These fastening means are well known to those skilled in the art and do not need to be described in more detail here. A hydraulic water distribution circuit of a washing machine according to one embodiment of the invention will now be described with reference to Figs. 1 to 5 and Fig. 8.

Figures 2 to 5 illustrate the water reservoir 6 according to the different phases of water circulation in the hydraulic water distribution circuit. For the purpose of simplifying the representation of the water tank 6 with the various hydraulic control members in these FIGS. 2 to 5, the second water circulation pump 12 and the valve 14 are shown opposite the the inner face of the wall 6a of the water tank 6 while these are preferably arranged against the outer face of the wall 6b of the water tank 6, as shown in Figure 8. The water tank 6 comprises at least one passage opening 42 disposed in the upper part of the water tank 6, and through which a stream of water is directed towards the interior of the water tank 6. The water tank 6 comprises at least one deflection member of a water flow 19a, 19b disposed within the water reservoir 6 so as to deflect the direction of a flow of water flowing from said at least one opening of passage 42 of the water reservoir 6 towards the interior of the water tank 6, and in particular in the water storage and / or rinsing zone 6c of the water tank 6. Thus, said at least one deflection element of a water flow 19a, 19b disposed inside the reservoir of water 6 prevents a projection of water on the upper surface N2 of the amount of water present inside the water tank 6 during the water filling phase of the water tank 6.

In this way, the noise generated by the water inlet during the water filling of the water tank 6 is minimized. Preferably, said at least one deflection element of a water flow comprises at least one break wall of a water flow 19a disposed opposite said at least one passage opening 42 of the water reservoir. water 6 so as to break the projection of water from said at least one passage opening 42 of the water reservoir 6. Thus, said at least one breaking wall of a water flow 19a can break a flow of water entering the water reservoir 6 so as to divide it and to avoid the impact of a single flow of water on the upper surface N2 of the amount of water present inside the water reservoir. In this way, said at least one breaking wall of a water flow 19a makes it possible to multiply the number of points of impact on the upper surface N 2 of the quantity of water present inside the water tank 6. Preferably, said at least one deflection element of a water flow comprises at least one guide wall of a n water flow 19b so as to guide the projection of water from said at least one passage opening 42 of the water reservoir 6 against an inner wall 20 of the water reservoir 6, where the inner wall 20 of the - 12- water tank 6 extends along the height of the water reservoir 6. Thus, said at least one guide wall of a water flow 19b can guide a stream of water entering the reservoir of water. water 6 against an inner wall 20 of said water reservoir 6 so as to widen the impact zone of a water flow on the upper surface N2 of the amount of water present inside the reservoir of water 6. Here, the inner wall 20 of the water tank 6 against which flows the water flow guided by said at least one guide wall of a water flow 19b is a wall of the pipe too much 9. Advantageously, said at least one breaking wall of a stream of water 19a extends vertically inside the water tank 6 according to the height of the water tank. 6. Thus, the flow of water broken by said at least one breaking wall of a stream of water 19a flows vertically inside the water reservoir 6. Preferably, said at least one break wall a flow of water 19a is disposed above said at least one guide wall of a water flow 19b according to the height of the water reservoir 6. Thus, the flow of water broken by said at least a breaking wall of a stream of water 19a flows towards said at least one guide wall of a stream of water 19b. Advantageously, said at least one guide wall of a water flow 19b is inclined up and down along the height of the water tank 6.

Thus, the flow of water guided by said at least one guide wall of a water flow 19b flows by gravity along it so as to come into contact with the inner wall 20 of the reservoir. water 6 and flow along said inner wall 20. Advantageously, said at least one wall for guiding a water flow 19b extends between two opposite walls 6a, 6b of the water tank 6.

Thus, said at least one guide wall of a water flow 19b makes it possible to guide almost all the flow of water leaving said at least one through opening 42. The water reservoir 6 comprises a venting 26 so as to allow filling and emptying water of the water tank 6. In a preferred embodiment, said at least one breaking wall of a stream of water 19a is at least one rib formed in a wall 6a, 6b of the water tank 6. Thus, said at least one rib 19a formed in a wall 6a, 6b of the water tank 6 allows an air passage in the upper part of the tank of water 6 on either side of said at least one rib 19a while breaking the jet of water projected against it from said at least one through opening 42, in particular when the water level inside of the water tank 6 reaches the maximum permissible water level N1 in said water tank 6. Said at least one wall d The breaking of a stream of water constituted by at least one rib 19a extends only partially between two opposite walls 6a, 6b of the water tank 6. Consequently, the realization of said at least one rib a breaking wall of a stream of water 19a is simple to perform and inexpensive.

The passage of air in the upper part of the water tank 6 on either side of the said at least one rib 19a is in fluid communication with the venting device 26 of the water tank 6, in particularly with said at least one air passage opening 44 of the venting device 26 formed in a wall 6b of the water tank 6.

In this way, the water level inside the water tank 6 is not limited to the lower point of said at least one rib 19a since a flow of air can flow through the water storage device. venting 26 of the reservoir 6 and on either side of said at least one rib 19a. Therefore, the water tank 6 can be filled with water up to its maximum allowable water level N1. The upper part of the water tank 6 is thus separated into two zones on either side of the said at least one rib 19a. In a first zone provided with the device for venting the water tank 6, when the water tank 6 is filled with water from the washing tank 3, the air present in this first zone of the water reservoir 6 water 6 is evacuated through the venting device 26 of the water tank 6. In a second zone devoid of a device for venting the water tank 6, during filling with water of the water tank 6 from the washing tank 3, the air present in this second zone of the water tank 6 flows through the air passage formed by the at least one rib 19a formed in a wall 6a. 6b of the water tank 6, then this air is evacuated through the venting device 26 of the water tank 6, in particular from the moment when the water level in the water tank 6 reaches the lower point of said at least one rib 19a. The embodiment of the at least one break wall of a stream of water in the form of at least one rib 19a formed in a wall 6a, 6b of the water tank 6 makes it possible to compensate for the case where a break wall a stream of water extends from an upper wall of the water tank 6 and between two opposite walls 6a, 6b of the water tank 6, in particular in the form of a partition, preventing an air flow can flow on either side as soon as the water level in the water tank 6 reaches the lower point of the breaking wall of a stream of water. In this case, the zone delimited by the breaking wall of a water flow not being in fluid communication with the venting device 26 of the water reservoir 6 would have constituted a closed space without circulation. -14- air. As a result, the water introduced into the water reservoir 6 could have gone up to the maximum permissible water level N1 only in the zone delimited by the break wall of a water flow being in use. in fluid communication with the venting device 26 of the water tank 6.

