Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub having a massage function by a jet from a jet nozzle.

[0002]

2. Description of the Related Art A jet nozzle is disposed below or above the water surface of a bathtub, and jets jetting toward the inside of the bathtub are provided on shoulders, backs,
There is one that is applied to the waist, legs, etc. to obtain a massage effect (see Japanese Utility Model Publication No. 4-70024).

[0003]

In this type of conventional bathtub, a jet nozzle is arranged below or at an appropriate position on the water surface so as to apply the jet to the shoulders, back, waist, legs and the like of the bather. However, in the shoulder jet, the position of the jet nozzle is limited near the upper edge of the bath due to the relationship between the bather and the shape of the bathtub, and even if an attempt is made to make a shoulder jet in the usual bathtub shape, the nozzle position is near the upper edge of the bathtub. Because it is on or near the surface of the water,
Even if water splashes or a jet is applied to the shoulder, it cannot be expected to be effective in eliminating shoulder stiffness because it hits the acupoint of the shoulder at an oblique angle.

Further, in the conventional example, since the jet nozzles are individually arranged at the positions facing each part of the bather in order to achieve the jet massage effect on the waist and legs, the bathtub which is expensive in price It was.

According to the present invention, the relationship between the shape of the bathtub and the position of the jet nozzle is devised so that the effective jet of the shoulders, the back, the waist, the legs and the like can be comfortably hit by a small number of jet nozzles. The purpose of this massage is to provide an expensive bathtub.

[0006]

In order to achieve the above-mentioned object, the present invention, in the invention of claim 1, forms a step for sitting on one side of the bathtub, and above this step and on the one side wall. And a pair of jet nozzles on the other side wall of the bathtub.

Therefore, with this pair of jet nozzles,
When the bather sits on the step, the waist is massaged with a jet stream, and when the foot is placed on the step, the foot jets can be massaged, and the hips are placed on the bottom of the bathtub and the back is placed on the tip of the step. Then, by applying a jet at a right angle to the mouth of the shoulder, effective massage can be performed by the jet of the shoulder.

In addition, in the invention of claim 2, in the structure of claim 1, a pillow is formed on the upper edge of one side wall of the bathtub. Therefore, by placing the head of the bather on this pillow, the jets from the pair of jet nozzles accurately hit the shoulders of the bather, and the shoulder massage by the jets can be performed reliably and easily.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be specifically described below with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a sectional view of the same, FIGS. 3 to 5 show usage modes, FIG. 3 is a shoulder massage use state, and FIG. 4 is a waist massage use. The state, FIG. 5 is a cross-sectional view showing the usage state of the back and foot massage.

A bathtub 1 has a step 2 for sitting on one side. A pillow 3 is formed on the upper edge of the bathtub 1 on the step 2 side so that the user can take a bath with the head resting on the pillow while lying in the bathtub 1. Reference numeral 4 is a jet nozzle, which is arranged below the pillow 3 on the side wall 5 of the bathtub above the step 2 at a shoulder width interval (two pairs). Reference numeral 6 is a back jet nozzle arranged on the other side wall, and a pair (two pieces) is provided at a predetermined position corresponding to the back of the opposite wall surface 7 facing the jet nozzle 4 of the bathtub 1.
It is arranged.

Reference numeral 8 denotes a handgrip provided on both longitudinal side walls of the bathtub 1, which has a bilaterally symmetrical shape so that the bathtub can be used in any direction. Reference numeral 9 denotes a drain plug provided on the bottom surface of the bath tub 1, which is arranged at a central position where it does not interfere with which direction the bather is facing.

As shown in FIG. 2, the size of the bathtub 1 and the size of the jet nozzles 4 and 6 in relation to the size of the bathtub 1 are 1200 or 1400 mm.
The height is 640mm, and the height of step 3 is 200 from the bottom.
mm, the depth is 200 mm, the jet nozzle 4 is provided 200 mm below the pillow 3 of the bathtub 1, and the jet nozzle 6 is provided 350 mm above the bottom surface. According to this dimension, bathing of the shoulder, waist, back, and feet is possible. The jet can be effectively applied to each part of the person.

It should be noted that the depth dimension of the above step 2 is such that when the bather puts his / her head on the pillow 3 and the back is in contact with the tip of step 2, the angle Θ of the back is not within 30 degrees. Since it becomes unstable, it is necessary to limit it within 250 mm at the maximum, and in order to sit stably, 200
The optimum value is about mm.

Further, by forming the pillow 3, the bather naturally places the head on the pillow 3 and naturally the jet nozzle 4
It is possible to easily and surely massage the shoulder by facing the shoulder of the bather, but the pillow 3 is not always necessary to perform the shoulder massage. For example, the upper edge of the side wall of the bathtub 1 is entirely raised. The bathtub may be a bathtub in which the head is placed at an arbitrary position on the rising portion, or the rising portion itself may be omitted.

[0015]

According to the present invention, a step for sitting is formed inside one side of the bathtub, and a pair of jet nozzles are provided above the step and on one side wall and a pair of jet nozzles are provided on the other side wall of the bath. Since the jet nozzle is provided, the bather can massage each part of the body such as the shoulder, leg, and waist by the jet from the jet nozzle above the step. Further, when the shoulder massage is performed, the bather places the back on the tip of the step and lays the bed, and in that posture, the jet impinges on the shoulder mouth at an angle close to a right angle, which enables effective massage. If the pillow is formed on the upper edge of the bathtub side wall on the step side, the shoulder massage can be performed accurately and easily.
