Since there is no washing water at the draft surface position, dirt adhering to the vicinity of the draft surface can be cleaned without touching the washing water.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. First, a basic configuration of the toilet device will be described.

  The toilet bowl 1 is provided with washing water supply means 2 for supplying water to the bowl portion 11. The toilet 1 includes a turn trap block 50 inside the rear portion thereof, and a toilet control case 12 is provided at a position above the rear portion of the toilet 1 where the turn trap block 50 is disposed. The toilet 1 is provided with a water supply pipe 20, and the upstream end of the water supply pipe 20 is connected to a water supply (not shown), thereby forming the washing water supply means 2. The toilet 1 includes an air mixing means 3 and a detergent supply means 4, which will be described later.

  A movable turn trap 51 made of a deformable material is provided in the case of the turn trap block 50, and one end of the turn trap 51 is connected to the outlet of the bowl portion 11. The turn trap 51 is movable between a posture in which the opening 51a at the downstream end of the turn trap 51 faces upward and a posture in which the turn trap 51 faces downward by a drive motor (not shown) provided on the case outer surface side of the turn trap block 50. ing.

  In the toilet control unit case 12 provided on the upper surface side of the rear portion of the toilet 1, an electromagnetic valve 21 is provided in the middle of the water supply pipe 20, and a control unit for controlling the electromagnetic valve 21 and the drive motor (FIG. (Not shown), and a trap position sensor (not shown) for detecting whether the opening 51a at the downstream end of the turn trap 51 faces upward or downward is provided. Then, the toilet valve washing means for washing the bowl part 11 with water is constituted by the electromagnetic valve 21, the drive motor for driving the turn trap 51, and the trap position sensor.

The basic operation of toilet cleaning by the toilet cleaning means will be described. FIG. 2 shows an example of toilet cleaning operation by the toilet cleaning means in this embodiment. FIG. 2A shows a state in which the toilet flushing means is off, that is, a state in which the stored water W is formed in the toilet 1 (standby state). In this state, the opening 51a at the downstream end of the turn trap 51 is upward. The water is accumulated in the turn trap 51 and the bowl portion 11 and the level of the opening 51 a at the downstream end of the turn trap 51 is the same level as the normal draft surface S ₀ of the bowl portion 11. When toilet flushing is started in this state, first, the electromagnetic valve 21 is opened and water flows out to the bowl portion 11 as shown by an arrow A in FIG. Next, as shown in FIG. 2B, the drive motor is rotated forward so that the level of the opening 51a at the downstream end of the turn trap 51 is lowered to the lower end of the bowl portion 11 or lower (referred to as a drainage position). The turn trap 51 is rotated so that 51 a faces downward, and the water 11 in the bowl portion 11 and the turn trap 51 is discharged from the opening 51 a at the downstream end of the turn trap 51, so that filth is discharged together with the stored water W. . Next, the opening 51a level of the downstream end of the opening 51a becomes a normal draft surfaces S ₀ level and the same level of the bowl portion 11 of reversed drive motor turns the trap 51 is rotated turn traps 51 So that is facing up. During this time, even when the solenoid valve 21 is open and the opening 51a at the downstream end of the turn trap 51 faces upward, water is supplied into the bowl portion 11, and the opening 51a is again opened as shown in FIG. When water accumulates in the turn trap 51 and the bowl portion 11 facing upward, the electromagnetic valve 21 is closed, and a state (standby state) in which the accumulated water W in FIG.

  The air mixing means 3 is configured by connecting an air intake pipe 31 to the downstream side of the solenoid valve of the water supply pipe 20, whereby air in the atmosphere is mixed as bubbles. If the connection part of the air intake pipe 31 in the water supply pipe 20 is formed in the throttle part which restrict | squeezed the water supply pipe 20, suction will be performed efficiently by a negative pressure.

  In this embodiment, the detergent supply means 4 is branched from the detergent tank 41, the circulation channel 42 connected to both ends of the detergent tank 41, the pump 43 disposed in the circulation channel 42, and the circulation channel 42. And a branch supply passage 44 connected to the water supply pipe 20. The detergent circulates in the circulation channel 42 from the detergent tank 41 and returns to the detergent tank 41 again by driving the pump 43, but a part of the detergent is supplied from the branch supply channel 44 to the water supply pipe 20. The branch supply flow path 44 is branched from the middle of the circulation flow path 42 and connected to the downstream side of the portion where the air intake pipe 31 of the water supply pipe 20 is connected, and the branch supply flow path 44 of the water supply pipe 20 is connected. Is connected to a throttle portion such as a venturi throttle so that the detergent can be efficiently sucked into the water supply pipe 20 by a negative pressure.

