However, since a part of the operating member is immersed in the cleaning water in the tank, the cleaning water in the tank may enter the drive unit through the operating member due to the capillary phenomenon and damage the internal electrical parts. is there.

It is an object of the disclosed embodiment to provide a flush toilet device and a drain valve drive unit capable of preventing the wash water in the wash water tank from entering the drive unit through the operating member.

The flush toilet device according to one aspect of the embodiment is arranged in the toilet body, the wash water tank for storing the wash water supplied to the toilet body, and the wash water tank, and is moved up and down. A drain valve device including a drain valve for opening and closing the drain port of the washing water tank and a drive unit for driving the drain valve included in the drain valve device are provided, and the drive unit includes a drive unit operated by electric power and the drive unit. An elongated drain valve side operating member having one end connected to the drain valve, an elongated driving unit operating member having one end connected to the driving unit, the drain valve side operating member, and the driving unit side. A connection portion for connecting the drain valve side operation member and the drive unit side operation member is provided with the other ends of the operation member separated from each other.

The operation member for connecting the drain valve and the drive unit is physically divided into the drain valve side operation member and the drive unit side operation member, and the end portions are separated from each other and connected by the connection portion. As a result, even if the cleaning water in the cleaning water tank rises along the drain valve side operating member due to the capillary phenomenon, the cleaning water can be prevented from being transmitted from the drain valve side operating member to the driving unit side operating member. it can. Therefore, according to the flush toilet device according to one aspect of the embodiment, it is possible to prevent the wash water in the wash water tank from entering the drive unit through the operation member, and the water wash toilet device is arranged inside the drive unit. It is possible to prevent the failure of electrical parts.

Further, the connecting portion is characterized by including a pulley having a first groove portion over which the drain valve side operating member is bridged and a second groove portion over which the driving portion side operating member is bridged.

By repeating the operation of pulling the operating member and the operation of returning it to the original position, the operating member may be bent or broken around the connecting portion. Therefore, the drain valve side operation member and the drive unit side operation member are connected by a pulley. According to this configuration, when the drain valve side operation member and the drive unit side operation member move with the operation of pulling the operation member or the operation of returning the operation member, the pulley causes the drain valve side operation member and the drive unit side operation member to move. By guiding, it is possible to make it difficult for them to bend or break. Further, by connecting the drain valve side operation member to the first groove portion and the drive unit side operation member to the second groove portion, contact between the drain valve side operation member and the drive unit side operation member is prevented. Therefore, it is possible to prevent the washing water from being transmitted from the drain valve side operating member to the driving unit side operating member through the contact portion.

Further, the pulley is arranged at a distance from the first pulley portion having the first groove portion and the first pulley portion, the second pulley portion having the second groove portion, the first pulley portion and the pulley. It is characterized by including a shaft portion that integrally rotates the second pulley portion.

By configuring the first pulley portion having the first groove portion and the second pulley portion having the second groove portion at intervals, the cleaning water from the drain valve side operating member to the driving part side operating member is arranged. Transmission can be prevented more reliably.

Further, the connecting portion includes a casing portion for accommodating the pulley, and the casing portion has a partition plate between the first pulley portion and the second pulley portion.

By providing a partition plate between the first pulley portion and the second pulley portion, it is possible to more reliably prevent the transmission of the washing water from the drain valve side operating member to the driving unit side operating member.

Further, the first pulley portion and the second pulley portion are arranged side by side in the vertical direction, and the first pulley portion is arranged below the second pulley portion.

By arranging the first pulley portion below the second pulley portion, it is possible to prevent the transmission of the washing water from the drain valve side operating member to the driving unit side operating member. That is, it is possible to prevent the washing water that has risen along the drain valve side operating member from falling due to gravity and adhering to the driving unit side operating member. Further, by arranging the first pulley portion and the second pulley portion side by side in the vertical direction, the height dimension of the connecting portion can be suppressed to be small, so that it is possible to prevent the washing water tank from becoming large.

Further, the first pulley portion is characterized by having one or a plurality of through holes penetrating in the vertical direction.

Even if the cleaning water that has risen up the drain valve side operating member due to the capillary phenomenon reaches the first pulley portion, the cleaning water can be released from the through hole. Therefore, it is possible to more reliably prevent the transmission of the washing water from the drain valve side operating member to the driving unit side operating member.

