Description

Technical Field

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

[0002] In the field of sanitary ware technology, the flush toilet, as a common product type, primarily works by using the gravitational impact of water flow to flush away waste. Specifically, when water is released from the tank, the water, under its own gravity, impacts the waste inside the toilet bowl with a certain speed and pressure, forcing it into the inlet and completing the flushing process. Compared to siphon toilets, this design is simpler and more straightforward in structure and working principle, making it easier to understand and maintain.

[0003] During the use of flush toilets, floating debris on the water surface is a common cleaning challenge. As the water flow from the flush nozzles washes along the inner wall of the toilet bowl, the impact of the water flow becomes dispersed and weakens as the water volume decreases. This dispersed water flow is insufficient to effectively flush all floating debris into the drain pipe and out of the toilet. Therefore, this floating debris tends to remain on the inner wall of the toilet bowl or on the water surface, preventing the toilet from being cleaned completely in one flush. To thoroughly remove this residue, users usually need to initiate a second flush. This need for multiple flushes not only increases water consumption but also reduces the convenience of using the toilet, which is detrimental to water conservation and environmental protection. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a flush toilet that, through structural improvements, greatly enhances the flushing effect on floating waste.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a flush toilet, including a toilet seat, the toilet seat including a bowl and a drain pipe, a water seal area is formed at the bottom of the bowl, one end of the drain pipe is connected to the water seal area, and a brush hole for rinsing its inner surface is provided at the top of the bowl; the bowl is also provided with a downward flushing hole, the water outlet direction of the downward flushing hole is downward along the inner wall of the bowl, so as to flush water into the water seal area; the downward flushing hole and the brush hole are configured such that the downward flushing hole exits water before the brush hole.

[0006] In a preferred embodiment, the toilet seat further includes a flushing channel, wherein both the flushing hole and the brushing hole are connected to the flushing channel. The configuration includes: the opening of the flushing hole is positioned lower than the opening of the brushing hole, so that gravity causes water entering the flushing channel to preferentially flow towards the flushing hole. In a preferred embodiment, the flushing channel includes an upper water chamber and a lower water chamber that are interconnected. The upper water chamber has a water inlet, and the lower water chamber is located below the upper water chamber. The brushing hole is connected to the upper water chamber, and the flushing hole is connected to the lower water chamber.

[0007] In a preferred embodiment, the cross-sectional area of ​​the lower chamber is smaller than that of the upper chamber, and the flow area of ​​the flushing hole is smaller than that of the lower chamber; the flushing channel is located at the rear of the toilet bowl, the brushing hole is located at the front of the upper chamber, and the flushing hole is located at the bottom of the lower chamber.

[0008] In a preferred embodiment, the scrubbing hole is located at the first end of the rear sidewall of the toilet bowl, and the water outlet direction of the scrubbing hole is forward. The flushing hole is located at the rear sidewall of the toilet bowl and is offset from the second end of the rear sidewall of the toilet bowl. The first end is one of the left and right ends of the rear sidewall of the toilet bowl, and the second end is the other of the left and right ends of the rear sidewall of the toilet bowl.

[0009] In a preferred embodiment, the rear sidewall of the toilet bowl is provided with a transition step, the step surface of which faces the water seal area, and the opening of the flushing hole is located on the step surface of the transition step, so that the flushing hole is hidden.

[0010] In a preferred embodiment, there are multiple flushing holes, which are spaced apart along the left-right direction of the toilet bowl.

[0011] In a preferred embodiment, there are two flushing holes, one of which is centrally located in the left-right direction of the rear sidewall of the toilet bowl, and the other flushing hole is located on the side of the one flushing hole close to the brushing hole.

[0012] In a preferred embodiment, the diameter of the diving hole is 10-16 mm.

[0013] In a preferred embodiment, a flow guide is provided at the top of the inner wall of the toilet bowl to guide the water flow output from the brush hole to flow circumferentially along the inner wall of the toilet bowl.

[0014] In a preferred embodiment, the toilet seat is a wall-mounted structure; the flushing hole is concealed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Because the toilet bowl also has a flushing hole, the water outlet of which flows downwards along the inner wall of the toilet bowl. The flushing hole and the brushing hole are configured such that the flushing hole outlets water first, allowing the water flow from the flushing hole to exert a downward impact force on floating debris on the water surface during the initial flushing stage. This forces the debris to sink quickly and be guided into the drain pipe. Then, the water flow from the brushing hole flushes the inner wall of the toilet bowl and efficiently removes the debris. Therefore, this invention significantly improves sewage discharge performance while achieving significant water conservation and enhancing the user experience.

[0017] 2. This utility model also includes a flushing channel, and both the flushing hole and the brushing hole are connected to the flushing channel. The structural configuration includes: the orifice of the flushing hole is lower than the orifice of the brushing hole, so that the water flowing into the flushing channel will preferentially flow to the flushing hole by using gravity. Therefore, this utility model can achieve the function of preferential water discharge of the flushing water with a relatively simple structural configuration, so that the overall structure is relatively simple and compact, and it is conducive to reducing production costs.