Here, said at least one rib 19a formed in a wall 6a, 6b of the water tank 6 extends from the upper wall of the water tank 6 to the lower part of the water tank 6. And the lower point of said at least one rib 19a is located below the maximum allowable water level N1 within the water tank 6. In this embodiment, the maximum allowable water level N1 within the water reservoir water 6 is defined by the water inlet opening 17 of the overflow pipe 9. The maximum permissible water level N1 inside the water reservoir 6 is thus just below the water inlet opening 17 of the overflow pipe 9 so as to define a level of water overflow through said water inlet opening 17 of the overflow pipe 9 during filling with water of the water tank 6 from the washing tank 3. Advantageously, at least a first rib 19a is formed in a prem 6a of the water tank 6 and at least one second rib 19a is formed in a second wall 6b of the water tank 6 so as to form a baffle allowing an air passage in the upper part of the water tank 6 on either side of the first and second ribs 19a. Thus, the passage of air in the upper part of the water reservoir 6 on either side of the first and second ribs 19a and between them is in fluid communication with the vent device 26 of the reservoir. of water 6, in particular with said at least one air passage opening 44 of the venting device 26 formed in a wall 6b of the water tank 6. In this way, the water level at the interior of the water tank 6 is not limited to the lower point of the first and second ribs 19a since a flow of air can flow through the vent device 26 of the water tank 6, on either side of said first and second ribs 19a and between them.

Therefore, the water tank 6 can be filled with water up to its maximum allowable water level N1. The upper part of the water reservoir 6 is thus separated into two zones on either side of the first and second ribs 19a. In a first zone provided with the device for venting the water tank 6, when the water tank 6 is filled with water from the washing tank 3, the air present in this first zone of the water reservoir 6 water 6 is evacuated through the venting device 26 of the water tank 6. In a second zone devoid of a device for venting the water tank 6, during the filling the water tank 6 with water from the washing tank 3, the air present in this second zone of the water tank 6 flows through the air passage formed by the first and second ribs 19a formed respectively in the first and second walls 6a, 6b of the water tank 6, then this air is discharged through the venting device 26 of the water tank 6, in particular from the moment when the level of water in the water tank 6 reaches the lower point of the first and second ribs 19a. Preferably, the first and second walls 6a, 6b of the water reservoir 6 respectively comprising the first and second ribs 19a are two opposite walls 6a, 6b of the water reservoir 6. Advantageously, the first and second ribs 19a formed respectively in the first and second walls 6a, 6b of the water tank 6 are arranged along the width of the water tank 6.

Here and in no way limiting, the first wall 6a of the water tank 6 comprises two first ribs 19a and the second wall 6b of the water tank 6 comprises a second rib 19a. The second rib 19a of the second wall 6b of the water tank 6 is disposed between the first two ribs 19a of the first wall 6a of the water tank 6 when the two walls 6a, 6b of the water tank 6 are joined together. . Said first and second ribs 19a formed respectively in the first and second walls 6a, 6b of the water tank 6 allow an air passage in the upper part of the water tank 6 on either side of said ribs 19a while breaking the jet of water sprayed against them from said at least one passage opening 42. Particularly, said first and second ribs 19a formed respectively in the first and second walls 6a, 6b of the water tank 6 allow a passage of water. air in the upper part of the water tank 6 when the water level inside the water tank 6 reaches the maximum permissible water level N1 in said water tank 6, and in particular as soon as the water level inside the water tank 6 reaches the lower point of the first and second ribs 19a located below the maximum permissible water level N1 in the water tank 6. Said first and second ribs 19a respectively extend only partially between the two opposite walls 6a, 6b of the water tank 6.

In one embodiment, said at least one deflection element of a water flow 19a is disposed between said at least one through opening 42 disposed in the upper part of the water reservoir 6 and the setting device. Thus, said at least one deflection member of a water flow 19a disposed inside the water tank 6 prevents a water projection at the water reservoir 26. through the venting device 26 of the water tank 6.

In this way, said at least one deflection member of a water flow 19a disposed within the water tank 6 ensures the flow of air through the venting device 26 of the water tank 6 avoiding an obstruction thereof by splashing water from a flow of water passing through said at least one through opening 42 disposed in the upper part of the water tank 6.

In another embodiment, the venting device 26 of the water tank 6 is disposed between said at least one through opening 42 disposed in the upper part of the water tank 6 and said at least one element of deviation of a stream of water 19a. The hydraulic water distribution circuit comprises a high point formed between the water tank 6 and the washing tub 3 of the washing machine 1. The high point 25 of the hydraulic water distribution circuit is located at the same height or above the maximum permissible water level N1 inside the water tank 6. The high point 25 formed between the water tank 6 and the washing tub 3 of the washing machine 1 allows to prevent decanting of the washing and / or rinsing water from the washing and / or rinsing water tank 6 to the washing tank 3, and vice versa, by a communicating vessel phenomenon. The hydraulic water distribution circuit comprises the first water circulation duct 10 formed inside the water tank 6. The high point 25 is formed by the first water circulation duct 10 arranged at the Inside the water tank 6. The first water circulation pipe 10 thus forms a high point 25 located at the same height or above the maximum permissible water level N1 within the water tank 6 The high point 25 of the first water circulation pipe 10 comprises said at least one through opening 42 opening inside the water tank 6, and in particular opening into the washing water storage zone. and / or rinsing 6c of the water tank 6, so as to defuse a transfer of washing and / or rinsing water between the water tank 6 and the washing tank 3 of the washing machine 1, and Conversely.

And the venting device 26 of the water tank 6 is in fluid communication with said at least one through opening 42 of the first water circulation pipe 10 formed inside the water tank 6 Thus, said at least one passage opening 42 of the first water circulation pipe 10 formed inside the water tank 6 opens into the water tank 6 so as to defuse returning the washing and / or rinsing water stored in the water tank 6 to the washing tub 3 of the washing machine 1, and vice versa, allowing an introduction of air into the first circulation pipe water 10 formed inside the water tank 6 through said at least one through opening 42. Said at least one through opening 42 allows to draw air from the water tank 6 , especially in the area of the water reservoir 6 located between the maximum water level ad N1 missible and the upper wall of the water tank 6, so as to defuse the transfer by siphonage of the washing water and / or rinsing between the water tank 6 and the washing tub 3 of the washing machine 1. The high point 25 formed by the first water circulation conduit 10 formed inside the water tank 6 and disposed between the water tank 6 and the washing tub 3 of the washing machine 1 allows stopping the transfer by siphonage of the washing and / or rinsing water from the water tank 6 to the washing tub 3 of the washing machine 1, and vice versa, following the stopping of a washing pump; circulating water 11, 12 circulating the washing and / or rinsing water between the water tank 6 and the washing tank 3.

