The phosphorus removing agent adding part includes a main body, a phosphorus removing agent receiving port, a water inlet port, a water supply port, and a water overflow port, wherein a first top port and a second top port are located above a bottom collection area instead of above a bottom overflow area, so that the phosphorus removing agent added from the phosphorus removing agent receiving port and the cleaning water passed in from the water inlet port can fall into the bottom collection area instead of the bottom overflow area.

Description

Technical Field

[0001] This invention relates to a descaling agent addition unit for toilets, which enables the toilet to remove dirt deposits. This invention also relates to a descaling agent addition system. Background Technology

[0002] Water quality varies in different regions, and products are prone to dirt buildup over time. However, existing products rarely have the function or equipment to remove dirt buildup.

[0003] Removing deposits primarily targets the presence of various minerals in water, such as phosphorus and calcium. When water is heated, the temperature catalyzes these minerals, causing physical and chemical reactions that form deposits on the surface or bottom of the container. These mineral deposits have strong insulating properties, which is disadvantageous in applications requiring rapid water heating via thermal conductivity. This necessitates higher energy consumption and is not energy-efficient.

[0004] On the other hand, research shows that phosphorus in water is a major contributing factor to the deposition of minerals. Therefore, it is necessary to take measures to minimize the amount of phosphorus deposited in water systems over a long period.

[0005] Phosphorus removal agents are reagents that remove total phosphorus from wastewater by forming hydrophobic flocculation precipitates rich in characteristic groups. They operate on principles such as adsorption, coagulation, co-precipitation, and plasma exchange.

[0006] The purpose of removing deposited phosphorus is to periodically add a phosphorus remover to the water system. During the phosphorus removal process, the remover is added to the water inside the toilet's functional areas and flows through the bidet system components, thus cleaning the water system.

[0007] Therefore, there is an urgent need to develop a descaling agent addition part for toilets that does not affect the daily use of the toilet. Summary of the Invention

[0008] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a descaling agent addition part for toilets, which can easily add descaling agent during toilet maintenance without affecting the daily use of the toilet, and clean the dirt deposits in the toilet pipes and water outlet.

[0009] In a first example of the descaling agent addition section, the descaling agent addition section includes: a main body having a hollow receiving cavity, and a baffle provided at the bottom of the receiving cavity, the baffle dividing the bottom of the receiving cavity into a bottom accumulation area and a bottom overflow area; a descaling agent receiving port fluidly connected to an external descaling agent source, and fluidly connected to a first top port at the top of the receiving cavity of the main body; a water inlet fluidly connected to an external clean water source, and fluidly connected to a second top port at the top of the receiving cavity of the main body; and a water supply port fluidly connected to a device within the functional part of the toilet, the water supply port fluid... A first bottom port is connected to the bottom of the receiving cavity of the main body, the first bottom port being located in the bottom accumulation area; and an overflow outlet, the overflow outlet discharging into the basin portion of the ceramic part of the toilet bowl, the overflow outlet being fluidly connected to a second bottom port at the bottom of the receiving cavity of the main body, the second bottom port being located in the bottom overflow area, so that fluid in the bottom overflow area is discharged into the basin portion, wherein the first top port and the second top port are located above the bottom accumulation area rather than above the bottom overflow area, so that descaling agent added from the descaling agent receiving port and cleaning water introduced from the water inlet can fall into the bottom accumulation area rather than into the bottom overflow area.

[0010] In a second example of the phosphorus removal agent addition section, a first example may be included, wherein the first height of the baffle is set such that the height difference from the top of the baffle to the second top port of the inlet is greater than or equal to 1 inch, in order to prevent water from being contaminated by backflow.

[0011] In the third example of the phosphorus removal agent addition section, one or more of the first and second examples may be included. The first height of the baffle is set such that the height difference from the top of the baffle to the second top port of the water inlet is 33 mm, in order to prevent the water from being contaminated by backflow.

[0012] In the fourth example of the phosphorus removal agent addition section, one or more of the first to third examples may be included. The water supply outlet extends from the outside of the main body in a first horizontal direction, the overflow outlet extends from the outside of the main body in a second horizontal direction, the second horizontal direction is perpendicular to the first horizontal direction, and the baffle extends inside the main body in a third horizontal direction, and the angle between the third horizontal direction and the first horizontal direction is in the range of 30 degrees to 60 degrees, making full use of the space inside the main body.

