That is, this toilet device can exhaust the odor in the toilet room. Moreover, this toilet device can exhaust the odor of the manure via an air passage in the state which received the manure etc. to the receiving member. For this reason, it is difficult for a user to feel the odor (bad odor) of manure received by the receiving member, and further, the odor can be prevented from diffusing into the toilet room. Further, the closing device opens the discharge part by detecting that the weight of the urine received by the receiving member becomes heavier than the set weight or the dropping of the urine etc. to the receiving member, and the urine from the receiving member Since a discharge part is closed when etc. fall, the time for a closing tool to open a discharge part is a short time. For this reason, the odor in the toilet bowl rising above the closure is slight. As described above, since the odor rising from the toilet bowl to the upper side of the closing tool is slight, the odor can be surely exhausted by driving the blower provided in the air passage. Further, when the closing tool opens the discharge part, the blower can be driven to supply air from the outside to the toilet bowl part through the air passage. When the closing tool temporarily opens the discharge part, an air flow is generated from the discharge part into the toilet bowl. At this time, since the air supplied from the outside through the air path by driving the blower is drawn into the toilet bowl, the air in the toilet bowl is not drawn into the toilet bowl through the discharge section. For this reason, it can prevent that air flows around the user's buttocks seated on the toilet seat provided on the upper surface of the toilet bowl, and can prevent the user from feeling cool.

Therefore, the toilet device according to the fourth aspect of the present invention can be used satisfactorily because the user does not feel bad smell.

<Example 1>
As shown in FIGS. 1 and 2, the toilet apparatus according to the first embodiment includes a toilet body 10, a discharge unit 20, a drainage channel 30, a toilet cleaning device 40, a local cleaning device 50, a detection device 60, a control device 70, and a connection. A device 80 is provided.

The toilet body 10 includes a toilet bowl 11 having a discharge port 11A at the bottom. The toilet bowl 11 has a rim water passage 12 formed on the upper inner periphery of the toilet bowl 11 so that washing water discharged from the rim water discharge pipe 13 flows along the upper inner periphery of the toilet bowl 11. . Since the wash water flowing through the rim water passage 12 gradually flows down along the inner surface of the toilet bowl 11, the entire inner surface of the toilet bowl 11 can be washed with the wash water.

The toilet bowl 11 has a connecting device 80 connected to the discharge port 11A. The connecting device 80 forms a discharge portion 20 that communicates the discharge port 11A with a toilet tank 90 described later. The connecting device 80 has a mortar-shaped inflow portion 81 that connects the upper end opening to the outer peripheral surface of the discharge port 11A, continues from the upper end opening, and opens at the lower end.

The connecting device 80 has a cylindrical intermediate pipe portion 82 below the lower end opening of the inflow portion 81. The intermediate pipe portion 82 has an inclined surface 82A whose upper end portion is inclined obliquely upward from the inner peripheral surface toward the outer peripheral surface, and the upper end opening edge 82B is located above the lower end opening edge 81A of the inflow portion 81. ing. A gap X through which cleaning water passes is formed between the upper inclined surface 82 </ b> A of the intermediate pipe portion 82 and the outer peripheral surface of the lower end portion of the inflow portion 81.

The connecting device 80 has a connecting portion 83 that connects the upper portion of the outer surface of the inflow portion 81 and the outer surface of the intermediate tube portion 82. The connecting portion 83 has a cylindrical outer surface. The connecting device 80 is formed by extending the drainage channel 30 outward from a part of the outer surface of the connecting portion 83. The drainage channel 30 is obtained by branching the discharge part 20 via the gap X and the internal space of the connecting part 83 on the upstream side of a closing tool 85 described later.

The connecting device 80 has an outflow portion 84 that is connected to the outer surface of the intermediate pipe portion 82 and that is open at the lower end. The outflow portion 84 has a substantially cylindrical shape whose diameter gradually decreases downward. The lower end opening of the outflow portion 84 is connected to a through hole 92 provided in the floor surface F on which the toilet body 10 is installed. The through hole 92 communicates with a toilet tank 90 provided below the floor surface F. The toilet bowl 90 is provided below the toilet body 10. The toilet bowl 90 stores a fungus bed 91 for fermenting and decomposing filth. The fungus bed 91 is obtained by culturing aerobic microorganisms in a culture site such as wood chips and sawdust.

The closing tool 85 includes a receiving member 86 and a support member 87. The outflow portion 84 has a rotation shaft portion 87A that rotatably supports the support member 87 on the inner surface of the upper end portion. The receiving member 86 is formed in the shape of a saucer having a disc-shaped central portion and an edge portion that is inclined obliquely upward and outward continuously from the outer peripheral edge portion thereof. An iron weight member 88 is connected to the other end of the support member 87 located on the opposite end side of the receiving member 86 across the rotation shaft portion 87A. The weight member 88 is set to such a weight that the receiving member 86 side does not descend unless the load applied to the receiving member 86 exceeds the set weight.

Therefore, normally (such as a standby state in which the toilet body 10 is not used), the receiving member 86 rises around the rotation shaft portion 87A, contacts the lower end opening edge 82C of the intermediate tube portion 82, and is discharged. The part 20 is closed. On the other hand, the receiving member 86 descends around the rotation shaft portion 87A and opens the discharge 20 when placing a manure or washing water having a weight more than the set weight on the upper surface thereof. When the receiving member 86 is lowered about the rotation shaft portion 87A, the upper surface of the receiving member 86 is inclined almost vertically, so that manure, washing water and the like placed on the upper surface of the receiving member 86 fall, and the toilet tank 90 Is discharged. When manure, washing water or the like placed on the upper surface of the receiving member 86 falls, the receiving member 86 rises around the rotation shaft portion 87A by the weight member 88, so that the receiving member 86 opens at the lower end of the intermediate tube portion 82. The state automatically abuts on the edge 82C and closes the discharge portion 20.

