Description

Title of the invention: Vortex flush toilet technical field

[0001] The present invention falls within the technical field of sanitary appliances and specifically relates to a vortex flush toilet. Previous art

[0002] With the continuous improvement of the quality of life, consumers are paying increasing attention to environmental protection. As a result, water-saving toilets are preferred by many consumers. Among them, the vortex flush toilet is increasingly used thanks to its excellent flushing efficiency and remarkable water-saving performance.

[0003] However, vortex flush toilets currently on the market have a disadvantage: a large volume of air and water converges instantly at the water outlet, generating significant noise and potentially disturbing the rest of users.

[0004] Content of the invention

[0005] To overcome the technical problem existing in the aforementioned prior art, the present invention proposes a vortex flush toilet. During flushing, water flows from the tank to the water inlet, through which it enters the curved channel. At this point, the water flow splits into two parts: the majority of the water passes through the flushing orifice to the water outlet, while a small portion of the water and the air at the top of the curved channel are expelled through the air vent. Purging the air from inside the curved channel through the air vent reduces collisions between water and air at the water outlet during flushing, thus achieving a noise reduction effect.

[0006] The present invention proposes a vortex flush toilet comprising: a toilet body, a water inlet provided inside the toilet body, and a curved channel in communication with the water inlet, provided inside the toilet body, a perforated face provided on the side of the curved channel opposite the water inlet, the perforated face being provided with a flushing orifice as well as an air vent located above the flushing orifice.

[0007] Preferably, the toilet body includes a bowl cavity provided with a bowl surface, and on the bowl surface is provided a water outlet located near the perforated face.

[0008] Preferably, on the side of the basin surface away from the curved channel, a flow guidance platform is provided in communication with the water outlet.

[0009] Preferably, the diameter of the rinsing orifice is greater than the diameter of the air vent.

[0010] Preferably, the curved channel gradually descends from the water inlet to the water outlet.

[0011] Preferably, the diameter of the curved channel gradually decreases from the water inlet to the water outlet.

[0012] Preferably, the surface of the bowl is continuously connected to the toilet body.

[0013] Preferably, the flow guidance platform extends along the curvature of the surface of the bowl and is assembled continuously with the surface of the bowl.

[0014] Preferably, the flow guidance platform lowers and narrows progressively from the water outlet to the water inlet.

[0015] Preferably, the water outlet is located on the far side of the water inlet.

[0016] Compared to the prior art, the present invention has the following advantages:

[0017] (1) During flushing, water flows from the tank to the water inlet through which Water enters the curved channel, where the water flow splits into two parts: most of the water passes through the flushing orifice to the outlet, while a small amount of water and air at the top of the curved channel is expelled through the air vent. Purging air from inside the curved channel through the air vent reduces collisions between water and air at the outlet during flushing, thus reducing noise.

[0018] (2) The curved channel is designed to guide the flow of water from the water inlet up to the surface of the bowl via the water outlet. The bowl's bowl-shaped surface helps create a vortex for flushing, and the toilet bowl surface is continuously connected to the toilet body to reduce dirt buildup, thus facilitating cleaning.

[0019] (3) The section of the vertical plane on the side of the curved channel near the water outlet is smaller than that on the side near the water inlet. The progressive reduction of the cross-section of the vertical plane of the curved channel allows the water flow to accelerate as it exits through the water outlet.

[0020] (4) The flow guidance platform extends on the side near the water outlet towards the side furthest from the water outlet, with a width and height that gradually decrease. The flow guide platform serves to guide the flow of water from the outlet, to form a vortex along the surface of the basin. slowing down the fall of the water flow to allow for a longer rinsing time on the surface of the toilet bowl.

[0027] Specific embodiments

[0028] The technical solutions of the embodiments within the scope of the present invention will be clearly and completely described below in conjunction with the figures of the present invention. It is evident that the embodiments described relate only to a portion of the embodiments according to the present invention, but do not include all of the embodiments. Any other embodiment obtained by a person skilled in the art without expending inventive effort on the basis of the embodiments in the present invention will be covered by the scope of protection of the present invention.

