Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a jet device for baths.

2. Description of the Related Art Conventionally, there has been a jet device as shown in FIG. That is, a pump 32 is installed outside the bathtub 31, sucks hot water in the bathtub 31 through a suction pipe 32, and sends pressurized water to a spout part 34 attached to the side of the bathtub 31 through a discharge pipe 33. It was configured so that pressure water mixed with air bubbles was injected from the ejection part 34. The structure of the ejection part 34 is shown in FIG. The high-pressure water sent from the discharge pipe 33 is injected from the nozzle 35 and is ejected from the outlet of the venturi 36 to the outside.

Since there is a negative pressure near the entrance of the venturi 36, air is taken in from the air intake pipe 37, mixed with the water discharged at the entrance of the venturi 36, and injected into the bathtub 31. Further, the root portion 38 of the venturi 36 is spherical, and the venturi 36 is attached so as to be rotatable to some extent, so that the injection angle can be changed.

Problems to be Solved by the Invention However, although this configuration allows the spray angle to be changed to some extent, in order to apply the jet stream to various parts of the body, it is necessary to move the body to bring the desired part closer to the jetting part. It was very inconvenient.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a jet device that can freely apply a jet to a desired portion.

Means for Solving the Problems The present invention provides a flexible pipe with two passages, one for water and one for air, and a mixing nozzle for mixing water and air and ejecting the mixture at the tip of the flexible pipe. It is installed.

Operation By attaching the mixing nozzle to the tip of the flexible pipe, the user can grasp the mixing nozzle and move it freely to easily bring the mixing nozzle close to the desired area.

EXAMPLE Hereinafter, a jet flow device according to an example of the present invention will be described. In FIG. 1, 1 is a hose provided with two passages, a water ring passage and an air-only passage, and 2 is a spout section provided at the tip of the hose 1, which mixes water and air and jets them out. 3 is a coupler provided in the bathtub 4 and coupled to the base of the hose 1. 5 and 6 are water supply pipes that introduce water pressurized by a pump 7 into the bathtub 4. A coupler 3 is connected to a water supply pipe 5 on the outside of the bathtub 4. Further, numeral 8 denotes a spout section which is attached to the bathtub 4 as in the case of the conventional example and which mixes water and air and spouts the mixture into the bathtub 4. Spout part 8
A water supply pipe 6 is connected to. Reference numerals 9 and 10 are electromagnetic valves provided in the water supply pipes 5 and 6, respectively, for opening and closing the water channels. 11 is a switch for operating the pump 7 and electromagnetic valves 9 and 10; 12 is a water suction pipe that leads water from the bathtub 4 to the inlet of the pump 7;

Next, a more detailed explanation will be given based on FIG. 2.

The hose 1 has two passages, one for water and one for air, as described in A above. That is, 13 is a water passage formed in the center, and 14 is an air passage formed coaxially around the water passage. 15 is a venturi attached to the tip of the hose 1, and 16 is a mixing chamber formed inside the venturi 15 for mixing water and air. Reference numeral 17 represents a jet port for jetting water and air to the outside from the mixing chamber, and reference numeral 18 represents an air intake port for taking air into the mixing chamber 16. 19 has a tip extending from the rear of the venturi 15 to the mixing chamber 16
This is a nozzle that protrudes inward. The venturi 15 is fitted and fixed in the outer tube 21 at the tip. A root portion of the nozzle 19 is connected to an inner tube 20.

22 is a joint for connecting the hose 1 to the coupler 3. 23 is a water conduit formed in the center of the joint 22, and 24 is a plurality of air intake holes formed distributed around the water conduit 23. Reference numeral 25 denotes a connecting portion that connects to the inner tube 20 of the hose 1 that protrudes around the water conduit outlet, and 26 denotes an outer tube 21 that protrudes so as to surround all the air intake holes 24.
This is the connecting part that connects with. Reference numeral 27 denotes a coupling portion that protrudes from the center of the outer end surface of the joint 22 and is coupled to a coupling tube 28 provided at the center of the coupler 3. Reference numeral 29 denotes a gasket provided on the inner side of the connecting portion 27 to connect it to the connecting tube 28 without leaking water. 30 is an air intake pipe connected to the interior of the coupler 3 so as to communicate therewith.

The outer part of the joint 22 is threaded with a male thread, and the inner part of the force coupler 3 is threaded with a female thread. When attaching the joint 22 to the coupler 3, first fit the coupling part 27 and the coupling pipe 28 of the coupler 3gq, and then rotate the threaded part to the female threaded part of the coupler 3. Screw it in and tighten.

Although the coupling tube 28 of the coupler 3 is not shown in FIG.
It is connected to the water supply pipe 5 mentioned above. Coupling 22 to coupler 3
When attached, the water supply pipe 5 and the waterway 13 of the hose 1 communicate with each other, and the air intake pipe 30 and the air passage 14 of the hose 1 communicate with each other.

Next, the operation of the jet device configured as described above will be described. When the pump 7 pressurizes and sends water, the water flows into the water passage 13 in the hose 1. Then, it is vigorously discharged from one nozzle into the mixing chamber 16,
Furthermore, it is ejected to the outside from the ejection port 17 of the venturi 15. As the water is forcefully discharged from the nozzle 19, the inside of the mixing chamber 16 becomes negative pressure, and air is taken into the mixing chamber 16 through the air intake pipe 30, the hole 24 of the joint 22, and the air passage 14 of the hose 1. Then, together with the water ejected from the nozzle 19, the bubbles are ejected from the ejection port 17 to the outside.

The user can grasp the spout 2 at the tip of the hose 1 and move it freely, and can easily apply it to the desired part, such as the ankle or thigh. You can also take pictures up close.

Further, when not bathing, the inside of the bathtub 4 can be cleaned, and the spouting part 2 can be taken out to the outside of the bathtub 4 to be used for cleaning various parts in the bathroom.

In addition, when this jet jet device is not used, the joint 22
It can also be removed from the coupler 3 by rotating it.
It is possible to store it in another location.

In this embodiment, a case has been described in which the pump 7 is installed under the floor of a bathroom, but it is also possible to implement an embodiment in which a portable pump is placed in the bathroom. In this case, a hose is connected to the inlet of the pump, and the hose is placed inside the bathtub to draw in water. Then, a coupler similar to the coupler 3 in the previous embodiment is provided at the ejection part of the pump, and the hose 1 is attached thereto by a coupling 22. In this case, the user pulls the hose 1 into the bathtub from outside the bathtub and uses it by holding the spout section 2 at the tip. In this embodiment, there is no need to install a dedicated pump in the bathroom or to install suction and ejection pipes in advance (it can also be used in a normal bath other than a jet bath).

Effects of the Invention The present invention provides a flexible pipe with two passages, one for water and one for air, and a mixing nozzle that mixes water and air and sprays it out at its tip. The nozzle can be held and moved freely, and the mixing nozzle can be easily brought close to the desired area to apply the jet stream.
