Abstract: Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by a sustaining turning moment about its support axis. When water is added, the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, and the tilting bowl moves to a tilted position to discharge its content. As the tilting bowl tilts, the sustaining turning moment is simultaneously reduced to accelerate bowl tilting for efficient discharge of waste to sewage.

Abstract: A gravity drop-toilet uses main water via electronically programmed valves to rinse separate areas of a bowl (71) in sequence via appropriately located and pointing jet orifices (136, 138,140) with about 70% less water than siphon toilets. Electronically timed valve (180) hydraulically causes a pair of bellows (110) to compress and expand and thereby reversibly pivot a mechanical linkage to retain waste in the bowl and drop waste via a vertical waste passageway into a sewer pipe (30). The linkage comprises a transfer arm (118) that pivots a rotating arm of a cup (128) and flap actuating arm (104) to pivot a springy plate (78) upward against a dimple (80) formed on under the side of the flap (30) which thereby aligns itself against the bottom edge (74) of the bowl (71). A urine version of this mechanism uses apertures (174, 175) that they enclose combine to center defecating sitters over a cylinder outlet (48) of the bowl.

Abstract: To eliminate the necessity of a water tank, this invention converts the traditional toilet bowl with siphonic water trap into a toilet basin with a tilting-bowl. The toilet includes a frame, a toilet basin, a tilting bowl and a trigger means. The tilting bowl is mounted to pivot as a movable water/waste container. In its not tilted horizontal position, the tilting bowl receives and holds water/waste delivered to it through the toilet basin. When the tilting bowl tilts, it discharges its content to drainage pipe through a bottom discharge hole; simultaneously allowing water/waste to discharge from basin to drainage. The tilting bowl is normally retarded to stay in its horizontal position by forces applied to the tilting bowl creating a resultant retarding turning moment about its pivot point larger than the turning moment produced by the tilting bowl with its content.

Abstract: A conventional recreation vehicle or caravan toilet, which normally is connected by a simple slide valve to a holding tank mounted below it, can be easily converted to a vacuum toilet at a campground or like stationary site. The holding tank is slid out of the compartment in which it is mounted below the toilet of the recreation vehicle or caravan, and a vacuum adaptor is slid into its place, making a substantially airtight connection with the toilet. The vacuum adaptor is connected up to a substantially stationary vacuum source, such as a below ground vacuum tank at a campground. The vacuum adaptor is preferably connected by a dripless connection to the vacuum source, and includes an arcuately shaped movable valve element that is rotatable about a substantially horizontal axis from a substantially airtight closed position, to an open position, when the toilet is flushed.

Abstract: An assembled toilet bowl mainly includes a seat section, a base and a valve cover set. When activating a flushing control member, the valve cover is opened. The water from the water source will flow through a water incoming passage of the seat section and a bowl-shaped space. Then the water will horizontally flow through a valve port and then flow through a draining passage of the base and downward flow out. Reversely, when the flushing control member is not activated, the valve cover is closed. Under such circumstance, the water of the water source will not flow out and the valve cover will block the valve port to isolate the draining passage. Therefore, the toilet bowl can save more water, can be fixed on a wall, can be easily assembled, and can be easily cleaned.

Abstract: A vacuum toilet system for a vehicle (such as a boat) has numerous advantages.