Further, the pulley has a plan-viewing fan shape, and has a first fixing portion for fixing the other end of the drain valve side operating member on one end side of the arc in the fan shape, and the other end side of the arc. It is characterized by having a second fixing portion for fixing the other end portion of the drive portion side operating member.

By providing the first fixing portion on one end side of the arc in the fan shape and providing the second fixing portion on the other end side of the arc, the drain valve side operating member and the driving portion side operating member overlap each other in a plan view. Will be bridged over the pulley. As a result, a large area where the drain valve side operation member and the drive unit side operation member are guided by the pulley can be secured, so that the drain valve side operation member and the drive unit side operation member are more bent or broken. It can be made difficult.

Further, the connecting portion is arranged inside the washing water tank, and the driving portion is arranged outside the washing water tank.

By arranging the connecting part inside the washing water tank, even if the washing water that has raised the drain valve side operating member due to the capillary phenomenon reaches the connecting part and leaks from the connecting part, it leaks out. Since the washed water returns to the inside of the washing water tank, there is no possibility that the toilet room gets wet with the washing water. Further, by arranging the drive unit outside the washing water tank, it is possible to suppress the increase in size of the washing water tank.

According to one aspect of the embodiment, it is possible to provide a flush toilet device and a drain valve drive unit capable of preventing the wash water in the wash water tank from entering the drive unit through the operating member. ..

Hereinafter, embodiments of the flush toilet device and the drain valve drive unit disclosed in the present application will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments shown below.

<1. Overall configuration of flush toilet device>
First, the overall configuration of the flush urinal device according to the present embodiment will be described with reference to FIG. FIG. 1 is an overall perspective view showing an example of the configuration of a flush toilet device.

In this specification, the vertical upward direction is referred to as "upward" and the vertical downward direction is referred to as "downward". Further, when viewed from the user facing the toilet body 2, the front side of the toilet body 2 is described as "front", the back side is described as "rear", the right side is described as "right side", and the left side is described as "left side".

As shown in FIG. 1, the flush toilet device 1 includes a toilet body 2 and a flush water tank 3. The toilet bowl main body 2 is, for example, a Western-style toilet bowl made of earthenware, and includes a bowl portion 21 and a drain trap pipeline 22 communicating with the lower portion of the bowl portion 21. The bowl portion 21 is formed with a spout 23 for spouting wash water supplied from a headrace (not shown) formed inside the toilet bowl main body 2, and the wash water spouted from the spout 23 is discharged. It is designed to descend while turning to wash the bowl portion 21. The drain trap pipeline 22 is provided with an opening on one end side below the pool surface W0 of the washing water stored in the bowl portion 21, and the opening on the other end side is via a drainage socket (not shown). It is connected to an underfloor drain pipe (not shown).

The wash water tank 3 is arranged on the upper surface of the toilet bowl main body 2 on the rear side, and stores the wash water supplied to the toilet bowl main body 2. The wash water tank 3 may be integrally formed with the toilet bowl main body 2 (so-called one-piece type).

<2. Internal configuration of wash water tank>
Next, the internal configuration of the washing water tank 3 will be described with reference to FIG. FIG. 2 is a schematic view showing an example of the internal configuration of the washing water tank 3.

As shown in FIG. 2, the bottom 31 of the wash water tank 3 is formed with a drain port 32 that communicates with the headrace (not shown) of the toilet bowl main body 2, and the wash water in the wash water tank 3 is , The drainage port 32 is supplied to the headrace (not shown) of the toilet bowl main body 2.

Inside the wash water tank 3, a water supply device 4, a drain valve device 5, and a drain valve drive unit 6 are arranged.

The water supply device 4 is a device for supplying washing water to the inside of the washing water tank 3. Specifically, the water supply device 4 is attached to a water supply pipe 41 connected to an external water supply source (not shown) and an upper end portion of the water supply pipe 41, and discharges washing water supplied from the water supply pipe 41. It is provided with a water supply valve 42 that switches between water discharge and water stoppage, and a float 43 that switches between water discharge and water stoppage by the water supply valve 42 by moving up and down according to fluctuations in the water level in the wash water tank 3.

