Description

Technical Field

[0001] This disclosure relates to toilets and individual urine and feces treatment systems. Background Technology

[0002] For human health and environmental protection, it is necessary to treat urine and feces discharged from homes. In areas lacking urine and feces treatment facilities, it is best to treat urine and feces individually in each household. Household urine and feces treatment devices are needed to treat urine and feces in individual homes. However, areas without proper urine and feces treatment facilities may be areas with water shortages and insufficient power supply. Considering this, household urine and feces treatment devices preferably consume as little electricity and water as possible. Furthermore, considering that household urine and feces treatment devices are used in the home, they need to be of a small size.

[0003] Sewage supplied to the toilet includes not only human excrement and urine, but also cleaning water and toilet paper. Sewage is a mixture of solids and liquids. For effective urine and feces treatment, the solids and liquids need to be treated separately. Separating the mixed solids and liquids is a necessary pretreatment step for separate solid and liquid processing. Summary of the Invention

[0059] Reference Figures 1 to 7 A toilet 10 may be provided. The toilet 10 may include a body 100, a collecting member 200, a blocking member 300, and a grinder 400. The body 100 can deliver a mixture of urine and feces. For example, the mixture of urine and feces may be a mixture of liquid urine and feces (e.g., urine), solid urine and feces (e.g., feces), toilet paper, and cleaning water provided by the user of the toilet 10. The body 100 can separate the mixture of urine and feces into liquid urine and feces and solid urine and feces. Liquid urine and feces may refer to the liquid portion of the mixture of urine and feces. For example, liquid urine and feces may include at least one of urine or cleaning water. Solid urine and feces may refer to the solid portion of the mixture of urine and feces. For example, solid urine and feces may include at least one of feces or toilet paper. The separation of the mixture of urine and feces will be described below.

[0060] The main body 100 may have a hollow cylindrical shape. The main body 100 may include an inner surface 110. The inner surface 110 may include a urine and feces conveying surface 112 and a urine and feces separating surface 114. The urine and feces conveying surface 112 and the urine and feces separating surface 114 may define a urine and feces conveying channel h. The urine and feces conveying surface 112 and the urine and feces separating surface 114 may be respectively disposed on the upper and lower parts of the main body 100. The upper and lower parts of the main body 100 may be sequentially arranged along a first direction DR1 parallel to the arrangement direction of the main body 100 and the collecting member 200. The urine and feces conveying surface 112 can receive mixed urine and feces from the user and convey the mixed urine and feces to the lower part of the main body 100. The urine and feces conveying surface 112 may extend along the periphery of the urine and feces conveying channel h. For example, the urine and feces conveying surface 112 may surround the urine and feces conveying channel h. The urine and feces conveying surface 112 may have a concave shape. For example, the distance 112d of the urine and feces conveying surfaces 112 may decrease in the first direction DR1. The distance 112d of the urine and feces conveying surfaces 112 may be the distance between two points of the urine and feces conveying surfaces 112 facing each other in a direction perpendicular to the first direction DR1 (e.g., the second direction DR2 or the third direction DR3). The distance 112d of the urine and feces conveying surfaces 112 may refer to the width of the urine and feces conveying channel h defined by the urine and feces conveying surface 112. The urine and feces conveying surface 112 may have a certain radius of curvature such that the mixed urine and feces have a suitable velocity, thereby being separated into liquid urine and feces and solid urine and feces on the urine and feces separation surface 114. For example, the minimum radius of curvature of the urine and feces conveying surface 112 can be between 105R and 195R. In this disclosure, R refers to the radius of curvature in millimeters (mm). When the minimum radius of curvature of the urine and feces conveying surface 112 is less than 105R, the mixed urine and feces are supplied to the urine and feces separation surface 114 too quickly, which may make it difficult to separate the mixed urine and feces into liquid urine and feces and solid urine and feces. When the minimum radius of curvature of the urine and feces conveying surface 112 is greater than 195R, a large amount of cleaning water may be required to provide sufficient cleaning power to convey the mixed urine and feces.

