Description

Technical Field

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

[0002] As consumers' awareness of energy conservation and environmental protection continues to deepen, the requirements for water consumption in the sanitary ware industry have become increasingly stringent, thinking that the less water used, the more satisfactory the flushing effect can be. Therefore, the national standard "GB / T31436-2015 Water-saving Sanitary Ware" has clear requirements that for nominal water consumption ≤ 4.0 liters, the maximum limit of full flushing water consumption for high-efficiency water-saving dual-flush toilets shall not exceed 5.0 liters, and the "artificial test body and paper ball" function test must be carried out. The reduction in water consumption has a great impact on the flushing performance of the toilet, especially the "artificial test body and paper ball" function test. The requirement of this function is also a pain point that many products on the market cannot achieve, especially water-saving toilets. Traditional toilets are classified according to the flushing method, including flushing type and siphon type. Among them, the flushing type relies entirely on the impact of water to discharge sewage, and the amount of water used can largely determine the flushing effect; and compared with the flushing type, the siphon type can achieve better flushing function by designing the pipeline structure to meet the requirements of using relatively less water to generate siphon. 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] Invention patent application CN115928848A discloses a toilet seat and toilet device, which is provided with a first brush ring flow channel, a second brush ring flow channel and a jet flow channel, the water inlet ends of the first brush ring flow channel and the jet flow channel are both connected to the water outlet end of the first water supply flow channel, and the water outlet end of the first brush ring flow channel is both connected to the pot surface; the water inlet end of the second brush ring flow channel is connected to the water outlet end of the second water supply flow channel, and the water outlet end of the second brush ring flow channel is connected to the pot surface. However, in the wall-mounted design, this design has a poor siphon effect and poor flushing effect due to its small size. Summary of the invention

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

[0005] The present invention 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 jetting channel; wherein the pot surface is formed with a buffer table surface located below the water surface cover so as to facilitate the entry of an artificial specimen into the sewage inlet; the sewage inlet connects the buffer table surface and the sewage discharge pipe, and the sewage inlet is of a structure that 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 turning portion that is higher than the sewage inlet; the water jetting channel is arranged above the pot surface to form a vortex flow at the pot surface for flushing, and can form a siphon effect at the sewage inlet; the jetting channel is arranged at the sewage inlet, and is suitable for flushing water in the direction of the sewage discharge pipe to provide a method for flushing the artificial specimen out of the turning portion.

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

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

[0009] Furthermore, the injection channel is provided with an injection hole in a strip shape, 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 discharge 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 specimen falls into the shallow water area, which is not easy to splash water. The buffer table in the shallow water area slides smoothly toward the sewage inlet, which is conducive to more artificial specimens entering the sewage inlet in strips, avoiding the artificial specimens from getting knotted 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 pipeline. The artificial specimen is affected by gravity, and the front end needs a greater impact force to climb the slope, so it is necessary to form a siphon as soon as possible during flushing. The structure of the present invention sets the injection hole right in the middle of the sewage inlet. When the specimen is full and falls to the bottom of the sewage inlet, due to the shape characteristics of the front half of the pipeline, the artificial specimen can enter the pipeline more easily. As the water level continues to rise and the injection hole provides a greater flushing force, a siphon is quickly generated to flush the waste away. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Combination Figures 1 to 7As shown, the present embodiment provides a high-efficiency water-saving wall-mounted toilet, comprising a toilet seat 1, wherein a pot surface 2, a sewage inlet 3, and a sewage discharge pipe 4 are formed in the toilet seat 1; further comprising a water jetting channel 6 and a jetting channel 5; wherein the pot surface 2 is formed with a buffer table surface 11 located below the water surface cover so as to facilitate the entry of an artificial specimen into the sewage inlet 3; the sewage inlet 3 connects the buffer table surface 11 and the sewage discharge pipe 4, and the sewage inlet 3 is of a structure that is wide at the top and narrow at the bottom; the sewage discharge pipe 4 is connected to the rear end of the sewage inlet 3 and is formed with a turning portion 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 flow at the pot surface 2 for flushing, and can form a siphon effect at the sewage inlet 3; the jetting channel 5 is arranged at the sewage inlet 3, and is suitable for flushing water toward the sewage discharge pipe 4 to provide a way to flush the artificial specimen out of the turning portion 41.

[0024] The jet channel 5 and the water jet channel 6 of the toilet seat 1 are connected with 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] Combination 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, and 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 to improve the flushing effect.

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

[0027] Combination 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, and the buffer table 11 is inclined toward the sewage inlet 3 to facilitate the entry of artificial specimens into the sewage inlet 3; specifically, a space for artificial specimens to enter is formed at the buffer table 11, which is narrow in front and wide in the back, and the space is pear-shaped to facilitate the entry of artificial specimens, and it is easy to produce 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 easy to splash water. The buffer table 11 in the shallow water area slides smoothly toward the sewage inlet 3, which is conducive to more artificial specimens entering the sewage inlet 3 in strips, avoiding the artificial specimens from tangling and clogging before the sewage inlet 3.

[0028] The sewage inlet 3 is wide at the top and narrow at the bottom, and has a rounded shape without gullies, and the bottom of the sewage inlet 3 is arc-shaped, which is convenient for artificial specimens to enter and helps to form a siphon. The sewage inlet 3 is connected to the rear end of the sewage inlet 3. The sewage discharge pipe 4 is formed with a bend 41 with a height higher than the sewage inlet 3. The sewage discharge pipe 4 is in a square shape from the sewage inlet 3 to the bend 41, and the pipe diameter gradually decreases; at the same time, the sewage discharge 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 hole 51 is 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 as to spray water 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 on the buffer table of the pot surface 2 through the falling position, slides smoothly into the sewage inlet 3, piles up and falls and sinks to the bottom of the sewage inlet 3; after starting the flushing switch, water flows out of the two water outlets of the upper brush circle 9 to form a rotating flushing brush, the water level continues to rise, and a siphon effect is formed; and then a greater flushing force is provided through the water outlet of the jet hole 51 to flush out the dirt. During normal use, the artificial specimen is mostly blocked between the sewage inlet 3 and the bend 41 of the sewage pipe 4. The artificial specimen is affected by gravity, and a greater impact force is required for the front end to climb the slope, so a siphon needs to be formed as early as possible during flushing. In this embodiment, the injection hole 51 is arranged at the center of the sewage inlet 3. When the specimen is full and falls to the bottom of the sewage inlet 3, the artificial specimen can enter the pipeline more easily due to the shape characteristics of the front half of the pipeline. As the water level continues to rise and the injection hole 51 provides a greater flushing force, a siphon is quickly generated to flush away the dirt.

[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 injection 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 belong to the protection scope of the present invention.

[0032] The above description of the drawings used in the implementation manner only illustrates certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without paying creative work.
