Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the washbasin unit as described in Patent Document 1, in addition to the holes for inserting the water supply pipe, the drain pipe, etc., it is necessary to provide attachment holes for attaching the washbasin in the plate-like member. However, when attaching another washbasin with a different attachment position to the cabinet, it was necessary to prepare another cabinet provided with attachment holes at the corresponding positions. For this reason, a common cabinet could not be used for another washbasin with a different attachment position.

[0006] The present invention has been made in view of such problems, and an object thereof is to provide a cabinet and a washbasin unit capable of achieving commonization of the cabinet. [Means for solving the problem]

[0007] To solve the above problems, a cabinet according to a first aspect of the present invention comprises a pair of side plates that cover a water supply pipe and a drain pipe connected to a washbasin from the side, a plate-shaped member having a water supply hole through which the water supply pipe is inserted, a drain hole through which the drain pipe is inserted, a first mounting hole through which a first washbasin can be installed as the washbasin, and a second mounting hole through which a second washbasin, which is installed in a different position from the first washbasin, can be installed as the washbasin.

[0008] With this configuration, the first washbasin can be attached to the plate-shaped member using the first mounting hole, and the second washbasin can be attached to the plate-shaped member using the second mounting hole. In this way, since both the first and second washbasins, which are mounted in different positions, can be attached to the same plate-shaped member, cabinet commonality can be achieved.

[0009] Furthermore, the cabinet according to the second aspect of the present invention includes a front panel provided on the front side of the space enclosed by the plate-shaped member and the pair of side panels, and the second mounting hole is provided on the front panel side of the first mounting hole.

[0010] With this configuration, for example, if the cabinet is installed so that the rear of the cabinet is flush with the wall, the second mounting hole will be located on the front side rather than the wall side where installation of the washbasin is difficult. This improves the ease of installation of the second washbasin to the plate-like member.

[0011] Furthermore, in the cabinet according to the third aspect of the present invention, each of the first mounting holes and the second mounting holes is provided in a pair.

[0012] With this configuration, the first and second washbasins can be attached to the plate-like member at two locations, allowing the washbasins to be firmly attached to the plate-like member.

[0013] Furthermore, in the cabinet according to the fourth aspect of the present invention, when the direction in which the pair of side plates are provided with respect to the plate-like member is defined as the left-right direction, the plate surface of the plate-like member is horizontally elongated in the left-right direction, and each of the pair of first mounting holes and the pair of second mounting holes are arranged to face each other in the left-right direction, with the drain hole in between.

[0014] In this configuration, the washbasin is supported by a drain pipe attached to the drain hole. Therefore, by attaching the washbasin on both sides of the position supported by the drain pipe, the washbasin can be attached more securely to the plate-like member.

[0015] Furthermore, in the cabinet according to the fifth aspect of the present invention, when the direction in which the pair of side plates are provided with respect to the plate-like member is defined as the left-right direction, at least one of the pair of first mounting holes is provided such that it does not overlap with at least one of the pair of second mounting holes in the front-rear direction, which is perpendicular to the left-right direction and is along the plate surface of the plate-like member.

[0016] For example, if the first mounting hole and the second mounting hole are arranged to overlap in the front-to-back direction, the distance between the first and second mounting holes becomes narrow, raising concerns about a decrease in the strength of the plate-like member. With the above configuration, it is possible to prevent the distance between the first and second mounting holes from becoming narrow, and thus prevent a decrease in the strength of the plate-like member.

[0017] Furthermore, in the cabinet according to the sixth aspect of the present invention, at least one of the first mounting hole and the second mounting hole is provided in an oval shape.

[0018] With this configuration, even if the mounting position of the washbasin on the plate-shaped member is slightly misaligned in the direction of the long axis of each oval-shaped mounting hole, the washbasin can still be attached to the plate-shaped member. Therefore, even if there is a manufacturing error in the direction of the long axis regarding the mounting position of the washbasin on the plate-shaped member, the washbasin can still be firmly attached.

[0019] The hand-washing device unit according to the present invention includes the above cabinet and the hand-washing device placed on the plate-like member and attached to the plate-like member.

