Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a bathroom accessory, especially to a quick siphon toilet. 
       BACKGROUND OF THE INVENTION 
       [0002]    Spray siphon type toilets accounts for more percentages in the existing market. A flushing type toilet, as figured in  FIG. 1 , the toilet body  1 ′ has a flush waterway  11 ′ and a spray waterway  12 ′, the bottom of the toilet body  1 ′ is disposed with a siphon washing-out pipe  13 ′. The toilet body  1 ′ is usually assembled with a flush water tank  2 ′, the water tank  2 ′ is disposed with an inlet mechanism and a drain valve  21 ′, the inlet mechanism is connected to an inlet pipe, the drain valve  21 ′ is connected to the spray waterway  11 ′ and the flush waterway  12 ′ respectively. Water divides to two part from the drain valve  21 ′ of the water tank  2 ′, one part of the water flows out of the flush waterway  12 ′ to wash the washing surface of the toilet body  1 ′, the other part of the watery flows out of the spray waterway  11 ′ to wash the bottom portion of the toilet body  1 ′ and it also assists the siphon washing-out pipe  12 ′ to form siphon. As the flushing hole of the flush waterway  12 ′ is connected to the air outside, after the flushing of the water to the toilet body  1 ′, under the work of the atmosphere, only the part of the bottom portion of the toilet body  1 ′ under the water seal surface has water, the pipe between the water seal surface and the drain valve  21 ′ is full of air. When the drain valve  21 ′ starts draining, water firstly fills the pipe, then flows out of the flushing hole of the flush waterway  12 ′. As the water of the pipe is not continuous in the initial of draining, the water flow rate of the spray waterway  11 ′ is lower than the condition that the pipe is full of water. The siphon pipe can not form siphon quickly in the initial of draining, resulting in a waste of water. 
       SUMMARY OF THE INVENTION 
       [0003]    The object of the present invention is to overcome the disadvantages of the existing known technology and provide a quick siphon toilet. 
         [0004]    The technical proposal of the present invention is that: 
         [0005]    A quick siphon toilet, comprising a toilet body and a water tank, the toilet body is disposed with a spray waterway to wash the bottom portion of the toilet body and a flush waterway to wash the wall of the toilet body, the bottom portion of the toilet body is disposed with a siphon washing-out pipe, the water tank is disposed with a drain valve, wherein the drain valve is disposed with a first drain outlet connected to the flush waterway and a second drain outlet connected to the spray waterway, the spray waterway is disconnected to the flush waterway. 
         [0006]    In another preferred embodiment, a check valve is disposed between the first drain outlet and the flush waterway, the check valve is disposed with a first state and a second state: the first state is a state that when the water tank drains, the check valve is open, so that water enters the flush waterway through the first drain outlet, at the same time, water of the water tank enters the spray waterway through the second drain outlet; the second state is a state that when the water tank does not drain, the check valve is closed, so that the spray waterway and the flush waterway are separated in sealing way. 
         [0007]    In another preferred embodiment, the water tank is further disposed with an overflow pipe, the drain valve is connected to the flush waterway through the first drain outlet and then the overflow pipe, a check valve is disposed between the first drain outlet and the overflow pipe, the check valve is disposed with a first state and a second state: the first state is a state that when the water tank drains, the check valve is open, so that water enters the flush waterway through the first drain outlet and the overflow pipe, at the same time, water of the water tank enters the spray waterway through the second drain outlet; the second state is a state that when the water tank does not drain, the check valve is closed, so that the spray waterway is separated from the flush waterway and the overflow pipe in sealing way. 
         [0008]    In another preferred embodiment, a check valve is disposed in the flush waterway, the check valve is disposed with a first state and a second state: the first state is a state that when the water tank drains, the check valve is open, so that water enters the flush waterway through the first drain outlet, at the same time, water of the water tank enters the spray waterway through the second drain outlet; the second state is a state that when the water tank does not drain, the check valve is closed, so that the spray waterway is separated from the flush waterway in sealing way. 
         [0009]    The present invention has advantages as follows: 
         [0010]    The quick siphon toilet has the drain valve with a drain inlet, a first drain outlet connected to the flush waterway and a second drain outlet connected to the spray waterway, the spray waterway is separated from the air outside, every time after the flushing, the toilet has pre-saved water for next time&#39;s flushing the bottom portion of the toilet body, when flushing starts at the next time, it does not need water of the water tank to fulfill the spray waterway again. In the present invention, siphon happens quickly, at the same time, the water diversion volume of the flushing hole at the protruding edge of the toilet is increased. In a condition of same water volume, the present invention has longer flushing time and better washing-out effect. And the present invention uses less water based on well flushing function, thus making it water-saving.
