Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bubble pine surge device that generates a bubble jet in water.

[Conventional technology]

Conventionally, water (including hot water) from the bathtub is sucked in by a pump, and on the discharge side of the pump, this water is mixed with air introduced from the outside, and the mixture is jetted into the bathtub as a jet of bubbles.
A so-called ultrasonic bubble pine surge device has been put into practical use.

In addition, some of these bubble pine surge devices include, for example, Japanese Utility Model Application No. 57-130630 and Japanese Patent Application Publication No. 63-5747.
As disclosed in the above publication, in addition to providing a bubble jet outlet on the device main body side, a flexible hose is detachably connected to the device body so that the bubble jet is also ejected from the hose. There is something.

This hose connection type has the advantage that even when the body is far from the main body of the device, the bubble jet can be applied to the local part of the body using the hose, so local pine surgery can be performed freely.

[Problem to be solved by the invention]

By the way, the hose connection type bubble pine surge device does not simply require attaching a flexible pipe to the bubble jet port of the main body; in other words, it is not enough to simply attach a hose that guides the bubble jet to the bubble jet port of the main body. In this case, the air bubbles mixed with water and air will separate into water and air due to the difference in specific gravity during the process of passing through the hose before the bubble jet is ejected from the hose tip, reducing the jetting force and causing the pine surge effect. is reduced.

Therefore, in the above-mentioned conventional technology, in view of this point, for example, in the device disclosed in Japanese Utility Model Application Publication No. 57-130630, the hose is connected to the pump discharge side.

The water from the pump is guided to a nozzle provided at the end of the hose, and an air introduction hole is provided in this nozzle to mix water and air at the end of the hose. In the device, a water passage and an air passage are concentrically formed in the hose, the water discharged from the pump is passed through the water passage, and the air from the air intake pipe provided on the main body is guided into the air passage. Therefore, consideration has been given to mixing the air and water at the nozzle at the end of the hose.

However, among these conventional technologies, the former method in which the air introduction hole is formed in the nozzle part at the end of the hose is designed to prevent water from entering the air introduction hole at the end of the hose. There are restrictions such as having to expose the area above the water surface.

In addition, in the case of the latter type in which the water passage and air passage are concentrically formed in the hose, the hose connection part on the device main body side has a connecting part for connecting the water passage of the hose to the pump discharge port. However, the outlet for connecting the hose on the main body side could not function to eject a jet of bubbles by itself when the hose was not connected. Therefore, in the latter case, separate from the outlet of the hose connection part, it is necessary to secure an outlet for ejecting the bubble jet when the hose is not in use. This tends to complicate the structure of the piping system within the main body.

The present invention has been made in view of the above points, and its purpose is to provide a hose connection type pine surge device in which when the hose is removed, the hose connection part on the device body side will emit a jet of air bubbles. When the hose is connected, the tip of the hose is structured to eject a jet of air bubbles, making it possible to perform an effective air bubble pine surge depending on the application in any case, and when the hose is connected. The object of the present invention is to provide a pine surge device that is easy to use and handle by allowing the tip of the hose to be submerged in water.

[Means to solve the problem]

The present invention is configured as follows to achieve the above object.

Hereinafter, in order to facilitate understanding of the content of the present invention, the description will be made with reference to the reference numerals of the embodiments shown in FIGS. 1 and 4.

The first problem-solving means is a bubble pine surge device that sucks water (hot water) in the bathtub with a pump, mixes this water with air introduced from the outside, and squirts the mixture into the bathtub as a bubble jet. As shown in FIG. 1, a nozzle A is disposed on the pump discharge section 24b side and in the discharge pipe line 24b'.

An air introduction pipe 31 is provided immediately downstream of the nozzle A and is connected to join the discharge pipe 24b'.

A first ejection part Jl is set to mix and eject the air guided through the air introduction pipe 31 and the water that has passed through the nozzle A, and a hose connection part 2 is connected to this first ejection part Jl.
7 and a flexible hose 35 that is detachably connected to the hose connection part 27, and when connected, this hose 35 is connected to the water passageway leading to the discharge pipe 24b' of the first jetting part Jl. 35a and this water passage 3
A nozzle B disposed at the tip of the hose 35 and an air passage 35b branched from the air introduction pipe 31 to introduce air to the tip side of the hose are provided. A second jetting part J2 is set to mix the water that has passed through and jet it out, and furthermore, the air introduction pipe 31 is connected to a valve mechanism 4 that switches the passage.
0.41, when the hose 35 is disconnected, it communicates with the discharge pipe line 24b' of the first spouting part Jl, and when the hose 35 is connected, it communicates from the air passage 35b of the hose 35 with the second spouting part J2. It becomes a structure.

