Description

The present invention relates to toilet systems.

Patent Literature 1 discloses a waste conveying system in which a plurality of toilet bowls are arranged along a horizontal pipe. In this filth conveying system, the amount of flushing water that is flushed during normal use is suppressed to the amount necessary to discharge the filth in the toilet bowl to the horizontal pipe, and the number of times the toilet bowl is used or the number of usage time intervals is counted. When the number is reached, each toilet is supplied with a larger amount of flush water than when using a normal toilet, and the waste in the horizontal pipe is conveyed to the sewage pipe. By doing so, it is possible to prevent clogging of the horizontal piping with filth while saving water.

JP-A-2001-303639

A general-purpose toilet bowl is equipped with a water seal that includes an upward flow path in the drain pipe between the horizontal pipe and the toilet bowl, so it takes about 5 to 6 liters of flush water just to drain the waste in the toilet bowl. need to flow. Therefore, when this general-purpose type toilet is applied to the toilet system of Patent Document 1, it becomes impossible to discharge the filth inside the toilet in situations where the amount of flushing water used should be suppressed to, for example, about 1 liter, such as in the event of a disaster. is concerned.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional circumstances, and an object of the present invention is to enable transport of wastes in horizontal pipes even during water saving.

The present invention
a plurality of toilet bowl devices each having a drainage port communicable with the horizontal pipe and arranged along the horizontal pipe;
a flapper valve provided in the toilet device, biased in a valve closing direction to close the drain port, and communicating the drain port with the horizontal pipe when the valve is open;
a flush water tank provided in the toilet device and storing flush water to be supplied to the toilet bowl;
a conveying water supply device that can be connected to a portion of the horizontal pipe that is upstream of a connection portion with the plurality of toilet devices and that is capable of supplying wash water to the horizontal pipe;
supply mode changing means capable of switching between a normal mode in which a large amount of flushing water is supplied to the toilet bowl and a water saving mode in which a smaller amount of flushing water is supplied to the toilet bowl than in the normal mode ; ,
The supply mode changing means is
a ball chain whose upper end is connected to a lever;
a valve body connected to the lower end of the ball chain for opening and closing a water supply port of the wash water tank;
and a float attached to the ball chain,
The float can be changed between a buoyancy imparting form in which buoyancy is imparted to the valve body and a buoyancy cancellation form in which buoyancy is released from being imparted to the valve body, while the float remains attached to the ball chain. There is .

During normal times when the amount of water supplied to the toilet device is not limited, the supply mode changing means is set to the normal mode to increase the amount of flush water supplied to the toilet bowl. As a result, the filth in the toilet bowl, which has been discharged from the toilet bowl to the horizontal pipe by opening the flapper valve, is discharged from the horizontal pipe to the sewage pipe by the flow of the flushing water supplied to the toilet bowl. be. To reduce flush water consumption by changing a supply mode changing means to a water saving mode to reduce the amount of water supplied to a toilet bowl during water saving when the amount of water supplied to a toilet device is limited, such as in the event of a disaster. can be done. In the water-saving mode, the waste in the toilet bowl is discharged from the toilet bowl into the horizontal pipe by opening the flapper valve, but does not reach the sewage pipe. By supplying washing water to the horizontal pipe from the conveying water supply device, the filth remaining in the horizontal pipe can be conveyed to the sewage pipe. In normal times, if the float is in a buoyancy-imparting form, the supply mode changing means will be in the normal mode, and the opening time of the water supply port will be longer, so the amount of water supplied from the flush water tank to the toilet bowl will increase. During water saving, if the float is changed to the buoyancy canceling mode, the supply mode changing means will switch to the water saving mode, and the opening time of the water supply port will be shortened. can. Also, since the amount of cleaning water used is small during water-saving mode, if cleaning water is stored in the cleaning water tank in the water-saving mode, multiple cleaning operations can be performed even when the cleaning water tank is full. . Therefore, it is not necessary to carry out the troublesome task of pouring washing water into the toilet bowl using a bucket or the like each time the toilet device is used.

In the following description, regarding the front-rear direction, the left side in FIGS. 2 and 3 is defined as the front. As for the vertical direction, the directions appearing in FIGS. 1 to 7 are defined as upward and downward as they are.

