Description
Technical Field
The invention relates to the field of bathrooms, in particular to a toilet water supplementing device and method and a siphon toilet.
Background
After the siphonic closestool is flushed, the water level of the trap of the siphonic closestool is lower than the normal water level due to the siphonic effect, and water needs to be supplied to the trap. The water replenishing mode of the common closestool is as follows: after the toilet is flushed, the water inlet valve starts to feed water, most of the water enters the toilet water tank, a small part of the water flows into the drain valve overflow pipe through the water inlet valve water replenishing pipe, the water flowing into the overflow pipe flows downwards along the toilet jet water channel under the action of gravity, and finally flows into the trap, so that the water replenishing of the trap is realized. However, the above-mentioned water replenishing manner of the general toilet is not suitable for a siphon toilet which sprays the water path to reserve water. This is because the water spray channel of such a toilet is still substantially full of water after the flushing process is completed. Because the inside of the water injection channel is in a negative pressure state, if the water replenishing method is adopted, gas can enter the water injection channel, and the water storage state inside the water injection channel is damaged. For this reason, the siphon toilet which sprays the water channel pilot water adopts the following water replenishing method: the water of the water inlet valve water supply pipe is injected into the washing ring water channel, flows out of the washing ring washing hole and flows into the trap along the surface of the toilet bowl. Because the water replenishing flows through the pan surface and is observed by the user, and the water replenishing process usually lasts for a long time (possibly for tens of seconds), the user often mistakenly thinks that water leakage is occurring due to the fault inside the water tank. In addition, after long-time use, the pot surface part that the moisturizing was flowed through can leave yellow incrustation scale, needs often to clear up, influences user experience.

The post-discharge water level refers to the water level of the water tank 5 at the end of the discharge process of the toilet drain valve, and is the lowest water level of the water tank 5 in the one-time flushing process. The diameter of the water replenishing hole 11 is 3-8 mm, and the water replenishing hole is communicated with the toilet water tank 5 and the jet water channel 7 of the toilet in an opening state.

The buoyancy control mechanism comprises a floating body, a linkage piece and a sealing piece used for opening and closing the water replenishing hole 11, the linkage piece is movably arranged on the water replenishing body 1, and the sealing piece and the floating body are respectively arranged on the linkage piece.
In this embodiment, the linkage is a connecting rod 2, the connecting rod 2 is rotatably connected to the water replenishing body 1, and the floating body and the sealing member are respectively disposed at two ends of the connecting rod 2. In other embodiments, the linkage is movably disposed up and down on the supplement.
In this embodiment, the floating body is specifically a floating ball 3, but is not limited thereto, and in other embodiments, the floating body is a buoy, a floater, or the like. The seal is a sealing plate 4, but is not limited thereto. The connecting rod 2 is a bent rod, specifically, the connecting rod 2 is approximately L-shaped, one side of the connecting rod is upward and connected with the floating ball 3, and the bottom of the tail end of the other side of the connecting rod is provided with the sealing sheet 4. Before moisturizing hole 11 opens, one side of connecting rod 2 is vertical state, and the another side is the horizontality, and after moisturizing hole 11 opened, both sides of connecting rod 2 are the tilt state respectively.
In this embodiment, the linkage (i.e. the connecting rod 2) is provided with a limiting portion, when the floating body falls to the lowest position, the limiting portion abuts against the water replenishing body 1, and the limiting portion is specifically a retaining pillar 21, which is arranged at the bottom of the other side of the connecting rod 2 and is far away from the sealing sheet 4.
In this embodiment, the refill body 1 is hermetically connected to the overflow pipe mounting port 611 of the drain valve 6 corresponding to the toilet jet water passage 7. Specifically, the overflow pipe mounting port 611 is located on the base 61 of the drain valve 6, and the drain valve 6 is a flap-type drain valve, but is not limited thereto, and in other embodiments, the drain valve is a cartridge-type drain valve.
In this embodiment, the water replenishing body 1 is a cover, but is not limited thereto. The water replenishing hole 11 is communicated up and down, and the sealing element (namely the sealing sheet 4) is controlled to be opened and closed on the upper side of the water replenishing hole 11. And an annular flange is arranged at the upper end of the water replenishing hole 11 and is used for being correspondingly matched with a sealing element (namely the sealing sheet 4).
The water replenishing device for the toilet can be applied to a siphon toilet for pre-storing water in an injection water channel, and when the device is applied, the water replenishing body 1 is hermetically connected with an overflow pipe mounting opening 611 of a water discharge valve 6 corresponding to an injection water channel 7 (a toilet seat water channel of the siphon toilet corresponds to another water discharge valve which is provided with an overflow pipe communicated with the toilet seat water channel), as shown in fig. 1 and 2.
