Furthermore, the upper and lower parts in Figure 1 will be described as the upper and lower parts of the toilet unit 10, respectively.

[0033] Figure 2 is a front view showing the toilet unit 10 with the toilet bowl 20 removed according to the embodiment. Figure 3 is a perspective view showing the toilet unit 10 with the toilet bowl 20 removed according to the embodiment. As shown in Figures 2 and 3, the front panel 40 is provided with a single opening 40A that opens in the front-to-back direction. The water supply pipe WP and the drain pipe DP connected to the toilet bowl 20 are inserted through the opening 40A. The front panel 40 is divided into a lower panel 42 that constitutes the lower part of the front panel 40 and an upper panel 44 that constitutes the upper part of the front panel 40.

[0034] The lower panel 42 is provided with a first notch 42A that opens upward. The lower part of the upper panel 44 is provided with a second notch 44A that opens downward. When the lower panel 42 and the upper panel 44 are assembled, the opening of the first notch 42A and the opening of the second notch 44A connect, thereby forming a single opening 40A.

[0035] On both the left and right sides of the first notch 42A in the lower panel 42, a pair of bolt holes 42B are provided through which mounting bolts 68, described later, are inserted. Near the left bolt hole 42B, a hose hole (through hole) 42C is provided through which a water supply hose 70, described later, is inserted. The configuration of the opening 40A will be explained in detail later. The pair of bolt holes 42B and the hose hole 42C are formed independently of the first notch 42A. The hose hole 42C is located away from the first notch 42A and is exposed to the front even when the toilet 20 is installed in the cabinet 30.

[0036] The upper part of the upper panel 44 is provided with a top panel support member 34 for supporting the top panel that will be attached to the top of the cabinet body 32. Note that the cabinet 30 shown in Figures 1 and 2 is shown without the top panel attached. Door receivers such as push latches are attached to the top panel support member 34 to receive the doors 50 provided on the left and right sides of the cabinet body 32.

[0037] A stand 60 for supporting the toilet bowl 20 is provided on the inside of the cabinet 30, behind the front panel 40. The stand 60 comprises a pair of legs 62, a right-side panel 64R, a left-side panel 64L, and a connecting member 66. The pair of legs 62 are fixed to the floor surface FS of the toilet room and erect, supporting the toilet bowl 20 in a position spaced apart from the wall surface WS and floor surface FS of the toilet room. The right-side panel 64R and the left-side panel 64L are provided on the left and right sides of the stand 60 with both panel surfaces facing left and right. The connecting member 66 connects the right-side panel 64R and the left-side panel 64L at the top of the stand 60.

[0038] Furthermore, each leg portion 62 is provided with a mounting bolt portion 68 to which the toilet bowl 20 is attached. Each mounting bolt portion 68 is inserted through each bolt hole 42B and protrudes forward from the front plate 40. In addition, a large-diameter drain pipe insertion hole 60A is provided in the portion of the stand 60 that is exposed from the first notch 42A, through which the drain pipe DP connected to the toilet bowl 20 is inserted.

[0039] --Configuration of the opening-- Next, the configuration of the opening 40A provided in the front panel 40 will be described in detail.

[0040] Figure 4 is a front view of the lower panel 42 and upper panel 44 of the toilet unit 10 according to the embodiment. As shown in Figure 4, dowels 42b extending upward are provided on both the left and right sides of the upper surface 42a of the lower panel 42. On the other hand, dowel holes (not shown) into which the dowels 42b are inserted are provided on the lower surface 44a of the upper panel 44 at positions corresponding to each dowel 42b in the vertical direction. By inserting each dowel 42b into each dowel hole, the lower panel 42 and the upper panel 44 are attached to each other via the dowels 42b.

[0041] As shown in Figure 1, in the toilet unit 10, the height H1 from the floor surface FS inside the toilet room to the top surface 20a of the toilet bowl 20 is slightly greater than the height H2 from the floor surface FS to the top surface 42a of the lower panel 42. Therefore, the top surface 42a of the lower panel 42 is located below the top surface 20a of the toilet bowl 20. In addition, a heated bidet toilet seat can be installed on the top surface 20a of the toilet bowl 20.

[0042] Returning to Figure 4, the first notch 42A is cut out in a roughly concave shape downward from the upper surface 42a of the lower panel 42. The depth dimension of the first notch 42A is slightly larger than half the vertical dimension of the lower panel 42. The opening of the first notch 42A is covered by the toilet bowl 20 when the toilet bowl 20 is attached to the stand 60. On the other hand, the second notch 44A is cut out in a two-stage stepped shape that widens downward, and is symmetrical with respect to the left-right central part of the upper panel 44. That is, the second notch 44A is composed of a first stage portion that continues from its opening end 44c1 and a second stage portion that continues from the first stage (hereinafter, the first stage portion of the second notch 44A will be called the "first stage portion 44A1" and the second stage portion will be called the "second stage portion 44A2").

