Description

Toilet with odor removal

[0001] The present invention relates to a toilet, and more specifically, to a toilet capable of removing odors that can effectively remove odors generated by excrement.

[0002] The foul odor produced during defecation not only causes discomfort to the person defecating, but also to all users entering and exiting the restroom, and is one of the major factors that deteriorates the indoor environment of the restroom.

[0003] To solve this problem, air fresheners and air purifiers are placed around the toilet and inside the bathroom. However, this does not eliminate the odor in the bathroom at its source. Rather, it offsets the odor in the bathroom with the fragrance emitted by the air freshener or air purifier, preventing the user from feeling the odor. Therefore, it cannot be considered a fundamental solution to eliminating odor in the bathroom.

[0004] And, in some cases, there was a problem where the fragrance of the air freshener and the bad smell of the bathroom mixed together to create an even more strange smell, which had the counterproductive effect of amplifying the user's discomfort.

[0005] Additionally, most restrooms have ventilators installed on one wall to ventilate the indoor air, but this is only to ventilate the entire indoor air of the restroom, and cannot immediately expel the foul odor generated when the user uses the toilet to the outside. Therefore, there was a problem in that the ventilation function occurred only after the foul odor generated when using the toilet had spread inside the restroom.

[0006] The purpose of the present invention is to solve the above-described problem, and to provide an odor-eliminating toilet that can immediately remove the odor generated during defecation.

[0007] Another object of the present invention is to provide an odor-eliminating toilet that can prevent the odor generated during defecation from spreading to the surroundings.

[0008] The above objects and various advantages of the present invention will become more apparent to those skilled in the art from the preferred embodiments of the present invention.

[0033] To fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same parts are sometimes depicted with the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the present invention are omitted.

[0034] Fig. 1 is a perspective view showing the configuration of a odor-removing toilet (100) according to the present invention, and Fig. 2 is a cross-sectional view showing the cross-sectional configuration of the odor-removing toilet (100).

[0035] As illustrated, the odor-removing toilet (100) according to the present invention includes a toilet body (110), a seat (120) rotatably coupled to the upper portion of the toilet body (110), a toilet cover (130) rotatably coupled to the upper portion of the toilet seat (120) to cover the seat (120), and an odor-removing unit (140) coupled to the toilet seat (120) to allow odor to be sucked in through the toilet seat (120), remove the sucked odor with a filter (144, 146), and then discharge the treated air through the toilet seat (120).

[0036] The odor removing toilet (100) according to the present invention absorbs odor generated from excrement through the toilet seat (120), the odor removing unit (140) removes the absorbed odor using a filter (144, 146), and discharges treated air (A) from which odor components have been removed from the upper portion of the toilet seat (120) to the toilet body (110).

[0037] As shown in Fig. 2, the treated air (A) is discharged to the upper part of the toilet body (110) and forms an air curtain by covering the upper part of the toilet body (110), thereby blocking the odor (M) generated from the lower part from spreading to the outside. This has the effect of preventing the odor generated from the excrement from spreading to the outside of the toilet and being immediately treated through the toilet cover (130) and the odor removal unit (140).

[0038] The toilet body (110) receives waste such as urine and feces and uses water to flush the waste into a septic tank. The structure of the toilet body (110) is the same as the known structure, so a detailed description is omitted.

[0039] The seat (120) is rotatably connected to the toilet body (110) and allows a woman to sit and relieve herself or a man to sit and relieve himself. As shown in FIG. 2, the toilet seat (120) includes a seat body (121) having an empty interior, a partition wall (123) that is horizontally connected to the interior of the seat body (121) and divides the seat body (121) into an air discharge space (122) and an odor inflow space (124), a plurality of air discharge holes (125) formed along the circumferential direction of the inner wall surface of the seat body (121) so as to be in communication with the air discharge space (122), and a plurality of odor inflow holes (127) provided at regular intervals on the inner wall surface of the seat body (121) so as to be in communication with the odor inflow space (124).

[0040] The toilet seat (120) not only has the function of allowing a man or woman to sit and relieve themselves, but also functions as a passage for odor (M) and air (A) to flow in and out when combined with a odor removal unit (140). The seat body (121) is divided vertically into an air discharge space (122) and an odor inflow space (124) by a separation partition (123). As illustrated in Fig. 2, the odor inflow space (124) is connected to an odor inflow pipe (141) of the odor removal unit (140), and the air discharge space (122) is connected to an air movement pipe (148) of the odor removal unit (140).

