Description

  The present invention relates to a toilet bowl cleaning device, and in particular, for discharging and transporting urine and urine and cleaning the toilet bowl, the opening time of the tank outlet is mechanically controlled in two stages for each of the stool and urine. Therefore, the present invention relates to a toilet bowl cleaning device that can always discharge, transport and wash both stool and urine with an appropriate amount of water.

Conventionally, for this type of toilet cleaning device, for example, in Japanese Patent Laid-Open No. 8-311953, basically, a mechanical method is used to drain a large volume of water at an initial stage to allow filth to flow. A toilet cleaning tank device is described which cleans the toilet bowl by flowing a volume of water.
Specifically, in this toilet bowl cleaning tank, when the operation lever is operated to rotate the operation rod, the overflow pipe and the float body connected to the operation rod are pulled up. As a result, the valve body is opened and the water in the internal tank is drained from the toilet. Even if the water level in the internal tank decreases, the water is kept in the water storage chamber of the control cylinder immediately after draining. Thereby, buoyancy is generated in the float body accommodated in the water storage chamber, and the overflow pipe and the valve body pulled up by this buoyancy are lifted and held in the fully open state.

Immediately after draining, when the float body rises to the fully open position, the throttle valve attached to the float body also rises, and the large diameter portion enters the control small hole in the bottom of the water storage chamber. As a result, the flow path area of the control small hole is minimized and the flow path resistance of the control small hole is increased, so that the amount of water flowing out of the control small hole can be minimized. Thereby, the valve member is maintained in the fully open position from immediately after drainage until the water level of the internal tank drops to the vicinity of the bottom surface of the water storage chamber.
When drainage from the drainage port progresses and the water level in the internal tank falls below the level near the bottom of the reservoir, the water in the reservoir will actively flow out of the control hole, resulting in the valve member and The throttle valve descends with the float body. Along with this, the large diameter portion of the throttle valve falls downward from the control small hole, and the flow passage area of the control small hole increases rapidly. From this point, the amount of water discharged from the control cylinder through the control small hole is increased. As the water in the control cylinder suddenly flows out, the float body and the valve member descend rapidly to close the drain port. Immediately after this, water is supplied from the ball tap hydrant, and the inside of the tank is again kept full.

Can

  Therefore, for example, when urine is discharged from a toilet, first the water in the tank is discharged from the outlet to the toilet, and the urine is discharged from the toilet and transported, and then tap water is added to the toilet as additional water for the first time. The toilet can be washed and sealed by draining. Similarly, when stool is discharged from the toilet, first, after the water in the tank is discharged from the outlet to the toilet, the stool is discharged from the toilet and transported, and then the tap water is further discharged for a second time longer than the first time. The toilet can be washed and sealed by draining the toilet as additional water.

  As a result, when the urine or urine is discharged and transported from the toilet and the toilet is washed, the opening time of the tank outlet can be controlled in two stages for each of the stool and urine. It is possible to always discharge, transport and wash the urine with an appropriate amount of water.

  In the toilet bowl cleaning device according to claim 2, the valve opening / closing mechanism has a through cylinder in the center, a water storage tank is formed around the through cylinder, and the upper control hole and the lower are located at two positions on the peripheral wall of the water storage tank. Side control holes are formed, a control tank fixed to the drainage port, and a wide part and a narrow part facing the upper control hole are formed in the water tank, and up and down depending on the water level in the water tank A float body that can float up and down, and an overflow pipe that is movable up and down in the through cylinder and that is provided with a valve body at the lower end corresponding to the valve seat and that is integrated with the float body, And with the overflow pipe pulled upward, the float body is rotated to the first position, the narrow portion of the float body and the upper control hole of the water storage tank are spaced apart from each other, the upper control hole is opened, and the upper control hole and Lower control hole The water in the water storage tank is discharged into the tank for the first time, the valve body and the valve seat are brought into contact with each other, the discharge port is closed, and the float body and the overflow pipe are lifted upward, and the second float body Rotate to the position, the wide part of the float body and the upper control hole of the water storage tank contact each other to close the upper control hole, and the water in the water storage tank is discharged from the lower control hole into the tank for the second time. The valve body and the valve seat are in contact with each other to close the discharge port.