[0061] The urine and feces separation surface 114 can separate the mixed urine and feces descending along the urine and feces conveying surface 112 into liquid urine and feces and solid urine and feces. The urine and feces separation surface 114 can extend along the periphery of the urine and feces conveying channel h. For example, the urine and feces separation surface 114 can surround the urine and feces conveying channel h. In one example, the urine and feces separation surface 114 can separate the mixed urine and feces supplied from the entire area of ​​the urine and feces conveying surface 112 into liquid urine and feces and solid urine and feces. The urine and feces separation surface 114 can have a convex shape. Therefore, the inflection point IP of the inner surface 110 can be provided at the boundary between the urine and feces separation surface 114 and the urine and feces conveying surface 112. For example, the distance 114d between the urine and feces separation surfaces 114 can decrease and then increase in a first direction DR1. The distance 114d of the urine and feces separation surface 114 can be the distance between two points facing each other on the urine and feces separation surface 114 in a direction perpendicular to the first direction DR1 (e.g., the second direction DR2 or the third direction DR3). The distance 114d of the urine and feces separation surface 114 can refer to the width of the urine and feces conveying channel h defined by the urine and feces separation surface 114. The urine and feces separation surface 114 can have a radius of curvature for separating the mixed urine and feces into liquid urine and feces and solid urine and feces. For example, a first point P1 on the urine and feces separation surface 114 with the smallest distance 114d can have a radius of curvature of 21R to 39R. When the radius of curvature of the first point P1 is less than 21R or greater than 39R, solid urine and feces and liquid urine and feces may not be separated to the desired level. In one example, a second point P2, located between a first point P1 and an inflection point IP on the urine and feces separation surface 114, can have a radius of curvature of 42R to 79R. In another example, a third point P3, located between the first point P1 on the urine and feces separation surface 114 and the collecting member 200, can have a radius of curvature of 49R to 91R.

[0062] The portion between the first point P1 and the third point P3 can be referred to as the urine and feces separation zone SR. The mixed urine and feces can be separated into solid urine and feces and liquid urine and feces in the urine and feces separation zone SR. Solid urine and feces can fall from the urine and feces separation zone SR into the solid collection zone 220, which will be described below. For example, solid urine and feces can be separated from the urine and feces separation surface 114 at the first point P1. Liquid urine and feces can be further conveyed along the urine and feces separation surface 114 by surface tension and provided to the liquid collection zone 210 via the first point P1.

[0063] The collection member 200 can provide a liquid collection area 210 and a solid collection area 220. The collection member 200 may include a partition wall 230 separating the liquid collection area 210 and the solid collection area 220. The partition wall 230 may extend between the liquid collection area 210 and the solid collection area 220. The partition wall 230 may overlap with the body 100 in a first direction DR1. In one example, the surface of the partition wall 230 on the solid collection area 220 side may be aligned with a first point P1 of the urine and feces separation surface 114 in the first direction DR1. The distance 200d between the partition wall 230 and the urine and feces separation surface 114 can be determined such that solid urine and feces do not fall into the liquid collection area 210. For example, the distance 200d between the partition wall 230 and the urine and feces separation surface 114 may be 4 cm to 8 cm. Therefore, solid urine and feces, as well as liquid urine and feces, can be separated to the desired level.

[0064] Liquid collection area 210 can collect liquid urine and feces supplied from urine and feces separation surface 114. The side and lower surfaces of liquid collection area 210 can be defined by collection member 200. In other words, the side and lower surfaces of liquid collection area 210 can be covered by collection member 200. The upper part of liquid collection area 210 can be open. Liquid urine and feces can be supplied into liquid collection area 210 through the upper part of liquid collection area 210. From a first direction DR1 (i.e., from a downward view of toilet 10), liquid collection area 210 can have an annular shape. Therefore, liquid collection area 210 can accommodate liquid urine and feces supplied from the entire area of ​​urine and feces separation surface 114. Liquid transfer pipe LT can be connected to liquid collection area 210. Liquid transfer pipe LT can transfer liquid urine and feces 1 to a liquid treatment device (not shown) outside toilet 10.

