Abstract: Kits and methods for installing a toilet bowl or toilet assembly without tools, and an installed toilet assembly, are described. The methods and assembly work with an existing flange or can include a standard closet flange configured to receive a flange bolt. The kits and assemblies include a flange bolt having a bolt head and a bolt stem extending from the bolt head and having an end portion opposite the bolt head, wherein the stem has an outer surface and the bolt head is configured so as to fit through an opening in a flange so that the bolt head contacts the lower surface of the flange and the end portion of the stem extends upwardly from the upper surface of the flange; and a bolt locking knob having an interior surface defining an opening extending therethrough, wherein the interior surface is configured so that when the end of the bolt stem is placed within the opening the interior surface of the knob contacts the exterior surface of the bolt stem in locking engagement and the knob is able to be hand tightened on the bolt stem when a toilet bowl base is positioned in place over the flange and the bolts have a size that is coordinated with the size of the locking knobs to eliminate the use of tools on installation of the bowl. Handle fasteners for manual tightening may also be included for installation of a tank on the bowl also without the use of tools. Mounting blocks are also described which enable installation while minimizing potential for injury due to suspending a toilet bowl or assembly while aligning the bowl so as to sit on a flange bolt(s).

A flushing water inlet (30) is in fluid communication with the pan bowl (28). An inwardly facing first sidewall (34) extends substantially around the top of the pan bowl (28). A substantially horizontal ledge extends (36) substantially around the bottom of the first sidewall (34). An inwardly facing second sidewall (37) extends substantially around the pan bowl (28) under the horizontal ledge (36). A flushing water flow splitter (38) is substantially adjacent a rearward end of the first sidewall (34), the flow splitter (38) is in fluid communication with the flushing water inlet (30) and has a leftwards outlet (38a) and a rightwards outlet (38b). A flushing water flow balancer (40) is on a frontwards part of the first sidewall (34), the flow balancer (40) including an inwardly facing projection (40a, 40b, 40c) extending vertically through at least part of the height of the first sidewall (34) and being positioned substantially symmetrically in relation to a forward to rearward centerline of the toilet pan (20). The flow balancer (40) includes leftward (40a) and rightward (40b) angled surfaces which meet at an innermost edge (40c) that is substantially aligned with the forward to rearward centerline of the toilet pan (20). The leftward (40a) and rightward (40b) angled surfaces are substantially triangular in shape and taper from a relatively wide lower part to a narrowed or pointed upper part.

Abstract: A drain valve for low-level water tank flushing includes a drain valve body, a low-level washing ring flushing device and a switch assembly. The switch assembly includes a switch element and a switch sheet. The switch element is connected to the switch sheet by using a lifting rod. When the switch element opens a sealing assembly of the drain valve body under the action of an external force, the switch changes a channel between a water inlet and a water outlet from a small opening state to a big opening state.

Abstract: A float rise speed control tank in a flush toilet is formed so that when the flush water level inside a flush water tank rises and the flush water level reaches a window due to supply of flush water into the flush water tank by a water supply device, the inflow into the float rise speed control tank by flush water in the flush water tank from a window formed above the bottom edge part of the float causes the rise speed of the flush water level in the float rise speed control tank to increase more than the rise speed of the flush water in the flush water tank.
