Description

Technical Field

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

[0002] There are two main types of toilets: bottom-discharge and side-discharge. Side-discharge toilets have their connecting pipes inside the wall, while bottom-discharge toilets have their connecting pipes above ground. Currently, most siphon-type toilets are bottom-discharge, while side-discharge toilets are mostly flush-down type. Flush-down toilets use the force of the water flow to expel waste; generally, the back wall of the tank is steeper, and the weight of the water flow helps flush waste from the apex of the tank into the drain pipe. Compared to siphon-type toilets, flush-down toilets have a series of problems, including louder flushing noise, higher water consumption, and a greater tendency to splash. Therefore, siphon-type toilets are more popular with customers than flush-down toilets. However, most siphon-type toilets are bottom-discharge, which cannot meet the needs of wall-mounted drainage systems in some domestic and international installation areas.

[0003] Existing wall-mounted horizontal siphon toilets have straight-up and straight-down sewage pipes, resulting in low negative pressure inside the pipes and a small drop between the sewage inlet and outlet. This leads to a late siphon start time, short duration, and poor sewage discharge capacity. Utility Model Content

[0004] This utility model aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, this utility model proposes a horizontal siphon-type toilet, which is floor-mounted and suitable for both wall drainage and strong siphon sewage discharge.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] According to an embodiment of the present utility model, a horizontal siphon toilet includes a sewage pipe and a basin. The sewage pipe includes an ascending section, a bending section, a descending section and a sewage discharge section connected sequentially along the sewage discharge direction. The sewage discharge section has a sewage discharge port at its end. The axis of the sewage discharge port is horizontal. The sewage discharge section is bent to connect the descending section and the sewage discharge port. The lower end of the rear inner wall of the descending section has a forward-extending protrusion.

[0007] The horizontal siphon toilet according to the embodiment of this utility model has at least the following beneficial effects:

[0008] This invention features a protrusion on the rear wall of the descending section. When the water flows through the bend and enters the descending section, it collides with the protrusion, causing the water to disperse and forming a water curtain that isolates the air in the sewage discharge section. External air cannot enter the sewage pipe from the sewage outlet. At this time, a negative pressure space is generated in the bend section, resulting in a siphon effect. All remaining water and sewage are sucked into the sewage pipe and discharged from the sewage outlet.

[0009] According to some embodiments of the present invention, the horizontal length d of the protrusion extending forward relative to the rear inner wall of the descending section is 12mm-17mm.

[0010] According to some embodiments of the present invention, the protrusion is a convex arc surface, which smoothly transitions to the rear inner wall of the descending section through an inclined surface, and the angle β between the inclined surface and the horizontal plane is 60°-70°.

[0011] According to some embodiments of this utility model, the cross-section of the bending segment has an upper arc segment, a lower arc segment, and a transition arc segment connecting the upper and lower arc segments. The upper arc segment is located in the upper half of the bending segment, and the lower arc segment is located in the lower half of the bending segment. The ratio of the radius R1 of the lower arc segment to the radius R2 of the upper arc segment is greater than 2:1. The ratio of the chord length L1 of the lower arc segment to the chord length L2 of the upper arc segment is (0.7-1):1. The upper and lower ends of the transition arc segment are smoothly connected to the upper and lower arc segments, respectively. The ratio of the length of the longitudinal axis L3 to the transverse axis L4 of the cross-section of the bending segment is 1±0.2.

[0012] According to some embodiments of this utility model, the ratio of the radius R1 of the lower arc segment to the radius R2 of the upper arc segment is (3-6):1.

[0013] According to some embodiments of the present invention, the ratio of the horizontal axis L4 to the chord length L2 is 1:(0.9-1).

[0014] According to some embodiments of the present invention, a supporting rib plate is also included, the upper end of which is connected to the sewage pipe, and the lower end extends downward to the bottom of the toilet body.

[0015] According to some embodiments of the present invention, it further includes a sludge accumulation section located at the lower end of the basin section. The front end of the rising section is a sludge inlet. The sludge accumulation section connects the basin section and the sludge inlet. The front wall of the sludge accumulation section is provided with a spray hole, which is opposite to the position of the sludge inlet. The front end of the bottom wall of the sludge accumulation section is higher than the rear end. The front end and the rear end of the bottom wall are smoothly transitioned by a sloping section. The rear end of the bottom wall of the sludge accumulation section is smoothly connected to the sludge inlet.

[0016] According to some embodiments of this utility model, the direction of the water flow from the jet hole is consistent with the slope of the ramp section.

[0017] According to some embodiments of the present invention, the slope α of the ramp section relative to the horizontal plane is 10°±2°.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figure 1-6 A horizontal siphon toilet includes a drain pipe 100 and a basin 200. The drain pipe 100 includes an ascending section 110, a bending section 120, a descending section 130 and a drain section 140 connected sequentially along the drain direction. The drain section 140 has a drain outlet 141 at its end. The axis of the drain outlet 141 is horizontal. The drain section 140 is bent to connect the descending section 130 and the drain outlet 141. The lower end of the rear inner wall of the descending section 130 has a forward-extending protrusion 131.