<Overall Configuration of Toilet System A>
The toilet system A of the first embodiment is provided in public facilities (for example, schools, etc.), commercial facilities, etc., and is arranged above one horizontal pipe 10 provided under the floor of the facility. . The toilet system A is configured by arranging one conveying water supply device 11 and a plurality of toilet devices 17 in a row along the piping direction (longitudinal direction) of the horizontal pipe 10 . The conveying water supply device 11 is arranged at the most upstream position in the piping direction of the horizontal pipe 10, and the plurality of toilet bowl devices 17 are arranged at appropriate intervals in the area downstream of the conveying water supply device 11. there is A downstream end of the lateral pipe 10 is connected to a sewage pipe 16 .

The toilet system A can discharge filth in the toilet device 17 (toilet bowl portion 19) to the side of the horizontal pipe 10 in both the normal state and the water-saving state, and the filth in the horizontal pipe 10 can be reliably discharged to the sewage pipe 16. It can be transported to In this embodiment, "normal" is defined as a state in which the lifeline functions normally and the required amount of water can be supplied from the water supply equipment to the transportation water supply device 11 and the toilet device 17 . "During water conservation" is defined as a state in which water is no longer supplied from the water supply equipment to the transportation water supply device 11 and the toilet device 17 due to a lifeline stoppage or temporary water outage due to a disaster.

<Conveying water supply device 11>
The conveying water supply device 11 includes a water tank 12 with an open upper surface and a water supply pipe 13 . The water supply pipe 13 is provided with a trap (not shown) and cut off from the sewage pipe 16 . The upper end (upstream end) of the water supply pipe 13 is connected to the bottom of the water tank 12 , and the lower end (downstream end) of the water supply pipe 13 is connected to the horizontal pipe 10 via the communication pipe 14 . The water supply pipe 13 and the communication pipe 14 constitute a water supply passage 15 that allows the water tank 12 and the horizontal pipe 10 to communicate with each other.

The water supply channel 15 is a straight path that extends straight in the vertical direction. The water poured into the water tank 12 flows down the water supply pipe 13 and into the horizontal pipe 10 , and functions as washing water W for conveying the waste in the horizontal pipe 10 to the sewage pipe 16 . Since the water supply pipe 13 is a vertical straight pipe, the wash water W in the water tank 12 flows down the water supply pipe 13 vigorously and reaches the horizontal pipe 10 while maintaining the flow force.

<Toilet device 17>
The toilet device 17 includes a toilet body 18 installed on the floor of the facility, a flapper valve 24 attached to the toilet body 18, and a flush water tank 28 attached to the toilet body 18. - 特許庁The toilet body 18 has a toilet bowl portion 19 with an open upper surface, a drain port 20 opening downward at the bottom portion of the toilet bowl portion 19, and a drain hole 21 extending downward from the drain port 20. . An upstream end of a drain pipe 22 is connected to the lower end of the drain hole 21 .

The drain hole 21 and the drain pipe 22 form a drain passage 23 for draining the waste in the toilet bowl portion 19 together with the wash water W to the horizontal pipe 10 . The route from the upstream end (drain port 20) of the discharge channel 23 to the downstream end (horizontal pipe 10) is a linear route that extends substantially straight in the vertical direction.

<Flapper valve 24>
The flapper valve 24 functions as means for opening and closing the drain port 20 . The flapper valve 24 includes a flap 25 that swings vertically about a horizontal axis extending in the horizontal direction, and a valve closing spring 26 that biases the flap 25 in the valve closing direction. The valve closing spring 26 is mounted between a link arm 27 formed on the flap 25 and the toilet body 18 . The flapper valve 24 is normally held in a closed state (see FIG. 2) in which the flap 25 closes the drain port 20 due to the elasticity of the valve closing spring 26 . In the valve closed state (see FIG. 3), the toilet bowl 19 is liquid-tightly shielded from the discharge passage 23 and the horizontal pipe 10, so that flush water W is stored in the toilet bowl 19. kept in

When a turning force exceeding the elasticity of the valve closing spring 26 acts on the flap 25 in the valve closed state, the flap 25 swings in the valve opening direction, and the drain port 20 is opened. When the drain port 20 is opened, the inside of the toilet bowl portion 19 communicates with the drain passage 23 and the horizontal pipe 10, so that the washing water W and the waste in the toilet bowl portion 19 pass through the drain passage 23 and are pulled sideways. It is discharged into the pipe 10. Since the discharge path 23 is a straight path in the vertical direction without an ascending path, the wash water W and wastes in the toilet bowl 19 fall to the horizontal pipe 10 due to their own weight.

