JP 2004-68278 A

  However, in the toilet cleaning device as in Patent Document 1, since the cleaning water is sprayed into the bowl portion, there is a problem that the portion that becomes the blind spot of the spray tends to be incompletely cleaned.

  For this reason, a method of cleaning the inside of the bowl part using mist is also conceivable, but when the toilet lid is closed, the inside of the bowl part is airtight, so that the mist is difficult to diffuse, so cleaning is also incomplete. There is a problem that it is easy to become.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a toilet bowl that can be washed in the bowl part and in every corner of the toilet lid and toilet seat facing the bowl part.

  In order to solve the above-mentioned problems, the present invention provides a toilet bowl provided with a toilet lid that covers the upper portion of the bowl portion of the toilet body together with the toilet seat portion, and sucks and discharges the air in the bowl portion to the outside when the toilet lid is closed. Thus, the decompression device for decompressing the inside of the bowl portion, the cleaning agent supply device for supplying the floating cleaning agent into the bowl portion, the cleaning agent is supplied from the cleaning agent supply device during decompression of the bowl portion by the decompression device, and the cleaning agent And a control device for stopping the decompression of the decompression device after a lapse of a predetermined time from the stop of the supply of the toilet.

  According to a second aspect of the present invention, the floating detergent is preferably any one of mist, mist carrying a detergent, steam, ozone, or minute water droplets carrying ions.

  According to a third aspect of the present invention, the pressure reducing device can be configured to be an aspirator that performs suction and discharge using water flow pressure.

  According to a fourth aspect of the present invention, the air sucked and discharged to the outside by the pressure reducing device is preferably discharged to a drainage channel that drains the sealed water in the bowl portion to the outside.

  According to a fifth aspect of the present invention, the pressure reducing device can be a vacuum pump.

  As in claim 6, when the toilet lid is opened during the supply of the floating cleaning agent, the supply of the floating cleaning agent is stopped, and then the suction and discharge is continued for a predetermined time. It is preferable to control to stop the decompression device later.

  According to the present invention, when the toilet lid is closed, the pressure in the bowl portion is reduced by sucking and discharging the air in the bowl portion to the outside, and the cleaning agent is supplied from the cleaning agent supply device, whereby the reduced pressure in the bowl portion is obtained. Since the cleaning agent is easily diffused, it becomes possible to clean the inside of the bowl part and every corner of the toilet lid and toilet seat facing the bowl part. In addition, since the decompression of the decompression device is continued until a predetermined time has elapsed from the stop of the supply of the cleaning agent, the cleaning agent remaining in the bowl portion is sucked and discharged together with the air. When the toilet lid is opened, there is no possibility that the cleaning agent floating in the bowl will be scattered around.

  According to claim 2, the cleaning performance is improved by using mist or the like as the floating cleaning agent.

  According to the third aspect, by using the aspirator that performs suction and discharge using the water flow pressure, the pressure reducing device is simple and inexpensive.

  According to claim 4, by discharging the air sucked and discharged outside by the decompression device to the drainage channel, compared with the case of discharging into the toilet room through the blower fan or filter, Since no processing equipment is required, the cost is reduced.

  According to the fifth aspect, by using the vacuum pump that performs suction and discharge using electric power, the suction and discharge force and the suction and discharge time can be easily controlled.

  According to the sixth aspect, even when the toilet lid is opened during the supply of the floating cleaning agent, after the supply of the cleaning agent is stopped by the control device, the suction and discharge are continued for a predetermined time, and then the decompression device is stopped. By doing so, the floating cleaning agent in the bowl portion is sucked and discharged, and the possibility of scattering around is reduced.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the toilet 1 includes a toilet body 4 in which a bowl portion 3 is formed inside a skirt portion 2. The toilet body 4 may be made of synthetic resin or ceramic. Sealed water (reserved water) is stored in the bowl portion 3 at a constant water level L1.

  The toilet seat 5 and the toilet lid 6 are disposed above the bowl portion 3, and the toilet seat 5 and the toilet lid 6 are supported by the toilet body 4 by the hinge portion 7 so as to be freely opened and closed. The toilet seat 5 may be formed integrally with the toilet body 4.