[0018] 3. The cross-sectional area of ​​the drain chamber is smaller than that of the upper chamber, which helps to ensure that the total flushing volume of the flushing holes is less than that of the brushing holes, thus ensuring effective flushing of the toilet bowl's inner wall by the brushing holes. The flow area of ​​the flushing holes is smaller than that of the drain chamber, which helps to increase the water flow velocity, creating a high-speed flushing flow from the flushing holes.

[0019] 4. The scrubbing hole is located at the first end of the rear side wall of the toilet bowl, and the flushing hole is located at the second end of the rear side wall of the toilet bowl, offset from the second end of the rear side wall of the toilet bowl. The first end is one of the left and right ends of the rear side wall of the toilet bowl, and the second end is the other of the left and right ends of the rear side wall of the toilet bowl. This arrangement of the scrubbing hole and the flushing hole on the same side is beneficial to better push floating waste into the water seal area and the sewage pipe, thereby improving the sewage discharge effect.

[0020] 5. Multiple flushing holes are provided, preferably two, and the diameter of the flushing holes is reasonably controlled to ensure that the flushing volume of the flushing holes meets the requirements while ensuring lateral flushing.

Therefore, they should not be construed as limiting the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, in the description of this utility model, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0031] Please see Figures 1-6As shown, this utility model discloses a flush toilet, including a toilet seat 10, which is a wall-mounted structure, but not limited thereto. The toilet seat 10 includes a bowl 1 and a drain pipe 2. A water seal area is formed at the bottom of the bowl 1, and one end of the drain pipe 2 is connected to the water seal area. A brush hole 11 for rinsing its inner surface is provided at the top of the bowl 1. The bowl 1 also has a downward flushing hole 12, the water outlet direction of which is downward along the inner wall of the bowl to flush the water seal area. The downward water outlet direction includes vertical downward and inclined downward cases; this embodiment uses inclined downward as an example. The flushing hole 12 and the brushing hole 11 are configured such that the flushing hole 12 outputs water before the brushing hole 11. In the initial flushing stage, the flushing water flow formed by the flushing hole 12 can first apply a downward impact force to the floating dirt on the water surface, forcing it to sink quickly and be guided to the drain pipe 2. Then, the water flow output from the brushing hole 11 is used to flush the inner wall of the toilet bowl and promote the efficient discharge of waste.

[0032] The toilet seat 10 also includes a flushing channel 3, through which both the flushing hole 12 and the scrubbing hole 11 are connected, providing flushing water. In this embodiment, the flushing hole 12 and the scrubbing hole 11 are configured such that the opening of the flushing hole 12 is lower than the opening of the scrubbing hole 11, so that gravity causes the water entering the flushing channel 3 to flow preferentially towards the flushing hole 12, thereby achieving the function of water flowing out first from the flushing hole 12. In other embodiments, the flushing hole and the scrubbing hole are configured such that the flow channel between the flushing hole and the scrubbing hole is designed so that the water flows preferentially towards the flushing hole. Specifically, this can be configured as a first branch flow channel supplying water to the flushing hole and a second branch flow channel supplying water to the scrubbing hole, wherein the length of the first branch flow channel is shorter than the length of the second branch flow channel, and / or the cross-sectional area of ​​the first branch flow channel is larger than the cross-sectional area of ​​the second branch flow channel.

[0033] The flushing channel 3 is located behind the toilet bowl 1. The flushing channel 3 includes an interconnected upper water chamber 31 and a lower water chamber 32, with the lower water chamber 32 located below the upper water chamber 31. A brushing hole 11 connects to the upper water chamber 31, and a flushing hole 12 connects to the lower water chamber 32. The brushing hole 11 is located at the front of the upper water chamber 31, and the flushing hole 12 is located at the bottom of the lower water chamber 32. The upper water chamber 31 has a water inlet 311 located on its rear side wall. When water enters through the water inlet 311, the water flow first fills the lower water chamber 32 and then the upper water chamber 31, allowing the flushing hole 12 to exit water before the brushing hole 11.

[0034] As a preferred embodiment, the cross-sectional area of ​​the drain chamber 32 is smaller than that of the upper chamber 31. This is beneficial because the total flushing volume of the flushing hole 12 is less than that of the brushing hole 11, ensuring that the brushing hole 11, as the main flushing hole, can effectively flush the inner wall of the toilet bowl 1. The flow area of ​​the flushing hole 12 is smaller than that of the drain chamber 32, which reduces the water outlet space when the water flows through the flushing hole 12, thereby increasing the flushing speed and creating a high-speed flushing flow from the flushing hole 12.

