-1 "Bin intended for household cleaning, and assembly comprising such a bin and a broom"

The present invention relates to a cleaning tank intended for household cleaning of any type of smooth surface, in particular of floors.

The present invention also relates to an assembly comprising such a tray and a brush.

State of the art

In the field of household cleaning, it is known to use a bucket filled with a cleaning liquid, for example water mixed if necessary with a cleaning product or detergent. In general, the user soaks a mop in the cleaning liquid before applying it to the floor to scrub the floor with said mop. Then the mop is again soaked in the liquid contained in the bucket to be rinsed and then wrung before being soaked again to clean a new portion of soil. The user repeats the operation as many times as necessary to clean the desired floor surface. However, these operations result in contaminating the cleaning liquid as and when with the dirt removed from the soil to be cleaned. This results in frequent replacement of the cleaning liquid and overconsumption of water and cleaning product. Multi-compartmentalized buckets were then proposed, comprising a tank of cleaning liquid and a vase of dirty water, the latter surmounted by a wringing device. However, these devices do not prevent contamination of the reservoir of clean liquid because the dirt is always present on the mop so that a portion nevertheless dilutes in the reservoir of clean liquid when the mop is immersed in the reservoir in order to be rinsed or soaked to clean a new portion of soil.

Document EP0781524 discloses a metering device which aims to limit the consumption of cleaning liquid. The metering device comprises a reserve chamber containing the cleaning liquid and a wetting chamber in which a cleaning tool is immersed in the cleaning liquid. The cleaning liquid is introduced in a controlled manner via a metering valve and an actuator

-2 acting on said valve, from the reserve chamber to the wetting chamber.

However, it is difficult to assess the quantity of liquid entering the wetting chamber so that consumption is still excessive and / or the adjustment of the water level not easy. In addition, the brush is spun in the wetting chamber so that the cleaning liquid is also contaminated.

The object of the invention is to propose a cleaning device reducing the consumption of water and the consumption of cleaning product. It also aims to avoid or at least reduce the contamination of the cleaning liquid each time the broom is immersed in the device after use on a floor, improving hygiene. It also aims to facilitate the use of a cleaning device. It aims to offer a more economical and more ecological device. Finally, it aims to offer a more reliable and more compact cleaning device.

Statement of the invention

At least one of the objectives is achieved with a tank intended for household cleaning, with a cleaning liquid. The tank is intended to contain at least one cleaning liquid. Household cleaning means the cleaning of floors or living surfaces or the cleaning of floors or surfaces for professional use. The term “cleaning liquid” typically means water, mixed if necessary with one or more detergent and / or cleaning products.

The tray includes:

- a tank of cleaning liquid,

a basin, arranged so that a spongy body can collect said liquid by absorption when the tank is in the cleaning position, for example the tank being placed flat on the floor,

- a partition separating the cleaning liquid tank and the basin,

- At least one opening arranged in the partition, providing a passage for the cleaning liquid to the basin.

According to the invention:

-3- the at least one opening is close to the bottom of the tank and distant from an upper wall of the cleaning liquid tank, so that a capacity of the basin, when the opening is just submerged by the cleaning liquid, is much lower than the maximum capacity of the tank,

- the at least one opening ensures permanent communication between the reservoir and the basin, and

- the cleaning liquid tank is airtight when the at least one opening is submerged in cleaning liquid.

The invention is based on Pascal's principle which characterizes the balance of liquids. Applied to the cleaning tank, the cleaning liquid (of uniform density) is in balance between the tank of cleaning liquid and the basin. The surface of the cleaning liquid contained in the tank is always subjected to atmospheric pressure, while the surface of the cleaning liquid contained in the tank is subjected to a lower pressure due to the airtightness of the tank. After a sampling in the basin by a spongy body, the at least one opening is not submerged on the basin side, it allows an entry of air into the tank and consequently the cleaning liquid contained in the tank flows into the basin, until the liquid level in the basin closes the opening again. According to the invention, the level of cleaning liquid is substantially constant in the basin while it decreases regularly in the tank, as the tank replenishes the basin after each withdrawal from the basin. Thus, the liquid always moves from the reservoir to the basin, so that any dirt brought back by the spongy body does not contaminate the reservoir, which therefore always supplies the basin with perfectly clean liquid. The permanent communication between the basin and the reservoir is a guarantee of reliability, compared to the prior art. Furthermore for this, unlike the prior art, it is not necessary to actuate a device which greatly facilitates and secures use. Preferably, the content of cleaning liquid of the pelvis corresponds to an amount just sufficient to suitably soak the spongy body. Overconsumption of cleaning liquid is also controlled or avoided, as is the risk that

-4 residual dirt, after spinning, mix with a large amount of liquid, which improves hygiene during cleaning.

