Description

Ultra-saving toilet with trap assembly

[0001] The present invention relates to an ultra-water-saving toilet capable of effectively discharging waste from a toilet with a small amount of water, and more specifically, to an ultra-water-saving toilet in which a trap for moving water and waste is assembled into a toilet, and a trap is assembled so as to effectively prevent water from leaking from the trap assembled into the toilet.

[0002] In general, a toilet is configured to support a user in a seated position, and includes a toilet body with a bowl formed to temporarily receive waste from urination or defecation, and a water tank located on one side of the toilet body, which stores water for washing away waste temporarily received in the bowl.

[0003] These toilets allow the user to urinate or defecate while seated, which is not only comfortable, but also allows the water in the water tank to immediately discharge waste from the bowl into the sewage pipe connected to the toilet body after urination or defecation, making it hygienic to dispose of waste after urination or defecation.

[0004] However, conventional toilets have the problem of high water consumption when used, as the entire 12 to 15 liters of water stored in the water tank is discharged into the bowl of the toilet body after performing a task such as urination or defecation.

[0005] To solve this problem, an improved toilet that can control the amount of water discharged from the water tank after use has been proposed, as disclosed in Korean Patent Publication No. 10-2010-0095110 (publication date: August 30, 2010).

[0006] These improved toilets can reduce water consumption compared to regular toilets by selectively operating a pair of buttons on the outside of the tank to discharge approximately 6-7 liters of water stored in the tank after defecation and to discharge approximately 3-4 liters of water stored in the tank after urine disposal.

[0007] However, a trap part is formed in the discharge passage provided in the lower part of the toilet body, and this trap part is always filled with air. Therefore, when discharging waste through the discharge passage, there is a problem in that the air in the trap part significantly interferes with the discharge, making it difficult to discharge waste smoothly.

[0008] For the above reasons, the field is attempting to develop a water-saving toilet that can control the amount of water discharged from the reservoir to the toilet body for waste disposal in the toilet body, while minimizing interference with discharge caused by air filled in the trap section and enabling smooth discharge of waste with a small amount of water. However, satisfactory results have not been achieved to date.

[0009] Accordingly, the applicant has applied for and received registration for an ultra-water-saving toilet through application number 10-2020-0007279.

[0010] However, when using these ultra-low-flow toilets, while a significant reduction in water usage can be expected, when using the toilet, various foreign substances are included in the waste, and these foreign substances frequently get caught in the trap. In such cases, it is possible to clean them with the help of experts from related companies, but it inevitably takes a lot of time and money, and in cases where the foreign substances are seriously caught in the trap, there is the inconvenience of having to replace the toilet body, which takes even more time and money.

[0066] The configuration and operation of a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0067] This is intended to explain in detail to a degree that a person having ordinary knowledge in the technical field to which the present invention pertains can easily practice the contents of the present invention, and does not mean that the technical idea and scope of the present invention are limited thereby.

[0068] In addition, when adding reference signs to components of each drawing, it should be noted that identical components are indicated with the same signs as much as possible even if they are shown in different drawings, and terms specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator, and the definitions of these terms should be determined based on the contents throughout this specification.

[0069] Additionally, throughout the specification, when a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise specifically stated.

[0070] First, the configuration of the ultra-saving toilet in which the trap according to the present invention is assembled can be broadly divided into a toilet body comprising a bowl part and a trap part coupled to the bowl part, a water storage tank installed on one side of the toilet body, a water-saving tank installed inside the water storage tank, a water discharge device, and an air movement member having one side connected to the trap part and the other side connected to the water-saving tank, and the configuration of the present invention divided in this way will be described in more detail with reference to the drawings provided as examples.

[0071] First, the toilet body (100) is

[0072] As illustrated in Fig. 1, it may be configured to include a bowl part (110) having a hemispherical space so that water or waste can be accommodated inside while the upper part is open, and a trap part (120) that is separately configured to connect a discharge hole (111) formed inside the bowl part (110) to a wastewater pipe and is coupled to the outside of the bowl part (110). A seating seat for a user to sit on may be provided on the upper part of the bowl part (110), and the open upper part of the bowl part (110) may be opened and closed by a cover.

