Description

[Detailed description of the invention] TECHNICAL FIELD This invention relates to improvements in jet bath equipment.

BACKGROUND ART Conventionally, in a jet bathtub, when a jet stream is generated by injecting a jet stream from an injection nozzle into bath water in a bath, there are two types of jet stream: one by vortex injection and one by bubble injection.

Whirlpool jetting is a method in which only a stream of water that does not contain any air bubbles is sprayed forcefully, and with bubble jetting, air is sucked into the water stream sprayed at the injection nozzle, and this air is mixed into the water stream, causing water to flow into the bath water. A stream of water mixed with air bubbles is injected into the area.

Traditionally, whirlpool bathtubs have both vortex jets and bubble jets.
・There are some types of jet bathtubs that can spray water, but the whirlpool jet method that is generally adopted in such jet bathtubs closes the air inlet to spray only the water stream, preventing air from getting mixed into the water stream. be.

Therefore, a negative pressure is generated in the air outlet portion facing the hot water outlet by the water stream injected from the hot water outlet, and the force of the injected water stream is extremely reduced due to the influence of this negative pressure.

The purpose of this invention is to increase the water force during whirlpool jetting to the same level of strength as bubble jetting in a jet bathtub using a jet nozzle that can perform both whirlpool jetting and bubble jetting, thereby improving the whirlpool jet bath performance. The upstream side of the air suction path connected to the air inlet of the injection device is connected to inhale dry water in the bathtub, and the air suction pipe is connected to an appropriate location of the air suction path via a switching valve. By connecting them, it is possible to obtain vortex jet and bubble jet with approximately the same water force just by opening and closing the operation valve.

Next, the present invention will be explained in detail with reference to illustrated embodiments.

In the illustrated embodiment, a jet device 1 suitable for carrying out the invention is attached to a side wall 21 of a jet bath 2 .

The jet device 1 includes a plurality of air/hot water discharge ports 4 along the outer periphery of a hot water nozzle 3 having a drought discharge port 31 extending in the axial direction.
A cap 4 is coaxially fitted with the hot water outlet 31 and the hot water outlet 31 and the air/dry water outlet to the flexible nozzle 5 facing the inside of the bathtub 2. 41 is connected to the side wall of the bathtub 2.To attach it to the side wall of the bathtub 2, screw the washer T-12 into the casing 11 and fit the seal 13.13 to make it watertight. In the figure, numeral 14 is a decorative cover;
Reference numeral 42 denotes a seating surface for the flexible nozzle 5 provided on the cap 4, and the flexible nozzle 5 can freely change direction in either the vertical or horizontal directions. The cap 4 is pressed toward the universal nozzle 5 by the coil spring 43, so that the seat surface 42 comes into contact with the universal nozzle 5. Furthermore, the adjustable nozzle 5 is held watertight by an O-ring 51.

On the upstream side of the hot water nozzle 3 and the cap 4, a dry water intake 32 and an air/hot water inlet 44 are installed, respectively. The downstream ends thereof are connected to a drought circulation path 6 and an air/hot water intake path 7, respectively.

The upstream end of the hot water circulation path 6 and the air/hot water intake path 7 is the bathtub 2.
It is connected to the lower side of the hot water circulation path 6, and in the path of the hot water circulation path 6,
A circulation pump P is arranged, and based on the circulation pump P, the bath in the bathtub is forcibly circulated through a hot water circulation path 6.

Further, an air supply pipe 8 is connected to the air/hot water intake pipe 7 via a switching valve 81, and the upstream end of this air supply pipe 8 is an air intake port 82. By operating the switching valve 81, bath water or air is selectively supplied to the air/hot water inlet.

Next, to explain the operation, when the circulation pump P is operated to take the bath water in the bathtub 2 into the hot water circulation path 6 and forcefully circulate it, the bath water is forced to flow through the hot water supply 32 to the hot water nozzle 3. , the hot water is spouted from the hot water outlet 31 to the adjustable nozzle 5. This ejection causes the hot water nozzle 3 to
A negative pressure is generated in the surrounding air/hot water outlet 41, and this negative pressure starts the circulation of the air/hot water intake passage 7.
When performing a bubble jet bath, it is sufficient to open the switching valve 81, whereby the air sucked from the air intake port 82 flows into the air/hot water intake path 7 through the air supply pipe 8, and the air/hot water is Air/drought outlet 4 from population 44 to cap 4
1, the hot water 11 merges with the drought jet spouted from the outlet 31, passes through the adjustable nozzle 5 in the form of a bubble jet, and is jetted into the bathtub, creating a bubble jet bath.

In addition, in order to perform a vortex jet bath by vortex injection, by switching the switching valve 81 of the air supply pipe 8, the supply of air is stopped, and the air is sucked into negative pressure and the air/hot water suction pipe 7 is filled with dry water. Similarly to the circulation path 6, the bath water taken from the bathtub 2 flows through the air/hot water inlet 44 and flows to the air/hot water outlet 41, where it merges with the drought jet spouted from the hot water nozzle 3, forming a vortex jet. The water is sprayed into the bathtub from the flexible nozzle 5hX. On this occasion,
What is particularly noteworthy is that the water generated by the injection from the hot water nozzle 3 (the negative pressure inside the air/hot water outlet 41 around the drought nozzle is sucked in from the air/hot water outlet 44) is canceled out by the hot water. The water force jetted from the nozzle 3 does not show any decline and is jetted with the same force as bubble jetting.

As described above, according to the present invention, when performing vortex injection, hot water is introduced into the air/drought inlet instead of air intake in bubble injection, so that the negative pressure generated around the hot water nozzle is reduced. This problem can be solved by inhaling this hot water, thereby making it possible to perform vortex jetting with the same water force as bubble jetting.
