Abstract

PURPOSE:To enhance the massage effect by applying alternately stimulation by each different strength to the right and the left of the waist part by exhausting an exhaust water flow from plural adjacent jet nozzles by switching it at a prescribed interval by a motor-driven changeover valve. CONSTITUTION:When a circulating pump 4 is driven after putting water into a bathtub 1, bathtub water goes into a water circuit from a circulating port 3, pressurized by the circulating pump 4, separated into water circuits 6a, 6b, and thereafter, only one of them further passes through a changeover valve 8 and reaches a water circuit 6c and exhausted from a jet nozzle 2. The bathtub water which goes into the jet nozzle 2 is exhausted to a negative pressure chamber 2h from a water flow exhaust port 2g, a negative pressure area is generated in the outside periphery of jet water and air is sucked through an air suction tube 7, and a jet bubble flow is generated as a bubble exhaust flow in the bathtub 1. When a rotor 8b of a changeover valve 8 is rotated alternately by 90 degrees to the right and the left at an interval of 1-10 seconds by a controller 9, two pieces of jet nozzles execute each reverse operation, and repeat to exhaust and stop a jet flow.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bathtub water system in which domestic bathtub water is circulated and impinges on the body of a bathing person as a jet stream from a jet nozzle to obtain a pine surge effect. This relates to a circulation device.

2. Prior Art A conventional bathtub water circulation system is known, for example
57, Japanese Patent Laid-Open No. 58-103456, and the like. That is,
Figure 4(a) and (b) and Figure 5(a) and (b)
) will be explained below.

In FIG. 4, 21 is a bathtub, 22-25 are jet nozzles, 26 is a circulation pump, 27 is a switching device, 28 and 29 are air suction pipes, 30-32 are water circuits, 33 and 3
4 is a solenoid valve, the opening and closing of which is controlled by a switch 35. In this device, a circulation pump 26 is operated to suck bath water from a suction port 36 into a water circuit 30. * Circulate through the ring pump 26, water circuit 31, 32 and jet nozzles 22-25. Then, by controlling the magnetic valves 33 and 34 in a timely manner, the jet nozzles 22 and 23
, or 24 and 25. The jet streams from each of the two jet nozzles are the same, but the opening and closing of electromagnetic valves 33 and 34 are controlled to control the presence or absence of jet streams from each of the two jet nozzles.

In addition, in FIG. 5, 41 is a bathtub, 42 to 45 are jet nozzles, 46, 47, 48a to 48c are water circuits,
49 is a circulation pump, 50 is a bypass path of the circulation pump 49, vI~ν4 1 represents a magnetic valve, and the opening degree of the solenoid valve v4 provided in the bypass path 50 is controlled to operate the jet nozzles 42~
Increase or decrease the amount of circulating water sent to jet nozzle 42~
It gives strength and weakness to the jet stream of 45. In addition, the presence or absence of water passing through each jet nozzle is controlled by opening and closing the solenoid valves v1 to V, and in combination with the 11-section control of the opening degree of the solenoid valve v4, the jet flow from each jet nozzle is controlled by the strength and weakness, etc. The ejection time can be freely controlled.

Problems to be Solved by the Invention However, in the above configuration, two solenoid valves are used in the example shown in FIG. Although it is a good method with a low investment cost, it is said that the changes in the jet flow that affect the human body are somewhat monotonous. There was one question. In addition, in the example shown in Figure 5, a magnetic valve 1 is provided corresponding to each jet nozzle, so it is possible to control each jet individually. The problem was that it was monotonous.

The present invention is different from the above-mentioned conventional method! This solution solves one problem. One electric switching valve is installed in the branch water circuit to multiple jet nozzles that are close to each other, and the circulating water is controlled to flow through the multiple jet nozzles at predetermined intervals. The purpose of the switching valve is to enable individual control of multiple nozzles and increase the added value of household jet nozzles with low investment costs.

Means for Solving the Problems The present invention, which is distantly related to the above objects, includes a bathtub, a plurality of jet nozzles provided close to each other on a side wall of the bathtub, and for spouting bath water, and a plurality of jet nozzles provided on the side wall of the bathtub, A circulation port for sucking bath water, and a connection between the jet nozzle and the circulation port;
a water circuit for guiding the circulation of bath water; and a water circuit provided in the water lock;
A circulation pump that circulates the bathtub water, an electric switching valve that is installed at a branch of the water circuit to the jet nozzle and switches the flow of bathtub water to each jet nozzle, and switching of the electric switching valve is performed at predetermined intervals. It is equipped with a controller.

Effect With the above configuration, bath water from each jet nozzle is spouted by the controller by switching the muscle fatigue electric switching valve at predetermined intervals, so that, for example, a strong jet stream is intermittently jetted on the left and right sides of the lower back in short periods of time, alternating between the left and right sides. Therefore, it provides stronger stimulation than constant jetting, provides a more effective pine surge effect to the lower back area, and eliminates muscle fatigue quickly and effectively.

Example Examples thereof will be described below with reference to the drawings.

FIGS. 1 and 2 show the embodiment, l is a bathtub, 2
are fixed to the upper portions of the left and right side walls 1a of the bathtub 1 with jet nozzles that eject bathwater and bathwater containing bubbles.

