Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described washbasin, at the connecting portion near the curved portion where the bowl portion curves, there is a risk of breakage due to shrinkage during firing of the washbasin or cracking due to heat shock caused by temperature changes in the washbasin. That is, there is room for improvement in suppressing breakage due to stress concentration during firing in the above-described washbasin.

[0005] One aspect of the embodiment aims to provide a washbasin that suppresses breakage due to stress concentration during firing.

Means for Solving the Problems

[0006] A washbasin according to one embodiment comprises a bowl portion, a mounting portion, and a connecting portion. The mounting portion is provided outside the bowl portion and is supported by a mounting base. The connecting portion connects the outer surface of the bowl portion and the inner surface of the mounting portion on the lower side of the bowl portion. The connecting portion comprises a first flat portion, a second flat portion, and a connecting portion. The first flat portion is connected to the inner surface of the mounting portion. The second flat portion is connected to the outer surface of the curved portion of the bowl portion, which is curved in plan view, and is located at a different position in the vertical direction from the first flat portion. The connecting portion connects the first flat portion and the second flat portion.

[0007] This allows the washbasin to reduce the stress on the connection point between the curved part of the bowl and the connecting part if the connecting part shrinks during firing or due to thermal shock. Therefore, the washbasin can be prevented from cracking or other damage caused by stress concentration during firing at the connection point between the curved part of the bowl and the connecting part. By providing a second flat section at the point where it connects to the outer surface of the curved part of the bowl, the design of the bowl can be prevented from being restricted.

[0008] Furthermore, the upper surface of the first flat section is located in a different position vertically from the upper surface of the second flat section.

[0009] As a result, the washbasin can distribute stress generated by the expansion or contraction of air in the internal space formed by the bowl, base, and connecting parts through the connecting parts. Therefore, the washbasin can suppress breakage and other damage caused by stress concentration due to the expansion or contraction of air in the internal space.

[0010] Furthermore, the thickness of the first flat portion in the vertical direction is approximately the same as the thickness of the second flat portion in the vertical direction.

[0011] This makes it possible to suppress the occurrence of cracks in the washbasin due to differences in thickness during firing.

[0012] Furthermore, the connecting section includes a third flat section. The third flat section is connected to the outer surface of the non-curved section of the bowl section. The distance between the first flat section and the second flat section in the vertical direction is longer than the distance between the first flat section and the third flat section in the vertical direction.

[0013] As a result, when shrinkage occurs in the connecting section of the washbasin, the length of the connecting section that connects to the second flat section that connects to the curved section is increased, allowing the deformation caused by shrinkage to be relieved, thereby reducing the stress on the connection point between the curved section of the bowl and the connecting section. Therefore, the washbasin can suppress the occurrence of cracks or other damage due to stress concentration during firing at the connection point between the curved section of the bowl and the connecting section.

[0014] Furthermore, the connecting section includes an inclined section. The inclined section connects the second flat section and the third flat section.

[0015] This makes it possible to suppress the occurrence of cracks or other damage due to stress concentration during firing at the point where the second flat section and the third flat section of the washbasin are connected. [Effects of the Invention]

At least one of the second side wall portion 11b and the third side wall portion 11c may be provided vertically.

[0027] The bowl portion 2 is configured to receive water by the bottom portion 10 and the first side wall portions 11a to the third side wall portions 11c, but is not limited to this. The bowl portion 2 may have a fourth side wall portion at a position opposite the first side wall portion 11a. That is, the bowl portion 2 may have a fourth side wall portion connected to the front end of the bottom portion 10.

[0028] The bowl portion 2 has curved portions 2a to 2d at the four corners of its rectangular shape. The curved portions 2a to 2d are formed to be curved surfaces in a plan view. Curved portion 2a is provided at the connection point between the first side wall portion 11a and the third side wall portion 11c. Curved portion 2b is provided at the connection point between the first side wall portion 11a and the second side wall portion 11b.

[0029] Furthermore, in the following section, a non-curved portion 2e is defined and explained in relation to the curved portions 2a to 2d. The non-curved portion 2e is the part of the substantially rectangular bowl portion 2 that is planar in a plan view. The non-curved portion 2e includes the side wall portion 11 (first side wall portion 11a to third side wall portion 11c).