A first arm portion 45 projecting radially outward from the swing shaft 39 is formed at the inner end portion of the swing shaft 39 that is accommodated in the outer tank 29 . The upper end of the ball chain 41 is connected to the first arm portion 45 , and the ball chain 41 hangs down from the first arm portion 45 inside the inner tank 30 .

A valve body 42 is connected to the lower end of the ball chain 41 . The valve body 42 is attached to the bottom of the inner tank 30 so as to be able to swing vertically. When the valve body 42 rises, the water supply port 31 is opened, the float valve 38 is opened, and the flush water W stored in the inner tank 30 is supplied to the toilet bowl portion 19 . When the valve body 42 descends, the water supply port 31 is closed, the float valve 38 is closed, and the supply of flush water W from the inner tank 30 to the toilet bowl 19 is stopped. The float 43 is attached to the ball chain 41 so as to be relatively displaceable along the length direction.

A stop ring 44 is fixedly attached to the ball chain 41 at a position above the float 43 . The float 43 is restricted from moving upward relative to the ball chain 41 by contacting the stop ring 44 . By fixing the stop ring 44 to the ball chain 41, the float 43 is in a buoyancy-imparting configuration capable of imparting buoyancy to the valve body 42, and the float valve 38 supplies water from the waterworks equipment to the wash water tank 28 without hindrance. The normal mode corresponding to the normal time is set.

<Valve opening operation mechanism 46>
The toilet device 17 is provided with a valve-opening operation mechanism 46 as a means for opening the flapper valve 24 and the float valve 38 substantially simultaneously by one-action operation of the lever 40 . The valve opening operation mechanism 46 includes a first link bar 47 , a second link bar 48 and a swing bracket 49 in addition to the swing shaft 39 and the lever 40 . A second arm portion 50 extending radially outward from the swing shaft 39 is formed at a position corresponding to the working space 32 in a plan view of the swing shaft 39 .

The upper end of the first link bar 47 housed in the working space 32 is connected to the second arm portion 50 . The first link bar 47 penetrates the bottom wall of the outer tank 29 , and the lower end of the first link bar 47 is connected to the swing bracket 49 . A rear end portion of a second link bar 48 arranged below the wash water tank 28 is connected to the swing bracket 49 . A front end of the second link bar 48 is connected to the link arm 27 of the flap 25 . The link arm 27 and the second link bar 48 are always urged forward by the elastic restoring force of the valve closing spring 26 .

<Inner lid 51>
The inner lid 51 is a single member made of synthetic resin, and includes a lid body portion 52 , a peripheral wall portion 53 , a water inlet 54 and a bottle holding portion 58 . The lid main body 52 has a substantially horizontal plate shape as a whole, and covers substantially the entire opening of the upper surface of the inner tank 30 . The peripheral wall portion 53 rises upward from the entire area of the outer peripheral edge of the lid main body portion 52 .

The water inlet 54 is formed by cutting a portion of the lid main body 52 so as to penetrate from the upper surface to the lower surface. A skirt portion 55 is formed on the lower surface of the lid main body portion 52 so as to protrude downward along the opening edge of the water inlet 54 in a cylindrical shape. An inclined surface 56 is formed on the upper surface of the lid main body 52 so as to gradually decrease from the right edge (outer peripheral edge) of the lid main body 52 toward the left (toward the water inlet 54). Similarly, an inclined surface 56 is formed on the upper surface of the lid main body 52 so as to gradually decrease from the left edge (peripheral edge) of the lid main body 52 toward the right side (the water inlet 54 side).