[0013] In the fifth example of the descaling agent addition section, one or more of the first to fourth examples may be included, with the baffle configured to be adjacent to the second bottom port and parallel to the wall of the body including the second bottom port, facilitating design and manufacturing.

[0014] The present invention also provides a phosphorus removal agent addition system, which includes a phosphorus removal agent addition unit according to one aspect of the present invention.

[0015] In a first example of the descaling agent addition system, a descaling agent addition section is provided inside the functional section of the toilet; and a descaling agent injection port is provided on the upper shell portion of the functional section of the toilet, and the descaling agent injection port is sealed to the descaling agent receiving port of the descaling agent addition section.

[0016] In a second example of the descaling agent addition system, a first example may be optionally included, wherein the descaling agent addition system includes a dust cover that shields the descaling agent injection port for shielding the descaling agent injection port of the functional part.

[0017] In a third example of the descaling agent addition system, one or more of the first to second examples may be included. The descaling agent addition system includes a descaling agent container that is fluidly connected to a descaling agent injection port.

[0018] In a fourth example of the descaling agent addition system, one or more of the first to third examples may be included. The descaling agent injection port has a recess and also has a receiving opening protruding upward from the descaling agent injection port. The descaling agent container is in the form of a bottle with a duckbill valve inside the bottle mouth. During cleaning with added descaling agent, the descaling agent container is inverted, wherein the receiving opening at least partially enters the bottle mouth of the descaling agent container, opening the duckbill valve, so that the bottle mouth is in fluid connection with the descaling agent receiving port of the descaling agent addition unit.

[0019] In a fifth example of the descaling agent addition system, one or more of the first to fourth examples may be included, wherein the descaling agent container is in the form of an open cup and has a downwardly extending insertion port at the bottom of the descaling agent container, the insertion port being fluidly connected to the descaling agent injection port.

[0070] This invention primarily relates to the field of toilet manufacturing. In particular, it relates to the addition of a descaling agent to the water system of a toilet. Determining whether a descaling agent should be added, for example, due to local regulations or industry standards, is beyond the scope of this invention.

[0071] The term “fluid connection” as used in this article is intended to describe a direct or indirect fluid pathway from one component to another, so that fluid can flow from one component to another and vice versa.

[0072] The term “emission” as used in this article is intended to describe a unidirectional fluid path from one component to another, so that fluid can flow from one component to another, but cannot flow in the opposite direction.

[0073] The directional terms used herein, such as “vertical,” “horizontal,” “top,” “bottom,” “upper,” “lower,” “inner,” “inward,” “outer,” and “outward,” are used to assist in describing the orientation of the invention according to the embodiments illustrated in the figures. The directional terms are not absolute terms like up, down, horizontal, vertical, etc., and should not be construed as limiting the invention to any particular orientation.

[0074] The terms “including,” “having,” “comprising,” and variations thereof, as used herein, are intended as open-ended transitional phrases, terms, or words that require the presence of a specified component / step, but also allow for the presence of other components / steps.

[0075] In this invention, unless explicitly stated otherwise, the terms “first,” “second,” etc., are not intended to indicate any difference in order, position, quantity, or importance, but are merely used as labels to distinguish different positions or components.

[0076] The terms “approximately” and “roughly” can be used to include any numerical value that can vary without altering its fundamental function. Generally, the terms “approximately” and “roughly” can refer to plus or minus 10% of the number being referred to. When used with ranges, “approximately” and “roughly” also disclose a range defined by the absolute values ​​of the two endpoints; for example, “approximately 2 to approximately 4” also discloses a range “from 2 to 4”.

[0077] All ranges disclosed herein include the described endpoints and can be combined independently (e.g., the range "from 2 to 4" includes endpoints 2 and 4 as well as all intermediate values).

[0078] The numerical values ​​used herein should be understood to include the same numerical values ​​when reduced to the same number of significant digits, as well as numerical values ​​that differ from those determined by conventional measurement techniques of the type described in this application by an experimental error.

