  In the thing of the said patent document 1, since the water level of the washing water collected in the bowl falls when boys are used, it is possible to prevent the urination from being rebounded on the washing water surface when boys are used, thereby preventing the above-mentioned adverse effects. There is a problem that it takes time and effort to operate the small use detection means and to raise the toilet seat when the boy is small, and it is troublesome to operate the small use detection means. If the operation is forgotten because the operation has to be performed, the small water is used at a high water level, and the function of the corner cannot be utilized.

  Further, in the above-mentioned Patent Document 1, when the wash water in the bowl is set to a low water level in the boys small mode, the bowl is prevented from being left in a low water state by performing toilet cleaning after a certain period of time. However, there is a problem that even if a person is still using it, it is washed regardless.

  The present invention has been invented in view of the above-mentioned conventional problems, and the cleaning water in the bowl is lowered to a low level only by performing an operation of erecting a toilet seat that is always performed when performing boys' urination or toilet cleaning. It is a problem to provide a toilet device that can perform boys 'urinals and toilet cleaning without any harmful effects, and does not cause any adverse effects such as washing during boys' urinals or toilet cleaning It is a problem to provide.

  In order to solve the above-described problems, a toilet device according to claim 1 of the present invention includes a toilet seat 3 provided on a bowl 2 of the toilet 1 so as to be able to be tilted up and down, and a supply path 4 of washing water to the bowl 2. A flush valve 5 that opens and closes, and a cylindrical trap portion 7 that extends from a drain port 6 at the bottom of the bowl 2 and is supported so that the free end portion of the tip end can be pivoted up and down. It is determined that it is for boys' small use or toilet cleaning when it is raised from a state where it has been tilted, and a control unit 8 is provided for controlling so that the tip of the trap unit 7 is lowered and the water level in the bowl 2 is lowered. Features. At this time, even when the water level in the bowl 2 is controlled to be lowered when it is recognized that the toilet seat 3 is upright, the water level in the bowl 2 is lowered after a certain time after recognizing that the toilet seat 3 is upright. You may come to control.

  Normally, the toilet seat 3 is tilted so as to overlap the bowl 2, but the toilet seat 3 is erected when the boy is small or when cleaning the toilet bowl. According to the said structure, when the toilet seat 3 is stood up, the front-end | tip of the trap part 7 falls below, and it controls so that a part of washing water in the bowl 2 is drained and the water level in the bowl 2 falls. As a result, it is possible to perform boys 'urging and toilet cleaning with the water level in the bowl 2 lowered, and boys' urging and toilet cleaning can be performed without any harmful effects. In this case, the water level of the bowl 2 can be lowered only by standing operation of the toilet seat 3 that is always performed when boys are used or when cleaning the toilet bowl, and it is not necessary to perform special operations as in the conventional case, so that the operation is easy. At the same time, boys are not used at high water levels and toilet bowl cleaning is not performed, so no harmful effects occur.

  Further, the toilet device according to claim 2 of the present invention recognizes the state in which the toilet seat 3 has fallen from the standing state after the control of lowering the water level in the bowl 2 by judging that it is for boys or toilet cleaning. In this case, a control unit 8 is provided for controlling the cleaning to be performed.

  According to the above configuration, the toilet seat 3 is tilted when the boy's small use is completed or the toilet bowl is cleaned, but when the toilet seat 3 is tilted, the toilet seat 3 is automatically washed. When the cleaning is automatically finished, the trap part goes up and returns to the original state, and the inside of the bowl 2 becomes a high water level.

  The toilet device according to claim 3 of the present invention is the toilet device according to claim 1, wherein the human body detecting means 9 recognizes the absence of a person after performing control for lowering the water level in the bowl 2 based on the determination for boys' use or toilet cleaning. Further, a control unit 8 is provided for controlling the toilet seat 3 so that the toilet seat 3 is tilted to perform washing.