[0020] According to this configuration, a hand-washing device unit capable of achieving common use of the cabinet can be realized.

Effects of the Invention

[0021] According to the cabinet and the hand-washing device unit of the present invention, common use of the cabinet can be achieved.

Modes for Carrying Out the Invention

[0023] <First Embodiment> Hereinafter, the first embodiment of the present invention will be described.

[0024] ——Overall Configuration—— Figure 1 is a perspective view showing the external configuration of a hand basin unit 10 according to the first embodiment. The hand basin unit 10 shown in Figure 1 comprises a cabinet 20 and a horizontally elongated rectangular hand basin (first hand basin) 30 mounted on the cabinet 20. The hand basin unit 10 is installed, for example, along the wall of a toilet room. A door (front panel) 22A and a lower panel 22B are provided on the front side of the cabinet 20.

[0025] Figure 2 is a perspective view showing the internal configuration of the washbasin unit 10 according to the first embodiment, and is a perspective view of the inside of the cabinet 20 seen from diagonally above. Figure 3 is a perspective view showing the internal configuration of the washbasin unit 10 according to the first embodiment, and is a perspective view of the inside of the cabinet 20 seen from diagonally below. As shown in Figures 2 and 3, the cabinet 20 comprises a pair of side plates 24, a top plate (plate-shaped member) 26, a first support plate 27, a partition plate 28, and a second support plate 29. Inside the cabinet 20, a space S1 is formed surrounded by the pair of side plates 24 and the top plate 26.

[0026] In the following description, the side with the door 22A and lower panel 22B will be referred to as the front of the washbasin unit 10, and the opposite side as the rear of the washbasin unit 10. Furthermore, the direction in which the pair of side panels 24 are provided will be referred to as the left-right direction of the washbasin unit 10 (the right side in Figure 1 will be referred to as the right). Also, the direction in which the pair of side panels 24 rise will be referred to as the up-down direction of the washbasin unit 10 (the upper side in Figure 1 will be referred to as the up).

[0027] The washbasin 30 is a so-called vessel-type washbasin and comprises a counter 32, a sink 34, and a faucet 36. The counter 32 is a plate-shaped member and is mounted on the cabinet 20 with both plate surfaces facing up and down. The sink 34 has a horizontally elongated rectangular shape and is mounted on the counter 32. The faucet 36 is located above the sink 34.

[0028] As shown in Figures 2 and 3, a pair of hinges B1 are provided on the front of the left side panel 24. A magnetic catch M1 is provided on the front of the right side panel 24. The door 22A opens from the right to the front, with the rear of the left end supported by the pair of hinges B1, and closes when the rear of the right end is attracted to the magnetic catch M1. In the cabinet 20, the side opposite to the side where the door 22A is located (the rear side) is open. Therefore, if the rear of the cabinet 20 is installed along a wall such as that of a toilet room, the opening on the rear side of the cabinet 20 will be covered by the wall.

[0029] The lower panel 22B is attached to the underside of the door 22A by a mounting jig B2. The pair of side panels 24 are erected vertically with a gap between them, with both panel surfaces facing left and right. Two adjustment members 24A for adjusting the height of the cabinet 20 are provided on the underside of each side panel 24, spaced apart in the front-to-back direction. In other words, the cabinet 20 has four adjustment members 24A. Each adjustment member 24A is a so-called screw-type adjuster, and the height can be adjusted by changing the degree to which it is screwed into the underside of each side panel 24. Therefore, the height at which the cabinet 20 is installed can be adjusted at the four corners of the underside of the cabinet 20.

[0030] The countertop 26 is horizontally elongated in the left-right direction and is slightly smaller than the counter 32 of the washbasin 30. It is mounted sandwiched between the upper ends of each side plate 24 with both plate surfaces facing in the up-down direction. In the washbasin unit 10, the counter 32 of the washbasin 30 is positioned so as to overlap the countertop 26. The first support plate 27 is mounted to support the rear end of the underside of the countertop 26 with both plate surfaces facing in the front-back direction.

