The spout switch valve 523 is used to control the supply of water into the spout 4 to control the opening of either the front spout or the rear spout, ensuring that the front spout and the rear spout are not simultaneously opened.
The mixing valve 522 has a hot water inlet, a cold water inlet, and a warm water outlet. The water outlet of the temperature control valve 51 is directly or indirectly connected with the hot water inlet of the water mixing valve 522 through a water pipe (hose) to realize communication. The cold water inlet end 15 is directly or indirectly connected with a cold water inlet of the water mixing valve 522 through a water pipe (hose) to realize communication. The warm water output from the temperature control valve 522 and the cold water output from the cold water inlet end 15 are mixed in the cavity of the water mixing valve 522 for cooling, and then output from the warm water outlet.
The spout switch valve 523 has one water inlet and more than one water outlet. The water outlet of the mixing valve 522 is directly connected with the water inlet of the spout switch valve 523 or connected through a water pipe (hose). The water outlets of the spout switch valve 523 correspond to the number of spouts 4, and each water outlet of the spout switch valve 523 is connected to one spout 4 through a water pipe (hose) to control the water supply of the spout 4. The warm water outputted from the mixing valve 522 is outputted to the corresponding spout 4 by the spout switching valve 523.
In one embodiment, the temperature control system water valve 52 includes a waterway adapter valve 521 having a hot water line and a cold water line.
The water inlet of the hot water pipeline is communicated with the water outlet of the temperature control valve 51, and the water outlet of the hot water pipeline is communicated with the hot water inlet of the water mixing valve 522.
The water inlet of the cold water pipeline is communicated with the cold water inlet end 15, and the water outlet of the cold water pipeline is communicated with the cold water inlet of the water mixing valve 522.
In this embodiment, the water valve 52 of the temperature control system is provided with a waterway switching valve 521, which has a hot water pipeline and a cold water pipeline that are independent of each other, so that the waterways of the temperature control valve 51, the cold water inlet 15 and the water mixing valve 522 are conveniently switched together. The waterway switching valve 521 may be optionally installed in the rim seat 1.
In one embodiment, as shown in fig. 11-12, the pre-flush system 6 includes a drain valve 61.
The drain valve 61 includes a drain valve water inlet pipe 611, a drain valve water outlet pipe 612, and a drain valve diaphragm 613 for controlling the opening and closing of the drain valve water outlet pipe 612.
The drain valve water inlet pipe 611 is communicated with the hot water inlet end 16, and the drain valve water outlet pipe 612 is communicated with the water inlet end of the spray pipe 4.
The pre-flush system 6 also includes a control mechanism 62 for controlling the opening and closing of the drain valve diaphragm 613.
When the control mechanism 62 is in the initial state, the drain valve diaphragm 613 is in the closed state.
When the control mechanism 62 is in the activated state, the drain valve diaphragm 613 is in the open state.
In this embodiment, the pre-flushing system 6 adopts the drain valve 61 and the control mechanism 62 to realize the pre-flushing function for the spray pipe 4, so that cold water in the spray pipe 4 is flushed out through hot water before the user uses the spray pipe 4, and the spray pipe 4 is filled with hot water. When the user uses the shower head 41, hot water is directly sprayed.
A drain valve 61 is mounted on the bottom plate 11. The drain valve 61 is connected with a drain valve water inlet pipe 611 and a drain valve water outlet pipe 612, and a drain valve diaphragm 613 is arranged in the drain valve 61. The drain valve outlet pipe 612 is connected with the water inlet end of the spray pipe 4 through a water pipe and is used for supplying hot water to the spray pipe 4. The drain valve diaphragm 613 may control the opening and closing of the drain valve outlet 612 to control the supply of water from the drain valve outlet 612 into the spout 4.
The control mechanism 62 may be an electrical or mechanical mechanism. The control mechanism 62 may be activated to control the opening and closing of the drain valve diaphragm 613 and thus the drain valve outlet 612. The control mechanism 62 may directly control the movement of the drain valve diaphragm 613 or indirectly control the movement of the drain valve diaphragm 613. If the control mechanism 62 is an electric control mechanism or a mechanical mechanism, a connecting rod is arranged at the output end of the electric control mechanism or the mechanical mechanism, the drain valve diaphragm 613 is sleeved on the connecting rod, and the connecting rod drives the drain valve diaphragm 613 to act. The control mechanism 62 may also hydraulically actuate the drain valve diaphragm 613.
