Embodiments of the invention relate to a toilet device and a commode unit.

In recent years, a toilet device and a commode unit have become common.

According to JP-A 2005-290967, a sanitary washing toilet seat, which is placed on a western-style toilet and is freely removed or removable, is described.

However, for the western-style toilet on which the sanitary washing toilet seat described in the JP-A 2005-290967 is placed, the water distribution hose and the power supply cord are directly connected to the sanitary washing toilet seat from outside the western-style toilet. In other words, the water distribution hose and the power supply cord are constantly exposed outside the western-style toilet. Thereby, the design quality of the western-style toilet on which the sanitary washing toilet seat is placed is undesirably poor.

On the other hand, a method may be considered in which a through-hole is provided in the upper surface of the western-style toilet; and the water distribution hose and the power supply cord are connected to the sanitary washing toilet seat through the through-hole. However, in the case where the through-hole is provided in the upper surface of the western-style toilet, when liquid waste enters through the gap between the upper surface of the western-style toilet and the lower surface of the sanitary washing toilet seat, there is a risk that the liquid waste may undesirably enter the interior of the western-style toilet from the through-hole. Because the cleanability of the interior of the western-style toilet is poor, offensive odors may undesirably occur due to the liquid waste undesirably entering the interior of the western-style toilet.

The invention is based on the awareness of such problems and has the object of providing a toilet device and a commode unit that can improve the design quality of the commode and suppress the undesirable occurrence of offensive odors due to the liquid waste undesirably entering the interior of the commode. Furthermore, DE 20 2013 001133 U1, WO 2013/041892 A1, DE 10 2011 118352 A1, JP 2014147445 A, EP 2 325 402 A2, EP 2 192 244 A2 and JP H08 85999 A disclose a toilet device.

According to one embodiment, a toilet device is provided. The toilet device is mounted to a commode. An interior space is provided in the commode. The interior space communicates with a through-hole provided in an upper surface of the commode. The toilet device comprises a fixing member fixable to the commode, packing covering an outer circumference of the fixing member, and a toilet device main unit mounted above the fixing member. An insertion unit is provided in the fixing member. A water supply hose or a power supply cord connected to the toilet device main unit that is insertable through the insertion unit.

A plate (a fixing member) 22 and packing 24 according to one embodiment of the invention will now be described using FIGS. 4 to 7.

As shown in FIG. 4, the toilet device 4 includes, for example, the plate (the fixing member) 22 made of a resin. The plate 22 has a plate configuration having the longitudinal direction in a first direction. For example, the plate 22 has a rectangular configuration. The first direction is, for example, a direction (the lateral direction) orthogonal to the vertical direction (referring to FIG. 1) and the frontward/rearward direction (referring to FIG. 1). A first fixing hole (a fixing unit) 26 is provided in the plate 22. The plate 22 can be fixed to the commode 2 by inserting a bolt 28 through the first fixing hole 26 into a second fixing hole 27 provided in the upper surface of the commode 2 and fastening with a nut. When mounting the toilet device main unit 8 to the commode 2, first, the plate 22 is fixed to the commode 2. The power supply cord 18 and the water supply hose 20 that are connected to the toilet device main unit 8 are inserted through an insertion through-hole (an insertion unit) 30 provided in the plate 22.

A through-hole 32 is provided in the upper surface of the commode 2. The through-hole 32 is provided on the rearward side of the bowl 16. Also, an interior space 34 is provided in the interior of the commode 2 on the rearward side of the bowl 16. The interior space 34 is made continuously with the through-hole 32. That is, the interior space 34 communicates with the through-hole 32. Further, a rear hole 36 is provided in the rear surface of the commode 2. The rear hole 36 is made continuously with the interior space 34.

When mounting the toilet device main unit 8 to the commode 2, first, the plate 22 is fixed to the commode 2. Then, the power supply cord 18 and the water supply hose 20 that are connected to the toilet device main unit 8 are inserted through the insertion through-hole 30 provided in the plate 22.

Thereby, the power supply cord 18 and the water supply hose 20 can be concealed in the interior of the commode 2 through the insertion through-hole 30 and the through-hole 32 of the commode 2. Thereby, the exposure of the power supply cord 18 and the water supply hose 20 outside the commode 2 can be suppressed. Accordingly, the design quality of the commode 2 can be improved.

Subsequently, the toilet device main unit 8 is placed above the plate 22. At this time, a cutaway portion 38 that is provided in the end portion of the plate 22 engages a hook (not shown) provided in the case plate 10. Thereby, the toilet device main unit 8 can be fixed to the plate 22 easily.

As shown in FIG. 5, the toilet device 4 includes, for example, the packing 24 formed of rubber. The packing 24 covers the outer circumference of the lower surface (the surface placed on the upper surface of the commode 2) of the plate 22. Thereby, liquid waste that enters between the upper surface of the commode 2 and the toilet device main unit 8 can be prevented from undesirably entering the interior space 34 of the commode 2 via the through-hole 32. Thereby, the undesirable occurrence of offensive odors from the interior space 34 can be suppressed.