The second problem solving means is configured as follows as an alternative to the first problem solving means.

That is, as shown in FIG. 4, the nozzle A disposed in the discharge pipe 24b' is connected to the pump discharge part 24b so as to join the discharge pipe 24b' immediately downstream of the nozzle A. A first air introduction pipe 31-1 is provided, and a first ejection part Jl is provided that mixes the air guided through the first air introduction pipe 31-1 and the water that has passed through the nozzle A and ejects the mixture. At the same time, this first spouting part Jl is provided with a hose connection part 27, and is provided with a flexible hose 35' that is detachably connected to the hose connection part 27, and this hose 35' is connected to the hose connection part 27. and a waterway 35a' which sometimes leads to the discharge pipe 24b' of the first spouting part.

A nozzle B arranged at the tip of this water passage 358' and a second air introduction pipe connection part 31-2 connected to join the water passage #&358' of the hose downstream of this nozzle B.
A second ejection part J2 is set, which mixes the air led from the second air introduction pipe 31-2 and the water that has passed through the nozzle B and ejects the mixture.

Furthermore, the first. The second air introduction pipe 31-1, 31-2 is connected to the first air introduction pipe 31 when the hose 35' is not connected.
-1 opens its conduit, and when connecting the hose 35', closes the conduit of the first air inlet pipe 31-1, and closes the conduit of the second air inlet pipe 31-1.
The structure is such that the pipe line 2-2 is open.

[Effect]

According to the first problem solving means, the following effects are achieved.

When the hose 35 is disconnected during operation of the device (when the pump is driven), the valve 40 is open and the valve 41 is closed. Therefore, the air introduction pipe 31 communicates with the discharge pipe line 24b' of the first ejection part Jl.

In this case, the water sucked in by the pump is transferred to the discharge pipe 24.
After passing through the nozzle A of b' and increasing the flow velocity at the nozzle A, it merges with the air led from the air introduction pipe 31 downstream of the nozzle A, and the water and air are mixed to form bubbles. This bubble jet is ejected into the bathtub via the I-th ejection part Jl.

On the other hand, the hose 35 is connected to the hose connection part 2 of the first spouting part Jl.
7, the water passage 35a of the hose 35 communicates with the discharge pipe 24b' of the first spouting part Jl. Further, the valve 40 is closed and the valve 41 is opened. Therefore, the air introduction pipe 31
is the air passage 3 of the hose 35 instead of the first jetting part Jl.
5b leads to the second jetting part J2.

In this case, the first jetting part Jl does not introduce air, so it simply becomes a water passage on the pump discharge side.
The water passing through here passes through the water passage 35a of the hose 35,
Increase the flow rate of the water stream with nozzle B, and
reaches the jetting part J2.

In addition, at this second spouting part J2, the water that has passed through the nozzle B and the air introduction pipe 31. The mixture is mixed with the air introduced through the air passage 35b, and is ejected from the tip of the hose 35 into the bathtub as a jet of bubbles.

By performing this operation, when the hose is disconnected, a jet of bubbles is issued from the pump outlet side of the device body into the bathtub (the jet of bubbles in this case is useful when you want to apply the bubble jet to the entire body, ), and when connecting the hose,
Even if the body is far from the main body of the device, the bubble jet formed at the tip of the hose can be applied to the body without reducing the jetting force, and a localized bubble massage can be performed effectively.

Next, the operation of the second problem solving means will be explained.

First, when the hose 35' is disconnected, the same operation as in the first problem-solving means is performed, and a jet of air bubbles flows into the bathtub via the first jet part Jl set on the pump discharge part 24b side of the device main body. It is squirted inside.

That is, the bubble jet in this case flows through the pump discharge pipe 24.
The water that has passed through the nozzle A of b′ and the first air introduction pipe 31
-1 is mixed with the air introduced through the first jetting portion Jl to form the first jetting portion Jl.

