【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0020]
Example 1
FIG. 1 is a schematic perspective view of a cleaning toilet seat with a drying function according to the first embodiment of the present invention.
[0021]
In FIG. 1, reference numeral 12 denotes a Western-style toilet bowl, and 13 a cleaning toilet seat body. A toilet seat 14 on which a user sits and adds a toilet seat 15, and a toilet lid 15 that covers the toilet seat when not in use are rotatable. It is installed in. Further, in the cleaning toilet seat body 13, a cleaning water supply means 17 having a cleaning nozzle 16 for cleaning the anus after the toilet is used, an air injection means 19 having a drying nozzle 18, and a control for performing drive control thereof. A part 20 and the like are provided. The washing water supply means 17 is composed of a washing drive unit 21 that moves the washing nozzle 16 into the toilet below the anus, a heater (not shown) that produces hot water, and a functional component (not shown) that ejects the washing nozzle 16. . On the other hand, as shown in FIG. 2, the air injection means 19 is connected to a pressure accumulating container 23 on the discharge side of the air pump 22, and an electromagnetic valve 24 for switching the flow path between open and closed on the downstream side is injected via a connection hose 25. It is connected to a drying nozzle 18 provided with a hole 26. For example, the drying nozzle 18 is also fixedly provided via a drive mechanism unit 27 including a stepping motor (not shown), a gear (not shown), a rack (not shown), and the like that operate and swing back and forth. The The operations such as cleaning, drying, and deodorizing performed by the cleaning toilet seat body 13 and various settings are configured by a user operating a remote controller (hereinafter referred to as a remote controller) 28 provided outside.
[0022]
The operation of the present invention will be described by operating the remote controller 28 with reference to FIG. The remote control 28 has a washing switch 29 for the user to clean the butt after the stool, a bidet switch 30 for women to use mainly after small use, and a drying switch 31 for drying the anus after washing. A stop switch 32, a water adjustment switch 33 for washing, a washing water temperature adjustment switch 34, a front / rear switch 35 for adjusting the positions of the washing and drying nozzles, etc. are provided. A signal is sent to the control unit 20 including the microcomputer on the 13th side, and an operation corresponding to the purpose is performed.
[0023]
First, after the user sits on the toilet seat 14 and adds a use, when the washing switch 29 on the remote control 28 is operated, the washing drive unit 21 is driven and the washing nozzle 16 is moved from the main body 13 to a predetermined position in the toilet bowl 12. The flushed water is sent out under predetermined conditions, and the anus is cleaned. Even if the user operates the drying switch 31 during the cleaning operation, the drive mechanism 27 is not driven and cleaning is continued. The other water flow adjustment switch 33, washing water temperature adjustment switch 34, and front / rear switch 35 operate to change the water flow and temperature of the water and change the position where the washing water is applied. Next, when the user operates the stop switch 32 for instructing to stop cleaning and presses the drying switch 31, the cleaning nozzle 16 is accommodated on the main body 13 side by the cleaning driving unit 21, and the drying nozzle 18 is moved from the driving mechanism unit 27 to the main body 13. At the same time, the air pump 22 is driven to feed air into the pressure accumulating vessel 23 at the same time as a circular arc track that is a substantially curved track. At this time, since the electromagnetic valve 24 is closed, the pressure in the pressure accumulating vessel 23 rises to a closing pressure corresponding to the capability of the air pump 22. Thereafter, the electromagnetic valve 24 is opened and closed at a predetermined cycle, and pressurized air is intermittently injected from the injection hole 26 toward the portion to be cleaned. At that time, the drying nozzle 18 that intermittently injects the pressurized air of the air ejecting means 19 is driven by the drive mechanism unit 27 in a substantially curved orbit, so that the position near the anal part and the surrounding hip surface is the drying nozzle 18. Can move effectively, and can effectively and reliably remove water droplets and water film adhering to the anus and surrounding buttocks surfaces, ensuring that drying is performed and drastically reducing the time required for drying. Can do.
[0024]
Further, the drying nozzle 18 is housed in the main body 13 at the rear of the human body as shown in FIG. 4 in a state where a person is seated, and is configured to enter and exit in a substantially curved path by the drive mechanism 27 as shown in FIG. As a result, it is normally stored in the main body 13 so that there is no obtrusive protrusion in the toilet 12, and the compressed air is supplied from a position close to the anus and the surrounding buttocks surface while allowing it to enter and exit from the back of the buttocks in a substantially curved orbit during dry use. In addition to being able to spray intermittently, the attached water droplets can be effectively blown off and removed and dried in a short time, and the drying nozzle 18 and the like together with the cleaning nozzle 16 and the drive mechanism unit 27 are configured in the main body 13 at the rear of the human body. This makes it easy to assemble the wiring and make it compact.