When the wash water in the wash water tank 3 is discharged to the toilet bowl main body 2, the water level of the wash water drops. As a result, the float 43 descends to open the water supply valve 42, so that water supply from the water supply device 4 to the washing water tank 3 is started. On the other hand, when the water level in the washing water tank 3 rises due to the water supply from the water supply device 4, the float 43 rises as the water level rises and the water supply valve 42 is closed, so that the water supply device 4 moves to the washing water tank 3. Water supply stops. As a result, the water level of the washing water in the washing water tank 3 is maintained at the full water level WL at the time of full water.

The drain valve device 5 is provided above the drain port 32, and by opening or closing the drain port 32, drainage from the wash water tank 3 to the toilet bowl main body 2 is started or stopped. An example of the configuration of the drain valve device 5 will be described with reference to FIG. FIG. 3 is a schematic view showing an example of the configuration of the drain valve device 5.

As shown in FIG. 3, the drain valve device 5 is a direct-acting drain valve device including a drain valve 51 that opens and closes the drain port 32 by moving up and down.

The drain valve device 5 includes a drain port forming member 52 attached to the drain port 32 of the washing water tank 3, and the washing water in the washing water tank 3 is discharged downward from substantially the center of the drain port forming member 52. The water is discharged to the toilet bowl main body 2 through a drainage pipe 52a formed so as to extend. The drainage port forming member 52 is formed with a plurality of communication ports 521 for allowing the washing water on the outside of the drainage valve device 5 to flow into the drainage pipe line 52a.

The drain valve 51 is arranged above the drain pipe 52a and opens or closes the drain pipe 52a (that is, the drain port 32). A valve body 511 that abuts on the valve seat 53 formed at the upper end of the drainage pipe 52a is provided at the lower end of the drain valve 51, and the drain valve side wire member 122 described later is provided at the upper end of the drain valve 51. One end portion 122a of is connected.

Normally, the valve body 511 of the drain valve 51 is in contact with the valve seat 53 of the drainage pipe line 52a, and the drainage pipe line 52a (that is, the drainage port 32) is in a state of being closed by the valve body 511. On the other hand, when the drain valve 51 is pulled up by the drain valve side wire member 122, the valve body 511 is separated from the valve seat 53 and the drain pipe line 52a is opened. As a result, the washing water stored in the washing water tank 3 is discharged to the toilet bowl main body 2, and the washing operation is performed in the toilet bowl main body 2.

As shown in FIG. 3, various related parts for adjusting the timing of starting the valve opening operation of the drain valve 51 in each of the large cleaning mode and the small cleaning mode are inside the drain valve device 5. However, even if these related parts are omitted, the pulling function of the drain valve 51 can be ensured at a minimum, and thus the description thereof is omitted here.

In FIG. 3, the drain valve 51 and the valve body 511 in the state where the valve body 511 is in contact with the valve seat 53 and is in the valve closing position P0 are shown by solid lines, and the valve body 511 rises to the maximum valve opening position P1 in the small cleaning mode. The drain valve 51 and the valve body 511 in the state where the valve body 511 is raised to the maximum valve opening position P2 in the above-mentioned state and the large cleaning mode are shown by chain lines, respectively. In the state when the valve is opened in the large cleaning mode, the valve body 511 of the drain valve 51 is pulled up from the valve closing position P0 to the maximum valve opening position P2 so that the drain port 32 is opened. At this time, the rising height (stroke) H of the valve body 511 with respect to the valve seat 53 becomes the maximum height (maximum stroke) H1 higher than the pulling height H2 in the small washing mode (H1> H2), and the washing water tank. A relatively large amount of washing water is supplied from the inside of the toilet bowl to the toilet bowl main body 2, and the toilet bowl washing in the large washing mode is started.

On the other hand, in the state at the time of valve opening in the small cleaning mode, the valve body 511 of the drain valve 51 is pulled up from the valve closing position P0 to the maximum valve opening position P1 in the small cleaning mode, which is lower than the maximum valve opening position P2 in the large cleaning mode. The drainage port 32 is opened. At this time, the rising height (stroke) H of the valve body 511 with respect to the valve seat 53 is a height H2 lower than the maximum stroke H1 in the large cleaning mode, which is smaller than the amount of cleaning water from the inside of the cleaning water tank 3 in the large cleaning mode. The amount of washing water is supplied to the toilet bowl main body 2, and the toilet bowl washing in the small washing mode is started.

