Description

TECHNICAL FIELD

[0001] The present disclosure relates to technical field of sanitary ware, and in particular to a bidet with an integrated built-in water tank.

BACKGROUND

[0002] Bidets, serving as toilets, are conventionally arranged with built-in water tanks that can be divided into two kinds, one is that the water tank and the seat are separated with the water tank being placed in the wall, the other is that the water tank and the seat are installed in an integrated (one-piece) manner. The split-type tanks are not as popular as integrated-type tanks because they are not easy to install. The internal structure of the seat is complex, such as the lower surface of the bidet main body, and the curved sewage pipe, and the seat is usually a ceramic structure. Therefore, it is necessary to provide multiple process holes on the shell of the seat in order to facilitate the manufacture of the seat, for example, the process holes are provided between a bottom wall of the shell and a front sidewall of the shell. As a result, water cannot be stored between the shell and the bidet main body.

[0003] In order to facilitate manufacturing and installation, the existing bidet with an integrated built-in water tank is generally designed that a water tank is arranged at a top of a rear end of the seat, or a plastic water tank is arranged in an inner cavity of the rear end of the seat. Further, since a sufficient height difference is required, it is necessary to adopt a water inlet valve and a water pump or pressurize the air in the integrated water tank. However, these technical solutions have problems that the water storage is in a small amount and water supply through the inlet valve is too slow due to low water pressure in the water consumption peak period, which may lead to cases that the bidet cannot be flushed even in one time. In addition, for the designs where the water tank is arranged on the top, the installation space of the intelligent toilet cover will be occupied, and the manufacturing difficulty of the seat is improved; for the designs of the plastic water tanks, problems also exist of resonant noise from the plastic tank and smart toilet cover when the pump starts the water, as well as of water leakage due to deterioration after a longer period of use.

[0046] The shell 14a, 14b is arranged at a periphery of the bidet main body 11; the shell 14a, 14b includes a front sidewall 15, a bottom wall 16, a left sidewall 17, a right sidewall 18, and a rear sidewall 19, 24; a bottom opening 29 is defined between the front sidewall 15 and the bottom wall 16 facing a front portion of the bedpan 12.

[0047] The partition 30 extends upwardly from the bottom wall 16; the partition 30, the bottom wall 16, the left sidewall 17, the right sidewall 18, and the rear sidewall 19, 24 enclose to form a water tank 31 that is opened upwardly; the partition 30, the shell 14a, 14b, and the bedpan 12 are of an integrated ceramic structure.

[0048] The water inlet assembly 40a, 40b and the jetting assembly 50 are disposed in the water tank 31; the water inlet assembly 40a, 40b includes a water inlet pipe 41 and a water valve assembly 42 connected in series to the water inlet pipe 41; the jetting assembly 50 includes a jetting pipe 51 and a water pump 52 connected in series to the jetting pipe 51, and the jetting pipe 51 is connected to the bedpan 12.

[0049] In the embodiments, the seat 10a, 10b is a main structure; the water inlet assembly 40a, 40b and the jetting assembly 50 are disposed on the seat 10a, 10b; the bidet main body 11 and the shell 14a, 14b of the seat 10a, 10b may be adopted from the related art; the bedpan 12 is configured to receive excrement, and the jetting assembly 50 is configured to jet water into an inner cavity of the bidet main body 11, so as to discharge the excrement into a pipe connected to a septic tank through the drain pipe 13. The drain pipe 13 is usually arranged with a water reservoir for odor prevention, and the drain pipe 13 may be further arranged with an upwardly-arched curved portion to prevent backflow. The shell 14a, 14b is not only a cosmetic part, but also provides support for the bidet main body 11. The seat 10a, 10b may be installed either on a bottom surface or on a vertical surface, such as on a wall or on a stand having a vertical installation surface. The water inlet assembly 40a, 40b and the jetting assembly 50 may be adopted from the related art; the water valve assembly 42 may be either a manual valve or an electromechanical automatic valve, such as a solenoid valve, or a purely mechanical automatic valve.