[0073] This toilet body (100) can be made of a material such as ceramic, synthetic resin, or metal, and, if necessary, the inner surface of the bowl part (110), the inner surface of the trap part (120), or both the inner surface of the bowl part (110) and the inner surface of the trap part (120) can be coated with nanomaterials to reduce surface tension, thereby promoting the movement of waste passing through the inner surface, thereby reducing the consumption of water used for waste treatment.

[0074] And, as shown in Fig. 8, the trap part (120) is connected to the discharge hole (111) of the bowl part (110) and connects the extension part (112) formed in the shape of a trap from the outer surface of the bowl part (110) to the sewage pipe.

[0075] This trap section (120) can be configured with an upwardly inclined section (121) as shown in FIG. 11 while connected to an extension section (112), a straight section (122) that bends downward from this inclined section (121), and a trap section (123) that is roughly 'U' shaped and bends upward again from this straight section (122) and then bends downward again to connect to a sewage pipe, and can double-block odors coming up from the sewage pipe through sealing water that accumulates inside the extension section (112) and inside the trap section (123).

[0076] In addition, one side of the trap section (120) is formed with a fitting section (121a) in the form of an expanded tube at the end of the inclined section (121), so that the fitting section (121a) is fitted and fixed to the extension section (112) of the bowl section (100), and in order to maintain airtightness, silicone may be applied to the outer circumference of the fitting section (121a) or the inner circumference of the extension section (112) or both together with packing, and the fitting section may be fixed.

[0077] And the other end of the trap section (120) is formed with an installation section (123a) including a packing at the end of the trap section (123) so that it can be fitted and connected to the sewage pipe, and a flange (123b) is formed at both ends of this installation section (123a), so that this flange (123b) can be additionally fixed through a fixing member installed inside the end portions on both sides of the toilet body (100) while being fixed around the sewage pipe.

[0078] Such a trap section (120) can be manufactured through various molding methods, and can be configured as an integral body made of one body, but can also be configured as two molds that are then joined to face each other, as shown in FIGS. 12 to 14.

[0079] That is, as shown in Fig. 12, the trap section (120) is composed of a first mold (120a) and a second mold (120b) whose external shapes are symmetrical to each other, and the first mold (120a) and the second mold (120b) can be joined while facing each other, and the joining method can be such that the overlapping edges of the first mold (120a) and the second mold (120b) are joined by fastening them with bolts and nuts, and at this time, packing can be installed between the overlapping edges to maintain airtightness.

[0080] In another joining method, the first mold (120a) and the second mold (120b) are joined facing each other, and an adhesive material is applied to the edges of the first mold (120a) and the second mold (120b) to join them.

[0081] Another method of joining is to join the first mold (120a) and the second mold (120b) facing each other, and to join the edges of the first mold (120a) and the second mold (120b) through high-frequency fusion.

[0082] And as another joining method, as in the embodiment of the present invention, the first mold (120a) and the second mold (120b) are joined while facing each other, but the edges of the first mold (120a) and the second mold (120b) can also be joined through ultrasonic vibration welding.

[0083] For reference, this ultrasonic vibration welding applies frictional heat to the contact edges of the first mold (120a) and the second mold (120b) by using high-frequency mechanical vibration, and since this vibration is generally generated at a frequency in the ultrasonic range (generally 20 kHz or higher) that exceeds the human hearing range, the inner surface of the edges can be melted by the frictional heat, allowing them to be joined to each other.

[0084] The present invention uses the ultrasonic vibration fusion method of a first mold (120a) and a second mold (120b), thereby precisely controlling the amplitude and frequency of vibration to precisely heat only the edges of the first mold (120a) and the second mold (120b), thereby preventing thermal deformation or damage to other areas than the edges, and since no additional consumables such as adhesives, solvents or fasteners are required for fusion, the joint area can be made to look good, can be manufactured in an environmentally friendly manner, and can improve productivity through rapid fusion.