When the control mechanism 62 is in the initial state, the drain valve diaphragm 613 is in the closed state, and the drain valve outlet pipe 612 is closed.
When the control mechanism 62 is in the triggered state, the drain valve diaphragm 613 is in an open state, and the drain valve outlet pipe 612 supplies hot water into the spout 4 to flush out cold water in the spout 4.
In one of the embodiments, as shown in fig. 2 and 4-13, the seat ring 2 is connected to the ring seat 1 by a pivot shaft 3, and the pivot shaft 3 is movable and adjustable up and down relative to the ring seat 1.
A reset mechanism 32 for driving the pivot shaft 3 to move upwards for reset is arranged between the ring seat 1 and the pivot shaft 3.
The control mechanism 62 includes a first trigger 620, and the pivot shaft 3 is provided with a second trigger 31 for triggering the first trigger 620.
When the seat 2 is in the initial position, the first trigger end 620 is in an initial state.
When seat 2 is in the lowered position, second trigger end 31 triggers first trigger end 620 and places control mechanism 62 in the triggered state.
In this embodiment, the control mechanism 62 includes a first trigger 620. When the first trigger terminal 620 is pressed to trigger, the control mechanism 62 is switched from the initial state to the trigger state.
The seat 2 is movable up and down relative to the seat 1 so that the control mechanism 62 can be activated.
A longer pivot shaft 3 may be disposed at the rear of the seat ring 2 as needed, and a shorter pivot shaft 3 may be disposed at both left and right sides of the rear of the seat ring 2.
The side plates 13 on the left and right sides of the ring seat 1 have adjustment holes 131, and the adjustment holes 131 may be bar-shaped holes or kidney-shaped holes, and the height direction thereof is greater than the front-rear direction thereof. The pivot shaft 3 passes through the adjustment hole 131 with a gap, and the pivot shaft 3 is movable and adjustable up and down in the adjustment hole 131. A second trigger end 31 is mounted on the pivot shaft 3 for triggering the first trigger end 620. The second trigger end 31 may be a slider.
A return mechanism 32 is fitted between the pivot shaft 3 and the ring seat 1, the return mechanism 32 being a spring or an elastic member. When the seat 2 is not under pressure, the return mechanism 32 urges the pivot shaft 3 up the adjustment hole 131 to the top so that the rear of the seat 2 is in a higher position.
In the initial state, i.e. when the seat 2 is not subjected to pressure from the user, the pivot shaft 3 is driven by the return mechanism 32 up to the top of the adjustment hole 131. At this time, the rear end of the seat 2 is at a high position, and the rear end of the seat 2 is not in contact with the rear portion of the toilet main body 7 (ceramic body) with a certain distance therebetween to provide a buffer space.
When a user sits on the seat 2, the seat 2 is pressed and drives the pivot shaft 3 to move downward against the force of the return mechanism 32 until the pivot shaft 3 reaches the bottom of the adjustment hole 131. At this time, the rear end of the seat 2 is at a lower position, and the rear end of the seat 2 is in contact with the rear portion of the toilet main body 7 (ceramic body). The second trigger 31 descends to the lowest position/descent position, and the second trigger 31 triggers the first trigger 620.
Meanwhile, in the process, the reset mechanism 32 provides a certain damping to slow down the falling of the rear end of the seat ring 2, thereby providing a buffer effect, facilitating the user to gradually adapt to the hard contact between the seat ring 2 and the toilet main body 7, and improving the use experience of the user.
In one embodiment, as shown in fig. 4-10, the grommet 1 has a guide groove 17 extending up and down, and the second trigger end 31 is in clearance fit with the guide groove 17.
The first trigger 620 is held in contact with the second trigger 31 and can be depressed by the second trigger 31 to the trigger position.
In this embodiment, the guide groove 17 serves to guide the second trigger end 31 to slide up and down.
The first trigger end 620 can slide up and down, and can be automatically reset to a higher initial position under the action of the reset element.
