Description

The present invention relates to a detergent dispensing device of a washing machine.

It also relates to a washing machine comprising a detergent dispensing device, and in particular a washing machine or a dishwashing machine.

It applies more particularly to the distribution of detergent in the form of powder, liquid or semi-liquid (gel type) in the field of domestic washing machines.

It also applies to the distribution of one or more products in the prewash, wash and / or rinse phases used in domestic washing machines.

The present invention relates to the automatic dispensing of detergent, which may be one or more detergents and / or one or more additives, in a washing tub of a washing machine or dishes.

We already know the document EP 1 593 766 A1 which describes a compartment of a dispenser for dispensing detergents for a washing machine, equipped with a rotary mechanism for dispensing each detergent. Rotation occurs by the weight of water supplied and accumulated in a counterweight receptacle connected to the compartment, regardless of the flow rate of the washing machine supply valve.

This compartment includes a pocket for the accumulation of a washing product and a pocket for the accumulation of the counterweight water. These two pockets are separated by a common partition. The position of the center of gravity of the compartment relative to the axis of rotation of said compartment makes it possible to maintain the compartment in equilibrium so that the washing product introduced into the accumulation pocket of a detergent can not tilt the compartment in emptying position. On the contrary, the presence of detergent in the accumulation pocket of a compartment detergent reinforces this state.

The water filling in the counterbalance water accumulation pocket of the compartment is counterbalanced with respect to the accumulation pocket of a washing product so as to tilt the compartment into the emptying position by changing the position of its center of gravity.

However, this compartment of a dispenser for dispensing detergents for a washing machine has the disadvantage of providing a bag of accumulation of a detergent in the compartment of large volume.

Therefore, the size of such a compartment is bulky.

In addition, when rotating the compartment, the counterweight water contained in the counterbalance water accumulation bag empties instantly and can no longer produce the counterweight effect.

Therefore, lack of the presence of the counterweight water in the counterweight water accumulation pocket, the compartment returns to the initial position. If the duration of emptying the detergent accumulation bag is not long enough to allow a complete emptying thereof, the compartment returns to its initial position while containing a portion of the detergent in the bag of detergent. accumulation of detergent.

On the other hand, in the case where the washing product is powder, the powder can become waterlogged at least in part and becomes heavier.

Therefore, the compartment may not turn over again if the counterweight water in the counterweight water accumulation pocket does not exert a sufficient torque relative to the mass of detergent in the accumulation bag of washing product.

Furthermore, in the case where the detergent adheres to the walls of the detergent accumulation bag and can not flow during the rotation of the compartment in the emptying position, the compartment returns to its initial position while containing part of the detergent in the detergent accumulation bag.

The document is also known US 2,990,707A which discloses a detergent delivery device of a washing machine comprising at least one detergent container that can hold a quantity of detergent, at least one receptacle that can hold a quantity of water, wherein the at least one detergent container is driven in rotation following the water filling of said at least one receptacle.

The rotational drive of said at least one detergent tank 7 is caused by the spring 14 connected on the one hand to said at least one float 18 and on the other hand to the driving element 12, following the displacement of said at least one a float 18 by the water level reached in said at least one receptacle 8 and the unlocking of the driving element 12.

The traction of the spring 14 makes it possible to rotate said at least one detergent container 7 from a position armed with the at least one trigger device 9 to a disarmed position of the at least one trigger device 9.

As soon as the driving element 12 is released with respect to said at least one float 18, said at least one detergent tank 7 is rotated about its axis of rotation 13 by the spring 14.

Here, the axis of rotation 13 is common to said at least one detergent container 7 and to the drive element 12. Said at least one detergent container 7 and the drive element 12 are integral so as to be rotated together about the axis of rotation 13 by the spring 14.

In the case where an interruption of the water supply of said at least one receptacle 8 occurs following the triggering of the driving element 12 coupled to said at least one detergent tank 7, said at least one detergent tank 7 is driven. in rotation to a disarmed position of said at least one trigger device 9 by the spring 14 without being able to return said at least one detergent tank 7 to the initial position by the amount of water accumulated in said at least one receptacle 8.