  According to the above configuration, when the absence of a person is recognized by the human body detecting means 9 even when the operation of lowering the toilet seat 3 is not performed after the boy's urinal or toilet cleaning is completed, the toilet seat 3 is automatically depressed. Cleaning is performed automatically. As a result, the problem of forgetting the cleaning does not occur, and after the cleaning is completed, the trap portion 7 is raised to return to the original state and the inside of the bowl 2 is kept at a high water level.

  Since the present invention is constructed as described, when the toilet seat is erected for men's small use or for toilet bowl cleaning, the tip of the trap part is lowered downward, and a part of the washing water in the bowl is drained. It is controlled so that the water level in the bowl is lowered, and the boy's urine and toilet bowl cleaning can be performed with the water level in the bowl lowered, and the boy's urinal and toilet bowl cleaning should be performed without any harmful effects. In addition, it is possible to lower the water level of the bowl just by raising the toilet seat, which is always performed when boys are small or when cleaning the toilet bowl, and there is no need to perform special operations as in the past. This simplifies and does not cause any harmful effects because boys are not used at high water levels and toilet bowl cleaning is not performed. In addition, when the toilet seat is tilted after a boy's use or cleaning the toilet bowl, it is automatically washed, and after washing, the trap part rises and is maintained at a high water level, causing problems such as hygiene. There is no effect. In addition, even if you forget to knock down the toilet seat after performing a boy's urination or cleaning the toilet bowl, you can automatically defeat the toilet seat and clean it when you recognize the absence of a person using the human body detection means. Or after cleaning the toilet bowl, there is an effect of not causing the harmful effect of forgetting the cleaning.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The toilet 1 is a flush toilet equipped with toilet cleaning means for cleaning the bowl 2 with cleaning water. As shown in FIG. 1, a turn trap block 10 is provided inside a rear part of the toilet bowl 2, and a toilet control unit case 18 is provided above the part where the turn trap block 10 is provided on the rear part of the toilet bowl 1. In addition, the toilet 1 is provided with a supply path 4 for supplying cleaning water, and one end of the supply path 4 is connected to a water supply pipe such as a water pipe.

  Inside the case 11 of the turn trap block 10, a trap part 7 formed in a cylindrical shape with a deformable material is disposed, and one end of the trap part 7 is connected to the drain port 6 at the bottom of the bowl 2, The end of the trap portion 7 on the side of the free end opposite to the drain port 6 can be turned up and down. A rotation arm 12 is rotatably disposed in the case 11 of the turn trap block 10, and a rotation shaft 13 of a drive motor as a rotation drive means is connected to one end of the rotation arm 12. The other end which is the free end of the moving arm 12 is connected to the ring 14 at the tip of the trap portion 7. When the rotation shaft 13 is driven to rotate by the drive motor 24, the trap portion 7 is rotated via the rotation arm 12 and the ring 14, and the end portion on the free end side of the trap portion 7 is directed upward or downward. It has come to become.

  Further, a flush valve 5 for opening and closing the supply path 4 is provided in the toilet control unit case 18 and a control unit 8 for performing various controls of the toilet 1 is provided. A rim 16 is provided at the periphery of the upper end of the bowl 2, and a plurality of fountain holes are drilled in the rim 16, and when the cleaning valve 5 is opened and water is supplied to the supply passage 4, the rim 16 is passed through the rim 16. Wash water is ejected from the fountain hole into the bowl 2. A toilet seat 3 and a toilet lid 15 are disposed on the bowl 2 of the toilet bowl 1, and the front ends of the toilet seat 3 and the toilet lid 15 are rotatably connected so that the toilet seat 3 and the toilet lid 15 can be tilted up and down. It has become. It is desirable that the toilet seat 3 can be electrically driven by a toilet seat electric drive block 25.

