Description

The disclosed embodiments relate to a wall-mounted toilet mounting device and a toilet device.

Conventionally, a wall-hung toilet mounting device for fixing a wall-hung flush toilet (hereinafter referred to as a "wall-hung toilet") to a wall is known. The wall-hung toilet mounting device has a frame that is erected in the space behind the wall of the toilet room so as to contact the wall, and the wall-hung toilet is fixed to the frame via the wall of the toilet room.

The wall-hung toilet mounting device has an operation panel on the top of the frame. The operation panel is exposed to the toilet room side through the toilet room wall, and can be operated by the user (see Patent Document 1).

European Patent Application Publication No. 2900877

However, depending on the type of sanitary washing device that is installed on top of a wall-hung toilet, for example, when the toilet lid on the sanitary washing device is opened, there is a risk that the open toilet lid will interfere with the operation panel.

In addition, the wall-hung toilet mounting device described in Patent Document 1 has an adjustment mechanism on the frame for adjusting the height position of the wall-hung toilet. Therefore, according to the wall-hung toilet mounting device described in Patent Document 1, it is possible to avoid interference between the operation panel and the toilet lid by lowering the height of the wall-hung toilet. However, lowering the height of the wall-hung toilet may impair the usability of the flush toilet. Therefore, in order to avoid interference between the operation panel and the toilet lid without changing the height of the wall-hung toilet, it was necessary to prepare multiple dedicated frames of different heights. If multiple frames are present, the height position of the tank attached to the frame may change, which may cause unstable flushing performance, and multiple pipes must be prepared to connect the tank device and the wall-hung toilet, which may make the installation of the wall-hung toilet complicated.

One aspect of the embodiment has been made in consideration of the above, and aims to provide a wall-hung toilet mounting device and toilet device that can easily avoid interference between the toilet cover and an operation panel attached to a wall located on the rear side of the wall-hung toilet, and that makes it easy to set up the wall-hung toilet accordingly.

The wall-hung toilet mounting device according to one embodiment is arranged in a space behind the wall of a toilet room and fixes a wall-hung toilet to the wall, and includes a frame erected in the space behind the wall, a tank supported by the frame, and a tank device including an operation panel provided on the front side of the tank and exposed to the toilet room through the wall, and supplies water stored in the tank to the wall-hung toilet in response to an operation on the operation panel. The frame extends in the vertical direction and includes a plurality of support columns supporting the tank at a position higher than the wall-hung toilet, and a beam section connecting the support columns to each other at a position lower than the tank and to which the rear end of the wall-hung toilet is fixed through the wall, and the support columns include a height adjustment section for adjusting the vertical length of the support columns between the portion to which the tank is fixed and the portion to which the beam section is fixed.

For example, a sanitary washing device is known in which the hinge position of the toilet lid is moved rearward from the existing position in order to improve the sense of unity with the toilet bowl. The toilet lid of this type of sanitary washing device is formed larger than the existing toilet lid by moving the hinge position rearward, so it is likely to interfere with the operation panel located on the back of the wall-hung toilet. In contrast, the wall-hung toilet mounting device according to the embodiment is provided with a height adjustment part that adjusts the vertical length of the support part between the part where the tank is fixed and the part where the beam part is fixed. This makes it possible to adjust the height position of the operation panel located on the front side of the tank without changing the height position of the wall-hung toilet. Therefore, with the wall-hung toilet mounting device according to the embodiment, it is possible to avoid interference between the operation panel located on the wall on the back side of the wall-hung toilet and the toilet lid without impairing the usability of the wall-hung toilet.

In addition, in the wall-mounted toilet mounting device described above, the support portion includes an upper support member to which the tank is fixed and a lower support member to which the beam portion is fixed, and the height adjustment portion is a connection portion between the upper support member and the lower support member, and adjusts the height position of the upper support member relative to the lower support member while the upper support member and the lower support member are connected.

