Description

The present invention is directed to an incineration toilet comprising a security system for controlling an electric motor operating an incineration chamber hatch covering an opening of an incineration chamber. The incineration chamber hatch is prevented from being opened in the event the lid is in the open position or the temperature in the incineration chamber is above a threshold value. BACKGROUND Incinerating toilets are self-contained waterless systems that do not require being hooked up to a sewer system or inground septic system. They rely on electric power or natural or propane gas to incinerate human waste to sterile clean ash. The incineration toilet burns biological waste at high temperatures, leaving only an insignificant quantity of ash. The waste is burned in an enclosed incineration chamber, and the incineration gases are expelled through a separate ventilation pipe. The incineration toilet may comprise a pouch bowl for holding a waste pouch, and an incineration chamber with a hatch arranged below the pouch bowl for receiving the waste pouch into the incineration chamber. The hatch being openable manually or by an electric motor. The pouch bowl further comprises an openable flap synchronized with the openable hatch such that when the hatch is opened, the flap is opened simultaneously such that the waste pouch can fall into the incineration chamber. The flap may comprise a hook device arranged to cooperate with a mating head arranged on the incineration chamber hatch, such that when the hatch opens, the mating head pulls the hook such that the flap opens in the same operation. Inside the incineration chamber, the waste pouch containing biological waste are burned into ashes. Publication EP 3001938B1 discloses an incineration toilet comprising a pouch bowl comprising a flap, and an incineration chamber located below the pouch bowl, comprising an incineration chamber hatch. The hatch and the flap are synchronised such that when the hatch opens, the flap opens simultaneously such that the waste pouch can de deposit into the incineration chamber. The incineration process burns waste into ashes at very high temperatures and for this reason the incineration chamber should be properly isolated and arranged such that the user don't have access to the inside of the incineration chamber. To avoid harm to the user, the incineration chamber needs to be properly sealed by the incineration chamber hatch so that heat or flames don't stand out from the incineration chamber. In addition, the toilet needs a proper safety system that prevents the user to open the incineration chamber hatch when the incineration process is ongoing. The term “incineration process” means that the burner or heating element is active. The objective of the present invention is therefore to provide a safety system to avoid harm or injury to the user when using the toilet. Another objective is to provide a safety system that prevents the incineration chamber hatch from being opened during use., i.e., when the user sitting on the toilet. SUMMARY OF THE INVENTION The present invention is directed to an incineration toilet comprising a security system comprising a security control system and one or more sensors, and wherein the security control system controls the opening and closing of the incineration chamber hatch based on input from the one or more sensors. The invention is directed to an incineration toilet comprising a pouch bowl for holding a waste pouch, and an incineration chamber with an incineration chamber hatch arranged below the pouch bowl for receiving the waste pouch for incineration. The incineration chamber hatch being openable by an electric motor. The pouch bowl comprises an openable flap synchronized with the openable incineration chamber hatch such that when the electric motor opens the hatch, the flap is opened simultaneously such that the waste pouch can fall into the incineration chamber. The incineration toilet comprises a lid for covering a top opening of the pouch bowl, the lid is operable between an open position in which the top opening of the pouch bowl can receive waste, and a closed position in which the top opening is closed and cannot receive waste. The incineration toilet further comprises a security system. The security system comprising a security control system, and one or more sensors for reading the position of the lid and for measuring the temperature in the incineration chamber, and wherein the security control system controls the electric motor such that the hatch is prevented from being opened when the lid is in the open position and the temperature in the incineration chamber is above a threshold value. The lid is referred to a toilet cover and used to keep the toilet safe when it's not being used. The lid is moveable between an open position in which the toilet top opening is open and the toilet can be used, and a closed position where the lid is closing the top opening to prevent small items
