Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, specifically a high-flow dual-control vortex flushing system and toilet. Background Technology

[0002] Toilets are ubiquitous bathroom fixtures in daily life. With technological advancements and improved living standards, smart toilets are increasingly favored by consumers. Smart toilets generally refer to intelligent toilet seats. Modern smart toilets utilize various flushing methods, including pump flushing and gravity flushing with a concealed wall-mounted water tank.

[0003] In existing technologies, smart toilets using water pumps rely on a pump to flush. However, in the event of a power outage, the pump stops working and cannot flush. This means that existing water pump toilets have the drawback of being unable to flush and dispose of waste when the power is off.

[0004] Based on this, the present invention provides a high-flow dual-control vortex flushing system and toilet to overcome the problems existing in the prior art. Utility Model Content

[0005] To address the problems mentioned above, this utility model provides a high-flow dual-control vortex flushing system and toilet. When the electric water pump is working normally, the manual control valve is closed. During flushing, water in the second pipe enters the three-way pipe and flows to the nozzle. After passing the nozzle, it flows to the side outlet pipe for flushing. When a power outage occurs and the water pump cannot work normally, but flushing is still required, the manual control valve is opened. Water in the water supply pipe flows through the second and third inlet pipes and into the three-way pipe. After entering the three-way pipe, the water flows to the nozzle and then to the side outlet pipe for flushing. In the event of a power outage and the water pump cannot flush, flushing can be achieved by opening the manual control valve. This system ensures normal flushing and waste removal even during power outages.

[0006] This utility model provides a high-flow dual-control vortex flushing system, including a water tank installed inside the toilet body. The flushing system also includes a water pump. The water pump is connected to the water tank by a first pipe and a second pipe. The second pipe is connected to a T-connector. The T-connector is connected to a nozzle that extends upward into the water tank. The water tank is provided with a side water outlet pipe located above the nozzle. The side water outlet pipe is connected to the side water outlet of the toilet body. The T-connector is connected to a water supply pipe. A manual control valve is installed between the T-connector and the water supply pipe.

[0007] Furthermore, the inlet end of the side outlet pipe is connected to a Venturi tube, which is positioned above the nozzle.

[0008] Furthermore, a first check valve is connected between the tee pipe and the second pipe.

[0009] Furthermore, the water tank body is equipped with an inlet valve body for replenishing water to the water tank. The inlet valve body is connected to the water supply pipe. The water supply pipe is connected to a first inlet pipe. The first inlet pipe is connected to a second inlet pipe. The manual control valve is installed on the second inlet pipe. The second inlet pipe is connected to a third inlet pipe connected to a three-way pipe.

[0010] Furthermore, an air isolation valve is installed on the second water inlet pipe.

[0011] Furthermore, a pressure regulating valve is installed on the second water inlet pipe.

[0012] Furthermore, a second check valve is connected between the three-way pipe and the third inlet pipe.

[0013] Furthermore, the top of the side outlet pipe is provided with an arched bend or a vent hole.

[0014] Furthermore, the side water outlet pipe is connected to a bottom flush pipe, which is connected to the bottom of the toilet body.

[0015] This utility model also provides a toilet, including the flushing system described in any one of the above, wherein the toilet is a wall-mounted toilet or a floor-standing toilet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) When the electric water pump is working normally, the manual control valve is closed. When the water pump is flushing, the water in the second pipe enters the three-way pipe and flows to the nozzle. After passing the nozzle, it flows to the side outlet pipe for flushing. When the water pump cannot work normally due to a power outage and flushing is required, the manual control valve is opened. The water in the water supply pipe flows into the three-way pipe after passing through the second and third inlet pipes. After entering the three-way pipe, the water flows to the nozzle. After passing the nozzle, it flows to the side outlet pipe for flushing. When the water pump cannot flush due to a power outage, flushing can be carried out by opening the manual control valve. It has the effect of normal flushing and sewage discharge even in the event of a power outage.

