Next, the toilet cleaning device 4 will be described with reference to the drawings. 13 is a schematic view schematically showing the toilet bowl cleaning device 4 of the embodiment together with the toilet body 85, FIG. 14 is a cross-sectional view of the self-closing valve and the distribution valve, and FIG. 15 is AA in FIG.
16 is a block diagram showing a schematic configuration of the toilet bowl cleaning device. FIG. 17 shows a schematic diagram of an embodiment relating to abnormality detection of the manual operation part and the toilet bowl cleaning device.

As shown in FIG. 13, in the toilet body 85, rim cleaning for discharging cleaning water from the rim 85a at the upper edge of the ball portion to clean the ball portion 85b and cleaning water from the discharge nozzle 85c at the bottom portion of the ball portion 85b. Is directly discharged to the trap pipe 85d to carry out filth transport and jet cleaning for cleaning the trap portion. The toilet body 85 is provided with the toilet cleaning device 4 for sequentially performing the rim cleaning and the jet cleaning, and the external output port 115a of the toilet cleaning device 4 outputs the rim spout pipe 86 reaching the rim 85a to the outside. From the port 116a, the discharge nozzle 8
The jet water discharge pipes 87 up to 5c are connected and provided. In this case, the distribution and supply of the cleaning water to the rim water discharge pipe 86 and the jet water discharge pipe 87 that guide the cleaning water to the rim 85a and the discharge nozzle 85c are performed by the toilet cleaning device 4 whose configuration will be described in detail below. In this way, the toilet flushing is performed efficiently in both the flush water discharge amount and the instantaneous flow rate.

As shown in FIGS. 13 to 14, the toilet bowl cleaning device 4 has a primary side water supply pipe 103 from a water supply source (water supply).
(The above-mentioned connecting pipe 6) is pipe-connected and has a self-closing valve section 102 having a self-closing function, and a distribution valve section 101 for distributing and supplying washing water in synchronization with the self-closing valve section 102, which are integrated and stacked. The upper end of the valve section 101 is connected to the output port section 104 having the above-mentioned output ports. In this embodiment, the toilet bowl cleaning device 4 has a manual operation section shown in FIG.
By pulling in the direction, the opening operation of the self-closing valve and the operation of the distribution valve start. Thus, the self-closing operation and the distributing operation synchronized with the self-closing operation are performed. The details of this embodiment will be described below.

The self-closing valve section 102 has the following structure so as to perform the self-closing operation by utilizing the differential pressure between the primary side and the secondary side.
The self-closing valve unit 102 includes a primary side water supply passage 103a from the pipe joint 102a to which the primary side water supply pipe 103 is connected to the cleaning device body JV, and a secondary side water passage 111a in the cleaning device body JV. A diaphragm valve 110 and a pilot valve 114 are provided between the water supply passage and the water passage.

The primary side water supply passage 103 is provided with the cleaning device main body JV.
In, the inner wall portion of the main body of the cleaning device is formed so as to surround a water supply valve seat 110a formed by annularly bulging downward. Therefore, the primary-side cleaning water flowing from the primary-side water supply passage 103a applies the primary-side pressure downwardly to the diaphragm valve 110 around the water supply valve seat 110a. In addition, the pipe joint 10 is connected to the primary side water supply passage 103a.
Since the pressure reducing valves 80, 80a (constant flow rate valves or flow regulating valves are also possible) are installed near the inflow port of the cleaning device main body JV downstream of 2a, the water supply valve seat 110 is used during normal cleaning.
A constant pressure (constant flow rate) of cleaning water flows into the surroundings of a. In addition, the pressure reducing valves 80, 80a are
Instead of being incorporated in the pipe, it may be arranged in a pipe upstream of the pipe, a water stopcock, or the like.

The diaphragm valve 110 is a cleaning device body J.
It has a diaphragm 110b which is sandwiched between the cleaning device main body JV and a case 102c constituting a back pressure chamber across the lower end opening of V and which receives the above-mentioned primary side pressure. The diaphragm 110b is vertically and movably sandwiched and incorporated in the back pressure chamber 110c side as described above, and inside the case, it is sandwiched and reinforced by the diaphragm support 112 on the rear surface and the retainer 113 on the upper surface. . The diaphragm support 112 is fixed to the retainer 113 with rivets. Further, the diaphragm 110b is
Due to the pressure balance between the primary side and the secondary side, urging force works,
Normally, the flat portion on the upper surface is used as a valve element and is bonded to the water supply valve seat 110a. As a result, the diaphragm valve 1
10, the primary side water supply passage 103a is always closed by a diaphragm 110b at a water supply valve seat 110a. This state is the closed state (stoppage state) of the diaphragm valve 110, and the toilet bowl cleaning device 4 normally takes this state. The upper and lower guides 110d are the diaphragm support 11
The lower end of the diaphragm 2 is engaged with and integrated with the diaphragm 2 and is vertically movable together with the diaphragm 110b.