[0085] In addition, in order to effectively fuse the first mold (120a) and the second mold (120b) by ultrasonic vibration, a fusion protrusion (126) protruding to a predetermined height is formed at the center of the inner surface of the rim of the first mold (120a), and a fusion surface (127) that can be in contact with the fusion protrusion is formed at the center of the inner surface of the rim of the second mold (120b). Accordingly, when the rims of the first mold (120a) and the second mold (120b) are fused by ultrasonic vibration, the fusion protrusion (126) formed at the rim of the first mold (120a) melts on the fusion surface (127) formed at the rim of the second mold (120b), so that the inner surfaces of the rims of the first mold (120a) and the second mold (120b) can be fused to each other.

[0086] Meanwhile, when a burr is generated during the process of melting and fusing the fusion projection (126) and the fusion surface (127), a part of the burr may leak inside or outside the edges of the first mold (120a) and the second mold (120b) that are fused, and such leakage of the burr inside the edges may hinder the smooth progress of contaminants, etc. moving through the inside of the trap part (120), and leakage of the burr outside the edges may damage the appearance of the trap part (120), which may cause a decline in marketability.

[0087] Accordingly, by forming a burr receiving groove (128) of a predetermined depth on both sides facing each other with the fusion surface (127) as the center on the inner surface of the rim of the second mold (120b), burrs that come off the rim are received in the burr receiving groove (128), thereby preventing burr leakage inside or outside the rim.

[0088] However, since this water receiving groove (128) rather becomes a passage for water located inside the trap part (120), especially in a part of the trap part (120) where water is accumulated, a part where a lot of water moves, or a part where water moves slowly, water easily flows into the water receiving groove (128) located in a part that comes into contact with water, and then moves along the water receiving groove (128), the water that was moving along the water receiving groove (128) may leak through a gap caused by tolerance or deformation of the parts at the fused edges of the first mold (120a) and the second mold (120b). In some cases, an odor may also be emitted, which may cause a problem that requires repeated inspection or replacement of the trap part (120).

[0089] Accordingly, the present invention forms partitions (129) at predetermined intervals along the water receiving groove (128) so as to block the movement of water along the water receiving groove (128), and forms them over the entire water receiving groove (128), or forms them only in limited areas that come into contact with water, such as areas where water accumulates, areas where a lot of water moves, or areas where water moves slowly, inside the trap section (120), as shown in FIG. 14, so that even if water moves to the water receiving groove (128), the movement of water is gradually blocked by the partitions (129), thereby preventing water from leaking or odor from being emitted when a gap is created in the fused edges of the first mold (120a) and the second mold (120b) due to tolerances of the parts, deformation during the manufacturing process, or use.

[0090] The water tank (200) is

[0091] As illustrated in FIGS. 1 and 8, it is installed at the upper rear portion of the toilet body (100) described above, and a space of a predetermined size is provided so that a certain amount of water can be stored inside, and a hole (210) connected to the bowl part (110) is formed on the bottom surface inside, so that water in the water storage tank (200) can move to the bowl part (110) through this hole (210).

[0092] The hole (210) formed in the water storage tank (200) can be opened by the operation of the water discharge device (400) which will be described in detail later, and this water discharge device (400) can be connected to a lever installed on the outer surface of the water storage tank (200) and operated by the operation of the lever.

[0093] In the water storage tank (200), an inlet pipe (not shown in the drawing) connected to an external water pipe is installed so that water can be filled inside, and a water level control device (not shown in the drawing) can be provided together with this inlet pipe so that the water level filled inside the water storage tank (200) can be controlled.

[0094] The water saving tank (300) is

[0095] A certain amount of water is stored by receiving water filled in the water tank (200) installed inside the water storage tank (200) described above, and the water stored in the water-saving tank (300) can be moved to the bowl part (110) according to the operation of the water discharge device (400).

[0096] As an example, as illustrated in FIGS. 2 and 3, the water tank (300) has a first storage section (310) formed in the center, which has an open upper surface and a hole (311) formed on the inner bottom surface so as to be connected to the opening (210) of the water tank (200), and a second storage section (320) formed around the outer periphery of the first storage section (310) through a partition wall (330), and a communication hole (331) may be formed at the bottom of the partition wall (330) so that the first storage section (310) and the second storage section (320) can be connected to each other and water can move.

