Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to a siphon toilet. Background Technology

[0002] In the scenario of toilet replacement in older residential areas, due to the differences in the distance between the drain holes in different houses, the mainstream solution in the market is to use toilets with adjustable drain holes that have an internal hollow design and a displacement device to adapt to diverse replacement needs. These products typically eliminate the drain pipe and use detachable multi-section curved pipes to form the drain channel, and all adopt a washdown flushing structure, which has become the main technical approach to meet the replacement needs of older houses.

[0003] However, existing technologies have many shortcomings that urgently need to be addressed: First, the core ceramic body of the product, due to its internal hollow design and the installation of the offset device, does not possess the independent sewage discharge and flushing functions of a complete toilet, relying entirely on external accessories such as the offset device to achieve its core functions; second, the multi-section bend pipe connection structure is prone to leakage due to poor sealing, and the detachable bend pipe solution requires a fixing position on the ceramic body, which is subject to uncontrollable deformation during the firing process, while the solution with an adjustable offset device in the latter half of the pipe will cause installation interference due to the ceramic body pipe sagging; third, all existing adjustable pit distance solutions that rely on offset devices are only suitable for floor-mounted installations, and cannot meet the diverse replacement needs of wall-mounted installations in older housing areas, thus limiting their applicability. Utility Model Content

[0004] The main purpose of this utility model is to overcome the shortcomings of existing toilets, such as the ceramic body not having an independent sewage discharge function, the risk of leakage due to the connection of multiple bends in the pipes, and the fact that they are only suitable for floor drain scenarios. This utility model proposes a siphon toilet with an independent siphon sewage discharge function, which can meet the dual installation requirements of wall drain and floor drain, and enhance the structural stability of the sewage pipe.

[0005] The present invention adopts the following technical solution:

[0006] A siphon toilet includes a bucket body with a connected toilet bowl and a drain pipe. The bottom of the bucket body has a receiving space corresponding to the area of ​​the toilet bowl and the drain pipe. The drain pipe adopts a siphon structure, and its outlet extends in the front-back direction to near the rear side of the bucket body. The receiving space of the bucket body also has a first support member, which is connected to the drain pipe to support the drain pipe.

[0007] The outlet of the sewage pipe is located near the rear side of the barrel; the two sides of the first support member are respectively connected to the inner walls of the left and right sides of the barrel, and the first support member is connected to the sewage pipe near the outlet.

[0008] The first support member is also provided with a first clearance portion, which is an arched structure that is recessed upward from the bottom of the first support member, and the arched structure is provided through the front and rear direction of the barrel.

[0009] The container space of the toilet bowl is also equipped with a second support member. The two sides of the second support member are respectively connected to the inner walls of the left and right sides of the toilet bowl, and the second support member is connected to the toilet bowl near the sewage pipe.

[0010] The second support member is also provided with a second clearance portion, which is an arched structure that is recessed upward from the bottom of the second support member, and the arched structure is provided to run through the front and rear direction of the barrel.

[0011] The barrel is also equipped with connecting plates arranged along the front and rear direction of the barrel. The two ends of the connecting plates are connected to the second support and the first support respectively; the top of the connecting plates is also connected to the sewage pipe.

[0012] The front of the bucket is provided with a double-layered inner wall, which encloses a cavity. A first through hole is provided on the side of the cavity opposite to the bottom of the toilet bowl. A second through hole is provided on the part of the second support near the left and right sides of the bucket, and the second through hole extends into the cavity.

[0013] The sewage pipe has an ascending section and a descending section; one end of the ascending section serves as the water inlet and connects to the bottom of the toilet bowl, while the other end extends upwards to connect with the descending section, and the end of the descending section serves as the water outlet.

[0014] The inner diameter of the sewage pipe gradually decreases along the direction of water flow, and the inner diameter of the sewage pipe outlet is smaller than that of its inlet.

[0015] The sewage pipe is equipped with a connector near the outlet; it also includes a sleeve, which is fitted onto the outlet of the sewage pipe and is detachably and fixedly connected to the connector, and the sleeve has a third through hole to communicate with the outlet.

