Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The present invention relates to a toilet, comprising a main body 100.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the main body 100 has a water guiding surface 200, a washing surface 300, and a waste collection port 400. The water guiding surface 200, the washing surface 300, and the waste collection port 400 are connected sequentially from top to bottom to form a cone-shaped toilet chamber that gradually narrows from top to bottom. The upper part of the main body 100 has a water outlet 500 facing the water guiding surface 200. The water guiding surface 200 is arranged around the upper end of the washing surface 300, and the water guiding surface 200 is inclined from the side away from the washing surface 300 to the side closer to the washing surface 300, with an inclination less than that of the washing surface 300. The junction between the water guiding surface 200 and the washing surface 300 is a curved transition. The front side of the washing surface 300 has a downwardly recessed surface 310, which is curved and tends to be V-shaped. The concave surface 310 is located off-center from the front of the washing surface 300, i.e., from a top view, as shown in the figure, the first dashed line 810 is located at the center of the washing surface 300 in the left-right direction, and the first dashed line 810 is also the centerline of the main body 100 in the left-right direction. The concave surface 310 can be located to the left or right of the first dashed line 810. The concave surface 310 extends from the water guiding surface 200 towards the dirt accumulation port 400. The upper end of the concave surface 310 can be close to or connected to the water guiding surface 200, and the lower end of the concave surface 310 is connected to the upper end of the dirt accumulation port 400. The water outlet 500 and the concave surface 310 are located on the same side of the main body 100 in the left-right direction, and the water outlet 500 faces forward. In this embodiment, the concave surface 310 is located to the left of the first dashed line 810, and correspondingly, the water outlet 500 is located to the left of the water guiding surface 200. Alternatively, the concave surface 310 can be located to the right of the first dashed line 810, and correspondingly, the outlet 500 is located to the right of the guide surface 200. Preferably, the centerline of the concave surface 310 in the left-right direction (the second dashed line 820 in the figure) intersects the centerline of the main body 100 in the left-right direction (the first dashed line 810), with the intersection point located within the top-view projection range of the sludge collection port 400, and the angle formed by the centerline of the concave surface 310 and the centerline of the main body 100 is within the range of 15° to 20°. The concave surface 310 is positioned in this location. The external water supply system is connected to the outlet 500. Water is sprayed from the outlet 500 to the guide surface 200. The water flows along the circumference of the guide surface 200. When flowing along the guide surface 200, some water will first flow down to form auxiliary flushing water, which flows into the washing surface 300 and the concave surface 310 for rinsing. Most of the water (main flushing water) rotates once along the circumference of the guide surface 200 and then flows into the washing surface 300 from the left rear side. Then, according to centrifugal force, it continues to flow along the washing surface 300 to its front side.When water flows along the cleaning surface 300 to the concave surface 310, the concave surface 310 creates resistance in the circumferential direction of the cleaning surface 300, preventing most of the water from passing through the concave surface 310. This causes the water to collect in the concave surface 310, forming a swirling water flow that rushes downwards towards the sludge collection port 400. Since the auxiliary flushing water enters the sludge collection port 400 slightly earlier than the main flushing water, it flushes the dirt attached to the cleaning surface 300 into the sludge collection port 400 in advance. The horizontal swirling flow generated by the auxiliary flushing water also disperses and propels the dirt in the sludge collection port 400 in advance. The main flushing water and the auxiliary flushing water mix, creating a strong impact on the sludge collection port 400, thereby discharging the dirt in the sludge collection port 400 into the subsequent drain pipe. The flushing process can meet the sewage treatment needs without the need for a separate auxiliary spray nozzle at the sludge collection port 400, resulting in high flushing and sewage discharge capacity and low noise.

[0025] In one embodiment, such as Figure 1 As shown, the water guide surface 200 is inclined from front to back, with the front higher than the back. The water outlet 500 sprays water forward, and the water flows along the circumference of the water guide surface 200, first from the left rear side to the front side. During this process, the water rises, converting some kinetic energy into gravitational potential energy, and the water velocity decreases, effectively preventing splashing due to excessive water speed. Then, as the water flows past the left front end of the water guide surface 200 and changes direction to the right, the water flows from front to back on the right side of the guide surface. At this time, the water flows downhill, and gravitational potential energy is converted back into kinetic potential energy, increasing the water velocity. This ensures that the water flows into the washing surface 300 with force after completing one revolution around the water guide surface 200. The water guide surface 200 includes a guide section 210, a baffle 220, and an edge 230. The guide section 210 is connected to the upper end of the washing surface 300. The guide section 210 extends downward at an angle from the side away from the upper end of the washing surface 300 towards the side closer to the washing surface 300, and the angle of the guide section 210 is less than the angle of the washing surface 300. An upwardly extending baffle 220 is provided on the outer side of the guide section 210 (i.e., the side of the guide section 210 away from the washing surface 300), and an edge 230 extends from the upper side of the baffle 220 towards the center of the water guide surface 200. After water is ejected from the outlet 500, it flows along the guide section 210. Due to centrifugal force, the water flow impacts the baffle 220, preventing it from flying out of the main body 100. If the water flow from the outlet 500 is too large, some of the water will impact the baffle 220 and flow upward, then fall back onto the guide section 210 or the washing surface 300 via the edge.