In particular, this high point 25 formed by the first water circulation pipe 10 formed inside the water tank 6 and disposed between the water tank 6 and the washing tank 3 of the washing machine 1 it makes it possible to stop the siphoning of the washing and / or rinsing water from the water tank 6 to the washing tank 3 of the washing machine 1, and vice versa, following the stopping of a pump circulating water 11, 12 and before the closing of at least one valve 14 disposed respectively between the water tank 6 and the washing tub 3. Such a washing machine equipped with a wash water tank and / or rinsing makes it possible to drain a partial amount of washing and / or rinsing water from the water tank 6 to the washing tank 3, and vice versa.

The quantity of washing and / or rinsing water circulated between the water tank 6 and the washing tank 3, and vice versa, can thus be controlled by a control unit of the washing machine 1. air introduced through said at least one passage opening 42 in the first water circulation conduit 10 formed inside the water tank 6 circulates inside the water tank 6 from the setting device in the air 26 of the water reservoir 6 to said at least one through opening 42 of the first water circulation conduit 10. Said at least one through opening 42 of the first circulation conduit of the first water 10 formed inside the water tank 6 thus creates an air passage from the outside of the water tank 6 towards the inside of the hydraulic water distribution circuit through the tank of water. water 6.

Said at least one passage opening 42 formed in the first water circulation duct 10 also makes it possible to directly evacuate a portion of the water flowing in the first water circulation duct 10 inside the tank. water 6 while avoiding an additional connection between said at least one passage opening 42 formed at the high point 25 of the first water circulation pipe 10 and a recovery zone of this quantity of water evacuated so as to simplify the hydraulic water distribution circuit and to minimize the cost of obtaining it. In this way, the fluid communication between said at least one through opening 42 of the first water circulation conduit 10 formed inside the water tank 6 and the air vent device 26 of the water reservoir water 6 makes it possible to fill and empty water for washing and / or rinsing the water tank 6 reliably, simply and inexpensively. Said at least one passage opening 42 formed at the high point 25 of the hydraulic water distribution circuit between the washing tank 3 and the water tank 6, where the high point 25 is formed by the first circulation pipe of water 10 formed inside the water tank 6, and the fluidic communication of said at least one through opening 42 with the venting device 26 of the water tank 6 makes it possible to to avoid a decrease in the level of water inside the water tank 6 following its filling of water from the washing tank 3 caused by a phenomenon of siphoning of the water contained in the water tank 6 towards the washing tank 3 following the stopping of said at least one water circulation pump 11 for filling the water tank 6 with water from the washing tank 3, in particular the first water circulation pump 11 This phenomenon of siphoning water contained in the water tank 6 to the washing tub 3 following the stopping of said at least one water circulating pump 11 is defused by the introduction of air into said at least one through opening 42 of the first circulation duct. water 10 formed inside the water tank 6, where the air is introduced beforehand into the water tank 6 by the vent device 26 of the latter.

Therefore, the water level inside the water tank 6 remains stable as soon as the at least one water circulation pump 11 is stopped, allowing the water tank 6 to be filled with water from the tank washing 3 regardless of the closing time of said at least one valve 14, and in particular of the closure of the water flow passage 40b by the valve 30, where the valve 30 is displaced by the actuator 27b. In addition, the positioning of the high point 25 of the hydraulic water distribution circuit inside the water tank 6 and the formation thereof by a first water circulation pipe 10 arranged inside the water tank 6 minimizes the space occupied by the hydraulic water distribution circuit and the water tank 6. Furthermore, such a construction of the hydraulic water distribution circuit between the washing tub 3 of the washing machine 1 and the water tank 6 is simplified and eliminates a device for closing and opening the venting device 26 of the water tank 6 and a sensor water level detecting the maximum water level in the water tank 6. Such a construction of the water distribution hydraulic circuit between the washing tub 3 of the washing machine 1 and the water tank 6 also allows to have a water tank 6 inside the body 2 of the washing machine 1 extending in height from a bottom wall 2c to an upper wall 2b of the body 2 of the washing machine 1. Practically, the high point 25 of the first water circulation pipe 10 is disposed at the junction between first and second portions 10a, 10b of the first water circulation duct 10, wherein the first and second portions 10a, 10b of the first water circulation duct 10 extend. respectively inside the water tank 6 and from the lower part to the upper part of the water tank 6. Thus, the two parts 10a, 10b constituting the first water circulation pipe 10 are integrated into the inside the water tank 6 and connected together so as to form the high point 25 of the hydraulic water distribution circuit between the water storage area 6c of the water tank 6 and the washing tank 3 of the machine 1. In this way, the a construction of the hydraulic water distribution circuit is simplified and allows to limit the use of flexible pipes from a hydraulic member in which is formed the high point of the hydraulic water distribution circuit to the water tank and to the washing tub of the washing machine. Preferably, said at least one through opening 42 is located at the top of the high point 25 formed by the first water circulation duct 10 formed inside the water tank 6.

Thus, during the circulation of the washing and / or rinsing water inside the first water circulation pipe 10, the amount of washing and / or rinsing water evacuated by said minus a passage opening 42 to the inside of the water reservoir 6 is minimized. In addition, such a positioning of said at least one through opening 42 makes it possible to prevent an entry of washing and / or rinsing water coming from the water tank 6 into the first water circulation duct 10 provided at inside the water tank 6, when the water level inside the water tank 6 exceeds the maximum permissible water level N1, and in particular when the water level inside the water tank 6 water tank 6 exceeds the inlet opening 17 of the overflow pipe 9 formed inside the water tank 6. Said venting device 26 of the water tank 6 comprises at least an air passage opening 44 formed in a wall 6b of the water tank 6. Advantageously, said at least one deflection element of a water flow 19a is disposed between said at least one passage opening 42 of the first water circulation conduit 10 formed inside the water tank 6 and said at least one e air passage opening 44 of the venting device 26 of the water tank 6, so as to deflect a flow of water flowing from said at least one through opening 42 of the first conduit of water flow 10 towards said at least one air passage opening 44 of the air reservoir 26 of the water reservoir 6. Thus, said at least one deflection element of a flow of water water 19a disposed inside the water tank 6 prevents a water projection through the vent device 26 of the water tank 6. In this way, said at least one element of deviation of a stream of water 19a disposed inside the water tank 6 ensures the flow of air through the vent device 26 of the water tank 6 avoiding an obstruction of the latter by splashing water from a stream of water passing through said at least one through opening 42 of the first circulation pipe 10 in another embodiment, said at least one air passage opening 44 of the venting device 26 of the water reservoir 6 is disposed between said at least one passage opening 42 of the first water circulation conduit 10 formed inside the water reservoir 6 and said at least one deflection element of a water flow 19a. Advantageously, the venting device 26 of the water tank 6 comprises an air flow tube 36 connected to a zone 37 in fluid communication with the washing tank 3 of the washing machine 1.