Preferably, the cleaning tank has a generally rectangular external shape. The pelvis has an overall interior shape that is substantially rectangular or quadrilateral so that the spongy body can rest on the surface of the bottom of the pelvis.

The cleaning tank according to the invention is intended to be used, typically, with a broom comprising a spongy body on or around the head of the broom.

For example, the brush includes a head of substantially rectangular or quadrilateral shape so that said head is surrounded at least in part by the spongy body. In this case, the spongy body is a mop or wipe. The shape of the head of the broom is dimensioned so that the head can rest on the surface of the bottom of the basin in a kind of nesting in the basin.

According to another example, the brush includes a head of substantially cylindrical shape on which are arranged fringes constituting the spongy body. This type of broom is called a mop. Preferably, the length of the fringes is chosen so that they can all fit into the pelvis.

According to yet another example, the cleaning container is also intended to be used with a sponge, a wipe or one of the devices, provided with a spongy body, mentioned above and provided with a handle so that the container is also easy to be used for cleaning table or glass surfaces.

Preferably, the cleaning liquid tank and the basin are juxtaposed. The bottom of the cleaning liquid tank is at the same level as the bottom of the basin so that the cleaning liquid flows freely from the tank to the basin. According to the preferred embodiment, the bottom of the cleaning liquid tank and the bottom of the basin are made in one piece, constituting a bottom wall of the cleaning tank.

-5According to another embodiment, the tank of cleaning liquid can partly be located above the basin, for example separated by several centimeters. A main tank of cleaning liquid is connected to an intermediate tank, of very small capacity compared to the main tank, via a pipe. The intermediate tank is separated from the basin by the partition having the at least one opening. The partition having the at least one opening may have any geometric shape, for example rectangular, polygonal, cylindrical or conical and be inclined at a non-zero angle relative to the bottom of the basin.

The at least one opening constitutes a tunnel between the reservoir of cleaning liquid and the basin. The at least one opening is permanently open. The term “permanently open” means an opening or free passage of any part, or set of parts linked together, passing through the opening and projecting on either side of the partition, said part or set of parts. extending in a direction normal to the plane in which the at least one opening is formed and being arranged (s) and configured (s) to obstruct said opening. For example, the term "permanently open" means an unobstructed opening of the valve type. During use, that is to say in the cleaning position, the cleaning liquid reservoir is airtight when the at least one opening is submerged in cleaning liquid. For example, the partition is inclined angularly at an angle between 45 and 90 degrees relative to the horizontal.

For filling the cleaning liquid tank, the at least one opening is arranged and configured to produce an air intake for the cleaning liquid tank when the tank is tilted properly in relation to the cleaning position, in the direction placing the at least one opening in the high position. In practice, the reservoir is filled with cleaning liquid by pouring cleaning liquid into the basin, then by tilting the tank so that the liquid flows into the tank via the at least one opening. For example, the bin is angularly inclined about 30 degrees from the horizontal. According to other embodiments the tank can be tilted at an angle between 1 and 90 degrees relative to

-6horizontal. The cleaning tank can be gradually tilted in order to produce a continuous air intake, via the at least one opening, to fill the tank as much as possible. The inclination allows the air present in the cleaning liquid tank to escape during filling. To completely fill the tank, the tank is tilted so that the surface of the cleaning liquid reaches the level of the at least one opening. When the tank is rotated in the opposite direction to the cleaning position, the cleaning liquid flows into the basin, through the at least one opening, until the at least submerged an opening. At the same time, an air pocket of pressure below atmospheric pressure has been created between the upper wall of the tank, constituting the ceiling of said tank, and the surface of cleaning liquid in the tank. The balance of the cleaning liquid between the basin and the reservoir is then achieved. According to another embodiment, an additional air intake is produced on one face of the basin, separating the reservoir of cleaning liquid and the basin, to facilitate filling of the reservoir of cleaning liquid, this air intake being submerged in position cleaning or closable by a plug or a valve.