[0079] Finally, the numerical values ​​given in the various embodiments are merely examples and are not intended to limit the scope of the invention.

[0080] In the cleaning process of adding the phosphorus removal agent, the phosphorus removal agent addition unit 1 of the present invention does not introduce cleaning water again, but introduces cleaning water again after cleaning. The present invention provides a reasonable solution for effectively eliminating the precipitation of phosphorus-containing substances in the water circuit of the toilet's functional unit 3 caused by different water quality, and this solution can also prevent wastewater overflow and water source pollution.

[0081] In a non-limiting example, the phosphorus removal agent addition part 1 of the present invention includes a main body 10, the shape of which is not specifically limited in the present invention. For example, the main body 10 may be cylindrical, cuboid, etc., but the shape of the main body 10 is not limited to these.

[0082] The main body 10 has a hollow receiving cavity 11 for receiving air (as an air gap, which will be described in detail below), clean water introduced from an external clean water source, and phosphorus removal agent added from an external phosphorus removal agent source.

[0083] A baffle 12 is provided at the bottom of the receiving cavity 11, dividing the bottom of the receiving cavity 11 into a non-fluidly connected bottom accumulation area 13 and a bottom overflow area 14. The position of the baffle 12 is not specifically limited.

[0084] The baffle 12 is in the form of a sheet material, with its bottom sealed to the bottom of the main body 10, its top exposed inside the receiving cavity 11, and its two ends sealed to the walls of the main body 10.

[0085] In a non-limiting example, the descaling agent addition unit 1 of the present invention further includes a descaling agent receiving port 20, which can be fluidly connected to an external descaling agent source. The shape and position of the descaling agent receiving port 20 are not specifically limited.

[0086] The descaling agent receiving port 20 can be fluidly connected to the first top port 15 at the top of the receiving cavity 11 of the main body 10, that is, a fluid passage is established between the external descaling agent source and the receiving cavity 11. The shape of the first top port 15 is not specifically limited.

[0087] The first top port 15 is located at the top of the receiving cavity 11, allowing the descaling agent added from an external descaling agent source to enter the receiving cavity 11 of the main body 10 under the influence of gravity. Preferably, the first top port 15 is located above the bottom accumulation region 13 rather than above the bottom overflow region 14, so that the descaling agent added from the descaling agent receiving port 20 can fall into the bottom accumulation region 13 instead of entering the bottom overflow region 14.

[0088] In a non-limiting example, the phosphorus removal agent addition unit 1 of the present invention further includes a water inlet 30, which can be fluidly connected to an external clean water source. The shape and position of the water inlet 30 are not specifically limited.

[0089] The inlet 30 can be fluidly connected to the second top port 16 at the top of the receiving cavity 11 of the main body 10, that is, a fluid passage is established between the external clean water source and the receiving cavity 11. The shape of the second top port 16 is not specifically limited.

[0090] The second top port 16 is located at the top of the receiving cavity 11, allowing clean water from an external clean water source to enter the receiving cavity 11 of the main body 10 under the action of pipeline water pressure or gravity. Preferably, the second top port 16 is located above the bottom accumulation area 13 rather than above the bottom overflow area 14, so that the descaling agent added from the descaling agent receiving port 20 can fall into the bottom accumulation area 13 instead of entering the bottom overflow area 14.

[0091] In a non-limiting example, in accordance with EU industry standards, an air gap with a height difference of 1 inch or more is required to prevent water contamination due to backflow. Therefore, the first height h1 of the baffle 12 of the present invention is set such that, within the receiving cavity 11, the height difference from the top of the baffle 12 to the second top port 16 communicating with the water inlet 30 is greater than or equal to 1 inch (approximately 25.4 mm).

[0092] In a non-limiting example, the descaling agent addition unit 1 of the present invention further includes a water inlet 40, which can be fluidly connected to a device in the functional unit 3 of the toilet via a pipe, such as a pipe for a human body washing device, a pipe for a water heating device, etc. The shape and position of the water inlet 40 are not specifically limited.

