Description

[Technical Field]

[0001] The present disclosure relates to a washbasin configuration. [Background technology]

[0002] A washbasin includes a faucet and a washbasin. In a wall-mounted washbasin, the washbasin protrudes horizontally from the wall. In wall-mounted washbasins installed in narrow living spaces such as ships and vehicles, the washbasin protruding from the wall narrows the living space. To address this issue, some washbasins are designed with a flip-up and pivoting washbasin that can be stored in an upright position along the wall. Patent Document 1 discloses this type of washbasin.

[0003] The washbasin disclosed in Patent Document 1 includes a platform that forms a washbasin below the faucet, and the platform has a bottom and a peripheral edge that surrounds the bottom. The platform is attached to the wall so as to be rotatable around one side, and is movable between two positions: a storage position in which the bottom is approximately vertical and protrudes only slightly from the wall, and a use position in which the bottom is approximately horizontal and protrudes from the wall.

[0004] [Patent Document 1] Special Publication No. 2020-516368 Summary of the Invention [Problem to be solved by the invention]

[0005] The washbasin in a bathroom sink is used not only to catch water from the faucet, but also to store water. In a washbasin equipped with a washbasin that is rotatably attached to the wall, as in Patent Document 1, it is desirable for the washbasin to be shallow in order to reduce the amount by which the washbasin protrudes from the wall when in the retracted position. On the other hand, when storing water in the washbasin, a washbasin with a certain depth is more practical than a shallow one.

[0006] The present disclosure has been made in consideration of the above circumstances, and its purpose is to propose a wall-mounted washbasin that has a reduced amount of protrusion from the wall when stored and is equipped with a washbasin that is deep enough to be highly practical when in use. [Means for solving the problem]

[0007] In order to solve the above problem, a washbasin according to one aspect of the present disclosure includes: A wall-mounted washbasin, The faucet and a washbasin disposed below the faucet; The washbasin has a frame, a bottom having an outer shape that fits inside the frame, and an extension / contraction section that connects the frame and the bottom in the depth direction of the washbasin and is expandable / contractable in the depth direction, and is characterized in that it can be rotated around a rotation axis parallel to the wall between a use position in which the frame is in a horizontal position and a storage position in which the frame is in a vertical position. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to provide a wall-mounted washbasin that has a reduced amount of protrusion from the wall when stored and is equipped with a washbasin that is deep enough to be highly practical when in use. [Brief explanation of the drawings]

[0010] [First embodiment] Next, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a front view of a washbasin 1 according to a first embodiment of the present disclosure in use, and Fig. 2 is a cross-sectional view taken along the line II-II in Fig. 1 showing the washbasin 1 in use. As shown in Figs. 1 and 2, the washbasin 1 according to the first embodiment is a "wall-mounted" type that is attached to a wall 10, and includes a faucet 2, a washbasin 3, a drainage section 4, and a casing 5. The washbasin 1 may be attached to the surface of the wall 10, or may be embedded in the wall 10 so as to be flush with the surface of the wall 10.

[0011] The casing 5 includes a gate-shaped outer frame 51 and a back plate 52. The casing 5 is attached to the wall 10 so that the back plate 52 is parallel to the wall 10.

[0012] A faucet base 21 that supports the faucet 2 is provided inside the outer frame 51 of the casing 5. The faucet base 21 is supported by the casing 5, but may also be supported by the drainage section 4.

[0013] The faucet 2 comprises a faucet body 22 and a lever handle 23, which is the operating tool for the faucet 2. The faucet body 22 has a nozzle 24 that forms a flow path and a valve that opens and closes the flow path. The nozzle 24 is connected to a water supply pipe. The valve is opened and closed by operating the lever handle 23, and when the valve is opened, water supplied from the water supply pipe flows out from the outlet of the nozzle 24.

[0014] The faucet body 22 is attached to the faucet base 21 so that it can rotate about a rotation axis that extends in the vertical direction. The faucet 2, i.e., the faucet body 22 and lever handle 23, are movable between a storage position where they are housed inside the outer frame 51 and a use position where parts such as the nozzle 24 protrude from the outer frame 51 in a direction away from the wall 10.