According to the invention, the height of the at least one opening corresponds substantially to the height of the level of cleaning liquid in the basin. The level of cleaning liquid in the basin corresponds substantially to the level necessary to submerge the at least one opening. According to one embodiment, the height of the at least one opening is preferably between 1 and 15 millimeter (s) relative to the bottom of the basin, in particular between 3 and 5 millimeters. This embodiment of the tank is preferred for use with a mop head provided with a wipe. According to another embodiment, the height of the at least one opening is preferably between 10 and 15 millimeters. This embodiment of the tray is preferred for use with a mop head provided with fringes. The height of the at least one opening can be up to 20 millimeters. This height of liquid in the basin allows the spongy body surrounding the broom to be soaked enough to allow the cleaning of the floor and saves the cleaning liquid, generally water and / or detergent product (s) or cleaner (s).

In this way, contamination of the liquid present in the basin is also avoided because the head of the brush is not immersed, the liquid permeating the brush by capillary action.

Several openings aligned and spaced a few centimeters apart can be arranged in said partition.

Optionally, the bottom of the tank can be hollowed out, forming a cavity, from one to several millimeter (s) deep below each opening. The cavities make it possible to increase the section of passage of the cleaning liquid of the openings when filling the tank of cleaning liquid. This characteristic makes it easier to fill the tank with cleaning liquid, in particular when the height of the opening is small. The creation of the cavities does not modify the height of the level of the cleaning liquid in the basin.

The cleaning tank preferably includes a chamber for collecting used liquid. The collection chamber makes it possible to receive the used liquid present in the spongy body of the broom before humidifying it again in the basin. The used liquid collection chamber and the cleaning liquid tank are separated by a single wall. This feature makes it possible to offer a compact cleaning container.

Preferably, the cleaning liquid reservoir comprises a zone of reduced section forming a passage for the cleaning liquid between the cleaning liquid reservoir and the basin. The passage is located near a side opposite an exit from the collection chamber. According to one embodiment, said passage communicates with the at least one opening arranged in the partition separating the basin from the tank of cleaning liquid, said partition extending in a direction transverse to the tank.

Preferably, the tank comprises a cavity, forming an anti-chamber, located between the reservoir of cleaning liquid and the basin. The cavity is formed between the partition having at least one opening and a retention partition extending in the direction of a first longitudinal side of the tank but leaving a passage, corresponding to the section area

-8reduced, between the end of the retention partition and the inside of the first longitudinal side. The outlet from the collection chamber is provided through a second longitudinal side of the tank which is opposite to the first longitudinal side. In this way, the tank can be tilted towards the second longitudinal side which places the passage in the high position and makes it possible to empty the used liquid collection chamber while preventing the leakage or spillage of the cleaning liquid contained in the tank thanks to the retention partition. This also allows the pool water to return quickly to the tank when the tank is tilted in an upright position, so that the pool is located above the cleaning liquid tank in the vertical position.

The tank preferably comprises a wringing area having at least one scraper, arranged and configured to allow the spongy body, for example the spongy body surrounding the brush, to be rubbed therein. The wringing area allows the evacuation of the used liquid soaking the spongy body. Preferably, the wringing area includes ribs. For example, the ribs can be arranged in a V shape.

According to another embodiment, the wringing zone has the shape of a cylinder projecting from the upper face of the cleaning tank, when the latter is in the cleaning position. The wringing area includes a cone-shaped cavity arranged in the cylinder, the cone widening upwards. The surface of the cone has ribs, arranged and configured to allow it to rub a spongy body of the type comprising fringes, for example a mop. The mop is preferably wrung on the wringing area by applying the head of the mop with the fringes against the ribs and turning the mop so that the fringes rub against the ribs.

The wringing zone communicates with the used liquid collection chamber. Preferably, the wringing zone is situated on an inclined plane so that the used liquid flows by gravity into the collection chamber. For example, the used liquid flows by gravity into a cavity, constituting the collection chamber, juxtaposed with the wringing zone. The cavity is fully open on the top.

According to one embodiment, the collection chamber is located below the wringing area so that the collection chamber is partially covered on top. The upper wall of the tank corresponds to a separation between the wringing zone and the collection chamber; the upper surface of said wall constituting the wringing area, and the lower surface of said wall the ceiling of the collection chamber when the tank is in the cleaning position. The upper wall has an outlet for discharging the used liquid. The evacuation orifice is arranged and configured so that the used liquid present on the wringing zone flows by gravity towards the collection chamber. The upper wall of the tank is substantially concave and inclined so that the water flows by gravity towards the discharge orifice.

