Description

Sušilnik perila s filtrom sušilnega zrakaLaundry dryer with dryer air filter

Predlagani izum se nanaša na sušilnik perila, obsegajoč boben z odprtino za sprejem perila, ki naj se ga suši, vsaj deloma prozorna ali prosojna vrata, ki zapirajo omenjeno odprtino za sprejem perila, ki naj se ga suši, grelno sredstvo za segrevanje sušilnega zraka, hladilno sredstvo za izločanje vlage iz sušilnega zraka, transportno sredstvo za kroženje sušilnega zraka po sušilniku perila in filtrirno enoto za sušilni zrak, ki se ga vodi iz omenjenega bobna.The present invention relates to a laundry dryer comprising a drum with an opening for receiving laundry to be dried, at least partially transparent or transparent doors closing said opening for receiving laundry to be dried, a heating agent for heating the drying air, a refrigerant for extracting moisture from the drying air, a means of transport for circulating the drying air through the laundry dryer, and a filter unit for drying air operated from said drum.

Znan je sušilnik perila uvodoma navedene vrste, pri katerem so vrata zasnovana vsaj deloma prozorno ali prosojno, konkretno s steklom, ki omogoča vpogled v boben tudi med sušenjem. Filtriranje sušilnega zraka je predvideno s pomočjo vrečastega mrežastega filtra, razporejenega v območju odprtine za vlaganje perila, konkretno v območju pod vrati v zračnem kanalu, ki poteka pod vrati. Mrežasti filter je lahko nameščen tudi na samem vstopu v omenjeni zračni kanal oziroma v območju pod steklom. Mrežastemu filtru običajno sledi(ta) še dodatni mrežasti in/ali penasti filter pred vstopom zraka v kondenzator oz. v uparjalnik, če sušilnik perila obsega toplotno črpalko. Tovrstna izvedba je potrebna predvsem zaradi finih delcev, ki jih običajni mrežasti filter pod steklom vrat v celoti ne zadrži in bi se nabirali na površinah toplotnih izmenjevalcev.The laundry dryer of the aforementioned type is known, in which the door is designed at least partially transparent or translucent, in particular with glass, which provides insight into the drum even during drying. Drying air filtration is envisaged by means of a bag-shaped filter arranged in the area of the linen opening, specifically in the area under the door in the air duct under the door. The mesh filter may also be installed at the very inlet of said air duct or in the area under the glass. The mesh filter is usually followed by (this) an additional mesh and / or foam filter before the air enters the condenser or. into the evaporator if the laundry dryer comprises a heat pump. This type of construction is particularly necessary because of the fine particles which are not completely retained by the ordinary mesh filter under the door glass and would accumulate on the surfaces of the heat exchangers.

Pomanjkljivost obstoječih rešitev je, da postavitev vrečastega filtra v območju spodnjega dela odprtine za vlaganje perila zmanjšuje pretok skozi zračni kanal. Vrečasto zasnovanThe disadvantage of the existing solutions is that the placement of a bag filter in the area of the lower part of the laundry inlet reduces the flow through the air duct. Baggy designed

P2150213-156/bi filter je običajno potrebno razkleniti, odpeti zaskoke, kar lahko predstavlja neprijazno rokovanje. V nekaterih primerih je vrečasti filter celo dvojne izvedbe, to je filter v filtru. V takem primeru je potrebno razstaviti dva elementa, da lahko filter očistimo, operemo in ga očiščenega zopet vrnemo v ležišče. Ker je to po navodilih proizvajalcev potrebno storiti po vsakem sušenju, pride posledično do obrabe zaskočnih sredstev in celo loma mrežastega filtra, kar se pogosto dogaja zaradi staranja materiala.P2150213-156 / bi filter usually needs to be unbuttoned, latching open, which can be an unpleasant handling. In some cases, the bag filter is even of double design; In this case, it is necessary to disassemble two elements so that the filter can be cleaned, washed and returned to the bed again. Because, according to the manufacturer's instructions, this must be done after each drying, there is a risk of wear and tear on the locking means and even breaking of the strainer, which is often due to aging of the material.