Advantageously, the spring 14 is fixed on the axis of rotation 11 of said at least one float 18.

Thus, the spring 14 makes it possible to rotate said at least one detergent tank 7 about its axis of rotation 13 from a position armed with said at least one triggering device 9 to a disarmed position of said at least one triggering device 9.

The spring 14 can also make it possible to push the at least one float 18 towards the bottom wall 10a of the at least one receptacle 8.

Here, the spring 14 is a spring blade.

Of course, the type of spring is in no way limiting and may be different.

In the embodiment illustrated in Figures 4 to 6 the spring 14 is also supported on a stud 20 of the driving element 12 so as to drive the driving element 12 in rotation.

Preferably, the driving element 12 is set in motion following the exceeding of the point of equilibrium between the tensile force of the spring 14, where the spring 14 exerts a torque with respect to the axis of rotation 11 of the at least one float 18, and the force exerted by the water level reached in said at least one receptacle 8 on said at least one float 18 while taking into account the friction of contact between said at least one float 18 and said drive member 12 due to the pulling of the spring 14 on said driving element 12.

Advantageously, said at least one float 18 comprises a notch 15 so as to retain the driving element 12 in the filling position of said at least one detergent container 7, as illustrated in FIG. figure 5a .

Here, the notch 15 is formed in an arm 18a of the float 18 connecting the axis of rotation 11 to the buoyancy body 18b.

In a detergent dispensing device 6 as illustrated in FIGS. Figures 1 to 8 , the torque exerted by the thrust of the water level on said at least one float 18 must be greater than that exerted by the spring 14 connected to the driving element 12 added to the friction forces of the driving element 12 on said at least one float 18 while taking into account the torque that can be exerted by said at least one float 18.

In one embodiment, said at least one triggering device 9 comprises a lever 16 cooperating with said at least one float 18 so as to release said at least one detergent container 7 from a position armed with said at least one trigger device 9 to a disarmed position of said at least one trigger device 9.

Here, the lever 16 is supported on an arm 18a of the float 18 connecting the axis of rotation 11 to the buoyancy body 18b.

Thus, said at least one detergent container 7 can be rotated from a closed position of a detergent filling and emptying opening 21 of said at least one detergent container 7 to a release position of the opening filling and emptying detergent 21 of said at least one detergent tank 7 by means of a lever 16 while driving said at least one trigger device 9 from an armed position to a disarmed position.

The disarming of said at least one trigger device 9 by means of the lever 16 makes it possible to rotate said at least one detergent container 7 from a closed position of a filling and emptying aperture 21 of said at least one detergent tank 7 to a position of disengagement of the filling opening and emptying of detergent 21 without having to directly touch said at least one detergent container 7 can be covered with traces of detergent, as shown in FIGS. Figures 6a to 6e .

This disarming of said at least one triggering device 9 can be realized by pressing a portion of the lever 16 protruding from the hubcap 10 so as to be accessible by the user.

This portion of the lever 16 protruding from the hubcap 10 can thus constitute a button for initializing said at least one detergent tank 7 in filling and emptying position of detergent.

This portion of the lever 16 may either protrude from the front wall of the trim 10 or from a side wall of the trim 10.

The portion of the lever 16 protruding from the trim 10 may have either a translation movement or a rotational movement relative to the trim 10.

The lever 16 can thus allow the user to move the at least one detergent container 7 from a closed position of a filling and emptying opening 21 of the detergent of said at least one detergent tank 7 to a position of clearance of filling and emptying opening with detergent 21.

Advantageously, the lever 16 comprises a first arm that can bear on said at least one float 18 and a second arm that can bear on the drive element 12, where the first and second arms of the lever 16 are interconnected.

Here and in no way limiting, the lever 16 has a U-shape for interconnecting the first and second arms thereof.

Following a support on the lever 16 by the user, the lever 16 makes it possible to push the said at least one float 18 so as to cause the disengagement of the driving element 12 from the notch 15 formed in the said at least one float 18.

