Description

  The present invention relates to a local cleaning apparatus, and more particularly to a technique for performing local cleaning with a mist.

  In recent years, it has become popular to install a local cleaning device equipped with a cleaning nozzle for spraying hot water as a shower water stream on a local part (to-be-cleaned part) of a human body after a stool to an existing Western-style toilet ( For example, see Patent Document 1).

By the way, since the washing nozzle shown by patent documents 1 has a distance between a washing nozzle and a buttock in the state where a user sat down on the toilet seat, a strong shower water flow is jetted from a washing nozzle toward a buttock. For example, it may feel painful for a person such as a niece. It can also be weakened by adjusting the water temperature of the hot water to be jetted. Even if we wanted to use the shower water flow from the nozzle, there was a problem that it could not be used due to pain.
JP 2000-213039 A

  The present invention has been invented in view of the above-mentioned conventional problems, such as a mist that feels pain in a normal shower water flow by spraying mist toward the local part of the human body and washing with mist. It is an object of the present invention to provide a local cleaning device that allows a person to experience comfortable and gentle mist cleaning and obtains an excellent cleaning effect.

  In order to solve the above-mentioned problems, the present invention is characterized by including a mist spray nozzle 1 for spraying mist M toward a local part of a human body and performing local cleaning with the mist M.

  According to such a configuration, instead of performing local cleaning with a normal shower water flow, water is gradually given to the local area with the mist M, and the mist is floated and removed while the local mucous membrane is sufficiently wetted. Since the system is adopted, even a person with a beard who feels pain in a normal shower water flow can experience a comfortable and gentle mist cleaning.

  The mist M here is generally a particle having a particle size larger than a mist formed by condensation of water vapor in the air into fine water droplets and a particle size smaller than a shower water flow ejected from a normal cleaning nozzle. Therefore, in this mist cleaning method, the local dry mucous membrane is softer than the normal shower water flow, and even if the spray force of mist M is increased, the dirt can be surely felt without causing irritation or damage. Can be washed off.

  In addition to the mist spray nozzle 1, a normal cleaning nozzle 2 for spraying a normal shower water flow is provided, and water from the water supply channel 3 is supplied to the mist spray nozzle 1 side, or a normal cleaning nozzle is provided. It is preferable to provide a flow path switching means 4 for switching whether to supply to the second side. In this case, a person using a mist uses the mist spraying nozzle 1, while a person who is not a person uses a normal washing nozzle 2. Since it can be used, it will be able to handle many users.

  In addition, after the mist mode in which the local cleaning is performed only with the mist M from the mist spraying nozzle 1 is performed for a predetermined time, the mode is automatically switched to the normal cleaning mode in which the local cleaning is performed with the shower water flow from the normal cleaning nozzle 2. The mode switching means 5 is preferably provided. In this case, instead of suddenly applying the shower water flow to the local area from the beginning, the local mucous membrane is sufficiently wetted with the mist M, and in this state, the shower water flow is automatically performed. By switching, a sufficient cleaning effect can be obtained while giving a soft feeling.

  In addition, a hot water temperature control means 6 is provided for setting the hot water temperature supplied to the mist spray nozzle 1 in the mist mode higher than the hot water temperature supplied to the normal cleaning nozzle 2 in the normal cleaning mode. Preferably, in this case, the spraying of the high-temperature mist M further promotes the decomposition and removal of dirt, and the high-temperature mist M has a temperature that can be experienced as compared with the case where a high-temperature shower water stream is jetted from the normal washing nozzle 2. In addition, the temperature of the mist M is likely to decrease due to spray spraying, so that the mist M does not feel too hot, and a clean and comfortable local cleaning with the high temperature mist M can be experienced with peace of mind.

  The local cleaning apparatus according to the present invention sprays the mist from the nozzle for mist spray toward the local part of the human body and performs cleaning with the mist. It is a mist cleaning system that lifts and removes dirt while wetting, and even a person such as a niece who feels pain in a normal shower water stream can experience a comfortable and gentle mist cleaning and obtain an excellent cleaning effect.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 1 shows a state where the mist M is sprayed from the mist spray nozzle 1 protruding into the toilet bowl 7. In FIG. 1, 8 is a local cleaning device provided with a mist spray nozzle 1, 9 is a toilet seat body, and 10 is a toilet lid.

  As shown in FIG. 3, the mist spray nozzle 1 of the present embodiment is fixed to the tip of a nozzle pipe 11 communicating with the water supply path 3 by screwing or the like.

