Description

Technical Field

[0001] The utility model relates to the technical field of bathroom products, in particular to a high-efficiency water-saving wall-mounted toilet. Background Art

[0002] As consumers become more aware of energy conservation and environmental protection, water usage requirements in the bathroom industry are becoming increasingly stringent, with the goal of achieving satisfactory flushing results with less water. Therefore, the national standard "GB / T31436-2015 Water-Saving Sanitary Ware" explicitly stipulates that for high-efficiency, water-saving dual-flush toilets with a nominal water consumption of ≤4.0 liters, the maximum full flush water consumption must not exceed 5.0 liters, and they must also undergo "artificial test piece and paper ball" functional testing. Reducing water consumption significantly impacts toilet flushing performance, particularly the "artificial test piece and paper ball" functional test. This requirement is a major pain point for many current products on the market, especially water-saving toilets. Traditional toilets are categorized by flushing method: flush-down and siphonic. Flush-down toilets rely entirely on the impact of water to dissipate waste, and water consumption largely determines flushing effectiveness. Siphonic toilets, on the other hand, utilize a pipe design that uses a relatively small amount of water to generate siphonic suction, resulting in better flushing performance. Because wall-mounted toilets are inherently smaller than traditional toilets, they have natural limitations in the design of the pot surface and the pipe structure.

[0003] Utility model patent application CN115928848A discloses a toilet seat and toilet device comprising a first brush ring flow channel, a second brush ring flow channel, and a jet flow channel. The water inlet of the first brush ring flow channel and the jet flow channel are both connected to the water outlet of the first water supply flow channel, and the water outlet of the first brush ring flow channel is both connected to the pot surface. The water inlet of the second brush ring flow channel is connected to the water outlet of the second water supply flow channel, and the water outlet of the second brush ring flow channel is connected to the pot surface. However, this design, when mounted on a wall, suffers from poor siphoning and flushing effects due to its small size. Utility Model Content

[0004] The utility model discloses a high-efficiency water-saving wall-mounted toilet, aiming to improve the above-mentioned problems.

[0005] The utility model adopts the following scheme:

[0006] A high-efficiency, water-saving, wall-mounted toilet comprises a toilet seat, wherein a pot surface, a sewage inlet, and a sewage discharge pipe are formed in the toilet seat; further comprising a water jetting channel and a jet channel; wherein a buffer table is formed between the pot surface and the sewage inlet; the sewage inlet connects the buffer table and the sewage discharge pipe, and the sewage inlet is wide at the top and narrow at the bottom; the sewage discharge pipe is connected to the rear end of the sewage inlet and is formed with a bend portion whose height is higher than that of the sewage inlet; the water jetting channel is arranged above the pot surface to form a vortex at the pot surface for flushing, and can form a siphon effect at the sewage inlet; the jet channel is arranged at the sewage inlet, and is suitable for flushing water toward the sewage discharge pipe to provide a method for flushing artificial specimens out of the bend.

[0007] Furthermore, a space for the artificial specimen to enter is formed on the buffer table, which is narrow in the front and wide in the back.

[0008] Furthermore, the buffer table is inclined toward the sewage inlet.

[0009] Furthermore, the injection channel is provided with an elongated injection hole, and the injection port of the injection hole is directly opposite to the middle of the sewage inlet.

[0010] Furthermore, the shape of the sewage pipe from the sewage inlet to the turning portion is a square shape that is wide at the top and narrow at the bottom, and the pipe diameter gradually decreases.

[0011] Furthermore, the sewage pipe extends to the sewage outlet, and the pipe diameter from the bend to the sewage outlet is circular, and the pipe diameter is smaller than the bend.

[0012] Furthermore, a brush ring is formed in the toilet seat above the pot surface, and the water jetting channel includes a first water outlet and a second water outlet arranged on the brush ring, and the first water outlet and the second water outlet are respectively arranged on both sides of the toilet seat to be used for spraying water in the same rotation direction in the toilet seat, thereby forming a vortex at the pot surface for flushing; the first water outlet and the second water outlet are connected to a water inlet channel.

[0013] Beneficial effects:

[0014] This solution has a buffer table on the pot surface, and the front end is a shallow water area. When using the toilet, the artificial specimens fall into the shallow water area, which is not easy to splash water. The buffer table in the shallow water area slides smoothly towards the sewage inlet, which is conducive to more artificial specimens entering the sewage inlet in strips, avoiding the artificial specimens from getting tangled and blocked before the sewage inlet. At the same time, the unique shape of the sewage inlet is conducive to the entry of waste, and the siphon effect can be formed faster to complete the flushing. Furthermore, since the blockage of artificial specimens is mostly between the sewage inlet and the S-bend inflection point of the pipe. The artificial specimens are affected by gravity, and a greater impact force is required to climb the front end. Therefore, a siphon needs to be formed as early as possible during flushing. The structure of this utility model sets the spray hole right in the middle of the sewage inlet. When the specimens are full and fall to the bottom of the sewage inlet, due to the shape characteristics of the front half of the pipe, the artificial specimens can enter the pipe more easily. As the water level continues to rise and the spray hole provides a greater flushing force, a siphon is quickly generated to flush the waste away. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Combine Figures 1 to 7As shown, this embodiment provides a high-efficiency water-saving wall-mounted toilet, including a toilet seat 1, in which a pot surface 2, a sewage inlet 3, and a sewage pipe 4 are formed; further comprising a water jetting channel 6 and a jet channel 5; wherein the pot surface 2 is formed with a buffer table 11 located below the water surface to facilitate the entry of artificial specimens into the sewage inlet 3; the sewage inlet 3 connects the buffer table 11 and the sewage pipe 4, and the sewage inlet 3 is wide at the top and narrow at the bottom; the sewage pipe 4 is connected to the rear end of the sewage inlet 3 and is formed with a bend 41 whose height is higher than that of the sewage inlet 3; the water jetting channel 6 is arranged above the pot surface 2 to form a vortex at the pot surface 2 for flushing, and can form a siphon effect at the sewage inlet 3; the jet channel 5 is arranged at the sewage inlet 3, and is suitable for flushing water toward the sewage pipe 4 to provide a way to flush the artificial specimen out of the bend 41.