In a non-illustrated embodiment, the lever 16 can be connected to an additional spring to allow said at least one float 18 to be pushed back.

Then, the lever 16 is pushed by the force of the spring 14 exerted on the drive element 12 so as to allow the rotation of said at least one detergent container 7 from a closed position of an opening filling and emptying detergent 21 of said at least one detergent tank 7 by the hubcap 10 at a position for disengaging the filling and emptying opening with detergent 21 relative to the hubcap 10.

Then, said at least one detergent tank 7 is in the position of filling and emptying detergent as soon as the driving element 12 no longer bears on the lever 16 by rotation of the driving element 12 around the rotation axis 13 caused by the spring 14.

In one embodiment, as illustrated in Figures 6a to 6e , the lever 16 is guided in translation relative to the hubcap 10.

Here and in no way limiting, the guide of the lever 16 is formed by ribs 22.

We will now describe, in particular with reference to Figures 6a to 6e and 5a to 5d , a method of operation of a detergent dispensing device according to the invention.

The method of operation of the detergent delivery device 6 comprises a detergent filling step of the at least one detergent container 7.

The detergent filling position of said at least one detergent tank 7 is the initial position of the latter where said at least one trigger device 9 is disarmed, that is to say the position taken by said at least one detergent tank 7 following the displacement of said at least one float 18 as soon as a water level threshold value is exceeded in said at least one receptacle 8 triggering said at least one triggering device 9, or following a support on the lever 16.

In the case where the detergent dispensing device 6 comprises a plurality of detergent tanks 7 and the user does not wish to use at least one detergent tank 7, said detergent tank 7 can be left in the initial position of The position of the float 18 associated with the detergent tank 7 that is not used can be modified following the filling and the accumulation of water in the respective receptacle 8 without causing any consequences. on the other elements of the detergent dispensing device 6.

The operating method of the detergent dispensing device 6 may optionally comprise, previously, a step of initializing said at least one detergent container 7 in the position of filling and emptying detergent.

Said at least one detergent container 7 is initialized in the filling and emptying detergent position by rotating said at least one detergent container 7 so as to disarm said at least one trigger device 9.

Disarming said at least one trigger device 9 is achieved by rotating the drive member 12 about the axis of rotation 13 to the filling and emptying position of the detergent of said at least one detergent container 7 .

In one embodiment, said at least one detergent container 7 is rotated from a closed position of a detergent filling and emptying opening 21 of said at least one detergent container 7 to a disengaging position of the filling and emptying opening of detergent 21 by means of a lever 16 while driving said at least one trigger device 9 from a disarmed position to an armed position.

The rotational drive of the driving element 12 around the axis of rotation 13 is implemented by pushing the lever 16 against the at least one float 18 until the driving element 12 disengaging a notch 15 of said at least one float 18.

The notch 15 of said at least one float 18 and the driving element 12 respectively have slopes on their outer contour so as to allow by sliding to exert a force pushing said at least one float 18 during the passage of a armed position at a disarmed position of said at least one triggering device 9.

This step of initializing said at least one detergent container 7 in filling and emptying detergent position is to be implemented only in the case where said at least one detergent container 7 is in the closed position of an opening filling and emptying detergent 21 of said at least one detergent tank 7.

In the position of filling and emptying detergent and in the case where said at least one detergent container 7 is extractable, it can be put back in position on the detergent dispensing device 6 if it had been removed in the operating cycle of the previous washing machine 1, either filled with detergent directly on the detergent dispensing device 6, or removed from the detergent dispensing device 6 to be filled with detergent on the outside of the washing machine 1 since said at least one trigger device 9 is disarmed.

In the case where the at least one detergent container 7 is extractable, the driving element 12 and the detergent container 7 associated can be made in separate parts so that the detergent container 7 is extractable and that the driving element 12 is fixed on the axis of rotation 13 and free to rotate relative to the hubcap 10.