[0031] The partition plate 28 is installed between the side plates 24 at the boundary between the door 22A and the lower panel 22B, with both plate surfaces facing vertically. The partition plate 28 divides the space S1 inside the cabinet 20 into the space inside the door 22A and the space inside the lower panel 22B. The partition plate 28 is provided with a first insertion hole 28a through which a water supply pipe 40 is inserted, and a second insertion hole 28b through which a drain pipe 50 is inserted. The second support plate 29 is installed to support the rear end of the lower surface of the partition plate 28 with both plate surfaces facing front to back. The second support plate 29 is provided with a roughly rectangular cutout 29a that opens downwards, approximately in the center in the left-right direction.

[0032] In the washbasin unit 10, a water supply pipe 40 and a drain pipe 50 are connected to the washbasin 30. The water supply pipe 40 and the drain pipe 50 are provided to extend downward from the washbasin 30 in the space S1 inside the cabinet. The upper end of the water supply pipe 40 is a water inlet 40a that connects to the faucet 36 of the washbasin 30. A shut-off valve 42 is provided at the lower end of the water supply pipe 40, which is located in the space inside the lower panel 22B. A roughly short cylindrical drain unit 52 is attached to the upper end of the drain pipe 50. The opening at the upper end of the drain unit 52 is a drain outlet 50a that connects to the sink 34 of the washbasin 30. In this embodiment, the cabinet 20 functions as a pipe cover that covers the water supply pipe 40 and the drain pipe 50 extending from the washbasin 30.

[0033] Furthermore, as shown in Figure 3, the cabinet 20 includes a mounting plate 60 positioned in contact with the underside of the top plate 26, and a mounting unit 62 positioned in contact with the underside of the mounting plate 60. The mounting plate 60 is, for example, a metal plate-shaped member, and is attached to the washbasin 30 with both plate surfaces facing vertically. The mounting unit 62 is substantially plate-shaped, and is attached to the mounting plate 60 with both plate surfaces facing vertically. In the washbasin unit 10, the washbasin 30 is attached to the cabinet 20 such that the top plate 26 is sandwiched between the washbasin 30 and the mounting plate 60. The mounting configuration of the washbasin 30 will be described in detail later.

[0034] --Tabletop construction-- Next, we will explain the configuration of the top panel 26 in detail.

[0035] Figure 4 is a plan view of the top plate 26 according to the first embodiment, viewed from above. As shown in Figure 4, the top plate 26 is provided with a water supply hole 26a through which a water supply pipe 40 is inserted and a drain hole 26b through which a drain pipe 50 is inserted. The water supply hole 26a is located near the right edge of the top plate 26 and has an elongated oval shape that is larger in diameter than the water supply opening 40a. The drain hole 26b is located approximately in the center of the top plate 26 and has a circular shape that is larger in diameter than the drain opening 50a.

[0036] The top plate 26 is further provided with a pair of first mounting holes H1 and a pair of second mounting holes H2. The pair of first mounting holes H1 are elongated ovals in the left-right direction, with one located at the rear right end of the top plate 26 and the other located approximately in the center in the front-to-back direction at the left end of the top plate 26. The pair of second mounting holes H2 are elongated ovals in the left-right direction, with one located at the front right side of the top plate 26 and the other located at the front left side of the top plate 26. The pair of second mounting holes H2 are also arranged in parallel with a gap between them so as to overlap in the left-right direction. Each second mounting hole H2 is located in front of each first mounting hole H1.

[0037] Each of the pair of first mounting holes H1 and the pair of second mounting holes H2 is arranged to face each other in the left-right direction, with the drain hole 26b in between. Furthermore, the first mounting hole H1 located at the left end of the top plate 26 and the second mounting hole H2 located slightly to the left of the top plate 26 are arranged so as not to overlap in the front-to-back direction. Furthermore, the first mounting hole H1 located at the right end of the top plate 26 and the second mounting hole H2 located slightly to the right of the top plate 26 are arranged so as not to overlap in the front-to-back direction.