[0024] The jet channel 5 and the water jet channel 6 of the toilet seat 1 are connected to a water inlet device, which can be a water tank or a water valve, etc., for user control to flush the toilet. The water inlet device is an existing mechanism and will not be described here.

[0025] Combine Figures 1 to 3 As shown, a receiving cavity is formed in the toilet seat 1, and the pot surface 2 is arranged at the lower part of the receiving cavity. A brush ring 9 is formed in the toilet seat 1 above the pot surface 2. The water jet channel 6 includes a first water outlet 7 and a second water outlet 8 arranged on the brush ring 9. The first water outlet 7 and the second water outlet 8 are respectively arranged on both sides of the toilet seat 1 to spray water in the same rotation direction in the toilet seat 1, thereby forming a vortex at the pot surface 2 for flushing; the first water outlet 7 and the second water outlet 8 are connected to a water inlet channel. Here, the brush ring 9 is arranged above the pot surface 2, and a flushing platform for water flow is formed in the receiving cavity. The flushing water jetted from the first water outlet 7 and the second water outlet 8 flows along the flushing platform and forms a spiral motion water flow in the receiving cavity, thereby forming a vortex at the pot surface 2. In this way, the surface of the receiving cavity can be flushed, thereby improving the flushing effect.

[0026] The artificial specimen in this embodiment may be the user's feces, tissues, or other debris thrown into the containing cavity by the user.

[0027] Combine Figures 1 to 7As shown, in the unflushed state, there is a certain water level in the toilet, and the water level can be at the height of the pot surface 2 to form a water cover. A buffer table 11 is provided between the pot surface 2 and the sewage inlet 3. The buffer table 11 is inclined toward the sewage inlet 3 to facilitate the entry of artificial specimens into the sewage inlet 3. Specifically, the buffer table 11 forms a space for artificial specimens to enter, which is narrow in front and wide in the back. The space is pear-shaped to facilitate the entry of artificial specimens and easily generate a siphon effect at the buffer table 11. The front end of the buffer table 11 is a shallow water area. When using the toilet, the artificial specimen falls into the shallow water area and is not easily splashed. The buffer table 11 in the shallow water area slides toward the sewage inlet 3, which is conducive to more artificial specimens entering the sewage inlet 3 in strips, avoiding the artificial specimens from getting tangled and blocked before the sewage inlet 3.

[0028] The sewage inlet 3 is wide at the top and narrow at the bottom, with a rounded shape and no grooves. The bottom of the sewage inlet 3 is arc-shaped, which facilitates the entry of artificial specimens and helps form a siphon. The sewage inlet 3 is connected to the rear end of the sewage inlet 3. The sewage pipe 4 has a bend 41 formed at a height higher than the sewage inlet 3. The sewage pipe 4 is square in shape from the sewage inlet 3 to the bend 41, and the pipe diameter gradually decreases. At the same time, the sewage pipe 4 extends to the sewage outlet 10, and the pipe diameter from the bend 41 to the sewage outlet 10 is circular, and the pipe diameter is smaller than the bend 41. The jet channel 5 is provided with a long strip-shaped jet hole 51, and the jet port of the jet hole 51 is directly facing the middle of the sewage inlet 3, that is, the water spraying direction of the jet hole 51 is toward the sewage inlet 3 and the sewage pipe 4, so that water is sprayed toward the middle of the sewage inlet 3 during flushing, to assist in flushing the artificial specimen into the sewage pipe 4, and to assist the artificial specimen to pass through the bend 41 to reach the sewage outlet 10. Under normal water test conditions, the artificial specimen falls onto the buffer table of the pot surface 2 through the drop position, slides smoothly into the sewage inlet 3, piles up and falls and sinks to the bottom of the sewage inlet 3; after the flushing switch is turned on, water flows out of the two water outlets of the upper brush ring 9, forming a rotary flushing brush, and the water level continues to rise, forming a siphon effect; then the water outlet of the jet hole 51 provides a greater flushing force to flush out the dirt. During normal use, due to the blockage of artificial specimens, most of them are between the sewage inlet 3 and the bend 41 of the sewage pipe 4. Artificial specimens are affected by gravity, requiring greater force to climb the slope at the front end. Therefore, a siphon must be formed as soon as possible during flushing. In this embodiment, the injection hole 51 is positioned directly in the center of the sewage inlet 3. When the specimens are fully loaded and fall to the bottom of the sewage inlet 3, the shape of the front half of the pipe allows the specimens to enter the pipe more easily. As the water level continues to rise and the injection hole 51 provides greater flushing force, a siphon is quickly generated to flush away the waste.

[0029] The water inlet of the injection channel 5 can be connected to the water inlet channel through a pipeline, or a water channel can be directly formed in the toilet seat 1 to connect to the injection channel 5 to realize water discharge.

[0030] This embodiment achieves a better flushing effect with less water through structural design of the shape of the pot surface 2, the shape of the sewage inlet 3, the shape of the sewage pipe 4, the diameter of the sewage pipe 4, the shape of the spray hole 51, etc., so as to realize the high efficiency and energy saving characteristics of the wall-mounted toilet and improve the user experience.

[0031] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.

[0032] The above description of the drawings used in the implementation manner only shows certain embodiments of the present invention and should not be regarded as limiting the scope.
