Description
Oblasť technikyTechnical field
Vynález sa týka automatickej práčky so skriňou typu, uvedeného vo všeobecnom pojme patentového nároku 1 .The invention relates to an automatic washing machine with a cabinet of the type mentioned in the general concept of claim 1.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Moderné automatické práčky vyššej triedy vyžadujú v chode orania, tak aj v chode odstreďovania odlišné frekvencie otáčania bubna práčky. Pritom majú hodnoty frekvencie otáčania pri odstreďovaní dosahovať 130C až 2000 zá minútu, zatiaí čo sa usiluje o hladinu zvuku nanajvýš pre pranie LWA 47 dB a ore odstreďovanie LWA 49 dB.Modern high-end automatic washing machines require different rotational speeds of the washing machine drum in both plowing and spinning operations. At the same time, the spin speed values at spinning should be 130C to 2000 ppm, while trying to achieve a sound level of at most LWA washing of 47 dB and or spinning LWA of 49 dB.
Doterajšie automatické- oračky pracujú) s DC-motorom s ?Wchooperom a bubnom, hnaným remeňom, pričom najvyššie frekvencie otáčania pri odstreďovaní sú približne 1400 za minútu.The current automatic tillage machines operate with a DC motor with a? Wchooper and a belt driven drum, with the highest spinning speeds of approximately 1400 per minute.
Hore uvedené, usilované hodnoty hladiny zvuku sa nedajú pri tomto známom automate dosiahnuť.The above-mentioned desired sound level values cannot be achieved with this known automatic machine.
Aby sa dosiahli želané hodnoty, čo sa týka frekvencie otáčania odstredivky a nízkej hladiny zvuku, nemôže sa U-mo tor v DC-preváčzke, najmä z dôvodov frekvencie otáčania používať, pretože U-motor sa nemôže pohýnať od svojej frekvencie otáčania motora nad 13C0 za minútu. Okrem toho sú jednosmerné motory, prichádzajúce do úvahy, postihnuté nevýhodne vysokým opotrebovaním kefiek, silnou tvorbou hluku vo vysokých frekvenciách otáčania, ako aj ťažkosťami, vystupujúcimi v odrušovaní.In order to achieve the desired values with respect to the spin speed of the centrifuge and the low sound level, the U-motor in the DC coupler cannot be used, in particular because of the rotation speed, since the U-motor cannot move away from its motor speed above 13C0. minute. In addition, the DC motors in question are affected by disadvantageously high brush wear, high noise generation at high rotational speeds, as well as difficulties in interference suppression.
Podstata vynálezuSUMMARY OF THE INVENTION
Základom vynálezu je úloha, vytvoriť automatickú práčku, najmä pre vyššiu triedu, s ktorou sa dajú všetky želané frekvencie otáčania od 25 do 2000 za minútu produkovať pre odstreďovanie a pre rozličné postupy prania bez nepriaznivých následkov. Súčasne sa má docieliť prací a odstreďovací účinok, ktorý sa má rozsiahle rovnomerne udržiavať, pri Čo možno konštantných frekvenciách otáčania s nízkej hladine zvuku. Táto úloha sa rieši charakteristikami, vyznačenými v oatentovom nároku 1.The object of the invention is to provide an automatic washing machine, in particular for a higher class, with which all the desired rotational speeds from 25 to 2000 per minute can be produced for spinning and for various washing processes without adverse consequences. At the same time, a washing and spinning effect is to be achieved, which is to be largely maintained evenly, at constant rotational frequencies with a low sound level. This object is solved by the characteristics indicated in the patent claim 1.
Pretože bubon práčky je priamo vysokopolovým motorom poháňaný, môže vyhovovať požiadavke ohraničenia frekvencií otáčania, pri ktorom je maximálna frekvencia otáčania motora totožná so želanou vysokou frekvenciou otáčania odstredivky. Žiadúca nízka úroveň hladiny zvuku sa dosiahne tým, že hnací motor sa zapuzdrí tlmiacim poklopom. Prídavné môže mať potom ešte aj zadná stena kade zvukovú izoláciu. Pretože hnací motor nemá žiadne kefky a je prednostným spôsobom ako synchrónny motor s meničom vytvorený, môže sa zapuzdrenie motora naplánovať z termických dôvodov bez pochybností. Toto je uprednostňované ešte aj tým, že elektronické zariadenie nie usporiadané na motore.Since the drum of the washing machine is directly driven by the high-pole motor, it can satisfy the requirement of limiting the rotational frequencies at which the maximum rotational speed of the motor is identical to the desired high rotational speed of the centrifuge. The desired low sound level is achieved by encapsulating the drive motor with a silencing cover. In addition, the back wall can also have sound insulation. Since the drive motor has no brushes and is preferably constructed as a synchronous motor with an inverter, the motor housing can be scheduled for thermal reasons without any doubt. This is also preferred because the electronic device is not arranged on the engine.
Ďalšie výhodné rozpracovania predmetu vynálezu sa môžu prebrať z ďalších dolu uvedených nárokov.Further advantageous developments of the subject matter of the invention can be taken from the further claims below.