Next, when the hose 35' is connected to the hose connection part 27 in the first spouting part Jl, the hose water passage 35a'
is connected to the discharge pipe line 24b' of the first jetting part Jl. In this case, the second air introduction pipe 31-2 connected to the distal end of the hose 35' so as to join downstream of the nozzle B is opened. The first spouting part Jl simply serves as a water passage, and water flowing there passes through the nozzle B from the water passage 35a' of the hose 35'. Then, the bubble jet is mixed with the water after passing through the nozzle B at the second spouting part Jl at the end of the hose.
The bubbles are mixed with the air introduced through the air introduction pipe 31-2, and this bubble jet is ejected from the tip of the hose.

Similarly to the first problem solving means, in this problem solving means, when the hose is not connected, a jet of air bubbles is emitted from the pump discharge part side of the device main body into the bathtub, and when the hose is connected, the body is exposed to the device. Even if you are far away from the main body, the bubble jet formed at the end of the hose can be applied to your body without reducing the jetting force.

Reference numerals 2 and 43 are valve holders for check valves, which have a large number of through holes.

Next, the operation of this embodiment will be explained.

When using a pine surge device, the suction ball 34.
The air intake pipe 33 is placed outside the bathtub.

When the push button 19 is pressed, the reed switch 2 in the control circuit 6 is activated.
1 is turned on, and the pump 22 is operated.

Then, when the hose 35 is in the disconnected state, the primary operation is performed.

The water sucked from the bathtub by the drive of the pump 22 is
As shown in FIG. 1, it passes through a nozzle A arranged in a conduit 24b' of a pump discharge section 24b.

In this case, in the first spouting part Jl, negative pressure is applied to the check valve 40 by the flow of water, and as a result, the check valve 40 opens the air hole 30a, while the check valve 41 opens the air hole 30a. Close the air hole Sob.

Therefore, the intake ball 34. Air passing through the air intake hole 33° and the air introduction pipe 31 is guided to the first jetting portion Jl (in other words, to the discharge pipe 24b' side) via the air hole 30a.

In the first ejection part Jl, these air and water are mixed to form a bubble jet, and this bubble jet flows into the diffuser 2.

into the branch 30'.

By connecting the hose, the waterway 35a of the hose 35 communicates with the discharge pipe 24b' of the first spouting part Jl.

Then, when the pump is driven, the water sucked by the pump is transferred to the pump discharge pipe 24b', the nozzle A, the diffuser 28. The water passage 35a of the hose 35 passes through the nozzle B, and the presence of the nozzle B increases the water pressure in the discharge pipe 24b' upstream of the nozzle B, which causes the check valve 40 to close the air hole 30a. , On the other hand, due to the negative pressure generated by water passing downstream of the nozzle B at the tip of the hose 35, the check valve 4

In this case, the first jetting part Jl does not introduce air and simply serves as a water passage on the pump discharge side, and the water passing through it passes through the water passageway 35a of the hose 35, and the nozzle B increases the flow velocity. Then, it reaches the second spouting part J2 at the tip of the hose. In addition, the intake ball 34° air intake pipe 33. Air introduction pipe 31

In the second ejection part J2, the air and water guided as described above are mixed to form a bubble jet, and this bubble jet C is ejected into the bathtub via the diffuser 37.

According to this embodiment, the following effects are achieved.

(a) When the hose is not connected, a jet of air bubbles is ejected from the hose access port 27 provided on the main body, and when the hose is connected, a jet of air bubbles is formed at the end of the hose J2, and the air bubbles are ejected vigorously from the end of the hose. can. Therefore, whole body pine surgery and local pine surgery can be performed by simply attaching and detaching the hose, and since local pine surgery is performed using a hose, the bubble injection force is reduced even when the body is far from the main body of the device. It can be done effectively without causing any problems.

(B) Also, as mentioned above, the hose connection port 27 can also be used as the bubble jet port 28 when the hose is not connected, so the hose connection port and the first bubble jet port to be provided on the main body side can be adjusted. By using only one pump, the piping structure of the pump discharge pipe can be simplified, and the product can be made more compact and lower in cost.

(c) When using a hose connected to the pine surge device body, the air to be introduced into the end of the hose is guided through the air passage 35a provided in the hose 35 in the air introduction pipe 31 on the device body side. Therefore, even if the entire hose is submerged in water, it is possible to form a bubble jet, and it is possible to provide a pine surge device that is convenient to handle and easy to use.