  The toilet lid 6 is formed in a box shape so as to cover the upper part of the bowl portion 3 of the toilet body 4 together with the toilet seat 5, and is formed at the lower end of the outer peripheral wall 6 a of the toilet lid 6 as shown in detail in FIG. A packing 8 is attached to abut the upper surface of the toilet body 4 in the closed position and keep the inside of the toilet lid 6 airtight. 2 (b), a packing (foot rubber) 9 that contacts the upper surface of the toilet body 4 is attached to the lower surface of the toilet seat 5, and a packing 8 attached to the lower end of the outer peripheral wall 6a of the toilet lid 6 is attached. The inside of the toilet lid 6 can be kept substantially airtight by contacting the upper surface of the toilet seat 5.

  A low tank 10 is attached to the rear part of the toilet body 4, and tap water (wash water) is supplied to the low tank 10 from a tap water pipe 11. The tap water pipe 11 is provided with an on-off valve 12 for supplying / stopping tap water (wash water).

  A turn trap mechanism 15 is disposed in the toilet body 4. The turn trap mechanism 15 includes a bellows-shaped trap hose 16 having one end connected to the discharge pipe 3a of the bowl portion 3, a tip ring member 16a attached to the other end of the trap hose 16, and a motor (not shown). ) And an arm member 17a that transmits the rotation of the rotation shaft 17 to the tip ring member 16a.

  As shown in FIG. 1, the trap hose 16 is normally held in an upward position in the dome-shaped cover 14 in the toilet body 4, and seal water (reserved water) is fixed between the bowl portion 3 and the trap hose 16. It can be stored at the water level L1.

  When the water washing operation is performed with a lever, a push button switch or the like, the washing water in the raw tank 10 is discharged into the bowl portion 3 from the discharge portion 18a of the washing water supply pipe 18 (see arrow a). .

  At the same time, in the turn trap mechanism 15, the rotation shaft 17 is rotated around the counter hour hand in FIG. 1 by driving the motor, and the trap hose 16 is rotated downward (see arrow b) via the arm member 17 a and the tip ring member 16 a. Therefore, the sealed water between the bowl portion 3 and the trap hose 16 is drained from the drainage channel 19 to the external sewer pipe together with the filth.

  After that, the trap hose 16 is rotated upward at a constant timing, and the sealed water (reserved water) is again stored at the constant water level L1 in the bowl portion 3 and the trap hose 16 with the upward position held. Become.

  On the other hand, the toilet body 4 is provided with a decompression device 22 for reducing the pressure by sucking and discharging the air in the bowl portion 3 which is kept substantially airtight by closing the toilet lid 6.

  For example, an aspirator 23 that performs suction and discharge using water flow pressure can be used as the decompression device 22.

  As shown in detail in FIG. 3, the aspirator 23 includes a watertight container 24, which is partitioned into an upper chamber 24 a and a lower chamber 24 b by a partition plate 25. A branch pipe 26 branched from the tap water pipe 11 is connected to the lower chamber 24b via an on-off valve 27 (see FIG. 1) so that the tap water is stored in the lower chamber 24b at a certain water level L2. It has become.

  A pump 28 is disposed in the upper chamber 24a, and the suction pipe 28a and the discharge pipe 28b of the pump 28 face the stored water in the lower chamber 24b. Here, the discharge pipe 28b is set shallower (shorter) than the suction pipe 28a, and is set closer to the air discharge pipe 31 described later than the suction pipe 28a. As a result, there is no possibility that air (odor) discharged from the discharge pipe 28b into the stored water in the lower chamber 24b will be re-inhaled into the suction pipe 28a, and the air discharge pipe 31 is smoothly discharged.

  The other end of the air discharge pipe 31 having one end connected to the side wall of the lower chamber 24b is connected to the dome-shaped cover 14 (that is, the drainage channel 19). Thus, by connecting the other end of the air discharge pipe 31 to the dome-shaped cover 14, the connection can be easily performed as compared with the case of connecting the other end of the air discharge pipe 31 to a normal S-shaped trap. In addition, by connecting one end of the air discharge pipe 31 to the side wall of the lower chamber 24b, the stored water exceeding the connection port of the air discharge pipe 31 overflows and is discharged, so that the lower chamber 24b is maintained at a constant water level L2. Will come to be.

  Further, the toilet body 4 is provided with a mist supply device 35 for supplying mist (floating cleaning agent) into the bowl portion 3 as shown in FIG.

  The mist supply device 35 is installed outside the toilet 1 and includes a detergent liquid storage tank 36 and a mist generator 37.

  The detergent liquid storage tank 36 stores a detergent liquid for generating a cleaning liquid in the mist generator 37, and the bottom of the detergent liquid storage tank 36 and the top of the mist generator 37 are connected via an opening / closing valve 39. A detergent solution supply pipe 38 communicates.