  When the bowl 2 is washed with the toilet 1 as described above, the operation is as follows. FIG. 2A shows a state when cleaning of the bowl 2 is started, and the tip of the trap portion 7 is rotated so that the tip is directed upward, and the cleaning water is held in the bowl 2 at a high water level. . When cleaning is started, the cleaning valve 5 is opened, water is supplied from the supply path 4, and cleaning water is jetted into the bowl 2. Then, the tip of the trap part 7 is rotated from the state in which the tip of the trap part 7 faces upward, so that the tip of the trap part 7 faces down, and the tip of the trap part 7 faces down as shown in FIGS. Thus, the water in the bowl 2 is drained from the trap portion 7 at a stretch. After draining the water in the bowl 2 at once, it is rotationally driven so that the tip of the trap part 7 faces upward, and the washing water is held so that the inside of the bowl 2 becomes a high water level, and is ready for the next use. Although cleaning is performed as described above, when cleaning after stool, by turning on the large cleaning button, the cleaning valve 5 is opened and the cleaning water is supplied for a long time. When washing after urination, the washing valve 5 is opened and the washing water is supplied for a short time by turning on the small washing button.

  Although the toilet 1 is configured as described above, in the present invention, the controller 8 controls the flush water level in the bowl 2 to be low when boys are small or when the toilet is cleaned. That is, the height of the tip of the trap portion 7 is lowered to the lower position as shown in FIG. 1B than the upper end position of FIG. Thus, the water level of the wash water in the bowl 2 can be kept at a low position.

  FIG. 3 is a block diagram of the control. Although the toilet seat 3 can be tilted up and down, the toilet seat upper position detection sensor 20 detects when the toilet seat 3 is raised, and the toilet seat lower position detection sensor 21 detects when the toilet seat 3 is tilted. . Also, the presence or absence of a human body in the toilet room is detected by an indoor human body detection sensor 9a as the human body detection means 9. Further, the drainage trap sensor 22 detects the height position of the tip of the trap portion 5. Detection information of the toilet seat upper position detection sensor 20, the toilet seat lower position detection sensor 21, the indoor human body detection sensor 9a, and the drain trap sensor 22 is input to the control unit 8, and the control unit 8 drives the toilet seat electric drive block 25. Control of opening / closing of the water supply valve 5, driving of the drive motor 24 of the trap unit 7, and on / off of the deodorizing device 23 can be performed.

  Next, the operation will be described with reference to the flowchart of FIG. When entering the toilet room, the presence of a person is detected by the indoor human body detection sensor 9a. In this state, when the toilet seat 3 is raised for boys' use or toilet cleaning, it is detected by the toilet seat upper position detection sensor 20 that the toilet seat 3 is raised and positioned at the upper position. As a result, the drive motor 24 is driven by the control unit 8 so that the tip of the trap unit 7 is lowered, a part of the water in the bowl 2 is discharged, and the water level in the bowl 2 is lowered. At this time, if it is recognized that the toilet seat 3 has stood up, the water level in the bowl 2 will be controlled after a certain period of time has elapsed after recognizing the standing state of the toilet seat 3 even if the water level in the bowl 2 is controlled to drop. You may make it perform control which falls.

  If the water level in the bowl 2 can be controlled to be lowered when the toilet seat 3 is erected as described above, it is possible to reduce water splashing when the boy is small, and to clean the toilet bowl with a detergent. It becomes easy to clean the draft surface. Moreover, since the water level in the bowl 2 can be controlled to be lowered by raising the toilet seat 3, the water level in the bowl 2 can be lowered without any special operation. Never forget to lower the water level when cleaning the toilet bowl.

  As described above, when the toilet seat 3 is erected and the water level in the bowl 2 is lowered, the deodorizing device 23 is turned on to deodorize the toilet room. Normally, the deodorizing device 23 is turned on to deodorize the toilet room when sitting on the toilet seat 3 with the toilet seat 3 tilted down. Therefore, when the toilet seat 3 is erected, the deodorizing device 23 is turned on so that the toilet room is deodorized. When the deodorizing device 23 is turned on in this way, it is possible to reduce the odor for small boys and the smell of detergent when cleaning the toilet to the user, thereby enabling boys' toilet and toilet cleaning more comfortably. .