When the seat ring 2 or the second trigger end 31 is in the initial position, the first trigger end 620 is in the initial position (higher position), and the control mechanism 62 is in the initial state.
When the seat ring 2 or the second trigger end 31 is in the lowered position or the lowest position, the first trigger end 620 is pressed down to the lowered position or the lowest position by the second trigger end 31, and the control mechanism 62 is in the triggered state.
In one embodiment, the top plate 12 has a guide post 121 extending downward, and the second trigger end 31 has a guide hole, and the guide post 121 is clearance fit in the guide hole to guide the second trigger end 31 to slide up and down.
In one embodiment, the drain valve 61 further includes a drain valve relief tube 614, and the control mechanism 62 is coupled to the drain valve relief tube 614.
When the control mechanism 62 is in the initial state, the drain valve pressure relief pipe 614 is in a stopped drain state.
When the control mechanism 62 is in the activated state, the drain valve relief tube 614 is in a drain state.
In this embodiment, the water pressure is used to control the opening and closing of the drain valve diaphragm 613.
The drain valve 61 has an upper water chamber 615 and a lower water chamber 616 therein. The drain valve outlet pipe 612 is installed at the top of the drain valve 61, and a circle of downward extending ribs 617 are arranged at the water inlet of the drain valve outlet pipe 612. The drain valve diaphragm 613 is disposed between the upper water chamber 615 and the lower water chamber 616, and the drain valve diaphragm 613 has a communication hole 6131.
When the drain valve pressure relief pipe 614 does not drain out, after the water in the upper water chamber 615 enters the lower water chamber 616, the water pressure in the upper water chamber 615 and the water pressure in the lower water chamber 616 are balanced gradually, the drain valve diaphragm 613 seals the barrier 617, and the drain valve outlet pipe 612 does not drain.
When the drain valve relief tube 614 drains outwardly, the water pressure in the lower water chamber 616 decreases and the drain valve diaphragm 613 moves downwardly away from the spacer 617 and the drain valve outlet tube 612 drains.
The control mechanism 62 is used to control the drain valve relief tube 614 to drain or to stop draining, and the control mechanism 62 may be a valve structure connected to the drain valve relief tube 614.
When the control mechanism 62 is in the initial state, the drain valve relief tube 614 does not drain and the drain valve outlet tube 612 does not drain.
When the control mechanism 62 is in the activated state, the drain valve pressure relief tube 614 drains and the drain valve outlet tube 612 drains.
Water discharged from the drain valve relief tube 614 may flow through the tube into the seat overflow tube 14 to clean the ceramic body.
Of course, in the present embodiment, the control mechanism 62 may also configure the first trigger terminal 620, which may be triggered by the second trigger terminal 31 in the above embodiment.
In one embodiment, as shown in FIGS. 11-12, the control mechanism 62 includes a water storage valve 621 having a water storage chamber 6211.
The water storage valve 621 is connected to a water storage valve water inlet pipe 623 and a water storage valve water outlet pipe 624 which communicate with the water storage chamber 6211, a water inlet control valve 625 is provided in the water storage valve water inlet pipe 623, and a water outlet control valve 626 is provided in the water storage valve water outlet pipe 624.
The water storage valve inlet pipe 623 communicates with the drain valve pressure relief pipe 614.
When the control mechanism 62 is in the initial state, the water intake control valve 625 is in the closed state, and the water discharge control valve 626 is in the open state.
When the control mechanism 62 is in the triggered state, the water inlet control valve 625 is in an open state and the water outlet control valve 626 is in a closed state.
In this embodiment, the control mechanism 62 employs a water storage valve 621, which has a delay function to extend the drainage time of the drain valve outlet 612.
In this embodiment, the control mechanism 62 includes a water storage valve 621, a water storage valve water inlet pipe 623, a water storage valve water outlet pipe 624, a water inlet control valve 625, and a water outlet control valve 626.
The water storage valve 621 has a water storage chamber 6211 therein, and the water storage valve water inlet pipe 623 and the water storage valve water outlet pipe 624 are respectively communicated with the water storage chamber 6211. A water inlet control valve 625 is installed in the water storage valve inlet pipe 623 for controlling the opening and closing of the water storage valve inlet pipe 623. A drain control valve 626 is installed in the water storage valve drain pipe 624 for controlling the opening and closing of the water storage valve drain pipe 624. The inlet control valve 625 is alternately opened and closed with the drain control valve 626.
