Description

The present disclosure relates to the technical field of toilet, particularly to a vortex flushing toilet. BACKGROUND At present, the application of toilets is very common, but the existing toilets on the market suffer from incomplete flushing such as contamination and dirt accumulation. It is often necessary to manually clean the surface of the bowl body or perform secondary flushing, which not only generates wastewater but also easily causes bacterial growth. The flush type without rim holes generally uses a opposite-flushing toilet, with the spray hole of the flush toilet set at the front position, extending the distance of the secondary water channel and reducing water pressure, resulting in insufficient water flushing force. For another instance, the disclosure patent with publication number CN215053629U shows that this type of flush toilet product is prone to overflow from the ring surface due to the large flow of flushing water, which can cause sewage to come into contact with the human body and harm human health. SUMMARY In order to solve the above technical problems, the present disclosure provides a vortex flushing toilet, which effectively flushes the area between the rim channel and the toilet body to prevent contamination. In order to achieve the above objective, the present disclosure adopts die following solution: A vortex flushing toilet, including a toilet body, and an interior of toilet body is a bowl body, wherein the toilet body is provided with a rim channel, the front end of the rim channel is provided with a water outlet hole, the lower part of the rim channel below the water outlet hole is provided with a conical annular flow-guiding groove; the bowl body is below the rim channel, and the bowl body is a funnel-shaped structure with a bowl bottom connected to the bottom of the bowl body; the connection position between the bowl body and the bowl bottom is of equal height on both sides, or in a stepped structure; and / or the rear wall of the bowl body is provided with an inclined spray hole, and the spray hole is aligned with the bottom position of the bowl bottom. Further, the connection position between the bowl body and the bowl bottom is in the stepped structure with height on left and low on right or height on right and low on left, and the curvature of the front wall cross-section at the end of the connection position between the bowl body and the bowl bottom away from a water tank is less than n / 6. The change in the shape of the outlet of the bowl body effectively prevents water entering into the bowl bottom from splashing out due to the reverse rotation. Further, the angle between a line connecting the circle centre of the water outlet hole and the circle centre of the cross-section of the rim channel at the plane where the circle centre of the water outlet hole is located and an axis of the toilet body is less than 60°, and a cover plate is installed on the toilet body. The user cannot see the water outlet hole when standing in front of the toilet, which means that the water outlet hole is hidden, improving the aesthetics of the toilet product. Further, the upper top wall of the bowl bottom is an arc-shaped surface with a curvature of n / 4 - jc / 2. Compared to the traditional approximate linear top of the bowl bottom, this scheme increases the curvature of the top of the bowl bottom and reduces the diameter of the bowl bottom. When the bowl bottom is filled with water, it is affected by pressure and produces a siphon phenomenon inside the bowl bottom. The large curved top surface can also produce a flushing phenomenon, making the bowl bottom have both siphon and flushing functions, significantly improving the sewage discharge effect. Further, the connection position between the bowl body and the bowl bottom is of equal height on both sides, and the toilet body further includes a main water channel and a secondary water channel; a water inlet is provided at a rear part of the toilet body, below the water inlet is a rear part of the main water channel; a front part of the main water channel is respectively connected to the rim channel and the secondary water channel. Further, there is a cavity in the rim channel on one side of the water outlet hole, the cavity is the main water channel, and the rim channel on the other side of the water outlet hole is a blocking structure. This design can increase the water pressure at the water outlet hole and facilitate flushing. Further, the spray hole is an elliptical hole, that is, the spray hole is long on the left and right and short on the top and bottom, and the width of the water outlets on left and right is consistent with the width of the water seal surface, which increases the surface area of the water seal covering the product and facilitates the passage of the medium. Further, an outer side of the water outlet hole is provided with a water blocking rim to prevent excessive water flow from causing partial water overflow The connection position between the water blocking rim and the rim channel is designed with a rounded corner, and the angle range of the rounded comer is between 55° and 70°. Further, the vortex flushing toilet further includes a sewage pipeline, the rear end of the bowl bottom is connected to the sewage pipeline, and the diameter of the sewage pipeline is less than or equal to 65mm. Compared to existing technologies, the advantageous effects of the present disclosure are: (1) The toilet provided by the present disclosure is designed with a water outlet hole at the front of the rim channel. Water flows through the rim channel and rushes out from the water outlet hole, then flows along the flow-guiding groove to flush the bowl body, forming a vortex flushing, which mixes with the water flow flushed from the spray hole set on the side wall of the bowl body to achieve flushing of the flow-guiding groove, the bowl body, and the bowl bottom, solving the problem of contamination formed at the position of the bowl body and the rim channel in the existing toilet. (2) The present disclosure also adopts another way to set the inner wall of the connection position between the bowl body and the bowl bottom in a shape where the left (or right) side is high and the opposite side is low. The high side extends along with the inner wall of the volute-shape bowl body, and the low side is the water inlet position of the bowl body towards the bowl bottom. Through this height difference, the rotating water flow in the bowl body smoothly enters the bowl bottom, discharges the dirt, and avoids the water flow in the bowl body from swinging left and right and overflowing. The combination of a stepped connection structure and inclined spray holes results in a more prominent effect. (3) The conical annular flow-guiding groove in the present disclosure is smoothly connected to the volute-shape bowl body, allowing water flow to smoothly enter the bowl bottom along the spiral inner wall of the bowl body, reducing water flow collision.