For example, it is possible to adjust the height of the support part by replacing it with an extension part or an upper support part of a different height, but this is complicated because the upper support part must be removed from the lower support part. In contrast, the wall-hung toilet mounting device according to the embodiment makes it easy to adjust the height of the support part while the upper support part and the lower support part are still connected. Also, there is no need to prepare an extension part separately, which reduces waste of parts.

The wall-hung toilet mounting device described above also includes a water supply pipe that connects the tank and the wall-hung toilet, and the water supply pipe includes a length adjustment section that can change the flow path length from the tank to the wall-hung toilet.

Adjusting the length of the support pole changes the distance from the tank to the wall-hung toilet. The wall-hung toilet mounting device according to the embodiment is equipped with a water supply pipe with an adjustable flow path length, so there is no need to replace the water supply pipe even when the length of the support pole is adjusted. This simplifies the work involved in adjusting the length of the support pole.

In addition, in the wall-hung toilet mounting device described above, the tank is equipped with a drainage volume adjustment section that adjusts the drainage volume.

When the tank's height position changes, the force of the water discharged from the tank changes due to a change in potential energy. As a result, there is a risk that proper flushing operation will not be performed. In contrast, the wall-hung toilet mounting device according to the embodiment is equipped with a drainage volume adjustment section in the tank, which allows the drainage volume to be adjusted according to the tank's height position, allowing proper flushing operation to be performed regardless of the tank's height position.

The wall-hung toilet mounting device described above includes a sanitary washing device that is installed on the top surface of the wall-hung toilet, a connection hose that connects the tank and the sanitary washing device, and a guide tube through which the connection hose is inserted, the connection hose having a length that is sufficient to connect the tank, which is supported at the highest position by the support column, to the sanitary washing device or a length that is longer than the required length, and the guide tube has a storage space for storing the excess portion of the connection hose.

By providing a connection hose with a length that includes a surplus length longer than necessary so that the tank supported at the highest position can be connected to the sanitary washing device at a length that allows connection or at multiple heights, the same connection hose can be used regardless of the height of the tank. Also, for example, when adjusting the height of the tank, the surplus length of the connection hose can be prevented from getting in the way of the work. In addition, since the surplus length of the connection hose can be stored in the space behind the wall, a connection hose that is longer than the length required to connect the tank and the sanitary washing device can be provided, making it easy to adjust the height of the tank and connect it to the sanitary washing device.

In addition, in the wall-hung toilet mounting device described above, the storage space is provided in the space behind the wall.

By providing a storage space in the space behind the wall to store the excess length of the connection hose, it is possible to prevent the excess length of the connection hose from protruding into the toilet room and being visible to the user, for example.

In addition, in the wall-hung toilet mounting device described above, the guide pipe has a main pipe line whose one end communicates with the tank and whose other end communicates with the interior of the toilet room, and a branch pipe line that branches off from the middle of the main pipe line to form the storage space.

This configuration allows the excess length of the connection hose to be bent and securely stored, which can effectively prevent stress from being placed on the connection between the connection hose and the sanitary washing device, for example.

In addition, in the wall-hung toilet mounting device described above, the storage space extends in the left-right or up-down direction of the back-of-wall space.

In order to ensure the spaciousness of the toilet room, the space behind the wall tends to be narrow in the depth direction. In contrast, by providing a storage space that expands in the left-right or up-down direction of the space behind the wall, the guide pipe can be appropriately positioned in the space behind the wall that is narrow in the depth direction.

According to one aspect of the embodiment, it is possible to provide a wall-hung toilet mounting device and a toilet device that can easily avoid interference between the toilet cover and an operation panel provided on a wall located on the rear side of the wall-hung toilet, and that facilitates the installation of the wall-hung toilet.

The following describes in detail the embodiments of the wall-hung toilet mounting device and toilet device disclosed in this application with reference to the attached drawings. Note that the present invention is not limited to the embodiments shown below.

