Definitions

  • the invention relates to a wet cleaning device.
  • Hard floor cleaning is traditionally done by first vacuuming the floor, followed by mopping it. Vacuuming removes the coarse dirt, while mopping removes the stains. These days there are more and more appliances on the market that claim to vacuum and mop in one go. Also robot vacuum cleaners offer the solution of vacuum cleaning and mopping the floor. For this a water tank with mop is attached towards the (vacuum cleaning) robot.
  • US2014033468 discloses a floor tool in the context of a vacuum cleaning appliance that has a dual functionality.
  • the floor tool provides a suction cleaning function and, secondly, the floor tool has the capability to carry a cleaning element, preferably in the form of a wiping sheet, to wipe the floor surface at the same time as vacuuming the floor surface.
  • the suction nozzle is configured to float relative to the connecting neck of the floor tool which confers several benefits. Firstly, the downwards force applied to the user via the neck is transmitted directly to the support member, but not to the suction nozzle, the downwards pressure improving the cleaning performance of the wipe sheet carried on the support member. Secondly, since very little downwards force is applied to the suction nozzle, it is able to ride lightly across the floor surface which benefits the pickup performance of the suction nozzle.
  • US2017367552 discloses a self-moving floor treatment device that comprises a machine body base and a water tank.
  • a cleaning cloth is attached onto the bottom of the water tank, and the water tank is connected to the bottom surface of the machine body base in a manner of floating up and down.
  • the water tank and the cleaning cloth can float up and down within a certain range of space.
  • the force that actually acts on the floor is just the gravity of the water tank and the cleaning cloth themselves and does not comprise the gravity of the machine, compared with a common product, the friction force between the cleaning cloth and the floor is reduced, the phenomenon that the machine slips on the floor with water can be effectively avoided, the floor cleaning efficiency is improved and the obstacle crossing ability of the machine with the water tank is improved.
  • a wet cleaning device comprising a mopping unit for wet cleaning a surface, and an arrangement for increasing a pressure of the mopping unit to the surface by means of suction.
  • This arrangement includes a hose at a side of the mopping unit, the hose having an opening for applying suction to the surface.
  • the hose may be present at opposite sides of the mopping unit.
  • the hose may be present around the mopping unit.
  • a suction power of the arrangement is controllable.
  • the suction power is controllable in dependence on a detection of stains, a speed of the wet cleaning device, and/or a type of the surface. If the wet cleaning device is formed by a mopping robot vacuum cleaner, the suction for the arrangement is advantageously a part of a suction generated for vacuum cleaning.
  • the invention is based on the recognition that wet cleaning devices like robot vacuum cleaners are preferably not very heavy, so that a user can easily pick them up.
  • wet cleaning devices like robot vacuum cleaners are preferably not very heavy, so that a user can easily pick them up.
  • a surface e.g. a floor
  • wet cleaning device needs to be low in weight to be easily lifted, but on the other hand, it should provide enough pressure on the floor to enable the wet cleaning device to mop the surface properly. To overcome this contradiction, it is necessary to provide a way to apply force on the ground without making the wet cleaning device heavier.
  • Embodiments of the invention provide an area of under-pressure around the mopping unit so that the mopping unit will suck itself to the ground.
  • the under pressure can advantageously be generated by leading a part of the airflow of the vacuum cleaner through a tube system around the mop.
  • Fig. 1 shows a bottom view of an embodiment of a wet cleaning device in accordance with the invention.
  • Fig. 2 shows a cross-section of the embodiment of Fig. 1.
  • Figs. 1 and 2 relate to a wet cleaning device WCD formed by a mopping robot vacuum cleaner.
  • the mopping robot vacuum cleaner has wheels W, a nozzle N with an optional rotating brush B, and a mopping unit MU.
  • the mopping unit MU has a liquid tank (not shown) and a (replaceable) cleaning cloth.
  • a suction tool ST is provided at a side of the mopping unit MU.
  • the suction tool ST is formed by a hose having multiple openings around the mopping unit MU.
  • the hose may have a slit-shaped opening.
  • the hose may be made of rubber or some suitable plastic or other suitable material.
  • the hose may be glued to the mopping unit MU.
  • a dirt separation and collection unit DC dirty air from the nozzle N is guided to a dirt separation and collection unit DC, through which an airflow is generated by a fan F.
  • part of the airflow generated by the fan F is used to generate suction for the suction tool ST.
  • a valve V is present to control how much airflow can be used for the suction tool ST.
  • the valve V may be formed by means of a clamp around a hose: if the hose is compressed by the clamp, less suction is available for the suction tool ST.
  • a processor anyway present in a robot cleaner receives data (e.g. from a camera (not shown), and has software that can determine the presence of stains and the surface type from the camera image. This software may involve artificial intelligence based on a trained neural network.
  • the wheel speed can be derived e.g. from an amount of current drawn by a motor that rotates the wheels W : if the current is relatively high, the motor has to work hard, so that it makes sense to reduce the suction for the suction tool to reduce friction.
  • the mopping unit MU is surrounded by the suction tool ST, but in other embodiments, the suction tool ST is just present at a side or at opposite side of the mopping unit MU.
  • the suction tool ST does not need to be along a side, i.e. it does not need to have an elongated shape, as long as it results in the mopping unit MU exercising an increased pressure on the surface.
  • the wet cleaning device of the present invention may also be arranged for cleaning (vertical) surfaces like windows or walls. The wet cleaning device of the present invention does not need to have a vacuum cleaner function.
  • the wet cleaning device may or may not use the vacuum cleaner fan F for creating suction to increase a pressure of the mopping unit to the surface; a separate low-power fan may be used for this purpose, and this may result in the advantage that a better control of mopping pressure may be achieved, independent of vacuuming activities.
  • a wet cleaning device having a vacuum cleaner function may have different operation modes: (1) only vacuum cleaning, (2) only wet cleaning, and (3) both vacuum cleaning and wet cleaning. In the second mode, use of a separate suction unit for generating under-pressure may result in the advantage that less energy is consumed.
  • any reference signs placed between parentheses shall not be construed as limiting the claim.

Abstract

La présente invention concerne un dispositif de nettoyage par voie humide (WCD) comprenant une unité de nettoyage (MU) destinée à nettoyer une surface par voie humide, et un agencement (ST) destiné à augmenter une pression de l'unité de nettoyage (MU) sur la surface par aspiration. L'agencement comprend un tuyau sur un côté de l'unité de nettoyage (MU), le tuyau ayant une ouverture destinée à appliquer une aspiration à la surface. Le tuyau peut être présent des deux côtés de l'unité de nettoyage (MU). En variante, le tuyau peut être présent autour de l'unité de nettoyage (MU). Une puissance d'aspiration de l'agencement peut de préférence être commandée. La puissance d'aspiration peut avantageusement être commandée en fonction d'une détection de taches, d'une vitesse du dispositif de nettoyage par voie humide (WCD) et/ou d'un type de surface. Si le dispositif de nettoyage par voie humide (WCD) est formé par un robot aspirateur nettoyeur, l'aspiration pour l'agencement (ST) fait avantageusement partie d'une aspiration générée pour le nettoyage par aspiration.