The inner lid 51 is formed with a plurality of support plate portions 57 extending from the inner peripheral surface of the skirt portion 55 toward the central portion of the water inlet 54 . Extending end portions of the plurality of support plate portions 57 are connected to the outer peripheral surface of a bottle holding portion 58 having a tubular shape that is circular in plan view. That is, the bottle holding portion 58 is arranged in the opening area of the water inlet 54 while being separated from the inner peripheral surface of the skirt portion 55 (opening edge of the water inlet 54 ) by the plurality of support plate portions 57 . A guide edge portion 59 that is inclined downward toward the bottle holding portion 58 is formed in a region of the upper edge portions of the plurality of support plate portions 57 that is connected to the bottle holding portion 58 .

A cover portion 60 is formed in a region of the inner lid 51 corresponding to the overflow port 34 in plan view. The covering portion 60 is arranged above the overflow port 34 and has a shape that covers the entire overflow port 34 in plan view. A portion of the overflow port 34 overlaps the area surrounded by the skirt portion 55 in plan view. The cover portion 60 continues to the lower edge portion of the skirt portion 55 and the lower edge portion of a part of the support plate portion 57 .

The inner lid 51 is formed with a guide tube portion 61 that penetrates vertically from the upper surface to the lower surface of the lid main body portion 52 . A float 62 is inserted through the guide tube portion 61 so as to be vertically movable relative to the inner lid 51 . The float 62 has an elongated bar shape as a whole in the vertical direction. The specific gravity of the float 62 is set smaller than that of water. When the float 62 is floated on the water, the upper end region of the float 62 keeps protruding upward from the water surface. An upper end portion of the portion of the float 62 protruding above the water surface functions as an indicator portion 63 .

<Usage pattern in normal times>
In the toilet device 17, the lever 40 and the pivot shaft 39 are always held at their initial positions by the elastic restoring force of the valve closing spring 26, and the flapper valve 24 and the float valve 38 are kept closed. In the float valve 38, the float 43 is in the buoyancy-imparting mode, and the float valve 38 is in the normal mode. The flush water tank 28 is filled with 10 liters or more of water supplied from the water supply system as flush water W, and the toilet bowl 19 stores approximately 600 cc of flush water W.

After using the toilet device 17, when the lever 40 is rotated in the washing direction against the elasticity of the valve closing spring 26, the ball chain 41 is pulled up and the valve body 42 swings upward, thereby opening the water supply port. 31 is opened, the float valve 38 is opened, and the flush water W in the flush water tank 28 is supplied to the toilet bowl portion 19 . Even if the lever 40 is released immediately after rotating the lever 40, the valve body 42 keeps the water supply port 31 open by the buoyancy of the float 43 while the water level of the wash water W is higher than a predetermined position. . As a result, the float valve 38 is kept open for a certain period of time, so that the amount of flush water W supplied from the flush water W to the toilet bowl 19 is relatively large, about 5 to 6 liters. .

Further, when the lever 40 is rotated in the washing direction, the float valve 38 is opened and the flapper valve 24 is also opened. At this time, the first link bar 47 is raised by the rotation of the lever 40, the swing bracket 49 is rotated, the second link bar 48 is displaced rearward, the flap 25 is swung downward, and the drain port 20 is closed. is released. When the flapper valve 24 opens, the filth in the toilet bowl 19 flows down along with the flush water W in the discharge passage 23. - 特許庁

As described above, since the amount of wash water W supplied from the wash water tank 28 to the toilet bowl 19 is as large as 5 to 6 liters, the filth discharged into the horizontal pipe 10 is multiplied by a large amount of wash water W. It is conveyed to the sewage pipe 16 . Therefore, in normal times, only with the flush water W supplied from the flush water tank 28 to the toilet bowl 19, the waste in the toilet bowl 19 can be discharged to the horizontal pipe 10, and the waste can be discharged to the horizontal pipe 10. Waste can be conveyed down the sewer 16 . When the lever 40 is released, the flapper valve 24 is closed by the force of the valve closing spring 26, but the flush water W is supplied from the flush water tank 28 to the toilet bowl 19 even after the flapper valve 24 is closed. Therefore, about 600 cc of cleansing water W is stored in the toilet bowl portion 19 .