<Overall configuration of the toilet device>
First, the overall configuration of the toilet device according to the embodiment will be described with reference to Fig. 1. Fig. 1 is a perspective view of the toilet device according to the embodiment.

For ease of understanding, FIG. 1 illustrates a three-dimensional Cartesian coordinate system including a Z-axis with the positive direction being the vertical upward direction. This Cartesian coordinate system may also be illustrated in other figures. This Cartesian coordinate system defines the positive Y-axis view as the front, the positive X-axis view as the left side, the negative X-axis view as the right side, and the negative Z-axis view as the plane (also called the "top"). For this reason, in the following explanation, the X-axis direction may be referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction (or height direction).

As shown in FIG. 1, the toilet device T according to the embodiment includes a tank frame device 1 (an example of a "wall-hung toilet mounting device"), a wall-hung toilet 2, and a sanitary washing device 3.

(Regarding tank frame devices)
The tank frame device 1 is disposed in a back-wall space of a toilet room. The back-wall space is a space located on the opposite side of a toilet room wall W from the interior of the toilet room in which the flush toilet 2 is disposed. The back-wall space is concealed by the wall W.

The tank frame device 1 comprises a frame 11, a tank device 12, a guide pipe 13, a water supply pipe 14, and a drain pipe 15. The frame 11, the tank 12, the guide pipe 13, the water supply pipe 14, and the drain pipe 15 are arranged in the space behind the wall.

The frame 11 is erected in the space behind the wall and supports the tank device 12 at its upper part. Specifically, the frame 11 includes a plurality of (two in this case) support columns 111 extending vertically upward from the floor surface of the space behind the wall, and a plurality of (three in this case) beam sections 112-114 extending parallel to the floor surface of the space behind the wall and connecting the support columns 111 to each other. The number of support columns 111 and beam sections 112-114 included in the frame 11 is not limited to the above example.

Of the multiple beams 112-114, beam 113 is located lower than the tank device 2 and higher than the drain pipe 15. The rear end of the wall-hung toilet 2 is fixed to beam 113 via wall W. Specifically, multiple mounting holes 115 are formed in beam 113, and a rod-shaped support member (not shown) is inserted into mounting hole 115. The support member protrudes into the toilet room via wall W. Meanwhile, the rear end of the wall-hung toilet 2 is provided with an insertion hole at a position corresponding to the mounting hole 115 of beam 113, and the wall-hung toilet 2 is supported by frame 11 by inserting the support member into the insertion hole.

The tank device 12 includes a tank 120 and an operation panel 122. The tank 120 is connected to an external water supply source (not shown) and stores water supplied from the water supply source. A water supply pipe 14 (described later) is connected to the bottom of the tank 120, and the water stored in the tank 120 is supplied to the wall-hung toilet 2 through the water supply pipe 14. Inside the tank 120, a water supply device that supplies water from the water supply source to the tank 120, a drain valve device that opens and closes the drain outlet of the tank 120 that communicates with the water supply pipe 14, and the like are provided. The flushing operation (water supply and drainage operation) by the water supply device and the drain valve device is started by operating a button on the operation panel 122 (described later). The tank 120 is, for example, a gravity water supply type that uses gravity to supply water to the wall-hung toilet 2.

The tank 120 has an opening 121 formed on the upper front surface thereof, through which maintenance can be performed after installation. During normal use, the opening 121 is covered by an operation panel 122. The operation panel 122 is exposed to the toilet room through an opening in the wall W, and is operated by the user. For example, the operation panel 122 is provided with a large flush button for starting a large flush operation for the water supply device and the drain valve device, and a small flush button for starting a small flush operation.

The guide pipe 13 is a tubular member that guides the connection hose that connects the sanitary washing device 3 and the tank body 12. The connection hose is, for example, a water supply hose for supplying water to the sanitary washing device 3. The guide pipe 13 also protects the connection hose from pests and vermin. The connection hose can be anything other than a water supply hose that connects the sanitary washing device 3 and the tank body 12.

