Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of toilets and, in particular, to a toilet with a vortex flush. STATE OF THE ART

[0002] Today, toilet use is widespread, but existing toilets on the market have problems such as contamination and dirt accumulation, as well as incomplete flushing. Often, it is necessary to manually scrub off impurities on the surface of the pot body or perform a post-flush, which wastes water and easily leads to bacterial growth.Flush toilets without ring holes generally use opposite flush toilets, and the spray holes of the opposite flush toilet are installed at the front, which lengthens the distance of the auxiliary water channel and reduces the water pressure, resulting in insufficient water flushing performance; another example is the invention patent announcement number CN215053629U, this type of flush toilet is prone to excessive water flow for opposite flush, which causes water to overflow from the ring surface, causing sewage to come into contact with the human body and endangering human health. CONTENT OF THE PRESENT INVENTION

[0003] In order to solve the above-mentioned technical problems, the present invention provides a vortex flush toilet that can effectively wash the area between the circular channel and the pot body to prevent contamination.

[0004] To achieve this technical purpose, the present invention applies the following solutions: a vortex flush toilet comprising a toilet body, wherein a bowl body is arranged in the toilet body; the toilet body is provided with an annular circular channel, wherein a front end of the circular channel is provided with a water outlet hole and a lower part of the circular channel below the water outlet hole is provided with a conical guide groove; wherein the bowl body is located below the circular channel, wherein the bowl body has a funnel-shaped structure and a bowl base is connected to the bottom of the bowl body; wherein the connection position between the pot body and the pot bottom is of equal height or stepped on the left and right; and / or wherein a rear side wall of the pot body is provided with an inclined spray hole, and the spray hole is aligned with a lower position of the pot bottom.

[0005] In a further development, it is provided that the connection position between the pot body and the pot bottom is in a step-like structure with the left side high and the right side low, or the right side high and the left side low, wherein an arc of a cross section of a front wall of the connection position between the pot body and the pot bottom facing away from the water tank side is less than π / 6, wherein the changed shape of the outlet of the pot body effectively prevents the water from the pot outlet from flowing into the pot bottom and causing splashes there by turning back.

[0006] In a further development, it is provided that an angle between a line connecting a circle center of the water outlet hole and a center point of the cross section of the circular channel on a plane of the circle center and an axis of the toilet body is less than 60 ° and a cover plate is mounted on the toilet body, and the user cannot see the water outlet hole when standing in front of the toilet, ie the water outlet is concealed, which improves the aesthetics of the toilet product.

[0007] In a further development, an upper cover wall of the pot bottom is provided with an arcuate surface with an arc of π / 4 to π / 2. Compared to the conventional approximately straight top surface of the pot bottom, this solution increases the arc of the top surface of the pot bottom and reduces the pipe diameter of the pot bottom. When the pot bottom is filled with water, a siphoning phenomenon occurs in the pot bottom under the influence of pressure. The large arcuate top surface can also generate a flushing phenomenon, so that the pot bottom has a dual function: siphoning and flushing, thereby significantly improving the wastewater drainage effect.

[0008] In a further development, it is provided that the connection position between the pot body and the pot bottom is the same height on the left and right sides, wherein the toilet body further comprises a main water channel and an auxiliary water channel and a water inlet opening is provided on the rear of the toilet body, wherein a rear part of the main water channel is located below the water inlet opening and a front part of the main water channel is connected to the circular channel and the auxiliary water channel, respectively.

[0009] In a further development, it is provided that a cavity is located in the circular channel on one side of the water outlet hole, and the cavity is the main water channel; wherein the circular channel on the other side of the water outlet hole has a closing structure, and this design can increase the water pressure at the water outlet hole, which is convenient for flushing.

[0010] In a further development, it is provided that the spray hole is an elliptical hole, that is, long on the left and right, short on the top and bottom, and the width for the left and right water outlet matches the width of the water cover, thereby increasing the surface area covered by the water seal of the product, which facilitates the passage of media.

[0011] In a further development, a water retention edge is provided on the outside of the water outlet hole. This edge serves to block the water flow in the flush hole and prevent part of the water from overflowing due to excessive water flow. The connection point between the water retention edge and the circular channel is designed with a rounded section, with an angle of the rounded section ranging between 55° and 70°.

[0012] In a further development, it is provided that the toilet also includes a waste pipe and the rear end of the pot bottom is connected to the waste pipe, and the diameter of the waste pipe is less than or equal to 65 mm.

