Definitions

• the invention refers to an integrated tub overflow system for a top-loading rotating-drum washing machine.
• the integrated overflow system consists of a flexible pipe connected to the tub, directing excess water to the base of the machine away from the electrical equipment.
• the purpose of the present invention is to provide a solution for these disadvantages.
• the invention as it is characterised in the claims, resolves the problem by creating an integrated overflow system for a top-loading washing machine, whereby, on the one hand, all evacuation piping, be it rigid or flexible, is eliminated and, on the other hand, the said system be fully integrated in the machine tub during its manufacturing of the tub, without use of additional parts.
• the advantages procured by this invention consist primarily in that there is no risk of a leak around the overflow connection or any risk of foam overflow or vapour production. Mounting the tub in its frame is facilitated by the lack of specific parts to attach and connect. The flow resulting from a potential overflow is channelled towards an area removed as far as possible from the electrical equipment.
• FIG. 1 shows a partial plan view of the tub's left flange joint, around the system
• FIG. 2 shows a partially exploded perspective view of the tub, around the system
• FIG. 3 shows a side perspective view of the tub before its left flange is mounted.
• the figures represent an integrated overflow system for a top-loading washing machine according to the invention, whose tub includes, around its junction plane with the corresponding flange 3, a system forming a labyrinth 10 open on the side of the junction plane with the flange 3, including an ascending hollow baffle 11 that starts inside the tub at a predetermined spot and opens into a meander forming a siphon 12, which opens into a room 13 with an L-shaped deflector 131 by communicating on the one hand with a descending baffle 14 next to the ascending baffle 11 and coming into the open air around the base of this last baffle and, on the other hand, with a nozzle 15 connected directly to the room 13 and coming out behind the L-shaped deflector 131.
• the labyrinth 10 for the flow of excess water is made as a hollow in the junction plane of the tub body 1 with the corresponding flange 3, which includes the labyrinth 10 lid 31 that in this way, during assembly of the left flange 3 with the machine tub body 1 , definitively materialises the baffles 11 and 14 of the labyrinth 10 thereby constituting the overflow according to the invention.
• the tub body 1 is assembled with its flanges 3 according to the conventional technique, without any other constraint than to align the system with its lid 31, as shown in figure 2.
• the siphon 12 provided it is filled with water, resists the passage of foam and vapour.
• condensation water than can appear in the upper part of the system, it flows normally inside the drum through the 5 ascending baffle 11 of the labyrinth 10 by overflowing " the siphon 12 as soon as the siphon is full.
• the siphon 12 fills up with condensed vapour produced during the wash cycle.
• the overflow according to the invention has been designed for top-loading rotating- drum washing machines, but there is no reason it cannot be used on front-loading machines, subject to minor adaptations according to current techniques. 0