  By the aeration means 3 and the detergent supply means 4, cleaning water containing detergent mixed with micrometer-sized (μ size) microbubbles and detergent-free cleaning mixed with millimeter-sized (m size) bubbles are used. Water can be generated arbitrarily. This is because when the cleaning water supply means 2 is driven by driving the pump 43 of the detergent supply means 4, the detergent is mixed and dissolved in the cleaning water mixed with air from the air mixing means 3, and the dissolved detergent (surface-active The surface tension of the washing water is reduced by the agent), and the air in the washing water becomes microbubbles of 50 to 60 μm by shearing and stirring, and the washing water containing the detergent mixed with the microbubbles is obtained.

  On the other hand, when the cleaning water supply means 2 is driven without driving the pump 43 of the detergent supply means 4, the cleaning water mixed with air is supplied from the air mixing means 3 to the bowl portion 11, and the cleaning in this case is performed. The water in the washing water becomes bubbles of 3 to 5 mm larger than the above-mentioned fine bubbles by shearing and stirring, and the washing water without detergent mixed with bubbles is obtained.

  Since the washing water without detergent mixed with bubbles has a larger fluctuation in microscopic flow rate when the washing water flows through the bowl portion 11, the inner surface of the bowl portion 11 of the toilet 1 is thereby reduced. Dirt adhered to the surface can be removed, but the bubbles almost disappear with a short axis (2 to 3 minutes).

  On the other hand, the washing water without detergent mixed with bubbles has a smaller fluctuation in microscopic flow rate when the washing water flows into the bowl part 11 than the bubbles, so Although the effect of removing dirt adhering to the inner surface of the bowl portion 11 is low, the bubbles exist for a long time (several hours). The microbubbles adhere to dirt adhering to the inner surface of the bowl portion 11, and the dirt is peeled off from the inner surface of the bowl portion 11 by the buoyancy of the microbubbles, or the microbubbles burst near the draft surface S on the inner surface of the bowl portion 11. By doing so, the dirt adhering to the vicinity of the draft surface S is peeled off and removed.

  The basic operation by toilet cleaning is as described above, but in this embodiment, the detergent-free cleaning water mixed with bubbles and the cleaning water containing detergent mixed with microbubbles are used separately and discharged. A toilet flushing (hereinafter referred to as “large washing”) during stool cleaning with toilet bowl and a urinal washing (hereinafter referred to as “small washing”) during urination are described below.

  The large cleaning is started when the large cleaning is turned ON by operating the operation unit or when the large cleaning is turned ON by the automatic cleaning mode. Here, the operation unit is not particularly limited, and is provided on the toilet device or transmits a command to the toilet device from a part separated by wire or wirelessly. A command is transmitted to the control unit by an input from the operation unit. In the automatic washing mode, a seating sensor that detects seating is provided on the toilet seat, and when the seating sensor detects seating due to the toilet, and the seating after the toilet is detected, a command for large washing is automatically sent to the control unit. Is to send.

When the large cleaning is started, as shown in FIG. 3, the supply of cleaning water is started by the cleaning water supply means 2. At this time, the detergent supply means 4 is not driven, and cleaning water without detergent mixed with bubbles is supplied. Then, a large cleaning start from a predetermined time when T ₁ is passed, and the level is lowered at the lower end of the turn trap 51, a state located in the lower end position as shown in FIG. 2 (b) over the fall time Tl bowl portion 11, the filth is discharged together with the washing water. Then, after holding during the state located at the lower end position of the predetermined time T _2, the level of the lower end portion is raised in turn trap 51, comprising over rise time Tu and normal draft surface position S ₀ at the same level. Then, by driving the detergent supply unit 4 after a predetermined time T _3, the washing water supplied to the bowl portion 11 is the wash water containing detergent microbubbles are mixed. Then after a predetermined time T _4, the detergent supply unit 4 stops, after further ₅ predetermined time T, the supply of the cleaning water by cleaning water supply means 2 is stopped, a large washing ends. As a result, when the cleaning water is made to flow into the bowl portion 11, dirt that adheres to the inner surface of the bowl portion 11 of the toilet bowl 1 is removed by bubbles larger than the microbubbles, and then the cleaning water accumulates in the bowl portion 11 as accumulated water. In this state, dirt attached to the inner surface of the bowl portion 11 for a long time can be removed by the microbubbles.

Also, is the same as basically the large flushing partial flushing, the predetermined time is a predetermined time T ₁ is small flushing _{T 1 '(T 1'<} T 1) in a large _washing, a predetermined time in the full flushing T ₂ However, the difference is that the predetermined time T ₂ ′ (T ₂ ′ <T ₂ ) is obtained in the small cleaning.

