Description

[Detailed description of the invention] (a) Industrial application field The present invention is mainly used in a bathtub equipped with a recirculation type bathtub having a discharge port and a water supply port provided above and below,
This invention relates to a circulation device for a bathtub that adjusts the flow of hot water to a flow suitable for warming the body and that can be easily installed in any bathtub of the same type.

(b) Conventional technology In the case of conventional circulation bathtubs, Figures 12 and 1
As shown in Figure 3, water sucked from the water supply port a passes through the heating pipe c of the bath pot b and gradually reaches the discharge port d.
The hot water is discharged as hot water, but inside the bathtub e, it is diffused along the surface of the hot water, as seen in both figures.

Therefore, a person taking a bath usually receives hot water from the upper front, and has to stir the water with his/her hands while taking a bath.

(c) Problems to be solved by the invention As mentioned above, the hot water discharged from the outlet d is diffused along the upper surface of the bathtub, which requires stirring by hand and is harmful to the human body. Experimental results have shown that it is important to heat the back and waist regions, and that it is preferable to heat these regions at the same time as the front of the human body, or even more so.

However, as mentioned above, in the conventional method, hot water flows from the front, so the conventional method could not be said to be suitable.

(d) Means for solving the problem Therefore, in the present invention, while changing the flow of hot water as described above in the bathtub to improve the flow to the back and waist of the bather, It is an object of the present invention to provide a circulation device that can be attached extremely easily to any type of bathtub without requiring any work.

That is, a cross-sectional flow divider frame with openings at both ends is formed into a floating structure (for example, when using materials with heavy specific gravity such as wood or synthetic resin, an air chamber is provided inside), and the frame is always kept in contact with the water surface. While the vertical wall stands upright in the water and the horizontal wall floats on the water surface, a guide string with weights attached to both ends is attached to one side of the flow divider frame so that the flow divider frame is always in a position opposite to the discharge port. One weight is placed outside the bathtub, and the other weight is suspended inside the bathtub.This allows hot water from the outlet to circulate along the inner wall of the bathtub. This system is designed to sufficiently heat the area around the back of the bather without stirring the bath by hand.

Furthermore, control plates for regulating the flow rate and direction of hot water are pivotably supported at the openings at both ends so that the flow rate and direction of the hot water can be adjusted as necessary to suit the preferences of the bather. It is designed to have a curved shape to smooth the flow of hot water.

The gist of the present invention will be explained below based on embodiments shown in the drawings.

(E) Embodiment FIG. 1 is a perspective view showing an embodiment of the device of the present invention;
FIG. 2 is an exploded perspective view of the device, FIG. 3 is a plan view of the bathtub showing how the device is used, and FIG. 4 is a partially cutaway side view of the bathtub.

In the drawing, reference numeral 1 denotes a flow diversion frame, which is composed of a vertical wall 2 and a horizontal wall 3, has openings 4 at both left and right ends, and has a diversion fin 5 protruding from the center of the vertical wall 2. Diagonal projecting edges 2a are provided at both ends of the vertical wall 2, control plates 6 are provided in each opening 4, and the bolts 7 fixed to the control plates 6 are inserted into the through holes 3a of the horizontal wall 3 and tightened. The control plate 6 is rotated about a bolt 7, and its rotational position is fixed by a nut 8.

Further, the free end 6a of the control plate 6 is bent to face the protruding edge 2a, and regulates the flow rate and direction of hot water as described later. Reference numeral 9 denotes a guide string, which is made of a bead chain, has heavy hangings 10 and 11 connected to both ends, passes through the guide hole 12 of the horizontal wall 3, and performs a slight locking action between it and the guide hole 12. It's like this.

(F) Effect The device of the present invention having the above-described configuration is installed in the flow dividing frame with the weight 10 placed on the short wall 20a of the bathtub 20 and the other weight 11 hanging down, as shown in FIGS. 3 and 4. 1 facing the discharge port 22, the hot water is discharged from the openings 4, 4 in a branched manner to both the left and right sides as shown by the cross marks, flows along both long walls 20b of the bathtub 20, and hits the opposite short wall 20a. It also circulates downward, warming the back and waist of the body.

Further, as shown in the third diagram, the flow of hot water forms opposing spirals rotating in opposite directions to promote temperature rise and uniformity. Further, by adjusting the opening degree of the opening 4 by adjusting the control plate 6, the flow rate and direction of the hot water can be regulated according to the shape of the bathtub and the bather's preferences, allowing for a comfortable and warm bath.

5 and 6 show the case where the bath pot 21 is located at the corner of the bathtub 20, and one side of the control plate 6 is slightly opened to rotate hot water evenly.
In the case of FIG. 7 and FIG. 8, the bath pot 21 is located on the side of the long wall 20b, and in this case, the degree of opening of the control plates 6, 6 is adjusted according to the bathing position of the bather, as shown by the x mark. It adjusts the flow.

Furthermore, in the case of FIG. 9 and FIG. 10, one control plate 6 is closed and the other is opened, and in this case, a large flow of hot water is generated along the inner circumference of the bathtub. It is.

The above has described the relative position between the bathtub and the bathtub, but even if the surrounding wall of the bathtub is sloping, the device of the present invention can be easily suspended, and the operation in that case is the same as described above. be.

Furthermore, whether the corner of the bathtub is square or curved, the action and effect are essentially the same;
Needless to say, in the case of a curved shape, there is less frictional resistance, the circulation is smoother, and the effect is greater.

The above is a case of a circulating bathtub, but in the case of a hot water supply type where water is boiled outside the bathtub and injected into the bathtub via a hot water supply pipe, hot water is dropped from above into the bathtub from a faucet. However, the first
As shown in Figure 1, a mesh opening 30 or a surrounding frame 31 is provided to weaken the falling flow velocity and allow the flow to flow into the flow dividing frame 1'.
It can be used in the same manner as in the previous embodiment if it is discharged from the openings 4', 4', and if necessary, by configuring a cross-sectional mold as a mold to reduce the falling flow velocity. Of course, in this case, there is no need to change the type as long as the flow rate is adjusted by adjusting the flow rate at the faucet.

(G) Effects of the Invention As described above, according to the circulation device of the present invention, regardless of the size of the bathtub, the shape of the corners, and the inclination of the surrounding wall, the length L is at least 25 to 60 cm, and the width W is 5 to 20 cm.
By regulating the height (cm) and height (h) to approximately 5 to 15 cm, proper circulation will occur, so the water will boil quickly, and the water will circulate to the back and waist of the bather, resulting in a rapid body warming effect. In particular, since the flow rate and outflow direction at the opening can be freely selected using the control board, the flow rate can be adjusted appropriately to the affected area of the body, etc., while this device can be used regardless of the shape of the bathtub or the position of the outlet. It can be used directly in any bathtub without requiring any modification, can be removed freely, and is convenient for cleaning the bathtub, and therefore has significant advantages over conventional bathtubs. When used in bathtubs at home, it can have excellent effects such as improving health and saving fuel.