After the drainage operation in the large wash mode or the small wash mode is started, the drain valve 51 descends as the water level in the wash water tank 3 drops. Then, when the drain valve 51 descends to the valve closing position P0, which is the standby position (start position), the valve body 511 comes into contact with the valve seat 53, the drain port 32 is closed, and the drain operation ends. After that, the washing water in the washing water tank 3 is stored up to a predetermined full water level WL by the water supply from the water supply device 4.

The drive unit 6 electrically drives the drain valve 51 to start the drainage operation from the washing water tank 3 to the toilet body 2 as described above.

<3. Drive unit configuration>
Next, an example of the configuration of the drive unit 6 will be specifically described with reference to FIG. FIG. 4 is a schematic view showing an example of the configuration of the drive unit 6.

As shown in FIG. 4, the drive unit 6 includes a drive unit 11 operated by electric power, an elongated drain valve side operating member 12 connected to the drain valve 51, and an elongated drive connected to the drive unit 11. A portion-side operating member 13 and a connecting portion 14 for connecting the drain valve-side operating member 12 and the driving portion-side operating member 13 are provided.

The drain valve side operating member 12 includes a drain valve side tube member 121 and a drain valve side wire member 122 slidably inserted into the drain valve side tube member 121. Both ends of the drain valve side wire member 122 project from both ends of the drain valve side tube member 121, one end 122a is connected to the drain valve 51, and the other end 122b is a pulley 60 described later of the connection portion 14. Connected to. Further, of both ends of the drain valve side tube member 121, one end 121a is fixed to the upper part of the drain valve device 5, and the other end 121b is fixed to the casing 70 of the connection portion 14.

The drive unit side operation member 13 includes a drive unit side tube member 131 and a drive unit side wire member 132 slidably inserted into the drive unit side tube member 131. Both ends of the drive unit side wire member 132 project from both ends of the drive unit side tube member 131, one end 132a is connected to an actuator 111 described later of the drive unit 11, and the other end 132b is a connection portion 14. It is connected to the pulley 60 of. Further, of both ends of the drive unit side tube member 131, one end 131 a is fixed to the casing 112 of the drive 11, and the other end 131 b is fixed to the casing 70 of the connection 14.

The drive unit 11 includes an actuator 111 and a casing unit 112 that houses the actuator 111. The actuator 111 includes a drive source such as a motor operated by electric power, a plurality of gears connected to the drive source, and the like.

The actuator 111 is connected to an electric wire extending from a control device 150 (see FIG. 1) included in the flush toilet device 1, and power is supplied from the control device 150 to the actuator 111 via the electric wire. For example, when the operation button 101 of the instruction device 100 shown in FIG. 1 is pressed by the user, or when a motion sensor (not shown) detects the user, the instruction device 100 or the motion sensor (not shown) is a control device. A predetermined signal is transmitted to the 150. Then, when the control device 150 receives this signal, it supplies electric power to the actuator 111 to rotate the motor of the actuator 111.

One end 132a of the drive unit side wire member 132 is connected to the actuator 111. When one end 132a of the drive unit side wire member 132 is pulled by the actuator 111, the pulley 60 connected to the other end portion 132b of the drive unit side wire member 132 rotates about the vertical axis Ax and becomes the pulley 60. The other end 122b of the connected drain valve side wire member 122 is pulled. By pulling the other end 122b of the drain valve side wire member 122, the drain valve 51 connected to the one end 122a of the drain valve side wire member 122 rises and the drainage operation is started.

On the other hand, when the state in which the drive unit side wire member 132 is pulled by the actuator 111 is released, the drive unit side wire member 132, the pulley 60, and the drain valve side wire member 122 return to their original positions, and the drain valve 51 lowers. Then, the drainage operation is completed.

Here, as shown in FIG. 4, a part of the drain valve side wire member 122 is in a state of being immersed in the washing water in the washing water tank 3. Therefore, the cleaning water adhering to the drain valve side wire member 122 may enter the gap between the drain valve side wire member 122 and the drain valve side tube member 121 as the drain valve side wire member 122 slides. .. Since the gap between the drain valve side wire member 122 and the drain valve side tube member 121 is very narrow, the washing water that has entered the gap may rise along the drain valve side operating member 12 due to the capillary phenomenon.

