Description

  The present invention relates to a bathtub.

  A conventional general bathtub 1 ′ has a bathtub body 2 in which a substantially vertical side wall 21 is erected from the periphery of a substantially horizontal bottom wall 20, as shown in FIG. A bathing space 4 having a substantially rectangular parallelepiped shape surrounded by 21 is formed. However, this substantially rectangular rectangular bathing space 4 has many unused spaces (cross-hatched portions in the figure) that will be filled with bathing water that does not serve for effective use, such as warming by touching the bather. In other words, extra water that was not used for bathing was accumulated.

  Thus, for example, as in Patent Document 1, a bathing space imitating the shape of a human body of a bather is formed by a bathtub body and a bathtub lid, and a non-use space that generates waste water is suppressed to enhance a water-saving effect. Has been developed.

However, when there are multiple bathers who use a bathtub such as using one bathtub in a family, the body shape is different for each bather, and a certain amount of bath water is supplied to the bathing space. In the bathtub of Document 1, bathers with large body types may overflow bath water, and bathers with small body types may not be immersed in the bath water. That is, in the bathtub disclosed in Patent Document 1, it is difficult to ensure a comfortable bathing and water-saving effect even for bathers of different body types.

  This invention is made | formed in view of said point, The place made into the objective is providing the bathtub which can ensure a comfortable bathing and water-saving effect even if it is a bather of a different body shape. It is to be an issue.

  In order to solve the above-mentioned problem, in the bathtub according to claim 1, the relief opening 7 is provided in the bathtub lid 3 that opens and closes the upper opening 2 a of the bathtub body 2, and the bathtub lid 3 opens the upper opening 2 a of the bathtub body 2. When closed, a bathing space 4 for bathing the bather is formed between the bathtub lid 3 and the bath body 2, and the bathing space 4 passes above the upper opening 2 a of the bather body 2 through the escape opening 7. It is possible for the bather to take a bath in a bathing posture so as to escape the part to the outside, and the bather in the above bathing posture by the uneven portion 5 provided on at least one of the lower surface of the bathtub lid 3 and the inner surface of the bathtub body 2. It is formed in a shape imitating a part in the bathing space 4, and a bath water supply hole 6 is formed in the bathtub lid 3 so as to communicate the bathing space 4 and the outside.

  According to this, since the bathing space 4 is formed in a shape imitating the bathing site of the bather in the predetermined bathing posture (the site in the bathing space 4), the bathing space 4 where the bather is located is wasted. The formation of unused space for generating water can be suppressed, and a water saving effect can be secured. Further, a bath water replenishing hole 6 is drilled in the bathtub lid 3 so as to communicate the bathing space 4 with the outside. Since it is provided, the bathing space 4 can be appropriately supplied with an amount of bath water suitable for the body shape of the bather from the outside through the bath water replenishment hole 6, for example, even in the case of a bather with a small body shape, All the parts in the space 4) can be soaked in the bath water, that is, a comfortable bathing can be ensured even for bathers of different body types.

  In this invention, even if it is a bather of a different body type, it has the advantage that a comfortable bathing and the water-saving effect can be ensured.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 4, the bathtub 1 of this example includes a bathtub main body 2 that is installed adjacent to the washing place 11 of the bathroom 10, and a bathtub lid 3 that opens and closes the upper opening 2 a of the bathtub main body 2. The bathtub body 2 is configured by standing a side wall 21 from the periphery of the bottom wall 20, and the upper opening 2 a is configured by being surrounded by the upper end of the side wall 21. The bathtub 1 is formed in a substantially rectangular shape in a plan view or a so-called elongated shape in a plan view in an elliptical shape, and a bather takes a bath so that his / her body is aligned with the longitudinal direction of the bathtub 1. For convenience, a portion on one end side of the bathtub 1 where the bather's head is located is referred to as a head-side end portion (A in the figure), and a portion on the other end side portion is the foot-side end where the bather's foot tip is located. Part (B in the figure).

  In this example, the bathtub main body 2 is disposed so that the outer surface of the end portion on the foot side is along the wall 12 of the bathroom 10. As shown in FIG. 2, the bathtub lid 3 is attached to the wall 12 of the bathroom 10, along which the outer surface of the foot side end of the bathtub main body 2 extends along the hinge 13 via the hinge 13. The part side end part can be raised and lowered freely with the foot side end part as a rotation center. And this bathtub lid 3 is the state in which the peripheral part 31 was mounted in the upper end surface of the side wall 21 of the bathtub main body 2, The upper opening 2a of the bathtub main body 2 by the lid main body part 30 enclosed by this peripheral part 31 Is to be blocked.