[0016] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0017] 1. In this utility model, the sewage pipe adopts a siphon structure, which can achieve efficient sewage discharge by relying on the siphon principle; at the same time, the first support member in the accommodating space is connected to the sewage pipe to form a stable support, which effectively enhances the structural stability of the sewage pipe, avoids the potential water leakage caused by pipe deformation during ceramic firing and multi-section connection, and ensures the efficiency of siphon sewage discharge.

[0018] 2. In this utility model, the outlet of the sewage pipe extends along the front-to-back direction to the rear side of the barrel, which meets the space requirements for wall-mounted installation; the two ends of the first support member are connected to the left and right inner walls of the barrel and connected to the stress concentration area of ​​the pipe near the outlet, which can not only specifically counteract the downward trend of the pipe during firing and limit the displacement and shaking during use, but also control the bottom spacing of the barrel and prevent the bottom feet from turning outward and deforming.

[0019] 3. In this utility model, the arched first clearance portion of the first support member and the arched second clearance portion of the second support member are both connected along the front and rear direction of the barrel. The two are connected to form a cooperative clearance space, which provides sufficient installation channels for wall-to-ground accessories, displacement devices, etc., ensuring that the installation of accessories does not interfere with the support structure and is suitable for various replacement scenarios.

[0020] 4. In this utility model, the second support member connects to the left and right inner walls of the toilet bowl and is connected to the toilet bowl near the sewage pipe, providing stable support for the toilet bowl; the connecting plate connects the second support member and the first support member in the front-back direction, and the top is attached to the sewage pipe for support, forming an integrated structure of "double support + horizontal connection", which simultaneously improves the overall deformation resistance of the toilet bowl, sewage pipe and toilet bowl.

[0021] 5. In this utility model, the front part of the barrel is enclosed by a double-layer inner wall to form a cavity. The first through hole of the cavity and the second through hole of the second support member form a through channel, which can directly pass through pipelines such as the spray hole water inlet pipe. There is no need to design an additional secondary water channel. Without affecting the support strength and the installation space of accessories, the ceramic body structure is simplified, the ceramic weight is reduced, and the layout is more concise.

[0022] 6. In this utility model, the sewage pipe is designed with a segmented structure of rising and falling sections, and with a gradually changing inner diameter design from the inlet to the outlet, it can accelerate the water flow speed, strengthen the negative pressure inside the pipe, and form a stable siphon to improve the sewage discharge effect; at the same time, the connecting parts on the outer periphery of the sewage pipe are matched with the detachable sleeve, which can be adapted to the national standard wall drainage pit distance, and can meet various installation needs such as old house renovation without modifying the main structure.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0034] The present invention will be further described below through specific embodiments.

[0035] See Figure 1 A siphon toilet includes a bowl body 20, on which an interconnected toilet bowl 21 and a drain pipe 22 are integrally formed. A receiving space 23 is provided at the bottom of the bowl body 20 corresponding to the area of ​​the toilet bowl 21 and the drain pipe 22, located below them. The drain pipe 22 is an integrated siphon structure, enabling siphon drainage. The outlet 25 of the drain pipe 22 extends along the front-to-back direction to near the rear of the bowl body 20, adapting to connect drain fittings. The receiving space 23 of the bowl body 20 also includes a first support member 30, which is connected to the drain pipe 22 to support it, effectively enhancing the structural stability of the drain pipe 22, avoiding pipe deformation during ceramic firing and the risk of leakage caused by multi-section bends, and further ensuring that the drainage efficiency of the siphon structure is not affected.

[0036] The outlet 25 of the sewage pipe 22 is located near the rear side of the barrel 20, which meets the space requirements for wall-mounted installation. The two ends of the first support member 30 are respectively connected to the bottom inner walls of the left and right sides of the barrel 20, and the first support member 30 is connected to the sewage pipe 22 near the outlet 25, reinforcing the stress-concentrated area of ​​the sewage pipe 22 near the outlet 25. This effectively counteracts the downward tendency of the pipe due to gravity during ceramic firing, preventing pipe deformation, and also limits the displacement and shaking of the sewage pipe 22 during use. Furthermore, the first support member 30 can also control the distance between the left and right sides of the bottom of the barrel 20, preventing the bottom from turning outwards and causing uneven deformation due to excessive hollowing at the bottom during ceramic firing, further ensuring the structural integrity of the ceramic body.