[0065] Solid collection area 220 can collect solid urine and feces supplied from urine and feces separation surface 114, or directly through the urine and feces separation surface 114. Solid collection area 220 can be surrounded by liquid collection area 210. The side surfaces of solid collection area 220 can be defined by collection member 200. In other words, the side surfaces of solid collection area 220 can be covered by collection member 200. The upper part of solid collection area 220 can be open. Solid urine and feces can be supplied into solid collection area 220 through the upper part of solid collection area 220. Viewed from the first direction DR1, solid collection area 220 can be exposed through urine and feces transfer channel h surrounded by urine and feces separation surface 114.

[0066] A blocking member 300 may be provided on the lower surface of the solids collection area 220. The blocking member 300 may be provided between the solids collection area 220 and the grinder 400. The blocking member 300 may be openable and closable. When the blocking member 300 is closed, solid urine and feces may be retained in the solids collection area 220. When the blocking member 300 is open, solid urine and feces may pass through the solids collection area 220 to the grinder 400, which will be described below. The blocking member 300 may protect the user of the toilet 10 by preventing exposure of the grinder and may prevent objects other than urine and feces from being damaged by the grinder when objects fall into the toilet 10. Furthermore, the blocking member 300 may block odors from the solids treatment device (not shown) that processes solid urine and feces.

[0067] The grinder 400 may include multiple rotatable blades 420. Three blades 420 are shown, but this is only one example. In another example, there may be fewer or more than three blades 420. The grinder 400 can grind solid urine and feces. The grinder 400 may be connected to a solids delivery pipe ST. The solids delivery pipe ST can receive ground solid urine and feces from the grinder 400 and deliver the ground solid urine and feces to a solids treatment device (not shown) outside the toilet 10. In one example, the treatment efficiency of solid urine and feces can be improved by grinding the solid urine and feces and providing them to the solids treatment device (not shown).

[0068] Multiple cleaning nozzles 500 can be provided on the urine and feces conveying surface 112. For example, multiple cleaning nozzles 500 can be provided near the upper part of the urine and feces conveying surface 112. The multiple cleaning nozzles 500 can spray cleaning water onto the urine and feces conveying surface 112. The multiple cleaning nozzles 500 can adjust the spray direction of the cleaning water so that the cleaning water rinses while rotating along the inner surface 110 of the body 100. When the cleaning water rinses while rotating along the inner surface 110 of the body 100, the required cleaning force can be provided with a smaller amount of cleaning water compared to when the cleaning water flows downward without rotating along the inner surface 110 of the body 100. Therefore, water used in the toilet 10 can be saved.

[0069] A housing 600, a toilet seat 710, and a lid 720 may be provided. The housing 600 may surround the body 100, the collecting member 200, the blocking member 300, and the abrasive 400. The toilet seat 710 may be provided on the body 100 so that the user of the toilet 10 can sit on it. The lid 720 may be provided on the toilet seat 710 to cover or expose the toilet seat 710.

[0070] To effectively handle mixed urine and feces, liquid urine and feces, as well as solid urine and feces, need to be treated separately. The toilet 10 of this disclosure can separate mixed urine and feces into liquid urine and feces and solid urine and feces using only the urine and feces separation surface 114 and the collection member 200. Therefore, the toilet 10 of this disclosure is suitable for situations requiring direct treatment of mixed urine and feces. Situations requiring direct treatment of mixed urine and feces may include, for example, areas where large-scale urine and feces treatment facilities are not available for collecting and treating mixed urine and feces discharged from households.

[0071] According to this disclosure, there is no need for separation devices for separating mixed urine and feces into liquid urine and feces and solid urine and feces, nor for the power (e.g., electricity) required to operate such devices. Therefore, this disclosure can minimize the urine and feces treatment system and also reduce the power required to operate the urine and feces treatment system.

[0072] Figure 8 It is along Figure 1 The cross-sectional view taken by line I-I' shows... Figure 1 How to operate a toilet. Figure 9 It is along Figure 1 The cross-sectional view taken from line II-II' shows... Figure 1 How to operate a toilet. Figure 10 It is along Figure 1 The cross-sectional view taken from line III-III' shows... Figure 1 How to operate a toilet.

