Description

ČISTILNA ROČKA ZA ČIŠČENJE FILTROV KAVNIH AVTOMATOVWASHING MACHINE FOR CLEANING FILTERS OF COFFEE MACHINES

Predmet izuma je čistilna ročka za čiščenje filtrov kavnih avtomatov, predvsem profesionalnih kavnih avtomatov.The object of the invention is a cleaning cleaner for filtering coffee machines, especially professional coffee machines.

Vsi večji kavni avtomati v restavracijah, kavarnah in drugih lokalih, kjer se na dan pripravi veliko število kav, imajo težave z rednim čiščenjem s kavnimi zrni umazanih kavnih avtomatov, predvsem kavnih filtrov. Redno čiščenje kavnih avtomatov je potrebno, ker se s tem zagotavlja čistoča kavnega filtra in s tem kvaliteten in vedno enak okus kave. Pri uporabi profesionalega kavnega aparata pri kuhanju kave ostane nekaj zrn zmlete kave na filtru in po robovih filtra. Če se ostankov zmlete kave redno ne odstranjuje s površine filtra in okoli filtra, se pri nepretrgani uporabi kavnega avtomata le-ti sčasoma zažgejo, kar povzroči, da ima kava grenak okus po zažgani kavi. Za zagotavljanje visoke kvalitete kave, bi se moral filter redno čistiti vsaj na vsakih petdeset pripravljenih kav.All major coffee machines in restaurants, cafes and other establishments where a large number of coffee is prepared daily have problems with regular cleaning with coffee beans of dirty coffee machines, especially coffee filters. Regular cleaning of coffee machines is necessary, as this ensures the cleanliness of the coffee filter and thus a quality and always the same taste of coffee. When using a professional coffee machine, when cooking coffee, some grains of ground coffee are left on the filter and along the edges of the filter. If the residue of ground coffee is not regularly removed from the filter surface and around the filter, the continuous use of the coffee machine will burn them over time, causing the coffee to taste bitter after burning coffee. To ensure high quality coffee, the filter should be cleaned regularly at least every fifty of prepared coffee.

Kavni filtri profesionalnih kavnih avtomatov so običajno sestavljeni iz glave, tesnila in mrežice. Pri kuhanju kave se na glavo natakne kavno ročko z zmletimi kavnimi zrni, z zasukom se kavno ročko preko zatičev, ki so izvedeni v zgornjem delu oboda, zatesni na tesnilo kavnega filtra in se skozi mrežico spusti vročo paro, ki potuje skozi zmleta kavna zrna. Pri tem del zmletih kavnih zrn ostane na mrežici in v prostoru okoli mrežice kamor se vstavi glava kavne ročke. Pri večkratni uporabi se ostanki zmletih kavnih zrn zažgejo, kar vpliva na grenak okus kave. Zato je potrebno kavne filtre redno čistiti. Čiščenje kavnega filtra se običajno izvaja ročno, tako da se filter najprej na notranji strani očisti z gobico, na glavo se natakne slepo ročko, to je slepo sito ali malo ročno kavno ščetko, nato pa se skozi filter spusti vroča para. Ne samo, da je tako čiščenje zamudno in nepopolno, pri ročnem čiščenju lahko pride tudi do poškodb delavca, ki čisti aparat. Pri čiščenju med uporabo lahko pride do opeklin, saj so deli kavnega aparata segreti na visoko temperaturo, od 80-90°C. Zato, da se preprečijo morebitne poškodbe, se čiščenje izvaja pri vsaj delno ohlajenem filtru, kar pomeni, da se kavni aparati v večini primerov čistijo enkrat dnevno, na koncu obratovalnega časa lokala, saj se takrat aparat dovolj ohladi.Coffee filters of professional coffee machines are usually made up of heads, gaskets and grids. When cooking coffee, a coffee mug with ground coffee beans is placed on top of the head, the coffee spoon is turned through the pins carried in the upper part of the rim, sealed onto the coffee filter seal, and a hot steam passing through the ground coffee beans drops through the net. In this case, a portion of ground coffee beans remains on the mesh and in the room around the net where the head of the coffee handle is inserted. When used repeatedly, the residue of ground coffee beans is burnt, which affects the bitter taste of coffee. Therefore, the coffee filters should be cleaned regularly. Cleaning the coffee filter is usually done manually so that the filter is first cleaned on the inside with a sponge, a blind hand is placed on the head, a blank sieve or a small hand-made coffee brush, and then the hot steam passes through the filter. Not only is this cleaning time-consuming and incomplete, manual cleaning can result in damage to the worker who is cleaning the appliance. Burns may occur during cleaning during use, as the parts of the coffee machine are heated to a high temperature of 80-90 ° C. In order to prevent possible damage, the cleaning is carried out at least partially cooled filter, which means that in most cases coffee machines are cleaned once a day, at the end of the operating time of the bar, as the appliance is then cooled sufficiently.

