Description
- The present application relates to the technical field of sanitary wares, and particularly relates to a low water level toilet.
- At present, most toilets use ceramic materials, and with the increasing popularity and use of the toilets, the amount of generated ceramic waste is also increasing. Therefore, people are increasingly inclined to designs of toilets using less materials, so as to save resources and reduce pollution.
- Reference is made to
FIG. 1 , which is a schematic view showing the structure of a toilet in the conventional technology. - The toilet includes a water storage tank 01, a
toilet bowl 02 and a subsequent sewage drain pipe 07 and so on. - A drain valve is provided in the water storage tank 01, and when the drain valve is opened, water in the water storage tank 01 flows into a common
sub water channel 03, and then flows into a flush-ringwater delivery pipe 04 and a spraying-type, water delivery pipe 0 The flush-ringwater delivery pipe 04 is arranged at a surface of a toilet seat, and the flush-ringwater delivery pipe 04 is provided with flushingholes 041 for flushing thetoilet bowl 02 from top to bottom. One end of the spraying-type water delivery pipe 05 is a spraying opening 051 for flushing a bottom of thetoilet howl 02. Because the water storage tank 01 is required to supply water to the flush-ringWater delivery pipe 04, the water storage tank 01 is required to be designed to have a height above the surface of the toilet seat, so that a working water level of the water storage tank 01 can be ensured to be higher than the surface of the toilet seat, to provide enough potential energy to drive the water to flow into the flush-ringwater delivery pipe 04 to clean thetoilet bowl 02, and to generate siphonage at the same time. However, the higher the water storage tank 01 is, the more the ceramic is used, thus, not only the production costs are increased, the resource consumption and environmental pollution are also increased. - In a case that the water storage tank of the toilet is designed to be flush with the surface of the toilet seat, the consumption of ceramic materials will be greatly reduced. It is estimated that with this design, the consumption of ceramic materials can be reduced about 12 kilograms for one toilet. However, since the working water level of the water storage tank is lower than the surface of the toilet seat, that is, the water in the water storage tank cannot flow into a pipe at the toilet seat to flush the toilet bowl, and with such low potential energy, the sewage drain pipe can hardly generate siphonage.
- Therefore, an issue to be addressed by those skilled in the art is to ensure flushing efficiency while reducing the resource consumption and the production costs.

- It can be seen from the above technical solutions that, in the low water level toilet according to the present application, during a flushing process, the water intake device is connected to a water supply system, and water provided by the water intake device is directly delivered to the flush-ring water delivery pipe through the flush-ring water supply component, and when the, water passes through the ejecting mechanism of the flush-ring water supply component, negative pressure is generated in the ejecting mechanism. Since the ejecting mechanism is in communication with the water storage tank, the water stored in the water storage tank flows into the ejecting mechanism, then flows to the flush-ring water delivery pipe along the flush-ring water supply component, and then flows out from flushing holes in the flush-ring water delivery pipe, to flush downward from the surface of the toilet seat of the toilet bowl. One end of the spraying-type water delivery pipe is in communication with the output end of the drain valve, the drain valve is opened, the water in the water storage tank flows from the water inlet of the spraying-type water delivery pipe into the spraying-type water delivery pipe through the drain valve, then flushes the bottom of the toilet bowl via the water spray opening of the spraying type water delivery pipe, and then is drained out via a sewage drain pipe at the bottom of the toilet bowl. When the flushing process is finished, the drain valve is closed, the, water inlet of the spraying-type water delivery pipe that is in communication with the output end of the drain valve is closed, another end, that is the water spray opening is closed by the water in the toilet howl. Since the spraying-type water delivery pipe is an independent pipe, and the only two openings, that is the water inlet and the water spray opening, are both closed, especially for the water inlet at a relatively high water level, when the drain valve is closed, the water inlet is closed; the water spray opening is closed by the water in the toilet bowl, thus under the atmospheric pressure, the water in the spraying-type water delivery pipe will not flow out from the water spray opening, but fills the spraying-type water delivery pipe, that is, the spraying-type water delivery pipe is filled with water.
- With the above arrangements, a pipeline pressure of the water intake device is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ring water supply component, water is allowed to flow upward, therefore, the position of the bottom surface of the water, storage tank can be effectively lowered. The position of the water inlet of the spraying-type water delivery pipe is lowered, which effectively reduces the height of the spraying-type water delivery pipe in the vertical direction. Thus, in a situation that the lateral dimension of the spraying-type water delivery pipe is unchanged, a path length of the spraying-type water delivery pipe is decreased, which reduces the energy loss in the spraying-type water delivery pipe. When the flushing, process is performed again, because the spraying-type water delivery pipe is filled with water, the water in the spraying-type water delivery pipe directly flushes the bottom of the toilet bowl through the water spray opening, an operation of discharging the air in the spraying-type water delivery pipe is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency The bottom surface of the water storage tank is arranged to be lower than the surface of the toilet seat of the toilet bowl, so that under the condition that the water storage tank has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and the production costs.