Thus, the washing and / or rinsing water tank 6 comprises a venting device 26 making it possible to fill and empty wash and / or rinse water inside the tank. -this. The water tank 6 is vented by the air flow tube 36 connecting the water tank 6 to the washing tub 3 of the washing machine 1. In addition, the venting device 26 of the water tank 6 is in fluid communication with the at least one air passage opening 42 of the first water circulation pipe 10 formed inside the tank of water 6 so as to defuse the return of the washing water and / or rinsing stored in the water tank 6 to the washing tub 3 of the washing machine 1, and vice versa, allowing an introduction of air in said first water circulation conduit 10. In this way, the hydraulic water distribution circuit between the washing tub 3 of the washing machine 1 and the water tank 6 is simple and inexpensive. The washing tub 3 of the washing machine 1 comprises an appropriate venting device 43 known per se which need not be described in more detail here. Advantageously, the zone 37 in fluid communication with the washing tank 3 of the washing machine 1 connected to the air flow tube 36 of the air-venting device 26 of the water tank 6 is a distributor of water supply (not shown) of the washing machine 1. In one embodiment, the water supply distributor supplies water to compartments of a detergent box. This water supply distributor can be in particular a rotary nozzle distributor.

Here, the water flow section of the airflow tube 36 of the venting device 26 of the water tank 6 is smaller than the water flow section of the overflow pipe. 9. During the filling of the water tank 6 with washing water and / or rinsing water from the washing tub 3, the air flow tube 36 of the air reservoir 26 water 6 can be filled with water when the water level in the water tank 6 exceeds the maximum permissible water level N1 therein. The amount of water introduced into the airflow tube 36 of the venting device 26 of the water tank 6 is less than the amount of water discharged through the overflow pipe 9 and does not exceed does not cause an extension of the emptying time of the washing tub 3 to the water tank 6 relative to the amount of water circulated between the washing tub 3 and the water tank 6. In another mode embodiment, the zone 37 in fluid communication with the washing tank 3 of the washing machine 1 where the air flow tube 36 opens out can be either the wash tank 3 itself, or a chamber connecting a detergent dispenser to the washing tub 3, either a chamber of a detergent dispenser or at a connection cuff of the washing tub 3 to the body 2 of the washing machine 1. -22- Well understood, the examples of zone in fluid communication with the wash tub of the washing machine defined are not limiting and can be different. The zone 37 in fluid communication with the washing tub 3 of the washing machine 1 where the air flow tube 36 opens out is situated above the maximum permissible water level N3 in the washing tub 3. the position of the zone 37 in fluid communication with the washing tub 3 of the washing machine 1 above the maximum permissible water level N3 in the washing tub 3 makes it possible to avoid a phenomenon of sound turbulence related to an air inlet from the water tank 6 through the air flow tube 36 below the water level in the washing tub 3, and can be amplified by the wash tub 3 itself, particularly when filling the washing tank with water and / or rinsing water 6 from the washing tub 3. In addition, the position of the zone 37 in fluid communication with the washing tub 3 of the washing machine 1 above the maximum permissible water level N3 in the washing tub 3 avoids a circulation of e through the air flow tube 36 to the water tank 6, in particular during a phase of an operating cycle of the washing machine 1. In this way, the washing water and / or rinsing stored in the water tank can not be soiled by washing water and / or rinse the washing tub 3 used during a phase of an operating cycle of the washing machine. 1 and not being intended to be stored in the water tank 6. By way of non-limiting example, the air flow tube 36 of the vent device 26 of the water tank 6 is connected directly to said at least one air passage opening 44 formed in a wall 6b of the water tank 6. And the air flow tube 36 of the air vent device 26 Water 6 is directly connected to at least one air passage opening in the water supply manifold. The air flow tube 36 of the venting device 26 of the water tank 6 is of smaller section than that of one of the water flow lines 7, 8, 9, 10. Water flow lines 7, 8, 9, 10 may have a diameter of the order of 15mm to 20mm and the airflow tube 36 may have a diameter of 2mm to 5mm. Of course, the values of the water flow pipes and the air flow tube are in no way limiting and may be different. The hydraulic water distribution circuit comprises an overflow pipe 9 formed inside the water tank 6. The overflow pipe 9 formed inside the water tank 6 is put into operation. fluidic communication with an external wastewater network 13. Thus, such a washing machine 1 having a wash water tank and / or rinse 6 where the hydraulic water distribution circuit of the washing machine 1 comprises an overflow pipe 9 formed inside the water tank 6 and placed in fluid communication with an external waste water network 13 makes it possible to dispense with a water level sensor mounted on the reservoir of water water 6 detecting the high water level inside the water tank 6. In this way, the filling of the water tank with water and / or rinsing water 6 from the washing tank 3 of the water tank 6. washing machine 1 is performed by activating said at least one water circulation pump 11 without control the water level inside the water tank 6. In the case where the amount of washing and / or rinsing water present in the washing tank 3 of the washing machine 1 is greater than the 6, the surplus water is discharged directly into an external wastewater network 13 by means of the overflow pipe 9 formed inside the water tank 6. such washing machine 1 having a wash and / or rinse water tank 6 is less expensive and easier to assemble. The overflow pipe 9 comprises a water inlet opening 17.

Preferably, stopping said at least one water circulation pump 11, during the filling of washing water and / or rinsing of the water tank 6 from the washing tub 3 of the washing machine 1, is controlled by a control unit of the washing machine 1 following at least the detection of a low level of water in the washing tub 3.

Thus, the control unit makes it possible to control the level of water inside the washing tub 3 and to detect the low level of water in the washing tub 3 when filling the wash water and / or rinsing the water tank 6 from the washing tub 3 so as to generate a stop command of said at least one water circulation pump 11 as soon as the low level of water is detected in the washing tub 3 .