The guide pipe 13 extends in the vertical direction, and is connected at its upper part to the tank body 12, while its lower part communicates with a through hole Wh provided in the lower part of the wall W. A connection hose (not shown) is inserted from the through hole Wh into the guide pipe 13, and is guided by the guide pipe 13 to the internal space of the tank body 12. The connection hose is then connected via a branch fitting to a stopcock provided in the internal space of the tank body 12. The other end of the branch fitting is connected to a hose for supplying water from a water source to the internal space of the tank body 12. The specific configuration of the guide pipe 13 will be described later.

The water supply pipe 14 connects the tank 120 and the wall-hung toilet 2, and supplies the water stored in the tank 120 to the wall-hung toilet 2. The water supply pipe 14 has an extension section 141 that extends vertically and is connected to the lower central part of the tank 120, and a bent section 142 that is bent horizontally from the extension section 141 and connects to a water pipe (not shown) of the wall-hung toilet 2. The specific configuration of the water supply pipe 14 will be described later.

The drain pipe 15 is a tubular member. The drain pipe 15 extends vertically upward from the floor of the back wall space where the drain outlet D is provided, and bends approximately 90 degrees at the height of the drainage flow path (not shown) that opens horizontally on the back surface of the wall-hung toilet body 2, connecting the drain outlet D and the drainage flow path of the wall-hung toilet body 2.

(About wall-hung toilets)
The wall-hung toilet 2 is a wall-hung Western-style toilet that is fixed to the frame 11 via the wall W. The wall-hung toilet 2 is made of ceramic, for example. The wall-hung toilet 2 may be made of resin, or may be formed from a combination of ceramic and resin. The wall-hung toilet 2 is connected to a tank 120 via a water supply pipe 14, and performs a flushing operation using water supplied from the tank 120. The flushing operation refers to the operation of flushing waste received in the bowl of the wall-hung toilet 2 into a drain pipe under the floor.

(About sanitary cleaning equipment)
The sanitary washing device 3 is installed on the upper surface of the wall-hung toilet 2. An example of the configuration of the sanitary washing device 3 will be described with reference to Fig. 2. Fig. 2 is a perspective view of the sanitary washing device 3 according to the embodiment.

As shown in FIG. 2, the sanitary washing device 3 includes a casing 311, a toilet seat 312, and a toilet lid 313. The casing 311 is installed on the rear of the upper surface of the wall-hung toilet 2. The toilet seat 312 and the toilet lid 313 are supported on the casing 311 so as to be rotatable.

A plurality of functional parts are housed inside the casing 311. For example, a heat exchanger unit, a nozzle unit, etc. are housed inside the casing 311. The heat exchanger unit is connected to the tank 120 via a connection hose H (see FIG. 6, etc.) and heats water supplied from the tank 120 via the connection hose H. The water heated by the heat exchanger unit is supplied to the nozzle unit. The nozzle unit includes, for example, a cleaning nozzle and a nozzle motor that moves the cleaning nozzle, and ejects water (warm water) supplied from the heat exchanger unit onto a human body part, etc.

In addition, other functional parts may be provided inside the casing 311. For example, the casing 311 may be provided with a multi-function unit including an electrolytic cell, a deodorizing unit that deodorizes the toilet room, etc. In addition, the casing 311 may be provided with a valve unit, a tank unit, a strainer, a pump unit, etc.

The operation panel 122 is located above the sanitary washing device 3. For this reason, when the toilet lid 313 of the sanitary washing device 3 is opened, there is a possibility that the toilet lid 313 and the operation panel 122 may interfere with each other. For example, in the sanitary washing device 3 according to the embodiment, the hinge position of the toilet lid 313 is moved rearward from the existing position in order to improve the sense of unity with the wall-hung toilet 2, and therefore the dimensions of the toilet lid 313 are relatively large. In such a case, there is a possibility that the operation panel and the toilet lid 313 may interfere with each other.