Navedene pomanjkljivost so odpravljene s čistilno ročko za čiščenje filtrov kavnih avtomatov po izumu. Čistilna ročka po izumu se prilega vsakokratnemu nastavku kavnega avtomata in je po obliki enaka kavni ročki profesionalnega kavnega avtomata za kuhanje kave. Sestavljena je iz natične glave in ročaja, ki se nahajata v ohišju. Čistilno ročko se pritrdi oziroma namesti na kavni avtomat na enak način kot se namestijo kavne ročke pri pripravi kave in sicer se na glavo kavnega filtra natakne čistilno ročko in se jo z zasukom preko tesnila zatesni na glavo.This defect is corrected by a cleaning handle for cleaning the filters of coffee machines according to the invention. The cleaning arm according to the invention fits in with each extension of the coffee machine and is shaped like a coffee cup of a professional coffee machine. It consists of a pin head and a handle, which are located in the housing. The cleaning handle is fixed or installed on the coffee machine in the same way as the coffee spoons are placed in the preparation of the coffee, and the cleaning handle is placed on the head of the coffee filter and sealed by the seal through the seal on the head.

Natična glava vključuje os na katero je pritrjena krtačka s posebej oblikovanimi ščetinami, ki zagotavljajo naleganje na filter in doseganje vseh površin filtra, ki jih je potrebno očistiti. Izraz ščetina vključuje v kontekstu patentne prijave eno ščetino ali več ščetin povezanih v šop ščetin. V ročaju je nameščeno pogonsko sredstvo za vrtenje krtačke. V prednostni izvedbi je pogonsko sredstvo elektromotor in baterija, ki služi za pogon elektromotorja. Ko se čistilna ročka vključi, se začne krtačka s ščetinami vrteti, pri čemer ščetine dosežejo vse ključne površine filtra in jih očistijo. Hkrati z vključitvijo ročke se na kavnem avtomatu pritisne gumb, da skozi filter steče vroča voda, ki splakne nečistoče, ki jih je krtačka zdrgnila s filtra, in čiščenje je opravljeno v manj kot minuti.The tip head includes an axle on which a brush is attached with specially shaped bristles, which ensure that the filter is filtered and the reach of all the surfaces of the filter to be cleaned. The term bristle includes one bristle or more bristles connected to the bristle bristles in the context of the patent application. A handle for rotating the brush is mounted in the handle. In the preferred embodiment, the drive means is an electric motor and a battery that serves to drive an electric motor. When the cleaning arm is turned on, a brush with a bristle starts to rotate, with the bristles reaching all the key surfaces of the filter and clearing them. At the same time, when the handle is switched on, a button is pressed on the coffee machine to get hot water through the filter, which rinses impurities brushed by the brush from the filter, and the cleaning is done in less than a minute.

Izum bo opisan na izvedbenem primeru in s pomočjo slik, ki prikazujejo: slika 1 prikazuje prerez čistilne ročke za čiščenje kavnih avtomatov po izumu, ki je nameščena v glavo kavnega filtra; slika 2 prikazuje prerez kavnega filtra in krtačke; slika 3 prikazuje prerez stika, ko je glava čistilne ročke nameščena v glavo kavnega filtra:The invention will be described on the embodiment and with the help of illustrations: Fig. 1 shows a cross-section of a cleaning handle for cleaning coffee machines according to the invention, which is placed in the coffee filter head; Figure 2 shows the cross-section of the coffee filter and the brush; Figure 3 shows the cross-section of the contact when the head of the cleaning handle is placed in the coffee filter head:

Slika 4 prikazuje prerez izvedbenih variant krtačke.Figure 4 shows a cross section of the brush variants.