[0029] The present invention will be described in detail below, in conjunction with Figures 1 to 4 and specific embodiments.

[0030] As shown in Figures 1 to 4, the present invention provides a vortex flush toilet, comprising a toilet body 1, inside the toilet body 1 a water inlet 2, said water inlet 2 being connected to the water tank. A curved channel 3 is provided in the toilet body 1, the curved channel 3 surrounding one side of the toilet body 1 in a counterclockwise direction. At the end of the curved channel 3 furthest from the water inlet 2 is a perforated face 4, the face perforated 4 being provided with a rinsing orifice 41 and an air vent 42. The diameter of the rinsing orifice 41 is greater than that of the air vent 42, the air vent 42 being located above the rinsing orifice 41.

[0031] The toilet bowl cavity of the toilet body 1 is provided with a bowl surface 5. On the bowl surface 5 is a water outlet 6, with the flushing orifice 41 and the air vent 42 respectively connected to the water outlet 6. The water outlet 6 is located at the far end of the water inlet 2 on the curved channel 3. The curved channel 3 directs the water flow from the water inlet 2 through the water outlet 6 to the bowl surface 5, which is bowl-shaped to aid in brushing and vortex formation. The bowl surface 5 is continuously connected to the toilet body 1, reducing dirt accumulation and facilitating cleaning.

[0032] During flushing, water flows from the reservoir to the water inlet 2 and enters the curved channel 3 via the water inlet 2. Then, the water flow splits into two parts: most of the water passes through the rinse orifice 41 to reach the water outlet 6, while a small part of the water and the air at the top of the curved channel 3 are expelled through the air vent 42. The purging of air inside the curved channel 3 by the air vent 42 helps to reduce collisions between water and air at the water outlet 6 during flushing, thus achieving a noise reduction effect.

[0033] The transition is smooth at the junction point between the curved channel 3 and the water inlet 2. The end of the curved channel 3 near the water inlet 2 is higher than that near the water outlet 6; the curved channel 3 gradually slopes down, thus facilitating the flow of water through the water outlet 6. The cross-section of the vertical plane on the side of the curved channel 3 near the water outlet 6 is smaller than that on the side near the water inlet 2. The gradual reduction of the cross-section of the vertical plane of the curved channel 3 accelerates the water flow as it exits through the water outlet 6.

[0034] On the side of said basin surface 5 away from the curved channel 3 is provided a flow guide platform 7, the flow guide platform 7 being continuously connected to the water outlet 6. The flow guide platform 7 extends along the curvature of the basin surface 5 and is continuously assembled with the basin surface 5. The flow guide platform 7 extends from the side near the water outlet 6 towards the side far from the water outlet 6, and the flow guide platform 7 gradually narrows and lowers. The flow guidance platform 7 serves to guide the flow of water flowing from the water outlet 6, to form a vortex along the surface of the bowl 5, slowing the fall of the water flow to allow the rinsing time of the surface of the bowl 5 to be extended.

[0035] The water outlet 6 is flattened, allowing the water flow to flow in a flattened manner and in close contact with the surface of the basin 5 at the water outlet 6, before passing through the flow guide platform 7. The The diversion through the flow guidance platform 7 allows the flattened water flow to form a vortex to completely rinse the surface of the basin 5.

[0036] The operating principle of a vortex flush toilet proposed by the present invention is as follows: during flushing, the water first flows from the tank to the water inlet 2 and then enters the curved channel 3 via the water inlet 2. The water flow then divides into two parts: the majority of the water passes through the flushing orifice 41, while a small portion of the water and the air at the top of the curved channel 3 are expelled through the air vent 42. The water flow is guided by the flow guide platform 7 after passing the water outlet 6, which allows the water to form a vortex to completely rinse the surface of the bowl 5 and flush away the excrement.

[0037] The present invention has been described in greater detail based on the specific embodiments above. However, it should be understood that the specific description herein shall not be construed as a limitation of the substance and scope of the present invention. Any modifications to the aforementioned embodiments by a person skilled in the art fall within the scope of the protection claimed by the present invention.