[0013] Compared with the prior art, the present invention has the following advantageous effects: (1) The toilet provided by the present invention is equipped with a water outlet at the front of the circular channel, and the water flow flows through the circular channel, flows out of the water outlet hole, and washes the pot body along the guide groove, forming a rotating flush, and mixes with the water flow flowing in from the spray hole on the side wall of the pot body, thereby achieving the flushing of the guide groove, the pot body, and the pot bottom, and solving the pollution problem caused by the existing toilet at the position of the pot body and the circular channel; (2) The present invention also uses another method in which the inner wall at the connection position between the pot body and the pot bottom is formed into a shape in which the left (or right) side is high and the opposite side is low, and the high side is extended by the inner wall of the snail-shaped pot body, and the low side is the water inlet position from the pot body to the pot bottom. The rotating water flow in the pot body smoothly penetrates the pot bottom through this height difference, and the dirt is discharged, thereby preventing the water flow in the pot body from swinging left and right and overflowing; the step-shaped connection structure cooperates with the inclined spray hole to achieve a more outstanding effect. (3) In the present invention, the conical ring-shaped guide groove is smoothly connected with the spiral pot body, so that the water flow can smoothly penetrate into the pot bottom along the inner wall of the spiral pot body, thereby reducing the collision of the water flow.

DETAILED DESCRIPTION

[0015] In order to fully understand the purpose, characteristics and effects of the present invention, the present invention will be described in detail by means of the following specific embodiments, but the present invention is not limited thereto.

[0016] The invention provides a swirl-flush toilet comprising a toilet body 1, and the toilet body 1 includes a top plate, a circular channel 2, a bowl body 3, a bowl bottom 5, a drain pipe 10, and the like. The circular channel 2 is located in the upper part of the toilet body 1 and connected to the top plate of the toilet body 1. The lower edge of the circular channel 2 is connected to a conical ring-shaped guide groove 9, the lower edge of the guide groove 9 being extended to the bowl body 3 to form a smooth conical arc surface. The circular channel 2 has an annular structure, and a water outlet hole 4 is provided on the side wall of the circular channel 2 near the interior of the toilet body 1. Water flowing out of the water outlet hole 1 surrounds the bowl body 3 along the guide groove 9, thus forming a rotating flush.A water retention edge 41 is provided on the outside of the water outlet hole 4. The water retention edge 41 can prevent the large water flow in the flushing hole from causing some of the water to overflow, solving the problem of water splashing of the product and facilitating control of the flushing angle of the product. Preferably, the connection point between the water retention edge 41 and the circular channel 2 is provided with a rounded portion, with an angle range of the rounded portion being between 55° and 70°.

[0017] The pot body 3 has a funnel-shaped structure that facilitates downward flushing of water and increases the water flow rate; a pot base 5 is provided at the bottom of the pot body 3, which is connected to the drain pipe 10. Preferably, the diameter of the drain pipe 10 is less than or equal to 65 mm. Example 1:

[0018] As in Fig. 1-4 (in order to better display the arc changes of the product, the actual object scanning lines are displayed in the form of dotted lines inside), an angle between a line connecting a circular center of the water outlet hole 4 and a circular center of the circular channel 2 on the horizontal plane of the circular center, and the axis of symmetry of the toilet on the horizontal plane where the circular center of the water outlet hole 4 is located is less than 60°; after the annular cover plate of the toilet is installed, the water outlet hole 4 is blocked and hidden by the cover plate because the inner diameter of the cover plate is smaller than the inner diameter of the upper plate of the toilet body, and the user cannot see the water outlet hole 4 when standing in front of the toilet, which improves the aesthetics of the toilet product.

[0019] The pot body 3 has a funnel structure with a spiral-shaped inner wall. The starting point of its spiral spiral is seamlessly connected to the guide groove 9, and the end point of its spiral is the connection position between the pot body 3 and the pot bottom 5. The connection position between the pot body 3 and the pot bottom 5 is structured in a stepped manner, i.e., high on the left and low on the right, or high on the right and low on the left. This connection position is the outlet position of the pot body 3, and the inner walls of the pot body on both sides of the outlet have different heights.When viewing the toilet from the normal use position, the height of the left or right side of the outlet of the bowl body is higher than the height of the opposite side, forming a rotational drop with different heights, thereby ensuring that the water flow carrying the dirt smoothly enters the bowl bottom 5 and avoiding the phenomenon that the dirt only rotates but does not sink and the water flow oscillates left and right in the bowl body 3. In . Fig. 3, the height 31 on the left side of the outlet is higher than the height 32 on the right side of the outlet. In some preferred embodiments, it is provided that the front wall 6 of the outlet of the bowl body is an arc surface, and the arc of the cross-sectional arc of the arc surface is less than π / 6. Unlike the circular surface with a large arc of the original vortex flush toilet, this arc surface resembles a vertical plane, which effectively prevents the water flowing from the bowl body 3 into the bowl bottom 5 from rotating in reverse and causing splashing. In the present embodiment, the spray hole is omitted, which can effectively reduce the occurrence of splashing and overflow.

