Sanitary toilet seat

Abstract

An energy saving and intelligent electronic sanitary seat comprises a hinge base, a seat portion, a temperature controlling unit, a germicidal device, a control unit, a sensing unit, a hydroelectric unit and a thermoelectric unit. The seat portion includes an upper and lower seat plates. Said germicidal device consists of a plurality of light emitting diodes (LEDs) which can emit ultraviolet light, a ventilation system and a photocatalytic layer. Said sensing unit comprises of two infrared sensors and two pressure monitoring devices. The hydroelectric unit consists of a first and second hydroelectric generators provided respectively about an inlet and outlet of a water tank of a toilet.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a sanitary device, more specifically, a sanitary toilet seat which can be mounted onto a water closet.DESCRIPTION OF PRIOR ART[0002]A water closet or a flush toilet is a common sanitary device for disposing human waste. Conventional flush toilet consists of a toilet bowl, a tank and a toilet seat. When using the toilet, the seat is lowered for supporting the bottom of the user. The toilet seat is usually made of plastic, thus under cold weather user will feel unpleasant chill sensation by sitting on the plastic toilet seat. To eliminate said defect, electronic or computerized toilet seat has been introduced, the seat is supplied with electricity to heat the toilet seat. However, without possibility to detect human presence, the toilet seat has to be heated continuously, which cause the waste of the energy. Besides than the energy waste, toilet seat is usually considered as a medium for transmitting diseases, especially for...

AI Technical Summary

Benefits of technology

[0003]To achieve foregoing objectives, an energy saving electronic sanitary toilet seat is realized by having a toilet seat incorporating a temperature controlling unit, a germicidal device, and a hydroelectric unit. The temperature controlling unit is controlled by a control unit which connects to a sensing unit. Said temperature controlling unit maintains the toilet seat in a minimum temperature when is not used and the sensing unit is an infrared sensor that can activate the temperature controlling unit through the control unit when sensing the approach of user, heating the seat in a short period to avoid unnecessary waste of energy. The heat generated by said temperature controlling unit to warm the toilet seat when is not used can be transformed into electricity through a thermoelectric unit. Further a hydroelectric unit is provided inside the water tank of the toilet to produce power when flushing the toilet. Electricity generated by said thermoelectric unit and hydroelectric unit is stored in an electric power accumulator to reduce power consumption of the present invention.

[0004]As for the hygienic purpose, the germicidal device comprises of multiples ultraviolet light emitting diodes (UVA LEDs), a ventilation device and a photocatalytic layer; the UVA LEDs emit ultraviolet light to sterilize hazardous germs, and said germicidal effect is improved by the photocatalytic layer applied within the ventilation device, thus external air is drawn into the system passing said photocatalytic layer and discharging sterile air, generating circulation cycle to eliminate germs and bacteria efficiently.

[0006]1. Temperature controlling unit operated by a control unit can maintain toilet seat in an adequate temperature, avoiding overheating which burns the user.

[0007]2. UVA LEDs and photocatalytic layer applied within said ventilation system provide dual-sterilizing effect, reducing germs and bacteria to eliminate surface cross infection.

[0008]3. The infrared sensor can detect human's approach and pressure monitoring device can determine whether the seat is actually utilized. Both sensors assist the control unit and allow the toilet seat to function more accurately.

[0009]4. The present invention include can generate alternative power using a hydroelectric unit and a thermoelectric unit to transform the flushing water and heat that warms the toilet seat into valuable energy and achieving energy saving.

Problems solved by technology

The toilet seat is usually made of plastic, thus under cold weather user will feel unpleasant chill sensation by sitting on the plastic toilet seat.

However, without possibility to detect human presence, the toilet seat has to be heated continuously, which cause the waste of the energy.