[0097] An inlet (340) may be formed on the bottom surface of the water saving tank (300) so that water from the water storage tank (200) can be filled into the first storage section (310) and the second storage section (320) of the water saving tank (300). One such inlet (340) may be formed, or a plurality of such inlets may be formed so that water can be effectively filled into the first storage section (310) and the second storage section (320) by being distributed over the bottom surface.

[0098] The inlet (340) can control the amount of water moving into the water-saving tank (300) by adjusting its diameter or number, and when it is designed so that a larger amount of water than the set amount flows into the water-saving tank (300) through the inlet (340) when the water in the water-saving tank (300) flows out to the bowl part (110) according to the operation of the water discharge device (400), as the water flowing into the water-saving tank (300) through the inlet (340) increases, the water flowing out together to the bowl part (110) increases, so the amount of water used for waste treatment can be increased, and relatively, as the time for filling the water-saving tank (300) with water is shortened, the time required for the water discharge device (400) to re-operate can be reduced.

[0099] In addition, when the water in the water-saving tank (300) is designed to be fed into the water-saving tank (300) in an amount less than the set amount through the inlet (340), when the water in the water-saving tank (300) flows out to the bowl part (110) due to the operation of the water discharge device (400), the amount of water flowing into the water-saving tank (300) through the inlet (340) decreases, and the amount of water that flows out together to the bowl part (110) is reduced, so that the amount of water used for waste treatment can be reduced. In addition, as the time for filling the water-saving tank (300) with water increases relatively, the time required for the water discharge device (400) to operate again can increase.

[0100] Therefore, by appropriately adjusting the size of the water-saving tank (300), the diameter of the hole (311) formed in the water-saving tank (300), the diameter of the perforation (210) formed in the water-saving tank (300), the time for the perforation (210) to open and close depending on the operation of the water discharge device (400), and the diameter and number of the inlet ports (340) to design, the amount of water discharged to the bowl (110) and the time required for the water discharge device (400) to be re-operated can be provided in an appropriate form by taking into consideration the user's needs, installation environment and conditions, and circumstances.

[0101] Meanwhile, the amount of water flowing out of the bowl part (110) is determined by the size of the water-saving tank (300), the diameter of the hole (311) formed in the water-saving tank (300), the diameter of the perforation (210) formed in the water-saving tank (300), and the diameter and number of the inlet (340). Since this amount of water is determined in advance during the manufacturing process of the toilet, the user of the toilet cannot adjust the amount of water to a desired amount according to needs or the installation environment and conditions.

[0102] Accordingly, the present invention provides a control means capable of controlling the amount of water flowing out of the bowl portion (110) during the use of a toilet as needed, and as an example of such a control means, an auxiliary inlet (350) is formed in a water-saving tank (300), and by controlling the opening and closing amount of the auxiliary inlet (350), the amount of water flowing into the water storage tank (200) is controlled, thereby controlling the amount of water flowing out of the bowl portion (110) as needed.

[0103] That is, as shown in FIG. 4, an auxiliary inlet (350) is formed to penetrate the surface of the water-saving tank (300) in a square shape, and guide guides (351) are formed on the back of the water-saving tank (300) so as to face each other on both sides of the auxiliary inlet (350), and the shutter member (360) is configured to slide up and down while being inserted between these guide guides (351), so that the amount of water moving to the second storage unit (320) through the auxiliary inlet (350) can be controlled by the up and down sliding operation of the shutter member (360) while controlling the opening and closing amount of the auxiliary inlet (350).

[0104] Here, the auxiliary inlet (350) is formed with an elastic protrusion (352) on the upper end of the guide guide (351) so that the opening and closing amount can be adjusted in steps, and a plurality of catching grooves (361) are formed on both sides of the shutter member (360) so that the elastic protrusions (352) of the guide guide (351) can be selectively caught and fixed along the longitudinal direction, so that the opening and closing amount of the auxiliary inlet (350) can be easily and accurately adjusted as the shutter member (360) is raised and lowered in steps along the guide guide (351).

