Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a jet bath device in which the direction of the jet flow and its strength can be adjusted.

(Prior art) A conventional jet bath device in which jet outlets are provided on the back and foot sides of a bathtub and jets are supplied simultaneously or alternatively from the back and foot sides is disclosed in Japanese Utility Model Publication No. 60-7057. This is a well-known method as shown in .

(Problem to be solved by the invention) In such a conventional example, a valve device is interposed in each piping leading to each jet outlet, and since the jet flow direction is switched by opening and closing each valve device, a plurality of valves are required. This requires equipment and is disadvantageous in terms of cost. In order to solve this problem, a closed type switching valve A shown in Fig. 4 is installed in the piping branch leading to each jet outlet, and this switching valve A is installed on the bathroom wall as shown in Fig. 3 of the bathtub. The control may be performed using selection switches B1 and B2, which are provided facing each other on the left and right, corresponding to each jet outlet of the operating device B, which is installed parallel to the dorsal foot direction. That is, when the selection switch B1 is turned on, the closure A1 is rotated clockwise to increase the jet force from one jet outlet, and when the selection switch B1 is continued to be turned on, the closure A1 continues to rotate and the other one is increased. The jet force from the jet outlet is reduced. When one selection switch B2 is turned on, the effect opposite to the above occurs, and the jet force from the other jet outlet increases, and when it is continued to be turned on, the jet force from one jet outlet decreases. However, with this configuration, as shown in FIG. 5, the selection switches B1 and B are
2 and the jet outlet are reversed, and the installation position of the operating device is therefore restricted, resulting in a problem that construction is difficult.

(Means for Solving the Problems) The present invention aims to solve these problems, and for this purpose, the present invention has jet outlets provided on the opposite surfaces of the back and foot sides of the bathtub. the outlet, a switching valve for switching the direction of the jet interposed in the piping branch leading to both jet outlets, and a switch valve installed on the bathroom wall in parallel with the back and foot direction of the bathtub to the left and right corresponding to the opposing jet outlets. It consists of an operating device having a selection switch for jet flow switching provided opposite to each other, and a polarity conversion means is provided at the connection between the drive motor of the switching valve and the controller that controls the drive motor.

(Function) If the positional relationship between the selection switch of the operating device and the jet outlet of the bathtub is reversed depending on the construction site, the above relationship can be corrected by changing the polarity of the control signal to the drive motor using the polarity conversion means. It has been corrected and is now official.

(Embodiment) FIG. 1 is an overall configuration diagram showing an embodiment of the present invention. Reference numeral 1 denotes a bathtub, and jet outlets 2 and 3 are provided on both opposing dorsal and leg sides. Reference numeral 4 denotes a pump for sucking hot water from the bathtub 1, and a switching valve A shown in FIG. 4 is interposed at a branch portion of a pipe 5 downstream of the pump 4 and leading to each of the jet discharge ports 2 and 3. Further, a solenoid valve 6 and a filter 7 are provided in parallel with the pump 4 to change the pump capacity between large and small levels. 8 is a drive motor that rotates the closing element A1 of the switching valve A. In FIG. 2, the drive motor 8 is connected to a controller 9, and is installed on the left and right sides of the operating device B, which is installed parallel to the back and foot direction of the bathtub 1 on the bathroom wall, in correspondence with the opposing jet outlets. When the selection switches B1 and B2 are turned on, output voltage is generated at the positive output terminal 9a and negative output terminal 9b of the controller 9, and the positive output rotates the drive motor 8 in the normal direction, and the negative output rotates it in reverse. By controlling the switching valve A, it is possible to adjust the strength of each jet flow. Further, a polarity conversion means 10 is provided at the connection between the controller 9 and the drive motor 8, and in this embodiment, a connector 10a with reversed polarity is connected in parallel with a regular connector 10b. Connector 10c on the side to connector 1
The polarity can be changed by changing the connection from connector 0b to connector 10a.

In the above configuration, when the pump 4 is driven, hot water in the bathtub 1 is sucked and sent to the jet outlet ports 2 and 3 through the piping 5, so that a jet bath or a bubble bath can be performed in the bathtub 1. Next, if you want to increase the jet force from the jet outlet 2, turn on the selection switch B1 of the operating device B. An output voltage will be generated at the positive output terminal 9a of the controller 9, and the drive motor 8 will move in the clockwise direction as shown in FIG. Closing child A1
is rotated in the normal direction to increase the opening degree of the outlet A2 leading to the jet outlet 2 of the switching valve A, thereby increasing the jet force from the jet outlet 2. At this time, the forward rotation of the drive motor 8 continues as long as the selection switch B1 is turned on.
The closing member A1 stops at the position where it comes into contact with the stopper A4, and when the other selection switch B2 is turned on, the operation opposite to the above is performed, and by turning on the switch B2, the jet force from the jet jet outlet 3 is strengthened. , the jet force from the jet outlet 2 is weakened by continuous injection.

Therefore, when the operating device B is installed at the D position in Fig. 5, the selection switches B1 and B2 are
Although the positional relationship between the jet outlet ports 2 and 3 is reversed,
In that case, connector 10c and connector 10
If A is connected, the direction of rotation of the closure A1 will be reversed from the conventional one, and the operability will be the same as when it is installed in the normal position.

Although the switching valve in this embodiment is designed to switch only the strength of the jet force from each jet outlet,
It may be one that blocks the jet flow from one of the jet discharge ports.

(Effects of the invention) As described above, according to the invention, in a jet bath device that is provided with a plurality of jet discharge ports and is capable of adjusting the jet flow from each jet discharge port, there is no need to use a plurality of valve devices as in the past. Since there are no restrictions, it is possible to provide a jet bath device that is inexpensive and has a high practical effect because it is not restricted by the installation conditions of the operating device.