  The bather takes a bath in the bathing space 4 inside the bathtub body 2, but can bathe even when the upper opening 2 a of the bathtub body 2 is closed by the bathtub lid 3 as shown in FIG. 1. That is, at the end on the head side of the bathtub lid 3, as shown in FIG. 4, a notch-opening shape is provided for letting a portion above the upper opening 2 a of the bathtub body 2 in the bathing posture in the bathing posture to escape to the outside. A relief opening 7 is formed. The escape opening 7 communicates the bathing space 4 and the outside of the bathtub 1 with the upper opening 2a of the bathtub body 2 closed by the bathtub lid 3, and has a size that allows at least the neck of the bather to be inserted. Although it can be formed in the opening, as shown in FIG. 5, for example, it is formed in an opening large enough to allow the bather's chest to be inserted, and the armrest portion 14 is used to place the bather's arm over the upper edge of the opening. So that the comfort of the bathing posture may be improved. The armrest portion 14 shown in FIG. 5 includes a concave step portion 32 that is recessed from the upper surface of the bathtub lid 3, and a water gradient 32 a toward the escape opening 7 is formed on the upper surface of the concave step portion 32. The bath water dripping from the bather's arm is allowed to flow from the escape opening 7 to the bathing space 4 without spreading over the entire upper surface of the bathtub lid 3.

  By the way, in the bathtub 1 of this example, the bather is allowed to bathe in a state where the upper opening 2a of the bathtub body 2 is closed with the bathtub lid 3 as described above, that is, the bathtub lid 3 is opened upward of the bathtub body 2. A bathing space 4 is formed between the bath body 2 and the bath lid 3 when the bath 2a is closed. This bathing space 4 is a bathing posture of a bather who bathes in a state in which the upper opening 2 a of the bathtub body 2 is closed by the bathtub lid 3 by the uneven portion 5 provided on the inner surface of the bathtub body 2 and the lower surface of the bathtub lid 3 ( Specifically, it is formed in a shape imitating a bather's bathing space 4 in a bathing position. As shown in FIG. 1, the bathing posture of the bather in the bathtub 1 of this example is such that the front side of the body is directed upward and the back side of the body is directed downward, and the head is moved from the bathing space 4. It goes out of the bathtub 1 through the escape opening 7 and leans on the upper end of the side wall 21a at the head side end of the bathtub body 2 so that the upper limb is slightly turned up and the buttock is placed on the bottom wall of the bathtub body 2 20 is placed at a position slightly closer to the head side end, the knee is bent to the extent that it does not become cramped, and the foot portion is connected to the bottom wall 20 of the bathtub body 2 and the side wall 21b of the foot side end portion. It is a posture to place it on the corner part of.

  In the present example, the uneven portion 5 includes a back side spacer 50 and a foot side spacer 51 provided on the inner surface of the bathtub body 2 and a human body surface side spacer 52 provided on the lower surface of the bathtub lid 3 as shown in FIG. Is done. The back-side spacer 50 is formed from the bottom wall 20 of the bathtub body 2 on the head side to the side wall 21a at the head-side end of the bathtub body 2 with respect to the buttocks placement area 20a on which the bather's buttocks in a bathing posture are placed. The protruding surface is formed so as to incline downward from the head side end portion side toward the foot tip side end portion side. The back side spacer 50 has a protruding surface along the back of a bather in a bathing posture.

  Moreover, the foot side spacer 51 is the foot side end of the bathtub main body 2 from the part of the bottom wall 20 of the bathtub main body 2 on the foot side relative to the buttocks placement area 20a where the buttocks of the bather in the bathing posture are placed. The protruding surface is formed so as to incline downward from the toe side end portion side toward the head side end portion side at a predetermined height position of the protruding surface. The other end of the pair of foot insertion holes 53 opened so that one end is opened at the corner portion of the bottom wall 20 of the bathtub body 2 and the side wall 21b of the foot tip side end portion. As shown in FIG. 1, the foot side spacer 51 has a lower region 51 a along the back of the thigh of a bather in a bathing posture than the opening position of the foot insertion hole 53 on the projecting surface. The inner surface of the foot insertion hole 53 for inserting the bather's lower knee is located along the lower part of the bather's knee. According to the back-side spacer 50 and the foot-side spacer 51, the bathing space 4 can be shaped to resemble the back shape of a bather in a bathing posture.