[0105] In addition, by installing a marking such as a scale on the outer surface of the shutter member (360), the amount of opening and closing of the auxiliary inlet (350) according to the up and down sliding of the shutter member (360) can be more accurately determined through the marking of the shutter member (360).

[0106] In addition, when the water saving tank (300) is installed in the water storage tank (200) and the shutter member (360) must be operated while submerged in water, the color of the shutter member (360) can be configured to be different from the color of the water saving tank (300) so that the position of the shutter member (360) can be easily recognized, and luminous paint or the like can be applied so that it can be easily identified in a dark environment.

[0107] Accordingly, for example, when the shutter member (360) is lowered to block the auxiliary inlet (350), water in the water storage tank (200) flows into the water-saving tank (300) only through the inlet (340) formed on the bottom surface of the water-saving tank (300), so that a small amount of water can be used in a water-saving manner, and when the shutter member (360) is raised to open the auxiliary inlet (350), water in the water storage tank (200) flows in together through the inlet (340) formed on the bottom surface of the water-saving tank (300) and the opened auxiliary inlet (350), so that a larger amount of water can be used in a general manner rather than in a water-saving manner.

[0108] The amount of water used can be adjusted according to the degree of opening of the auxiliary inlet (350), and it is preferable that the auxiliary inlet (350) and the shutter member (360) be formed at the bottom of the water-saving tank (300) so that water in the water storage tank (200) can easily flow into the water-saving tank (300), and the water-saving tank (300) may be configured with multiple units as needed.

[0109] Meanwhile, the water-saving tank (300) may be composed of a single body, but for the convenience of manufacturing and cleaning and maintenance of the inside, it may be composed of an upper and lower part that are divided into two parts and assembled together as shown in FIGS. 2 and 3.

[0110] In addition, the water-saving tank (300) may have a connecting portion (321) formed protrudingly on the upper side to communicate with the second storage portion (320), and this connecting portion (321) is connected to the air movement member (500) described in detail later, so that the air moved through the air movement member (500) is accurately and quickly moved vertically downward from the upper side of the second storage portion (320), thereby effectively promoting pressurization of the water in the second storage portion (320) by the air.

[0111] In addition, when the hole (311) of the water tank (300) is connected to the passage (210) of the water tank (200), a rubber packing may be installed together to maintain airtightness.

[0112] The water discharge device (400) is

[0113] It is installed in the water-saving tank (300) described above, and by operating the lever to open and close the hole (311) of the water-saving tank (300), it controls the movement of water stored in the water-saving tank (300) to the bowl part (110).

[0114] Specifically, as shown in FIG. 2, the water discharge device (400) is installed in the first storage section (310) of the water-saving tank (300), and the upper side of the cylindrical body (410) is connected to a lever installed on the outside of the water storage tank (200) through a connecting means (not indicated in the drawing), and the lower side of the cylindrical body (410) is connected to a hole (311) of the water-saving tank (300) which is connected to a hole (210) of the water storage tank (200).

[0115] Here, an opening (430) is formed on the lower outer circumference of the cylindrical body (410) so that the inside and outside are connected, and a cylindrical support (440) having a central portion penetrated is formed below the center of the opening (430), and the outlet at the bottom of the support (440) is fixed to be aligned with the hole (311) of the water-saving tank (300), and the upper inlet of the support (440) is opened and closed in a state where it is kept airtight by an opening (420) that rises and falls inside the cylindrical body (410), and an overflow (450) that is bent upward and extended to a predetermined length is installed on the side of the support (440), so that water flowing in through this overflow (450) always flows out through the outlet of the support (440) regardless of whether the support (440) is opened or closed, thereby ensuring the water quality of the water tank (200). Prevents overflow.

[0116] The air movement member (500) is

[0117] The trap part (120) and the water-saving tank (300) of the toilet body (100) described above are connected to each other, and when the water contained in the water-saving tank (300) moves to the bowl part (110), the air in the trap part (120) is introduced into the water-saving tank (300), thereby promoting the pressurization of the water moving from the water-saving tank (300) to the bowl part (110).