DETAILED DESCRIPTION OF THE EMBODIMENTS In order to fully understand the objective, features, and efficacy of the present disclosure, the following specific embodiments are used to provide a detailed illustration of the present disclosure, but the present disclosure is not limited to them. The present disclosure provides a vortex flushing toilet, including a toilet body 1. The toilet body 1 includes an upper panel, a rim channel 2, a bowl body 3, a bowl bottom 5, a sewage pipeline 10 and so on, the rim channel 2 is located in the upper part of the toilet body 1 and is connected to the upper panel of the toilet body 1, the lower edge of the rim channel 2 is connected to a conical annular shaped flow-guiding groove 9, and the lower edge of the flow-guiding groove 9 is connected to the bowl body 3 in a smooth manner to form a smooth conical curved surface. The rim channel 2 is a ring-shaped structure, and a water outlet hole 4 is provided on the side wall of the rim channel 2 close to the inner cavity of the toilet body 1, and the water flowing out of the water outlet hole 4 rinses the bowl body 3 along the flow-guiding groove 9, forming a rotary flushing. The water outlet hole 4 is provided with a water blocking rim 41 on the outside, the water blocking rim 41 can block the flushing hole water flow is too large to cause part of the water overflow, so as to solve the problem of product splashing, which is conducive to the product flushing angle control. Preferably, the connection between the water blocking rim 41 and the rim channel 2 is designed with a rounded corner, and the angle range of the rounded corner is between 55° and 70°. The bowl body 3 is in a funnel-shaped structure, which is conducive to the downward flushing of water flow and increases the water flow velocity. The bottom of the bowl body 3 is equipped with a bowl bottom 5, and the bowl bottom 5 is connected to the sewage pipeline 10. Preferably, the diameter of the sewage pipeline 10 is less than or equal to 65mm. Embodiment 1: As shown in FIG. 1 - FIG. 4 (in order to better show the curvature change of the product, the actual object scanning line is shown in the form of a dotted line inside), the angle 0 between the line connecting the circle centre of the water outlet hole 4 and the circle centre of the rim channel 2 where the circle centre of the water outlet hole 4 is located and the axis of symmetry of the toilet where the circle centre of the water outlet hole 4 is located is less than 60°. After installing the circle-shaped cover of the toilet, as the inner diameter of the cover plate is less than the inner diameter of the upper panel of the toilet body, the water outlet hole 4 is hidden by the cover plate, and the user cannot see the water outlet hole 4 when standing in front of the bidet, which improves the aesthetics of the product. The bowl body 3 is a funnel-shaped structure with a volute-shape inner wall. The initial point of the volute-shape spiral seamlessly and smoothly connects with the flow-guiding groove 9, and the end point of the spiral is the connection position between the bowl body 3 and the bowl bottom 5. The connection position between the bowl body 3 and the bowl bottom 5 is in a stepped structure, that is, high on the left and low on the right or high on the right and low on the left. The connection position is the outlet position of the bowl body 3. The inner walls of the bowl body on both sides of the outlet have different heights. When the toilet is observed in the normal use orientation, the left or right height of the bowl body outlet is higher than the height of the opposite side, forming a rotating drop of different heights to ensure that the water flow carrying dirt smoothly enters the bowl bottom 5, avoiding the phenomenon of only rotating without sinking and the water flow inside the bowl body 3 swaying left and right. In FIG. 3, the height of the left side of outlet 31 is higher than the height of the right side of outlet 32. In some preferred embodiments, the front wall 6 of the outlet of the bowl body is a curved surface, and the curvature of the cross-sectional arc of this curved surface is less than n / 6. Unlike the large curvature circular surface of the original vortex flushing toilet, this curved surface is close to a vertical plane, effectively avoiding water flowing into the bowl bottom 5 from splashing out due to reverse rotation. In this embodiment, the spray hole is omitted, which can effectively reduce the occurrence of splashing and overflow. The top of bowl bottom 7 in FIG. 3 presents arc surface structure with a larger curvature, specific arc preferably in n / 4 - k / 2 . The traditional top of bowl bottom is the approximate planar structure, the arc is significantly smaller than the top of the bowl bottom 7 of this embodiment 7. The diameter of the bowl bottom 5 compared to the traditional toilet discharge outlet is smaller, so when the bowl bottom is full of water, by the pressure within the bowl bottom to produce a siphon phenomenon, and the top surface with large curvature can also produce