In practice, the detection of a low level of water in the washing tank 3 of the washing machine 1 is carried out by means of a water level sensor 21 mounted on the washing tub 1 and connected functionally. to the control unit of the washing machine 1. Thus, the cost of obtaining the washing machine 1 having a wash water tank and / or rinse 6 is not increased by the level sensor water 21 mounted on the washing tub 3 since it is already present on the washing machines to control the water level inside the washing tub 3. -24- By way of example no In a limiting manner, the water level sensor 21 mounted on the washing tub 3 may be an electromechanical pressure switch making it possible to identify at least a low level and a high level of washing and / or rinsing water in the washing tub. 3, or a continuous pressure sensor, for example of the analog type, for measuring the height of washing water and / or rinse water. 3. Advantageously, the water inlet opening 17 of the overflow pipe 9 is located below said at least one air passage opening 44 of the setting device. air 26 of the water tank 6 according to the height of the water tank 6. Thus, the overflow pipe 9 formed inside the water tank 6 allows to evacuate a surplus of water introduced into the reservoir water 6 to the external waste water network 13, in particular by means of said at least one valve 14 and the drain line 8, while preventing a flow of water flowing through said at least one air passage opening 44 of the venting device 26 of the water reservoir 6 which can cause a disturbance of the flow of air flowing through the at least one air passage opening 44 of the venting device 26 of the water tank 6 when filling the water reservoir with water 6. Moreover, in the case where a more water introduced into the water tank 6 can not be discharged through the overflow pipe 9 formed inside the water tank 6, this excess water can be evacuated by the setting device. air 26 of the water reservoir 6 when it is connected to the zone 37 in fluid communication with the washing tank 3 by means of the air flow tube 36. Advantageously, the inlet opening of water 17 of the overflow pipe 9 is situated above the lower part of the at least one deflection wall of a water stream 19a along the height of the water tank 6.

Preferably, said at least one deflection member of a water flow 19a is disposed between said at least one through opening 42 of the first water circulation conduit 10 formed inside the water reservoir 6 and the water inlet opening 17 of the overflow pipe 9, so as to deflect a flow of water flowing from said at least one through opening 42 of the first water circulation pipe 10 into direction of the water inlet opening 17 of the overflow pipe 9. Thus, said at least one deflection element of a water flow 19a disposed inside the water tank 6 allows the to avoid a projection of water through the water inlet opening 17 of the overflow pipe 9. In this way, said at least one deflection element of a water flow 19a disposed at the interior of the water tank 6 avoids an obstruction thereof by splashing water from a cross-flow of water said at least one passage opening 42 of the first water circulation conduit 10 formed inside the water reservoir 6. In one embodiment, said at least one deflection element of a water flow 19a disposed between said at least one through opening 42 of the first water circulation conduit 10 formed inside the water reservoir 6 and said at least one air passage opening 44 of the device 26 of the water tank 6 is the same as said at least one deflection element of a water flow 19a disposed between said at least one through opening 42 of the first circulation pipe of water 10 formed inside the water tank 6 and a water inlet opening 17 of the overflow pipe 9.

The first water circulation pipe 10 formed inside the water tank 6 is connected with the at least one valve 14 mounted on the water tank 6. The first water circulation pipe 10 forms the point high 25 located at the same height or above the maximum permissible water level N1 inside the water tank 6.

Advantageously, the high point 25 of the first water circulation pipe 10 is located at the same height as the water inlet opening 17 of the overflow pipe 9 along the height of the water tank 6. Thus, the high point 25 of the first water circulation pipe 10 is aligned with the water inlet opening 17 of the overflow pipe 9 along the height of the water tank 6 so as to maximize the water capacity of the water tank 6. A positioning of the water inlet opening 17 of the overflow pipe 9 below the high point 25 of the first water circulation pipe 10 according to the height of the water tank 6 would cause a decrease in the water capacity of the water tank 6, that is to say that the position of the maximum allowable water level N1 in the water tank 6 would be lower. Positioning the water inlet opening 17 of the overflow pipe 9 above the high point 25 of the first water circulation pipe 10 according to the height of the water tank 6 would cause a delay of the evacuation of the excess washing and / or rinsing water introduced into the water tank 6 from the washing tub 3, that is to say that the amount of washing and / or rinsing water introduced into the water tank 6 would exceed the maximum permissible water level N1 in the water tank 6. The excess wash water and / or rinse introduced into the water tank 6 and exceeding the opening input 17 of the overflow pipe 9 would be evacuated by it. While the excess wash water and / or rinse introduced into the water tank 6 and between the high point 25 of the first water circulation pipe 10 and the inlet opening 17 of the overflow pipe 9 according to the height of the water tank 6 would be evacuated by the first water circulation pipe 10 to the washing tank 3 following the stopping of the first water circulation pump 11 , and in particular before closing the water flow passage 40b by the valve 30 of the valve 14. The overflow line 9 is connected to said at least one valve 14 mounted on the water tank 6.

Said at least one valve 14 is connected to a drain line 8. The drain line 8 is in fluid communication with an external wastewater network 13. Preferably, the overflow pipe 9 formed inside the reservoir water 6 and the venting device 26 of the water tank 6 are independent.

Thus, the overflow pipe 9 formed inside the water tank 6 makes it possible to evacuate an excess of water introduced into the water tank 6 towards the external waste water network 13, in particular by means of of said at least one valve 14 and the drain line 8. And the venting device 26 of the water tank 6 allows the evacuation of air when the water tank 6 is filled with water or the introduction of air during the water discharge of the water tank 6. This displacement of air inside the water tank 6 also serves to defuse the return of the washing water and / or rinsing stored in the water tank 6 to the washing tub 3, and vice versa, by allowing an introduction of air through said at least one through opening 42 formed in the first water circulation duct 10 arranged at the inside of the water tank 6. This defusing the return of the washing and / or rinsing water stored in the tank to see water 6 to the washing tub 3, and vice versa, can thus occur since said venting device 26 of the water reservoir 6 is in fluid communication with said at least one passage opening 42 of the first water circulation conduit 10 arranged inside the water tank 6. In the case where a surplus of water introduced into the water tank 6 can not be evacuated by the overflow pipe 9 arranged at inside the water tank 6, this excess water can be evacuated by the venting device 26 of the water tank 6 when the latter is connected to the zone 37 in fluid communication with the tank washing device 3 by means of the air flow tube 36. Preferably, the first water circulation pipe 10 is in fluid communication with a water circulation pump 12, in particular the second water circulation pump 12 of the water distribution circuit of the washing machine 1, mounted on the water tank 6 and located at a low point of the water tank 6.

