Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bubble bath device that obtains a pine surge effect by ejecting a stream of bubbles toward a bather.

[Prior art]

Conventionally, in this type of bubble bath device, the water absorption part and the bubble flow jetting part are connected through a bathtub water circulation path having a circulation pump, and the bathtub water circulation path is separate.
A bubbly water circulation path is connected to the water absorption part and the bubbly flow spouting part, and the bubbly water circulation path is equipped with an on-off valve for air supply and an adjustment valve to adjust the bubble flow rate, thereby creating a bathtub water circulation path. There is known a system in which a bubble flow flowing down a bubble water circulation path is mixed with a main circulation flow flowing down inside, and the mixture is jetted from a bubble water spouting part (Japanese Patent Application Laid-Open No. 135058/1983).

[The problem that the idea aims to solve]

However, in the case of the prior art, the line configuration is such that the bubble flow flowing down inside the bubble water circulation path is mixed into the main circulation flow flowing down the bathtub water circulation path, so the amount of air bubbles mixed in is smaller than the main circulation flow. Due to the increased amount, there is a risk that the flow rate per unit of the jet flow (bubble flow) will inevitably decrease. Although it is possible to increase or decrease the amount of air bubbles by adjusting the amount of air with the air supply on-off valve or the bubble flow rate with the adjustment valve, pine surge The range of wave strength selection is extremely limited, making it impossible for bathers to freely enjoy the pine surge waves they desire. Also, since the pine surge wave is set to the same strength for both the foot side bubble flow jetting part and the dorsal side bubble flow jetting part, for example, if you want to increase the strength of the pine surge wave on both the foot side and the back side, you can Inside,
It is not possible to adapt to various situations such as when you want to perform pine surgery on only the private parts, or when you want to add strength to the pine surgery, or when you want to perform pine surgery only on the legs or back, and it is not possible to meet the diversifying needs of bathers. . Since it is necessary to route two routes, a bathtub water circulation path and a bubble water circulation path, the piping configuration becomes complicated and the equipment cost increases. etc., causing various problems.

By the way, in order to solve the above-mentioned problems, as disclosed in Japanese Utility Model Application Publication No. 52-105541, a device (opening/closing valve) for varying the flow path area is installed in the bathtub water circulation path. However, due to the root cause of the system in which the main circulation flow joins the bubble water circulation path and increases the volume, it is unavoidable that the amount of air bubbles mixed in is small compared to the jet flow rate, resulting in pine surge. The selection range of wave strength is still limited to a limited range, and although it is possible to select ON or OFF of the bubble flow jet, it is possible to change the strength only partially on the inside or local part of the legs or back. Of course, it is not possible to perform pine surgery on the foot side or dorsal side individually, and the wiring configuration remains complicated, so it is not a fundamental solution.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to expand the selection range of the strength of pine surge waves, and to be able to locally change the strength of pine surge waves on the foot side or back side. Or perform pine surgery on the foot side or dorsal side individually,
To provide a structurally simple bubble bath device that can meet the needs of various bathers.

[Means to solve the problem]

The technical means taken to achieve the above technical problem was to connect the water absorption part provided in the bathtub, several foot-side bubble flow jetting parts, and a back-side bubble flow jetting part to a circulation path having a forced circulation means. In the bubble bath device, an air supply unit is connected to each of the bubble flow jetting portions, and the air supply portion sucks air by a negative pressure action of the jetted water jetted from the jetting portion and mixes it into the jetted water. The downstream portions of the foot side passage and the dorsal side passage constituting the circulation path portion downstream of the means are constituted by subdivision passages that communicate with each of the foot side bubble flow spouting portions and the dorsal side bubble flow spouting portions,
Each of the sub-channels is equipped with a channel restricting device that variably adjusts the channel area, and the foot-side channel and dorsal-side channel are
The gist is that it can be opened and closed using the installed on-off valve.

[Effect]

According to the above-mentioned technical means, a flow passage throttling device is installed in each of the subdivisions of the foot-side tract and the dorsal tract that communicate with several foot-side bubble flow jetting parts and several dorsal-side bubble-flow jetting parts. , the flow area of the desired sub-channel can be freely varied, and the flow rate, which is a factor in the amount of air sucked from the air supply section, can be varied. When the flow rate is high, a large amount of air is sucked in from the air supply section due to the negative pressure effect, creating a bubble flow with a strong pine surge effect. In addition, when the flow rate is slow, the negative pressure effect does not work as much, creating a bubble flow that is gentle on the skin and contains a small amount of air. Further, the on-off valves for the foot side passage and the dorsal side passage can freely stop the bubble flow from the foot side or dorsal side bubble flow spouting portion.

[Effect of idea]

As described above, the present invention is equipped with a flow restricting device in each of the sub-channels that communicate with several foot-side bubble flow jetting parts and several dorsal-side bubble flow jetting parts, and an on-off valve is installed upstream of the flow restricting device. Furthermore, since it is installed, the amount of mixed air is automatically varied by the suction action of the flow rate that is variable by the flow path restrictor, and pine surge waves of various strengths are ejected. Therefore, since the circulating water sent to each bubble flow jetting section changes the amount of air mixed in with its own flow velocity, unlike the prior art method in which bubble flow is mixed into the main circulation flow, a flow path throttling device is required. The amount of air mixed in can be freely adjusted by simply adjusting the aperture rate, that is, the opening degree of the flow path, and a variety of strengths and weaknesses of the pine surge waves can be selected reliably and accurately, making it effective for everyone from the elderly to children. Moreover, unlike the prior art in which bubbles of the same strength are ejected from all the ejection parts, bubbles are ejected from the foot side or dorsal side, from both sides (foot side and dorsal side), and even partially on the foot side or dorsal side. Not only can you switch the bubble flow from the jetting part, but you can also freely select the strength of the jet.For example, you can apply a stronger pine surge to an area with muscle pain than other pine surge areas, or prevent an injured area from being exposed to the pine surge wave. It can be adjusted on the spot to suit each bather's unique usage and physical condition. Furthermore, although the pine surge bath and general ablution bath can be used in common, it is simpler and can be provided at a lower cost than the prior art having two routes.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

The drawing shows a foam bath device.

