Definitions

  • Lavatories may be divided into two main groups, namely, water closets and earth closets.
  • the object of this invention is to provide an earth closet which is practically independent of the supply of water and can be devised such that the evacuated matter is always kept in a practically closed system.
  • an earth closet of the type comprising a closet pan having a bottom discharge opening for evacuated matter
  • the above object is attained in accordance with the invention by the provision of a cylinder located below the pan and provided with a plunger which in a retracted position uncovers a receiving chamber formed by said cylinder, the receiving chamber being in direct communication with the discharge opening of the closet pan and the discharge end of the cylinder being adapted to be put into communication with a drain pipe.
  • the plunger When the closet is not in use the plunger is in its forward end position and isolates the drain pipe from the discharge opening of the closet pan. In this way eventual foul gases from evacuated matter in the drain pipe are prevented from forcing their way out into the room around the closet.
  • the drain pipe is made of plastic and preferably communicates with a covered or closed collecting container so that evacuated matter will be kept in a closed system. Consequently, the consumption of water is extremely low as compared with water closets and in addition pollution of water courses in the neighbourhood is avoided, since the evacuated matter can be collected in a container.
  • FIG. 1 is a longiutdinal sectional view of a closet according to the invention.
  • FIG. 2 is a top view of the closet pan.
  • FIG. 3 is a diagrammatic view of a dwelling house equipped with a closet according to the invention, and
  • FIG. 4 illustrates the connection of a drain pipe of the closet to a transportable collecting container.
  • the closet pan 1 is supported by a foot in the form of a downwardly tapering casing 2 which is bolted for instance to a floor 3.
  • an obliquely downwardly sloping cylinder 4 provided with a plunger 5 having a sealing member 6 at its front end.
  • FIG. 1 the plunger is shown in solid lines in its forward end position and with chain-dotted lines in its retracted end position.
  • the plunger By means of a link 7 the plunger is connected to a plate 8 secured to a pivotally mounted lever 9 which carries a lid 10. If the lever is swung down and the plunger assumes its forward end position, the lid 10 covers the closet seat 11.
  • the closet pan 1 At the rear part of its bottom the closet pan 1 has a discharge opening 12 in direct communication with a corresponding opening 13 in the upper side of the cylinder 4.
  • the cylinder At its discharge end the cylinder has a restricted portion in the form of a short vertical pipe 14 which is connected to a drain pipe 15.
  • the drain pipe passes through a hole in the floor and extends outwards for instance to a covered sink 16, FIG. 3, or to a closed transportable collecting container 17, FIG. 4.
  • the drain pipe 15 and preferably also the other parts of the closet are advantageously made of plastic so that evacuated matter and other dirt can readily glide away from the surface of the plastic.
  • the lever 9 is swung upwards together with the lid 10 to the position indicated by chain-dotted lines.
  • the plunger is retracted to its rear end position in which the rear end of the plunger is slightly lifted by sliding up onto a plate spring 18 secured to the bottom of the cylinder. Due to the resulting oblique position of the plunger the bottom of the cylinder is effectively scraped clean by the sealing member 6.
  • a possibility of draining below the plunger is provided by a channel-shaped recess 19 which extends ahead of the front end of the plunger.
  • the plunger has longitudinally extending slots 20, 21 which permit angular movement of the link 7.
  • the plunger At its front end the plunger has a drain hole 22.
  • Evacuated matter drops through the openings 12, 13 and deposits in the forward end of the cylinder which is of suflicient volume to hold the dropping matter.
  • the lever 9 If thereupon the lever 9 is swung down the lid 10 covers the closet pan and the plunger 5 is forced down to its front end position.
  • the plunger isolates the discharge openings 12, 20 and 21 from the drain pipe and the evacuated matter is forced under compression through the short pipe 14 into the drain pipe 15. Due to the compression in the pipe 14 and due to the fact that the drain pipe 15 is of greater internal diameter than the pipe 14, evacuated matter will drop into the drain pipe 15 without significant obstruction.
  • the pan 1 and the openings 12, 13 can be readily rinsed if required, with a minimum amount of water.
  • a closet comprising a closet pan having a bottom discharge opening for evacuated matter, a cylinder located below the pan and provided with a plunger which in a retracted position uncovers a receiving chamber formed by said cylinder, the chamber being in direct communication with the discharge opening of the closet pan and the discharge end of the cylinder being adapted to be put into communication with a drain pipe.
  • a closet as claimed in claim 1 comprising a clear ance between the cylinder and the retracted plunger which clearance permits the rear end of the plunger to be slightly lifted under the action of a spring device at the bottom of the cylinder, whereby to have the bottom of the cylinder scraped clean during the discharge stroke of the plunger.
  • a closet as claimed in claim 1 in which the bottom of the cylinder has a longitudinally extending channelshaped recess which in the retracted position of the plunger extends slightly ahead of the front end of the plunger and rearwards to permit draining from the space behind the plunger in the retracted position thereof.
  • a closet as claimed in claim 1 in which the plunger is operated by means of a pivotally mounted lever which carries a lid adapted to be placed over the closet seat as the lever is swung down and the plunger performs its discharge stroke.