Therefore, in the tank frame device 1 according to the embodiment, a height adjustment section that adjusts the vertical length of the support section 111 is provided between the portion of the support section 111 of the frame 11 where the tank 120 is fixed and the portion of the support section 113 where the beam section 113 is fixed.

The configuration of the tank frame device 1 will be described in detail below. Figure 3 is a front view of the tank frame device 1 according to the embodiment.

As shown in FIG. 3, the support portion 111 of the frame 11 of the tank frame device 1 includes an upper support member 101, a lower support member 102, and a height adjustment portion 103.

The upper support member 101 and the lower support member 102 are long members extending in the vertical direction. Of these, the upper support member 101 is a support member located above the lower support member 102, and the tank device 12 is fixed to the upper support member 101. The upper support member 101 of one support section 111 and the upper support member 101 of the other support section 111 are connected by a beam section 112. The upper support member 101 is formed in a cylindrical shape, and a height adjustment section 103 (described later) is inserted from an opening 101a at the bottom.

The lower support member 102 is located below the upper support member 101. The lower support member 102 is fixed to the floor surface of the space behind the wall via legs 104 provided at the bottom. The lower support member 102 of one support portion 111 and the lower support member 102 of the other support portion 111 are connected by beams 113 and 114. As described above, the wall-hung toilet 2 is fixed to the beam 113 via the wall W. In addition, the drain pipe 15 is fixed to the beam 114.

The height adjustment section 103 is a connection section between the upper support member 101 and the lower support member 102, and extends upward from the top of the lower support member 102. The height adjustment section 103 is formed to be slightly smaller than the upper support member 101, and is inserted into the upper support member 101 through the opening 101a of the upper support member 101.

The height adjustment unit 103 can adjust the height position of the upper support member 101 relative to the lower support member 102 when the upper support member 101 and the lower support member 102 are connected, in other words, when the height adjustment unit 103 is inserted inside the upper support member 101.

Figure 4 is a perspective view of the height adjustment unit 103 according to the embodiment. As shown in Figure 4, the height adjustment unit 103 is provided with a plurality of first adjustment holes 103a along the vertical direction. Similarly, the upper support member 101 is provided with a plurality of second adjustment holes 101b along the vertical direction. Note that a pair of first adjustment holes 103a may be provided, and multiple pairs of second adjustment holes 101b may be provided.

The height adjustment unit 103 is inserted into the upper support member 101 through an opening 101a provided at the bottom of the upper support member 101. Then, with the height positions of any of the first adjustment holes 103a provided in the height adjustment unit 103 and any of the second adjustment holes 101b provided in the upper support member 101 aligned, a fixing member 105 is inserted through these first adjustment holes 103a and second adjustment holes 101b. This fixes the height position of the upper support member 101 relative to the lower support member 102. The fixing member 105 may be provided on the upper support member 101 or the lower support member 102.

In this way, the support portion 111 of the tank frame device 1 according to the embodiment is provided with a height adjustment portion 103 that adjusts the vertical length of the support portion 111 between the upper support member 101 to which the tank device 12 including the operation panel 122 is fixed, and the lower support member 102 to which the beam portion 113 corresponding to the fixing portion of the wall-hung toilet 2 is fixed.

This allows the height position of the operation panel 122 provided on the front side of the tank 120 to be adjusted without changing the height position of the wall-hung toilet 2. Therefore, with the tank frame device 1 according to the embodiment, it is possible to avoid interference between the operation panel 122 provided on the wall on the rear side of the wall-hung toilet 2 and the toilet lid 313 without impairing the usability of the wall-hung toilet 2.

