Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bubbly water jet tub that jets bath water with air as a bubbly water flow, and more particularly to a bath water jet having a characteristic in the structure inside the tub body.
[0002]
[Prior art]
Conventionally, bath water is sucked in from a suction port device provided on the side wall portion of the bathtub body, externally circulated through a circulation pipe by a circulation pump, and vigorously as a bubble water flow together with air from the injection port device provided on the side wall portion of the bathtub body. Bubble water jet tubs that are jetted into the bathtub body are widely used.
[0003]
Thus, as this bubble water jet tub, there is known a structure in which a suction port device and a spray port device are configured as an integrated suction / spout port device 200 as shown in FIG.
In the figure, 202 is a circulation pump, 204 is a circulation pipe, 206 is a bathtub body, and 208 is a side wall portion thereof.
[0004]
FIG. 7 is an enlarged view of the integrated suction / injection device 200.
In the figure, reference numeral 210 denotes a circular cover member having a large number of openings 212 in the peripheral wall portion.
The bath water inside the bathtub body 206 is sucked into the suction port (not shown) on the inside through these openings 212. The sucked bath water is further externally circulated through the circulation pipe 204 by the circulation pump 202 and is jetted vigorously as a bubble water flow from the nozzle 216 into the bathtub body 206 together with the air sucked from the intake port 214.
[0005]
On the other hand, as shown in FIG. 8, a plurality of air outlets 220 are provided at the bottom 218 of the bathtub body 206, and only air is blown out from the air outlets 222 by the air pump 222 to cause bubbles in the bath water. A bubble tub designed to give birth is also used.
[0006]
[Problems to be solved by the invention]
By the way, when the bubble water jet bathtub shown in FIG. 6 is also provided with a foam jet device as shown in FIG. 8, the following problems may occur.
That is, there arises a problem that the bubbles of the air jetted upward from the bottom portion 218 of the bathtub body 206 are sucked from the suction port device of the bubble water flow ejection device.
If the air inlet device sucks such air bubbles, the circulation pump 202 is temporarily idled. At this time, the safety device is activated and the circulation pump 202 is stopped.
[0007]
Usually, the bubble water flow injection device is provided with a safety device that detects the idling of the circulation pump 202 and thereby urgently stops the circulation pump 202.
This safety device is provided to urgently stop the circulation pump 202 when a towel, a part of a human body, or the like is sucked into the suction port device to avoid danger. If the air is sucked into the circulation pump 202 through the suction port device, it is erroneously determined that an abnormality has occurred, and the circulation pump 202 is stopped.
[0008]
In addition, particularly in the case of a bubble water jet tub in which the suction port device and the spray port device are configured as an integral suction / spout port device 200, bubbles of the bubble water flow jetted from the suction / spout port device 200 are generated. There is a risk that it will bounce off the bather's back and the like, and this will be sucked into the suction / injection device 200 again, causing the pump to stop inadvertently.
[0009]

A circulation pump 20 is provided on the circulation pipe 18.
[0014]
In this example, the bath water inside the bathtub body 10 is sucked in from the suction / injection device 16, and is externally circulated through the circulation pipe 18 by the circulation pump 20 and returned to the suction / injection device 16. It is jetted into the bath water vigorously as a bubbly water flow with air.
As shown in FIG. 1 (B), a pair of suction / injection device 16 is provided on the same side wall portion 12 at a predetermined interval in the left-right direction.
[0015]
The bottom part 14 of the bathtub main body 10 is also provided with a plurality of air outlets 22.
These air outlets 22 are connected to an air pump 26 through an air pipe 24, and air bubbles are ejected from the plurality of air outlets 22 into the bath water by the air pump 26.
As shown in FIG. 1 (B), the blow port 22 at the end closest to the suction / injection device 16 is located in front of the pair of suction / injection device 16 (the inner surface of the side wall 12). Is located).
