Description

  The present invention relates to a cleaning apparatus.

  Patent Document 1 discloses a cleaning device for a flush toilet that is improved in cleaning effect by siphon action. The cleaning device includes a cleaning tank, a water storage unit, and an air passage. The water storage unit communicates with the cleaning tank at a height lower than the cleaning water storage level of the cleaning tank. The air passage communicates between a position higher than the water storage level of the washing tank in the water storage part and a position higher than the water sealing part in the drainage path of the toilet bowl.

  In this cleaning device, when the cleaning water is supplied to the toilet bowl and the water level in the cleaning tank is lowered, the water level in the water storage unit is also lowered, and accordingly, the air in the drainage channel is sucked into the water storage unit. Due to the action, the momentum of the inflow of washing water from the toilet bowl into the drainage channel is increased, and a high washing effect can be expected.

Japanese Utility Model Publication No. 5-57080

  This type of cleaning device may be combined with a plurality of types of toilet devices having different shapes of toilet bowls and drainage paths. If the shape of the toilet bowl and the drainage path is different, the drainage flow rate of the washing water in the drainage channel may be different even if the supply flow rate to the toilet bowl is constant. The drainage flow rate in the drainage channel affects the suction force for sucking the air in the drainage channel to the reservoir and the cleaning power for discharging the filth in the toilet bowl.

For this reason, when combined with a toilet apparatus in which the drainage flow rate is increased, there is a concern that the suction force from the drainage channel to the water storage portion becomes too strong, and the filth flowing through the drainage channel is sucked into the ventilation channel. In addition, when combined with a toilet device having a reduced drainage flow rate, there is no concern about suction of filth into the air passage, but there is a concern that the cleaning function for discharging filth out of the toilet bowl may be deteriorated.
Thus, in the case of the conventional cleaning device, there is a possibility that the cleaning performance may become unstable depending on the toilet device to be combined.
The present invention has been completed based on the above circumstances, and an object thereof is to stabilize the cleaning performance.

As means for achieving the above object, the invention of claim 1 is directed to a cleaning tank, a water storage part communicating with the cleaning tank at a height lower than a water storage level of the cleaning tank, and the water storage part in the water storage part. An air passage communicating between a position higher than the water storage level of the washing tank and a position higher than the sealing portion in the drainage channel of the toilet bowl, an upstream end connected to the washing tank, and a downstream end connected to the toilet bowl A water supply path connected to the cleaning tank, a cleaning water control means for controlling a supply flow rate of the cleaning water from the cleaning tank to the toilet bowl, and an electromagnetic on-off valve for ventilation provided in the ventilation path, from the drainage path An intake control unit that controls an intake operation to the water storage unit, and the cleaning water control unit includes a pump provided in the water supply channel, and supplies the cleaning water from the cleaning tank to the toilet bowl. In the early stages of supply. The toilet bowl is washed with a small pumping flow rate, and then the pumping flow rate of the pump is increased to increase the suction force from the drainage channel to the water reservoir, and at the end of the supply, It is characterized in that the flow rate is reduced to a small amount.

According to a second aspect of the present invention, in the first aspect of the present invention, the intake control means is configured by dividing the water storage section into an upper water storage chamber and a lower water storage chamber by a partition wall having an orifice. It has the characteristics.

The invention of claim 3 is characterized in that, in the invention according to claim 2 , the lower water storage chamber is provided with a closing member capable of closing the orifice by floating on the cleaning water in the water storage section. Have.

<Invention of Claim 1>
The washing performance can be stabilized by controlling the supply flow rate of the washing water from the washing tank to the toilet bowl according to the shape of the toilet bowl and the drainage channel by the washing water control means. That is, in the case where the drainage flow rate in the drainage channel is increased, if the supply flow rate of the wash water to the toilet bowl is reduced, the intake force from the drainage channel to the water storage section becomes too strong. It is possible to prevent filth from being sucked in. Further, in the case where the drainage flow rate in the drainage channel is reduced, the cleaning function for discharging filth to the outside of the toilet bowl can be improved by increasing the supply flow rate of washing water to the toilet bowl.

Further, since the pump provided in the water supply channel is used as the washing water control means, the supply of washing water from the washing tank to the toilet bowl can be stably controlled even if the height of the washing tank is low.

In addition, by controlling the intake operation from the drainage channel to the water storage unit by the intake control means, it is possible to demonstrate the siphon action at a suitable timing according to the supply state of the wash water from the wash tank to the toilet bowl, A high cleaning effect can be obtained.