In addition, the tank frame device 1 according to the embodiment allows the height of the support section 111 to be adjusted while the upper support member 101 and the lower support member 102 are connected, making the work easier than adjusting the height of the support section 111 using, for example, an extension member. In addition, there is no need to prepare an extension member separately, which reduces waste of parts.

Here, an example has been described in which the height adjustment unit 103 is provided at the top of the lower support member 102, but the height adjustment unit 103 may also be provided at the bottom of the upper support member 101. In this case, a plurality of second adjustment holes 101b may be provided in the lower support member 102. Also, here, an example has been described in which the height adjustment unit 103 is inserted inside the upper support member 101, but the upper support member 101 (or the lower support member 102) may also be inserted inside the cylindrically formed height adjustment unit 103.

Next, the configuration of the water supply pipe 14 according to the embodiment will be described with reference to FIG. 5. FIG. 5 is a cross-sectional view of the water supply pipe 14 according to the embodiment.

As shown in FIG. 5, the extension portion 141 of the water supply pipe 14 according to the embodiment is divided into multiple (three in this case) tubular members 143 to 145. The tubular members 143 to 145 are arranged in the following order from above: tubular member 143, tubular member 144, and tubular member 145.

The inner diameter of the tubular members 143 to 145 is the largest for the tubular member 143 located at the highest position, and decreases in the order of tubular member 144, tubular member 145, etc. In other words, the inner diameter of the tubular member located further downstream is smaller. Note that the relationship in size between the inner diameters of the tubular members 143 to 145 is not limited to the above example, and for example, the tubular members 143 and 145 may have the same inner diameter, and the tubular member 144 may have an inner diameter larger or smaller than the tubular members 143 and 145.

A seal member 146 is provided between the tubular members 143 and 144. A seal member 147 is provided between the tubular members 144 and 145. The seal members 146 and 147 are, for example, O-rings. The seal member 146 allows the tubular member 144 to slide up and down relative to the tubular member 143 while maintaining the sealed state between the tubular members 143 and 144. Similarly, the seal member 147 allows the tubular member 145 to slide up and down relative to the tubular member 144 while maintaining the sealed state between the tubular members 144 and 145.

In this way, the water supply pipe 14 is equipped with a length adjustment section (tubular members 143 to 145 and sealing members 146, 147) that allows the flow path length from the tank 120 to the wall-hung toilet 2 to be changed.

Adjusting the length of the support part 111 changes the distance from the tank 120 to the wall-hung toilet 2. The tank frame device 1 according to the embodiment is equipped with a water supply pipe 14 with an adjustable flow path length, so that even if the length of the support part 111 is adjusted, there is no need to replace the water supply pipe 14. In this way, the tank frame device 1 according to the embodiment can simplify the work associated with adjusting the length of the support part 111.

As shown in FIG. 3, the tank 120 is provided with a drainage amount adjustment unit 123 for adjusting the amount of water discharged from the tank 120. The drainage amount adjustment unit 123 is provided, for example, in a drainage valve device in the tank 120. As an example, the drainage valve device has a valve body main shaft extending upward, and is equipped with a drainage valve body that opens and closes the tank's drain port in response to the up and down movement of the valve body main shaft, and a float part that moves up and down in conjunction with the water level in the tank 120. The float part is equipped with a water storage bucket (corresponding to the drainage amount adjustment unit 123) that stores water in the tank 120 and has an adjustment window that can discharge the stored water, and a float that is housed in the water storage bucket and is linked to the water level in the water storage bucket when it descends. The adjustment window can be slid, for example, left and right, to change the open area of the opening formed on the side of the water storage bucket. This makes it possible to adjust the amount of water discharged from the water storage bucket. By adjusting the amount of water discharged from the water storage bucket, the amount of water discharged from the tank 120 can be adjusted.