(d) Selection of air introduction when the hose 35 is connected or disconnected (selection of air introduction to the first ejection part Jl and the second ejection part J2) is performed by the valve mechanism 40.41, In this case, switching of the opening and closing of the valve mechanism 40.41 is performed using the discharge pipe 24.
A special valve is used to utilize the negative pressure generated when water passes through b', the increase in water pressure when the hose is connected, the negative pressure caused by air passing through the air introduction pipe 31, the negative pressure generated when water passes through the end of the hose, etc. There is no need to provide a swinging mechanism, and the structure can be simplified and costs can be reduced accordingly.

(e) In this embodiment, air is taken in using the intake ball 34, and since the intake ball 34 has a wide opening for air intake, the generation of air passing sound that occurs when air is taken in is reduced. It is possible to provide a device with low noise.

Next, a second embodiment of the present invention will be described with reference to FIG.

FIG. 4 is a sectional view showing the hose connection state of this embodiment, and the same reference numerals as those of the first embodiment described above indicate the same or common elements.

Here, the explanation will focus on the points that are different from the first embodiment.

In this embodiment, as in the first embodiment, the nozzle A is arranged in the pump discharge pipe 24b' on the side of the device main body l, and the first air is directly downstream of the nozzle A so as to merge with the pipe 24b'. The air introduction pipe connecting portion 30 is connected to the introduction pipe 31-1.
-1, only the check valve 40 is arranged, and the air introduction pipe connection part 30-1 does not have the air passage connection branch part 30' on the hose side as in the first embodiment. The first air introduction pipe 31-1 is connected to the intake ball 34 via the air intake pipe 33 as in the first embodiment.

Furthermore, the hose 35' connected to the hose connection part 27 has only a waterway 35a' formed therein.

A nozzle B is arranged at the distal end of the hose, and a second air introduction pipe 31-2 is connected downstream of the nozzle B via a connecting portion 30-2 so as to merge with the water passage of the hose.

The second air introduction pipe 31-2 has the same structure as the air intake pipe 38 of the first embodiment, and has an intake ball 34' at its upper end.
will be placed.

In this embodiment, the diff user 37 formed at the tip of the hose serves as the second spouting portion J2.

According to the present embodiment, when the hose is not connected, the water that has passed through the nozzle A and the first air introduction pipe 31-1. The mixture is mixed with the air introduced through the air hole 30a, and the mixture is ejected as a bubble jet from the first ejection part Jl.

When the hose is connected, water discharged from the pump passes through the discharge pipe 24b' and the nozzle B of the passage 35a of the water hose 5, but in this case, the water pressure upstream of the nozzle B increases,
The check valve 40 closes the air hole 30a of the first air introduction pipe 31-1 provided on the device main body side. And the hose tip 37
Due to the negative pressure generated by the passage of water on the side, air flows into the second air introduction pipe 31-2 at the diffuser 37 at the end of the hose.
This air is mixed with the water that has passed through the nozzle B to form an air jet that is ejected into the bathtub.

Therefore, this embodiment also provides the same effects as the first embodiment. Note that the effect (c) of the first embodiment is the same as that of the second embodiment.
In the embodiment, it is satisfactory to expose the upper part of the second air introduction pipe 31-2 to the water surface. Furthermore.

In this embodiment, it is sufficient to use one check valve for controlling air introduction. Note that the first air introduction pipe 31-1 and the second air introduction pipe 31-2 may be of a dual-purpose type. in particular,
When connecting a hose, the air intake pipe 33 with an intake ball (see FIGS. 2 and 3), which becomes a part of the first air introduction pipe 31-1, is removed from the hose connection part 32 on the top of the case.
This can be connected to the branch connection part 30-2 at the tip of the hose as the second air introduction pipe 31-2 when the hose is connected.

In this way, the number of parts of the air introduction pipe can be reduced, which is economical.

In each of the above embodiments, the valve mechanism that opens and closes the air introduction pipe is driven by negative pressure caused by air passing through the air introduction pipe, negative pressure caused by water passing through the end of the hose, or water pressure generated within the hose. Although this is done by using a rise, it is also possible to open and close the valve mechanism manually or by using the insertion force of a hose.

〔Effect of the invention〕

As described above, according to the present invention, when the hose is removed, the hose connection part on the device main body side blows out air bubbles,
When a hose is connected, a jet of bubbles is formed and ejected at the tip of the hose, so effective bubble pine surge is possible in any case. Furthermore, when the hose is connected, it is possible to perform localized pine surges while separating the body from the main body of the device, and even if the entire hose is submerged in water, air can be introduced and bubble jets can be formed without any problems, making it easy to use and handle. We can provide you with a good pine surge device.