<Invention of Claim 2 >
When the supply of the wash water from the wash tank to the toilet bowl is started, the wash water that passes through the orifice in the initial stage of supply is liquid, so that the water level drop in the reservoir is relatively slow. When the water level in the water storage section falls below the partition wall, air having a smaller flow resistance than the wash water passes through the orifice, so that the water level in the water storage section decreases rapidly and siphon action is enhanced. The

<Invention of Claim 3 >
When the supply of the wash water from the wash tank to the toilet bowl is started, the flow rate of the wash water passing through the orifice is reduced compared with the case where there is no occlusion member because the closing member tries to close the orifice in the initial stage of the supply. . Then, after the water level in the water storage unit drops and the closing member starts to descend, air having a smaller flow resistance than the wash water passes through the orifice, so that the water level in the water storage unit decreases rapidly. Compared with the case where no closing member is provided, the present invention can delay the timing at which the siphon action starts to function.

<Embodiment 1>
A first embodiment embodying the present invention will be described below with reference to FIG. FIG. 1 shows a flush toilet bowl configured by combining a toilet apparatus E with a cleaning apparatus A. The toilet device E includes a toilet bowl 40 and a drainage channel 41 communicating with the lower end of the toilet bowl 40. The toilet bowl 40 is formed with a rim water passage 42 formed along the opening edge of the upper surface thereof. The upstream end of the drainage channel 41 communicates with the lower end of the toilet bowl 40, and the region from the top (highest part) of the drainage channel 41 to the lower end of the toilet bowl 40 among the upstream end of the drainage channel 41 is sealed. It is a water part 43. A vent hole 44 that opens into a space above the sealed water portion 43 is formed at a position downstream of the sealed water portion 43 in the drainage channel 41. In the drainage channel 41, a region 45 extending downward from the vent 44 is formed with a narrowed portion 45 having a reduced diameter.

  The cleaning apparatus A includes a cleaning tank 10, a water supply channel 14, a water storage unit 15, a ventilation channel 18, a cleaning water control unit 19, and an intake control unit 22. The cleaning tank 10 stores the cleaning water supplied from the ball tap 11 provided with the water supply valve 12, and the cleaning water stored in the cleaning tank 10 is supplied to the toilet bowl 40 side. It has become. A drain port 13 is formed at the lower end of the cleaning tank 10, the upstream end of the water supply channel 14 is connected to the drain port 13, and the downstream end of the water channel 14 is connected to the rim water channel 42. The cleaning water stored in the cleaning tank 10 is supplied to the rim water passage 42 through the water supply passage 14.

  The water storage unit 15 has a cylindrical shape with its upper end closed and its lower surface largely opened as a communication port 16, and is fixed inside the cleaning tank 10. The communication port 16 of the water storage unit 15 opens at a height below the storage level of the cleaning water stored before cleaning in the cleaning tank 10, and the internal space of the water storage unit 15 (the space for storing the cleaning water) is The communication port 16 communicates with the internal space of the cleaning tank 10 (the space for storing cleaning water). An intake / exhaust port 17 is formed at the upper end of the water storage unit 15 and opens at a position higher than the water storage level of the cleaning water in the cleaning tank 10. One end of the air passage 18 is connected to the intake / exhaust port 17, and the other end of the air passage 18 is connected to the air outlet 44 of the drainage passage 41. That is, the vent passage 18 communicates a position higher than the water storage level of the cleaning tank 10 in the water storage section 15 and a position higher than the water sealing section 43 in the drain passage 41.

  The washing water control means 19 includes a pump 20 provided in the middle of the water supply passage 14 and a water supply electromagnetic opening / closing valve 21. The pump 20 is for pumping the wash water stored in the wash tank 10 to the toilet bowl 40 (rim water passage 42) side, and the pump 20 has a pumping flow rate regardless of the head pressure of the wash tank 10. It has a flow control function that can be increased or decreased. That is, the flow rate of the wash water supplied from the wash tank 10 to the toilet bowl 40 can be made smaller or larger than the flow rate determined only by the head pressure of the wash tank 10. Further, when the water supply electromagnetic on-off valve 21 is opened, the supply of the wash water from the washing tank 10 to the toilet bowl 40 side is allowed. When the water supply electromagnetic on-off valve 21 is closed, the stool is supplied from the inside of the washing tank 10. The supply of cleaning water to the bowl 40 side is stopped.