According to the preferred embodiment, the wringing zone is located both above the collection chamber and the tank of cleaning liquid. This feature makes it possible to offer a compact cleaning container.

Preferably, the tank comprises a device for adjusting the height of the at least one opening in order to adjust the level of cleaning liquid in the basin. According to a particular embodiment, the adjustment device is a plate extending longitudinally, forming a strip, arranged parallel to the partition. The strip is arranged and configured to translate in height and parallel to the partition. For example, the transverse partition has, on one of its faces, a device for guiding the strip, such as grooves, for guiding the translation of the strip. Optionally, the strip includes a sealing lip arranged and configured to bear on the face of the partition in order to allow the height of the at least one opening to be adjusted. This characteristic makes it possible to vary the height of the at least one opening from 1 to 20 millimeter (s). This characteristic makes it possible to enlarge the section of the at least one opening and makes it easier to fill the tank with cleaning liquid.

Optionally, the container comprises a vase for household cleaning product or detergent, arranged and configured to diffuse

-10cleaning or detergent product in the basin. The vase is placed between the cleaning liquid tank and the basin. Preferably, the vase is placed on a side wall of the basin but without touching the bottom of the basin. For example, the vase comprises, at its base, orifices of very small sections arranged on the bottom or on a lateral face near the bottom thereof, so as to diffuse the cleaning product in the basin. This allows the tank to be filled with water, which adds cleaning product when it is in the basin. Preferably, said vase is removable to facilitate its filling. For example, the cleaning product is solid and diffuses by erosion when the user introduces water into the vase.

According to a particular embodiment, the tank is arranged and configured to be placed on the ground in an upright position in which the basin is located above the tank of cleaning liquid and the at least one opening is in the high position relative to to the cleaning liquid tank. For example, the upright position corresponds to a substantially vertical position. During this vertical positioning, it is expected that the water contained in the basin returns to the tank, and that the used liquid contained in the collection chamber cannot escape. According to a particular embodiment, the outlet of the collection chamber and the discharge orifice are positioned in the upper part of the collection chamber when the tank is in a substantially vertical position. The outlet of the collection chamber and the discharge orifice are positioned relative to the tank to prevent the used liquid from escaping when the tank is in a substantially vertical position. In this position, neither the cleaning liquid contained in the tank, nor the used liquid contained in the collection chamber can spill. This feature allows the user to be able to raise the tray, transport it vertically to another room, then place it horizontally on the floor to clean this other room. During this horizontal reset of the tank on the ground, the cleaning liquid contained in the tank returns to the basin, and the used liquid contained in the collection chamber returns to horizontal without being able to escape. For example, the container has on its periphery an oblique transverse face which constitutes the lower face in the upright position. In this way, the bin automatically switches to rest against a

-11 vertical wall such as a wall when the tank is placed on the ground in an upright position along this wall. This feature makes it easier to store the cleaning container.

Preferably, the container comprises a hooking device near the basin. Said attachment device is arranged and configured to allow the tank to be suspended without the reservoir or the collecting chamber of the used liquid being able to empty. This feature makes it easier to store the cleaning container. According to a particular embodiment, the attachment device is arranged and configured to cooperate with at least one hook fixed on the handle of a broom so that the bin can be stored while being suspended by means of the broom. -Even suspended or placed on the ground, or the bin being placed vertically on the ground and against a wall with the broom engaged by the hook. In addition this allows the bin to be raised using the broom without the user needing to bend down.

According to a preferred embodiment, the tray is made in one piece so that it forms a single piece. Such a cleaning tank is compact. In this embodiment, the tank comprises at least the cleaning liquid reservoir, the basin, the transverse partition comprising the at least one opening, and if necessary the used liquid collection chamber and / or the wringing zone. having at least one scraper. If provided, the retention wall can also be made in one piece with the tank. Preferably, the tank is manufactured by an extrusion blow-molding method. Certain elements can however be added to the “single” part, for example the detergent vase, for example by snap sliding.

According to another embodiment, the cleaning liquid tank is removable. This feature makes it easier to fill the tank. In this embodiment, the cleaning liquid pours into the bottom of the tank.