[0015] The drainage section 4 is disposed below the casing 5. The amount by which the drainage section 4 protrudes from the wall 10 is preferably equal to or less than the amount by which the outer frame 51 of the casing 5 protrudes from the wall 10. The drainage section 4 has a water collection port 41 that opens upward. The water collection port 41 is the entrance to a water collection channel 42, the cross-sectional area of ​​which gradually decreases downward. The water collection channel 42 is connected to a drain pipe. Water that flows into the water collection port 41 flows downward through the water collection channel 42 and out into the drain pipe. Note that if the washbasin 1 is attached to the wall 10 of a space where water may be poured onto the floor, such as a bathroom, the drainage section 4 may be omitted and the water that has accumulated in the washbasin 3 may be drained onto the floor.

[0016] The washbasin 3 has a frame 31, a bottom 32, and an expandable portion 33. The frame 31 is rectangular. However, the frame 31 may also be circular or elliptical. The frame 31 is supported by the casing 5 so as to be rotatable in the vertical direction around a rotation axis substantially parallel to the surface of the wall 10. However, the frame 31 may also be supported by the drainage portion 4. The washbasin 3 is rotatable between a use position in which the frame 31 protrudes substantially horizontally from the wall 10, and a storage position in which the frame 31 is rotatable upward from the use position around the rotation axis so that the frame 31 is oriented vertically substantially parallel to the wall 10. It is preferable that the washbasin 3 be able to maintain its position in both the use position and the storage position.

[0017] The bottom 32 has an outer shape that fits inside the frame 31 and serves as a tray for water. The lower edge of the frame 31 and the outer edge of the bottom 32 are connected by an expandable portion 33. The expandable portion 33 has a tubular shape that is expandable in the depth direction X of the washbasin 3. When the expandable portion 33 is expanded, the frame 31 and the bottom 32 are spaced apart in the depth direction X. When the expandable portion 33 is contracted to its minimum, the bottom 32 is preferably close to the lower edge of the frame 31 in the depth direction X, or the bottom 32 is contained within the frame 31's space in the depth direction X.

[0018] The expandable portion 33 has, for example, a bellows structure. The bellows-structured expandable portion 33 is composed of a flexible layer and a hard layer aligned in the depth direction X. The flexible layer is elastically deformable, while the hard layer is harder and less elastically deformable than the flexible layer. For example, a two-stage bellows-structured expandable portion 33 is composed of a first flexible layer 36, a hard layer 37, and a second flexible layer 38 aligned in the depth direction X between the frame portion 31 and the bottom portion 32. Note that the frame portion 31 is preferably resistant to elastic deformation, while the bottom portion 32 may be elastically deformable or not. As shown in FIG. 3 , when the bottom portion 32 is pushed up toward the frame portion 31, the first flexible layer 36 and the second flexible layer 38 elastically deform, allowing the expandable portion 33 and the bottom portion 32 to fit inside the frame portion 31. Once inside the frame portion 31, the expandable portion 33 is folded into a bellows shape. In this way, the expandable portion 33 and the bottom portion 32 fit inside the frame portion 31, and the washbasin 3 can be contracted in the depth direction X. In addition, by unfolding the expandable portion 33 folded like an accordion, the washbasin 3 can be extended in the depth direction X.

[0019] The number of stages in the bellows structure is not limited to two, but may be three or more, or may be one. For example, the expandable portion 33 of a one-stage bellows structure is made up of a flexible layer connecting the hard frame portion 31 and the bottom portion 32. When the bottom portion 32 is pushed up, the flexible layer elastically deforms, allowing the bottom portion 32 to fit inside the frame portion 31.

[0020] The telescopic portion 33 is not limited to a bellows structure. For example, the telescopic portion 33 may have a sleeve structure. Figure 5 is a cross-sectional view of a washbasin 3 having a sleeve structure. As shown in Figure 5, the telescopic portion 33 of the sleeve structure is composed of an outer sleeve 45 and an inner sleeve 46. The outer sleeve 45 is inserted into the frame 31, the inner sleeve 46 is inserted into the outer sleeve 45, and the bottom 32 is inserted into the inner sleeve 46. Locking portions for preventing dislodgment are provided between the frame 31 and the outer sleeve 45, between the outer sleeve 45 and the inner sleeve 46, and between the inner sleeve 46 and the bottom 32, and gaskets for preventing water leakage are also provided. The dimensions of the outer sleeve 45 and the inner sleeve 46 in the depth direction X are preferably equal to or smaller than the dimension of the frame 31 in the depth direction X. The washbasin 3 consisting of the frame 31, the outer sleeve 45, the inner sleeve 46, and the bottom 32 can telescopically expand and contract in the depth direction X. As shown in FIG. 6, the washbasin 3 can be contracted in the depth direction X by stacking the frame portion 31, the outer sleeve 45, the inner sleeve 46, and the bottom portion 32.

