Description

Pralni stroj z rezervoarjemWashing machine with tank

Predloženi izum se nanaša na področje pralnih strojev, konkretneje takšnih pralnih strojev, ki jim je prigrajen rezervoar za vodo, povsem konkretno pa na dovajanje vode v dozirno posodo.The present invention relates to the field of washing machines, more specifically to those washing machines to which a water tank is attached, and more specifically to the supply of water to a dosing vessel.

V posebnih primerih, npr. na področju, kjer je motena oskrba z vodo, je pralni stroj zasnovan tako, da mu je prigrajen rezervoar za vodo, v katerega uporabnik ročno nalije vodo, ki jo prinese npr. iz oddaljene lokacije. Tovrsten pralni stroj s pomočjo posebne črpalke med pranjem črpa vodo iz rezervoarja. Na dozirni posodi je zato zasnovan ustrezen mehanizem, ki pralno vodo usmerja v določen prekat. Omenjeni mehanizem je mehansko povezan s programatorjem, ki je v ta namen zasnovan s posebno kuliso.In special cases, e.g. in the area where the water supply is interrupted, the washing machine is designed to be fitted with a water tank, into which the user manually pours the water which he or she brings. from a remote location. This type of washing machine draws water from the tank by means of a special pump during washing. Therefore, a suitable mechanism is designed on the dosing container which directs the washing water to a specific chamber. The said mechanism is mechanically coupled to a programmer designed for this purpose with a special backdrop.

Naloga izuma je ustvariti uvodoma omenjeni pralni stroj s prigrajenim rezervoarjem, pri katerem bi se za krmiljenje delovanja uporabilo običajni elektronski programator, s čimer bi odpadla potreba po zahtevnem mehanskem programatorju in kulisi.It is an object of the invention to create the aforementioned washing machine with a reservoir, using a conventional electronic programmer to control the operation, thus eliminating the need for a demanding mechanical programmer and scenery.

Omenjena naloga je po izumu rešena s tem, da je iz rezervoarja pralne vode speljan skupni vod v vsaj eno črpalko, ki potiska pralno vodo skozi vsaj eno dovodno cev v dozirno posodo, povezano s pralno kadjo pralnega stroja. V vsakokratni dovodni cevi je izbirama razporejen elektromagnetni ventil, pri čemer je tako vsakokratna črpalka kot tudi vsakokraten elektromagnetni ventil krmiljen s pomočjo elektronskega programatorja. Če vodovodnega omrežja ni oz. je preskrba z vodo preko vodovodnega omrežja motena, je po izumu je predvideno, da se pralno vodo dovaja v dozirno posodo pralnega stroja s pomočjo vsaj ene črpalke dovaja iz rezervoarja. Kadar pa je vodovodno omrežje ustrezno, se pralno vodo dovaja v pralni stroj preko omenjenih elektromagnetnih ventilov iz vodovodnega omrežja. Uporabnik sam na pralnem stroju ročno izbira način dovajanja pralne vode v dozirno posodo pralnega stroja s pomočjo preklopnega releja na pralnem stroju.Said object of the invention is solved by connecting a common conduit to the at least one pump from the washing water tank, which pushes the washing water through at least one supply pipe into the dosing vessel connected to the washing machine washing tub. An electromagnetic valve is arranged in each supply pipe, and both the pump and the solenoid valve are controlled by an electronic programmer. If there is no water supply network or if the supply of water through the water supply network is interrupted, it is envisaged according to the invention that the washing water is fed into the dosing tank of the washing machine by means of at least one pump from the tank. However, when the water supply network is adequate, the washing water is supplied to the washing machine via the said solenoid valves from the water supply network. The user himself manually selects the method of supplying the washing water to the dosing tank of the washing machine by means of a switch relay on the washing machine.

Nadalje je po izumu predvideno, da rezervoar pralne vode obsega dovod pralne vode in v območju pod njim preliv, skozi katerega odteče prekomerna količina vode. Omenjenemu dovodu pralne vode je pri tem v notranjosti rezervoarja prigrajen na osnovi plovca zasnovan zapiralni sistem. Za povezavo z omenjenim skupnim vodom je v območju dna rezervoarja in v steni le-tega zasnovana odprtina. Omenjeni skupni vod na strani, ki skozi omenjeno odprtino sega v rezervoar, obsega prirobnico, katero pritisne z notranje strani rezervoarja v vod vstavljeni filter k steni rezervoarja. Omenjeni filter je zasnovan s cevastim nastavkom, ki je na svojem proč od širšega dela filtra obrnjenem koncu zasnovan z radialno izboklino. Omenjeni nastavek na strani prirobnice sega v omenjeni skupni vod in nanj izvaja radialni pritisk, s čimer se prepreči morebitno puščanje vode iz rezervoarja.It is further contemplated according to the invention that the wash water tank comprises an inlet of wash water and an overflow in the area below which an excess amount of water flows. In addition, a closure system is mounted on the base of the float on the inside of the reservoir for washing water supply. For connection to said common line, an opening is designed in the area of the bottom of the tank and in the wall thereof. Said common conduit on the side extending into said reservoir through said opening comprises a flange which is pressed from the inside of the reservoir by a filter inserted into the conduit into the conduit wall. Said filter is designed with a tubular attachment which is radially projected at its end away from the wider part of the filter towards the facing end. Said nozzle on the flange side extends into said common conduit and exerts radial pressure on it, thereby preventing any leakage of water from the reservoir.