[0030] Working principle: When the water flows through the bend section 120 and enters the descending section 130, the water flow collides with the protrusion 131, causing the water flow to disperse and form a water curtain that can isolate the air in the sewage discharge section 140. External air cannot enter the sewage pipe 100 from the sewage outlet 141. At this time, a negative pressure space is generated in the bend section 120, thereby generating a siphon effect. The remaining water flow and sewage are all sucked into the sewage pipe 100 and discharged from the sewage outlet 141.

[0031] In some embodiments of this utility model, the horizontal length d of the protrusion 131 extending forward relative to the rear inner wall of the descending section 130 is 12mm-17mm. The horizontal length d of the protrusion 131 extending forward should not be too large or too small. If it is too large, the collision and dispersion of the water flow when passing through the protrusion 131 will not meet the expected requirements, resulting in a dispersed water flow rather than a curtain-like water flow when entering the sewage discharge section 140. If it is too small, the water flow will not collide as expected when passing through the protrusion 131 and will directly enter the sewage discharge section 140, causing the pipe to fail to produce a siphon effect. Therefore, preferably, the horizontal length d of extending forward is designed to be 12mm-17mm, which allows the water flow to produce the expected effect when passing through the protrusion 131, thereby facilitating the rapid activation of the siphon effect of the sewage discharge pipe 100.

[0032] In some embodiments of this invention, the protrusion 131 is a convex arc surface, which smoothly transitions to the rear inner wall of the descending section 130 via an inclined plane 132. The angle β between the inclined plane 132 and the horizontal plane is 60°-70°. The inclination of the inclined plane 132 should not be too large or too small. If the angle β is too large, the drop between the protrusion 131 and the rear wall of the descending section 130 is insufficient, resulting in insufficient collision force. The water flow cannot be dispersed as expected, making it difficult to form a water curtain that isolates the air, thus affecting the siphon effect. If the angle β is too small, the drop between the protrusion 131 and the rear wall of the descending section 130 is too large, and the direction of the water flow impacting the protrusion 131 will deviate from the expected direction, potentially causing violent water rebound or uneven dispersion. Similarly, it will be impossible to form an ideal water curtain, ultimately making it difficult for the siphon effect to start smoothly. The included angle β is 60°-70°. This angle range allows the water flow to smoothly transition from the inclined surface 132 to the convex arc surface, ensuring that the water flow collides effectively with the protrusion 131, causing the water flow to spread evenly and form a water curtain, thus creating conditions for the generation of the siphon phenomenon.

[0033] In some embodiments of this utility model, such as Figure 3-5 As shown, the cross-section of the bending segment 120 has an upper circular arc segment 121, a lower circular arc segment 122, and a transition circular arc segment 123 connecting the upper circular arc segment 121 and the lower circular arc segment 122. The upper circular arc segment 121 is located in the upper half of the bending segment 120, and the lower circular arc segment 122 is located in the lower half of the bending segment 120. The ratio of the radius R1 of the lower circular arc segment 122 to the radius R2 of the upper circular arc segment 121 is greater than 2:1. The ratio of the chord length L1 of the lower circular arc segment 122 to the chord length L2 of the upper circular arc segment 121 is (0.7-1):1. The upper and lower ends of the transition circular arc segment 123 are smoothly connected to the upper circular arc segment 121 and the lower circular arc segment 122, respectively. The ratio of the length of the longitudinal axis L3 to the transverse axis L4 of the cross-section of the bending segment 120 is 1±0.2. The bend section 120 is located at the highest point of the sewage pipe 100. The horizontal axis is the axis passing through the center of the bend section 120 in the horizontal direction, and the vertical axis is the axis passing through the center of the bend section 120 in the vertical direction. The two ends of the vertical axis are the midpoints of the upper arc section 121 and the lower arc section 122, respectively. The radius of the arc of the cross-section of the rising section 110 and the descending section 130 is smaller than the radius of the lower arc section 122 of the bend section 120.