[0021] Here, we will explain how to use the washbasin 1 configured as described above. Figure 4 is a front view of the washbasin 1 in the stored state. As shown in Figures 3 and 4, in the stored state of the washbasin 1, the faucet 2 is in the stored position, the washbasin 3 is also in the stored position, and the washbasin 3 is retracted in the depth direction X. The faucet 2 is housed inside the washbasin 3, and the washbasin 3 is housed inside the outer frame 51 of the casing 5.

[0022] When the washbasin 3 is rotated downward from the stored position to the use position from the washbasin 1 in the stored state, the extension part 33 is unfolded to extend the washbasin 3 in the depth direction X, and the faucet 2 is rotated from the stored position to the use position, the washbasin 1 is in the use state as shown in Figures 1 and 2.

[0023] When the washbasin 1 is in use, the depth of the washbasin 3 is greater than the dimension of the frame 31 in the depth direction X, giving the washbasin 3 a practical depth. This allows the washbasin 3 to hold enough water for washing one's face and dishes. To drain the water accumulated in the washbasin 3, the washbasin 3 is rotated upward from the use position. As the washbasin 3 tilts toward the water collection port 41 of the drainage unit 4, the water accumulated in the washbasin 3 flows out of the washbasin 3, through the water collection port 41 into the water collection channel 42, and is then discharged from the water collection channel 42 into the drain pipe. Here, by pushing the bottom 32 of the washbasin 3 into the frame 31, water can be drained from the washbasin 3.

[0024] When the faucet 2 is rotated from the use position to the storage position in the washbasin 1 in use, the washbasin 3 is retracted in the depth direction X, and the washbasin 3 is rotated upward from the use position to the storage position, the washbasin 1 enters the storage state. As shown in Figures 3 and 4, in the storage state, the frame 31 of the washbasin 3 is in a vertical position standing along the wall 10, and the washbasin 3 is retracted in the depth direction X, which reduces the amount of protrusion of the washbasin 3 from the wall 10. This reduces the amount of protrusion of the washbasin 1 as a whole from the wall 10.

[0025] Second Embodiment Next, a second embodiment will be described. Fig. 7 is a side view of a washbasin 1A according to the second embodiment in use, and Fig. 8 is a cross-sectional view taken along the line VIII-VIII in Fig. 7, illustrating how to store the washbasin 3. As shown in Figs. 7 and 8, the washbasin 1A according to the second embodiment does not include the drainage section 4, as compared to the washbasin 1 according to the first embodiment. The washbasin 1A according to the second embodiment is attached to a wall 10 of a space where water may be poured onto the floor, such as a bathroom.

[0026] The washbasin 1A according to the second embodiment comprises a faucet 2, a washbasin 3, and a casing 5. The faucet 2 and casing 5 of the washbasin 1A according to the second embodiment have substantially the same structure as those of the washbasin 1 according to the first embodiment. Therefore, a detailed description of the faucet 2 and casing 5 will be omitted, and reference will be made to the description of the first embodiment.

[0027] The washbasin 3 of the washbasin 1A according to the second embodiment has substantially the same structure as that of the washbasin 1 according to the first embodiment, except for the storage position. Therefore, detailed explanations other than the storage position of the washbasin 3 will be omitted by referring to the explanation of the first embodiment. The washbasin 3 is rotatable between a use position in which the frame 31 is in a horizontal position protruding substantially horizontally from the wall 10, and a storage position in which the frame 31 is in a vertical position substantially parallel to the wall 10 by rotating downward from the use position around the rotation axis. It is preferable that the washbasin 3 can maintain its position in both the use position and the storage position.

[0028] In the storage position, the washbasin 3 is in a vertical position with the frame 31 standing along the wall 10, and the washbasin 3 is contracted in the depth direction X, thereby limiting the amount by which the washbasin 3 protrudes from the wall 10. When the washbasin 3 is rotated downward from the use position to the storage position, the water collected in the washbasin 3 is drained downward due to the tilt of the washbasin 3. In this way, in a washbasin 1A that is attached to the wall 10 of a space where water may be poured onto the floor, such as a bathroom, the drainage part 4 can be omitted, resulting in a simple configuration.
