DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for reliably and quickly switching washing water in a local washing apparatus.

[0002]

2. Description of the Related Art A local cleaning device is a device installed in a toilet (not shown), and performs cleaning by emitting warm water from below to a local portion of a user. FIG. 13 shows a structural diagram of the local cleaning device. By pressing the installed local cleaning switch (not shown), the water supply valve 50 is opened.
Is released, and when water pressure is applied to the inside of the tank 51, the warm water heated by the heater 52 in the tank 51 flows into the nozzle flow path switching block 57 communicating with the tank 51, and further, the nozzle flow switching block It is fed to either the posterior cylinder 55 or the bidet cylinder 56 via the flow path that has been selectively switched at 57. When the hot water fed into the buttocks cylinder 55 of the buttocks nozzle portion pushes the stored buttocks slider 55a forward, hot water is ejected from the buttocks cap 55b provided at the tip of the buttocks slider 55a toward the local area. Similarly, when hot water is fed into the bidet cylinder 56 of the bidet nozzle portion, the pushed bidet slider 56
Hot water is jetted to a local part from a bidet cap 56b provided at the end of a.

Next, the nozzle flow path switching block 57 will be described with reference to FIG. The flow path communicating with the washing water inlet 58 into which the hot water flows is connected to the bottom washing port 1 connected to the bottom cylinder 55 and the bidet port 2 connected to the bidet cylinder 56 by the rotary valve 10 rotated by the stepping motor 59 disposed below. To
Connected alternatively.

FIG. 15 shows the operation of the conventional rotary valve 10 for performing particularly buttocks washing and bidet washing. With the rotation of the rotary valve 10, the position of the opening 10b provided on the outer peripheral surface also changes.
The posterior washing port 2 and the bidet washing port 3 are provided on both sides of the rotary valve 10 so as to communicate only when 0b is at a predetermined position. Also, rotary valve 1
A lever 10a is protrudingly provided on the outer peripheral surface of the cylinder 0 and opposite to the opening 10b. The lever 10a is locked by the posterior washing port side rib 20a or the bidet washing port side rib 20b. Then, the rotation of the rotary valve 10 temporarily stops at a predetermined position. The posterior washing port side rib 20a and the bidet washing port side rib 20b are disposed below the posterior washing port 2 and the bidet washing port 3, respectively, in the figure, and the lever 10a rotates downward. Has been blocked.

When the lever 10a is located at the posterior washing position A shown in FIG. 15 (b), the opening 1 communicates with the posterior washing port 2, so that hot water flows into the posterior cylinder 55 via the posterior washing port 2. Go on. When the lever 10b is located at the bidet cleaning position B shown in FIG. 15C, the opening 10b communicates with the bidet cleaning port 3,
Hot water flows into the bidet cylinder 56 via the bidet washing port 3.

The switching of the flow path is performed in this manner. When the operation is stopped, as shown in FIG. 15A, the lever 10a is moved to the water stopping position substantially intermediate between the bottom cleaning position A and the bidet cleaning position B. By keeping the opening C, the opening 10b is kept in a water-stop state in which the opening 10b does not communicate with the buttocks washing port 2 or the bidet washing port 3.

However, when the lever 10a is switched from the posterior washing position A or the bidet washing position B to the stop position C, the lever 10a is temporarily locked to, for example, the bidet washing port side rib 20b as shown in FIG. This resets the origin, and then moves to the stop position C. This makes it possible to correct a mechanical shift caused by backlash or the like.

[0008]

In the above-mentioned conventional example, the origin is reset at one place in the nozzle flow path switching block of the local cleaning device having the bottom cleaning mode and the bidet cleaning mode as the cleaning mode. However, other cleaning modes of the local cleaning device include a pre-cleaning mode and a nozzle cleaning mode. In the case of a local cleaning device having many such cleaning modes, a large number of nozzles are required in accordance with each cleaning mode. Therefore, if the origin is reset at only one point as in the conventional example, the operating range of the lever in switching becomes wide, and the switching accuracy becomes unstable. And the position of the opening tends to shift. In addition, the time required for switching becomes long.