[0093] The water inlet 40 can be fluidly connected to the first bottom port 17 at the bottom of the receiving cavity 11 of the main body 10, that is, a fluid passage is established between the device in the functional part 3 and the receiving cavity 11. The shape of the first bottom port 17 is not specifically limited.

[0094] The first bottom port 17 is disposed in the bottom gathering region 13 of the receiving cavity 11, allowing the fluid gathered in the bottom gathering region 13 to enter the device in the functional part 3.

[0095] In a non-limiting example, the phosphorus removal agent addition section 1 of the present invention further includes an overflow outlet 50, which can discharge into the basin portion 2a of the ceramic part 2 of the toilet bowl, i.e., flow away directly. The shape of the overflow outlet 50 is not specifically limited, but its position is limited to being at least above or inside the basin portion 2a.

[0096] The overflow port 50 can be fluidly connected to the second bottom port 18 at the bottom of the receiving cavity 11 of the main body 10, that is, the second bottom port 18 can discharge into the basin portion 2a. The shape of the second bottom port 18 is not specifically limited.

[0097] The second bottom port 18 is located in the bottom overflow area 14 of the receiving cavity 11, allowing fluid in the bottom overflow area 14 to be discharged into the basin portion 2a. This structural design facilitates the removal of excess water during normal use or during descaling operations. Optionally, the overflow outlet 50 discharges into the deodorizing port of the functional section 3.

[0098] In one non-limiting example, the descaling agent addition system of the present invention includes a descaling agent addition section 1. The descaling agent addition section 1 is preferably disposed within the functional section 3 of the toilet.

[0099] In a non-limiting example, the descaling agent addition system of the present invention includes a descaling agent injection port 120, which may be disposed on the upper shell portion 3a of the functional part 3 of the toilet. The shape of the descaling agent injection port 120 is not specifically limited in the present invention.

[0100] The descaling agent injection port 120 is sealed to the descaling agent receiving port 20 of the descaling agent adding section 1. Alternatively, the descaling agent injection port 120 can be located directly above the descaling agent receiving port 20 and the vertical projection of the descaling agent injection port 120 is completely located within the descaling agent receiving port 20, ensuring that all added descaling agent enters the descaling agent receiving port 20.

[0101] In a non-limiting example, the descaling agent addition system of the present invention includes a descaling agent container 110 as an external source of descaling agent, and the shape of the descaling agent container 110 is not specifically limited in the present invention. The descaling agent container 110 is fluidly connected to the descaling agent inlet 120.

[0102] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0103] The accompanying figure provides a coordinate system for reference, where the z-axis can be a vertical axis (e.g., parallel to the direction of gravity), the x-axis can be a horizontal axis (e.g., parallel to the horizontal direction), and the y-axis can be a longitudinal axis (e.g., the xy plane is parallel to the horizontal plane).

[0104] When referring to directions, a positive direction can indicate the direction of the arrows pointing towards the y, x, and z axes, while a negative direction can indicate the opposite direction of the arrows pointing towards the y, x, and z axes. A solid circle can represent arrows and axes facing towards the view or positively towards the view. An unfilled circle can represent arrows and axes facing away from the view or negatively towards the view.

[0105] Figure 1 A perspective view of the toilet of the present invention is shown schematically. The toilet mainly includes a ceramic part 2, a functional part 3, and a descaling agent addition part 1 of the present invention. As described above, the descaling agent addition part 1 is preferably disposed within the functional part 3 of the toilet. Figure 1 The ceramic part 2 is shown to include a basin part 2a, and the functional part 3 includes a base plate part 3b. The upper shell part 3a of the functional part 3 is not shown.

[0106] Figure 2 A perspective view of the phosphorus removal agent addition section 1 according to an embodiment of the present invention is shown schematically. It includes a main body 10, a phosphorus removal agent receiving port 20, a water inlet 30, a water supply port 40, and an overflow port 50.

[0107] In this embodiment, the main body 10 is shaped as a combination of half a cylinder and half a cuboid.

[0108] The descaling agent receiving port 20 is located at the top of half of the cuboid of the main body 10, and is positioned near the edge of half of the cuboid facing the negative x-axis. The first top port 15 is positioned near the edge of half of the cuboid facing the positive x-axis. This design creates a tortuous fluid path between the external descaling agent source and the receiving cavity 11. This allows for full utilization of space and a rational layout of the injection ports within a limited space.

