Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a lavatory, particularly to a wireless data transferring system for a lavatory having sanitary that is capable of providing audio or video service via wireless local area network (WLAN). 
       BACKGROUND OF THE INVENTION 
       [0002]    Toilet or urinal in the marketplace may have an attachment on the drainpipe which prevents the unpleasant odors released into the sewers from returning. Such attachment operates isolate unpleasant odors only after conclusion of the use of the toilet or urinal device, but does not address the odors produced during the use of the toilet or urinal. However, a ventilation system that operates to remove unpleasant odors during the use of the toilet or urinal has not yet been achieved. 
         [0003]    The conventional toilet discharges approximately between 1.6 and 5 gallons of water into the toilet bowl and sewer when it is flushed. Recently, consistent with the recognition of a need for water conservation, toilets have been designed which utilize less volume of water by incorporating water saving devices such as valves which achieve negative buoyancy so that the valve is closed prior to discharge of the entire contents of the toilet tank. However, even with such low water consumption devices, the normal flushing operation will discharge over one gallon of water per flush into the sewer. While this quantity of water may be necessary for flushing some materials such as fecal matter and paper, this quantity of water is in excess of the amount normally required for proper flushing of urine. 
         [0004]    Sensors for the purpose of releasing of flushing processes in urinals are predominantly based on the recognition of a user. Devices with the passive infrared sensors are known, which detect the thermal radiation of human beings in front of the urinal and thereby release the flushing. Some devices with active infrared sensors may emit an infrared signal, which is reflected by the human being in front of the urinal. The reflection signal provides indirectly information if a usage has taken place. Finally, devices with radar sensors could emit microwaves which are reflected by the human being in front of the urinal. 
         [0005]    Furthermore, solid lavatory cleansing blocks are well known in the art. Such blocks are typically designed to release active materials, including fragrance (or perfume), throughout their life. For example ITB (in the bowl) lavatory cleansing blocks are known which are hung from the rim of the lavatory bowl in a conventional container and which are designed to release fragrance and cleansing components upon dissolution of the block when the toilet is flushed. Additionally ITC (in the cistern) lavatory blocks are known for cleansing toilet systems; such block is placed in the cistern so that when the toilet is flushed cleansing components are released with the flush water into the toilet bowl. 
         [0006]    Moreover, currently, toilet, lavatory has above-mentioned development or designs. Therefore, the application and another design of lavatory and lavatory system are provided in the present invention. 
       SUMMARY OF THE INVENTION 
       [0007]    The present invention may achieve the wireless data transferring for lavatory that allows the user watching program or advertisement by employing the identical control unit while using the urinal or toilet. 
         [0008]    The present invention provides a wireless data transferring system for a lavatory comprising a host having a first WLAN module coupled to the data source to transfer data; and at least one sanitary equipment coupled to a receiver, wherein the receiver is coupled to the first WLAN module, and a data output coupled to the receiver to output the data. 
         [0009]    The wireless local area network (WLAN) module includes Bluetooth standard compatible module, Wi-Fi standard compatible module, 802.11x standard compatible module. Data includes audio signal, video signal, digital data and the combination thereof. 
         [0010]    Another aspect of the present invention discloses a lavatory system comprising a host having a processor to process data from a data source, a transmitter coupled to the data source to transfer data; and at least one sanitary equipment coupled to a receiver thereon, wherein the receiver is coupled to the transmitter via a wired transmission line, and a data output coupled to the receiver to output the data.
