However, the prior art has the following problems. The tub described in Patent Document 1 is attached to the wall surface in a state where the bottom wall is in contact with the wall surface. Therefore, the air permeability between the bottom wall and the wall surface is poor, and dirt and mold are likely to occur on the outside of the bottom wall. In addition, the cost is high because a magnet is required. Further, the tubs described in Patent Documents 2 and 3 require an S-shaped hook for hooking on a towel rack, which is not easy to use. Further, in the tub described in Patent Document 3, the handle protruding from the upper surface of the peripheral wall was an obstacle when washing the face and the like. Therefore, there is room for improving the draining performance and usability of the conventional tub.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a hot water tub having good draining performance and usability.

One aspect of the present invention has the following configuration. (1) The tub is characterized by having a main body portion having a bottom wall and a peripheral wall, and a hook portion integrally provided with the main body portion and directly hooked on a bar attached to the wall surface.

Will be done. The main body suspended from the towel rack forms a gap between the bottom wall and the wall surface to ensure breathability. Therefore, dirt and mold are less likely to occur on the outside of the bottom wall. Further, the tub having the above configuration can be hooked directly on the bar via the hook portion without the S-shaped hook, which is convenient. Furthermore, the hook part is more compact than the U-shaped handle and does not protrude much from the main body part, so it does not get in the way when washing the face. Therefore, according to the above configuration, it is possible to realize a tub with good draining performance and usability.

(2) In the tub described in (1), when the hook portion is directly hooked on the bar, the portion of the peripheral wall at a position facing the portion where the hook portion is provided is the bottom wall. It is preferable that the hook portion is provided on the main body portion so that the opening end portion side located opposite to the above is arranged below the closed end portion side located on the bottom wall side.

When the tub with the above configuration is hung from the bar via the hook portion, the water adhering to the main body portion naturally flows down, and the draining performance is good.

(3) In the tub according to (1) or (2), the peripheral wall includes an arc portion provided in an arc shape and connecting portions connected to both ends of the arc portion, and the main body portion is described as described above. It is preferable that the shape when viewed from the side opposite to the bottom wall has a D shape, and the main body portion stands on its own with the connecting portion facing downward.

The tub having the above configuration has good draining performance because the tub can be made to stand on its own and drained even when there is no towel rack or the towel rack is not used.

(4) In the tub described in (3), the connecting portion includes a first connecting surface located on the bottom wall side, a second connecting surface located on the opposite side of the bottom wall, and the first connecting surface. Has a stepped portion connecting the first connecting surface and the second connecting surface so that is located inside the second connecting surface, and the hook portion is hooked between the first connecting surface and the first connecting surface. It is preferable that a groove is formed.

In the tub having the above configuration, the hook groove of the hook part is formed by using the stepped part provided on the peripheral wall. The hook part does not get in the way when using.

(5) In the tub according to (4), the hook portion is from an end portion of the second connecting surface opposite to the bottom wall toward the bottom wall side, or the bottom wall of the second connecting surface. It is preferably provided from the side end toward the bottom wall side.

Since the hook portion of the tub having the above configuration is provided so as not to project outward from the end portion on the opposite side of the bottom wall of the second connecting surface, the tub can be used in the same manner as a tub without a hook portion and is easy to use.

(6) In the tub according to (4) or (5), the first connecting surface and the second connecting surface are connected to the bottom wall when the main body portion stands on its own with the connecting portion facing downward. It is preferable that the slope is provided so that the opposite side is arranged below the bottom wall side.

When the tub having the above configuration is self-supporting, the first connection surface and the second connection surface are inclined downward, so that the water adhering to the inner surface of the main body portion passes through the first connection surface, the step portion, and the second connection surface. It easily flows down and has good draining performance.

(7) It is preferable that the tub according to any one of (4) to (6) has a reinforcing portion that is connected to the hook portion and the second connecting surface to reinforce the hook portion.

The tub having the above configuration can suppress deformation or breakage of the hook portion and the connecting portion when, for example, the user holds the hook portion and uses the tub.