Ročka po izumu, ki je predstavljena na slikah, je sestavljena iz natične glave 2 in ročaja 3, pri čemer se oba nahajata v ohišju 1. Ohišje 1 je v območju natične glave 2 oblikovano kot votlo telo, ki ima v vzdolžnem prerezu obliko kolobarja z zunanjim premerom D1 in notranjim premerom D3, pri čemer se ohišje 1 s svojim zunanjim premerom D1 dimenzijsko prilega vsakokratnemu nastavku kavnega avtomata. Zunanji premer D1 ohišja 1 je tako enak vsakokratnemu premeru D2 odprtine kavnega filtra, v katero se vstavi ročko.The handle according to the invention, which is depicted in the figures, is composed of a pin head 2 and a handle 3, both of which are in the housing 1. The housing 1 is formed in the region of the pin head 2 as a hollow body, which, in the longitudinal cross-section, has the shape of a ring with with an outer diameter D1 and an internal diameter D3, wherein the housing 1 with its outer diameter D1 dimensionally fits to the respective extension of the coffee machine. The outer diameter D1 of the housing 1 is thus equal to the respective diameter of the coffee cup opening D2 to which the handle is inserted.

Na zunanji steni ohišja 1 v območju natične glave 2 so v zgornjem delu oboda izvedeni zatiči za pritrditev na nastavek kavnega avtomata (na sliki niso prikazani), to je na glavo 4 kavnega filtra, na enak način kot so izvedeni zatiči pri standardni kavni ročki. Ko se ročko po izumu namesti na glavo 4 kavnega filtra, zgornji del ohišja 1 v predelu natične glave 2 s svojo zunanjo površino nalega na notranjo površino glave 4 kavnega avtomata, s svojim zgornjim robom pa nalega na tesnilo 4.1 kavnega filtra. V spodnjem delu ohišja 1 v območju natične glave 2 je na ohišje 1 fiksirana os 13 na katero je centrično in vrtljivo nameščena krtačka 5. V izvedbenem primeru je os 13 na ohišje 1 fiksirana z vijačno zvezo. Krtačka 5 je sestavljena iz podstavka 6 in ščetin 7, ki so pritrjene na podstavek 6, pri čemer je podstavek 6 na znane načine povezan s pogonskim sredstvom 9, ki se nahaja v notranjosti ohišja 1, prednostno v predelu ročaja 3, tako da je omogočeno vrtenje krtačke 5. V izvedbenem primeru je vrtenje krtačke 5, oziroma podstavka 6 izvedeno preko dveh zobnikov 10, 11 in elektromotorja 9, ki ga poganja baterija 20. Zobnik 11 je pritrjen na gred elektromotorja 9, zobnik 10 pa je povezan s podstavkom 6 krtačke 5. Podstavek 6 je fiksiran na zobnik 10 preko zatiča 14, ki se usede v utor izveden na zobniku 10. Da podstavek 6 ne izpade, je zagotovljeno z o-tesnilom 16, ki leži v utoru med podstavkom 6 in zobnikom 10. Zobje zobnikov 10 in 11 se ujemajo in zobnik 11 preko zobnika 10 poganja krtačko 5. Zobnik 10 je v vertikalni smeri uležajen na puši 17, rotacijsko pa z ležajem 18 na nosilec 19. Na nosilec 19 pritiska vzmetni element 15 in omogoča primerno silo pritiska podstavka 6 s ščetinami 7 krtačke 5 na čiščene površine filtra. Zobnik 10 ima zobe v aksialni smeri večje višine kot zobnik 11 tako, da se zobje obeh zobnikov 10, 11 ujemajo tudi ko se zobnik 10 giblje v aksialni smeri.On the outer wall of the housing 1 in the area of the header 2, the pins for fastening to the cup of the coffee machine are carried out in the upper part of the periphery (not shown in the figure), that is, on the head of the 4 coffee filter in the same manner as the pins in the standard coffee handle. When the handle according to the invention is placed on the head of the 4 coffee filter, the upper part of the housing 1 in the part of the squeegee 2 with its outer surface fits on the inner surface of the head of the 4 coffee machine, and with its upper edge it rests on the sealer 4.1 of the coffee filter. In the lower part of the housing 1 in the area of the header head 2, the housing 1 is a fixed axle 13 to which the brush 5 is mounted centrically and rotatably. In the embodiment, the axis 13 is fixed to the housing 1 by a screw connection. The brush 5 is comprised of base 6 and bristles 7 which are attached to the base 6, the base 6 being known in a known manner by means of the driving means 9 which is located inside the casing 1, preferably in the handle section 3, so that it is possible rotation of the brush 5. In the embodiment, rotation of the brush 5 or the base 6 is carried out over two gears 10, 11 and an electric motor 9 driven by the battery 20. The gears 11 is attached to the shaft of the electric motor 9 and the gears 10 are connected to the brush base 6, 5. The base 6 is fixed to the pinion 10 via the pin 14 which is seated in the groove carried out on the pinion 10. The base 6 is not disengaged, it is provided with an o-seal 16 lying in the groove between the base 6 and the pinion 10. The teeth of the gears 10 and 11 match and the pinion 11 drives the brush 11 through the sprocket 10. The pinion 10 is mounted in a vertical direction on the sleeve 17 and rotated by the bearing 18 on the carrier 19. The spring 19 presses the spring element 15 and provides the appropriate force of the pressure of the base 6 with bristles 7 brush 5 on the filtered surface of the filter. The pinion 10 has teeth in the axial direction of a higher height than the gear 11, so that the teeth of the two gears 10, 11 match also when the gear 10 moves in the axial direction.