[0050] As proposed by the present disclosure, the bidet 100, 200 with an integrated built-in water tank is arranged with an integrated ceramic structure of the partition 30, the shell 14a, 14b, and the bedpan 12. In this way, while retaining the bottom opening 29, the upwardly-opened water tank 31 is formed by enclosing the partition 30, the bottom wall 16, the left sidewall 17, the right sidewall 18, and the rear sidewall 19, 24, such that the space in a rear portion of the seat 10a, 10b is fully utilized, and the formed water tank 31 has a large capacity and can cooperate with the water pump 52 for a long and stable flushing operation. Moreover, since the bottom opening 29 is retained and the water tank 31 has an opening facing upward, an outer surface of the bidet main body 11 can be easily accessed from the outside, such that the setting of the water tank 31 does not affect the shaping of the bidet main body 11. The opening on an upper portion of the water tank 31 also facilitates the installation of a smart toilet cover, whereby a lower raised portion at a rear end of the smart toilet cover can be embedded in the water tank 31, thereby making the overall height of the product lower, which in turn enhances the installation adaptability or reduces the space occupation. Since the water tank 31 is constructed of ceramic material and is integrally structured with the bidet main body 11 and the rest of the shell 14a, 14b, it is less likely to resonate with vibration of the water pump 52, which can provide the user with a better silent experience.

[0051] Further, the rear sidewall 19, 24 defines a water inlet installation hole 20, 25, and the water inlet assembly 40a, 40b further includes a water inlet fitting 43; an outlet of the water inlet fitting 43 is connected to an inlet of the water inlet pipe 41; the water inlet fitting 43 is removably connected to the water inlet installation hole 20, 25.

[0052] In the embodiments, the water inlet fitting 43 can facilitate connection of the water inlet pipe 41 to the municipal water pipe and support the water inlet pipe 41.

[0053] Further, the rear sidewall 19, 24 includes a base 21, 26 and a bulge 22, 27 that bulges inwardly from the base 21, 26; the bulge 22, 27 defines a cavity 23, 28 that is opened toward an outside; the water inlet installation hole 20, 25 is defined on the bulge 22, 27 and is in communication with the cavity 23, 28; an outer end of the water inlet fitting 43 is disposed in the cavity 23, 28.

[0054] In the embodiments, installation of the seat 10a, 10b is facilitated by hiding the water inlet fitting 43 in the cavity 23, 28 of the bulge 22, 27 such that the base 21, 26 can be closer to or fit against the vertical installation surface.

[0055] Further, referring to FIGS. 1 to 7, in the first embodiment, in order to facilitate the connection of the water pipe at the bottom and to reduce the height of a main part of the water inlet assembly 40a for facilitating the installation of the toilet cover, the bulge 22 is connected to a lower portion of the base 21, and the bulge 22 includes a top plate 221 and an enclosure plate 222; the top plate 221 extends forwardly from an inner surface of the base 21, the enclosure plate 222 extends upwardly from the bottom wall 16, the enclosure plate 222 is connected to the top plate 221 and the base 21, and the enclosure plate 222, the top plate 221, the base 21, and the bottom wall 16 enclose to define the cavity 23; the water inlet installation hole 20 is defined on the top plate 221, and the water inlet pipe 41 and the water valve assembly 42 are disposed above the bulge 22. In the embodiments, the bulge 22 is connected to the lower portion of the base 21, defining the cavity 23 with the bottom wall 16, which can simplify the setup of the bulge 22 and is conducive to minimizing the height of the top plate 221, thereby enhancing the compactness of the bidet.

[0056] Further, referring to FIGS. 8 to 15, in the second embodiment, in order to facilitate the connection of the water pipe near the top of the seat 10b and to reduce the height of a main part of the water inlet assembly 40b for facilitating the installation of the toilet cover, the bulge 27 is connected to an upper portion of the base 26, the bulge 27 includes a top plate 271, an enclosure plate 272, and an installation plate 273; the top plate 271 extends forwardly from an inner surface of the base 26, the installation plate 273 extends downwardly from a front edge of the top plate 271, and the enclosure plate 272 is connected to the top plate 271 and the installation plate 273; the enclosure plate 272, the top plate 271, and the installation plate 273 enclose to define the cavity 28; the water inlet installation hole 25 is defined on the installation plate 273, and the water inlet pipe 41 and the water valve assembly 42 are disposed on a front side of the bulge 27.