- Referring to
FIGS. 2 to 6 ,FIG. 2 is a schematic view showing the structure of a low water level toilet according to a first embodiment of the present application;FIG. 3 is a schematic view showing the low water level toilet in a first state according to the first embodiment of the present application;FIG. 4 is a partially enlarged view of portion A inFIG. 3 ;FIG. 5 is a schematic view showing the low water level toilet in a second state according to the first embodiment of the present application; andFIG. 6 is a partially enlarged view of portion B inFIG. 5 . - A low water level toilet is provided according to an embodiment of the present application, which includes a
toilet body 1, awater intake device 2, adrain valve 3, a flush-ring water supply component 4 and a switching device 5. The toilet body I is provided with a water storage tank 11, atoilet bowl 12, a flush-ringwater delivery pipe 13 and a spraying-type water delivery pipe 14. The flush-ringwater delivery pipe 13 is located near a surface of a toilet seat of thetoilet bowl 12, and is used to flush a peripheral wall of thetoilet bowl 12. The spraying-type water delivery pipe 14 is in communication with both a bottom of the water storage tank 11 and a bottom of thetoilet bowl 12, and is used to flush the bottom of thetoilet bowl 12. Thewater intake device 2, thedrain valve 3 and the flush-ring water supply component 4 are all arranged inside the water storage tank 11. One end of the flush-ring water supply component 4 is in communication with the flush-ringwater delivery pipe 13, and another end of the flush-ring water supply component 4 is in communication with thewater intake device 2. The flush-ring water supply component 4 is provided with an ejecting mechanism in communication with the water storage tank 11. When water flows from thewater intake device 2 to the flush-ringwater delivery pipe 13, negative pressure is generated in the ejecting mechanism, such that water stored in the water storage tank 11 is sucked towards the flush-ringwater delivery pipe 13, - The spraying-type water delivery pipe 14 is independently arranged in the
toilet body 1, and the spraying-type water delivery pipe 14 is provided with only two openings, including a water inlet in communication with an output end of thedrain valve 3 and a water spray opening 141 in communication with the bottom of thetoilet bowl 12. That is, the spraying-type water delivery pipe 14 is a closed pipe, and the only two openings thereof are the water inlet and the water spray opening 141. The water inlet of the spraying-type water delivery pipe 14 is in communication with the output end of thedrain valve 3, and the water spray opening 141 of the spraying-type water delivery pipe 14 is in communication with the bottom of thetoilet bowl 12. - For the low water level toilet according to the embodiment of the present application, during a flushing process, the
water intake device 2 is connected to a water supply system, and water provided by thewater intake device 2 is directly delivered to the flush-ringwater delivery pipe 13 through the flush-ring water supply component 4, and when the water passes through the ejecting mechanism of the flush-ring water supply component 4, negative pressure is generated in the ejecting mechanism. Since the ejecting mechanism is in communication with the water storage tank 11, the water stored in the water storage tank 11 flows into the ejecting mechanism, then flows to the flush-ringwater delivery pipe 13 along the flush-ring water supply component 4, and then flows out from flushingholes 131 in the flush-ringwater delivery pipe 13, to flush downward from the surface of the toilet seat of thetoilet bowl 12. One end of the spraying-type water delivery pipe 14 is in communication with the output end of thedrain valve 3, thedrain valve 3 is opened, the water in the water storage tank 11 flows from the water inlet of the spraying-type water delivery pipe 14 into the spraying-type water delivery pipe 14 through thedrain valve 3, then flushes the bottom of thetoilet bowl 12 via the water spray opening 141 of the spraying-type water delivery pipe 14, and then is drained out via asewage drain pipe 16 at the bottom of thetoilet bowl 12. When the flushing process is finished, thedrain valve 3 is closed, the water inlet of the spraying-type water delivery pipe 14 that is in communication with the output end of thedrain valve 3 is closed, another end (where the water spray opening 141 is located) of the spraying-type water delivery pipe 14 is closed by the water in thetoilet bowl 12. Since the spraying-type water delivery pipe 14 is an independent pipe, and the only two openings (the water inlet and the water spray opening 141) thereof are both closed, especially for the water inlet at a relatively high water level, when thedrain valve 3 is closed (that is, in a non-draining state), the water inlet is closed, thedrain valve 3 seals the water inlet of the spraying-type water delivery pipe 14 to isolate the end of the spraying-type water delivery pipe 14, where the water inlet is located, from the outside air; the water spray opening 141 is closed by the water in thetoilet bowl 12, thus under the atmospheric pressure, the water in the spraying-type water delivery pipe 14 will not flow out from the water spray opening 141, but fills the spraying type water delivery pipe 14, that is, the spraying-type water delivery pipe 14 is filled with water. - With the above arrangements, a pipeline pressure of the