[0043] The width dimension W1 of the opening in the first stage section 44A1 is larger than the width dimension W2 of the opening in the second stage section 44A2. In other words, the opening end of the first stage section 44A1 (the opening end of the second notch 44A; hereinafter referred to as the "first opening end 44c1") is located further outward in the left-right direction than the opening end of the second stage section 44A2 (hereinafter referred to as the "second opening end 44c2"). The second opening end 44c2 is chamfered and has a rounded shape.

[0044] Furthermore, the width dimension W2 of the opening in the second section 44A2 is equal to the width dimension W3 of the opening in the first notch 42A. When the upper panel 44 is attached to the lower panel 42, the opening end 42c of the opening in the lower panel 42 and the second opening end 44c2 are in the same position in the left-right direction. Therefore, when the upper panel 44 is attached to the lower panel 42, the first opening end 44c1 is located outward in the left-right direction from the opening end 42c of the opening in the lower panel 42.

[0045] --Pipe and wiring routing patterns-- Next, the routing of piping and wiring in the toilet unit 10 will be described.

[0046] Figure 5 is a perspective view showing the routing of the water supply hose 70 and power plug 72B of the heated toilet seat during the installation process of the toilet unit 10 according to this embodiment. As shown in Figure 5, during the installation process of the toilet unit 10 according to this embodiment, the water supply pipe WP and drain pipe DP connected to the toilet bowl 20 are installed by being inserted into the opening 40A from the rear of the front plate 40. The water supply pipe WP is installed so as to protrude forward from the vicinity of the boundary between the first notch 42A and the second notch 44A to the front side of the opening 40A. The drain pipe DP is installed so as to protrude forward from the lower part of the opening of the first notch 42A to the front side of the opening 40A.

[0047] Furthermore, in the installation process of the toilet unit 10 in this embodiment, when a bidet toilet seat is attached to the upper surface 20a of the toilet bowl 20, the water supply hose 70 and power cord 72A connected to the bidet toilet seat are routed from the rear side to the front side of the front panel 40. The water supply hose 70 is inserted through the hose hole 42C and routed to the front side of the front panel 40. The power cord 72A has a power plug 72B at its end and is inserted through the second notch 44A of the opening 40A and routed to the front side of the front panel 40. Therefore, even when the toilet bowl 20 is attached to the front side of the front panel 40 and the opening of the first notch 42A is covered by the toilet bowl 20, the water supply hose 70 and power cord 72A can be easily routed to the front side of the front panel 40.

[0048] Here, the depth dimension D1 of the opening in the first stage section 44A1 (see Figure 4) is smaller than the thickness dimension T1 of the power plug 72B, and the depth dimension D2 of the opening in the second stage section 44A2 (see Figure 4) is larger than the thickness dimension T1 of the power plug 72B. Also, the depth dimension D1 of the opening in the first stage section 44A1 is larger than the diameter dimension of the power cord 72A.

[0049] --Effects of the Embodiment-- Next, the effects and advantages of the toilet unit 10 according to this embodiment will be described.

[0050] The toilet unit 10 according to this embodiment comprises a toilet bowl 20, a cabinet body 32 positioned behind the toilet bowl 20, a lower panel 42 covering the front of the cabinet body 32 and having a first cutout 42A that opens upward, and an upper panel 44 attached to the upper side of the lower panel 42, wherein at least the first cutout 42A forms one opening 40A for passing a water supply pipe WP and a drain pipe DP connected to the toilet bowl 20.

[0051] With this configuration, during installation or maintenance of the toilet unit 10, the water supply pipe WP and drain pipe DP of the toilet bowl 20 can be inserted through the opening 40A without removing the lower panel 42 and upper panel 44 from the cabinet body 32. Therefore, piping and wiring can be easily routed between the cabinet body 32 and the toilet bowl 20, improving work efficiency.

[0052] Furthermore, in the toilet unit 10, the upper panel 44 is provided with a second notch 44A that opens downwards, and the opening 40A is formed by the first notch 42A and the second notch 44A.

[0053] With this configuration, even if the opening of the first notch 42A is covered by the toilet bowl 20 being mounted on the front side of the lower panel 42, the water supply hose 70 and power cord 72A connected to the bidet toilet seat can still be inserted through the opening of the second notch 44A. Therefore, when installing the bidet toilet seat on the upper surface 20A of the toilet bowl 20, it becomes easier to route the water supply hose 70 and power cord 72A to the front side of the lower panel 42 and upper panel 44, further improving work efficiency.

[0054] Furthermore, in the toilet unit 10, the second notch 44A is notched in a stepped manner that widens downwards.

[0055] This configuration ensures visibility of the opening 40A even when the opening of the first notch 42A is covered by the toilet bowl 20. Furthermore, the larger of the two stepped openings of the second notch 44A provides sufficient opening width for routing the water supply hose 70 and power cord 72A.

[0056] Furthermore, in the toilet unit 10, the second notch 44A is cut symmetrically on both sides.

[0057] This configuration allows for adjustments to be made regardless of whether the routing of the water supply hose 70, power cord 72A, etc., is to the right or left depending on the location of the work site.

[0058] Furthermore, in the toilet unit 10, the second notch 44A is formed in a two-stage staircase shape, with the width dimension W1 of the opening of the first stage portion 44A1 being larger than the width dimension W2 of the opening of the second stage portion 44A2.

