Next, an embodiment of a hot water cleaning apparatus provided with a local cleaning means in the toilet seat according to the present invention will be described.

  As shown in FIGS. 1 and 2, a water supply pipe 1 connected to a water pipe is connected to a water pipe direct connection adapter section 2, and water to be washed water is taken into the hot water washing apparatus from here. This water is heated by the heat exchanger 3, pressurized by the water pump 4, passes through the flow path regulating valve 5, and after adjusting the flow rate there, two local parts for anus and bidet, which are local washing means, are used. Water is branched into the cleaning nozzles 6 and 6 and the nozzle cleaning means 7 which is a dirt cleaning means for washing away the dirt of these local cleaning nozzles 6 and 6a.

  As shown in FIGS. 3 and 4, the local cleaning nozzles 6 and 6 are stored in the nozzle storage portion 8 serving as a storage portion when local cleaning is not performed. 9 is configured to advance and retreat from the rear center of the annular toilet seat 10 provided with 9.

  The nozzle storage portion 8 is composed of a guide cylinder 11 that forms upper, lower, left and right side walls and a lid 12 that opens and closes a front opening through which the local cleaning nozzles 6 and 6 enter and exit, and the lid 12 closes to maintain a substantially sealed space. The substantially sealed space has a structure including a gap due to an error in assembly of the guide cylinder 11 and the lid 12 and the like. The guide tube 11 may be an independent member for forming a substantially sealed space. However, in the present embodiment, the local cleaning nozzles 6 and 6 are used for local cleaning, which is a space surrounded by the nozzle storage portion 8 and the toilet seat 10. A guide member is used to move between appropriate cleaning positions.

  The local cleaning nozzles 6 and 6 can be moved between the storage portion and the cleaning position by the force of a drive source (not shown) using water pressure or electricity. 13 is configured. Then, as shown in FIG. 5, the lid 12 opens when the local cleaning nozzle 6 is in the cleaning position, but the upper end is guided so that the lid 12 is closed by its own weight when the local cleaning nozzle 6 is in the nozzle housing 8. The tube 11 is pivotally supported on the upper edge of the tube 11.

  As shown in FIG. 6, the nozzle storage portion 8 is provided with ribs 14 along the circular outer shape of the local cleaning nozzle 6 inside the guide tube 11, and a substantially sealed space is formed by closing the lid 12. Forming. That is, the nozzle accommodating portion 8 accommodates the tip portion of the local cleaning nozzle 6 where the cleaning water ejection hole 6 a is located in the space surrounded by the rib 14, the lid 12 and the guide cylinder 11. In the figure, reference numeral 15 denotes a central partition wall for partitioning the two local washing nozzles 6, 6 for anus and bidet.

  Further, in order to improve the substantially hermeticity of the nozzle housing portion 8, it is possible to provide rubber packing that contacts the local cleaning nozzle 6 at the end of the rib 14 inside the guide tube 11. Further, the lid 12 is not only closed by its own weight, but, as shown in FIG. 7A, a compression spring 17 is provided at the upper part of the center of the rotary shaft 16 provided on the upper edge of the guide cylinder 11, and the lid 12 As shown in FIG. 7 (b), the lid 12 is always closed in such a configuration as to be biased in the closing direction, and is opened by the force of the local cleaning nozzle 6 that advances to the cleaning position from the nozzle storage portion 8 by power during local cleaning. Further, the nozzle 12 can be closed more effectively by having a mechanism in which the lid 12 is opened and closed in conjunction with commands for starting and stopping the cleaning of the local cleaning nozzle 6 by moving the release 19 with the motor 18. Is possible.

  As shown in FIG. 1, the mist generating means 20 supplies the tap water taken into the hot water cleaning device to the water storage unit 20a from the water channel branched from the pipe connected to the local cleaning water, and is atomized by the ultrasonic vibration device 20b. It becomes a mist, and it is made into the structure which flows in naturally from the inflow port 21 opened to the nozzle accommodating part 8, and is filled. The mist generating means 20 may be any of those caused by heat, those generated by a member that rotates at high speed, those caused by a high voltage, those caused by electrostatic atomization, etc. in addition to ultrasonic vibration.

  The inflow port 21 is provided on the wall of the guide cylinder 12 of the nozzle storage unit 8 at a position substantially the same as or higher than the position of the ejection hole 6a of the local cleaning nozzle 6 stored in the nozzle storage unit 8. The mist that has flowed into the nozzle storage portion 8 flows downward, is naturally guided to the vicinity of the ejection hole 6a, and can be efficiently transported without having a special step for transporting the mist. In order to send the mist from the mist generating means 20 to the nozzle housing portion 8, a conveying means such as an electric fan may be used.