[0037] Furthermore, the first support member 30 and the bottom of the sewage pipe 22 near the outlet 25 are integrally connected by a connecting column 31 to achieve stable support. The first support member 30 is also provided with a first clearance portion 32, which is an arched structure that is concave upward from the bottom of the first support member 30 and runs through the front and rear direction of the barrel body 20. The first clearance portion 32 with an arched structure does not affect the support strength and can reserve sufficient installation space for wall-to-floor accessories or relocation devices, adapting to various replacement needs.

[0038] See Figure 3 The accommodating space 23 of the bucket body 20 is also provided with a second support member 40. The second support member 40 is connected to the inner walls of the left and right sides of the bucket body 20, and is connected to the toilet bowl 21 near the sewage pipe 22, providing stable support for the toilet bowl 21. The second support member 40 and the first support member 30 are arranged correspondingly along the front and rear direction of the bucket body 20, and the left and right sides of the second support member 40 extend upward to the outer top of the toilet bowl 21, forming a plate-like support structure that balances support area and structural strength.

[0039] The second support member 40 is also provided with a second clearance portion 41. The second clearance portion 41 is an arched structure that is recessed upward from the bottom of the second support member 40, and the arched structure runs through the front and rear direction of the barrel body 20. The second clearance portion 41 is opposite to and connected to the first clearance portion 32 to form a cooperative clearance space, providing a smooth passage for the installation of wall-to-ground accessories and long pit distance displacement devices, ensuring that the accessories can be smoothly laid out in the front and rear direction of the barrel body 20 without interfering with the support structure.

[0040] See Figure 3 and Figure 6 The bottom accommodating space 23 of the barrel 20 is also provided with a connecting plate 50 arranged along the front and rear direction of the barrel 20. The two ends of the connecting plate 50 in the front and rear direction are respectively connected to the second support member 40 and the first support member 30. The top of the connecting plate 50 is fitted along the arc of the outer peripheral wall of the sewage pipe 22 and is firmly connected to the bottom of the sewage pipe 22, forming an integrated structure of horizontal connection and vertical support, which improves the overall structure and deformation resistance of the barrel 20; and provides support for the sewage pipe 22, preventing the pipe from sagging or shifting during use, and ensuring the siphon sewage discharge effect.

[0041] The front of the toilet bowl 20 has a double-layered inner wall 60, which is made of single-sided slurry and encloses a cavity 61. A first through-hole 62 is provided on the side of the cavity 61 opposite to the bottom of the toilet bowl 21. A second through-hole 63 is provided on the left and right sides of the second support member 40 near the toilet bowl 20, and the second through-hole 63 extends into the cavity 61, forming a through-channel structure. The jet inlet pipe can be inserted through the second through-hole 63, pass through the cavity 61, and exit through the first through-hole 62, connecting to the drain outlet at the bottom of the toilet bowl 21. This eliminates the need for an additional secondary water channel, simplifying the ceramic structure and reducing its weight, while maintaining support strength and installation space for bottom accessories, resulting in a more streamlined layout.

[0042] The sewage pipe 22 has a siphon-type segmented structure with an upward and downward flow, comprising an integrally formed rising section 221 and a descending section 222. One end of the rising section 221 serves as an inlet 24, connecting to the sewage outlet at the bottom of the toilet bowl 21, while the other end extends upward along the internal space of the bowl 20 to the highest point of the siphon before connecting to the descending section 222. The descending section 222 extends downward along the rear side of the bowl 20, with its end serving as an outlet 25, located near the rear side of the bowl 20.

