principle, it is possible to produce steam using the thermoblock 10 independently of any activity of the device on the preparation of a beverage or hot water that would be carried out in the thermoblock 4. Therefore, in principle, the production of steam can be carried out in parallel with any activity on the preparation of a beverage/drink, beverage/hot water or hot water (with double flow) in the rest of the device.
Sa druge strane, termoblok ima relativno veliku potrošnju energije (na primer 1100W), tako da ograničenja koja postoje po pitanju snage napajanja električnom energijom mogu dovesti do zahteva da se u isto vreme dozvoli upotreba samo dva od tri termobloka 3, 4 i 10, prikazanih na Slici 1. On the other hand, the thermoblock has a relatively high power consumption (for example 1100W), so the limitations that exist in terms of power supply power may lead to the requirement to allow the use of only two of the three thermoblocks 3, 4 and 10, shown in Figure 1, at the same time.
U slučaju da postoje takva ograničenja po pitanju snage napajanja električnom energijom, nakon što korisnik završi zadavanje operacije može se izvršiti: In the event that there are such restrictions on the power supply, after the user has finished setting the operation, the following can be performed:
- Priprema dva napitka pomoću dve komore za pripremu napitka, - Prepares two drinks using two chambers for preparing drinks,