  A conventionally known mist spray nozzle 1 is used. A first known example is shown in FIG. In FIG. 4, an inflow port 1 a communicating with the nozzle pipe 11 is provided upstream in the mist spray nozzle 1, a collision plate 1 b is disposed downstream of the inflow port 1 a, and a plurality of positions on the outer periphery of the collision plate 1 b. A bent hole 1e including a hole 1c extending in the axial direction and a hole 1d extending radially inward from the tip of the hole 1c is formed, and the outlet of each bent hole 1e is downstream of the collision plate 1b. It communicates with the provided discharge chamber 1f. A slit discharge port 1h is provided at the tip of the discharge chamber 1f through an orifice 1g. Here, the inner diameter A of the discharge chamber 1f gradually decreases from the position 1j before the orifice 1g toward the orifice 1g, and the inner diameter B (<A) is minimized at the orifice 1g. The inner diameter C (> B) gradually increases toward the slit discharge port 1h at the tip. As a result, the water supplied from the nozzle pipe 11 to the inflow port 1a collides with the collision plate 1b as shown by the arrow X in FIG. 4, and then is distributed to the plurality of bent holes 1e on the outer peripheral portion. The direction of the discharge chamber 1f is changed, and the inside of the discharge chamber 1f is merged. After that, the orifice portion 1g at the front end side of the discharge chamber 1f is once throttled and then discharged from the slit discharge port 1h at the front end side toward the outside at once. . Thus, the mist M is sprayed from the slit discharge port 1h at a predetermined angle. The spray angle of the mist M is, for example, about 65 °, but is not limited to this value.

  FIG. 5 shows a second known example of the mist spray nozzle 1 ′. The mist spray nozzle 1 ′ shown in FIG. 5 is for spraying the mist M from the slit discharge port 14 through the swirl chamber 13 after the water flowing in from the inlet 1a is swirled by the swivel unit 12. This is known, for example, from Japanese Patent Laid-Open No. 10-28656, and detailed description thereof is omitted.

  Here, the “mist M” in the present invention is generally larger in size than the mist formed by condensation of water vapor in the air and formed into fine water droplets, and more granular than the shower water flow from the normal washing nozzle 2. Compared with the normal shower water flow injected from the normal washing nozzle 2 (FIG. 6), comfort is obtained gently on the skin.

  Thus, at the time of local cleaning, instead of performing local cleaning with a normal shower water flow, as shown in FIG. 2, the mist M from the mist spray nozzle 1 is sprayed on the local N, and moisture is gradually applied to the local. A mist cleaning method is employed in which the mucous membrane of the local N is sufficiently wetted and the dirt is lifted and removed. As a result, even a person with a heel who feels pain in a normal shower water flow can experience a comfortable and gentle mist cleaning. That is, in the method of washing off with a normal shower water flow, it is easy to feel irritation and damage especially when water is applied to the dry mucous membrane of the local N, but in the mist cleaning method of the present invention, the normal mess is against the mucous membrane. Compared with water flow, it is soft, and even if the spray force of mist M is increased, there is an advantage that dirt can be reliably decomposed and washed away without causing irritation or damage.

  FIG. 6 shows an embodiment in which the mist spraying nozzle 1 for spraying the mist M and the normal cleaning nozzle 2 (spout cleaning nozzle 2A, bidet cleaning nozzle 2B) for spraying a normal shower water flow are used together. Show. As the normal cleaning nozzle 2, for example, a conventional technique known from Japanese Patent Application Laid-Open No. 2000-291105 can be adopted, and detailed description thereof is omitted.

  In FIG. 6, a base water supply valve 17, a pump 18, a hot water tank 19, and an opening / closing valve 4 a which is a flow path switching unit 4 are provided on the base portion 16 of the local cleaning device 8 from upstream to downstream of the water supply passage 3. The mist spray nozzle 1, the heel cleaning nozzle 2A, and the bidet cleaning nozzle 2B are connected downstream of the on-off valve 4a. Then, tap water supplied from the outside is supplied to the hot water tank 19 through the water supply valve 17 and the pump 18, heated by the built-in heater 20, and this hot water is supplied to the water supply path 3 and the on-off valve 4a. Accordingly, the mist spray nozzle 1, the heel cleaning nozzle 2A, and the bidet cleaning nozzle 2B are switched to be supplied. Here, as described above, the mist spray nozzle 1 is for atomizing the hot water from the water supply channel 3 and spraying it as a mist M toward the local area. 2A, the bidet washing nozzle 2B) injects hot water from the water supply channel 3 as a normal shower water flow toward the local area.

  Further, a fan 31, a heater 32, and a duct 33 constituting the warm air supply means 30 are installed in the base portion 16.

  An example of the operation unit 15 for operating the local cleaning device 8 is shown in FIGS. The operation unit 15 is provided with a mode selector switch 22 for switching between the normal cleaning standby mode and the mist standby mode, a mist switch 21, an automatic selector switch 5a, a heel cleaning switch 23, a bidet cleaning switch 24, a blower switch 25, and the like. . Further, a normal cleaning standby mode display unit 26 for displaying the normal cleaning standby mode and a mist standby mode display unit 27 for displaying the mist standby mode are provided on both sides of the mode changeover switch 22.