When the height position of the tank 120 changes, the force of the water discharged from the tank 120 changes due to the change in potential energy. As a result, there is a risk that the washing operation will not be performed properly. In contrast, the tank frame device 1 according to the embodiment is provided with a water discharge amount adjustment section in the tank 120, so that the water discharge amount can be adjusted according to the height position of the tank 120, and therefore, the washing operation can be performed properly regardless of the height position of the tank 120.

Next, the configuration of the guide tube 13 according to the embodiment will be described with reference to Figs. 6 and 7. Figs. 6 and 7 are side views of the guide tube 13 according to the embodiment. Fig. 6 shows the guide tube 13 in a state where the bellows tube is extended, and Fig. 7 shows the guide tube 13 in a state where the bellows tube is contracted. Note that in Figs. 6 and 7, the wall W, frame 11, etc. are omitted.

As shown in Figures 6 and 7, the guide tube 13 according to the embodiment includes a bellows tube 131 as a length adjustment section. The bellows tube 131 is a bellows-shaped piping member that is extendable. One end of the guide tube 13 is fixed to the tank 120, and the other end is fixed to the beam section 114. The bellows tube 131 provided in the middle of the guide tube 13 extends and retracts, allowing the overall length of the guide tube 13 to be changed according to the length of the support section 111.

In this way, even if the length of the support portion 111 is adjusted, there is no need to replace the guide tube 13, so the work associated with adjusting the length of the support portion 111 can be simplified.

The connection hose H that connects the tank 120 and the sanitary washing device 3 has a length that allows it to connect the tank 120 supported at the highest position by the support part 111 to the sanitary washing device 3. Therefore, the same connection hose H can be used regardless of the height of the tank 120.

On the other hand, if the connection hose H is made longer, when the tank 120 is placed at a low position, excess length will be created, and there is a risk that the connection hose H may protrude into the toilet room, interfering with the work of adjusting the height of the tank 120.

In contrast, the guide pipe 13 according to the embodiment has a storage space 132 that stores the excess length of the connection hose H. The storage space 132 is an excess space formed by expanding a part of the internal space of the guide pipe 13. For example, the storage space 132 is provided downstream (toward the wall-hung toilet 2) of the bellows pipe 131 in the space behind the wall. In particular, the storage space 132 is provided near the through hole Wh (see FIG. 1). By providing the storage space 132 near the through hole Wh, the excess length of the connection hose H can be smoothly pulled out or put away.

In this way, by providing the storage space 132 in the guide tube 13, it is possible to prevent the excess length of the connection hose H from getting in the way when adjusting the height of the tank 120. In addition, by providing the storage space 132 in the space behind the wall, it is possible to prevent the excess length of the connection hose H from being visible to the user.

Next, modified examples of the above-mentioned guide tube 13 will be described with reference to Figs. 8 and 9. Fig. 8 is a front view of a guide tube according to a first modified example. Fig. 9 is a side view of a guide tube according to a second modified example.

As shown in FIG. 8, the guide pipe 13A according to the first modified example includes a main pipe 133A and a branch pipe 134A. One end of the main pipe 133A is connected to the tank 120, and the other end is connected to the interior of the toilet room. The bellows pipe 131 described above is provided in the main pipe 133A. The branch pipe 134A branches off from the middle of the main pipe 133A to form the storage space 132. The branch pipe 134A has a constricted portion 135A at the branch point from the main pipe 133A.

In this way, by providing the storage space 132 in the branch pipeline 134A, the excess length of the connection hose H can be curved and securely stored, which can preferably prevent stress from being placed on the connection between the connection hose H and the sanitary washing device 3, for example. Also, a larger amount of excess length of the connection hose H can be stored compared to the guide tube 13 according to the embodiment. Also, the repulsive force (return force) generated by the excess length of the connection hose H being curved and stored in the storage space 132 can prevent the stored excess length of the connection hose H from protruding.

