[001] Izgudrojums attiecas uz kafijas automātiem, jo īpašu uz kafijas automātiem ar piena padeves sistēmām.The invention relates to coffee machines, in particular to coffee machines with milk supply systems.

Zināmā tehnikas līmeņa analīzeAnalysis of the prior art

[002] Kafijas automāti ir automāti, kas sagatavo un izdod karstu kafiju un citus kafijas dzērienus. Vecāki modeļi izmantoja šķīstošo kafiju vai koncentrēta šķidruma kafiju un karstu vai verdošu ūdeni un nodrošināja piedevas, tādas kā krēms vai cukurs. Daži modernie automāti gatavo dažāda veida kafijas, tādas kā moka un latte, vai malto kafiju vai svaigi maltu kafiju, izmantojot automātā ierīkotas kafijas dzirnaviņas. Kafijas automātu piedāvātais piens ir no piena pulvera vai sausā piena.Coffee machines are machines that prepare and dispense hot coffee and other coffee beverages. Older models used instant coffee or concentrated liquid coffee and hot or boiling water and provided additives such as cream or sugar. Some modern vending machines make different types of coffee, such as mocha and latte, or ground coffee or freshly ground coffee, using the machine's built-in coffee grinder. The milk offered by the coffee machines is made from milk powder or milk powder.

[003] Pirmo automātu izgudroja Rudd-Melikian firma ASV 1947. gadā, kur produkts debitēja zem nosaukuma KwikKafe. Ап citas ASV firmas 1947. gadā sāka automātu ražošanu un jau 1955. gadā ASV eksistēja kādi 60 000 automāti. Mūsdienās kafijas automāti ir sastopami visā pasaulē.[003] The first machine was invented by the Rudd-Melikian company in the USA in 1947, where the product debuted under the name KwikKafe. Other US companies began manufacturing machines in 1947, and as early as 1955, there were some 60,000 machines in the United States. Today, coffee machines are found all over the world.

[004] ASV patenta publikācija Nr. US 8,635,944 un ASV patenta pieteikuma publikācija Nr. US 2011/0036244 izklāsta tipisku kafijas automātu konstrukcijas. Daudz jauninājumi ir kafijas pagatavošanas virzienā, bet ne svaiga piena nodrošināšanai.U.S. Patent Publication No. U.S. Patent No. 8,635,944 and U.S. Patent Application Publication No. US 2011/0036244 outlines the construction of a typical coffee machine. There are many innovations in the direction of coffee making, but not in the provision of fresh milk.

[005] ASV patenta publikācija Nr. US 9,016,189 izklāsta aparātu piena nodrošināšanai kafijas automātā, kas satur saldēšanas mezglu vai dzesēšanas kameru, kurā ir izvietots piena konteiners.U.S. Patent Publication No. U.S. Pat. No. 9,016,189 discloses an apparatus for supplying milk to a coffee machine comprising a refrigeration unit or a cooling chamber in which a milk container is located.

[006] Vairums no augstāk minētajiem kafijas automātiem nenodrošina piena padevi uz kafiju. Esošās piena sistēmas ir lielas un prasa sarežģītu apiešanos, lai iztīrītu piena padeves sistēmu.[006] Most of the above coffee machines do not provide milk to coffee. Existing milk systems are large and require complex handling to clean the milk supply system.

[007] Tādējādi ir nepieciešamas izveidot piena padeves sistēmu kafijas automātiem, kas ir viegli iebūvējama jau esošajos kafijas automātos, ir spējīga uzturēt pienu svaigu pietiekami ilgu laiku un ir viegla ekspluatācijā attiecībā uz drošumu un tīrību.Thus, it is necessary to provide a milk supply system for coffee machines which is easy to install in existing coffee machines, is able to keep the milk fresh for a sufficiently long time and is easy to operate in terms of safety and cleanliness.