  Thus, in order to control the opening time of the valve body and the valve seat after discharging the water in the tank from the discharge port to the toilet, the float body is rotated to the first position. The water in the water storage tank is discharged from both the upper control hole and the lower control hole into the first time tank by opening the upper control hole by separating the narrow part of the water tank from the upper control hole of the water tank, As the water level in the water storage tank drops, the valve body of the overflow pipe that moves downward in the through cylinder together with the float body contacts the valve seat of the tank to close the discharge port, and drains the water in the tank. For controlling the opening time of the valve body and the valve seat after discharging from the outlet to the toilet to the second time, the wide part of the float body is set to the upper control hole of the water tank while the float body is rotated to the second position. The upper control hole is closed by abutting against Moreover, the water in the water tank is discharged into the second time tank only from the lower control hole, and the valve body of the overflow pipe moves slowly downward in the through cylinder together with the float body as the water level in the water tank decreases. Since the outlet is closed by contacting the valve seat of the tank, the upper control hole of the upper control hole and the lower control hole formed in the control tank is selected more selectively between the narrow part and the wide part of the float body. With a simple mechanical configuration that only controls the amount of water discharged from the water tank by opening and closing the tank, the opening time between the valve body and the valve seat after the water in the tank has been discharged from the outlet to the toilet is reduced. It can be controlled to 1 hour and 2nd time longer than 1st time. Thereby, the amount of additional water can be controlled in two stages.

  Here, in the toilet bowl cleaning device, as described in claim 3, in the state where the float body is rotated to the first position, the tap water is discharged from the drain outlet in accordance with the passage of the first time. This is performed until the float body descends in the water tank due to the decrease in the water in the water tank and the valve body and the valve seat come into close contact with each other to close the drain, and the float body is in the second position. The tap water is discharged from the discharge port in a state where the float body is rotated until the float body descends in the water tank as the water in the water tank decreases as the second time elapses. It is performed until and closes and closes the drain outlet.

  In the toilet bowl cleaning apparatus according to claim 4, by rotating the operation cock in one direction, the float body is pulled upward from the water storage tank via the connecting member and is rotated to the first position in the water storage tank. Further, by rotating the operation cock in the direction opposite to the one direction, the float body is pulled up from the water storage tank via the connecting member and is also rotated to the second position in the water storage tank. The amount of additional water can be switched by a simple operation that simply performs a rotation operation in the direction or the reverse direction.

The link member 33 is movably supported. The water stop member 31 is opposed to a water inlet 34 formed on the upper side of the cylindrical portion 22.

When the water level WL in the tank 4 rises, the float member 26 of the inlet valve 11 configured as described above moves upward together with the sliding support portion 28 due to the buoyancy of the float 27, and the link member 33 moves along the shaft. It rotates counterclockwise around 32. Based on the rotation of the link member 33, the water stop member 31 comes into contact with the water inlet 34 and closes. In contrast, when the water level WL in the tank 4 decreases, the float member 26 moves downward together with the sliding support portion 28 as the water level decreases, and the link member 33 rotates around the shaft 32 in the clockwise direction. Move. Based on the rotation of the link member 33, the water stop member 31 is separated from the water inlet 34 and opened.
In this way, the inlet valve 11 opens the water injection port 34 via the water stop member 31 when the water level in the tank 4 falls below a predetermined level, and supplies water into the tank 4 from the water supply. When the water level becomes equal to or higher than the predetermined water level, the water injection port 34 is closed via the water stop member 31 to block water supply from the water supply to the tank 4.
Note that the inlet valve 11 configured as described above is basically known, and therefore detailed description thereof is omitted here.

  Next, the configuration of the valve opening / closing mechanism 10 will be described with reference to FIG. The valve opening / closing mechanism 10 basically includes the above-described receiving member 18, a control tank 35 fixedly disposed in the receiving member 18, a float body 36 that can float up and down in the control tank 35, and a valve body 37 at the lower end. And an overflow pipe 38 formed integrally with the float body 36.

