Converting device for automatic toilet flushing and air deodorizing

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.

Description

THE FIELD AND THE BACKGROUND OF THE INVENTION [0001] This invention refers to improvements of toilet flush systems and, more particularly, to retrofit devices for conversion an usual toilet flush system for the private dwelling to the automatic flush system with control of the flush water quantity and with the air deodorizing in necessary cases. [0002] The water economy is very important in many regions of the planet. It concerns first of all to all big cities and territories with the high population density, including the USA. One way of the water spending is connected with the water closet usage, for as much as for each toilet flushing in the domestic toilets with manual control is being spent from 3 up to 5 gallons of the fresh water. It is desirable to provide an automatic control of the flush water quantity with reduced water quantity for a liquid waste. [0003] It is desirable to create an automatic flush system for use in private dwellings for other reasons as well. Many peopl...

Benefits of technology

[0034] The additional object of the present invention is to create an improved toilet flushing and air deodorizing system, which can be installed at a relatively low cost without using any special tools and skills of the user

Problems solved by technology

Many people experience the temporary or constant difficulties, which can prevent the free pressing of the toilet handle, for example hospitalized persons.

Furthermore, they have no mechanism for the water quantity control and have no deodorizing mechanism.

More by token, two last systems have very complex and expensive control circuits.

Thereby the existing automatic flush systems c