Premer D5 podstavka 6 je manjši od notranjega premera D3 ohišja 1, zato da je omogočeno vrtenje podstavka 6 oziroma krtačke 5 znotraj ohišja 1 v predelu natične glave 2. Pri tem se med robom podstavka 6 in notranjo površino ohišja 1 v predelu natične glave 2 formira reža 6a, ki dodatno služi za odtekanje vode. Voda tako odteka po zunanjem robu podstavka 6, skozi režo 6a med podstavkom 6 in ohišjem 1, v vsaj en odvodni kanal 12, ki je izveden v ohišju 1 v predelu natične glave 2.The diameter D5 of the base 6 is smaller than the inner diameter D3 of the housing 1 in order to allow rotation of the base 6 and the brush 5 inside the housing 1 in the region of the header 2. In this case, between the edge of the base 6 and the inner surface of the housing 1 in the region of the pin head 2, slot 6a, which additionally serves to drain water. The water thus flows out the outer edge of the base 6 through the slot 6a between the base 6 and the housing 1 into at least one drainage channel 12 which is carried out in the housing 1 in the blade head portion 2.

Krtačka 5 vsebuje vsaj en set kratkih ščetin 7.1, ki so pritrjene na podstavek 6 tako, da je na določenem radiju od osi 13 vsaj ena kratka ščetina 7.1, s čimer dosežemo da ob vrtenju krtačke 5 kratke ščetine 7.1 dosežejo celotno površino mrežice 4.2 filtra in v času delovanja potujejo preko celotne površine mrežice 4.2 filtra. To pomeni, da so posamezne kratke ščetine 7.1 iz seta lahko poljubno razporejene po površini podstavka 6, vendar mora njihova razporeditev zagotavljati, da ob vrtenju krtačke 5 kratke ščetine 7.1 dosežejo celotno površino mrežice 4.2 filtra. Ker je potrebno poleg mrežice 4.2 filtra očistiti tudi prostor 8 okoli mrežice 4.2 filtra, v katerega se vstavi natična glava 2, vsebuje krtačka 5 dodatno vsaj eno dolgo ščetino 7.2, ki je pritrjena na zgornjo površino podstavka 6 ob njegovem zunanjem obodu tako, da ob namestitvi čistilne ročke na glavo 4 kavnega filtra dolga ščetina 7.2 naleže v prostor 8 okoli mrežice 4.2 filtra. Ščetine 7 krtačke 5 so obrnjene navzgor, torej v smeri kavnega avtomata. V prednostni izvedbi so dolge ščetine 7.2 v enakomernih razmikih ena od druge razporejene ob celotnem zunanjem obodu podstavka 6, kratke ščetine 7.1 pa so v koncentričnih krogih v enakomernih razmikih razporejene po preostali površini podstavka 6, to je v območju površine podstavka 6, ki se nahaja pod površino mrežice 4.2 filtra. Ščetine 7 so na znane načine fiksno pritrjene na zgornjio površino podstavka 6, to je na površino, ki je obrnjena proti kavnemu filtru, na primer na način kot so pritrjene ščetine pri zobni ščetki. Kratke ščetine 7.1 so prednostno pritrjene pravokotno glede na ravnino podstavka 6, to je v smeri osi 13. Dolge ščetine 7.2 so pritrjene pod kotom a, tako da so glede na os 13 nagnjene navzen, to je stran od osi 13, ali navznoter, to je proti osi 13. Kot a je med 0° in 25°. V prednostni izvedbi so dolge ščetine 7.2 pritrjene pod kotom navzven, tako da s svojim zgornjim delom segajo za 1 do 3 mm