The diaphragm valve 110 has the primary side water supply passage 103a and the back pressure chamber 1 even when the diaphragm valve 110 is closed as described above.
Diaphragm 110b to achieve pressure balance with 10c
Has a bleed hole 118 that connects the primary side water supply passage 103a and the back pressure chamber 110c. This bleed hole 118 is
Not only the diaphragm 110b but also the diaphragm support 112 and the retainer 113 are formed so as to penetrate therethrough, and the wash water is always passed from the primary side water supply passage 103a side to the back pressure chamber 110c. In this case, this bleed hole 1
The hole 18 has a small hole diameter, and a cleaning pin 119 described later is also arranged inside the hole 18. Therefore, the primary side water supply passage 1
The washing water of 03a flows into the back pressure chamber 110c little by little through the bleed hole 118. The bleed hole 118, which substantially determines the passage area of the cleaning water in relation to the cleaning pin 119, is a portion where the cleaning pin 119 always exists in the hole, as shown in the enlarged view of the main part of FIG. It is a bleed hole 118 formed in the diaphragm support 12.

The pilot valve 114 causes the opening operation of the diaphragm valve 110 described above. The pilot valve 114 receives directly the upward biasing force of the spring 117 and the periphery of the central through hole of the diaphragm support 112. Pilot valve seat 114a formed by being raised
The pilot valve 114 closes between the secondary side water passage 111a and the back pressure chamber 110c. This state is the pilot valve 11
4 is in the valve closed state (water stop state), and the toilet bowl cleaning device 4 is
This is usually the case.

Here, the transition of the diaphragm valve 110 from the closed state to the closed state through the open state will be described. Pilot valve 114 in closed state
At this point, the pilot valve body 114b is now in the spring 1
When tilted against the biasing force of 17, the pilot valve seat 114a
The adhesive seat of the pilot valve body 114b melts, and the back pressure chamber 110c and the secondary side water passage 111a communicate with each other via the pilot flow passage 111b. In this case, since the back pressure chamber 110c has the same pressure as the primary side water supply passage 103a and a higher pressure than the secondary side water passage 111a, the water in the back pressure chamber 110c passes through the pilot flow passage 111b and the secondary side water passage. It is discharged to the side of 111a. Then, the pressure balance across the diaphragm 110b is lost, and the diaphragm 110b moves downward. Therefore, the diaphragm valve 110b is in an open state in which the water supply valve seat 110a is opened, and the primary side water supply passage 103
The washing water flows into the secondary water passage 111a from a.

On the other hand, when the pilot valve body 114b returns to the upright state, the pilot valve 114b closes the pilot valve seat 114a with the pilot valve body 114b. In this state, the cleaning water flows from the primary side water supply passage 103a into the back pressure chamber 110c through the bleed hole 118 of the diaphragm 110b, and the back pressure chamber 110c is filled with the cleaning water that has flowed in. Then, the pressure of the back pressure chamber 110c becomes equal to the primary side water supply pressure of the primary side water supply passage 103a, and the diaphragm 110b becomes the water supply valve seat 1.
The diaphragm valve 110b is brought into a water-stop state by being bonded to the seat 10a, and water is stopped at the self-closing valve portion 102 (self-closing water stop).

Next, as described above, the self-closing valve portion 102
At the distribution valve unit 101, the valve is opened and the wash water flows in.
Will be described. This distribution valve unit 101 is a self-closing valve unit 1
In order to distribute the supply destination of the washing water in synchronization with the above-mentioned valve opening operation at the time of valve opening by 02, the following configuration is provided.

The distribution valve portion 101 is integrally formed with the self-closing valve portion 102 so as to be located on the downstream side of the self-closing valve mechanism portion 102, and receives the supply of washing water from the diaphragm valve 110b. The distribution valve unit 101 includes a cleaning water distribution chamber 130 that communicates with the secondary side water passage 111a and is formed by partitioning the cleaning device body JV. This wash water distribution chamber 130
Are cylindrical and hollow, and the output ports 11 extending upward are provided on the inner wall surface (the inner wall surface of the distribution chamber) of the column.
5, 116 are formed. This output port 115,
Since 116 is in communication with the external output ports 115a and 116a, the cleaning water flowing into the output port 116 is discharged from the rim 85a through the rim water discharge pipe 86 and used for rim cleaning. The cleaning water flowing into the output port 116 is discharged from the discharge nozzle 85c through the jet water discharge pipe 87 and used for jet cleaning.

The distribution valve section 101 has, inside the wash water distribution chamber 130, a rotary drum 121 which is slidably rotatable while being in contact with the peripheral wall surface of the distribution chamber. The rotary drum 121 is integrally formed with or engaged with a rotary shaft 122 that is rotatably and rotatably supported in the wash water distribution chamber 130, and rotates together with the shaft. At this time, one end of the rotary shaft 122 is pivotally supported by the lateral lid 50a.