  First, when the mode changeover switch 22 is operated to display the normal washing standby mode display section 26 and then the collar cleaning switch 23 is turned on, the on-off valve 4a shown in FIG. 8 is opened and the pump 18 is turned on. When the normal buttock cleaning mode in which the shower water flow is jetted from the cleaning nozzle 2A and then the buttock cleaning switch 23 is turned off, the on-off valve 4a is closed and the pump 18 is turned off to end the normal heel cleaning mode. In addition, when the bidet cleaning switch 24 is turned on while the normal cleaning standby mode display unit 26 is displayed, the on-off valve 4a is opened and the pump 18 is turned on so that the shower water flow is jetted from the bidet cleaning nozzle 2B. Then, when the bidet washing switch 24 is turned off, the on-off valve 4a is closed and the pump 18 is turned off to complete the bidet washing mode. Further, when the blow switch 25 is turned on, the fan 31 and the heater 32 are turned on and hot air is supplied from the blow port of the duct 33 (FIG. 6), and when the blow switch 25 is turned off, the hot air is stopped. .

  On the other hand, when the mode switch 22 is operated to display the mist standby mode display section 27 and then the mist switch 21 is turned on, the on-off valve 4a is opened and the pump 18 is turned on, and the mist spray nozzle 1 M becomes a mist mode in which spraying is performed. When the mist switch 21 is turned off, the on-off valve 4a is closed, the pump 18 is turned off, and the mist mode ends.

  In addition, the automatic switch 5a is turned on while the mist standby mode display unit 27 is displayed. This automatic changeover switch 5a constitutes a mode changeover means 5 for automatically changing over from the mist mode to the normal washing mode. That is, when the automatic changeover switch 5a is turned on, the mist mode is initially set, and when the predetermined time set by the timer elapses, the mist mode is automatically switched to the normal cleaning mode. Thereafter, when the automatic changeover switch 5a is turned off, the on-off valve 4a is closed, the pump 18 is turned off, and the normal cleaning mode ends.

  Therefore, in this example, the normal cleaning nozzle 2 different from the mist spray nozzle 1 is provided, and the mode changeover switch 22 switches between the mist spray nozzle 1 side and the normal cleaning nozzle 2 side. Can use the nozzle 1 for mist spraying, while the person who is not a bottle can use the normal washing nozzle 2, so that it can sufficiently cope with many users.

  Further, by operating the automatic changeover switch 5a, it is possible to automatically switch to the normal cleaning mode after the mist mode has been performed for a certain period of time, so the shower water flow from the normal cleaning nozzle 2 is suddenly applied to the local area from the beginning. Instead of making the local mucous membrane sufficiently wet with mist M, it becomes possible to apply the shower water flow to the local area. Can be obtained.

  Further, in this example, as shown in FIG. 8, the local cleaning device 8 is provided with a hot water temperature control means 6 for controlling the heater 20 incorporated in the hot water tank 19, and the hot water temperature control means 6 allows the hot water tank 19 to Control hot water temperature. In this example, the hot water temperature supplied to the mist spray nozzle 1 in the mist mode is set higher than the hot water temperature supplied to the normal cleaning nozzle 2 in the normal cleaning mode. First, the temperature of the hot water in the hot water tank 19 at the normal time is set to about 40 ° C., for example, and about 40 ° C. hot water is jetted from the normal cleaning nozzle 2 in the normal cleaning mode. In the case of about 40 ° C., even if a hot shower water flow directly hits the local area, the user will not feel too hot. On the other hand, when the mode is switched to the mist mode, the hot water temperature is raised to, for example, about 50 ° C. At this time, a low temperature mist M of about 40 ° C. is sprayed at first, then the water temperature gradually rises, and finally a high temperature mist M of 50 ° C. is sprayed.

  So, at first, the low temperature mist M reduces the irritation while moistening the local mucous membrane, and then the temperature is increased to a high temperature mist M of 50 ° C. Can be dissolved sufficiently. Further, even when the mist M having a high temperature of 50 ° C. is used as described above, when the mist M is sprayed, the sensible temperature is likely to be lowered, and actually, the temperature is likely to be lowered by spraying the mist M. That is, as compared with a normal shower water flow from the cleaning nozzle 2, even a high temperature mist M of 50 ° C. does not feel too hot, and a clean and comfortable local cleaning with the high temperature mist M can be experienced with peace of mind. Further, by spraying high temperature mist M, the decomposition and removal of dirt is further promoted. Furthermore, although it takes time for the hot water temperature in the hot water tank 19 to rise from about 40 ° C. to about 50 ° C. during normal times, the effect of being able to wash softly over time and dirt are gently washed off. And the effect of further improving local blood promotion.

  In addition, although the said embodiment demonstrated the case where the collar part washing | cleaning nozzle 2A and the bidet washing nozzle 2B were used together other than the mist spraying nozzle 1, only the nozzle 1 for mist spraying may be provided independently, In this case, for example, a liquid medicine for treating hemorrhoids can be supplied as hot water supplied to the mist spray nozzle 1 in addition to tap water. That is, if the drug solution for treating hemorrhoids is sprayed as mist M, not only soft local cleaning is possible, but the drug solution for treating hemorrhoids is automatically applied to the hemorrhoid region, which is extremely effective for the treatment of hemorrhoids.
