  However, since a part of the operation member is immersed in the cleaning water in the tank, there is a risk that the cleaning water in the tank may enter the drive unit through the operation member due to capillary action, and may damage the internal electrical components. is there.

  An embodiment of the disclosure aims to provide a flush toilet device and a drain valve drive unit that can prevent wash water in a wash water tank from entering a drive unit through an operation member.

  A flush toilet apparatus according to an aspect of the embodiment includes a toilet body, a wash water tank that stores wash water to be supplied to the toilet body, and is disposed in the wash water tank so as to move up and down. A drain valve device comprising a drain valve for opening and closing the drain port of the wash water tank; and a drive unit for driving the drain valve provided in the drain valve device, wherein the drive unit is driven by electric power; and An elongated drain valve side operation member having one end connected to the drain valve, an elongated drive unit side operation member having one end connected to the drive unit, the drain valve side operation member, and the drive unit side A connection portion for connecting the drain valve side operation member and the drive unit side operation member in a state where the other end portions of the operation member are separated from each other is provided.

  The operation member that connects the drain valve and the drive unit is physically divided into a drain valve side operation member and a drive unit side operation member, and the connection unit is connected with the ends separated from each other. Thereby, even if the cleaning water in the cleaning water tank rises along the drain valve side operation member due to capillary action, the cleaning water is prevented from being transmitted from the drain valve side operation member to the drive unit side operation member. it can. Therefore, according to the flush toilet apparatus according to one aspect of the embodiment, the wash water in the wash water tank can be prevented from entering the drive unit through the operation member, and is disposed inside the drive unit. It is possible to prevent failure of electrical components.

  In addition, the connection part includes a pulley having a first groove part over which the drain valve side operation member is bridged and a second groove part over which the drive part side operation member is bridged.

  By repeating the operation of pulling the operation member and the operation of returning the operation member, the operation member may be bent or bent around the connection 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 in accordance with the operation of pulling the operation member or the operation of returning the original, the pulley moves the drain valve side operation member and the drive unit side operation member. By guiding, it is possible to make it difficult to bend or fold them. Further, the drain valve side operation member is bridged over the first groove part, and the drive part side operation member is bridged over the second groove part, thereby preventing contact between the drain valve side operation member and the drive part side operation member. For this reason, it is possible to prevent the cleaning water from being transmitted from the drain valve side operation member to the drive unit side operation member via the contact portion.

  The pulley includes a first pulley part having the first groove part, a second pulley part having the second groove part, the first pulley part being disposed at a distance from the first pulley part, and the first pulley part and the first pulley part. And a shaft portion for integrally rotating 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 to be spaced apart from each other, washing water from the drain valve side operation member to the drive portion side operation member is arranged. Transmission can be prevented more reliably.

  The connecting portion includes a casing portion that houses the pulley, and the casing portion includes a partition plate between the first pulley portion and the second pulley portion.

  By providing the partition plate between the first pulley portion and the second pulley portion, it is possible to more reliably prevent the cleaning water from being transmitted from the drain valve side operation member to the drive unit side operation member.

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

  By disposing the first pulley portion below the second pulley portion, it is possible to prevent the cleaning water from being transmitted from the drain valve side operation member to the drive unit side operation member. In other words, it is possible to prevent a situation in which the cleaning water rising through the drain valve side operation member falls due to gravity and adheres to the drive unit side operation member. Moreover, since the height dimension of a connection part can be restrained small by arrange | positioning a 1st pulley part and a 2nd pulley part along with an up-down direction, the enlargement of a washing water tank can be prevented.

  The first pulley portion has one or a plurality of through holes penetrating in the vertical direction.

  Even if the cleaning water that has lifted the drain valve side operation member due to the capillary phenomenon reaches the first pulley portion, the cleaning water can escape from the through hole. Therefore, it is possible to more reliably prevent the cleaning water from being transmitted from the drain valve side operation member to the drive unit side operation member.

  The pulley has a fan shape in plan view, and has a first fixing portion for fixing the other end portion of the drain valve side operation member on one end side of the arc in the fan shape, and the other end side of the arc. And a second fixing part for fixing the other end of the driving part side operation member.

  A state in which the drain valve side operation member and the drive unit side operation member overlap each other in plan view 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. It will be over the pulley. As a result, the drain valve side operation member and the drive unit side operation member can be secured in a large area so that the drain valve side operation member and the drive unit side operation member are bent or bent more. Can be difficult.

  The connecting portion may be disposed inside the cleaning water tank, and the driving unit may be disposed outside the cleaning water tank.

