Description

[Technical Field]

[0001] The present invention relates to a washbasin having a bowl portion. [Background technology]

[0002] BACKGROUND ART Wash basins having a bowl portion have been widely used.

[0003] For example, Patent Document 1 (JP 2021-80720 A) describes a washbasin that includes a bowl portion 110 having a bottom bowl surface portion 114 with a drain outlet 115 formed therein, and a front bowl surface portion 120 that is provided forward of the bottom bowl surface portion 114 and is formed so that the distance between the front edge and the drain outlet 115 increases as the distance from the drain outlet 115 to the left and right increases, as shown in Figures 6 and 7 (which correspond to Figures 14 and 17 of Patent Document 1, but with the addition of "100" to the two-digit reference number), and the front bowl surface portion 120 has a convex portion 122 with a convex surface 122A extending in the left-right direction, and an overflow hole 241 formed in the front bowl surface portion 120 below the top of the convex surface 122A.

[0004] The washbasin described in Patent Document 1 makes it easy to reach into from the front, and splashes are less likely to go over the convex portion 122 and fly out of the front bowl (see paragraph 0048 of Patent Document 1). Also, water flowing forward can be released through overflow hole 241, and splashes are less likely to go over the convex portion 122 and fly forward of the front bowl surface (see paragraph 0059 of Patent Document 1). Furthermore, the washbasin described in Patent Document 1 is easy to use because splashes are less likely to fly, and it also has a high design quality. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-80720 Summary of the Invention [Problem to be solved by the invention]

[0006] The inventors of the present invention have been conducting extensive research into how to improve the space utilization efficiency of, for example, a bathroom by reducing the area occupied in plan view by a counter on which a washbasin is placed.

[0007] We also discovered that by placing the washbasin so that it "protrudes" from the counter, it is possible to allocate the space adjacent to the left and right of the "protruding" part of the washbasin (previously occupied by the front end of the counter) to, for example, the track of the opening and closing door of the adjacent bathroom, without impairing its functionality as a washbasin (specifically, the sufficient size of the bowl portion).

[0008] Furthermore, the inventor of the present invention discovered that by providing the overflow hole in the "protruding" part of the washbasin, it is possible to ensure a sufficient size of the bowl portion, and the overflow outlet becomes less visible to the user of the washbasin, thereby enhancing the design.

[0009] The present invention was devised based on the above findings. The object of the present invention is to provide a washbasin that can improve the space utilization efficiency of the installation space, while ensuring a sufficient bowl size and high design quality. [Means for solving the problem]

[0010] The present invention is a washbasin that is installed so that a portion of it extends beyond the counter, and is characterized by having a protruding portion that extends beyond the counter when installed, a bowl portion that partially extends into the protruding portion, a drain opening into the bowl portion at the rear side of the bowl portion, and an overflow hole that opens into the bowl portion at the protruding portion.

[0011] According to this invention, the washbasin is installed so that it "protrudes" from the counter, so the space adjacent to the protruding part of the washbasin (conventionally occupied by the counter) can be allocated to, for example, the track of the door to the adjacent bathroom, without impairing its functionality as a washbasin (specifically, the sufficient size of the bowl). In other words, the space in which the washbasin is installed can be used more efficiently.

[0012] Furthermore, according to the present invention, by providing the overflow hole in the protruding part of the washbasin, it becomes easier to ensure a sufficient size of the bowl portion, and the overflow hole becomes less visible to the user of the washbasin, thereby improving the design.

[0013] In the present invention, it is preferable that the protruding portion protrudes forward of the washbasin mounting portion of the counter when installed, and that the overflow hole is located forward of the front end of the washbasin mounting portion of the counter.

[0014] With this, the washbasin is installed so that it "protrudes" from the front side of the counter, and the space adjacent to the left and right of the protruding part of the washbasin (previously occupied by the front end of the counter) can be allocated, for example, to the track of an opening and closing door, without impairing its function as a washbasin (specifically, the sufficient size of the bowl portion).

[0015] It is also preferable that the overflow hole is located above the upper end of the washbasin mounting portion of the counter.

[0016] This allows the overflow hole to be provided at any suitable position.

[0017] It is also preferable that the underside of the washbasin be provided with a recess that faces the upper edge of the apron portion of the washbasin placement portion of the counter.

[0018] This allows the recess and the upper edge of the apron to be fitted or engaged with each other, thereby easily positioning or temporarily fixing them together.

[0019] It is also preferable that the overflow hole is connected to the drain outlet via an overflow flow path, and that the overflow flow path is formed with a downward slope from the protruding portion side to the rear side in the front-to-rear direction.

[0020] This ensures that the overflow hole functions reliably.