The branch pipe 134A also extends to the side of the main pipe 133A. That is, the storage space 132 extends in the left-right direction of the back-wall space. In order to ensure the spaciousness of the toilet room, the back-wall space is formed narrow in the depth direction (Y-axis direction). By having a storage space 132 extending in the left-right direction of the back-wall space, as in the guide pipe 13A of the first modified example, the guide pipe 13A can be appropriately positioned in the back-wall space that is narrow in the depth direction.

As shown in FIG. 9, the guide pipe 13B according to the second modified example includes a main pipe 133B and a branch pipe 134B. The branch pipe 134B has a constricted portion 135B at the branch point from the main pipe 133B.

The branch pipe 134B in the second modified example extends below the main pipe 133B. In other words, the storage space 132 expands in the vertical direction of the back-of-wall space.

In this way, the storage space 132 may be wider in the vertical direction of the back-of-wall space. In this case, too, the guide tube 13B can be appropriately positioned in the back-of-wall space that is narrow in the depth direction.

As described above, the wall-hung toilet mounting device according to the embodiment (for example, tank frame device 1) is a wall-hung toilet mounting device that is arranged in the back-wall space of a toilet room and fixes a wall-hung toilet (for example, wall-hung toilet 2) to a wall (for example, wall W), and includes a frame (for example, frame 11) erected in the back-wall space, a tank (for example, tank 120) supported by the frame, and an operation panel (for example, operation panel 122) provided on the front side of the tank and exposed to the toilet room through the wall, and the operation panel controls the water stored in the tank to flow through the operation panel. The tank device (for example, tank device 1) supplies water to the wall-hung toilet according to the operation of the tank, the frame extends in the vertical direction and includes a number of support columns (for example, support columns 111) that support the tank at a position higher than the wall-hung toilet, and a beam section (for example, beam section 113) that connects the support columns at a position lower than the tank and to which the rear end of the wall-hung toilet is fixed via the wall, and the support columns include a height adjustment section (for example, height adjustment section 103) that adjusts the vertical length of the support columns between the part where the tank is fixed and the part where the beam sections are fixed.

Therefore, the wall-hung toilet mounting device according to the embodiment can easily avoid interference between the toilet cover and the operation panel mounted on the wall behind the wall-hung toilet, making it easier to set up the wall-hung toilet.

In another embodiment, the frame includes a plurality of support columns (for example, support column 111) that extend in the vertical direction and support the tank at a position higher than the wall-hung toilet, and a beam section (for example, beam section 113) that connects the support columns to each other at a position lower than the tank and to which the rear end of the wall-hung toilet is fixed via the wall. The support columns include a height adjustment section between the part where the tank is fixed and the part where the beam section is fixed, which adjusts the vertical length of the support columns, and the upper support member above the height adjustment section can be replaced. In this way, by replacing the upper support members at multiple heights according to the position of the valve cover, it is possible to prevent interference between the valve cover and the operation button. In addition, by providing the extension section 141 of the water supply pipe 14 and the storage space 132 as in the above embodiment, even when replacing the upper support members at multiple heights according to the position of the valve cover, it is possible to easily set up the wall-hung toilet while preventing interference between the valve cover and the operation button, without having to prepare multiple water supply pipes 14 and connection hoses H.

In addition, in the above other embodiment, instead of a frame with a height adjustment mechanism, multiple types of frames with different heights may be prepared, and the height of the frame may be selected according to the height of the valve cover and the operation button and the usage environment. By providing the extension part 141 of the water supply pipe 14 and the storage space 132 as in the above embodiment to match frames of multiple heights, there is no need to prepare multiple water supply pipes 14 and connection hoses H for each height, and the wall-hung toilet can be easily set up while preventing interference between the valve cover and the operation button. Also, by providing the extension part 141 of the water supply pipe 14 and the storage space 132 as in the above embodiment, the water supply pipe 14 and the connection hose H can be made into a platform, so the cost of the wall-hung toilet mounting device can be reduced.

Further advantages and modifications may readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