Vynález sa popisuje bližšie na základe príkladu, znázorneného na obrázku.The invention is described in more detail on the basis of the example shown in the figure.
Automatická práčka 1 má skriňu 3, v ktoré je umiestnená mechanicky oscilujúca jednotka zariadenia 5, ktorá pozostáva z vodorovne ležiaceho prepieracieho bubna 7, z kade 9, ktorá tento obklopuje, a z hnacieho motora 11, ktorý bubon práčky 7 priamo poháňa. Ostatné časti, nutné na riadenie automatickej práčky 1, nie sú bližšie znázornené.The washing machine 1 has a housing 3 in which a mechanically oscillating unit of the device 5 is located, which consists of a horizontal lying washing drum 7, a tub 9 surrounding it and a drive motor 11 which drives the washing machine drum 7 directly. The other parts necessary for controlling the washing machine 1 are not illustrated in detail.
Hnací motor i 1 je usporiadaný ako motor bez kefiek naThe drive motor 11 is arranged as a brushless motor on
- 3 vonkajšej strane 22 zadnej steny 1 5 kade a obklopený izolačnou kapotou 13, ktorou sa hluk motora účinne odrušuje. Pritom je izolačná kapota 13 pevne spojená so zadnou stenou 15 kade3 outside the rear wall 15 of the vat and surrounded by an insulating hood 13 which effectively suppresses the engine noise. The insulating hood 13 is rigidly connected to the rear wall 15 of the vat
9. Pretože riadiace elektronické zariadenie '6 nie je umiestnená nä'hnacom motore ' 1 , ale na mieste, od neho vzdialenom, skrini 3, napríklad v oblasti čelnej steny iS, môže sa zapuzdrenie hnacieho motora 11 bez pochybností naplánovať, najmä keč hnací motor 11 nemá žiadne kefky.9. Since the control electronic device 6 is located not in the pulling motor 1 but in a place remote from it, the housing 3, for example in the area of the front wall 15, the encapsulation of the drive motor 11 can be planned without doubt, especially the drive motor. 11 has no brushes.
Zasiahnutie želanej hladiny zvuku môže byt podporované aj tým, že vnútorná strená 17 zadnej steny kade je vybavená ešte jednou izolačnou vrstvou 19. Hnací motor 11 je motorom s vonkajším rotorom, ktorého rotor- s permanentným magnetom, vytvorený ako vonkajší rotor 23, pohana priamo hnací hriadeľ 24 bubna práčky 7· Hnací hriadeľ 24 je pritom jednostranne otáčavo uložený v ložisku, pozostávajúcom z dvoch valivých 1< zisk 26, 27, v hlave 23, vyčnievajúcej smerom von, na zadnej stene kade 15. Stator 25 so statorovým zväzkom plechov 30 je pritom usporiadaný prstencovito k hlave 23.The impact of the desired sound level can also be supported by the fact that the inner wall 17 of the back wall of the vat is provided with an additional insulating layer 19. The drive motor 11 is an external rotor motor whose permanent magnet rotor 23 is driven directly by the driving rotor 23. In this case, the drive shaft 24 is rotatably mounted on one side in a bearing consisting of two rolling elements 26, 27, in the head 23 projecting outwardly on the rear wall of the box 15. The stator 25 with the stator bundle of plates 30 is arranged in an annular manner to the head 23.
Vysokopólovým vytvorením hnacieho motora 11 pri počte pó lov >10 sa môže požiadavke ohraničenia frekvencií otáčania, pri ktorom je maximálna frekvencia otáčania motora totožná s frekvenciou otáčania odstredivky, účinne vyhovieť. Hnací motor 11 môže byť buč synchrónnym motorom...s...meničom, alebo aj reluktančným motorom. Izolačná kapota 13, ktorá obklopuje hnací motor 11, pozostáva z dutého valca 21, jednostranne uzavretého dnom 20, ktorý tesne obopína vonkajší rotor 23 a ktorého okraj otvoru 25 je pevne spojený so zadnou stenou 15 kade.The high-pole design of the drive motor 11 at a number of poles> 10 can effectively satisfy the requirement of limiting the rotational frequencies at which the maximum rotational speed of the motor is identical to that of the centrifuge. The drive motor 11 may be either a synchronous motor ... with a converter or a reluctance motor. The insulating hood 13, which surrounds the drive motor 11, consists of a hollow cylinder 21, closed on one side by a bottom 20, which tightly embraces the outer rotor 23 and whose edge of the opening 25 is fixedly connected to the rear wall 15 of the vat.
Automatická práčka 1 podľa vynálezu môže byt prevádzkovaná s frekvenciami otáčania motorového pohonu do 25 do 2000 za minútu, pričom pomocou zvukového zapuzdrenia hnacieho motora 11 sa dosahuje jednoducho a účinne aj žiadúca hladina zvuku.The washing machine 1 according to the invention can be operated with a rotational speed of the motor drive of up to 25 to 2000 per minute, and by means of the sound encapsulation of the drive motor 11, the desired sound level is achieved easily and effectively.
