Abstract

Abstract A self-contained electric flushing toilet bowl in which water for flushing the bowl is automatically controlled by unique control mechanism to perform a series of cyclic operations in which the supply water to the bowl and outlet flow from the bowl will be so coordinated as to impound a volume of water in the bowl at a raised water level for use in flushing and cleaning the bowl, the control mechanism being housed in an accessible rear compartment of the bowl structure. Outlet flow from the bowl is controlled by means of a valve structure embodied in a line trap of elastomeric material connected to the bowl outlet.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 131 words
In an electric flushing toilet bowl having a top rim opening and a bottom outlet connection with a drain line trap, the improvement comprising: a. means for admitting a flushing fluid to the bowl adjacent the top rim opening, said means having a connection with a fluid source; b. normally closed first valve means for controlling said fluid source connection; c. normally open second valve means for controlling the outlet connection of said bowl; d. manually operable switching means for initiating a flushing operation; and e. means for controlling actuation of said first and second valve means, including electric timing means having an energizing circuit controlled by said switching means and being energizable in response to the operation of said switching means, for effecting a cycle of sequential operations as follows:
Claim 2
Dependent Claim 131 words
In an electric flushing toilet bowl having a top rim opening and a bottom outlet connection with a drain line trap, the improvement comprising: a. means for admitting a flushing fluid to the bowl adjacent the top rim opening, said means having a connection with a fluid source; b. normally closed first valve means for controlling said fluid source connection; c. normally open second valve means for controlling the outlet connection of said bowl; d. manually operable switching means for initiating a flushing operation; and e. means for controlling actuation of said first and second valve means, including electric timing means having an energizing circuit controlled by said switching means and being energizable in response to the operation of said switching means, for effecting a cycle of sequential operations as follows:
Claim 3
Dependent Claim 69 words
to open said first valve means and close the second valve means so as to provide a raised fluid level in said bowl, 2. to open said second valve means in response to the raised fluid level in said bowl so as to utilize the fluid at the raised fluid level in the bowl for flushing the bowl, and 3. after a time interval close the first valve means.
Claim 4
Dependent Claim 69 words
to open said first valve means and close the second valve means so as to provide a raised fluid level in said bowl, 2. to open said second valve means in response to the raised fluid level in said bowl so as to utilize the fluid at the raised fluid level in the bowl for flushing the bowl, and 3. after a time interval close the first valve means.
Claim 5
Dependent Claim 19 words
The improvement according to claim 1, wherein the means to open said second valve means are fluid pressure responsive.
Claim 6
Dependent Claim 163 words
In combination: a. a toilet bowl structure having a top rim opening and a bottom outlet connection; b. a line trap connected with said outlet connection; c. a bowl flushing mechanism including: 1. an outlet control valve in said trap having opened and closed positions with respect to flow through said outlet connection, 2. means operable to supply a predetermined quantity of water to said bowl, when said outlet control valve is in closed position, to raise the normal pool water level in said bowl and impound a volume of water for flushing, whereby upon movement of said outlet control valve to opened position the impounded water will be permitted to flow through the outlet connection and flush the bowl; and d. said trap being of inverted U-shaped configuration and said valve being in the downstream leg of the trap, and said trap being so positioned that, with the valve opened, a low level pool of water will be formed in the bowl.
Claim 7
Dependent Claim 163 words
In combination: a. a toilet bowl structure having a top rim opening and a bottom outlet connection; b. a line trap connected with said outlet connection; c. a bowl flushing mechanism including: 1. an outlet control valve in said trap having opened and closed positions with respect to flow through said outlet connection, 2. means operable to supply a predetermined quantity of water to said bowl, when said outlet control valve is in closed position, to raise the normal pool water level in said bowl and impound a volume of water for flushing, whereby upon movement of said outlet control valve to opened position the impounded water will be permitted to flow through the outlet connection and flush the bowl; and d. said trap being of inverted U-shaped configuration and said valve being in the downstream leg of the trap, and said trap being so positioned that, with the valve opened, a low level pool of water will be formed in the bowl.
Claim 8
Dependent Claim 203 words
In combination: a. a toilet bowl structure having a top rim opening and a bottom outlet connection; b. a line trap connected with said outlet connection; and c. a bowl flushing mechanism including: 1. an outlet control valve in said trap having opened and closed positions with respect to flow through said outlet connection, said outlet valve having means normally urging said valve towards an opened position and said means being electrically energizable for actuation to a closed position, 2. means operable to supply a predetermined quantity of water to said bowl, when said outlet control valve is in closed position, to raise the normal pool water level in said bowl and impound a volume of water for flushing, whereby upon movement of said outlet control valve to opened position the impounded water will be permitted to flow through the outlet connection and flush the bowl, 3. a control circuit for energizing said outlet control valve, and 4. Switching means having normally closed contacts in said control circuit, said switching means being responsive to a raised water level of said pool and being operative to open its contacts so as to deenergize said outlet control valve and permit its movement to opened position.
Claim 9
Dependent Claim 203 words
In combination: a. a toilet bowl structure having a top rim opening and a bottom outlet connection; b. a line trap connected with said outlet connection; and c. a bowl flushing mechanism including: 1. an outlet control valve in said trap having opened and closed positions with respect to flow through said outlet connection, said outlet valve having means normally urging said valve towards an opened position and said means being electrically energizable for actuation to a closed position, 2. means operable to supply a predetermined quantity of water to said bowl, when said outlet control valve is in closed position, to raise the normal pool water level in said bowl and impound a volume of water for flushing, whereby upon movement of said outlet control valve to opened position the impounded water will be permitted to flow through the outlet connection and flush the bowl, 3. a control circuit for energizing said outlet control valve, and 4. Switching means having normally closed contacts in said control circuit, said switching means being responsive to a raised water level of said pool and being operative to open its contacts so as to deenergize said outlet control valve and permit its movement to opened position.
Claim 10
Dependent Claim 14 words
The combination according to claim 4, wherein said switching means are fluid pressure responsive.
Claim 11
Dependent Claim 37 words
The combination according to claim 4, wherein said water supply means includes an electric inlet valve; and including electric timing means having contacts operable to energize and deenergize said outlet control valve and said electric inlet valve.
Claim 12
Dependent Claim 34 words
The combination according to claim 6, wherein the contacts of said timing means are normally open, and in which cam means are operable to close said timing means contacts for a predetermined time interval.
Claim 13
Dependent Claim 41 words
The combination according to claim 7, wherein said timing means includes an electric driving motor having an energizing circuit controlld by said timing means contacts, and including manually operable means for initially closing said timing means contacts to energize said motor.