  By arranging the connection part inside the washing water tank, even if the washing water that has risen the drain valve side operation member due to capillary action reaches the connection part and leaks from the connection part, Since the wash water returns to the inside of the wash water tank, there is no possibility that the toilet room gets wet with the wash water. Moreover, the enlargement of the washing water tank can be suppressed by arranging the drive unit outside 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 operation member. .

  Hereinafter, embodiments of a flush toilet apparatus and a drain valve drive unit disclosed in the present application will be described in detail with reference to the accompanying drawings. In addition, this invention is not limited by embodiment shown below.

<1. Overall configuration of flush toilet device>
First, the whole structure of the flush toilet apparatus which concerns on this embodiment is demonstrated with reference to FIG. FIG. 1 is an overall perspective view showing an example of the configuration of a flush toilet apparatus.

  In the present specification, the vertically upward direction is described as “upward” and the vertically downward direction is described as “downward”. Further, when viewed from the user facing the toilet main body 2, the front side of the toilet main body 2 is described as “front”, the rear side as “rear”, the right side as “right side”, and the left side as “left side”.

  As shown in FIG. 1, the flush toilet apparatus 1 includes a toilet main body 2 and a flush water tank 3. The toilet body 2 is, for example, a Western-style toilet made of ceramics, and includes a bowl portion 21 and a drain trap pipe 22 communicating with a lower portion of the bowl portion 21. The bowl portion 21 is formed with a spout 23 for discharging wash water supplied from a water conduit (not shown) formed inside the toilet body 2, and the wash water discharged from the spout 23 is The bowl portion 21 is lowered while turning to wash the bowl portion 21. The drain trap pipe 22 is provided with an opening on one end side below the reservoir surface W0 of the cleaning water stored in the bowl portion 21, and the opening on the other end side is provided via a drain socket (not shown). Connected to a discharge pipe (not shown) under the floor.

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

<2. Internal structure of washing water tank>
Next, the internal configuration of the washing water tank 3 will be described with reference to FIG. FIG. 2 is a schematic diagram illustrating an example of an internal configuration of the cleaning water tank 3.

  As shown in FIG. 2, a drain port 32 communicating with a water conduit (not shown) of the toilet body 2 is formed at the bottom 31 of the flush water tank 3, and the flush water in the flush water tank 3 is The drainage port 32 is supplied to a water conduit (not shown) of the toilet body 2.

  Inside the washing 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 cleaning water into the cleaning water tank 3. Specifically, the water supply device 4 includes a water supply pipe 41 connected to an external water supply source (not shown), and a spout of cleaning water that is attached to the upper end portion of the water supply pipe 41 and is supplied from the water supply pipe 41. A water supply valve 42 for switching between water discharge and water stop, and a float 43 for switching water discharge and water stop by the water supply valve 42 by moving up and down according to the fluctuation of the water level in the washing water tank 3.

  When the wash water in the wash water tank 3 is discharged to the toilet body 2, the wash water level is lowered. Thereby, the float 43 descend | falls and the water supply valve | bulb 42 is open | released, and the water supply from the water supply apparatus 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 closes the water supply valve 42, so that the water supply device 4 transfers to the washing water tank 3. Water supply stops. Thereby, the water level of the cleaning water in the cleaning water tank 3 is maintained at the full water level WL when the water is full.

  The drain valve device 5 is provided in the upper part of the drain port 32, and starts or stops draining from the flush water tank 3 to the toilet body 2 by opening or closing the drain port 32. An example of the configuration of the drain valve device 5 will be described with reference to FIG. FIG. 3 is a schematic diagram illustrating 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 having therein 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 cleaning water tank 3, and the cleaning water in the cleaning water tank 3 flows downward from a substantially central portion of the drain port forming member 52. It is discharged to the toilet main body 2 through the drain pipe 52a formed to extend. The drain port forming member 52 is formed with a plurality of communication ports 521 for allowing the washing water outside the drain valve device 5 to flow into the drain pipe 52a.

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

  Normally, the valve body 511 of the drain valve 51 is in contact with the valve seat 53 of the drain pipe 52 a, and the drain pipe 52 a (that is, the drain port 32) is 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 52a is opened. As a result, the wash water stored in the wash water tank 3 is discharged to the toilet body 2 and the toilet body 2 performs a washing operation.

