Description

  The present invention relates to a mist ejecting device that is installed in a bathroom, for example, and used by a bather to take a mist shower or the like.

  As an example of a conventional mist ejection device, there is one described in Patent Document 1. The mist ejection device described in the document has a configuration in which a tubular body equipped with a plurality of mist nozzles is accommodated in a casing attached to a side wall of a bathroom. Hot water is supplied into the pipe from a hot water supply hose connected to the lower end of the pipe. According to such a configuration, when hot water is supplied into the pipe, the hot water is misted and ejected from the plurality of mist nozzles into the bathroom. Therefore, the bather can take a mist shower.

  However, the prior art has problems to be improved as described below.

  1stly, it is desirable for the mist ejection apparatus used for a mist shower use etc. to suppress breeding of miscellaneous bacteria and to make it excellent in hygiene. From this point of view, after the mist ejection operation is completed, it is required that a large amount of hot water does not remain for a long time in the hot water flow channel in the pipe body in which the mist nozzle is mounted. . On the other hand, in the prior art, since the hot water supply to the hot water flow channel inside the pipe is performed from the lower end side of the hot water flow channel, the hot water supply to the hot water flow channel is stopped and the mist is ejected. When the process is terminated, it is difficult to quickly discharge the hot water remaining in the hot water flow path to the outside. That is, for example, when a hot water supply hose is connected to the lower part of the hot water channel, even if the hot water supply from the hose to the hot water channel is stopped, a large amount of hot water exists in the hose. In addition, the hot water in the hot water channel cannot flow down into the hose, and it is difficult to quickly discharge the hot water in the hot water channel to the outside.

  Secondly, from the viewpoint of enhancing comfort or flexibility when the user takes a mist shower, it is desired that the amount of mist ejected can be changed as appropriate. On the other hand, in the prior art, it is difficult to do so, and there is room for improvement in this respect. In addition, in Patent Documents 2 and 3, a mist ejection device provided with an additional mist ejection section for ejecting mist toward the bathroom floor separately from the mist ejection section for the mist shower, Although mist jetting devices capable of mist jetting with different lengths have been disclosed, in these devices as well, as in Patent Document 1, it is difficult to appropriately switch the amount of mist jetted, and hot water There is a problem that drainage in the water channel is poor.

JP 2007-159707 A Japanese Examined Patent Publication No. 6-9596 JP 2003-461 A

  The present invention has been conceived under the circumstances as described above, and appropriately prevents a large amount of hot water remaining in the hot water flow path of the apparatus for a long time after the mist ejection operation is completed. It is an object of the present invention to provide a mist ejection device that can be excellent in hygiene and that can appropriately change the amount of mist ejection at the time of mist ejection.

  In order to solve the above problems, the present invention takes the following technical means.

The mist ejection device provided by the present invention includes a first hot water flow channel, a second hot water flow channel provided below the first hot water flow channel, and the first and second hot water flow. A first and a second mist outlet provided in communication with each of the passages and capable of misting and ejecting the hot water supplied to the first and second hot water flow paths. A mist spraying apparatus, a hot and cold water supply section that enables external hot water supply to the first hot water flow path, a lower portion of the first hot water flow path, and an upper portion of the second hot water flow path It provided so as to connect the door, and said first hot water is the second on-off switching mist amount changing valve capable of operation flowing into the hot water flow path of the hot water channel, for the amount of mist change and control means for controlling the valve, and further wherein the hot water supply unit, wherein An original valve having one end connected to the upper part of the hot water flow path or an intermediate portion in the vertical direction, and hot water connected to the other end of the original valve and for supplying the original valve with hot water from the outside The hot water supply pipe is configured to raise the hot water supplied from the outside to the lower part of the hot water supply pipe to a position higher than the original valve, and then turn downward. The mist amount is provided when the control means closes the original valve and turns off the hot water supply to the first hot water flow path from the outside. When the change valve is in the closed state, the valve is switched to the open state, and when the mist amount changing valve is in the open state, the open state is maintained . Hot water to hot water flow path After the supply is stopped, the hot water remaining in the first hot water flow channel flows into the second hot water flow channel and is discharged from the second mist outlet to the outside. It is characterized by that.