the phenomenon of flushing down, so that the bowl bottom 5 has both siphon and flushing down function, significantly improving the sewage discharge effect. When in use, the water flow in the water tank flows along the rim channel 2 to the water outlet hole 4, and then rushes out from the outlet hole 4 at an inclined angle. After passing through the flow-guiding groove 9, the water flow rotates and flushes the bowl body 3, and reaches the bottom outlet of the bowl body. Since the inner wall of the bowl body outlet position is high at one side and low at the other side, a spiral channel inclined towards the bowl bottom 5 is formed, and the water flow smoothly fills into the bowl bottom 5, solving the problem of water flow not rotating downward. Embodiment 2: As shown in FIG. 5 - FIG. 6, when the connection position between the bowl body 3 and the bowl bottom 5 is equal in height, the main water channel 11 and the secondary water channel 13 are set inside the toilet body 1. There is a cavity in the rim channel 2 on one side of the water outlet hole 4, which is the main water channel 11. The rim channel 2 on the other side of the water outlet hole 4 is a blocking structure without cavities, which can increase the water pressure at the water outlet hole 4 and facilitate flushing. A water inlet hole 8 is provided at the upper portion in the rear part of the toilet body 1, and the water inlet hole 8 is located above the rear part of the main water channel 11. A secondary water channel 13 is formed between the toilet body 1 and the upper part of the bowl body 3, and the front part of the main water channel 11 is respectively connected to the rim channel 2 and the secondary water channel 13. On the side wall of the bowl body where the secondary water channel 13 is located, there is an inclined spray hole 12, which change the position of the original spray hole. The inclination angle of the spray hole 12 meets the requirement that the water sprayed from the spray hole 12 is directed towards the bottom position of the bowl bottom 5 for flushing. Preferably, the spray hole 12 is a flat elliptical hole, which is long on the left and right, short on the top and bottom. The width of the left and right water outlets is consistent with the width of the water seal surface, which increases the surface area of water seal covering tire product and facilitates the passage of the medium. When in use, the water flow enters the main water channel 11 through the water inlet hole 8, and then splits into two water flows. One water flow passes through the rim channel 2 and is flushed out through the water outlet hole 4 at the front end of the rim channel 2, then rotates and flushes the bowl body through the flow-guiding groove 9; another water flow through the secondary water channel 13 and enters the bowl bottom 5 through the spray hole 12. The two water flows mix and flush, achieving the flushing of the flow-guiding groove 9, the bowl body 3, and the bowl bottom 5, solving the problem of diets formed at the position of the bowl body 3 and the rim channel 2 of the existing toilet. Embodiment 3: Combining Embodiment 1 with Embodiment 2, i.e. the bowel body 3 is connected to the bowl bottom 5 in a stepped structure with the left or right side higher than the opposite side, and the rear side wall of the bowel body 3 is provided with an inclined spray hole 12, which is aligned with the bottom position of the bowl bottom 5. The advantages of the present disclosure over other existing flush toilets are: (1) Easy to clean: The available toilets in the market are generally designed with rim holes or opposite-flushing products, which can easily form dirt at the hole position and are difficult to clean. However, the present disclosure is a vortex flushing toilet with a funnel-shaped bowl body that is easy to clean. (2) Good visual effect: There is dirt on the position of the rim holes of the existing toilet seat, which is difficult for people to accept after long-term use. However, the water outlet position of the present disclosure is located at the front of the product which is visually undetectable, and further provided with a water-blocking rim, which is undetectable. (3) The diameter of the product is relatively small compared to ordinary flush toilets: When the water flows through the funnel-shaped bowl body, it accelerates and flows downwards from the bowl bottom. Due to the fast flow rate, the pipeline is easily filled, which can briefly form a siphon effect to accelerate the discharge of dirt. (4) By connecting the spray hole and / or stepped bowl body with the bowl bottom, the problem of unclean flushing and overflow can be solved. Finally, it should be noted that the above listed embodiments are only preferred embodiments of the present disclosure. Of course, those skilled in the art may make modifications and variations to the present disclosure. If these modifications and variations fall within the scope of the claims and equivalent technologies of the present disclosure, they should be considered as the scope of the present disclosure.