  Moreover, the human body surface side spacer 52 is projectedly provided in the site | part of the cover main-body part 30 of the lower surface of the bathtub lid 3, and the protrusion surface is a foot tip side in order from the foot side edge part side to the head side edge part side. A first downward inclined surface 52a inclined downward from the end side toward the head side end portion side, and a first upward inclined surface 52b inclined upward from the lower end of the first downward inclined surface 52a toward the head side end portion side. The second downward inclined surface 52c inclined downward from the upper end of the first upward inclined surface 52b toward the head side end, and the upward inclined toward the head side end from the lower end of the second downward inclined surface 52c. The second upward inclined surface 52d is formed continuously. When the bathtub lid 3 closes the upper opening 2 a of the bathtub body 2, the first upward inclined surface 52 b of the human body surface side spacer 52 is the opening position of the foot insertion hole 53 on the protruding surface of the foot side spacer 51 as shown in FIG. 1. It is arranged to face the upper area 51b. Further, at this time, the first ascending inclined surface 52b and the second descending inclined surface 52c are arranged along the surface of the thigh from the knee of the bather in the bathing posture, and the second ascending inclined surface 52d is in the bathing posture. It is made to be along the surface of a bather's upper limb. According to this human body surface side spacer 52, the bathing space 4 can be made to have a shape imitating at least the surface shape of the bather in the bathing posture.

  Thus, when the upper opening 2a of the bathtub body 2 is closed with the bathtub lid 3, the bathing space 4 is substantially shaped like a human body of a bather in a bathing posture by the concavo-convex portion 5 provided on the bathtub body 2 and the bathtub lid 3. In other words, it is possible to suppress the formation of a non-use space that generates waste water with respect to the bathing space 4 where the bather is located, and a high water-saving effect is ensured. It is. In addition, in order to make the bathing space 4 into a shape imitating a bather in a bathing posture, it can be formed only by using the concavo-convex portion 5 of either the bathtub body 2 or the bathtub lid 3, thereby achieving a water-saving effect. Needless to say, you can.

  In addition, the said uneven | corrugated | grooved part 5 has self-shape-retaining property at least, for example, makes the same material as the bathtub main body 2 and the bathtub lid 3, and is formed integrally at the time of manufacture of the bathtub main body 2 and the bathtub lid 3, and manufacture of the bathtub 1 The unevenness part 5 may be separated from the bathtub main body 2 and the bathtub lid 3, and may be bonded to and integrated with the bathtub main body 2 and the bathtub lid 3. In the latter case, the concavo-convex portion 5 can be formed of a material different from that of the bathtub body 2 and the bathtub lid 3, for example, the concavo-convex portion 5 has some elasticity so that it can absorb an impact when it hits a bather. It can also be made of an elastic material such as rubber.

  By the way, in the bathtub lid 3 of this example, when the upper opening 2a of the bathtub main body 2 is closed by the bathtub lid 3, a bath water replenishing hole 6 is formed to communicate the bathing space 4 and the outside of the bathtub 1. Yes. Specifically, in this example, as shown in FIG. 4, the bath water replenishment hole 6 includes a portion of the bathtub lid 3 that is closer to the washing place and closer to the head side end, and a portion closer to the washing place and closer to the foot side. The bath water supply holes 6 are opened and closed freely by a removable lid 8. More specifically, the former bath water replenishment hole 6a is provided at a position where the water discharged from the shower 15 can be easily poured when the washing work such as shampooing is performed, and the second surface 52 of the human body surface side spacer 52 as shown in FIG. One end of the upward inclined surface 52d is opened to communicate with the bathing space 4. The latter bath water replenishment hole 6b is provided at a position where water discharged from the currant 16 provided on the wall 12 of the bathroom 10 can be easily poured. As shown in FIG. One end is open to the downward inclined surface 52a, and the first upward inclined surface 52b of the human body surface side spacer 52 and the upper region 51b above the opening position of the foot insertion hole 53 on the protruding surface of the foot side spacer 51 are opposed to each other. It communicates with the bathing space 4 through the gap.

  Thus, since the bath water replenishment hole 6 is formed in the bathtub lid 3 so as to communicate the bathing space 4 with the outside, the bath water replenishment hole 6 can be externally connected to the body shape of the bather. Bath water can be appropriately supplied to the bathing space 4. Therefore, for example, even in the case of a bather having a small body shape, the bather replenishes the bathing space 4 through the bathing water replenishment hole 6, whereby the bathing site (the site in the bathing space 4). All of the above can be soaked in bath water and the bathtub 1 can be used comfortably. That is, a comfortable bathing can be secured even for bathers of different body types.

  In the above embodiment, the bathtub lid 3 is attached to the foot 12 side end of the bathtub body 2 while its foot side end is attached to the wall 12 of the bathroom 10 so that it can be tilted up and down. It may be attached in a freely tiltable manner, and does not include a connecting member such as the hinge 13 for the bathtub body 2 or the wall of the bathtub 1 like a general bathtub lid, and can be attached to and detached from the separate bathtub body 2. It may be used.
