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 to the emptying position by changing the position of the its center of gravity.

The moment due to the mass of water in the counterweight water accumulation bag must be greater than that resulting from the presence of detergent in the accumulation bag of a detergent added to the couple resulting from contact friction of the compartment on the compartment rotation supports.

The torque generated by the presence of water in the pocket of water accumulation The counterweight must be greater than that exerted by the detergent in the detergent accumulation bag. And the torque differential generated on either side by each of the pockets of the compartment must be sufficient to overcome the contact friction between the compartment and the rotation supports thereof. This determination of the couples involved makes it possible to deduce the equilibrium point of the compartment and to determine the position of the partition wall between the counterweight water accumulation bag and the accumulation bag of a product of washing.

The amount of detergent to be introduced into the ladle of a detergent is known from the recommendations specified by the manufacturers of detergents and washing machines. The body of water and the resulting position of the centers of gravity with or without the accumulation of detergent in the accumulation pocket of a detergent compartment can thus be determined.

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, during the rotation of the compartment, the counterweight water contained in the counterbalance water accumulation bag is poured instantly and can therefore 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 describes a device dispensing detergent of a washing machine comprising at least one detergent container that can hold a quantity of detergent, at least one receptacle that can contain a quantity of water, wherein the at least one detergent container is rotated after filling in water of said at least one receptacle.

Advantageously, said at least one receptacle 8 comprises at least one water discharge opening 19.

Thus, 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 8. The emptying of said at least one receptacle 8 can thus be achieved slowly, that said at least one trigger device 9 is set in motion or not.

The minimum water flow rate of water supply of the at least one receptacle 8 must take into account the water leakage generated by the at least one water discharge opening 19 which increases as a function of the water column. present in said at least one receptacle 8.

The water leak generated by said at least one water discharge opening 19 is predetermined so as to allow the accumulation of water in said at least one receptacle 8 during the water supply of the latter, even when the flow of water supply water of said at least one receptacle 8 is low.

Thus, said at least one trigger device 9 is set in motion, then drives said at least one detergent tank 7 as soon as the amount of water accumulated in said at least one receptacle 8 exceeds a threshold value of water amount.

Here, as illustrated in Figures 4 and 5 , a water discharge opening 19 is formed in the bottom wall of a receptacle 8.

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 detergent emptying position 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 the at least one receptacle 8.

Said at least one detergent tank 7 is rotatably mounted on a support 28, illustrated in FIG. figure 4 .

The support 28 of the at least one detergent tank 7 serves to guide the axis of rotation 13 common to the least one detergent tank 7 and to the driving element 12.

The support 28 of the at least one detergent tank 7 also makes it possible to refer to the axis of rotation 11 of the tilting element 10 with respect to the axis of rotation 13 of the driving element 12 so that guaranteeing a predetermined distance between centers of rotation 11, 13.

In a preferred embodiment, the tilting element 10 comprises said at least one receptacle 8.

Here, the tilting element 10 and said at least one receptacle 8 are made in the same room, as illustrated in FIGS. Figures 4 to 7 , so as to guarantee the displacement of the tilting element 10 as soon as the mass of water accumulated in the at least one receptacle 8 has reached a threshold value of water quantity.

Preferably, the tilting element 10 is set in motion after exceeding the point of equilibrium between the tensile force of the spring 14, where the spring 14 exerts a torque relative to the axis of rotation 11 of the element of tilting 10, and the force exerted by the amount of water accumulated in said at least one receptacle 8 while taking into account the friction of contact between the tilting element 10 and the driving element 12 due to the pulling of the spring 14 on the driving element 12.

The torque exerted by means of the spring 14 relative to the axis of rotation 11 of the tilting element 10 is dependent on the distance a between the axis of rotation 11 of the tilting element 10 and an opening of retainer 15 of the spring 14 formed in the tilting element 10.

Here, the retaining opening 15 of the spring 14 is formed in a wall 16 of the tilting element 10 perpendicular to the axis of rotation 11 of the tilting element 10.

Advantageously, the tilting element 10 comprises a notch 25 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 7a .

In a detergent dispensing device 6 as illustrated in FIGS. Figures 1 to 7 the torque exerted by the mass of water contained in said at least one receptacle 8 forming part of the tilting element 10 must be greater than that exerted by the spring 14 connected to the driving element 12 added to the forces of friction of the driving element 12 on the tilting element 10, taking into account the torque that can be exerted by the tilting element 10.

Preferably, the center of gravity of the tilting element 10 is arranged between the axis of rotation 11 of the tilting element 10 and the notch 25 of the tilting element 10 allowing the retention of the tilting element. tilting 12 in filling position of said at least one detergent container 7.

And said at least one receptacle 8 forming part of the tilting element 10 is disposed on the opposite side of the axis of rotation 11 of the tilting element 10 with respect to the center of gravity of the tilting element 10.