  Here, in the control tank 35, a through cylinder 39 is formed in the center, and a water storage tank 40 is formed around the through cylinder 39, and at two positions on the upper and lower sides of the peripheral wall of the water storage tank 40, An upper control hole 41 and a lower control hole 42 (see FIG. 6 and the like) are formed. A pair of locking pieces 43 are provided on the peripheral wall of the water storage tank 40. The locking claws 43A formed at the tips of the locking pieces 43 are elastically locked to a pair of locking grooves 44 formed at two locations on the receiving member 18, whereby the control tank 35 is attached to the receiving member 18. Fixed. In addition, a recess 35A is formed on the peripheral wall of the water storage tank 40 on the side opposite to the control holes 41 and 42, and a convex guide portion 35B penetrating the peripheral wall of the recess 35A is provided on the upper side of the recess 35A. It has been. The convex guide portion 35B protrudes to the inside of the peripheral wall (see FIGS. 6 and 7), and the float body 36 rotates when the float body 36 moves up and down in the water storage tank 40 as will be described later. Not to work.

As shown in FIGS. 5 to 7, the float body 36 is formed to be lower than the inner cylindrical portion 45 around the inner cylindrical portion 45 and the inner cylindrical portion 45 opened at the upper and lower portions, and the upper portion is closed. And an outer cylindrical portion 46 whose lower portion is open.
At the upper end of the inner cylindrical portion 45, an upper wall 47 extends horizontally inward, and an insertion hole 48 is formed in the upper wall 47. Arc-shaped concave grooves 49 are formed at two locations on the inner peripheral edge of the insertion hole 48. Each arcuate groove 49 is used when an overflow pipe 38 (described later) is fixed to the float body 36.
A locking portion 50 having an L shape in side view is formed on the side of the peripheral wall of the inner cylindrical portion 45. As shown in FIG. 3, the engaging portion 50 and the operating member 8 fixed to the rotating shaft 7 of the operation cock 6 are connected by a chain 51. Accordingly, the operating member 8 is rotated based on the rotation operation of the operation cock 6, and the locking portion 50 is also rotated according to the rotation of the operating member 8, and the float body 36 will be described later. Thus, it is pulled upward and rotated according to the rotation direction of the operation cock 6.

A concave portion 52 is formed on the outer peripheral surface of the outer cylindrical portion 46, and a pentagonal convex portion 53 formed in a wedge shape upward is formed at a substantially central position of the concave portion 52. The left concave portion 52B that exists between the side surface 53A of the convex portion 53 and the inner side surface 52A of the concave portion 52 is provided with the convex guide portion 35B of the control tank 35 when the urine in the bowl in the toilet body 2 is discharged. The float body 36 is held in the first rotation position, and the right concave portion 52C between the side surface 53A of the convex portion 53 and the inner side surface 52A of the concave portion 52 allows the stool in the bowl in the toilet body 2 to be When discharging, the convex guide portion 35B of the control tank 35 is arranged to hold the float body 36 at the second rotational position. Thus, as will be described later, when the float body 36 is pulled up from the water storage tank 40, the recess 52 cooperates with the convex guide portion 35B provided in the recess 35A of the control tank 35 so that the float body 36 rotates. While acting so as not to move, the float body 36 is held at the first rotation position or the second rotation position.
Further, on the outer peripheral surface of the outer cylindrical portion 46, it can be opposed to the upper control hole 41 formed in the peripheral wall of the water storage tank 40 in the control tank 35 according to the rotational state of the float body 36 at a position separated from the recess 52. A narrow portion 36A and a wide portion 36B are formed (see FIGS. 6A, 6B, 7A, and 7B).