(8) In the tub according to any one of (5) to (7), the hook portion has a bent portion that bends toward the bottom wall side, and a through hole is formed in the bent portion. , Are preferred.

When the tub with the above configuration is self-supporting, water does not collect on the hook part, and dirt and mold do not easily collect on the hook part.

Hereinafter, an embodiment of the tub according to the present invention will be described with reference to the drawings.

10 and 11 are views for explaining a usage example of the tub 1. The tub 1 is provided with a hook portion 3 integrally provided with a bottomed cylindrical main body portion 2, and is used in, for example, a bathroom. The tub 1 stores hot water in the main body 2 when washing the body and face, and scoops hot water in the bathtub in the main body 2. The used tub 1 is hung from the bar 12a of the towel rack 12 attached to the wall surface 10 of the bathroom, for example, as shown in FIG. 10, or the floor 14 of the bathroom is in an independent posture as shown in FIG. 11, for example. It is placed in the bathroom and drained. The towel rack 12 is an example of a "bar fixed to the wall surface".

The configuration of the tub 1 will be described. 1 and 2 are external perspective views of the tub 1. The main body 2 of the tub 1 includes a bottom wall 21 and a peripheral wall 23.

FIG. 3 is a front view of the tub 1. The peripheral wall 23 is inclined so as to spread in the outer diameter direction from the bottom wall 21 side (lower side in the figure) to the side opposite to the bottom wall 21 (upper side in the figure).

FIG. 4 is a top view of the tub 1. The bottom wall 21 has a D shape, and the peripheral wall 23 is erected along the outer edge of the bottom wall 21. The peripheral wall 23 includes an arc portion 231 provided in an arc shape and connecting portions 233 connected to both ends of the arc portion 231, and the main body portion 2 is connected to the bottom wall 21 from the opposite side (open end side, upper side). The seen shape (planar shape) forms a D shape.

FIG. 5 is a cross-sectional view taken along the line AA of FIG. The connecting portion 233 includes a first connecting surface 233a, a second connecting surface 233b, and a stepped portion 233c. The first connection surface 233a is located on the bottom wall 21 side (right side in FIG. 5), and the second connection surface 233b is located on the side opposite to the bottom wall 21 (left side in FIG. 5). The step portion 233c is connected to the first connection surface 233a and the second connection surface 233b so that the first connection surface 233a is located inside the second connection surface 233b (center side of the main body portion 2, lower side in FIG. 5). It is provided.

As shown in FIG. 2, the first connection surface 233a and the second connection surface 233b are provided in a plane shape. As shown in FIG. 5, the first connection surface 233a and the second connection surface 233b have their sides opposite to the bottom wall 21 (left side in FIG. 5) outside the bottom wall 21 side (right side in FIG. 5) (FIG. 5). It is tilted so that it is placed on the upper side).

FIG. 6 is a right side view of the tub 1 and FIG. 7 is a left side view of the tub 1. As shown in FIGS. 6 and 7, the hook portion 3 is provided on the outside of the connecting portion 233. The hook portion 3 is a bottom wall from an opening end located on the opposite side (upper side in FIGS. 6 and 7) of the connecting portion 233 to the position of the bottom wall 21 (lower side in FIGS. 6 and 7). It extends in a direction orthogonal to 21 and its tip is bent toward the bottom wall 21 to form a bent portion 34. As a result, the hook portion 3 is integrally provided with the main body portion 2 so as not to project outward from the opening end portion side of the connecting portion 233. The hook portion 3 is provided with a width that allows the main body portion 2 to stably stand on its own when the connecting portion 233 of the tub 1 is on the lower side. The hook portion 3 is connected to and reinforced by the second connecting surface 233b via the reinforcing portion 39. The hook portion 3 has a hook groove 40 having a predetermined width formed between the hook portion 3 and the first connecting surface 233a. That is, the hook groove 40 is formed by the bent portion 34, the reinforcing portion 39, and the first connecting surface 233a.