  The intake control means 22 is configured by a ventilation electromagnetic on-off valve 23 provided in the middle of the ventilation path 18. When the venting electromagnetic on-off valve 23 is opened, the space on the downstream side (upper side) of the sealing portion 43 in the drainage channel 41 and the space above the wash water in the water storage portion 15 communicate with each other. It will be in the state where air can flow between. Further, when the ventilation electromagnetic opening / closing valve 23 is closed, the air flow in the ventilation path 18 is blocked.

  Next, the operation of this embodiment will be described. In the standby state before cleaning, the water supply electromagnetic on-off valve 21 is closed and the pump 20 is stopped, and the cleaning liquid is stored in the cleaning tank 10 at a predetermined water level ("water storage in the present invention and this embodiment"). Wash water is stored up to the same meaning. In addition, cleaning water is stored in the water storage unit 15 up to the same water level as the cleaning tank 10. On the other hand, in the toilet device E, the sealing portion 43 is sealed with washing water.

  From this state, when it is detected that the toilet user manually operates or the user has left the toilet bowl 40, the water supply electromagnetic on-off valve 21 is switched to the open state, and at the same time, the pump 20 is activated and the washing tank 10 and the supply of washing water from the water storage unit 15 to the toilet bowl 40 side (that is, washing in the toilet bowl 40) are started. The washing water pumped from the washing tank 10 and the water storage unit 15 to the toilet bowl 40 side is supplied into the toilet bowl 40 through the rim water passage 42 and pushes the filth in the toilet bowl 40 to the drainage passage 41 side. At this time, the wash water that has flowed into the drainage channel 41 scatters in the throttle unit 45 to form a water film, so that a siphon action occurs, and the filth in the sealed water unit 43 is discharged to the downstream side of the drainage channel 41. Is done.

  Further, at the same time as the washing water in the washing tank 10 and the water storage section 15 starts to flow out to the toilet bowl 40 side, or after the washing water starts to flow out to the toilet bowl 40, the electromagnetic on-off valve 23 for ventilation is closed. Switch from state to valve open state. When the ventilation electromagnetic opening / closing valve 23 is opened, the space above the wash water in the water storage unit 15 and the space above (downstream side) the sealing water 43 in the drainage channel 41 communicate with each other. As the water level of the wash water in 15 decreases, the air in the space downstream (upward) of the drainage channel 41 from the sealing portion 43 is sucked into the water storage unit 15 through the air passage 18. By this suction, the siphon action is enhanced, and the filth in the sealed water portion 43 is discharged to the drainage channel 41 side.

  When a predetermined amount of washing water is supplied to the toilet bowl 40, the water supply electromagnetic on-off valve 21 is closed, the pump 20 is stopped, and the supply of washing water to the toilet bowl 40 is stopped. After supplying cleaning water from the cleaning tank 10 to the toilet bowl 40 side, since cleaning water continues to be supplied from the pole tap 11 into the cleaning tank 10, the cleaning tank 10 and the water storage unit 15 The water level of the washing water rises. When the predetermined water level is reached, the water supply from the ball tap 11 is stopped, and the inside of the cleaning tank 10 and the water storage unit 15 are kept at the predetermined water storage level.

  Since the cleaning apparatus A of the present embodiment is provided with the pump 20 in the water supply path 14 as the cleaning water control means 19 for controlling the supply flow rate of the cleaning water from the cleaning tank 10 to the toilet bowl 40, the toilet bowl of the toilet apparatus E By controlling the pumping flow rate value of the pump 20 according to the shape of the drainage channel 40 and the drainage channel 41 and appropriately setting the flow rate of the washing water supplied from the washing tank 10 to the toilet bowl 40, the washing performance is stabilized. be able to.

  That is, when the toilet device E combined with the cleaning device A of the present embodiment has a configuration in which the drainage flow rate in the drainage channel 41 is increased, the pump 20 is set so that the pumping flow rate is reduced, and is supplied to the toilet bowl 40. What is necessary is just to reduce the supply flow rate of washing water. In this way, it is possible to prevent the suction of filth into the air passage 18 due to the intake force from the drainage channel 41 to the water storage section 15 becoming too strong.

  When the toilet device E combined with the cleaning device A has a configuration in which the drainage flow rate in the drainage channel 41 is reduced, the supply flow rate of the cleaning water to the toilet bowl 40 is set by increasing the pumping flow rate of the pump 20. If it increases, the washing | cleaning function which discharges | emits filth out of the toilet bowl 40 can be improved. Moreover, in this embodiment, since the position of the washing tank 10 is set to substantially the same height as the toilet bowl 40, the supply pressure of washing water due to the head pressure of the washing tank 10 cannot be increased. If the pumping flow rate by 20 is set large, even if the height of the washing tank 10 is low, the supply of washing water from the washing tank 10 to the toilet bowl 40 can be controlled stably.

