Abstract

PURPOSE:To provide an agreeable bathroom space by reducing a vapor jetting noise and a vapor jetting temperature at the time of steam bathing. CONSTITUTION:By providing a first diffusion chamber 26 and a second diffusion chamber 27, an air current generation noise and a propagation noise are reduced efficiently. Also, while suppressing generation of an air current sound by a bent tube line 25 and a slow reduction line, vapor whose flow velocity is high is jetted into a bathroom. Subsequently, by an injector effect generated in this case, air is sucked from the bathroom outside 23 and mixed with vapor, and vapor of a low temperature is supplied into the bathroom. Moreover, the vapor is allowed to pass through an aromatic box 26 and the bathroom 22 is filled with a fragrant smell. In such a way, a quite and agreeable bathroom space in which a scald does not occur can be realized.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam ejecting device installed on the wall of a steam bath.

[0002]

2. Description of the Related Art As a conventional steam jetting device, one having a structure as shown in, for example, Japanese Utility Model Publication No. 2-9902 and Japanese Utility Model Publication No. 2-9903 is known. The configuration will be described below with reference to FIG.

As shown in FIG. 3, the steam jetting device 1 is mounted by pressing a steam inlet 5 into a pipe cylinder 4 mounted on an inner wall surface 3 of a bathroom 2. An expansion chamber 6 having a volume larger than that of the steam inlet 5 is provided on the downstream side of the steam inlet 5, and a narrow passage 8 is formed on the downstream side of the expansion chamber 6 so that the flow passage gradually decreases as it reaches the steam ejection port 7. It is set up. The upper portion of the expanded chamber 6 communicates with an aroma chamber 10 containing an aromatic agent 9. The pipe cylinder 4 is connected to a pipe line 11 to which steam is supplied from a steam generator (not shown).

In the above structure, the steam supplied from the pipe 11 enters the expansion chamber 6 from the steam inlet 5 and expands, and the narrow passage 8
Is rectified by and is ejected from the steam ejection port 7. During this period, the expansion action of the expanded chamber 6 and the rectification action of the narrow passage 8 reduce the steam ejection noise ejected from the vapor ejection port 7.

By the way, as another vapor jetting device, one having a structure as shown in, for example, Japanese Utility Model Laid-Open No. 3-67645 is known. The configuration will be described below with reference to FIG.

As shown in FIG. 4, a fan cover 13 is arranged in front of the steam supply unit 12, and the inside of the fan cover 18 is partitioned by a partition plate 14 into a central chamber 15 and a side chamber 16, and a fan is placed in the central chamber 15. 17 is provided, a blowout opening 18 corresponding to the central chamber 15 is provided on the front surface of the fan cover 13, and air is introduced into the fan cover 13 from the side chamber 16,
A communication portion that connects the side chamber 16 and the central chamber 15 is provided at the rear portion of the partition plate 14, and the rear surface and the lower surface portion of the fan cover 13 are opened to suck the steam from the steam supply portion 12 into the central chamber 15. It is formed by a suction opening 19 and a lower suction opening 20.

In the above structure, the steam supplied from the steam supply unit 12 is sucked into the central chamber 15 of the fan cover 13 from the rear suction opening 19 and the lower suction opening 20 of the fan cover 13 by the action of the fan 17. on the other hand,
Air is sucked into the side chamber 16 by the action of the fan 17, enters the rear portion of the central chamber 15 from the communicating portion, is diffused by the fan 17 while being mixed with steam in the rear portion of the central chamber 15, and is sent out forward. By thus mixing the steam and air, diffusing them with the fan 17 and dispersing them in the bathroom, the hot steam does not directly hit the human body and it is possible to prevent burns to the human body.

[0008]

However, in the above-mentioned conventional structure, the high-speed steam is expanded and rectified inside the steam jetting device 1 to reduce the jetting noise.
There was a problem that noise reduction was not sufficient. Further, in the other conventional configuration, since the steam temperature is reduced by providing the fan 17 and the motor in the bathroom, the steam jetting device becomes very large and becomes an obstacle in the bathroom, and electric wiring is required, which is troublesome. There was a problem that it was costly.

The present invention solves the above-mentioned problems. By providing a steam jetting device which produces a quiet sound when enjoying a steam bath, music such as TV and audio can be enjoyed in the bathroom and the steam jetting temperature can be reduced. The purpose is to prevent burns, protect the floor of the bathroom washing area, and provide a comfortable bathroom space where you can relax with the scent of an aromatic agent.

[0010]

In order to achieve the above object, a steam jetting device of the present invention is provided with a pipeline for guiding steam of a steam generator, a steam inlet connected to an end of the pipeline, and a steam inlet. The air inlet for introducing the air outside the bathroom provided, the curved pipe passage provided immediately after the steam inlet, the first expansion chamber provided at the rear stage of the curved pipe passage, and the first expansion chamber at the rear stage A second expansion chamber whose flow passage cross-sectional area is gradually reduced and a first communication hole that connects the first expansion chamber and the second expansion chamber and has a flow passage area larger than the flow passage cross-sectional area of the curved pipe. A first spout provided at the end of the second expansion chamber, an air flow path for guiding the air introduced from the air introduction port to the first spout, and an aroma chamber for supplying a scent to the bathroom, The second communication hole connects the first expansion chamber and the fragrance chamber, and the second ejection port provided in the fragrance chamber.