[0057] Further, referring to FIGS. 6 and 7, or referring to FIGS. 12 to 15, in the first and second embodiments, the water inlet fitting 43 includes a fitting body 44, a sealing ring 45, and a fastener 46; the fitting body 44 includes a tube portion 441 and a limiting flange 442 disposed on an outer peripheral surface of an inner end of the tube portion 441, and the outer peripheral surface of the tube portion 441 defines an outer thread; the tube portion 441 passes through the water inlet installation hole 20, 25; the limiting flange 442 is disposed on an inner side of the rear sidewall 19, 24, the sealing ring 45 is disposed between the limiting flange 442 and the rear sidewall 19, 24, and the fastener 46 is threadedly mated with the tube portion 441 and disposed on an outer side of the rear sidewall 19, 24.

[0058] In the embodiments, the sealing ring 45 can be tightly pressed between the limiting flange 442 and the rear sidewall 19, 24 by screwing the fastener 46. In some embodiments, the sealing ring 45 has a tapered sealing surface, a small diameter of the sealing surface is set close to the rear sidewall 19, 24, and the small diameter of the sealing surface is less than an inner diameter of the inlet installation hole 20, 25.

[0059] Further, referring to FIGS. 1 to 6, or referring to FIGS. 8 to 12, in the first and second embodiments, the partition 30 extends upwardly to be connected to the bedpan 12, and an upper portion of the rear sidewall 19, 24 defines a window 211, 261 connected to the outside.

[0060] In the embodiments, the partition 30 extends upwardly to be connected to the bedpan 12, thereby increasing the capacity of the water tank 31, while the window 211, 261 defined on the rear sidewall 19, 24 can realize overflow and provide the possibility of touching the bidet main body 11 from another angle. It will be appreciated that in an event that the water valve assembly 42 malfunctions and the water tank 31 is overfilled, the overflow through the window 211, 261 prevents water from soaking electromechanical parts of the smart toilet cover located above.

[0061] Further, the drain pipe 13 has a curved portion extending into the water tank 31; the drain pipe 13 is arranged in the middle in a left-right direction; the water inlet assembly 40a, 40b and the water pump 52 are located on both sides of the drain pipe 13, respectively, in the left-right direction.

[0062] In the embodiments, the curved portion of the sewage pipe 13 extends into the water tank 31, meaning that the position of the partition 30 is sufficiently forward, such that it is conducive to expanding the capacity of the water tank 31. The water inlet assembly 40a, 40b and the water pump 52 are located on the both sides, which is conducive to ensuring that there is enough installation space for each other, thereby enhancing the installation efficiency.

[0063] Further, an inner wall surface of an upper portion of the bedpan 12 defines an annular flushing groove 121; the jetting assembly 50 further includes a three-way valve 53; the jetting pipe 51 includes a main path 511, and a first branch path 512 and a second branch path 513 respectively connected to two outlets of the three-way valve 53; the main path 511 is connected to an outlet of the water pump 52 and an inlet of the three-way valve 53; an outlet of the first branch path 512 is connected to a bottom of the bedpan 12, and an outlet of the second branch path 513 is connected to the flushing groove 121 on the upper portion of the bedpan 12.

[0064] In the embodiments, the jetting assembly 50 performs rinsing by two branch paths, such that a better rinsing effect can be achieved under the premise of the same amount of water; in other words, while achieving the same rinsing effect, the two branch paths may achieve a better water-saving performance.

[0065] Further, the partition 30 extends upwardly to be connected to the bedpan 12, and the partition 30 defines a through hole for the second branch path 513 to pass through.

