DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a toilet seat for composting toilets, said toilet seat comprising a seat ring, a bowl space, a bottom hole of the bowl space, and separation means for liquids such as washing water and urine.
Composting toilets of prior art have been equipped with toilet seats containing no facilities for the separation of liquids, whereby urine and other liquids entering the toilet seat have landed into the same space with the bulk to be composted. The composting process is deteriorated thereof due to the excessive moisture content of the bulk and the disturbed balance of the carbon
itrogen ratio by the surplus nitrogen from the urine.
Known in the art are also composting toilet constructions in which the liquids separation means of the toilet seats have been designed to be comprised of relatively simple baffles and similar elements. In these toilet seats a portion of the urine frequently ends up into the bulk to be composted, thus disturbing the composting process. The use of these toilet seats is further hampered by other drawbacks. For instance, urination is possible only in a sitting position. Moreover, the cleaning of the interior surfaces of the toilet seat with water is cumbersome, since the water entering the seat can reach the composting space, therein disturbing the composting process.
It is an object of the present invention to achieve a novel type of toilet seat for composting toilets, said toilet seat being capable of overcoming the drawbacks described above. The toilet seat in accordance with the invention is characterized by having the inside surface of the front part of the bowl space adapted to be at its upper part essentially vertical, at its middle part almost horizontal, and at its lower part convexly curved so that the center part of the curved area is closer to the rear part of the bowl space than the start and end points of the convexly shaped lower part, whereby liquids entering the front part of the bowl space in the toilet seat are conducted along the inside surface of the front part into a separate liquids collecting container, or alternatively, to a treatment process, and by having the liquids separation means formed by a shutter adapted to the lower part of the bowl space or below it.
A preferred embodiment of the toilet seat in accordance with the invention is characterized in that the shutter is transferrable so as to make it possible to close entirely or partially the connection via the bottom hole of the bowl space to the composting space.
Another preferred embodiment of the apparatus in accordance with the invention is characterized in that the shutter is transferrable in the longitudinal direction of the toilet seat between its lowered position under the bowl space and its rear position by means of a transfer mechanism which is connected to the shutter.
A further another preferred embodiment of the apparatus in accordance with the invention is characterized in that the transfer mechanism of the shutter is comprised of lever arms having their one end pivotally connected to the edges of the bowl space and the other end to the shutter; of springs having their one end attached to the shutter and the other end to the edge of the bowl space; and of an operating lever adapted to that end of the lever arms which is at the bowl space side.
The toilet seat in accordance with the invention manages the liquids separation without the need for auxiliary means, whereby the design of the inside surface of the seat bowl acts as the liquids separator. Due to the washing possibility, the toilet seat can be kept hygienic and pleasant to use. Furthermore, the construction achieves the possibilities of urination in the conventional manners, either standing or sitting. Combination of a hand-held shower head with the toilet seat in accordance with the invention extends its use as a bidet.
In the following, the invention will be examined in more detail with the help of a preferred exemplifying embodiment with reference to the attached drawings, in which
FIGS. 1-3 show diagrammatic