In the conventional drive unit, since the drain valve and the drive unit are connected by one operation member, the washing water that has raised the operation member due to the capillary phenomenon reaches the drive unit, and the motor or the like built in the drive unit or the like. There was a risk of damaging the electrical parts of.

Therefore, in the drive unit 6 according to the present embodiment, the operation member connecting the drain valve 51 and the drive unit 11 is physically divided into the drain valve side operation member 12 and the drive unit side operation member 13, and the other end portion 122b , 132b are separated from each other and connected by the connecting portion 14. As a result, even if the washing water in the washing water tank 3 rises along the drain valve side operating member 12 due to the capillary phenomenon, the washing water is not transmitted from the drain valve side wire member 122 to the drive unit side wire member 132. Can be. Therefore, according to the drive unit 6 according to one aspect of the embodiment, it is possible to prevent the wash water in the wash water tank 3 from entering the drive unit 11 through the operating member, and the inside of the drive unit 11 can be prevented. It is possible to prevent failures of electrical parts such as the actuator 111 that is arranged.

The washing water that raises the drain valve side operating member 12 due to the capillary phenomenon may reach the connecting portion 14. Therefore, it is preferable that the connecting portion 14 is arranged inside the washing water tank 3. By arranging the connecting portion 14 in the washing water tank 3 in this way, the washing water that has risen from the drain valve side operating member 12 due to the capillary phenomenon reaches the connecting portion 14 and leaks from the connecting portion 14. Even in this case, the leaked washing water returns to the inside of the washing water tank 3, so that the toilet room is not likely to get wet with the washing water.

Further, the connecting portion 14 is arranged at a position higher than the full water level WL inside the washing water tank 3 so that the connecting portion 14 and the driving unit side operating member 13 are not immersed in the washing water stored in the washing water tank 3. It is preferable to be done. The connection portion 14 according to the present embodiment is arranged above the drain valve device 5. Specifically, the connecting portion 14 includes a mounting portion 80 for mounting the connecting portion 14 on the upper part of the drain valve device 5. The mounting portion 80 is provided with a plurality of holding portions 81 for holding the middle portion of the drain valve side tube member 121.

Further, among the drive units 6, the drive unit 11 is preferably arranged outside the washing water tank 3. By arranging the drive unit 11 outside the washing water tank 3, it is possible to suppress the increase in size of the washing water tank 3. An insertion hole 33 for taking out the drive unit side wire member 132 to the outside is formed in the upper part of the wall surface on the rear side of the washing water tank 3.

FIG. 4 shows an example in which the drive unit 11 is attached to the wall surface on the rear side of the wash water tank 3, but the attachment position of the drive unit 11 is not necessarily the wall surface on the rear side of the wash water tank 3. I don't need it.

Next, a specific configuration of the connecting portion 14 will be described with reference to FIG. FIG. 5 is an exploded perspective view of the drive unit 6.

As shown in FIG. 5, the connecting portion 14 includes a pulley 60 and a casing portion 70 that accommodates the pulley 60. Further, the connecting portion 14 includes a mounting portion 80 to the drain valve device 5 and a shaft portion 90 for rotatably holding the pulley 60 in the casing portion 70.

The pulley 60 has a first groove portion 61a over which the drain valve side wire member 122 is bridged, and a first fixing portion 61b for fixing the other end portion 122b of the drain valve side wire member 122. Further, the pulley 60 has a second groove portion 62a over which the drive portion side wire member 132 is bridged, and a second fixing portion 62b for fixing the other end portion 132b of the drive portion side wire member 132.

By repeating the operation of pulling the drive unit side operation member 13 and the operation of returning it to the original position, the drain valve side operation member 12 and the drive unit side operation member 13 may be bent or broken around the connection unit 14. Therefore, the drain valve side operation member 12 and the drive unit side operation member 13 are connected by a pulley 60. According to this configuration, when the drain valve side operation member 12 and the drive unit side operation member 13 move with the operation of pulling or returning the drive unit side operation member 13, the pulley 60 causes the drain valve side wire member. By guiding the 122 and the drive unit side wire member 132, it is possible to prevent them from being bent or broken.