The water storage valve water inlet pipe 623 is communicated with the drain valve pressure relief pipe 614, and the water storage valve water inlet pipe 623 and the drain valve pressure relief pipe 614 can be directly connected or indirectly connected through a pipeline.
If the water inlet control valve 625 and the water outlet control valve 626 are solenoid valves, they are controlled by an electric control mechanism in the control mechanism 62. If the water intake control valve 625 and the water discharge control valve 626 are mechanical valves, they are controlled by mechanical mechanisms in the control mechanism 62. When the first trigger 620 is triggered, the electric control mechanism or the mechanical mechanism in the control mechanism 62 is activated to drive the water inlet control valve 625 and the water outlet control valve 626 to be alternately opened and closed.
When the control mechanism 62 is in the initial state, the water inlet control valve 625 is in the closed state, the water storage valve water inlet pipe 623 is closed, the drain valve pressure relief pipe 614 is not drained, the drain valve diaphragm 613 is closed, and the drain valve water outlet pipe 612 is not drained. At this time, the drain control valve 626 is opened and the water in the water storage chamber 6211 is drained to a predetermined low level by the water storage valve drain pipe 624 to prepare for the next water storage. Water discharged from the water storage valve drain 624 may flow through the pipe into the seat overflow pipe 14, cleaning the ceramic body.
When the control mechanism 62 is in the triggered state, the water inlet control valve 625 is in the opened state, the water storage valve water inlet pipe 623 is opened, the drain valve pressure relief pipe 614 is drained, the drain valve diaphragm 613 is opened, and the drain valve water outlet pipe 612 is drained. At this time, the drain control valve 626 is in a closed state to store water for the water storage chamber 6211. When water is stored in the water storage cavity 6211 to a preset high water level, water does not enter the water storage cavity 6211 any more, and the water inlet control valve 625 is closed. In this process, the time for water in the water storage chamber 6211 to be stored from the low water level to the high water level is a delay time, which can be set according to actual needs. The delay time is substantially the drain time of the drain valve outlet 612. The delay time is determined by the volume of the water storage chamber 6211 and the water flow in the water inlet pipe 623 of the water storage valve.
The height, mounting pattern and mounting position of the water storage valve inlet pipe 623 and the water storage valve outlet pipe 624 can be set according to actual needs, and only one or two mounting patterns are shown in the drawings, and do not necessarily represent that they are mounted as such.
Preferably, the water storage valve drain pipe 43 communicates with the bottom of the water storage cavity 411, and the water storage valve inlet pipe 42 communicates with the top of the water storage cavity 411.
In one embodiment, as shown in FIGS. 13-17, the control mechanism 62 further includes a switching valve 622 coupled to the water storage valve inlet conduit 623 and the water storage valve outlet conduit 624.
The switching valve 622 includes a switching valve housing 6220 having a channel 6221 and a switching shaft 6222 in clearance fit with the channel 6221. The switching shaft 6222 can alternately trigger the drain control valve 626 and the inlet control valve 625.
When the switching shaft 6222 is in the initial position, the switching shaft 6222 triggers the drain control valve 626, and the drain control valve 626 is in the open state.
When the switching shaft 6222 is in the trigger position, the switching shaft 6222 triggers the water intake control valve 625, and the water intake control valve 625 is in an open state.
In this embodiment, switching valve 622 employs a switching shaft 6222 to alternately trigger a water inlet control valve 625 and a water outlet control valve 626. The first trigger 620 is disposed at an upper end of the switching shaft 6222 of the switching valve 622, and the switching shaft 6222 is disposed below the second trigger 31. The first trigger 620 may be an end cap or plate, or the first trigger 620 may be directly the upper end of the switching shaft 6222.
The switching valve 622 has a vertically extending passage 6221 therein, with the body portion of the switching shaft 6222 being a clearance fit in the passage 6221. The upper end of the switching shaft 6222 is above the switching valve housing 6220 for being depressed for triggering.