The outflow portion 84 has an electromagnet 89 attached to the outside of the surface with which the weight member 88 abuts in a state where the receiving member 86 abuts the lower end opening edge 82C of the intermediate tube portion 82 and closes the discharge portion 20. When the electromagnet 89 is energized, the weight member 88 is attracted by the magnetic force, so that the receiving member 86 can be locked to a state in which the discharge portion 20 is closed by contacting the lower end opening edge 82C of the intermediate tube portion 82. That is, the electromagnet 89 is a locking device that locks the closing tool 85 in a state in which the discharge portion 20 is closed. Switching between energization and non-energization of the electromagnet 89 is controlled by a control device 70 described later.

The toilet bowl cleaning device 40 includes a water storage tank 41 communicating with the downstream side of the drainage channel 30, and a water supply device 42 that supplies the cleaning water stored in the water storage tank 41 to the toilet bowl 11. The water storage tank 41 has a mesh-like filter member 43 incorporated therein. The drainage channel 30 drawn into the water storage tank 41 has a water outlet above the filter member 43.

The local cleaning device 50 has a nozzle cleaning mechanism for cleaning the cleaning nozzle 51. The nozzle cleaning mechanism has a branch passage that branches a communication passage communicating from the hot water tank 53 to the cleaning nozzle 51 via a switching valve, and the cleaning nozzle 51 that has retreated from the water outlet at the downstream end of the branch passage to the storage position. The cleaning water is discharged toward the front end of the cleaning nozzle 51 to clean the front end of the cleaning nozzle 51. Switching of the switching valve is controlled by a control device 70 described later.

The local cleaning device 50 is housed in the toilet seat box 2 attached to the rear upper surface of the toilet body 10 and assembled to the toilet body 10. The toilet seat box 2 has a shaft support portion that rotatably supports the toilet lid 3 and the toilet seat 4 at the front end. The toilet lid 3 and the toilet seat 4 are rotated between a standing state and a lying state by an electromagnetic motor (not shown). The driving of the electromagnetic motor is controlled by a control device 70 described later.

The toilet seat 4 has a built-in seating detection device. The seating detection device is configured by a capacitive sensor, and can detect the user's seating on the toilet seat 4. The seating detection device transmits a signal indicating whether or not the user is seated on the toilet seat 4 to a control device described later.

Detecting device 60 is attached to the front end of the upper surface of toilet seat box 2. The detection device 60 is configured by an infrared sensor, and can detect a user within a set range in front of the toilet body 10. The detection device 60 transmits a signal indicating the presence or absence of a user to a control device described later.

The control device 70 is accommodated in the toilet seat box 2. The control device 70 includes a receiving unit 70 </ b> A that receives an operation signal transmitted from the remote controller 71. The remote controller 71 is attached to the wall surface W of the toilet room where the toilet body 10 is installed. The remote controller 71 has various operation buttons such as a toilet cleaning button 72, a local cleaning button 73, a stop button 74, a nozzle cleaning button 75, and a cleaning button 76. The remote controller 71 includes a transmission unit 71A that transmits operation signals corresponding to operations of various operation buttons to the reception unit 70A of the control device 70. The remote controller 71 has a lid member 71B that opens and closes a part of the front surface. Less frequently used operation buttons such as the nozzle cleaning button 75 and the cleaning button 76 are provided on the operation surface exposed when the lid member 71B is opened.

The “pre-cleaning”, “drainage”, “local cleaning”, and “toilet cleaning” operations of the toilet apparatus configured as described above will be described with reference to FIG.

[Pre-cleaning]
When the detection device 60 detects that the user who has entered the toilet room is within the set range in front of the toilet body 10, the detection device 60 transmits a detection signal to the control device 70 (step S1). Then, the control device 70 drives the electromagnetic motor to rotate the toilet lid 3 to the upright state, and performs the pre-washing described below.

In pre-cleaning, first, the electromagnet 89 is energized to drive the locking device, and the closing tool 85 is locked in a state in which the discharge unit 20 is closed (step S2). Thereafter, the pump P of the toilet bowl cleaning device 40 is driven for a set time T1 (for example, 0.3 seconds) (step S3). Furthermore, after the drive of the pump P is stopped, the energization to the electromagnet 89 is finished and the lock of the closing tool 85 is released (step S4).

By executing the pre-cleaning, the toilet bowl cleaning device 40 supplies the cleaning water in the water storage tank 41 to the rim water passage 12 of the toilet bowl 11 through the water supply pipe 46 and the rim water discharge pipe 13. Since the wash water flowing through the rim water passage 12 gradually flows down along the inner surface of the toilet bowl 11, the entire inner surface of the toilet bowl 11 can be wetted by the wash water. For this reason, it is possible to make it difficult for dirt and the like to adhere to the inner surface of the toilet bowl 11.

As described above, the execution of the pre-cleaning is intended to make it difficult for filth and the like to adhere to the inner surface of the toilet bowl 11 and the upper surface of the closing tool 85, so that the pre-cleaning is supplied to the toilet bowl 11. The amount of washing water is less than the amount of washing water supplied to the toilet bowl 11 during toilet bowl cleaning described below. Moreover, the wash water supplied to the toilet bowl part 11 by execution of pre-washing and flowed down to the discharge port 11A of the toilet bowl part 11 has a low pollution degree.

While the pump P of the toilet bowl cleaning device 40 is being driven, the weight member 88 is attracted by the magnetic force of the electromagnet 89, and the closing tool 85 is in contact with the lower end opening edge 82 </ b> C of the intermediate pipe portion 82 to close the discharge portion 20. Locked. For this reason, the wash water supplied to the toilet bowl 11 by the pre-washing is not discharged into the toilet tank 90 but overflows from the upper end opening edge 82B of the intermediate pipe part 82 into the connecting part 83 and enters the drainage channel 30. Inflow. Therefore, this toilet apparatus can reduce the water drained to the toilet tank 90. For this reason, it can prevent that the microbial bed 91 accommodated in the toilet tank 90 becomes excessively water, and can perform fermentation decomposition | disassembly of filth etc. favorably.