[0026] In one embodiment, such as Figure 3As shown, the main body 100 is also provided with a water outlet channel 600 communicating with the water outlet 500. The water outlet channel 600 has at least two arc-shaped protrusions 610 arranged sequentially along the water flow direction. In this embodiment, in the direction shown in the figure, the water flows from back to front along the water outlet channel 600, and the arc-shaped protrusions 610 are arranged sequentially from back to front in the water outlet channel 600. Two adjacent arc-shaped protrusions 610 are distributed on both sides of the water outlet channel 600 and protrude in opposite directions. In the direction shown in the figure, two adjacent arc-shaped protrusions 610 are distributed left and right in the water outlet channel 600, with the arc-shaped protrusion 610 on the left protruding to the left and the arc-shaped protrusion 610 on the right protruding to the right, so that the interior of the water outlet channel 600 forms a wave-like flow channel. The upstream end of the water outlet channel 600 is connected to an external water supply system. Before the water flows through the outlet channel 600 and exits through the outlet 500, it impacts the various arc-shaped protrusions 610. The arc surface of the arc-shaped protrusions 610 prevents the water from making a collision noise when it impacts them, thus reducing noise. At the same time, it also reduces the water flow velocity, preventing splashing when the water flows out of the outlet 500 due to excessively high water pressure from the external system. Among them, the arc-shaped protrusion 610 closest to the outlet 500 (i.e., the arc-shaped protrusion 610 located at the downstream end) protrudes in a direction away from the center of the water guide surface 200. After the water flow impacts the downstream arc-shaped protrusion 610, the arc-shaped protrusion 610 guides the water flow. When the water flow exits the outlet 500, it can flow as close as possible to the baffle 220 in the water guide surface 200, ensuring that the water flow can flow completely along the circumference of the water guide surface 200. The resulting auxiliary flushing water washes the entire washing surface 300 along the guide section 210.

[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the sludge collection port 400 includes a front surface portion 410 and a rear surface portion 420, which are distributed front to back. Both the front surface portion 410 and the rear surface portion 420 can be configured as sloped surfaces sloping downwards. The highest height of the front surface portion 410 is lower than the highest height of the rear surface portion 420. When water flows from the washing surface 300 or the concave surface 310 into the front surface portion 410, because the front surface portion 410 is lower than the rear surface portion 420, it can prevent the main flush water from splashing upwards from the rear surface portion 420 due to excessive water volume when flowing down from the front surface portion 410.

[0028] In one embodiment, such as Figure 1 and Figure 3As shown, the sludge collection port 400 also includes a side surface portion 430 and a bottom surface portion 440. The two side surface portions 430 are respectively connected between the left and right sides of the front surface portion 410 and the left and right sides of the rear surface portion 420. The bottom surface portion 440 is connected between the bottom side of the front surface portion 410 and the two side surface portions 430. The rear side of the bottom surface portion 440 is not connected to the rear surface portion 420, and the bottom surface portion 440 is inclined from front to back, with the front being higher than the rear. After the water flows into the sludge collection port 400, under the guidance of the bottom surface portion 440, the water flow is more concentrated and gathers towards the rear bottom of the sludge collection port 400, further increasing the water flow force. The slope of the circumferential sidewall of the sewage outlet 400 gradually increases from front to back. That is, the slope of the front surface portion 410, the side surface portion 430, and the rear surface portion 420 of the sewage outlet 400 gradually increases, which helps to prevent sewage from sticking to the circumferential sidewall of the sewage outlet 400 when defecating.

[0029] In one embodiment, such as Figure 1 As shown, the main body 100 also includes a sewage pipe 700. The sewage pipe 700 includes a connecting section 710, an ascending section 720, and a descending section 730 arranged sequentially. Along the sewage discharge direction, the connecting section 710 is located upstream, and the descending section 730 is located downstream. The connecting section 710 is connected to the downstream side of the sewage inlet 400. The ascending section 720 extends obliquely upward from the downstream end of the connecting section, and the descending section 730 extends downward from the downstream end of the ascending section 720 to below the connecting section 710. The transition position between the ascending section 720 and the descending section 730 is arc-shaped, and the entire sewage pipe 700 can be configured in a C-shape. The lowest point at the transition position between the ascending section 720 and the descending section 730 is higher than the lowest point of the sewage inlet 400, and water forms a water seal in the sewage inlet 400, the connecting section 710, and the ascending section 720. The sewage pipe 700 is a non-siphonic pipe and also an unconventional flush pipe. The inner wall of the sewage pipe 700 has smooth lines and no structure designed to obstruct water flow, so that the water and sewage entering the sewage pipe 700 will not produce any water flow noise. In addition, the sewage pipe 700 is not a jet siphon pipe, so there is no loud noise from jetting water or the sound generated by siphoning, which has a good noise reduction function.