[0043] The inner diameter of the sewage pipe 22 gradually decreases from the inlet 24 to the outlet 25 along its water flow direction, and the inner diameter of the outlet 25 is smaller than that of the inlet 24, forming a gradually changing flow channel structure. This accelerates the water flow velocity, strengthens the negative pressure within the pipe, creates a stable siphon, and improves the sewage discharge effect. For example, the inner diameter of the inlet 24 is approximately 60 mm, and the inner diameter of the outlet 25 is approximately 45 mm.

[0044] In this embodiment, the vertical distance between the center of the outlet 25 of the sewage pipe 22 and the highest point of the siphon (i.e., the water seal point) is set based on the characteristics of the short pipe structure and the siphon principle, for example, it can be set to about 90mm. In practical applications, the length of the corresponding section of the pipe can be flexibly adjusted according to the target siphon effect, the precision of ceramic body production, or the adaptation requirements of the installation scenario to ensure that a stable negative pressure siphon can be formed under the short pipe structure.

[0045] In practical applications, see Figures 7-9 To meet the national standard pit distance requirements for wall-mounted installations and to ensure installation flexibility and ease of maintenance in old house renovation scenarios, a connector 70 is integrally formed on the outer periphery of the sewage pipe 22 near the outlet 25. It also includes a sleeve 80, which is fitted onto the outlet 25 of the sewage pipe 22 and detachably fixedly connected to the connector 70. A third through hole 81 is provided on the sleeve 80 to communicate with the outlet 25.

[0046] Among them, see Figure 3The connector 70 consists of two perforated components prefabricated and bonded during the blanking stage. They are symmetrically arranged on both sides of the outlet 25, with pre-drilled screw holes to form a stable fixing base. The sleeve 80 is fitted around the outlet 25 of the sewage pipe 22, and one side is connected to the connector 70 by screws, allowing for a detachable and fixed connection. A third through hole 81 is provided on the other side of the sleeve 80. For example, the axial dimension of the sleeve 80 is 45mm, and its outer diameter is approximately 65mm. A third through hole 81 with a diameter of 45mm is provided on one end face of the sleeve 80, with the center of the third through hole 81 offset by 9mm from the center of the outer diameter of the sleeve 80, to fit the pipe flow channel. Regarding the pit distance adaptation, if the wall-to-pit distance of the outlet 25 of the sewage pipe 22 is 170mm, the sleeve 80, when installed, can adapt to a 180mm standard wall-to-pit distance.

[0047] To ensure the sleeve 80 is securely installed at the outlet 25 of the sewage pipe 22 and to facilitate smooth assembly, the distance from the connection point of the connecting column 31 to the outlet 25 of the sewage pipe 22 to the axial dimension of the sleeve 80 is greater than, for example, greater than 45mm. This distance provides sufficient axial installation space for the sleeve 80, preventing interference between the sleeve 80 and the connecting column 31 and surrounding support structures during the locking process between the sleeve 80 and the connector 70.

[0048] When installing the siphon toilet using a wall-mounted system in this embodiment, first determine the toilet's placement based on the location of the drain outlet within the wall, ensuring that the outlet 25 of the drain pipe 22 is aligned with the drain outlet on the wall. Depending on installation requirements, the sleeve 80 can be installed: if it needs to conform to national standard pit spacing or enhance sealing, the sleeve 80 can be fitted around the outlet 25 of the drain pipe 22 and secured with the connecting piece 70 around the outlet 25 using screws; if the sleeve 80 is not required, a seal can be directly installed at the connection between the outlet 25 of the drain pipe 22 and the drain outlet on the wall. Finally, fix the bottom of the toilet bowl 20 to complete the wall-mounted installation.

[0049] When a siphon toilet is installed using a floor drain, if the matching body 80 is already installed, remove it first. Then, insert the wall-to-floor adapter along the through-type clearance of the first support 30 and the second support 40 into the bottom receiving space 23 of the toilet body 20. Seal one end of the wall-to-floor adapter to the outlet 25 of the drain pipe 22, align the other end with the floor drain outlet and seal it. Finally, fix the bottom of the toilet body 20 to complete the floor drain installation.