[0066] In the embodiments, by defining the through hole on the partition 30, the second branch path 513 can be better connected to a portion of the drain pipe 13 at the foremost end, thereby enhancing the water flow in the direction from the front to the rear, and thus enhancing the rinsing effect.

[0067] In a third embodiment, referring to FIGS. 16 to 21 and FIG. 25, a bidet 300 with an integrated built-in water tank proposed in the present disclosure includes a seat 10c, a water inlet assembly 30c, and a jetting assembly 40c; the seat 10c includes a bidet main body 11c, a shell 14c, and a partition 20c.

[0068] The bidet main body 11c includes a bedpan 12c and a drain pipe 13c connected to the bedpan 12c.

[0069] The shell 14c is disposed at a periphery of the bidet main body 11c; the shell 14c includes a bottom wall 15c, a left sidewall 16c, a right sidewall 17c, and a rear sidewall 29c; the rear sidewall 29c includes a first rear sidewall 21c and a second rear sidewall 18c disposed facing each other in a front-rear direction, and the second rear sidewall 18c defines a hanging hole 181c and a drain through hole 182c.

[0070] The partition 20c and the first rear sidewall 21c are disposed opposite to each other in the front-rear direction and both extend upwardly from the bottom wall 15c, and a front portion of the bedpan 12c protrudes from a front side of the partition 20c; the partition 20c and the first rear sidewall 21c are disposed on a front side of the second rear sidewall 18c; an installation cavity 24c is defined between the first rear sidewall 21c and the second rear sidewall 18c, and the drain pipe 13c passes through the first rear sidewall 21c and has an external connection end 131c extending into the installation cavity 24c, the external connection end 131c being disposed at a position corresponding to the drain through hole 182c; the partition 20c, the first rear sidewall 21c, the bottom wall 15c, the left sidewall 16c, and the right sidewall 17c enclose to form a water tank 25c that is opened upwardly.

[0071] The water inlet assembly 30c includes a water inlet pipe 31c and a water valve assembly 32cc connected in series to the water inlet pipe 31c; the jetting assembly 40c includes a jetting pipe 41c and a water pump 42c connected in series to the jetting pipe 41c; an inlet of the water pump 42c and an outlet of the water inlet pipe 31c are disposed in the water tank 25c, and the jetting pipe 41c is in communication with the bedpan 12c.

[0072] In the embodiments, the seat 10c may be a single component or may be assembled from multiple components; the seat 10c may be an integrated ceramic structure since the water tank 25c has an opening facing upward and the installation cavity 24c is defined between the first rear sidewall 21c and the second rear sidewall 18c. The bedpan 12c is configured to receive excrement, and the jetting assembly 40c is configured to jet water into an inner cavity of the bidet main body 11c, such that the excrement is discharged through the drain pipe 13c. In order to achieve a water saving effect, the jet pipe 41c may be connected to two branches, one branch jetting water from an upper edge of the bedpan 12c and the other branch jetting water from an inlet of the drain pipe 13c. The shell 14c is not only a cosmetic part, but also provides support for the bedpan 12c. The seat 10c can be suspended and mounted by using a fastener through the hanging hole 181c and a vertical surface installation structure, such as a wall or a bracket. Both the water inlet assembly 30c and the jetting assembly 40c may be adopted from the related art; the water valve assembly 32c may be either a manual or electromechanical automatic valve, such as a solenoid valve, or a purely mechanical automatic valve.

[0073] As proposed by the present disclosure, the bidet 300 with an integrated built-in water tank is arranged with the partition 20c and the first rear sidewall 21c which can directly cooperate with the shell 14c to enclose to form the water tank 25c, thereby making full use of the irregular space at the rear portion of the seat 10c. Further, the water tank 25c is with a large capacity, and the setting of the water tank 25c does not affect the shape of the bidet main body 11c. The opening on an upper portion of the water tank 25c also facilitates the installation of a smart toilet cover, whereby a lower raised portion at a rear end of the smart toilet cover can be embedded in the water tank 25c, thereby making the overall height of the product lower, which in turn enhances the installation adaptability or reduces the space occupation.