[0020] The top side 7 of the pot base shows an arched surface structure with a large arch from the perspective of Fig. 3, and the specific arc is preferably between π / 4 and π / 2, and the top of the traditional pot bottom has a nearly flat structure, and the arc is significantly smaller than the bottom of the top surface 7 of the pot bottom in this solution; the pipe diameter of the pot bottom 5 is much smaller than the outlet opening of the conventional toilet. Therefore, when the pot bottom is filled with water, a siphoning phenomenon occurs in the pot bottom under the influence of pressure, and the large arc-shaped top can also produce a flushing phenomenon, so the pot bottom 5 has a dual function of siphoning and flushing, thereby significantly improving the sewage drainage effect.

[0021] During use, the water flow in the water tank flows along the circular channel 2 to the water outlet hole 4, then flows diagonally out of the water outlet hole 4, rotates and rinses the pot body 3 through the guide groove 9, and reaches the bottom outlet of the pot body. Since one side of the inner wall at the outlet of the pot body is high and the other side is low, a spiral channel is formed inclined toward the bottom of the pot 5, and the water flow is thus evenly filled into the bottom of the pot 5, solving the problem that the water flow does not rotate downward. Example 2:

[0022] As in Fig.As shown in Figures 5-6, the main water channel 11 and the auxiliary water channel 13 are provided in the toilet body 1 when the connection position of the bowl body 3 and the bowl bottom 5 on the left and right sides are the same height, and a cavity is provided in the circular channel 2 on one side of the water outlet hole 4, and the cavity is the main water channel 11; the circular channel 2 on the other side of the water outlet hole 4 is a cavity-free closing structure, and this design can increase the water pressure at the water outlet hole 4, which is convenient for flushing.

[0023] A water inlet hole 8 is provided above the rear part of the toilet body 1, and a water inlet hole 8 is provided above the rear part of the main water channel 11. The auxiliary 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 circular channel 2 and the auxiliary water channel 13. The side wall of the bowl, where the auxiliary water channel 13 is located, is provided with an inclined spray hole 12 that changes the position of the original spray hole, and the inclination angle of the spray hole 12 is such that the water flow ejected from the spray hole 12 is directed toward the lower position of the bowl bottom 5 for flushing.Preferably, the spray hole 12 is a flat elliptical hole, that is, long on the left and right, short on the top and bottom, and the width for the left and right water outlet is consistent with the width of the water cover, thereby increasing the surface area covering the water seal of the product, which facilitates the passage of media.

[0024] In use, the water flow enters the main water channel 11 through the water inlet hole 8 and then divides into two water flows, one of which flows through the circular channel 2 and flows out of the water outlet hole 4 at the front end of the circular channel 2, passes through the guide groove 9 and rotates to flush the bowl body; another water flow flows through the auxiliary water channel 13 and flows out of the spray hole 12 into the bowl bottom 5, and the two water flows are mixed and flushed to flush the guide groove 9, the bowl body 3 and the bowl bottom 5, thereby solving the problem of pollution of the existing toilet at the bowl body 3 and the circular channel 2. Example 3:

[0025] Embodiment 1 is combined with Embodiment 2, that is, the connection position between the pot body 3 and the pot bottom 5 has a stepped structure where the left or right side is higher than the opposite side, and the rear side wall of the pot body 3 is provided with an inclined spray hole 12, and the spray hole 12 is aligned with the lower position of the pot bottom 5.

[0026] Compared to other existing flush toilets, the advantages of this invention are: (1) Easy to clean: existing toilets are generally ring-hole or opposite-flush products, which are easy to generate dirt at the holes and are difficult to clean, but the present invention is a swirl-flush toilet with a funnel-shaped pot body, which makes cleaning easy. (2) Good visual effects: there is dirt in the ring hole of the existing toilet, which is difficult for people to accept after long-term use, and the water outlet position of the present invention is located at the front of the product, is not visually noticeable, has a water retaining edge, and therefore cannot be discovered. (3) The product pipe diameter is smaller than that of traditional flush toilets: when the water flow passes through the funnel-shaped pot body, it accelerates, and when the water flow flows down from the bottom of the pot, the pipe fills slightly due to the fast flow rate, which can temporarily form a siphon effect and accelerate the drainage of dirt. (4) The spray hole and / or the connecting structure between the stepped pot body and the pot bottom solve the problems of incomplete flushing and overflow.

[0027] Finally, it should be noted that the above-mentioned embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art may make modifications and variations to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and equivalent technologies, they are deemed to be within the scope of protection.