[0038] In the washbasin unit 10, both the pair of first mounting holes H1 and the pair of second mounting holes H2 function as holes for mounting the washbasin 30. The pair of first mounting holes H1 are holes for mounting the washbasin 30 of this embodiment, and the pair of second mounting holes H2 are holes for mounting a second washbasin whose mounting position on the countertop 26 is different from that of the washbasin 30.

[0039] --Installation methods for washbasins-- Next, the mounting configuration of the washbasin 30 to the cabinet 20 will be described in detail.

[0040] Figure 5 is an exploded perspective view showing the procedure for attaching the washbasin 30 to the countertop 26 and mounting plate 60 in the first embodiment. Figure 6 is a perspective view showing the attachment configuration of the washbasin 30 to the countertop 26 and mounting plate 60 in the first embodiment. As shown in Figures 5 and 6, the counter 32 is provided with a counter-side water supply hole 32a at a position overlapping with the water supply hole 26a, a counter-side drain hole 32b at a position overlapping with the drain hole 26b, and counter-side mounting holes 32c at positions overlapping with each of the first mounting holes H1.

[0041] The water supply hole 32a on the counter side is circular in shape, slightly smaller than the water supply hole 26a. The lower end of the faucet 36 is exposed from the opening of the water supply hole 32a on the counter side. The drain hole 32b on the counter side is circular in shape, slightly larger than the drain hole 26b. A drain connection port 34B, which extends cylindrically from the bottom of the sink 34, protrudes downward from the opening of the drain hole 32b on the counter side. Each mounting hole 32c on the counter side is an elongated oval shape, similar to each first mounting hole H1, and is approximately the same size as each first mounting hole H1. Mounting pins 34A extending from the washbasin 30 protrude downward from the opening of each mounting hole 32c on the counter side.

[0042] Each mounting pin 34A is provided on the washbasin 30 and is a pin-shaped member for attaching the washbasin 30 to the cabinet 20 by being attached to the mounting plate 60 via the countertop 26. A roughly short cylindrical mounting cap 70 can be attached to the tip of each mounting pin 34A. In the first embodiment, the mounting position of the washbasin 30 relative to the countertop 26 is determined by the position where the mounting pins 34A are provided.

[0043] The inner diameter of the drain unit 52 is slightly larger than the outer diameter of the drain connection port 34B of the sink 34. Therefore, the drain connection port 34B can be inserted into the drain unit 52. In addition, the outer diameter of the lower end of the drain unit 52 is slightly smaller than the inner diameter of the drain hole 26b. Therefore, the lower end of the drain unit 52 can be fitted into the drain hole 26b.

[0044] The mounting plate 60 is provided with a pair of extensions 60A that extend outward in a roughly rectangular shape from both the left and right sides. Each extension 60A is positioned to overlap with each of the first mounting holes H1 of the top plate 26. Each extension 60A is provided with a circular opening 60a. Each circular opening 60a is formed to be slightly smaller than the outer diameter of the mounting cap 70. In addition, a circular drainage opening 60b is provided in the approximate center of the mounting plate 60, where it overlaps with the drainage hole 26b of the top plate 26.

[0045] The mounting unit 62 has a plate-shaped portion 62A that is roughly rectangular in shape, and a cylindrical portion 62B that extends downward from approximately the center of the plate-shaped portion 62A in a cylindrical shape. The mounting unit 62 is attached to the lower surface of the mounting plate 60 such that the plate-shaped portion 62A covers the drain opening 60b. The four corners of the plate-shaped portion 62A are screwed to the mounting plate 60 by mounting screws 72. The drain pipe 50 is attached to the lower end of the cylindrical portion 62B.

[0046] The mounting plate 60, mounting unit 62, and washbasin 30 to the countertop 26 are installed using the following procedure, for example. First, the mounting unit 62 is attached to the underside of the mounting plate 60 using mounting screws 72. Next, the mounting plate 60 is placed on top of the underside of the countertop 26 so that the drain holes 26b and the drain openings 60b correspond to each other. In this state, each first mounting hole H1 and each circular opening 60a are aligned. Next, the drain unit 52 is fitted into the drain holes 26b from above the countertop 26.