[0074] Further, referring to FIGS. 16 to 18, 20, and 21 to 24, in some embodiments, the bidet 300 with an integrated built-in water tank further includes an overflow pipe 50c passing through the first rear sidewall 21c; an inlet end 51c of the overflow pipe 50c is disposed in the water tank 25c, and an outlet end 52c of the overflow pipe 50c extends into the installation cavity 24c. In this way, even if the water inlet assembly 30c malfunctions which results in overfilling, the excess water can be discharged from the inlet end 51c of the overflow pipe 50c, thereby reducing the risk of water leakage from the bidet. In addition, due to the structure of the overflow pipe 50c within the water tank 25c, the bidet is provided with a water level line defined by a mandatory standard.

[0075] Further, the outlet end 52c of the overflow pipe 50c is in communication with the external connection end 131c. In this way, the overflow pipe 50c and the drain pipe 13c can share a common connection to the external pipe.

[0076] Further, in order to facilitate lateral connection of the overflow pipe 50c to the external connection end 131c of the drain pipe 13c, the seat 10c further includes a connector 26c protruding on a rear surface of the first rear sidewall 21c and connected to an outer peripheral surface of the external connection end 131c; an inner cavity of the connector 26c is in communication with an inner cavity of the external connection end 131c. Referring together to FIG. 21, an overflow installation hole 22c is defined on the first rear sidewall 21c corresponding to the connector 26c and in communication with the inner cavity of the connector 26c, and the outlet end 52c of the overflow pipe 50c is sealingly fixed to the overflow installation hole 22c.

[0077] Further, in order to facilitate removable installation of the overflow pipe 50c with the first rear sidewall 21c and to ensure sealing between the overflow pipe 50c and the overflow installation hole 22c, an outer peripheral surface of the outlet end 52c of the overflow pipe 50c is arranged with a limiting flange 53c and an elastic snap 54c; the limiting flange 53c and the elastic snap 54c are spaced apart in a drainage direction of the overflow pipe 50c. The bidet 300 with an integrated built-in water tank further includes a sealing ring (not shown) sleeved on the outer peripheral surface of the outlet end 52c of the overflow pipe 50c, and the elastic snap 54c abuts against the rear surface of the first rear sidewall 21c; the sealing ring is pressed and clamped between the limiting flange 53c and a front surface of the first rear sidewall 21c, and is sealingly mated with the limiting flange 53c and the first rear sidewall 21c, respectively.

[0078] Further, the first rear sidewall 21c defines a water inlet installation hole 23c, and the water inlet assembly 30c further includes a water inlet fitting 36c; an outlet of the water inlet fitting 36c is in communication with an inlet of the water inlet pipe 31c; the water inlet fitting 36c is removably connected to the water inlet installation hole 23c; the partition 20c, the first rear sidewall 21c, the shell 14c, the bedpan 12c, and the connector 26c are of an integrated ceramic structure.

[0079] In the embodiments, the provision of the water inlet fitting 36c can facilitate connection of the water inlet pipe 31c to the municipal water pipe and support the water inlet pipe 31c. Since the water tank 25c is constructed of ceramic material and is integrally structured with the bidet main body 11c and the rest of the shell 14c, it is less likely to resonate with vibration of the water pump 42c, which can provide the user with a better silent experience.

[0080] Further, in order that the overflow pipe 50c also serves as an odor barrier, the overflow pipe 50c has a reservoir section 55c in the shape of an arch with a concave side facing upward.

[0081] Further, referring again to FIGS. 16 to 18, FIG. 20, and FIG. 25, in some embodiments, the water inlet assembly 30c further includes a water replenishment assembly 33c; the water replenishment assembly 33c includes a water replenishment valve 34c and a water replenishment pipe 35c; a water replenishment inlet of the water replenishment pipe 35c is connected to the water replenishment valve 34c, and a water replenishment outlet of the water replenishment pipe 35c is connected to the inlet end of the overflow pipe 50c.