Optionally, the tray includes non-slip pads arranged under the bottom of the tray. The non-slip pads are arranged and

-12configured to limit slippage between the tank and the floor when the tank is in the cleaning position, especially when scraping the spongy body onto the wringing area. Optionally, a space can be provided on the tray for the user's foot, so that he can press the tray on the ground in order to limit the sliding between the tray and the floor when the tray is in cleaning position, especially when scraping the spongy body onto the wringing area.

Whatever the embodiment, the cleaning liquid reservoir preferably has a capacity of at least 1 liter. According to other particular embodiments, the cleaning liquid tank can contain up to 5 liters of cleaning liquid. The used liquid collection chamber can also be removable, in particular to facilitate emptying.

According to another aspect of the invention which is compatible with the first, an assembly is provided comprising a container, intended for household cleaning according to one or more of the preceding characteristics, and a brush arranged and configured to cooperate with said container. Preferably, the tray and the brush each comprise a hooking device arranged and configured to put the tray and the brush simultaneously in the storage position. Preferably, the tray comprises a hooking bar such as an eyelet arranged and configured to cooperate with a device for hooking the brush. Preferably, the brush includes at least one hook arranged and configured to cooperate with the hanging bar or the eyelet of the cleaning tank. Even more preferably, the assembly includes a brush whose head has a contour which fits with little play in the interior contour of the basin. The set may also include a mop.

Description of the embodiments

The embodiments which will be described are in no way limiting; it will be possible in particular to implement variants of the invention comprising only a selection of characteristics described subsequently isolated from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention from in the prior art. This selection includes at least one preference characteristic

Functional without structural details, or with only part of the structural details if this part only is sufficient to confer a technical advantage or to differentiate the invention from the state of the prior art.

In particular, all the variants and all the embodiments described can be combined with one another if there is nothing technically opposed to this combination.

FIG. 1 illustrates a cleaning tank 1 intended to receive cleaning liquid in particular for cleaning floors of the smooth type, for example tiles or parquet. During the cleaning operation, the tank is used with a broom 100 comprising a handle 102 and a head 101 furnished with a spongy body 104, said spongy body being provided for absorbing the cleaning liquid from the cleaning tank and then being applied to the floor to be cleaned. The head 101 is connected to the handle 102 by a joint 108.

With reference to Figures 1 to 3, 4a, 4c, 4d, 4th, 6a, 7, 9a and 9b the tank 1 comprises a reservoir 2 (visible in Figure 1 by a cutaway) arranged and configured to receive and store cleaning liquid L. The cleaning liquid L can be a mixture of tap water and cleaning product and / or detergent for floors, or simply tap water.

The tank 1 comprises a basin 3, entirely open on the top, arranged to contain cleaning liquid L. The basin 3 is arranged so that the head 101 of the brush 100 covered with the spongy body 104 can collect said liquid by absorption when the tank is in a cleaning position where the bottom of the tank and the basin are substantially horizontal. According to the preferred embodiment, the bin is intended to be used with a so-called "broom-mop" broom. Generally, the head of a "mop broom" comprises at least one surface, intended for application on the ground, having a polygonal shape, in particular quadrangular. The internal contour of the basin is provided to correspond to the external shape of the head 101 of the brush 100, so that the head 101 fits with little play in the basin 3. This characteristic makes it possible to wet the entire application surface of the head of the broom while limiting the size of the basin to what is strictly necessary. Thus the tank is more compact and the head 101 absorbs almost all of the liquid present in the basin when it is immersed in the basin,

-16 avoiding to soil the cleaning liquid which could remain in the basin. According to another embodiment shown in Figures 5, 6a to 6d, the basin can be round or oblong in the case of mop.