Izgudrojuma izklāstsDETAILED DESCRIPTION OF THE INVENTION

The connecting element is connected to the milk supply pipe. The connecting element, like part of the milk supply pipe, is located in the cooling chamber. The system further comprises a milk valve connected to the milk supply pipe in the milk supply system to direct the flow of milk from the milk container through the milk supply pipe. The milk valve is also located in the cooling chamber. In another embodiment of the invention, the milk valve is connected to the connecting element or is part of the connecting element. The milk valve may be an electric valve or a mechanical valve, preferably a pressure relief valve. The function of the milk valve can also be performed by a pump which, when not in use, will keep the milk supply pipe closed and, when running, will allow the milk to flow from the milk container through the milk supply pipe. The outlet of the milk supply pipe is compatible with the milk preparation unit or with the coffee machine, ensuring that the milk is dispensed or poured into the coffee cup. The milk preparation unit can be any milk preparation unit known in the art.

[009] Piena padeves sistēma papildus satur ūdens-gaiss cauruli, kas savienota ar piena padeves cauruli ūdens un/vai gaisa padevei uz piena padeves cauruli minētās piena padeves caurules tīrīšanai pēc piena izdošanas.

[020] Metode piena padevei kafijas automātā satur sekojošus soļus.The method for feeding milk to a coffee machine comprises the following steps.

[021] Pirmais solis ietver piena nodrošināšanu ar piena konteinera palīdzību, kas atrodas dzesēšanas kamerā. Dzesēšanas kamerai ir durvis, caur kura piena konteiners tr ievietojams un izņemams no dzesēšanas kameras.[021] The first step involves providing the milk by means of a milk container located in the cooling chamber. The cooling chamber has a door through which the milk container tr can be inserted and removed from the cooling chamber.

[022] Otrais solis ietver piena padevi no piena konteinera caur piena padeves cauruli uz piena sagatavošanas bloku vai kafijas sagatavošanas bloku piena izdošanai servējamā krūzē. Padeve tiek vadīta ar piena vārsta palīdzību, kas selektīvi atveras un aizveras, kad ir izdots iepriekšnoteiktais piena daudzums.The second step involves feeding milk from a milk container through a milk supply pipe to a milk preparation unit or a coffee preparation unit for dispensing milk in a serving cup. The supply is controlled by a milk valve that selectively opens and closes when a predetermined amount of milk has been dispensed.

[023] Piena izdošanas process tiek pabeigts ar piena padeves apturēšanu, kas ir izdots iepriekšnoteiktais piena daudzums uz piena sagatavošanas bloku vai kafijas sagatavošanas bloku.[023] The milk dispensing process is completed by stopping the milk supply, which is a predetermined amount of milk dispensed onto the milk preparation unit or the coffee preparation unit.

Pirmais apakšsolis satur ūdens padevi uz piena padeves cauruli tādā veidā, ka piens, kas ir palicis piena padeves caurulē pēc piena padeves, tiek izskalots ārā no piena padeves caurules. Nākamais apakšsolis satur gaisa padevi uz piena padeves cauruli pēc ūdens padeves tādā veidā, ka ūdens, kas palika pēc ūdens padeves piena padeves caurulē iepriekšējā solī, tiek izskalots ārā no piena padeves caurules līdz tikai gaiss ir palicis piena padeves caurulē. Veidotā sistēma nodrošina vieglu minētās sistēmas tīrīšanu un iespēju izmantot pienu nevis piena pulveri kafijas automātā.[024] The method of cleaning a milk supply system, in particular a milk supply pipe, comprises the following sub-steps. The first sub-step contains the water supply to the milk supply pipe in such a way that the milk left in the milk supply pipe after the milk supply is flushed out of the milk supply pipe. The next sub-step contains the air supply to the milk supply pipe after the water supply in such a way that the water left after the water supply to the milk supply pipe in the previous step is flushed out of the milk supply pipe until only air remains in the milk supply pipe. The developed system provides easy cleaning of the system and the possibility to use milk instead of milk powder in the coffee machine.