<Usage form when saving water>
When the water supply to the flushing water tank 28 is stopped due to a disaster, failure of water supply equipment, etc., the float valve 38 of each toilet device 17 reduces the amount of flushing water W supplied from the flushing water tank 28 to the toilet bowl 19. make changes for Specifically, first, the outer lid 66 is removed from the outer tank 29 and the inner lid 51 is removed from the inner tank 30 . In this state, the stop ring 44 is removed from the ball chain 41 so that the float 43 can move upward along the ball chain 41 freely.

As a result, the float 43 is disconnected from the valve body 42 from the buoyancy imparting mode (form for normal use) in which the float 43 is connected to the valve body 42 via the ball chain 41 to impart buoyancy to the valve body 42 . The valve body 42 is changed to a buoyancy canceling mode (a mode for when the water supply is interrupted) in which buoyancy is not applied. When the float 43 is changed to the buoyancy release mode, the float valve 38 is changed from the normal mode to the water saving mode. After changing the float 43 to the buoyancy cancellation mode, the inner lid 51 is attached to the inner tank 30 .

After using the toilet device 17 in the water-saving mode, the lever 40 is rotated in the washing direction and the hand is immediately released from the lever 40 in the same manner as in normal times. When the lever 40 is rotated, the valve body 42 swings upward, so that the float valve 38 opens and the wash water W in the wash water tank 28 is supplied to the toilet bowl portion 19 . When the lever 40 is released, the bias of the valve closing spring 26 returns the lever 40 to its initial position. When the lever 40 returns to the initial position, the valve body 42 not receiving the buoyant force of the float 43 immediately swings downward due to its own weight and the water pressure (the pressure of the wash water W) in the wash water tank 28 to open the water supply port 31 . Since it is blocked, the float valve 38 is closed. Since the valve body 42 opens the water supply port 31 for a short time, the amount of flush water W supplied from the flush water tank 28 to the toilet bowl 19 is about 1 liter, which is less than normal.

Further, when the lever 40 is rotated in the cleaning direction, the float valve 38 opens and the flapper valve 24 opens at the same time as in normal times, so that the waste in the toilet bowl portion 19 and the cleaning water W flow into the horizontal pipe 10. Ejected. When the lever 40 is released, the flapper valve 24 is closed, so that approximately 600 cc of cleansing water W is stored in the toilet bowl 19 as in normal times. As described above, in the state where the float 43 is changed to the buoyancy canceling mode, the amount of flush water W supplied from the flush water tank 28 to the toilet bowl 19 is smaller than in normal times. The filth discharged into the pipe 10 does not reach the sewage pipe 16 and stays in the horizontal pipe 10.例文帳に追加

In order to convey the filth remaining in the horizontal pipe 10 to the sewage pipe 16, the conveying water supply device 11 is used. Specifically, a large amount of cleansing water W is poured into the water tank 12 in consideration of the frequency of use of the toilet device 17 and the like. A large amount of washing water W poured into the water tank 12 vigorously flows down the vertical water supply pipe 13 and flows into the horizontal pipe 10, and entangles the filth accumulated in the horizontal pipe 10 while maintaining the water force. It flows out to the sewage pipe 16 . In this way, the filth in the horizontal pipe 10 is collectively transported to the sewage pipe 16 by the washing water W poured into the transport water supply device 11 .

In addition, as a mode of use of the conveying water supply device 11, the upper end of the water supply pipe 13 at the bottom of the water tank 12 is closed with a plug (not shown), the wash water W is stored in the water tank 12, and the plug (not shown) is used. ) may be removed to supply the wash water W in the water tank 12 to the horizontal pipe 10 .

During water saving, the task of replenishing the cleaning water tank 28 with the cleaning water W can be performed with the inner lid 51 attached to the inner tank 30 . For water supply to the inner tank 30, a container with a large volume such as a bucket, or a drink bottle 64 (PET bottle) or a ladle (not shown) with a volume smaller than that of the bucket can be used.