According to the embodiments shown, the basin 3 is juxtaposed with the tank 2 of the cleaning liquid L. The tank 1 comprises a partition 4 separating the tank 2 of cleaning liquid and the tank 3. The tank 1 comprises at least one opening 5 arranged in the partition 4 for supplying the basin 3 with cleaning liquid L. Preferably, the tank comprises several openings, for example from 2 to 10, preferably 5 or 6 openings, to supply the basin 3 with cleaning liquid more quickly. With reference to FIGS. 1, la, 4a, 4c, 4d, 4e, 5, 6a, 6c, 9a and 9b, the openings 5 are close to the bottom lf of the tank and opposite to an upper part ls of the tank 2. Unlike the 'prior art, the opening or openings provide permanent communication between the tank and the basin. Surprisingly, the cleaning liquid can flow from the reservoir 2 to the basin 3 in a controlled manner without encountering any obstruction of an actuating device of the valve type. This characteristic allows the user not to worry about the distribution of the cleaning liquid towards the basin. The tray is thus easier to use. When the at least one opening 5 is submerged in cleaning liquid L as shown for example by FIGS. 4a, 4c, 4d, 6a, 9a and 9b, the tank 2 is airtight. This implies that no other additional opening, for example on the upper part ls of the tank 2, is left free. Controlled distribution is carried out thanks to the Pascal principle which characterizes the balance of liquids. The at least one opening 5 allows the cleaning liquid L contained in the tank 2 to flow in a controlled manner into the basin 3 while the return of air to the tank also takes place through the opening 5, until the liquid level in the basin 3 closes the at least one opening 5 and prevents the return of air. The transfer of cleaning liquid L is then interrupted because the tank 2 is under vacuum for lack of air intake. When the level of cleaning liquid in the basin decreases, the air intake is restored and flow resumes. This arrangement makes it possible to obtain a constant level of cleaning liquid L in the basin 3. According to the preferred embodiment, the height of the opening (s) is chosen so that

That the capacity of the basin is much lower than the maximum capacity of the tank 2. The capacity of the basin 3 is chosen so that the volume of liquid present can be absorbed by the spongy body. With reference to FIGS. 4a, 4c and 4d, the height of the at least one opening corresponds substantially to the height of the level of cleaning liquid in the basin 3. Preferably, the height of the at least one opening is between 1 and 15 millimeter (s). In the case of a mop head comprising a wipe, the preferred height of the at least one opening is between 3 and 5 millimeters. In the case of a mop head comprising fringes, the preferred height of the at least one opening is between 10 and 15 millimeters. In each case, the capacity is appropriate to properly soak the spongy body, without excess. The consumption of tap water and detergent or cleaning product is also limited. Thanks to the relatively small amount of liquid, the flow of liquid very largely goes from the basin to the spongy body by capillary action, limiting the risks that dirt from the broom migrates into the basin. When the user wishes to clean the sponge body of the broom, he immerses it in the basin 3 then scrapes the sponge body on the wringing zone, this as many times as necessary to remove the dirt from the sponge body and without dirtying the water of the pelvis.

According to another particular embodiment of the container and with reference to FIG. 1b, the bottom of the container has a cavity 5c arranged perpendicular to each opening. This characteristic makes it possible to increase the passage surface during filling of the reservoir without this modifying the height of the at least one opening 5 and therefore the height of the level of cleaning liquid in the basin 3.

According to a particular embodiment and with reference to FIGS. 9a and 9b, the tank 1 comprises a device 20 for adjusting the height of the opening (s) 5, in particular a plate 20, such as a strip, of substantially rectangular shape , translatable from bottom to top and / or vice versa along the partition 4. With reference to FIGS. 9a and 9b, the adjustment device 20 has been actuated upwards from its position represented by FIG. 9a to its position represented by the Figure 9b. The adjustment device allows you to adjust the level of cleaning liquid in the

-18 basin 3, for example depending on the thickness or type of spongy body placed on the head of the broom.

Or the opening (s) 5 is (are) arranged (s) and configured (s) to produce an air intake for the tank 2 and allow it to be filled with cleaning liquid. Referring to Figure 2, the tray 1 is inclined so that the basin 3 is located above the tank 2. According to the example shown in Figure 2, the tray is inclined at an angle of about 30 degrees with respect to a horizontal plane. The inclination of the tank allows the cleaning liquid L to enter the tank 2 through the opening (s) 5 and ensure the passage of air via the opening (s) 5 between the tank 2 and outside (see Figures 2 and 3). According to other embodiments not shown, the tray is pivoted angularly from a horizontal plane to a substantially vertical plane.

According to a particular embodiment represented in FIG. 3, the tank 1 comprises an internal retention partition 6 arranged behind the partition 4. The partition 6 extends inside the container from a longitudinal side, forming a non-zero angle , preferably a few degrees, for example about 10 degrees, relative to the partition 4 and ends a few centimeters from the other longitudinal side of the tank, for example 5 centimeters. The space left free corresponds to a zone of reduced section defining a passage 13. The space formed between the partition 4 and the internal partition 6 defines a cavity or an anteroom 7. When filling the reservoir 2, the cleaning liquid L flows in particular along the internal partition 6 and is introduced into the tank 2 via the passage 13 along the route indicated by the arrow 14.