[0030] The drain section 3 is located below the bowl section 2. Water that flows into the drain outlet 8 flows into the drain section 3. A drain pipe is connected to the drain section 3.

[0031] The peripheral edge portion 4 is provided along the outer circumference of the bowl portion 2. The peripheral edge portion 4 is provided around the entire circumference of the bowl portion 2. The peripheral edge portion 4 is provided so as to extend outward from the upper end of the bowl portion 2. The external shape of the peripheral edge portion 4 is substantially rectangular in plan view. A mounting hole 4a is formed in the peripheral edge portion 4 to which the water outlet of the faucet device is attached. The mounting hole 4a is formed in the peripheral edge portion 4 that extends rearward from the first side wall portion 11a.

[0032] The mounting portion 5 extends downward from the outer peripheral end of the peripheral portion 4. The mounting portion 5 is provided along the outer circumference of the peripheral portion 4. The mounting portion 5 can be provided and screwed around the entire circumference of the peripheral portion 4. In plan view, the mounting portion 5 is a substantially rectangular frame. The lower surface 5a of the mounting portion 5 is in contact with the counter 40. That is, the lower surface 5a of the mounting portion 5 is a contact surface that is in contact with the counter 40. The mounting portion 5 is supported by the counter 40.

[0033] The connecting portion 6 connects the outer surface 12 of the bowl portion 2 and the inner surface 5b of the mounting portion 5 on the lower side of the bowl portion 2. The connecting portion 6 is provided above the lower surface 5a of the mounting portion 5. The washbasin 1 has an internal space 9 enclosed by the connecting portion 6, the bowl portion 2, the peripheral portion 4, and the mounting portion 5. The connecting portion 6 includes a first flat portion 20, a second flat portion 21, a third flat portion 22, a connecting portion 23, and an inclined portion 24.

[0034] The first flat portion 20 is connected to the inner surface 5b of the mounting portion 5. The first flat portion 20 is provided so as to extend horizontally from the inner surface 5b of the mounting portion 5 toward the bowl portion 2. The first flat portion 20 may also be provided so as to be inclined with respect to the horizontal direction from the inner surface 5b of the mounting portion 5.

[0035] The second flat section 21 is connected to a part of the outer surface 12 of the bowl section 2. The second flat section 21 is connected to the outer surface 12 of the curved sections 2a and 2b of the bowl section 2. The second flat section 21 is provided so as to extend horizontally from the outer surface 12 of the bowl section 2 toward the mounting section 5. The second flat section 21 may be provided so as to be inclined with respect to the horizontal direction from the outer surface 12 of the bowl section 2. The second flat section 21 is provided in two locations so as to be connected to the outer surface 12 of the curved sections 2a and 2b of the bowl section 2, but is not limited to this. The second flat section 21 may be provided in four locations so as to be connected to the outer surface 12 of the curved sections 2c and 2d of the bowl section 2.

[0036] The second flat section 21 is located at a different vertical position from the first flat section 20. The second flat section 21 is located above the first flat section 20. The upper surface 21a of the second flat section 21 is located at a different vertical position from the upper surface 20a of the first flat section 20. The lower surface 21b of the second flat section 21 is located at a different vertical position from the lower surface 20b of the first flat section 20. The thickness of the second flat section 21 in the vertical direction is approximately the same as that of the first flat section 20 in the vertical direction.

[0037] The third flat section 22 is connected to a part of the outer surface 12 of the bowl section 2. The third flat section 22 is connected to the outer surface 12 of the non-curved section 2e of the bowl section 2. The third flat section 22 is provided so as to extend horizontally from the outer surface 12 of the bowl section 2, for example. For example, the third flat section 22 is provided so as to be coplanar with the first flat section 20. The third flat section 22 may be provided so as to be inclined with respect to the horizontal direction from the outer surface 12 of the bowl section 2.