[0059] With this configuration, the first section 44A1 improves work efficiency when routing water supply hoses 70 and power cords 72A, and the second section 44A2 improves visibility and design by having a smaller opening compared to the first section 44A1.

[0060] In addition, in the toilet unit 10, a heated bidet toilet seat is positioned on the upper surface 20a of the toilet bowl 20. The second notch 44A has an opening depth D1 of the first stage portion 44A1 that is smaller than the thickness T1 of the power plug 72B connected to the heated bidet toilet seat, and an opening depth D2 of the second stage portion 44A2 that is larger than the thickness T1 of the power plug 72B.

[0061] This configuration allows the power plug 72B to be easily inserted into the opening of the second notch 44A, ensuring ease of routing the power plug 72B.

[0062] Furthermore, in the toilet unit 10, the second opening end 44c2 is chamfered.

[0063] This configuration makes it possible to prevent the worker's hands from being injured by the second open end 44c2 when inserting, for example, a power cord 72A or the like into the second notch 44A.

[0064] In addition, in the toilet unit 10, a hose hole 42C is formed in the lower panel 42, which is independent of the first notch 42A.

[0065] With this configuration, the installation of the bidet toilet seat can be made easier by inserting the water supply hose 70, etc., of the bidet toilet seat, which is located on the upper surface 20a of the toilet bowl 20, into the hose hole 42C.

[0066] In addition, in the toilet unit 10, the lower panel 42 and the upper panel 44 are attached to each other via a pair of dowels 42b provided on the lower panel 42.

[0067] This configuration makes it easier to install the lower panel 42 and the upper panel 44.

[0068] Furthermore, in the toilet unit 10, the upper surface 42a of the lower panel 42 is located lower than the upper surface 20a of the toilet bowl 20.

[0069] With this configuration, a portion of the boundary between the lower panel 42 and the upper panel 44 is covered by the toilet bowl 20, which allows for easy routing of the power cord 72A for the heated bidet toilet seat located above the toilet bowl 20 while maintaining a pleasing design.

[0070] Furthermore, the cabinet 30 according to this embodiment comprises a cabinet body 32, a lower panel 42 that covers the front side of the cabinet body 32 and is provided with a first cutout 42A that opens upward, and an upper panel 44 that is attached to the upper side of the lower panel 42 and has at least one opening 40A formed by the first cutout 42A for passing a water supply pipe WP and a drain pipe DP connected to the toilet bowl 20.

[0071] With this configuration, the water supply pipe WP and drain pipe DP of the toilet bowl 20 can be inserted through the opening 40A without removing the lower panel 42 and upper panel 44 from the cabinet body 32. Therefore, it is possible to easily route piping and wiring between the cabinet body 32 and the toilet bowl 20, resulting in a cabinet 30 that improves work efficiency.

[0072] Furthermore, in the toilet unit 10, the hose hole 42C is located away from the first notch 42A and is exposed to the front even when the toilet bowl 20 is installed in the cabinet 30. Therefore, even when the toilet bowl 20 is installed in the cabinet 30, the water supply hose 70 of the bidet toilet seat can be inserted through the hose hole 42C, making the installation of the bidet toilet seat even easier.

[0073] Furthermore, in the toilet unit 10, the depth dimension D1 of the opening in the first stage portion 44A1 is larger than the diameter dimension of the power cord 72A. As a result, the power cord 72A can be inserted through the opening formed between the upper surface 42a of the lower panel 42 and the first stage portion 44A1, making the installation of the heated toilet seat even easier.

[0074] Furthermore, in the toilet unit 10, the opening end 42c and the second opening end 44c2 of the opening in the lower panel 42 coincide in the left-right direction. Therefore, in the process of forming the opening 40A of the front plate 40, the opening of the first notch 42A and the opening of the second stage portion 44A2 can be formed in a single, continuous manner. As a result, the process of forming the opening 40A can be simplified.

[0075] <Variation> The embodiments described above are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and essence of the invention, as well as in the claims of the invention and its equivalents.

[0076] For example, in the above embodiment, the front panel was shown to be divided into two parts vertically, consisting of an upper panel and a lower panel. However, the front panel may also be divided into three parts vertically, consisting of an upper panel, a lower panel, and another panel (a panel positioned above the upper panel or below the lower panel). Alternatively, the front panel may be divided into two parts horizontally.

[0077] Furthermore, in the above embodiment, an example was shown in which the first notch is formed in a substantially concave shape and the second notch is formed in a two-step staircase shape. However, the shapes of the first and second notches may be, for example, a staircase shape with three or more steps, a continuous tapered shape, or an arc shape.

[0078] Furthermore, although the above embodiment illustrates a configuration in which the shape of the second notch is symmetrical, a configuration in which it is asymmetrical is also possible.

[0079] Furthermore, the above embodiment illustrates a configuration in which the lower panel and the upper panel are attached to each other via dowels. However, the lower panel and the upper panel may also be attached to each other via, for example, magnets or positioning pins.

[0080] Furthermore, in the above embodiment, a configuration may be provided around the opening that includes clamps or grooves that function as wiring guides.