[0018] (2) When flushing with the water pump or when flushing with the manual control valve, the nozzle is aimed at the venturi tube. By setting the venturi tube, the instantaneous flow rate into the side outlet pipe is increased, causing the water level in the bowl of the toilet to rise instantaneously. Under the action of the vortex water flow, a siphon effect is generated to discharge the waste from the toilet, thus improving the cleaning effect.

[0019] (3) In this application, flushing can be done by flushing a single large flow of water through the side water outlet pipe. The side water outlet pipe can also be connected to a bottom flush pipe. The bottom flush pipe is connected to the bottom of the toilet body. By setting the bottom flush pipe, the side water outlet pipe can be split, with one side running through the side flush and the other side running through the bottom of the toilet body to form a jet siphon flushing method.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The present invention will be described in detail with specific embodiments.

[0028] like Figures 1 to 4As shown, the present invention provides a high-flow-rate dual-control vortex flushing system, including a water tank 2 installed inside the toilet body 1, which is used to store water. The toilet body 1 is provided with a side outlet 11 and a basin 12. When flushing, water flows out from the side outlet 11 and forms a vortex flow along the basin 12 to flush and discharge waste.

[0029] The flushing system also includes a water pump 3. A first pipe 31 and a second pipe 32 are connected between the water pump 3 and the water tank 2. A three-way pipe 4 is connected to the water outlet of the second pipe 32. A nozzle 41 is connected to the vertically upward outlet of the three-way pipe 4. The nozzle 41 extends upward from the bottom of the water tank 2 into the interior of the water tank 2. When the water pump 3 is working, the water in the water tank 2 flows through the first pipe 31 to the second pipe 32 and is sprayed upward through the nozzle 41.

[0030] The water tank 2 is equipped with a side water outlet pipe 21, which is positioned above the nozzle 41. The side water outlet pipe 21 extends upward through the water tank 2 and is connected to the side water outlet 11. During flushing, the water sprayed from the nozzle 41 enters the side water outlet pipe 21, passes through the side water outlet pipe 21, and flows into the pot surface 12 from the side water outlet 11 for flushing and waste removal.

[0031] The water tank 2 is equipped with an inlet valve body 5, which is connected to a water supply pipe 6. After flushing, the water supply pipe 6 fills the water tank 2 with water through the inlet valve body 5. The water supply pipe 6 is connected to a vertically upward first inlet pipe 61, and the top of the first inlet pipe 61 is connected to a second inlet pipe 62. A pressure stabilizing valve 621 and a manual control valve 622 are installed on the second inlet pipe 62. The pressure stabilizing valve 621 stabilizes the water pressure and flow. The manual control valve 622 controls the opening and closing of the second inlet pipe 62. An air isolation valve 623 is also installed on the second inlet pipe 62, and its position is higher than the top of the water tank 2. The air isolation valve 623 connects the second inlet pipe 62 to the atmosphere when the water supply pipe 6 is under negative pressure, effectively preventing water from the water tank 2 from being drawn into the water supply pipe 6.

[0032] The second water inlet pipe 62 is connected to a third water inlet pipe 63. The third water inlet pipe 63 is connected to the side of the tee pipe 4 furthest from the second pipe 32. A first check valve 42 is connected between the tee pipe 4 and the second pipe 32, ensuring that water can only flow from the second pipe 32 side to the tee pipe 4 side. A second check valve 43 is connected between the tee pipe 4 and the third water inlet pipe 63, ensuring that water can only flow from the third water inlet pipe 63 side to the tee pipe 4 side.

[0033] When the electric water pump 3 is working normally, the manual control valve 622 is in the closed state. When the water pump 3 is flushing, the water in the second pipe 32 enters the three-way pipe 4 and flows to the nozzle 41. After passing through the nozzle 41, it flows to the side outlet pipe 21 for flushing. After flushing, water is added to the water tank 2 through the inlet valve body 5. During this process, under the action of the second check valve 43, the water in the three-way pipe 4 cannot flow into the third inlet pipe 63.