preko roba podstavka 6. V primeru, ko so dolge ščetine 7.2 pritrjene pod kotom navzven, je zgornji del ohišja 1 v območju natične glave 2 izveden konusno. Notranji premer D3 ohišja 1 se zvezno manjša, tako da notranja površina zgornjega dela ohišja 1 v območju natične glave 2 sledi naklonskemu kotu dolgih ščetin 7.2 in je oblika prostora 8 v tem primeru tudi konusna.The brush 5 comprises at least one set of short bristles 7.1 which are attached to the base 6 such that at least one short bristle 7.1 on a given radius of axis 13 is achieved, thereby achieving the total area of the filter mesh 4.2 when the brush 5 of the short bristle is rotated during operation they travel across the entire surface of the mesh 4.2 filter. This means that the individual short bristles 7.1 from the set can be arbitrarily arranged over the surface of the base 6, but their arrangement must ensure that when the brush rotates, the 5 short bristles 7.1 reach the entire surface of the mesh 4.2 filter. Since in addition to the filter mesh 4.2 it is also necessary to clean the space 8 around the mesh 4.2 of the filter into which the insertion head 2 is inserted, the brush 5 additionally includes at least one long bristle 7.2 which is attached to the upper surface of the base 6 on its outer circumference, mounting the cleaning handle on the head 4 of the coffee filter, the long bristle 7.2 is placed in the space 8 around the filter mesh 4.2. The pins 7 of the brush 5 are facing upward, that is, in the direction of the coffee machine. In the preferred embodiment, the long bristles 7.2 are spaced uniformly apart from each other along the entire outer periphery of the base 6, and the short bristles 7.1 are arranged in concentric circles at regular intervals over the rest of the base 6, that is, in the area of the surface of the base 6 located below the surface of the mesh 4.2 filter. The bristles 7 are in a known manner fixedly fixed to the upper surface of the base 6, i.e. the surface facing the coffee filter, for example in a manner such that the bristles are attached to the toothbrush. The short bristles 7.1 are preferably fixed perpendicular to the plane of the base 6, i.e., in the direction of the axis 13. The long bristles 7.2 are fixed at an angle a so that, with respect to the axis 13, they are inclined, that is away from the axis 13 or inwards is against the axis 13. It is between 0 ° and 25 °. In the preferred embodiment, the long bristles 7.2 are attached at an angle to the outside, so that they extend by 1 to 3 mm over the edge of the base 6 with their upper part. In the case where the long bristles 7.2 are attached at an angle to the outside, the upper part of the housing 1 is in the region of the pin head 2 is conical. The inner diameter D3 of the housing 1 is continuously reduced so that the inner surface of the upper part of the housing 1 in the region of the pin head 2 follows the inclination angle of the long bristles 7.2, and the shape of the space 8 in this case is also conical.

