Abstract
The drum shell (20) has flow perforations (22) in the rear zone thereof, for exchange of the washing liquor (13) between the interior of the washing drum and the interior of a liquor tank (4), enclosing the above and, in the operating position for the washing machine, the lower shell line increasingly differs from a horizontal, on rising towards the front. Hollow, long lifting bodies (12), which are embodied to take liquid amounts from the deepest position thereof and raise the same, on rotation of the washing drum (5), to a raised position within the washing drum and to release the same from said raised position into the interior of the washing drum, inadequately wet the pieces of washing in the front region. The above effect is increased with reduced amounts of laundry items. According to the invention, the amount of water discharged in the interior can more effectively be applied to the laundry items, whereby the drum shell (20) has a total surface of flow perforations (23, 24), in the front region (19) thereof which measures about a quarter to a third of the total depth of the washing drum, reduced by at least 50 % relative to the rear region (21) thereof.
Description
The present invention relates to can be from the washing machine of loading previously with a rotating cleaning-drum, the cylinder shell of this cleaning-drum is provided with some and is used at the inner chamber of this cleaning-drum and surrounds the liquid flow hole of exchange wash solution between the inner chamber of lye container of this cleaning-drum and the minimum bus of this cleaning-drum extends upwardly the site of an exhibition forward in the operating position of washing machine and departs from horizontal line, this cylinder shell also is provided with the carrier of hollow microscler extension, these carrier are designed like this, make these carrier receive amount of liquid from their minimum position and this amount of liquid are raised and this amount of liquid is discharged to the inner chamber of this cleaning-drum from a position of raising when this cleaning-drum rotates.
In washing machine, for a long time, with cleaning solution washings wetting to be washed and to make this washings to be washed mechanically move to isolate foul be prior art.In tumbling-box washing machine, this function essentially horizontally is arranged on the cleaning-drum that being used in the lye container receive washings by one and bears, and this cleaning-drum rotates and washings is moved in the inner chamber of this cleaning-drum.In order to support this function, more known for a long time carrier microscler extensions, channel form is set on the cleaning-drum shell in inside, these carrier are laterally directed with respect to the direction of motion of cleaning-drum shell.This internal fixation on the cleaning-drum to carry groove known and almost be used to make in the tumbling-box washing machine washings motion for a long time without any exception from 1879 by DE-PS 8 347.
Also known in addition more such tumbling-box washing machines, carrier is settled obliquely and is extended along screw line basically on the cleaning-drum shell in inside in these tumbling-box washing machines.The tiltably-mounted of carrier under any circumstance all is in order to realize at this: the motion that the influences washings introducing of mechanical energy in the washings in other words.This tumbling-box washing machine is for example known by DE-PS 537 758, DE-PS 576 523, FR 1 136 981 and DE 44 12 718 A1.Known in addition more such tumbling-box washing machines, the tiltably-mounted by carrier in these tumbling-box washing machines reach when cylinder rotates at the cylinder inner shaft to transmitting washings.In by DE-GM 88 04 246 known tumbling-box washing machines, support the taking-up of washings in this way.
Known in addition washing machine (DE 199 25 917A1) according to claim 1 preamble, carrier is drawn water in the lowermost extent of lye container in this washing machine, raise water when rotating with convenient cleaning-drum and make water from a position that exceeds by on the unrestrained washings below being positioned at it of some mouthfuls.These carrier are fed forward the cleaning solution that is received in the case, there, the amount of liquid that is drawn can not touch the small lot washings, and rule of thumb the small lot washings is sent under the situation of the bus tiltably-mounted of bottom in the rear region and (deviates from and load mouth).Thus, the wet processes of small lot washings is delayed and is become to no effect, because the amount of liquid of being discharged liquid flow hole by cylinder shell before it can arrive washings leaks.
Task of the present invention is, improves the especially wettability of small lot washings in above-mentioned washing machine.
