Definitions

  • the present invention relates to washers, and in particular to a washer comprising a drain with valved vent of new design.
  • a washer comprising a drain with valved vent of new design.
  • washing appliances such as washers, washer/dryers and the like are provided with a water drain that runs directly from the drain pump to the wall-mounted drain mouth.
  • the water drainpipe rather than coming out of the machine at the bottom comes out at the top leaving inside the machine a vertically arranged length of drainpipe that acts as a reservoir and a water column which exerts a certain pressure.
  • a pressure is used to operate a float or ball valve located on the tank spout, so that when the water with the detergent is loaded in the tank a portion of said water is not immediately wasted down the drain.
  • the drain has a vent pipe that allows the entrance of air, so as to cancel the siphon effect, and is provided with a valve that is closed during the drain phase to prevent water leakages.
  • This pipe is usually connected to the detergent drawer or directly to the tank so as to avoid that the water possibly leaking through the pipe in the first moments of the drain phase, when the valve may be not yet perfectly closed, can get out of the washer.
  • the object of the present invention is to provide a drain with valved vent which overcomes said drawbacks.
  • This object is achieved by means of a drain in which the vent is provided with a flap valve integrated into a T-fitting where the three above-mentioned pipes meet.
  • a drain according to the present invention includes a substantially T-shaped fitting 1 where the above-mentioned three pipes meet, namely:
  • a flap valve 6, better illustrated further on, is fitted in a seat 8 formed in arm 1c of fitting 1 and engages two teeth 9 located above and below said seat 8.
  • the assembly is then overmolded with a rubber cover 7 that covers substantially the whole T-fitting.
  • the flap valve 6 is better illustrated in Fig.3 that shows how the valve is substantially C-shaped, with a central projection 6a shaped to mate with seat 8 formed in fitting 1 as well as a pair of windows 6b (only one visible in the figure) for coupling with teeth 9.
  • a flap shutter 10 extends orthogonally at a central position from projection 6a and is connected thereto, on the side opposite to the closure abutment side, preferably also through a rib 11 acting as a biasing member for a faster closing of the valve.
  • valve 6 opens, when necessary, to allow the entrance of air into fitting 1 through pipe 4, arm 1c and the relevant entrance hole 12 on which the flap shutter 10 of valve 6 rests, which valve is made of a flexible material, preferably silicone rubber.
  • shutter 10 abuts on hole 12 to prevent the leakage of water coming from pipe 2 so that all the water is drained through the drainpipe 3.
  • a manufacturing method for the above-described drain therefore essentially includes the steps of:
