Description

Technical Field

[0001] This application relates to the field of floor cleaning devices, such as broom-type floor cleaning devices, which allow the suction of dust and waste present on a surface to be cleaned, such as tile, parquet, laminate, mat, or carpet, and allow simultaneous steam cleaning of the surface to be cleaned. Background Technology

[0002] Floor cleaning devices, in a known manner, include a main body equipped with a suction end piece, a gripping handle mechanically connected to the main body, a suction cup configured to rest on the surface to be cleaned and equipped with a front cleaning roller and a rear cleaning roller, and a suction motor housed in the main body and configured to generate airflow through the suction cup.

[0003] To improve the cleaning performance of such floor cleaning devices, it is known to equip the suction cups of such floor cleaning devices with a steam generator and a steam distribution circuit, the steam distribution circuit being fluidly connected to the steam generator and configured to supply steam to one of the cleaning rollers or optionally to the floor to be cleaned.

[0004] However, because the steam generator is housed within the suction cup body, this type of suction cup has a relatively large size in terms of height, which impairs its operability and also hinders cleaning surfaces located under low furniture. Furthermore, this configuration of the suction cup requires a specially shaped top cover to define an internal compartment capable of receiving the steam generator.

[0005] In addition to the drive motor that drives the front and rear cleaning rollers to rotate, the presence of a steam generator inside the suction cup also causes high temperatures inside the suction cup, which may damage the operation of the drive motor and thus compromise the reliability of the aforementioned type of floor cleaning device. Utility Model Content

[0006] This application aims to overcome all or some of these shortcomings.

[0007] The technical problem upon which this application is based is specifically to provide a floor cleaning device that is compact and reliable, while also having improved cleaning performance.

[0008] Therefore, this application relates to a floor cleaning device, comprising: - The main body is equipped with a suction end piece. - A grip handle mechanically connected to the main body. - A suction cup, comprising: The suction cup body includes a base plate with a lower surface, the lower surface being oriented towards the surface to be cleaned. o A front suction nozzle leading to the front of the base plate, for example, in the front part leading to the lower surface of the base plate, and a rear suction nozzle leading to the rear of the base plate, for example, in the rear part leading to the lower surface of the base plate. A front cleaning component, such as a front cleaning roller or a front cleaning brush, is associated with a front suction nozzle and configured to contact the surface to be cleaned; and a rear cleaning component, such as a rear cleaning roller or a rear cleaning brush, is associated with a rear suction nozzle and configured to contact the surface to be cleaned. The front and rear cleaning components are mounted to rotate about a first and a second rotational axis that are substantially parallel to each other. o Steam distribution circuit, configured to supply steam to the forward cleaning component and the rear cleaning component, and A connecting sleeve is fluidly connected to the front and rear suction nozzles, and the suction end of the body is mechanically and fluidly connected to the connecting sleeve. - A suction motor housed within the main body, configured to generate airflow through the suction cup and suction end piece, and - A steam generator configured to supply steam to the steam distribution circuit, the steam generator being housed in the body and configured to supply steam to the steam distribution circuit when the suction end is connected to the connecting sleeve.

[0009] By integrating the steam generator into the main body and moving it away from the suction cup, the height and volume of the suction cup can be significantly reduced, allowing for easy cleaning of surfaces, especially those located under low furniture.

[0010] Furthermore, this arrangement of the steam generator allows for limiting temperature rise within the suction cup body and maintaining the integrity of the rotation drive mechanism of the front and rear cleaning components.

This configuration of the steam distribution circuit improves the cleaning performance of the floor cleaning apparatus according to this application (because the front and rear cleaning members are heated by steam), while allowing for faster drying of the front and rear cleaning members, and enhancing the disinfection and cleaning of the front and rear cleaning members through the steam directly sprayed onto them.

[0017] According to one embodiment of this application, the front steam jet component and the rear steam jet component are located between the front cleaning component and the rear cleaning component. This arrangement of the front steam jet component and the rear steam jet component allows for a further reduction in the height and volume of the suction cup.

Similarly, the rear steam injection member 35 includes an upper wall and lower wall (not visible in the figure) defining the rear steam circulation passage, which is configured to direct steam to the rear cleaning member 28. This configuration of the front steam injection member 34 and the rear steam injection member 35 ensures the maximum steam temperature when the steam comes into contact with the respective cleaning member. The upper and lower walls of each steam injection member more specifically form a space for restricting and guiding steam toward the respective cleaning member.

However, according to a variant embodiment of the present application, the front water spray member 39 may include a single front water spray nozzle, and the rear water spray member 41 may include a single rear water spray nozzle.

[0096] During the cleaning operation of the surface to be cleaned, the user can control the spraying of water and / or steam on the front cleaning member 27 and the rear cleaning member 28 by actuating, for example, a first control button and a second control button respectively provided on the grip handle 5.

[0097] According to one embodiment of this application, which is not shown in the figure, the suction cup 6 may not have a water distribution circuit configured to supply water to the forward cleaning member 27 and the rear cleaning member 28.

[0098] According to one embodiment of this application (not shown in the figure), the suction cup 6 may also be provided with a steam jetting device, which is fluidly connected to the steam distribution circuit 32 and configured to jet steam directly onto the floor to be cleaned.

[0099] Of course, this application is by no means limited to the embodiments described and illustrated, which are given only as examples. Modifications are still possible without departing from the scope of protection of this application, particularly from the perspective of the composition of various elements or by substitution with technical equivalents.