water intake device 2 is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ring water supply component 4, water is allowed to flow upward, therefore, the position of the bottom surface of the water storage tank 11 can be effectively lowered. The position of the water inlet of the spraying-type water delivery pipe 14 is lowered, which effectively reduces the height of the spraying-type water delivery pipe 14 in the vertical direction. Thus, in a situation that the lateral dimension of the spraying-type water delivery pipe 14 is unchanged, a path length of the spraying-type water delivery pipe 14 is decreased, which reduces the energy loss in the spraying-type water delivery pipe 14. When the flushing process is performed again, because the spraying-type water delivery pipe 14 is filled with water, the water in the spraying-type water delivery pipe 14 directly flushes the bottom of thetoilet bowl 12 through the water spray opening 141, an operation of discharging the air in the spraying-type water delivery pipe 14 is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency. The bottom surface of the water storage tank 11 is arranged to be lower than the surface of the toilet seat of thetoilet howl 12, so that under the condition that the water storage tank 11 has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and the production costs. - Further, a top surface of the water storage tank 11 and a top surface of the
toilet bowl 12 lie in a same plane. With the above arrangement, the water storage tank 11 (at least a water surface inside the water storage tank 11) is not required to be higher than the surface of the toilet seat of thetoilet bowl 12. It should be understood that, the height of the water storage tank 11 is not limited by the position of the flush-ringwater delivery pipe 13, thereby facilitating the production of thetoilet body 1, effectively reducing the material consumption of thetoilet body 1, reducing the volume of the low water level toilet, and further facilitating the installation of the low water level toilet. The top surface of the water storage tank 11 may also be higher or lower than the top surface of thetoilet bowl 12. - The ejecting mechanism of the flush-ring water supply component 4 includes an ejecting pipe 41 in communication with the flush-ring
water delivery pipe 13 and awater intake pipe 42 in communication with a water outlet of thewater intake device 2. The ejecting mechanism employs the Venturi principle, as long as a diameter of an end, facing thewater intake pipe 42, of the ejecting pipe 41 is greater than a diameter of an end, facing the ejecting pipe 41, of thewater intake pipe 42, when the water rapidly flows from thewater intake pipe 42 to the ejecting pipe 41, negative pressure is generated, which sucks the water stored in the water storage tank 11 towards the ejecting pipe 41 In this embodiment, the end, facing thewater intake pipe 42, of the ejecting pipe 41 is an outwardly flared opening 411, and an end, inserted into the outwardly flared opening 411, of thewater intake pipe 42 is an inwardly necked,opening 421. The outwardly flared opening 411 cooperates with the inwardlynecked opening 421, to form a Venturi structure. Since the flush-ring water supply component 4 is located inside the water storage tank 11, the outwardly flared opening 411 is in communication with the water storage tank 11. After the water delivered by thewater intake device 2 passes through the inwardlynecked opening 421, the pressure at a joint between the outwardly flared opening 411 and the inwardlynecked opening 421 drops, thus the water in the water storage tank 11 is driven to enter the ejecting pipe 41 from the outwardly flared opening 411, and then flows toward the flush-ringwater delivery pipe 13 together with the water delivered by thewater intake device 2. With the above arrangements, a flush volume of the flush-ringwater delivery pipe 13 is effectively increased. - In this embodiment, an end, opposite to the
water intake pipe 42, of the ejecting pipe 41 is in communication with the flush-lingwater delivery pipe 13 through a connecting hose 43. - Further, the low water level toilet also includes a switching device 5 configured to switch the
water intake device 2 between two states, to allow thewater intake device 2 to be in communication with the flush-ring water supply component 4 or the water storage tank 11. That is, through the switching of the switching device 5, the communication between thewater intake device 2 and the flush-ring water supply component 4 or the communication between thewater intake device 2 and the water storage tank 11 is realized. One end of the flush-ring water supply component 4 is in communication with the flush-ringwater delivery pipe 13, another end of the flush-ring water supply component 4 is in communication with thewater intake device 2, thus in a case that thewater intake device 2 is in communication with the flush-ring water supply component 4, the water delivered out of the water outlet of thewater intake device 2 passes through the flash-ring water supply component 4 and then flows into the flush-ringwater delivery pipe 13; and in a case that thewater intake device 2 is in communication with the water storage tank 11, the water delivered om of the water outlet of thewater intake device 2 flows into the water storage tank 11. By operating the switching device 5, the communication between thewater intake device 2 and the flush-ring water supply component 4 and the communication between thewater intake device 2 and the water storage tank 11 are regulated, which facilitates the regulation of an amount of the water supplied from thewater intake device 2 to the flush-ringwater delivery pipe 13 and the water storage tank 11. - As shown in
