  • The traditional toilet device, such as a toilet bowl and a urinal, comprises a flush unit. After the user used toilet device, the flush unit is used to wash out the excreta.
  • For a toilet bowl, the flush unit comprises a tank, a supply pipe set in the tank, a float ball set in the tank and connected with the supply pipe to control the water inflow via the supply pipe, and a flapper valve set in the tank and controlled by a handle set outside the tank via a flush lever to open and close. When the handle is pushed to open the flapper valve, the water in the tank is poured out from a flush pipe which is connected to the tank to wash the toilet bowl and the water level of the tank drops and the float ball drops, then, when the water level is reached a default low level, the flapper valve is closed and the water is poured into from the supply pipe to raise the water level and float ball, finally, the water lever is reached a default high level, the influx of the water from the supply pipe is stopped to wait the next flush.
  • For a urinal, a switch of the flush unit is directly connected with a supply pipe. When the switch is opened, the water is poured into the toilet device via the supply pipe to wash the toilet device. When the switch is closed, the supply pipe is closed to stop to supply water.
  • Furthermore, as we all know that washing hand after use toilet is a common health habit. The wastewater which is produced after user washes his hands is directly drained out without reuse again. However, the wastewater produced by washing hands belongs to clean wastewater to a certain degree. Therefore, if the wastewater produced by washing hands is became as the water for wash out the excreta in the toilet device, the consumption of water is saved.
    • SUMMARY OF THE INVENTION
  • Therefore, the object of the present invention is to provide a water saving toilet device, in which the wastewater is received from a basin to be the cleaning water for washing the toilet after the user used the toilet, resulting in the reuse of the water, achieving the effect of water saving.
  • For the above object, a water saving toilet device comprises a drain pipe of a basin connected with a flush unit of a toilet. The basin is set above the toilet or at the side of the toilet. The basin also comprises a tap for supplying water. Therefore, the wastewater produced after the basin is used is provided into the flush unit of the toilet via the drain pipe to be a washing water for cleaning the toilet after the user used the toilet, achieving the effect of water saving.
  • According to an embodiment, the water saving toilet device further comprises a storage rack, set above the basin or at the side of the basin.
  • According to an embodiment, the toilet is a toilet bowl and the flush unit comprises a tank, a supply pipe set in the tank, a float ball set in the tank and connected with the supply pipe to control the water inflow via the supply pipe, and a flapper valve set in the tank and controlled by a handle set outside the tank via a flush lever to open and close. When the handle is pushed to open the flapper valve, the water in the tank is poured out from a flush pipe which is connected to the tank to wash the toilet bowl and the water level of the tank drops and the float ball drops, then, when the water level is reached a default low level, the flapper valve is closed and the water is poured into from the supply pipe to raise the water level and float ball, finally, the water lever is reached a default high level, the influx of the water from the supply pipe is stopped to wait the next flush.