The hook portion 3 is provided in an L shape or a J shape with the tip portion 33 located on the bottom wall 21 side (right side in FIG. 5) bent toward the bottom wall 21 side. Hook grooves 40 are formed at predetermined intervals W between the hook portion 3 and the first connecting surface 233a. Therefore, in the tub 1, for example, as shown in FIG. 10, the bar 12a of the towel rack 12 can be inserted through the opening of the hook groove 40, and the hook portion 3 can be hooked on the bar. The tub 1 has a reinforcing portion 39 that connects the hook portion 3 and the second connecting surface 233b and reinforces the hook portion 3.

FIG. 8 is a rear view of the tub 1. FIG. 9 is a bottom view of the tub 1. A through hole 35 is provided in the bent portion 34 of the hook portion 3. The through hole 35 is formed along the bent portion 34 so that water flowing along the inner surface of the hook groove 40 flows out of the hook groove 40 through the through hole 35. Further, the hook portion 3 has a recess 37 formed on a support surface 31 located on the opposite side of the connecting portion 233.

Subsequently, how to use the tub 1 will be described. For example, when washing the body or face, the user pumps out the water in the bathtub using the tub 1 or pour the hot water stored in the tub 1 on the body. At this time, since the width of the hook portion 3 is wide, the user can hook the finger on the hook portion 3 and use the tub 1. Since the hook portion 3 is reinforced via the reinforcing portion 39, even if the user hooks a finger on the hook portion 3 and uses the tub 1, the hook portion 3 is not deformed or damaged. Further, since the hook portion 3 is provided so as not to project above the main body portion 2 or outside the opening end portion of the connecting portion 233, the user can use the hook portion 3 if the hook portion 3 does not get in the way when using the tub 1. Instead, the tub 1 can be used in the same way as the conventional tub.

When the bottom wall 21 of the tub 1 is in contact with the floor 14, a gap is formed between the step portion 233c and the floor 14. At this time, the hook portion 3 extending to the position of the bottom wall 21 brings the bent portion 34 into contact with the floor 14 to support the main body portion 2. Since the hook portion 3 is provided in a plate shape having a wide width, the main body portion 2 is supported in a stable posture. Therefore, during the use of the tub 1, the main body 2 does not tilt toward the stepped portion 233c, and the user can use the tub 1 in the same manner as the conventional tub 1.

Since the tub 1 includes the stepped portion 233c, the capacity of the main body portion 2 is smaller than that in the case where the stepped portion 233c is not provided. Therefore, the tub 1 can suppress the amount of water used.

The used tub 1 is hung from the bar 12a of the towel rack 12 and drained, as shown in FIG. 10, for example. That is, the tub 1 is hung from the bar 12a via the hook portion 3 by inserting the bar 12a of the towel rack 12 from the opening of the hook groove 40. The hook groove 40 is provided on the bottom wall 21 side of the center of gravity of the tub 1. Therefore, the tub 1 hooked on the bar 12a rotates toward the bottom wall 21 side (in the K direction in the drawing) with the bar 12a as a fulcrum. Since the bar 12a is located away from the wall surface 10, the tub 1 abuts the portion P opposite to the hook portion 3 of the connecting portions where the bottom wall 21 and the peripheral wall 23 are connected to the wall surface 10 of the bathroom. The bottom wall 21 is hung from the bar 12a in a posture of being slanted downward. As a result, the water adhering to the tub 1 flows down as shown by arrows F1 and F2 in the figure. Therefore, the tub 1 is sufficiently drained and dried, and dirt and mold are less likely to adhere to it.

Further, as shown in FIG. 11, for example, the used tub 1 becomes self-supporting when it is placed on the floor 14 in a posture in which the hook portion 3 and the connecting portion 233 are on the lower side. Since the support surface 31 of the hook portion 3 is provided perpendicular to the bottom wall 21, the tub 1 stands on its own with the bottom wall 21 vertical. Therefore, the water adhering to the tub 1 flows down as shown by arrows F11, F12, and F13 in the drawing, and the surface of the main body 2 (inner and outer surfaces of the bottom wall 21, and inner and outer surfaces of the peripheral wall 23) is dried. Cheap.

