Description

Technical Field

[0001] The utility model relates to the technical field of sanitary ware, in particular to a lightweight one-piece toilet. Background Art

[0002] Toilets are generally categorized as two-piece and one-piece, with many differences between them. For example, a two-piece toilet has a separate tank and base; during installation, the tank and base also need to be connected, making them prone to leaks if not installed properly. This also makes cleaning more difficult due to the gap between the base and tank. However, since the tank and base are fired separately, the yield rate is high and the price is low. One-piece toilets, on the other hand, have a tank connected to the base, resulting in a sleek, aesthetically pleasing design. Compared to two-piece toilets, they are simpler, more convenient, and easier to clean. However, since they are fired as a single piece, the yield rate is lower and the price is relatively higher.

[0003] However, one-piece toilets can sometimes be heavier than two-piece toilets because they are typically a single unit and, to maintain structural stability, may use thicker ceramic materials, making transportation and installation more difficult. For example, a one-piece toilet proposed in prior art (Announcement No. CN201080636Y) incorporates a large amount of solid structure in the toilet body to improve overall structural stability, but this has the disadvantage of being heavier. Therefore, reducing the weight of one-piece toilets while maintaining overall structural stability is a pressing technical challenge in the prior art. Utility Model Content

[0004] The utility model provides a lightweight one-piece toilet, which can solve

[0005] This application provides the following technical solutions:

[0006] A lightweight one-piece toilet comprises a toilet body, a water storage tank, a toilet bowl cavity, and a siphon pipe, wherein the toilet body is fixedly connected to the water storage tank, the cross-section of the siphon pipe is square, the siphon pipe comprises a water trap connected to the toilet bowl cavity, a drain bend 1 and a drain bend 2 connected to the water trap in sequence, the water trap being a primary buffer section, the outlet position of the drain bend 1 being lower than the inlet position of the drain bend 2 so that a secondary buffer section is formed between the tail of the drain bend 1 and the head of the drain bend 2; the toilet body also comprises a support block 1 and a support block 2 built into the toilet body, the support block 1 being located as a whole at the bottom of the toilet bowl cavity and fitting the water trap and the front half of the drain bend 1, the support block 2 being located as a whole at the bottom of the drain bend 1 and fitting the rear half of the drain bend 1 and the drain bend 2.

[0007] Beneficial effect: This solution reduces the weight of the toilet while maintaining the stability of the structure through the reasonable design of the siphon pipe and support block, effectively solving the problem of the heavy weight of the one-piece toilet in the existing technology and improving the convenience of transportation and installation. Specifically, a pair of support blocks are independently arranged in the toilet body to support the toilet bowl, the water trap and the front half of the drain bend 1, and a support block 2 is arranged to support the rear half of the drain bend 1 and the drain bend 2. A large number of solid structures of the toilet body in traditional one-piece toilets are eliminated, and targeted support is provided to key parts, thereby reducing the overall weight of the one-piece toilet; the toilet is limited to a siphonic toilet including a siphon pipe, and the primary buffer section at the water trap position cooperates with the secondary buffer section between the drain bend 1 and the drain bend 2 to form a double buffer, reducing the impact of water flow and excrement on the pipe, and ensuring the stability of the overall structure of the toilet; at the same time, the cross-section of the siphon pipe is limited to a square structure. Compared with the siphon pipe with a circular cross-section, it is beneficial to increase the contact area between the siphon pipe as a whole and the support block 1 and the support pipe 2, enhance the supporting effect of the support block 1 and the support block 2 on the siphon pipe, and thereby enhance the overall structural stability of the toilet.

[0008] Furthermore, as an improvement, the top of the support block 1 away from the drainage bend 1 is in contact with the connection between the toilet bowl cavity and the water trap.

[0009] Beneficial Effect: By fitting the top of Support Block 1 only at the junction of the bowl cavity and the trap, rather than extending across the entire bowl cavity, the material usage of Support Block 1 is significantly reduced. This design further reduces the overall weight of the toilet while ensuring support strength in key areas. It's worth noting that despite the reduced support range of Support Block 1, its close fit at the junction of the bowl cavity and the trap ensures structural stability in key areas, avoiding structural instability caused by reduced material requirements.

[0010] Furthermore, as an improvement, the surface of the support block 1 opposite to the surface on the front half of the drainage bend 1 is in contact with the drainage bend 2.

[0011] Beneficial Effects: By aligning the opposing surface of support block 1 with drain bend 2, support block 2 not only supports the rear half of drain bend 1 and drain bend 2, but also assists support block 1 in supporting the toilet bowl, the trap, and the front half of drain bend 1. This design effectively shares the support burden of support block 1. This combination enables support blocks 1 and 2 to work together, optimizing the overall toilet structure and ensuring the stability and reliability of key areas. It also reduces the load on individual support blocks and extends their service life.