[0082] In the embodiments, since the water level of the water tank 25c is too high and a scenario where overflow drainage is required through the overflow pipe 50c is in a low frequency, if the reservoir section 55c of the overflow pipe 50c is left standing for a long period of time after water is first added, an odor is generated from the water stored in the reservoir section 55c. When the reservoir section 55c is replenished by the water replenishment assembly 33c in a timely manner, the water stored in the reservoir section 55c can be replaced before the odor is generated. In addition, if the water in the reservoir section 55c is left standing for a long period of time, the water may evaporate, resulting in the odor in the drain pipe 13c entering the water tank 25c through the overflow pipe 50c and further overflowing into the ambient air outside the bidet 300 with an integrated built-in water tank. Therefore, by replenishing the water in the reservoir section 55c by the replenishment assembly 33c at appropriate time, it is possible for the overflow pipe 50c to always be in a water-tight condition.

[0083] Further, the inlet end of the overflow pipe 50c is arranged with an inlet grill defining an insertion hole, and the water replenishment outlet of the water replenishment pipe 35c is inserted with the insertion hole.

[0084] In the embodiments, by fixing the water replenishment outlet of the water replenishment pipe 35c, the bidet 300 with an integrated built-in water tank can be prevented from loosening from the inlet end of the overflow pipe 50c in a shaking environment. In addition, the grill hole on the inlet grill does not obstruct the water intake of the overflow pipe 50c.

[0085] Further, the shell 14c further includes a front sidewall 19c disposed on the front side of the partition 20c; a first opening 27c is defined between the front sidewall 19c and the partition 20c and disposed at the bottom and corresponding to the front portion of the bedpan 12c; a second opening 28c is defined between the front sidewall 19c and the first rear sidewall 21c and disposed at the bottom; the partition 20c, the first rear sidewall 21c, the shell 14c, and the bedpan 12c are of an integrated ceramic structure.

[0086] In the embodiments, since the first opening 27c and the second opening 28c are reserved and the water tank 25c has an opening facing upward, it is easy to reach the outer surface of the bidet main body 11c from the outside through the first opening 27c, and to reach sides of the first rear sidewall 21c and the second rear sidewall 18c facing each other through the second opening 28c, such that the setting of the water tank 25c does not affect the profile of the bidet main body 11c and the shaping of additional structures on the first rear sidewall 21c, such as the connector 26c.

[0087] In a fourth embodiment, referring to FIGS. 26 to 30, a bidet 400 with an integrated built-in water tank proposed in the present disclosure includes a seat 10d, a water inlet assembly 30d, a jetting assembly 40d, and an overflow pipe 50d.

[0088] The seat 10d includes a bidet main body 11d, a shell 12d, and a water tank 19d; the bidet main body 11d includes a bedpan 111d and a drain pipe 112d connected to the bedpan 111d; the shell 12d is disposed at a periphery of the bidet main body 11d.

[0089] The water inlet assembly 30d and the jetting assembly 40d are both disposed in the water tank 19d; the water inlet assembly 30d includes a water inlet pipe 31d, a water valve assembly 32d connected in series with the water inlet pipe 31d, and the jetting assembly 40d includes a jetting pipe 41d and a water pump 42d connected in series with the jetting pipe 41d; the jetting pipe 41d is in communication with the bedpan 111d.

[0090] An inlet end of the overflow pipe 50d extends into the water tank 19d.

[0091] In the embodiments, the seat 10d is a main structure; the water inlet assembly 30d and the jetting assembly 40d are disposed on the seat 10d; the bidet main body 11d and the shell 12d of the seat 10d may be adopted from the related art; the bedpan 111d is configured to receive excrement, and the jetting assembly 40d is configured to jet water into an inner cavity of the bidet main body 11d, so as to discharge the excrement into a pipe connected to a septic tank through the drain pipe 112d. The drain pipe 112d is usually arranged with a water reservoir for odor prevention, and the drain pipe 112d may be further arranged with an upwardly-arched curved portion to prevent backflow. The shell 12d is not only a cosmetic part, but also provides support for the bidet main body 11d. The seat 10d may be installed either on a bottom surface or on a vertical surface, such as on a wall or on a stand having a vertical installation surface. Both the water inlet assembly 30d and the jet assembly 40d may be adopted from the related art; the water valve assembly 32d may be either a manual valve or an electromechanical automatic valve, such as a solenoid valve, or a purely mechanical automatic valve. The overflow pipe 50d may extend into the water tank 19d at the inlet end only, or the overflow pipe 50d may be located entirely within the water tank 19d.