The bubble bath device of this embodiment has a forced circulation means ( (hereinafter referred to as a circulation pump) 3a, and the leg portion of the circulation path 3 downstream of the circulation pump 3a is branched into foot side bubble flow spouting sections 2, 21 and dorsal side bubble flow spouting sections 2, 22. A subdivision consisting of a side passage 4 and a dorsal passage 4, and connecting the downstream portions of the foot side passage 4 and dorsal passage 4 to the foot side bubble flow jetting parts 2, 21 and the dorsal side bubble flow jetting parts 2, 22. Road 4', 4', 4',
4', each of the sub-channels 4', 4', 4', 4' is equipped with a flow restricting device C, and the leg side passage 4 and dorsal side passage 4 can be opened and closed by an on-off valve B. This is what I did.

Although not described in detail, each of the bubble flow jetting parts 2, 21, and 22 includes a constriction part (not shown) that constricts one channel when a circulating flow is supplied by the action of the circulation pump 3a, and a constriction part (not shown) It has a general structure in which a jet stream is spouted after being throttled by a (not shown), and at the same time as the jet stream is jetted out, air is supplied by negative pressure action at the time of jetting out, and air is mixed in the air supply section F. (air supply pipe) is connected to the upstream side of the throttle part (not shown), and two air supply pipes are connected to the backrest side wall a1 and the foot side wall a2, respectively.
They are arranged in parallel relationship. The bubble flow jetting parts 2, 21, 22 connect the circulation path 3 downstream of the circulation pump 3a to the backrest side wall a1 side and the foot side wall a2 side.
At the tip of the foot tract 4, which branches into two dorsal tracts 4 to the sides, and further branches into two subdivisions 4', 4', 4', 4' from the dorsal tract 4. installed.

The on-off valve B is of an electromagnetic type, and has the function of opening and closing the foot side passage 4 and the dorsal side passage 4 to send circulating flow to the respective bubble flow jetting portions 2, 21, and 22 as necessary, It is electronically or electrically linked via a controller E so that it can be opened and closed by touching a touch switch on an operation panel D disposed on the upper edge surface a3 of the bathtub.

The flow path throttling device C is a motor valve c, which is installed in the middle of each of the sub-channels 4', 4', 4', 4'.

This motor valve c is connected to each subdivision 4', 4', 4',
This is to adjust the water pressure of the circulating flow by varying the flow path area of 4', and by touching the switch for selecting the degree of restriction provided on the operation panel D, the valve body rotates at a predetermined selected angle. It is electrically or electronically linked to the throttling degree selection switch via a controller E so that a selected flow pressure can be obtained by moving the water pressure.

The operation of the bubble bath device in this embodiment will now be explained.

The circulation pump 3a is operated via the controller E by touching the touch switch provided on the operation panel D, and at the same time, one of the on-off valves B provided in the leg side passage 4 and dorsal side passage 4 is activated. Alternatively, a bubble stream is ejected from each bubble stream jetting section 21, 22 by operating both of them by touching a touch switch to open the flow path. On the other hand, when it is desired to change the jet pressure of the bubble flow from the foot side bubble flow spouting section 21 and the back side bubble flow spouting section 22 at desired locations, the subdivision passage 4',
4′, 4′, 4′ of the flow path restricting device C attached to 4′,
The flow passage is narrowed by rotating the valve body of the corresponding flow passage throttling device (motor valve c) C by a predetermined selected angle by touching the throttling degree selection switch. Subdivisions 4', 4', 4' with narrowed flow channels,
The circulating flow flowing through 4' increases the flow velocity and is further throttled by the constriction part (not shown) of the bubble flow jetting part, so the amount of bubbles that are sucked naturally increases in proportion to the flow velocity, and a large amount of bubbles are mixed in. This results in a bubble flow with high ejection pressure.

On the other hand, when the flow channel is not throttled by the flow channel throttle device C, the flow rate of the circulating flow flowing through the desired subdivision channel 4' is slow, even if it is throttled by the throttle section (not shown) of the bubble flow jetting section. The amount of suctioned bubbles is small, resulting in a bubble flow in which a small amount of bubbles are mixed and the ejection pressure is low.

Furthermore, by opening and closing the circulating flow to the foot side passage 4 and the dorsal side passage 4 with the on-off valve B, it is also possible to eject the air bubble flow to the foot side or the back side.

Therefore, the bubble bath device of this embodiment is different from, for example, a system in which a bubble flow is mixed into a circulation flow, and only requires adjustment of the throttling rate of the flow channel throttling device C, that is, the opening degree of the circulation flow channel (channel for circulation flow). The amount of mixed air can be freely adjusted, and a variety of strengths and weaknesses of pine surge waves can be selected reliably and accurately, making it effective for everyone from the elderly to children. In addition, it is possible to freely select the strength or weakness of each bubble flow jetting section 21, 22, such as on the foot side or dorsal side, on both sides (foot side and dorsal side), or partially on the foot side or dorsal side. For example, applying pine surge to areas with muscle pain more strongly than other pine surge areas, preventing injured areas from being exposed to pine surge waves, and adjusting the method to each bather's unique usage and body condition on the spot. You can also do it.