In the state in which the plate 22 is mounted to the commode 2 as shown in FIG. 6, the plate 22 is fixed to the commode 2 so that the insertion through-hole 30 of the plate 22 communicates with the through-hole 32 of the commode 2.

In the longitudinal direction of the plate 22, for example, the insertion through-hole 30 of the plate 22 is provided not less than 15 centimeters (cm) toward the outer side from a center line X of the plate 22. Also, for example, the through-hole 32 of the commode 2 is provided not less than 15 cm toward the outer side from a center line Y of the commode 2. Further, the interior space 34 of the commode 2 is provided toward the outer side from the center line Y of the commode 2. The plate 22 is fixed to the commode 2 so that the center line X and the center line Y are at the same position. Thereby, a large interior space 34 can be ensured in the interior of the commode 2 even in the case where the drain trap (not shown) of the commode 2 is positioned on the center line Y of the commode 2. Also, the power supply cord 18 and the water supply hose 20 can be concealed in the interior of the commode 2 through the insertion through-hole 30 and the through-hole 32 of the commode 2 even in the case where the drain trap of the commode 2 is positioned on the center line Y of the commode 2.

In the longitudinal direction of the plate 22, for example, the first fixing hole 26 of the plate 22 is provided not less than 10 cm toward the outer side from the center line X of the plate 22. Also, for example, the second fixing hole 27 of the commode 2 is provided not less than 10 cm toward the outer side from the center line Y of the commode 2. Thereby, the plate 22 can be easily fixed to the commode 2 by inserting the bolt 28 through the first fixing hole 26 into the second fixing hole 27 provided in the upper surface of the commode 2 and fastening the nut even in the case where the drain trap of the commode 2 is positioned on the center line Y of the commode 2.

In the longitudinal direction of the plate 22, the insertion through-hole 30 is positioned on the outer side of the first fixing hole 26. Thereby, when installing the toilet device 4 on the commode 2, the installer can mount the toilet device main unit 8 above the plate 22 in a state in which viewing is easy with the naked eye. In other words, the toilet device main unit 8 that has good installability for the commode 2 can be provided. Also, because the installer can mount the toilet device main unit 8 above the plate 22 in the state in which viewing is easy with the naked eye, the mistake of causing the power supply cord 18 or the water supply hose 20 to be undesirably pinched between the commode 2 and the toilet device 4 can be suppressed.

As shown in FIG. 7, the toilet device 4 includes a pipe member 40 below the plate 22. The pipe member 40 is a tubular body having a circular columnar configuration and is made of a resin. For example, the lower end of the plate 22 and the upper end of the pipe member 40 are connected using a bonding agent. An inner diameter A of the through-hole 32 of the commode 2 is larger than an outer diameter B of the pipe member 40. Also, the pipe member 40 is inserted into the through-hole 32. Thereby, the water supply hose 20 or the power supply cord 18 that is inserted through the insertion through-hole 30 can be guided by the pipe member 40 into the through-hole 32. Thereby, the water supply hose 20 or the power supply cord 18 that is inserted through the insertion through-hole 30 can be inserted easily by the installer into the through-hole 32. In other words, the toilet device main unit 8 that has good installability for the commode 2 can be provided.

The inner diameter A of the through-hole 32 of the commode 2 is larger than an inner diameter C of the insertion through-hole 30. Thereby, the water supply hose 20 or the power supply cord 18 that is inserted through the insertion through-hole 30 can be inserted easily into the through-hole 32. In other words, the toilet device main unit 8 that has good installability for the commode 2 can be provided.

Also, the inner diameter C of the insertion through-hole 30 is smaller than an inner diameter D of the pipe member 40. Thereby, the water supply hose 20 or the power supply cord 18 that is inserted through the insertion through-hole 30 can be inserted easily into the pipe member 40. In other words, the toilet device main unit 8 that has good installability for the commode 2 can be provided.

Thereby, according to the toilet device 4 of the embodiment, the insertion through-hole 30 is provided in the plate 22, where the water supply hose 20 or the power supply cord 18 that is connected to the toilet device main unit 8 is insertable through the insertion through-hole 30. Thereby, the water supply hose 20 or the power supply cord 18 is concealed in the interior of the commode 2 through the insertion through-hole 30 and the through-hole 32 of the commode 2. Thereby, the exposure of the water supply hose 20 or the power supply cord 18 outside the commode 2 can be suppressed. Accordingly, the design quality of the commode 2 can be improved.

Also, according to the toilet device 4, the packing 24 that covers the outer circumference of the lower surface of the plate 22 is included. Thereby, the liquid waste can be prevented from entering the interior space 34 of the commode 2 through the through-hole 32.