[0016]
The specific configuration of the suction / injection device 16 is shown in detail in FIG.
In the figure, reference numeral 30 denotes a main body portion. The main body portion 30 includes an outer member 32 disposed on the outer side of the side wall portion 12 and a cylindrical member 34 inserted into the mounting hole 33 from the inner side of the bathtub main body 10. Yes.
[0017]
A male screw is formed on the outer peripheral surface of the cylindrical member 34, and the female screw of the outer member 32 is screwed to the male screw, and the side wall portion 12 is tightened from both the inner and outer sides via packings at the flanges 36 and 38. It is being fixed to the side wall part 12 by.
[0018]
In addition, a nozzle holder 42 having a small-diameter cylindrical portion 40 is fitted into the cylindrical member 34 inside the side wall portion 12, and the front nozzle (bubble water jet nozzle) 43 is vertically moved in the spherical socket portion 44 of the nozzle holder 42. It is held so that it can rotate at a fixed angle from side to side.
[0019]
The cylindrical member 34 has an engaged groove (engaged portion) 46 on the outer peripheral surface of the flange 36 formed on the inner side of the side wall portion 12 and an upper portion (upper end portion), and an engaged groove (covered portion) on the lower portion. (Engagement portion) 48 is formed.
The lower engaged grooves 48 are formed at two positions spaced apart in the circumferential direction by a predetermined distance.
The nozzle holder 42 is provided with an outer cylinder portion 50, and a bath water inlet 52 is formed in the outer cylinder portion 50.
[0020]
The bath water inside the bathtub body 10 is sucked from the suction port 52 and flows through the passage 54 and flows out to the external circulation pipe 18 through the pipe connection part 56 on the outflow side.
The outer member 32 is formed with an inflow side pipe connection portion 58, and bath water sent from the circulation pump 20 through the circulation pipe 18 passes through the inflow side pipe connection portion 58 and is a suction / injection device. 16 is allowed to flow in.
[0021]
The bath water that has flowed into the suction / injection device 16 flows through the internal passage 60 and reaches the rear nozzle (water jet nozzle) 62, from which it is jetted to the right in FIG.
At this time, a negative pressure is generated in the vicinity of the rear nozzle 62, air is sucked from the intake port 64 based on the negative pressure, and the water flow injected from the rear nozzle 62 is bubbled into the bathtub main body 10 from the front nozzle 43 together with the bubbles. It is injected vigorously.
Note that the structure of the suction / injection port device 16 is one example, and it is of course possible to adopt another structure.
[0022]
A cover member 66 is attached to the suction / injection port device 16 of this example so as to cover the suction port 52 on the inner surface of the side wall portion 12 of the bathtub body 10.
3 and 4 show the specific configuration of the cover member 66 in detail.
As shown in these drawings, the cover member 66 includes an upper main body portion 68 and a flange portion 70 that extends downward from the main body portion 68.
[0023]
The main body portion 68 has a cylindrical peripheral surface portion 72 and a front surface portion 74, and a center hole 76 for passing the front nozzle 43 is formed at the center of the front surface portion 74.
On the other hand, the collar part 70 has a pair of left and right side parts 78 and a front part 80.
[0024]
In addition, as shown in FIGS. 2, 3 (B), and 5, the pair of left and right side surface portions 78 has an end surface on the side wall portion 12 side of the bathtub body 10 as an inclined surface 84. A gap 86 (see FIGS. 2 and 5) for allowing bath water to pass through is formed between the inner surface of the portion 12 (82 in the figure is a curved surface).
[0025]
The cylindrical peripheral surface portion 72 of the main body portion 68 has a larger diameter than the outer cylinder portion 50 of the nozzle holder 42 as shown in FIG. 2, and an annular gap is formed between them. Yes.
Specifically, an arcuate opening 88 is formed in the peripheral surface portion 72 of the main body portion 68 at a lower position surrounded by the flange portion 70. A mesh 90 is stretched over the opening 88.