In addition, this toilet device can store wash water with low pollution flowing into the drainage channel 30 in the water storage tank 41. The wash water stored in the water storage tank 41 is sterilized with chlorine and can be supplied to the toilet bowl 11 by the water supply device 42 and used for toilet flushing. Thus, this toilet apparatus can circulate and reuse the wash water supplied to the toilet bowl 11 by performing pre-washing for toilet flushing.

[Manure discharge]
After completion of the pre-cleaning, the seating detection device transmits a detection signal to the control device 70 when detecting that the user is seated on the toilet seat 4 (step S5). Since the locking of the closing tool 85 is released after the pre-washing is finished, the closing tool 85 can be turned on the pivot shaft portion 86A when manure, washing water, or the like set on the upper surface of the closing tool 85 is placed thereon. And the discharge part 20 is opened.

For this reason, as shown in FIG. 4, when the user H excretes the urine P, and the urine P having a set weight or more is placed on the upper surface of the closure 85, the closure 85 has the rotation shaft portion. It descends around 86A and opens the discharge part 20. When the closing tool 85 is lowered about the rotation shaft portion 86A, the upper surface of the closing tool 85 is inclined almost vertically, so that the urine P or the like placed on the upper surface of the closing tool 85 falls and is discharged to the toilet tank 90. Is done. When the manure P or the like placed on the upper surface of the closing tool 85 falls, the closing tool 85 rises around the rotation shaft portion 86A by the weight member 88, so that the closing tool 85 has a lower end opening edge 82C of the intermediate tube portion 82. It automatically returns to the state in which the discharge part 20 is closed in contact with. Thus, the closing tool 85 repeats opening and closing of the discharge part 20 according to the excretion of the manure P of the user H. The filth discharged to the toilet tank 90 is fermented and decomposed by the fungus bed 91.

[Local cleaning]
When the user presses the local cleaning button 73 of the remote controller 71, a local cleaning signal is transmitted from the transmitting unit 71A to the receiving unit 70A of the control device 70 (step S6). When the receiving unit 70A receives the local cleaning signal, the control device 70 drives the electromagnetic motor to move the cleaning nozzle 51 to the forward position and open the on-off valve V to drive the local cleaning device 50 ( Step S7).

Thereafter, the amount of local washing water ejected from the washing nozzle 51 is detected (step S8), and when the amount of water exceeds the set amount, the control device 70 energizes the electromagnet 89 to drive the lock device, The closing tool 85 is locked in the closed state (step S9).

At this time, the amount of the local cleaning water ejected from the cleaning nozzle 51 is converted by the ejection time in accordance with the flow rate of the local cleaning water ejected from the cleaning nozzle 51, and the control device 70 opens the opening / closing valve V. Is controlling. That is, the controller 70 energizes the electromagnet 89 when the set time has elapsed after opening the on-off valve V.

By opening the on-off valve V, as shown in FIG. 5, the cleaning water supplied from the water supply channel 1 is provided at the tip of the cleaning nozzle 51 that has moved to the forward position via the hot water tank 53. Spraying from the cleaning hole and local cleaning is performed. When the set time elapses after the on-off valve V is opened (when the local cleaning water ejected from the cleaning nozzle 51 after executing the local cleaning exceeds the set water amount), the electromagnet 89 is energized. The weight member 88 is attracted, and the closing tool 85 is brought into contact with the lower end opening edge 82C of the intermediate tube portion 82 to lock the discharge portion 20 in a closed state.

When performing the local cleaning, since the excrement adhering to the user's buttocks is washed away at the initial stage of the cleaning, the local cleaning water flowing into the toilet bowl 11 becomes highly polluted. The local cleaning water having a high degree of contamination is discharged from the closing tool 85 until the closing tool 85 is locked in a state in which the discharging part 20 is closed (until the set time elapses after the opening / closing valve V is opened). Since the local wash water of the amount of water (set water amount) that always opens 20 is ejected from the wash nozzle 51, it is discharged to the toilet tank 90.

The local cleaning device 50 is continuously driven, and when the set time has elapsed after the opening / closing valve V is opened, the local portion falls into the toilet bowl 11 and flows down to the discharge port 11A of the toilet bowl 11. Washing water has low pollution. At this time, since the control device 70 is energizing the electromagnet 89, the closing tool 85 is locked in a state in which the discharge portion 20 is closed. For this reason, the local wash water having a low degree of pollution overflows into the connecting portion 83 from the upper end opening edge 82B of the intermediate pipe portion 82 without being discharged into the toilet tank 90 and flows into the drainage channel 30. For this reason, this toilet apparatus can reduce the water drained to the toilet tank 90. Therefore, it can prevent that the microbial bed 91 accommodated in the toilet tank 90 becomes excessively water, and can perform fermentation decomposition | disassembly of filth etc. favorably.

Further, the local wash water having a low pollution level flowing into the drainage channel 30 is stored in the water storage tank 41. The local wash water stored in the water storage tank 41 is sterilized with chlorine and can be supplied to the toilet bowl 11 by the water supply device 42 and used for toilet flushing. Thus, this toilet apparatus can circulate and reuse a part of the local washing water spouted from the washing nozzle 51 by the execution of the local washing for the toilet bowl washing.

