• TITLE Autonomous cleaning robot equipped with a wet cleaning device
• the present invention relates to the field of autonomous cleaning devices equipped with a wet cleaning device, and more particularly to the field of robot vacuum cleaners that can move independently on a surface to be cleaned and can suck dust and waste present on the surface to be cleaned, which may for example be tiling, parquet, laminate, carpet or a rug, and optionally washing the surface to be cleaned simultaneously with a vacuuming operation.
• Document EP3257416A1 discloses an autonomous cleaning robot comprising:
• main body comprising a lower face which is configured to be oriented towards a surface to be cleaned and a suction opening provided in a front part of the main body and opening into the lower face of the main body
• a wet cleaning device comprising two mop supports which are each mounted movable in translation relative to the main body in a direction of translation, and two mops mounted in a removable manner respectively on the two mop supports, the mops being configured to be in contact with the surface to be cleaned, and
• the two mop supports are mounted respectively on a front part of the main body and on a rear part of the main body, and are arranged on either side of the axes of rotation of the drive wheels.
• the direction of translation of the mop supports extends parallel to a main direction of movement of the autonomous cleaning robot, that is to say along a longitudinal direction of the autonomous cleaning robot.
• the present invention aims to remedy these drawbacks.
• the technical problem at the basis of the invention consists in particular in providing an autonomous cleaning robot which is of simple, economical and compact structure, while presenting high cleaning performance.

• the two mop supports are located behind the axes of rotation of the drive wheels, and the direction of translation extends substantially parallel to the axes of rotation of the two drive wheels. In other words, the direction of translation extends transversely to a main direction of movement of the autonomous cleaning robot.
• Such an arrangement of the mop supports makes it possible to increase the pressing force exerted by each of the mops on the surface to be cleaned, and therefore to increase the friction of the wet cleaning device on the surface to be cleaned, due to the weight exerted by the main body on the wet cleaning device.

Indeed, due to the alternating movements of the mop supports and the proximity of the drive wheels, it would be necessary either to reduce the dimensions of the mops in a longitudinal direction so as not to impact the longitudinal size of the autonomous cleaning robot (which would be detrimental to the quality of cleaning of the autonomous cleaning robot), or to increase the dimensions of the autonomous cleaning robot to allow longitudinal movements of large mops.

• the ejection member 28 is mounted to slide relative to the main body 3 along a sliding direction, which is parallel to the main direction of movement D of the autonomous cleaning robot 2, and between a retracted position (see figure 7) in which the ejection face 28.1 of the ejection member 28 is located set back or close to an insertion opening of the reception cavity 29, and a deployed position (see figure 12) in which the ejection face 28.1 of the ejection member 28 protrudes from the reception cavity 29 and is located at a distance from the insertion opening of the reception cavity 29.
• the device for wet cleaner 14 is configured to move the ejection member 28 to the retracted position when the wet cleaner 14 is mounted on the main body 3.
• the autonomous cleaning robot 2 comprises a biasing element 31, such as a compression spring, configured to bias the ejection member 28 towards the deployed position.
• a biasing element 31 such as a compression spring
• the autonomous cleaning robot 2 also comprises a tank of cleaning liquid 32 which is mounted, for example in a removable manner, on the main body 3.
• the tank of cleaning liquid 32 and the collecting device of waste 12 are superimposed, and are integral with one the other.
• the autonomous cleaning robot 2 can for example comprise a removable reservoir comprising a first compartment forming the cleaning liquid reservoir 32 and a second compartment forming the waste collection device 12.
• the cleaning liquid reservoir 32 could be provided directly on the wet cleaning device 14, and therefore be separate from the waste collection device 12.
• the wet cleaning device 14 further comprises a plurality of liquid outlet ports 33 which are configured to be fluidly connected to the cleaning liquid reservoir 32 and which are configured to supply cleaning liquid to the mops 17 mounted on the mop holders 15.
• the liquid outlet orifices 33 are aligned along an alignment direction which extends perpendicularly to the main direction of movement D of the autonomous cleaning robot 2, and are regularly spaced from each other.
• the liquid outlet orifices 33 are located at the front of the mop supports 15, and for example at the front of the mops 17, and are configured to be oriented towards the surface to be cleaned.
• the autonomous cleaning robot 2 comprises a lifting ramp 38 which extends transversely to the main direction of movement D of the autonomous cleaning robot 2 and which is located at the front of the mop supports 15.
• the lifting ramp 38 may for example have a length corresponding substantially to the distance between the two drive wheels 7.
• the lifting ramp 38 is provided on the wet cleaning device 14, and is for example fixed to the support body 19.
• the lifting ramp 38 comprises a lifting surface 38.1 which is oriented towards a surface to be cleaned and which is inclined backwards and downwards.
• the lifting surface 38.1 is substantially planar.
• the lifting surface 38.1 is more particularly configured to cause lifting of the rear part 3.2 of the main body 3 when an obstacle, presenting itself frontally to the autonomous cleaning robot 2 during a forward movement of the main body 3, comes into contact with said lifting surface 38.1 and slides on said lifting surface 38.1.
• the liquid outlet orifices 33 are provided on the lifting ramp 38 and are distributed along the lifting ramp 38.
• the orifices of liquid outlet 33 open into the lifting surface 38.1.
• the autonomous cleaning robot also comprises a replacement module 41 which is configured to be mounted on the main body 3 in place of the wet cleaning device 14, in particular when cleaning wetness of a surface to be cleaned is not desired.
• the replacement module 41 does not have a mop and can for example be installed on the main body in place of the wet cleaning device 14 when vacuuming a soft floor, such as a carpet, is desired or when a wet cleaning of a hard floor is not desired.
• the replacement module 41 comprises guide means 41 .1 identical to the guide ribs 21 provided on the wet cleaning device 14, and also a bottom wall 41.2 and a rear wall 41.3 respectively similar to the support plate 19.1 and the side wall 19.4 of the support body 19.
• the replacement module 41 could be provided with a module support configured to be mounted on the main body 3 instead of the wet cleaning device 14, and with at minus a passive mop, that is to say which is mounted immobile relative to the module support.
• a replacement module 41 allows a user to wipe the floor to be cleaned, which can be wet or dry depending on the user's needs.
• the replacement module 41 could be provided with a ground treatment element, other than a mop, configured to carry out a mechanical, chemical, thermal or radiant treatment of the ground.