  According to such a configuration, the following effects can be obtained.

  First, when the supply of hot water to the first hot water flow channel is stopped and the mist ejection ends, the mist amount changing valve is opened, and the hot water remaining in the first hot water flow channel is the first hot water flow. It flows into the 2nd hot water flow path located under a path. Then, this hot water is discharged to the outside from the second mist outlet. Of course, if hot water originally existed in the second hot water channel, this hot water is also discharged to the outside from the second mist outlet. As described above, in the present invention, unlike the prior art in which hot water is supplied from the lower end side of the hot water flow path, the hot water remaining in the hot water flow path is actively directed downward after the mist ejection ends. Then, the second mist outlet is used to discharge to the outside so that a large amount of hot water does not remain in the hot water channel for a long time. As a result, it is possible to suppress the propagation of germs and the like in the hot water channel and to improve hygiene.

Further, in the present invention, when hot water is supplied from the outside to the first hot water channel,
When the mist amount changing valve is closed, the mist is ejected only from the first mist outlet, while when the mist amount changing valve is opened, the mist amount changing valve is opened from both the first and second mist outlets. Mist eruption is made. Therefore, it is possible to appropriately switch between a case where the amount of mist is large and a case where the amount of mist is small according to the user's request, which can be made comfortable for the user. Furthermore, in the present invention, when the opening / closing operation of the mist amount changing valve is repeated, the mist ejection is intermittently performed from the second mist ejection port, and a massage effect is given to the body of the bather. It is also possible to use in such a manner.
Furthermore, the hot water supply from the hot water supply pipe to the first hot water flow path can be switched on and off accurately using the original valve, and the hot water supply to the first hot water flow path is stopped. In addition, the operation of setting the mist amount changing valve to the open state in relation to the original valve can be performed accurately. In addition, when connecting a hose for supplying hot water from the outside to the hot water supply pipe, this hose should be connected to the lower part of the hot water supply pipe, and when connecting the hose to a high position of the device In contrast, the hose can be easily connected, and the appearance can be improved. Further, if the hot water supplied from the hot water supply pipe to the original valve is once raised to a position higher than the original bubble and then U-turned downward, the original valve is connected to the hot water supply pipe. It can be connected to a so-called vertical position (the same position as installing the original valve in the middle of the pipe extending in the vertical height direction), and it is possible to improve drainage when the original valve is closed Become.

  In a preferred embodiment of the present invention, as the mist amount changing valve, an on-off valve that performs a valve opening operation using water pressure is used, and the control means closes the original valve, When the mist amount changing valve is opened, the mist amount changing valve is opened before the original valve is closed.

  According to such a configuration, before the original valve is closed and the water pressure in the first hot water flow path is lowered, the mist amount changing valve can be appropriately set to the open state using the water pressure. . In addition, if the mist amount changing valve is of a type that uses water pressure to open the valve, it is possible to save power compared to a valve that performs all valve opening and closing operations, for example, by electromagnetic force. Thus, when batteries or the like are used as the power supply for operating the valve, it is suitable for extending the life.

  In a preferred embodiment of the present invention, a first tubular body portion extending in the vertical direction and having the original valve and the mist amount changing valve connected to both upper and lower ends, respectively, and the first tubular body portion A second tube portion connected to an upper portion of the lower part of the mist amount changing valve and rising upward from the connection portion, and the first and second tube portions. Is the first hot water flow path, and each of the first and second tube sections is provided with a plurality of mist nozzles each having the first mist jet port.