[0034] Existing siphon pipes have a nearly circular cross-sectional area, meaning the curvature is almost uniform throughout. During operation, the speed and force of the waste and water flow through the bend 120 are crucial factors in the pipe's siphon capacity. Only when the waste and water flow can instantly pass through the bend 120 and smoothly enter the descending section 130 can the siphon effect be truly realized. When waste enters the bend 120, the water flow is affected by gravity during the impact, concentrating more in the lower half of the pipe. Therefore, if the waste is piled high, the force exerted on the waste at higher elevations differs from that at lower elevations; the waste at the bottom experiences greater force and is more easily pushed, while the waste at higher elevations experiences less force, thus hindering its flow. The curved section 120 of this invention features a lower arc section 122 with a smaller curvature (i.e., a larger radius). When actual waste enters the curved section 120, the larger the radius of the lower arc section 122, the smaller the height of the waste accumulation, the more concentrated the water flow force, the less resistance, and the easier it is to be flushed into the descending section 130. Specifically, the main functions of the inlet 111 and the rising section 110 are waste accumulation and a transition section for entering the curved section 120. At the inlet 111, water fills the inlet 111. When the water flows out from the flush end of the toilet and the jet hole 410, the water flow force is consistent throughout the inlet 111. Therefore, the higher the waste accumulation, the easier it is to flush into the rising section 110. From the rising section 110 to the bend section 120, the water flows upwards and, due to gravity, the flow is more concentrated at the bottom. Therefore, based on the water flow characteristics, the lower arc section 122 is designed with a gentler slope and a larger radius. Debris is concentrated at the lower end of the pipe in this section, reducing the height of the debris buildup. This allows the water flow force to better propel the debris out of the bend section 120. Furthermore, the reduced height of the debris buildup in the bend section 120 decreases the height the debris must climb from the rising section 110 into the bend section 120, reducing the gravitational resistance and further facilitating the removal of debris. The bend 120 of the siphon pipe is prone to clogging. The bend 120 of this invention is a modified circular shape, with a gentle slope in the lower half and a dome-shaped upper half. This not only preserves the load-bearing capacity of the circular pipe during the firing process, but also increases the cross-sectional area of ​​the bend 120 compared to other parts of the sewage pipe 100 (such as the rising section 110 and the descending section 130), further reducing the probability of clogging in the bend 120. Furthermore, the narrow-at-the-top, wide-at-the-bottom cross-sectional structure adapts to the gravity effect of water flow as it rises, concentrating the water flow in the lower half, enhancing the impact force in the lower half, and reducing the accumulation of debris.

[0035] In some embodiments of this utility model, the ratio of the radius R1 of the lower arc segment 122 to the radius R2 of the upper arc segment 121 is (3-6):1.

[0036] In some embodiments of this utility model, the ratio of the horizontal axis L4 to the chord length L2 is 1:(0.9-1). The horizontal axis L4 is slightly greater than or equal to the chord length L2. When the ratio of the horizontal axis L4 to the chord length L2 is 1:1, the horizontal axis L4 coincides with the chord length L2, that is, the upper arc segment 121 is a semicircle.

[0037] In some embodiments of this utility model, a supporting rib plate 300 is also included. The upper end of the supporting rib plate 300 is connected to the drain pipe 100, and the lower end extends downward to the bottom of the toilet body. The supporting rib plate 300 connects the drain pipe 100 to the base of the toilet body. The supporting rib plate 300 can effectively support the drain pipe 100, ensuring that the drain pipe 100 will not deform during the drying and firing vitrification stages, thus guaranteeing the function of the pipe.

[0038] In some embodiments of this utility model, a sludge accumulation section 400 is also included. The sludge accumulation section 400 is located at the lower end of the basin section 200, and the front end of the rising section 110 is a sludge inlet 111. The sludge accumulation section 400 connects the basin section 200 and the sludge inlet 111. The front wall of the sludge accumulation section 400 is provided with a spray hole 410, which is positioned opposite to the sludge inlet 111. The front end of the bottom wall of the sludge accumulation section 400 is higher than the rear end, and the front and rear ends of the bottom wall are smoothly transitioned by a ramp section 420. The rear end of the bottom wall of the sludge accumulation section 400 is smoothly connected to the sludge inlet 111. The center of the drain outlet 141 is lower than the center of the sludge inlet 111, and the spray hole 410 is close to the bottom wall of the sludge accumulation section 400. When the machine is started, the basin 200 forms a vortex water flow into the sludge accumulation section 400. At the same time, the water jet from the jet hole 410 pushes the water and dirt in the sludge accumulation section 400 into the sludge inlet 111. Due to the swirling force of the water flow in the basin 200 and the force of the jet water, as well as the design of the sloping section 420 at the bottom of the sludge accumulation section 400, the water flow can easily pass through the rising section 110 to reach the bending section 120.

[0039] In some embodiments of this utility model, the direction of the water jet from the jet hole 410 is consistent with the slope of the ramp section 420. The jet hole 410 is drilled at an angle so that it can eject a water jet with the same slope as the ramp section 420. In this way, the water jet will not hit the bottom wall of the rising section 110 or the dirt accumulation section 400, but will directly impact the dirt.

[0040] In some embodiments of this utility model, the slope α of the ramp section 420 relative to the horizontal plane is 10°±2°. A slope of approximately 10° in the ramp section 420 facilitates the movement of waste from the accumulation section 400 into the drain pipe. This slope should not be too large or too small. If it is too large, the waste will slide directly into the accumulation section 400 and concentrate at the inlet 111, causing the angle between the bottom wall of the accumulation section 400 and the slope 132 of the rising section 110 to decrease. During flushing, the direction of the water jet is consistent with the slope of the ramp section 420, but the waste is concentrated in the rising section 110, preventing the waste and water from being smoothly pushed towards the bend section 120. If it is too small, the bottom wall of the accumulation section 400 will not provide a sliding effect for the waste. Therefore, preferably, the slope α is set to approximately 10°, allowing the waste and water to reach the top of the drain pipe 100 more easily.
