Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a dual-outlet connecting pipe fitting, a flushing system and a toilet. Background Technology

[0002] Smart toilets typically involve both washing and draining during flushing, powered by a water pump located at the bottom of the tank. Because the pump is at the bottom, an arch often forms in the flushing and drain pipes when connecting them. Therefore, an anti-siphon valve is usually installed at this arched point to prevent water waste due to a siphon effect. In actual use, the water jet from the anti-siphon valve impacting the tank during flushing can produce a loud noise, and the dripping sound can easily give the illusion of a leak, affecting the user experience. Furthermore, the flushing pipe is often quite long, making it prone to colliding with the tank and other components under the impact of the water flow, generating noise. Additionally, there is a lack of restraint within the tank to control the flushing pipe. Utility Model Content

[0003] The purpose of this utility model is to provide a dual-outlet connecting pipe fitting, a flushing system and a toilet, which can prevent the water jet from the anti-siphon nozzle from directly impacting the water in the tank, and can also effectively constrain the flushing pipe and reduce noise.

[0004] To achieve the above objectives, this utility model discloses a dual-outlet connecting pipe fitting, comprising a base, a manifold cavity and two independent connecting pipes on the base, at least one of the connecting pipes having an anti-siphon port, the anti-siphon port connecting the manifold cavity and the cavity of the corresponding connecting pipe; a drain outlet connecting to the outside of the base is provided at the bottom of the manifold cavity. By setting up the manifold cavity, the water flowing out of the anti-siphon port flows out of the base through the drain outlet after being collected, and the impact force of the water flowing out of the anti-siphon port can be greatly reduced before flowing out, which is beneficial for noise reduction.

[0005] Preferably, both connecting pipes are provided with anti-siphon ports, and the manifold is provided with a partition to separate the two anti-siphon ports. By setting the partition, the water jets from the two anti-siphon ports can be prevented from colliding, which helps to reduce noise.

[0006] Preferably, a cover plate is detachably connected to the base, and the cover plate blocks the opening of the manifold. This arrangement can further reduce noise and prevent water from splashing everywhere.

[0007] Preferably, the connecting pipe is arranged in an inverted L-shape, and the anti-siphon port is located at the corner of the connecting pipe. This arrangement facilitates pipe connection and allows the anti-siphon port to function effectively.

[0008] This utility model also discloses a flushing system, which includes a water tank, a water pump assembly, a flushing pipe, and the aforementioned dual-outlet connecting pipe. The water pump assembly is installed at the bottom of the water tank and has a drain outlet and a washing outlet. The base is detachably connected to the upper part of the water tank, and one end of the connecting pipe extends to the outside of the water tank. The anti-siphon port is higher than the working water level of the water tank. The two connecting pipes are a first connecting pipe and a second connecting pipe, and the second connecting pipe has an anti-siphon port. The flushing pipe includes a washing inner pipe, a washing outer pipe, a drain inner pipe, and a drain outer pipe. The washing inner pipe and the drain inner pipe are located inside the water tank, and the washing outer pipe and the drain outer pipe are located outside the water tank. The washing outlet, the washing inner pipe, the first connecting pipe, and the washing outer pipe are connected in sequence, and the drain outlet, the drain inner pipe, the second connecting pipe, and the drain outer pipe are connected in sequence.

[0009] With this setup, the flush pipe can be secured and fixed by the dual-outlet connection fittings, making the flush pipe position more stable and reducing the likelihood of it colliding with the water tank and causing noise. Additionally, the anti-siphon outlet also minimizes noise, enhancing the user experience.

[0010] Preferably, the water tank has an installation port that extends through the inside and outside of the water tank, and the base is connected to the installation port by a thread, a snap-fit, or a screw. This configuration makes the installation of the dual-outlet connection fitting convenient, quick, and secure.

[0011] Preferably, the bottom of the water tank is provided with several positioning posts and a mounting bracket adapted to the water pump assembly, the water pump assembly being placed on the mounting bracket; the water tank is also provided with a limiting member, the limiting member being inserted into the positioning posts and snapped into the inner wall of the water tank; the limiting member and the mounting bracket cooperate to limit the water pump assembly to the bottom of the water tank. With this configuration, the water pump assembly can be installed without screws, eliminating the risk of leakage due to screw penetration, and facilitating assembly.

[0012] Preferably, the water pump assembly includes a pump body, a motor, and an impeller. The pump body has a pump chamber, at least two outlets, and at least one inlet, with the inlet communicating with the pump chamber. The impeller is built into the pump chamber, and the motor drives the impeller to rotate. Both ends of the outlets are open-ended and communicate with the pump chamber. The two outlets are a drainage outlet and a washing outlet, respectively. The drainage outlet faces the direction of water flow when the motor rotates in a first direction, which can be clockwise or counterclockwise. With this configuration, the water flow from the drainage outlet can be controlled by rotating the motor in both directions. When the motor rotates in the first direction, the drainage outlet can discharge a large flow of water, while when the motor rotates in reverse, it discharges a small flow of water or no water at all, making control convenient.