  In addition, as shown in FIG. 1, in the case of a hot water washing apparatus having a structure of a drain port 22 for draining a part of water taken into the hot water washing apparatus as surplus water when the flow rate used for local washing may be small. The surplus water can be effectively utilized by branching from the surplus water drainage channel 22a and supplying the water to the mist generating means 20.

  Now, since the mist generating means 20 fills the generated mist into the nozzle storage portion 8 which is a substantially sealed space, the local cleaning nozzles 6 and 6 as well as the inside of the nozzle storage portion 8 can be subjected to mist cleaning. Since the mist has a particle size of about several to 100 μm, it can float in the air, and the local cleaning nozzle 6 is more complicated than the case where the local cleaning nozzle is washed by applying water or hot water. It can reach the back of a simple shape and can be cleaned efficiently.

  In other words, not only the tip of the local cleaning nozzle 6 where the mist is likely to get dirty, but also penetrates through the details of the complicatedly shaped ejection holes 6a, so that the attached dirt is surely floated and can be put into a mist cleaning state that is easy to remove. The mist concentration may be sufficiently increased in the nozzle housing portion 8 to wash away with water adhering to the surface of the local cleaning nozzle 6, or to be washed away with water or warm water. It is possible to reliably wash away dirt by performing an operation such as wiping.

  Further, the medicine adding means 23 is connected to the upper water passage of the mist generating means 20 so that the medicine is mixed with water and accumulated in the water storage part 20a of the mist generating means 20, and the mist generated from the mist generating means 20 is sterilized and deodorized. In this configuration, a chemical having an effect of removing dirt is added, and the inside of the local cleaning nozzle 6 and the nozzle storage portion 8 is subjected to mist cleaning with the mist added with the chemical.

  In general, the filth contains oil, which cannot be removed by conventional scrubbing with water or hot water, and has been a cause of soiling of the local cleaning nozzle 6 due to its accumulation. As described above, the mist to which the drug is added can deliver the drug to every corner of the local cleaning nozzle 6 having a complicated shape, and the cleaning effect can be further enhanced.

  Further, as shown in FIG. 8, the drainage means 11 a is configured by providing a notch for drainage or the like on the bottom surface of the guide tube 12 of the nozzle storage portion 8 (or from the bottom surface to the side surface of the guide tube 12). . Accordingly, the nozzle cleaning means 7 for cleaning the local cleaning nozzle 6 with hot water or water causes the local cleaning nozzle 6 and the nozzle storage portion 8 after cleaning in the local cleaning nozzle 6 and the nozzle storage portion 8 with the mist to which the medicine is added. Can be washed away with hot water or water, and the dirt that is easily removed by the medicine can be quickly washed out from the drainage means 11a into the toilet. In addition, you may make it drain using the clearance gap which arises on the assembly of the guide cylinder 11 and the lid | cover 12. FIG.

The operation unit 24 is configured to send a command to the control means 25 to operate the hot water cleaning device by operating a button, and starts and stops the local cleaning by the local cleaning nozzles 6 and 6 as in the conventional device, and smells in the toilet. Deodorizing and stopping by the deodorizing device 26 for sucking and deodorizing, drying and stopping by the drying means 27 for drying the part to be cleaned after the local cleaning with warm air, and further the local cleaning nozzle 6 and the nozzle storage part 8 by the mist generating means 20 The mist cleaning and stop of the inside, the addition and stop of the medicine to the water by the medicine addition means 23 at the time of mist cleaning, and the washing and stop of the flushing by the nozzle cleaning means 7 in the local cleaning nozzle 6 and the nozzle storage part 8 are instructed thereafter. .

  The control means 25 is composed of a microcomputer and its peripheral circuits. As shown in FIG. 1, the control means 25 includes a water pump 4, a flow path adjusting valve 5, a local cleaning nozzle unit 13, a mist generating means 20, a drug adding means 23, a deodorizing device 26, A flow that is electrically connected to the drying means 27 and the like, and that incorporates a program for executing the operation and action of the hot water cleaning apparatus described below in response to a command from the operation unit 24, and in particular performs the mist cleaning shown in FIG. There is also a built-in program to execute

  In FIG. 1, 28 is a seating detection means provided on the lower side of the toilet seat 10 to detect whether the user is seated and separated and send a signal to the control means 25 to contribute to the control execution of the control means 25. In addition to the toilet seat, it may be provided in the main body 9 of the hot water washing apparatus or in the remote control device of the hot water washing apparatus, and may be a seating detection means that also serves as an entry detection means for the toilet room.