[0021] It is also preferable that the volume of the overflow flow path in the area located within the protruding portion is larger than the volume of the area located above the washbasin mounting portion.

[0022] This effectively prevents backflow from occurring in the overflow passage.

[0023] Alternatively, it is preferable that a throttle portion is formed in the overflow passage midway from the protruding portion side to the rear side in the front-rear direction.

[0024] This also makes it possible to effectively prevent backflow from occurring in the overflow passage.

[0025] As an example of dimensions, the protruding portion may extend 70 mm or more in front of the washbasin mounting portion of the counter when installed, or the length of the protruding portion in the front-to-rear direction may be 15% or more of the length of the washbasin in the front-to-rear direction. [Effects of the Invention]

[0026] According to this invention, the washbasin is installed so that it "protrudes" from the counter, so the space adjacent to the protruding part of the washbasin (conventionally occupied by the counter) can be allocated for, for example, the track of an opening and closing door, without impairing the function of the washbasin (specifically, the sufficient size of the bowl). In other words, the space utilization efficiency of the installation space of the washbasin can be improved. Furthermore, according to the present invention, by providing the overflow hole in the protruding part of the washbasin, it becomes easier to ensure a sufficient size of the bowl portion, and the overflow hole becomes less visible to the user of the washbasin, thereby improving the design.

DETAILED DESCRIPTION OF THE INVENTION

[0028] (Basic configuration) An embodiment of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a schematic perspective view showing a washbasin 10 according to an embodiment of the present invention installed on a counter 20. Fig. 2 is a plan view showing the washbasin 10 according to this embodiment, and Fig. 3 is a vertical cross-sectional view showing the washbasin 10 according to this embodiment. The washbasin 10 of this embodiment is made of ceramic (an example of a baked product).

[0029] As shown in FIG. 1, the washbasin 10 of this embodiment is installed so that a portion of its front side (user side, near side) extends forward beyond the front end of the washbasin mounting portion of the counter 20.

[0030] Referring also to Figures 2 and 3, the width W in the left-right direction of the washbasin 10 in this embodiment is 50 to 55 cm, the length L in the front-to-back direction is 45 cm, and the height H1 from the top surface of the counter 20 to the upper edge of the washbasin 10 in the installed state is 5 to 7 cm.

[0031] In the installed state, the protruding length D in the front-to-back direction from the front of the apron portion 22 of the counter 20 to the front edge of the washbasin 10 is constant over almost the entire width W in the left-to-right direction, at 70 mm (more than 15% of the length L in the front-to-back direction of the washbasin 10). This area constitutes the protruding portion 11. The height H2 of the washbasin 10 in front of the protruding portion 11 is 12.5 cm. "H2-H1" is the hanging height of the front of the washbasin 10 (protruding portion 11) when the top surface of the counter 20 is used as the reference.

[0032] The bowl portion 12 of the washbasin 10 of this embodiment has a front area that extends to the protruding portion 11. A drain outlet 13 that opens into the bowl portion 12 is provided on the rear side of the bowl portion 12. The drain outlet 13 is a circular opening with a diameter of 4.4 cm, and its central axis is located in the center in the left-right direction and 38 cm from the front edge of the washbasin 10 in the front-to-back direction. The height H3 from the top edge of the washbasin 10 to the bottom of the drain outlet 13 is 16.7 cm.

[0033] The protruding portion 11 is also provided with an overflow hole 14 that opens into the bowl portion 12. The overflow hole 14 in this embodiment is configured as a long, narrow hole that is long in the left-right direction (approximately 6.3 cm wide x 1.0 cm high at the opening), and is located forward of the front end of the washbasin mounting portion of the counter 20 (the front end of the apron portion 22) (for example, located approximately 3 cm behind the front edge of the washbasin 10 in a plan view (see Figure 2)), and is located above the top surface of the counter 20 (therefore, above the upper end of the washbasin mounting portion of the counter 20) (for example, located approximately 4 cm behind the upper edge of the washbasin 10 in a vertical cross-sectional view (see Figure 2)).

[0034] As shown in Figure 3, the overflow hole 14 is connected to the drain outlet 13 via the overflow flow path 15, and the overflow flow path 15 is formed with a downward slope in the front-to-rear direction from the protruding portion 11 side toward the rear side (wall side, back side).

[0035] More specifically, the angle of inclination (of the bottom surface of overflow channel 15) in the front-to-rear direction in the area located within protruding portion 11 (the area shown by hatching in FIG. 3) is approximately 6.5°, and the angle of inclination (of the bottom surface of overflow channel 15) in the area located above the washbasin mounting portion of counter 20 (the area shown by matte finish in FIG. 3) is approximately 25°. Because the angles of inclination of these two areas are different (strictly speaking, because the upper surface of overflow channel 15 (the back surface of bowl portion 12) that spans both areas is a smoothly curved surface), overflow channel 15 of this embodiment has a throttle portion 15t formed midway in the front-to-rear direction from the protruding portion side to the rear side.