[0118] The air moving member (500) may be configured to include, as a preferred embodiment, a first moving pipe (510) whose upper end is connected to the connecting portion (321) of the water saving tank (300), a second moving pipe (520) whose lower end is connected to the straight section (122) of the trap section (120), and a connecting member (530) which is installed through the bottom surface of the water storage tank (200) so as to maintain an airtight seal, and which is located inside the water storage tank (200) and is connected to the lower end of the first moving pipe (510), and the other end is located outside the water storage tank (200) and is connected to the upper end of the second moving pipe (520) to connect the first moving pipe (510) and the second moving pipe (520) to each other.

[0119] Here, the connecting member (530) is a cylindrical body as shown in FIGS. 6 and 7, with a screw thread at the bottom, that penetrates from the inside to the outside of the bottom surface of the water tank (200) together with a sealing ring, and a nut is fastened to the screw thread of the body that penetrates the outside of the bottom surface of the water tank (200), so that the connecting member (530) can be fixed in a state of penetrating the water tank (200).

[0120] And the upper end of the first moving pipe (510) can be detachably connected to the connecting portion (321) of the water-saving tank (300) through the connecting portion (511), and the connecting portion (511) is formed with a first vertical portion (513) connected to the first moving pipe (510) on one side of the horizontal portion (512) as shown in FIG. 6, and a second vertical portion (514) connected to the connecting portion (321) on the other side of the horizontal portion (512), and a ventilation hole (517) is formed at the longitudinal end of the horizontal portion (512), so that the air moving through the first moving pipe (510) in the trap portion (120) moves to the second storage portion (320) through the first vertical portion (513), the horizontal portion (512), the second vertical portion (514), and the connecting portion (321). The ventilation hole (517) of the horizontal section (512) prevents the straight section (122) from becoming vacuum and stopping the air flow.

[0121] The connecting port (511) is formed in the form of a vent (515) at the longitudinal end of the horizontal portion (512), and the vent (515) is configured to be opened and closed through a plug (516) having a vent hole (517), so that when it is necessary to quickly release a vacuum formed in a straight section (122) of the trap portion (120), or when the inside of the horizontal portion (512) or the vent hole (517) is blocked, or when the inside of the horizontal portion (512) needs to be inspected, the plug (516) of the vent hole (515) can be opened to effectively deal with the situation.

[0122] Meanwhile, the lower end of the second moving pipe (520) can be detachably connected to the fitting hole (124) formed in the straight section (122) of the trap section (120) through the coupling member (521). As a preferred embodiment, the coupling member (521) is configured such that one end is connected to the lower end of the second moving pipe (520), and the other end is an elastic clip member (522), so that the coupling member can be elastically fitted and fixed to the fitting hole (124) of the straight section (122), and when the elastic clip member (522) is to be separated from the fitting hole (124), the outer side of the elastic clip member (522) is pressed inward, so that the elastic clip member (522) can be simply separated from the fitting hole (124).

[0123] In addition, the outside of the elastic clip part (522) can be configured to be wrapped with a sealing member (523) made of a material such as silicone, and a fitting groove (125) is formed on the outer circumference of the fitting hole (124) of the straight section (122), so that when the elastic clip part (522) is fitted into the fitting hole (124) and fixed, the end of the sealing member (523) is fitted into the fitting groove (125), so that the sealing between the fitting hole (124) and the elastic clip part (522) can be firmly maintained through the sealing member (523).

[0124] Here, by installing a sealing projection or sealing ring on the outer circumference of the end of the sealing member (523), the sealing of the fitting hole (124) and the elastic clip part (522) can be further strengthened.

[0125] Meanwhile, when the fitting hole (124) connected to the coupling hole (521) of the second moving pipe (520) is formed in the straight section (122) of the trap section (120), it is preferable to form it on the upper side of the straight section (122) in the trap section (120) so that the air in the straight section (122) can be quickly and effectively moved to the second storage section (320) of the water-saving tank (300) through the air moving member (500), and it may be formed on the front as well as the side on the upper side.

[0126] Meanwhile, the air movement member (500) according to an embodiment of the present invention is composed of a first movement pipe (510), a second movement pipe (520), and a connecting member (530) as described above for convenience of manufacturing, assembly, replacement, and maintenance, but this air movement member (500) may also be composed of a single integrated pipe.

