Description

DRY TOILET
Field of the invention
The invention relates to a dry toilet as defined in the preamble of independent claim 1. Various dry toilets are known in the art.
Publication WO 90/027720 relates to a composting device for toilet and foodstuff waste to be used in connection with a toilet. In the device according to the invention, the upper portion of a rotating compost container provided with a filtering floor is divided into four sections to keep apart compost materials of different degree of composting. The compost container is positioned partially within the toilet room so that the toilet seat is positioned immediately or substantially immediately above the cover of the composting device. In this way, the natural aeration will not cause the smell of the compost material to enter the toilet room when the cover of the toilet is opened. In the compost container, the waste is aerated both from above and from below. The circulation of air is arranged to take place naturally so that it flows all the time upwards. The air flow causes the liquid on the bottom of the container to evaporate and takes the evaporated liquid with it, thus keeping the above compost material humid. Surplus liquid is discharged from the central area of the bottom of the compost container. This enables the collection of liquid at one point by means of a single-wall rotating container.
Publication EP 2 196 124 presents a composting latrine and a method for maintaining thereof. A problem of latrines in prior art is, among other things, that they require a difficult displacement of the waste from one place to the other, usually outside of the latrine. In the solution according to the invention, the latrine has a space for two containers, one of which is currently for collecting waste and the other is for composting waste. The collecting container can be displaced to composting container's place by displacing inside the space of the latrine. After this, an empty container can be placed in the latrine through the opening in front of the latrine for collecting waste. There is a second opening in the latrine for the removal of the container containing composted waste.
Publication WO 2008/020116 relates to a composting device and a method for composting. The composting device comprises a compost container provided with a feed opening through which waste to be composted is added into the compost container. The compost container comprises a belt loop circulating inside it for the purpose of turning, mixing and/or moving the waste to be composted.
Objective of the invention The object of the invention is to provide a dry toilet which is easy to empty.
Short description of the invention
The dry toilet of the invention is characterized by the definitions of independent claim 1. Preferred embodiments of the dry toilet are defined in the dependent claims.
The axis arrangement provides for easy emptying of the dry toilet because the compost container of the dry toilet can be tilted with respect to a horizontal axis for facilitating the emptying of the compost container.
In a preferred embodiment of the dry toilet all parts attached to the compost container, the container lid, and a possible openable and closable cover for opening a feed opening in the container lid, are fixedly movable attached. This makes parts of the dry toilet difficult to steal or to lend.