The method of operation of the detergent dispensing device 6 then comprises a step of rotating said at least one detergent container 7 from a position for disengaging the detergent filling and emptying opening 21 to a position sealing a filling opening and emptying detergent 21 of said at least one detergent tank 7 so as to reset said at least one trigger device 9.

This step of rotating said at least one detergent tank 7 is implemented by manually moving said at least one detergent tank 7 about its axis of rotation 13. The resetting of said at least one trigger device 9 is set by locking one end of the driving element 12 in a notch 15 of said at least one float 18 by virtue of the force exerted by the spring 14.

The spring 14 bears on the one hand said at least one float 18, and in particular at least one arm 18a, on the drive element 12 so as to maintain said at least one trigger device 9 in the armed position, and in turn causes said at least one detergent tank 7 to rotate through the driving element 12, and in particular the pad 20, from an armed position to a disarmed position of said at least one triggering device 9 .

The positioning of the at least one detergent tank 7 in the closed position of a filling and emptying opening 21 detects the detergent inside it until the displacement of the at least one float 18 upon reaching a water level threshold value in said at least one receptacle 8 triggering said at least one trigger device 9 from an armed position to a disarmed position.

The operating method of the detergent dispensing device 6 then comprises a step of filling and accumulating water of the at least one receptacle 8.

In a preferred embodiment, the step of filling and accumulating water of said at least one receptacle 8 is implemented by means of a water dispenser 17.

The water dispenser 17 sends at least one jet of water towards said at least one receptacle 8.

The operating method of the detergent dispensing device 6 comprises a step, as soon as the water level in said at least one receptacle 8 reaches a water level threshold value, for setting said at least one float 18 in motion by the water level reached in said at least one receptacle 8 so as to trigger said at least one trigger device 9 from an armed position to a disarmed position.

Then, the operating method of the detergent dispensing device 6 comprises a step of unlocking the drive element 12 so as to rotate said at least one detergent tank 7 by means of the spring 14.

The driving element 12 and said at least one detergent tank 7 are rotated by the spring 14 connected on the one hand to the axis of rotation 11 of said at least one float 18, integrally, and of on the other hand to the stud 20 of the driving element 12.

Thus, said at least one detergent container 7 is returned to the detergent emptying position so as to evacuate the detergent.

The detergent filling and emptying opening 21 of the at least one detergent container 7 having been used for the filling of detergent is now turned over so that the detergent flows by gravity.

The reversal of said at least one detergent container 7 promotes the emptying of the latter so as to avoid the agglomeration of detergent, especially powder, in the bottom thereof due to moisture.

The detergent delivery device 6 includes a stopper (not shown) of the at least one detergent container 7 in the detergent emptying position.

In one embodiment, the stop of said at least one detergent container 7 in the detergent emptying position can be achieved by a support of the driving element 12 on a rib of the hubcap 10.

There will now be described a detergent dispensing device according to the invention arranged in a washing machine to load the laundry from above.

Preferably, the detergent dispensing device 6 is mounted on the door 5 for closing the access opening 4 of the body 2 of the washing machine 1.

Thus, moving said at least one detergent container 7 of the detergent dispensing device 6 from the position of disengagement of the filling and emptying detergent opening 21 to the closed position of a filling opening and Detergent emptying 21 of said at least one detergent tank 7, and vice versa, can be performed when the door 5 of the body 2 of the washing machine 1 is in the open position.

After the detergent filling of said at least one detergent tank 7 of the detergent dispensing device 6, possibly following the putting back of said at least one detergent tank 7 on the detergent dispensing device 6 when said at least one tank detergent 7 is extractable, and following the rotational drive of said at least one detergent tank 7 from a position of disengagement of the filling opening and emptying detergent 21 to a closed position of a Detergent filling and emptying opening 21 of said at least one detergent tank 7, the door 5 of the body 2 of the washing machine 1 can be moved from an open position to a closed position.

Said at least one triggering device 9 of the detergent dispensing device 6 ensures that said at least one detergent container 7 is maintained in a detergent filling position following the closure of the door 5 of the bodywork 2 of the washing machine. 1, even when the latter is closed suddenly or when the washing machine 1 is put into operation and generates vibrations.