In one assembly, the shift shaft 6222 and the first trigger end 620 may be depressed downwardly to trigger by the second trigger end 31 of the pivot shaft 3 of the race 2 being movable up and down as described above.
In another assembly, the shift shaft 6222 and the first trigger end 620 may be coupled to a handle that is outside of the toilet, and the user may operate the handle to press the shift shaft 6222 and the first trigger end 620.
When the switching shaft 6222 is in the initial position, the upper end of the switching shaft 6222 is in a higher position above the switching valve housing 6220. After the switching shaft 6222 is triggered by pressing, the upper end of the switching shaft 6222 is in a lower position above the switching valve housing 6220.
The switching shaft 6222 has a trigger portion or a driving portion for triggering the water intake control valve 625 and the water discharge control valve 626, and may be a convex portion, a concave portion, a telescopic member, or the like provided on the switching shaft 6222.
The water storage valve inlet pipe 623 and the water storage valve outlet pipe 624 are connected to the switching valve housing 6220, respectively, and communicate with the passage 6221. Thus, when the switching shaft 6222 is moved to the corresponding position, the trigger/drive on the switching shaft 6222 may trigger the inlet control valve 625 or the drain control valve 626. After the inlet control valve 625 is triggered, the inlet control valve 625 opens the water storage valve inlet pipe 623. After the drain control valve 626 is triggered, the drain control valve 626 opens the water storage valve drain 624.
When the switching shaft 6222 is at the initial position, the switching shaft 6222 triggers the drain control valve 626 to open, while the water inlet control valve 625 is not triggered to remain closed, and the water storage chamber 6211 is in the drain state.
When the switching shaft 6222 is pressed to the trigger position, the switching shaft 6222 triggers the water inlet control valve 625 to open, the water inlet control valve 625 is not triggered to remain closed, and the water storage chamber 6211 is in a water storage state.
So arranged, the alternate switching of the inlet control valve 625 and the drain control valve 626 is controlled by the switching shaft 6222 to control the water storage and drain functions of the water storage chamber 6211.
In one of the embodiments, as shown in fig. 13 to 17, a switching shaft resetting member 6223 for driving the switching shaft 6222 to be reset to the initial position is connected between the switching valve housing 6220 and the switching shaft 6222. A switching shaft return member 6223 is connected between the switching shaft 6222 and the top of the switching valve housing 6220 for urging the switching shaft 6222 up to the initial position for return. The switching valve housing 6220 may be a spring.
In one embodiment, as shown in FIGS. 14-19, the inlet control valve 625 includes a first spool valve 6251 and a first return member 6252 for driving the first spool valve 6251 back to a closed state.
The drain control valve 626 includes a second spool valve 6261 and a second return member 6262 for driving the second spool valve 6261 to return to the closed state.
When the switching shaft 6222 is in the initial position, the first spool 6251 is in the closed state and the second spool 6261 is actuated to be opened by the switching shaft 6222.
When the switching shaft 6222 is in the trigger position, the second spool 6261 is in the closed state and the first spool 6251 is actuated to open by the switching shaft 6222.
In this embodiment, the water inlet control valve 625 and the water outlet control valve 626 are both mechanical slide valve structures, which are specifically as follows:
As shown in fig. 18, the inlet control valve 625 includes a first spool valve 6251 and a first return member 6252. The first spool valve 6251 is slidably mounted in the water storage valve inlet conduit 623. A first through hole 6220a is provided on the switching valve housing 6220, and the water storage valve water inlet pipe 623 is connected to the first through hole 6220a so as to communicate with the passage 6221. The water storage valve water inlet pipe 623 has a first stop portion 6233 at one end near the first through hole 6220a, and a seal ring may be disposed on the first stop portion 6233 as needed.
The first spool 6251 includes a thicker first spool body 6251a and a first spool rod 6251b connected to the first spool body 6251a, the first spool rod 6251b extending toward the first through-hole 6220a and being insertable through the first through-hole 6220a. A first stepped portion 6251c is formed at the junction of the first spool rod 6251b and the first spool body 6251 a. When the first spool valve 6251 is in the closed state, the first stepped portion 6251c is sealed in contact with the first stopper portion 6233, thereby closing the water storage valve inlet pipe 623.