[0013] Preferably, the direction of the washing outlet is the direction of water flow when the motor rotates in the second direction, which is opposite to the first direction. At least the drain outlet and the washing outlet have a secondary outlet, both ends of which are connected and link to the corresponding outlet and the inner cavity of the housing. The connection point between the secondary outlet and the corresponding outlet is located on the side of the outlet closest to the pump chamber. With this configuration, the washing and draining water can be dispensed at different times by controlling the forward and reverse rotation of the motor. That is, when the motor rotates in the first direction, the drain outlet can dispense water at a high flow rate, while the washing outlet dispenses water at a low flow rate or not at all. When the motor rotates in the second direction, the washing outlet can dispense water at a high flow rate, while the drain outlet dispenses water at a low flow rate or not at all.

[0014] In addition, this utility model also discloses a toilet that uses the above-mentioned flushing system.

[0015] This utility model has the following beneficial effects:

[0016] This invention, by incorporating a dual-outlet connecting pipe, constrains the middle section of the flush pipe connecting the water pump assembly and the toilet outlet, resulting in a more stable position and a relatively fixed anti-siphon outlet. Simultaneously, the manifold buffers the water flow from the anti-siphon outlet, effectively reducing noise and improving the user experience. Furthermore, the concealed design of the anti-siphon outlet (covered by a cover plate) prevents water from splashing everywhere, ensuring toilet cleanliness and being more compatible with other electrical components in the toilet.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-14 As shown, this utility model discloses a toilet, which includes a toilet body 10 and a flushing system. The toilet body 10 has a toilet chamber 12 and an equipment installation chamber 11. Several brushing holes are arranged at intervals on the upper part of the wall surface of the toilet chamber 12, and a drain outlet 13 is provided at the bottom of the toilet chamber 12.

[0039] The flushing system includes a water tank 20, a water pump assembly 30, flushing pipes, and dual-outlet connecting fittings 40. The water tank 20 is installed in the device mounting cavity 11 of the toilet body 10. The water tank 20 does not need to completely occupy the device mounting cavity 11; it is best if the water tank 20 is positioned against the device mounting cavity 11 to make room for the installation of other smart accessories for the toilet. The top of the water tank 20 has an overflow port 21 that connects to the toilet bowl cavity 12. Of course, the water tank 20 also has a water inlet, on which a water inlet control valve 22 is installed. This is existing technology and is not the focus of this case, so it will not be described in detail.

[0040] The water pump assembly 30 is installed at the bottom of the water tank 20. Multiple positioning posts 23 and a corresponding mounting bracket 24 are provided at the bottom of the water tank 20. The water pump assembly 30 is placed on the mounting bracket 24, which restricts the horizontal movement of the water pump assembly 30. Additionally, a limiting member 25 is provided in the water tank 20. The limiting member 25 is inserted into the positioning posts 23 (the limiting member 25 has a sleeve 26 that engages with the positioning posts 23), and simultaneously, the limiting member 25 is snapped into the inner wall of the water tank 20 (the limiting member 25 has a hook 27, and the inner wall of the water tank 20 has a groove 28 that engages with the hook 27). The limiting member 25 restricts the upward movement of the water pump assembly 30. The positioning posts 23 guide the installation of the limiting member 25 and contribute to ensuring the stability of its position. To further stabilize the position of the limiting member 25, it can also be connected to the water pump assembly 30, for example, by fitting the limiting member 25 onto the water pump assembly 30. Through the cooperation of the limiting member 25 and the mounting bracket 24, the water pump assembly 30 can be reliably positioned at the bottom of the water tank 20, allowing for screwless installation and simple, convenient assembly.

[0041] The water pump assembly 30 includes a pump body 31, a motor 32, and an impeller 33. The pump body 31 has a pump chamber 34, at least two outlets, and at least one inlet 35, with the inlet 35 connecting to the pump chamber 34. The impeller 33 is housed within the pump chamber 34, and the motor 32 drives the impeller 33 to rotate. Both ends of the outlets are open and connected to the pump chamber 34. Two of the outlets are defined as a drain outlet 36 and a scrubbing outlet 37. The drain outlet 36 faces the direction of water flow when the motor 32 rotates in a first direction, which can be clockwise or counterclockwise. The scrubbing outlet 37 faces the direction of water flow when the motor 32 rotates in a second direction, which is opposite to the first direction. When motor 32 rotates in the first direction, drain outlet 36 can discharge water at a high flow rate, while scrubbing outlet 37 discharges water at a low flow rate or not at all. When motor 32 rotates in the second direction, scrubbing outlet 37 can discharge water at a high flow rate, while drain outlet 36 discharges water at a low flow rate or not at all, thus achieving time-sharing water discharge (low flow rate is considered no water discharge). Of course, by adjusting the angle of scrubbing outlet 37, it is also possible to achieve simultaneous water discharge from drain outlet 36 and scrubbing outlet 37 when motor 32 rotates in the first direction, and high flow rate from scrubbing outlet 37 and low flow rate from drain outlet 36 when motor 32 rotates in the second direction.