  The mist generator 37 has a liquid tank 40 for storing washing water. One end of the toilet communication pipe 41 is connected to the upper end of the liquid tank 40, and the other end of the toilet communication pipe 41 is the duct part 4 a of the toilet body 4. It is communicated to. A fan 48 and a heater 49 of the hot air dryer 47 are disposed in the duct portion 4a.

  An ultrasonic transducer 42 is attached to the bottom of the outer wall of the liquid tank 40, and a heater 43 for adjusting the temperature of the mist by heating the cleaning water is disposed inside the liquid tank 40.

  A water supply pipe 44 branched from the tap water pipe 11 (see FIG. 1) is connected via an opening / closing valve 45 to a position below the joining position of the detergent liquid supply pipe 38 in the upper part of the liquid tank 40.

  Accordingly, the on-off valve 39 is opened to supply the detergent liquid in the detergent liquid storage tank 36 from the detergent liquid supply pipe 38 to the liquid tank 40 of the mist generator 37, and the on-off valve 45 is opened to supply tap water from the water supply pipe 44. By supplying it to the tank 40, the detergent solution is diluted with water to a predetermined concentration to produce a cleaning solution. When rinsing the toilet 1 is performed, only tap water may be supplied to the liquid tank 40 of the mist generator 37.

  The ultrasonic transducer 42 generates fine particle mist having a mist diameter of about 0.1 to 50 μm, for example, by ultrasonically vibrating the cleaning liquid by a drive signal applied from a transmitter (not shown). At that time, by heating the cleaning liquid to a predetermined temperature by the heater 43, the generation of mist is further facilitated, and the mist generator 37 can efficiently generate mist. The mist generator 37 is not limited to the ultrasonic vibrator 42, and for example, a steam generator or a pressure sprayer can be used.

  If the toilet bowl 1 is configured as described above, when the toilet bowl 1 is used and washed with water using a lever, a push button switch, or the like, the sealing water between the bowl portion 3 and the trap hose 16 becomes filth as described above. At the same time, after drained from the drainage channel 19 to the external sewer pipe, the sealed water (reserved water) is again stored in the bowl portion 3 and the trap hose 16 at a constant water level L1.

  Thereafter, when it is detected by a sensor or the like that the toilet lid 6 is in the closed position, the pump 28 of the aspirator 23 is driven by a control signal from the control device 33 such as a microcomputer, and the stored water in the lower chamber 24b is sucked into the suction pipe. The circulation of suction from 28a and discharge from the discharge pipe 28b is repeated (see arrow c).

  If the sensor or the like detects that the amount of stored water in the lower chamber 24b has decreased below a certain water level L2, the on-off valve 27 is opened by a control signal from the control device 33, and the branch pipe 26 is connected to the tap water pipe 11. Thus, tap water can be supplied into the lower chamber 24b (see arrow e). As described above, the stored water in the lower chamber 24b is basically used for circulation, and only needs to be replenished when the water level drops below a certain level L2.

  When a water flow is generated in the discharge pipe 28b as the pump 28 is driven, the air suction pipe 30 becomes a negative pressure due to the water flow pressure, so that air in the bowl portion 3 is sucked and discharged from the air suction pipe 30 (arrow) f)), the inside of the bowl portion 3 is decompressed. Even if the toilet lid 6 is closed, the inside of the bowl portion 3 is not completely airtight, and a slight gap is usually generated. By being sucked into the portion 3, an air flow is generated in the bowl portion 3, and the air in the bowl portion 3 can be smoothly sucked and discharged from the air suction pipe 30. In some cases, a slight gap can be positively formed.

  The air sucked and discharged from the bowl portion 3 by the air suction pipe 30 is mixed with the water flow flowing through the discharge pipe 28b and discharged into the stored water in the lower chamber 24b, and this air floats on the water surface of the stored water and partitions. It collects with the plate 25 (the space between the upper surface of the water level L2 and the lower surface of the partition plate 25 becomes an air (odor) layer), and is discharged from the air discharge pipe 31 to the drainage channel 19, that is, the external sewer pipe. (See arrow d).

  In response to the timing at which the inside of the bowl portion 3 is depressurized, the on / off valve 39 is opened by a control signal from the control device 33 to supply the detergent liquid in the detergent liquid storage tank 36 to the liquid tank 40 of the mist generator 37 and open / close. The valve 45 is opened and tap water is supplied to the liquid tank 40 to produce a cleaning liquid.

