초록 ▼

A method of controlling an operation of a toilet system on-board an aircraft is disclosed. The toilet system includes a toilet bowl, a fluid valve controlling input of fluid into the toilet bowl, a flush switch configured to be activated by a user, and a controller configured to operate the fluid valve. The method includes detecting an activation of the flush switch, monitoring a flush switch activation time period, and determining whether the flush switch activation time period exceeds a preset threshold time period. In response to determining that flush switch activation time period does not exceed the preset threshold time period, a standard flush cycle is initiated. In response to determining that the flush switch activation time period exceeds the preset threshold time period, a maintenance mode is initiated allowing a larger volume of fluid to fill the toilet bowl for maintenance.

대표청구항 ▼

1. A toilet bowl system for use on-board an aircraft, the system comprising: a toilet bowl body comprising a toilet bowl and a shroud;a fluid valve configured to control the flow of fluid into the toilet bowl;a flush switch configured to be activated by an input from a user;a controller configured to control the operation of the fluid valve; wherein the controller, upon detecting activation of the flush switch in a first sequence comprising activation of the flush switch for a regular mode flushing time period, controls the fluid valve to introduce a first amount of fluid into the toilet bowl to a first preset level in the toilet bowl for a first period of time; andthe controller, upon detecting activation of the flush switch in a second sequence different from the first sequence, the second sequence comprising activation of the flush switch for a maintenance mode flushing time period that is longer than the regular mode flushing time period, controls the fluid valve to introduce a second amount of fluid into the toilet bowl to a second preset level in the toilet bowl for a second period of time, the second preset level higher than the first preset level. 2. The system of claim 1, wherein the first period of time is shorter than the second period of time, and the first amount of fluid is less than the second amount of fluid. 3. The system of claim 1, wherein the second sequence of activation of the flush switch comprises alternatively pressing and releasing the flush switch a preconfigured number of times. 4. The system of claim 1, further comprising: a sensor positioned at a rim portion of the toilet bowl, wherein the controller is configured to close the fluid valve when a fluid level in the toilet bowl is a predetermined distance away from the sensor. 5. The system of claim 1, wherein the controller is configured to close the fluid valve after at least one of i) the second period of time has elapsed or ii) the second amount of fluid has been introduced into the toilet bowl. 6. A method of controlling an operation of a toilet system on-board an aircraft, the toilet system including a toilet bowl, a fluid valve controlling input of fluid into the toilet bowl, a flush switch configured to be activated by a user, and a controller configured to operate the fluid valve, the method comprising: detecting an activation of the flush switch;monitoring a flush switch activation time period;determining whether the flush switch activation time period exceeds a preset threshold time period;in response to determining that flush switch activation time period does not exceed the preset threshold time period, initiating a standard flush cycle and controlling the fluid valve to allow fluid input into the toilet bowl for a first period of time to a first preset level in the toilet bowl; andin response to determining that the flush switch activation time period exceeds the preset threshold time period, initiating a maintenance mode, whereinin the maintenance mode, the controller is configured to control the fluid valve to allow fluid input into the toilet bowl for a second period of time to a second preset level in the toilet bowl, the second period of time being longer than the first period of time, the second preset level higher than the first preset level.
