Converting device for automatic toilet flushing and air deodorizing
First Claim
1. A device for converting of a toilet supplied with a water flush mechanism and handles for manual water quantity option, said device having an electric power supply, a sensing means for detection of user in a toilet using zone and for creation a presence signal, a controller with units for determination a toilet usage duration and for comparison said duration with the first and the second predetermined time intervals to control an executive mechanism, said executive mechanism to actuate the water flush with standard and reduced water quantity depending on said toilet usage duration and a housing for fixing all device units, comprising:
- a) a removable tank with deodorant and a deodorant discharge means, b) said executive mechanism supplied with a reversible electric driver and a control flush mechanism to actuate said handles for manual water quantity option, c) said executive mechanism further supplied with a deodorising mechanism to actuate said deodorant discharge means if said control flush mechanism is actuated for standard flush water quantity, d) a position feedback means for creating a stop signal, when said flush control mechanism has come to an initial position, and for creating a reverse signal, when said flush control mechanism has come to the predetermined reverse position, e) said controller supplied with units for receiving of signals from said sensing means and from said position feedback means, units for processing all signals and units for creating its own control signals for said executive mechanism to discharge said reduced water quantity or to discharge a portion of said deodorant and standard water quantity, said control signals depend on feedback means signals and on toilet usage duration, f) a housing disposed to be able to actuate said toilet handles through said flush control mechanism, herewith said predetermined reverse position corresponds to flushing with reduced water quantity

Abstract
The invention converts a conventional domestic toilet into a system with automatic control of flushing water quantity and air deodorizing without any change of an internal flushing mechanism. A sensing means generates a presence signal, if a user is present in a toilet usage zone. A reversible electric driver actuates the existing toilet flush handle with the flush control mechanism and actuates a deodorant discharge valve with the deodorizing mechanism. A position feedback means defines in what position is located the flush control mechanism. A controller receives and processes the position feedback signals and the presence signals as well and makes the reversible electric driver to move, to stop or to change the movement direction. The invention is applicable for all toilets with pressure-type water flush system and with a water tank system comprising one or two manual flush handles.

18. Method of automatic control of air deodorizing and flushing water quantity based on creation of presence signals, on determination of toilet usage duration and on activation of an executive mechanism for a toilet having a flush mechanism and handles for manual water quantity option, comprising
a) setting and periodical replacement of a tank with a deodorant and a deodorant discharge means b) creation of feedback signals in accordance with the position of said executive mechanism c) creation of control signals for said executive mechanism in accordance with said feedback signals and said toilet usage duration to activate said handles for a reduced water quantity option, if usage duration exceeds the first predetermined time interval, but does not exceed the second predetermined time interval, to activate the handles for a standard water quantity option and said deodorant discharge means, if usage duration exceeds the second predetermined time interval, herewith said reduced water quantity is the quantity necessary to remove a liquid waste, the first predetermined time interval corresponds to the shortest duration necessary for formation of liquid waste in a toilet, the second predetermined time interval corresponds to the shortest duration necessary for formation of solid waste in a toilet.