  According to such a configuration, the first and second tubular body portions are arranged in a horizontal direction at intervals, and the first hot water is prevented from increasing the overall length in the vertical direction. It is possible to lengthen the substantial overall length of the water flow path and increase the total number of first mist ejection ports. Therefore, it is suitable for increasing the mist ejection amount while reducing the overall size. In addition, the first and second tube sections can have a simple structure in which they are connected to each other at their lower parts, and the first hot water channel having a long dimension can be formed without using a plurality of joints. It can also be formed at low cost. Furthermore, when hot water supply to the first hot water flow path is stopped, hot water can be smoothly flowed into the second hot water flow path from the inside of each of the first and second tubular bodies, and the drainage performance is also improved. It will be good.

  In a preferred embodiment of the present invention, the second mist outlet can eject a coarse mist having a particle size larger than that of the mist ejected from the first mist outlet, and after the mist ejection ends. The opening diameter is made larger than that of the first mist outlet so that the hot water discharge in is promoted.

  According to such a configuration, it is more preferable that the hot water in the first and second hot water flow paths is discharged from the second mist jet outlet at an early stage after the mist jet is finished. When mist ejection is performed, fine mist having a small particle size is ejected from the first mist ejection port, while coarse mist having a larger particle size is ejected from the second mist ejection port. Compared with a case where a mist having a constant particle size is always ejected, a mist shower or the like can be made comfortable for the user.

  In a preferred embodiment of the present invention, the second mist ejection port communicates with the lowermost part of the second hot water flow path or the vicinity thereof so that hot water discharge after the mist ejection ends is promoted. And it opens diagonally downward or downward.

  According to such a configuration, after finishing the mist ejection, hot water is easily discharged from the second mist ejection port, and it is difficult for hot water to remain in the second hot water flow path. can do.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  1 to 5 show an embodiment of a mist ejection device to which the present invention is applied. 1 and 2, the mist ejection device A according to this embodiment includes a mist ejection head H having first and second mist ejection ports 40a and 40b, and the mist ejection head H. A guide rod 60 for slidably supporting in the vertical direction indicated by the arrow N1 is provided.

  In FIG. 1 and FIG. 2, the guide rod 60 is made of, for example, a stainless steel pipe, and a pair of fixtures 61 attached to both upper and lower ends are fixed to the side wall 90 of the bathroom. It is installed in a fashion that extends in the vertical direction on the front side of. As shown in FIG. 2, the mist ejection head H can be moved up and down along the guide rod 60 by inserting a guide rod 60 through holes 18 a of a pair of upper and lower convex portions 18 provided on the back surface thereof. The lower convex portion 18 is provided with a positioning tool 17 provided with an operation portion 17a. By rotating the operation portion 17a, the mist ejection head H can be positioned and fixed and released. The mist ejection head H can be set to a desired height. Further, as shown by an arrow N2 in FIG. 1, the mist ejection head H can be rotated around the guide rod 60 to change its direction.

  As shown in FIGS. 3 and 4, the mist ejection head H includes a hot water supply pipe 2, an original valve V <b> 1, first and second hot water flow paths 3 </ b> A and 3 </ b> B, and a plurality of first water flow paths in a synthetic resin case 1. The first and second mist nozzles 4A and 4B, the mist amount changing valve V2, the control unit 5, and the power supply unit 50 are accommodated. FIG. 4 is a schematic view for facilitating understanding of the internal structure of the mist ejection head H shown in FIG.

  The mist ejection device A is used, for example, in a state where a mixing plug 91 (see FIG. 1) installed in a bathroom and a hot water supply pipe 2 are connected via a hot water supply hose 92. When hot water is supplied to the hot water supply pipe 2, this hot water is supplied to the original valve V1. When the original valve V1 is in the open state, the hot water flows into the first hot water flow path 3A and is misted and ejected from the plurality of first mist outlets 40a. When the mist amount changing valve V2 is in the open state, a part of the hot water in the first hot water channel 3A flows into the second hot water channel 3B, and the mist is discharged from the plurality of second mist outlets 40b. It is configured to be blown out. The front surface of the case 1 of the mist ejection head H is provided with an opening for causing the first and second mist ejection ports 40b to face the outside of the case 1 and appropriately ejecting the mist to the outside of the case 1. It has been.