[0073] Reference Figures 8 to 10 The mixed urine and feces MM can be provided on the urine and feces conveying surface 112 (①). The mixed urine and feces MM can include liquid manure 1 and solid manure 2. For example, liquid urine and feces 1 can include urine and clean water. For example, solid urine and feces 2 can include feces and toilet paper. Liquid urine and feces 1 and solid urine and feces 2 can reach the urine and feces separation surface 114 through the urine and feces conveying surface 112 (②). For ease of illustration, in Figure 8 and Figure 9 In this process, liquid urine and feces 1 and solid urine and feces 2 move directly toward the urine and feces separation surface 114 without rotating. Because multiple cleaning nozzles 500 discharge cleaning water, which rinses while rotating, the liquid urine and feces 1 and solid urine and feces 2 can fall while rotating with the cleaning water. However, in some cases, solid urine and feces 2 may move to the urine and feces separation surface 114 without rotating, regardless of the flow of cleaning water. Figure 10 The image shows a clean water flow 3.

[0074] Solid urine and feces 2 and liquid urine and feces 1 can reach the urine and feces separation area SR (③) of the urine and feces separation surface 114. The urine and feces separation area SR can be the area in which solid urine and feces 2 and liquid urine and feces 1 are separated. For example, the urine and feces separation area SR can be Figure 5 and Figure 6 The area between the first point P1 and the third point P3 shown in the figure. Solid urine and feces 2 can fall from the urine and feces separation surface 114 into the solid collection area 220 (④). When the blocking member 300 is opened, solid urine and feces 2 can move to the grinder 400 (⑤). Solid urine and feces 2 can be finely ground by the grinder 400 and discharged to the outside of the toilet 10 (⑥).

[0075] Unlike solid urine and feces 2, liquid urine and feces 1 do not fall from the urine and feces separation surface 114 in the urine and feces separation area SR. Liquid urine and feces 1 can fall from the urine and feces separation surface 114 after advancing further along it (⑦). Liquid urine and feces 1 can move to the liquid collection area 210 (⑧). Liquid urine and feces 1 can be discharged to the outside of the toilet 10 through the liquid transfer pipe LT (⑨).

[0076] Through the above process, the toilet 10 of this disclosure can separate and collect solid urine and feces 2 as well as liquid urine and feces 1. Therefore, the treatment efficiency of urine and feces can be improved.

[0077] Figure 11 This is a block diagram of an individual urine and feces treatment system according to an example embodiment. For the sake of brevity, it is referenced in the following figures. Figures 1 to 10 Descriptions that are essentially the same will not be repeated.

[0078] Reference Figure 11 An individual urine and feces treatment system 1000 can be provided. The individual urine and feces treatment system 1000 may include a toilet 1100, a water tank 1200, a liquid handling device 1300, and a solids handling device 1400. The toilet 1100 can be compared with a reference... Figures 1 to 10 The toilet described is basically the same as toilet 10.

[0079] The water tank 1200 can supply cleaning water to the toilet 1100. The water tank 1200 can be connected to the toilet 1100 or disconnected from the toilet 1100.

[0080] The liquid treatment device 1300 can obtain liquid urine and feces from the toilet 1100. The liquid treatment device 1300 can generate clean water by purifying the liquid urine and feces. The liquid treatment device 1300 can supply clean water to the water tank 1200. The individual urine and feces treatment system 1000 of this disclosure uses clean water generated from liquid urine and feces, thereby saving water supplied from outside the individual urine and feces treatment system 1000.

[0081] Solid waste treatment device 1400 can obtain solid urine and feces from toilet 1100. Solid waste treatment device 1400 can treat solid urine and feces in various ways. For example, solid waste treatment device 1400 can dry and then incinerate solid urine and feces. In one embodiment, solid waste treatment device 1400 can dehydrate solid urine and feces obtained from toilet 1100 to obtain liquid and supply the liquid to liquid treatment device 1300.

[0082] The individual urine and feces treatment system 1000 disclosed herein can handle both liquid and solid urine and feces. Therefore, the individual urine and feces treatment system 1000 disclosed herein can be applied to environments where facilities for collecting and treating urine and feces are not available.

[0083] The above description of the embodiments of the technical concept of this disclosure provides examples of the technical concept of this disclosure. Therefore, the technical spirit of this disclosure is not limited to the above embodiments, and it is obvious that those skilled in the art can make many modifications and changes by combining and implementing the above embodiments within the technical spirit of this disclosure.