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

  In FIG. 3, the drain valve 51 and the valve body 511 in a state where the valve body 511 is in contact with the valve seat 53 and in the valve closing position P0 are indicated by solid lines, and the valve body 511 is raised to the highest valve opening position P1 in the small cleaning mode. The drain valve 51 and the valve body 511 in a state in which the valve body 511 is raised to the highest valve opening position P2 in the large washing mode are indicated by chain lines. In the state when the valve is opened in the large washing 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, and 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 lifting height H2 in the small cleaning mode (H1> H2), and the cleaning water tank A relatively large amount of cleaning water is supplied to the toilet body 2 from within 3, and toilet cleaning in the large cleaning mode is started.

  On the other hand, in the state when the valve is opened in the small washing mode, the valve body 511 of the drain valve 51 is lifted from the valve closing position P0 to the highest valve opening position P1 in the small washing mode lower than the highest valve opening position P2 in the large washing mode. 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 is a height H2 lower than the maximum stroke H1 in the large cleaning mode, and is smaller than the amount of cleaning water in the large cleaning mode from the cleaning water tank 3. Washing water of the amount of washing water is supplied to the toilet bowl main body 2, and toilet flushing in the small washing mode is started.

  After the drainage operation in the large washing mode or the small washing mode is started, the drainage valve 51 descends as the water level in the washing water tank 3 decreases. When the drain valve 51 is lowered to the valve closing position P0 that 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 draining operation is finished. Thereafter, the wash water in the wash water tank 3 is stored by a water supply from the water supply device 4 to a predetermined full water level WL.

  The drive unit 6 starts the drain operation from the washing water tank 3 to the toilet body 2 by driving the drain valve 51 electrically.

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

  As shown in FIG. 4, the drive unit 6 includes a drive unit 11 that operates by electric power, an elongated drain valve side operation member 12 connected to the drain valve 51, and an elongated drive connected to the drive unit 11. A part-side operation member 13 and a connection part 14 that connects the drain valve-side operation member 12 and the drive part-side operation member 13 are provided.

  The drain valve side operation 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 end portions of the drain valve side wire member 122 protrude from both end portions of the drain valve side tube member 121, one end portion 122 a is connected to the drain valve 51, and the other end portion 122 b is a pulley 60 described later of the connection portion 14. Connected to. Further, of the both end portions of the drain valve side tube member 121, one end portion 121 a is fixed to the upper portion of the drain valve device 5, and the other end portion 121 b is fixed to the casing portion 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 end portions of the drive unit side wire member 132 protrude from both end portions of the drive unit side tube member 131, one end portion 132 a is connected to an actuator 111 described later of the drive unit 11, and the other end portion 132 b is connected to the connection portion 14. Connected to the pulley 60. Of the both ends of the drive unit side tube member 131, one end 131 a is fixed to the casing unit 112 of the drive unit 11, and the other end 131 b is fixed to the casing unit 70 of the connection unit 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 that is operated by electric power, and a plurality of gears connected to the drive source.

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

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

  On the other hand, when the state where the actuator 111 wire member 132 is pulled by the actuator 111 is released, the driver wire member 132, the pulley 60, and the drain valve side wire member 122 return to their original positions, and the drain valve 51 is lowered. Then, the draining operation is completed.

  Here, as shown in FIG. 4, the drain valve side wire member 122 is partially immersed in the cleaning water in the cleaning water tank 3. For this reason, the washing 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 wash water that has entered the gap may rise along the drain valve side operation member 12 due to capillary action.

  In the conventional drive unit, since the drain valve and the drive unit are connected by a single operation member, the cleaning water that has lifted the operation member by capillary action reaches the drive unit, and the motor built in the drive unit, etc. There was a risk of failure of the electrical components.

  Therefore, the drive unit 6 according to the present embodiment physically separates the operation member that connects the drain valve 51 and the drive unit 11 into the drain valve side operation member 12 and the drive unit side operation member 13, and the other end 122b. , 132 b are separated from each other by the connecting portion 14. As a result, even if the cleaning water in the cleaning water tank 3 rises through the drain valve side operation member 12 due to capillary action, the cleaning 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 cleaning water in the cleaning water tank 3 from entering the driving unit 11 through the operation member, and inside the driving unit 11. It is possible to prevent failure of electrical components such as the actuator 111 arranged.

  Note that the washing water that moves up the drain valve side operation member 12 by capillary action may reach the connection portion 14. For this reason, it is preferable to arrange the connecting portion 14 inside the cleaning water tank 3. Thus, by arranging the connection part 14 in the cleaning water tank 3, the cleaning water that has risen the drain valve side operation member 12 by capillary action reaches the connection part 14 and leaks from the connection part 14. Even in this case, since the leaked washing water returns to the inside of the washing water tank 3, there is no possibility that the toilet room gets wet with the washing water.