The rotating shaft 122 is used for the washing water distribution chamber 13
0 has a cam member 122a inside, and the cam member 122a rotates forward and backward integrally with the rotary shaft 122. As the cam member 122a rotates, the cam member 122a comes into contact with the shaft portion of the pilot valve body 114b and periodically tilts the valve body. The cam member 122a starts the valve opening operation in the self-closing valve portion 102 described above. That is, when the rotary drum 121 and the cam member 122a are in the initial state (water stop state), when the rotary shaft 122 rotates clockwise in the drawing, the cam member 122a tilts the pilot valve body 114b, so the diaphragm valve 11
0b opens as described above.

In the above structure, the drive supply for the self-closing water of the self-closing valve part 102 and the distribution of the washing water of the distribution valve mechanism part 101 is the output gear for the manually operated valve connected to the rotary shaft 122 by the gear train. The manual lever 591 connected to the housing 590 is attached to the case end surface 593a and the shaft end surface
The rotation drive is started by pulling until a is abutted. A mechanical drive source such as a mainspring or a spring is directly or indirectly connected to the rotary shaft 122, and when the rotary shaft 122 is rotationally driven in the closing direction of the self-closing valve 102 by its driving force, distribution is performed. The distribution operation of the valve 101 is performed. In that case, in order to adjust the rotation speed of the rotary shaft 122, a damper 604 (oil damper, air damper, etc.) may be connected via a gear, or speed control may be performed by adjusting with a preload or the like.

In the above structure, a damper mechanism using a damper 604 (oil damper, air damper, etc.) is used to intervene the arm 605 and the spring 607 so that when the manual lever 591 is pulled, the damper mechanism is released. It can be operated with various forces. The arm 6
05, spring 607 may be replaced with a one-way acting damper. At this time, the rotary drum 121
Rotates clockwise with the rotating shaft 122, but the output port 115 remains closed at the beginning of rotation. Therefore, when the diaphragm valve 110b is opened, the cleaning water that has flowed into the cleaning water distribution chamber 130 from the primary water supply path 103a via the secondary side water communication path 111a is output port 11.
6 and is discharged from the discharge nozzle 85c as described above. As a result, jet cleaning is performed.

When the rotary shaft 122 continues to rotate further, since the pilot valve body 114b remains tilted by the cam member 122a, the diaphragm valve 110 maintains the open state, and the cleaning water distribution chamber 130 is continuously supplied with cleaning water. Inflow. During this continuous rotation, the rotary drum 12
Since 1 closes the output port 116 and opens the output port 115, the cleaning water in the cleaning water distribution chamber 130 is output from the output port 1 after the ports are switched in this way.
After passing through 15, the ink is discharged from the rim 85a. Thereby, the rim cleaning is performed. In this way, the rotary drum 1
When the port is switched by 21, the jet cleaning and the rim cleaning are sequentially switched. Moreover, since the diaphragm valve 110 maintains the valve open state due to the inclination of the pilot valve body 114b over this period, the rim cleaning and the jet cleaning are continuously performed without interruption.

On the other hand, when the rotary drum 121 closes the output port 116 and opens the output port 115 and returns to the initial state in which the rotary shaft 122 further rotates in the clockwise direction, the pilot valve body 114b becomes the cam member. Since the diaphragm valve 110 is released from 122a and assumes an upright posture, the diaphragm valve 110 is changed from the valve open state to the valve closed state as described above, and the self-closing valve mechanism section 102 is closed by self-closing water.
By changing the cleaning water distribution chamber 130 and the rotary drum 121, rim-jet-rim pattern cleaning can be performed.

FIG. 17 shows an embodiment relating to the abnormality detection of the toilet bowl cleaning device. When the manual lever 591 which is the manual operation part 4b is pulled, the force is applied to the spring 5 built in the case part 593.
It is transmitted to the valve side output gear 590 via 99 and finally rotates the rotary shaft 122. The spring 599 is set in advance to be equal to or less than the destructive force of the self-closing valve portion and the distribution valve portion. As a result, the distribution valve 101 and the self-closing valve 102
Detects abnormalities such as freezing and dust, and prevents damage to the part in advance.

FIG. 18 shows another embodiment relating to the abnormality detection of the toilet bowl cleaning device. The valve-side output shaft 586 connected to the rotary shaft 122 is provided with the second gear 588, and the spring 589 is provided at the back of the facing first output gear 587 to
The surface pressure is generated in the gear 588 and the first output gear 587. The spring 589 is set in advance to be less than or equal to the destructive force of the self-closing valve portion and the distribution valve portion. By this, abnormalities such as freezing of the distribution valve 101 and the self-closing valve 102, dust and the like are detected, and the destruction of the parts is prevented in advance. If the spring 589 is made of a shape memory alloy, the pressing force to the first output gear 587 is automatically released when the ambient temperature becomes low, so that the distribution valve 101 and the self-closing valve 102 are frozen. It is possible to detect an abnormality such as a bite and prevent damage to the portion in advance.