Two arc-shaped guide convex portions 54, 54 are formed on the upper surface of the overflow pipe 38, and the overflow pipe 38 is positioned at a position spaced apart by a minute interval below each guide convex portion 54. A locking projection 55 is formed around the surface. The guide convex portion 54 and the locking projection 55 are used when the overflow pipe 38 is fixed to the inner cylindrical portion 45 of the float body 36. Specifically, the overflow pipe 38 is inserted upward from the lower side of the through cylinder 39 of the control tank 35 and further inserted into the inner cylindrical part 45 of the float body 36. At this time, the overflow pipe 38 is inserted in a state where the respective guide convex portions 54 and the respective arc-shaped concave grooves 49 are brought into contact with each other until the locking convex portion 55 contacts the lower surface of the upper wall 47. Thereafter, the overflow pipe 38 is fixed to the inner cylindrical portion 45 of the float body 36 as shown in FIGS. 6 and 7 by rotating the overflow pipe 38 by a predetermined angle.
A flange portion 56 is formed at the lower end of the overflow pipe 38, and a donut-shaped valve element 37 made of rubber or the like is fixed to the lower surface of the flange portion 56. As will be described later, the valve body 37 contacts and separates from the valve seat 21 based on the fact that the float body 36 moves up and down in the water storage tank 40, and opens and closes the discharge port 20.

Next, the operation of the toilet bowl cleaning apparatus according to the present embodiment configured as described above will be described with reference to FIGS. 3, 6A, 6B, 7A, and 7B.
Here, the toilet bowl cleaning device is in the state shown in FIG. That is, the valve seat 21 on which the receiving member 18 is formed and the valve body 37 fixed to the lower end of the overflow pipe 38 are in contact with each other and close the discharge port 20. Water in the water level WL (full state) is stored in the tank 4, so that the float member 26 of the inlet valve 11 moves upward due to its buoyancy, whereby the link member 33 rotates counterclockwise around the shaft 32. The water stop member 31 closes the water injection port 34 by rotating in the direction. This state is a state where water is stored in the tank 4 after the stool in the bowl of the toilet body 2 is discharged. At this time, the float body 36 is in a state of being rotated to a second rotation position (see FIG. 7) described later.

In the state described above, when the urine in the bowl in the toilet body 2 is discharged, the operation cock 6 is rotated to the back side in FIG. 3, for example. Based on the rotation of the operation cock 6, the actuating member 8 is pulled upward and rotated toward the first rotation position toward the back side.
As a result, the float body 36 is initially moved upward without rotating by the cooperation of the right concave portion 52C and the convex guide portion 35B of the control tank 35. And the convex guide part 35B gets over the vertex of the convex part 53, Then, it arrange | positions in the left side recessed part 52B.

  As described above, when the float body 36 is pulled upward, the valve body 37 at the lower end of the overflow pipe 38 and the valve seat 21 of the receiving member 18 are separated from each other. As a result, the discharge port 20 is opened, so that the water in the tank 4 is discharged from the discharge port 20 to the toilet as shown by arrow A in FIG. 6B, and the urine in the bowl of the toilet body 2 is discharged to the outside. , Transported.

  As described above, when the water in the tank 4 is discharged from the discharge port 20 and the water level WL is lowered, the float member 26 of the inlet valve 11 moves downward as the water level WL is lowered. The water stop member 31 opens the water inlet 34 by rotating clockwise around the shaft 32. As a result, water flows from the water supply into the inlet valve 11 and is supplied into the tank 4 from the water injection port 34. The water supplied into the tank 4 in this way. As a follow-up water is discharged from the open outlet 20 to the toilet, and the bowl of the toilet body 2 is washed. Such additional water is performed until the outlet 20 is closed by the valve seat 21 and the valve body 37.

  Here, even after the water in the tank 4 is discharged from the outlet 20 to the toilet as described above, the water is stored in the water storage tank 40 of the control tank 35, and the float body 36 is shown in FIG. 6B. Thus, the state which floats in the water storage tank 40 with the buoyancy is hold | maintained. In this state, as shown in FIGS. 6A and 6B, the float body 36 has the convex guide portion 35 </ b> B disposed in the left side recess 52 </ b> B, and the narrow portion 36 </ b> A of the float body 36 is separated from the upper control hole 41. And are facing each other.