  In the present embodiment, a ventilation electromagnetic on-off valve 23 is provided in the ventilation path 18 as the intake control means 22 that controls the intake operation from the drainage path 41 to the water storage section 15. If the opening / closing operation of the venting electromagnetic on-off valve 23 (intake operation from the drainage channel 41 to the water storage unit 15) is controlled according to the opening / closing operation of the water supply electromagnetic on-off valve 21 and the pumping operation of the pump 20, the washing tank 10 The siphon action can be exhibited at a suitable timing according to the supply state of the washing water from the toilet bowl 40 to the toilet bowl 40.

  For example, the stool 40 is washed in the initial stage with the pumping flow rate of the pump 20 set to a small amount, and a water film of washing water is formed in the throttling part 45. If the suction force from the water to the water storage unit 15 is increased, a strong siphon action can be generated and a high cleaning effect can be obtained. And at the end, if the pumping flow rate of the pump 20 is made small, the sealed portion 43 can be filled with the minimum required amount of washing water.

< Reference form 1 >
Next, Reference Embodiment 1 of the present invention will be described with reference to FIG. In the cleaning device B of the first embodiment, the intake control means 24 for controlling the intake operation from the drainage channel 41 to the water storage section 15 is configured differently from the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

The intake control means 24 according to the first embodiment includes an upper water storage chamber 27 and a lower water storage chamber below the upper water storage chamber 27 inside the water storage portion 15 by a partition wall 25 formed with an orifice 26 that vertically penetrates. It is comprised by dividing into 28. The height of the partition wall 25 is set at a position lower than the reservoir level of the wash water in the standby state, the intake / exhaust port 17 is opened at the upper end of the upper reservoir 27, and the lower end of the lower reservoir 28 A communication port 16 is opened in the opening. Further, in the first embodiment , the ventilation passage 18 is not provided with the ventilation electromagnetic on-off valve 23, and therefore, the space above the washing water in the water storage unit 15 and the sealing unit 43 in the drainage channel 41. The (downstream) space is always in communication.

In the first embodiment , when the supply of the washing water from the washing tank 10 to the toilet bowl 40 starts, the washing water in the washing tank 10 flows out to the toilet bowl 40 side, and the washing tank 10 other than the water storage unit 15 is vigorously flowed. The water level of the cleaning water stored in the area immediately decreases. On the other hand, in the water storage unit 15, the cleaning water that passes through the orifice 26 at the initial supply stage (that is, until the cleaning water forms a water film in the throttle unit 45) is a liquid having a relatively large flow resistance. 15 (upper water storage chamber 27), the water level lowers relatively slowly and siphon action is weak. The water level in the water storage unit 15 is designed to be lower than the partition wall 25 when a cleaning water film is formed in the throttle unit 45. When the water level in the water storage section 15 falls below the partition wall 25, air having a smaller flow resistance than the washing water passes through the orifice 26, so that the water level in the water storage section 15 (lower water storage chamber 28) is reduced. Decrease is faster and siphon action is enhanced.

  If the water level drop in the water storage section 15 is made slower than the water level drop in the washing tank 10 as described above, the washing tank 10 is reduced when the water level in the washing tank 10 falls and the washing water outflow rate decreases. The inflow flow rate of the wash water from the water reservoir 15 into the wash tank 10 may be larger than the outflow flow rate of the wash water from the inside. In this case, the difference in water level between the cleaning tank 10 and the water storage unit 15 is reduced, so that the water level lowering rate in the water storage unit 15 is slowed. As a result, the intake force from the drainage channel 41 side to the water storage unit 15 is increased. There is a concern that the siphon action will also decrease.

However, in the first embodiment , the flow rate of the wash water discharged from the wash tank 10 toward the toilet bowl 40 can be increased by the pump 20, so that the difference in water level between the wash tank 10 and the water storage unit 15 is reduced. Can be avoided, and the water level lowering speed in the water reservoir 15 can be increased. Thereby, the suction force fall from the drainage channel 41 side to the water storage part 15 can be prevented, and a strong siphon action can be maintained.

Further, in the case of slow initial drawdown in the water storage portion 15 as in this preferred embodiment 1, in order to lengthen the delay time may be reduced inside diameter of the orifice 26. However, when the inner diameter of the orifice 26 is reduced, there is a concern that foreign matters in the cleaning water may clog the orifice 26. In this respect, in the first embodiment , the washing water in the upper water storage chamber 27 is forcibly sucked to the lower water storage chamber 28 side by the pump 20 and flows out to the toilet bowl 40 side. There is no risk of it occurring.