  When the toilet seat 3 is tilted after the boy's small size or the toilet bowl is cleaned with the water level in the bowl 2 lowered, the toilet seat 3 is tilted by the toilet seat lower position detection sensor 21 and is positioned at the lower position. Detected. As a result, the cleaning valve 5 is opened and the drive motor 24 is driven so that the tip of the trap portion 7 is lowered and cleaning is performed. At this time, if it is recognized that the toilet seat 3 has fallen from the standing state, even if the bowl 2 is washed, it is recognized that the toilet seat 3 has fallen from the standing state, and the bowl 2 is washed after a predetermined time. You may do it. When the bowl 2 is washed in this manner, the bowl 2 is washed by tilting the toilet seat 3 after finishing the boy's small use or after cleaning the toilet bowl. When the cleaning of the bowl 2 is completed, the trap position is returned so that the height of the tip of the trap portion 7 is located at the upper end position, and the inside of the bowl 2 is held at a high water level. Maintaining a state where the water level in the bowl 2 is low and the sealing water level is low for a long time as described above is not preferable in terms of hygiene and safety in consideration of pressure fluctuations in the drain pipe, but the water level is increased after cleaning. If this is possible, hygiene safety can be reliably maintained.

  The bowl 2 is washed when the toilet seat 3 is tilted after finishing the boy's small use or toilet cleaning as described above, but when leaving the toilet room without tilting the toilet seat 3 When an unattended person is detected by the indoor human body detection sensor 9a and a certain time (for example, 1 minute) elapses after the absence, the toilet seat electric drive block 25 is driven, the toilet seat 3 is tilted, and the toilet lid 15 is closed. At this time, since the toilet seat 3 falls, if it is recognized that the toilet seat 3 has fallen, washing is automatically performed. This makes it easy to wash the bowl 2 even if you forget to push down the toilet seat 3 after cleaning the toilet or cleaning the toilet, or forget to press the large or small washing button. In addition, the water level of the bowl 2 can be increased and the sanitary safety can be reliably maintained by sealing water.

  In addition, when the washing button is pushed after finishing the boy's small use or toilet cleaning as described above, the washing button is given priority for washing. In other words, even when the large cleaning button is pressed to perform a large cleaning or the small cleaning button is pressed to perform a small cleaning, priority is given to the operation of the cleaning button so that the cleaning is not performed twice. At this time, the small washing button is pressed to perform small washing when boys are used, and the large washing button is pressed to perform large washing when toilet cleaning is performed.

  Further, as described above, the toilet seat 3 is erected in order to use for boys or to clean the toilet bowl. At this time, when the toilet seat upper position detection sensor 20 recognizes that the toilet seat 3 is erected, from that time onwards. Measure the time until the toilet seat 3 is knocked down, and if it is over a certain period of time until the toilet seat 3 is pushed down, it is judged that the toilet has been cleaned, and if it is within the fixed time, the boys are used Judgment is made so as to perform small cleaning. As a specific example, when the toilet seat 3 is erected and the position on the toilet seat is held for 2 minutes or more, large washing is performed, and when the position on the toilet seat is within 2 minutes, small washing is performed. In this case, it is possible to automatically determine whether it is for boys' small use or toilet cleaning and perform appropriate washing.

  In addition, as described above, washing is performed after the boy 2 is used with the water level of the bowl 2 lowered or the toilet bowl is cleaned. At this time, the tip of the trap portion 7 is temporarily lifted including the normal position. It is also preferable to carry out washing after raising the temperature. It is also preferable to perform cleaning from the position of the tip of the trap part 7 as it is or further lowered.

An example of embodiment of this invention is shown, (a) is sectional drawing of the state where a trap part is a normal state, and a bowl is in a high water level, (b) is a toilet seat upright, a trap part falls from a normal state, and a bowl is It is sectional drawing of the state of a low water level.