[0047] Next, the hand basin 30 is placed on the countertop 26, with each mounting pin 34A protruding downward from each counter-side mounting hole 32c being inserted into each first mounting hole H1 of the countertop 26. As a result, the tips of each mounting pin 34A protrude downward through the circular opening 60a. Next, mounting caps 70 are attached to the tips of each mounting pin 34A so that the countertop 26 is sandwiched between the counter 32 and the mounting plate 60.

[0048] By following the above procedure, the countertop 26 is sandwiched and held between the washbasin 30 and the mounting plate 60, and the washbasin 30 is mounted on the countertop 26. Then, the countertop 26 with the washbasin 30 mounted on it is attached to the cabinet 20, thereby mounting the washbasin 30 to the cabinet 20. The above mounting procedure is just one example, and the procedure for mounting the washbasin 30 to the countertop 26 is not limited to the procedure described above. For example, the washbasin 30 and the mounting plate 60 may be mounted to a countertop 26 that has been previously installed between a pair of side plates 24.

[0049] In the first embodiment of the washbasin unit 10, other washbasins that have different mounting positions on the countertop 26 than the washbasin 30, specifically other washbasins in which the mounting pins 34A are inserted through the second mounting holes H2 when the washbasin 30 is placed on top of the countertop 26, can also be mounted on the same countertop 26 without changing the cabinet 20. The procedure for mounting other washbasins to the countertop 26 is the same as the procedure described above, except that the position through which the mounting pins 34A are inserted is different.

[0050] --Effects of the First Embodiment-- Next, the effects and advantages of the cabinet 20 and washbasin unit 10 according to the first embodiment will be described.

[0051] The cabinet 20 according to the first embodiment includes a pair of side plates 24 that cover the water supply pipe 40 and the drain pipe 50 connected to the washbasin 30 from the side. Furthermore, the cabinet 20 includes a top plate 26 having a water supply hole 26a through which the water supply pipe 40 is inserted, a drain hole 26b through which the drain pipe 50 is inserted, a first mounting hole H1 for which the first washbasin 30 can be installed as a washbasin, and a second mounting hole H2 for which a second washbasin, which is installed in a different position from the first washbasin 30, can be installed as a washbasin.

[0052] With this configuration, the first washbasin 30 can be attached to the countertop 26 using the first mounting hole H1, and the second washbasin can be attached to the countertop 26 using the second mounting hole H2. In this way, since both the first washbasin 30 and the second washbasin, which are attached in different positions, can be attached to the same countertop 26, it is possible to standardize the cabinet 20 for which different types of washbasins 30 can be attached.

[0053] Furthermore, the cabinet 20 includes a door 22A provided on the front side of the space S1 enclosed by the top plate 26 and a pair of side plates 24, and the second mounting hole H2 is provided on the door 22A side of the first mounting hole H1.

[0054] With this configuration, for example, if the cabinet 20 is installed so that its rear is flush against the wall, the second mounting hole H2 will be located on the front side rather than the wall side, which would make the installation of the washbasin 30 difficult. This improves the ease of installation of the second washbasin on the countertop 26.

[0055] Furthermore, in the cabinet 20, each of the first mounting hole H1 and the second mounting hole H2 is provided in a pair.

[0056] With this configuration, the first washbasin 30 and the second washbasin can be attached to the countertop 26 at two locations, so that the washbasin 30 can be firmly attached to the countertop 26.

[0057] Furthermore, in the cabinet 20, when the direction in which the pair of side plates 24 are provided relative to the top plate 26 is defined as the left-right direction, the surface of the top plate 26 is horizontally elongated in the left-right direction, and each of the pair of first mounting holes H1 and the pair of second mounting holes H2 is arranged to face each other in the left-right direction, with the drain hole 26b in between.

[0058] In this configuration, the washbasin 30 is supported by a drain pipe 50 attached to the drain hole 26b. Therefore, by attaching the washbasin 30 on both sides of the position supported by the drain pipe 50, the washbasin 30 can be attached more firmly to the countertop 26.