[0011]

According to the present invention, the noise generated in the steam generating device is propagated to the steam jetting device through the pipeline. The steam and the propagating noise that have flowed into the steam ejecting device from the inlet are diverted vertically downward by the curved pipe and are ejected into the first expansion chamber. At this time, the propagation noise is reduced by the expansion-type sound deadening effect, but since the flow velocity of the steam is high, a self-flow noise is also generated in the first expansion chamber. Next, the flow passage area of the first communication hole is made larger than that of the curved pipe, and the steam with reduced flow velocity is ejected into the second expansion chamber. The noise in the bathroom is reduced by silencing the airflow sound generated by the expansion type silencing effect. Further, since the flow passage area of the second expansion chamber is gradually reduced, the flow velocity of steam rises while suppressing the generation of air flow noise and vigorously ejects into the bathroom from the first ejection port. At this time, negative pressure is generated in the vicinity of the first ejection port due to the ejector effect, so the air outside the bathroom is sucked through the air introduction port and the air flow path, the steam and air are mixed, and the steam with reduced steam temperature is made uniform. It can quickly fill the bathroom. In addition, since a part of the steam in the first expansion chamber enters the fragrance chamber through the second communication hole and is ejected into the bathroom through the second ejection port, the scent of the aromatic agent is filled in the bathroom. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The same parts as those shown in the conventional example are designated by the same reference numerals in the following description.

As shown in FIGS. 1 and 2, the steam jetting device 1
Is attached to the bathroom inner wall 3 and is connected to the end of the pipeline 11 that guides the steam generated by the steam generator 21 to the bathroom 22. This steam jetting device 1 is provided with a steam inlet 5 connected to a pipeline 11, an air inlet 24 for introducing the air outside the bathroom 23 provided in the pipeline 11 fitted with the steam inlet 5, and immediately after the steam inlet 5. Of the curved pipe 25, a first expansion chamber 26 provided immediately after the curved pipe 25, and a second expansion chamber 27 provided downstream of the first expansion chamber 26 in which the flow passage cross-sectional area is gradually reduced. And a partition plate 28 separating the first expansion chamber 26 and the second expansion chamber 27, and a first communication hole 29 provided in the partition plate 28 and having a flow passage area larger than the flow passage cross-sectional area of the curved pipe passage 25. And a first ejection port 7 provided at the end of the second expansion chamber 27, and air is introduced from the air introduction port 24 to the first ejection port 7 to separate the first expansion chamber 26 and the second expansion chamber 27. A surrounding air passage 30, an aroma chamber 32 provided at an upper portion of the first expansion chamber 26 and communicating with a second communication hole 31, and a detachment provided inside the aroma chamber 32. Noh aroma box 33, and fragrances 9 inserted in the interior of the fragrance box 33 is configured to include a second ejection port 34 provided to the aromatic box 33.

According to the above structure, the steam and noise generated by the steam generator 21 propagate to the steam jetting device 1 through the pipe 11. The steam and the propagating noise flowing from the steam inlet 5 into the steam ejecting device 1 are smoothly ejected into the first expansion chamber 26 provided vertically downward by the curved pipe line 25. At this time, the propagating noise is reduced by the expansion-type sound deadening effect, but on the other hand, the flow velocity of the steam is high, so that the self-flow noise is also generated. Next, by making the flow passage area of the first communication hole 29 larger than the flow passage area of the curved pipe path 25, the flow velocity is reduced, and air flow noise generated from the first communication hole 29 is suppressed. Next, the vapor with the reduced flow velocity is ejected into the second expansion chamber 27 to generate the air flow noise, and the propagation noise and the air flow sound generated in the first expansion chamber 26 are reduced to the second stage expansion-type silencer. Due to the effect, the noise can be reduced and the noise of the bathroom 22 can be efficiently reduced. Further, since the flow passage area of the second expansion chamber 27 is gradually reduced, the flow velocity of steam rises while suppressing the generation of air flow noise, and the steam is vigorously ejected from the first ejection port 7 to the bathroom 22 to make the vapor uniform. It can be filled quickly. At this time, a negative pressure is generated in the vicinity of the first ejection port 7 due to the ejector effect, so that the air passes through the air introduction port 24 and the air flow path 30 and the outside 23
Is sucked in, the steam and air are mixed, and the bathroom 22 can be filled with the steam having the lowered temperature. Further, since the first expansion chamber 26 and the second expansion chamber 27 are surrounded by the air flow passage 30, the surface temperature of each can be kept low.

Therefore, in the bathroom 22, music of TV or audio can be enjoyed while bathing in steam, and there is no fear of being burned by steam due to the low temperature of jetting steam.
Even if the temperature inside the bathroom 22 rises, the outside of the bathroom 23
Since the air having a low temperature is introduced into the air flow path 30, even if the steam jetting device 1 is directly touched, it will not be burned. Moreover, since a fan and a motor are not required, the device becomes small, and the cost can be reduced and the construction can be simplified.

A part of the steam enters the fragrance chamber 32 through the second communication hole 31 to moisten the fragrance 9 in the fragrance box 33, and
Since it spouts to the bathroom 22 through the second spout 34, the scent of the aromatic agent 9 can be filled in the bathroom 22.

Therefore, it is possible to enter the bathroom and enjoy a comfortable steam bath.

[0018]

As described above, in the steam jetting device of the present invention, the flow of steam can be smoothly changed to the vertically downward direction by the curved pipe line, and the generation of airflow noise is suppressed by the gentle contraction passage of the second expansion chamber. By increasing the steam flow rate while taking in the air outside the bathroom due to the ejector effect, the low temperature steam mixed in the bathroom can be quickly and evenly filled in the bathroom, preventing the hot steam from directly touching the human body and preventing burns. It can protect the floor of the bathroom. Moreover, the noise in the bathroom can be efficiently reduced by the two-stage expansion-type silencing effect that reduces the propagation noise by the first expansion chamber and reduces the airflow noise and the propagation noise by the second expansion chamber. Further, by providing an aroma room, the aroma effect can be provided in the bathroom, and the user can comfortably enjoy the television and audio while taking a steam bath, and can provide a small-sized and low-cost steam jetting device.