When the user presses the stop button 74 of the remote controller 71 while the local cleaning device 50 is being driven, a stop signal is transmitted from the transmitter 71A to the receiver 70A of the control device 70 (steps S10 and S11). When the receiving unit 70A receives the stop signal, the control device 70 drives the electromagnetic motor to move the cleaning nozzle 51 to the storage position and closes the on-off valve V to stop driving the local cleaning device 50. (Steps S12 and S13). This completes the local cleaning. When the electromagnet 89 is energized, the control device 70 ends the energization of the electromagnet 89 (step S14).

When the local cleaning device 50 is repeatedly driven by pressing the local cleaning button 73 after the user presses the stop button 74 of the remote controller 71, the control device 70 opens and closes the open / close valve each time the stop button 74 is pressed. The valve opening time of V is reset, the valve opening time from the most recent valve opening of the on-off valve V is measured, and when the set time elapses, the electromagnet 89 is energized. This is because there is a possibility that excrement may be excreted after the user presses the stop button 74 of the remote controller 71 and before pressing the local washing button 73.

[Toilet bowl cleaning]
When the user presses the toilet cleaning button 72 of the remote controller 71, a toilet cleaning signal is transmitted from the transmitting unit 71A to the receiving unit 70A of the control device 70 (step S15). When the receiving unit 70A receives the toilet bowl cleaning signal, the control device 70 causes the toilet bowl cleaning described below to be executed.

In the toilet flushing, first, the pump P of the toilet flushing device 40 is driven for a set time T2 (for example, 0.5 seconds) to execute the first toilet flushing (step S16). Next, the electromagnet 89 is energized to drive the locking device, and the closing tool 85 is locked in a state where the discharge part 20 is closed (step S17), and the second toilet flushing is started. Then, the pump P of the toilet bowl cleaning device 40 is driven for a set time T3 (for example, 3.5 seconds) (step S18). Furthermore, after the drive of the pump P is stopped, the energization to the electromagnet 89 is finished, the lock of the closing tool 85 is released (step S19), and the second toilet flushing is finished.

In this way, toilet flushing is performed in which the wash water in the water storage tank 41 is supplied to the rim water passage 12 of the toilet bowl 11 through the water supply pipe 46 and the rim water discharge pipe 13. Since the electromagnet 89 is not energized at the time of cleaning the first toilet bowl, the closing tool 85 has a rotating shaft portion 86A when the urine P, washing water or the like having a weight set on the upper surface thereof is placed. It is in the state which descend | falls centering on and open | releases the discharge part 20. FIG. For this reason, the filth and toilet paper adhering to the inner surface of the toilet bowl 11 and the filth and toilet paper remaining on the upper surface of the closure 85 can be discharged to the toilet tank 90 by the wash water supplied in the first toilet flushing. it can.

The washing water supplied to the toilet bowl 11 during the subsequent second toilet flushing and flowing down to the outlet 11A of the toilet bowl 11 has low pollution. Further, since the electromagnet 89 is energized, the weight member 88 is attracted by the magnetic force of the electromagnet 89, and the closing tool 85 is in contact with the lower end opening edge 82C of the intermediate tube portion 82 to close the discharge portion 20. Locked. For this reason, the wash water supplied to the toilet bowl 11 overflows into the connecting part 83 from the upper end opening edge 82B of the intermediate pipe part 82 without being discharged into the toilet tank 90 and flows into the drainage channel 30. For this reason, this toilet apparatus can reduce the water drained to the toilet tank 90. Therefore, it can prevent that the microbial bed 91 accommodated in the toilet tank 90 becomes excessively water, and can perform fermentation decomposition | disassembly of filth etc. favorably.

Also, the wash water with low pollution flowing into the drainage channel 30 is stored in the water storage tank 41. The wash water stored in the water storage tank 41 is sterilized with chlorine and can be supplied to the toilet bowl 11 by the water supply device 42 and used for toilet flushing. Thus, this toilet apparatus can circulate and reuse a part of the wash water supplied to the toilet bowl 11 by toilet flushing.

When the second toilet flushing is completed and the toilet flushing is completed, when it is detected that the user is no longer within the set range in front of the toilet body 10, a detection signal is transmitted to the control device 70 (step S20). As a result, the toilet device returns to the standby state.

In this toilet device, when the user presses the toilet cleaning button 72 of the remote controller 71 while the local cleaning device 50 is being driven, a toilet cleaning signal is transmitted from the transmitting unit 71A to the receiving unit 70A of the control device 70. At this time, if the local cleaning device 50 is being driven, the control device 70 does not drive the pump P of the toilet cleaning device 40 even if the receiving unit 70A receives the toilet cleaning signal. For this reason, this toilet device does not perform toilet cleaning during local cleaning.

Thus, this toilet device can simplify the control of the control device 70. In addition, the local cleaning water that has flowed into the toilet bowl 11 by driving the local cleaning apparatus 50 may wash away dirt and the like attached to the inner surface of the toilet bowl 11. In this case, since it becomes unnecessary to drive the toilet bowl cleaning device 40 to wash the toilet bowl 11, the use of useless washing water can be prevented and the amount of water drained into the toilet tank 90 can be reduced. it can.

Next, the “nozzle cleaning” operation of the toilet device will be described with reference to FIG.

[Nozzle cleaning]
When the user presses the nozzle cleaning button 75 of the remote controller 71, a nozzle cleaning signal is transmitted from the transmission unit 71A to the reception unit 70A of the control device 70 (step S31). When the receiving unit 70A receives the nozzle cleaning signal, the control device 70 energizes the electromagnet 89 to drive the locking device, and locks the closing tool 85 in a state where the discharge unit 20 is closed (step S32). And the control apparatus 70 switches a switching valve so that washing water may flow into a branched water channel for a set time, and opens the on-off valve V (step S33). As a result, as shown in FIG. 7, the cleaning water supplied from the water supply channel 1 is directed toward the tip of the cleaning nozzle 51 that has retreated to the storage position via the hot water tank 53, the switching valve, and the branch water channel. Nozzle cleaning is performed to discharge water. After the set time has elapsed and the nozzle cleaning has ended, the control device 70 ends the energization of the electromagnet 89 and releases the lock of the closing tool 85 (step S34).