FIGS. 7 to 10 , in a first embodiment, the switching device 5 includes a baffle 51 and a rotation shaft 52. The rotation shaft 52 is rotatably arranged on the ejecting pipe 41, the baffle 51 is connected to the rotation shaft 52 and is used for opening or closing an inner channel of the ejecting pipe 41. As shown inFIG. 4 , when the baffle 51 closes the inner channel of the ejecting pipe 41, the water delivered by thewater intake pipe 42 flows into the water storage tank 11 through the opening (the outwardly flared opening 411) of the ejecting pipe 41. As shown inFIG. 6 , when the baffle 51 opens the inner channel of the ejecting pipe 41, the water delivered by thewater intake pipe 42 flows into the flush-ringwater delivery pipe 13 along the ejecting pipe 41. That is, it is only needed to control the rotation shaft 52 to rotate, thus the structure is simple, and the control is convenient - In order to allow the switching device 5 to switch automatically the low water level toilet further includes a linkage device 6 connected to the switching device 5 and the
drain valve 3, and a drain button 8 of the low water level toilet is connected to the linkage device 6. When the drain button 8 is pressed, the linkage device 6 drives the rotation shaft 52 to rotate, and the baffle 51 opens the ejecting pipe 41. - The water level in the water storage tank 11 drops, a buoy of the
drain valve 3 falls, thedrain valve 3 is closed and drives the linkage device 6 to reset, the rotation shaft 52 is no longer limited by the linkage device 6, and thus under the action of the water flow in the ejecting pipe 41, the baffle 51 drives the rotation shaft 52 to rotate to close the ejecting pipe 41. - In this embodiment, the rotation shaft 52 is provided with a switch connecting block 53, the linkage device 6 is provided with a linkage connecting block 61 connected to the switch connecting block 53, and the linkage connecting block 61 is insertedly connected to a connecting slot of the switch connecting block 53. When it is required to flush the toilet, the drain button 8 is pressed, the
drain valve 3 is opened, and one end of the linkage device 6 falls, another end of the linkage device 6 that is provided with the linkage connecting block 61 rises, thereby driving the switch connecting block 53 to move in a trend of moving upward, to allow the rotation shaft 52 to rotate. Taking the direction shown inFIG. 8 as an example, the rotation shaft 52 rotates anticlockwise, to drive the baffle 51 to rotate, thereby opening the ejecting pipe 41.

- Based on the above description of the disclosed embodiments, those skilled in the art are capable of carrying out or using the present application. It is obvious for those skilled in the art to make many modifications to these embodiments. The general principle defined herein may be applied to other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments illustrated herein, but should be defined by the broadest scope consistent with the principle and novel features disclosed herein.
- With the above arrangements, a pipeline pressure of the water intake device is effectively utilized, and in conjunction with the ejecting mechanism of the flush-ring water supply component, water is allowed to flow upward, therefore, the position of the bottom surface of the water storage tank can be effectively towered. The position of the water inlet of the spraying-type water delivery pipe is lowered, which effectively reduces the height of the spraying-type water delivery pipe in the vertical direction. Thus, in a situation that the lateral dimension of the spraying-type water delivery pipe is unchanged, a path length of the spraying-type water delivery pipe is decreased, which reduces the energy loss in the spraying-type water delivery pipe. When the flushing process is performed again, because the spraying-type water delivery pipe is filled with water, the water in the spraying-type water delivery pipe directly flushes the bottom of the toilet bowl through the water spray opening, an operation of discharging the air in the spraying-type water delivery pipe is avoided, thus reducing the energy loss, improving potential energy utilization, and speeding up water pressure transfer, such that the efficiency for generating siphonage is increased, which increases the flushing efficiency. The bottom surface of the water storage tank is &Tanned to be lower than the surface of the toilet seat of the toilet bowl, so that under the condition that the water storage tank has the same volume, the material consumption of the low water level toilet is effectively reduced, thereby reducing the resource consumption and the production costs.