The present invention has been made in view of the above points, and has a local cleaning apparatus capable of quickly and accurately switching between cleaning modes even when various cleaning modes are provided. It is an object to provide

[0010]

In order to solve the above-mentioned problems, a local cleaning apparatus according to the present invention has a plurality of local cleaning modes and a pre-cleaning mode, and switches a flow path in accordance with each of the above-mentioned cleaning modes. The nozzle flow path switching block is selectively communicated with the opening at the time of each local cleaning by turning the rotary valve around a rotatable rotary valve provided with a lever portion and an opening on the side peripheral surface. A plurality of local cleaning ports, a pre-cleaning port communicating with the opening during pre-cleaning, and a first reset for performing origin reset by bringing an appropriate one of two resetting parts into contact with the lever portion. And a second reset unit, further comprising a water supply valve for controlling water supply to the nozzle flow path switching block, and a plurality of nozzle units supplied with water through the respective cleaning ports. Have The local cleaning device comprising and. In this way, even when a large number of cleaning ports are arranged around the rotary valve in order to provide many cleaning modes, some home resets performed during operation can be performed by any one of the two reset units. Therefore, it is possible to prevent the rotation range of the rotary valve, that is, the movement range of the lever portion, from becoming too large in one origin reset as compared with the case where the reset portion is provided in one place.

A nozzle cleaning mode is provided, and a nozzle port is provided around the rotary valve so as to communicate with the opening at the time of nozzle cleaning by rotating the rotary valve. The origin is reset by one of the reset units. By doing so, it is possible to clean dirt attached to the nozzle portion, and it is possible to prevent the movement range of the lever portion from becoming too large.

After the user is seated, the opening is communicated with the nozzle cleaning port by turning the rotary valve to wait for local cleaning, and immediately before the local cleaning, the water supply valve is opened to perform pre-nozzle cleaning. Let it do. By doing so, pre-nozzle cleaning is quickly performed simply by opening the water supply valve while keeping the rotary valve in that state.

After the local cleaning is completed, the opening is communicated with the nozzle cleaning port by rotating the rotary valve, and the water supply valve is opened in accordance with the contraction operation of the nozzle to perform the nozzle cleaning. By doing so, the entire nozzle portion can be efficiently cleaned.

After completion of the pre-cleaning, the origin is reset in either the first resetting section or the second resetting section by rotating the rotary valve, and the opening is opened at each local cleaning port during the rotation of the rotary valve. When passing through any of the above, the rotary valve is rotated after opening the opening at the pre-cleaning port for a certain period of time after the completion of the pre-cleaning, or the rotary valve is left in the flow path from the water supply valve to the rotary valve. A pressure sensor is provided, and it is determined whether the opening is to wait at the pre-cleaning port or the rotary valve is rotated according to the output of the residual pressure sensor. This prevents the residual pressure from being applied to the local cleaning port through which the opening passes during the rotation of the rotary valve after the completion of the pre-cleaning.

When the origin is reset in either the first reset section or the second reset section by rotating the rotary valve after the nozzle cleaning, the opening of the rotary valve passes through any of the local cleaning ports. When the nozzle cleaning is completed, the rotary valve is rotated after the opening is kept at the nozzle cleaning port for a certain period of time after the nozzle cleaning is completed, or a residual pressure sensor is disposed in the flow path from the water supply valve to the rotary valve. In accordance with the output of the residual pressure sensor, it is determined whether the opening is to wait at the nozzle cleaning port or the rotary valve is rotated. This prevents the residual pressure from being applied to the local cleaning port through which the opening passes during the rotation of the rotary valve after the nozzle cleaning.

Further, a local cleaning switch for performing the local cleaning and a stop switch for stopping the local cleaning are provided, and when the user is seated and operates the stop switch during the local cleaning, After the local cleaning is terminated halfway, the origin is reset in either the first resetting unit or the second resetting unit by rotating the rotary valve, and further, the local cleaning switch is turned on during the rotation up to the origin resetting. When operated, the above-mentioned reset of the origin is skipped, and the local cleaning corresponding to the operation of the local cleaning switch is performed.
By doing so, it is possible to quickly switch the local cleaning mode interrupt according to the convenience of the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the accompanying drawings. FIG. 1 shows a nozzle channel switching block provided in an example of a local cleaning device according to an embodiment of the present invention. The above example has a configuration similar to that of the conventional example described above, but includes a seating sensor (not shown) for detecting the user's seating, and has a bottom cleaning mode and a bidet cleaning mode as cleaning modes. In addition to the above, a pre-cleaning mode is further provided. The pre-washing mode here is a washing mode in which washing water is sprayed in advance from the pre-washing nozzle shown in FIGS. 4 and 5 to the toilet so that the discharged stool does not easily adhere to the surface of the toilet. is there.

