Description
SAMODEJNI DOZIRNI SISTEM ZA DOZIRANJE PRALNEGA SREDSTVAAUTOMATIC DOSING SYSTEM FOR DETERGENT
[0001] Predlagani izum se nanaša na gospodinjski aparati, zlasti na pralni stroj za pranje perila, konkretno na doziranje pralnega sredstva v pralni prostor, kjer se izvaja pranje perila.The present invention relates to household appliances, in particular to a washing machine, in particular to the dosing of detergent into the laundry room where the laundry is performed.
[0002] Znani so pralni stroji, obsegajoči samodejni dozirni sistem za doziranje pralnega sredstva, pri katerih so rezervoarji za sprejem pralnega sredstva nameščeni bodisi v spodnjem delu pralnega stroja ali v predalu dozirne posode.Washing machines comprising an automatic detergent dosing system are known, in which the detergent receiving tanks are located either in the lower part of the washing machine or in the drawer of the dosing container.
[0003] V primeru, da je rezervoar za shranjevanje pralnega sredstva nameščen v spodnjem delu pralnega stroja, se polnjene le-tega izvaja preko predala dozirne posode, ki se ga izvleče in odpre pokrov, pod katerim se nahaja lijak, ki je s pomočjo cevi fluidno povezan z rezervoarjem. Nivo tekočega pralnega sredstva v rezervoarju se preverja s pomočjo senzorja nivoja in prikaže na uporabniškem vmesniku, kar zahteva krmiljenje omenjenega senzorja nivoja. Ker je potrebno v rezervoar integrirati kapo hidrostata, je zadevna rešitev izdelovalno zahtevna in cenovno neugodna. Zaradi prostorske omejitve je določena minimalna višina rezervoarja in posledično tudi volumen rezervoarja. Če uporabnik ne upošteva navodila o polnjenju rezervoarja, lahko zaradi tlačne preobremenitve pride do poškodbe oz. odpovedi delovanja senzorja nivoja.[0003] In the case where the detergent storage tank is located in the lower part of the washing machine, its filling is carried out through the drawer of the dosing container, which is pulled out and the lid under which the funnel is located is located, which is by means of a hose fluidly connected to the tank. The level of the liquid detergent in the tank is checked by means of a level sensor and displayed on the user interface, which requires the control of said level sensor. As it is necessary to integrate a hydrostat cap into the tank, the solution in question is production-demanding and cost-effective. Due to space constraints, the minimum tank height and consequently the tank volume are determined. If the user does not follow the instructions on filling the tank, the pressure overload can cause damage or. level sensor failure.
[0004] Poleg tega mora biti pralni stroj pred doziranjem pralnega sredstva vklopljen, da se prikaže pravilen položaj predala dozirne posode, kar je pogoj za pravilno doziranje pralnega sredstva v rezervoar in prikaz informacije na uporabniškem vmesniku o dosegu maksimalnega nivoja pralnega sredstva v rezervoarju. Če predal dozirne posode ni pravilno pozicioniran, steče pralno sredstvo neposredno v kad pralnega stroja in ne v rezervoar. Po končanem doziranju pralnega sredstva, je potrebno počakati vsaj 1 minuto, da pralno sredstvo popolnoma odteče v rezervoar in se nivo pralnega sredstva stabilizira.In addition, the washing machine must be switched on before dosing the detergent to show the correct position of the dosing drawer, which is a condition for correct dosing of the detergent into the tank and display information on the user interface on reaching the maximum level of detergent in the tank. If the dosing tank drawer is not positioned correctly, the detergent flows directly into the washing machine tub and not into the tank. After dosing the detergent, it is necessary to wait at least 1 minute for the detergent to drain completely into the tank and for the detergent level to stabilize.
[0005] V primeru, da je rezervoar za shranjevanje pralnega sredstva nameščen v predalu dozirne posode pralnega stroja, se polnjenje le-tega izvaja tako, da se predal izvleče in odpre pokrov, pod katerim se nahaja prostor za sprejem in shranjevanje pralnega sredstva. Nalivanje pralnega sredstva v rezervoar je v tem primeru oteženo zaradi sorazmerno majhne odprtine na zgornjem delu predala dozirne posode, zaradi česar prihaja do polivanja pralnega sredstva preko predala, po sprednji strani pralnega stroja in po tleh.[0005] In the case where the detergent storage tank is located in the drawer of the washing machine dosing container, it is filled by pulling out the drawer and opening the lid, under which the space for receiving and storing the detergent is located. Pouring detergent into the tank is difficult in this case due to the relatively small opening on the upper part of the dosing container drawer, which results in the detergent spilling over the drawer, on the front of the washing machine and on the floor.
[0006] Kadar je rezervoar integriran v predalu dozirne posode, nalivanje pralnega sredstva v rezervoar med delovanjem oz. med izvajanjem pralnega programa ni dovoljeno. Morebiten izvlek predala dozirne posode privede do razklopitve rezervoarja s črpalko, kar pa onemogoči doziranje pralnega sredstva v pralni boben.When the tank is integrated in the drawer of the dosing container, pouring the detergent into the tank during operation or. during the implementation of the washing program is not allowed. Any pulling out of the dosing drawer drawer causes the tank with the pump to disengage, which makes it impossible to dispense the detergent into the washing drum.
[0007] Naloga predlaganega izuma je ustvariti samodejni dozirni sistem za doziranje pralnega sredstva, s katerim so odpravljene pomanjkljivosti znanih rešitev.The object of the present invention is to provide an automatic dosing system for dosing detergent, which eliminates the shortcomings of the known solutions.