  Then, the ultrasonic vibrator 42 of the mist generator 37 is vibrated by a control signal from the control device 33, and the cleaning liquid in the liquid tank 40 of the mist generator 37 is atomized to generate mist. At that time, by heating the cleaning liquid to a predetermined temperature with the heater 43, mist generation is further facilitated, mist can be efficiently generated in the mist generator 37, and diffusibility and cleaning power are improved. Can do.

  The mist generated in this way is discharged to the duct part 4a of the toilet body 4 through the toilet communication pipe 41 and further sprayed into the bowl part 3 from the duct part 4a (see arrow g).

  Thereby, when the toilet lid 6 is closed, the pressure in the bowl portion 3 is reduced by sucking and discharging the air in the bowl portion 3 to the outside by the pressure reducing device 22, and the pressure is reduced by supplying the mist from the mist supply device 35. Since the mist is easily diffused inside, the bowl part 3 and the toilet lid 6 and the corners of the toilet seat 5 facing the bowl part 3 can be washed. During mist cleaning, the fan 48 of the hot air dryer 47 is actively rotated to adjust the amount of mist discharged, thereby concentrating the action of the mist or improving the contact efficiency of the mist into the bowl portion 3. You may adjust it.

  After the mist cleaning is performed for a predetermined time (for example, 10 minutes), the rinsing cleaning is started. At that time, the on-off valve 39 is closed and no detergent solution is supplied to the liquid tank 40 of the mist generator 37, and only the tap water is supplied to the liquid tank 40 of the mist generator 37 by opening the on-off valve 45. Then, the ultrasonic vibrator 42 of the mist generator 37 is vibrated and the mist generated in the liquid tank 40 is discharged into the bowl portion 3, so that rinsing cleaning can be performed.

  After rinsing, the mist supply device 35 is stopped by a control signal from the control device 33, and in conjunction with this, the hot air dryer 47 is driven by a control signal from the control device 33 for a certain period of time. The heated air can be blown into the bowl portion 3 by the fan 48 to dry the inside of the bowl portion 3 within a short time.

  Further, the controller 33 continues the decompression by the decompression device 22 until a predetermined time (for example, several tens of seconds) elapses from the stop of the supply of mist by the mist supply device 35, so that the mist remaining in the bowl portion 3 is maintained. Is discharged to the outside together with air, so that when the toilet lid 6 is opened after the decompression of the decompression device 22 is stopped, there is no possibility that the mist floating in the bowl portion 3 is scattered around.

  Further, when the toilet lid 6 is opened during the mist supply, the controller 33 stops the mist supply by the mist supply device 35 and then continues to suck and discharge air for a predetermined time (for example, several tens of seconds). Then, by controlling so that the decompression device 22 is stopped, the mist in the bowl portion 3 is sucked and discharged, and the possibility of scattering around is reduced.

  In the above embodiment, mist is used as the cleaning agent. However, instead of the mist generator 37, an ozone generator or an ion generator may be provided to use micro water droplets carrying ozone or ions having a bactericidal action. it can.

  In the decompression device 22 of the embodiment, since the aspirator 23 that performs suction and discharge using the water flow pressure is used, the decompression device 22 is simple and inexpensive.

  Moreover, since the air containing the mist in the bowl part 3 sucked and discharged to the outside by the aspirator 23 is directly discharged from the drainage channel 19 to the external sewer pipe, it is discharged into the toilet room through the blower fan and the filter. Compared to the case, processing equipment such as a blower fan and a filter is not necessary, and the cost is reduced. In addition, the toilet room is not dampened by moisture from the mist. In particular, when ozone is used as the cleaning agent, air containing ozone can be directly discharged from the drainage channel 19 to the external sewer pipe.

  Further, since the suction pipe 28a and the discharge pipe 28b of the aspirator 23 face the stored water in the lower chamber 24b, the partition plate 25 can be used even if the suction pipe 28a and the discharge pipe 28b run out of water when the pump 28 is stopped. There is no possibility that the air containing the mist collected between the air and the air flows backward from the air suction pipe 30 into the bowl portion 3.

  In the above embodiment, the aspirator 23 is used as the decompression device 22, but a vacuum pump (such as a rotary pump or a diffusion pump) can also be used. Thus, if a vacuum pump that performs suction and discharge using electric power is used, the suction and discharge force and the suction and discharge time can be easily controlled.