In one example of the nozzle flow path switching block, in addition to the structure of the conventional example, a pre-cleaning port 1 communicating with the opening 10b by the rotation of the rotary valve 10 is further provided around the rotary valve 2. is there. Further, a rib 21 is arranged around the rotary valve 2, and both sides of the rib 21 are a first reset portion 21a and a second reset portion 21b.
By locking the lever 10b, the origin can be reset at two places. In one example, the first reset unit 21a, the bidet cleaning port 3, the pre-cleaning port 1, the posterior cleaning port 2, and the second reset unit 2 are clockwise from the rib 21.
1b.

Briefly describing the actual operation, the lever 10a is placed at the pre-cleaning position D as shown in FIG. In advance, after the seating is detected, the pre-cleaning is performed by opening the water supply valve 50. After that, as shown in FIG. 1B, the lever 10b is brought into contact with the first reset portion 21a to reset the origin, and then waits at the water stop position C. The water stop position C may be any other position as long as the opening 10b does not communicate with any of the ports 1, 2, and 3. When the seating sensor detects the separation, the lever 10a is brought into contact with the second reset portion 21b to reset the origin, as shown in FIG.
10a is located at the pre-cleaning position D.

As described above, according to the position of the lever 10a, the first reset portion 21a and the second reset portion 21
Since the origin is reset by appropriately using b, it is possible to prevent the operating range of the lever from becoming too wide.

FIG. 2 shows a nozzle flow switching block provided in another example of the local cleaning apparatus according to the embodiment of the present invention. The other example has a configuration substantially the same as that of the example, except that a nozzle cleaning mode and a pre-nozzle cleaning mode are further provided as a cleaning mode, and a nozzle cleaning port 4 is further provided around the rotary valve 10. Around the first reset unit 21a, the bidet cleaning port 3, the pre-cleaning port 1, the buttocks cleaning port 2, the nozzle cleaning port 4, and the second reset unit 21b are arranged in this order.

Here, the nozzle cleaning is performed through a nozzle cleaning nozzle portion 57 which is installed above the posterior cylinder 55 and the bidet cylinder 56 and communicates with the nozzle cleaning port 4 as shown in FIGS. This is a cleaning mode for removing dirt attached to the nozzle sliders 55a and 56a. In addition, by performing the nozzle cleaning before the posterior cleaning or bidet cleaning, dirt can hardly be attached to the sliders 55a and 56a of the nozzles. This nozzle cleaning is particularly called pre-nozzle cleaning.

FIG. 2 (a) shows the time of the ass washing operation. When the lever 10a is positioned at the ass washing position A and the water supply valve 50 is opened, the assembling washing port is opened through the opening 10b. 2 can be supplied with water. Also,
In this example, basically, when the origin is reset when the lever 10a moves to the posterior washing position A, the nozzle washing position C, and the bidet washing position B, the first reset unit 21a is set as shown in FIG. When moving to the pre-cleaning position D, the origin is reset using the second reset unit 21a. By selectively using the two reset portions 21a and 21b according to the position of the lever 10a in this manner, the lever 1
0a can be prevented from becoming too wide.

The case of arranging three ports and the case of arranging four ports have been briefly described above. Hereinafter, the operation in actual use will be described in detail based on still another example of the embodiment of the present invention. explain. However, another example is different from the other example only in the arrangement of the cleaning port, and other basic configurations and operation specifications are substantially the same. The operation specification of one example does not include the nozzle cleaning mode and the pre-nozzle cleaning mode as compared with the other examples, and the opening 10a is positioned at the water stop position C at the timing corresponding to the cleaning mode. The operation specifications are the same.

FIG. 6 shows a nozzle flow switching block provided in a further example of a local cleaning device. A first reset portion 21a and a pre-cleaning port are provided around a rotary valve 10 clockwise from a rib 21. 1, a bidet cleaning port 3, a nozzle cleaning port 4, a bottom cleaning port 2, and a second reset unit 21b. That is, the lever 10a
As for the positions of the first reset unit 21a, the bidet cleaning position B, the nozzle cleaning position C, the buttocks cleaning position A, the pre-cleaning position D, and the second reset unit 21 clockwise from the rib 21.
They are arranged in the order of b. In the following description, the position will be described with reference to the position of the lever 10a.

As shown in FIG. 7, before the user is seated, that is, while the seating sensor does not detect seating, the lever 10a
Is positioned at the pre-cleaning position D, and when the seating sensor detects the seating, the water supply valve 50 is opened and the cleaning water is sent to the pre-cleaning nozzle 60 through the pre-cleaning port 1 to perform the pre-cleaning. After the pre-cleaning is completed by closing the water supply valve 50, the rotation of the rotary valve 10 causes the lever 10 to rotate.
a is brought into contact with the first reset portion 21a to reset the origin, and then waits at the nozzle cleaning position C. However, during rotation until the origin is reset, the lever 10a moves the posterior cleaning position A and the bidet. Since it passes through the washing position B, if there is residual pressure in the rotary valve 10 at that time, the residual pressure mainly acts on the buttocks washing port 2.