[0012] Furthermore, as an improvement, arc-shaped step 1 and arc-shaped step 2 for buffering are respectively provided in the water trap and the drainage bend.

[0013] Beneficial Effects: The curved steps effectively cushion the impact of water flow and waste, reducing direct impact forces on the pipes. This design significantly reduces vibration and noise caused by impact, extending the pipe's service life while ensuring smooth water flow and the smooth discharge of waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a cross-sectional view of Example 1 of the lightweight one-piece toilet of the present utility model; DETAILED DESCRIPTION

[0015] The following is further described in detail through specific implementation methods:

[0016] The symbols in the drawings of the specification include: toilet body 1, water tank 2, toilet bowl cavity 3, siphon pipe 4, water trap 41, drainage bend 1 42, drainage bend 2 43, curved step 1 44, curved step 2 45, support block 1 5, support block 2 6, and exclusion object 7.

[0017] Example 1

[0018] like Figure 1 As shown, the lightweight one-piece toilet comprises a toilet body 1, a water tank 2, a toilet bowl cavity 3, and a siphon pipe 4. The toilet body 1 is fixedly connected to the water tank 2.

[0019] The cross section of the siphon pipe 4 is square, and the siphon pipe 4 includes a water trap 41 connected to the toilet bowl cavity 3, a drainage bend 1 42 and a drainage bend 2 43 connected to the water trap 41 in sequence. Figure 1 Two dashed lines are shown. The dashed line at the bottom of the toilet bowl 3 represents the connection between the toilet bowl 3 and the trap 41, while the other dashed line represents the connection between drain bend 1 42 and drain bend 2 43. The trap 41 serves as a primary buffer section, while the outlet of drain bend 1 42 is located lower than the inlet of drain bend 2 43, forming a secondary buffer section between the tail of drain bend 1 42 and the head of drain bend 2 43. In this embodiment, curved steps 1 44 and 2 45 are provided within the trap 41 and drain bend, respectively, to provide buffering effects. The dual buffering effect of curved step 1 44 in the primary buffer section and curved step 2 45 in the secondary buffer section reduces the impact of water and excrement on the pipe.

[0020] The toilet body 1 also includes support blocks 1 (5) and 2 (6). Both support blocks 1 (5) and 2 (6) are made of PVC sheet material. PVC has excellent corrosion resistance, high hardness, and high strength, and is lighter than metal, ceramic, and other materials, providing excellent support for the entire toilet. Support block 1 (5) is located entirely at the bottom of the toilet bowl 3 and is adhesively bonded to the water trap 41 and the front half of the drain bend 1 (42). The top of support block 1 (5) away from drain bend 1 (42) is bonded to the junction of the toilet bowl 3 and the water trap 41, and the surface of support block 1 (5) opposite the surface that mates with the front half of drain bend 1 (42) is bonded to drain bend 2 (43). Support block 2 (6) is located entirely at the bottom of drain bend 1 (42) and is adhesively bonded to the back half of drain bend 1 (42) and drain bend 2 (43).

[0021] The specific application process is as follows:

[0022] During use, excreta falls from the toilet bowl 3 into the trap 41. When the user presses the flush button on the water tank 2, water flows from the water tank 2 along the inner wall of the toilet bowl 3 into the trap 41. As the water flows in, the water level at the trap 41 gradually rises. When the water level reaches a certain height, the water carries the excreta (hereinafter referred to as excreta 7) toward drain bends 1 42 and 2 43, forming a siphon effect. Once the siphon is formed, the excreta 7 inside the trap 41 is quickly drawn out because the siphon effect accelerates the flow of water. This process continues until the water level inside the toilet drops to a point where the siphon can no longer be maintained. After the flush is completed, the water tank 2 is refilled, ready for the next flush.

[0023] It is worth noting that support block 1 5 is independently provided within the toilet body 1 to support the toilet bowl 3, the water trap 41, and the front half of the drain bend 1 42. Support block 2 6 is also provided to support the rear half of the drain bend 1 42 and the drain bend 2 43. This eliminates the substantial solid structure of the toilet body 1 found in conventional one-piece toilets, providing targeted support to key areas and thereby reducing the overall weight of the one-piece toilet. The toilet is defined as a siphonic toilet including a siphon pipe 4. The primary buffer section at the water trap 41, combined with the secondary buffer section between the drain bends 1 42 and 2 43, forms a double buffer, reducing the impact of waste 7 on the pipe and ensuring the overall structural stability of the toilet. Furthermore, the cross-section of the siphon pipe 4 is defined as a square structure. Compared to siphon pipes 4 with circular cross-sections, this increases the contact area between the siphon pipe 4 as a whole and the support block 1 5 and support pipe 2, thereby enhancing the support provided by support blocks 1 5 and 2 6 to the siphon pipe 4 and, consequently, the overall structural stability of the toilet.

[0024] The above is only an embodiment of the present invention. The present invention is not limited to the field involved in this implementation case. Common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