Here and in no way limiting, the second water circulation pump 12 is fixed by screwing means on the wall 6b of the water tank 6. Advantageously, the second water circulation pump 12 and said at least - 27- a valve 14 are mounted on the water tank 6, and in particular on the wall 6b of the water tank 6. Thus, the washing machine 1 comprises the part of the hydraulic water distribution circuit necessary for operation of the latter without or with the water tank 6. The washing and / or rinsing water tank 6 can thus be installed on the washing machine 1 without modifying the hydraulic water distribution circuit internal to the washing machine 1. In one embodiment, the washing and / or rinsing water flows inside a single water circulation pipe 7 from the washing tub 3 to the reservoir of water. water 6, and vice versa.

Thus, the connection between the washing machine 1 and the water tank 6 is simplified and makes it possible to minimize the costs of obtaining the washing machine 1. Advantageously, the second part 7b of the second water circulation pipe 7 is formed inside the water tank 6, the second water circulation pipe 7 being on the one hand connected to said at least one valve 14 and on the other hand placed in fluid communication with the washing tank 3. In one embodiment, the water tank 6 comprises two shell-like walls 6a, 6b. A first shell 6a may constitute part of a wall of the bodywork 2 of the washing machine 1, in particular of the front wall 2a of the bodywork 2.

A second shell 6b is disposed inside the body 2 of the washing machine 1 and comprises the operating members of the water tank 6, such as the valve 14 and the water circulation pump 12, as well as the device for venting the water reservoir 6. The washing water storage and / or rinsing zone 6c of the water tank 6 is formed by assembling the two shells 6a, 6b of the water tank 6. The first water circulation pipe 10, the overflow pipe 9 and the second part 7b of the second water circulation pipe 7 are formed inside the water tank 6 and formed by assembling the two shells 6a, 6b of the water tank 6.

Fixing the two shell-shaped walls 6a, 6b of the water tank 6 can be made by welding. Of course, the method of fixing the two shell-shaped walls of the water tank is in no way limiting and may be different, in particular by screwing. We will now describe the operation of a washing machine according to an embodiment of the invention. The first water circulation pump 11 is adapted to drain at least a portion of the washing and / or rinsing water from the washing tub 3 to the water reservoir 6 by generating a flow of water. washing and / or rinsing water passing through said at least one valve 14 and the second water circulation pump 12 being inactive. Thus, the washing and / or rinsing water contained in the washing tub 3 of the washing machine 1 can be emptied into the water tank 6 so as to allow the reuse thereof during a phase following a running cycle or a subsequent operating cycle by storing the wash and / or rinsing water in the water tank 6. Draining the wash water and / or rinsing contained in the washing tub 3 of the washing machine 1 is effected by activating the first water circulation pump 11 installed in the washing machine 1, by opening an outlet opening of the valve 14 and maintaining stopping the second water circulation pump 12 so that a flow of water is circulated between the washing tub 3 of the washing machine 1 and the water tank 6. In this way, the washing and / or rinsing water can pass through the second water circulation pump 12 without opposing a resistance when the first The water circulation pump 11 is operated to drain wash and / or rinse water from the washing tub 3 of the washing machine 1 into the water tank 6. The washing and / or rinsing water can pass through the second water circulation pump 12 thanks to the internal clearances of this second water circulation pump 12 when the first water circulation pump 11 is put into operation. . And, the second water circulation pump 12 is adapted to drain at least a portion of the washing and / or rinsing water from the water tank 6 to the washing tank 3 by generating a flow of water. washing and / or rinsing water passing through the valve 14 and the first water circulation pump 11 being inactive. Thus, the washing and / or rinsing water contained in the water tank 6 can be emptied into the washing tub 3 of the washing machine 1 so as to reuse the latter during a subsequent phase of an operating cycle in progress or during a subsequent operating cycle following storage of the washing and / or rinsing water in the water tank 6. Draining the washing and / or rinsing water contained in the water tank 6 is effected by activating the second water circulation pump 12 installed in the water tank 6, by opening an outlet opening of the valve 14 and holding the first stop water circulation pump 11 so that a flow of water is circulated between the water tank 6 and the washing tub 3 of the washing machine 1. In this way, the washing water and / or rinsing can pass through the first water circulation pump 11 without opposing a resistance when the second circulation pump -29- water 12 is operated so as to drain the washing water and / or rinse contained in the water tank 6 inside the washing tub 3 of the washing machine 1. The water of washing and / or rinsing can pass through the first water circulation pump 11 thanks to the internal clearances of this first water circulation pump 11 when the second water circulation pump 12 is put into operation. In this embodiment, said at least one valve 14 is a single three-way valve for selecting the emptying of the washing tub 3 from the washing machine 1 to the water tank 6 or to the water network external discharge 13, or emptying the water tank 6 to the washing tub 3 of the washing machine 1 or to the external wastewater network 13, and discharging the excess water introduced into the storage tank. water 6 to the external waste network 13. The use of a valve 14 comprising three channels reduces the costs of obtaining the washing machine 1 equipped with a wash water tank and / or rinsing 6 and to simplify the management of the selection of the direction of the washing and / or rinsing water flows 6 in the hydraulic water distribution circuit of the washing machine 1. Of course, the use of a single valve for selecting the direction of the different streams of water is in no way limiting and this selection can be r erected by means of several valves. FIG. 2 illustrates a phase of emptying the washing tub 3 from the washing machine 1 to the external waste water network 13. This phase of emptying the washing tub 3 from the washing machine 1 to the washing network 1 external waste water 13 is effected by activating the first water circulation pump 11, by opening the valve 14 from the washing tub 3 of the washing machine 1 to the external waste water network 13 and putting into operation circulating the washing and / or rinsing water through the second water circulation pipe 7 and the drain line 8. The water tank 6 and the second water circulation pump 12 are not traversed by the flow of water for the emptying of the washing and / or rinsing water contained in the washing tub 3 of the washing machine 1 to the external waste water network 13. During this emptying phase from the washing tub 3 of the washing machine 1 to the external waste water network 13, the water tank 6 can be indifferently filled or empty.

In Figure 2, during the emptying phase of the washing tub 3 of the washing machine 1 to the external waste water network 13, the valve 14 is in an initial position where a flow of water flows. from the washing tub 3 of the washing machine 1 to the external waste water network 13 through said valve 14. The water flow enters through the water inlet / outlet opening 31 and exits through the water outlet opening 33 of the valve 14. During this phase of emptying the washing tub 3 from the washing machine 1 to the external waste water network 13, the actuators 27a, 27b of the valve 14 are not powered. Thus, the valves 28, 29, 30 of the valve 14 are not actuated and remain in the initial position. The valves 28, 29, 30 respectively seal the water flow passages 38a, 39, 40a. The water flow passages 38b, 40b are then opened to allow the flow of water to flow through the water flow passages 38b, 40b. In this way, the washing tub 3 of the washing machine 1 can be drained when the valve 14 is out of order. The washing machine 1 can thus be put into operation without using the water tank 6. FIG. 3 illustrates a phase of emptying the water tank 6 towards the external wastewater network 13. This phase of emptying the tank water 6 to the external wastewater network 13 is effected by activating the second water circulation pump 12, by opening the valve 14 from the water tank 6 to the external wastewater network 13 and by circulating the washing and / or rinsing water through the first water circulation pipe 10 and the drain line 8. The first water circulation pump 11 is not crossed by the water flow for draining the washing and / or rinsing water contained in the water tank 6 to the external wastewater network 13. This draining phase of the water tank 6 can be implemented either automatically or manually. The automatic emptying of the water tank 6 can be carried out periodically following the determination of the achievement of a predetermined duration of non-use of the washing machine 1 by a control unit of said washing machine 1.