In the present invention, the cleaning mode is enabled by the control unit. In the cleaning mode, the normal draft surface position S _{0 on} the inner surface of the bowl portion 11 can be seen, and the dirt near the normal draft surface position S _{0 on} the inner surface of the bowl portion 11 can be wiped and cleaned without dirtying hands with washing water. as it can and holds a state in which lower than the normal waterline surface position S ₀ a draft surface S of the bowl portion 11. In the present embodiment, as shown in the time chart of FIG. 4, when the cleaning mode start command is transmitted to the control unit by the operation of the operation unit, the level at the downstream end of the turn trap 51 is set to the normal draft surface position S. _In this case, the turn trap 51 serves as the draft level lowering means 5. The draft surface lowering means 5 includes, in addition to the turn trap 51, a bowl portion 11 provided with a drain bypass path and a valve in the bypass path, or a bowl facing toward a cyclone wrap behind the bowl portion 11. Examples include a so-called siphon jet type that ejects a jet jet into the water stored in the portion 11 and discharges the water stored in the bowl 11 from the jet path of the jet jet.

In this cleaning mode, an operation for transmitting a command to end the cleaning mode is performed from the operation unit, or a command to end the cleaning mode is transmitted to the control unit due to the time-up of the cleaning mode end timer function. Then, the operation for finishing the cleaning mode is performed and the process is finished. The operation for ending the cleaning mode is to raise the downstream end of the turn trap 51 to the normal draft surface position S ₀ and to wash the amount of water for returning to the normal draft surface position S ₀ by the wash water supply means 2. Supply water. Thus, the draft surface S in a standby state back to a normal draft surface position S _0.

According to the configuration as described above, it has to hold the state in which the draft surface S of the washing water during cleaning mode of operation the control unit is lowered than usual draft surface position S _0, mixed in the wash water tends, also, the inner surface of the bowl portion 11 has been has bubbles to clean so normal draft surface position S ₀ of the inner surface of the bowl portion 11 down from the position of the normal waterline surface position S ₀ looks Since there is no washing water at the normal draft surface position S ₀ , dirt adhering to the vicinity of the draft surface S can be cleaned without touching the washing water.

Further, as another embodiment, as shown in FIG. 5, at the start of the cleaning mode, detergent-free washing water mixed with bubbles may be supplied to the bowl portion 11 for a certain period of time or a certain amount. This is because the cleaning water is supplied to the bowl portion 11 by the cleaning water supply means 2 when the cleaning mode start command is transmitted to the control portion by the operation of the operation portion, and then the level at the downstream end of the turn trap 51 is set. is to hold the normal state the draft surface S is lowered than the level of the waterline plane position S ₀ is lowered than the normal waterline surface position S _0.

Thus, to foam-breaking normal (including microbubbles) bubbles adhering to the vicinity of draft surface position S ₀ or washed away or remove the inner surface of the bowl portion 11, the air bubbles are located draft surface S It is possible to make the vicinity of the normal draft surface position S _{0 on} the inner surface of the bowl portion 11 even easier to see. Also, to remove the dirt adhering to the vicinity of the normal waterline surface position S ₀ of the inner surface of the bowl portion 11 of the toilet bowl 1 at larger bubbles than microbubbles when flowing cleaning water to the bowl portion 11 as described above, then in that washing water can remove dirt adhering to the vicinity of the normal waterline surface position S ₀ of the inner surface of the bowl portion 11 for a long time by microbubbles in the state accumulated as accumulated water in the bowl portion 11 , it can be further easily seen more normal draft surface vicinity of the position S ₀ wash away microbubbles staying for a long time.

As another embodiment, when the command to the control unit the end of the cleaning mode may be controlled by the control unit to return the draft plane S to the normal draft surface position S ₀ performs full flushing. Recently, the bowl part 11 of the toilet 1 is often cleaned by wiping with a disposable cloth made of paper or the like, and after the cleaning is finished, the cloth is thrown into the bowl part 11 of the toilet 1 and washed as filth. For this reason, when the control unit is instructed to end the normal cleaning mode of the bowl part 11 after the cleaning mode is completed, it is preferable to clean the bowl part 11 in which dirt such as a cloth is accumulated, It is preferable to carry out by large washing with strong force (that is, a large amount of washing water). Thereby, washing | cleaning in the bowl part 11 in which dirts, such as a cloth cloth, are collected by large washing | cleaning, and the dirt in the bowl part 11 can be discharged | emitted reliably.

Here, when the operation unit is operated to manually transmit the cleaning mode end command, the operation unit may be an operation unit for large cleaning or an operation unit for small cleaning. As a result, only the large cleaning or small cleaning operation unit is operated with the intention of flowing the filth such as the cloth in the bowl portion 11 after the cleaning is completed, and the turn trap 51 returns to the original state and the draft surface S becomes normal. with return to draft surface position S _0, in which it is possible to reliably discharge the waste in the bowl portion 11 by the large flushing.