  The hot water supply pipe 2 has a connection port for a hot water supply hose 92 at its lower end, and temporarily raises the hot water supplied from the hose 92 to a height equal to or higher than that of the original valve V1. It is provided so as to flow into the original valve V1. The combined structure of the hot water supply pipe 2 and the original valve V1 corresponds to an example of the hot water supply section referred to in the present invention.

  The original valve V <b> 1 and the mist amount changing valve V <b> 2 are open / close electromagnetic valves that perform an open / close operation using electric power supplied from the power supply unit 50. However, the valve opening operation uses the water pressure of hot water flowing into the valve. If water pressure is used for the valve opening operation in this manner, energy can be saved, and when a battery or the like is used for the power supply unit 50, the consumption can be suppressed and the service life can be extended. In addition, the type of opening / closing electromagnetic valve that performs valve opening operation using water pressure is known, and detailed description thereof is omitted.

  The first hot water flow path 3A is configured by using the first and second tube portions 31, 32, and the inside thereof is the first hot water flow path 3A, which is substantially U-shaped. is there. The first tubular portion 31 extends in the vertical direction, and has a configuration in which the original valve V1 and the mist amount changing valve V2 are connected to both the upper and lower ends. The second tubular body portion 32 is connected to an upper portion of the lower portion of the first tubular body portion 31 with respect to the mist amount changing valve V2, and stands upward from this connected portion. The upper end of the second tubular portion 32 is in a non-opening state so that hot water does not flow out. A plurality of first mist nozzles 4A are attached to the first and second tube portions 31 and 32 at appropriate intervals and are arranged in two rows. The front end opening of these first mist nozzles 4A is a first mist outlet 40a, which faces substantially in the horizontal direction. Of course, the first mist nozzle 4A can be swung so that the mist ejection direction can be changed. The first mist nozzle 4A has the same structure as a second mist nozzle 4B described later, but the second mist nozzle 4B generates a coarse mist having a relatively large particle size, whereas One mist nozzle 4A generates fine mist having a smaller particle diameter.

  The second hot water flow path 3B is configured by connecting the upper portion of the third tubular portion 33 to the lower portion of the mist amount changing valve V2, and the interior of the third tubular portion 33 is the second. This is a hot water flow channel 3B. The third tubular body portion 33 has a substantially horizontally extending posture, and the third tubular body portion 33 is provided with a plurality of second mist nozzles 4B. The tip opening of these second mist nozzles 4B is the second mist ejection port 40b.

  As shown in FIG. 5, the second mist nozzle 4B is attached to the third tubular portion 33 so as to communicate with the lowermost part of the second hot water flow path 3B or the vicinity thereof. The spout 40b opens obliquely downward. Although it is possible to change the direction of the second mist outlet 40b, it is preferable that the direction can be changed within a range in which the obliquely downward state is maintained. The second mist nozzle 4B generates a swirling flow of the hot water in the intermediate chamber 42 in the second mist nozzle 4B when hot water flows in at a predetermined pressure or more from the inlet 41 formed at the rear end. And it is comprised so that mist-ization of hot water may be aimed at by injecting this from the 2nd mist jet nozzle 40b at high speed. The structure of the second mist nozzle 4B is the same as that of a conventionally known mist nozzle, but mist may be generated based on a different principle. As described above, the second mist nozzle 4B is configured to generate mist having a particle size larger than that of the first mist nozzle 4A, and the opening diameter D1 of the second mist nozzle 40b is The diameter is larger than the opening diameter of the first mist outlet 40a. As described above, increasing the opening diameter D1 and making the second mist outlet 40b obliquely downward means that the hot water existing in the second hot water flow channel 3B is second after the mist ejection operation is finished. It is preferable to quickly flow out from the mist jet port 40b to the outside.