[0025]
Further, as shown in FIG. 6, the substantially curved trajectory of the drying nozzle 18 is positioned above the trajectory in which the cleaning nozzle 16 operates, so that the drying nozzle 18 and the cleaning nozzle 16 do not collide with each other. Instead, it is possible to prevent such a problem that the water droplets of the cleaning nozzle 16 are blown onto the human body by the sprayed air of the drying nozzle 18. In FIG. 6, the cleaning nozzle 16 is indicated by a two-dot chain line, and the drying nozzle 18 is indicated by a solid line. The advantage when the drying nozzle 18 is operated in a substantially curved orbit will be described with reference to FIG. 6. For example, when the drying nozzle 18 is operated in a linear orbit, the nozzle moves in and out like the cleaning nozzle 16 indicated by a two-dot chain line. As a result, the distance to the human body 3 changes and the distance is increased. In the case of the cleaning nozzle 16, there is no particular problem with the straight path, but in the case of the drying nozzle 18, the distance to the human body 3 is not increased by keeping the distance from the human body 3 by operating in a substantially curved path as shown in FIG. 6. By moving the drying nozzle 18 in a position close to the anus and the surrounding buttocks surface, water droplets and water films adhering to the anus and the surrounding buttocks surface can be effectively and reliably removed. It is possible. This is because the air velocity of the jet air jetted from the jet hole 26 of the drying nozzle 18 decreases as the distance increases, and the energy that blows off water droplets adhering to the human body due to the dispersion of the air flow decreases. . Therefore, by operating the drying nozzle 18 in a substantially curved orbit and moving it while maintaining a distance close to the human body, the energy of the jet air can be effectively utilized for removing the attached water droplets.
[0026]
In addition, since the control unit 20 performs control to operate the air jetting unit 19 after a lapse of a certain time after stopping the ejection of the washing water from the washing nozzle 16, first, large water droplets fall into the toilet bowl 12 and are cleaned. Since the residual water adhering to the portion is reduced, and the pressurized air sent by the air injection means 19 is then injected from the drying nozzle 18, the reduced adhering residual water can be spray-dried, making it more dry The time required can be shortened.
[0027]
In addition, the control unit 20 moves the tip of the drying nozzle 18 from the storage position to a preset injection origin at the start of drying, and performs reciprocal driving a plurality of times while intermittently injecting pressurized air from the injection origin to the injection end point. By performing the above, the drying nozzle 18 simply moves in the buttocks area where no water droplets are attached, and starts spraying from the area where the water droplets are attached. Thereafter, an operation of returning to the initial storage position is performed by reciprocating a plurality of times while intermittently spraying only the water droplet adhesion region. As a result, while intermittently injecting pressurized air, it first blows water droplets from the injection origin, which is one end of the cleaned part, and then returns to the injection origin while blowing remaining water droplets from the multi-end, which is the injection end point. Come on. And a preferable dry state can be implement | achieved by reciprocating on the surface of the collar part almost removed further, intermittently injecting pressurized air.
[0028]
Further, the control unit 20 moves the tip of the drying nozzle 18 to the injection origin at the front of the human body at the start of drying, and then reciprocates a plurality of times between the injection end point at the rear of the human body while intermittently injecting pressurized air. By performing the control, the drying nozzle firstly sprays sequentially from the front of the anus where the amount of water droplets are attached to the back of the human body, so that the washing water droplets of the anus are scattered on the front of the human body. Can be used with peace of mind by those who do not want to.
[0029]
Further, the control unit 20 performs control to vary the position where the pressurized air is intermittently ejected in the forward path and the backward path when the drying nozzle 18 is reciprocally driven, so that the position during the intermittent ejection of the pressurized air is determined. Pressurized air can be applied so as to make up for it, and the film can be dried uniformly without coming off.
[0030]
In addition, since the moving speed of the drying nozzle 18 can be varied, it can be passed through the non-spraying area at a high speed, and the area with a large amount of water droplets can be moved at a low speed. The drying efficiency can be improved over time.
[0031]