The nozzle cleaning water that has cleaned the cleaning nozzle 51 by flowing through the nozzle 11 and discharged to the outlet 11A of the toilet bowl 11 has low pollution. Further, during the nozzle cleaning, the weight member 88 is attracted by the magnetic force of the electromagnet 89, and the stopper 85 is brought into contact with the lower end opening edge 82C of the intermediate tube portion 82 to lock the discharge portion 20 in a closed state. Yes.

For this reason, the nozzle washing water having a low degree of pollution overflows into the connecting portion 83 from the upper end opening edge 82B of the intermediate pipe portion 82 without being discharged into the toilet tank 90, and flows into the drainage channel 30. Therefore, this toilet apparatus can reduce the water drained to the toilet tank 90. For this reason, it can prevent that the microbial bed 91 accommodated in the toilet tank 90 becomes excessively water, and can perform fermentation decomposition | disassembly of filth etc. favorably.

Further, the nozzle cleaning water having a low pollution level that has flowed into the drainage channel 30 is stored in the water storage tank 41. The nozzle washing water stored in the water storage tank 41 is sterilized with chlorine and can be supplied to the toilet bowl 11 by the water supply device 42 and used for toilet flushing. Thus, this toilet device can be reused by circulating nozzle cleaning water for toilet cleaning.

Next, the “cleaning washing” operation of the toilet apparatus will be described with reference to FIG.

[Cleaning and washing]
When the user presses the cleaning button 76 of the remote controller 71, a cleaning cleaning signal is transmitted from the transmitting unit 71A to the receiving unit 70A of the control device 70 (step S41). When the receiving unit 70A receives the cleaning signal, the control device 70 energizes the electromagnet 89 to drive the locking device, and locks the closing tool 85 in a state in which the discharging unit 20 is closed (step S42). And the control apparatus 70 drives the pump P of the toilet bowl washing | cleaning apparatus 40 during setting time (step S43). As a result, cleaning cleaning is performed in which the cleaning water in the water storage tank 41 is supplied to the rim water passage 12 of the toilet bowl 11 through the water supply pipe 46 and the rim water discharge pipe 13. After the set time has elapsed and the cleaning cleaning has ended, the control device 70 ends energization of the electromagnet 89 and unlocks the closing tool 85 (step S44).

The washing water supplied to the toilet bowl 11 by the execution of cleaning and flowing down to the discharge port 11A of the toilet bowl 11 has low pollution. Further, during the cleaning and cleaning, the weight member 88 is attracted by the magnetic force of the electromagnet 89, and the closing tool 85 abuts against the lower end opening edge 82C of the intermediate tube portion 82 to lock the discharge portion 20 in a closed state. Yes.

For this reason, the wash water having a low degree of pollution overflows into the connecting portion 83 from the upper end opening edge 82B of the intermediate pipe portion 82 without being discharged into the toilet tank 90 and flows into the drainage channel 30. Therefore, this toilet apparatus can reduce the water drained to the toilet tank 90. Moreover, this toilet apparatus can prevent the washing water mixed with the cleaning agent used at the time of cleaning and cleaning from being drained to the toilet tank 90. For this reason, since the microbial bed 91 accommodated in the toilet tank 90 can be prevented from becoming excessively watery, and aerobic microorganisms can be prevented from being killed by the cleaning agent, Fermentative decomposition can be performed satisfactorily.

Further, the nozzle cleaning water having a low pollution level that has flowed into the drainage channel 30 is stored in the water storage tank 41. The nozzle washing water stored in the water storage tank 41 is sterilized with chlorine and can be supplied to the toilet bowl 11 by the water supply device 42 and used for toilet flushing. In this way, this toilet device can be reused by circulating the wash water supplied to the toilet bowl 11 during cleaning and cleaning for toilet bowl cleaning.

<Example 2>
As shown in FIG. 10, in the toilet cleaning operation of the second embodiment, when the local cleaning water ejected from the cleaning nozzle 51 by driving the local cleaning device 50 in the “local cleaning” operation exceeds the set water amount, The point which drives the toilet bowl washing | cleaning apparatus 40 before supplying the local wash water which flowed out in the drainage channel 30 and supplies the wash water of the set amount of water to the toilet bowl part 11 (step S21) is different from Example 1. To do. Other configurations are the same as those in the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

In this toilet apparatus, in the “local cleaning” operation, the user presses the local cleaning button 73 of the remote controller 71 (step S6), the local cleaning apparatus 50 is driven (step S7), and the local cleaning ejected from the cleaning nozzle 51 is performed. When the amount of water exceeds the set amount, the pump P of the toilet bowl cleaning device 40 is driven for a set time T4 (for example, 0.4 seconds) to supply the set amount of wash water to the toilet bowl 11 ( Step S21). Thereafter, the control device 70 energizes the electromagnet 89 to drive the locking device, and locks the closing tool 85 in a state where the discharge unit 20 is closed (step S9).

In this way, in the “local washing” operation, this toilet device locks the closing tool 85 in a state in which the locking device is driven to close the discharge unit 20, and drains the local washing water that has flowed out into the toilet bowl 11. Since the pump P of the toilet bowl cleaning device 40 is driven before the flow into the passage 30 to supply the set amount of flush water to the toilet bowl 11, the urine in the toilet bowl 11 and the highly contaminated flush water are completely removed. It is possible to drain into the toilet tub, and the contamination of the local wash water flowing into the drainage channel 30 can be reliably reduced.