Ob pritrditvi čistilne ročke na glavo 4 kavnega filtra morajo kratke ščetine 7.1 nalegati na mrežico 4.2 filtra. Pomik po osi 13, ki to zagotavlja, je izveden je lahko izveden na znane načine. V enem od izvedbenih primerov pomik po osi 13 zagotavlja vzmet 15, ki pritiska na nosilec 19. Vzmet 15 služi za prilagajanje sile, s katero pritiska krtačka 5 navzgor, to je na mrežico 4.2 filtra kavnega avtomata. V eni od izvedb je vzmet 15 lahko gumijast obroč. V notranjosti ohišja 1 se prednostno v predelu ročaja 3 nahaja pogonsko sredstvo 9, ki je v izvedbenem primeru elektromotor, ki ga poganja baterija 20. Na zgornji strani ohišja 1 je prednostno v predelu ročaja 3 izveden gumb 21 za vklop in izklop čistilne ročke. Opcijsko ima ročaj 3 na koncu v pokrovčku izveden nastavek 22 za napajanje, ki služi za polnjenje preko kabla, ali z odložitvijo v podstavek, to je v polnilno odložišče. Opcijsko je v zadnjem delu ročaja 3 nameščena LED lučka 23, ki indicira stanje baterije 20 in delovanje elektromotorja. Opcijsko se v notranjosti ohišja 1 lahko nahaja tudi timer, ki po preteku nastavljenega časa avtomatsko izključi vrtenje krtačke in z zvočnim signalom javi, da je cikel čiščenja končan. Opcijsko se v notranjosti ohišja 1 v predelu ročaja 3 lahko nahaja logično krmilno vezje 24, ki beleži in shranjuje podatke iz naprave v odvisnosti od časa, na primer ali je bila ročka v uporabi, kolikokrat je bila v uporabi, povprečen čas uporabe ročke, in podobno, in omogoča povezavo in prenos teh podatkov, na primer preko omerežja wi-fi, mobitelnega omrežja, v zunanje računalniško okolje, na primer v spletni oblak ali v mobilni telefon.When the cleaning handles are attached to the head of the 4 coffee filter, the short bristles 7.1 must be placed on the 4.2 filter mesh. The shift along the axis 13, which provides this, is performed can be carried out in known ways. In one embodiment, the shift along the axis 13 provides a spring 15 which presses the carrier 19. The spring 15 serves for adjusting the force by pressing the brush 5 upward, that is to the grinder 4.2 filter cartridge. In one embodiment, the spring 15 may be a rubber ring. In the interior of the housing 1, preferably in the handle area 3 there is a drive means 9, which is, in the embodiment, an electric motor driven by a battery 20. On the upper side of the housing 1, a knob 21 for turning the washing arm on and off is preferably carried out in the handle area 3. Optionally, the handle 3 at the end of the cap performs a power supply 22 for charging via a cable, or by depositing it in the base, that is, in the filling clipboard. Optionally, in the rear of the handle 3, there is a LED 23 indicating the status of the battery 20 and the operation of the electric motor. Optionally, inside the housing 1, a timer can also be switched off automatically after the set time is set to turn the brush, and with an acoustic signal, the cleaning cycle is complete. Optionally, inside the housing 1 in the handlebar part 3, a logical control circuit 24 can be located that records and stores data from the device depending on the time, for example, whether the handgrip was in use, how many times it was in use, the average use time of the handle, and similarly, and enables the connection and transmission of this data, for example through a wi-fi network, a mobile network, into an external computing environment, such as an online cloud or a mobile phone.

Ročka po izumu deluje kot sledi: čistilno ročko se namesti na avtomat za kuhanje kave enako kot se namesti standardna ročka s kavo. Pri tem vzmet potisne podstavek s ščetinami proti mrežici filtra, tako da dolge ščetine naležejo v prostor okoli mrežice filtra, v katerega se vstavi natična glava, kratke ščetine pa nalegajo oziroma se dotikajo površine mrežice filtra. Z gumbom za vklop se zažene pogon ročke in krtačka se prične vrteti in s svojimi ščetinami drgne po površini mrežice filtra in po površini prostora. Hkrati je potrebno sprožiti kavni avtomat, tako da skozi filter kavnega avtomata steče voda, ki skozi odvodni kanal splakne nečistoče, ki jih je krtačka zdrgnila s filtra.The handle according to the invention acts as follows: the cleaning handle is placed on the coffee machine in the same way as the standard coffee maker is installed. In this spring, the spring pushes the bristle base to the filter net, so that the long bristles are placed in the space around the filter net in which the inserted head is inserted, and the short bristles attach or touch the surface of the filter net. The power button starts the handle of the handle and the brush begins to rotate and with its bristles rubs on the surface of the filter net and the surface of the room. At the same time, the coffee machine needs to be triggered, so that through the filter of the coffee machine, water flows through the drainage channel, which rinses the impurities brushed by the brush from the filter.