When water is supplied from a bucket, the water in the bucket is poured toward the water inlet 54 of the inner lid 51. - 特許庁At this time, even if part of the water comes off the water inlet 54 and flows on the upper surface of the lid main body 52 toward the outer peripheral side, the peripheral wall 53 rises on the outer peripheral edge of the inner lid 51. There is no fear that the water on the upper surface of 52 overflows into the working space 32 between the inner tank 30 and the outer tank 29 .

The water that flows out of the water inlet 54 and flows toward the left and right ends of the upper surface of the lid main body 52 returns to the water inlet 54 side due to the inclination of the inclined surface 56 . In addition, since the cover portion 60 is provided above the overflow port 34, there is no fear that the water poured into the water inlet 54 from the bucket will be discharged to the toilet bowl portion 19 through the overflow port 34. Absent.

When supplying water with the beverage bottle 64, the beverage bottle 64 is turned upside down, the spout 65 is inserted into the bottle holding portion 58, and the shoulder portion (dome-shaped portion around the spout 65) of the beverage bottle 64 is pushed. It is placed on the guide edge 59 . As a result, the posture of the beverage bottle 64 is stabilized and there is no fear of the beverage bottle 64 tilting, so even if the beverage bottle 64 is not held by hand, water can be supplied from the beverage bottle 64 to the inner tank 30 (washing water tank 28). It can be carried out.

Moreover, when the inner lid 51 is attached to the inner tank 30 , it is preferable that the float 62 is inserted into the guide tube portion 61 and floated on the washing water W in the inner tank 30 . When the amount of stored wash water W is large, the indicator portion 63 at the upper end of the float 62 protrudes greatly upward from the wash water tank 28 (inner lid 51). The height of the portion 63 is reduced. In this manner, by visually observing the height of the indicator portion 63, the water level (reserved water amount) of the cleaning water W in the cleaning water tank 28 can be determined. can be measured.

The toilet system A includes a plurality of toilet devices 17, one conveying water supply device 11, and a float valve 38 (supply mode changing means). Each toilet bowl device 17 has a form in which a drain port 20 that can communicate with the lateral pipe 10 is opened in the bottom portion of the toilet bowl portion 19 . A plurality of toilet devices 17 are arranged along the horizontal pipe 10 . The toilet device 17 is provided with a flapper valve 24 that is urged in the valve closing direction to close the drain port 20 of the toilet bowl portion 19 and communicates the drain port 20 with the lateral pipe 10 when the valve is open. The conveying water supply device 11 is connected to a portion of the lateral pipe 10 upstream of the connection portions with the plurality of toilet devices 17 so as to supply flush water W to the lateral pipe 10 . The float valve 38 can be switched between a normal mode in which a large amount of flush water W is supplied to the toilet bowl 19 and a water saving mode in which a smaller amount of flush water W is supplied to the toilet bowl 19 than in the normal mode . .

During normal times when the amount of water supplied to the toilet device 17 is not limited, the float valve 38 is set to the normal mode to increase the amount of flush water W supplied to the toilet bowl portion 19 . As a result, the filth in the toilet bowl 19 discharged from the toilet bowl 19 to the side-drawing pipe 10 by opening the flapper valve 24 is multiplied by the flow of the flush water W supplied to the toilet bowl 19 and pulled sideways. It is discharged from the pipe 10 to the sewage pipe 16 . On the other hand, when the amount of water supplied to the toilet device 17 is limited (during water saving), such as during a disaster, the amount of water supplied to the toilet bowl 19 can be reduced by changing the float valve 38 to the water saving mode. For example, the consumption of cleaning water W can be reduced. In the water-saving mode, waste in the toilet bowl 19 is discharged from the toilet bowl 19 to the horizontal pipe 10 by opening the flapper valve 24, but does not reach the sewage pipe 16. - 特許庁However, the filth remaining in the horizontal pipe 10 can be transported to the sewage pipe 16 by supplying the cleaning water W from the transport water supply device 11 to the horizontal pipe 10 .