[0038] The distance between the first flat section 20 and the second flat section 21 in the vertical direction is longer than the distance between the first flat section 20 and the third flat section 22 in the vertical direction. That is, the amount of protrusion of the second flat section 21 relative to the first flat section 20 is greater than the amount of protrusion of the third flat section 22 relative to the first flat section 20. When the first flat section 20 and the third flat section 22 are provided to be on the same plane, the distance between the first flat section 20 and the third flat section 22 is zero. The thickness of the third flat section 22 in the vertical direction is approximately the same as the thickness of the first flat section 20 in the vertical direction. When the ceramic material such as the slurry of the washbasin 1 is deposited in the mold, the thickness is formed at a generally uniform speed, so that the thickness of the third flat section 22 in the vertical direction and the thickness of the first flat section 20 in the vertical direction can be made approximately the same.

[0039] The connecting portion 23 connects the first flat portion 20 and the second flat portion 21. The connecting portion 23 connects the end of the first flat portion 20 on the bowl portion 2 side and the end of the second flat portion 21 on the mounting portion 5 side. The connecting portion 23 is provided so as to extend along the vertical direction, for example. That is, the connecting portion 6 has a stepped portion that protrudes vertically to the outside of the curved portions 2a and 2b of the bowl portion 2, by the first flat portion 20, the connecting portion 23, and the second flat portion 21. The connecting portion 23 may be provided at an inclination with respect to the vertical direction. The connecting portion 23 also connects the inclined portion 24 and the first flat portion 20.

[0040] The inclined section 24 connects the second flat section 21 and the third flat section 22. The inclined section 24 connects the end of the third flat section 22 and the end of the second flat section 21. The inclined section 24 is provided so as to be inclined diagonally upward from the third flat section 22 to the second flat section 21.

[0041] In the comparative example washbasin 100, for example, as shown in Figure 6, the outer surface 102a of the curved portion 102 of the bowl portion 101 and the inner surface 103a of the mounting portion 103 are connected by a single flat portion 104. Figure 6 is a cross-section of the washbasin 100 of the comparative example near the curved portion 102 of the bowl portion 101. In the comparative example washbasin 100, due to shrinkage during firing of the washbasin 100, the straight-shaped flat portion 104 has no part to release the resulting shrinkage deformation, and there is a risk of cracking between it and the mounting portion 103. Also, in the comparative example washbasin 100, if hot water is placed in the bowl portion 101, there is a risk of cracking between the flat portion 104 and the mounting portion 103 due to thermal shock. "Cracking" or "breaking" occurs, for example, when stress due to shrinkage of the flat portion 104 is applied to the connection point between the flat portion 104 and the mounting portion 103. In particular, "breaks" and "crackings" are prone to occur near the curved portion 102 of the bowl portion 101. "Breaks" are mainly caused by tensile fracture due to shrinkage during firing, while "crackings" are caused by bending fracture resulting from deformation caused by shrinkage due to thermal shock.

[0042] In the washbasin 1 according to this embodiment, the positions of the first flat section 20 and the second flat section 21 are different in the vertical direction, and the first flat section 20 and the second flat section 21 are connected by a connecting section 23. As a result, as shown in Figure 7, the washbasin 1 can receive the stress generated by the shrinkage of the first flat section 20 through the connecting section 23. Therefore, the washbasin 1 can reduce stress by releasing the shrinkage applied to the connection point between the second flat section 21 and the outer surface 12 of the bowl section 2 as deformation, for example, during firing. In other words, the washbasin 1 can distribute the stress generated when the connecting section 6 shrinks through the connecting section 23, thereby reducing the stress applied to the connection point between the second flat section 21 and the outer surface 12 of the bowl section 2. The washbasin 1 can reduce the stress applied to the connection point between the connecting section 6 and the outer surface 12 of the curved sections 2a and 2b of the bowl section 2. Figure 7 is a diagram showing the stress generated by the shrinkage of the connecting section 6 in the washbasin 1 according to this embodiment.

[0043] The washbasin 1 comprises a bowl portion 2, a mounting portion 5, and a connecting portion 6. The mounting portion 5 is located outside the bowl portion 2 and is supported by the counter 40. The connecting portion 6 connects the outer surface 12 of the bowl portion 2 and the inner surface 5b of the mounting portion 5 on the underside of the bowl portion 2. The connecting portion 6 comprises a first flat portion 20, a second flat portion 21, and a connecting portion 23. The first flat portion 20 is connected to the inner surface 5b of the mounting portion 5. The second flat portion 21 is connected to the outer surface 12 of the curved portions 2a and 2b of the bowl portion 2, which are curved in plan view, and is located in a different position vertically from the first flat portion 20. The connecting portion 23 connects the first flat portion 20 and the second flat portion 21.