This task solves like this according to the present invention, and promptly cylinder shell has in its forefoot area and reduces at least 50% the liquid flow hole gross area than rear region, and this forefoot area is of a size of about 1/4th to about 1/3rd of cylinder total depth.This measure causes: be carried amount of liquid that device is raised and that forward from now on and trickle down on the few zone of perforate and flow to washings then on the shell inner surface.This has compared with prior art shortened wet processes and has wet the small lot washings effectively.In addition, also strengthened the cleaning solution exchange for whole washing process thus.
Because so the most washings of the hole face at rear portion covers and has only the anterior hole face and the inner chamber of the lye container of periphery to carry out air exchange when centrifugal dehydration, so the measure of the present invention also so-called radial pump effect of the feasible cleaning-drum that rotates reduces, air is aspirated out from lye container and is pushed back in the lye container by the liquid flow hole that is not capped again from the filling mouth that is arranged on the front in this radial pump effect.This effect causes: the centrifugal cleaning solution that throws away is taken out of from the zone of loading mouth sealing ring and with the wetting again washings of undesirable mode.
The effect of measure of the present invention preferably can reach like this, and promptly forefoot area does not have liquid flow hole.
Measure-alike with the liquid flow hole in the rear region but when comparing liquid flow hole in decreased number or the forefoot area with the liquid flow hole in this rear region and having littler internal diameter when the liquid flow hole in the favourable configuration forefoot area according to the present invention than the liquid flow hole in the rear region, wettingly equally also quickened significantly.When the cleaning solution liquid level in lye container was higher, for example when the rinsing washings, the liquid flow hole in the forefoot area also can be favourable, even these liquid flow holes seldom.
In an embodiment that liquid flow hole is not set in forefoot area, particularly advantageous can be that the forefoot area of atresia is provided with the press portion of some channel form.These press portion should be settled in one direction in the case, and this direction is supported the derivation of the centrifugal water that throws away.This situation is especially such, and promptly according to a favourable configuration of the present invention, the press portion of these channel form is aimed at the liquid flow hole spacing in the rear region and stopped before rear region.
Describe the present invention in detail by the embodiment shown in the accompanying drawing below.Accompanying drawing is represented:
Fig. 1 is according to the side view of the vibrating device of washing machine of the present invention, and this washing machine is made up of lye container and the cleaning-drum that has a carrier,
The extension of a coverboard section of first scheme of a cleaning-drum that designs according to the present invention of Fig. 2,
Fig. 3 is according to a view of the alternative plan of Fig. 2,
Fig. 4 reaches according to a view of third party's case of Fig. 2
Fig. 5 is according to a view of the cubic case of Fig. 2.
Only schematically show out vibrating device 1 and be connected the corrugated flexible hose 2 and washing liquid pump 3 of below by the washing machine shown in Fig. 1.
This device 1 that hangs quiveringly in a not shown manner is made up of the cleaning-drum 5 that lye container 4 is bearing in this lye container with reaching approximate at least concentric basically.This vibrating device 1 hangs so obliquely or is installed in the unshowned washing machine shell, promptly the pivot center 6 of cleaning-drum 5 towards the filling mouth 7 of the front side of lye container 4 with one for example 15 ° angle stretch upwards.This filling mouth is beneficial to operatively and swings towards the user thus.
Cleaning-drum is bearing in common mode with a stable axle journal 10 in the sleeve 8 on the base portion 9 of behind of lye container 4.This cleaning-drum is columned; Therefore the bus 11 of the bottom of this cleaning-drum 5 stretches upwards forward with the angle identical with the pivot center 6 of cleaning-drum.On the inner surface of roller tube, be fixed with three carrier 12 evenly distributedly.These carrier are used in common mode washings being raised during cleaning-drum 5 rotates on the one hand, this washings is by mechanical treatment like this, and promptly washings falls back to again the cylinder bottom and in the case after very high from one or not too high height are raised foul is discharged together with the cleaning solution of wetting washings.