The working principle of the water replenishing device for the toilet disclosed by the invention is explained in the following by the flushing process of the toilet:
in the initial state, the drainage valve 6 of the toilet is in a closed state, the water tank 5 and the trap 8 of the toilet are in a full water storage state, the floating ball 3 floats in the water tank 5, the buoyancy of the floating ball enables the other side of the connecting rod 2 to have downward pressure, the pressure enables the sealing sheet 4 to press the water replenishing hole 11, the water replenishing hole 11 is kept in a closed state, the water level of the water tank 5 and the negative pressure of the injection water channel 7 also act on the sealing sheet 4, and sealing is strengthened, as shown in fig. 3 and 4;
when the closestool starts to drain, the drain valve 6 is opened, and water in the water tank 5 flows down from the drain port of the drain valve 6 to start flushing; the water level of the water tank 5 is reduced, the buoyancy of the floating ball 3 is reduced, the floating ball 3 starts to fall under the action of gravity, the connecting rod 2 is driven to rotate clockwise for a certain angle, the other side of the connecting rod 2 is tilted, the sealing sheet 4 is driven to leave the water replenishing hole 11, and the water replenishing hole 11 is opened, as shown in figure 5, before the toilet finishes water discharging, the water replenishing hole 11 can discharge water, but the water is not used for replenishing water to the trap 8 of the toilet, but is combined with water discharged from the water discharging port of the water discharging valve 6 for flushing;
when the toilet finishes discharging water, the discharge valve 6 is closed, the water level of the water tank 5 is at the lowest position, namely the water level after discharging, and air cannot enter the injection water channel 7 from the water replenishing hole 11 because the water level after discharging is higher than the height of the water replenishing hole 11; due to the siphoning effect, the water in the trap 8 is sucked away by the siphoning pipeline, so that the water level of the trap 8 of the toilet is very low; the floating ball 3 is completely exposed out of the water surface and falls to the lowest point (the blocking column 21 is abutted to the water replenishing body 1), the rotating angle of the connecting rod 2 is at the maximum, and the water replenishing hole 11 is in the maximum opening state, as shown in fig. 6;
the residual water in the water tank 5 flows into the injection water channel 7 from the water replenishing hole 11, then flows into the trap 8 from the injection port of the injection water channel 7 to replenish the trap 8, and in the process, the water inlet valve of the toilet starts to feed water into the water tank 5, so that the water level of the water tank 5 gradually rises, as shown in fig. 7 and 8; the water replenishing process is continuously carried out, the water level of the trap 8 gradually rises, the water inlet process of the water inlet valve is also continuously carried out, and the water level of the water tank 5 gradually rises; along with the rising of the water level of the water tank 5, the floating ball 3 rises under the action of buoyancy to drive the connecting rod 2 to rotate anticlockwise, so that the other side of the connecting rod 2 falls down to drive the sealing sheet 4 to be close to the water replenishing hole 11, and the opening degree of the water replenishing hole 11 is gradually reduced;
when the water level of the water tank 5 rises to a normal water level, the water inlet valve stops water inlet, the water level of the trap 8 also rises to the normal water level, even overflow occurs, and the overflow water flows away from the siphon pipeline; the floating ball 3 is in a completely floating state, the sealing sheet 4 is pressed against the water replenishing hole 11 by the buoyancy of the floating ball, and the water replenishing hole 11 is kept in a closed state, as shown in fig. 9.
According to the water replenishing device for the closestool, water is replenished to the trap 8 through the water spraying channel 7 on the closestool with water pre-stored in the water spraying channel 7, so that a user cannot observe the water replenishing device, long-flow water scale cannot be formed on the surface of a closestool pan, and the user experience is improved; because the water pressure of the water tank 5 and the negative pressure of the injection water channel 7 exist at the same time, the water replenishing hole 11 only needs a small aperture and is easy to seal; the water replenishing holes 11 are always immersed in water, so that the risk of air entering the injection water channel 7 is avoided; when its water hole 11 that mends is in encapsulated situation, 5 water pressures of water tank and pipeline negative pressure are used on gasket 4, tend to compress tightly gasket 4, strengthen sealed effect, consequently safer.
Referring to fig. 1-9, a toilet according to the present invention, which pre-stores water in a water spray passage 7, includes a toilet refill device according to the present invention.
The flushing and water replenishing processes of the toilet bowl are as described above, and are not described again.
According to the closestool, the water replenishing device disclosed by the invention is used for replenishing water to the trap 8, so that a user cannot observe the water replenishing device and form long-flow scale on the surface of a closestool pan, and the user experience is improved.
Example two
Referring to fig. 10, a toilet water replenishing device of the present invention is different from the first embodiment in that: the water replenishing body 1 is hermetically connected with a mounting opening 51 which is arranged at the bottom of the toilet water tank 5 and communicated with the toilet jet water channel 7. The diameter of the water replenishing hole 11 is 3-7 mm.
The water replenishing principle of the toilet water replenishing device is the same as that of the first embodiment, and the details are not repeated here.
The siphon toilet of the present invention, which pre-stores water in the water injection passage 7, includes the toilet water replenishing device of the present invention as described in the second embodiment.
EXAMPLE III
Referring to fig. 11 to 14, a water replenishing device for a toilet according to the present invention is different from the first and second embodiments in that: the water replenishing body 1 is also provided with a pressure cavity 15 and a water inlet 14, the water inlet 14 and the water replenishing hole 11 are respectively communicated with the pressure cavity 15, and the water inlet 14 is communicated with a water replenishing pipe 20 of the closestool water inlet valve 10. The side wall of the water replenishing body 1 is provided with an installation opening 16, the connecting rod 2 is installed in the installation opening 16 and is in small clearance fit with the installation opening 16 (the size of the clearance is 0.1-0.25 mm, and the size of the clearance cannot change along with the rotation of the connecting rod 2); the sealing disc 8 is located in the pressure chamber 15.
