Abstract

Vgradni kavni aparat je aparat, ki se ga uporablja v hišnem gospodinjstvu za pripravo kavnih napitkov. Nekatere izvedbe vgradnih aparatov imajo možnost priključka odvoda odpadne vode. Takšni tipi vgradnih aparatov so najvišjega cenovnega razreda, zato je pomembno, da priključek zagotavlja robustno odplako iz aparata. Trenutno se nahaja na aparatu sistem za odplakovanje s pomočjo prostega pada, ki pa ni zanesljiv, če aparat ni pravilno vgrajen. V okviru magistrske naloge smo razvili nov aktivni sistem za odplakovanje vode, ki bo potiskal vodo iz aparata ne glede na to, kako bo vgrajen. Na začetku razvojnega procesa smo definirali zahteve in funkcije, ki jih mora končna rešitev izpolnjevati. Izvedli smo proces iskanja glavnih in pomožnih funkcijskih principov, iz katerega smo dobili zasnove rešitev, ki smo jih združili v morfološko matriko. Sestavili smo kombinacije, ki so tvorile koncepte rešitev. Slednje smo vrednotili izkustveno in nato še eksperimentalno s prototipnimi rešitvami, s čimer smo dobili zmagovalno rešitev, za katero smo na koncu izdelali detajlni model. Zmagovalna rešitev razvojnega procesa je rešitev s peristaltično črpalko. Detajlni model označimo za funkcionalno rešitev, saj izpolnjuje vse vhodne zahteve, njena groba zasnova pa je primerna za serijsko proizvodnjo. Funkcionalna rešitev zagotavlja robustno in zanesljivo odplako vode iz aparata in rešuje problematiko obstoječega sistema.

Secondary title:	Development of an active drainage system for a built-in coffee machine
Secondary abstract:	A build-in coffee machine is a device used in households for preparation of coffee drinks. Some variants of build-in coffee machines, typically those of high-end class, have an option to connect to a house water drainage system. It is mandatory for those types of machines, to ensure a reliable water export out of the machine. Presently, the machine uses a passive drainage system on a free fall principle that works unreliably if the machine is not correctly installed. In this thesis we have developed a new active drainage system that should work properly regardless the installation. At the start of the development process, we defined requirements and functions, to which the end solution had to comply. We searched for main and auxiliary functional principles and created solution designs which were later collected into a morphological matrix. Combinations of solution designs were assembled into conceptual designs (concepts). Concepts were evaluated in two steps, firstly based on expertise and later with prototype testing. The goal was finding a winning solution, for which a detailed model was created. The winning solution of development process is the solution with a peristaltic pump. Detailed model is expressed as a functional solution due to its compliance with starting requirements, its rough design is suitable for series manufacturing. Functional solution offers robust and reliable water drain from coffee machine and resolves described issues of the existing system.