According to Figures 1, 2, 3, 4a, 4c, 4d, 4th, 6a, 6b and 7, the tank includes a collection chamber 8 (visible through a cutaway from its upper wall in Figure 1) for the used liquid U. According to the preferred embodiment and with reference to FIGS. 1, 3 and 7, the collection chamber 8 is adjacent to both the reservoir 2 and to the basin 3. According to another embodiment and with reference to FIGS. 2, 4a, 4c, 4d, 4e, the collection chamber 8 is only adjacent to the reservoir 2 of cleaning liquid L on the side opposite to the basin 3. Preferably, and with reference to FIGS. 3 and 7, the collection chamber 8 and the reservoir 2 are separated by

-19 only one partition 15. These characteristics make it possible to offer a compact bin. Depending on the method of manufacturing the tank used, for example of the blowing type, it may be necessary to make a double partition between the tank 2 and the collection chamber 8. The collection chamber allows the used liquid to be received after the user has wrung out the spongy body. With reference to FIGS. 3 and 7, the tank 1 comprises an outlet 9 from the collection chamber 8 to allow said chamber to be emptied (see FIG. 7). According to the embodiment shown, the outlet 9 is located on a longitudinal side which is opposite to the passage 13. This characteristic, associated with the retention partition 6 and with the partition of separation between the reservoir 2 of cleaning liquid and the collection, used to drain the used liquid by tilting the tank to the longitudinal side equipped with the outlet 9 without the cleaning liquid L remaining in the tank 2 can escape.

With reference to FIGS. 1, 2, 4a to 6d, the tank 1 comprises a wringing area 10 in order to evacuate the used liquid U present in the spongy body after having rubbed the ground with the brush. The wringing zone 10 has scrapers or ribs 11 arranged and configured to be able to rub the spongy body surrounding the head of the broom. According to the preferred embodiment and with reference to FIG. 1, the wiping zone 10 forms the upper wall of the tank 2 and of the collection chamber 8. According to the embodiment shown in FIGS. 5 to 6d, the zone d 'spinning has the shape of a cone flaring upward and arranged and configured to receive the fringes of a mop. The wringing zone 10 communicates with the collecting chamber 8 so that the used liquid extracted from the spongy body by the wringing operation flows into the collecting chamber 8. With reference to FIGS. 2, 4a, 4c, 4d and 4e, the used liquid U flows along the surface of the wringing zone 10 before falling into the collection chamber 8. The surface of the wringing zone is preferably slightly inclined to favor the flow towards the collection chamber. Referring to Figure 3, the used liquid U flows into the collection chamber 8 passing through an orifice 12. The orifice 12 is arranged on the surface of the wringing zone. According to the embodiment of Figure 5, the used liquid flows through an orifice (not

-20represented) at the bottom of the cone. According to the embodiment shown in Figures 6a to 6d, the used liquid flows via a substantially vertical notch, of small width relative to the perimeter of the cone, produced in the cone.

Optionally and with reference to FIGS. 8a and 8b, the container comprises a vase 30 for a household product. In this case, the tank 2 contains tap water. The vase 30 is placed between the reservoir 2 and the basin 3. The vase 30 comprises, on a side wall and substantially near its base, orifices 31 of very small sections so that the product diffuses during the flow of water on it in the vase 30. The vase 30 is preferably placed a few millimeters from the bottom of the tank. For example, the household product is a solid 32 which is eroded by the passage of water over it.

With reference to FIGS. 1, 3, 5 and 11 to 14, the container 1 comprises a hooking device 40 making it possible to grip the container or to suspend it. According to the embodiment shown, the attachment device 40 is located on the periphery of the tank along a transverse side, near the basin. For example, the attachment device is an attachment bar 40, preferably cylindrical.

Optionally, the handle 102 of the brush includes a hooking device 103 arranged and configured to cooperate with the hooking bar 40 of the container 1. According to the embodiment shown in FIG. 10, the hooking device 103 is arranged at one end of the handle 102. The attachment device 103 has the form of a collar of substantially rectangular section and preferably comprising three hooks for cooperating with the attachment bar 40. On a first face of the attachment device, there is arranged a hook 103B of curved shape protruding upwards and a hook 103C of curved shape protruding downwards. The hook 103B and the hook 103C together form a double hook in the shape of a "C" so that the space between them is sufficient to insert the hanging bar 40. On a second face of the hanging device 103, opposite to the first side, it is arranged a

-21 hook 103A of curved shape projecting upwards and allowing the hanging of the hanging bar 40.