Following the closure of the door 5 of the body 2 of the washing machine 1, the detergent dispensing device 6 is disposed above the drum housed inside the washing tub 3 of the washing machine 1 .

In this way, the amount of at least one detergent dose contained in at least one detergent container 7 of the detergent dispensing device 6 is dispensed in the direction of the drum, and in particular the laundry load, by means of the same. minus a trigger device 9 activated by said at least one receptacle 8 fed with a quantity of water.

Following the closure of the door 5 of the body 2 of the washing machine 1, said at least one detergent tank 7 of the detergent dispensing device 6 is redirected an angle of the order of 90 ° to 110 °.

This reorientation of the at least one detergent tank 7 is due to the displacement of the door 5 of the body 2 of the washing machine 1 from a substantially vertical position to a substantially horizontal position.

Advantageously, the trim 10 retains the filled detergent in said at least one detergent tank 7 in the open and closed position of the door 5 and as the said at least one trigger device 9 is held in the armed position.

Thus, the detergent contained in said at least one detergent container 7 is retained by the hubcap 10, whether the detergent is in the form of powder, liquid or semi-liquid, as long as the at least one trigger device 9 is in the armed position. .

The rotational drive of said at least one detergent container 7 is controlled by the control means of the washing machine 1, in particular a microcontroller, allowing or not the water supply of said at least one receptacle 8 according to the cycle of selected operation of the washing machine 1.

Thus, the quantity of at least one detergent necessary for a cycle of operation of the washing machine 1 is poured into the washing tub 3 at a predetermined time and controlled by the control means of the washing machine 1.

Advantageously, following the supply of water to said at least one receptacle 8, the water accumulated in said at least one receptacle 8 is emptied by means of said at least one water discharge opening 19 formed in said at least one receptacle 8.

Thus, the water accumulated in said at least one receptacle 8 is emptied by means of said at least one water discharge opening 19 towards the washing tub 3 during the operating cycle of the washing machine 1 and is therefore not poured on the drum housed inside the washing tub 3 when opening the door 5 of the bodywork of the washing machine 1.

In this way, the laundry contained in the drum can not be wetted by the water accumulated in said at least one receptacle 8 following the last phase of the operating cycle of the washing machine 1, said last phase being generally a phase of spinning the laundry, when opening the door 5 of the body 2 of the washing machine 1.

In the embodiment as illustrated in figures 2 and 4 , the water discharged from said at least one receptacle 8 by means of said at least one water discharge opening 19 is also discharged from the hubcap 10 in the direction of the washing tub 3 since the wall comprising said at least one water discharge opening 19 is a common wall of said at least one receptacle 8 and the hubcap 10.

In an improved embodiment, following the rotation of said at least one detergent 7 in the disengaged position of a filling opening and emptying of detergent 21 of said at least one detergent tank 7 relative to the hubcap 10, and during driving in rotation of the drum at a speed of orization of the water contained in the washing tub 3, the water contained in the washing tub 3 is projected towards the detergent dispensing device 6 so as to clean the at least one detergent container 7.

Thus, the water contained in the washing tank 3 is projected against the detergent dispensing device 6, and in particular on the hubcap 10 and on said at least one detergent tank 7 during the rotation drive of the drum so that the movement of water is tangential to the latter, in particular during a spinning phase of an operating cycle of the washing machine 1.

In this way, the cleaning of said at least one detergent tank 7 is ensured by the inverted position of said at least one detergent tank 7 following the tilting of said at least one triggering device 9 and the projection of water contained in the washing tank 3 by means of the drum.

With the aid of the present invention, the detergent dispensing device makes it possible to rotate at least one detergent container by filling the water with at least one receptacle that sets a trigger device in motion regardless of the amount of detergent present in the detergent container. said at least one detergent container.

Of course, many modifications can be made to the embodiments described above without departing from the scope of the invention.

Thus, the washing machine may be a washing machine, a washing and drying machine, or a dishwashing machine.
