Definitions

• the present invention relates to a cleaning product dispenser for a floor and / or window treatment device comprising an electric pump connected, on the one hand by a first pipe to a suction nozzle connected to a water tank. clean, and on the other hand, to a discharge nozzle connected to a second pipe connected to a cleaning tool, and thus establishing a circulation of pressurized water between the water tank and the cleaning tool.
• the invention relates more specifically to a dispenser comprising a jar containing a cleaning product, closed by a cover and having an outlet chute connected by a suction device to one or the other of said pipes so entraining the cleaning product by suction in one or the other of said lines.
• this kind of dispenser leads to a significant consumption of cleaning product and therefore a cost for the function provided which is difficult to justify in the eyes of the user.
• the present invention therefore aims to remedy the above drawbacks.
• the chute comprises a manual adjustment device making it possible to continuously vary the flow rate of the cleaning product to the suction device.
• the user is master of the dosage of the cleaning product and can therefore carry out different cleanings during the same treatment operation for floors and / or windows; for example, he may send more cleaning product into the water to assure and remove stains, or less product to avoid the proliferation of foam on a smooth floor that would be difficult to suck up.
• FIG. 1 shows in vertical section a dispenser according to the invention arranged in a clean water tank of a floor and / or window treatment device.
• the cleaning product dispenser referenced as a whole by the reference 1 is arranged in a tank 2 of clean water which is part of an apparatus for treating floors and / or windows not shown which comprises in a manner known per se an electric pump shown diagrammatically at 3 connected, on the one hand by a first pipe 5 to a suction nozzle 4 connected to the reservoir 2, and secondly to a discharge nozzle (not shown) connected to a second pipe 6 for supplying water to a soil cleaning tool shown diagrammatically by the references_.
• This tool is, for example in the case of a cleaning device comprising a dirt suction group, a squeegee comprising a suction port and a nozzle connected to the second pipe 6.
• This tool could also be a scraper of window cleaning with built-in nozzle.
• the dispenser comprises a jar 7 containing a cleaning product (detergent or other), closed by a cover 8 and having an outlet chute 9.
• a cleaning product detergent or other
• the jar 7 is arranged vertically within the reservoir 2 and its chute outlet 9 crosses the bottom 11 of the jar 7.
• the cover 8 is preferably located above the upper face 12 of the tank 2 so as to allow easy filling of the jar and an immediate view of its contents.
• the outlet chute 9 is connected by a suction device 13 to one or the other of the conduits 5 or 6 so as to entrain the cleaning product by suction in one or the other of the said conduits.
• the outlet chute 9 is connected via a connector 10 to the suction device 13 itself in communication with the suction nozzle 4 thus ensuring a premixing of the product of cleaning before mixing in the pump 3.
• the outlet chute 9 is connected to the suction device itself connected to the second conduit 6, downstream of the pump thus preventing the cleaning product from entering the pump and could cause damage to this pump, mixing therefore occurs after the pump.
• the outlet chute 9 includes a manual adjustment device 14 making it possible to continuously vary the flow of the product to the suction device 13.
• This adjustment device comprises a cylindrical body 15 pierced with a bore 16 central, vertically oriented and forming a chamber, having in its internal wall a groove 18, one end 19 of which opens into the jar 7 and the other end 20 of which is occluded, as well as a plug 21 having a head 22 of radial dimension corresponding to the bore and having a passage 23 capable of bringing the groove 18 into communication with the outlet 24 of the bore 16, the said barrel being movably mounted in the chamber 16 so as to regulate the flow between the groove and the corridor.
• the chute 9 and the body 15 of the adjusting device 14 are formed in one piece.
• the plug 21 has a corridor in the form of a vertical notch and is mounted vertically displaceable in relation to the groove so as to vary the axial length of the notch and therefore the flow of the product. cleaning to outlet 24.
• the corridor 23 has a mouth transverse to the groove 18, and the plug 21 is mounted movable in rotation in the bore 16 of the chamber.
• the mouth of the passage 23 has a variable section with regard to the groove 18 thus causing a variation in the flow rate.
• the body is made of a flexible and molded material, such as for example a silicone, while the plug is made of a rigid material such as a plastic material.
• the plug 21 comprises a rod 25 arranged along the same vertical axis as that of the bore 16 and comprising a low end forming the head 22 and a high end 26 projecting from the cover 8 and comprising a button operation 27.
• the suction device 13 comprises two aligned chambers 29 and 30, one of suction, the other of discharge, connected by a connector 31 forming a venturi.
• This connector 31 further comprises a calibrated nozzle 32 arranged transversely and connected to the trough 9.
• the suction nozzle and the suction device 13 constitute a single part and the connector 10 is also part of the single part and is connected to the outlet chute 9 of the jar 7 .
• the suction chamber is equipped with a non-return valve 33 located at its mouth 34.
• the suction nozzle 4 and suction device 13 assembly comprises a barrel 35 having on its outer surface a helical thread and passing through an orifice 36 formed in the bottom 37 of the clean water tank 2, said nozzle being fixed so tight on the bottom 37 by means of a nut 38 screwed onto the helical thread.
• a first phase the user operating the cleaning tool S_ starts the pump 3 thus causing the suction of the water through the suction nozzle 4, the non-return valve 33, the chamber 29, the connector 31 then the chamber 30. Thanks to the venturi effect caused by the connector 31, a depression is created at the nozzle 32 proportional to the flow rate of the liquid and, via the adjustment device, the user adjusts precisely the output flow of the cleaning liquid contained in the jar 7. For this adjustment, the user turns the operating button 27 so as to drive the plug 21 to obtain different coincidences between the groove 18 and the mouth of the corridor 23, depending on whether it rotates said button in different directions.
• the cleaning agent thus dosed is sucked in via the nozzle 32 under the effect of the vacuum and is mixed in the discharge chamber 30, then led via the line 5 to the pump 3 and via the line 6 to the cleaning S.
• the user can, at his request and during the cleaning operation, adjust the flow of the cleaning product precisely and continuously to the flow of clean water sucked in by the pump 3.
• This pump can therefore be of a simple design knowing that the suction at the nozzle 32 creates a vacuum in the adjustment device 14 proportional to the flow of the clean liquid sucked.
• the invention is not limited to the embodiment described above, but can be extended to other adjustment devices with similar mechanical operation.