The bath water sucked from the gap 86 is sucked into the suction port 52 through the opening 88.
[0026]
On the inner peripheral surface of the peripheral surface portion 72 of the main body portion 68, the upper engaging claw 92 and the lower pair of engagements at positions corresponding to the upper engaged groove 46 and the lower engaged groove 48. A claw 94 is provided inwardly.
In this example, the cover member 66 is attached to the suction / injection port device 16 by engagement between the engaging claws 92 and 94 and the engaged grooves 46 and 48.
[0027]
Here, the upper engaging claws 92 are formed larger than the pair of lower engaging claws 94, and the upper engaged grooves 46 correspond to the lower engaged grooves 48. Thus, the depth and circumferential length of the groove are increased.
That is, the engagement amount (biting amount) of the upper engagement claw 92 with respect to the upper engagement groove 46 is set larger than that of the lower engagement claw 94 with respect to the lower engagement groove 48.
[0028]
In the case of the bubbly water jet tub of this example, it is possible to effectively prevent the bubbles from the blow port 22 of the bottom portion 14 from being sucked into the suction port 52.
This is because the downward flange portion 70 of the cover member 66 prevents the suction of bath water and bubbles from the gap between the lower end portion and the inner surface of the side wall portion 12 and sucks the bath water from the side surface position. .
[0029]
Since the air jetted upward from the bottom 14 of the bathtub body 10 moves up and down in the bath water as it is, if the bath water is sucked from the side surface according to this example, bubbles are sucked into the suction port 52. This can be effectively prevented.
As a result, it is possible to avoid the inconvenience that the circulation pump 20 is erroneously stopped by bubbles sucked from the suction port 52.
[0030]
When the suction port device and the spray port device are integrally configured as the suction / spout port device 16, the bubble water flow ejected from the suction / spout port device 16 hits the back of the bather and rebounds. However, in this example, such inconveniences can be effectively avoided in the present example.
[0031]
Moreover, in this example, since the clearance gap 86 is formed between the collar part 70 and the side wall part 12 inner surface of the bathtub main body 10, the clearance gap 86 can be formed large and bath water can be suck | inhaled from the suction inlet 52 favorably. .
[0032]
In addition, when the cover member 66 is provided with the downward flange 70 as in this example, a part of the body such as a bather's hand or foot is between the flange 70 and the inner surface of the side wall 12 of the bathtub body 10. There is a possibility of getting in.
In this case, in this example, the cover member 66 is attached to the suction / injection port device 16 by the engagement between the engagement claws 92 and 94 and the engaged grooves 46 and 48, and the engagement amount of the lower engagement claw 94 is set. Since the engaging amount of the upper engaging claw 92 is smaller than that of the upper engaging claw 92, the cover member 66 can be easily detached from the suction / injection port device 16 by the lever principle, and a part of the body such as a hand or a foot is supported by the buttocks 70. And being sandwiched between the side wall portion 12 and the side wall portion 12 can be prevented.
[0033]
On the other hand, even if the bather stretches his legs to apply the bubbly water flow and accidentally pushes the heel portion 70 toward the side wall portion 12, the cover member 66 is not easily removed.
Since the engagement amount of the upper engagement claw 92 is larger than the engagement amount of the lower engagement claw 94, the cover member 66 cannot be easily detached from the suction / injection port device 16.
[0034]
As shown by a two-dot chain line in FIG. 4, an elastic packing 96 having a predetermined length in the left-right direction is attached to the back surface of the lower end portion of the flange portion 70, and the elastic packing 96 is in close contact with the inner surface of the side wall portion 12. You may make it let it.
When doing in this way, between the lower end part of the collar part 70 and the side wall part 12 inner surface can be made into a closed state reliably, and it can prevent more reliably that the bubble which raises upwards is sucked from the clearance gap. it can.
[0035]
Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