[0035] In this embodiment, the scrubbing hole 11 is located at the first end of the rear sidewall of the toilet bowl 1, and the water outlet direction of the scrubbing hole 11 is forward. The flushing hole 12 is located on the rear sidewall of the toilet bowl 1, offset from the second end of the rear sidewall of the toilet bowl 1. The first end is one of the left and right ends of the rear sidewall of the toilet bowl, and the second end is the other of the left and right ends of the rear sidewall of the toilet bowl. Therefore, the scrubbing hole 11 and the flushing hole 12 are generally arranged on the same side of the toilet bowl 1. Specifically, when the scrubbing hole 11 is located at the top left end of the rear sidewall of the toilet bowl, the flushing hole 12 is offset from the right end of the rear sidewall of the toilet bowl, and when the scrubbing hole 11 is located at the top right end of the rear sidewall of the toilet bowl, the flushing hole 12 is offset from the left end of the rear sidewall of the toilet bowl.

[0036] As a preferred embodiment, the rear wall of the toilet bowl 1 is provided with a transition step 14, the step surface of which faces the water seal area of ​​the toilet bowl 1. The opening of the flushing hole 12 is located on the step surface of the transition step 14, making the flushing hole 12 largely hidden. This hidden design significantly improves the overall aesthetics of the toilet seat 10 without affecting the flushing effect. Multiple flushing holes 12 are provided, spaced apart along the left-right direction of the toilet bowl 1. As a preferred embodiment, two flushing holes 12 are provided, one of which is centrally located in the left-right direction of the rear wall of the toilet bowl 1, and the other is located on the side of the first flushing hole 12 near the brush hole 11. The diameter of each flushing hole 12 is set to 10-16mm, with a preferred value of 12mm. Therefore, this utility model, by reasonably controlling the diameter and number of flushing holes 12, ensures both lateral flushing and sufficient flushing volume.

[0037] In this embodiment, a guide platform 13 is provided at the top of the inner wall of the toilet bowl 1 to guide the water flow output from the brush hole 11 along the circumference of the inner wall of the toilet bowl 1. Specifically, when water flows out of the brush hole 11, the water flow is divided into two parts: one part flows along the guide platform 13, and the other part flows directly downwards, such as... Figure 6As shown in the diagram, the arrows indicate the direction of water flow. The water flowing along the guide platform 13 can be evenly distributed along the circumferential direction of the inner wall of the toilet bowl 1, achieving a thorough flushing of the inner wall. This design ensures that the water flow can cover all areas of the inner wall of the toilet bowl 1, reducing the residue of waste. The water flowing directly downwards will flush the inner wall surface below the guide platform 13, especially the area near the bottom, effectively removing waste from the bottom.

[0038] The working principle of this flush toilet is as follows:

[0039] When flushing, the water first flows out through the flushing hole 12, mainly flushing downwards to one side of the bottom of the toilet bowl 1 in the left and right direction. This causes the water flow speed on the left and right sides of the bottom of the toilet bowl 1 to be different, which causes the floating waste on one side to sink and move downwards, while the floating waste on the other side tends to float slightly upwards. Then, when flushing through the brushing hole 11, the water flow follows the circumferential direction of the toilet bowl 1. When it flows to the other side of the left and right direction of the toilet bowl 1, more water will flow directly downwards to the bottom of the toilet bowl 1, which can directly push the floating waste with the upward tendency into the water seal area and the sewage pipe 2. If the flushing hole 12 is centered or symmetrically arranged on the rear side wall of the toilet bowl 1, the water flow speed on the left and right sides of the bottom of the toilet bowl 1 will be more consistent. This will cause the floating waste to move downward first. When the water output from the brushing hole 11 participates in the flushing, it will move downward faster on one side, breaking the trend of balanced water flow speed on both sides. This may cause some floating waste to rise back and reduce the sewage discharge effect. However, the overall sewage discharge effect is still better than the sewage discharge effect of simply flushing with the brushing hole 11.

[0040] This utility model discloses a flush toilet that employs a layered flushing technology: In the initial flushing stage, a high-speed downward water flow is generated through the downward-facing flushing holes 12, applying downward impact force to floating debris on the water surface, forcing it to sink quickly and be guided to the drain pipe 2. Subsequently, a three-dimensional flushing mode with annular water distribution is achieved through the brushing holes 11, causing the water flow to form a spiral flush along the inner wall of the toilet bowl 1, ensuring complete coverage. The continuous pressure of the clean water on the surface of the toilet bowl 1 further promotes the efficient discharge of waste. This phased, multi-angle flushing method not only significantly improves the treatment effect on floating debris but also greatly reduces the amount of water used per flush, achieving significant water conservation while maintaining efficient waste disposal.

[0041] The flush toilet of this utility model is identical to or can be implemented using existing technology for the parts not covered (such as the water tank).

[0042] The above embodiments are only used to further illustrate a flush toilet of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