The first to third inventions are not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.
(1) In Examples 1 and 2, the drainage channel communicates the downstream end with the water storage tank and circulates and reuses the wash water stored in the water storage tank for toilet flushing. The waste water may be drained by communicating with a waste water treatment device for treating the waste water. In this case, the wash water used for toilet flushing may be supplied from a water supply channel communicating with the water pipe.
(2) In Examples 1 and 2, the fungus bed is stored in the toilet bowl, but it may be a draw-up type toilet tank that does not store the fungus bed. Even in this case, this toilet device is effective because it can reduce the amount of water drained to the toilet.
(3) In Examples 1 and 2, the flushing water was allowed to flow into the drainage channel without draining into the toilet tub by locking the discharge portion in the closed state with the closure, but the flushing water was not drained into the toilet tub. Any other configuration may be used as long as it can flow into the drain.
(4) In Examples 1 and 2, pre-cleaning is performed when the detection device detects a user in front of the toilet body, but pre-cleaning is performed when the seating detection device detects that the user is seated on the toilet seat. It may be a thing.
(5) In the first and second embodiments, the toilet cleaning device can perform pre-cleaning, but the toilet cleaning device may not have a pre-cleaning function.
(6) In the first and second embodiments, the local cleaning device is capable of performing nozzle cleaning, but may be a local cleaning device having no nozzle cleaning function.
(7) In the first and second embodiments, the toilet cleaning device can perform cleaning and cleaning. However, the toilet cleaning device may not have a cleaning and cleaning function.

Next, a preferred embodiment in the fourth invention will be described.

A connecting device for forming the discharge portion of the fourth invention is provided, and the connecting device is provided with the closing tool, and the air path can be communicated with the connecting device above the closing tool. In this case, the toilet device can be easily constructed.

A drainage channel branched above the closure is provided, and the air channel can be connected to the drainage channel. In this case, the water that has flowed into the toilet bowl via the drainage channel can be discharged. Moreover, odor can be exhausted using this drainage channel, or air can be supplied to the toilet bowl from the outside.

A human body detection device that detects the presence or absence of a user is provided, and the blower can change the flow rate of air exhausted through the toilet bowl and the air passage according to the presence or absence of a user detected by the human body detection device. In this case, when the human body detection device is detecting the user, the flow rate of the air exhausted by the blower through the toilet bowl and the air passage can be increased. If it does in this way, the odor in a toilet room can be exhausted quickly and it can make a user hard to feel a bad odor. Moreover, when the human body detection apparatus is not detecting the user, the electric power consumption of an air blower can be suppressed by reducing the flow volume of the air which an air blower exhausts via a toilet bowl part and an air path. In addition, if the air exhausted by the blower through the toilet bowl and the air passage flows around the user's buttocks, etc., giving the user a cool feeling, the human body detection device is used by the user. When air flow is detected, the flow rate of air exhausted by the blower through the toilet bowl and the air passage may be reduced.

The apparatus includes a temperature detection device that detects an ambient temperature in which the toilet bowl portion is disposed, and the blower has a flow rate of air exhausted through the toilet bowl portion and the air passage according to a temperature detected by the temperature detection device. Can change. In this case, when the temperature detected by the temperature detection device is higher than the set temperature, the flow rate of the air exhausted by the blower through the toilet bowl and the air passage is increased. If it does in this way, in the summer etc., the air which flows into the toilet bowl part from the inside of a toilet room will flow the circumference | surroundings of the user's buttocks seated on the toilet seat provided in the upper surface of the toilet bowl part, and it can give a cool feeling. Moreover, when the temperature which a temperature detection apparatus detects is lower than preset temperature, the flow volume of the air which a fan exhausts via a toilet bowl part and an air path is decreased. In this way, in winter and the like, the air flowing from the toilet room into the toilet bowl is reduced, so the air flowing around the user's buttocks seated on the toilet seat provided on the upper surface of the toilet bowl is reduced, A cool feeling can be suppressed.

The blower can supply air from the outside to the toilet bowl through the air passage when the closing member opens the discharge part. In this case, when the closing tool temporarily opens the discharge part, an air flow is generated from the discharge part into the toilet. At this time, since the air supplied from the outside through the air passage by driving the blower is drawn into the toilet bowl, the air in the toilet bowl is not drawn into the toilet bowl through the discharge section. For this reason, it can prevent that air flows around the user's buttocks seated on the toilet seat provided on the upper surface of the toilet bowl, and can prevent the user from feeling cool. Moreover, it is possible to prevent the odor in the toilet bowl from rising above the closing tool.

The flow rate of air supplied by the blower may be equal to or less than the flow rate of air flowing from the discharge unit to the toilet bowl when the closing member opens the discharge unit. In this case, it is possible to prevent the flow rate of air supplied by the blower from being excessive and flowing to the toilet bowl side. For this reason, it can prevent giving a user discomfort.

In a state where the closing tool closes the discharge part, the receiving member can store the water on its upper surface while communicating the stool part and the air passage. In this case, the odor in the toilet bowl is reliably prevented from rising due to the water stored in the receiving member, and the air in the toilet room is exhausted through the toilet bowl and the air passage by driving the blower. be able to.

Next, Embodiments 3 to 6 embodying the toilet device of the fourth invention will be described with reference to the drawings.

<Example 3>
As shown in FIG. 11, the toilet apparatus according to the third embodiment includes a toilet bowl 11, a discharge unit 20, a closing tool 85, an air passage 100, and a fan 110 that is a blower. The toilet bowl 11 is provided in the toilet bowl body 10 and opens upward. Moreover, the toilet bowl part 11 has the discharge port 11A penetrated by the lowest end part. The toilet body 10 has a toilet lid 3 and a toilet seat 4 provided above the toilet bowl 11.

The toilet body 10 is installed on the floor F in the toilet room. Below the floor F, a toilet tank 90 is provided. The floor surface F has a through hole 92 penetrating below the outlet 11A of the toilet bowl 11. The through hole 92 is connected by inserting a lower end of a connecting device 80 described later. The toilet bowl 90 can store the urine F dropped from the through hole 92.