  In the above embodiment, when the user sits on the toilet seat 10, the deodorizing device 26 is operated by the control means 25, and when the user operates the operation unit 24 after the toilet, the following operations and actions are performed. That is, the local cleaning nozzle 6 pushes the lid 12 open to advance to the cleaning position of the toilet seat 10 from the nozzle housing portion 8, and heat exchange is performed from the ejection hole 6 a of the local cleaning nozzle 6 for anus selected by the flow path adjustment valve 5. Washing water of warm water heated instantaneously in the vessel 3 is jetted to wash the local area. After the local cleaning, when a stop command is issued from the operation unit 24, the local cleaning nozzle 6 moves backward from the cleaning position and is stored in the nozzle storage unit 8, and the lid 12 is closed. In addition, when a local drying command is given, the drying means 27 operates, and the portion to be cleaned wet by the local cleaning is dried with warm air, and when a drying stop command is given, the drying stops.

  In particular, cleaning with mist can be performed at an arbitrary timing in accordance with a user's instruction. However, when the local cleaning nozzle 6 is in the cleaning position after the lid 12 is opened from the nozzle housing portion 8, the cleaning of the local cleaning nozzle 6 is performed. Therefore, it is preferable to control so that mist can be generated only when the local cleaning nozzle is stored in the storage unit.

  FIG. 12 shows the control flow. That is, in this embodiment, the mist generating means 20 causes the mist to be generated at step (hereinafter referred to as S) 1 as shown in FIG. When the command is issued, it is confirmed in S2 whether or not the local cleaning nozzle 6 is stored in the nozzle storage unit 8. If it is not stored, mist is not generated and the process returns to S2 and the above check is repeated again.

  On the other hand, if the local cleaning nozzle 6 is housed in the nozzle storage unit 8 in S2, an error and generation instruction is given in S3, the mist generation unit 20 is operated by the control unit 25, and the ultrasonic vibration device 20b is operated from the water storage unit 20a. As a result, mist is generated and flows from the inlet 21 into the nozzle housing 8 with the lid 12 closed, and the mist is filled.

  Then, the tip of the local cleaning nozzle 6 and the details of the ejection hole 6a are covered with the mist and penetrate the attached dirt to float the dirt and make it easy to remove. Of course, if dirt also adheres to the inside of the nozzle housing 8 at this time, the same action as described above occurs and mist cleaning is performed.

  Of course, if the medicine adding means 23 is operated when the mist generating means 20 is operated and the medicine is mixed with water that becomes mist, the mist generated from the mist generating means 20 has the effect of sterilization, deodorization, and dirt removal. In addition, sterilization, deodorization, and dirt removal are added to the above-described mist cleaning.

  Accordingly, in the mist cleaning state in which the dirt in the local cleaning nozzle 6 and the nozzle storage portion 8 is floating and easily removed, and sterilization, deodorization and dirt removal are added to the mist cleaning. When the adjustment valve 5 is adjusted and the cleaning water flows out from the nozzle cleaning means 7, it falls into the local cleaning nozzle 6 and the nozzle storage portion 8, and dirt that has not been removed by conventional nozzle cleaning can be easily washed away and the nozzle storage portion 8. The drainage means 23 can be surely and quickly discharged, and can always be kept clean.

  Further, after the mist cleaning to which the medicine is added, not only can the dirt that is easily removed by the medicine in the local cleaning nozzle 6 and the nozzle housing portion 8 be easily washed away with hot water or water, but also the local cleaning nozzle 6. In addition, the adhered medicine in the nozzle housing portion 8 can be washed away at a time, and the local cleaning nozzle 6 and the nozzle housing portion 8 can be protected from the medicine.

  In the above embodiment, the nozzle housing 8 and the local cleaning nozzle 6 in the mist cleaning state are washed away with the cleaning water from the nozzle cleaning means 7, but the inside of the nozzle housing 8 has a sufficient mist concentration. The dirt may be removed by rinsing with water adhering to the surface of the local cleaning nozzle 6 or by rinsing with water or warm water separately, or the user may remove the local cleaning nozzle 6 from the nozzle housing 8. It is also possible to make sure that the dirt is washed away by performing an operation such as wiping it out.

  In the above-described embodiment, both the local cleaning nozzle 6 and the nozzle storage unit 8 are in the mist cleaning state. However, at least only the local cleaning nozzle 6 that is easily contaminated may be used.

