- Figure 4 is the exploded view in perspective of the temperature confirmation mechanism.
- Figure 5 is the perspective view, which showing operation of the temperature confirmation mechanism.
- the bidet apparatus of the present invention has a valve mechanism which is good operability and which prevents water leakage sufficiently, and a temperature confirmation mechanism which is operated flexibly and which no spray will flow out therefrom even if water pressure is too high.
- the main construction of this valve are an external cylinder, an internal cylinder installed within the external cylinder and a valve core which opens and closes communication between the external and internal cylinders.
- the external cylinder which bath tap and bottom are tightly closed, communicates with a water supply pipe.
- the internal cylinder which only its top is tightly closed, is deposited within the external cylinder.
- a washing water conduction pipe which communicates with spout nozzle, is connected to the internal cylinder.
- the opening bottom end of the internal cylinder is opened or closed by the valve core. Thereby, spout of washing water from the spout nozzle is controlled.
- the washing water which is supplied from the faucet, flows through the external cylinder, the internal cylinder and then the washing water conduction pipe, to spout from the spout nozzle.
- valve core opens the bottom end of the internal cylinder by pushing down the valve shaft.
- the spring presses the valve core up to close the bottom end of the internal cylinder. Since the valve core moves up and down in the same direction as pushing direction of the push button of the bidet, any unreasonable big force is not required for the operation of valve mechanism and the good operability thereof can be obtained. Consequently, the water leakage is prevented by sufficient closure.
- the top of the valve core is shaped as approximately cone, the water pressure presses the valve core toward to closing direction. Too much washing water never spout from the spout nozzle suddenly, even if too big water pressure happen to be taken by such as surge of washing water.
- the temperature confirmation mechanism is provided on a pipe which communicate with washing water conduction pipe, such as a branched pipe by a three way change-over valve.
- the temperature confirmation mechanism comprises a hollow portion formed around the peripheral surface of a pipe at least in part, a closing member in the shape of a tube and a temperature checking hole provided on the closing member. The hollow portion is closed by the closing member and then a chamber is made around the pipe. A communication hole is provided to communicate the inside of said pipe and said chamber.
- the diameter of the temperature checking hole is bigger than the diameter of the communication hole.
- the water pressure from the temperature checking hole reduces, since hot water spout from the temperature checking hole after hot water flow into the chamber from the inside of the pipe. Whereby, hot water is prevented to spray from the temperature checking hole to outside.
- the temperature checking hole can be in all radial, because the closing member is deposited as to rotate around the chamber.
- the temperature checking hole can be at proper position for any type of faucet. Thereby, its flexible operation is available.
- a spout hose can be extended from this temperature checking hole to a hand of the user. Therefore, where a change-over valve, such as two-way valve or three-way valve, which has the temperature confirmation mechanism of this invention is installed, even if at any faucet, the spout of hot water can be arranged in the most desire position which a user easily uses. Thereby, the temperature of hot water can be efficiently confirmed before spout from the spout nozzle of the bidet.
- a bidet apparatus of the present embodiment is provided to supply washing water from a main pipe 4 of faucet to a bidet 1 via a water distribution pipe 5 and a branch pipe 6.
- a temperature confirmation mechanism 3 is deposited on water distribution pipe 5.
- Water is controlled with a change-over valve 41 to supply to water distribution pipe 5.
- a bidet 1 comprises a grip section 11, a spout nozzle 13 which spouts washing water and is fitted on the free end of grip section 11, a push button 12 which controls flow rate of washing water, a water supply pipe 14 connected to faucet 40, a valve mechanism 2 which controls flow rate from water supply pipe 14 by the operation of push button 12, and washing water conduction pipe 15 which communicates with valve mechanism 2 and spout nozzle 13.
- valve mechanism 2 comprises an external cylinder 21 which communicates with water supply pipe 14, an internal cylinder 22 which communicates with washing water conduction pipe 15, a valve core 23 which controls flow rate of washing water by contacting to the bottom end of internal cylinder 22, a valve shaft 24 connecting to push button 12 to press down valve core 23, and a spring 25 which presses valve core 23 upwardly to close the bottom end of internal cylinder 22.