  Therefore, as shown in FIG. 6B, the water in the water storage tank 40 of the control tank 35 flows from the upper control hole 41 and the lower control hole 42 that are both open for a relatively short time (first It is discharged into the tank 4 in 1 hour). As the water level of the water storage tank 40 decreases based on this, the float body 36 also moves downward, and when the water in the water storage tank 40 runs out, it is fixed to the lower surface of the flange portion 56 of the overflow pipe 38. The valve body 37 and the valve seat 21 of the receiving member 18 come into contact with each other to close the discharge port 20. At this time, the follow-up water through the inlet valve 11 is stopped, and the water supplied from the water supply through the inlet valve 11 is stored in the tank 4. The water supply to the tank 4 is continued at the inlet valve 11 until the float member 26 rises by buoyancy and the water stop member 31 of the link member 33 closes the water injection port 34.

Based on the above contents, the relationship between the water flow rate (L / sec) and time (sec) will be described with reference to FIG.
First, when the operation cock 6 is rotated, the valve seat 21 and the valve element 37 are separated from each other and the discharge port 20 is opened. The water in the tank 4 is discharged at a large flow rate by the siphon principle. 20 is discharged into the bowl of the toilet body 2. As a result, the urine in the bowl is discharged and transported to the outside.

  When the inlet valve 11 is opened based on the drop in the water level of the tank 4, water is supplied from the water supply to the tank 4 through the inlet valve 11 as shown by the dotted line graph in FIG. Water is discharged into the toilet bowl as additional water, and the toilet bowl is washed. As described above, the water in the water storage tank 40 in the control tank 35 is discharged into the tank 4 from both the upper control hole 41 and the lower control hole 42 and the valve body 37 of the overflow pipe 38 is valved. It is performed only for the first time (T1) from when the seat 21 comes into contact with the outlet 20 to close. Thereafter, water is supplied into the tank 4 until the inlet valve 11 is closed.

Next, the operation of the toilet bowl cleaning device when discharging the stool in the bowl in the toilet bowl body, carrying it, and cleaning the toilet bowl will be described with reference to FIGS. 3, 6A, 6B, 7A, and 7B.
Here, the toilet bowl cleaning device is in the state shown in FIG. That is, the valve seat 21 formed on the receiving member 18 and the valve body 37 fixed to the lower end of the overflow pipe 38 are in contact with each other, and the discharge port 20 is closed. Water in the water level WL (full state) is stored in the tank 4, so that the float member 26 of the inlet valve 11 moves upward due to its buoyancy, whereby the link member 33 rotates counterclockwise around the shaft 32. The water stop member 31 closes the water injection port 34 by rotating in the direction. This state is a state where water is stored in the tank 4 after the urine in the bowl of the toilet body 2 is discharged. At this time, the float body 36 is in a state of being rotated to the first rotation position (see FIG. 6).

In the state described above, when the stool in the bowl in the toilet body 2 is discharged, the operation cock 6 is rotated, for example, to the front side in FIG. Based on the rotation of the operation cock 6, the actuating member 8 is pulled upward and rotated toward the second rotation position toward the front side.
As a result, the float body 36 is initially moved upward without rotating by the cooperation of the left concave portion 52B and the convex guide portion 35B of the control tank 35. And the convex guide part 35B is arrange | positioned in 52 C of right side recessed parts, after overcoming the vertex of the convex part 53. FIG.

  As described above, when the float body 36 is pulled upward, the valve body 37 at the lower end of the overflow pipe 38 and the valve seat 21 of the receiving member 18 are separated from each other. As a result, the discharge port 20 is opened, so that the water in the tank 4 is discharged from the discharge port 20 to the toilet as shown by arrow A in FIG. 7B, and the stool in the bowl of the toilet body 2 is discharged to the outside. , Transported.

  As described above, when the water in the tank 4 is discharged from the discharge port 20 and the water level WL is lowered, the float member 26 of the inlet valve 11 moves downward as the water level WL is lowered. The water stop member 31 opens the water inlet 34 by rotating clockwise around the shaft 32. As a result, water flows from the water supply into the inlet valve 11 and is supplied into the tank 4 from the water injection port 34. The water supplied into the tank 4 in this way. As a follow-up water is discharged from the open outlet 20 to the toilet, and the bowl of the toilet body 2 is washed. Such additional water is performed until the outlet 20 is closed by the valve seat 21 and the valve body 37.