As shown in FIG. 5, the bottom nozzle portion of the present embodiment has a bottom slider 55a housed in the bottom cylinder 55 by the urging force of the nozzle spring 30 when not in use.
However, since it is a hydraulic expansion and contraction type which is pushed forward by the water pressure against the urging force and fountains from the butt cap 55b, there is a possibility that the buttocks slider 55a may move forward due to malfunction due to residual pressure. Therefore, in this example, the lever 10a is moved after a certain time has elapsed after the water supply valve 50 is closed. The above-mentioned fixed time may be set within a range in which malfunction due to residual pressure does not occur. In addition, a residual pressure sensor (not shown) is arranged in the flow path from the water supply valve 50 to the rotary valve 10 instead of waiting for a fixed time as described above.
The lever 10a may be positioned at the pre-cleaning position D until the movement of the lever 10a is determined according to the output of the residual pressure sensor. The operation in this case is shown in the flowchart of FIG.

As shown in FIG. 9, when the user operates, for example, a poster cleaning switch (not shown) during standby at the nozzle cleaning position C, the water supply valve 50 is opened to open the nozzle cleaning port 4. Nozzle part 57 for nozzle cleaning through
Cleaning water is supplied to the nozzle to perform pre-nozzle cleaning. After that, if the lever 10a is moved to the buttocks washing position A while maintaining the opening of the water supply valve 50, the buttocks washing nozzle portion fed with washing water through the buttocks washing port 2 moves the buttocks slider 55a. After moving forward, a fountain is used to wash the buttocks.

As shown in FIG. 10, when the user operates a stop switch (not shown) during washing of the poster, the water supply valve 50 is closed and the lever 10a is moved to the nozzle washing position C. Then, the water supply valve 50 is opened to perform nozzle cleaning. However, as described above, the buttocks nozzle portion is of a hydraulic expansion and contraction type, and when the water pressure of the washing water loses the urging force of the nozzle spring 30, the buttocks slider 55 a moves the buttocks cylinder 55.
The water feed valve 50 is opened after a certain period of time elapses, for example.
The dirt attached can be washed away by efficiently applying the washing water from a to the buttocks cap 55b.

After the nozzle cleaning is completed by closing the water supply valve 50, the lever 10a is brought into contact with the first reset portion 21a to reset the origin, and thereafter, the lever 10a is returned to the nozzle cleaning position C and the local cleaning is performed again. Enter the standby state. However, since the lever 10a passes through the bidet cleaning position B during the movement up to the origin resetting, if there is residual pressure in the rotary valve 10 at that time, the residual pressure is applied to the bidet cleaning port 3 and the posterior cleaning nozzle section Similarly, there is a possibility that a bidet cleaning nozzle of a hydraulic extension type may malfunction. Therefore,
In this example, the lever 10a is moved after waiting for a certain time to elapse after the water supply valve 50 is closed. The above-mentioned fixed time may be set within a range in which malfunction due to residual pressure does not occur. Instead of waiting for a fixed time, the lever 10a may be positioned at the nozzle cleaning position C until the movement of the lever 10a is determined according to the output of the residual pressure sensor. The operation in this case is shown in the flowchart of FIG.

As shown in FIG. 12, when the local cleaning switch is operated halfway from the nozzle cleaning until the lever 10a is brought into contact with the first reset portion 21a and the origin is reset, the lever 10a moves at that position. Is stopped, the origin reset is skipped, and the nozzle is returned directly to the nozzle cleaning position C. From that position, local cleaning corresponding to the operation of the local cleaning switch is performed. This enables quick interrupt switching of local cleaning.

Further, when the seating sensor detects the user's leaving when the lever 10a is at the nozzle cleaning position C, the origin is reset by the second resetting section 21b and then the pre-cleaning position D is set. With the lever 10a positioned,
After seating, quickly prepare for pre-cleaning. That is, in this example, the second reset unit 21b is used for resetting the origin before moving to the pre-cleaning position D, and the first reset unit 21a is used for resetting the origin before moving to the nozzle cleaning position C. The proper use of the reset portions 21a and 21b prevents the movement amount of the lever 10a from becoming too large.

As described above, the operation at the time of local washing has been described as an example of the posterior washing, but the same operation is performed also for bidet washing.