The toilet bowl 11 has a connecting device 80 connected to the discharge port 11A. The connecting device 80 forms a discharge portion 20 that connects the discharge port 11A to the toilet tank 90. The connecting device 80 has a mortar-shaped inflow portion 81 that connects the upper end opening to the outer peripheral surface of the discharge port 11A, continues from the upper end opening, and opens at the lower end.

The connecting device 80 has a cylindrical intermediate pipe portion 82 below the lower end opening of the inflow portion 81. The intermediate pipe portion 82 has an inclined surface whose upper end portion is inclined obliquely upward from the inner peripheral surface toward the outer peripheral surface, and the upper end opening edge is located above the lower end opening edge of the inflow portion 81. Further, the intermediate pipe portion 82 has a gap formed between the inclined surface formed at the upper end portion and the outer peripheral surface of the lower end portion of the inflow portion 81.

The connecting device 80 has a connecting portion 83 that connects the upper portion of the outer surface of the inflow portion 81 and the outer surface of the intermediate tube portion 82. The connecting portion 83 has a cylindrical outer surface. The connecting device 80 is formed by extending the air passage 100 outward from a part of the outer surface of the connecting portion 83. As described above, the air passage 100 communicates with the connection device 80 in the vicinity of the upstream side of the closing tool 85 described later, that is, above the closing tool 85. Since the air passage 100 is communicated with the connecting device 80, the toilet device can be easily constructed.

The connecting device 80 has an outflow portion 84 that is connected to the outer surface of the intermediate pipe portion 82 and that is open at the lower end. The outflow portion 84 has a substantially cylindrical shape whose diameter gradually decreases downward. The lower end opening of the outflow portion 84 is connected to a through hole 92 provided in the floor surface F.

The closing tool 85 includes a receiving member 86 and a support member 87. The receiving member 86 is formed in the shape of a saucer having a disc-shaped central portion and an edge portion that is inclined obliquely upward and outward continuously from the outer peripheral edge portion thereof. The support member 87 supports the receiving member 86 at one end and connects a weight member 88 to the other end. The support member 87 is pivotally supported on the weight member 88 side so as to be rotatable. When the receiving member 86 is raised, the upper surface of the receiving member 86 comes into contact with the lower end edge of the intermediate tube portion 82 and closes the discharge portion 20. In addition, the weight of the weight member 88 is set so that the receiving member 86 descends to open the discharge portion 20 when the receiving member 86 receives the urine F of the set weight or more. Further, when the urine F falls from the receiving member 86, the receiving member 86 rises and closes the discharge unit 20.

The toilet device includes an open / close detection device S1 that detects a state in which the closing tool 85 opens and closes the discharge unit 20. The opening / closing detection device S1 transmits a detection signal to the control device C.

The air passage 100 is between the connecting portion 83, the inclined surface formed at the upper end portion of the intermediate pipe portion 82, and the outer peripheral surface of the lower end portion of the inflow portion 81, with the closing tool 85 closing the discharge portion 20. The stool portion 11 communicates with the formed gap and the inflow portion 81. The air passage 100 extends outside through the wall surface W of the toilet room. The air passage 100 is provided with a fan 110 on the way. The fan 110 can change the rotation speed or change the rotation direction according to a control signal transmitted from the control device C. The fan 110 can change the flow rate of air sucked and blown by changing the rotation speed. In addition, the fan 110 changes the rotation direction to suck air from the connection device 80 side and exhaust it to the outside, or sucks outdoor air and supplies it to the connection device 80 side (toilet bowl 11 side). You can mind.

The toilet device includes a temperature detection device S2 that detects the temperature in the toilet room in which the toilet body 10 having the toilet bowl 11 is disposed. The temperature around the toilet body 10 having the toilet bowl 11 can be detected by the temperature detection device S2. The temperature detection device S2 transmits a detection signal to the control device C.

The control device C receives the detection signals of the open / close detection device S1 and the temperature detection device S2, and transmits a control signal to the fan 110 based on the received signals. As a result, the fan 110 is driven as will be described below.

When the opening / closing detection device S1 detects that the closing tool 85 closes the discharge part 20, the control device C controls the fan 110 so as to suck and exhaust air from the connection device 80 side. Thereby, the toilet device can exhaust the air in the toilet room to the outside via the toilet bowl 11, the connection device 80, and the air passage 100. That is, this toilet device can exhaust the odor in the toilet room to the outdoors. In addition, this toilet device can receive the urine from the receiving member 86, and the odor of the manure can be exhausted to the outside through the connection device 80 and the air passage 100. For this reason, it is difficult for the user to feel the odor (bad odor) of manure received by the receiving member 86, and further, the odor can be prevented from diffusing into the toilet room.

Further, when the temperature in the toilet room detected by the temperature detection device S2 is higher than the set temperature, the control device C controls the fan 110 so as to increase the rotation speed of the fan 110. Thereby, the flow volume of the air in the toilet room which exhausts outdoors via the toilet bowl part 11, the connection apparatus 80, and the air path 100 increases. In summer or the like, by increasing the flow rate of air flowing from the toilet room into the toilet bowl 11, the air flows around the user's buttocks seated on the toilet seat 4 and can give a cool feeling. Further, when the temperature in the toilet room detected by the temperature detection device S2 is lower than the set temperature, the control device C controls the fan 110 so as to reduce the rotation speed of the fan 110. Thereby, the flow volume of the air in the toilet room exhausted outdoors through the toilet bowl part 11, the connection apparatus 80, and the air path 100 decreases. In winter and the like, by reducing the flow rate of air flowing from the toilet room into the toilet bowl 11, the air flowing around the buttocks of the user seated on the toilet seat 4 is reduced, and a cool feeling can be suppressed.

