Description

Machine for cleaning and rinsing floors Technical Field The object of the present invention is a machine for dry cleaning and cleaning floors. Background There are basically two types of machines currently available for cleaning and treating floors, machines that extend horizontally and comprise a rigid fixed guiding handle, the height of which can be adjusted, and a newer concept of machines in which the handle is longer, has no fixed position, but is free to rotate within at least one axis, and in which a part of the machine components (e.g. a tank and a power battery) are arranged along or housed in the guiding handle. The first type of machine, the so-called "horizontal" machine, has the disadvantage of being cumbersome and not easy to handle in small spaces (for example under a sink or table or other type of furniture) or when they must generally follow a path that makes a sharp turn or difficult to walk. The second type of machines, so-called "upright" machines, are easier to operate in small spaces, since they are more compact and are generally equipped with tiltable handles suitable for guiding the lower parts of the machine. In particular, at least one of the two tanks in the "upright" machine, one containing cleaning liquid, acts as a recovered one on the handle, in order to reduce the volume of the lower part, thus allowing the machine to be more usable with small spaces available. However, floor cleaning machines of this type also have disadvantages, in this case concerning ergonomics and operability. In fact, in this type of machine, at least one of the two tanks, the cleaning and recovery tank, is located on the handle and the other tank is located on the lower part. In this configuration, during operation of the floor cleaning machine, an imbalance may occur due to movement of liquid mass transfer in the tank. The movement of the handle has an effect on the load actually applied to the lower part of the machine and this undesired effect may result in a similar effect due to the movement of the liquid in the tanks on the lower part and may also become very troublesome for the operator due to the height of the water filling of the two tanks. The result is poor operability, which can present significant difficulties to the operator. Other problems affecting the lower part of the vertical machine with the recovery tank are linked to the small size of the recovery tank itself, which rarely exceeds 5 liters, in fact limiting the operational autonomy of the floor cleaning machine. Some machines of this type are only 15 minutes autonomous, which is far from sufficient for professional use. Finally, a problem with upright machines having a recovery tank in the lower part is that, especially in the event of sudden movements or impacts against obstacles, the movement of the mass transfer of the large amount of liquid contained in the recovery tank may interfere with the suction system adapted to convey the liquid recovered from the floor to the tank, thus causing malfunctions of the suction system itself and of the overall floor cleaning machine. Generally, upright floor cleaners present problems associated with ergonomics and operability because they have a very light lower part and a heavy handle that must be supported by the user. Further, when the handle is highly tilted, for example, the lower part of the machine performs a turn and the brushes together perform a pushing action, the center of gravity of the machine may be significantly moved, resulting in sliding and slipping of the lower part, thereby resulting in difficulty in operability and inefficiency of operation of the machine. It is therefore an object of the present invention to provide a floor cleaning machine which solves the problems of the prior art by introducing a new lower part which is characterized by a weight distribution which ensures that the wheels and brushes or rollers have the necessary grip to maintain stability and operability during use. Disclosure of Invention The floor cleaning machine according to the present description solves the technical problem described by introducing a lower part comprising a double tank and optimizing the arrangement of the parts, resulting in a uniform and consistent balance suitable for ensuring ergonomics and ease of use of the machine. The machine of the present description comprises a lower part, characterized by an innovative balancing, which is achieved by the cooperative use of at least one mobile support and two tanks, one for the cleaning liquid and the other for the recovery of the liquid on the floor after use, which are suitably shaped and arranged on the lower part and preferably, but not necessarily, nested one inside the other. This configuration allows the weight of the lower part housing the two tanks to remain constant, regardless of their respective charging and discharging, and uses a central positioning of one or more load-bearing wheels in order to optimize the weight d
