A water and/or detergent charging apparatus for automatically controlled drum-type washer has a charge tube aimed at the peripheral surface of washing drum. Hollow washing drive lever has water-suction holes and water-discharging holes on its external surface. In order to have shorter washing time, better cleaning effect and less consumption of detergent, when drum locating unit stops the washing drum, its inlet of input tube stops opposite to washing drive lever as correctly as possible and said input tube is always opened effectively, so directly spraying water and/or detergent onto clothes in drum via drive lever.

Description

Automatically the tumbling-box washing machine of control adds water and/or adds the device of washing agent

The present invention relates to a kind of the adding water and/or add the device of washing agent of tumbling-box washing machine of automatic control, the input pipe that leads to washing liquid tank from the washing agent adding apparatus is aimed on the circumferential surface approach the cleaning-drum of rotatable support washing liquid tank flatly at least, cleaning-drum has three washing driving levers at least, and washing driving lever the inside is empty and shell side is furnished with the suction hole and is discharged to osculum in the cleaning-drum.Simultaneously, this device effectively is connected with a cleaning-drum positioner, can be parked in cleaning-drum on the precalculated position by this positioner.

DE-OS 40 37 868 has proposed this washing machine.Wherein a kind of localization method and a kind of device of implementing this method have been narrated by means of a kind of tumbling-box washing machine of casing side loading.Though above-mentioned publication is not narrated detergent-adding device, this detergent-adding device belongs to common prior art, so can directly therefrom draw such conclusion: the washing machine that above-mentioned publication is addressed has this detergent-adding device certainly; This is equally applicable to above-mentioned washing driving lever.This washing driving lever has such structure, when it when being positioned at the cleaning solution of washing liquid tank bottom, take away the part cleaning solution, and enter in the drum cavity by osculum in higher position.

This known detergent-adding device is added to clear water and washing agent on the cleaning-drum from below adding washing liquid tank or from side or from the top from pouring Pan Chu.But have only on the clothing that seldom a part of water and washing agent will wash by the direct arrival of the leaking hole of cleaning-drum.Most of water and washing agent at first flow into the bottom of washing liquid tank, and temporarily still undissolved a part of washing agent is being deposited at the end of washing liquid tank, and is only just mixing, dissolving and be evenly distributed on the clothing with water gradually by rotatablely moving of cleaning-drum.Consequently, delayed the chemical action of washing agent to clothing.

Task of the present invention is the water and the washing agent of input cleaning-drum are directly delivered on the clothing that will wash in the cleaning-drum, makes clothing very fast drenched and washing agent is directly delivered on the clothing as early as possible.

This task of the present invention is to be finished by an above-mentioned device, the feature of this device is: when the inlet that cleaning-drum is parked in the washing liquid tank input pipe when the cleaning-drum positioner was positioned at the position, opposite of a washing driving lever as far as possible exactly, this device that input pipe adds water and/or add washing agent that passes through by washing machine control was just connected.

Like this, feeding water that in washing machine, circulates from the clear water of running water pipe or by circulating line and washing agent just can be directly from the inlet of input pipe on the clothing that the orifice flow of driving lever will be washed to the cleaning-drum.Like this, clothing is drenched rapidly and produce chemical action rapidly with washing agent, thereby has realized short wash time, clean result and less washing agent consumption preferably.

Concerning the washing machine of casing side loading, apparatus of the present invention structurally have special advantage, be that the stop position of cleaning-drum just in time makes the charging hole of cleaning-drum be positioned at the opposite of the perpendicular letter of dress clothing of washing machine shell, that is these design features of washing machine can be implemented in input pipe inlet below and have at least a driving lever to be parked on the stop position.

In one of apparatus of the present invention favourable improvement structure, the width that the inlet of input pipe is measured in the cylinder direction of rotation is less than the suction hole of driving lever, thereby such advantage is arranged: the peak demand that site error needn't be satisfied in the location of cleaning-drum just can be set up suitable corresponding relation between the suction hole of the inlet of input pipe and the driving lever that stops.

Apparatus of the present invention also can structurally be done such improvement, and promptly cylinder can be parked in any driving lever and input pipe and enters the mouth on the corresponding position.The advantage of this structure is that when adding clear water again and/or adding washing agent, cylinder need not rotate a whole circle and stir clothing.When rotating whole a circle, same probably clothing part is translated on the top original position again.That is cleaning-drum the next position of forwarding three driving levers to only rotates three/can realize piling up fully again of clothing once enclosing, thus other clothing part just be positioned at location last time above.Consequently, clothing soak into carry out more thoroughly, more all even rapider and washing agent is added on whole clothings.

Certainly apparatus of the present invention also are applicable to the washing machine that the front is reinforced.Describe the present invention in detail below in conjunction with the accompanying drawing illustrated embodiment.Accompanying drawing is:

The part schematic side view of washing machine when Fig. 1 represents that cleaning-drum is in the position location;

Fig. 2 represents a washing driving lever cutting open along circumference profile.

From the clear water (by a solenoid control that does not illustrate among the figure) of the pipeline that does not draw among the figure or flow into washing agent from the recirculated water (by the circulating pump control that does not illustrate among the figure) of the circulating line that does not illustrate among the figure and pour in the dish 1, be placed on and pour water that the washing agent in the dish 1 flowed into flows into cleaning-drums 4 by the inlet 8 of corrugated flexible hose 2 and washing liquid tank 3 shell side outer surface.Three washing driving levers 5 are arranged in the inboard on cleaning-drum surface, washing driving lever 5 then has suction hole 6 in shell side, and the suction hole enters (being so-called water absorption type driving lever) the cleaning-drum to water from the suction of washing liquid tank bottom and from higher position by osculum 7 in washing process.

Suppose that the diagram washing machine has an above-mentioned cleaning-drum positioner.The parts that belong to this device are not intended giving unnecessary details here.The inlet 8 of input pipe 2 is to be arranged in like this on the shell of washing liquid tank 3: when cylinder 4 forwards so-called stop position to by pull back device, the lid of the cleaning-drum that shell side can be feeded just in time is parked in the below of dress clothing column 9, and 8 opposites that just in time are positioned at the suction hole 6 of driving lever 5 at this moment enter the mouth.Like this, the water of inflow and/or washing agent just can directly be fallen on the clothing that will wash in the cleaning-drum 4 by input pipe 2 with inlet 8 corresponding driving levers 5.

Have on the position of a driving lever 5 if all be transferred to inlet 8 opposites before the each water inlet of cleaning-drum, then the overwhelming majority of water that will flow into and/or washing agent all flows directly on the clothing in the cleaning-drum inner chamber.Because must there be error this location of cleaning-drum, thereby may produce the site error of the inlet 8 of the 6 pairs of washing liquid tanks 3 in suction hole in the driving lever 5.8 clear distances that get along the outline side vector are less than the clear distance in suction hole 6 if enter the mouth, and then this error is harmless.Like this, under any circumstance entering the mouth 8 all can be corresponding with suction hole 6, and water and/or washing agent can directly be delivered on the clothing that will wash.