[0127] In addition, according to an embodiment of the present invention, the first moving pipe (510) and the second moving pipe (520) constituting the air moving member (500) may be any one of a metal pipe, a reinforced glass pipe, a ceramic pipe, or a rubber pipe manufactured to have a constant inner diameter so as to provide efficiency and accuracy of air movement, and may be manufactured as a synthetic resin pipe made of transparent, opaque, or semitransparent material that is easy to manufacture and convenient for installation, replacement, and inspection.

[0128] In addition, the first moving pipe (510) and the second moving pipe (520) may have vortex-shaped air induction grooves formed along the length direction to improve the flow of air on the inner surface of the first moving pipe (510) and the second moving pipe (520) as another embodiment.

[0129] In addition, when air moves from the straight section (122) of the trap section (120) to the second moving pipe (520), some of the waste passing through the straight section (122) may flow into the second moving pipe (520), so a filter or check valve may be installed in one part of the second moving pipe (520).

[0130]

[0131] The process of using an ultra-saving toilet in which a trap according to the present invention is assembled is as follows.

[0132] First, before using the toilet, as shown in Fig. 8, the hole (311) of the water-saving tank (300) is closed by the opening (420) of the water discharge device (400), the water level of the water storage tank (200) is full, and the first storage section (310) and the second storage section (320) of the water-saving tank (300) are also full except for the upper free space.

[0133] In this state, when the user sits on the seat on the upper part of the bowl (110) and uses the toilet, and then operates the lever located on the outside of the water tank (200) to dispose of the waste temporarily stored in the bowl (110), as shown in FIG. 9, the opening (420) of the water discharge device (400) located in the first storage part (310) of the water-saving tank (300) is raised and spaced apart from the upper inlet of the support part (440), and the water in the first storage part (310) is discharged through the opening (430) of the water discharge device (400) and moves to the bowl part (110) of the toilet body (100) through the hole (311) of the water-saving tank (300) and the perforation (210) of the water storage tank (200).

[0134] At this time, the water in the second storage unit (320) also flows out through the lower communication port (331) of the bulkhead (330) and flows out to the bowl unit (110) through the opening (430), the hole (311) and the perforation (210). In this process, as the volume into which air can flow in the upper part of the second storage unit (320) expands, the pressure decreases. Due to this decompression action, the air located in the straight section (122) of the trap unit (120) is instantly sucked in through the air moving member (500) and moves to the second storage unit (320), thereby promoting and pressurizing the movement of the water flowing out from the second storage unit (320) through the hole (311). Due to this action, the waste in the bowl unit (110) effectively passes through the inclined section (121) of the trap unit (120). After passing through the straight section (122) and the trap section (123) once again, it is discharged into the sewage pipe by the action of the siphon.

[0135] Accordingly, it is possible to effectively discharge waste temporarily stored in the bowl (110) using a small amount of water stored in the first storage section (310) and the second storage section (320) of the water-saving tank (300), and the amount of water used at this time can be a maximum of 3.8 liters and a minimum of 2.7 liters, and on average, can be approximately 3.5 liters.

[0136] Meanwhile, when the opening (420) of the water discharge device (400) is opened to treat waste in the bowl (110), and the water stored in the water-saving tank (300) flows out through the opening (430) of the water discharge device (400) to the bowl (110) through the hole (311) of the water-saving tank (300) and the perforation (210) of the water storage tank, only a small amount of the water in the water storage tank (200) flows into the water-saving tank (300) through the inlet (340) of the water-saving tank (300), so the water level of the water storage tank (200) does not change significantly, as shown in FIG. 9.

[0137] Accordingly, when the opening (420) of the water discharge device (400) is closed as shown in FIG. 10, the water remaining in the water storage tank (200) flows into the water-saving tank (300) through the inlet (340), so that the first storage section (310) and the second storage section (320) of the water-saving tank (300) are quickly filled, and the water level of the water storage tank (200), which is relatively decreasing, can be replenished through the operation of the water level control device provided in the water inlet pipe.