[0036] In addition, the overflow channel 15 of this embodiment is designed and configured so that the volume of the area located within the protruding portion 11 (the area shown by hatching in FIG. 3) is larger than the volume of the area located above the washbasin mounting portion of the counter 20 (the area shown by matte finish in FIG. 3). Specifically, in this embodiment, the former is approximately 515,000 mm 3 The latter is approximately 334,000 mm​3 is.

[0037] In addition, in FIG. 1, the item indicated by the dashed line and given the reference numeral 30 is a faucet device such as a faucet lever.

[0038] Next, Figure 4 is a bottom view showing the washbasin 10 of this embodiment, Figure 5(a) is a vertical cross-sectional view taken along line AA in Figure 4, Figure 5(b) is a vertical cross-sectional view taken along line BB in Figure 4, Figure 5(c) is a vertical cross-sectional view taken along line CC in Figure 4, and Figure 5(d) is a vertical cross-sectional view taken along line DD in Figure 4.

[0039] As shown in FIGS. 3 to 5, a pair of left and right recesses 16 facing the upper edge of the apron 22 of the counter 20 are provided on the underside of the washbasin 10 of this embodiment.

[0040] For example, the thickness of the apron 22 in the front-to-back direction is 17 mm, and the thickness of each recess 16 in the front-to-back direction is 34 mm, and when the washbasin 10 is placed on the counter 20, the upper end of the apron 22 and the recess 16 are positioned so that they overlap by 10 mm in the height direction. The two may abut in the height direction (in which case, their abutment can contribute to the positioning of the washbasin 10 in the height direction), or they may leave a gap in the height direction (in which case, the engagement or fitting between them can contribute to temporarily fixing the washbasin 10 (the positioning of the washbasin 10 in the height direction is handled by another part)).

[0041] (Action and effect) According to the present embodiment described above, the washbasin 10 is installed so that it "protrudes" from the counter 20, so the functionality of the washbasin 10 (specifically, the sufficient size of the bowl portion 12) is not impaired, while the space adjacent to the protruding portion 11 of the washbasin 10 (conventionally occupied by the counter 20) can be allocated, for example, to the track of the door of the adjacent bathroom. In other words, the space utilization efficiency of the installation space of the washbasin 10 can be improved.

[0042] In particular, according to this embodiment, the washbasin 10 is installed so that it "protrudes" forward from the counter 20, so that its functionality as a washbasin 10 (specifically, the sufficient size of the bowl portion 12) is not impaired, while the space adjacent to the left and right sides of the protruding portion 11 of the washbasin 10 (conventionally occupied by the front end of the counter 20) can be allocated, for example, to the track of the opening and closing door of an adjacent bathroom.

[0043] Furthermore, according to this embodiment, the overflow hole 14 is provided in the protruding portion 11 of the washbasin 10, which makes it easy to ensure a sufficient size for the bowl portion 12, and furthermore, the overflow hole 14 is difficult to see from the user of the washbasin 10, resulting in a highly aesthetic design.

[0044] Furthermore, according to this embodiment, the overflow hole 14 is located above the upper end of the washbasin mounting portion of the counter 20. This allows the overflow hole 14 to be provided in any suitable position.

[0045] Furthermore, according to this embodiment, a recess 16 is provided on the underside of the washbasin 10, facing the upper edge of the apron 22 in the washbasin placement portion of the counter 20. This allows for easy positioning or temporary fixation between the recess 16 and the upper edge of the apron 22 by utilizing the fit or engagement between them.

[0046] Furthermore, according to this embodiment, overflow hole 14 communicates with drain outlet 13 via overflow channel 15, which is formed with a downward slope from protruding portion 11 toward the rear in the front-rear direction. This allows overflow hole 14 to perform its function reliably.

[0047] Furthermore, according to this embodiment, the volume of the overflow channel 15 in the area located within the protruding portion 11 (the area shown by hatching in FIG. 3) is larger than the volume of the area located above the washbasin mounting portion of the counter 20 (the area shown by matte finish in FIG. 3). This makes it possible to effectively prevent backflow in the overflow channel 15.

[0048] Furthermore, according to this embodiment, a throttle portion 15t is formed in the overflow passage 15 midway from the protruding portion 11 side to the rear side in the front-rear direction, which makes it possible to effectively prevent backflow in the overflow passage 15.