  The control unit 5 is configured using, for example, a microcomputer, and based on a control program stored in advance and an operation command from a separately prepared remote controller R (see FIG. 1), the original valve V1 and the amount of mist It is configured to control the opening / closing operation of the change valve V2. The operation command from the remote controller R to the control unit 5 is performed using conventionally known infrared communication, and the mist ejection head H is provided with a light receiving element (not shown) for infrared communication.

  Next, the operation of the mist ejection device A will be described.

  First, in the state where hot water is supplied to the hot water supply pipe 2 from the mixing tap 91 in the bathroom via the hot water supply hose 92, when the original valve V1 is opened, as described above, the first hot water flow path Hot water flows into 3A, and mist is ejected from the plurality of first mist ejection ports 40a. When the mist amount changing valve V2 is in the closed state, since no hot water is supplied to the second hot water channel 3B, mist is ejected only from the first mist outlet 40a. Since the mist ejected from the first mist ejection port 40a is a fine mist having a small particle size, it is suitable for a user who wants to take a soft feel mist shower. Since the first hot water flow path 3A is formed by connecting the first and second tube portions 31, 32 in a substantially U shape, the plurality of first mist outlets 40a are arranged in two vertical rows. The total number of the first mist ejection ports 40a can be increased while ensuring that the overall dimension in the vertical height direction is bulky by arranging in an orderly manner, and a mist ejection amount that is sufficiently suitable for a mist shower can be secured. Moreover, since the 1st and 2nd tube parts 31 and 32 are the simple structures connected only by one place, unlike the case where they are connected using a some coupling, those assembly costs Can also be cheaper.

  Next, in a state where hot water is supplied to the first hot water channel 3A, when the mist amount changing valve V2 is opened, hot water is also supplied to the second hot water channel 3B, and a plurality of second hot water channels 3A are supplied. Mist ejection is also performed from the mist ejection port 40b. This increases the total amount of mist ejection, which is preferable when the user wants to take more mist. Since the mist ejected from the second mist ejection port 40b has a large particle size, this causes a feel different from that of the mist ejected from the first mist ejection port 40a, which is comfortable to the user. The mist amount changing valve V2 can be repeatedly opened and closed with a relatively short cycle. If it does in this way, from the 2nd mist jet nozzle 40b, mist will be injected intermittently and the effect of massaging a user's body will also be acquired.

  When an operation to end the mist ejection is performed using the remote controller R during the mist ejection, the control unit 5 closes the original valve V1 and stops the hot water supply to the first hot water flow path 3A. At the same time, the mist amount changing valve V2 is opened. When the original valve V1 is closed, if the mist amount changing valve V2 is originally open, the state is maintained. However, if the mist amount changing valve V2 is closed, the mist amount changing valve V2 is maintained. After the valve V2 is opened, the original valve V1 is closed. If the mist amount changing valve V2 is opened before closing the original valve V1 in this way, the mist amount changing valve V2 can be appropriately opened using the water pressure of the first hot water flow passage 3A. it can.

  When the above-described control is performed and the mist ejection is completed, when hot water is present in the second hot water flow path 3B, the hot water is not misted from the second mist outlet 40b. To leak. The hot water in the first hot water channel 3A passes through the mist amount changing valve V2 and flows into the second hot water channel 3B, and then flows out from the second mist outlet 40b. As described above, the second mist jet port 40b has a relatively large opening diameter D1 and is opened obliquely downward, so that hot water tends to flow out to the outside.