[0034] When a power outage occurs and the water pump 3 cannot work properly, and flushing is required, open the manual control valve 622. The water in the water supply pipe 6 flows into the three-way pipe 4 after passing through the second inlet pipe 62 and the third inlet pipe 63. After entering the three-way pipe 4, the water flows to the nozzle 41 and then to the side outlet pipe 21 for flushing. After flushing, water is added to the water tank 2 through the inlet valve body 5. During this process, under the action of the first check valve 42, the water in the three-way pipe 4 cannot flow into the second pipe 32. After flushing, close the manual control valve 622.

[0035] When the water pump 3 fails to flush due to a power outage, flushing can be performed by opening the manual control valve 622, ensuring normal flushing and sewage discharge even during a power outage.

[0036] The inlet end of the side outlet pipe 21 is connected to a Venturi tube 7, which is positioned above the nozzle 41, with the nozzle 41 aligned with the Venturi tube 7. When the flow rate generated by the pump or the dynamic pressure of the water supply pipe 6 is insufficient to produce a vortex flow, the instantaneous flow rate is increased by installing the Venturi tube 7 inside the water tank 2 to satisfy the requirement of generating a vortex flow at the toilet side outlet 11 for flushing and cleaning the toilet.

[0037] When the water pump 3 flushes or the manual control valve 622 is opened, the nozzle 41 is aligned with the venturi tube 7. By setting the venturi tube 7, the instantaneous flow rate into the side outlet pipe 21 is increased, causing the water level in the bowl 12 of the toilet body 1 to rise instantaneously. Under the action of the vortex water flow, a siphon effect is generated, which discharges the waste from the toilet body 1 and improves the cleaning effect.

[0038] In this embodiment, the water pump 3 is a flow stabilizer pump. The flow stabilizer pump can be any existing flow stabilizer pump, which has the function of stabilizing water pressure and water flow.

[0039] An arched bend or vent hole (not shown in the figure) is provided at the top of the side water outlet pipe 21. By providing an arched bend or vent hole on the side water outlet pipe 21, siphoning is prevented from occurring after flushing.

[0040] In this embodiment, flushing can be performed by flushing a single large flow of water through the side water outlet pipe 21. The side water outlet pipe 21 can also be connected to a bottom flush pipe (not shown in the figure). The bottom flush pipe is connected to the bottom of the toilet body 1. By setting the bottom flush pipe, the side water outlet pipe 21 can be split, with one side flowing through the side flush and the other side flowing through the bottom of the toilet body 1 to form a jet siphon flushing method.

[0041] The side outlet 11 of the toilet body 1 is flat, so that the flat water column flushed out by the toilet body 1 adheres to the pot surface 12 to form a vortex for flushing.

[0042] The implementation principle of the high-flow dual-control vortex flushing system provided by this utility model is as follows: When the electric water pump 3 is working normally, the manual control valve 622 is in the closed state. When the water pump 3 flushes, the water in the second pipe 32 enters the three-way pipe 4 and flows to the nozzle 41. After passing through the nozzle 41, it flows to the side outlet pipe 21 for flushing. After flushing, water is added to the water tank 2 through the inlet valve body 5. During this process, under the action of the second check valve 43, the water in the three-way pipe 4 cannot flow into the third inlet pipe 63.

[0043] When a power outage occurs and the water pump 3 cannot work properly, and flushing is required, open the manual control valve 622. The water in the water supply pipe 6 flows into the three-way pipe 4 after passing through the second inlet pipe 62 and the third inlet pipe 63. After entering the three-way pipe 4, the water flows to the nozzle 41 and then to the side outlet pipe 21 for flushing. After flushing, water is added to the water tank 2 through the inlet valve body 5. During this process, under the action of the first check valve 42, the water in the three-way pipe 4 cannot flow into the second pipe 32. After flushing, close the manual control valve 622.

[0044] This utility model also provides a toilet, which includes the aforementioned flushing system. The toilet provided in this application adopts all the technical solutions of the flushing system and has all the advantages of the flushing system, which will not be elaborated here. Correspondingly, the toilet can be a wall-mounted toilet or a floor-standing toilet.

[0045] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