[0041] A plurality of air exhaust holes (125) are formed at regular intervals along the circumferential direction on the inner wall surface of the seat body (121) where the separation partition (123) and the seat body (121) are in contact. The air exhaust holes (125) are formed to be inclined downward at regular intervals, so that, as shown in Fig. 2, air (A) discharged from the air exhaust holes (125) is discharged horizontally and at a regular angle to the upper portion of the toilet body (110), thereby forming an air curtain of a certain thickness on the upper portion of the toilet body (110).

[0042] The air curtain forms an air layer on the upper part of the toilet body (110) to prevent the foul odor generated from the toilet inside from spreading to the outside through the open upper part of the toilet body (110).

[0043] Meanwhile, the odor inlet hole (127) is formed along the inner wall surface of the sheet body (121) below the air discharge hole (125). The odor inlet hole (127) is provided to be spaced apart from the air discharge hole (125) in the upper and lower directions to prevent the odor (M) and air (A) from mixing.

[0044] The odor removal unit (140) is connected to the toilet seat (120) and operates so that odor is introduced through the odor inlet hole (127) and treated air (A) with odor components removed is discharged through the air discharge hole (125). The odor removal unit (140) includes an odor inlet pipe (141) that is connected to the odor inlet space (124) of the toilet seat (120) and sucks in odor (M), a filter casing (143) that is connected to the odor inlet pipe (141) and houses a filter (144, 146) that removes odor components of the odor (M) that has moved through the odor inlet pipe (141), an air movement pipe (148) that is connected to the filter casing (143) in the opposite direction to the odor inlet pipe (141) and discharges treated air (A) from which odor components have been removed to the air discharge space (122), and an odor suction fan (147) that is provided between the filter casing (143) and the air movement pipe (148) and applies pressure so that odor is sucked in and air is discharged.

[0045] The filter casing (143) is provided as a cylindrical tube and houses a filter (144, 146) and an odor suction fan (147) inside. One end of the filter casing (143) is connected to an odor inlet pipe (141), and the other end is connected to an air movement pipe (148).

[0046] A path change plate (145) is provided in the central area of ​​the filter casing (143) to divide it into a lower filter (144) and an upper filter (146), and to change the movement path of the odor (M) to improve the odor component removal efficiency.

[0047] The lower filter (144) and the upper filter (146) are provided in the form of hollow tubes with an empty interior. The lower filter (144) is fixedly connected to the lower portion of the filter casing (143) by a lower filter fixing ring (144a). The lower filter fixing ring (144a) is connected to the odor inlet pipe (141).

[0048] As shown in Fig. 4, the odor (M) introduced into the odor inlet pipe (141) is introduced into the lower filter (144) through the lower filter fixing ring (144a), moves along the space between the filter casing (143) and the lower filter (144) through the surface of the lower filter (144), and is introduced into the upper filter (146).

[0049] The odor (M) that has moved from the surface of the upper filter (146) to the inside of the upper filter (146) moves along the upper filter (146) and the odor component is removed. An upper filter coupling ring (146a) is provided at the top of the upper filter (146) and is coupled to the inner wall surface of the filter casing (143).

[0050] By the path change plate (145), the odor (M) moves from the inside of the lower filter (144) to the outside of the lower filter (144), then moves from the outside of the upper filter (146) to the inside of the upper filter (146), and then follows a path to the air movement pipe (148). As the path of the odor (M) is lengthened by the path change plate (145), the time of contact with the lower filter (144) and the upper filter (146) is lengthened, so the removal efficiency of the odor component can be improved.

[0051] The odor suction fan (147) is provided inside the filter casing (143) between the upper filter (146) and the air movement pipe (148). The odor removal unit (140) of the present invention performs two functions: suction of odor (M) and discharge of air (A) using one odor suction fan (147).