Further, the toilet device 17 is provided with a flush water tank 28 for storing flush water W to be supplied to the toilet bowl portion 19, and the flush water tank 28 is provided with the float valve 38 described above. The float valve 38 includes a valve body 42 for opening and closing the water supply port 31 of the flush water tank 28 and a float 43, and is originally used to supply and stop flush water W from the flush water tank 28 to the toilet bowl 19. It has a valve function to perform. The float 43 can be changed between a buoyancy imparting form that imparts buoyancy to the valve body 42 and a buoyancy cancellation form that releases the buoyancy to the valve body 42 . By providing the float 43 with this changing function, the float valve 38 also functions as the above-described supply mode changing means.

In normal times, if the float 43 is set to the buoyancy mode, the float valve 38 will be in the normal mode, and the open time of the water supply port 31 will be lengthened, so the amount of water supplied from the wash water tank 28 to the toilet bowl 19 will increase. When the float 43 is changed to the buoyancy canceling mode during water saving, the float valve 38 becomes the water saving mode and the opening time of the water supply port 31 is shortened, so the amount of water supplied from the washing water tank 28 to the toilet bowl part 19 is reduced. be able to. In addition, since the amount of washing water W used per time is small in the water saving mode, if the washing water tank 28 is filled with washing water W in the water saving mode, the washing water tank 28 can be used a plurality of times. Washing operation becomes possible. Therefore, the troublesome task of pouring flush water W into the toilet bowl portion 19 with a bucket or the like each time the toilet device 17 is used is not required.

The toilet device 17 also includes an inner tank 30 (wash water tank 28) capable of storing wash water W to be supplied to the toilet bowl portion 19, and an inner lid 51 attached to an opening on the upper surface of the inner tank 30. It has The inner lid 51 is formed with a water inlet 54 that allows water to be injected into the inner tank 30 . According to this configuration, it is possible to replenish the cleaning water W into the cleaning water tank 28 even when the inner lid 51 is attached to the cleaning water tank 28 when water is saved (when the water supply is cut off). Since the water injection port 54 is formed with a bottle holding portion 58 capable of holding the drinking spout 65 of the beverage bottle 64, by fitting the drinking spout 65 of the beverage bottle 64 into the bottle holding portion 58, the washing water tank can be opened. The work of replenishing water to 28 is facilitated.

Further, the inner lid 51 is formed with a peripheral wall portion 53 that rises along the outer peripheral edge of the inner lid 51 . The peripheral wall portion 53 is arranged so as to surround the water inlet 54 over the entire circumference. Therefore, when pouring a large amount of water into the cleaning water tank 28 (inner tank 30) from the water inlet 54 using a bucket or the like, even if part of the water adheres to the upper surface of the inner lid 51, the water will There is no possibility that the liquid will flow down from the outer peripheral edge of the lid 51 .

A sloped surface 56 is formed on the upper surface of the inner lid 51 so as to slope downward from the outer peripheral side of the inner lid 51 toward the water inlet 54 side. Therefore, even if part of the water adheres to the upper surface of the inner lid 51 when water is poured from the water inlet 54 into the inner tank 30 (washing water tank 28), the water is Since it is guided to 54, the amount of water remaining on the upper surface of the inner lid 51 can be reduced.

An overflow pipe 33 having an upwardly opening overflow port 34 is provided in the cleaning water tank 28 (inner tank 30), and the inner lid 51 is provided with a space above the overflow port 34. A cover portion 60 is formed. According to this configuration, it is possible to prevent part of the water from flowing into the overflow pipe 33 when injecting water into the cleaning water tank 28 from the water injection port 54 .

The toilet device 17 also includes a flush water tank 28 (inner tank 30) capable of storing flush water W to be supplied to the toilet bowl portion 19, and an inner tank 30 from the outside of the flush water tank 28 in plan view. A float 62 is provided to allow visual observation of the water level. The float 62 has a lower specific gravity than water and has an index portion 63 that protrudes upward from the water surface while floating on the water. At least the indicator portion 63 of the float 62 can be visually observed from the front or side of the wash water tank 28 . Therefore, the height between the index portion 63 and the upper end of the washing water tank 28 (outer tank 29) can be visually compared without removing the inner lid 51 and looking into the inside of the washing water tank 28 (inner tank 30). Alternatively, the water level in the wash water tank 28 can be confirmed by visually checking whether the indicator portion 63 protrudes upward from the wash water tank 28 .