3 is a circulation port provided at the lower part of the side wall 1a of the bathtub 1, 4 is a circulation pump, 5.6 and 68 to 6d are water connections between the jet nozzle 2 and the circulation port 3, and a circulation pump 4 is provided in the middle. circuit, 7 is an air suction pipe that guides the air sucked in by the ejector effect of the jet nozzle, 8 is a switching valve for selectively using the two jet nozzles 2 on the right side, and water circuit 6a.
and the two water circuits 6c.

Further, the jet nozzle 2 has connection ports 2c and 2d with the water circuit, a shutoff valve 2f of the jet nozzle 2 at the end of the water circuit, a connection port 2e with the air suction pipes 7a and 7b, and a bathtub 1, as shown in the second part. The flange 2 to be attached to the perforation 1b of the side wall 1a has a water jet outlet 2g, a gasket 2, a fixing flag 2b, a screw fitting part 2n for fixing, a negative pressure chamber 2h for bubble suction, and a connection port with the water circuit. 2c and 2d, a stopper 2r for the connection port 2d, a connection port 28 with the air suction pipe, and the like. The jet nozzle 2 is connected to the side wall 1a of the bathtub l.
The flange 21 of the jet nozzle 2 is applied to the perforation 1b provided in the hole 1b, and the fixing flag 2b is fixed by screw fitting at the screw fitting part 2n via the packing 2m. Furthermore, the jet nozzle 2 has its connection port 2c and water circuits 6c and 6d.
is connected to.

Further, the circulation port 3 is fixed to the side wall 1a of the bathtub 1, and the water circuit 5
After connecting to the circulation pump 4 at the water circuits 6.6a and 6b
Connect with. On the other hand, the connection ports 2e of the left and right jet nozzles 2 are connected to an air suction pipe 7, and are open to the atmosphere above the upper end 1b of the bathtub 1. The switching valve 8 and the circulation pump 4 are electrically connected to the controller 9. Also,
The switching valve 8 includes a rotor 8b rotated by a motor drive unit (not shown) whose rotation is controlled by a controller 9;
It consists of a case 8a that houses this. Rotor 8
The water holes 8N and 81m of b are the water holes 8 of case 8a.
p, 8Q.

and 8r, etc., if any two match, water can be passed. In addition, corresponding to these water passage ports 8p to 8r, connection ports 8c, 8d, and 8e with the water circuit are connected to the water circuits 68 and 6c, respectively. Of course, the rotor 8b and case 8a are tightly coupled.

With the above configuration, when the circulation pump 4 is driven after filling the bathtub l with water, the bathtub water enters the water circuit from the circulation port 3, is pressurized by the circulation pump 4, and is divided into the water circuits 6a and 6b, and then further to one side. The water reaches the water circuit 6c through the switching valve 8 and is ejected from the jet nozzle 2.

That is, the bathtub water that has entered the jet nozzle 2 is ejected from the water jet outlet 2g into the negative pressure chamber 2h, generates a negative pressure area around the outer circumference of the jet water, sucks air through the air suction pipe 7, and As shown in the figure, the bubbles are mixed into the jet water, and a jet bubble flow is generated in the bathtub 1 as a bubble jet flow shown in FIG. 1a. As shown in FIG. 1, the bubble flow into the bathtub 1 simply becomes a continuous jet flow A in the jet nozzle 2 on the left side where the switching valve 8 is not provided. However, in the jet nozzle 2 on the right side provided with the switching valve 8, a different jet flow is obtained. That is, in FIG. 3, when the water inlets 81 and 8■ of the rotor 8b are in the positions shown in the figure, water is ejected from the jet nozzle 2 (upper side in FIG. 1a) connected to the water circuit 6c, and at this time, water is emitted from the opposite side. At the jet nozzle 2 (lower side of Fig. 1a), the jet flow is stopped. When the rotor 8b rotates 90 degrees clockwise under the control of the controller 9,
Water port 8I of rotor 8b! , and 811 are connected to water ports 8p and 8r of case 8a, respectively. As for the circulating water, bath water containing air bubbles is ejected from the jet nozzle 2 on the lower side of FIG. 1a. Then, the jet flow from the upper jet nozzle 2 in FIG. 1a stops. In this way, when the controller 9 rotates the rotor 8b of the switching valve 8 alternately by 90 degrees left and right at intervals of 1 to 10 seconds, the two jet nozzles operate in opposite directions to emit a jet stream. This state of repeated stopping and stopping can be illustrated in an easy-to-understand way.
As shown on the right side of FIG. 1(a), if the timing of rotation of the rotor 8b is controlled at time t (1 to 10 seconds), the injection pattern shown in FIG. 1(a) is repeated.

In this embodiment, the switching valve 8 was provided only in the jet nozzle 2 on the right side of FIG. It is something. Normally, when taking a bath with jet bubbles, it is generally preferable to apply the bubbles to the lower back to perform a lumbar massage than to apply the bubbles to the soles of the feet, and this example is in line with that practical example. .

Effects of the Invention As is clear from the above explanation, the present invention uses an electric switching valve to switch and eject water streams from a plurality of jet nozzles close to each other at predetermined intervals. The stimulation appears as a change in strength. For example, when used for pine surgery on the lower back, stimulation is alternately applied to the left and right sides of the lower back with different strengths, which significantly improves blood circulation in the human body and improves pine surgery. The effect can be increased. In addition, as a switching means, instead of a solenoid valve, which is unsuitable for long-term use because the water flow rate is excessive before and after the valve closes, causing severe wear and tear on the valve seat, we have installed an electric switching valve that alleviates these problems. Since it is used, investment costs and maintenance costs can be reduced.