[0052] As the odor suction fan (147) provided on the upper filter (146) rotates, the generated suction pressure causes the odor (M) to flow into the odor inlet hole (127) of the toilet seat (120), and the treated air (A) purified of the odor components by contacting the filters (144, 146) moves along the air movement pipe (148) by the discharge pressure of the odor suction fan (147) and is then discharged through the air discharge hole (125) to form an air curtain.

[0053] The operation process of the odor-removing toilet (100) according to the present invention having such a configuration is described with reference to FIGS. 1 to 4.

[0054] As illustrated in Fig. 1, a toilet seat (120) is rotatably connected to the upper portion of a toilet body (110), and an odor removal unit (140) is connected to the toilet seat (120). At this time, the odor suction fan (147) of the odor removal unit (140) is connected so that constant power is supplied.

[0055] When a user enters a restroom and defecates in the toilet body (110), an unpleasant odor (M) is generated. At this time, as illustrated in Fig. 2, the unpleasant odor (M) generated from the defecation is sucked in through the unpleasant odor intake hole (127) of the toilet seat (120) and moves to the unpleasant odor intake pipe (141) via the unpleasant odor intake space (124).

[0056] As shown in FIGS. 3 and 4, the odor (M) is introduced into the odor inlet pipe (141), and then passes through the lower filter (144) and the upper filter (146) to remove the odor components. The treated air (A) from which the odor components have been removed moves along the air movement pipe (148), then moves to the air discharge space (122) of the toilet seat (120), and is discharged to the toilet body (110) through the air discharge hole (125).

[0057] At this time, air (A) discharged from a plurality of air exhaust holes (125) formed at regular intervals along the inner wall surface of the toilet seat (120) covers the upper surface of the toilet body (110) and forms an air curtain. This prevents the foul odor (M) generated inside the toilet body (110) from spreading to the outside.

[0058] Since the odor suction fan (147) operates continuously, an air curtain is continuously maintained on the upper part of the toilet body (110), so that the odor (M) generated from the feces of the toilet body (110) can be prevented from spreading inside or outside the toilet.

[0059] Meanwhile, Fig. 5 is a perspective view illustrating the configuration of a odor-eliminating toilet (100a) according to another embodiment of the present invention. The odor-eliminating toilet (100) according to the preferred embodiment of the present invention described above has an odor-eliminating unit (140) provided on the outside of the toilet seat (120) and connected to the toilet seat (120) by an odor inlet pipe (141) and an air movement pipe (148).

[0060] The odor-eliminating toilet (100) according to this preferred embodiment had inconveniences when rotating the toilet seat (120) to the upper part of the toilet body (110) due to the shape and weight of the odor-eliminating part (140).

[0061] Accordingly, the odor removal toilet (100a) according to another embodiment illustrated in FIG. 5 has the advantage of accommodating the odor removal part (140) inside the toilet seat (120) to facilitate the up-and-down rotation of the toilet seat (120).

[0062] FIG. 6 is a cross-sectional view showing the cross-sectional configuration of a toilet seat (120) of a odor-eliminating toilet (100a) according to another embodiment, and FIGS. 7 and 8 are side cross-sectional views showing the process in which the toilet seat (120) and toilet cover (130) of the odor-eliminating toilet (100a) rotate up and down.

[0063] As shown in FIGS. 6 and 7, the toilet seat (120) is rotatably connected to the toilet body (110) in a vertical direction. At this time, a filter receiving space (128) is formed in the connecting area that is rotatably connected to the toilet body (110) in a vertical direction, and an odor removal unit (140) is received in the filter receiving space (128). The odor removal unit (140) provided in the filter receiving space (128) is connected to an odor inflow space (124) at the bottom of the separation partition (123) by an odor inflow pipe (141), as shown in FIG. 7, and an air guide pipe (126) is provided in the air discharge space (122) at the top of the separation partition (123) to be connected to an air movement pipe (148). Here, the configuration and operation process of the odor removal unit (140) are the same as those of the odor removal toilet (100) of the preferred embodiment described above.

[0064] The odor-removing toilet (100) according to the preferred embodiment described above is provided with an air discharge hole (125) on the inside of the air discharge space (122) as shown in FIG. 2, so that the treated air (A) from which odor components have been removed from the odor-removing unit (140) is discharged to the toilet body (110).