[0109] The inlet 30 is located at the top of the semi-cylindrical part of the main body 10. The inlet 30 is connected to an external clean water source at one end via a "gate" shaped pipe, and to the second top port 16 of the receiving cavity 11 at the other end. This arrangement can prevent the fluid in the receiving cavity 11 from accidentally flowing to the external clean water source.

[0110] In this embodiment, the requirement of air isolation is taken into consideration. The first height h1 of the baffle 12 is set such that the height difference from the top of the baffle 12 to the second top port 16 of the water inlet 30 in the receiving cavity 11 is 33 mm, so as to prevent residual phosphorus removal agent in the water path from contaminating the source of clean water.

[0111] In this embodiment, the water inlet 40 extends from the outside of the main body 10 in a first horizontal direction x, that is, along the positive x-axis. The overflow outlet 50 extends from the outside of the main body 10 in a second horizontal direction y, that is, along the positive y-axis. The second horizontal direction y is perpendicular to the first horizontal direction x, and the first horizontal direction x and the second horizontal direction y define a horizontal plane.

[0112] Figure 3 schematically shown Figure 2 Top perspective view of the phosphorus removal agent addition section 1.

[0113] In this embodiment, the baffle 12 extends within the main body 10 in a third horizontal direction x1, wherein the third horizontal direction x1 lies in a horizontal plane defined by the first horizontal direction x and the second horizontal direction y. Optionally, the angle θ between the third horizontal direction x1 and the first horizontal direction x can be in the range of 15 degrees to 75 degrees, preferably in the range of 30 degrees to 60 degrees, and more preferably in the range of 45 degrees.

[0114] In an alternative embodiment not shown, the baffle 12 may also be configured parallel to the wall of the body 10 including the second bottom port 18 and adjacent to the second bottom port 18, i.e., configured close to the second bottom port 18, so that the bottom overflow area 14 of the bottom of the receiving cavity 11 of the body 10 is as small as possible.

[0115] Figure 4 schematically shown Figure 2 Top perspective view of the phosphorus removal agent addition section 1.

[0116] The descaling agent receiving port 20 is located at the top of half of the cuboid of the main body 10. The descaling agent receiving port 20 is rectangular in shape with a rounded curve and a rounded protrusion. The first top port 15 is triangular in shape with a rounded curve, but the cross-sectional area of ​​the descaling agent receiving port 20 is larger than that of the first top port 15. The first top port 15 is located below the descaling agent receiving port 20 and is offset towards the negative y-axis and the positive x-axis. This makes the fluid passage between the external descaling agent source and the receiving cavity 11 tortuous, thus making full use of the space and completing a reasonable layout of the injection port in a limited space.

[0117] Figure 5 schematically shown Figure 3 A side sectional view of the dephosphorizing agent addition section 1.

[0118] Combination Figure 2-5It can be clearly seen that the first top port 15 and the second top port 16 are located above the bottom collection area 13 rather than above the bottom overflow area 14, so that the descaling agent added from the descaling agent receiving port 20 and the cleaning water introduced from the water inlet 30 can fall into the bottom collection area 13 instead of the bottom overflow area 14, so as not to be wasted by being discharged from the bottom overflow area 14 into the basin part 2a of the toilet.

[0119] Figure 6 A partial top perspective view of a phosphorus removal agent addition system according to an embodiment of the present invention is shown schematically.

[0120] The descaling agent addition system of the present invention includes a descaling agent injection port 120, which is disposed on the upper shell portion 3a of the functional part 3 of the toilet. The descaling agent injection port 120 may have a recessed portion 121, see Figure 7 .

[0121] Furthermore, the descaling agent addition system of the present invention may include a dust cover 130 that shields the descaling agent injection port 120, see Figure 8 .

[0122] In one embodiment, the dust cover 130 may be in the form of a knob, having a handle on top and a thread on the lower outer periphery, and the thread engaging with a thread (not shown) in the recess 121 of the descaling agent injection port 120 of the toilet's functional part 3.