[0138] In the case of conventional toilets, since all the water stored in a large water tank is used up, not only is the amount of water consumed large, but it also takes a long time to refill the water tank, which inevitably lengthens the interval at which water can be discharged back into the bowl. However, in the ultra-water-saving toilet of the present invention, after the water in the water-saving tank (300) with a relatively small storage capacity is used to treat waste, the water is quickly filled into the water-saving tank (300), so the interval at which water can be discharged back into the bowl (110) can be shortened, which can double the convenience for the user.

[0139] Meanwhile, FIGS. 15 to 18 illustrate other embodiments of a water-saving tank (300a) and a water discharge device (400a) according to the present invention. First, as illustrated in FIGS. 15 to 17, the water-saving tank (300a) has a first storage unit (310a) formed in the center, in which a portion of the upper surface is open and a hole (311a) is formed on the inner bottom surface so as to be connected to the through hole (210) of the water tank (200), and a second storage unit (320a) is formed around the outer periphery of the first storage unit (310a) and is partitioned by a partition wall (330a), and the first storage unit (310a) and the second storage unit (320a) can be configured to communicate with each other so that water can move between them through the lower end of the partition wall (330a).

[0140] And, a plurality of inlets (340a) can be formed on the bottom surface of the water saving tank (300a) so that water from the water storage tank (200) can be filled into the first storage portion (310a) and the second storage portion (320a) of the water saving tank (300a).

[0141] In addition, the water-saving tank (300a) may be configured as a single body, and for convenience of manufacturing and ease of maintenance, it may be configured in a form in which the upper and lower parts are divided and assembled together, as shown in FIG. 15.

[0142] In addition, as shown in FIG. 16, a connecting portion (321a) may be formed protrudingly on the upper side of the water-saving tank (300a) so as to be connected to the second storage portion (320a), and this connecting portion (321a) is connected to the air movement member (500) described above, so that the air moved through the air movement member (500) is accurately and quickly moved vertically downward from the upper side of the second storage portion (320a), thereby effectively promoting pressurization of the water in the second storage portion (320a) by the moved air.

[0143] And, when connected to the hole (210) of the water tank (200), a rubber packing may be installed together with the hole (311a) of the water tank (300a) to maintain airtightness.

[0144] And the water discharge device (400a) is installed inside the water-saving tank (300a) as illustrated in FIGS. 17 and 18, and by operating the lever to open and close the hole (311a) of the water-saving tank (300a), the water stored in the water-saving tank (300a) can be controlled to move to the bowl part (110).

[0145] Specifically, the water discharge device (400a) may be composed of an overflow (450a) installed in the first storage portion (310a) of the water-saving tank (300a) and an opening (420a) rotatably installed in the overflow (450a). A fitting portion (451a) having a drain hole (452a) is formed at the bottom of the overflow (450a), and the fitting portion (451a) is fitted into the hole (311a) of the water-saving tank (300a). At this time, a screw line is formed on the outer surface of the fitting portion (451a), so that the fitting portion (451a) is inserted into the hole (210) of the water storage tank (200), and a nut is fastened to the fitting portion (451a) from the inside of the bowl portion (110), thereby fixing the overflow (450a).

[0146] And the opening (420a) is connected to a lever installed on the outside of the water tank (200) through a wire at the top, so that when the opening (420a) is rotated and lifted according to the operation of the lever, the lower part of the opening (420a) is separated from the drain hole (452a) of the fitting (451a), and the hole (311a) of the water-saving tank (300a) is opened through the drain hole (452a), so that the water in the water-saving tank (300a) can move to the bowl part (110).

[0147] Here, the lower part of the opening (420a) is hemispherical and made of a material that has elasticity like rubber, so that the lower part of the opening (420a) can close the drain hole (452a) of the fitting (451a) in a state where it is kept airtight.

[0148] While the detailed description of the present invention has described specific embodiments, it should be understood that various modifications are possible without departing from the scope of the disclosed subject matter. Therefore, the scope of the disclosed subject matter should not be limited to the described embodiments, but should be determined not only by the claims set forth below but also by equivalents thereof.