[0065] On the other hand, a odor-removing toilet (100a) according to another embodiment is provided with an air guide pipe (126) inside an air discharge space (122), as illustrated in FIG. 6, and the air guide pipe (126) is arranged to be in communication with an air discharge hole (125). That is, the air discharge hole (125) is formed on the inside of the air discharge space (122), and an internal air discharge hole (not illustrated) is formed in the air guide pipe (126) in communication with the air discharge hole (125).

[0066] The air guide pipe (126) guides the treated air (A) discharged to the air movement pipe (148) by the odor suction fan (147) of the odor removal unit (140) to be discharged to the air discharge hole (125) at the same pressure. To this end, the air guide pipe (126) is formed so that its width gradually narrows from the area connected to the air movement pipe (148) in the direction away from the air movement pipe (148) (W1>W2).

[0067] Since the width of the air guide tube (126) gradually narrows from the rear to the front, the speed of the treated air (A) discharged through the air movement tube (148) can be maintained constant throughout the entire area of ​​the air guide tube (126). Accordingly, the pressure of the air curtain formed by the treated air (A) discharged to the toilet body (110) through the air discharge hole (125) can also be maintained uniformly throughout the entire area, so that odors generated from the toilet body (110) can be uniformly blocked from being discharged to the outside throughout the entire area.

[0068] Fig. 9 is a perspective view showing the configuration of a odor-eliminating toilet (100b) according to another embodiment of the present invention, and Fig. 10 is a cross-sectional view showing the flat cross-section configuration of the odor-eliminating toilet (100b). The toilet cover (130) and the toilet seat (120) are rotatably connected to the toilet body (110) by a rotation shaft (131).

[0069] According to another embodiment, a odor removing toilet (100b) has a odor removing unit (140) housed inside a cover connecting tube (129) of a toilet seat (120). A pair of shaft connecting legs (132) are arranged coaxially on both sides of the cover connecting tube (129), and a rotation shaft (131) is inserted through the shaft connecting legs (132) and the cover connecting tube (129).

[0070] An odor removal unit (140) is accommodated inside the cover coupling tube (129), and the odor removal unit (140) is connected to the odor inflow space (124) by the odor inflow tube (141) and to the air discharge space (122) by the air movement tube (148).

[0071] At this time, the air exhaust hole (125a) formed in the sheet body (121) may be provided in the form of a long hole having a certain length. Compared to a circular air exhaust hole (125), the long air exhaust hole (125a) has the advantage of being able to form a more uniform air curtain.

[0072] Meanwhile, (a) and (b) of FIG. 11 are exemplary diagrams illustrating the process of rotating the toilet seat (120) of the odor-eliminating toilet (100b). Here, the odor inlet pipe (141) is connected to the odor inlet space (124), and the variable air movement pipe (149) is connected to the air discharge space (122). At this time, the variable air movement pipe (149) connected to the air discharge space (122) may be provided in a form in which the length is adjustable.

[0073] That is, the variable air movement pipe (149) is provided in the form of a corrugated pipe, and as shown in (a) of FIG. 11, when the toilet seat (120) is closed with respect to the toilet body (110), it is maintained in a folded state, and as shown in (b) of FIG. 11, when the toilet seat (120) is rotated vertically with respect to the toilet body (110) and opened, the corrugations of the variable air movement pipe (149) are spread out and extended outward to become longer.

[0074] Meanwhile, the variable air movement pipe (149) may be inserted into the air discharge space (122) in the form of a corrugated pipe or a curved pipe, or may be exposed to the outside, and may be provided in the form of a multi-stage antenna with a variable length.

[0075] Meanwhile, Fig. 12 is a perspective view showing the configuration of a odor-removing toilet (100c) of another embodiment.

[0076] In the odor-removing toilet (100, 100a) of the preferred embodiment described above and another embodiment, the air exhaust hole (125) is formed over the entire area along the inner wall surface of the seat body (121) of the toilet seat (120).

[0077] On the other hand, as shown in Fig. 12, in another embodiment of the odor-removing toilet (100c), the air exhaust hole (125a) is formed only in an area corresponding to half of the seat body (121).

[0078] If air exhaust holes (125) are formed in the entire area of ​​the seat body (121), there is a risk that a vortex may be formed in the central area of ​​the seat body (121), causing an unpleasant odor to be emitted to the outside. To prevent this problem, in another embodiment, air exhaust holes (125a) are formed in only half the area.