Further, the drain valve side wire member 122 is bridged to the first groove portion 61a, and the drive portion side wire member 132 is bridged to the second groove portion 62a, so that the drain valve side wire member 122 and the drive portion side wire member 132 are bridged. Since the contact with the water is prevented, it is possible to prevent the washing water from being transmitted from the drain valve side operating member 12 to the driving unit side operating member 13 through the contact portion.

The configuration of the pulley 60 will be specifically described with reference to FIGS. 6A and 6B. FIG. 6A is a schematic view of the pulley 60 viewed from the horizontal direction, and FIG. 6B is a schematic view of the pulley 60 viewed from below.

As shown in FIGS. 5, 6A and 6B, the pulley 60 includes a first pulley portion 61, a second pulley portion 62, and a shaft portion 63. The first pulley portion 61 has a first groove portion 61a and a first fixing portion 61b. The second pulley portion 62 is arranged at a distance from the first pulley portion 61, and has a second groove portion 62a and a second fixing portion 62b. The shaft portion 63 connects the first pulley portion 61 and the second pulley portion 62 and rotates them integrally.

In this way, the first pulley portion 61 having the first groove portion 61a and the first fixing portion 61b and the second pulley portion 62 having the second groove portion 62a and the second fixing portion 62b are separated and separated from each other. It is possible to more reliably prevent the transmission of the washing water from the drain valve side wire member 122 to the drive unit side wire member 132.

The first pulley portion 61 and the second pulley portion 62 have a plan view fan shape. Specifically, the first pulley portion 61 and the second pulley portion 62 according to the present embodiment have a fan shape having a central angle of 90 degrees, and the first groove portion 61a is formed in each of the arcuate portions in the fan shape. And the second groove 62a is formed.

Further, the first pulley portion 61 and the second pulley portion 62 have an extending portion in which the end portion of the arc in the fan shape extends along the arc, and the first fixing portion is provided in each of the extending portions. A 61b and a second fixing portion 62b are formed. Specifically, the first fixing portion 61b is formed in an extending portion extending one end of an arc on one side (left side in FIG. 6B) of the first pulley portion 61, and the second fixing portion 62b is formed. , The end of the second pulley portion 62 on the other side of the arc (on the right side in FIG. 6B) is formed in the extending portion.

In this way, by providing the first fixing portion 61b on one end side of the arc in the fan shape and providing the second fixing portion 62b on the other end side of the arc, the drain valve side wire member 122 and the drive portion side wire member 132 can be formed. Will be bridged to the pulley 60 in a state where they overlap each other in a plan view. As a result, a large area where the drain valve side operation member 12 and the drive unit side operation member 13 are guided by the pulley 60 can be secured, so that the drain valve side operation member 12 and the drive unit side operation member 13 are bent or bent. Etc. can be made less likely to occur.

Further, the first pulley portion 61 and the second pulley portion 62 are arranged side by side in the vertical direction, and the first pulley portion 61 is arranged below the second pulley portion 62.

By arranging the first pulley portion 61 below the second pulley portion 62 in this way, it is possible to prevent the transmission of the washing water from the drain valve side wire member 122 to the drive unit side wire member 132. That is, it is possible to prevent the washing water that has risen along the drain valve side wire member 122 from falling due to gravity and adhering to the drive unit side wire member 132. Further, by arranging the first pulley portion 61 and the second pulley portion 62 side by side in the vertical direction, the height dimension of the connecting portion 14 can be suppressed to be small, so that the size of the washing water tank 3 can be prevented from becoming large. Can be done.

Further, the first pulley portion 61 has a plurality of through holes 61c penetrating in the vertical direction. As a result, even if the washing water that has risen on the drain valve side operating member 12 due to the capillary phenomenon reaches the first pulley portion 61, the first pulley is formed from the arc portion over which the drain valve side wire member 122 is bridged. The washing water toward the central portion where the shaft portion 63 connecting the portion 61 and the second pulley portion 62 is arranged can be released from the through hole 61c. Therefore, since the transmission of the cleaning water from the first pulley portion 61 to the shaft portion 63 is prevented, it is possible to more reliably prevent the transmission of the cleaning water from the drain valve side wire member 122 to the drive unit side wire member 132. it can. Here, although it is decided that a plurality of through holes 61c are formed in the first pulley portion 61, the number of through holes 61c formed in the first pulley portion 61 may be one.