Vrečasti filter mora biti zasnovan tako, da se njegova vstopna odprtina nahaja v območju pod steklom vrat. Zaradi tega je odprtina za vstavljanje perila v boben zmanjšana, kar predstavlja za uporabnika manj prijazno rešitev. Dalje je omenjeni mrežasti filter običajno razporejen v spodnjem delu odprtine za vlaganje perila, zaradi česar je posledično zmanjšana velikost same odprtine za vlaganje perila.The bag filter must be designed so that its inlet is located in the area below the door glass. As a result, the opening for inserting laundry into the drum is reduced, making it a less user-friendly solution. Further, said mesh filter is typically arranged in the lower part of the linen opening, which results in a reduced size of the linen opening itself.

Naloga predloženega izuma je ustvariti sušilnik perila s filtrom sušilnega zraka, s katerim je pri vsaj deloma prozornih ali prosojnih vratih sušilnika zagotovljeno ustrezno filtriranje zraka, sočasno pa se ne zmanjša odprtine za vlaganje perila.It is an object of the present invention to provide a laundry dryer with a drying air filter, which ensures at least partially transparent or translucent dryer doors to provide adequate air filtration, while not reducing the load opening of the laundry.

Po predlaganem izumu je predvidena izvedba vsaj deloma prozornih ali prosojnih vrat sušilnika perila, na primer s steklom, in filtrimo enoto, ki se nahaja v sklopu vrat v ustrezni vboklini v steklu. S tem se doseže, da je zgornji del filtrirne enote, to je filtrirni vložek s pokrovom, viden tudi pri zaprtih vratih sušilnika. Po izumu je predvideno, da je omenjeni pokrov filtrirnega vložka zasnovan kot estetski element, na katerega se da aplicirati grafične dodatke, ki so vidni skozi steklo. Omenjeni grafični dodatki so npr. marketinški napisi, navodila za uporabo ipd. Dalje je omenjeni pokrov filtrirnega vložka vsaj deloma opremljen s premazom ali vsaj deloma izdelan iz materiala, ki spremeni svojo barvo v odvisnosti od temperature in/ali vlažnosti sušilnega zraka. S tem je tekom sušenja omogočeno, da se uporabniku posreduje informacije, na primer o temperaturi sušilnega zraka, preostali vlagi v zraku, preostalem času sušenja ipd.According to the present invention, it is envisaged that at least partially transparent or translucent doors of the laundry dryer, for example with glass, be constructed and a filter unit located within the door assembly in a suitable recess in the glass is filtered. This ensures that the upper part of the filter unit, that is, the filter cartridge with the lid, is also visible when the dryer door is closed. According to the invention, said filter cartridge cover is designed as an aesthetic element to which graphical accessories visible through the glass can be applied. These graphical accessories are, for example. marketing inscriptions, instructions for use, etc. Further, said filter cartridge lid is at least partially coated or at least partly made of a material that changes color depending on the temperature and / or humidity of the drying air. This allows drying to provide the user with information such as drying air temperature, residual moisture in the air, remaining drying time, and the like.

Nadalje je po predlaganem izumu predvideno, da lahko omenjeni pokrov filtrirnega vložka služi kot ročaj za odpiranje filtrirne enote. Filtrirni vložek se po izumu torej odstrani z enim samim potegom, s katerim se sočasno odpre filtrirno enoto in filtrirni vložek izvleče iz ležišča. Ohišje filtrirne enote je lahko sestavljeno iz dveh ali več delov, npr. iz ohišja in stene s perforacijo. S tem je omogočeno prilagajanje vzorca perforacije različnimFurther, it is contemplated by the present invention that said filter cartridge cover can serve as a handle for opening the filter unit. The filter cartridge according to the invention is therefore removed by a single pull, which simultaneously opens the filter unit and removes the filter cartridge from the bed. The filter unit housing may consist of two or more parts, e.g. from housing and wall with perforation. This allows the perforation pattern to be adjusted to different ones