< Reference form 2 >
Next, Reference Embodiment 2 of the present invention will be described with reference to FIG. In the cleaning device C of the second embodiment , the intake air control means 29 for controlling the intake operation from the drainage channel 41 to the water storage section 15 is configured differently from the first embodiment . Since the other configuration is the same as that of the first embodiment , the same reference numeral is given to the same configuration, and the description of the structure, operation, and effect is omitted.

In the second embodiment , a closing member 30 capable of closing the orifice 26 is accommodated in the lower water storage chamber 28 of the water storage unit 15. Since this blocking member 30 has a specific gravity smaller than that of the washing water, it is floated on the washing water in the water reservoir 15. Therefore, if the water level of the washing water in the water storage unit 15 is equal to or higher than a predetermined height, the closing member 30 closes the orifice 26 from below by buoyancy.

  When the supply of the wash water from the wash tank 10 to the toilet bowl 40 is started, the flow rate of the wash water passing through the orifice 26 at the initial stage of supply is that the closing member 30 tries to close the orifice 26 from below by buoyancy. It is squeezed compared with the case where there is no closing member 30. The flow rate when passing through the orifice 26 at this time is influenced by the buoyancy acting on the closing member 30 and fluctuates due to the difference in the level of the cleaning water in the water storage unit 15 and the cleaning tank 10.

And if the water level of the wash water in the water storage part 15 becomes lower than the lower surface of the partition wall 25, the air whose flow resistance is smaller than that of the wash water will pass through the orifice 26, so the water level in the water storage part 15 is lowered. Becomes faster and siphoning begins to work. According to the second embodiment, since the opening of the orifice 26 is narrowed by the closing member 30 while the cleaning water passes through the orifice 26, the siphon is compared with that in the first embodiment in which the closing member 30 is not provided. The timing at which the action begins to function can be delayed. Further, if the pumping flow rate of the pump 20 is reduced before the air begins to pass through the orifice 26, the water level difference between the cleaning tank 10 and the water storage unit 15 is reduced, so the flow rate of the cleaning water passing through the orifice 26 is reduced. It is also possible to delay the start of the siphon action by reducing.

< Embodiment 2 >
Next, a second preferred embodiment of the present invention with reference to FIG. The cleaning device D of the second embodiment has a configuration different from that of the first embodiment in the cleaning water control means 31 that controls the supply flow rate of the cleaning water from the cleaning tank 10 to the toilet bowl 40. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

In the second embodiment , the cleaning tank 10 is installed at a position higher than the toilet bowl, and the storage level of the cleaning water in the cleaning tank 10 and the water storage unit 15 is sufficiently higher than the toilet bowl 40. Become. Further, in the middle of the water supply passage 14, there are provided a water supply electromagnetic opening / closing valve 21 and a water supply flow rate control valve 32 disposed downstream of the water supply electromagnetic opening / closing valve 21 (toilet bowl 40 side). In this way, the washing tank 10 is installed at a position higher than the toilet bowl 40 to increase the water head pressure in the washing tank 10, and the water supply electromagnetic on-off valve 21 and the water supply flow control valve 32 are provided in the water supply path 14. The cleaning water control means 31 is configured depending on the form to be provided.

  When the water supply electromagnetic on-off valve 21 is opened, the supply of the wash water from the wash tank 10 and the water storage unit 15 to the toilet bowl 40 side (that is, the stool) due to the head pressure of the wash water in the wash tank 10 and the water storage unit 15 Since the cleaning water supplied to the toilet bowl 40 starts to wash away the filth in the toilet bowl 40 toward the drainage channel 41 and forms a water film at the throttle 45 of the drainage channel 41. Siphon action occurs. At this time, if the flow rate control valve 32 for water supply is adjusted to increase the supply flow rate of the wash water to the toilet bowl 40, the cleaning function can be improved, and the supply flow rate of the wash water to the toilet bowl 40 can be reduced. If this is the case, filth suction into the air passage 18 can be prevented. In addition, since the flushing on / off valve 23 of the ventilation path 18 is switched to the open state at the same time as the flushing water starts to flow out to the toilet bowl 40 side or after the flushing water begins to flow into the toilet bowl 40, As the cleaning water level in the section 15 decreases, the air in the drainage channel 41 is sucked into the water storage section 15 through the ventilation path 18 and the siphon action is enhanced.