Thus, according to the position of the center of gravity of the tilting element 10 between the axis of rotation 11 of the tilting element 10 and the notch 25 of the tilting element 10, where the tilting element 10 is set in motion by the amount of water accumulated in said at least one receptacle 8, the torque exerted by the spring 14 connected to the driving element 12 added to the frictional forces of the driving element 12 on the tilting element 10 opposes that exerted by the body of water contained in said at least one receptacle 8 forming part of tilting element 10.

Since the center of gravity of the tilting element 10 is disposed on the opposite side with respect to the axis of rotation 11 of the tilting element 10 where is located said at least one receptacle 8, said at least one triggering device 9 is held in the armed position by the force of the spring 14 opposing the force of gravity of said at least one receptacle 8 forming part of the tilting element 10 filled or not with water.

Such a positioning of the center of gravity of the tilting element 10 makes it possible to prevent inadvertent tripping of said at least one trigger device 9 so as to avoid an uncontrolled reversal of said at least one detergent tank 7, whether or not filled with detergent, especially during vibrations generated by the operation of the washing machine 1, during the movement and the closing of the door 5 in which is disposed the detergent dispensing device 6 for a washing machine laundry load from above.

The triggering of the rotation of said at least one detergent container 7 is carried out following the change of position of the center of gravity of the tilting element 10.

In the filling position of the at least one detergent container, the mass of the tilting element 10 is added to the force of the spring 14.

During the feeding and the accumulation of water in the at least one receptacle 8, an additional component is added so as to move the center of gravity of the tilting element 10 on the opposite side of the axis. rotation 11 of the tilting element 10 with respect to the position of said at least one detergent container 7.

In this way, the force of the spring 14 and the friction of the driving element 12 on the notch 25 of the tilting element 10 are overcome by the mass of water accumulated in the at least one receptacle 8 of so as to enable the rotation of the at least one detergent container 7 by the spring 14 and the drive element 12.

In one embodiment, said at least one trigger device 9 comprises a lever 23 coupled to said at least one detergent container 7 so as to drive said at least one detergent container 7 during arming of said at least one trigger device 9 .

Thus, said at least one detergent container 7 is rotated from a detergent emptying position to a detergent filling position by means of a lever 23 while driving said at least one trigger device 9 from a position disarmed to an armed position.

In addition, resetting said at least one trigger device 9 by means of the lever 23 makes it possible to rotate said at least one detergent container 7 from a detergent emptying position to a detergent filling position without having to touch directly. said at least one detergent container 7 can be coated with traces of detergent, as illustrated in FIGS. Figures 9a and 9b .

Preferably, the lever 23 is integral with the driving element 12.

Thus, the lever 23 is integral with the at least one detergent container 7.

In one embodiment, the lever 23 and the driving member 12 may be formed in a single piece.

The lever 23 is rotated about the axis of rotation 13 of the driving element 12 as well as said at least one detergent tank 7 following the setting in motion of the tilting element 10 by the amount of accumulated water in said at least one water receptacle 8 and in the rotational drive of the driving element 12 by the spring 14.

In this way, the lever 23 is rotated from the detergent filling position of the at least one detergent 7 to the detergent emptying position of the at least one detergent container 7.

Similarly, when said at least one detergent container 7 is extractable is removed from the detergent dispensing device 6, the lever 23 is rotated from the detergent filling position of the at least one detergent 7 to the emptying position of the detergent dispensing device 6. detergent of the at least one detergent container 7.

Therefore, the lever 23 is rotated about the axis of rotation 13 of the driving element 12 following the setting in motion of the tilting element 10 by the amount of water accumulated in the at least a water receptacle 8 and the driving in rotation of the driving element 12 by the spring 14 without said at least one detergent tank 7 being installed on the detergent dispensing device 6.

The resetting of said at least one trigger device 9 is carried out by pushing the lever 23 from the detergent emptying position of said at least one detergent container 7 to the detergent filling position thereof.

Thus, the lever 23 rotates the driving element 12 around the axis of rotation 13 against the restoring force of the spring 14 and locks the tilting element 10 in the armed position by positioning the element 12 in the notch 25 of the tilting element 10.

This resetting of said at least one trigger device 9 may be implemented with or without said at least one detergent tank 7 when the latter is extractable.

In one embodiment, when the lever 23 is returned to the detergent filling position of said at least one detergent container 7 and said at least one detergent container 7 is extractable, a slot 26a formed in the lever 23 cooperates with a rib 27 formed on a face 7d of said at least one detergent container 7, as illustrated in FIGS. Figures 9a and 9b .

The positioning of the rib 27 of said at least one detergent tank 7 in the slot 26a ensures that said at least one detergent tank 7 is maintained with respect to the detergent dispensing device 6 so as to avoid disengagement of said at least one detergent container 7.

In this embodiment, a device for holding said at least one detergent container 7 in the detergent dispensing device 6 as previously described is made only on one side 7d of said at least one detergent container 7 since the Lateral clearance between said at least one detergent container 7 and the hubcap 22 is minimized.