At this time, in the connecting portion 233 located on the lower side of the tub 1, the first connecting surface 233a and the second connecting surface 233b are opposite to the bottom wall 21 (right side in FIG. 11) on the bottom wall 21 side (right side in FIG. 11). ) It is tilted to be lower. Therefore, the water that has flowed down from the bottom wall 21 flows down to the floor 14 via the first connecting surface 233a, the stepped portion 233c, and the second connecting surface 233b.

By the way, the hook portion 3 is provided with a bent portion 34 at the tip end portion. Therefore, as shown by the arrow F21 in FIG. 11, when the tub 1 is made to stand on its own, water may flow down and accumulate inside the bent portion 34. However, the hook portion 3 has a through hole 35 formed in the bent portion 34. Therefore, the water that has flowed down to the bent portion 34 flows down to the floor 14 through the through hole 35 and does not collect in the bent portion 34. Therefore, mold and dirt are less likely to collect inside the hook portion 3.

Further, the support surface 31 of the hook portion 3 is provided with a recess 37 in the central portion, and forms a gap between the support surface 31 and the floor 14. That is, the contact area between the support surface 31 and the floor 14 is small. Therefore, even when the tub 1 is drained in a self-standing posture, it is possible to secure air permeability between the support surface 31 and the floor 14 and prevent dirt and mold from adhering to the support surface 31.

As described above, in the tub 1 of the present embodiment, for example, the hook portion 3 is in a posture in which the bottom wall 21 is directed to the wall surface 10 side of the bathroom and the opening of the main body portion 2 is directed to the side opposite to the wall surface 10 of the bathroom. It is hung directly on the towel rack 12 and drained. The main body 2 suspended from the towel rack 12 forms a gap between the bottom wall 21 and the wall surface 10 to ensure air permeability. Therefore, dirt and mold are less likely to occur on the outside of the bottom wall 21. Further, the hot water tub 1 of the present embodiment can be directly hooked to the bar 12a via the hook portion 3 without the S-shaped hook, and is convenient to use. Further, since the hook portion 3 is more compact than the U-shaped handle and does not protrude much from the main body portion 2, it does not easily get in the way when washing the face or the like. Therefore, according to this embodiment, it is possible to realize a hot water tub 1 having good draining performance and usability.

The present invention is not limited to the above embodiment, and various applications are possible. For example, the tub 1 may be used in a place other than the bathroom, such as a washroom. In this case, the tub 1 may be hung on a towel rack in a washroom, for example.

For example, in the tub 1, when the hook portion 3 is hooked on the bar 12a, the portion of the peripheral wall 23 at a position facing the portion where the hook portion 3 is provided has the opening end side closer to the closed end side. The hook portion 3 may not be provided so as to be arranged below. However, by adopting such a configuration, when the tub 1 is suspended from the bar 12a via the hook portion 3, the water adhering to the main body portion 2 naturally flows down, and the draining performance is good.

For example, as in the tub 1A shown in the first modification of FIG. 12, the peripheral wall 23A may be provided in a cylindrical shape along the circular bottom wall 21A to form the main body portion 2A (FIGS. 12A and 12B). )). That is, the tub 1A does not have to be self-supporting because the peripheral wall 23A is not provided with a connecting portion. However, by being self-supporting like the tub 1 of the above-described form, for example, even if the towel rack 12 is not provided or the towel rack 12 is not used, the tub 1 can be self-supporting and drained, and the draining performance is good.

Like the tub 1A shown in FIG. 12, the peripheral wall 23A may not include the first connecting surface 233a, the second connecting surface 233b, and the stepped portion 233c, and the hook groove 40 may be formed only by the hook portion 3A (FIG. 12). (C)). However, as in the above embodiment, by forming the hook groove 40 between the second connecting surface 233b and the hook portion 3, the hook portion 3 is integrated with the main body portion 2 so as not to project too much outward from the peripheral wall 23. The hook portion 3 does not get in the way when used.