In this way, the second water circulation pump 12 can be operated automatically to drain the wash water and / or rinse the water tank 6 to the external waste water network 13 by means of the control unit of the washing machine 1. The manual emptying of the water tank 6 can be implemented following the activation by the user of a drain control of the water tank 6 sent to the unit The user may wish to drain the washing water and / or rinse the water tank 6 to the external waste water network 13, in particular, in case of fear. a load of soiled linen, doubt about the washing water and / or rinsing collected, or for the movement of the washing machine 1. In Figure 3, during the emptying phase of the tank of water 6 to the external wastewater network 13, a stream of water flows from the water tank 6 to the external wastewater network 13 passing through the valve 14. The flow of water enters through the water inlet / outlet opening 32 and exits through the water outlet opening 33 of the valve 14. During this draining phase of the water tank 6 to the external waste water network 13, the actuator 27a of the valve 14 is not supplied with energy while the actuator 27b is supplied with energy. Thus, the valves 28, 29 of the valve 14 are not actuated while the valve 30 is actuated. The valves 28, 29, 30 respectively seal the water flow passages 38a, 39, 40b. The water flow passages 38b, 40a are then opened to allow the flow of water to flow through the water flow passages 38b, 40a. Referring to Figure 1, during emptying phase of the water tank 6, the introduction of air into the water tank 6 is provided by the venting device 43 of the washing tub 3 connected to the zone 37 of the washing tub 3, and by the venting device 26 of the water reservoir 6 connecting a zone 37 in fluid communication with the washing tub 3 to the water reservoir 6 through In this way, the water tank 6 fills with air as it is emptied of the washing and / or rinsing water. FIG. 4 illustrates a phase of emptying the washing tank 3 of the washing machine 1 towards the water tank 6 so as to recover the washing and / or rinsing water used during a phase of a operating cycle implemented by the washing machine 1. This phase of emptying the washing tub 3 of the washing machine 1 to the water tank 6 is effected by activating the first water circulation pump 11 by opening the valve 14 from the washing tub 3 of the washing machine 1 to the water tank 6, by circulating the washing and / or rinsing water through the second circulation pipe of water 7, of the first water circulation pipe 10 and crossing the second water circulation pump 12 being stopped. In Figure 4, during the emptying phase of the washing tub 3 of the washing machine 1 to the water tank 6, a stream of water flows from the washing tub 3 of the washing machine 1 to the water tank 6 through the valve 14. The flow of water enters through the water inlet / outlet opening 31 and exits through the water inlet / outlet opening 32 of the valve 14. -32- During this phase of emptying the washing tub 3 of the washing machine 1 to the water tank 6, the actuator 27b of the valve 14 is not supplied with energy while the actuator 27a is supplied with energy. Thus, the valves 28, 29 of the valve 14 are actuated while the valve 30 is not actuated. The valves 28, 30 respectively close the water flow passages 38b, 40a. The water flow passages 38a, 40b are then opened to allow the flow of water to flow through the water flow passages 38a, 40b. In this way, the water tank 6 fills with washing and / or rinsing water coming from the washing tub 3 of the washing machine 1 as the water tank 6 is emptied of water. air contained therein by the venting device 26 of the water tank 6. The air exiting from said at least one air passage opening 44 formed in a wall of the water tank 6 is discharged to the outside through the washing tub 3 of the washing machine 1. Here, the water tank 6 is emptied of its air contained therein, this flow of air through said at least one air passage opening 44 formed in a wall 6b of the water tank 6, then flowing through the air flow tube 36 opening into a zone 37 in fluid communication with the washing tub 3 of the washing machine 1. In this way, the air contained inside the water tank 6 is discharged through the air flow tube 36 until zone 37 in fluid communication with the washing tub 3 of the washing machine 1, then outside the washing tub 3 by a venting device 43 thereof.

Thus, a phenomenon of sound turbulence is avoided by sending the air contained in the water tank 6 to a zone 37 in fluid communication with the washing tub 3 of the washing machine 1 instead of sending the air into the external waste water network 13. The phenomenon of sound turbulence related to the sending of air contained inside the water tank 6 in the external wastewater network 13 is due to the installation of the drain line 8 generally comprising a bend 45 causing stagnation of water at this point. When filling the washing water and / or rinsing water tank 6, the air escaping from the water tank 6 to the external waste water network 13 through the drain line 8 is blocked by stagnant water in the bend 45 of the drain line 8, and causes a sound turbulence amplified by the rest of the drain line 8. This phenomenon of sound turbulence is unpleasant for the user and that -33- it can be considered as a failure. The connection of the water reservoir 6 to the zone 37 in fluid communication with the washing tank 3 of the washing machine 1 through the air flow tube 36 allows the air contained inside to be evacuated. of the water tank 6 to the outside so as to eliminate the phenomenon of sound turbulence related to the air supply in the external wastewater network 13. A surplus of washing water and / or rinsing fed in the water tank 6 is discharged automatically through the overflow line 9 to the valve 14 and then to the drain line 8 to the external waste water network 13.