The first return member 6252 is connected to the first spool body 6251a for driving the first spool 6251 to move toward the switching valve housing 6220 side so that the opened first spool 6251 can be automatically returned to the closed position. The first return member 6252 may alternatively be a spring.
As shown in fig. 19, the drain control valve 626 includes a second spool valve 6261 and a second return member 6262. A second spool valve 6261 is slidably mounted in the water storage valve drain 624. A second through hole 6220b is provided in the switching valve housing 6220, and the reservoir valve drain 624 is connected to the second through hole 6220b so as to communicate with the passage 6221. The water storage valve drain pipe 624 has a second stopper portion 6243 at one end near the second through hole 6220b, and a seal ring may be disposed on the second stopper portion 6243 as needed.
The second spool 6261 includes a thicker second spool body 6261a and a second spool rod 6261b connected to the second spool body 6261a, the second spool rod 6261b extending toward the second through hole 6220b and being passable through the second through hole 6220b. A second stepped portion 6261c is formed at the junction of the second spool rod 6261b and the second spool body 6261 a. When the second spool valve 6261 is in the closed state, the second stepped portion 6261c is sealed in contact with the second stopper portion 6243, thereby closing the water storage valve drain 624.
The second restoring member 6262 is connected to the second spool body 6261a for driving the second spool 6261 to move toward the switching valve housing 6220 side so that the opened second spool 6261 can be automatically restored to the closed position. The second restoring member 6262 may be a spring.
When the switching valve 622 is in the initial position:
Under the action of the first return member 6252, the first spool rod 6251b extends into the channel 6221 through the first through hole 6220a, the first stepped portion 6251c is sealed in contact with the first stopper portion 6233, and the first spool valve 6251 closes the water reservoir valve inlet pipe 623 and does not supply water to the water reservoir chamber 6211.
The trigger/drive portion of the shift shaft 6222 is in contact engagement with the second spool rod 6261b of the second spool valve 6261 and pushes the second spool rod 6261b back out of the channel 6221 against the force of the second return member 6262 such that the second stepped portion 6261c is separated from the second stop portion 6243, opening the reservoir valve drain 624 and the reservoir chamber 6211 being drainable.
When the switching valve 622 is in the triggered position:
The trigger/drive portion of the shift shaft 6222 is in contact engagement with the first spool slide bar 6251b of the first spool valve 6251 and pushes the first spool slide bar 6251b back out of the channel 6221 against the force of the first return member 6252 such that the first stepped portion 6251c is separated from the first stop portion 6233 opening the water storage valve inlet conduit 623 and the water storage chamber 6211 can store water.
Under the action of the second return member 6262, the second spool rod 6261b protrudes into the channel 6221 through the second through hole 6220b, the second stepped portion 6261c is sealed in contact with the second stopper portion 6243, the second spool valve 6261 closes the water storage valve drain 624, and the water storage chamber 6211 is not drained.
In one embodiment, as shown in fig. 14-19, a first recess 6222a for receiving an end of the first spool valve 6251 and a second recess 6222b for receiving an end of the second spool valve 6261 are provided on the switching shaft 6222 at intervals.
When the switching shaft 6222 is in the initial position, one end of the first spool 6251 is located in the first recess 6222a, and one end of the second spool 6261 is in contact with the circumferential surface of the switching shaft 6222.
When the switching shaft 6222 is in the activated position, one end of the second spool 6261 is located in the second recess 6222b, and one end of the first spool 6251 is in contact with the circumferential surface of the switching shaft 6222.
In the present embodiment, the switching shaft 6222 is provided with a first concave portion 6222a and a second concave portion 6222b at intervals, and the first concave portion 6222a and the second concave portion 6222b may be annular grooves provided on the switching shaft 6222. The first recess 6222a is adapted to receive an end of the first spool 6251 and the second recess 6222b is adapted to receive an end of the second spool 6261.
When the switching shaft 6222 is in the initial position, the first recess 6222a is aligned with the first through-hole 6220a, and the end of the first spool 6251 (i.e., the end of the first spool rod 6251 b) is inserted into the first recess 6222a through the first through-hole 6220 a.