Moreover, since the closing tool 85 closes the discharge part 20 when manure falls from the receiving member 86, the time for the closing tool 85 to open the discharge part 20 is short. For this reason, the odor in the toilet bowl 90 rising above the closing tool 85 is slight. Thus, since the odor rising from the toilet bowl 90 above the closing tool 85 is slight, the odor can be reliably exhausted to the outdoors via the air passage 100 by driving the fan 110.

Further, the closing tool 85 temporarily opens the discharge part 20 when the weight of the urine received by the receiving member 86 becomes heavier than the set weight. Then, the opening / closing detection device S1 detects that the closing tool 85 has opened the discharge portion 20, and the control device C causes the fan 110 to pass outdoor air through the air passage 100 on the connection device 80 side (toilet bowl 11 side).

For this reason, the odor in the toilet bowl 90 can be prevented from rising above the closing tool 85.

In addition, when the closing tool 85 temporarily opens the discharge unit 20, air flows around the user's buttocks seated on the toilet seat 4 due to the flow of air drawn into the toilet bowl 90, and a cool feeling is felt. Although the fan 110 causes the outdoor air to flow to the connection device 80 side, the air is drawn into the toilet tub 90 to prevent the air from flowing around the buttocks of the user seated on the toilet seat 4 It is possible to prevent the user from feeling cool.

Therefore, the toilet device of Example 3 is less likely to feel bad smell by the user and can be used satisfactorily.

<Example 4>
The toilet apparatus of Example 4 is provided with the toilet bowl washing | cleaning apparatus 40, as shown in FIG. The toilet bowl cleaning device 40 includes a drainage channel 30, a water storage tank 41 that communicates with the downstream side of the drainage channel 30, and a water supply device 42 that supplies cleaning water stored in the water storage tank 41 to the toilet bowl 11. In addition, the toilet device includes a human body detection device S3 that detects the presence or absence of a user. The toilet device further includes a toilet seat device 5 having a deodorizing device 6 built in a toilet seat box 2 that pivotally supports a toilet lid 3 and a toilet seat (not shown). In other words, this toilet device includes a toilet device having a deodorizing function. In addition, the toilet device includes a lock mechanism (not shown) that locks the closing tool 85 in a state where the discharge unit 20 is closed. This toilet device communicates an air passage 101 with an upstream portion of the drainage passage 30. The same configurations as those of the third embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

The drainage channel 30 extends from a part of the outer surface of the connecting portion 83 of the connecting device 80. The drainage channel 30 communicates with a water storage tank 41 installed outside through the wall surface W of the toilet room.

The water supply device 42 has a water supply pipe 46 provided with a water supply port in the lower part of the water storage tank 41 and a pump P provided in the middle of the water supply pipe 46. The water supply pipe 46 has a downstream end connected to the upstream end of the rim water discharge pipe 13. The water supply device 42 drives the pump P to supply cleaning water (medium water) in the water storage tank 41 to the toilet bowl 11 through the water supply pipe 46 and the rim water discharge pipe 13 to perform toilet flushing.

After the toilet bowl cleaning is performed and toilet paper attached to the surface of the toilet bowl 11 or the urine received by the receiving member 86 is dropped into the toilet bowl 90, the lock mechanism locks the closing tool 85. Thereafter, the toilet flushing water received by the receiving member 86 is drained from a gap formed between the inclined surface formed at the upper end portion of the intermediate pipe portion 82 of the connecting device 80 and the outer peripheral surface of the lower end portion of the inflow portion 81. It flows into the path 30. The toilet flushing water flowing into the drainage channel 30 is stored in the water storage tank 41. The water storage tank 41 incorporates a filter member and a chlorine sterilizer, and stores middle water purified from toilet flushing water. The water storage tank 41 communicates with the water pipe S. When the amount of medium water stored in the water storage tank 41 is reduced, the water can be supplied into the water storage tank 41.

When the toilet bowl cleaning is completed, the lock mechanism unlocks the closing tool 85. In this state, the receiving member 86 can store a set amount (set weight) of toilet flushing water on its upper surface. In the state where the toilet flushing water of the set water amount is stored in the receiving member 86, the lower end edge of the intermediate pipe portion 82 is submerged in the toilet flushing water stored on the upper surface of the receiving member 86. Thereby, it is possible to reliably prevent the odor in the toilet tank 90 from rising through the discharge unit 20.

For this reason, the odor in a toilet room can be exhausted quickly and it can make a user hard to feel a bad odor. Further, when the human body detection device S3 does not detect a user in front of the toilet body 11, the control device C controls the fan 111 so as to reduce the rotational speed of the fan 111. If it does in this way, the flow volume of the air in the toilet room exhausted outdoors via the toilet bowl part 11, the connection apparatus 80, and the air path 101 will decrease. Further, power consumption of the fan 111 can be suppressed.

The deodorizing device 6 sucks air from the toilet bowl 11, passes the sucked air through a deodorizing material such as activated carbon, removes the odor, and exhausts it into the toilet room. When the human body detection device S3 detects a user in front of the toilet body 11, the control device C controls to drive the deodorizing device 6. Further, when the human body detection device S3 does not detect the user in front of the toilet body 11, the control device C controls the deodorizing device 6 to stop. The control device C can control the fan 111 in conjunction with the deodorizing device 6. That is, when the deodorizing device 6 is driven, the control device C controls the fan 111 so that the fan 111 sucks and exhausts air from the connection device 80 side, and when the deodorizing device 6 is stopped. The control device C can control the fan 111 to stop. For this reason, the synergistic effect with the deodorizing apparatus 6 can make a user more difficult to feel bad odor. Further, power consumption of the fan 111 can be suppressed.

Thus, the toilet device of Example 4 can be used well because the user does not feel bad odor.