Further, the hook portion 3A may be provided obliquely from the open end portion of the peripheral wall 23A toward the outer diameter of the main body portion 2A (FIG. 12A). However, as in the above embodiment, the hook portion 3 does not get in the way because the hook portion 3 does not project outward from the open end portion of the peripheral wall 23.

For example, as in the tub 1B shown in the second modification of FIG. 13, the hook portion 3B is on the bottom wall side of the second connection surface 233b with respect to the D-shaped main body portion 2 (peripheral wall 23) (FIG. 13 (a)). It may be provided in an arch shape from the end portion toward the bottom wall 21 side (FIGS. 13 (b) and 13 (c)). The hook portion 3B has a hook groove 40 formed between the hook portion 3B and the first connection surface 233a. The hook portion 3B may be coupled to the second connecting surface 233b via the reinforcing portion 39 to reinforce the hook portion 3B. Also in this case, it is desirable that the hook portion 3B is provided so as not to project outward from the open end portion (upper end portion in the drawing) of the connecting portion 233.

For example, as in the tub 1C shown in the third modification of FIG. 14, the hook portion 3C is on the bottom wall 21 side of the second connection surface 233b with respect to the D-shaped main body portion 2 (peripheral wall 23) (FIG. 14 (a)). It is not necessary to provide the reinforcing portion 39 because it is integrally provided from the end portion toward the bottom wall 21 side (FIGS. 14 (b) and (c)). The reinforcing portion 39 may be provided by stealing meat.

For example, as in the tub 1D shown in the fourth modification of FIG. 15, the hook portion 3D is extended from the opening end portion of the connecting portion 233 toward the bottom wall 21 side to the outside of the connecting portion 233 of the peripheral wall 23, and the hook is hooked. Meat theft may be provided on both sides of the portion 3D (FIGS. 15 (a) and 15 (b)).

For example, in the tubs 1A to 1D of the first to fourth modified examples, the open end portion of the main body portion 2 is folded outward and an edge portion Eg is provided. The user uses not only the hook portions 3A to 3D but also the tubs 1A to 1D by hooking a finger on the edge portion Eg. The edge portion Eg may be omitted. Further, the edge portion Eg may be provided in the tub 1 of the above-described form.

For example, the connecting portion 233 may not include the stepped portion 233c between the first connecting surface 233a and the second connecting surface 233b. However, by providing the stepped portion 233c, the hook portion 3 can be provided on the outside of the connecting portion 233 so as not to project outward from the end portion located on the opposite side of the bottom wall 21 of the connecting portion 233, and the tub can be provided. The hook portion 3 does not get in the way when using 1. In addition, the tub 1 is easy for the user to use and has a good appearance.

For example, the first connecting surface 233a and the second connecting surface 233b do not have to be inclined so that the side opposite to the bottom wall 21 is arranged below the bottom wall 21 side when the tub 1 is made to stand on its own. However, by providing the inclination applied to the first connection surface 233a and the second connection surface 233b, when the tub 1 is made to stand on its own, the water adhering to the inner surface of the main body 2 becomes the first connection surface 233a, the step portion 233c, and the step portion 233c. It easily flows down through the second connecting surface 233b and has good draining performance.

For example, the reinforcing portion 39 may not be provided. However, as in the above embodiment, when the hook portion 3 is connected to the second connecting surface 233b via the reinforcing portion 39 and is reinforced, for example, when the user holds the hook portion 3 and uses the tub 1. Deformation and breakage of the hook portion 3 and the connecting portion 233 can be suppressed.

For example, the through hole 35 may not be provided. However, by providing the through hole 35 in the bent portion 34 of the hook portion 3 as in the above embodiment, water does not collect inside the hook portion 3, and dirt and mold are less likely to accumulate in the hook portion 3.

For example, the recess 37 may not be provided. Further, the through hole 35 may be a plurality of round holes instead of a long hole.
