Aircraft oven with safety operation mode
An aircraft oven is provided that includes an inner cavity configured to receive at least one hazardous item, an oven door. When the oven door is closed, the aircraft oven is configured to switch from a normal operation mode to a safety operation mode, in use.
1 . An aircraft oven comprising:
an inner cavity configured to receive at least one hazardous item, the inner cavity surrounded by insulation on a top side, a bottom side, a first lateral side, a second lateral side, and a rear side;
an oven door;
a vent hose disposed through at least one of the top side, the bottom side, the first lateral side, the second lateral side, and the rear side; and
a control valve coupled to the vent hose;
wherein, when the oven door is closed, the aircraft oven is configured to switch from a normal operation mode in which the aircraft oven is operable as an oven for cooking or warming of meals to a safety operation mode, in use,
wherein, when the oven door is closed, an airtight seal is formed between the insulation and the oven door,
wherein, when the aircraft oven is in the normal operation mode, the control valve is configured to allow a fluid flow through the vent hose and the control valve is operable to maintain the aircraft oven as operable as the oven for the cooking or the warming of meals, and
wherein, when the aircraft oven is in the safety operation mode, the control valve is closed so as to prevent the fluid flow through the vent hose.
2 . The aircraft oven of claim 1 , further comprising:
a Human Machine Interface and/or a mechanical actuator;
wherein the Human Machine Interface and/or the mechanical actuator is configured to switch the aircraft oven from the normal operation mode to the safety operation mode, in use.
3 . The aircraft oven of claim 1 , further comprising:
insulation, an airtight seal, wherein the airtight seal is located between the oven door and the insulation.
4 . The aircraft oven of claim 3 , wherein the oven door includes an inner door surface and wherein the inner cavity includes an inner cavity surface and wherein the airtight seal is located between the inner door surface and the inner cavity surface.
5 . The aircraft oven of claim 4 , wherein the inner door surface and the inner cavity surface include a refractory or metallic material.
6 . An aircraft comprising the aircraft oven of claim 1 .
7 . A method for switching an aircraft oven from a normal operation mode to a safety operation mode, the method comprising:
opening an oven door;
depositing at least one hazardous item within an inner cavity of the aircraft oven, the inner cavity surrounded by insulation on a top side, a bottom side, a first lateral side, a second lateral side, and a rear side, wherein a vent hose is disposed through at least one of the top side, the bottom side, the first lateral side, the second lateral side, and the rear side, and wherein a control valve is coupled to the vent hose;
closing the oven door and locking the oven door;
forming an airtight seal between the insulation and the oven door;
activating a user interface to switch from a normal operation mode in which the aircraft oven is operable as an oven for cooking or warming of meals to a safety operation mode,
wherein, when the aircraft oven is in the normal operation mode, the control valve is configured to allow a fluid flow through the vent hose and the control valve is operable to maintain the aircraft oven as operable as the oven for the cooking or the warming of meals, and
wherein, when the aircraft oven is in the safety operation mode, the control valve is closed so as to prevent the fluid flow through the vent hose.
8 . The method of claim 7 , further comprising removing at least one meal carrier from the aircraft oven between the steps of opening the oven door and depositing the at least one hazardous item within the inner cavity of the aircraft oven.
9 . The method of claim 7 , further comprising adding a fire extinguishing agent into the inner cavity between the steps of depositing the at least one hazardous item within the inner cavity of the aircraft oven; and
wherein the fire extinguishing agent is at least one of fire-extinguishing granules and/or an automatic fire extinguisher.
10 . The method of claim 7 , further comprising closing a valve when switching from the normal operation mode to the safety operation mode.
11 . The method of claim 10 , wherein the valve is electrically closed and/or mechanically closed.
12 . The method of claim 7 , wherein a warning signal is provided when the aircraft oven is in the safety operation mode.
13 . The method of claim 7 , wherein a status of the inner cavity is displayed on the aircraft oven.