In FIG. 4, when an excess of washing and / or rinsing water is fed into the water tank 6 during the emptying phase of the washing tank 3 of the washing machine 1 towards the tank 6, a stream of water flows from the overflow line 9 of the water tank 6 to the external waste water network 13 through the valve 14 and the drain line 8. The flow of water water enters the water inlet opening 17 of the overflow pipe 9, then through the water inlet opening 41 of the valve 14 and exits through the water outlet opening 33 of the valve 14. During this phase of emptying the washing tub 3 from the washing machine 1 to the water tank 6, the valve 28 closes the water flow passage 38b so that the flow water supplying washing water and / or rinsing the water tank 6 from the washing tank 3 and the flow of water flowing from the overflow line 9 of the water tank 6 to the network external waste water 1 3 be separated. The water flow passages 38a, 40b are then opened to allow the flow of water to flow through the water flow passages 38a, 40b so as to supply washing and / or rinsing water on the water flow passages 38a, 40b. water tank 6 from the washing tub 3. And the water flow passage 39 is open to allow the flow of water to flow through the water flow passage 39 so as to evacuate the excess water introduced into the water tank 6 to the external wastewater network 13. A small amount of washing and / or rinsing water can pass through the venting device 26 of the storage tank. 6 when the overflow pipe 9 is full and the flow of water entering the water tank 6 is greater than the flow rate of water flowing in the overflow pipe 9. In particular, a low amount of washing and / or rinsing water can pass through the air flow tube 36 and return to the washing tub 3 of the a washing machine 1 without causing any incident neither for the operation of the washing machine 1 nor for the laundry which can be placed in the drum enclosed in said washing tub 3. FIG. 5 illustrates a phase of emptying the reservoir of water 6 to the washing tub 3 of the washing machine 1 so as to reuse the washing and / or rinsing water used during a phase of an operating cycle carried out by the washing machine. washing 1 and stored in the water tank 6. This emptying phase of the water tank 6 to the washing tub 3 of the washing machine 1 is effected by activating the second water circulation pump 12, in opening the valve 14 from the water tank 6 to the washing tub 3 of the washing machine 1, by circulating the washing and / or rinsing water through the first and second water circulation pipes 10, 7 and crossing the first water circulation pump 11 being stopped. During the phases of emptying the washing water and / or rinsing the washing tub 3 from the washing machine 1 to the water tank 6, and vice versa, these are hydraulically coupled by the valve 14. In FIG. 5, during the emptying phase of the water tank 6 towards the washing tub 3 of the washing machine 1, a stream of water flows from the water tank 6 to the washing tub 3 of the washing machine 1 passing through the valve 14. The flow of water enters through the water inlet / outlet opening 32 and exits through the water inlet / outlet opening 31 of the valve 14 During this phase of emptying the water tank 6 to the washing tank 3 of the washing machine 1, the actuator 27b of the valve 14 is not energized while the actuator 27a is energized. in energy.

Thus, the valves 28, 29 of the valve 14 are actuated while the valve 30 is not actuated. The valves 28, 30 respectively close the water flow passages 38b, 40a. The water flow passages 38a, 40b are then opened to allow the flow of water to flow through the water flow passages 38a, 40b.

In this way, the water tank 6 fills with air by the venting device 26 of the water tank 6 as it is emptied of the washing water and / or rinsing contained inside the water tank 6 to the washing tub 3 of the washing machine 1. The air entering through said at least one air passage opening 44 formed in a wall 6b of the water tank water 6 is sucked from the outside through the washing tub 3 of the washing machine 1. Here, the water tank 6 is filled with air from the washing tub 3 of the washing machine. washing 1, this flow of air flowing through the air flow tube 36, passing through said at least one air passage opening 44 formed in a wall 6b of the water tank 6, and opening into the reservoir 6. In this way, the introduction of air into the water tank 6 is ensured by the suction of air through a vent device 43 of the tank of water. washing 3, a zone 37 in fluid communication with the washing tank 3, then in the air flow tube 36 to the water tank 6. The two valves 28, 29 can be connected by a connecting rod 18 so as to allow simultaneous opening and closing of the water flow passages 38a, 38b, 39. These two valves 28, 29 operate simultaneously in opening and closing. Therefore, a single actuator 27a associated with a rod 18 is necessary to allow the displacement of these valves 28, 29 so as to minimize the costs of obtaining the valve 14 and simplify the management of the latter by the control unit. washing machine control 1. The valve 28 of the valve 14 is in the open position each time the water tank 6 is in hydraulic communication with the washing tub 3 of the washing machine 1. The volume of air and water varies in the water tank 6 with each transfer of water between them.

The valve 29 of the valve 14 also passes into the open position when the water tank 6 is filled with water from the washing tank 3 of the washing machine 1 so that a surplus of water is introduced into the tank of the water 6 is evacuated by the overflow pipe 9, then through the valve 14, and in particular by the water flow passage 39, and then into the drain pipe 8 to the water network 13. In this way, if the amount of wash water and / or rinse from the washing tub 3 of the washing machine 1 is too large and can not enter the water tank 6, then the passage of water flow 39 of the valve 14 disengaged by the opening of the valve 29 makes it possible to send the excess washing and / or rinsing water to the external wastewater network 13 of the machine. 1. In addition, the valve 29 of the valve 14 is closed in the case of the emptying of the washing water and / or rinsing the washing tank 3 of the washing machine 1 or water tank 6 to the external waste water network 13 so as to prevent washing and / or rinsing water from being introduced into the water tank 6 while going up in the pipe 9. These two valves 28, 29 can thus be physically connected to each other by a rod 18 and be actuated simultaneously by a single actuator 27a. The washing machine 1 comprises a control unit, in particular a microcontroller, making it possible to implement cycles of operation thereof.

The control unit of the washing machine 1 controls the filling and emptying of wash water and / or rinsing of the water tank 6 by means of the first and second water circulation pumps 11, 12 and at least one valve 14. The control unit of the washing machine 1 can supply water to the washing tub 3 with water from the external water network and / or with washing and / or rinsing water from the water tank 6.

The water supply of the washing tub 3 of the washing machine 1 is carried out with water from the external water network and / or with washing and / or rinsing water from the water tank. water 6 in particular, the phases of the operating cycle implemented by the washing machine 1, the amount of water contained in the water tank 6.

Of course, the parameters defining the source of the water supply of the washing tub are in no way limiting and may be different. The control unit of the washing machine 1 also makes it possible to drain the washing tub 3 and / or the water tank 6 towards the external waste water network 13 as a function, in particular, of the phases of the operating cycle set. implemented by the washing machine 1, the amount of water contained in the water tank 6, the level of soiling of the water. Of course, the parameters defining the decision to empty the water contained in the washing tub and / or in the water tank to the external wastewater network are in no way limiting and may be different.

The control unit of the washing machine 1 is adapted to manage the water flow transfers in the hydraulic water distribution circuit of the washing machine 1. Thanks to the present invention, said at least one element of deviation of a stream of water disposed inside the water tank prevents a projection of water on the upper surface of the amount of water present inside the water tank during the water filling phase of the water tank. In this way, the noise generated by the water inlet during the water filling of the water tank is minimized. Of course, many modifications can be made to the embodiments described above without departing from the scope of the invention.

Thus, the washing and / or rinsing water tank associated with the washing machine could be used in other household appliances, for example a dishwashing machine or a washing and drying machine.
