Description

  The present invention relates to a bathtub, and more particularly to a bathtub structure that allows a bather to take a whole body bath with a small amount of hot water.

  As shown in FIG. 7, the conventional bathtub 100 includes a bottom portion 110 having a step 105 and a side wall portion 120 rising from the periphery of the bottom portion 110. When bathing in the bathtub 100, as shown in FIG. 8, in addition to the posture where the bather is sitting on the bottom 110 as shown in FIG. You can sit down at 105 and enjoy a half-bath bathing in hot water to the abdomen, for example, to the depths of the abdomen.

The above-described conventional bathtub 100 is designed to have a depth that allows the bather to bathe in the hot water to the position of the shoulder of the bather in the sitting posture in the case of a whole body bath.
However, in the case of a normal whole body bath, since a large amount of hot water is required, water and utility costs are increased. In particular, recently, awareness of running costs such as water bills and gas bills and energy consumption has increased, so bathers may bathe with a small amount of hot water. In order to perform a whole body bath with a small amount of hot water, the user must take a low posture in the bathtub 100, that is, a sleeping hot water posture, as shown in FIG. It is designed on the premise of taking a bath in a raised posture, and it is not assumed that the whole body bath will be performed in the posture of a sitting posture with a small amount of hot water. For this reason, as shown in FIG. 10, the bather has to put his body on his back with his head resting on the backrest 130 of the bathtub, and in that case, he has to take a cramped posture with his chin pulled. I couldn't enjoy a comfortable full body bath because of the strain on the neck.

  In view of the problems described above, an object of the present invention is to provide a bathtub that can comfortably and comfortably take a whole body bath with a small amount of hot water.

In order to achieve the above object, the bathtub of the present invention includes a backrest portion for supporting the bather's back in a sitting posture on the inner wall surface, and the backrest portion is continuously provided from the bottom portion to the upper edge and outwards. Two first recesses are provided at positions that are inclined and spaced apart from each other in the height direction intermediate part of the backrest part, and the first recesses are recessed outwardly from the backrest part of the periphery to the backrest part in the entire periphery. enclosed, bather it is characterized by that can take supine Neyu posture in bath put the back of the head in the first recess.
The bathtub according to the present invention preferably includes a second recess for supporting a bather's neck at the upper edge of the inner wall, and the second recess and the first recess are respectively provided at positions spaced above and below the inner wall. Yes.
In the bathtub of the present invention, the first concave portion and the second concave portion are provided at positions spaced apart from each other above and below the inner wall surface, and a bather is supported by the second concave portion in a posture of sitting in the bathtub. The thing which can take is good .
The bathtub of this invention may be provided with the 3rd recessed part which mounts a bather's back head in the position lower than said 1st recessed part of the other inner wall surface facing the said inner wall surface .
As for the bathtub of this invention, the step is formed in one edge part of a bottom part, and the backrest part provided with the 1st recessed part may be formed in the inner wall surface facing a step.

  According to the present invention, the bather accumulates hot water to a height of, for example, about 200 to 250 mm, shallower than the first concave portion, so that half-body bathing is possible in the sitting posture, and the back of the head is made into the first concave portion in the bathtub. The whole body bath can be performed by putting it on the back and sleeping on the back. At this time, since the occipital region is stably held in the first recess, the posterior posture from the occipital region to the back region can maintain a substantially straight natural line without bending the cervical region unnaturally. The whole body bath can be performed with a comfortable sleeping bath posture. Moreover, according to the bathtub of the present invention, the whole body bath can be performed with a small amount of hot water, thereby reducing running costs and contributing to energy saving.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 1 is a perspective view showing a bathtub 1 according to an embodiment of the present invention. 2 is a cross-sectional view taken along line AA in FIG.
This bathtub 1 is comprised from the main-body part 10 formed in the box shape for a central part to store hot water, and the peripheral part 20 extended from the upper edge of this main-body part 10 to the horizontal direction outer side. The main body 10 includes a bottom 11 and a side wall 12 rising outward from the periphery of the bottom 11. A step 15 that can be used for sitting or the like is formed at one end of the bottom portion 11, and a backrest portion 18 that is inclined outward from the bottom portion 11 is formed on the inner wall surface 17 of the side wall portion facing the step 15. Has been.

Although the above structure is the same as that of the conventional bathtub, the bathtub 1 according to the embodiment of the present invention is characterized in that a bather can perform whole body bathing in addition to half-body bathing with a small amount of hot water.

The first recess 30 is formed, for example, as a hemispherical curved concave surface so that the back of the bather can be stably placed.
The first concave portion 30 is formed in the middle of the width direction of the backrest portion 18 and the direction of the arrow X in the figure, but depending on the size of the bathtub 1, the first concave portion 30 may be provided close to either the left or right side. good.
The height H from the bottom where the first recess 30 is provided is preferably set to 250 to 300 mm so as to conform to the general human body shape, and the width W (see FIG. 1) of the first recess is about 120 to 150 mm. The depth D (see FIG. 2) is designed to be about 20 to 50 mm.

  According to the bathtub 1 configured as described above, the bather accumulates hot water until the amount of hot water is such that the whole body bath can be performed in the sleeping bath posture, and, for example, the height h is lower by about 50 to 100 mm than the first recess 30. Hot water is accumulated until it becomes, and the whole body bath can be performed by placing the back of the head in the first recess 30 in the bathtub 1 as shown in FIG.

  Therefore, according to the bathtub 1 of this embodiment, a whole body bath can be performed with about 50% of hot water. This can reduce running costs and contribute to energy saving.

Drawing 3 is a perspective view showing bathtub 1A concerning the 1st modification of an embodiment of the present invention. In this bathtub 1A, a second recess 31 is formed on the upper edge of the inner wall surface 17 provided with the first recess 30 to support the neck of the bather.
According to this bathtub 1A, in addition to obtaining the same effect as that of the above embodiment, the bather takes a posture of the sitting posture with the back supported by the backrest portion 18 with a small amount of hot water, so that the back of the head It is possible to perform half-body bathing while holding comfortably. At this time, the bather can take a comfortable posture while performing half-body bathing as shown in FIG. 4 by tilting the head slightly backward and supporting the neck portion in the second recess 31.