[0123] In one embodiment, the dust cover 130 may be in the form of a plug made of elastic material, having dimensions that mate with the recess 121 and are capable of blocking the descaling agent injection port 120.

[0124] In addition, the descaling agent injection port 120 also has a receiving opening 122 that protrudes upward from the descaling agent injection port 120.

[0125] Figure 9 schematically shown Figure 6 A side view of the dephosphorizing agent container 110 of the dephosphorizing agent addition system of an embodiment.

[0126] In this embodiment, the descaling agent container 110 is in the form of a bottle, and has a duckbill valve 111 inside the bottle mouth, which prevents the fluid in the descaling agent container 110 from overflowing when no descaling agent is added.

[0127] During the addition of the descaling agent, the descaling agent container 110 is inverted, with the neck of the bottle at least partially disposed in the recess 121 of the descaling agent injection port 120, and the protruding receiving opening 122 at least partially entering the bottle mouth of the descaling agent container 110, opening the duckbill valve 111, so that the descaling agent container 110 is in fluid connection with the descaling agent receiving port 20 of the descaling agent adding part 1.

[0128] The dephosphorizing agent container 110 uses the principle of a water dispenser. The liquid in the bottle flows automatically into the dephosphorizing agent inlet 120 under the action of air pressure, and then flows into the receiving cavity 11 of the dephosphorizing agent adding part 1.

[0129] Figure 10 , 11 Schematic illustration Figure 9 The working principle of the dephosphorizing agent container 110.

[0130] like Figure 10 As shown, when the water level in the inverted descaling agent container 110 is higher than the receiving opening 122 of the descaling agent inlet 120, the liquid in the bottle-shaped descaling agent container 110 will not flow out under atmospheric pressure.

[0131] like Figure 11 As shown, when the water level in the inverted descaling agent container 110 is lower than the bottle opening of the bottle-shaped descaling agent container 110, air enters the descaling agent container 110, and under atmospheric pressure, the liquid in the descaling agent container 110 will continue to flow out.

[0132] Figure 12 A side view of a descaling agent container 110 of a descaling agent addition system according to another embodiment of the present invention is shown schematically. Figure 13 schematically shown Figure 12 A side sectional view of the insertion part of the descaling agent container.

[0133] The descaling agent container 110 is in the form of an open cup, and has a downwardly extending insertion port 112 at the bottom corner of the cup. The protruding insertion port 112 can prevent accidental contact. Preferably, the insertion port 112 is located on the bottom edge of the descaling agent container 110, and more preferably at the corner. This arrangement is more conducive to the stability of the descaling agent container 110 when placed on a flat surface compared to placing the insertion port in the center of the bottom.

[0134] Figure 14 schematically shown Figure 12 A side sectional view of the insertion portion of the descaling agent container 110.

[0135] The insertion port 112 contains a piston 113, a spring 114, and a sealing ring 115. Before insertion, the spring 114 applies a downward force, and the piston 113 and the sealing ring 115 keep the insertion port 112 sealed under the action of the spring 114 to prevent fluid leakage from the cup of the dephosphorizing agent container 110.

[0136] Figure 15 schematically shown Figure 12 A side sectional view of the insertion portion of the descaling agent container 110 during the addition of the descaling agent. Figure 16 schematically shown Figure 12 A partial top-view perspective view of the dephosphorizing agent injection port 120 of the dephosphorizing agent addition system.

[0137] In this example, the dephosphorizing agent injection port 120 has a hollow receiving tube 123 that protrudes upward (in the positive z-axis direction) and does not extend beyond the top surface of the upper shell portion 3a of the functional part 3.

[0138] During the addition of the descaling agent, the insertion port 112 is fluidly connected to the descaling agent injection port 120. When the cup of the descaling agent container 110 is inserted into the insertion port 112, the piston 113 is pushed up by the four protrusions 123a at the center of the receiving tube 123 of the descaling agent injection port 120, as... Figure 16 As shown, the fluid in the phosphorus agent container 110 can flow smoothly into the phosphorus agent injection port 120.

[0139] Preferably, the receiving tube 123 can be made of rubber, which can easily form a seal with the insertion port 112 to prevent water leakage.