[0042] Furthermore, at least the drain outlet 36 and the washing outlet 37 have a secondary outlet 38. Both ends of the secondary outlet 38 are open-ended, and the secondary outlet 38 connects to the corresponding outlet and the inner cavity of the housing. The connection point between the secondary outlet 38 and the corresponding outlet is located on the side of the outlet closest to the connection end of the pump chamber 34. The secondary outlet 38 allows less water to flow into the outlet when no water is needed. By adjusting the orientation and diameter of the drain outlet 36 and the washing outlet 37, whether to add a secondary outlet 38, adjusting the diameter of the secondary outlet 38, and adjusting the speed and direction of the motor 32, various modes of water output control can be achieved, which will not be listed in detail here.

[0043] Of course, the water pump assembly 30 can also be a conventional dual-outlet water pump (i.e., both outlets always discharge water simultaneously), or it can be composed of two single-outlet water pumps. In general, in this case, it is sufficient to ensure that the water pump assembly 30 has two outlets: a drainage outlet 36 and a washing outlet 37.

[0044] The dual-outlet connecting pipe fitting 40 includes a base 41, on which a manifold 42 and two independent connecting pipes are integrally formed. Each connecting pipe has an anti-siphon port 45. Preferably, the connecting pipes are arranged in an inverted L-shape, with the anti-siphon port 45 located at the corner of the connecting pipe. The horizontal section of the connecting pipe is located at the upper end of the base 41, and the vertical section extends to the lower part of the base 41. The anti-siphon port 45 connects the manifold 42 and the corresponding connecting pipe cavity. A partition 46 is also provided in the manifold 42 to separate the two anti-siphon ports 45, preventing the water ejected from the two anti-siphon ports 45 from colliding. A drain port 47, connecting to the outside of the base 41, is located at the bottom of the manifold 42. A cover plate 48 is snap-fitted to the opening of the manifold 42, sealing the opening of the manifold 42. The arrangement of the manifold 42, baffle 46 and cover 48 can effectively buffer the water output from the anti-siphon port 45 and prevent water splashing from the anti-siphon port 45, thus effectively reducing noise.

[0045] The base 41 is detachably connected to the upper part of the water tank 20. Specifically, the water tank 20 has an installation port 29 that extends through the inside and outside of the water tank 20. The base 41 is threaded, snap-fitted, or screwed to the installation port 29. One end of the connecting pipe (i.e., the vertically oriented section of the connecting pipe) extends to the outside of the water tank 20 through the installation port 29. The anti-siphon port 45 is set higher than the working water level of the water tank 20 to ensure its proper function. The drain port 47 on the base 41 is preferably positioned close to the inner wall of the water tank 20 so that the water exiting the drain port 47 can flow down along the inner wall of the water tank 20, avoiding dripping noise.

[0046] The flushing pipe includes an inner flushing pipe 51, an outer flushing pipe 52, an inner drain pipe 53, and an outer drain pipe 54. The inner flushing pipe 51 and the inner drain pipe 53 are located inside the water tank 20, while the outer flushing pipe 52 and the outer drain pipe 54 are located outside the water tank 20. For ease of distinction, the two connecting pipes are defined as the first connecting pipe 43 and the second connecting pipe 44, respectively. The flushing outlet 37, the inner flushing pipe 51, the first connecting pipe 43, the outer flushing pipe 52, and the flushing hole of the toilet body 10 are connected in sequence. The draining outlet 36, the inner drain pipe 53, the second connecting pipe 44, and the outer drain pipe 54, i.e., the sewage outlet 13 of the toilet body 10, are connected in sequence. The inner and outer sections of the flushing pipe are connected and fixed by a double-outlet connecting fitting 40, which effectively constrains the position of the flushing pipe.

[0047] As another implementation, when the pipeline formed by sequentially connecting the washing outlet 37, the washing inner pipe 51, the first connecting pipe 43, the washing outer pipe 52, and the washing hole of the toilet body 10 is not prone to siphon effect, the anti-siphon port 45 on the first connecting pipe 43 can be omitted.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