[0059] Furthermore, in the cabinet 20, when the direction in which the pair of side plates 24 are provided relative to the top plate 26 is defined as the left-right direction, one of the pair of first mounting holes H1 and one of the pair of second mounting holes H2, and the other of the pair of first mounting holes H1 and the other of the pair of second mounting holes H2 are arranged so that they do not overlap in the front-back direction, which is perpendicular to the left-right direction, along the surface of the top plate 26.

[0060] For example, if the first mounting hole H1 and the second mounting hole H2 are arranged to overlap in the front-to-back direction, the distance between the first mounting hole H1 and the second mounting hole H2 becomes narrow, raising concerns about a decrease in the strength of the top plate 26. With the above configuration, it is possible to prevent the distance between the first mounting hole H1 and the second mounting hole H2 from becoming narrow, and thus prevent a decrease in the strength of the top plate 26.

[0061] Furthermore, in the cabinet 20, each first mounting hole H1 and each second mounting hole H2 are provided in an oval shape.

[0062] With this configuration, even if the mounting position of the washbasin 30 on the countertop 26 is slightly misaligned in the direction of the long axis of each oval-shaped mounting hole H1, H2, the washbasin 30 can still be attached to the countertop 26. Therefore, even if there is a manufacturing error in the direction of the long axis of the mounting position of the washbasin 30 on the countertop 26, the washbasin 30 can still be firmly attached.

[0063] Furthermore, the handwashing unit 10 according to the first embodiment comprises the cabinet 20 described above and a handwashing basin 30 that is placed on and attached to the countertop 26.

[0064] This configuration makes it possible to realize a washbasin unit 10 that allows for the standardization of cabinets 20.

[0065] <Second Embodiment> The second embodiment of the present invention will now be described. In the description of the second embodiment, the explanation of configurations similar to those of the first embodiment will be simplified or omitted.

[0066] Figure 7 is a plan view of the countertop 126 as seen from above according to the second embodiment. The cabinet and washbasin unit according to the second embodiment differ from the first embodiment in the arrangement of the first mounting holes H101 and the second mounting holes H102 provided in the countertop 126. The other configurations are the same as in the first embodiment.

[0067] As shown in Figure 7, the top plate 126 according to the second embodiment is provided with a water supply hole 126a, a drain hole 126b, a pair of first mounting holes H101, and a pair of second mounting holes H102. The positions of the water supply hole 126a and the drain hole 126b on the top plate 126, as well as the shape and size of the water supply hole 126a and the drain hole 126b, are the same as those of the water supply hole 26a and the drain hole 26b in the first embodiment.

[0068] The pair of first mounting holes H101 are elongated ovals in the left-right direction, with one located approximately in the center of the front-to-back direction on the right side of the top plate 126 and the other located approximately in the center of the front-to-back direction on the left end of the top plate 126. The pair of second mounting holes H102 are elongated ovals in the left-right direction, with one located at the front of the right side of the top plate 126 and the other located at the front of the left side of the top plate 126. In the second embodiment, both the pair of first mounting holes H101 and the pair of second mounting holes H102 are arranged in parallel with a gap between them so as to overlap in the left-to-right direction.

[0069] In the cabinet and washbasin unit according to the second embodiment, the first washbasin can be attached to the countertop 126 using the first mounting hole H101, and the second washbasin can be attached to the countertop 126 using the second mounting hole H102. In this way, since both the first and second washbasins, which are mounted in different positions, can be attached to the same countertop 126, it is possible to standardize cabinets for which different types of washbasins are attached.

[0070] Furthermore, in the cabinet and washbasin unit according to the second embodiment, both the first and second washbasins, which are mounted in different positions, are mounted along the long side of the countertop 126. Therefore, both the first and second washbasins can be firmly attached to the countertop 126.

[0071] <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.

[0072] For example, in each of the embodiments described above, mounting pins 34A and mounting caps 70 were given as examples of members for attaching the washbasin 30 to the countertops 26 and 126, but the invention is not limited thereto.