- Both top and bottom of external cylinder 21 are tightly closed and internal cylinder 21 is installed therein.
- the bottom end of internal cylinder 22 is opening and its top is tightly shut.
- the communication between external cylinder 21 and internal cylinder 22 is controlled by up-down movements of valve core 23.
- valve core is shaped as approximately cone and close internal cylinder 22 in the manner that upper portion of valve core 23 sink into inside of internal cylinder 22.
- O-ring 24a is provided between valve shaft 24 and internal cylinder 22.
- O-ring 21a is provided between grip section 11 and bottom end of external cylinder 21.
- the temperature confirmation mechanism 3 comprises a hollow part 32, in shape of a ring, which formed around the periphery surface of the water distribution pipe 5, a closing tube 35 as closing member which closes hollow part 32 to form a chamber 33, a temperature confirmation port 36 which is formed side-wall of closing tube 35 and spout hot water from chamber 33, a spout pipe 37 which is connected to temperature confirmation port 36 for connection of an extended hose 38, and a communicating hole 31 which is provided for communication between inside of water distribution pipe 5 and chamber 33.
- the diameter of temperature confirmation port 36 and diameter of spout pipe 37 is formed to be bigger than the diameter of communicating hole 31.
- water distribution pipe 5 is inserted into closing tube 35, and closing tube 35 is positioned in the manner that both O-ring 34 stick to inside wall thereof. Thereby, hollow part 32 is closed tightly and chamber 33 is formed.
- the spout pipe 37 is connected to temperature confirmation port 36.
- the branch pipe 6 is connected to supply pipe 3 and secured with a cap 61.
- the temperature of water is confirmed with the temperature confirmation mechanism 3, before washing water is supplied to a bidet 1.
- hot water 7 is supplied into water distribution pipe 5.
- the hot water 7 flows via communicating hole 31 into chamber 33, and spout from the spout pipe 37 after chamber 33 is filled with.
- the hot water 7 always flows and spout from spout exit 37a via chamber 33 and then its water pressure is reduced. Accordingly, even if high water pressure is taken in water distribution pipe 5 suddenly, hot water 7 will never spray because of the above pressure reduction.
- closing tube 35 can rotate around chamber 33 freely (360 degrees) maintaining tight close of chamber 33 thereby, and spout pipe 37 can be turned to any radiation. Therefore, the most suitable direction of spout pipe 37 is selected in depended on the type of water supply equipment, and then the extended hose 38 is connected to it.
- washing water is controlled by valve mechanism 2 of bidet 1.
- washing water flows into external cylinder 21 via water supply pipe 14.
- valve core 23 closes bottom end of internal cylinder 22 and water route from external cylinder 21 is shut. Therefore, the washing water does not flow into washing water conduction pipe 15 in this stage.
- valve core 23 is pressed down by push button 12 and valve shaft 24 pushed down, and valve core 23 releases bottom end of internal cylinder 22. Whereby, washing water flows into washing water conduction pipe 15 from external cylinder 21 via internal cylinder 21.
- valve core 23 moves in the same direction as the pressing direction of push button 12 in the flow rate control, good operability and sufficient closure of valve are achieved.
- valve core 23 The action by water pressure works the valve core 23 to close internal cylinder 22, since the upper portion of valve core 23 is formed approximately cone which diameter gradually becomes attenuate upwardly. Therefore, with the synergism of this shape of valve core 23 and resiliency of spring 25, water leakage should be more efficiently prevented.
- valve core 23 moves to closing direction. This movement prevents to spout too much water from spout nozzle 13.
- valve core 23 Even if the shape of valve core 23 has been changed by secular change, tightness of valve mechanism will be maintained because upper portion of valve core 23 sink into internal cylinder 22 gradually.
- valve core 23 is formed as cone in the above embodiment.
- this invention is not limited by this shape of valve core23.
- Valve core which is formed becoming attenuate gradually for the top, such as whole conical shape, curved surface and so on, could be applicable to obtain same effects.
- the present invention achieve the following effects.