Of course, a device for maintaining said at least one detergent container 7 in the detergent dispensing device 6, as described above, can be arranged on both faces 7d of said at least one detergent container 7.

We will now describe, in particular with reference to Figures 7a to 7d , a method of operation of a detergent dispensing device according to the invention.

The operating method of the detergent dispensing device 6 firstly comprises a step of initializing said at least one detergent container 7 in the detergent filling position.

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

Said at least one jet of water leaving the water dispenser 17 can be channeled by a deflector 18 so as to orient the at least one jet of water in the at least one receptacle 8.

Preferably, said at least one jet of water leaving the deflector 18 is oriented towards the bottom of said at least one receptacle 8 so as to exert a torque with respect to the axis of rotation 11 of the tilting element 10.

Thus, the torque exerted by the at least one jet of water leaving the deflector 18 on the tilting element 10 facilitates the tilting of the latter around its axis of rotation 11.

The operating method of the detergent dispensing device 6 comprises a step, as soon as the quantity of water accumulated in the at least one receptacle 8 reaches a threshold value of the amount of water, the setting in motion of the the tilting element 10 by the mass of water contained in said at least one receptacle 8 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 the at least one detergent tank 7 are rotated by the spring 14 connected on the one hand to a retaining opening 20 of the driving element 12 and on the other hand to the retaining opening 15 of the tilting element 10.

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 of said at least one detergent container 7 in the detergent emptying position.

The stop of said at least one detergent container 7 in the detergent emptying position is achieved by the support 28 of said at least one detergent container 7.

In one embodiment, the stop of said at least one detergent container 7 may comprise a boss formed on the support 28 so as to limit the rotation of the driving element 12 around the axis of rotation 13 in the detergent emptying position of the at least one detergent container 7.

In another embodiment, the stop may comprise two bosses formed on the support 28 bearing respectively with two outer walls of the driving element 12 disposed on either side of the axis of rotation 13 of the drive element 12. These two bosses are schematically represented by rectangles in dotted lines on the Figure 7c since the support 28 has been removed to facilitate reading thereof.

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, the movement of said at least one detergent tank 7 of the detergent dispensing device 6 from the detergent emptying position to the detergent filling position, and vice versa, can be effected 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 container 7 of the detergent dispensing device 6, and possibly following the putting back of said at least one detergent container 7 on the detergent dispensing device 6 when said at least one detergent tank 7 is extractable, 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 reoriented by 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, said at least one rib 7c of said at least one detergent container 7 holds the detergent filled in said at least one detergent container 7 in the open and closed position of the door 5 and as long as said at least one trigger device 9 is maintained in armed position.

Thus, the detergent contained in said at least one detergent container 7 is retained by at least one rib 7c of said at least one detergent container 7, whether the detergent is in the form of powder, liquid or semi-liquid, as long as said minus a triggering 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 1 to 7 , the water discharged from said at least one receptacle 8 by means of said at least one water discharge opening 19 is then discharged through the water discharge openings 24 of the hubcap 22 in the direction of the tank. washing 3.

In an improved embodiment, following the rotation of the at least one detergent tank 7 in the detergent emptying position, and during the rotation of the drum at a speed of orisation of the water contained in the tank of washing 3, it is projected towards the detergent dispensing device 6 so as to clean said 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 22 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 the at least one detergent container 7 is ensured by the inverted position of said at least one detergent tank 7 following the tilting of said at least one trigger device 9 and the projection of water contained in the washing tank 3 by means of the drum.

In the case where said at least one detergent container 7 is extractable, the cooperation of the rib 27 of said at least one detergent container 7 with the slot 26a formed in the lever 23 makes it possible to retain said at least one detergent container 7 of so that it can not disengage from the detergent dispensing device 6 in the detergent emptying position, and guide it when it is placed on the detergent dispensing device 6.

The opening of the slot 26a of the lever 23 is closed by the bottom of the slot 26b of the hubcap 22 following the rotation of the at least one detergent tank 7 about its axis of rotation 13 from the filling position of detergent to the detergent emptying position so as to avoid the withdrawal of the at least one detergent container 7 during and after this rotation, as illustrated by the Figures 9a , 10 and 11 .

In the case of a washing machine laundry loading from above, the cooperation of the rib 27 of said at least one detergent tank 7 with the slot 26a formed in the lever 23 also retains said at least one detergent tank 7 so that it can not disengage from the detergent dispensing device 6 after closing the door 5 that said at least one detergent tank 7 is in the detergent filling position or in the emptying position of detergent with respect to the detergent dispensing device 6.

The slot 26a of the lever 23 is oriented at an angle α, in particular of the order of 45 °, relative to a horizontal axis A passing through the axis of rotation 13 upwards when the door 5 is in the closed position. as shown in figure 9b .

In this way, following the rotation of the door 5 from the open position to the closed position about its axis of rotation, the withdrawal of said at least one detergent container 7 during and after this rotation of the door 5 is avoided by the inclination of the slot 26a of the lever 23 upwards.

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.