In this embodiment, the mounting opening 16 is provided with a shaft cavity 161 penetrating inside and outside, and the connecting rod 2 is provided with a rotating shaft 22, and the rotating shaft 22 is fitted in the shaft cavity 161. The rotating shaft 22 is a cylindrical shaft in a horizontal state, and the shape of the axial cavity 161 is adapted to the cylindrical shaft, that is, the cavity wall of the axial cavity 161 is a cylindrical surface. Therefore, the connecting rod 2 can rotate smoothly, and the size of the gap between the connecting rod 2 and the water replenishing body 1 can not be changed when the connecting rod 2 rotates. In other embodiments, the rotating shaft is a ball shaft, and the shaft cavity is adapted to the shape of the rotating shaft, that is, the shaft cavity is a ball cavity.
In this embodiment, the water replenishing body 1 includes an upper cover 12 and a lower cover 13, which are connected in a vertical sealing manner, the upper cover 12 is provided with the water inlet 14, the lower cover 13 is provided with the water replenishing hole 11, and the upper cover 12 and the lower cover 13 are matched with each other to form the mounting opening 16.
In this embodiment, the refill body 1 is also hermetically connected to the overflow pipe mounting port 611 of the discharge valve 6 corresponding to the toilet jet water passage 7, but is not limited thereto, and in other embodiments, the refill body is hermetically connected to a mounting port provided at the bottom of the toilet tank and communicating with the toilet jet water passage.
In this embodiment, the diameter of the water replenishing hole 11 is 2-5 mm.
The water replenishing principle of the toilet water replenishing device is similar to that of the first embodiment and the second embodiment, and the difference is that: the water replenishing of the first embodiment and the second embodiment is from the toilet tank 5, and the water replenishing of the third embodiment is mainly from the water replenishing pipe 20 of the water inlet valve 10. The inlet of the water inlet valve 10 is connected with tap water, and the number of the outlets is usually two, one is positioned at the bottom of the water inlet valve 10 and is used for supplying water to the water tank 5, the other is positioned at the top of the water inlet valve 10 and is used for replenishing water, and when the water level of the water tank 5 rises to a normal water level, the water inlet valve 10 stops supplying water to the water tank 5 and also stops replenishing water.
When the pressure of the tap water is high, the water replenishing pipe 20 of the water inlet valve 10 is also in a high-pressure state, so that the pressure of the pressure cavity 15 is increased, and the water replenishing flow of the water replenishing hole 11 is correspondingly increased. The total water replenishing amount is not changed greatly because the water replenishing time is short under high pressure.
When the water pressure of the tap water is low, the water replenishing pipe 20 of the water inlet valve 10 is also in a low-pressure state, so that the pressure of the pressure cavity 15 is reduced, and the water replenishing flow of the water replenishing hole 11 is correspondingly reduced. The water replenishing time is longer at low pressure, so the total water replenishing amount does not change too much.
The actual measurement result shows that the low-pressure water supplement amount can be reduced to 1.2 times of the high-pressure water supplement amount, so that the difference between the low-pressure water supplement amount and the high-pressure water supplement amount is very small.
According to the water replenishing device for the closestool, the pressure cavity 15 and the water inlet 14 are further arranged, so that the water replenishing flow is in direct proportion to the water inlet pressure of the water inlet valve 10, the water replenishing quantity is basically stable, the large change along with the water inlet pressure of the water inlet valve 10 is avoided, and the problem of large high-low pressure water replenishing quantity difference in the first embodiment and the second embodiment is solved. The water replenishing of the first embodiment and the second embodiment is from the water tank 5, the water inlet flow of the water inlet valve 10 is large at high pressure, the water level of the water tank 5 rises quickly, and the water replenishing time is short; at low pressure, the inlet valve 10 has small water inlet flow, the water level of the water tank 5 rises slowly, and the water replenishing time is long. The water replenishing quantity is equal to the water replenishing flow multiplied by the water replenishing time, the water replenishing flow is not changed greatly, but the water replenishing time is greatly different, so that the high-pressure water replenishing quantity is small, and the low-pressure water replenishing quantity is large. The actual measurement shows that the low-pressure water supplement amount can reach 1.8 times of the high-pressure water supplement amount.
According to the water replenishing device for the closestool, due to the fact that the water pressure of tap water and the negative pressure of the injection water channel 7 exist at the same time, the water replenishing hole 11 only needs to be small in diameter, and sealing is easy. When moisturizing hole 11 is in encapsulated situation, 5 water pressures of water tank and the negative pressure of injection water course 7 act on gasket 4, tend to compress tightly gasket 4, strengthen sealed effect, consequently safer.
The siphon toilet of the invention, which pre-stores water in the injection water channel 7, comprises the toilet water replenishing device of the invention as described in the third embodiment.