[0044] As a result, if the connecting part 6 shrinks during firing or due to thermal shock, the connecting part 23 can reduce the stress on the connection point between the curved parts 2a and 2b of the bowl part 2 and the connecting part 6. Therefore, the washbasin 1 can suppress the occurrence of cracks or other damage due to stress concentration during firing at the connection point between the curved parts 2a and 2b of the bowl part 2 and the connecting part 6.

[0045] Furthermore, unlike the washbasin 1 according to the embodiment, if the second flat portion is provided around the entire circumference of the bowl portion of the washbasin, it may restrict the design of the bowl portion. In the washbasin 1 according to the embodiment, the restriction on the design of the bowl portion 2 can be suppressed by providing the second flat portion 21 at the location connected to the outer surface 12 of the curved portions 2a and 2b of the bowl portion 2.

[0046] The upper surface 21a of the second flat portion 21 is located in a different position in the vertical direction from the upper surface 20a of the first flat portion 20.

[0047] As a result, the washbasin 1 can distribute the stress generated by the expansion or contraction of the air in the internal space 9 through the connecting part 23. Therefore, the washbasin 1 can suppress breakage and other damage caused by stress concentration due to the expansion or contraction of the air in the internal space 9.

[0048] The thickness of the first flat portion 20 in the vertical direction is approximately the same as the thickness of the second flat portion 21 in the vertical direction.

[0049] This makes it possible to suppress the occurrence of cracks in the washbasin 1 due to differences in thickness during firing.

[0050] The connecting portion 6 includes a third flat portion 22. The third flat portion 22 is connected to the outer surface 12 of the non-curved portion 2e of the bowl portion 2. The distance between the first flat portion 20 and the second flat portion 21 in the vertical direction is longer than the distance between the first flat portion 20 and the third flat portion 22 in the vertical direction.

[0051] As a result, when shrinkage occurs in the connecting portion 6 of the washbasin 1, the length of the connecting portion 23 connected to the second flat portion 21 that connects to the curved portions 2a and 2b is increased, allowing the deformation caused by shrinkage to be relieved, thereby reducing the stress on the connection point between the curved portions 2a and 2b of the bowl portion 2 and the connecting portion 6. Therefore, the washbasin 1 can suppress the occurrence of cracks or other damage due to stress concentration during firing at the connection point between the curved portions 2a and 2b of the bowl portion 2 and the connecting portion 6.

[0052] The connecting section 6 includes an inclined section 24. The inclined section 24 connects the second flat section 21 and the third flat section 22.

[0053] As a result, the washbasin 1 can suppress the occurrence of cracks or other damage due to stress concentration during firing at the point where the second flat section 21 and the third flat section 22 are connected.

[0054] In the modified washbasin 1, as shown in Figure 8, the second flat portion 21 is provided below the first flat portion 20. Figure 8 is a cross-sectional view showing the positions of the first flat portion 20 and the second flat portion 21 of the modified washbasin 1. Figure 8 is a cross-sectional view of the modified washbasin 1 corresponding to Figure 4. The modified washbasin 1 can suppress deterioration, similar to the above embodiment. Furthermore, the modified washbasin 1 can suppress limitations on the design of the bowl portion 2, similar to the above embodiment.

[0055] In the modified washbasin 1, the position of the third flat portion 22 in the vertical direction may be different from that of the first flat portion 20. The third flat portion 22 is provided in the vertical direction at a position between the first flat portion 20 and the second flat portion 21.

[0056] In the washbasin 1 according to this embodiment, the bowl portion 2 is substantially rectangular in plan view, but is not limited to this. The bowl portion 2 may be elliptical or circular in plan view. The connecting portion 6 described above, namely the first flat portion 20, the second flat portion 21, and the connecting portion 23, are provided, for example, at the location where the bowl portion 2 curves in plan view.

[0057] Further effects and modifications can be readily derived by those skilled in the art. Therefore, broader aspects of the present invention are not limited to the specific details and representative embodiments expressed and described above. Accordingly, various modifications are possible without departing from the spirit or scope of the overall concept of the invention as defined by the appended claims and their equivalents.