[0092] As proposed by the present disclosure, for the bidet 400 with an integrated built-in water tank, the inlet end of the overflow pipe 50d extends into the water tank 19d arranged with the water inlet assembly 30d and the jetting assembly 40d, such that even if the water inlet assembly 30d malfunctions and results in an overfilling of the water, the excess water can be discharged out of the inlet end of the overflow pipe 50d, which thereby reduces the risk of a leakage of the water from the bidet. Furthermore, due to the structure of the overflow pipe 50d within the water tank 19d, the bidet 400 with an integrated built-in water tank is provided with a water level line defined by a mandatory standard.

[0093] Further, the outlet end of the overflow pipe 50d is in communication with the drain pipe 112d. In this way, the overflow pipe 50d and the drain pipe 112d can share a common connection to an external pipe.

[0094] Further, referring to FIGS. 31 and 32 together, in some embodiments, the shell 12d includes a bottom wall 13d, and a lower portion of the drain pipe 112d is integrally connected to the bottom wall 13d; a position, of an upper surface of the bottom wall 13d, adjacent to the drain pipe 112d is arranged with an installation tab 20d being hollow; an inner cavity of the installation tab 20d is in communication with the drain pipe 112d, a top of the installation tab 20d defines an overflow installation hole 201d in communication with the inner cavity of the installation tab 20d, and a lower end of the overflow pipe 50d is sealingly fixed to the overflow installation hole 201d.

[0095] In the embodiments, the installation tab 20d is set such that the overflow pipe 50d can be arranged off-set from the drain pipe 112d, thereby enabling the realization of easier installation and a relatively compact installation structure.

[0096] Further, the shell 12d includes a front sidewall 14d, a bottom wall 13d, a left sidewall 15d, a right sidewall 16d, and a rear sidewall 17d, and a bottom opening 18d is defined between the front sidewall 14d and the bottom wall 13d facing a front portion of the bedpan 111d.

[0097] The seat 10d further includes a partition 21d extending upwardly from the bottom wall 13d, and the partition 21d, the bottom wall 13d, the left sidewall 15d, the right sidewall 16d, and the rear sidewall 17d enclose to form the water tank 19d; the water tank 19d is opened upwardly; the installation tab 20d, the partition 21d, the shell 12d, and the bedpan 111d are of an integrated ceramic structure.

[0098] In the embodiments, the overflow pipe 50d is integrally disposed within the water tank 19d. By providing the partition 21d, the shell 12d, and the bedpan 111d of an integrated ceramic structure, while retaining the bottom opening 18d, the upwardly-opened water tank is formed by enclosing the partition 21d, the bottom wall 13d, the left sidewall 15d, the right sidewall 16d, and the rear sidewall 17d, such that the space in a rear portion of the seat 10d is fully utilized, and the formed water tank has a large capacity and can cooperate with the water pump 42d for a long and stable flushing operation. Moreover, since the bottom opening 18d is retained and the water tank has an opening facing upward, an outer surface of the bidet main body 11d can be easily accessed from the outside, such that the setting of the water tank does not affect the shaping of the bidet main body 11d. The opening on an upper portion of the water tank also facilitates the installation of a smart toilet cover, whereby a lower raised portion at a rear end of the smart toilet cover can be embedded in the water tank, thereby making the overall height of the product lower, which in turn enhances the installation adaptability or reduces the space occupation. Since the water tank is constructed of ceramic material and is integrally structured with the bidet main body 11d and the rest of the shell 12d, it is less likely to resonate with vibration of the water pump 42d, which can provide the user with a better silent experience.