But these carrier 12 are used for draw liquid in addition, and this liquid is in the part of the back lower place of lye container 4 as a part that is arranged in whole liquid of lye container inside, the solution 13 that promptly exposes during washing process.When relevant carrier is positioned on the minimum point of its circular trace, take out partially liq by liquid inlet 14 from this solution that exposes by this carrier 12.The opposite rotation direction with respect to cleaning-drum 5 in installation site, right angle common under carrier 12 and other situation is installed obliquely.These carrier are also crooked on cylinder rotation direction convex-shaped ground in addition.Therefore the liquid that is drawn of the inside of carrier 12 is moving upward during cylinder rotates and to forward in carrier inside with the carrier curvature identical degree of slowly overturning forward when rotating.
These carrier 12 especially have some mouthfuls 16 in forefoot area on their sidewall 15 of convex ground arching, be used to discharge the amount of liquid that is drawn.In recessed sidewall 17, these carrier do not have or only have considerably less such mouth and these mouths also only forwardly and very near top seamed edge 18.Therefore realized: the very big part of the amount of liquid that is drawn is watered and is being positioned on the washings part of front.But owing to the obliquity of pivot center 6, the considerable part of the amount of liquid that is drawn also offers very by afterwards being arranged in the washings part of cylinder 5 simultaneously.
Do not express among Fig. 1: the shell of cleaning-drum 5 is run through in this wise by liquid flow hole, makes the cleaning solution that can continue between the inner chamber of the cleaning-drum that rotates and the solution 13 that exposes exchange.This good cleaning action for washings has very big meaning.Promptly try hard to all the time reach: the unit interval, cleaning solution as much as possible flow through washings.But when according to starting described washing machine liquid flow hole being set equally in the forefoot area of cylinder shell now as common in the prior art, then too much passing through drawn carrier and trickled down cleaning solution on washings and do not have wetting washings just to be directed into these liquid flow holes immediately and leave from cylinder more there.Certainly, the washings in cylinder is fewer, and this effect is stronger; Because if top liquid flow hole exposes owing to the washings amount is little, the water yield under then trickling down is very most of to be spilt by these liquid flow holes, and does not contact with washings at all.
For fear of this shortcoming, the cleaning-drum of washing machine constructed according to the invention does not have or only has the liquid flow hole that quantity reduces or size reduces in forefoot area, make thus unrestrained down but not yet the amount of liquor that absorbs of washings enough be retained in for a long time on the base portion of forefoot area of cleaning-drum, be capped its washings absorption up to this amount of liquor.
In an embodiment according to Fig. 2 of the present invention, in the forefoot area 19 of cylinder shell 20,, liquid flow hole is not set with different in rear region 21, in this rear region, be provided with liquid flow hole 22 in a conventional manner.This face is a porous not fully, but the cleaning solution maximum duration ground that impacts from the top thus on this face keeps supplying moistened garment.
But obstruction is arranged because water or cleaning solution are crossed long-time the stop on the base portion of cleaning-drum, for example for when the cleaning solution liquid level is high, flowing through washings consumingly or draining during for centrifugal dehydration has obstruction, so advantageously, according to a further configuration of the present invention, all gross areas that are arranged on the liquid flow hole in the forefoot area reduce in all the other zones relatively.This can embody by liquid flow hole 24 identical most amounts, that cross section reduces by reducing at the number of the measure-alike liquid flow hole of others or according to Fig. 4 according to Fig. 3.The mixed form that this external same inventive concept can be considered any kind down wherein also can use the liquid flow hole with multiple different-diameter or cross section.
For example important when centrifugal dehydration may be that the centrifugal water that throws away leaves from cleaning-drum as far as possible apace.This can support like this according to Fig. 5, and the depressed part 25 of channel form promptly is set in this forefoot area 19, and these depressed parts point to towards the zone 21 that is equipped with common liquid flow hole 22.On the centrifugal dehydration direction these grooves helically in one direction or on another direction or on both direction is spiraled in the case.In order to derive the water of collecting in this way immediately, advantageously, these grooves lead to top liquid flow hole in the zone 21 of common liquid flow hole.