With reference to FIG. 11, the head 101 of the brush is placed outside the basin 3 and the attachment device 103 cooperates with the attachment bar 40, by means of the hook 103A. Referring to Figure 12, the user can lift the tray 1 with the hook 103A without stooping. The user can position the container in a substantially vertical position. The attachment device 103 and the attachment bar 40 make it easier to transport the container by the user. During this vertical positioning, the cleaning liquid contained in the basin returns to the tank, and the used liquid contained in the collection chamber cannot escape due to the position of the outlet 9 of the collection chamber and the discharge orifice 12 which are then situated at a height greater than the height of the level of waste liquid in the collection chamber. In this position, neither the cleaning liquid contained in the tank, nor the used liquid contained in the collection chamber can spill. This feature allows the user to be able to raise the bin using the broom, transport it vertically to another room, then place it horizontally on the floor to clean this other room. During this horizontal reset of the tank on the ground, the cleaning liquid contained in the tank returns to the basin, and the used liquid contained in the collection chamber returns to horizontal without being able to escape.

Then with reference to FIG. 13, the user can hang the brush and bin assembly by means of a hook, not shown, at one end for gripping the handle of the brush, opposite the end presenting the device d 'hooking the broom, for example to suspend the assembly along a wall. Referring to Figure 13, the user can use the hook 103B to suspend the tray and brush assembly. This arrangement makes it possible to further insert the head 101 of the brush in the basin 3.

With reference to FIG. 14, the brush and bin assembly can also be placed on the ground via the bin. The tank is then in the upright position and is supported on the ground 51 by a peripheral transverse side 45 of the tank. Preferably, the side 45 is oblique so that the support on the ground generates a

-22 automatic support against a neighboring wall. The brush then rests on the tray 1 via the hook 103C.

These characteristics have the advantage of making it possible to store easily and in a reduced space the cleaning container or the container and brush assembly.

We will now describe with reference to Figures 4a to 4f, the tray 1, according to the embodiment, during its use and in particular in the cleaning position. By cleaning position is meant the position in which the bottom lf of the tank is substantially parallel to the ground. At the start of the cleaning operation and with reference to FIG. 4a, the tank 2 is filled or almost filled with cleaning liquid L. According to another embodiment shown in FIG. 6a, the tank 2 is also filled with cleaning liquid . The tank 2 can be completely filled when placed in an inclined position as described above during filling, then a quantity of cleaning liquid can flow from the tank 2 to the basin 3 enough to submerge the water. minus an opening 5 which interrupts the transfer of liquid L. Then, with reference to FIG. 4b, the user positions the head 101 of the mop 100 in the basin 3 to moisten or soak the spongy body 104 before rubbing the ground with clean. In the case of a mop with mops and with reference to FIG. 6c, the mops 104 of the mop are preferably lying in the basin 3 to be moistened or soaked. If enough cleaning liquid has been removed, the at least one opening 5 provides an air intake for the tank 2 which again causes the transfer of the cleaning liquid L from the tank 2 to the basin 3 which lowers the level cleaning fluid in tank 2, see Figure 4c. Once the user has rubbed a few square meters, for example 2 to 4 square meters, he spins the spongy body 104 from the head 101 of the brush using the wringing zone 10, see FIG. 4f. For example, the tray 1 is placed against a wall 50 to carry out the spinning step. This allows to take support and stabilize the tank. In addition or in order to avoid leaning against a wall, the container includes non-slip studs arranged under the latter, so that it rests on the floor in the cleaning position by means of the non-slip studs. In the case of a mop and with reference to the figure

-236d, the user places the head of the broom in the spinning cone and turns the handle 102 of the broom in order to rub the fringes against the ribs of the spinning area. During the spin, the used liquid U flows into the collection chamber 8 which fills a little more with each spin, see in order Figures 4c, 4d and 4e. As these stages follow, the level of cleaning liquid L drops in the tank 2 while it remains constant in the basin 3 and the level of the used liquid U increases in the collection chamber 8.