[0099] Further, referring to FIGS. 32 and 33, in some embodiments, in order to ensure that the overflow pipe 50d is quickly installed and the lower end of the overflow pipe 50d is sealed, an outer peripheral surface of the outlet end of the overflow pipe 50d is arranged with a limiting flange 511d and an elastic snap 512d; the limiting flange 511d and the elastic snap 512d are spaced apart in a drainage direction of the overflow pipe 50d, and the elastic snap 512d is positioned lower than the position of the limiting flange 511d; the bidet 400 with an integrated built-in cistern further includes a sealing ring 60d sleeved on the outer peripheral surface of the outlet end of the overflow pipe 50d, and the elastic snap 512d abuts against an inner surface of the installation tab 20d; the sealing ring 60d is pressed between the limiting flange 511d and the installation tab 20d and is sealingly mated with an upper surface of the limiting flange 511d and an upper surface of the installation tab 512d, respectively.

[0100] Further, referring to FIG. 26, FIG. 18, FIG. 30, FIG. 31, and FIG. 33, in some embodiments, the overflow pipe includes an odor barrier structure so as to prevent odorous gases within the drain pipe 112d from spilling out into the indoor environment through the overflow pipe 50d.

[0101] Further, the overflow pipe 50d includes an inline section 51d and a reservoir section 52d connected to an upper end of the inline section 51d, the inlet end of the overflow pipe 50d being formed in the reservoir section 52d, and the outlet end of the overflow pipe 50d being formed at a lower end of the inline section 51d.

[0102] In the embodiments, the reservoir section 52d is provided such that when water is stored in the reservoir section 52d, the odor in the drain pipe 112d can be prevented from overflowing into the indoor environment through the overflow pipe 50d. The specific shape of the reservoir section 52d may not be particularly limited in the embodiments, as long as the water can be smoothly drained and the air communication between the inlet end and the outlet end of the overflow pipe 50d can be blocked when the water level of the water tank 19d exceeds the inlet end of the overflow pipe 50d.

[0103] Further, the inline section 51d extends in a vertical direction, a main portion of the reservoir section 52d is in the shape of an arch with a concave side facing upward, and the reservoir section 52d has a connection port arranged downwardly and connected to the upper end of the inline section 51d.

[0104] In the embodiments, the arched reservoir section 52d has less internal resistance such that the overflow pipe 50d can drain faster; the reservoir section 52d can be more easily connected to the inline section 51d by providing the downward-facing connection port.

[0105] Further, the inline section 51d is disposed adjacent to the drain pipe 112d so as to better concentrate the drainage. In order to fully utilize the space of the water tank 19d and to avoid interference between the reservoir section 52d and the drain pipe 112d during installation, the reservoir section 52d is arranged on a side of the inline section 51d away from the drain pipe 112d.

[0106] Further, the rear sidewall 17d of the shell 12d is defines a water inlet installation hole 171d, and the water inlet assembly 30d further includes a water inlet fitting 34d; an outlet of the water inlet fitting 34d is in communication with an inlet of the water inlet pipe 31d; the water inlet fitting 34d is removably connected to the water inlet installation hole 171d.

[0108] In the embodiments, the water inlet fitting 34d can facilitate the connection of the water inlet pipe 31d to the municipal water pipe and support the water inlet pipe 31d. In some embodiments, an outlet of the water inlet pipe 31d is disposed close to the bottom wall 13d, such that less noise is generated during water replenishment. Since the water level of the water tank 19d is too high and a scenario where overflow drainage is required through the overflow pipe 50d is in a low frequency, if the reservoir section 52d of the overflow pipe 50d is left standing for a long period of time after water is first added, an odor is generated from the water stored in the reservoir section 52d. When the reservoir section 52d is replenished by the water replenishment assembly 33d in a timely manner, the water stored in the reservoir section 52d can be replaced before the odor is generated.