[0079] In some cases, the air exhaust holes (125a) may be formed in sections within a range where no vortex is generated. That is, as shown, they may be formed only in an area corresponding to half of the entire toilet seat (120), or formed in three sections at 60-degree intervals, or formed in an opposing direction at 90-degree intervals.

[0080] Meanwhile, Fig. 13 is a cross-sectional view illustrating a modified example of the odor removal unit (140a). The odor removal unit (140) of the preferred embodiment illustrated in Fig. 4 is divided into an upper filter (144) and a lower filter (144) by a path change plate (145), and the odor (M) introduced through the odor inlet pipe (141) is moved from the inside of the lower filter (144) to the outside, then introduced again into the upper filter (144), and then moved along a path to the odor suction fan (147).

[0081] On the other hand, the odor removal unit (140a) according to the modified example is provided with a filter (144) that is not separated but is formed as one, and the lower part of the filter (144) is connected to the lower part (143a) of the filter casing (143). In addition, the odor inlet pipe (141) is extended and inserted into the interior of the filter (144).

[0082] The upper part of the filter (144) is closed by the upper filter cap (144d) and separated from the odor suction fan (147). As a result, the odor (M) moved to the odor inlet pipe (141) is discharged into the filter (144) and then moves along the surface of the filter (144) to remove the odor component, and the air (A) moves along the space between the filter (144) and the filter casing (143) and then moves to the air movement pipe (148) through the odor suction fan (147).

[0083] Meanwhile, Fig. 14 is a cross-sectional view showing the cross-sectional configuration of an odor removal unit (140b) according to another modified example.

[0084] Another modified example of an odor removal unit (140b) also has a single filter (144) structure, and the lower part of the filter (144) is blocked by a lower filter cap (144c) and the upper part extends to an odor suction fan (147).

[0085] The odor (M) introduced through the odor inlet pipe (141) connected to the filter casing (143) is introduced into the filter casing (143) and then into the filter (144) from the side, moves along the filter (144), and after the odor component is removed, moves directly to the air movement pipe (148) along the odor suction fan (147).

[0086] Meanwhile, Fig. 15 is a cross-sectional example showing the configuration of another modified example of an odor removal unit (140c).

[0087] The odor removal unit (140, 140a, 140b) described above purifies the odor using one odor suction fan (147) and then discharges the air.

[0088] On the other hand, another modified example of an odor removal unit (140c) is equipped with an odor suction fan (147) that sucks in odor and an air exhaust fan (147-1) that discharges air (A), thereby separating suction and discharge.

[0089] An odor suction fan (147) is provided in an intake fan casing (147a) on the filter (144) side connected to the odor inlet pipe (141) of the cover coupling pipe (129), and an air exhaust fan (147-1) is provided in an exhaust fan casing (147-1a) provided at a certain distance from the odor suction fan (147), and the air exhaust fan (147-1) is connected to an air movement pipe (148). Accordingly, air (A) from which odor components have been removed through the filter (144) is discharged to the odor suction fan (147) and then discharged to the air movement pipe (148) through the air exhaust fan (147-1).

[0090] Meanwhile, Fig. 16 is a drawing showing the configuration of another odor removal unit (140d). As shown, another odor removal unit (140d) is connected to an odor suction fan (147) by overlapping an upper filter (144) and a lower filter (144) that are provided in a thin, thin shape inside a filter casing (143).

[0091] When the upper filter (144) and the lower filter (144) are arranged in a thin, overlapping manner and connected to the odor suction fan (147), there is an advantage in that the space efficiency of the filter receiving space (128) including the filter casing (143) can be increased.

[0092] As seen above, the odor removing toilet according to the present invention has an odor suction fan that operates continuously to suck up odor, so that odor generated by defecation can be immediately removed.

[0093] In addition, the treated air from which the odor components have been removed in the odor removal unit is discharged into the toilet body along the inner wall of the seat body, forming an air curtain to prevent the odor generated by excrement from spreading to the outside. This effectively prevents the generation of odor.

[0094] The embodiments of the odor-eliminating toilet of the present invention described above are merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent other embodiments are possible. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the detailed description above. Accordingly, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.