  Here, even after the water in the tank 4 is discharged from the outlet 20 to the toilet as described above, the water is stored in the water storage tank 40 of the control tank 35, and the float body 36 is shown in FIG. 7B. Thus, the state which floats in the water storage tank 40 with the buoyancy is hold | maintained. In this state, as shown in FIGS. 7A and 7B, the float body 36 has the convex guide portion 35B disposed in the right-side concave portion 52C, and the wide portion 36B of the float body 36 contacts the upper control hole 41. Facing each other.

  Accordingly, as shown in FIG. 7B, the water in the water storage tank 40 of the control tank 35 is closed by the arrow B only from the opened lower control hole 42 because the upper control hole 41 is closed via the wide portion 36B. As shown in FIG. 2, it is discharged into the tank 4 for a relatively long time (second time). As the water level of the water storage tank 40 decreases based on this, the float body 36 also moves slowly downward, and when the water in the water storage tank 40 runs out, it is fixed to the lower surface of the flange portion 56 of the overflow pipe 38. The valve body 37 and the valve seat 21 of the receiving member 18 come into contact with each other to close the discharge port 20. At this time, the follow-up water through the inlet valve 11 is stopped, and the water supplied from the water supply through the inlet valve 11 is stored in the tank 4. The water supply to the tank 4 is continued at the inlet valve 11 until the float member 26 rises by buoyancy and the water stop member 31 of the link member 33 closes the water injection port 34.

Based on the above contents, the relationship between the water flow rate (L / sec) and time (sec) will be described with reference to FIG.
First, when the operation cock 6 is rotated, the valve seat 21 and the valve element 37 are separated from each other and the discharge port 20 is opened. The water in the tank 4 is discharged at a large flow rate by the siphon principle. 20 is discharged into the bowl of the toilet body 2. As a result, the stool in the bowl is discharged and transported to the outside.

  When the inlet valve 11 is opened based on the drop in the water level of the tank 4, water is supplied from the water supply into the tank 4 through the inlet valve 11 as shown by the solid line graph in FIG. Water is discharged into the toilet bowl as additional water, and the toilet bowl is washed. As described above, the water in the reservoir 40 in the control tank 35 is discharged into the tank 4 only from the lower control hole 42, and the valve element 37 of the overflow pipe 38 comes into contact with the valve seat 21. This is performed for a second time (T2) longer than the first time until the discharge port 20 is closed. Thereafter, water is supplied into the tank 4 until the inlet valve 11 is closed.

  As described above, in the toilet bowl cleaning device according to this embodiment, the valve opening / closing mechanism 10 opens the discharge port 20 at least in two stages of the first time (T1) and the second time (T2) longer than the first time. The time is controlled, the valve body 37 and the valve seat 21 are separated from each other, and the water in the tank 4 is discharged from the discharge port 20 to the toilet. Then, the discharge port 20 is opened based on the control by the valve opening / closing mechanism 10. Since the tap water is supplied to the tank 4 from the water inlet 34 opened by the inlet valve 11 and drained from the outlet 20 to the toilet until one hour or the second time elapses, Water is discharged from the outlet 20 to the toilet, and then drained from the outlet 20 controlled to open by the valve opening / closing mechanism 10 into the toilet as a follow-up water for the first time. Can be drained to the toilet bowl through the discharge port 20 which is release controlled as water chase only tap water longer second time than the first hour.

  Therefore, for example, when urine is discharged from the toilet, first, the water in the tank 4 is discharged from the outlet 20 to the toilet, and the urine is discharged from the toilet and transported. The toilet can be washed and sealed by draining the toilet. Similarly, when the stool is discharged from the toilet, first, the water in the tank 4 is discharged from the outlet 20 to the toilet, and the stool is discharged from the toilet and conveyed, and then the tap water is further discharged for a second time longer than the first time. The toilet can be washed and sealed by draining it into the toilet as additional water for the time.

  From this, it is possible to control the opening time of the outlet 20 of the tank 4 in two stages for each of the stool and urine for discharging and transporting the urine and urine from the toilet and washing the toilet. Both stool and urine can be discharged, transported and washed with an appropriate amount of water at all times.
