Definitions

  • BIOLOGICAL TOILET Inventors: Hans Andersson, Talldungen, 45080 Tanumshede, Sweden; I-Iakon Eidet, Sannesundsveien 6, Sarpsborg, Norway Filed: Aug. 8, 1972 Y Appl. No.: 278,864
  • the invention relates to a biological toilet comprising a container in which excrement and possibly garbage is subjected to accelerated fermentation by supply of heat from a heating element and air from a ventilation means having an air outlet.
  • the object of the invention is to eliminate this significant disadvantage and also to eliminate the use of a relatively expensive electric fan which, in the known toilet, constitutes the ventilation means; the toilet, in addition to being operated by electricity, can be operated by a combustible gas, and odour from the outlet, which is undesirable in built-up areas, is substantially removed.
  • the heating element is a closed pipe loop which contains a liquid heattransferring medium and which is arranged in the container between the material to be fermented and a collecting chamber locatedtherebeneath, a corrosionresistant grid being arranged above the pipe loop, said grid being the support for'the material to be fermented, and a thermosiphon pump is inserted in the pipe loop to circulate the medium on supply of heat from a heat source which also heats the medium.
  • pipe loop with pump is adapted to be removed for repairs or replacement without removing the grid with material to be fermented.
  • a flue may be arranged over the heat source, the upper end of said flue projecting a determined distance into the air outlet from the container.
  • the hot air through the flue causes an ejector effect on the gas in the container, so that an electrically operated fan may be omitted and the toilet operated exclusively by combustible gas.
  • thermosiphon pump In order to improve the working condition of the thermosiphon pump, a shunt connection for gas is arranged in parallel therewith in the pipe loop.
  • a part of the pipe loop extends to a location adjacent the bottom of the container.
  • the container In order to economize on heat consumption the container is provided with heat-insulated walls in the form of a hollow, rotary-cast plastic body and is filled with hardened foam plastic.
  • the heavier gases in the container are conducted past a gas flame or an electric heating coil.
  • An agitating mechanism is provided in connection with the grid in order to increase the fall of fermented material from the grid.
  • the heating element may be thermostaticly controlled in order to impart a suitable heat to the fermentation process.
  • FIG. I is a side view in partial section of a biological toilet according to the invention.
  • FIG. 2 is a horizontal projection of the pipe loop with thermosiphon pump.
  • FIG. 3 is a view in greater dimension of a vertical section through the thermosiphon pump, a part of the pipe loop and shunt connection.
  • the container 1 is shown which consists at least of two parts, viz. a bottom portion and a top portion.
  • the container walls can advantageously consist of a rotary-cast, hollow plastic body which is filled with hardened foam plastic.
  • the bottom portion is, at the fore edge or the rear edge, provided with an opening for removal of residue subsequent to fermentation, and also an air inlet.
  • the top portion is provided at the top thereof with a seat opening having a cover 2 and an air outlet 3 located at a somewhat higher position.
  • a corrosion-resistant grid 4 is arranged which supports the excrement or garbage to be fermented.
  • a material which absorbs some of the moisture and partially fills the openings is initially placed on the grid.
  • thermosiphon pump 7 Beneath the grid, a closed pipe loop 5 is arranged wherein a thermosiphon pump 7 is inserted and which is provided with a member 6 projecting to a position more closely adjacent the bottom. of the container.
  • the thermosiphon pump consists of an annular container in the central portion of which a heat source in the form of an electric heat cartridge or a gas burner is arranged.
  • a flue 9 projects as an extension of the said central portion to a determined dis tance within the air outlet 3.
  • a shunt connection 8 for gas is arranged in parallel therewith.
  • the pipe loop and the pump contain a heat transferring medium which is heated by the heat source. As illustrated in FIG.
  • the pump 7, the shunt connection 8 and the heat source may be arranged in a heat insulating casing 11 provided with a pipe 10 through which, due to the heat source and the suction effect from the flue, heavier gases are suctioned from the fermentation and burnt by the heat source so that odours from the air outlet are greatly decreased.
  • a separate gas flame or an electric heat coil may be disposed separately for combustion of combustible gases from the fermentation.
  • a separate chute for garbage may optionally be arranged in the top of the container.
  • Biological toilet comprising a-container in which excrement and optionally garbage may be brought to accelerated fermentation, comprising an air outlet from the container, a heating element in the form of a closed pipe loop exposed to the air in the container and containing a liquid heat transferring medium and arranged in the container between the material to be fermented and 'a collecting chamber located therebeneath, a corrosion-resistant grid above the pipe loop as support for the material to be fermented, and a thermosiphon pump in the pipe loop to circulate the medium on supply of heat from a heat source which also heats the medium.
  • Toilet according to claim 1 and a shunt connection in the pipe loop in parallel with the pump.
  • Toilet according to claim 1 a portion of the pipe loop extending to a position adjacent the bottom of the container.
  • the container having heat insulated walls in the form of a hollow plastic body filled with hardened foam plastic.
  • Toilet as claimed in claim 1 and means for conducting gas from within the container to said heat source'for combustion in said heat source.