  Further, the connecting portion 14 is disposed at a position higher than the full water level WL inside the cleaning water tank 3 so that the connecting portion 14 and the drive unit side operation member 13 are not immersed in the cleaning water stored in the cleaning water tank 3. It is preferred that The connection portion 14 according to the present embodiment is disposed on the upper portion of the drain valve device 5. Specifically, the connection part 14 includes an attachment part 80 for attaching the connection part 14 to the upper part of the drain valve device 5. The attachment portion 80 is provided with a plurality of holding portions 81 for holding the midway portion of the drain valve side tube member 121.

  Further, in the drive unit 6, the drive unit 11 is preferably arranged outside the cleaning water tank 3. By disposing the drive unit 11 outside the cleaning water tank 3, the size of the cleaning water tank 3 can be suppressed. An insertion hole 33 is formed in the upper part of the rear wall of the cleaning water tank 3 for taking out the drive unit side wire member 132 to the outside.

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

  Next, a specific configuration of the connection unit 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 houses the pulley 60. Moreover, the connection part 14 is provided with the attaching part 80 to the drain valve apparatus 5, and the axial part 90 for hold | maintaining the pulley 60 rotatably in the casing part 70. As shown in FIG.

  The pulley 60 includes a first groove portion 61 a that spans the drain valve side wire member 122 and a first fixing portion 61 b that fixes the other end portion 122 b of the drain valve side wire member 122. In addition, the pulley 60 includes a second groove portion 62 a around which the driving unit side wire member 132 is bridged, and a second fixing unit 62 b that fixes the other end portion 132 b of the driving unit side wire member 132.

  By repeating the operation of pulling the drive unit side operation member 13 and the operation of returning the drive unit side operation member 13, the drain valve side operation member 12 and the drive unit side operation member 13 may be bent or bent 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 in accordance with an operation of pulling or returning the drive unit side operation member 13, the pulley 60 is connected to the drain valve side wire member. By guiding 122 and the drive part side wire member 132, it is possible to make them less likely to be bent or broken.

  Moreover, the drain valve side wire member 122 and the drive part side wire member 132 are constructed by spanning the drain valve side wire member 122 to the first groove part 61a and spanning the drive part side wire member 132 to the second groove part 62a. Therefore, it is possible to prevent the cleaning water from being transmitted from the drain valve side operation member 12 to the drive unit side operation member 13 through the contact portion.

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

  As shown in FIGS. 5, 6 </ b> A, and 6 </ b> B, 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 disposed 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 together.

  As described above, 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 divided and spaced apart. Accordingly, the cleaning water can be more reliably prevented from being transferred 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 fan shape in plan view. Specifically, the first pulley portion 61 and the second pulley portion 62 according to the present embodiment have a fan shape with a central angle of 90 degrees, and the first groove portions 61a are respectively formed in arc portions of the fan shape. And the 2nd groove part 62a is formed.

  Each of the first pulley portion 61 and the second pulley portion 62 has an extended portion in which an end portion of a circular arc in a fan shape extends along the circular arc, and each of the extended portions has a first fixing portion. 61b and the second fixing portion 62b are formed. Specifically, the first fixing portion 61b is formed in an extending portion obtained by extending an end portion on one side (left side in FIG. 6B) of the arc in the first pulley portion 61, and the second fixing portion 62b is The second pulley portion 62 is formed in an extended portion extending from the other end (right side in FIG. 6B) of the arc.

  Thus, by providing the 1st fixing | fixed part 61b in the one end side of the circular arc in fan shape, and providing the 2nd fixing | fixed part 62b in the other end side of a circular arc, the drain valve side wire member 122 and the drive part side wire member 132 are provided. Are overlaid on the pulley 60 in a state of overlapping each other in plan view. As a result, the drain valve side operation member 12 and the drive unit side operation member 13 can be secured in a wide area 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 more difficult 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.

  Thus, by disposing the first pulley portion 61 below the second pulley portion 62, it is possible to prevent the cleaning water from being transmitted from the drain valve side wire member 122 to the drive unit side wire member 132. In other words, it is possible to prevent a situation in which the cleaning water rising through the drain valve side wire member 122 falls due to gravity and adheres to the drive unit side wire member 132. Moreover, since the height dimension of the connection part 14 can be restrained small by arranging the 1st pulley part 61 and the 2nd pulley part 62 along with an up-down direction, the enlargement of the washing water tank 3 is prevented. Can do.

  The first pulley portion 61 has a plurality of through holes 61c penetrating in the vertical direction.
