Incineration toilet with safety system
An incineration toilet includes 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 is openable by an electric motor. The pouch bowl includes an openable bowl flap synchronized with the openable incineration chamber hatch such that when the electric motor opens the incineration chamber hatch, the bowl flap opens simultaneously such that the waste pouch can fall into the incineration chamber. The incineration toilet further includes 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 is open and can receive waste, and a closed position in which the top opening is closed and cannot receive waste. The incineration toilet further includes a security system including a security control system, and one or more sensors. The one or more sensors are arranged for reading the position of the lid and for measuring the temperature in the incineration chamber. The security control system controls the electric motor such that the incineration chamber hatch is prevented from being opened when the temperature in the incineration chamber is above a threshold value and the lid is in the open position.
1 . 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,
wherein the pouch bowl comprises an openable bowl flap synchronized with the openable incineration chamber hatch such that when the electric motor opens the incineration chamber hatch, the bowl flap opens simultaneously such that the waste pouch can fall into the incineration chamber,
the incineration toilet further 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 is open and can receive waste, and a closed position in which the top opening is closed and cannot receive waste,
wherein the incineration toilet further comprises a security system comprising:
a security control system, and
one or more sensors,
wherein the one or more sensors are arranged for reading the position of the lid and for measuring the temperature in the incineration chamber;
wherein the security control system controls the electric motor such that the incineration chamber hatch is prevented from being opened when the temperature in the incineration chamber is above a threshold value and the lid is in the open position,
wherein the one or more sensors is an inductive sensor arranged for reading the position of the lid,
wherein the inductive sensor is located below the toilet seat and arranged to detect a magnet situated in the lid to read the position of the lid,
wherein, in the event the inductive sensor detects the magnet, information that the lid is in the closed position is sent to the control system, wherein the control system further allows the electric motor to run such that the incineration chamber hatch and the pouch bowl flap can be opened,
wherein, in the event the inductive sensor detects no magnet, information that the lid is in the open position is sent to the control system and the electric motor is not allowed to start.
2 . The incineration toilet according to claim 1 , wherein the one or more sensors is a temperature sensor located in connection with the incineration chamber for measuring the temperature in the incineration chamber.
3 . The incineration toilet according to claim 2 , wherein the temperature sensor is configured to measures the temperature inside the incineration chamber and is configured to send the information to the security control system for comparison with the temperature threshold value.
4 . The incineration toilet according to claim 3 , wherein the temperature threshold value is 90° C., and the security control system prevents the incineration chamber hatch from being opened in the event the temperature in the incineration chamber is above 90° C.
5 . The incineration toilet according to claim 1 , wherein the incineration toilet further comprises a first hatch sensor and a second hatch sensor, and wherein the first hatch sensor and/or the second hatch sensor is arranged for reading the position of the incineration chamber hatch.
6 . The incineration toilet according to claim 5 , wherein the second hatch sensor is arranged to read a closed position of the incineration chamber hatch, and wherein the second hatch sensor communicates with the security control system such that the incineration can start only in the event the incineration chamber hatch is in the closed position.
7 . The incineration toilet according to claim 1 , wherein the incineration chamber comprises an ash tray, and wherein the incineration toilet further comprises an ash tray position sensor arranged to read the position of the ash tray, the ash tray position sensor communicates with the security control system such that the incineration can start only in the event the ash tray is in a predefined position.
8 . The incineration toilet according to claim 1 , wherein the security system comprises a temperature guard device comprising a temperature sensor for reading the temperature on the outside of the incineration chamber, wherein the temperature guard device is a mechanical switch adapted to cut power of a burner/heating element in the event the temperature outside the incineration chamber exceeds a threshold value.