  As described above, in the present embodiment, in the hot water cleaning apparatus having a means for detecting that the user is sitting on the toilet seat 10, the user can stand up from the toilet seat and leave the toilet cleaning nozzle with a mist after a predetermined time has passed. Since it is possible to make a reservation to perform, the local cleaning nozzle 6 is always automatically cleaned after use of the hot water cleaning device, so that it can be kept clean.

(Embodiment 7)
FIG. 15 is a chart of a control flow to mist cleaning in the hot water cleaning apparatus according to the seventh embodiment of the present invention. The present embodiment is a control method for learning the use time of the hot water cleaning device and entering mist cleaning when the hot water cleaning device is not used, and is applicable to each of the first to sixth embodiments. The cleaning apparatus has the same configuration and operation as the hot water cleaning apparatus shown in FIGS. 1 to 9, and the control flow for different mist cleaning will be described with reference to FIGS.

  The control means 25 shown in FIG. 1 has a built-in program for executing a control flow for generating mist shown in FIG. 15, and a learning means 34 for storing the usage time of the hot water cleaning apparatus. The operation unit 24 is provided with a mist generation reservation command button (not shown).

  Next, a method for controlling mist cleaning will be described. When the mist generation reservation instruction is given by the operation unit 24 in S19, it is checked whether the user is seated on the toilet seat 10 in S20, and when the user is seated on the toilet seat 10, the seating start time is learned in the next S21. It memorize | stores in the means 34 and progresses to following S22.

  In step S22, the user sits on the toilet seat 10 to check whether the local cleaning and drying of the portion to be cleaned are finished and the separation from the toilet seat 10 is finished. If not, the user returns and checks again. If the seating is completed, the seating end time, which is the usage time of the hot water cleaning device, is stored in the next S23. Then, the learning means 34 calculates and stores the use time of the hot water washing device in S24 based on the previous seating start time and the seating end time, and returns to S20.

  On the other hand, when the user is not seated on the toilet seat 10 in S20, it is checked whether the use time of the hot water washing device is based on the use time stored in the next S25, and if it is the use time, the process returns to S20. The check is repeated again, and if it is not the use time, it is checked in S26 whether a certain time has elapsed since the previous mist occurrence. When a certain time has not elapsed since the previous mist generation, the process returns to S20 and the check is repeated again. When the certain time has elapsed, the process proceeds to S27 to instruct the mist generation means 20 to generate mist. After S27, mist cleaning is performed as described in the first embodiment.

As described above, in the present embodiment, since there is means for storing the use time of the hot water washing apparatus, the learning means 34 of the control means 25 estimates the time zone that is not used from the storage of the use time, and the time zone. Further, the mist cleaning of the local cleaning nozzle 6 can be automatically performed, and the convenience can be further improved.

  In this case, by storing the previous mist occurrence time and generating the mist only when a certain period of time-for example, 1 day-has elapsed since then, it becomes possible to periodically clean the local cleaning nozzle. It can prevent repeated occurrence.

  In each of the above embodiments, the “mist generation” shown in FIGS. 9 and 12 to 15 is not limited to a method for generating a mist for a predetermined time and cleaning the local cleaning nozzle. After the mist is generated for a predetermined time and the local cleaning nozzle is cleaned, the local cleaning nozzle and its storage section may be washed away with hot water or water.

  Further, the nozzle accommodating portion 8 in each of the above embodiments is provided with a lid 12 that closes the front opening, and is substantially sealed. However, there are a guide cylinder 11, a gap due to an error in the assembly of the lid 12, and a drainage means 11a. Even if mist leaks from the mist, it will not interfere with mist cleaning.

  Further, the nozzle housing portion 8 in each of the above embodiments is provided with a lid 12 and is substantially sealed. However, the nozzle housing portion 8 may be configured without the lid 12, in which case the mist is forced to flow into the nozzle housing portion 8, The operation effect substantially equivalent to that of the present embodiment can be expected by introducing a large amount of water or by concentrating the mist on the local cleaning nozzle.

  Further, the nozzle storage portion 8 in each of the above embodiments is configured by a dedicated member that forms a storage portion such as the guide tube 11 and the lid 12, but after the local cleaning is finished, the nozzle storage portion 8 is retracted from the space of the toilet seat 10 toward the main body 9 side. When the local cleaning nozzle 6 is housed in a space formed by being surrounded by other members constituting the main body 9 as a result, the space portion may be used as a housing portion.

  The hot water cleaning device of the present invention can be used cleanly by raising the dirt sufficiently with regard to the detailed structure of the local cleaning means, so that not only the local cleaning means but also the local cleaning It can also be applied as a cleaning means for the structure of the outlet, such as the cleaning structure of the means, drying, and deodorizing.