  Further, since the first hot water channel 3A is substantially U-shaped, substantially the entire amount of hot water in the first hot water channel 3A smoothly flows into the second hot water channel 3B, and the first hot water channel 3A It is possible to prevent much hot water from remaining in the water flow path 3A. On the other hand, the second mist jet outlet 40b communicates with the lowermost part of the second hot water flow path 3B or in the vicinity thereof, and therefore, substantially the entire amount of the second hot water flow path 3B is transferred to the second mist outlet 40b. It is possible to flow out to the outside, and a large amount of hot water is prevented from remaining in the second hot water channel 3B.

  As described above, in this mist ejection device A, the hot water of the first and second hot water flow paths 3A and 3B is quickly discharged from the second mist ejection port 40b to the outside, and the parts are discharged to these portions. It is possible to prevent a lot of hot water from remaining for a long time. As a result, it is possible to suppress the propagation of miscellaneous fungi in the first and second hot water flow paths 3A and 3B, and to have excellent hygiene.

  6 to 8 show other embodiments of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

  In the embodiment shown in FIG. 6, the bottom surface portion 39 of the second hot water flow passage 3B has a height equal to or higher than the inlet 41 of the second mist nozzle 4B. According to such a configuration, it is more preferable that substantially the entire amount of hot water in the second hot water flow passage 3B is guided to the inlet 41 and discharged from the second mist outlet 40b to the outside.

  In the embodiment shown in FIG. 7, the hot water supply pipe 2 having the original valve V1 in the middle is connected to the middle in the vertical direction of the first hot water flow path 3A. In the present embodiment, the hot water supply pipe 2 is not connected to the uppermost part of the first hot water flow path 3A. However, even in the configuration of the present embodiment, the original valve V1 is closed and the mist ejection operation is performed. When the process is completed, it is possible to cause the entire amount of the first hot water flow path 3A to flow into the second hot water flow path 3B, thereby achieving the object of the present invention.

  In the embodiment shown in FIG. 8, the first and second hot water flow paths 3A and 3B are provided to be inclined at an appropriate angle α with respect to the horizontal direction. Even in such a configuration, after the mist ejection operation is finished, the second mist ejection is performed after flowing the hot water of the first hot water flow channel 3A into the second hot water flow channel 3B using the inclination. It is possible to discharge to the outside from the outlet 40b. The angle α can be set to an arbitrary angle, but the angle α is set to about 5 ° to 10 °, for example, so that the first and second hot water flow paths can be seen in an almost horizontal posture. It can also be set as the structure which carried out. As can be understood from the present embodiment, the first and second hot water flow paths can be inclined. In addition, as shown in FIG. 8, 3 A of 1st hot water flow paths can also be made into a simple linear form. Of course, other forms are possible.

  The present invention is not limited to the embodiment described above. The specific configuration of each part of the mist ejection device according to the present invention can be varied in design in various ways.

  Although it is preferable that the first and second hot water flow paths have shapes in which hot water does not easily remain after the mist ejection operation is finished, the specific shapes thereof are not limited. Moreover, in the said embodiment, although it is comprised so that the roughness of the mist ejected from the 1st and 2nd mist ejection opening may differ, it is also possible to set it as the structure which prepared the roughness of the mist substantially the same. it can. Each of the first and second mist outlets only needs to be provided in at least one, and the specific number thereof is not limited. From the viewpoint of improving the drainage performance of hot water, the second mist outlet is desired to be opened downward or obliquely downward. Instead, for example, the second mist outlet is opened in a substantially horizontal direction. It is also possible to adopt a configuration.

  The mist amount changing valve referred to in the present invention only needs to have a function capable of switching on and off the operation of flowing the hot water in the first hot water channel into the second hot water channel. A different type of valve from the electromagnetic valve that performs the valve opening operation may be used.

  The mist ejection device according to the present invention can be configured as a type used by being mounted on a bathroom floor, for example, as a type used by being mounted on a bathroom side wall, and further a bathroom heating dryer It can also be set as the structure assembled | attached to the bathroom air conditioner, such as.
